本発明は、紙、フィルムなどの幅広のシート材料をその
長手方向に切断する装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for cutting wide sheet materials such as paper, films, etc. in their longitudinal direction.
円板刃と丸刃により、紙、フィルムなどのシート材料を
長手方向に切断する装置は、切断時には、適切な圧接力
で円板刃を丸刃に圧接して切断が可能な状態とし、切断

る必要があり、圧接のたび毎に圧接力が変化してはなら
ない。A device that uses a disc blade and a round blade to cut paper, film, and other sheet materials in the longitudinal direction is capable of cutting by pressing the disc blade against the round blade with an appropriate pressure force when cutting. When not in use, it is necessary to separate the round blade and disc blade and put them in a standby state, and the pressure contact force must not change each time the pressure contact is made.
圧接力が弱くなった場合、切れ味が悪くなり切り口の平
滑度合が低下し、圧接力が強くなりすぎると、丸刃、円
板刃とも刃先が異常摩耗を生じて早期に寿命となってし
まう。If the pressing force becomes weak, the cutting edge becomes dull and the smoothness of the cut end decreases, and if the pressing force becomes too strong, the cutting edge of both round blades and disc blades will suffer abnormal wear, resulting in premature end of their life.

ずかなばらつきにより圧接力が大きく変化するため、調
整が非常に難しい。In other words, since the solenoid plunger is attached directly to the arm member that supports the disc blade, when the disc blade is pressed against the disc blade by the suction force of the solenoid, the suction force acts directly on the disc blade, so the circular Adjustment is extremely difficult because the contact force changes greatly due to slight variations in the axial positional relationship between the plate blade and the round blade.

内に納めるためには、円板刃と丸刃との圧接方向の位置
関係を非常に精密に調整する必要があるので、切断装置
の組立時の作業が煩雑で、かつ圧接力を規定値に納めに
くいという問題点があった。As mentioned above, in order to keep the pressure contact force within the specified value range with conventional equipment, it is necessary to adjust the positional relationship between the disc blade and the round blade in the pressure direction very precisely. There were problems in that the assembly work was complicated and it was difficult to keep the pressure contact force within a specified value.
また、圧接力のばらつきが発生し易く、このため切れ味
にもばらつきが発生し、シートの切り口の平滑度にもば
らつきを生じてしまうという問題点もあった。Further, there is a problem in that the pressing force tends to vary, which causes variations in the sharpness, and also causes variations in the smoothness of the cut end of the sheet.

徴とするシート材切断装置である。The present invention includes a rotatably driven round blade, a rotatably supported disk blade, and a movement device for the disk blade that presses and separates the disk blade and the round blade from each other, The sheet material cutting device is characterized in that the stroke of the moving device is transmitted to the disc blade via an elastic body, and the disc blade is pressed against the round blade to cut the sheet material. .

簡便である。That is, the present invention provides an elastic body between the solenoid plunger, which is the drive source of the disc blade, and the arm member that supports the disc blade, and directly converts the suction force when the solenoid plunger is sucked into pressure contact force. First, by transmitting the suction force to the disc blade through an elastic body, the pressure contact force is kept within the specified value without having to make fine adjustments to the positions of the disc blade and the round blade. This is a cutting device for sheet materials. Any elastic body may be used as long as it can transmit the above-mentioned suction force to the disc blade.
Spring, rubber, etc. are desirable, but using a spring is the simplest.
次に実施例と図面に基づいて本発明をさらに詳細に説明
する。Next, the present invention will be explained in more detail based on examples and drawings.
第１図は、本発明のシート材切断装置の一実施例を示す
正面図と、側面図であり、第２ｍは円板刃が待機してい
る状態を示す正面図である。FIG. 1 is a front view and a side view showing one embodiment of the sheet material cutting device of the present invention, and FIG. 2m is a front view showing a state in which the disc blade is on standby.

支軸４は、腕部材５の先端部に固定されており、この腕
部材５は回転支軸６を中心として回転が可能である。In FIG. 1, a round blade 1 is fixed to a drive shaft 2 that rotates in the direction of the arrow. A disc blade 3 having an acute-angled cutting edge is rotatably supported on a disc blade support shaft 4. This disc blade support shaft 4 is fixed to the tip of an arm member 5, and this arm member 5 is rotatable around a rotation support shaft 6.

ド１１によって作動する。The plunger 8 is actuated by a solenoid 11 via a compression spring 10 and a cylinder 12 fixed to a solenoid plunger 13.

断される。When the bush solenoid 11 is energized, the solenoid plunger 13 moves in the direction of the round blade 1, and the slidable plunger 8 inserted into the cylinder 12 fixed to the solenoid plunger 13 is pushed by the compression coil spring 9. Then, the arm member 5 is rotated, and the disc blade 3 is brought into pressure contact with the round blade 1 to be in a cutting state. Due to the frictional force generated by this pressing force, the disc blade 3, which does not have a driving source, rotates in conjunction with the round blade 1, and the sheet material is cut at the position where the disc blade 3 and the round blade 1 come into contact.

先端が丸刃１から速やかに離反する。When returning the cutting device to the standby state, if the bushing solenoid 11 is de-energized, the arm member 5 is pulled by the return spring 10 and rotates counterclockwise on the top of the figure, so that the tip of the disc blade 3 is rounded. It quickly separates from the blade 1.

め、切断の作業性が良くなる。さらに、圧接力が規定値
内で安定するのでシート材の切断の安定性も向上する。As described above, when the cutting device of the present invention presses the disc blade 3 against the round blade 1, the spring generates a pressing force, so that the pressing force can be adjusted to an appropriate value by setting the elastic force of the spring. Therefore, it is no longer necessary to adjust the pressing force by finely adjusting the positions of the disc blade 3 and the round blade 1 as in the conventional case, and thus the cutting workability is improved. Furthermore, since the pressure contact force is stabilized within a specified value, the stability of cutting the sheet material is also improved.

きる。As explained above, the present invention has a mechanism in which when the arm member to which the shaft portion of the disc blade is fixed approaches the round blade, the disc blade comes into pressure contact with the round blade using an elastic body. It is characterized by
The pressure force can be easily adjusted using the spring setting value, and variations in the pressure force due to the positional relationship between the disc blade and the round blade can be minimized, eliminating the need for fine adjustment of the pressure force and stabilizing the sheet material. It is possible to provide a sheet material cutting device that can cut the sheet material.
