Definitions

  • This invention relates to machines for cutting card, board and the like materials. Such machines are used, for example, by picture framers, designers, artists, photographers and the like. Among the uses of such machines are the reduction of large sheets of card to smaller sizes and the cutting of apertures therein, whether with bevelled or square-cut edges. Machines of this kind will be referred to, herein and in the claims, as cutting machines of the kind set forth. It is to be understood that this definition is not to be limited to the provision of bevel cutting or other features which may be needed for particular applications falling within the uses mentioned above. Machines of the kind set forth above may include a base board to support card, board and the like to be cut, together with a clamp bar extending across the base board to clamp the materials to be cut.
  • a cutter head may be mounted on the cutter head for lengthwise sliding movement with respect thereto to cut the materials.
  • Some aspects of the invention also relate to other material treatment or positioning or measurement machines, particularly those having an extruded slideway on which a slider or slidehead is slidable.
  • a further aspect of the invention relates to providing improvements in relation to the system disclosed in our prior patents concerning calibration of the stop and other gauge systems for the cutter, whereby the cutter is set for a pre-determined location and length of cut in relation to the sheet material to be cut.
  • An object of a first aspect of the present invention is to provide a cutting machine of the kind set forth providing improvements in relation to one or more of the aspects thereof discussed above concerning guidance and support for the cutter head, and/or improvements generally therein.
  • co-operating guide means on the clamp bar and the cutter comprising a lengthwise-extending guideway on the clamp bar and a guide member on the cutter head.
  • the guideway and guide member have complementary tapering profiles providing bearing surfaces.
  • These tapering surfaces on the guideway and the guide member comprise at least one flexible bearing element mounted so that at least a portion thereof is capable of being flexed towards its co-operating bearing surface for adjustment purposes.
  • the portion which is capable of being flexed comprises an end portion of the bearing element, indeed both end portions of the bearing element are flexible and the portion therebetween is fixedly mounted.
  • the bearing element is formed of a polymeric material whereby its flexibility enables it to provide a corresponding adjustment function in a very sinmple manner by means merely of the provision of adjustment screws.
  • the feature of the flexibility of the bearing element arising from its polymeric construction and its associated fixed mounting at a location spaced from the flexible portion enables the bearing element to provide for very simple adjustment of the bearing itself merely by provision of corresponding adjustment screws, while nevertheless offering a highly; effective bearing system capable of accommodating tolerances introduced by the extrusion manufacturing process in combination with the provision of very adequate bearing surface areas for relatively long bearing life.
  • cooperating guide means on the clamp bar and the cutter head comprising a lengthwise extending guideway on the clamp bar and a guide member on the cutter head, the guideway and the guide member having complementary profiles.
  • These profiles provide lateral guidance of the cutter head and are disposed so that loading the cutter head in a cutting direction tends to caused reduced loading of the bearing surfaces provided by the complementary tapering profiles.
  • the downward hand loading of the cutter head by the user is in a direction such that the tapering profiles are urged in a direction reducing their face-to-face loading.
  • the main bearing surface resisting the downward loading on the cutter head is, in the embodiment, provided by simply face-to-face contact of generally vertically disposed bearing surfaces directed directly below.
  • the tapering and laterally-guiding bearing surfaces are disposed on opposite sides of the slideway.
  • adjustment means to adjust at least one of the tapered bearing surfaces to adjust the loading of that bearing surface.
  • simply screw threaded adjustment means is provided for this purpose.
  • an additional feature of the described embodiments relates to the features whereby the cutter head lateral guidance system is able to accommodate and tolerate those irregularities in linearity of the extruded clamp bar which arise from its extrusion-type manufacture.
  • the bearing elements for providing lateral guidance of the cutter head are formed with a relieved region separating lengthwise-spaced bearing areas so that continuous sliding bearing contact with the clamp bar (or guideway) is not required.
  • the relieved region is able to accommodate the non-uniform portion of the clamp bar whereby the latter passes smoothly between the bearing areas and, again uniformity of the cutting line is ensured with an absence of discontinuities.
  • a further feature of the embodiments concerns a simple method for adjustment of the bearing system lateral guidance for the cutter head. It is only necessary to adjust the bearing element at one side of the guideway and not at both sides.
  • that bearing element has attachment means securing it to the cutter head in its central region, while leaving its end regions (which actually make sliding contact with the guideway, at each side of the central relieved region) free to be adjusted by simple screw threaded means.
  • the relevant one of the bearing elements is centrally mounted in its relieved region and is provided with simple screw threaded adjusters for its end bearing regions, which adjust and readily take up the level of adjustment needed under cutting loads incurred during use.
  • the generally truncated triangular profile of the bearing elements (whereby they have parallel base and upper surfaces) enables them to provide both the lateral guidance and the vertical load bearing functions simultaneously at the requisite laterally spaced locations, thereby achieving a further simplification in function and construction.
  • a further aspect of the invention provides a cutting machine of the kind set forth as defined in claims 28 to 32 of the accompanying claims, and in embodiments of this aspect of the invention described below there are provided relieved portions in the tapering bearing surfaces of the guideway on the clamp bar and guide member on the cutter head whereby the relieved portion is capable of accommodating a degree of mismatch of the tapered profiles arising from, for example, tolerances introduced during manufacture by extrusion.
  • the relieved portion allows a degree of, effectively, angular movement of the main sliding sub-assemblies of the apparatus whereby bearing surfaces which (due to angular mismatch) might otherwise make effectively almost line contact can come into proper face-to-face contact across at least a substantial portion of their intended operating width.
  • a calibration device for a stop or other gauge on the cutting machine where an indicator and a measurement scale adjust relative to each other so as to adjustably indicate the value of a dimension selected for the cutting machine.
  • Manual adjustment means is adapted to adjust the relative positions of the indicator and the scale to permit selective compensation or offset for detected errors in the resultant cut dimension produced by the cutting machine, and the calibration device comprises calibration indication means whereby a measure is provided of the extent of the compensation or offset provided frcm a predetermined or nominal zero position.
  • the arrangement is such that the adjustment device which effects calibration movements is arranged to effect simultaneous adjusting movement both of a calibration extent-indicating member and of a corresponding calibration member for the measurement scale.
  • These are formed as a common movable structure having two limbs disposed generally parallel to each other and likewise parallel to the calibration and measurement scales.
  • a machine 10 for cutting card, board and like materials as used by picture framers, artists, designers, photographers etc comprises a base board 12 to support the card, board and the like to be cut.
  • a clamp bar 14 extends upon the base board to clamp materials to be cut.
  • Mounting means is provided for the clamp bar and comprises a pair of spaced arms 16, 18 between which the clamp bar is connected.
  • Means is provided for raising and lowering the clamp bar to allow insertion of the materials to be cut.
  • This means permits at least the ends of the arms 16, 18 to be raised and provides a torsion bar 20 interconnecting the ends of the arms 16, 18 for manual lifting by the user, and a pair of support legs not seen in the drawings, whereby the bar 20 can be held in a raised position for inserting of card under the clamp bar.
  • the arms of 16, 18 comprise leaf springs 22, 24 which permit the tension bar 20 to be raised by simple bending of the springs. This provides a very durable construction.
  • a cutter head 26 is mounted on clamp bar 14 for lengthwise sliding movement with respect thereto, to cut the card or other materials. Stop means, not shown in detail, is provided for a user accurately to cut card to size and to cut apertures, for example aperture 28 shown in card 30, during use.
  • Fig 3 shows cutter head 26 in use, with the hand 32 of the user actuating, by means of thumb and index finger a pivotal cutter element 34 having a blade 36, pivotal movement of an axe is generally at right angles to the surface 38 as seen in Fig 2 enables the user to bring head 36 in and out of its cutting position.
  • clamp bar 14 is shown together with a sliding block 40 forming part of cutter head 26.
  • Block 40 provides a mount forming part of element 34 carrying blade 36.
  • Blade 36 engages the material to e cut by projecting slightly beyond the edge 42 of clamp bar 14.
  • Blade 36 and cutter element 34 are not shown in Fig 2.
  • Clamp bar 14 is formed with recesses 44 and 46 to mount scales for measurement purposes during use.
  • Profiled recesses 48, 50 and 52 in sliding block 40 provide mounting for further structures of the cutting machine not relevant for purposes.
  • cutter head 26 is located on clamp bar 14 by means of a sliding locater 54 mounted on block 40 by means of a fastener 56 and an intermediate spring element 58.
  • Locater 54 is generally of upwardly tapering form and is received in a corresponding channel 56 formed in clamp bar 14. Fastener 56 is adjusted so that the locater freely slides in channel 56.
  • guide means on the clamp bar and on the cutter head comprising a lengthwise extending guideway on the clamp bar and a guide member on the cutter head, the guideway and the guide member having complementary tapering profiles.
  • guideway 60 is in the form of a wedge shaped slot formed in clamp bar 14
  • guide member 62 is in the form of a projecting wedge member received in the slot.
  • interengaging sliding support surfaces 64, 66 which serve also to resist downwardly directed loads in use.
  • the locater 54 is adjusted to provide sliding movement while adequately locating cutter head 26. After that no further adjustment is needed.
  • Surfaces 64, 66 and the engaging surfaces of the guideway and guide member 60 and 62 are provided with a low friction material such as UHMW Polyfine to promote free sliding movement.
  • machine 100 for cutting card, board and like materials comprises a clamp bar 102 having a cutter head 104 mounted thereon and corresponding to cutter head 26.
  • cutter head 104 mounted thereon and corresponding to cutter head 26.
  • Details of the construction of cutter head 104 from cutter head 26 differ in respects which are unimportant for the purpose of the present invention and will therefore not be described.
  • the important differences of the present embodiment from cutter lead 26 relate to the systems provided for location and for lengthwise sliding movement and lateral guidance and for the provision of means to slidingly resist vertical and related loads.
  • cutter head 26 is located with respect to clamp bar 14 by sliding locater 54 mounted on block 40. Lateral guidance is provided by complementary tapering profiles provided on guideway 60 in the form of a wedge shaped slot, and a corresponding guide member 62 in the form of a projecting wedge member received in the slot. Bearing surfaces 64 and 66 slidingly support the cutter head.
  • the entire system for providing not only location but also lateral guidance and bearing support against downward loads during use is provided by a guideway 106 on clamp bar 102 and cooperating bearing elements 108, 110 provided on cutter head 104.
  • guideway 106 has outwardly facing and upwardly-diverging guideway surfaces 112.
  • Bearing elements 108, 110 have respective complementary, inwardly-facing and upwardly-diverging bearing surfaces indicated in Fig 5 and 114 and 116 but which are more fully described below with reference to Fig 6.
  • Bearing elements 108, 110 are received in correspondingly-rectangularly profiled recesses formed in cutter head 104 so that their bearing surfaces 114 and 116 are placed for sliding engagement with the corresponding bearing surfaces 112 of clamp bar 102.
  • the bearing elements are secured in position by fasteners 118 having heads 120 received in countersunk apertures 122.
  • Fasteners 118 have threaded shanks 134 which screw-threadily cooperate with threaded bores provided at the inner portion of apertures 122.
  • Bearing elements 118, 110 extend lengthwise the full lengthwise extent cutter head of 104 and likewise the recesses in which they are mounted. These recesses are provided at the inner side faces of a generally channel-shaped portion 126 of the cutter head defined by flanges 128 provided on the cutter head.
  • Fig 4A shows on a larger scale a detail of the construction of the guideway 106 which can also be seen in Fig 104, notably the provision of the relieved portions 112A in bearing surfaces 112 to accommodate a degree of mismatch of the tapered profile arising from, for example, tolerances introduced during manfacture by extrusion of the guideway.
  • the relieved portions extend across only a portion of the width of the relevant bearing surfaces, such portions being less than half of that width and indeed slightly less than one quarter thereof. The relieved portions permit the toleration of more mismatch than otherwise would be the case without an unacceptable loss of bearing surface area.
  • the bearing element material itself may be chosen according to the specific characteristics required and according to the predispositions of the user.
  • a typical example might be a UHM (Ultra high molecular weight) Polyolefin, or PTFE or a derivative thereof or any other polymer having suitable friction and wear characterises whether with or without a filler or other materials.
  • each of the bearing elements 108, 110 has a central relieved portion 132 which is relieved to the extent of a few millimetres in depth in order to ensure that the end bearing regions 134 provide the entire inclined and inwardly facing bearing surfaces for the bearing element.
  • Each of the bearing elements is similarly constructed in this regard.
  • Fig 6 does not show the generally wedge-shaped profile of the bearing element very clearly. This can be readily seen in Figs 4 and 5.
  • Apertures 122 are formed in the central relieved region 132.
  • the bearing elements are mounted and supported in their central region and their bearing regions are capable of being deflected for bearing adjustment reasons as explained below.
  • cutter head 104 is provided with additional screw threaded apertures 136 to receive corresponding threaded fasteners 138 for adjustment purposes.
  • the adjusters 138 have suitable driving formations such as slots or sockets whereby there can be threaded inwards or outwards for engagement of their inner ends (not shown) with the rear side of end bearing regions 134 of bearing elements 108, 110 so as to adjust these towards and away from the corresponding tapering services 122 on guideway 106. Provisions for such adjustment is only made at one side of cutter head 104 namely with bearing element 108, since this is sufficient to make all required adjustments.
  • the clearances of bearing element 118,110 are adjusted by means of fasteners 138 in order to provide free running but backlash-free guided sliding movement of the cutter head.
  • an end stop device in the form of a start-of-cut assembly suitable for use with a cutting machine of the kind shown in Fig 1 of the drawings.
  • Such an assembly defines the location at which the cutter head is caused to stop in its lengthwise travel along the guideway at that end of its travel which represents the start of cut.
  • the assembly is slidably mounted on the clamp bar 14, (see Fig 1).
  • the assembly would be mounted at a location to the right of cutter head 26 in Fig 1 so that the cutting travel of the cutter head extends from the stop assembly in a leftwards and downwards direction, as seen in Fig 1, towards the other stop which is indicated at 200.
  • Stop assembly 202 of Figs 9 to 13 incorporates a calibration device 204 which may also be used in the other stop 200, and likewise in other adjustable measurement devices on the cutting machine 10 including the so-called mat guide 206 (with sliding adjusters 208,210) and the limit stop 212 for presetting mat sizes.
  • the calibration device 202 is applicable to the several identified locations in cutting machine 10 at which the position of a stop device or like mechanical element depends for the accuracy of its setting on user-perceived mechanical setting data on a main setting scale, the interpretation of which will vary, to some extent from one user to another. Accordingly, by provision of a resettable calibration device the calibration setting which any particular user finds convenient and which leads to accurate cutting can be readily achieved and returned-to in accordance with the features to be described below.
  • calibration device 204 comprises a stop member in the form of an arm 214 projecting laterally from a slidable caliper 216 received on a lengthwise extending scale 218 carried on clamp bar 14 (not shown in Figs 9 to 13).
  • An indicator 220 mounted on caliper 216 co-operates with measurement scale 218 to indicate the adjusted position of caliper 216.
  • a setting knob 222 having a screw-threaded shank 224 co-operates with scale 218 and caliper 216 to fix the caliper in a selected adjusted position.
  • Arm 214 has a leaf-spring-mounted extension 226 having a projecting contact 228 to rest on the upper surface of the sheet material being cut.
  • Calibration device 204 further comprises manual adjustment means 230 adapted to adjust the relative positions of indicator 220 and measurement scale 218 to permit selective compensation or offset for detecting errors in the resultant cut dimension produced by the cutting machine.
  • Calibration indication means 232 is provided to indicate the extent of calibration selected from a pre-determined nominally zero position.
  • Calibration indication means 232 comprises a calibration scale 234 and an associated indicator 236.
  • calibration scale 234 and indicators 220 for measurement scale 218 are formed as a one-piece generally U-shaped structure having corresponding twin limbs which is slidably received in corresponding grooves seen best in Fig 10 whereby it is lengthwise-adjustable at a location above measurement scale 218 and in a direction generally parallel thereto.
  • An adjustment knob 238 having a corresponding screw-threaded shank 240 on which is received a coiled compression spring 242 serves to provide an adjustment function for indicator 220 and calibration scale 234.
  • Indicia 244 and an associated adjustment direction arrow 246 serve no identify the direction of rotation of knob 238 for positive or negative calibration adjustment from a nominal zero position seen in Fig 9.
  • this aspect of the present invention is not limited to use in relation to devices involving a cut-limiting stop but may, for example, be used for calibration of the setting scale for other dimensional aspects of the cutting procedure including the positioning of board or other materials to be cut with reference to the apparatus as such.
