Description

Technical Field

[0001] The present invention relates to the technical field of product packaging, and more specifically, to an intelligent automated packaging robot 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 in plastic film bags, such as trays and knives and forks, and kept in a sealed packaging state before people open and use the plastic tableware.

[0003] Traditional product packaging is mostly automated, using proprietary packaging machines to package products. In order to improve the overall packaging efficiency of the product, it is often used in conjunction with a robot to complete the product packaging. For example, patent number CN118062329B discloses "A robot for a packaging machine", which is equipped with a robot mechanism and uses multiple clamping longitudinal rods to move synchronously inward to clamp the packaged items.

[0004] However, the rod-shaped clamping contact has a small contact surface with the product, so a greater clamping force is required to clamp the product upward, especially for plastic pallets or paper pallets with low hardness. If hard clamping is used, it is easy to cause product damage; at the same time, during the product stacking process, when the next group of items to be packaged is intermittently moved and transported to the bottom of the two clamping mechanisms, the clamping mechanisms on both sides move down again at the same time to stack the previous group of items to be packaged on the upper surface of the previous group of items to be packaged. At the moment of stacking, the previous group of items to be packaged is released, and the clamping mechanism can continue to move down to clamp the current group of items to be packaged, thereby achieving clamping and stacking of multiple items to be packaged. This process uses three groups of clamping longitudinal rods to clamp, move up, and lower the stacked products multiple times. On the one hand, the clamping steps are cumbersome, and on the other hand, for products stacked in the vertical direction, it is difficult to better clamp and fix all the products upward using only rod-shaped clamping contacts; in addition, after stacking, the products need to be conveyed out for packaging operations.

[0005] Therefore, in order to solve the above problems, an intelligent automated packaging robot is proposed for production line transportation packaging. Summary of the invention

[0008] Furthermore, the pair of supporting plates are also arranged horizontally, and a fitting adsorption groove adapted to the bottom structure of the tray product is opened on the end wall of the pair of supporting plates away from the rotating shaft, and the pair of fitting adsorption grooves are arranged in reverse up and down.

[0009] Furthermore, a pair of the supporting plates are each provided with a ventilation cavity connected to the rotating shaft, a pair of the bonding adsorption grooves are each provided with a plurality of adsorption holes connected to the ventilation cavity on the inner end wall, and a pair of the conveyor belt ends are each fixed with a suction pump, and the air pipe of the suction pump is connected to the end of the rotating shaft.

[0010] Furthermore, the driving assembly includes gears fixedly sleeved on the ends of a pair of rotating shafts, a moving frame is slidably installed between the inner walls of a pair of positioning frames, a rack meshing 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 to the left and right ends of the moving frame is movably sleeved in the guide plate, and a guide block movably engaged with the guide plate is also fixed at the outer end of the moving frame.

[0011] Furthermore, a conveying plate arranged to fit the lower end surface of the lower plastic film is fixed between the first and second brackets, and a hot stamping notch corresponding to the position of the annular cutter and having an inner diameter larger than the outer diameter of the annular cutter is provided on the conveying plate.

[0012] Furthermore, the lower end of the upper hot stamping die is provided with an inner concave surface, the top of the inner concave surface is provided with a plurality of suction ports in a circular direction, and a second suction pump connected to the plurality of suction ports is fixedly mounted on the upper end of the turntable.

[0013] Furthermore, a fixed table corresponding to the turntable is fixed to one side of the lower end of the support seat, and the bottom end of the lower hot stamping mold is connected to the upper end of the fixed table through a fixed shaft. The lower hot stamping mold is located inside the hot stamping groove and a hot stamping film gap is reserved with the lower end surface of the lower plastic sealing film.

[0015] Compared with the prior art, the advantages of the present invention are: This solution uses a stacking robot located between a pair of conveyor belts to adsorb and flip the pallet products conveyed at intervals to the left and right. Specifically, a driving component is used to drive a pair of support plates to synchronously flip left and right intermittently, so as to alternately adsorb, flip and drop the pallet products at the conveying ends of the two conveyor belts, so as to achieve non-destructive stacking of multiple pallet products on the lower plastic sealing film of the film feeding mechanism, and then the lower plastic sealing film conveys the stacked pallet products to the hot stamping packaging robot. At this time, the pallet products are located between the lower plastic sealing film and the upper plastic sealing film, and the sealing edge of the stacked pallet products is completed by the downward pressure of the upper hot stamping mold and the closing of the lower hot stamping mold. In this process, the upward action of the circular cutter is used to punch the seal to complete the conveying and packaging of the pallet products.

[0016] By adding a conveyor plate with a hot stamping notch under the lower plastic sealing film, the conveyor plate plays a guiding and limiting role for the lower plastic sealing film. During the hot stamping packaging process, the lower hot stamping die is arranged near the lower end surface of the lower plastic sealing film as a fixed hot stamping edge, and the upper hot stamping die is pressed downward as a dynamic hot stamping edge, so that the fixed film hot stamping edge action can be quickly completed by relying only on the downward action of the upper hot stamping die. At the same time, the opening of the hot stamping notch also facilitates the upward punching action of the annular cutter to obtain a more complete punching cut. After the punching action is completed, the negative pressure action and the turning action of the upper hot stamping die can be used to unload the obtained independent package.

[0019] The following will combine the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0020] Embodiment 1: For disc products with low hardness and requiring stacking packaging, a rod-shaped side contact clamping method is adopted. On the one hand, it is difficult to perform lossless clamping and conveying. On the other hand, multiple clamping, moving up, and lowering cycle operations are required during the stacking process, resulting in cumbersome clamping steps and not conducive to stable positioning of stacked products. To address this problem, the following technical solutions are proposed: The present invention discloses an intelligent automatic packaging robot for production line transportation packaging, please refer to Figure 1, including a pair of conveyor belts 1 arranged on the left and right and used for conveying pallet products 4 towards each other, a positioning frame 2 is provided on the opposite side of the pair of conveyor belts 1, and a stacking space for placing the pallet products 4 is reserved therebetween, a stacking robot 3 for adsorbing and flipping the pallet products 4 conveyed at intervals on the left and right is installed on the pair of positioning frames 2, a film feeding mechanism extending to the front and rear of the stacking space is provided in the stacking space, and a hot film packaging robot is installed on the front side of the film feeding mechanism.

[0021] Among them, see Figure 2-Figure 4 The stacking manipulator 3 includes a rotating shaft 31 which is rotatably mounted on a pair of positioning frames 2, and a pair of rotating shafts 31 are fixed with a support sheet 32 ​​for adsorbing and positioning the bottom side of the tray product 4. The pair of support sheets 32 are horizontally arranged in the same manner, and a pair of support sheets 32 are provided with a fitting adsorption groove adapted to the bottom structure of the tray product 4 on the end wall away from the rotating shaft 31. The pair of fitting adsorption grooves are arranged in reverse up and down, and a ventilation cavity connected to the rotating shaft 31 is provided inside the pair of support sheets 32. A plurality of adsorption holes 321 connected to the ventilation cavity are provided on the inner end wall of the pair of fitting adsorption grooves, and a suction pump 33 is fixed at the end of the pair of conveyor belts 1, and the air pipe of the suction pump 33 is connected to the end of the rotating shaft 31; A driving assembly for synchronously steering a pair of rotating shafts 31 is also fixedly installed between a pair of positioning frames 2, and the driving assembly includes gears 34 fixedly sleeved on the ends of a pair of rotating shafts 31, a moving frame 37 is slidably installed between the inner walls of a pair of positioning frames 2, a rack 35 meshing with a pair of gears 34 is fixed at the lower end of the moving frame 37, and a driving push cylinder 36 for horizontally driving the moving frame 37 is fixed at 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 fixedly connected to the left and right ends of the moving frame 37 is movably sleeved in the guide plate, and a guide block movably engaged with the guide plate is also fixed at the outer end of the moving frame 37, and the guide plate, guide rod and guide block are additionally provided to improve the stability of the moving frame 37 driving the rack 35 to transport in the horizontal direction, thereby improving the stability of the synchronous steering of the pair of supporting plates 32.

[0022] 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; 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. 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.

[0023] Embodiment 2: Based on Embodiment 1, this embodiment describes the film feeding mechanism and the hot film packaging robot in detail as follows: See also Figure 1 and Figure 5 , Figure 6The film feeding mechanism includes a bracket 1 6 and a bracket 2 7 arranged in front and back, a bracket 3 8 located in front of the stacking space is arranged between the bracket 1 6 and the bracket 2 7, a lower plastic sealing film 10 is installed and transported between the bracket 1 6 and the bracket 2 7, an upper plastic sealing film 11 located above the lower plastic sealing film 10 is installed and transported between the bracket 1 6 and the bracket 3 8, a conveying plate 9 arranged to fit the lower end surface of the lower plastic sealing film 10 is fixed between the bracket 1 6 and the bracket 2 7, and a hot stamping slot 901 is opened on the conveying plate 9.

[0024] See also Figure 7 , Figure 8 The hot stamping packaging robot includes a support seat 12, a turntable 13 with an inner end extending to the top of the upper plastic sealing film 11 is rotatably installed on the upper end of the support seat 12, an upper hot stamping die 15 that moves up and down is installed on the end of the turntable 13 through an upper push rod 14, and a lower hot stamping die 17 that is compatible with 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 seat 12. The outer edges of the upper and lower opposite end surfaces of the upper and lower hot stamping die 15 and the lower hot stamping die 17 are both provided with hot stamping film ring edges, which are composed of annular electric heating wires and are equipped with an electric heating system. After the electric heating system is started, high-temperature heating of the hot stamping film ring edges is achieved. The outer side of the lower hot stamping die 17 is also provided with a ring-shaped cutter 18 that can be pushed up and down.

[0025] 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 film 10 and the upper plastic film 11 are larger than the outer diameter of the upper hot stamping die 15. A fixed table 16 corresponding to the turntable 13 is fixed to one side of the lower end of the support seat 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 a hot stamping film gap is reserved with the lower end surface of the lower plastic film 10. The annular cutter 18 has a circular ring structure, and its outer diameter is larger than the lower hot stamping die 17. A cross-shaped plate movably connected to the fixed shaft is fixed at the bottom end of the annular cutter 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 platform 16. The hot stamping notch 901 corresponds to the position of the annular cutter 18 and its inner diameter is larger than the outer diameter of the annular cutter 18.

[0026] A plurality of suction ports are provided at the top of the inner concave surface of the upper hot stamping die 15 in a circular direction, and a suction pump 20 connected to the plurality of suction ports is fixedly installed at the upper end of the turntable 13. Similarly, a downwardly protruding inner concave surface is also provided at the upper end of the lower hot stamping die 17, and the inner concave depth of the inner concave surface is smaller than the inner concave depth of the inner concave surface of the upper hot stamping die 15.

[0027] See also Figure 1 as well as Figure 5The film feeding mechanism is vertically arranged between a pair of conveyor belts 1 and extends in the front-to-back direction. The lower plastic sealing film 10 and the upper plastic sealing film 11 are arranged between the bracket 1 6 and the bracket 2 7 and the bracket 1 6 and the bracket 3 8 respectively. The bracket 1 6 is provided with a winding roller for winding the lower plastic sealing film 10 and the upper plastic sealing film 11. The bracket 2 7 and the bracket 3 8 are respectively provided with unwinding rollers for unwinding the lower plastic sealing film 10 and the upper plastic sealing film 11, and one end of the unwinding roller of the lower plastic sealing film 10 extends to the stacking space. On the rear side of the room, a plastic film structure with different upper and lower conveying lengths is set, and the stacking robot 3 that alternately sucks and lowers the material left and right is used to facilitate the rapid stacking of the pallet products 4 on the lower plastic film 10 one by one, and then the conveying action of the lower plastic film 10 conveys the stacked pallet products 4 to the hot stamping packaging robot, so that the pallet products can be stacked and then horizontally conveyed between the two films. According to the stacking height to be packaged, the reserved packaging space between the lower plastic film 10 and the upper plastic film 11 is reasonably designed.

[0028] See also Fig. 9 , Fig.10 During the hot stamping packaging process, the lower hot stamping die 17 is positioned at the inner side of the hot stamping notch 901 and does not contact the lower end surface of the lower plastic sealing film 10. The upper push rod 14 is started, and the upper hot stamping die 15 is lowered by 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 in contact with the lower hot stamping die 17. The hot stamping film 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, and the tray product 4 is wrapped between the upper and lower films.

[0029] After the hot stamping film is sealed, the annular cutter 18 is lifted upward, and the annular blade at the top of the annular cutter 18 is used to punch the seal to obtain a complete packaging bag. Since the width of the lower plastic sealing film 10 and the upper plastic sealing film 11 is larger than the outer diameter of the upper hot stamping die 15, there is still a margin outside the film after plastic sealing, so that the film is not directly broken after the seal is punched, and the film can be continuously rolled up using a winding roller.

[0030] Finally, by utilizing the negative pressure and turning action of the upper hot stamping mold 15, the obtained sealed film packaging bag is quickly turned to the straight outside for unloading, completing the entire conveying and packaging work of the pallet product 4. It should be added here that since the conveying length of the lower plastic sealing film 10 is much longer than the conveying length of the upper plastic sealing film 11, after the sealing film is punched and cut, the next group of pallet products 4 are packaged, and the lower plastic sealing film 10 needs to be rolled up to a certain length. Therefore, the lower plastic sealing film 10 between the two punching openings has a certain degree, so that the lower plastic sealing film 10 can be repeatedly unwound to facilitate the full utilization of the unused portion of the lower plastic sealing film 10.

[0031] In summary: This solution is mainly aimed at the stacked conveying and packaging of disk-shaped products with relatively small hardness. The stacking manipulator 3 arranged between a pair of conveyor belts 1 adsorbs and flips the pallet products 4 conveyed at intervals left and right. Specifically: The 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 successive 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 hot edge method of pressing down the upper hot stamping die 15 and closing the die with the lower hot stamping die 17 is used to quickly complete the sealing and packaging action 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 the turning action of the upper hot stamping die 15, the obtained independent packages can be discharged, completing the entire conveying and packaging of the pallet products 4.

[0032] 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, and should be covered by the protection scope of the present invention.
