Description

Applicator and Applizierverfahren for linerless labels

The invention relates to an applicator for linerless self-adhesive labels according to the preamble of claim 1 and a method for applying such labels on a product according to the preamble of claim 1. 2

For the hitherto commonly used in the practice of self-adhesive labels, a material web is usually first prepared, of which one side has an adhesive layer and the other side is printable by a printing device. This web is usually wound into a roll which facilitates handling of the self-adhesive material and their storage. In order to prevent that the individual layers of the wound into a roll web of material as a result of the adhesive layer adhere to each other, and to further prevent the self-adhesive material adheres in the printing unit of feed rollers, pressure rollers and the like., The self-adhesive material to which is side of the adhesive layer with a substrate sheet covered.

This carrier material web makes it necessary, however, that after the printing of a portion of self-adhesive material which will later form a single label and the carrier material web is removed from the adhesive layer to a product prior to the application of this section. For this purpose, the known devices for applying or applying self-adhesive labels on products to a feed arranged in the direction of the self-adhesive material after the printing unit release unit, which replaces the substrate sheet of the self-adhesive material.

The provision of a substrate sheet in addition to the above-mentioned increased amount of handling even with the further disadvantage that the roll formed from the self-adhesive material having a relatively large diameter, only a portion of this diameter is beneficially used for self-adhesive labels. The other part is occupied by the support material. Eventually increase the overall cost of materials as well as the manufacturing costs, as in the manufacture of a roll of a self-adhesive material the support material must be applied to the self-adhesive web of material through the support material.

Due to the above outlined disadvantages of the previously known in practice self-adhesive labels in the recent past linerless self-adhesive labels, which are also called linerless labels have been developed. The time allotted for this Label self-adhesive material has also in the wound in a roll state on no more substrate layer covering the adhesive layer of self-adhesive material. The use of such material makes it necessary, however, that the printable side of the sheet having such a property that the individual layers of the wound into a roll web of material from sticking together. Moreover, it is necessary to provided in the printing unit with the adhesive side components coming into contact with a coating which prevents adhesion of the adhesive side of these components of the printing unit. Solutions to the problems described above in connection with linerless self-adhesive labels are already in practice.

However, it is currently difficult to automatically apply the individual printed, separated from the self-adhesive material self-adhesive labels on a product, since it must be ensured in applying, that the self-adhesive label to adhere to any other component of a device but only to the product. Due to the adhesive side of the label that is permanently available as opposed to a substrate having labels, this has not been realized. Therefore, linerless self-adhesive labels are previously applied in practice by hand but this approach does not allow for fast production workflow.

From the US Patent 5,531, 853 is an applicator and a method Applizier- out for linerless self-adhesive labels of the type mentioned. Here, a separation unit, and means disposed in the feed direction of the self-adhesive web of material according to the separation unit application unit is provided. The application unit detects the self-adhesive label on its adhesive-free side and puts it on the product. Here, the self-adhesive label is first separated from the Mateπalbahn through the separation unit and then this separated self-adhesive label detected by the application unit Thus, the separated self-adhesive label does not fall to the ground before it has detected the application unit, are in this known apparatus or in this known method Blasdusen provided on a bottom blade of the separation unit. This Blasdusen blow the separated self-adhesive label against the application unit, which then detects this by means of a suction and holding this case, is a prerequisite that the Blasdusen blow the separated self-adhesive label to the same degree against the application unit. For example, if clogged a Biasduse or has a Biasduse a higher blowing pressure than the other, then the separated labels can shift in its position and possibly no longer be detectable by the application unit Moreover, in this known device several handling precedent - separation by the separation unit bubbles against the application unit through the blowing means and detecting by the application unit - necessary for a single self-adhesive label is detected by the Applizieieinheit

Moreover, seen from the US Patent 2,492,908 a further applicator and a Applizierverfahren forth, wherein a holding device is provided which is arranged below the Mateπalbahn Before the separation unit local separating an individual self-adhesive labels from the self-adhesive material, this will still be separated piece of the Mateπalbahn covered by the retainer After the separation process the separated and still present on this holder label is then ornamental head detected by the actual app and applied by it to the product here three handling precedent will find a variety of components before the self-adhesive labels detected by the application unit is Furthermore, this known device is or this known method unsuitable for linerless self-adhesive labels, since thereby the adhesive side of Mateπalbahn or a single label in contact with the Halteeinrichtun g passes.

Finally, an applicator is clear from the GB Patent 800.045, which is part of the Tenneinheit simultaneously. After severing the web the detached label falls down and is then pressed simultaneously through the application unit to the to be provided with the label product. Between the separation of the label from the web and it is applied to the product but the label is not covered by the application unit.

It is an object of the present invention to provide an apparatus and method for automatically applying and applying to provide of linerless self adhesive labels which permit easy and trouble-free handling of the individual self-adhesive label with a simple structure of the applicator.

The above object is achieved with respect to the applicator by the features of claim 1. Advantageous embodiments of these solutions can be found in the dependent claims 2 to 1. 1

By adjoining in the direction of self-adhesive material to the separation unit application unit is now possible that where no adhesive layer side having to be covered by the self-adhesive web of material separated and possibly already printed self-adhesive labels and so long to hold until the self-adhesive label applied to the product is. Since in this case the use of a manpower is no longer necessary, the application in a manner adapted to the production requirements can be done quickly continuous or discontinuous. A fault in the production process due to adhesion of the separated self-adhesive label to the hand of an operator and the like. Does not occur.

To ensure a trouble-free operation, it has proved to be advantageous if the application unit from a starting position, which is located for example above the self-adhesive material and in which the self-adhesive material can not be grasped by the application unit, in a sensing position, is detectable in the forming before the separation of the respective self-adhesive label a portion of the self-adhesive material, and from there is further reversibly movable in a Applizierstellung in which the separated self-adhesive label can be applied to a product. Engaging and holding the separated self-adhesive label can be done in different ways. It has proved to be advantageous if the application unit by means of a vacuum, the self-adhesive label on the adhesive layer having no side, ie, the printable surface is detected and until application keeps to a product.

Basically it is possible to keep the separated self-adhesive label only pointwise by means of a suction force. The application of the self-adhesive label but is facilitated if the application unit maintains the self-adhesive label in a planar form, that is, if the application unit has a holding surface for holding the separated self-adhesive label. Thus, while the self-adhesive label is not applied with folds and the like. On the product, it has further proved to be advantageous if the surface area of ​​the support surface, preferably at least equal to greater than the surface area of ​​the self-adhesive label.

In order to apply the signal detected by the application unit self-adhesive label on the product, it is necessary when either the product is moved to the self-adhesive label or the application unit with the self-adhesive label to the product. Fundamentally speaking, the most diverse movements can be performed. So it is for example conceivable that the application unit is reversibly pivotable about a substantially vertical axis from a detection position in which prior to the separation of the corresponding portion of the self-adhesive web of material is detected in a Applizierstellung in which the self-adhesive label on the product is applied. To this small a space as possible to take up, it has proved to be advantageous if the application unit is reversibly movable together with the detected self-adhesive label in approximately perpendicular to the surface area of ​​the self-adhesive material. Thereby a for example, the adherend products continuously or discontinuously zoom promotional conveyor be provided, above which the application unit is arranged. Once through the separation unit an optionally already printed and detected by the application unit self-adhesive label has been separated from the self-adhesive material, the application unit is in the standby for applying the self-adhesive label on the product. If the product is then placed under the application unit, the application unit may be vertical to the direction of self-adhesive material or approximately moved perpendicularly to the surface extension of the self-adhesive material. Here, it is also possible that the traversing movement of the application unit starts before the product is disposed entirely below the application unit. It is also possible that the movement sequences of the product or the application unit take place one after the other. Here, it is also to be noted that the control of movements can take place both through a program and take appropriate sensors such as light barriers.

The intended for separating a single self-adhesive label from the self-adhesive web of material separation unit to perform the separation process have its own drive. In addition to the increase caused thereby the manufacturing costs for such applicator, a separate drive for the separation unit requires a corresponding control that coordinates the movements of the separation unit and the application unit with each other. To the contrary, the separation unit can be driven by the application unit, as not only a drive unit is thereby saved, but also the time necessary for Kooridination the movement between these two units controller. Here, the separation process can be achieved in a simple manner in that the separating unit attached to the application unit and can be moved with this in approximately perpendicular to the self-adhesive material.

The separation unit itself can have various configurations again. Typically, a separation unit is formed by at least one outer cutter and at least one lower blade, one of which is movable, while the other is stationary. In a thus constructed separation unit, it has proved advantageous if the upper cutter is controllable by the application unit and / or driven. It is also possible that the upper knife is mounted directly or indirectly to the application unit and there in particular to the front in the advance direction of the self-adhesive material the end of the application unit. In this case, after the advancing movement of the self-adhesive material which can either continuously or batchwise, for example, lowered the application unit, wherein the upper blade, which is mounted in the manner of the application unit that participate in the transverse movement of the application unit in contact the self-adhesive web of material passes, according to which the application unit has grasped the self-adhesive web of material comes into contact with the self-adhesive material and cuts the self-adhesive material in cooperation with the lower knife. Since the application unit has already entered the portion of the material web located in the advancing direction of the self-adhesive material after the separating unit, the so-obtained, separated self-adhesive label is held by the application unit after performing the separation process. Upon further lowering the application unit, the self-adhesive label is then applied to the product.

To assist in the separation of a self-adhesive label from the self-adhesive material may further be provided that the applicator unit is at least approximately reversibly movable in the direction of advance of the self-adhesive material. This prevents that the self-adhesive label does not adhere to the separation unit and / or the self-adhesive material after the separation. If the application unit to the above-mentioned movement in the position it has in the case of a separation unit of an upper and a lower blade proved advantageous if the upper cutter is indeed be driven and / or controlled by the application unit, but not with the application unit itself is in contact.

The self-adhesive material may be provided either as a flat sheet or as a wound on a reel material.

Thus, the operation is not disturbed by adhering the adhesive side of the self-adhesive web of material, it has proved advantageous if the parts coming into contact with the adhesive side of the self-adhesive material components, at least the separation unit with one of the adhesive force of this adhesive side are provided resisting coating.

The above-mentioned object is achieved as regards the method by the features of claim 1. 2 Advantageous embodiments of this method of the invention can be found in the dependent claims 3 to 1 1 6. As for the method, there are the same advantages as have been explained above in connection with the device.

Further advantageous embodiments and an embodiment will be explained below with reference to the accompanying drawings.

In the single drawing figure is schematic a printing unit 10, which is arranged in the feed direction V of a non-illustrated self-adhesive material after the printing unit 10 separation unit 20 and a thereto to Vanschließende in the feed direction application unit 30 is provided. The printing unit 1 0 printed self-adhesive material in a known manner. The separation unit 20 is composed of an upper blade 22 and a lower blade 24. The upper blade 22 may be attached to the application unit 30 in a manner explained hereinafter yet. In contrast, the lower blade 24 is stationary, for example on the frame of the printing unit 10 is fixed. The surfaces of the upper blade 22, but in particular of the lower blade 24, which come into contact with the adhesive side of the self-adhesive material, have a coating to prevent adhesion of the self-adhesive material to the separating unit 20th Likewise, the outer cutter 22 can be driven by the application unit 30 and / or controlled, wherein the top blade 22 need not be attached to the application unit 30th In this case, the movement of the upper blade 22 by the movement of the application unit 30 is derived, but is not the upper blade 22 in direct contact with the application unit 30th

The application unit 30 consists of a holding element 32, which has a holding surface 34th The support surface 34 preferably has such a surface extension that it can hold a detached from the self-adhesive material by the separating unit 20 self-adhesive label, which is also not shown, in such a way that the edge of the holding surface 34 projects beyond the self-adhesive label. For holding the self-adhesive label, the application unit 30 is provided with a likewise not shown suction device for generating a vacuum. Thereby, the self-adhesive material extending below the application unit 30, is arranged downstream relative to the arrangement of the single drawing figure, to which no adhesive layer bearing side, ie the side with an optionally carried out by the printing unit 1 0 imprint, detected and the support surface 34 is held.

As further seen from the single drawing figure, the upper knife 22 may be attached to the front end in the feed direction V of the application unit 30 thereto. In this case, projecting the upper blade 22 via the supporting surface 34 protrudes downwards. This results in the separation of a Selbstklebetiketts of the self-adhesive web of material before the application unit 30 crosses the conveying path of the self-adhesive web of material. In the case in which the application unit 30 is at least approximately reversibly movable in the feed direction V of the self-adhesive material, to assist the separation process for the self-adhesive label from the self-adhesive material, may also be provided that the upper knife 22 going from the application unit 30 is driven and / or controlled, but is not directly attached to the application unit 30th As shown by the double arrow B in the single drawing figure, the application unit 30 is vertically reversibly movable in a direction towards the surface area of ​​the self-adhesive material. Here, the application unit 30 receives at least one three positions. The application unit 30 is movable from an inoperative position to a detection position in which the application unit 30 detects the holding member 32 located below the self-adhesive material. During the movement from the initial position to the capture position, the upper blade can already come into contact with the self-adhesive material. A cutting must not take place here, however. Is the division of the self-adhesive material to produce a single self-adhesive label already takes place in this position, so as to may further be provided that the application unit 30 is at least approximately reversibly movable in the feed direction V of the self-adhesive material, to assist in this separation process. In this case the upper blade 22 is then driven only by the application unit 30 and controlled, but is not in contact with the application unit 30. For the detection position, the retaining element 32 of the application unit 30 in a Applizierstellung is movable, in which the of the self-adhesive material web separated self-adhesive label can be applied to a below the application unit 30, based on the single drawing figure, befindliches product P. During the movement from the detecting position to the Applizierstellung thereby separating the self-adhesive label by means of the separation unit 20 can be effected by the self-adhesive material. Of course, it is also conceivable that the application unit 30 after separation of the self-adhesive label from the self-adhesive material and before reaching the Applizierstellung an intermediate position, which can be referred to as the retaining position, occupies.
