BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a conveyor belt comprising a plurality of link elements which are mutually coupled in pairs by means of a hinge, which hinge comprises at least one hinge pin present on the one link element and extending transversely of the longitudinal direction of the conveyor belt and a plurality of correspondingly registered eyes present on the other link element and engaging round said hinge pin(s) such that the conveyor belt is flexible in transverse direction relative to the main plane of the conveyor belt.
Such a Conveyor belt is known from FR-A-15 97 154. The known conveyor belt comprises link elements, all having a plurality of eyes located on opposite sides thereof, which link elements are mutually coupled in pairs by means of hinge pins extending in transverse direction of the conveyor belt through the eyes of neighbouring link elements.
Relative to this known art the conveyor belt according to the invention has the feature each link element comprises a least one slide block, in the end zones of which slide block are arranged continuous holes for passage of respective hinge pins, wherein the end zones of adjacent slide blocks are interwoven in the longitudinal direction of the associated hinge pin, which slide blocks are arranged to co-act with a slide strip forming part of a transporting device.
SUMMARY OF THE INVENTION
The conveyor belt according to the invention thus has at least one continuous row of slide blocks which can co-act with a slide strip forming part of a transporting device
Particularly in an embodiment intended for transporting products through a thermal treatment station, for instance a furnace or freezer area, the embodiment is recommended in which a slide block consists substantially of a material with a temperature resistance satisfying a chosen norm. A slide block can for instance consist of steel, for instance stainless steel.
A specific embodiment has the special feature that a slide block consists of a wear-resistant plastic.
A very suitable material in this respect is a nylon.
The invention is also very suitable for forming longitudinal partitions. For this purpose the conveyor belt can have the special feature that a slide block supports a plate extending transversely of the main plane of the conveyor belt.
The slide blocks can be connected to the rest of the conveyor belt with very simple mechanical means. A specific embodiment has the special feature that a block is coupled to a hinge pin by means of a key.
The most inexpensive and simple embodiment from the point of view of production technique is that in which all blocks are identical. Attention is drawn in this respect to the fact that the interwoven parts of the end zones of adjacent slide blocks can complement each other mirror-symmetrically. Protruding slide blocks can be located on one side or on mutually opposite sides. Obtained in this embodiment is the example for all cases that only one type of product has to be manufactured and held in stock for purposes of replacement.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will now be elucidated with reference to the annexed drawings of several random embodiments. Herein:
FIG. 1 shows a perspective view of a portion of the conveyor belt according to the invention;
FIG. 2 shows a part of the conveyor belt according to FIG. 1 on enlarged scale and partly in exploded view;
FIG. 3 shows a view corresponding with FIG. 2 of another embodiment; and
FIG. 4 shows a view corresponding with FIG. 1 of yet another embodiment.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 shows a transporting device 1 comprising drive wheels 2 which are drivable by means which are not shown and which co-act with a conveyor belt 3 according to the invention. Conveyor belt 3 comprises a plurality of link elements 4 which are mutually coupled in pairs by means of respective hinges. Each link element comprises a plurality of wires 5 bent into a loop shape at their ends, the loop-shaped end zones of which co-act with respective pivot shafts 7 (see
