14 Claims.

The invention relates to a discharging apparatus, and particularly to an apparatus for discharging stock from machine tools, for instance cutters and saws, from which continuously or intermittently fed and treated articles, for instance rods, bar's, billets, tubes and the like, are to be removed in conformity with the feed.

The invention is more particularly concerned with apparatus which upon delivery of the stock from the Working machine are lengthwise displaced for the final discharge.

It is an object of the invention to combine the lengthwise displacement of the discharge apparatus with a movement resulting in the final removal of the treated stock.

It is a further object of the invention to automatically control the discharging procedure.

It is another object of the invention todirect the discharge of the treated stock in such a mannor that its removal is effected in a substantially perpendicular direction to the lengthwise displacement of the discharge conveyor.

It is also an object of the invention to effect the entire discharging operation by means of a single power source.

,It is another object of the invention to simplify the discharging procedure whereby an exceedingly quick and unobstructed removal is accomplished.

With these and further objects in View which will become apparent as this specification proceeds, the invention will be hereinafter described with reference to the accompanying drawings which illustrate certain preferred embodiments of the same, without, however, limiting its construction or application.

The discharging apparatus is by way of example illustrated in the drawings in cooperation with a rotary saw; however, it is understood that the apparatus may be associated with any other working machine, such as a machine tool, to receive stock therefrom and to finally discharge the same.

Fig. 1'7 is a similar elevation but showing the parts of Fig. 16 in a discharging position, and

Fig. 18' is a part sectional elevation on a reduced scale, showing two operating positions of the discharge conveyor.

In the embodiment shown in Figs. 1 to 8 the discharging apparatus is functionally combined with a rotary cutter A.

The cutter A is provided with a roller conveyor I03, Fig. 2, to conduct billet 6 into the cutter. The cutter is also provided with a rotary saw blade 2, a clamp or vise l'0l and a support I02 for the billet, the latter being firmly held by the vise during the severing operation.

The discharging apparatus mainly comprises a supporting body 3 preferably of tubular cross section, a movable frame 5 surrounding support 3, a plurality of conveyor rollers 4 mounted in movable frame 5 to form a. conveyor race receiving the cut stock'fi, and a device to longitudinally displace frame 5 including a fluid operated cylinder I. The supporting body is rigidly mounted on supports 8 (Figs. 3, 4, '7) in amanner which will be described hereinafter.

The conveyorrollers 4 having, for instance, a

concave shape are rotatably supported in the ver-' I -driving cylinder 7.

In the embodiment illustrated. in Fig. 2, a sec- .,ond guide element I8 is located in a part of frame instance, consist of end sections of a pin mounted in tubular body 3.

Rollers H) are rotatably located in the walls of frame above projections H and carried on these projections. In the initial position of the discharging apparatus shown in Figs. 1, 2 and 3; 1 frame 5 is suspended on tubular body 3 by means of rollers 53 and projections ll.

As apparent from Figs. 1 to 3, the rollers l3;

and the projections H are arranged in such a manner that in the initial position of frame 5, which is the position closest to saw A the rollers Ill are supported on top of projections 4!, thus bringing rolls 4 out of contact with body'3 in this position the rolls 4 rotate freely in frame 5.

The cylinder 1 is preferably'arranged coaxially with the tubular body 3 and is provided with a double acting piston H1, the pressure medium being admitted at opposite e'ndsof the cylinder through- tubes 33, 34, Figs. 1, 2 A rod l2 rigidly connected with piston II! extends into the hol -1ow interior of tubular body 3.

As particularly shown in Figs. Band 6, piston --rod 12 has a reduced portion I3 which is engaged by the forked end H! of a guide element l5; Guide element I5 is rigidly fixed to the movable frame 5;.the'middleportion thereof is provided with a rotatable ring it held in position by the Wall of frame Eiand by a collar H6.

Ring lfi'en'g'ages a slot l1 located in the tubular b-OdySIf'The slot [1 is composed of a straight vfrjont portion parallel to the longitudinal axis of body 3 and acurved rear portion nearer to the 5 situated closer to saw A engaging a'slot similar to slot ll of body 3 and having the same configuration as slot I]. Additional guide elements [and slots maybe. provided if desired' When the movable frame' is-displaced in the longitudinal direction, the guide pin [5 rotates, the frame about the longitudinal centroid of tubular body 3. A longitudinally adjustable device is provided I in order to interrupt the feed of billet 6 into the saw at a predetermined length; this stop device .is'illustrated'in detail in Figs; 8 and 9, Fig. 8 illustrating the normal position of the stop and Fig; 9 showing its position when the frame 5 has been rotated during its longitudinal displacement; the stop consists of a housing 2| which is slidable on one side wall of frame 5, portion 22 of thehousing engaging the inner face of this side wall. The outer face of the side wall is engaged by a wedgemember 23 which contacts an inclined face 24 of housing2l. A screw 25 hav-' ing a knob 25. extends through the housing into {a threaded hole of wedge 23 in such a manner v thatby; turning knob 36 the device may either be fixed to frame 5 or be releasable for lengthwise adjustment. A stop lever '21 is pivotally confnected tohcusing 2.! through a .pin 28; it has a projecting portion 29 which is contacted by the endure piston 33 movable ina cylinder portion 3| of 'housing 21-. i l i The lever 27 islifted upo'r advancement of piston 33 under the action of a pressure fluid-introduced into cylinder 3! through aiixablehose 32.

move downwardly by gravity.

The movement of piston 30 is initiated immediately upon the admission of a pressure medium, whereas the movement of piston 10! is commenced only after the pressure has been released through pipe 34 and control valve 36.

As shown in Figs. 1 and 2, pipes 33 and 34 are arranged to introduce a pressure medium into cylinder 1 at'opposite sides ofrpiston I 01. Hose 32 is connected to pipe .33. at 35. A preferably foot operated control valve 36 is provided to ad- I mit fluid under pressure either into pipe 33 and hose 32 or into pipe 34. When the pipes 32, 33 are charged with fluid under pressure, the pipe 34 is. automatically connected through control valve 36 to the exhaust and vice versa. V

The tubular body 3 is preferably resiliently vmounted on supports v8 as illustrated in detail in'Fig. '7.

the lower threaded end of stud 40 to limit upward movementof body 3 underthe action of spring 39.

From this description it will be apparent that tubular body 3 as wellascylinder '5 suspended thereon are resiliently, carried upon supports 8 -by springs 39 and maybe pressed down on the,

35 supports 8, the latter being located within the range of recesses 9 of the frame.

Instead of using a spring other resilient means maybe provided, e. g. a rubber cushion or fluid .rangement'is preferably such that the clamp veyor is effected simultaneously.

A suitable receptacle, such as a'truck, may be a provided to receive the disch arged stock from the conveyor.

Th operation of the above described apparatus is, as follows:

Billet 6 is introduced into saw A from the left side of Figs. "1 and -2 and is transported by con- .veyor I03 and discharge conveyor rollers 4 until the billet engages stop lever 21 of the stop deyice 20.

-The stop hasbeen adjusted; lengthwise of frame 5 insuchaimanner that awork-piece of a desired length will be severed from the stock upon operation of the saw. V

Nutsg42, 43 havebeen; adjusted so that springs 39 lift the discharge conveyorto a position in which the upper facesof rollers 4 contacting the work-piece are slightly higher than th 'upper .face of the supporting block 102. Theclampis now actuated; the actuation of the clamp causes the discharge conveyor to be moveddownwards against the action of springs 39. I The resilient mounting of the-discharg conveyor thus permits, within predetermined limits,

an automatic adjustment of the'fle'vel of the con-J eter. Th retraction of the discharge conveyor from the initial position may be also effected by lconnectingthe. pressure source actuating the clamp with a device suchas the differential pisi n I a h h. melee, -9l QOWWFICL.

' This 'movementcauses rollers ID to roll off from projections" ll so that the frame will slide downwards. untirth'e concave rollers 4 contact body 3}" during 'the displacement of piston II! the concave rollers-'4 will roll upon tubular body 3;] their peripheral speed being substantially twice the linear speed of frame 5.

From the previously. given description. of the stop mechanism it will be clear that when piston II! is actuated, pressure is simultaneously introduced through hose 32 into cylinder 3 l vto advance piston 30' and-lift stop lever 21. The release of the. stop which occursbefore piston ll'l commences to move allows a movement of thecut length of stock relatively to and faster than fram due to the greater peripheral speed of the rolls 4.

As will be particularly apparent. from Figs. 5 and 6, cylinder l w-ill first cause a linear movement of frame v5, that is duringthe period of time in which the guide S-and ring I 6 are Within the straight portion of slot I1. When guide means I5 6' move along the curved portion of said slot, rotational movement is. superimposed upon the linear-movement of frame 5 so asto swing the frame into the tilted position shown in Figs; l

and 9 v 1.

Dueito this tilting movement, the cut length of stock 6 will be caused to roll orslide laterally off thewconcave rollers 4 and to bedischarged over extension-l05 of frame 5 into a;suitable receptacle. -By additional guide means which arenot connected to the pistonrod I2 a'guarantee is created that the end of frame 5 facing the machine I" properly participates in the angular -After the discharge of the cut lengthof stock, control valve 36' is actuated to'introduce pressure mm 91136534: and to p pes fl and 33 with exhaust; I

Referring now to'Fig. lfl which isgenerally similar to Fig. 3, it-maybe desirable under'certam-conditionsto adaptthe shapeof the conveyor rollers to that of supporting means I02 "of I the saw. Such modified roller shape is illustrated in Fig. IO-Wherein roller-45 comprises two conical nzportions, the: sides ofthe c0nical portions formmg approximately-right angles with one another.

The second modification of :the "discharge, conveyor is illustrated in Figs. l1,*12, 13-,;-18 inzwhich rolls 46 of cylindrical shape areprovided; such straight rollers are inexpensiveto manufacture.

The means for disengaging theeonveyor rollers from the'tubular body, in'the initialposition of the-conveyor frame have also-been modified;

The tubular body 4'!- replacing body'3 ofthe first embodiment-is provided with r ecessed portions 48 on its top. These recessed portions are spaced in such a manner on" tubularibody 46 'that in the initial position of frame 35 .e; g.in-theposition closest to the saw; each roll 46 is. disposed above one of said portions 48. l I

'Frame '49- is similarly constructed as frame 5 of the first embodiment with the one exception that it is provided with webs 50 rigidly connected theretoand arranged at certain distances intermediate adjacent rolls 46'. each web has a curved recess 5| corresponding to the cylindrical periphery of tubular body 41.

The Webs 50"and their'recesse's 5'I-are arranged in such a manner that in the initial position shown in Fig. 12 the webs contact the cylindrical surface of the tubular body 41; the framebeing suspended from said body by means 'ofthe webs 50'. The rolls 46 are in this position'out of contact with body 41' as they are-disposed above the recessed portions 48; The rolls are thus free- 1y rotatable. When the frame isdisplaced lengthwise by the driving cylinder as previously described, the rolls 46 move from the full-line position. to the dotted-line-position,- as'shown in Fig. 18, so as to engage the-cylindrical surface of tubularbody 41 and to lift frame 49 some- What, the webs 50 being simultaneously brought out-of contact withbody 41; the frame is nowin The lower "face of bodiment of the invention.

to 17' illustrate another simplified em- I The discharge conveyor comprises a jtrough shaped member 52 of angular shape which near its front end (left end of Fig. 15) is provided with a downwardly extending rib 53 rigidly connected thereto; one end of efrod 54 is'rigidly'fastened to this rib 53. rigidly connected with a coupling housing 55 Trough 52 is by means of rib 55 mounted on the other end'of rod-54, the latter' being freely movable in a bearing'57 connected,

with a frame structure 58.

Adriving device 59 similar to cylinder 7 of the first embodiment is carried by frame'58 and is provided with a'piston rod 60 disposed coaxially follow all longitudinal movements of the piston rod while the latter does not participate in tilting movements imposed upon rod 54 and trough 52.

In order to produce the tilting of the trough a guide roller BI is rotatably supported in coupling housing 56 so as to engage a stationary guide member 52 carried by frame 58. Guide member 62' is provided with a guide face 63 which includes a straight front portion and a portion inclined towardsthe driving cylinder59. Y It is to be noted that trough 52 is somewhat eccentrically disposed relatively to rod 54 so that, due to the action of gravity, the trough 52 will rotate about the axis of rod 54 in clockwise direction as seen in Figs. 16 and'17; This will keep guide roller 5| in contact with guide face 63. Slide members 64 fastened by supports 65 to frame 58 are provided to receive the material thrownoff from trough 52.

" The rear end of trough52 will be supported and guided by a rod similar to rod 54 and guiding means similar to those indicated at 6!, 62, B3. Since the structure at the rear end substantially corresponds to that illustrated in Figs. 14 to '17 except for the fact that it is not connected to a driving cylinder, it is not considered necessary to show the rear end in the drawings. 1

A stop device (not shown) for determining the length of stock may be attached to trough 52 and is preferably adjustable lengthwise thereof. This stop device would have a function similar to that of stop device 25 mentioned with reference to the first embodiment of the invention shown in Figs. 1 to 4. I

The apparatus illustrated in Figs. 14 to 17 op- .erates as follows: p

The stock to be cut is advanced in trough 52; if a stop device is provided, the stock will be moved until it contacts thestop. The cutting operation will then be performed and hereafter piston rod 60 will be moved to the right side of Figs. 14 and l5, pulling rod 54 and trough 52 along. r

When guide roller 5 I travels on the inclined portion of guide face 53, the trough 62' will be tilted downwardly into the position shown i Fig. 17 so that a severed length o-f,stock. will be dis: charged onto the slide members 64.

It will be clear that in this embodiment of the invention displacement of a stop device is not re quired during the discharge operation as'the stock 7 will not be advancedbeyond the position of the stop. V V During the return stroke trough 52is returned into its initial position; guide roller 55 travelling upwardly on guide face 63. The apparatus is then ready to receive the next length of stock.

7 The modification shown in Figs; 14 to 17 has the advantage of great simplicity and is particularly suitable in cases where conveyor rollers'for' supporting the stock are not required.
