9 Claims.
This invention relates to textile apparatus and.
relates more particularly to textile inspection machines and to improvements in the driving mechanism for moving textile fabrics across the inspection boards of such machines.
Textile inspection machines are widely used for the visual inspection of textile fabrics after they have been subjected to the conventional finishing operations. In employing these machines, the textile fabric is drawn from a supply roll, passed across an inspection board in full view of an operator who examines the textile fabric for defects and is then wound onto a batching roll. During the inspection, it is desirable that the textile fabric be maintained under a controlled and uniform tension and be moved across the inspection board, in either direction, at a controlled and constant speed,
It is an important object of this invention to provide a textile inspection machine which will fulfill the foregoing requirements and which will be especially simple in construction and efficient in operation.
A further object of this invention is to provide, in a textile inspection machine, a novel driving mechanism for moving a textile fabric across the inspection board of such machine, in either direction, at a controlled and constant speed and under a controlled and uniform tenslon.
Other objects of this invention, together with certain details of construction and combinations of parts, will be apparent from the following detailed description and claims.
According to this invention there is provided, in a textile inspection machine wherein a textile fabric is drawn from a supply roll, passed across an inspection board and wound onto a batching roll, a feed roll which engages the textile fabric and an adjustable drive for positively rotating said feed roll, in either direction, at a controlled and constant speed. There is also provided an adjustable drive including slip means, such as a hydraulic torque converter, for applying a torque to the supply roll tending to rotate the same in a direction opposite to that necessary to unwind the textile fabric therefrom so as to impose a controlled and uniform tension on the textile fabric as it leaves the supply roll. The batching roll is also provided with an adjustable drive including slip means, such as a torque converter, tending to rotate said batching roll at a peripheral speed greater than the peripheral speed of the feed roll so as to take up the textile fabric at the proper rate and to impose thereon a controlled and uniform tension. The slip means in the 2 supply roll drive and in'the batching roll drive not only make for smooth and uniform operation of the textile inspection machine, but also compensate automatically for changes in the diameter of said rolls as the textile fabric is drawn therefrom and wound thereon.
The textile inspection machine is also provided with reversing means to enable the textile fabric to be drawn from the batching roll and wound back onto the supply roll. The reversing means may take the form of an electrical switch for reversing the direction of rotation of the feed roll drive and for stopping the batching roll drive, whereby the slip means in the batching roll drive will permit the fabric to be pulled from the batching roll by the feed roll and will also impose the proper tension thereon. The supply roll drive will then wind the textile fabricbaclc onto the supplyroll.
A preferred embodiment of this invention is shown in the accompanying drawing, wherein Fig. 1 is a perspective view of the textile inspection machine, and
Fig. 2 is a wiring diagram of the textile inspection machine.
Referring now to the drawing, the reference numeral 9 designates a machine framework including uprights H1 at the upper ends of which is journalled for tilting motion an inspection board I l carrying idler rolls l2 and I3 at. the ends thereof. The inspection board H and the idler rolls l2 and I3 support for travel across said board, a textile fabric l4 coming from a supply roll 15 carried on a mandrel l6 journalled for rotation in the framework 9. Mounted for ,ro tation in the uprights ill of the framework 9 are a feed roll H, a measuring roll [8 and idler rolls l9 and 2|. A dancer roll 22, carried by arms 23 pivotally suspended from the inspection board II, is provided to compensate for any irregularities in the movement of the textile fabric I; from the feed roll I 5. The textile fabric I4 is adapted to be passed over the feed roll ll, around the measuring roll l8 and under the idler rolls l9 and 2|, under the dancer roll 22, over the idler roll l2, across the inspection board II, over I the idler roll I 3 and to be finally wound onto motor 25 drives the feed roll I! through a magnetic brake 26, which cuts in automatically when the motor 25 is stopped to prevent override, a
, V-belt drive 21 operatively connected to a gear reducer 28, a sheave 29 on the output side of the ear reducer 28 which in turn is connected to a sheave 30 attached to the feed roll I! by means of a V-belt 3|. 'Ihe sheave 30 is adjustable to 'permit the speed of the feed roll I! to be varied over a Wide range. To impose a tension on the textile fabric: l4 between the supply rolli5rand' the feed -roll ll, there is provided a reversible motor 32 operatively connected to the mandrel 18 through a hydraulic torque converter 33 and a The reversible motor 32 sup- V-belt drive 34. plies a torque to the supply roll l5 in a direction opposite to that necessary to unwind the textile fabric I4 therefrom. A'manually operated" reversing switch 35 is provided to control the-db rection of rotation of the motor also as to permit tension to be applied to textile fabric M being drawn from a supply roll l5 which is wound in either the face-in or face-.out position, i. e. with thesssurface of the textile fabric .to' "be inspected facingvtoWard'or; away from-the center of thesup-ply roll 15. The batching roll 2 i'is driven byrmeans of a :motor a variable ratio V-belt drivez3'l,lathydraulic-torque converter 38 and a eralaspeed of the-feed r011 H, which adjustment g is madeby me'ansof torquearod 4i, bevel gear 42, torque :rod 4-3and controllrnob A l."
