Description

The invention relates to equipment for the shoe industry, and more specifically to devices for tightening the drawn edge of a shoe blank worn on a shoe on the insole, for subsequent tousling of the drawn edge, applying glue and attaching the sole.

The device No. 1187521 A43d 71c-23/02 is known on February 18, 1965. It is proposed to tighten the gel part of the shoe blank worn on the shoe using a plate-like plate spring of a certain design. The disadvantage of this device is the limited use. For a particular shoe style, appropriate equipment is required, which is bulky and takes up a lot of space in the working area.

Domestic machines for tightening the nose-bundle part of the shoe blanks ZNK-2, ZNK-3 and ZNK-3m are closest to the use of the proposed device in them: combined long plates with superplastic plates. Pads are fixed on the toe and heel of the processed shoe. Tightening of the nose-beam part of the workpiece is carried out by ticks. Tightening the long edge onto the insole with long plates that are mounted in the beam with the possibility of radial movement and make a kinematically complex movement. The bundle part of the shoe blank with the lingering plates is partially tightened on the toe side.

The purpose of the invention is to combine two technological operations, tightening the protracted edge of the forefoot portion of the shoe blank and tightening the gel portion into one: tightening the protracted edge of the forefoot portion of the shoe blank worn on the shoe. Improve the build quality of shoes.

The problem is solved by the invention of combined tightening plates, which can be set to process the left or right half pairs of shoes with cylinders on command.

This goal is achieved by the fact that the combined long plates (hereinafter referred to as “KZP”) have a tail section, and the rest in design coincide with the long plates for tightening the forefoot portion of the shoe blank in ZNK-2, ZNK-3 and ZNK-3m machines.

KZP are pivotally connected, mounted in a traverse with the possibility of radial movement and make a kinematically complex movement. In the tail section of the KZP in the guides are placed and spring-loaded sliders with a fixed axis and a finger, on the axes of the sliders rotary plates are installed — discs with a hub, on which copiers with a profile of the field and inner side of the long edge of the gel part of the shoe are placed, copiers for high-heeled shoes made removable, an open groove and a stone pivotally connected to the mechanism for turning the supra plate in accordance with the field and inner sides of the gel part of the shoe, while installing and fixing ii shoe uppers to the workpiece between the forefoot and heel stops and subsequent movement with the slides PPC nadplastinnikami fingers are cams (not shown), the spring is compressed and the middle pads exhibit nadplastinniki automatically.

The mechanism for turning the supraplate in accordance with the field and inner sides of the gel part of the shoe consists of a prismatic ruler placed in the slide rails, pivotally connected to the stone on one side, and the other end cylindrical, with a spring-mounted shock absorber and an earring with a hinge, connected to the cylinder rod mounted on the beam, while the angle of rotation of the plate is regulated by the way stops.

In order to expand the range of processed sizes, shoe sizes of KZP shoes with superplastic plates with removable copiers of the gel part of shoes can be made with removable superplastic plates with a profile of the protruding edge of the tufted part of the shoe rigidly installed in the grooves.

Figure 1 shows the combined tightening plates with platens for tightening the toe-gel part of the shoe blank worn on the block, front view, figure 2 is the same, top view;

In Fig.3 combined combination plates with platbands of the tufted part of the shoe;

In Fig.4, the kinematic diagram of the combined draw-in plates with supra-plates.

The combined drawback plates 1, 2 of FIGS. 1, 2, 3, 4 are pivotally connected, have a tail portion, otherwise they coincide in design with the drawback plates for tightening the forefoot portion of the shoe blank. In the tail section of the KZP are placed guides “dovetail”, blind hole and a closed groove. Slides 3, 4 are installed in the guides, and springs 5 are installed in the blind hole. Bolts 6 of the sliders enter the closed groove of the KZP and hold the springs in a compressed state, and the sliders in their original position.

Axes 7 and fingers 8 are rigidly mounted on the sliders 3, 4. The plates 9 and 10 are rotatably mounted on the axes 7; these are disks with hubs on which copiers are made in a circle with a profile of the field and inner side of the long edge of the shoe shoe, an open groove and a stone eleven.

For high-heeled shoes, the disc hubs are used to install removable copiers 12, 13 of the field and inside of the gel part of the shoe, an acute-angled tooth is cut at their end, a “mouse tooth” with the help of which the plates are rigidly fixed with screws 14.

In the guiding sliders 3, 4, prismatic lines 15 of the supra plate turning mechanisms are placed in accordance with the field and inner sides of the gel part of the shoe with a direction of movement parallel to the dovetail guides of the KZP. One end of the prismatic ruler 15 is pivotally connected to the stone 11, the other end of the prismatic ruler is cylindrical with a thread on which a spring - shock absorber 16, an earring with a hinge 17 and a nut 18 are mounted.

Earrings with a hinge 17 are connected to the rods 19 of the cylinders mounted on the beam. The spread and installation of the over-plates in accordance with the field and inside of the gel part of the shoe is carried out by the cylinders 19 along the track stops fixed to 20 and adjustable 21. The final position of the plates is fixed by the clips 22. The stops 20, 21 and the clips 22 are mounted on the sliders 3, 4. Regulation the stiffness of the springs - shock absorbers is carried out by nuts 18. With the fingers 8, the sliders are installed in the middle of the block, are found on the cams (not shown in the drawing).

To handle a larger range of sizes, shoe sizes KZP 1, 2 in the beam part can be made with a special groove for installing supra plates with the profile of the long edge of the beam part of the shoe 23 with rigid fastening with screws 24.

The device of the combined tightening plates works as follows.

Swivel KZP 1, 2 installed in the beam. At the command of the cylinders 19, the super-plates 9, 10 with copiers 12, 13 are set in accordance with the field and inner sides of the gel part of the processed half pair of shoes. The cylinder rods through earrings with a hinge 17 in the guiding sliders 3, 4 move the prismatic rulers 15 pivotally connected to the stone 11 and unfold the platelets 9, 10 on the axes 7 of the sliders 3, 4, exposing their copiers in accordance with the field and inner sides of the gel part half a pair of shoes on the track stops 20, 21, their position is fixed by latches 22.

When installing and fixing the pads with the workpiece upper between the toe and the heel stops and the subsequent movement of the KZP, the sliders 3, 4 with the plates 9, 10 with their fingers 8 are placed on the cams (not shown in the drawing), compress the springs 5 and put the plates 9, 10 in the middle of the block automatically. KZP, carrying out a kinematically complex movement as a whole, pulls on the toe-gel part of the shoe blank on the insole of the block.

All axial movements of KZP 1, 2, associated with a kinematically complex movement in the process of tightening the long edge of the shoe blank, are perceived by springs 5 and shock absorbers 16, while the sliders 3, 4 remain in the installed position in the middle of the shoe, and fingers 8 are pressed to the cams.
