Abstract

PURPOSE:To cut a continuous leaf sheet even with a small down stroke of a cutter, which cuts the sheet at its perforation, by equipping the cutter with a sawteeth form cutting edge. CONSTITUTION:When a sensor senses that the perforation 7 of a continuous leaf sheet has come to the foremost of a receptacle table 6, rotation of rollers R, R' is once stopped. The rollers R, R' rotate so that a tension is applied in the direction perpendicular to the perforation 7 with the perforation 7 positioned in the center, and are stopped. Then a solenoid 4 is energized to sink a cutter 1, which cuts the sheet 5 at the perforation 7. Because the cutter 1 cuts the sheet with three saw-teeth cutting edges 1a arranged across the width, so that the cutting length shared by one cutting edge 1a is one third of the sheet S width, which reduced the burden on one cutting edge compared with a conventional arrangement using only one cutting edge. Further, the cutting can be done effectively because the sheet is pulled to the left and right centering the perforation 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous-recording medium cutting device, and more particularly to a miniaturized device having a small cutter stroke.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3, a cutting blade of this type of continuous form medium cutting device has a length substantially equal to the width of a continuous form medium (hereinafter referred to as a sheet). It is composed of the inclined blade 10. And this inclined blade 1
The cutting of the sheet S by 0 is performed by lowering the inclined blade 10 toward the perforations provided on the sheet S, and the descending stroke of the inclined blade 10 at this time (sometimes referred to as a stroke). L is the length by which the inclined blade 10 cuts the entire width of the sheet S.

[0003]

However, in the above-mentioned conventional apparatus, since the cutting blade of the cutter is one inclined blade, in order to completely cut the sheet, the inclined blade is provided over the entire width of the sheet. Had to be brought into contact with each other, resulting in a long stroke of the cutter. Further, when the stroke of the cutter becomes long, the solenoid for driving the cutter becomes large and the cutting time becomes long.

Therefore, the present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to provide a sheet cutting apparatus with a small descending stroke of the cutter.

[0005]

In order to achieve the above-mentioned object, the apparatus of the present invention lowers the cutter from above toward the perforations provided in the direction orthogonal to the longitudinal direction of the sheet and lowers the sheet. In the sheet cutting device for cutting from the perforation, the cutter has a saw-tooth cutting blade. Further, the continuous form medium is characterized in that, when the cutter is brought into contact with the cutter, tension is applied in the direction orthogonal to the direction of the perforation around the perforation to be cut.

[0006]

In the above structure, when the saw-toothed cutting blade is lowered from above the perforation of the sheet, the sheet is cut from the perforation. At the time of this cutting, tension is applied to the sheet in the direction perpendicular to the perforations centering on the perforations, so that the sheet is instantly cut from the perforations when the cutting blade is brought into contact with the perforations.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1A is a schematic configuration diagram of the apparatus of one embodiment, and FIG. 1B is a front view seen from the direction of arrow A in FIG. The length of the cutter 1 is almost the same as the width of the sheet S, and three saw blade-shaped cutting blades 1a, 1a, 1a are formed on the lower side thereof. The cutter 1 is fixed to the tip of the arm 2, and the other end of the arm 2 (the end on the side opposite to the side where the cutter 1 is provided) is in a direction orthogonal to the longitudinal direction of the sheet S. It is fixed to the shaft 3 provided. Both ends of the shaft 3 are rotatably supported by the frame F and are reciprocally rotated by a predetermined angle by a solenoid 4. That is, the shaft 3 is connected to the rod 4 ′ of the solenoid 4 via the auxiliary rod 5, and the solenoid 4 turns ON / O.
When the rod 4'is moved in the vertical direction (see the arrow B) by the FF, the shaft 3 can be rotated along with the movement. Therefore, when the shaft 3 rotates, the cutter 1 provided at the tip of the arm 2 can move up and down as indicated by the arrow B.

In the figure, reference numeral 6 denotes a pedestal provided so as to face the lower side of the cutter 1, and contacts the end surface of the pedestal 6 when the cutter 1 descends, and the cutter 1 and the pedestal 6 are joined together. It is provided so as not to collide. Also, R,
R'is a pair of upper and lower rollers provided on both sides of the pedestal 6, and is configured to be rotationally driven by a motor (not shown). In addition, the motor of the roller R is a reversible motor, and is configured so that the sandwiched sheet can be moved also in the arrow E direction.

Next, the operation of the apparatus of this embodiment will be described. As shown in FIG. 2, the sheet S is provided with perforations 7, 7 ... At predetermined intervals in the longitudinal direction.
When the seat S is a ticket, items such as the boarding date are printed in advance between the perforations 7 and 7 by a printing mechanism (not shown), and when the seat S is a tag used when boarding an airplane, Items such as airline name and flight number are printed in advance between the perforations 7 and 7. Note that this printing may be performed after the cutting process described later.

The sheet S is nipped by rollers R and R'and moved on the pedestal 6 in the direction of arrow C. When the sensor (not shown) detects that the perforation 7 is located at the tip of the pedestal 6 (the end facing the cutter 1), the rotation of the rollers R and R'is temporarily stopped. And roller R,
R'rotates around the perforated line 7 to be cut so as to apply tension in a direction orthogonal to the direction of the perforated line 7 (see arrows D and E in FIG. 1) and is stopped. Next, the solenoid 4 is turned on, the cutter 1 descends, and the sheet S
Is cut from the perforation 7. This cutting is instantaneously performed because tension is applied in the left-right direction around the perforations 7. The cut sheet S is discharged by the roller R ′, and the remaining sheet S is moved by the roller R until the next perforation 7 is located at the tip of the pedestal 6.

The lowering stroke L for cutting the perforations 7 by lowering the cutter 1 is 1 / th that of the conventional position shown in FIG.
It becomes 3. Because the cutter 1 cuts the width of the sheet S with the three sawtooth cutting blades 1a, the cutting length that one cutting blade 1a has to cut is 1/3 of the width of the sheet S. This is because it is 1/3 as long as when cutting with one blade as in the conventional case. Further, since it is pulled in the left-right direction around the perforation 7 to be cut, the cutting is effectively performed.

In the apparatus of this embodiment, since the stroke L of the cutter 1 is small and it is in time, not only the solenoid 4 can be downsized, but also the up and down range of the arm 2 can be reduced, so that the entire apparatus can be downsized. is there.

In the above embodiment, the number of sawtooth cutting blades 1a is three, but the number may be two or four or more. Further, the sawtooth shape may be an inverted triangular shape as shown in FIGS. 4 (a) and 4 (b).

[0014]

In the apparatus of the present invention, the cutting blade of the cutter has a sawtooth shape, so that the sheet can be cut even if the descending stroke of the cutter is small, and the solenoid for driving the cutter is downsized. can do. Further, when tension is applied to the sheet around the perforations to be cut, the cutting is effectively performed.
