Description

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

A device (rotary scissors) for cutting veneer tape along the length [1].

A rotating knife drum contains a knife that cuts (cuts) the veneer tape into strips of a given length. 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).

Known shaper assembly line of wood laminated materials [2], comprising a feed mechanism containing a pressure roller, an adhesive application mechanism containing an applicator roller, and an assembly mechanism comprising a lifting table on a movable carriage.

The drawback of the shaper is the inconvenience in operation due to the separate execution of the operations of cutting veneer into strips, applying glue to the surfaces to be glued and assembling a packet from them.

The objective of the invention is the creation of equipment that performs simultaneously on one workplace the operations of cutting sheets into strips, applying glue to the surface of laminated materials and assembling a cellular bag from strips with a gap between them.

EFFECT: possibility of mechanization of the assembly process of cellular plywood, reduction of the amount of equipment used and the personnel serving it by combining several operations into one, ease of operation.

This is achieved by the fact that in the shaper of the assembly line of packages of wood laminated materials containing a feeding mechanism, an adhesive applying mechanism and an assembly mechanism, the feeding mechanism comprises an elastic pressure roller with knives installed along the radius, and the adhesive applying mechanism contains an applicator roller, the applicator roller installed with the possibility of adjusting its position relative to the elastic pressure roller, while the assembly mechanism includes a lifting table made with the possibility of rotation of the relative but its axis and is provided with the carriage, providing its reverse longitudinal movement further comprises guiding shaper determining the position of the sheet material, which are mounted in an elastic pressure roller along a circular arc. The shaper is configured to control the speed of movement of the movable carriage of the lifting table of the mechanism relative to the elastic pressure roller.

Due to the installation of a combination of a feed mechanism and an adhesive application mechanism inside an elastic pressure roller, the possibility of simultaneous operations of cutting wood laminate onto strips, applying adhesive to their surface and assembling a packet from them at one workplace has been created. 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.

The shaper is illustrated in the drawing.

The shaper contains mechanisms for feeding, applying glue and assembly. The feed mechanism contains an elastic pressure roller 1. Inside the elastic element of the pressure roller, knives 2 are installed along the radius to cut sheets 3 (layers) of material 3 into strips. The glue application mechanism comprises an applicator roller 4 that applies adhesive to the surface of the sheet 3, which is installed with the possibility of regulating its position relative to the pressure roller.

At the pressure roller 1 along the arc of a circle, guides 5 are installed that determine the position of the sheet 3. The lifting table 6 is equipped with a carriage 7, providing its reverse longitudinal movement, and any known device 8, which rotates the table 6 about its axis.

Table 6 is set so that its plane after laying the next layer of strips 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 an amount "h" equal to the thickness of the sheet 3. Value "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, table 6 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 4 is moved away from the pressure roller 1. The carriage 7 is turned on and sheet 3 is fed by the pressure roller 1. The guides 5 determine the position of the sheet 3 relative to the roller 1. There is no gap between the guides 5 and the surface of the elastic roller 1. Sheet 3 deforms the elastic element of the roller 1, while the knives 2 cut the sheet 3 into strips. Sheet 3 (without glue), cut into strips, from the guides 5 by the elastic element of the pressure roller 1 is laid with a gap between the strips on the table 5 as the outer layer of the package. The gap between the strips of the sheet 1 is formed due to the difference in the speed of movement of the carriage 7 and the peripheral speed of the pressure roller 1 (the peripheral speed of the pressure roller 1 is less than the speed of movement of the carriage 7). After laying the strips of sheet 3 on the table 6, the carriage 7 is turned off, the table 6 is lowered relative to the pressure roller 1 by the value “h”, the carriage 7 is turned on and the table 6 is returned to its original position, the device 8 rotates it 90 °.

The applicator roller 4 is moved to the pressure roller 1 to the gap "h". The sheet 3 is fed by rotating the applicator 4 and the pressure roller 1, while the applicator roller 4 is applied glue to the surface of the next sheet 3. The guides 5 determine the position of the sheet 3 relative to the roller 1.

When sheet 3 compresses the elastic element of the roller 1, the knives 2 extend beyond the surface of the elastic element of the roller 3 and cut sheet 3 into strips. The sheet 3 cut into strips with glue on the surface of the guides 5 by the elastic element of the pressure roller 1 is laid with a gap between the strips on table 6 as the inner layer of the bag. The elastic element of the pressure roller 1 lays strips of sheet 3 with glue on the previously laid outer sheet 3 of the formed package with a gap between the strips. After laying the strips of sheet 3, the table 6 drive is turned off, the table is lowered by the value “h”, the drive carriage 7 is turned on and the table 6 is returned to its original position, it is rotated 90 ° and the laying cycle is repeated. The number of stacking cycles is determined by the number of layers in the package. After laying the strip of sheets, the assembled package is unloaded by any known device, for example, a transfer device, and the table is raised to its original position.
