Definitions

• the invention relates to an application device for applying flat material segments, in particular labels, according to the preamble of claim 1 and a method for applying such flat material segments to a product according to the preamble of claim 12.
• a flat material web is usually first produced, one side of which has an adhesive layer and the other side of which can be printed by means of a printing unit.
• the self-adhesive flat material web is covered on the side of the adhesive layer with a backing material web.
• This self-adhesive flat material web is usually wound up into a roll, which facilitates the handling and storage of the self-adhesive flat material web.
• pre-punched self-adhesive labels have been applied by application devices and therefore have predetermined length and width dimensions, the maximum width of a label being predetermined by the width of the flat material web.
• Such pre-punched labels can be applied continuously without stopping the product to be labeled.
• the application device or labeling machine must be converted, which increases the downtime of the application device and thus increases the labeling costs per product.
• the self-adhesive flat material web has no carrier material web.
• Such a flat material web can be rolled up like an ordinary adhesive tape. This enables increased productivity through more efficient rolls and therefore shorter set-up times.
• Lineriess labels are particularly environmentally friendly because there is no waste of silicone-containing carrier material. Additional advantages include reduced storage, transport and waste disposal costs through up to 50% more label material.
• lineries labels are not pre-punched, but are continuously removed from a roll and cut to the required length. Labels of different lengths can advantageously be produced from the same flat material web.
• the labels which are obtained from a flat material web with a carrier material, not to pre-punch them, but to cut them off from the flat material web in accordance with the desired length.
• the separation process required to separate a flat material segment from a flat material web with or without a backing material for producing a label has a major disadvantage: the feed of the flat material web must be stopped each time to enable trouble-free separation. This means stopping or at least delaying the products to be labeled on the application device. The result is a lower product throughput. Such a stop-and-go operation therefore has a higher material wear and energy requirement.
• the application device has a buffer or a buffer unit between a separation unit for separating a flat material segment from the flat material web and an application unit for applying such a flat material segment as a label on a product.
• the buffer or buffer unit advantageously decouples the process of applying the labels to the products from the separation process, which takes up a finite amount of time. The cycle rate of the products to be labeled is therefore independent of the duration of the separation process for a label.
• the buffer or the buffer unit of the application device according to the invention can contain a changeable loop formed from the flat material web between the separation unit and the application unit before each separation. The length of this loop represents the flat material web section that can be removed from the buffer unit and has at least the length of the distance covered by the surface of a product to be labeled during the duration of the separation process of the flat material segment on the application unit.
• the formation of the loop in the buffer unit is achieved by controlling the feed speed of the flat material web in such a way that it runs at least temporarily between two separation processes at a higher feed speed than the speed of the products to be labeled that are guided past the application device.
• the buffer unit has a feed roller that is driven in a controlled manner and a pressure roller that is spaced apart in the feed direction of the flat material web.
• the feed roller can be arranged in the detachment unit and is used to feed the flat material segment at a predetermined speed at any time.
• the pressure roller is provided for pressing the flat material segments onto the surface of the product on the application unit. Both the feed roller and the pressure roller are arranged parallel to one another and to the plane spanned by the surface of the product. In this way, a dispensed label, advantageously aligned with the surface to be labeled, is dispensed by the application device. It is also possible to provide a controlled drive on the pressure roller.
• the application device can have a control unit which, among other things, controls the speed of the driven feed roller of the buffer unit, as explained above, so that between two separation processes the formation of the loop with the required length from the flat material web is guaranteed.
• a sensor can be provided on the detachment unit to detect the feed speeds of the flat material web on the detachment unit. hen that transmits the detected speed to the control unit.
• a sensor for detecting the speed of the products on the application unit can be provided on the application unit or the conveyor, which sensor transmits the speed to the control unit.
• the flat material web can consist both of a carrier material web on which a self-adhesive label material web is applied and also of a carrier material-free label web. In the version with a carrier material web, this is removed from the flat material web in front of the separation unit.

• the housing 11 surrounding the assemblies of the device 10 to be explained in more detail below is partially removed in FIGS. 1 and 2. Only the substantially vertically extending rear wall 11a and a support plate 11b attached to it are shown.
• the labels E are produced from a flat material web 20, which consists of a self-adhesive label web 22 and a carrier material web 24 attached to the adhesive side 22a.
• the flat material web 20 is equipped in the form of a supply roll RV in the device 10 by plugging the roll RV onto an axis A1 shown at the top right in FIG. 1 and projecting perpendicularly from the rear wall 1 1a. From the supply roll RV, the flat material web 20 is fed via horizontally oriented deflection rollers R1, R2, R3 to a detachment unit 30, which is not explained in more detail and in which the label web 22 is detached from the carrier material web 24 by peeling off at a dispensing edge.
• the “empty” carrier material web 24 is guided from the detachment unit 30 to a waste roll RA shown on the right in FIG. 1, which is placed on an axis A2 projecting perpendicularly from the rear wall 10a, and is wound up by the latter.
• the release unit 30 is followed in the conveying direction of the flat material web 22 by a printing unit 40, which is not explained in more detail and in which segments of the label web 22 can be printed with the desired information. This can be done, for example, using a known thermal transfer printing process. A segment of the label web 22 printed in this way is then fed to a separation unit 50.
• the detachment unit includes, among other things, a controlled driven feed roller 30a for the controlled advancement of the label web 22 in the direction of the severing unit 50 or an application unit 60 adjoining the severing unit 50 in the advancing direction and then fed without slippage from the controlled feed roller 30a, which is controlled by a control unit, not shown, via the separation unit 50 to the application unit 60 at a feed rate defined at any time.
• the application unit 60 essentially consists of a pressure roller 60a which is oriented horizontally to the plane defined by the product surface O to be labeled and which presses the label E onto the surface O of the product P.
• the suspension and guidance of the pressure roller 60a are not shown in detail.
• the free-running pressure roller 60a can be attached in a resilient manner, reversibly displaceable in the direction of the surface of the product P, so that a sufficient pressure force can be exerted at any time via the pressure roller 60a for the crease-free application of the label E.
• the free-running pressure roller 60a can additionally be provided with a sensor element in such a way that the speed of the products P to be labeled P can be detected. This would also enable faults such as a lack of the products P to be detected.
• Such a sensor system can of course also be provided independently of the pressure roller 60a.
• FIG. 2 shows the detail D of the application device 10 from FIG. 1 on a larger scale.
• the separating unit 50 adjoining the printing unit 40, the application unit 60 and a possible embodiment of a buffer unit 70 arranged therebetween can be seen.
• the buffer unit 70 consists of the controlled feed roller 30a and the pressure roller 60a, between which one from the label E to be applied variable loop 80 of the flat material web 22 can be formed as a buffer.
• the buffer unit 70 makes it possible to decouple the application process from the separation process of a label E. This is due to the targeted interaction of the controlled feed roller 30a and the pressure roller 60a of the buffer unit 70.
• the necessary coordination between the feed speed on the feed roller 30a and the conveying speed of the product (s) P is ensured by the control unit (not shown) already mentioned in the application device.

• the filling of the buffer unit 70 namely the formation of the loop 80, is achieved between two separation processes in the separation unit 50.
• the control unit can use sensors, which can be provided, for example, on the feed roller 30a, the pressure roller 60a and the conveyor device F, to determine the current speeds of the product or products (see ) P on the applicator 10 and the label web 22 on the separation unit 50.
