Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a ball stopping mechanism for a pachinko ball lifting device that polishes dirty pachinko balls with abrasive grains such as synthetic resin while stirring and transporting them. In particular, the present invention relates to a manual ball stopper mechanism that shuts off and opens at a ball inlet, which does not get jammed when the ball is shut off and can easily maintain or release the closed state.

(Prior art) Conventionally, the ball stopper mechanism used when exchanging abrasive grains or cleaning abrasive grains is located near a ball inlet that is connected to the sloping lower end of a collection gutter that collects pachinko balls discharged from each pachinko machine. Vertical slits are formed on both sides of the collection gutter, and a partition plate is inserted into the slit to stop the pachinko balls from flowing into the ball inlet, thereby allowing the pachinko balls to remain on the collection gutter. is disclosed.

(Problem to be solved by the invention) However, in the conventional mechanism, a partition plate is inserted and sandwiched between two places on the left and right sides of the ball inflow port on the collection gutter near the ball inflow port, and the partition plate is rolled from both the left and right sides. Since each pachinko ball that comes to the machine has to be blocked separately, the work has to be done in two places, which is a problem in that it takes time and effort to work in narrow and hard-to-reach places.

This invention circulates and uses abrasive grains to clean and polish pachinko balls, but when the abrasive grains themselves become dirty, or when the abrasive grains themselves become smaller due to the abrasive grain cleaning device, they are replaced with new abrasive grains. When replacing the pachinko balls or cleaning the abrasive grains, the pachinko ball stopping mechanism (operation) can be done in one place, and there is no jamming when the balls are cut off, and the cut-off state can be easily maintained or released. The object of the present invention is to provide a locking mechanism.

(Means for Solving the Problems) In order to achieve this purpose, the present invention opens a ball inlet through which pachinko balls discharged from a pachinko machine flow into a pipe, and mixes and stirs the pachinko balls with abrasive grains. The pachinko ball lifting device lifts the balls while polishing them, and the manual ball stopper plate that opens and blocks the ball inflow port is formed with approximately the same width as the ball inflow port, and has a bent piece at the lower end. A vertically elongated hole is bored in the center, and the ball stopper plate is sandwiched between the outer cylinder mounting body and the plate receiving plate and is configured to slide along the pin. When the bent piece is raised from below, it rises along the pin and hits the fixed member fixed to the plate receiving plate, keeping the flow to the ball inlet blocked, and further polishing and lifting of the pachinko balls. When the ball stopper plate releases the bent piece from the fixing member, it descends along the pin and locks at the end of the vertical hole, opening the ball inflow into the ball inlet. It is characterized by a stop mechanism.

Further, the fixing member for raising the ball stopper plate of the ball stopper mechanism and maintaining the blocking state is a magnet.

(Function) The ball stopping mechanism of the pachinko ball lifting device is used when the abrasive grains themselves that polish the pachinko balls become dirty, or when the abrasive grains themselves become dirty if the device is not equipped with an abrasive grain cleaning device. If the abrasive grains themselves become small due to the cleaning device, it is necessary to replace them with new abrasive grains. At this time, the purpose is to prevent pachinko balls from flowing into the abrasive grain cleaning device of the pachinko ball lifting device equipped with the abrasive grain cleaning device.

In the manual ball stop mechanism of the present invention, when the bent piece of the ball stop plate provided at the ball inlet is lifted from below, it rises along the pin and hits the fixing member on the back of the plate receiving plate, causing it to be in a blocking state. is maintained and the inflow is blocked (see Figure 1).

Further, when the bent piece of the ball stopper plate is pushed down, the contact with the fixing member is released and the ball moves down along the pin, opening the ball inlet and allowing the pachinko balls to flow in (see Fig. 2).

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings. First, a pachinko ball lifting device A equipped with the ball stopping mechanism of the present invention will be explained.

As shown in Figure 4A, the pachinko ball transport device A is installed in the center of an island that constitutes a row of pachinko machines in which multiple pachinko machines are arranged side by side, and collects the pachinko balls (out balls) discharged from each pachinko machine. It is collected in gutter 1 and polished.

A lift pipe 4 is erected on a transfer pipe 3 connected to the ball inflow port 2, and a transfer spiral body 3b which is rotated by the drive of a transfer motor 3a is provided inside the transfer pipe 3. Lifting motor 4
A lifting spiral body 4b that rotates when driven by a is provided inside.

A sorting device 6 is provided that mixes and agitates pachinko balls and abrasive grains while polishing them, lifts them, and sorts the mixture discharged from the upper discharge port 5 of the lifting pipe 3 into pachinko balls and abrasive grains. Inside the device 6, the gap is larger than the outer diameter of the abrasive grains, and the separation gutter 9 for the balls, which is smaller than the pachinko balls, is slightly inclined downward, and the upper end of the slope is connected to the discharge port 5, and the separation gutter 9 separates the particles. The rolled pachinko balls fall onto the supply gutter 9a and are supplied to the left and right pachinko machines.

The abrasive grains are normally supplied again into the transfer pipe 3 through an abrasive grain circulation hose 10 that connects the sorting device 6 and the transfer pipe 3, and are reused.

In addition, the separation gutter 9 in the form of a screen is 2 as shown in Fig. 4B.
It is formed in a step and is connected to the discharge port 5 with a step difference.

Furthermore, a lid 7 is attached to the upper surface of the upper sorting device 6 to prevent dust from entering from the outside (particularly dust adhering to the lift motor 4a) and to prevent the sorting device 6 from getting mixed with dust.
By sealing the area, the ability of the dust collector 8 to collect polishing dust is increased.

Polishing dust generated when the mixture is discharged or separated in the sorting device 6 is sucked by a dust collection hose 8a connected to a dust collector 8 and stored in a dust collection tank 8b.

In addition, when the abrasive grains become dirty after being reused several times, the abrasive grains are branched by a switching shutter (not shown) provided in the middle of the abrasive grain circulation hose 10 and sent to the abrasive grain cleaning device 12 from the abrasive grain cleaning path 11. The surface of the pipe is peeled off to remove dirt and returned to the transfer pipe 3.

Incidentally, the dirt of the abrasive particles removed by the abrasive particle cleaning device 12 is stored in an abrasive particle dust collection box 12a, and is configured so as to be appropriately disposed of outside.

Next, the ball guide plate 20 shown in FIG. The ball guide plate 20 is configured to be able to adjust its position in the longitudinal direction of the adjustment hole 22, and the ball guide plate 20 is inclined toward the inlet 2 between the tip molds by 20a and 20b. It is formed in a V shape, and guides pachinko balls rolling through pachinko ball collecting troughs 1 on both sides to a ball inlet 2.

If this ball guide plate 20 were not provided, the pachinko balls rolling from the collection gutter 1 on both sides would hit each other in front of the ball inlet 2 and would not be guided smoothly into the ball inlet 2. At the same time, when the amount of pachinko balls discharged from the pachinko machine and rolling through the collection gutter 1 is different on the left and right sides, the ball guide plate 20 is arranged so that the side with a high flow rate of pachinko balls is wide open and the side with a low flow rate is narrow. is slid and engaged on the side where the flow rate is low, allowing the pachinko balls flowing into the ball inlet 2 to roll smoothly.

Next, the manual ball stopping mechanism which is the gist of the present invention will be explained with reference to Figs. 1 and 2. As explained above, the abrasive grains for polishing pachinko balls are reused. In the case where the abrasive grain cleaning device 12 is not equipped, when the abrasive grains themselves become dirty, and in the case where the abrasive grain cleaning device 12 is equipped as in the present invention, the abrasive grains are removed. When the function no longer works (when the abrasive particles become smaller due to the abrasive particle cleaning device 12),
Each abrasive grain needs to be replaced with a new abrasive grain, and this is to reliably prevent pachinko balls from flowing into the pachinko ball transport device A when cleaning the abrasive grains.

A ball inlet 2 through which pachinko balls flow into the gap between the collection gutter 1 and the transfer pipe 3 is opened, and a ball stopper plate 32 that opens and blocks the ball inlet 2 is connected to the ball inlet 2.
A bent piece 3 formed with approximately the same width and bent at the lower end.
2b, and a vertically elongated hole 32a is bored in the center.
1a).
The ball stopper plate 32 is held between an L-shaped plate receiving plate 31 on the front side and an outer cylinder mounting body 30 on the rear side.

A pin 33 is bored in the front plate receiving plate 31, and a magnet 31a, which is a fixing member that comes into contact with the bent piece 32b of the ball stopper plate 32, is attached to the horizontal portion. Pin 3 of the plate receiving plate 31
3 is configured to move up and down (slide) within the vertically elongated hole 32a, and has a ball stopper mechanism. Although the fixing member is the magnet 31a here, it is not limited to this.

When replacing the abrasive grains or cleaning the abrasive grains, as shown in Figure 1, the ball stopper plate 3
When the bent piece 32b of 2 is lifted from below, the pin 3
3 and hits the magnet 31a to close the ball inlet 2, thereby blocking the inflow of pachinko balls discharged from the pachinko machine. At this time, the bent piece 32b of the ball stopper plate 32 is connected to the magnet 3.
1a, the blocking state is maintained to prevent the ball stopper plate 32 from falling by itself.

At this time, when replacing the abrasive grains, use the lifting pipe 4.
By rotating the transfer spiral body 3b and the lifting spiral body 4b, the abrasive grains are lifted up through the abrasive grain collection port 13a provided on the side surface of the abrasive grains, and are discharged from the collection port 13a. The abrasive grains at the corners are taken out from the abrasive grain collection port 13b provided at the lower end of the transport pipe 4.

After the abrasive grains present in the transfer pipe 3 and the lifting pipe 4 are discharged in this way, new abrasive grains are added to the inlet 1 provided in the lower part of the abrasive grain circulation hose 10.
Add abrasive grains from step 4.

Next, when opening the ball stopper plate 32 of the ball inflow port 2 and letting the balls flow in, push down the bent piece 32b, and the balls will descend along the vertical hole 32a formed in the center of the ball stopper plate 32, and the balls will flow in from the magnet 31a. The bent pieces 32b are separated and released, and the pachinko balls discharged from each pachinko machine sequentially flow into the ball inflow port 2 and into the transfer pipe 3.

The pin 33 is locked at the end of the vertical hole 32a at the lowered point pushed down by the ball stopper plate 32 to prevent it from lowering any further.

(Effect of the invention) As is clear from the above explanation, the manual ball stopper mechanism of the present invention has a mechanism in which the bent piece of the ball stopper plate is lifted from below when blocking the ball inlet. To cut off accumulated pachinko balls without biting them. As a result, it is a mechanism in which there is no failure due to jamming during shutoff, and when it is further raised, it comes into contact with a fixed member and has the effect of maintaining the shutoff state. In addition, it is also a mechanism that can easily release the shut-off state.

In addition, the ball fixing work, which conventionally had to be done at two locations, can now be done at one location at the ball inlet, which has the effect of shortening the work time and also eliminates dirty abrasive grains and their functions. Because it can be easily extracted, it reduces the labor of store staff and contributes greatly to the industry.
