BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a device for attaching lightweight, especially steel, provided with protrusions, to sticker labels or shoe insoles, by shifting a sticker or insole with protrusions and folding them on the reverse side thereof. pulley.

The prior art devices are generally designed as disposable presses, where the operator places the parts to be joined directly into the press space and, by pressing the foot pedal, the punch is moved. By pressing the punch, the insole material is pierced by the projections of the crown and the projections are bent and pressed. Since the parts to be joined are inserted directly into the pressing space, this construction requires a number of additional devices to prevent the possibility of injury when performing this operation. These are also important in that the operator controls the switching on and off of the drive mechanism of the device manually or with the foot pedal. In addition to the possibility of accidents occurring in these constructions, they also suffer from low labor productivity due to the insertion and unloading of the brazed parts, the need to coordinate these operations with switching off and on as well as the stroke height of the punch conditioned by insertion and unloading.

Therefore, devices with a cyclically moving punch are designed to increase labor productivity. The linear movement of the punch is derived from a rotating drive by means of a connecting rod or backdrop and the individual duty cycle is not controlled by the operator. Furthermore, the punch stroke is selected as small as possible. This is also made possible by the small pressing surface of the punch, allowing fast insertion and unloading of the parts. The stroke frequency of the punch and the height of the hoist raise considerable demands on the skill of the operator. However, these devices also have the disadvantage that their operation creates a risk of injury.

The above-mentioned disadvantages are overcome by the apparatus according to the invention, characterized in that a first and a second abutment plate are mounted on the base plate, opposite to which the first and second pressure cylinders are arranged and the first pair of V-belts and the second pair of V-belts belts passing through the opening of the foundation thatch.

The technical effect of the invention is to reduce labor intensity, eliminate the risk of injury and to increase labor productivity.

An exemplary embodiment of the device is shown in a perspective view of the attached drawing.

A base plate 1 is fixed to the frame 18 of the device.

Attached to the base plate are first and second abutment plates 2a, 2b, opposite to which first and second pressure cylinders 3a, 3b are arranged, with first and second piston rods 4a, 4b supporting first and second pressure plates 5a, 5b. The first and second pressure rollers 1, 3h are attached to the base plate 1 by means of clips (not shown) and screws. The first and second pressure rollers 3, 3b and the first and second abutment plates 2a, 2b are arranged obliquely so that their position allows the molded parts to be joined without defoaming them. The width of the first and second thrust plates 5a, 5b and the first and second thrust plates 2a, 2b is designed so that they can

An opening 8 is formed in the base plate 2, in this case a cross shape. A first pair of V-belts 8a, 8b and a second pair of V-belts 9a, 9 extend through the opening. A first pair of V-belts 8a, 8b is mounted on a first upper pulley 6 rotatably mounted in a first support 14 and a first lower pulley 2 rotatably mounted in a first bracket 12. The first support 14 is displaceably provided on the first bracket 12 and its the adjustment allows to tension the first pair 8a,

8b V-belts. A second pair of V-belts 9a, 9b is mounted on a second upper pulley 10 rotatably mounted in a second support 15, ^{and a} second lower pulley 11 mounted on a drive shaft 25 rotatably provided in a second bracket 13. A toothed gear is further provided on the drive shaft 25. a wheel 24 cooperating with a pastor 16 mounted on the drive shaft 17 of the hydromotor 19. Between the first pair of V-belts 8a, 8b and the second pair of V-belts 9a, 9b is provided a limit switch on the second bracket 13, not shown in the drawing. The first and second brackets 12 and 13 are fastened by screws (not shown), the first bracket 12 being mounted lower than the second bracket 13 so that the first pair 8a, 8b of the V-belts is longitudinally offset relative to the second pair of V-belts 9a, 9b. The longitudinal displacement allows transverse displacement of the first lower and upper pulleys 2 and 6 relative to the second lower and upper pulleys 21 and 10, so that the first and second pairs 8a, 8b and 9 'of the belt belts are transversely displaced relative to each other. The first upper pulley 6 stretches the type of the V-belt pair 9a, 9b o

and the second lower pulley 11 tensiones the first pair of V-belts 8a, 8b. The base plate 2 ^{with the} working mechanisms is covered by a cover 23 in which a similar cross hole is formed as the opening 4 in the base plate 2. »

-4232 062 The workspace is inaccessible to the operator.

the operation of the device is as follows. The drive from the drive shaft 17 of the hydraulic motor 19 is transmitted to the driven shaft 25 via the pastoic 16 and the gear 24. The second lower pulley 11 drives the types of V-belts, 2a, 9b, which drive the first pair 8a, 8b of the V-belts. After the manual insertion of the label 21 with the enclosed jewel 22 between the thread and the pair, the pair 8a, 8b and 2a> 9b of the V-belts is carried by them into the work space. Impact of the label 21 on the limit switch (not shown) stops the hydraulic motor 19 and thus the second lower pulley 11. At the same time, the first and second pressure cylinders 2a, 22 'are actuated, which press the labels 21 s with the first and second pressure plates 5a, 5b. by a ring 22 to the first and second opaque plates 2a, 2, fr. The tabs 22 (not shown) will pierce the labels 21 and will bend on its side, whereby the tab 22 is attached to the labels 21.

After releasing the pressure of the first and second pressure cylinders 3a,

3b, and the engagement of the hydraulic motor 19, the sticker 21 with the collar 22 attached is carried to the cartridge 20. During this cycle, further joined parts may be inserted between the first and second pairs of V-belts 8a, 8b and 9a, 9b.

The figure shows the vertical arrangement of the device. However, this can be arranged horizontally without changing the nature of the invention, with the connection of a device for carrying out the subsequent manufacturing operation.
