Description

Technical Field

[0001] This utility model relates to the field of packaging bag handling technology, specifically to a bag material gripper. Background Technology

[0002] The mixing ratio of calcium oxalate and EDTA and other materials requires picking up materials from the transfer pallet and placing them on top of the mixing hopper to open the bags; traditional handling is all manual, with harsh working environment, high labor intensity, high risk of accidents, and low work efficiency.

[0003] Currently, the main method for handling bagged calcium oxalate raw materials is to use grippers to hold and transfer the material. While this method allows for convenient handling of bagged calcium oxalate, it also presents challenges such as bag scraping and bags failing to detach during the handling process. Furthermore, it can easily result in the handling of multiple bags, making it difficult to efficiently handle and transfer bagged calcium oxalate. Utility Model Content

[0023] 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.

[0024] like Figures 1-4 As shown, a bag-filling material gripper in this embodiment includes a support plate 1. Two cylinders 2 are symmetrically mounted on both sides of the bottom end of the support plate 1, with the two cylinders 2 facing opposite directions. The telescopic part of each cylinder 2 is connected to a rotating shaft 4. A rotating shaft mounting plate 14 is mounted on both ends of the rotating shaft 4 at the bottom end of the support plate 1. A gripper 5 is mounted on the bottom end of the rotating shaft 4. A baffle 9 is provided at the lower middle part of the support plate 1. A photoelectric switch 13 is mounted on the top center of the baffle 9. A solenoid valve 3 is mounted on one side of the top of the support plate 1. Four guide shafts 7 are mounted on the top center of the support plate 1. A floating spring 6 is mounted on the outer side of each guide shaft 7. A mounting flange 10 is mounted on the top of the four guide shafts 7. A limit switch 12 is mounted on one side of the bottom end of the mounting flange 10. The control 12 can control the downward pressing distance of the gripper 5. A linear bearing 8 is installed at the bottom of each guide shaft 7. When gripping and transferring bagged calcium oxalate raw materials, the gripper is first installed on the front robotic arm of the robot with the installation flange 10. Under the control of the robot, it moves to the top of the bagged material tray. The two rows of grippers 5 on the gripper are inserted into the bag. The cylinder 2 pushes the rotating shaft 4 to rotate, thereby hooking the bag with the grippers 5. The robot then picks up the bag and transports it to the powder mixing hopper. The cylinder 2 retracts the telescopic shaft, pushing the grippers 5 back to the vertical position. The bag falls to the mixing hopper under the action of gravity for bag breaking and mixing. The robot returns to the top of the tray to carry out the next round of bag gripping and transportation.

[0025] like Figures 1-4 As shown in this embodiment, a reinforcing support frame 11 is also installed between the two rotating shaft mounting plates 14 located on the same side at the bottom end of the support plate 1. The reinforcing support frame 11 is an angle plate structure. The reinforcing support plate 1 is bolted to the support plate 1 and the rotating shaft mounting plate 14. The reinforcing support frame 11 improves the structural strength between the rotating shaft mounting plate 14 and the support plate 1.

[0026] like Figures 1-4As shown, in this embodiment, the fixed part of the cylinder 2 is bolted to the support plate 1, and the telescopic part of the cylinder 2 is rotatably engaged with the rotating shaft 4. When the telescopic part of the cylinder 2 extends or retracts, it drives the rotating shaft 4 to rotate, so that the direction of the gripper 5 can be changed when the rotating shaft 4 rotates. The rotating shaft 4 is rotatably engaged with the rotating shaft mounting plate 14, and the gripper 5 is bolted to the rotating shaft 4. The gripper 5 has a straight rod structure. The baffle 9 is connected to the support plate 1 by a screw and a nut. The mounting bracket of the photoelectric switch 13 is bolted to the baffle 9. The photoelectric switch 13 is mainly used to detect whether there is a material bag under the gripper 5. The linear bearing 8 is bolted to the support plate 1, and the guide shaft 7 is bolted to the mounting flange 10. The guide shaft 7 passes through the floating spring 6. The top end of the floating spring 6 is inserted into the bottom end of the mounting flange 10, and the bottom end of the floating spring 6 is inserted into the top end of the support plate 1. The support plate 1 is connected to the mounting flange 10 through the guide shaft 7, the floating spring 6, and the linear bearing 8, so that the entire gripper can float and grip the material bag.

[0027] The specific implementation process of this embodiment is as follows: When grabbing and transferring bagged calcium oxalate raw materials, the bagged material gripper is first installed on the front end of the robot's robotic arm using the mounting flange 10. Under the robot's control, it moves to the top of the bagged material tray. The two rows of claws 5 on the bagged material gripper are inserted into the material bag. The cylinder 2 pushes the rotating shaft 4 to rotate, thereby hooking the material bag with the claws 5. The robot then grabs the material bag and transports it to the powder mixing hopper. The cylinder 2 retracts its telescopic shaft, pushing the claws 5 back to the vertical position. The material bag falls onto the mixing hopper under gravity for bag breaking and mixing. The robot returns to the top of the tray to perform the next round of bag grabbing and handling operations. Due to the action of this bagged material grabbing robot, the situation of scraping the bag and the material bag not falling off during the grabbing process is avoided. At the same time, the situation of grabbing multiple bags is avoided, thereby reducing labor and time costs and improving the efficiency of bagged material handling operations.

[0028] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
