Positioning method and apparatus for pushing carbon block from transfer line rotary platform to receiving arrangement

Abstract

The invention discloses a locating method and device of coke block from transmission line rotary table to receiving device, which is characterized by the following: adapting three couples of photoelectric switch to detect the coke block on the rotary table; setting two couples of photoelectric switch on two edges of rotary table separately; making the right rotation coke block lying between two couples of photoelectric switch axle without detecting by switch; setting the third couples of photoelectric switch between two couples of photoelectric switch to detect the coke block on the rotary table. The invention can detect and locate the coke block, which prevents coke block from colliding or blocking when the coke is pushed to the receiving device by rotary table.

Description

Technical field: [0001] The invention relates to a positioning method and device for pushing carbon blocks from a conveyor line rotary platform to a receiving device in carbon plant production, and belongs to the technical field of accurate positioning and detection of carbon blocks in carbon block transportation. Background technique: [0002] In the automatic production process of the carbon plant, the carbon block sometimes needs to be rotated 90 degrees or 180 degrees during the transportation process of the carbon block in the assembly and disassembly process to meet the requirements of the carbon block transportation. For example, when the carbon blocks are grouped on the marshalling machine, the carbon blocks need to be rotated 90 degrees on the rotating platform. When the carbon block is ungrouped on the ungrouping machine, the carbon block sometimes needs to be rotated 180 degrees on the rotating platform. At present, in the existing technology, only a pair of phot...

Problems solved by technology

There are two situations that may occur here. 1) Due to a malfunction, the carbon block cannot be fully pushed onto the rotating platform, and at this time, the oil cylinder that has been pushed to the rotating platform returns to its original position, and the photoelectric switch on the rotating platform is sensed to the rotating platform. There are carbon blocks, but they are not fully in place. At this time, the three conditions for pushing out are met. If the carbon blocks on the rotating platform are pushed out of the cylinder, the carbon blocks will not be able to enter the carbon block receiving device smoothly, and the carbon blocks will be stuck in the receiving device. 2) After the turntable has been used in production for a period of time, the surface of the turntable will become very smooth due to the carbon blocks constantly entering and leaving the rotating platform and rubbing against the rotating platform. It will cause the carbon block on the turntable to continue to move in the direction of rotation due to inertia when the turntable stops rotating, making the carbon block obliquely on the turntable. If the angle of the carbon block is too large, it is also sufficient to push out The three conditions for the carbon block, if the carbon block on the rotating platform is pushed out of the cylinder, the carbon block will not be able to enter the carbon block receiving device smoothly, and will be held in front of the receiving device, and the oil cylinder will be suffocated, or even if the carbon block enters The receiving unit may also cause the charcoal to jam in the receiving unit

These accidents have already occurred in the production plant, which brought inconvenience to equipment maintenance and production, and caused great losses

Due to the inaccurate detection and positioning of the position of the carbon block when the carbon block is pushed from the conveyor line rotary platform to the receiving device in the existing technology, the work reliability is poor and it cannot meet the needs of production.
