Description

[Detailed description of the invention] (Field of industrial application) The present invention is for forming a peeling part for peeling off the film in a conical cup-shaped film packaged article such as a conical cup of noodles sealed with a film. Regarding the device.

(Prior Art) Generally, the film of this type of article is peeled off when used, but the relatively thin and elastic film cannot be easily torn off, which tends to cause inconvenience in use. In order to eliminate these inconveniences, we published Utility Model Application No. 59-186262 and Utility Model Application No. 60-
As seen in Japanese Patent No. 11369, it has been proposed to form a cut in a film used to package an article and then apply a label to cover the cut to form a peel-off portion of the film. According to this, when the label is peeled off, the film is lifted together with the label, and the film breaks from the cut, and the film can be easily torn off, which is convenient.

(Problems to be solved by the invention) At the final stage of the manufacturing process of the article, film packaging is applied, and then a peeling part forming device forms cuts in the film and attaches a label. It is desirable that the cut be formed at the bottom of the conical cup so as not to damage the article.Moreover, in order to quickly form the peeled portion in accordance with other manufacturing steps of the article, It is preferable that the material is continuously fed in a constant state of transport.

The present invention aims to provide a device that satisfies these demands.

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a film peeling section of a conical cup-shaped film packaged article by a cut that forms a cut in the film disposed along a transport path of the article. and a label applicator for applying a label to close the cut, the article being transported in an upright position along the front of the transport path of the cutting device. A first removing device for removing the article from the transfer path and a second removing device for removing the article transferred with the large diameter portion facing forward from the transfer path are sequentially provided.

(Function) A conical cup-shaped article wrapped in a film is sequentially fed onto a transfer path in order to form a peeling portion of the film, and a cutting device and a label pasting device arranged along the transfer path cut the film into strips. A peeled portion is formed by forming a cut and pasting a label to close the cut.

Before the articles are sent to the cutting device, the first rejecting device and the second rejecting device remove those in an inappropriate transfer state, that is, those in an upright state and those with the large diameter portion in the front. Items in a conveyed state with the section at the rear are allowed to pass through, and the passing articles are erected with the large diameter section facing down by the article erecting device.

Therefore, articles that stand up with their bottoms facing up can be fed one after another into the cutting device, the film can be cut without damaging the articles, and the subsequent labeling can be done in the standing position, thereby preventing the formation of peeling parts. Can be done quickly.

(Example) A case will be described in which an example of the present invention is applied to a cup of noodles shown in the attached drawing.

1 and 2 show a plan view and a side view of an apparatus for forming a film peeling portion on an article 1 in a conical cup-shaped container sealed with a film, the article 1 being driven by a motor 3 and a 2 The tip end 2 of the transfer path 2 formed by the pair of top chain conveyors 4, 4
a to the rear end portion 2b.

A cutting device 7 and a label pasting device 9 are arranged along the transfer path 2, and as shown in FIGS.
A label 10 is attached to cover the cut 8 to form a peeled portion of the film 1d. If the label 10 is peeled off by holding the part 10a without applying adhesive to the part 10a of the label 10, the film 1d near the cut 8 will be lifted up together with the label 10, and the cut 8 will be broken. As this progresses, the film 1d can be easily removed from the container 1a of the article 1, and this peeling action is similar to that of the above-mentioned known document.

The article 1 is wrapped in a film and supplied to the tip end 2a of the transfer path 2, but the orientation of the article 1 is uneven;
It is difficult to continuously cut the film 1d and attach the label 10 thereto because it faces the direction of transport or stands upright.

Therefore, in the present invention, a first removing device 5a, a second removing device 5b, and an article raising device 6 are sequentially provided along the transfer path 2 in front of the cutting device 7, and the cup-shaped articles 1 are not transported to the cutting device 7. It was designed to be fed in an upright position with its large diameter section facing down.

The first removal device 5a removes the article 1 that is sent standing up on the transfer path 2 to the outside of the transfer path 2, and detects the upright state of the article 1 and the sensor 5c that detects the upright state of the article 1. Bar 5 that prevents the passage of 1
d and an air gun 5e that works in conjunction with the sensor 5c.When an article 1 is sent in an upright state, the bar 5d blocks the article from passing, and at the same time, the sensor 5c detects the object and transports it by blowing air from the air gun 5e. Blow it to the side of path 2 to eliminate it.
As a result, the state of the article 1 passing through the first removal device 5a is either state A with the large diameter part of the article 1 at the rear as shown above the transfer path 2 in FIG. It is limited to state B with the large diameter portion at the front.

The second removing device 5b removes the article 1 in state B that is sent with the large diameter portion in front, and includes a pair of sensors 5f and 5g and an air gun 5h located between them.
The sensor 5f at the front of the transfer path 2 is installed high from the surface of the transfer path 2, and the sensor 5f at the rear is installed high from the surface of the transfer path 2.
g should be installed close to the surface of the transfer path 2,
When both sensors 5f and 5g do not detect the article at the same time, the air gun 5h detects the article 1 in front of it.
was blown off to the side of the transfer path 2 by air blow. Since the sensors 5f and 5g are installed at different heights from the transfer path 2, the above state A
For article 1, both sensors 5f and 5g are applied at the same time.
is activated, therefore, the air gun 5h is deactivated and the article can pass to the next article raising device 6, but for the article 1 in the state B, both sensors 5f and 5g are activated.
do not operate at the same time, air gun 5h operates,
This is removed to the outside of the transfer path 2. Article raising device 6
Only the article 1 in state A is sent to the article 1, and as a result, the article 1 is in an upright state c with the large diameter portion facing downward, as shown above the transfer path 2 in FIG. Therefore, the articles 1 in the upright state C are sent one after another to the cutting device 7, where a U-shaped cut 8, for example, as shown in FIG. 4 is formed by the thermocutter 7a that moves up and down. In this case, a thermo cutter 7a having a U-shaped protrusion 7b as shown in FIG. 5 is used, and when it is electrically heated and lightly brought into contact with the article 1, a cut 8 can be formed on the film 1d. In the illustrated conical cup-shaped article, since there is some gap between the container 1a and the film 1d at the bottom, the container 1a is not damaged when the cut 8 is formed at the bottom.

The article 1 with the cut 8 formed thereon is further sent to a labeling device 9, where a label 10 is stuck so as to cover the cut 8 as shown in FIG. The labeling device 9 used is a known type in which a label-attached mount 9b wound around a reel 9a is fed out onto the article 1, and is pressed and bonded with a press roller 9c.

The article 1 to which the label 10 has been attached is labeled 1
The presence or absence of 0 is checked by the checker 11,
It is sent out from the end 2b of the transfer path 2 to the next process such as boxing.

(Effect of the invention) As described above, according to the present invention, the product in the upright state and the large diameter portion can be removed before the product is sent to the cutting device for forming the peeling part of the film that seals the conical cup-shaped product. Since the articles facing forward are removed by the first and second removal devices, the articles standing upright with their bottoms facing up can be fed into the cutting device one after another, and the film can be cut without damaging the articles. This has the advantage that the subsequent label attachment can be performed in that state and the film peeling portion can be formed quickly.
