Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an apparatus arranged in a tile manufacturing line, in which a tile row in which a plurality of tiles are aligned is placed on a tile unloading conveyor, The present invention relates to a tile row transfer device that transfers a tile row so that the row direction is a direction transverse to the traveling direction of the tile carry-out conveyor.

In the present specification, the tile refers to a tile raw material before calcination,
Glazed tile base before main firing or tile after main firing (for example, 98 x 98 x 5 mm).

[Prior Art] Conventionally, as a transfer device for a tile row, as shown in FIG. 7, a tile carry-in conveyor 1 including a belt belt extending in the front-rear direction and a tile carry-in conveyor 1 ascending / descending on both left and right outer sides. And tile supporting surface portions 2a, 2a, ..., and an aligned tile lifting tool 2 in which a plurality of pressing hook passages 2b which are recessed from the height position of the tile supporting surface portion 2a and which are long in the left-right direction are appropriately formed for each front and rear pitch, The tile unloading conveyor 3 extending from one side of the loading conveyor 1 in the left-right direction, and a plurality of pushing hooks 4a for pushing the tile row T lifted by the aligned tile lifting tool 2 onto the tile unloading conveyor 3 for each predetermined pitch. The pushing tool 4 thus formed is provided. The tile row T lifted by the aligned tile lifting tool 2 after being aligned on the tile carry-in conveyor 1 is pushed in with the lower surface one side edge Ta hooked by the push-in hook 4a of the push-in tool 4, and the tile carry-in conveyor. 3 is transferred.

[Problems to be Solved by the Invention] However, the conventional tile-row transfer device has the following problems.

(a) Since the tile rows T can be transferred only one by one, the tile transfer processing amount per unit time is small.

(b) In order to increase the tile transfer processing amount, it is necessary to increase the loading speed of the tile loading conveyor 1 and the pushing speed of the pushing tool 4. However, since the transferred tiles t are easily damaged, there is a limit to increasing these speeds.

(c) Since the transfer of the tile row T is forced pressing by the pressing tool 4, the corners and the like of the tile t may be lost during the transfer. Therefore, the conventional device has reduced the yield of the tile manufacturing line.
