Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a packaging method suitable for packaging granular materials, liquid-containing materials, etc. in bags.

Particulate matter and liquids spill out of the bag when it is turned sideways, so the bag must be packed in an upright position.

Conventionally, both corners of the mouth edge of the bag are held between a pair of mechanical chucks, and the bag is transported in a suspended state by the rotation of a rotor that supports the chucks, and the packaged items are supplied midway through the driving trajectory. , replenishment of liquid, heat sealing of the bag opening, etc. have been provided. However, if you try to automatically hold the bag with the chuck, a certain percentage of chuck errors will inevitably occur and packaging problems will occur. falls.

The present invention has the above-mentioned points (: formation of a recess for supporting the handbag).
A bag is placed in each of a plurality of bag support cups,
While the cup is being conveyed by a conveyor, the bag inside the cup is wrapped, so that the bag can be wrapped without using a zipper.

Embodiments of the present invention will be described below based on the drawings.

Figures 1 and 2 (1) is a belt conveyor placed horizontally. A pair of parallel guides (21i3) are provided at the top of the conveyor, and bag support is provided between these guides. It forms a track for transporting the bags Q contained in the cups (4).At one end of the guides 12) and 13), there is a side of the belt conveyor (1) (=a supply conveyor I opposite the conveyor). In addition, from the supply conveyor I toward the turntable (5) provided at the end of the main conveyor (1), a packaged material supply hopper (6) and a liquid filling tube (7) are installed between the guides. , heated sieve (

...is formed.

On the other hand, the bag support cup (4) has a rectangular shape in whole or in part, and as shown in FIG. 3, a recess for supporting the bag is formed from the top surface toward the inside.

The apparatus for carrying out the present invention is constructed as described above, and its operation will be explained below.

The shape of the bag is approximately as shown in Figures 4 to 6.

The recess (11) in the cup (4) shown in FIG. 3 is shaped so that these bags can sit comfortably on it. In particular, the bags shown in Figures 5 and 6 have a good shape on the bottom so that they are stable in the cup, but the flat bag shown in Figure 4 is unstable, so it is necessary to It is desirable to store the packaged item (b) as shown in the figure.

and a number of cups 141141 each supporting a bag
When ... is supplied onto a continuously rotating supply conveyor,
Each cup is conveyed in a line by the conveyor, and the first cup runs onto the main conveyor (1) and collides with the guide (3) and stops.

On the other hand, the main conveyor (1) rotates intermittently at predetermined time intervals, and the top cup (4) is hooked onto the hook element Uυ.
Hook it up, drive it to the bottom of the hopper (6), and stop.

The hopper (6) is temporarily lowered by the device L9 and its mouth is inserted into the bag, so that the object to be packaged is supplied into the bag through the hopper (6). However, as shown in FIG. In the case of a flat bag, the material to be packaged is filled in advance, so it passes under the hopper 16) and the liquid filling tube (7)
The vehicle was driven to the bottom and refilled with flavored liquid. The rotation of the main conveyor (1) causes the cup (4) to further seek t.

The secondary heating seeker 181191 approaches by t2, and the mouth of the bag is melt-sealed by i2. And more cups (4)
is carried out from the main conveyor ( ) onto the turntable (5).

Although the transport trajectory of the cup (4) is illustrated as a straight line as an example, it goes without saying that the cup may be transported along a circular track. This can also be used as a vacuum packaging method.

As described above, the packaging method of the present invention involves holding the bag in a bag support cup (4) that is entirely or partially square in planar shape, and holding the square portions of a large number of cups on both sides. The bag is transported between the parallel guides 121 and 2 (Ta2), and packaging work is carried out on the bag C during the transport, and the bag can be supported and transported without using a mechanical chuck device. This has the effect of eliminating troubles caused by mischucks and allowing smooth packaging work.
