Description

Machines for the seasoning of skins or leather goods, especially footwear

1 is a schematic cross-sectional view of a machine in a working or operating position.

2 is a partial cross-sectional view of the same machine in an open state.

3, 4 and 5 illustrate exemplary embodiments of support baskets of various types of footwear.

The present invention relates to a machine for achieving a seasoning operation suitable for products made of skin or leather, in particular footwear, wherein the operation involves the removal of moisture and solvent vapors in a short time for the skin or leather during the process, in particular during the process involving the use of adhesives. Extract, spray and remove.

Currently machines for accomplishing this task are well known. Such machines, however, which are not like the machines according to the invention, are conceived and designed for very high continuous cycle production, whereby their use is economical only in large scale plants. In addition, the structural idea of such machines is not intended to allow the manufacture of not many models or designs for limited production.

It is therefore an object of the present invention to provide a machine for the sizing of skins or leather articles, in particular footwear, which can overcome the disadvantages mentioned. In particular, the machine can be advantageously used for not much reduced production and also has convenient applicability for high yields and convenient applicability for many series of the same or similar models or designs and limited series of other designs.

These objectives are generally associated with a system comprising an electric fan and heat sources for air circulation and heating and suction provided with a receiving tank, steam injector and vacuum pump closed by a fully enclosed lid. Achieved by a machine for the seasoning of skin or leather products, in particular footwear, including devices, and the like. By the way, a basket for supporting a product to be handled or processed is inserted into the tank.

BRIEF DESCRIPTION OF THE DRAWINGS In order to more clearly understand the present invention, detailed description will be made with reference to the accompanying drawings by special embodiments suitable for handling footwear.

In the figure, the seasoning machine 1 of skin or leather comprises a tank 2 whose top is completely enclosed by a cover 3 provided with a gasket 4. Opening and closing of the lid 3 is provided by an oleodynamic device 5 which is bound to an adjustment lever 6 pivoted on 7. The opening and closing may be automatically or manually according to a prescribed program and is performed by a conventional electric programmer.

The heat sources 8, 9 are provided in the tank 2 and include an electric resistor or infrared light which serves the internal purpose of the tank and in particular serves the heating purpose of the shoe part where special sizing effects such as the front and heel are required. The steam atomizers 10, which are connected to the tank or chamber 2 and provided in the preheated chamber 11, inject steam and are injected into the tank 2 by mixing with the hot air circulated by the electric fan 12 and carried by the basket 14 Penetrates 13 skins or leather.

This first dehumidification step, apparently caused by hot air, is achieved after the shoes 13 are placed on the basket and then the lid 3 is closed. The cover 3 includes rods 16 extending from the laterally positioned binding member 17 of the basket 14 provided with rollers 18 sliding laterally in the guides 19 of the tank 2; Paired engagement members 15 are provided on the side.

During opening and closing the cover 3 only lifts the basket 14 and thereby inserts and removes it into the tank 2.

The mentioned dehumidification stage, which is programmed in duration and is achieved automatically and is caused by hot air, is accompanied by an extraction and stabilization stage that occurs when the vacuum pump 20 is operated and the pump 20 is connected to a pipe union 21) extract all air, water vapor and solvent vapors. The vacuum relief valve then automatically operates to open lid 3 to withdraw the basket from tank 2 when the lid is fully opened after a predetermined duration under vacuum, so that the seasoned shoe can be removed artificially. And the shoe to be treated may be re-received.

As shown in FIG. 1, the machine is completed with a small boiler 22 and a vacuum pump 20 for steam production.

However, the machine can be directly tied to an external vacuum system and similarly to an external steam distributor.

Top panel 23 forms the throttle and support of the electrical device to automatically achieve a complete processing cycle. However, they are not shown or described as they are conventional members.

As can be seen in the additional figures, the support basket 14 can be formed in different ways, depending on the type of skin or leather article, in particular on the type of shoe to be supported.

Therefore, a crosspiece 24 having a plurality of vertical pins 25 spirally coupled with the model 26 supporting the upper shoe 27 shoe may be provided or a cross having a plurality of side grooves 29 for application to the long shoe 30 light. Piece 28 may be provided.

When seasoning is required on the leg as well as the foot of the boot, the basket 14 has a number of extensible boot leg holders suitable for stretching the skin or leather of the boot. 31 will be provided.

In some cases, the basket 14 may provide a heat source 8, 9 to be processed or to be processed if the operator has to continue holding the product in the basket due to technical and human problems. It has two small side walls 32 to protect it from.

With the cover 3 fully open, the basket 14 is pulled out of the tank 2 to its maximum and the side walls 32 form two protective barriers in front of the heat sources 8 and 9 which are in continuous operation.

During operation, as shown in FIG. 1, the electric fan 12 draws air from the bottom of tank 2 and pushes it upwards through the heated chamber 12, where air is released from the sprayer 10 By pushing it back into the tank 2 adjacent to the heat sources 8 and 9 and then by the shoe of the basket 14 and then moving it to the inlet 33 to heat it. Results in a closed circulation cycle.

The above-described embodiments may be modified by those skilled in the art without departing from the scope of the present invention.
