Description

Technical Field

[0001] The invention relates to the technical field of cigarette packet conveying equipment, in particular to an automatic cigarette packet conveying and collecting device. Background Art

[0002] Cigarette pack transportation refers to the process of stacking cigarette packs in a certain manner and standard in the cigarette manufacturing and logistics process for efficient transportation and storage. The process first selects appropriate standard pallets, and then adopts stacking methods such as layering and cross stacking according to the specifications and shapes of the cigarette packs to optimize space utilization and ensure stacking stability. Height control is the key. Too high may reduce stability and cause damage to the goods. After stacking, use strapping tape or wrapping film to reinforce the cigarette packs to ensure stability during transportation. During loading, the position of the pallet is reasonably arranged to ensure a stable center of gravity and reduce shaking and collisions during transportation. Through these detailed link coordination and planning, cigarette pack palletizing transportation can improve the efficiency and safety of the entire logistics process.

[0003] A Chinese patent discloses a cigarette pack cage car palletizing device and a palletizing method thereof (authorization announcement number CN118359011B), which includes a first bidirectional conveyor, a second bidirectional conveyor for docking with a second conveyor to output cigarette packs, a third conveyor for outputting cigarette packs from the first bidirectional conveyor to the second bidirectional conveyor, a flipping transmission device provided at the output position of the first bidirectional conveyor and the second bidirectional conveyor, a stacking station for collecting and outputting cigarette packs output by the flipping transmission device, a cage car for collecting cigarette packs, and a third conveyor for outputting cigarette packs from the stacking station. The transfer device is transferred to the cage car, in which the cigarette packs with empty cigarette strips on the bottom are cushioned by air column bags, making the bottom surface of the cigarette packs more flat and less likely to tilt, and the stacked cigarette packs are also less likely to collapse. This solves the technical problem that some special-shaped cigarette strips are placed on one side of the cigarette pack, which is easy to tilt to one side during later transportation and palletizing, resulting in uneven stacked cigarette packs. However, the patent is insufficient in the monitoring function of later palletizing, which may result in problems that cannot be handled and adjusted in time after palletizing is completed, making it difficult to ensure the integrity of cigarette pack transportation.

[0004] In addition, since the sizes of special-shaped cigarettes themselves are different, the shapes and sizes of packaged cigarette packs are also different. The contact areas of the upper and lower layers of cigarette packs are large and small, and the force is uneven. The heights of the cigarette packs on the left and right sides are different, and the cigarette packs cannot be stacked flat on the pallet, resulting in damage to cigarettes during transportation. In addition, since the metal buckle connection position of the existing elastic band is fixed, but the height of the cigarette stack is different, it is easy to be tied too tightly or too loosely. Too tight bundling may compress the cigarettes, and too loose bundling cannot fix the cigarettes well. For this reason, an automatic cigarette pack conveying and collection device is proposed.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figures 1 to 9 In an embodiment of the present invention, an automatic cigarette pack conveying and collecting device comprises a plurality of frame components 1, wherein the frame component 1 comprises an outer frame 101, wherein a one-way air intake pipe 102 is fixedly connected to the front side wall of the outer frame 101, wherein a spring-type ejector one-way valve is installed inside the one-way air intake pipe 102, wherein the one-way valve can be opened by pushing the ejector with a tool, wherein the principle is similar to that of an air intake nozzle of a wheel, wherein a mouth-shaped air delivery passage 103 connected to the one-way air intake pipe 102 is opened inside the outer frame 101, wherein an inner frame 104 is fixedly connected to the inner side wall of the outer frame 101 through a plurality of air intake fixed pipes 105, wherein the inner frame 104 is a hollow structure, wherein a plurality of grooves for placing cigarette packs are arranged on the upper side wall of the inner frame 104, wherein a clamping and fixing component 2 for clamping and fixing cigarette packs is fixedly connected inside each groove of the inner frame 104, wherein stacking and plugging components 3 for stacking and fixing are installed at the four corners of the outer frame 101, wherein a monitoring component 4 for monitoring gas leakage is threadedly connected to the air intake fixed pipe 105;

[0041] When an inert gas is introduced into the one-way air inlet pipe 102, the gas can enter the inner frame 104 through the air delivery channel 103 and the air inlet fixing pipe 105, thereby driving the multiple clamping and fixing components 2 inside the inner frame 104. The inert gas can be nitrogen. The inert gas can effectively reduce the thermal expansion and contraction caused by the temperature difference of the ambient temperature, thereby improving the stability of the device.

[0042] The clamping and fixing assembly 2 includes two support tubes 201 connected and fixed to the inner walls on both sides of the groove in the inner frame 104. Two pistons 202 are slidably connected to the left and right sides of the middle of the two support tubes 201. Both ends of the support tubes 201 are rotatably connected to the rotating tube 203 by means of mechanical seals. The side walls of the two pistons 202 that are away from each other are fixedly connected to square rods 204. The rotating tube 203 is drilled with a 90-degree thread groove 205. When the guide rod 206 moves from the starting point of the thread groove 205 to the end point, the rotating tube 203 can be electrically rotated 90 degrees in total. A guide rod 206 fixedly connected to the square rod 204 is slidably connected by a snap-fit ​​manner, and a ball is rollingly connected to the top of the guide rod 206, so as to reduce the resistance when the guide rod 206 moves. The ends of the two rotating tubes 203 that are away from each other are fixedly connected to a transmission rod 207, and the lower ends of the two transmission rods 207 are rotatably connected to the left and right side walls of the clamping plate 208. Two limit plates 209 are fixedly connected to the inner wall of the support tube 201, and the square rod 204 passes through the limit plate 209. The limit plate 209 is used to limit the square rod 204 to prevent the square rod 204 from rotating.

[0043] The gas enters the support tube 201 through the inner frame 104, driving the two pistons 202 to separate, and at the same time, the piston 202 pushes the thread groove 205 of the rotating tube 203 through the square rod 204 and the guide rod 206, causing the thread groove 205 to rotate. The thread groove 205 drives the clamping plate 208 to flip upward through the transmission rod 207. When the clamping plate 208 flips upward, the cigarette pack can be clamped.

[0044] The clamping and fixing assembly 2 also includes a sliding box 210 that is slidably connected to the inner walls of the front and rear sides of the groove in the inner frame 104. The lower side walls of the two transmission rods 207 are fixedly connected to multiple racks 211 that are relatively staggered. The inner walls of the upper and lower sides of the sliding box 210 are rotatably connected to multiple gears 212 that mesh with the racks 211. The positions of the multiple racks 211 and the gears 212 are distributed as shown in FIG. Figure 4 shown.

[0045] Since the multiple racks 211 fixedly connected to the lower side walls of the two clamping plates 208 are all slidably connected to the inside of the sliding box 210 and are all engaged with the gear 212, when one of the clamping plates 208 is flipped upward, it will drive the other clamping plate 208 to rotate together through the rack 211, and finally realize the synchronous rotation of the two clamping plates 208, and the two clamping plates 208 can be in a horizontal state when rotating to hold up the cigarette pack. For longer cigarette packs, the two transmission rods 207 can clamp the cigarette packs when flipping upwards. For taller cigarette packs, the two transmission rods 207 can lift the cigarette packs so that they are against the lower side wall of the upper inner frame 104 to achieve clamping and fixation.

[0046] The stacking plug assembly 3 includes a mounting hole 301 drilled in one corner of the outer frame 101, and the mounting hole 301 is connected to the inside of the one-way air inlet pipe 102. The upper side wall of the outer frame 101 is fixedly connected to an insert tube 302 whose inner diameter is smaller than the mounting hole 301. The mounting hole 301 can be set to a cone, with the small diameter facing upward, so that the inner diameter of the insert tube 302 is smaller than the mounting hole 301, and the insert tube 302 is connected to the mounting hole 301. In addition, a sealing ring is fixedly connected to the top of the insert tube 302, which is not shown in the figure. The mounting hole 301 and the insert tube 302 are connected. 02 inner wall is fixedly connected with sealing ring plate 303 and spring plate 304, between spring plate 304 and sealing ring plate 303 is arranged top plate 305 that fits with sealing ring plate 303, between top plate 305 and spring plate 304 is fixedly connected with thrust spring 306, the sealing ring plate 303, spring plate 304, top plate 305 and thrust spring 306 in mounting hole 301 and insert cylinder 302 are symmetrically arranged, the specific symmetry of sealing ring plate 303, spring plate 304, top plate 305 and thrust spring 306 is as follows: Figure 8 As shown, a vertically arranged top rod 307 is fixedly connected to the lower side wall of the sealing ring plate 303 located inside the mounting hole 301 .

[0047] When the outer frame 101 is stacked, the insert tube 302 is inserted into the mounting hole 301, so that the push rod 307 pushes the two top plates 305 to separate from each other, so that the two top plates 305 are not in contact with the sealing ring plate 303. At this time, the top end of the insert tube 302 is in contact with the sealing ring plate 303, thereby achieving sealing between the insert tube 302 and the mounting hole 301.

[0048] The side wall of the insert cylinder 302 is connected and fixedly connected to a vent cylinder 308, a movable plug 309 is slidably connected inside the vent cylinder 308, a limiting rod 310 penetrating the vent cylinder 308 is fixedly connected to the side wall of the movable plug 309, a thin tube is fixedly connected to the movable plug 309 penetrating a side wall of the vent cylinder 308, the thin tube of the vent cylinder 308 can play a more stable limiting role for the limiting rod 310, a socket 311 matching the limiting rod 310 is bored on the outer frame 101, and whether the limiting rod 310 is inserted into the socket 311 can be directly observed to determine whether the outer frame 101 is neatly stacked.

[0049] When the insert 302 is fully inserted into the mounting hole 301, the interiors of the multiple outer frames 101 and the inner frame 104 are all connected. When the air pressure filled into the outer frame 101 is relatively high, the clamping and fixing assembly 2 can clamp and fix the cigarette pack. In addition, the air pressure can also push the movable plug 309 to move, so that the movable plug 309 drives the limiting rod 310 to be inserted into the socket 311. At this time, the connection between the two outer frames 101 is realized. At this time, the staff can judge whether the two outer frames 101 are connected in place by observing the socket 311.

[0050] Example 2: Please refer to Fig.10Based on Example 1, the monitoring component 4 includes a monitoring tube 401 threadedly connected to the air intake fixed pipe 105, a magnetic plug 402 and a circular plate 403 are slidably connected inside the monitoring tube 401, a connecting spring 404 is fixedly connected between the magnetic plug 402 and the opposite side walls of the circular plate 403, two ventilation plug tubes 406 that penetrate the monitoring tube 401 are inserted on the circular plate 403, and the circular plate 403 is connected to the outside air through the ventilation plug tubes 406. A threaded rod 405 threadedly connected to the monitoring tube 401 is rotatably connected to the circular plate 403, and a handle is fixedly connected to the end of the threaded rod 405 away from the circular plate 403 to facilitate the staff to rotate and adjust.

[0051] The monitoring component 4 also includes a fixing frame 407 fixedly connected to the two ventilation jack tubes 406 through two connecting rods, the upper side wall of the fixing frame 407 is fixedly connected to the sound and light alarm 408, the lower side wall of the fixing frame 407 is fixedly connected to the magnetic switch 409 electrically connected to the sound and light alarm 408, and a magnetic block is embedded in the magnetic plug 402. When the magnetic plug 402 is close to the magnetic switch 409, the magnetic switch 409 energizes the sound and light alarm 408. In addition, when the connecting spring 404 is not under force, the magnetic plug 402 and the magnetic switch 409 are in the same vertical plane, that is, the magnetic plug 402 can be sensed by the magnetic switch 409.

[0052] After the gas is added, the staff installs the monitoring component 4 on the air intake fixed pipe 105 with a thread, and then rotates the threaded rod 405, so that the circular plate 403 can push the magnetic plug 402 through the connecting spring 404, so that part of the gas inside the monitoring tube 401 enters the outer frame 101. When the pressure inside the outer frame 101 is too high, the magnetic plug 402 will not be able to move further, while the circular plate 403 will continue to move. At this time, the connecting spring 404 is in a compressed state, and the magnetic switch 409 moves together with the circular plate 403 through the fixing frame 407, so that the magnetic switch 409 cannot sense the magnetic plug 402. 2. At this time, the staff turns on the power of the sound and light alarm 408. When the outer frame 101 leaks the gas inside due to an accident during transportation, the gas leakage will cause the clamping and fixing component 2 to be unable to effectively clamp the cigarette package, and will also affect the fixed state of the stacked outer frames 101. At this time, the magnetic plug 402 will move under the thrust of the connecting spring 404, so that the magnetic switch 409 can be magnetically sensed by the magnetic plug 402, and then the sound and light alarm 408 is turned on, which serves as a reminder to the staff and prompts them to come for processing.

[0053] The upper and lower side walls of the outer frame 101 are fixedly connected with magnetic pads 5 for improving the adsorption force of the outer frame 101. The upper side walls of multiple outer frames 101 are provided with cover plates 6. The cover plates 6 only retain the mounting holes 301 and the plug-in holes 311 structures of the lower side walls of the outer frame 101, which are only for protecting the cigarette packs of the uppermost outer frame 101.

[0054] The working principle of the present invention is:

[0055] First, the cigarette packs are placed in the multiple grooves of the inner frame 104 by an automatic conveying device. The automatic conveying device is a prior art and will not be described in detail here. After the grooves of a single inner frame 104 are filled, the staff places a new outer frame 101 on top of the original outer frame 101, and then continues to place cigarette packs, and cooperates with the magnetic adsorption of the magnetic pad 5 to achieve stacking of multiple outer frames 101;

[0056] When the outer frames 101 are stacked, the insert tube 302 is inserted into the mounting hole 301, so that the push rod 307 pushes the two top plates 305 to separate from each other, so that the two top plates 305 are not in contact with the sealing ring plate 303. At this time, the top of the insert tube 302 is in contact with the sealing ring plate 303, so that the seal between the insert tube 302 and the mounting hole 301 is achieved, and finally the cover plate 6 is placed on the top;

[0057] Afterwards, the staff uses an air pump that generates inert gas to connect to the air intake fixed pipe 105, and pumps air into the one-way air intake pipe 102. The gas enters the inner frame 104 through the air delivery channel 103 and the air intake fixed pipe 105, and then enters the support pipe 201 through the inner frame 104, driving the two pistons 202 to separate. At the same time, the piston 202 pushes the thread groove 205 of the rotating pipe 203 through the square rod 204 and the guide rod 206, so that the thread groove 205 rotates. The thread groove 205 drives the clamping plate 208 to turn upward through the transmission rod 207. When the clamping plate 208 turns upward, the cigarette pack can be clamped. As the cigarette pack is gradually clamped, the air pressure inside the inner frame 104 gradually increases.

[0058] When the insert 302 is completely inserted into the mounting hole 301, the interiors of the multiple outer frames 101 and the inner frame 104 are all connected. When the air pressure filled into the outer frame 101 is relatively high, the clamping and fixing assembly 2 can clamp and fix the cigarette pack. In addition, the air pressure can also push the movable plug 309 to move, so that the movable plug 309 drives the limiting rod 310 to be inserted into the insertion hole 311. At this time, the connection between the two outer frames 101 is realized. At this time, the staff can judge whether the two outer frames 101 are connected in place by observing the insertion hole 311.

[0059] When the outer frame 101 leaks due to accidental gas during transportation, the magnetic plug 402 will move under the thrust of the connecting spring 404, so that the magnetic switch 409 can be magnetically sensed by the magnetic plug 402, and then the sound and light alarm 408 is turned on, which serves as a reminder for the staff and prompts them to come for processing.

[0060] 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.
