Definitions

  • the present invention relates to an apparatus and a method for cutting flat material blanks from sheets of flat material.
  • These may in particular be blanks made of thin, relatively flexible cardboard, such as folding carton blanks for drug packages or the like.
  • the known device for rotary cutting of flat material blanks from sheets has the disadvantage of a relatively large expenditure on equipment. It requires a total of five rollers for cutting and separating the blanks from or from the sheets.
  • a device for cutting out flat material blanks from sheets of sheet material which has a cutting roller and a mating roller cooperating therewith, between which there is a nip in which the flat material sheets for cutting out the flat material blanks can be inserted to form a residual material, and in which both the cutting roll as well as the counter roll are each formed as a suction roll with a lateral surface, which has a plurality of Saugluftö Maschinenen, the Saugluftbeaufschlagung the cutting and the counter roll is such or controllable that immediately after cutting the flat material blanks on the outer surface of the cutting or counter-roll and the residual material on the lateral surface of the counter or cutting roller - that is on the corresponding other roller - can be transported further.
  • the residual material may be either only the skeletal grid of the flat material sheet or, if in and / or between the flat material blanks Inner cutouts are provided - to act on the skeleton and in addition the waste snippets of the inner cutouts.
  • the advantage of the invention is that all outer and inner contours of the flat material blanks are cut out with a single pair of rollers and at the same time the flat material blanks are separated from the residual material, in particular the residual grid.
  • the expenditure on equipment is correspondingly low compared to the prior art.
  • a further transport of the flat material sheets for the purpose of further production steps after leaving the nip is no longer necessary because only the residual material of the waste disposal is supplied.
  • a blank sheets carrying the blanks no longer exists after the cutting process according to the invention.
  • both the cutting and stamping process and the taking over of the flat material blanks by one roller and the taking over of the remainder material by the other roller take place.
  • Which of the two rolls takes over the flat material blank and which of the two rolls takes over the residual material can be selected as needed in the context of the present invention. It is essential to the invention that after the cutting out of the flat material blanks, no joint transport of the blanks and of the residual material takes place any more.
  • a counter-cutting strip to be separately retained in the machine is also eliminated. Instead, this invention is arranged on the lateral surface of the counter roll.
  • suction-controlled suction channels can be provided in the rollers whose Saugluftbeetzung be controlled by means of suitable control valves can.
  • those suction air openings of the cutting roller or the counter-roll, on which no suction effect is desired due to the geometry of the flat material blanks or of the residual material to be masked with a tape or the like.
  • the present invention makes it possible, especially in the area of the bearings of each of the two rollers, to save space by providing only a single control valve per roller.
  • the control valve of the cutting roller controls only their Saugluftbeierschlagung for holding, transporting and dispensing the flat material blanks while the control valve of the mating roll exclusively their Saugluftbeaufschlagung for holding, transporting and dispensing the residual material controls or vice versa.
  • the cutting roller is designed as a combined cutting and embossing roller for cutting out the flat material blanks and simultaneously producing impressions and / or preliminary breaks in the flat material blanks.
  • the embossings to be produced can be logos or inscriptions on the one hand and embossed pre-break lines on the other hand. The latter represent material weakenings in the form of creases in the flat material blank, along which subsequent folding operations in the context of folding carton production take place from the flat material blanks.
  • the cutting roller is formed as a combined cutting and embossing roll, advantageously eliminates a separate embossing station in the manufacturing machine and the device of the invention takes over the functions cutting, embossing and separating the flat material blanks of the residual material (Nutzentrennung).
  • Cutting roller and counter roller are pressed against each other by means of suitable devices to produce the required cutting and / or embossing forces in the nip.
  • the line of action of the corresponding pressing force can pass through the centers of rotation of the cutting and counter-roller.
  • the cutting and counter-rollers can be mounted and guided with play in the direction perpendicular to the aforementioned line of action.
  • the rollers can be arranged such that their centers of rotation are offset from each other in the direction perpendicular to the line of action. As a result, the two rollers are always in a stable equilibrium position.
  • rollers are arranged offset to one another in such a way that one of the two rollers with their suction surface acted upon by suction absorbs the flat material sheets at the front end thereof and transports them further into the nip.
  • additional guide means can be provided which ensure that the sheets of sheet material are pressed into abutment against the lateral surface of one of the two rollers and transported to the nip.
  • a method for cutting out flat material blanks from flat material sheets, in which the flat sheets for cutting the flat blanks are introduced into a nip between a cutting roll and a mating roll interacting therewith and a remainder material is formed, and in the immediately after cutting out the flat blanks held by suction on the lateral surface of the cutting or counter-roller and further transported on this while the residual material is held by suction on the lateral surface of the counter or cutting roller and transported on this, so that immediately after cutting a separation of the flat material blanks of the residual material ,

  • the lateral surface 6 of the cutting roller 2 carries a plurality of male parts 11 for producing pre-break or fold lines in the flat material blanks.
  • the counter-roller 3 carries on its lateral surface 7 cooperating with the cutting blade 10 and correspondingly closed circumferential counter-cutting bar 12 and the dies 11 cooperating matrices thirteenth
  • Cutting roller 2 and counter-roller 3 may be formed as solid rollers, so that the cutting blade 10 and the counter-cutting bar 12 and the male part 11 and the dies 13 are integrally formed on them.
  • the alternative is to form the cutting blade 10 and the male part 11 or the counter cutting strip 12 and the dies 13 on film sheets, which can be releasably secured to the lateral surfaces 6 and 7 of the cutting roller 2 and counter-roller 3.
  • the cutting roller 2 is thus characterized by having the active cutting or embossing tools, while the counter-roller 3 is provided with the passive cutting or embossing tools.
  • the cutting roller 2 can of course also be designed as a pure cutting roller, so that it only the active cutting tools carries, while then the counter roll 3 carries only the passive cutting tools.
  • Fig. 1 are the axially extending in the cutting roller 2 and the counter-roller 3 Saugluftkanäle 14 and 15 can be seen.
  • Each suction air channel 14 or 15 is connected via a plurality of substantially radially extending suction air holes 16 and 17 with the lateral surface 6 and 7 in fluid communication.

From the in Fig. 5 shown flat sheets B were cut out three rows of flat material blanks Z, wherein in each row five flat blanks Z are arranged. This in Fig.
  • the flat material blanks Z in the outer region of the flat material sheet B and not shown hatched material is referred to as the residual grating R.
  • inner cutouts 1 of the flat material sheet B In the case between the individual rows of flat material blanks Z lying material which in Fig. 5 hatched, are so-called inner cutouts 1 of the flat material sheet B. Interior cutouts in the form of windows and the like can also be arranged in the flat material blanks Z itself.
  • the flat material blanks Z adhere to the lateral surface 6 of the cutting roller 2. They are transported on the lateral surface 6 in the embodiment shown by an angular distance of about 90 °, before being transferred to a transport roller 19, which is also formed as a suction roll. Alternatively, any other type of transport device for taking over the flat material blanks Z of the cutting roller 2 is conceivable.
