Device sum attaching labels to fabrics and the like.

by means of trailers

The invention relates to a device for attaching Labels on fabrics and the like by means of tags that have a thread-like section with an adjoining crosspiece, wherein the device, preferably designed as a needle, tubular ejection part for the cross pieces with a Slot for the passage of the subsequent thread-shaped Sections as well as a plunger entering the bore of the ejection part, which is connected to the cross piece of the straight to be attached trailer comes into engagement at the end.

Such a device goes, for example, from the USA patent 2,069,878. With this awl-shaped device, the cross pieces of the trailer have to be drilled individually by hand of the needle-shaped ejection part, whereupon through the one arranged on the side of the device Pins connected to the slide button *! Can be ejected.

From the USA patent 2 952 851 a similarly designed device emerges, but with a laterally attached

209815/1066

set magazine for receiving the cross pieces is provided with a large number of tags. The cross pieces are by means of a spring-loaded slide automatically tracked from the magazine after the plunger drilled the hole of the needle-shaped Has left the discharge part following a working stroke.

According to US Pat. No. 3,103,666, a connecting strip is used contiguous tags for use integral with the connector strip and at the other end of the heads located in the thread-like section are molded from plastic such as nylon or polyvinyl chloride. These related Trailers are fed into the device from the side by means of a toothed feed wheel, whereupon they are separated from the connecting strip by a knife before being introduced into the bore of the needle-shaped ejection textile will. The ram, which is also present here, is operated by a handle like the knife and the pre-lifting wheel, which is hinged like a pincer grip on the device shaft.

U.S. Patent 3,470,834 again discloses one Ahlenförraiges device, with the similarly designed and connected tag for fastening buttons in the fabric can be introduced. This device, too, has a toothed feed wheel which, however, is turned by hand must become. Meanwhile, a special knife for cutting off the individual trailers is saved by removing the rear The end of the needle-shaped ejection part has a cutting edge which cooperates with the ram. The plunger itself stands telescopically over the device shaft sliding handle in connection.

With all of these devices there is a need to replace the ejection part before time, for example when the needle tip and / or the * cutting edge is blunted. A similar device in which. the ejection part is not designed as a needle, but instead the cross pieces of the trailer are pointed on one side

the USA patent specification 3 185 367. Here, too, it would be desirable to be able to easily replace the ejection part if this, as in the previous case, is provided with a cutting edge were. In reality, however, the latter device has a special cutting device by between two Feed wheels a co-rotatable cutting plate is arranged, which interacts with the ram.

The object of the invention is to make a device of the type mentioned above simpler and more user-friendly, in that, above all, the ejection part is made easy to use and interchangeable. This discharge part is known in the art Cases either clamped in a relatively complicated manner, held in a press fit within a housing bore or - in Case of the rear cutting edge - inserted from the rear into the housing so that it can be replaced either requires special tools or dismantling of the device.

The object set is achieved according to the invention by that the rear portion of the ejection part is designed as a rack, which is relatively loose from a corresponding Bore of the device housing is added and meshes with a toothed segment that can be rotated by hand after unlocking.

In addition, the invention provides, when using related Trailer also to make use of a feed wheel and a cutting edge located on the ejection part. and to combine the drive of the feed wheel with that of the ram. These and other details are equally suitable are to create a device that is as usable as possible with a simple structure, go from the following description of a Embodiment based on the figures.

In the illustrated device 20, trailers such as those in FIG

209815/1066

Fig. 1 illustrated trailer 21 for application, the first are combined to form a tag strip 22. Fig. 1 shows a typical application for how labels 23 are attached to a fabric 24 with the aid of tags 21. Everyone The trailer 21 has a cross piece 25 and a head piece 26 connected by a thread-like connecting piece 27. ·

The tag strip 22 is preferably made of plastic, such as. B. nylon or polyvinyl chloride, and can be in one piece be shaped in that each tag 21 is connected directly to a connecting strip 22 'via an intermediate piece 28 (Figures 5, 10, 11 and 12).

As can be seen especially in FIGS. 2, 3 and 4, the device 20 has a housing which is composed of the housing body 29 and cover 30. On the inside of the housing body 29 pins 31, 32 and 33 are formed. In addition, it has a pistol grip-like grip part 34 (FIG. 3). In this a trigger lever 35 is mounted by means of the pin 31, which is to be gripped with the fingers of the holding hand. If pressure is exerted on it, the trigger lever 35 pivots counterclockwise according to FIG. 3, whereby it also pivots an intermediate lever 36 mounted on the pin in the housing in a counterclockwise direction. The trigger lever 35 consists of a one-piece molded part with two spaced apart side walls 37 and 38 which are connected to one another by an end wall 39. This end wall is adjoined on the inside by a web 40 which likewise connects the two side walls 37 and 38 to one another and against which the intermediate lever 36 abuts. One end of a tension spring 41 is ^{suspended from a pin 29 f formed} on the inside of the housing body 29 and engages with its other end through a hole 42 in the intermediate lever 36 in order to pivot it clockwise according to FIG. 3 and always into his To lead the starting position, he also brings the trigger lever 35 into its starting position via the web 40. Projections 43 on the side walls 37 and 38 come to the housing body 29 at 44 to the plant to the

Movement of the two levers 35 and 36 into their starting position, d. H. clockwise to limit.

The case body 29 has a side wall 45 and a End wall 46 (Fig. 2). On the side wall 45 are except the. Pin 29 ', 31, 32 and 33 on the inside two to each other molded parallel, stepped guides 47 and 48 (Fig. 3). Apart from their management function, these tours serve to reinforce the housing body 29. In the guide 47, a guide stone 49 can be seen, which is only in is movable in two opposite directions. Step sections 50 and 51 of the guide block 49 (Fig. 17) are with correspondingly stepped sections of the guide 47 in Intervention. Furthermore, the guide block 49 has a section 52 of smaller diameter, and the sections 50, '51 and 52 are arranged coaxially to a central bore 53 which has a bent section 56 of the plunger 55 takes up, which consists of steel wire for example. Section 52 engages in an elongated hole 54 of the lever 36. Further If the plunger 55 is guided by a groove 57 in a guide pin 58 (Figures 3 and 6), which is also on the side wall 45 of the housing body 29 is formed, as well as from äner Groove 59 in a guide 60 on the cover 30 of the housing. The cover 30 is further reinforced by the guide 60. The guide 60 has a cutout 61 into which the guide pin 58 enters. In this way, the plunger 55 is in the Grooves 57 and 59 of the guides 58 and 60 included so that it can only move back and forth.

The guide 48 receives an elongated slide 62 (FIGS. 2 and 4) which has a wider and a narrower profile section 63 and 64, respectively. On the slide 62 is a. Shaped pin 65, which is received by an elongated hole 66 of the intermediate lever 36. As can be seen from FIG. 3, the elongated holes 54 and 86 are aligned with one another and with the pin 32 about which the intermediate lever can be pivoted.

203815/1066

_ ₇ _ 2U8A18

The slide 62 itself has an elongated hole 67 (Figures 3, 10 and 11), which extends over a substantial part of its Length and parallel to the guide 48 extends. A pawl 68 which engages a ratchet wheel 70 with a tooth 69, is received by part of the guide 48 between the slide 62 and the side wall 45. A spring finger 71 is the pawl 68 is pressed against one side of the guide 48 and against the ratchet wheel 70. In the guide 48 she is with such Play stored that the tooth 69 on the return stroke can slide over such of the ratchet wheel 70 to with the next Tooth gap to come to the intervention. The claw 68 engages with an integrally formed pin 72 in the elongated hole 67 of the slide 62.

The ratchet wheel 70 is provided with a feed wheel 73 as well as a hub part 74 lying therebetween is formed as a one-piece molded part. In this way, any relative movement is between the ratchet wheel 70 and the feed wheel 73 switched off. Both wheels are arranged coaxially to a central bore 75, with which they are rotatably mounted on the pin 33 (Fig. 3).

As can be seen in Figures 3, 8, 13 and 14, is a tubular ejection part 76 inserted into the housing body 29 at the front. This ejection part 76 ends in a needle point 77 and has a through hole 78. The needle tip 77 is located on a needle section 79 of relatively small diameter, which merges at the rear into a widened section 80 (FIGS. 8 and 9). The bore 78 ends on the one hand behind the needle point 77 and on the other hand at a sharp cutting edge 81 in the enlarged section 80. The inside diameter the bore 78 is large enough to allow the crosspiece of a trailer 21 (see FIG. 14) to pass through unimpeded allow. A longitudinal slot 82 (Figures 3 and 8) communicates with bore 78 (Figure 7) and is wide enough the thread-like section adjoining the crosspiece 27 to let pass while the crosspiece itself the bore 78 passes. At the extended section

-8th-

209815/1066

of the ejection part 76 is a flat 83 (Figures 8 and 9) is present, which is substantially parallel to the central plane of the Slot 82 runs. Another slot, 84 (Fig. 7), is also provided in the enlarged portion 80 of the ejector member communicates with the '78 hole and is as wide as this. At one end on the cutting edge 81 (Fig..8) he is open while its other end 85 is closed. The slot 84 closes with the flat 83 with a slight Radius 86 (FIG. 7) to allow easy entry of the cross pieces 25 into the bore 78 through this slot.

As shown in Figures 2 and 5, in the housing body 29 for receiving the tag strip 22 is a cross-shaped Slot 87 is formed. This slot has zones which receive the individual profile sections of the strip 22. So the zone 88 takes the connecting strip 22 * and the intermediate pieces 28, the zone 90 about one half of the crosspieces 25, the zone 91 the other half and the zone 92 the beginning of the thread-like sections 27.

Every time the trigger 35 is fully pulled and is then released, the feed wheel 73, which engages between the individual intermediate pieces 28, guides the trailer strip 22 by one division, i.e. H. from the middle of the cross piece to the middle of the cross-P piece, straight ahead.

Since the cutting edge 81 is located at the end of the bore 78 within the widened section 80 of the ejection part, that cross piece 25 which is currently in the bore is separated from its intermediate piece 28 when the plunger 55 hits, which remains on the connecting strip 22 ' (Figures 2, 10, 11 and 12).

The tooth pitch of the feed wheel 73 corresponds to the pitch of the spacers 28 so that there is a soft engagement to ensure that the tag strip 22

209815/1066

2H8418

just continued by one division. A spring finger 93 (Fig. 3), which appears broken off in Figures 10 and 11, comes with the teeth of the feed wheel 73 into engagement in order to this V / eise a detent to prevent any return stroke create. The spring fingers 71 and 93 are connected via a common fastening section 94, the ends of which are recesses 95 and 96 of the housing body 29 are held. With the fastening section 94, the spring fingers 71 and 93 stamped out of a piece of elastic material.

As shown above all in FIGS. 7, 8 and 9, a stop shoulder 97 (FIG. 9) is formed on the widened section 80 of the ejection part 76 in connection with the flat 03, which abuts against a counter shoulder 98 within the bore 99, of which the portion 80 is received. This limits the distance that the ejector 76 can be inserted into the bore 99. A toothed rack 100 is formed on the widened section 80 on the other side of the flat 83. According to FIG. 8, the section 80 is completely inserted into the bore 99. As can be seen, the rack 100 is in engagement with the teeth of a tooth segment 101. The toothed segment 101 has a hexagonal central bore with which it is arranged non-rotatably on a hexagonal section of a shaft 103. With circular cylindrical sections 104 and 105 adjoining the hexagonal section 102 on both sides, the shaft 103 is rotatably supported in corresponding bores in the housing body 29 and the cover 30. In the circular cylindrical section 105, an annular groove 106 is formed immediately next to the toothed segment 101, as can best be seen in FIG. 15. The sector gear 101 is provided frontally with three all around evenly distributed projections 107 (Fig. 16) which engage elastically in the annular groove 106 to the toothed segment against axial movement on the shaft set 103 'from rotating relative to the shaft, the sector gear through the hexagonal section 102 of the shaft prevented in connection with its hexagonal central bore. A compression spring 106 '(Fig. 7), which surrounds the cylindrical section 104 of the shaft 103, lies on the one hand on the housing

209815/1066

body 29 and on the other hand to the toothed segment 101 to a locking projection 107 'of a rotary knob 108 on the shaft in to press a corresponding recess 109 in the housing body 29.

To remove the ejector 76 from the housing, push the protruding end of the cylindrical portion 105, whereby the locking projection 107 * against the force of the Spring 106 * is led out of recess 109. In this position, the shaft 103 can be connected to the button 103 according to FIG. 8 be rotated counterclockwise, whereby the toothed segment 101 pushes the ejection part 76 out of the bore 99. so the ejector can easily be replaced. While the parts are in the position shown in FIG. 9, the locking projection is located 107 »of the button on the flank of the housing body 29.

A new ejection part 76 with a sharp needle point is now intended and cutting edge are inserted into the bore 99, it is first pushed into this until its Rack 100 comes into engagement with toothed segment 101. The ejection part can now be moved to the position by turning the knob 108 8 are inserted into the bore 99 up to the stop.

In the case shown, the tooth segment 101 has five teeth that spread over an angle of significantly less than 360 °. In the position according to FIG. 8, a last tooth 101 rests one side against a stop 110, while in the position according to FIG. 9 the other last tooth 101 ″ on the other side of the stop 110 rests. In this way, the rotational movement of the tooth segment 101 is limited.

A retaining pin 111 is also attached to the cover 30 (Figures 2 and 6), which ends in two separate stop surfaces 112. If the cover 30 is placed on the housing body 29, the stop surfaces 112 are on both sides of the elongated hole 67 on the slide 62, while the space between the stop surfaces | the pin 72 passes through

209815/1066

Furthermore, pins 113 (Fig. 2) are formed on the cover 30, the full in corresponding recesses 113 ', 31 * and 32 'Find recording. The pins 113 together with the pins 29 ', 31' and 32 'form strong, rigid holding means for the Spring 41, the trigger lever 35 and the intermediate lever 36. The plastic material from which the cover 30 is molded allows a locking connection with the housing body 29 by means of molded locking projections 114, which are also molded behind Projections 115 of the latter rush.

With the exception of the springs 41 and 106 ', the piece with the With spring fingers 71 and 93, the ejection part 76 and the plunger 55, the device 20 is made entirely of malleable plastic. About that in addition, it has very few parts, making it ideal for mass production at low cost.

In the use of the device, if a label 23 on any pierceable material, such as B. the tissue 24, is to be attached, the needle is in the desired location pierced through the label and then through the material. When the trigger lever 35 is pushed back, the thus engaged intermediate lever 36 pivoted counterclockwise against the force of the spring 41 according to FIG. 3. at this movement of the lever 36, the plunger 55 is displaced to the left according to FIG. 3. After the ram hits the The end of the cross piece 25 of a trailer, which is currently in the bore 73, is by means of the cutting edge 81 of the ejection part the cross piece separated from the subsequent intermediate piece and finally through the bore 78 and an enlarged Opening 78 pushed out at its end beyond the pierced tissue (FIGS. 10 and 14). While the cross piece 25 the Bore 78 happens, the subsequent thread-like portion 27 passes through the slot 82 (Fig. 7) until the trailer has reached the position shown in FIG.

209815/1066

Meanwhile, the intermediate lever 36 has guided the slide 62 into a position in which the pin 72, at the end of the Arrived elongated hole 67, the claw 68 moved over the next tooth of the ratchet wheel 70 according to FIG. 10 to the left Has. If the trigger lever 35 is now released, the spring 41 guides the intermediate lever 36 with the trigger lever into the starting position (Fig. 3) back, whereby the plunger 55 returns to its starting position. Just before the lever 36 reaches its starting position reached, the pin 72 of the claw comes to rest at the other end of the elongated hole 67 (FIG. 11), so that the ratchet wheel 70 from now on carried along with the feed wheel 73 and in a counterclockwise direction is rotated. So that the tag strip 22 is advanced by one pitch, so that the cross piece 25 of the next Trailer comes to rest in the hole 78. That is, that part of the crosspiece that is from the zone 90 of the Kreuzsclilitzes 87 is received, enters through the slot 84 (Fig. 7) in the bore 78 of the ejection member.
