Description

Technical Field

[0001] This utility model relates to the field of logistics equipment technology, and in particular to an all-electric drive pallet converter system. Background Technology

[0002] Chinese invention patent CN105109976A, entitled "An Automatic Pallet Changer Based on PLC Control," describes a device that uses a PLC-controlled hydraulic system to drive a mechanical mechanism. However, the hydraulic system requires an additional hydraulic source, is prone to liquid leakage, is unsuitable for high and low temperature environments, and is cumbersome to maintain. Therefore, a novel pallet changer was designed to address this problem. Utility Model Content

[0003] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide an all-electric drive tray converter system.

[0005] To achieve the above objectives, the technical solution of this utility model is: an all-electric drive tray converter system, including a base, a rotating base rotatably connected to the base, a rotation drive mechanism for driving the rotating base to rotate, two clamping arms slidably connected to the upper and lower ends of the rotating base, a clamping arm drive mechanism for driving the two clamping arms to move in opposite directions, a tray fixing mechanism for the lower clamping arm, a side door for one side of the rotating base, the side door rotatably connected to the rotating base, and a side door drive mechanism for driving the side door to rotate. The rotation drive mechanism, clamping arm drive mechanism, tray fixing mechanism, and side door drive mechanism are all driven by motors.

[0006] By adopting the above technical solution, the converter first opens the side door through the side door drive mechanism, then places the material and pallet onto the clamping arm located at the bottom. The side door drive mechanism then closes the side door, the pallet fixing mechanism fixes the pallet, and the clamping arm drive mechanism drives the two clamping arms to clamp the material. The rotation drive mechanism drives the rotating base to rotate 180°, causing the pallet to be replaced at the top of the logistics. Then the clamping arms release the material. At this time, the pallet, fixed by the pallet fixing mechanism and driven by the clamping arms, separates from the material. After the sub-pallet is placed in, it is clamped again and the rotating base is rotated. After the clamping is released, the replaced material and pallet are taken out. All the above drive mechanisms are driven by motors, making the pallet changer more widely applicable, eliminating the need for maintenance and upkeep of hydraulic components, making maintenance simpler, and the all-electric drive has a fast response and reduces the transmission mechanism.

[0007] Preferably, the rotary drive mechanism includes a rotary motor, an internal gear, and a slewing support. The slewing support is fixedly connected to the base, sleeved on the outside of the internal gear, and the internal gear is rotatably connected to the slewing support. The rotary motor is drive-connected to the internal gear, and the internal gear is drive-connected to the rotating base. This invention uses the output gear on the rotary motor to drive the internal gear, thereby providing power for the rotation of the rotating base. The slewing support is a bearing-like mechanism, with its ball bearings contacting the internal gear to reduce wear during rotation.

[0008] Preferably, the clamping arm driving mechanism includes an electric cylinder, the output rod of which is tractively connected to one of the clamping arms, and the two clamping arms are tractively connected to each other through a transmission mechanism. This invention utilizes the extension and retraction of the electric cylinder output rod to drive one of the clamping arms, and then uses the transmission mechanism to drive the other clamping arm to slide in the opposite direction, thereby driving both clamping plates.

[0009] Preferably, the transmission mechanism includes two chains and two sprockets. Both ends of the two chains are respectively connected to the two clamping arms, and both sprockets are rotatably connected to the rotating base. The two chains mesh with the two sprockets. This invention utilizes the cooperation of two chains and two sprockets to achieve the transmission connection between the two clamping arms.

[0010] Preferably, the pallet fixing mechanism includes a plurality of hooks, which are rotatably connected to both sides of the clamping arm located at the bottom. Each side of the clamping arm is provided with two sets of hook drive mechanisms for driving the hooks to rotate. This invention utilizes the hook drive mechanisms to drive the rotation of all components, thereby enabling the pallet to be gripped and fixed.

[0011] Preferably, the hook drive mechanism includes a linkage shaft and a hook drive motor. Each hook located on the same side is driven by the linkage shaft, the linkage shaft is driven by the hook motor, and the hook motor is fixedly connected to the clamping arm. This invention utilizes the linkage shaft to connect all hooks in series, and the hook motor drives the linkage shaft to rotate, thereby driving the hooks.

[0012] Preferably, the side door drive mechanism includes a rotating rod and a side door motor. The rotating rod is rotatably connected to the side door and is also drively connected to the side door. The side door motor is fixedly connected to the rotating base and is also drively connected to the rotating rod. This invention utilizes the side door motor to drive the rotating rod to rotate, thereby driving the side door.

[0013] Preferably, the clamping arm at the top is equipped with a roller conveyor assembly, which is driven by a roller conveyor drive motor. This invention utilizes the roller conveyor assembly to provide transport power to the top of the material, facilitating material loading and unloading from the converter.

[0015] Preferably, the base is fixedly connected to a limiting post, and the present invention limits the travel of the bottom clamping arm by means of the limiting post.

[0016] In summary, the beneficial effects of this utility model are:

[0017] 1. It expands the application range of pallet changers, eliminates the need for maintenance and upkeep of hydraulic components, making maintenance simpler, and features fast response due to its all-electric drive, reducing the need for transmission mechanisms.

[0033] like Figure 1-3 As shown, an all-electric drive tray converter system includes a base 1, a rotating base 2 rotatably connected to the base 1, a rotary drive mechanism for driving the rotating base 2 to rotate, two clamping arms 3 slidably connected to the upper and lower ends of the rotating base 2, a clamping arm drive mechanism for driving the two clamping arms 3 to move in opposite directions, a tray fixing mechanism for the lower clamping arm 3, and a side door 4 rotatably connected to the rotating base 2 on one side, a side door drive mechanism for driving the side door 4 to rotate. The rotary drive mechanism, clamping arm drive mechanism, tray fixing mechanism, and side door drive mechanism are all driven by motors.

[0034] By adopting the above technical solution, when the converter is working, the side door 4 is first opened by the side door drive mechanism, and then the material and pallet are placed on the clamping arm 3 located at the bottom. Then the side door drive mechanism closes the side door 4, the pallet fixing mechanism fixes the pallet, the clamping arm drive mechanism drives the two clamping arms 3 to clamp the material, and the rotation drive mechanism drives the rotating base 2 to rotate 180° so that the pallet is replaced to the top of the logistics. Then the clamping arm 3 releases the material. At this time, the pallet is separated from the material by the clamping arm 3 driven by the pallet fixing mechanism. Then the sub-pallet is put in and clamped again and the rotating base 2 is rotated. After the clamping is released, the replaced material and pallet are taken out. All the above drive mechanisms are driven by motors, which makes the pallet changer more widely used, eliminates the maintenance and upkeep of hydraulic components, makes maintenance simpler, and the all-electric drive has a fast response and reduces the transmission mechanism.

[0035] The rotary drive mechanism includes a rotary motor 5, an internal gear 6, and a rotary support 7. The rotary support 7 is fixedly connected to the base 1 and is sleeved on the outside of the internal gear 6. The internal gear 6 is rotatably connected to the rotary support 7. The rotary motor 5 is driven by the internal gear 6, and the internal gear 6 is driven by the rotating base 2. The output gear on the rotary motor 5 is driven by the internal gear 6, which rotates the internal gear 6, thus providing power for the rotation of the rotating base 2. The rotary support 7 is a bearing-like mechanism, with its balls contacting the internal gear 6 to reduce wear during rotation.

[0036] The clamping arm drive mechanism includes an electric cylinder 8. The output rod of the electric cylinder 8 is connected to one of the clamping arms 3, and the two clamping arms 3 are connected to each other through a transmission mechanism. The extension and retraction of the output rod of the electric cylinder 8 drives one of the clamping arms 3, and then the transmission mechanism drives the other clamping arm 3 to slide in the opposite direction, thereby driving the two clamping plates.

[0037] The transmission mechanism includes two chains 9 and two sprockets 10. Both ends of the two chains 9 are connected to the two clamping arms, and both sprockets 10 are rotatably connected to the rotating base. The two chains 9 mesh with the two sprockets 10. The transmission connection between the two clamping arms is achieved through the mutual cooperation of the two chains 9 and the two sprockets 10.

[0038] The pallet securing mechanism includes several hooks 11, which are rotatably connected to both sides of a clamping arm 3 located at the bottom. Each side of the clamping arm 3 is equipped with two sets of hook drive mechanisms for driving the hooks 11 to rotate. By utilizing the hook drive mechanisms to rotate the entire process, the pallet can be gripped and secured.

[0039] The hook drive mechanism includes a linkage shaft 12 and a hook drive motor. Each hook 11 located on the same side is driven by the linkage shaft 12, and the linkage shaft 12 is driven by the hook 11 motor. The hook 11 motor is fixedly connected to the clamping arm 3. The linkage shaft 12 connects all the hooks 11 in series, and the linkage shaft 12 is driven to rotate by the hook 11 motor, thereby driving the hooks 11.

[0040] The side door drive mechanism includes a rotating rod 13 and a side door motor. The rotating rod 13 is rotatably connected to the side door and is also driveably connected to the side door 4. The side door motor is fixedly connected to the rotating base 2 and is also driveably connected to the rotating rod 13. The side door motor drives the rotating rod 13 to rotate, thereby driving the side door.

[0041] The clamping arm 3 at the top is equipped with a roller conveyor assembly 15, which is driven by a roller drive motor. The roller conveyor assembly 15 provides the power to transport the top of the material, facilitating the loading and unloading of the material from the converter.

[0042] The clamping arm 3 at the bottom is equipped with a chain conveyor assembly 16, which is driven by a chain drive motor. The chain conveyor assembly 16 provides power for transporting materials from the bottom, facilitating material loading and unloading from the converter.

[0043] The base 1 is fixedly connected to the limiting post 17, which limits the stroke of the bottom clamping arm 3.

[0044] In summary, the working principle of this utility model is as follows: When the converter is working, the side door 4 is first opened by the side door drive mechanism, and then the material and pallet are placed on the clamping arm 3 located at the bottom. Then the side door drive mechanism closes the side door 4, the pallet fixing mechanism fixes the pallet, the clamping arm drive mechanism drives the two clamping arms 3 to clamp the material, and the rotation drive mechanism drives the rotating base 2 to rotate 180° so that the pallet is replaced to the top of the logistics. Then the clamping arm 3 releases the material. At this time, the pallet is separated from the material by the clamping arm 3 because it is fixed by the pallet fixing mechanism. Then the sub-pallet is put in and clamped again and the rotating base 2 is rotated. After the clamping is released, the replaced material and pallet are taken out.

[0045] It should be noted that many specific details have been set forth in the above description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
