Description

technical field

The invention belongs to the application of automatic logistics transportation in the field of locomotive maintenance, in particular to a bearing transportation and switching device.

Background technique

In the past, the transportation of bearings was manually selected from the warehouse according to the demand list. The inner diameter of the bearings was also measured manually, and the handling was also carried out manually. This was not only time-consuming and laborious, but also the bearings were easy to remember and misremember. Repeated work, lead to low work efficiency.

Among the existing improved technologies, Document 1: "Development and Innovation of Electromechanical Products", January 2017, Volume 30, Issue 1, Page 72, proposes a three-dimensional warehouse control system for train bearings. The disclosed bearing control is as follows : The bearings are stored in the three-dimensional warehouse, transported by the transport trolley RGV, transferred by the scissor lift mechanism, and finally roll the bearing from the RGV to the press-fitting station through the slide rail. Due to the limitation of the RGV's ability to access bearings, this transportation method can only take two bearings at a time; moreover, the RGV's running track is far away, and the transportation efficiency is slow; The lifting mechanism interferes with the exit port.

According to the application of the computerized bearing selection system, the database bearing inner diameter size manages the bearings in stock, and according to the size of the wheel axle, the optimal matching bearing is selected in the database. Convey to the press-fitting station according to the conveying beat and sequence; the position of each bearing in the queue can not be missed or misselected, and the entry and output process of the bearing on the conveying line needs to be strictly checked to ensure the bearing Correctly transported to the designated press-fitting station. The present invention proposes an optimized transportation scheme for the transportation and transfer of bearings, adopts the method of chain plate conveyor to carry out long-distance automatic selection and transportation; the transportation line still uses the underground form, and the chain is installed in the underground roadway. For the slab conveyor, the underground roadway is provided with openings at the exit of the stacker, and the unloading bearing of the stacker is sent to the conveyor line through the lifting and receiving mechanism at the warehouse mouth; at the right-angle corner of the conveyor line, the lifting The rotating material receiving mechanism changes the line of the bearing to realize a right-angle turn; at the entrance of the slideway of the pressing station, the underground conveying line is opened, and the bearing is sorted from the conveying line through the lifting and pushing mechanism, and it is lifted out of the ground to the slideway.

Because the speed of the chain conveyor is relatively fast, according to the matching of the receiving frequency of the lifting and receiving mechanism with the cycle speed of the conveyor line, it can match the unloading frequency of the stacker. Arrange the bearings from the three-dimensional warehouse to the conveyor line in a logical order. There is no human intervention in the process, reducing the chance of human error.

The longitudinal bearing conveying line, as shown on the right side of Figure 2, adopts a chain type with sprockets on both sides and a single side plate, which rotates circularly in one direction, and carrier groups are installed symmetrically and equidistantly on the two chains, and the carriers adopt The split-type inverted "eight"-shaped nylon block is symmetrically installed on the two chains; there are lifting and pushing mechanisms on the top of the sprockets on both sides;

Lifting chains are set on both sides, and the lifting motor drives the lifting chain to go up and down. The material receiving fixture A is fixedly installed on the chain and rises and falls simultaneously with the lifting chain; the material receiving fixture A can be raised to the unloading height of the stacker, and the stacker puts the bearing Descend to the level of the conveyor line and place the bearing on the bearing carrier of the conveyor line.

The material receiving fixture A is an open hole type. When the lifting material receiving mechanism rises to the ground outlet, the pallet fork of the stacker carries the bearing and protrudes directly above the material receiving fixture A, and the fork descends until the bearing is stuck on the material receiving fixture. A is separated from the fork, and the fork is retracted to complete the outbound task of the stacker; after the stacker unloads the bearing to the receiving fixture A, it lowers the bearing to a low position along with the lifting chain, and waits for the movement of the horizontal bearing conveyor line.
