Automatic palletizing machine

Abstract

The invention discloses an automatic palletizing machine. The automatic palletizing machine is provided with a board receiving mechanism mainly composed of a board receiving device, a downward pressing device and temporary board receiving devices symmetrically arranged on two sides of the output end of a conveying mechanism. When the machine is in work, a transmission shaft is driven to rotate bya third driving device, so that a crank connection rod component connected with a rotation shaft drives clamping boards to do reciprocating actions of opening or closing, and thus a board can be accurately clamped, meanwhile the arranged downwards pressing device presses downwards, the board is effectively pressed down and palletized, and the board is prevented from blocking the machine. Therefore, the board receiving mechanism adopted by the invention can accurately carry and effectively level the boards, automatically and orderly palletize the boards, and also can solve the technical problems that the boards cannot be palletized due to the fact that the surfaces of the boards are uneven, and the boards deviates during a conveying process; and palletizing of the boards adopts a way of receiving the boards from the bottom up, so that the machine has the advantages of being good in palletizing effect, prevented from being blocked, not easy to wear and high in security performance.

Description

technical field [0001] The invention relates to wood processing equipment, in particular to an automatic stacking machine, which belongs to the technical field of wood processing. Background technique [0002] At present, in the wood processing market, a skin picker or a stacker is often used to transport and stack the veneer coming out of the rotary cutter. When stacking veneers, the board structure at the output end of the existing skin picker / stacker moves from top to bottom as the height of the stacked boards increases, that is, the continuous board connection from top to bottom . For example: [0003] First, the authorized announcement is a Chinese utility model patent of CN206735373U disclosing a kind of automatic plate stacker, the frame (4) is provided with a rotating plate divider cylinder (8), and the plate divider cylinder (8) outer circumference There are a plurality of arc-shaped splitters (7), and a plate slot A is formed between adjacent splitters (7). The...

AI Technical Summary

Problems solved by technology

When the board is not smooth enough, it is extremely easy to get stuck, especially dry wood (the board peeled out of dry wood is lighter in weight and more curled), and it is easier to get stuck; in addition, when encountering a rotten board , second-level boards, and perforated boards are also easy to jam, and the stacking effect is greatly reduced. It is not suitable for automatic stacking of thinner boards.

[0005] 2) The lifting platform (14) used to collect the plates moves from top to bottom with the change of the stacking height of the plates (that is, the way of continuous plate connection from top to bottom), and the plates stacked on the lifting platform always need the first chain 5. The second chain 6 and the cylinder 17 are used for supporting and pulling. The single-stacked slabs of the lifting platform reach the stacking height, and the total weight is generally 400-500KG. short service life

[0006] 3) Since the height of the lifting platform will change in the vertical direction, it cannot adapt to the working mode of various board handling

[0008] 1) The lifting device 5 it adopts is mainly composed of a third drive assembly 51, a steel wire rope 52, a fixed pulley 53, a lifting bracket 54, a rotating device 541, a pulley 55, and a slide rail 56. The bracket 54 also moves from top to bottom as the stacking height of the boards increases. When the single stacked boards of the lifting bracket 54 reach the stacking height, the total weight is generally 400-500KG, which is used to lift the lifting platform. The components of the hoisted wire rope 52, fixed pulley 53, pulley 55 and slide rail 56 are prone to wear and tear due to continuous heavy operation for a long time, posing potential safety hazards;

[0009] 2) The slider 433 and the guide rail 434 in the opening and closing device reciprocate about 40,000 times a day. When it reaches 2 million times, the wear and tear will change significantly. The worn slider and guide rail will cause the connecting plate 431 to break Offset affects the stacking effect of the boards; in addition, although it is equipped with a leveling device, when the boards are not flat enough, the stacking effect is not ideal

[0010] Therefore, it is not difficult to conclude that the board connection structure of the output end of the automatic skin picking machine / stacking machine listed in the first and second lists adopts a continuous board connection method from top to bottom. It needs to be shut down after working with stacking, and it cannot achieve the purpose of continuous work for 24 hours, which greatly affects work efficiency
