Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an article redirection device for redirecting an article having a rectangular cross section.

``Prior Art'' Conventionally, as a device for changing the direction of articles, two transport conveyors are arranged side by side or intersected, and the downstream transport conveyor is operated at high speed.
When an article is transferred from an upstream conveyor to a downstream conveyor, the article is transferred while rotating by taking advantage of the speed difference between the two, or there is a case where one side of the article is transferred along the conveyor. It is known that a stopper is disposed in contact with the stopper, one side of the article being conveyed is brought into contact with the stopper, and the article is rotated around the contact portion with the stopper.

Other devices with various configurations are known, such as those in which the article is held by a holding head and the article is rotated by rotating the holding head.

``Problem that the invention seeks to solve'' However, in general, conventional direction changing devices, such as the former two devices, which are simple in construction and inexpensive, are unable to reliably rotate the article by a predetermined amount. On the other hand, the latter device, which can reliably rotate an article by a predetermined amount, has the disadvantage of being complex and expensive.

"Means for Solving the Problems" In view of such circumstances, the present invention includes a supply conveyor for conveying articles having a rectangular cross section, and a supply conveyor provided on both sides of the supply conveyor.
a guide member that guides both sides of the article so that the article does not rotate; a screw that is rotatably supported so as to intersect the conveyance direction of the article by the supply conveyor; a spiral groove for receiving an article fed obliquely to the axis of the screw and supporting mutually adjacent side surfaces of the article; and a spiral groove disposed parallel to the screw and engaged with the spiral groove. a guide member that guides the oblique article from the side opposite to the screw so that the article does not separate from the spiral groove and rotate; A carry-out conveyor receives the article with both sides guided by guide members facing forward and backward in the conveyance direction, and a carry-out conveyor provided on both sides of the carry-out conveyor to prevent the articles conveyed by the carry-out conveyor from rotating. and a guide member that guides both sides different from the both sides guided by the guide member of the supply conveyor.

"Operation" According to such a configuration, the article can be reliably rotated simply by passing the article between the conveyor and the screw, and the article direction changing device is composed of the conveyor, the screw, and the guide member. Therefore, it can be manufactured at low cost.

"Example" The present invention will be explained below with reference to the illustrated example.
In the figure, a screw 2 having a spiral groove 1 formed on its outer periphery is horizontally supported above a mounting plate 4 on which an article 3 is placed and slid, and is driven by a drive motor (not shown) as shown in the arrow. It is designed to be rotated in the direction.

The cross-sectional shape of the valley of the spiral groove 1 formed in the screw 2 is approximately rectangular in the cross-sectional shape of the article 3.
The body of the article 3 is held between the spiral groove 1 and a guide member 5 arranged parallel to the screw 2 and fixed to a machine frame (not shown). The rotation of the article 3 is restrained while allowing it to be conveyed to the left.

At both sides of the screw 2, there are supply conveyors 6 for supplying articles 3 to the screw 2;
A carry-out conveyor 7 is provided to carry out the articles 3 from the screw 2. In this embodiment, the longitudinal direction of both conveyors 6 and 7, that is, the article conveyance direction, is set relative to the axis of the screw 2, that is, the article conveyance direction.
The conveyors 6 and 7 are set to form an angle of 45°, so that both conveyors 6 and 7 intersect at an angle of 90°.

Each of the conveyors 6 and 7 is disposed so that the article placement surface thereof is on the same plane as the placement plate 4, and articles 3 and 3 are placed on both sides of each conveyor 6 and 7.
Each pair of guide members 8 is attached to prevent the articles 3 from falling off and to prevent the articles 3 from rotating during transportation. One guide member of each pair of guide members 8 of both conveyors 6 and 7 is integrally continuous with the guide member 5 disposed facing the screw 2.

In the above configuration, the article 3 on the supply conveyor 6 is conveyed and rotated while facing forward in the conveyance direction, with rotation of the side surface of the body being restrained by the pair of guide members 8. Screwyu 2
is passed into the spiral groove 1 of the At this time, as mentioned above, the article conveyance direction of the supply conveyor 6 and the article conveyance direction of the screw 2 intersect at an angle of 45 degrees, so the article 3 is tilted at 45 degrees with respect to the article conveyance direction of the screw 2. Supplied in condition.

The article 3 delivered from the supply conveyor 6 into the spiral groove 1 of the screw 2 at an angle of 45° is
Due to the cross-sectional shape of the spiral groove 1 and the guide member 5, rotation is restrained in a 45° tilted state, and the screw 2 is transported on the mounting plate 4 in this state as it rotates. .

The article 3 conveyed by the screw 2 is then transferred from the screw 2 to the carry-out conveyor 7, and is conveyed by the carry-out conveyor 7 in a state in which rotation is also restrained. During the delivery, the article conveyance direction of the screw 2 and the article conveyance direction of the take-out conveyor 7 intersect at an angle of 45 degrees, so the article 3 from the screw 2 is tilted 45 degrees to the take-out conveyor 7. As a result, the articles that have been conveyed facing forward on the supply conveyor 6 are turned 90° and conveyed on the discharge conveyor 7.

In the above embodiment, the supply conveyor 6 and the discharge conveyor 7 are arranged to intersect with the axis of the screw 2, but both conveyors are
The guide members 8 may be arranged parallel to the axis of the guide member 8, and the pair of guide members 8 may be arranged at an angle so as to intersect the axis.

"Effects of the Invention" As described above, according to the present invention, it is possible to reliably change the direction of an article with a simple and inexpensive configuration.
