Description

Information carrier as well as apparatus and method for

Attaching and removing such an information carrier

description

The invention relates to an information carrier for attachment to an object to be marked, wherein the information carrier has at least one contact surface which is in contact with the surface of the object to be marked by magnetic adhesion of the information carrier to the object to be marked, and a device and a

Method for attaching and removing the information carrier.

Such an information carrier is needed to tag objects or to provide information. The information should be reversibly removable from the object again in order to enable a multiple identification of the object. The storage of the information on the information carrier is conceivable in various variants. Thus, for example, the information may be stored optically, in the form of fonts, characters, color or bar codes, or also electronically in the form of RFID on the information carrier.

task

The invention has the object of providing an information carrier in such a way that the information carrier can be attached without human intervention by means of a simple mechanical device to an object, and can be removed by a simple mechanical device of this object. This object is achieved in that the information carrier has a carrier surface which is approximately parallel to the contact surface, in that the information carrier has a decontacting surface following the contact surface, which is inclined away from the surface of the object to be marked, and at an angle therewith a forms, and that the information carrier by means of a corresponding device on the surface of the object to be marked can be attached and removed from this.

Advantageous embodiments of the invention are given in the subclaims.

In the invention is an information carrier which is suitable for storing information and temporarily attached to an object. The information can be stored in various forms on the information carrier. So is a simple optical

Marking by color design of the information carrier conceivable. By labeling the information carrier with letters and numbers or other characters, a representation of information on the information carrier can also be done. Stored data in the form of barcodes on the information carrier are also conceivable.

In addition to the possibilities to store information for optical detection on an information carrier, there are also electronic options for storing information on an information carrier. In a preferred embodiment, the mounting of an RFID tag on or in the information carrier gives the possibility of contactless recording of stored data.

According to the invention, the attachment of the information carrier to the object to be marked by means of magnetic adhesion. For this it is necessary that the object to be marked at least partially consists of magnetizable material. By at least one magnet located in the information carrier results in a magnetic force action between the Information carrier and the object to be identified. A magnetic adhesion of the information carrier on the object to be marked is possible. In an expedient embodiment, the information carrier has a contact surface on which the information carrier can be made to touch a surface of the object to be marked in a touching manner. The magnet located in the information carrier causes a magnetic field at the contact surface of the information carrier, which allows a magnetic adhesion to the contact surface.

According to the invention, the information carrier has a further surface which is parallel to the contact surface and extends on the opposite side of the information carrier. As at the contact surface, there is also a magnetic field on the carrier surface, which is created by the magnet located in the information carrier.

In a specific embodiment, the magnetic field strength at the contact surface is greater than the magnetic field strength at the support surface. This difference in the magnetic field strength at the two surfaces can be generated by a corresponding positioning of the magnet in the information carrier. Thus, a positioning of the magnet is not conceivable on the center line between the two surfaces, but closer to the contact surface.

In an advantageous development, a plurality of magnets are integrated in the information carrier, wherein stronger or more magnets are arranged in the vicinity of the contact surface and weaker or fewer magnets in the vicinity of the carrier surface. As a result of this development, the different magnetic field strengths according to the invention are at the contact surface and

Carrier surface can be generated. According to the invention, the information carrier in addition to the contact surface and the support surface still has a Dekontaktierungsfläche. The decontacting surface adjoins the contact surface at an angle and runs towards the support surface. The magnets in the information carrier are to be arranged such that the magnetic field strength at the decontacting surface is lower than the magnetic field strength at the carrier surface.

For attachment and removal of the information carrier on an object to be marked, a device is provided by means of which a simple attachment and removal is made possible. The device has a carrier element which is designed such that the carrier surface of the information carrier can be contacted with the carrier element in a planar manner. In this case, the carrier element of the device is made of an at least partially magnetizable material, whereby the magnetic field on the support surface of the information carrier allows a magnetic attraction between the information carrier and the carrier element an adhesion.

In an embodiment of the invention, the carrier element is movably attached to the device. It is envisaged that the support element can be tilted, approximately at the angle that the Dekontaktierungsfläche the

Information carrier forms with the surface of the object to be marked, to which the information carrier adheres magnetically.

By means of the device attachment of the information carrier to an object to be marked is possible. Da2u adheres to the information carrier by a, resulting from the magnetic field on the support surface magnetic force with its support surface on the support member of the device. The device is moved with the adhering information carrier to the object to be marked until the contact surface of the Informationsträ- gers is in contact with the surface of the object to be marked.

The magnetic field at the contact surface of the information carrier causes a magnetic attraction between the information carrier and the surface of the object to be marked. Due to the magnetic Field strength differences at the carrier and the contact surface of the information carrier, the resulting magnetic force between the information carrier and the object is greater than the resulting magnetic force between the information carrier and the device. Upon movement of the device away from the object to be marked, the information carrier adheres to the object to be marked magnetically.

In a specific embodiment, the support element of the device consists of two different elements. The front, in direct contact with the support surface of the information carrier standing single element is formed as a plate and consists of a non-magnetizable material, such as plastic. The directly behind arranged second single element consists of a magnetizable material and is pivotally mounted away from the first single element. The first individual element is designed to be so thin that upon contacting the carrier surface of the information carrier with the first individual element, a magnetic interaction with the second individual element is not prevented.

In the affixing process of the information carrier to the object to be marked, the second individual element is pivoted away from the first individual element after contacting the carrier surface with the carrier element. Due to the resulting greater distance between the information carrier and the magnetizable individual element of the carrier element, the magnetic force between the information carrier and the carrier element is reduced. Thus, a removal of the device from the object to be marked is possible, wherein the information carrier magnetically remains on the surface of the object to be marked.

To remove the information carrier from the object to be marked, the carrier element is tilted on the device. It corresponds to the

Tilt angle approximately at the angle that forms the Dekontaktierungsfläche the contact surface, but in the opposite direction. The device with the tilted carrier element is then attached to the information carrier on characterizing object moves until the support member contacts the support surface of the information carrier in the region of the Dekontaktierungsfläche. By further approximation of the carrier element to the object to be marked causes the support member via a lever tilting the information carrier against the magnetic force on the contact surface, so that instead of the contact surface, the Dekontaktierungsfläche contacted the surface of the object to be marked. In the same process, the carrier surface of the information carrier contacts the carrier element. Due to the magnetic field strength differences at the decontacting and the carrier surface of the information carrier, the resulting magnetic force between the information carrier and the carrier element is greater than the resulting magnetic force between the information carrier and the object to be identified. Upon movement of the device away from the object to be marked, the information carrier adheres to the carrier element magnetically and can be removed from the object to be marked.

In a further embodiment, it may be provided to form the decontacting surface as a circular, elliptical or hyperbolic rounding connected to the contact surface. As a result, the carrier surface of the information carrier is removed when it is to be marked

Object instead of a tilting movement, brought by a rolling movement of the information carrier on the Dekontaktierungsfläche with the support element in contact. In an appropriate form of education, the information carrier is round

Disc formed, the front of the contact surface and back represents the support surface. The Dekontaktierungsfläche is formed as a circumferential chamfer on the contact surface. This embodiment is particularly advantageous because the orientation of the information carrier and thus the decon- taktungsfläche for attachment and removal of the characterizing

Object does not matter. Further expedient forms of embodiment of the information carrier represent polygons. In this case, the decontacting surface can be configured as a round circumferential chamfer so that the contact surface forms a circle, or the decontacting surface can be formed as individual chamfers on each segment of the polygon, so that the contact surface has a shape according to the polygon.

Further embodiments of the invention are described in the subclaims.

An embodiment of the invention is illustrated in the drawing and will be explained in more detail below. Show: ig. 1 an information carrier in a spatial view;

FIG. 1 shows an information carrier 1 in a spatial view. The formed as a disk information carrier has a contact surface 2, which is provided for contacting an object to be marked. In the contact surface 2, a magnet 5 is integrated. The magnet 5 causes an attraction between the information carrier and the object to be marked. A decontacting surface 4 adjoins the contact surface 2 circumferentially on the edge of the disc-shaped information carrier 1. This is provided for removing the information carrier 1 from an object to be marked.

FIG. 2 shows the information carrier 1 in a three-dimensional view, but from the side facing away from the contact surface 2. Evident is the back of the disc-shaped information carrier, which forms a support surface 3. The support surface 3 is provided for contacting the information carrier 1 on a support member 10 of a device for selectively attaching or removing the information carrier. In the support surface 3 here four magnets 6 are integrated, which allow a magnetic adhesion of the information carrier 1 to the support member 10.

In FIGS. 3a to 3d, the attachment process of an information carrier 1 to a surface 9 of an object 8 to be marked is shown. In each case, the object 8 to be marked is to be seen, wherein the object 8 consists at least partly of a magnetizable material, the information carrier 1, as well as the carrier element 10 of the device for selectively attaching or removing the information carrier. In Fig. 3a, in front of the surface 9, the support member 10 is shown, which is arranged on a device for attachment and removal of the information carrier. The carrier element 10 consists of a first single element 1 1, which consists of a non-magnetizable material and a second single element 12 which consists of a magnetizable material.

Adhering to the carrier element 10 by magnetic force of attraction on the second individual element 12 of the information carrier 1. The information carrier. 1 contacts the first individual element 11 of the carrier element 10 with the carrier surface 3. The contact surface 2 is arranged parallel to the surface 9 of the object 8 to be marked. A represents the direction of movement of the carrier element 10 with the information carrier 1 attached thereto.

3b illustrates the contacting of the contact surface 2 of the information carrier 1 with the surface 9 of the object 8 to be marked. The magnets integrated in the information carrier generate a magnetic force both on the carrier element 12 and on the object 8.

In FIG. 3c, B represents a folding movement of the second individual element 12 away from the first individual element 11. The resulting greater distance between the second individual element 12 and the information carrier 1 reduces the magnetic attraction between the information carrier 1 and the information carrier 1 Carrier element 10.

The movement C of the carrier element 10 away from the object 8 to be marked is shown in FIG. 3d. In this case, the information carrier 1 remains on the surface 9, since the magnetic attraction between the information carrier 1 and the object 8 to be marked is greater than the force of attraction between the information carrier 1 and the folded-away second individual element 12.

FIGS. 4a to 4c illustrate the removal process of an information carrier 1 from the surface 9 of the object 8 to be marked. The object 8 to be identified, the information carrier 1, and the carrier element 10 of the device for selectively attaching or removing the information carrier, are shown in each case , In Fig. 4a, the information carrier 1 with the contact surface 2 adheres to the

Surface 9 of the object to be marked 8 magnetically. On the side of the support surface 3 of the information carrier 1, the support element 10 is moved in the direction A 'up to the information carrier 1 zoom. The carrier The element 0 was inclined by the angle ', the angle a' corresponding approximately to the angle which the decontacting surface 4 forms with the surface 9 of the object 8 to be marked, but in the opposite direction.

As a result of further movement B 'of the carrier element 0 in the direction of the information carrier 1, the carrier element 10 exerts a force on the carrier surface 3 in the region of the decontacting surface 4. The resulting leverage on the information carrier 1 acts around the edge, which form the contact surface 2 and the Dekontaktierungsfläche 4 together. The leverage causes a tilting movement C of the information carrier 1 about the said edge, so that the angles are α and smaller. The movement B 'of the carrier element is continued until the decontacting surface 4 is in contact with the surface 9 of the object 8 to be marked and the carrier surface 3 is in contact with the carrier element 10.

According to the invention, the magnetic attraction due to the magnetic field strength differences on the support surface 3 between the information carrier 1 and the support member 10 is greater than the magnetic attraction on the Dekontaktierungsfläche 4 between the information carrier 1 and the object to be marked. 8

The movement D 'of the support member 10 away from the object 8 to be marked is shown in Fig. 4c. In this case, the information carrier 1 remains magnetically adhering to the carrier element 10 and is thus removed from the surface 9 of the object 8 to be marked. LIST OF REFERENCE NUMBERS
