Definitions

  • the present invention relates to a punch for punching blister packs in a punching unit.
  • Such punches are used for example in the production of blister packs, especially in the pharmaceutical industry.
  • blister packs pods filled with tablets of a foil strip are first sealed with a cover foil. Subsequently, the sealed blister strip is separated in the so-called separation process into individual blister packs. This is usually done by a punching process.
  • the blister band with the sealed cups is conveyed between a die and a punch and punched by a movement of the punch into individual blister packs.
  • Blister production uses different materials, such as PVC or aluminum.
  • different punches are needed for the different materials to be punched.
  • For the production of PVC blister packs predominantly so-called reverse roof cuts are preferred, while predominantly so-called diagonal cuts are used for the production of aluminum blister packs.
  • a disadvantage of the latter forms of punches is that with larger aluminum blister packs, the punching device tend to tilt due to the eccentric load by the diagonal cut on the punch. The punch blocks and in the event of serious damage, the die and punch must be replaced, which can cause longer machine downtime.
  • the device comprises a punch that has a substantially rectangular shape with four edges and four corners.
  • the punch has a so-called inverted roof shape, in which the four corners are at the same height and the working surface is lowered from both edges in the direction of a center line.
  • two juxtaposed lower and two juxtaposed upper corners are formed, wherein the two upper corners are higher than the two lower corners. The two upper corners and the two lower corners are through an inclined surface extending from the upper corners to the lower corners, connected to each other.
  • the present invention has for its object to provide a punch, which avoids a tilting movement during the punching process and is suitable for the production of aluminum and PVC blister packs.
  • the punch for punching blister packs in a punching unit has a working surface with a substantially rectangular shape.
  • the work surface includes four edges and four corners, with two upper corners higher than two lower corners.
  • the upper corners are diagonally opposite, and also the lower corners are diagonally opposite.
  • the lower corners form the lowest points of the work surface and the upper corners form the highest points of the work surface.
  • a symmetrical distribution of forces is achieved on the punch.
  • the lower corners are disposed at a same height and the upper corners at an equal height.
  • the symmetry of the cut is further promoted.
  • the two lower corners are connected by a diagonal connection route. Due to this diagonally extending connection route, the punch has no abrupt edges in its deepest regions, which ensures a continuous cut.
  • the diagonal connecting route is preferably curved in its cross section.
  • the diagonally extending connection route can have a circular arc section, wherein a corner diagonal, which extends between the two diagonally opposite lower corners, represents the lowest points of the circular arc section.
  • the corner diagonal divides the connection route thus into two absolutely identical surfaces, whereby a symmetrical cut can take place.
  • the circular arc section preferably has a radius of 30 mm to 500 mm, more preferably 50 mm to 300 mm.
  • the upper and lower corners have a height difference of 0.1 mm to 10 mm, preferably from 0.3 mm to 4 mm.
  • the corners of the punch are preferably rounded.
  • a punching unit essentially comprises a punch and a die according to the invention, wherein at least one of punch and die is movable relative to the other and punch and die thus cooperate during the punching process.
  • the punch 1 is used in a punching unit 2 (see schematic representation in FIG Fig. 1 ) to be used.
  • the punch 1 punches from a cyclically supplied blister 4, which comprises the filled and sealed cups and preferably made of aluminum or PVC, individual blister packs. It is important that the punch 1 does not tip over, otherwise the punching unit 2 has to be blocked and must be readjusted in serious cases, whereby long downtimes of the punching unit 2 may occur.
  • FIG. 2 and 3 an embodiment of a punch 1 according to the present invention is shown.
  • the punch 1 has a working surface 5 with a substantially rectangular shape.
  • the work surface 5 is bounded by four edges 7, the four corners 9, 11 form.
  • the corners are formed as two upper corners 9 and two lower corners 11.
  • the two upper corners 9 are higher than the two lower corners 11 and are diagonally opposite.
  • the two lower corners 11 are also diagonally opposite.
  • the edges 7 each extend obliquely sloping from the upper corners 9 to the lower corners 11.
  • the height difference from the upper corners 9 to the lower corners 11 is between 0.1 mm to 10 mm, preferably between 0.3 mm to 4 mm.
  • the corners 9, 11 of the punch 1 are preferably rounded.
  • connection route 13 connects the two lower corners 11 with each other in the present example case.
  • the connection route 13 is delimited here by two likewise diagonally extending connection path boundary lines 14.
  • the connecting route 13 divides the working surface 5 into a first partial working surface 15 and a second partial working surface 17.
  • the first partial working surface 15 and the second partial working surface 17 run obliquely from the upper corners 9 in the direction of the connecting route 13 and the second partial work surface 15, 17 are the two upper corners 9.
  • the two partial work surfaces 15, 17 ideally have the same shape and the same surface area.
  • connection route 13 has a curved cross-sectional shape.
  • the curvature is preferably formed as a circular arc section, which has a radius of 30 mm to 500 mm, preferably from 50 mm to 300 mm.
  • the width of the connecting route 13 is in the range of 2 mm to 20 mm, preferably 3 mm to 15 mm.
  • connection route 13 there are also other embodiments of the connection route 13 conceivable. Asymmetric curvatures of the connection route 13 are possible as well as connection routes 13 without curvature. In some cases, the connection route 13 may also be omitted and only a corner diagonal present (oblique inverted roof shape).
  • connection route 13 slightly shifted to the in Fig. 2 and 3 is shown, for example, such that the lowest points of the work surface 5 are arranged near the lower corners 11, but in a region of the edges 7.
  • the blister strip 4 is clocked transported in the punching unit 2, so that it is arranged between the die 3 and punch 1.
  • the die 3 has a recess (not shown) which corresponds to the shape and size of the working surface 5 of the punch 1.
  • the punch 1 first strikes the blister band 4 with the two diagonally arranged upper corners 9.
  • the blister strip 4 is then severed along the edges 7 towards the lower corners 11, wherein the punch 1 dips into the recess of the die 3.
  • the arcuate portion of the connecting path 13 and the rounding of the corners 9, 11 provide in the preferred embodiment for a gentle average at the corners 9, 11.
  • the punched blister pack falls down through the recess out of the die 3 and is known with Devices further transported.
  • the punch 1 according to the invention can be used both in the production of aluminum blister packs and PVC blister packs.
  • the punch 1 is thus universally applicable and does not need to be replaced with a material change from, for example, PVC to aluminum.
