Description

Mahjong machine licensing agency

The present invention relates to a transmission mechanism, in particular to a Mahjong machine card raising mechanism.

Mahjong machine, as a kind of mass entertainment products, can manage cards and shuffle automatically. The main principle is that the mahjong washed in the shuffle bucket is transported to the four-way jigsaw jacks through a conveyor belt, and is driven to the table of the automatic mahjong machine under the driving of the Mahjong machine's card raising mechanism.

At present, the main structure of the existing card-raising mechanism includes an arc-shaped product card holder, a push rod and a rocker. One end of the rocker is opposite to one end of the product card holder. After the system detects Mahjong on the product card holder, The motor drives the push rod to rotate in the circumferential direction. The push mahjong moves forward on the arc-shaped track of the jackpot and enters the rocker. When the system detects that the Mahjong has completely entered the rocker, the motor controls the push rod to stop rotating, The rocker is moved upward by another motor, so that the mahjong card is placed in a horizontal position. After the system detects that the mahjong card is completely horizontal, it stops moving and waits for the next round of work. However, this kind of Mahjong machine brand promotion mechanism still has the following problems: the positions of the different moving nodes of the Mahjong card need to be detected by high-precision sensors, and the rocker and the push rod are driven by a plurality of independent motors. Each of the rising agencies requires multiple motors and multiple sensors, which has a high production cost. As the electronic components, the sensors are more likely to be damaged than the mechanical mechanisms. Too many sensors require a large number of connecting wires, which easily cause safety problems, stability and stability. Low reliability.

Therefore, the object of the present invention is to provide a mahjong machine raising mechanism which can reduce the failure rate and reduce the production cost.

Therefore, the new Mahjong machine raising mechanism is applicable to a mahjong machine frame and a plurality of Mahjong tiles. The Mahjong machine raising mechanism includes a jack, a rocker, a push rod, a driving motor, and a driving gear. , A driven gear, a cam mechanism, and a position sensor.

The jack stack defines a circular arc-shaped slot for receiving the Mahjong cards. The slot has an input terminal and an output terminal opposite to each other. The rocker corresponds to the output end of the card slot. The push stick is used to push the Mahjong tiles. The driving motor is disposed at the center of the jackboard, and the driving motor includes an output shaft.

The driving gear is sleeved on the output shaft and is driven by the driving motor. The driving gear includes a gap. The driven gear partially engages the driving gear. The driven gear and the driving gear disengage at the gap. The gear includes a connecting portion that extends upward and connects one end of the push rod. The cam mechanism is disposed between the driving gear and the rocker and is driven by the driving gear to swing the rocker up and down. The position sensor is disposed on The driven gear is also used to sense the position of the driven gear.

The effect of the novel model is that multiple electronic components are replaced by the combination of the driving gear, the driven gear and the cam mechanism, and only one driving motor is needed to control the rocker and the push rod, which not only reduces Failure rates can also reduce production costs.

Referring to FIG. 1, FIG. 2, and FIG. 3, an embodiment of the new Mahjong machine brand promotion mechanism is applicable to a mahjong machine frame (not shown), and a plurality of mahjong cards (not shown). Including a dovetail slot (not shown), the Mahjong machine card raising mechanism includes a jackpot 1, a rocker 2, a push rod 3, a driving motor 4, a driving gear 5, a driven gear 6, The cam mechanism 7, a position sensor 8, and a limit plate unit 9.

The jackpot 1 defines a circular arc-shaped slot 11 for receiving the Mahjong cards. The jackpot 1 further includes an arc that communicates with the slot 11 and corresponds to the slot 11. The track 12 has a trapezoidal protrusion 13 provided on the outer surface and capable of slidingly engaging with the dovetail slot. The card slot 11 has an input end 111 and an output end 112 which are oppositely arranged.

One end of the rocker 2 corresponds to the output end 112 of the card slot 11 and can be driven to swing up and down.

The pushing rod 3 is used to push the Mahjong tiles. The pushing rod 3 has a pushing portion 31 provided at an end far from the driven gear 6. The pushing portion 31 can extend into the arc-shaped track 12 and be connected with the circle. The curved rails 12 cooperate.

The driving motor 4 is disposed at the center of the jack stand 1. The driving motor 4 includes an output shaft 41.

The driving gear 5 is sleeved on the output shaft 41 and is driven by the driving motor 4. The driving gear 5 includes a notch 51.

Referring to FIGS. 1, 4 and 5, the driven gear 6 partially engages the driving gear 5. The driven gear 6 and the driving gear 5 are disengaged at the gap 51. The driven gear 6 includes an upwardly extending and A connecting portion 61 connected to one end of the pushing rod 3, and a sensing portion 62 extending outward in the radial direction of the connecting portion 61. The sensing portion 62 has a central hole 621 at the center of the sensing portion 62, and an embedded portion The central hole 621 is a magnetic block 622 (see FIG. 5) for the position sensor 8 to sense.

Referring to FIGS. 1, 3 and 4, the cam mechanism 7 is disposed between the driving gear 5 and the rocker 2 and is driven by the driving gear 5 to swing the rocker 2 up and down. The cam mechanism 7 includes a recess A track groove 71 provided on the bottom surface of the driving gear 5, a connecting rod 72 connected to the driving gear 5 and driven by the driving gear 5, a jack 73 connected between the rocker 2 and the connecting rod 72, a A slider 74 disposed on an end of the connecting rod 72 adjacent to the driving gear 5 and extending upward into the track groove 71 and a rack 75 disposed on an end of the connecting rod 72 away from the slider 74 and facing upward, The ejector rod 73 has a gear portion 731 disposed at the lower end and meshing with the rack 75. An end of the ejector rod 73 opposite to the gear portion 731 abuts the rocker 2.

The limit plate unit 9 is connected to the rocker 2. The limit plate unit 9 includes an inner limit plate 91 disposed on a side of the rocker 2 adjacent to the driving gear 5 and perpendicular to the rocker 2, and The outer limit plate 92 opposite to the inner limit plate 91 has a groove 911 for the push portion 31 of the push rod 3 to pass through.

During operation, the Mahjong cards enter the card slot 11 from the input terminal 111, the driving motor 4 rotates to drive the driving gear 5 and then the driven gear 6, and drives the push rod 3 to rotate in the circumferential direction to push the Mahjong cards. Move along the arc-shaped card slot 11 toward the seesaw 2 at this time, the seesaw 2 is in contact with the output end 112 at an angle, and when the Mahjong tiles are completely moved on the seesaw 2 Since the notch 51 of the driving gear 5 does not have a tooth shape, it does not mesh with the driven gear 6 and disengages each other. Therefore, the driving gear 5 cannot drive the driven gear 6 when the driving gear 5 rotates, thereby preventing the push rod 3 from moving forward. When it is in conflict with the rocker 2, at this time, the driving gear 5 continues to rotate so that the track groove 71 links the slider 74 and the connecting rod 72, and the rack 75 moves with the connecting rod 72 while also The gear portion 731 drives the ejector rod 73, and the ejector rod 73 drives the end of the rocker 2 adjacent to the output end 112 to swing upward until the rocker 2 is horizontal, so that the mahjong cards are horizontally placed on the table, and then , The meshing position of the driving gear 5 and the driven gear 6 has been changed from that The port 51 is rotated to a toothed position, and the driven gear 6 continues to rotate to drive the pushing portion 31 through the groove 911 (see FIG. 2). When the rocker 2 is raised to the highest position, the driven gear 6 is below The magnetic sensor 622 is sensed by the position sensor 9, and the system stops moving and waits for the next round of work.

Compared with the prior art, the new type can control the pushing and stopping of the push rod 3 through the combination of the driving gear 5 and the driven gear 6, and the cam mechanism 7 can control the rocker 2 to rise and fall periodically. These two intermittent motion mechanisms can control the movement of the push lever 3 and the rocker 2 when the Mahjong tiles are in different positions. The mechanical structure has been used to replace multiple position sensors 8. Therefore, many electronic components are reduced, and the reliability is higher. It is not easy to be damaged, and the cam mechanism 7 is linked with the same driving gear 5 so that only one driving motor 4 is needed to control the rocker 2 and the push rod 3, which greatly reduces the production cost.

Referring to FIG. 1, FIG. 2 and FIG. 6, in addition, the present invention also cooperates with the dovetail groove of the mahjong machine frame by the trapezoidal protrusion 13 (see FIG. 6) of the jackpot 1 to make the structure more It is stable and easy to locate, and guides the push rod 3 through the arc-shaped track 12 to make the Mahjong cards more stable when pushed.

To sum up, the new Mahjong machine brand raising mechanism replaces multiple electronic components by the combination of the driving gear 5, the driven gear 6, and the cam mechanism 7, and only needs one driving motor 4 to control the The rocker 2 and the push rod 3 can not only reduce the failure rate, but also reduce the production cost, so it can indeed achieve the purpose of new cost.
