Description

Technical Field

[0001] This utility model relates to a waste paper cleaning structure on a roller die-cutting machine, specifically to a bottle lifting and separating mechanism. Background Technology

[0002] During the packaging process, the bottles must first be arranged in a matrix (e.g., multiple rows and columns), and then a robotic arm will place the bottles into the packaging box. Some packaging boxes have compartments, requiring each row of bottles to be placed into the corresponding compartment after a certain distance has been maintained.

[0003] Existing mechanical grippers lack spacing capabilities and can only be inserted manually by adjusting the spacing row by row, which is inefficient and cannot meet the needs of automated production. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide a mechanism that can automatically arrange medicine bottles in a matrix, divide them at equal intervals, and accurately place them into packaging box compartments, thereby replacing manual operation and improving production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bottle lifting and separating mechanism, comprising: Install support plate; Two parallel guide rods are fixed below the mounting plate; Two or more material-collecting plates are slidably sleeved on the guide rod, wherein the leftmost material-collecting plate is fixedly connected to the mounting support plate; the material-collecting plate is a box with an opening at the bottom, and insert plates are evenly distributed along the contour at the bottom of the box. A receiving groove for inserting bottles is formed between adjacent insert plates. A suction nozzle is provided at the bottom of the receiving groove, and the suction nozzle is connected to the air pump through a first solenoid valve. A limiting plate is provided between adjacent material picking plates. A limiting groove is provided on one side of the limiting plate. The screw of a limiting bolt passes through the limiting groove and is connected to the material picking plate on one side. A fixing screw passes through the limiting plate and is connected to the material picking plate on the other side. The split cylinder is fixed on the mounting plate, and its piston rod is connected to the rightmost material picking plate. The split cylinder is connected to the air pump through the second solenoid valve.

[0006] The material handling plates are multiple and are slidably connected along the direction of the guide rod.

[0007] The insert plate and the material receiving plate are integrally formed on their peripheral walls.

[0008] The length of the limiting groove limits the maximum spacing between adjacent material receiving plates.

[0009] When the piston rod of the split cylinder extends, it pulls the rightmost material-taking plate and, through the limiting plate, links other material-taking plates to form an equidistant interval between each material-taking plate.

[0010] Workflow: The material picking plate moves down to insert the matrix-arranged medicine bottles into the receiving slot, and the suction nozzle adsorbs and fixes them; the piston rod of the spacing cylinder extends and pulls the rightmost material picking plate, which is linked to other material picking plates through the limit plate to form an equidistant interval between each material picking plate; the robot moves the mechanism to the opening of the packaging box, disconnects the air circuit of the first solenoid valve, and the medicine bottles fall into the corresponding compartment to complete the spacing and boxing.

[0011] The beneficial effects of this utility model are: precise equidistant spacing of the material picking plate is achieved through the guide rod and the limiting plate; the suction nozzle ensures the stability of the medicine bottle; automated spacing replaces manual labor, significantly improving packaging efficiency, especially suitable for packaging boxes with compartments.

Detailed Implementation

[0015] The following detailed description of the specific embodiments of the "bottle lifting and spacing mechanism" of this utility model, with reference to the accompanying drawings, is provided to fully disclose the technical solution and support the protection scope of the claims. This embodiment takes a conventionally matrix-arranged medicine bottle (such as a 3×4 arrangement, 12 bottles / row) and a packaging box with compartments as an example, but those skilled in the art can adjust the parameters according to actual production needs.

[0016] like Figure 1 — Figure 3 As shown; I. Overall Structural Composition This bottle lifting and separating mechanism is integrally mounted on the gripping end of a robotic arm (not shown in the diagram, but typically a multi-axis linkage robotic arm). It is used to grip medicine bottles from the bottle matrix arrangement station, separate them, and precisely place them into the corresponding compartments of the packaging box. Its core structure includes a mounting support plate, guide rod, material handling plate, insert plate and receiving slot, suction nozzle system, limit plate assembly, separating cylinder, and matching pneumatic / electrical control system.

[0017] II. Detailed Structure and Connection Relationships of Key Components 1. Install support plate 1 Mounting support plate 1 is a horizontally positioned rectangular metal plate (preferably made of aluminum alloy, which is lightweight and high-strength), serving as the load-bearing base for the entire mechanism. It is fixed to the end effector of the robot arm (not shown in the figure) by bolts at the top, and two guide rods 2 are fixed parallel to each other at the bottom to provide vertical sliding guidance for the material handling plate 3.

[0018] 2. Guide rod 2 Two guide rods 2 are cylindrical optical axes (e.g., 12mm in diameter, with polished surfaces to reduce friction). They are fixed parallel to the bottom of the mounting plate 1 along its length (i.e., the row direction of the matrix arrangement), and both ends are locked to the mounting plate 1 with nuts. The function of the guide rods 2 is to provide vertical guidance for the material picking plates 3, ensuring that each material picking plate 3 maintains positional accuracy during vertical movement and spacing.

[0019] 3. Material Retrieval Section 3 The material handling plates 3 consist of multiple units (four in this embodiment, corresponding to the spacing requirements of four rows of medicine bottles; in practice, there can be 3-8 units, adjusted according to the number of compartments in the packaging box). Each unit is a box structure with an opening at the bottom (dimensions, for example, 150mm long × 50mm wide × 20mm high, made of ABS plastic or aluminum alloy), and is sequentially slidably fitted onto two guide rods 2 along the direction of the guide rods 2. Wherein: The leftmost material handling plate: It is directly fixed to the bottom of the mounting plate 1 by bolts (the fixing position is close to the left edge of the mounting plate 1) as the reference fixing end when spacing. The remaining material handling plates are slidably sleeved on guide rod 2 and can move left and right along guide rod 2 (i.e., adjust their position along the column direction of the matrix arrangement).

[0020] Multiple insert plates 4 are evenly distributed along the outline (i.e., the four edges of the box) below each material receiving plate 3. The insert plates 4 are integrally injection molded with the peripheral wall of the material receiving plate 3 (or fixed by welding / riveting, if made of metal). A "receiving groove 5" is formed between adjacent insert plates 4. The width of the receiving groove 5 is slightly larger than the diameter of the medicine bottle (for example, if the medicine bottle diameter is 20mm, the width of the receiving groove 5 is 22mm), and the depth matches the height of the medicine bottle (for example, if the medicine bottle height is 50mm, the depth of the receiving groove 5 is 55mm), which is used to accommodate a single row of medicine bottles.

[0021] 4. Suction nozzle system Each receiving trough 5 has a suction nozzle (made of silicone or polyurethane to avoid scratching the medicine bottle) at its bottom center. The suction nozzle is connected to the first solenoid valve via an air tube, and the other end of the first solenoid valve is connected to a vacuum pump. When the suction nozzle is powered on (the first solenoid valve is open), the vacuum pump generates negative pressure, causing the suction nozzle to adhere to the bottom of the medicine bottle in the receiving trough 5; when the power is turned off (the first solenoid valve is closed), the negative pressure disappears, and the medicine bottle can detach freely.

[0022] 5. Limiting plate assembly (split positioning structure) A limiting plate 9 is provided between two adjacent material picking plates 3. The limiting plate 9 is a strip metal plate (e.g., 80mm in length and 10mm in width), and a straight limiting groove 10 is provided on one side along the length direction (the groove width matches the screw diameter of the limiting bolt 11, for example, 5mm in width and 30mm in length). The extension direction of the limiting groove 10 is perpendicular to the axis of the guide rod 2 (i.e., the row direction of the matrix arrangement) (i.e., along the column direction of the matrix arrangement).

[0023] The screw of a limiting bolt 11 passes through the limiting groove 10 and is threadedly connected to the material picking plate 3 on the left side of the current limiting plate 9; A fixing screw 12 passes through the other side of the limiting plate 9 and is threadedly connected to the material picking plate 3 on the right side of the current limiting plate 9.

[0024] The maximum spacing between adjacent material picking plates 3 is limited by the length of the limiting groove 10 (for example, if the limiting groove 10 is 30mm long, the adjacent plates can be pulled apart by a maximum distance of 30mm). When the separating cylinder 13 drives the rightmost material picking plate to move, all material picking plates 3 will be separated synchronously and equally through the rigid connection of the limiting plate 9 (for example, the final spacing of the 4 plates is 10mm, and the total unfolded width is adapted to the spacing of the packaging box compartments).

[0025] 6. Pitch cylinder 13 The spacing cylinder 13 is fixed to the mounting plate 1 (located near the right edge of the mounting plate 1), and the end of its piston rod is fixedly connected to the rightmost material-taking plate via a connector. The spacing cylinder 13 is connected to a second solenoid valve via an air pipe, and the other end of the second solenoid valve is connected to an air pump. When the second solenoid valve is open, the air pump supplies air to the spacing cylinder 13, the piston rod extends and pulls the rightmost material-taking plate to the right; when the piston rod retracts (the second solenoid valve switches the air path), it pushes the rightmost material-taking plate to reset to the left.

[0026] III. Work Process (Specific Operational Steps) Step 1: Initial positioning and medicine bottle grasping The robotic arm moves the entire mechanism to the bottle matrix arrangement station (e.g., the end of the conveyor belt after the vibratory feeder has arranged the bottles in the set rows and columns, such as 4 rows × 3 columns). At this time, all the material receiving plates 3 are in a closed state (i.e., there is no gap between adjacent plates, and the receiving grooves 5 between the insert plates 4 are closely arranged).

[0027] The mechanism moves downward (driven by the Z-axis of the robotic arm), aligning each receiving slot 5 with a column of medicine bottles in the matrix. Once the receiving slot 5 completely covers the medicine bottle, the first solenoid valve opens, the vacuum pump starts, and the suction nozzle adheres to and fixes the bottom of the medicine bottle.

[0028] Step 2: Split-out unfolding After the medicine bottle is adsorbed and fixed, the robotic arm drives the mechanism to move upward (disengaging from the matrix arrangement station). Then, the second solenoid valve opens, and the air pump supplies air to the spacing cylinder 13, causing the piston rod to extend. Since the rightmost material-receiving plate is connected to the piston rod, the piston rod pushes the material-receiving plate to move to the right. At the same time, the material-receiving plate pulls the adjacent material-receiving plate on the right side to move synchronously through the limiting plate 9 (fixed screw 12 side) connected to it, and so on, until the leftmost material-receiving plate (fixed to the mounting support plate 1) remains stationary as a reference.

[0029] During this process, the limiting groove 10 of the limiting plate 9 restricts the maximum movement distance of adjacent material picking plates 3, ensuring that the spacing between each plate is uniform (for example, the final spacing of the four plates is Δx, the specific value of which is designed according to the spacing between the packaging box compartments, such as Δx=10mm). At this time, the originally closely arranged medicine bottles are separated at equal intervals, and the center distance of each row of medicine bottles matches the center distance of the packaging box compartments.

[0030] Step 3: Place the medicine bottle into the box After the separation is completed, the robotic arm moves the mechanism above the opening of the packaging box (the packaging box has been pre-positioned, and the compartment positions correspond one-to-one with the positions of the separated medicine bottles). The first solenoid valve closes, the air pump stops working, the suction force of the suction nozzle disappears, and the medicine bottles fall naturally into the corresponding compartments of the packaging box under the action of gravity.

[0031] Step 4: Reset After the medicine bottle is placed into the box, the second solenoid valve switches the air path, and the piston rod of the spacing cylinder 13 retracts, causing the rightmost material-picking plate to move to the left. Through the limit plate 9, the other material-picking plates 3 are reset to their initial closed state (with no gap between adjacent plates). The robotic arm moves the mechanism out of the packaging box area, completing a single spacing and boxing operation, and then enters the next cycle.

[0032] IV. Verification of the Effects of the Examples In this embodiment, the guide rod 2 guides and the limiting plate 9 limits the spacing of the material picking plate 3, ensuring the accuracy of the spacing (error ≤ ±0.5mm). The negative pressure adsorption of the suction nozzle ensures the stability of the medicine bottle during the spacing process (no tipping or falling). Automated spacing replaces the traditional manual row-by-row adjustment, with a single spacing and box insertion time of ≤3 seconds (compared to 10-15 seconds per row manually), significantly improving production efficiency (especially suitable for high-speed packaging lines). In addition, by replacing the limiting plate 9 with different lengths or adjusting the size of the limiting groove 10, it can flexibly adapt to packaging box compartments with different spacing requirements (such as 5mm, 15mm, etc.).
