Description

Technical Field

[0001] This utility model relates to the field of dry ice bag packing technology, and in particular to a centering and stacking mechanism for dry ice bags. Background Technology

[0002] Dry ice packs are refrigeration devices that use solid carbon dioxide (dry ice) as the refrigerant. Dry ice blocks are packaged in individual bags and are primarily used to maintain extremely low temperatures for short periods to preserve items requiring deep freezing (such as fresh food, medical samples, vaccines, and biological agents). They are commonly used in the cold chain transportation industry for food and pharmaceuticals, offering both high-efficiency cold preservation and environmentally friendly, residue-free characteristics. After being packaged on the production line, the dry ice blocks still need to be placed in insulated boxes for storage. Currently, this step is done manually, which is inefficient and inefficient, and labor costs are high.

[0003] Chinese utility model patent CN220221310U discloses an automated dry ice packing system, including a feeding conveyor line, a chain conveyor frame at one end of the feeding conveyor line, a processing table next to the chain conveyor frame, a handling robot on a handling platform next to the processing table, and box guide plates on both sides of the handling platform. A material box is slidably mounted inside the box guide plate. Protective railings are provided on the outer sides of the chain conveyor frame, processing table, handling platform, and box guide plates. This utility model uses the feeding conveyor line and chain conveyor frame to horizontally transport dry ice bags. Then, a certain number of dry ice bags are grabbed and moved to the processing table by the transverse conveying mechanism on the chain conveyor frame. Finally, the handling robot on the handling platform next to the processing table moves the products into the material box, completing the active packing of dry ice bags. Using this equipment can free up operators, who only need to change the material box, resulting in high packing efficiency.

[0004] The worktable is primarily used for stacking a specified number of dry ice bags, allowing a transport robot on the adjacent handling platform to move the products into the storage bin. According to paragraph

[0026] of the instruction manual, the worktable's specific structure includes a limiting guardrail on the upper outer side, facilitating the restriction of the upper outer side of the worktable and improving the safety of storing the dry ice bags. Therefore, because the fiber guardrail is fixed, the worktable can only be used for stacking a specified number of dry ice bags. If the stacking quantity changes (for example, traditionally five dry ice bags are stacked together, but now eight dry ice bags are required to accommodate different insulated boxes), then a corresponding width of limiting guardrail and worktable needs to be replaced to better restrict the stacking of the dry ice bags on the worktable. The structure of this worktable is not only unable to accommodate the stacking of dry ice bags of various sizes, but also cannot effectively limit and clamp the sides of the dry ice bag group. This results in gaps that cause some dry ice bags to tilt, making it impossible for the subsequent handling robot to accurately grasp and transport them.

[0005] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this utility model is to overcome the problems of the prior art and provide a centering and stacking mechanism for dry ice bags. This mechanism solves the technical problem that the existing cooking table structure is not only unable to adapt to the stacking of dry ice bags of various sizes, but also cannot effectively limit and clamp the two sides of the dry ice bag group, which easily leads to the dry ice bags tilting due to gaps, making it impossible for the subsequent handling robot to accurately clamp and transport them.

[0007] The above objectives are achieved through the following technical solutions:

[0008] A centering and stacking mechanism for dry ice bags includes a centering platform with a left baffle and a right baffle symmetrically arranged on the platform. The left baffle and the right baffle form a stacking position. The left baffle and the right baffle are driven by a centering drive component to move synchronously in opposite directions or in the opposite direction.

[0009] Furthermore, the centering platform includes a vertically arranged platform and a rear baffle; the centering drive assembly includes a support plate disposed on the back of the rear baffle, and a bracket that can be fitted onto a gear short shaft is provided on the support plate; the other end of the gear short shaft is fixedly connected to the back of the rear baffle, and a synchronizing gear is movably fitted on the gear short shaft; an upper rack and a lower rack are respectively meshed on the upper and lower sides of the synchronizing gear, and the upper rack and the lower rack are respectively connected to the right baffle and the left baffle.

[0010] Furthermore, the short shaft of the gear is located at the axial center of the rear baffle.

[0011] Furthermore, a slide rail is horizontally arranged on the back of the rear baffle, and a left slider and a right slider are symmetrically arranged on the slide rail. A left support plate is connected to the left slider, and the left support plate is connected to the lower rack and the left baffle respectively. A right support plate is connected to the right slider, and the right support plate is connected to the upper rack and the right baffle respectively.

[0012] Furthermore, a left hinge portion is provided on the left support plate, a right hinge portion is provided on the right support plate, and telescopic push rods are provided on the left hinge portion and the right hinge portion.

[0013] Furthermore, the left baffle and the right baffle are identical in size and are both Z-shaped, including a baffle bottom plate parallel to the platform, a baffle vertical plate perpendicular to the baffle bottom plate, and a baffle top plate perpendicular to the baffle vertical plate and extending to the outside of the rear baffle; the baffle top plate can be connected to the left support plate and the right support plate; and a side baffle is vertically arranged on the baffle bottom plate.

[0014] Furthermore, the bottom of the platform is symmetrically provided with translation sliders that can match the translation slide rail.

[0015] Furthermore, a linear actuator is provided between the two translation slide rails, and the execution slider of the linear actuator is connected to the bottom of the support plate.

[0016] This invention provides a centering and stacking mechanism for dry ice bags. It features symmetrically arranged left and right baffles on a centering platform, forming an adjustable stacking area between the baffles for storing dry ice bags. This centering and stacking mechanism is not only simple in structure and offers excellent control, but it also enables the centering and compaction of dry ice bags stacked in the stacking area, ensuring precise gripping and handling by the robot.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. The described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] like Figure 1 and Figure 2 As shown, this solution provides a centering and stacking mechanism for dry ice bags, including a centering platform 1. A left baffle 3 and a right baffle 4 are symmetrically arranged on the centering platform 1. The left baffle 3 and the right baffle 4 form a stacking position 2 for stacking dry ice bags. The left baffle 3 and the right baffle 4 are driven by a centering drive component 5 to move synchronously in opposite directions or in the opposite direction.

[0029] By driving the left baffle 3 and the right baffle 4 to move synchronously in opposite directions through the centering drive component 5, the stacking area of ​​the stacking position 2 can be expanded, which is convenient for stacking dry ice bags of various specifications and quantities.

[0030] After the dry ice bags are stacked, the centering drive component 5 drives the left baffle 3 and the right baffle 4 to move synchronously in opposite directions. This can clamp the left and right sides of the dry ice bags on the stacking position 2 and press each dry ice bag towards the center at the same time, achieving the purpose of centering and stacking the material. This facilitates the stable gripping and material transfer of the subsequent mechanical grippers.

[0031] In this embodiment, the centering platform 1 includes a vertically arranged platform 101 and a rear baffle 102; the centering drive assembly 5 includes a support plate 501 disposed on the back of the rear baffle 102, and a bracket 502 that can be sleeved on the support plate 501; the other end of the gear short shaft 503 is fixedly connected to the back of the rear baffle 102, and a synchronous gear 504 is movably sleeved on the gear short shaft 503; the upper and lower sides of the synchronous gear 504 are respectively meshed with an upper rack 505 and a lower rack 506, and the upper rack 505 and the lower rack 506 are respectively connected to the right baffle 4 and the left baffle 3.

[0032] By rotating the synchronous gear 504 counterclockwise, the upper rack 505 and the lower rack 506 can be driven to drive the right baffle 4 and the left baffle 3 to move synchronously in opposite directions, thereby adjusting the area of ​​the stacking position 2, mainly the length.

[0033] Furthermore, the clockwise rotation of the synchronous gear 504 enables the upper rack 505 and the lower rack 506 to drive the right baffle 4 and the left baffle 3 to move synchronously in opposite directions. This allows the left baffle 3 and the right baffle 4 to simultaneously apply pressure to the left and right sides of several dry ice bags stacked on the stacking position 2, pressing them towards the center to achieve the purpose of centering and stacking the materials.

[0034] In this embodiment, the gear short shaft 503 is located at the axial center of the rear baffle 102 to achieve better positional alignment.

[0035] It should be noted that in this embodiment, the synchronous gear 504 and the gear short shaft 503 are movably connected by a ball bearing 507.

[0036] like Figure 1 and Figure 2 As shown, a slide rail 508 is horizontally arranged on the back of the rear baffle 102, and a left slider 509 and a right slider 510 are symmetrically arranged on the slide rail 508. A left support plate 511 is connected to the left slider 509, and the left support plate 511 is connected to the lower rack 505 and the left baffle 3 respectively. A right support plate 512 is connected to the right slider 510, and the right support plate 512 is connected to the upper rack 505 and the right baffle 4 respectively. By setting a horizontal slide rail mechanism, the movement of the left baffle 3 and the right baffle 4 can be more smoothly supported.

[0037] Furthermore, a left hinge portion 513 is provided on the left support plate 511, and a right hinge portion 514 is provided on the right support plate 512. Telescopic push rods 515 are provided on both the left hinge portion 513 and the right hinge portion 514. In this embodiment, the telescopic push rod 515 can be an electric telescopic push rod, a hydraulic telescopic push rod, or a pneumatic telescopic push rod, etc. Through horizontal telescopic movement, it can drive the upper rack 505 and the lower rack 506 to move synchronously in opposite directions relative to the synchronous gear 504, thereby driving the left baffle 3 and the right baffle 4 to move synchronously in opposite directions.

[0038] The left baffle 3 and the right baffle 4 are identical in size and are both Z-shaped, including a baffle bottom plate 6 parallel to the platform 101, a baffle vertical plate 7 perpendicular to the baffle bottom plate 6, and a baffle top plate 8 perpendicular to the baffle vertical plate 7 and extending to the outside of the rear baffle 102; the baffle top plate 8 can be connected to the left support plate 511 and the right support plate 512.

[0039] The bottom plate 6 of the baffle is vertically provided with side baffles 9, and the two side baffles 9 can press down the left and right sides of the several dry ice bags stacked on the stacking position 2.

[0040] like Figure 2 and Figure 3 As shown, in this embodiment, the bottom of the platform 101 is symmetrically provided with translation sliders 11 that can match the translation slide rails 10. The two translation sliders 11 can drive the centering platform 1 to translate relative to the two translation slide rails 10, thereby driving the centering platform 1 to move forward or backward, so as to better cooperate with the intelligent motion control of the dry ice bag stacking system.

[0041] Furthermore, a linear actuator 12 is provided between the two translation slide rails 10, and the actuator slider 13 of the linear actuator 12 is connected to the bottom of the support plate 501. Driven by the linear actuator 12, the actuator slider 13 can drive the centering platform 1 to move smoothly along the two translation slide rails 10.

[0042] The above description is only for illustrating the embodiments of this utility model and is not intended to limit this utility model. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
