Description

Technical Field

[0001] The present invention belongs to the field of breeding equipment, and particularly relates to a depalletizer for breeding frames. Background Art

[0002] Silkworms, commonly known as silkworm babies, also called domestic silkworms, are one of the economic insects that spin cocoons by feeding on mulberry leaves. They belong to the order Lepidoptera and the family Bombycidae. The mulberry silkworm originated in China. Its development temperature is 7 - 40°C, and the suitable feeding temperature is 20 - 30°C. It is mainly distributed in temperate, subtropical and tropical regions.

[0003] The life cycle of a silkworm goes through silkworm eggs - newly hatched silkworms - silkworm babies - silkworm cocoons - silkworm moths, taking more than forty days in total. The newly hatched silkworm babies are dark in color and are called "newly hatched silkworms", covered with fine hairs, and the fine hairs become less obvious after about two days. After the newly hatched silkworms emerge from the eggs and are fed for a period of time, they begin to molt. The molting takes about one day and is called "dormancy". After one molt, they grow into second - instar larvae. The silkworm larvae need to molt four times and become fifth - instar larvae before they start to spin cocoons.

[0004] Domestic silkworm breeding generally uses small bamboo frames for breeding. These small frames have a simple structure, are easy to manufacture, can be hand - woven, and have a low cost. Silkworm breeding is a completely artificial breeding method, and from silkworm eggs to adult moths and then to collecting cocoons, all are achieved through manual operations. With the development of society, relying solely on domestic silkworm breeding cannot meet the demand for silk. Therefore, large - scale industrialized silkworm breeding has emerged. To adapt to industrialized silkworm breeding, it is necessary to manufacture supporting silkworm - breeding utensils. Among them, breeding frames are common breeding utensils. Since the number of breeding frames is large, frequent palletizing or depalletizing is required, especially depalletizing operations. Manual depalletizing has problems such as being time - consuming and laborious, having a large workload, and requiring a large amount of human resources, which is incompatible with high - efficiency industrialized silkworm breeding. Summary of the Invention

[0005] The purpose of the present invention is to provide a depalletizer for breeding frames used in industrialized breeding. In view of the problems in existing industrialized breeding, this depalletizer is designed and consists of a lifting mechanism, a pawl mechanism and a transverse movement mechanism. The lifting mechanism is used to drive the pawl mechanism to lift. During the lifting process, the pawl mechanism contacts the transverse movement mechanism at a set height, thereby pushing the entire transverse movement mechanism, causing the transverse movement mechanism to move horizontally to the designed position. At this designed position, the state of the pawl mechanism is adjusted, including the horizontal supporting state and the upward - tilting preparation state. In this way, the states of the pawl mechanism at various heights during the lifting process are ingeniously set, so as to complete the depalletizing operation one by one. This structural design is very ingenious and achieves the purpose of mechanical depalletizing.

[0006] To solve the above - mentioned technical problems, the following technical solutions are adopted:

[0007] A stacking-unloading machine for industrialized farming, comprising a frame and a stacking-unloading device mounted on the frame, characterized in that: the stacking-unloading device includes a lifting mechanism, a pawl mechanism and a transverse movement mechanism. The pawl mechanism is mounted on the lifting mechanism and is lifted by the lifting mechanism. The transverse movement mechanism acts on the pawl mechanism, and during the lifting process, the state of the pawl mechanism is adjusted through the transverse movement mechanism.

[0008] Furthermore, the lifting mechanism includes a lifting motor, a worm gear reducer and a transmission component. The lifting motor is connected to the worm gear reducer, and the worm gear reducer is connected to at least one group of transmission components. Each group of transmission components is connected to a pawl mechanism. The lifting motor can synchronously drive the two groups of transmission components to lift through the worm gear reducer, so as to realize the synchronous stacking-unloading operation of the two pawl mechanisms, improve the stability of the stacking-unloading operation, and reduce the probability of equipment failure. The transmission component is used to convert the rotational motion of the lifting motor into a lifting motion and drive the pawl mechanism to lift, which not only has stable transmission, but also enables the transmission component to obtain a reasonable and appropriate lifting speed.

[0009] Furthermore, the transmission component includes an adjusting part, a pedestal bearing, a swing shaft mounting part, a spherical plain bearing I, a spherical plain bearing II, a push rod and a jacking support. The rotating shaft extending from the worm gear reducer is connected to the adjusting part through the pedestal bearing. The swing shaft mounting part is installed in the hole of the adjusting part. The swing shaft mounting part is connected to the push rod through the spherical plain bearing I in an articulated manner. The push rod is articulated to the jacking support through the spherical plain bearing II. This transmission component converts the rotational motion into a linear lifting motion through the adjusting part, the swing shaft mounting part, the push rod and the articulated connection relationship, with a clever structural design and stable transmission.

[0010] Furthermore, the lifting mechanism also includes a guiding component, which includes a lifting slider and a lifting guide rod. The lifting slider slides on the lifting guide rod, and the lifting slider is fixedly connected to the pawl mechanism to guide the lifting action of the pawl mechanism. The lifting slider and the lifting guide rod play a guiding role in lifting, improve the stability of lifting, and avoid lifting deviation.

[0011] Furthermore, the pawl mechanism includes a pawl and a contact ball bearing. The contact ball bearing acts on the transverse movement mechanism and is used to push the transverse movement mechanism to move transversely. During the lifting process, the transverse movement mechanism adjusts the pawl to alternate back and forth between the horizontal supporting state and the upward-curling preparation state. During the lifting process, the contact ball bearing pushes the transverse movement mechanism at a set height to move it to a set position. At this set position, the state of the pawl during the rising and falling processes can be adjusted, and it alternates between the horizontal supporting state and the upward-curling preparation state; in this way, the state of the pawl at each height during the lifting process is cleverly set, so as to complete the stacking-unloading operation one by one. This structural design is very clever and achieves the purpose of mechanical stacking-unloading.

[0012] Furthermore, the claw includes a gripper, a bracket and a roller bearing. The bracket is fixed, the gripper is hinged to the bracket and is provided with a roller bearing. The transverse movement mechanism acts on the roller bearing. During the lifting process, the gripper is adjusted to change back and forth between a horizontal supporting state and an upward ready state. The bracket is used to install the gripper, and the gripper is rotatable through an articulated connection. The roller bearing can roll, which serves as a medium for the transverse movement mechanism to adjust the claw. The roller bearing rolls on the guide head through the roller bearing to achieve the purpose of driving the gripper to rotate and change states, avoiding collisions between components, preventing collision damage, and effectively preventing the occurrence of faults such as jamming.

[0013] Furthermore, the claw mechanism also includes a claw mounting plate for mounting the claw and the contact ball bearing. The claw mounting plate is a flat plate structure, the claw and the contact ball bearing are mounted on the front end, and the rear end is connected to the lifting support of the lifting mechanism and the lifting slider of the guide assembly, and has a simple structure and stable operation.

[0014] Furthermore, a through hole is provided at the position where the gripper is installed on the claw mounting plate, and a limit block is installed on the gripper, and the limit block matches the through hole. When the gripper is in a horizontal supporting state, the limit block enters the through hole and supports the upper end of the through hole, limiting the position of the gripper to prevent it from further rotating downward; when the gripper holds up the breeding frame, it is given a certain force to further improve the stability of the stacking.

[0015] Furthermore, the transverse movement mechanism includes a connected guide plate and a moving part, and the moving part moves transversely under the push of the contact ball bearing; the guide plate adjusts the claw to switch back and forth between the horizontal support state and the upward preparation state. The moving part is pushed by the contact ball bearing to move transversely, and the contact ball bearing pushes the moving part in opposite transverse directions at the high position and the low position. The pushing direction can be determined according to specific work requirements; after the moving part moves transversely, it drives the guide plate to move transversely synchronously, thereby moving the guide plate transversely to a set position, and at this set position, the state adjustment of the claw during lifting is completed. The transverse movement mechanism has a simple structure and a clever design, and uses the lifting action of the claw mechanism to complete the transverse movement without the need for cooperating with the transverse movement drive component.

[0016] Furthermore, the guide plate includes a guide head, which adjusts the claw to change back and forth between a horizontal supporting state and an upward ready state. The guide head is a plate inclined from the top to the breeding frame. During the rising process, the claw always maintains an upward state under the action of the guide head until it exceeds the height of the guide head. The claw changes from an upward state to a horizontal state, supporting the remaining breeding frames except the bottom breeding frame, so as to lift this part of the breeding frame and separate the bottom breeding frame. At the same time, after rising to a certain height, the guide head moves horizontally; during the descent process, the claw maintains a supporting state until it is lowered to the chain conveyor line, and the claw will change to an upward state again under the action of the guide head, and the guide head will move horizontally again to recover; with the help of the guide head, the claw can achieve the effect of destacking by cyclically changing its state. The structural design is ingenious.

[0017] Further, the guiding head includes a long guiding head and a short guiding head. The long guiding head adjusts the pawls during the ascending process, and the short guiding head adjusts the pawls during the descending process. The long guiding head and the short guiding head cooperate with each other. During the ascending process, the long guiding head can keep the pawls in an upturned state until the height of the second breeding frame at the bottom, so as to separate the bottom breeding frame; during the descending process, the short guiding head can make the pawls change to an upturned state after lowering the breeding frame. The structure is simple and can cleverly complete the palletizing operation.

[0018] Further, the moving part includes a moving frame body, an upper moving convex block and a lower moving convex block installed on the moving frame body. The moving frame body is connected to the guide plate. The contact ball bearing pushes the upper moving convex block at the upper end and the lower moving convex block at the lower end to control the lateral movement of the moving frame body and the guide plate. The upper moving convex block is installed at the upper end of the moving frame body, and the lower moving convex block is installed at the lower end of the moving frame body. When the contact ball bearing rises to the upper moving convex block, it drives the guide plate to move laterally by pushing the upper moving convex block, so that the pawls are aligned with the short guiding head in the vertical direction; when the contact ball bearing descends to the lower moving convex block, it drives the guide plate to move laterally and reset by pushing the lower moving convex block, so that the pawls are aligned with the long guiding head in the vertical direction. With the structural characteristics of the upper moving convex block and the lower moving convex block, the present invention realizes the pushing effect of the contact ball bearing on the moving part without the need to be equipped with a driving component.

[0019] Further, both the upper moving convex block and the lower moving convex block are trapezoidal, and they are respectively arranged at the front end and the rear end, and are pushed to move horizontally by the contact ball bearing. The trapezoidal moving convex block has an inclined surface. The contact ball bearing can slide on the inclined surface to achieve the pushing effect. The two push connections have no collision and the pushing process is smooth.

[0020] Further, the lateral movement mechanism further includes a sliding component. The sliding component includes a slider and a lateral movement guiding rod. The slider is connected to the guide plate and moves on the lateral movement guiding rod. The lateral movement guiding rod is installed on the frame. The slider can slide along the lateral movement guiding rod to play a guiding role in lateral movement, improve the stability of lateral movement, and the structure is simple and ingeniously designed.

[0021] Further, the sliding component further includes a slider mounting plate for mounting the slider, and the slider mounting plate is installed on the guide plate.

[0022] Further, the breeding frame palletizing machine further includes a chain conveyor line, and the breeding frame is fed through the chain conveyor line. On the one hand, the chain conveyor line feeds the palletized breeding frames and can sequentially and continuously split different groups of palletized breeding frames to improve the palletizing efficiency; on the other hand, it is used to send out the split breeding frames one by one to realize palletizing and achieve the purpose of automatic palletizing.

[0023] Due to the adoption of the above technical solutions, the following beneficial effects are achieved:

[0024] The present invention relates to a stacking frame unstacking machine for industrialized farming. In view of the problems in existing industrialized farming, this unstacking machine is designed and consists of a lifting mechanism, a claw mechanism, and a transverse movement mechanism. The lifting mechanism is used to drive the claw mechanism to lift. During the lifting process, the claw mechanism contacts the transverse movement mechanism at a set height, thereby pushing the entire transverse movement mechanism and causing the transverse movement mechanism to move horizontally to the designed position. At this designed position, the state of the claw mechanism is adjusted, including the horizontal support state and the upward-tilting preparation state. In this way, the states of the claw mechanism at various heights during the lifting process are ingeniously set, thus completing the unstacking operation one by one. The structural design is very ingenious and achieves the purpose of mechanical unstacking. Its specific beneficial effects are as follows:

[0025] 1. The unstacking working principle of the present invention is as follows: The stacked farming frames are sent into the unstacking machine through a chain conveyor line; at this time, the lifting mechanism drives the gripper to be at the lowest position, and the contact ball bearing pushes the lower moving convex block, causing the long guide head to be above the roller bearing; the lifting mechanism is activated, and the gripper rises. The roller bearing passes through the guide head, causing the gripper to always maintain an upward-tilting state during the rising process; after the roller bearing rises out of the guide head, the gripper changes to a horizontal state under the action of gravity and just inserts into the second farming frame from bottom to top; during the continuous rising process, all the above farming frames are gradually lifted. During the continuous rising process, the contact ball bearing gradually pushes the upper moving convex block, causing the short guide head and the roller bearing to be on the same vertical line; after the gripper reaches the highest position, the chain conveyor belt moves for a period of time to send away the lower farming frame, and then continues to pause; the lifting mechanism starts to descend, and the gripper first descends to the chain conveyor line and re-drops the stacked farming frames onto the chain conveyor line; then, under the action of the short guide head, the gripper is pushed up and tilted upward, and at the same time, the gripper continues to descend to the lowest position and resets the transverse movement mechanism horizontally. The guide head and the roller bearing are on the same vertical line, and the above process is repeated to disassemble the farming frames one by one from bottom to top.

[0026] Based on the above structure, the present invention completes the unstacking operation one by one. The structural design is very ingenious and achieves the purpose of mechanical unstacking.

[0027] 2. Regarding the lifting mechanism: The lifting motor can synchronously drive two sets of transmission components to lift through a worm gear reducer, thereby realizing the synchronous unstacking operation of two claw mechanisms, improving the stability of the unstacking operation, and reducing the probability of equipment failures. The transmission components are used to convert the rotational motion of the lifting motor into a lifting motion and drive the claw mechanism to lift. Not only is the transmission stable, but also the transmission components can obtain a reasonable and appropriate lifting speed.

[0028] 3. Regarding the pawl mechanism: During the lifting process, the contact ball bearing pushes the transverse movement mechanism at a set height, causing it to move transversely to the set position. At this set position, the state of the pawl during the ascending and descending processes can be adjusted, and it can be switched between the horizontal supporting state and the upward-tilting preparation state. In this way, the states of the pawl at various heights during the lifting process are ingeniously set, thereby completing the palletizing operation one by one. The structural design is very ingenious, achieving the purpose of mechanical palletizing.

[0029] 4. Regarding the transverse movement mechanism: The moving part is pushed by the contact ball bearing to move transversely. The transverse movement directions of the contact ball bearing at the high position and the low position are opposite, and this pushing direction can be determined according to specific working requirements. After the moving part moves transversely, it drives the guide plate to move transversely synchronously, thereby moving the guide plate to the set position. At this set position, the state adjustment of the pawl during lifting is completed. The structure of this transverse movement mechanism is simple and ingeniously designed. It borrows the power from the lifting action of the pawl mechanism to complete the transverse movement without the need to cooperate with a transverse movement driving component.

Detailed implementation mode

[0039] The present invention aims to provide a stacking frame unstacking machine for factory farming. In view of the problems in existing factory farming, the unstacking machine is designed and consists of a lifting mechanism, a pawl mechanism and a transverse movement mechanism. The lifting mechanism is used to drive the pawl mechanism to lift. During the lifting process, the pawl mechanism contacts the transverse movement mechanism at a set height, thereby pushing the entire transverse movement mechanism, causing the transverse movement mechanism to move horizontally to the designed position. At this designed position, the state of the pawl mechanism is adjusted, including the horizontal supporting state and the upward-tilting preparation state. In this way, the states of the pawl mechanism at various heights during the lifting process are ingeniously set, so as to complete the unstacking operation one by one. The structural design is very ingenious and achieves the purpose of mechanical unstacking.

[0040] The technical solution of the present invention will be elaborated in detail below in conjunction with the drawings and embodiments.

[0041] A stacking frame unstacking machine for factory farming includes a frame 1 and an unstacking device installed on the frame 1. The frame 1 is divided into a left frame 11, a right frame 12 and a middle cross frame 13. The frame 1 is installed on the chain conveyor line of the stacking frame. The chain conveyor line passes above the cross frame 13, and the stacking frame is fed through the chain conveyor line. On the one hand, the chain conveyor line feeds the stacked stacking frames, and can continuously split different stacked stacking frames in sequence, improving the unstacking efficiency; on the other hand, it is used to send out the split stacking frames one by one, realizing unstacking and achieving the purpose of automatic unstacking.

[0042] The unstacking device includes a mutually cooperating transverse movement mechanism 3, a lifting mechanism 4 and a pawl mechanism 2. A set of transverse movement mechanism 3 and pawl mechanism 2 are respectively installed on both sides of the frame 1. The pawl mechanisms 2 on both sides are driven by the same lifting mechanism 4 to lift. The transverse movement mechanism 3 and the pawl mechanism 2 act on each other, and during the lifting process, the state of the pawl mechanism 2 is adjusted through the transverse movement mechanism 3.

[0043] The lifting mechanism 4 includes a lifting motor 41, a worm gear reducer 42 and a transmission assembly. The lifting motor 41 is connected to the worm gear reducer 42. Both ends of the worm gear reducer 42 are connected to a set of transmission assemblies respectively, and each set of transmission assemblies is connected to a pawl mechanism 2. Specifically: The two sets of transmission assemblies are respectively installed on the left frame 11 and the right frame 12. The transmission assembly includes an adjusting member 43, a seat bearing 431, a swing shaft mounting member 433, a first spherical plain bearing 432, a second spherical plain bearing 441, a push rod 44 and a jacking support 45. The rotating shaft 421 extending from the worm gear reducer 42 is connected to the adjusting member 43 through the seat bearing 431. A swing shaft mounting member 433 is installed in the hole of the adjusting member 43. The swing shaft mounting member 433 is connected to the push rod 44 through the first spherical plain bearing 432 hinged thereto. The push rod 44 is hinged to the jacking support 45 through the second spherical plain bearing 441. The jacking support 45 is connected to the pawl mechanism 2 to transmit the lifting motion to the pawl mechanism 2, thereby driving the pawl mechanism 2 to lift. There are two sets of the pawl mechanisms 2 corresponding to the left and right, which are respectively located on the left frame 11 and the right frame 12, and the two work in synchronization.

[0044] The lifting motor 41 can drive the two sets of transmission assemblies to lift synchronously through the worm gear reducer 42, so as to realize the synchronous palletizing operation of the two pawl mechanisms 2, improve the stability of the palletizing operation, and reduce the probability of equipment failure. Through the adjusting member 43, the swing shaft mounting member 433, the push rod 44 and the hinged connection relationship, the transmission assembly converts the rotational motion into a linear lifting motion and drives the pawl mechanism 2 to lift, which not only has stable transmission, but also enables the transmission assembly to obtain a reasonable and appropriate lifting speed.

[0045] The lifting mechanism 4 further includes a guiding assembly 46. The guiding assembly 46 corresponds to the pawl mechanism 2 and is provided on both the left frame 11 and the right frame 12, and two sets are provided on each side. The guiding assembly 46 includes a lifting slider 461 and a lifting guide rod 462. The lifting slider 461 slides on the lifting guide rod 462, and the lifting slider 461 is fixedly connected to the pawl mechanism 2. The lifting guide rod 462 is fixedly installed on the left frame 11 or the right frame 12 to guide the lifting action of the pawl mechanism 2. The lifting slider 461 and the lifting guide rod 462 play a guiding role in lifting, improve the stability of lifting and prevent lifting deviation.

[0046] The pawl mechanism 2 includes a pawl mounting plate 22, pawls 21 and contact ball bearings 24. The pawl mounting plate 22 is of a flat plate structure, with the pawls 21 and contact ball bearings 24 mounted at the front end, and the rear end connected to the jacking support 45 of the lifting mechanism 4 and the lifting slider 461 of the guiding assembly 46. Its structure is simple and the operation is stable. There are two pawls 21 installed, one in the front and one in the rear (taking the feeding end of the breeding frame as the front and the discharging end of the breeding frame as the rear, the same below). The contact ball bearings 24 are located between the two pawls 21. The contact ball bearings 24 act on the transverse movement mechanism 3, by pushing the upper moving lug 322 and the lower moving lug 323 of the transverse movement mechanism 3, so as to achieve the purpose of pushing the transverse movement mechanism 3 at a set height, making it transversely move to a set position. At this set position, the state of the pawls 21 during the ascending and descending processes can be adjusted, and it can be transformed between the horizontal supporting state and the upward-tilting preparation state. In this way, the states of the pawls 21 at various heights during the lifting process are ingeniously set, thus completing the unstacking operation one by one. This structural design is very ingenious and achieves the purpose of mechanical unstacking.

[0047] The pawl 21 includes a claw 211, a bracket 212 and a roller bearing 213. The bracket 212 is fixedly installed on the pawl mounting plate 22, and the claw 211 is hinged between the brackets 212, enabling the claw 211 to rotate. Moreover, the claw 211 is provided with a roller bearing 213, and the roller bearing 213 can roll relative to the claw 211. The guiding head 34 of the transverse movement mechanism 3 acts on the roller bearing 213, and during the lifting process, the claw 211 is adjusted to transform back and forth between the horizontal supporting state and the upward-tilting preparation state. By rolling the roller bearing 213 on the guiding head 34, the purpose of driving the claw 211 to rotate and transform the state is achieved, avoiding collisions between components, preventing collision damage, and effectively eliminating the occurrence of faults such as jamming.

[0048] A through hole 23 is provided below the position where the pawl mounting plate 22 mounts the claw 211. A limiting block 214 is installed at the lower end of the claw 211, and the limiting block 214 is matched with the through hole 23. That is, when the claw 211 is in the horizontal supporting state, the limiting block 214 enters the through hole 23 and abuts against the upper end of the through hole 23, limiting the position state of the claw 211 and preventing it from further rotating downward. When the claw 211 lifts the breeding frame, a certain acting force is given to it, further improving the stability of unstacking.

[0049] The transverse movement mechanism 3 cooperates with the pawl mechanism 2 for operation and is installed on both the left frame 11 and the right frame 12. It includes a connected guide plate 31 and a moving member 32. The upper end of the guide plate 31 is provided with a guide head 34, and the guide head 34 corresponds one by one to the gripper 211. That is, there are two guide heads 34, front and back, on the same guide plate 31. The guide head 34 is a plate member inclined from top to the breeding frame direction. Each guide head 34 includes a long guide head 341 in the front and a short guide head 342 in the back. The moving member 32 includes a moving frame body 321, an upper moving bump 322 and a lower moving bump 323 installed on the moving frame body 321. The front end of the moving frame body 321 is connected to the guide plate 31, showing an inverted U-shaped structure. An upper moving bump 322 is provided above its interior, and a lower moving bump 323 is provided below. The upper moving bump 322 is in the front and the lower moving bump 323 is in the back. The contact ball bearing 24 moves up and down in the moving frame body 321.

[0050] When the contact ball bearing 24 rises to the upper end, it pushes the upper moving bump 322, and when it descends to the lower end, it pushes the lower moving bump 323 to control the transverse movement of the moving frame body 321 and the guide plate 31. During the ascending process of the pawl 21, the roller bearing 213 of the gripper 211 is aligned with the long guide head 341 in the vertical direction and always remains in the upturned state under the action of the long guide head 341 until it rises to a height exceeding that of the long guide head 341. The pawl 21 changes from the upturned state to the horizontal state, supporting the breeding frames except the bottom breeding frame, achieving the purpose of lifting this part of the breeding frames and separating the bottom breeding frame. The bottom breeding frame is sent out by the chain conveyor line. The pawl 21 continues to rise until the contact ball bearing 24 rises to the upper moving bump 322, driving the guide plate 31 to move forward transversely by pushing the upper moving bump 322, so that the roller bearing 213 of the gripper 211 is aligned with the short guide head 342 in the vertical direction. The pawl 21 starts to descend, maintaining the supporting state, and puts the breeding frame back on the chain conveyor line. After putting it back, the pawl 21 further descends and changes to the upturned state under the action of the short guide head 342. Then the contact ball bearing 24 descends to the lower moving bump 323, pushing the guide plate 31 to reset backward, and the roller bearing 213 of the gripper 211 is aligned with the long guide head 341 in the vertical direction again. With the aid of the structural characteristics of the upper moving bump 322 and the lower moving bump 323, the present invention realizes the pushing effect of the contact ball bearing 24 on the moving member 32, and the pawl 21 changes its state in a cycle during the ascending and descending process, achieving the effect of palletizing. This structural design is ingenious.

[0051] The long guide head 341 and the short guide head 342 cooperate with each other. During the ascending process, the long guide head 341 can keep the pawl 21 in the upturned state until the height of the second breeding frame from the bottom, thus separating the bottom breeding frame. During the descending process, the short guide head 342 can make the pawl 21 change to the upturned state again after putting down the breeding frame. The structure is simple and can ingeniously complete the palletizing operation.

[0052] The upper moving protrusion 322 and the lower moving protrusion 323 are both in a trapezoidal shape, and are respectively arranged at the front end and the rear end, and are pushed to move forward and backward by the contact ball bearing 24. The trapezoidal moving protrusion has an inclined surface, and the contact ball bearing 24 can slide on the inclined surface to achieve a pushing effect, and the two are pushed and connected without collision, and the pushing process is smooth.

[0053] The transverse movement mechanism 3 further includes a sliding assembly 33, which includes a slider mounting plate 333, a slider 332 and a transverse movement guide rod 331. The slider mounting plate 333 is connected to the guide plate 31. The slider 332 is provided with two front and rear sliders, both of which are mounted on the slider mounting plate 333 and move on the transverse movement guide rod 331. The transverse movement guide rod 331 is mounted on the frame 1. The slider 332 can slide along the transverse movement guide rod 331, play a guiding role in transverse movement, and improve the stability of transverse movement. The structure is simple and the design is ingenious.

[0054] The working process of destacking of the present invention is as follows:

[0055] 1. The stacked breeding frames are sent into the depalletizer through the chain conveyor line;

[0056] 2. At this time, the lifting mechanism 4 drives the gripper 211 to the lowest position. Under the action of the guide head 34, the gripper 211 is in an upward state, and the contact ball bearing 24 pushes the moving protrusion 323 downward, so that the transverse movement mechanism 3 moves horizontally to the rear end, and the long guide head 341 is aligned with the roller bearing 213 on the vertical line.

[0057] 3. The lifting mechanism 4 is started, the gripper 211 rises, and the roller bearing 213 passes through the guide head 34, so that the gripper 211 keeps the upward state during the rising process; after the roller bearing 213 rises and separates from the guide head 34, the gripper 211 changes to a horizontal state under the action of gravity and is just inserted into the second breeding frame from bottom to top;

[0058] 4. The gripper 211 gradually lifts up all the above breeding frames while continuing to rise. At the same time, the breeding frames at the bottom are sent out by the chain conveyor line, and the chain conveyor line is suspended after being sent out.

[0059] 5. When the contact ball bearing 24 rises to the highest position, the upper movable protrusion 322 is gradually pushed, and the transverse movement mechanism 3 moves toward the front end, so that the roller bearing 213 of the gripper 211 and the short guide head 342 are on the same vertical line.

[0060] 6. The lifting mechanism 4 starts to drive the gripper 211 to descend. During the descent, the gripper 211 maintains a horizontal supporting state and lowers the breeding frame onto the chain conveyor line.

[0061] 7. The lifting mechanism 4 continues to drive the gripper 211 to descend. When it descends to the short guide head 342, the short guide head 342 lifts the gripper 211, and the gripper 211 tilts upward and leaves the supporting state.

[0062] 8. The lifting mechanism 4 drives the gripper 211 to descend to the lowest position, gradually pushing the downward moving convex block 323, and the transverse movement mechanism 3 moves backward. The roller bearing 213 of the gripper 211 and the long guide head 341 are on the same vertical line.

[0063] 9. Repeat steps 3 - 9 to disassemble the breeding frames one by one from bottom to top.

[0064] 10. After the disassembling of the breeding frames in this palletizing is completed, repeat steps 1 - 9 to disassemble the breeding frames of the next palletizing group.

[0065] In addition, the depalletizer of the present invention is also provided with a touch screen, various function buttons and a waterproof multi - layer warning light:

[0066] The depalletizer can be controlled through the touch screen, which is convenient for operation.

[0067] Various function buttons achieve their specific functions.

[0068] The waterproof multi - layer touch screen provides a waterproof alarm function.

[0069] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present invention.
