[Industrial applications]

 The present invention relates to a support guide for a conveyor belt.

[0002]

[Prior Art]

 A supporting guide described in Japanese Utility Model Publication No. 2-40010 is known as a support guide for supporting a conveyor section of a conveyor belt from below and enabling smooth traveling of the conveyor belt. This support guide 1 (see FIG. 2) is formed by adhering a thin plate-like liner 3 made of ultra high molecular weight polyethylene to the upper surface of a rubber bar 2 having a rectangular cross section, and a plurality of them are attached to a conveyor belt C. A rail 4 with a longitudinal groove which is arranged on the lower side in parallel with the conveyor belt C in a trough shape and is fixed to the center of the lower surface of the rubber bar 2 or an ant formed in the center of the lower surface of the rubber bar 2. The groove is fixed to the lower frame F with bolts 5 and nuts 6.

[0003]

[Problems to be solved by the device]

 However, since the above-mentioned support guide 1 has a plate-like liner 3 made of ultra-high molecular weight polyethylene integrated with the upper surface of the rubber bar 2 by adhesion, when the plate-like liner 3 on the surface is worn, it is supported. Since the entire guide 1 needs to be replaced, the rubber bar 2 is wasted, and the support guide 1 is detached from the frame F and lifted up during the replacement, so that the conveyor belt C is lifted and supported. It was necessary to form a space above the guide 1, the replacement work was troublesome, and the work required a long time. Also, when it is desired to replace the plate-shaped liner 3 with another synthetic resin (for example, nylon) depending on the installation location of the support guide 1 or the like, it is impossible to replace it. It had to be pre-bonded to the rubber bar. Further, since the rubber bar 2 and the plate-like liner 3 were adhered to each other by overlapping them before vulcanization and vulcanizing at a temperature of 150 to 165 ° C., the support guide 1 was cooled by cooling after vulcanization. There was a problem that the warp occurred.

This invention makes it possible to replace only the plate-like liner by detachably connecting the plate-like liner and the rubber bar, and to eliminate the need to adhere the plate-like liner by vulcanizing the rubber bar. The support guide is prevented from warping.

[0005]

[Means for Solving the Problems]

 A conveyor belt support guide according to the present invention is provided with a ridge having the above-mentioned rubber bar and plate-like liner projecting on the lower surface of the plate-like liner in parallel with the lengthwise direction, and a ridge on the rubber-bar. It is detachably connected by fitting with a longitudinal groove formed at a corresponding position, and a locking means is provided to prevent sliding of the plate liner in at least one direction. Is characterized by. Depending on the purpose, the plate-like liner may be ultra-high molecular weight polyethylene, monomer cast nylon, polyacetal, polycarbonate, polypropylene, polyamide, polyphenylene oxide, polyethylene terephthalate, polybutylene terephthalate, polyacrylate, polysulfone, polyethersulfone. It can be made of any synthetic resin such as polyimide, polyphenylene sulfide, or the like.

[0006]

[Action]

 By aligning the end of the groove on the rubber bar with the end of the ridge on the plate liner and sliding the plate liner in the length direction, the above ridge is extended into the groove. Fitting over, the plate liner is joined to the rubber bar, and the plate liner is removed from the rubber bar by sliding the plate liner in the opposite direction. Then, when the one-way sliding of the plate-shaped liner is stopped by the locking means, when fixing the support guide, the direction is regulated according to the traveling direction of the conveyor belt, so that the friction with the conveyor belt is prevented. It is possible to prevent the plate-shaped liner from coming off. In addition, when the two-way sliding is stopped by the locking means, the plate-shaped liner does not slip out even if the support guide is fixed in any direction with respect to the traveling direction of the conveyor belt.

[0007]

【Example】

 A support guide 10 of Example 1 shown in FIG. 1 includes a rubber bar 11 having a rubber hardness (JIS-A rubber hardness) of 40 to 60 degrees, and a plate-like liner 12 made of ultra-high molecular weight polyethylene having a molecular weight of 1,000,000 or more. The plate-shaped liner 12 is provided with protruding L-shaped projections 12a on both left and right edges over the entire remaining length except one end 11b in the longitudinal direction. A recessed groove 11a that can be fitted with the protrusion 12a of the plate-like liner 12 is provided over the entire length except the one end in the longitudinal direction, and one end upper portion of the rubber bar 11 (a portion where the above-mentioned recessed groove 11a is not formed) ) 11b forms a stopper (locking means) for preventing the plate-shaped liner 12 from sliding in one direction. The grooved rail 13 is fixed to the lower surface of the rubber bar 11 as in the conventional case. Alternatively, the fixing of the grooved rail 13 may be omitted, and the dovetail groove formed on the lower surface of the rubber bar 11 may be directly fixed to the frame F by the bolt 5 (see FIG. 2).

In the support guide 10 described above, by sliding the plate-like liner 12 along the upper surface of the rubber bar 11 in the direction of arrow A from the upper right of the rubber bar 11, the groove 11 a of the rubber bar 11 is formed. When the ridge 12a of the plate-shaped liner 12a is fitted to the stopper and the end (left end) of the ridge 12a contacts the stopper 11b of the rubber bar 11, the movement of the plate-shaped liner 12 is stopped and the rubber bar 11 and the plate-like liner 12 are joined. Then, the heads of the bolts 5 of FIG. 2 are fitted to the grooved rails 13 on the lower surface of the rubber bar 11 and attached to the frame F as in the conventional case. However, the stopper 11b is oriented in the direction in which the conveyor belt C advances.

In Example 1, the upper surface portion of the rubber bar 11, that is, the portion in contact with the lower surface of the plate-like liner 12 is replaced with rubber having a high hardness, and it can be used under particularly severe operating conditions. In Example 2 of FIG. 3, the upper surface portion 14a of the rubber bar 14 is formed of hard rubber having a rubber hardness of 70 to 85 degrees, and the body portion 14b thereunder is formed of the same rubber as that of the embodiment of FIG. The upper surface portion 14a and the main body portion 14b are integrated by vulcanization adhesion. The recessed grooves 14c that fit with the protrusions 12a of the plate-like liner 12 are formed on the left and right edges of the upper surface of the main body portion 14b.

In Example 3 of FIG. 4, the sliding of the plate-like liner 12 is restrained in two directions, one end side and the other end side, along the length direction of the upper portion of the support guide 10. A lateral hole is preliminarily formed at a plurality of positions so as to pass through the right and left ridges 12a, 12a of the plate-like liner 12, and a synthetic resin head pin (locking means) 15 is inserted into the lateral hole. A split pin 16 is inserted into the tip hole of the pin 15 to prevent the pin 15 from slipping out. In this case, the concave groove 11a of the rubber bar 11 and the protrusion 12a of the plate liner 12 are provided over the entire length of the rubber bar 11 and the plate liner 12, respectively, and the stopper 11b of FIG. 1 is not formed.

The ridges on the lower surface of the plate-like liner 12 may be provided in various shapes other than the above, and the concave groove of the rubber bar 11 may be provided in various shapes depending on the shape. In Example 4 of FIG. 5, one strip-shaped trapezoidal protrusion (ant) 12b is provided at the center of the lower surface of the plate-like liner 12, and a trapezoidal recessed groove (ditch) is formed in the rubber bar 11. It was done. Further, in Example 5 of FIG. 6, two right and left bead-shaped protrusions 12c are provided on the lower surface of the plate-like liner 12, and the rubber bar 11 corresponds to the bead-shaped protrusions 12c described above. It is a groove in a book.

[0012]

[Effect of the device]

 As described above, the present invention provides a rubber bar having a rectangular cross section and a plate-like liner on the upper surface thereof by fitting the ridges provided on the plate-like liner with the concave grooves provided on the rubber bar. Since it is detachably coupled, the plate liner can be easily attached and detached by sliding the plate liner along the upper surface of the rubber bar in the length direction. Therefore, if the plate liner becomes worn, you can replace only the plate liner by sliding the plate liner lengthwise while keeping the rubber bar secured to the frame under the conveyor belt. Therefore, the replacement work is facilitated, the working time is shortened, and the waste of the rubber bar can be eliminated.

Further, by preparing various types of plate-shaped liners such as ultra-high molecular weight polyethylene and nylon, any plate-shaped liner can be attached to an existing rubber bar for use depending on the purpose. It is possible to reduce the inventory quantity of the rubber bar as compared with the case where the rubber bar and the plate-like liner are bonded. In addition, since only the rubber bar needs to be vulcanized during manufacturing, the product support guide is not warped as in the conventional case. Further, since the locking means is provided to prevent the plate liner from sliding in at least one direction, the plate liner is displaced in the traveling direction of the conveyor belt due to friction with the conveyor belt. There is also no risk that the plate-shaped liner will fall out during use.
