DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figures 1 to 9 In an embodiment of the present invention, a high-efficiency automatic bagging device includes: The combined conveyor belt 10 is composed of a plurality of material conveyor belts 11 arranged side by side, the ends of each material conveyor belt 11 are arranged at a certain distance along the conveying direction thereof, and a blocking bar 12 is provided at the end of each material conveyor belt 11 for stopping the material at the end of each material conveyor belt 11; The bag supply device 20 is provided with a bag supply box body 21 and a plurality of groups of bag supply suction cups 22. The bag supply suction cups 22 suck a plurality of plastic inner bags from the bag supply box body 21 and move to the bag support station; The bag-opening device 40 is provided with a plurality of groups of support rod assemblies 41, which are installed at the bag-opening station to open the plastic inner bag and keep the plastic inner bag in the open state; The clamping device 60 is provided with a plurality of clamping arms, which can simultaneously clamp the materials parked on the plurality of material conveyor belts 11, and insert the materials into the plastic inner bags opened by the corresponding support rod assemblies 41, thereby completing the bagging operation of the materials; The unloading conveyor belt 13 is used to receive the materials after the bagging by the clamping device 60 and unload them; and The main beam 14 is provided with a main slide rail 15 and a main driving member. The bag supply device 20 and the material clamping device 60 are respectively slidably connected to the main slide rail 15 and form a transmission connection with the main driving member.

[0027] Specifically, in order to improve the operating efficiency of the bagging equipment, it is preferred to set up three material conveyor belts 11 so that three materials after pad printing can be transported into the bagging equipment at the same time. It can be understood that a corresponding photoelectric sensor can be set at the starting end of the combined conveyor belt 10 to sense the situation of the material being conveyed in. After the material is conveyed to the end of the material conveyor belt 11 and is blocked by the blocking bar 12, it is preferred to automatically control the conveyor belt to stop running and wait for the clamping device 60 to clamp the material.

[0028] When materials are parked at the ends of the three material conveyor belts 11, the material clamping drive assembly 17 operates to drive the material clamping support arm to move to the rear side of the material, and then the material clamping vertical movement cylinder 65 drives the material clamping main plate 66 to move downward, so that the material clamping support arm clamps the material. Then the first cylinder 68 and the second cylinder 610 operate respectively to drive the first material clamping support arm 61 and the second material clamping support arm 62 to move, so that the three material clamping support arms are arranged in a row along the direction of the bag-opening device 40, so as to facilitate the synchronous insertion of the three materials into the three opened plastic inner bags.

[0029] The bag supply box 21 is filled with stacked plastic inner bags. The bag supply suction cup 22 can be moved to the top of the starting end of the empty box output conveyor 31 under the drive of the bag supply driving assembly 16, where a bag supply box 21 filled with plastic inner bags is fixed. The bag supply suction cup 22 is then driven downward by the bag supply vertical movement module 24 to allow the bag supply suction cup 22 to absorb the plastic inner bags inside the bag supply box 21 and move to the front end of the bag holding device 40, waiting for the bag holding device 40 to be inserted into the plastic inner bag.

[0030] like Figure 7 As shown, since the initial state of the plastic inner bag is flat, in order to form an opening, the bag support strip 44 is inserted, and preferably, a bag opening suction nozzle 47 is provided on the side of the unloading conveyor belt 13 close to the bag support device 40. The bag supply suction cup 22 moves the absorbed plastic inner bag downward, so that its lower side approaches the unloading conveyor belt 13 and is sucked by the bag opening suction nozzle 47, and then the bag supply suction cup 22 moves upward for a certain distance, so that the plastic inner bag forms a certain opening.

[0031] Subsequently, the strut assembly 41 is driven by the bag insertion cylinder 45 to move along the bag insertion slide rail 46 toward the open plastic inner bag, so that the bag support strips 44 on the first vertical plate 42 and the second vertical plate 43 are respectively inserted into the inner plastic bag. Then, the strut motor 52 is used to drive the strut synchronous belt 53 to rotate a certain angle, so that the first vertical plate 42 and the second vertical plate 43 are separated by a certain distance, so as to open the plastic inner bag and keep the plastic inner bag in the open state. The material clamping device 60 can be driven by the material clamping drive assembly 17 to move toward the open plastic inner bag, and then insert the material into the plastic inner bag, and then continue to move a certain distance toward the unloading conveyor belt 13, and place the material in the plastic inner bag on the unloading conveyor belt 13 to perform the unloading operation. Finally, each device, mechanism or component returns to its original position, ready for the next bagging operation.

[0032] Secondly, the main driving part is provided with a bag supply driving assembly 16 and a material clamping driving assembly 17. The bag supply driving assembly 16 is connected to the bag supply device 20 by transmission, and drives the bag supply device 20 to move forward and backward along the main slide rail 15, thereby completing the corresponding moving operation; the material clamping driving assembly 17 is connected to the material clamping device 60 by transmission, and drives the material clamping device 60 to move forward and backward along the main slide rail 15, thereby completing the corresponding moving operation. Each group of strut assemblies 41 is set corresponding to the material position at the end of each material conveyor belt 11, and performs a stretching operation on the plastic inner bag, while stably keeping the plastic inner bag in an open state that can be bagged.

[0033] Thirdly, it can significantly improve production efficiency, reduce manual intervention through automated operation, and greatly increase production speed. It can also reduce production costs, reduce manpower requirements, reduce labor intensity, and improve material utilization. It can also ensure printing quality, high-precision positioning and stable pad printing process to ensure the consistency and stability of printing quality. At the same time, it can improve the level of intelligence, use intelligent control systems to achieve real-time monitoring and analysis of production data, and optimize production processes. After printing, the system automatically moves the product to the unloading area, and uses the machine vision system to perform quality inspection on the product, identify and remove unqualified products, and ensure the quality of the final product. Integrate PLC, touch screen and industrial-grade computing system to realize the functions of automated control, data recording and analysis, fault alarm and remote diagnosis of the entire production line, and improve the level of intelligence of production management.

[0034] like Figure 4 and Figure 5 As shown, preferably, the material clamping device 60 is also provided with a material clamping cross beam 64, a material clamping vertical movement cylinder 65 and a material clamping main plate 66, the two ends of the material clamping cross beam 64 are respectively slidably connected to the main slide rail 15 of the main beam frame 14, the material clamping vertical movement cylinder 65 is installed on the material clamping cross beam 64, the material clamping main plate 66 is fixedly connected to the piston end of the material clamping vertical movement cylinder 65, and the multiple material clamping support arms are respectively installed on the material clamping main plate 66.

[0035] Specifically, in order to improve the stability of the clamping device 60, it is preferred to configure the main beam frame 14 as two brackets arranged in parallel, and to respectively configure two main slide rails 15 so that the clamping beam 64 can straddle the main beam frame 14 respectively.

[0036] like Figure 5As shown, preferably, the material clamping device 60 is also provided with a first material clamping arm 61, a second material clamping arm 62 and a third material clamping arm 63, and the shape of the material clamping main plate 66 is set to be a Z-shaped plate, one end of which is provided with a first slide rail 67 and a first cylinder 68, and the other end of which is provided with a second slide rail 69 and a second cylinder 610; the first material clamping arm 61 is slidably connected to the first slide rail 67, and forms a transmission connection with the piston end of the first cylinder 68; the second material clamping arm 62 is slidably connected to the second slide rail 69, and forms a transmission connection with the piston end of the second cylinder 610; the third material clamping arm 63 is fixedly connected to the middle section of the material clamping main plate 66.

[0037] Specifically, the first material clamping arm 61, the third material clamping arm 63 and the second material clamping arm 62 are respectively arranged at a certain distance along the conveying direction of the material conveyor belt 11, and correspond to the ends of the three material conveyor belts 11 that are combined side by side and arranged at a certain distance, so that the corresponding material clamping arm can clamp the material parked at the corresponding position.

[0038] Secondly, since the plastic inner bags opened by the bag-opening device 40 are in the same parallel line, in order to insert the three materials into the three plastic inner bags at the same time, it is preferred to set a first cylinder and a second cylinder 610 at the first clamping arm 61 and the second clamping arm 62, so as to drive the first clamping arm 61 and the second clamping arm 62 so that they can move to the same parallel line as the third clamping arm 63.

[0039] like Figure 5 and Figure 8 As shown, preferably, the bag supply device 20 is also provided with a bag supply beam 23, a bag supply vertical movement module 24, a bag supply motor 25 and a bag supply main plate 26, the two ends of the bag supply beam 23 are respectively slidably connected to the main slide rail 15 of the main beam frame 14, the bag supply vertical movement module 24 and the bag supply motor 25 are respectively installed on the bag supply beam 23, and the bag supply vertical movement module 24 is transmission-connected to the bag supply motor 25, the bag supply main plate 26 is fixedly connected to one end of the bag supply vertical movement module 24, and a plurality of bag supply suction cups 22 are provided.

[0040] Specifically, similarly, the bag supply beam 23 also straddles the main slide rail 15 of the main beam frame 14. The bag supply motor 25 preferably adopts a stepper motor or a reduction motor, and the bag supply vertical movement module 24 can adopt a knk5008 linear module, so that under the drive of the bag supply motor 25, the bag supply vertical movement module 24 can drive the bag supply main plate 26 to perform linear motion in the vertical direction.

[0041] like Figure 8 and Fig. 9As shown, preferably, the bag supply device 20 is also provided with a box input conveyor belt 30, an empty box output conveyor belt 31, a box body transverse movement mechanism 34 and a box body stabilizing cylinder 32. The box body input conveyor belt 30 is used to transport the bag supply box body 21 filled with plastic inner bags to the box body transverse movement mechanism 34. The box body transverse movement mechanism 34 moves the bag supply box body 21 to the starting end of the empty box output conveyor belt 31. Two groups of box body stabilizing cylinders 32 are respectively installed on both sides of the empty box output conveyor belt 31, and fix the bag supply box body 21 at the starting end of the empty box output conveyor belt 31.

[0042] Specifically, the arrangement of the box body stabilizing cylinder 32 can facilitate the bag supply suction cup 22 to absorb the plastic inner bag inside the bag supply box body 21. The piston end of the box body stabilizing cylinder 32 is also provided with a right angle fork 33, and the right angle fork 33 can fork the corner of the bag supply box body 21 under the drive of the box body stabilizing cylinder 32, thereby forming a limiting effect on the bag supply box body 21, so that it can be stably parked at the starting end of the empty box output conveyor belt 31.

[0043] Secondly, when all the plastic inner bags inside the bag supply box 21 are grabbed and removed, the box stabilizing cylinder 32 can retract the right-angle fork 33, releasing the limiting effect on the bag supply box 21, so that the remaining empty boxes can be driven by the empty box output conveyor 31 to move a certain distance to the output end of the empty box output conveyor 31, thereby making room for the starting end of the empty box output conveyor 31, so that the box transverse movement mechanism 34 can move a bag supply box 21 filled with plastic inner bags to this position again for the plastic inner bag supply operation.

[0044] Again, a corresponding sensor (not shown in the figure) can be set at a suitable position corresponding to the starting end of the empty box output conveyor 31, so that it can sense whether all the plastic inner bags inside the bag supply box 21 are grabbed and removed, and then feedback the corresponding signal to the control device (not shown in the figure), so that it can control the corresponding device to operate, release the empty box, and move a fully loaded bag supply box 21 to the corresponding position.

[0046] Specifically, the side wall of the bag supply box 21 is firstly sucked by the box suction cup 39, and then the sucked bag supply box 21 is pushed outward by the box cylinder 37 for a certain distance to facilitate lateral movement. Then the box motor 36 is operated to drive the box lateral movement module 35 to operate, driving the box gripper 38 and the bag supply box 21 to move lateral, thereby moving the bag supply box 21 fully loaded with plastic inner bags to the starting end of the empty box output conveyor 31.

[0047] like Figure 7 As shown, preferably, the bag-stretching device 40 is also provided with a bag-inserting cylinder 45, a bag-inserting slide rail 46 and a support rod main plate 50, the support rod main plate 50 is slidably connected to the bag-inserting slide rail 46, and forms a transmission connection with the piston end of the bag-inserting cylinder 45, and a plurality of support rod assemblies 41 are respectively installed on the support rod main plate 50.

The main conveyor belt 70 then transports the material to the automatic bagging device for bagging, and then performs the unloading operation.

[0054] Specifically, the loading device is provided with a loading robot arm 78 and a loading suction cup 79, so as to suck the materials in the external box body and move them to the transfer device 71. The transfer device 71 is provided with a transfer jig 72 and a jig turntable 73. A plurality of transfer jigs 72 are evenly distributed on the jig turntable 73.

[0058] Specifically, the material transfer suction nozzle 83 and the material transfer finger 85 are arranged at a certain distance from each other, and correspond to the loading station 95 and the unloading station 97 on the pad printing equipment 90, that is, the material transfer suction nozzle 83 sucks a material to be pad printed from the transfer equipment 71, and then, driven by the material transfer robot arm 81, moves to the top of the pad printing jig 92 of the loading station 95, and then the material transfer robot arm 81 drives the material transfer bracket 82 to move downward, so that the material transfer suction nozzle 83 places the material to be pad printed on the pad printing jig 92 of the loading station 95; at the same time, the material transfer fingers 85 at the other end of the material transfer bracket 82 are also driven to move downward synchronously, and are located on both sides of the pad printing jig 92 of the unloading station 97, so that the finger cylinder 86 is operated, and the material transfer fingers 85 are driven to clamp the material that needs to be removed from the pad printing jig 92 of the unloading station 97. Then, the material transfer robot arm 81 drives the material transfer bracket 82 to move upward, and moves the clamped material pieces toward the main conveyor belt 70, so that the material transfer fingers 85 place the clamped material pieces on the main conveyor belt 70 for transportation.

[0059] Secondly, on both sides of the pad printing jig 92 of the loading station 95, there are also limit push plates 93 and limit cylinders 94. The limit push plates 93 are fixedly connected to the piston ends of the limit cylinders 94. Thus, under the operation drive of the limit cylinders 94, the pad printing jig 92 of the loading station 95 is clamped so that it is limited to a preset position, making it convenient for the material transfer nozzle 83 to place the sucked material onto the pad printing jig 92.

The visual lens 76 performs visual inspection on the material and determines whether the pad printing effect on the material meets the production requirements; the visual suction cup 77 can absorb the material, and then move the qualified material to the material conveyor belt 11 of the automatic bagging device through the visual mechanical arm 75. Alternatively, the unqualified material is moved to the defective product recovery station (not shown in the figure) for defective product recovery operation.

[0061] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
