Description

[Detailed description of the invention] The present invention is mainly concerned with the manufacture of knee shoes with rubber soles such as athletic shoes.

One of the methods is to attach the rubber shoe sole to the inner surface of the upper that is fitted over the shoe shoelace using rubber soles.

Conventionally, in the case of rubber sole rings, K adheres to the insole of the upper, which is the sole of the shoe.
First, the sole of the shoe is bonded to the midsole using flK in the form of raw rubber, and then hot water treatment is performed to harden the adhesive. This fixation of the sole to the midsole is extremely difficult, as it will prevent the sole from accidentally peeling off from the midsole even after long-term use or intense exercise! It is desirable that it be firm. Therefore, when bonding the rubber to the insole of KiIk's first shoe sole, it is important to ensure uniform pressure bonding. Therefore, in the past, a TT shoe sole with a raw rubber decoration on the entire insole was placed in close contact with a sponge plate, and a pressure of 511 force was applied to the entire surface of the sole from a pressure plate through the sponge plate. I was having a good time. The swelling surface of the sole of a shoe is usually formed with an uneven pattern of uneven height.On the other hand, the pressing surface of the pressure plate is flat, so even if pressure is applied through a sponge plate, the pressure will not be affected. The pressure was slightly applied to the central part and the 1000 pieces of wood (it worked, but it became weaker at the edges of the shoes, and there was no sufficient adhesion).So, when the pressing force of the pressure plate was made strong, the shoes The periphery of the sole is also pressed lightly, and the adhesion is made strong enough to be adhered to, but even if the sponge version is being used in the dark, the strong pressure leaves impressions from the stamp on the sole surface of the shoe, and the pattern on the sole surface of the shoe is distorted. This has the disadvantage that the periphery of the shoe sole is stretched, causing it to curl up and deform. Pressure was applied to the periphery of the shoe sole using a Kii sewing machine roll as a waste of time when adhesion was insufficient.This may be the solution.In the past, in addition to applying pressure using a pressure plate, it was not necessary to apply pressure using a sewing machine roll. The present invention eliminates the above-mentioned drawbacks, and provides a device that enables uniform adhesion of soles in one processing step and ensures and strengthens adhesion during subsequent vulcanization treatment. The construction of the present invention will be explained below with reference to the drawings.

In Fig. 7, 111ii moving wheels 4 are located directly above the 9 fixed lower stands (1°), and the 9 movable upper stands are installed so that they can be raised and lowered.

The fixed lower base 111 is formed into a hollow box shape as shown in the figure, and is round.

Install it at an appropriate height in front.

Shoes W III are supported in a suspended state from the upper surface plate (41) regardless of their size. A vacuum pump (not shown) installed in the camphor 141F acts on KQl in the hollow part.IFi

9. The movable upper platform (2) is a support 9 that is erected on the base (3).
The lifting drive unit installed on the upper part of the platform, for example, the air cylinder shown in the drawing, is attached to the lower end of the piston rod (14) at the 0 position. A large through hole 9?) is made in accordance with the external shape of the bottom plate, and the bottom plate is held between the bottom plate and the bottom +1ii1! 1. Also, 1. An air circulation pipe is installed between this top plate.

Next, we will explain how to press the inner sole of the shoe with the resoso.

As shown in Figure 1 in advance, the shoelace (i) K-covered upper skin (
Glue the sole (1) to the inner sole (a&) of 81 with raw rubber. In addition, the movable upper platform of the device i! ) is kept stationary in the raised position 11 by driving the air cylinder fAH as shown in No. 1-.
Insert the ankle (Ib) side into the box body through the vertical insertion hole (6) of the top plate (4) of the lower stand (0), and adjust the left and right value 1 to match the size and shape of the shoe last (i). It is supported by the support members (Ma) whose height has been adjusted with support parts (Ma) ('Fb). For the vertical insertion hole (-) K, an equally divided groove It (ml) is formed on the periphery of the hole to slightly protrude from the top plate (4). Next, drive the air cylinder H, raise the movable plywood (phantom), and set it in place.
The bottom plate descends until it comes into pressure contact with the top plate (4) of the fixed base plate (II).As a result, the rubber membrane stretched over the through hole η of the bottom plate covers the entire surface of the shoe I!(・). At the same time, as the sole (II) protrudes from the top plate (4), it expands and tightens with elasticity.As a result, the sole (・lF1gogoll!!) is pressed by the ring, and the entire midsole (@ &) Crimp K. * Drive the vacuum pump with Niko ζ and press the hollow WAK of the constant lower base (1).

6. It is also possible to supply pressurized air from the "flow pipe" to make the crimping even stronger.As explained above, for misfire #4, insert a shoe sole with rubber sole adhesive into the top plate. A hollow 11k-shaped fixing lower base is provided with an inner SK shoe last holding member, and a hole in the Il-shaped sole plate is made larger than the sole. Place the rubber 114 on the side and insert the rubber 114 into this hole, and install the movable upper stand directly above the fixed lower stand so that it can move up and down. The sole of the shoe, which is attached to the last attached to the fixed lower part, protrudes from the upper plate of the fixed lower part. As a result, a gap of an appropriate width is formed between the periphery of the sole and the rim of the insertion hole due to the large insertion hole in the sole of the shoe, and the through hole in the movable upper base of the rubber crotch is also inserted into the sole. The rubber membrane, which is larger than the external shape, tightly covers the entire sole of the shoe, including the 111 part between the periphery of the protruding part of the sole, and covers the part between the intake rows. % to rubber membrane
Due to the strong force, shoe a is strongly pressed to the insole all the way to its periphery, and due to the elasticity of the rubber membrane, the pressing force is applied to the entire surface of the sole Kj@
Also, if the periphery of the sole is rolled up, the pattern on the sole will not be damaged.

The present invention fi11ilfFi horizontal 11ilfF It can be done in one step without requiring post-processes such as the conventional pressurization of the sole periphery using a scolding roll, and it is simple and easy to operate, and the entire sole is evenly crimped and finished.

The vulcanization effect in the next step is the same as above.
