6 Claims.

This invention relates to binder cutting and transfer mechanisms for cigar machines, its main object being to combine improved binder cutting and transfer means with a duplex binder die turret and the present application constitutes a continuation in part of my co-pending application Serial Number 183,405, led January 5, 1958.

The construction of the binder cutting rolls shown herein corresponds with that shown in said application, and a further object is to provide an improved mounting for the binder cutting rolls whereby they may be supported in suitable oppositely inclined positions to simultaneously coact with opposite edges of the die for severance of a binder thereon and the inclination of said rolls may be adjusted.

The binder transfer construction is similar to that shown therein, to have its head move in a horizontal plane in transferring a cut binder from the cutting die to the rolling apron, and is associated with a duplex die turret which makes a half turn after each die has ben severed and dwells while the cutter rolls sweep across the die. When a binder is to be transferred from one of the dies, the transfer head is positioned above the cutting station of the dies, the binder is raised into contact with the transfer head and held by suction thereon as the head oscillates in a horizontal plane to a position a small distance above the rolling apron. When located in proper position over the apron, the transfer head descends and the suction is cut off, thereby depositing the binder on the apron. Thereupon the transfer head is again raised sufficiently to clear the apron and swung back to receiving position. Still another object of the invention is to provide for adjustment of the binder transfer to permit the binder to be deposited in the proper position on the bunch rolling apron.

A further object is to increase which binders may be binder die turret to the bunch rolling table, thereby permitting the attainment of the maximum speed of binder cutting with the die turret and the operation of the bunch rolling table at the maximum speed. It binder transfers heretofore transfer head thereof has a parallel motion in an arcuate path extending over 180 degrees from the die to the table, whereas the movement of the present binder transfer has only approximately a 45 degree arc. Thus the interval allotted for the transferring of the binder is greatly reduced and the operation of the machine speeded up. Moreover the binder die may be the speed at placed close to the rolling table and the necessary floor space and the size of the machine is reduced.

It will be understood that the invention is not limited to the mounting of binder cutting rolls selected to illustrate the invention, but is applicable to the mounting of wrapper cutting rolls as well. In a broader sense, one of the objects of the invention is to provide an improved mount vfor cigar machine cutting rolls whereby they may be supported on a shaft passing through the rolls and whereon they may be adjusted into vartransferred from the z Will be noted that with f' in use'the binder ious inclinations relative to the cutting edge of the die.

With these and other objects not specifically mentioned in View, the invention consists in certain constructions and combinations hereinafter fully described and then specifically set forth in the claims hereunto appended.

In the accompanying drawings, which form a part of this specification and in which like characters of reference indicate the same or like parts: v

and y Fig. 5 is a Fig. 4.

Referring to Figs. 1 and 1b, the binder leaf is served by an operator to one of the dies |05 or lllEa of an intermittently revolving duplex die turret I I, such as disclosed in my co-pending application, Serial Number 183,405, filed January 5, 1938. After having made one-half revolution, the turret dwells and the binder B is cut from detail end elevation on line 6 3 of the served leaf by the rectilinear movement of the rollers I2, I3 across either the die |35 or die IU5a, whichever die is at the binder cutting station. Upon the return of the cutting rollers into initial position, the die head |56 of die |55 or the die head IOBa of die I'o'a (Fig. 4) ascends with the binder B into contact with the bottom face of the suction head I4 of the binder transfer I5, which at that time is in receiving position above the die. At the moment of contact, the suction in the die head is cut off and suction in the transto varying conditions of operation. The binder cutting mechanism just described is included in the subject matter of my continuation in part application S. N. 419,130, filed Nov. 14, 1941.

The binder transfer (Figs. 1 and 4), which forms the subject matter of my divisional application, S. N. 419,129, filed Nov. 14, 1941, is mounted on a hollow column 56 adjustably secured to the bed 24 by screws 51 passing through elongated slots 58 in the latter and fastening to the underside of the bed a bracket 59 having an fer is turned on, thus transferring the binder l from the die to the transfer head and holding it thereon while the same is moved along the path I6 to its delivery position above the apron Il of the rolling table I8. The head is turned during this movement to assume the desired oblique position on rolling apron, as indicated by the path I9 of the wrist pin I8 connecting the transfer head to the connecting rod 80 of bracket 83'.

The binder cutting rolls I2, i3 are supported from a stud (Figs. 1, 2 and 3) carried by a bracket 2l attached to a slide 22. The slide 22 is supported within a hollow rail 23 extending underneath the die turret head It and fastened to the bed 24 of the cigar machine by screws 25. The ends of the rail 23 are closed by cap pieces 25 and the slide 22 is provided with a recess 21 communicating with an oil groove 23 for lubrication of the bearing surfaces 29. The slide 22 has lugs in which is pivoted a link 3l connected to an arm 32 fulcrumcd on a shaft 33 in the base of the machine. The arm 32 is connected by a link 34 with a bell crank 35 fulcrurned on a shaft 36 and having a roller 37 in engagement with the track 38 of a cam 39 mounted on the cam shaft 4B of the machine.

As the cam 39 revolves in the direction of the arrow, the roller 31 moves in the path 4i to the position 3l', causing the bell crank 35 to assume the dotted position thereby through link 34 turning the arm 32 along a path 42 and thus moving slide 22 with bracket ZI and rolls I2, I3 across the die turret II.

The ball bearings 43 of cutting rollers I2, I3 (Fig. 1) are mounted on shafts 44, 45, which have a reduced portion on which the ball bearings are mounted, the axis of the reduced portion being eccentric to and inclined to the axis of the larger clamping portion (Fig. la), so that the rollers can be accurately adjusted to the desired inclination with respect to the cutting edge of the die. The ends of each of these shafts are concentric With one another, so that by turning them in their supports the inclination of the cutting rolls relative to the cutting edge of the die may be varied. The shaft 44 is clamped at each end in a bracket 45, having bearings 47 mounted on stud 29 and connected by a bridge arm 43, thereby providing a box formation which imparts rigidity to the same; and the shaft 45 is similarly supported by a bracket 49 having bearings 5i) mounted on stud 29 and connected by an arm 5I. Between the bearings of each of the brackets 46 and 49 there are adjustably fastened on stud 25 collars 52 having hollow ends enclosing torsion springs 53 anchored at one end to the collar 52 and at the other to the adjoining bearing of the respective bracket. Between the collar 52 and the non-tensioned bearing 5i) of bracket 49, there is fastened to stud 29 an arm 54 carrying stop screws 55 bearing on the bridge arms 48 and 5I. By turning the said screws 55, the collars 52 and thus the height of the rollers I2, I3 and their tension against the die can be precisely adjusted upwardly extending hub portion 60 projecting through an oval slot 6I in the bed into the base of the column 55. Projecting from and free to turn in a bushing 52 in the upper end of column 56 is a verticai tube 53 which extends down through the hub 5D into a bushing 64 in a downwardiy projecting yoke 65 of bracket 59. Into the lower end of bushing 64 is fitted a tube 66 held in place by a clamp 51 and connected to a suction chamber 65 in the bed of the machine, the tube 66 being provided with joints permitting expansion thereof as the column 5G is adjusted to a greater distance from the binder die.

To the top end of tube S3 is clamped a hollow transfer arm I5, which at its Vfree end carries a socket 69 to which the suction head i4 is clamped, the socket 69 being free to turn on and secured on arm I5 by a bolt 10 having its head mounted in the ball bearing 'II andthreaded into an internal lug of the socket 59 to hold the same against the ball bearing 'I2 of the arm I5. A screen 13 inserted into the lower end of socket 59 prevents leaf particles from being sucked into the transfer arm. The perforated suction plate 74 of suction head I4 is made readily detachable for cleaning by providing it with slotted lugs engageable with the depressible cone head of a spring-pressed bolt 'I5 at one end and with a fixed flat head of a bolt 'f6 at the other.

The socket E9 has a crank extension l? carrying a crank pin i8 engaging with a socket 'i5 at one end of a connecting rod 3i), the other end of which has a socket 8| pivoted to a pin 82 fastened in a bracket 83 clamped to bushing 62 in column 56. The connecting rod 853 is so adjusted that the suction head I4 is turned to the desired angle as the arm I5 carries it into position above the rolling apron II.

A sleeve 84 resting on the lower hub portion 55 of yoke 59 is loosely mounted on tube 63, this sleeve having an arm 35 carrying a ball-headedpin 86 adjustable in a slot at its free end (Figs. 5 and 6). A boss 87 of arm 35 supports a post 88 on which is anchored a spring 85 attached to a post 99 in a vboss 9| of a sleeve 52 clamped to tube 63, the sleeve 92 having an arm 93 carrying at its free end an adjustable stop screw 94 arranged to encounter a stop plate 95 attached to bracket 59. The clamp sleeve 92 carries a roller S5 resting on a cam piece 5'! extending upwardly from the loose sleeve 34. This cam piece is shaped to permit movement of the roller 95 from an upper to a lower position, or vice versa, as relative swing-ing motion between the sleeves 84 and 92 takes place. The cam piece 91 has upward Yprojections at the ends, providing positive stops for the roller 96 on reaching either level, t-hus preventing undue stress on spring 89 by moving the operating parts when the machine is not in operation.

On the ball-headed pin is pivoted the socket 93 of a connecting rod 39, the other end of which has a ball-and-socket joint IBI) pivoted to a cam lever I SI fulcrumed on shaft 33 and having a roller |32 in engagement with a track |03 of a cam |04 on cam shaft 40. As the roller |02 is displaced by cam m4 from position |02 to position |02, the arm 85 of the loose sleeve 84 is moved from position 85 to 85, carrying with it, by means of spring 89, the clamp sleeve 92, thus turning the tube 53 and with it the transfer arm l into delivery position above the rolling apron. In position 85 of arm t5, the stop screw 94, having moved from position 94 to 94", engages with stop plate 95, thus arresting the clamp sleeve 92 so that the further displacement of cam roller |62 from position |2 to ||!2 causes the loose sleeve to move alone from position 35 to 85" against the pressure of spring 89, thereby turning the cam piece 91 and causing the roller 96 to descend to its lower level. The tube 63 having been held in its upper or turning position by the resting of roller 96 on the high point of cam piece Sl, the transfer arm l5 will therefore drop, bringing the suction head I4 into contact with rolling apron Il. By now cutting olf the suction in head Id and turning on suction in rolling table i3 through mechanism of well known construction, the binder is transferred from the former to the latter. The transfer arm I5 then returns to its starting position for the next binder, being in transit raised to its upper position by the return motion of cam piece 91 due to spring 39 as the cam IEM brings roller H32 back into position itt on the return stroke of cam lever lill.

The relative vertical positions of the binder transfer and the rolling table and binder die are shown in Fig. 4. In the receiving position the cut binder is raised by the die head |08 above the cutting edge of the die to the suction plate 14, and in the delivery position it is lowered onto the rolling apron l1.

The various adjustments described above are necessary to compensate for the varying distances of the vertical axis of the neck of differ-- ent suction heads from the table 63 due to the different locations of the neck in various suction heads. It is necessary to maintain the suction head in a predetermined relation to the binder dies |05 and ||l5a which are supported in a predetermined position with their striking points lill, |98 and lilla, IIJSa respectively in predetermined relation to the path of the cutting rollers. Hence the screws 51 are unfastened and the column 56 is adjusted to move the suction head into the proper position above the binder die, and the throw or angular displacement of the suction head is regulated to cause it to assume the desired position above the rolling table.

With the particular type of cutter roll shaft employed it will be noted that the use of selfaligning ball bearings for permitting adjustment of its inclination is unnecessary and ordinary radial ball bearings may be employed. Moreover the provision of such a shaft having concentric ends fastened in the arms of the cutter roll frame assures rigidity thereof.
