Description

Technical Field

[0001] The utility model relates to the technical field of sorting equipment, in particular to a gantry protection net for efficient buffer sorting equipment. Background Art

[0002] Sorting machines are often used in the field of logistics equipment. Common sorting machines mainly transport goods through conveyor belts, which are selected and classified by corresponding scanning equipment and manipulators. During the scanning process, a gantry is required as a support to stand in the middle of the conveyor belt, and the manipulator picks up and scans the goods to achieve accurate scanning. In order to prevent the manipulator from picking up goods incorrectly, a corresponding protective net is usually set at the lower end of the gantry to protect the conveyor belt.

[0003] During the cargo sorting process, a robot is required to grab the cargo and scan it for classification. After the cargo is grabbed by the robot, the cargo falls due to the insufficient grip of the robot, which generates a large impact force and causes a violent collision between the cargo and the protective net belt. Since the protective net belt and the conveyor belt are hard-connected and have poor elasticity, the conveyor belt is easily damaged over a long period of time. To address the above problems, we have launched a gantry protective net for efficient buffer sorting equipment. Utility Model Content

[0007] According to a further technical solution, the upper end of the sleeve away from the spring is connected to a first connecting block, the left and right ends below the mounting plate are connected to second connecting blocks, and a connecting rod is rotatably connected between the first connecting block and the second connecting block.

[0008] By rotating the connecting rod between the first connecting block and the second connecting block, the distance between the mounting plate and the sleeve is changed.

[0009] According to a further technical solution, the front and rear ends of the elastic bending steel plate away from the cylindrical rod are threadedly connected with bolts, the lower end of the elastic bending steel plate is connected to a conveyor belt, and the conveyor belt and the elastic bending steel plate are fixedly connected by bolts.

[0010] The elastic bending steel plate is fixed to the conveyor belt by bolts to ensure that the position of the elastic bending steel plate cannot be shifted.

[0011] According to a further technical solution, second slide grooves are provided at the left and right ends above the conveyor belt, and a gantry body is slidably connected above the second slide grooves.

[0012] The second slide groove is provided to facilitate the movement of the gantry body, and the gantry body moves along the direction of the conveyor belt running track.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] The utility model discloses a high-efficiency buffer sorting equipment gantry protection net which is mainly used in the scene of picking, scanning and sorting goods.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , a gantry guard net of an efficient buffer sorting equipment comprises a guard net body 1, a buffer mechanism 2 is installed below the front and rear ends of the guard net body 1, and the buffer mechanism 2 is used to buffer the impact force of the guard net body 1 from top to bottom; the buffer mechanism 2 comprises a mounting plate 201 fixedly connected to the front and rear ends of the guard net body 1, a first slide groove 202 is provided at the left and right ends below the mounting plate 201, an elastic bending steel plate 203 is slidably connected inside the first slide groove 202, a cylindrical rod 204 is connected to the front and rear ends between the elastic bending steel plates 203, sleeves 205 are slidably connected to the left and right ends of the outer surface of the cylindrical rod 204, springs 206 are connected between the sleeves 205, and a first connecting block 207 is connected to the upper end of the sleeve 205 away from the spring 206, and a second connecting block 208 is connected to the left and right ends below the mounting plate 201, a connecting rod 209 is rotatably connected between the first connecting block 207 and the second connecting block 208, and a conveyor belt 4 is connected to the lower end of the elastic bending steel plate 203;

[0026] In this embodiment, when the goods fall quickly into the upper end of the protective net body 1, the protective net body 1 will generate an impact force from top to bottom, and the impact force is transmitted to the elastic bending steel plate 203 through the mounting plate 201, causing the elastic bending steel plate 203 to be slightly bent under the force, and the upper end of the elastic bending steel plate 203 slides inside the first slide groove 202, and the protective net body 1 moves downward slightly, causing the distance between the protective net body 1 and the conveyor belt 4 to be shortened, and the elastic bending steel plates 203 at the four ends below the protective net body 1 are slightly bent to buffer the impact force brought by the goods, and then the elastic bending steel plates 203 are bent. The steel plate 203 recovers under the action of its own elastic force. While the distance between the protective net body 1 and the conveyor belt 4 is shortened, the second connecting block 208 transmission connecting rod 209 pushes the first connecting block 207 and the two sets of sleeves 205 to move inward on the cylindrical rod 204, causing the spring 206 to contract. By converting the impact force of the falling goods into the squeezing force between the sleeves 205 on the spring 206, the offsetting effect of the impact force is further improved, achieving the buffering effect between the protective net body 1 and the conveyor belt 4, and reducing the damage to the conveyor belt 4 caused by the impact force.

[0027] Reference Figure 1 and Figure 3 In a preferred embodiment, the front and rear ends of the elastic bending steel plate 203 away from the cylindrical rod 204 are threadedly connected with bolts 3, and the conveyor belt 4 is fixedly connected to the elastic bending steel plate 203 by the bolts 3;

[0028] Supplementary explanation: The lower end of the elastic bending steel plate 203 is fixedly connected to the upper end of the conveyor belt 4 by means of bolts 3, so that the position of the lower end of the elastic bending steel plate 203 remains unchanged during the process of counteracting the impact force.

[0029] Reference Figure 1 In a preferred embodiment, a second chute 5 is provided at both ends of the conveyor belt 4, a gantry body 6 is slidably connected above the second chute 5, a scanner 7 is installed at the front side of the upper end of the gantry body 6, and a manipulator 8 is installed in the middle of the upper end of the gantry body 6;

[0030] In this embodiment: the gantry body 6 is mainly driven electrically to move along the second slide slot 5 to the front side of the conveyor belt 4, and then the manipulator 8 is used to pick up the goods and put them at the lower end of the scanner 7 for precise scanning and processing to determine the type of goods. Then the gantry body 6 is driven to move backward along the conveyor belt 4 track, and the picked up goods are thrown to the left and right ends of the conveyor belt 4 by the manipulator 8 for classification and processing. Some of the goods will be transported to the rear side of the conveyor belt 4 by the gantry body 6 and put down, and continue to be transported backward through the conveyor belt 4.

[0031] Working principle: When in use, when the goods fall quickly into the upper end of the protective net body 1, the protective net body 1 will generate an impact force from top to bottom, and the impact force is transmitted to the elastic bending steel plate 203 through the mounting plate 201, causing the elastic bending steel plate 203 to be slightly bent under the force, and the upper end of the elastic bending steel plate 203 slides inside the first slide groove 202, and the protective net body 1 moves downward slightly, causing the distance between the protective net body 1 and the conveyor belt 4 to shorten, and the elastic bending steel plates 203 at the four ends below the protective net body 1 are slightly bent to buffer the impact force brought by the goods, and then the elastic bending steel plates 203 are slightly bent. The bent steel plate 203 recovers under the action of its own elastic force. While the distance between the protective net body 1 and the conveyor belt 4 is shortened, the second connecting block 208 transmission connecting rod 209 pushes the first connecting block 207 and the two sets of sleeves 205 to move inward on the cylindrical rod 204, causing the spring 206 to contract. By converting the impact force of the falling goods into the squeezing force between the sleeves 205 on the spring 206, the offsetting effect of the impact force is further improved, achieving the buffering effect between the protective net body 1 and the conveyor belt 4, and reducing the damage to the conveyor belt 4 caused by the impact force.
