1o claims. (ci. 22e- 14) The vpresent invention relates to vial processing machines and more particularly to a mechanism forV re? moving vials for processing elements, for orienting the vials into positions for loading, and for leading them into suitable trays.

In its more specilc aspects the invention concerns apparatus useful in removing vials from the jets of a washing machine in horizontal position then standing them upright and thereafter loading them into trays, all*l able tray loading apparatus by the aid of Which any size vial, within the range for which the main ymachine has been designed to handle, may be automatically removed from the washing jets, orientedto an upstanding posi? tion `and loaded into a suitable tray. j

The invention furtherproposes an improved structure and means for accomplishing the foregoing` ends ina manner requiring a minimum of parts and mechanism.

subject to possiblederangement by an inattentive or unskilled operator. invention proposes an improved tray loading mechanism operative automatically to bring the main machine 'as well as lthe loading mechanism to a stand still in the event", the operator fails to remove a fully loaded tray from the' p machine or, if and when removed, the operator fails to place an empty tray in proper receiving position on the machine.

For the purpose of explaining the nature ofthis invention reference will be'made to washing machines of the general style and character of those illustrated in 'the patents to Cozzoli #2,604,896 and `2,555,875 which include essentially, an indexible endless conveyor provided with a plurality of banks of processing jets upon which the containers to be washed are initially placed and carried successively to and through a number of processing stations. The jets are loaded at one end of the machine and upon each operating cycle a bank of jets with vials telescoped thereon vare presented at a delivery station. stroke rake element adapted to engage the vials at the delivery station and to Withdraw the vials from the jets and move them a distance not only suiificient to permit the empty jets to pass and a new lot to move into position but to move them along guided channels to an orienting station where they are caused to taker an upright posi- As an additional safety measure the The present invention comprehends a variable and eject the faulty vial. vfor separating'vials that may tend to stick together and tion. Thereafter, and in timed cycles, the vials are taken from the'orienting station and channeled into the open end of a receiving tray placed at the end of the channel. Means are provided by which the main machine is stopped when a lled tray is removed from the machine or when a filled tray is not removed and the loading mechanism attempts to force more than the trays complementy of vials into the tray. In addition the invention proposes a means lfor adjusting the stroke of the rake member so that relatively long or relatively short vials may arrive at the orienting station one group at a time, i. e., but one group of vials are presented to the orienting'station in each index cycle of the main machine, and similarly but one group of vials are taken from the orienting station in each index cycle of the machine. These operations of withdrawing, orienting, and channeling of successive groups of vials are effected automatically and in timed sequence as will be explained.

By way of additional refinement the invention undertakes to provide safety means operative to protect the machine from injury in the event a vial is misplaced and/or improperly comes through the processing machine. In such a case thereceiving platform may yield Similarly means are provided additional means to prevent them from adhering to movable parts.` By the aid yof such safety measures the machine is rendered self-clearing and non-jamming.

Other objects and advantages will be in part indicated 4in the following description and in part rendered apparent" therefrom inconnection with thev annexed drawings.

Depending upon the length 'of the vials being processed the stroke of the vial rake is adjusted so that but one bank of vials is pushed off and self-oriented on the shelf 50 on each operating cycle, and the bank of vials next following are brought torest at the brink of the extension.

Underlying the channeled vextension 18C is a vial'pusher carriage 51 reciprocably mounted 'on rollers 52 that are guided in channelsSS at lcach side of themachine frame. The forward face of the carriage 51 is provided with a series of pockets 50a, spacedfrom one "another in correspondence with-the spacing of the Vfchannels in the receiving plate 18 and its extension 18C. Normally the pockets 50a occupy a position partly under the brink of the extension 18e so that as the vials drop off the latter they f all into the pockets and are. guided1= and maintained .upright therein.

At the end of the carriage forward stroke the gate lowers a given amount and then the carriage recedes in preparation to receive, f

another charge of vials. the vials that were left standing unconined on the platform 5 0 are engaged by the oncoming group ,of vials and advanced still further along the platform.

The preliminary portion of the descent of the gate 60 is utilized in'this embodiment of the invention afrmatively to eject the vials from their pockets in the pusher so that they will not stick to the pockets and be carried backward. To this end the gate is provided with a cross-bar 60e that carries a series of downwardly projecting pinsor needles 60d. After the vials have passed under the needles 60d the needles lower and enter recesses 50c provided in the carriage immediately behind each vial pocket. When in their partially down position the needles prevent the vials from adhering to their pockets and from being carried back with the carriage 51. After the carriage has receded beyond the gate 60the latterlowers the remaining amount and is positioned in receiving relation with the withdrawn carriage for the next bank of vials. The two-stage lowering of the gate 60 and needle bar 60C is controlled and timed by providing cam 71 with the stepped descending portions indicated at 71a, 71h and 71e.

In accordance with this invention, the vials are caused to be channeled automatically into the open end of one or more receiving trays. v in the drawings a single tray 85 is positioned to receive the vials. This tray is closed on three sides and its bottom is arranged to underlie the platform 50. The platform 50 is preferably relatively thin particularly the portion that overlies the tray bottom so that the vials do not tip over as they are advanced from one tothe other. Side guides 86 adjustably secured` to the platform 50 are provided to'channel the vials tothe width of th'open end of the tray.

The support for the tray S5 may comprise a separate stand yor frame, or a frame that may be secured to the main apparatus as indicated in the drawings. As shown herein the tray support includes a top 87, an under frame 88, yand one or more legs 89. The inner end of the under frame 88 is preferably secured to the main frame extensions 64 ywhereby the relative elevations of the top ,87 and the platform 50 may be maintained at'the spaced distance required to slide the bottom of the tray 85 between the two. To accommodate the sides 85a of the tray On the next following stroke ln the example represented will thereupon advance in an elevated position and grad- 46 A preferred formof mechanismfor this purposeincludes a control switch 100 velectrically connected .with

the starter switch ofthe motor that drives` the power shaft 15 A control circuit diagram is illustrated schematically in Figure 6. The tray switch `100 is providedwith a yieldable roller 101 that .is positioned to'engage the leading end of the tray and which when depressed by a tray inserted between platform 50 and stand top 85, closes a portion of the circuit to the main drive motor. When this switch 100is closed, the motor'may be operated to drlve the shaft 15. If a tray is not present, or if pres-v ent, is caused to shift rearwardly a predetermined amount,

the switch roller 101 lifts slightly and opens the circuit. inthe washing machine organization illustrated'in part herein,A the main drive motor M operates a cam 150 thatiactuates a cycle switch 161 connected across the starting circuit so thatfthemachine is caused to cease functioning at the completion of a washing cycle at which time the processing valveshave been actuated to closed position and the processing tluids shutoff.

It will also be seen thatvthe tray switch 100 operates 'i to stop the machine when a filled tray is removed and about to be replaced by an empty tray. During the interval required to change trays, the machine is at rest .and no vials are being radvanced along the platform 50.

P referably,'t`he platform 50 is caused to'overlap the lead-v ing end of a tray a'distance suicient to accommodate a full complement of yvials advanced by a'forward stroke of carriage 51, `so that when it is time to remove a lled :5otray adequate space remains in that covered portion of the tray to receive the vials that are vadvancing on that cycle and such other vials as may have been advanced partly voff the platform 50 at the time the machine' cyclel stops.

' A y Operation The operation of the. vial removing and loading mechanism is as follows: Assuming that the jets of theywashing machine have been supplied with vials, a first bankk of vials will arrive at the delivery station andlie -hori' zontally in the channels of the'platform 18. The rake 20 ually4 descend upon the necks ofthe vials. When fully seated the crank pin will have passed dead center 85 (and a partition 85b if the tray is so made) they platform 50 is provided with suitable slots 50s which also serve yas guide means for registering the tray with the channel guides 86. To prevent the tray from inadvertently receding as the vials are advanced a back stop 90 is provided on the top 87. The back stop in thisj in,

stance comprises an angled strip, shallow enough to alV low the tray to ride over but steep enough to offer sucient resistance to hold the tray in place against the urge of the incoming vials. Should, however, the tray become filled and is left unattended, the pressure of the and through the connecting rod 44, vlever 40, link 42 and carriage 21 will move outwardly and draw the vials off the jets. This operation repeats itself until the, extension platform 18a is filled with rows of abutting vials and on the next cycle the vialsatthe brink of the platform are pushed off the platform 18a and fall right end ,upv upon `the lower platform 50. At this pointin the operational cycle,.the pusher carriage 51 is in its In position, the

gate 60 is down and the vials are confined in orderly arrangement by the pockets 51a and the face ofthe gate.v

60. Thereafter the gate elevates in responseto the action of cam 71 to a position whereat lthe vials may pass beneath. At this time the pushercarriage 5,1 advances in response to its cam 80, and the partially confined vials are moved along the-platform 50. When the carriage cam reaches; its maximum throw position with relation to thefollower 79, forward movement ofthe vials ceases, the gate lowers a preliminary amount 'to eject the vials,

and the carriage is retracted by the force of pull springs 74a connected to lever 74,and a stationary part of the machine. When the carriage has cleared the gate and is retracting, the gate, completes its down movement by gravity assisted by the force of pull springs 67a connected with lever 67, under the control of the cam 71. As the gate arrives in its down position another bank of vials is about to be orientedby falling into the pockets 51a fand on the ensuing cycle of the gate and pusher carriage V,

another bank of vials are advanced along the platform and brought into engagement with the previous bank of free-standing vials.

The latter are accordingly advanced lstill further and'in doing so assume a varied pattern. As the machine-continues to cycle in this manner, successive banks .of vials fare'=nnloa'c`iedfrom "'the jets, 'oriented and advancedalong' the :platform 50 land "'iin'd their way in mixed fashion betweenthej side 'guides 86,*tof't'he open-end of`the'tray^85. vWherithe'tray has lbeen tilled, the operatorreplaces thefilled. traywith Ian empty one, the machine being-'automatically stopped during the interval the leadin'gjend cfa tray remains off the 'switch 'actuating roller`101.
