Definitions

  • the present invention relates to a device for rotating a mattress on the working table of a hemming machine.
  • Hemming machines have also been proposed which comprise devices for rotating the mattress with respect to the sewing machine.
  • Devices of this kind are known from European patent application publication no. 264618 in the name of the same Applicant, from European patent no. 330.285, from German patent application publication no. 3521559, and from French patent no. 1,567,893.
  • the mattress slides on a table during rotation, and therefore friction forces arise which make the rotation angle inaccurate.
  • Known devices furthermore do not solve the problem of turning over the mattress in order to perform the hem on the other side.
  • the technical aim of the present invention is to provide a device that allows to obviate these drawbacks, so that the orientation of the mattress with respect to a hemming machine becomes accurate and so as to mechanize the mattress turning-over operations, which are currently performed by hand by the same operator who controls the hemming machine, with great effort and waste of time.
  • an object of the present invention is to provide a device that is reliable in operation and versatile in use in relation to the various shapes and dimensions of the mattresses.
  • the device comprises a frame composed of a post 1 having a square cross-section and rising to the side of a transport and working table 2 constituted by rows of mutually parallel free rollers 3.
  • the rollers 3 are very close to each other but are not in mutual contact, so that they can rotate freely in both directions A and B and allow the handling of a mattress 4 placed thereon.
  • a carriage 5 can be positioned on the post 1, and a bracket 6 cantilevers out from said carriage and supports a hemming machine 7 comprising a conventional sewing machine equipped with means for guiding a tape that is meant to be stitched so as to cover the stitch lines joining the upper and lower faces 8 and 9 of the mattress 4 to the perimetric band 10.
  • a hemming machine 7 comprising a conventional sewing machine equipped with means for guiding a tape that is meant to be stitched so as to cover the stitch lines joining the upper and lower faces 8 and 9 of the mattress 4 to the perimetric band 10.
  • the inclination of the bracket 6 is adjustable to allow to orientate the hemming machine 7 at an angle allowing diagonal stitching suitable to form a rounded ridge 11 surrounding the upper and lower faces of the mattress.
  • An arm 12 protrudes from the top of the post 1 and supports, at its end, a sleeve 13 the axis C of which is vertical and passes at the region where the hemming machine forms its stitch.
  • a substantially bracket-like vertically hinged structure 14 is rotatably supported in the sleeve 13 and is composed of an upright 15, rigidly coupled, by means of two arms 16 and 17, to a pivot which is rotatable within the sleeve 13, and of a beam 18 that cantilevers out from the lower end of the upright 15 and is supported by a brace 19 that joins the beam 18 to the top of the upright 15.
  • a pivot 20 is furthermore mounted at the top of the upright so that it can rotate about a vertical axis; a diametrical female thread 21 is formed in said pivot and is engaged by a threaded rod 22.
  • the threaded rod 22 is driven by a motor 23 installed on a platform 24 that is laterally rigidly coupled to the arm 13.
  • the structure 14 is completed by a rectangular frame 24a fixed to the beam 18 proximate to the upright 12 and at the front of which two pneumatic jacks 25 and 26 are applied vertically; the stems of said jacks protrude downward and support respective pads 27 and 28.
  • Two guiding bushes for a pair of vertical parallel rods 29 and 30 are installed in the beam 18; said rods rise from a bar 31 that lies below the beam 18 and acts as a pusher to make the mattress 4 rotate about the axis C.
  • a horizontal plate 32 protrudes from the upper edge of the bar 31 on the working table 2 and is meant to rest on the upper face of the mattress when the bar 31 is in the lowered condition and in abutment against a perimetric side, that is to say, in contact with the band 10.
  • the bar 31 can be raised and lowered on the table 2 by means of a pair of jacks 33 and 34, in which the cylinders are mounted on the beam 18 and the stems are rigidly coupled to the bar 31.
  • the described device is completed by a series of vertical rollers 35 freely mounted on the member 35a that delimits the working table 2 on the side of the hemming machine.
  • the vertical rollers 35 form a vertical wall for guiding the mattress 8 during the hemming of its longitudinal and transverse sides.
  • the device operates as follows. In order to hem the longitudinal and transverse sides of the mattress, the bar 31 is raised with respect to the working table 2 and is co-planar with respect to the vertical rollers 35.
  • the mattress 4 after being transferred onto the rollers 3 of the table 2, is positioned so that its side to be hemmed (for example the transverse one, as in figure 2) abuts against the rollers 35, and is then made to advance in the direction A through the hemming machine 6 to form the hem along the corner formed by the band 10 with respect to the upper face.
  • its side to be hemmed for example the transverse one, as in figure 2
  • the jacks 25 and 26 are activated and, by descending, lock the mattress 4 on the roller table 2.
  • the jacks 33 and 34 are actuated so as to move the bar 31 into a position that is adjacent to the band 10 of the freshly hemmed side and so as to make the plate 32 rest on the upper face of the mattress.
  • the height of the bar 31 and of the rollers 35 is such as to prevent mutual contacts when the bar 31 is in lowered position.
  • the motor 23 is activated and, by means of the rod 22, acts on the structure 14, turning it by 90° about the axis C.
  • the mattress 4 is orientated so that its longitudinal side is adjacent to the vertical rollers 35.
  • the rotation axis C of the structure 14 passes on the inside of the peripheral edge of the mattress proximate to the hem.
  • the hem at the corners of the mattress can follow a circular arc-like path that allows to form rounded corners.
  • rollers 2 since they are freely rotatable in both directions, they considerably reduce the resistance of the mattress to rotation. It is furthermore possible to interpose between the rollers 2 means that turn the mattress over, after one face thereof has been hemmed, in order to complete the hemming of the opposite face.
  • rollers 3 of the working table 2 are arranged so as to allow to arrange between them two frames 36 and 37 that can be raised by jacks (not shown, but easily imaginable) from a position in which they are co-planar with respect to the table 2 into an opposite position, in which they substantially form a V with respect to the table 2 (see figure 5).
  • the frames 36 and 37 are constituted by respective arms 38 that are articulated within the roller table 3 and extend in the opposite directions A and B, respectively, between the rollers that form the various rows and are appropriately spaced so as to form a seat for accommodating the arms 38.
  • Slats 39 extend at right angles from each arm 38 in opposite directions and are accommodated between the various rows of rollers 3.
  • a mattress is turned over by placing it on one frame, for example on the frame 36, and by then rotating said frame about its fulcrum so that the mattress 4, after moving beyond the vertical position due to inertia, rests against the other frame 37, raised beforehand in front of the frame 36 so as to assume an inclined position. Once the mattress rests on the frame 37, said frame is lowered to deposit the mattress in overturned position on the roller surface 3.
  • a preferred embodiment provides that the rollers 3 tangentially contact lower belts in engagement with driving pulleys, or that the rollers 3 have cylindrical interior bearing surfaces enclosing respective driving shafts, so that rotation of said pulleys or shafts causes rotation of said rollers.
