Claims.v

This invention relates to Winding machines,

`and moreparticularly to a machine adapted for `or more rolls of narrower widths, and these narrower rolls are then further slit into a plurality `of bobbins or rolls of relatively narrow widths to provide cigarette wrappers. practice to form the bobbins in this last slitting It is conventional operation in a Width corresponding substantially to the circumference of the cigarettes to be formed, so that the bobbins may be used on cigarette making machines.

A.In this last slitting operation, some of the bobbins obtained are apt to be defective because of imperfections in the paper, or due to uneven winding, or for other reasons. The slitting machine operator marks these bobbins, usually by small paper tabs or ilags which are inserted in the'bobbin between the convolutions of the pap-er at the defectiveportion, during the slitting op- Veration. When the slitting and winding of the bobbins has been completed, the bobbins are removed and the imperfect ones, marked as mentioned above, are separated for rewinding to re- I move the defective portions of the paper.

This rewinding operation involves considerable 4diiiiculty because of .the narrow width of the ,paper-in` bobbin form, and because of the thin tissue like character of the paper. The narrow L Width of the paper makes it difficult to rewind the bobbinv without overlapping vor uneven edges. And the thinness of the paper makes it susceptible to easy breakage during rewinding. These factors have heretofore seriously restricted the speed f at which the rewinding operation may be carried out.

`In accordance with the present invention I have developed va rewinding machine that operates `with a high degree of accuracy and uniformity so rthat the rewound bobbins are fully comparable 'with the perfect bobbins obtained on the slitter,

and are free of overlapping or uneven edges and wound tightly and uniformly. Furthermore, the

winding machine of the present invention is characterized by a markedly high paper rewinding speed on the order of 1000 to 1500 meters of paper i per minute, which is more than three times the speed of rewinding machines .heretofore in use.

This machine is arranged with a rewinding spindle so that operation may be carried on efficiently from an open side. Also, the machine is constructed with a low center of gravity and incorporates a unique arrangement for mounting and counterbalancing the rewinding spindle so that vibration at the high operating speeds is avoided.

An embodiment of the Winding machine of the present invention is illustrated in the accompanying drawing, in which:

Fig. 1 is a view in side elevation, vpartly cut away, of a complete machine embodying the invention;

Fig. 2 is a corresponding right end View;

Fig. 3 is an enlarged detail of the mounting for the bobbins to be rewound; Y

Fig. 4 is a corresponding sectional detail taken on the line 4-4 in Fig. 3;

Fig. 5 is adetail showing the arrangement of the spindle member for receiving the rewound bobbin; and,

Fig. 6 is a further detail of the guideway for the spindle member.

As illustrated in the drawing, the numeral I0 designates a frame structure which may be secured to a floor or other suitable supporting base as indicated at I I. The frame structure I0 comprises a table portion I2 adapted to support the various operating elements of the machine.

This table portion I2 has a right angular extension I3 at one end of which is mounted a bobbin supporting frame comprising a base portion Ill` which is slidablyarranged in anyconventional manner, such as by an undercut rib-and-groove arrangement (not shown), on the extension I3 so that ,it may be shifted tr'ansverselyas4 by an adjusting wheel I5.

The bobbin supporting frame also includes a pair of standards I6 extending upwardly to support a bobbin of paper to be rewound as at I'l. The standards I6 are bifurcated `by Vertical slots I8 at their extending ends to provide supporting journals for the bobbin I1 as described further below, the slots I8 preferably being inclined somewhat from thevertical (see Fig. 3) in accordance with the direction of withdrawal from bobbin I'I.

The bobbin I'I is mounted in the standards IE on a carrier I9 having an integral flange portion 20 and a threaded portion 2| `adapted t0 receive a threaded collar 22 for holding a complementary flange member 23 in place. According to usual practicerthe bobbns I'I are wound on a core 24,

`and this core 24 may be clamped between the integral vflange Vportion `2|)v and ,complementary flange 23, as shown in Fig. 4, .tosecure .the bobbins on carrier I9.

The carrier I9 is further formed with reduced end portions 25, each of which is fitted with a bearing member 26 spaced for disposition in the slots I8 of standards I6. Carrier I9 is located transversely in the slots I8 by a stationary positioning element 21 fastened on one standard I6 by screws 28 or the like, and a yieldable positioning element 29 assembled on the other standard I6. This assembly is eiTected by a dowel pin 30 pressed into positioning element 29 and loosely tting an aperture 3| in standard I6, and a retaining pin 32 having a shank 33 extending through the positioning element 29 and terminating in a threaded portion 34 engaging the standard I6. The shank 33 of retaining pin 32 carries a spring as indicated at 35 in Fig. 4 so that the positioning element 29 is yieldably biased toward the standard I6.

The upper edge of the positioning elements 21 and 29 are beveled as shown so that the carrier VI9 may be tted easily in the slots I8 between ,the positioning elements 21 and 29. And as the Vyieldable positioning element 29 is biased toward the standard I6, it will locate and maintain the carrier I9 against the stationary positioning element -21 which may be adjusted to the proper transverse alignment of bobbin I1 in the ma- .chine by means of the previously mentioned adjusting wheel I5.

Contact between the carrier I9 and the po- ,.sitioning elements l21 and 29 is made through hardened balls 36 pressed in the ends of carrier I9 and inserts 31 of ber or the like fitted in the faces of the positioning elements which reduces the wear so that it is negligible at this point. Adequate drag on the bobbin I1, so that it will unwind evenly during operation of the .machine, is provided by a brake arm 38 pivoted Paper is withdrawn from the bobbins I1 mounted in standards I6 by a Winder drum 46,

which is carried on a shaft 4I journaled on frame structure I6 (see Fig. 2) and driven from a motor 42 through a suitable belt drive. The paper withdrawn from bobbin I1 is led to the winding drum 40 in selective nights over guide elements mounted on frame structure I to prevent any sagging or slack in the paper. As illustrated in Fig. l, a series of stationary guide elements 43 are mounted on the table portion I2 of frame structure IIl, a second series of guide elements 44 'are arranged on a pivoted mounting for angular adjustment, and further guide elements 45 are located adjacent the winding drum 40. This arrangement allows the paper to be trained according to va variety of patterns through the vguide elements as illustrated by dotted lines in Fig. 1, so that an even and steady travel can be obtained with the particular paper being handled.

The paper delivered by the winding drum 40 is taken up on a spindle member 46 which is arranged similarly to carrier I9 with an integral flange portion 41 and a complementary flange 48 and retaining collar 49 to receive the rewound bobbin 50. This spindle member 46 is disposed to position the rewound bobbin 56 in peripheral contact with the `winding drum 40 and is mounted for displacement to accommodate the increase in 'size of the rewound bobbin 50 during the rewinding operation.

The disposition of spindle member 46 in this manner is provided through a mounting on a movable support column 5I. The spindle member 46 is carried in a bearing block 52 at the head of this column 5I which is free for vertical movement in aligned apertures in the table portion I2 of frame structure I0 and a bracket 53 extending below the table portion I2. The movable support column is formed in massive proportions and weight with respect to the spindle member 46 so that a low center of gravity is provided which stabilizes the spindle member 46 at high operating speeds and maintains the rewound bobbin 5I] in contact with the winding drum 40. This movable column 5I is counterbalanced by a weight 54 of similarly massive proportions suspended by a sprocket chain 55 trained over

sprocket wheels

56 and 51 from the column 5I. The `counterweight 54 is adjusted in relation to the column 5I so that the spindle member 46 may be easily displaced to accommodate the increase in size of the rewound bobbin 50 while maintaining efrective contact with the winding drum 40 during the rewinding operation. The sprocket wheel 56 is fitted with a lever 58 for raising the spindle member 46 from the winding drum 4D when desired, and a latch 59is disposed as shown in Fig. 1 to engage the bearing block 52 and retain the movable column 5I in raised position while the rewound bobbins 56 are removed.

To maintain the axis of spindle member 46 in alignment with the axis of shaft 4I carrying winding drum 40, an arm 66 is also mounted at the head of movable column 5I to extend to guide structure 6I. This guide structure 6I is supported on the table portion I2 of frame structure I0 and comprises two vertical guideways 62. The arm 66 extends between these guideways 62, and carries a bracket 63 adapted for mounting roller bearings in contact with the inside faces of the guideways 62 as at 64 and with both edges of the guideways 62 as at 65. By this arrangement the spindle member 46 is supported in aligned position at a point spaced from the movable column 5I so that an adequate leverage can be obtained to overcome the turning movement imposed on spindle 46 at the high speeds employed according to the present invention. As a result the spindle member 46 is maintained in accurate winding alignment so that the rewound bobbins 5I] are built evenly and true.
