Description

[Detailed description of the invention] It is related to

Fig. 1 is a system diagram of a conventional sterilization equipment for sealed packages, where 01 is a filling-sealing machine, and the filling-sealing machine Ol is
A sealed package (not shown) filled with various contents and sealed (for example, retort pouch food, etc.) is discharged to an empty tray 04 on a conveyor 03 via a discharge device 02. Also, 05 is a tray stacking device.

The tray stacking device 05 stacks a predetermined number of trays 06 containing sealed packages. As this device, for example, there is a known device which stacks two trays 06 one by one, as described in Japanese Patent Publication No. 55-25090. Further, 07 is a pool conveyor, and the pool conveyor 07 pools a predetermined number of stacked trays 09 stacked in a predetermined number by the tray stacking device 05. Also, 010 is a sterilizer;

The stacked trays 09 are stored, sterilized with high-pressure steam or hot water 7, and after cooling are discharged to the pool conveyor 011. 012 is still the tray unloading device.

The tray unloading device 012 includes the tray stacking device 0.
5, the sterilized stacked trays 09 are unloaded onto the conveyor 013 one by one from above. This device is described, for example, in Japanese Patent Publication No. 55-25090. The shredder 014 is a package take-out device, which takes out the sealed package from the tray 06 conveyed by the conveyor 013 and transfers it to a packaging machine such as a drying device (not shown). On the other hand, the empty tray 04 is transferred to the filling and sealing machine 6 using a cart (not shown) or the like.
It is designed to be transported to the upstream part of 1.

The sterilization processing apparatus for sealed packages has a pool conveyor o7 for temporarily pooling stacked trays o9 before sterilization processing on the upstream side of the sterilizer 010, and also arranges stacked trays 09 after sterilization processing on the F stream side. Temporary pool (pool conveyor 011 is installed).

Although the work of carrying in and out of the sterilizer 010 has been automated, a secondary problem has arisen.

1) After starting operation of the filling and sealing machine o1, the tray o6 containing the sealed packages is transferred to the conveyor 01 via the sterilizer 010.
It took almost an hour to reach 3.

On the packaging machine side, such as the package 1 lifting device 014 and the drying device,
Only then will operation begin.

In other words, there is a time difference in the start time of operation between the filling/sealing machine 01 and the packaging machine, and it is necessary to adjust the dispatch time between the filling and sealing machine 01 and the packaging machine, which is not desirable in terms of labor management. As a countermeasure for this, the sterilization processing equipment pools the sterilized stacked trays 09 and trays o6 on the pool conveyor o11 and the conveyor/bearer 013 until the next morning, but the capacity is insufficient. In particular, the larger the sterilizer, the larger the time difference.

Yong L's weak legs were becoming a big problem.

II) The empty tray o4, which has been empty after the sealed packages are taken out by the package take-out device 014, must be placed on a trolley in a predetermined number and transported to the filling and sealing machine 0], which requires manual labor. However, automation has not been achieved here.

111) Furthermore, even if the package unloading device 014 is out of order or the packaging machine in the subsequent process is stopped, the pool conveyor 011 and transport conveyor 013 are designed to pool the stacked trays 09 and trays o6. Regardless, it becomes impossible to supply the empty tray 04 to the filling and sealing machine 01.

As a result, the operation of the filling and sealing machine 01 had to be stopped, reducing production efficiency.

The present invention has been proposed in view of the above-mentioned points, and includes a sterilizer for sealed packages arranged between a filling and sealing device and a packaging device, and a pool conveyor for pooling stacked trays upstream of the sterilizer. Connect.
