DETAILED DESCRIPTION

[0025] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0026] Reference Figures 1 to 4 A material conveying device, comprising a material conveying mechanism 1 and a limit detection mechanism 2; the material conveying mechanism 1 is used to convey material 3 from its first end to the second end; the limit detection mechanism 2 is arranged at the second end of the material conveying mechanism 1, and is used to detect whether the material 3 is conveyed in place and limit, which comprises a rotating shaft 2.1, a baffle 2.2 and an infrared detection mechanism; the rotating shaft 2.1 is arranged in the conveying plane of the material conveying mechanism 1; the baffle 2.2 is arranged in multiple groups on the rotating shaft 2.1 at intervals, and the baffle 2.2 is rotatably arranged around the rotating shaft 2.1, and is used to rotate when the baffle 2.2 is pushed by the material 3; the infrared detection mechanism comprises a transmitter 2.3 and a receiver 2.4 arranged at both ends of the rotating shaft 2.1 respectively, the transmitter 2.3 is used to emit laser 4 to the receiver 2.4, and the baffle 2.2 can be arranged between the transmitter 2.3 and the receiver 2.4.

[0027] Through the above material limiting detection mechanism, when the small mass of the plate material is conveyed to the position, only a few rotating plates need to be pushed, at least one baffle is pushed, the problem that the traditional detection mechanism is easy to be pushed by the small material without enough kinetic energy is solved, detection is carried out through infrared emission and receiving switches, as long as any baffle can be turned over, the light path can be blocked, so that the state of the sensor is changed to achieve the purpose of detection; the infrared rays are blocked by the baffle, rather than being blocked by the material at the fixed position to carry out detection, the situation that the thin plate material is not easy to be detected is solved, and the position of the sensor does not need to be changed, the sensitivity and universality of the device are improved.

[0028] Reference Figure 2 The baffle 2.2 includes a connecting part 2.21 and a shielding part 2.22, the connecting part 2.21 is provided with a through hole matched with the rotating shaft 2.1, and the baffle 2.2 is rotatably sleeved on the rotating shaft 2.1; the shielding part 2.22 is fixedly connected with the connecting part 2.21, and is used for rotating with the connecting part 2.21 around the rotating shaft 2.1 to between the receiver 2.4 and the emitter 2.3. The shielding part 2.22 and the connecting part 2.21 are an integral thin plate structure. The weight of the shielding part 2.22 is greater than that of the connecting part 2.21, and is used for maintaining a natural downward state when the baffle 2.2 is static.

[0029] The rotating shaft 2.1 is parallel to the roller 1.1 of the material conveying mechanism 1, and the top end of the connecting part 2.21 is higher than the top end of the roller 1.1. Through the weight design of the baffle, the baffle maintains vertical in the natural state, avoids blocking infrared rays, and triggers the sensor. After triggering the rotation, the material is removed, and the baffle can be automatically reset.

[0030] The thin plate structure makes the material, especially the material with small thickness and small weight, easy to trigger, and the sensitivity is greatly improved. According to the width and other parameters of the material conveying mechanism, the number of baffles can be appropriately adjusted, the structure size of the baffle does not need to be redesigned, and the rotation of the baffle is not affected. Small objects can be detected on a conveying line with a large width, and the universality of the device is greatly improved.

[0031] Reference Figure 3 and Figure 4 Under normal circumstances, the emitter emits infrared light without obstacles to the receiver, when any baffle is turned over by the plate material, the light is blocked, at this time the state of the receiver changes, and the purpose of plate material position detection is achieved. When the plate material is removed or the end of the plate material advances to the front of the baffle (i.e. the entire plate material crosses the baffle position), according to the instruction, the baffle on the material detection mechanism is reset under the action of gravity.

[0032] The sleeves 2.5 are arranged between the groups of baffle plates 2.2, and are used to limit the axial movement of the baffle plates 2.2 along the rotating shaft 2.1. The sleeves ensure that the distance and interval between the baffle plates are uniform, and the interval distance of the baffle plates can be adjusted according to the use of different specifications of sleeves, so as to adapt to the detection of different materials.

[0033] The material conveying mechanism 1 and the position limiting detection mechanism 2 are connected with the controller.

[0034] Through the controller, the baffle plates rotate to block the infrared laser emitted by the emitter, trigger the receiver, and then control the material conveying mechanism to start and stop and other operations, so as to avoid the material from continuing to advance.

[0035] The above only describes the preferred embodiments of the present application, and is not used to limit the present application. For those skilled in the art, various changes and modifications can be made within the spirit and principle of the present application.
