Description

Technical Field

[0001] The utility model relates to the technical field of manipulators, in particular to a material transfer warehouse robot used for a belt conveyor line. Background Art

[0002] Belt conveyor is the main equipment for modern bulk material transportation. It is widely used in many industries such as metallurgy, mining, coal, ports, chemical industry, water conservancy, and electric power. Its reliable operation is a necessary condition for the normal operation of belt conveyor. With the widespread application of wide bandwidth, large capacity, high efficiency and energy saving, economical and environmentally friendly belt conveyors, the requirements for the use of rollers are getting higher and higher.

[0003] With the continuous development of industry, in terms of warehouse storage, objects are transported to the required workstations through belt conveyors, and warehouse robots are also widely used in the transportation of materials to transport the required materials to the required workstations. Existing warehouse robots are provided with conveyor rollers, and the conveyor rollers have motors that drive the rollers to actively rotate and rotate synchronously with the conveyor belts. The warehouse robots need to install motors, transmission mechanisms that drive the rollers to rotate, and larger batteries, etc. This increases the weight of the warehouse robots themselves, thereby greatly reducing the load capacity of objects and reducing work efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to solve the problem that the existing warehouse robot is provided with a conveyor roller shaft, and the conveyor roller shaft has a motor that drives the roller shaft to actively rotate and rotate synchronously with the conveyor belt, the warehouse robot needs to install a motor, a transmission mechanism for driving the roller shaft to rotate, and a larger battery, etc., which increases the weight of the warehouse robot itself, thereby greatly reducing the load capacity of objects and reducing the work efficiency. A material transfer warehouse robot for a belt conveyor line is now provided.

[0005] The utility model solves the technical problem by adopting the following technical scheme: a material transfer warehouse robot for belt conveyor line, comprising a vehicle body, a pressure roller, a connecting rod and an intermediate roller, a plurality of conveying rollers are arranged on the vehicle body for lateral rotation, the plurality of conveying rollers are mutually connected for transmission and can rotate in the same direction, the connecting rod is rotatably arranged on the vehicle body, the pressure roller and the intermediate roller are both rotatably arranged on the connecting rod, the rotation center point of the connecting rod is located between the pressure roller and the intermediate roller, the pressure roller and the intermediate roller are mutually connected for rotation and can rotate in the same direction, when the pressure roller contacts with the external belt conveyor mechanism, the pressure roller and the intermediate roller are located below the conveying roller, the pressure roller drives the connecting rod to rotate and drives the intermediate roller to rotate, when the intermediate roller contacts with the conveying roller, the intermediate roller drives the plurality of conveying rollers to rotate in the same direction.

[0006] The utility model makes the pressure roller on the vehicle body contact with the external belt conveyor mechanism and drives the connecting rod to rotate. At the same time, the pressure roller drives the intermediate roller to rotate in the same direction, and then makes the intermediate roller contact with the conveying roller, so that the belt conveyor mechanism and the conveying roller rotate in the same direction, and also realizes the conveying of objects to the vehicle body or output to the belt conveyor mechanism. The external belt conveyor mechanism provides power to rotate the conveying roller, and passive conveying is realized. In this way, there is no need to install a motor and a complex transmission mechanism, and there is no need to install a large and heavy battery, which reduces the overall weight of the vehicle body, increases the load capacity of the vehicle body, and improves work efficiency.

[0007] In order to prevent objects from falling out from the end of the conveyor roller away from the belt conveyor mechanism, further, a first limit plate is provided at the end of the vehicle body where the conveyor roller is away from the belt conveyor mechanism, and the first limit plate has a vertical height greater than the height of the conveyor roller. By providing the first limit plate at the end of the vehicle body where the conveyor roller is away from the belt conveyor mechanism, the height of the first limit plate is higher than the height of the conveyor roller, so that the first limit plate limits the goods on the conveyor roller, ensuring stable and reliable transportation of objects.

[0008] In order to prevent objects from falling out from one end of the conveying roller close to the belt conveyor mechanism, a second limit plate is further provided on the frame along the vertical sliding direction, and several of the conveying rollers are located between the first limit plate and the second limit plate, and the second limit plate is provided on the connecting rod. When the pressure roller contacts the belt conveyor mechanism, the connecting rod rotates and drives the second limit plate to gradually descend on the vehicle body. When the intermediate roller contacts the conveying roller, the height of the second limit plate is lower than the height of the conveying roller. A reset mechanism for resetting the second limit plate is provided between the second limit plate and the vehicle body. When the pressure roller separates from the belt conveyor mechanism, the reset mechanism drives the second limit plate to rise and the second limit plate drives the connecting rod to rotate, and realizes the separation of the intermediate roller from the conveying roller, and the second limit plate rises and is higher than the conveying roller. By arranging a second limit plate on the vehicle body, and the conveying roller is located between the first limit plate and the second limit plate, when the middle roller contacts the conveyor, the second limit plate is driven to descend and is lower than the conveying roller. When the pressure roller disengages from the belt conveyor mechanism, the reset mechanism drives the second limit plate to rise and is higher than the conveying roller, thereby limiting the position of the object. This will neither affect the limiting of the object during transportation nor the conveying of the object.

[0009] In order to realize the reset of the second limit plate by the reset mechanism, the reset mechanism further comprises a spring, one end of which is arranged on the vehicle body, and the other end of which is arranged on the second limit plate. The reset mechanism is realized by the spring, and its structure is simple, and it is easy to install and maintain.

[0010] In order to realize that the connecting rod drives the second limit plate to rise or fall, further, a limit pin is provided on the second limit plate, and a limit slot is provided on the connecting rod along its axial direction, and the limit pin is arranged in the limit slot. By providing the limit slot on the connecting rod and cooperating with the limit pin on the second limit slot, the connecting rod drives the second limit plate to rise or fall.

[0011] In order to enable the second limit plate to slide on the vehicle body, further, a slide groove is provided on the vehicle body in the vertical direction, the slide groove matches the second limit plate, and the second limit plate is slidably arranged in the slide groove. The slide groove on the vehicle body cooperates with the second limit plate to enable the second limit plate to slide on the vehicle body.

[0012] The beneficial effect of the utility model is that when the material transfer warehouse robot for the belt conveyor line of the utility model is in use, the pressure roller on the vehicle body contacts the external belt conveyor mechanism and drives the connecting rod to rotate, and at the same time, the pressure roller drives the intermediate roller to rotate in the same direction, and then makes the intermediate roller contact with the conveying roller, so that the belt conveying mechanism and the conveying roller rotate in the same direction, and also realizes that the objects are transported to the vehicle body or output to the belt conveyor mechanism, and the external belt conveyor mechanism provides power to rotate the conveying roller to realize passive transportation, so that there is no need to install a motor and a complex transmission mechanism, and there is no need to install a large and heavy battery, which reduces the overall weight of the vehicle body, increases the load capacity of the vehicle body, and improves the work efficiency, avoids the problem that the existing warehouse robot is provided with a conveying roller shaft, and the conveying roller shaft has a motor that drives the roller shaft to rotate actively and rotates synchronously with the conveyor belt, and the warehouse robot needs to install a motor, a transmission mechanism for driving the roller shaft to rotate, and a larger battery, etc., which increases the weight of the warehouse robot itself, thereby greatly reducing the load capacity of the objects and reducing the work efficiency.
