Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor belt, and more particularly to a heat resistant non-adhesive conveyor belt for a belt conveyor used to continuously convey food materials to a drying oven. is there.

[0002]

2. Description of the Related Art Conventionally, in the case of mass-producing various foods, confectioneries, etc., when it is necessary to heat and dry the prepared and molded raw materials, this is used as a conveyor belt of a belt conveyor. It is common practice to place them on top of each other and continuously convey the belt conveyor into a drying oven or the like. Further, in this case, when the raw material is, for example, a cookie, a biscuit, a bread, or the like, the prepared and molded raw material has an adhesive property, so that it is on the surface of the conveyor belt of the belt conveyor. To prevent sticking as much as possible, non-stick conveyor belts with heat resistance are used.

A non-adhesive conveyor belt having such heat resistance has heat resistance obtained by weaving warp and weft yarns made of glass fiber as a base material. A woven glass fiber cloth, on each surface of which a fluororesin layer having heat resistance and non-adhesiveness is formed, is generally used.

[0004]

However, a non-adhesive conveyor belt constituted by forming a fluororesin coating layer on each surface of a heat resistant glass fiber woven fabric as such a substrate is excellent. Although it exhibits non-adhesiveness and heat resistance, on the other hand, due to the non-adhesiveness of the fluororesin and the fact that the surface of the conveyor belt itself is smooth, the articles to be conveyed arranged on this surface , For example, the coefficient of friction with respect to the food material to be treated, etc. is very small.Therefore, a belt conveyor using this conveyor belt stabilizes the food material, etc. to be treated along a substantially horizontal transport path. It can be transported, but if the conveyor path of the belt conveyor includes an inclined portion, the article to be conveyed has the surface of the conveyor belt in the inclined conveyor path portion. Et slipping phenomenon occurs, because this has a problem say can not be conveyed along the inclined transporting path to be processed article.

That is, the food materials such as the cookies exemplified above still show some adhesiveness to the conveying surface of the conveyor belt before being subjected to heat drying and the like. Even if it is possible to convey along a certain degree of inclined conveyance path, its adhesiveness is completely lost after heating and drying. The article slips off the surface of the conveyor belt,
There is a problem that it cannot be transported.

Therefore, the present invention solves the above-mentioned problems in the conventionally known non-adhesive conveyor belt, and has the excellent non-adhesiveness and heat resistance that it has, and is applicable to inclined conveyance. The problem to be solved is to obtain a non-sticky conveyor belt that can be used.

[0007]

In order to solve this problem, the present invention provides a non-adhesive conveyor belt comprising a heat-resistant woven fabric and a fluororesin coating layer formed on the surface thereof. It is characterized in that a large number of convex portions extending in the width direction of the heat-resistant woven fabric are formed at appropriate intervals in the longitudinal direction of the surface on the side that comes into contact with the treated food material. The convex portion is, for example, the number of weft yarns of a glass fiber woven fabric formed by weaving warp yarns and weft yarns made of glass fibers constituting the base material,
Alternatively, it can be formed by increasing or increasing the thickness of the convex portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A non-adhesive conveyor belt capable of inclined conveyance according to the present invention will be described below in detail with reference to the accompanying drawings showing an embodiment thereof. 1 shows a longitudinal cross-sectional view of one embodiment of the present invention. A conveyor belt 10 according to this embodiment has a warp yarn 1 and a warp yarn 1 made of glass fiber as its heat resistant base material. It is the same as the conventional one that the fluororesin coating layers 5 ₁ and 5 ₂ are formed on each surface of the heat-resistant glass woven fabric 3 formed by weaving the weft yarns 2, In the conveyor belt 10 according to this embodiment, the weft yarn 2 made of the glass fibers constituting the heat-resistant glass fiber woven fabric 3 has the longitudinal direction of the woven fabric 3 on one surface of the woven fabric 3. The three weft threads 2 ₁ are closely arranged as a group in the width direction with a constant space d therebetween. In this way, the number of the weft threads 3 is increased, for example, by using three weft threads 2 ₁ at a certain distance d in the longitudinal direction of the woven fabric 3 to increase the number of the weft threads 3.
A large number of protrusions 6 are formed on one surface of the woven fabric 3 at intervals d so as to project in the width direction of the woven fabric 3.

As described above, the conveyor belt 10 according to the present invention according to this embodiment has a large number of convex portions 6 on the surface thereof at regular intervals d in the longitudinal direction thereof in the width direction of the conveyor belt 10. Since it is arranged, this distance d
Is set to be slightly larger than the size of the food material or the like that is the article to be transported, the article to be transported is restrained on the surface of the conveyor belt 10 between the adjacent convex portions 6, and Although it is conveyed along with the movement, even if the conveyor path of the conveyor belt 10 includes an inclined portion, the article 6 to be conveyed is prevented from slipping on the surface of the conveyor belt 10 by the convex portion 6, so that the inclined portion is removed. The conveyor belt 10 enables reliable conveyance.

Next, FIG. 2 shows another embodiment of the conveyor belt according to the present invention, in which the conveyor belt 20 according to this embodiment is made of glass fiber as its heat resistant base material. Fluororesin coating layers 5 ₁ and 5 ₂ are formed on each surface of the heat-resistant glass woven fabric 3 formed by weaving the yarn 1 and the weft yarn 2, and the woven fabric 3
The fact that a large number of convex portions 6 are formed in the width direction of the conveyor belt 20 at regular intervals in the longitudinal direction is the same as in the case of the first embodiment 10, but the conveyor belt 20 according to the present embodiment.
In the case of, the convex portions 6 are formed by using the weft thread 2 made of glass fiber by using the thicker weft thread 2 ₂ at the location of the convex section 6. It differs from that according to one embodiment. However, it goes without saying that the conveyor belt 20 according to this embodiment performs exactly the same operation as the conveyor belt 10 according to the first embodiment.

Although two embodiments of the non-adhesive conveyor belt according to the present invention have been described above, in the conveyor belts 10 and 20, the convex portions 6 are formed on the heat resistant glass fiber woven fabric 3. The number and thickness of the weft threads 2 ₁ and 2 ₂ can be arbitrarily selected as needed, and the intervals d do not necessarily have to be equal intervals. Depending on the case, the intervals may be unequal. Further, the non-adhesive conveyor belt according to the present invention is not limited to the transportation of food materials and the like, but can be used for other general articles to be transported.

In the above description, a heat-resistant glass fiber woven fabric is used as the heat-resistant woven fabric. However, as the heat-resistant woven fabric, instead of such a heat-resistant glass fiber woven fabric, It goes without saying that a heat-resistant woven fabric obtained by weaving warp yarns and weft yarns made of aromatic polyamide fibers or the like may be used.

[0013]

Since the conveyor belt according to the present invention has the above-mentioned structure, its surface is non-adhesive, which is the same as the conventional one. However, in the present invention, Since a large number of convex portions are provided in the width direction at the necessary intervals in the longitudinal direction, it is possible to reliably convey the article to be conveyed even along the inclined conveyance path, and therefore,
When used as a conveyor belt in an equipment that continuously conveys an article to be conveyed having adhesiveness, for example, a food material, etc. by a belt conveyor along a conveyance path that includes an inclined portion, ensure that the article to be conveyed is It can be transported.
