Wheeler, Brooklyn, N. Y., assignor to International Cigar Machinery Company, a corporation of New Jersey Application September 25, 1936, Serial No. 102,445

36 Claims.-

This invention relates to cigar machines, and more particularly to wrapper transfer mechanism therefor for transferring wrappers from a source of supply, such as a wrapper or binder cutting die to cigar rolling devices.

The invention relates to the type of cigar machine disclosed in co-pending application Serial No. 162,455; filed September 25, 1936, by Sigurd Clausen, and constitutes improvements in the transfer mechanism thereof.

In the present invention there is provided a rotating main cam which drives a roller disk turning a vertical shaft to which a swinging hor izontal arm is attached,- and a stationary follower cam which guides the wrapper transfer arm pivoted to the said swinging arm and which swings the carrier head mounted on the said wrapper transfer arm. The aforesaid disk has a number of symmetrically located cam followers which engage at least in pairs with a number of open tracks of the main cam, the latter being so arranged that, while the cam itself performs a continuous rotary motion, the disk turns intermittently, dwelling at given points and rotating at different speeds in different positions. The follower cam has two closed tracks with the outer of which engages a follower carried by the wrapper transfer arm while with the inner track engages a roller carried by a crank attached to the shaft of the carrier head itself, the said crank embodying a gear segment which at one point of the wrapper carrier path engages with a curved racl: attached to the follower cam, thereby rotating the carrier head through a given angle while guiding it in its path.

carrier head is divided by a cross-wall into two chambers communicating by an opening said cross-wall fitted with a valve held open against a stop by a spring. This valve remains in the open position as long as a sulficient number of the suction holes in the first chamber are covered by the wrapper. But, as the wrapper is pulled off the suction head onto the cigar bunch, the air entering the chamber through the vacated holes pushes against the valve and closes the same, thereby increasing the suction effect in the second chamber.

At the end of the delivery portion of its path during which the wrapper is fed to the bunch, the suction head engages the outlet of a stationary pressure pipe which delivers, from a presra chamber supplied by a continuously running compressor, a puff of compressed air at given intervals controlled by a cam, this puff overcoming the remaining suction on the flag end of the wrapper thereby preventing the same from being torn.

The chief object of this invention isto provide means for transferring wrappers to a wrapping device by moving the carrier in a closed path to and from a wrapper supply position, and a wrapping position, and thereby improve the efficiency of the machine and increase its output.

A further object is to provide a single movable member which moves the transfer mechanism in a closed path, and eliminates the necessity of return movement of the carrier mechanism to the wrapping device over the same path as in the case of existing machines.

It is a further object to provide a single movable plate cam which acts as the driving medium for the transfer head, and which operates in conjunction With a stationary plate cam for controlling the wrapper applying movement of the wrapper carrier head as said head moves through a closed path to andfrom wrapping position.

It is a further object of the invention to provide relatively movable members which impart movement to a wrapper transfer head, and control the path of movement thereof to perform the functions incident to the proper delivery of Wrappers while the head is moving in a closed path.

The invention also contemplates the provision of mechanism for moving the wrapper transfer head continuously with a varying speed in a closed and irregularly curved path to and from wrapper applying position and wrapper receiving position, except for pauses at the receiving and the paste applying stations.

The invention also consists of the provision of mechanism connected to the suction system of the machine which allows said system to be cleaned of any obstructions which may happen to clog or otherwise render it ineffective.

The invention also contemplates the provision of a device for removing the flag end of a wrapper from the wrapper carrier as the carrier head reaches a position where said end is to be dis charged. This device becomes operative by relative movement of a cover mounted upon the carrier head, and a compressed air nozzle or directing means when the head is swung to final wrapper delivering position.

It is a further object of the invention to provide a suction system having a simplicity of construction heretofore unknown to the art, in which the wrapper carrier head is mounted upon articulated members having but a single path through which suction is conducted to said head, thereby providing a constant uniform quantity of suction thereto, and cutting down the suction loss due ordinarily to eddy currents set up in conduits having a plurality of paths.

It is an additional object of the invention to furnish a carrier head of novel construction in which the suction is diverted by changes in air Velocity and pressure from a portion thereof as the wrapper is applied to a bunch so that the remaining wrapper portion is more firmly held to the head during the latter part of the wrapping operation.

With these and other objects not specifically mentioned in view, the invention consists in certain novel features of construction, combination of parts, and arrangements of instrumentalities, which will be hereinafter more fully described and then set forth in the claims hereunto appended.

While the transfer mechanism shown is especially adapted for use in a cigar machine utilizing a duplex or multiplex cutting die turret, it also finds ready adaptability for use on a cigar machine using but a single cutting die.

Fig. 10 is a top view, partly broken away, showing the relative position of the improved wrapper carrier to other units of the cigar machine.

Referring to Figs. 1, 2 and 4, the improved wrapper transfer is mounted on a hollow column [0 fastened on the base-plate H of the machine and communicating through an opening in the latter with a casting [2 which is connected to a suction system and has a valve I 3 controlled by a cam-operated rod M. In a bearing I5 of column Ill and a bearing l6 attached to baseplate H is mounted a vertical shaft I! having a bevel gear 18 in mesh with a bevel gear I9 on a drive shaft 20 journaled in bearings 2! on side frames 22. The column 10 which has a horizontal arm 23 terminating in a bearing 24 in which is journaled a hollow shaft 25, may also be reduced as shown in Fig. 1 to allow the carrier head 36 to pass by unobstructedly. Bearing 24 may be apertured and have secured therein a plug 24' so that upon its removal a blast of air can be directed through the suction channels to remove any stoppage thereof or Waste materials that may be present.

To the top end of shaft I! is keyed a prime mover comprising a cam 26 provided upon its under surface with a system of open tracks 21 engaging with followers 28 on a horizontal disk 29 mounted on hollow shaft 25. The followers 28 are symmetrically placed on disk 29 and the tracks 21 of cam 26 are so arranged that the shaft is by the latter set into intermittent rotation at variable speed, the shaft 25 dwelling at certain points 30, Fig. 5, at which the tracks form concentric circles, while at other points it turns, slowly or fast according to the curvature of the tracks. There are at least two followers in engagement at any one time, a new follower entering a track of the cam before any one of the engaged followers emerges from its track. Thus in the position shown, which corresponds to the pick-up position of the carrier at the die, the follower 28' is in track 21' and the follower 28 in track 21". The rotation of cam 28, in the direction of the arrow, causes the follower 28 to engage the path 30 and follower 28" to track path 30", but before follower 28 leaves the track 21', the follower 28" which describes a path 30" will enter track 21", and so on, thus turning disk 29 and shaft 25 in the direction of the arrow.

To the lower end of shaft 25 is fixed a hollow arm 3! which on a bearing 32 pivotally supports a hollow arm 33 held on arm 3! by a bolt 34 turning on a bearing 34. It will be readily apparent that the connection furnished by bolt 34 affords I an extremely simple device for dismantling the carrier head supporting unit if that be desired for cleaning or any other reason. The free end of arm 33 forms the bearing for a holder 35 to which the wrapper carrying suction head 36 is attached. The arms 3| and 33 have been formed with but a single path for the suction, so that eddy currents will be kept down and a more uniform and constant pressure will always be maintained. The shaft 25 has ports 25 and 25" registering with ducts inarms 23 and 3|, respectively, and the holder 35 has ducts 35' registering with the opening of head 36, thus establishing a single and continuous suction path from the valve I3 to the wrapper W. At its ends, the bore of shaft 25 is closed by plugs 31 and 38. The holder 35 is keyed and bolted to a shaft 39 turning in a bearing 40 in arm 33 and carries an arm 4i provided with a hub resting on bearing 40 and a cam follower 44. The arm 33 has a lateral projection 42 carrying a cam follower 43. The followers 43 and 44 engage in tracks 45 and 46 in the under side of a stationary cam 47 attached to bearing 24, the followers 43 guiding the shaft 39 in a predetermined path 48, and the followers 44, at each portion of this path, swinging the suction head 36 to the proper angle for applying the wrapper to the particular cigar shape for which the machine is designed.

From the pick-up position 36, Fig. 4, the path 48 takes the wrapper carrier to position 36' at which paste is applied to the tuck end of the wrapper and the said tuck end is delivered to the cigar bunch B in the wrapping device by the tuck needle in the usual manner, the wrapper then being rolled around the bunch while the carrier travels to position 36 in which the flag fui from a position 36" beyond the blow-01f position 36" to the starting position 36, this gear engagement causes shaft 39 to perform a rotary motion which is required to bring the suction head back into'the initial position of its cycle for picking up the next wrapper.

The continuous closed motion produced by this arrangement has the advantage of bringing the carrier from the wrapper pick-up position 36 to the tuck delivery position 36' by way of the short route past column 10 instead of returning over the much longer route via positions 36" and 36", thus permitting a greater portion of the cycle to be utilized for the wrapping operation, for the reason that this motion allows the transfer means to transfer bunches to, and cigars from the wrapping device 11. At the same time the carrier is moving to the delivery position.

When but a single wrapper cutting die is used, the carrier 38 starts from position 36a, Fig. 9, and has to make a forward half-turn 36 so as to reach the paster position 36 with its tuck end at the cigar bunch B as in the case shown in Fig. 4. But when arrived in position 36 after delivering the wrapper, it requires only a small additional turn to return to the original pick-up position 36a. The gear segment 52 and the coacting rack 53 are therefore not required in this case and are omitted, the arm of roller 44 having a plain hub and the lower portion of track 46 having the shape 45' which causes the carrier head to turn about roller 44 while moved on path 48 by roller 43 in track 45, thus turning the carrier into position From position 36" to position 38", through positions 36 and 36", the

track 46 is the same as in Fig. l. The path 48 and the track are not affected-by reversing the die as long as the shaft39 remains in the same v position.

The cam 35 and roller disk 29 are protected by a cover 54 supported by a bracket 55 attached to column l9 and by brackets 56 resting on cam 41.

The carrier head 36 is divided by a partition 5?, Figs. 1 and 3, into a forward and a rear chamoer which communicate through an-opening having a valve 58 tensioned against a stop 59 by a spring 60. This spring is so adjusted that the valve 58 is held open as long as a wrapper W covers the suction holes SI of the forward chamber, but after the forward portion of the wrapper has been fed to the bunch the air streaming into the uncovered openings 6! closes the door 58 and thus permits all the suction to act through holes 62 on the wrapper portion held by the rear chamber. After this remaining portion of the Wrapper has nearly all been delivered to the bunch, the valve I3 is closed by the action of rod I4, the resulting cessation of the suction through the carrier arms permitting the valve 58 to reopen, ready for the next wrapper.

When all but the fiag end of the wrapper W has been taken off the carrier head, the swing cover 58 of the latter, which is held in closed position by a spring 63, is opened by its engagement with the stationary nozzle 49 of an air blast system incorporated with the machine. An air compressor 84, Figs. 6 to 8, supported on a bracket 85 and driven by gears 66 and 6'! from the drive shaft 28 of the machine delivers compressed air through pipes 98 into a storage chamber 69 supported by the base plate II. The chamber 69 has a valve it operated by a lever H connected by a rod i2 with a chamber I3 fulcrumed on a shaft 14 and having a roller 15 held in engagement with a cam 16 by a spring within the valve 10. To the discharge opening of the latter is connected the nozzle 49 which fits over the duct 5! in the flag end of the carrier 36. The cam I6 is so timed that the valve 10 is opened at the moment when the duct 5| arrives belowthe nozzle 49, the resulting puifblowing the wrapper end off the carrier thus preventing its possible tearing. As the carrier then moves on, the nozzle 49 clears the cover and the spring 60 returns the same into closing position.

In Fig. 10, the relation of the wrapper carrier to other units of the cigar machine is shown. The bunch B is delivered to the wrapping device I! from position B in the crimper 18 in which the ends of the bunch are shaped, by a transfer 19 turning on a shaft 89. When wrapped, the bunch B, now a cigar, is carried by a transfer 8| turning on a shaft 82 into position 13" on the cradle 83 of the reroller 84, a knurled drum oscillating on a shaft 85. In delivery position B' on the cradle 83, the finished cigar engages with a knurler 36 at its head end while its tuck end is trimmed to size by a trimmer 81. While the bunch B is being wrapped in the wrapping device 11, the wrapper W for the next following bunch is being cut on the die 88 by cutting rollers 89, which are mounted in a carriage for reciprocatory movement across die 88' when said die is held stationary in cutting position (Fig. 10). The wrapper carrier head 35 picks up the wrapper W and carries it along the path 48, the cam 26 and the transfers 19 and 8i being so timed that no interference between carrier 26 and said transfers takes place at any time during the entire cycle of movement of the carrier. 7
