Description

Technical Field

[0001] The utility model relates to the technical field of material chopping devices, and particularly relates to an efficient automatic pallet removing device. Background Art

[0002] In the industrial and food processing production processes, the use of pallets is very common. For example, in the production, processing, and transportation of edible fungi, it is often necessary to place the edible fungi in pallets for processing and transfer. The traditional manual pallet removing method has many problems such as consuming a large amount of manpower and time, low efficiency, and easy operation errors. Especially for relatively heavy pallets, manual operation is even impossible.

[0003] With the development of technology, the requirements for production efficiency and quality are getting higher and higher. The manual pallet removing method obviously cannot meet the needs of large-scale production and efficient operation. In this case, there are already devices in the prior art that can automatically remove pallets. For example, a loading and unloading device disclosed in a Chinese utility model patent with the publication number CN204528606U and the publication date of August 5, 2015, includes a loading mechanism and an unloading mechanism. When loading, a plurality of stacked pallets are placed on the loading support. The support component supports the second-to-last pallet to separate it from the last pallet. Subsequently, the loading push plate pushes the last pallet to the picking position, and then the loading push plate resets, and the support component resets. The existing pallet removing structure has at least the following defects: 1) It is not applicable to some pallets, such as when there is no gap between the stacked pallets, it is impossible to clamp the second-to-last pallet to separate it from the last pallet; 2) Only after the loading push plate resets, the support component can reset to make the lifted pallet fall, and the two actions cannot be carried out simultaneously, resulting in a long pallet removing cycle and low efficiency. Therefore, it is necessary to improve the prior art to overcome the defects in the prior art. Summary of the Utility Model

[0026] The following describes in detail the preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0027] Refer to Figures 1 to 5 , the present invention provides an efficient automatic pallet - removing device, including: a loading conveyor line 1, a lifting device 3 and a pushing device 4.

[0028] Among them, the loading conveyor line 1 is arranged on one side of the lifting device 3 and is used for conveying a plurality of stacked pallets 2.

[0029] As Figure 2 shown, the loading conveyor line 1 in the present invention specifically includes a loading roller conveyor line 11 and two protective baffles 12 arranged above both sides of the loading roller conveyor line 11. The space between the two protective baffles 12 is a loading channel. When the loading roller conveyor line 11 conveys a plurality of stacked pallets 2 through the loading channel, the two - side protective baffles 12 are used to protect them to prevent the pallets 2 from tipping, skewing and other conditions.

[0030] Furthermore, the lifting device 3 includes a frame 31, a lifting car 32 slidably arranged on the frame 31 in the vertical direction, and a first lifting drive device 33 connected to the lifting car 32. The bottom of the lifting car 32 is provided with a feeding conveyor line 34, and the feeding conveyor line 34 is docked with the loading conveyor line 1 to receive a plurality of pallets 2 conveyed by the loading conveyor line 1.

[0031] Furthermore, the pusher device 4 includes a push plate mechanism 41 and a second lifting drive device. The second lifting drive device is used to drive the push plate mechanism 41 to move up and down. The first lifting drive device 33 is used to drive the lifting car 32 to lift multiple pallets 2, and make one pallet 2 at the topmost position face the push plate mechanism 41. The push plate mechanism 41 is used to push one pallet 2 at the topmost position out of the lifting car 32.

[0032] During operation, multiple stacked pallets 2 can be placed on the feeding conveyor 1 by a forklift. The feeding conveyor 1 feeds multiple pallets 2 onto the feeding conveyor line 34 simultaneously. Multiple pallets 2 enter the lifting car 32 under the conveyance of the feeding conveyor line 34. After reaching the designated position, the feeding conveyor line 34 stops conveying. Then, the first lifting drive device 33 drives the lifting car 32 to lift multiple pallets 2, so that one pallet 2 at the topmost position is lifted to a position facing the push plate mechanism 41. The push plate mechanism 41 pushes one pallet 2 at the topmost position out of the lifting car 32. Then, the second lifting drive device drives the push plate mechanism 41 to move up a certain height, and the push plate mechanism 41 resets to the state before pushing. Since the push plate mechanism 41 is driven by the second lifting drive device to move up a certain height, when the push plate mechanism 41 starts to reset, the first lifting drive device 33 can drive the lifting car 32 to lift up, and the lifting height is the thickness of one pallet 2. After that, the second lifting drive device drives the push plate mechanism 41 to descend and reset, so that the push plate mechanism 41 returns to the state facing one pallet 2 at the topmost position, and the push plate mechanism 41 pushes one pallet 2 at the topmost position out of the lifting car 32. Repeat the above steps until all pallets 2 are pushed out of the lifting car 32.

[0033] The high-efficiency automatic pallet disassembling device of the present utility model conveys multiple stacked pallets 2 into the lifting car 32 through the feeding conveyor 1. The lifting car 32 is driven by the first lifting drive device 33 to rise by the thickness of one pallet 2 each time, so that one pallet 2 at the topmost position faces the push plate mechanism 41. Then, relying on the push plate mechanism 41, one pallet 2 at the topmost position is pushed out of the lifting car 32, so as to disassemble the pallets 2 one by one in an orderly manner, achieve high-efficiency automatic pallet disassembly, reduce labor input, and lower production costs. It can be applicable to pallets 2 without gaps in stacking. At the same time, in each cycle of pushing out one pallet 2, the second lifting drive device drives the push plate mechanism 41 to move up a certain height, so that when the push plate mechanism 41 resets, the first lifting drive device 33 can drive the lifting car 32 to lift up by the thickness of one pallet 2, enabling the two actions of the reset of the push plate mechanism 41 and the lifting of the lifting car 32 to be carried out simultaneously without waiting, greatly shortening the pallet disassembly cycle and improving the pallet disassembly efficiency, thus better meeting the production requirements and enhancing the core competitiveness of the entire industry.

[0034] Refer to Figure 3, the lifting car 32 in this embodiment is of a rectangular frame structure, and rollers are installed at positions close to its eight corners. The lifting car 32 is slidably installed on the frame 31 through the rollers. One side of the lifting car 32 facing the feeding conveyor line 1 is the feeding port, and the side opposite to the feeding port is the discharging port. Rotating baffle mechanisms 35 are installed on both sides of the feeding port of the lifting car 32. The rotating baffle mechanism 35 includes a rotating baffle 351 and a first cylinder 352. The rotating baffle 351 is axially arranged on the lifting car 32 in the vertical direction, and the first cylinder 352 is rotatably installed on the lifting car 32 and hinged to the rotating baffle 351.

[0035] When the feeding conveyor line 1 needs to convey the tray 2 into the lifting car 32, the first cylinders 352 on both sides drive their respective rotating baffles 351 to rotate and open; when the tray 2 is conveyed into the lifting car 32 and reaches the specified position, the first cylinders 352 on both sides drive their respective rotating baffles 351 to rotate and close (as Figure 3 shown in the state), and the two rotating baffles 351 can protect multiple stacked trays 2 to prevent the trays 2 from tipping, skewing, etc., and avoid the pushing plate mechanism 41 being unable to push the tray 2 due to inclination.

[0036] Exemplarily, the feeding conveyor line 34 is a roller conveyor line, and its conveying direction is the same as that of the feeding roller conveyor line 11.

[0037] Refer to Figure 4 , the first lifting drive device 33 includes a drive motor 331, a transmission shaft 332, and a traction chain 333. The transmission shaft 332 is rotatably installed at the top of the frame 31, and the drive motor 331 is fixed at the top of the frame 31 and connected to the transmission shaft 332 through a chain drive mechanism 334. An upper sprocket 335 is fixed on the transmission shaft 332, a lower sprocket 336 is installed at the bottom of the frame 31, and both ends of the traction chain 333 are respectively wound around the upper sprocket 335 and the lower sprocket 336 and then fixedly connected to the lifting car 32.

[0038] In order to improve the stability and reliability of the lifting movement of the lifting car 32, two transmission shafts 332 arranged side by side are provided in the present utility model. The two transmission shafts 332 are respectively connected to the drive motor 331 through two chain drive mechanisms 334, that is, the drive motor 331 can simultaneously drive the two transmission shafts 332 to rotate through the two chain drive mechanisms 334. Upper sprockets 335 are fixed at both ends of each transmission shaft 332. The number of the traction chains 333 and the lower sprockets 336 is the same, both being four. After the four traction chains 333 are wound around the corresponding upper sprockets 335 and lower sprockets 336, they are all fixedly connected to the lifting car 32.

[0039] Preferably, the drive motor 331 is a servo motor to ensure the accuracy of the up and down movement of the lifting car 32.

[0040] See also Figure 5 The push plate mechanism 41 includes a mounting bracket 411, a push plate 412 and a push cylinder 413. Two second guide pillars 47 are fixed to the mounting bracket 411 in the horizontal direction, and the push plate 412 is slidably fitted on the two second guide pillars 47. The push cylinder 413 is fixed to the mounting bracket 411 in the horizontal direction and connected to the push plate 412. The push cylinder 413 drives the push plate 412 to move laterally along the conveying direction of the loading conveyor line 1 to push a tray 2 at the top out of the lifting car 32.

[0041] See also Figure 1 and Figure 5 A fixed top plate 311 is provided on the top of the frame 31, and a mounting bracket 411 is located below the fixed top plate 311 and is slidably connected to the fixed top plate 311 through four first guide pillars 43. The second lifting drive device includes a lifting cylinder 42, which is fixed on the fixed top plate 311 in the vertical direction and connected to the mounting bracket 411 through a transmission shaft 46. The lifting cylinder 42 drives the push plate mechanism 41 to perform lifting motion through the transmission shaft 46.

[0042] In addition, two stopper assemblies are installed on the mounting bracket 411. The two stopper assemblies are located at both sides of the discharge port of the lifting car 32. The stopper assemblies include a second cylinder 44 and a stopper rod 45 installed on the second cylinder 44. The stopper rod 45 is driven by the second cylinder 44 to stop the tray 2 below the top tray 2. When the push cylinder 413 drives the push plate 412 to push the top tray 2, the second cylinder 44 drives the stopper rod 45 to extend toward the discharge port to stop the second tray 2, so as to prevent the top tray 2 from bringing out the tray 2 below when it is pushed out, thereby ensuring the accuracy of the tray removal process.

[0043] It is worth mentioning that the efficient automatic pallet dismantling device of the utility model further includes a material unloading conveyor line 5 , one end of which is connected to the material discharge port of the lifting car 32 for receiving the pallet 2 pushed out by the push plate 412 .

[0044] Exemplarily, the unloading conveying line 5 may be a belt conveyor.

[0045] It can be seen that in an efficient automatic pallet - removing device of the utility model, a feeding conveyor 1 is used to convey multiple stacked pallets 2 into a lifting car 32. The lifting car 32 is driven by a first lifting drive device 33 to rise by the thickness of one pallet 2 each time, so that the top - most pallet 2 faces the push - plate mechanism 41. Then, relying on the push - plate mechanism 41, the top - most pallet 2 is pushed out of the lifting car 32. In this way, the pallets 2 are disassembled one by one in an orderly manner to achieve efficient automatic pallet - removing, reduce labor input, and lower production costs. At the same time, in each cycle of pushing out a pallet 2, the push - plate mechanism 41 is driven by a second lifting drive device to move up a certain height. When the push - plate mechanism 41 resets, the first lifting drive device 33 can drive the lifting car 32 to rise by the thickness of one pallet 2, so that the two actions of the reset of the push - plate mechanism 41 and the lifting of the lifting car 32 can be carried out simultaneously without waiting, greatly shortening the pallet - removing cycle and improving the pallet - removing efficiency, thus better meeting the production requirements and enhancing the core competitiveness of the entire industry.
