(Effects of the Invention) As described above, the mahjong tile conveying device of the automatic mahjong table of the present invention has the following features:
An endless chain with four carry pins (first, second, third, and fourth) set up in predetermined positions for transferring tiles is passed through the guide groove of the transfer path and carried onto the upper side of the chain.・P/
The tile-building transfer mechanism is equipped with a rack so that it protrudes, and the two-tier horizontal legs are elastically pushed out one pair at a time by a pusher toward the waiting table in the east area, and the number of legs set in advance for the game is built. The endless chain, which rotates each time the chain is moved, moves the tiles for Nanyo to the standby table in the south field using the first carry-by placed upright on the chain, and forces it with the second carry-by. The tiles for the hall are transferred to the waiting stand in the west area, the third carry bin is used to transfer the tiles for the second area to the waiting stand for the second area, and finally the fourth carry bin is used to transport the tiles for the landing area. Transfer the tiles to the waiting table in the east area. At this time, the four rotating endless chains move the tiles for each part at the same time, and control the tile transfer to accurately position them in the opposite position of the winter elevator that is waiting at the fixed position. Since it consists of a processing means, its effect is that it does not reduce the setting speed of the two-stage stacked tiles (on the contrary, it is possible to shorten the setting time by increasing the extrusion speed with the pusher, and the extrusion speed is reduced. It absorbs overruns caused by elastic elements that could otherwise occur, and has the effect of filling in the gaps caused by them, so that the last pair of tiles, which had previously been particularly pointed out, can be placed on the elevator or on the east field. There is an entrance for a two-stage horizontal leg in the opening provided at one corner of the tile transfer path where the rear end of the waiting table intersects with the tip of the southern waiting table. A two-tier lateral leg counting sensor is installed to detect each set of two-tier lateral legs being pushed in, and the value detected and counted by the two-tier stacking counting sensor must match the preset game specification value. This device constitutes a tile building counting processing means using a two-stage stacked tile counting unit that completes the building of tiles on the two-stage horizontal leg.
A position sensor is set at the final end position of a built tile that is pushed in with a push button.This is due to overruns and gaps between tiles that can occur with the conventional method of detecting the distance between built tiles that have already been stacked in two levels. This device has the effect of completely eliminating problems such as counting errors due to misalignment and malfunctions caused by adhesion of dust and other foreign matter.
