Definitions

  • the present invention relates to a machine for securing clips along one long edge of metal roofing sheets, in accordance with the preamble of Claim 1.
  • the roofing sheets present along this one long edge of the sheet an edge part or web which is bent upwards to an angle of about 90° and the free lip part of which is bent inwards over the main surface of the sheet at an angle of about 90°.
  • the clips to be fitted onto the roofing sheet have a generally flat web which is provided on one side thereof, at its bottom end, a base flange which is angled at abut 90° to said web and which has at its top end a tongue which is bent down towards the other side of the web.
  • roofing sheets have earlier been fitted by manually anchoring the sheets manually to an underlying support surface with the aid of clips, which are connected manually to said one long edge of the sheet at respective anchoring locations.
  • roofing sheets are normally anchored in position with the aid of two types of clips, a slide clip and a fixed clip.
  • fitting clips to roof sheets mechanically is that the permitted distance between mutually adjacent clips can be selected in accordance with current regulations and standards, thereby enabling the number of clips used to be kept to a minimum while keeping to the stipulated clip spacing.
  • the clips are positioned at shorter distances therebetween than is necessary, for the sake of safety.
  • the object of the present invention is to provide a machine for mechanically fitting clips along one long edge of metal roofing sheets, so that the sheets can be anchored to the roof structure quickly and in a relatively simple fashion.
  • the machine includes means for moving the roofing sheets in their longitudinal directions, a clip securing head, a clip magazine, means for transferring clips singly from the magazine to the head, means for driving the head together with a clip carried thereby into engagement with the edge of the roofing sheet at predetermined positions therealong, such as to secure a clip to the sheet in respective positions, wherein the head includes gripping means which grip around the bent lip part of the clip and clamps the bent end-part of the roofing sheet flange, and a punch or die means which is carried by the head and which functions to bring the bent part of the clip fitted to the edge of the roofing sheet into abutment with the raised edge of said sheet.
  • the clamping means may include a rammer means which is connected to the punch.
  • the head is also provided with a counter-pressure means, or anvil means, for coaction with the rammer means.
  • This counter-pressure means may have the form of a lever which is pivotally mounted on the head.
  • the machine may also include an upper lever, which is also pivotally mounted on the head.
  • a power ram is connected between the respective one ends of the two lever arms, such as to drive the rammer and the counter-pressure means towards one another when securing a clip.
  • the pivotal movement of the lower lever on the head, which lever forms the counter-pressure means, is limited and the machine may include adjusting means for adjusting the extent of lever movement.
  • the machine also includes means for driving the head in the transverse direction of the roofing sheet, so as to enable the counter-pressure means to be moved in beneath the rim part of the sheet and, in connection therewith, to hook the bent part of the clip firmly onto the rim of the roofing sheet.
  • the head is preferably moved in said transverse direction to the selected positions along the long edge of the roofing sheet at which a clip is to be fitted.
  • the machine is also preferably provided with a holder by means of which the base part of the clip can be held temporarily adjacent the punch.
  • the holder preferably includes an arm which is spring biased towards a closed position and which defines a clip insertion slot together with the punch.
  • the magazine may include a stack magazine, in which the clips are positioned with their respective webs generally horizontal and their bases facing upwards, the lowermost clips in the magazine being ejected therefrom, by means of a piston-cylinder device in a direction defined by the bending line of the base part.
  • the bent end-part of the clip will then rest on the counter-pressure means with the base of the clip positioned in the punch slot.
  • the piston-cylinder device is activated, the punch and the rammer are driven downwards and the counter-pressure device is pivoted upwards into abutment with the bent end-part of the clip.
  • the clip is bent and the bent-part of the clip is clamped or squeezed securely to the lip or edge of the roofing sheet.
  • the clamping means is opened by returning the piston-cylinder device to its starting position, whereafter the head can be moved laterally and the roofing sheet can be moved in its longitudinal direction and a further clip inserted in the clamping means, whereafter the described working cycle can be repeated.
  • FIG. 1 Shown in Figure 1 is a conveyor 1 which carries a metal roofing sheet or panel 2.
  • One long edge of the roofing sheet has an edge-part 21 which is bent up at an angle of about 90° to form a flange and the free lip-part 22 of the flange is bent in over the main surface 23 of the sheet 2, so as to be substantially parallel therewith.
  • the conveyor 1 is provided with drive means 11, such as to convey the roofing sheet 2 in a direction perpendicular to the plane of the Figure.
  • the machine includes a head 3 which is moved by drive means 31 in the direction of the arrow 3, parallel with the main surface 23 of the sheet 2, at right angles to the longitudinal axis of said sheet.
  • an upper two-arm lever 41 Pivotally mounted on an upper bearing or journal 4 on the head 3 is an upper two-arm lever 41, whose one arm is activated by a vertically positioned pneumatic piston-cylinder device 5.
  • the other arm 43 of the lever 41 is connected to a clip-bending punch 6 provided with a fixed clamping or crimping jaw 61.
  • the punch 6 is guided for linear movement on the head 3, substantially in a vertical direction.
  • a pivot journal 7 which carries a lower two-arm lever 71, whose one arm 72 is connected to the lower end of the piston-cylinder device 5.
  • the other arm 73 of the lever 71 forms a counter-pressure means 75 for coaction with the clamping jaw 61.
  • the lever 71 also has a substantially vertical arm 76, whose one side coacts with an adjustable stop screw 31 provided in the head 3, and whose other side 77 is able to coact with an abutment surface 28 on the head 3.
  • the head 3 also carries a clamping arm 62 which is pivot-ally mounted on a journal bearing 63 and biased towards a closed position by means of springs 64.
  • the arm 62 defines, together with the punch 6, a clamping slot 65 which receives the base flange of a clip to be fitted onto the edge flange 22 of the roofing sheet with the aid of the machine.
  • the bearing 45 located between the arm 43 of the upper lever and the punch 66 may exhibit play in the longitudinal direction of the lever 41 so as to allow the arm 43 to pivot around the journal 4 in spite of the fact that the punch 6 is guided for linear movement of the guide 6.
  • a slide clip 8 which comprises a generally flat web 81, the bottom end of which has on one side thereof a base flange 82 which is angled from the web at substantially 90° and which is provided with screw-receiving holes 83.
  • the upper part of the web 81 has provided therein an opening 84 which facilitates bending of the upper web part.
  • the upper part of the web 81 is also provided with a bent or folded hooked part 85 on the opposite side of said web to the base flange 82.
  • Figure 2 illustrates the initial starting position of a working operation.
  • the head 3 is moved to the right in Figure 1 by means of the drive means 31, whereby the bent or hooked part 85 of the clip 81 will grip around the lippart 22 of the roofing sheet 2, as shown in Figure 3.
  • the piston-cylinder device 5 is then activated, whereby the lever 71 will swing to the right, causing the counter-pressure device 25 to move upwards towards the clip and the lip-part 22.
  • the lever 41 is swung by the piston-cylinder device 5 so as to cove the punch 6 downwards in its linear guide means, thereby clamping the clip part 85 firmly on the lip-part 22 of the roofing sheet as a result of downward movement of the clamping jaw 61 of the punch 6 and its force-coaction with the counter-pressure device 75.
  • the nose-part 66 of the punch bends the web part 81 of the clip around the edge of the roofing sheet formed by the flange 21 and the lip 22.
  • the extent to which the base part 82 of the clip is held firm by the clamping arm 62 is controlled by the wedge surfaces 67, 68, so that the clamping arm 62 will release its hold on the base part 82 in conjunction with the bending operation.
  • the base part 82 is provided with holes 83 and the clamping arm 62 of the illustrated embodiment is provided with a ball which is received on one of the holes 83.
  • the punch 6 may be provided with a recess corresponding to said ball.
  • FIG. 7 illustrates schematically a stack magazine 9 for clips 8.
  • the magazine 9 includes a container part 91 which receives clips 8 with their respective webs 81 positioned essentially horizontally and the base parts 82 thereof facing upwards.
  • the bottom of the container part 91 is terminated with a stop plate 92, such that the lowermost clip 8 can be moved in the direction 86 defined by the bending line between the clip web 81 and the clip base 82, the bottom lip or edge of the container part 91 being adapted to the contours of the clip and spaced above the stop plate 92 so as to permit only one clip 8 to be ejected from the magazine at any one time.
  • the magazine 9 is positioned such that the base part 82 of the clip 8 will be aligned with the corresponding slot or gap 65 between the punch 6 and its clamping arm 62, and such that the hooked part 85 of the clip is aligned with the nearest space above the counter-pressure device 75, so that the clip 8 can be transferred from the magazine 9 to its intended position in the clamping device according to Figure 1, simply by being moved in the direction 86 by means, e.g., of a ram 100, the piston rod 101 of which moves in the direction 86 and acts on the exposed, lowermost clip 8 in the magazine, as shown schematically in Figure 6.
