Abstract

The invention relates to an edge strip roller. The aim of the invention is to simplify storage for customers who use the edge strip roller and who want to offer a plurality of different edge strips. Said aim is achieved by virtue of the fact that said edge strip roller has at least two different edge strips.

Description

Edge tape roll

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 edgebanding sector 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 has to build up considerable stock for the variants, which are then brought together on so-called commissi- on 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 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. If an order is submitted by a customer (eg furniture manufacturer) in which the parameters of different edge strips (type, length, quantity) are defined, these are produced by the edge band hersteller in appropriate order, integrated into at least one edge band roll and the customer for further Processing provided. 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 may be advantageous 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 encompass the entire visual and aesthetic appearance of an edge band which is influenced, in particular, by imaging, coloring, patterning, embossing, painting, gloss, etc. By assembling edge bands with different patterns on an edge band roll Even if the edge bands differ only with regard to the decoration, the edge band roll according to the invention can already comprise an enormous variety of different edge band variants.

The term "geometry" is intended to encompass the entire external 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 For example, edge bands with different widths and / or thicknesses can also be integrated in an edgeband roll, which Modere edge banding machines require little or no set-up time to process edge bands of different widths and / or thicknesses despite the increased variety of products, reduce its stock levels even further The term "material" should not only include the material itself, but also all material properties. With the solution according to the invention, the customer can nimal stocks also offer or process edgebandings made of different materials in order to meet the trend towards a greater variety of products. The preceding considerations apply analogously to edgebands which differ in at least one of the features consistency, surface property or layer structure, or in any other feature which, according to the conventional solution, requires stocking of its own edge band roll.

It may prove helpful if 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 continuous roll, the need of one or more customers for edgeband rolls with different properties, for example decoration, consistency, surface property or layer structure, can advantageously be made available 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, by the edgeband roll according to the invention also an online production is possible, which is adapted to the exact types of needs or requirements of customers, produced.

However, it is also within the scope of the invention that the edge band roll according to the invention 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 known per se methods of digital printing, so that the Edge band roll in accordance with the invention has two different edge bands, which differ with respect to the decor. This advantageous embodiment can be produced for the first time by an endless roll any edge strip in a variety of decors, textures, surface properties or layer structure, 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 actual decor visually appealing visible, but protected, providing. It can be helpful if the edge bands are connected in chains. As a result, the edge bands can be processed more easily in the intended order at the customer.

It can also prove to be practical if the edge bands are arranged lying one behind the other in the longitudinal direction. Although the edge bands can also be arranged lying side by side or one above the other in the longitudinal direction; However, the variant is preferred in which the edge strips in the longitudinal direction one behind the other, ie shock-to-joint, are arranged, as this variant 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 may also be beneficial 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 may prove advantageous if the edge bands are arranged overlapping. As a result, the adjacent edge bands can be held together in a force-locking and adhesive-free manner.

It may prove useful if the edge bands are connected via a connecting means. As a result, the straps can be connected and disconnected with particularly little effort. Preferably, the bonding means is designed as a weak point such that it fails, particularly breaks, dissolves, or peels off at least one edge band when exposed to conditions (e.g., heat, moisture, etc.) against which the edge bands themselves are resistant. Suitable connecting means are in particular films, Velcro strips, edge band pieces, other material strips, etc., which are connected for example by gluing, welding, riveting, etc. with at least one of the edge bands to be joined.

It may also be helpful if an edge band is formed integrally with at least one connecting means. As a result, a separate connection means is unnecessary and the number of joints is reduced significantly. It may also be practical if an edge band is positively connected to a connecting means or 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 one another via positive connections with, for example, dovetail-shaped punched-out portions. The engaging in the punching connection means is preferably formed integrally with the adjacent edge band. Alternatively, the connecting means is a separate component which is positively connected with two adjacent edge bands.

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

It may also be advantageous if an edge band is non-positively connected to a connecting means or 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 detached from one another simply and without separate aids.

It can prove to be helpful 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, for example, 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 barcode, magnetic strip or an RFID chip applied in or at the joint joint of the different edge bands. 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. Electronic, magnetic or optically readable information 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 may be 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.

But it may also be advantageous if the information carrier is attached to a connecting means. Alternatively, the information carrier is even formed as a connecting means or vice versa. As a result, the information carrier can be easily removed after the read-out of the provided information so that no traces remain on the edge bands to be processed.

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 may prove convenient if the device has a reader to read 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 strip roll with the inventive device considerably easier. 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 takes place automatically during the passage of the edge band to be processed.

It may prove useful if the device comprises a reader to read information provided by an information carrier and read electronically, magnetically, optically and / or mechanically readable.

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

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 connected directly to one another and / or via connecting means 3. A connecting means 3 is preferably a separate element which is connected to the edge bands 2 to be connected, or the connecting means 3 is formed integrally with at least one of the edge bands 2 to be connected.

Each edge band / edge band connection or edge band / connection means connection can be designed positively, non-positively and / or materially, depending on which 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 or edge band 2 and connecting means 3 in the edge band / connection means connection, positively into one another. For example, two edge bands 2 are riveted, wherein the rivet represents the connecting means 3. In the cohesive connection the connection partners are adhesively and / or cohesively connected, in particular welded, glued or fused.

In the frictional 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. The connecting means 3 is preferably designed as a "predetermined breaking point" which is to fail if the connection point is exposed to conditions which are soft compared to the edge bands 2. A connection means 3 designed as a "predetermined breaking point" can be obtained, for example, by brief exposure to hot air, microwaves, radiation , etc. or the like are heated in such a way that the connecting means 3 dissolves, is detached or destroyed. Suitable connecting means 3 are, in particular, films, Velcro tapes, edge band pieces, or other strips of material, etc., which, for example, can be glued, adhesively bonded or adhesively bonded. Welding, riveting, etc. are connected to at least one of the edge bands 2 to be connected.

In order to facilitate the further processing of the edge band roll 1 at the customer, each edge band roll 1 can optionally have 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 exemplary embodiment of the edge band roll 1 according to the invention. The edge bands 2 abut one another in a butt joint and are welded together in a materially bonded manner, 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 band roll 1 according to the invention of the second exemplary embodiment in the stretched state. An edge band 2 is formed integrally 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 is moved perpendicular to the surface of the adjacent edge band 2, ie in FIG. 2 perpendicular to the sheet plane, which is usually only possible in the stretched state. When rolled up, the edge bands 2 are held together in a captive manner. The areas and canals Th, in particular the surfaces and visible edges, 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.

3 shows a schematic side view of a third exemplary embodiment of the edge band roll 1 according to the invention. The edge bands 2 are arranged in an overlapping manner and are non-positively connected with one another in the rolled-up state. In the rolled-up state, the overlapping regions of the adjacent edge bands 2 are pressed against one another and held together, as shown clearly in FIG. 3. 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.

4 shows a side view of a connecting region of two edge bands 2 of the edge band roll 1 according to the invention 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.

5 shows a schematic view of a device 5 for producing the edgebanding roller 1 according to the invention. The device 5 comprises a roller magazine 51, a roller take-off 52 with measuring wheel, a length measuring device 53, a packaging device 54 with first and second punching, a connecting device 55 and a trained as a double winder winding device 56th

The roller take-off 52, the length measuring device 53 and the packaging device 54 are arranged, for example, on a base frame 57. The roll magazine 51 comprises a multiplicity of different edge strip rolls, each consisting of one edge strip. The edge bands of the different edge band Rolls differ in at least one of the features: decor, geometry, material, texture, surface property, or layer structure.

The role deduction 52 with measuring wheel takes order according to an order from a customer, successively different edge bands from the roll magazine 51. In the length measuring device 53, the edge bands are measured to order and cut to length.

In the packaging device 54, the edge bands are processed such that two adjacent edge bands are connectable. In accordance with FIG. 2, an end-side section of the edge band located in the conveying direction is punched out in the first punch of the packaging device 54. According to FIG. 2, a connecting means is punched out in the second punch of the packaging device 54 at the end-side section of the edge band located in the conveying direction, which fits exactly into the punched-out edge band in the conveying direction. In the connecting device 55, the adjacent edge bands are brought together and connected. In addition, an information carrier is attached to each edge band. The information carrier provides information about the type and length of the edge band ready to trigger a corresponding operation during the passage of the edge band by a Kantenanleimanlage. The entire device 5 for producing the edge band roll 1 according to the invention is controlled by a control device. With the solution according to the invention it is possible for the first time to build a just-in-time production in the production of furniture panels, for example, in addition to the reduced storage edgeband rolls in which varied edge bands varies according to at least one of the features: decor, geometry, material, consistency , Surface property or layer structure, after their geometric dimensions (widths or thicknesses), for example, according to different materials such as PVC, PP, PMMA or ABS, foamed edges and differently decorated edge bands can be provided inexpensively available.
