2. Description of the Related Art As a conventional means for unsealing and cutting an outer paper of a roll of paper, as disclosed in Japanese Patent Laid-Open No. 2-4627, a folded-back ear portion is left on an edge of the outer-paper side and the folded-back ear portion is left. The outer paper is opened by forming the space by separating the outer paper and the roll-up paper by rolling up the upper part and pushing the opening shoe into the space to move the outer paper. As a preparatory work for this, while leaving the folded back ears, the start edge of the exterior paper,
It was necessary to attach a marking for the thickened area of the exterior paper to the end superposition area.

That is, as shown in FIG. 6, a mark S for indicating the winding end area of the paper roll is attached to the end face of the paper roll, and the folded-back ear portion is provided on the side edge of the exterior paper E at a position other than the mark S. E ″ is left, and the ear portion E ″ is grasped by the opening / closing gripper and erected and lifted to form a space between the back surface of the exterior paper and the front surface of the paper roll, and the opening shoe is pushed into the space and moved. Only the exterior paper is cut and opened, and only the exterior paper can be opened and cut without damaging the roll paper.

[0004]

According to the above-mentioned conventional technique, in order to leave the folded back ear portion E ", it is necessary to manually cut off the folded back portion other than the folded back ear portion E". Even if the display mark S is attached to the end face, the position to be attached is visually determined and manually attached. Therefore, even if the opening and cutting work of the exterior paper is mechanically performed, the mechanical work is performed. In the stage before entering, there was a problem that preparation work that depended on manual work had to be performed.

[0005]

Therefore, in the present invention, it is not necessary to leave the folded-back ears, and it is not necessary to attach the thickened region display mark, and there is no preparatory work in the previous stage which depends on manual work. In order to make it possible to open and cut the exterior paper only by mechanical means, a pair of suction pads in which the peripheral surface near the side edges of the exterior paper with no fold-back portion at the exterior paper side edge are spaced apart in the circumferential direction. By suction to form a space between the front surface of the paper roll and the back surface of the exterior paper, press the exterior paper cutting guide member into the space to release the suction of the suction pad, and press the cut guide member to float. The cutter, which has the outer peripheral surface of the outer paper positioned between the pair of suction pads, is moved in the axial direction of the paper roll to open and cut the outer paper.

[0006]

With a pair of suction pads, a part of the exterior paper on the side surface of the side edge of the roll paper wrapped with the package paper and laid horizontally is floated by a pair of suction pads, and between the back surface of the roll paper and the front surface of the roll paper. The exterior paper cutting guide member is pushed into the gap to partially float and separate the exterior paper and the roll paper, and the separated and floated exterior paper portion is opened and cut by moving the cutter in the axial direction of the roll paper and the suction pad The negative suction pressure is released, and the unsealing head having the outer paper cutting guide member and the cutter attached thereto is moved in the axial direction of the web by the movement of the moving body to unseal the outer paper.

[0007]

1 and 2 are a front view and a side view, respectively, of the present invention. Above a pair of rolls R, R which are laid side by side and wrapped with an exterior paper 1, a roll of paper 2 is provided. A gate-shaped frame F that straddles the carriage is disposed, and a moving body 3 that reciprocates in the axial direction of the web 2 is provided on the gate-shaped frame F, and an elevating rod 4 is supported on the moving body 3 so as to be vertically movable. And is moved up and down by the cylinder device 5 on the moving body 3.

An opening head 6 is attached to the lower end of the elevating rod 4, and an exterior paper cutting guide member 7 is attached to the opening head 6.
An outer paper cutting cutter 8 and a pair of suction pads 9A and 9B are provided, and the outer paper cutting guide member 7 moves along a guide groove formed in the opening head 6 by the extension operation of the cylinder device 10 to be described later. It is pushed into the separated space formed between the back surface of the paper 1 and the front surface of the paper roll 2, facilitating the cutting of only the outer paper by the cutter 8, and the outer paper cutting cutter 8 is moved by the extension operation of the cylinder device 11. 1 moves from the position shown by the solid line in FIG. 1 to the position shown by the chain line along the guide groove formed in the unsealing head 6, and is rotated by the drive of the motor 12 via the belt.

Furthermore, a pair of suction pads 9A, 9B
Are separated from each other in the circumferential direction of the paper roll 2 and are provided with respective support rods 9'and 9 ".
Is suspended from the lower end of the cylinder, and the supporting rods 9'and 9 "are cylinder devices.
An elongate arc-shaped hole 16 which is opened in a diverging manner in an elevating plate 15 which ascends and descends along a guide rail 14 vertically installed on the unsealing head 6 by
A and 16B (see FIG. 4) are inserted into the support rods 9'and 9 ".
The projecting locking plates 17A and 17B are locked to the lifting plate 15 when the lifting plate 15 is lifted, and the supporting rods 9'and 9 "are moved together with the lifting plates 15 to pull up the suction pads 9A and 9B. .

Further, a pair of links 18 pivotally supported at a central portion by a pivot 17 standing on the lifting plate 15 is provided at a forked end of a piston rod of a cylinder device 16 provided on the lifting plate 15.
One ends of A and 18B are connected to each other through a long hole, and the other ends of the links loosely insert the support rods 9'and 9 ".

Therefore, when the cylinder device 16 is extended, the suction pads 9A and 9B are attracted to the exterior paper 1 and only the upper portions of the support rods 9'and 9 "are arc-shaped so as to spread toward the position shown in FIG. Since they move along the long holes 16A and 16B, the respective support rods 9'and 9 "tilt and the suction pad 9 moves.
As shown in FIG. 3, A and 9B are tilted in the direction in which the cutout portion 1'of the exterior paper 1 is expanded.

Therefore, first, the movable body 3 is moved to the vicinity of the edge of the paper 2 placed horizontally, and then the cylinder device 5 is extended and the upper surface detector 19 attached to the unsealing head 6 is attached to the exterior paper 1. The opening head 6 is lowered until it comes in contact with the peripheral surface of the
Is rotated from the horizontal position to the vertical position by the operation of the rotary actuator 21, and the movable body 3 is moved in the axial direction of the paper roll until the end face detector 20 is connected to the end face of the paper roll 2 to move the moving head 3 vertically and horizontally. Align the direction.

Next, the cylinder device 13 is extended to lower the support rods 9 ', 9 "until the suction pads 9A, 9B land on the peripheral surface of the outer paper 1 to start suction. A well-known vacuum sensor is used to confirm whether or not the pads 9A and 9B are adsorbed on the exterior paper.

When the cylinder device 13 is contracted to suck up the exterior paper 1 after the suction is confirmed, only the exterior paper 1 is pulled up and floated, and the back surface of the exterior paper and the front surface of the paper roll are separated from each other to form a gap. To be done.

Next, the cylinder device 11 is extended to move a cutter device having a cutter driving motor 12, a rotary cutter 8 and the like along a guide groove (not shown) provided in the opening head 6, The cutter 8 cuts only the exterior paper between the pair of suction pads that are suction-floating, and
By the extension operation of the cylinder device 16 shown in FIG. 4, the suction pads 9A and 9B are tilted in the direction of opening the cut opening of the cut exterior paper portion, so that the exterior paper cutting guide member 7 can be easily pushed. If the cutter is a toothless cutter that does not have saw teeth, the generation of chips can be prevented.

The cutting guide member 7 is a cylinder device.
By the extension operation of 10, the cutting guide member 7 moves along the guide groove provided in the unsealing head 6, pushes the cutting guide member 7 into the cutting opening of the exterior paper portion in the floating state, and sucks the pad 9.
The suction negative pressure of A and 9B is released, and the opening edge of the cut and opened outer paper 1 is guided between the lower guide member 7A and the upper guide member 7B of the guide member to guide the guide guiding confirmation sensor 22. The rotary actuator 21 is actuated by the signal to rotate the end face detector 20 to a horizontal position and retract it from the end face position, thereby allowing the opening head 6 to move forward. A spring 23 is provided to allow the cutting guide member 7 to swing in the vertical direction when the cutting and unsealing are performed. And the lower guide member 7
By advancing the tip of A ahead of the cutting position of the cutter, it is possible to reliably cut only the exterior paper.

Therefore, the elevating rod 4 having the unsealing head 6 moves the peripheral surface portion of the paper roll 2 placed laterally by the moving body 3 in the axial direction of the paper roll so that the exterior paper 1 is moved.
Is opened and cut.

When the opening and cutting of the exterior paper 1 is completed, the rotation of the cutter is stopped, the exterior paper cutting guide member 7, the cutter and the suction pad are returned to their original positions by the reduction operation of the respective cylinder devices, and the moving body is retracted. It moves and waits for the arrival of the paper wrapper wrapped in the subsequent exterior paper.

[0019]

As described above, according to the present invention, the suction pad separates the exterior paper from the surface of the paper roll so that a space is formed between the back surface of the paper exterior and the surface of the paper roll, and the incision guide member is pushed into the space to separate the space. Since only the outer paper part that is being used is unsealed and cut by the cutter in the axial direction of the paper roll, the cutter can cut only the outer paper without damaging the surface of the paper roll. Therefore, it is possible to easily open and cut the thickened part where the start end and the end of the outer paper and the web are overlapped with the cutter. There is no need to do this, and since the opening and cutting can be performed from any peripheral surface of the exterior paper, the opening work can be performed easily and quickly.Furthermore, the suction pad can be used to fold the exterior paper on the end face of the paper roll. Even if the outer paper does not remain, it is possible to easily form a gap between the back surface of the outer paper and the front surface of the paper roll to press the cutting guide member of the outer paper, so the preparatory work for opening and cutting the outer paper is unnecessary. The effect is remarkable, such as labor saving.
