Description

Technical Field

[0001] This utility model belongs to the technical field of transfer mechanism, specifically relating to a palletizing and transfer mechanism. Background Technology

[0002] In fields such as automated warehousing, food processing, and e-commerce logistics, palletizing is a key link in achieving efficient material turnover. As the core equipment connecting the "front-end conveyor line" and the "back-end palletizing station," the core function of the palletizing transfer mechanism is to transfer materials such as cartons and boxes from the upstream conveyor (such as roller conveyor) to the downstream palletizing conveyor line or palletizing robot station through the "lifting-reversing-lowering" action, replacing manual handling to improve production efficiency. A lifting transfer machine is a common palletizing and transferring mechanism. It typically uses fixed rollers to move cartons from the upstream conveyor to the center of the device and align them with the downstream conveyor. Then, a lifting mechanism, driven by cylinders or other drive mechanisms, lifts the cartons. The lifted conveyor belt directly supports the cartons and transports them to the downstream conveyor. However, because it relies solely on the friction between the pulleys and the belt for transmission, the pulleys may spin freely and the cartons may not move when the cartons are too heavy. Furthermore, the belt is a consumable part and will wear down over time, leading to decreased tension and positioning errors in the transfer distance. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a palletizing and transferring mechanism. This device transfers cartons by means of rigid transmission between gears and racks combined with the direct support and transport of the support plate. It eliminates the possibility of slippage due to insufficient friction between the pulley and belt, or between the belt and the cartons, during the conveying process, and also eliminates the need to replace easily damaged parts such as belts. Furthermore, by directly moving the cartons to the top of the conveyor rollers of the roller conveyor through the support plate, and then placing the cartons smoothly on the conveyor rollers, it also eliminates the possibility of jamming during the connection stage of the transfer process and avoids the cartons shifting during the connection process, thus improving the smoothness and accuracy of the connection.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a palletizing and transferring mechanism, comprising a transferring mechanism, wherein the feeding end of the transferring mechanism is connected to a first roller conveyor, and the discharging end of the transferring mechanism is connected to a second roller conveyor. The transferring mechanism includes a base, and a first roller mounting seat and a second roller mounting seat are mounted on the top of the base. A roller is rotatably mounted between the first roller mounting seat and the second roller mounting seat. A receiving groove is formed downward on the top of the base, and a lifting cylinder is provided inside the receiving groove. A guide rail is connected to the top of the lifting cylinder, and a slider is slidably mounted on the outer side of the guide rail. A rack is provided on the top of the guide rail, and a second motor is provided on the side of the slider. The output end of the second motor is connected to a gear, and the gear meshes with the slider. A bracket is provided on the top of the slider, and a support plate is provided on the top of the bracket. The second roller conveyor has slots on multiple conveying rollers near the transferring mechanism.

[0005] The beneficial effects of this utility model are as follows: Compared with the prior art, this device uses a lifting belt conveyor mechanism to transport the carton to a roller conveyor in another direction by utilizing the friction between the belt and the carton. This device transfers the carton by using rigid transmission between gears and racks in conjunction with the direct support of the support plate. There is no slippage due to insufficient friction between the pulley and belt, or between the belt and the carton during the conveying process, and there is no need to replace easily damaged parts such as belts. At the same time, by directly moving the carton to the top of the conveyor roller of the roller conveyor through the support plate and then placing the carton smoothly on the conveyor roller, the possibility of jamming during the connection stage of the transfer process is eliminated, and the carton is prevented from shifting during the connection process, thus improving the smoothness and accuracy of the connection.

[0006] For the conveying of cartons at the top of the transplanting mechanism: As a further improvement to the above technical solution: a sprocket is provided at one end of the rotating roller inside the second rotating roller mounting base, and a chain is connected between the sprockets of two adjacent rotating rollers. A first motor is installed on the side of the second rotating roller mounting base, and the output end of the first motor is fixed to the end of a rotating roller.

[0007] The beneficial effects of this improvement are as follows: the first motor drives the rotating roller connected to its output end to rotate, and this rotating roller drives the other rotating rollers to rotate synchronously through the transmission of sprockets and chains, so as to receive the carton from the first roller conveyor and carry it to the center position above the transfer mechanism.

[0008] To improve the structural stability of the support plate: As a further improvement to the above technical solution: an auxiliary support plate is provided at the top of one end of the guide rail, and a roller is rotatably mounted on the top of the auxiliary support plate, the roller contacting the bottom of the support plate.

[0009] The beneficial effects of this improvement are: the auxiliary support plate can provide auxiliary support to the support plate through the contact between the roller and the bottom of the support plate, thereby improving its structural stability.

[0010] To increase the friction between the support plate and the carton: As a further improvement to the above technical solution: a rubber pad is provided on the top of the support plate.

[0011] The beneficial effect of this improvement is that the rubber pad is used to increase the friction between the support plate and the carton.

[0012] To avoid structural conflicts between the support plate and the second roller conveyor: As a further improvement to the above technical solution: the support plate is provided in multiple parts, and the number of grooves on the grooved conveying roller is the same as the number of support plates. The groove depth is slightly greater than the thickness of the support plate, and the groove width is slightly greater than the width of the support plate.

[0013] The beneficial effect of this improvement is that, through the above design, the support plate can make sufficient room during movement and will not cause structural conflict with the second roller conveyor.

[0014] As a further improvement to the above technical solution: the number of grooved conveyor rollers on the second roller conveyor is the number of conveyor rollers that the support plate can cover.

[0015] To provide stable support for the lifting mechanism: As a further improvement to the above technical solution: the number of lifting cylinders is four, the number of guide rails is two, and two lifting cylinders are provided below each guide rail.

[0016] The beneficial effect of this improvement is that by using four sets of lifting cylinders to lift the two guide rails and the mechanism above them, good support stability can be provided.

[0017] To reduce costs and simplify control logic: As a further improvement to the above technical solution: only one of the two guide rails is equipped with a rack, and only the slider on that guide rail is equipped with a gear and a second motor.

[0018] The beneficial effects of this improvement are: by using a single motor to drive two sets of sliders to move synchronously along two guide rails, the cost of use is reduced and the control logic of the PLC is simplified without affecting the transmission effect.

[0019] In summary, the beneficial effects of this case are as follows: Compared to existing technologies, this device uses a lifting belt conveyor mechanism that leverages the friction between the belt and the carton to transport it to a roller conveyor in the opposite direction. This device transfers the carton via a rigid transmission between gears and racks combined with direct support from a support plate. This eliminates the risk of slippage due to insufficient friction between the pulleys and belt, or between the belt and the carton, and eliminates the need to replace easily worn parts like belts. Furthermore, by directly moving the carton above the conveyor rollers via the support plate and then placing it smoothly on the rollers, the device eliminates the possibility of jamming during the transfer process and prevents carton misalignment, thus improving the smoothness and accuracy of the connection.

[0020] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0023] like Figure 1-5As shown, a palletizing and transferring mechanism includes a transferring mechanism 2. The infeed end of the transferring mechanism 2 is connected to a first roller conveyor 1, and the discharge end of the transferring mechanism 2 is connected to a second roller conveyor 18. The transferring mechanism 2 includes a base 3. A first roller mounting seat 21 and a second roller mounting seat 22 are mounted on the top of the base 3. A roller 4 is rotatably mounted between the first roller mounting seat 21 and the second roller mounting seat 22. A receiving groove is formed downwards on the top of the base 3, and a lifting air chamber is provided inside the receiving groove. The top of the lifting cylinder 8 is connected to a guide rail 9, and a slider 10 is slidably mounted on the outer side of the guide rail 9. A rack 11 is provided on the top of the guide rail 9. A second motor 12 is provided on the side of the slider 10. The output end of the second motor 12 is connected to a gear 13. The gear 13 meshes with the slider 10. A bracket 14 is provided on the top of the slider 10. A support plate 15 is provided on the top of the bracket 14. The second roller conveyor 18 has slots 19 on multiple conveying rollers near the transfer mechanism 2.

[0024] Compared to existing technologies, this device uses a lifting belt conveyor mechanism that leverages the friction between the belt and the carton to transport it to a roller conveyor in the opposite direction. This device transfers the carton via a rigid transmission between gears and racks combined with direct support from a support plate. This eliminates the risk of slippage due to insufficient friction between the pulleys and belt, or between the belt and the carton, and eliminates the need to replace easily worn parts like belts. Furthermore, by directly moving the carton above the conveyor rollers via the support plate and then placing it smoothly on the rollers, the device eliminates the possibility of jamming during the transfer process and prevents carton misalignment, thus improving the smoothness and accuracy of the connection.

[0025] One end of the rotating roller 4 is provided with a sprocket 6 located inside the second rotating roller mounting base 22. A chain 7 is connected between the sprockets 6 of two adjacent rotating rollers 4. A first motor 5 is installed on the side of the second rotating roller mounting base 22. The output end of the first motor 5 is fixed to the end of a rotating roller 4.

[0026] The first motor 5 drives the rotating roller 4 connected to its output end to rotate. This rotating roller 4 drives the other rotating rollers 4 to rotate synchronously through the transmission of the sprocket 6 and the chain 7, so as to receive the carton from the first roller conveyor 1 and carry it to the center position above the transfer mechanism 2.

[0027] An auxiliary support plate 16 is provided at the top of one end of the guide rail 9. A roller 17 is rotatably mounted on the top of the auxiliary support plate 16, and the roller 17 contacts the bottom of the support plate 15.

[0028] The auxiliary support plate 16, through the contact between the roller 17 and the bottom of the support plate 15, can provide auxiliary support for the support plate 15 and improve its structural stability.

[0029] The top of the support plate 15 is provided with a rubber pad 20.

[0030] Rubber pad 20 is used to increase the friction between the support plate 15 and the carton.

[0031] The support plate 15 is provided in multiple ways. The number of slots 19 on the conveyor roller with slots 19 is the same as the number of support plates 15. The slot depth is slightly greater than the thickness of the support plate 15, and the slot width is slightly greater than the width of the support plate 15.

[0032] The above design allows the support plate 15 to make sufficient room during movement, preventing structural conflicts with the second roller conveyor 18.

[0033] The number of conveying rollers with slots 19 on the second roller conveyor 18 is the number of conveying rollers that the support plate 15 can cover.

[0034] There are four lifting cylinders 8 and two guide rails 9, with two lifting cylinders 8 installed below each guide rail 9.

[0035] The four sets of lifting cylinders 8 lift the two guide rails 9 and the mechanism above them, providing good support stability.

[0036] Of the two guide rails 9, only one is equipped with a rack 11, and only the slider 10 on that guide rail 9 is equipped with a gear 13 and a second motor 12.

[0037] By using a single motor to drive two sets of sliders 10 to move synchronously along two guide rails 9, the cost of use is reduced and the control logic of the PLC is simplified without affecting the transmission effect.

[0038] The working principle and usage process of this utility model are as follows: When this device is in use, the first roller conveyor 1 transports the cartons to be stacked to the top of the transfer mechanism 2. During this process, the first motor 5 drives the rotating roller 4 connected to its output end to rotate. This rotating roller 4 drives the other rotating rollers 4 to rotate synchronously through the transmission of the sprocket 6 and the chain 7, receiving the cartons from the first roller conveyor 1 and moving them to the center position above the transfer mechanism 2, completing the receiving of the cartons. Subsequently, the lifting cylinder 8 automatically moves the guide rail... 9. Lifting the support plate 15 raises the carton above the rotating roller 4, detaching it from contact with the roller 4. Then, the second motor 12 drives the gear 13 to rotate. Through the meshing between the gear 13 and the rack 11, the slider 10, along with the bracket 14 and the support plate 15, moves along the guide rail 9 towards the second rotating roller mounting base 22, moving the carton above the second roller conveyor 18. Since the outer sides of the conveyor rollers on the second roller conveyor 18 that can be covered by the support plate 15 have slots 19, ... This will not cause structural conflict or collision with the support plate 15. After the support plate 15 moves into place, the lifting cylinder 8 drives the guide rail 9 to descend along with the support plate 15, placing the carton smoothly on the conveyor rollers of the second roller conveyor 18. The carton is then conveyed to the palletizing station by the conveyor rollers of the second roller conveyor 18, completing the reverse conveying of the carton. Compared with the existing technology that uses a lifting belt conveyor mechanism to transport the carton to a roller conveyor in another direction by the friction between the belt and the carton, this device uses the rigidity between the gears and racks... The direct support and transport of cartons by the transmission and support plate eliminates the risk of slippage due to insufficient friction between the pulleys and belts, or between the belts and cartons, during the conveying process. It also eliminates the need to replace easily worn parts such as belts. Furthermore, by directly moving the cartons above the conveyor rollers of the roller conveyor via the support plate, the cartons are placed smoothly on the conveyor rollers. This method also eliminates the possibility of jamming during the connection stage of the transfer process and avoids the cartons shifting during the connection, thus improving the smoothness and accuracy of the connection.
