Description

Technical Field

[0001] The present invention relates to the field of paper bag manufacturing, in particular to a double-independent lifting paper platform loading device. Background Art

[0002] As we all know, paper is a recyclable resource. Papermaking is primarily made from plant fibers. In addition to the three main components of cellulose, hemicellulose, and lignin, it also contains smaller amounts of other components, such as resin and ash. Compared to plastic bags, paper bags are made from trees, a renewable resource. They are also biodegradable and recyclable, making them widely used.

[0003] For the manufacture of some paper bags, it is necessary to splice two sheets of paper and then complete the subsequent paper bag manufacturing process. The existing paper lifting platform simultaneously lifts the papers stacked on both sides to the two suction devices located above for suction, so as to complete the purpose of loading the papers on both sides. Since the number of papers stacked on both sides is not necessarily the same, it is possible that one side has more papers stacked and the other side has fewer papers stacked. When the same paper lifting platform is raised or lowered, the two top sheets of paper are not at the same height and cannot be sucked by the suction devices separately, which cannot meet the production needs.

[0004] Therefore, it is necessary to further develop a dual independent lifting paper table loading device. Summary of the Invention

[0005] The object of the present invention is to provide a dual independent lifting paper table loading device with two stacks of paper adjusted separately, which can ensure that the highest points of the two stacks of paper are aligned.

[0006] In order to achieve the above-mentioned purpose, the dual independent lifting paper table loading device provided by the present invention includes a frame and a detection component installed on the frame, a first lifting paper table device and a second lifting paper table device, and the frame is provided with a first workstation and a second workstation at intervals. The first lifting paper table device is used to lift and lower the first carrier at the first workstation, and the second lifting paper table device is used to lift and lower the second carrier at the second workstation. The detection component is used to detect the height of the paper stacked on the first carrier and to detect the height of the paper stacked on the second carrier. The information fed back by the detection component drives the first lifting paper table device and the second lifting paper table device to adjust the paper height by lifting and lowering and make the highest point of the paper stacked on the first carrier flush with the highest point of the paper stacked on the second carrier.

[0007] Preferably, the first paper lifting platform device has a liftable lifting platform, and the lifting of the lifting platform drives the stacked papers on the first carrier to rise. The second paper lifting platform device has a space avoidance frame and a carrying rod. The space avoidance frame is arranged around the outer edge of the lifting platform and the space avoidance frame and the lifting platform are staggered. The carrying rod can be mounted on the space avoidance frame and carried on the bottom of the second carrier. The space avoidance frame is higher than the lifting platform and rises relative to the lifting platform to lift the stacked papers on the second carrier to rise, so as to adjust the relative height of the first carrier and the second carrier.

[0008] Specifically, the first paper lifting platform device also includes a first lifting drive device, the first lifting drive device is installed on the frame, the lifting platform is installed on the output end of the first lifting drive device, and the lifting platform is lifted and lowered by the drive of the first lifting drive device.

[0009] Specifically, the second paper lifting platform device also includes a second lifting drive device, the second lifting drive device is installed on the frame, the air avoidance frame is installed on the output end of the second lifting drive device, and the air avoidance frame is lifted and lowered under the drive of the second lifting drive device.

[0010] Specifically, the supporting rod is a straight rod structure, and both ends of the straight rod structure have gripping portions for easy gripping.

[0011] Specifically, a positioning groove is formed at the bottom of the second carrier, and the carrying rod is inserted into the positioning groove.

[0012] Specifically, a plurality of the bearing rods and the positioning grooves are provided, the plurality of bearing rods are arranged at equal intervals, and the positions of the positioning grooves correspond to those of the bearing rods.

[0013] Specifically, the air avoidance frame is a rectangular frame, and the lifting platform is a rectangular platform.

[0014] Preferably, the detection component includes a first detection and suction mechanism and a second detection and suction mechanism, the first detection and suction mechanism is used to detect the height of the stacked papers on the first carrier and suction, and the second detection and suction mechanism is used to detect the height of the stacked papers on the second carrier and suction.

[0015] Compared with the prior art, the dual-independent paper lifting platform loading device of the present invention combines the detection component, the first paper lifting platform device and the second paper lifting platform device together, and a first station and a second station are spaced apart in the frame. The first station is provided with a first carrier stacked with papers, and the second station is provided with a second carrier stacked with papers, so as to load two sheets of paper correspondingly. The first paper lifting platform device is used for lifting and lowering the first carrier at the first station, and the lifting and lowering drive the lifting and lowering of the first carrier and adjust the position of the highest point of the papers stacked on the first carrier. The first paper lifting platform device is used for lifting and lowering the second carrier at the second station, and the lifting and lowering drive the lifting and lowering of the second carrier and adjust the position of the highest point of the papers stacked on the second carrier. The detection component is used to detect the height of the papers stacked on the first carrier and the height of the papers stacked on the second carrier. The information fed back by the detection component drives the first paper lifting platform device and the second paper lifting platform device to adjust the height of the papers by lifting and lowering so that the highest point of the papers stacked on the first carrier is flush with the highest point of the papers stacked on the second carrier, that is, the topmost paper at the first station is flush with the topmost paper at the second station, and the first carrier and the second carrier are adjusted separately. Only the relative position between the first carrier and the second carrier needs to be adjusted to adjust the relative height of the papers so that the topmost papers are flush, which makes it easier for subsequent devices to absorb and load materials at the same time to meet the needs of subsequent assembly line production.

[0019] See also Figures 1 to 3, shows a dual-independent lifting paper table loading device 100 of the present invention, which is used for loading and position adjustment of two parallel papers, the dual-independent lifting paper table loading device 100 of the present invention includes a frame 1, a detection component 2, a first lifting paper table device 3 and a second lifting paper table device 4, the detection component 2, the first lifting paper table device 3 and the second lifting paper table device 4 are all installed on the frame 1, and a first station 11 and a second station 12 are provided in the frame 1 at intervals. The first station 11 and the second station 12 are arranged at intervals along the left and right directions of the frame 1, the first station 11 is provided with a first carrier 5 stacked with papers, and the second station 12 is provided with a second carrier 6 stacked with papers, so as to correspondingly load the two sheets of paper, the first lifting paper table device 3 is used for lifting the first carrier 5 at the first station 11, and drives the lifting of the first carrier 5 and adjusts the position of the highest point of the papers stacked on the first carrier 5 by lifting, the first lifting paper table device 3 is used for lifting the second carrier 6 at the second station 12, and drives the lifting of the first carrier 5 and adjusts the position of the highest point of the papers stacked on the first carrier 5 by lifting. The lowering drives the second carrier 6 to rise and fall and adjust the position of the highest point of the stacked paper on the second carrier 6. Only when the highest points of the paper on the two carriers are aligned can the subsequent production needs be met. The detection component 2 is used to detect the height of the stacked paper on the first carrier 5 and the height of the stacked paper on the second carrier 6. The detection component 2 is a position detection sensor. The information fed back by the detection component 2 drives the first lifting paper platform device 3 and the second lifting paper platform device 4 to adjust the paper height by lifting and lowering and make the highest point of the stacked paper on the first carrier 5 and the highest point of the stacked paper on the second carrier 6 aligned, that is, the topmost paper at the first station 11 and the topmost paper at the second station 12 are aligned with each other. The first carrier 5 and the second carrier 6 form separate adjustments. It is only necessary to adjust the relative position between the first carrier 5 and the second carrier 6 to adjust the relative height of the paper so that the topmost paper is aligned. This facilitates the subsequent devices to absorb and load materials at the same time to meet the needs of subsequent assembly line production. More specifically, as follows:

[0020] See also Figures 1 to 3The first paper lifting platform device 3 includes a first lifting drive device 32 and a lifting platform 31 that can be lifted and lowered. The first lifting drive device 32 is installed on the frame 1, and the lifting platform 31 is installed at the output end of the first lifting drive device 32. The lifting platform 31 is lifted and lowered by the first lifting drive device 32. The lifting and lowering of the lifting platform 31 drives the stacked papers on the first carrier 5 to rise. The second paper lifting platform device 4 includes a second lifting drive device 43, a clearance frame 41 and a carrying rod 42. The second lifting drive device 43 is installed on the frame 1, and the clearance frame 41 is installed at the output end of the second lifting drive device 43. The clearance frame 41 is lifted and lowered by the second lifting drive device 43. The air avoidance frame 41 is arranged around the outer edge of the lifting platform 31 and the air avoidance frame 41 is staggered with the lifting platform 31, that is, there will be no interference between the lifting of the air avoidance frame 41 and the lifting of the lifting platform 31. The load-bearing rod 42 can be carried on the air avoidance frame 41 and carried on the bottom of the second carrier 6. It can be understood that the load-bearing rod 42 is inserted between the air avoidance frame 41 and the second carrier 6 during operation by the operator. There are generally two load-bearing rods 42, which are symmetrically arranged on both sides of the second carrier 6. The rise of the air avoidance frame 41 will drive the load-bearing rod 42 to rise, and the rise of the load-bearing rod 42 will The second carrier 6 is lifted up, and at this time the air avoidance frame 41 is separated from the lifting platform 31. The air avoidance frame 41 is higher than the lifting platform 31 and rises relative to the lifting platform 31 to lift the stacked papers on the second carrier 6 to adjust the relative height of the first carrier 5 and the second carrier 6. When resetting, the air avoidance frame 41 descends and loses support for the second carrier 6. The second carrier 6 falls onto the plate 7 of the lifting platform 31. The plate 7 is carried on the lifting platform 31. The plate 7 has the same shape as the first carrier 5. The carrying rod 42 loses its force, and the operator can remove the carrying rod 42 by pulling it out.

[0021] See also Figures 1 to 3 The load-bearing rod 42 is a straight rod structure with grips 421 at both ends for easy gripping, which makes it easier for the operator to insert the load-bearing rod 42. A positioning groove 61 is provided at the bottom of the second carrier 6 for the load-bearing rod 42 to be inserted. The positioning grooves 61 are arranged at intervals along the length direction of the second carrier 6, that is, in the left and right directions of the frame 1. The load-bearing rod 42 is inserted into the positioning grooves 61. Preferably, a plurality of load-bearing rods 42 and positioning grooves 61 are provided, and the plurality of load-bearing rods 42 are arranged at equal intervals. The positions of the positioning grooves 61 and the load-bearing rods 42 correspond to each other, thereby improving the stability of the support.

[0022] See also Figures 1 to 3The air-avoidance frame 41 is a rectangular frame, and the lifting platform 31 is a rectangular platform. The detection assembly includes a first detection and suction mechanism 21 and a second detection and suction mechanism 22. The first detection and suction mechanism 21 is used to detect the height of the stacked paper on the first carrier 5 and then suction it, while the second detection and suction mechanism 22 is used to detect the height of the stacked paper on the second carrier 6 and then suction it. Preferably, both the first detection and suction mechanism 21 and the second detection and suction mechanism 22 are suction heads equipped with detection devices.

[0023] The working process of the dual independent lifting paper table loading device 100 of the present invention specifically includes the following steps:

[0024] In the initial state, the air avoidance frame 41 is lower than the lifting platform 31, and the air avoidance frame 41 will not affect the entry of the first carrier 5 and the second carrier 6. The first carrier 5 is transported to the first workstation 11, and the second carrier 6 is transported to the second workstation 12. The lifting platform 31 rises under the drive of the first lifting drive device 32 and simultaneously drives the bottom plates of the first carrier 5 and the second carrier 6 to rise, that is, drives the second carrier 6 and the first carrier 5 to rise. The first detection and suction mechanism 21 detects the height of the stacked papers on the first carrier 5, that is, the highest point position of the papers. The second detection and suction mechanism 22 is used to detect the height of the stacked papers on the second carrier 6, that is, the highest point position of the papers. The operator inserts the carrying rod 42 between the air avoidance frame 41 and the second carrier 6. There are generally two carrying rods 42, which are symmetrically arranged at the second position. On both sides of the carrier 6, the rise of the air-avoidance frame 41 will drive the supporting rods 42 to rise, and the rise of the supporting rods 42 will support the second carrier 6 to rise, and the papers on the second carrier 6 will also rise. At this time, the air-avoidance frame 41 is separated from the plate 7 of the lifting platform 31. The air-avoidance frame 41 is higher than the lifting platform 31 and rises relative to the lifting platform 31 to lift the papers stacked on the second carrier 6 to adjust the relative height of the first carrier 5 and the second carrier 6. That is, the first lifting drive device 32 and the second lifting drive device 43 can adjust the relative height between the first carrier 5 and the second carrier 6 so that the topmost papers are flush. When the air-avoidance frame 41 descends and loses support for the second carrier 6, the operator can remove the supporting rods 42, and the air-avoidance frame 41 continues to descend, and both the first carrier 5 and the second carrier 6 can be unloaded. It can be understood that the number of sheets of paper on the second carrier 6 is always less than the number of sheets of paper on the first carrier 5.

[0025] By combining the detection component 2, the first paper lifting platform device 3 and the second paper lifting platform device 4, etc., a first workstation 11 and a second workstation 12 are provided at intervals in the frame 1. The first workstation 11 is provided with a first carrier 5 stacked with papers, and the second workstation 12 is provided with a second carrier 6 stacked with papers, so as to correspondingly load two sheets of paper. The first paper lifting platform device 3 is used for lifting and lowering the first carrier 5 at the first workstation 11, and driving the lifting and lowering of the first carrier 5 and adjusting the position of the highest point of the papers stacked on the first carrier 5 by lifting and lowering. The first paper lifting platform device 3 is used for lifting and lowering the second carrier 6 at the second workstation 12, and driving the lifting and lowering of the second carrier 6 and adjusting the position of the highest point of the papers stacked on the second carrier 6 by lifting and lowering. The detection component 2 is used The height of the stacked papers on the first carrier 5 and the height of the stacked papers on the second carrier 6 are detected, and the information fed back by the detection component 2 drives the first paper lifting platform device 3 and the second paper lifting platform device 4 to adjust the paper height by lifting and lowering so that the highest point of the stacked papers on the first carrier 5 is flush with the highest point of the stacked papers on the second carrier 6, that is, the topmost paper at the first station 11 and the topmost paper at the second station 12 are flush with each other, and the first carrier 5 and the second carrier 6 are adjusted separately. It is only necessary to adjust the relative position between the first carrier 5 and the second carrier 6 to adjust the relative height of the papers so that the topmost papers are flush, which is convenient for the subsequent devices to absorb and load materials at the same time to meet the needs of subsequent assembly line production.

[0026] The above disclosure is merely a preferred embodiment of the present invention and certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
