LABELS Inventor label-attaching means moves to a position in which the supporting portion thereof is located in the opening of the holding means, and presses the adhesive label against the surface portion ofthe object covering the opening.
PATENTEDUET 26 Ian SHEET 30F 4 IN VE N TOR kuur somorL 72! 6 Mfulf/vr 017 APPARATUS FOR ATTACI'IING ADHESIVE LABELS BACKGROUND OF THE INVENTION Apparatus is known for attaching adhesive labels to objects. The U.S. Pat. No. 2,933,216 discloses an apparatus in which labels are placed on a conveyor with the adhesive face on top, so that objects can be pressed from above against the labels which adhere to the same.
The U.S. Pat. No. 3,265,553 discloses an apparatus in which labels with the adhesive face on top are placed on an elastic roller. The object is manually held against a label on the roller so that the label adheres to the object.
The labelling apparatus according to the prior art is not suitable for attaching labels to cylindrical or spherical surfaces of objects.
SUMMARY OF THE INVENTION It is one object of the invention to provide an apparatus for attaching adhesive labels to objects having a convex and curved surface, such as oranges, apples, lemons, grape fruits, bananas, cucumbers, bottles, balls, etc.
Another object of the invention is to provide apparatus for attaching adhesive labels in rapid succession to objects.
Another object of the invention is to provide an apparatus which can be adapted for attaching labels to differently curved surfaces of objects.
Another object of the invention is to provide an apparatus which automatically attaches adhesive labels to objects successively supplied by a chute.
Another object of the invention is to provide an apparatus which permits the attaching of adhesive labels to a great number of objects within a predetermined time limit, and under the control of an unskilled operator.
With these objects in view, the present invention relates to an apparatus for attaching adhesive labels in which single labels are successively deposited upon a label-attaching means which is moved into an opening in a holder for an object to press the label with its adhesive face against the surface portion of the object covering the opening.
One embodiment of the invention comprises holding means for an object, such as a fruit, and having an opening covered by a surface portion of an object in the holding means; labelattaching means having a supporting portion located opposite the opening; means for depositing labels having adhesive surfaces successively on the supporting portion so that the adhesive face confronts the opening; and mounting means for mounting at least the label-attaching means for movement toward and away from the holding means between an inoperative position, and a label-attaching position in which the supporting portion and a label thereon are located in the opening of the holding means. Consequently, when the label-attaching means moves to the label-attaching position, the label on the supporting portion is pressed against the surface portion of the object covering the opening, and attached to the object.
In the preferred embodiment, the holding means is dished and located above the label-attaching means. The opening is provided in the bottom portion of the holding means, and is vertically aligned with the supporting portion of the label-attaching means. Consequently, the label-attaching means moves along a substantially vertical path to the label-attaching position.
Preferably, the mounting means mount also the holding means for movement toward and away from the label-attaching means between an inoperative position and an operative position. Operating means are actuated by the holding means in the operative position to move the label-attaching means to the label-attaching position, and to actuate the depositing means to place a label on the supporting portion of the label-attaching means.
The depositing means include guide means for guiding the web and labels adhesively attached to the bottom face of the web along a path in which deflector means are located adjacent the supporting portion of the label-attaching means for deflecting successive portions of the web so that the label on the deflected portion is deposited on the supporting portion with its adhesive face confronting the opening in the holding means.
It is advantageous to provide a resilient cushion, which may consist of an elastomer foam, on the supporting portion, and provide the cushion with a concave surface matching the convex shape of an object, such as a bottle or fruit. The holding means is dished, and preferably lined with an elastic material to match the shape of the object. For apples, oranges and grape fruit, the holding means advantageously has the form of part of a sphere, while an elongated trough is used for bananas, cucumbers and bottles.
In one embodiment of the invention, the operating means, which is actuated by the holding means when the same are displaced by the weight of the object, or by manual pressure, include a switch, and an electromagnetic means for actuating the label-attaching means and the transporting means for the web carrying the labels.
In another embodiment, the operating means include mechanical linkages connecting the holding means with the label-attaching means and with the transporting means for the label-carrying web.
The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawing.

FIG. 5 is a fragmentary front view, partially in vertical section, illustrating a part of the apparatus shown in FIG. 4.
DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring first to FIGS. 1 to 3, labels 1 have adhesive faces with which they are attached to a carrier web 2 spaced the same distance from each other. A transporting slide 20, which will be described hereinafter in greater detail, stepwise moves the web 2 over guide means which include the deflector edge or roller 8 at which the web is deflected substantially so that the adhesive labels separate from the web and are successively deposited on a supporting portion 10 in the form of an elastic cushion consisting of an elastomer foam. On one label 1' is located at any time on the supporting portion 1%. whereupon the labebattaching means 3, of which elastic cushion I0 is a portion, is moved upward to a label-attaching position in which supporting portion 10 is located in an opening 4 of a holding means 5 so that label 1' is pressed against the surface of an object 6 and attached to the same in a manner which will be described hereinafter in greater detail.
The elastomer foam cushion l0 assures that the label 1 is pressed with its entire adhesive face uniformly against the co" vex curved surface of the object 6. If the object has a cur ed surface having a small radius of curvature, for example, a small bottle, a lipstick and the like, it is advantageous to provide the elastic supporting portion 10 with a concave surface matching the curvature of the respective object 6 so that the edges of the labels are pressed against the object with the same force as the central portions of the labels.
The holding means 5 is a dished bowl or trough, depending on the shape of the object. When the objects are oranges.
lemons, apples, tangerines, grape fruits and the like, the dished holder 5 has the form of a partial sphere. For elongated objects, such as cucumbers or bottles, the holder is a dished partially cylindrical, trough. In order to prevent damage to soft fruit, such as pears, an elastic lining 11 is provided in holding means 5.
The holding means includes in addition to the dished holder 5, a pair of vertical posts l4 which are guided on opposite sides of the label-attaching means 3 in a supporting frame 9. Below label-attaching means 3, the guiding posts 14 are connected by a horizontal bar 15 which passes through an elongated slot 16 at one end of the longer arm of a double-armed lever 17 whose shorter arm 18 carries a stud l9. Lever 17 is mounted on pivot means 13 on the supporting frame 50 of the machine.
At the end of lever arm 18, a stud 19 is mounted which is guided in a slanted slot 22 in a clamping slide 20 which is guided in slot 21 of supporting frame and housing 50 and is operated by lever 17 to reciprocate.
Downward movement of holding means 5 with post 14 and bar l5 causes turning of lever 17 about pivot 13 so that stud 19 moves upward and displaces transporting slide 20 to the left as viewed in FIG. 1. When holding means 5 is moved upward, the motions are reversed, and transporting slide 20 is moved to the right as viewed in FIG. 1.
Transporting slide 20 has a clamping member 24 mounted on a pivot 23 and having a free end with an elastic clamping bar 25. Web 2 with label I is guided under the top plate 200 of transporting slide 20 but above clamping bar 25 of clamping means 24, and due to the slanted position of clamping means 24, the web is clamped during movement of transporting slide 22 to the right, and released during movement of transporting slide to the left. Consequently, web 2 is transported by transporting slide 20 when holding means 5 moves from the lower operative position to the upper inoperative position.
A second clamping means 28 is mounted by pivot 27 on the supporting frame 50 and is positioned to claim web 1 while transporting slide 20 is moved to the left, so that web 2 is not transported while holding means 5 moves downward to its operative position and effects movement of transporting slide 20 to the left as viewed in FIG. 1.
Transporting slide 20 and its top plate 20a is guided in a housing part 29 which is mounted on a housing wall 30 for angular movement, or generally detachable. The lower ends 22 of the guide slots of transporting slide 20 are opened, so that studs 19 of lever 17 can move out of slots 22 when housing part 29 with transporting slide 20 is detached, or folded back for the purpose of servicing or repairing the transporting slide Label-attaching means 3 is mounted in housing portions 9 for upward movement in slanted slots 40, and is supported by the shorter arm 41 of a double-armed lever 42 which is mounted on the supporting frame by means of a pivot 43. The longer arm 44 of support lever 42 has a position of rest in which it abuts a stop 45 on housing portion 91 due to the action of a spring 46 which is attached at its upper end to labelattaching means 3, while the lower end of spring 46 is secured to a rod 88 having a threaded end portion secured to the bottom plate 31 of the housing. Engaging portion 49 of lever arm 44 is located between stop 45 and wall 30 of the housing, and stop 45 is positioned so that the top face of engaging portion 49 is flush with the upper edge of housing wall 30 of housing 50. Engaging portion 49 is located opposite a roller 48 mounted on a pivot 54 of a projecting portion 47 of holding means 5. When holding means 5 is pressed downward by manual pressure on the object 6, roller 48 engages engaging portion 49 and turns support lever 42 in counterclockwise direction so that the roller 51 on arm 41 urges label-attaching means 3 with the elastic support portion upward until the raised supporting portion 10 with a label 1' thereon abuts the surface portion 6a of the object 6 covering the opening 4 in holding means 5. The axes of support lever 42, of roller 54, and of roller SI are parallel and substantially horizontal.
Directly above the elastic supporting portion 10 of label-attaching means 3, and slightly above the top surface of support portion 10, a device 55 for guiding the label 1 at the moment of transfer from the web 1 to the supporting portion 10 is provided. As also shown in FIGS. 2 and 3, the guiding device 55 has two guide members 55 which include an angular lever mounted on pivot screws 56, and projecting wings having slanted guide edges 57. The wings are made of a material to which the adhesive used on the labels 2 does not adhere when the guide edges 57 engage the edges of labels 1 separating from web 2 due to the deflection obtained by the deflecting means 8. Guide edges 57 extend from the ends of the deflecting roller 8 toward each other, and guide the labels successively to the top face of the supporting portion 10. During the transport of the web with the labels, the wings of guide members 55 are located above the top surface of supporting portion 10, and prevent that the label separating from web 2, but still adhering with its trailing edge to the web, folds back onto web 2 with the adhesive face downward.
The slanted guide edges 57 are particularly useful for guiding round, square, or rhomoid labels which are centered while separating from the web so that the label 1' always has the same position on the supporting portion 10.
As best seen in FIG. 1 and 3, the upper portions of guide posts 14 are provided with camming edges 59. When holding means 5 is pressed downward, camming edges 59 engage lever arms 60 which are connected with guide members 55 and move the wings of guide members 55 away from each other, while springs 86 are tensioned. Shortly before label-attaching means 3 is moved upward due to the action of holding means 5 on support lever 42, guide members 55 are spaced sufficiently to permit support portion 10 and label-attaching means 3 to move between the wings and guide edges 57 upward toward the opening 4 in holding means 5.
Guide members 55 can also be manually separated, since the ends 60' of lever arm 60 project laterally out of walls 30, see FIGS. 2 and 3, so that manual pressure on portions 60 effects separation of the guide members, which is advantageous when a new web I with labels 2 is to be threaded into the apparatus.
The end of a new web 1 is inserted into a channel between two guide plates until the leading end of the web is located under the deflecting roller 8, and above the top face of the elastic support portion 10. A few labels 1 are detached from web 2, and the same is guided over a guide roller 66 and an ad justable roller 67 and through the channel 68 under top plate 20a of transporting slide 20 until the web projects out of the channel 69 in the movable housing portion 29. At the beginning of the operation, no labels are attached to the web between the deflector roller 8 and the leading end of web 2 in channel 69.
While the web 1 with label 2 is inserted into channel 65 and bent l80 about the deflector roller 8, the guide members 55 are manually held in a spaced position so that they do not obstruct the threading in of the web. Clamping means 24 and 28 open automatically during movement of the newly inserted web 2 to the right as viewed in FIG. 1.
Web I with labels 2 is supplied from a supply reel, not shown, mounted on an arm 95 secured to housing wall 30. Between the supply reel and the channel 65, a roller 70 engages the web. Roller 70 is rotatably mounted on a lever arm 72 having a slot 74. A supporting journal 71 passes through slot 74 so that lever arm 72 is movable in longitudinal direction, but can also be turned with roller 70. Lever arm 72 is pivotally connected with an angular lever 75 which turns about the pivot 76 on housing 50. The other end of angular lever 75 is connected with the end of a long angular lever 77 mounted on housing 30 by means of a pivot 78. The end of lever 77 has a slot in which the bar 15, connecting posts 14 of holding means 5, is located so that downward movement of holding means 5 effects outward movement of guide roller 70 whereby a loose loop is formed between the supply reel. not shown, and the entrance opening of channel 65.
When holding means 5 moves again upward to the inoperative position, transporting slide 20 is moved by lever 17 to the right, as viewed in FIG. 1, in a transporting direction so that the label on the deflected portion of the web is deposited on the top surface of supporting portion in the position 1'. The transporting step of the web takes up the slack of the web loop formed by the guide roller 70. Consequently, the transporting slide 20, 20a, 24 does not have to pull the web off the supply reel, not shown, and can move the web precisely in equal steps corresponding to the spacing of the labels on the web. Since the forces acting on web 2 during the transporting step are small, the force acting on the deflecting roller 8 is also small. A small leaf spring 18 secured to the lower part of guide means 65, presses the web 1 against the upper part of the same so that the web is slightly braked and is slightly tensioned during passage through the apparatus.
Adjustment roller 67 is mounted on a journal 82 which is guided in a vertical slot 83 of housing wall portion 84, and can be secured in adjusted positions by manually operated screw 85, as best seen in FIG. 3. By adjustment of the position of adjusting roller 67, the length of web 2 between deflector roller 8 and clamping bar 25, can be adjusted for placing the label, approaching deflector roller 8, in the correct position.
The embodiment illustrated in FIGS. 1 to 3, which is advantageously used for labelling oranges, operates as follows:
During the checking, and before the crating of the oranges, each orange 6 is manually pressed into the lined dished holder 5 so that the same moves from the illustrated inoperative position to an operative position about one and a half inches downward to an operative position in which the label 1 on the top face of the elastic support portion 10 is pressed against the surface portion 6a of the orange covering the opening 4 into which support portion 10 enters.
While holding means 5 moves downward, first levers 17 and 77 are turned in counterclockwise direction by bar 15. When the holding means 5 reaches its operative position, actuating means 47,48 engage portion 49 of lever 42 so that the same lifts label-attaching means 3 with supporting portion 3. The camming edges 59 of posts 14 act on lever arms 60 of the guiding device 55 in the transporting direction of web 2.
During the downward movement of the holding means 5, the following operations take place:
a. Due to the counterclockwise turning of the lever 17, a torsion spring 12 on pivot 13 having an arm engaging lever arm 18, is tensioned, and due to the upward movement of stud 19, transporting slide 20 is moved to the left opposite to the transporting direction of web 2.
b. Guide roller 70 is operated under control of the linkage 77,75,72 to move to the right as viewed in the drawing, so that a loop is formed in web 1, and a web portion is unwound from the supply reel, not shown.
c. The lever arms 60 of the guide members 55 are displaced by the camming edges 59 so that the wings of guide members 55 move apart and out of the path of movement of supporting portion 10.
d. The engaging portion 49 of lever 42 is pressed downward by roller 48 on holding means 5 so that roller 51 moves the label-applying means 3 with support portion 8 upward against the action of spring 53 which is tensioned while label 1' is pressed against the surface portion 6a of orange 6 which still is pressed against the lowered holding means 5.
After this short downward movement of holding means 5 during which a label was attached to the orange, the operator takes the orange away from the holding means 5, whereupon the following operations automatically take place:
ev The tensioned spring 46 retracts label-attaching means 3 with elastic supporting portion 10 downward to the initial position shown in FIG. 1. Support lever 42 is clockwise turned until arm 42 abuts stationery stop 45.
1'. At the same time, the tensioned spring 12 turns lever 17in clockwise direction so that bar 15 with post 14 and holding means 5 is raised to the inoperative position of rest shown in FIG. 1. Turning of lever 17 effects downward movement of stud 19 from the upper portion to the lower portion of slot 22 so that transporting slide 20 is moved to the right in the transporting direction in which clamping means 24,25 is effective to press web 2 against the bottom face 26 of top plate 20a so that transporting slide 20 transports web 2 one step whereby a label 1 reaches deflector roller 8.
g. The camming edges 59 move upward and permit lever arms 60 of the guiding members 55 to move toward each other under the action of springs 86 so that guide members 55 assume again the initial position shown in FIG. 3, before the web is transported by transporting slide 20 so that guide members 55 guide the next following label on the portion of the web engaged by deflector roller 8, to the correct position on the top face of supporting portion 10.
h. The upward movement of holding means 5 with bar 15 also effects turning of lever 77 so that guide roller 70 is retracted before the transporting stroke of transporting slide 20 during which the slack of web 1 between the supply reel, not shown, and the entrance opening of guide channel 65 is taken up.
i. During the transporting stroke of transporting slide 20, a label 1 peels off web 2 in the region of the deflector roller 8, engages with its leading edge the slanted guide edges 57 of guide members 55, and drops, with its adhesive face facing upward, onto the top face of the elastic supporting portion 10.
Due to the actions of springs 46 and 12, all parts of the apparatus have returned to the initial position, so that another orange can be manually placed on the dished holder 5.
The above-listed operations take place within between a second and 1 second so that 60 to 100 objects can be provided with labels within 1 minute.
Due to the high speed of the apparatus, the labels separate from the web 2 at high speed in the region of the deflector roller 8. In order to assure that every label 1' is placed in the same position on the top face of supporting portion 10, so that it can be placed on surface portion 6a of the object 6, an abutment bar 90 is provided on the side of supporting portion 10 remote from deflector roller 8. The abutment bar 90 projects about one to three millimeter over the top face of support portion 10 on which the label 1 is deposited. Since support portion 10 and its abutment bar 90 consists of foam rubber or synthetic foam material, abutment bar is pushed outward when support portion 10 is pressed against the object 6. In order to facilitate the movement of abutment bar 90 away from deflector roller 8, while a label 1' is pressed by support portion 10 against the object 6, between support portion 10 with abutment bar 90 and the adjacent housing wall portion 91, a gap is provided which is bridged by a lip 93 of the elastic support portion 10.
The dished holding means 5 is detachably attached to guide posts 14, and can be easily exchanged for a differently shaped holding means, depending on the shape of the objects which are to be labelled.
The embodiment illustrated in FIGS. 4 and 5 can be automatically operated. The holding means 5' which has a cylindrical shape, is located between an upper chute and a lower chute 1000 so that round objects such as oranges and balls roll, and cylindrical objects such as bottles or cans, slide along chute 100 and are received by holding means 5' which is a portion of a lever 104 mounted on a pivot 101 and biased by spring 102 to a normal inoperative position of rest. When an object 6 rests on holding means 5', lever 104 turns against the action of spring 102 so that the button 105 on lever 104 ongages the actuator of a switching device 106 which is connected with an electromagnetic means 110 so that the same upon downward displacement of holding means 5', operates a control member 112 which turns about a pivot 111 to engage with a ring-shaped portion, the object 6, which is stopped on holding means 5', and cannot roll down the chute 100a. Switching device 106 contains another control switch which is normally closed, and opened by member 104,105 to deenergize an electromagnet 115 which normally holds label-attaching means 3 with elastic support portion 10 in a lower inoperative position against the action of the spring 116 which abuts a threaded disc 117 by which the tension of spring 116 can be adjusted.
When electromagnet 115 returns label-attaching means 3,10 with the rod 3a to its initial position, rod 30 operates the actuator of switch 123 by which another electromagnet 120 is energized to attract its armature.
In the inoperative position of the apparatus, electromagnet 11S holds label-attaching means 3 against the action of spring 116 in the lower inoperative position. When the circuit of electromagnet 115 is interrupted by the switching device 106 controlled by an object on holding means electromagnet 115 is deenergized, and spring 116 raises the label-attaching means 3 with the elastic supporting portion and label 1' to a position located in the opening 4 and attaching label 1 to the object 6. The pressure exerted on the object 6 can be adjusted by adjustment of the spring tension by member 117. When holding means 5' is raised by spring 102 after release of object 6 by the control arm 112, electromagnet 115 is energized and lowers the label-attaching means 3 to its normal inoperative position whereby switch 123 is operated to energize electromagnet whose armature operates the pawl 125, pressed by spring 126 against pins 127 of a wheel 121 by which the web 2 is transported about guide rollers and a deflector means 8 which may be a sharp edge or a thin roller. A roller 122 cooperates with transporting wheel 121 so that web 2 is stepwise transported distances corresponding to the spacing of two labels 1 on the same. The web 2 with labels 1 adhering thereto is supplied from a supply reel 131.
A guiding device 155 for guiding the labels separating from the web in the region of the deflector means 8, includes a pair of guide members 55 mounted on pivots 129 for movement toward and away from each other. Links 128 connect guide members 55' with the rod 30 to which the label-attaching means 3 with the elastic supporting portion 10 are secured. When the action of the spring 116 moves the label-attaching means 3 with supporting l0 upward, guiding members 55 move apart and out of the path of movement of supporting portion 10, but in the inoperative low position of the label-attaching means 3, wing portions of guide members 55 are located directly above the top surface of the elastic supporting portion 10 so that the label is reliably guided onto the top face of the supporting portion 10 and cannot again assume a position adhering to the web.
The slanted ring of lever arm 112 not only holds the object 6 on holding means 5' during the attachment of the label, but also exerts a certain pressure on object 6 so that the same cannot be lifted off control means 5' by the pressure of the operative label-attaching means 10, and sufficient pressure is created for attaching the label to the object 6.
It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of label-attaching apparatus differing from the types described above.
While the invention has been illustrated and described as embodied in an apparatus including label-attaching means and object-holding means moving toward each other to a label-attaching position when the holding means for the object is downwardly displaced by manual pressure or the weight of the object, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.
