Description

AT 395 240 B

The invention provides a device for conveying and sorting goods with a plurality of slides, which are movable along a certain path on a guide rail consisting of angle iron and are at least partially equipped with independent motor devices, which slides also ^ for conveying and unloading the Have goods, and have free running wheels and at least one pair of drive wheels for running along the 5 guide rail.

In this way, the fastened part of the device can be constructed more easily and simply, so that it only consists of a simple slideway or rail on which the slides run. The system can thus be more easily adapted to the various application needs, both from the arrangement - since the path can be changed very easily - and from the capacity point of view - since the number of conveyor slides can be changed as desired 10 without any intervention in relation to other parts of the destruction would be necessary - be adapted.

Sorting machines are already known in which goods are placed on conveyor levels, which move along a certain path, which has a number of collection points, at which the goods are correspondingly "encrypted at the time of loading by means of pushing devices or by tilting the conveyor level or by means of other systems be unloaded. 15 In all these known devices, the carriages are attached to loose wheels, the movement being exerted by one or more fixed motors which actuate pulling devices, such as chains, etc., which are attached to the carriages. This solution is particularly applicable to simple, for example, grading or fairly short paths.

However, if the path has curves, branches, inclined sections or sections of different heights 20, complications arise. It is then necessary to divide the path into a plurality of sections and to establish a suitable connection between one section and the following section, which leads to the device becoming bulky, heavy and expensive and, moreover, careful maintenance is necessary.

Furthermore, the entire facility often has to be restructured when changes in the route are required. The object of the invention is to avoid these disadvantages existing in the prior art.

This object is achieved in a device of the type mentioned at the outset in that the angular ice "i is L-shaped, in each case one leg being designed for running the wheels on both sides of the slide".

In this way, pulling devices can be saved, maintenance work reduced and, due to the simple structure of the system, immediate intervention can be made if any changes are necessary.

The invention will now be described in detail on the basis of a non-restrictive exemplary embodiment which refers to the accompanying drawings.

In the drawings shows:

Figure 1 is a plan view of a carriage in the device according to the invention. 2 shows a vertical section 35 through a device according to the invention; 3 shows a vertical section through the device from FIG. 2 along a plane running at right angles to the previously selected plane.

In the device according to the invention, the path is formed by a guide rail (1) which consists of a pair of angle irons (2) which are attached to a base (3) at a certain distance from one another, in such a way that their flanges ( 4) stand out. 40 The slide (5) run along the guide rail (1). Each carriage has a frame (6) on which pairs of shafts (7) are attached, which carry as many loose wheels (8). These wheels (8) carry the slide and act on the flanges (4) of the guide rails from opposite sides. A pair of shafts (9) is also attached to the frame (6), at the ends of which there are loose wheels (10) which run between the angle irons (2). 45 When using self-propelled sledges (as shown in the figures) on the frame (6)

Electric motor (11) attached, which drives a gear pair (13) via a reduction (12), which is keyed onto the shafts (14). Drive wheels (15) are also attached to these shafts and, like the wheels already mentioned, act on one of the flanges (4) from opposite sides. When using drawn carriages, the wheels (15) would of course be replaced by as many loose wheels (8). 50 The motor (11) is fed via sliding contacts (16) from loading brackets (17) running parallel to the guide rail (1). Above the frame (6) there is a conveyor plane (18) of a known type, for example a tiltable plate or a fixed plane on which a sliding element runs, or a rotating belt which is also driven by an independent motor, which is also via sliding contacts is fed by loading brackets. 55 The head parts of the sled are connected to upward-facing walls (19) made of elastic material, which fill the gap between two successive sleds to ensure the continuity of the levels to be occupied by the objects and to prevent these objects from falling into the free space. -2-

Claims (5)

AT395 240 B Articulated couplings (20) are also provided between the slides. In the operating state, the interconnected slides run along the guide rail (1) and convey the goods to be sorted. It is a feature of the invention that the motor devices are attached to the carriages so that the fixed part of the system is reduced to the guide rail, so that fixed motors and pulling devices for the carriages can be saved. The movable part of the device is thus independent of the fixed part, so that each unit can be changed as desired without affecting the entire system. Accordingly, the path can be changed either by deflecting the rail (1) as appropriate or by adding branches and increasing or reducing the length of the rail without it being necessary to act on the moving parts. Furthermore, the number of carriages can be increased or decreased in accordance with the required capacity of the system without any interference with the path. This results in a maximum flexibility of the entire device, whereby it is also possible to achieve agreement with the needs of the different companies in the shortest possible time and without particular difficulties. The structure of the device also becomes lighter, simpler, and less expensive, and maintenance is also reduced. The person skilled in the art could thus apply many changes and variants, but all of them are within the scope of the invention. PATENT CLAIMS 1.
