Description

A plate loading machine

technical field

The invention relates to the technical field of plate processing equipment, in particular to a plate feeder.

Background technique

The board feeding machine is used in conjunction with the board processing equipment. The traditional board feeding machine often sends out more than two boards at a time, which affects the board processing. The invention patent application with the application number 201610172297.9 discloses an automatic sheet material feeding machine, which can prevent more than two sheets from entering the next processing equipment at the same time by setting a hinged baffle plate and a proximity switch at the discharge port However, there are the following disadvantages: (1) Since the channel steel is set above the supporting plate, and the channel steel is equipped with a pushing mechanism, it can only be loaded from the side of the frame body by a forklift, so it cannot be hoisted by a crane The equipment is loaded from the top, while the side loading has the problem that the loading position is not easy to control, which leads to the skewed placement of the plates in the equipment. In addition, in order to save space above the ground and facilitate operation, it is often necessary to bury a part of the equipment. Under the ground, at this time, the material can only be loaded from the top, and the automatic sheet material loading machine is obviously impossible to realize. In addition, when the pallet cannot be stopped due to the failure of the power mechanism and other reasons, the pallet will crush the pushing mechanism; ( 2) The paddle needs to be pushed out of the platform every time before it can be returned to its original position. The stroke of the paddle is long and the feeding efficiency is low; (3) The patent application does not disclose how the height of the pallet rises each time However, if the lift on the pallet is too high, the paddle will push two or more plates at the same time. When two or more plates are sent out at the same time, the equipment will stop. Although it can prevent the wrong quantity of materials from being loaded, the shutdown will affect the efficiency of the entire production line; (4) The automatic plate feeding machine has complex structure, high cost and high noise.
