Description

Technical Field

[0001] This invention relates to the field of film roll packaging technology, and in particular to a film roll buffering system. Background Technology

[0002] The roll material is a cylindrical plastic film roll. After production, it needs to be transported to various locations for sale. To protect the roll material during transportation, reduce wear and tear, and increase the transport volume, it requires suspension packaging. Suspension packaging can be understood as follows: the automated suspension packaging line first individually packages each roll material. The surface of the roll is covered with bubble wrap, then paper covers and foam padding are used to fasten both ends, and tape is wrapped to secure it. Next, vertical clamps and end caps are added to both ends of the roll material, and the two vertical clamps are then bundled together, thus suspending the roll material between the two clamps. After suspension packaging, the film roll needs to be moved from the bundling station to the stacking station, where several rolls are stacked together. To ensure the stability and waterproofing of the entire stack of film rolls during handling, manual assistance is required to install wooden cover plates on the film roll stacks and reinforce adjacent vertical clamps with wooden strips. Due to the high packaging efficiency of the automatic floating packaging line and the slow working efficiency of the manual assistance station, the palletizing station is occupied by film roll stacks for a long time, making it difficult to quickly transport the film roll stacks to the manual assistance station. Therefore, it is urgent to buffer the film roll stacks at the palletizing station to avoid affecting the normal operation of the automatic floating packaging line.

[0003] It is evident that existing technologies still need improvement and enhancement. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a film roll buffering system for buffering and transporting suspended packaged film roll stacks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A film roll buffering system includes a film transport trolley, at least one buffer transport line extending laterally, and multiple iron pallets disposed on the buffer transport line. Each buffer transport line includes two sub-buffer transport devices spaced apart laterally, which can be connected by the film transport trolley. Each sub-buffer transport device is assembled from multiple first transport components. The film transport trolley includes a second transport component and a linear transport structure for driving the second transport component to move back and forth. Both the first and second transport components include a base frame, multiple sets of conveying components disposed on the base frame and arranged along the transport direction, and a drive component drivenly connected to one of the conveying components. Adjacent conveying components are connected by transmission, and the conveying components are used to support and drive the iron pallets to move left and right.

[0007] As a further improvement to the above technical solution, each set of conveying components includes a first and second support roller rotatably disposed on one side of the base frame, and a third and fourth support roller rotatably disposed on the other side of the base frame. The axes of the first, second, third, and fourth support rollers all extend left and right. The first and third support rollers are coaxially arranged and connected by a first transmission shaft. The second and fourth support rollers are coaxially arranged and connected by a second transmission shaft. The first and second transmission shafts are connected by a first transmission assembly, and two adjacent conveying components are connected by a second transmission assembly.

[0008] As a further improvement to the above technical solution, the iron tray includes a horizontally arranged panel body and two L-shaped support legs symmetrically arranged on both sides of the panel body. The two ends of the first support roller, the second support roller, the third support roller and the fourth support roller are all mounted on the base frame through bearing seats. The first support roller and the second support roller are each provided with two protruding rings for positioning the L-shaped support legs.

[0009] As a further improvement to the above technical solution, the drive assembly includes a double-head reducer fixed on the base frame, a buffer drive motor driven by the double-head reducer, and a transmission assembly connected to the double-head reducer that does not require a first transmission shaft. The double-head reducer is positioned between the first support roller and the third support roller. One end of the double-head reducer is connected to the first support roller via a coupling and a third transmission shaft, and the other end of the double-head reducer is connected to the third support roller via a coupling and a third transmission shaft. The third transmission shaft connected to the first support roller is connected to a second transmission shaft located in front of it via a first transmission assembly.

[0010] As a further improvement to the above technical solution, at least one auxiliary roller is provided between the first and second rollers of each group of conveying components, and at least one auxiliary roller is provided between the third and fourth rollers of each group of conveying components.

[0011] As a further improvement to the above technical solution, the base frame is provided with a cover plate for sealing the drive assembly, the first transmission assembly, and the second transmission assembly.

[0012] As a further improvement to the above technical solution, the buffer transport lines are provided with N lines and are arranged at intervals in the front-back direction, where N is an integer greater than or equal to 3.

[0013] As a further improvement to the above technical solution, the linear transport structure includes a frame, wheels that drive the frame to move, and a driving mechanism for controlling the rotation of the wheels.

[0014] As a further improvement to the above technical solution, the vehicle frame is provided with four traveling wheels, which are opposite each other in pairs and connected by a connecting shaft; the traveling drive mechanism includes a traveling drive motor, a first transmission gear mounted on the main shaft of the traveling drive motor and a second transmission gear sleeved on the connecting shaft, and the first transmission gear and the second transmission gear mesh and transmit power.

[0015] As a further improvement to the above technical solution, at least two guide rails extending in the front-to-back direction are provided on the ground, and the traveling wheels are connected to the corresponding guide rails.

[0016] Beneficial effects:

[0017] Compared to existing technologies, by setting up a film roll buffer system between the automated suspension packaging line and the manual cooperation area, the film transport trolley can not only connect with the buffer transport line to transport film roll stacks to the sub-buffer transport device for buffering, thus preventing film roll stacks from occupying the palletizing station for a long time and affecting the automatic suspension packaging line's palletizing operation, but also can orderly allocate film roll stacks to the manual cooperation station under the control of the control system. In addition, using iron pallets to support the film roll stacks provides good load-bearing capacity and continuous stability during transportation, without shaking or vibration, creating a good working condition for flexible start and stop.

[0026] This invention provides a membrane roll buffer system. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the scope of protection of the invention.

[0027] Please see Figures 1-8 This invention provides a film roll buffering system, including a film transport trolley 3, at least one buffer transport line 4 extending laterally, and multiple iron trays 2 disposed on the buffer transport line 4. Each buffer transport line 4 includes two sub-buffer transport devices 41 spaced apart laterally, which can be connected by the film transport trolley 3. Each sub-buffer transport device 41 is assembled from multiple first transport components 42. The film transport trolley 3 includes a second transport component 31 and a linear transport structure 32 for driving the second transport component 42 to move back and forth. The first transport component 42 and the second transport component 31 have the same structure. Both the first transport component 42 and the second transport component 31 include a base frame 11, multiple sets of conveying components 12 disposed on the base frame and arranged along the transport direction, and a drive component 13 drivenly connected to one of the conveying components. Adjacent two conveying components 12 are connected by transmission, and the conveying component 12 is used to support and drive the iron trays to move left and right.

[0028] In practical applications, a palletizing station 61 is set on the buffer transport line 4 closest to the automatic floating packaging line. For ease of understanding, the buffer transport line 4 closest to the automatic floating packaging line is designated as the first buffer transport line; that is, the palletizing station 61 is located between the two sub-buffer transport devices 41 of the first buffer transport line, in an area for the film transport trolley 3 to connect. When it is necessary to palletize the film rolls after floating packaging, the film transport trolley 3 moves between the two sub-buffer transport devices 41 of the first buffer transport line 4, and the second transport component 31 connects with the first transport components 42 on its left and right sides. At this time, the palletizing station 61 is located above the second transport component 31. The first transport component 42 and the second transport component 31 cooperate with each other to adjust the iron on the first buffer transport line 4. The pallet position is determined, and an empty iron pallet is transported to the top of the second transport component 31. Then, the palletizing robot 5 moves the suspended packaged film roll from the bundling station to the palletizing station 61. The film roll is stacked on the iron pallet 2. The film roll stack 8 can be transferred in the following ways according to the actual production situation: 1. The film roll stack 8 is transported to the sub-buffer transport device 41 on the first buffer transport line for buffering; 2. When the film roll buffering system adds a buffer transport line 4 in addition to the first buffer transport line, the film transport trolley 3 transports the film roll stack 8 to other buffer transport lines 4 for buffering; 3. The film transport trolley 3 moves the film roll stack 8 to the side of the manual cooperation station 62, and the second transport component 31 transports the iron pallet and the film roll stack 8 to the manual cooperation station 62.

[0029] Compared with existing technologies, by setting up a film roll buffer system between the automated floating packaging line and the manual cooperation area, the film transport trolley 3 can not only connect with the buffer transport line 4 to transport the film roll stacks 8 to the sub-buffer transport device 41 for buffering, thus preventing the film roll stacks 8 from occupying the palletizing station 61 for a long time and affecting the automatic floating packaging line's palletizing operation, but also can orderly allocate the film roll stacks 8 to the manual cooperation station 62 under the control of the control system. In addition, the use of iron pallets to support the film roll stacks 8 provides good load-bearing capacity and ensures continuous stability during transportation without shaking or vibration, creating a good working condition for flexible start and stop.

[0030] Specifically, each set of conveying components 12 includes a first roller 121 and a second roller 122 rotatably mounted on one side of the base frame 11, and a third roller 123 and a fourth roller 124 rotatably mounted on the other side of the base frame 11. The axes of the first roller 121, the second roller 122, the third roller 123, and the fourth roller 124 all extend left and right. The first roller 121 and the third roller 123 are coaxially arranged and connected by a first drive shaft 125. The second roller 122 and the fourth roller 124 are coaxially arranged and connected by a second drive shaft 126. The first drive shaft 125 and the second drive shaft 126 are connected by a first drive assembly 15, and two adjacent conveying components 12 are connected by a second drive assembly 16. The first drive assembly 15 and the second drive assembly 16 can specifically adopt a chain drive, synchronous belt drive, or other transmission methods.

[0031] Specifically, the iron pallet 2 includes a horizontally arranged panel body 21 and two L-shaped supports 22 symmetrically arranged on both sides of the panel body 21. The panel body 21 and the L-shaped supports 22 are integrally formed, and the iron pallet 2 has good load-bearing capacity. In one material handling method, a wooden pallet 70 is placed on the upper surface of the iron pallet 2, and then the film roll stack 8 is placed on the wooden pallet 70. This facilitates the removal of the wooden pallet and film roll stack 8 from the iron pallet 2 by a forklift after the film roll stack is finally packaged.

[0032] The first roller 121, the second roller 122, the third roller 123, and the fourth roller 124 are all mounted on the base frame 11 at both ends via bearing seats. The first roller 121 and the second roller 122 are rollers with two protruding rings 1211, while the third roller 123 and the fourth roller 124 are flat rollers. One of the L-shaped support legs 22 of the iron pallet is engaged between the two protruding rings 1211, preventing the iron pallet 2 from moving left or right. This positions the L-shaped support leg 22 of the iron pallet 2, improving the stability of the iron pallet 2's movement. Of course, the third roller 123 and the fourth roller 124 can also be rollers with two protruding rings 1211.

[0033] Specifically, the drive assembly 13 includes a double-head reducer 131 fixed on the base frame 11, a transport drive motor 132 connected to the double-head reducer 131, and a transmission assembly 12 connected to the double-head reducer 131 that does not require a first transmission shaft 125. The double-head reducer 131 is located between the first support roller 121 and the third support roller 123. One end of the double-head reducer 131 is connected to the first support roller 121 via a coupling 133 and a third transmission shaft 134, and the other end of the double-head reducer 131 is connected to the third support roller 123 via a coupling 133 and a third transmission shaft 134. The third transmission shaft 134 connected to the first support roller 121 is connected to a second transmission shaft 126 located in front of it via a first transmission assembly 15. That is, the transport drive motor 132 drives the first support roller 121 and the third support roller 123 to rotate synchronously through the double-head reducer 131, and under the drive of the first transmission assembly 15 and the second transmission shaft 126, it drives the second support roller 122 and the fourth support roller 124 to rotate synchronously, thereby driving all the conveying assemblies 12 to rotate synchronously. The transport drive motor 132 adjusts the forward and reverse power output, thereby causing the conveying assemblies 12 to move in the forward and reverse directions, thereby driving the iron pallet 2 to move forward or backward.

[0034] In order to better support the iron pallet 2 and make the iron pallet 2 move more smoothly, at least one auxiliary roller 18 is provided between the first roller 121 and the second roller 122 of each group of conveying components 12, and at least one auxiliary roller 18 is provided between the third roller 123 and the fourth roller 124 of each group of conveying components 12.

[0035] Preferably, the base frame 11 is provided with a cover plate 111 for covering the drive assembly 13, the first transmission assembly 15, and the second transmission assembly 16. By providing the cover plate 111, dust and foreign objects can be reduced from contaminating the first transmission assembly 15 and the second transmission assembly 16, thus reducing abnormal noise and jamming, and ensuring the smooth movement of the first transmission assembly 15 and the second transmission assembly 16.

[0036] In this embodiment, N buffer transport lines 4 are provided and arranged at intervals along the front-to-back direction, where N is an integer greater than or equal to 3. Providing multiple buffer transport lines can better distribute the buffering pressure of the membrane roll stack and improve the buffering flexibility of the membrane roll stack.

[0037] Specifically, the linear transport structure 32 includes a frame 321, wheels 322 that drive the frame 321 to move, and a drive mechanism. The second transport component 31 is mounted on the frame 321. The drive mechanism controls the rotation of the wheels 322 to move the transport trolley back and forth. A battery is installed on the frame 321 to provide power to the drive mechanism.

[0038] Furthermore, the frame 321 is equipped with four wheels 322, which are arranged in pairs facing each other and connected by a connecting shaft. The driving mechanism includes a driving motor, a first transmission gear 323 mounted on the main shaft of the driving motor, and a second transmission gear 324 sleeved on the connecting shaft. The first transmission gear 323 and the second transmission gear 324 mesh and transmit power. Driven by the driving motor, the first transmission gear 323 and the second transmission gear 324 mesh and transmit power, thereby driving the wheels 322 on the connecting shaft to move, enabling the transport trolley to move between the palletizing station 61 and the manual cooperation station 62.

[0039] Preferably, at least two guide rails 7 extending in the front-to-back direction are provided on the ground, and the traveling wheel 322 is connected to the corresponding guide rail 7. Under the guidance of the guide rails 7, the traveling wheel 322 is ensured to travel accurately and will not derail.
