Abstract

A conveyor incorporates a conveyor belt (1), which is driven and guided in a track on a beam (3). The guiding of the belt (1) on the beam (3) is accomplished by means of flanges projecting laterally inwards against the conveyor belt (1) from both sides of the beam (3), which flanges engage in the conveyor belt (1). At the deflection positions, where the belt (1) leaves the beam (3) and is guided by a driven or non-driven wheel (4), in addition to the wheel (4) there is arranged an additional guiding device (6), which engages in the belt (1). <IMAGE>

Description

SPECIFICATION A conveyor The present invention refers to a conveyor of the type which incorporates a conveyor belt or chain arranged to be driven and guided in a track on a beam and via deflection or sprocket wheels.
Conveyors of this type are earlier known in different embodiments. An example thereof is shown in Swedish patent 375.961. The conveyor according to this patent incorporates a track assembled from U-shaped beams and the conveyor belt consists of supporting plates interconnected by means of a rope, whereby the plates move above the beam in the forward direction and below it in the return direction. The supporting plates can, however, also be interconnected by means of a so-called universal joint and they may be provided with projections intended to cooperate with a driving gearwheel or the like. The beam can extend horizontally as well as vertically. The main component of the conveyor track, the supporting beam, is normally extruded and the length of the desired sections is obtained by cutting the initial profile.At the ends of the beams are arranged driven or non-driven deflection a sprocket wheels for the conveyor belt.
A conveyor belt in these constructions is always pulled in a forward direction on the track by means of a driving device. Behind the driving device, which is ordinarily arranged at the return portion of the conveyor belt, is arranged a socalled slack, which means that the belt hangs loosely without essential guiding. This slack is necessary for joining the belt.
As the conveyor belt in some sections can be arranged vertically and as the friction between the belt and the base is very low, it is however possible that the slack may arise in the lower end of a vertical section, where the belt is not guided by the beam any longer but is intended to roll over a deflection wheel. This is not a desired phenomenon. Due to the slack it is also impossible to give the conveyor belt an alternating direction of movement.
The above problem has been solved by means of the present invention and it provides a conveyor, which incorporates a conveyor belt arranged to be driven and guided in a track on a beam, whereby the guiding on the beam is accomplished by means of flanges projecting inwards against the conveyor belt from both sides of the beam, which flanges engage in the conveyor belt, wherein at the deflection positions on the conveyor, where the belt leaves the beam and is guided by a driven or a non-driven wheel, an additional guiding device in addition to the wheel is arranged to engage in the conveyor belt. The additional guiding device may be stationary flanges which project laterally inwards against the belt and engage in this. Preferably these flanges have a thickness which is less than that of the flanges of the beams.
The flanges, which can be of plastics material with low friction, preferably are cast in one piece with the bearing seats for the bearings, which support the associated wheel, in order to obtain a simple design at the deflection position.
Embodiments of the invention will now be described by way of example, reference being made to the accompanying drawings, of which: Figure 1 shows a deflection wheel with associated conveyor belt as seen in section from the side; Figure 2 shows a section through the deflection wheel and the conveyor belt; and Figure 3 shows a driving station for the conveyor belt seen in a section from the side.
Figure 1 shows a conveyor belt 1 consisting of supporting plates 2 interconnected by means of universal joints as shown in the drawing. The conveyor belt 1 leaves the beam or track structure 3 at the end thereof and is thereupon guided by the supporting plates 2 engaging the deflection or sprocket wheel 4. If the conveyor belt in the present case now should extend vertically, then the conveyor belt 1 due to the gravity could hang down from the deflection wheel 4. Problems would then arise when the plates 2 again enter the beam 3 at its end 5. According to the invention there is however, besides the guiding accomplished by the deflection wheel 4, arranged an additional guiding by flanges 6 which extend co-axial with the deflection wheel 4.
Figure 2 shows how the flanges 6 are arranged. These flanges extend inwards from the side plates 7 and engage in the supporting plates 2 between their upper part 8 and their projection 9. The side plates 7 can at their central part be designed as a bearing seat 10 for the bearings 11, which support the shaft 12 and the deflection wheel 4. This deflection wheel 4 can be provided with a gearwheel or the like 13 in order to be able to act as a driving station for the conveyor belt.
The driving station which is shown in Figure 3, incorporates a driving wheel 14 which drives the belt 1. As can be seen from the Figure, the supporting plates 2 are guided by a device 15, which incorporates flanges 6 according to Figures 1 and 2. In this manner the conveyor belt 1 is forced onto the beam 3 without having any slack between the beam and the driving station. After the driving station there is, in this case, obtained a pushing force instead of a pulling force. Joining of the belt 1 and tightening thereof must then take place at a particular module on the conveyof. With the driving station of this type the conveyor belt can be driven reciprocally in desired direction.
With the conveyor according to the present invention the problems which have been present with known conveyors have been solved in a simple manner and there is obtained a secure guiding of the conveyor belt and a possibility of choosing the direction of movement of the conveyor belt.
A further advantage with the present invention is that the guiding of the conveyor belt takes place from the side or from the lower side whereby holdons or retainers of optional shape can be arranged on the upper side.

Claims (6)

1. A conveyor incorporating a conveyor belt arranged to be driven and guided in a track on a beam, whereby the guiding on the beam is accomplished by means of flanges projecting inwards against the conveyor belt from both sides of the beam, which flanges engage in the conveyor belt wherein at the deflection positions on the conveyor, where the belt leaves the beam and is guided by a driven or non-driven wheel, an additional guiding device in addition to the wheel is arranged to engage in the conveyor belt.
2. A conveyor according to Claim 1, wherein the additional guiding device consists of stationary flanges, which project laterally inwards against the belt and engage in the belt.
3. A conveyor according to Claim 1, wherein the thickness of the stationary flanges is less than that of the flanges projecting inwards against the belt from the beams.
4. A conveyor according to Claims 1-3, wherein the stationary flanges are made in one piece with the bearing seat for the bearings which support the associated wheel.
5. A conveyor comprising an endless conveyor chain and a track structure including two flanges extending along the path of travel of the chain and projecting towards one another transversely of the path of travel, which flanges engage and guide the chain, wherein at a location where the chain is engaged by a sprocket wheel and is not supported and guided by the track structure, means is provided which engages and guides the chain.
6. A conveyor substantially as herein described with reference to and as shown in the accompanying drawings.
