INVENTOR. Zia/V420 N /H L. M GIHON CASING MACHINE 2 Sheets-Sheet 2 Filed*- July 6, 1954 $11k AM 'The present invention elates to easing ma'chines of the ease inverting type and is "chiicerned *rho're particu- -larly with an improved machine or this charat'er which facilitates a smooth case handling "operation "during "the inversion thereof, and particularly during the discharge 'or an inverted ease, r p

In casing machines of the character disclosed in the co'pe'nding application of Anthony R. Silva, Serial No.

290,864, filed May 31,1952, now-Parent n 2,786,316, anarr'a of bottles is ftirhid'df *therequired number to ire ease, these bottles being fed in as'ries of parallel "files, and the *c'ase i's -placd thereove'r in invertedfcondition. Subsequently the bottlesf'with the case thereon are i5icked from 'th'eir split sup'port'sfb'y a parallel series of lift Farms and the case is inverted and deposited on a discharge conveyer, the eeav'e' er in this type 'of machine b'eing normally placed-at a low'er leyel than the position "of the bottle array.

In accordance with the instant invention, *a cohv'eyerof 'aspIitt'ype is provided to re'ceive the ease as it is leaving the lift arms after being inverted, and provides for a general rolling depositing of ureease 'onto the conveyer for discharge. The conveyer is preferably of a split type so as to permitpa's'sage bf the lift arms after discharge of a case for subsequent positioning in readiness to lift another array of bottles and case theie'on from'the casing station. e

. The above and other objects of the invention are at- "tai'ned as described in connection with a preferred e'mbodirrient thereof, as illustrated in the accompanying drawings, in which: I o

Reierri'ng to the arse/tags, thei'e 'i's showii a casihg mechanism including a feedconveyer for a series of parallel tfiles of bottles 11, this conveyer 10 feeding the bottles to a suitable casing mechanism 12 where the bottles areformed into a suitable case array forexample 24 bottles to the case, for placing of thecase 13 thereover in inverted position. The casing station 12 is constructed as disclosed in the copendin'g application of Leonard McGihon, Serial No. 328,889, filed December 31, 1952, and entitled Bottle Spreader, now Patent No. 2,755,611, and reference is made to said application for details of construction not disclosed herein. In general the casing station includes a series of pairs of split rails 16 (Figure 3) providing an opening 17 therebetween through which an associated lift arm 18 may pass to engage a row of bottle and lift them with the case thereon.v The lift arms 18 as seen in Figure 1 are formed in pairs and spaced 180 apart, being secured on a drive and support shaft 19in a conventional manner, and having attached thereto a case supporting member 21 of suitable structure to engage the end of the case during the case t d S at s. P e e fiatented May 2, 1961 inverting dperatioi'l. The shaft 19"is driven in a disclosed in said Silva application by a chain 22 from a. transmission including a E :yclica lly operable clutch providing-one halfrot ation of the shaft 19 "forea'ch were 5 "thereof. The =ti'ans missi6n '23 also provides "a'suit'able drive through the chain 24 mm reedeen'veyer '10.

From the roller conveyer 3'1 the c'a'se istransferred to a belt type dischahie conveyer '46 of conventional construction. w U 40 "From the above description it wil be seen that the casing machine notfqiily inv lves fa split types'upport for the bottlesfat the casingstation, but also providesfa split type discharge fsupport or conveyer, which extends inwardly into intersecting relatioifi'vith the pathof movement'of the lift arrhs 18 g k mg a'fter a easeisdischarged therefrom, -tlieroller c "er's ,1 being suitably "spaced so, as to permit the lift rms 18 tjo pass freely e rollers 31a to en age *s'iraultaiieeusiy the higher 'rollers 31b at position 13c. On further tilting'movement as shown at the position of the case 13b in Figure 1 the case will be pivoting about the roller 31b and then engage the subsequent series ,of rollers 31 (see 130) which are parallel therewith in a downwardly descending path so that a smooth discharge of the case is provided onto the discharge conveyer 46. This convex arrangement or configuration of the receiving end of the discharge roller type conveyers 31 provides a very smooth and easy discharge operation of the cases without undesirable jar accompanying the pivoting movement of the case. In effeet a case is allowed to roll down to its position as shown in 13c in Figure 1 rather than to drop abruptly to this position. It will be further noted that the elevation of the roller conveyer 31 is such as to be engaged by the case 18 while it is still supported on the case support bars 21. The arrangement delivers a case to a slight higher discharge position than its lift position on the casing unit 12. a
