Abstract

PURPOSE:To prevent dropping of the front end of a sheet material by providing a pair of sheet material holding members and a displacement means to the holding member, and supplying the sheet material into a press die tool in a state that it has been curved to so as to be projected upward or downward. CONSTITUTION:As for a sheet loader, holding members 8a, 8b are opposed and placed through a cylinder 6, in both ends of a supporting arm 7 which has been attached to a body arm 6 which can move forward and backward. When holding a sheet material 5, the members 8a, 8b are displaced to the sheet material 5 side by a cylinder 9, and side edges 5a, 5b of the sheet material 5 are slid along an inclined surface 10 of the members 8a, 8b and abutted on a detaining surface 11. As a result, the sheet material 5 is curved so as to be projected downeard, and in this state, is is supplied into a press die tool. In this way, dropping of the font end of the sheet material can be prevented.

(Prior art) Generally, when press working a sheet material, a sheet loader is used to clamp the rear end of the sheet material and feed the sheet material into a press die. In some cases, the front end of the sheet material sagged under its own weight and interfered with the press mold, making it impossible to set the sheet material. Therefore, conventionally, there was an inconvenience that the mold opening of the press had to be increased in consideration of the drooping of the tip of the sheet material.

(Structure of the Invention) The present invention includes at least a pair of holding members for holding a sheet material at both side edges thereof, and when the sheet material is held by the holding members, the sheet material is curved convexly upward or downward. According to the above structure, the sheet material held by the holding member is curved convexly upward or downward. As a result, the rigidity of the seal material is increased, and the sheet material does not sag. Therefore, even if the mold opening space of the press is made small, interference between the sheet material and the mold tool can be prevented.

FIG. 1 is a schematic front view of the entire press sheet material supply apparatus according to the present invention, in which 1 is a press in which the upper die 2 is elevated from the lower die 3 and the die is open, and 4 is a sheet loader. The sheet loader 4 has a main body arm 6 that can enter and retreat from the mold opening part of the press 1 in order to supply the sheet material 5 onto the lower die 3 of the press 1. provided horizontally extending along the direction of movement of
Support arms 7 extending horizontally at right angles to the extension direction of the arm 6 are attached to two locations, front and rear of the main body arm 6. A sheet material 50 is attached to both ends of the support arm 7.
Holding members 8a and 8b for holding the sheet material 5 by engaging with the sides i5a and 5b, respectively, are mounted so as to face each other via a cylinder 9, respectively. The holding members 8a, 8b hold the side edges 5a of the sheet material 5 by the action of the cylinder 9.

In the above configuration, the holding members 8a and 8b are now
As shown in the figure, when trying to hold the sheet material 5 by engaging with the side edges 5a and 5b of the sheet material 5 placed on the table 12, the holding members 8a and 8b facing each other The arm 6 moves so as to come into contact with both side edges 5a, 5b, but in this case, the distance between the holding members 8a, 8b is longer than the distance between both side edges 5a, 5b of the sheet material 5, that is, the width W of the sheet material 5. It's getting wider. When the two cylinders 9 operate to mutually displace the holding members 8a and 8b toward the sheet material 5 side, the side edges 5a and 5b of the sheet material 5 abut against the slopes 10 of the holding members 8a and 8b, Further, it reaches the locking surface 11 while sliding upward on the slope 10. The cylinder 9 still displaces the holding members 8a and 8b toward the sheet material 5,
As the distance W' between the locking surfaces 11 of both the holding members 8a and 8b becomes smaller than the width W of the sheet material 5, the sheet material 5 is pressed against both the locking surfaces 9, as shown in FIG. , curved convexly downward. It is clear that if the sheet material 5 is curved in this way, its rigidity will increase, so the sheet material 5 held by the arm 6 of the sheet loader 4 in this state will become straight when viewed from the first time. , it is possible to prevent the tip from hanging downward as shown by the dotted line in FIG.

In the above-mentioned embodiment, the sheet material 5 is curved convexly downward, but it may be curved convexly upwardly. Also, in the embodiment described above, the sheet material 5 is curved convexly downward.
is provided on the main body arm 6 of the sheet loader 40,
Depending on the shape of the holding members 8a and 8b, the number of pairs is not limited to two,
Even with a pair, it is possible to achieve this purpose.
