[Means for solving problems]

In order to solve the problem, the present invention provides a striking solenoid mechanism, a support, and a hammer mechanism for striking;
...... Tensioning springs ...... Adjustment stoppers ...... Returning movable shafts; Exciting the coil of the solenoid mechanism to hold the biasing position of the movable shafts, accelerating the hammer mechanism, And a control mechanism for controlling the end point of the stroke of the movable shaft by depressing the bell body and demagnetizing the coil to bring the rear end of the movable shaft into contact with the adjusting stopper to restore it. The present invention provides a striking device.

[Action]

Since the striking device of the present invention has the structure as described above, when the movable shaft of the solenoid mechanism is advanced, the relay is biased by a control command from the control mechanism to slide the shaft to pull the hammer mechanism. Accelerate to just before hitting the bell body against the spring, and hit it by inertia of the hammer mechanism. After that, when the hammer mechanism is returned by the spring force, the excitation of the relay is maintained on the movable shaft, so the hammer mechanism receives the hammer mechanism at that position and the bell body continues to ring. When the solenoid mechanism is de-energized, the movable shaft is returned by the spring force and comes into contact with the stopper so that the solenoid mechanism itself can be provided with a stopper facing the rear end of the shaft to prevent changes in the stroke end point of the shaft. It is a striking device.

Reference numeral 15 is a bracket made of L-shaped steel which is attached to the lower surface of the support plate 13 by bolts 16 and 16 which are screwed into the female screws 14 and 14, and a hole 17 formed in the horizontal portion 15 thereof is as shown in FIG. It is a long hole in the front-rear direction so that the mounting position can be adjusted.

Bearing stands 18, 18 are formed on the front end side of the vertical portion 20 of the bracket made of L-shaped steel. Further, a bush fixing hole 21 is formed in the vertical portion 20.

Reference numeral 22 denotes a solenoid mechanism in which the shaft 24 is inserted through the bush 23 fixed to the bush fixing hole 21 and the base side of the coil case 27 is fixed to the vertical portion 20. Inside the solenoid mechanism 22, an annular coil 25 and a guide cylinder that is inside thereof and forms a cylinder are fixed.

A movable iron core 26 is slidably fitted in the guide cylinder, and the shaft 24 is press-fitted and fixed to the center thereof. The coil case 27 is provided with a stopper 32 facing the rear end surface of the shaft 24.
Is screwed in and locked in the desired position with a lock nut.

A cable 28 is connected to the coil 25 from the outside through the hollow portion inside the holding cylinder 3 and the hole 12, and when energized, the coil 25 is excited and the movable iron core 26 and the shaft 24 hit the front base. Can be advanced at high speed. Reference numeral 29 is an elastic bullet-shaped head screwed into the front end of the shaft 24 and locked by a nut.

The shaft (24) and the movable iron core (26) integral with the shaft (24) are attracted rearward until they hit the stopper (32). However, when the coil 25 is not energized, the shaft 24 comes into contact with the front end of the stopper 32 locked at a desired position and stands still, which is the starting point of the shaft forward stroke due to coil excitation.

FIG. 4 is a striking device control circuit diagram for controlling the solenoid mechanism by turning on and off an exciting current for exciting the solenoid mechanism 22 at the moment of striking the solenoid mechanism 22, and (a) shows a control program recorded. A memory consisting of RAM and ROM that stores signal signals or performance data, (b) is a CPU that executes a control program, and (c) is a PIO that outputs the contents of external memory. Control line (d), address (e) , Connected by a data (f) bus to form a microprocessor. Noise isolation is performed on the output port (g) of the PIO (c) with a photocoupler (h).
The output drives the relay (j). Relay (j)
A coil 25 of a striking solenoid mechanism 22 and a DC power source (k) are connected in series to the secondary side of the. Therefore, the solenoid mechanism 22 is energized only when the relay (j) is energized in response to the output from the PIO (c).

FIG. 5 shows a data processing method on the circuit having the configuration of FIG. The data is stored in the memory (a) in the order of output, and the CPU (b) in the order of n-1, n, n + 1 at regular time intervals.
Read out to the output port (g). The output port (g) retains its contents until the next new data is transferred, and when the new data is transferred, the data of the port output (g) is updated.

Next, the operation sequence will be described in detail.

In the state of FIG. 1, when the output content Xo of the output port (g) of FIG. 4 changes for a fixed time t ₁ shown in FIG. 9, the signal causes the photocoupler (h) of FIG. 4 to change. The coil (25) of the solenoid mechanism (22) is excited by the relay (j) which is energized via. Then, as shown in Fig. 6, the shaft
24, the head 29 moves forward, swings the hammer 30 forward against the coil spring 37, and the rear end of the shaft 24 stops 32.
Leave.

Further, the shaft 24 moves forward and the movable iron core 26 hits the base of the solenoid mechanism 22 and stops as shown in FIG.
30 reaches the bell body 1 due to inertia and hits the bell.

However, immediately after that, the hammer 30 is slightly separated from the bell body at the position where it comes into contact with the head 29 at the forward end of the shaft 24 as shown in FIG. 8 due to the recoil of the bell and the restoring force of the coil spring 37, that is, at the midpoint of FIG. , The bell body does not come into contact with the continuous vibration and does not damp the vibration, and the shaft 24 moves from the stopper to the hammer 30 when the movable iron core of the excited solenoid mechanism 22 hits the base. Even if the shaft slightly moves, it returns to a position where it does not come in contact and stops. In addition, until after hitting the hammer again after hitting the hammer,
The hammer 30 is in a state in which nothing is in contact with anything other than the supporting pin 33. At this time, since the coil 25 is still in the excited state, the movable iron core 26 and the shaft 24 are held at the forward end by the magnetic force. Therefore, the reaction of the hammer 30 is attached to the movable iron core 26 which is abutted against the base in the excited state. The head 29 contacts the arm 31 of the hammer and directly supports it by magnetic force without mechanically supporting it.The strong and short reaction component is generated as a holding current by the movable iron core 26 slightly retracting and returning due to the collision of the head 29. Can absorb and receive energy. After a desired time, when the relay (j) in FIG. 4 is deenergized and the coil excitation state of the solenoid mechanism 22 is canceled, the hammer 30 causes the coil spring 37 to move the shaft 2
4. The movable iron core 26 is attracted rearward, and the rear end of the shaft 24 abuts against the stopper 32 as shown in FIG.

This position is also the starting point for the striking stroke.
