Description

Technical Field

[0001] This application relates to the field of product packaging technology, and in particular to a packaging bag separation and transfer device. Background Technology

[0002] In modern enterprise production, before packaging products, stacked packaging bags need to be separated one by one and transferred to a designated location. As an important carrier of product packaging, the accuracy and speed of the separation and transfer of packaging bags directly affect the continuity of subsequent packaging processes and the stability of product quality. Therefore, the efficient and stable separation and transfer of packaging bags has become an important link in improving production efficiency.

[0003] In existing technologies, the following methods are commonly used to separate and transfer packaging bags: one method involves manually separating stacked bags one by one and then transferring them to a designated location. This method relies entirely on manual intervention, offering high flexibility but low efficiency. Another method combines mechanisms such as vibrating screens or inclined chutes to separate the bags one by one using gravity or vibration, followed by transfer via conveyor belts. This method is prone to simultaneous separation of multiple tightly stacked bags. While these methods can meet the needs of packaging bag separation and transfer to some extent, they still have many limitations in practical applications.

[0004] Regarding the aforementioned technologies, the inventors believe that existing methods for separating and transferring packaging bags generally suffer from low separation accuracy and low transfer efficiency. Utility Model Content

[0005] In order to improve the separation accuracy and transfer efficiency of stacked packaging bags during separation and transfer, this application provides a packaging bag separation and transfer device.

[0006] The packaging bag separation and transfer device provided in this application adopts the following technical solution:

[0007] A packaging bag separation and transfer device includes a separation mechanism, a transport mechanism, and a transfer mechanism located between the separation mechanism and the transport mechanism; the separation mechanism includes a storage box for placing packaging bags and a suction component that is lifted and lowered at the bottom of the storage box for picking up individual packaging bags; the transfer mechanism includes a transfer frame, a first drive component disposed on the transfer frame, and a robotic arm connected to the first drive component for gripping packaging bags, wherein the first drive component drives the robotic arm to move back and forth between the separation mechanism and the transport mechanism.

[0008] By adopting the above technical solution, a separation mechanism, a transfer mechanism, and a carrier mechanism are set up. The suction component in the separation mechanism can accurately separate the packaging bags, reducing the probability of multiple packaging bags being separated simultaneously, thereby improving separation accuracy. Driven by the first drive component, the robotic arm in the transfer mechanism can stably clamp and transfer the separated packaging bags to the carrier mechanism, ensuring the efficiency and reliability of the transfer process. The entire device realizes integrated operation from packaging bag separation to transfer, improving the accuracy of separating stacked packaging bags and the efficiency of transfer, thus ensuring the continuity of subsequent packaging processes and the stability of product quality.

[0009] Optionally, the first drive assembly includes a drive motor, a swing arm hinged to the manipulator and connected to the output end of the drive motor, and a connecting rod with its two ends respectively hinged to the manipulator and the transfer frame.

[0010] By adopting the above technical solution, the specific composition of the first drive assembly is disclosed. The first drive assembly includes a drive motor, a swing arm, and a connecting rod. The drive motor drives the swing arm to rotate, thereby driving the robot. The setting of the connecting rod ensures the stability and accuracy of the robot's movement. The cooperation of the drive motor, the swing arm, and the connecting rod enables the robot to achieve precise reciprocating movement between the separation mechanism and the transport mechanism.

[0011] Optionally, the robotic arm is provided with a first gripper, a second gripper, and a first clamping drive for driving the first gripper to rotate, with the first gripper and the second gripper being configured correspondingly.

[0012] By adopting the above technical solution, the specific structure of the robotic arm is disclosed. The robotic arm achieves precise gripping of the packaging bag by setting a first gripper, a second gripper, and a first gripping drive component. The first gripping drive component drives the first gripper to rotate, which cooperates with the second gripper to complete the gripping action of the packaging bag, ensuring stable and reliable gripping and helping to improve the accuracy of packaging bag separation and transfer.

[0013] Optionally, the suction component is a vacuum suction cup, and the separation mechanism further includes a support plate located above the vacuum suction cup and used to support the storage bag box. A limiting member for abutting the packaging bag is slidably installed on the support plate, and a locking member is provided on the support plate. A locking groove that cooperates with the locking member is provided on the limiting member. The top of the storage bag box has an inclined surface that slopes downward toward the limiting member.

[0014] By adopting the above technical solution, the vacuum suction cup can accurately pick up a single packaging bag, avoiding the simultaneous picking up of multiple packaging bags and thus improving separation accuracy. The limiting components on the support plate, through sliding installation and locking engagement, help improve the stability of the stacked packaging bags and allow for flexible position adjustment to accommodate stacks of packaging bags of different sizes. The inclined surface on the top of the storage box facilitates the addition of packaging bags by the operator.

[0015] Optionally, the separation mechanism is provided with a lifting drive assembly at the bottom of the support plate. The lifting drive assembly includes two guide columns connected to the bottom side of the support plate, a lifting platform that slides and moves up and down on the guide columns, and a second drive component that drives the lifting platform to move up and down. The vacuum suction cup is provided on the lifting platform.

[0016] By adopting the above technical solution, the specific structure of the lifting drive assembly is disclosed. The lifting drive assembly enables the vacuum suction cup to move up and down precisely under the guidance of the guide columns, ensuring that the vacuum suction cup accurately picks up a single packaging bag and avoids the situation where multiple packaging bags are picked up at the same time, thereby improving the separation accuracy. The design of two guide columns ensures the stability of the lifting process and avoids tilting or jamming problems caused by uneven force on one side, further improving the reliability of the separation process.

[0017] Optionally, the vacuum suction cup and the end of the packaging bag near the transfer mechanism are corresponding. The top of the support plate is provided with a pressing component for pressing the packaging bag. The pressing component includes a pressing plate, a pressing drive for driving the pressing plate to rise and fall, and a support frame for supporting the pressing drive. The pressing plate is provided with a sensor for detecting the distance from the bottom surface of the pressing plate to the top surface of the stacked packaging bags.

[0018] By adopting the above technical solution, since the vacuum suction cup and the end of the packaging bag closest to the transfer mechanism correspond, the side of the packaging bag facing the transfer mechanism is relatively flat after the vacuum suction cup picks up a packaging bag. It will not tilt downward due to gravity, which helps the robot arm to accurately grip the packaging bag. At the same time, a pressure holding component and a sensor are set up. When there is a gap between the bottom surface of the pressure holding plate and the top surface of the packaging bag, the pressure holding drive will drive the pressure holding plate to descend and press the packaging bag, reducing the probability that the suction component will lift the packaging bag and fail to pick it up when there are few packaging bags.

[0019] Optionally, the carrier mechanism includes a carrier tray, a third driving member for driving the carrier tray to rotate, and a plurality of carrier clamping assemblies that are circumferentially mounted on the carrier tray at uniform intervals and are used to receive and clamp the packaging bags.

[0020] By adopting the above technical solution, the transport tray rotates under the drive of the third driving component, enabling it to orderly receive and transfer multiple packaging bags to a designated location, significantly improving the efficiency of packaging bag transfer. Several evenly spaced, circumferentially installed transport clamping components on the transport tray ensure that each packaging bag is firmly clamped, preventing it from falling off or shifting during transfer, thereby improving the continuity and reliability of packaging bag transfer.

[0021] Optionally, the carrier clamping assembly includes two sets of carrier rods disposed on the carrier tray, carrier clamping claws rotatably mounted on the ends of the carrier rods, and a carrier drive assembly for driving the carrier clamping claws to rotate and open.

[0022] By adopting the above technical solution, since the carrier clamping assembly includes a carrier rod, a carrier clamping claw, and a carrier drive assembly, the carrier rod is set on the carrier plate, the carrier clamping claw is installed at the end of the carrier rod, and the carrier drive assembly can drive the carrier clamping claw to rotate and open, so that the clamping claw can accurately receive the packaging bag after it rotates and opens.

[0023] Optionally, the transport drive assembly includes a push rod slidably mounted on the transport rod and used to push the transport gripper, a return spring connected to the push rod, and a transport drive component disposed at the bottom of the transport tray. The push rod is provided with a push post corresponding to the transport drive component.

[0024] By adopting the above technical solution, the specific structure of the carrier drive assembly is disclosed. The structural design of the carrier drive assembly enables the carrier gripper to achieve precise and stable opening and closing actions. Specifically, the push rod is slidably installed on the carrier rod, and can accurately drive the carrier gripper to rotate and open through the action of the carrier drive component, thereby realizing the placement of the packaging bag; the setting of the return spring ensures that the carrier gripper can automatically return to its closed state when the external force is lost, firmly gripping the packaging bag and preventing it from falling off during transportation; the setting of the push column further improves the matching accuracy between the push rod and the carrier drive component, and enhances the reliability of the overall action. This design effectively improves the transportation efficiency and stability of the packaging bag, and reduces the probability of the packaging bag falling off due to unstable gripping.

[0025] Optionally, the output end of the carrier drive component is also provided with a limiting frame for positioning the packaging bag.

[0026] By adopting the above technical solution, the packaging bag can be accurately positioned within the carrier. Specifically, the limiting frame ensures that the packaging bag is stably abutted after being received by the carrier clamping component, avoiding transfer failures or subsequent process abnormalities caused by positional deviations, thereby improving the reliability of packaging bag transfer.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. A packaging bag separation and transfer device, which integrates a separation mechanism, a transfer mechanism and a carrier mechanism, and realizes the integrated operation of packaging bag separation and transfer, thereby improving the accuracy of separating stacked packaging bags and the efficiency of transfer.

[0029] 2. By setting a drive motor, a swing arm and a connecting rod in the first drive assembly, the setting of the connecting rod ensures the stability and accuracy of the robot's movement. The cooperation of the drive motor, the swing arm and the connecting rod enables the robot to make precise reciprocating movements between the separation mechanism and the transport mechanism.

[0030] 3. By setting a limiting component on the support plate, the limiting component is slidably installed on the support plate and can be locked in place, which helps to improve the stability of the stacking of packaging bags, and at the same time, the position can be flexibly adjusted to accommodate the stacking of packaging bags of different sizes.

[0037] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0038] This application discloses a packaging bag separation and transfer device. (Refer to...) Figure 1 The packaging bag separation and transfer device includes a separation mechanism 1, a transport mechanism 2, and a transfer mechanism 3 located between the separation mechanism 1 and the transport mechanism 2. The separation mechanism 1 includes, from bottom to top, a lifting drive assembly 11, a suction assembly 12, a support plate 13, and a bag storage box 14. The lifting drive assembly 11 includes two guide columns 111 connected to the bottom surface of the support plate 13, a lifting platform 112 that slides and moves along the guide columns 111, and a second drive component 113 that drives the lifting platform 112 to move up and down. In this embodiment, the suction assembly 12 is a vacuum suction cup of the prior art, and the vacuum suction cup is disposed on the lifting platform 112.

[0039] refer to Figure 1 and Figure 2 The storage bag box 14 is used to hold packaging bags. The storage bag box 14 and the support plate 13 are provided with a separation groove 141 for the vacuum suction cup to pass through. The vacuum suction cup and the packaging bag correspond to the end of the packaging bag near the transfer mechanism 3. The second driving member 113 drives the lifting platform 112 to rise, thereby driving the vacuum suction cup to rise, so that the vacuum suction cup can pick up a single packaging bag. Then the second driving member 113 drives the lifting platform 112 to fall, thereby driving the vacuum suction cup to fall. Since the packaging bag side facing the transfer mechanism 3 is relatively flat, it is convenient for the transfer mechanism 3 to transfer the packaging bag on the vacuum suction cup.

[0040] refer to Figure 1 and Figure 2 The top of the support plate 13 is provided with a pressing assembly 136 for pressing the packaging bag. The pressing assembly 136 includes a pressing plate 1361, a pressing drive 1362 for driving the pressing plate 1361 to rise and fall, and a support frame 1363 for supporting the pressing drive 1362. The pressing plate 1361 is provided with a sensor 1364 for detecting the distance between the bottom surface of the pressing plate 1361 and the top surface of the stacked packaging bag. In this embodiment, the pressing drive 1362 is a drive cylinder, and the piston rod of the drive cylinder is connected to the pressing plate 1361. The sensor 1364 is a distance sensor of the prior art. When a gap is detected between the bottom surface of the pressing plate 1361 and the top surface of the packaging bag, the pressing drive 1362 will drive the pressing plate 1361 to fall and press the packaging bag, reducing the probability that the suction assembly 12 will lift the packaging bag and fail to suction when there are few packaging bags.

[0041] refer to Figure 2 A limiting member 131 is slidably mounted on the support plate 13. The limiting member 131 includes a sliding part 132 and a limiting part 133 connected to the sliding part 132. The limiting part 133 abuts against one end of the packaging bag, which can improve the stability of the packaging bags stacking. A locking groove 134 is provided on the sliding part 132, and a locking member 135 is provided on the support plate 13. In this embodiment, the locking member 135 is a bolt and nut. The limiting member 131 achieves sliding installation and locking engagement through the locking groove 134 on the sliding part 132 and the locking member 135 on the support plate 13, which can flexibly adjust the position to adapt to the stacking of packaging bags of different sizes. In addition, the top of the storage bag box 14 has an inclined surface 142 that slopes downward toward the limiting member 131, which facilitates the operator to add packaging bags.

[0042] refer to Figure 1 and Figure 3The transfer mechanism 3 includes a transfer frame 31, a first drive assembly 32 mounted on the transfer frame 31, and a robotic arm 33 connected to the first drive assembly 32. The first drive assembly 32 includes a drive motor 321 mounted on the transfer frame 31, a swing arm 322, and a connecting rod 323. One end of the swing arm 322 is connected to the output shaft of the drive motor 321, and the other end is hinged to the robotic arm 33. Both ends of the connecting rod 323 are hinged to the robotic arm 33 and the transfer frame 31, respectively. The end of the swing arm 322 near the drive motor 321 has a fastening groove 3221 with a threaded hole on its inner wall, and a first bolt 3222 is installed in the threaded hole, facilitating the installation and maintenance of the swing arm 322. The first drive assembly 32 enables the robotic arm 33 to move precisely and stably back and forth between the separation mechanism 1 and the transport mechanism 2. The robotic arm 33 is equipped with a first gripper 331, a second gripper 332, and a first gripping drive 333 that drives the first gripper 331 to rotate. The first gripper 331 and the second gripper 332 are arranged correspondingly, so that the robotic arm 33 can stably grip the packaging bag.

[0043] refer to Figure 4 and Figure 5 The transport mechanism 2 includes a transport disk 21, a third drive component 22 for driving the transport disk 21 to rotate, and several transport clamping assemblies 23 evenly spaced and circumferentially mounted on the transport disk 21. The transport clamping assembly 23 includes two sets of transport rods 231 disposed on the transport disk 21, transport clamping claws 232 rotatably mounted on the ends of the transport rods 231, and a transport drive assembly 233 for driving the transport clamping claws 232 to rotate and open. A torsion spring for resetting is provided on the rotation shaft of the transport clamping claws 232. The bottom of the transport rod 231 is provided with a first sliding groove 2311. The transport drive assembly 233 includes a push rod 2331 slidably mounted in the first sliding groove 2311 of the transport rod 231, a reset spring 2332 connecting the push rod 2331, and the transport drive component 2333. A push post 2334 is provided at the bottom of the push rod 2331. The transport gripper 232 is provided with an anti-slip pad 2321, and the anti-slip pad 2321 is fixed to the part of the transport gripper 232 away from the transport rod 231 by a second bolt 2322.

[0044] refer to Figure 1 and Figure 4The transport drive component 2333 is located at the bottom of the transport tray 21, and a limit frame 24 is provided at the output end of the transport drive component 2333. The push column 2334 abuts against the inner wall of the limit frame 24 away from the transfer mechanism 3. The transport drive component 2333 drives the limit frame 24 to move closer to the transfer mechanism 3, which in turn drives the push column 2334 to move closer to the transfer mechanism 3, so that the transport gripper 232 can rotate and open to receive the packaging bag from the transfer mechanism 3; then the transport drive component 2333 drives the limit frame 24 to move away from the transfer mechanism 3, and the push column 2334 resets, so that the transport gripper 232 closes, thereby stably gripping the packaging bag from the transfer mechanism 3.

[0045] The implementation principle of the packaging bag separation and transfer device in this application embodiment is as follows: After the operator places the packaging bag in the storage box 14 of the separation mechanism 1, the lifting drive component 11 drives the suction component 12 to rise and suck up a single packaging bag. Then, the lifting drive component 11 drives the suction component 12 to fall. At this time, the first drive component 32 in the transfer mechanism 3 drives the robot arm 33 to move towards the separation mechanism 1. Then, the robot arm 33 clamps the single packaging bag on the suction component 12. Finally, the first drive component 32 in the transfer mechanism 3 drives the robot arm 33 to move towards the transfer mechanism 3. The carrier mechanism 2 can receive and clamp the single packaging bag on the robot arm 33, thereby realizing the integrated operation of packaging bag separation and transfer, improving the accuracy of separating stacked packaging bags and the efficiency of transfer.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
