AI Technical Summary
Existing depalletizers are inefficient in automated production lines. The robotic arm needs to make multiple reciprocating movements. The position of the material at the top of the stack determines the increase in the vertical stroke of the robotic arm, which leads to a larger distance, affecting the feeding efficiency. In addition, the machine needs to be stopped and re-stacked, resulting in a slow cycle time of the stamping line.
The system employs a lifting column to drive the horizontal beam to slide, combined with a clamping module driven by a servo motor and a cylinder, to achieve automated destacking and loading of sheet metal. The cylinder drives the rotating shaft to rotate, which in turn grips the sheet metal with an arc-shaped rod, improving loading efficiency.
It has enabled automated destacking and loading of sheet materials, improved loading efficiency, reduced the number of movements of the robotic arm, and enhanced the operating efficiency of the production line.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of stacker cranes, and in particular to a destacking machine for both sheet metal and steel plates. Background Technology
[0002] In many automated production lines, material stacking and unloading are required. Taking an automated stamping line as an example, the equipment used for stacking and unloading is a depalletizer. The depalletizer uses a top-stacking and top-unloading method, where the stacked material is placed on the depalletizer manually. A robotic arm with a suction cup then grabs the material pieces from above the depalletizer, lifts them vertically, and moves them horizontally to the working position of the punch press. The robotic arm is located between the depalletizer and the punch press, and it follows a left-down-up-right-down-up-left return motion between the two. One cycle requires seven actions. The position of the material pieces at the top of the stack determines the vertical travel distance of the robotic arm when grabbing the parts. As the number of material pieces increases, the vertical distance between the material pieces at the top of the stack and the robotic arm increases, so the vertical travel distance when the robotic arm grabs the parts needs to be increased. In addition, after all the material stacks on the depalletizer have been picked up, they need to be re-stacked. However, before re-stacking, the stamping line must be stopped and the robot arm must stop picking up materials. After the material stacks on the depalletizer are re-stacked, the stamping line and robot arm are restarted, resulting in a slow stamping line cycle and low efficiency. Utility Model Content
[0003] The purpose of this utility model is to provide a dual-purpose destacking machine for sheet metal to solve the problems existing in the prior art.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0005] A dual-purpose destacking machine for sheet metal includes a lifting column, on which one end of a crossbeam is slidably mounted. The lifting column drives the crossbeam to slide up and down.

[0023] Example 1:
[0024] like Figures 1-3 As shown, a dual-purpose destacking machine for sheet metal includes a lifting column 1, one end of a crossbeam 2 slidably mounted on the lifting column 1, a lifting platform spaced apart on one side of the lifting column 1, and a support panel at the bottom of the lifting column 1. The lifting column 1 is used to drive the crossbeam 2 to slide up and down. Figure 1 As can be seen, the lifting column 1 is a traditional column-type lifting machine, which can drive the crossbeam 2 (boom) to move up and down. The top of the end of the crossbeam 2 away from the lifting column 1 is fixed with a drive motor 3. A crossbar 4 is fixedly installed on the output shaft at the bottom of the drive motor 3. The drive motor 3 is used to make the crossbar 4 rotate circumferentially. The top of the end of the crossbar 4 away from the output shaft of the drive motor 3 is fixedly installed with a servo motor 5. A frame 6 is fixedly installed on the bottom output shaft of the servo motor 5. Clamping modules 7 are symmetrically arranged on the left and right sides of the bottom of the frame 6.
[0025] The clamping module 7 includes a first rotating shaft 71, a second rotating shaft 72, a third rotating shaft 73, a fourth rotating shaft 74, a first cylinder 75, a second cylinder 76, a third cylinder 77, and a fourth cylinder 78. The first rotating shaft 71, the second rotating shaft 72, the third rotating shaft 73, the fourth rotating shaft 74, the first cylinder 75, the second cylinder 76, the third cylinder 77, and the fourth cylinder 78 are all arranged horizontally. The first rotating shaft 71, the second rotating shaft 72, the third rotating shaft 73, and the fourth rotating shaft 74 are respectively rotatably installed at the four bottom corners of the frame 6, and the axial direction of the first rotating shaft 71, the second rotating shaft 72, the third rotating shaft 73, and the fourth rotating shaft 74 is in the front-back direction. One end of the first cylinder 75, the second cylinder 76, the third cylinder 77, and the fourth cylinder 78 are respectively rotatably installed at the four top corners of the frame 6.
[0026] A connecting rod 8 is fitted in the middle of the first rotating shaft 71, the second rotating shaft 72, the third rotating shaft 73, and the fourth rotating shaft 74. The end of the first cylinder 75 that is not connected to the frame 6 is rotatably connected to the connecting rod 8 on the first rotating shaft 71. The end of the second cylinder 76 that is not connected to the frame 6 is rotatably connected to the connecting rod 8 on the second rotating shaft 72. The end of the third cylinder 77 that is not connected to the frame 6 is rotatably connected to the connecting rod 8 on the third rotating shaft 73. The end of the fourth cylinder 78 that is not connected to the frame 6 is rotatably connected to the connecting rod 8 on the fourth rotating shaft 74. Multiple lifting rods are provided on the left and right sides of the bottom of the frame 6. A first ranging grating 10 is fixedly installed at the bottom end of the lifting rod on the left side of the bottom of the frame 6, and a second ranging grating 11 is fixedly installed at the bottom end of the lifting rod on the right side of the bottom of the frame 6. These are used to measure whether the distance between the arc rods 9 on the left and right sides of the main clamping object and the sheet material is consistent.
[0027] The first cylinder 75, the second cylinder 76, the third cylinder 77 and the fourth cylinder 78 are respectively used to drive the first rotating shaft 71, the second rotating shaft 72, the third rotating shaft 73 and the fourth rotating shaft 74 to rotate axially via the connecting rod 8;
[0028] Multiple arc-shaped rods 9 are evenly spaced along the axial direction on the first rotating shaft 71, the second rotating shaft 72, the third rotating shaft 73, and the fourth rotating shaft 74.
[0029] The frame 6 includes a fixed plate 61, a rectangular frame 62, a first linear drive guide rail 63, and a pneumatic slide rail 64. The fixed plate 61 is fixedly connected to the output shaft of the servo motor 5. The first linear drive guide rail 63 is fixedly installed on the bottom rear side of the fixed plate 61, and the pneumatic slide rail is fixedly installed on the bottom front side of the fixed plate 61.

The rectangular frame 62 is fixedly installed on the bottom of the first linear drive guide rail 63, and the top front side of the rectangular frame is fixedly connected to the pneumatic slide rail. The first linear drive guide rail 63 and the pneumatic slide rail 64 are used to cooperate to drive the rectangular frame 62 to move left and right relative to the fixed plate 61. Because the distance between the material stack and the lifting column 1 will have an error within a certain range, the frame itself needs to have a certain displacement of left and right.
[0030] The specific implementation process is as follows: The first, second, third, and fourth rotating shafts are driven by the first, second, third, and fourth cylinders to rotate, so that the first, second, third, and fourth rotating shafts work together in pairs to grasp the board material, realizing automated board destacking and simultaneously dismantling and loading two stacked material stacks, which greatly improves the loading efficiency.
