Description

one

The invention relates to industrial transport and can be used for transporting and assembling products in the engineering industry and in other branches of the national economy.

A walking conveyor for transporting products is known, which consists of an I movable frame located between the fixed beams, a pneumatic cylinder for longitudinal movement of the frame, eccentrics with support rollers and a pneumatic cylinder for turning eccentrics. The eccentrics and the support rollers are connected in g. The frame with the loads laid on it rises and mixes up by the stroke of the pneumatic cylinder, then it lowers, the loads are placed on the beams, and the frame returns to its original position T.

Closest to the proposed invention to the technical essence and the achieved result is a shagayushchy conveyor containing a fixed and movable frame 1, mechanisms for lifting and moving the movable frame 2.

The disadvantages of these conveyors are that when the movable frame is raised and lowered, it moves in a horizontal plane, since the frame, being pivotally connected to the cylinder of the movement mechanism, rises or falls along the arc. This leads to a violation of positioning accuracy when moving products.

The aim of the invention is to ensure the accuracy of the positioning of the moved articles.

This is achieved by the fact that the conveyor is equipped with a stabilization mechanism for lifting the movable frame, made in the form of a bracket mounted on the movable frame with vertical guides and traverses with sliders pivotally mounted on it, placed in the guides, the traverse being pivotally connected to the frame moving mechanism.

FIG. 1 shows a walking conveyor; in FIG. 2 - the same plan view; in fig. 3 shows section A-A in FIG. I; in fig. 4 shows a section BB in FIG. 2; in fig. 5 is a section bb In FIG. 3 A walking conveyor consists of a fixed frame consisting of a metal structure consisting of separate sections 1, 2, 3 and 4 not connected to each other. It is equipped with a lifting mechanism of a movable frame 5 consisting of power cylinders 6, a rod 7 which by means of cranks 8 is connected to the shaft 9. On the shafts, angular levers 10 rigidly azixpen, pivotally connected to each other by means of 1 i and equipped with rollers 12, along which movable frame 5 moves on rails 13 On fixed frame section 3 a movable frame is mounted 5 which The motor cylinder 14 is mounted on the trunnions 15. The cylinder rod 16 is pivotally connected via a fork 17 to a lifting stabilization mechanism 18. The stabilizing mechanism consists of a crosspiece 19, on which the sliders 20 are hingedly mounted. They are placed in vertical guides 21 and 22 of the bracket 23 fixed on the movable frame 5, thus connecting the needles 16 of the cylinder 14 with the movable frame. Walking K01 shire works as follows. The movable frame 5 is in the initial position in which its bearing surface is located below the supporting surface of the fixed frame. Initially, the power cylinder 14 is switched on, the mechanism 14 is moved, the movable pajvia 5 moves under the products standing on the fixed frame. The power cylinders 6 of the lifting mechanism are then switched on. which, through the crankshafts 8 and the shafts 9, rotate the angular levers 10 and raise the movable frame 5, while the products are removed from the fixed frame. The subsequent activation of the cylinder 14 by the movable frame 5 is accompanied by horizontal movement and the product is moved over the next frame to the next position. Then the movable frame 5 is lowered to its original position. When the movable frame is raised and lowered, the guides 21 and 22 of the skull 23 slide along the slide blocks 20 of the lifting stabilization mechanism 18. The slide blocks 20 at the same time keep the movable frame 5 from possible horizontal movements. This ensures that the frame is raised and lowered vertically. The use of such conveyors reduces the production area occupied by the assembly and transportation of products, and also makes it easy to build them into in-line automatic lines with processing machines. Claims of the invention A walking conveyor comprising a stationary and a movable frame, a mechanism for lifting and moving a movable frame, characterized in that, in order to ensure precise positioning of the articles being moved, the conveyor is equipped with a stabilization mechanism for lifting the movable frame made in the form of a bracket mounted on the movable frame vertical guides and traverses with slider pivotally mounted on it placed in rails, the traverse being pivotally connected to the frame moving mechanism.
