7 Claims.

This invention relates to a mechanism for receiving ware from a machine, such as a glassforming machine, and for delivering it to another apparatus such, for example, as a lehr, and has for an object to provide such a set-over mechanism as is capable of being employed with a continuously rotating forming machine such, for exampie, as the forming machine illustrated and described Moorshead No. 1,807,857 of June 2, 1931.

A further object is to produce a set-over mechanism of simple but rugged construction which occupies a minimum of floor space and is effective in the operation of receiving Ware from one machine and delivering it to additional apparatus either for further processing, packing or storage.

These and other objects which will be made more apparent throughout the further descripticn of this invention and are obtained by means of apparatus such as illustrated in the drawings accompanying and forming a part hereof,

In the drawings, Figure l is a diagrammatic plan view of apparatus embodying my invention shown in association with a finishing mold and a knock-out arm;

Fig. 2 is a fragmental view diagrammatically illustrating one relationship between finishing mold, knock-out armand ware-receiving trough, in which a portion of the finishing mold is shown in section for convenience of illustration;

Fig. 3 is a vertical sectional view of the setover mechanism diagrammatically shown in Fig. l, the section. being taken along the line III-III of Fig. 1;

Fig. 4. is a side elevation of a composite troughcarrying member such as forms a part of the apparatusill'ustrated in Figs. 1 and 3 with a portion thereof shown in section for convenience of illustration; and

Fig. 5 is a plan view of the member shown in Fig. 4. and associated with a dotted line diagram illustrating one phase of the movement of the member.

Set-over mechanisms employed in connection with glass-forming machinery are necessarily so arranged that" they efiectively handle hot glass articles without mar-ring them. The problem occasioned by this type of service is to some extent increased where the glass-forming machine includes a continuously rotating mold carrying table from which the ware discharged or delivered during rotation of the table. From the foregoing, it will be apparent that an object-of my invention is to produce an efiective set-over in United States patent to mechanism which iscapable of cooperating with a continuously rotating forming machine and which itself receives and delivers ware while the ware-receiving receptacles thereof are in motion.

The apparatus illustrated as an embodiment of my invention includes a number of ware-receiving receptacles shown in the form of open-ended troughs each so mounted and arranged that each receptacle occupies an article-retaining position and is, in effect, moving with a discharging finishing mold at the time of receiving a glass article therefrom. This movement of the receptacle continues after the article is received thereby but the continued motion is such as to clear all moving and other parts of the forming machine. The receptacle is then actuated to deposit the article carried by it and, in the mechanism illustrated, this is accomplished by moving the trough-like receptacle from a horizontal to a substantially vertical position with the open end of the trough lowermost. This re-adjusting of the position of the trough takes place as the trough is moving and, consequently, the apparatus involves means for receiving the delivered article while that article is moving. I also contemplate employing cooperating conveyors for continuing the movement of the article after it is no longer under the control of the moving receptacle or trough.

Each article receiving receptacle is carried at heend of an arm-like member and these members are carried by a rotatable table, which is rotated at such a speed as to move the article receiving receptacle at the same speed as the finishing mold of the associated forming machine during the operation of setting over ware received therefrom, One such receptacle and supporting member is provided for each finishing mold of the forming machine and the armlike members are adapted to be moved to radial positions during the operation of receiving and depositing ware. Each such arm swings downwardly to an inoperative position during its cycle and consequently it may be stated that each article receiving receptacle is alternately extended and retracted during its cycle of operation.

Referring more particularly to Figures 1 and 3, a central, table-supporting column 6 is rigidly secured to a base I which is in turn carried by a sub-base 8. The sub-base 8 is mounted on a foundation structure 9 by means of four adjustable posts It), each of which is shown in the form of a screw and is threaded into the sub-base and mounted on a thrust bearing carried by a foundation member 9. Each such screw post is provided with a sprocket |2 which is engaged by a chain |3 looped around and engaging all of the sprockets for the purpose of simultaneously turning all posts It! to raise or lower the sub-base and thus adjust its position with relation to the operating forming machine. One screw post I0 is provided with an extension I0 which is preferably squared or otherwise adapted to receive a hand-wheel M for turning it and consequently all of the other supporting posts through the agency of the sprockets l2 and chain l3. With this arrangement the sub-base 8 may be accurately positioned at the desired height above the foundation members and consequently the height of the set-over mechanism may be accurately adjusted with relation to the associated forming machine.

The base is supported on the sub-base through the agency of parallel rails l5, shown as angle irons, and flanged wheels l6. The rails |5 are secured to the sub-base 8 and the flanged wheels are secured to the base 1 in such relationship that they engage the rails l5, provide for movement of the base therealong, and also define the lateral position of the base by reason of the engagement of the flanges with the rails. It will of course be understood that at least four flange wheels are provided for supporting the base and that each is journaled in a bearing carried by the base I.

The base is moved longitudinally of the rails |5 by means of a gear l1 and rack l8. The rack is secured to the lower face of the base I, preferably at a point midway between the rails l5 and extends parallel to these rails. The sub-base 8 is apertured to accommodate the rack and the engagement between it and gear H. The rack and gear are shown in dot-dash lines for the purpose of indicating that their positions with relation to the plane of the sectional view are to some extent optional. As thus diagrammatically illustrated, the gear is carried by a shaft supported in suitable bearings (not shown) which may be carried by the foundation members. The shaft is adapted to be turned by a handle 20 for the purpose of shifting the position of the base I along the rails I5. A pawl and ratchet connection may be provided between the handle 2 and the shaft I? so as to facilitate the operation of the rack and gear connection.

A sleeve 2| is telescoped over the central column 6 and is carried by that column through the agency of a ball bearing 22. As shown, the lower race of the bearing 22 is carried by an upwardly faced shoulder of the non-rotatable column 6 and the upper race of the bearing supports a table 23 which is rigidly secured to the sleeve 2| and is so formed that it in efiect provides a re-entrant flange for the sleeve 2| which engages and is supported by the upper race of the bearing 22. The column 6 is provided with an extension 6, shown formed in two diameters, and which provides a support for a non-rotatable table 24 located immediately above and concentric with the rotatable table 23. The table 24 overlaps the table 23 and, as will be described, provides a support for cams which cooperate with and actuate mechanisms carried by the table 23.

The sleeve 2| is driven by a drive shaft 25 through the agency of bevel gears 26, 21, a stub shaft |8 journaled in a bearing carried by the base I, a gear 29 and a gear 3|]. One last mentioned gear is shown secured to the lower end of the sleeve 2| and surrounding the central column 6. It will be apparent that the stub shaft 28 and its bearing projects downwardly through a suitable aperture provided in the sub-base 8 and so arranged as to accommodate the relative movement between the two bases 1 and B. It will also be apparent that the bevel gear 26 is splined or otherwise secured to the shaft 25 so that it may be adjusted to accommodate this relative movement.

The apparatus diagrammatically illustrated in Figure 1 is designed to serve an eight-mold forming machine and is, therefore, provided with eight ware-receiving receptacles, each of which is generally designated by the numeral 3|. Each receptacle 3| is carried by a composite member or arm 32 and for convenience of illustration one such member is omitted from Figure 1 but the position of its supporting bracket 33 is shown in dotted lines. Each bracket 33 is secured to the rotating table 23 and overhangs the edge of that table. As shown more clearly in Figs. 4 and 5, each member 32 includes a hinge plate or support member 34 and a carrier arm 35 on which the ware-receiving receptacle is mounted. The receptacle 3| is shown in the form of a trough closed at its inner and open at its outer end. As will be described, the trough is tiltable to different positions and this movement is controlled by a trough-actuating plunger 36 and a troughholding spring 3'! which resists the movement of the plunger.

The plate or support member 34 is carried by a hinge pin 46 which in turn is carried by the bracket 33 and the arrangement is such that the plate or support member 34 may swing about its supporting pin and occupy a substantially vertical position, as shown at the right-hand side of Figure 3, or a substantially horizontal position, as shown at the left-hand side of Fig. 3. This swinging movement of the plate or support member, and consequently of the parts carried by it, is controlled by a stationary cam track 42 which is carried by the base I and encircles the central column 6. As shown, the plate or support member 34 is provided with a cam roller 43 which engages the cam track 42.

The arm 35 is pivotally secured to the plate or support member 34 by means of a pivot pin 44 which is carried by said plate or support member. The arm is normally held against an adjustable stop 45 by means of the spring 38. As shown, the stop 45 is in the form of a bolt carried by an appropriately threaded lug 46 formed on the plate 34. The position of the bolt with relation to the lug 46 is readily adjustable and may be fixed more or less permanently by the lock nut 41. Arm 35 is normally held against the stop 45 by means of the coil spring 38 which operates between a lug 48 carried by the plate or support member 34 and a lug 49 carried by the arm 35. Thus, the arm 35 is capable of pivoting about the pivot pin 44, and is normally yieldingly gield against the stop 45 by means of the spring The ware-receiving trough 3| is pivotally secured to a bracket 5| which is rigidly secured to the end of the arm 35. As shown in Fig. 4, the trough 3| tilts about a pivot pin 52 carried by the bracket 5|, and is normally held in ware-receiving position by the spring 31 which operates between a lug 31' carried by the plate or support member 34 and a lug 3| carried by the trough 3|. This spring normally holds a finger 53 carried by the trough in engagement with an adjustable stop Fad-carried by the arm 35 and bracket 5|. Stop 54 is shown in the form of a screw which projects upwardly beyond the bracket 5| and is provided with a lock nut for the purpose of holding it in adjusted positions.

The plunger 3% is slidably mounted in aplunger block 55 which is suitably secured to the arm 35. This plunger is provided with a cam roller 36' which isadapted to engage a stationary cam 56 for the purpose of shifting the position of the trough 35 in opposition to the pull of the spring 3'1. The cam 56 is carried by the stationary table 24 and the cam actuated movements of the plunger itfiare imparted to the trough by means of the link 5 one end of which is pivotally secured to the trough by means of pivot pin 51' and the other end of which is pivotally secured to the plunger 36 by means of a pin 5?. This last-mentioned pin is carried by a bifurcated member 58 which is adjustably secured to the plunger Stby means of a screw shank with which it is provided. The shank is threaded into the end of the plunger 3% and is held in place by a lock nut 59 The plate-like arm 35-is provided with a finger M for periodically swinging it about the pivot pin M. As shown, the arm is provided with a cam roller 6i and is adapted to periodically engage a stationary cam 62 as the table 23 turns and as the arm 35 revolves about the column. The cam 82 is carried by the stationary table 2?- and is so formed and positioned that its effect is to momentarily accelerate the angular velocity of the associated receptacle St for the purpose of clearing an operating part of the forming machine, I

i. e., a part associated with the finishing mold which has just discharged an article.

In Figs. 1 and 2 I have more or less diagrammatically shown a finishing mold of the associated forming machine and the positions it momentarily occupies with relation to an article receptacle 3!, just prior to delivering an article to the receptacle and also just after such a delivery has been accomplished. These molds are usually three-part molds in that they include two sections hinged together which. cooperate with a base section to form the mold cavity when the sections of the mold occupy the position ordinarily termed the closed position. In Figs. 1 and 2 the finishing mold is illustrated as including two hinged sections 65 and a base section 65a. It is also illustrated as associated with a knock-out arm 56. This arm is pivoted to swing about a pin 66 carried by the forming machine and is provided with a head 66 adapted to engage a finished article t3 and. hold the article in place on the base 65a of the mold as the hinged sections 65 are opening.

Thus it will be apparent that the knock-out device associated with a finishing mold engages the. exposed. upper edge or lip of the finished article as the blow mold, enclosing that article,

moves toward the article-delivering station. This ceiving receptacle will, in effect, move together throughout a short sector of their travel and at the instant of transferring the article from th mold to the receptacle. It is, of course, apparent that the movement of both the mold and the receptacle must continue after the transfer is accomplished and it will also be apparent that the finishing. mold must be repositioned in order to receive the next successive parison. In a forming" machine such as previously mentioned, a continuation of the normal movement of the receptacle 3 1- will cause it to collide with an operating part of the forming machine. For that reason the cam GZ actin-g through the cam roller El and the finger 6| momentarily turns the plate-like arm 35 about the pin M in opposition to the-pull of the spring 38'. The cam is so shaped that as the roller 61" moves along it, by reason of therotation of the table 23', it permits the i spring 38 toretract the plate-like arm 35 so that it again engages thestop Q5 with the result that the movement of the associated receptacle 3! is momentarily controlled, 1. e., by the cam 62 in order toinsure proper functioning of the mechanism.

The cam track 4-2, for controlling the swing of. the composite arm 32 about the pivot pin A0, is supported by the base 1' on one or more struts 42. As shown, the cam track #32 surrounds the column 6 and the rotating sleeve 2!, and the strut 42 is mounted on a casing 5a carried by thebase l and enclosing the actuating gears of the sleeve 2|.

Referring to Fig. 1, a stationary arch-shaped slide EBis'a'ssociated with the set-over mechanism and" in such relation as to receive the articles Bl as'the receptacles 3i are tilted in response to the action of the cam actuated plungers 36-. As

:lown, the slide is provided with a guiding flange 38' which cooperates. with each tilting and tilted receptacle: 3!" in guiding an article along the slide and onto a conveyor belt 58. The belt 69 is carried by standards at least one of which-the standard ii-is. supported on the base 7. Conveyor 69" is. of ordinary construction and, as

shown, is driven by a shaft T2 through the agency of sprockets l2" and. a chain it. The shaft it! is journaled in. hangers formed on the base I and is driven by the main drive shaft 25 through the agency of'the bevel gear 26 and a bevelgear M. Articlev guides 68 and 63a are associated with the. conveyor belt til in such way as to direct the travel of articles along, the belt and onto a rotating conveyor table '55 from which they may be. delivered to a second conveyor belt it.

Reference. to Figure I discloses that after each composite arm 32. moves to such a position that the cam roller Bl. thereof no longer engages the cam 52' and. consequently after. the plate-like arm 35' has re-adjusteditself against the stop 45, the associated: cam roller 36 moves into contact with thezstat-icnary cam 56. This takes place at about the time the associated receptacle 3t moves 'over the stationary slide (it. and, as a. result, the plunger 36; is moved outwardly to tilt the receptacle through. the. agency of the connecting rod Inspection ofthe drawings discloses thatthe 56 is so contoured that the tilting of each receptacle-3 i is ace-emplished quite gradually and is completed only after the receptacle moves to a position above the conveyor belt. That is to say, each receptacle. is gradually tilted to-thearticle discharging position and this movement is completed only after the receptacle has moved the associated article 61 along the slider 68 and onto the conveyor belt 69. Cam 56 is so contoured that it permits the spring 31 more or less gradually to return the receptacle to the article receiving position with relation to its carrying arm 35 and bracket 5! as the receptacle swings away from the conveyor 69.

After each composite arm 32 has propelled an article such asa bottle onto the conveyor belt 69, it continues its rotation in an extended position until it and all parts carried by it clear the conveyor. As this position is reached the cam roller 43 rides down an inclined portion 42a of the cam track 42 and thus permits the composite arm to swing downwardly around its hinge pin 49. The cam track is so formed that the composite arm 32 moves downwardly to an almost vertical position and remains in that position as it swings through approximately 180 of its travel around the column 6. During this travel the roller 43 may bear on the portion 42b of the cam track. As each arm 32 approaches the article receiving position its cam roller 43 rides up an inclined portion 420 of the cam track, thus lifting the hinged portion of the arm to a substantially horizontal position. Thus it is apparent that each article receiving receptacle 31 is alternately retracted and extended with relation to the center about which it revolves and that it arrives at the extended position immediately before receiving an article and continues in that position as it moves to convey that article toward and onto the moving conveyor 69. During this last mentioned movement its revolving movement around the column 6 is modified by the action of the cam 62 and in the particular embodiment this modification consists of a momentary acceleration followed by a corresponding deceleration.

From the foregoing it will be apparent that I have produced a new and improved set-over mechanism which is capable of functioning effectively in receiving articles from a continuously rotating glass-forming machine and in setting over articles so received. In addition, the set-over mechanism is so constructed and operated that the moving parts thereof are caused to perform their individual functions while continuously revolving about a central column or a fixed axis. In this connection each article-receiving receptacle is so actuated by a rotating device, such as the table 23, that it continuously moves around an axis of revolution although this linear velocity is modified both by moving it toward and from the axis of revolution and by periodically accelerating and decelerating its angular velocity. The first-mentioned control is accomplished by the cam track 42 through the agency of the cam roller 43 and the last-mentioned control is accomplished by cam 62 and cooperating parts. It will also be noted that the associated devices and instrumentalities are so arranged that each trough-like receptacle 3| is cam tilted to a position at an angle with its carrying arm for the purpose of delivering an article contained therein, that the delivery is not completed until each article moves onto a mechanically actuated conveyor and that the receptacle carrying arm then swings about its hinge pin to retract the receptacle or to move it closer to its axis of revolution.

While I have described but one embodiment of my invention, it will be apparent that various changes, additions and modifications may be made in the structural details thereof without departing from the spirit or scope as defined by the appended claims.
