Description

Technical Field

[0001] The present invention relates to the technical field of pallet loading equipment, and particularly to a mother-child pallet splitting device. Background Art

[0002] A pallet, also known as a skid or a splint, refers to a horizontal platform device used for containerizing, stacking, handling, and transporting goods and products placed as unit loads. As a container-like containerization equipment, pallets are now widely used in production, transportation, warehousing, and circulation fields, and are considered to be one of the two key innovations in the logistics industry in the 20th century. As an important loading, storage, and transportation equipment in the logistics operation process, pallets, when used in conjunction with forklifts, play a huge role in modern logistics. The benefits it brings to modern logistics are mainly reflected in: it can achieve the unitization, standardization, and normalization of item packaging, protect items, and facilitate logistics and commercial flows. Pallets in logistics, classified by material, use, tabletop, forklift insertion method, and structure, have various types.

[0003] Existing mother-child pallet splitting devices include support devices located on both sides of a conveying frame. In the middle part of the conveying frame, a hydraulic lifting mechanism is also provided. The hydraulic lifting mechanism can lift the mother-child pallet together with the goods on it to a specified height, and then the support devices support the sub-pallet and the goods. Then the hydraulic lifting mechanism lowers the mother pallet, and then conveys the mother pallet away through a conveyor belt. Then the hydraulic lifting mechanism supports the sub-pallet and the goods again. After the support is completed, the support devices no longer support the sub-pallet, and then the sub-pallet is moved onto the conveyor belt for conveyance.

[0004] For the above technical conditions, there are still defects: after the mother-child pallets are separated, the center position of the upper sub-pallet cannot be guaranteed to be aligned with the center position of the conveyor belt, thus reducing the effect of subsequently placing the sub-pallet on the conveyor belt for conveyance.

[0005] Based on this, the present invention designs a mother-child pallet splitting device to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a mother-child pallet splitting device to solve the above technical problems.

[0007] To achieve the above purpose, the present invention provides the following technical solution: A mother-child pallet splitting device includes a conveying frame, a hydraulic lifting mechanism, and two groups of frames. The top of the hydraulic lifting mechanism is provided with a lifting platform, and the top of the lifting platform is fixedly connected with a plurality of support seats. A positioning mechanism is also provided on the conveying frame. The top of the frame is fixedly connected with a top plate, and a first cylinder is fixedly connected to the top plate. A support plate is connected to the telescopic end of the first cylinder, and an adjustment device is provided on each of the two support plates;

[0008] The adjusting device includes a second cylinder fixedly connected to the support plate. An installation seat is connected to the telescopic end of the second cylinder, and an adjusting plate is fixedly connected to one side of the installation seat.

[0009] By adopting the above technical solution, the movement of the adjusting plate is controlled by the second cylinders on both sides of the frame, so that the central position of the sub-tray can be adjusted to be flush with the central position of the lower conveyor belt, thereby improving the conveying effect of the sub-tray.

[0010] Preferably, the adjusting device further includes two groups of stabilizing seats fixedly connected to the support plate. Stabilizing columns are slidably connected inside the two groups of stabilizing seats. One end of each of the two groups of stabilizing seats is fixedly connected to a support block, and one side of each of the two groups of support blocks is fixedly connected to the inner side of the adjusting plate.

[0011] By adopting the above technical solution, the adjusting plate moves more stably, thereby improving the subsequent adjustment effect.

[0012] Preferably, an installation block is further fixedly connected to the bottom of the lifting platform and between the two support seats. A cable is fixedly connected to one side of the installation block. A bracket is fixedly connected to one side of the frame close to the conveying frame. A square tube is fixedly connected to the top of the bracket. A limiting block is sleeved on the outside of the square tube. A support rod is rotatably connected to one side of the limiting block, and one end of the support rod is rotatably connected to the bottom of the support plate.

[0013] By adopting the above technical solution, the support rod can support the side of the support plate away from the frame, thereby improving the load-bearing capacity of the support plate and further extending its service life.

[0014] Preferably, one side of the inner wall of the square tube is fixedly connected with a telescopic sleeve. One end of the telescopic sleeve is fixedly connected with a contraction block. The contraction block includes a vertical part and an inclined part. One side of the contraction block is slidably connected with a connecting rod. One end of the connecting rod is connected with a limiting block. One side of the limiting block is fixedly connected with an abutting block. The abutting block can abut against the bottom of the limiting block after extending out of the square tube. A first spring is fixedly connected between the contraction block and the limiting block. The first spring is located outside the connecting rod. One side of the limiting block is also fixedly connected with a control column. Inside the square tube and above the abutting block, there is a fixed seat fixedly connected. Inside the fixed seat, there is a reset column slidably connected. One end of the reset column is fixedly connected with a reset sleeve. The control column is located inside the reset sleeve. The reset sleeve includes a straight edge and an arc edge. A second spring is also fixedly connected between the fixed seat and the reset sleeve. The second spring is arranged outside the reset column. At the bottom of the reset sleeve, there is also a sliding seat fixedly connected. The cable passes through the sliding seat and extends above the sliding seat. One end of the cable above the sliding seat is fixedly connected with a third spring. The top end of the third spring is fixedly connected to the top of the inner wall of the square tube. On the outer wall of the cable, there is a driving block fixedly connected. The diameter of the driving block is larger than the diameter of the through hole on the sliding seat for the cable to pass through. When the third spring is in the natural state, the distance between the driving block and the sliding seat is equal to the distance that the hydraulic lifting mechanism rises for the first time.

[0015] By adopting the above technical solution, when the limiting block moves upward and contacts the inclined part, the contraction block contracts inward. At the same time, the limiting block abuts against one side of the abutting block. At this time, the first spring is compressed, and part of the connecting rod contracts into the contraction block. When the bottom of the limiting block moves to the vertical part, the vertical part will abut tightly inside the limiting block. At this time, the abutting block breaks away from the restraint of the limiting block, and the abutting block pops out from the side of the square tube under the action of the first spring. Furthermore, the abutting block can support the limiting block in the vertical direction.

[0016] Preferably, a reversing wheel is also rotatably connected to the bottom of the frame. Part of the cable contacts the outer ring surface of the reversing wheel.

[0017] By adopting the above technical solution, the reversing wheel can change the traveling direction of the cable, which is convenient for installation.

[0018] Preferably, a protective ring is fixedly connected inside the conveying frame. The cable passes through the protective ring. The protective ring is made of a highly wear-resistant material.

[0019] By adopting the above technical solution, the abrasion between the cable and the conveying frame can be reduced, thereby increasing the service life.

[0020] Preferably, the positioning mechanism includes a bottom plate, on which a middle plate and a front plate are fixedly connected. On one side of the bottom plate, a driving motor is fixedly connected. On the output shaft of the driving motor, a transmission shaft is fixedly connected. On the rotating shaft, a first positioning plate is fixedly connected. On one side of the first positioning plate, a connecting rod is rotatably connected. Between the middle plate and the front plate, a support shaft is also rotatably connected. On the outer wall of the support shaft, a second positioning plate is fixedly connected. One side of the second positioning plate is rotatably connected to one end of the connecting rod.

[0021] By adopting the above technical solution, by simultaneously controlling the flipping of the two groups of positioning plates through the driving motor, the tray during transportation can be blocked, so that the mother and son trays can stop at the designated positions.

[0022] Preferably, on the top of the bottom plate and between the middle plate and the front plate, two protective seats for abutting against the two groups of positioning plates are fixedly connected. Grooves are formed on the tops of the two protective seats, and first contact sensors are arranged inside the grooves.

[0023] By adopting the above technical solution, the two protective seats can protect the two groups of positioning plates, reducing the damage caused by the hard contact between the positioning plates and the bottom plate. At the same time, when the first contact sensor contacts the positioning plate, it means that the positioning plate has been completely flipped in place, that is, the subsequent transportation work can be carried out.

[0024] Preferably, second contact sensors are arranged on one side of the first positioning plate and the second positioning plate.

[0025] By adopting the above technical solution, after the tray contacts the second sensor, the conveyor belt can be controlled to stop immediately, thereby reducing the continuous force on the positioning plate.

[0026] Preferably, sliders are fixedly connected to the bottoms of both sides of the support plate, and slide rails are also fixedly connected to both sides of the top plate. The sliders are slidably connected to the slide rails.

[0027] By adopting the above technical solution, the support plate moves more stably, and at the same time, the supporting ability of the support plate is further increased.

[0028] In summary, the present application has the following beneficial technical effects:

[0029] 1. Through the two sets of adjustment devices arranged symmetrically, on which adjustment plates driven by second air cylinders are provided, by controlling the positions of the adjustment plates through the telescopic ends of the second air cylinders, the position of the sub-tray can be adjusted so that the sub-tray can also be located in the center position for subsequent transportation;

[0030] Furthermore, by providing the stabilizing base and the stabilizing column, the adjusting plate moves more stably during movement, thereby enhancing the effect of adjusting the position of the sub-tray. Then, the support block can disperse the force on the stabilizing column and extend its service life.

[0031] 2. By providing the support rod and the limiting block, the support rod is rotatably connected to the side of the support plate away from the frame. When a large pressure is applied to the side of the support plate away from the frame, the support rod can bear part of the pressure, so that the support plate will not deform even when subjected to a large pressure, effectively enhancing the load-bearing capacity of the support plate.

[0032] Furthermore, through the structures such as the cable, the shrinking block, the pressing block, the control column and the reset sleeve, when the support plate extends, the support rod drives the limiting block to move upward outside the square tube. When the limiting block contacts the inclined part, the telescopic block shrinks inward. At the same time, the limiting block presses against one side of the pressing block. At this time, the first spring is compressed, and part of the connecting rod shrinks into the shrinking block. When the bottom of the limiting block moves to the vertical part, the vertical part will press tightly inside the limiting block. At this time, the pressing block breaks away from the restraint of the limiting block, and the pressing block pops out from the side of the square tube under the action of the first spring. Thus, the pressing block can support the limiting block in the vertical direction, thereby providing support for the support rod and the support plate.

[0033] Still further, through the cable, the driving block and the sliding seat, etc., during a mother-child tray splitting operation, the hydraulic lifting mechanism will control the lifting platform to rise and fall twice. When the lifting platform rises for the first time, the mother-child tray is lifted to a specified height, and then the support plate is inserted between the mother-child trays to support the sub-tray. At this time, the cable pulls the driving block to move to a position in contact with the top of the sliding seat. When the hydraulic lifting mechanism lowers the mother tray, under the action of the third spring, the cable and the driving block are reset. After the mother tray is conveyed away, the lifting platform rises for the second time. Due to the loss of the mother tray, the height of the second rise needs to be increased by the thickness of a mother tray compared to the first rise. After the lifting platform rises to the specified height for the second time, the cable pulls the driving block to control the sliding seat to move downward, thereby causing the reset sleeve to move downward. The control column is squeezed toward the straight edge through the arc edge, so that the pressing block shrinks inward, so that the pressing block no longer blocks the limiting block. Then, when the support plate contracts, the support rod drives the limiting block to move downward, so that the support plate is not blocked during contraction. Then, the reset sleeve is reset under the action of the second spring and can perform the next operation.

[0034] 3. By providing the positioning mechanism, which is provided with a connecting rod inside, only one driving motor is needed to simultaneously control the two positioning plates to flip, so as to ensure that the two positioning plates are synchronized and enhance the positioning effect on the tray.

[0035] Furthermore, through the two sets of protective seats provided, the positioning plate can be protected during storage, preventing the positioning plate from directly hitting the bottom plate when retracting, increasing its service life. At the same time, a first contact sensor is also provided on the protective seat. When the positioning plate contacts the first contact sensor, it indicates that the positioning plate has been fully retracted, and then the conveyor belt can be controlled to operate, avoiding the pallet from colliding with the incompletely retracted positioning plate during transportation;

[0036] Furthermore, through the second contact sensors provided on the two sets of positioning plates, a contact signal can be sent in a timely manner when the pallet contacts the positioning plate. At this time, the conveyor belt can be controlled to immediately pause, so that the positioning plate will not continue to be under pressure from the pallet, increasing the service life of the positioning plate.

[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0049] The following is further described in conjunction with the attached Figure 1-8 This application is further described in detail.

[0050] A mother-child tray splitting device, comprising a conveying frame 1, a hydraulic lifting mechanism 2 and two groups of frames 3 respectively arranged on both sides of the conveying frame 1. The conveying frame 1 is part of the transportation line, which is powered by a motor, and then the conveyor belt can drive the articles above to move. The hydraulic lifting mechanism 2 is a hydraulic drive mechanism that can control the lifting platform 4 above to rise or fall. A lifting platform 4 is arranged at the top of the hydraulic lifting mechanism 2. A plurality of support seats 5 are fixedly connected to the top of the lifting platform 4. The support seats 5 are used to support the bottom of the tray, so that there is a space for a forklift or a support plate 11 to be inserted into the bottom of the tray. A positioning mechanism 8 is also arranged on the conveying frame 1. The positioning mechanism 8 is used to position the tray during the conveying process, so as to facilitate the subsequent tray separation work. A top plate 9 is fixedly connected to the top of the frame 3. A first cylinder 10 is fixedly connected to the top plate 9. A support plate 11 is connected to the telescopic end of the first cylinder 10. After the support plate 11 extends a certain length, it can support the sub-tray. Adjusting devices 14 are arranged on both groups of support plates 11. The two groups of adjusting devices 14 are used to adjust the position of the sub-tray on both sides to ensure that the sub-tray is located in the middle position after splitting;

[0051] The adjusting device 14 includes a second cylinder 141 fixedly connected to the support plate 11. An installation seat 142 is connected to the telescopic end of the second cylinder 141. By extending or shortening the telescopic end of the second cylinder 141, the position of the installation seat 142 can be adjusted. An adjusting plate 143 is fixedly connected to one side of the installation seat 142. The adjusting plates 143 located on both sides of the sub-tray can adjust the position of the sub-tray, so that the sub-tray can also be located in the middle position.

[0052] Furthermore, the adjusting device 14 further includes two groups of stabilizing seats 144 fixedly connected to the support plate 11. Stabilizing columns 145 are slidably connected inside the two groups of stabilizing seats 144, so that the adjusting plate 143 moves more stably, thereby improving the effect of adjusting its position. One ends of the two groups of stabilizing seats 145 are fixedly connected with support blocks 146. One sides of the two groups of support blocks 146 are fixedly connected to the inner side of the adjusting plate 143. The support blocks 146 can disperse the force, further improving the effect of tightening and adjusting.

[0053] Further, a mounting block 6 is fixedly connected to the bottom of the lifting platform 4 and between two sets of support seats 5. A cable 7 is fixedly connected to one side of the mounting block 6. A bracket 15 is fixedly connected to one side of the frame 3 close to the conveying rack 1. A square tube 16 is fixedly connected to the top of the bracket 15. A limiting block 18 is sleeved on the outside of the square tube 16. The limiting block 18 can freely slide along the axial direction of the square tube 16 without restriction. A support rod 17 is rotatably connected to one side of the limiting block 18. One end of the support rod 17 is rotatably connected to the bottom of the support plate 11, which can provide support for the end of the support plate 11 away from the frame, thereby improving its support effect and preventing the support plate 11 from deforming when subjected to a large pressure.

[0054] Further, on one side of the inner wall of the square tube 16, a telescopic sleeve 20 is fixedly connected. The telescopic sleeve 20 is composed of an outer tube and an inner tube that can freely slide inside the outer tube. At one end of the inner tube of the telescopic sleeve 20, a contraction block 21 is fixedly connected. The contraction block 21 includes a vertical portion 21a and an inclined portion 21b. The contraction block 21 is arranged in a through hole on the square tube 16 and can move into the interior of the square tube 16 or partially move outside the square tube 16. When the limit block 18 moves upward and contacts the inclined portion 21b, the contraction block 21 contracts inward. At the same time, the limit block 18 presses against one side of the pressing block 24. At this time, the first spring 25 is compressed, and a part of the connecting rod 22 contracts into the interior of the contraction block 21. When the bottom of the limit block 18 moves to the vertical portion 21a, the vertical portion 21a will press tightly inside the limit block 18. At this time, the pressing block 24 is released from the restraint of the limit block 18, and the pressing block 24 pops out from the side of the square tube 16 under the action of the first spring 25. Furthermore, the pressing block 24 can support the limit block 18 in the vertical direction. A connecting rod 22 is slidably connected to one side of the contraction block 21. At one end of the connecting rod 22, a limiting block 23 is connected. On one side of the limiting block 23, a pressing block 24 is fixedly connected. After the pressing block 24 extends out of the square tube 16, it can press tightly against the bottom of the limit block 18, thereby providing a supporting effect for the support rod 17. A first spring 25 is fixedly connected between the contraction block 21 and the limiting block 23. The first spring 25 is located outside the connecting rod 22. On one side of the limiting block 23, a control column 26 is also fixedly connected. Inside the square tube 16 and above the pressing block 24, a fixed seat 27 is fixedly connected. Inside the fixed seat 27, a reset column 28 is slidably connected. At one end of the reset column 28, a reset sleeve 29 is fixedly connected. The control column 26 is located inside the reset sleeve 29. The reset sleeve 29 includes a straight edge 29a and an arc edge 29b. A second spring 30 is also fixedly connected between the fixed seat 27 and the reset sleeve 29. The second spring 30 is arranged outside the reset column 28 and is used to reset the position of the reset sleeve 29. At the bottom of the reset sleeve 29, a sliding seat 31 is also fixedly connected. The cable 7 passes through the sliding seat 31 and extends above the sliding seat 31. One end of the cable 7 above the sliding seat 31 is fixedly connected to a third spring 32. The top end of the third spring 32 is fixedly connected to the top of the inner wall of the square tube 16. A driving block 33 is fixedly connected to the outer wall of the cable 7. The diameter of the driving block 33 is greater than the diameter of the through hole on the sliding seat 31 for the cable 7 to pass through. When the third spring 32 is in a natural state, the distance between the driving block 33 and the sliding seat 31 is equal to the distance that the hydraulic lifting mechanism 2 rises for the first time. That is, when rising for the second time, the driving block 33 can pull the sliding seat 31 to move downward.

[0055] Further, a reversing wheel 19 is also rotatably connected to the bottom of the frame 3. A part of the cable 7 contacts the outer ring surface of the reversing wheel 19, which can change the acting direction of the cable 7 and is convenient for use.

[0056] Furthermore, a protective ring 20 is fixedly connected to the inside of the conveying frame 1, and the cable 7 passes through the protective ring 20. The protective ring 20 is made of a highly wear-resistant material and has less wear when rubbing against the cable 7, thereby increasing its service life.

[0057] Furthermore, the positioning mechanism 8 includes a base plate 81, on which a middle plate 82 and a front plate 83 are fixedly connected, a driving motor 84 is fixedly connected to one side of the base plate 81, a transmission shaft 85 is fixedly connected to the output shaft of the driving motor 84, a first positioning plate 86 is fixedly connected to the rotating shaft 85, a connecting rod 87 is rotatably connected to one side of the first positioning plate 86, a support shaft 88 is also rotatably connected between the middle plate 82 and the front plate 83, a second positioning plate 89 is fixedly connected to the outer wall of the support shaft 88, one side of the second positioning plate 89 is rotatably connected to one end of the connecting rod 87, when the first positioning plate 86 rotates, the second positioning plate 89 can also rotate through the connecting rod 87, so that the first positioning plate 86 and the second positioning plate 89 rotate towards each other.

[0058] Furthermore, two groups of protection seats 810 are fixedly connected on the top of the bottom plate 81 and between the middle plate 82 and the front plate 83 , and the two groups of protection seats 810 are used to resist the two groups of positioning plates respectively.

[0059] Furthermore, grooves are provided on the tops of the two sets of protective seats 810, and contact sensors No. 1 811 are provided inside the grooves. When the positioning plate contacts the contact sensor No. 1 811, a signal indicating that the positioning plate is fully retracted is sent, and the conveyor belt can be used to control the tray to continue moving forward.

[0060] Furthermore, a second contact sensor 812 is provided on one side of the first positioning plate 86 and the second positioning plate 89. When the pallet on the conveyor belt contacts the second contact sensor 812, it sends a positioning signal to control the conveyor belt to pause conveying the pallet, thereby increasing the conveying control effect.

[0061] Furthermore, sliders 12 are fixedly connected to the bottom of both sides of the support plate 11, and slide rails 13 are also fixedly connected to both sides of the top plate 9. The sliders 12 are slidably connected to the slide rails 13, so that the movement of the sliders 12 on the slide rails 13 is more stable, while increasing the effect of the movement of the support plate 11, further improving the supporting capacity of the support plate 11.

[0062] The implementation principle of this embodiment is:

[0063] During use, the mother-and-son tray moves to one side of the positioning plate 89 under the action of the conveying rack 1. When the tray contacts the second contact sensor 812, the second contact sensor 812 emits a contact signal. At this time, the control system stops the conveying rack 1 from continuing to convey. Then, the hydraulic lifting mechanism 2 controls the lifting platform 4 to move upward, lifting the mother-and-son tray to a certain height so that the support plate 11 can support the upper son tray after it extends. Then, the first cylinder 10 is started to control the support plate 11 to move outward, so that the support plate 11 is inserted into the bottom of the son tray. Then, the lifting platform 4 is controlled to move downward. At this time, the son tray is completely supported by the two support plates 11 on both sides. By controlling the movement of the two groups of adjustment plates 143 through the second cylinders 141 on both sides respectively, the position of the son tray can be adjusted so that the center position of the son tray is aligned with the center position of the conveying rack 1 for subsequent conveying. When the support plate 11 extends, the support rod 17 drives the limit block 18 to move upward. When the limit block 18 moves upward and contacts the inclined part 21b, the telescopic block 21 contracts inward. At the same time, the limit block 18 presses against one side of the abutting block 24. At this time, the first spring 25 is compressed, and part of the connecting rod 22 contracts into the inside of the telescopic block 21. When the bottom of the limit block 18 moves to the vertical part 21a, the vertical part 21a will press tightly inside the limit block 18. At this time, the abutting block 24 is released from the restraint of the limit block 18, and the abutting block 24 pops out from the side of the square tube 16 under the action of the first spring 25. Thus, the abutting block 24 can support the limit block 18 in the vertical direction. When the lifting platform 4 moves the mother tray onto the conveying rack 1, the drive motor 84 is started. The output shaft of the drive motor 84 drives the transmission shaft 85 and the first positioning plate 86 to rotate, and then drives the second positioning plate 89 to rotate through the connecting rod 87, so that the two groups of positioning plates flip inward. When the positioning plate contacts the first contact sensor 811, a contact signal is emitted, causing the conveying rack 1 to start working and convey the mother tray. After the conveying is completed, the positioning plate is controlled to reset by the drive motor 84, and at the same time, the conveying rack 1 pauses working. Then, the hydraulic lifting mechanism 2 controls the lifting platform 4 to rise for the second time. The height difference of the second rise relative to the first rise is the thickness of a mother tray. Thus, the support seat 5 can contact the bottom of the son tray. During the second rise of the lifting platform, the cable 7 pulls the driving block 33 to control the sliding seat 31 to move downward, and then the reset sleeve 29 moves downward. The control column 26 is squeezed toward the straight edge 29a through the arc edge 29b, so that the abutting block 24 contracts inward, so that the abutting block 24 no longer blocks the limit block 18. When the support plate 11 contracts, the support rod 17 drives the limit block 18 to move downward, so that the support plate 11 is not blocked when it contracts. Then, the reset sleeve 29 resets under the action of the second spring 30 and can perform the next operation.
