Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tobacco storage equipment, and particularly relates to a high-efficiency conveying and storing device for tobacco logistics. BACKGROUND

[0002] Tobacco logistics refers to packaging and storing of completed cigarettes. The existing tobacco is packaged and stored after production. Tail goods (i.e., a storage rack cannot be stored full) appear when each batch of goods is stored. Tail boxes also exist in the tail goods. The existing storage method for such goods is to store the tail boxes on a separate storage rack. This results in multiple storage racks that are not stored full, which wastes a large amount of storage space.

[0003] Tail boxes (i.e., packaging boxes that are not completely filled with goods) also exist in the tail goods. If the tail boxes are mixed with full boxes during storage, the tail boxes cannot be distinguished during goods taking, which results in actual goods quantity not matching required goods quantity. The existing processing method for this problem is to separately store the tail boxes and periodically split and repackage the tail boxes. This operation can effectively avoid mixing of full boxes and tail boxes, but requires time and labor during reorganization. The separately stored tail boxes also occupy a large amount of storage space, which also reduces conveying and storage efficiency. SUMMARY

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0037] Example 1

[0038] like Figures 1-7 As shown, a high-efficiency handling and storage device for tobacco logistics includes a storage rack 1, with a storage layer 2 on the upper part and a sorting layer 3 on the lower part. A feeding device is installed at the front end of the storage rack 1. The feeding device is used to classify the transported materials, and the materials in whole boxes are sent to the storage layer 2 for storage, while the materials that are not in whole boxes are sent to the sorting layer 3 for temporary storage and processing.

[0039] A sliding guide rail 4 is installed at the bottom of the storage layer 2, and a transfer trolley 5 is installed on the sliding guide rail 4. The transfer trolley 5 is used to transport and stack the materials transferred from the feeding equipment. Similarly, when materials need to be retrieved, the stored materials can be transferred to the feeding equipment by the transfer trolley 5 and then transferred to the external equipment.

[0040] A material handling platform 6 is fixedly installed in the middle of the material handling layer 3. A temporary storage area 7 is provided on the upper surface of the material handling platform 6. A mechanical gripper 8 is provided on one side of the temporary storage area 7. The mechanical gripper 8 is a mechanical arm. A suction cup for gripping materials is installed at the front end of the mechanical arm. The materials in the packaging box are taken out by the suction cup and placed in the temporary storage area 7. An opening component for opening the packaging box is provided on the side of the material handling platform 6 facing the feeding equipment, and a sealing component for sealing the box is provided on the other side.

[0041] The feeding equipment includes a positioning frame 9, one end of which is connected to the storage rack 1, and the bottom of the other end is provided with a feeding port 10. After the material is transported to the positioning frame 9 by AGV or other handling equipment, it enters through the feeding port 10 and is then transported by a lifting platform for classification. An image acquisition device 11 is installed above the feeding port 10. The image acquisition device 11 uses a camera to identify the tail boxes. The tail boxes are materials that are not full. Labels are affixed to the upper surface of the box to distinguish them, which is convenient for image acquisition and identification. Full boxes are standard boxes. Inside the positioning frame 9, a lifting platform is installed that moves longitudinally back and forth along the height direction of the positioning frame 9. The upper surface of the lifting platform is equipped with a conveying roller group for conveying materials.

[0042] There are multiple storage layers 2, all of which are evenly distributed along the height of the storage rack 1. All storage layers 2 are used to store whole boxes of materials.

[0043] The transfer trolley 5 comprises a base 12, two walking wheels 13 are installed on both sides of the base 12, a motor for driving the walking wheels 13 to rotate is installed on the lower surface of the base 12, a radar is installed on the rear end face of the base 12, which is used to identify the distance between the transfer trolley 5 and the already stacked materials during the travel of the transfer trolley 5, a lifting plate 14 is installed on the upper surface of the base 12, which is lifted upward during the conveying of materials to avoid friction between the bottom of the materials and the upper surface of the sliding guide rail 4, and the lifting plate 14 falls after the transfer trolley 5 moves to the parking position, and the materials are parked above the sliding guide rail 4.

[0044] The opening box assembly comprises a moving platform 15 slidingly installed at the bottom of the sorting layer 3, and the installation method of the moving platform 15 is the same as that of the transfer trolley 5, and the main function is to convey the materials into the sorting layer 3. The upper part of the sorting area is provided with a longitudinal opening box device for opening the gland at the two side positions of the top of the packaging box along the moving direction of the moving platform 15, and the end of the longitudinal opening box device is provided with a transverse opening box device for opening the gland at the two end positions of the bottom of the packaging box.

[0045] The longitudinal opening box device comprises two symmetrically distributed guide wings 16, the front ends of the two guide wings 16 are closed and provided with cutting blades 17. In order to better cut the tape, the shape of the cutting blade 17 is changed from a vertical blade to a inverted T-shaped blade, which is convenient for cutting the middle seam and the two side positions of the tape. The cutting blade 17 can cut the tape on the upper surface of the packaging box. The distance between the two guide wings 16 gradually increases from the cutting blade 17 outward. The two guide wings 16 are in an eight-shaped distribution. The last end of the guide wing 16 extends to the outside of the packaging box and the lowermost end is lower than the height of the cover plate. During the conveying process, the cover plate at the two side positions of the packaging box is opened and pressed down. The lower side of the guide wing 16 is provided with a positioning guide plate which is in contact with the two side walls of the packaging box. During the travel, the packaging box is positioned to ensure that the axes of the packaging box, the guide wing 16 and the two positioning guide plates are parallel to each other during conveying, so as to avoid the inclination of the packaging box during conveying.

[0046] The transverse opening device comprises a vertically installed driving cylinder 18, a horizontal cross brace 19 is installed at the movable end of the driving cylinder 18, a threaded rod 20 is installed in the cross brace 19, a driving motor 21 is arranged at one end of the threaded rod 20, forward threads and reverse threads are arranged on the outer surface of the threaded rod 20, the forward threads and the reverse threads are symmetrically distributed about the center line of the threaded rod 20, two symmetrically distributed L-shaped opening and closing plates 22 are installed at the middle part of the threaded rod 20, the driving motor 21 is a forward and reverse motor, the two L-shaped opening and closing plates 22 are threadedly connected with the forward threads and the reverse threads respectively, and the driving motor 21 can drive the threaded rod 20 to rotate and then drive the L-shaped opening and closing plates 22 to move in opposite directions. When the transverse opening operation is performed, the driving cylinder 18 is lowered, at this time, the two L-shaped opening and closing plates 22 are located at the middle part of the threaded rod 20, with the falling of the driving cylinder 18, the two L-shaped opening and closing plates 22 fall into the box from the gap between the two end covers of the packaging box, then the driving motor 21 starts to work, the two L-shaped opening and closing plates 22 move to the two sides, at this time, the driving cylinder 18 moves upward, and in this process, the two L-shaped opening and closing plates 22 continuously move to the two sides, at this time, the end covers of the packaging box are turned outward, and when the two L-shaped opening and closing plates 22 reach the edge of the threaded rod 20, the movable end of the driving cylinder 18 moves downward again to apply an outward turning force to the two covers to prevent the covers from turning inward in the box.

[0047] The sealing assembly comprises a rack 23, a sealing device 24 is installed at the front end of the rack 23, a lifting platform 25 is installed at the rear end of the rack 23, a conveying belt is installed at the top of the lifting platform 25, an avoidance slot corresponding to the position of the conveying belt is arranged at the end of the storage layer 2, the packaging box is conveyed to the lifting platform 25 after being sealed by the sealing device 24, and the lifting platform 25 is lifted from the avoidance slot to the storage layer 2 to move the materials to the storage layer 2 for simultaneous storage with the existing whole-box goods.

[0048] The sealing device 24 comprises a conveying roller 26, a support frame 27 is installed above the conveying roller 26, a cover pressing device is installed at the front side of the support frame 27, a sealing machine 28 is installed at the rear side of the support frame 27, a transfer belt 29 is installed at the middle part of the support frame 27 and located at both sides of the packaging box, the transfer belt 29 provides a forward conveying power for the packaging box, the friction between the transfer belt 29 and the side wall of the packaging box can be used to stabilize the packaging box, the conveying roller 26 can reduce the friction at the bottom of the packaging box to avoid the phenomenon of backward tilting of the packaging box during forward movement, and the cover pressing device can press down the four covers at the top of the packaging box during forward movement of the packaging box to facilitate sealing of the sealing machine 28.

[0049] The capping device comprises a horizontally mounted support plate 30, the upper surface of the support plate 30 is provided with a jacking cylinder 31, the movable end of the jacking cylinder 31 is hingedly connected with a downward pressing bracket 32, the lower surface of the support plate 30 is vertically provided with a downward pressing plate 33, the front end of the downward pressing plate 33 is provided with an arc-shaped guide part, as the package box advances, the movable end of the jacking cylinder 31 pushes outward, the downward pressing bracket 32 overturns downward, the capping of one end of the package box is pressed downward, and the capping of the other end of the package box is turned inward under the action of the downward pressing plate 33, the downward pressing operation of the capping of both ends of the package box is completed through the downward pressing bracket 32 and the downward pressing plate 33, the two sides of the downward pressing plate 33 are provided with guide pressing plates 34 for pressing the capping of both sides of the package box, the guide pressing plates 34 press the capping of both sides of the package box inward and downward after covering the capping of both ends, and then the package box is sealed at the sealing machine 28.

[0050] The guide pressing plates 34 gradually increase in height from the downward pressing bracket 32 to the downward pressing plate 33, the spacing between the two guide pressing plates 34 gradually decreases, and the two guide pressing plates 34 are in an inverted eight-shaped distribution, the front end is large in opening to guide the capping of both sides, and the capping is prevented from being folded outward during the pressing process.

[0051] The working principle is that after the material is transferred to the feeding port 10 of the positioning frame 9 by the AGV trolley, the image acquisition device 11 is used for identification, if there is no tail box identification, the material is transferred to the storage layer 2 by the material table for storage, if the tail box is identified, the material table is used for conveying to the material sorting layer 3 for integrated processing, first, the tail box is transferred from the material table to the moving platform 15, the tail box is moved by using the moving platform 15, first passes through the box opening assembly during the moving process, the box opening assembly is used for opening the box of the tail box, four cappings on the upper surface of the tail box are opened and then stopped in front of the material sorting table 6, the material in the tail box is grabbed by the mechanical gripper 8 and placed in the temporary storage area 7, after the material grabbing is completed, the empty box is retreated to the feeding device by using the moving platform 15, and finally transferred to the AGV moving trolley for transportation, after the temporary storage area 7 stores the material meeting the whole box packaging, the empty box is placed at the front end of the sealing assembly, the material sorting table 6 and the sealing device are provided with a transfer conveyor belt between them, which is used for conveying the package box to the entrance of the sealing device for sealing operation, the material in the temporary storage area 7 is placed in the empty box by the mechanical gripper 8, after the empty box is filled, the empty box is sealed by the sealing assembly and then transferred to the storage layer 2 by the lifting table 25 for storage.

[0052] Embodiment 2

[0053] The same as embodiment 1 is not described, and the difference is that Figures 8-9As shown, in actual operation, when opening a large number of cargo boxes, only the top layer of cargo is empty. In this case, the design of the horizontal opening device cannot effectively lower the L-shaped opening plate 22, making it impossible to use the original horizontal opening device to open the lids at both ends of the box. To address this, we improved the opening assembly and the mechanical gripper 8. First, the original horizontal opening device was removed. The two original guide vanes 16 were installed on the upper surface of the positioning guide plate. Cutting blades 17 are still installed at the front ends of the two guide vanes 16. A crossbar 36 is installed between the two guide vanes 16. An air nozzle 36 is installed on the front end of the crossbar 36. The air nozzle 36 is flat and installed at an angle of 45-60 degrees to the upper surface of the box. As the box passes by, the upper surface of the box is blown up, directing the opening towards... The air nozzle 36 blows upwards onto the cover. Multiple crossbars 36 are concentrated in the middle of the two guide vanes 16, with the rearmost nozzle 36 forming a larger angle with the packaging box, causing its end to tilt upwards. Brush rollers 37 are installed at the ends of the two guide vanes 16. As the packaging box passes, the brush rollers 37 block the tilted cover, ultimately opening it to facilitate the rear robotic arm's grabbing of the goods. Since only one end of the cover is open, the suction force of the suction cups on the robotic arm needs to be adjusted, increasing the suction by 20-30% to enhance the material's adhesion, ensuring that the material does not fall due to the unopened cover when the packaging box is removed. Removing the item will also lift the unopened cover upwards. This structure is also applicable to other sizes of tail boxes, and compared to the transverse opening device of Example 1, the structure is simpler and easier to install and operate.

[0054] Example 3

[0055] The similarities with Example 1 will not be repeated here; the differences are as follows: Figure 10 As shown, to facilitate the reorganization of leftover boxes into full boxes for storage and shipment, based on Example 1, we improved the sorting table 6 by designing it to be recessed from the original upper surface of the guide rail. The temporary storage area 7 is recessed below the guide rail so as not to affect the passage of the moving platform 15. The mechanical gripper 8 is installed on the upper surface of the guide rail. After the leftover box passes the box opening component, it can be placed at the inlet of the box sealing device for retention. When the second leftover box enters and passes the box opening component, it stops above the temporary storage area 7. The mechanical gripper 8 directly grabs the material in the second leftover box and transfers it to the first leftover box. After the first leftover box is full, it is pushed into the box sealing component for sealing and then transferred to the storage layer 2. This cycle repeats. Compared with Example 1, this method can improve the utilization rate of packaging boxes. There is no need to provide packaging boxes separately. The leftover boxes can be sorted by circulating them to form full boxes for transportation.

[0056] Embodiment 4

[0057] The same as embodiment 1, the difference is that as shown, the end of the lifting platform and the transfer trolley in the storage layer are cancelled, and in this embodiment, the material package in the sorting table does not need to be transferred to the storage layer by the end lifting platform after completion, but is transferred to the lifting platform by the moving platform, and then the goods are transported to the storage layer by the moving platform, the upper part of the unloading assembly and the wind direction assembly of the sorting layer is provided with an installation plate which can adjust the height, for adjusting the height of the unloading assembly and the sealing assembly, avoiding affecting the passing of the box after packaging, the positioning plate 38 is installed on both sides of the bottom of the storage layer, the inner side of the positioning plate is provided with a support frame 39, the support frame is a rectangular frame, and the outer side walls of the two long sides are hinged to the inner side of the positioning plate, so that the end of the support frame can be adjusted in a small amplitude to change the inclination angle of the support frame, the iron sheet 40 is installed at the middle position of the front end of the support frame, the electromagnet 41 is installed at the front end of the lifting platform, the electromagnet uses the square electromagnetic chuck produced by Dongguan Deang Electromagnetic Technology Co., Ltd., the end of the support frame is controlled to be lifted or sunk by the cooperation of the electromagnet and the iron sheet, so as to change the inclination angle of the support frame, finally to achieve the purpose of taking goods and storing goods, the lifting platform needs to be improved here, the improved lifting platform includes a lifting bottom plate 42, a placing plate 43 is installed above the lifting bottom plate, a gravity sensor 44 is installed in the middle of the placing plate, a guide column 45 is arranged between the end of the placing plate facing the support frame and the lifting bottom plate, a telescopic spring 46 is arranged outside the guide column between the placing plate and the lifting bottom plate, the electromagnet is located at the end of the placing plate facing the support frame, when the material needs to be placed, the lifting bottom plate rises to the storage layer, at this time the placing plate is flush with the support frame, the electromagnet is electrified and magnetically attracted with the iron sheet, then the lifting bottom plate continues to rise by 5-10 cm, at this time the end of the placing plate lifts the end of the support frame, the placing plate and the support frame form a slope with high front end and low rear end, at this time the inclination angle of the support frame is 3-4 degrees, the material slides from the placing plate to the support frame and slides along the upper surface of the support frame to the end, completing the storage work;

[0058] Similarly, when the material needs to be taken out, the lifting bottom plate rises to the storage layer, and after the electromagnet is powered on and the iron sheet generates an attractive force when the storage plate and the support frame are flush, the lifting plate falls by 5-10 cm, synchronously driving the front end of the support frame to move downward, at this time the support frame and the storage table form a slope with the front end low and the rear end high, the material will slide along the surface of the support frame from the end to the storage table. In order to avoid multiple materials from sliding at the same time, a tension spring 47 is installed below the front end of the support frame. When the material is taken out, the front end of the support frame moves downward and applies downward pressure to the tension spring. When the material slides to the storage plate and contacts the pressure sensor, the electromagnet is de-energized. At this time, the electromagnet is separated from the iron sheet, and the support frame loses the downward traction and is reset upward under the action of the tension spring. At the same time, the tension spring also supports the front end of the support frame in the static state, keeping the front end of the support frame slightly higher than the end, preventing the material from sliding forward during storage. Similarly, in order to avoid the material from sliding forward too fast when taking out the material, reverse sliding dampers need to be installed on both long sides of the support frame. First, we installed conveying rollers inside the support frame, and one-way ratchet clutches were installed at both ends of the conveying rollers. When the material is stored, the conveying rollers rotate in the forward direction and will not generate resistance to the transportation of the material. When the material is taken out, the reverse rotation of the conveying rollers will be damped by the one-way ratchet clutches, so that the material will be subjected to resistance when the conveying rollers are reversed during the taking-out process, thereby reducing the sliding speed of the material. Through this way, the material is transferred. Compared with the existing warehouse transfer equipment, the material transfer can be realized without the addition of other equipment, reducing the equipment investment during logistics and warehousing.

[0059] But in the actual application process, the installation of the conveying roller in the above-mentioned device increases the weight of the support frame, causes the traction force received by the support frame to increase when the support frame is tilted upward or downward, and also causes the support frame to be difficult to reset after rotation in the full load case, therefore we modify the conveying roller, remove the conveying roller, and change the installation of the rotating wheel 48 on the upper surface of the two long edges of the support frame, the outer side wall of the rotating wheel is provided with a positive protrusion towards the end of the support frame, the inside of the rotating wheel is connected with the support frame through a sealed bearing, so that the rotating wheel rotates forward when storing materials in the storage layer, the materials slide to the end when the support frame is tilted, the positive protrusion 49 does not hinder the sliding of the materials, and also provides a weak thrust to the materials, and when the materials need to be taken, the end of the positive protrusion will rub and collide with the lower edge of the materials, thereby driving the rotating wheel to rotate in reverse, generating resistance to the sliding of the materials, so as to slow down the sliding speed of the materials, in order to further slow down the sliding resistance of the materials, we also inject lubricating grease into the sealed bearing, compared with conventional lubricating oil, the internal friction resistance of the lubricating grease is larger, and the cooperation with the positive protrusion can maximize the resistance effect when the materials slide, thereby achieving the effect of slowing down the sliding speed of the materials, it should be noted that in the actual use process, the rotating wheel has two types, one has a positive protrusion on the outer side wall, and the other is a common rotating wheel, the two types of rotating wheels are arranged alternately, and can play a spacing role between the materials, so that a gap is generated between the first material and the second material when the materials slide forward, so that two adjacent materials do not fall on the material plate at the same time, compared with the conveying roller, the mass is smaller, the mass of the entire support frame is reduced, the rotation of the support frame when storing and taking materials is more convenient, the angle adjustment and reset of the support frame are not affected, and finally the purpose of moving the materials without the participation of the power device when storing and taking the materials in the storage layer is achieved, the structure of the entire device is simpler, more storage space is not occupied, and the materials can be stored and taken efficiently.

[0060] Finally, it should be noted that: the above only describes the preferred embodiments of the present application and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
