Description

Technical Field

[0001] The invention belongs to the technical field of pharmaceutical equipment, and in particular relates to a guiding device for a container with a lip. Background Art

[0002] In drug containers, such as Figure 7 The prefilled needle shown belongs to a container with a lip. In some pharmaceutical equipment, in order to meet process requirements, the container with a lip is placed vertically in a placement seat. Since the container has a lip, there is a problem of difficulty in aligning the container and causing it to get stuck when the container is placed vertically in the placement seat.

[0003] For example, in the automatic assembly equipment for prefilled needle injection pens, since the prefilled needle needs to be turned when loading, if the angle of the prefilled needle flange is abnormal with the assembly direction, it will cause the subsequent pre-installed flange to be damaged, resulting in product scrapping, affecting the assembly qualification rate and affecting production. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a guiding device for a container with a lip which has a reasonable layout and can realize automatic deviation correction.

After the container with the lip is placed on the placement seat, the spiral inclined surface is used to make the lip face in a consistent direction. The layout is reasonable. When the container is placed vertically in the placement seat, the lip rotates along the spiral inclined surface under the action of gravity, so that the lip face of the container is in a consistent direction after being placed in place, thereby realizing automatic correction.

[0007] As a further improvement of the above technical solution:

[0008] It also includes a driving mechanism, which is connected to the placement seat and is used to drive the placement seat to rotate. The direction in which the spiral slope spirals from the low point of the spiral to the high point of the spiral is the same as the rotation direction of the placement seat. When the placement seat rotates, the container is driven to rotate relative to the placement seat, thereby further ensuring the correction effect.

[0009] Guide parts are provided on both sides of the entrance of the accommodating cavity. The spiral inclined surfaces are centrally symmetrically arranged on both sides of the entrance of the accommodating cavity. An accommodating part is provided between the guide parts, which is suitable for guiding the pre-filled needle.

[0010] At least four grooves are provided on the placement seat, and a detection component is provided on one side of the placement seat. The detection component includes a photoelectric transmitting and receiving mechanism and a photoelectric reflector. After the driving mechanism drives the placement seat into position and the placement seat is empty, the photoelectric detection passes through the groove. Abnormal container placement can be detected and alarmed by the sensor, thereby effectively reducing the defective rate.

[0011] It includes multiple groups of placement seats, each of which has a gear at the bottom. The gears of the multiple groups of placement seats are connected to the same rack, which is connected to a driving mechanism, and can realize the reversal of multiple products at the same time.

[0012] It also includes a mounting plate, the placement seat passes through the mounting plate and is connected to a driving mechanism arranged below the mounting plate, the placement seat is provided with a dust cover, the dust cover is arranged above the mounting plate, and a detection component is also installed on the mounting plate to achieve dust protection.

[0013] A first connecting shaft is provided at the bottom of the placement seat, a bearing and a spacer sleeve are provided on the first connecting shaft, the side of the first connecting shaft is connected to the gear through a flat key, and a locking piece is provided at the end of the first connecting shaft. The bearing is installed on the support frame to support the rotation action, reduce friction, and ensure rotation accuracy.

[0014] A slide rail is provided under the mounting plate, and a slider is slidably connected to the slide rail. One side of the slider is connected to the output end of the driving mechanism through a flange, and the other side of the slider is connected to the rack. When the slider moves on the slide rail, it drives the rack to move, ensuring smooth and stable movement.

[0015] Limiting members are provided at both ends of the mounting plate, and the limiting members are used to limit the position of the slider. The limiting members include adjusting members with buffer pads, which can adjust the stroke to ensure that the stroke does not exceed the preset range to avoid damage to the equipment.

[0016] A second connecting shaft is provided at the bottom of the placement seat, the upper end of the first connecting shaft is an arc block, the other end of the arc block is connected to the clamping block, the second connecting shaft is inserted between the arc block and the clamping block, the clamping block and the arc block are detachably connected, and the clamping block is used to clamp the first connecting shaft and the second connecting shaft, which is convenient for disassembly and assembly of the placement seat.

DETAILED DESCRIPTION

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 7 The illustrated container with a lip, namely a prefilling needle 27, includes lips 28 symmetrically arranged on either side and flanges 29 symmetrically arranged on either side of the lips 28. The lips 28 are curved, and the flanges 29 are linear. The guiding device for a lipped container of the present application is applicable to prefilling needles 27 as well as other shaped bottles, such as bottles with three or more sets of lips 28, wherein the lips 28 are curved and connected by flanges 29. When the shaped bottle or prefilling needle 27 is placed vertically in a storage seat, the lips 28 are guided to automatically correct deviation.

[0029] like Figures 1 to 6 As shown, a guiding device for a container with a lip includes a placement seat 2, a receiving cavity 3 is provided in the middle of the placement seat 2, a guide portion 4 is provided at the entrance of the receiving cavity 3, the guide portion 4 includes a spiral bevel 5, and the spiral bevel 5 is rotationally symmetrically arranged on the entrance side of the receiving cavity 3. After the container with a lip is placed on the placement seat 2, the spiral bevel 5 is used to make the lip face consistent in direction.

[0030] The guide portion 4 is arranged at the entrance of the accommodating chamber 3 and has a reasonable layout. When the container is placed vertically into the accommodating chamber 3 of the placement seat 2, when the direction of the container deviates, the lip will contact the spiral slope 5, wherein the rotation center of the spiral slope 5 is the central axis of the accommodating chamber 3. Under the action of gravity, the lip slides along the spiral slope 5, and the container can be rotated in the accommodating chamber 3, so that the lip of the container is in the same direction after being placed in place, thereby realizing automatic correction.

[0031] It also includes a driving mechanism 1, which is connected to the placement seat 2 and is used to drive the placement seat 2 to rotate. The direction in which the spiral slope 5 spirals from the lowest point to the highest point is the same as the rotation direction of the placement seat 2.

[0032] In the prefilled needle pen assembly system, a first manipulator places the prefilled needle into a holder 2. A drive mechanism 1 then rotates the holder 2, and a second manipulator transfers the prefilled needle from the holder 2 to the pen barrel. Assembly is completed at subsequent workstations. To accommodate a variety of specifications and meet the requirements for incoming prefilled needles and the assembly of different pen barrels, for example, the engagement position of Type A prefilled needle pen differs from that of Type B. A rotatable holder 2 is provided to adjust the relative position of the prefilled needle and the pen barrel. For example, when placing Type A prefilled needle in the holder, the holder 2 does not need to rotate. However, when placing Type B prefilled needle, the holder 2 rotates 90 degrees.

[0033] While meeting the reversing function required by the equipment, since the placement seat 2 rotates, and the direction in which the spiral bevel 5 rotates from the low point of the spiral to the high point of the spiral is the same as the rotation direction of the placement seat 2, when the placement seat 2 rotates and reverses, it is equivalent to the spiral bevel 5 rotating from the low point to the high point. Under the action of friction, the lip 28 of the prefilled needle 27 rotates from the high point to the low point of the spiral bevel 5, and the correction is completed at the same time as the reversal. Compared with the effect of gravity, the friction force during reversal is more stable. When the deflection angle between the container and the placement seat 2 is too large, relying solely on gravity may cause the container to be stuck on the spiral bevel 5. By rotating the placement seat 2, the correction effect can be better guaranteed, and the correction can be completed quickly. The prefilled needle 27 can slide off quickly, meeting the time rhythm required for the previous and next processes when assembling the prefilled needle injection pen.

[0034] Guide parts 4 are provided on both sides of the entrance of the accommodating chamber 3, and spiral bevels 5 are arranged on both sides of the entrance of the accommodating chamber 3 in a centrally symmetrical manner. An accommodating part 6 is provided between the guide parts 4. The separately arranged guide part 4 and the spiral bevel 5 arranged on the guide part 4 in a centrally symmetrical manner are used to guide the lip 28 of the pre-filled needle 27. The accommodating part 6 is used to accommodate the lip 28 after it is in place, ensuring that the pre-filled needle 27 can be hung on the accommodating part 6 to avoid damage to the needle head at the bottom of the pre-filled needle, and adapting to the shape and structure of the pre-filled needle 27.

[0035] It also includes a mounting plate 13, the placement seat 2 passes through the mounting plate 13 and is connected to the driving mechanism 1 arranged below the mounting plate 13, a dust cover 14 is provided on the placement seat 2, and the dust cover 14 is arranged above the mounting plate 13 to achieve dustproof and protection, and a detection component is also installed on the mounting plate 13, at least two grooves 7 are provided on the placement seat 2, and a detection component is provided on one side of the placement seat 2, and the detection component includes a detection photoelectric transmitting and receiving mechanism 8 and a photoelectric reflector 9. After the driving mechanism 1 drives the placement seat 2 into place and the placement seat 2 is empty, the photoelectric detection passes through the groove 7.

[0036] The detection photoelectric signal is emitted by the photoelectric transmitting and receiving mechanism 8. When there is no container in the placement seat 2, the photoelectric signal passes through the groove 7 and the placement seat 2 to the photoelectric reflector 9. Then the detection photoelectric signal is reflected by the photoelectric reflector 9 and received by the detection photoelectric transmitting and receiving mechanism 8. At this time, it can be judged that there is no container in the placement seat 2. Before the container needs to be placed in the placement seat 2, the detection signal can be used to determine that there are no containers remaining in the placement seat 2 to ensure that the previous batch of containers have been removed. If not, a shutdown alarm will be issued to prevent collision and improve equipment stability.

[0037] Four grooves 7 can be provided on the placement seat 2, and the grooves can be symmetrically arranged according to the rotation angle of the placement seat 2. When the placement seat 2 rotates and resets, the detection photoelectric sensor can detect the storage status in the accommodating cavity 3 through the grooves 7, ensuring stable operation of the equipment. Multiple groups of placement seats 2 are provided with grooves 7, and the positions of the grooves 7 are distributed along a straight line. The detection photoelectric sensor can pass through the grooves 7 of multiple placement seats 2. When there is no container in each placement seat 2, the detection photoelectric sensor can smoothly complete the reflection process. If there is a residual container in any placement seat 2, an alarm will be issued, notifying manual processing. The detection of the presence of containers in multiple placement seats 2 can be completed by a single detection component.

[0038] The device comprises multiple sets of placement seats 2, each with a gear 10 at its base. Each gear 10 in each set of placement seats 2 is connected to a common rack 11, which is in turn connected to a drive mechanism 1. A first connecting shaft 15 is provided at the base of each placement seat 2. A bearing 16 and a spacer 17 are sleeved on the first connecting shaft 15. The side of the first connecting shaft 15 is connected to the gear 10 via a flat key 18. A locking member 20 is provided at the end of the first connecting shaft 15. The bearing 16 is mounted on a support frame 21. A slide rail 22 is provided below the mounting plate 13. A slider 23 is slidably connected to the slide rail 22. One side of the slider 23 is connected to the output end of the drive mechanism 1 via a flange 24. The other side of the slider 23 is connected to the rack 11. As the slider 23 moves on the slide rail 22, it drives the rack 11, reducing motion resistance, improving motion accuracy, and preventing offset. Driven by the rack 11, the gears 10 rotate synchronously, thereby driving the placement seats 2 to rotate synchronously, achieving reversal of the prefilled needle. The device has a compact structure, takes up little space, and operates stably and reliably.

[0039] A limiter 25 is provided on the mounting plate 13. The limiter 25 is used to limit the position of the slider 23. The limiter 25 includes an adjusting member with a buffer pad. The adjusting member is a screw. The screw can be screwed on the mounting plate 13 to adjust the position. A buffer pad is provided on the side of the screw close to the slider 23 to achieve noise reduction and avoid damage to the equipment. By adjusting the position of the screw, the sliding position of the slider 23 can be limited, thereby realizing the adjustment of the rotation angle of the placement seat 2.

[0040] A second connecting shaft 26 is provided at the bottom of the placement seat 2. The upper end of the first connecting shaft 15 is an arcuate block 19, the other end of which is connected to the clamping block 12. The second connecting shaft 26 is inserted between the arcuate block 19 and the clamping block 12. The clamping block 12 and the arcuate block 19 are detachably connected, and the clamping block 12 is used to clamp the first connecting shaft 15 and the second connecting shaft 26. By disassembling and assembling the clamping block 12, the placement seat 2 can be quickly assembled and disassembled, facilitating adjustment of the position of the placement seat 2, such as adjusting the angle of the placement seat 2 and replacing the placement seat 2 according to different specifications.
