Description

Technical Field

[0001] The utility model belongs to the technical field of medicine production and processing equipment, and particularly relates to an automatic medicine bottle cap sorting device. Background Art

[0002] During the production and processing of bottled medicine bottles, after the medicine is filled into the bottle, the sealing cap needs to be screwed onto the bottle opening to seal it. The entire process is completed on the automatic capping equipment; the bottle caps to be sealed need to be processed again on the capping part of the equipment. After the capping is sorted, the bottle caps are arranged and then placed on the bottle opening one by one, and then pressed and tightened.

[0003] The process of sorting bottle caps is as follows: the messy bottle caps are placed in the hopper, and the climbing conveyor belt is in the process of conveying. The bottle caps can be stuck on the board on the conveyor belt and follow the climbing. After climbing to a certain height, the bottle caps in the conveyor belt will be pushed from one side of the conveyor belt into the slide-out channel by the action of the jet assembly under the action of air blowing, and then fall into the cap sorting queue channel from the slide-out channel. The sorted caps are arranged in the cap sorting queue channel, waiting to be buckled on the opening of the bottle from the exit; in order to make the bottle caps match the opening of the medicine bottle, the cap openings should face downwards in the cap sorting queue channel; in order to ensure that the cap openings are all facing downwards, the caps should have their openings facing downwards when they are conveyed by the conveyor belt. Keep the back facing the conveyor belt outward; in order to ensure that the openings of the caps conveyed by the conveyor belt in the hopper enter the slide-out channel in the outward direction, the operator is required to observe the caps on the conveyor belt at the hopper and manually pick up the caps facing the wrong direction. This not only increases the workload of the operator, but also poses a safety hazard. The operator may be accidentally injured during the operation of the machine; another way is to set a vibration component or a pneumatic component in the hopper or at the position where the caps are about to be put on the conveyor belt to flip the bottle caps. This flipping method not only may cause the caps to be missed, but also may cause the caps facing the correct direction to be flipped into the wrong direction. Utility Model Content

[0004] The present invention provides an automatic cap-sorting device for medicine bottle caps. The conveyor belt of the device is close to the feeding side, and a visual image acquisition component and a mechanical shifting component are arranged directly above the conveyor belt. When the cap moves to directly below the visual image acquisition component, the image of the cap passing by is collected to determine the orientation of the cap. If the collected image is processed by the PLC and it is determined that the orientation of the cap is inconsistent, the PLC controls the mechanical shifting component to move above the corresponding cap, and then the mechanical shifting component will shift the cap off the conveyor belt and drop it into the hopper again. Through visual monitoring and mechanical shifting, the number of caps that are missed from being flipped can be minimized to the greatest extent, so that the orientation of the caps on the conveyor belt remains consistent. The present invention solves the problem that many caps with inconsistent orientations may be missed from being flipped when the current cap-sorting equipment is used to sort the caps.

DETAILED DESCRIPTION

[0070] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0071] Example 1

[0072] An automatic cap sorting device for medicine bottle caps, comprising: a hopper 3, a lifting climbing frame 1, a conveyor belt 2, a conveyor belt driving component, a monitoring component moving frame 9, a monitoring and rejection component, a pushing component, a sliding channel 4, and a cap sorting queuing channel 5;

[0073] like Figure 1 As shown, the lifting climbing frame 1 is lifted in a slope shape, and the entire lifting climbing frame 1 descends from the highest point to the lowest point, and extends a horizontal section at the lowest point;

[0074] like Figure 3 As shown, an active transmission roller 102 is provided at the highest point of the lifting climbing frame 1. The center of one end face of the active transmission roller 102 is rotatably connected to one side of the lifting climbing frame 1 through a rotating shaft rod. A rotating shaft rod is also provided at the center of the other end face of the active transmission shaft 102. The rotating shaft rod passes through the other side of the lifting climbing frame 1 and is connected to the rotor of the motor 8. The motor 8 drives the active transmission roller 102 to rotate. A driven transmission roller 103 is provided at the lowest point of the lifting climbing frame 1 and on the tail side of the lowest horizontal section. The two ends of the driven transmission roller 103 are rotatably connected to the two sides of the lifting climbing frame 1 through a rotating shaft rod. In addition to the above-mentioned driven transmission roller 103 located at the tail side of the horizontal section, several driven transmission rollers 103 can be arranged between the above-mentioned driven transmission roller 103 and the active transmission roller 102 to assist in transmission; these driven transmission rollers 103 are also provided with rotating shafts at both end faces, and are rotatably connected to both sides of the lifting climbing frame 1; a conveyor belt 2 is arranged on the active transmission roller 102 and the driven transmission roller 103, and the contact surface between the transmission roller and the conveyor belt 2 has greater friction, or a tooth structure is provided on the contact surface of the transmission roller and the conveyor belt 2, and the contact surfaces of the two are engaged through teeth.

[0075] like Figure 1 As shown, a hopper 3 is provided on the lowest horizontal section of the lifting climbing frame 1. Part of the bottom of the hopper 3 is an open structure. The bottom of the hopper 3 is just above the horizontal section conveyor belt, that is, it can be understood that the horizontal section conveyor belt is used as the bottom surface of the hopper 3; the bottle caps entering the hopper 3 can fall on the horizontal section conveyor belt.

[0076] The running direction of the conveyor belt 2 is from bottom to top, and then it repeats in a cycle. Under the action of the conveyor belt 2, the bottle caps in the hopper 3 need to be conveyed upward on the conveyor belt 2. Since the conveyor belt 2 is a sloped structure like the lifting climbing frame 1, if there is no supporting structure for the bottle caps on the surface of the conveyor belt 2, it is difficult for the bottle caps to be conveyed to a high place by following the conveyor belt 2. Therefore, a number of planks 201 are set at equal intervals on the surface of the conveyor belt 2. The planks 201 protrude from the surface of the conveyor belt 2 by a certain width. When the bottle caps enter the conveyor belt 2, they can be located on the protruding planks 201, which is equivalent to providing the bottle caps with a supporting structure, so that the bottle caps will not slip during the process of being conveyed upward with the conveyor belt 2.

[0077] When the bottle caps follow the conveyor belt 2 to a certain height, they need to enter the slide-out channel 4 from the conveyor belt 2, and then enter the cap-sorting channel 5 from the slide-out channel 4. The exit end of the cap-sorting channel 5 is located above the conveyor belt of the capping machine. When the bottle caps pass through the capping machine, the bottle caps at the exit of the cap-sorting channel 5 will automatically buckle on the opening of the bottle. Figure 4 As shown, the interior of the slide-out channel 4 is hollow, with an entrance 401 on the left side and an exit 402 on the right side of the bottom surface; the exit 402 of the slide-out channel 4 is connected to the entrance of the cover queuing channel 5; Figure 2 As shown, the entrance 401 of the slide-out channel 4 is arranged on a side close to the height of the lifting climbing frame 1, and the lower bottom surface of the slide-out channel 4 is a sloped structure from high to low from the side of the lifting climbing frame 1 to the side of the cap sorting and queuing channel 5; when the bottle cap follows the lifting climbing frame 1 to move to this position, it can roll to one side and enter the slide-out channel 4 from the entrance 401 of the slide-out channel 4.

[0078] Since the butt plate 201 is arranged horizontally on the conveyor belt 2, the bottle caps on the butt plate 201 generally remain stationary on the butt plate 201 when no external force is applied, and will not roll from any side. Therefore, in order to allow the bottle caps to roll on the butt plate 201 and smoothly enter the slide-out channel 4, it is necessary to provide a pushing assembly on the opposite side of the slide-out channel 4 to generate external force acting on the bottle caps and push them into the slide-out channel 4.

[0079] The above-mentioned ejection assembly includes: a control box 6, a cylinder 601, a telescopic push rod 602, an air pump 7 and an air flow channel 701;

[0080] like Figure 2 As shown, the control box 6 is arranged on one side close to the height of the lifting climbing frame 1; Figure 7 As shown, an air pump 7 is provided above the control box 6; an air flow channel 701 is provided inside the control box 6; the inlet of the air flow channel 701 is connected to the air pump 7, and the outlet of the air flow channel 701 is provided on the side of the control box 6 facing the lifting climbing frame 1. The air pump 7 blows air from the outlet of the air flow channel 701, acting on the bottle cap on the same plane. Under the push of the air flow, the bottle cap will be pushed into and out of the sliding channel 4;

[0081] The existing bottle cap sorting and conveying equipment uses air spray to push the bottle caps into the slide-out channel 4. However, if there are many caps in a row or the caps are heavy, the air jet volume is insufficient to provide sufficient thrust to push all the caps into the slide-out channel 4. The caps that may be at the rear will continue to stay on the conveyor belt 2.

[0082] As a preferred embodiment, in addition to the air spraying mode of action on the lid, this embodiment also provides a mechanical pushing mode of action; Figure 7As shown, a cylinder 601 is provided on the side of the control box 6 facing away from the lifting climbing frame 1, and a telescopic push rod 602 is provided on the cylinder 601; the telescopic push rod 602 passes through the control box 6, and the telescopic section of the telescopic push rod 602 extends from the side of the control box 6 facing the lifting climbing frame 1; the cylinder 601 controls the telescopic push rod 602, which belongs to the existing technology, and its specific structure and principle are not repeated here; the telescopic push rod 602 extends horizontally and acts on the bottle cap, and then cooperates with the air spray, and the combination of the two can ensure that the bottle cap is pushed into the sliding channel 4.

[0083] After the cap enters the slide-out channel 4, it is directly and seamlessly connected to the cap queuing channel 5 from the exit of the slide-out channel 4 and queues to be buckled on the opening of the bottle; Figure 2 As shown, the cap sorting queuing channel 5 is divided into a slope section and a horizontal section; the slope section and the horizontal section are connected in one piece by an arc section channel; the upper end opening of the slope section is the entrance end, which is connected to the exit end of the slide-out channel 4; the open end of the horizontal section is the exit end; the lower bottom surface of the cap sorting queuing channel 5 near the exit end is set as a horizontal section opening 501; the width of the horizontal section opening 501 is smaller than the outer diameter of the bottle cap; after the bottle cap enters the horizontal section of the cap sorting queuing channel, since the width of the horizontal section opening 501 of the lower bottom surface is smaller than the outer diameter of the bottle cap, the bottle cap can be located in the cap sorting queuing channel 5 and will not fall from the horizontal section opening 501; the bottle cap is buckled at the bottle opening from the exit end of the cap sorting queuing channel 5; as shown in FIG. Figure 6 As shown, a side pressure spring piece 502 is provided on each side of the outlet end of the cap sorting queuing channel 5, and an upper pressure spring piece 503 is provided on the upper side of the cap sorting queuing channel 5; the two side pressure spring pieces 502 and the upper pressure spring piece 503 both have a certain curvature; when the two side pressure spring pieces 502 are not subjected to elastic deformation or external force, the narrowest part between the two is smaller than the width of the outlet end of the cap sorting queuing channel 5; when the upper pressure spring piece 503 is not subjected to elastic deformation or external force, its lowest part is lower than the upper side edge of the outlet end of the cap sorting queuing channel 5; an elastic member 504 is provided above the upper pressure spring piece 503, and the elastic member 504 here can be a spring, and a spring is connected to the upper end of the elastic member 504. The lower end of the vertical connecting rod and the upper end of the vertical connecting rod are connected to the support plate above the equipment; the upper pressure spring piece 503 and the elastic member 504 and the vertical connecting rod provided above it are all provided in the existing screw capping equipment, and the support plate connected to the vertical connecting rod is also already provided on the existing screw capping equipment; after the bottle cap is output from the outlet end of the cap sorting queue channel 5, it will be clamped by the side pressure spring pieces 502 on the left and right sides to keep it fixed, and the upper pressure spring piece 503 will press the bottle cap downward in a slightly tilted state, so that when the bottle passes through the bottle cap clamped on the side pressure spring piece 502, the bottle cap will automatically buckle at the opening of the bottle under the drive of the bottle, and then the pressing and screwing of the cap will be completed.

[0084] During the entire conveying and arranging process, the opening direction of the bottle caps should be kept consistent, so as to ensure that the bottle caps entering the horizontal section of the cap sorting and queuing channel all keep their openings facing downwards, so that the bottle caps can be smoothly buckled on the bottle openings; therefore, when the bottle caps are conveyed on the conveyor belt 2, the bottle cap openings need to be kept away from the conveyor belt 2. The bottle caps are randomly put onto the conveyor belt 2, so the bottle caps with inconsistent directions need to be adjusted; the existing equipment corrects the bottle caps with inconsistent directions by manually picking them up, or by setting a vibration component or a pneumatic component; however, both methods have large omissions, resulting in the cap directions of some bottle caps cannot be corrected.

[0085] In this embodiment, visual monitoring is combined with mechanical rejection to reject bottle caps with the wrong orientation, and only bottle caps with the correct orientation are retained for further uploading; a monitoring component mobile frame 9 is set at a low position near the lifting climbing frame 1 and on the lifting climbing frame 1; a monitoring and rejection component is set on the monitoring component mobile frame 9; the monitoring and rejection component is used to capture and monitor the orientation of the passing caps, and to remove the caps with inconsistent orientations from the conveyor belt 2.

[0086] like Figure 9 As shown, the above-mentioned monitoring component mobile frame 9 is configured as an inverted "U"-shaped structure; the lower ends of the two vertical rods of the monitoring component mobile frame 9 are distributed on both sides of the lifting climbing frame 1, and the monitoring component mobile frame 9 spans the lifting climbing frame 1; the monitoring and rejection components are arranged on the cross bar of the monitoring component mobile frame 9.

[0087] like Figure 9 As shown, the above-mentioned monitoring and rejection components include: a high-speed capture camera 901, a slide rail 902, an electric-controlled slider 903, an electric-controlled telescopic rod 904 and a toggle arc plate 905;

[0088] A high-speed capture camera 901 is arranged in the middle of the horizontal bar of the monitoring component moving frame 9; a slide rail 902 is arranged below the horizontal bar of the monitoring component moving frame 9, and an electric-controlled slider 903 is movably arranged on the slide rail 902; the tail end of the electric-controlled telescopic rod 904 is arranged below the electric-controlled slider 903; a toggle arc plate 905 is arranged at the end of the telescopic section of the electric-controlled telescopic rod 904; the high-speed capture camera 901, the electric-controlled slider 903 and the electric-controlled telescopic rod 904 are all communicatively connected to the PLC.

[0089] When the conveyor belt 2 carries the lid and rises to the position directly below the high-speed capture camera 901, the high-speed capture camera 901 will capture the image of the lid opening direction on the conveyor belt 2 and feed the captured visual image information into the PLC. The PLC processes the visual image information. If it is identified that the lid opening is facing the conveyor belt, that is, the lid orientation is inconsistent, the PLC will locate the lid and send a control instruction to the electric control slider 903. The electric control slider 903 moves on the slide rail 902, driving the electric control telescopic rod 904 and the lower end of the toggle arc plate 905 to move together to the position of the lid orientation inconsistent, and then the electric control telescopic rod 904 extends to make the concave side surface of the toggle arc plate 905 fit on the side wall of the lid, and the concave side surface of the toggle arc plate 905 that contacts the side wall of the lid is provided with convex points 9051. These convex points 9051 are The cover is made of rubber, and a striped structure is usually provided on the side of the cover. The protrusions 9051 and the striped structure can increase friction. In this way, after the concave side of the movable arc plate 905 contacts the side wall of the cover, the electrically controlled telescopic rod 904 retracts. In this process, the cover and the movable arc plate 905 are subjected to friction, driving the cover to leave the surface of the conveyor belt 2, and finally falling from the plate 201 to be rejected. The motor controlling the conveyor belt 2 is controlled by the PLC, so that it stops for a period of time every time it conveys the distance between two plates 201. That is, whenever a plate 201 carrying a cover arrives under the monitoring and rejection component, the conveying is stopped, and the monitoring and rejection component will start the rejection operation. After completing the rejection operation, the conveying continues, and the cycle continues. The monitoring and rejection component will remove the cover facing in the opposite direction from the conveyor belt 2, and only retain the cover facing the correct direction to continue to be uploaded.

[0090] like Figure 1 As shown, as a preferred embodiment, in order to prevent the lid from rolling off the sides of the conveyor belt 2 during transportation, side bars 101 are provided on both sides of the lifting climbing frame 1; the coverage range of the side bars 101 starts from the bottom of the slide-out channel 4 and extends to the hopper 3; the side bars 101 on both sides are symmetrical.

[0091] Example 2

[0092] Based on Example 1, in Example 1, the strap 201 is fixedly arranged on the surface of the conveyor belt 2; the width of the strap 201 protruding from the surface of the conveyor belt 2 is fixed; however, the thickness of the lid used may be wider than the protruding width of the strap 201; resulting in the lid being unable to completely overlap the strap 201; thus, when the lid is conveyed on the strap 201, the lid may fall off the strap 201.

[0093] So, if Figure 8As shown, a strap 201 is detachably mounted on the surface of the conveyor belt 2. Several rows of protruding studs 202 are evenly spaced on the surface of the conveyor belt 2, with each row consisting of several equally spaced protruding studs 202. A number of equally spaced recessed slots 2011 are formed on the contact surface between the strap 201 and the conveyor belt 2.
