Description

The invention can be applied in the woodworking industry in the manufacture of glued parts from lump wood veneer, for example, parts for furniture production.

The goal is to increase productivity by combining operations.

Fig. T depicts a device, a general scheme; figure 2 is a view of And figure 1; on fig.Z - a package, at the time of submission to the subpress; figure 4 - section bb in figure 1 (the time of the sub-press operator beyond the dividing knives); FIG. 5 shows a pressed layer of veneer, longitudinal cutting; 6 shows a bag, feeding upwards by a lower subpressor; 7 - the same, lifting up and removing scraps; on Fig - section bB in figure 1 (laying the molded parts on the pallet); figure 9 - section bb In figure 2.

The apparatus for performing the method includes frame 1, mechanisms 2 and 3 for stacking the bag 4 from blanks 5 of piece veneer on the forming table 6, loader 7 of the bag 4 into the upper sub-press, table 9 receiving pallets 10, hot press 11, feeding mechanism 12 and drive 13 Package 4 consists of approximately 17 layers of 14.

The device is equipped with a device 15 for forming the profile contour 16 of the part 17, made in the form of a vertically movable plate 18 with the part 17 of the dividing knife set 19 mounted on the contour 16 and mounted on the frame 1 of the mirror knives 19 of elastic removable elements 20 and additional lower sub-pressors 21. 8 is movably mounted on the plate 18 between the knives 19. When forming the part 17, lateral tape trimming of veneer sheet 22 is obtained. Press 11 is provided with a storage device 23, and the sub-press operator has an additional drive 24. On The pack 23 is formed by the carrier 23.

The method is carried out as follows.

Mechanisms 2 and 3 produce a package 4 on the table forming 6 from blanks 5, pre-cut from lump veneer. The number of layers 14 in the packet is approximately equal to 17. The loader 7 moves the packet 4 along the table 6 to the upper sub-press 8 (FIG. 3).

An additional drive 24 lowers the upper sub-press 8 down to fix package 4, and drive 13 lowers plate 18 with dividing knives 19 (figure 4), which carry out sequential transverse cutting of layers 14 of non-glued package 4 (figure 5) and forming a complex the profile contour 16 of the part 17, and the underpressing layers 14 of the part 17 gradually, with greater friction, enter inwardly between the knives 19 (Fig. 6). For reliable cutting of the lower face layer 14, the knives 19 are incorporated into the elastic elements 20.

Thereafter, the lower sub-press 21 forces the part 17 inwardly between the knives 19 to prevent the lower layer 14 from falling out and increase the reliability of the pressing-in. The actuator 13 retracts the knives 19 with the sub-operator 8 (Fig. 7). Pallets are fed from table 9 to the sub-press to receive the formed product, while the pallet pushes the trimming 22 from the part forming area (Fig. 7). Next, the drive 13 again lowers the plate 18 until the knives 19 touch the pallet 10, while the sub-press 8 presses the product 17 to the pallet and the knives go up. So is the transfer of the product on the pallet, which is placed on the drive 23.

Consequently, the device 8 for shaping the part 17 produces a subpress of the bag, the transverse cutting of the unglued bag 4 and the laying of the piece 17 on the lower pallet 10. From the accumulator 23, the assembled pack 25 is loaded into the press 11, where the final shaping of the parts 17 occurs by gluing.

The application of the proposed device allows for the combination of operations to increase productivity, reduce noise and operator fatigue, as well as improve the quality of products.
