SI20259A - Joiner's cushion - Google Patents

Abstract

A joiner's cushion assembled as a self-contained unit/device is used in combination with a classic joiner's press for veneering of uneven or three-dimensional parts in joinery. It is composed of a base plate (1), intermediate frame (2), chamber (3), membrane (4), closing frame (5), attachment, (6) and handles. It is constructed in such a manner that it may be loaded simply on the press table and taken out after the application. By filling the chamber under the membrane, the required pressure on the veneer and the piece to be veneered is exerted, enabling thus an effective operation of the cushion.

Description

MIZARSKA BLAZINA

The object of the invention is a joinery cushion. More specifically, it is a device intended for gluing veneer and veneer-like materials to spatially shaped parts. Thus, with the help of a cushion, all uneven semi-finished products made of chipboard, mediapan and other materials used in According to the shape of the model, semi-finished products can also be pressed into the model with a cushion and thus pressed into the desired shape.

Technologically speaking, this is a well-known solution used by large systems. The novelty of the joiner's cushion is its compact integrity. The cushion is a complete unit that is used in support of a classic joinery press for flat panel veneer. It can also be used in an independent unit that replaces the joiner press (additionally, the cushion frame is made), The advantage over the known system having a fixed membrane is that the pillow is simply placed on the press table and removed after use and the press is again ready for the classic surface gluing.

This solves the problem of the inaccessibility and subsequent non-utilization of solutions so far known.

Figure 1 shows the shape of the joiner's cushion and its structure is shown in more detail by section A-A.

The joiner's pillow consists of:

Position 1 - Baseplate

Position 2 - Intermediate frame

Position 3 - chamber

Position 4 - diaphragm

Position 5 - Lock box

Position 6 - connector

Position 7 - handle

The base plate is made of thermally well conductive material (aluminum, ..........), which is the basis for the rest of the superstructure. The heat transmitted by the press table into the space under the membrane is transferred through it. as a body in which heaters are installed which allow the cushion to be thermally independent.

THE INTERMEDIATE FRAMEWORK is intended to close the height of the cushion belt and is the border of the chamber below the diaphragm. Use this box to determine the height we need for each semi-finished product. It can be arbitrary.

The CHAMBER is located between the base plate and the diaphragm and is the result of a built-in intermediate frame. When everything is ready for veneering, the chamber is filled with medium (air, water, oil, .....) and at the desired pressure.

MEMBRANA is a very important element of the cushion. It is made of an elastic material (rubber, ....), which allows the pressure created by the medium in the chamber to be distributed over uneven parts of the adhesive, and at the same time serves as a separator between the medium and the adhesive and in general allows the cushion to function.

The FINAL FRAME is one of the elements that completes the basic structure.

The CONNECTOR is used to connect the inlet pipe through which the required medium is supplied to the chamber under the desired pressure.

The handle is attached to the outer frame of the entire assembly and serves as an accessory for loading onto the press table and for taking it off the table.

OPERATION DESCRIPTION

A carpenter's pillow is loaded on the empty table of the press.

On the cushion membrane we place a formatted piece of veneer and the plate that we want to perforate. When this is done, close the press (squeeze the cushion between the lower and upper press table) and the system is ready to fill the chamber with the medium. Pressurized media, which squeezes the membrane together with the veneer to the veneer shape. We wait for the gluing to take place after a certain time, empty the chamber, open the press and take the veneer semi-finished product from the pillow. For the next piece, repeat the process.

Claims (1)

PATENT APPLICATION Joinery cushion, which is supported by a classic joinery press for veneering of semi-finished semi-finished products in joinery, characterized in that it is made as a complete unit with a base plate, frames for clamping the membrane, and thus the necessary chambers are provided into the chamber under pressure. the operation of the cushion and the fact that it has a finishing element with handles which allows it to be quickly and easily mounted on the press table.
