[0011] S1: Start the material receiving device. The material receiving device transports the first layer of materials to below the upward material pushing device, and the detection device ensures that the first layer of materials is transported in place.

[0012] S2: The upward material pushing device moves towards the direction close to the material container. At the same time, the lifting device drives the material container to rise. The upward material pushing device contacts the first layer of materials and pushes the first layer of materials into the material container.

[0016] Further, S1 includes the following steps:

[0017] S11: Assume the total amount of packaging material is Z, the number of materials to be packaged is D, and the number of packaged materials is Y, where Z = D + Y;

[0018] S12: According to the size of the material container and the material size, determine the number of packaging materials per layer N and the stacking layers F. Among them, assume the length of the material container is H, the length dimension of the material is L, and the width dimension of the material is W. The detection device is arranged in P columns in the transportation track direction of the material receiving device, P ≥ ROUNG DOWN (H / W, 0), and P ≥ N;

[0019] S13: According to the material size, determine the number M ≥ ROUNG UP (L / W, 0) of the detection device arranged in the transportation track direction of the upward material pushing device;

[0020] S14: Assume the number of materials pushed per layer is C. When D / N ≥ 1, at this time C = P, and signals need to be detected by P columns of detection devices. At the same time, each column in the C columns has ≥ M - 1 detection devices detecting the material;

[0021] S15: When D / N < 1, at this time C = D, and signals need to be detected by D columns of detection devices. At the same time, check whether each column in the C columns has ≥ M - 1 detection devices detecting the material.

[0022] Further, S4 includes the following steps:

[0023] S41: When the value of Y increases by M, the value of D decreases by M, and the value of F subtracts 1, start the material receiving device, and the upward material pushing device moves away from the material container;

[0024] S42: When D > 0 and at the same time F > 0, the lifting device descends one layer;

[0025] S43: When D > 0 and at the same time F ≤ 0, the lifting device descends to the low position, and the downward material pushing device starts;

[0026] S44: When D ≤ 0, each device stops working.

[0027] The advantages and positive effects of the present invention are:

[0028] 1. The structure of the present invention is simple and easy to operate. Materials are transported through the material receiving device, and the detection device ensures that the materials are transported in place. The upper pusher device pushes the materials of this layer into the material container. After the upper pusher device rises and returns to its original position, at the same time, the material receiving device starts to transport the next batch of materials. During the above process, the lifting device descends layer by layer as the height of the materials in the material container changes until the material container is full. Then, the lower pusher device is started to push away the materials in the material container for overall packaging. Through the cooperation of the above devices, the equipment realizes the cyclic and rapid packaging of the incoming materials, achieves the parallel mode of the pushing and stacking return action and the material transportation action, effectively improves the efficiency of the pushing and stacking work, and the operation efficiency is increased by 30% compared with the serial pushing and stacking method, with high packaging efficiency.

[0029] 2. The material receiving device of the present invention drives the driving shaft to rotate through the driving motor. The driving shaft drives the conveyor belt to rotate, and the conveyor belt drives the driven shaft to rotate. The materials are placed on the conveyor belt, and the materials are transported through the cyclic movement of the conveyor belt. A material blocking and positioning device is provided at the end of the material receiving device to prevent the materials from falling off. The material receiving device has a simple structure and low production cost, and is suitable for popularization and application.

[0030] 3. The present invention uses diffuse reflection infrared sensors to detect whether the materials are transported to the transportation track of the upper pusher device. The diffuse reflection infrared sensors are respectively arranged in the transportation direction of the material receiving device and the transportation direction of the upper pusher device to avoid false detection caused by material deviation. It has high detection accuracy, is beneficial to the subsequent automatic regular pushing and stacking of materials, has a simple structure, low manufacturing cost, and high cost performance.

[0031] 4. In the upper pusher device of the present invention, the upper pusher plate is connected through a swing cylinder. The swing cylinder is installed at an angle with the sliding platform. When the swing cylinder extends, the upper pusher plate descends to contact the materials for pushing operation. When the swing cylinder contracts, the upper pusher plate rises above the materials and returns to the initial state to prepare for the next pushing operation. During the return process of the upper pusher plate, the lower material receiving device works normally to ensure that the two are carried out simultaneously, improving the work efficiency.

[0032] 5. An anti-clamping device is installed on the lower pusher device of the present invention. When the materials fall into the gap between the frame and the upper edge of the folding plate, when the lower telescopic cylinder drives the fixed plate to reciprocate, the reset part deforms to bend the folding plate, increasing the gap between the frame and the upper edge of the folding plate, avoiding mechanical failures caused by material jams and at the same time avoiding material damage. The connecting part can be set as a hinge, and the reset part can be set as a tension spring. It has a simple structure and low production cost, and is suitable for popularization and application.

[0033] 6. The equipment in the present invention can be flexibly customized according to the size of the upstream production line, is convenient to connect, has a simple process, a wide application range, and has high popularization value. Description of the Drawings

[0057] The following further describes the embodiments of the present invention with reference to the accompanying drawings:

[0058] As Figure 1 shown, an automatic boxing device includes a frame 1. A material receiving device 3 is provided on the upper surface of the frame 1. An upper pushing device 6 is provided above the material receiving device 3. The transportation trajectory of the material receiving device 3 is perpendicular to the transportation trajectory of the upper pushing device 6. A detection device 10 is provided on the material receiving device 3, and the detection device 10 ensures that the material receiving device 3 transports the material 7 to the lower part of the upper pushing device 6. A lower pushing device 2 is provided below the material receiving device 3, and the transportation trajectory of the lower pushing device 2 is parallel to the transportation trajectory of the upper pushing device 6. A material container 5 is provided at the tail end of the upper pushing device 6. The material container 5 is placed on a lifting device 4. During the descending process of the lifting device 4, the material container 5 receives the material 7 pushed down by the upper pushing device 6 layer by layer. When the lifting device 4 descends to the low position, the lower pushing device 2 works.

[0059] In this embodiment, the feeding device 3 transports the material 7, the detection device 10 ensures that the material 7 is transported in place, the upper pusher device 6 pushes this layer of material 7 into the material container 5, and the upper pusher device 6 rises and returns to its original position. At the same time, the feeding device 3 starts to transport the next batch of material 7. During the above process, the lifting device 4 descends layer by layer as the height of the material 7 in the material container 5 changes until the material container 5 is full. Then, the lower pusher device 2 is started to push away the material 7 in the material container 5 for overall packaging. Through the cooperation of the above-mentioned devices, the equipment realizes the cyclic and rapid packaging of the incoming materials, realizes the parallel mode of the pushing and stacking return action and the material 7 transportation action, effectively improves the efficiency of the pushing and stacking work, and the operation efficiency is increased by 30% compared with the serial pushing and stacking method, with high packaging efficiency.

[0060] As Figure 2 、 Figure 3 shown, the frame 1 includes a group of parallel rods 11 for fixing the feeding device 3. The upper surface of the parallel rod 11 at the end far from the lifting device 4 is fixed with the upper pusher device 6, and the lower surface of the parallel rod 11 is provided with support legs 18. The lower pusher device 2 is fixed in the space formed by multiple support legs 18.

[0061] The feeding device 3 is a device that transports the material 7 to the transportation track of the upper pusher device 6 to facilitate the upper pusher device 6 to push the material 7 into the material container 5. The feeding device 3 can have various structures as long as the above functions are achieved. Specifically, as Figure 2 、 Figure 3 shown, the feeding device 3 provided in this embodiment includes a driving shaft 15, a driven shaft 16 and a conveyor belt 9. One end of the parallel rod 11 is fixed with the driving shaft 15, and the other end of the parallel rod 11 is fixed with the driven shaft 16. The conveyor belt 9 is in a ring shape and is sleeved on the outer surfaces of the driving shaft 15 and the driven shaft 16. The driving shaft 15 is connected to a driving motor.

[0062] During use, the driving motor drives the driving shaft 15 to rotate, the driving shaft 15 drives the conveyor belt 9 to rotate, the conveyor belt 9 drives the driven shaft 16 to rotate, and the material 7 is placed on the conveyor belt 9. The material 7 is transported by the cyclic movement of the conveyor belt 9. Preferably, a material blocking and positioning device is provided at the end of the feeding device 3. Specifically, the material blocking and positioning device provided in this embodiment is a material blocking plate 8. The bottom parts of both ends of the material blocking plate 8 are respectively placed on the upper surface of the end of the parallel rod 11. When the material blocking plate 8 contacts the material 7, it prevents the material 7 from falling off due to the rotation of the conveyor belt 9.

[0063] The detection device 10 is a device that ensures the feeding device 3 transports the material 7 in place, facilitating the pushing of the material by the upward pusher device 6. The detection device 10 can have various structures as long as the above functions are achieved. Specifically, the detection device 10 provided in this embodiment is a diffuse reflection infrared sensor. The diffuse reflection infrared sensor utilizes the shading or reflection of the infrared beam by the detected material 7, and is gated by a synchronous circuit to detect the presence or absence of an object, converting the received infrared radiation into an electrical signal and applying it. The diffuse reflection infrared sensor can be of any model or specification, such as the NPN type with the model number E3Z-D61 sold on the market, or the PNP type with the model number E3Z-D81.

[0064] Preferably, the detection device 10 includes multiple groups, and the multiple groups of detection devices 10 are evenly distributed along the transportation direction of the feeding device 3 and the transportation direction of the upward pusher device 6. Through multi-angle detection in the horizontal and vertical directions, it avoids false detection caused by the offset of the material 7, has high detection accuracy, and is beneficial for the subsequent automatic regular stacking of the material 7.

[0065] After ensuring that the material 7 is transported in place, the upward pusher device 6 contacts the material 7 and moves towards the material container 5, pushing the material 7 on the conveyor belt 9 into the material container 5. Then, the upward pusher device 6 detaches from the material 7 and moves away from the material container 5 to avoid contacting the material 7 on the conveyor belt 9 that has not been transported in place. The upward pusher device 6 can be any structure that realizes the above operations. Specifically, as Figure 4 、 Figure 5 shown, the upward pusher device 6 provided in this embodiment includes an upward pusher plate 14. The upward pusher plate 14 is fixed on the sliding platform 17 through an azimuth adjustment device. The sliding platform 17 reciprocates above the feeding device 3 through an upper telescopic cylinder 13.

[0066] Specifically, as Figure 4 、 Figure 5 shown, the upward pusher plate 14 includes a vertical plate 19 and a horizontal plate 20. The vertical plate 19 and the horizontal plate 20 are arranged in an "L" shape. The azimuth adjustment device is a swing cylinder 12. The first end of the swing cylinder 12 is hinged to the upper surface of the horizontal plate 20, and the second end of the swing cylinder 12 is hinged to the upper surface of the sliding platform 17. The vertical height of the second end is greater than the vertical height of the first end.

[0067] As Figure 4 shown, when the swing cylinder 12 extends, the horizontal plate 20 is parallel to the sliding platform 17, and the end face of the vertical plate 19 is in full contact with the material 7. The upward pusher plate 14 is in the low position. At this time, the upper telescopic cylinder 13 extends, driving the sliding platform 17 to move towards the material container 5, pushing the material 7 into the material container 5.

[0068] As Figure 5As shown in the figure, when the swing cylinder 12 contracts, the horizontal plate 20 and the sliding platform 17 form an obtuse angle, the upper material pushing plate 14 is placed at a high position, and the lowest part of the upper material pushing plate 14 does not contact the material 7, which does not affect the conveying of the material 7 by the material receiving device 3. At this time, the upper telescopic cylinder 13 contracts, driving the sliding platform 17 to move away from the material container 5 to prepare for the next layer of material pushing. During the return process of the upper material pushing plate 14, the lower material receiving device 3 works normally to ensure that the two operations are carried out simultaneously, improving the working efficiency.

[0069] The material container 5 is a device for receiving materials 7 layer by layer, facilitating the stacking of materials 7 and being conducive to the packaging of materials 7. The material container 5 can be reasonably designed according to the actual required packaging size to meet different packaging size requirements. Specifically, as Figure 6 shown, the material container 5 provided in this embodiment includes a first plate 21, a second plate 22, a third plate 23, and a fourth plate 24 connected in sequence. The material container 5 is in the shape of a square frame, and the cross-section of the material container 5 in the direction consistent with the transportation trajectory of the upper material pushing device 6 is set in a "mouth" shape. The lower surface of the first plate 21 contacts the upper surface of the lifting device 4, the second plate 22 and the fourth plate 24 are respectively vertically placed at both ends of the first plate 21, and the first plate 21 is parallel to the third plate 23. When the materials 7 in the material container 5 are fully stacked, the lower material pushing device 2 is started, and the lower material pushing device 2 pushes the whole stack of materials 7 out as a whole.

[0070] The lower material pushing device 2 is any device that can achieve the above functions. Specifically, as Figure 6 shown, the lower material pushing device 2 provided in this embodiment includes a lower material pushing plate 27. The lower material pushing plate 27 is connected to the lower telescopic cylinder 25. The frame 1 includes a lower telescopic cylinder fixing frame 26. The lower telescopic cylinder fixing frame 26 is within the space formed by multiple support legs 18. The lower telescopic cylinder fixing frame 26 horizontally fixes the lower telescopic cylinder 25, and the lower material pushing plate 27 is vertically connected to the lower telescopic cylinder 25.

[0071] Preferably, an anti-clamping device 28 is provided on the lower material pushing plate 27. When the material 7 falls into the gap between the frame 1 and the upper edge of the lower material pushing plate 27, when the lower telescopic cylinder 25 drives the lower material pushing plate 27 to reciprocate, it is very easy to cause wear and deformation of the material 7. As Figure 7As shown in the figure, the lower pushing plate 27 provided in this embodiment includes a fixed plate 29 and a folding plate 32. The anti-pinching device 28 includes a connecting member 30 and a reset member 31. The connecting member 30 connects the fixed plate 29 and the folding plate 32. The folding plate 32 is placed above the fixed plate 29. The folding plate 32 rotates around the connecting member 30 as the axis. One end of the reset member 31 is placed at the end of the fixed plate 29, and the other end of the reset member 31 is placed at the end of the folding plate 32. The reset member 31 aligns the rotated folding plate 32 with the fixed plate 29. When the material 7 falls into the gap between the rack 1 and the upper edge of the lower pushing plate 27, the reset member 31 deforms to bend the folding plate 32, increasing the gap between the rack 1 and the upper edge of the folding plate 32, avoiding mechanical failures caused by material 7 jamming and also avoiding damage to the material 7. When the material 7 leaves the gap between the rack 1 and the upper edge of the lower pushing plate 27, the reset member 31 returns the rotated folding plate 32 to its original position and aligns it with the fixed plate 29.

[0072] Specifically, the connecting member 30 provided in this embodiment can be set as a hinge, and the reset member 31 can be set as a tension spring. The structure is simple and the production cost is low, which is suitable for popularization and application.

[0073] As Figure 8 shown in the figure, the present invention also provides an automatic boxing control method, which uses the above automatic boxing equipment and includes the following steps.

[0074] S1: Start the material receiving device 3. The material receiving device 3 transports the first layer of material 7 to below the upper pushing device 6, and the detection device 10 ensures that the first layer of material 7 is transported in place.

[0075] Specifically, taking the material 7 as cigarettes as an example, S1 further includes:

[0076] S11: Assume the total amount of packaging material 7 is Z, the number of materials 7 to be packaged is D, and the number of materials 7 already packaged is Y. Among them, Y = 0, and Z = D + Y.

[0077] S12: According to the size of the material container 5 and the size of the material 7, determine the number of materials 7 per layer N and the stacking layer number F. Among them, assume the length of the material container 5 is H, the length dimension of the material 7 is L, and the width dimension of the material 7 is W. Specifically, in this embodiment, the length H of the material container 5 is 490 mm, the length L of the cigarette is 280 mm, and the width W of the cigarette is 88 mm. The detection device 10 is arranged in the number of columns P in the transportation track direction of the material receiving device 3 ≥ ROUNG DOWN (H / W, 0), P ≥ N, and it is obtained that P = 5.

[0078] S13: According to the size of the material 7, determine the number M of the detection device 10 arranged in the transportation track direction of the upper pushing device 6 ≥ ROUNG UP (L / W, 0), and it is obtained that M = 4;

[0079] S14: Assume the number of layers pushed is C, and determine whether the material 7 is complete. Specifically, when D / N ≥ 1, at this time C = P, and P columns of the detection device 10 need to detect signals. At the same time, in each of the C columns, there are ≥ M - 1 detection devices 10 detecting the material 7.

[0080] S15: When D / N < 1, at this time C = D. If D columns of the detection device 10 detect signals, and at the same time, in each of the C columns, are there ≥ M - 1 detection devices 10 detecting the material 7? If so, the upward feeding device 6 operates. If not, report a material shape abnormal fault, stop the equipment, and perform maintenance; if more than D columns of the detection device 10 detect signals, then report a multi-material fault, stop the equipment, and perform maintenance.

[0081] S2: The upward feeding device 6 moves towards the material container 5. At the same time, the lifting device 4 drives the material container 5 to rise. The upward feeding device 6 contacts the first layer of material 7 and pushes the first layer of material 7 into the material container 5. At this time, it is necessary to detect whether the feeding is in place. If it is in place, the upward feeding device 6 returns to its original position. If not, report a stacking fault, stop the equipment, and perform maintenance.

[0082] S3: The upward feeding device 6 moves away from the material container 5. At the same time, the material receiving device 3 transports the second layer of material 7 to below the upward feeding device 6. The upward feeding device 6 does not contact the second layer of material 7, and the lifting device 4 drives the material container 5 to lower to receive the second layer of material 7.

[0083] S4: Repeat the above S1 to S3 until the lifting device 4 drops to the low position. At this time, the material container 5 is full.

[0084] Specifically, S4 also includes

[0085] S41: When the Y value increases by M, the D value decreases by M, and the F value subtracts 1, start the material receiving device 3, and the upward feeding device 6 moves away from the material container 5.

[0086] S42: Determine the D value. When D > 0, determine whether F > 0. When F > 0, the lifting device 4 descends one layer.

[0087] S43: When D > 0 and at the same time F ≤ 0, the lifting device 4 descends to the low position, and the downward feeding device 2 starts.

[0088] S44: When D ≤ 0, each device stops working.

[0089] S5: Start the downward feeding device 2, and the downward feeding device 2 moves towards the material container 5 to push away the material 7 in the material container 5.

[0090] The working principle of the present invention is:

[0091] Start the material receiving device 3. The driving motor drives the rotation of the main shaft 15. The main shaft 15 drives the rotation of the conveyor belt 9. The conveyor belt 9 drives the rotation of the driven shaft 16. The material 7 is placed on the conveyor belt 9. The cyclic movement of the conveyor belt 9 drives the transportation of the material 7. When the foremost material 7 contacts the baffle 8, each detection device 10 detects simultaneously to ensure that the material 7 is transported in place.

[0092] After the material 7 is transported in place, the driving motor stops. The swing cylinder 12 of the upper material pushing device 6 extends, lowering the upper material pushing plate 14 to the low position. After the upper material pushing plate 14 reaches the low position, the upper telescopic cylinder 13 extends, pushing the material 7 into the material container 5. After that, the lifting device 4 descends to the set height.

[0093] After the material receiving device 3 is started, it continues to receive the material 7. The swing cylinder 12 of the upper material pushing device 6 contracts, lifting the upper material pushing plate 14 to the high position. After the upper material pushing plate 14 reaches the high position, the upper telescopic cylinder 13 contracts, pushing the sliding platform 17 of the upper material pushing device 6 back to its original position. After returning to the original position, if the detection device 10 detects that the material 7 is in place, the above actions are repeated.

[0094] When the material container 5 is full, start the lower material pushing device 2. The lower telescopic cylinder 25 extends, driving the lower material pushing plate 27 to push the already full material 7 into the designated container, thus completing the stacking and packaging work for this time. Repeating the above operations realizes the cyclic work of the packaging link.

[0095] The advantages and positive effects of the present invention are:

[0096] 1. The structure of the present invention is simple and the operation is convenient. The material is transported through the material receiving device, and the detection device ensures that the material is transported in place. The material of this layer is pushed into the material container through the upper material pushing device. The upper material pushing device rises and returns to its original position. At the same time, the material receiving device starts to transport the next batch of materials. During the above process, the lifting device descends layer by layer as the height of the material layer in the material container changes until the material container is full. Then start the lower material pushing device to push away the material in the material container for overall packaging. Through the cooperation of the above devices, the equipment realizes the cyclic and rapid packaging of the incoming materials, realizes the parallel mode of the stacking and returning actions and the material transportation actions, effectively improves the efficiency of the stacking work, and the operation efficiency is increased by 30% compared with the serial stacking method, and the packaging efficiency is high.

[0097] 2. The material receiving device of the present invention drives the rotation of the main shaft through the driving motor, the main shaft drives the rotation of the conveyor belt, the conveyor belt drives the rotation of the driven shaft, the material is placed on the conveyor belt, and the cyclic movement of the conveyor belt drives the transportation of the material. A baffle positioning device is provided at the end of the material receiving device to prevent the material from falling off. The structure of the material receiving device is simple and the production cost is low, which is suitable for popularization and application.

[0098] 3. The present invention detects whether the material is transported to the transportation track of the upward pusher device through a diffuse reflection infrared sensor. The diffuse reflection infrared sensors are respectively arranged in the transportation direction of the material receiving device and the transportation direction of the upward pusher device, avoiding false detection caused by material deviation, having high detection accuracy, being beneficial to the subsequent automatic regular stacking of the material, having a simple structure, low manufacturing cost, and high cost performance.

[0099] 4. In the upward pusher device of the present invention, the upward pusher plate is connected by a swing cylinder. The swing cylinder is installed at an angle with the sliding platform. When the swing cylinder extends, the upward pusher plate descends to contact the material for pushing operation. When the swing cylinder contracts, the upward pusher plate rises above the material and returns to the initial state to prepare for the next pushing operation. During the return process of the upward pusher plate, the lower material receiving device works normally to ensure that the two operate simultaneously, improving the working efficiency.

[0100] 5. The present invention installs an anti-clamping device on the downward pusher device. When the material falls into the gap between the frame and the upper edge of the folding plate, when the lower telescopic cylinder drives the fixed plate to reciprocate, the reset part deforms to bend the folding plate, increasing the gap between the frame and the upper edge of the folding plate, avoiding mechanical failures caused by material jamming and at the same time avoiding material damage. The connecting part can be set as a hinge, and the reset part can be set as a tension spring, having a simple structure, low production cost, and being suitable for popularization and application.

[0101] 6. The equipment in the present invention can be flexibly customized according to the size of the upstream production line, with convenient docking, simple process, wide application range, and high promotion value.

[0102] The above has described a specific embodiment of the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
