Definitions

  • the present invention generally relates to conveyor belts and especially a foraminous conveyor belt, which comprises a plurality of link means, which are successive ⁇ sively connected in series and each of which has two transverse rods, which are spaced apart in the longitu ⁇ dinal direction of the conveyor belt and which at each lateral edge of the conveyor belt are fixedly intercon ⁇ nected by a link which connects the link means with the adjoining link means on the one hand pivotally about axes substantially in parallel with the transverse rods and, on the other hand, displaceably in the longitudinal direction of the conveyor belt.
  • Such a conveyor belt is disclosed in e.g. US-A- 5,190,143, in which the movability of the link means relative to each other is used to let the conveyor belt travel in a helical path as well as round guide rollers.
  • US-A-5, 190, 143 use is conventionally made of metal wires that are helical in a substantially flat ⁇ tened fashion, or zigzag wire spirals for providing a foraminous carrying surface of the conveyor belt.
  • the wire spiral When mounting such a known conveyor belt, the wire spiral must be passed onto two or more transverse rods, which is a relatively time-consuming operation.
  • the wire spirals form two layers of wires, i.e.
  • the object of the present invention therefore is to provide a conveyor belt of the type mentioned by way of introduction, which essentially eliminates the drawbacks of the prior-art conveyor belt with wire spirals.

  • each cantilever branch strut of the grating of the first type has a free end, which can enclose one of the transverse rods of the link means to such an extent that the grating is fixed.
  • the free end of the branch strut extends at least partially round the side of the transverse rod facing away from the other transverse rod of the link means.
  • each canti ⁇ lever branch strut is suitably so resilient that the grating of the first type is mountable by snap action over the two transverse rods of a link means.
  • the grating of the second type can either be such that each end of each slide strut is fixedly connected to the corresponding end of only one adjoining slide strut, or such that each end of each slide strut is fixedly con- nected to the corresponding end of both adjoining slide struts under the associated branch strut.
  • the grating of the second type is preferably made of a metal wire, which will then extend essentially in zigzag.
  • the grating of the second type is preferably made of injection-moulded plastic.
  • a large number of further different combinations of, for instance, plastic and metal may, however, be used for the manufacture of the gratings of the first and the second type.

  • Figs 2 and 3 are perspective views of a first embo- diment of a conveyor belt according to the present inven ⁇ tion;
  • Fig. 4 is a perspective view of a second embodiment of a conveyor belt according to the present invention.
  • Fig. 5 is a schematic top plan view of the conveyor belt in Fig. 4.
  • Fig. 6 is a perspective view of the conveyor belt in Fig. 4 in retracted or collapsed state.
  • Each link means 1 comprises two transverse rods 2, 3, which are spaced apart in the longitudinal direction of the conveyor belt and extend over the entire width of the conveyor belt. At each lateral edge of the conveyor belt, the transverse rods 2, 3 in each link means 1 are fixedly interconnected by a link 4.
  • Each link
  • each link means 1 is on the one hand pivotable relative to the adjoining link means about axes substan ⁇ tially in parallel with the transverse rods 2, 3 and, on the other hand, displaceable relative to the adjoining link means 1 in the longitudinal direction of the con ⁇ veyor belt.
  • This relative movability of the links is shown in the right part of Fig. 1.
  • the known conveyor belt has a carrying surface, which is formed of a wire netting in the form of zigzag metal wires 6, each enclos ⁇ ing the transverse rods 2, 3 of its associated link means 1, and zigzag wires 7 enclosing the transverse rod 2 of a link means 1 and the transverse rod 3 of the adjoining link means 1.
  • the carrying surface of the conveyor belt is formed of gratings of a first type 8 and gratings of a second type 9.

  • the grating of the first type 8 is more specifically fixable to the link means 1 by the free ends of the branch struts 11, 12 being adapted each to enclose one of the transverse rods 2, 3 of the link means 1 suf ⁇ ficiently to make it possible to achieve the desired fix- ing. More specifically, the free end of each branch strut 11, 12 extends partly round the side of the corresponding transverse rod 2, 3 which faces the other transverse rod 3, 2 of the link means 1.
  • the enclosure of the transverse rod 2, 3 is about 180°, and an enclosure of at least 90° is necessary for fixing to take place.

  • the grating of the second type 9 Before snapping on the grating of the first type 8 to the respective link means 1, a grating of the second type 9, however, should be arranged over each transverse rod 2, 3 of the link means 1 in question. More specifi ⁇ cally, the grating of the second type 9 consists of a plurality of slide struts 13 having two ends 14, 15. The slide struts 13 are arranged essentially in parallel with each other and extend substantially in the longitudinal direction of the conveyor belt. The ends 14, 15 of each slide strut 13 have a downwardly directed hook 16, 17 with an internal radius which substantially corresponds with the radius of the transverse rods 2, 3. The juxta ⁇ posed slide struts 13 are, at the outer end of the hooks 16, 17, fixedly interconnected by means of bridges 19. The mounting of the gratings of the first type 8 and the ⁇ econd type 9 on the link means 1 is illustrated in Fig. 3. As shown adjacent the left link means 1 in

Abstract

Ce transporteur à courroie comprend une pluralité d'articulations (1) qui sont successivement reliées en série et comportent chacune deux tiges (2, 3) transversales, lesquelles sont espacées l'une de l'autre dans le sens longitudinal du transporteur à courroie et sont, au niveau du bord latéral de cette courroie, reliées de manière fixe par une plaque (4) de liaison, laquelle relie chaque articulation à l'articulation voisine, d'une part, de manière pivotante autour d'axes essentiellement parallèles aux tiges transversales, et d'autre part, de manière mobile dans le sens longitudinal du transporteur à courroie. On a disposé entre les deux tiges (2, 3) transversales de chaque articulation (1) un treillis (8) d'un premier type comportant une barrette (10) de liaison, laquelle s'étend entre les tiges transversales dans le sens longitudinal de celles-ci et présente des barrettes consoles (11, 12) annexes qui sont disposées transversalement par rapport à la barrette de liaison, sont dirigées chacune vers la tige transversale associée et permettent la fixation du treillis sur les articulations. On a placé un treillis d'un second type (9) entre chaque paire de treillis voisins du premier type (8), le treillis du second type présentant une pluralité de barrettes (13) de coulissement pourvues de deux extrémités (14, 15) qui s'étendent chacune entre deux barrettes consoles (11, 12) contiguës du treillis voisin du premier type et sont reliées de manière fixe à une extrémité (14, 15) correspondante d'au moins une barrette de coulissement contiguë, sous la barrette console (11, 12) intermédiaire.
