Description

Technical Field

[0001] This utility model relates to the field of vial production technology, specifically to a contactless vial packaging device. Background Technology

[0002] Currently, the packaging of vials uses a compression method, where each product is pushed into the inner box one by one. During the pushing and squeezing process, the outside of the vials is easily scratched (the stress point on the shoulder of the vial is easily scratched), which leads to product defects. At the same time, the compression packaging is fast, and it is impossible for one person to operate multiple machines, thus preventing the effective reduction of product manufacturing costs. Summary of the Invention

[0003] In order to overcome the shortcomings of the above-mentioned technologies, this utility model provides a device to prevent product scratches during the packaging of vials and to improve packaging efficiency.

[0004] The technical solution adopted by this utility model to overcome its technical problem is: A contactless vial packing device includes: The frame has a flexible conveyor line at its upper end along the front-to-back direction. The flexible conveyor line is used to transport the vials produced on the vial production line from the front end to the back end. The turntable is rotatably mounted on the frame via the main shaft, which is set vertically. The turntable is located at the side end of the flexible conveyor line. N limit frames are evenly distributed on the turntable along the circumferential direction with the axis of the main shaft as the center. N is a positive integer greater than or equal to 2. The limit frames are provided with slots that match the shape of the inner packaging box of the vial. The inner packaging box is placed in the slot. A turntable drive unit, mounted on the frame, is used to drive the turntable to rotate; The bracket is fixed vertically to the machine frame, and a slide rail is horizontally installed at the upper end of the bracket in the left-right direction, with the slide block slidably mounted on the slide rail; and The slide drive mechanism, mounted on the bracket, is used to drive the slide to slide left and right along the slide rail; The vial pickup device is installed at the lower end of the slide via a transverse and longitudinal movement mechanism. When the slide slides to one side of the flexible conveyor line, the longitudinal movement mechanism drives the vial pickup device to move downward and pick up a row of vials on the flexible conveyor line. When the slide slides to one side of the turntable, the longitudinal and transverse movement mechanisms drive the vial pickup device to place the rows of vials alternately into the inner packaging box.

[0005] Furthermore, the aforementioned flexible conveyor line includes rotating shafts respectively mounted on the front and rear sides of the frame, a power unit for driving the rotating shafts to rotate, and the front and rear ends of the conveyor belt with a ring structure are respectively wrapped around the corresponding rotating shafts on the same side.

[0006] Furthermore, the aforementioned power unit includes a worm gear reducer I mounted on the frame. The output shaft of the worm gear reducer I is connected to a rotating shaft, and its input shaft is coaxially connected to a speed-regulating motor.

[0007] Furthermore, N is set to 5, and the turntable drive device includes a worm gear reducer II mounted in the frame. The output shaft of the worm gear reducer II is coaxially connected to the lower end of the main shaft, and its input shaft is coaxially connected to the output shaft of the servo motor II.

[0008] Furthermore, the aforementioned slide drive mechanism includes wheel seats respectively installed at the left and right ends of the slide rail, a synchronous pulley rotatably installed in the wheel seats, and a servo motor I installed on the bracket. The output shaft of the servo motor I is coaxially connected to a synchronous pulley. The left end of the synchronous belt passes over the synchronous pulley at the left end and is fixed to the left end of the slide. The right end of the synchronous belt passes over the synchronous pulley at the right end and is fixed to the right end of the slide.

[0009] To improve stability, a lower support arm is also included at the head end of the slide rail. The lower support arm is equipped with a seated bearing, and the upper end of the main shaft is rotatably mounted in the seated bearing.

[0010] Furthermore, the aforementioned vial pickup device includes a horizontally arranged rack along the front-to-back direction and a vacuum pump mounted on the frame. Several vacuum suction cups are spaced apart along the front-to-back direction on the rack, and each vacuum suction cup is connected to the vacuum pump through an air pipe.

[0011] Furthermore, the aforementioned longitudinal movement mechanism is cylinder II, the axis of which is arranged in the vertical direction, and the tail end of cylinder II is fixed on the slide.

[0012] Furthermore, the aforementioned transverse mechanism is cylinder III, the axis of which is horizontally arranged in the front-to-back direction. Cylinder III is fixed to the piston rod head of cylinder II, and the frame is fixed to the piston rod head of cylinder III.

[0013] To facilitate the discharge of vials in a row, the system includes a baffle plate located at the upper end of the conveyor belt and cylinder I mounted on the frame. The baffle plate is positioned along the front-to-back direction, with arc-shaped guide plates at both ends. Cylinder I is located above the conveyor belt, with its axis horizontally positioned along the left-to-right direction. A positioning plate is located at the piston rod end of cylinder I. When the piston rod of cylinder I is fully retracted, the positioning plate is positioned above the conveyor belt and at the side end of the baffle plate, with the last vial on the conveyor belt contacting the positioning plate. When the piston rod of cylinder I is fully extended, the positioning plate moves to the outside of the conveyor belt.

[0014] The beneficial effects of this invention are as follows: When the vials are arranged in a row, the slide drive mechanism moves the slide to one side of the flexible conveyor line. The longitudinal movement mechanism drives the vial picking device to move downwards. After the vial picking device picks up the row of vials, the longitudinal movement mechanism drives the vial picking device to move upwards. Then, the slide drive mechanism drives the slide to one side of the turntable. The slide drive mechanism drives the slide to move downwards again, placing the row of vials into the inner packaging box at the packaging station. The picking device then releases its grip on the vials. This non-contact vial packing device can be installed on both sides of a worker, allowing one person to operate two packing machines, improving production efficiency and reducing worker labor costs. Because the vials are packed vertically, there is no surface scratching due to friction, thus improving product quality. Attached Figure Description

[0016] The following is in conjunction with the appendix Figure 1 To be continued Figure 4 The present invention will be further described below.

[0017] A contactless vial packaging device includes: a frame 1 with a flexible conveyor line arranged along the front-to-back direction at its upper end, the flexible conveyor line being used to transport vials 11 produced on the vial production line from the front end to the rear end; a turntable 8, rotatably mounted on the frame 1 via a main shaft 29, the main shaft 29 being arranged vertically, the turntable 8 being located at the side end of the flexible conveyor line, and N limiting frames 9 being evenly distributed around the axis of the main shaft 29 along the circumferential direction, where N is a positive integer greater than or equal to 2, and the limiting frames 9 being provided with slots matching the shape of the inner packaging box 10 of the vial, the inner packaging box 10 being placed in the slots; and a turntable drive device, disposed on the frame 1, for driving the turntable 8 to rotate. A bracket 4 is fixed vertically to the frame 1. A slide rail 5 is horizontally arranged on the upper end of the bracket 4 in the left-right direction, and a slide block 22 is slidably installed on the slide rail 5. A slide block drive mechanism is set on the bracket 4 to drive the slide block 22 to slide left and right along the slide rail 5. A vial pick-up device is installed on the lower end of the slide block 22 through a transverse and longitudinal mechanism. When the slide block 22 slides to one side of the flexible conveyor line, the longitudinal mechanism drives the vial pick-up device to move downward and pick up a row of vials 11 on the flexible conveyor line. When the slide block 22 slides to one side of the turntable 8, the longitudinal and transverse drive mechanisms drive the vial pick-up device to place the rows of vials 11 alternately in the inner packaging box 10. The flexible conveyor line transports the vials 11 produced by the vial production line one by one from right front to back. The turntable drive device drives the turntable 8 to rotate to the innermost end of the packaging box (the position closest to the flexible conveyor line), which is the packaging station. When all the vials 11 are arranged in a row, the slide drive mechanism drives the slide 22 to move to one side of the flexible conveyor line. The longitudinal movement mechanism drives the vial picking device to move down. After the vial picking device picks up the row of vials 11, the longitudinal movement mechanism drives the vial picking device to move up. Then, the slide drive mechanism drives the slide 22 to move to one side of the turntable 8. The slide drive mechanism drives the slide 22 to move down again, placing the row of vials 11 into the packaging box 10 at the packaging station. The picking device then releases its fixation on the vials 11. The above steps are repeated to pick up the second row of vials 11. The difference is that after the second row of vials 11 is picked up, the lateral movement mechanism drives the vial picking device to move laterally a certain distance before placing the second row of vials 11 into the inner packaging box 10 at the packaging station. This achieves an alternating arrangement of the second row of vials 11 with the first row of vials 11. Subsequent rows of vials 11 are also placed alternately to meet packaging requirements. When an inner packaging box 8 is full of vials, the turntable drive device rotates the turntable 8, moving the next empty inner packaging box 8 to the packaging station. The worker then removes the inner packaging box 8 filled with vials 11 from the limiting frame 11.One contactless cartoning device of this utility model can be set on each of the left and right sides of a worker, so that one person can operate two cartoning machines, which improves production efficiency and reduces the labor efficiency of employees. Since the vials 11 are all packaged in a vertical position, they will not be scratched due to friction, thus improving the quality of the product.

[0018] In one embodiment of this utility model, the flexible conveyor line includes rotating shafts 12 respectively rotatably mounted on the front and rear sides of the frame 1, a power unit for driving the rotating shafts 12 to rotate, and a conveyor belt 3 with an annular structure having its front and rear ends respectively wrapped around the corresponding rotating shafts 12 on the same side. The power unit drives the rotating shafts 12 to rotate, and since the conveyor belt 3 is wrapped around the two rotating shafts 12, the conveyor belt 3 achieves a circular motion, conveying the vials 11 produced on the vial production line from the front end to the rear end. In this embodiment, the power unit includes a worm gear reducer I 13 mounted on the frame 1. The output shaft of the worm gear reducer I 13 is drivenly connected to a rotating shaft 12, and its input shaft is coaxially drivenly connected to a speed-regulating motor 14. The speed-regulating motor 14 drives the rotating shaft 12 connected to it to rotate, thereby causing the conveyor belt 3 to move in a circular motion. The speed-regulating motor 14 can easily change its speed, thereby facilitating the adjustment of its conveying speed to the vials 11 and making it easier to adjust the production line's cycle time.

[0019] In one embodiment of this utility model, N is set to 5, and setting 5 limiting frames 9 can maximize the efficiency of packaging vials 11. The turntable drive device includes a worm gear reducer II 27 installed in the frame 1. The output shaft of the worm gear reducer II 27 is coaxially connected to the lower end of the main shaft 29, and its input shaft is coaxially connected to the output shaft of the servo motor II 28. When the servo motor II 28 is activated, the torque is reduced and amplified by the worm gear reducer II 27 to drive the turntable 8 to rotate. The servo motor II 28 can achieve precise positioning, thereby ensuring that the turntable 8 rotates at a fixed angle, so that the corresponding limiting frame 9 rotates to the packaging station. The worm gear reducer II 27 has a self-locking characteristic. When the servo motor II 28 stops rotating, the turntable 8 will not rotate freely, thereby ensuring that the limiting frame 9 in the packaging station remains fixed, improving the reliability of use.

[0020] In one embodiment of this utility model, the slide drive mechanism includes wheel seats 20 respectively installed at the left and right ends of the slide rail 5, synchronous pulleys rotatably installed in the wheel seats 20, and a servo motor I 19 installed on the bracket 4. The output shaft of the servo motor I 19 is coaxially connected to a synchronous pulley. The left end of the synchronous belt 21 is fixed to the left end of the slide 22 after passing over the synchronous pulley at the left end, and the right end of the synchronous belt 21 is fixed to the right end of the slide 22 after passing over the synchronous pulley at the right end. The servo motor I 19 drives the synchronous pulley connected to it to rotate. Since the left and right ends of the synchronous belt 21 are respectively wrapped around the corresponding synchronous pulleys, the synchronous belt 21 achieves a circular motion. The two ends of the synchronous belt 21 are connected to the left and right ends of the slide 22, thereby driving the slide 22 to slide left and right along the slide rail 5.

[0021] In one embodiment of this utility model, a lower support arm 6 is further provided at the head end of the slide rail 5, and a seated bearing 7 is installed on the lower support arm 6. The upper end of the main shaft 29 is rotatably installed in the seated bearing 7. By providing the seated bearing 7, the upper end of the main shaft 29 is given additional support, the rigidity of the main shaft 29 is improved, and the reliability of the equipment operation is enhanced.

[0022] In one embodiment of this invention, the vial pickup device includes a horizontally arranged rack 25 along the front-to-back direction and a vacuum pump 2 mounted on a frame 1. A plurality of vacuum suction cups 26 are spaced apart along the front-to-back direction on the rack 25, and each vacuum suction cup 26 is connected to the vacuum pump 2 via an air pipe. When the vacuum pump 2 operates, it generates a vacuum suction force on the vacuum suction cups 26 through the air pipe, thereby allowing each vacuum suction cup 26 on the rack 25 to pick up the vials 11 arranged in a row on the flexible conveyor line. Each vacuum suction cup 26 picks up one vial 11, therefore the number of vacuum suction cups 26 is equal to the number of vials 11 arranged in a row.

[0023] In one embodiment of this utility model, the longitudinal movement mechanism is cylinder II 23, with its axis arranged vertically and its tail end fixed to the slide block 22. The transverse movement mechanism is cylinder III 24, with its axis arranged horizontally in the front-to-back direction. Cylinder III 24 is fixed to the piston rod head of cylinder II 23, and the frame 25 is fixed to the piston rod head of cylinder III 24. When the piston rod of cylinder II 23 extends outward, it pushes cylinder III 24 to move the frame 25 downward. When the piston rod of cylinder II 23 retracts inward, it pushes cylinder III 24 to move the frame 25 upward, thus achieving longitudinal movement. When the piston rod of cylinder III 24 extends outward, it drives the frame 25 to move horizontally in the front-to-back direction, achieving transverse displacement of the rows of vials 11.

[0024] In one embodiment of this utility model, a baffle 15 disposed on the upper end of the conveyor belt 3 and a cylinder I 18 mounted on the frame 1 are also included. The baffle 15 is disposed along the front-back direction, and arc-shaped guide plates 16 are respectively disposed at the front and rear ends of the baffle 15. The cylinder I 18 is located above the conveyor belt 3, and the axis of the cylinder I 18 is horizontally disposed along the left-right direction. A positioning plate 17 is disposed at the piston rod head of the cylinder I 18. When the piston rod of the cylinder I 18 is fully retracted, the positioning plate 17 is located above the conveyor belt 3 and at the side end of the baffle 15. The vial 11 at the last end of the conveyor belt 3 is in contact with the positioning plate 17. When the piston rod of the cylinder I 18 is fully extended, the positioning plate 17 moves to the outside of the conveyor belt 3. The arc-shaped guide plate 16 guides the vials 11 conveyed by the conveyor belt 3 to the baffle 15. The vials 11 rest against the baffle 15 and are conveyed to the rear end, ensuring that all vials are arranged in a row. Due to the function of the positioning plate 17, the last vial 11 is immobilized after contacting the positioning plate 17, and the subsequent vials 11 are pressed against each other, achieving a tight row. When there are vials 11 on the conveyor belt 3 that have not been picked up, the piston rod of cylinder I 18 extends to push the positioning plate 17 out of the conveying area of ​​the conveyor belt 3. At this time, the conveyor belt 3 starts and can continue to convey the unpicked vials 11 to the rear end, preventing them from lingering on the conveyor belt 3.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
