Description

Technical Field

[0001] This utility model relates to the field of mask production technology, specifically to an anti-collision feeding device for packaging boxes. Background Technology

[0002] During the mask production process, the masks processed on the production line are inspected and qualified before being packed into mask packaging boxes. The boxes full of masks are then neatly arranged in a matrix and placed in turnover boxes for storage and turnover.

[0003] When the turnover box is transferred to the packaging box wrapping heat shrink film process, the robot takes out the packaging box (product) from the turnover box and places it on the packaging box conveyor line. The conveyor belt of the line transports the packaging box to the heat shrink film packaging equipment for wrapping the packaging box with heat shrink film.

[0004] To improve the loading speed of packaging boxes, robotic arms are evenly distributed on both the front and back sides of the production line. The robotic arms on both sides grab the packaging boxes in the turnover boxes on both sides and then place them on the front and back unloading stations of the same packaging box conveyor line.

[0005] The inventors of this application discovered that, since the packaging boxes gripped by the two robotic arms are placed at two unloading stations on the same conveyor line, when the rear robotic arm unloads the packaging boxes, it needs to avoid the packaging boxes unloaded by the front robotic arm, which reduces the working efficiency of the rear robotic arm and affects the overall efficiency of the equipment.

[0008] The conveyor line is fixedly installed and used to transport packaging boxes;

[0009] The first robotic arm and the second robotic arm are mounted on the machine platform and are located on opposite sides of the conveyor line, respectively.

The supporting side plate is provided with a second feeding station, which is located at the rear end of the first feeding station in the length direction of the conveyor line, and is used for the second robot to place packaging boxes.

[0012] The pushing mechanism is mounted on the support side plate and is used to push the packaging box on the second feeding station onto the conveyor line;

The packaging box picked up by the second robotic arm is placed at the second feeding station on the support side plate. When the photoelectric sensor detects that there is no packaging box on the conveyor belt in front of the second feeding station, the pushing mechanism activates, pushing the packaging box at the second feeding station onto the conveyor belt, ensuring that the packaging box will not collide with the packaging box placed by the first robotic arm on the conveyor belt. At the same time, both robotic arms can freely feed and unload materials, improving the overall efficiency of the equipment.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0037] As described in the background section of this application, robotic arms are installed on both the front and rear sides of the packaging box conveyor line. The robotic arms on both sides grab the packaging boxes from the turnover boxes on both sides and place them on the front and rear unloading stations of the same packaging box conveyor line. The conveyor line then transports the packaging boxes to the next station.

[0038] The inventors of this application discovered that, since the packaging boxes picked up by the two robotic arms are placed at two unloading stations on the same conveyor line, in order to prevent the packaging boxes placed by the two robotic arms from colliding, the rear robotic arm must avoid the packaging boxes placed by the front robotic arm when unloading, which reduces the working efficiency of the rear robotic arm and affects the overall efficiency of the equipment.

[0039] To address the aforementioned problems, the inventors of this application have proposed a technical solution, the specific embodiments of which are as follows:

[0040] Figure 1 This is a top view schematic diagram of the anti-collision feeding device for packaging boxes in an embodiment of this utility model. Figure 2 As described in the embodiments of this utility model Figure 1 A magnified view of a portion of the image. Figure 3 This is a front view schematic diagram of the anti-collision feeding device in an embodiment of this utility model. Figure 4 This is a three-dimensional schematic diagram of the anti-collision feeding device in an embodiment of this utility model. Figure 5 As described in the embodiments of this utility model Figure 4 A magnified view of a portion of the image. Figure 6 This is a schematic diagram of the feeding mechanism in an embodiment of the present utility model.

[0041] like Figures 1 to 6 As shown, the anti-collision feeding device for packaging boxes in this embodiment includes: a machine base 1, a conveyor line 2, a first robotic arm 31, a second robotic arm 32, a support side plate 4, a pushing mechanism 5, a photoelectric sensor 6, and a controller.

[0042] The machine base 1 and the conveyor line 2 are fixedly installed, and the conveyor line 2 passes above the machine base 1. The conveyor belt 22 of the conveyor line 2 is used to transport the packaging box 100 to the next process station for wrapping heat shrink film.

[0043] The first robotic arm 31 and the second robotic arm 32 are mounted on the machine base 1, and the first robotic arm 31 and the second robotic arm 32 are located on the front and rear sides of the conveyor line 2, respectively.

[0044] The first unloading station 201 is provided at the head end of the conveyor line 2. The packaging box grasped by the first robot arm 31 is placed at the first unloading station 201 of the conveyor line 2, and then conveyed to the next process by the conveyor line 2.

[0045] The support side plate 4 is mounted on the frame 21 of the conveyor line 2. The top surface of the support side plate 4 is basically flush with the top surface of the conveyor belt 22 of the conveyor line 2, and the support side plate 4 and the second robot arm 32 are located on the same side (front side) of the conveyor line 2. The support side plate 4 is provided with a second feeding station 401. The second feeding station 401 and the first feeding station 201 are spaced a certain distance apart along the length of the conveyor line 2, and the second feeding station 401 is located at the rear end of the first feeding station 201. The packaging box grasped by the second robot arm 32 is placed on the second feeding station 401 of the support side plate 4. Therefore, the second robot arm 32 will not be affected by the packaging box placed on the conveyor belt 22 by the first robot arm 31 when feeding.

[0046] The pushing mechanism 5 is installed on the support side plate 4. The pushing mechanism 5 is used to push the packaging box placed on the second feeding station 401 of the support side plate 4 onto the conveyor belt 22 of the conveyor line 2, and then the conveyor belt 22 transports the packaging box 100 to the next process heat shrink film coating station.

[0047] The photoelectric sensor 6 is installed on the frame 21 of the conveyor line 2, located between the first feeding station 201 and the second feeding station 401, that is, the photoelectric sensor 6 is installed at the front end of the second feeding station 401.

[0048] The conveyor line 2, the first robotic arm 31, the second robotic arm 32, the pushing mechanism 5, and the photoelectric sensor 6 are electrically connected to the controller. The controller controls each component to perform corresponding preset actions according to the preset program.

[0049] In this embodiment, controlled by a controller, the first robotic arm picks up a package and places it at the first unloading station of the conveyor line. The conveyor belt then transports the package to the next process. The second robotic arm picks up a package and places it at the second unloading station on the support side plate, then turns back to continue picking up packages. The second robotic arm is not affected by the packages on the conveyor belt when unloading. When the photoelectric sensor detects that there are no packages on the conveyor belt in front of the second unloading station, the pushing mechanism activates, pushing the package on the second unloading station onto the conveyor belt. This ensures that the package does not collide with the package placed by the first robotic arm on the conveyor belt, and allows both robotic arms to freely pick up and unload packages, improving the overall efficiency of the equipment.

[0050] As can be seen from the above, the anti-collision feeding device for packaging boxes in this embodiment comprises a machine base, a conveyor line, a first robotic arm, a second robotic arm, a supporting side plate, a pushing mechanism, a photoelectric sensor, and a controller. The first and second robotic arms are mounted on the machine base, located on opposite sides of the conveyor line. A first unloading station is located at the beginning of the conveyor line. The supporting side plate is mounted on the frame of the conveyor line, and a second unloading station is located on the supporting side plate, situated behind the first unloading station along the length of the conveyor line. The pushing mechanism is mounted on the supporting side plate, and the photoelectric sensor is mounted on the conveyor line, located between the first and second unloading stations. This anti-collision feeding device for packaging boxes is controlled by the controller. The packaging box grasped by the first robotic arm is placed at the first unloading station of the conveyor line, and the conveyor belt transports the packaging box to the next process. The packaging box picked up by the second robotic arm is placed at the second feeding station on the support side plate. When the photoelectric sensor detects that there is no packaging box on the conveyor belt in front of the second feeding station, the pushing mechanism activates, pushing the packaging box at the second feeding station onto the conveyor belt, ensuring that the packaging box will not collide with the packaging box placed by the first robotic arm on the conveyor belt. At the same time, both robotic arms can freely feed and unload materials, improving the overall efficiency of the equipment.

[0051] Optionally, the anti-collision feeding device for packaging boxes in this embodiment includes a pushing mechanism 5 comprising a pushing cylinder 51 and a pushing plate 52.

[0052] The pusher cylinder 51 is mounted on the support side plate 4 and is electrically connected to the controller.

[0053] The pusher plate 52 is connected to the telescopic rod of the pusher cylinder 51. The telescopic rod of the pusher cylinder 51 drives the pusher plate 52 to extend and retract. When the pusher plate 52 extends, it pushes the packaging box 100 placed on the second feeding station 401 onto the conveyor belt 22 of the conveyor line 2.

[0054] Furthermore, the anti-collision feeding device for packaging boxes in this embodiment, the pushing mechanism 5, also includes: a translation cylinder 53.

[0055] The translation cylinder 53 is mounted on the support side plate 4, located on the side away from the second unloading station 401 (second robot).

[0056] The pusher cylinder 51 is connected to the telescopic rod of the translation cylinder 53. The translation cylinder 53 is used to drive the pusher cylinder 51 to move left and right on the support side plate 4, so that the pusher cylinder 51 moves closer to and / or further away from the second feeding station 401 of the support side plate 4.

[0057] In this embodiment, the pushing mechanism is also equipped with a translation cylinder. When the second robot arm moves to the second unloading station on the support side plate to unload material, the translation cylinder drives the pushing cylinder to move to the right side of the support side plate away from the second unloading station. After the second robot arm unloads the material, the translation cylinder drives the pushing cylinder to move to the left side of the support side plate, corresponding to the position of the second unloading station. Then, the pushing cylinder pushes the packaging box on the second unloading station onto the conveyor line. By moving the pushing cylinder left and right with the translation cylinder, it makes way for the second robot arm to unload material. When the second robot arm unloads material, the translation cylinder drives the pushing cylinder away from the second unloading station, thereby reducing the installation height of the second robot arm.

[0058] Optionally, in this embodiment, the anti-collision feeding device for packaging boxes has a sliding plate 7 between the second feeding station 401 of the supporting side plate 4 and the conveyor belt 22 of the conveyor line 2.

[0059] The slide plate 7 is set on the frame 21 of the conveyor line 2. When the pusher cylinder 51 drives the pusher plate 52 to push the packaging box 100, the packaging box 100 moves onto the conveyor belt 22 via the slide plate 7, making the movement of the packaging box smoother.

[0060] Optionally, in this embodiment, the anti-collision feeding device for packaging boxes is provided with a limiting plate 8 on the frame 21 of the conveyor line 2.

[0061] Limiting plates 8 are set on both sides of the conveyor belt 22 to form a limiting channel on the conveyor line 2 for the packaging box to pass through, preventing the packaging box from shifting during transportation.

[0062] Optionally, in this embodiment, the anti-collision feeding device for packaging boxes is equipped with a vacuum suction cup 301 for both the first robotic arm 31 and the second robotic arm 32. The first robotic arm 31 and the second robotic arm 32 use the vacuum suction cup 301 to pick up and grab the packaging box 100.

[0063] Furthermore, in this embodiment, the anti-collision feeding device for packaging boxes has a camera 302 installed at the vacuum suction cup 301 for both the first robotic arm 31 and the second robotic arm 32.

[0064] The camera 302 captures positional images and sends them to the controller. The controller then controls the movement of the robotic arm based on the image information, making the robotic arm's gripping and releasing of materials more precise.

[0065] In this utility model, unless otherwise explicitly specified and limited, the first feature being "on" or "below" the second feature can mean that the first feature and the second feature are in direct contact, or that the first feature and the second feature are in indirect contact through an intermediate medium.

[0066] Furthermore, "above," "on top of," and "above" the first feature in relation to the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "under," and "beneath" the first feature in relation to the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
