Description

Technical Field

[0001] The present application relates to the technical field of plate stacking, and in particular to a plate blanking and stacking device. Background Art

[0002] In the sheet metal processing industry, a system combining a vacuum suction cup rack and a crane is currently widely used to efficiently unload the processed sheets from the rack and transfer them to a designated location, where they are stacked and stored horizontally. However, in actual operation, this stacking method, especially when it comes to stacking large-sized sheets, encounters a more difficult technical problem: air layers are easily mixed between the sheets, which has a significant impact on the stacking stability.

[0003] Specifically, during the parallel stacking process, the existence of these air layers greatly reduces the friction between the plates, making it easy for the stacked plates to shift relative to each other. In addition, during the stacking process, as the pressure between the plates increases, the air may be compressed or even discharged. This dynamic change further exacerbates the sliding tendency of the plates. This plate displacement phenomenon caused by air factors not only affects the neatness and aesthetics of the stacking, but may also pose a potential threat to the subsequent processing, transportation and storage safety of the plates. Summary of the invention

[0004] In order to reduce the amount of air trapped between plates, the present application provides a plate blanking and stacking device.

[0005] The present application provides a plate blanking and stacking device, which adopts the following technical solution: A plate material unloading and stacking device comprises a stacking rack and a control component for controlling the lifting and translation of the stacking rack; the stacking rack comprises: a ceiling panel, which is controlled by the control component and performs lifting and translation movements; a movable suction cup rack, which is arranged below the ceiling panel, and a plurality of vacuum suction cup groups are installed on the movable suction cup rack; a connecting component, which is used to connect the ceiling panel and the movable suction cup rack so that the movable suction cup rack can switch between an inclined state and a horizontal state; wherein the connecting component comprises a connecting rack and a rope reel group, the connecting rack is vertically connected to the ceiling panel, and one end of the connecting rack is hinged to one end of the movable suction cup rack; the rope reel group is installed on the ceiling panel, and the rope reel group comprises a pull rope and a rope reeling machine for reeling in or releasing the pull rope, and one end of the pull rope is fixedly connected to one end of the movable suction cup rack away from the connecting rack; the reeling of the pull rope causes one end of the movable suction cup rack to rotate and tilt around the connecting rack.

[0006] By adopting the above technical solution, the stacking rack and the control component are set to achieve accurate stacking of the plates. The ceiling board of the stacking rack is controlled by the control component to perform lifting and translational movements, and a plurality of vacuum suction cup groups are installed on the movable suction cup rack, which can effectively adsorb the plates. The connecting component enables the movable suction cup rack to switch between the inclined and horizontal states, and the inclination angle of the movable suction cup rack is controlled by winding or releasing the pull rope of the rope reel group. When releasing the plate, the movable suction cup rack can be tilted at a certain angle, so that the plate adsorbed in the non-horizontal state can be first attached to the plate in an inclined posture on one side, and then gradually attached on the other side. The air layer is discharged by the gradual release after tilting, avoiding the direct parallel attachment of the plates, reducing the possibility of the air layer being closed, and reducing the air residue between the plates. In addition, the pull rope connection point and the hinged end are respectively located at the two ends of the movable suction cup rack, so that the movable suction cup rack will form an outward arch deformation and push the plate to form a corresponding deformation, thereby better squeezing out the air.

[0007] Optionally, the connecting frame includes two parallel hinged rods and a connecting rod fixedly connecting the two hinged rods; the two hinged rods vertically pass through the ceiling board and are respectively hinged to both sides of one end of the movable suction cup frame; the connecting rod is located above the ceiling board for limiting.

[0008] By adopting the above technical solution and arranging two parallel hinged rods and a connecting rod, the stability and reliability of the movable suction cup frame during movement are ensured.

[0009] Optionally, the rope collecting machine is fixed to a side of the ceiling panel close to the movable suction cup frame, and a first through hole for the pull rope to pass through is opened on the ceiling panel, and the first through hole is located above the connection between the pull rope and the movable suction cup frame.

[0010] Optionally, the connecting frame also includes a winding rod parallel to the connecting rod, and the two ends of the winding rod are respectively fixedly connected to two hinged rods; the connecting rod and the winding rod limit to form two hinged rod sliding distances; the ceiling plate is also provided with a second through hole for the pull rope to pass through, and the second through hole is located at the position of the connecting frame; the pull rope passes through the second through hole, goes around the bottom of the winding rod and then passes through the second through hole, and then passes through the first through hole to connect with the movable suction cup frame.

[0011] By adopting the above technical solution, by bypassing the pull rope around the rod, the hinged end of the movable suction cup frame can be lifted upward during the process of winding the pull rope, so that the plate adsorbed on the movable suction cup frame can be tilted and lifted, so that when collecting the plate, there is no need to lift or lower it, and it can be directly moved horizontally.

[0012] Optionally, a rope wheel is mounted on the winding rod, and the pull rope is located in the rope wheel.

[0013] By adopting the above technical solution, the winding and releasing of the pull rope are made more labor-saving, thereby extending the service life of the rope.

[0014] Optionally, the pull rope is located at a fixed limiting ball in the lower part of the first through hole, and the diameter of the limiting ball is larger than the first through hole; when the winding rod is in contact with the ceiling panel and the movable suction cup frame is in contact with the limiting ball, the movable suction cup frame is in an inclined state, and the distance between the hinged end of the movable suction cup frame and the ceiling panel is greater than the distance between the other end of the movable suction cup frame and the ceiling panel.

[0015] By adopting the above technical solution, the accurate position of the movable suction cup frame in the tilted state is ensured, and excessive tilting or deviation is prevented, thereby improving the placement accuracy and stability of the plates during the stacking process.

[0016] Optionally, another limiting ball is fixed to the portion of the pull rope located above the first through hole; when the pull rope is released until the limiting ball blocks the first through hole and the connecting rod and the ceiling plate are in contact, the movable suction cup frame is in a horizontal state.

[0017] By adopting the above technical solution, the mechanical locking of the inclined state (the limiting ball abuts against the first through hole) and the horizontal state (the other limiting ball blocks the first through hole) ensures the safety of the stacking process.

[0018] Optionally, the first through hole and the second through hole are in a square structure and are provided with arc chamfers.

[0019] By adopting the above technical solution, the pull rope can pass through the through hole more smoothly, reducing friction and wear.

[0020] In summary, the present application includes at least one of the following beneficial effects: 1. Significantly reduce the amount of air trapped when stacking sheets, improving friction and stability; 2. Mechanical locking of tilted and horizontal states ensures the safety of the stacking process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The present application is further described in detail below in conjunction with the accompanying drawings.

[0024] The application discloses a plate blanking and stacking device.

[0025] Reference Figure 1 The stacking device includes a stacking frame 1 and a control component 2. The stacking frame 1 is used to grab and release the plates, while the control component 2 is responsible for controlling the lifting and translation movement of the stacking frame 1 so that the processed plates can be transported to the corresponding stacking area. Reference Figure 1 , 2 The stacking rack 1 includes a ceiling panel 3, a movable suction cup rack 4 and a connecting assembly 6. The ceiling panel 3 is a basic component of the stacking rack 1. The ceiling panel 3 is controlled by the control assembly 2 and can perform stable lifting and translation movements to provide power support and movement guidance for the entire stacking process.

[0026] The movable suction cup frame 4 is arranged below the ceiling board 3, and a plurality of vacuum suction cup groups 5 are installed thereon. These vacuum suction cup groups 5 can effectively absorb the plate to realize the grabbing and releasing of the plate.

[0027] The connecting assembly 6 is used to connect the ceiling panel 3 with the movable suction cup frame 4, and can switch the movable suction cup frame 4 between an inclined state and a horizontal state.

[0028] The lifting structure of the control component 2 can be driven by a hydraulic or pneumatic cylinder, and the extension and retraction action of the hydraulic or pneumatic cylinder is utilized to directly push the ceiling plate 3 to move up and down.

[0029] The translation structure of the control component 2 can be driven by a synchronous belt or chain, and the synchronous belt wheel is driven by a motor to rotate, and the synchronous belt is connected to the lifting structure to drive the stacking rack 1 to move horizontally along the guide rail. In other embodiments, the lifting and translation functions in the control component 2 can also be combined with other mechanisms such as screw rods, linear motors, etc., which are not limited in the embodiments.

[0030] Reference Figure 2 , 3 Specifically, the connection assembly 6 includes a connection frame 7 and a rope reel 8. The connection frame 7 includes two parallel hinged rods 9 and a connection rod 10 fixedly connecting the two hinged rods 9. The connection rod 10 is fixed to the upper end of the hinged rod 9, and the connection rod 10 is located above the ceiling board 3 to play a limiting role. The two hinged rods 9 vertically pass through the ceiling board 3 and are respectively hinged to the two sides of one end of the movable suction cup frame 4.

[0031] The connecting frame 7 further comprises a winding rod 11 parallel to the connecting rod 10, and both ends of the winding rod 11 are respectively fixedly connected to the two hinged rods 9. The connecting rod 10 and the winding rod 11 are limited to form a sliding distance of the two hinged rods 9.

[0032] Reference Figure 3 , 4 The rope reel 8 is installed on the ceiling board 3, and includes a pull rope 13 and a rope take-up machine 12. The rope take-up machine 12 is used to reel in or release the pull rope 13, and the rope take-up machine 12 is fixed on a side of the ceiling board 3 close to the connecting frame 7. One end of the pull rope 13 is fixedly connected to the end of the movable suction cup frame 4 away from the connecting frame 7.

[0033] Further, see Figure 3 , 4 The ceiling plate 3 is provided with a first through hole 14 for the pull rope 13 to pass through, and the first through hole 14 is located above the connection between the pull rope 13 and the movable suction cup frame 4. The ceiling plate 3 is also provided with a second through hole 15 for the pull rope 13 to pass through, and the second through hole 15 is located at the connection frame 7. After the pull rope 13 is led out from the rope collecting machine 12, it passes through the second through hole 15, passes around the bottom of the winding rod 11, and then passes out of the second through hole 15 and passes through the first through hole 14 to connect with the movable suction cup frame 4.

[0034] Reference Figure 2 , 3 A limiting ball 17 is fixed to the lower part of the pull rope 13 located at the first through hole 14, and the limiting ball 17 has a diameter larger than the first through hole 14. When the winding rod 11 contacts the ceiling board 3 and the movable suction cup frame 4 contacts the limiting ball 17, the movable suction cup frame 4 is in an inclined state, and the distance between the hinged end of the movable suction cup frame 4 and the ceiling board 3 is greater than the distance between the other end of the movable suction cup frame 4 and the ceiling board 3.

[0035] In addition, another stop ball 17 is also fixed to the portion of the pull rope 13 above the first through hole 14. When the pull rope 13 is released until the stop ball 17 blocks the first through hole 14 and the connecting rod 10 abuts against the ceiling plate 3, the movable suction cup frame 4 is in a horizontal state. That is, the two stop balls 17 form a movable space for the pull rope 13.

[0036] Reference Figure 3 In order to make the winding and releasing of the pull rope 13 more labor-saving and prolong the service life of the rope, a rope wheel 16 is mounted on the winding rod 11, and the pull rope 13 is located in the rope wheel 16. At the same time, the first through hole 14 and the second through hole 15 are square structures and are provided with arc chamfers.

[0037] The implementation principle of a plate material stacking device in the embodiment of the present application is as follows: When the plate stacking operation is required, the control component 2 drives the stacking frame 1 to move above the plate area to be taken. The movable suction cup frame 4 is kept horizontal under the action of the connecting component 6, and the vacuum suction cup group 5 on it is aligned with the plate surface. Then, the vacuum suction cup group 5 is started to generate sufficient suction force to firmly adsorb the plate.

[0038] After the adsorption is completed, the rope retracting machine 12 starts to reel in the draw rope 13. The reeling in of the draw rope 13 causes one end of the movable suction cup frame 4 to rotate and tilt around the connecting frame 7. As the movable suction cup frame 4 tilts, the adsorbed sheet also tilts. At the same time, the tilted movable suction cup frame 4 also lifts up a distance, so that the sheet leaves the processing area.

[0039] Then, the control component 2 drives the stacking frame 1 to move to the top of the plate to be stacked, the control component 2 is lowered close to the lower stacking plate, and the rope collecting machine 12 releases the pull rope 13, so that one side of the plate first contacts the plate or stacking base that has been stacked below, and the other side gradually fits. During the bonding process, the air layer between the plates is discharged through the gradual release after tilting, which effectively avoids the closure of the air layer and reduces the amount of residual air between the plates. Finally, the vacuum suction cup group 5 stops adsorption, and the stacking frame 1 returns to the initial position under the drive of the control component 2, ready for the next round of plate stacking operation.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
