Description

Technical Field

[0001] The present invention relates to plastic parts packaging equipment, in particular to a plastic parts sorting, arranging and conveying mechanism and a packaging machine. Background Art

[0002] Plastic parts (such as disposable plastic forks used in catering) are generally processed and formed by injection molding equipment during the processing. One piece is processed at a time and then transferred to the packaging machine for packaging. Only a single piece of plastic part can be injected and packaged at a time, which is very inefficient. In view of this, we propose a plastic part material distribution and transmission mechanism and a packaging machine. Summary of the Invention

[0003] The main purpose of the present invention is to provide a plastic parts distribution and arrangement transmission mechanism and a packaging machine to solve the problem proposed in the related art that the existing equipment can only complete the injection molding and packaging of a single plastic part at a time, which is very inefficient.

[0004] To achieve the above objectives, according to one aspect of the present invention, a plastic part distribution and transport mechanism is provided, comprising a conveying portion and a material taking mechanism, wherein the conveying portion is used to convey a single plastic part, and the material taking mechanism is used to obtain an integral plastic part after injection molding, wherein the integral plastic part is composed of multiple single plastic parts arranged at equal distances around the circumference and integrally molded by an injection molding machine, and further comprising: The splitting and arranging mechanism is used to receive the whole plastic part obtained by the material taking mechanism and split the whole plastic part into several single plastic parts, and place each single plastic part at equal intervals in the same arrangement direction on the conveying part to be conveyed to the next process.

[0005] Furthermore, the splitting and arranging mechanism includes at least a first placement tray, a second placement tray and a transfer mechanism, wherein the first placement tray is used to receive the integral plastic parts from the material picking mechanism, and the transfer mechanism is used to transfer the integral plastic parts from the first placement tray to the second placement tray.

[0006] Furthermore, the center of the second placement plate is a second central cone, and a circle of placement holes is provided on the periphery of the second central cone. The placement holes pass through the second placement plate and can accommodate a single plastic part to pass through.

[0007] Furthermore, the second placement tray is driven to rotate intermittently by a driving component, and a discharge tray is provided under the second placement tray to fit with it. The discharge tray is stationary, and when the second placement tray rotates, all the single plastic parts are driven to rotate on the discharge tray through the placement holes.

[0008] Furthermore, a discharge hole is provided on the discharge tray, and the discharge hole is located directly above the conveying portion. The discharge hole can accommodate a single plastic part and is located at the same circumferential position as any placement hole.

[0009] Furthermore, a separation component is installed on the transfer mechanism, and the separation component is used to disassemble the entire plastic part into single plastic parts. A clamping part is installed on the separation component, and the clamping part is used to press down the entire plastic part. When the clamping part presses the entire plastic part, the downward pressure drives the bottom end of the clamping part to rotate to align the entire plastic part to the placement hole.

[0010] Furthermore, the transfer mechanism is installed on the machine body through a horizontal moving mechanism, and the horizontal moving mechanism is used to drive the transfer mechanism to move back and forth above the first placement tray and the second placement tray.

[0011] Furthermore, a removal component is installed on the transfer mechanism, and the removal component is used to remove waste materials of the disassembled integral plastic parts.

[0012] Furthermore, a material trough and a guide groove at one end of the material trough are provided above the conveying part. The guide groove is a V-shaped structure, and the large end of the V-shaped structure of the guide groove is located directly below the discharge hole.

[0013] Another aspect of the present invention provides a packaging machine equipped with any one of the above-mentioned plastic parts sorting, arranging and conveying mechanisms, and the packaging machine is also used to package single plastic parts conveyed by the conveying part.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention uses a horizontal moving mechanism to quickly transfer the entire plastic part between the two placement trays, and uses a splitting and arranging mechanism to split the entire plastic part into multiple single plastic parts and transport them to the conveyor belt. This can ensure that the single plastic part is normally transported backward while also having a limiting effect on the single plastic part, so that it will not be deviated, achieving the effect of automatic sorting and transmission, without the need for manual sorting, and is transported to the packaging machine behind it via the conveyor belt for packaging. During the entire process, the injection molding and packaging of multiple plastic parts can be completed in a single time, greatly improving the processing efficiency.

[0021] The present application provides a plastic part discharging and arranging transmission mechanism, which comprises a conveying part and a taking mechanism, the conveying part is used for conveying single plastic parts, and the taking mechanism is used for obtaining integral plastic parts after injection molding, the integral plastic parts are arranged at equal intervals in a circle by a plurality of single plastic parts, and the integral plastic parts are integrally injection molded by an injection molding machine.

[0022] Embodiment 1: In embodiment 1, the integral plastic part is an integral plastic fork 7.

[0023] Specifically, Example 1 provides a plastic part distribution and transmission mechanism, including a conveying portion and a material taking mechanism, wherein the conveying portion is used to convey a single plastic fork 71, and the material taking mechanism is used to obtain the whole plastic fork 7 after injection molding, wherein the whole plastic fork 7 is composed of multiple single plastic forks 71 arranged at equal distances around the circumference and integrally injection molded by an injection molding machine, and further comprising: The splitting and arranging mechanism is used to receive the whole plastic fork obtained by the material taking mechanism and split the whole plastic fork into several single plastic forks, and place the single plastic forks at equal intervals in the same arrangement direction on the conveying part to be conveyed to the next process.

[0024] like Figure 10 The figure shows an integral plastic fork 7, which is composed of a plastic fork connecting ring 72 formed by injection molding at the center and single plastic forks 71 connected to the plastic fork connecting ring 72 during the injection molding process and distributed at equal intervals around the circumference.

[0025] like Figure 9 As shown, the material taking mechanism includes a suction disc 81, which is located above the first placement disc 2, and a plurality of vacuum adsorption tubes 82 with circumferentially equal intervals are fixedly installed at the bottom end of the suction disc 81, and a suction disc connecting frame 83 is provided above the suction disc 81. The suction disc connecting frame 83 and the suction disc 81 are rotatably connected by rotating a rotating shaft provided at the end of the suction disc connecting frame 83, and a third motor 84 is fixedly installed on the suction disc connecting frame 83, and the output shaft and the rotating shaft of the third motor 84 are coaxially fixed, and a fourth cylinder 85 for pushing it up and down is fixed on the top of the suction disc connecting frame 83, as shown in FIG. Figure 1 As shown, a discharge guide rail 9 is provided on one side of the discharge mechanism 8 , and the discharge mechanism 8 is movably arranged on the discharge guide rail 9 .

[0026] The vacuum adsorption tube 82 and the vacuum adsorption component 48 are connected through a pipe and an air pump. The air pump sucks air to form a negative pressure in the vacuum adsorption tube 82 and the vacuum adsorption component 48 so that the plastic fork can be adsorbed. The air pump inflates the vacuum adsorption tube 82 and the vacuum adsorption component 48 to release the negative pressure and release the plastic fork.

[0027] The suction tray 81 adsorbs the single plastic fork 71 and the plastic fork connecting ring 72 through the vacuum adsorption tube 82 thereon, and transfers them to the top of the first placement tray 2 through free movement on the discharge guide rail 9. The suction tray 81 and the plastic fork thereon are pushed down by the fourth cylinder 85 to fit on the first placement tray 2, and the vacuum adsorption of the vacuum adsorption tube 82 is released, and the single plastic fork 71 and the plastic fork connecting ring 72 are discharged onto the first placement tray 2. At this time, the plastic fork connecting ring 72 is located on the first central cone 21, and each single plastic fork 71 is located in the corresponding placement groove 22. Then the fifth cylinder 16 drives the first placement tray bracket 17 and the first placement tray 2 on it to move down to fit on the surface of the transfer table 1 and stop.

[0028] In actual use, since the lowering distance of the discharge robot arm composed of the fourth cylinder 85 and the suction plate connecting frame 83 is insufficient, the fifth cylinder 16 is provided to drive the first placement plate bracket 17 to first push the first placement plate 2 upward to receive the entire plastic fork 7.

[0029] like Figure 1 、 Figure 2 、 Figure 7 and Figure 11 As shown, the splitting and arranging mechanism includes at least a first placing tray 2, a second placing tray 6 and a transfer mechanism 4. The first placing tray 2 and the second placing tray 6 are installed on the transmission platform 1 and are located on the same straight line. The first placing tray 2 is used to receive the integral plastic fork 7 from the material picking mechanism, and the transfer mechanism 4 is used to transfer the integral plastic fork from the first placing tray 2 to the second placing tray 6.

[0030] like Figure 5 As shown, the center of the first placement plate 2 is a first central cone 21, and a circle of placement grooves 22 are provided on the periphery of the first central cone 21. The top notch of the placement groove 22 is open and the bottom end is closed, which is used to place the integral plastic fork 7. The first placement plate bracket 17 is fixed below the first placement plate 2, and a fifth cylinder 16 that can drive it to move up and down is provided on one side of the first placement plate bracket 17. The fifth cylinder 16 is fixedly installed inside the transfer platform 1.

[0031] like Figure 6 As shown, the center of the second placement plate 6 is a second central cone 61 , and a circle of placement holes 62 is provided on the periphery of the second central cone 61 . The placement holes 62 pass through the second placement plate 6 and can accommodate a single plastic fork 71 to pass through.

[0032] like Figure 8As shown, the second placing tray 6 is driven to rotate intermittently by a driving component, and a discharge tray 14 is provided under the second placing tray 6 to fit therewith. The discharge tray 14 is stationary. When the second placing tray 6 rotates, all the single plastic forks 71 are driven to rotate on the discharge tray 14 through the placing holes 62; the discharge tray 14 is fixed inside the conveying platform 1, and the second placing tray 6 is rotatably installed inside the conveying platform 1 through a support shaft.

[0033] like Figure 8 As shown, the driving component includes a second motor 10 fixedly installed inside the transmission platform 1, and a second synchronous pulley 11 is coaxially fixedly installed on the output shaft end of the second motor 10. A third synchronous pulley 13 is provided on one side of the second synchronous pulley 11 and is located on the same plane as the second synchronous pulley. The third synchronous pulley 13 and the second synchronous pulley 11 are connected to each other through a second synchronous toothed belt 12, and the third synchronous pulley 13 and the second placement disk 6 are fixed.

[0034] like Figure 8 As shown, a discharge hole 15 is opened on the discharge tray 14 , and the discharge hole 15 is located directly above the conveying portion. The discharge hole 15 can accommodate a single plastic fork 71 and is located at the same circumferential position as any placement hole 62 .

[0035] like Figure 2 As shown, the transfer mechanism 4 is installed on the machine body through the horizontal moving mechanism 3, and the horizontal moving mechanism 3 is used to drive the transfer mechanism 4 to move back and forth above the first placement tray 2 and the second placement tray 6.

[0036] like Figure 3 As shown, the horizontal moving mechanism 3 includes a horizontal moving guide rail 31, and the horizontal moving guide rail 31 is fixedly installed on the transmission platform 1 through a plurality of guide rail support columns 32 arranged at the bottom end thereof. A first motor 33 is fixedly installed at one end of the horizontal moving guide rail 31, and a first synchronous pulley 34 is coaxially fixedly provided at the output shaft end of the first motor 33. The other end of the horizontal moving guide rail 31 is also rotatably installed with a first synchronous pulley 34 through a rotating shaft, and a first synchronous toothed belt 35 is meshed and connected between the two first synchronous pulleys 34. A first cylinder mounting slide 36 is fixedly mounted on the first synchronous toothed belt 35, and a first cylinder 37 and a vertical movable guide rail 38 are fixedly mounted on the first cylinder mounting slide 36 in parallel. A transfer mechanism mounting support 39 is slidably mounted on the vertical movable guide rail 38, and the piston rod end of the first cylinder 37 is fixed by a connecting block and the transfer mechanism mounting support 39; starting the first motor 33 drives the first synchronous pulley 34 to rotate, thereby driving the first synchronous toothed belt 35 to rotate, and then driving the first cylinder mounting slide 36 and the transfer mechanism 4 thereon to move along the horizontal movable guide rail 31.

[0037] like Figure 4 As shown, the transfer mechanism 4 is mounted on a transfer mechanism mounting bracket 39; the transfer mechanism 4 includes a second cylinder 41 and a third cylinder 46, both of which are fixed to the transfer mechanism mounting bracket 39. The end of the piston rod of the second cylinder 41 is fixedly connected to a cylinder connecting bracket 42, and the end of the cylinder connecting bracket 42 is fixedly connected to a pressure plate connecting bracket 43.

[0038] like Figure 4 As shown, a separation assembly is installed on the transfer mechanism 4, and the separation assembly is used to disassemble the entire plastic fork 7 into individual plastic forks 71. A pressing portion is installed on the separation assembly, and the pressing portion is used to press down and compress the entire plastic fork 7. The separation assembly includes an extrusion limit ring 44 fixedly connected to the end of the pressure plate connecting bracket 43 and a connecting ring extrusion column 45 fixed to the center of the pressure plate connecting bracket 43. The connecting ring extrusion column 45 passes through the middle of the extrusion limit ring 44. An ultrasonic transducer 18 is fixedly installed inside the transfer platform 1 at a position opposite the connecting ring extrusion column 45. The ultrasonic transducer 18 is facing and in contact with the second central cone 61.

[0039] When the transfer mechanism 4 moves to the top of the first placement plate 2, the second cylinder 41 is started to drive the extrusion limit ring 44 and the connecting ring extrusion column 45 to move up, and then the first cylinder 37 is started to push the transfer mechanism mounting bracket 39 to move down along the vertical moving guide rail 38 to the vacuum adsorption member 48 close to the single plastic fork 71 and the plastic fork connecting ring 72, and then the third cylinder 46 is started to push the vacuum adsorption member 48 to move down, so that the vacuum adsorption member 48 is attached to the surface of the plastic fork connecting ring 72, and the plastic fork connecting ring 72 and the single plastic fork 71 thereon can be adsorbed and fixed by the vacuum adsorption member 48, and then the transfer mechanism is pushed by the first cylinder 37. The mounting support 39 and the entire transfer mechanism 4 move upward, and the first synchronous toothed belt 35 drives the transfer mechanism 4 to move in the opposite direction to just above the second placement plate 6. The first cylinder 37 pushes the transfer mechanism 4 and the plastic fork connecting ring 72 and the single plastic fork 71 thereon downward again, and places the plastic fork connecting ring 72 and the single plastic fork 71 on the second center truncated cone 61 and the placement hole 62 of the second placement plate 6 respectively, and inflates the vacuum adsorption component 48 to release the adsorption of the plastic fork connecting ring 72 and the single plastic fork 71. The third cylinder 46 drives the vacuum adsorption component 48 to move upward, and then pushes the extrusion limit ring 44 and the connecting ring 72 through the second cylinder 41. The connecting ring extrusion column 45 moves downward, and the connecting ring extrusion column 45 contacts the plastic fork connecting ring 72 located in the center. The extrusion limiting ring 44 contacts all the single plastic forks 71 and forms a downward extrusion on the single plastic fork 71. The ultrasonic transducer 18 can generate ultrasonic vibration. Under the vibration of the ultrasonic wave, the water outlet at the connection between the plastic fork connecting ring 72 and the single plastic fork 71 will break, thereby separating the two. During the separation process, due to the existence of the extrusion limiting ring 44, the dispersed single plastic fork 71 is prevented from being confused due to ultrasonic vibration, and the whole plastic fork 7 is disassembled into single plastic forks 71. Since the second placement tray 6 and the discharge tray 14 are close to each other, Therefore, the separated single plastic forks 71 will not fall immediately. Only one of the single plastic forks 71 will fall from the placement hole 62 first and fall onto the conveyor belt 51 through the discharge hole 15 opposite to the placement hole 62. At the same time, the second motor 10 is started to drive the second synchronous pulley 11 to rotate, and the third synchronous pulley 13 is driven to rotate through the second synchronous toothed belt 12, thereby driving the second placement tray 6 and the single plastic forks thereon to rotate. As the second placement tray 6 continues to rotate, the single plastic forks 71 thereon will fall one by one from the discharge hole 15 onto the conveyor belt 51 and be transported backward one by one by the conveyor belt 51 in sequence.

[0040] like Figure 4As shown, the transfer mechanism 4 is also equipped with a removal component, which is used to remove the waste of the disassembled integral plastic fork 7. The removal component includes a vacuum adsorption component connecting bracket 47 fixed to the end of the piston rod of the third cylinder 46 and a plurality of vacuum adsorption components 48 fixed to the vacuum adsorption component connecting bracket 47. A recovery hopper is provided on the transfer platform 1 between the first placement tray 2 and the second placement tray 6 for recovering the plastic fork connecting ring 72. When all the single plastic forks have fallen, the first cylinder 37 is started again to push the transfer mechanism mounting bracket 39 down along the vertical movable guide rail 38 until the vacuum adsorption component 48 is close to the plastic fork connecting ring 72, and then the third cylinder 46 is started to push the vacuum adsorption component 48 down. , so that the vacuum adsorption component 48 is attached to the surface of the plastic fork connecting ring 72, and the plastic fork connecting ring 72 can be adsorbed and fixed by the vacuum adsorption component 48, and then the transfer mechanism mounting support 39 and the entire transfer mechanism 4 are pushed upward by the first cylinder 37, and at the same time, the first motor 33 is started in reverse to drive the first synchronous pulley 34 to rotate, thereby driving the first synchronous toothed belt 35 to rotate, and then driving the first cylinder mounting slide 36 and the transfer mechanism 4 thereon to move back, until the transfer mechanism 4 moves to the top of the recovery hopper and stops, releasing the adsorption of the plastic fork connecting ring 72, allowing it to fall into the recovery hopper for recovery.

[0041] like Figure 1 and Figure 12 As shown, the conveying portion includes a conveying platform 1 , at the end of which a conveyor 5 is installed. The conveyor 5 includes a conveyor belt 51 driven by a motor.

[0042] like Figure 12As shown, a pair of symmetrically distributed L-shaped plates 52 are provided above the conveyor 5. The L-shaped plates 52 are fixed to the outer frame of the conveyor 5 by bolts. The gap between the pair of L-shaped plates 52 forms a feed chute 53. The L-shaped plates 52 are located directly above the conveyor belt 51 and cover the entire conveyor belt 51 except for the starting portion, because the starting portion of the conveyor belt 51 is located below the discharge tray 14. The starting portion is not covered by the L-shaped plates 52, but there are two guide bars 54 fixed to the L-shaped plates 52 above it. The two guide bars 54 are also symmetrically distributed, and a guide groove 55 is formed between them. The distance between the L-shaped plates 52 and the guide bars 54 and the conveyor belt 51 is less than the thickness of a single plastic fork 71. The guide groove 55 is a V-shaped structure. The large end of the V-shaped structure of the guide groove 55 is located directly below the discharge hole 15, and the small end is the same width as the feed chute 53 and is exactly connected to the feed chute 53. When the single plastic fork 71 falls, it will first fall into the guide groove 53. 5, under the limiting action of the guide groove 55, the single plastic fork 71 will be automatically adjusted to be arranged in the longitudinal direction. Under the transportation of the conveyor belt 51, the single plastic fork 71 will be guided and arranged in the longitudinal direction and transported from the feed chute 53 to the next process, achieving the effect of automatic sorting and transmission, and then sent to the subsequent packaging machine for packaging. During the whole process, the transmission and packaging of multiple plastic forks can be completed at a time, which greatly improves the processing efficiency. In addition, each single plastic fork 71 can be automatically sorted and transmitted without manual sorting, which further improves the processing efficiency.

[0043] Example 2: In actual use, due to distance limitations, the transfer mechanism 4 needs to transfer the entire plastic fork 7 from the first placement tray 2 to the second placement tray 6. During the vacuum adsorption process and the lowering process, the entire plastic fork 7 may be slightly offset due to equipment vibration and other reasons. If this happens, the position of each single plastic fork 71 and the placement hole 62 will not completely correspond after the offset, which will result in failure to smoothly unload the material from the unloading hole 15, resulting in a freeze and the need for manual intervention. Although this situation does not occur frequently, once it occurs, it will also delay production efficiency. Therefore, this embodiment improves some structures of the transfer mechanism 4, such as Figure 13 、 Figure 14 As shown, the pressure plate connecting bracket 43 and the extrusion stop ring 44 are connected by at least two guide posts 49. The top ends of the guide posts 49 are fixed to the pressure plate connecting bracket 43, while the bottom ends are movably disposed within the sliding grooves 441 on the extrusion stop ring 44. The sliding grooves 441 are evenly spaced around the circumference of the extrusion stop ring 44 and correspond to the positions of the guide posts 49. In this embodiment, the bottom of the sliding grooves 441 is inclined downward in a clockwise direction (in other preferred embodiments, it can also be counterclockwise). Similarly, the bottom of the guide posts 49 also has an inclined surface that matches the bottom of the sliding grooves 441. Secondly, a return spring 40 is mounted on the outside of the guide posts 49 to ensure reset.

[0044] Slide groove 441 is formed within extrusion stop ring 44, and its top portion communicates with the top of extrusion stop ring 44 via an anti-slip opening 442. Anti-slip opening 442 is slightly smaller than slide groove 441, but has the same shape. Guide post 49 has an annular groove 491, the inner diameter of which matches the width of anti-slip opening 442, while the outer diameter of which matches the width of slide groove 441. This prevents the bottom end of guide post 49 from slipping out of slide groove 441.

[0045] With the above improvements, when the extrusion limit ring 44 is driven downward by the pressure plate connecting bracket 43 to compress the integral plastic fork, the pressure of the pressure plate connecting bracket 43 and the extrusion limit ring 44 causes the inclined surface at the bottom of the guide column 49 to slide downward along the inclined surface of the bottom of the sliding groove 441. Since the pressure plate connecting bracket 43 cannot rotate, the extrusion limit ring 44 rotates a small distance under the component force. At this time, if the integral plastic fork 7 it compresses is offset, it will be rotated a small distance along with it. Because there is downward pressure during rotation, the integral plastic fork 7 is rotated to align with the placement hole 62 and is pressed into the placement hole 62 and no longer rotates. If the integral plastic fork 7 is originally in the placement hole 62 during the process of pressing the extrusion limit ring 44 downward, its edge will be restricted by the edge of the placement hole 62 and cannot rotate. In this way, a tentative adjustment is performed during each downward pressing process to ensure that the position of the integral plastic fork is aligned with the placement hole 62.

[0046] Another aspect of the present invention provides a packaging machine equipped with a plastic fork sorting, arranging and conveying mechanism, and the packaging machine is also used to package a single plastic fork conveyed by a conveying part.
