Description

one

The invention relates to devices for disassembling packages of sawn timber and can be used in the woodworking industry.

A device for dismantling packages of sawn timber is known, comprising a frame on which a lifting table is installed, a vertical guide wall and pressure posts, and also a pusher 1 located above the table.

The disadvantage of this device is that if there are warped lumber in the package (after drying), they can be captured not only from the top, but also from the next row. In addition, the device requires adjustment of the gap between the presser stands when changing the width of the package being disassembled.

The purpose of the invention is to increase the reliability of work with curved materials,

The goal is achieved by the fact that the proposed device is provided with a conveyor located above the table with vertically closed traction bodies spaced across the table, connected by a pair of axes,

and the pusher is made in the form of a row of hooks hinged on one axis, and their ends are connected to the second axis, the flexible threads.

5 In this case, the clamping pillars are hinged on the frame, are connected to it by springs and have the shape of a sector in cross section.

This embodiment of the device

O provides for the capture of only one p and sawnwood.

Figure 1 shows the described device, the side view of figure 2 is the same, top view; on fig.Z - section

.15 A-A in FIG. 2

The device consists of a frame 1, on which a lifting table 2 is placed, a vertical guide wall 3 and clamping posts 4, which are rotatably mounted on hinges 5 in slots x, made in the lift table 2. The clamping stands are in the initial position. stops 7 springs 8 and have

25 in cross section the shape of a sector.

The frame is equipped with folding fixing posts 9 with pads attached to them and locks 11. A conveyor 12 is located above the lifting platform 2.

spaced vertically stalled by the closed-loop traction bodies 13 connected by axes 14 and 15, rollers 16 are fixed at the ends of axes 14 and 15, moving in guide rails 17 of conveyor 12, the pusher is designed as a row of hooks 18 articulated n. axis 14 independently of one another, the ends of which are connected to the axis 15 by flexible threads 19.

A limit switch 20 is installed on the conveyor frame, the lever 21 of which can freely pass between the lugs 18 during their movement.

The conveyor is driven by the electric motor 22 and has a tensioning mechanism of the traction member 23

The device works in the same way.

Racks 9 are opened and the package of sawn timber is placed on the lift table 2. Racks 9 are closed and locked with locks 11, Pressing racks 4 under the action of springs 8 are pressed to the package and fixed its position relative to the racks 9. Thus, the racks tightly clamp the package, with different its width and do not bark it to fall apart.

To output the top row of planks, the lift table 2 rises until the top row of boards presses the lever 21 of the limit switch 20. The limit switch 20 is set so that its lever 21 controls the raising of the table 2 to the level when the bottom plane of the row will be above the guide wall 3 The conveyor 12 is turned on. The crocci 18, moving together with the traction body 13, abut the front surfaces on the ends of the planks and slide along them on the axis 14 (FIG. 3, position I). Due to the fact that all the crocs 18 are planted on the axis 14 and are suspended on flexible threads 19 independently of each other, from the moment the butt end touches the boards it turns on the opre, the target angle and with the further movement of the conveyor body hooks 18 with their working surfaces capture board (position II on fig.Z

only the upper row, regardless of the transverse dimensions of the boards and their warping. Upon further movement of the boards, the lever 21 of the final switch 20 is released, and the lifting table rises to the level of the next row,

To ensure the reliability of the separation of only the top p and sawn timber, the width of the working part

separate hook must exceed

the size of the gap between the lumber in the row, and the height (depth H of the grip, fig. 3) of the working part of the hook 18 must be less than the minimum thickness of the lumber.

Due to the execution of the collider in the form of a row of hooks fixed independently of each other on the same axis, the ends of which are connected by flexible yarns to another axis, only the upper row can be separated from the package when working with curved lumber.
