16 Claims. (Cl. 13138) This invention relates to a method of and apparatus for feeding cigar bunches or defectively wrapped cigars, and more specifically for feeding such articles to the wrapper applying section of a cigar machine.

The invention provides an efllcient method of re-wrapping cigars originally rejected for wrapper defects. These rejected cigars are now either sold as seconds or manually re-fed into the wrapping mechanism of cigar machines for re-wrapping. This latter method is hazardous from the safety viewpoint. It is also slow and costly since an operator cannot manually supply a machine at full capacity. She will either miss some of its cycles. orstop .and start the machine for each cigar. Moreover, each machine requires a feed operator. With my'invention, rejects may be accumulated and then quick lyjand safely re-wrapped on several machines operating at full capacity and supplied by but one feed operator.

The invention consists in mechanically feeding cigar bunches to an existing cigar machine to utilize at full capacity the wrapper applying mechanisms thereof. The feed device may be transferred from one machine to another and is therefore readily adaptable to as many types of cigars as desired. I 7

It is an object of my invention to provide an apparatus for automatically feeding cigar bunches from a source of supply that may be readily and quickly attachedto and detached from existing cigar machines without' m'aterial alteration. I I It is a further object of my invention to utilize the existing movement of the cigar machine for motive power and to thereby coordinate the mechanical feeding of the cigar bunches with the normal cycle of the machine.

It is another object of my invention to provide a method and 'an apparatus for feeding group lots of. cigar bunches to the end that one feed operator may SuPPly' several machines at the same time.

It is still another object of my invention to provide feeding apparatus capable of handling the various shapes and sizes of cigars without employing costly model parts.

The apparatus can thus be moved from a cigar machine for one size and/or shape of cigarto another machine of different size and/or shape. In the accompanying drawings which form apart of this specification I have illustrated an embodinientbf my invention. f v Fig. 1 is a front elevation of the automatic cigar feeding mechanism; 1 v.

Patented Mar. 19, 1957 fer of a cigar from a cradle into a cigar transfer mechanism of the cigar machine; and

Fig. 8 is a plan view illustrating the automatic cigar feeding device in conjunction with an existing cigar machine.

With reference to Figs. 1, 2 and 3, the cigar feeding mechanism consists of a base 20 supported by

legs

22, 24 which are secured to the main body of a cigar machine of the type disclosed in the patent to Wheeler 2,316,828, granted April 20, 1943. Projecting from the top of the base 20 are a pair of

bearing brackets

28, 30 which support a vertical plate 32. This plate 32 forms the rear wall of a rectangular shaped hopper H wherein are stacked the cigar bunches C that are to be wrapped or re-wrapped as the case may be. a

The sides of this hopper H are formed by a pair 0 L-

shaped plates

34 and 36. The short legs of these side plates are adjustably secured to the rear plate 32. The front wall of the hopper H consists of a removable plate 38 slidably secured to the side Walls 'by means of the

brackets

45, 50 and the L-shaped

members

40, 42 respectively. The bottom of the hopper H is formed by

agitator plates

52, 54 pivotally attached by

hinges

56, 58 to the

side plates

34, 36 respectively.

0n the bottom side of agitator plate 52 (54) is-a bracket 82 (68) connected to a crank arm 78 (64) by a link (66). p The crank'arm 78 (64) is securedto a shaft 76 (62) supported in a suitable bearing of the bracket 28 (30).

The

cranks

70, 72 are secured to the

shafts

62, 76 respectively at their other end (Fig. 3) and the link 74 connects these cranks so that rotary movement of the shaft 62 will affect a similar movement of the shaft 76, causing the

bottom plates

52, 54 to move up and down; The movement of these bottom plates funnels cigars from the hopper into a'vertical guide chute 92 consisting of

side plates

84, 86 mounted on bars 88, 90 respectively and front end strip 104 (Fig. 1). ,The bars 8 8, 90 are 'adjustably held against plate 32 by screws passing through enlarged holes 94.

' The bottom cigar in the chute 92 rests on'the receiving trough-like'arm 103. Referring to Figs. 2 and 6,,the receiving 103 has integral ,legs .106, 108 pivotally supported on

pins

110, 112, which are mounted in integral bearing lugs of the base 20.

The arm 103 is operated by pin 114 extending into the leg 106 and engaging a slot 116 in a block 118, adjustably mounted on a piston rod 120. The rod 120' is supported in a suitable bore of the base 26. The com pression spring 124 bearing against the ,piston l22 moves the receiving arm to the position illustrated in Fig. 5. A pin 126,'whose movement will be later described,

.There is alsosecured to the shaft62 a crank arm 132 having 'on its. free end a roller 134. This roller is held in. engagement with the top of vertical slidingrack 136 by a tension'spring 133 anchored on its one, end to the rack and'its other end to the arm-132. The rackf136. is slidably supported by two

tracks

138, 140 mounted on, bearing bracket 30. The rack 136 drives a pinion gear 146 secured to one end of shaft 148 freely supported in suitable, bearings of bracket 30. A gear 150 mounted. on the other end of the shaft148 engages a horizontally:

sliding rack 152 mounted to' slide on the base 201m track 156 formed by bar 154 and the bracket 30. At" tached to the'mid-portion of the rack 152'is a bracket 158 adjustably supporting the pusher arm or fing'erl'160;

The entire movement of my new cigar feed .is'taken from an already existing reciprocating carriage 172 on a a track 174 and activated by a cam lever 173 to whichit is connected by the link 176. This carriage is normally. used to carry binder cutter rollers similar to those in Fig.- 1, the pin .166 engagestheforward end of the f of the arrow.
