。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is applicable to synthetic resin films such as mulching sheets for agriculture or gardening, house deaeration sheets, and packaging sheets for packaging materials that require air permeability. Conventional technology] Conventional film punching machines that make holes in synthetic resin films are press-type film punching machines that have an upper die with a cutting die or rotating blade and a lower die that serves as a receiver and a pendulum-shaped machine. There is an opportunity to use a pendulum-type film aperture that moves the cutter blade to make the hole.
前者のプレス式フィルム孔開は機は、型による孔開けで
あることから、正確なピッチで、歪みのない正確な孔が

置が長くなり、フィルムパス(通過)機構も煩雑になる
。The former press-type film punching machine uses a mold to punch holes, so holes can be punched at precise pitches and without distortion. However, since the operation is intermittent due to the mold, it is difficult to speed up, the efficiency is low, and vibrations and noise are likely to occur. Also, there is a gap between the film manufacturing equipment and the hole punching machine.
A dancer roller is required to stand by during hole punching, which increases the length of the device and complicates the film passing mechanism.
更に能率化を図るために刃物を多列化することになるの
で、機械が大型化し、コスト高となる。Furthermore, in order to improve efficiency, the blades are arranged in multiple rows, which increases the size of the machine and increases the cost.

なり、安価なものとなる。On the other hand, the latter type of pendulum-type film perforation is efficient because it uses a cutter blade that moves in a pendulum-like manner. Furthermore, since the number of rows of cutter (rotary blades) in the film transport direction is reduced, the mechanism becomes simpler, and the machine becomes more compact and inexpensive.
しかしフィルム搬送速度とカッタ揺動の周速とを同調さ

とができず、従って能率が上げられない、また揺動する
カッタを搬送フィルム面に垂直に当接させることは困難
であることから、孔が変形し易く正確な孔が開けにくい
。However, it is difficult to synchronize the film transport speed and the circumferential speed of the cutter swing, making it difficult to make holes at an accurate pitch. In addition, the tuning range in which any set pitch can be set is narrow, and the tuning limit speed (approximately 20 m/lll1n) is low. Also, it is difficult to bring the swinging cutter into contact with the surface of the conveyed film perpendicularly, so the holes are easily deformed and it is difficult to make accurate holes.

持機構を設けてなるものである。The configuration of the present invention for achieving the above object is such that the drive of the drive motor is transmitted via a continuously variable transmission mechanism to a support rotation on a film conveyance path on which a pinch roller is provided which is rotated by the drive of the drive motor.

That is, the hole opening is arranged by rotating the radius R of the circular motion of the mechanism part (the rotary blade C revolves) so that the mechanism part is in rolling contact with the conveying film 2 on the film conveying path A. The rotary blade C is at the bottom position and the conveying film 2
The eccentric mechanism is adjusted and determined so that holes are made at a predetermined pitch P by sequentially coming into contact with the holes. Note that the eccentric operation handle 15 gets in the way during circular motion, so it is removed after adjustment.

せる。Next, the transport speed of the transport film 2 transported on the film transport path A is determined. The pinch roller 5 provided on the film transport path A is driven by a drive motor M consisting of a variable speed motor.
Since the rotation of the transport film 2 is transmitted through the chain 6, the transport speed of the transport film 2 is determined by the eccentric speed of the drive motor M. Subsequently, the drive motor M and the hole opening change the peripheral speed of the circular motion (revolution) of the mechanism by operating the speed change operation handle 9 of the continuously variable transmission H interposed between the mechanism. The conveying speed of the conveying film 2 and this rotating circumferential speed are synchronized.

It will be done. In the hole punching mechanism, rotary blades C are arranged in the film width direction with an arbitrary width α, and are arranged in two rows with a constant width (1/2P) in the film transport direction. As a result, the conveying film 2 has a constant width α in the film width direction.
, and holes are opened at a constant pitch P along the conveyance direction. If the rotary blades C are arranged in two rows in the transport direction as shown in the figure, holes can be opened at 1/2P intervals, and if a large number of rotary blades C are arranged in this way in the transport direction, the holes can be opened more efficiently.

ト低減にもなる。As described above, the present invention provides a supporting rotating shaft on the film transport path to which the drive of the drive motor is transmitted via a continuously variable transmission mechanism, and a plurality of rotating blades are arranged on the supporting rotating shaft via an eccentric mechanism. Since a hole drill is equipped with a mechanism, the radius of the circular motion of the mechanism can be changed by adjusting the eccentric mechanism, and the radius of the circular motion of the mechanism can be changed by adjusting the eccentric mechanism. The pitch can be matched to the pitch of the holes to be formed in the transport film in the film transport direction. In addition, by adjusting the continuously variable transmission mechanism, the circumferential speed of rotation of the circular motion of the mechanical part is changed, and the circumferential speed of rotation of the mechanical part and the conveying speed of the conveying film are synchronized to form holes in the conveying film at an accurate predetermined position. The holes are opened continuously at a pitch, so the holes can be opened efficiently and the speed can be increased. The film transport speed is determined by the rotation speed of the drive motor, and the peripheral speed of the same movement of the perforation mechanism is changed by a continuously variable transmission, so the machine operating speed can be freely selected to suit the needs of the film perforation. Therefore, it is possible to select an appropriate operating speed depending on the arrangement and number of holes formed, and smooth operation without vibration or noise is possible at both high and low speeds. . In addition, since the hole punching mechanism is equipped with a vertical holding mechanism, it is possible to punch holes by bringing the rotary blade that rotates on its own axis into contact perpendicularly to the surface of the conveyed film on the film conveyance path. Therefore, it is possible to form an accurate hole without distortion, and therefore, the hole drilling process can be made more precisely. Furthermore, since we adopted a method that continuously drills holes using rotating blades that revolve and rotate on their own axis, fewer rotating blades are required, and the mechanism is relatively simple, resulting in the overall simplicity and downsizing of the machine. This will of course lead to cost reduction.
