Description

[Detailed Description of the Invention] The present invention relates to a motor controller for a bowling machine that attempts to save power by stopping the motor of the bowling machine, which consumes a large amount of power, when unnecessary.

In recent years, we have entered an era in which energy conservation has become particularly important, and the bowling industry has been conducting studies across various fields, but with regard to electricity, the only thing that has been done is to adjust the lighting within the hall. However, the main culprits of the large amount of power consumption are the machine's motor, air conditioner, etc., and unless these consumptions are reduced, sufficient effectiveness cannot be achieved. Therefore, this project focused on the motor of a machine, which is a cause of mass consumption, and started research to save electricity by controlling it.First, we explained the conventional motor power supply circuit and motor operating status using drawings. do.

The motor power supply circuit 4, as shown in FIG.
The circuit configuration was such that when the 230V power switch 8 was turned on, the relays 9 and 10 were activated and the main motors, the tweezers motor 6 and the ball transport motor 7, were started.

As shown in A of Fig. 6, the motor operating state continues without stopping for both motors from the time when the front power switch 8 is turned on by applying for a game until the time when the power switch 8 is turned off by paying the game fee. 6 and 7 were in an operating state where they continued to rotate.

In other words, according to the conventional bowling machine, the tweezers motor 6 (230V - 6.8A) and the ball transport motor 7 (230V - 3.3A) are constantly rotating, which reduces the power consumption.
The power consumption was 2.5KW/h to 4KW/h, which was incomparably greater than the power consumption when some of the lights were turned off.

Therefore, in order to reduce the power consumption of the motor, the inventor investigated the actual operating state of the motor and found that the clutch engages only when the ball is pitched or when the reset button is pressed, and the motor performs its function. After discovering that the motor is idling at all other times, we focused on the actual operation of this motor and took into account our many years of experience with bowling machines to complete the motor controller of this invention.

The purpose of this proposal is to reduce power consumption caused by conventional idling by controlling the motor so that it rotates only when it is required to perform actual operation, thereby achieving various power savings. The object of the present invention is to provide a motor controller having advantages.

The gist of the motor controller of the present invention is that a control unit 3 is constructed from a timer 1 and a relay 2, and the unit 3 is connected to a clutch relay 5 incorporated in a power supply circuit 4 of the bowling machine. When the relay 5 closes, the timer switch 1a is turned on, the timer 1b is started, and the relay coil 2a is energized, and the opening/closing contacts 2b, 2b, 2b of the relay 2 are connected to the tweezers motor 6 and the ball conveyance terminal. At the same time as the clutch is activated, the motors 6, 7 are connected to the motor 7 and brought into operation by connecting the power supply circuit 4 and the control unit 3 as described above.
The reason lies in that the motors 6 and 7 are configured so that they are started and the motors 6 and 7 are stopped after the time set by the timer 1b has elapsed.

Next, the motor controller of the present invention will be described in detail below based on an example of implementation shown in the drawings.
First, as shown in FIGS. 1 and 2, the control unit 3 has a structure in which a timer 1 and a relay 2 are arranged in a box 11, and a terminal board 12 is provided.

The connection to the clutch relay 5 incorporated in the motor power supply circuit 4 of the bowling machine is made by connecting the clutch relay 5 and the cycle solenoid 16 through terminals 13, 14, and 15, as shown in FIG. However, the timer 1 and relay 2 of the control unit 3, which are the parts surrounded by dotted lines in FIG. 3, are formed to operate in conjunction with the clutch relay 5.

Next, the connection between the opening/closing contacts 2b, 2b of the relay 2 and the tweezers motor 6 is made by connecting the terminals 17, 18,
19 and 20 are used to connect the wiring to the motor 6, and terminals 21 and 22 are used to connect the opening/closing contact 2b of the relay 2 and the ball transport motor 7 to the wiring of the motor 7. Through these connections, the starting and stopping of the motors 6 and 7 are linked with the clutch relay 5. Further, although the set time of the timer 1 is set to 30 seconds in the embodiment, it is not limited to this time and may be set as appropriate.

In addition, what is indicated by 23 in the figure is an electromagnetic clutch, and 24
is a transformer, 25 is a pin finder, and 26 is a pin light.

Therefore, when installing the proposed controller, it is necessary to install the power supply circuit 4 of the existing bowling machine.
timer 1 and relay 2 without changing
The controller can be controlled simply by adding the control unit 3, which has a simple structure.

When bowling on the lane using the controller of the present invention, first, even if the power switch 8 is turned on, the opening/closing contacts 2b, 2b, 2b are in the open state, so the motors 6, 7 do not rotate.
Only the lamps are lit. When the ball is pitched, the power circuit of the clutch relay 5 is closed based on a signal detected by an optical sensor installed in the path of the pitched ball, and the relay 5 is closed.
When the power is turned on and the reset button is pressed,
Similarly, the power supply circuit of the clutch relay 5 is closed and the relay 5 is wired so as to be energized. Therefore, when the relay 5 is energized, the timer switch 1a is activated and the timer 1b is started, and the relay coil 2a is energized and the opening/closing contacts 2b, 2b, 2b are energized.
is closed, and the motors 6 and 7 are in a rotating state. Then, when the set time of the timer 1b has elapsed, the timer switch 1a opens, the relay coil 2a is no longer energized, the switching contacts 2b, 2b, 2b open and the motors 6, 7 stop. The above-mentioned operation is repeated for each pitch, and as long as pitches are made one after another normally within the time set by the timer 1b, the motors 6 and 7 remain in a rotating state.

In other words, if the instruction system by the controller of the present invention is explained with reference to the diagram shown in FIG. 5, it will be a system in which instructions are sent from the power supply circuit 4 to the motors 6 and 7 via the control unit 3 (solid line). The instruction system is significantly different from the system in which the instructions are directly sent to the motors 6 and 7 (indicated by dotted lines).

Next, the operating state of the motors 6 and 7 will be explained with reference to the drawing shown in FIG. The shaded area in Figure 6B is the time set for timer 1 (30 seconds) from the time of pitching (timer ON).
seconds) indicates the time period until the end (timer OFF).The upper part of the horizontal line indicates that the next pitch will occur after the previous pitch.
Indicates a case in which the pitch is made after 30 seconds have elapsed, during which time motors 6 and 7 will stop operating, but the next pitch will be made before 30 seconds have elapsed after the previous pitch, as shown at the bottom of the horizontal line. In this case, the operation of the motors 6 and 7 does not stop during that time, but operates continuously.

(1) Preparation time T1 of approximately 10 to 15 minutes from the time the game applicant turns on the power switch until the game applicant goes to the designated lane with the score sheet and throws the first pitch.

(2) Final time T2, approximately 10 minutes, from the time the timer has elapsed after the final pitch is made to end the game until the game fee is settled.

(3) Game interruption time T3 due to breaks for cigarettes, cola, restrooms, score collection, etc.

(4) Interruption time T3 due to inaccuracies in the location or pressing of the reset button and machine trouble.

(5) As a general rule, all machines are in operation during the tournament, and lanes where no pitching is being performed at this time.

(6) Time suspended for other reasons.

As described above, the motor controller of the present invention has a simple configuration in which the control unit 3 is incorporated into the existing power supply circuit 4, and the motor controller 6, 7
This has the effect of eliminating unnecessary idling and achieving significant power savings (15% to 20% according to experimental results).
