2. Description of the Related Art In a process of sequentially conveying a set of tiles arranged in a grid pattern on a conveyor, the direction is changed from the end of one process to the start of another process due to space and work relationships. May be reprinted. For example, as shown in FIGS. 4 and 5, the conveyor 1 and the conveyor 2 are arranged at an angle of 90 degrees, and the tiles 3 ... The items arranged in a line are conveyed as a set S, and
When reaching the end of the conveyor 1, the suction-type transfer device transfers the transfer to the start of the next conveyor 2 and changes the transfer direction. The suction type transfer device is capable of transferring two sets at a time, and the adsorbents 4 and 4 are arranged side by side in the transfer direction of the conveyor 1, and a hose 6 is connected between the adsorbents 4 and 4 and the suction device 5. The switching valve 7 is provided on the suction device 5 side of the hose 6.

4 and the suction plate 4 has a suction cup 4a.
.. are arranged in the same manner as the tiles 3.

[0003]

However, there is no problem if one set of tiles conveyed on the conveyor 1 is complete, but if there are occasional omissions in the manufacturing process, the conveyance will be hindered. It occurs. That is, even if about 50% of one adsorbent 4 is missing, tiles 3 ...
, Are sucked by the suction cups 4a, 4a, ... For example, even if it is once adsorbed, the tiles fall apart due to shocks such as when the adsorbent 4 starts to move up and down, when it stops, and when it starts and stops laterally, and the tiles fall apart and on the conveyors 1.2 and on the conveyors 1.2. It had fallen onto the tiles before and after the transportation, causing breakage. Also,
Since there is only one switching valve for the two hoses, if a tile falls from one of the adsorbents, the suction force of the other adsorbent will also decrease and the tiles that have been adsorbed will also fall. It was. Therefore, if they were not conveyed neatly on the conveyor 2, trouble would occur in the boxing device in the next step.

[0004]

In order to solve such a problem, the present invention has a plurality of adsorption systems, and simultaneously adsorbs a plurality of conveyed products to each of the adsorption systems so that a secondary conveyor can be used. In the mechanism for adsorbing and conveying to the next conveyor, the missing detection sensor is arranged on the primary conveyor to detect the missing state of the conveyed product in each adsorption system, and if the conveyed product is missing more than the set value, the adsorption system It is configured to stop the adsorption.

[0005]

When a plurality of tiles 3, 3, ... Which are objects to be conveyed are arranged in a grid pattern and conveyed as one set S one after another on the primary conveyor 10, the missing detection sensor 3
At 0, a missing state is detected for each set, and if more than a set value is missing, the switching valve on the side of the adsorbent 13 that adsorbs the tiles of that set is switched to stop the aspiration and set the omission. If it is within the value, the adsorbent body 13
The tiles that have been adsorbed by and are conveyed from the end of the primary conveyor 10 to the beginning of the secondary conveyor 11, and the tiles that were not adsorbed due to the large number of missing tiles are collected from the end of the primary conveyor 10
It falls into 2 and is collected.
