Description of the Related Art A paper tube used for a core of toilet paper, a tubular container made of paper, and the like is formed by spirally winding a paper tape into a plurality of layers. A paper tape, which is a material of a paper tube, is formed by cutting a wide band-shaped paper sheet into a tape shape by a cutting machine.

取り軸(11)に巻き取る。FIGS. 1 to 3 show a cutting machine embodying the present invention. Since the basic structure is the same as that of a conventional cutting machine, the conventional cutting machine will be described with reference to these drawings. The paper sheet S is pulled out from the raw coil (9) wound with the wide band-shaped paper sheet S, and is wound around a winding shaft (11) through a guide roller row (3) on a base (1).

り軸(11)上のシートを押えている。A tool mount 4 is supported on the base 1 at the downstream end of the roller row 3 so as to be able to undulate, and an upper blade 43 provided on the tool mount 4 is provided. The paper sheet S immediately before winding is bitten between the lower blades (44), and the sheet is continuously cut in the sheet moving direction. A press roller (45) is provided at a free end of the blade mount (4), and the press roller (45) always presses the sheet on the winding shaft (11).

(4) Air cylinder that acts in the direction of lifting the free end
(8) is linked. The air cylinder (8) plays a role in reducing the load on the sheet on the winding shaft (11) due to the weight of the blade mount (4).

テープへの荷重は小さくなる。As the amount of paper tape wound around the take-up shaft (11) increases, the pressing roller (45) of the blade mounting base (4) in contact with the paper tape becomes increasingly wound by the take-up shaft.
Moving away from (11), the free end of the tool mount (4) rises. As the free end of the blade mount (4) rises, that is, as the undulation angle α of the blade mount (4) increases, the weight of the blade mount (4) causes the paper tape on the winding shaft (11) to move to the paper tape. The load decreases.

てしまう。Therefore, if the air pressure supplied to the air cylinder (8) connected to the blade mount (4) is constant,
If the undulation angle α of the blade mount 4 becomes large, the force of the pressing roller 45 for pressing the paper tape on the winding shaft 11 becomes weak, or the blade mount 4 is separated from the paper tape. .

く巻くことはできない。In order to wind the paper tape tightly and beautifully around the winding shaft (11), it is necessary to hold the paper tape while pressing it with a constant force, and the pressing force of the pressing roller (45) against the paper tape is too small or When the roller (45) separates from the paper tape, the paper tape meanders and winds around the winding shaft (11), and cannot be beautifully wound.

る。Conventionally, an operator visually observes the undulating state of the blade mounting table (4), and manually operates a pressure reducing valve connected to the air cylinder (8) to reduce the pressure inside the air cylinder (8). The pressing force against the paper tape on the take-up shaft (11) is adjusted.
In the above case, the operation of the pressure reducing valve depends on the operator's feeling, and the pressure reduction adjustment is stepwise, and the pressing force on the paper tape on the winding shaft (11) also changes stepwise. ,
Paper tape cannot be wound stably. In addition, the worker is cut off by the cutting machine, which is a bottleneck for labor saving.

(4) By providing a pressure reducing valve automatic operating means that automatically operates according to the undulation angle, even if the winding diameter of the paper tape becomes large, the paper tape is pressed with a substantially constant force to solve the above problem. It is also about.

Pressing roller provided at the free end that is rolled up and undulated
(45) is a paper for cutting the paper sheet S just before winding into a tape shape in the winding direction by the cutting blades (43) and (44) on the blade mounting base (4) which is placed on the winding shaft (11). In the sheet cutting machine, the cutter mounting table (4) reduces the load of pressing the paper tape on the winding shaft (11) by its own weight.
(4) The blade mount so that the free end acts in the lifting direction
For the air cylinder (8) connected to (4), a pressure reducing valve (6) is provided in the pipeline connected to the air cylinder (8), and the blade mounting base (4) and the pressure reducing valve (6) are mounted on the blade. The free end of the stand (4) is linked via automatic pressure reducing valve operating means (5) for increasing the throttle amount of the pressure reducing valve as it rises.

リンダ(８)内を徐々に減圧する。[Operation and Effect] As the winding diameter of the paper tape on the winding shaft (11) increases, the undulation angle α of the blade mounting base (4) gradually increases. In response to the change of the undulation angle α of the blade mounting base (4), the pressure reducing valve automatic operating means (5) works to automatically operate the pressure reducing valve (6) connected to the air cylinder (8), and to operate the air cylinder (8). The pressure inside is gradually reduced.

ープを安定して緊く、美しく巻くことができる。As a result, as the undulation angle α of the blade mount (4) increases, that is, as the load on the paper tape on the winding shaft (11) due to the weight of the blade mount (4) decreases, The urging force of the cylinder that urges the blade mount (4) in the upright direction is weakened. Therefore, the pressing pressure of the paper tape on the take-up shaft (11) by the pressing roller (45) on the blade mounting table (4) can be made substantially constant even if the diameter of the paper tape changes, and the sheet While cutting continuously, this paper tape can be stably wound tightly and beautifully.

る。The pressing roller (45) on the blade mount (4) is mounted on the winding shaft (11). When the winding shaft (11) is forcibly rotated, the sheet is pulled toward the winding shaft (11), and the sheet is cut into a tape shape by the upper blade (43) and the lower blade (44). As the diameter of the paper tape on the take-up shaft (11) increases, the undulation angle α of the tool mount (4) gradually increases. The support shaft (40) for supporting the base end of the arm (46) of the blade mount (4)
It rotates according to the change of the undulation angle α of the blade mounting base (4).

い。The rotation of the support shaft (40) causes the drive gear (51) of the pressure reducing valve automatic operating means (5) to rotate integrally with the support shaft (40) to rotate the driven gear (52). The needle (61) of the pressure reducing valve (6) fixed to the shaft of the driven gear (52) rotates to reduce the pressure in the air cylinder (8) that urges the blade mount (4) upward. The driven gear (52) to which the needle (61) is fixed is supported slidably in the axial direction, and does not hinder the movement of the needle (61).

ープを安定して緊く、美しく巻くことができる。Thus, as the undulation angle α of the blade mount 4 increases, that is, as the load on the paper tape on the winding shaft 11 due to the weight of the blade mount 4 decreases, The urging force of the cylinder that urges the blade mount (4) in the upright direction is weakened. Accordingly, the pressing force of the pressing roller (45) on the blade mounting table (4) to the paper tape on the winding shaft (11) can be made substantially constant even when the diameter of the paper tape changes, and While cutting continuously, this paper tape can be stably wound tightly and beautifully.
