2. Description of the Related Art Conventionally, the following mechanism has been known as a packing box packing device for packing packed boxes of barley tea, flour and other products in a corrugated cardboard box. .

1) As in JP-A-4-327103,
The transport table surface is expanded and contracted in the transport direction so that when it is extended, it is transported, and when it is contracted, the packages are dropped from the transport table surface to perform boxing.

2) As in JP-A-62-28307,
Opening / closing valves that open and close downward on both sides in the carrying direction are provided near the ends of the carrying conveyor in the carrying direction, and after the packages conveyed from the carrying conveyor are stocked in the opening / closing valve, the opening / closing valve is opened to open the package. It was made to fall and was packed in a box.

3) As in Japanese Patent Publication No. 56-12531
A slide table that horizontally moves is provided near the end of the transfer conveyor in the transfer direction. After the packages conveyed from the transfer conveyor are stored on the slide table, the slide table is retracted to open the predetermined position. Then, the packaging is dropped and boxed.

4) As shown in FIGS. 5 and 6, a large number of small rollers 31 are attached to a pair of opposed shafts 32 on the surface of the conveyance table, and a large number of shafts 32 to which the small rollers 31 are attached are arranged in the conveyance direction. The shaft 32 is laid and can be moved back and forth by a cylinder 33 or the like which is an air cylinder or the like. Then, at the time of carrying, the pair of opposed shafts 32 are brought close to each other for carrying, and at the time of the boxing operation, the pair of opposed shafts 32 are moved backward by actuating the cylinder 33 to separate the carrying table surface from each other, and the package 34 is moved from the carrying table surface. It is designed to be boxed by dropping.

[0007]

However, each of the above conventional packaging devices for a package has the following drawbacks.

A) As in Japanese Patent Laid-Open No. 4-327103,
In the case where the transport table surface is expanded and contracted in the transport direction, the transport is performed during extension, and the package is dropped from the transport table surface when contracted to perform boxing, the control of the transport table becomes complicated, and There is a drawback that the package is not well aligned because the package falls down from the end in the length direction.

B) As in JP-A-62-28307,
Open / close valves that open and close downward on both sides in the transfer direction are provided near the end of the transfer conveyor in the transfer direction, and the packages conveyed from the transfer conveyor are stocked in the open / close valve, and then the open / close valve is opened to open the package. In the case where the boxes are dropped and the boxes are packed, there is a drawback that the mechanism such as driving and controlling the conveyer, driving and controlling the on-off valve is complicated, and the control is troublesome.

C) As in Japanese Patent Publication No. 56-12531,
A slide table that horizontally moves is provided near the end of the transfer conveyor in the transfer direction. After the packages conveyed from the transfer conveyor are stored on the slide table, the slide table is retracted to open the predetermined position. However, even in the case where the package is dropped and packed in a box, the alignment is not good because the package falls down from the end in the lengthwise direction like the above b). In addition, a plurality of drive systems are required, and the mechanism is complicated and the control is troublesome.

5) As shown in FIGS. 5 and 6, a large number of small rollers 31 are attached to a pair of opposed shafts 32 on the surface of the conveying table, and a large number of shafts 32 to which the small rollers 31 are attached are arranged in the conveying direction. Cylinder 3 if installed
3 is operated and retracted, and when the transport table surface is separated and the package 34 is dropped from the transport table surface, there is a risk of damage to the package 34 due to unnecessary friction being applied to the package 34. There was probably a poor alignment due to such a drop.

The packaging apparatus of the present invention eliminates the above-mentioned drawbacks of the prior art, has a good alignment of the packaging, and has a simple mechanism for driving and controlling the conveyor, which is easy to control. The aim is to provide a packaging device for packages which is very easy to carry out.

[0013]
