Description

The number And factory mark on rubber-coated shoes are usually affixed to the inside of the shoe on a textile insole, which, due to the blurring of the image, and sometimes the loss of the insole, created a number of inconveniences.

The object of the invention is an automatically operating machine for the shoe industry, with the help of which it would be possible to make an impression with the indicated designations on a rubber sole in such a way that it can be seen even after noKipacKH sole.

For this, in the machine, according to the present, it is used, known for hot stamping on rubber soles, is used for the multifaceted drum with stamps, heated by electric and heaters, & also a sliding gate for pushing the soles out of the bunker and feeding them under the drum.

However, the proposed machine differs from the known devices of this kind in that, for correct installation, under the bunker of the soles a special device made of COLLARS and guide rails is used. One of the squares is made movable, due to which the possibility of feeding the soles of different lengths is carried out, and the guide strips are arranged so that they can be moved, placing them along the shirk of the soles.

In addition, the machine used the scale and pointer, with which the bunker can be set to the size of the soles.

In FIG. 1 shows a general view of the car; FIG. 2 - her plan view; FIG. 3 is a side view of the machine along the arrow A in FIG. one; FIG. 4 - view of the pusher from the front; FIG. 5 - his plan view; FIG. b and 7 is a front and side view partly in section of the embossing drum.

The machine is driven by an electric motor through a worm gearbox 1 (Fig. 3).

To load the machine, it has two bins I and II (Fig. 1). The bunker consists of two cranes 2 and 3 (Fig. 3), forming a bootable ainnapaT. The square 2 is fixedly mounted on the stand-le 4, and. square 3 - movable, thanks

what makes it possible to vary the distance between the squares by applying to the soles of different lengths.

The sole is stacked in the bunker with a tail end to the side of the connecting square 2, i.e. towards the direction of movement of the sole.

Table 4 serves as the base for laying soles. Between table 4 and the fixed square 2 there is a gap (a) through which the sole passes from the bunker to the place under the embossing drum.

In order that the gap between the angle 2 and the tables 4 is not passed through the two soles (since the target is equal to the maximum size, INI of the sole is 6 mm), during the design of the thinner soles, an attachment consisting of a guide 5 is attached to the angle 2 retractable tongue 6 (Fig. 2), by which part of the slit closes to the desired size along the thickness of the sole. There is a gap of 3 mm between table 4 and square m 3. From this point, the shank of the pusher 7 begins its movement G. PoreD, pushing the sole from under the stack. When the pusher moves back through this gap, “6” can pass through the gap, because it is thicker than the height of the gap.

On the table 4, along the edges of the bunker, there are movable guide rails 8, 9 (Fig. 2), creating an extendable corridor in which the moving base moves.

Thanks to a special device, when turning the handwheel 10 in 01, the corridor sets itself along the width of the sole and of the bunker, i.e. the distance between the squares 2, 3 along the length of the sole (Fig. 2).

For convenience, the ycrasoEv n of the bunker is numbered to table 4 with an ogkala 11, showing the size number of the desired sole, graded according to the assortment available to the company.

Pointer 12, spliced on plaque 13, is labeled and, when rotated, the handwheel is set to

The corresponding division on the scale, indicating the size of the base (height).

When the handwheel 10 is rotated, the screw 14, rotating in a fixed rack 15, mounted on the table 4, moves the rack 16 and rigidly with the neii fastening bar 13 with the angle bracket 3. The bar moves along the guide 17. The bar 13 pushes the bars 8, 9 with pins 18, which are located in transverse slots x 19 of the bar 13. The bars 8 and 9, with their oblique grooves, pivot the pins 20 fixed in the table 4, and when they are moving forward, when the length of the bunker is reduced, they move towards the longitudinal axis of the bunker, narrowing corridor between the slats.

Under the square 3 between the bar and the table 4, the shank of the pusher 7 is placed in its initial position. The shank of the pusher 7 is the working part of the feeding mechanism. It receives reciprocating movement. When moving, the pusher pushes the lower sole itself, pushing directly on the table 4, from under the pile to the place where. the drums are located. In its final position, when the sole is pushed out, the tail part of the pusher 7 does not come out from under the stack: the soles in the bunker, and during its reverse movement it passes between the stack and the table and leaves the stack in its original position. The rear part of the shank of the pusher 7 is skipped (Figs. 4 and 5) so that during the return stroke the pusher returns to its original position unhindered.

The mechanism for feeding the sole of the embossing drum is designed as follows.

The bolts 21 (FIGS. 4 and 5) fasten the shank of the pusher 7 to the stand 22 sliding in the slot of the table 4 and to the plate of the pusher 23. The bolts 6 fasten the plate of the pusher 23 to the sliders of the pusher 24. The crawl of the pusher moves in the guides 25 attached to the bottom of the table 4. Main shaft 26

(Fig. 3) with the aid of a connecting rod-crank mechanism consisting of crank 27 and connecting rod 28, sets the mechanism of the pusher 7 into motion. During the movement of the tol1satel from the final position to the descent, the drum marks are lowered to the bottom of the drum, as a result of which the trademark and the logo are ionized. growth numbers. When the pusher 7 moves forward, the drum falls, and the sole moves with the pusher 7, the embossed sole located under the drum and takes its place. The embossing device (Fig. I-3) is mounted on: L-shaft 29. Shaft 29 lies in pilas 30, which run in guides 31. Co-rim: shaft 26 with eksdantrika 32, upper collar 33, lower collar 34 , a screw nut 35, a screw 36 and an earring 37, communicate to the shaft 29 and the marking rollers on it a vertical movement.

The embossing apparatus consists of multifaceted stamping markers 38 (FIGS. B and 7). Inside the drum, parallel to its facets, are four holes, in which electrical heating devices 39 are placed. They are used on piercing mashes. On eight grains of the drum, eight E-40s were strengthened with the reference: different growth numbers to the brand name. To hide the electric wires and thermal insulation, there are disks 41 and 42. The drum is mounted by means of a key on the sleeve 43. Three bronze rings 44 and insulating disks 45 between them are placed between the drum and the flange of the shoes, and together with the coals 46 they form a sliding contact. Three rings are made to ensure that only two heating n devices (out of four) are adjacent to the stamp 40 that is working and adjacent to them.

The power from the electrical network is supplied to the bronze. sleeves 47. Sleeves 47 are placed in a barrel made of electrically insulating material 48. Inside sleeves 47 there are springs 49, pressing the coals 46 to the contact rings 44.

The retaining ring 50 sits tightly on the shaft 29. In it is placed a device consisting of sterr; zhenka 51, springs 52 to the head. 53, fixing the position of the marking device by alternately hovering into eight holes, located in sleeve 43 against each stamp. To protect against longitudinal displacement of the drum, a second retaining ring 54 serves.

The distance between the punch 40 with the drum lowered and the tile is adjusted according to the thickness of the FOREST (the thickness of the base ranges from 3.5 to 6 mm).

Tiles 55 (Fig. 2), which are prismatic plates, are placed in the windows of the table 4. The tile in its lower part has a wedge-shaped protrusion resting in the bar 56, in which there are wedge-shaped grooves. The bar goes in guides 57 (Fig. 1).

The bar, moving in the transverse direction, lifts simultaneously both lifting platforms of the table.

The movement of the bar 56 is made by turning the steering wheel 58. A roller 59 rotates from the hand wheel. The wheel 4 serves as a bearing. A gear is placed tightly on the rack 67 that is welded to the bar 56, which moves it, thus adjusting the lifting platform. Adjusting the gap between the table and the stamp can also be done by turning the nuts 35 (Fig. 3).

The drive of the machine consists of an electric motor 60, a gearbox 1, a coupling 61, 62, a pair of gears 63 and 64 n of the main shaft 26. The main shaft drives the adhesive drums by means of an eccentric mechanism and a crank mechanism 27-28. soles.

For the convenience of placing the stamps on the desired number in the working position on the disks 41, 42, engraved stamp numbers from the opposite side to the working surface are engraved, i.e., the number engraved on top indicates the "number of the working stamp producing the impression in this position .

The rotation of the drum is carried out by pushing the head 53 and rotating it with a special key.

The subject matter of the invention.
