Description

Technical Field

[0001] This utility model relates to the technical field of thin sheet material production equipment, specifically a thin material clamping system. Background Technology

[0002] In production practice, thin, sheet-like materials, such as printed materials, packaging bags, and paper, are fed from the front-end conveyor line to the receiving platform and stacked. Once a certain quantity is stacked, the gripper unit holds the stack and transports it to the bundling station for bundling before further transfer. In existing technology, the receiving platform is typically designed as an open platform, which is not only simple and low-cost but also convenient for the gripper unit to handle materials. However, for long and slender materials, especially those heat-sealed in the middle, a larger stack often results in a lower center and higher sides, making it prone to tipping over on the open receiving platform, affecting subsequent operations. Furthermore, even if the material doesn't tip over during the initial stacking, the friction between the gripper unit holding and pressing one end of the stack can cause the other end to bulge outwards, affecting subsequent bundling operations and compressing the material. Utility Model Content

[0003] This utility model discloses a thin material clamping system, which solves the technical problems in the prior art where stacked materials are easy to tip over and difficult to clamp, and the poor flatness of the stacked materials during clamping affects subsequent bundling. It has the technical advantages of reasonable structure, convenient clamping, and ensuring the flatness of stacked materials for easy subsequent bundling. The technical solution adopted is as follows: A thin material gripping system includes a gripper unit comprising an upper gripping arm, a lower gripping arm, and a gripping drive. The gripping drive can cause the upper and lower gripping arms to open and close to grip or release material. The gripper unit is designed such that when the gripper unit grips the first end of the material from the receiving platform, the second end of the material remains in the channel between two adjacent vertical baffles on the receiving platform.

[0004] Based on the above technical solution, the gripper unit moves back and forth to grip the material from the receiving platform, and the gripper unit extends into the channel between the two vertical baffles to grip the first end of the material.

[0005] Based on the above technical solution, the receiving platform is designed to transport the first end of the material in the channel to between the upper clamping arm and the lower clamping arm, so as to facilitate the gripper unit to clamp the first end of the material.

[0006] Based on the above technical solution, the distance between the side edge of the gripper unit and the adjacent baffle is 1~10mm.

[0007] Based on the above technical solution, the gripper unit further includes a fixed stop portion, which avoids the upper gripping arm and / or the lower gripping arm, and the stop portion can laterally abut against the material to regulate the material.

[0008] Based on the above technical solution, when the gripper unit moves back and forth to pick up materials from the receiving platform, and the gripper unit extends into the channel between the two vertical baffles to pick up the first end of the material, the gripper unit extends from the entrance end of the channel into the channel to pick up the material, and a stop is fixed on the inner wall of the channel near the exit end of the channel to limit the forward movement of the material.

[0009] The channel is multiple and is set up one-to-one with the material conveying channel on the upstream conveying unit.

[0010] Based on the above technical solution, the receiving platform includes a material support unit for receiving materials, and the material support unit is designed to be movable above the lower clamping arm to facilitate the gripper unit to clamp the materials.

[0011] Based on the above technical solution, the receiving platform also includes a material support drive corresponding to the material support unit, and the material support unit can be raised and lowered under the action of the material support drive.

[0012] Based on the above technical solution, the material support unit includes several support rods that extend forward and backward and are arranged side by side at intervals. Preferably, when the gripper unit moves forward and backward to pick up material from the receiving platform, and the gripper unit extends into the channel between the two vertical baffles to pick up the first end of the material, the support rod is designed such that the first end of the support rod retracts into the channel, and extends out of the first end of the support rod when the material falls, so as to facilitate the gripper unit to extend into the channel to pick up the material.

[0013] Based on the above technical solution, the ends of the upper clamping arm 1 and / or the lower clamping arm 1 include inclined surfaces to guide materials into the space between the upper clamping arm and the lower clamping arm 1.

[0014] Based on the above technical solution, a binding unit is also included, which is located near the channel. The binding unit is designed to bind the material after the gripper unit has grasped the material and partially or completely removed the material from the channel.

[0015] Beneficial effects This utility model has a reasonable design. The gripper unit is designed such that when the gripper unit clamps the first end of the material from the receiving platform, the second end of the material remains within the channel between two adjacent vertical baffles on the receiving platform. In this way, firstly, the material falls between the two baffles before being gripped, preventing tipping even when multiple materials are stacked, facilitating gripping by the gripper unit. Secondly, when the gripper clamps the first end of the material, the second end remains within the channel between the two baffles. When the materials being gripped and stacked interact and shift laterally, the two baffles can straighten the stacked materials, ensuring good flatness on the sides of the resulting stack, facilitating subsequent bundling and packaging operations, and promoting stable and continuous production.

[0016] In this utility model, the gripper unit also includes a fixed stop. When the upper and lower gripping arms move from the open state to the closed state, they cooperate with the baffle, and the stop can abut against the material to neatly arrange the stacked material in the length direction. This can further improve the flatness of the stacked material, facilitate subsequent bundling and packaging, and help improve the pass rate after bundling.

[0017] In this invention, before gripping the material, the material-supporting unit of the receiving platform is slightly higher than the lower clamping arm. This facilitates the easier entry of the head of the stacked material between the upper and lower clamping arms. Furthermore, it includes a material-supporting drive that drives the material-supporting unit to move up and down, thus facilitating the receipt of material from the upstream conveying unit. In addition, when the gripper unit moves back and forth to grip the material from the receiving platform, and the gripper unit extends into the channel between the two vertical baffles to grip the first end of the material, the support rod in the material-supporting unit can be designed such that the support rod supports the stacked material, with its head retracting into the channel and extending beyond the head of the support rod when the material falls. This facilitates the gripper unit's insertion into the channel to grip the material, demonstrating a clever design. Attached Figure Description

[0024] like Figures 1-4 The thin material gripping system shown includes a gripper unit 1. The gripper unit 1 is a prior art technology, as described in this embodiment. Figure 3 As shown, the gripper unit 1 includes an upper gripping arm 11, a lower gripping arm 12, and a gripping drive. The gripping drive can drive the upper gripping arm 11 and the lower gripping arm 12 to open and close, so as to grip or release materials.

[0025] The gripper unit 1 is designed such that when the gripper unit 1 clamps the first end of the material from the receiving platform 2, the second end of the material remains in the channel 100 between two adjacent vertical baffles 3 on the receiving platform 2. Specifically, when the gripper unit 1 moves back and forth to clamp the material from the receiving platform 2, the gripper unit 1 extends into the channel 100 between two adjacent vertical baffles 3 on the receiving platform 2 to clamp the material. When the upper clamping arm 11 and the lower clamping arm 12 close and clamp the stacked material, the material interacts with each other under the action of the clamping force, causing the material to swing left and right and be regulated by the baffles 3 on both sides, thus making the side of the stacked material after clamping flat.

[0026] like Figure 3 As shown, the gripper unit 1 also includes a fixed stop 3. In this embodiment, the lower gripping arm 12 is fixedly installed, and the gripping drive drives the upper gripping arm 11 to swing to achieve opening and closing, gripping or releasing materials. The stop 13 is generally vertically installed and fixed on the lower gripping arm 11. The stop 13 is provided with a clearance part to avoid the upper gripping arm 11, so as to avoid interference. During the process of the upper gripping arm 11 and the lower gripping arm 12 gripping the material, the stop 13 can abut laterally with the end of the material to straighten the front end of the material. In addition, the stop 13 cooperates with the two baffles 3 to straighten the stacked materials on three sides at the same time, which is beneficial to further improve the straightening effect of the two baffles 3 on the material.

[0027] In this embodiment, to allow for larger processing errors and to avoid the clamping arm from colliding with the baffle 3 due to vibration during operation, the distance between the side edge of the gripper unit 1 and the adjacent baffle 3 is 1~10mm. In other embodiments of this utility model, this distance can be even greater while meeting the clamping requirements.

[0028] Furthermore, the gripper unit 1 is designed to extend into the channel 100 from the inlet end to grip the material, and a stop block is fixed on the inner wall of the channel 100 near the outlet end to limit the forward displacement of the material 1. In this embodiment, the stop block 3 is plate-shaped and fixed to the baffle plate 3 by multiple countersunk screws.

[0029] In this embodiment, multiple gripper units 1 and channels 100 are provided, each corresponding to a material conveying channel on the upstream conveying unit. This allows for matching multiple conveying channels of the upstream conveying unit, improving production efficiency. Accordingly, each channel 100 is formed by the space between two adjacent baffles 3.

[0030] The receiving platform 2 includes a material receiving unit 21, such as... Figure 1 As shown, the material support unit 21 includes several support rods 211 that extend forward and backward and are arranged side by side at intervals. The material support unit 21 is designed to be located above the lower clamping arm 12 before the gripper unit 2 extends into the channel 100 to grip the material.

[0031] In addition, the receiving platform 2 also includes a material-supporting drive 22 corresponding to the material-supporting unit 21, which can move up and down under the action of the material-supporting drive 22. Thus, when the material-supporting drive 22 causes the material-supporting unit 21 to move upwards and approach the upstream conveying unit, it can conveniently receive materials transported from the conveying unit. When the material-supporting drive 22 causes the material-supporting unit 21 to move downwards and be positioned above the lower clamping arm 12, it facilitates the entry of stacked materials into the space between the upper clamping arm 11 and the lower clamping arm 12, allowing the gripper unit 1 to clamp the materials within. This allows for material transfer and convenient, flexible arrangement of the upstream conveying unit and the gripper unit 1.

[0032] like Figure 2 As shown, the support rod 211 is designed such that the first end of the support rod 211 is retracted into the channel 100 and extends out of the first end of the support rod 211 when the material is dropped. In this way, when the gripper unit 1 approaches the first end of the support rod 211, the stacked material naturally enters between the upper gripping arm 11 and the lower gripping arm 12, thereby facilitating the gripper unit 1 to extend into the channel 100 to grip the material.

[0033] In this embodiment, the end of the lower clamping arm 12 includes a bevel to guide the material into the space between the upper clamping arm 11 and the lower clamping arm 12. In addition, the head of the material extends into the space between the upper clamping arm 11 and the lower clamping arm 12 for a length of at least 20 mm and is clamped therebetween, resulting in good clamping stability.

[0034] like Figure 4 As shown, it also includes a binding unit 5 located near the channel 100. The binding unit 5 is designed to bind the material after the gripper unit 1 has gripped the material and removed the material partially or completely from the channel 100. The binding unit 5 is prior art and can be selected by those skilled in the art according to their needs, and will not be described in detail here.

[0035] Work process 1) The stacked materials are dropped from the upper support rod 6 onto the support rod 211 of the material support unit 21. Under the action of the support rod drive 22, the support rod 211 is displaced to its lower limit of stroke and placed above the lower clamping arm 12. 2) The gripper unit 1 moves from its initial position and extends into the channel 100. As the gripper unit 1 approaches the head end of the support rod 211, the stacked material portion extends into the space between the upper gripping arm 11 and the lower gripping arm 12. 3) The clamping drive causes the upper clamping arm 11 to flip downward and approach the lower clamping arm 12. As the upper clamping arm 11 moves downward and abuts against the top of the stacked materials, several materials swing left and right under the clamping force of the gripper unit 1. At this time, the baffles 3 on both sides straighten them, and the stop part 13 also straightens the front end of the stacked materials, which helps to enhance the straightening effect of the baffles 3 on the stacked materials.

[0036] 4) The gripper unit 1 grips the stacked materials and moves them out of the channel 100, and the binding unit 5 binds the stacked materials. 5) After the gripper unit 1 continues to transport the bundled material to the output unit 200, it releases the bundled material. 6) The gripper unit is reset to its initial position.

[0037] Example 2 The difference between Embodiment 2 and Embodiment 1 is that, instead of the gripper unit 1 moving back and forth, the receiving platform 2 can transport the first end of the material in the channel 100 to between the upper gripping arm 11 and the lower gripping arm 12, so that the gripper unit 1 can clamp the first end of the material. Specifically, the receiving platform 2 also includes a back-and-forth pushing drive (not shown). When the receiving platform 2 moves above the lower gripping arm 12, the pushing drive can abut against the second end of the stacked material, so that the stacked material slides back and forth along the receiving platform 2, and finally pushes the first end of the stacked material between the upper gripping arm 11 and the lower gripping arm 12 to be clamped by the gripper unit 1, and at this time the second end of the stacked material is still kept in the channel 100.

[0038] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
