RU2297909C2 - Device for lamination of plates - Google Patents

Abstract

FIELD: woodworking, in particular, devices for hot lining of constructional, furniture, etc plates.

SUBSTANCE: the device for lamination has a press containing a diaphragm forming a pneumonic cell, and the lower horizontal plate communicating with a compressor, upper horizontal plate with a drive for its motion, and a heating device. The device has also a mechanism for feed to the press and removal from the press of pieces of work, made in the form of a belt conveyor. The upper horizontal plate of the press is provided with a device for its heating, faced with sheet aluminum for adjustment of the charging clearance relative to the blank thickness. The diaphragm is fastened with a clearance on the lower horizontal plate of the press for provision of a uniform increase of pressing of the blank to the upper horizontal plate at working.

EFFECT: provided qualitative sticking of the facing material over the entire area of the plate having deviations in the size of the thickness on its area.

Description

The invention relates to woodworking, namely: to devices for hot cladding of building, furniture, etc. plates (fiberboard, DVL, GVL, etc.) paper, film, plastic, veneer.

Known hydraulic presses model GP-60; GP-80 for covering with paper, plastic, veneer, full-length plates or pre-cut blanks, including plates for placing blanks between them, a plate heating system, plate movement mechanism for compressing blanks (see the copy from the information source on a separate sheet).

A device is known for double-sided cladding of furniture panels, including a table for blanks, a hydraulic press PSGE-1M, containing lower and upper horizontal plates with hydraulic drive for moving the lower plate for crimping blanks, a mechanism for heating the plates, a mechanism for removing the finished product from the press (see copy from the source of information on a separate sheet).

The closest analogue of the claimed invention is a device for laminating plates according to the application DE 3935562 A1, 05/02/1991, including a press containing a membrane forming a pneumatic chamber and communicating with a compressor, a lower horizontal plate, an upper horizontal plate with a drive for moving it, a heating device.

A disadvantage of the known devices is the low quality of the coating for plates having some deviations of the thickness size in area, due to the implementation of plates for crimping workpieces from hard material.

The technical result of the claimed technical solution is to ensure high-quality bonding of the facing material over the entire area of the plate having deviations of the thickness size over its area.

The technical result is achieved by the fact that the device for laminating plates includes a press, contains a membrane forming a pneumatic chamber and communicating with the compressor, a lower horizontal plate, an upper horizontal plate with a drive for moving it and a device for heating, according to the invention, the device further comprises a feed mechanism to the press and removal of products from the press, made in the form of a conveyor belt, while the upper horizontal plate of the press is equipped with a device for heating it, lined with sheet Yuminov for setting the boot lumen relative to workpiece thickness and the membrane is secured with a clearance on the lower horizontal plate press for effecting uniform gain clamping the workpiece to the upper horizontal plate during processing.

The supply of the lower press plate with a membrane rigidly fixed on it, with the formation of a pneumatic chamber communicating with the compressor, provides high-quality lamination of building and furniture plates, including those having a deviation in the size of the plate thickness over its area, because the support for the workpiece in the form of an elastic chamber tightly touches at each point on the surface of the workpiece and therefore creates a uniform force of pressing it to the upper plate, and, therefore, uniform heating from the aluminum sheet of the upper plate.

The device for laminating plates includes a table 1 for blanks, a press containing the upper plate 2, lined with aluminum sheet 3 and provided with a heating mechanism, the lower plate 4, which acts as a support and placed on the frame 5. A membrane 6 is fixed with a gap on the lower plate 4, made, for example, of rubber grade TMKSH, forming a pneumatic chamber 7, communicating with the compressor. The press simultaneously comprises a drive for moving the upper plate 2 and a mechanism for removing finished products from the press, made, for example, in the form of a conveyor belt 8.

A device for laminating plates works as follows. The plate intended for cladding is laid on table 1, the adhesive composition is applied to the surface of the plate and cladding material (paper, film, plastic or veneer) is applied to it. Then, the plate is transferred to the conveyor belt 8 and fed into the loading gap between the aluminum sheet 3 of the upper heated plate 2 and the membrane 6 of the pneumatic chamber 7 of the lower plate 4, while moving the upper plate 2 sets the loading clearance 10 mm larger than the thickness of the workpiece. Then the pneumatic system valve is opened and the air from the compressor is fed into the pneumatic chamber 7, while the workpiece is pressed to the aluminum sheet 3 of the upper plate heated to the required temperature (100-180 ° C) 2. The required temperature is maintained using the sensor-regulator, and the required specific pressure is by setting the electrical contact pressure gauge. The pressure is maintained for a predetermined time, then released, and the finished product with a lined surface is moved by conveyor 8, removing from the press.

An easy-to-manufacture laminating device that provides high-quality coverage in one cycle of full-format plates, as well as pre-cut blanks of fiberboard, DVL, GVL, paper, film, plastic, veneer, will find industrial application.
