Description

Devices for stamping, patterning, etc., on various parts of shoes, made in the form of rollers, provided with signs, patterns, etc. are known on the surface. There are also known devices for sanding, as well as devices for spreading glue and subsequent drying. . P.

These devices have the disadvantage that they cannot sand the soles simultaneously from the upper and lower sides, as well as stamp them, spread them with glue and dry them, as a result of which the soles are usually transferred from one machine to another several times.

The machine described also utilized devices for stamping, sanding, spreading with glue and drying, interconnected by means of a conveyor belt. To eliminate the aforementioned deficiency, the said conveyor is made in the form of an endless belt with sockets for soles and an additional endless belt located inside its branches and having a width And a length less than the main conveyor belt - to allow marks and sanding the sole from the bottom side and then transfer the sole in the drying room

A dryer is used in the machine, in which, in order to lengthen the path of glue-coated soles; Passing through the drying chamber, the latter is made in the form of several disks fixedly mounted on a vertical axis with holes in the shape of a sole and radial blades located above each of the disks, serving to consecutively drop the soles through the holes from one disk to another.

FIG. 1 shows a general view of the machine in perspective; in fig. 2 - part of the machine.

The proposed machine is arranged as follows.

№ 62645

On the rollers / and 2 tension, there is an endless belt 3, provided with nests 4 for the soles throughout. Inside both branches of the belt 3, on rollers 2 and 6 there is an additional endless belt 5, having a width I1 of a length less than the belt 3 and serving as the bottom for the sockets 4 on the belt 5. The speeds of the endless belt 3 and the additional belt 5 are the same.

The soles to be processed fall one by one into slots 4 from shop L, made in the form of several, for example, three, trays 7, obliquely fastened to the frame 9, pivotally mounted on the vertical axis 10. The frame 9 is equipped with rollers 8, installed in a circle 11, rigidly fastened with a table 12.

As spending soles out of the feed tray, turn shop A around 10 axis and install the next tray 7 above the conveyor (belt) 3.

The outsole which has fallen into the slot 4 is fed by the tape 3 and the tape 5 under the pressure roller 13, mounted above the roller 14 for the brand. When the sole passes between the roller 13 and the roller 14, a pressed-in stamp is applied to the lower part of the sole from the bottom. In this case, the tape 5 does not interfere with the roller 14 to perform its work, since this tape is narrower in width than the tape 3, and serves only to support the trace portion of the sole. The soleplate, coming out from under the roller 13, is fed into the skin device B. The latter can consist of two emery and so-called rollers or endless tapes, or from a tape 16 and a roller 15, as approximately indicated in the drawing. In the hide apparatus, the sole is supported by a pressure roller 17, with the upper part of the apparatus processing the entire sole from above, and the lower part - the exact portion from the bottom. The sanded sole is guided to the glue unit C for applying glue to the sole and clearing it off the path, free of dust by means of a chisin, etc., brush (not shown). To save glue roller machine 18 is made in the form of cells.

From the glue apparatus, the outsole is moved by a conveyor (belt) 3 onto a table 19 and. further into the drying chamber D.

To extend the path of glue-coated soles as they pass through the drying chamber, the latter is made in several disks 21 fixedly mounted on a vertical axis 20 with cutouts 22 in the form of soles arranged along a helix and pivotally fixed above each of the disks radial blades 23, employees to consistently drop soles through cutouts from one disc to another. The drying chamber encompasses several disks 21 (approximately 30 pieces), as a result of which it is possible to completely dry the smeared soles when they are transferred from one disk to another with relatively small dimensions of the dryer.

The upper branch of the endless belt 3 lies on the lid of the drying chamber, and the lower one is drained between any two adjacent disks 21 inside the chamber and goes out through the side wall of the chamber.

The operation of the machine is as follows.

The sole blanks are picked up by tape 3 from the next tray 7 of the store one by one and are fed under the pressure roller 13 onto the roller 14 for the brand. Having been stamped, the sole enters the skin device B, from which roller 17 is fed under the cleaning brush. Going out from under the brush, the sole is transferred under the spreading roller 18 of the glue unit C, after which it is guided by tape 5 into the drying chamber.
