Definitions

  • the invention relates to a slitter for trimming sheet material with the features of the preamble of claim 1.
  • Cutters are used primarily in the office to crop paper sheets or transparencies, either individually or as a sheet stack. Common to such cutters that they have a horizontal support plate for the support of the sheet material and that a cutting device is provided on at least one side of the support plate. Roller cutting devices are suitable for the production of particularly smooth cutting edges.
  • a roller cutter has a guide rail extending parallel to one side of the platen and also parallel to the surface of the platen.
  • a knife carriage along the guide rail is guided displaceably.
  • the knife carriage has a roller blade which, on the knife carriage, about a horizontally and transversely to the longitudinal axis of the guide rail extending axis is freely rotatably mounted.
  • the knife carriage itself or the part of the knife carriage, on which the roller blade is mounted, lowered by applying pressure from above vertically to the support plate.
  • the sheet material is placed on the support plate and pushed so far through the guide rail, that the part to be cut over on the other side of the guide rail. Then vertical pressure is applied to the knife carriage, so that the roller blade is lowered in the direction of the sheet material. The cutting of the sheet material is then carried out by moving the knife carriage along the guide rail. The roller blade performs a rotary motion and thereby cuts the sheet material.
  • the guide rail is rigidly fixed end to the support plate.
  • a vertically movable clamping rail which is clamped in the initial position by means of tension springs against the underside of the guide rail.
  • the knife carriage is divided into a guide part and a knife part, wherein the knife part with the roller blade is vertically displaceable relative to the horizontally extending guide rail.
  • a disadvantage of the above-described slitter cutters is that the tension of the sheet material depends on the action on the knife carriage, i. the clamping takes place only at the beginning of the cutting process and also locally concentrated on the position of the knife carriage. Therefore, until the cutting process, there may still be shifts in the sheet material.
  • slitter cutters have been developed which are independent of any distortion of the sheet material from the operation of the knife carriage cause (see. US 5,069,097 A and 5,287,783 A ).
  • a tensioning rail is likewise arranged below the guide rail and is suspended by means of springs on the guide rail.
  • the guide rail itself is vertically movable between a raised starting position and an end position. Before a cutting operation, the guide rail is lowered after positioning of the sheet material from the starting position in the direction of the support plate or the sheet material until it has reached the end position.
  • the clamping rail lays on the sheet material and clamps it against the support plate. The clamping pressure is applied by the springs between the guide rail and clamping rail.
  • the guide rail In the end position, the guide rail is held at the end by means of guide devices and fixing devices in a position which is always the same and thus independent of the thickness of the sheet stack.
  • the guide device is formed on one side of the guide rail as a pivot joint, via which the guide rail can be pivoted lever-like upward. In the starting position, the guide rail is located on the other side outside the guide device and locked with this after taking the end position.
  • Actuators are provided on both sides, over which the guide rail from a to the shelf parallel starting position in the end position conveyed and fixed there.
  • the guide rail itself serves as a clamping device for clamping the sheet material against the support plate.
  • the guide rail is held at both ends in guide means, in a first embodiment on one side via a pivot joint and on the other side substantially vertically displaceable and in a second embodiment on both sides vertically displaceable.
  • an actuating device is provided, via which the guide rail from the starting position, in which its lower-side clamping surface is spaced from the support plate, can be brought into a clamping position in which the clamping surface under bias on the support plate or at underlaid sheet material rests on this itself and braced it against the support plate.
  • a fixing device in the form of a locking device ensures that the guide rail, the once occupied clamping position regardless of Maintains cutting process. Only by loosening the latching device (s) is the guide rail lifted off the sheet material again into the starting position, by means of spring members of a spring device.
  • the above-described slitter is characterized by simple structural design. However, it must be accepted that due to the defined clamping position of the guide rail only a small number of sheets can be cut simultaneously.
  • the invention is therefore based on the object to make a slitter, so that with it a tension of the sheet material before the start of the cutting process is possible that it is structurally simple and therefore inexpensive and that it is also relatively small for trimming relatively thick sheet material or Sheet stack is suitable.
  • the basic idea of the invention is therefore to guide the guide rail in both directions, ie away from the support plate and towards it, so that there is no direct connection to the actuation device, but only via the second spring device.
  • the force is transmitted resiliently to the guide rail via the second spring device.
  • the actuator can be moved against the action of the second spring means even further in the intended end position and fixed there.
  • the clamping position of the guide rail is thus variable according to the thickness of each sheet material to be trimmed and thus independent of the end position of the actuator.
  • the clamping force increases with the thickness of the sheet material or stack of sheets to be trimmed.
  • the roller cutting device according to the invention is characterized by simple construction, because a separate clamping rail and its suspension on the guide rail is not present, but rather the guide rail itself is used for clamping the sheet material.
  • the guide rail is operated only from one end.
  • the actuator on an actuator only on a single guide means and the first spring means is arranged only on this guide means, while the second spring means in the region of both guide means on the one hand between actuator and guide rail and on the other hand between guide means and guide rail in the direction of the support plate is effective.
  • the second spring means presses the guide rail in its initial position in the region of the guide means without actuating means on the support plate.
  • the guide rail is pivoted in the starting position to the guide means without actuator upwards and thus releases a gap between the clamping surface of the guide rail and the support plate to push there sheet material under the guide rail can.
  • the actuator is pressed down, causing the guide rail rests with the clamping surface of the sheet material against the action of the second spring means, which is guided in the guide means without actuator end of the guide rail of the support plate against the action of the second spring means lifts in alignment with the surface of the sheet stack.
  • the second Spring device is designed so that the guide rail or its clamping surface remains in further movement of the actuator in the direction of its end position in planar contact with the sheet material and thus in a horizontal position. This can be done by appropriate adaptation of spring members of the second spring means in the region of both guide means.
  • a symmetrical design of the slitter is preferred.
  • the movement of the guide rail from the starting position into the clamping position is effected by actuating means at both ends by hand, which can be done successively or simultaneously.
  • This embodiment has the advantage that a particularly uniform support of the guide rail on the sheet material can be realized.
  • the second spring device should have at least one spring element, each in the area the associated guide device is arranged.
  • at least one spring element should also be provided, in each case in the guide device provided with an actuating device.
  • the spring elements are expediently designed as helical springs, which are preferably subjected to pressure.
  • the spring means of first and second spring means are conveniently arranged within the guide means (s) so as to face each other vertically.
  • the spring member or should the spring members of the first spring means act on the underside of the guide rail, wherein the spring member or the spring members can be supported on the support plate or can.
  • the spring elements of the second spring device expediently act on the upper side of the guide rail.
  • the fixing device (s) is or are formed in a manner known per se as a latching device (s), with which the respectively associated actuating device automatically latches in the end position.
  • the latching device (s) should each have an operating element, by the actuation of the locking position can be unlocked.
  • the actuating device may have at least one actuating element which is designed as a pushbutton guided vertically in the respective guide device.
  • roller blade relative to the guide rail in the direction of the support plate against the action of a return spring is lowered, for example by the entire knife carriage is mounted vertically movable on the guide rail or only the part on which the roller blade is mounted and which is vertically movable relative to the remaining part of the knife carriage via a corresponding handle.
  • slitter 1 has a support plate 2, the top side has a horizontal sheet support 3.
  • a roller cutting device 4 is arranged, which serves for the trimming of sheet material 5 placed on the sheet support 3.
  • the roller cutting device 4 has a parallel to the longitudinal side of the support plate 2 and parallel to the sheet support 3 extending guide rail 6, which is embraced from above on both sides by a blade carriage 7, which is displaceable along the guide rail 6.
  • the knife carriage 7 is divided into an inner and therefore therefore not visible guide member which includes the guide rail 6 positively, and an outer blade part 8 which is movable from the raised position shown against the action of a spring not visible here vertically downwards into a cutting position ,
  • the knife carriage 7 has to handle it at the top of a handle 9, which is intended for a palm rest and can be moved over the blade carriage 7 along the guide rail 6 and simultaneously lowered down.
  • the knife part 8 has a covered by a blade cover 10 roller blade, the bottom side slightly protrudes beyond the blade cover 10 and sits freely rotatable on a horizontally and transversely to the longitudinal axis of the guide rail 6 extending blade axis.
  • the guide rail 6 projects at both ends into guide blocks 11, 12, in which the guide rail 6 is guided laterally and at the same time is vertically movable.
  • the Füxhrungsblöcke 11, 12 are rigidly connected to the support plate 2.
  • actuators 13, 14 are guided, and also laterally and vertically movable. They grasp the ends of the guide rail 6 at the top, on the front side and on both vertical sides.
  • the actuators 13, 14 have planar actuating webs 15, 16, by means of which pressure can be exerted by hand in the direction of the sheet support 3.
  • each have a locking member 17, 18 is arranged.
  • the locking members 17, 18 are mounted in the guide blocks 11, 12 horizontally parallel to the guide rail 6 slidably. From the detent position shown so they can be moved in each case outwardly in a Entrastrus.
  • FIGS. 2 to 4 The closer training and the interaction of the actuators 13, 14 and the locking members 17, 18 results from the FIGS. 2 to 4 based on the limited to the right part sectional views.
  • the slitter 1 is mirror-inverted, so that the following statements apply mutatis mutandis to the description of the left-side end of the guide rail 6.
  • the actuating member 18 is partially visible, with the above-mentioned actuating bar 16 and an integrally formed, the end face of the guide rail 6 bordering latching element 20.
  • the locking element 20 has a wedge-shaped latching recess 21 which is closed at the top by a latching web 22. This cooperates with a detent 23, which protrudes from the top side protruding part of the locking member 18 down in the space enclosed by the guide block 12 space.
  • the above-mentioned spring element which acts on the latching lug 23 and thus the locking member 18 in the direction of the end face of the Guide rail 6 or acted upon in the direction of the actuator 14.
  • the guide rail 6 consists essentially of an aluminum profile. On the underside, it has an elastomeric plastic existing strap 24 which extends across the width of the sheet support 3. The underside of the clamping band 24 forms a clamping surface 25th
  • the guide rail 6 is each end side in the region of the guide blocks 11, 12 acted upon at the bottom by a compression spring 27. Both compression springs 27 are supported on the support plate 2 in each case in a mirror-symmetrical arrangement.
  • a second compression spring 28 is arranged in each case.
  • the guide rail 6 is thus not rigidly connected at both ends with the actuators 13, 14, but is clamped by the respectively acting in the opposite direction of compression springs 27, 28 and is thus both against the support plate 2 and against the actuators 13, 14 movably guided ,
  • the guide rail 6 Before a cutting operation, the guide rail 6 is in a raised starting position. She is in the Figures 2 and 5 to see. In this starting position, the clamping surface 25 has a clear distance to Sheet support 3. In this initial position, the guide rail 6 is supported on the end of the first compression springs 27. It is pressed by these springs 27 against the second compression spring 28, which in turn are supported on the undersides of the actuating webs 15, 16.
  • the actuators 13, 14 also assume a starting position in which they project upwards over the surface of the guide blocks 11, 12.
  • the locking lugs 23 project into the respectively associated latching recesses 21 of the latching elements 20.
  • sheet material 5 is to be trimmed, it will - as is the case in particular FIG. 1 can be seen - placed on the sheet support 3 and then pushed through the gap between the guide rail 6 and sheet support 3 until it projects on the other side so far on the plane of the roller blade, as it should be cropped. Then, the guide rail 6 is depressed to clamp the sheet material 5 between clamping surface 25 and sheet support 3 linear. This is first by the trimming of a single sheet and with reference to the Figures 3 and 6 explained.
  • the two actuators 13, 14 are pressed by applying the actuating webs 15, 16 down. Since the second compression springs 28 have a higher spring constant than the first compression springs 27, the first compression springs 27 are compressed in the first place, the second Compression springs 28 only very slightly. This is continued until the clamping surface 25 comes into contact with the sheet material 5. Due to the resistance, the guide rail 6 can not be moved further, ie it has reached its clamping position. However, the locking members 17, 18 have not yet reached their end position, ie they are even further moved down against the resistance of the second compression springs 28, and that until the locking webs 22 of the locking recesses 21 come to rest below the locking lugs 23. This creates a clearly audible click.
  • the locking lugs 23 now block the actuators 13, 14 at their mobility upwards.
  • the force exerted by the guide rail 6 on the sheet material 5 clamping force is essentially determined by the second compression springs 28. So that the pressure is evenly distributed over the length of the guide rail, the compression springs 28 are identical and equally far away from the center of the guide rail 6 , At the same time press the second compression springs 28, the locking webs 22 with their tops against the undersides of the locking lugs 23rd
  • the actuators 13, 14 In order for the actuators 13, 14 to reach their prescribed end position, they must be depressed as much as in the case of trimming a single sheet. But the second compression springs 28 are compressed much more, as well as the comparison between Figures 3 and 6 on the one hand and 4 and 7 on the other hand. Correspondingly higher is the force exerted on the sheet material stack 29 clamping force when the locking members 17, 18 in the FIGS. 4 and 7 have reached shown end position in which rest the latching webs 22 on the bottom side of the locking lugs 23. In both cases, close the surfaces of the actuating webs 15, 16 flush with the tops of the guide blocks 11, 12, ie the actuators 13, 14 have a defined end position in contrast to the clamping position of the guide rail 6, which depends on the thickness of the sheet material. 5
  • the knife part 8 is pressed down by applying the handgrip 9, so that the roll knife protruding below presses into the sheet material 5 or the sheet material stack 29.
  • the cutting operation is performed.
  • the now trimmed sheet material 5 or sheet material stack 29 is still clamped between guide rail 6 and sheet support 3.
  • the locking members 17, 18 displaced by applying pressure in the direction of the guide rail 6 away outward against the action of the spring elements, and indeed so far until the locking lugs 23 come out of engagement with the locking webs 22.
  • the actuators 13, 14 can now move back up to their starting position ( Figures 2 and 5 ), which leads to the relaxation of the compression springs 27, 28.
  • the compression springs 27 provide for raising the guide rail 6 to the starting position according to the Figures 2 and 5 , The sheet material 5 or the sheet material stack 29 are then exposed and can be removed.
