Description

Technical Field

[0001] The utility model relates to the technical field of heavy bag packaging, in particular to a bag loading manipulator for a heavy bag packaging machine. Background Art

[0002] In the prior art, for example, a Chinese patent (grant number: CN215625175U) discloses an automatic bagging robot for a fully automatic heavy bag packaging machine, comprising a mounting box and a robot body mounted on the upper surface of the mounting box, wherein two bidirectional threaded rods are rotatably mounted in the mounting box, one of the bidirectional threaded rods is mounted with a bevel gear 2, a transmission assembly is arranged on the bidirectional threaded rod, a rotating shaft is rotatably mounted on the inner top surface of the mounting box, and a bevel gear 1 meshing with the bevel gear 2 is mounted on the rotating shaft.

[0003] When in use, a two-way threaded rod and a support plate are set, and the round handle is used to drive the rotating shaft to rotate. The two-way threaded rod is rotated by cooperating with the mutual meshing effect of bevel gear one and bevel gear two, thereby driving the slide to move relative to each other, and the support plate is used to drive the fixed plate to move out of the opening, and the fixed plate is fixed with bolts, thereby increasing the support of the manipulator body, allowing the manipulator to be well used by the user, thereby increasing the scope of application of the manipulator.

[0004] However, the above patent has the following defects when in use: since the entire robot arm is relatively high, if the parts on the robot arm and the gripper are damaged, they need to be repaired, so the staff may not be able to reach them. The method adopted in the prior art is that the staff stands on a stool to perform repairs. At this time, it is impossible for the staff to hold many kinds of tools in their hands. In this way, if the tool needs to be replaced, the staff needs to get down from the stool to get the tool, which is very troublesome and wastes time. Therefore, improvements are needed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a bag loading robot for a heavy bag packaging machine, which solves the problems mentioned in the background technology.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] A bag loading robot for a heavy bag packaging machine comprises an installation box, a robot arm is installed on the top of the installation box, a gripper is installed on the free end of the robot arm, a detachable tool box is installed on the outer shell of the robot arm through a height adjustment device, and a plurality of equally spaced mounting columns are installed on the front and rear sides of the outer shell of the robot arm along its length direction, and the tool box is detachably installed between two of the mounting columns that are opposite to each other front and back.

[0008] Specifically in the utility model, the toolbox includes two symmetrically arranged sub-boxes, which are respectively located at the front and rear sides of the robotic arm. An arc-shaped connecting plate is fixed between the tops of the two sub-boxes away from the inner side of the robotic arm, and a side panel of the sub-box close to the robotic arm can be detachably mounted on a mounting column.

[0009] In order to realize the detachableness of the sub-box on the robot arm, a horizontal long groove is opened on a side panel of the sub-box close to the robot arm, the free end of the mounting column extends into the sub-box through the long groove and is provided with a locking piece, the mounting column is a threaded column, and the locking piece is a nut threadedly installed on the mounting column, and a notch is opened on a side panel of the sub-box away from the arc-shaped connecting plate for the mounting column to pass through, and the notch is connected to the long groove.

[0010] Compared with the prior art, the utility model has the following beneficial effects: a detachable tool box is installed on the mechanical arm, and the tool box can be adjusted in height, so that workers can take tools more conveniently when inspecting the mechanical arm and the gripper, and the structure is simple and the practicability is high.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] like Figure 1As shown, the utility model provides a bag loading robot for a heavy bag packaging machine, including an installation box 1, a robot arm 2 is installed on the top of the installation box 1, and a gripper 3 is installed on the free end of the robot arm 2. The above structures are all prior arts. The specific working principle can be referred to the Chinese patent (grant number: CN215625175U), which will not be repeated in the utility model. A detachable tool box is installed on the outer shell of the robot arm 2 through a height adjustment device, and a plurality of equally spaced mounting columns 4 are installed on the front and rear sides of the outer shell of the robot arm 2 along its length direction, and the tool box is detachably installed between two of the mounting columns 4 that are opposite to each other front and back.

[0018] like Figure 2 , Figure 4 As shown, in the utility model, the toolbox includes two symmetrically arranged sub-boxes 5, the two sub-boxes 5 are respectively located at the front and rear sides of the robotic arm 2, an arc-shaped connecting plate 6 is fixed between the tops of the two sub-boxes 5 away from the inner side of the robotic arm 2, and a side panel of the sub-box 5 close to the robotic arm 2 can be detachably mounted on the mounting column 4.

[0019] like Figure 3 As shown, in order to realize the detachable sub-box body 5 on the robot arm 2, a horizontal long groove 5-1 is opened on a side panel of the sub-box body 5 close to the robot arm 2, the free end of the mounting column 4 extends into the sub-box body 5 through the long groove 5-1, and is provided with a locking piece 7, the mounting column 4 is a threaded column, and the locking piece 7 is a nut threadedly installed on the mounting column 4, and a notch 5-2 for the mounting column 4 to pass through is opened on a side panel of the sub-box body 5 away from the arc-shaped connecting plate 6, and the notch 5-2 is connected to the long groove 5-1.

[0020] The following is a detailed description of the working principle of the distinguishing design of the utility model: when it is necessary to repair parts on the mechanical arm 2, the required tools are loaded into the two sub-boxes 5. According to the height of the repair, the two sub-boxes 5 are slid and inserted into the mechanical arm 2 from the side of the mechanical arm 2 away from the gripper 3. The two mounting posts 4 at the corresponding heights enter the long grooves 5-1 through the notches 5-2. When the tool box reaches a suitable position, according to the height of the repair of the mechanical arm 2, the tool box is rotated so that the tool box rotates around the mounting posts 4 until the tool box tends to be horizontal. The bolts are screwed on the mounting posts 4 until the side of the nut is tightly against the surface of the mechanical arm 2 to lock the tool box. At the same time, the cooperation between the nuts and the mounting posts 4 and the setting of the long grooves 5-1 can enable the tool box to slide horizontally and retract to the side of the mechanical arm 2 away from the gripper 3 to prevent the tool box from hindering the repair of the mechanical arm 2. When the tool box is not in use, the nuts are unscrewed from the mounting posts 4, and the tool box can be slid away from the side of the mechanical arm 2 away from the gripper 3 to achieve disassembly of the tool box.

[0021] Finally, compared with the prior art, the most important contribution of the present invention is that a detachable tool box is installed on the robot arm 2, and the tool box can be adjusted in height, so that workers can take tools more conveniently when inspecting the robot arm 2 and the gripper 3. It has a simple structure and high practicality.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
