Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sheet film separation and supply device that separates and supplies stacked sheet films one by one.

[Conventional technology]

The conventional sheet film separation and supply device separates and transports one film by (a) opening a part of the window of a magazine containing multiple sheets of unexposed film;
Some methods use a suction cup such as a rubber to suck the top layer of the stacked film, and then separate and feed the film one by one. A method in which the film is kept in a curved state and separated and fed out one by one using another film pull-out claw (Special Publication No. 56-33302)
(see Publication No.) has been adopted.

[Problem that the invention attempts to solve]

However, the former (a) adsorption-type sheet film separation and supply device requires a moving range for the suction cup and lacks compactness. Since precision is required for the locus of the arm and link that drives the suction cup, precision is required for each component individually, and it is also necessary to provide an adjustment mechanism. A separation plate for separating two sheets is also required. If the suction force of the suction cup is weak, it will not stick, and if the suction force is strong, pressure will be generated on the film, resulting in variations in quality. There are many parts such as suction cups, arms, links, drive motors, detectors, solenoid valves, suction pump separation plates, etc., resulting in high costs. Depending on the number of films stored, the position at the time of film adsorption differs, causing problems such as fluctuations in conditions, and the latter (b).
In the sheet film separation and supply device using hooking claws, when the film is hooked by the needle-like film hooking claws, scratches occur on the film, and scraps are carried into various places. There are problems such as difficulty in adjusting the needle-shaped film hook.

Therefore, the present invention solves the problems of the conventional device and provides a sheet film separation and supply device that reliably separates stacked films one by one and does not cause actual damage such as scratches or pressure to the film. The purpose is to

[Means for solving problems]

In order to achieve the above object, the present invention provides an apparatus for sequentially separating and feeding out the uppermost film of sheet films stacked on a film stand, in which the film is separated from both sides of the rear end of the film on both sides of the film stand. A film hooking member having a step smaller than the width of one film that slides inward is provided, and a laminated film is placed at the bottom of the film stand so that the uppermost film is always in contact with the lower surface of the step of the film hooking member. A spring member is provided to push up the film through the film stand, and a film presser is provided above the center of the rear end of the film between the two film hooking members to constantly push the top film downward to the extent that it does not fall down. A film feed claw is provided above between the hook member and the film presser for hooking and feeding the curved portion of the uppermost film formed by the sliding operation of the film hook member toward the film side. It is something.

[Effect]

The films stacked on the film stand are pushed up by a spring member and are constantly brought into contact with the stepped lower surfaces of the upper film presser and the film hook members on both sides thereof. In this state, both film hooking members slide inward of the film, and the stepped portions of the hooking members move both rear ends of the uppermost film inward, forming two curved portions of the film. Next, the curved portion thus formed is pushed by two film feeding claws and supplied to the outside of the apparatus.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

First, an embodiment of the present invention will be explained with reference to FIGS. 1 and 2. A plurality of sheet films 2 are stacked on a film stand 1, and both rear ends of the films 2 on the film stand 1 are Film hooking shafts 3, 3 serving as film hooking members are provided. The film hooking shafts 3, 3 are inserted through the frame 4 and the bracket 5 attached thereto, and are provided so as to be slidable in a direction perpendicular to the film feeding direction. Step portions 3a, 3a having a step A smaller than that of the two sheets are formed. On the other hand, above the film 2, in the center between the film hooking shafts 3, 3, there is provided a film presser 6 whose lower surface is set at approximately the same height as the lower surfaces of the stepped portions 3a, 3a, and the film presser 6 is used to hold the stacked films 2. The central part of the rear end is pressed down from above. Further, at the lower part of the film stand 1, the film stand 1 is pushed upward, and the laminated film 2 placed thereon is hooked onto the lower surface of the stepped portions 3a, 3a of the shafts 3, 3 and the film presser 6. A plate spring 7 is provided to constantly press the lower surface.

However, when the film hooking shafts 3, 3 are slid toward the inside of the film, both rear ends of the film 2 located at the top are moved inward by the stepped portions 3a, 3a of the shafts 3, 3.
By the film presser 6 that presses the center from above,
At the rear end of the film, as shown by the two-dot chain line in FIG.
Two curved portions 2a, 2a are formed.

Two film feed pawls 8, 8 that move back and forth are provided between the shafts 3, 3 on the film 2 and the film presser 6.
8, the curved portions 2a, 2a at the rear end of the film are
The uppermost film 2 is fed out of the apparatus.

At this time, the film hooking shafts 3, 3
The driving inward of the film and the driving of the film feeding claws 8, 8 in the forward direction of the apparatus (that is, the film feeding direction) are performed integrally.

Next, FIGS. 3 and 4 show another embodiment of the present invention, in which the film hooking shaft 3,
3, film hooking discs 9, 9 are arranged in which step portions 9a, 9a having a step A smaller than one film are formed on the film direction side.

As shown in FIG. 3, the film hooking disc 9 is fixed on the upper part of a shaft 11 rotatably mounted on a seat plate 10 fixed to the frame 4.
When the discs 9, 9 are not fed out, the stepped portions 9 of the discs 9, 9
The lower surfaces of the film presser 6 and the lower surfaces of the film presser 6 press the upper surface of the laminated film 2 which has been pushed up through the film stand 1 by the leaf spring 7.

Then, when feeding out film 2, the fourth
As shown by arrows in the figure, film hooking disks 9, 9
are rotated toward the inside of the film 2, and the uppermost film 2 is hooked on the stepped portions 9a, 9a.
As in the above embodiment, each curved portion 2 is curved at two places.
a, 2a are caught by film feed claws 8, 8 and fed out. At this time as well, the rotation of the film hooking disks 9, 9 and the driving of the film feed claws 8, 8 in the forward direction of the apparatus (ie, in the film feed direction) are performed integrally.

[Effect of idea]

As described above, the device of the present invention is provided with the uppermost film hook member that slides inward from both sides of the rear end of the film on both sides of the film stand on which sheet films are stacked, and at the bottom of the film stand where the film stack is stacked. A spring member for pushing up the film is provided, a film presser is provided between the two film hooking members to constantly press the uppermost film downward, and the film hooking member is disposed above between the film hooking member and the film presser. Since the film feeding claw is provided to hook and feed the uppermost film curved by the film, it is possible to reliably separate one layer of the stacked film.
Moreover, it does not cause actual damage to the film such as scratches or pressure.
