Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a rotary bag-dropping device and a transfer device. Background Technology

[0002] With the rapid development of industry, the demand for personalized customization in large-volume parenteral solutions production is increasing. In soft bag production lines, the circular belt conveyor system can only achieve horizontal movement of the bag, resulting in a fixed orientation of the two sides of the soft bag. This cannot meet the specific placement requirements of some pharmaceutical companies for the sterilization / printing side of the soft bag during output. Conventional production lines use a horizontal clamping structure to remove the bag, which cannot flexibly adjust the orientation of the two sides of the soft bag when docking with the bag sorting ring.

[0003] Therefore, how to effectively improve the problem in the existing technology that it is impossible to flexibly adjust the orientation of the two sides of the soft bag when it is connected to the bag ring is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a rotary bag-feeding device and a transfer device, which can effectively improve the problem in the prior art that the orientation of the two sides of the soft bag cannot be flexibly adjusted when docking with the bag-feeding ring.

[0005] To achieve the above objectives, this utility model provides a rotary bag-feeding device, comprising:

[0006] A fixed plate is used to connect to a drive device, which drives the fixed plate to reciprocate above the first and second workstations.

[0007] The rotating assembly includes a slide rail connected to a fixed plate, a slider slidably connected to the slide rail and capable of moving along the extension direction of the slide rail, and a rack fixedly connected to the slider.

[0008] Several gripping components are rotatably connected to a fixed plate. Each gripping component includes a gear that meshes with a rack and a pneumatic gripper connected to the gear. The pneumatic gripper is used to grip the product at the first station. A sliding member is used to drive the rack to move after the pneumatic gripper grips the product. The gear drives the pneumatic gripper and the product to rotate around the axis of the gear by a preset angle and then transfers the product to the second station.

[0009] In one possible implementation, the fixing plate is fixedly connected to a first mounting plate and a second mounting plate, which are spaced apart in the extension direction of the slide rail. One end of the slide rail is fixedly connected to the first mounting plate, and the other end of the slide rail is fixedly connected to the second mounting plate, so that the slide rail is fixed relative to the fixing plate.

[0010] In one possible implementation, bearings are provided between the gripping assembly and the fixing plate. The bearings include an inner bearing ring and an outer bearing ring that can rotate relative to each other. The outer bearing ring is fixedly connected to the fixing plate, and the inner bearing ring is fixedly connected to the gripping assembly. The gear is located below the bearing and is coaxially arranged with the bearing.

[0011] In one possible implementation, the gripping assembly further includes a connector, which includes a base and a shaft with one end connected to the base. The base is fixedly connected to the inner ring of the bearing, and the other end of the shaft passes through the inner ring and the inner hole of the gear to connect to the pneumatic gripper located below the gear. The shaft and the inner hole of the gear are connected by a key to drive the pneumatic gripper to rotate relative to the fixed plate when the gear rotates.

[0012] In one possible implementation, the rotating assembly further includes a third mounting plate having opposing first and second sides, the first side of the third mounting plate being fixedly connected to a slider, and the second side of the third mounting plate being fixedly connected to a rack so that the rack is fixed relative to the slider.

[0013] In one possible implementation, the pneumatic gripper includes a drive unit, a first gripper and a second gripper connected to the drive unit, the first gripper and the second gripper being disposed opposite to each other, and the drive unit being able to drive the first gripper and the second gripper to move closer to each other and further away from each other to grip and release the product.

[0014] In one possible implementation, there is one rack, the rack extends in a direction parallel to the slide rail, and the rack meshes with all the gears.

[0015] In one possible implementation, there are multiple racks, and each rack corresponds to a gear.

[0016] In one possible implementation, the gripping components are evenly arranged on the fixed plate along a preset direction, which is parallel to the extension direction of the slide rail.

[0017] Based on the above, this application also provides a transfer device, including a drive device and a rotary bag-dropping device, wherein the drive device can drive a fixed plate to reciprocate above a first station and a second station.

[0018] Compared with the prior art, the technical solution provided by this utility model has at least the following beneficial effects: both the rotating component and the gripping component are connected to the fixed plate, so that when the driving device moves the fixed plate, it drives the rotating component and the gripping component to move synchronously. The sliding component of the rotating component can move along the extension direction of the slide rail of the rotating component, thereby driving the rack fixedly connected to the sliding component to move along the extension direction of the slide rail of the rotating component. The gripping component is rotatably connected to the fixed plate. When the rack moves along the extension direction of the slide rail of the rotating component, it can drive the gear meshing with the rack in the gripping component to rotate around its own axis, thereby driving the pneumatic gripper connected to the gear to rotate around the axis of the gear. During the process of the pneumatic gripper moving towards the second station under the indirect drive of the driving device after gripping the product at the first station, the orientation of the product can be adjusted by indirectly driving the pneumatic gripper and the product to rotate through the movement of the sliding component. This can effectively improve the problem in the prior art that it is impossible to flexibly adjust the orientation of the two sides of the soft bag when docking with the bag sorting ring.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the position 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 of this utility model.

[0036] The purpose of this invention is to provide a rotary bag-feeding device and a transfer device, which can effectively improve the problem in the prior art that the orientation of the two sides of the soft bag cannot be flexibly adjusted when docking with the bag-feeding ring.

[0037] Please see Figures 1 to 5To achieve the above objectives, this utility model provides a rotary bag-feeding device, including a fixed plate 100, a rotating assembly 500, and several gripping assemblies. The fixed plate 100 is connected to a driving device 200, which drives the fixed plate 100 to reciprocate above the first station 300 and the second station 400. The driving device 200 can drive the fixed plate 100 to move laterally in the horizontal plane and also drive the fixed plate 100 to rise and fall in the height direction. For example, after the driving device 200 drives the fixed plate 100 to move laterally in the horizontal plane above the first station 300, it can drive the fixed plate 100 to move down toward the first station 300 to a preset height to perform an action. Afterward, it drives the fixed plate 100 to move up and then laterally in the horizontal plane above the first station 300.

[0038] The rotating assembly 500 includes a slide rail 510 connected to a fixed plate 100, a slider 520 slidably connected to the slide rail 510 and movable along the extension direction of the slide rail 510, and a rack 530 fixedly connected to the slider 520. The slide rail 510 is fixed relative to the fixed plate 100. A power source drives the slider 520, which is slidably connected to the slide rail 510, to move along the extension direction of the slide rail 510, and can drive the rack 530, which is connected to the slider 520, to move synchronously along the extension direction of the slide rail 510. The moving module composed of the slide rail 510 and the slider 520 can be replaced by a rodless cylinder, a rodless electric cylinder, etc., as long as the rack 530 can reciprocate in the extension direction of the slide rail 510. The extension direction of the slide rail 510 includes the extension direction of the slide rail 510 itself and a direction parallel to the extension direction of the slide rail 510 itself.

[0039] The gripping assembly is rotatably connected to the fixed plate 100. Each gripping assembly includes a gear 610 meshing with a rack 530 and a pneumatic gripper 620 connected to the gear 610. The pneumatic gripper 620 grips the product on the first station 300. The sliding member 520 drives the rack 530 to move after the pneumatic gripper 620 grips the product, causing the gear 610 to rotate the pneumatic gripper 620 and the product around the axis of the gear 610 by a preset angle, thus transferring the product to the second station 400. The gripping assembly is fixed... The plates 100 are evenly arranged along a preset direction, which is parallel to the extension direction of the slide rail 510, so that the gripping components can be rotated when the rack 530 moves along the extension direction of the slide rail 510. Each pneumatic gripper 620 includes a drive unit, a first gripper 621 and a second gripper 622 connected to the drive unit. The first gripper 621 and the second gripper 622 are arranged opposite to each other. The drive unit can drive the first gripper 621 and the second gripper 622 to move closer to each other and further away from each other to grip and put down the product. The number of gripping components can be adjusted according to the actual situation. For example, the number of gripping components can be set to four to transfer four products at a time, or the number of gripping components can be set to six to transfer six products at a time. The sliding member 520 is used to drive the rack 530 to move after the pneumatic gripper 620 grips the product. The timing of the movement of the rack 530 can be any time period when the pneumatic gripper 620 moves from the first station 300 to the second station 400. For example, the rack 530 can be driven to move when the pneumatic gripper 620 grips the product and moves out of the first station 300 and moves towards the second station 400 under the action of the fixed plate 100, or the rack 530 can be driven to move when the pneumatic gripper 620 grips the product and moves out of the first station 300 while the fixed plate 100 remains stationary.

[0040] Both the rotating assembly 500 and the gripping assembly are connected to the fixed plate 100, so that when the driving device 200 moves the fixed plate 100, it also moves the rotating assembly 500 and the gripping assembly synchronously. The sliding member 520 of the rotating assembly 500 can move along the extension direction of the slide rail 510 of the rotating assembly 500, thereby driving the rack 530 fixedly connected to the sliding member 520 to move along the extension direction of the slide rail 510 of the rotating assembly 500. The gripping assembly is rotatably connected to the fixed plate 100. When the rack 530 moves along the extension direction of the slide rail 510 of the rotating assembly 500, it can drive the gear 610 meshing with the rack 530 in the gripping assembly to rotate. The rotation of its own axis drives the pneumatic gripper 620 connected to the gear 610 to rotate around the axis of the gear 610. After the pneumatic gripper 620 grabs the product on the first station 300, it moves towards the second station 400 under the indirect drive of the drive device 200. The movement of the sliding member 520 can indirectly drive the pneumatic gripper 620 and the product to rotate, thereby adjusting the orientation of the product. For example, the product can be flipped 180° to complete the orientation adjustment of both sides of the product. Different displacements of the sliding member 520 can achieve different rotation angles of the gear 610, which can effectively improve the problem in the prior art that it is impossible to flexibly adjust the orientation of both sides of the soft bag when docking with the bag making ring.

[0041] In one possible implementation, the fixing plate 100 is fixedly connected to a first mounting plate 110 and a second mounting plate 120. The first mounting plate 110 and the second mounting plate 120 are spaced apart in the extending direction of the slide rail 510. One end of the slide rail 510 is fixedly connected to the first mounting plate 110, and the other end of the slide rail 510 is fixedly connected to the second mounting plate 120, so that the slide rail 510 is fixed relative to the fixing plate 100. That is, the two ends of the slide rail 510 are fixed by the first mounting plate 110 and the second mounting plate 120, so that the slide rail 510 and the fixing plate 100 are fixedly connected. The distance between the first mounting plate 110 and the second mounting plate 120 can be adjusted according to... The length of the slide rail 510 is adjusted. The first mounting plate 110 is provided with a first fixing hole, the second mounting plate 120 is provided with a second fixing hole, and the slide rail 510 is provided with a third fixing hole corresponding to the first fixing hole and a fourth mounting hole corresponding to the second fixing hole. The first fixing member passes through the corresponding first fixing hole and the third fixing hole to connect the first mounting plate 110 and the slide rail 510. The second fixing member passes through the corresponding second fixing hole and the fourth fixing hole to connect the second mounting plate 120 and the slide rail 510. The first fixing member and the second fixing member can be bolts to improve the efficiency of installation and disassembly, and at the same time facilitate the replacement of worn parts.

[0042] In one possible implementation, a bearing 700 is provided between the gripping component and the fixed plate 100. The bearing 700 includes an inner bearing ring 710 and an outer bearing ring 720 that are rotatable relative to each other. The outer bearing ring 720 is fixedly connected to the fixed plate 100, and the inner bearing ring 710 is fixedly connected to the gripping component. The gear 610 is located below the bearing 700 and is coaxially arranged with the bearing 700. Through the relative rotation of the inner bearing ring 710 and the outer bearing ring 720, the gripping component is rotatably connected to the fixed plate 100. When the fixed plate 100 moves, it can drive the gripping component to move synchronously. At the same time as the fixed plate 100 moves, the gripping component can rotate around the axis of the bearing 700.

[0043] Furthermore, the gripping assembly also includes a connector 630, which includes a base 631 and a shaft 632 connected to the base 631 at one end. The base 631 is fixedly connected to the inner ring 710 of the bearing. The base 631 has a disc-shaped structure, and the fixing plate 100 has a groove for accommodating the base 631. A fifth fixing hole with an extension direction parallel to the axis of the bearing 700 is opened in the circumferential direction of the base 631. A sixth fixing hole corresponding to the fifth fixing hole is opened in the inner ring 710 of the bearing. A third fixing member passes through the corresponding fifth and sixth fixing holes to realize the connection between the base 631 and the inner ring 710 of the bearing. The third fixing member can be a bolt to improve the installation and disassembly efficiency and facilitate the replacement of worn parts. The other end of the shaft 632 passes through the inner ring and the inner hole of the gear 610 to connect... The pneumatic gripper 620 is located below the gear 610. Specifically, the pneumatic gripper 620 is connected to a pneumatic gripper 620 fixing plate 100, which is located between the pneumatic gripper 620 and the gear 610. The other end of the shaft 632 passes through the inner ring and the inner hole of the gear 610 and connects to the pneumatic gripper 620 fixing plate 100, thus realizing the connection between the shaft 632 and the pneumatic gripper 620. The shaft 632 and the inner hole of the gear 610 are connected by a key to limit the axial and circumferential movement of the gear 610 and the shaft 632, ensuring that the gear 610 can drive the shaft 632 to rotate synchronously when it rotates. In turn, the gear 610 drives the pneumatic gripper 620 to rotate relative to the fixing plate 100 when it rotates. The operation is stable and reliable, requires little space, and is flexible in installation and use, improving the degree of freedom in production.

[0044] In one possible implementation, the rotating assembly 500 further includes a third mounting plate 540 having opposing first and second sides. The first side of the third mounting plate 540 is fixedly connected to the slider 520, and the second side of the third mounting plate 540 is fixedly connected to the rack 530, so that the rack 530 is fixed relative to the slider 520. The rack 530 is located on one side of the gear 610, and the third mounting plate 540 is located on the side of the rack 530 away from the gear 610. The third mounting plate 540 and the rack 530, as well as the third mounting plate 540 and the slider 520, can be connected by bolts to facilitate the maintenance and replacement of the rack 530. The rack 530 is typically a standard part, and the meshing between the rack 530 and the gear 610 can be effectively ensured by adjusting the thickness between the first and second sides of the third mounting plate 540.

[0045] In one possible implementation, there is one rack 530, the extension direction of the rack 530 is parallel to the extension direction of the slide rail 510, and the rack 530 meshes with all the gears 610. The movement of one rack 530 drives all the gears 610 to rotate synchronously. Alternatively, there can be multiple racks 530, and all multiple racks 530 are fixedly connected to the third mounting plate 540, and the racks 530 correspond one-to-one with the gears 610. As long as the above purpose can be achieved.

[0046] Based on the above, this application also provides a transfer device, including a drive unit 200 and a rotary bag-dropping device. The drive unit 200 can drive the fixed plate 100 to reciprocate above the first station 300 and the second station 400. The first station 300 can be, but is not limited to, a conveying station on the rear carriage ring. After the soft bag is filled and the tail is sealed in the rear carriage filling and sealing section, it is driven to the conveying station through the filling and sealing clamp for gripping and transfer by the air gripper 620. The second station 400 can be, but is not limited to, a bag-sorting ring conveyor belt. The air gripper 620 transfers the product to the bag-sorting ring conveyor belt for transport to the subsequent station.

[0047] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0048] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0049] This article uses specific examples to illustrate the principles and implementation methods of this utility model.
