[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to a device for packaging objects using a so-called half-folded film made of synthetic resin or the like, and more specifically, to a device for packaging objects using a half-folded film that has improved transportability for objects to be packaged. This invention relates to a product packaging device.

0002

BACKGROUND OF THE INVENTION Conventionally, in a device for packaging an object with a so-called half-fold film made of synthetic resin, etc.
As described in No. 64, in order to make the cross section of the half-folded film so-called U-shaped and to change the flow direction of the film to a direction perpendicular to that from the roll film mechanism, generally two upper and lower right angles are used. A mouth opening mechanism consisting of isosceles triangular members is used, a belt conveyor mechanism for transferring the packaged items is arranged between the members, and each space is provided between the belt conveyor mechanism and each of the above members. A method has been adopted in which the upper and lower pieces of the half-folded film folded back by the opening mechanism are passed through the bag, and the object to be packaged is fed between them.

0003

[Problems to be Solved by the Invention] However, in the above-mentioned conventional packaging apparatus, when an object to be packaged having a long and thin handle, such as a frying pan, is to be packaged, the handle may come into contact with the above-mentioned half-folded film. Because of this, the direction of transport of the packaged items is bent or the packaged items are tilted, which often impedes smooth and regular transfer of the packaged items, and a solution to this problem has been desired.

[0004] Therefore, an object of the present invention is to provide an apparatus for packaging objects using a semi-folded film, which makes it possible to smoothly and regularly transport objects having particularly long protrusions. .

[0005]

[Means for Solving the Problems] The above objects of the present invention are achieved by the following means. That is, the packaging device for an object to be packaged using a half-folded film of the present invention includes a feeding belt conveyor mechanism for transporting the packaged object, a feeding belt conveyor mechanism provided following the feeding belt conveyor mechanism, and the feeding belt. A roll film mechanism consisting of a group of rolls that feeds out a half-folded film substantially perpendicular to the transport direction of the conveyor mechanism, and a right-angled two roll mechanism located in front of the supply of the half-folded film and provided above and below the feeding belt conveyor mechanism. In a packaging device for a packaged object using a half-folded film, which includes an equilateral triangular film opening mechanism and a sealing mechanism for sealing the packaged object,
The sealing mechanism includes a sealing bar provided between the feeding belt conveyor mechanism and the feeding belt conveyor mechanism, and a heat sealing member provided on the sealing bar and capable of being pressed into contact with the sealing bar. The sealing member is characterized in that a cutter 13 is provided to protrude toward the feed belt conveyor mechanism side.

[0006]

[Function] The present invention has the following functions due to the above-mentioned structure. First, the half-folded film fed out in the roll film mechanism is guided to the opening mechanism via appropriate guide rolls, and the feed-out guide of the roll film mechanism is provided by right-angled isosceles triangular members provided above and below the feed belt conveyor mechanism. Since the half-folded film is turned over by one side parallel to the roll and the oblique side continuous with the side, the cross section of the half-folded film becomes U-shaped. The half-folded film is drawn out perpendicularly to the feeding direction, and the leading end of the half-folded film is once sealed by a sealing mechanism provided next to the feeding belt conveyor mechanism. next,
The feeding belt conveyor mechanism is operated, and the object to be packaged on the belt conveyor is put into the film having a U-shaped cross section. If the object to be packaged has an elongated protrusion, the heat sealing member in the sealing mechanism A cut is made in the film by a cutter attached just before (that is, on the side of the film being fed out), and the protrusion passes through the cut.

[0007] Thereafter, the object to be packaged and the film having a U-shaped cross section are automatically transported to the destination by the conveying force of the feeding belt conveyor mechanism, and are sequentially sealed and packaged into a bag shape by the sealing mechanism. .

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained in detail below by way of examples and with reference to the drawings. FIG. 1 shows an outline of a packaging device for an object to be packaged using the semi-folded film F of the present invention. The packaging device includes a roll film mechanism A (not shown), an opening mechanism B, an infeed belt conveyor mechanism C, a seal mechanism D, and an outfeed belt conveyor mechanism E. In the L-shaped sealer 11 having the heat sealing members 12 and 12' of the sealing mechanism D, a cutter 13 is attached in front of the heat sealing member 12 located substantially perpendicular to the film transport direction. The installation position of the cutter 13 is determined as necessary.
It is movable in a direction substantially perpendicular to the film transport direction, and is mounted so that the inside of the blade can be changed as necessary.

FIGS. 2, 3 and 4 show the various stages of operation of the packaging device of the present invention. First, FIG. 2 shows a state in which a packaged object W having a long protrusion placed on the belt conveyor 28 of the feeding belt conveyor mechanism C has not yet been transferred. Here, from the film winding roll 21 of the roll film mechanism A to the various rolls 22, 23 -
The half-folded film F that is fed out through the film 26 is guided to the opening mechanism B via the feeding guide roll 27, and is drawn out in a direction perpendicular to the roll with a U-shaped cross section as will be described later.

Next, the tips of the upper and lower pieces of the half-folded film F are guided onto the seal bar 29. Thereafter, the L-shaped sealer 11 of the sealing mechanism D is swung down in the direction of the arrow on the half-folded film F on the seal bar 29, and the tip of the half-folded film F is sealed by the heat sealing member 12, and at the same time the cutter 13 As a result, a cut is made near the leading edge of the film. In FIG. 3, the feeding belt conveyor mechanism C is operated and the packaged object W on the belt conveyor 28 is shown.
The figure shows a state in which the long protrusion of the packaged object W has passed through the cut after being transferred. FIG. 4 shows that the object W to be packaged is further transferred and is on the belt conveyor 31 of the sealing mechanism D, and the half-folded film F on the seal bar 29 is sealed and cut by the heat sealing member 12 at the rear of the object W to be packaged. At the same time, the cutter 13 is placed on the rear half-folded film F'.
indicates that a cut has been made. At this time, it goes without saying that the side edges of the film F are also sealed by the heat sealing member 12' shown in FIG.

By repeating the operating states shown in FIGS. 2 to 4, the items to be packaged are continuously packaged.

As shown in FIG. 6, the half-folded film F is unwound from the roll film mechanism A, and guided to the opening mechanism B via the unwinding guide roll 27. Figure 5
As shown in , the upper piece f1 of the half-folded film is placed over the upper right-angled isosceles triangular member 14 of the mouth opening mechanism B, and is turned over in the direction of the arrow along the hypotenuse bc, so that one side It is pulled out in a direction perpendicular to ab as shown by the arrow. On the other hand, the lower piece f2 is turned over in the direction of the arrow from the lower side of the lower right-angled isosceles triangular member 15 of the mouth opening mechanism B along the hypotenuse b'c', and the lower piece f2 is turned over in the direction of the arrow along the oblique side b'c'. pulled out at right angles. At this time, the half-folding film F has a U-shaped cross section with f3 as the inner wall. The packaged items W on the belt conveyor 28 are then transferred into the U-shaped portion of the film.

[0013] When the above-mentioned packaging device was used to package items, it was possible to transport the items smoothly and regularly, and the sealing operation could be performed continuously.

[0014]

Effects of the Invention As described above, the device for packaging objects using a half-folded film of the present invention makes a cut in the vicinity of the leading end of the film when sealing the leading end.
In particular, when packaging an object having long protrusions, the protrusion of the object passes through the cut, so that the object can be transferred smoothly and regularly without being hindered by the half-folded film. It has the advantage of being able to be packaged easily, making it possible to carry out efficient packaging operations.
