DETAILED DESCRIPTION
[0035] The present invention is further described in detail below in conjunction with the accompanying drawings.
[0036] Combined with Figure 1 and attached Figure 2 As shown, a feeding device for pen holders comprises a frame 1, on which a feeding mechanism 2, a discharging mechanism 4 and a transfer mechanism 5 are arranged, and also comprises a driving frame 3, a displacement mechanism 6 and a feeding mechanism 7. The frame 1 comprises a base 11, on which a protective frame 12 is arranged. The feeding mechanism 2 comprises a feeding box 21 and a discharging ramp 27. The feeding box 21 is rotatably arranged in the protective frame 12. The pen holders in the feeding box 21 are arranged on the discharging mechanism 4 via the discharging ramp 27. The discharging mechanism 4 moves laterally on the driving frame 3. The frame 1 also comprises a vertical frame 16 and a horizontal beam 17. The horizontal beam 17 connects the vertical frame 16 and the protective frame 12. The transfer mechanism 5 moves laterally on the horizontal beam 17. The transfer mechanism 5 transfers the pen holders on the discharging mechanism 4 to the feeding mechanism 7, and the feeding mechanism 7 sends the pen holders to the conveyor belt.
[0037] Combined with Figure 2 , Attachment Figure 7 and attached Figure 8 As shown, the discharging mechanism 4 includes two transfer frames 41 and two arranging frames 42. A connecting shaft 412 is connected between the two transfer frames 41. The two arranging frames 42 are hinged to the connecting shaft 412. The arranging frames 42 are provided with equal length arranging grooves 422. The length of the arranging grooves 422 on the two arranging frames 42 after merging is the same as the length of the pen holder. The discharging mechanism 4 also includes a lifting platform 43 and a transmission rod 44. The lifting platform 43 is located between the transfer frames 41. The two sides of the top of the lifting platform 43 are respectively hinged to the transmission rod 44. The transmission rods 44 on both sides are respectively hinged to the bottom of the two arranging frames 42. The bottom of the transfer frame 41 and the lifting platform 43 are respectively provided with a slider 422. 411 and slider 2 431, the driving frame 3 includes a fixed slide 31, a fixed frame 15 connected to the fixed slide 31 is provided on the base 11, a slide groove 311 slidably matched with the slider 1 411 and the slider 2 431 is provided on the fixed slide 31, the fixed slide 31 is fixed on the base 11, a threaded rod 2 33 is rotatably provided on the top of the fixed slide 31, a motor 32 for driving the threaded rod 2 33 to rotate is provided on the base 11, threaded holes matching with the threaded rod 2 33 are provided on the transfer frame 41 and the connecting shaft 412, the shifting mechanism 6 drives the arranging frame 42 to rotate, and the transfer mechanism 5 clamps and transfers the upper part of the pen barrel on the rotated arranging frame 42.
[0038] The working principle of the driving frame 3 and the discharge mechanism 4 is as follows: the motor three 32 drives the threaded rod two 33 to rotate, driving the transfer frame 41 and the arranging frame 42 to slide on the fixed slide 31. When the arranging frame 42 moves from the discharge ramp 27 to the feeding mechanism 7, the discharge ramp 27 transports the pen holder to the combined arranging groove 422. After the arranging frame 42 reaches the top of the shifting mechanism 6, the lifting platform 43 is driven downward by the shifting mechanism 6, and the two arranging frames 42 are driven to rotate synchronously by the transmission rod one 44 on both sides, and the rotation angle is the same. At this time, the combined arranging groove 422 is separated from the middle. Since one end of the pen holder is open and the other end is closed, the center of gravity of the pen holder is close to the closed end. In the process of rotating with the arranging frame 42, the pen holder automatically falls into the arranging groove 422 at the closed end, presenting that the pen holders on both sides are in a state of open ends facing upwards, and then the pen holders in this state are clamped by the transfer mechanism 5 to complete the arrangement of the open ends of the pen holders.
[0039] Combined with Figure 1 , Attachment Figure 3 , Attachment Fig. 9 and attached Fig.10As shown, the transfer mechanism 5 includes a moving platform 51 slidably arranged on the crossbeam 17 and a clamp 54. The bottom of the moving platform 51 is provided with a cylinder 1 52 and a cylinder 2 53. The clamp 54 includes a hinge shaft 541. Two outer connecting rods 542 are hinged at both ends of the hinge shaft 541. A clamping shaft 543 and a transmission shaft 544 are connected between the outer connecting rods 542 on the same side. A rubber sleeve 545 is sleeved on the outer side of the clamping shaft 543. The output end of the cylinder 1 52 is provided with a rubber sleeve 545 connected to the hinge shaft 541. A lifting block 521 is connected, and a lifting block 531 is provided at the output end of the cylinder 53. A transmission rod 532 is hingedly connected between the lifting block 531 and the two transmission shafts 544. A slide rail 511 is provided on one side of the moving platform 51. A groove that slides with the slide rail 511 is provided on the crossbeam 17. A threaded rod 19 is provided in the groove. A motor 18 is provided on the stand. The output end of the motor 18 is connected to the threaded rod 19. The slide rail 511 is provided with a threaded hole that cooperates with the threaded rod 19.
[0040] Working principle of the transfer mechanism 5: motor 18 drives threaded rod 19 to rotate, and threaded rod 19 cooperates with threaded holes on slide rail 511 to make the transfer mechanism 5 move on the crossbeam 17. During clamping, cylinder 1 52 and cylinder 2 53 synchronously drive the clamp 54 to move downward. After reaching the position, cylinder 2 53 pushes lifting block 2 531 to move downward, and is transmitted through transmission rod 2 532 to drive the outer connecting rods 542 on both sides to rotate synchronously, so that the clamping shaft 543 is close, and the clamping points are located on both sides of the intersection of the pen shafts on both sides. The friction force on the pen shaft is increased by rubber sleeve 545, and then cylinder 1 52 and cylinder 2 53 synchronously drive the clamp 54 to move upward. During the upward movement, the pen shaft becomes vertical after being separated from the arrangement groove 422 due to gravity and the deformation ability of rubber sleeve 545. Then the transfer mechanism 5 moves to the top of the feeding mechanism 7 to transfer the pen shaft to the feeding mechanism 7.
[0041] Combined with Figure 7 and attached Fig. 9 As shown, the displacement mechanism 6 includes a cylinder three 61 and a driving platform 62. The cylinder three 61 is fixed on the base 11. The output end of the cylinder three 61 is connected to the bottom of the driving platform 62. The base 11 is provided with a directional slide 14 that slides with the driving platform 62. The top of the driving platform 62 extends into the bottom groove of the fixed slide 31. The fixed slide 31 is provided with a limiting beam 312 that limits the driving platform 62. The top of the driving platform 62 is provided with a slide groove 2 621 corresponding to the slide groove 1 311. The slide groove 2 621 slides with the slider 1 411 and the slider 2 431. The driving platform 62 drives the lifting platform 43 to move downward.
[0042] Working principle of the shifting mechanism 6: After the discharging mechanism 4 moves to the top of the shifting mechanism 6, the slider 2 431 slides into the slide groove 2 621, and the slider 1 411 is located in the slide groove 1 311. Then the cylinder 3 61 drives the driving platform 62 to move downward, and drives the lifting platform 43 to move downward through the slide groove 2 621, finally realizing the synchronous rotation effect of the two arrangement frames 42.
[0043] Combined with Figure 1 , Attachment Figure 6 and attached Figure 7 As shown, a baffle 275 is hingedly provided at the discharge port at the bottom of the discharging ramp 27, driving rods 277 are hingedly provided on both sides of the baffle 275, side baffles 276 that cooperate with the driving rod 277 are provided on both sides of the baffle 275, a limiting plate 272 that cooperates with the baffle 275 and a fixed plate 273 are provided above the bottom of the discharging ramp 27, a spring 274 connected to the baffle 275 is provided at the bottom of the fixed plate 273, an outer shaft platform 278 is provided on the outer side of the bottom of the driving rod 277, and a guide slide 421 that cooperates with the outer shaft platform 278 is provided at the side groove on the top of the arranging frame 42.
[0044] Working principle of the discharge ramp 27: Under normal conditions, the spring 274 pushes the baffle 275 toward the discharge port at the bottom of the discharge ramp 27 to block the discharge of the pen holder. When the arrangement frame 42 moves toward the direction of the feed mechanism 2, the outer shaft platform 278 is blocked by the guide slide 421, causing the drive rod 277 to rotate in the direction away from the side baffle 276, and the baffle 275 will not open, and no discharge action will occur. When the arrangement frame 42 moves from the feed mechanism 2 to the shifting mechanism 6, the outer shaft platform 278 is blocked by the guide slide 421, causing the drive rod 277 to rotate in the opposite direction, and the drive rod 277 pushes the side baffle 276 to make the baffle 275 rotates until the baffle 275 contacts the limit plate 272, and the pen holder can fall from the discharge port at the bottom of the discharge ramp 27. At this time, the bottom height of the baffle 275 is between the top height of the pen holder on the arranging frame 42 and the top height of the pen holder after it falls into the arranging groove 422, so that after the pen holder falls into the arranging frame 42, the baffle 275 can stop the pen holder from moving until the pen holder falls into the arranging groove 422, and the pen holders are allowed to fall into the arranging grooves 422 in sequence. After the outer shaft platform 278 leaves the guide slide 421, the baffle 275 is reset. During the reset process, the pen holder that falls on the arranging frame 42 at the exit is pushed back into the discharge ramp 27.
[0045] Combined with Figure 1 and attached Figure 4As shown, the guard frame 12 on both sides of the feed box 21 is respectively rotatably provided with two single-end eccentric shafts 22 and two double-end eccentric shafts 23, and the eccentric shafts at one end of the single-end eccentric shaft 22 and the double-end eccentric shaft 23 are both rotatably connected to the feed box 21, and the guard frame 12 is rotatably provided with a driving wheel 25 and a connecting rod 24 on one side of the double-end eccentric shaft 23, and the eccentric shafts on the outer sides of the two double-end eccentric shafts 23 are respectively rotatably connected to the two ends of the connecting rod 24, and a connecting round table 241 is provided on the outer side of the connecting rod 24, and the connecting round table 241 is rotatably matched with the through hole at the eccentric position on the inner side of the driving wheel 25, and a groove wheel 1 251 is coaxially connected to one side of the driving wheel 25, and a groove wheel 2 281 is provided at the output end of the motor 28, and the groove wheel 1 251 and the groove wheel 2 281 are matched through belt transmission.
[0046] Working principle of the feed box 21: Motor 28 drives groove wheel 2 281 to rotate, groove wheel 1 251 cooperates with groove wheel 2 281 through belt transmission, drives the driving wheel 25 to rotate, and drives the linkage rod 24 to maintain vertical rotation through the through hole at the eccentric position on the inner side of the connecting table 241 and the driving wheel 25, and drives the feed box 21 to maintain vertical rotation through the transmission of the double-ended eccentric shaft 23, thereby moving the pen holder inside the feed box 21 to prevent the pen holder from getting stuck at the shrinkage of the inclined plate and causing blockage.
[0047] Combined with Figure 3 , Attachment Figure 4 and attached Figure 5 As shown, a push plate 211 is slidably provided in the through hole at the rear inclined plate of the feed box 21, a guide frame 212 is provided at the rear side of the push plate 211, a guide plate 13 is provided on the guard frame 12 and vertically slides with the guide frame 212, a material transfer plate 26 is vertically slidably provided at the bottom of the feed box 21, a smooth platform 271 is provided on the top of the discharge inclined platform 27 and horizontally slides with the material transfer plate 26, and the through hole at the center of the material transfer plate 26 is connected to the feed box 21 and corresponds to the feed port at the top of the discharge inclined platform 27.
[0048] Working principle of the push plate 211 and the transfer plate 26: In order to further improve the smoothness of pen discharge, a through hole is opened at the inclined plate on the rear side of the feed box 21, and a push plate 211 is set to move up and down with the feed box 21. The push plate 211 is stationary in the left and right directions. During the rotation of the feed box 21, the push plate 211 moves left and right relative to the feed box 21 to realize the pushing effect at the shrinkage of the inclined plate, and the inclined surface of the push plate 211 is used to push the pen holder in the left and right directions to the front and back directions, and finally falls into the through hole of the transfer plate 26. The transfer plate 26 moves left and right on the smooth platform 271 as the feed box 21 rotates. When the transfer plate 26 moves to the inlet position of the discharge inclined platform 27, the pen holder in the transfer plate 26 falls into the discharge inclined platform 27.
[0049] Combined with Figure 1 , Attachment Fig.11 , Attachment Fig.12 and attached Fig.13 As shown, the feeding mechanism 7 includes a support frame 71, an outer bracket 711 is provided on the support frame 71, a feeding plate 74 is rotatably provided at the end of the outer bracket 711, a motor 75 is provided on the support frame 71 for driving the feeding plate 74 to rotate, a plurality of placement grooves 741 for placing pen rods are provided on the feeding plate 74, a rod entry hole 742 is provided at the bottom of the placement groove 741, a cylinder 72 is provided on the support frame 71, a transverse plate 721 is provided at the output end of the cylinder 72, a plurality of push rods 73 are provided on the transverse plate 721, an orienting plate 712 is provided on the outer bracket 711, a plurality of through holes that slide with the push rods 73 are provided on the orienting plate 712, when the feeding plate 74 is laid flat, the push rod 73 passes through the rod entry hole 742 to push the pen rod toward the conveyor belt, and a material box 76 is provided at the bottom of the feeding plate 74.
[0050] The working principle of the feeding mechanism 7 is as follows: after the transfer mechanism 5 moves to the top of the feeding mechanism 7, it drives the pen shaft to move downward and places the pen shaft into the placement groove 741. Then the placement groove 741 drives the feeding plate 74 to rotate to a horizontal state. The cylinder four 72 pushes the transverse plate 721 to move, so that multiple push rods 73 slide in the through hole of the directional plate 712 and extend into the placement groove 741. The push rod 73 will push the closed end of the pen shaft and push the pen shaft from the placement groove 741 to the conveyor belt. If a pen shaft is in a different direction from other pen shafts, the push rod 73 will extend into the inside of the pen shaft from the open end of the pen shaft and will not push the pen shaft to move to the conveyor belt, further ensuring the consistency of the direction of the pen shafts on the conveyor belt. Then the push rod 73 is reset, and the feeding plate 74 rotates in the same direction, so that the pen shafts with different directions fall into the material box 76, and then the feeding plate 74 is reset.
[0051] During the specific implementation of the present invention, the pen holders are randomly poured into the feed box 21. The feed box 21 is rotated to make the pen holders in the feed box 21 face in a unified direction, and the pen holders are transported to the arrangement slots 422 through the discharge ramp 27. The discharge action of the discharge ramp 27 is realized along with the left and right lateral movement of the discharge mechanism 4. After the discharge mechanism 4 moves to the top of the shifting mechanism 6, the shifting mechanism 6 drives the two arrangement frames 42 to rotate synchronously. The principle that the center of gravity of the pen holder is biased toward the closed end is utilized to make the open end of the tilted pen holder face upward. Subsequently, the transfer mechanism 5 clamps the pen holder and transfers it to the feed plate 74. The feed plate 74 rotates to change the vertical pen holder to the horizontal direction, and the pen holder is pushed onto the conveyor belt through the push rod 73.
