Description

Technical Field

[0001] The present application relates to the technical field of hollow capsule screening equipment, and in particular to a hollow capsule waste rejection equipment. Background Art

[0002] Capsules are widely used in the field of modern medicine. Filling drugs into capsules can protect the drug properties from being destroyed on the one hand, and protect the digestive organs and respiratory tract on the other hand.

[0003] After the drug filling process is completed, the hollow capsules need to be sorted and removed so that they can be recycled and prevented from flowing into subsequent work sections, causing a waste of work time and affecting production efficiency.

[0004] Currently, when removing hollow capsules, the capsules are placed on a backlight board, and the operator observes the light transmittance of the capsules to determine whether they are hollow capsules. On the one hand, there are cases of mis-picking and missed picking, and on the other hand, the operator works in front of the backlight board for a long time, which is prone to cause various eye diseases. Utility Model Content

[0005] In order to automatically remove the hollow capsules, the present application provides a hollow capsule rejection device.

[0006] The present application provides a hollow capsule waste rejection device, which adopts the following technical solution:

[0007] A hollow capsule rejection device comprises a frame, a feeding box, a conveying assembly, a rejection assembly and a detection assembly; the feeding box is fixedly arranged on the frame, and a discharge port is opened at the bottom of the feeding box; the conveying assembly comprises a first conveyor belt, a first conveyor pulley and a motor; the first conveyor belt is arranged on the frame; two first conveyor pulleys are arranged, the first conveyor pulleys are rotatably connected with the frame, and the first conveyor belt is wound around the two first conveyor pulleys; the motor is arranged on the frame, and the motor is used to drive the first conveyor pulley to rotate; the rejection assembly is arranged on the frame and is used to reject hollow capsules; the detection assembly is arranged on the frame and is used to detect capsules on the first conveyor belt and control the working state of the rejection assembly.

[0008] By adopting the above technical solution, when the hollow capsules are rejected, the operator pours the capsules into the feeding box, and the capsules flow out from the discharge port under the action of their own gravity. The motor drives the first conveyor belt wheel to rotate, thereby driving the first conveyor belt to rotate, and the outflowing capsules fall on the first conveyor belt for transmission. During the transmission process, the capsules are detected by the detection component, and the hollow capsules and qualified capsules in the capsules are distinguished, and then the hollow capsules are rejected by the rejection component. The automated rejection of hollow capsules is realized, which not only saves manpower, but also improves the rejection accuracy of hollow capsules.

[0009] Optionally, the rejection assembly includes a push plate and an electric telescopic rod; the push plate is arranged on the top of the first conveyor belt; the fixed end of the electric telescopic rod is fixedly arranged on the frame, and the movable end of the electric telescopic rod is fixedly connected to the push plate.

[0010] By adopting the above technical solution, when the hollow capsules are removed, the electric telescopic rod is extended to drive the push plate to move. During the movement of the push plate, the hollow capsules on the first conveyor belt are pushed away from the first conveyor belt, thereby realizing the removal of the empty capsules.

[0011] Optionally, the detection component includes a laser transmitter, a laser receiver and a controller; the laser transmitter and the laser receiver are both arranged on the frame and are respectively located on both sides of the first conveyor belt, and the laser transmitter is used to emit laser; the laser receiver is used to receive the laser emitted by the laser transmitter, and convert the received laser information into a laser signal and input it into the controller; the controller is fixedly arranged on the frame, and the controller is electrically connected to the laser receiver, the laser transmitter and the electric telescopic rod, and the controller is used to receive the laser signal transmitted by the laser receiver and control the working state of the electric telescopic rod.

[0012] By adopting the above technical solution, the laser transmitter and the laser receiver are always in working state. When no capsule passes through, the laser emitted by the laser transmitter is completely received by the laser receiver. When a hollow capsule passes through, part of the laser emitted by the laser transmitter is received by the laser receiver through the hollow capsule. When a qualified capsule passes through, the amount of laser received by the laser receiver is less than the amount of laser received when the hollow capsule passes through. The amount of laser received by the laser receiver is used to determine whether the capsule is a hollow capsule, thereby realizing the detection and identification of the capsule.

[0013] Optionally, the conveying assembly also includes a second conveyor belt and a second conveyor pulley; the second conveyor belt is arranged to be inclined downward, and the second conveyor belt is located on the top of the first conveyor belt; the feeding box is arranged on the top of the second conveyor belt; two second conveyor pulleys are provided, and the second conveyor pulleys are rotatably connected to the frame, and the second conveyor belt is wound around the two second conveyor pulleys; a transmission assembly is provided on the frame, and the transmission assembly is used to transmit the power of the motor to the second conveyor pulley, and make the rotation direction of the second conveyor pulley opposite to the rotation direction of the first conveyor pulley.

[0014] By adopting the above technical solution, when the capsule flows out from the discharge port, it falls onto the second conveyor belt and slides downward under the action of its own gravity. Since the second conveyor belt rotates upward, the capsule falls on the second conveyor belt at a slower speed. When the capsule falls onto the first conveyor belt, the first conveyor belt rotates, so that the front and rear capsules are separated by a certain distance, so that the capsule passes through the position of the laser receiver and the laser transmitter individually, avoiding the simultaneous detection of multiple capsules and affecting the detection accuracy.

[0015] Optionally, the transmission assembly includes a first gear and a second gear; the first gear is coaxially fixedly connected to the motor output shaft; the second gear is coaxially fixedly connected to one of the second conveyor belt wheels; and the first gear and the second gear are meshed.

[0016] By adopting the above technical solution, when the hollow capsules are removed, the motor drives the first conveyor pulley to rotate, and the first transmission pulley drives the first gear to rotate, thereby causing the second gear to rotate, and the second gear drives the second conveyor pulley to rotate, and the second conveyor belt rotates accordingly, and the rotation direction is opposite to that of the first conveyor belt.

[0017] Optionally, the bottom of the feeding box is tapered in a vertically downward direction; the discharge port is a rectangular groove, and the discharge port can only accommodate one capsule for discharge.

[0018] By adopting the above technical solution, the bottom of the feeding box is set to a constricted shape, so that the capsule can fall from the discharge port under the action of its own gravity. At the same time, the discharge port can only accommodate one capsule to be discharged, so that the capsules fall one by one onto the second conveyor belt, so that the capsules are single when passing through the laser transmitter and the laser receiver, avoiding multiple capsules from being detected at the same time, affecting the detection accuracy.

[0019] Optionally, a hollow capsule storage box is provided on the frame, the hollow capsule storage box is located at the bottom of the first conveyor belt, and is used to store capsules pushed out by the push plate; a qualified capsule storage box is provided on the frame, the qualified capsule storage box is located at the bottom of the first conveyor belt, and is used to store capsules conveyed by the first conveyor belt.

[0020] By adopting the above technical solution, the rejected hollow capsules are collected by using the hollow capsule storage box for subsequent recycling, and the qualified capsules are collected by using the qualified capsule storage box for subsequent processing.

[0021] Optionally, the conveying assembly also includes a first receiving plate and a second receiving plate; the first receiving plate and the second receiving plate are both fixedly arranged on the frame, the first receiving plate is used to allow the capsules on the second conveyor belt to slide smoothly onto the first receiving plate, and the second receiving plate is used to allow the capsules on the first conveyor belt to slide smoothly into the qualified capsule storage box.

[0022] By adopting the above technical solution, a first receiving plate and a second receiving plate are set, so that the capsules on the second conveyor belt can slide smoothly onto the first receiving plate, and the capsules on the first conveyor belt can slide smoothly into the qualified capsule storage box, thereby preventing the capsules from falling from the gap between the first conveyor belt and the second conveyor belt, and preventing the qualified capsules from being damaged when falling.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] By setting up the detection component and the rejection component, when the hollow capsules are rejected, the capsules are inspected by the detection component to distinguish the hollow capsules from the qualified capsules in the capsules, and then the hollow capsules are rejected by the rejection component. The hollow capsules are automatically rejected, which not only saves manpower but also improves the rejection accuracy of the hollow capsules.

[0025] By setting a conveying component and a transmission component, when the capsule flows out from the discharge port, it falls onto the second conveyor belt and slides downward under the action of its own gravity. Since the second conveyor belt rotates upward, the capsule falls on the second conveyor belt at a slower speed. When the capsule falls onto the first conveyor belt, the first conveyor belt rotates, so that the front and rear capsules are separated by a certain distance, so that the capsule passes through the position of the laser receiver and the laser transmitter individually, avoiding the simultaneous detection of multiple capsules and affecting the detection accuracy.

[0036] The following is combined with Figure 1-3 This application is described in further detail.

[0037] The present application embodiment discloses a hollow capsule rejecting device. Figure 1 and Figure 2 A hollow capsule rejection device includes a frame 1, a feeding box 2, a conveying component 3, a rejection component 4 and a detection component 5. The feeding box 2 is vertically fixed on the frame 1 and has a top opening structure. A discharge port 21 is provided at the bottom of the feeding box 2, and the discharge port 21 is connected to the inside of the feeding box 2. A qualified capsule storage box 12 is provided on the frame 1, and the qualified capsule storage box 12 has a top opening structure. The conveying component 3 is arranged on the frame 1, and the conveying component 3 is used to transport the capsules flowing out of the discharge port 21 to the qualified capsule storage box 12. The rejection component 4 is arranged on the frame 1, and the rejection component 4 is used to reject the hollow capsules contained in the capsules transported by the conveying component 3. The detection component 5 is arranged on the frame 1, and is used to detect the capsules transported by the conveying component 3 and control the working state of the rejection component 4.

[0038] When removing the hollow capsules, the operator pours the capsules into the feeding box 2, and the capsules flow out from the discharge port 21 under the action of their own gravity. The flowing capsules are conveyed to the qualified capsule storage box 12 by the conveying component 3. During the conveying process, the hollow capsules are distinguished by the detection component 5, and then the hollow capsules are removed by the rejection component 4.

[0039] Reference Figure 1 and Figure 2 The feeding box 2 is a top opening structure, and the bottom of the feeding box 2 is a constricted shape in the vertical downward direction. The discharge port 21 is a rectangular slot, and the discharge port 21 can only accommodate one capsule to pass through. The qualified capsule storage box 12 is a top opening structure.

[0040] Reference Figure 2 and Figure 3 The conveying assembly 3 includes a first conveyor pulley 32, a first conveyor belt 31, a motor 33, a second conveyor pulley 35, a second conveyor belt 34, a first receiving plate 36 and a second receiving plate 37. Two first conveyor pulleys 32 are horizontally arranged, and the two first conveyor pulleys 32 are at the same height. The first conveyor pulleys 32 are rotatably connected to the frame 1. The first conveyor belt 31 is wound around the first conveyor pulley 32. The motor 33 is fixedly arranged on the frame 1, and the output shaft of the motor 33 is inserted into the frame 1 and is coaxially fixedly connected with the first conveyor pulley 32.

[0041] Two second conveyor belt wheels 35 are horizontally arranged, and the two second conveyor belt wheels 35 are at different heights. The second conveyor belt wheels 35 are rotatably connected to the frame 1. The two second conveyor belt wheels 35 are both located above the first conveyor belt 31. The second conveyor belt 34 is wound around the second conveyor belt wheels 35. The second conveyor belt 34 is tilted downward in a direction close to the first conveyor belt 31. The feeding box 2 is located above the second conveyor belt 34. The qualified capsule storage box 12 is located at one end of the first conveyor belt 31 away from the second conveyor belt 34.

[0042] The first receiving plate 36 is located at one end of the second conveyor belt 34 close to the first conveyor belt 31, and the first receiving plate 36 is an arc-shaped plate. The first receiving plate 36 is arranged obliquely downward in the direction close to the first conveyor belt 31. One end of the first receiving plate 36 abuts against the first conveyor belt 31, and the other end abuts against the second conveyor belt 34. The first receiving plate 36 is fixedly connected to the frame 1. The second receiving plate 37 is located at one end of the first conveyor belt 31 away from the second conveyor belt 34. The second receiving plate 37 is an arc-shaped plate. The second receiving plate 37 is arranged obliquely downward in the direction close to the qualified capsule storage box 12. One end of the second receiving plate 37 abuts against the first conveyor belt 31, and the other end is located in the qualified capsule storage box 12. The second receiving plate 37 is fixedly connected to the frame 1.

[0043] Reference Figure 1 and Figure 2 The frame 1 is provided with a transmission assembly 6, which includes a first gear 61 and a second gear 62. The first gear 61 is coaxially fixedly connected to the output shaft of the motor 33. The second gear 62 is coaxially fixedly connected to one of the second conveyor pulleys 35, and the second gear 62 is meshed with the first gear 61.

[0044] When the hollow capsules are being removed, the motor 33 is always in working condition. The motor 33 drives the first conveyor pulley 32 to rotate, thereby driving the first conveyor belt 31 to rotate in the opposite direction close to the qualified capsule storage box 12. At the same time, the first gear 61 rotates under the drive of the first conveyor pulley 32, so that the second gear 62 rotates in the opposite direction, thereby driving the second conveyor belt 34 to rotate in the opposite direction to the first conveyor belt 31.

[0045] The operator pours the capsules into the feeding box 2. The capsules flow out from the discharge port 21 one by one under their own gravity and fall onto the second conveyor belt 34. The capsules slide downward under their own gravity. Since the second conveyor belt 34 rotates upward, the speed at which the capsules slide downward is relatively slow. The capsules fall onto the first conveyor belt 31 along the first receiving plate 36. Under the action of the first conveyor belt 31, the capsules quickly approach the qualified capsule storage box 12, so that there is a certain distance between the two capsules. The capsules finally fall into the qualified capsule storage box 12 along the second receiving plate 37.

[0046] Reference Figure 1 and Figure 2 The rejection assembly 4 includes a push plate 41 and an electric telescopic rod 42. The push plate 41 is vertically arranged on the top of the first conveyor belt 31. The electric telescopic rod 42 is arranged horizontally, and the telescopic axis of the electric telescopic rod 42 is arranged perpendicular to the rotation direction of the first conveyor belt 31. The fixed end of the electric telescopic rod 42 is fixedly arranged on the frame 1, and the movable end of the electric telescopic rod 42 is fixedly connected to the push plate 41. A hollow capsule storage box 11 is arranged on the side of the first conveyor belt 31 away from the electric telescopic rod 42. The hollow capsule storage box 11 is fixedly arranged on the frame 1, and the hollow capsule storage box 11 is a top opening structure.

[0047] The detection component 5 includes a laser transmitter 51, a laser receiver 52 and a controller 53. The laser transmitter 51 and the laser receiver 52 are respectively located on both sides of the first conveyor belt 31, and are both fixedly connected to the frame 1. The laser transmitter 51 is used to emit laser. The laser receiver 52 is used to receive the laser emitted by the laser transmitter 51, and convert the received laser information into a laser signal and input it into the controller 53. The controller 53 is fixedly arranged on the frame 1, and the controller 53 is electrically connected to the laser receiver 52, the laser transmitter 51 and the electric telescopic rod 42. The controller 53 is used to receive the laser signal transmitted by the laser receiver 52 and control the working state of the electric telescopic rod 42.

[0048] When the capsule moves to the qualified capsule storage box 12 under the action of the first conveyor belt 31, the laser transmitter 51 and the laser receiver 52 are always in working state. When the hollow capsule passes through, part of the laser emitted by the laser transmitter 51 passes through the hollow capsule and is received by the laser receiver 52. At this time, the controller 53 controls the electric telescopic rod 42 to extend after a short delay, and pushes the hollow capsule moved to the position of the push plate 41 into the hollow capsule storage box 11, completing the detection and removal of the hollow capsule.

[0049] The implementation principle of a hollow capsule rejection device in the embodiment of the present application is:

[0050] When the hollow capsules are removed, the operator pours the capsules into the feeding box 2, and the capsules fall onto the second conveyor belt 34. The capsules slide downward under their own gravity. Since the second conveyor belt 34 rotates upward, the speed at which the capsules slide downward is relatively slow. Then the capsules fall onto the first conveyor belt 31. Since the first conveyor belt 31 rotates at a relatively fast speed, there is a certain distance between the front and rear capsules, and the capsules pass through the positions of the laser receiver 52 and the laser transmitter 51 alone.

[0051] During the process again, the laser transmitter 51 and the laser receiver 52 are always in working state. When the hollow capsule passes through, part of the laser emitted by the laser transmitter 51 passes through the hollow capsule and is received by the laser receiver 52. At this time, the controller 53 controls the electric telescopic rod 42 to extend after a short delay, and pushes the hollow capsule moved to the position of the push plate 41 into the hollow capsule storage box 11. The qualified capsule continues to move forward and enters the qualified capsule storage box 12, completing the detection and removal of the hollow capsule.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
