[Work]

The operation of the film cassette automatic disassembling and sorting apparatus configured as described above is as follows.

When a large number of used film cassettes are placed in the storage chamber of the feeder and the feeder is started and the bottom plate is rotated, the film cassette that receives centrifugal force moves along the feed path and is transferred from the feed port to the carry-in device. Listed.

The film cassettes transferred from the horizontal transport section to the vertical transport section of the carry-in device are accumulated in the vertical transport section, and when the cumulative height becomes higher than the lower limit, the downstream automatic disassembling apparatus is operated.

When the cumulative height of the film cassette is higher than the upper limit while the automatic disassembling device is operating, the operation of the feeder is temporarily stopped, and when the cumulative height of the film cassette is lower than the lower limit, the automatic disassembling device is temporarily stopped, and the feeder and the automatic disassembling device are stopped. And the line balance is done.

The film cassette is inserted from the lower end of the vertical transport unit through the supply port of the automatic disassembling device into the accommodating recess of the rotating disc.

As the rotating disk rotates, both ends of the film cassette in the storage recess are clamped by the pressing member and the pressure contact member, and when the storage recess moves down, the pressing member presses the spool in the case of the film cassette, And one of the lids moves while being in contact with the pressure contact member side.

When the rotating disk is near the lower end, the pressure contact member retracts, one of the lids falls out of the accommodating recess, and falls onto the lid chute.

The case and spool of the film cassette left in the accommodating recess are dropped and transferred to the case transport conveyor when the accommodating recess reaches the bottom end.

Air is ejected from the nozzles toward the case being transferred to the case transfer conveyor, is blown off by the spool chute and transferred to the spool chute, and is further sent to the spool selection conveyor.

The case left on the case conveyor is discharged from the carry-out end.

Thus, the film cassette has one lid, spool,
Disassembled and sorted into cases.

If one of the lids is dropped onto the case transport conveyor together with the spool without falling off to the spool selection conveyor, the lid will drop during traveling of the endless round belt and will be collected on the inclined chute. Only spools are sorted and supplied to the end.

When the method of separating and collecting the spool together with the one lid from the accommodation recess is adopted, the one lid and the spool are selected on the spool selection conveyor, so that the nozzle for blowing the spool from the case transport conveyor is not necessary.

Next, the operation of the film cassette automatic disassembling and sorting apparatus configured as described above will be described.

Used film cassette F in the accommodation chamber 14 of the feeder A
When the automatic operation is started by pushing the push buttons of the operation panel 81, the motor 5 rotates the storage chamber 14 and the motor 19 rotates the bottom plate 20, so that the film cassette F receiving the centrifugal force is stored. The inclined wall 16 of the chamber 14 is raised and is conveyed toward the supply port 21 while being arranged in the supply path 17.

The film cassette F transferred from the supply port 21 to the belt conveyor 24 of the carry-in device C is conveyed while the axis of the film cassette F is oriented in the conveying direction, and is dropped and transferred from the carry-out end to the belt conveyor 25.

The film cassette F on the belt conveyor 25 is transported with the axis of the film cassette F oriented in the direction perpendicular to the transport direction, falls into the upper opening of the vertical transport device 23, and is accumulated in the vertical transport device 23.

When the cumulative height of the film cassette F becomes higher than the lower limit sensor 28, the automatic disassembling device B is detected by the detection signal of the lower limit sensor 28.
Since the motor 31 of starts and the rotating disk 37 starts to rotate,
The film cassette F at the lowermost end in the vertical transport device 23 is a carry-in entrance.
It is fitted into the accommodation recess 38 via 26.

In this embodiment, the film cassette F is placed in the uppermost accommodation recess 38.
, But the recess 38 is lower than the top.
You may make it insert from an oblique direction.

When the cumulative height of the film cassette F becomes higher than the upper limit sensor 27, the motors 5 and 19 of the feeder A are temporarily stopped by the detection signal of the upper limit sensor 27, and the line balance between the feeder A and the automatic disassembling apparatus B is achieved. .

The axial center of the film cassette F fitted in the accommodating recess 38 is oriented parallel to the rotary shaft 34, and both ends of the film cassette F and the pressing member 42 are pressed against each other.
By being rotated by the rotating disk 37 while being sandwiched by 47, the guide plate 39 moves downward while being prevented from falling off.

As the film cassette F in the housing recess 38 descends, the pushing member 42 pushes the spool 2 of the film cassette F, and the spool 2 separated from the case 1 and one lid 3
Although the press contact piece 51 of the press contact member 47 pushed back against the spring 52 retreats, the press member 42 retreats and most of the spool 2 re-enters the case 1, and then the press contact member 47 moves. The lid 3 moves backward and one of the lids 3 falls from the rotary disc 37.

The one lid 3 that has fallen is slid on the lid chute 53 and is collected.

When the accommodating recess 38 reaches the lowermost end, the case 1 that is not constrained by the guide plate 39 is transferred together with the spool 2 to the case mounting table 65 of the case transfer conveyor 54, and the case 1 is transferred while being pressed by the case pressing plate 66. At this time, the spool 2 is blown off to the spool chute 56 by the air ejected from the nozzle 55, and the spool chute 56
The slide 56 is carried to the spool selection conveyor 57.

Air is ejected from the lower nozzle onto the spool 2 placed on the endless round belt 74 of the spool selection conveyor 57, and when one of the lids 3 is conveyed while being attached to the spool 2, the lid 3 is damaged by an air pressure. Is dropped and glides on the inclined chute 80 to be collected.

Therefore, the spool 2 and the lid 3 are reliably selected.

The case 1 falls at the carry-out end of the case conveyor 54 and is collected.

In the embodiment described above, in the automatic disassembling apparatus B, one of the lids 3 is pushed out by the pushing member 42 to be removed, and then in the sorting apparatus D, of the case 1 and the spool 2 transferred to the case transport conveyor 54. Although only the spool 2 was blown off by the nozzle 55 and separated, it can be disassembled and sorted by the second embodiment as described below.

That is, in the automatic disassembling apparatus B, the one lid 3 and the spool 2 are extruded by the pushing member 42, dropped and supplied to the spool chute 56, and the spool chute 56 selects the sorting conveyor 57.
If the spool 2 and the lid 3 on one side are sorted by the sorting conveyor 57 and the case 1 is collected by the case transporting conveyor 54, there is an advantage that sorting can be performed without installing the nozzle 55.

By either of the first and second methods, the film cassette F is continuously and automatically and efficiently disassembled and selected, so that it is possible to reuse the resources of the film cassette F which has not been possible until now. The case 1 and the lid 3 are reused as iron materials, and the spool 2 is effectively reused as a bulking material mixed with polystyrene.

〔The invention's effect〕
