Description

Technical Field

[0001] This utility model relates to the field of blister packaging technology, and in particular to a rapid stacking rack for plastic packaging after blister forming. Background Technology

[0002] In the plastic packaging production process, the blister boxes after blister forming need to be stacked and sorted for subsequent storage, transportation and further processing. At present, most of the equipment used for stacking blister boxes in the industry is the traditional fixed stacking rack, which is usually composed of a fixed support and a support plate. The blister boxes are stacked one by one by manual or robotic arms on the support plate. However, these traditional stacking racks have obvious limitations. Their fixed overall structure limits the number of blister boxes a single rack can hold. When the blister boxes on the support plate are stacked to a certain height, in order to avoid tipping or deformation due to excessive stacking, workers need to temporarily transfer the stacked blister boxes to the storage area or transport vehicle before starting a new stacking process. During this process, workers need to frequently travel between the stacking rack and the storage area, which not only increases the intensity of manual labor but also seriously affects the continuity of production, resulting in low overall production efficiency.

[0003] Therefore, it is necessary to provide a new rapid stacking rack for plastic packaging after thermoforming to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a quick stacking rack for plastic packaging after thermoforming.

[0005] The quick stacking rack for plastic packaging after blister forming provided by this utility model includes: a support, an L-shaped flipping rack, a rotating component, a mounting block, and a snap-fit ​​component. The support has stacking plates for stacking blister boxes at equal intervals inside. Each side of the stacking plate is provided with an L-shaped flipping rack for removing the stacked blister boxes. A rotating component is installed between the support and the stacking plates. The rotating component drives the stacking plates to rotate to collect the blister boxes. Each side of the L-shaped flipping rack is provided with a mounting block. A snap-fit ​​component is installed between the L-shaped flipping rack and the mounting block. The snap-fit ​​component is used to quickly unlock the restriction on the L-shaped flipping rack.

[0006] Preferably, the rotating assembly includes a motor and a rotating disk. The motor is mounted at the bottom of the bracket, and the output end of the motor is fixedly connected to the rotating disk. The stacking plates and mounting blocks are all fixedly connected to the top of the rotating disk, and the L-shaped flipping frames are all rotatably connected to the top of the rotating disk.

[0007] Preferably, the bottom of the rotating disk is fixedly connected with limit blocks at equal intervals, and the angle between each pair of adjacent limit blocks is 90 degrees. The bottom of the bracket is fixedly connected with a cylinder, and the output end of the cylinder is fixedly connected with a locking block.

[0008] Preferably, the snap-fit ​​assembly includes: a pressing block, a protruding rod, and a spring. The bottom end of the L-shaped flip frame is fixedly connected to a pressing block corresponding to the mounting block. Both sides of the pressing block are provided with snap-fit ​​grooves. The inner wall of the mounting block is fixedly connected to a spring. The other end of the spring is fixedly connected to a protruding rod. The protruding rod is slidably connected to the inner wall of the corresponding mounting block. The end of the protruding rod away from the spring is spherical and snaps into the corresponding snap-fit ​​groove.

[0009] Preferably, a sleeve is fixedly connected to the top of the bracket, a tension spring is fixedly connected to the inner wall of the sleeve, a slide rod is fixedly connected to the other end of the tension spring, a support plate is fixedly connected to the bottom end of the slide rod, and the support plate is located inside the stacked plate. A displacement sensor is fixedly connected to the top of the end of the support plate near the slide rod.

[0010] Preferably, an arc-shaped connecting plate is fixedly connected to the bottom of every two adjacent stacked plates.

[0011] Compared with related technologies, the rapid stacking rack for plastic packaging after thermoforming provided by this utility model has the following advantages: By equidistantly arranging multiple stacking plates inside the support frame and using a rotating component to drive the stacking plates to rotate and switch workstations, continuous stacking of multiple sets of blister boxes is achieved. Compared with the limited capacity of a single traditional fixed stacking rack, this significantly reduces the number of times workers need to frequently move blister boxes, solves the production interruption problem caused by frequent moving of traditional equipment, and effectively ensures the continuity of production. The rotating component is driven by a motor and works in conjunction with a cylinder, a locking block, and a limit block to achieve precise positioning and fixation of the rotating disk, enabling the switching of stacking plates without manual intervention. The displacement sensor on the pallet can detect the stacking height of the blister boxes in real time, and automatically trigger the rotation mechanism when it reaches saturation. This automated switching of workstations and stacking monitoring reduces manual operation, avoids delays and errors caused by human operation, and greatly improves the overall efficiency of blister box stacking. Under the action of the tension spring, the tray can always maintain contact with the blister box, providing stable support for the stacked blister boxes and preventing them from tipping over or shifting during the stacking process; when the turntable rotates, the stacking plate can effectively shield the stacked blister boxes, preventing them from falling off during workstation switching; the arc-shaped connecting plate provides support when the tray is detached from the blister box, ensuring the stability of the tray when it is reset. In the snap-fit ​​assembly, the ball-shaped design of the protruding rod and the elastic cooperation of the spring make the unlocking and resetting operation of the L-shaped flip frame simple and efficient. Workers can quickly remove the blister box and reset the stacking rack without the need for tools. Attached Figure Description

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0016] Please see Figures 1 to 7A rapid stacking rack for blister-formed plastic packaging is disclosed. The rack comprises: a support 1, an L-shaped flipping frame 3, a rotating assembly, mounting blocks 4, and a snap-fit ​​assembly. The support 1 has stacking plates 2 evenly spaced inside for stacking blister boxes. Each side of the stacking plates 2 has an L-shaped flipping frame 3 for removing stacked blister boxes. A rotating assembly is installed between the support 1 and the stacking plates 2, driving the stacking plates 2 to rotate and collect the blister boxes. Each side of the L-shaped flipping frame 3 has a mounting block 4, and a snap-fit ​​assembly is installed between the L-shaped flipping frame 3 and the mounting blocks 4. The component includes a snap-fit ​​assembly for quickly unlocking the restriction on the L-shaped flip frame 3, and a rotating assembly including a motor 5 and a rotating disk 6. The motor 5 is mounted on the bottom of the bracket 1, and the output end of the motor 5 is fixedly connected to the rotating disk 6. Several stacking plates 2 and mounting blocks 4 are fixedly connected to the top of the rotating disk 6, and several L-shaped flip frames 3 are rotatably connected to the top of the rotating disk 6. Limiting blocks 7 are fixedly connected at equal intervals at the bottom of the rotating disk 6, and the angle between each two adjacent limiting blocks 7 is 90 degrees. A cylinder 8 is fixedly connected to the bottom of the bracket 1, and a locking block 9 is fixedly connected to the output end of the cylinder 8.

[0017] It should be noted that both motor 5 and cylinder 8 are existing, mature equipment.

[0018] Please see Figure 4 and Figure 5 The snap-fit ​​assembly includes: a pressing block 10, a protruding rod 11, and a spring 12. The bottom end of the L-shaped flip frame 3 is fixedly connected to a pressing block 10 corresponding to the mounting block 4. The pressing block 10 has a slot on both sides. The inner wall of the mounting block 4 is fixedly connected to a spring 12. The other end of the spring 12 is fixedly connected to a protruding rod 11. The protruding rod 11 is slidably connected to the inner wall of the corresponding mounting block 4. The end of the protruding rod 11 away from the spring 12 is spherical and snaps into the corresponding slot. The top of the bracket 1 is fixedly connected to a sleeve 13. The inner wall of the sleeve 13 is fixedly connected to a tension spring 14. The other end of the tension spring 14 is fixedly connected to a sliding rod 15. The bottom end of the sliding rod 15 is fixedly connected to a support plate 16, and the support plate 16 is located inside the stacking plate 2. The top of the end of the support plate 16 near the sliding rod 15 is fixedly connected to a displacement sensor 17. The bottom ends of every two adjacent stacking plates 2 are fixedly connected to an arc-shaped connecting plate 18. It should be noted that: when the worker holds the L-shaped flip frame 3 and pulls it outward, the squeezing block 10 gradually disengages from the mounting block 4 through the lever principle; during this process, the slots on both sides of the squeezing block 10 will squeeze the spherical end of the protrusion 11 inside the mounting block 4, forcing the protrusion 11 to slide into the mounting block 4 and compress the spring 12 until the squeezing block 10 is completely disengaged from the protrusion 11, and the L-shaped flip frame 3 is opened; at this time, the worker can easily take out the stacked blister boxes, and then reset the L-shaped flip frame 3. Under the elastic force of the spring 12, the protrusion 11 is re-engaged into the slot of the squeezing block 10, completing the fixation of the L-shaped flip frame 3.

[0019] The working principle of the rapid stacking rack for plastic packaging after blister forming provided by this utility model is as follows: In the initial state, the tray 16 is located in the upper middle position inside the stacking plate 2, ready to receive blister boxes; the locking block 9 at the bottom of the rotating disk 6 is tightly engaged with the limiting block 7, and the rotating disk 6 is fixed by the action of the cylinder 8 to prevent it from rotating accidentally during the stacking process and to ensure the accuracy of the stacking position; at this time, all stacking plates 2 are in the state of waiting to collect blister boxes, and the L-shaped flipping frame 3 is connected to the mounting block 4 through the locking component, and is in the state of limiting the blister boxes; After being processed and shaped, the blister box is picked up by the robotic arm and placed above the stacking plate 2. Then the robotic arm releases, and the blister box falls smoothly onto the tray 16. As the blister boxes are continuously stacked, the pressure on the tray 16 gradually increases. Under the action of pressure, the tray 16 drives the slide rod 15 to move downward along the sleeve 13 axis, while stretching the tension spring 14. The displacement sensor 17 fixed at the end of the tray 16 detects the displacement of the tray 16 in real time, thereby monitoring the stacking height of the blister boxes. When the tray 16 moves under pressure to below the arc-shaped connecting plate 18 at the bottom of the stacking plate 2, it indicates that the blister pack inside the stacking plate 2 has reached saturation. At this time, the displacement sensor 17 transmits a signal to the control system, and the rotating assembly is ready to start. First, the cylinder 8 receives the signal and moves, causing the locking block 9 to disengage from the inside of the limiting block 7, releasing the restriction on the rotating assembly and creating conditions for the rotation of the rotating disk 6. After cylinder 8 is released from its restraint, motor 5 starts, and its output drives the fixedly connected rotating disk 6 to rotate 90 degrees. During the rotation, the stacked plates 2 that have been stacked move with the rotating disk 6, and the structure of the stacked plates 2 will block the stacked blister boxes to prevent them from falling. At the same time, after the tray 16 is separated from the blister box, it contacts the arc-shaped connecting plate 18 and remains stable under the support of the arc-shaped connecting plate 18. When the rotating disk 6 rotates to its position, the adjacent stacked plates 2 rotate to the unloading area to prepare to receive new blister boxes. After the adjacent stacking plate 2 moves to the position corresponding to the tray 16, the tension spring 14 releases the previously stored tension, driving the slide bar 15 and the tray 16 to move upward until the tray 16 returns to the upper middle area inside the stacking plate 2, waiting to collect new blister boxes; at the same time, the cylinder 8 starts again, and its output end drives the locking block 9 to extend and engage with the corresponding limiting block 7, re-fixing the rotating disk 6 to prevent the rotating disk 6 from shaking during subsequent stacking and causing the stack to shift; the robotic arm starts again, grabs the blister box and places it on the new stacking plate 2, starting a new round of stacking operations; When the last stacking plate 2 begins to collect blister boxes, the worker can perform a material removal operation on the stacking plate 2 that has collected the blister boxes. Specifically, the worker holds the L-shaped flipping frame 3 and pulls it outward, using the lever principle to gradually detach the extrusion block 10 from the mounting block 4. During this process, the slots on both sides of the extrusion block 10 will press the spherical end of the protrusion rod 11 inside the mounting block 4, forcing the protrusion rod 11 to slide into the mounting block 4 and compress the spring 12 until the extrusion block 10 is completely disengaged from the protrusion rod 11, and the L-shaped flipping frame 3 is opened. At this time, the worker can easily take out the stacked blister boxes, and then reset the L-shaped flipping frame 3. Under the elastic force of the spring 12, the protrusion rod 11 is re-engaged into the slot of the extrusion block 10, completing the fixation of the L-shaped flipping frame 3, waiting for the next material removal.
