Description

Technical Field

[0001] The utility model belongs to the technical field of pharmaceutical equipment, and in particular relates to an empty capsule shell rejecting and collecting device. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] In the production process of capsule drugs, the prepared capsules have unqualified filling amount or empty particles and need to be rejected. However, since it is not easy to see the internal medicine amount of the prepared capsules, manual inspection cannot accurately judge the quality of the capsules by naked eyes. Manual rejection is quite difficult and the workload is huge. At present, the aluminum-plastic capsule packaging equipment on the market has its own empty capsule inspection and rejection device. When rejecting the empty capsules on the medicine plate, it will also reject the qualified capsules in the same row. It cannot accurately identify and reject the complete empty capsule shells, making it impossible to guarantee the capsule yield rate.

[0004] A mechanism for rejecting empty shell capsules proposed in accordance with the Chinese invention patent (application number 201810372917.2) comprises a feed chute with a flat bottom wall arranged at an angle, a baffle plate provided at the high end of the feed chute, the baffle plate isolating the feed hopper at the high end of the feed chute, a queue opening is formed between the baffle plate and the bottom wall of the feed chute, a hollow section is provided in the middle of the feed chute, a conveyor belt is provided in the hollow section, a wind tunnel is docked at the low end of the feed chute, a medicated capsule output channel is docked at the end of the wind tunnel away from the feed chute, an empty shell capsule output channel is provided above the medicated capsule output channel, and the wind tunnel is used to blow the empty shell capsules up to align with the empty shell capsule channel so that the empty shell capsules can enter the empty shell capsule channel under the action of inertia. The above-mentioned method of blowing out the empty shell capsules before molding also has certain technical problems, namely, it is easy to cause the empty shell capsules to fly around and collide during the blowing process, causing the capsules to split, and at the same time, secondary damage is caused to the filled capsules, resulting in secondary defects.

[0021] 4. The utility model is provided with a pressure reducing valve to adjust the suction force, so that different suction forces can be provided for capsules of different numbers, sizes and weights during the suction and rejection process, thereby improving the applicability of the device.

DETAILED DESCRIPTION

[0029] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0030] Example 1

[0031] In a typical implementation of the present invention, Figure 1 As shown, a device for collecting and rejecting empty capsule shells is provided, including a vibration plate 11, the vibration plate 11 contains capsules 2 to be inspected, and a suction nozzle 3 is provided above the vibration plate 11. The suction nozzle 3 can be fixed above the vibration plate 11, or can be placed above the vibration plate 11 in other ways according to actual application conditions, as long as the suction of the capsule can be achieved. The other end of the suction nozzle 3 opposite to the vibration plate 11 is connected to a conveying pipe 4, and the other end of the conveying pipe 4 opposite to the suction nozzle 3 is connected to a vacuum suction mechanism 12, and the other end of the vacuum suction mechanism 12 is connected to a collection bag 8 through a conveying pipe, and the collection bag 8 is used to collect and hold empty capsule shells 9.

[0032] It is understandable that, during the connection process of the above structure, the sealing of the connection is ensured to prevent the device from leaking and thus affecting the absorption effect of the capsule.

[0033] The vibration plate 11 is set as a cylindrical structure, and a raised annular baffle 1 is provided at the top of the vibration plate 11 along the circumferential edge, and a boss 10 coaxial with the vibration plate 11 is provided in the middle of the vibration plate 11. The boss 10 is a conical boss, and the top of the boss 10 is a plane. The bottom edge of the boss 10 and the annular baffle 1 form an annular containing surface at the top of the vibration plate 11. The annular containing surface is a horizontal surface for containing the capsules 2 to be tested. The capsules can be placed on the vibration plate 11 by manual or other production line transportation methods, and stored in a flat form, so as to facilitate the suction of the capsules by the suction nozzle 3.

[0034] like Figure 2As shown, the suction nozzle 3 is configured as a trapezoidal flat structure, including a suction nozzle front end 31 and a suction nozzle rear end 32. The suction nozzle front end 31 is a flat structure, and the suction nozzle rear end 32 is a cylindrical structure connected to the conveying pipe; the width of the suction nozzle front end 31 is greater than the width of the suction nozzle rear end 32. In addition, the width of the suction nozzle front end 31 is consistent with the width of the annular containing surface, and the suction nozzle front end 31 is placed parallel to the annular containing surface. With such a configuration, the structure of the suction nozzle front end 31 is convenient for sucking the empty shell capsules 9, and the structure of the suction nozzle rear end 32 is convenient for collecting the sucked empty shell capsules 9 and conveying them through the connected conveying pipe 4. With such a configuration, when the vibration plate 11 rotates, the suction nozzle 3 can fully suck and remove the capsules 2 to be detected in the annular containing surface, thereby ensuring the yield rate of the capsules.

[0035] In addition, the delivery tube 4 is a hose made of a flexible material, which enables the device to be easily placed and used in different application environments.

[0036] In the present utility model, the vacuum material suction mechanism 12 includes a vacuum generator 5, a pressure reducing valve 5, and a pressure reducing valve 7. Figure 3 As shown, the vacuum generator includes a feed port 51, a discharge port 52, and a compressed air inlet 53. The feed port 51 is connected to a delivery pipe 4 connected to one end of a suction nozzle 3, the discharge port 52 is connected to a delivery pipe 4 connected to one end of a collection bag 8, and the compressed air inlet 53 is connected to a pressure reducing valve 6. Furthermore, the pressure reducing valve 7 and the pressure reducing valve 6 are arranged in the same gas branch, so that the pressure reducing valve can be opened and closed.

[0037] With such arrangement, the pressure reducing valve 6 can adjust the suction force, thereby providing different suction forces for capsules of different numbers, sizes and weights during the suction and rejection process, thereby improving the applicability of the device.

[0038] At the same time, the collecting bag 8 is made of a breathable material, so that the empty shell capsules 9 can be collected and the gas can flow smoothly through the collecting bag 8 during the collection process, avoiding gas blockage in the conveying pipe 4 caused by the collection bag 8 being not ventilated, which affects the operation of the device. One end of the collecting bag 8 connected to the conveying pipe 4 is detachably connected. When the collecting bag 8 collects a certain number of empty shell capsules 9, it can be replaced.

[0039] The working process of the empty capsule shell removal and collection device provided by the utility model is as follows:

[0040] The capsule to be tested is spread flat on the annular containing surface of the vibration plate, and the suction nozzle is placed above the capsule to be tested to facilitate the suction of the capsule. The vacuum suction mechanism is started, and the compressed air switch of the vacuum generator is turned on. Compressed air is introduced into the compressed air inlet. The vacuum generator generates negative pressure and thus suction, so that the suction nozzle sucks the capsule to be tested. The empty capsule shell is light in weight and is sucked into the conveying pipe through the suction nozzle, and enters the collection bag through the vacuum generator, completing the suction and removal of incomplete capsule shells and empty capsule shells in the capsule to be tested, as well as the collection of incomplete capsule shells and empty capsule shells. The pressure reducing valve can adjust the suction force, and the pressure reducing valve can open and close the pressure reducing valve.

[0041] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
