Abstract
Description
- The present invention relates to a device for rotating a mattress on the working table of a hemming machine.
- It is known that it is necessary to rotate by an angle of 90o a mattress on the working and transport table of a hemming machine in order to perform operations at the corners in passing from the hemming of the transverse sides to the hemming of the longitudinal sides.
- In hemming machines provided with a stationary sewing machine, the mattress is currently rotated mostly by hand.
- 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. In known devices, 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.
- Within the scope of this aim, 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.
- This aim and this object are achieved with a device whose characteristics are defined in the claims.
- Further characteristics of the present invention will become apparent from the following description on the basis of the accompanying drawings, wherein:
- figure 1 is a perspective view of the device, applied to a mattress hemming machine;
- figures 2 and 3 are perspective views of the device, taken from a different viewing angle, with the pusher in raised and lowered position respectively;
- figure 4 is a plan view of a variation of the device; and figure 5 is a lateral elevation view of the variation
- of figure 4.
- With reference to figures 1 to 3, 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 parallelfree rollers 3. Therollers 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 amattress 4 placed thereon. - A carriage 5 can be positioned on the
post 1, and abracket 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 andlower faces 8 and 9 of themattress 4 to theperimetric 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 thepost 1 and supports, at its end, asleeve 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 thesleeve 13 and is composed of an upright 15, rigidly coupled, by means of twoarms sleeve 13, and of abeam 18 that cantilevers out from the lower end of the upright 15 and is supported by abrace 19 that joins thebeam 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 diametricalfemale thread 21 is formed in said pivot and is engaged by a threadedrod 22. - The threaded
rod 22 is driven by amotor 23 installed on aplatform 24 that is laterally rigidly coupled to thearm 13. - The actuation of the threaded
rod 22 in one direction or the other, owing to the off-centered position of thepivot 20 on which therod 22 acts with respect to the axis C, accordingly produces the rotation of thestructure 14 by an angle of substantially 90o. - The
structure 14 is completed by arectangular frame 24a fixed to thebeam 18 proximate to the upright 12 and at the front of which twopneumatic jacks respective pads - Two guiding bushes for a pair of vertical
parallel rods beam 18; said rods rise from abar 31 that lies below thebeam 18 and acts as a pusher to make themattress 4 rotate about the axis C. - A
horizontal plate 32 protrudes from the upper edge of thebar 31 on the working table 2 and is meant to rest on the upper face of the mattress when thebar 31 is in the lowered condition and in abutment against a perimetric side, that is to say, in contact with theband 10. - The
bar 31 can be raised and lowered on the table 2 by means of a pair ofjacks beam 18 and the stems are rigidly coupled to thebar 31. - The described device is completed by a series of
vertical rollers 35 freely mounted on themember 35a that delimits the working table 2 on the side of the hemming machine. Thevertical rollers 35 form a vertical wall for guiding themattress 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 thevertical rollers 35. - The
mattress 4, after being transferred onto therollers 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 therollers 35, and is then made to advance in the direction A through thehemming machine 6 to form the hem along the corner formed by theband 10 with respect to the upper face. - When the trailing corner of the mattress is located at the axis C, the
jacks mattress 4 on the roller table 2. At the same time, thejacks bar 31 into a position that is adjacent to theband 10 of the freshly hemmed side and so as to make theplate 32 rest on the upper face of the mattress. It should be noted that the height of thebar 31 and of therollers 35 is such as to prevent mutual contacts when thebar 31 is in lowered position. - At this point the
motor 23 is activated and, by means of therod 22, acts on thestructure 14, turning it by 90o about the axis C. At the end of this operation, themattress 4 is orientated so that its longitudinal side is adjacent to thevertical rollers 35. - After activating the
jacks pads bar 31, and theplate 32, the longitudinal side is hemmed according to the above described procedures and so are the other sides, until the entire perimeter is completed. - Advantageously, the rotation axis C of the
structure 14 passes on the inside of the peripheral edge of the mattress proximate to the hem. - In this manner, the hem at the corners of the mattress can follow a circular arc-like path that allows to form rounded corners.
- The substantial advantage of the device is provided by the
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 therollers 2 means that turn the mattress over, after one face thereof has been hemmed, in order to complete the hemming of the opposite face. - For this purpose, the
rollers 3 of the working table 2 are arranged so as to allow to arrange between them twoframes 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 byrespective 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 thearms 38. -
Slats 39 extend at right angles from eacharm 38 in opposite directions and are accommodated between the various rows ofrollers 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 themattress 4, after moving beyond the vertical position due to inertia, rests against the other frame 37, raised beforehand in front of theframe 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 theroller surface 3. - A preferred embodiment provides that the
rollers 3 tangentially contact lower belts in engagement with driving pulleys, or that therollers 3 have cylindrical interior bearing surfaces enclosing respective driving shafts, so that rotation of said pulleys or shafts causes rotation of said rollers. - In this way it is possible to assist the advancement of the mattress during sewing and at the same time to permit the rotation of the rollers in the opposite direction when the mattress is swung around its rear corner.
- Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.
