Description

Technical Field

[0001] This utility model relates to the field of automated production technology, specifically to a device for disassembling and stacking blister trays. Background Technology

[0002] Blister trays, also known as blister trays, are plastic products manufactured using a vacuum forming process. They are often referred to as plastic trays. Made from plastic, these trays undergo a fine processing to create trays with specific grooves. These grooves allow products to be placed properly within them, protecting the products during placement, collection, and transportation, while also enhancing their aesthetic appeal. Furthermore, blister trays play a crucial role in the storage and transportation of products on automated production lines.

[0003] In existing automated production lines, blister trays are stored in stacks. When product materials need to be stored or transported using blister trays, a disassembly mechanism separates each blister tray individually onto a conveyor line. The conveyor line then moves the blister tray to a material handling mechanism, where products are picked up or placed. After the products are picked up or placed, the conveyor line continues to move the blister tray to a stacking mechanism for collection. However, some thinner blister trays, due to their light weight, are prone to positional shifts during conveyor transport. This results in insufficient precision in the material handling mechanism when picking up or placing products into the blister tray, leading to low product handling efficiency.

[0004] Therefore, there is an urgent need for a device for disassembling and folding blister packs to solve the above problems. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide a folding and unfolding device for blister trays, so as to solve the problem of low product handling efficiency caused by positional deviation of thin blister trays during the conveyor line transfer process in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model provides a tray disassembly and stacking device for blister trays, including a tray conveyor line and tray disassembly and stacking mechanisms mounted at both ends of the tray conveyor line; the tray conveyor line includes two relatively parallel crossbeams, the inner sides of the two crossbeams are rotatably connected to conveyor belts, a drive unit is installed below the crossbeams, and the drive unit is driven and connected to the conveyor belts; a positioning cylinder is provided on the outer side of the crossbeams along the Y-axis direction, and a positioning block is connected to the telescopic end of the positioning cylinder; the positioning block has a "7" shaped structure; a blocking cylinder is vertically mounted below the space between the two crossbeams.

[0008] The disassembly mechanism is used to lower the blister trays onto the conveyor belt, and the stacking mechanism is used to stack and collect the blister trays containing the material to be picked up and placed.

[0009] As an optional technical solution for a blister tray disassembly and folding device, the disassembly mechanism includes a first lifting cylinder mounted below the material tray conveyor line, and a first lifting plate installed at the telescopic end of the first lifting cylinder; first limiting components are respectively installed on two crossbeams located on both sides of the first lifting cylinder, and the blister tray is placed on the two first limiting components.

[0010] As an optional technical solution for a blister tray stacking and unstacking device, the first limiting component includes a limiting cylinder arranged on a crossbeam along the Y-axis direction; the telescopic end of the limiting cylinder is equipped with a first limiting block, which has an "L" shaped structure.

[0011] As an optional technical solution for a blister tray stacking device, the limiting component is symmetrically equipped with first guide members on its left and right sides, and the top and bottom of the first guide members are respectively equipped with first fiber optic sensors.

[0012] As an optional technical solution for a stacking and unstacking device for blister trays, the stacking mechanism includes a second lifting cylinder mounted below the material tray conveyor line, and a second lifting plate is installed on the telescopic end of the second lifting cylinder; a second limiting component is respectively installed on two crossbeams located on both sides of the second lifting cylinder, and the blister trays are stacked on the second limiting components.

[0013] As an optional technical solution for a blister tray stacking device, the second limiting component includes a limiting seat mounted on the crossbeam, and a second limiting block is rotatably connected to the limiting seat, with the bottom of the free end of the second limiting block being inclined.

[0015] As an optional technical solution for a blister tray stacking and unstacking device, at least two support columns are installed on the outer sides of the two crossbeams respectively.

[0016] The beneficial effects of this utility model are as follows:

[0017] This utility model provides a tray disassembly and stacking device for blister trays, including a tray conveyor line and tray disassembly and stacking mechanisms mounted at both ends of the tray conveyor line; the tray conveyor line includes two relatively parallel crossbeams, the inner sides of the two crossbeams are rotatably connected to conveyor belts, a drive unit is installed below the crossbeams, and the drive unit is driven and connected to the conveyor belts; a positioning cylinder is provided on the outer side of the crossbeams along the Y-axis direction, and a positioning block is connected to the telescopic end of the positioning cylinder; a blocking cylinder is vertically mounted below the space between the two crossbeams.

[0018] In the above structure, the blister tray is lowered onto the conveyor belt via a disassembly mechanism. The drive unit drives the conveyor belt to move the blister tray toward the stacking mechanism.

This blister tray disassembly and stacking device enables precise transport and positioning of thin blister trays on the tray conveyor line, improving the accuracy and efficiency of the external pick-and-place mechanism in picking up and placing products from the blister tray.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0032] like Figure 1-4As shown, this utility model provides a tray disassembly and stacking device for blister trays. This device includes a tray conveyor line 1 and a tray disassembly mechanism 2 and a tray stacking mechanism 3 mounted at both ends of the tray conveyor line 1. The tray conveyor line 1 includes two parallel crossbeams 10, with conveyor belts 12 rotatably connected to the inner sides of the two crossbeams 10. A drive unit 13 is installed below the crossbeams 10, and the drive unit 13 is connected to the conveyor belts 12. A positioning cylinder 14 is provided on the outer side of the crossbeams 10 along the Y-axis direction, and a positioning block 141 is connected to the telescopic end of the positioning cylinder 14. The positioning block 141 has a "7" shaped structure. A blocking cylinder 15 is vertically mounted below the two crossbeams 10. The tray disassembly mechanism 2 is used to lower the blister trays 16 onto the conveyor belt 12, and the tray stacking mechanism 3 is used to collect the blister trays 16 that have been picked up and placed.

[0033] The present invention provides a blister tray disassembly and stacking device. The blister tray 16 is lowered onto the conveyor belt 12 by the disassembly mechanism 2. The drive unit 13 drives the conveyor belt 12 to move the blister tray 16 toward the stacking mechanism 3. When the blister tray 16 is moved to the lower part of the external material handling mechanism, the telescopic end of the blocking cylinder 15 extends upward, and the drive unit 13 stops the transmission of the conveyor belt 12. At the same time, the positioning cylinder 14 moves the driving positioning block 141 toward the blister tray 16 to push the blister tray 16 to perform position correction. Under the action of the blocking cylinder 15 and the positioning cylinder 14, the blister tray 16 is accurately positioned. After the material handling mechanism picks up and places products on the blister tray 16, the conveyor belt 12 continues to move the blister tray 16 to the stacking mechanism 3, and the stacking mechanism 3 stacks and collects the blister tray 16. The folding and unfolding device for blister trays enables the thin blister trays 16 to be accurately transferred and positioned on the tray conveyor line 1, improving the accuracy and efficiency of the external material handling mechanism in picking up and placing products from the blister trays 16.

[0034] Specifically, such as Figure 1 As shown, two support columns 11 are installed on the two outer sides of the crossbeam 10. Of course, more support columns 11 can be installed according to the length of the material tray conveyor line 1 so that the material tray conveyor line 1 can be stably installed on the workshop or other workbench through the support columns 11. The tray disassembly mechanism 2 and the tray stacking mechanism 3 are arranged opposite to each other at both ends of the material tray conveyor line 1, forming a clearance space between them for manual or external material handling mechanisms (such as robotic arms) to handle the blister tray 16.

[0035] In this embodiment, as Figure 1 and Figure 2As shown, each of the two ends of the inner side of the crossbeam 10 is provided with a linkage wheel. The conveyor belt 12 is wrapped around and connected between the two linkage wheels. The drive unit 13 includes a drive motor mounted on the bottom of the two crossbeams 10. A drive shaft is rotatably connected between the two crossbeams 10. Each end of the drive shaft is provided with a drive wheel, and the drive wheel is provided with knurling. Gears are provided on the output shaft of the drive motor and the drive shaft, and the drive motor is driven and connected to the drive shaft through the gears. Tensioning wheels are installed on the crossbeams 10 on the left and right sides of the drive shaft. The bottom of the conveyor belt 12 abuts against the drive wheel and is adjusted to move closer to the drive wheel by the two tensioning wheels, thus tensioning the conveyor belt 12 so that it is tightly attached to the drive wheel. As a result, the drive wheel can achieve synchronous movement of the two conveyor belts 12 under the drive of the drive motor.

[0036] In this embodiment, as Figure 2 As shown, the disassembly mechanism 2 includes a base plate connected to the bottom of two crossbeams 10. A first lifting cylinder 20 is vertically mounted on the base plate. A first lifting plate 201 is horizontally positioned at the telescopic end of the first lifting cylinder 20. The first lifting cylinder 20 drives the first lifting plate 201 to move up and down, thereby moving the blister tray 16 up and down. First limiting components 21 are respectively installed on the crossbeams 10 on both sides of the first lifting cylinder 20. The first limiting component 21 consists of a limiting cylinder 210 arranged along the Y-axis direction on the crossbeam 10 and a first limiting block 211 connected to the telescopic end of the limiting cylinder 210. The first limiting block 211 has an "L" shape. The limiting cylinder 210 drives the first limiting block 211 to move telescopically along the Y-axis direction, allowing the two first limiting blocks 211 to achieve... The system limits and lifts multiple blister trays 16 or lowers the blister trays 16 into the first lifting plate 201. In this structure, when it is necessary to lower the blister trays 16 onto the conveyor belt 12, the first lifting cylinder 20 first drives the first lifting plate 201 to move upward to drive the blister trays 16 upward. The two limiting cylinders 210 simultaneously drive the first limiting block 211 to move away from the blister trays 16. The first lifting cylinder 20 retracts to move the multiple blister trays 16 downward to a target stroke, so that the limiting cylinder 210 can drive the first limiting block 211 to insert into the bottom of the second to last blister tray 16 to limit and lift the blister trays 16 above it. Finally, the first lifting cylinder 20 continues to move downward and lowers the blister trays 16 on the first lifting plate 201 onto the conveyor belt 12.

[0037] Furthermore, the first limiting component 21 is symmetrically equipped with first guide members 22 on its left and right sides, allowing manual or robotic arms to neatly place multiple blister trays 16 on the first limiting block 211 under the guidance of the first guide members 22 for tray removal operations; the top and bottom of the first guide members 22 are respectively equipped with first fiber optic sensors 220, and the operators can more intuitively know the maximum and minimum number of blister trays 16 on the tray removal mechanism 2 through the setting of the two first fiber optic sensors 220.

[0038] In this embodiment, as Figure 3 and Figure 4 As shown, the stacking mechanism 3 includes a base plate connected to the bottom of two crossbeams 10. A second lifting cylinder 30 is vertically mounted on the base plate. A second lifting plate 301 is horizontally positioned at the telescopic end of the second lifting cylinder 30. The second lifting cylinder 30 drives the second lifting plate 301 to move up and down, thereby moving the blister tray 16 on the conveyor belt 12 upward. Two sets of second limiting components 31 are respectively provided on the crossbeams 10 on both sides of the second lifting cylinder 30. The second limiting component 31 consists of a limiting seat 310 and a second limiting block 311 that can be rotatably connected to the limiting seat 310 upward. The second limiting block 311 is in the shape of a "7". Specifically, as shown... Figure 4 As shown, the limiting seat 310 has a clearance position, and the second limiting block 311 is placed in the clearance position, with its upper end connected to the limiting seat 310 via a rotating shaft; the top of the second limiting block 311 is inclined near the top of the clearance position, and the bottom of its free end is also inclined. In this structure, when the second lifting plate 301 lifts the blister tray 16 on the conveyor belt 12 upward through the second lifting cylinder 30, the two sides of the blister tray 16 abut against the inclined part at the bottom of the free end of the second limiting block 311 and move upward. At this time, the second limiting block 311... 11. The upward rotation provides space for the blister tray 16 to move upward. When the blister tray 16 is lifted to the upper end of the second limiting block 311, the second lifting cylinder 30 retracts and resets, and the blister tray 16 will fall onto the four second limiting blocks 311 for stacking and collection. Since the lower part of the second limiting block 311 abuts against the inner wall of the clearance space, the second limiting block 311 will not rotate downward when it receives the downward gravity of the blister tray 16. That is to say, the second limiting block 311 only achieves upward unidirectional rotation on the limiting seat 310.

[0039] Furthermore, the second limiting component 31 is symmetrically equipped with second guide members 32 on its left and right sides. Under the guidance of multiple second guide members 32, the blister trays 16 can be neatly and orderly stacked and collected on multiple second limiting blocks 311. The top and bottom of the guide members are respectively equipped with second fiber optic sensors 320. Through the setting of two second fiber optic sensors 320, the operator can more intuitively know the maximum and minimum number of blister trays 16 on the stacking mechanism 3.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
