The projections are aligned above the indentations by engaging the insert plate with a recess in the die.

Description

Punching tool with braille text DESCRIPTION: 5

FIELD OF THE INVENTION

The invention relates to a punching tool comprising a punching form as well as a punching plate cooperating with it, which punching form is provided with punching knives for punching a mold from a plate and creases for arranging folding lines in the mold to be punched out, which punching plate is provided of a crease mold which cooperates with the ridges on the die form, and which crease die is provided with slots present opposite the ridges on the die form. The creasing mold can in this case be a separate component that is fixed on the blanking plate or the creasing mold and the blanking plate 15 can be a whole, in the latter case this is referred to as a blanking creasing plate.

State of the art.

Such a punching tool is generally known and is used, among other things, to punch plates provided with folding lines from cardboard plates from which boxes can be folded.

Boxes intended for packaging medicines should soon be provided with braille letters to enable blind people to read which medicines are in the box. For this purpose, the die form must be provided with 25 pits and the crease mold of studs cooperating with the pits and forming braille letters.

If different series of identical boxes but with different braille texts have to be made, a different stamp must be applied for each series of boxes to form the braille text. When the stamp is exchanged, the new stamp must be positioned and fixed with respect to the creasing mold. Changing and positioning the stamp is a time-consuming and therefore cost-increasing activity.

Summary of the invention.

It is an object of the invention to provide a punching tool of the type described in the preamble in which the adjustment for manufacturing equal boxes with a different braille text can be carried out simpler and faster. To this end, the punching tool according to the invention is characterized in that the punching form is provided with a braille mold which is provided with a matrix of pits, and that the punching tool comprises an insert plate which is provided with protruding studs which are present directly opposite the pits and which are in braille letters forming patterns are present, which insert is closely fitted in a recess present in the crease mold opposite the braille mold. To change over, it is now not necessary to position the insert, which acts as a punch, but simply remove the old insert from the recess and insert the new insert into the recess. Due to the close fit, the new insert takes the correct position.

Optionally, the insert plate can be dimensioned such that it becomes clamped in the recess, so that no additional operations are required for the fixation. This means that a lot of changeover time can be saved.

The braille mold is preferably a separate component that is releasably present in a recess present in the die form or on the die form. As a result, the braille molds, which is a relatively expensive component, can be used for various punching tools.

In order to prevent the insert plate from being inserted into the creasing mold in a wrong position, an embodiment of the punching tool according to the invention is characterized in that the recess in the creasing mold has an asymmetrical shape and the insert has a shape that is similar to it. insert plate can only be fitted in one position in the recess in the creasing mold.

Brief description of the drawings.

The invention will be explained in more detail below with reference to an exemplary embodiment of the punching tool according to the invention shown in the drawings. Hereby shows:

Detailed description of the drawings.

Figure 1 shows a die form 1 of an embodiment of the die tool according to the invention. The die-cutting form 1 is provided with die-cutting knives 3 which are fixed in slots in a plate 5. Compressible rubber strips 7 are located on either side of the blanking knives on the plate 5 which after stamping print the die-cut form and the plate from which the shape of the die-cutting knives is punched. The die form 1 is furthermore provided with grooves 9 for applying folding lines in a form to be punched out.

In the plate 5 of the die form there is a recess 11 in which a braille die 13 is placed for forming braille letters in the shape to be punched out. The braille mold 13 is provided with a matrix of pits 15. In Figure 2, the braille mold 13 is shown separately. The wells 15 are located in three rows of 9 blocks of 2x3 wells each.

Figure 3 shows a blanking plate 21 of the blanking tool according to the invention. The die-cutting knives 3 of the die form come into contact with this die plate 21 during die-cutting, whereby a shape is die-cut from a plate. On the blanking plate 21 there is a creasing die 23 which is provided with slots 25 which, during blanking, cooperate with the ridges 9 of the blank. In the creasing mold 23 there is a recess 27 in which an insert plate 29 is present.

The insert plate 29 is provided with a pattern of protruding studs 31 which form braille letters. These studs 31 work together with the pits 30 in the braille mold 13 during stamping and arrange the braille letters in the form to be punched out. Figure 4 shows the insert plate 29 separately.

To prevent the insert plate 29 from being inserted into the recess 27 in the creasing mold 23 in a wrong position, the recess 27 has an asymmetrical shape that is obtained by beveling one of the corners 33 and the insert 29 has a congruent one shape in which one of the corners 35 is cut.

As a result, the insert plate 29 can only be arranged in the recess 27 in one position.

Although in the foregoing the invention has been elucidated with reference to the drawings, it must be stated that the invention is by no means limited to the embodiment shown in the drawings. The invention also extends to all embodiments deviating from the embodiment shown in the drawings within the scope defined by the claims.
