本考案はフイルム延伸装置に於けるフイルム搬
送用の把持装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gripping device for transporting a film in a film stretching device.
一般に熱可塑性合成樹脂フイルムを延伸処理す
る場合は、口金より吐出された未延伸フイルムを
ローラ式の延伸装置等に供給し、所定の温度のも
とで所定の方向，厚さに延伸している。 Generally, when stretching a thermoplastic synthetic resin film, the unstretched film discharged from a die is fed to a roller-type stretching device, etc., and stretched at a predetermined temperature in a predetermined direction and thickness. .
前記延伸装置の処理部は高温域であると共に多

ーラに巻付き破れたり、ローラへの巻付巻太りで
延伸装置を破損させる等の事故が度々発生する欠
点があつた。 The processing section of the stretching device is in a high temperature range and has a large number of rollers, multiple sets of nip rollers, etc., so it is impossible to manually pass the unstretched film between the rolls. Alternatively, a pair of endless ropes or belts are stretched in positions close to both sides, and are circulated by a driving device, and the end side of the unstretched film is inserted between the ropes or belts, gripped, and passed between rollers. . However, since the gripping force of the rope or belt is weak and inconsistent, the unstretched film may fall off from the rope or belt while being conveyed, get wrapped around the roller, and be torn, or the stretching device may be damaged due to the unstretched film being wrapped around the roller and becoming thick. It had the disadvantage that accidents such as breakage often occurred.
前記欠点を解決するため前記ロープ等のかわり

着したフイルム搬送用把持装置が試みられたが、
延伸装置の多能化の影響でフイルム厚が種々ある
場合、フイルム厚みに対応した間隙を有する把持
装置に交換する必要がある。 In order to solve the above-mentioned drawbacks, attempts have been made to develop a gripping device for film transport in which a chain is stretched instead of the rope, and a gripping device that provides a strong gripping force and includes a film holding piece and a rotary claw is attached to the chain. but,
When film thicknesses vary due to the multifunctionality of stretching devices, it is necessary to replace the gripping device with a gripping device that has a gap corresponding to the film thickness.
しかし実際においては回動爪からなる把持装置
の許容しうるフイルム厚みの差は極端に小さく、
その為多数の交換用把持装置を必要とし実用的で
はなかつた。 However, in reality, the difference in film thickness that can be tolerated by a gripping device consisting of rotating claws is extremely small.
Therefore, a large number of replacement gripping devices are required, which is impractical.

A plan view of the embodiment, a Z-Z arrow view in FIG. 2, and a Y-Y arrow view in FIG. 3 are shown, and the configuration will be explained based on the drawings. 1 is an endless chain provided on the side of the stretching roller R, and is moved in the direction of the arrow by a drive device (not shown). Reference numeral 2 denotes a mounting piece provided on the chain 1, to which a film holding piece 3 is attached with a screw 6. Reference numeral 4 denotes a sphere support piece having a sphere support groove h that gradually deepens in the moving direction, and is attached to the film holding piece 3 with a screw 7 so as to have a gap t. Numeral 8 is a screw for adjusting the minimum gap a (0.1 mm) between the film holding piece 3 and the sphere 5 to prevent the sphere from being caught between the sphere supporting grooves of the film holding piece and the sphere supporting piece.

がるので未延伸フイルムＦは容易に挿入できる。 The stretching roller R is rotated at a predetermined speed. The chain 1 can be moved in direction A by a drive device (not shown) at approximately the same circumferential speed as the stretching roller R, and the film gripping device attached to the chain 1 can be moved at the front end of the stretching device. Stop it in the position. In this state, the operator grasps the tip of the unstretched film F discharged from the nozzle, and when the unstretched film is loosened, the unstretched film is placed in the gap t between the film holding piece 3 and the spherical support piece 4 of the gripping device. Insert the tip side part in direction A. When the unstretched film F is inserted, the sphere 5 is pushed in the A direction by the unstretched film F, creating a gap between the sphere 5 and the film holding piece 3, and the sphere 5 rolls on the unstretched film, so that the unstretched film F can be easily inserted.

を次工程の装置へ速かに供給できる。 When the operator inserts the unstretched film F to a predetermined position and further pulls it in the direction B, the sphere 5 rolls along with the unstretched film and moves to the narrow part of the sphere support groove formed in the sphere support piece 4, forming a wedge. The same effect is produced, and the unstretched film F is reliably gripped by the sphere 5 and the film holding piece 3. Thereafter, the endless chain is driven, and the film gripping device that gripped the unstretched film F in the above operation passes between the stretching rollers R of the stretching device to convey the unstretched film F. When the endless chain is stopped by detecting the film gripping device that has reached the rear end of the stretching device, the operator grabs the leading end of the unstretched film F held by the film gripping device and moves it in the direction A, and the sphere 5 also holds the film. It moves in the same direction while rolling on top, creating a gap between the sphere 5 and the film holding piece 3, during which time the film end can be moved toward the roller side in the direction perpendicular to the A direction, and easily removed from the gripping device. This allows the film to be quickly supplied to equipment for the next process.
