Description

Technical Field

[0001] The invention belongs to the technical field of packaging bag stacking, and in particular relates to automatic stacking equipment for large quantities of packaging bags. Background Art

[0002] The devices for stacking packaging bags are generally divided into robot stacking and automatic stacking machines. The working principle of robot stacking is that the qualified packaging bags are sent to the leveling machine via the conveyor to be leveled to make the bag shape flat. After the packaging bags reach the grabbing track, the robot detects and grabs the packaging bags on the track, grabs the packaging bags and turns them, and stacks the packaging bags according to the set stacking shape to complete the stacking procedure.

[0003] CN117049156A is retrieved and disclosed as a large batch automatic stacking device for packaging bags, including a main body, wherein multiple groups of support plates are evenly fixed at the bottom of the main body, and both sides of the multiple groups of support plates are rotatably connected with a transmission shaft. In the present invention, when the bottom of the packaging bag contacts the top of the tray, multiple groups of clamping claw rods and clamping claw plates are separated from the clamping limit of the packaging bag, and when the sliding plate drives the multiple groups of clamping claw rods and the clamping claw plates to extend to the maximum limit, then when the transmission shaft continues to reverse, the flip arm drives the second limit block to rotate along the transmission shaft through the first limit block, and then the clamp arm flips outward at this time, so that the clamp arm is unfolded to complete the stacking operation of the packaging bag. As can be seen from the above, when stacking the packaging bags, the problem of the packaging bags being damaged due to the need to drop the packaging bags in mid-air is effectively avoided, thereby greatly improving the stacking quality of the packaging bags.

[0004] However, the inventors have discovered that this technical solution still has at least the following defects:

[0005] During actual use, the clamp arm rotates around the rotation center, and the motion trajectory of the end of the clamp arm is arc-shaped. After clamping, the end edge of the clamp arm contacts the packaging bag, causing the support point at the bottom of the packaging bag to be a line, which leads to an unbalanced force position, which can easily cause the packaging bag to be unbalanced and fall. In addition, when the packaging bag is moving, the top of the packaging bag is not limited by clamping, and the packaging bag is prone to fall when encountering bumps.

A bucket 2081 is mounted at the end of the plug column 208. The gap between the bucket 2081 and the fence 103 corresponds to the gap between the bucket 2081 and the fence 103. After the equipment moves to the specified position, the operator starts the drive motor 201, and the drive motor 201 drives the cam 202 to rotate, the position of the combination groove 203 on the cam 202 changes, and then drives the horizontal limit fixed block 204 to move outward, and the push plate 205 on the fixed block 204 drives the rocker arm 2061 to rotate, and the rocker arm 2061 drives the rocker rod 207 and the positioning shaft 206 to rotate, and the rocker rod 207 pushes the plug column 208 and the bucket 2081 to move horizontally, and the bucket 2081 and the plug column 208 can shovel the packaging bag onto the plug column 208, thereby ensuring that the force on the bottom of the packaging bag is balanced, making it difficult for the packaging bag to shift, and when the bucket 2081 slides toward the packaging bag, the side wall of the packaging bag is in contact with the railing 103, which serves the purpose of limiting the packaging bag and facilitates the movement of the packaging bag to the plug column 208.

[0044] The lifting and locking unit 300 includes a lifting rod 301, which movably penetrates the support plate 101, a top plate 3011 is installed on the top of the lifting rod 301, and the top plate 3011 corresponds to the cam 202, a flat plate 3012 is installed at the bottom of the lifting rod 301, and a guide plate 3013 is installed on the side wall of the flat plate 3012, and the guide plate 3013 and the plug column 208 are movably plugged; when the cam 202 rotates to the top, the top of the cam 202 contacts the top plate 3011, driving the top plate 3011 and the lifting rod 301 to move upward, The lifting rod 301 pulls the flat plate 3012 and the guide plate 3013 to slide upward, and the pin 208 on the guide plate 3013 slides on the rocker arm 207, which can eventually push the packaging bag on the pin 208 to move upward, and can be squeezed with the top support plate 101, thereby fixing the top of the packaging bag, wherein the four sides of the packaging bag are positioned by the rocker arm 207, the push rod 401, and the railing 103 to ensure that the packaging bag will not deviate and fall, and the upper and lower surfaces of the packaging bag are positioned by the pin 208 and the support plate 101, thereby making the packaging bag clamped more tightly.

[0045] The extrusion guide unit 400 includes a push rod 401, which is movably inserted into the support plate 101. A synchronization rod 402 is installed on the top of the push rod 401. One end of the synchronization rod 402 is slidably connected to a positioning block 4022 opened on the side wall of the cam 202. A slope 4023 is set at one end of the positioning block 4022, and an extrusion spring 3023 is set at the other end of the synchronization rod 402. During the rotation of the cam 202, the positioning block 4022 on the side wall of the cam 202 begins to rotate, and the guiding effect of the slope 4023 can push the synchronization rod 402 at this time to move to the plane of the positioning block 4022, and then the synchronization rod 402 as a whole moves toward the center, and the synchronization rod 402 drives the push rod 401 at the bottom to move toward the center, and the push rod 401 squeezes the packaging bag toward the center, pushing the packaging bag to the center position of the plug column 208, so that the force on the packaging bag is more balanced at this time, making it difficult for the packaging bag to fall, and through the squeezing of the push rod 401, it is ensured that each time the clamping operation is performed, there is no need to control the packaging bag to be located in the center position, because the packaging bag can be corrected and pushed by the later push rod, so that the clamping of the packaging bag is more stable and the clamping speed is faster.

[0046] like Figures 1 to 8 As shown, in a specific embodiment, a mounting plate 102 is mounted on the support plate 101, and a connecting arm 1021 is welded on the mounting plate 102, the connecting arm 1021 is L-shaped, a connecting plate 1022 is mounted at the end of the connecting arm 1021, and a reinforcing rib 1023 is mounted at the end of the connecting arm 1021, and the reinforcing rib 1023 is triangular, and the reinforcing rib 1023 improves the stability of the device. The end of the mechanical arm and the connecting plate 1022 are connected to each other to ensure that the mechanical arm can control the overall movement of the device.

The synchronizing shaft 2021 on the cam 202 can drive the cam 202 on the other side to rotate synchronously, and at this time, the two cams 202 rotate on the mounting seat 2022.

[0048] Embodiment 2:

[0049] The difference between the above embodiment and this embodiment is that: Figures 1 to 8As shown, a guide protrusion 2041 is installed on the fixed block 204, and the guide protrusion 2041 is slidably set in the combined groove 203. A plug rod 2042 is movably inserted on the fixed block 204, and a fixed seat 2044 is installed at the end of the plug rod 2042. The fixed seat 2044 is welded on the support plate 101, and a return spring 2043 is sleeved on the plug rod 2042. One end of the return spring 2043 is clamped on the fixed block 204, and the other end is clamped on the fixed seat 2044. During the rotation of the cam 202, the position of the combination slot 203 on the cam 202 changes, and the position of the plug-in slot 2031 on the combination slot 203 changes. The plug-in slot 2031 can push the horizontally limited fixed block 204 and the guide protrusion 2041 to move horizontally. When the fixed block 204 slides on the plug rod 2042, the fixed block 204 can squeeze the reset spring 2043, and the reset spring 2043 is used to facilitate the subsequent reset operation.

[0050] like Figures 1 to 8 As shown, in a specific embodiment, a connecting block 2052 is installed on the push plate 205, and the connecting block 2052 is connected to the fixed block 204. A strip groove 2051 is provided on the push plate 205, and the strip groove 2051 is in a vertical state. A slide bar 2062 is slidably provided on the strip groove 2051, and the slide bar 2062 is connected to the rocker arm 2061. When the fixed block 204 moves, the push plate 205 connected to the connecting block 2052 starts to move synchronously. At this time, the strip groove 2051 on the push plate 205 moves horizontally, thereby driving the slide bar 2062 on the rocker arm 2061 to slide on the strip groove 2051, and the rocker arm 2061 drives the positioning shaft 206 to rotate on the mounting seat 2022.

[0051] like Figures 1 to 8 As shown, further, an arch bracket 2071 is installed at the bottom of the rocker arm 207, a slide seat 2083 is slidably arranged in the gap of the arch bracket 2071, a connecting rod 2082 is installed on the side wall of the slide seat 2083, a plug column 208 is installed at the end of the connecting rod 2082, a socket 3014 is opened on the guide plate 3013, and the plug column 208 is movably inserted in the socket 3014. After the positioning shaft 206 starts to rotate, the position of the rocker arm 207 on the positioning shaft 206 changes synchronously, and the end of the rocker arm 207 pushes the plug post 208 and the bucket 2081 to move horizontally. At this time, the connecting rod 2082 and the slide seat 2083 on the plug post 208 slide on the arch bracket 2071, which serves the purpose of limiting. When the bucket 2081 and the plug post 208 slide along the socket 3014, the packaging bag can be shoveled onto the plug post 208, thereby ensuring that the force on the bottom of the packaging bag is balanced, making it difficult for the packaging bag to shift.

[0052] Embodiment 3:

[0053] The difference between the above embodiment and this embodiment is that: Figures 1 to 8 As shown, a squeeze rod 3021 is installed on the flat plate 3012, and a squeeze cover 302 is inserted on the outer wall of the squeeze rod 3021, and the squeeze cover 302 is installed at the bottom of the support plate 101. A baffle 3022 is slidably arranged inside the squeeze cover 302, and one end of the baffle 3022 is connected to the squeeze rod 3021, and a squeeze spring 3023 is clamped between the other end of the baffle 3022 and the side wall of the squeeze cover 302, and the compression direction of the squeeze spring 3023 is the same as the moving direction of the squeeze rod 3021. During the sliding process of the flat plate 3012, the squeeze rod 3021 on the flat plate 3012 slides inside the squeeze cover 302, and the baffle 3022 on the squeeze rod 3021 pushes the squeeze spring 3023 to squeeze, and the squeeze spring 3023 facilitates the reset operation later.

[0054] like Figures 1 to 8 As shown, in a specific embodiment, a plurality of pairs of pressure plates 4011 are vertically installed on the side wall of the push rod 401, and the pressure plates 4011 are located on both sides of the bucket 2081. A through hole 1011 is opened on the support plate 101, and the push rod 401 is slidably arranged inside the through hole 1011. A limit seat 4024 is movably inserted at one end of the synchronization rod 402, and the limit seat 4024 is installed on the support plate 101. A guide wheel 4021 is installed at the other end of the synchronization rod 402, and the guide wheel 4021 is slidably arranged on the positioning block 4022. When the cam 202 drives the positioning block 4022 to start rotating, the guiding effect of the ramp 4023 can push the synchronization rod 402 to move to the plane of the positioning block 4022, wherein the guide wheel 4021 can reduce the friction during the movement. When the synchronization rod 402 moves toward the center as a whole, the synchronization rod 402 drives the push rod 401 at the bottom to move toward the center, and the push rod 401 and the pressure plate 4011 squeeze the packaging bag toward the center, pushing the packaging bag to the center position of the plug column 208, so that the force on the packaging bag is more balanced at this time, making the packaging bag less likely to fall, and through the squeezing of the push rod 401 and the pressure plate 4011, it is ensured that each time the clamping operation is performed, there is no need to control the packaging bag to be located in the exact center position, because the packaging bag can be corrected and pushed by the later push rod 401 and the pressure plate 4011, thereby making the clamping of the packaging bag more stable and the clamping speed faster.

[0055] like Figures 1 to 8As shown, further, a positioning cover 403 is sleeved on the synchronization rod 402, and a positioning bracket 4031 is installed on the outer shell of the positioning cover 403. The positioning bracket 4031 is welded and set on the support plate 101. A partition 404 is slidably set inside the positioning cover 403, one end of the partition 404 is connected to the synchronization rod 402, and the other end of the partition 404 is connected to the positioning spring 4041, and the positioning spring 4041 is set in the inner cavity of the positioning cover 403, and the stretching direction of the positioning spring 4041 and the moving direction of the synchronization rod 402 are located on the same straight line. When the synchronization rod 402 slides, the synchronization rod 402 slides along the limit seat 4024, and the partition 404 on the synchronization rod 402 moves toward the positioning spring 4041, which can squeeze and compress the positioning spring 4041, and facilitate the reset operation later through the positioning spring 4041.

[0056] The implementation principle of the automatic stacking equipment for large batches of packaging bags in this embodiment is as follows:

[0057] The end of the robot arm and the connection plate 1022 are connected to each other to ensure that the robot arm can control the movement of the entire device.

[0058] When automatic stacking is required, the operator starts the robot arm, controls the cavity between the bucket 2081 and the fence 103 to correspond to the packaging bag, and starts the equipment to perform the clamping operation.

[0059] Start the driving motor 201, and drive the cam 202 to rotate through the driving motor 201. The synchronous shaft 2021 on the cam 202 can drive the cam 202 on the other side to rotate synchronously. At this time, the two cams 202 rotate on the mounting seat 2022. During the rotation of the cam 202, the position of the combination slot 203 on the cam 202 changes, and the position of the plug-in slot 2031 on the combination slot 203 changes. The plug-in slot 2031 can push the horizontally limited fixed block 204 and the guide protrusion 2041 to move horizontally. When the fixed block 204 slides on the plug rod 2042, the fixed block 204 can squeeze the reset spring 2043, and the reset spring 2043 is used to facilitate the later reset operation. When the guide protrusion 2041 moves to the guide slot 2032, the fixed block 204 stops moving.

[0060] When the fixed block 204 moves, the push plate 205 connected to the connecting block 2052 starts to move synchronously. At this time, the strip groove 2051 on the push plate 205 moves horizontally, thereby driving the slide bar 2062 on the rocker arm 2061 to slide on the strip groove 2051, and the rocker arm 2061 drives the positioning shaft 206 to rotate on the mounting seat 2022.

[0061] After the positioning shaft 206 starts to rotate, the position of the swing rod 207 on the positioning shaft 206 changes synchronously, and the end of the swing rod 207 pushes the plug column 208 and the bucket 2081 to move horizontally, and at this time, the connecting rod 2082 and the slide seat 2083 on the plug column 208 slide on the arch bracket 2071, which plays the purpose of limiting. When the bucket 2081 and the plug column 208 slide along the insertion hole 3014, the packaging bag can be shoveled onto the plug column 208, thereby ensuring that the force on the bottom of the packaging bag is balanced, so that the packaging bag is not easily displaced, and when the bucket 2081 slides toward the packaging bag, the side wall of the packaging bag contacts the fence 103, which plays the purpose of limiting the packaging bag and facilitates the movement of the packaging bag onto the plug column 208. And when the swing rod 207 rotates to the vertical state, the corresponding fixed block 204 slides into the guide groove 2032, and the swing rod 207 will not move afterwards.

[0062] During the above movement, the positioning block 4022 on the side wall of the cam 202 begins to rotate, and the guiding effect of the ramp 4023 can push the synchronization rod 402 at this time to move to the plane of the positioning block 4022, wherein the guide wheel 4021 can reduce the friction during the movement, and when the synchronization rod 402 as a whole moves toward the center, the synchronization rod 402 drives the push rod 401 at the bottom to move toward the center, and the push rod 401 and the pressure plate 4011 squeeze the packaging bag toward the center, pushing the packaging bag to the center position of the plug column 208, so that the force on the packaging bag is more balanced at this time, making the packaging bag less likely to fall, and through the squeezing of the push rod 401 and the pressure plate 4011, it is ensured that each time the clamping operation is performed, there is no need to control the packaging bag to be located in the exact center position, because the packaging bag can be corrected and pushed by the later push rod 401 and the pressure plate 4011, thereby making the clamping of the packaging bag more stable and the clamping speed faster.

[0063] When the synchronization rod 402 slides, the synchronization rod 402 slides along the limit seat 4024, and the partition plate 404 on the synchronization rod 402 moves toward the positioning spring 4041, which can squeeze and compress the positioning spring 4041, and facilitate the subsequent resetting operation through the positioning spring 4041.

[0064] When the fixing block 204 slides on the guide groove 2032 .

[0065] At this time, the far end of the cam 202 contacts the top plate 3011, driving the top plate 3011 and the lifting rod 301 to move upward, and the lifting rod 301 pulls the flat plate 3012 and the guide plate 3013 to slide upward, and the plug column 208 on the guide plate 3013 slides on the rocker bar 207, and finally can push the packaging bag on the plug column 208 to move upward, and can be squeezed with the top support plate 101, so that the top of the packaging bag is fixed, wherein the four sides of the packaging bag are positioned by the rocker bar 207, the push rod 401 and the pressure plate 4011, and the railing 103 to ensure that the packaging bag will not deviate and fall, and the upper and lower surfaces of the packaging bag are positioned by the plug column 208 and the support plate 101, so that the packaging bag is clamped more tightly.

[0066] During the sliding of the flat plate 3012 , the extrusion rod 3021 on the flat plate 3012 slides inside the extrusion cover 302 , and the baffle 3022 on the extrusion rod 3021 pushes the extrusion spring 3023 for extrusion, and the extrusion spring 3023 facilitates the subsequent resetting operation.

[0067] After clamping is completed, the operator can move the packaging bag to the designated stacking position through the robotic arm, and through the reverse process of the above operation, the purpose of unloading can be achieved and the stacking operation can be completed.
