PIVOTABLE MAGAZINE FOR WORKPIECES The invention relates to a pivotable magazine for storing workpieces provided with a bore and having for its purpose the feeding of workpieces to a treatment device such as an inductive heating system, for example, a hardening system.
When rough, wrought or cast workpieces, apart from other treatments are subjected to boring it it is advantageous to carry out first the preliminary or final boring so that during the further treatments the workpieces can be stored, orientated and clamped by means of these preliminary or final holes.
Such workpieces can he slipped onto the treatment or clamping devices manually or, in the case of automatic feed, from the store, mechanically, hydraulically, pneumatically or in a different manner.
In most cases such parts are arranged in the magazine so that the workpieces whose sole worked part, the bore, has to be left free for insertion into the device will be orientated by adjacent, but rough surfaces. In this case the various tolerances of the workpieces, which depend upon various, often uncontrollable factors, may have a very disturbing effect.
Arrangements are known in which this disadvantage is sought to be avoided by butting the workpieces separately on receiving studs (one per workpiece) of magazine chains or stars, which convey each workpiece at a given rate in front of the treatment or clamping device. The transfer of the workpiece to the clamping device is carried out, as stated above, mechanically, hydraulically, pneumatically or in a different manner.
This an'angement is safer than that mentioned before, but it is very complicated owing to the great number of receiving members and to the mechanism and electrical control system required for synchronization with the treatment process.
The purpose of the invention is the elimination of these disadvantages. The pivotable magazine according to the invention is characterized by a carrier piece adapted to pivot about a pin, in which one or more rods are fastened so that free ends of the rods of equal lengths extend on both sides of the clamping piece, and wherein each free end alternately occupies a position for stringing the workpieces thereon and for transferring its workpieces for further treatment.
This provides the advantage of mechanical simplicity with an increased reliability in operation.
The invention will be described more fully with reference to the drawing.
FIG. 1 shows the basic structure of aninductive hardening system in a plan view.
FIGS. 2a, 3, d and are side elevations of the magazine in accordance with the invention in various operational positions.
FIG. 2b is a sectional view taken on the line AB in FIG. 2a.
The operational positions shown in FIG. 2a include stringing the workpieces 12 on the receiving rod 13, elevation of a switching plate 25 and the adjustment of the receiver 23 for the workpieces 12, held by a spring arrester 19.
FIG. 3 shows the separation of the workpieces 12 by angular levers 22.
FIG. d is relevant for showing insertion of the separate workpiece by an inserting member 24 while the angular lever 22 returns to its initial position.
FIG. 5 shows the inserting member 24 returned to its initial position, the switching plate 25 being lowered, the workpiece is on receiver 23 and turns into the operational position. The switching plate 25 is ready' for switching.
The inductive hardening system (FIG. 1) is a switching plate machine comprising six clamping devices I to 6. The magazine 7 serves to feed one workpiece at a time to the clamping member 8 occupying the receiving position. The FIG. shows schematically the high-frequency generator 9, the hardening station 10 and the ejector 11.
The magazine comprises essentially a-receiving rod 13 corresponding to the pickup hole of the workpiece 12, said rod being held at the center by a clamping member M so that two e ual halves 13p and 13b are fonned. The clamping member 1 IS rotatably ournaled by a pm 15. The bearing is such that the receiving rod 13 in the operational position is inclined at an angle of about 30 to the horizontal plane. A stop disc 17 arrested by the stop lever 16 holds the clamping member and the receiving rod in this position.
The workpieces are slipped onto the upwardly inclined half 1130 of the receiving rod 13. The rail 18 guides the workpieces into the correct positions. After the workpiece has overcome the resistance provided by the arrester 19, it slides by its own weight downwards against the clamping member 14. When the magazine is filled, the clamping member 14 with the receiving rod 13 can be turned through after the arrester is disengaged. The control by the final switch 20 prevents any unintentional movement of the machining part.
Whilst the empty half of the receiving rod 13 pivots obliquely upwards, the filled half is held in front of the clamping device 8. By their own weight the workpieces again slide down, but the arrester 19 prevents a premature emptying of the magazine. I
FIG. 3 shows the singling out of the workpieces. A compressed-air cylinder 21 shifts a workpiece via an angular lever 22 past below the arrester 19. The other workpieces slide on the arrester 19. g
If the separate workpiece does not slide by its own weight to the receiving stud 23 of the clamping member 8, it is shifted completely onto it by an inserting member 24. The movement of the inserting member is illustrated in FIG. 4.
FIG. 5 illustrates the delivery of the workpiece 12 from the rail 18 by lowering the switching plate 15, the forward step of the plate and the return movement of the inserting member 24 to the initial position.
l claim:
1. A device for the gravitational feeding of workpieces comprising at least one inclined rod for slidably accommodating workpieces, said rod being pivotably mounted at a pin and attached at its midpoint to a clamping member, the free ends of the rod alternately occupying an elevated position for receiving workpieces and a lowered position for feeding workpieces as the rod is rotated about the pivot, a biased arrestor member in cooperating relationship with the rod for controlling the feeding of the workpieces, and lever means mechanically linked to the arrestor member for moving said arrestor against the biasing force to individually release the workpieces.
2. A device for the gravitational feeding of workpieces as claimed in claim 1, further comprising a movable inserting member mounted adjacent to the rod, said inserting member having a finger portion in cooperating relationship with the rod such that movement of the inserting member will cause the finger portion to engage a stationary workpiece and remove same from the rod.
