Description

DETAILED DESCRIPTION OF THE INVENTION The present invention generally relates to a series of packaging bags on a vehicle that, in use, are continuously advanced to a filling location.

More particularly, the present invention relates to a series of taped, stacked bags for feeding into a taped bag filling machine.

In the field of packaged goods, such as food products for example, it is known to place the goods in plastic bags and then seal the bags. In order to avoid deterioration of the foodstuff in the sealed bag, it is also known to carry out the sealing operation in a vacuum chamber in which the residual ambient air inside the bag can be sucked out and the bag sealed under reduced pressure conditions.

made of a flexible heat-shrinkable film material by feeding the bags to a bag filling machine in the form of a continuous chain of individual bags carried releasably on an adhesive-coated support tape. It is known to fill packaging bags with products. The product to be packaged is conveyed to a filling station, generally by feeding it on a conveyor belt to a guide, from which the product is filled into the first bag in the chain, after the bag has been opened, for example by an air blowing jet. . The bag filling device receives the bags that have been stacked or stacked on top of each other, and then the bag filling device is sent to a worker or some means of advancing the product to stack the first filled bags. The bag can then be removed from the chain and subsequent bags can be inflated and filled. Feeding the bags in a staggered arrangement in a taped chain provides greater benefits than feeding the bags one at a time to the filling device.

SUMMARY OF THE INVENTION The object of the present invention is to provide a packaging device which allows a faster and more economical operation for filling goods into bags which are fed to a filling station in the form of a series of bags. Such equipment also provides C during the vacuum packaging and sealing stage.
The purpose is to make it possible to speed up packaging operations.

The disclosure of U.S. Pat.

The object of the present invention is to provide a multi-bag conveying device which can be handled as a single bag when continuously supplied to a bag filling device, thereby increasing the output from the filling device. It is said that

That is, the invention consists of a plurality of multi-bag units each containing a separable chain of bags sealed with a bag, the plurality of units being arranged in succession on a conveying device so that one can be removed. We offer a series of packaging bags that are more than capable of being attached to it.

Preferably, the multiple bag units are stacked lengthwise on the carrier tape in a tiled manner and the bags are separable by perforation lines.

The present invention further provides that the bag each containing a portion of
a series of multiple bag units comprising a J-capable chain, the units being serially arranged on and removably affixed thereto; sending said series of multiple bag units to a filling location; and when each unit is submitted to the filling location, inflating each unit bag submitted to the filling location; filling each submitted unit bag with the product; /IV to advance each unit to the place where the bag is closed.
We provide a packaging method for this purpose.

The embodiments shown in the drawings will be explained in more detail below.

With particular reference to the drawings, FIG. 1 shows a conventional series 1 of plastic bags sealed on the four-perforated side, of indeterminate length, for example made of polyethylene.
It shows 0. Bags in this series, such as bags 11 and 12, have side seals 14 on either side of perforations 170.
and 15, and can be separated by a line of perforations 17.

For example, the bag 11 is defined by side seals 13 and 14, a fold line 18 and a flared edge opening 16.

Such a series of bags can be produced in a conventional manner, for example by first extruding a plastic tube, then, optionally after orientation, collapsing the tube into a flattened state and cutting it along the first fold line. can be laterally opened and separated by a line of perforations by creating a mouth and forming regularly repeated lateral seals and perforation lines along the collapsed tube, for example by impact current welding. By producing a series of side-sealed bags? , V construction is possible. Series of such side-sealed bags, starting point for the application of the present invention 4]
It is a fee.

Generally, the component bags within a discontinuation series can be separated. That is, individual bags can be separated from adjacent bags by pulling along a predetermined weakly woven cotton. Preferably, such weakened line is a perforation line as described above. Other schemes include, for example, lines marked with sushi with or without sushi completely attached to one of the series (III).

2A and 28, for definitional purposes:
A typical example of a multi-bag unit is shown below. In FIG. 2A, there are two bags having component bags 26 and 27 which are separated together from the lantern 1 of the bag sealed on the side facing the perforations by separate ties at perforations 34 and 35. A multiple bag unit 25 is shown. The bag 26 has, for example, a flared edge opening 28, a fold 29 and side seals 30 and 33 as described above.

At the joint between the two bags constituting the multi-bag unit, there are seals 30 and 31 on the sides aligned with the line of perforation 32. However, the perforation line 320 is partially separated, as shown between points A and B. Preferably, the partial separation between bags within a multi-bag unit is symmetrical with respect to the length of the fort as shown. In some cases, the partial separation may even be asymmetrical, such that it begins at the edges of the multi-bag unit. Thus, in the illustrated example, bags 26 and 27 are held together by perforations 36 and 37 to unite this multi-bag unit. In FIG. 2B, component bag 46.
A three bag multiple bag unit 45 having 47 and 48 is shown. The individual bags within unit 45 are described with reference to FIG. 2A.
As shown in section AB, it is partially separated along each perforation line. Multiple bags consisting of any number of bags may be used.

The bags are preferably used by stacking them vertically on a carrier tape, thereby making a series of such multiple bags taped together essentially a single bag during filling, vacuuming and sealing. It is possible to feed it into a conventional taped bag filling machine with the advantage that it can be handled in the same way, thereby increasing the productivity of the packaging operation accordingly. In some cases, the sealing operation may include trimming excess material beyond the outermost seal of each unit. After sealing the filled bag,
The individual bags within the unit can be easily separated due to the partial separation that exists along the perforation lines that define the boundaries of the bags within the multi-bag.

The component bags can be easily separated from each multi-bag at any time after the packaging operation if desired, such as immediately after vacuum suction and sealing, or during sale by the retailer, or by the end user thereafter. can do.
