Plate overturning machine and numerical-control cutting production line thereof

Abstract

A plate overturning machine comprises an equipment machine frame. An overturning mechanism and a conveying mechanism are arranged on the equipment machine frame. The overturning mechanism comprises anoverturning arm, one or more suction disk assemblies and an overturning drive assembly. One side of the overturning arm is rotationally connected with the equipment machine frame. The suction disk assemblies are assembled on the overturning arm. The overturning drive assembly is arranged on the equipment machine frame and drives the overturning arm to conduct reciprocating overturning between thecorresponding numerical-control cutting machine and the equipment machine frame where the overturning arm is located so that a plate-shaped workpiece on the numerical-control cutting machine can be overturned and placed on a feeding area of the equipment machine frame. The conveying mechanism is located in the feeding area of the equipment machine frame and comprises a conveying chain and a conveying drive assembly, wherein the conveying chain is provided with a stop block, the conveying drive assembly is arranged on the equipment machine frame and drives the conveying chain to operate, and the stop block moves along with the conveying chain and drives the plate-shaped workpiece in the feeding area to be conveyed in the direction of the corresponding numerical-control cutting machine. Theplate overturning machine has the advantages of being reliable and stable in performance, high in overturning efficiency, low in labor intensity and capable of achieving multi-machine combination.

Description

technical field [0001] The invention relates to a sheet material processing production equipment and system, in particular to a sheet material turning machine and a numerical control cutting production line thereof. Background technique [0002] Existing CNC cutting machines generally can only process one side of the plate workpiece. If the plate workpiece needs to be processed on both sides, it is necessary to arrange workers to flip the plate workpiece. When the plate workpiece is large in size or heavy in weight, The operation of the workers is very troublesome and requires a lot of physical strength. In the long run, the labor intensity of the workers is very high, and the operation efficiency of manually turning over the plate workpiece is low. It is difficult to locate the position after each turning, which affects its processing quality; For this reason, in response to this problem, different turning devices have gradually appeared on the market, such as: Chinese pate...

[0002] Existing CNC cutting machines generally can only process one side of the plate workpiece. If the plate workpiece needs to be processed on both sides, it is necessary to arrange workers to flip the plate workpiece. When the plate workpiece is large in size or heavy in weight, The operation of the workers is very troublesome and requires a lot of physical strength. In the long run, the labor intensity of the workers is very high, and the operation efficiency of manually turning over the plate workpiece is low. It is difficult to locate the position after each turning, which affects its processing quality; For this reason, in response to this problem, different turning devices have gradually appeared on the market, such as: Chinese patent document CN106743423A disclosed a composite plate turning machine on May 31, 2017, and specifically disclosed: including: an upper frame, a lower frame , chain, connecting rod, plate clamping frame, pulley platform, motor, infrared sensor, PLC control system; the shell is a net column structure, and the water outlet is set at the bottom of the shell; the lower frame is directly set on any part of the production line Below the roller conveying mechanism, the direction is parallel to the axial direction of the roller. The middle of the lower frame is a hollow structure. The midpoint of the hollow position in the horizontal direction is provided with a power sprocket, and the left and right sides of the power sprocket in the horizontal direction are respectively provided with a lower frame sprocket. 1 and the lower frame sprocket 2, the lower frame sprocket 3 and the lower frame sprocket 4 are respectively set under the left and right sides of the power sprocket; the upper frame is an inverted U-shaped hollow frame, and the upper frame is set in contact with the lower frame The upper part of the lower frame is stored, the horizontal direction of the upper frame is parallel to the lower frame, and the vertical direction is perpendicular to the axial direction of the roller. The inner diameter of the upper frame is larger than the width of the roller frame. Two upper frame sprockets, the upper frame sprockets opposite the two inner walls are hollow without connection; the motor is connected to the power sprocket, and the motor provides power for the chain movement; the spindle tension is set on the upper frame chain Wheel and power sprocket, lower frame sprocket 1, lower frame sprocket 2, the chain is sandwiched by lower frame sprocket 3, lower frame sprocket net and power sprocket; one end of the connecting rod is located on the upper frame One side of the chain is connected to a sleeve shaft and is clamped by the limit piece. The connecting rod can rotate around the cylindrical surface of the sleeve; The shaft rotates; the structure of the plate clamping frame is a plurality of small rectangular frame bodies with a width smaller than the gap between the idlers and the same size. A vertical longitudinal connecting rod b is respectively arranged in the middle of the left and right sides of the same size. A large rectangular frame body connected in series with small rectangular frame bodies, one side of the small rectangular frame body a in the middle is provided with a circular arc transition surface, and the other side is provided with a connecting shaft; the plate clamping frame is placed between the production line and the idler roller In the gap between two supporting rollers whose axes are parallel to each other, the small rectangular frame body a in the middle of the plate clamping frame is supported on the pulley platform; the pulley platform is placed on the top surface of the lower frame, under the bottom surface of the small rectangular frame body a, the pulley There are several pulleys on the top surface of the platform, and the height of the pulley platform is adjustable. By adjusting the height of the pulley platform, the height of the bottom surface of the plate clamping frame is slightly lower than the top surface of the roller on the roller conveyor table; the infrared sensor is set on the top of the upper frame Inside; the PLC control system is set in the hollow position of the lower frame to control the whole units running

The flipping machine uses the technical solution of in-situ flipping to flip the plate, and the flipped plate is directly returned to the CNC cutting machine for further processing. The structure is complex and the manufacturing cost is high, and it can only be applied to a single CNC cutting machine.
