Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a material plate feeding device that feeds a material plate wound into a coil to a processing machine while drawing it out from one end thereof.

This type of device has a structure that includes a holding means for holding a coiled material plate and a transfer path for pulling out and unfolding the material plate, but it is difficult to feed the material plate to a processing machine such as a press machine or a shearing machine. In order to achieve dimensional accuracy, it is necessary to provide a reservoir in the transport path in which the material plate is allowed to relax.

In other words, if the supply means for supplying the material plate to the processing machine, such as a pressure-contact type feed roller mechanism, slips between the material plate and the material plate, an error will occur in the feed dimension. It is undesirable for the material plate to be added to the material plate, and therefore, a storage section is provided in front of the supply means so that the weight of the material plate wound into a coil does not affect the supply means, and the material plate is stored in this storage section in a relaxed state. This limits the weight of the material plate acting on the feeding means.

However, since the storage section of the conventional device has a configuration in which a space sufficient to absorb the amount of loosening of the material plate is formed between the supply means and the holding means, it is necessary to maintain a large space between the material plate supply device and the processing machine. In the former case, there is a disadvantage of increasing the factory area; In the latter case, there were inconveniences such as a rise in equipment costs and difficulty in moving processing machines.

The above-mentioned storage section is necessary for both processing machines that feed material plates continuously and processing machines that feed material plates intermittently, but especially in the latter, the material plates stored in the storage section are necessary. Since the length of the tank becomes longer, it is necessary to increase the volume of the reservoir, which has the disadvantage of increasing the required installation area and installation cost.

The apparatus of the present invention aims to provide a material plate feeding apparatus that can eliminate the above-mentioned disadvantages.

The apparatus of the present invention will be explained below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes a base frame, holding means for rotatably holding a material plate 2 wound in a coil shape, such as a rotating frame 3, and the material plate 2. It is provided with a transfer path 4 which is drawn out from one end and unfolded, and a supply means such as a feed roller mechanism 5 provided at the delivery end of this transfer path 4.

The transfer path 4 is provided with an elevating frame 6, and the elongated material plate 2 is expanded onto the transfer path by the elevating frame 6.
' is supported while being curved in such a manner as to bulge upward.

The elevating frame 6 has a receiving member 61 for receiving the lower surface of the extending material plate 2', and a dossing cylinder device 62 attached to the base frame 1 to raise and lower the receiving member 61. 62, the receiving member 61 is always urged upward.

For example, the receiving member 61 is configured to have a curvature as shown in the figure, and with this configuration, it supports the extending material plate 2' while appropriately curving it in relation to its thickness. A straightening machine 7 having a function as a feeding means, for example, a feeding roller, is arranged between the straightening machine 1 and the extending material plate 2' pulled out from the rolled material plate 2 of the rotating frame 3 by the straightening machine 1. It is sent out toward the receiving member 61 of the elevating frame 6 while being corrected in shape.

The elevating frame 6, feed roller mechanism 5, and straightening machine 7 operate in relation to each other as described below.

First, in a normal case, the feeding operation of the feed roller mechanism 5 and the feeding operation of the straightening machine 7 are not linked, and the feeding operation of the straightening machine 7 is controlled by an upper detection means, for example, a switch 63, which detects the raised position of the lifting frame 6. The elevating frame 6 is controlled by a lower detection means such as a switch 64 for detecting the lowered position of the elevating frame 6, while the elevating and lowering movement of the elevating frame 6 is obtained by the tension applied to the extending material plate 2' by the feed roller mechanism 5.

For this purpose, the straightening machine 1 starts feeding the material plate by the detection operation of the lower switch 64 as shown in FIG. 3A, and also starts the feeding operation by the detection operation of the upper switch 63 as shown in FIG. 3B. The cylinder device 62 of the elevating frame 6 is configured to stop the extending material plate 2' and clamp and fix the material plate 2' on the receiving member 61. When a downward pulling force is applied to the material plate 2' between the straightening machine 1 and the feed roller mechanism 5, this force causes the material plate 2' to shrink from the state shown in FIG. 3B to the state shown in FIG. 3A, while being straightened. When the machine 7 restarts the material plate feeding operation and the material plate 2' is supplied, the setting is made so that the material plate 2' is pushed up and expanded from the state shown in FIG. 3A to the state shown in FIG. 3B. has been done.

In the above, the supply means, for example, the feed roller mechanism 5
is usually provided on the base frame 1 as shown in the figure, but depending on the case, a structure on the side of a processing machine, such as a plain machine, may be used.

Furthermore, it is desirable that the elevating frame 6 descends when the coiled material plate 2 has been drawn out, so that the end of the material plate is smoothly guided to the feed roller mechanism 5 without jumping up.

In this way, the device of the present invention is configured such that the material plate 2' is attached to the receiving member 61, which is always urged in the pushing up direction by the pushing up cylinder device 62.
is spread out and placed on the material plate 2', and the receiving member 61 is lowered by the tension generated in the material plate 2' by the supply means, for example, the roller mechanism 5, as the material plate 2' is supplied, and the feeding means, for example, the straightening machine 1 is operated. Since the structure is such that the receiving member 61 is raised by the attenuation of the tension of the material plate 2' as the material plate 2' flows out, and the operation of the delivery means is stopped, the following effects can be expected.

Automatic control is easy because the receiving member 61 is raised and lowered by the tension generated in the material plate 2' and the delivery means is controlled thereby.

Since the cylinder device 62 can easily make the pushing blades uniform during the lifting and lowering process, the material plate 2' can be lifted and lowered with a substantially constant pressing force, and therefore the feeding operation of the feeding means can be maintained accurately. I can do things.
