Application June'17, 1933, Serial No. 676,301
17 Claims.
This invention relates to glassware forming machines such as glass blowing or pressing machines and more especially to bottle manufacturing machines in which a series of glass forming 5 molds is moved in a circular path, each piece of finished ware being removed when it arrives at a station to a belt which carries them away.
The principal objecto-f the invention lsto provide improved mechanism whereby the bottles or l other similar ware are automatically and rapidly removed upon completion of the pressing and blowing operation Without serious loss :by breakage of the ware or injury to the machine or parts thereof. Other objects will appear from l the disclosure herein. Y
The invention is embodied in the example herein shown and described, thefeatures of novelty being finally claimed.
In the accompanying drawings- .0 Figure 1 is a plan view with parts broken out and in section of a suflicient fraction of glass pressing or blowing machine showing my present invention embodied therein.
Fig. 2 is mainly a sectional view on the line II-II Fig, 1 with parts in full illustrating a portion of the power transmitting means.
Fig. 3 is a vertical sectional view illustrating the bottle centering and gripping devices and the mechanism for operating those devices.
Figs. 4 and 5 are elevations of the groo-ved faces 0f the left and right cams shown in the upper portion Fig. 3.
Fig. 6 is a general view partly in full `and party in section locking toward the right hand side of Fig. 1, the sectional portion at the top of this view being taken on the line VI-VI, Fig. 1.
Fig. 7 is a detailplan view, on a larger scale, 0f the take-out swinging and rotating mechanism, parts being broken out and omitted.
0 Fig. 8 is a view looking at the lower end of the take-out rotating table as seen at the right hand end of Fig. 7.
Fig. 9 is a perspective of a dog employed.
In the views A designates a base, B a center 45 column around which the molds C travel as customary in some of such machines in common use. D designates the main drive worm, E a worm gear engaged by the main drive; In the illustrated embodiment the mold carrier is moved in- 60 termittently and the gear E revolves an eccentrically located rotary block F for engaging the slots of a wheel G thereby intermittently rotating a table or carrier on which the molds are carried. The devices F and G constitute a Geneva move- 65 ment of the species illustrated in an application for patent of the United States led by me April 16, 1932, S. No. 605,680.
The ware gripping and lifting mechanism and the ware take-out mechanism of my invention are supported in a suitable frame, carried by the 5 frame A of the machine.
Bottle gripping and lifting mechanism This mechanism includes a plurality of jaws I0 (see Fig. 3) adapted to grip the bottle at the 10 exterior of its lip II," the stem of said jaws being slidable in hollow arms of bell crank levers I2 fulcrumed to ears on said lower end of a sliding tubular member I9. The other arms ofthe bell crank levers I2 are pivotally connected by means l5 of a pin and tube member I4 to ears on the upper end or head member of a sliding sleeve I3.
The jaws I0 are each yieldably mounted in the hollow arm of its bell crank lever I2 as by means of. a yspring I5, so that each jaw I0 may yield in 20 case it should strike the top of a mold and the downward movement of the jaws are each limited by a small bolt I6 extended through a slot Il in the hollow arm of the bell crank lever. A coiled spring I8 is interposed between the pin andl tube 25 of the member I4 to give cushion and safety action.`
The tubular member i9 is inserted in the axis of the sleeve member I3 and said tube I9 has at its lower end an annular shoulder between which 30 and an opposed shoulder in the upper end of the sleeve member I3 is a coiled spring 20 tending to open the jaws. i
In the axis of the tubular member I 9 is a plunger rod 2I carrying a beveled pilot member 22 or 35 centering device to engage the mouth of the bottle to keep the bottle from moving to one side when mold is opened and from falling olf `of the mold bottom. Said pilot member has a stem that extends into a tubular portion of the lower end of the rod 2|, andis provided with a groove that is entered by a small bolt 23 permitting a limited vertical and yielding movement of the pilot to prevent injury thereto in the event the mold is not properly opened. Said pilot is pressed down by a coiled spring 24 inserted between the upper end of the stem of the pilot and a cross pin in the tubular portion above so that when the plunger rod is forced down ayielding pressure is exerted on the inner side of the lip of the bottle by the pilot when the latter is entered thereagainst if oli center.
In practice the jaws are normally pressed asunder while the pilot is elevated slightly above the plane of the lip of the bottle; and to engage the bottle when it arrives under the apparatus just described the pilot is first caused to descend slightly into the bottle and then the jaws clamped against the under side of the lip. When the shovel is under the bottle the jaws leave -first and the pilot last but before the outward stroke of the shovel.
The principal function of the pilot is to keep the bottle from shifting on the mold bottom and hold it in proper position to be engaged by the gripping jaws. An important function of the gripping jaws is to insure the lifting of the bottle suiciently from its support to permit the insertion thereunder of the take-out devices to be hereinafter described.
The depression of the pilot is effected by means of a suitable cam 25 on a horizontal shaft 26 driven by suitable gearing with a vertical shaft 21, the latter extending in a fixed hollow housing or column 28, said vertical shaft 21 receiving power from a take-ofi' of the main drive D through a shaft 29 and worm gear 29 keyed on the lower end of shaft 21 (see Fig. 2). The cam 25 is provided with a groove 25a that is engaged by a roller 30 on a short shaft 3l connected with the plunger rod 2|, said shaft extending through a longitudinal slot 32 in the tubular member I9 so that the pilot can be operated by its actuating cam 25 independently of the operation of the gripping jaw tubular member I9.
'I'he gripping jaws are actuated by a cam member 33 secured on said horizontal shaft 26, said cam member 33 being provided at its rim with an excrescent portion at 33e that acts in an anti-friction roller 34 journaled in the head of the sleeve member I3. The action of said excrescent portion 33a is to throw the gripping jaws inward toward each other after the pilot 22 has centered the bottle. The cam member 33 is provided at its face with a groove 33 engaged by a roller 35 to lift first the sleeve member I3 and the gripping jaws independently of the pilot 22 when the bottle is to be released for transference by the take-out devices.
Bottle take out The bottle take out mechanism as shown includes a four armed frame provided at the end of each of its arms with a shovel-like blade, said four armed frame being journaled to be intermittently rotated andswung to project the shovellike blades in succession under the elevated bottles to receive, support and transfer them to a belt for carrying them away, as to a lehr.
Referring more particularly to Figs. l, 2, 6, 1, 8, and 9 the character 4D designates the shovel-like blade of the fourarmed frame, said frame having a central shaft 4I journaled in a block 42 sliding in a groove 43 formed on or in a piece secured to a bed or plate 44 secured to the upper end of a stationary post 45. The shaft 4I is engaged by the free end of a horizontal arm 4BV pivoted at 41 and said arm is swung outward by a cam 48 on the vertically driven shaft 21 before referred to and said arm is swung inward by a spring 49 connecting the arm and shaft housing.
The shaft 4I carrying the shovel-like blades has secured to rotate with it a disk 50, said disk having four equally spaced downwardly projecting studs 5I with rollers on them, and pivoted at 52 on the bed or plate 44 is an L-shaped dog 53 having an inclined end 53a at its lower leg, and a cutaway portion 53b at the juncture of the legs. rI'he outer portion of the dog is made heavier than the inner portion so that in normal position the dog lies horizontally as shown by full lines Fig. 8, the inner end being intermittently depressed by the passage of the pins 5I over it when the arm 46 is swung inward. 'I'he stop 55 limits the position of the dog to horizontal position when the pressure of a pin 5I is removed. 5
The inward stroke of said arm 46, due to the draft of the spring 49, carries one of the shovels 4I) to position under the elevated bottle to receive that article when released by the grippers. The outward stroke of said arm 46 causes a quarter 10 rotation of the shovel wheel because on that stroke the pin 5I that has been carried over the top of the dog on the next preceding inward stroke is now arrested in the cut-away portion of the dog while the block 42 is carried to the 15 terminus of the outward stroke. In this opera.- tion it will be observed that the cut away portion of the dog forms a fulcrum for the arrested pin and permits the rotation of lthe rest of the wheel and its pins 5I by block 42 and arm 46 20 thereby causing in the mechanism, as embodied, a quarter rotation of the pin, disk and shovel wheel. In this operation the pin that is next to operate the dog is advanced in front of the inclined end of the, inner leg of the dog as shown 25 in Fig. '7. `To overcome any lag in the final movement of the wheel to the position described and shown there is provided a kicker 56 pivoted at 51 and pressed by an adjustable coil spring 56, against the inclined wall 56il on which the approaching pin slides thereby. compressing `the spring 58 and causing the kicker to impart an impulse to the Wheel supplementing the lever acl tion of the arm 46 to establish a quarter turn on the disk and placing the next advanced pin 35 5I inposition to go over the top of the inclineof the dog leg and into the recess of the dog beyond; or briefly again to the position shown in Fig. 8. In some instances the kicker may be dispensed with.
60 designates a belt for conveying the bottles away as to a lehr. 6I designates a stationary curved rail carried by the arm 46 to confine the bottles to the shovels in transit from the point of take-out to the belt 60. The character 62 des- 15 ignates a stationary finger connected with the stationary plate 44, said finger bent upwardly into position to contact with the side of the bottle to hold the bottle for deposit on the carrier belt 60 while the shovel draws away from it as the 50 shovel-carrying frame is swung toward a mold to take another bottle. i
Guard members 4I*i on the shaft 4I can be provided to assist in retaining the bottles on the shovels between the bottle taking operations of the shovel frame.
The travel of the molds, the oscillation of the arm 46 and the operation of the bottle lifting device 'are synchronized or timed to cause and permit the shovels in succession. to take a bottle in an interval between the movements of the molds.
From the above it will be apparent that as the mold 'with the ware in it, arrives at the takeout station, the mold is opened and the ware is 65 steadied by means of the plug 22 operated synchronously with the machine. Immediately the ware is elevated by the grippcrs II) and simultaneously therewith the frame 46 is moved toward the ware, positioning one of the supporting members 40 under the ware so that it may be supported solely thereby. As the frame 46 moves away from the mold, the carrier for the supports 40 is indexed, so that an empty support is available for the next bottle. Hence, the take-out is much faster than such mechanism heretofore used, which necessitates either a plurality of grippers or requires complete travel from the mold to the conveyor for each operation.`
The forms, proportions and numbers ofthe parts can be changed without departing from the gist of the invention as claimed.
