Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door plate feeding device for a filter press, and particularly to a door plate feeding device that can transfer a door plate in either the left or right direction.

As a prior art of such a door plate feeding device, there is a door plate feeding device described in Japanese Patent Publication No. 16590/1983 by the applicant of the present application.

This technology involves interposing an idler between a forward-feeding pawl and a reverse-feeding pawl that are rotatably arranged opposite each other, and converting the biasing direction of this rotor between the forward-feeding pawl side and the reverse-feeding pawl side. This makes reversible transfer possible.

However, in this prior art, the biasing direction of the swinger must be changed manually each time, which requires manpower and has the drawback that a smooth door plate feeding operation cannot be performed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a door plate feeding device that can eliminate the drawbacks of the prior art as described above and can automate and smooth the door plate feeding operation.

Specifically, FIGS. 1 and 2 show side views of the entire apparatus according to the present invention, 1 and 2 are machine frames before and after the filter press, and 1 is a fixing plate for the door panels 3, 3... becomes.

4 is a side plate fixed between the machine frames 1 and 2, and the door plate 3
, 3... are arranged on both sides.

Each door plate 3, 3, .

6 is a movable plate.

This movable plate 6 is fixed to a piston rod (not shown),
The door panels 3, 3, . . . are squeezed by moving forward and backward together.

7 is a P cloth weight arm, and 8 is a furnace cloth.

Reference numeral 9 denotes a transporting body for the door plate 3, which is attached to an endless belt 10 driven by a drive source (not shown), and moves together with the endless belt 10.

Reference numeral 11 denotes a guide for the transport body 9, which is provided along the side of the side plate 4.

The handle 5 of the door plate 3 projects above the guide 11.

12 is a furnace cloth cleaning vehicle.

In the state shown in Figure 1, after the filtration of the stock solution is completed, the door plates 3 and 3
The door plates 3, 3, . . . in the stacked state are sequentially opened and transferred one by one to the movable plate 6 in the retreated position in order to remove the cake remaining in between.

If we assume that the movement of the door plate 3 toward the movable plate 6 is normal feed, and the movement toward the fixed plate 1 is reverse feed, the state shown in Fig. 1 corresponds to the normal feed state by the transfer body 9 for discharging the residual cake. show.

On the other hand, FIG. 2 shows the state of furnace cloth cleaning performed after discharging the residual cake, and cleaning liquid is jetted from the jet pipe 13 of the cleaning wheel 12 to the furnace cloth 8 which is in an open state to clean the furnace cloth 8.

Furnace cloth cleaning is performed on the door plate 3 located on the movable plate 6 side after the cake is discharged.
, 3, .

As is clear from the above, the door plate must be fed forward and backward by the transporter 9 before the cleaning of the furnace cloth is completed after the filtration work is completed.

Therefore, it is important for the forward and reverse feeding by the transport body 9 to be carried out quickly in order to facilitate the work.

Further, the quick changeover between forward and reverse feeding of the furnace plate 9 by the transfer body 9 is equally important in maintenance and inspection of the filter device.

To further explain the transfer body 9 with reference to FIGS. 3 to 5, FIG.
FIG. 4 is a side view with a part of the side wall 14 of the transfer body 9 cut away, and FIG.
This is the A section.

Reference numeral 15 denotes a normal feed pawl, and the normal feed pawl 15 is rotatably mounted between the side walls 14, 14 of the transfer body 9 via a shaft 15a.

The normal feed pawl 15 is urged clockwise in the drawing by a spring 16.

Reference numeral 17 denotes a reverse feed pawl, and the reverse feed pawl 17 is also rotatably mounted between the side walls 14, 14 of the transfer body 9 via a shaft 17a.

The reverse feed claw 11 is moved by the spring 18 to the normal feed claw 15.
On the contrary, it is biased counterclockwise.

That is, the normal feed pawl 15 and the reverse feed pawl 17 constitute a pair of feed pawls that are biased inwardly by springs 16 and 1B, and are arranged at a constant gap from each other.

Note that one end of the biasing springs 16 and 18 is connected to the shafts 15a and 1, respectively.
5a, and the other end is locked to the side wall 14 of the transfer body 9.

Reference numeral 20 denotes a swinger having arm portions 21 and leg portions 22.

The shaft 21a to which the arm portion 21 is fixed and the shaft 22a to which the leg portion 22 is fixed are formed into a concentric double shaft.
The shaft 22a is supported by the side walls 14, 14 of the transfer body 9, so that both the arm portion 21 and the leg portion 22 are rotatable.

Furthermore, one end 23a of the coil spring 23 attached so as to be wound around the shaft 21a of the arm portion 21 is locked to the arm portion 21,
By locking the other end 23b to the shaft 22a of the leg portion 22 (see FIGS. 4 and 5), the arm portion 21 and the leg portion 22 are connected using the urging force of the coil spring 23 (shown in the third drawing). are biased so that they form an angle of 180 degrees with each other.

Note that the relationship between the arm portion 21 and the leg portion 22 is such that each of them is rotatable and spring-biased so that they form an angle of 180 degrees with each other.
In addition to configuring the shaft 2a as a concentric double shaft, for example, the leg 22 is attached to the end surface of the shaft 21a of the arm 21 which is rotatably held by a hinge connection using a pin or a ball.
It is also possible to spring bias the arm portion 21 and the arm portion 21 to form an angle of 180 degrees.

21b is a roller of the arm portion 21, and the arm portion 21 is interposed between the normal feed pawl 15 and the reverse feed pawl 17 by the roller 21b, and is configured to push or be pushed between the pawls 15 and 17. Become.

22b is a roller of the leg portion 22, which rolls on the support surface 24 as the transfer body 9 moves.

The length of the leg portion 22 including the roller 22b is the length of the leg portion 22
The distance from the shaft 22a to the support surface 24 is longer than the distance from the shaft 22a to the support surface 24, so that the leg portion 22 is supported in an inclined state tilted from the perpendicular direction with respect to the support surface 24.

In this embodiment, the support surface 24 uses the bottom inner wall of the guide 9, but is not limited thereto.

Note that 25 is a pit formed in the support surface 24, and when the roller 22b of the leg portion 22 falls into the pit hole 25, the inclined support of the leg portion 22 by the support surface 24 is released.

In short, the pit 25 only needs to allow the vertical posture of the leg 22, and therefore, such a recess may be used instead of the pit 25.

Further, the pit holes 25 are provided at two locations on the bearing surface 24, and these locations will be further described later.

A stopper rod 26 is rotatably supported behind the normal feed pawl 15.

Reference numeral 26a denotes a shaft to which a stopper rod is fixed, and by bearing the shaft 26a between the side walls 14, 14 of the transfer body 9, the stopper rod 26 is rotatably supported as described above.

The stopper rod 26 has a spring 21 wound around its shaft 26a.
(See FIG. 3) is biased in the counterclockwise direction in FIG. 4.

A first stopper 28 supports the stopper rod 26 in a horizontal position by coming into contact with the locking piece 26b of the stopper rod 26, and prevents further rotation in the counterclockwise direction.

Reference numeral 29 denotes a second stopper, which comes into contact with the stopper rod 26, thereby tilting the stopper rod 26 into a downwardly inclined position (as shown by the imaginary line in FIG. 4).

) and prevent further clockwise rotation.

In its horizontal position, the stopper rod 26 abuts the normal feed pawl 15 in the upright position from behind, thereby preventing the normal feed pawl 15 from falling further backward.

In addition, the stopper rod 26 further moves backward from the upright position of the normal feed pawl 15 to the rear transport body 9 in its downwardly inclined position.
Allow to fall inward.

Reference numeral 26c denotes a handle of the stopper rod 26, which is fixed to a protrusion from the side wall 14 of the shaft 26a, which is supported by the side walls 14, 14 of the transfer body 9.

The handle 26c is attached to the stopper rod 26 at an obtuse angle, and when the stopper rod 26 is in a horizontal position, the handle 26c assumes an upwardly inclined position (as shown by the solid line in FIG. 4).

], when the stopper rod 26 is in the downwardly inclined position, it assumes a vertically standing position (as shown by the imaginary line in FIG. 4).

). 26a is a roller provided at the tip of the handle 26c.

Reference numeral 30 denotes a holder for holding the handle 26c of the stopper rod 26 in an upright position, and is attached to the side wall 14 of the transfer body 9. A portion 30a of the holder 30 serves as a leaf spring to hold the handle 26c of the stopper rod 26 in an upright position.
Hold c with appropriate force.

31 is a third stopper (see FIG. 4), which is installed between both side walls 14 and 14 of the movable body 9 like the second stopper 29;
A reverse feed claw 17 which is located behind the reverse feed claw 11 and is in an upright position is supported from behind.

32 is a guide roller for preventing the transport body 9 from shaking;
Two are provided at the front and rear of the transport body 9.

Reference numeral 33 denotes wheels of the transporting body 9 (see FIGS. 3 and 5, shown in the lower part of FIG. 4), and one wheel is provided coaxially with the guide roller 32 at the lower center of the front and rear positions of the transporting body 9.

34 is a movement path of the transport body 9, in this example, the transport body 9
Another plate is superimposed on the center of the bottom wall of the guide 11, and the wheels 33 roll on the moving path 34.

Referring to FIGS. 1 and 2, 35 is a locking member, and 36 is a lock release member.

The locking member 35 is located further away from the fixing plate 1 of the filter press (see Figs. 1 and 2, the fixing plate 1
(more to the left), the moving body 9 contacts the handle 26c of the stopper rod 26, pushes it against the spring 27, and holds it in the holder 30.

In this holding state, the stopper rod 26 assumes a downwardly inclined position (phantom line in FIG. 4).

On the other hand, the lock release member 36 is in a position further removed from the retracted position of the movable plate 6 of the filter press (see FIGS. 1 and 2), and the handle 26c is perpendicular to the moving transfer body 9. When the handle 26c is in the state (held by the holder 30), it comes into contact with the handle 26c, and the handle 26c is pushed to release the grip 26c from being held by the holder 30.

The abutting positions of the lock member 35 and the lock release member 36 are the two moving ends of the transfer body 9.

One of the pitfalls 25 that allows the vertical posture of the legs 22 of the swinger 20 is that the transfer body 9
is provided before coming into contact with the locking member 35 (
In this example, it is provided at the position of the fixed plate 1.

9.10.11), and the other one is provided between the movable plate 6 in the retreated position and the lock release member 36 (see Figure 9.10.11).
In this example, the transfer body 9 is provided at a position where it comes into contact with the lock release member 36.

(See Figure 6).

Next, the operation of this device will be explained with reference to FIGS. 6 to 15.

Figure 6 shows the movable plate 6 after filtration by the filter press has been completed.
shows a state in which it has retreated to the retracted position, and the transport body 9 is in the standby position.

In this standby position, the transfer body 9 has the legs 22 of the slider 20 fitted into the pit holes 25, and the slider 20 is in a vertical position and the forward feed pawl 15 and reverse feed pawl 17 are in a free state. are in contact.

Further, the handle 26c of the stopper rod 26 of the transfer body 9 comes into contact with the lock release member 36 and is released from being held by the holder 30.

Now, to explain the normal feeding of the door plate 3 from this state, that is, the case where the door plate 3 is sent from the fixed plate 1 side to the movable plate 6 side, first, the fixed plate 1 shown by the X arrow indicates the transfer body 9 in the state shown in FIG. Move it to the side.

Then, as shown in FIG. 7, the normal feed pawl 15 first hits the handle 5 of the door plate 3 located at the farthest end (the right end in the drawing), and is pushed by the handle 5, so that the normal feed pawl 15 sinks toward the lower surface of the handle 5.

After passing through the handle 5, the normal feed claw 15 attempts to pass through the next P plate 3 handle 5 as well, but this time it is pushed up by the normal feed claw 15 and the arm portion 21 of the floater 20. The reverse feed claw 1T contacts the handle 5 and is prevented from moving.

Since the reverse feed pawl 17 in the upright state is prevented from rotating clockwise by the third stopper 31, the force with which the reverse feed pawl 17 presses on the handle 5 increases, and as a result, the limit switch operates and the direction of movement is changed.

On the other hand, when the normal feed pawl 15 passes through the handle 5, it is raised up by the idler 20.

This is because the leg portion 22 of the idler 20 is inclined downward to the right in the drawing by the support surface 24, and the arm portion 21 is biased by the spring 23 toward the upper left in the drawing, that is, toward the normal feed claw 15 side. It is.

Therefore, as described above, the moving direction of the transport body 9 is changed,
With the start of movement in that direction (the opposite direction to the direction of the X arrow, indicated by the Y arrow in the drawing), the normal feed pawl 15 moves towards the handle 5.
When the reverse feed claw 17 comes into contact with the handle 5 and moves away from the handle 5, it sinks into the transport body 9 by the biasing force of the spring 18 (see FIG. 1).

In this state, the normal feed pawl 15 is supported from behind by the stopper rod 26 in a horizontal position, and therefore, the movement of the transporting body 9 in the direction of the X arrow moves the door plate 3 toward the movable plate 6 as shown in FIG. can do.

Once the door plate 3 is moved toward the movable plate 6, the transfer body 9 cannot be moved any further, so the handle 5 is moved by the normal feed claw 15.
The pressing force increases, and as a result, the limit switch operates, and the transporting body 9 moves in the direction of the X arrow again.

By repeating the above operation, all the door panels are 3゜3...
can be forwarded sequentially.

This normal feeding is used to discharge the cake as described above.

When the normal feeding of all the door plates 3, 3, . By the way, stop.

Reverse feeding of the door plate 3 starts from the state shown in FIG.

Therefore, if you want to start reverse feeding immediately after the forward feeding is completed, actuate the limit switch when the conveying body 9 is in the state shown in FIG. 9, and immediately move the conveying body 9 reversely in the direction of the It's okay.

A case will be described in which the door panels 3, 3, . . . are sent in the opposite direction, that is, the door panels 3, 3, .

First, the transport body 9 is moved in the direction of the X arrow from the state shown in FIG.

Then, as shown in FIG. 13, the reverse feed claw 15 is first pushed down into the handle 5 of the door plate 3 located at the farthest end (left end), and the handle 5 is pushed down.
Go through.

However, before the reverse feed pawl 15 passes through the handle 5 of the next door plate 3, the movement of the transfer body 9 is blocked by the contact of the forward feed pawl 15 supported by the stopper rod 26 with the handle 5.

As a result of the increase in the pressing force between the handle 5 and the normal feed pawl 15, the moving direction of the transfer body 9 is reversed to the direction of the X arrow.

On the other hand, when the reverse feed claw 17 passes through the handle 5, it is raised up by the idler 20.

This is because the transport body 9 has been moved in the direction of the X arrow from the position of the pit 25 in FIG.
is inclined to the lower left in the drawing, so the arm portion 21
This is because the spring 23 is biasing the reverse feed claw 17 side.

Therefore, as described above, the moving direction of the transfer body 9 is reversed to the direction of the X arrow, and as the movement in that direction begins, the reverse feed claw 17 comes into contact with the handle 5, while the forward feed claw 15 contacts the handle 5. By moving away from it, it falls down into the transport body 19 by the biasing force of the spring 16.

In this state, the reverse feed claw 1T in the upright state is the stopper 3.
1 from behind, and therefore, by moving the moving body 9 in the direction of the X arrow, the door plate 3 can be moved toward the fixed plate 1 as shown in FIG.

Once the furnace plate 3 is moved toward the fixed plate 1, the transfer body 9 cannot be moved any further in the same direction, so the pressure force applied to the handle 5 by the reverse feed claw 11 increases, and as a result, the limit switch is activated. Then, the transport body 9 moves again in the direction of the X arrow.

By repeating the above operations, all the door plates 3, 3, . . . can be sequentially reversed (see FIG. 15).

Utilizing this reverse feeding, the furnace cloth 8 can be cleaned by the cleaning wheel 12 as described above.

After reversing the last door plate 3, the transfer body 9 moves to the movable plate 6 side (
However, since the door plate 3 no longer exists, it continues beyond the position of the movable plate 6 to the lock release member 36, where it is expected to wait.

In this standby position, as shown in FIG. 1, the leg portion 22 of the idler 20 of the transfer body 9 is fitted into the pit hole 25, and the idler 20 takes a vertical position and the normal feed pawl 15 in the free state and the reverse It is in contact with the feed claw 17.

Next, a case will be described in which, after normal feeding by the transporting body 9, reverse feeding is not performed.

Referring to FIG. 9 to FIG. 12, first, the door panels 3, 3...
After completing the normal feeding, the transfer body 9 in the state shown in FIG. 9 is roughly moved in the direction of the X arrow to the locking member 35.

As a result, the handle 26c of the stopper rod 26 is pushed by the locking member 35 and is held by the holder 30 in a vertical position.

As a result, the stopper rod 26 assumes a downwardly inclined position as shown in FIG.

Next, the transport body 9 is moved in the direction of the X arrow.

The transport body 9 passes through the state shown in FIG.
3... moves toward the movable plate 6 side, but passes through without engaging the door plates 3, 3.

That is, as shown in FIG. 12, the reverse feed claw 1T is connected to the handle 5.
The normal feed pawl 15 is also no longer supported by the stopper rod 26, so the handle 5 causes it to fall down counterclockwise.

Therefore, the transport body 9 passes through the state shown in FIG. 12 and moves to the standby position of the transport body 9 shown in FIG.

At this standby position, the stopper rod 26, which is released from the hold by the holder 30 by the lock release member 36, assumes a horizontal position again, and the idler 20 fits into the pit hole 25 and assumes a vertical position.

In short, the above action is to automatically change the biasing direction of the idler 20 using the two pit holes 25° 25, thereby freely allowing normal feeding and reverse feeding.
By automatically changing the posture of the stopper rod 26 at the moving end of the transport body 9, after the normal feeding operation is completed, the stopper rod 26 is made to wait at the original standby position under the selection without performing reverse feeding or without performing reverse feeding. .

The present invention has the above configuration, and the furnace plate 3,
The forward and reverse feeding of 3... is possible only by changing the moving direction of the transfer body 9 using a limit switch, remote control, etc., and there is no need to manually change the energization of the idler as in the past.

Moreover, since the posture of the stopper rod 26 can be changed,
It is possible to freely decide whether or not to reverse the door panels 3, 3.

From this point of view, according to the present invention, it is possible to automate the door plate feeding operation, and the series of operations such as cake discharge and P cloth washing becomes extremely smooth, and it is possible to reduce the time required.

In addition, operations such as maintenance and inspection of the device become smoother.
