Focht, Dayton, Ohio, assignor to The Hobart Manufacturing Company, Troy, Ohio, a corporation of Ohio Filed Feb. 23, 1953, Ser. No. 19,314 4 Claims. (Cl. 226-53) This invention relates generally to apparatus and methods of effecting accurately controlled feeding of a strip of tickets, labels or the like.
The invention has particular relation to apparatus and methods for intermittently advancing, printing and issuing successive tickets, labels or the like from a strip thereof, and it has special application to such apparatus and methods for handling such strips wherein the individual tickets or like sections of the strip are specifically identified on the strip, as by individual design or preliminary printing, to such extent that the final printing thereon in conjunction with issuance thereof must be accurately registered lengthwise or" the strip.
As an illustrative example of the subject matter of the invention, it is explained hereinafter in connection with a scale which is constructed as a complete unit to weigh food products or other commodities and to issue a printed ticket bearing thereon both the weight and the computed value of the weighed material. Scales of this character are particularly useful for food markets of the self-service type selling commodities such as meat in prepackaged form, with the printed label being attached to the package before the package is placed in the display case ready for selection by the customer. It is valuable from the standpoint of advertising, for example, that the printed ticket or label received by the customer clearly identify the store, and this value is further enhanced by the use of attractive designs and/or color combinations on the printed ticket. it is ditticult, however, as a practical matter to do all the printing necessary to this end Within the scale or other issuing unit.
The advantages outlined above can be achieved without the attendant practical dificulties if the ticket is preprinted with the desired advertising and/or design material so that the scale is required only to print the results of the weighing operation and other variable data such as the identity and/or grade of the particular commodity. This in turn, however, introduces relatively strict requirements of accuracy for the feeding of the ticket strip, since the data printed by the scale should register properly with respect to the printed material. Thus unless feeding of the ticket strip is in accurately controlled increments of one ticket at a tirne, the successive ticket sections of the strip may progressively get out of register with the printing station of the scale, with resulting possible spoilage of tickets.
In the Allen Patent No. 2,824,736, issued February 25, 1958 to the assignee of this application there is described an arran ement for accuratel feedin a ticketstrip in increments of a single ticket wherein the feeding mechanism is operated in one direction to advance the strip a distance slightly greater than a single ticket length, and then is operated in the reverse direction to retract the strip and to establish accurate registration and indexing of the ticket with a relatively fixed stop receivable within successive perforations in the strip. Similarly accurate registration of each ticket is achieved in accordance with the present invention by causing the ticket to be retracted by a movable strip engaging member which operates upon the completion of the forward drive and which also serves as the stop for indexing the strip preparatory to cutting.
t is a primary object of the invention to provide new and. improved apparatusfor feeding a strip composed of.
3,021,988 Patented. Feb. 2O,v 19.62
multiple tickets, labels or like sections which will effect the feeding of the strip in accurately controlled increments such that only a predetermined precise length of the strip will be advanced during each feeding cycle, and which apparatus will at the same time be comparatively simple and compact in construction and will possess minimum requirements from the standpoint of maintenance.
An additional object of this invention is to provide a strip feeding apparatus as outlined above which includes mechanism for advancing a ticket strip in a single cycle of operation slightly further than the length of an individual ticket and for engaging the strip at individual perforations to move the strip through such engagement in a reverse direction to an indexed position corresponding to a whole multiple of a full ticket length.
it is also an object of the invention to provide strip feeding apparatus as outlined above which is adapted for incorporation in existing ticket printing machines for handling unprinted ticket strips and which will enable the converted machine to handle a preprinted ticket strip tuid to print and to issue successive tickets therefrom on which additional data is printed in the machine in consistently accurate registered relation with the preprinted portions of the ticket.
Other objects of the invention will be apparent from the following description, the accompanying drawings and the appended claims.
In the drawings:
FIG. 1 is a somewhat diagrammatic view illustrating strip feeding, printing and issuing apparatus constructed in accordance with the invention;
IG. 2 is a somewhat diagrammatic view illustrating an example of a single ticket of the type issued -by the ap paratus of FIG. 1;
' FIG. 3 is a view similar to FIG. 2 showing a fragment of the strip of tickets handled by the apparatus of FIG. 1;
FIG. 4 is a fragmentary view of the upperside of a portion of the indexing mechanism of FIG. 1;
FIG. 5 is a fragment of FIG. 1 showing a-moved position of the indexing mechanism;
FIG. 6 is an enlarged fragmentof FIG. 1 showing the advanced position of the strip prior to indexing and' its relation to the indexing head; and
FIG. 7 is a view of the parts of FIG. 6 showing the moved position of the strip into the indexed position.
Referring to the drawing, which illustrates preferred embodiments of the invention, FIG. 2 shows an illustrative example of a single ticket 10 of the type issued by a scale operating in conjunction with the apparatus of the invention for use by a food market in prepackaging meat. As shown, such ticket may be preprinted to carry the name of the store and a variety of other copy selected in accordance with individual preference. Such preprinted material may appear on each successive ticket portion of an elongated strip 11 of blank tickets as shown in FIG. 3. Each ticket portion 12 on the strip may also be provided with a decorative border 13 of a contrasting color or other design, and the preprinting of the strip may also include the name of the store as indicated at 14 as well as the headings for the weight, price and price-per-pound as shown at 15 in FIG. 2.
Witheach ticket portion 12 thus specifically designated on the strip 11 by the preprinted matter, the ticket issuing portion of the scale assembly is required only to print the identity and grade of the commodity as indicated at 26 and 17 in FIG. 2, together with its weight, price-perpound and computed value. On the other hand, with the major part or" the ticket or label preprinted, feeding of the ticket strip must be accurately controlled in order to assure that the final printing in conjunction with the weighing operation will always beaccurately in register with the spaces intended therefor for the successive inpivotally mounted at dividual tickets. The present invention is especially directed to the accomplishment of this'object.
In accordance with the invention, the ticket strip 11 is provided with a series ofperforations or slots which are located in accurately spaced relation lengthwise of the strip, centrally in the margin between adjacent tickets so that the spacing of each adjacent pair of perforations is accurately equal to the desired dimension of the individual ticket 10 lengthwise of the strip. While the configuration of the individual perforations is primarily a matter of choice, they are shown as rectangular slots each having a forward leading edge 21 and a trailing edge 22, and the individual tickets 10 are'indicated as severed along approximately the middle of these. slots.
The mechanism for feeding andprinting the tickets is shown in FIG. 1 as including a supply roll 25 from which the ticket strip 11 is fed through an elongated chute having slots 31 and 32 in the upper and lower walls thereof through which the strip is engaged for feed ing by a rubber pressure roll 33 in cooperation with a driven cylinder 34 operated intermittently by the main drive which is indicated diagrammatically at 35 and which may, for example, be of the construction shown in Robertson Patent No. 2,056,486, issued October 6,
1936 and in the Goodbar et al. Patent No. 2,889,769, issued June 19, 1959. The nature of the drive 35 is not critical for the purpoes of the invention and operates to provide one full revolution of the cylinder 34 for each feeding cycle of the apparatus. The feeding action of the cylinder 34, however, occupies less than the full revolution and is controlled by knurled or otherwise raised or roughened feed rail portions 36 of the cylinder 34 which are coordinated with the actual length of each ticket portion 12 to provide a feeding stroke for the strip which is greater than the length of a single ticket.
Thus each time the drive 35 is operated, the cylinder 34 will make one complete revolution, and during the interval while its feed rail portions 36 are in pressure engagementjwith the strip 11 and roll 33, the strip will be fed forward, but during the remainder of the revolution of the cylinder 34, there Will be no forward feeding of the strip. It is understood that the cylinder 34 may also have incorporated therein type wheels or an electro, which may be employed to print some of the desired data on each ticket 10, such particularly as the grade of the commodity and/or other identifying data of the type indicated at 17 in FIG. 2. A detailed disclosure of suitable such printing mechanism is found in Robertson Patent No. 1,816,263, issued July 28, 1931, and its cooperating inking roller is shown at 38.
, From the feeding chute 30 the ticket strip 11 passes to the knife chute 40 which is carried by a knife 41 42 for cooperative movement towards and away from a stationary cutoff bar 44 to shear successive tickets from the strip. Beyond the knife chute 40 is a further guide chute 45 which is slotted at 46 to provide a printing station receiving cooperating printing wheels 50 and an impression hammer 51 for printing the weight, price and price-per-pound of the weighed commodity on successive ticket blanks 12, the printing ribbon for the impression hammer 51 being indicated fragmentarily at 52. Movement of the printed ticket beyond the printing station is under the control of a pair of ejector wheels 55 operating in additional slots'in the chute 45 beyond the printing station. FIG. 1 also shows a'key located beyond the ejector wheels 55 for printing the commodity designation 16 on the ticket through a slot 61 in the underside of the chute 45. The mechanism by which these several parts are set and operated may be automatically controlled by the weighing action of the scale or may be of any convenient manually actuated character and forms no part of the present invention. A suitable such mechanism for the ejector rolls, knife and other associated parts is shown, for example, in the above noted Robeitson and Goodbar et a1. patents.
In accordance with the present invention, accurate registration of each successive ticket 10 with relation to the printing station and the cut-off bar 44 is established by control of the feeding of the strip 11 in such manner that during each cycle of the roll 33 and cylinder 34, the strip is first fed forward a distance slightly greater than the length of a single ticket blank 12. Then during the remainder of the cycle, the strip 11 is moved in the reverse direction by a movable stop mechanism which engages one of the slots 2% and moves therewith to an indexed position accurately correlated with the length of one or more complete ticket blanks such that the shearing action by the knife 41 will take place at the desired point between the leading pair of tickets on the strip.
The movable stop mechanism includes an arm from which a finger 71 depends adjacent the path of movement of the strip 11 and carries a strip-engaging book 72 on the extended end thereof. The finger 71 includes a slotted portion 73 which is adjustably secured to the arm 70 by a pair of screws 74. The finger 71 is arranged to move from a dwell position shown in full lines in FIG. 6, in a direction parallel to the line of movement of the strip 11 subsequent to completion of the advance feeding of the cylinder 34. During this movement, the slot-engaging hook 72 is arranged to engage the adjacent slot 20 of the strip 11 at its trailing edge 21 through an access opening 75 in the chute 30 to cause the strip 11 to move in a reverse direction into the predetermined indexed cutting position.
Means for effecting such movement of the arm 70 and finger 71 includes a cam 85 connected to the drive 35 so as to complete revolution during each cycle of operation. The rotation of the cam 30 is correlated with the rotation of the strip drive cylinder 34 to provide reverse movement of the strip 11 by the hook 72 at the conclusion of the forward drive effected by the cylinder 34-. A cam follower crank 81 is pivoted at 82 and includes a follower roller 83 arranged to ride on the surface of the cam 80. The roller 83 is held in contact with the cam by a tension spring 85 secured to an extended arm portion 36 of the follower 81.
A draw link is connected for pivotal movement on the cam 3h at a pivot 91 and further includes an extending pin 92 forming a pivotal connection 93 with the arm 70. Means connecting the link 96 for movement in response to the movement of the follower 81 includes a line view in FIG; 7. The indexed position is determined by the profile of the lobe 96 and by the adjusted position of the finger 71 on the arm 70, and is therefore the same for each cycle of operation.
Upon the initial reverse movement of the arm 70, the finger 71 is guided downwardly into contact with the strip 11 from its dwell position to a position in engagement with the upper surface of the strip ahead of the advanced position of the adjacent slot 20, as shown in full lines in FIG. 6. The downward movement of the hook 72 is effected by a torsion' spring 103 on the pin 92, and the arm 70is guided during initial movement by the cgaction of a cam surface 104 on the underside of the arm with a cooperating guide collar 105. The collar 105 is mounted on a transverse rod 106 which is, in turn, supported above the chute 30 by a pair of upwardly extending support arms 107. Continued rearward movement of the arm 70 by means of the pin 94 and slot carries the hook 72 along the upper surface of the strip 11 until it drops. through the, adjacentperforation 20 as shown in FIG. 7. The cam surface 164 and the collar -105 are therefore guide means which provide for the movement of the hook 72 from its dwell position onto the upper surface of the strip 11 ahead of the advanced position of the adjacent perforation.
As is most clearly shown in FIGS. 6 and 7, a portion of the chute 36 is depressed at 110 to provide a space 111 below the strip 11 into which the hook 72 may project when in engagement with the slot 20. The depressed portion 119 of the chute 30 also provides a support or bearing surface for the hook 72 when in engagement with the slot 20 of the strip.
The rotation of the cam 80 and the relation of the lobe 96 of the follower 83 is such that the hook 72 draws the strip 11 into the indexed position and remains in engagement with the perforation 20 during the cutting operation. The parts are now in the position as shown in FIG. corresponding to the indexed position of the strip 11. At the conclusion of the cutting operation by the knife 41, the continual rotation of the cam 80 by the drive 35 returns the finger 71 to its dwell position as shown in FIG. 1 preparatory to the initiation of a new cycle of operation.
It is therefore seen that this invention provides a positive mechanism for accurately positioning successive ticket portions of a strip of tickets for printing and cutting, as desired. It is apparent that the particular configuration of the individual perforations 28 is not controlling provided each perforation has a trailing edge portion 22 located in the same spaced relation with the printed material on the associated ticket portion of the continuous strip. Accordingly, the term perforation as used herein is not limited to any particular configuration or size and include slots and other shapes which will provide such desired relationship between the leading edges of the successive perforations and the printed matter appearing on the successive ticket portions of the strip.
While the form of apparatus herein described constitutes a preferred embodiment of the invention, it is to be understood that the invention is not limited to this precise form of apparatus, and that changes may be made therein without departing from the scope of the invention which is defined in the appended claims.
