DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet feeding device for feeding and feeding a sheet in a posture inclined at a required angle to various processing units disposed downstream. Things.

[0002]

2. Description of the Related Art A rotary die cutter is preferably used as a means for punching a sheet of corrugated cardboard (sheet-like material) into a required shape and forming a blank or the like as a base material of a box that can be assembled and disassembled. Have been. This rotary die cutter is provided with a die cylinder in which a die in which a punching blade of a required shape is planted on a curved board is detachably wound, and a die cylinder is disposed with its axis parallel to the die cylinder. And an anvil cylinder wound with an anvil made of a urethane material that receives the anvil in a biting state. The two cylinders are driven in mutually opposite directions by an external drive source commonly connected via a gear train. On the upstream side of both cylinders, there is provided a sheet feeding device including a sheet feeding table on which a large number of cardboard sheets are stacked and placed, and a kicker that moves on the table back and forth in the sheet feeding direction. At this timing, the kicker moves forward and sends out the cardboard sheets one by one from the lowermost layer toward the downstream side. Then, the corrugated cardboard sheet horizontally supplied from the sheet feeding device between the two cylinders is pressed forward by the punching blade and the anvil and sent forward, and in this process, the sheet is punched in a required shape (so-called “soft cut”). ) Is applied.

[0003]

In the rotary die cutter, the axis of the die cylinder is set to be parallel to a reference line orthogonal to the sheet feeding direction. Therefore, the horizontal punching blades arranged on the die for applying the horizontal punching line parallel to the reference line to the corrugated cardboard sheet are also set to be parallel to the reference line. When punching a corrugated cardboard sheet with the horizontal punching blade set in this way, the horizontal punching blade abuts the sheet at one time over its entire length. Works. When such an impact load is repeatedly applied to the two cylinders, there is a problem that the service life of the bearings and the like of the two cylinders is shortened. Therefore, measures have been taken to increase the mechanical strength of the bearings and the like, but in this case, the apparatus is disadvantageously increased in size and the manufacturing cost is increased. Further, the above-mentioned impact load is also applied to the lateral punching blade of the die, and the service life of the blade may be shortened or the blade may be damaged.

[0004] In the rotary die cutter, in order to apply a ruled line for folding a box or the like to a corrugated cardboard sheet together with punching, a die having a ruled blade for the ruled line planted on the curved board may be used. At this time, it is pointed out that a large impact load is applied to the horizontal ruled blade for forming a ruled line (horizontal ruled) parallel to the reference line as in the case of the horizontal punching blade, and the ruled line is strongly inserted and the ruled line is broken.

In order to cope with the above-mentioned problem, a horizontal punching blade, a horizontal ruled blade, and the like disposed on a die cylinder having an axis set in parallel with a reference line are inclined by a required angle with respect to the reference line. Proposals have been made to tilt each blade with respect to the reference line by disposing or by tilting the axis of the die cylinder itself by a required angle with respect to the reference line.
According to this method, each blade does not abut against the corrugated cardboard sheet at one time over its entire length, but gradually abuts from one end to the other end. It can be reduced.

When the horizontal punching blade and the horizontal ruled blade are inclined with respect to the reference line as described above, it is necessary to supply the corrugated cardboard sheet between the die cylinder and the anvil cylinder in a corresponding inclined posture. However, there is no specific proposal of a paper feeder capable of supplying a corrugated cardboard sheet in a proper inclined posture.

[0007]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above-mentioned problems inherent in the prior art, and has been proposed in order to suitably solve the problem. An object of the present invention is to provide a sheet-like sheet feeding device that can be supplied to a processing unit on the downstream side in an appropriate inclined posture.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems and appropriately attain the intended purpose, the present invention has a structure in which various kinds of processing units arranged on the downstream side are stacked on a sheet feeding table.
