The present invention relates to a curing coefficient stop device of a curing treatment machine such as a curing counter, a curing classifier, a curing packaging machine and the like.

More specifically, the present invention relates to a hardening coefficient stop device of a hardening machine in which hardening is conveyed and counted in the hardening passage and the subsequent hardening is stopped when the predetermined number of hardening is counted.

In a conventional hardening apparatus, a counter working in conjunction with a star wheel has been used to count hardening. If this star gear has a gear, the structure of each gear will be equipped with the peripheral surface of hardening.

The hardening is counted each time the star gear is rotated by one tooth for each hardening.

However, in the case where the counting operation is performed at a high speed, the above counting system may cause excess coefficients due to the large inertia of the star gear when the star gear is stopped in accordance with the counting end signal, thereby causing the star gear to rotate more and not stop at the predetermined position. It has the disadvantage of causing malfunction.

In another conventional hardening apparatus, the counting operation is performed by having a roller that engages the curing each time the curing passes.

However, in these machines, the disadvantage that the roller stops the hardening which forms the whole arm and the gun operated by the electromagnet, and the stop action cannot be performed quickly due to the inertial force of the stopper with the roller and the arm. have.

In addition to the machines described above, another apparatus for curing stoppers has been proposed. In one conventional stopper device, hardening is stopped by a stopper rod projecting from one side of the hardening passage to the hardening passage, and in the other stopper device, hardening is performed by a stopper rod projecting upward from the bottom of the hardening passage. Is stopped.

In the former device, the stopper rod protrudes into a coarse triangular space in a passage formed by both peripheral surfaces of two hardening adjacent to the guide plate. Since the triangular space is relatively large, the timing for actuating the stopper rod can be set within a relatively long period of time. However, since the hardening is forced to move at high speed by the conveying belt, when hardening is stopped, the stopper rod and / or subsequent hardening may be impacted or reversed, resulting in overlapping of the hardened hardening.

In order for the stopper rod to withstand impact, the stopper rod must be made large and rigid. Also in such a case, the force for operating the stopper rod must be large.

As such, it has the drawback that the entire stopper must be manufactured with a relatively large mechanical force and the machine itself becomes complicated.

In the latter arrangement, the position at which the stopper rod protrudes upwards must be set near the contacts of two adjacent hardenings in order to obtain static accuracy. In this case, the time at which the stopper protrudes must be correct. If the stopper rod protrudes out of time, the conveying belt will be lifted as the guide plate forming the hardening passage is greatly pushed or the hardening is heard.

Thus, the hardening so heard will be forced to be carried by the conveying belt without being counted and therefore the uncounting curing will pass.

Therefore, the first object of the present invention is to provide a novel hardening coefficient stop device for a hardening machine which solves the above-mentioned drawbacks.

A second object of the present invention is to provide a hardening coefficient stopper with a stopper that is simple in structure and very easy to operate.

It is a third object of the present invention to provide a cure count stop device with a counting device without mistake in cure.

It is a fourth object of the present invention to provide a hardening coefficient stop device which does not perform wrong counting when the hardening machine is manufactured.

According to the present invention, there is provided a hardening coefficient stop device of a hardening treatment device, wherein the hardening conveyed in the hardening passage is counted in turn and stopped when the predetermined number of hardenings is counted, the device being hardened to detect the hardening passage to generate a signal. A stopper and signal to stop the curing when the stopper is rotated by having at least one sensor in the passage and a rotating material which is installed next to the above-mentioned detector and protrudes into the curing passage, to signal that the predetermined number of curing has been counted. An apparatus for rotating the stopper is provided.

Other objects and advantages of the present invention will become apparent from the following with reference to the accompanying drawings.

Embodiments of the present invention will now be described with reference to the drawings.

1 shows a curing coefficient stop device of the coin processing machine according to the present invention.

The hardening 10 supplied onto the rotating disc 11 is received in a row as a hardening passage 12 formed by the fixed guide plate 14 and the moving guide plate 15 as the rotating disc 11 rotates. .

The hardening 10 thus received is conveyed toward the chute 17 at high speed in the hardening passage 12 by a conveying belt 16 which is in pressure contact with the hardening.

Curing then enters the chute 17 and is then deposited in the deposition cylinder 18. The barrel width setting cam 19 is rotated by a hardening type setting dial (not shown) so that the movable guide plate 15 reciprocates toward the fixed guide plate 14 so that the hardening passage 12 can be made according to the diameter of hardening of various kinds. Sets the width of.

The substrate 26 is installed in the machine frame below the curing passage.

The hardening counting device 20 and the hardening stopper 25 are provided on the board | substrate 26 on the side of the fixed guide plate 14.

In one embodiment, the cure counter 20 has two photosensitive elements or detectors 12, 22 and a park 23, such as an LED (FIG. 2).

The detectors 21 and 22 are arranged to be arranged in the rough triangular space 24 formed by the inner surface of the fixed guide plate 14 and the two peripheral edges of the curing guide when the curing is carried in contact with each other. The detector first blocks light by a specific curing and then the other detector blocks light by a specific curing, while the above-described detector first deviates from the blocking of a specific curing and then the other sensor described above It is arranged to deviate from.

The condition is usually established by arranging the two detectors in a very close position and parallel to the inner surface of the fixed guide plate 14 as shown in FIG.

Note that in this embodiment two detectors 21, 25 are arranged above the stopper 25.

Although configured in the above embodiment as a detector photoelectric transducer, the detector may be made of an elastic spring contact piece that contacts the curing as it passes.

Referring now to FIG. 3, the hardening stopper 25 has a stop shaft 30 protruding upwardly through an opening 34 provided in the trachea 26 and the fixed guide plate 14, the shaft ( The axis of 30 is perpendicular to the substrate 26. The shaft 30 is equipped with the semicircle cut part 31. The horizontal surface 31a of the cut portion 31 is actually on the same plane as the upper surface of the substrate 26, and the vertical surface 31b of the cut portion 31 is in line with the inner surface side of the fixing guide plate 14.

The shaft 30 is connected to a rotary solenoid 32 which is driven according to the count end signal described in detail later.

4 shows a second embodiment of the hardening stopper 25. In this embodiment, the shaft 30 is installed in the cutout 35 formed in the stationary plate 14 and the engine 26 so that the axis of the shaft 30 is parallel to the engine 26. The shaft 30 has a semicircular cut 31 in the same manner as in the first embodiment described above.

5 shows a third embodiment of the stopper.

In this embodiment, the cutting portion 35 for the shaft 30 to receive the shaft 30 ends at the inner side of the fixed guide plate 14, and the cutting portion 31 of the shaft 30 is the upper surface of the substrate 26. Same as that of the second embodiment except that it is disposed opposite to. In this embodiment, the hardening 10 passes through a cut 31 between the trachea 26 and the top of the shaft 30.

FIG. 6 shows a fourth embodiment of the stopper in which the shaft 30 has a groove 36 through which the hardening 10 passes.

7 and 8 show a fourth embodiment of the stopper 25 in which the stop shaft 40 is provided in the substrate 26 and the fixing guide plate 14 in the same manner as in the third degree shaft. It is installed to protrude upward through 42. The shaft 40 has an eccentric disc 41 on top.

In this embodiment, when the eccentric disc 41 is provided in the opening 42 so as not to protrude into the hardening passage (FIG. 7), hardening can pass freely through the hardening passage. When the eccentric disc 41 is rotated 90 degrees or 180 degrees to protrude into the hardening passage (FIG. 8), hardening is stopped.

The operation of the stopper will be described in detail with reference to FIGS. 1 to 3. The hardening supplied to the rotating disc 11 is sequentially supplied to the hardening passage 12 in accordance with the rotation of the rotating disc 11. The guided cure is continuously conveyed in the cure passage by the conveying belt and then passed through the cure counter 20. During the counting operation, the shaft 30 has the vertical surface 31d of the dry end 31 arranged in line with the inner surface so that curing can pass freely through the stopper.

The coin counting device 20 counts the number of coines that pass.

More specifically, the detectors 21 and 22 of the counter 20 generate signals that are processed to sense the passage of the hardening and to be applied to the counter, which will be described in more detail later.

The count end signal is issued to excite the solenoid 32 when the predetermined number of cured water is counted. Therefore, the shaft 30 is rotated 90 degrees or 180 degrees so that the upper portion 31c of the shaft 30 protrudes into the curing passage 12, thereby stopping the continuous curing.

Then, a processing end signal is issued so that the axis returns to the initial position by inverting the axis 30 or further rotating in the advancing direction. The curing machine then prepares for the next cycle.

In FIG. 3 the shaft 30 is properly rotated clockwise to follow the last passing hardening and to stop with only a small impact on subsequent hardening.

An embodiment of an electrical circuit used in the counting device 20 will now be described with reference to FIGS. 9-11.

The detectors 21, 22 receive light from a light source 23, such as an LED, until curing reaches the detectors 21, 22.

Then, while the curing passes over the detector, it is continuously blocked by the curing and again receives light from the light source 23 immediately after the curing passes. The detectors 21 and 22 are electrically connected to the interleaver connections "X" and "Y".

Detector 21 generates pulse A at connection "X" due to light blocking and detector 22 generates pulse B at connection "Y" due to light blocking (FIG. 10).

In the case where the hardening is carried forward, pulse A is first generated and then pulse B is generated at time t ₁ .

In this case, the input connected to the inverter INV ₂ , which is one of the AND gate (AND ₁ ) inputs, and the delay circuit D ¹ is connected by the L level signal of the connection "Y" before the pulse B is generated. The inverted H level signal is supplied through the inverter INV ₂ . Therefore, as shown in FIG. 10B, when the pulse B goes to the H level after the connection portion "X" and the connection portion "Y", the three inputs of the AND gate AND ₁ become the H level, and at the OR gate OR _1, respectively. Supply H level output.

In addition, the pulse B is generated at the connection portion "Y" and the output of the inverter INV ₂ is at the L level, and the charges charged in the capacitor of the delay circuit are discharged.

While the discharge delay is the OR output through a gate (OR ₁₎ is supplied to a flip-flop set input only (S) of (FF ₁₎ as a pulse (FF-S) to set the flip-flop (FF _1).

Accordingly, the H-level outputs FF ₁ -Q are generated at the output Q of the flip-flop FF ₁ .

After that, the hardening continues and the connection "X" becomes L level at time t _2. This signal supplies the H level signal to the 1 input of the NAND gate NAND ₁ through the inverter INV ₁ , and thus delays. Both inputs of the NAND gate NAND ₁ to which the H level signal has already been supplied by the circuit D ₃ become H level. Therefore, an L level signal is outputted to the output thereof, whereby the monostable multivibrator supplies the MM ₁ waveforms of the inverter INV ₃ and the OR gate OR ₃ .

Waveform MM ₁ applies an H level pulse to one of the NAND gate inputs NAND ₃ via inverter INV ₃ .

On the other hand, the waveform MM ₁ is inverted and supplied to the delay circuit D ₅ through the OR gate OR ₃ .

The delayed pulse is supplied to the reset terminal of the flip-flop FF ₁ after being delayed from the time t ₂ , such as the waveforms FF ₁ -R, so that the output Q of the flip-flop FF ₁ is the waveform FF-Q. It becomes L level as follows. As a result, the NAND gate NAND ₃ generates an add pulse at the output and supplies it to the counter C, and the counter is counted by 1 according to this pulse.

When the curing is counted by the counter C and the counted number of curing reaches a predetermined number, as mentioned above, a counting end signal is issued to stop the continuous curing by the axis 30.

During the stationary cure, the first cure covers the detector and thus the detector is shielded from light.

At this time, no further counting occurs because the leading coin is placed at a position corresponding to the time between the times t ₁ and t ₂ .

When the curing process is restarted, such stopped curing passes through the sensor and the counter C counts.

If the hardening that once passed through the detectors 21 and 22 passes reversibly through the reversal movement for some reason, then pulses B are generated followed by pulses A to set the flip-flop FF ₂ . do. In the same manner as described above, the subtracting pulse enters the counter C where the subtraction is performed.

11 shows some cases where cure is reversibly shifted. In the case of I, the hardening moves reversibly before the hardening reaches time t ₁ .

In this case, the counter is not counted.

In the case of II, the hardening is reversibly moved before it reaches time t ₂ .

In that case too, the counter is not counted.

In the case of III, curing is reversibly moved after the time t ₂ has passed. In this case, even if the counter counts down, the counter counts down again because the coin is reversibly moved.

Thus, no more coefficients occur.

In addition, in the case of IV, the curing is reversibly moved after the time t ₂ and then transferred forward before the curing reaches the time t ₁ . In this case, one additional coefficient occurs and no subtraction coefficient occurs. As such, the counter counts down one. In the case of V, the hardening is reversibly moved after time t ₂ and then forward after the time t ₁ .

In this case, one additional coefficient is generated, followed by one subtraction coefficient, which in turn results in another.

As such, the counter counts down one.

From the above, it should be noted that no malfunction occurs because the counter is made with two detectors so that the addition or subtraction coefficients can be made depending on the direction of hardening movement.

Referring now to FIG. 12, there is shown an embodiment of another cure counting device in which one sensor 21a is provided on top of the stopper 25, while the other sensor 21b is equipped on the bottom of the stopper. Indicates. In this case, only the detector 21a is used to cause the counting operation and the other detector 21b may or may not be used to detect the presence of hardening that has passed through the stopper but remains on the substrate 26. .

13 and 14 show diagrams of waveforms implemented for use in circuits, FIG. 12, and the counter 20. FIG. The pulse C generated by the detector 21a is seen at the connection "Z".

In the circuit, the counter can only generate additional coefficients.

It should therefore be noted that the circuit should only be used if the hardening is moved forward.
