These prior known devices have been objectionable for one or more of the following reasons: l expensive, (2) damaging to the article, (3) difficult to secure or release, (4) subject to surreptitious removal and insertion onto another article, existence of sharp edges which presented a safety problem, (6) or could not withstand vigorous agitation.
The subject invention relates to a machine which assembles and attaches a tag to an article in such a way that all of the above problems which existed in the prior art have been obviated. The subject machine reliably and inexpensively assembles and attaches a marking tag to an article, and additionally prints indicia on one face of the tag for later identification of the article.
CROSS-REFERENCE TO RELATED APPLICATION This application relates to a machine for assembling and attaching marking tags which are disclosed and claimed in application Ser. No. 629,303 filed on Apr. 7, I967, in the names of James J. Grimm and Robert J. Valihura and entitled Marking Tag and Method of Making an Attaching the Same."
SUMMARY The invention relates to a machine for assembling and securing marking tags to an article. Facilities are provided for positioning a backup layer of sheet material along the edge of the article to be marked with portions of the material lying on each side of the article. The threadlike securing element is then passed through the article and the ends of the securing element are laid parallel to the article on at least one side of the article so that at least one end thereof extends generally toward an edge of the article. Facilities are provided for then superposing and adhering a cover layer of sheet material over the backup layer on each side of the article to enclose and anchor the ends of the securing element therebetween.
In the preferred embodiment of the machine, the threadlike securing element also passes through the backup layer on each side of the article prior to being laid'parallel to the article. The backup and cover layers are preferably cut from a spool having an indeterminate supply thereof so that the feeding and handling of the layers is simplified. Also, it is desirable that the cover layer be provided with a surface having a heat scalable adhesive thereon for adhering the cover and backup layers together to anchor the securing element therebetween. Also, in the preferred form the securing element is a fine wire and the backup layer is made of a wet-strength paper so as to be resistant to deterioration during washing or other similar operations.
The backup layer and the cover layer should be joined along the edge of the article. This can be accomplished by either making the backup layers out of one single piece of material which is folded, or by making the cover layers from one piece of material which is folded over the edge of the article.
The tag assembled and attached by the above described machine has the advantage of simplicity since no pins or staples, etc., are required to secure the tag to the article. There is also the very distinct advantage that the force which is applied to the securing element, i.e., the fine wire, is applied against the tearable backup layer and not the article itself. Therefore, the securing element can be made of a high tensile strength wire to prevent inadvertent release since the release of the tag does not depend upon breakage of the securing element, as is common is previously known devices. The marking tag made by the instant machine also has the advantage that once it is removed from the article it is effectively destroyed and cannot be surreptitiously attached to another article, which is useful the fabric to which it was attached. The marking tag assem bled by the instant machine requires no tool for the removal and is not damaging to the fabric even though a fine wire is used as a securing element. Use of a fine wire also provides the advantage that its insertion through the fabric results in essentially no damage thereto by reason of its small diameter, although it should be clear that this invention is not limited to the use of a fine wire and includes other equivalent securing elements.

DESCRIPTION OF THE INVENTION In FIGS. 1 and 2 there is shown one example of a marking tag which can be assembled and attached to an article by a machine forming the subject of the instant invention. The tag 10 comprises a backup layer 11 which is folded over the edge of an article 12 which is to be tagged. A securing element 13, such as a fine wire, is passed through and folded parallel to the backup layer 11 and the article 12. Subsequently, a cover layer 14 is adhered to the backup layer 11 and the securing element 13 on each side of the article to secure and anchor the securing element 13 therebetween. Preferably, the cover layers 14-14 are provided with a surface of heat scalable adhesive which when heated securely bonds the various elements together.
Removal of the tag is effected, as shown in FIG. 2, by lifting the backup layer 11 and cover layer 14 on one side of the article so that the securing element 13 tears through the backup layer 11 and is separated therefrom. Subsequent pulling on the backup and cover layer will result in the securing element l3 being withdrawn through the article whereupon the backup and cover layer on the other side may be readily separated from the article 12. It is to be understood that the tag assembled and attached by the subject machine can also comprise a pair of backup layers which are positioned on each side of the article and wherein the cover layer is an integral sheet which is folded over the edge of the article. As should be apparent, it is only necessary that the tag 10 be connected over the edge of the article and this can be accomplished by either folding the backup layer 11 over the edge of the'article or by folding the cover layer 14 over the edge of the article.
A very brief description of the overall operation of the machine now follows. Initially, the article 12 is placed on a platform and clamping mechanism 20 (FIG. 3) which is movable in the direction of the arrows. Placing of the garment on the platform 20 initiates one cycle of operation of the machine for assembling and attaching a tag to that article. A discrete piece of backup material 11 is cut and formed by the apparatus designated after which the backup material is rotated and positioned so that the folded edge of the layer extends along the edge of the article 12. As the backup layer is being formed a printing mechanism 200 is actuated to print selected indicia on the backup layer for further identification of the article 12. A securing element applying mechanism 250 then passes the securing element 13 through the backup layer 11 and the article 12 after which the ends of the securing element 13 are bent so that they extend toward the edge of the article 12. The final step in the assembling operation comprises the formation of the covers layers 14-14 by upper and lower cover layer mechanisms designated 350-350. In the preferred embodiment the cover layers 14-14 are adhered to the securing element 13 and the cover layer 11 by a heat sealable adhesive so as to anchor the various elements together.
Platform And Clamping Mechanism 20 Referring now in more detail to the various operating mechanisms and in particular to the platform and clamping mechanism 20 shown in FIGS. 3, 6 and 7, there is provided a platform 21 having an opening 22 for supporting the article 12 during the tag assembling and attaching operation. As the article is positioned on the platform 21, a spring element 23 which projects up into the opening 22 is tripped to actuate one cycle of operation of the machine. Tripping of the spring element 23 causes energization of a solenoid 24 (FIGS. 3 and 28) which through its armature 26 is effective to engage a one way, one revolution spring wound clutch 27 for one cycle of operation. The clutch 27 then connects the power train comprising a continuously operating motor 28, timing belt pulley 29, a timing belt 31, a bushing 32, and a second timing belt pulley 33. The pulley 33 is effective to rotate a cam shaft 34 which when connected with the clutch 27 drives the various cams which will be described in more detail hereinafter. The cam shaft 34 is supported at either end in bearing bracket assemblies 35-35.
Tripping of the spring 23 also energizes a solenoid 36 (FIGS. 3 and 23) which controls the position of a pair of clamp arms 37-37. Energization of the solenoid 36 causes the solenoid armature 38 to advance in the direction of the arrow (FIG. 23) pivoting a lever 39 around a pivot point 40 to tension a spring 41 connected to the ends of a clamp arm support 42. The support 42 is bifurcated to form two clamp arm support levers 43-43 which are pivoted at their end on pins 44-44 supported in the sidewall of the platform 21 (FIGS. 6 and 7).
The clamp arms 37-37 are generally L-shaped and the bottom end of each arm has a pin 46 passing therethrough which is free to slide in a generally vertical slot 47 formed in the side of spring housings 48 48. As the clamp arms 37-37 are lowered to grip an article 12, springs 49-49 are compressed in each of the spring housings 48-48 to provide a resilient, and yet firm, gripping of the article by the arms 37-37. Upon the completion of one cycle of operation and the subsequent deenergization of the solenoid 36, the clamp arms 37-37 are returned to their upper position by a tension spring 51 (FIG. 23) which is connected between the lever 39 and a platform actuating lever 52.
After the article has been clamped on the platform 21 by the clamp arms 37-37, the platform 21 is moved inwardly into alignment with various other mechanisms for assembling the marking tag (FIGS. 6 and 7). This inward o movement is accomplished by the platform actuating lever 52 (FIG. 23) which is biased inwardly by a tension spring 53 connected between the lever 52 and a screw 54 attached to the frame of the machine. At the beginning of a cycle, the platform 21 is positioned in its outward position by a cam 56 which engages the cam follower 57 connected to 'the lever 52. After the commencement of a cycle, the cam 56 is rotated to a low point on the cam permitting the spring 53 to urge the lever 52 in a counterclockwise direction as shown in FIG. 23. The upper part of the lever 52 is provided with a pin 58 which rides in a slot 59in the clamp arm support 42.
The platform 21 is provided with two inwardly directed pins 61-61 (FIG. 6) on each side thereof which are positioned in vertical slots 62-62 in each of the clamp arm support levers 43-43. The rearward and subsequent forward movement of platform 21 and the associated clamp arms 37-37 is guided for horizontal, rectilinear motion by a pair of platform guide brackets (only one shown) 63 having horizontal slots 64 in which the pins 61-61 ride. The rearward portion of the guide brackets 63-63 is rigidly connected to the frame of the machine by screws 66-66, shown in FIG. 3. In its most rearward position, the platform aligns the article 12 with the securing element applying mechanism 250. At a later stage in the cycle, the platform 21 is moved forward to an intermediate position in which is in alignment with the cover layer applying mechanisms 350-350 by another raised portion of the cam 56. In the final stages of the cycle the platform 21 is moved completely forward to its starting position as shown in FIG. 6, by the same cam 56.
Base Tape Forming Apparatus 80 As soon as the spring element 23 is tripped and the cam shaft 34 commences one cycle of rotation, the formation of a discrete strip of folded backup layer is commenced by the mechanism 80. As shown in FIGS. 3, 8 and 9, an indeterminate length of base tape 11 is wound on a spool 81 supported on a shaft 82 positioned on the right side of the machine. The leading end of the backup layer 11 passes through the nip of a feed roller 83 and idler roller 84 for feeding the backup layer through a horizontal guide 86 and into a vertical guide 87 until it strikes a stop 88. The rollers 83 and 84 and the guides 86 and 87 are supported on a bracket 89. The bracket 89 also supports the mechanism designated 91 for folding the backup layer into a generally V-shape between a pair of jaws 92 and 93 supported on a shuttle 94. The jaws 92 and 93 are normally biased in the open position by a torsion spring 96 (FIG. 30a).
The feed roller 83 is supported on a shaft 101 (FIGS. 8 and having a gear 102 positioned on the other end thereof. The gear 102 is in mesh with a gear segment 103 which is pivotally mounted at 104, and has a cam follower 106 on the other end thereof. The cam follower 106 follows the surface of a cam 107 mounted on a cam shaft 108 connected with the cam shaft 34 by a pair of bevel gears 109 and 111 (FIG. 28). The cam shaft 108 is supported at either end in bearing bracket assemblies 112 and 113. Rotation of the cam 107 causes the gear segment 103 to move in a counterclockwise direction as indicated by the arrow in FIG. 11 to rotate the drive wheel 83 a predetermined amount so as to feed a fixed amount of backup layer material from the spool 81 on each cycle of operation. The gear 102 is provided with a one way clutch (not shown) so that the feed roller 83 does not rotate as the gear segment 103 is returned by a tension spring 114 (FIG. 10) secured to the frame of the machine.
After each feeding cycle of the backup layer 11, a stationary blade 121 (FIGS. 8 and 9) and a pivotally mounted blade 122 are effective to cut the base tape leaving a discrete strip of backup layer material extending upwardly in the guide way 87 against the stop 88. The blade 122 is pivoted at 123 (FIG. 14) and is connected at the other end to an armature 124 of a solenoid 126. The solenoid 126 is energized at the proper time by a microswitch 127 FIG. 28) and cam 128 mounted on the cam shaft 34. As should be apparent, the armature 124 is drawn into the solenoid 126 upon energization (FIG. 14) raising the cutting end of the blade 122 so that the backup layer 11 is severed between the blades 121 and 122. Upon deenergization of the solenoid 126, a tension spring 129 returns the cutting end of the blade 122 to its lower position for permitting the leading edge of the now severed backup layer to be fed on the next cycle of operation.
With the base tape so severed and lying in the vertical passageway 87, it is now possible to fold the base tape into a generally V-shaped configuration between the jaws 92 and 93 of the shuttle 94. This is accomplished by urging a former punch 131 (FIG. 8) to the left through an opening 132 in the sidewall of the vertical guide 87 into the open jaws 92 and 93. The former punch 131 has an arcuately shaped leading surface 133 with a pointed rod 134 secured thereto. As the former punch 131 moves to the left (FIG. 8) the backup layer 11 is withdrawn from the upper and lower portions of the vertical guide 87 until it is pressed between the jaws 92 and 93. The backup layer 11 has enough natural resiliency so that when the former punch 131 is retracted the backup layer 11 remains between the jaws 92 and 93.
The former punch 131 is secured to a sliding support 136 having pins 137-137 extending laterally into slots 138 in the bracket 89 for horizontal movement back and forth. The support 136 also includes a drive pin 141 which is positioned between the furcations of a forked lever 142 (FIGS. 8 and 11). The lever 142 is generally U-shaped (FIG. 10,) and is pivoted at points 143-144. Just below the pivot point 144, the lever 142 is connected to a driving lever 146 by a pin 147. The lever 146 is pivoted at 148 and has a cam follower 149 at the other end thereof for following the surface of a cam 150 mounted on the cam shaft 108. The cam 150 and a tension spring (not shown) cause the lever 142 to rock back and forth at the proper time in the assembling sequence to push the former punch 131 into the arms 92 and 93 of the shuttle 94.
After the former punch 131 has placed the backup layer 11 in the jaws 92 and 93 of the shuttle 94, it is desired to rotate the backup layer through and to advance the backuplayer forward a certain distance so that the folded edge of the layer is adjacent to the edge of the article 12. In FIG. 30a the shuttle 94 is shown in its position as it receives the backup layer 11; and in FIG. 30b the shuttle 94 is shown after it has been rotated 90 and advanced forwardly toward the edge of the article 12.
The shuttle 94 includes a shuttle frame 151 having a drive pin 152 (FIG. 8) extending upwardly therefrom. The frame 151 also acts as the support for a pin 153 on which the jaws 92 and 93 are pivotally mounted. The drive pin 152 includes an upwardly extending arm 154 having a cam follower 156 mounted on the end thereof. The cam follower 156 rides in a slot 157 which is cut in a tracking cam 158 secured to the frame of the machine by a bracket 159. The drive pin 152 is carried by the upper fork 161 of a bifurcated shuttle bracket 162. The bracket 162 supports a pin 163 which is movable laterally, forward and backward, by a lever 164 (FIG. 27). The lever 164 (FIG. 25) is pivotally mounted on a pin 166 and is provided with a cam follower 167 which follows the surface of a cam 168 mounted on the cam shaft 34. The cam 168 is shaped to pivot the lever 164 in the clockwise direction (FIG. 27) so as to move the shuttle bracket 162 forward at the proper time in the operational sequence.
The lower portion of the shuttle frame 151 is provided with a shaft 171 (FIG. 8) which rides in a slot 172 (FIGS. 30a and b) provided in a lower tracking plate 173 secured to the frame of the machine. The drive pin 152 rides in a similar slot 172' in an upper tracking plate 173'. The slots 172 and 172' ensure the rectilinear movement of shuttle 94 in both the forward and reverse directions.
The shape of the slot 157 in the tracking cam 158 is such that the cam follower 156 rotates the shuttle 94 through 90 as the shuttle 94 is moved forwardly by the lever 164. This motion is shown most clearly in FIG. 30b.
At this point it is desired to close the jaws 92 and 93 tightly around the backup layer 11 so that the folded edge lies adjacent to the edge of the article 12. The jaws 92 and 93 are provided with bosses 176 and 177, respectively, which are in alignment with corresponding pivotable arms 178 and 179 (FIGS. 6 and 7) provided for closing the jaws 92 and 93. The arms 178 and 179 are pivotally mounted at 181, and are biased together by a tension spring 182. A cam 183 maintains the arms 178 and 179 in their open position until such time as the shuttle 94 is rotated 90 over the edge of the article 12. At this time the jaws are closed by rotation of the cam 183 (FIG. 7) so that the ends of the arms 178 and 179 engage the bosses 176 and 177 to close the jaws.
The rotation of the cam 183 is effected by rotating its support shaft 184 which is connected by an L-shaped lever 186 (FIGS. 3 and 23) to the end of another lever 187. The lever 187 is pivotally mounted at 188 and the other end of the lever is provided with a cam follower 189 which is in engagement with a cam 191 mounted on the cam shaft 34. The cam 191 pivots the lever 187 to rotate the lever 186, which turns the cam 183 approximately 90 to permit the closing of the jaws 178 and 179 by the tension spring 182. Subsequently, the lever 187 is urged in the opposite direction by a tension spring 192 (FIG. 3) to again open the arms 178 and 179 to permit the retraction of the shuttle 94. As the shuttle 94 returns along the tracking cam 158 and the upper and lower tracking plates 172 and 172', the shuttle 94 is rotated 90 in the reverse direction so that it is ready to receive the next backup layer from the forming punch 131 on the following cycle of operation.
When the jaws 92 and 93 are opened, the bosses 176 and 177 engage the shuttle frame 151 to limit their movement. The jaws 92 and 93 can also be provided with tangs 193-193 to hold the backup layer therein as it is rotated.
Referring to FIGS. 32a-d there is shown an ejector mechanism, designated generally 194. The mechanism includes an upstanding ejector bar 195 which is positioned against the folded edge of the backup layer 11 after the jaws 92 and 93 have closed therearound (FIG. 32b). The ejector bar 195 is mounted on a support 196 which is slidable fore and aft with respect to the lower jaw 93. A tension spring 197 connected between an extension of the lower jaw 92 and the support 196 normally urges the support 196 into the rearward position. The forward end of the support 196 includes an upturned hook 198 which engages with a projection 199 on the platform 21 when the jaws 92 and 93 are closed in FIG. 32b. As the platform 21 is moved outwardly (to the left in FIG. 320) by the cam 56, the support 196 and the ejector bar 195 are pulled therewith so as to push the backup layer 11 and the garment 12 therewith. Subsequently, as the jaws 92 and 93 are opened, the hook 198 disengages from the projection 199 permitting the support 196 and the ejector bar 195 to return under the influence of the spring 197.
Printer Mechanism 200 Referring to FIGS. 11-15 there is shown the printing mechanism 200 for placing the desired indicia on the base tape for later identification of the article 12. The printing cycle should take place while the backup layer 11 is positioned in the horizontal guide way 86 and before the feed roller 83 advances the backup layer into the vertical guide way 87.
In FIG. 14 there is shown an opening 201 in the bottom of the horizontal guide way 86 through which a plurality of printing wheels 202-202 can be raised to strike against the bottom surface of the backup layer 11. The printing wheels 202 are provided with any suitable indicia such as numerals or letters which can be aligned with the opening 201 by the manipulation of a plurality of handles 203-203, there being one such handle for each of the printer wheels 202. The handles 203-203 (FIGS. 12 and 13) are each connected to their respective printer wheels 202-202 by bent levers 204-204 having racks 206-206 positioned on the end thereof. The levers are bent in graduated manner to occupy the least amount of space. The racks 206-206 are in mesh with respective gears 207-207 which in turn are in mesh with gears 208-208 one of which is associated with each of the printer wheels 202-202. The printer wheels 202-202 and the gears 208-208 are mounted on a shaft 209 supported on a frame 210. By raising or lowering the levers 203-203 each of the type wheels 202-202 can thereby be set. The wheels are held in this position by spring detents 211-211 (FIG. 13).
In FIG. 11 there are shown two spools 212 and 213 on which is wound a carbon ribbon 214. The ribbon 214 is fed from the spool 212 up along the side of the frame 210 for the printer, across the face of the uppermost portion of the type wheels 202-202 and then down the other side of the frame 210 to be rewound on the spool 213. The carbon ribbon 214 is only shown as it leaves and returns to the spools 212 and 213, and the remainder has not been shown for simplicity.
The printing of the proper indicia against the backup lever 11 is effected by raising the type wheels 202-202 so that the wheels strike the base tape. The force of the printer wheels 202-202 is partially absorbed by a hard rubber pad 221 (FIG.- 14) which is provided in the upperpart of the guide way 86. The type wheels 202 are raised by a generally L-shaped, forked lever 222 which is pivoted on a pin 223. The forks of the lever 222 are positioned under a lifting pin 224 which is connected to the frame 210. An outer frame 226 is provided with slotted guide ways 228-228 on each side which receive pins 229-229 for insuring the vertical movement of the frame 210 and its associated printer wheels 202-202. At the appropriate time in the cycle, a solenoid 231 is energized (FIG. 14) thereby drawing its armature 232 and the associated linkage 233 to the right to cause pivoting of the lever 222 in a clockwise direction. The solenoid 231 is energized by a cam 234 (FIG. 28) which closes a microswitch 236 electrically connected to the solenoid 231. A spring 237 (FIG. 14) is provided between the linkage 233 and the upper portion of the lever 222 to cushion the movement of the relative parts. After the solenoid 231 is deenergized the type wheels 202-202 and the lever 222 return to their original position by gravity.
As shown in FIGS. 11 and 15 the advancement of the carbon ribbon 214 is effected by a ratchet 241 which is mounted on the lower end of the frame 210. A pawl 242 is pivoted at 243 and biased into engagement with the teeth on the ratchet 241 by a spring 244. After each printing cycle as the frame 210 is descending, the pawl 242 engages the ratchet 241 causing it to rotate thereby rotating the spools 212 and 213 to advance the carbon ribbon 214.
Wire Inserting Mechanism 250 After the shuttle 94 and the folded backup layer 11 have been rotated so that the backup layer overlies the edge of the article 12, and after the arms 92 and 93 have been tightly closed around the backup layer, it is desired to pass the securing element 13 through both sides of the backup layer and the article 12 therebetween. Referring to FIGS. 16-18, this is accomplished by passing a hollow needle 251 downwardly through openings 252 and 253 in the jaws of 92 and 93, and severing the wire by cutting mechanism 254 while the leading end of the wire isgripped by a gripping device 256. The cutting mechanism 254, of course, does not operate until the needle 251 has been retracted thereabove.
A spool 261 is mounted for rotation on a shaft 262 positioned inside a cartridge 263. The spool has an indeterminate length of securing element, such as wire, thereon for providing
