DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS OF THE INVENTION

(11) The cutting machine 1, which is shown in FIG. 1 and is in the form of a guillotine cutting machine, serves to cut stacked, sheet material, in particular such material which is composed of paper, board, foil or the like, which is in cuboidal form. The cutting machine has a stand 2 with an upper gantry frame 3, and also a table 4. The table 4 is provided with an upper, horizontal table surface which serves to receive the stack, be it a stack of material which is to be cut or a stack of cut material, the latter also being referred to as a stack of sheets. The table surface 5 therefore extends perpendicular to the plane of the drawing sheet. A cutting blade 6 which can be lowered and raised is mounted in the gantry frame 3, and a pressing bar 7 which can likewise be lifted and lowered in the gantry frame 3 is mounted behind said cutting blade. The pressing bar 7 serves to fix the material which is to be cut, by the pressing bar 7 pressing the stack of material which is to be cut against the table 4 in the lowered position. The cutting blade 6 can be moved from the upper end position, which is illustrated in FIG. 1, to a lower end position, in which it enters a cutting strip which is made in the table 4, during swinging cutting by means of a crank drive. The pressing bar 7 can be lowered from the raised position, which is illustrated in FIG. 1, to the lowered position, in which it rests on the stack, by means of a drive. In the raised position of the blade 6 and pressing bar 7, the pressing bar 7 extends somewhat below the level of the blade 6, and therefore the blade edge is not exposed. The drive motor for the cutting blade 6 is arranged in the right-hand-side region of the gantry frame 3 and is accessible through a flap 8 which closes an opening in the gantry frame 3. A feed device is provided in the region of the rear table part, the said feed device having a backgauge 9 which is designed in a known manner and has a front rake section 10 which serves to feed the stack, which is to be cut, in the direction of the operator, perpendicular to the cutting plane. That side of the backgauge 9 which faces the operator runs parallel to the cutting plane of the cutting blade 6. The backgauge 10 can be moved forward and backward in the region of the rear table part. In the upper, horizontally running section of the gantry frame 3, said gantry frame is provided with an operator control and information display 11 which is a touchscreen. The cutting machine 1 is operated with two hands by two operator control keys 12 being provided in the front region of the table 4, at a distance from one another. This ensures, in principle, that the operator, when operating the cutting machine 1 and therefore initiating cutting, cannot reach into the region of the cutting blade 6 with his hands. The cutting machine is further provided with side stops 13 in the region of the two sides in order to position the material to be cut against one or other stop.

(12) Beneath the cutting blade 6 and the pressing bar 7 which are located in raised positions, an opening 14 is formed in the gantry frame between said cutting blade and pressing bar and the table surface 5. The maximum dimensions of the material, which is to be cut, in respect of width and height is limited by said opening 14. Arrangements 15 which, given the same starting position, are arranged symmetrically to a central plane 16 which is arranged perpendicular to the cutting plane, therefore perpendicular to the drawing sheet, are located to the side of the region of the table 4 which faces the operator, that is to say to the side of the opening 14. The respective arrangement 15 is formed substantially by a light barrier housing 17, light barriers 18 which are accommodated by said light barrier housing, and a cover element 19. The light barriers 18 of the two arrangements 15 serve to guard the space in front of the cutting blade, and the respective cover element 19 can be pivoted from the position which is illustrated in the drawing figures to an end position in respect of the associated light barrier housing 17 in which the light beams or light signals from the light barriers 18 are interrupted. This is important particularly for the arrangement 15 which is illustrated on the right-hand side if, after the cover element 19 is pivoted into the light beams from the light barriers, the flap 8 of the gantry crane 3 is opened and servicing work can be performed on the cutting machine 1, in particular on the drive of the cutting blade 6.

(13) An electrical machine controller 20 for the functions of the guillotine cutting machine 1 is arranged behind a cover in the stand 2 of the guillotine cutting machine 1. Said machine controller 20 is shown by a region which is illustrated using dashed lines.

(14) Both the operator control and information display 11, and also, in addition to this, an operator control unit 21 which has, in particular, an on/off switch 22 for switching on and switching off the guillotine cutting machine 1, is arranged on that side of the gantry frame 3 which faces the operator. The table 4 has, on its side which faces the operator, in the center of the table 4, a hand wheel 23 which allows the backgauge 9 to be slowly moved forward or backward by rotation by means of a rotary potentiometer, which interacts with the electrical machine controller 20, when the material which is to be cut is intended to be positioned exactly with respect to the cutting plane of the cutting blade 6 manually by means of the backgauge 9. Furthermore, the guillotine cutting machine 1 has a centrally arranged foot pedal 24 in the region of the front side of the stand 2 in the region of the lower end of said stand. The operator of the cutting machine 1 can move the pressing bar 7 into a cutting indication position by operating said foot pedal 24, the pressing bar being positioned at a short distance above the stack, which is to be cut, in the cutting indication position and therefore it being possible to align cutting markings on the topmost sheet of the stack with respect to a cutting indication line of the pressing bar 7 exactly by means of the operator manipulating the stack. The stack is generally manipulated in this way by the operator grasping the stack with both hands or acting on the sides of the stack by means of one or two alignment devices.

(15) FIG. 2 shows, in a highly simplified manner, the cutting system 25 according to the invention comprising the above-described cutting machine 1, which is illustrated in an only very simplified manner in FIG. 2, and an alignment device 26 which can be manually manipulated and is manipulated by the operator. Said FIG. 2 shows that the cutting blade 6 is held in a blade holder 27 which constitutes the actual mounting of the cutting blade 6 in the gantry frame 3. The cutting blade 6 is of wedge-like design, and therefore, when the shown overall stack 28 is cut, a partial stack which is displaced into the shape of a parallelogram is separated. FIG. 2 shows the stack 28 in its position in which it is fed beneath the cutting blade 6 by means of the backgauge 9 with the stack 28 being pressed by the pressing bar 7, before cutting is executed.

(16) A first exemplary embodiment of the alignment device 26 is shown in FIG. 4. The alignment device 26 has a first cuboidal plate 29 with a lower flat surface 30 and a second, likewise cuboidal plate 31 which is arranged perpendicular to said plate 29 and has, on that side which is averted from the plate 29, a flat surface 32 which is arranged perpendicular to the surface 30. The surface 30 constitutes a support surface, it being possible for the alignment device 26 to be placed onto the table surface 5 of the table 4 in the region of said support surface. The surface 32 of the alignment device 26 constitutes an alignment surface, the alignment device 26 making contact with the material, which is to be cut, in the region of said alignment surface for alignment purposes. Heating plates 29 and 31 have the same length and a grip part 33 is connected to the two plates 29 and 31 approximately halfway along the length of the respective plates 29 and 31, said grip part having a grip recess 34. The grip part 33 is in the form of a triangular body which exhibits the grip recess 34, wherein the two limbs 35, 36 of the grip part 33, which form a right angle with one another, are connected to the plates 29 and 31. A web 37 of the grip part 33 connects the ends of the two limbs 35 and 36 which are averted from one another. The alignment device 36 is grasped by a hand of the operator in the region of said web 37. The associated ends of limb 36 and web 37 have operator control elements 38, 39 and 40 at the transition from the webs 37 to the limb 36. The operator control element 38 serves to control the function of advancing the backgauge, that is the movement of the backgauge 9 forward in the direction of the cutting plane. The operator control element 39 is intended for controlling the function of returning the backgauge. The operator control element 40 can be used to change the speed at which the backgauge is advanced and returned. If the operator control element 40 is moved, for example, to a switching position which causes the backgauge to move quickly, subsequently pressing the operator control element 38 leads to the backgauge being advanced quickly, and pressing the operator control element 39 leads to the backgauge being returned quickly. If the operator control element 40 is in the other switching position, pressing the operator control element 38 causes the backgauge to advance slowly, and pressing the operator control element 39 causes the backgauge to return slowly.

(17) The operator control elements 38, 39 and 40 interact electrically with further electrical components of the alignment device 26, specifically an electrical controller which interacts with the electrical machine controller 20 of the cutting machine 1. Said electrical controller, which is illustrated using dashed lines and denoted by reference numeral 41 in FIG. 4, is integrated into a hollow space in the plate 31, which hollow space is open toward the grip part 33, and closes said hollow space by means of a cover 42.

(18) FIG. 5 illustrates the fundamental design of the cutting machine 1 and alignment device 26 in respect of the control-related interaction of said cutting machine and alignment device:

(19) The cutting machine 1 has a transmitter and receiver which are associated with the machine controller of said cutting machine, and the alignment device 26 has a transmitter and receiver which are associated with the electrical components of said alignment device. Firstly, the transmitter of the cutting machine 1 and the receiver of the alignment device 26 interact, and secondly the transmitter of the alignment device 26 and the receiver of the cutting machine 1 interact. The data which is received by the receiver of the alignment device 26 can be displayed on a display of the alignment device 26. Data or commands can be input or read into the operator control unit 21 by means of a keypad, a touchscreen, a mobile data memory or a scanner, and are transmitted to the receiver of the cutting machine 1 by means of the transmitter of the alignment device 26. In principle, it would also be entirely possible to process said data internally in the alignment device 26 and, in particular, to display said data or processed data on the display of the alignment device 26. This is the case particularly when the alignment device 26 is used independently of the cutting machine 1.

(20) In principle, the alignment device 26 can be provided with an access barrier, in particular an electronic access barrier, wherein activation of one, several or all of the electrical functions of the alignment device 26 can be blocked by means of the access barrier.

(21) The manner of operation of the alignment device 26 according to the exemplary embodiment of FIG. 4 will be explained below with reference to the illustrations in FIGS. 2 and 3:

(22) The operator can use said alignment device 26 to influence the movement of the backgauge 9 when manipulating the alignment device 26.

(23) If, in contrast to the illustration according to FIG. 2, the pressing bar 7 is in its raised position, the operator can, when the controller of the alignment device 26 is activated, avoid creating the exact movement of the backgauge 9 by turning the hand wheel 23 of the cutting machine 1, but rather said operator is able to effect this by operating the operator control elements 38 to 40 of the alignment device 26. During this procedure, the operator can look at the stack and, in the process, control the alignment device 26 in such a way that approximate, rapid advance of the backgauge 9 is initiated initially by controlling the operator control element 40, and then the rapid forward movement is performed by operating the operator control element 38, with the alignment device 26, which is supported on the table 4 and possibly is manipulated by the operator, as illustrated in respect of FIG. 2 and in respect of FIG. 3, bearing flat against the stack 28 on that side of said stack which is averted from the rake section 10. If the cutting marking on the top sheet of the stack is at a relatively short distance from the cutting plane, the operator releases the operator control element 38 and presses the operator control element 40 in order to switch said operator control element for slow movement. When the operator control element 38 is subsequently pressed again, the backgauge 9 will move further forward at a low speed, until the operator releases the operator control element 38 when the desired position is reached.

(24) Since the operator does not have to hold the cutting machine 1 in this portion of the method, he can, for all intents and purposes, as illustrated in respect of FIG. 3, use one hand to move the alignment device 26, which is provided according to the invention and which has the electrical components, and use the other hand to move a conventional alignment device 26 which then serves to align the material, and therefore has no electrical components. This allows, with two-handed operation, both the cutting machine 1 to be actuated by means of the alignment device 26 and also the stack to also be aligned on two adjoining sides by means of the alignment device 26 and the conventional guide gauge 43.

(25) The dotted-and-dashed line in FIG. 2, which is denoted by the reference numeral 44, shows the cutting plane of the cutting blade 6, as seen perpendicular to the plane of the drawing sheet.

(26) In FIG. 3, the topmost sheet of the stack 28 is provided on its front, left-hand side with a printed barcode 45 which can be evaluated by means of a barcode scanner of the alignment device 26. Data which is evaluated by the scanner can be displayed either on a display of the alignment device 26 or on the operator control and information display 11 of the cutting machine 1, or even processed by the machine controller for automated processing of the stack 28.

(27) FIGS. 6 and 7 show a second exemplary embodiment of the alignment device 26. Said alignment device is designed substantially in accordance with the exemplary embodiment according to FIG. 4 in respect of the plates 29, 31 and the grip part 33. The alignment device 26 according to FIGS. 6 and 7 exhibits, on one side of the alignment device 26, next to the grip part 23, a box 46 in which not only the electronic controller 41 of the alignment device 26 but also a barcode scanner are accommodated, it being possible for the scanner beam from said barcode scanner to pass through a rectangular passage opening 47 in the plate 29. On the other side of the grip part 33, a connection 48 with three sockets 49 for inserting mobile data memories is provided with the plate 29. Measurement data or else software updates relating to the alignment device 26 which has the electronic components is/are stored on said data memories, for example.

(28) Two operator control elements 38 and 39 for advancing and returning the backgauge 9 are arranged in the grip part, and furthermore an actuating wheel 50 is arranged between these two operator control elements 38, 39, wherein said actuating wheel is connected to electrical components of the electrical controller 41 in such a way that a movement speed of the backgauge 9 can be varied, taking into account the operation, by the operator control elements 38 and 39, by virtue of large or smaller rotation angles of the actuating wheel 50.

(29) The third exemplary embodiment according to FIGS. 8 and 9 differs from the basic design of the alignment device 26 according to FIGS. 6 and 7 in respect of plate 29, plate 31, part 33 with grip recess 34, and also the operator control elements 38, 39 and the actuating wheel 50 in that the plate 29 has a touchscreen 51 on one side of the grip part 33, on the top of the plate 29, said touchscreen being connected to the electrical controller 51 and it being possible to manually input data by means of said touchscreen and it being possible to display data on said touchscreen.

(30) Furthermore, said alignment device 26 has, on the other side of the grip part 33, on the bottom of the plate 29, measuring means 52 for measuring a movement path of the alignment device 26, which is supported on the table 4, relative to the table 4. These measuring means can have a wheel which runs on the table 4 and of which the rotary movement is a reference for the distance covered by means of the alignment device 26. Furthermore, the alignment device 26 has, in the region of the plate 29, on that side of said plate which is averted from the touchscreen 51, a measuring means 53 for ascertaining a force which acts on said measuring means. When the alignment device 26 is placed against the stack 28 by way of the plate 31, said stack acts on the measuring means 53 which project somewhat beyond the surface 32, and therefore said measuring means can absorb the force with which the stack presses against the measuring means 53.

(31) The described cutting system 25 permits an extremely wide variety of modifications, in particular in respect of the alignment device 26 and actuation of the cutting machine 1 by means of the alignment device 26 or actuation of the alignment device 26 by means of the cutting machine 1.

(32) By way of example, the alignment device 26 can also have operator control elements which effect the function of the foot pedal 24 for executing the cutting indication by lowering the pressing bar 7 into a position slightly above the stack 28 which is to be cut. It is therefore not necessary for the operator to operate the foot pedal 24. It is therefore possible to effect said function by operating one or more operator control elements of the alignment device 26, without looking away from the region of interest of the stack 28. The function of the changing pressing pressure of the pressing bar 7 can also be integrated into the alignment device 26.
