Description

[Detailed Description of the Invention] This invention relates to an endless round belt conveyor used, for example, in the glazing process of tiles or in conveying tiles from one process to the next in the production of tiles.

Generally, exterior tiles have several grooves on the back side of the tile to improve adhesion when attached to a wall, but recently the grooves have become deeper, with 2mm grooves now appearing.

In conventional endless round belt conveyors, the round belts are stretched one by one at a distance, so if tiles with deep grooves on the back like the one shown above are placed on this conveyor and transported, the round belt will be It easily fits into this groove, and its position is regulated by a groove on the back of the tile at a pitch different from the groove pitch provided on the roller. Therefore, when the round belt carrying the tiles moved forward, the 7th
As shown in the figure, the round belt 4f at the roller 1f part is subjected to lateral force by the groove on the back side of the tile 5f, causing it to protrude from the belt groove 2f of the roller and become misaligned, or become entangled with other round belts. There was a problem that came up.

Therefore, the present invention is designed to eliminate the above problem. Even if the round belt gets stuck in the groove when transporting grooved tiles, the round belt will come off the belt groove of the roller and the other round belts will be moved. It is an object of the present invention to provide an endless round belt conveyor that can prevent entanglement.

The drawings showing the embodiments of the present application will be described below. In FIGS. 1 to 6, reference numerals 1 and 1 denote rollers that are driven by a known drive mechanism (not shown) to rotate in the direction of the arrow. 2, 2 are belt grooves, and a plurality of belt grooves are formed corresponding to each roller 1. The distance between the belt grooves 2, 2 is as shown in FIG.
When the round belt 4a hung on the belt groove 2a is about to be pushed out of the belt groove 2a due to the lateral force shown by the arrow A, the round belt 4a hung on the adjacent belt groove 2b The gap is such that it can come into contact with the belt 4b and be prevented from coming off the belt groove 2a. 3 is an intermediate support roller, which is rotatably supported as is well known. As is well known, the round belt 4 has a circular cross section. Its diameter is 3 mmφ to 5 mmφ. It is also formed using polyurethane, for example. This belt is stretched in the corresponding belt grooves 2 of both rollers 1 with an elongation of about 5 to 10%. Reference numeral 5 denotes a tile exemplified as an object to be transported, and a plurality of grooves 6 are formed on the back surface of the tile.

In the structure described above, as shown in FIGS. 1 and 2, tiles 5 placed on a plurality of round belts 4, 4, .

In this case, since a plurality of groups of round belts 4 are arranged, each group having two adjacent round belts, at least one round belt 4 in each group can come into contact with the bottom surface 5a of the tile 5, as shown in FIG. Highly sexual. Therefore, the number of round belts that get stuck in the grooves 6 is reduced, so that the tiles 5 are conveyed smoothly. In this case, as shown in FIG. 3, two groups separated from each other have one round belt 4c, 4
If d contacts the bottom surface 5a, no round belt 4 will fit into the groove 6.

Further, in the above case, the two round belts 4, 4 get stuck in the groove 6 at the same time as shown in FIG. As it approaches, the round belt 4a fitted into the groove 6 is moved by the side wall 6a of the groove 6 in a lateral direction as indicated by arrow B in FIG. 5 (as indicated by A in FIG. 6). receive the power of However, since the distance between the belt grooves 2 and 2 in the roller 1 is set as described above, even if the round belt 4a is about to come off the belt groove 2a, the belt 4a will come into contact with the adjacent belt 4b, and the two belts will be separated. In order to respond to the above force by the belts 4a and 4b,
The belt 4a is prevented from coming off the belt groove 2a. Although this embodiment shows a case in which one group of round belts is composed of two round belts, it may be constructed using a larger number of round belts.

As described above, in this invention, a first plurality of A plurality of round belts are stretched around each other, and a plurality of second round belts are stretched around the rollers on the destination side facing the conveying direction, and the state in which the first and second round belts are stretched around the rollers on the destination side is the same as that of the first and second round belts. Since the first group consisting of a plurality of round belts 4 and the second group consisting of a plurality of round belts are placed alternately, placing the object on the first plurality of round belts 4 makes it possible to It has the advantage of being able to sequentially convey the objects onto the second round belt.

Moreover, when conveying an object in this way, the object to be conveyed is a tile 5 having grooves 6 on the back surface.
Moreover, even if the round belt 4 sways horizontally during conveyance and the tile 5 comes close to the roller 1 on the destination side with the round belt 4 stuck in the groove 6, each group In this case, multiple round belts are arranged side by side, and when the round belt hung in one belt groove is pushed out from the belt groove by an external force, the round belt Since the belt is hung on the rollers on the destination side at such close intervals that the belt is in contact with the round belt hung on the adjacent belt groove and is prevented from being extruded from the belt groove, the round belt 4 is placed in the groove 6 on the back side of the tile. The lateral force applied to the round belt 4 as shown by the arrow A in FIG. It has the advantage of preventing accidents such as the belt 4 coming off from the belt groove 2 and becoming entangled with other belts.
