Abstract

PURPOSE:To obtain a conveyer suitable for conveyance in a steep slope, by forming a part of prescribed area in an upper side material of a main unit belt at a prescribed distance, separating or cutting to raise said part of prescribed area and forming a cross frame. CONSTITUTION:Cross frames 6 are formed on the upper surface of a belt main unit 2 of a conveyer belt by separating or cutting to raise a part 5 of prescribed area at prescribed distance except a one side 6a. In this constitution, as compared with those as conventionally adhesively with the cross frame 6 to belt main unit 2, the cross frame 6 can increase its strength and is never exfoliated, further labor hours for adhesively attaching the cross frame 6 to the belt main unit 2 can be eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveyor belt, particularly a conveyor belt suitable for steep slope conveyance.

A conventional conveyor belt of this type has T as shown in Figure 1.
The cross-section 1 having a cross-sectional shape of the same shape is formed by molding and vulcanization separately from the belt suspension 2, and the horizontal beam 1 which is in contact with and glued to the entire belt suspension 2 is shown in FIG. 7 or 8. A belt fixing member 4 is used, which is fixed to a corrugated selvage 3 provided along both side edges of the belt break 20 using a connecting member 4 or the like.

However, when the conveyor belt is driven, it is stretched over a casing such as a bully and runs, so it is bent and a large shearing force acts, and the horizontal crosspiece 1, which is glued with a natural vulcanizing agent, etc. The conveyor belt's short lifespan has been a bottleneck, as it often peels off and interferes with conveyance on steep slopes.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an easy-to-manufacture conveyor belt truck that eliminates the disadvantages of conventional conveyor belts as described above and significantly increases the service life of the rungs.

The characteristic feature of the conveyor belt of the invention is that it has horizontal bars formed by peeling or cutting out portions of a predetermined area spaced at a predetermined interval from the upper material of the non-stop belt, leaving the upper side in the middle direction. 1. With this structure, the horizontal crosspiece is not in constant contact with the belt as in the past, but is formed integrally with the belt body, so it is strong and does not peel off. Instead, the conventional method of bonding the horizontal crosspieces to the belt main body can be omitted, resulting in an advantage that the conveyor belt can be manufactured easily and at low cost.

Preferred embodiments of the invention will be described below with reference to the drawings.

In the conveyor belt according to the invention shown in FIG. 2, horizontal bars 6 are formed by peeling or cutting out portions 5 of a predetermined area on the upper side 6a' at predetermined intervals on the upper surface of the belt main body 2.

In order to easily peel off or cut out the horizontal beam 6 shown in FIG. A non-adhesive member 7 such as a thin iron plate or a thin iron plate is placed at a predetermined depth at a predetermined area portion 5 of the upper blade bar rubber 2a of the belt 2 consisting of ll to facilitate peeling.
Indicates that the area is buried.

This seven iron plate 7 has a bent edge 7 that is bent upward on one side edge in the width direction of the side to be peeled to facilitate peeling.
You may form a. These seven iron plates 7 are removed after the horizontal rail 6 is raised.

However, it is advantageous to use a thin iron plate 7 to improve peeling and to bury a reinforcing canvas to reinforce the horizontal beam 6 when it is raised up.

FIG. 4 shows a modified embodiment of FIG. In the case shown in Fig. 2, a recess remains in the belt body 2 after the horizontal crosspiece 6 is raised, and there is a risk that transported objects may accumulate and become tough while the conveyor belt is in use. Place horizontal bar 6
The upper surface of the belt 6' is formed so that the upper surface of the belt is also raised, and the upper surface of the belt is made flat after the horizontal beam 6' is raised.

By flattening the upper surface of the belt after raising the horizontal crosspiece 6' in this manner, an advantage is obtained in that the adhesion of transported objects is reduced.

The relationship between the direction in which the horizontal bars 6 or 6' are raised and the direction in which the belt travels changes depending on transportation conditions.

The horizontal crosspiece 6 or 61 after being raised from the belt has corrugated selvedges 3 on both sides as shown in FIG. 7 or 8 as in the conventional case.
can be fixed to.

FIG. 5 shows a rubber 8 embedded and fixed in the base of the horizontal bar 6 shown in FIG. 2, and the horizontal bar 6 is held in an upright position.

The comb 8 is fixed in place by vulcanization 1. In Fig. 6, in place of the rubber 8 shown in Fig. 5, vulcanized rubber 9 with vulcanized rubber or reinforcing canvas embedded over the upper surface of the horizontal beam 6 and the belt is shown. The horizontal beam 6 is fully supported by adhesive.

The horizontal beams 6 shown in FIGS. 5 and 6 can be used without being fixed to the corrugated selvedges 3 on both sides, and can be used to prevent objects from adhering to the containers and clogging them, as well as to provide a reinforcing effect. By doing so, the stress concentrated at the base of the horizontal beam 6 can be relaxed and the durability life can be increased.
