z claims.
This invention relates to piler end stops, and more particularly to those devices which are used in combination with sheet feeding mechanism to enable the accurately aligned piling of the sheets fed thereby.
One of the objects of the present invention is to provide a piler end stop for use in combination with sheet feeding means which is labor saving in that it does not require any manual labor to operate the same.
Another object is the provision of a device of the class described which will operate in a rapid and eiiicient mlanner.
Still another object. of the invention is the provision of a piler end stop for use in combination with sheet feeding means which eliminates danger to the operator.
Still another object is to provide a device of the class described which is cheap and easy to install, operate and maintain.
Other objects and advantages will become apparent as the description proceeds and reference is had `to the accompanying drawing, in which:
Figure 1 is a side elevation of the apparatus of the present invention; and,
Y Figure 2 is a sectional view on the line II-II of Figure 1.
Referring mlore particularly to the drawing, the numeral I designates a machine which is constructed and arranged to feed sheets therefrom, for example, such as a machine for oiling metallic sheets. According to the prior art, sheets are fed from such machines up against the piler end stop and are subsequently removed when in'piled condition by a suitable conveyer.
According to the teaching of the present invention, a. support 2 is disposed adjacent to and longitudinally aligned with the delivery end of the sheet feeding mechanism generally indicated at I. In the present instance, the support 2 comprises a single or monorail which is shown as.
being H-shaped in section with the ilanges thereof extending horizontally. A carriage 3 is mpunted for longitudinal movement on the support 2 and comprises an inverted U-shaped member having wheels 5 which are adapted to run on the upper surface of the lower flange of the H-shaped support 2. Thus, the carriage 3 is adapted for easy movement longitudinally of the support 2.
When in the desired position, the carriage 3 is locked by means of a screw threaded shaft 6, which extends through one of the sides of the inverted U-shaped carriage 3 and bears against the adjacent face Aof the w'eb of the H-shaped member comprising the support 2. The shaft 6 is suitably moved into such position that its inner end contacts the support 2 by means of a hand- 5 wheel 1'.
I'On its top, and at its end which is most adjacent the sheet feeding mechanism generally indicated at I, the carriage 3 is provided with a pair of trunnion members 8 which support an l0 air cylinder 9, the piston of which extends away from the sheet feeding mechanism I. The end of the carriage 3 `which is remote froml the sheet feeding mechanism I 'is provided with a pair of downwardly extending members I0 between which 15 there is disposed a pin I2. The pin I2 carries a bifurcated lever I3 having downwardly ex-' tending portions I4 and longer and upwardly extendingportions I5 which are connected to the outer end of the piston rod I6, as shown at Il. 20 This bifurcated lever I3 forms a bell-crank by way of being provided with short right angular- 1y extending portions I9.
The pin I2 carries a pivotally mounted downwardly extending plate member 20 which forms 25 the piler end stop, per se, of the present invention. It will be seen that when air is admitted to the inner side of the piston in the air cylinder 9, the piston rod I6 will be forced outwardly, whereby the short downward extensions I4 on the bifur- .3 cated lever I3 will permit the plate 20 to hang in true vertical position. When, on the other hand, air is admitted to the side of the piston in the air cylinder 9 which is remote from thesheet feeding mechanism I, the piston rod I6 is moved within the air cylinder 9, whereby the bifurcated lever I3 is drawn in the same direction and the short downward extensions I4 thereof will raise the plate 20 to substantially true horizontal position.
1 When in this position, the sheets previously piled 40 may be readily withdrawn by a suitable conveyor while in their piled condition. In order to assure 4the vertical dependence of the plate 20, when in its capacity as piler end stop, the plate 20 carries a pair of aligned eye-members 22 within which 4 there is disposed a reciprocable bar 23. The lower end of this bar 2'3 is provided with a plate member 24 to which there is connected a pair of downwardly extending pins 25. Beneath the support 2 and extending longitudinally thereof there is disposed a plate 30 which forms a base for Ythe sheets being piled. This plate 30 is provided with a series of apertures 3| `within which the pins 25 on the plate member 24 are adapted to fit, thus rigidly holding the plate 20 in its true vertical 55 position. To the short extensions Il o! the bif cated lever I3 there is connected the upper end of the reciprocable bar 23 as shown at 32. The disposition of the downwardly extending short extensions I4 of the bifurcated lever I3 with respect to the plate 20 is such that the bifurcated lever I3 is permitted a short movement before they pick up plate 20 to move the same into horizontal position. This freedom of movement of the bifurcated lever I3 in advance of the contact of its extensions Il with the plate ,2l permits the short extensions I9 of the lever I3 to move the reciprocable bar 23 upwardly thereby disengaging' the pins 2'5 from the apertures 3| in the plate 30.
From the foregoing, it will be seen how the control of air into the cylinder 9 on either side of the piston therewithin will quickly operate the piler end stop of my invention in such .manner that the plate 20 occupies either a horizontal position whereby a pile of sheets may be quickly removed by a suitable conveyor; or a verticalposition, wherein it is rigidly locked against displacement by movement of the sheets thereagainst.
While I have shown and described one specific embodiment of the present invention, it will be seen that I do not wish to be limited exactly thereto, since various modifications may be made without departing from the scope of the invention, as defined by the following claims.
I claim: l. In combination with a sheet feeding mechanism, a piler end stop comprising a bed adjacent the delivery end of the sheet feeding mechanism, a carriage disposed above said bed, a vertically depending plate pivotally connected to said carriage, means carried by said plate and cooperating with said bed for locking said plate against pivotal movement, means mounted on said car-1 riage for moving said plate into a substantially horizontal position, and means operated through said last -named means for releasing said first named means.
2. In combination with a sheet feeding mechanism, a piler end stop comprising a bed adjacent the delivery end of the sheet feeding mechanism, a carriage disposed above said bed, a vertically depending plate pivotally connected to said carriage, slidable means carried by said plate and cooperating with said bed for locking said plate against pivotal movement, means mounted on said carriage for moving said plate into a substantially horizontal position, means operated through said last named means for releasing said first named means, and means for adjusting the position of said carriage with respect to said sheet feeding mechanism.
