Description

Technical Field

[0001] The invention relates to the technical field of condom production, in particular to a device for automatically detecting the front and back sides of a condom. Background Art

[0002] A condom is a sleeve-shaped diaphragm commonly used for contraception. Its production process includes raw material production, mold preparation, dipping and molding, curling and demolding, quality inspection, post-processing and packaging.

[0003] When condoms are produced, natural latex is first mixed into liquid and heated, then the glass mold is cleaned and dried, and then the glass mold is placed in the prepared natural latex, and then slowly pulled up so that the surface of the mold is evenly stained with milky white latex, dried, and a second gluing is performed to improve the sealing of the condom. The port of the condom is then curled with a roller brush for customer convenience. After that, the head of the condom is flushed with a high-pressure water column to make the condom fall off the mold. The condom is then cleaned with corn starch, cleaned and dehydrated by an industrial washing machine, and then dried. The condoms are then subjected to appearance inspection, size measurement, air tightness inspection, and electronic pinhole inspection. Lubricating oil and gas additives are then added, and the condoms are finally packaged.

[0004] After the condom quality inspection, the condom is curled and disordered. In order to ensure that the lubricant is added to the front of the condom, the front and back of the condom will be inspected. The existing front and back inspection of condoms is usually carried out manually. Since the condoms are of a single color, long-term inspection will cause eye fatigue and easy detection errors; Publication No. CN214348003U, by inflating the condom to make the condom expand and stretch, and then the stretched height is detected by a height sensor. When the front side is stretched, a part of the film will be rolled on the curling edge, so that the front stretch is lower than the back stretch height, thereby determining the front and back of the condom. The back side will be blown away from the inspection position by the blowing nozzle, and no manual inspection is required, but the back side of the condom requires workers to manually turn over the film, and bacteria are easily increased during the turning process, resulting in unqualified condom quality, which is time-consuming and labor-intensive.

A control mechanism 7 for controlling the opening and closing of the negative pressure pipe 12 is provided between the turntable 2 and the workbench 1. A connecting mechanism 21 communicated with 12, the connecting mechanism 21 passes through the turntable 2 and is connected with the support seat 3, the connecting mechanism 21 includes a sleeve 211 on the bottom surface of the support seat 3, one end of the sleeve 211 is fixedly connected to the turntable 2, a socket connected with the sleeve 211 is provided in the turntable 2, a sleeve 212 is movably inserted in the socket, a limit spring 213 is provided between the sleeve 1 211 and the sleeve 212, a through hole 31 communicated with the connecting mechanism 21 is provided on the support seat 3, a connecting mechanism 2 32 communicated with the through hole 31 is provided between the bearing component 4 and the support seat 3, and a column 22 is movably inserted on the turntable 2 at one side of the support seat 3.

[0034] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 3 As shown, the turntable 2 rotates to drive the condom on the supporting assembly 4 to move to the bottom of the detection mechanism 6, and the air blowing tube 11 blows air through the connecting mechanism 1 21, the through hole 31, and the connecting mechanism 2 32 in sequence to expand the condom, and the back condom will drive the detection mechanism 6, and the detection mechanism 6 drives the plug column 22 to move downward while driving the gear 41 to slide, and the plug column 22 drives the control mechanism 7 to make the back condom on the front side, and the flipping mechanism 8 drives the supporting assembly 4 to rotate by driving the gear 41 to rotate.

[0035] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 5 , Attachment Fig.14As shown, a clamping column 221 is movably inserted on the plug post 22 and a reset spring 222 is provided between the clamping column 221 and the plug post 22, a clamping groove cooperating with the clamping column 221 is provided on the turntable 2, an L-shaped reset rod 223 penetrating the plug post 22 is provided at one end of the clamping column 221, a cylinder 224 is provided on the plug post 22, an L-shaped driving rod 225 cooperating with the cylinder 224 is provided on the workbench 1, and a driving block 226 cooperating with the L-shaped reset rod 223 is provided on the L-shaped driving rod 225.

[0036] The working principle of the present invention is as follows: in the initial state, the limit spring 213 and the return spring 222 are in a compressed state, a condom is placed on the bearing assembly 4 from the feed slot 51, and then the motor drives the turntable 2 to rotate, the bearing assembly 4 moves away from the toggle rod 53, the bearing assembly 4 presses the condom, and then the turntable 2 moves to the detection mechanism 6, the limit spring 213 pushes the sleeve 212 to move downward and fit with one end of the blowing tube 11, and air is blown to expand the condom. Since the height of the front condom is low, the detection mechanism 6 and subsequent detection mechanisms will not be triggered. The control mechanism 7, the flip mechanism 8, and the reset mechanism 9 are then used to directly take out the condom from the discharge slot 52; when the condom is on the reverse side, the gas enters the connection mechanism 1 21, the through hole 31, and the connection mechanism 2 32 from the blowing tube 11, and the condom expands. Since the height of the condom on the reverse side is higher than that of the condom on the front side after expansion, the detection mechanism 6 is driven, and the detection mechanism 6 drives the plug post 22 to move downward. When the card column 221 on the plug post 22 moves to the card slot on the turntable 2, the reset spring 1 222 pushes the card column 221 to move and enter the card slot, and at the same time When the gear 41 is driven to slide away from the support seat 3, the turntable 2 continues to rotate, the sleeve 212 returns to the initial position, the limit spring 1 213 is compressed, and the plug 22 drives the control mechanism 7 during the movement, and the control mechanism 7 controls the closing cover 71 to open, and then the sleeve 212 is located above the negative pressure tube 12, and the limit spring 1 213 pushes the sleeve 212 to make it fit with the surface of one end of the negative pressure tube 12, so that the film of the reverse condom is turned down, and the reverse operation is completed at this time, and then the turntable 2 continues to rotate. When it passes through the flipping mechanism 8 When the gear 41 is rotated, the flip mechanism 8 drives the gear 41 to rotate, and the gear 41 drives the bearing assembly 4 to rotate. The driving block 226 first drives the L-shaped reset rod 223 to move, and the reset spring 222 is compressed, and the clamping column 221 moves away from the clamping slot. Then the L-shaped driving rod 225 drives the cylinder 224 to move upward, thereby driving the plug column 22 to move upward. Then, when passing through the discharge slot 52, the unloading mechanism 13 is started to take out the condom. At this time, the condom is facing forward and the direction of the film is the same as that of the front condom. Then the reset mechanism 9 resets the bearing assembly 4.

[0037] Combined with Figure 2 , Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 6 , Attachment Figure 7As shown, the bearing assembly 4 includes a frame 42 rotatably arranged on the support seat 3, and the frame 42 has a certain resistance when rotating. The gear 41 is slidably arranged at one end of the frame 42, and a fixed block 43 is provided on the frame 42. A placement groove 44 is provided on the fixed block 43, and a circular ring 45 for pressing the condom is hinged in the placement groove 44, and a torsion spring 46 is provided between the inner wall of the placement groove 44 and the circular ring 45. A slider 48 passing through the frame 42 is provided on the fixed block 43, and a connecting plate 47 is hinged at one end of the slider 48, and the other end of the connecting plate 47 is hinged to the circular ring 45. The connecting mechanism 2 32 includes a sleeve 3 321 on the bottom surface of the fixed block 43, and a sleeve 4 322 is movably inserted in the sleeve 3 321 and a limit spring 2 323 is provided between the sleeve 3 321 and the sleeve 3 321.

[0038] Working principle of the bearing assembly 4: In the initial state, the torsion spring 1 46 and the limit spring 2 323 are in a relaxed state. When the bearing assembly 4 is fitted with the toggle rod 53, the toggle rod 53 abuts against the slider 48 to move the slider 48 toward the fixed block 43. The slider 48 drives the connecting plate 47 to move, and the connecting plate 47 drives the ring 1 45 to rotate, and the torsion spring 1 46 is twisted. At this time, the condom is placed in the placement groove 44. When the bearing assembly 4 is away from the toggle rod 53, the torsion spring 1 46 drives the ring 1 45 to rotate and return to the initial state. The condom is compressed at the initial position, and the ring 1 45 drives the connecting plate 47 and the slider 48 to return to the initial position. When the bearing assembly 4 needs to be rotated, the sleeve 4 322 slides into the sleeve 3 321, the limit spring 2 323 is compressed, and the sleeve 4 322 is away from the through hole 31. The setting of the connecting mechanism 2 32 can realize the flipping of the bearing assembly 4 and limit the bearing assembly 4 at the same time. After the frame 42 is flipped, the frame 42 is limited by the friction between the frame 42 and the support seat 3 itself.

[0039] Combined with Figure 2 , Attachment Figure 3 , Attachment Figure 5 , Attachment Figure 7 , Attachment Figure 8 , Attachment Fig.11As shown, the detection mechanism 6 includes a square tube 61 arranged on the bottom surface of the top plate 5, a sliding plate 62 is slidably arranged in the square tube 61, and the sliding plate 62 is made of a light material. A limiting mechanism 64 for limiting the moving direction of the sliding plate 62 is provided on the square tube 61. An L-shaped connecting pipe 33 is provided on one side of the support seat 3, and the L-shaped connecting pipe 33 is located above the plug column 22 and fits the plug column 22. A connecting hole 34 connected to the through hole 31 is provided in the support seat 3, and the connecting hole 34 is connected to the L-shaped connecting pipe 33. There is a connecting hole 2 35 connected with the connecting hole 1 34 and the connecting hole 2 35 is in contact with one side of the gear 41. A sliding column 65 is slidingly arranged in the through hole 31 and passes through the support seat 3. A spring 1 66 is arranged between the sliding column 65 and the support seat 3. A baffle 1 67 for blocking the through hole 31 is arranged at one end of the sliding column 65. An L-shaped rod 68 is arranged on the bottom surface of the baffle 1 67. A baffle 2 69 for blocking the connecting hole 1 34 is arranged at one end of the L-shaped rod 68. A driving mechanism 610 is arranged on the support seat 3 for driving the sliding column 65 to move toward the direction of the support seat 3 by moving the sliding plate 62 upward.

[0040] Working principle: In the initial state, spring 1 66 is in a relaxed state. When it is a front condom, the expanded film will not contact the sliding plate 62, thereby not pushing the sliding plate 62 to move upward. When it is a back condom, one end of the condom film pushes the sliding plate 62 to move upward, and the sliding plate 62 can only move upward through the limiting mechanism 64. The upward movement of the sliding plate 62 drives the driving mechanism 610, and the driving mechanism 610 drives the sliding column 65 to move. The spring 1 66 is compressed, and the sliding column 65 drives the baffle 1 67 and the baffle 2 69 to move, so that the baffle 1 67 blocks the through hole 31, and the baffle 2 69 no longer blocks the connecting hole 1 34. The gas in the blowing tube 11 enters the connecting hole 1 34 and the connecting hole 2 35 instead of the through hole 31, pushing the plug 22 to move downward, and at the same time pushing the gear 41 away from the support seat 3.

[0041] Combined with Figure 5 , Attachment Figure 7 , Attachment Figure 8 As shown, the driving mechanism 610 includes an extension block 611 arranged at one end of the sliding plate 62 and passing through the square tube 61, a connecting rod 612 is hinged on the support seat 3 and a torsion spring 2 613 is provided between the connecting rod 612 and the support seat 3, one end of the connecting rod 612 is in contact with the extension block 611, a semicircular shell 614 is provided on the connecting rod 612, one end of the sliding column 65 is fitted with the semicircular shell 614, and a circular ring 2 615 is provided on the connecting rod 612 to cooperate with the slider 48.

[0042] Working principle: In the initial state, the torsion spring 613 is in a relaxed state, the sliding plate 62 moves upward to drive the extension block 611 to move upward, the extension block 611 drives the connecting rod 612 to rotate upward, the torsion spring 613 is twisted, and then the connecting rod 612 drives the sliding column 65 to move through the semicircular shell 614, and the attached Figure 7As shown, the end of the connecting rod 612 that fits the extension block 611 is farther away from the rotation point, so that only a smaller force is needed to push the other end of the connecting rod 612 . The second ring 615 is provided so as not to affect the rotation of the bearing assembly 4 .

[0043] Combined with Figure 8 , Attachment Fig. 9 , Attachment Fig.10 As shown, the limiting mechanism 64 includes pawls 641 slidably arranged on both sides of the sliding plate 62, and a return spring 642 is provided between the pawls 641 and the sliding plate 62, and a ratchet bar 643 cooperating with the pawls 641 is provided in the square tube 61.

[0044] Combined with Figure 8 , Attachment Fig. 9 , Attachment Fig.10 As shown, a reset plate 616 is slidably provided in the square tube 61, and a reset spring 63 is provided between the reset plate 616 and the bottom surface of the top plate 5, a reset rod 617 cooperating with a pawl 641 is provided on the bottom surface of the reset plate 616, and a driving hole 619 cooperating with the reset rod 617 is provided on the pawl 641, one end of the reset plate 616 extends to the outside of the square tube 61, and a top column 618 cooperating with the reset plate 616 is provided on the turntable 2.

[0045] Working principle: in the initial state, the reset spring three 642 is in a relaxed state. In the detection state, the top column 618 is against the bottom surface of the reset plate 616. At this time, the reset spring two 63 is in a compressed state, and the reset plate 616 does not move downward by a large margin. The sliding plate 62 moves upward, and the ratchet bar 643 squeezes the pawl 641 to make it slide away from the ratchet bar 643. The reset spring three 642 is compressed, and the pawl 641 cooperates with the ratchet bar 643 to make the sliding plate 62 only move upward. After the detection of a reverse condom is completed, the turntable 2 rotates to the next bearing component 4, and the top column 618 is separated from the reset plate 616. The reset spring two 63 pushes the reset plate 616 to move downward, and the reset rod 617 on the bottom surface of the reset plate 616 is inserted into the drive hole 619, so that the pawl 641 is away from the ratchet bar 643. At this time, the sliding plate 62 moves downward under the action of gravity to return to the initial position, thereby not affecting the next detection.

[0046] Combined with Figure 2 , Attachment Fig.12 , Attachment Fig.13As shown, the control mechanism 7 includes a closing cover 71 hinged on the workbench 1 and the closing cover 71 is fitted with one end of the negative pressure tube 12, a torsion spring 72 is provided between the closing cover 71 and the workbench 1, an arc gear 73 is provided on the closing cover 71, a rack 74 meshing with the arc gear 73 is movably inserted on the workbench 1, an L-shaped connecting rod 75 is provided on the rack 74 and one end of the L-shaped connecting rod 75 is movably inserted on the workbench 1, a driving plate 76 cooperating with the plug column 22 is provided on the L-shaped connecting rod 75, and the plug column 22 moves downward to abut against the driving plate 76 to move the driving plate 76 downward.

[0047] Working principle of control mechanism 7: in the initial state, torsion spring three 72 is in a relaxed state. When it is a reverse condom, detection mechanism 6 pushes plug post 22 to move downward. Plug post 22 first fits with driving plate 76 and moves driving plate 76 downward. Driving plate 76 moves downward and drives rack 1 74 to move downward. Rack 1 74 drives arc gear 73 to rotate. Arc gear 73 drives closing cover 71 to rotate and open closing cover 71. Then one end of sleeve two 212 fits with one end of negative pressure tube 12 to complete the flanging of the reverse condom.

[0048] Combined with Figure 2 , Attachment Figure 3 , Attachment Fig.14 , Attachment Fig.15 As shown, the flipping mechanism 8 includes a slide groove 81 on the workbench 1, a push block 82 is slidably provided in the slide groove 81 and a spring 83 is provided between the slide groove 81, an L-shaped push plate 84 is provided on the bottom surface of the turntable 2, a bar 85 is provided on the push block 82, a matching groove 86 matching with the L-shaped push plate 84 is provided on the bar 85, an L-shaped fixing rod 87 is provided on the bar 85, and a rack 88 is provided on the L-shaped fixing rod 87. The detection mechanism 6 pushes the gear 41 to move, so that the rack 88 engages with the gear 41 when the bearing assembly 4 moves to the flipping mechanism 8.

[0049] Working principle of the flip mechanism 8: In the initial state, the spring 2 83 is in a relaxed state. Fig.14 , the rotation direction of the turntable 2 is clockwise. When it is a reverse condom, the detection mechanism 6 drives the gear 41 to move away from the support seat 3. When the bearing assembly 4 approaches the flipping mechanism 8, the L-shaped push plate 84 on the turntable 2 pushes the bar 85, so that the push block 82 slides in the slide groove 81, and the spring 83 is compressed. At this time, the L-shaped fixed rod 87 is away from the bearing assembly 4, so as not to affect the movement of the bearing assembly 4 in the circumferential direction. When the bearing assembly 4 reaches the flipping mechanism 8, the L-shaped push plate 84 completely enters the matching groove 86, the spring 83 pushes the bar 85 to move, and the rack 88 on the L-shaped fixed rod 87 moves. The rack 88 drives the gear 41 to rotate, thereby driving the bearing assembly 4 to rotate.

[0050] Combined with Figure 1 , Attachment Figure 2 , Attachment Fig.16 As shown, the reset mechanism 9 includes a slide groove 91 on the workbench 1, a push block 92 is slidably provided in the slide groove 91 and a spring 93 is provided between the slide groove 91, an L-shaped push plate 94 is provided on the bottom surface of the turntable 2, a bar 95 is provided on the push block 92, a matching groove 96 matching with the L-shaped push plate 94 is provided on the bar 95, an L-shaped fixing rod 97 is provided on the bar 95, a rack 98 is provided on the L-shaped fixing rod 97, and an arc block 99 for pushing the gear 41 to slide is provided on the L-shaped fixing rod 97.

[0051] Working principle: In the initial state, spring three 93 is in a relaxed state. After the material is unloaded, the turntable 2 drives the rotating bearing component 4 to enter the reset mechanism 9. First, the L-shaped push plate two 94 on the turntable 2 pushes the bar two 95, so that the push block two 92 slides in the slide groove two 91, and the spring three 93 is compressed. When the bearing component 4 reaches the reset mechanism 9, the L-shaped push plate two 94 completely enters the matching groove two 96, and the spring three 93 pushes the bar two 95 to move, and the rack three 98 on the L-shaped fixed rod two 97 moves. The rack three 98 drives the gear 41 to rotate, thereby the bearing component 4 rotates. When the bearing component 4 returns to the initial position, the arc block 99 pushes the gear 41 back to the initial position.

[0052] Combined with Figure 1 , Attachment Figure 2 , Attachment Fig.16 As shown, the unloading mechanism 13 includes a mounting base 14 arranged on the workbench 1, a cylinder 15 is arranged on the mounting base 14, an L-shaped receiving plate 16 is arranged at the output end of the cylinder 15, and a push plate 17 cooperating with the slider 48 is arranged on the L-shaped receiving plate 16.

[0053] Working principle: When the flipped supporting component 4 reaches the discharge slot 52, the cylinder 15 is started, and the cylinder 15 drives the L-shaped receiving plate 16 to move. When the L-shaped receiving plate 16 is located below the placement slot 44, the push plate 17 pushes the slider 48 to move, so that the ring 145 releases the fixation of the condom, and the condom falls on the L-shaped receiving plate 16, and then the cylinder 15 outputs in the reverse direction, thereby unloading the condom on the reverse side.

[0054] In specific use, the condom is placed in the placement groove 44 at the feed groove 51, and then the turntable 2 rotates, the supporting component 4 is no longer in contact with the toggle rod 53, and the ring 45 presses the condom tightly. Then the turntable 2 drives the supporting component 4 to rotate to the detection mechanism 6, and the front and back sides of the condom are detected by the detection mechanism 6. When it is the front side, the height of the condom after expansion cannot contact the sliding plate 62, and the detection mechanism 6 is not triggered. The turntable 2 drives the supporting component 4 to the discharge groove 52, and then the condom is taken out. When it is the back side, the condom pushes the sliding plate 62 after expansion, thereby triggering the detection mechanism 6, driving the plug column 22 to move downward, and at the same time driving the gear 41 to slide away from the support seat 3, and then the plug column 22 triggers the control mechanism 7 to turn the condom, and the flipping mechanism 8 drives the gear 41 to rotate, thereby driving the supporting component 4 to rotate, and then the material is received by the L-shaped receiving plate 16, and finally the supporting component 4 is reset by the reset mechanism 9, thereby completing the detection of the front and back sides of the condom.

[0055] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
