INVENTOR JOHN W MALLOPY BY f 00 29 I W W %TTORNEY5 Unite States Patent APPARATUS FOR STACKING' PLATES John W. Mallory, West Hartford, Conn., assignor to The Parker Stamp Works, Inc., Hartford, (Icon, 2 corporation of Connecticut Application February 1, 1955, Serial No. 485,565 3 Claims. (Cl. 271-87) The present invention relates to apparatus for stacking plates or platelike objects successively one below the other.
The principal object of the present invention is to provide apparatus for stacking plates in the aforesaid manner, which is simple and inexpensive in construction, which is completely automatic in operation and which is capable of effectively stacking plates at a rapid rate.
Other objects will be in part obvious, and in part pointed out more in detail hereinafter.
The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereafter set forth and the scope of the application of which will be indicated in the appended claims.
In the drawings:
Figure 1 is a perspective view of a machine provided with a plate-stacking mechanism constructed in accordance with the present invention;
Figure 2 is an enlarged front elevation view of the structure shown in Figure 1;
Figure 3'is a view similar to Figure 2, showing an initial phase in the cycle of operation of the stacking mechanism; and
Figure 4 is a view similar to Figure 3 showing a later phase in the cycle of operation.
Referring to the drawings, a plate-stacking apparatus constructed in accordance with the present invention is illustrated in connection with a machine for stamping nameplates. The machine includes a longitudinally extending bed 2 and a stamping head 4. To the right of the stamping head 4 is a supply magazine 6 which holds a stack of unstamped plates 10, and through an opening 12 in the bottom of which plates are successively fed beneath the stamping head by a reciprocal push bar 14. After stamping, the plates are transferred to a stacking magazine at the left of the stamping head by a flap 44 pivotally mounted on a pusher 42 carried by a reciprocal slide 38. The stacking magazine consists of a pair of longitudinally spaced angle-shaped upright posts 18, 20 supported on the bed and arranged to hold a stack of plates. The post 20 nearest the stamping head is cut away at its lower end to form an entrance 22 for the magazine, which is aligned with the surface of the bed. At the lower end of the other post 18 the bed has an upstanding shoulder 24 which faces the entrance 22 and together with the post 18 forms a stop for plates delivered into the magazine.
In accordance with the invention, there is provided in a recess 30 in the bed beneath the stacking magazine a ratchet roller 32, the teeth 34 of which extend the width of the bed. Each of the teeth is of such a length that when rotated to its uppermost or zenith position it extends above the surface of the bed sufliciently to engage and support the bottom plate in the stacking magazine 16 with its trailing edge above the entrance to the magazine, as shown in Figure 2. Each tooth has a radial trailing face 36 which in this position is disposed normal to the surface of the bed and is adapted to be engaged by the leading edge of a plate fed into the magazine by the slide.
Arranged to cooperate with the roller 32 is a block or projection 46 on the left-hand end of the slide. The block forms an upstandingshoulder 48 which, during movement of the slide in a right-hand direction, engages the trailing face 36, of the lowermost tooth on the roller and rotates'the roller counterclockwise to a position such that when the slide is at its extreme right-hand or platereceiving position one tooth of the roller will be disposed in its zenith position. The block also forms an upwardly facing shoulder 50 which in the plate-receiving position of the'slide engages the leading face of the tooth next adjacent the lowermost tooth, as shown in Figure 3, and locks. the roller 32 against rotation.
In the operation of the apparatus, as the slide moves to the right, the block turns the roller so that one tooth moves to its zenith position and tilts the plates in the magazine so as to elevate the trailing edge of the bottom plate above the'magazine entrance 22. The engagement of the shoulders 48, 50 with the leading and trailing faces of adjacent teeth on the roller locks the roller against rotation during operation of the stamping head and holds the zenith tooth in proper plate-receiving position. The push bar 14 moves a plate from the supply magazine 6 to stamping position by passing it beneath the pusher 42 and pivotal fiap 44. After the plate is stamped, the slide moves to the left and the pusher 42 moves the plate from beneath the stamping head and feeds it into the entrance of the magazine 16.
As the plate is pushed through the magazine entrance 22 its leading edge slides freely beneath the trailing edge of the upraised bottom plate in the magazine and engages the trailing face 36 of the zenith tooth. As the slide continues to move to the left, the plate rotates the roller sufiiciently to slide easily over the top of its teeth 34 and move completely under the stack. The partial rotation of the roller which takes place as the freshly inserted plate passes over it, displaces the next tooth in turn on its underside into the path of the block 46 so that, as the slide returns to the right, the shoulder 48 engages this next tooth and indexes the roller enough to move another tooth to its zenith position, thereby conditioning the magazine for the smooth reception of the next plate.
Thus it may be seen that the invention provides an efiective and automatic mechanism of simple construction for rapidly stacking any desired number of plates. While the invention has been illustrated in connection with a plate stamping machine, it will be understood that this particular application is by way of illustration only, since the stacking mechanism is manifestly suitable for stacking a variety of plates or platelike objects.
As many changes could be made in the above construction and many apparently widely diiferent embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
I claim:
