Apparatus for packaging paper handkerchiefs or the like in cases with a label

The invention relates to a device for wrapping products 5 in a sheet of flexible material, on the other surface of which a name tag is affixed to the outside.

The invention can be applied in particular to handkerchiefs made of cellulose wadding, which are bent into a bellows structure and packed in a parallelepiped-shaped housing of plastic material or paper 10.

In order to keep the handkerchiefs clean after opening the package, a flap suitably cut into the package is already arranged in a known manner in the opening in the package from which the handkerchiefs are introduced.

15 This opening is delimited by a torn line which is torn open when the first handkerchief is to be removed from the package. The shape of this line, which is, for example, a circular arc with a cutting start zone, thus makes it possible to partially detach one surface 20 of the packaging box by bending it about an axis formed by a line passing through the ends of the cut.

The adhesive flap, which is firmly connected at one end to the opening, acts as a removable strip and keeps the opening closed when handkerchiefs are not needed. The end of the adhesive flap opposite the flap cut into the package 25 may have a non-adhesive surface portion that facilitates gripping of the flap and allows the package to be reopened.

The devices known to the author of this patent application have a device for transporting and attaching the name tags, which is located below the position where the handkerchief bundles are packed in the case intended for them.

The affixing of the labels thus takes place in the final stage of manufacture. This sequence of the various stages of manufacturing the housings, which was initially very simple, now necessitates the connection of a bulky and overly complicated nameplate attachment to the end of the machine. Each housing must therefore be precisely positioned by mechanical means in relation to the transport part 5 of the labels. If it is desired to place the label on a surface which is not the upper surface of the housing when the housings leave their manufacturing station, a turning and positioning mechanism must be added to the device. In addition, due to the soft backing of the labels - the paper towel package - a highly tacky adhesive must be used in order to minimize compression on the package at the time of transfer and to eliminate the risk of product damage and misalignment. Manufacturing costs increase as a result.

15 These problems can be eliminated by changing the order in which certain operations are performed, specifically by affixing a label to the package sheet before wrapping the nose-cloth bundle in it. The labels are preferably placed at regular intervals on a strip of packaging material, after which the sheets are cut apart and formed into cases.

Apparatus according to the invention for packaging paper handkerchiefs or the like in cases having an adhesive-labeled label, the apparatus comprising means for feeding a strip of flexible material, means for forming intermittent cutting lines at regular intervals in this strip, means for feeding the adhesive-treated strip on one side and in the form of labels on a strip of spring-like material and means for packing paper handkerchiefs, the label being located outside the package, is thus characterized in that the cutting lines are arranged so that each delimits a flap whose fold axis defines the ends of the cutting line 35, and that the device also comprises a cutting and transfer device comprising a cutting member adapted for a rotating cylinder cooperating with a cylindrical transfer member having an axis is arranged perpendicular to the direction of travel of the strip, whereby this device 5 transversely cuts the adhesive strip on one side into individual labels and transfers the labels to the strip of flexible material in the area of the cutting lines.

Due to this arrangement, the label is not attached to the now soft product, but a rigid support is provided on the packaging sheet relative to the attachment part. This results in greater reliability and better accuracy. Normal glue can be used, as low tack is sufficient.

The location of the name tag can be chosen much more freely. 15 The sheet forming the packaging material of the product is then in the form of a uniformly applied, continuous strip. Since the strip moves relative to the fastening part, it is sufficient to perform a simple adjustment of the corresponding transfer parameters.

In the case of a paper napkin case-20 in particular, the flap of which is formed by a certain part of the packaging case, which is preferably pre-cut, a perforation line is made in the strip of flexible material before it is made into cases. Thus, the pre-cuts are also lines of weakness that are elastic under the influence of the various stresses applied to the elastic band as it passes through the machine. As the labels intersect with the perforation lines, the risk of the tape tearing and also breaking is considerably lower. This advantage is, of course, obtained only when the perforation lines are placed immediately below the place where the pre-cuts are made.

This arrangement of parts also allows the flap to be cut continuously.

According to a preferred structure of the invention, the transfer device is formed by a rotating cylinder, the axis of rotation of which is perpendicular to the direction of pulling of the strip and which 4 85128 contacts the strip without sliding with it.

The following description relates to a structural aspect of the invention, which, however, does not limit the invention.

Figure 1 is a simplified diagram of a production line.

Figure 2 shows in detail the mounting position of the labels.

Figure 1 shows diagrammatically a packaging device for handkerchiefs made of cellulose wadding. These bundles of 8 or 10 10 handkerchiefs come from a station to the right of the arrows in the figure (not shown) in which the cellulosic wadding is processed, i.e. folded and cut, and where the handkerchiefs are stacked into bundles 2. The handkerchief bundle is moved to a position 4 by a belt conveyor 15. are shown symbolically only as a block and in which they are packed in a box. Sheets 3 are also fed to station 4 before the enclosures are made. At the outlet end of the device, the handkerchief packages 5 wrapped in sheets 3 are guided by a belt conveyor to another station, where they may be subjected to further handling or are arranged for transport.

In devices known to the author of this patent application, the label is affixed to the packages only when they leave station 4, which presents certain difficulties, 25 because it is a soft product.

This function can be performed more simply and very reliably by placing a label on the packaging film before making the cases.

Figure 2 shows station 6 in more detail if this function takes place.

A strip of plastic material, for example polyethylene, or a strip of paper is fed from a roll which rotates on a shaft 10. The strip is held tensioned by a pendulum arm 12 as it winds out of the roll at a linear speed VI.

Ji 5 85128

The strip is guided by different guide cylinders up to the flap pre-cutting device 14. The device 14 comprises two cylinders 15, 16 rotating in parallel axes. The second cylinder 15 comprises a cutting blade 17 if there are curves forming a broken cutting line, the shape of which corresponds to the desired pre-cutting shape. Pre-cutting is performed on the strip by the blade 17 in the compression gap between said cylinders 15, 16.

On the other hand, a roll containing an adhesive plastic or paper strip 21 rotates on a shaft 22. The strip 21 moves forward at a linear speed less than the speed VI by means of motor-driven cylinders 24 whose axes of rotation are parallel.

According to the invention, a cutting and transfer device 25 is arranged in front of the cylinders 24 with respect to the pulling direction of the strip 21 15. It comprises two cylinders 26, 28 which rotate in opposite directions in axes parallel to the cylinders 24. More specifically, the transfer cylinder 28 is positioned and rotates so that it 20 does not slide over the belt 11. Its linear velocity is VI.

The cylinder 26 rotates at a speed synchronized with the speed of the cylinders 24 driven by the engine, and has on its surface cutting blades 27 parallel to its base line and in 25 rotations contacting the surface of the adjacent cylinder 28. The cutting blades 27 work with the suction cylinder 28 and cut the nameplates from the strip fed between them. The surface of the cylinder 28 has holes communicating with the vacuum zone, and said surface holds the labels in place after they have been cut. It should be noted that the non-adhesive surface of the tape faces the cylinder 28.

The third cylinder 30, which rests on the first two cylinders 26 and 28 in the same vertical line and rotates in the opposite direction to the cylinder 28, comprises parts 31 which are anvils which contact 6 85128 with each rotation of the cylinder 28.

In the support zone of the two cylinders (28, 30), the connection between the surface of the cylinder 28 and the vacuum is broken to facilitate the movement of the labels at the point when they arrive at this point, by a turntable (not shown) or some other internal device.

The strip from the pre-cutting device enters the gap between the cylinders 28 and 30, the labels are attached to it and it is guided by transport cylinders 33 to the housing manufacturing station 10.

In the example shown, the packing station comprises a large-diameter sheet 40 in which openings are made in the sheets 3, which are parallel to the axis of the sheet. The sheets are received by a device 42 which simultaneously cuts the tape and feeds the sheets into the openings. After the plate is rotated by a certain angle, the handkerchiefs are in turn fed to the locations of the sheets, where they are wrapped in the sheets. Although the operation of the device appears clear from the foregoing description, it will still be briefly described below.

The strip 11 is wound out of its feed roller and is guided to the device 14, where the blade 17 presses a perforation line 11a at regular intervals. The tension of the strip can be adjusted to suit with the pendulum lever 12 so that 25 folds or too loose points cannot be created.

The tape then enters the cylinders 26, 28, 30, where the labels are affixed to it as follows:

The belt 21 is guided at a speed V2 by means of rollers 24 in the direction of a transfer cylinder 28 rotating at a speed VI. The adhesive-free surface of the strip remains in sliding contact with the transfer cylinder 28 due to the pressure difference between the two sides of the cylinder wall. When the strip has moved a certain length, the cutting blade 27 enters the gap between the cylinders 35 26 and 28 and protrudes into the strip and cuts one label 11b therefrom. The label 11b then moves forward at a speed VI until it contacts and presses the tape 11 with its adhesive surface.

When the adhesive surface of the label contacts the film 11, the pressure on the opposite surface of the ni-5 label ceases so that the label can be transferred to the film. The rotation of the counter roll 30 is synchronized to correspond to the displacement movement of the nameplates, so that the anvils 31 act as a support surface.

It is the task of the installer to adjust the various elements to suit each other and to synchronize the rotational movements of the cylinders so that the nameplates are located at the desired position with respect to the pre-cut 11a, as shown in the figure.

The tape is then directed to station 42, where it is cut into separate sheets which are fed one by one into openings 41 where handkerchief bundles come on top of them. A casing is then formed around the bundle by folding the edges of the sheet in a suitable manner and sealing them.

The above description relates to the formation of excess flaps in paper towel cases. The same method can, of course, be applied whenever a particular product has to be wrapped in a sheet of flexible material, whether it is an adhesive flap forming a closure flap or a mere name tag.
