Description

  The present invention relates to a conveying device including a removing device that removes residues adhering to the conveying surface of a belt conveyor.

  As this kind of residue removing apparatus, the one described in Patent Document 1 below is known. In this removing device, the scraper is pressed against the belt surface to remove the residue. However, since the plate-shaped scraper is pressed against the belt surface, there is a problem that the belt surface is scraped by the scraper.

Therefore, when transporting food, the scraper material is changed or the pressing force is weakened to prevent scraping. However, when transporting highly viscous food such as chicken on a belt conveyor, the scraper If the pressing force of is not increased, there is a problem that the residue adhering to the belt surface cannot be completely removed.

In addition, when inspecting the bones remaining on the chicken with an X-ray inspection device, the residue must be completely removed from the surface of the belt on which the chicken is placed, so that the scraped belt scraped by the scraper is removed. The problem of sticking to chicken arises.

  An object of the present invention is to solve such a trade-off problem, and it is an object of the present invention to provide a conveying device that can reliably remove the residue on the surface of the belt without causing scraping of the belt.

FIG. 1 is an explanatory diagram for explaining the solution principle of the present invention. In this figure, the first device is a transport device A that feeds an object to be transported M from a first belt conveyor 1 on the upstream side to a second belt conveyor 2 on the downstream side. The upstream side conveyance surface 20 is positioned below the downstream side conveyance surface 10 of the first belt conveyor 1, the upstream side conveyance surface 10 and the downstream side conveyance surface 20 are brought close to just before contacting each other, and the first The conveying surface 10 of the belt conveyor 1 has a shape or material in which the frictional force exerted on the conveyed object M is smaller than the frictional force exerted on the conveyed object M by the conveying surface 20 of the second belt conveyor 2. .

Specifically, flat belts used for the belt conveyors 1 and 2 are mainly made of polyurethane on the transport surface and polyester on the back surface. However, the transport surface of the second belt conveyor can be replaced with soft polyurethane. The friction coefficient of the second belt conveyor can be made larger than the friction coefficient of the first belt conveyor. Further, if the transport surface of the first belt conveyor 1 is finished smoothly and the transport surface of the second belt conveyor 2 is used for inclined transport or grip transport, the friction coefficient of the second belt conveyor 2 can be increased. it can.

In addition, the second device is a transfer device A configured to send an object to be transferred M from the first belt conveyor 1 on the upstream side to the second belt conveyor 2 on the downstream side, and the upstream side of the second belt conveyor 2. The transport surface 20 is positioned below the downstream transport surface 10 of the first belt conveyor 1, the upstream transport surface 10 and the downstream transport surface 20 are brought close to contact with each other, and the second belt conveyor 2 The hook is formed on the transport surface so that the transport object M is more hooked than the first belt conveyor 1.

For example, if a flat belt having an embossed surface or fine protrusions is used as the second belt conveyor, the catch on the object to be conveyed M can be increased.

With such a configuration, when the object to be conveyed M is sent from the upper first belt conveyor 1 to the lower second belt conveyor 2, the object M adhered to the conveying surface 10 of the first belt conveyor 1 becomes lower. Since the conveying surface 20 of the two-belt conveyor 2 is touched and scooped up from the bottom, the object to be conveyed M adhering to the conveying surface 10 is forcibly peeled off by the second belt conveyor 2. Therefore, the second belt conveyor 2 can forcibly remove the residue on the first belt conveyor 1 without providing a scraper separately.

In FIG. 1, the upstream first belt conveyor 1 is provided at a high position and the downstream second belt conveyor 2 is provided at a low position. However, the present invention is not limited to this. For example, the first belt conveyor 1 If the upstream end portion of the second belt conveyor 2 is set lower than the downstream end portion, the arrangement configuration shown in FIGS. 2 to 5 may be employed.

The third device is an X-ray inspection apparatus using the transfer device according to the first and second devices, and is a conveyor arranged in the X-ray inspection device to convey an object to be inspected. Is a first belt conveyor, and the second belt conveyor is a belt conveyor of a sorting apparatus disposed at a subsequent stage of the X-ray inspection apparatus.

As a result, the residue adhering to the first belt conveyor can be removed from the downstream end of the inspection line provided with the upstream X-ray inspection apparatus and the downstream sorting apparatus only by incorporating the conveying apparatus according to the present invention. Since it can be removed at the portion, misjudgment of the inspection result due to the residue can be avoided.

  According to the present invention, since the residue adhered to the belt conveyor can be effectively removed without removing the shavings from the belt, any food can be directly placed on the belt conveyor and conveyed. Therefore, it is possible to carry out conveyance without causing misjudgment as a conveyance device of an X-ray inspection apparatus that inspects foreign substances in food.
