自動給紙する装置に関するものである。BACKGROUND OF THE INVENTION The present invention relates to a method for unwrapping an external paper enclosing a paper roll such as newsprint paper by mechanical means without manual operation. The present invention relates to an apparatus for automatically feeding paper.

移動操作可能に取付けていた。2. Description of the Related Art Japanese Patent Application No. Hei 4-15122 discloses a conventional technique for mechanically unsealing and cutting an exterior paper enclosing a web.
No. 3, which is disclosed in the specification and the drawings, wherein an exterior paper opening head is vertically provided on a moving body which is positioned above the exterior paper enclosing the horizontally placed web and runs in the axial direction of the web, and In the opening head, an exterior paper cutting guide member is elastically suspended so as to be swingable downward, and an exterior paper cutting cutter is mounted to be movable in the front-rear direction.

なく巻取紙をも切断して了うことになるという課題を有
していた。In the above-mentioned prior art, the outer paper cutting guide member is resiliently suspended vertically in the outer paper opening head, so that it can swing up and down. Even if it can be moved, it is not movably mounted in the up and down direction, so if the web is placed sideways with a slight inclination upward in the axial direction,
Since the opening head moves horizontally in the web axis direction, the elastically suspended cutting guide member moves forward while being displaced upward following the upward inclination, but the cutting cutter is elastically suspended vertically with respect to the opening head. There is a problem that the cutting cutter advances in the horizontal direction because there is no cutting paper, and as a result, the cutting cutter finishes cutting not only the exterior paper but also the web paper as the cutting cutter advances.

の技術手段に比し差異はない。[0004] However, when the paper roll is placed sideways with a slight downward inclination, the paper cutter is lifted by the incision guide member. What can be done is not different from the above-mentioned conventional technical means.

軸方向に走行する移動体に弾性体を介して巻取紙軸線方

ある。According to the present invention, in order to solve the above-mentioned problems of the prior art, the opening head is mounted on a moving body which travels in the axial direction above the paper web with an elastic body in the axial direction of the web paper. The opening head is tilted in accordance with the inclination of the web axis so that the opening head can be tilted in the direction.

り込みをすることはない。When the paper roll is placed in the forward-upward position, the cutting guide member receives an upward external force as it moves forward to lift the opening head, and the opening head is an elastic body elastically suspended between the moving body and the opening head. The cutting cutter does not make a deep cut to cut the web up to the web because it is compressed and moves forward following the upward slope of the web.

1 is a front view of a main part, and FIG. 2 is a side view of FIG. A moving body 2 running in the axial direction of the paper web above the exterior paper 1 enclosing the horizontally placed web paper includes a top detector 3 of the external paper 1, a hanging rod 5 of an external paper cutout suction pad 4, and an opening head 6. And are attached. The opening head 6 is elastically suspended on the moving body 2 by a bolt 8 having a coil spring 7 interposed therebetween.
Therefore, the opening head 6 compresses the coil spring 7 with respect to the moving body 2 and can be tilted upward with respect to the web axis direction, but is not displaced downward.

る。A base of a cutter rod is fixedly mounted on a moving piece that moves back and forth by the cylinder device 9 on the opening head 6, and an outer paper cutting cutter 10 is attached to the tip of the cutter rod so as to be rotatable. An exterior paper incision guide member 11 having a shoe is elastically suspended by a bolt 13 with a coil spring 12 interposed therebetween so that only the downward displacement of the unsealing head 6 can be freely performed.
4 guides the guide groove 15 formed in the opening head to move forward and backward to an upper inoperative position and a lower operating position (shown).

に走行させることにより外装紙１は切断開封される。Then, the incision cutter 10 is placed at the retreating position, the incision end of the exterior paper 1 is suctioned and floated by the suction pad 4, and the cylinder device 9 is extended to move the incision cutter 10 forward and rotationally drive to float. Cut and open the end of the exterior paper
Next, the inclining guide member 1 is operated by extending the cylinder device 14.
1 is advanced, inserted into the gap formed between the raised back surface of the outer paper and the front surface of the web, and the outer body 1 is cut and opened by moving the moving body 2 in the web axis direction.

して巻取紙まで傷付ける深切り込みは回避される。At this time, there is a case where the web paper placed horizontally is slightly inclined upward in the axial direction due to the influence of the floor surface, but in such a case, the moving body 2 moves forward. Since an upward external force acts on the incision guide member 11, the opening head 6 compresses the coil spring 7 between the moving body 2 and inclines according to the forward ascending inclination of the paper roll. Moves parallel to the ridge line of the exterior paper 1, thereby avoiding a deep cut that cuts only the exterior paper 1 and damages the web.

る。[Effects of the Invention] In the present invention, the opening head with the cutting cutter is elastically suspended on the moving body so that it can only be tilted upward with respect to the axial direction of the web, so that the web is inclined forward and upward on the floor in the axial direction. Even if it is placed horizontally, the guide of the incision guide member which is urged downward to the ridgeline of the paper roll allows the opening head to advance forward by tilting in accordance with the front upward inclination of the paper roll,
The incision cutter moves in parallel with the wrapping paper ridge line, and there is no danger of damaging the surface of the web by the incision cutter by cutting and opening only the outer paper, and a stable and reliable outer paper opening operation can be performed. Its practical effect is significant.
