  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a log transport device according to an embodiment of the present invention, FIG. 2 is a side view thereof, FIG. 3 is an enlarged schematic view of a foreign matter removing and collecting means, and FIG.

  The log transport device A according to the present embodiment has two pairs of endless drive chains 10 and 10 arranged in parallel at intervals, and each of the drive chains 10 and 10 has a substantially vertically long elliptical shape having the same shape. It is comprised so that it may circulate through a circulation path.

  .. Are attached to the drive chain 10, and the log R is substantially supported by the support 11. The support 11 is a metal member having a substantially V-shaped portion 11v or a curved arc-shaped portion that receives the end of the log R. It is attached so that it can be tilted to a predetermined angle of approximately 120 degrees by an external force.

  Each end of the log R is placed on each support tool of both drive chains when the support tool 11 is in a normal state, and is substantially parallel to the floor surface between the support tools of both drive chains 10 and 10. Is stored and stored.

  The two drive chains 10 and 10 are circulated and moved at a constant speed by a drive source (not shown), so that a large number of logs R are stretched between the support members in parallel with the floor surface and discharged while being stored. Transport to position.

  At the log discharge position Ax, a cam 12 forcibly tilting the support tools 11 and 11 and a chute 13 for receiving the discharged log R are attached, and the support tools 11 and 11 move to this discharge position. When it comes, the support tools 11 and 11 come into contact with the cam and are inclined, and the log R on the support tool rolls onto the chute 13.

  In the log transport device A of the present embodiment, there is provided a foreign matter removing and collecting means for collecting the foreign matter S adhering to the drive chain 10 characteristically.

  The foreign matter removing and collecting means includes a suction and collecting means 21 for sucking and collecting foreign matters and a brush means 20 disposed so as to come into contact with the drive chain 10, and the foreign matter scraped by the brush means 20 is sucked and collected. It is configured to be sucked and collected by means.

  The brush means 20 is positioned so as to be in contact with the drive chain 10 and is fixed to, for example, a frame body (not shown). As the drive chain 10 moves, the bristles of the brush means 20 touch the surface of the drive chain. It is configured to scrape off the foreign matter S adhering to the surface. The brush means 20 may be slid on the surface of the drive chain 10 by reciprocating within a predetermined range using the drive means without being fixed.

  The brush means 20 can be a general brush in which a large number of natural or synthetic hairs and elongated sponges are gathered. The material of the hairs, the length of the bristle feet, the hardness, etc. It is determined appropriately in consideration of the wiping condition of necessary oils and fats and the scraping condition of foreign matters. When the lubricating oil or the like of the drive chain 10 is scraped off by the brush means 20, the drive chain may be lubricated at an appropriate location.

  On the other hand, the suction and recovery means 21 installed in the vicinity of the brush means 20 is a device that mainly sucks and removes and collects foreign matters scraped by the brush means 20. Of course, not only the foreign matter S scraped off by the brush means 20, but also the foreign matter adhering to the drive chain 10 may be directly sucked. The suction collecting means 21 is not particularly limited as long as it has a function of sucking and collecting foreign matter, but in the log transport device of this embodiment, it is in the vicinity of the brush means and in the vicinity of the drive chain 10. A suction head 21H having a suction port 21a that is open to the suction head, a suction conduit 21L extending from the suction head 21H, a foreign matter recovery tank 21T for collecting foreign matter conveyed through the suction conduit 21L, and substantially Are combined with a suction pump 21P for providing a suction function. The suction head, the suction conduit, and the recovery tank can be made of a material such as metal or plastic material.

  The suction port 21a of the suction recovery means 21 is desirably arranged so as to surround the drive chain 10. For example, as shown in FIG. 4, as a substantially U-shaped suction head, if a slit-shaped suction port is provided at a position facing the drive chain of the suction head, the drive chain is surrounded while avoiding the support. A suction port can be arranged. It is further preferable that the brush means is also substantially U-shaped.

  A suction operation can be performed continuously or at an appropriate interval from the suction port 21a of the suction recovery means 21. The suction operation can be performed by turning on and off the suction pump 21P. If the suction operation is always performed continuously, the paper dust to be attached to the drive chain 10 is sucked, so that the scattered paper powder adheres to and mixes with the lubricating oil of the drive chain 10 to generate foreign matter itself. The effect which prevents is also acquired.

  Here, the distance between the suction port 20a of the suction recovery means 21 and the brush means 20 can be appropriately set according to the range of the suction force of the recovery means. The suction force is determined depending on how much foreign matter is to be sucked, and the foreign matter attached to the brush 20 can be sucked by the suction force so as to be separated from the brush means 20.

  The arrangement relationship between the brush means 20 and the suction port 21a is that if the brush means 20 is fixed to the frame and the drive chain 10 is moved in a state where the brush means 20 is in contact with the drive chain 10, the foreign matter is scraped off. Since the scraped foreign matter accumulates on the rear side surface of the brush 20, particularly in this case, as shown in FIG. (Direction) It is desirable to be positioned on the rear side.

  Here, the position where the brush means 20 and the suction head 21H (suction port 21a) are provided can be an appropriate position in the middle of the circulation path of the drive chain 10, but preferably on the support 11. The log R does not exist and is in the middle from the log discharge position Ax to the log receiving position, and among them, the lowermost part of the longitudinal circulation circuit of the drive chains 10 and 10 is particularly preferable.

  In addition, although the said form is a form provided with both a brush means and a suction collection means, this invention is not necessarily limited to this form. For example, it may be possible to provide only the suction recovery means without providing the brush means. The specific shape and installation mode of the suction means in this case can be the same as the suction recovery means in the form including the brush means. However, the suction force is preferably set higher because the brush means does not assist the separation of foreign matter from the chain.

  The present invention is not limited to a log transport device in which a toilet paper roll or kitchen paper roll is wound from a roll so as to have a product diameter, such as cloth, non-woven fabric, and PP sheet. It can be made into the conveying apparatus made into what rolled up various sheets and made it roll shape.

It is a front view of the log conveyance device concerning this embodiment. It is the side view. It is the schematic of a brush means and a suction collection means. It is a perspective view which shows an example of a suction head.
