Technical Field
[0001] The utility model discloses a roller conveyor line tray in-place signal sensing device, which relates to the technical field of conveyor devices, and in particular to a roller conveyor line tray in-place signal sensing device. Background Art
[0002] Roller conveyor line is a common logistics transportation and production automation equipment, mainly used to transport various items, including raw materials, semi-finished products and finished products in the production process. It can automatically transport items from one place to another, eliminating the trouble of manual handling and improving production efficiency. At the same time, roller conveyor line can also realize real-time monitoring and management of items to ensure the controllability and safety of the production process. Roller conveyor line can be used for the transportation of flat bottom items, such as turnover boxes, cartons, wooden boxes, pallet goods and plate-shaped goods, etc., which can help complete the transportation and transfer of goods and the transportation and sorting of goods. When the roller conveyor line with automatic control is transporting pallets, when the pallet is transported to the designated station, it is generally necessary to provide the automatic control system with an in-place signal so as to carry out the next set action. At present, photoelectric switches are generally used to illuminate the surface of the pallet and send signals according to the reflection. However, due to differences in the materials and dimensions of the pallets, there are problems such as no signal or wrong signal when using photoelectric switches, which causes the corresponding stations of the automatic conveyor line to not operate or to operate incorrectly, thus affecting the overall efficiency of the automatic conveyor line, and even causing the entire automatic conveyor line to shut down, and even causing dangerous accidents. At the same time, the purchase cost of photoelectric switches is high, resulting in high manufacturing, use and maintenance costs of the automatic conveyor line.

[0008] Further, a proximity switch is mounted on the slide;
[0009] Furthermore, one end of the unpowered roller is fixed to the frame side wall of the roller conveyor line away from the chute by bolts, and the other end is equipped with a sliding structure;
[0010] Furthermore, the sliding structure is installed in the slide groove and can slide up and down in the slide groove;
[0011] Furthermore, the sliding structure is also connected to a reset structure assembled on the bottom of the slide groove;
[0012] Furthermore, the sliding structure slides up and down along the slide slot to approach / separate from the proximity switch, triggering the proximity switch to transmit an in-position signal to an external automatic control system.
[0013] Furthermore, the chute is a U-shaped structure consisting of a short vertical plate, a bottom plate and a guide groove;
[0014] Furthermore, a proximity switch is mounted on the short vertical plate;
[0015] Furthermore, a reset structure is mounted on the bottom plate, and the reset structure is connected to the bottom end of the sliding structure;
[0016] Furthermore, a sliding part of the sliding structure is installed in the guide groove to provide a guide for the sliding structure to slide up and down.
[0017] Furthermore, a limited position structure is provided on the bottom plate;
[0018] Furthermore, the limiting structure includes: a limiting screw and a limiting nut. The limiting screw is screwed on the bottom plate and is fixed by the limiting nut to provide a limit for the sliding downward movement of the sliding structure.
[0019] Furthermore, the sliding structure includes: an L-shaped bracket and a bearing;
[0020] Furthermore, two bearings are longitudinally mounted on the outer side of the vertical plate of the L-shaped bracket, and the bearings are mounted inside the guide groove to ensure that the sliding structure slides up and down along the guide groove;
[0021] Further, the inner side of the vertical plate of the L-shaped bracket is connected to the end of the unpowered roller;
[0022] Further, the transverse plate of the L-shaped bracket is connected to the reset structure;
[0023] Furthermore, under the support of the reset structure, the L-shaped bracket makes one end of the unpowered roller connected to the L-shaped bracket higher than the other end; the horizontal plane of the unpowered roller is arranged in an oblique line.
[0024] Furthermore, the end of the horizontal plate faces the proximity switch when moving downward, providing a position signal for the proximity switch.
[0025] Further, the reset structure includes: a guide screw, a washer, a spring and an adjustment nut;
[0026] Furthermore, the guide screw passes downward from the upper part of the horizontal plate, and a spring is sleeved on the guide screw at the lower part of the horizontal plate;
[0027] Further, the guide screw is assembled through the adjusting nut after passing through the base plate;

The bearing can slide up and down in the U-shaped guide groove of the slide groove, and the slide groove limits the diameter direction of the bearing. The slide groove is fixed to the side wall of the frame on the other side of the roller conveyor line with bolts. When a pallet is pressed to the unpowered roller higher than the roller of the roller conveyor line, the unpowered roller is placed on the side wall of the frame of the roller conveyor line. When the upper outer cylindrical surface is moved, the weight of the pallet presses the higher side of the unpowered roller, driving the L-shaped bracket to slide downward along the guide screw and compressing the spring at the same time. When the L-shaped bracket slides downward and contacts the limit screw, it stops sliding downward. The proximity switch arranged on one side of the short vertical plate of the slide senses the cross plate of the L-shaped bracket and sends an in-position signal to the automatic control system, allowing the automatic conveyor line to proceed to the next step. When the pallet is removed, the compressed spring begins to rebound and drives the L-shaped bracket to move upward, and the L-shaped bracket drives the unpowered roller to return to its initial position.
