Description

[Detailed description of the invention] <Industrial field of application> The present invention is a material plate feeding device for a press machine, which is equipped with an uncoiler device and a material plate feeding device installed opposite to this device through a material plate storage space. It is related to the device.

<Prior art> In order to unroll and set a material plate wound in a coiled form, that is, a coil material, in a conventional feeding device of this kind, the coil material is first lifted by a crane and fitted into the support frame of an uncoiler device. Next, a presser is pressed against the outer periphery of the coil material to suppress natural unwinding of the coil material, and presser arms are brought into contact with both side planes of the coil material to prevent unwinding of the coil material, Furthermore, the material plate is unwound and pulled out from the coil material set in the uncoiler device in this manner, and the tip of the material plate is passed through the material plate storage space to match the operation of the material plate feeding device, for example, the material plate press machine. Then, the material plate is guided to an intermittent transfer mechanism that transfers it intermittently, or a leveler device that feeds the material plate while straightening it, and finally the tip of the material plate is transferred to a receiving means of the material plate feeding device, such as a feed roller, etc. Requires a step to insert into.

<Problems to be solved by the invention> In the above procedure, in order to set the material plate on the material plate feeding device, the operator lifts the tip of the material plate and places it on the plate receiving surface of the catenary section, etc. Next, the tip of this material plate is passed between the feed rollers, and the material plate is positioned by side guides installed opposite to each other in the width direction of the material plate, and then the feed rollers are closed to clamp the material plate. Since the work is demanding, there is a risk of frequent back pain or injury to the worker, and there is also the problem of poor workability and long downtime of the press machine.

In order to eliminate this manual work of setting the material plates, a mechanism has been proposed that receives the material plate pulled out from the coil material from below and lifts it so that its tip reaches the feed roller position. This method is disclosed in JP-A-60-71421 and JP-U-61-127819.

However, in such a mechanism, since the mechanism for lifting the material plate is automated, the structure is complicated and the price is high, so that it is not suitable for a general material plate feeding device.

<Means for solving the problem> In the device of the present invention, as shown in FIG. , this receiving plate surface 23
A guide frame 22 is provided in parallel above with a sheet passing space S in between, and a guide plate 60 is provided in the material plate storage space 40 formed in front of the material plate feeding device 20. There is.

The guide plate 60 is formed into a curved shape with an open upper part so that the material plate 32 flowing out from the uncoiler device 10 is raised and raised with its tip facing the receiving plate surface 23, and the tip portion 61 is raised and raised. ing.

On the other hand, the guide frame 22 has its tip 22
1 is made so as to protrude from the tip portion 61 of the guide plate 60 toward the uncoiler device 10,
Therefore, the threading space S is the tip portion 61 of the guide plate 60.
It opens directly above.

<Function> Since the device of the present invention is as described above, the tip of the material plate 32 sent out from the uncoiler device 10 is guided by the tip portion 61 of the guide plate 60 and stands up, as well as downwardly as shown by the chain line in FIG. The sheet is fed into the sheet passing space S, and thereafter guided toward the feed roller mechanism 24 by the guide surface 222 of the guide frame 22.

Therefore, the material plate 32 can be automatically set on the feed roller mechanism 24 by opening the feed roller mechanism 24 of the material plate feeding device 20 in advance and closing it after passing the material.

<Example> Fig. 1 is a front view of the proposed device, showing an uncoiler device 10 and a leveler device 2 as a material plate feeding device.
There is a union with 0.

The uncoiler device 10 is constructed to include a support frame 11, a pinch roller mechanism 12, a rotating presser 13, and a side presser mechanism 14.

As shown in FIG. 2, the support frame 11 includes a support piece 1 that is extendable and retractable around a rotating shaft 111 rotated by a drive motor 15 serving as a material plate transfer means.
12 are fixed in the radial direction, and this support piece 1
12 is brought into pressure contact with the inner diameter surface 31 of the coil material 30 wound into a coil shape to support the coil material 30, and the coil material 30 is moved by the drive motor 15.
It is constructed so that it can be rotated in the direction of unwinding, that is, in the counterclockwise direction in FIG.

The pinch roller mechanism 12 is configured to pinch the material plate 32 flowing out from the outer periphery of the coil material 30 when it is unwound, and send it out with a constant torque toward the material plate storage space 40. For this purpose, a pair of rollers, an opening/closing means for opening and closing these rollers, for example, a handle 121 for moving one roller toward and away from the other roller, a spring 123 for urging the movable roller 122, and a spring 123 (not shown) for urging the movable roller 122 are provided. It is equipped with a drive means such as a torque motor, etc.

In this embodiment, the pinch roller mechanism 12
is provided as a material plate transfer means that cooperates with the support frame 11, but in some cases, the pinch roller mechanism 12 may be configured to unwind the coil material 30. In this case, The support frame 11 is not provided with a drive motor 15.

The rotating presser 13 prevents the coil material 30 from loosening by pressing against the outer periphery of the coil material 30 with a constant pressing force, and is applied with a pressing force by a driving means such as an air cylinder 131. It is structured like this.

The side holding mechanism 14 includes a pair of stoppers 141 and 14 that press against both side planes of the coil material 30.
2, and is configured such that the coil material 30 is fixed on the support frame 11 with these stoppers.

Of these stoppers 141, 142, the rear stopper 141 is set before the coil material 30 is attached, and the front stopper 142 is set after the coil material 30 is attached.

The material plate storage space 40 is formed below the support frame 11 so as to loosely retain and store the material plate 32 sent out from the pinch roller mechanism 12, and the height position of the material plate 32 is adjusted. A drive control stage 50 is provided which is configured to control the operation of the support frame 11 and the pinch roller mechanism 12 by sensing. The drive control means 50 is
In the embodiment, the pinch roller mechanism 1 is
2 and the detection switch 51 that drives the material plate 3.
A rotary piece 52 rides on the material plate 32 and moves up and down depending on the position of the material plate 32, and closes the detection switch 51 when it goes up and opens the detection switch 51 when it goes down.
and when the detection switch 51 is closed, the material plate transfer means of the uncoiler device, that is, in the embodiment, the drive motor 15 of the support frame 11 and the pinch roller mechanism 12 The torque motor is started to transfer the material plate 32, and when the detection switch 51 is opened, the drive motor 15 and the torque motor are stopped to stop the transfer of the material plate 32. .

Such a support frame 11 and pinch roller mechanism 12
It is not necessary for the cooperative operation with the pinch roller mechanism 12 to be precisely synchronized; for example, it may be better to stop the torque motor of the pinch roller mechanism 12 a little later than the stop of the drive motor 15.

The material plate feeding force of the pinch roller mechanism 12 is set to be weak relative to the rotational force of the support frame 11, and the pinch roller mechanism 12 is set to such an extent that it cannot rotate the coil material 30 by itself. ing.

That is, the pinch roller mechanism 12 merely sends out the unwound material plate 32 toward the material board storage space 40, and does not unwind the coil material 30.

Leveler device 20 as the material plate feeding device
This is for drawing in a material plate 32 from a material plate storage space 40, straightening it, and feeding the straightened material plate to a press machine. It is configured.

The guide frame 22 is installed to face the receiving plate surface 23 of the catenary section 21 across the threading space S, and the receiving plate surface 23 is connected to the receiving rolls 231, 23.
It is made up of 1.

Closer to the press machine than the receiving plate surface 23 of the catenary section 21 is a feed roller mechanism 24 that can be opened and closed manually, that is, a feed roller mechanism provided in the leveler device 20 in the embodiment.
Furthermore, in front of this feed roller mechanism 24,
Normally, as a component of the catenary section 21, means for positioning the material plate, such as side guides 25, 25, which are opposed to each other in the width direction of the material plate 32, are provided.

The guide frame 22 is disposed above the receiving plate surface 23 so as to guide the tip end of the material plate 32 guided by the guide plate 60 provided in the material plate storage space 40 into the plate passing space S. It is configured.

For this purpose, the guide frame 22 has its tip 2
21 is made above the tip portion 61 of the guide plate 60 so as to protrude from the tip portion 61 toward the uncoiler device, and the receiving plate surface 2 is made so as to smoothly guide the material plate 32 to the feed roller mechanism 24.
The guide surface 222 facing 3 is made into a curved surface.

The guide plate 60 is the pinch roller mechanism 1
The material plate 32 sent out in step 2 is guided and the tip thereof is made into a curved shape with an open upper part so as to rise toward the guide surface 222 of the guide frame 22, and the tip part 61 is made to stand up. The plate passing space S is made to open directly above the tip portion 61.

In this embodiment, the material plate 32 initially drawn from the coil material 30 is attached to the pinch roller mechanism 12.
The sheet is sent out and advances along the guide plate 60, and then stands up from the guide plate 60 and is captured by the guide surface 222 of the guide frame 22, thereby being guided into the sheet passing space S.

Therefore, this material plate 32 is attached to the side guides 25, 2.
5, the material plate 32 is passed through the feed roller mechanism 24 which has been opened in advance, and the feed roller mechanism 24 is closed after passing the material.
is set in the feed roller mechanism 24.

In the above, if the guide frame 22 is constructed so that its tip side can be rotated up and down to change the entrance width of the sheet passing space S, the material sheet 32 can be easily accepted. In addition, as shown in FIG. 3, a link mechanism 224 driven by a cylinder mechanism 223 is provided on the guide frame 22, and a guide such as a roller 225 is provided at the tip of the link mechanism 224. Due to the movement of the roller 225 due to rocking, the material plate 32 enters as shown in the solid line.
The traveling direction of the vehicle may be corrected by forcibly deflecting it as shown by the chain line.

<Effects of the invention> As described above, the present device allows the material plate 32 drawn out from the coil material 30 to be set in a material plate feeding device such as a leveler device without the operator lifting it.
Compared to the conventional work that requires supporting the weight of the material plate manually, the work of spreading the material plate becomes much easier and can be done quickly. Since it can be constructed with only the fixed guide frame 22 provided on the feeding device and the guide plate 60 facing it, the structure is simple and the manufacturing cost is low.
