Definitions

  • the invention relates to a cutting device for cutting sheet material with a sheet support and associated with at least one of the sheet support roller cutting device having a guide rail on which a cutting carriage is slidably guided, which has a knife holder which is rotatably mounted about an axis parallel to the guide rail and of Hand is rotatable and on which at least two disc blades are freely rotatably mounted about knife axes which are perpendicular to the axis of rotation of the knife holder, the disc diameter can be brought by turning the knife holder from one inactive position in a projecting towards the sheet support cutting position and wherein a blocking device is provided, which holds the knife holder in the cutting position of a disc diameter.
  • manually operable cutters are used both in the office and in the private sector, which essentially consists of a sheet support in the form of a sheet material partially or completely receiving pad plate and a mostly on a Side of the pad plate arranged cutting device exist.
  • Levers and slitter cutters are common in the cutters. The latter have a straight guide rail running above and parallel to the sheet support, on which a knife carriage is displaceable is guided.
  • rotatably mounted disc knife is arranged, which is movable from a raised initial position in a lowered cutting position. The cutting process is effected by the knife carriage is moved after taking the cutting position by the disc knife along the guide rail.
  • cutters have a roll cutting device whose blade carriage have several, usually different disc diameter, for example, a disc blade for straight cut, one for corrugated section and one for perforations.
  • a disc blade for straight cut for example, a disc blade for straight cut, one for corrugated section and one for perforations.
  • Such cutters are in the EP 1 533 088 and the DE 20 2008 011 851 U1 disclosed.
  • the three disk blades are each freely rotatably mounted on a knife holder, which is mounted in the knife carriage about a horizontal, extending transversely to the longitudinal axis of the guide rail axis of rotation.
  • the disc blades are distributed over the circumference of the blade holder by 120 angular degrees.
  • the respective desired disc diameter can be brought from an inactive position into a downwardly projecting cutting position.
  • the housing of the knife carriage can either be moved relative to the stationary mounted guide rail or together with this downward and thus pressed the disc knife projecting below into the sheet material to be trimmed. Again, the cutting process is effected by moving the knife carriage along the guide rail.
  • a similarly trained cutter is the US 2005/0223863 A1 refer to.
  • this document discloses a cutting device in which four disc blades are mounted with their knife axes at right angles to each other on a knife holder which is rotatably mounted about a vertical axis. This arrangement is relatively complicated because the respective slice knife to be brought into cutting position must be moved vertically.
  • a generic cutter in which the knife holder - different from the state of the art shown in Figure 7 of this document - is rotatably mounted about an axis parallel to the longitudinal axis of the guide rail extending axis.
  • the disk knives are freely rotatably mounted on the knife holder with knife axes which lie in a plane extending perpendicularly to the axis of rotation of the knife holder, but the axes of rotation do not pass through the axis of rotation of the knife holder.
  • a blocking device which holds the knife holder in the cutting position.
  • the knife holder on a sawtooth disc which cooperates with a pivotally mounted on the knife carriage pawl such that the knife holder in a rotational direction can not move when one of the disc knife is in the cutting position.
  • the cutting force acting on this disc cutter during the cutting process is intercepted by the pawl. Due to the special nature of the storage of the disc knife is then a rotation of the knife holder in the other Direction not possible. Only after completion of the cutting operation, the knife holder can be rotated in this direction to bring another disc knife in the cutting position.
  • a disadvantage of this type of cutters is the complex design of the knife holder and the disc knife mounted thereon, including the blocking device.
  • the formation of the knife holder requires a relatively large space below the knife carriage to allow the rotation of the knife holder. It remains unclear how the knife carriage can be brought with the disk knife located in the cutting position in abutment with the sheet material to be trimmed.
  • the invention has for its object to make a cutter of the type mentioned easier and with a secure guide.
  • the blocking device are designed as a form-locking interlocking guide elements on the guide rail and knife holder, which holds the knife holder in a rotational angle blocking its rotational position, when one of the disc knife is in a cutting position, and that the guide rail has a release area, in which it does not have the rotatability of the knife holder blocking guide elements.
  • the basic idea of the invention is thus to block the knife holder when one of the disk cutters is in a cutting position via guide elements in its rotatability, which are provided on the one hand on the guide rail and on the other hand on the knife holder itself and interlock positively. In this way, an easy trainee and safe guidance is guaranteed.
  • the knife axes lie in a plane extending perpendicularly to the axis of rotation of the knife holder, so that the knife carriage has a small overall length. Furthermore, the invention provides that the disc blades extend radially to the axis of rotation of the knife holder. Due to the guide through the guide rail this type of storage of the disc knife is possible. This creates space for the star-shaped arrangement of a variety, for example, nine disc blades.
  • the guide rail has two side by side and at a distance from each other extending rail elements and each located in the cutting position disc diameter passes through the guide rail between these rail elements in the direction of the sheet support.
  • the guide rail is divided in the longitudinal direction into two spaced-apart rail elements. These rail elements enclose the respective disk knife in the cutting position and form an obstacle against unintentional access to the disk knife, i. Rail elements minimize the risk of injury from the disc knife in the cutting position.
  • the engagement elements can be designed in various ways. So it is possible, the engagement elements as at least one pair, each consisting of a guide on the one hand and a guide web enclosing it on the other hand, form, whereby ultimately it does not matter crucially whether the guide web on the guide rail and thus the guide groove on the knife carrier or vice versa are formed.
  • the knife holder has on both sides of each disc diameter guide elements which are in engagement with a respective guide element on the guide rail.
  • the guide rail side guide elements should be distributed to the two rail elements.
  • engagement means the mutual contact of the guide elements.
  • the guide rail has two oppositely oriented guide shoulders and the knife holder has a guide shoulder on each side of each disc blade, wherein a guide shoulder of the guide rail bears against a guide shoulder of the blade holder.
  • the guide shoulders should each be formed in mirror image to the disc cutter located in the cutting position. The aforementioned measures ensure a straight-line guidance of the knife holder and thus of the disc knife located in the cutting position.
  • the guide rail can have at least one upstanding guide web on the guide element, which in each case engages in a guide groove formed in the knife holder and has, for example, the above-mentioned guide shoulder.
  • the complementary guide heels can then be formed by the side walls of the guide grooves.
  • the intended for the change of the disc diameter release area should be expediently formed at one end of the guide rail. However, it can also be provided at both ends of the guide rail in each case a release area.
  • the guide of the knife holder is lifted on the guide rail with the result that the knife holder twisted by hand and thus another disc knife can be brought into cutting position.
  • the knife holder should protrude at one end of the cutting carriage and there have a knob, for example in the form of an externally knurled knob or such with a projecting handle bar.
  • the knife holder has externally visible markings, which indicate the cutting position of the disc diameter. This is particularly useful when the position of the disc diameter from the outside are not recognizable, for example, because they are arranged protected in order to avoid injury or damage within the cutting carriage.
  • the cutting carriage should preferably have a recess on the top side to make the mark visible.
  • the knife holder is associated with a latching device which engages upon reaching a cutting position.
  • the latch gives the operator a reliable Feedback on reaching the cutting position.
  • the cutting carriage has a carriage housing with side walls which border the guide rail on both sides and are guided there on the guide rail, preferably in the form of a dovetail guide.
  • the cutting carriage can be guided on the guide rail such that it can be moved relative to it by exerting a compressive force from above in the direction of the sheet support, for example against the action of an upwardly directed spring.
  • the guide rail is rigidly attached at their ends.
  • the guide rail is resiliently supported at its ends on the sheet support.
  • the knife holder is divided in the direction of the axis of rotation perpendicular to her and the disc diameter in the parting plane are guided in recesses in both parts of the knife holder. In this way, the assembly of the knife holder and also easy to make the guidance of the disc knife in the knife holder.
  • the knife holder itself has expediently a drum shape, which is preferably inserted from below into the knife holder.
  • the disc knife should be inaccessible to the side and top, so be completely encapsulated so far, either by the carriage body of the cutting carriage and / or by the knife holder itself. As a result, the disc blades are protected against accidental contact by operators.
  • the cutting device according to the invention is therefore also suitable for use by children.
  • the cutting device 1 shown in the figures has a short bar-like sheet support 2, from the opposite rear side a stop bar 3 is folded out at right angles.
  • a roller cutting device 4 which consists essentially of a guide rail 5 and a cutting carriage 6, which is guided along the guide rail 5 freely displaceable on her.
  • the guide rail 5 is divided into a above the sheet support 2 at a distance to this extending first rail part 7 and in an adjoining second rail part which is formed in a head part 9 of the sheet support 2.
  • the first rail part 7 is supported at both ends by not shown here, vertical coil springs on the sheet support 2, so that the first rail part 1 from the initial position shown in which it is spaced from the top of the sheet support 2, in the direction of this top can be moved by applying pressure in this direction.
  • the first rail part 7 is composed of two mutually parallel, mirror-symmetrical rail elements 10, 11, which are spaced apart and are connected to each other via provided in the end regions connecting webs, of which only the left-side connecting web 12 can be seen. In the space between the first rail part 7 and sheet support 2, a paper sheet 13 is inserted for the purpose of trimming.
  • the cutting carriage 6 has a housing 14 which has two vertical, mutually parallel end walls 15, 16 which are connected via likewise vertical and mutually parallel side walls 17, 18. End walls 15, 16 and side walls 17, 18 are bounded by a spherically curved top wall 19 on top.
  • a drum-shaped knife holder 20 is arranged, which in the region of FIG. 1 visible end walls 15 in a bearing pin 21 terminates, which is locked there in a bearing slot 22 such that the bearing pin 21 and thus the blade holder 20 itself is rotatably mounted about a parallel to the longitudinal axis of the guide rail 5 extending axis of rotation.
  • a bearing slot 23 is provided, in which the blade holder 20 is rotatably mounted with a not visible there bearing projection.
  • Fixed to this bearing projection is a knob 24 with a handle bar 25. About this knob 24, the knife holder 20 can be rotated from the outside about its longitudinal axis.
  • the top wall 19 has a recess 26, which makes a cylindrical portion 27 of the knob 24 partially visible.
  • the knife holder 20 is - seen in its longitudinal direction - divided into a first holder portion 28 and a second holder portion 29, wherein the dividing plane is perpendicular to the axis of rotation of the knife holder 20.
  • Both holder sections 28, 29 point in the division plane respectively opposite pairs of complementary bearing recesses 30, 31 and 32, 33 and 34, 35, wherein in each pair of opposing bearing recesses 30 to 35, a disc blade 36, 37, 38 is inserted (see in particular the Figures 3 and 4 ).
  • the disc blades 36, 37, 38 extend radially to the axis of rotation of the knife holder 20 and have central bearing journals 39, 40 and 41, 42 and 43, 44, over which they are freely rotatably guided in the bearing recesses 30 to 35.
  • the disc blades 36, 37, 38 project radially beyond the circumference of the blade holder 20. In this case, the vertical disc knife 36 is in a cutting position, while the other disc blades 37, 38 assume an inactive position.
  • FIG. 3 can recognize, engage in the longitudinal grooves 45, 46 which are adjacent to the cutting blade 36 located in the cutting position, guide webs 56, 57 which rise symmetrically to the plane of the disc blade 36 obliquely upwards from the first rail part 7 of the guide rail 5.
  • the guide webs 56, 57 extend over the entire length of the first rail part 7.
  • the outside edges of the guide rail 5 have obliquely downwardly directed chamfers 61, 62, which are frictionally bordered by guide grooves 63, 64, which are formed in the inner sides of the side walls 17, 18.
  • the cutting carriage 6 is guided displaceably along the guide rail 5, and - in particular FIG. 4 shows - into the second rail part 8 into it.
  • FIG. 4 indicates that the second rail part 8 of the guide rail 5 has no guide webs 56, 57. Rather, there is provided in the middle region of a release area 65 which is lowered so far that the knife holder 20 and thus the disc blades 36, 37, 38 mounted therein are freely movable, ie the knife holder 20 can - in the view FIG. 4 - Are rotated counterclockwise to bring instead of the disc diameter 36 another disc diameter 37 or 38 in the vertical cutting position. This is then done by appropriate manipulation of the knob 24 when the cutting carriage 6 in the in FIG. 4 shown position has been moved, that is on the second rail part 8 of the guide rail 5 is located.
  • the disc blades 36, 37, 38 may be formed differently, for example, the disc blade 36 for a linear section, the disc diameter 37 for a wave cut and the disc diameter 38 for a perforation. However, it is also possible to provide the same trained disc diameter 36, 37, 38, so that the disc blades 37, 38, which are initially in their inactive positions, are kept in reserve as a replacement, the disc cutter 36 should become dull.
  • the cutting process is triggered by the cutting carriage 6 is pushed by the second rail part 8 in the first rail part 7 and then that from the top of the housing 14, a pressure in the direction of the sheet support 2 is applied.
  • cutting carriage 6 and guide rail 5 are lowered against the action of the coil springs supporting them, so that the disk blade 36 located in the cutting position makes contact with the paper sheet 13.
  • the trimming is effected.
