Definitions
- the invention relates to a method and a device for producing deactivatable security elements for electronic article security, wherein a security element made of a soft magnetic strip of a predetermined length, which is excited to emit a characteristic signal when an alternating magnetic field is applied, and sections of a defined length of a semi-hard or consists of hard magnetic material, the sections with respect to the soft magnetic strip being arranged in such a way that, when saturated, they prevent the characteristic signal of the soft magnetic strip.
- a monitoring system has a transmitting and a receiving device.
- the transmitting device sends an interrogation signal into a monitoring zone.
- the stripe element is excited to emit a response signal which is generated by the
- Receiving device is detected and identified.
- the occurrence of a response signal is in fact equated with the illegal passage of an electronically secured article through the interrogation zone, and the alarm is triggered.
- An example of a corresponding monitoring system is described in EP 0 123 586 AI.
- the strip elements are designed to be deactivated. Deactivation is achieved in that, with respect to the soft magnetic strip, sections of a semi-hard or hard magnetic material are arranged which prevent a reaction of the securing element to the interrogation signal as soon as the semi-hard or hard magnetic material is driven into saturation by applying a correspondingly high magnetic field has been.
- the invention is based on the object of proposing a method and a device which make it possible to produce the deactivatable strip elements at low cost.
- the object is achieved in that an endless strip made of semi-hard or hard magnetic material is provided and divided into the individual sections of defined length, that the sections of defined length are passed on by means of a conveyor device whose speed is greater than the speed at which the endless strip is provided, the relative speed being so is dimensioned that a desired distance between two successive sections is achieved, and that a soft magnetic endless strip is connected to the spaced sections of semi-hard or hard magnetic material.
- a significant improvement of the method according to the invention is that it enables continuous production of security elements that can be deactivated.
- a composite material is applied to the spaced apart sections of semi-hard or hard magnetic material and that the soft magnetic endless strip is applied to the opposite side of the semi-hard or hard magnetic sections.
- the soft magnetic endless strip it is also possible for the soft magnetic endless strip to be connected directly to the sections made of semi-hard or hard magnetic material.
- an embodiment with regard to the method according to the invention suggests that the strip material produced is wound up.
- the strip material with the deactivatable securing strips is divided into individual sections carrying the securing elements.
- a supply roll is provided, from which a semi-hard or hard magnetic endless strip is unwound
- a cutting station is provided which divides the semi-hard or hard magnetic endless strip into individual sections of a predetermined length that a Conveyor is provided which has a higher speed than the speed at which the semi-hard or hard magnetic endless strip is provided, so that the successive Sections of semi-hard or hard magnetic material have the desired distance from each other, and that a supply roll is provided, from which a soft magnetic endless strip is unwound, which is connected to the semi-hard or hard magnetic sections (tape material).
- the conveyor device is a conveyor belt, with respect to which a vacuum source is arranged such that the individual sections made of semi-hard or hard magnetic material are fixed on the conveyor belt at the desired distance from one another.
- the conveyor device is a conveyor belt, with respect to which at least one magnet is arranged in such a way that the individual sections of semi-hard or hard magnetic material open at the desired distance from one another fixed on the conveyor belt.
- the finished strip material consisting of coherent strip elements that can be deactivated, is then wound onto a storage roll.
- Fig. 1 shows a longitudinal section through an advantageous embodiment of the device according to the invention.
- the endless strip 4 made of semi-hard or hard magnetic material is unwound from a supply roll 5 and divided into sections 3 of a desired length in the cutting station 6.
- the sections 3 are then taken over by the conveyor belt of the conveyor device 7 and transported further in the machine running direction.
- the conveyor device 7 is a conveyor belt with air holes.
- a vacuum source 8 is arranged, which fixes the individual sections 3 of the semi-hard or hard magnetic material at a desired position of the running conveyor belt.
- the conveyor belt of the conveyor device 13 has a higher speed than the rotating cutting cylinders of the cutting station 6, the individual sections 3 made of semi-hard or hard magnetic material on the conveyor belt are at a certain distance from one another. The distance itself can be set as desired via the relative speed between the cutting station 6 and the conveyor device 13.
- a composite material 16 is glued to the spaced-apart sections 3.
- the sections 3 connected to one another via the composite material 16 are then glued in the coating or laminating station 12 with a soft magnetic endless strip 15.
- the soft magnetic endless strip 15 is unwound from the supply roll 11.
- the finished strip material 13 is then wound onto the storage roll 14.
- the strip material 13 consists of a soft magnetic endless strip 2, on which semi-hard or hard magnetic sections 3 are arranged at a desired distance from one another.
