Description

Technical Field

[0001] The present invention relates to the technical field of capsule production, and in particular to a seam integrity visual inspection system for a capsule automated processing production line. Background Art

[0002] Capsules are generally used to contain powders or granules that are irritating to the esophagus and gastric mucosa, or drugs that have a bad taste, are easy to volatilize, are easily decomposed by saliva in the mouth, and are easily inhaled into the trachea. In the capsule production process, two semi-cylindrical shells are generally docked to form a complete capsule, and the drug is stored in the inner cavity of the capsule. At this time, there will be a seam in the middle of the docked capsule. During capsule production, the integrity of the seam needs to be visually inspected.

[0003] When visually inspecting the integrity of the seam, visual inspection equipment is usually used to visually inspect the capsule using a camera. When the capsule is transported to the visual inspection equipment, the capsule is generally transported horizontally through a conveyor. When the capsule is transported to the visual inspection equipment, only one side of the capsule is facing the visual inspection equipment. During the inspection, it is convenient to inspect only one side of the capsule, and it is impossible to complete the inspection of the whole capsule at the same time, thereby reducing the adequacy of the visual inspection and reducing the inspection effect. Summary of the invention

[0016] The present invention has the following beneficial effects:

[0017] 1. In the seam integrity visual inspection system for the capsule automated processing production line, when the capsule is being conveyed, the capsule is sent between two rollers through the lower hopper. In the process of the roller driving the capsule to move, the engagement of the gear and the tooth plate can drive the roller to rotate, and the rotation of the roller drives the capsule to rotate, so that when the capsule reaches the visual inspection equipment, it can rotate, thereby facilitating the inspection of the capsule around one circle and increasing the adequacy of the inspection.

[0018] 2. In the seam integrity visual inspection system for the capsule automated processing production line, after the gear is meshed with the tooth plate, when the drum drives the capsule to rotate, the piston rod slides in the first slide groove, driving the first sliding protrusion to slide inside the first track groove, so that the piston rod can drive the suction plate to move inside the air cavity, so that negative pressure suction can be generated at the suction head. When the drum rotates and drives the suction head to rotate, the suction head can adsorb the capsule, thereby driving the capsule to rotate and lift the capsule. After the capsule rotates a certain angle, the suction head no longer generates negative pressure, causing the capsule to fall. When the capsule falls, the capsule can rotate along the surface of the drum, thereby facilitating the detection of one circle of the capsule. At the same time, the above-mentioned capsule rotation process can avoid damage to the capsule surface caused by the friction between the drum and the capsule when the capsule rotates, thereby improving the protection effect.

[0019] 3. In the seam integrity visual inspection system for the capsule automated processing production line, when the suction head absorbs and rotates the capsule, the suction plate can drive the air pipe to move through the connecting rod, and the movement of the air pipe drives the suction head to slide in the slideway, so that the suction head can drive the absorbed capsule to move horizontally, so that after the absorbed capsule moves, the accumulated capsule can fall between the two rollers for transportation, and when the suction head drives the absorbed capsule to move horizontally, the sliding bar slides in the second slide groove, driving the second sliding protrusion to slide inside the second track groove, so that the sliding bar can drive the suction head to rotate left and right by a certain angle through the driving component, so that the suction head drives the absorbed capsule to rotate left and right by a certain angle, so that a certain angle is formed between the accumulated capsule and the absorbed capsule, which is convenient for forming dislocation, and it is more convenient for the accumulated capsule to fall between the two rollers, which is convenient for subsequent visual inspection. In addition, when the suction head drives the absorbed capsule to rotate left and right, the visual inspection equipment can inspect both ends of the capsule, thereby increasing the adequacy of the inspection.

DETAILED DESCRIPTION

[0031] The following will be combined with the 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0032] For example, see Figure 1-Figure 10 , a seam integrity visual inspection system for an automated capsule processing production line comprises a fixed base 1, a conveyor frame 2 is fixed on the upper surface of the fixed base 1, a conveyor 3 is installed on the inner side of the conveyor frame 2, a roller 4 for conveying capsules is arranged on the inner side of the conveyor 3, a mounting frame 5 is fixed on the upper surface of the conveyor frame 2, a lower hopper 6 is fixed on the upper surface of the mounting frame 5, a transversely arranged partition 7 is fixed at the middle position of the mounting frame 5, and a visual inspection device 8 for detecting the seam integrity of capsules is fixed on the upper surface of the conveyor frame 2;

[0033] A rotating shaft 9 is fixed at both ends of the drum 4, and a gear 10 is fixedly connected to the end of the rotating shaft 9 at one end. A receiving groove 11 is provided inside the conveyor frame 2, and a tooth plate 12 for meshing with the gear 10 is fixed inside the receiving groove 11. The drum 4 rotates through the meshing of the gear 10 and the tooth plate 12, driving the capsule to rotate.

[0034] In the present technical solution, the feed hopper 6 is a prior art, which is used to feed the capsules, so that the length direction of the capsules is consistent with the length direction of the drum 4, and the capsules are arranged between the two drums 4 for transportation; the visual inspection device 8 is also a prior art, which is used to detect the integrity of the capsule seams through a camera. Since the feed hopper 6 and the visual inspection device 8 are prior art, they are not described in detail in this application;

[0035] When inspecting the integrity of the capsule seams, firstly, the capsules are unloaded through the unloading hopper 6 so that the capsules fall between the two rollers 4. The roller 4 moves with the conveyor 3 to move the capsules to the visual inspection device 8. When the roller 4 moves to the front end of the visual inspection device 8, the gear 10 is moved to the position of the gear plate 12 through the toothed plate 12 arranged inside the conveyor frame 2. The gear 10 engages with the toothed plate 12. After that, when the roller 4 continues to move with the conveyor 3, the gear 10 rotates. The rotation of the gear 10 drives the rotating shaft 9 to rotate. The rotation of the rotating shaft 9 drives the roller 4 to rotate. The rotation of the roller 4 causes the transported capsule to rotate, so that the visual inspection device 8 can complete the circumferential inspection of the capsule through the rotation of the capsule when performing the seam integrity inspection, thereby increasing the adequacy of the inspection.

[0036] In the second embodiment, in order to reduce the wear of the capsule caused by the rotation of the drum 4, the surface of the capsule and the surface of the drum 4 are generally smooth. When the drum 4 rotates and drives the capsule to rotate, the drum 4 may rotate but the capsule does not rotate, so that when the capsule is subjected to circumferential detection, the capsule cannot rotate one circle, thereby reducing the adequacy of the detection. To address this problem, this embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figure 1-Figure 10 The interior of the drum 4 is set as a hollow structure, and a plurality of groups of suction pipes 13 are set inside the drum 4. The outer surface of each group of suction pipes 13 is connected to a plurality of groups of suction heads 14 for adsorbing capsules. A suction assembly for generating negative pressure suction at the suction head 14 is set between the drum 4 and the conveyor frame 2. A plurality of groups of suction assemblies are set corresponding to the suction pipes 13, and the plurality of groups of suction assemblies move synchronously through the fixed rod 36.

[0037] The air suction assembly includes an air cavity 15 opened inside the drum 4, the air cavity 15 is connected to the air suction pipe 13, an air suction plate 16 is slidably arranged inside the air cavity 15, and both ends of the fixed rod 36 are respectively fixed between two adjacent groups of air suction plates 16;

[0038] A first slide groove 18 is provided inside the conveyor frame 2, a piston rod 17 is slidably provided in the first slide groove 18, a first track groove 19 is provided on the inner wall of the first slide groove 18, a first sliding protrusion 20 is fixed to the end of the piston rod 17, the first sliding protrusion 20 is slidably provided in the first track groove 19, and the other end of the piston rod 17 is rotatably connected to the nearest set of suction plates 16;

[0039] The first track groove 19 includes a horizontal portion 191, a first inclined portion 192 and a second inclined portion 193 which are sequentially connected;

[0040] A first one-way valve 21 is installed inside the suction head 14 , an air outlet 22 is provided on the drum 4 , and a second one-way valve 23 is installed inside the air outlet 22 .

[0041] In this technical solution, the initial position of the suction head 14 is as follows Figure 8 As shown, after the gear 10 is meshed with the toothed plate 12, when the gear 10 rotates to drive the drum 4 to rotate, the suction head 14 first rotates with the rotation of the drum 4, and the suction head 14 rotates from the initial state to position a, where a is the contact point between the capsule and the drum 4. When the suction head 14 is about to rotate to position a, the drum 4 drives the piston rod 17 to slide in the first sliding groove 18. At this time, the piston rod 17 drives the first sliding protrusion 20 to slide from the horizontal portion 191 of the first track groove 19 to the first inclined portion 192, and the first sliding protrusion 20 slides in the first inclined portion 192, as shown in FIG. Figure 5 As shown, the piston rod 17 moves to the left, and the piston rod 17 moves to the left to drive the air suction plate 16 to move to the left inside the air cavity 15. The air suction plate 16 is sealed with the air cavity 15, so that the air cavity 15 generates a negative pressure. The air cavity 15 sucks air from the inside of the air suction pipe 13, and the air suction pipe 13 uses the suction head 14 to suck air from the outside, so that a negative pressure is generated at the suction head 14. When the suction head 14 rotates to a, the suction head 14 adsorbs the capsule. The adsorption force generated at the suction head 14 is set in a suitable range, so that the capsule will not be damaged when the capsule is adsorbed;

[0042] like Figure 5 As shown, the above-mentioned suction components are arranged in several groups, and the suction plates 16 in two adjacent groups of suction components are connected by fixed rods 36, so that the suction plates 16 in each group can move synchronously, so that each group of suction components can perform synchronous suction work, so that the suction of capsules by each group of suction heads 14 does not affect each other, even if there is no suction capsule on one group of suction heads 14, it will not affect the suction work of the other group of suction heads 14 on the capsule;

[0043] The first sliding protrusion 20 continues to slide inside the first inclined portion 192. Figure 6As shown, until the first sliding protrusion 20 slides to the leftmost end of the first inclined portion 192, the suction head 14 rotates from a to b, and the suction capsule adsorbed by the suction head 14 also rotates to b, and then the first sliding protrusion 20 slides along the second inclined portion 193, so that the first sliding protrusion 20 drives the piston rod 17 to move right, and the piston rod 17 moves to the right to drive the suction plate 16 to move to the right, and the suction plate 16 moves to the right, so that negative pressure adsorption is no longer generated at the suction head 14, and the capsule will fall from the suction head 14 at b. Since the angle at b is within 45 degrees of the circumference of the drum 4, when the capsule falls from the suction head 14 at b, the capsule moves downward due to its own gravity, so that the capsule moves downward along the surface of the drum 4, and when moving downward, it will rotate along the surface of the drum 4, thereby realizing the rotation of the capsule, so that the capsule can rotate at least one circle, and when the visual inspection equipment 8 performs seam integrity inspection, the capsule can be fully inspected for one circle, further improving the adequacy of the inspection.

[0044] In the present technical solution, by setting the first one-way valve 21 and the second one-way valve 23, the first one-way valve 21 allows the suction head 14 to only inhale but not blow, and the second one-way valve 23 allows the air outlet 22 to only exhaust but not inhale; when the piston rod 17 moves to the left, the first one-way valve 21 is opened and the second one-way valve 23 is in a closed state, so that the suction head 14 performs negative pressure adsorption of the capsule; when the piston rod 17 moves to the right, the first one-way valve 21 is closed and the second one-way valve 23 is opened, so that the gas is discharged from the air outlet 22, so that the suction head 14 will not blow, thereby preventing the blown gas from affecting the rotation of the capsule.

[0045] In the third embodiment, when the material is discharged from the discharge hopper 6, a small amount of capsules may be accumulated in one place (at most two places). If the capsules are adsorbed by the suction head 14 to the position b and fall down, the accumulated capsules will resist the falling capsules, so that the adsorbed capsules cannot complete the falling and rotating action, thereby affecting the subsequent visual inspection work. To solve this problem, this embodiment is an improvement made on the basis of the second embodiment. For details, please refer to Figure 1-Figure 10 A connecting rod 24 is fixed between the suction plate 16 and the suction pipe 13, the suction pipe 13 is slidably arranged inside the drum 4, and a slideway 25 for the suction head 14 to slide is provided on the drum 4;

[0046] The suction pipe 13 is connected with a connecting pipe 26, and a disc 27 is fixed to the end of the connecting pipe 26. The end of the suction head 14 is rotatably connected to the disc 27. The inside of the drum 4 is provided with a driving component for driving the suction head 14 to rotate.

[0047] The driving assembly includes a slide bar 28, a second slide groove 29 for the slide bar 28 to slide is provided in the drum 4, a first hinge seat 30 is fixed to the end of the slide bar 28, a rotating plate 31 is fixed to the outer surface of the suction head 14, a second hinge seat 32 is fixed to the rotating plate 31, a transmission rod 33 is rotatably connected between the first hinge seat 30 and the second hinge seat 32, a second track groove 34 is provided on the inner wall of the second slide groove 29, a second sliding protrusion 35 is fixed to the end of the slide bar 28, and the second sliding protrusion 35 is slidably arranged in the second track groove 34;

[0048] The second track groove 34 includes a first rising portion 341 , a descending portion 342 , and a second rising portion 343 which are sequentially connected and arranged.

[0049] In this technical solution, when the drum 4 rotates from a to b, Figure 5 As shown, the suction plate 16 drives the suction pipe 13 to move leftward through the connecting rod 24, so that the suction pipe 13 slides inside the drum 4, and the suction pipe 13 moves leftward and drives the suction head 14 to move leftward, so that the suction head 14 slides leftward along the slideway 25, and the suction head 14 slides leftward and drives the adsorbed capsules to move leftward, so that the adsorbed capsules and the capsules accumulated here are misaligned, which not only makes the adsorbed capsules fall and rotate, but also makes the accumulated capsules fall between the two groups of drums 4 after the capsules move, so as to avoid the accumulation of capsules before visual inspection;

[0050] When the suction head 14 slides to the left, the slide bar 28 is driven to slide to the left along the second slide groove 29. Fig.10 As shown, the slide bar 28 slides leftward along the second slide groove 29, driving the second sliding protrusion 35 to slide along the second track groove 34. First, the second sliding protrusion 35 slides along the rising portion, so that the second sliding protrusion 35 drives the slide bar 28 to move upward, and the upward movement of the slide bar 28 drives the transmission rod 33 to move upward. Since the two ends of the transmission rod 33 are rotatably connected with the first hinge seat 30 and the second hinge seat 32, the transmission rod 33 can pull the rotating plate 31 to rotate upward, and the rotating plate 31 rotates upward to drive the suction head 14 to rotate a certain angle, so that the suction head 14 can drive the capsule to move horizontally. When the capsule rotates a certain angle, there is a certain angle between the accumulated capsule and the adsorbed capsule, which is convenient for forming dislocation, so that the accumulated capsule can be more convenient to enter between the drums 4, and the capsules can be prevented from being piled up before visual inspection, thereby further improving the adequacy of inspection;

[0051] When the slide bar 28 continues to slide inside the second slide groove 29, the second sliding protrusion 35 slides along the descending portion 342, so that the slide bar 28 moves downward. First, before the second sliding protrusion 35 slides to half of the descending portion 342, the suction head 14 rotates in the opposite direction, so that the suction head 14 drives the adsorbed capsule to return to a horizontal state. Then, the second sliding protrusion 35 continues to slide along the descending portion 342, so that the adsorbed capsule rotates in the opposite direction by a certain angle. Then, the second sliding protrusion 35 slides along the second ascending portion 343 again, so that the adsorbed capsule returns to a horizontal state again. At this time, the drum 4 rotates to position b, and the adsorbed capsule falls from the suction head 14, completing the falling rotation and realizing the overturning.

[0052] In summary, when the roller 4 rotates from a to b, the suction head 14 can move horizontally in the slideway 25, driving the adsorbed capsule to move. At the same time, when the adsorbed capsule moves, the slide bar 28 slides in the second slide groove 29, driving the second sliding protrusion 35 to slide inside the second track groove 34, which can drive the suction head 14 to rotate left and right, thereby driving the adsorbed capsule to rotate left and right, so that there is a certain angle between the adsorbed capsule and the stacked capsule, which is convenient for forming a misalignment, so that it is more convenient for the stacked capsule to enter between the two rollers 4 for transportation. In addition, when the adsorbed capsule rotates left and right, the two ends of the capsule are lifted, so that the visual inspection device 8 can detect defects at both ends of the capsule, thereby facilitating the inspection of the end of the capsule;

[0053] When doing specific work, such as Figure 1 As shown, first, the lower hopper 6 delivers the capsule to the surface of the drum 4 below the partition 7 for conveying. When the capsule conveying position exceeds the partition 7, the gear 10 is meshed with the tooth plate 12, and the drum 4 starts to rotate. The capsule is driven to move to the surface of the drum 4 above the partition 7 through the movement of the suction head 14, thereby increasing the length of the drum 4 that can accommodate the capsule, so that the accumulated capsules can easily fall between the two drums 4 (there are at most two places where the capsules are accumulated). Figure 6 As shown, there are four groups of first inclined portions 192 and second inclined portions 193 in the first trajectory groove 19, and after the gears 10 are meshed with the gears 10, the gears 10 can rotate at least four times, so that when the drum 4 rotates four times, it can drive the capsules to perform four suction and discharge processes, thereby effectively avoiding the accumulation of capsules between detections, and at the same time, facilitating the rotation and turning over of the capsules during detection.

[0054] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
