  The cleaning devices described in Patent Documents 1 and 2 have a structure in which only one side of a conveyor chain is cleaned with a brush, and there is a problem that it is difficult to remove dust attached to the other side. This problem can be easily solved by arranging brushes on both sides of the conveyor chain. However, in that case, it is uneconomical to provide a rotation drive source for each brush, so both rotations can be achieved with one rotation drive source. It is desirable to have a structure that synchronously rotates the brush.

The present invention relates to a conveyor chain configured such that a pair of left and right guide rollers pivotally supported on an attachment travel on the respective conveyor rails, and only one rotational drive source is required for cleaning both sides of the conveyor chain with a pair of rotating brushes. Furthermore, it is an object of the present invention to provide a conveyor chain cleaning device and a method for attaching the same , which can easily cope with a change in specifications of the distance between the conveyor rails and the width of the conveyor chain itself.

The cleaning device of the present invention has a structure in which a support bracket is detachably attached to each conveyor rail with bolts when cleaning the conveyor chain from both sides with a pair of rotating brushes. A cleaning device can be easily mounted, and the conveyor chain can be cleaned at a desired location.
Also, by interposing a spacer between the conveyor rail and the support bracket, the distance between the support brackets, that is, the distance between the rotating brushes can be easily adjusted. The cleaning device can be installed regardless of the difference in the width dimensions.
Furthermore, the cleaning device of the present invention is capable of synchronously rotating two rotary brushes with a single drive source, and has a configuration in which a drive transmission chain is wound between the sprockets of each support bracket as a drive mechanism for synchronous rotation. When the distance between the support brackets is changed, it is only necessary to change the length of the drive transmission chain, and precise adjustment of the drive mechanism is not required.

Further, in the cleaning using the cleaning device according to the present invention , a spacer is interposed between the conveyor rail and the support bracket according to a difference in distance between the conveyor rails or a width of the conveyor chain itself. Thus, the distance between the rotating brushes is adjusted .

  According to the present invention, when the conveyor chain is cleaned from both sides with a pair of rotating brushes, the support brackets are detachably attached to the respective conveyor rails with bolts, so that any extension portion of the conveyor rail can be quickly and easily installed.

A pair of support brackets 10A and 10B that pivotally support the rotary brushes 8A and 8B and are detachably attached to the conveyor rails 4A and 4B by bolts 9, a drive source 11 of the rotary brushes 8A and 8B, and support brackets. A drive mechanism 14 is provided which has a structure in which a drive transmission chain 13 is wound between sprockets 12A and 12B attached to 10A and 10B. The drive mechanism 14 rotates both rotary brushes 8A and 8B synchronously.

  One support bracket 10 </ b> A has a U-shaped cross section and is positioned so that its opening faces the conveyor chain 1. One surface (horizontal plane) of the connection bracket 15 having an L-shaped cross section is fastened and fixed to the upper surface of the support bracket 10 </ b> A by a plurality of fixing bolts 16. The other surface (vertical surface) of the connecting bracket 15 is detachably attached to a flat plate mounting seat 17 fixed to the outer surface of the web 4Aa of the conveyor rail 4A by a plurality of bolts 9 with hexagonal holes.

  In the internal space of the U-shaped portion of the support bracket 10A, a rotating brush 8A is accommodated so as to be rotatable around the vertical axis. The rotating brush 8A has a structure in which filaments made of synthetic fibers or the like are radially planted on the outer periphery of the rotating shaft 18, and has a substantially cylindrical shape. The rotary shaft 18 is supported on the support bracket 10A via a bearing. The lower end of the rotating shaft 18 extends further downward from the lower surface of the support bracket 10A. The extending portion is attached to the output shaft of the driving source 11 via the joint 19 after the driving sprocket 12A is attached to the shaft. It is linked to.

  In the present embodiment, the drive source 11 is composed of an air motor 6 that receives supply of compressed air and rotates its output shaft. A drive source support bracket 20 is fixed to the lower surface of the support bracket 10 </ b> A, and the air motor 6 is attached to the drive source support bracket 20.

In the internal space of the U-shaped portion located at, a rotating brush 8B is accommodated so as to be rotatable around the vertical axis. Then, one surface (horizontal plane) of the connection bracket 15 having an L-shaped cross section is fastened and fixed to the upper surface of the support bracket 10 </ b> B by a fixing bolt 16. The other surface (vertical surface) of the connecting bracket 15 is detachably attached to the mounting seat 17 fixed to the outer surface of the web 4Ba of the conveyor rail 4B by means of bolts 9.

  In the support bracket 10B, a separate U-shaped portion is formed below the U-shaped portion that houses the rotating brush 8B, and a vertical driven shaft 21 is provided in the internal space of the lower U-shaped portion. Is housed rotatably. A driven sprocket 12B is attached to the driven shaft 21, and a drive transmission chain 13 is wound around the sprocket 12B and the sprocket 12A. The sprockets 12A and 12B and the drive transmission chain 13 constitute a drive mechanism 14 that rotates the rotating brushes 8A and 8B synchronously. As a conversion mechanism for the rotation direction of the rotating brush 8B, a first gear 22 is axially attached to the driven shaft 21, and the first gear 22 is attached to the lower end of the rotating shaft 18 of the rotating brush 8B. It meshes with the gear 23.

  The cleaning device 7 according to the present invention has the above-described configuration. When the conveyor chain 1 travels and moves, when the compressed air is supplied to the air motor 6 and rotated, for example, as shown in FIG.

Therefore, for example, even when the cleaning device 7 is mounted on the conveyor rails 4A and 4B only when periodic cleaning is performed, and the other parts are removed from the conveyor rails 4A and 4B, it does not require much labor as an attaching / detaching operation.

  Further, by interposing a spacer or the like between the conveyor rails 4A and 4B and the support brackets 10A and 10B, for example, by interposing a spacer having an appropriate thickness between the mounting seat 17 and the connection bracket 15, the support bracket The distance between 10A and 10B, that is, the distance between the rotating brushes 8A and 8B can be easily adjusted. Therefore, the cleaning device 7 of the present invention can easily cope with the difference in specifications of the distance dimension between the conveyor rails 4A and 4B and the width dimension of the conveyor chain 1 itself. In addition to the structure in which the spacer is interposed, for example, the support brackets 10A and 10B and the connection brackets 15 are fastened and fixed by the fixing bolts 16 through the long holes, and the positions of the fixing bolts 16 with respect to the long holes are changed. You may make it adjust the distance between bracket 10A, 10B.

  Furthermore, since the cleaning device 7 of the present invention has a structure in which the two rotary brushes 8A and 8B are synchronously rotated by the single drive source 11, the manufacturing cost can be reduced. As the drive mechanism 14 for synchronously rotating the rotating brushes 8A and 8B, the drive transmission chain 13 is hung around the sprocket 12A on the support bracket 10A side and the sprocket 12B on the support bracket 10B side. When the distance between them is changed, it is only necessary to change the length of the drive transmission chain 13, and a precise adjustment operation of the drive mechanism 14 is not required.
