18 Claims.

This invention relates to automatic cigar transfer mechanism, its main object being to transfer a cigar from a cigar enveloping machine to a cigar banding mechanism, and at the same time turn the cigar 180 degrees about its transverse axis to reverse the cigar end for end so that it will be in the proper position to be banded when it arrives at band-applying position.

A further object is to provide a duplex cigar transfer having a novel construction and mode of operation and designed to carry the reversed cigar to band-applying position and move it away from said position after it is banded. For this purpose the duplex cigar transfer comprises a pair of reciprocable slides having movements of equal amplitude and at the same speed, and each provided with a set of clamping fingers which are moved into a position astride the reversed cigar and the cigar at band-applying position, respectively, to clamp the sides of the cigars. The first set of fingers delivers the reversed cigar to bandapplying position where it is gripped by the second set of fingers after being banded, and transferred to delivery position.

In the process of enveloping and banding cigars it is essential to keep them in the same right side up position as they were selected; accordingly, a further object is to prevent them from being turned circumferentially While taken from one position to another, especially when the banding mechanism is so located that the cigar must be swung about its transverse axis in order to apply the band to the right part of the cigar.

These objects in the present invention are achieved by employing a set of grippers which receive the cigar from the enveloping machine and swing it 180 degrees about its transverse axis. Thereupon the first set of clamping fingers of the duplex cigar transfer takes the cigar and delivers it to the banding mechanism, holding it until tl e bander head has descended onto the cigar and the folding fingers have engaged the band and folded the same partly around the cigar. [he folding fingers thus hold the cigar while the clamping fingers are released and moved back to take the next cigar from the grippers. The banded cigar is then gripped by the second set of clamping fingers and transferred to delivery position.

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:

Fig. l is a side view of the complete cigar transfer mechanism;

Fig. 2 is a plan View of Fig. 1 showing the grip- 5 pers for reversing the cigar end for end, and the duplex cigar transfer and its operating mechanism, which removes the cigar from the grippers and advances it to the banding machine;

Fig. 3 is a sectional end elevation of Fig. 1; and

Fig. 4 is a detail view showing the cigar being held by the bander fingers of the banding mechanism.

In carrying the invention into effect there is provided a device for gripping a cigar, mechanism for turning said device one-half turn to reverse the gripped cigar end for end, means for clamping the sides of the reversed cigar and removing it from said device and depositing it in band-applying position, and mechanism operating in synchronism with said means for clamping the sides of the cigar deposited at bandapplying position and transferring it away from said position. In the best constructions contemplated there is provided a duplex transfer 5 comprising a pair of reciprocable pivoted heads,

a set of clamping fingers on each of said heads to engage the cigar reversed by said device and the cigar at band-applying position, respectively, and transfer them to band-applying and delivery positions, respectively. These various means and parts may be widely varied in construction for the particular arrangement selected to illustrate the invention is but one of many possible concrete embodiments of the same. The invention, therefore, is not to be restricted to the specific construction shown and described.

The cigar transfer mechanism is operated from the main drive of a cigar enveloping machine such as disclosed in the patent to H. H. Wheeler, 1,899,174, issued February 23, 1933, by means of a chain l0 driving a sprocket ll actuating the cam shaft l2 (Figs. 1 and 2). The enveloped cigars C ejected. from the turret T of said enveloping machine are delivered to the transfer mechanism by means of swingable transfer arms l3 and 14 forming a part of the enveloping machine. Arms I3 are fixedly mounted on a shaft I5 journaled in bearings of the side frames of the enveloping machine (not shown) and provided with pockets on their free ends to receive the cigar as it is ejected from the turret T, as shown indotted lines in Fig. 1. Shaft 15 is suitably oscillated from the enveloping machine. The arms I4 are actuated by means of a plate cam l6 operating a connecting rod I! through a cam lever l8 having a follower engaging the cam track in one face of cam it, the upper end of rod l7! being connected to one arm of bell crank lever 69 and the other arm of lever l9 carrying a flanged stud which engages the hooked end 2| of a lever 22 connected to a lug 23 on one of the arms M. wardly they deliver the cigars C onto a table 24 10 and enter suitable slots provided in the table to receive them. The arms M are fixed on a sleeve 25'; loose on shaft l5 and having a circumferential slot receiving the screw whichsecures the hub of the arms 83 to the shaft [5, one of the arms I4 as heretofore described being equipped with a lever 22, thereby actuating both arms l4 in unison.

The bed l @4, of the enveloping machine carries 7 angle brackets I65, which support each of the side frames zli and 21 (Fig. 1).

the transfer unit is attached to projecting arms of the side frames H66 and IU'L of the enveloping machine (Fig. 3).

After the cigar C is delivered onto the table 25 24, which is supported by the side frames 26 and 2? of the transfer unit, arms [3 move down through the slots in the table 24 out of engagement with the cigar while arms !4 rest on the cigar and prevent the same from turning circumferentially. 'A hook-shaped pusher 28 then moves the cigar from beneath arms l4 and inserts it between the

grippers

29 and 36. Pusher 28 is fastened'to a rack 31 sliding in a track provided in the bracket 32 attached. to the table 24. The rack 3| is actuated by a gear segment 33 having a projecting arm 34 pivotally connected to one end of a rod 35, the other end of rod 35 7 being connected to a cam lever 36 provided with a follower engaging the cam track in the other face of cam I 6. The lever 36 is fulcrumed on the cam lever shaft 31 supported in bearings of the side frames 36 and 21. Gripper 39 is pivotally mounted on a pin 38 extending transverse-' ly'of gripper 3i! forming therewith a pocket in --which the cigar C is inserted by pusher 2B. Gripper 29 is held firmly against the cigar C in the pocket so formed by the action of a compression'spring 39 coiled about a stop pin connecting the grippers 2 5 and 36; The latter is provided with adjustable fianges forming the end wall of the pocket and is clamped to a sleeve 36a loosely mounted on the stationary vertical shaft 49, the grippers being oscillated about a vertical axis by means of a gear sector 4! fixed on sleeve 3% and meshing with a stationary rack 42 fastened to the table 24 (Fig. 2). Vertical shaft 48 is fixed in a slide 43 (Figs. 1 and 2), reciprocable in a slideway provided in the table 24. To the bottom of'slide 43 is fastened a block l connected by a link 45 to an arm 46 which is oscillated from a double arm cam lever 41 by means of a connecting rod 48, the lever 41 carry ing a roller 49 engaging a cam track of cam 50 mounted on cam shaft l2, and cam lever 4'! being fulcrumed on shaft 37 and the arm 46 being fulcrurned on shaft 5! supported by side frames 26 and During the forward motion of 'slide &3, imparted thereto from cam lever4'l, gear sector M is rotated one half-turn by the stationary rack 32, causing the

grippers

29 and 36 to turn therewith and thereby swing the cigar 180 degrees around its transverse axis without turning the cigar circumferentially. A coil spring 460, wound about the sleeve 38a on shaft 49, has one end anchored'in the gripper 36 and its other end is When the arms i3 are swung down- The table 24, of

held in a collar 40b fastened to shaft 46. The spring 40a causes the grippers 29 and 30 to turn with the'shaft 4i and eliminates any backlash between gear sector 4| and rack 42. The cigar in this manner is carried from its position shown 5 in Fig. 1 to a position shown in Fig. 2. In being swung the cigar is turned end for end so that it will be in the proper position to be banded when it arrives at the band-applying position.

The cigar C is then removed from the pocket 10 formed by grippers 29 and 30 by means of the first pair of clamping fingers 60 and 6| of the duplex cigar transfer, operated by mechanism which will be presently described, which take the cigar to the banding station and hold the same 15 admit the cigar advanced on table 24 by the 25 pusher the cigar having previously been deposited on table 24 by the transfer arms 13 and I l. The lever 53 is fulcrumed on a stud 52 supported in a bracket 55 attached to table 24, lever being actuated by a rod 56 connected to a cam 30 lever 51 fulcrumed on shaft 31, said cam lever being provided with a roller 58 fitting a cam track of cam 59. e

As soon as the cigar C has been removed from the pocket formed by grippers 26 and 30, the 35 latter return to their original position and stand ready to receive another cigar. The clamping fingers 66 and 6! are attached to arms 62 pivoted to a supporting head 63, each arm 62 being equipped with a roller 64 held by means of a 4g tension spring 65 against a wedge-shaped member 66 (Figs. 2 and 3), member 66 controlling the opening and closing of the pocket formed by fingers 66 and iii. Thewedge 66 is fastened to a slide rod 61, a portion of which has rack teeth 45 meshing with a gear segment 68 of arm 69, Fig. 3,

arm 69 being equipped with a roller 10 engaging the bottom of a cans rail H. The latter is supported from its ends by brackets 12 and 13 (Fig. 2) fixed on shaft 74 which is journaled in 50 bearings 15 carried by the table 24. An arm 76 projecting from bracket 13 is connected by a rod ll (Fig. 2), to one arm 18 of a double arm cam lever l9 actuated by means of a roller 86 on its other arm from a plate cam 8!. The action of 55 cam 8! through rod 17 operates the rail 1|, the descent of rail ll engaging the roller 16 of arm '69 which is pivoted on shaft 14 and causing the segment 88 to move slide rod (il outwardly, thus opening the fingers 66 and 6 l; the outward move- 60 ment of rod El compressingthe spring 82 thereon. When the rail H ascends, the spring 82 expands and returns the wedge 65 to its original position, thus closing the fingers 66 and BI.

'While the arms 62 are spread apart during the 65 V other ends pivoted on shaft 174' and the head 63 75 a it is slidably mounted on

shafts

14 and 81, whereby downward movement of the rod 86 will swing the head 93 downwardly on shaft 14 to bring the separated fingers 69 and BI into a position astride the cigar. When the fingers B and 6| reach this position they are closed on the cigar so that they will remove the same from the

grippers

29 and 39 during the transverse movement of head 63 on shafts l4 and Bl. To assure the removal of the cigar the finger 60 is of sufficient length to engage the mid-section of the cigar, the finger 69 having a notch in its bottom fitting the underlying arm of the gripper 29 to permit the finger 9t to straddle the same in order that the full length of the finger may engage the cigar. The transverse movement of the head 63 is controlled by means of a horizontal slide 89 which is guided in slide blocks 99 suspended from the table 29. Slide 89 receives reciprocating motion through a gear segment 9| of arm 92, segment 9i meshing with the rack teeth provided on the slide 89. Slide 89 is actuated by cam 8| having a cam groove receiving roller 93 on one arm of the double cam lever 94, the arm 95 of lever 99 carrying a rod 99 connected to the arm 92.

The slide 89 is provided with slotted blocks 91 engaging rollers 93 carried by the arms 99 of the heads 53 and see; in this manner a back and forth motion is transmitted to the heads 63 and 199. Since the construction of the head I00 on which the second pair of clamping fingers IGI and I92 of the duplex cigar transfer is carried, is similar to the head 63, like characters of reference are used to designate corresponding parts, and the description thereof need not be repeated herein.

The operation of the novel transfer is as follows:

The enveloped cigar ejected from the turret T is deposited on the table 24 by the transfer arms 93 and l 4 and then inserted between the

grippers

29 and 39 by the pusher 28. After the cigar has been swung 180 degrees by the

grippers

29 and 99, clamping fingers 6i and 6| descend and clamp the cigar and slide it sidewise to the band-applying position under the banding mechanism M of conventional construction, (Fig. 2), where the cigar is held between the fingers 69, 9| until the bander head H descends and presses the band against the cigar, whereupon the band folding fingers F swing inward, folding the band partly around the cigar as shown in Fig. 4. While the cigar is thus held by fingers F the clamping fingers 60, 6| are released when the rail it moves downwardly into engagement with the rollers 70. The clamping fingers 69, G! then rise and move back to their starting position, the bottom folding fingers K in the meantime having moved in and completely folded the band B around the cigar. The fingers 60, El and I95, 12 then descend, the former pair engaging the cigar now held by the

grippers

29, 39 and the latter pair engage the banded cigar previously delivered to the banding mechanism. The heads 63 and IE9 then move forward, the fingers 69 and iii of the former sliding the cigar to the bander and the fingers NH and I02 of the latter sliding the banded cigar from the bander to delivery position in which a pusher 93 on head Hit propels the banded cigar previously deposited by the clamping fingers of head I09 onto the delivery end of table 24. It will be observed that during the entire operation of the novel cigar transfer mechanism, the cigar is held firmly and in the right side up position so that the banded cigars can be repacked in the same box from which they were taken.
