Description

Technical Field

[0001] The utility model relates to the technical field of medicine bottle detection, in particular to a conveying component and a detection device for detecting foreign matter at the bottom of a medicine bottle. Background Art

[0002] In the production process of medicine bottles in the pharmaceutical industry, defects and broken bottles may occur during the process of bottle sorting, bottle washing and drying. At this time, the medicine bottles themselves contain foreign matter and are then filled. Some foreign matter is hidden in the medicine in the bottle. For solid medicines, the foreign matter is located inside the medicine after filling, making detection more difficult. Secondly, if detection is performed after filling, it will cause waste of medicine.

[0003] For example, the Chinese invention patent application with publication number CN115711891A relates to a system for detecting the mouth and bottom of a vial, including a conveyor line and a conveying mechanism, wherein a detection mechanism is arranged on the conveying mechanism, and the detection mechanism detects the mouth and bottom defects of the vial conveyed by the conveying mechanism through a detection camera, wherein the detection camera includes a first camera, a second camera, a third camera and a fourth camera arranged in sequence, which correspond to the first camera station, the second camera station, the third camera station and the fourth camera station arranged above the conveying mechanism, respectively. The present invention effectively detects the mouth defects, bottom defects and bottom stress defects of the vial by setting four groups of camera stations, using cameras and light sources, and kicks out defective products through a kicking device, thereby ensuring the mouth and bottom quality of the vial.

[0004] When conveying medicine bottles, the existing detection devices all use double-sided belts to clamp the medicine bottles in order to allow the bottom of the medicine bottles to leak out. Although the bottom of the medicine bottle leaks out, the bottle body of the medicine bottle is largely blocked by the belts. This makes it impossible for the detection camera to detect foreign objects at the bottom of the bottle from the side, and it is also impossible to detect defects in the bottle body. The detection accuracy is low and the detection range is small.

[0005] Based on this, the utility model designs a conveying assembly and a detection device for detecting foreign matter at the bottom of a medicine bottle to solve the above-mentioned problem. Utility Model Content

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A conveying assembly for detecting foreign objects at the bottom of a medicine bottle comprises a detection track and a conveying unit. The detection track is used to contact the bottom surface of the mouth of the medicine bottle to suspend the medicine bottle on the detection track. The detection track comprises two bottleneck fences arranged at intervals. The spacing between the two bottleneck fences is smaller than the outer diameter of the mouth of the medicine bottle and larger than the outer diameter of the bottleneck of the medicine bottle. The detection track is used to contact both sides of the bottom surface of the mouth of the medicine bottle to suspend the medicine bottle between the two bottleneck fences. The conveying unit is used to drive the medicine bottle to move on the detection track, and the portion of the conveying unit used to contact the medicine bottle can move closer to or away from the bottleneck fence.

[0008] As a further solution of the utility model, the spacing between the bottleneck fences matches the outer diameter of the bottleneck of the medicine bottle.

[0009] As a further solution of the utility model, the bottleneck fence consists of a movable end for contacting the medicine bottle and a fixed end for installing the movable end. The movable end is movably matched with the fixed end and a clamping unit for fixing the position of the movable end is provided on the fixed end, so that the distance between the two movable ends can be adjusted.

[0010] As a further solution of the present invention, the conveying unit includes a contact part for pushing the medicine bottle and a driving component for controlling the movement of the contact part, and the driving component includes a first driving member for driving the contact part to approach or move away from the bottleneck fence and a second driving member for driving the contact part to move along the length direction of the bottleneck fence.

[0011] As a further solution of the utility model, the contact portion adopts a single contact piece to contact one side of the medicine bottle or a double contact piece to clamp and push the medicine bottle on both sides.

[0012] As a further solution of the utility model, two contact portions are arranged at intervals along the length direction of the bottleneck fence, and the two contact portions are driven by the same driving component.

[0013] A device for detecting foreign matter at the bottom of a medicine bottle, comprising a conveying assembly for detecting foreign matter at the bottom of a medicine bottle, and also comprising a bottle pushing assembly, a waste rejecting assembly and a detection unit. The bottle pushing assembly is arranged at one end of a detection track, and is used to convey the medicine bottles into the detection track. The waste rejecting assembly is arranged at the end of the detection track away from the bottle pushing assembly, and is used to convey the medicine bottles leaving the detection track to the next process and reject the waste medicine bottles. The detection unit comprises a plurality of detection cameras installed around the detection track and a matching light source, and is used to detect the bottom of the medicine bottles from multiple directions.

[0014] As a further solution of the utility model, a bottle shortage detection laser switch is installed on the bottle pushing assembly.

[0015] As a further solution of the utility model, an auxiliary power device is installed at the bottom of the bottle feeding track of the bottle pushing assembly, and the auxiliary power device is used to ensure that the medicine bottle enters the bottle pushing assembly.

[0016] As a further solution of the utility model, the auxiliary power device includes a bottle pushing plate whose top surface is flush with the top surface of the bottle feeding track of the bottle pushing assembly and a driving motor for driving the bottle pushing plate to rotate. The side of the bottle feeding track of the bottle pushing assembly is provided with an arc groove for the bottle pushing plate to be inserted into.

[0017] The utility model has the following beneficial effects:

[0018] The device suspends the medicine bottle on two bottleneck fences, so that the part below the bottleneck of the medicine bottle will be completely exposed. At the same time, the part of the conveying unit used to push the medicine bottle to move can be moved closer to or away from the medicine bottle. After pushing the medicine bottle to the designated detection position, it can be moved away from the medicine bottle, so that the bottle body of the medicine bottle is completely exposed, which can effectively reduce the interference of the appearance of other parts on the detection image, and the detection range is larger, thereby improving the detection accuracy and reducing the missed detection rate.

[0028] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0029] See also Figure 1-5 The utility model provides a technical solution: a conveying assembly for detecting foreign objects at the bottom of a medicine bottle, comprising a detection track 1 and a conveying unit 2. The detection track 1 is used to contact the bottom surface of the mouth of the medicine bottle. The medicine bottle is hung on the detection track 1, so that the part below the bottleneck of the medicine bottle will be completely leaked, reducing the obstruction of the position of the medicine bottle body, and the foreign objects at the bottom of the bottle can be detected from more angles, greatly improving the accuracy of the detection.

[0030] Specifically, the detection track 1 includes two bottleneck fences 11 arranged at intervals, and the spacing between the two bottleneck fences 11 is smaller than the outer diameter of the bottle mouth of the medicine bottle and larger than the outer diameter of the bottle neck of the medicine bottle, and is used to contact the two sides of the bottom surface of the bottle mouth of the medicine bottle so that the medicine bottle is suspended between the two bottleneck fences 11. The conveying unit 2 is used to push the medicine bottle to move on the detection track 1, and the part used to contact the medicine bottle can move closer to or away from the bottleneck fence 11, so that the medicine bottle can be moved to the detection position and leave the detection position. The medicine bottle is suspended on the detection track 1 by contacting the bottom surface of the bottle mouth of the medicine bottle through the two bottleneck fences 11, so that the part below the bottleneck of the medicine bottle can be completely leaked and no longer blocked. When the bottom of the medicine bottle is detected for foreign objects, more detection angles can be provided, which greatly increases the accuracy of the bottom detection of the medicine bottle.

[0031] Preferably, the spacing between the bottleneck fences 11 just matches the outer diameter of the bottleneck of the medicine bottle, so that the bottleneck fence 11 can be clamped on the bottleneck of the medicine bottle by two bottleneck fences 11 while contacting the bottom surface of the bottle mouth, so that after the medicine bottle enters between the bottleneck fences 11, it can only move along the track formed between the two bottleneck fences 11, thereby ensuring the accuracy of the position of the medicine bottle.

[0032] like Figure 3As shown, the bottleneck fence 11 consists of a movable end 111 for contacting the medicine bottle and a fixed end 112 for installing the movable end 111. The movable end 111 is movably matched with the fixed end 112 and a clamping unit for fixing the position of the movable end 111 is provided on the fixed end 112, so that the distance between the two movable ends 111 can be adjusted.

[0033] In this embodiment, since the bottleneck fence 11 contacts the medicine bottle through the movable end 111, the distance between the two movable ends 111 can be changed by adjusting the position of the movable end 111 on the fixed end 112, so as to adapt to medicine bottles of different specifications;

[0034] Specifically, two upper and lower clamping plates are provided on the upper end of the fixed end 112, the movable end 111 is installed in the upper and lower clamping plates, and a waist groove is opened on the surface of the movable end 111. The clamping unit is a bolt that penetrates the upper and lower clamping plates and the waist groove on the surface of the movable end 111. The upper and lower clamping plates clamp the movable end 111 by tightening the nut on the surface of the bolt to fix the position of the movable end 111.

[0035] Preferably, two parallel waist grooves are opened on the surface of the movable end 111, and the movable end 111 is fixed by two bolts passing through the two waist grooves respectively. At the same time, the moving direction of the movable end 111 is limited by the two bolts to prevent the movable end 111 from tilting.

[0036] like Figure 4 As shown, the conveying unit 2 includes a contact portion 21 for pushing the medicine bottle and a driving component for controlling the movement of the contact portion 21, and the driving component includes a first driving member 22 for driving the contact portion 21 to approach or move away from the bottleneck fence 11 and a second driving member 23 for driving the contact portion 21 to move along the length direction of the bottleneck fence 11.

[0037] In this embodiment, the first driving member 22 controls the contact part 21 to approach and move away from the medicine bottle, and the second driving member controls the contact part 21 to move along the length direction of the bottleneck fence 11. After the contact part 21 approaches the medicine bottle, the second driving member 23 drives the contact part 21 to move to push the medicine bottle to move. After the medicine bottle moves into place, the first driving member 22 drives the contact part 21 to move in the direction away from the bottleneck fence 11, so that the contact part 21 is away from the medicine bottle on the bottleneck fence 11. The contact part 21 does not block the medicine bottle, and the part below the bottleneck of the medicine bottle can be completely exposed, eliminating the influence of the contact part 21 on the detection. It should be understood that the first driving member 22 and the second driving member 23 can adopt linear transmission mechanisms such as cylinders, screw rods 232, electric push rods, cams, gear racks, linear motors 231, etc.

[0038] Preferably, the second driving member 23 is composed of a screw rod 232, a motor 231 for driving the screw rod 232, and a mounting seat 233 for mounting the second driving member 23. The screw rod 232 is rotatably mounted on the base, the motor 231 is fixedly mounted on the base, the mounting seat 233 is slidably mounted on the base and threadedly meshed with the screw rod 232, and the motor 231 drives the screw rod 232 to rotate to realize the movement of the mounting seat 233. The first driving member 22 adopts a cylinder, which is fixed to the upper end of the mounting seat 233, and the contact part 21 is fixedly mounted on the piston rod of the cylinder. The overall device is located on one side of the bottleneck fence 11 and the piston rod of the cylinder faces the bottleneck fence 11. The screw rod 232 is in the same direction as the bottleneck fence 11. The contact part 21 can be moved close to or away from the bottleneck fence 11 by controlling the extension and retraction of the piston rod of the cylinder, and the motor 231 drives the screw rod 232 to rotate, which can drive the mounting seat 233 and the cylinder and contact part 21 on the mounting seat 233 to move along the length direction of the bottleneck fence 11.

[0039] like Figure 4 As shown, the contact portion 21 uses a single contact piece to contact one side of the medicine bottle or a double contact piece to clamp and push the medicine bottle on both sides.

[0040] In this embodiment, the contact portion 21 can use a single contact piece to contact one side of the medicine bottle to push the medicine bottle, or use double contact pieces to contact both sides of the medicine bottle to clamp the medicine bottle and then push the medicine bottle. After the double contact pieces contact both sides of the medicine bottle to clamp the medicine bottle, the shaking of the medicine bottle during the movement can be eliminated, the position of the medicine bottle on the bottleneck fence 11 can be accurately controlled, and the error can be reduced.

[0041] As shown in the figure, two contact parts 21 are arranged at intervals along the length direction of the bottleneck fence 11, and the two contact parts 21 are driven by the same driving component.

[0042] In this embodiment, two contact parts 21 are installed on the first driving member 22, and there is a certain interval between the two contact parts 21, so that when one of the contact parts 21 pushes the medicine bottle at the detection position of the bottleneck fence 11 out of the bottleneck fence 11, a new medicine bottle can be pushed into the detection position of the bottleneck fence 11 through the other contact part 21, thereby realizing seamless loading and unloading and increasing the efficiency of detection.

[0043] like Figure 1-5As shown, a device for detecting foreign matter at the bottom of a medicine bottle includes a conveying assembly for detecting foreign matter at the bottom of a medicine bottle, and also includes a bottle pushing assembly 3, a waste rejection assembly 4 and a detection unit 5. The bottle pushing assembly 3 is arranged at one end of a detection track 1, and is used to convey the medicine bottles into the detection track 1. The waste rejection assembly 4 is arranged at the end of the detection track 1 away from the bottle pushing assembly 3, and is used to convey the medicine bottles leaving the detection track 1 to the next process and reject the waste medicine bottles. The detection unit 5 includes a plurality of detection cameras 51 installed around the detection track 1 and a matching light source, which are used to detect the bottom of the medicine bottles from multiple directions.

[0044] In this embodiment, the medicine bottles are fed into the detection track 1 by the bottle pushing assembly 3, the medicine bottles on the detection track 1 are inspected for foreign objects at the bottom of the bottles by the detection unit 5, the waste medicine bottles are rejected by the waste rejection assembly 4 and the good medicine bottles are transported to the next process.

[0045] Specifically, the bottle pushing assembly 3, the detection unit 5, the waste rejection assembly 4, the detection track 1 and the conveying unit 2 are all installed on the machine body, the detection track 1 is installed in the middle, the bottle pushing assembly 3 and the waste rejection assembly 4 are respectively installed at both ends of the detection track 1, the bottle pushing assembly 3 includes a bottle inlet track 31 and a bottle inlet driving member 32 located on the side of the bottle inlet track 31, the bottle inlet driving member 32 can drive the medicine bottles in the bottle inlet track 31 to enter the detection track 1, the waste rejection assembly 4 includes a bottle outlet track 41 and a waste rejection air hole 42 located on the side of the bottle outlet track 41, the bottle outlet track 41 is open on one side opposite to the waste rejection air hole 42, when working, the medicine bottle enters the bottle inlet track 31 through the front bottle sorting plate, and then moves along the bottle inlet track 31 to enter the detection track 1 under the drive of the bottle inlet driving member 32, and the surrounding of the detection track 1 A plurality of inspection cameras 51 are fixedly installed around the inspection track 1, which are aimed at the inspection track 1 from different directions respectively. The medicine bottle is moved to the inspection position on the inspection track 1 by the conveying unit 2 and then stopped. Next, the medicine bottle is imaged from different angles by the inspection camera 51. After the image is taken, the data is transmitted to the industrial computer for calculation. The appearance of the medicine bottle and whether there are foreign objects inside the medicine bottle are inspected and calculated to determine whether the medicine bottle is a defective product. Then the conveying unit 2 drives the medicine bottle to continue to move away from the inspection track 1 and enter the bottle output track 41. A conveyor belt is provided at the bottom of the bottle output track 41. The conveyor belt drives the medicine bottle to move along the bottle output track 41. When the medicine bottle passes through the waste rejection air hole 42, the good medicine bottle can pass through the waste rejection air hole 42 smoothly, while the defective medicine bottle will be blown off by the waste rejection air hole 42, thereby realizing the rejection of the medicine bottle.

[0046] Furthermore, the detection camera 51 can be installed directly below the detection track 1 and vertically upward toward the detection track 1 , or can be installed on the side of the detection track 1 and horizontally or obliquely toward the detection track 1 .

[0047] Furthermore, the bottle feeding drive member 32 can adopt a linear transmission mechanism such as a dial wheel, a trapezoidal screw rod 232, a cam, a synchronous belt sliding module, an electric push rod, a cylinder, a gear rack, a linear motor 231, etc.

[0048] Furthermore, two sets of bottle pushing assemblies 3, detection units 5, waste rejection assemblies 4, detection tracks 1 and conveying units 2 can be installed on the same machine body, so that the two conveying units 2 can use the same second driving member 23, and the bottom of the two bottle outlet tracks 41 can use the same conveyor belt, which saves costs and reduces floor space.

[0049] like Figure 5 As shown, a bottle shortage detection laser switch is installed on the bottle pushing assembly 3.

[0050] In this embodiment, the bottle shortage detection laser switch feeds back a signal to the bottle feeding drive 32 to control its start and stop, so that the medicine bottles are arranged in sequence on the bottle feeding track 31 to prevent bottle shortage.

[0051] like Figure 5 As shown, an auxiliary power device 34 is installed at the bottom of the bottle feeding track 31 of the bottle pushing assembly 3, and the auxiliary power device 34 is used to ensure that the medicine bottle enters the bottle pushing assembly 3.

[0052] In this embodiment, when the medicine bottles enter the bottle feed track 31 from the bottle sorting tray, the thrust of the front bottle sorting tray may be insufficient and the medicine bottles cannot be transported normally, resulting in the malfunction of other devices such as the rear end bottle feed drive 32. An auxiliary power device 34 is installed at the bottom of the bottle feed track 31 to ensure that the medicine bottles can be smoothly moved to the position where the bottle feed drive 32 can drive.

[0053] Specifically, the auxiliary power device 34 includes a bottle pushing plate whose top surface is flush with the top surface of the bottle feeding track 31 of the bottle pushing assembly 3 and a driving motor for driving the bottle pushing plate to rotate. The driving motor is installed at the bottom of the bottle pushing plate. The bottle feeding track 31 of the bottle pushing assembly 3 is provided with an arc groove for the bottle pushing plate to be inserted into the side. After the medicine bottle enters the bottle feeding track 31 from the bottle sorting plate, it will first contact the upper surface of the bottle pushing plate. At this time, the bottle pushing plate is in a rotating state driven by the driving motor. The bottle pushing plate can give the medicine bottle on its upper end surface a forward thrust, so that the medicine bottle can be smoothly moved to a position where the bottle feeding drive member 32 can contact it, so that the bottle feeding drive member 32 can smoothly push the medicine bottle to move.

[0054] 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.
