Abstract

PURPOSE:To prevent characters, etc., printed on a label from blotting or disappearing by arranging a labeling mechanism so that the last folded end of a film labels the overlapping end. CONSTITUTION:When a label (d) is stuck after packing on a folded end (e), with which the folded end (k) of a film overlaps, an electromagnetic brake 31 is released to operate as an electromagnetic clutch 20 operates, and because a carrying roll 19 and a biasing roll 32 rotate while holding it between them, a mount 12, on which a label (d) is stuck, is pulled out from a label roll at the same speed as the feed rate of a film. The mount 12 with the label (d) stuck thereon is bent sharply by the tip of a folding guide plate 34 and, with this folding, the label (d) is gradually peeled from the mount 12 and stuck on the film. The mount 12 is wound by a take-up roll 26 via the carrying roll 19 and the label (d) stuck on the film is lightly pressed by a sponge roll 43.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a labeling device for a packaging machine that automatically wraps trays containing items such as meat, fish, vegetables, fruits, etc. using stretch film, shrink film, etc. It is something.

[Conventional technology]

Conventionally, as a packaging machine that automatically wraps trays containing items of this kind with a film, for example, Japanese Patent Application Laid-Open No. 63-27
2616, etc., a tray containing items is transferred by a conveyance mechanism, placed on a pedestal below a predetermined packaging section position, and the pedestal is raised to abut against the film and the film is placed on the tray. A packaging machine is known in which the tray containing the wrapped item is conveyed out after wrapping the item by folding it into the bottom of the item.

Other automatic packaging machines, such as those disclosed in Japanese Utility Model Publication No. 60-38481, Japanese Utility Model Publication No. 6231361, and Japanese Utility Model Publication No. 63-28081, are capable of transporting trays containing articles while simultaneously transferring film to the tray. There is a known packaging machine that wraps the cylindrical film around the film in a cylindrical shape and then folds both ends of the cylindrical film around the m(II+) of the tray.

In the above-mentioned packaging machine, after wrapping the tray containing the item in a film, a label is attached to the surface of the film with information such as the contents of the package, date of manufacture, content amount, etc. In some cases, it is time-consuming to do it manually, so for example, it is recommended to combine the automatic label pasting device known from Japanese Utility Model Application Publication No. 62-62606 and Japanese Utility Model Application Publication No. 62-19909 with the above-mentioned automatic packaging machine. Therefore, the labeling process is done at the same time as the packaging of the item.

The packaging process of these conventional structures is illustrated in FIGS. 8 to 15, for example.
16 and 17.

In the packaging process shown in FIGS. 8 to 15, first, as shown in FIG. , the article W, in this case the tray containing the article is transferred onto the pedestal a, the left and right edges of the film F in the feeding direction are held between a pair of upper and lower clamping belts b, and the film F is fed onto the article W.
Cut-off perforations C are made in advance at the positions of one package, and the contents of the package and the date of manufacture are displayed, and a label d (not shown) on which weight, price, etc. is printed is pasted. As shown in Fig. 1O111, the film F is pasted by a mechanism, and the pedestal a is pushed up to cover the upper surface of the article W in a stretched state, and the rear side and both left and right ends e of the film F in the transport direction are pasted.
-f and -g are folded into the bottom surface of the article W by advancing their respective folding plates e-r-g, and their ends e-f-g are adhered to each other by self-adhesive force, as shown in Fig. 12.13. The article W (is sent in the transport direction, and at this time, the front end in the transport direction is folded and adhered onto the end h-1-j by the folding plate Q, and as shown in Fig. 14.15, the article W is In this packaging section 2, the product is wrapped with a film F.

In the case of the other packaging process shown in Figure 16.17,
First, in the same way as described above, the film F is unwound and sandwiched between a pair of feed rolls 1 and sent to the packaging section 2, and at the same time, a label d is attached by the label attaching mechanism in the previous step of this packaging section 2, and then) , gradually roll up the frame F into a cylindrical shape, put the article W into the rolled-up, fold the front and rear ends e-k over the left and right ends f-g, and stick them together. are packaged with film F in this packaging section 2.

In addition, depending on the contents of the article W as well as the upper surface of the article W wrapped with the film F, for example, JP-A-61-1
As is known from Japanese Patent No. 04937, the label d is also attached to the bottom or side surface of the article W.

[Problem to be solved by the invention]

However, the above-mentioned Japanese Unexamined Patent Publication No. 61-104937, Japanese Utility Model Application No. 62-62606, and Japanese Utility Model Application No. 62-19909
In the conventional structure known from the above publication, when the label d is attached to the film F, if it is attached to the bottom side of the article W, that is, the bottom position that becomes the ground surface of the article W, for example, in a supermarket, etc. When items W are displayed in the lower case of a refrigerator, the frost and moisture inside the case will come into direct contact with the label d attached to the bottom, causing the characters printed on the label d to become damaged. This has the disadvantage that the label d may bleed or disappear, and the label d itself may be damaged.

[Means to solve the problem]

The present invention aims to solve these inconveniences, and the gist of the present invention is to provide a packaging machine in which an article is wrapped with a film in a packaging section and a label is attached by a label attaching mechanism. A labeling device for a packaging machine is provided, characterized in that the labeling device is arranged at a position where the label can be pasted on the end portion of the film where at least the final folded end portion is folded.

[Effect]

At least the last folded edge of the film will be folded over the label affixed to the edge of the film, so that the folded edge will protect the label.
