Description

Technical Field

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

[0002] A vial, also known as a borosilicate glass injection vial, is a small bottle sealed with a rubber stopper. It comes in brown and transparent colors 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 vial is slightly thicker than the neck and slightly thinner than the body of the bottle. It is generally used as an antibiotic bottle, an injection bottle, a vaccine bottle, an oral solution bottle, etc.

[0003] At present, the bottle discharging device generally used in the visual inspection platform for vials is to transport the vials to the inclined plate through the conveying mechanism, so that the vials roll along the inclined plate to the adjustment mechanism, and the adjustment mechanism adjusts the vials from the horizontal placement state to the vertical placement state, and then transports them to the collection device. The stability is poor and it is easy to cause bottle inversion and bottle jamming. When the qualified products inspected by the visual inspection system roll to the adjusted vertical state on the inclined plate, the friction between the vials and the adjustment mechanism causes cracks and white spots on the bottle surface, thereby generating secondary defects, making the product quality unguaranteed. Summary of the invention

[0004] In order to solve the above-mentioned technical problems, the present invention provides a bottle discharging device and a conveying system for a visual inspection platform for vials, which can stably and quickly convert vials placed horizontally on a conveying mechanism into a vertical placement state and transfer them to a collecting device, thereby improving work efficiency, and is less likely to cause bottle tipping, bottle jamming, and the like, while reducing the friction and collision between vials and equipment, thereby ensuring product quality.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions:

[0006] A bottle discharging device for a visual inspection platform for vials of the present invention comprises a conveying mechanism, an ejecting mechanism and a transfer mechanism, wherein the ejecting mechanism and the transfer mechanism are relatively arranged on the left and right sides of the conveying mechanism, the transfer mechanism comprises a placement block and a rotating cylinder for driving the placement block to rotate, the top surface of the placement block is provided with an arc groove penetrating the placement block from left to right, the arc groove is provided with a vacuum suction port, the vacuum suction port is connected to a vacuum generator, and the ejecting mechanism is used to push the vials on the conveying mechanism into the arc groove.

[0007] In this technical solution, the horizontally placed vials are transported to the ejection mechanism by the conveying mechanism, the ejection mechanism pushes the vials into the arc groove, the vacuum suction port sucks the vials, and the rotary cylinder drives the placement block to rotate 90 degrees to a vertical state. At this time, the distance between the bottom end of the placement block and the bottom surface of the collection device is very small, the vacuum suction port releases the vial, and the vial falls into the collection device and remains in a vertical state. The entire bottle discharging process is simple and fast, and it is not easy to cause bottle inversion or bottle jamming. At the same time, it reduces the friction and collision between the vial and the equipment, ensuring product quality.

[0008] Preferably, the conveying mechanism comprises a conveyor belt, on which a plurality of conveying blocks are evenly arranged along a conveying direction, and a top surface of the conveying block is provided with a V-shaped groove penetrating the conveying block from left to right.

[0009] Preferably, the lowest point of the arc-shaped groove and the lowest point of the V-shaped groove are at the same height.

[0010] Preferably, the ejection mechanism comprises an ejection block and an ejection cylinder for driving the ejection block to extend and retract.

[0011] Preferably, the transfer mechanism further comprises a conveyor belt, and when the placement block is rotated to a vertical state, the conveyor belt is located directly below the bottom end of the arc-shaped groove. The placement block places the vial on the conveyor belt, and the conveyor belt transports the vial to the collection device.

[0012] Preferably, the curvature of the arc-shaped groove matches the curvature of the body of the vial.

[0013] A conveying system for a visual inspection platform for vials of the present invention comprises the above-mentioned bottle discharging device for the visual inspection platform for vials.

[0014] Preferably, the conveying system for the visual inspection platform for syringe bottles further includes a transfer mechanism arranged on the side of the conveying mechanism, the transfer mechanism includes a bracket, a rotating wheel and a first servo motor for driving the rotating wheel to rotate are provided on the front side of the bracket, three supporting modules are evenly spaced on the outer wall of the rotating wheel, the supporting module includes a bottle suction mechanism and rollers arranged on both sides of the bottle suction mechanism, a rotating wheel for driving the syringe bottle to rotate, a driving motor for driving the rotating wheel to rotate and a lifter for driving the rotating wheel to lift are provided above the rotating wheel, and syringe bottle grabbing mechanisms are provided on the left and right sides of the rotating wheel.

[0015] The three conveying modules on the rotating wheel face the rotating wheel and the two vial grabbing mechanisms respectively. 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 conveying module in front. 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 is sent 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.

[0016] 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.

[0017] The beneficial effects of the present invention are as follows: (1) It is able to stably and quickly convert the vials placed horizontally on the conveying mechanism into a vertical placement state and transfer them to the collecting device, thereby improving work efficiency and making it less likely for the vials to fall over or get stuck, while reducing the friction and collision between the vials and the equipment, thereby ensuring product quality. (2) It is able to quickly convey the vials to the visual inspection station for inspection, and then quickly remove the vials, thereby shortening production time. (3) The conveying mechanism adopts a V-shaped conveying block, so that the length of the vials is not affected by the conveyor belt (the existing chain-type V-plate conveyor belt can generally only inspect vials longer than 30MM).

[0025] The transfer mechanism also includes a conveyor belt 10. When the placement block 2 is rotated to a vertical state, the conveyor belt 10 is located directly below the bottom end of the arc-shaped groove 4.

[0028] Embodiment 2: A conveying system for a vial visual inspection platform of this embodiment includes a bottle discharging device for a vial visual inspection platform described in Embodiment 1, such as Figure 2 , Figure 3 As shown, it also includes a transfer mechanism arranged on the side of the conveying mechanism 1, the transfer mechanism includes a bracket 11, a rotating wheel 12 and a first servo motor 13 for driving the rotating wheel 12 to rotate are provided on the front side of the bracket 11, three supporting modules 14 are evenly spaced on the outer wall of the rotating wheel 12, the supporting module 14 includes a bottle suction mechanism and rollers 15 arranged on both sides of the bottle suction mechanism, a rotating wheel 16 for driving the syringe bottle 31 to rotate, a driving motor 17 for driving the rotating wheel 16 to rotate, and a lifter 18 for driving the rotating wheel 16 to rise and fall are provided above the rotating wheel 12, and syringe bottle grabbing mechanisms are provided on the left and right sides of the rotating wheel 12.

[0029] In the present technical solution, the three conveying modules on the rotating wheel face the rotating wheel and the two vial grabbing mechanisms respectively. 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 conveying module in front. 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 is sent 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 the vial from the conveying module on its side and place it on the conveying mechanism. The conveying mechanism transports the vial to the ejection mechanism, and the ejection mechanism pushes the vial into the arc groove.

[0030] 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 and continued to be transported to the ejection mechanism, which greatly improves the detection efficiency.

[0031] The bottle suction mechanism comprises a first suction nozzle, which is connected to a first vacuum mechanism. The vial is sucked by vacuum suction to avoid damage to the surface of the vial caused by collision.

[0032] The grabbing mechanism for the vial includes a grabbing rod and a driving mechanism for driving the grabbing rod. The grabbing rod includes a suction rod 19. A second suction nozzle 20 is provided at the bottom end of the suction rod 19. The top end of the suction rod 19 is connected to a second vacuum mechanism.

[0033] The driving mechanism includes a second servo motor 21, a motor mounting plate 22, a sliding mechanism, a rocker arm 23 and a cam 24. The second servo motor 21, the motor mounting plate 22, the sliding mechanism, the rocker arm 23 and the cam 24 are arranged on the rear side of the bracket 11. The sliding mechanism and the cam 24 are respectively located on both sides of the rocker arm 23. The grabbing rod is connected to the rotating shaft of the second servo motor 21 through a connecting rod 30. The second servo motor 21 is used to drive the grabbing rod to rotate. The sliding mechanism is tilted. The sliding mechanism includes a slider 25 and a slide rail 26 that cooperate with each other. The slider 25 is fixed to the rear side of the bracket 11. The second servo motor 21 is fixedly connected to the lower part of the motor mounting plate 22, and the upper part of the motor mounting plate 22 is fixedly connected to the slide rail 26. The bottom of the rocker arm 23 is rotatably connected to the bracket 11, the middle part of the rocker arm 23 is abutted against the bottom end of the slide rail 26, and the top of the rocker arm 23 is abutted against the cam 24. The driving mechanism also includes a driving cylinder 27 for driving the cam 24 to rotate.

[0034] 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.

[0035] The bracket 11 is provided with a through hole 28 for the connecting rod 30 to pass through, and the through hole 28 is oval in shape. The setting direction of the through hole 28 is consistent with the tilting movement direction of the grabbing rod.

[0036] The driving mechanism also includes a tension spring 29, one end of which is connected to the second servo motor 21, and the other end of which is fixedly connected to the bracket 11. 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.

[0037] The process of conveying vials on this conveying system is as follows:

[0038] The horizontally placed vials are 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.

[0039] 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;

[0040] The rotating wheel rises and does not touch the vial, the bottle suction mechanism sucks the vial, the rotating wheel rotates to move 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 puts the vial on the conveying mechanism, and the conveying mechanism transports the vial to the ejecting mechanism;

[0041] The ejection mechanism pushes the vial into the arc-shaped groove, the vacuum suction port sucks the vial, and the rotary cylinder drives the placement block to rotate 90 degrees to a vertical state. At this time, the distance between the bottom of the placement block and the conveyor belt is very small. The vacuum suction port releases the vial, and the vial falls onto the conveyor belt and remains in a vertical state. The conveyor belt transports the vial to the collection device.
