Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plate cradle that is used in an intermediate conveying device for feeding plate materials to the feed bar of a transfer press and is installed at a position where the plate material is delivered to the feed bar.

Conventionally, when transferring a plate from an intermediate conveyance device to the feed bar of a transfer press, a pedestal fixed to the press body was installed at the position where the plate was transferred to the feed bar, and a width adjustment device was installed on the pedestal in a direction perpendicular to the feeding direction of the plate. A pedestal with screws was provided. Therefore, the width of the pedestal can be adjusted according to the width of the plate material being handled, but since the adjustment screw protrudes long in the width direction, it interferes with the feed bar, which limits the adjustment length of the inner width of the feed bar. There were flaws.
In addition, since the height of the pedestal could not be adjusted, there was also a drawback that the length of the pedestal in the sheet material feeding direction was restricted due to the need to avoid interference with the feed bar, which was carried out while being held on the moving bolster when replacing the mold. Ta.

The purpose of the present invention is to eliminate these drawbacks, to make the width adjustment screw of the pedestal parallel to the feeding direction of the plate material, to have no protrusions in the width direction, and to have a large width adjustment amount of the pedestal.
The purpose of the present invention is to provide a board holder that is large enough to hold a board without interfering with the adjustment of the inner width of the feed bar or the loading and unloading of molds when exchanging molds, since the height can be adjusted. . Embodiments of the present invention will be described below with reference to the drawings.

1 and 2, a plate pedestal 2 is shown mounted on the bed 1 near the side of the press. At the bottom of the pedestal 2, a pedestal 3 fixed to the bed 1 is provided with a cylinder 4 operated by pressure fluid at the center thereof, and four vertically oriented guide rods 5 are erected around the cylinder 4. cylinder 4
At the upper part of the cylinder 4, there is provided a body 6 which is guided by a guide rod 5 so as to be freely raised and lowered and which is connected to the piston rod of the cylinder 4. At the center of the upper part of the machine body 6, a threaded rod 7 is rotatably supported parallel to the feeding direction of the plate material shown by the arrow A to be sent to the press.
The threaded rod 7 is provided with right-handed threads and left-handed threads from approximately the center toward both sides, and nut members 8 are screwed into the respective threads. A sprocket wheel 9 is fixed to one end of the threaded rod 7. In the center of the fuselage 6 is a brake motor 1 that can freely rotate in forward and reverse directions.
0 is stored and fixed. Brake motor 1
A sprocket wheel 11 is fixed to the output shaft of 0, and a sprocket wheel 9 of the threaded rod 7
A chain 12 is hung between the two. In addition, four rods 13 are provided on the upper part of the body 6 and are slidably guided in the body 6 horizontally at right angles to the threaded rod 7. A pair of receiving members 14, 14 are provided parallel to the threaded rod 7 on both sides of the threaded rod 7 to connect the tips of each of the rods.

3 and 4, a roller 15 is rotatably provided at the bottom of the nut member 8, and is guided by a groove 16 provided in the body 6 parallel to the threaded rod 7. It regulates the posture of (See Figure 1) A link 18 has one end pivotally attached to the tip of an arm 17 extending from the nut member 8 at right angles to the threaded rod 7 on both sides, and a link 19 has one end pivotally attached to the body 6. , a link 20 whose one end is pivotally connected to the receiving member 14, and four sets of link systems in which the other ends of these links 18, 19, and 20 are connected together by a pin 21 are provided. . An upper surface receiving plate 22 made of polyurethane is attached to the upper surface of the receiving member 14 and the body 6 to buffer and receive the plate material when the plate material is delivered. Also, the receiving member 1
Magnets 23 having the suction force necessary to temporarily fix the plate material placed on the upper surface receiving plate 22 are attached at two locations on the back surface of each of the magnets 4.

Next, we will discuss the effect. In FIGS. 1, 2, and 3, when the width of the plate material handled by the press changes, the brake motor 10 is started to change the spacing between the receiving members 14, 14 in accordance with the width of the plate material, and the brake motor 10 is moved in the required direction. Rotate. Sprocket wheel 1
1, 9 and the chain 12, the threaded rod 7 is rotated to move the nut members 8, 8 to the required positions. The nut members 8, 8 are moved toward or away from each other by the action of the right-hand thread and the left-hand thread of the threaded rod 7, and the link 19 is rotated about the pivot point of the fuselage 6 via the link 18, and the link 20 is rotated. Through the receiving member 14
can be adjusted by moving it in parallel to a desired position within the range shown by the solid line and the dashed-dotted line in FIGS. 2 and 3. The receiving member 14 has a rod 1 fixed thereto.
3 is guided by the fuselage 6, allowing for smooth movement.
The length of the rod 13 is such that its free end side does not interfere with adjusting the inner width of the feed bar (not shown).
The receiving member 14 and the rod 13 do not interfere with the feed bar, and the spacing between the receiving members 14, 14 can be adjusted over a very wide range. Note that after the brake motor 10 is stopped, the receiving member 14 is fixed and stable by the brake of the motor. Next, when replacing the mold, when carrying in and out while holding the feed bar on the moving bolster 24, the cylinder 4 is operated to shorten the piston rod, and the machine body 6 is lowered along the guide rod 5. Interference can be avoided by lowering the upper part and the receiving member 14 to a position lower than the feed bar.

As is clear from the above description, according to the present invention, since the threaded rod for adjusting the width of the receiving member of the pedestal is provided facing the feeding direction of the plate material, the inner width adjustment of the feed bar is not restricted. In addition, by providing a link system, the width adjustment amount of the receiving member can be increased, and since the machine body can be raised and lowered by a cylinder, interference with the feed bar can be avoided when changing molds. The effects and benefits are extremely large.
