Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in an automatic film feeding device that uses a conveyance leader to load a film containing a 135 cartridge and feed it easily and reliably to a developing device.

[Conventional technology]

Conventionally, one method for automatically supplying non-containing film to a developing device is to use a conveyance leader with a cartridge attached to a dedicated magazine, one on each side, as in Japanese Patent Application Laid-open No. 61-151654 and No. 62-286048. A method in which pairs are loaded one by one and the magazines are sequentially sent to the developing device, and another method is disclosed in Japanese Patent Application Laid-Open No. 63-23156. Japanese Patent Publication No. 63-583
There is a system, such as No. 47, in which the perforation of a fine feed leader is engaged with a protrusion on an endless belt and driven to transport a cartridge-containing film.

Still another method, as in JP-A-62-246068, is to provide a plurality of loading positions for loading cartridges, for example, on an endless belt, and to attach the cartridge-containing film to which the transport leader loaded therein is attached. Sequentially lf 8■ Into the spinner's interior, the amazing eggplant beak Liao's l, small bar 2 [Problems to be solved by the invention] In the conventional film feeding device as described above, the conveying leader to which the cartridge is joined is used as the film feeding device. When loading, it is necessary to engage the burrows of the conveyance leader with the protrusions on the endless belt at regular intervals, and to load the cartridge by fitting the cartridge to which the leader is attached into a predetermined loading position. One transport leader or cartridge, such as
The work was quite tedious as it required careful positioning.

As you use the reader over and over again, it gradually wears off. When such leaders are put on standby by fitting the protrusions on the endless belt and stacking them one on top of the other, and the leaders are combined with the film containing the rollers one by one and sent to the developing device, there is a risk of peeling due to perforation. The next waiting conveyance leader may also become entangled with the leading conveyance leader and be sent out together. When this happens, the film is damaged by two parts on its way to the developing device.
If it is pulled out too hard, it can sometimes cause fogging and cause serious trouble.

The present invention solves these problems and can store as many cartridge-containing films bonded to a conveying leader as possible, and also allows the reader to be easily and reliably and quickly moved without any special positioning means in the conveying direction of the leader. The object of the present invention is to provide a film feeding device capable of loading film cartridges and cartridges.

[Means to solve the problem]

The purpose of this is to store conveying leaders in which the tongue end of a film containing a cartridge is pasted and combined on at least one side, and a case provided with at least one groove for arranging and storing the cartridges in sequence, and a case containing the film containing a cartridge. a storage unit having a guide impeller for sorting the films one by one, a holding pawl mechanism for a waiting transport leader, and a lid for the case; a sprocket gear for transporting and driving the transport leader; and a cutter for cutting the end of the film. and an insertion section for inserting the cartridge-containing film into the developing device, and when loading the cartridge, the storage section is laid down horizontally and when activated, the storage section is raised and operated. This is accomplished by a feeding device.

〔Example〕

Embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a partially sectional side view of the film feeding device of the present invention, FIG. 2(a) is a partially enlarged side sectional view of the film feeding device, and FIGS. 2(b), (c), (d) ) is a positional relationship diagram of the state of the first conveyance leader and the cartridge-containing film in the feeding device, FIG. 3 is a perspective view of the film feeding device, FIG. 4 is a horizontal cross-sectional view of the presser claw mechanism, and FIG. FIG. 6 is a side sectional view of the claw in a sunken state. However, the invention is of course not limited to this embodiment.

The film supply device 40 is held by a support 46, the cartridge 3 is housed together with the transport leader 2 in a case 41, and the film supply device 40 is locked with a cover 42. The film supply device 40 is attached to the insertion portion 10 of the developing device 1. An arbitrary number of cartridge-containing films 3 are stored in the storage groove 43 inside the case 41. The tongue end portions of each cartridge-containing film 3 are affixed to both sides of the conveyance leader 2, only the leading one of which is shown by a two-dot chain line in FIG. In the center of the portion 2, perforations 1 2a are equally spaced.

Such a conveyance leader 2 and a film cartridge 3 are easily and securely stored in the groove 43 in the case 41 by opening the lid 42 and regulating the width direction with the film supply device 40 held horizontally. The leading cartridge is placed between adjacent blades of the guide impeller 53. The state is then shown in FIG. 2(b). When this happens, the insertion portion 10 of the developing device L will be horizontal and 60° as shown in Figure 1.
As a result, it becomes almost upright and is ready for operation. Then, by pressing a start button (not shown), a start signal is input and the guide impeller 53 rotates around 45'', as shown in FIG.
), and after 456 turns, the state shown in FIG. 2(d) is reached.

As described above, when the cartridge-containing film supply device 40 is in operation, it is almost in a standing state, as shown in FIG. 2(d).
In this state, the cartridge 3 and the transport leader 2 fall downward into the groove 43 and along the upper surface 44 due to their own weight. Therefore, the leading end of the conveying leader 2 is engaged with the sprocket gear 27, and the perforator 2a at the leading end meshes with the teeth of the sprocket gear 27 to be conveyed. Then, the conveying leader 2 is guided between the guides 25 and 26 of the insertion portion IO while moving between the pair of conveying rollers 14a, 14b and the guide I5.
, and is conveyed while being held between the pair of conveyance rollers 1a of the developing device 11.

The cartridge 3 attached to the reader 2 remains in the holder 16. This holder 16 is fitted via a pole slider 18 to two shafts 19 that are fixed to brackets 21 and 22 provided at both ends of the base 13 of the insertion section IO, and is always biased to the right by a spring 20. It is pressed against the right bracket 22 and stopped as shown by the two-dot chain line. Furthermore, the leader 2 is conveyed through the developing device tl by the pair of conveying rollers 1a or other sprocket gears, and at this time, the film is gradually pulled out from the cartridge held in the holder 16. Then, when the conveying leader 2 advances and the leader continues to move through the developing device l after pulling out the film, the cartridge 3 on the holder 16 is pulled by the film, and the cartridge 3 is passed through the receiver 1117 of the holder 16 to the boulder. -16 moves to the left against the biasing spring force, and the holder 16 is at the position shown by the solid line on the left side, although it is not shown in the figure. The bifurcated stopper stops, and the sensor 13a detects the position of the holder 16, and the signal causes the cutter 24 to operate and cut the end of the film from the cartridge. The cut cartridge falls downward through the discharge path 29 and is collected. sensor 13
A microswitch is sufficient for a. The sensor 13a
The guide impeller 53 of the film supply device 4o is actuated by the signal, and the baton with the leading end of the film affixed to the next leading transport leader 2, which is waiting in the state shown in FIGS. 2(a) and 2(b), is activated. The ρ-uninfiltrated film 3 is in a state as shown in FIG.
Then, transport toward the developing device 1 is started.

Now, here, the presser claw machine *SO provided in the supply device 40
This will be explained using FIGS. 3, 4, 5, and 6.

The guide impellers 53 are arranged on the same shaft 55 corresponding to the two grooves 43 that line up the cartridges inside the case 41.
It is provided so that it can be driven. At the center of the shaft 55 and below the upper surface 44, an operating cam 54 of the presser pawl 56 is mounted on the shaft 55.
5 and is integrally fixed with the shaft. Parallel to the shaft 55, an operating support shaft 61 of the presser pawl 56 is fixed at both ends to walls 51, 52 inside the case 41. A bearing of a lever forming the presser pawl 56 is fitted into the shaft, and a helical spring 62 which acts as a compression spring before the torque spring is fitted into the shaft 61, one end of which is connected to the above-mentioned! ! Hole 64 drilled in 52
The other end is hooked onto part of the lever of the presser claw 56. A stop ring 63 is fitted onto the shaft 61, and the lever of the presser pawl 56 is always pressed against the stop ring by a helical spring 62, and the torque of the spring 62 causes the presser pawl 56 to protrude above the upper surface 44. energized. Further, the upper surface 44 is provided with a window hole 66 for a presser claw.

In addition, a sensor 57 that controls ON/OFF rotation of the motor that drives the shaft 55 of the guide impeller 53 is connected to the holder 5.
8 and attached to the wall 52. The sensor 57 is a photoelectric switch that is activated by forming or cutting off a beam by moving the lever of the claw 56 up and down.
The signal controls the motor ON, OFFFL, and rotation of the guide impeller.

By the way, the conveyance leader 2 to which the leading edge of the cartridge-containing film 3 is attached in the supply device 4o to be conveyed next is waiting in the state shown in FIG. The state of 56 is as shown in FIG. 5, and the rear end of the waiting conveyance leader 2 is in the verforation. And as mentioned above, the insertion part 10
When the motor is actuated by the detection signal from the sensor 13m and the guide impeller 53 begins to rotate, the presser claw begins to sink by the cam 54 as shown in FIG. And Figure 2 (c
), the waiting leader starts moving and the sensor 57 turns on.

When the guide vane axle rotates 90 degrees, the cam pushes up the pawl and the sensor 57 turns OFF. This signal causes the motor to stop rotating. At this time, the leading end of the waiting conveyance leader has its perforation engaged with the sprocket gear 27 and starts to smoothly convey to the developing device. And the aforementioned pushed-up claw 5
6 fits into the perforation at the rear end of the conveyance leader 2 that is waiting next, so that it will not be dragged around irregularly by the preceding conveyance leader due to the perforation being torn off or the like.

For this reason, abnormal phenomena such as a cartridge-containing film being conveyed by a conveyance leader, with the leading end of the film affixed to the leader, and waiting to be restrained by the guide impeller 53, being pulled out leaving only the cartridge behind, can be avoided. It will never happen.

In this embodiment, two cartridge-containing films were symmetrically pasted to the transport leader 2, but only one film may be pasted on one side. Further, in this embodiment, the structure is such that a maximum of two cartridges are attached at a time, but it is of course possible to adopt a design in which even more cartridge-containing films are attached to one portion for transport.

In this way, the cartridge-containing film 3 is arranged in the groove 43 provided in the case 41 of the film supply device 40 for the cartridge-containing film, and each of the transport leaders 2 to which the film is attached is placed one on top of the other along the upper surface 44. It can be said that the operation can be easily and reliably handled by anyone. And case 4
When the film supplying device 40 attached to the developing device 1 via the support 46 with a lid 42 attached to the film supplying device 1 is raised from a horizontal state to be ready for operation, the film supplying device 40 is placed against the upper surface of the developing device 1. Since it is set in an almost standing position at 60° to 90°, the installation space is saved and it is economical. Moreover, it becomes possible to reliably and safely transport the film contained in the cartridge into the developing device l.

The conveyance leaders are also separated safely and reliably without becoming entangled with each other due to the peeling of their perforations, and are sent one by one to the insertion section and the developing device.

〔Effect of the invention〕

According to the present invention, the cartridge-containing film is easily stored in the film supply device together with its transport leader, and by attaching the device to the developing device insertion section, the leaders are no longer tangled with each other, and smooth development is ensured. , a small installation space is now sufficient.
