Description

PLATE CONVEYOR

The invention relates to a plate conveyor belt having the features of the introductory part of claim 1.

Such plate conveyor belts are used for moving walks.

The use of conveyors, such as conveyor belts and

Escalators, has been known from department stores in London and New York since around 1900. Right from the start, the drive for this conveying means comprised at least one gearwheel which is driven by a gear and engages in chain links. Connected to the chain links are flat conveying elements or step elements of the conveying means, which are circulated in an endless loop. On the conveyor elements or the

Stair elements are e.g. People, packages, suitcases, etc. over a horizontal distance and, if necessary, up or down

transported. Examples of such means of transport and their drives are shown in DE 2 252 134 A1, WO 03/066500 A1, EP 0 013 793 A1 and DE 1 456 375 A1.

Moving walks and escalators are known which not only run over straight stretches, but also those which lead around curves, that is to say have curve sections.

It is also possible that moving walks not only in horizontal planes, but also uphill or downhill, with curved

Transitions between ascending or descending sections and horizontal planes lead. Even with escalators, there is a transition between a rising or falling

Transport level to a horizontal transport level. When a transport level is referred to in the following, both horizontal levels and rising or falling levels and their transitions to horizontal levels are understood. When moving walks, comprising slat conveyors, are manufactured, the length of the moving walk is determined by the actual length of the slat conveyor, which consists of the

interconnected slab conveyor elements, the length of the moving walk only in the, by the length of

Plate conveyor elements predetermined steps can be produced. The length of the rails on which the

Plate conveyor elements are guided, must then be adapted to the length of the plate conveyor belt, which always corresponds to a multiple of the length of an individual plate conveyor element.

It is problematic to adapt the length of the rails to the actual length of the plate conveyor belt, in particular if the plate conveyor belts have curves. Different

Curve radii and courses lead to the length of the rails deviating from the actual length of the plate conveyor belt, whereby this deviation must be compensated on site after the rails have been set up.

The invention is based on the object one for one

To provide moving walkway suitable plate conveyor belt of the type mentioned above, in which the length of the rails to the length of the plate conveyor belt in a simple manner

can be customized.

According to the invention, this object is achieved with a plate conveyor belt which has the features of claim 1.

Preferred and advantageous embodiments of the invention are the subject of the subclaims.

Since in the plate conveyor belt according to the invention between

Adjacent rail elements are provided with length compensation pieces, the length of the rails can be easily and easily adapted to the length of the plate conveyor belt. In one embodiment of the invention are

Length compensation pieces are provided which have edges that are obliquely aligned to the longitudinal extension of the rails of the rail elements, and that the ends of rail elements for the installation of length compensation pieces have edges which are also obliquely aligned to the longitudinal extension of the rails.

In a preferred embodiment of the invention, there are adjacent rail elements between the center rails, in particular rail elements, between which

Length compensation pieces are arranged, coupling pieces

intended. The cross-sectional shape of the coupling pieces corresponds to the cross-sectional shape of the center rails, which the

Guide the plate conveyor elements sideways.

In a practical embodiment of the invention, there are both a plurality of length compensation pieces and a plurality of coupling pieces for the center rails with different dimensions

(each in the form of a "set") so that the appropriate one from the set with length compensation pieces

Length compensation piece and / or the matching coupling piece can be selected from the set of coupling pieces.

In practice, the procedure here is to insert a coupling piece with the appropriate length between adjacent rail elements and then insert suitable length compensation pieces into the recesses. It is particularly advantageous if the length compensation piece has edges which are inclined to the longitudinal extension of the rails. In this embodiment, the length compensation pieces can simply be pushed so far into the cutouts that they bridge the rails of the rail elements connected to one another essentially without play. So is an exact one

Adjustment of the length of the rail system possible. In practice can be proceeded in such a way that initially a rough

Compensation is made by using the matching coupling piece and matching length compensation pieces and then fine-tuning the length compensation by further steps

Insertion of the length compensation pieces into the recesses between the rail elements is carried out.

Further details and features of the invention emerge from the following description of preferred exemplary embodiments with reference to the drawings. It shows:

In Fig. 1 a moving walkway 2 comprising a plate conveyor belt 1 is shown, which in a horizontal transport plane 3 in the embodiment shown around several curves 4 to 7, between which there are straight transport routes 8 to 11, leads. The plate conveyor belt 1 of the moving walkway 2 consists of a large number of approximately sickle-shaped plate conveyor elements 12, which are connected to one another so that they can move around curves 3 to 7 as well as along straight transport routes 8 to 11.

2 shows a preferred embodiment of a drive for a plate conveyor belt 1 according to the invention, but other drives can also be used within the scope of the invention. The shown drive of the plate conveyor belt 1 with

Plate conveyor elements 12 has drive units 13, which have externally toothed belts 14, which between pulleys, a driving pulley 15 and rollers of a

Pressure unit are guided. In addition, there is a

Tensioning device 16 is provided which engages one of the deflection rollers and is arranged on a mounting plate 17 together with the aforementioned components. The plate conveyor elements 12 each have one surface, one lower surface, two

Side surfaces 18 and an arm 19 with one on one

Middle rail 21 rolling guide piece 22 on.

To the drive power from the belt 14 to the

To transfer plate conveyor elements 12, a rack 23 is arranged on each of the side surfaces 18 of the plate conveyor elements 12. So that the belt 14 engaging in the rack 23 is better protected from dirt, objects on the

Plate conveyor elements 12 and is protected from inadvertent contact with people, the rack 23 is in a lateral step in the side surfaces 18 on the

Plate conveyor elements 12 arranged. The rack 23 is arranged in the side step so that the teeth of the

Rack 23 are set back from the side surfaces 18. In Fig. 2, the drive with two drive units 13 and the plate conveyor belt 1 is shown. The plate conveyor elements 12 are connected to one another, arranged one behind the other at a small distance, and are guided along rails 24. The

Rails 24 are components of rail elements 25, each rail element 25 having two outer rails 24 and the middle rail 21 between them. On a surface 26 of the outer rails 24, the plate conveyor elements 12 run with rollers 27 and the middle rail 21 serves to guide the plate conveyor elements 12 laterally by means of guide rollers of the guide pieces 22.

The rail elements 25 are connected to one another by form-fitting couplings 28. FIG. 3 shows in more detail how adjoining rail elements 25 are connected to one another with the form-fitting couplings 28.

Further rail elements 29 are provided for length compensation

(Compensating rail elements) are provided which are equipped at one end with the couplings 28 and at the other end have areas for receiving length compensating pieces 31 for the outer rails 24. When the rail elements 29 are connected to one another, these areas form recesses 32 into which the length compensation pieces 31 can be inserted. In addition to the length compensation pieces 31 between the outer rails 24 of adjoining rail elements 29, a coupling piece 33 is inserted between the middle rails 21. The

Coupling pieces 33 have extensions 34 at their ends, which in the installed state in recesses 35 at the ends of the

Engage middle rails 21. In addition, the middle rails 21 and the coupling pieces 33 have horizontally aligned slots 36 and tongues 37 at their ends facing each other, with which they engage in a comb-like manner and thus a

Form continuous guide for the guide pieces 22 (Fig. 12). As shown in Figures 5 and 6, there is a set of

Length compensation pieces 31 with different dimensions, as well as a set of coupling pieces 33 with

different lengths.

It is preferred that the length compensation pieces 31 have edges 38 which are oriented obliquely to the longitudinal extension of the rails 24 and are, for example, essentially triangular or trapezoidal. What is essential in this is preferred

Embodiment of the invention that the edges 38 are aligned in a V-shape to one another.

It is provided that the rail elements 29 adjoining one another between the ends of the rails 24 are provided

Recesses 32 have edges 39, which at the ends of the

Rails 24 are arranged and are inclined to the longitudinal extent of the rails 24. The inclination (alignment) of the edges 39 is identical to the inclination (alignment) of the inclined edges 38 of the length compensation pieces 31. Therefore, as shown in FIG. 3, the length compensation pieces 31 can rest continuously with their inclined (lateral) edges 38 on the edges 39 of the recesses 32.

For example, it can be provided that the edges 39 of the rails 24 are formed by strips 41, which for

Longitudinal extent of the rails 24 are aligned obliquely. The angles of the oblique alignment of the strips 41 correspond to the angles of the inclined edges 38 of the length compensation pieces 31, which lie against these strips 41 the rollers 27 on the

Transition area leads. In principle, it would also be possible within the scope of the invention to use length compensation pieces 31 with edges 38 that are not arranged in a V-shape but, for example, parallel, with the edges 39 of the recesses 32 or ends of the rails 24 being essentially aligned accordingly at an angle . In this embodiment of the invention, too, would be an im

Substantially jerk-free crossing of the transition between the rails 24 on length compensation pieces 38 is possible because the rollers 27 would run simultaneously on both the respective rail 24 and on the length compensation piece 38 due to the inclined position of the transition area. The disadvantage would be that a larger number of different widths

Length compensation pieces 38 would have to be kept ready so that the gaps between the rails 24 and length compensation pieces 38 do not become too large.

In the area of joints between adjoining

Rail elements 29 with length compensation are provided below the rail elements 29 two plates 42 which are connected to the ends of the rail elements 29, e.g. by screws or the like. , are connected. For a more stable connection between the ends of the outer rails 24 and the plates 42, transversely protruding strips 43 are additionally provided, as they are also to be connected directly to one another via the couplings 28

Rail elements 25, 29 are provided.

8 to 10 show how a length compensation piece 31 is used between adjoining rail elements 29, with screws 44 passing through elongated holes 45 in the

Length compensation pieces 31 are guided, are provided to fix the length compensation piece 31 in the correct position between the rail elements 29.

Figures 8 and 9 show an average distance between

adjoining rail elements 29, whereas FIG. 10 and 11 the largest and smallest distances "min" and

Show "max" between adjoining rail elements 29. FIG. 10 shows the shortest possible distance "min" between adjoining rail elements 29 and FIG. 11 shows the greatest possible distance "max" between adjoining ones

Rail elements 29, wherein in the case of FIG. 10 in the

Recess 32 a triangular length compensation piece 31 and, in the case of FIG. 11, a trapezoidal length compensation piece 31 is provided in the recess 32.

The rail elements 29 provided for length compensation can - cf. Fig. 4 - be provided with different lengths.

In practice, when adjusting the length of a straight

Transport route 8 to 11 of a moving walk 2, the one

having the plate conveyor belt 1 according to the invention, the procedure is such that the rail system formed by the rail elements 25 and 29 is in the desired shape of the moving walk 2

is produced, the number and shape of the curves and the total length of the chain of plate conveyor elements 12 must also be taken into account. For precise setting of the length of the

Rail system, which is formed by the rail elements 25 and 29, the length compensation pieces 31 are used. This is done first by selecting a suitable

Length compensation piece 31 from the set shown in Fig. 5 brought about a rough length compensation. Then one will

Fine adjustment carried out by the length compensation piece 31 - as shown by the double arrow 46 in Fig. 9 - in the triangular recesses 32 between adjacent

Rail elements 29 is inserted.

It is not a disadvantage if there is slight play between the central rails 21 of rail elements 29 and the coupling piece 33 (FIG. 6) inserted between the central rails 21 is present, since this is compensated for by the tongues 37 sliding in the slots 36.

In summary, an embodiment of the invention can be described as follows:

A plate conveyor belt 1 for moving walks 2 comprises one of

Rail elements 29 formed rail system with rails 24 and a guide for plate conveyor elements 12 of the

Plate conveyor belt 1 serving the middle rail 21. The length of the rail system is adjustable. For this purpose are between

adjoining rail elements 29 essentially triangular recesses 32 which are delimited by strips 41 are provided. Triangular or trapezoidal length compensation pieces 31 are inserted into the recesses 32 and pushed in so far that the inclined edges 38 of the

Length compensation pieces 31 rest against the edges 39 of the recesses 32 formed by the strips 41. The center rails 21 of adjacent rail elements 29 are connected to one another with coupling pieces 33.
