The filter plate 3 and the filter frame 4 are arranged alternately so that they can slide on the side plates 2, 2 as tracks.

A first head 7 is provided on the leg body 1a, and a plurality of filter plates 3 and a filter frame 4 are sandwiched between the loose head S and a plurality of filter plates 3 and a filter frame 4 via both end plates 8, 8, and a squeezing operation is performed by tightening with a tightening screw 10. is configured to do so.

Reference numeral 11 is an electric motor with a speed reduction mechanism for opening and closing the loose head 9.

In the filter press constructed in this manner, the rotational motion of the reversible electric motor 12 is transmitted to the speed reducer 13, and the V-belt or chain 14 further transmits and rotates the pulley 15, and the starting reel 16.16 is pivotally connected to the pulley 15. The feeding chain 18.18, which is stretched between the guide reel 17.17, which rotates together with the guide reel 17.17, which is rotatably supported on the opposite ends of the side plates 2, 2 on which the reel 16.16 is supported, can be caused to reciprocate. It looks like this.

The pair of feed chains 18, 18 thus reciprocating along the side plates 2, 2 are arranged to move in parallel.

The feeding device 19 of the present invention is attached to this feeding chain 18.18.
, 19 are attached, and the edges 2a of the two side plates 2, 2,
The feeding devices 19, 19 are placed on the top of the feeding device 2a, and are configured to be able to reciprocate using this as a track.

As shown in FIG. The feed claw 22 for closing the closing plate, the stopper 23 for opening the plate, and the stopper 23 for closing the closing plate are rotatably attached, respectively.
These feed pawls 22, 22 and stoppers 23, 23 are connected to the side plates 20.
It is adapted to elastically protrude from the upper surface of 20.

That is, both ends of the bifurcated spring 24 are connected to feed pawls 22.2, respectively.
2' and the bottom surfaces of the stoppers 23 and 23', the spring 24 is a spring that can slide only in the vertical direction by fitting both ends into grooves 27 and 27 cut in the vertical direction of the side plates 20 and 20. The spring support is inserted through a rod 28 and is supported by the spring support, while the rod 28 is pushed up or down along this tapered surface 30 by horizontal movement of the wedge plate 26 via a roller 29 bearing on the rod 28. Because it does.

The wedge plate 26 is attached to a slide plate 25 that is fitted in a groove 31.31 cut in the horizontal direction of the side plate 20.20 so as to be slidable in the horizontal direction. 22°22 and stopper 23.2
3' elastic protrusion.

A wedge plate 26' having the same shape as the wedge plate 26 described above is attached symmetrically to this slide plate 25, and corresponds to the operation of opening and stopping the filter plate 3 and the filter frame 4, or the operation of closing the filter plate 3 and the filter frame 4. By switching and moving the slide plate 25 to the O position, N position, or S position, the feed claw 22 for opening the plate and frame is moved.
and the stopper 23 is protruded, and the feeding claw 2 for opening the plate and the frame is opened.
2, stopper 23, and feed claw 22' for closing plate closing frame.
and the stopper 23 can be housed, or the feed pawl 22' and the stopper 23' for closing the plate closing frame can be made to protrude.

The bottom surface of the slide plate 25 is provided with an engaging portion that slides along the notches 32 and 32 that serve as faces at the bottom of the side plates 20, 20 (7), and this engages with the inner surface 32a or 32b of the notch 32.
The positions at which the sliding plates 25 abut against each other are made to correspond to the O or S positions of the wedge plates 26 and 26', respectively, to ensure reliable switching movement of the slide plate 25.

Also, chain bolt receivers 33 are provided at both ends of the side plates 20 and 20.
．． 33 are attached, and the feed chains 18 are respectively attached via chain pull bolts 34 and 34 screwed onto these.

Therefore, the tension of the feed chain 18 can be adjusted as appropriate by tightening the chain pull bolt 34.

To explain the operating function of the feeding device constructed as above, in FIG. 1, after the squeezing operation of the filter press is completed, the loose head 9 is opened and moved to the position A by the electric motor 11, and then the The filter plates 3 and filter frames 4 are opened one by one using a feeding device.

That is, the reversible motor 12 for the feeding device is operated to drive the feeding chain 18 and the feeding device 19 is moved to the first head 1.
move it to the side of

The slide plate 25 of this feeding device 19 is manually set at position O, which corresponds to the plate opening operation, as shown at A and 4 in FIG.

Therefore, the feed pawl 22 and the stopper 23 elastically protrude, and the feed pawl 22 is connected to the end plate 8 on the loose head 9 side, which has a banger portion 5' having the same shape as the filter plate 3 shown in FIG.
When it is moved to the position shown in FIG. When the feed claw 22 is rotated and pushed in to position B by sliding while bending the shaped spring 24, and the feed device 19 is further moved, the engagement with the engaging portion 35 is released and the elasticity of the forked spring 24 is reduced. Resilience makes it stand out again.

However, immediately after this, the stopper 23 abuts against the engaging portion 35 of the end plate 8 and stops the movement of the feeding device 19 and the feeding chain 18.

That is, since the stopper 23 is prevented from rotating in the direction of the arrow 37 by the distance 36 screwed at both ends to the side plate 20.20, it receives the feeding force acting on the feeding device 19 and stops the movement of the feeding device 19. It is.

In addition, the feed claw 22 also has a distance 36 similar to the stopper 23.
Rotation is stopped in the direction of arrow 38 by.

Since the reversible electric motor 12 is operating while the movement of the feeding device 19 and the feeding chain 18 is thus prevented, this operation must be stopped manually or automatically.

There are various ways to automatically stop the operation of the reversible electric motor 12, but the one devised by the present inventor is one in which a starting wheel is connected to the rotating shaft of the reversible electric motor and a bearing plate is supported on the rotating shaft. Guide wheels are installed on both sides of the starting wheel, and a chain is passed through these three gear wheels in a W-shape, and the chain is stretched around a pulley to form a loop. When the mechanism prevents the reciprocating feed chain from moving, torque is applied to the bearing plate, and a limit switch activated by rotation of the bearing plate stops and reverses the reversible motor. The use of a transmission device can make the invention even more advantageous.

That is, when the movement of the feeding chain 18 is prevented as described above by the stopper 23 of the feeding device 19 of the present invention, since the reversible electric motor 12 is operating, torque is applied to the bearing plate of the transmission device, causing it to rotate. The limit switch is actuated to automatically stop the reversible motor 12.

Subsequently, the reversible motor 12 is reversed and the feed pawl 2 of the feed device 13 is rotated.
2 is engaged with the engaging portion 35 of the end plate 8 and separated and transferred to the loose head 9 side. As mentioned above, the feed pawl 22 is automatically projected by the elastic restoring force of the forked spring 24. When the end plate 8 is engaged with the engaging portion 35 and the transmission device is used, the reversible motor 12 is automatically reversed by the operation of the limit switch, so that the end plate 8 is automatically transferred.

- When the end plate 8 is transferred to the loose head 9 at position A and collides with it, the movement of the feeding device 19 and the feeding chains 1, 8 is blocked, so that the rotation of the reversible motor 12 can be controlled manually or by the transmission. When the device is used, a torque is applied to the bearing plate in the opposite direction to that described above, and a limit switch activated by this rotation automatically stops the bearing plate.

At this time, the cake is peeled and discharged, and the remaining filtrate and filtrate are washed.

After the above operation is completed, the reversible electric motor 12 is operated in reverse again to move the feeding device 19 toward the first head 7 side.

At this time, the stopper 23 of the feeding device 19 is moved to the loose head 9.
Inverted trapezoidal claw pushing devices 39a, 3 attached to both sides of the
Since the bifurcated spring 24 is bent by 9a and housed in the feeding device 19 as in the state shown in C,
Only the feeding device 19 moves, leaving the transferred end plate 8 at the position.

Note that the reversing operation of the reversible motor 12 is not performed automatically but manually.

The stopper 23 of the feeding device 19 transferred to the first head 7 side in this way abuts against the engaging portion 40 protruding from the banger portion 6 of the filter frame 4, and this movement is blocked and the feeding claw 22 is engaged with the engaging portion 40, and the filter frame 4 is opened and transferred by the reversible operation of the reversible motor 12.

The positions of the engaging portion 40 protruding from the bunger portion 6 of the filter frame 4 and the engaging portion 35 of the end plate 8 or filter plate 3 from the side plate 2 are shown in FIGS. 2 and 3. When assembled as shown in Figure 1, they are arranged in parallel and alternately in the sliding direction, so the spacing between the engaging parts in the sliding direction is the same as the engaging parts of the filter frame, filtrate, and end plate. This is twice as many as when they are arranged in a straight line, and the feeding claws can be held easily and reliably even with thin filter plates and filter frames.

Further, as shown at the opening in FIG. 4, the feed claw 22 pinches the collar 41 inserted through the pin 21 and separates it into two parts, each of which operates independently.

The upper feeding claw is the filter plate 3 or the end plate 8.
The lower side is for engaging the filter frame 4.

When the feeding device 19 transports the filter frame 4 until it abuts against the end plate 8, the reversible motor 12 is stopped manually or by actuating a limit switch of the transmission device.

Next, the reversible electric motor 12 is manually operated in reverse again to transfer the feeding device 19 to the first head 7 side. Since the transfer device 19 is configured to be pushed into the device 19, only the feeding device 19 can be returned to the first head 7 side, leaving the transferred filter frame 4 behind.

The above transfer operation is repeated to transfer the filter plates 3 and filter frames 4 one by one one by one.

On the other hand, when the filter plate 3 and the filter frame 4 are transferred to the closing plate closing frame using the feeding device 19 of the present invention, the slide plate 25 is switched to the S position and the feeding pawl 22 and stopper 23 for closing the plate closing frame are protruded. The filter plate 3 and the filter frame 4 can be transferred smoothly and efficiently by performing the operation opposite to the above-described plate-opening and frame-opening operation.

Note that the loose head 9 is also provided on both sides of the first head 7.
A claw pushing device 38 having the same function as the claw pushing device 39a of
b is installed.

Further, stoppers 42.42 for preventing the feeding device 19.19 from falling off are attached to both ends of the edges 2a, 2a of the side plate 2.2 which serve as the orbit of the feeding device 19.19.

In FIG. 1, reference numeral 43 denotes a bolt for adjusting the tension of the feeding chain 18 by adjusting the fixing position of the guide reel 17, which is slidably installed in the longitudinal direction at the end of the side plate 20.20. 44 is the lock nut.

As described above, the filter press feeding device of the present invention can semi-automatically transport the filter plate and filter frame of a thin duplex filter press, thereby eliminating the waste of human power and time required for removing and assembling the filter plate and filter frame. The present invention provides smooth and efficient operation of the filter press by significantly reducing the amount of noise, and has great practicality as it has a relatively simple structure and can be mass-produced at low cost.

In the above explanation, the case where the device of the present invention is used in a double-type filter press has been explained, but the present invention is not limited to this, and can easily be applied to a single-type filter press as well as other types of filter presses by appropriately changing the design. It can be used for.
