[0003] In the process of stacking feed bags, since the material in the bag can flow, the above-mentioned rotary joint robot stacking device and an automatic stacking device for bagged feed are used to stack the feed bags. The robot's grasping action is likely to cause the feed bags to deform, and the feed bags fall onto the pallet in a free-falling manner, making it difficult to ensure that the bag body is in a flat state, resulting in uneven flatness of each layer and the entire stacking being very unstable. During transportation, the feed bags are prone to slide. Based on this, the existing stacking device has the problem of uneven stacking bags, which is very inconvenient to use and needs to be solved urgently. Summary of the invention

[0004] The purpose of the present invention is to solve the defect of uneven stacking bags in the existing stacking device in the prior art, and to propose an intelligent stacking and transporting device for feed bags.

[0014] The present invention has the following beneficial effects:

[0015] 1. The stacking and transferring equipment proposed in the present invention arranges a plurality of material bags in a rectangular array on the inclined plate by setting an inclined plate and a rolling shaft, and utilizes a material pushing assembly. During the process of arranging the material bags, the rolling shaft can flatten the surface of the material bags, and the arranged material layers slide along the surface of the inclined plate and are stacked on the pallet in layers, thus solving the problems of uneven stacking and unstable stacking of bags. In this method, each material layer is regarded as a stacking unit. Compared with bag-by-bag stacking, the number of reciprocating translations of the mobile frame is reduced, the idle movement time is reduced, and the stacking efficiency is higher.

[0016] 2. The stacking and transferring equipment proposed by the present invention is provided with pusher components on both sides of the mobile frame. The pusher components on one side can arrange the material bags horizontally on the inclined plate to form a lower material layer, and the pusher components on the other side can arrange the material bags vertically on the inclined plate to form an upper material layer. The upper material layer is stacked on the upper side of the lower material layer. The material bags of the upper and lower layers are arranged alternately vertically and horizontally. The material bags are stacked together in an interlaced manner. Under the action of the friction between each other, the stacking is more stable, which further improves the stability of the stacking;

[0017] 3. The stacking and transferring equipment proposed in the present invention is provided with opposite pushing plates on both sides of the mobile frame. When the pushing plates push the material bags to move, the pushing plates on both sides provide lateral pressure for the material bags. Since the inclined plates are in an inclined state, when the material bags slide along the inclined plates, the weight of the material bags themselves is utilized to provide lateral pressure for the material bags to approach each other, thereby reducing the gap between the bags, making the stacking more concentrated, facilitating the control of the neatness of the stacking, and preventing the edges of the material bags from extending to the outside of the pallet or dragging on the ground.

[0018] 4. The stacking and transferring equipment proposed by the present invention is provided with an adjusting cylinder between the telescopic end of the hydraulic cylinder and the inclined plate. The excitation coil in the adjusting cylinder provides magnetic repulsion or magnetic attraction for the magnetic column. The extension and retraction movement of the magnetic column drives the inclined plate to vibrate. At the same time, the distance between the inclined plate and the rolling shaft varies, which is conducive to the material bag sliding into the arrangement cavity. Its vibration promotes the flow of material in the bag and makes the material bag stretch into a flat state. Since the force of the excitation coil on the magnetic column is adjustable and a contact sensor is arranged in the adjusting cylinder, when the material bag feeding on the inclined plate reaches a preset number, the hydraulic cylinder is started and contracted only after the magnetic column presses and triggers the contact sensor, so that the inclined plate flips downward to discharge the material. This is conducive to monitoring whether the number of material bags in each material layer meets the requirements, avoiding the occurrence of bag shortage, and providing conditions for automatic stacking.

[0032] Two guide plates are fixedly installed on the upper surface of the inclined plate 3. The two guide plates and the two side plates of the movable frame 2 constitute the first feed port 23 and the second feed port 24. The outlet end of the first chain conveyor 21 is arranged on the upper side of the first feed port 23, and the outlet end of the second chain conveyor 22 is arranged on the upper side of the second feed port 24.

[0033] Among them, the mobile frame 2 is composed of two side plates, and the two side plates are fixedly connected to the two ends of the guard beam 4 respectively. A T-shaped slide groove is opened on the upper surface of the mounting platform 1, and multiple guide wheels 8 are rotatably installed on the lower surfaces of the two side plates. A driving assembly is arranged in the T-shaped slide groove, and the driving assembly drives the mobile frame 2 to reciprocate and translate along the T-shaped slide groove, and the guide wheel 8 rolls along the T-shaped slide groove.

[0034] Specifically, the driving assembly includes a servo motor 9 and a transmission screw 10. The transmission screw 10 is rotatably installed on the upper side of the mounting platform 1. The servo motor 9 is fixedly installed at the end of the mounting platform 1. The servo motor 9 drives the transmission screw 10 to rotate. A connecting sleeve 11 is fixedly installed on the lower side of the movable frame 2. The transmission screw 10 is threadedly connected to the connecting sleeve 11. When the servo motor 9 drives the transmission screw 10 to rotate forward or reversely, it drives the movable frame 2 to move toward the upper side of the support plate 26, or move away from the support plate 26.

[0035] Several parallel rolling shafts 6 are rotatably installed inside the mobile frame 2, and an arrangement cavity is formed between the rolling shafts 6 and the inclined plate 3. The material bags 7 conveyed by the conveyor fall into the arrangement cavity, and the pushing assembly pushes the material bags 7 to move and places several material bags 7 in a rectangular array in the arrangement cavity.

[0036] A crossbeam 12 is fixedly installed inside the mobile frame 2, one end of the rolling shaft 6 is rotatably connected to the crossbeam 12, and the other end of the rolling shaft 6 is rotatably connected to the stop beam 4. When the upper surface of the inclined plate 3 is pressed against the lower surface of the stop beam 4, the distance from the lower end of the rolling shaft 6 to the inclined plate 3 is smaller than the distance from the upper end of the rolling shaft 6 to the inclined plate 3. Figure 3 The distance from the upper end of the rolling shaft 6 to the inclined plate 3 is large, which facilitates the material bag 7 to slide into the arrangement cavity.

[0037] Both sides of the mobile frame 2 are provided with a push assembly, refer to Figure 5 , Figure 6 The pusher assembly includes a mounting cover 13, which is fixedly connected to the side plate of the movable frame 2. A pusher plate 14 is slidably arranged inside the mounting cover 13. A hydraulic push rod 15 is fixedly installed on the surface of the mounting cover 13. The hydraulic push rod 15 drives the pusher plate 14 to move so that the pusher plate 14 can extend into the interior of the arrangement cavity.

[0038] In this embodiment, the distance between the two side plates of the mobile frame 2 is greater than the length of any side of the upper surface of the support plate 26, and the length of the push plate 14 is greater than the length of any side of the upper surface of the support plate 26. The push plate 14 can push multiple material bags 7 to move at the same time. By adjusting the telescopic length of the hydraulic push rod 15 and controlling the distance between the push plates 14 on both sides, the stacking area of ​​the material bags 7 can be adjusted as needed to meet the stacking requirements of material bags 7 of different sizes.

[0039] During use, the material bags 7 conveyed by the first chain conveyor 21 are placed horizontally. Figure 5 As shown in the material bag 7 at A in the middle, the material bag 7 slides along the inclined plate until it is blocked by the stop beam 4, and multiple material bags 7 are discharged in a row on the upper surface of the inclined plate 3. The first chain plate conveyor 21 stops running, and the hydraulic push rod 15 extends, and the push plate 14 pushes away the above-mentioned row of material bags 7, so that the push plate 14 is reset to leave a gap, and then the first chain plate conveyor 21 is started to feed materials, and the second row of material bags 7 are discharged at the above-mentioned gap, and the push plate 14 pushes away the two rows of material bags 7 together. Figure 5 As shown by the arrow in the middle, the cycle continues until a rectangular array of material layers is arranged on the inclined plate 3. Figure 7 The same as the lower material layer 27;

[0040] refer to Figure 3 , the hydraulic cylinder 5 contracts, the inclined plate 3 flips downward at a certain angle, at this time the inclined plate 3 is separated from the stop beam 4, and at the same time, the mobile frame 2 moves away from the support plate 26, and the material layer on the inclined plate 3 slides onto the support plate 26. Figure 7 As shown, the lower material layer 27 is formed by laying flat on the support plate 26;

[0041] The material bags 7 conveyed by the second chain conveyor 22 are placed vertically. Figure 6 As shown in the material bag 7 at B in the figure, the material bag 7 slides along the inclined plate until it is blocked by the stop beam 4, and multiple material bags 7 are discharged in a row on the upper surface of the inclined plate 3. The second chain plate conveyor 22 stops running, and the hydraulic push rod 15 extends. The push plate 14 pushes away the above-mentioned row of material bags 7, so that the push plate 14 is reset to leave a gap, and then the second chain plate conveyor 22 is started to feed materials, and the second row of material bags 7 are discharged at the above-mentioned gap. The push plate 14 pushes away the two rows of material bags 7 together. Figure 6 As shown by the arrow in the middle, the cycle continues until a rectangular array of material layers is arranged on the inclined plate 3. Figure 7 The upper material layer 28 is the same;

[0042] refer to Figure 3 , start the scissor lift platform 25, lower the height of the support plate 26 and keep it, and drive the inclined plate 3 to flip down a certain angle by contracting the hydraulic cylinder 5. At this time, the inclined plate 3 is separated from the stop beam 4. At the same time, the mobile frame 2 moves away from the support plate 26, and the material layer on the inclined plate 3 slides down. Figure 7 As shown, the upper material layer 28 is laid flat on the upper side of the lower material layer 27. It should be emphasized that the material bags 7 of the lower material layer 27 are placed horizontally, and the material bags 7 of the upper material layer 28 are placed vertically;

[0043] Repeat the above operation to stack multiple layers of material bags 7 on the pallet 26, and then use a forklift to transport the pallet 26.

[0044] By respectively arranging pushing components on both sides of the mobile frame 2, the pushing component on one side can arrange the material bags 7 horizontally on the inclined plate 3 to form a lower material layer 27, and the pushing component on the other side can arrange the material bags 7 vertically on the inclined plate 3 to form an upper material layer 28. The upper material layer 28 is stacked on the upper side of the lower material layer 27. The material bags 7 of the upper and lower layers are arranged alternately vertically and horizontally, and the material bags 7 are staggered and stacked together. Under the action of the friction between each other, the stacking is more stable.

[0045] Relative pushing plates 14 are arranged on both sides of the mobile frame 2. When the pushing plates 14 push the material bags 7 to move, the pushing plates 14 on both sides provide lateral pressure for the material bags 7. Since the inclined plate 3 is in an inclined state, when the material bags 7 slide along the inclined plate 3, the weight of the material bags 7 themselves is utilized to provide lateral pressure for the material bags 7 to approach each other, thereby reducing the gap between the bags, making the stacking more concentrated, facilitating the control of the neatness of the stacking, and preventing the edges of the material bags 7 from extending to the outside of the support plate 26 or dragging on the ground.

[0046] The stacking and transferring equipment proposed by the present invention arranges a plurality of material bags 7 in a rectangular array on the inclined plate 3 by setting an inclined plate 3 and a rolling shaft 6, and uses a material pushing assembly to arrange the material bags 7 in a rectangular array. Figure 8 As shown, the rolling shaft 6 can flatten the surface of the material bag 7, and the arranged material layers slide along the surface of the inclined plate 3 and are stacked on the pallet 26 in layers, which solves the problems of uneven stacking of bags and unstable stacking. In this method, each material layer is regarded as a stacking unit. Compared with bag-by-bag stacking, the number of reciprocating translations of the mobile frame 2 is reduced, the idle movement time is reduced, and the stacking efficiency is higher.

[0047] In this embodiment, reference Figure 2 , Figure 4 An adjusting cylinder 16 is fixedly installed at the telescopic end of the hydraulic cylinder 5, a magnetic column 17 is slidably installed inside the adjusting cylinder 16, a connecting rod 29 extending to the outside of the adjusting cylinder 16 is fixedly installed at the end of the magnetic column 17, and one end of the connecting rod 29 away from the adjusting cylinder 16 is rotatably connected to the lower surface of the inclined plate 3, a supporting spring 18 is arranged inside the adjusting cylinder 16 to press against the magnetic column 17, and an excitation coil 19 is embedded inside the adjusting cylinder 16.

[0048] A contact sensor 20 is fixedly installed inside the adjustment cylinder 16 , and the sensing end of the contact sensor 20 faces the end of the magnetic column 17 .

[0049] During use, the excitation coil 19 is energized to generate a magnetic repulsion force F1 that repels the magnetic column 17. The elastic force of the support spring 18 on the magnetic column 17 is F2. The directions of F1 and F2 are consistent. When F1+F2 is greater than the force of the gravity of the material on the inclined plate 3 on the magnetic column 17, the connecting rod 29 is pushed out to make the upper surface of the inclined plate 3 press against the lower surface of the retaining beam 4. It should be noted that this is only a brief description, ignoring the weight of the inclined plate 3 itself and the direction of the material gravity. When the inclination angle of the inclined plate 3 is known, the force of the inclined plate 3 on the magnetic column 17 can be converted. This part belongs to the common knowledge of force decomposition calculation and will not be introduced here.

[0050] When the direction of the current introduced into the excitation coil 19 changes, the magnetic attraction force F3 that attracts the magnetic column 17 is in opposite directions. F3+F2 will be smaller than the force exerted by the gravity of the material on the inclined plate 3 on the magnetic column 17, and the inclined plate 3 will flip away from the retaining beam 4. When the magnitude or direction of the current introduced into the excitation coil 19 is changed, F1 and F3 will also change accordingly, which can drive the inclined plate 3 to vibrate back and forth.

[0051] Reduce the size of F1. With the feeding of the first chain conveyor 21 or the second chain conveyor 22, the amount of material on the inclined plate 3 increases, the gravity gradually increases, and the support spring 18 is compressed, so that the magnetic column 17 approaches the contact sensor 20. When the material bag 7 on the inclined plate 3 has fed a preset amount, the magnetic column 17 just touches the contact sensor 20. If the number of bags of material on the inclined plate 3 is not enough and the total weight is not enough, the magnetic column 17 cannot touch the contact sensor 20. When the contact sensor 20 is not triggered, the contraction of the hydraulic cylinder 5 is limited to prevent the inclined plate 3 from unloading prematurely.

[0052] The stacking and transferring equipment proposed by the present invention adds an adjusting cylinder 16 between the telescopic end of the hydraulic cylinder 5 and the inclined plate 3. The excitation coil 19 in the adjusting cylinder 16 provides magnetic repulsion or magnetic attraction for the magnetic column 17. The extension and retraction of the magnetic column 17 drives the inclined plate 3 to vibrate. At the same time, the distance between the inclined plate 3 and the rolling shaft 6 varies, which is conducive to the material bag 7 sliding into the arrangement cavity. Its vibration promotes the flow of material in the bag, so that the material bag 7 stretches into a horizontal state. Since the force of the excitation coil 19 on the magnetic column 17 is adjustable and a contact sensor 20 is arranged in the adjusting cylinder 16, when the material bag 7 on the inclined plate 3 The feeding reaches a preset number, the magnetic column 17 presses and triggers the contact sensor 20, and the hydraulic cylinder 5 is started and retracted to make the inclined plate 3 flip downward and discharge the material. This is conducive to monitoring whether the number of material bags 7 in each material layer meets the requirements, avoiding the occurrence of bag shortages, and providing conditions for automatic stacking.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
