Definitions

  • Appl NOJ 358,840 Means for use in template-controlled sewing devices in which a magnetic roller rolls along the peripheral edge of the template, for preventing a recoil of the rol- 1 Foreign Appllcatlon P710111) Data ler out of the internal corner of the template when May 10, 1972 Germany 2222846 said roller reaches the corner with a proportional high speed.
  • the invention relates to a sewing device which is provided with a support, a sewing machine swingably in a horizontal plane and carried by the support, a template having internal corners, workpiece clamping means above the plate, a supporting body carrying the template and the workpiece clamping means, and a motor driven magnetic roller coaxially with the needle of the sewing machine and bearing against the template.
  • a further object of the invention is to avoid an interruption of the feed of the magnetic roller when it arrives at an internal corner of the template with a high speed.
  • a supporting body which carries the workpiece clamping means and the template and which rests on the support of the sewing device under the own weight and slidable in a horizontal plane.
  • limiting means for the localization of the displaccability of the supporting body on the support and adjustable shock absorbers mounted between the support and the supporting body and acting in a horizontal plane.
  • FIG. I is a top plane view of the sewing device
  • FIG. 2 is a side elevation of the sewing device
  • FIG. 3 is a section taken along line III III of FIG. I
  • FIG. 4 is a section taken along line IV IV of FIG. 1 and FIG. 5 is a perspective view of the supporting body resting on the support of the sewing device, seen from the left and in an enlarged scale.
  • a supporting body 3 comprising an hollow rail 4, a supporting plate 5 for a template 6, a workpiece clamping holder 7 and sliding plates 8.
  • the sliding plates 8 are secured via connecting rails 9 to the hollow rail 4 by means of screws 10.
  • a swivel arm 17 Pivoted to the support 1 is a swivel arm 17 connected via a connecting arm 18 to the supporting arm 15.
  • the supporting arm 15 supporting the sewing machine 14, is guided by a not further shown device in such a manner, that it maintains a nearly vertically extending position with regard to the hollow rail 4 while moving in accordance with the course of the peripheral edge 11 of the template 6.
  • a combined inserting and removing device 19 serving for inserting workpieces 20 consisting of several layers, into the workpiece clamping holder 7, which is located on the supporting plate 5 carried by posts 23, and for removing a workpiece 22 provided with a seam 21, out of the workpiece clamping holder 7.
  • Both ends of the hollow rail 4 of the supporting body 3 are displaceably carried on a plane surface 24 of the side panels 1, while the sliding plates 8 connected to the hollow rail 4 by means of connecting rails 9, rest on an intermediate plate 25 provided with limiting means 26.
  • the latter comprise back stops 28, received with a lateral clearance in circular recesses 29 provided in the sliding plates 8, washers 30 lying on the back stops 28 and having a larger diameter than the circular recesses 29.
  • the washers 30, the back stops 28 and the intermediate plates are screwed to the side panels 1 by means of screws 27 and nuts 31.
  • the back stops 28 have a larger dimension of height than the sliding plates 8, they may be displaced and the entire supporting body as well, within the range limited by the lateral clearance between the back stops 28 and the recesses 29.
  • a shock absorber 32 Arranged to each side panel 1' of the support 1 is a shock absorber 32 composed by a cylindrical bolt 33 (FIG. 3) provided with a threaded end 34 and screwed by means of a nut 35 to the side panels 1', and a lower thrust washer 36 formed with a threaded sleeve 37, an upper thrust washer 38, a pressure spring 39, a washer 40 and adjusting and locking nuts 41.
  • the lower thrust washer 36 received in a recess 42 provided in the intermediate plate 25, is secured against torsion by means of a pin 43 inserted in the side panels 1', and a slot 44 provided in the thrust washer 36.
  • the sliding plate 8 is formed with a recess 45, in which is received the threaded sleeve 37 with a lateral clearance.
  • the pressure spring 39 may be tensioned in order to press both thrust washers 36, 38 against the sliding plate 8 with the required tension.
  • a device for returning the displaced supporting body 3 into its predetermined normal position is provided at the intermediate plates 25 (FIGS. 1, 4 and 5).
  • This device has a double acting air cylinder 47, the piston rod 48 of which is guided in a guide piece 49, which is secured together with the air cylinder 47 to the intermediate plate 25 by means of screws 50.
  • the displaced supporting body 3 After termination of sewing, the displaced supporting body 3 must be returned into its normal position in order that the workpiece to be inserted into the workpiece clamping holder 7 by means of the inserting device 19, is received therein with a seam edge projecting uniformly from the clamping plates of the workpiece clamping holder 7.
  • This normal position is obtained by means of the device for returning 46 by pressurizing the air cylinder 47 causing that the coneshaped centering device 51 is drawn into the coneshaped recess 52 formed in the sliding plate 8 of the supporting body 3, and the supporting body 3 and the workpiece clamping holder 7 are brought into a determined position with regard to the inserting device 19.
  • a sewing device with guided control of a sewing cycle comprising a support means, a link arm, means swingably attaching said link arm to said support means. a supporting arm, a connecting arm pivoted on said link arm and said supporting arm, a template having internal corners, workpiece clamping means above said template, a driven magnetic roller engaged with the peripheral edge of said template, means attaching said magnetic roller on said supporting arm, a sewing machine carried by said supporting arm and having a vertically reciprocating needle coaxially with the said magnetic roller, and a supporting body carrying said workpiece clamping means and said template, shock absorbing means between said supporting body and said supporting means for limiting said supporting body to slide with respect to said support means when said template receives a relatively high shock by having said magnetic roller slam into an internal corner, said shock-absorbing means comprising an upper thrust washer having a bore, a lower thrust washer provided with a threaded sleeve for receiving said upper thrust washer, a spring for pressing said thrust washers against said supporting body, a bolt secured to said support
  • a device as claimed in claim 1 further comprising means for returning said supporting body displaced by said high shock into a predetermined normal position after terminating a sewing cycle.
  • each of said means for returning said supportingbody comprises an air cylinder having a piston rod and fastened to said support means, a cone shaped recess formed in said supporting body and surrounding said piston rod,
  • said limiting means comprises back stops fastened to said support means and received in recesses formed in said supporting body.
