A primary object of the invention is to devise a novel feeder which will simultaneously feed material from a plurality 4of sources and which is self-synchronizing.
The invention contemplates a mechanism which feeds a plurality of items at the same time from different supply sources and which comprises pull-out devices for each source and these devices being arranged to initiate operation simultaneously so that the items arrive at the same time at the receiving station, and the next pullout operation being arranged to commence after termination of the operation of the device having the longest feed cycle.
Another object of the invention is to provide a novel dual feeder for materials of different lengths, the feeder comprising a tray divided into a plurality of sections stocking sheet material and the like of different lengths and delivering such material to feeding mechanisms comprising coaxially arranged sets of rollers disposed in alignment with respective sections, the sets of rollers of each section being controlled by separate one-way clutches and the mechanism driving one set of rollers serving to connect and disconnect the clutch of the other sets of rollers, the feed rollers being operative for a sutiicient length o f time to feed the items to continuously running pull-out roller means so that even through the cycle of feed of either of said of sets of rollers should be less than the time it takes for the item to pass through the feed rollers, that item once it is in the grasp of the pullout roller means is insured of being discharged.
These and other objects and advantages inherent in and encompassed bythe invention will become more apparent from the specifications and the drawings, wherein:
FIGURE 1 is a top plan View of a feeding mechanism incorporating my invention; Y
FIGURE 2 is a cross-sectional view taken substantially on line 2-2 of FIGURE 1; Y
FIGURE 3 is an enlarged longitudinal sectional view taken substantially on line 3-3 of FIGURE 1;
FIGURES 4 and 4a areV enlarged sectional views taken generally Online 4--4 of FIGURE 1;
FIGURE 5 is an enlarged cross-sectional view taken substantially on line 5-5 of FIGURE 1; and y FIGURE 6 isan enlarged cross-section taken essentially online 6-5 of FIGURE 5.
`Describing the invention in detail and khaving specific reference to the drawings, the feed mechanism generally designated 2 is.shown mounted on a support structure 3 and'comprises a frame 4 including a pair of upright side members 5, 6 forming the sides of a tray 7 which has an inclined bottom wall 8. The tray 7 has dependent flanges 10 on its bottom wall 8 which are pivotally connected as by `a rod 12 to the upper end of a support rod 13 which lits through a vertical opening 14 in a bracket 15, the bracket 15 being pivoted on a horizontal bar 16 extending between and also secured to the side members 5 and 6.
The rod 9 is secured in vertically adjustedv position by a set screw 13 to position the inclination of thebottom wall.3 about a lower pivot-structure 19 to walls 5 and 6 to properly position its discharge edge 20 to the retard assembly 2:1 and the feed roll assembly 22 which structure is described in my copending U.S. application entitled Feeding Mechanism filed Apr. 6, 1965, Ser. No. 446,023 and which description is by reference incorporated herein.
In the present structure the tray 7 is divided into two side by side feeder sections 23, 24 by dividers 25 disposed intermediate members 5 and 6 and presenting vertical sides. The upper ends of the dividers are formed with dependent lug structures 23 which pivot and permit adjustment of the dividers laterally between walls 5 and 6 on a horizontal bar 29 which is secured to the flanges 10.
The tray section terminates at its lower end in said discharge edge 20 from which the articles feed into a nip 31 between the feed roller assembly 22 and the retard assembly 21. The feed roller assembly 22 comprises a shaft 33 extending transversely of the tray above its lower edge, said shaft 33 extending through bearings 34, 35 in side frame members 36, 37 of the main frame 23.
The shaft 33 journals a clutch quill 38 which has a grooved collar 39 within which operates a fork 40 which extends upwardly through an opening 41 in a housing wall 42 of a housing 43 which is connected to the external side of frame members 37. The fork 40 is adjustably xedly connected to a shifter shaft 44 which slidable mounts on upward extensions 45, 46 of the housing wall 42. A biasing spring 47 is sleeved on shaft 44 and compressed between the fork 40 and the interior of extension 46 and biases the fork in a direction engaging the clutch. The outer end of the shaft 44 is bifurcated and pivotally supports on a pin 48 a cam 49 which engages the external side 50a of the lug 4'5. The cam is connected to a handle 50 which in FIG- URE 5 is shown in the disconnected position ofthe clutch 51 which comprises interengaging jaw elements 52, 53 on the quill 38 and the shaft 33.
The shaft 33 carries a pair of feed roller subassemblies 54, 55 which are aligned with` the feeder sections 23, 24 respectively (FIG. 1).
The roller assembly 54 comprises a sleeve 56 sleeved over shaft 33 and connected thereto a set screw 57 which mounts a collar 53 on the sleeve, the collar 58 forming an .abutment for one end of a brake spring 59 which is sleeved over shaft 33 and bears against the internal side 60 of side frame member 36 (FIG. l). Thus shaft 33 is prevented from rotating freely whenever the clutch mechanism 51 is shifted leftwardly (FIG. 5) to disengaged position whereupon the pawl 62, which is mounted on a radial flange 63 on one side of a pinion 64 which is journaled on the quill 38 and one-way drivingly connected thereto with a ratchet wheel 65 with. which pawl 62 cooperates under the influence of spring 62a, is caused to freely rotate about shaft 33 as the rack 66 moves in the driving direction shown by the arrow in FIGURE 3, the rack riding on the lower edge on a pivoted slide assembly 68 fastened to the side member 37. The rack is driven by a crank 70 which is a component of the receiving mechanism such as a press. In the engaged position of clutch 51, the rack drives the pinion 64 which drives the pawl 62 which in turn drives the rack 65 which drives the quill 38 and the quill drives through the jaw clutch elements 52, 53 the shaft 33 which in turn rotates the pair of rubber or elastomer rollers 72, 713 which-are connected to the sleeve 56 by set screws 74, 75 which are threaded to the metal core portions of the rollers 72, 73 and abut the sleeve 56. Thus rollers 72, 73 are adjustable 70 axially on the sleeve 56.
The roller assembly 55 is similar to 54 and comprises a pair of rubber or elastomer rollers 77, 78 (FIG. 1) in- 3 tegrally connected to metallic cores 79, 80 which are sleeved on a cylindrical tube 81, said tube 81 being rotatively mounted on shaft 33 and at one end abutting the adjacent end 82 of sleeve or tube 56 and at the other end being connected to a clutch 83a. The clutch 83a is connected as by a set screw 82b (FIG. 5.) to a cylindrical coupling element 83 which abutsas at 84 a companion coupling 85 which is connected as by set screw 86 t'o the shaft 33. Both couplings have central, cylindrical, codn'nensional areas 86, 87 upon which is loosely mounted a clutch spring 88 half of its coils 89 embracing surface 86 and the other half surface 87. The end of the clutch spring 88 upon surface 87 has a radially extending outturned end portion 90 which projects through a slot 91 1n an operating sleeve or element 92, the sleeve 92 being rotatably mounted on its end portions on cylindrical shoulders 94, 95 on the coupling elements 83, 85. The sprlng is so Wound that upon the sleeve 92 being free to rotate, the spring Winds up tightly engaging the coupling elements and driving the roller assembly 55. The sleeve 92 is provided with outwardly extending stop or abutment pins 96, 97 which alternately are adapted to enter into a slot 98 and abut against a stop 99 on one end of a clutch operator generally designated 100 (FIGS. 1, 4 and 441:).
The operator 100 comprises an arm 101 connected to a pivot block 102 which is pivoted on a rod 103 mounted from side wall 36, 37. The block 102 carries a yieldable cam 104 Which comprises a support 105 having a downwardly sloping ramp with a spring finger 106 connected thereto and extending upwardly over the ramp and enA gaged by a cam bar 107 of an actuator 108, the bar being part of the adtuator 108 which is a bracket of U-shape and having its outer leg 109 overlapping the rack and connected thereto adjustably by a slotted nut and bolt connection at 110 as best seen in FIG. 3 so that the actuator rray be adjusted lengthwise of the rack and vertically a so.
"lhus it will be noted at each time the roller assembly 54 1s driven the clutch 83a is engaged whereby the roller assembly 55 is also driven. It will be noted that clutch 51 may be disconnected and only assembly 55 may be driven. However, the primary purpose of the instant mechanism 1s to feed two items simultaneously and it will be apparent that in the present structure even though the complete cycles of operation may be different of the two roller sections 54, 55, the two sections will commence their operations at the same time since both clutches will engage simultaneously and if one section runs longer than the other, then the clutches are overrun. In other words, clutch 83a is disengaged and clutch 51 is engaged, the roller section 54 will overrun the section S5. The items feed into a pair of continuously running pullout rollers 112, 113 which are close to the pullout rollers, said rollers 112, which may be rubber being mounted on a free rolling upper shaft 114, the pairs of rollers 112, 113 being in alignment with sections 54, 55 to grasp sheets therefrom.
The lower roller structure 113 is connected to a driven shaft 115 journalled from walls 36, 37 and shaft 115 is driven by a chain and sprocket assembly 115a from a conveyor roller shaft 116 which is also journalled on walls 36 and 37, the shaft 116 being connected to a suitable power source by chain and sprocket 118 which is timed with the receiving mechanism, namely, the printing apparatus (not shown).
The conveyor shaft 116 mounts conveyor tapes 120 which run along guides 121 suitably mounted on the support and the tapes y120 carry the stock 122, 123 fed from the trays beneath the hold down lingers 124 mounted on bar 103.
In order to control or stop overrunning of the roller assembly 55, a brake 12S is provided including a split band 126 adjustable about shaft 81 and having a react-ion arm 127 mounted about and to rod 103.
