Description

Technical Field

[0001] This utility model relates to the field of material handling technology, and in particular to a sheet material handling device. Background Technology

[0002] In the picking and feeding of sheet materials, parallelogram mechanisms are commonly used. The active linkage makes a semi-circular motion to send the sheet material from one point (one end of the semi-circular arc) to another point. However, the material at the starting point is often multi-layered. As the material decreases, the position of the starting point will keep changing. Since the picking stroke is fixed, the ending position will also change, resulting in the material being uneven after handling and needing to be rearranged.

[0003] The current conventional approach uses two sets of cross-shaped linear guides to mount a cam bearing, which is then placed within a groove on a predetermined trajectory. A rotating rocker arm, also with radial grooves, is added at the center of the trajectory. The cam bearing is also placed within its groove. The rotation of the rocker arm achieves the predetermined trajectory of the cam bearing. While this structure can achieve the desired trajectory, it requires two sets of linear guides, as well as grooves for fixing the trajectory and rocker arm. These grooves require lubrication, necessitating frequent maintenance and causing environmental pollution. It is also costly and complex. To accommodate materials with varying heights across multiple layers, an additional vertical linear motion mechanism is needed, further increasing costs. Therefore, a new type of material handling device is urgently needed. Utility Model Content

[0004] The purpose of this invention is to provide a sheet material handling device to solve the problem that existing material handling devices mentioned in the background art are costly, complex in design, and unable to handle the handling of multi-layer sheet materials.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sheet material handling device, comprising a support plate, a longitudinal plate fixedly connected to the top surface of the support plate, two synchronous wheels rotatably connected to one side of the longitudinal plate, a driving device for driving the synchronous wheels to rotate on the other side of the longitudinal plate, a synchronous belt rotatably connecting the two synchronous wheels, a swing arm fixedly connected to one side of each of the two synchronous wheels, a detachable hinge shaft at the end of each of the two swing arms away from the synchronous wheels, a connecting rod rotatably connected to the end of each of the two hinge shafts away from the swing arms, a suction cup bracket that can be translated along the bottom surface of the connecting rod, a limit baffle fixedly connected to one end of the longitudinal plate, a blocking device fixedly connected to one end of the suction cup bracket, the blocking device being able to slide vertically along the limit baffle, a reset device for pulling back the suction cup bracket at the end of the suction cup bracket away from the limit baffle, a connecting plate fixedly connected to the end of the suction cup bracket away from the limit baffle, and a suction cup for adsorbing sheet materials fixedly connected to one end of the connecting plate.

[0006] Preferably, the driving device includes a stepper motor fixed to one side of the longitudinal plate, and the output end of the stepper motor passes through the longitudinal plate and is fixedly connected to one side of one of the synchronous pulleys.

[0007] Preferably, one end of the swing arm has a slot, one end of the hinge shaft is engaged in the slot, and one end of the swing arm is threaded with a tightening bolt for adjusting the inner diameter of the slot.

[0008] Preferably, the bottom end of the connecting rod is fixedly connected to a guide rail, and the top surface of the suction cup bracket is fixedly connected to two sliders that are locked in the grooves of the guide rail.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides, for example Figure 1-4The illustrated sheet material handling device includes a support plate 1, a longitudinal plate 2 fixedly connected to the top surface of the support plate 1, two synchronous pulleys 3 rotatably connected to one side of the longitudinal plate 2, and a drive device for driving the synchronous pulleys 3 to rotate on the other side of the longitudinal plate 2. A synchronous belt 4 rotatably connects the two synchronous pulleys 3 together. A swing arm 5 is fixedly connected to one side of each of the two synchronous pulleys 3. A detachable hinge shaft 51 is provided at the end of each swing arm 5 away from the synchronous pulley 3. A connecting rod 6 rotatably connects the ends of the two hinge shafts 51 away from the swing arm 5 together. The bottom surface is provided with a suction cup bracket 7 that can be moved along the bottom surface of the connecting rod 6. One end of the longitudinal plate 2 is fixedly connected to a limit baffle 10. One end of the suction cup bracket 7 is fixedly connected to a blocking device. The blocking device can slide vertically along one side of the limit baffle 10. The end of the suction cup bracket 7 away from the limit baffle 10 is provided with a reset device for pulling back the suction cup bracket 7. The end of the suction cup bracket 7 away from the limit baffle 10 is fixedly connected to a connecting plate 8. One end of the connecting plate 8 is fixedly connected to a suction cup 81 for adsorbing sheet materials.

[0019] When the swing arm 5 swings, it drives the hinge shaft 51 to swing. The swing of the hinge shaft 51 drives the connecting rod 6 to move. The connecting rod 6 drives the suction cup bracket 7 to move. When the suction cup bracket 7 moves to the top surface of the limiting baffle 10, the limiting baffle 10 restricts the movement of the suction cup bracket 7, causing the suction cup bracket 7 to move down along one side of the limiting baffle 10, thereby driving the connecting plate 8 to move down, so that the suction cup 81 is always adsorbed at the fixed position of the sheet material.

[0020] like Figure 1 As shown, the driving device includes a stepper motor 11 fixed to one side of the longitudinal plate 2, and the output end of the stepper motor 11 passes through the longitudinal plate 2 and is fixedly connected to one side of one of the synchronous pulleys 3.

[0021] like Figure 1 and Figure 3 As shown, one end of the swing arm 5 has a slot 52, and one end of the hinge shaft 51 is engaged in the slot 52. One end of the swing arm 5 is threaded with a tightening bolt 53 for adjusting the inner diameter of the slot 52. By loosening the tightening bolt 53, the hinge shaft 51 can be easily removed from the slot 52, which facilitates the replacement and maintenance of the hinge shaft 51.

[0022] like Figure 1 As shown, a guide rail 61 is fixedly connected to the bottom end of the connecting rod 6, and two sliders 71 are fixedly connected to the top surface of the suction cup bracket 7. The sliders 71 are locked on the guide rail 61, which facilitates the sliding of the sliders 71 on the guide rail 61, thereby facilitating the sliding of the suction cup bracket 7 along the guide rail 61.

[0023] like Figure 1As shown, the blocking device includes a cam bearing 9 fixedly connected to the top of the suction cup bracket 7, and the bearing surface of the cam bearing 9 is in rolling connection with the limiting baffle 10.

[0024] like Figure 4 As shown, the reset device includes a pin 12, which is inserted into the inside of the guide rail 61. A fixing rod 13 is fixedly connected to the top surface of the suction cup bracket 7. A spring 14 is fixedly connected between the pin 12 and the fixing rod 13. When the swing arm 5 swings to the leftmost position, the spring 14 is under tension and can pull the cam bearing 9 at one end of the fixing rod 13 to abut against the limit baffle 10 to move, thus preventing the suction cup 81 from changing its adsorption position.

[0025] The working principle of this utility model is as follows: In use, the stepper motor 11 is first started. The output of the stepper motor 11 rotates, driving one of the synchronous pulleys 3 to rotate. This synchronous pulley 3, via the synchronous belt 4, drives the other synchronous pulley 3 to rotate synchronously, causing the two swing arms 5 to swing synchronously. The swing arms 5 drive the hinge shaft 51 to swing, which in turn drives the connecting rod 6 to move. The connecting rod 6 then drives the guide rail 61 to move, which in turn drives the slider 71 to move. Finally, the slider 71 drives the suction cup bracket 7... When the suction cup bracket 7 moves to the leftmost end, the limiting baffle 10 restricts the movement of the cam bearing 9. At the same time, the swing arm 5 swings continuously to the left, causing the cam bearing 9 to move downward along the limiting baffle 10. This causes the suction cup bracket 7 to drive the connecting plate 8 to move downward. The downward movement of the connecting plate 8 allows the bottom of the suction cup 81 to adsorb the material. After adsorption is complete, the stepper motor 11 swings in the opposite direction, causing the material adsorbed at the bottom of the suction cup 81 to move to the rightmost end for the sheet material to be lowered and piled up.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
