Description

Technical Field

[0001] This invention relates to the field of capsule blister packaging machine technology, specifically a capsule turning device. Background Technology

[0002] Currently, filled capsules are generally loaded into pre-formed blister packs using blister packaging machines. The blister packs are then heat-sealed and punched to form blister panels. Since the filled capsules are scattered, they need to be aligned and their orientations made consistent before being loaded into the blister packs. Existing technologies use capsule turning devices to achieve this function. However, existing capsule turning devices have complex structures, are time-consuming and labor-intensive to manufacture and maintain, and are costly. Summary of the Invention

[0003] The purpose of this invention is to provide a capsule turning device to solve the problems in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a capsule turning device, comprising a feeding roller 2 and a feeding plate 3, wherein the feeding plate 3 is provided with a slide rail 301, and the feeding roller 2 is provided with a capsule slot 201 corresponding to and cooperating with the slide rail 301; and further comprising a fixed turning roller 1, wherein the feeding roller 2 is rotatably sleeved on the outer circumference of the turning roller 1, and a groove 101 is provided on the outer circumference of the turning roller 1 below the outlet of the slide rail 301; depending on the rotation direction of the feeding roller 2, the end of the groove 101 extends out of the turning roller 1. The outer circular surface of roller 1, the first end of the groove 101 is located below the outlet of the slide 301, and a notch 302 is opened on the left side of the lower end of the slide 301. The rotation direction of the feeding roller 2 is counterclockwise. The width of the groove 101 is greater than the diameter of the capsule body of the capsule 16 and smaller than the diameter of the capsule cap. The capsule slot 201 is clearance-fitted with the maximum enveloping solid of the capsule 16. When the capsule 16 passes through the capsule slot 201 and the lower end of the capsule cap abuts against the edge of the groove 101, the top of the capsule body of the capsule 16 contacts the lower edge of the notch 302.

[0005] Furthermore, one end of the feeding roller 2 is connected to a power device to drive the feeding roller 2 to rotate along its own axis, and the power device includes at least a servo motor 5.

[0006] Furthermore, the power unit also includes a motor mount 7 for mounting the servo motor 5, a reducer 6 disposed between the servo motor 5 and the unloading roller 2, and a lifting adjustment device 8 for adjusting the vertical position of the motor mount 7. The lifting adjustment device 8 includes a worm gear reducer mounted on a base plate 9. The output shaft of the worm gear 801 of the worm gear reducer is threaded and engages with the motor mount 7. When the worm 802 of the worm gear reducer is powered, the output shaft of the worm gear 801 drives the motor mount 7 to move up and down. A movable adjustment seat 10 is mounted on one end of the base plate 9 away from the motor mount 7. A screw 12 is screwed onto the movable adjustment seat 10. The screw 12 is rotatably supported by a fixed adjustment seat 11.

[0007] Furthermore, a blister guide plate 17 is provided below the feeding roller 2, and a medicine baffle plate 15 is provided on the outer circular surface of the feeding roller 2 between the notch 302 and the blister guide plate 17. The inner wall of the medicine baffle plate 15 is an arc shape adapted to the outer circular surface of the feeding roller 2.

[0008] Furthermore, the capsule turning device also includes a bracket 14 with an adjustment groove 1401, and fasteners are connected to the outer end of the turning roller 1 through the adjustment groove 1401.

[0009] Furthermore, the groove 101 is horizontally positioned.

[0010] Furthermore, the end of the groove 101 is higher than the beginning end.

[0011] The working principle and beneficial effects of this invention: The capsule turning device provided by this invention has a feeding roller rotatably sleeved on the outer circle of a turning fixed roller. A groove is provided on the outer circle of the turning fixed roller below the slide outlet. Depending on the rotation direction of the feeding roller, the end of the groove extends beyond the outer circle of the turning fixed roller, the beginning of the groove is located below the slide outlet, and a notch is opened on the front side of the lower end of the slide. The width of the groove is greater than the diameter of the capsule body but smaller than the diameter of the capsule cap. Thus, when capsules with inconsistent orientations enter the capsule slot through the slide, if the capsule body is facing down, because the width of the groove is greater than the diameter of the capsule body but smaller than the diameter of the capsule cap, the lower end of the capsule body enters the groove. As the feeding roller rotates, the capsules on it... The rear wall of the slot pushes the capsule cap forward, causing it to tilt in the direction of rotation of the feeding roller, thus creating a forward-facing capsule cap position. As the feeding roller continues to rotate, the capsule cap is pushed out of the groove and moves forward within the capsule slot. If the capsule cap enters the capsule slot downwards, because the width of the groove is smaller than the diameter of the capsule cap, the capsule cap is located on the edge of the groove and cannot enter the groove. The top of the capsule body is blocked by contact with the lower edge of the notch. As the feeding roller rotates, the rear wall of the capsule slot pushes the capsule cap forward, causing the capsule body to tilt backwards and slide into the capsule slot, thus creating a forward-facing capsule cap position. This automatically completes the capsule reversal process, which has the advantages of fewer parts, simple structure, and high reliability. Attached Figure Description

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] Please see Figure 1-4A capsule turning device includes a feeding roller 2, a feeding plate 3, a slide rail 301 on the feeding plate 3, a vibrating feeder 4 for supplying capsules to the slide rail 301, and a frame 13 supporting the vibrating feeder 4. The feeding roller 2 has capsule slots 201 that correspond to the slide rail 301. It also includes a fixed turning roller 1. The feeding roller 2 is rotatably mounted on the outer circumference of the turning roller 1. A groove 101 is provided on the outer circumference of the turning roller 1 below the outlet of the slide rail 301. Depending on the rotation direction of the feeding roller 2, the groove... The outer circular surface of the turning roller 1 extends from the end of 101; the first end of the groove 101 is located below the outlet of the slide 301; a notch 302 is opened on the left side of the lower end of the slide 301; the rotation direction of the feeding roller 2 is counterclockwise; the width of the groove 101 is greater than the diameter of the capsule body of the capsule 16 and smaller than the diameter of the capsule cap; the capsule slot 201 is clearance-fitted with the maximum enveloping solid of the capsule 16; when the capsule 16 passes through the capsule slot 201 and the lower end of the capsule cap abuts against the edge of the groove 101, the top of the capsule body of the capsule 16 contacts the lower edge of the notch 302; With the above settings, when capsules with inconsistent orientations enter the capsule slot 201 through the slide 301, if the capsule body is facing down, since the width of the groove 101 is greater than the diameter of the capsule body of the capsule 16 and less than the diameter of the capsule cap, the lower end of the capsule body enters the groove 101. As the feeding roller 2 rotates, the rear wall of the capsule slot 201 pushes the capsule cap so that the capsule cap tilts forward in the direction of rotation of the feeding roller 2, thus forming a state where the capsule cap faces forward. As the feeding roller 2 continues to rotate, the capsule cap is pushed out of the groove 101 and moves forward in the capsule slot 201. If the capsule cap enters the capsule slot 201 with the cap facing down, the width of the groove 101 is smaller than the diameter of the capsule cap. At this time, the capsule cap is located on the edge of the groove 101 and cannot enter the groove 101. The top of the capsule body is blocked by the lower edge of the notch 302. As the feeding roller 2 rotates, the rear wall of the capsule slot 201 pushes the capsule cap forward, causing the capsule body to fall backward and slide into the capsule slot 201, forming a state where the capsule cap faces forward. In this way, the reversal of the capsule 16 is automatically completed, which has the advantages of fewer parts, simple structure, and high reliability.

[0015] Preferably, one end of the feeding roller 2 is connected to a power unit to drive the feeding roller 2 to rotate along its own axis. The power unit includes at least a servo motor 5, and further includes a motor mount 7 for mounting the servo motor 5, a reducer 6 located between the servo motor 5 and the feeding roller 2, and a lifting adjustment device 8 for adjusting the vertical position of the motor mount 7. Typically, the motor mount 7 is slidably connected to the base plate 9 via a vertically arranged linear guide or guide post and guide sleeve structure. The lifting adjustment device 8 includes a worm gear reducer mounted on the base plate 9. The output shaft of the worm gear 801 of the worm gear reducer is threaded and engages with the motor mount 7. When the worm 802 of the worm gear reducer outputs... When power is applied, the output shaft of the worm gear 801 drives the motor base 7 to move up and down. A movable adjustment seat 10 is installed at the end of the base plate 9 away from the motor base 7. A screw 12 is screwed onto the movable adjustment seat 10. The screw 12 is rotated and supported by a fixed adjustment seat 11. The fixed adjustment seat 11 is installed at the bottom of the frame 13 by fasteners. In this embodiment, the screw 12 is aligned with the axis of the feeding roller 2. It can be understood that the screw 12 can also be set to be perpendicular to the axis of the feeding roller 2. It can be set according to the specific structure to facilitate the adjustment of the position of the motor base 7, thereby adjusting the fit between the feeding roller 2 and other components. The operation is simple and the positioning is accurate.

[0016] Preferably, a blister guide plate 17 is provided below the feeding roller 2, and a baffle plate 15 is provided between the notch 302 and the blister guide plate 17 on the outer circular surface of the feeding roller 2. The inner wall of the baffle plate 15 is an arc shape that matches the outer circular surface of the feeding roller 2. In this way, during operation, the formed blister is guided by the blister guide plate 17 to the bottom of the feeding roller 2. The capsule 16 reaches the top of the blister along the inner surface of the baffle plate 15 and the outer surface of the turning roller 1 in the capsule slot 201, and falls into the blister from the capsule slot 201. In this way, it is ensured that the capsule 16 will not fall out of the capsule slot 201 during the process of transferring from the exit position of the slide 301 to the blister, thus ensuring the reliability of the device.

[0017] In a further preferred embodiment, the capsule turning device also includes a bracket 14 with an adjustment groove 1401. The fastener is connected to the outer end of the turning roller 1 through the adjustment groove 1401, so as to facilitate the adjustment of the position of the turning roller 1 so that it has a good fit with the feeding roller 2.

[0018] In a further preferred embodiment, the groove 101 is horizontally arranged. Thus, when the capsule 16 enters the groove 101 with the capsule body facing downward, there is a suitable frictional resistance between the end of the capsule body and the groove 101. This ensures that as the feeding roller 2 rotates, the rear wall of the capsule slot 201 pushes the capsule cap forward, causing the capsule cap to tilt in the direction of rotation of the feeding roller 2, thereby forming a state where the capsule cap faces forward.

[0019] In a further preferred embodiment, the end of the groove 101 is higher than the beginning end to provide greater frictional resistance between the end of the capsule body and the groove 101. This ensures that as the feeding roller 2 rotates, the rear wall of the capsule slot 201 pushes the capsule cap forward in the direction of rotation of the feeding roller 2, thereby forming a state in which the capsule cap faces forward.
