Description

Pre-separation device suitable for high-speed automatic feeding of large plate

Technical Field

The utility model relates to a wood working machine technical field especially relates to a preseparation device suitable for big board high-speed automatic feeding.

Background

In the woodworking industry and the panel furniture industry, one of the intermediate products is a raw material large panel with a certain size and specification, when the raw material large panel starts to perform an order sheet production and processing process, the raw material large panel firstly enters a process preparation end from a specified position, then each step required by the processing process is gradually completed according to a process flow, and the process that the raw material large panel enters the processing process end is called as a raw material large panel feeding process.

The feeding process of the raw material large plate comprises two main processes which are respectively as follows:

1. and (3) carrying raw material large plate stack codes, and conveying a batch of raw material large plate stack codes with the same size and specification and fixed quantity to the process inlet end of the production line through a forklift in the factory.

2. And respectively sending each large plate in the raw material large plate stack to a process inlet end of a production line one by one, so that the raw material large plates enter the production line one by one through the process inlet end of the production line, and starting the processing process of the plates.

At present, various manufacturers in China basically realize the automatic feeding process of raw material large plates, and the conventional realization mode is to complete the rapid feeding process by grabbing by a truss robot and matching with the lifting of a hydraulic lifting roller table.

The basic process of feeding the raw materials is generally that a forklift places the raw material large plate stack code at a feeding ground roller, the feeding ground roller sends the raw material large plate stack code into a hydraulic lifting roller table, the hydraulic lifting roller table lifts the raw material large plate stack code to a working height, a truss robot grabs a large plate on the top of the raw material large plate stack code and transfers the large plate to a conveying line at a process inlet end, the conveying line sends the large plate into process equipment, and then the large plate is sequentially grabbed by the hydraulic lifting roller table and the truss robot through successive lifting, so that the feeding process of the raw material large plate stack code is completed.

In this process, there are 4-point deficiencies, which are:

firstly, because the big boards in the stacking are closely stacked, and the heavy pressure generated by the big boards makes the big boards almost have no gap and air, in the grabbing process of the truss robot, the phenomenon that the first big board is grabbed and the second or even the third big board is grabbed often occurs, the phenomenon can cause the big boards to be randomly ejected in an uncontrolled manner, the damage of the big boards of raw materials is directly caused, and the increase of production cost is brought to enterprises.

Secondly, there are many enterprises that have set up a corner-lifting mechanism on the truss robot gripper, and its function is to lift up a corner of the large board at the moment before the truss robot gripper lifts the large board. This approach can only solve the problem of adhesion of the raw material plates with smaller sizes, such as raw material plates with a length and a width of 1000mm X1000mm, but for raw material plates with a length and a width of 1500mm X1000mm or 2000mm X1000mm, the adhesion phenomenon still cannot be avoided because the contact and bonding area of 2 raw material plates with large sizes is too large, and the local tilt angle cannot provide enough clearance and air between the whole large plates.

Thirdly, the corner-lifting mechanism is arranged on the gripper of the truss robot, so that the corner-lifting action and the large board lifting action are executed serially, and the serial execution means that the corner-lifting action is executed first and then the lifting action is executed when the gripper of the truss robot completely adsorbs the large board, so that the original feeding efficiency is reduced.

Fourthly, the frequency of the adhesion phenomenon of the large plates is increased along with the increase of the grabbing speed of the truss robot, so that in order to balance production efficiency and production cost, an enterprise has to reduce the feeding speed, and the grabbing speed of each truss robot can only be set to 7 pieces per minute at most at present.

Fifth, because the carried large board flies out in an uncontrolled and random manner, the large board itself or the flying broken board pieces generated after the large board falls may cause unpredictable damage to nearby workers, which threatens the health and safety of the workers and is not beneficial to the production safety management of enterprises, and in extreme cases, serious safety accidents may occur.
