Abstract

A conveyor with a suspension belt having a horizontally closed track containing racks with rolling guides fixed to them, which have flat sections for loading and unloading the conveyor, with the possibility of movement of suspensions along them, including elements of a connecting lock and paired with an endless conveyor belt forming a closed tray , using flexible intermediate elements, characterized in that on the part of the suspensions rotors are installed - secondary elements of a linear asynchronous motor (LAD) moving suspensions under the influence of a magnetic field generated by the stator - the primary element of LAD.

Description

The utility model relates to conveyor transport, namely, to conveyor belts with hanging tape, and can be used in all industries.

Known conveyor with a hanging belt [1], containing racks on which the rolling guides are mounted with the possibility of movement of suspensions pairwise connected in a plane perpendicular to the longitudinal axis of the conveyor by rigid intermediate elements to which an endless conveyor belt is attached, while on rigid intermediate elements rotors are installed - the secondary elements of a linear asynchronous motor (LAD), receiving movement under the action of a magnetic field generated by the stator - the primary element of the LAD.

The disadvantage of this conveyor is the difficulty of ensuring the calculated value of the air gap between the stator and the rotor LAD, due to displacements and vibrations of the tape due to the expected uneven distribution of cargo and dynamic loads arising during the movement.

Closest to the proposed technical solution is an overhead conveyor belt [2], comprising racks with rolling guides fixed to them, which have flat sections for loading and unloading the conveyor, with the possibility of movement of suspensions along them, which are interfaced with an endless conveyor belt forming a closed tray , with the help of flexible intermediate elements covering the tape over the entire width, while the conveyor has a horizontally closed path. The pendants are equipped with micro drives, clamping devices, elements of the connecting lock, current collectors with brushes.

The disadvantage of this conveyor is the complexity of the design, the significant mass of the drive suspensions of the tape, as well as the difficulty of synchronizing the movement of each pair of drive suspensions, located symmetrically to the longitudinal axis of the conveyor and connected by flexible intermediate elements with the tape.

The objective of the proposed utility model is the development of the design of the conveyor with a hanging tape with minimal material consumption, increased speed and reliability of hermetic transportation of cargo.

This task is achieved by the fact that the conveyor with the hanging tape has a horizontally-closed track, contains racks with rolling guides fixed to them, which have flat sections for loading and unloading the conveyor, with the possibility of movement of suspensions along them, including elements of a connecting lock and paired with an endless with a conveyor belt forming a closed tray, with the help of flexible intermediate elements, rotors are installed on the part of the suspensions - secondary elements of a linear asynchronous motor (LAD), moving suspensions under the influence of a magnetic field generated by the stator - the primary element of LAD.

When implementing the utility model, a technical result can be obtained consisting in the possibility of hermetically moving cargo along a horizontally-closed track of a spatial configuration of any length in the forward and reverse directions, in addition, in reducing the metal consumption and simplifying the design by eliminating the mechanical drive, as well as in reducing tape load.

Figure 1 shows a side view of the conveyor; figure 2 is the same, a top view; figure 3 shows a cross section of a branch of the conveyor (section aa in figure 1); figure 4 is the same (section bB in figure 1).

The conveyor with a hanging belt includes a supporting metal structure 1 (Figs. 1, 2, 3, and 4), with horizontal-closed rolling guides 2 mounted on it (Figs. 1, 2, 3, and 4), on which suspensions 3 are mounted (Fig. 1, 2, 3, and 4) with the possibility of their movement along the guides 2. An endlessly closed in the horizontal plane conveyor belt 4 (Figs. 1, 2, 3 and 4) is connected to the suspensions 3 using flexible intermediate elements 5 (Fig. 3 and 4). Stators 6 (Fig. 3) are the primary stationary elements of a linear induction motor (hereinafter referred to as LAD), which are a magnetic circuit with a winding receiving energy from the network, mounted on a supporting metal structure 1. Rotors 7 (Figs. 3 and 4) are secondary movable LAD elements ), which are made in the form of sheets (strips) of non-magnetic metal or complex packets of adjacent strips of non-magnetic and ferromagnetic metal, through an insulating gasket are fixed to parts of the suspensions 3, including elements of the connecting lock 8 (Fig. 3 and 4) . At the cargo transportation section, the tape 4. has the form of a closed trough, and at the loading and unloading sections, under which the roller batteries 9 are installed (Fig. 4), and the turning sections the tape is flattened.

The conveyor with a hanging tape works as follows. When voltage is applied to the stator windings 6 (FIG. 3), LAD flows an alternating current generating a traveling magnetic field, which, as a result of magnetic induction, interacts with the rotors 7 (FIGS. 3 and 4) of LAD and causes a longitudinal shear force moving the suspension 3 (FIG. .1, 2, 3, and 4) along the rolling guides 2 (Figs. 1, 2, 3, and 4). Suspension 3 through the intermediate elements 5 (figure 3 and 4) carry the tape 4 (figure 1, 2, 3 and 4) with the load. The elements of the connecting lock 8 (Figs. 3 and 4) of the suspensions 3 are fixed if the guides 2 come close and a working groove of the tape 4 is formed, or open if the guides diverge and the tape 4 is flattened. The guides 2 have such a configuration that the tape 4 passes the loading, unloading and turning sections in a flattened state. At the same time, on the turning section, to reduce the resistance to movement, the flattened tape rotates 90 degrees.

When implementing a utility model, a technical and economic result can be obtained consisting in the fact that the use of a linear induction motor allows to simplify the mechanical transmission of traction to the belt, increases the speed and reliability of the conveyor. The structural arrangement of the stator and rotor of the linear induction motor provides the calculated value of the air gap between them. A horizontally-closed conveyor route, the location of the flush loading and unloading sections at any point, and the rails converging on the working section where the suspensions are connected by lock elements, while the belt takes the form of a closed tray, which allows the simultaneous tight movement of several types of goods in direct and reverse direction, using for transportation the entire length of the track.
