  By the way, in the conventional belt 100, since the through hole 106 is formed in the belt main body 104 or the attachment 110 is fixed using the bolt 108, there is a problem that the belt configuration becomes complicated and the number of assembly steps increases.

  Further, in order to avoid interference with the head of the bolt 108, the pulley 102 must be provided with a notch 112, which complicates the configuration of the pulley 102 and requires man-hours for providing the notch 112. It will be.

  It should be noted that a bolt having a smaller head than that shown in FIG. 7 is used, a notch is provided in the tooth portion of the belt main body 104, and a head of the bolt is provided in the notch. Although it is not necessary to provide the notch 112, since it is necessary to provide a notch in the tooth portion of the belt main body 104, the configuration of the belt main body becomes complicated and the number of steps for manufacturing the belt increases.

  The above problem also occurs in a belt for conveying a belt conveyor in which a support body for placing and supporting an object as the attachment is installed on the belt main body.

  Therefore, when the support body is installed in the belt body portion, a method is provided in which a hole is formed in the belt body portion, and a part of the support body is inserted into the hole to thereby install the support body in the belt body portion. Can be considered.

  However, when the method is adopted, the belt main body is elastically deformed at the portion where the belt main body abuts on the pulley and bends in an arc shape, and the hole (the hole into which the support is inserted) widens, and the support There is a risk that the body will come off the belt body and come off.

  The present invention has been made in view of the above problems, and in a belt for conveying an object used in a belt conveyor, it has a simple configuration and a support body can be easily installed on a belt main body. An object of the present invention is to provide a belt for conveying an object which is difficult to be detached from the belt main body portion when the support is used, and a belt conveyor using the belt.

  According to the first aspect of the present invention, there is provided a belt for conveying an object used in a belt conveyor, wherein the belt main body and a plurality of support members provided upright at a thickened portion of the belt main body. A conveyor belt having

  According to a second aspect of the present invention, in the conveying belt according to the first aspect, the belt main body portion is a conveying belt formed integrally.

  According to a third aspect of the present invention, in the conveying belt according to the first or second aspect, the support is press-fitted into a hole provided in a portion where the base end side is thicker in the belt main body. The support body is a conveyor belt that is erected by being screwed into a hole provided in a portion where the base end side is thicker in the belt main body portion.

  A fourth aspect of the present invention is directed to the conveyance belt according to any one of the first to third aspects, a pulley around which the conveyance belt is wound, and a rotation driving unit that rotationally drives the pulley. A belt conveyor.

  According to the present invention, in the belt for conveying an object used in a belt conveyor, the support body can be easily installed on the belt main body portion with a simple configuration, and the support body is used when the belt main body is in use. There is an effect that it is difficult to come off from the part.

  FIG. 1 is a diagram showing a schematic configuration of a belt conveyor 1 according to an embodiment of the present invention, and FIG. 2 is an enlarged view of a portion II in FIG.

  The belt conveyor 1 is a device for conveying a thin plate-like object such as a glass substrate W for LCD, for example, and includes pulleys 3 and 5 (upstream pulley 3 and downstream pulley 5) and each of these pulleys. 3 and 5 a conveyor belt (a conveyor belt used in the belt conveyor 1) 7 and a rotation driving means 9 (for example, a motor) for rotationally driving the pulley (for example, the downstream pulley 5). Etc.).

The conveyor belt 7 includes a belt body 10 and a support 11 for supporting the glass substrate W to be conveyed in contact with the glass substrate W.
The belt body 10 is made of a rubber-based material such as urethane rubber or chloroprene rubber, and is formed in an annular shape with a predetermined width.

  Further, when the belt main body 10 is wound around the pulleys 3 and 5 formed in a columnar shape, the belt main body 10 is outside from the surface (outer surface) opposite to the surface in contact with the pulleys 3 and 5 (outside surface). The thick portions 13 and the thin portions 15 formed by increasing the thickness on the side away from the pulleys 3 and 5 are alternately formed in the longitudinal direction.

  The support 11 is made of a synthetic resin such as ultra high molecular weight polyethylene (UPE) or polyetheretherketone (PEEK). A plurality of the supports 11 are provided, and the thickness of the belt body 10 is increased. The pulley 3 is a portion 13 outside the belt main body 10 (the outer surface; the pulley 3 around which the belt main body 10 is wound, and the surface opposite to the surface on the side of 5). 5 in a direction away from 5 in the longitudinal direction of the belt main body 10 with an interval.

  Note that the upper end of each of the supports 11 exists on one horizontal plane in order to support the glass substrate W.

  When the pulleys 3 and 5 rotate, the belt body 10 and the supports 11 move, and the glass substrate W placed on the supports 11 moves in the horizontal direction indicated by the arrow AR1. It is designed to be transported.

  Further, the belt main body 10 is integrally formed by, for example, a toothed timing belt.

  That is, instead of adding another member to an annular member with a constant thickness by bonding or the like, thick portions and thin portions are formed alternately, but thick and thin portions are integrated. Is molded.

  When the pulleys 5 and 7 are wound around, the inner surface that contacts the outer periphery of the pulleys 5 and 7 is a surface on the side where the teeth of the toothed timing belt are not present, The surface on which the teeth exist is the outer surface, and the support 11 is provided at the tooth portion on the outer surface.

  In addition, as shown in FIG. 3 (the figure which shows the modification of a belt conveyor), you may use it with the tooth | gear part of a toothed timing belt inside. In this case, the support 11 is provided on a surface (outer surface) opposite to the surface on which the tooth portion of the toothed timing belt exists and corresponding to the surface on which the teeth are provided.

  Furthermore, as shown in FIG. 4 (a diagram showing a modified example of the belt conveyor), when a toothed pulley is used as each of the pulleys 3 and 5, the teeth are provided with teeth on both sides in the thickness direction. An attached timing belt may be used.

  As shown in FIG. 2, the support body 11 is formed in a columnar shape, the tip end portion is formed in a hemispherical shape, and the base end side is formed in a portion 13 where the belt main body portion 10 is thick. It is erected by being press-fitted into the provided cylindrical hole 17.

  As shown in FIG. 5 (a diagram showing a modification when the support body 11 is erected), the base end side of the support body 11 is provided in a thick portion 13 of the belt main body section 10. The support 11 may be erected by screwing into the formed hole.

  Further, the base of the support 11 does not protrude inside the belt main body 10. Further, the hole 17 provided in the belt main body 10 for installing the support 11 may be a blind hole that does not penetrate to the inside of the belt main body 10.

  According to the belt conveyor 1, since the support body 11 is erected on the portion 13 of the belt body portion 10 where the thickness is increased, the support body 11 can be easily installed on the belt body portion 10. Even if the belt main body portion 10 abuts against the pulley 3 or the pulley 5 and deforms in an arc shape during use, the belt main body portion 10 is not easily deformed at the thickened portion 13, and thus the support The portion where the body 11 is erected (the engagement portion between the belt main body portion 10 and the support body 11) is not easily deformed, and the support body 11 is less likely to be detached from the belt main body portion 10.

  Moreover, according to the belt conveyor 1, since the said belt main-body part 10 is shape | molded integrally, the belt main-body part 10 is formed firmly, and the said thick part in which the support body 11 is provided at the time of use Even if a moment is applied to the root of 13 (near the boundary between the thick portion 13 and the thin portion 15) over a long period of time, the possibility that the belt main body portion 10 is damaged can be avoided.

  In addition, since the belt main body 10 is integrally molded, the belt main body 10 can be easily manufactured.

  Furthermore, if a commercially available toothed timing belt is used as the belt main body part 10, it can be used as the belt main body part 10 simply by making a hole in the toothed timing belt. It becomes easy and the manufacturing cost can be reduced.

  Further, according to the belt conveyor 1, since the base end side is press-fitted into the hole 17 provided in the thick portion 13 of the belt main body 10, and the support 11 is erected, The configuration of the belt 7 is simplified, and the support 11 can be easily installed on the belt main body 10. Further, since the hole (hole into which the support 11 is press-fitted) 17 is provided in a portion 13 of the belt main body portion 10 where the thickness is increased, the belt main body portion 10 is connected to the pulley 3 during use. 5, the hole 17 is difficult to be deformed and hardly spread even when deformed into an arc shape, so that the support 11 is not easily detached from the belt main body 10.

  If the base 11 is screwed into a hole provided in the thickened portion 13 of the belt body 10 and the support 11 is erected, the support 11 can be installed more firmly. it can. Furthermore, by using an adhesive in combination with the above press-fitting and screwing, it can be made more difficult to slip.

  Further, since the heads of bolts and the like do not protrude inside the conveyor belt 7, it is not necessary to provide notches on the pulleys 3 and 5 around which the conveyor belt 7 is wound, and the configuration of the belt conveyor 1 is simplified. be able to.

  In addition, as shown in FIG. 6 (a diagram showing a modified example of the conveyance belt), even when a part of the belt main body in the width direction (for example, an intermediate portion such as a central portion) is thick, the thickness is large. It shall be included in the concept formed in the form which provided the site | part and the site | part with thin thickness alternately in the longitudinal direction. Thus, when the center part is thick, the said support body 11 is standingly arranged in this thick part.
