Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveyor that includes at least one driven seamless belt that travels in a generally horizontal path defined by a support frame. Conventional conveyors of the type having oppositely positioned sections supported at a number of spaced apart locations by a support structure, while still operating satisfactorily, have remained largely rigid until now. There is still room for improvement in reducing material costs by using chains that are smaller or larger than those used in the prior art. There is a need to provide something that retains the principle of pitchless construction, ie without the need for regularities in the distance between successive support structures.

It is an object of the present invention to provide a conveyor that improves on the foregoing.

The present invention provides a conveyor including at least one driven endless belt adapted to travel with upper and lower stroke sections in a generally horizontal path defined by frames mounted at spaced locations on a support structure. , the frame includes opposed sections, each of the cough sections having a substantially vertically extending central portion and upper and lower flanges, the upper flange being connected to the belt or the belt. It is an object of the present invention to provide a conveyor which is adapted to support an upper travel section, the lower flange being clamped to the support structure.

Preferably, the clamping of the profile to each support structure is carried out by means of two overlapping clamping blocks secured to the support structure by at least one bolt.

Similarly, each support structure has opposing open ends and U
It is preferred to provide a set of U-shaped sections whose lower sections are interconnected by horizontally extending strips welded to the sections. An internally threaded hole may be formed in the U-shaped part of each support structure to cooperate with a bolt for securing the support of the track guide member and/or the holder of the support leg.

The downward clamping block may be provided with an inverted U-shaped section, with legs located on either side of the horizontal strip of the support structure.

Each profile may be of the trough type, with the lower flange of each trough profile forming an angle of 90° or more with respect to the center of the cough profile to improve dehumidification from the conveyor support frame. is desirable.

Other features and advantages of the invention will be explained in detail below with reference to the accompanying drawings, which show examples of embodiments.

The conveyor of the present invention includes a number of driven endless belts traveling in a substantially horizontal path on a support frame 2. The conveyor according to the invention differs from those of the prior art in the structure of the support frame 2 and in the form of the support structure 3, which will be explained in more detail below.

As shown in FIG. 1, each belt 1 has a support frame 2. As shown in FIG. The frame is formed by two symmetrically positioned trumpet sections 4 spaced apart in opposite directions. Each profile 4 is provided with a relatively long central portion or body 5 and a short projecting flange 6. The body 5 is positioned in a vertical plane, and the lower flange 6 makes an angle with it of more than 90°. The diverging lower flange 6 is attached to the support structure 3
It is tightened to the base 7 provided with.

As is clear from FIG. 4, each base 7 is composed of two opposing protruding U-shaped parts 8. In the lower area of the base the U-shaped part has two horizontal strips 9 welded to it.
interconnected by. The work of tightening the two cone-shaped sections 4 to the base 7 is carried out using two overlapping block-type clamps 10 and 1 fixed to the base 7 by bolts 12.
1. The lower clamp 11 has an inverted U-shaped cross-section (see FIG. 4), the legs of which rest on either side of the horizontal strip 9 of the base 7.

Both protrusions 8 of each base 7 are provided with two internally tapered holes 13. The bore 13 cooperates with a bolt 23 for fastening the support 14 for the track guide 15 and/or the holder 16 for the leg 17 (see FIG. 1). Clamp 10
and 11 have approximately complementary shapes at the location of the lower flange 6 of the thorn profile 4. The bolt 12 may be provided with a hexagonal part 18 which can engage with a correspondingly shaped hole in the upper clamp 10. Bolts 12 extend between horizontal strips 9 and are secured by intermediate plates 19 and nuts 20. The top surface of the clamp 10 has a shape that approximately corresponds to the return stroke portion of the seamless belt 1 traveling thereon. In this connection, a groove or recess 21 is provided in which a plastic strip can be placed to reduce friction and wear on the belt 1.

FIG. 1 shows two different types of track guide member 15. On the right side of this figure, the simplest embodiment of the track guide element is shown, which can be fixed to the support 14 by means of a handle 22; on the left, it can also be fixed to the support body 14 via the handle 22;
Figure 3 shows a track guide member with adjustable height.

The conveyor of the embodiment of FIGS. 1-3 has 21 belts 1 parallel to each other, whereas the conveyor of the alternative embodiment of FIG. 4 has a single belt 1. Naturally, the invention is not limited to the embodiment described above, but conveyors using three or more substantially mutually parallel endless belts are likewise possible. The most important feature of the conveyor of the present invention is that since the support frame can be constructed as a structure, there is no need to drill holes for fixing bolts, and There is a large degree of freedom in determining the distance between By using a structure with a U-shaped part 8 and a strip 9 of the base 7, a conveyor with a twist-free structure is possible.
