waiting for the next tile to be picked up.

In another embodiment of the invention, the height of the card inlet of the card storage slot is lower than the height of the card outlet of the card delivery device and the difference M between the heights of the two is less than the height of one mahjong card, preferably 1 to 13 cm. The card pushing process is as follows: the card receiving block 401 receives a first mahjong card 10 at an initial position slightly lower than the card outlet of the card sending device; then descending a height to receive a second mahjong tile; then the card bearing block 401 rises to the initial position, and the height of the card bearing block is close to that of the card inlet of the card storage groove; the stacked mahjong tiles are pushed into the tile inlet of the tile storage groove 502 by the tile pushing head 501, and after the tile pushing head 501 retreats, the next mahjong tile is waited to be connected.

During the stacking process of the mahjong machine, the playing of the tile conveying device can be controlled by controlling the start and stop of a conveyor belt in the tile conveying device, the playing of the tile conveying device can be controlled by blocking a tile outlet of the tile conveying device by a tile pushing head 501 or a tile feeding driving mechanism (such as a tile pushing swing rod 503) and matching with a stacking signal, or a blocking device for preventing the tile conveying device from conveying mahjong tiles is arranged on the tile conveying device. The blocking device can be arranged at a card outlet of the card sending device, such as a blocking component disclosed in patent document with the publication number of CN 205964958U; the blocking device can also be a card-feeding assembly which is arranged at the card inlet or inside the card-feeding device, such as a card-feeding assembly disclosed in the publication No. CN103157278A and an electrically-controlled gate disclosed in the publication No. CN 204601595U.

The mahjong tile stacking method comprises the following steps: 1) the card bearing block stays at a first height which is lower than the height of the card outlet of the card sending device, and bears a first mahjong card sent from the card sending device; 2) after the tile conveying detection device detects that the first tile is in place, the stacking and pushing driving mechanism drives the tile bearing block to descend and stay at a second height, at the moment, the top surface of the first tile on the tile bearing block is lower than the tile outlet of the tile conveying device, the tile bearing block bears a second tile conveyed from the tile conveying channel, and the second tile is stacked on the first tile; 3) after detecting that the second mahjong tile is in place, the stacking and pushing driving mechanism drives the tile pushing head to push the stacked mahjong tiles into the tile storage groove; 4) the card bearing block and the card pushing head are reset to the initial positions.

A mahjong stacking process of the mahjong machine is described in the following with reference to the attached drawings 4-13: when the card folding is not started, the card pushing head 501 or the card pushing swing rod 503 completely or partially blocks the card outlet of the card sending channel to wait for the card folding signal, as shown in fig. 4 and 5; when the mahjong machine receives the stacking signal, the tile pushing head 501 rotates to the tile outlet of the tile sending channel, and the tile sending device sends the first mahjong tile to the tile bearing block 401, as shown in fig. 6 and 7; when the card delivery detection device 411 detects that the first card is in place, the card support block 401 descends to a second height to support a second card, as shown in fig. 8-11; then, the stacking and pushing driving mechanism drives the tile pushing head 501 to push a pile of mahjong tiles on the tile bearing block 401 into the tile storage groove, and the tile bearing block and the tile pushing head are reset to wait for the next stacking and pushing action, as shown in fig. 12 and 13.

The same set of stacking driving mechanisms as shown in the attached figures 4-13 are used, and the stacking process is different according to the initial position of the card pushing head: the initial position of the card pushing head gives way to a card outlet of the card sending device, the card bearing block stays at a first height, and the card sending device directly sends a first card to the card bearing block; when the mahjong machine receives the mahjong stacking signal, the mahjong bearing block descends to a second height to bear a second mahjong tile sent out from the mahjong sending channel, after the fact that the second mahjong tile is in place is detected, the mahjong pushing head pushes a pile of mahjong tiles on the mahjong bearing block into the mahjong storage groove, the mahjong bearing block and the mahjong pushing head reset, in the process that the mahjong bearing block resets to the first height, the mahjong pushing head retreats to block a mahjong tile outlet of the mahjong sending device and prevent the mahjong tile sending device from sending the mahjong tile, and after the mahjong bearing block resets to the first height, the mahjong pushing head completely lets out the mahjong tile outlet of the mahjong sending device. The mahjong tiles sent to the tile bearing block can be arranged in order.

In the two embodiments, the mahjong pushing head or the mahjong loading driving mechanism blocks the mahjong outlet of the mahjong conveying device to limit the mahjong discharging of the mahjong conveying device, so that the control of the motor in the mahjong machine can be simplified, and the error rate caused by frequent electric control can be reduced.
