Description

[Detailed description of the invention] This invention relates to a plate feeding device for a filter press.

In the conventional method, a plate transfer body having removable claws is attached to the end of the plate to a conveyance belt that can reciprocate in the direction of stacking the plates, and the plates are sequentially transferred by reciprocating the plate transfer body. In the case of the plate feeding device of a filter press, depending on the conditions such as the thickness of the edge of the plate to which the pawl of the plate transfer body engages and disengages, the pawl may need to be replaced, or the pawl and its accompanying mechanism may need to be replaced. In the event of a failure, the entire plate transport body must be removed from the transport belt, which is a troublesome process and has extremely poor workability.

The object of this invention is to eliminate the above-mentioned drawbacks of the conventional example and to provide a plate feeding device for a filter press that facilitates operations such as replacing and repairing the pawls.

In FIG. 3, reference numeral 34 denotes a stopper pin that is horizontally suspended between both side walls of the main body frame portion 9, and is designed to prevent the stopper claw 13 from rotating beyond the standing position against the biasing force of the torsion spring 26. ing. 35,3
Reference numerals 6 denote reinforcing pins that are horizontally suspended between both side walls of the transport body frame member 11, respectively. Each stopper pin 30, 34 for the feed claw stopper 14 and the stop claw 13
is also used as a reinforcing pin.

The second plate transfer body 8' is the same as the first plate transfer body 8 except that the stop claw 13 and the slider 15 of the first plate transfer body 8 are omitted.

Near the end of the chain guide 20 on the fixed plate 4 side and near the end of the movable plate 5, there is a Separate actuators 37a and 37b shown in FIGS. 6 to 11 are provided so as to maintain the spacing, and the second plate transfer body 8' connects the terminal end of the fixed plate 4 side and the movable plate 5.
When the side terminal end is approached, the feed pawl set lever 31 of this plate transfer body 8' acts on these actuators 37a, 37b, and the feed pawl stopper 1
4 to a predetermined posture.

The above is an explanation of the configuration of one side bar 1 of the filter press, but by configuring the same thing on the other side bar 1 and using the motor 6 as a common drive source, both sides can be The mechanisms are driven synchronously so that the plates 2 can be pulled stably on both sides.

Note that above the filter press, a cloth vibrating device 38 and a cloth cleaning device 39 are arranged at a predetermined interval from the fixed plate 4 side to the movable plate 5 side.
Vibration processing and cleaning processing of the cloths 3, 3 can be automatically performed during the transfer of the plates 2. Each plate 2... is connected by pivoting the tips of a pair of cloth hanging arms 2b, 2b, which are pivotally attached to each side, between adjacent plates 2, 2. The cloth lifting arm 2
When the transfer of each plate 2 has progressed to the position where the tip pivot joints of b and 2b act, the motor 6 is stopped each time by the operation of these limit switches 40 and 41, and the cloth vibrating device 38 and the cloth cleaning device 39 are stopped. I'm trying to start it.

Next, the operation of this board feeding device will be explained.

(1) While the filter press is performing the compression process, the first and second plate transfer bodies 8, 8' are in a standby state at the end portion on the side of the movable plate 5. At this time, the feed pawl set levers 31, 31 of each plate transfer body 8, 8' are connected to the actuator 32, respectively.
b, 37b, and is restricted to the prone position shown in FIGS. 6 to 8. Therefore, in the first plate transfer body 8, the feed pawl stopper 14 assumes a horizontal position and holds the feed pawl 12 in an upright position. On the other hand, the stop claw 13 has a torsion spring 26
It is tilted down toward the fixed plate 4 side by the biasing force.
On the other hand, the second plate transfer body 8' also has a similar action, so that its feed claw stopper 14 takes a horizontal position and the feed claw 12 is held in an upright position.

(2) When the compression process of the filter press is completed and the movable plate 5 is retracted leaving the plates 2 on the fixed plate 4 side, when a drive command is given to the motor 6, the endless chain 7 is started and the plate group is put on standby. The first and second plate transfer bodies 8, 8' move toward the fixed plate 4 to receive the plate 2.

(3) When the first plate transfer body 8 passes over the handle portion 2a of the leading plate 2 of the standby plate group, the feed pawl 12 hits the plate handle portion 2a and falls down toward the movable plate 5 side. As the feed pawl 12 is lowered, the stop pawl 13 rises up against the biasing force of the torsion spring 26 via the idler 15.

(4) Feed claw 12 beyond the handle 2a of the top plate 2
is released from the tilting restriction and is urged toward the fixed plate 4 by the torsion spring 24, and the top plate handle 2
a and the next plate handle 2a, and its upright position is maintained by the feed pawl stopper 14 in a horizontal position. On the other hand, the stop claw 13, which was already in the upright position, hits the front surface of the handle portion 2a of the top plate 2 as the plate transfer body 8 advances, and an overload detection means (not shown) detects the resulting overload condition. Motor 6 is switched to reverse drive.

(5) Due to the reverse rotation of the motor 6, the plate transfer bodies 8, 8' begin to retreat from the fixed plate 4 side to the movable plate 5 side. Accordingly, the feed claw 12 of the first plate transfer body 8 hits the rear surface of the top plate handle 2a, and the top plate 2 is transferred toward the movable plate 5 side. Further, as the feeding claw 12 hits the back surface of the plate handle 2a, a gap is created between the front surface of the handle 2a and the stop claw 13, so that the stop claw 13 is biased by the torsion spring 26 during the plate transfer to prevent the fixing plate from moving. Maintain a prone position facing the side.

(6) When the transfer of the plate 2 continues until the tip pivot joints of the cloth lifting arms 2b, 2b connecting the leading plate 2 and the next plate 2 are at the predetermined position in front of the limit switch 40 (the leading plate 2 is in standby mode) (The distance from this transfer position to this transfer position is set to be larger than the distance between the plate transfer bodies 8 and 8'), a position detection means (not shown) detects this, and the motor 6
After stopping, the drive is switched to reverse rotation,
While leaving the leading plate 2 in the middle of the transfer path, the first and second plate transfer bodies 8, 8' reverse their advancing motions toward the waiting plate group side.

(7) When the first plate transfer body 8 approaches the next leading plate 2, the second plate transfer body 8' passes the plate 2 left in the middle and advances toward the fixed plate 4 side. At this time, the feed claw 12 hits the handle portion 2a and the movable plate 5
Although it is regulated to lie down toward the side, after passing the handle portion 2a, it returns to the upright position due to the bias of the torsion spring 24.

(8) The first plate transfer body 8 repeats the operations (3) to (5) above to engage the handle portion 2a of the leading plate 2 and transfer it to the movable plate 5 side. In parallel with this operation, the second plate transfer body 8' moves its feed claw 1
2 is the handle part 2 of the plate 2 left in the middle of the transfer path
This plate 2 is transferred to the movable plate 5 side by hitting the back side of the plate a.

(9) The plate 2 and the second plate transferred by the first plate transfer body 8
When the transfer progresses to a position where the tip pivot parts of the cloth hanging arms 2b, 2b connecting the plate 2 to be transferred by the plate transfer body 8' turn on the limit switch 40, the motor 6 is temporarily stopped. As shown in Fig. 13 (this figure shows the state in the middle of plate transfer being repeated multiple times)
The cloth vibration device 38 starts operating, and the plates 2, 2
The cloths 3, 3 in between are vibrated to remove the slag.

(10) When the cloth vibration treatment is completed, the motor 6 is restarted and the plate transport bodies 8, 8' move toward the movable plate 5 again.

(11) Each plate 2, 2 transferred by the plate transfer body 8, 8'
When the plate transfer progresses to the position where the end pivot joints of the cloth hanging arms 2b, 2b between them turn on the next limit switch 41, the motor 6 stops again and as shown in FIG. The cloth cleaning device 39 (showing a state in the middle of repeated plate transfer) starts operation, and its fountain nozzle 39a
The cleaning process for the cloths 3, 3 is carried out between the two cloths 3, 3.

(12) When the cleaning process by the cloth cleaning device 39 is completed, the motor 6 starts to drive in reverse again, and the plate transfer bodies 8, 8' switch to advancing operation, and the first
As shown in Figure 2, the operations (7) to (8) described above are repeated.

(13) After that, by repeating the operations (9) to (12) above, the two plate transfer bodies 8 and 8' share their respective transfer areas, and their reciprocating movements sequentially transfer the plates. ... from the fixed plate 4 side to the movable plate 5
Transfer to the side. During the transfer, cloth vibration processing and cloth cleaning processing are repeated.

(14) After the last standby plate 2 is transferred to the movable plate 5 side by the first plate transfer body 8, when the plate transfer bodies 8, 8' are switched to the forward/backward movement side, the plate is moved to the fixed plate 4 side. 2 is not on standby, the plate transfer bodies 8, 8' proceed as they are to the terminal end on the fixed plate 4 side, and each actuator 3 disposed there
2a and 37a have their own feed claw set levers 3.
1 and 31, and is restricted to a standing posture as shown in FIGS. 9 to 11. Therefore, the feed pawl stoppers 14, 14 are connected to the torsion springs 28, 2.
8, while the feed pawls 12, 12 are restricted to the downward position against the bias of the feed pawl stopper 1.
4, 14 is released, the feed pawl stopper 1 is biased by the torsion springs 24, 24.
4 and 14 side, and restricts the feed pawl stoppers 14 and 14 to a downward position. 1st
In the plate transfer body 8, the stop claw 13 is also in a prone position due to the bias of the torsion spring 26.

(15) When an overload detection means (not shown) detects an overload condition due to the contact of the feed claw set levers 31, 31 with the actuators 32a, 37a,
After the motor 6 is once stopped, it is switched to reverse drive, and each plate transport body 8, 8' begins to retreat toward the movable plate 5. At this time, the feed pawls 12, 12 and the stop pawl 13 are in a prone position, so when passing through the handle portion 2a of the plate 2 that has been transferred to the movable plate 5 side, the feed pawl 12, 12 and the stop pawl 13 are not obstructed by the handle portion 2a. can pass smoothly. Movable plate 5
When the plate transfer bodies 8, 8' move backward to the side terminal end, each actuator 32b, 37b disposed here has its own feed pawl set lever 3.
1 and 31 are hit, respectively, and each plate transfer body 8,
8' feed claw stopper 14, 14, feed claw 1
2, 12, stop claw 13, etc. are shown in Figures 6 to 8.
Return to the initial state shown in the figure.

In the plate feeding device having the above configuration, for example, when the plate is replaced with a different type and the gap width between the handles is changed, the screws 18 of each plate transporting body 8, 8'... By untying and removing the main body frame parts 9, 9 from the base frame parts 10, 10 directly connected to the endless chain 7, the feed pawls 12, 12 and the stop pawl 13 can be easily replaced.

Furthermore, in addition to replacing the pawl as described above, repairs can also be carried out extremely easily when the pawl becomes worn or other parts of the pawl engagement/disengagement mechanism break down.

Furthermore, instead of the configuration in which the two plate transfer bodies 8 and 8' share the transfer area and transfer the plate as in the previous embodiment, only the first plate transfer body 8 is used, and the entire area of the transfer path is covered. Even when it is desired to adopt the method seen in the conventional example in which one plate transfer body 8 is used for transfer, the change can be easily made by simply removing the main body frame portion 9 of the second plate transfer body 8' from the base frame portion 10. can.

According to the board feeding device of this invention, the feeding claw 1
2. A main body (body frame 9) having a stop pawl 13, a feed pawl stopper 14, and a slider 15 is directly connected to a conveyance belt (endless chain 7), and the main body (main body frame 9) is detachable. Since the plate transfer body 8 is formed with the base part (base frame part 10) to be attached, parts of the engagement mechanism such as the feed pawl 12 of the main body part can be easily replaced or repaired by removing the main body part from the base part. This has the effect of improving the workability of parts replacement and repair.
