Description

Technical Field

[0001] This utility model relates to the technical field of packaging equipment, and in particular to a fully automatic bag dispensing device. Background Technology

[0002] Filling machines are the core equipment for filling and sealing (capping) bottles. In traditional production scenarios, rotary filling machines are the mainstream. The core structure of a traditional rotary filling machine is a single turntable. All production processes, including filling, capping, and screwing on, must be completed within the circumference of the turntable. Currently, stand-up pouch filling machines on the market only have a simple chute at the outlet. For example, a food automatic bag filling and capping machine with Chinese utility model patent announcement number CN215664091U discloses a bag outlet component including a baffle. The baffle is connected to the base plate by a fixed rod, and a bag outlet chute is provided on one side of the baffle. Because the baffle and the slot are inclined, when the turntable drives the finished stand-up pouches to rotate, the finished stand-up pouches will slide out of the slot through the baffle and be sent into the collection box through the bag outlet chute. This method requires workers to manually sort and arrange the filled stand-up pouches before sending them in batches to the next workstation for the next process, such as sending them into a sterilization and disinfection equipment. This not only greatly increases the workload and labor costs but also reduces work efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model embodiment is to provide a fully automatic bag dispensing device, which realizes the fully automatic bag dispensing operation of self-standing bags and effectively improves the bag dispensing efficiency and accuracy.

[0004] To achieve the above objectives, this utility model discloses a fully automatic bag dispensing device, including a turntable, several grippers, and a bag pushing mechanism. The several grippers are equidistantly arranged on the outer periphery of the turntable in the circumferential direction for gripping stand-up pouches. The bag pushing mechanism is located on one side of the turntable. When the turntable drives the grippers past the bag pushing mechanism, the bag pushing mechanism pushes out the stand-up pouches from the grippers.

[0005] The gripper includes a first gripping part and a second gripping part arranged opposite to each other. The first gripping part and the second gripping part are elastically hinged to the turntable, and the hinge joint of the first gripping part and the second gripping part are linked together. An opening and closing guide mechanism is provided below the turntable, and the end of the first gripping part contacts and cooperates with the opening and closing guide mechanism.

[0006] When the gripper passes through the opening and closing guide mechanism, the first gripping part rotates outward relative to the second gripping part under the guidance of the opening and closing guide mechanism. When the gripper leaves the opening and closing guide mechanism, the first gripping part and the second gripping part rotate inward relative to each other under the elastic action, which is used to clamp the stand-up pouch.

[0007] Furthermore, the opening and closing guide mechanism includes an arc-shaped block, which is mounted below the turntable, and the end of the first clamping part is rotatably provided with a guide wheel that slides in cooperation with the arc-shaped block.

[0008] Furthermore, the bag pushing mechanism includes a plurality of push blocks and a rotary drive module. The plurality of push blocks are spaced apart along the length direction on the rotary drive module. The rotary drive module drives the plurality of push blocks to rotate, thereby pushing the stand-up pouch between the first clamping part and the second clamping part onto the conveyor belt.

[0009] Furthermore, it also includes a conveyor belt, with the turntable rotatably positioned in front of the beginning of the conveyor belt, and the bag pushing mechanism mounted above the front end of the conveyor belt, which pushes the stand-up pouches on the grippers onto the conveyor belt.

[0010] Furthermore, a first tray and a second tray are mounted above the beginning of the conveyor belt. There is a sliding channel between the first tray and the second tray for the stand-up pouch to pass through. The lower edges of the opposite surfaces of the first tray and the second tray are provided with flanges to support the bottle caps of the stand-up pouches.

[0011] Furthermore, the front inner sides of the first clamping part and the second clamping part are respectively provided with protruding edges for supporting the bottle cap of the stand-up pouch. When the protruding edges of the first clamping part and the second clamping part are connected with the flanges of the first tray and the second tray, the stand-up pouch between the first clamping part and the second clamping part is pushed into the sliding channel between the first tray and the second tray by the bag pushing mechanism.

[0012] Furthermore, several mounting plates are vertically hinged along the outer periphery of the turntable, and the first clamping part and the second clamping part are respectively hinged to the mounting plates. A support plate is provided below the turntable, and a support rod is provided at the bottom of the mounting plate, with the support rod acting on the support plate.

[0013] Furthermore, a weighing detection module is provided on the support plate, and the support rod contacts the weighing detection module so that the weighing detection module measures the weight of the stand-up pouch held by the gripper.

[0014] Furthermore, it also includes a fixed sleeve, in which a rotating shaft is rotatably disposed and fixedly connected to the turntable. An adjusting plate is disposed at the top of the fixed sleeve, and a plurality of arc-shaped grooves are equidistantly disposed on the surface of the adjusting plate along the circumference. A pair of adjusting rods fixedly connected to the arc-shaped grooves are disposed at the bottom of the arc-shaped block.

[0015] Furthermore, the hinge of the first clamping part is provided with a first tooth, and the hinge of the second clamping part is provided with a second tooth that meshes with the first tooth. The bottom of the first clamping part and the second clamping part are provided with a limiting shaft, and an elastic component is connected between the limiting shaft.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a more detailed description of this utility model in conjunction with the accompanying drawings.

[0027] Reference Figure 1 , Figure 2As shown, a fully automatic bag-dispensing device includes a turntable 1, several grippers 2, a bag-pushing mechanism 3, a conveyor belt 4, and a fixed sleeve 5. The turntable 1 is rotatably positioned in front of the first end of the conveyor belt 4. The fixed sleeve 5 is fixedly mounted on the frame (not shown in the figure). A rotating shaft is rotatably mounted inside the fixed sleeve 5 via bearings. The rotating shaft is fixedly connected to the turntable 1. Several grippers 2 are equidistantly arranged on the outer periphery of the turntable 1 in the circumferential direction for gripping stand-up pouches. A rotary drive device is fixedly mounted on the frame. In this embodiment, the rotary drive device preferably adopts a geared motor, whose output shaft is fixedly connected to the rotating shaft. The rotary drive device drives the turntable 1 to rotate, thereby passing through the turntable filling station and gripping the stand-up pouches that have been filled at the station. The bag-pushing mechanism 3 is located on one side of the turntable 1 and is mounted above the front end of the conveyor belt 4. The bag-pushing mechanism 3 pushes the stand-up pouches on the grippers 2 onto the conveyor belt 4, so that the conveyor belt 4 delivers the stand-up pouches to the designated station.

[0028] Reference Figure 3 , Figure 5 As shown, the gripper 2 includes a first gripping part 21 and a second gripping part 22 arranged opposite to each other. A plurality of mounting plates 11 are vertically hinged along the outer periphery of the turntable 1. The first gripping part 21 and the second gripping part 22 are respectively hinged to the mounting plates 11. An adjusting plate 51 is provided at the top of the fixed sleeve 5. A support plate 52 is provided below the turntable 1. The support plate 52 is fixedly connected to the bottom of the adjusting plate 51. A support rod 111 is provided at the bottom of the mounting plate 11. The support rod 111 acts on the support plate 52, thereby supporting the mounting plate 11 and keeping the mounting plate 11 and the turntable 1 on the same plane. The bottom of the first gripping part 21 and the second gripping part 22 is provided with a limiting shaft 231. An elastic component 24 is connected between the limiting shafts 231. In this embodiment, the elastic component 24 is preferably a tension spring, so that the first gripping part 21 and the second gripping part 22 are elastically hinged to the mounting plate 11 of the turntable 1.

[0029] Furthermore, the hinge of the first clamping part 21 is provided with a first tooth 211, and the hinge of the second clamping part 22 is provided with a second tooth 221 that meshes with the first tooth 211, so that the hinges of the first clamping part 21 and the second clamping part 22 are linked together, thereby ensuring that the first clamping part 21 and the second clamping part 22 can rotate relative to each other.

[0030] Reference Figure 3 , Figure 4As shown, further, an opening and closing guide mechanism 6 is mounted below the turntable 1. The end of the first clamping part 21 contacts and cooperates with the opening and closing guide mechanism 6. In this embodiment, the opening and closing guide mechanism 6 includes an arc-shaped block 61, which is mounted below the turntable 1. The end of the first clamping part 21 is rotatably provided with a guide wheel 212 that slides and cooperates with the arc-shaped block 61. The surface of the adjusting plate 51 is provided with a plurality of arc-shaped grooves 511 equidistantly arranged along the circumference. The bottom of the arc-shaped block 61 is provided with a pair of adjusting rods 62 that are fixedly connected to the arc-shaped grooves 511. In this embodiment, the adjusting rods 62 and the arc-shaped grooves 511 are... The fastening is achieved by using nuts. Therefore, by loosening the nuts, the adjusting rod 62 slides along the arc groove 511, allowing the grippers to adjust the position of the arc block 61 according to the desired position of opening or closing the stand-up pouch. After adjustment, the adjusting rod is locked. By adjusting the position of the arc block 61, the contact position and angle between the first clamping part 21 and the arc block 61 can be changed, flexibly adjusting the position and timing of the grippers opening and closing. This improves the versatility and adaptability of the fully automatic bag dispensing device, enabling it to better meet the bag dispensing requirements of different specifications and types of stand-up pouches.

[0031] When the first gripping part 21 of the gripper 2 passes the arc-shaped block 61 of the opening and closing guide mechanism 6, the guide wheel 212 slides along the surface of the arc-shaped block 61. During the sliding process of the guide wheel 212, the arc-shaped block 61 will exert a force on the first gripping part 21, causing the first gripping part 21 to rotate around the hinge, thereby linking the second gripping part 22 to rotate outward relative to each other, so that the gripper is in an open state, which facilitates the insertion or removal of the stand-up pouch.

[0032] When the guide wheel 212 of the first clamping part 21 of the gripper 2 leaves the arc-shaped block 61 of the opening and closing guide mechanism 6, the first clamping part 21 is reset under the elastic action of the elastic member 24, and the second clamping part 22 rotates inward relative to each other, so that the gripper 2 is in a clamping state and is used to clamp the stand-up pouch.

[0033] Reference Figure 2 , Figure 6 As shown, in this embodiment, protruding edges 23 are respectively provided on the inner front surfaces of the first clamping part 21 and the second clamping part 22. When the first clamping part 21 and the second clamping part 22 clamp the stand-up pouch, the protruding edges 23 of the first clamping part 21 and the second clamping part 22 support the bottle cap of the stand-up pouch. At this time, the protruding edges 23 can increase the contact area and friction with the bottle cap, making the stand-up pouch more stable during the clamping process and less likely to slip. Moreover, the protruding edges 23 can also play a certain limiting role for the stand-up pouch, preventing it from swaying or shifting during the clamping process. At the same time, the protruding edges 23 can also disperse the clamping force during the clamping process, avoiding damage to the bottle cap of the stand-up pouch due to excessive local pressure, ensuring the integrity and sealing of the stand-up pouch, thereby ensuring the quality of the product and the safety of subsequent use.

[0034] A weighing detection module 7 is provided on the support plate 52, and the weighing detection module 7 is located close to the bag exit position of the filling station. In this embodiment, the weighing detection module 7 preferably adopts a weighing sensor. When the turntable 1 rotates and drives the gripper 2 to pick up the stand-up pouch that has been filled at the filling station and passes through the weighing detection module 7, the support rod 111 on the mounting plate 11 contacts the weighing detection module 7, triggering the weighing sensor to start working. Since the mounting plate 11 and the turntable 1 are vertically hinged, the support rod 111 on the mounting plate 11 will generate a certain downward force under the influence of the weight of the stand-up pouch when the gripper 2 picks up the stand-up pouch. This allows the weighing detection module 7 to accurately measure the weight of the stand-up pouch picked up by the gripper 2 based on the force generated by the support rod 111. By comparing the measured weight with the preset standard weight, it can be determined whether the filling amount of the stand-up pouch meets the requirements. If the measured weight is within the reasonable error range of the standard weight, it indicates that the stand-up pouch is filled normally and can continue to complete the subsequent bag exit process through the bag pushing mechanism 3.

[0035] If the measured weight exceeds or falls below the reasonable range of the standard weight, it indicates that the stand-up pouch may have been filled too much or too little. In this case, a rejection mechanism is used to remove the unqualified stand-up pouches from the gripper 2 and transfer them to a specific recycling location to prevent them from flowing into the subsequent packaging process and to ensure the quality stability of the product. In this embodiment, the rejection mechanism can adopt the same structure as the bag pushing mechanism 3, which will not be repeated here.

[0036] Reference Figure 7 , Figure 8 As shown, further, the bag pushing mechanism 3 includes several push blocks 31 and a rotary drive module 32. The push blocks 31 are spaced apart along the length of the rotary drive module 32. A first support plate 41 and a second support plate 42 are mounted above the first end of the conveyor belt 4. Inverted "L"-shaped side plates 45 are respectively provided on both sides of the conveyor belt 4. The first support plate 41 and the second support plate 42 are fixedly connected to the inverted "L"-shaped side plates 45. There is a space between the first support plate 41 and the second support plate 42 for the self-standing bag. The sliding channel 43 is used for the self-standing bags. The lower edges of the opposite surfaces of the first tray 41 and the second tray 42 are provided with flanges 44. The rotary drive module 32 drives several push blocks 31 to rotate and push the self-standing bags on the grippers 2 into the sliding channel 43 between the first tray 41 and the second tray 42. The flanges 44 of the first tray 41 and the second tray 42 hold the bottle caps of the self-standing bags, so that the self-standing bags can be smoothly transferred from the first tray 41 and the second tray 42 to the conveyor belt 4.

[0037] Even better, the height between the first pallet 41, the second pallet 42, and the conveyor belt 4 is approximately the same as the height of the stand-up pouch, preventing the pouch from tipping over or swaying due to excessive height difference during transport and ensuring stability. Simultaneously, due to the height compatibility, the bottle cap maintains good contact with the flange as the pouch slides within the sliding channel, further enhancing the cap-holding effect and preventing damage from collisions or compression during transport. Furthermore, when the pusher block 31 propels the pouch forward under the drive of the rotary drive module 32, the suitable height difference allows the pusher block 31 to act more smoothly on the pouch, avoiding problems such as inability to push due to unsuitable height or abnormal pouch posture during pushing, thus improving the efficiency and reliability of the pouch-pushing mechanism.

[0038] In this embodiment, the inverted "L"-shaped side plate 45 is provided with a pair of strip holes and is fixedly connected to the side wall of the conveyor belt 4 by adjusting bolts, so that the height of the inverted "L"-shaped side plate 45 can be flexibly adjusted according to the specific size of the stand-up pouch to meet the production needs of stand-up pouches of different specifications.

[0039] Specifically, in this embodiment, the rotary drive module 32 consists of a synchronous belt 321, a first synchronous pulley 322, and a second synchronous pulley 323. A corner bracket is fixedly installed on the second support plate 42, and a push-bag mounting plate is fixedly installed on the corner bracket. The first synchronous pulley 322 and the second synchronous pulley 323 are respectively rotatably mounted on the push-bag mounting plate. The synchronous belt 321 is tensioned between the first synchronous pulley 322 and the second synchronous pulley 323. Several push blocks 31 are fixedly connected to the synchronous belt 321. A push-bag drive device is fixedly installed on the push-bag mounting plate. In this embodiment, the push-bag drive device preferably adopts a servo motor, whose output shaft is fixedly connected to the first synchronous pulley 322. In this way, the push-bag drive device drives the synchronous belt 321 to drive the several push blocks 31 to rotate.

[0040] Reference Figures 1-8As shown, in specific operation, the turntable 1 drives several grippers 2 to sequentially grip the stand-up pouches on the turntable filling station, and then drives several grippers 2 to sequentially transport the stand-up pouches to the beginning of the conveyor belt 4, so that the protruding edges 23 on the first gripping part 21 and the second gripping part 22 connect with the flanges 44 of the first tray 41 and the second tray 42. In this way, the pusher drive device drives the synchronous belt 321 to drive the pusher block 31 to rotate, so that the pusher block 31 enters between the first gripping part 21 and the second gripping part 22 of the gripper 2, thereby pushing the bottle cap of the stand-up pouch to slide along the protruding edge 23 of the gripper 2 into the space between the first tray 41 and the second tray 42, and using the first... The flanges 44 of the first tray 41 and the second tray 42 hold the bottle cap of the stand-up pouch. As the pusher block 31 continues to move, the stand-up pouch on the gripper 2 is continuously pushed into the sliding channel 43. Under the push of the pusher block 31, the stand-up pouch moves along the sliding channel 43 until it is pushed out of the sliding channel 43 and falls into the conveyor belt 4. This keeps the stand-up pouch upright during the conveying process, avoiding the problem of the stand-up pouch tipping over or deforming. Then, the stand-up pouch is sent to the subsequent packaging, labeling and other processes by the conveyor belt 4, thus completing the entire fully automatic bag output process. This achieves efficient and stable conveying of stand-up pouches, greatly improves production efficiency and reduces labor costs.

Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly.
