JPS60179105A - Process for applying claw hook of hooking device for opening filter plate in plate filter - Google Patents

Abstract

PURPOSE:To open a filter plate securely and to prevent the opened filter plate from being closed again in a hooking device for opening a filter plate by erecting a claw hook interlocking with a push claw hook. CONSTITUTION:A claw box is moved in a direction for closing a filter plate by a chain 12 and a push claw hook 1 is fallen down by colliding with a supporting piece Ea of a filter plate. Thus, an engaging part 7a of a torsion spring is dropped and an engaging part 7b is raised to erect an engaging claw hook 2. Then, when the engaging claw hook 2 collides with the supporting piece Ea, the collision is sensed to cause reverse revolution of a motor and the claw box is moved in a direction for opening the filter plate. The push claw hook 1 pushes the supporting piece Ea and the filter plate is opened. When the filter plate is moved to an end of an opened filter plate, the resistance of the end is sensed and the motor is driven reversely again and the claw box is moved in a closing direction of the filter plate. In this stage, the engaging claw hook 2 collides with the supporting piece Ea of the opened filter plate and falls over.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for operating a pawl device for opening a door plate in a p-plate type p-pass machine.

As shown in Fig. 1, the conventional method for opening a door plate using a pawl device involves a push pawl 1' and a mold 2' that are biased to rotate upright by a spring.
are provided on the pawl surfaces facing each other, and the pawl surfaces are connected to a chino and run on a rail, and the support piece of the door plate is pushed by the pushing pawl 1' to open the door plate.

However, the door plate is pushed and moved by the push claw 1',
Since it hits the previously opened P plate or P frame and stops, the claw surface and the door plate immediately move in the closing direction due to the reaction of this stop. At this time, the mold 2' may hook the opened door panel again, and in order to open the secondary door panel, the claw surface moves in the closing direction, and the hooked door panel is returned to the closing direction again. become. Although such a situation is extremely rare, it will interfere with the automatic door opening operation. This is because the mold 2' is independently biased to stand up by the spring.

The reason for this is that the mold 2' always stands up when it is not in contact with the support piece of the door plate.

Therefore, the present invention provides a method of raising the door by linking the operation of the mold to the push pawl, which allows the door to be opened reliably and the door to be opened smoothly without having to return the opened door. be.

Hereinafter, details of the present invention will be explained with reference to the drawings.

First, the plate-opening pawl device shown in FIGS. 2 to 4 will be described. K is a pawl surface that accommodates a pushing pawl 1 and a mold 2 supported by a pin 6.4 facing each other.

One end of a tension spring 5 is locked to the lower end of the pusher claw 1.
By locking the other end of the spring 5 to the protrusion 6 inside the claw surface, the push claw 1 is always urged to stand up and rotate.

A torsion spring 7 serving as a seesaw material as shown in FIG.
a under the pressing claw 1, and the protruding engaging portion 7b at the other end.
is placed below this mold 2.

That is, the pressing claw 1 and the mold 2 are placed on the retaining portions 7a and 7b, respectively, and positioned in a seesaw shape. Reference numeral 9 designates a movable lid of a conventional upright mechanism, which serves to prevent the push-up claw 1 from standing up by pressing against the protruding body of the pusher and moving above the claw surface. 2a is a spring protruding from both sides of the mold, 10 is a wheel on the claw surface, 11 is a rail, and 12 is a chain lever of a traction device (not shown), which is the claw surface K.
It is connected to.

Next, to explain the present invention, first, as shown in FIG.
2, the claw surface K moves in the closing direction, and the pushing claw 1 hits the support piece Ea of the door plate and falls down. As a result, the engaging part 7a of the torsion spring 7 goes down and the other engaging part 7b goes up, so that the mold 2 is made to stand up. Then, the pushing claw 1 separates from the support piece Ea and is biased to stand up, and the mold 2 hits the support piece Ea and detects the resistance force, and the motor (not shown) reverses, so that the claw surface K moves in the direction of opening the plate. That's what I do. As a result, the push claw 1 pushes the support piece Ea to open the door plate as shown in FIG. At this time, since the push claw 1 stands up, the spring 7 also rotates back to its original position, but the mold 2
Since a is lightly clipped and locked between the inner surfaces of the claw surface, the projecting piece Ea is maintained in an upright state without falling down, and the protruding piece Ea
The board will be opened across the board. When the door plate moves to the opening end, the resistance force is detected and the motor reverses again to move the claw surface K in the closing direction. At this time, the mold 2 collides with the support piece Eb of the previously opened door plate and falls down, so there is no problem in moving to the claw surface (see FIG. 8). A characteristic feature of this example is that the mold 2 is not urged to stand up by a spring, so that the mold 2 does not catch the support piece Ea of the opened door plate and move. After repeating this operation and opening all the door panels, the movable cover 9 hits the protrusion 16 at the end in the closing direction and moves, so the movable cover 9 forcibly pushes the pusher claw 1. As a result, the mold 2 hits the machine body via the spring 7, causing the motor to reverse, and the claw surface K moves in the direction of opening the plate in the state shown in FIG. At this time, this mold 2 hits the support piece E of the opened door panel.
will fall down and move against the spring 7 (see Fig. 10). Then, the movable lid 9 hits the protrusion 14 at the end in the plate opening direction and moves back to its original position.The push claw 1 rises and hits the body (see Figure 11), and the motor is stopped to stop the movement on the claw surface. It is. This allows the claw surface K to be used for the next opening operation.
is in a waiting state at the end in the plate opening direction.

As described above, according to the present invention, the operation of opening a door plate using a claw is the same as in the conventional method, but since the mold 2 stands up only when the pushing claw 1 is in a lowered state, the opened door plate can be hooked and returned again. This situation will not occur.

In this example, the mold is erected using an elastic torsion spring as the seesaw material, but the present invention is not limited to this. For example, as shown in FIG. 12, a leaf spring 15 may be used as the seesaw material. Alternatively, as shown in FIG. 16, a piece of steel 16 made of an inelastic material is fixed to the pin 17 as a seesaw material, and the pin 17 is inserted between the long holes 18 in the claw surface, and the movable lid 19 and the pin 17 are connected by the arm 20. They may be connected, so that the mold 22 stands up when the pressing claw 21 falls down,
In addition, when the movable lid 19 moves and the pusher claw 21 collapses, the bottle 17 also moves, so even if the steel piece 16 rotates, its engaging end enters the cutout groove 22a of the mold 22 and comes into contact with it. 14 without pushing up the mold 22). Therefore, the claw surface K can be moved to the end in the plate opening direction without any hindrance for the next plate opening.

Also, seesaw material may be combined with the pressing claw and the mold.

In this case, the mold will fall down while the pusher claws are upright, but this will not hinder the opening of the p-plate. Further, there is also an appropriate means for moving the claw surface to the end in the opening direction in preparation for the next opening, and an arbitrary means for lowering the pushing claw and the die. In short, the present invention provides a pressing pawl that can be rotated to fall down and stand up, and a mold facing each other on the nail surface, and the pressing pawl is biased to stand up and rotate with a spring or the like, and the pressing pawl presses and moves the support piece of the P plate. In the claw operation method of the claw device for opening the plate, a seesaw material is interposed between the pusher claw and the die, and the back of the pusher claw hits the support piece of the p plate as the claw surface moves in the closing direction. This is a pawl actuation method of a pawl device for opening an R-plate in a P-plate type p-chip machine, characterized in that the push pawl is rotated to fall down and at the same time the mold is raised up by a seesaw material.

Therefore, according to the present invention, the mold stands up when the pushing claws are in a laid down state, so that the mold does not catch the opened p-plate and return it in the closing direction, making the opening operation better. This is an excellent effect in terms of automatic plate opening.
