Abstract

PURPOSE:To eliminate any slip on a conveyor belt together with elimination of gaps and concaves possibly generated between the belt conveyors arranged in parallel with each other, by providing notches on the edges of end plate S inside the terminals of a conveyor belt and bringing rollers with small diameters arranged in said notches in contact with the inner face of the conveyor belt. CONSTITUTION:End plates 2 are installed inside the terminals of an endless conveyor belt 1, and notches 6 are formed on the edges of end plates 2. Roller 3 with small diameters are disposed inside the notches 6 with a penetrating shaft 7. The conveyor belt 1 is moved while its inner face is in contact with the rollers 3 and the radius of curvature being considerably large at the terminal area. Further, if the rollers 3 are supported by the end plates 2, bent conveyors can be arranged in series very closely to each other, thus eliminating generation of an y large gap or concave between them.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a belt conveyor used for conveying workpieces in an equipment assembly process.

[Background Art] As shown in FIG. 2, a commonly used belt conveyor is a belt conveyor installed between a pair of tension rollers 16 on the outer periphery of a roller 11 supported by a bearing 10 attached to a shaft 13. An endless conveyor belt 12 driven by a drive roller 17 is brought into contact with the belt. in this case,
When two belt conveyors are arranged in series and a workpiece is transferred from one belt conveyor to a belt conveyor (tH), a recess 14 is created between both belt conveyors due to the outside diameter of the roller 11 being deviated from the sky. The workpiece falls into these four parts 14 or moves up and down, which limits the workpieces that can be transported.In order to reduce the outer diameter of the roller 11, as shown in FIG. It is conceivable to provide a bearing 10 and use this bearing 10 to rotatably support the shaft portions at both ends of the roller 11, but even if the diameter of the roller 11 is made smaller, it is possible to The bearings 10 of the belt conveyors collide with each other, creating a gap between both belt conveyors.

For this purpose, instead of being supported by rollers 11 as shown in FIG. 4, an end plate 20 with a tapered end is provided so that the conveyor belt 12 slides on the surface of this end plate 20. There is something. In this example, the recesses that occur between the belt conveyors arranged in series are reduced, and although favorable results are obtained in terms of dropping the workpiece and vertical movement, the open surface friction between the end plate 2o and the conveyor belt 12 The resistance may cause the conveyor belt 12 to slip and not be continuously fed at a constant speed.

[Objective of the Invention 1 The present invention has been made in view of the above points, and its purpose is not only to prevent the conveyor belt from slipping, but also to prevent gaps and large The goal is to provide a belt carrier that does not have four parts.

[Disclosure of the Invention] Accordingly, the present invention provides an end plate installed in the end of an endless conveyor belt, a notch provided at the end of the end plate, and a small-diameter roller placed through the shaft in the notch. It is characterized by the fact that the rollers are brought into contact with the inner surface of the conveyor belt, and instead of supporting the rollers with side frames, the rollers are rolled using end plates installed inside the conveyor belt. . It is preferable to use a radial bearing itself as the roller in this one position.

The present invention will be described in detail below based on the disclosed embodiments.
As shown in the figure, at the end of the endless conveyor belt 1 which is in contact with a drive roller 5 between tension rollers 4 and 4 and is driven by this drive roller 5, there is an end plate supported by a separate member. 2 is installed. The end of the end plate 2 is shaped like a knife with a thin thickness, and is provided with a plurality of notches 6, 6. In each of these notches 6, several rollers 3 made of radial bearings having a small diameter and a short length in the axial direction are installed by passing a shaft 7 through them.

The conveyor belt 1 moves while its inner surface is in contact with these rollers 3, and the curvature at the end portions is quite large. Furthermore, since the rollers 3 are supported not by the side frames but by the end plates 2 installed inside the conveyor belt 1, even when belt conveyors are lined up in series, they can be installed close to each other. At the same time, the four parts formed between the two are small, and the only workpieces that fall or move up and down are very small ones, which reduces the restrictions on the workpieces that can be transported.

[Effects of the Invention] As described above, in the present invention, an end plate is installed within the end of an endless conveyor belt, a notch is provided at the end of the end plate, and a small diameter roller is placed through the shaft in the notch. Since this roller is brought into contact with the inner surface of the conveyor belt, when the belt conveyors are arranged side by side, the supporting members of the rollers do not impose restrictions on arranging both belt conveyors close to each other. There are no large recesses between belt conveyors, and workpieces can be transported with less depression or vertical movement, and there are fewer restrictions on the workpieces that can be transported.
