Abstract
Description
Technical Field
[0001] This utility model relates to the field of pallet conveying technology, specifically a system for conveying stacked pallets one by one. Background Technology
[0002] Pallets are horizontal platform devices used for the unitized loading, stacking, handling, and transportation of goods and products as unit loads. They are generally made of wood, metal, or fiberboard and facilitate the loading, unloading, and handling of unitized materials and small quantities of goods. To save floor space, pallets in warehouses are stacked to form pallet stacks. Due to the large size of the pallets, the pallet stacks are not always arranged neatly.
[0003] In today's warehousing and handling industry, forklifts are used for transfer. During the transfer process, the pallets need to be aligned with the forklifts and then moved away by the forklifts.
[0004] When loading goods onto pallets, a combination of manual and mechanical methods is generally used to place the pallets one by one onto the production line. This equipment occupies a relatively large area. Summary of the Invention
[0005] The purpose of this utility model is to provide a stacked pallet conveying system to address the shortcomings of existing technologies, thereby solving the problem of large footprint caused by pallet separation in existing technologies.
[0006] The technical solution adopted in this utility model is as follows.
[0007] A stacked pallet conveying system includes a conveyor roller support, a gantry frame, and a pallet longitudinal clamping device. The gantry frame includes two columns and a longitudinal beam, with the tops of the two columns connected to the longitudinal beam. The top surface of the conveyor roller support is provided with a conveyor roller group consisting of several longitudinal conveyor rollers with their top surfaces aligned horizontally. A conveyor roller drive motor is provided on the conveyor roller support, and each longitudinal conveyor roller is connected to the conveyor roller drive motor. The pallet input end of the conveyor roller support is located at the left or right end of the conveyor roller group.
[0008] The front and rear ends of the conveyor roller bracket are connected to a column, and each column has a chute on the side near the other column. The top and bottom of each chute are longitudinally mounted with a first transmission sprocket. The first transmission sprockets at the top of the two chutes are connected to the drive longitudinal rotation shaft. A drive longitudinal rotation shaft motor is fixed on the side of one column away from the other column and is connected to the drive longitudinal rotation shaft. The two first transmission sprockets on each chute are connected by a first transmission chain.
[0009] A lifting frame is connected between the two slides, and the lifting frame is connected to the two first transmission chains.
[0010] The pallet longitudinal clamping device is provided on the pallet input end side of the lifting frame near the conveyor roller support. There is a pallet clearance between the bottom end of the pallet longitudinal clamping device and the top surface of each longitudinal conveyor roller.
[0011] During operation, a forklift places a stack of pallets onto the pallet input end 10 of the conveyor roller bracket 1. The conveyor roller drive motor controls the longitudinal conveyor roller to rotate, the lifting frame descends, and the pallet stack enters the pallet longitudinal clamping device. The pallet longitudinal clamping device clamps the second pallet from the bottom of the stack, and the lifting frame rises to transport the bottom pallet of the stack out. This process is repeated.
[0012] The advantages of this utility model are: simple structure, stable operation, small footprint, and the ability to output pallets stacked on top of each other one by one.
[0013] As a preferred technical solution, the pallet longitudinal clamping device includes two linear drive devices, two vertical plates, two horizontal plates, and four pallet inserters.
[0014] Two linear drive devices are longitudinally arranged on the pallet input end side of the lifting frame near the conveyor roller support. The two linear drive devices are arranged in a mirror image along the center of the lifting frame. Each linear drive device is connected to a vertical plate at the end away from the other linear drive device. A horizontal plate is connected to the bottom end of each vertical plate. Two pallet inserts are movably connected to the side of each horizontal plate near the other horizontal plate. Each pallet insert is longitudinally provided with a rod on the side near the transverse center line of the top surface of the conveyor roller support.
[0015] Using this technical solution, when the pallet stack enters between the two horizontal plates, the two linear drive devices drive the two horizontal plates to move closer together, and each insert rod is inserted into the insertion hole that lifts the nearest pallet. This can ensure that the center of the pallet stack is located directly above the transverse center line of the conveyor roller group, and can stably and accurately position and output the pallets of a pallet stack one by one.
[0016] As a preferred technical solution, the linear drive device is a cylinder or an electric actuator.
[0017] As a preferred technical solution, each tray holder has a first upright post vertically positioned at its top.
[0018] As a preferred technical solution, the front and rear ends of the pallet input end side of the lifting frame near the conveyor roller bracket are each provided with a connecting plate, and a longitudinal guide shaft is connected between the two connecting plates. The top of each vertical plate is provided with a longitudinal through hole, and a sleeve is connected to the longitudinal through hole. The longitudinal guide shaft passes through the two sleeves.
[0019] Using this technical solution, the two horizontal plates operate relatively stably.
[0020] As a preferred technical solution, the two columns are connected at their bottom ends by a longitudinal rod, and a tray clearance is provided between the bottom end of the longitudinal rod and the top surface of each longitudinal conveyor roller.
[0021] As a preferred technical solution, several vertical plates are used to connect the longitudinal rods and the longitudinal beams. Attached Figure Description

[0041] The present invention will now be further described in conjunction with the accompanying drawings and embodiments.
[0042] Example 1. As... Figure 1-9 As shown, a stacked pallet conveying system includes a conveyor roller support 1, a gantry frame, and a pallet longitudinal clamping device. The gantry frame includes two columns 2 and a longitudinal beam 21, with the tops of the two columns 2 connected to the longitudinal beam 21. The top surface of the conveyor roller support 1 is provided with a conveyor roller group consisting of several longitudinal conveyor rollers 11 arranged laterally with their top surfaces flush. The conveyor roller support 1 is provided with a conveyor roller drive motor 12, and each longitudinal conveyor roller 11 is connected to the conveyor roller drive motor 12. The pallet input end 10 of the conveyor roller support 1 is located at the right end of the conveyor roller group.
[0043] The front and rear ends of the conveyor roller bracket 1 are respectively connected to a column 2. Each column 2 has a groove 22 on the side near the other column 2. The top and bottom ends of each groove 22 are longitudinally mounted with a first transmission sprocket 23. The first transmission sprocket 23 at the top of the two grooves 22 is connected to the drive longitudinal rotation shaft 24. The side of one column 2 away from the other column 2 is fixed with a drive longitudinal rotation shaft motor 25, which is connected to the drive longitudinal rotation shaft 24. The two first transmission sprockets 23 on each groove 22 are connected by a first transmission chain 26.
[0044] A lifting frame 3 is connected between the two slides 22, and the lifting frame 3 is connected to the two first transmission chains 26.
[0045] The pallet longitudinal clamping device is provided on the pallet input end 10 side of the lifting frame 3 near the conveyor roller bracket 1. There is a pallet clearance between the bottom end of the pallet longitudinal clamping device and the top surface of each longitudinal conveyor roller 11.
[0046] During operation, a pallet stack is placed onto the pallet input end 1010 of the conveyor roller bracket 1 using a forklift. The conveyor roller drive motor 12 controls the longitudinal conveyor roller 11 to rotate, the lifting frame 3 descends, and the pallet stack enters the pallet longitudinal clamping device. The pallet longitudinal clamping device clamps the second pallet from the bottom of the pallet stack, and the lifting frame 3 rises to transport the bottom pallet of the pallet stack out. This process is repeated.
[0047] The longitudinal clamping device for pallets includes two linear drive units 4, two vertical plates 41, two horizontal plates 42, and four pallet inserters.
[0048] Two linear drive devices 4 are longitudinally arranged on the pallet input end 10 side of the lifting frame 3 near the conveyor roller support 1. The two linear drive devices 4 are arranged in a mirror image along the center of the lifting frame 3. A vertical plate 41 is connected to the end of each linear drive device 4 away from the other linear drive device. A horizontal plate 42 is connected to the bottom end of each vertical plate 41. Two pallet inserts 43 are movably connected to the side of each horizontal plate 42 near the other horizontal plate 42. A rod 44 is longitudinally arranged on the side of each pallet insert near the transverse center line of the top surface of the conveyor roller support 1.
[0049] Using this technical solution, when the pallet stack enters between the two horizontal plates 42, the two linear drive devices 4 drive the two horizontal plates 42 to move closer together, and each insert rod 44 inserts into the insertion hole 51 that lifts the nearest pallet. This can ensure that the center of the pallet stack is located directly above the transverse center line of the conveyor roller group, and can stably and accurately position and output the pallets of a pallet stack one by one.
[0050] The linear drive device 4 is a cylinder.
[0051] Each tray holder has a first upright post 45 at its top.
[0052] The lifting frame 3 has connecting plates 46 at both the front and rear ends of the pallet input end 10 near the conveyor roller support 1. A longitudinal guide shaft 47 is connected between the two connecting plates 46. Each vertical plate 41 has a longitudinal through hole at its top, and a sleeve 48 is connected to the longitudinal through hole. The longitudinal guide shaft 47 passes through the two sleeves 48. With this technical solution, the two horizontal plates 42 operate relatively stably.
[0053] The two columns 2 are connected at their bottom ends by a longitudinal rod 27. A tray clearance is provided between the bottom end of the longitudinal rod 27 and the top surface of each longitudinal conveyor roller 11.
[0054] Several vertical plates 28 connect the longitudinal bar 27 and the longitudinal beam 21.
[0055] The drive wheel 17 of the conveyor roller drive motor is connected to the second drive sprocket 14 located at the rear end of a longitudinal conveyor roller 11 via the second drive chain 13.
[0056] Each longitudinal conveyor roller 11 has a third drive sprocket 15 at its rear end, and each third drive sprocket 15 is connected by a third drive chain 16.
[0057] Its beneficial effects are: this embodiment has a simple structure, stable operation, small footprint, and can output pallets stacked on top of each other one by one.
[0058] Example 2. (As shown) Figure 10-14 As shown, the difference between this embodiment and Embodiment 1 is that the pallet input end of the conveyor roller bracket 1 is located at the left end of the conveyor roller group. The linear drive device 4 is an electric actuator.
[0059] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
