Description

Technical Field

[0001] The present invention relates to the technical field of vial conveying, and in particular to a conveying system and a conveying method for a vial visual inspection platform. Background Art

[0002] The vial, also known as the borosilicate glass tube injection bottle, is a small bottle sealed with a rubber stopper. It comes in brown, transparent and other types, and is generally made of glass. The neck of the vial is thinner, and the thickness below the neck is consistent. The mouth of the bottle is slightly thicker than the neck and slightly thinner than the bottle body. It is generally used as an antibiotic bottle, injection bottle, vaccine bottle, oral liquid bottle, etc. At present, the transportation of vials is completed by a conveyor belt, and the robot grabs the vial to the visual inspection station for inspection, and then puts it back on the conveyor belt for transmission after the inspection, which is inefficient. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a conveying system and a conveying method for a vial visual inspection platform, which can quickly move the vial between the conveying mechanism and the visual inspection station, thereby improving work efficiency.

[0004] In order to solve the above problems, the present invention adopts the following technical solutions:

[0005] A conveying system for a visual inspection platform for vials of the present invention comprises a conveying mechanism for conveying vials and a transfer mechanism arranged on the side of the conveying mechanism, wherein the transfer mechanism comprises a bracket, a rotating wheel and a first servo motor for driving the rotating wheel to rotate are arranged on the front side of the bracket, three supporting modules are arranged at equal intervals on the outer wall of the rotating wheel, the supporting modules comprise a bottle suction mechanism and rollers arranged on both sides of the bottle suction mechanism, a rotating wheel for driving the vials to rotate, a driving motor for driving the rotating wheel to rotate and a lifter for driving the rotating wheel to rise and fall are arranged above the rotating wheel, and vial grabbing mechanisms are arranged on the left and right sides of the rotating wheel.

[0006] In this technical solution, the three conveying modules on the rotating wheel face the rotating wheel and two vial grabbing mechanisms respectively.

[0007] The conveying mechanism conveys the vial forward. When the vial moves to the bottom of the first vial grabbing mechanism, the conveying mechanism stops conveying. The first vial grabbing mechanism grabs the vial below and places it on the front conveying module. The vial is sucked by the vial suction mechanism of the conveying module. Then the rotating wheel rotates 120 degrees, and the conveying mechanism conveys the next vial to the bottom of the first vial grabbing mechanism. After the rotating wheel rotates 120 degrees, the three conveying modules move accordingly, so that the components facing the three conveying modules change. The vial on the top conveying module comes to the visual inspection station, and the vial suction mechanism of the top conveying module releases the vial. The first vial grabbing mechanism continues to grab the next vial and place it on the front conveying module. The rotating wheel descends and contacts the vial on the top conveying module, driving the vial to rotate several times, so that the visual inspection device can detect whether there are any defects in the appearance of the vial and whether the dimensions specified by the standard are within the tolerance range. The second vial grabbing mechanism will move to the conveying module on its side and take the vial off and place it on the conveying mechanism.

[0008] The transfer mechanism and the conveying mechanism work closely together. The rotating wheel can detect a vial by rotating 120 degrees. The inspected vial is placed in front of the original conveying mechanism for further transportation, which greatly improves the detection efficiency.

[0009] Preferably, the conveying mechanism comprises a conveyor belt, on which a plurality of conveying blocks for supporting the vials are evenly arranged along the conveying direction.

[0010] Preferably, the conveying block is a V-shaped conveying block, which enables the vial to be stably placed transversely thereon, thus ensuring stable conveying operation.

[0011] Preferably, the bottle suction mechanism comprises a first suction nozzle, and the first suction nozzle is connected to the first vacuum mechanism, so as to suck the vial by vacuum suction to avoid damage to the surface of the vial caused by collision.

[0012] Preferably, the syringe bottle grabbing mechanism includes a grabbing rod and a driving mechanism for driving the grabbing rod, the grabbing rod includes a suction rod, a second suction nozzle is provided at the bottom end of the suction rod, and the top end of the suction rod is connected to the second vacuum mechanism.

[0013] Preferably, the driving mechanism includes a second servo motor, a motor mounting plate, a sliding mechanism, a rocker arm and a cam. The second servo motor, the motor mounting plate, the sliding mechanism, the rocker arm and the cam are arranged on the rear side of the bracket. The sliding mechanism and the cam are respectively located on both sides of the rocker arm. The grabbing rod is connected to the rotating shaft of the second servo motor through a connecting rod. The second servo motor is used to drive the grabbing rod to rotate. The sliding mechanism is tilted. The sliding mechanism includes a slider and a slide rail that cooperate with each other. The slider is fixed to the rear side of the bracket. The second servo motor is fixedly connected to the lower part of the motor mounting plate, and the upper part of the motor mounting plate is fixedly connected to the slide rail. The bottom of the rocker arm is rotatably connected to the bracket, the middle part of the rocker arm is abutted against the bottom end of the slide rail, and the top of the rocker arm is abutted against the cam. The driving mechanism also includes a driving cylinder for driving the cam to rotate.

[0014] The second servo motor drives the grabbing rod to rotate. The driving cylinder drives the cam to rotate, the cam drives the swing rod to swing, and the swing rod drives the slide rail to slide relative to the slider, thereby driving the second servo motor to tilt and move. The tilting movement of the second servo motor can drive the grabbing rod to move left and right in the horizontal direction and move up and down in the vertical direction. In conjunction with the rotation of the grabbing rod and the suction / deflation, the vials on the conveying mechanism can be grabbed and placed on the conveying module, and the vials on the conveying module can be grabbed and placed on the conveying mechanism.

[0015] Preferably, the bracket is provided with a through hole for the connecting rod to pass through, the through hole is oval in shape, and the setting direction of the through hole is consistent with the tilting movement direction of the grabbing rod.

[0016] Preferably, the driving mechanism further comprises a tension spring, one end of which is connected to the second servo motor, and the other end of which is fixedly connected to the bracket. When the cam rotates clockwise and does not apply thrust to the swing rod, the tension spring pulls the second servo motor to move downward, so that the grabbing rod can quickly return to its original position.

[0017] A vial conveying method of the present invention is used for the above-mentioned conveying system for a vial visual inspection platform, comprising the following steps:

[0018] The vial is transported forward by the conveying mechanism to the bottom of the first vial grabbing mechanism. The first vial grabbing mechanism grabs the vial below and places it on the bottle suction mechanism of the front conveying module. The bottle suction mechanism sucks the vial.

[0019] The rotating wheel rotates the vial to the top, the bottle suction mechanism releases the vial, the rotating wheel descends and contacts the vial, driving the vial to rotate several circles, so that the visual inspection device can detect whether there is any defect in the appearance of the vial;

[0020] The rotating wheel rises without contacting the vial, the bottle suction mechanism sucks the vial, the rotating wheel rotates the vial to the front and bottom, the second vial grabbing mechanism grabs the vial, the bottle suction mechanism releases the vial, the second vial grabbing mechanism places the vial on the conveying mechanism, and the conveying mechanism continues to convey the vial forward.

[0021] The beneficial effects of the present invention are as follows: (1) the vial can be quickly moved between the conveying mechanism and the visual inspection station, greatly improving the work efficiency. (2) the vial is grasped by vacuum suction during the entire conveying process, avoiding collision damage to the vial and scratching the surface of the vial. In particular, the length of the vial has little effect on the conveying system, greatly improving the stability and work efficiency of the inspection. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In this technical solution, the three conveying modules on the rotating wheel face the rotating wheel and two vial grabbing mechanisms respectively.

[0029] The conveying mechanism conveys the vial forward. When the vial moves to the bottom of the first vial grabbing mechanism, the conveying mechanism stops conveying. The first vial grabbing mechanism grabs the vial below and places it on the front conveying module. The vial is sucked by the vial suction mechanism of the conveying module. Then the rotating wheel rotates 120 degrees, and the conveying mechanism conveys the next vial to the bottom of the first vial grabbing mechanism.
