The record disc 15 stored in the inner bag 1 is sent to the record storage box 16 side. At the same time, the inner bag storage box 4 moves to a position below the suction cup 2, and the second cycle starts.

Next, by tilting the record shooter 9, the record disc 15 is sent from the record shooter section C to the record packaging section D.

The record boxing section D is a process of storing every 50 records in the inner bag 1 into the storage box 16,
It is constructed as shown in FIGS. 7 and 8. The storage boxes 16 are placed on a pedestal 25 that is moved by a chain 17 and are brought up one after another from below. Each time the motor 18 is retracted,
This is done by rotating the chain 17 a predetermined number of times. 50 sheets count is record shooter 9
This is done by tilting 50 times. 19 is an actuator, and an inner bag 1 containing 50 records contains 15 records.
The uppermost storage box 16 in which is stored is pushed out from the pedestal 25 onto the inclined conveyor 20. This operation of the actuator 19 is performed before the operation of the motor 18. 21 is a lacquer disc, which is about the same size as a record, and is an aluminum disc with lacquer applied to the front and back. The plurality of rack disks 21 are housed in a storage guide frame 22 made up of a plurality of rods, and are sucked one by one by a suction cup 24 at the tip of a rotating supply arm 23, and placed in a storage box 16 on the top stage. will be moved to This movement is performed every time the record shooter 9 is tilted 10 times, that is, every time 10 records 15 in the inner bag 1 are placed in the top storage box 16. It is also done when coming into contact with someone. Particularly in the latter case, a bare record 15 that does not fit into the inner bag 1 is carried, and the record 15 is carried so that the lacquer records are positioned on both sides of the record.

In this record boxing section D, each time the record shooter 9 is tilted, the inner bag 1 containing the record disc 15 enters the storage box 16 at the top. When the record shooter 9 is tilted 10 times, the number is counted, and before the 11th tilt, the supply arm 23 and the suction cup 24 at its tip end the recorder 21.
One sheet is brought in, and the Lutzker board 21 is placed on top of the inner bag 1, which has 10 sheets stacked on top of each other. In this way, the record shooter 9 is counted 50 times when the record shooter 9 is tilted 50 times. Actuator 19 by signal
is activated to push out the uppermost storage box 16 onto the inclined conveyor 20. The storage box 16 placed on the inclined conveyor 20 moves by its own weight and heads to the next storage location. When the actuator 19 returns, the signal causes the motor 18 to rotate a predetermined number of times, which moves the chain 17 and raises the empty storage box 16, which was located just below the top tier, to the top tier. Then, in the same manner as described above, the inner bag 1 containing the record disc 15 starts to be stored in the raised storage box 16. As mentioned above, when the inner bag 1 is set on the record shooter 9 and the opener 11 is operated, the opener 11 does not enter the rim of the inner bag 1, that is, the inner bag 1 is opened. If the operation fails, the opener 11
2, so the signal causes the Lutzker board 21
is carried to the record box 16, and on top of that Lutzker record 21 is a bare record 1 that does not fit into the inner bag 1.
5 is placed on it, and a Lutzker board 21 is placed on top of it.
In other words, if you fail to open the opening of the inner bag 1, the record 15 will not fit there and will be exposed, so for protection, the top and bottom should be sandwiched between the lutzker records 21 when storing it in the record storage box 16. do.
