DIRECTION-CHANGING MECHANISM FOR SHEET FEEDERS.
Application filed September 21, 1927. Serial No. 220,993.
The present invention relates particularly to means for changing the direction of paper sheets and the like, and theobject is to provide simple and edective means whereby the sheet whose directionof movement is to be changed, itself controls such change.
In the accompanying drawings:
Figure 1 is a plan view in outline of a dual-|L ruling machine, showing the novel mechanism applied thereto at the corner for starting the sheets that have been ruled by the first machine toward the second right angularly disposed machine.
Figure 2 is a perspective view-of the direction-changing mechanism,
Figure 3 is a detail sectional view of the controlling valve.
Figure 1 is a sectional view on the line 4-4; of Figure 3,
Figure 5 is a detail perspective view of the relief head,
Figure 6 is a bottom plan view of the same.
As stated above, the mechanism is shown in connection with a dual-L ruling machine. These apparatuses are well known, and it is believed to be unnecessary to describe them in detail.
The first machine is desi nated 7, and the second machine is identifie by the reference numeral 8. A -feeder for the first machine is indicated at 9. Between the two machines is the corner 10 that receives the sheets of paper which have been delivered to and ruled b the first machine 7. From this corner t e sheets are started at right angles from the direction of their delivery into the corner, on to a toboggan 11 and this toboggan delivers them to the second ruling machine 8.
The corner 10 is provided with endless tapes 12, on to which the sheets are delivcred, and these tapes carry the sheets to a position to be started on to the toboggan 11. This position is determined by a stop bar 13 that is, as is well known, adjustable to different positions along the tapes, depending on the size of the sheets that are being ruled.
In the present embodiment, a shaft 14, driven b sprocket gearing 15 from the sec ond mac ine, is provided with a suction roller 16. This suction roller may be of any desired type, but preferably is that disclosed in my Patent No. 1,494,303. This suction roller 16, it will be noted, has its axis of rotation disposed longitudinally of and preferably parallel to the tapes 12. Suction is created in the roller by means of an exhaust pump 17, having a conduit 18 leading to the said suction roller 16.
In this conduit is located a valve casing 19 mounted on a bracket 20 that is fixed to and therefore adjustable with the stop bar 13. The passageway through the valve cas- 111 1S controlled by a reciprocatory plunger va ve 21 having an annular groove 22 that is movable into and out of communication with the passageway to permit the passage oi air therethrough. This valve may also be provided with a suitable relief channel 23 atiording communication between the intake of the pump and atmosphere when the groove 22 is out of register with the passageways. Obviously therefore when the valve is in the position shown in Figure 3, suction is created in the roller 16 because of the communication afi'orded between the intake sid of the pump 17 and said roller.
The valve 21 is connected to a lever 24 fulcrumed at 25 on the stop bar 13 and this lever in turn has communication at 26 with a rod 27 of a piston 28. The piston 28 operates in a cylinder 29 mounted by brackets 30 on the stop bar 13. The cylinder 29 and piston 28 constitute a pneumatic motor of the suction type, and for operating it, preferably a second exhaust pump 31 is em,- ployed, to the intake side of which is connected a conduit 32 that is connected by means of a T-head 33 and a conduit 84 with one end of the cylinder 29. There is also attached to this T-head 33 a conduit 35 leading to a controlling head 36 adjustably mounted on the stop bar 13 by having a guideway 37, through which the stop bar 13 passes. Set screws 38 serve to normally hold the head against adjustment on the stop bar. The conduit 35 is in communication with a relief port 39 opening through a shoe 10 which overlies the path of the sheets, a portion of one of said sheets being illustrated at A in Figure 5. Preferably there are supplemental vent ports 41 in the head 36 opening into the port 39 and controlled by a rotary valve 42.
The two pumps 17 and 31 are operated by an suitable means. In the present embo iment a motor is indicated at 43,- and is geared as shown at 44 to the pumps.
The operation of the mechanism is substantially as follows: The sheets are delivered successively on to the tapes 12 and are moved thereby edgeways and longitumosphere through the conduit 35 and head.
36 so that the piston 28 is in its outermost position. When, however, a sheet has moved over the roller 16 and comes to a stop against the bar 13, as illustrated in Figure 5, it has closed the lower end of the relief port 39, thus cutting down the supply of air to the pump 31 and creating a partial vacuum which extends to the cylinder 29 through the conduit 34 (the character of this vacuum being controlled by the valve 42). As a result the piston 28 will move to its innermost position, or as shown in Figure 2, whereupon the valve will be moved outwardly, or to its open position as illustrated in Figure 3. The pump 17 is now in direct communica tion [with the suction roller 16 so that a artial vacuum is now being created therein and the indraft of air will cause the sheet that has effected these various operations to adhere to the roller 16, and be started to the second ruling machine. As soon as this sheet has been moved suificiently to uncover the port 39 of the relief head 36, the parts reassu me their original relation or in position to be operated when another sheet RITIVBS.
It will be noted therefore that in this apparatus the starting of the sheet at right angles is dependent on the arrival of the sheet itself.
From the foregoing, it is-thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art without further description and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the herein described invention.
