Description

The invention relates to an edge strip roll or an edge strip strand in the rolled up and transportable state.

Industrially organized, for example, furniture manufacturers have constantly increased the number of variants offered in the edgeband area in terms of decor and geometry in recent years. As a rule, these companies offer over 100 different variants. Since the end customer can freely combine all variants from a catalog, this requires a high degree of automation in production and a high level of flexibility. The furniture manufacturer must build up considerable stock for the variants, which are then brought together on so-called Commission roads. In practice, this leads to very complex magazine solutions at the edge banding machines. Since the existing solutions are often no longer sufficient, the edgeband rolls are also replaced and replaced several times in their respective magazine locations until they are completely consumed.

The publication DE-A-31 20 270 discloses an endless veneer strip, in particular a veneer edge band with a carrier, on which veneer is applied, wherein the veneer is applied in the form of strip pieces of constant length in the longitudinal direction of the band-shaped carrier. The carrier consists of paper, fleece, textile, plastic or thin metal foil. On this carrier are spaced veneer sheets or veneer strip pieces arranged in the longitudinal direction, each having an equal length. The final veneer edge bands are obtained by cutting the backing carrying the veneer longitudinally into strips. The prerequisite is that veneer strip pieces are applied to the support, which correspond in each case to the length or width dimension of workpieces. A mandatory requirement for the manual or automatic further processing of veneer strip pieces, however, is that they are fixed or arranged on the carrier. This results from the fact that veneer strip pieces generally have a small thickness of about 0.2 to 0.4 mm and are to be applied as individual cut pieces to, for example, end faces of furniture panels. The carrier is to be regarded as a mandatory requirement for collecting and arranging the veneer strip pieces. The endless veneer strip described must also be guided as a horizontal band to the veneer edge belt conveyors or to the sheathing machines, since the veneer strip pieces are not bendable and the endless veneer strip can not be manufactured or transported as a roll in the sense of an edge strip roll.

The invention is based on the object of simplifying the storage of companies that produce edgeband rolls or further processing and offer a variety of different edge bands.

To achieve this object, the edge strip roll is provided according to claim 1, which has according to the invention at least two different edge bands.

The edge band roll according to the invention comprises a defined length, which is composed of different partial lengths of different edge bands. Is a customer (eg furniture manufacturer) submitted an order in which the parameters of various Edge bands (type, length, quantity) are defined, they are produced by the edge band manufacturer in the appropriate order, integrated into at least one edge band roll and provided to the customer for further processing.

As a result, the already finished edgebandings are no longer stored by the customer, but by the edge band manufacturer. The customer only carries out the final assembly. This makes it possible, on the one hand to drastically reduce warehousing at the customer and on the other hand to reduce the area for the production of furniture panels by an enormous reduction of the individual magazines and ultimately to reduce the cost of the customer.

However, it is also within the scope of the invention that the finished edge bands are made available to the customer, which in turn performs a separation of the different edge bands on a single role itself, with the same advantages as described above.

Preferred embodiments of the invention are claimed in the subclaims.

It is according to the invention if the edge bands differ in at least one of the features: decor, geometry, material, consistency, surface property or layer structure.

The term "decor" is intended to include the entire visual and aesthetic appearance of an edge band, which is influenced in particular by an imaging, coloring, patterning, embossing, painting, gloss, etc. By assembling edgebands with different decors on an edgeband roll, the stocking at the customer can be considerably reduced compared to the conventional magazine solutions. Even if the edge bands differ only with regard to the decoration, the edge band roll according to the invention can already comprise a tremendous variety of different edge band variants.

The term "geometry" is intended to encompass the entire outer dimensions of an edge band, in particular length, width and thickness. By assembling edge bands with different geometry on an edge band roll, the customer's stocking can be further reduced compared to the conventional solution. Thus, for example, also edge bands with different width and / or thickness can be integrated in an edge band roll, which are then processed in order one after the other.

Modere edge banding machines require little or no setup time to process edge bands of different widths and / or thicknesses. In this way, the customer can reduce his stock even further, despite the increased variety of offers.

The term "material" is intended to include not only the material itself, but also all material properties. With the solution according to the invention, the customer can despite minimal Stocks also offer or process edgebands made of different materials in order to meet the trend towards greater variety of products.

The preceding considerations apply analogously to edgebandings, which differ in at least one of the characteristics of consistency, surface property or layer structure, or in any other feature which, according to the conventional solution, requires the stocking of a separate edgeband roll.

It is not according to the invention, when the edge band roll is formed substantially in one piece. For this purpose, the edge band roll comprises a one-piece substrate, which is produced in a uniform basic shade, for example in white. On this substrate different decors are successively applied in a conventional method of digital printing, according to the requirements of the customer. Thus, in the context of a so-called endless roll, the need of one or more customers for edgeband rolls with different properties, for example, decor, consistency, surface property or layer structure, can be provided within the framework of production. In this case, advantageously at the points where a decor is replaced by another subsequent decor, an information medium can be printed, for example a so-called barcode. Thus, the edgeband roll also makes online production possible, which can be adapted to the exact requirements types or requirements quantities of customers.

It is not according to the invention that the edge band roll has a transparent or translucent substrate which has on at least one side, advantageously the later back, different decorations which can be applied in the per se known method of digital printing, so that the edge band roll has two different edge bands that differ with regard to the decor. By this design, any edge band in a variety of designs, textures, surface properties or layer structure can be made of a continuous roll, which is multifunctional attachable to any geometry of furniture panels, for example, since the transparent or translucent basic structure after attachment to the narrow side of a furniture board the actual decor visually appealing, but protected, providing.

It is according to the invention, when the edge strips in the longitudinal direction one behind the other, ie shock-to-joint, are arranged, as this greatly facilitates the arrangement of the edge strip roll in a magazine of a conventional Kantenanleimanlage and the sequential processing of the edge strips in the intended order.

It is also advantageous if the edge bands are arranged lying face to face. If the edge band roll with the different edge bands is formed so that the various edge bands are flush and abutment against each other, the edge bands can take on a particularly compact form when rolled up.

It is also practical if an edge band is positively connected to an adjacent edge band. Thus, the edge strips can be held together in the rolled-up state of the edge strip roll captive. In a preferred variant, the opposing free ends of the adjacent edge bands are connected to each other via positive connections with, for example, dovetail-shaped cutouts.

It is advantageous if an edge band is connected in a material-locking manner to an adjacent edge band. The cohesive connection proves to be particularly strong. However, the cohesive connection can also be designed such that e.g. can be solved particularly easily by heat, which facilitates the separation process of the edge bands.

It is also advantageous if an edge band is positively connected to an adjacent edge band. As a result, the edge bands can be held together without adhesive. The non-positive connection exists only as long as a force acts, the two connection partners pressed against each other and holds together. When rolled up, the edge bands are clamped between adjacent layers of the edge band roll. When unrolling from the edge band roll, the edge bands are then easily detached from one another without separate aids.

It is according to the invention if the edge band roll has at least one information carrier which provides at least one information concerning the edge band roll. As a result, further processing of the edge band roll can be substantially facilitated. In particular, the information carrier can provide information which adjusts and actuates a device for processing an edge strip roll specifically to the respective edge band to be processed. It is particularly within the scope of the invention that information carriers are arranged at the junctions of adjacent edge bands, which "tell" an edge banding machine the next edge band.

The information carrier has, for example, the form of a glued or fixed fastening element, which triggers a mechanical actuation on the edgebanding machine, or the shape of a in or at the joint joint of the different edge bands applied barcodes, magnetic stripe or an RFID chip. Thus, in addition to the optimal storage and just-in-time production at the customer so-called "intelligent edge band roll" are provided.

In addition, it may be practical if the information carrier provides electronically, magnetically, optically and / or mechanically readable information. Information that is electronically, magnetically or optically readable can be read or recorded contactlessly by a reading device, so that damage to the edge bands by the reading device is prevented.

An RFID (Radio Frequency Identification) chip represents e.g. electronically / magnetically readable information ready. A barcode / barcode represents e.g. an optically readable information ready. A magnetic strip provides magnetically readable information. An elevation, depression, constriction or the like provides a mechanically readable information.

It is advantageous if the information carrier is attached to an edge band. As a result, the information provided by the information carrier can be assigned to the edge band particularly easily.

The invention also provides an apparatus for processing an edge band roll according to any one of the preceding claims. Thus, the edge band roll according to the invention can be processed particularly efficiently.

It is according to the invention when the device has a reading device to read an information provided by an information carrier.

The device is operated and controlled in response to the information read. As a result, the processing of the edge band roll with the device according to the invention can be substantially facilitated. In particular, the device can be adjusted specifically to the edge band to be processed in each case, wherein the adjustment of the device preferably automatically during the passage of the processed edge band.

It has proven to be useful if the device has a reading device to read information provided by an information carrier and that can be read electronically, magnetically, optically and / or mechanically.

It may be convenient if the device is an edge banding machine.

The preferred embodiments of the invention will be explained below with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The invention relates to an edge band roll 1, which has at least two different edge bands 2. The edge bands 2 differ in at least one of the features: decor, geometry, material, consistency, surface property or layer structure.

The edge bands 2 are connected in a chain and are arranged one behind the other in the longitudinal direction. The edge bands 2 of an edge band roll 1 are directly connected to each other.

Each edge band / edge band connection can be designed in a form-fitting, non-positive and / or material-locking manner, depending on which type of connection is desired for the preferred application. In the positive connection, the connection partners, i. Edge band 2 and edge band 2 in the edge band / edge band connection form fit into each other.

In the cohesive connection, the connection partners are adhesively and / or cohesively connected, in particular welded, glued or fused.

In the non-positive connection, the connection partners are held together by an acting force, in particular by the force exerted by two adjacent layers of an edge band roll 1 on the intermediate layer.

In order to facilitate further processing of the edge band roll 1 at the customer, each edge band roll 1 has at least one information carrier 4 which provides at least one information concerning the edge band roll 1. The information carrier 4 is designed as a magnetic strip, barcode / barcode, RFID chip, as a mechanical element or the like. To provide an electronically, magnetically, optically and / or mechanically readable information that can be read by a reader.

In accordance with this information, a Kantenanleimanlage can be set to each edge band to be processed 2 and operated accordingly. For example, the information carrier 4 provides information about the length or the end of the edge band 2 to be processed, and triggers a separator when sweeping the information carrier 4 with a scanning device, which separates the adjacent edge bands 2 at the joint.

Fig. 1 shows a schematic side view of a first embodiment of the edge strip roll according to the invention 1. The edge strips 2 are butt-to-butt to each other and are materially connected to each other, in particular welded at the joints. In the first exemplary embodiment, each edge band 2 has an information carrier 4, which is attached to an end-side section on the underside of the edge band 2. The surfaces and edges, in particular the surfaces and visible edges, of the adjacent edge bands 2 are aligned flush with one another.

Fig. 2 shows a plan view of a connecting region of two edge bands 2 of the edge strip roll 1 according to the invention of the second embodiment in the stretched state. An edge band 2 is integrally formed with a connecting means 3 in the form of a T-shaped extension at a free end of an edge band 2. It is shown how the connecting means 3 positively engages in a matching T-shaped punching of the adjacent edge strip 2, so that the adjacent edge strips 2 can not be separated from each other in tensile stress in the conveying direction.

The connection of the adjacent edge bands 2 is detachable when an edge band 2 perpendicular to the surface of the adjacent edge band 2, ie in Fig. 2 perpendicular to the plane, is moved, which is usually possible only in the stretched state. When rolled up, the edge bands 2 are held together captive. The surfaces and edges, in particular the surfaces and visible edges of the adjacent edge bands 2 are aligned flush with each other, if possible. An information carrier 4 is attached to an end portion of each edge band 2.

Fig. 3 shows a schematic side view of a non-inventive edge band roll 1. The edge bands 2 are arranged overlapping and are positively connected to each other in the rolled-up state. When rolled up, the overlapping areas of the adjacent edge bands 2 are pressed against each other and held together, as in FIG Fig. 3 is shown clearly. When unrolling the edge band roll 1, the edge bands 2 are then easily detached from one another without separate aids. An information carrier 4 is attached to the underside at an end portion of each edge band 2.

Fig. 4 shows a side view of a connecting portion of two edge bands 2 of a non-inventive edge band roll 1 in the stretched state, wherein the edge bands 2 are connected via a connecting means 3 and an information carrier 4 is attached to the connecting means 3.

The edge bands 2 are abutting each other. The connecting means 3 is designed as a plastic adhesive tape and extends over the joint. In addition, the edge bands 2 are glued to the joint with hot melt adhesive. The connection of the adjacent edge bands 2 can be solved by heating, without damaging the edge bands 2 in the process. The information carrier 4 is located exactly above the joint and indicates the end of an edge band 2 or the beginning of the next edge band 2.

The surfaces and edges, in particular the surfaces and visible edges of the adjacent edge bands 2 are aligned flush with each other, if possible.
