Description

Technical Field

[0001] This utility model relates to pharmaceutical packaging machinery, and more particularly to an automatic empty bag rejection mechanism for an intelligent bag-feeding packaging machine. Background Technology

[0002] This utility model patent aims to address the technical deficiencies of existing bag-feeding automatic packaging machines. As a key production equipment for pharmaceutical companies, bag-feeding automatic packaging machines rely on a PLC control system and precision components such as servo motors working in tandem. The bag-feeding mechanism provides packaging bags to the mechanical grippers, the servo motor drives the turntable to rotate, the turntable drives multiple mechanical grippers to rotate, and the bag-opening mechanism is used to open the packaging bags held on the mechanical grippers. Automated packaging is achieved through the combination of the turntable, mechanical grippers, bag-opening mechanism, heat-sealing mechanism, and bag-feeding mechanism. However, in practical applications, Guangxi Baiyunshan Yingkang Pharmaceutical Co., Ltd. found that when using this equipment to package granules such as Vitamin C Yinqiao Granules, Juhong Tan Ke Granules, Shenmei Yangwei Granules, and Huoxiang Zhengqi Granules, the equipment was prone to empty bag problems due to occasional malfunctions in components such as the material supply system, bag supply system, and bag-opening mechanism. Because existing equipment cannot remove empty bags before packaging, empty bags flow into the heat-sealing process, causing the packaging bags to be scrapped and unable to be recycled, resulting in a packaging material loss rate as high as 10% to 15%, significantly increasing production costs and reducing production efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an intelligent bag-feeding packaging machine with an automatic empty bag rejection mechanism.

[0008] Furthermore, the intelligent bag-feeding packaging machine's automatic empty bag rejection mechanism of this utility model also includes limiting rings, with limiting rings installed at both ends of the base cylinder.

[0009] Furthermore, the intelligent bag-feeding packaging machine's automatic empty bag rejection mechanism of this utility model also includes a first support ring and a second support ring. The first support ring and the second support ring are spaced apart and sleeved on the push rod. The first support ring is fixed to the support cylinder and is used to support one end of the second spring.

[0010] Furthermore, the clamp release assembly includes a base, an extension frame mounted on one side of the top of the base; a swing frame, the swing frame including a horizontal frame and a diagonal brace, one end of the diagonal brace extending upwards and connecting to a push plate, and the other end bent and connected to the horizontal frame, the horizontal frame being connected to the base via two swing support members; a sleeve, the sleeve being mounted on the diagonal brace via a fourth shaft; a rotating cylinder, the rotating cylinder being rotatably mounted on the extension frame; and a V-shaped frame, the V-shaped frame being mounted on the rotating cylinder and extending outwards in a V-shape relative to the rotating cylinder with two legs, one leg being connected to the rotating cylinder and the other leg being connected to a drive member for transmission.

[0011] Furthermore, the swing support includes a first fixed shaft mounted on a horizontal frame; a second fixed shaft mounted on a base; and a screw, one end of which is provided with a first collar, and the other end of which is provided with a second nut and housed in a storage cylinder, the screw being threadedly connected to the second nut and the storage cylinder; the storage cylinder is fitted with the second fixed shaft.

[0012] Furthermore, the intelligent bag-feeding packaging machine's automatic empty bag rejection mechanism of this utility model also includes a first nut and a third nut, wherein the first nut is threadedly connected to a first fixed shaft, and the third nut is threadedly connected to a second fixed shaft.

[0015] The present invention represents a significant advancement over the prior art:

[0016] 1. This utility model innovatively constructs a highly efficient empty bag rejection mechanism, achieving precise unloading of empty bags through precise coordinated operation. In the packaging process, a turntable drives the bag clamping assembly in a circular motion, causing the packaging bags to flow synchronously. When the detection component monitors the incoming packaging bags in real time, once an empty bag is identified, the controller immediately initiates a response program, precisely controlling the release clamping assembly to perform its action. The release clamping assembly, through mechanical transmission, drives the bag clamping assembly to quickly release its grip on the empty bag, allowing the empty bag to fall freely under gravity, completely detaching from the bag clamping assembly. This completes the rejection of empty bags before the sealing process, eliminating the occurrence of empty packaging at the source.

[0017] 2. This invention moves the empty bag rejection process before the heat sealing process, effectively avoiding irreversible waste of empty packaging bags caused by entering the heat sealing process. Compared with traditional packaging equipment, the rejected empty packaging bags remain intact, ensuring recycling and significantly reducing packaging material waste. This not only significantly reduces enterprise production costs but also aligns with the concept of green production, achieving efficient resource utilization and sustainable development in the packaging production process.

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions of this utility model will be clearly and completely described below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments in this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0030] Example 1:

[0031] like Figure 1-5 As shown, this utility model discloses an automatic empty bag rejection mechanism for an intelligent bag-feeding packaging machine, which can be applied to automatic bag-feeding packaging machines.

[0032] like Figure 1-5The diagram shows a structure of this utility model installed on a bag-packing machine. Existing bag-packing machines include a feeding hopper 2, a worktable 103, a drive mechanism, a sealing mechanism, and a turntable 101. Multiple bag clamping assemblies 7 are distributed circumferentially on the turntable 101. The worktable 103 supports and mounts a support cylinder 102, clamp release assemblies 7, detection assemblies 6, and the sealing mechanism, while the feeding hopper 2 is installed close to the turntable 101. To remove empty bags, clamp release assemblies 7, detection assemblies 6, and a controller 3 are added. The clamp release assemblies 7 and detection assemblies 6 are located between the feeding hopper 2 and the sealing mechanism. The feeding hopper 2 feeds material to the opened packaging bags. The drive mechanism drives the turntable 101 to rotate, and the turntable 101 drives the bag clamping assemblies 7 to rotate from the feeding hopper 2 towards the sealing mechanism. The detection assemblies 6 are used to detect whether the packaging bags clamped on the bag clamping assemblies 7 are empty. Clamp release assemblies 5 are spaced apart from the detection assemblies 6. The controller 3 is electrically connected to the detection assemblies 6 and the clamp release assemblies 5. While the bag clamp assembly 7 is clamping and rotating the packaging bag, the detection assembly 6 visually detects whether any material is falling. When no material is detected, it sends a no-material data signal to the controller 3. As the packaging bag rotates with the bag clamp assembly 7, it touches the detection assembly 6. The detection assembly 6 then sends a positioning data signal to the controller 3. The controller 3 controls the release assembly 5 to work, and the release assembly 5 drives the bag clamp assembly 7 to release the empty packaging bag, thereby removing the empty packaging bag.

[0033] The detection component 6 has both visual monitoring and touch sensing capabilities, and can be divided into a visual monitoring end and a touch sensing end. The visual monitoring end can be installed in the feed hopper 2 (e.g., ...). Figure 1 As shown), it detects whether there is material falling from the feed hopper 2; the touch sensor can be installed on the worktable corresponding to the clamping assembly 5.

[0034] Understandably, the bag-opening station on the packaging machine cannot effectively open the packaging bags. When the packaging bag rotates to the feeding station, the feeding station detects that the packaging bag has not been opened and therefore does not feed it, resulting in empty packaging. This utility model removes empty packaging bags before they rotate to the heat-sealing station, preventing empty packaging bags from being heat-sealed and wasting them.

[0035] like Figure 1 , 2 As shown, the pocket clip assembly 7 includes two pocket clips and a third spring 714, with the two pocket clips connected by the third spring 714. The third spring 714 can be used to define the positional interval between the two pocket clips.

[0036] like Figure 2 As shown, each bag clip is equipped with a spring connecting rod 719. The two ends of the third spring 714 are mounted on the bag clip via the spring connecting rod 719.

[0037] To guide the rotation of the packaging bags, a bag guide 4 is added. The bag guide 4 has an arc-shaped structure and is located below the turntable 101. The bag guide 4 includes an arc-shaped rod 41 and a bracket 42. The arc-shaped rod 41 extends in accordance with the circumferential rotation of the turntable and is mounted on the worktable 101 by multiple brackets 42.

[0038] A type of pocket clip structure, such as Figure 2 , 4 As shown, the bag clamp includes a support shaft 712, a base cylinder 713, a support cylinder 77, a movable clamp 71, a push rod 76, and a vertical rod 715. A guide plate 718 is mounted on one end of the support shaft 712, and the guide plate 718 has a guide groove 7181. The base cylinder 713 is fitted with the support shaft 712. One end of the support cylinder 77 is mounted on the base cylinder 713, and the other end has a fixed clamp 75, with a sliding groove 771 corresponding to the guide groove 7181. The movable clamp 71 is movably connected to the fixed clamp 75. A second spring 79 is fitted onto the push rod 76 and placed inside the support cylinder 77. One end extends out of the support cylinder 77 and passes through the fixed clamp 75, hinged to the movable clamp 71. One end of the second spring 79 is connected to the support cylinder 77, and the other end is connected to the push rod 76. One end of the vertical rod 715 is inserted into the sliding groove 771 and connected to the push rod 76, and the other end passes through the guide groove 7181 and is connected to the rotating component 717.

[0039] The rotating component 717 can rotate relative to the vertical rod 715. One structure of the rotating component 717 can be a rubber roller structure. When the push plate pushes the rotating component, the rotating component can roll into contact with the push plate, so the drive mechanism can be stopped to drive the turntable to rotate.

[0040] When the vertical rod 715 pushes the push rod 76 to slide within the support cylinder 77, the push rod 76 causes the second spring 79 to undergo elastic deformation, thus possessing elastic potential energy. When the applied force on the vertical rod 715 is released, the second spring 79 elastically resets itself, simultaneously pushing the vertical rod 715 to move in the opposite direction within the support cylinder 77 to reset.

[0041] A movable connection structure between the movable clamp 71 and the fixed clamp 75: The fixed clamp 75 is provided with two spaced and aligned support seats 73, one end of the movable clamp 71 is placed between the two support seats 73, and a first rotating shaft 74 passes through one support seat, the movable clamp, and the other support seat in sequence. The movable clamp 71 can swing relative to the fixed clamp by means of the first rotating shaft 74.

[0042] A hinged connection structure between the push rod and the movable clamp 71: The movable clamp 71 is provided with a clamp seat 72, and the clamp seat 72 is connected to the push rod 76 through a pivot. The movable clamp can swing relative to the push rod 76 through the pivot.

[0043] In some alternative embodiments, a connection structure for the base cylinder is provided, which includes the installation of limiting rings 711. Limiting rings 711 are installed at both ends of the base cylinder 713. The limiting ring 711 installed on the top of the base cylinder 713 can be supported by the turntable 101, and the limiting ring installed on the bottom can overlap with the guide plate.

[0044] like Figure 4 As shown, in order to further strengthen the support of the guide plate, an anti-detachment component 720 is added, and the support shaft 712 passes through the guide plate 718 and is connected to the anti-detachment component 720.

[0045] The anti-detachment component 720 can be a screw with a nut. The anti-detachment component is threadedly connected to the support shaft 712. The nut can support the guide plate 718 and provide support force for the guide plate.

[0046] In some optional embodiments, a connection structure between the second spring and the support cylinder is provided, with the addition of a first support ring 78 and a second support ring 710. The first support ring 78 and the second support ring 710 are spaced apart and sleeved on the push rod 76. The first support ring 78 is fixed to the support cylinder 77 and is used to support one end of the second spring 79; the second support ring 710 is fixedly connected to the push rod 76 and is used to support the other end of the second spring 79.

[0047] The first support ring 78 and the second support ring 710 are located inside the support cylinder 77 and can also help restrict the movement of the push rod 76.

[0048] In some alternative embodiments, one structure of the release clamp assembly is provided. The release clamp assembly 5 includes a base 512, a sleeve 52, a rotating cylinder 515, a swing frame 53, and a V-shaped frame 516. An extension frame 513 is mounted on one side of the top of the base 512; the swing frame includes a horizontal frame 531 and a diagonal support frame 532, one end of the diagonal support frame 532 extends upward at an angle and connects to the push plate 51, and the other end is bent and connected to the horizontal frame 531. The horizontal frame 531 and the base 512 are connected by two swing support members; the sleeve 52 is mounted on the diagonal support frame 532 via a fourth shaft 519; the rotating cylinder 515 is rotatably mounted on the extension frame 513; the V-shaped frame 516 is mounted on the rotating cylinder 515 and extends outward in a V-shape relative to the rotating cylinder 515 with two legs, one leg connected to the rotating cylinder 515 and the other leg connected to the drive member 514.

[0049] like Figure 3 As shown, the V-shaped frame 516 includes a first leg 5161 and a second leg 5162. The first leg 5161 is used for transmission connection with the drive unit 514, and the second leg 5162 is connected to the rotating drum 515.

[0050] The swing support includes a first fixed shaft 54, a second fixed shaft 511, and a screw 57. The first fixed shaft 54 ​​is mounted on a horizontal frame 531. The second fixed shaft 511 is mounted on a base 512. One end of the screw 57 has a first collar 55, and the other end has a second nut 58 that passes through it and is housed in a housing spool 59. The screw 57 is threadedly connected to the second nut 58 and the housing spool 59. The housing spool 59 is fitted onto the second fixed shaft 511.

[0051] like Figure 2 , 3 As shown, two swing supports support the swing frame 53 and are spaced apart from the top of the base 512. The swing supports are installed at an angle to support the swing of the swing frame.

[0052] To further define the first collar and the storage tube, a first nut 56 and a third nut 510 are added. The first nut 56 is threaded to the first fixed shaft 54, and the third nut 510 is threaded to the second fixed shaft 511.

[0053] The first nut 56 can restrict the first collar 55 to be stably installed on the first fixed shaft 54. This can prevent the first collar from disengaging from the first fixed shaft during the swinging of the swing support.

[0054] The third nut 56 can restrict the storage tube 59 to be stably installed on the second fixed shaft 511, and can prevent the storage tube from disengaging from the second fixed shaft during the swing of the swing support.

[0055] In some optional embodiments, a drive connection structure between the drive member and the V-shaped bracket is provided, which includes the addition of a second collar 518 and a third fixed shaft 517. The third fixed shaft 517 is mounted on the V-shaped bracket 516, and the drive member 514 is provided with a piston 5141. The piston 5141 is provided with a second collar 518, which is fitted onto the third fixed shaft 517.

[0056] The drive unit can be a pneumatic cylinder or a hydraulic cylinder. The appropriate drive unit can be selected based on the specific work requirements.

[0057] To restrict the second collar 518 to the third fixed shaft 517, a fourth nut 520 is added. The fourth nut 520 is threaded to the third fixed shaft 517, which can restrict the second collar 518 to the third fixed shaft 517, and facilitate the piston 5141 to drive the third fixed shaft to move.

[0058] like Figure 2 , 3As shown, during operation, the drive unit 514 drives the piston 5141 to retract downwards. The piston 5141 causes the first leg 5161 of the V-shaped frame 516 to swing downwards. The V-shaped frame 516 can rotate with the help of the rotating cylinder 515. At the same time, the second leg 5162 on the V-shaped frame 516 swings towards the piston 5141, causing the rotating cylinder 515, the swing frame 53 and the swing support to swing towards the piston 5141. The swing frame 53 drives the push plate 51 to move forward. The push plate 51 simultaneously pushes the two rotating parts 717 on the bag clamp assembly 7. The pushed rotating parts move along the guide groove 7181. The driving component 514 drives the piston 5141 to extend upward and reset. The piston 5141 drives the first leg 5161 of the V-shaped frame 516 to swing upward. The V-shaped frame 516 can rotate with the help of the rotating cylinder 515. While the second leg 5162 on the V-shaped frame 516 swings away from the piston 5141, it drives the rotating cylinder 515, the swing frame 53 and the swing support to swing away from the piston 5141. The swing frame 53 drives the push plate 51 to move backward and reset. The push plate 51 then disengages from the rotating component 717 on the bag clamp assembly 7.

[0059] In some alternative embodiments, one structure of the detection component is provided, such as... Figure 2 , 5 As shown, the detection assembly includes a support platform 61, a rotating shaft 611, a vision sensor 613, and a first spring 64. A proximity sensor 66 and a support 610 are mounted on the support platform 61. The rotating shaft 611 passes through the support 610, with a first rotating cap 68 mounted at one end and a second rotating cap 612 mounted at the other end. A first swing member 67 is mounted on one side of the first rotating cap 68, and a trigger plate 69 is mounted on the other side. A second swing member 65, rotating in the same direction as the first swing member 67, is mounted on the second rotating cap 612. One end of the first spring 64 is connected to the second swing member 65, and the other end is mounted on the support platform 61. The vision sensor 613 is used to detect whether there is falling material. Both the proximity sensor 66 and the vision sensor 613 are electrically connected to the controller 3.

[0060] As the packaging bag rotates with the bag clamp assembly 7, it collides with the trigger plate 69, causing the trigger plate 69 to swing. The trigger plate then drives the first rotating cap 68 to rotate, which in turn drives the first swinging member 67 and the rotating shaft 611 to rotate. The rotating shaft 611 drives the second rotating cap 612 to rotate, and the second rotating cap 612 drives the second swinging member 65 to swing. When the second swinging member 65 swings, it causes the first spring 64 to undergo elastic deformation. The first spring 64 has elastic potential energy. After the packaging bag rotates and disengages from the trigger plate 69, the first spring 64 drives the second swinging member 65 to quickly move in the opposite direction and reset. The second swinging member drives the rotating shaft 611 to quickly reverse, and the rotating shaft 611 drives the first rotating cap 68 to rotate quickly in the opposite direction. The first rotating cap 68 drives the first swinging member 67 to swing quickly in the opposite direction and re-adhere to the sensing surface of the proximity sensor 66.

[0061] Initially, the first swing member 67 is in contact with the sensing surface of the proximity sensor 66. The proximity sensor is electrically connected to the controller 3. When the first swing member 67 is driven to deviate from the sensing surface of the proximity sensor, the proximity sensor is triggered to work (meaning that the bag clamp assembly drives the packaging bag to rotate to the touch sensing end of the detection assembly). The proximity sensor immediately sends data information to the controller, and the controller controls the release assembly 5 to work upon receiving the data information.

[0062] An installation structure for the support platform 61: The support platform 61 is fixedly installed on the support platform by multiple legs 62.

[0063] To facilitate the mounting of the first spring 64 onto the support platform 61, a hook rod 63 is added, which is mounted on the support platform to support one end of the first spring 64.

[0064] In the detection component of this utility model, the visual monitoring end and the touch sensing end interact with each other. The visual monitoring end monitors in real time whether material falls into the feeding hopper. When it detects that no material is falling from the feeding hopper (the packaging bag is not filled with material and is in an empty bag state), it can send a data signal of no material falling to the controller. The controller 3 receives the data signal and performs analysis and processing. As the turntable drives the bag clamping assembly to rotate, the bag clamping assembly drives the empty packaging bag to rotate and touch the touch sensing end. The touch sensing end (which can be used for positioning) sends data information to the controller. The controller controls the release clamping assembly to work, and the release clamping assembly drives the bag clamping assembly to release the packaging bag.

[0065] According to the above embodiments, the working method of this utility model is as follows:

[0066] Turntable 101 drives bag clamp assembly 7 from bag opening station to feeding station (feeding hopper 2), and then to detection assembly 6. Vision sensor 613 on detection assembly 6 is installed in feeding hopper 2. The bag touches and squeezes trigger plate 69 to swing. Trigger plate 69 drives first rotating cap 68 to rotate. First rotating cap 68 drives first swinging member 67 and rotating shaft 611 to rotate. Rotating shaft 611 drives second rotating cap 612 to rotate. Second rotating cap 612 drives second swinging member 65 to swing. When second swinging member 65 swings, it drives first spring 64 to generate elastic deformation. First spring 64 has elastic potential energy.

[0067] If the first swinging component 67 deviates from the sensing surface of the proximity sensor, it indicates that the empty packaging bag driven by the bag clamp assembly 7 has rotated to the touch sensing end (proximity sensor 66) of the detection assembly 6. The proximity sensor 66 immediately sends data information to the controller 3. Upon receiving the data information, the controller controls the drive component 514 to operate. The drive component 514 drives the piston 5141 to retract downward. The piston 5141 drives the first leg 5161 of the V-shaped frame 516 to swing downward. The V-shaped frame 516 can rotate with the help of the rotating drum 515. At the same time, the second leg 5162 on the V-shaped frame 516 swings towards the piston 5141, driving the rotating drum 515, the swinging frame 53, and the... The swing support swings toward the piston 5141, and the swing frame 53 drives the push plate 51 to move forward. The push plate 51 simultaneously pushes the two rotating parts 717 on the bag clamp assembly 7. The pushed rotating parts 717 move along the guide groove 7181. While the rotating parts 717 drive the vertical rod 715 to move along the guide groove 7181, the vertical rod 715 drives the push rod 76 to extend outward toward the support cylinder 77. The push rod 76 pushes the movable claw 71 to swing outward relative to the fixed claw 75. The movable claw 71 and the fixed claw 75 open, and the movable claw 71 and the fixed claw 75 release the packaging bag. The packaging bag detaches from the movable claw and the fixed claw under its own gravity, thus removing the empty bag.

[0068] When piston 5141 retracts to its set stroke, it automatically resets. Driven by drive member 514, piston 5141 extends upward to reset. Piston 5141 drives the first leg 5161 of V-shaped frame 516 to swing upward. V-shaped frame 516 can rotate with the help of rotating drum 515. While the second leg 5162 on V-shaped frame 516 swings away from piston 5141, it drives rotating drum 515, swing frame 53 and swing support to swing away from piston 5141. Swing frame 53 drives push plate 51 to move backward to reset. Push plate 51 then disengages from rotating member 717 on bag clamp assembly 7, thus completing the removal of empty packaging bag.

[0069] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
