Description

Technical Field

[0001] The present invention relates to the technical field of product packaging, and more specifically, to an intelligent automated packaging manipulator applied to production line transportation packaging. Background Art

[0002] Nowadays, in order to provide convenience, disposable tableware packaging has become a trend. Disposable tableware is usually packaged with a plastic film sealed bag for disposable tableware such as trays, forks and knives, and remains in a sealed packaging state before people open and use the plastic tableware.

[0003] Most traditional product packaging has achieved automation, and proprietary packaging machines are used to package products. Among them, in order to improve the overall packaging efficiency of products, manipulators are often used in combination to complete the packaging of products. For example, the patent number CN118062329B discloses "A manipulator of a packaging machine", which sets up a manipulator mechanism and uses multiple clamping vertical rods to move inward synchronously to clamp the items to be packaged.

[0004] However, when using rod-shaped clamping contact, since the contact surface with the product is small, in order to clamp the product upward, a greater clamping force is required. Especially for products such as plastic trays or paper trays with low hardness, if hard clamping is used, it is easy to cause product damage; at the same time, during the stacking process of products, when the next group of items to be packaged is intermittently transported and moved under the two clamping mechanisms, the two clamping mechanisms on both sides move down again at the same time, stacking the previous group of items to be packaged on the upper surface of this group of items to be packaged. At the moment of stacking, release the previous group of items to be packaged, and the clamping mechanism can continue to move down to clamp this group of items to be packaged, so as to achieve the clamping and stacking of multiple items to be packaged. This process uses three groups of clamping vertical rods to perform clamping, lifting, and lowering cyclic operations on the successively stacked products multiple times. On the one hand, the clamping steps are cumbersome. On the other hand, for products arranged in a vertical stack, only using rod-shaped clamping contact is difficult to better clamp and fix all the products upward; in addition, the products need to be conveyed out for packaging operations after stacking.

[0005] Therefore, in view of the above problems, an intelligent automated packaging manipulator applied to production line transportation packaging is proposed. Summary of the Invention

[0006] The purpose of the present invention is to solve existing practical problems and provide an intelligent automated packaging manipulator applied to production line transportation packaging compared with the prior art.

[0007] The purpose of the present invention can be achieved by the following technical solutions:

[0008] An intelligent automated packaging manipulator applied to production line transportation packaging, comprising a pair of conveyor belts arranged left and right and used for conveying tray products towards each other. On one side of each pair of conveyor belts, there is a positioning frame with a stacking space reserved between them. An stacking manipulator for adsorbing and flipping the tray products conveyed at intervals left and right is installed on the pair of positioning frames. A film feeding mechanism extending to its front and rear is arranged in the stacking space, and a hot film packaging manipulator is installed on the front side of the film feeding mechanism;

[0009] The stacking manipulator includes rotating shafts respectively rotatably installed on a pair of positioning frames. On each of the pair of rotating shafts, there is a support piece for adsorbing and positioning the bottom side of the tray product. A driving component for synchronously driving the pair of rotating shafts to turn is also fixedly installed between the pair of positioning frames;

[0010] The film feeding mechanism includes a first bracket, a second bracket, and a third bracket arranged in sequence from front to back. A lower plastic sealing film is installed for transmission between the first bracket and the second bracket. An upper plastic sealing film located above the lower plastic sealing film and outside the stacking space is installed for transmission between the first bracket and the third bracket. The hot film packaging manipulator includes a support seat. A turntable extending above the upper plastic sealing film is rotatably installed at the upper end of the support seat. An upper hot ironing die is installed at the end of the turntable through an upper push rod. A lower hot ironing die adapted to the upper hot ironing die and located below the lower plastic sealing film is fixedly installed at the bottom of the support seat. An annular cutting knife capable of being pushed up and down is also arranged outside the lower hot ironing die.

[0011] Further, the pair of support pieces are horizontally arranged in the same way. On the end walls of the pair of support pieces away from the rotating shafts, there are fitting adsorption grooves adapted to the bottom structure of the tray product, and the pair of fitting adsorption grooves are arranged in opposite directions up and down.

[0012] Further, an air cavity communicated with the rotating shaft is opened inside each of the pair of support pieces. A plurality of adsorption holes communicated with the air cavity are opened on the inner end walls of the pair of fitting adsorption grooves. A suction pump one is fixed at the end of each of the pair of conveyor belts, and the air pipe of the suction pump one is communicated with the end of the rotating shaft.

[0013] Further, the driving component includes gears respectively fixedly sleeved on the ends of the pair of rotating shafts. A moving frame is slidably installed between the inner walls of the pair of positioning frames. A rack meshing and driving with the pair of gears is fixed at the lower end of the moving frame, and a driving push cylinder for horizontally driving the moving frame is fixed at the outer end of one of the positioning frames. A guide plate slidably installed with the inner end wall of the moving frame is fixed between the pair of positioning frames. A guide rod fixedly connected with the left and right ends of the moving frame is movably sleeved inside the guide plate, and a guide block movably connected with the guide plate is also fixed at the outer end of the moving frame.

[0014] Further, a transfer plate is fixed between the first bracket and the second bracket and is arranged to fit the lower end face of the lower plastic film. A hot stamping notch is formed on the transfer plate at a position corresponding to the annular cutter and with an inner diameter larger than the outer diameter of the annular cutter.

[0015] Further, the lower end part of the upper hot stamping die is provided with a concave surface. A plurality of adsorption ports are formed in the top of the concave surface along the circumferential direction. A second suction pump communicated with the plurality of adsorption ports is fixedly installed at the upper end of the turntable.

[0016] Further, a fixed table corresponding to the turntable is fixed on one side of the lower end of the support base. The bottom end of the lower hot stamping die is connected to the upper end of the fixed table through a fixed shaft. The lower hot stamping die is located inside the hot stamping notch and a film stamping gap is reserved between the lower hot stamping die and the lower end face of the lower plastic film.

[0017] Further, the annular cutter is in a circular ring structure. A cross-shaped plate movably sleeved on the fixed shaft is fixed at the bottom end of the annular cutter. A lower push rod with a telescopic end fixedly connected to the cross-shaped plate is fixedly installed at the bottom end of the fixed table.

[0018] Compared with the prior art, the advantages of the present invention are as follows:

[0019] In this solution, a stacking manipulator arranged between a pair of conveyor belts is used to adsorb and flip the tray products conveyed at intervals left and right. Specifically, a driving component is used to drive a pair of supporting pieces to synchronously flip left and right intermittently, so as to alternately adsorb, flip and drop the tray products at the conveying ends of the two conveyor belts, realizing the lossless successive stacking of multiple tray products on the lower plastic film of the film feeding mechanism. Then, the lower plastic film conveys the stacked tray products to the film stamping and packaging manipulator. At this time, the tray products are located between the lower plastic film and the upper plastic film. The hot stamping edge method of pressing down the upper hot stamping die and closing the die with the lower hot stamping die is used to complete the sealing and packaging action of the stacked tray products. In this process, the upper movement of the annular cutter is used to punch and cut the seal, completing the conveying and packaging of the tray products.

[0020] By adding a transfer plate with a hot stamping notch below the lower plastic film, the transfer plate plays a role in guiding and limiting the lower plastic film. During the film stamping and packaging process, taking the lower hot stamping die adjacent to the lower end face of the lower plastic film as the fixed film stamping edge and the downward pressing of the upper hot stamping die as the moving film stamping edge, it is realized that only by relying on the downward movement of the upper hot stamping die, the fixed film stamping and edge cutting action can be quickly completed. At the same time, the opening of the hot stamping notch also facilitates the upward punching and cutting action of the annular cutter to obtain a more complete punching opening. After the punching and cutting action is completed, by using the negative pressure action and the turning action of the upper hot stamping die, the obtained independent package can be unloaded.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1: For disk-shaped products with low hardness and requiring stacked packaging, the rod-shaped side contact clamping method is adopted. On the one hand, it is difficult to perform non-destructive clamping and conveying. On the other hand, during the stacking process, multiple clamping, lifting, and lowering cyclic operations are required, resulting in cumbersome clamping steps and being unfavorable for the stable positioning of the stacked products. To address such problems, the following technical solutions are proposed:

[0035] The present invention discloses an intelligent automated packaging manipulator applied to production line transportation and packaging. Please refer to Figure 1 , which includes a pair of conveyor belts 1 arranged left and right and used for conveying pallet products 4 towards each other. On one side of each of the pair of conveyor belts 1, there is a positioning frame 2 with a stacking space reserved between them for placing the pallet products 4. A stacking manipulator 3 for adsorbing and flipping the pallet products 4 conveyed at intervals left and right is installed on the pair of positioning frames 2. A film feeding mechanism extending to its front and rear is provided in the stacking space, and a hot film packaging manipulator is installed on the front side of the film feeding mechanism.

[0036] Among them, please refer to Figures 2 - 4 , the stacking manipulator 3 includes rotating shafts 31 respectively rotatably installed on the pair of positioning frames 2. On each of the pair of rotating shafts 31, there is a support piece 32 for adsorbing and positioning the bottom side of the pallet product 4. The pair of support pieces 32 are horizontally arranged in the same way. On the end walls of the pair of support pieces 32 away from the rotating shafts 31, there are fitting adsorption grooves adapted to the bottom structure of the pallet product 4. The pair of fitting adsorption grooves are arranged in opposite directions up and down. In each of the pair of support pieces 32, there is an air cavity communicated with the rotating shaft 31. On the inner end walls of the pair of fitting adsorption grooves, there are multiple adsorption holes 321 communicated with the air cavity. At the ends of each of the pair of conveyor belts 1, there is a suction pump 33 fixed. The air pipe of the suction pump 33 is communicated with the end of the rotating shaft 31;

[0037] A driving component for synchronously driving the rotation of the pair of rotating shafts 31 is also fixedly installed between the pair of positioning frames 2. The driving component includes gears 34 respectively fixedly sleeved on the ends of the pair of rotating shafts 31. A moving frame 37 is slidably installed between the inner walls of the pair of positioning frames 2. A rack 35 meshing with the pair of gears 34 is fixed to the lower end of the moving frame 37. And a driving push cylinder 36 for horizontally driving the moving frame 37 is fixed to the outer end of one of the positioning frames 2. A guide plate slidably installed with the inner end wall of the moving frame 37 is fixed between the pair of positioning frames 2. A guide rod movably sleeved in the guide plate and fixedly connected to the left and right ends of the moving frame 37 is provided. And a guide block movably connected to the guide plate is also fixed to the outer end of the moving frame 37. The guide plate, guide rod, and guide block are added to improve the stability of the moving frame 37 driving the rack 35 to move horizontally, thereby improving the stability of the synchronous rotation of the pair of support pieces 32.

[0038] A pair of support sheets 32 are arranged in the same direction, and the bonding adsorption grooves of the two are arranged in opposite directions up and down, so that when one support sheet 32 ​​turns to one end of the conveyor belt 1, its bonding adsorption groove faces upward and is parallel to the conveying surface of the end of the conveyor belt 1, so as to receive the pallet product 4 transmitted. The pallet product 4 is conveyed to its bonding adsorption groove, and the suction pump 1 33 is started to realize the flexible adsorption positioning between the pallet product 4 and the support sheet 32. The suction pump 1 33 adopts a micro air pump, and the other support sheet 32 ​​is initially bonded with the bonding adsorption groove upward to completely adsorb the pallet product 4. After that, it is flipped to the other side. At this time, the adsorption groove faces downward, so when the corresponding suction pump 33 is closed, the adsorbed pallet product 4 can be placed on the film feeding mechanism. In this way, the driving component drives a pair of supporting plates 32 to turn over synchronously to the left and right intermittently, so as to alternately adsorb, flip and drop the pallet products 4 at the ends of the two conveyor belts 1. Compared with the traditional mechanical clamping method, it can realize the rapid and sequential stacking of multiple pallet products 4 on the film feeding mechanism, and the whole feeding process will not cause mechanical clamping damage to the pallet products 4;

[0039] The synchronously flipped support sheet 32 ​​is used for alternate product suction and lowering. The support sheet 32 ​​can be used as a positioning structure for the conveying end of the tray product 4. After the tray product 4 is conveyed to the end of the conveyor belt 1, it automatically fits in the fitting adsorption groove of the support sheet 32. The tray product 4 can be directional sucked and lowered by flipping left and right. Compared with the conventional suction cup manipulator structure, a single driving mechanical action can be used to complete the alternating feeding of products on both sides, without involving conventional suction positioning actions and up and down, left and right movement actions after suction. The structure and operation are relatively simple.

[0040] Also, see Figure 1 In order to improve the accuracy of conveying the pallet product 4, guide plates 5 compatible with the support plate 32 can be added at the front and rear ends of the conveyor belt 1 near the stacking space. When the support plate 32 is flipped to the conveying end of the conveyor belt 1, the support plate 32 just contacts with a pair of ends of the guide plates 5. The support plate 32 is located at the bottom of the bonding adsorption groove and is provided with an arc surface avoiding the setting of the guide plate 5, so that the setting of the guide plate 5 does not affect the flipping action of the support plate 32.

[0041] Embodiment 2: Based on Embodiment 1, this embodiment describes the film feeding mechanism and the hot film packaging robot in detail as follows:

[0042] See also Figure 1 and Figure 5 , Figure 6, the film feeding mechanism includes a first bracket 6 and a second bracket 7 arranged front and back. There is a third bracket 8 located in front of the stacking space between the first bracket 6 and the second bracket 7. A lower plastic sealing film 10 is installed for transmission between the first bracket 6 and the second bracket 7. An upper plastic sealing film 11 is installed for transmission between the first bracket 6 and the third bracket 8 and is located above the lower plastic sealing film 10. A transmission plate 9 is fixed between the first bracket 6 and the second bracket 7 and is arranged to fit the lower end face of the lower plastic sealing film 10. A hot stamping notch 901 is formed on the transmission plate 9.

[0043] Please refer to Figure 7 , Figure 8 , the hot stamping and packaging manipulator includes a support base 12. A turntable 13 is rotatably installed at the upper end of the support base 12, and the inner end of the turntable 13 extends above the upper plastic sealing film 11. An upper hot stamping die 15 that moves up and down is installed at the end of the turntable 13 through an upper push rod 14. A lower hot stamping die 17 that is adapted to the upper hot stamping die 15 and is located below the lower plastic sealing film 10 is fixedly installed at the bottom of the support base 12. Hot stamping ring edges are provided on the outer edges of the upper and lower opposite end faces of the upper hot stamping die 15 and the lower hot stamping die 17. The hot stamping ring edges are composed of annular electric heating wires and are configured with an electric heating system. After the electric heating system is started, high-temperature heating of the hot stamping ring edges is achieved. An annular cutting knife 18 that can be pushed up and down is also provided outside the lower hot stamping die 17.

[0044] The lower end of the upper hot stamping die 15 is provided with an inner concave surface for accommodating the stacked tray products 4. The widths of the lower plastic sealing film 10 and the upper plastic sealing film 11 are greater than the outer diameter of the upper hot stamping die 15. A fixed table 16 corresponding to the turntable 13 is fixed on one side of the lower end of the support base 12. The bottom end of the lower hot stamping die 17 is connected to the upper end of the fixed table 16 through a fixed shaft. The lower hot stamping die 17 is located inside the hot stamping notch 901 and there is a hot stamping gap reserved with the lower end face of the lower plastic sealing film 10;

[0045] The annular cutting knife 18 has a circular ring structure. The outer diameter of the annular cutting knife 18 is greater than that of the lower hot stamping die 17. A cross-shaped plate that is movably sleeved on the fixed shaft is fixed at the bottom end of the annular cutting knife 18. A lower push rod 19 with a telescopic end fixedly connected to the cross-shaped plate is fixedly installed at the bottom end of the fixed table 16. The hot stamping notch 901 corresponds to the position of the annular cutting knife 18 and its inner diameter is greater than the outer diameter of the annular cutting knife 18.

[0046] A plurality of adsorption ports are formed along the circumferential direction at the top of the inner concave surface of the upper hot stamping die 15. A second suction pump 20 that is communicated with the plurality of adsorption ports is fixedly installed at the upper end of the turntable 13. Similarly, an inner concave surface that protrudes downward is also provided at the upper end of the lower hot stamping die 17, and the inner concave depth of this inner concave surface is less than the inner concave depth of the inner concave surface of the upper hot stamping die 15.

[0047] Please refer to Figure 1 and Figure 5, the film feeding mechanism is vertically arranged between a pair of conveyor belts 1 and extends in the front and rear directions. The lower plastic sealing film 10 and the upper plastic sealing film 11 are respectively arranged between the first bracket 6 and the second bracket 7, and between the first bracket 6 and the third bracket 8. The first bracket 6 is provided with winding rollers for winding the lower plastic sealing film 10 and the upper plastic sealing film 11. The second bracket 7 and the third bracket 8 are respectively provided with unwinding rollers for unwinding the lower plastic sealing film 10 and the upper plastic sealing film 11. One end of the unwinding roller of the lower plastic sealing film 10 extends to the rear side of the stacking space. A plastic sealing film structure with different conveying lengths up and down is set, which cooperates with the stacking manipulator 3 that alternately sucks and places materials left and right, facilitating the rapid stacking of the tray products 4 on the lower plastic sealing film 10 one by one. Then, the stacked tray products 4 are conveyed to the hot film packaging manipulator by the conveying action of the lower plastic sealing film 10, which is convenient for stacking the tray products and then horizontally conveying them between the two films. According to the stacked height to be packaged, the reserved packaging space between the lower plastic sealing film 10 and the upper plastic sealing film 11 is reasonably designed.

[0048] Please refer to Figure 9 , Figure 10 , during the hot film packaging process, the lower hot stamping die 17 is positioned inside the hot stamping groove 901 and does not contact the lower end face of the lower plastic sealing film 10. The upper push rod 14 is started, and the upper hot stamping die 15 is lowered by using the upper push rod 14. The upper hot stamping die 15 is pressed on the upper plastic sealing film 11 and gradually lowered until it is combined with the lower hot stamping die 17. The hot stamping ring edges on the opposite surfaces of the upper hot stamping die 15 and the lower hot stamping die 17 are in contact, and the contact surface between the lower plastic sealing film 10 and the upper plastic sealing film 11 is ironed and sealed, wrapping the tray product 4 between the upper and lower two films.

[0049] After the hot film packaging, the annular cutter 18 is lifted upward, and the annular blade at the top of the annular cutter 18 is used to punch and cut the seal to obtain a complete packaging bag. Since the widths of the lower plastic sealing film 10 and the upper plastic sealing film 11 are greater than the outer diameter of the upper hot stamping die 15, there are still remaining edges outside the film after packaging. Therefore, after the seal is punched and cut, the film does not break directly, and the film can be continuously wound by using the winding roller.

[0050] Finally, by using the negative pressure action and the turning action of the upper hot stamping die 15, the obtained sealed film packaging bag is quickly turned to the straight outer side for blanking, completing the entire conveying and packaging work of the tray product 4. Here, it should be added that since the conveying length of the lower plastic sealing film 10 is much greater than that of the upper plastic sealing film 11, after the film is punched and cut, for the packaging of the next group of tray products 4, the lower plastic sealing film 10 needs to be wound a certain length. Therefore, the lower plastic sealing film 10 between the two punching cuts has a certain degree, so that the unwinding action of the lower plastic sealing film 10 can be repeated to facilitate the full utilization of the unused part of the lower plastic sealing film 10.

[0051] In summary: This solution mainly targets the stacking transportation and packaging of disk-shaped products with relatively low hardness. A stacking manipulator 3 is arranged between a pair of conveyor belts 1 to adsorb and flip the pallet products 4 transported at intervals left and right.

[0052] Specifically: A driving component is used to drive a pair of supporting pieces 32 to synchronously flip left and right intermittently, so as to alternately adsorb, flip, and drop the pallet products 4 at the conveying ends of the two conveyor belts 1, realizing the lossless sequential stacking of multiple pallet products 4 on the lower plastic sealing film 10 of the film feeding mechanism. Then, the lower plastic sealing film 10 conveys the stacked pallet products 4 to the hot film packaging manipulator. At this time, the pallet products 4 are located between the lower plastic sealing film 10 and the upper plastic sealing film 11. The upper hot stamping die 15 is pressed down to cooperate with the lower hot stamping die 17 for edge hot stamping to quickly complete the sealing and packaging operation of the stacked pallet products 4. During this process, the upper movement of the annular cutter 18 is used to punch and cut the seal. Finally, by using the negative pressure action and turning action of the upper hot stamping die 15, the obtained independent package can be unloaded, completing the entire transportation and packaging of the pallet products 4.

[0053] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto; any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes; should be covered by the protection scope of the present invention.
