Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the automation of a sake brewing press, particularly the opening device.

[Conventional technology]

Conventionally, the opening device of a sake brewing press has a plate opening device equipped with a plate opening claw attached to the bottom of two rows of endless chains stretched by two pairs of sprockets, and the plate opening device is moved in the left and right direction by driving the sprocket. As if moving, a worker held the overplate or compression plate between the plate opening claws and drove the motor while pressing the manual switch, and visually confirmed the predetermined opening position.

[Problem that the invention attempts to solve]

As mentioned above, in the past, a worker pressed the motor switch and drove the sprocket to move the plate opener to the target position, but it was troublesome for the worker to press the motor switch while checking the position each time. Moreover, it was difficult to confirm the exact opening position.

[Means for solving problems]

Torque limiters are installed in the front and rear rows of the drive sprocket of the endless chain for moving the plate opener.
A driven sprocket is engaged with each of the two rows of endless chains from above, and one of the driven sprockets connects a position checking cam through a clutch, and the other connects a position checking and stopping cam through a clutch. The cams are shaft-mounted in a phase-shifted manner, and a limit switch is provided opposite to each of these cams, and both of the clutches are closed at a position where the opening claw engages with the overplate or compression plate located at the head of the pressurizing position. In this way, when the plate-opening pawl accommodates an over-plate or a squeeze plate and moves in the opposite direction, the stop limit switch is activated to stop the movement of the plate-opening pawl and activate the sludge peeling device. If one of the two position confirmation limit switches is not transmitting a signal, the operation of the lees peeling device is prevented.

[Effect]

When the clutch is open, the position confirmation cam and limit switch are engaged, but when the opening claw is engaged with the overplate or compression plate, the clutch is closed, and the position confirmation cam rotates once due to the operation of the stop limit switch. It will be stopped. Therefore, the reverse travel distance of the opening pawl is always constant, and when the two reverse travel distances do not match, one of the position confirmation limit switches does not make a signal, making it easy to detect the inclination.

Next, the operation of the above embodiment will be explained.

When the movable pressure plate 1d retreats to the right after the movable pressure plate 1d has compressed the overboard 2 and compression plate 3 groups, a manual switch (not shown) moves the traveling frame 5 equipped with the peeling devices 19, 19'. Peeling device 19,
19' is configured to automatically stop at a lees peeling position a certain distance away from the rightmost overboard 2 or pressing board 3 at the pressing position by a detector (not shown), and such movement of the traveling frame 5 - The stop is performed by sequentially shifting the position to the left, and for this reason, the single sheet delivery plate 2 or the pressing plate 3 is alternately brought to the release position, that is, the peeling position, by the action of the plate opening device 25, which will be explained below. , lees peeling is performed by peeling devices 19, 19'.

The operation of the plate opening device 25 will be described below.

First, prior to operation, the cams 40, 40' are brought into engagement positions with the limit switches 42, 42', and the cams 40, 40'
1 is a position slightly deviated from the limit switch 44 (a position slightly advanced relative to clockwise rotation of the cam, and a delay angle from when a stop signal is issued to when the cam actually stops)
(See Figure 7). This is only the first time, and from then on, as long as the cam stops operating normally, this phase shift state will occur automatically.

Once the cam position setting is completed, the above-mentioned traveling frame 5
Following this, the peeling devices 19, 19' stop at the peeling position due to the running of the plate opening devices 32, 32'.
Once moved to the peeling position. This completes the preparation for automatic operation (Figure 8).

Turn on the automatic switch (not shown). At the same time as the motor 29 rotates forward, a first timer (not shown) operates. When the plate openers 32, 32' move to the left and the plate opening claws 32a, 32'a collide with the top overplate 2 or pressing plate 3, the spring 3 is released through the inclined surface of the back of the claw.
2c and 32'c, the pawl is pushed up (the state shown by the two-dot chain line in Fig. 4), and, for example, the leading overplate 2 is placed in the groove between the plate openers 32a, 32b, 32'a, 32'b. Torque limiters 28a, 28' in the stored state
The plate openers 32, 32' become stagnant due to the action of a, and eventually the motor 29 is turned on due to the time up of the first timer.
stops (states shown in Fig. 9, solid line in Fig. 4, and Fig. 12).

Due to the time up of the first timer, the clutch is 38,
38' turns ON and the motor 29 reverses.
The plate openers 32, 32' move in the opposite direction while housing the overplate 2 or the pressing plate 3. clutch 38, 38'
Since it is ON, sprocket 39,3
With the rotation of 9', the cams 40, 40', 1 also rotate,
First, a stop signal is sent to the motor 29 by the engagement between the cam 41 and the limit switch 44 (see Fig. 13), and the position where the cams 40, 40' are slightly advanced due to inertia and the limit switches 42, 42' engage (see Fig. 14) (see), the plate openers 32, 32' completely stop. This position is 1 of sprockets 38 and 38'.
Rotation position, i.e., predetermined peeling position (see Figure 10)
It is becoming.

Simultaneous transmission of the limit switches 42, 42' activates a second timer (not shown), and at the same time, the scum peeling devices 19, 19' start operating, and the plate opening device 32,
A dregs peeling operation is performed on the overboard 2 or pressing board 3 housed in 32'. When the second timer is set to a time appropriate for the stripping work, the clutches 38 and 38' are turned off and the motor 29 is turned off again.
is operated in reverse, thereby opening the plates 32, 3.
2' moves the overboard 2 or pressing board 3 that has completed peeling to the completion tank on the right, and at the same time
The timer is activated.

In the reservoir, the torque limiter 28 is activated when the overplate 2 or compression plate 3 that has moved to the rearmost overplate 2 or compression plate 3 in the reservoir is in a collision state.
The plate opening devices 32, 32' become stagnant due to the operation of the plates 28'a and 28'a (see Fig. 11), and the bottoms of the plate opening claws 32b, 32'b that have moved at this time and the overplate 2 or pressing plate 3 in the reservoir are By engaging with the claws 32b, 32'
b is pushed up (see the two-dot chain line in FIG. 4, however, the first one is due to engagement with the moving pressure plate 1d). Third
When the timer times up, the motor 29 starts rotating in the normal direction and a fourth timer (not shown) is activated.

As a result, the plate openers 32, 32' move to the left again, leaving the overplate 2 or compression plate 3 that has been peeled off in the storage area, and store the next overplate 2 or compression plate 3 at the compression completion position. Head over. Hereinafter, among the above-mentioned steps, except for the first timer, the circulation operation is performed, and the overplate 2
The process of storing the overboard 2, etc., peeling work, and moving the peeled overboard 2, etc. to a storage area is repeated.
Note that the claws 32b and 32'b can be returned to their original positions using the plate opener 3.
This is automatically done by the left row of 2, 32'.

In the above-mentioned process, if either of the plate opening claws 32 or 32' is delayed for some reason while the plate opening devices 32, 32' are moving toward the peeling position after storing the overplate 2 or the pressing plate 3, the peeling will not be possible. When stopped at this position, the overboard 2 or the pressing board 3 will be slanted, which will impede the next peeling operation. However, in this case, the delayed or advanced cam 40 or 40' is not engaged with the limit switch 42 or 42', and therefore both limit switches 42, 42' are not operating simultaneously. Therefore, an alarm is issued and the operation of the peeling devices 19, 19' is stopped.
In this case, the normal automatic operating state can be restored by having the operator manually adjust the position of the overplate 2 or compression plate 3 to the point where both limit switches 42, 42' are at the same time transmitting position.

In addition, in the above explanation, the overboard 2 and the compression board 3
However, the invention is not limited to this, and if one of the two is used to remove the lees more easily than the other, the lees can be attached to the other side. This means that only the peeling work is required.

In this case, the clutches 38, 38' are turned ON and the accommodated overplate 2 or compression plate 3 is moved to the peeling position, and the clutches 38, 38' are not turned ON and the accommodated overplate 2 or compression plate 3 is moved to the peeling position. The control device may be set so as to alternately move the plate 3 straight to the right-hand end storage area, and stop at the peeling position only when the plate is used for peeling off dregs.

[Effect of idea]

As detailed above, in the device of the present invention, a torque limiter is provided on each of the driving sprockets arranged in the front and rear rows, and an endless chain is stretched, and a disc opening device with a disc opening pawl is attached to each of the endless chains in the front and rear rows. At the same time, driven sprockets are engaged separately, and each of the sprockets is provided with a position confirmation cam through a clutch, and a stopping cam is provided with only one of them out of phase, and all of these cams are provided with limit switches facing each other. and when the clutch moves in the reverse direction with the opening pawl accommodating the overboard or pressing plate at the head of the pressurizing position, the clutch stops the movement of the opening pawl and activates the dregs peeling device by transmitting a stop limit switch; At this time, if one of the two limit switches for position confirmation does not emit a signal, the operation of the lees peeling device is prevented, so that the over plate or pressing plate is at a fixed position within one rotation distance of the driven sprocket from the pressurizing position. It will be separated,
The pressurizing position of the overboard or pressing board can be automatically matched with the waiting lees peeling device,
Therefore, it has become possible to continuously automate the opening and peeling processes.

Moreover, if the front and rear opening claws do not move in sync for some reason, the two position confirmation limit switches do not simultaneously issue an alarm and automatically activate the lees peeling device. This eliminates the need for workers to check the stopping position each time as in the past, and allows for highly reliable and reliable automation.
