Description

Technical Field

[0001] The utility model relates to the fields of catenary conveying and automatic production, and particularly relates to a front-back clamping type catenary positioning device. Background Art

[0002] The suspension chain device is a device for continuously conveying products in space. The suspension chain drives the catenary hanging rack to hang products and run along the catenary track. It can go uphill, downhill and turn in space. The layout method is free and flexible, and it occupies a small area. It is often used in mass production operations in industries such as machinery, automobiles, electronics, household appliances, light industry, food, and chemical industry. By adopting aerial conveying, its conveying speed can be adjusted, which is beneficial to operations such as mechanical assembly. It is a kind of conveying equipment widely used in domestic enterprises. The suspension chain can continuously transport products to high-temperature drying rooms, harmful gas areas, powder spraying rooms, freezers, etc., to complete production processes that are difficult for manual operation, thereby improving the working conditions of workers. In addition, this equipment also has the advantages of less power consumption, low noise, stable operation, easy operation, and safe use.

[0003] The suspension chain device still has some deficiencies. When it is necessary to accurately stop the products on the catenary hanging rack at a specified position, it is impossible to achieve this only by the suspension chain. In some industrial fields, the catenary transportation is coordinated with a manipulator. After the catenary decelerates and stops, the manipulator grabs the products on the catenary hanging rack, but this requires the catenary to be accurately positioned. Currently, the existing device for accurately positioning the hanging rack is in the form of left-right clamping, and its limitation is that it can only be applied to smaller and narrower hanging racks. Summary of the Invention

[0011] When the detection plate on the catenary hanger passes through the second deceleration and stop device, a detection signal is generated and sent to the catenary control system, so that the catenary control system controls the catenary to stop.

The inclined support arm is connected to the fixing plate through a cross arm; a driving device is installed at the lower end of the first fixing frame, and a clamping plate is installed at the output end of the driving device.

[0013] Further, the driving device adopts a cylinder.

[0014] Further, the deceleration and stop device adopts a sensor with a "concave" shape structure. A detection plate is arranged on the side of the catenary hanger. When the detection plate passes through the sensor, the sensor will generate a detection signal.

Multiple groups of fixing holes are arranged on the main body frame; the height position of the deceleration and stop device is adjusted through the first adjusting screw, and the horizontal position of the deceleration and stop device is adjusted by matching the upper end of the first adjusting screw with different fixing holes.

[0020] Further, the detection device adopts a laser sensor.

[0021] Further, the rail hanging plate is fixedly installed at the lower part of the main body frame for installing the catenary track; the upper end of the catenary hanger is installed on the catenary track through a catenary chain. The lower end of the catenary hanger hoists the product. Under the control of the catenary control system, the driving catenary chain drives the catenary hanger to move on the catenary track.

[0022] Compared with the prior art, the utility model has the following technical features:

[0023] When the catenary hanger needs to stop at a specific position, the catenary positioning device will clamp the hanger, thereby realizing the precise positioning of the products on the hanger, facilitating the operation of subsequent equipment, and improving the production efficiency and quality of the products. Applying this device to the transportation or automated production industry and using it in combination with equipment such as manipulators can greatly improve the production efficiency of products.

Under the control of the catenary control system, the driving suspension chain drives the catenary hanger 11 to move on the catenary track 10.

[0029] The first fixing bracket 2 and the second fixing bracket 3 are respectively arranged on both sides of the main body frame 1. Among them, clamping mechanisms 6 which cooperate with each other are installed at the lower ends of the first fixing bracket 2 and the second fixing bracket 3 for clamping and fixing the products hoisted at the lower ends of the catenary hanging brackets 11. In this embodiment, there is an inclined support arm 31 at the lower end of the second fixing bracket 3, and the inclined support arm 31 is connected to a fixing plate 61 through a cross arm; a driving device 5 is installed at the lower end of the first fixing bracket 2, and a clamping plate is installed at the output end of the driving device 5.

[0030] A pair of deceleration stop devices 4 are arranged at intervals below the main body frame 1. When the detection plate 12 on the catenary hanging bracket 11 passes through the first deceleration stop device 4, this deceleration stop device 4 generates a detection signal and sends it to the suspension chain control system, and the suspension chain control system controls the suspension chain to drive the catenary hanging bracket 11 to decelerate; when the detection plate 12 on the catenary hanging bracket 11 passes through the second deceleration stop device 4, this deceleration stop device 4 generates a detection signal and sends it to the suspension chain control system, and the suspension chain control system controls the suspension chain to stop moving; in this solution, by controlling the catenary hanging bracket 11 to decelerate before stopping, the stopping position of the catenary hanging bracket 11 can be made more accurate and gentle, so as to ensure that the product can stop accurately at the specified position. Then, the clamping mechanism 6 is used to clamp and fix the product, and then it can cooperate with equipment such as a manipulator to realize further processing of the product.

[0031] In this embodiment, the deceleration stop device 4 adopts a sensor with a "concave" shape structure, and this sensor can adopt, for example, an optoelectronic sensor, a laser sensor, a Hall sensor, etc.; a detection plate 12 is arranged on the side of the catenary hanging bracket 11, and when the detection plate 12 passes through the sensor, the sensor will generate a detection signal.

Among the pair of detection devices 7, one is a transmitting end and one is a receiving end; when no product passes through, the value of the information received by the receiving end from the transmitting end is constant; when a product passes through, due to the blockage of the product, the value of the information received by the receiving end changes, indicating that there is a product on the catenary hanger 11. Through this setting, it is possible to detect whether there is a product on the catenary hanger 11 after the catenary hanger 11 stops.

[0034] Among them, the detection device can adopt a laser sensor; the detection device 7 is installed on the first fixing bracket 2 and the second fixing bracket 3 through the second adjusting screw 9, and multiple groups of fixing holes matching with it are also distributed on the first fixing bracket 2 and the second fixing bracket 3; the height position and horizontal position of the detection device 7 are adjusted through the second adjusting screw 9.

[0035] Using the positioning device provided in the above-mentioned embodiment of the present utility model, when the catenary hanger 11 suspends the product and moves through the designated position where the positioning device is installed on the production line, the deceleration stop device 4 is used to decelerate first and then stop smoothly. Then, it is detected whether there is a product on the catenary hanger 11 through the detection device 7. When there is a product, the product can be clamped by the clamping mechanism 6, and then further processed in cooperation with other equipment such as a manipulator; after processing, the fixation of the product is released by the clamping mechanism 6, and then the suspension chain control system controls the suspension chain to continue to move, and the product is carried to the downstream of the production line through the catenary hanger 11.
