Air-cushion belt conveyer

专利摘要:
1506880 Air-cushion supported conveyer belts C O JONKERS 10 July 1975 [11 July 1974] 29144/75 Heading B8A A belt 3 supported on a cushion of air, e.g. as in Specification 1,341,897, is shaped preformed or differentially reinforced so as to remain closely spaced from its support surface 1. The belt may be thicker in the central region of its cross-section (Fig. 3, not shown), it may be preformed to an arcuate shape (when under no load and weightless conditions) (Fig. 2, not shown), and it may have reinforcements which are more densely spaced in the region of its cross-section (Fig. 4, not shown).

The invention relates to industrial transport, precise conveyors n · darling,
Famous belt conveyor hovercraft, 1 rectangular section! mi at the bottom, with a compressed-in |
namely, to the Lena air turning trough yii with holes connected to the air · ’, the tape attached to the bottom of £ 1].
The disadvantage of the conveyor is low productivity, since the tape has a small groove.
The closest in technical essence and the achieved result to the proposed phenomenon:
the proposed one is an air cushion conveyor belt, including a curved trough with holes in the lower part, a source of compressed from an elastic material, adjacent to the trough curvilinearly under the action of its mass ~
The disadvantage of · is that!
air connected tape
and. a conveyor in an unloaded gun or other shape, for example a trapezoidal with rounded edges. In the lower part of the gutter there are several holes 2, which are mainly located in its central part, and the number and size of these holes can be selected at a given value. Gutter G forms the upper wall of the chamber 3, having a lower wall 4, above which compressed air is supplied under a pressure of 10 °. The tape 5 adjoins the gutter curvilinearly under the action of its mass, while it has a concave shape with a curvature in a free state, the radius of which exceeds the radius of curvature of the gutter, and the distance from the lower part of the weightless unloaded tape to the line drawn through its edges, equal to 0.2-0.8 distance From the bottom of the tape to the line drawn through its edges when the location of the · tape in a concave groove · Air leaves the chamber 3 through the holes 2.
Air or other pressure medium exiting through the openings 2 slightly lifts the tape above the groove, thus eliminating mechanical contact between the tape and the groove and, therefore, wear of the tape. By ^{choosing the right} amount, size and location of holes 2, you can use the properties of the medium so that the tape even floated above the gutter without touching it.
The state of the belt is lifted by the compressed25.
The purpose of the invention is the reliability of the conveyor. This goal is achieved by the fact that in the conveyor belt on an air cushion containing a curved trough with holes connected to a source of compressed air, a tape of e.
, ala adjacent to:
LOSS OF COMPLIANCE
- increase in the lower part.
of elastic material with a curvilinear curvilinear40 but under the influence of its mass, the tape has a concave shape with a curvature in the unloaded weightless state, the radius of which exceeds the radius of the groove's radius, with the lower part of the tape: in the weightless state, the distance from the unloaded to the lines drawn through its edges is from ia from lower
0.2 to 0.8 distances: ty tape to the line, ι
The curved shape of the tape is achieved, for example, by making the tape from layers of rubber, fibers, etc. in curved form or using different shrinkage of the material of the upper and lower layers. The distance W of the curved tape in the unloaded condition should be more than 0.2 N, where N is the distance when the tape lies on the gutter and repeats its contour. Moreover, h is less than H so that the tape under the influence of its own weight and pressure of the medium easily repeats the contour of the trough. For this edge, when the tape is placed in the 50th, the tape should be very flexible
I shows a conveyor for cross section;

In FIG.
the air cushion of FIG. 2 - the belt is in the weight state, ι The air conveyor includes a metal trough 1 having a cross-sectional shape ok As shown in FIG. 1, the idle branch of the tape can be guided by ordinary rollers 6 located below the chamber 3. The tape is flexible enough to assume a flat position on such rollers.
This embodiment increases the reliability of the conveyor.
