Further, the core pipe discharging means 4 may use a motor drive in place of the rodless cylinder described above, and the drive unit 13 may be provided with a hydraulic pressure on the fulcrum shaft 11 in place of the cylinder. The motor or the like may be directly connected, or may be arranged on the side of the core tube receiving tray 2.

As shown in FIG. 4, the packaging machine 31 has a supply-side upper film roll 33 placed at a supply position C1 above a first conveyor 32 disposed inside a main body 31a, and a lower part below the first conveyor 32. The supply-side lower film roll 34 is placed at the supply position C2 of (1).

The supply-side upper film roll 33 is formed by winding a supply upper film 33a around a core tube T, and is rotatably supported by a pair of receiving rollers 35. It is provided as possible.

The supply-side lower film roll 34 is formed by winding a supply lower film 34a around a core tube T, and is rotatably supported by a pair of receiving rollers 36. It is provided as possible.

The upper supply film 33a can be supplied to the second conveyor 39 by a pinch roller 38 via a plurality of guide rollers 37, and the lower supply film 34a
Similarly, it can be supplied to the second conveyor 39 by a pinch roller 41 via a plurality of guide rollers 40.

Between each of the pinch rollers 38, 41 and the second conveyor 39, there is provided a thermal welding and cutting mechanism 42A, 42B for separating, for example, a vertical seal and unnecessary portions of the upper supply film 33a and the lower supply film 34a. They are arranged at intervals in the vertical direction. Reference numeral 43 denotes a press for compressing the article to be packaged which has entered the second conveyor 39.

A standby position D1 approaching the supply position C1 where the supply-side upper film roll 33 is placed, and a standby position D2 approaching the supply position C2 where the supply-side lower film roll 34 is placed, respectively. Film cassette 5
One is placed.

The spare film cassette 51 is mounted on the transport stand 5
2. Sealing bar 53 and film roll support 54
Is a main part, and a preliminary film roll 55 is placed on the roll support 54.

The sealing bar 53 and the sealing bar 56 with a cylinder facing the sealing bar 53 constitute an automatic film splicing device 57. Automatic splicing is performed between the start end of the preliminary film 55a and the end of the supply films 33a and 34a of each supply film roll.

Next, the operation of the above embodiment will be described.

When the packaging machine 31 is driven, the packaging process of a large number of objects to be packaged progresses, and the remaining amount of the supply upper film 33a wound around the core tube T of the supply-side upper film roll 33 decreases, and the end of the supply upper film 33a decreases. When the unit is detected by the detecting means (not shown), the control unit outputs a connection command signal to the automatic film splicing device 57 based on the detection signal, so that the end portion of the supply upper film 33a and the spare film 55a Is connected to the start end. Thereafter, the core tube T left at the supply position C1 is expanded by the inter-axis distance of the receiving roller 35 being expanded by an input signal from the control unit.
It is discharged as a falling core tube T1 below the supply position C1.

When the falling core tube detector 3 detects that the falling core tube T1 has fallen onto the core tube receiving tray 2, the control unit issues a discharging operation command to the core tube discharging means 4 based on the detection signal. When the signal is output, the falling core tube T1 on the core tube receiving tray 2 is discharged out of the machine by the hook 10 as the collection core tube T2, and the core tube storage means 5 previously set at the collection position A is standby. Is fed laterally into the inside of the core tube box 12.

Following this core tube discharging operation, the core tube discharging means 4
When the hook 10 is retracted to the original position, the drive unit 13 is shortened based on the program stored in advance, and the core tube box 12 is rotated from the collection position A to the storage position B, and the core tube is rotated. The collection core tube T2 sent into the box 12 is stored in a state where the direction is changed in the vertical direction.

The subsequent operation of the falling core tube T1 is repeated so that the plurality of falling core tubes T1
Since the storage core tube T2 is stored outside the storage core tube 1, the collection core tube T2 can be collected with a small effort.

If the detection signal of the recovery core tube detector 6 is linked to the above-mentioned notifying means (not shown), the packaging machine 3
Even when a small number of workers handle 1, it is possible to strongly alert the worker during patrol.

Further, in this embodiment, the case where the automatic collecting apparatus 1 is provided on the upper film roll 33 on the supply side has been described. However, when there is room in the height from the bottom to the floor of the packaging machine 31, As shown by 101 in FIG. 4, the present invention can be applied to the lower film roll 34 on the supply side.

[0037]

[Effect of the invention] This invention is based on the idea that used core pipes generated sequentially from the packaging machine are discharged to the outside of the machine each time and collected.
In addition, since a plurality of bottles are stored outside the machine, internal trouble of the packaging machine due to forgetting to remove a used core tube, and labor burden due to work at heights and reinforcement of patrol are eliminated.

Therefore, not only is the operating rate of the packaging machine and the safety of the work contents improved, but also there are excellent advantages such that the operation can be performed with a margin even in a business place where the number of staff is small.
