7 Claims.

This invention relates to cigar machines and more particularly to improvements in wrapper transfer mechanism for use on cigar machines.

It is an object of this invention to provide novel wrapper transfer mechanism which is simpl in construction, easily adjustable and of a type especially adapted for use in conjunction with cigar wrapping mechanism in which the cigar wrapper carrier head is adapted to travel along a continuous and closed path during the operation of the machine.

It is a further object of my invention to provide an improved nozzle mechanism cooperating with the wrapper carrier head for blowing off the flag portion of the wrapper leaf from the wrapper carrier at the conclusion of the wrapping operation.

In automatic machines, it may be necessary to run a machine backwards in order to make suitable adjustments and for that purpose my invention also consists in the provision of an improved nozzle mechanism so constructed and arranged that the machine can be run backwards and the wrapper carrier head moved relative to the nozzle without breaking any parts of the machine.

It is an additional object of my invention to provide improved nozzle mechanism of the type in which the nozzle is mounted for movement independent of the Wrapper carrier head in order to allow it to be moved out of the path of the head whenever the machine is turned over backwards in order to prevent breakage of the parts of the nozzle and its associated operative parts.

The invention is also characterized by the provision of means forming a part of the nozzle which allows it to be adjusted readily in order to adapt it for use in producing cigars of all shapes and lengths.

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

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

Figure 4 is a plan view of the blow-off device; and

Figure 5 is a detail view, partly in section, showing the yieldable mounting of the nozzle.

Referring to Figures 1 and 2, the improved wrapper transfer mechanism is mounted on a hollow column (not shown) which may be of the same general type as that shown in co-pending application Serial No. 208,972, filed May 20, 1938 by H. H. Wheeler for Wrapper carrier operating mechanism, now United States Patent No. 2,235,857, attached to the base plate of a cigar rolling machine (not shown), and connected to its suction system in the customary manner. The column has a horizontal arm Ill terminating in a bearing ll in which is J'ournaled a hollow shaft I2 closed at its ends by removable plugs I3 and [4.

A gear [5 fixed on the hollow shaft I2 is driven in the same manner as disclosed in said patent above referred to, and therefore, in the interest of brevity, a more detailed showing and description of the same is omitted. To the lower end of shaft I2 is clamped a hollow arm It which is provided with a bearing l1 pivotally supporting a hollow arm [8 joined to arm it by a bolt 19. The free end of arm l8 forms a bearing for a holder 20 secured to a vertical shaft 2| turning in the bearing and carrying a suction wrapper carrier head 22. From the free end of arm [8 projects a lateral extension 23 which mounts cam follower 24. To the upper end of shaft 2!, which extends from the free end of arm 18, is fastened a cam piece 25 carrying a roller 26. The followers 24 and 26 engage in cam tracks provided in the under side of a stationary cam 21 attached to bearing l I, the follower 24 guiding the shaft 2| in a predetermined path and the follower 26 in each position on this path swinging the carrier head 22 to the proper angle for applying the wrapper W to the particular cigar shape for which the cam 21 is designed. The carrier head 22 is adapted to travel through a closed path each cycle of the machine from wrapper receiving to wrapper applying station and back to receiving position, all as disclosed in the above referred to Wheeler patent.

At proper points, the cam 27 has projecting studs carrying followers 28 and 29 adapted to be engaged by the cam piece 25 in the manner described in the above mentioned patent and thereby turning the shaft 2| and reversing the carrier head 22 after the same has delivered the wrapper and is returning to its receiving or pickup position. In the pick-up position shown in Figure 1, the carrier head 22 rests over the lifter head L of the die, the wrapper W being transferred from the latter to the former in a manner known in the art by a shift of the suction at the moment of contact.

The carrier head 22 is divided by a partition 30 into a forward and a rear chamber which communicate through an opening in the partition 39 having a weighted trap door 3| swinging on a shaft 32. Shaft 32 projects externally from the carrier head, and on an arm 33 clamped thereto has a cam follower 34, or other suitable valve operating device. The under side of carrier arm 35, by means of a bracket 35, carries a wedge shaped cam piece 3! projecting into the path of follower 34. The weight of trap door 3| is so chosen that the suction in the carrier is not suf-- ficient to lift the same from a stop pin 38 but strong enough to hold it against the partition33 after being raised into closing position. Thus the trap door 3| in this case is normally open thereby allowing the suction to act over the entire face of the carrier head 22. At a definite point in the path of travel of carrier head 22, when it is desired to shift the suction from the forward holes 39 to the rear holes 49 so as to augment that on the latter, the door 3| is raised by engagement of follower 34 with cam piece 31 and then is held closed by the suction until the same is cut off from the carrier head 22 upon ,delivery of the wrapper W.

When all but the flag end of the wrapper W has been taken off the carrier head 22, as it is being wound around the cigar bunch at the wrapping station (not shown), a cover 4| movably mounted on the head 22 and normally'held in closed position by a spring 42, is opened by engagement with anozzle 43 of an air blast system forming an active part of the machine. The nozzle 43 (Figure preferably is made in two parts in order to provide means for readily adjusting it to cooperate with all different shapes and lengths of wrapper carriers. This may be accomplished by securing one end of a sleeve 58 in the butt end of the nozzle and having it, pro lect and support the adjustable outlet portion of nozzle 43. With the outlet Portion of the nozzle correctly placed in respect to the duct 49 of carrier 22, it is retained in place by tightening a set screw 59. Any suitable air compressor may be used to deliver compressed air through pipes-44 (Figure 3) into a storage chamber 45 securedto the base plate of the machine. The chamber .45 has a valve 46 operated by a leve 41 connected by a rod 48 to a cam (not shown). To the-discharge opening of valve 46 is connected the nozzle 43 which fits over a duct 49 in the flag end of carrier head 22. The cam is so timed that the valve 46 is opened at the moment the duct 49 arrives below the nozzle 43, the resulting puff of air blowing the wrapper end off the carrier, thereby preventing any possible sticking, and permitting perfect application of the flag portion about the head of the cigar. As the carrier then moves on in its closed and unidirectional path, nozzle 43 clears the cover 4| and the spring 42 returns the same to its closed position.

The nozzle 43 is yieldably mounted so that as the machine is turned in a reverse direction manually, for adjusting purposes, or any other reason, the nozzle will be moved by the carrier head 22 out of its path of travel without breakage of any parts of the machine. According to the embodiment chosen for illustration, the nozzle 43 is provided with a hub .50 which is turnably mounted in an aperture 5! at the upper end of a bracket 52 adjustably fastened to chamber 45. Since bracket 52 is adjustable, it provides means for vertically setting the nozzle in proper position to suit the level of the flag end of the carrier head 22. An extending lug 53 of the nozzle 43 carries an adjustable stop screw 54 which normally abuts a stud 55 in bracket 52, and a spring 56 stretched between stud 55 and a stud 51 tends .to hold screw 54 against its stop. With the nozzle positioned as shown in Figure 4, it is set to register with the duct 49 at the proper time to blow off the flag portion of the wrapper.

When the machine is turned in a reverse direction manually, for reasons heretofore mentioned, the cover 4|, which is then in a closed position, will bear against the end of nozzle 43 and .rnove it as indicated by dot and dash lines, out of the path of the carrier head, thus avoiding breakage of any parts of the machine.
