Description

Technical Field

[0001] This invention relates to the field of pharmaceutical composite tube processing, and more specifically to a pharmaceutical composite tube processing equipment. Background Technology

[0002] Pharmaceutical composite tubes are widely used in the pharmaceutical packaging field. A pharmaceutical composite tube is a sleeve structure, which means that a larger diameter tube is placed on the outside of a smaller diameter tube to form a sleeve.

[0003] In existing technologies, the inner and outer tubes are typically placed separately in a guide mold, and then the inner tube is pressed into the outer tube using an extrusion process. This pressing method requires the inner and outer tubes to be placed into the mold separately from both ends. Before the pressing operation, the outer tube needs to be stacked in the mold, and after the pressing operation, the sleeve needs to be removed from the mold. Each pressing operation requires the removal and placement of the outer tube and sleeve. This removal and placement process takes considerable time, causing the pressing equipment to wait for these operations, thus limiting the overall efficiency of the pharmaceutical composite tube processing equipment.

[0004] Therefore, how to avoid slowing down the working efficiency of the pressing equipment due to the handling of outer tubes and sleeves is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a pharmaceutical composite tube processing equipment to solve the technical problem that the handling of the outer tube and sleeve slows down the working efficiency of the pressing equipment in the prior art.

[0006] To achieve the above-mentioned technical objectives, the technical solution of the present invention includes a pharmaceutical composite tube processing equipment, which comprises:

[0007] frame;

[0008] The nested component includes a buffer seat and a pressing member. The buffer seat is mounted on the frame and has a nesting hole. One end of the nesting hole is used to place an inner tube, and the other end is used to place an outer tube. The pressing member is installed at the end of the nesting hole where the inner tube is placed, and is used to press the inner tube into the outer tube.

[0009] The transport assembly includes a transport drive and a plurality of transport seats that clamp an outer tube. The transport seats slide relative to the frame and have a first position located at the end of the nested hole where the outer tube is placed, and a second position away from the buffer seat on the sliding trajectory of the transport seats. The transport drive is tractively connected to the plurality of transport seats to drive the plurality of transport seats to alternately enter the first position.

[0010] Preferably, there are two transport seats, which are slidably arranged on the same straight line and symmetrically arranged about the buffer seat.

[0011] Preferably, the conveying drive includes a linear motor with two drive ends, which are respectively connected to the two conveying seats.

[0012] Preferably, the conveying assembly further includes a feeding component, a discharging component, and a first clamping conveyor. The feeding component is used to introduce the outer tube, and the discharging component is used to discharge the sleeve. The first clamping conveyor includes a feeding gripper and a discharging gripper. The feeding gripper is used to grip and release the outer tube, and the feeding gripper moves between the feeding component and the second position. The discharging gripper is used to grip and release the sleeve, and the discharging gripper moves between the discharging component and the second position.

[0013] Preferably, the conveying assembly further includes a translation drive, which is tractively connected to the feed gripper and the discharge gripper to drive the feed gripper and the discharge gripper to translate synchronously. When the feed gripper is located at the feed member, the discharge gripper is located at the second position, and when the feed gripper is located at the second position, the discharge gripper is located at the discharge member.

[0014] Preferably, the feeding component includes a lifting seat, a lifting drive, a chuck, and a chuck drive. The lifting seat slides vertically relative to the frame. The lifting drive is connected to the lifting seat to drive the lifting seat to lift. The chuck is rotatably mounted on the lifting seat and has several slots for placing outer tubes. The chuck drive is connected to the chuck to drive the chuck to rotate and stop the chuck at any position on its rotation trajectory.

[0015] Preferably, the discharge component includes a conveyor belt, which is parallel to the sliding direction of the transport seat.

[0016] Preferably, the nested assembly further includes a buffer driver, the buffer seat is slidably disposed on the frame along the axial direction of the nesting hole, the buffer seat has a third position close to the pressing member and a fourth position away from the pressing member, and the buffer driver is tractively connected to the buffer seat to drive the buffer seat to switch between the third position and the fourth position.

[0017] Preferably, the frame includes a buffer guide rod, and the buffer seat has a buffer guide hole along its sliding direction. The buffer guide hole is sleeved on the buffer guide rod so that the buffer seat slides along the buffer guide rod. The pressing component includes a pressing seat and a pressing cylinder. The pressing seat has a pressing guide hole, and the pressing guide hole is sleeved on the buffer guide rod. The cylinder body of the pressing cylinder is mounted on the frame, and the piston rod of the pressing cylinder is connected to the pressing seat.

[0018] Preferably, the conveying assembly further includes a second clamping and conveying component, which includes an inner tube gripper and an inner tube drive component. The inner tube gripper is used to grip and release the inner tube, and the inner tube drive component is throttle-connected to the inner tube gripper to drive the inner tube gripper to move closer to or away from the end of the inner tube placed in the nesting hole.

[0019] Compared with the prior art, the beneficial effects of the present invention include: the transporter moves the unprocessed outer tube to one end of the nesting hole where the outer tube is placed; then the pressing component presses the inner tube, and the inner tube, guided by the nesting hole, nests into the outer tube to form a sleeve. The transporter holding the sleeve is then adjusted to a second position, moving it away from the buffer seat, ready to wait for the sleeve to be removed. By using a transport drive to alternately move each transporter to the first position, the end of the nesting hole where the outer tube is placed always has an outer tube waiting to be pressed in, shortening the waiting time for the nesting assembly to handle the outer tube and sleeve removal operations, and significantly improving the overall working efficiency of the pharmaceutical composite tube processing equipment.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] First, it should be noted that the terms "pipe," "inner tube," "outer tube," and "sleeve" appear frequently in this application. The inner tube has a smaller diameter, the outer tube has a larger diameter, and the inner tube is embedded within the outer tube to form the sleeve. "Pipe" is a general term encompassing the inner tube, outer tube, and sleeve. Furthermore, to facilitate the connection between the technical content described in this invention and actual production applications for those skilled in the art, the following example is provided: the inner tube is an LDPE pipe, the outer tube is a pharmaceutical packaging aluminum pipe, and the sleeve is a pharmaceutical packaging composite pipe formed by nesting an LDPE pipe and an aluminum pipe.

[0029] See also Figures 1 to 6 This invention provides a pharmaceutical composite tube processing equipment, belonging to the field of pipe processing. This equipment is used to press-fit inner and outer tubes together to form a sleeve. Using this equipment ensures that there is always an outer tube to be processed in the pressing position, shortening the waiting time for the sleeve pressing mechanism to handle the outer tube and sleeve placement operations, and significantly improving the overall working efficiency of the pharmaceutical composite tube processing equipment.

[0030] In some preferred embodiments, a pharmaceutical composite tube processing device includes a frame 100, a nesting assembly 200, and a transport assembly 300. The nesting assembly 200 includes a buffer seat 210 and a pressing member 220. The buffer seat 210 is mounted on the frame 100 and has a nesting hole 211. One end of the nesting hole 211 is used to place an inner tube, and the other end is used to place an outer tube. The pressing member 220 is installed at the end of the nesting hole 211 where the inner tube is placed, to press the inner tube into the outer tube. The transport assembly 300 includes a transport drive 310 and several transport seats 320 that hold the outer tube. The transport seats 320 slide relative to the frame 100, and their sliding trajectory includes a first position located at the end of the nesting hole 211 where the outer tube is placed, and a second position away from the buffer seat 210. The transport drive 310 is drive-connected to the several transport seats 320 to drive them to alternately enter the first position.

[0031] In the above embodiment, the transport seat 320 transports the unprocessed outer tube to the end of the nesting hole 211 where the outer tube is placed. Then, the pressing member 220 presses the inner tube, and the inner tube is nested into the outer tube under the guidance of the nesting hole 211 to form a sleeve. Subsequently, the transport seat 320 holding the sleeve is adjusted to the second position, so that the transport seat 320 is away from the buffer seat 210, and can wait for the sleeve to be removed. By using the transport drive member 310 to drive each transport seat 320 to alternately enter the first position, the end of the nesting hole 211 where the outer tube is placed always has an outer tube waiting to be pressed, which shortens the waiting time of the nesting assembly 200 for the outer tube and sleeve to be removed and placed, and greatly improves the overall working efficiency of the pharmaceutical composite tube processing equipment.

[0032] It is understandable that each transport seat 320 alternately reaches the first position, so that the outer tube carried by the transport seat 320 can sequentially reach the end where the outer tube of the nested tube is placed, and the sleeve can be transported away in time after the sleeve is processed, thereby moving the nested tube away from the buffer seat 210. Any implementation of the transport seat 320 that meets the above requirements is feasible, but in order to obtain ideal working efficiency, the specific number and sliding direction of the transport seats 320 still need to be reasonably planned.

[0033] Therefore, in some preferred embodiments, there are two transport seats 320, which are slidably arranged on the same straight line and symmetrically arranged about the buffer seat 210. Although more transport seats 320 can be arranged on the same plane, thereby further reducing the waiting time for the nested component 200 to wait for the outer tube and sleeve to be picked up and placed, considering the actual production situation, setting the sliding trajectory of the two transport seats 320 on the same straight line has the following advantages: transport equipment for the outer tube and sleeve can be reserved on both sides of the sliding trajectory of the transport seats 320.

[0034] Based on the above embodiments, any implementation of the transport drive 310 that can drive the two transport seats 320 to alternately enter the first position along a predetermined trajectory is feasible. For example, a cylinder or hydraulic cylinder can be used to drive the transport seats 320 to slide. See also Figures 1 to 2 In some preferred embodiments, the conveying drive 310 includes a linear motor 311, which has two drive ends, each of which is connected to a conveying seat 320. Since the pharmaceutical composite tube processing equipment of the present invention is a relatively complex mechanical device, the sliding speed and start / stop timing of each conveying seat 320 need to be coordinated with other related equipment. The linear motor 311 offers better controllability than cylinders and hydraulic cylinders, allowing operators to precisely control the sliding speed and start / stop timing of the conveying seats 320.

[0035] In some preferred embodiments, the conveying assembly 300 further includes a feed member 330, a discharge member 340, and a first clamping conveyor 350. The feed member 330 is used to introduce the outer tube, the discharge member 340 is used to discharge the sleeve, and the first clamping conveyor 350 includes a feed gripper 351 and a discharge gripper 352. The feed gripper 351 is used to grip and release the outer tube and moves between the feed member 330 and a second position. The discharge gripper 352 is used to grip and release the sleeve and moves between the discharge member 340 and a second position.

[0036] In the above embodiment, the feed member 330 is used to provide the outer tube to be processed, while the discharge member 340 is used to transport the processed sleeve. The feed gripper 351 can transport the outer tube provided by the feed member 330 and place it on the transport seat 320. The discharge gripper 352 can transport the sleeve on the transport seat 320 to the discharge member 340, thereby using the discharge member 340 to transport the processed sleeve.

[0037] Based on the above embodiments, the conveying assembly 300 further includes a translation drive 360, which is connected to the feed gripper 351 and the discharge gripper 352 to drive the feed gripper 351 and the discharge gripper 352 to translate synchronously. When the feed gripper 351 is located at the feed member 330, the discharge gripper 352 is located at the second position. When the feed gripper 351 is located at the second position, the discharge gripper 352 is located at the discharge member 340.

[0038] In the above embodiment, the feed gripper 351 and the discharge gripper 352 slide synchronously, so that when the feed gripper 351 grabs the outer tube on the feed member 330, the discharge gripper 352 grabs the sleeve on the transport seat 320. When the feed gripper 351 releases the outer tube on the transport seat 320, the discharge gripper 352 releases the sleeve on the discharge member 340. The synchronous operation of the feed gripper 351 and the discharge gripper 352 can quickly complete the operations of removing the sleeve from the transport seat 320 and stacking the outer tube on the transport seat 320. This shortens the time that the transport seat 320 stays at the second position, thereby improving the working efficiency of the transport seat 320.

[0039] It should be emphasized that the pharmaceutical composite tube processing equipment described in this invention includes three types of gripper mechanisms: an infeed gripper 351, an outfeed gripper 352, and an inner tube gripper 371. These gripper mechanisms are used to grip and release the tubes, serving the purpose of transporting the tubes. In the prior art, there are numerous embodiments of robotic arms and manipulators capable of transporting tubes. In principle, any gripper mechanism embodiment that can be installed on the pharmaceutical composite tube processing equipment described in this invention and meets the functional requirements defined by this invention is feasible.

[0040] Furthermore, the mechanical structures of the feed gripper 351, discharge gripper 352, and inner tube clamp 371 shown in the accompanying drawings are substantially the same, with only minor differences in specific dimensions. The structure of the feed gripper 351 is described in detail here to provide an illustrative explanation for those skilled in the art. See also... Figure 6 The feed gripper 351 includes a mounting base 3511, a gripper drive unit 3512, and two opposing clamping plates 3513. The clamping plates 3513 are slidably mounted on the mounting base 3511. The gripper drive unit 3512 drives the two clamping plates 3513 to move closer or further apart. When the two clamping plates 3513 are close together, they can clamp the pipe; when the two clamping plates 3513 are far apart, they can release the pipe. By moving the mounting base 3511 in space using an appropriate method, the grippers can move the pipe in space, achieving the purpose of pipe handling.

[0041] Based on the above embodiments, the clamping plate 3513 can be moved relative to the mounting base 3511 by means of guide rod and guide hole cooperation. Several clamping claw grooves for fitting the pipe can also be formed on the clamping plate 3513, thereby allowing the clamping plate 3513 to clamp the pipe more securely. The clamping claw drive unit 3512 can be a double-headed cylinder, with the cylinder body fixed to the mounting base 3511, and the two piston rods of the double-headed cylinder connected to the two clamping plates 3513 respectively, thereby driving the two clamping plates 3513 to move closer or further apart.

[0042] Typically, during the sleeve pressing process, the inner and outer tubes are placed vertically to avoid gravity interfering with their alignment. However, during long-distance transport of pipes on automated production lines, the pipes are usually stacked horizontally to lower their center of gravity and facilitate stable transport. Therefore, since the feeder 330 is used to provide the outer tube to the nested assembly 200, it needs to reverse the horizontally stacked outer tubes to make them vertically stacked.

[0043] Can participate Figure 5 In some preferred embodiments, the feed component 330 includes a lifting seat 331, a lifting drive component 332, a chuck 333, and a chuck drive component 334. The lifting seat 331 slides vertically relative to the frame 100. The lifting drive component 332 is connected to the lifting seat 331 to drive the lifting seat 331 to rise and fall. The chuck 333 is rotatably mounted on the lifting seat 331, and the chuck 333 has several slots for placing outer tubes. The chuck drive component 334 is connected to the chuck 333 to drive the chuck 333 to rotate and stop the chuck 333 at any position on its rotation trajectory.

[0044] In the above embodiment, the angle of the chuck 333 can be adjusted using the chuck drive 334, so that the slot can receive the horizontally placed outer tube. Subsequently, the angle of the chuck 333 can be adjusted again to change the placement direction of the outer tube in the slot, so that the outer tube changes from horizontal to vertical. At the same time, the height of the lifting seat 331 can be adjusted using the lifting drive 332, thereby changing the height of the outer tube, which is beneficial for the feed gripper 351 to grasp the outer tube.

[0045] In some preferred embodiments, the discharge unit 340 includes a conveyor belt 341 parallel to the sliding direction of the transport seat 320. The sleeve gripped by the discharge gripper 352 can be directly released onto the conveyor belt 341, thereby utilizing the conveyor belt 341 to transport the processed sleeve.

[0046] See also Figure 3 In some preferred embodiments, the nested assembly 200 further includes a buffer drive 230, and a buffer seat 210 is slidably disposed on the frame 100 along the axial direction of the nesting hole 211. The buffer seat 210 has a third position close to the pressing member 220 and a fourth position away from the pressing member 220. The buffer drive 230 is drively connected to the buffer seat 210 to drive the buffer seat 210 to switch between the third position and the fourth position.

[0047] In the above embodiment, the buffer seat 210 can be adjusted to the third position first, thereby freeing up space at the end of the nesting hole 211 where the outer tube is placed, allowing the transport seat 320 to smoothly carry the outer tube to the first position. Then, the buffer seat 210 can be adjusted to the fourth position, so that the outer tube is partially embedded in the nesting hole 211, while freeing up space at the end of the nesting hole 211 where the inner tube is placed, facilitating the insertion of the inner tube into the nesting hole 211. Subsequently, the pressing member 220 can press the inner tube, causing the inner and outer tubes to nest together under the guidance of the nesting hole 211. Since the buffer seat 210 can move between the third and fourth positions, space is sequentially freed up at both ends of the nesting hole 211, facilitating the placement of the inner and outer tubes respectively into the nesting hole 211. Compared to a fixed buffer seat 210 design, there is no need to reserve space at both ends of the buffer seat 210 simultaneously, thereby shortening the required installation height of the buffer seat 210 and reducing the overall size of the pharmaceutical composite tube processing equipment.

[0048] It is important to note here that the nesting hole 211 is used to guide the inner and outer tubes, thereby assisting in the press-fitting operation. Therefore, the inner wall of the nesting hole 211 needs to fit snugly against the inner and outer tubes. See also... Figure 4 Because the inner and outer tubes have different diameters, the diameter of the end of the nesting hole 211 where the inner tube is placed is smaller, and the diameter of the end of the nesting hole 211 where the outer tube is placed is larger. In addition, the axes of the end of the nesting hole 211 where the outer tube is placed and the end of the nesting hole 211 where the inner tube is placed need to be strictly aligned; otherwise, the inner and outer tubes cannot be nested together smoothly.

[0049] In some preferred embodiments, the frame 100 includes a buffer guide rod 110, and a buffer seat 210 has a buffer guide hole along its sliding direction. The buffer guide hole is sleeved on the buffer guide rod 110 so that the buffer seat 210 slides along the buffer guide rod 110. The pressing member 220 includes a pressing seat 221 and a pressing cylinder 222. The pressing seat 221 has a pressing guide hole, and the pressing guide hole is sleeved on the buffer guide rod 110. The cylinder body of the pressing cylinder 222 is installed on the frame 100, and the piston rod of the pressing cylinder 222 is connected to the pressing seat 221.

[0050] In the above embodiments, the inner and outer tubes need to be strictly aligned during the sleeve processing. Correspondingly, the nesting hole 211 also needs to be strictly aligned with the inner and outer tubes, allowing the buffer seat 210 to slide along the buffer guide rod 110, ensuring the buffer seat 210 has a precise sliding trajectory. The pressing cylinder 222 can drive the pressing seat 221, thereby completing the pressing of the sleeve.

[0051] In some preferred embodiments, the transport assembly 300 further includes a second clamping and conveying member 370, which includes an inner tube gripper 371 and an inner tube drive member 372. The inner tube gripper 371 is used to grip and release the inner tube, and the inner tube drive member 372 is kinetically connected to the inner tube gripper 371 to drive the inner tube gripper 371 to move closer to or away from the end of the inner tube placed in the nesting hole 211.

[0052] The feeding gripper 351 and the discharging gripper 352 slide synchronously, so that when the feeding gripper 351 grabs the outer tube on the feeding component 330, the discharging gripper 352 grabs the sleeve on the transport seat 320. When the feeding gripper 351 releases the outer tube on the transport seat 320, the discharging gripper 352 releases the sleeve on the discharging component 340. This shortens the dwell time of the transport seat 320 at the second position, thereby improving the working efficiency of the transport seat 320. When the transport seat 320 carrying the outer tube approaches the buffer seat 210, the buffer seat 210 is in the third position close to the pressing component 220, so that the transport seat 320 carrying the outer tube can smoothly reach the first position. Then the buffer seat 210 can be adjusted to the fourth position, so that the outer tube is partially embedded in the nesting hole 211. At the same time, space can be made at the end of the nesting hole 211 where the inner tube is placed, and the inner tube is placed at the end of the nesting hole 211 using the inner tube clamp 371. Subsequently, the pressing component 220 presses down on the inner tube, which, guided by the nesting hole 211, nests into the outer tube to form a sleeve. The transport seat 320 holding the sleeve is then adjusted to the second position, moving it away from the buffer seat 210, ready to await the removal of the sleeve. The transport drive component 310 drives each transport seat 320 to alternately enter the first position, ensuring that the end of the nesting hole 211 where the outer tube is placed always has an outer tube awaiting pressing, shortening the waiting time for the nesting assembly 200 to handle the removal and placement of the outer tube and sleeve, and significantly improving the overall working efficiency of the pharmaceutical composite tube processing equipment.

[0053] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
