Description
March 25, 1952 A. VAN VEEN FEEDER FOR ENVELOPE STUFFING MACHINES Filed May 31, 1946 of different sizes.
Patented Mar. 25, 1952 FEEDER FOR ENVELOPE STUFFING- MACHINES iantmrvanveen, Cantonflen'ten Conn. AppiicationMay 31, 1946, SeriatNo. 673,409 12 Claims. (Cl, 211- 9) This invention relates to envelope stufiingmachines and more particularly to a mechanism for automatically picking sheets from hoppers and depositing them in such machines.
An object of this invention is to provide an improved sheetpicking mechanism for such ma,- chines.
A further object is to provide such a picking mechanism which will operate with a, minimum of movement for, the work accomplished and which will simultaneously pick a sheet from one hopper while it deposits a sheet from another hopper upon the machine.
Further objects and advantages of my invention will be more clearly, understood from the i whicharesuitablymounted a. series of vertical supporting members 6: A series of hoppers are mounted on. said vertical membersas illustrated insFigs. 2;.to:4, andsecured thereto by means of bars?! towhich are-attached the bottom platesB ofjthe hoppers. These hoppers are arranged'in pairs, each pair including one hopper at one. side ofthemachine and another hopper at .the.opposite; side, and are, inclined downwardly. towards the-center of the machine.
.Eachhopper has a. pair of side plates 9. which. may beadjustably positioned upon; the plate, 8 by suitable mechanism,- not shown, which is preferably located under said plate; the saidside plates! beingadjustable to accommodate sheets The fronts of. said; plates have suitable stops, not shown, toengage the marginalfside portions of the sheets and retain a stack of sheets in the hoppers whilepermitting. the front sheets to be withdraWn-fromthe stacks by, the picking mechanism.
The Q said. picking mechanism is preferably mounted atthe-top; of the machine andsupport: 1 edl centrallythereon"by brackets It. Upon the said brackets there are mounted supports; l3,- upon which are; hung, at opposite sides; of the as shown, and includes two sets brackets, suction pipes it that are connected,
through a flexible hose It, with each of a set of picker fingers I6-l6' that are secured to an oscillating shaft I! which is swivelly mounted in thebrackets I2;
A driving shaft I8 is rotatably mounted in said brackets and carries therewith a cam i9 which.
operates. a supporting frame 26 that is hung for vertical sliding movement upon the shafts l'il 8, as; clearly shown. in Fig. 1. This frame consists of-side bars 2| secured together at the top by an adjustable. plate 22 that carries a' roller 23 which engages the cam It; the said bars beingysecured together at the bottom by a bracket 24 upon which is hung a stripper and pusher plate 25. having downwardly turned ears 2626.
Each feeding mechanism is located between the two opposed hoppers in its respective pair, of spaced picker fingers l6l5, for each hopper at each side of the machine, and a stripper and pusher plate 25 which is disposed between said fingers. The
said fingers preferably consist of a tube 27 which is clamped to a bracket 28 that is secured to therocker shaft "and the picking portion of saidfingers is preferably. provided with a tubular sleeve'29 of resilient material, such as rubber or the like, and a row of perforations 36 extends through said tube and sleeve. At the upper end of each of said fingers there is attached a. flexible hose l5 which connects the finger.
with one of the pipes I 4. A spring 3! may; be anchored in a suitable manner, preferably to the rocker shaft 17, and connected to the frame 20 foriurging said frame in a downward direction to retain the roller 23 in engagement with the cam l9.
Belowthe picker fingers, there are provided a pairof feed shafts 32 that are rotatably mounted 1 insuitable bearings, not shown. The said shafts arerotated in opposite directions and carry thereon, for each picker mechanism, a pair of rollers 32 which are preferably resilient and rotated in a downwardly direction relatively to a vertical axis extending through the pusher plate 25.
Below said rollers, there is provided a conveyor, preferably in the form of a link chain .33, which extendsaround sprockets 34 on shafts 35, only one of said. sprockets and shafts being shownin 'the;,drawings.
the direction of the arrow 36 and has, at spaced The said linkchain is driven in intervals thereona series of pushers 37.
The shaft I1 is rocked by a lever 33. WhiChiS: is drivenby operated vby a. connector. bar. 39 that.
-66 ,a suitable. mechanism; notishown.
The operation of my above described sheet picking mechanism is as follows:
The sheets which are to be deposited upon the conveyor are first loaded into the pair of oppositely disposed hoppers and the machine is set in motion. The bar 39 will then oscillate the rocker shaft I! and therewith the picker fingers 16 so that one set of fingers will engage the sheets in the hopper at one side of the machine and the other set of fingers will engage the sheets in the hopper at the other side of the machine.
As a set of said picker fingers l6 moves into contact with the sheets in the lower ends of the hoppers, a valve mechanism, not shown, which connects the suction pipes [4 with an air suction system, is operated to cause a suction through that set of picker fingers so that it will draw the first sheet in the respective hopper against the fingers. The fingers are then swung away from the hopper by the shaft l1, while the opposite set of fingers is swung towards its respective hopper, and, as the said fingers move past the stripper plate 25, the sheet of material which was adhered to the said picker fingers is stripped therefrom and left upon the respective face of the stripper plate. The cam I9 will then cause movement of the frame 20 to lower said stripper plate downwardly and the pusher fingers 26-26 will push the sheet thereon between the spaced pair of rollers 32. These rollers will then engage the said sheet and feed it downwardly onto the conveyor whereby it is carried to another part of the machine.
It will be understood from the above description that by my invention I have provided a highly efiicient sheet picking mechanism which may be used on many different kinds of machines such as automatic envelope machines, collating machines, stuffing machines and the like. The said mechanism operating to simultaneously deliver a sheet from one hopper upon a desired portion of the machine while it is picking a sheet from another hopper. This eliminates the necessity of stopping the picker fingers in the delivery position while traveling from one hopper to the other, as in the case where a single picker finger is used, and thereby greatly increases the efliciency of the machine and eliminates highly objectionable vibration and Wear commonly caused by interruption of movement in mechanisms operating at high speeds.
