Definitions
- the present invention relates to a device for cancellation of marks on thermosensitive material, in particular from deposit labels to disposable packaging such as beverage cans and plastic bottles.
- a deposit will also be levied on single-use packaging. It is intended to dispose of the disposable packaging already at the Manufacturing with a mark to provide the information about contains the deposit of the corresponding container.
- the Marking is carried out as a barcode or as a two-dimensional code, that on a label made of thermosensitive material is applied.
- a proposal to solve this problem provides that Depreciation mark by means of a laser beam by the thermosensitive material due to the laser beam introduced energy is blackened.
- the laser radiation used is dangerous to the human eye, so special security measures must be taken. These exist especially in that the laser beam as well as reflections and scattering of the same from the human eye have to.
- the object of the present invention is that of the prior art Technology described disadvantages to remedy.
- Halogen spotlights and focusing mirrors of the invention Devices are much cheaper than a laser Contraption.
- the halogen spotlight heats up the surface sufficiently of the thermosensitive material, so that this blackened, so the marking is canceled.
- the rays of light of the halogen spotlights are not harmful to the eyes, so that a foreclosure required when using a laser the radiation source can be omitted.
- the halogen spotlight executed rod-shaped, and it lies in an essentially parallel plane to the marking on the disposable packaging. Due to the length of the radiation source the marking can cover essentially its entire area be devalued because the focus of this radiation source is a line that travels over the mark. When using Such a flat devaluation of the marking could occur only with the help of an appropriate deflection device for the laser beam can be reached, which further increases the cost of the device.
- the device shown in the drawing can stand alone Furnishings manufactured or in an empties return machine be integrated. It consists of a rod-shaped Halogen spotlight 1, over which an approximately semi-cylindrical at a distance Focusing mirror 2 is arranged. Below Halogen spotlight 1 and focusing mirror 2 is a conveyor belt 3 arranged, which deposited disposable packaging, in this Example of a beverage can 4, based on the drawing, of promotes left to right, as indicated by an arrow 5 is. On the beverage can 4 is a deposit label 6 made of thermal paper applied, which one the deposit of the beverage can 4th has the corresponding barcode 7.
- the focusing mirror 2 focuses the light rays 8 of the Halogen spotlight 1 on the deposit label 6, so that on this depicts a focus 9. Since the hologram emitter 1 is rod-shaped, the focus 9 is linear.
- the halogen lamp 1 is across, in 45 ° to the conveying direction 5 of the beverage can 4, whereby the focus line 9 runs across the deposit label 6, as shown in Fig. 2. Because of the relative movement the focus line moves between the beverage can 4 and the halogen spotlight 1 9 on the deposit label 6 and blackens it.
- the barcode 7 becomes essentially unusable over its entire area, the inclination of the focus line 9 for a complete blackening ensures.
- the beverage cans 4 or other depositable one-way packaging such as.
- Plastic bottles are added to the conveyor belt 3 always fed in such a way that the deposit label 6 goes up, that is to say Halogen spotlight 1 indicates.
- To this location of the disposable packaging to achieve is a corresponding in front of the conveyor belt 3 Handling device arranged that the disposable packaging in connection with an optical recognition device rotates accordingly.
- Such handling devices belong to the state of the art and are therefore not described here explained.
- guides 10 are provided on each side, between which the disposable packaging on the conveyor belt 3 run through.
- Shutter 11 Between the conveyor belt 3 and the halogen lamp 1 is one Shutter 11 provided that closes when none Disposable packaging runs under the halogen lamp 1. There this shutter 11 is not in the focus area of the light rays 8 is located, their heating is not problematic. The The shutter 11 can be omitted if the halogen spotlight 1 is not constantly switched on, but only with one continuous disposable packaging is turned on. The Control of the shutter 11 or the switch for the halogen spotlight 1 can be done via a light barrier.
- the focus 9 of the halogen spotlight 1 is changeable. This is achieved in that the distance of the focusing mirror 2 adjustable by the halogen lamp 1 is, as indicated by an arrow 12. Controlling the distance of the focusing mirror 2 can be optical via signals Distance measurement take place with the distance of the deposit label 6 is measured by the halogen spotlight 1.
