Description

The invention relates to the woodworking industry and can be used in the manufacture of wood laminated materials, such as plywood.

A device is known for the continuous application of glue on the surface of a wood laminate, comprising a supply and an applicator roller [RU 2162750 C2, 11/13/1998].

The feed (push) roller contains a cylinder with elastic bristles, which allows you to apply glue on strips of material of different thicknesses.

The disadvantage of this device is its limited technological capabilities (the impossibility of combining the operations of applying glue to the surface of laminated materials and assembling packages from them).

Also known is the assembly line of packages of wood laminated materials [Volynsky V.N. Technology of glued materials: Textbook for universities. (2nd ed., Revised and supplemented). Arkhangelsk: Publishing House Arkhang. state tech. University, 2003, p.123-124], containing a feed mechanism, a mechanism for applying glue to the surface and an assembly mechanism with a lifting table, which are essentially a shaper of the assembly line of wood laminated materials.

The disadvantage of this line is the complexity of its design, high metal consumption and cumbersomeness, inconvenience in operation due to the separate execution of operations for applying glue to glued surfaces.

The objective of the invention is the creation of equipment that simultaneously performs the operation of applying glue to the surface of the layered materials and the assembly of the package from them in one workplace.

Effect: simplified design, ease of use.

This is achieved by the fact that in the shaper of the assembly line of packages of wood laminated materials, including a feed mechanism containing a pressure roller, an adhesive application mechanism containing an applicator roller, and an assembly mechanism comprising a lifting table, an applicator and a pressure roller are installed opposite with a gap, and the lifting table the assembly mechanism is mounted on a movable carriage with the possibility of rotation about its axis, the applicator roller is mounted with the possibility of adjusting its position relative to the pressure roller. By combining the feed mechanism and the glue application mechanism, it was possible to carry out glue application on the surface of the laminated materials and assemble the package from them at one workplace. The shaper is simple in design and convenient to operate, provides the ability to reduce the number of equipment used and the number of personnel serving this equipment.

The shaper is illustrated in the drawing. The shaper contains mechanisms for feeding, applying glue and assembly. The feed mechanism comprises an elastic pressure roller 1. The glue application mechanism comprises an applicator roller 2 that applies adhesive to the surface of the sheet 3 (layer) of material, which is installed with the possibility of adjusting its position relative to the pressure roller. At the pressure roller 1 along the arc of a circle, guides 4 are installed that determine the position of the sheet 3. The lifting table 5 is equipped with a carriage 6, which ensures its reverse longitudinal movement, and any known device 7, which rotates the table 5 about its axis. Table 5 is set so that its plane after laying the next sheet can be lowered in any known manner, for example using a rocker mechanism (not shown), relative to the lower edge of the pressure roller 1 by a value of "h" equal to the thickness of sheet 3. The value of "h" - adjustable.

The shaper design uses well-known parts and assemblies. Shaper assembly line package wood laminated materials works as follows.

In the initial position, the table 5 is lowered relative to the pressure roller 1 by an amount "h" equal to at least the thickness of the sheet 3, and the applicator roller 2 is moved away from the pressure roller 1. Turn on the carriage 6 and at the same time press sheet 1 feed sheet 3. Guides 4 determine the position of the sheet 3 relative to the roller 1. When the sheet 3 leaves the guides 4 with the elastic element of the pressure roller 1, sheet 3 (without glue) is laid on table 5 as the outer layer of the bag. After laying sheet 3 on table 5, the carriage 6 is turned off, table 5 is lowered relative to the pressure roller 1 by an amount of "h", the carriage 6 is turned on and the table 5 is returned to its original position and rotated 90 °. The applicator roller 2 is moved to the pressure roller 1 to the gap "h". Sheet 3 is fed by rotating the applicator 2 and the pressure roller 1, with the adhesive roller 2 applying glue to the surface of the next sheet 3. The guides 4 determine the position of the sheet 3 relative to the roller 1. The elastic element of the pressure roller 1 lays sheet 3 with adhesive on the previously laid outer sheet 3 formed package. After laying the sheet 3, turn off the table drive 5, lower the table down by the value of "h", turn on the drive carriage 6 to reverse and return the table 5 to its original position, turn it 90 ° and repeat the laying cycle. The number of cycles depends on the packet layer. After the laying of the sheets, the assembled package is unloaded by any known device, for example, a transfer device, and the table is raised to its original position.
