Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an improvement in a reciprocating filter plate feeding device for a filter press, and particularly to a reciprocating device for smoothly feeding a door plate to one side while preventing feed delays in the feeding device. This invention relates to a driven filter plate feeding device.

Conventional technology A feed pawl and a stop pawl of a door plate feeding device of a filter press are installed opposite to each other on a moving base, the base is moved by a motor toward the door plate to be fed on a rail, and the feed pawl is moved toward the door plate to be fed. Rotate the grip part in the opposite direction to the feeding direction and bring the stop claw into contact with the feeding direction side of the door plate to stop the base from moving, and then reverse the movement of the base to feed the door plate. The direction is reversed and the door plate is driven to one side with the feed pawl hooked to the door plate grip part, and the running direction of the base is reversed again and both pawls are detached from the door plate grip part and the base is moved. There is a door plate feeding device that travels toward a second door plate to be sent and sequentially sends the door plates to one side. The reciprocating movement of the movable base is driven by connecting an endless chino to the base or by mounting a motor on the base.

Problems to be Solved by the Invention In a device in which a motor is mounted on a movable base, when the base moves in reverse, slip may occur between the base and the rail, causing the motor to idle.

Also, if the machine is driven by an endless chain, there will be a delay in reaction time. In any of the above cases, there is a drawback that it is difficult to quickly control the drive of the motor.

The present invention aims to solve the above-mentioned drawbacks of the conventional door plate feeding device, and it is possible to quickly reverse the movement of the moving base, eliminate the delay in feeding the door plate, and smoothly engage and disengage the pawl from the door plate. The present invention provides a reciprocating door plate feeding device for a filter press that can safely feed the filter press.

Means for solving the problem, that is, the present invention is a filter plate feeding device that has a moving base with a feed claw and a stop claw and is driven back and forth, and transmits an ON-OF multiplication signal by running the moving base. A signal transmitter that transmits either an ON or OF signal when the movable base stops moving when the door plate is engaged or detached, and an ON-OF multiplied signal from the signal transmitter is input to control the motor in a certain direction. A filter press characterized in that it is equipped with a rotational drive converting device for the motor that continues the rotational drive and changes the rotational drive direction of the motor after inputting either an ON or an OF signal for a set time. This is a reciprocating door plate feeding device.

In addition, the above-mentioned door plate feeding device is provided with a reciprocating actuator at the extension end extending from the movable base toward the door plate, a mounting base for the feed pawl is connected to the actuating device, and the intermediate portion is pivoted to the mounting base. Arrange the two feeding claws in parallel with an interval greater than the width of the filter plate gripping part.
Fix the stopper of the feed pawl to the above-mentioned mounting base at a position away from the shaft fulcrum of the feed pawl, and connect both pawls with a spring on the opposite side of the end of the feed pawl that engages and disengages from the filter plate gripping part. The mounting base is reciprocated by a reciprocating device to engage and disengage the feed pawl from the door plate gripping portion.

Operation In the door plate opening step, when the moving base moves toward the first door plate to be sent, an ON-OF multiplication signal is continuously transmitted and this signal is input to the reciprocating drive motor side. When one claw of the base hits the filter plate gripping part, the base stops and the ON-
The signal changes to either the OF multiplication signal ON or OF, and this signal is input to the reciprocating drive motor side. When one of these signals continues for a set period of time (for example, 0.5 seconds), the rotational driving direction of the motor is reversed, and the moving base moves in the same direction as the moving direction, with the other claw retaining the first filter plate. Run in the opposite direction. When the movable base moves, the ON-OF signal is continuously transmitted as described above.

When the movable base sends the door plate to one side of the opening gap, the base stops traveling, and the ON-OF double signal turns ON or OF.
The signal changes to one of the following. When one of the signals continues for a set period of time, the direction of rotation of the motor is reversed, and the base moves toward the second filter plate, where the mold is to be sent away from the door plate. When the base moves in the same manner, the ON-OF signal is continuously transmitted, and each door panel is sent to one side one by one in the same manner.

EXAMPLES The present invention will be explained in detail with reference to the drawings. Fig. 1 is a side view of a filter press according to the present invention, in which signal 1 is the front and rear machine frames, 2 is the side plate connecting both machine frames, 3 is the filter plate hung on the side plate 2, and 4 is the filter plate group. A tightening device, 5 is a column erected on the machine frame on the tightening device side, 6 is a column erected on the other machine frame (fixed plate), and 7 is a column installed between the above two columns 5 and 6. A running rail, 8 a filter plate feeding device consisting of a moving base, 9 a reciprocating drive motor, and 10 a filter press operation panel. The tightening device 4 is driven backward to separate the movable plate 11 from the filter plate group, thereby creating a certain gap between the movable plate 11 and the first filter plate 3-1 to be sent. The feeding device 8 is shown enlarged in FIGS. 2 and 3.

Figure 2 shows the front view of the filter plate feeding device and the upper half of the filter plate;
FIG. 3 is a side view of the feeding device and the upper half of the filter plate shown in FIG. 2, viewed from the left side. That is, the reciprocating drive motor 9 is placed on the top plate 12 which is a movable base of the feeding device 8, and the switch 13 is fixed on the top plate 12 with a support plate 14 in line with the motor. Reference numeral 13a is a conductive wire connected to the operation circuit of the rotary drive conversion device located within the operation panel 10. Above switch 13
A rotary protrusion 15 is rotatably supported by a shaft 16 directly below the rotary protrusion 15 .

The middle of the shaft 16 is supported through a stand 17 fixed on the top plate 12, and a rotor 18 is attached to the other end of the shaft 16.

The switch 13 and the rotating protrusion 15 constitute a signal transmitter for the drive device. The rotor 18 rotates and travels on the rail 7. Also, bearings 19, 19 are provided on the lower side of the top plate 12.
and pass the rotating shaft 20 through it. A chino 21 is placed between the pulley on the rotating shaft 20 and the pulley of the motor 9.

Further, rollers 22.22 are attached to both ends of the rotating shaft 20, and these are mounted on the running path inside the rail 7.7, and the feeding device 8
travels back and forth on rail 7. As shown in an enlarged view in FIG. 4.5, the rotary protrusion 15 includes an annular portion 15a (base) that is fitted into and fixed to one end of the shaft 16, and an annular portion 15a.
It consists of a bolt-like projection 15b with a threaded portion screwed into a screw hole drilled on the outer periphery of the bolt. On the garden side, there are 4 bolt-shaped protrusions 15

When it becomes N, the abutment i5b moves away from the switch 13 and turns OF.
This is how it should be. When the ON-OF multiplier signal is continuously input to the motor 9 side, the motor 9 continues to rotate in the same direction, and when the feeding device is stopped, the bolt-like protrusion 15b continues to rotate for a predetermined period of time, for example, 0.5 seconds. When the bolt-like protrusion 15b stops, an ON signal is input to the motor 9 side if the stop position is below the switch, and an OF signal is input to the motor 9 side if the bolt-shaped protrusion 15b stops at a position outside the switch 13 position. −
The rotational drive of the motor 9 is reversed by the input of one signal. The bolt-like protrusion 15b described above may be formed into a rotating brush shape. In addition, the head 15C of the bolt-shaped protrusion 15b is rotated, and each head 15C is shaped like an annular @'H15a.
The distance to the switch 13 can be easily adjusted by adjusting the distance from the switch 13 to the same height. Further, the distance between the bolt-shaped protrusion 15b and the switch 13 may be adjusted using a screw 14a provided on the support plate 14.

Although the above switch 13 is an example of a photoelectric switch, it goes without saying that other switches having the same function can be used.

Next, the feed claw device will be explained. In FIG. 2.3, a signal 23 indicates a mounting plate provided below the rotating shaft 20 and parallel to the top plate 12. The mounting plate 23 and the top plate 12 are connected by connecting plates 24 and 24.

The furnace cloth hanging rod 45 and the furnace cloth hanging rods 46 and 47 are rotatably connected by links 48 and 49, respectively. The furnace cloth 44 covers the filter plate surface, and forms a transit chamber into which the stock solution is placed between the furnace cloth 44 and the furnace cloth covering the adjacent filter plate.

In the reciprocating filter plate feeding device in the filter press configured as described above, in the plate opening process, first the operating panel 10
The operation circuit inside is opened, the tightening device 4 is moved backward, the movable plate 11 is separated from the P plate group, and an open gap is created between the movable plate 11 and the first filter plate 3-1 to be sent. Open it (Figure 1). Next, when the reciprocating drive motor 9 of the filter plate feeding device 8 in the standby position is energized, the feeding device 8 moves its rotating shaft 2.

When the rotation of the rotating protrusion 15 stops for a set time (approximately 0.5 seconds), the drive circuit of the motor 9 is switched and the rotation of the motor 9 is reversed. By reversing the motor 9, the feeding device 8 runs on the rail 7 in the filter plate feeding direction, and the rotor 1

The claw mount 31 and the claws 32 and 33 connected to the filter plate 3-1 are separated from the grip portion 42 of the filter plate 3-1 (FIG. 12). By driving the motor 9 in reverse quadrature rotation, the feeding device 8 moves its claws away from the filter plate gripping portion and moves toward the second filter plate 3-2 to be fed next. During this travel, the elevating piston 29 is driven downward to lower the pawl mounting base 31 and return both pawls 32 and 33 to their original height positions. Figure 13 shows the claw 32.3 of the feeder 8.

In addition, in FIG. 2.3, the number 60 is a cleaning water injection pipe with a large number of nozzles, 61 is a mounting base on which the injection pipe 60 is rotatably attached, and 62 is a transverse rail fixed to the surface of the transverse plate 26. It consists of two rails, top and bottom. Reference numeral 63 denotes a roller that is pivotally supported on the mounting base 61 and is capable of running within the two transverse rails 62 mentioned above. Reference numeral 64 denotes a chain, which is hung around sprockets 65 and 65 that are pivotally supported at both ends of the transverse plate 26, and the inside thereof is connected to the shaft 66 of the roller 63. A drive motor (not shown) is attached to the shaft of one sprocket 65.

Further, 67 is an inclined plate that rotates the injection pipe 60 from above the door plate and allows it to hang down along the door plate surface. That is, the inclined plate 67
A roller 69 is pivotally supported at the tip of the mounting base 61 on the inclined surface 68 of the
When the cheno 64 is driven horizontally, the injection pipe 60 hangs down from above the door plate along the filter plate surface due to its own weight. The injection tube 60 in its hanging state is shown in dashed lines in FIG. From this position, the injection pipe 6 is continuously driven by the traversal drive of the Cheno 64.

On the other side, a traverse switching device such as a limit switch operates to drive the chino 64 in reverse, moving the injection pipe 60 from the door plate surface to its original standby position above the door plate and storing it. The cleaning device consisting of the injection pipe 60 configured as described above sends the tightened door plate in the opening direction again after discharging the cake, and in the cleaning process in which the door plate is washed, the feeding device is moved from the standby position to remove the filter plate 3. A cleaning operation is performed by spraying cleaning water from a nozzle onto the covering P cloth 44 surface. Reference numeral 70 indicates a diaphragm of a P cloth vibrator (not shown), which vibrates the furnace cloth hanging rod 45 with a predetermined amplitude. Therefore, each time the filter plates are opened, the injection pipe can be quickly moved between the door plates to be put in and taken out, and the cleaning time can be further shortened.

Effects of the Invention According to the present invention, it is possible to quickly and reliably stop the rotation of the drive motor and change the direction of rotation by running and stopping the filter plate feeding device, thereby preventing the feeding device from slipping on the running rail. Alternatively, the door plate can be safely sent by smoothly engaging and disengaging the feed pawl from the bifurcated door plate without delay in switching reaction time.
