Description

Technical Field

[0001] The present invention relates to the technical field of dry ice bag packing, and in particular to an automatic dry ice bag packing system. Background Art

[0002] Dry ice bags are refrigeration tools that use solid carbon dioxide (dry ice) as a refrigeration medium. Dry ice blocks are packed in individual packaging bags and used to maintain an extremely low temperature environment in a short period of time to preserve items that require deep freezing (such as fresh food, medical samples, vaccines, biological agents, etc.). They are often used in cold chain transportation industries such as food and medicine, and have both efficient cold preservation and environmental protection and no residue. After the dry ice blocks are packed into packaging bags on the production line, they need to be placed in an insulated box for thermal insulation storage. In the existing technology, this step is done manually, which is very inefficient and has high labor costs.

[0003] The Chinese utility model patent with publication number CN220221310U discloses an automatic packing system for dry ice, including a feeding conveyor line, a chain conveyor frame is provided at one end of the feeding conveyor line, a cooking table is provided next to the chain conveyor frame, a handling robot is provided on the transporting table next to the cooking table, and box guide plates are provided on both sides of the transporting table, a material box is slidably provided on the inner side of the box guide plate, and protective fences are provided on the outer sides of the chain conveyor frame, the cooking table, the transporting table and the box guide plate. The present invention uses the feeding conveyor line and the chain conveyor frame to horizontally transport the dry ice bags, and then grabs and moves a certain number of dry ice bags to the cooking table through the transverse conveying mechanism on the chain conveyor frame, and then transports the products to the material box through the handling robot provided on the transporting table next to the cooking table, completing the active packing processing of the dry ice bags, so that the use of this set of equipment can liberate the operator, and the operator only needs to change the material box, and the packing efficiency is high.

[0004] The transfer of dry ice bags by this system involves grasping them from the chain plate conveyor rack to the cooking table, and using a handling robot to grasp and transport the dry ice bags on the cooking table to the bin. Due to the particularity of dry ice bags, using the method of multiple grasps is very likely to cause damage to the packaging bag, such as puncturing the packaging bag. In addition, in order to stack the maximum number of dry ice bags in the bin, it is necessary to perform centering stacking before entering the bin to minimize the gap between adjacent dry ice bags, thereby facilitating the filling of the bin. The Chinese utility model patent with the publication number CN220221310U does not provide any technical solutions to solve the above problems. It only describes grasping and moving a certain number of dry ice bags to the cooking table through a horizontal conveying mechanism, and then using a handling robot provided on the handling platform beside the cooking table to transport the products into the bin. Although this system involves a cooking table, it does not have the function of centering and stacking several dry ice bags. When packing into the bin, using a separate handling robot device is expensive and occupies space. Although the fixture structure at the end of the handling robot for clamping dry ice bags is not specifically described, the currently common one on the market is a synchronous cylinder gripper, which drives the left and right grippers through a double cylinder, and drives the grippers to open and close symmetrically by the synchronous reverse movement of the left and right push plates. Due to the use of a double cylinder structure, if the retraction speeds of the two cylinders or the air pressure in the air circuit are inconsistent, the workpiece cannot be stably centered, resulting in the problem of "left and right deviation", that is, the difference in the retraction speed of the cylinders will cause the workpiece to deviate to the side with a slower speed, and external slight thrust or mechanical inertia may break the force balance, causing the overall movement of the gripper and the workpiece, forming a new unstable balance, thus resulting in the inability to center and clamp the dry ice bags, and further causing the inability to accurately stack them at the specified coordinate position during subsequent packing into the bin. In addition, due to the characteristics of dry ice bags, the synchronous cylinder gripper needs to overcome the problems of low temperature and sublimation when clamping dry ice bags. In a low-temperature environment, it is easy for the air circuit of the synchronous cylinder gripper to freeze or become blocked, and the gaseous carbon dioxide generated by the sublimation of dry ice may enter the cylinder, resulting in damage to the seal or instability of the air pressure system.

[0005] Therefore, there is an urgent need for a new technical solution to solve the above technical problems. Summary of the Invention

[0006] The purpose of the present invention is to overcome the above problems of the prior art, and provides an automatic dry ice bag packing system, which is used to solve the problems that the existing dry ice bag packing system has a complex structure, occupies a large space, multiple grasps of dry ice bags during transfer are likely to cause damage and leakage of the packaging bag and inability to perform centering stacking before packing into the bin, as well as the high cost of using an independent handling robot, and the technical problems that when using a synchronous cylinder gripper, if the retraction speeds of the two cylinders or the air pressure in the air circuit are inconsistent, the workpiece cannot be stably centered, resulting in the phenomenon of "left and right deviation", and the air circuit is easily affected by the low temperature and sublimation of dry ice bags.

Detailed implementation mode

[0020] The present invention will be further described in detail below with reference to the drawings and embodiments. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0021] As Figures 1 to 4 shown, this solution provides a dry ice bag automatic boxing system, including a first bracket 8 and a second bracket 9 arranged in a T - shape, and bin placement positions 10 for placing bins 11 are provided on both sides of the second bracket 9; A chain plate conveying component 1 for intermittently conveying dry ice bags is arranged on the first bracket 8, and a centering and stacking component 2 and a centering and clamping component 5 are arranged on the second bracket 9; It also includes a pushing tooth plate component 4 that can synchronously push a custom number of dry ice bags on the chain plate conveying component 1 to the centering and stacking component 2. The centering and stacking component 2 stacks the pushed dry ice bags in a centered manner to form a dry ice bag module and drives it to translate to the centering and clamping area 12 of the centering and clamping component 5 through the centering and stacking component translation mechanism 3; The centering and clamping component 5, under the drive of the centering translation and lifting mechanism 7, centeringly clamps the dry ice bag module entering the centering and clamping area 12, and drives it into a position adjacent to the bin 11 through the centering and clamping component translation mechanism 6, and then orderly stacks the dry ice bag module into the bin 11 through the drive of the centering translation and lifting mechanism 7.

[0022] Working principle: In this embodiment, the chain plate conveying component 1, the centering and stacking component 2, the centering and clamping component 5, the pushing tooth plate component 4, the centering and stacking component translation mechanism 3, the centering translation and lifting mechanism 7, and the centering and clamping component translation mechanism 6 are all controlled by a central control system.

[0023] The chain plate conveying assembly 1 includes a dry ice bag feeding end 104 that can be connected to the dry ice bag feeding and conveying line. After the dry ice bags enter the chain plate conveying assembly 1 in sequence, they are conveyed at intervals. After the conveyed quantity reaches the customized quantity, the pushing tooth plate assembly 4 operates and horizontally pushes the customized quantity of dry ice bags onto the centering and stacking assembly 2. The centering and stacking assembly 2 centers, compresses, and stacks the received customized quantity of dry ice bags to form a dry ice bag module, and then is driven by the translation mechanism 3 of the centering and stacking assembly to be translated to the centering and clamping area 12; At this time, the centering and clamping assembly 5, under the drive of the centering translation and lifting mechanism 7, centeringly clamps the dry ice bag module that enters the centering and clamping area 12, and is driven by the translation mechanism 6 of the centering and clamping assembly to enter a position adjacent to the material box 11. Then, under the drive of the centering translation and lifting mechanism 7, the dry ice bag module is orderly stacked at the specified coordinate positions in the material box 11 under the control of the specified command.

[0024] As Figure 5 and Figure 6 shown, the chain plate conveying assembly 1 includes a gear chain transmission belt 101 and a number of equally spaced baffles 102 fixed on the gear chain transmission belt 101. A dry ice bag interval 103 for placing dry ice bags is formed between adjacent baffles 102. In this embodiment, the baffle 102 makes a cyclic reciprocating motion along with the transmission of the gear chain transmission belt 101, and can orderly place the dry ice bags input from the dry ice bag feeding and conveying line onto the dry ice bag intervals continuously, thereby facilitating subsequent material transfer.

[0025] In this embodiment, the pushing tooth plate assembly 5 includes a tooth plate 402 with a rack 401. The rack 401 is matched with the dry ice bag interval 103 and can push the dry ice bags located on the dry ice bag interval 103 outwards. A tooth plate top plate 403 is arranged at the top of the tooth plate 402. The tooth plate top plate 403 is connected to the piston end of a tooth plate lifting cylinder 404. The tooth plate lifting cylinder 404 is slidably connected to a tooth plate translation slide rail 407 arranged on a tooth plate bracket 406 through a tooth plate slider 405. The tooth plate bracket 406 is fixedly connected to the first bracket 8. The tooth plate lifting cylinder 404 is also connected to the piston end of a tooth plate push rod 408 arranged on the tooth plate bracket 406.

[0026] Specifically, in this embodiment, the number of the racks 401 on the tooth plate 402 is set according to the quantity of dry ice bags to be pushed each time. Under the coordinated action of the tooth plate lifting cylinder 404 and the tooth plate push rod 408, a number of dry ice bags on a number of the dry ice bag intervals 103 are synchronously pushed outwards, so that they maintain a vertical posture and are accurately shifted onto the centering and stacking assembly 2.

[0027] As an optimization of this embodiment, a tooth plate limit baffle 409 is further provided at the top of the tooth plate 402 for limiting the top of the dry ice bag during pushing.

[0028] As Figures 7 to 9 shown, in this embodiment, the centering and feeding component 2 includes a vertically arranged centering table board 201 and a centering rear baffle 202. Centering left baffles 203 and centering right baffles 204 are symmetrically arranged on the centering table board 201. A centering stacking position 205 for stacking dry ice bags is formed between the centering left baffle 203 and the centering right baffle 204. The centering left baffle 203 and the centering right baffle 204 are respectively driven by a centering synchronous driving mechanism 206 to move in opposite directions synchronously, so as to realize centering and pressing of the dry ice bags on the centering stacking position 205.

[0029] In this embodiment, the size of the centering stacking position 205 can be realized by the synchronous control of the centering synchronous driving mechanism 206 on the centering left baffle 203 and the centering right baffle 204. By expanding the centering stacking position 205, the dry ice bags pushed into by the pushing tooth plate assembly 4 can be better received. By contracting the centering stacking position 205, the centering and pressing of the dry ice bags on the centering stacking position 205 can be better realized.

[0030] The centering synchronous driving mechanism 206 includes a centering support plate 207 arranged on the back of the centering rear baffle 202. A centering bracket 209 capable of sleeving a gear short shaft 208 is arranged on the centering support plate 207. The other end of the gear short shaft 208 is fixedly connected to the back of the centering rear baffle 202, and a centering synchronous gear 210 is movably sleeved on the gear short shaft 208. An upper rack 211 and a lower rack 212 are respectively engaged with the upper and lower sides of the centering synchronous gear 210. The upper rack 211 and the lower rack 212 are respectively connected to the centering right baffle 204 and the centering left baffle 203. The gear short shaft 208 is arranged at the axial center position of the centering rear baffle 202 to better realize position centering.

[0031] A centering slide rail 213 is horizontally arranged on the back of the centering rear baffle 202. Centering left sliders 214 and centering right sliders 215 are symmetrically arranged on the centering slide rail 213. A centering left support plate 216 is connected to the centering left slider 214. The centering left support plate 216 is respectively connected to the lower rack 212 and the centering left baffle 203. A centering right support plate 217 is connected to the centering right slider 215. The centering right support plate 217 is respectively connected to the upper rack 211 and the centering right baffle 204. A left hinge portion 218 is provided on the centering left support plate 216, a right hinge portion 219 is provided on the centering right support plate 217, and a centering telescopic push rod 220 is provided on the left hinge portion 218 and the right hinge portion 219. In this embodiment, the centering telescopic push rod 220 can be an electric telescopic push rod, a hydraulic telescopic push rod, a pneumatic telescopic push rod, etc. Through horizontal telescopic movement, it can drive the upper rack 211 and the lower rack 212 to move synchronously and in opposite directions relative to the centering synchronous gear 210, thereby driving the centering left baffle 203 and the centering right baffle 204 to move synchronously and in opposite directions. Through this mechanism, the movement of the centering left baffle 203 and the centering right baffle 204 can be better supported stably.

[0032] In this embodiment, the centering left baffle 203 and the centering right baffle 204 have the same specifications and are both in a Z shape, including a centering baffle bottom plate 221 parallel to the centering table plate 201, a centering baffle vertical plate 222 perpendicular to the centering baffle bottom plate 221, and a centering baffle top plate 223 perpendicular to the centering baffle vertical plate 222 and extending to the outside of the centering rear baffle 202; the centering baffle top plate 223 can be connected to the centering left support plate 216 and the centering right support plate 217.

[0033] In addition, a centering side baffle 224 is vertically provided on the centering baffle bottom plate 221, and the two centering side baffles 224 can centeringly press the left and right sides of a number of dry ice bags stacked on the centering stacking position 205.

[0034] As Figure 8 and Figure 9 shown, in this embodiment, the centering material loading assembly translation mechanism 3 includes centering translation sliders 302 symmetrically arranged at the bottom of the centering table plate 201 and capable of matching with the centering translation slide rails 301, and the two centering translation slide rails 301 are respectively fixedly connected to centering fixing plates 303 arranged on the second bracket 9; A centering linear actuator 304 is further arranged between the two centering translation slide rails 301, and an actuator slider 305 of the centering linear actuator 304 is connected to the bottom of the centering support plate 207.

[0035] Driven by the centering linear actuator 304, the two translation sliders 302 can drive the centering table plate 201 to translate relative to the two centering translation slide rails 301, and further drive the centering translation slide rails 301 to move forward or backward.

[0036] As Figures 10 to 14As shown in the figure, in this embodiment, the centering and clamping component 5 includes a clamping seat 501. A gear rotating shaft through hole 502 is provided on the clamping seat 501, and a gear component 503 is arranged in the gear rotating shaft through hole 502. The gear component 503 is driven by a clamping motor 504 arranged outside the clamping seat 501 to rotate clockwise or counterclockwise. Left and right push rod through holes 505 and 506 that can penetrate the gear rotating shaft through hole 502 are symmetrically opened on the left and right sides of the clamping seat 501. A left push rod 507 is movably sleeved in the left push rod through hole 505, and the left end of the left push rod 507 is connected to a left clamping plate 518. A right push rod 508 is movably sleeved in the right push rod through hole 506, and the right end of the right push rod 508 is connected to a right clamping plate 519. The left push rod 507 and the right push rod 508 move in opposite directions under the drive of the gear component 503, and a clamping position 509 is formed between the left clamping plate 518 and the right clamping plate 519.

[0037] Working principle: Before clamping the dry ice bag module, the gear component 503 is driven by the clamping motor 514 to rotate clockwise. The gear component 503 applies the rotational force to the left push rod 507 and the right push rod 508 that are in transmission connection with it. The left push rod 507 and the right push rod 508 respectively drive the left clamping plate 518 and the right clamping plate 519 connected to them to move away from each other in the opposite direction. At this time, the area of the feeding position becomes larger, which is convenient for clamping the dry ice bag module centrally stacked on the centering stacking position 205. It should be noted that when clamping, the left push rod 507 and the right push rod 508 are vertically inserted into both sides of the dry ice bag module, and the outer sides are respectively attached to the centering left baffle 203 and the centering right baffle 204, so as not to damage the dry ice bag module.

[0038] When clamping both sides of the dry ice bag, the gear component 503 is driven by the clamping motor 504 to rotate counterclockwise. The gear component 503 applies the rotational force to the left push rod 507 and the right push rod 508 that are in transmission connection with it. The left push rod 507 and the right push rod 508 respectively drive the left clamping plate 518 and the right clamping plate 519 connected to them to move closer to each other in the opposite direction. At this time, the area of the clamping position 509 becomes smaller, realizing the centering and tightening of both sides of the dry ice bag module for subsequent material transfer and boxing operations.

[0039] It should be noted that in this embodiment, the driving directions of the left push rod 507 and the right push rod 508 when the gear component 503 rotates clockwise or counterclockwise can also be changed according to the actual structure, and perform work opposite to the above working principle, which also belongs to the protection scope of this solution.

[0040] Such as Figure 12 AndFigure 13 As shown, the left push rod through hole 505 includes an upper left push rod through hole 510 and a lower left push rod through hole 511 that are arranged parallel to each other vertically. The right push rod through hole 506 includes an upper right push rod through hole 512 and a lower right push rod through hole 513 that are arranged parallel to each other vertically.

[0041] The gear assembly 503 includes a gear rotating shaft 523, and the gear rotating shaft 523 is respectively movably connected to the upper and lower orifices of the gear rotating shaft through hole 502 through a rotating shaft ball bearing 524; Synchronous gears 525 are arranged on the gear rotating shaft 523 corresponding to the positions of the left push rod 507 and the right push rod 508; by rotating the synchronous gears 525, the left push rod 507 and the right push rod 508 are driven to move in opposite directions, realizing centering clamping or loosening of the dry ice bag.

[0042] The synchronization gear 525 includes an upper synchronization gear 526 corresponding to the upper left push rod 514 and the upper right push rod 516, and a lower synchronization gear 527 corresponding to the lower left push rod 515 and the lower right push rod 517; the upper left push rod 514 and the upper right push rod 516 are arranged in parallel on the front side and the rear side of the upper synchronization gear 526, and driven by the rotation of the upper synchronization gear 525, the upper left push rod 514 and the upper right push rod 516 can perform reverse translation; the lower left push rod 515 and the lower right push rod 517 are arranged in parallel on the front side and the rear side of the lower synchronization gear 527, and driven by the rotation of the lower synchronization gear 527, the lower left push rod 515 and the lower right push rod 517 can perform reverse translation.

[0043] Also, since the upper synchronization gear 526 and the lower synchronization gear 527 perform synchronous rotation driven by the same gear rotating shaft 523, the upper left push rod 514 and the lower left push rod 515 can be driven to perform synchronous reverse movement relative to the upper right push rod 516 and the lower right push rod 517.

[0044] Upper push rod tooth paths 520 capable of meshing with the upper synchronization gear 526 are respectively arranged on the upper left push rod 514 and the upper right push rod 516, and lower push rod tooth paths 521 capable of meshing with the lower synchronization gear 527 are respectively arranged on the lower left push rod 515 and the lower right push rod 517; through the meshing mechanism of the synchronization gear and the tooth path, the translation of the push rod with the tooth path can be driven under the rotation of the gear.

[0045] The clamping motor 504 is fixed by a motor bracket 522 arranged on the top of the clamping seat 501, and the rotating shaft of the clamping motor 504 is fixedly connected to the top end of the gear rotating shaft 523 through a coupling. The clamping motor 504 is a servo motor, which can perform precise rotation control according to the number of dry ice bags to be clamped, and indirectly realize the precise centering adjustment of the clamping position 509 between the left clamping plate 518 and the right clamping plate 519.

By arranging the left guiding rod 530 and the right guiding rod 531, the movement of the left clamping plate 518 and the right clamping plate 519 can be better guided smoothly, making the clamping process of this centering clamping assembly smoother.

[0047] Such asFigure 4 As shown, in this embodiment, the centering and clamping component translation mechanism 6 includes clamping component slide rails 601 symmetrically arranged on the second bracket 9, and clamping component sliders 602 matching the clamping component slide rails 601.
