Description

Technical Field

[0001] The invention belongs to the technical field of roller processing, and in particular relates to an automatic feeding device for bearing rollers. Background Art

[0002] In an automated production line, rollers need to be arranged on a conveyor to enter the next process. When the rollers are fed by a loader, the rollers are in a disordered state in the material channel due to the uncertain arrangement of the rollers. Especially when rollers of the same length and diameter are fed, the roller states cannot be effectively distinguished during feeding due to the same length and diameter, which makes it inconvenient for the robot to grab or the next process to process, affecting the entire automated production process and production efficiency. Summary of the invention

[0003] In view of the defects of the above-mentioned prior art, the purpose of the present invention is to provide an automatic feeding device for bearing rollers, which can screen rollers in different states so that the rollers entering the next process are in an orderly state, thereby improving the roller processing efficiency.

[0019] In order to make the structure and function of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] See attached Figure 1-3 The automatic feeding device for bearing rollers comprises a conveyor belt 1 and a plurality of rollers arranged on the conveyor belt. An image recognition sensor 4 for detecting the rollers to be tested and a sorting cylinder 6 for pushing the rollers to be tested are arranged at the sorting station on the conveyor belt. The image recognition sensor 4 is fixed to one side of the conveyor belt through a fixing seat 11. A material channel 10 is arranged at the sorting station of the conveyor belt 1. The material channel 10 is connected to a material box 2. The telescopic end of the sorting cylinder 6 is arranged corresponding to the entrance of the material channel. The image recognition sensor 4 is connected to the sorting cylinder 6 through a signal to control the extension and retraction of the telescopic end of the sorting cylinder 6.

[0021] Furthermore, a number of rollers to be loaded are placed in the material box 2, and a loading push plate 3 for feeding the rollers into the conveyor is provided in the material box. The loading push plate 3 is connected to the inner wall of the material box 2 through a slider guide rail, and the lower part of the loading push plate 3 is driven by a hydraulic cylinder to reciprocate up and down. The upper surface of the loading push plate is tilted, and the tilting direction is downward toward the conveyor belt, so that the rollers can roll onto the conveyor belt. The side baffles of the conveyor belt 1 are welded to the material box 2, and the surface of the conveyor belt is slightly lower than the edge of the material box. The rollers of the material box are pushed upward by the loading push plate 3, and the rollers slide into the conveyor belt 1. There are baffles 12 on both sides of the conveyor belt, which together constitute the conveying material channel, wherein the baffle 12 on one side of the welded material box is flush with the height of the material box 2, and the baffle 12 on the side away from the material box is higher than the conveying surface of the conveyor belt to prevent the rollers from being offside.

[0022] Furthermore, the material channel 10 is arranged to be tilted downward from the entrance to the exit, so that the rollers in the wrong state can roll down to the material box 2 for re-loading.

[0023] Furthermore, the sorting cylinder is fixed to one side of the conveying device through a cylinder seat, and a V-shaped groove for positioning the roller is provided on the cylinder seat. A push-up cylinder 9 for pushing up the roller is provided below the V-shaped groove.

[0024] Furthermore, the telescopic end of the sorting cylinder 6 is provided with a sorting baffle 7 for blocking the roller from moving forward. The sorting baffle is a "concave"-shaped structure. The groove in the middle of the sorting baffle cooperates with the roller for positioning. The side plates on both sides of the sorting baffle drive the roller to move with the extension or contraction of the telescopic end of the sorting cylinder. The sorting cylinder is connected to the side plates of the sorting baffle 7, and the cylinder seat of the sorting cylinder and the material channel are arranged perpendicular to the conveying surface of the conveyor belt. When the sorting cylinder is not moving, the sorting baffle 7 is located on the sorting position of the roller, hindering the roller from moving forward and causing the roller to enter the groove of the sorting baffle. After the sorting cylinder receives the detection signal from the image recognition sensor 4, if the detection is qualified, the sorting cylinder 6 contracts, and the sorting baffle 7 pushes the roller to the V-groove, and the upward push cylinder 9 under the V-groove pushes the roller upward for the robot to grab; if the detection is unqualified, the sorting cylinder 6 extends, and the sorting baffle 7 pushes the roller into the material channel 10, and the roller rolls down to the material box 2 for re-loading.

[0025] The working principle of the bearing roller automatic feeding device of the present invention is as follows: taking lathe feeding as an example, the roller is poured into the material box 2, and the feeding push plate 3 pushes the roller into the conveyor belt 1. The roller in the conveyor belt passes through the image recognition sensor 4, and the image recognition sensor 4 transmits the signal to the sorting cylinder 6 according to the state of the roller. If the roller is in state A and state B in the material channel, the sorting cylinder 6 extends and pushes the roller into the material channel 10, and the roller returns to the material box 2, and is pushed into the conveyor belt 1 by the feeding push plate 3, and is recognized by the image recognition sensor 4 again; if the roller is in state C in the material channel, the sorting cylinder 6 contracts, and the roller falls into the V-shaped groove 8, and the upward push cylinder 9 pushes the roller out. At this time, the manipulator grabs the roller and sends the roller into the chuck of the CNC lathe for lathe processing, completing one grab. Repeat the above actions to complete the automatic roller feeding.

[0026] The beneficial effects of the present invention are as follows: the device can sort rollers within the range of a minimum specification of Φ30x30 and a maximum specification of Φ65x65; rollers of different specifications can be sorted without changing any tooling; and rollers can be automatically grabbed by a robot without manual intervention, thereby realizing automated roller feeding.

[0027] It should be noted that the image recognition sensor 4 used in this embodiment is Keyence Co., Ltd., sensor probe IV-500MA; sensor controller IV-G10 (main device), which is only one of the sensor models proposed for the implementation of the technical solution. Other types of image recognition sensors on the market that can be used for this device are all acceptable. In addition, this embodiment is for sorting rollers with the same length and diameter, and the roller state is identified by the image recognition sensor. This is an extreme condition. When sorting rollers with different lengths and diameters, infrared sensors, photoelectric sensors and other components can also be used to replace the image recognition sensor for sorting and working, as long as the requirements for identifying the roller state are met.

[0028] The above examples are only the best embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments, and many variations are possible. All variations that can be directly derived or associated with the contents disclosed by a person skilled in the art should be considered as the protection scope of the present invention.
