Description

  In the present invention, a spill-proof flange is erected on both sides of the conveyance surface, and a horizontal beam is erected between both spill-proof flanges, and the object to be conveyed is within an area defined by both the spill-proof flange and the horizontal beam. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inclined conveyor belt that accommodates and conveys an object and a manufacturing method thereof.

Conventionally, a flexible spill-proof flange (also referred to as an ear cross) has been erected on both sides of the conveyor surface of the belt body, and a belt for an inclined conveyor that has a horizontal cross between the spill-proof flanges has been driven. There is an inclined conveyor that is wound around pulleys, driven pulleys, guide pulleys, and the like so that the object to be conveyed such as earth and sand can be stably conveyed without spilling even in a steeply inclined portion (for example, , See Patent Document 1).
JP-A-1-162616

  However, in the conventional inclined conveyor belt as described above, the horizontal beam is formed in a plate shape, and the lower end thereof is only fixed to the conveying surface of the belt body. When this occurs, the horizontal beam and the fixing portion of the belt main body to which the horizontal beam is fixed are deformed, the horizontal beam is brought down, and the conveyed object may spill out in the longitudinal direction of the belt main body.

  In order to eliminate such a risk, as shown in FIGS. 6 and 7, the cross rail (14) is projected on both sides of the base of the plate-like main body (15) in the longitudinal direction of the belt main body (1 a). A reinforcing base part (16) is provided, and the entire lower surface of the cross rail (14) including the base part (16) is used as a conveying surface of the belt body (1a) in the belt (1) for the inclined conveyor. It is conceivable that they are fixed so as to be sandwiched between a pair of wavy spill-proof flanges (13) and (13) standing on both sides thereof. (13a) is a band-shaped base provided at the base end of each anti-spill flange (13), and each anti-spill flange (13) is secured to the belt body (1a) with this base (13a). Has been.

  However, when this is done, as shown in FIG. 7, the corners of both ends of the base portion (16) projecting on both sides of the main body (15) of the cross rail (14) and the corrugated spill-proof flange (13) The base portion (13a) in (13) interferes with each other (see the circle (B) portion in FIG. 7), and the base portion (16) of the cross rail (14) or the base portion (13a) of the anti-spill flange (13) May not be sufficiently fixed to the belt main body (1a), and the cross rail (14) or the spill-proof flange (13) may be peeled off from the belt main body (1a).

  In view of the above-mentioned problems, the present invention can firmly fix the horizontal beam and the spill-proof flange to the belt body without interfering with each other, and the horizontal beam can be easily, quickly and inexpensively. An object of the present invention is to provide a belt for an inclined conveyor that can be manufactured and a manufacturing method thereof.

In the belt for an inclined conveyor configured to accommodate and convey an object to be conveyed in a space surrounded by the spill prevention flange and the horizontal beam, the horizontal beam is connected to the base of the plate-shaped main body and the belt main body. Reinforcing base portions projecting in the longitudinal direction are provided, and recessed portions that avoid interference with the anti-spill flange are provided at both ends of the base portion facing the anti-spill flange.

(2) In the above item (1), the recessed portion is a straight inclined surface inclined from both ends of the main body of the cross rail toward the center of the belt main body.

(3) In the above item (1), the recessed portion is a concave curved inclined surface inclined from both ends of the main body of the cross rail toward the center of the belt main body.

(4) In the above item (1), the indented portion is formed in a step shape by cutting out all the base portions near both ends of the main body of the cross rail.

(5) In the above item (1), the recessed portion has the same shape as the inner surface of the spill prevention flange, and the inner surface of the spill prevention flange is brought into close contact with the recessed portion.

(6) In the manufacturing method of the belt for an inclined conveyor, a long body provided with a base portion projecting from both sides is formed on the base of a vertical plate-shaped main body, and a wedge-like shape in plan view is formed on both sides of the long body. By inserting a blade, a recessed portion along the shape of the blade is formed in the base portion, and at the pointed portion of the recessed portion, the main body is cut to form a horizontal beam, and the lower end surface of the horizontal beam Is secured between spill-proof flanges provided on both sides of the conveying surface of the belt body.

According to the present invention, the following effects can be achieved.
According to the first aspect of the present invention, since the recessed portions for avoiding interference with the spill prevention flange are provided at both ends of the reinforcing base portion protruding from the base portion of the main body, the inner surface and the base portion of the spill prevention flange are provided.

  According to the second aspect of the present invention, it is possible to avoid the interference between the horizontal rail and the spill-proof flange by the linearly inclined surface, and it is possible to easily form the linearly inclined recess by the wedge-shaped cutter or the like. .

  According to the invention described in claim 3, the concave curved inclined surface makes it difficult for the spill-proof flange to interfere with the base portion, and the base portion extends over the entire length of the main body, so that the adhesive force to the belt main body is increased. And can have a beautiful appearance.

  According to the invention described in claim 6, the horizontal rail is continuously mass-produced by cutting the main body after inserting the wedge-shaped blade into the long body provided with the base portion on the plate-shaped main body. By attaching this to the conveying surface of the belt main body, the belt for the inclined conveyor can be manufactured easily, quickly and inexpensively.
