Patented June 7, 1932 UNITED STATES HARRY D. LATHROP, CHICAGO, ILLINOIS CAN DUMPING MECHANISM Application filed Apri1 19, 1980 Serial No. 445,813.
This invention relates to can dumping mechanism, especially designed for the mechanical engagement and manipulation of filled cans, or other receptacles of a like nature, to dump the contents thereof. An object of the invention is the provision of improved mechanism capable of engaging a receptacle such as a milk can or cream can deposited on areceiving platform, and translu porting the samethrough an arcuate path, in
which process the position of the can is inverted and the contents gradually discharged or dumped into a vat or similar container, after which the can or receptacle is deposited upon a discharge platform. As an additional object, the invention provides mechanism of the character indicated which is durable and eflicient for the purpose, although comparatively simple in construction and operation, and relatively economical to manufac ture and maintain in operation. A more specific object resides in the provision ofmechanism for engaging, in a positive gripping action or manner, a milk or cream can in upright position, and rigidly maintaining a gripping engagement while the can or receptacle is transported through an arcuate path of substantially 180 degrees, during which travel the contents is discharged into a container and at the conclusion of which the can or receptacle is disengaged and deposited upon a discharge platform or conveyor.
Other objects will appear hereinafter.
The invention consistsin'the combinations and arrangements of parts hereinafter described and claimed. The invention will be best understood by reference to the accompanying drawings, forming a part of this specification, and in which:
Fig. 1 is a side elevational view of a typical apparatus, shown in operative association with a can washing machine;
Fig. 2 is a plan view of the machine as shown in Fig. 1;
Fig. 3 is a sectional view, taken substantially on the line 3--3 of Fig. 2, to illustrate one of the can gripping arms;
Fig. 4 is a horizontal sectional view, taken substantially on the line 4- 4 of Fig. 3; and
' Fig. 5 is a detail sectional view showing the relative positions of the receptacle and grlpping arms at the uppermost point of travel,
in which position the arms are disposed vertically and the can or receptacle horizontally.
As illustrated in the drawings, the preferred embodiment of the invention comprises a supporting framework having vertical standards '9 which may be'of channel iron or'similar construction, and four standards 10 adapt-ed to extend to a greater height than the standards 9. The respective standards are provided with leveling bolts 11 and are adapted to support adjacent the lower extremities a bed plate 12, upon which is mounteddriving motor 13 and reduction gearing assembly 14. Bed plate 12 is preferably secured to longitudinally extending angle irons 15, and an upper can receiving. platform 16 may be similarly secured to and supported by longitudinally extending angle'i-rons 17 It will be understood that in lieu of a stationary I can receiving platform 16, a gravity or power driven conveyor may be employed.
Keyed or pinned to shaft 32 are a pair of spaced arm supporting blocks 37 and 38 adapted to carry revolving can gripping arms 39 and 40, respectively, and inasmuch as the construction, arrangement and mounting of arms 39 and 40 are identical except that they are arranged in opposed relation to each other, a description of gripping arm 39 by reference to Figs. 3 and .4 will suflice. Block I 37, as shown in Fig. 4, has a projection 41 'arly inclined p0 upon which arm 39 is pivotally mounted by means of pin 42, but arm 39 is arranged to extend on the opposite side of shaft 32 from projection 41, and therefore the arm isprovided with an opening through which shaft 32 extends. A compression spring 43 dis. ggs'ed in recess 44 of block 37 is adapted to ar against the inner surface ofarm 39 to normally force the latter outwardly, or in the direction of a stationary vertically disposed cam member 45, against the inner circular surface of which roller 46 on arm 39 is adapted to contact.
As shown in Figs. 3 and 5, the cam member 45. has an upper inwardly extending cam portion 47 adapted to force arm 39 inwardy, as shown in Fig. 5. An inclined plane portion 48 is engaged by roller 46 on the a roach of arm 39 to cam surface 47, and simirtion 49 is engaged by roller '46 as arm39'1s carried beyond cam portion 47. Similarly, 'arm 40 operates in conjuncv tion with stationary cam member 50 on theopposite side of the machine having an upper cam 'surface'51 and incllned portion 52 engageable by roller 53. Thus, it will be seen that as shaft 32 rotates in a clockwise direc tion from the position shown in Fig. 1, arms 39 and 40 are revolved and as they approach a horizontal position from the lower half of the revolution, they are forced toward each other into gripping engagement with the oposite sides of a can 54 which has been rought to the position shown in Flgs. 1 and 2.
To afford a certain degree of resiliency in the gripping members and compensate for slight irregularities, each arm 39 and 40 carries a gripping shoe 55, the inner surface of which is curved to conform to the curvature of the milk can, and covered with leather, rubber or equivalent material. Each shoe 55 carries rearwardly extending bolts 56 which extend through openings in the arm and within coiled springs 57 normally adapted to force shoes 55 inwardly, the inwardmotion being limited by nuts 58. On the opposite side of shaft 32 from receiving platform 16 there is preferably arranged a discharge platform which, in the embodiment shown, is in,
the form of stationary curved rails 59 upon which the cans are adapted to he slid for engagement by a pawl 60 mounted on a reciprocating carriage associated with a canwashing machine 61. A milk or cream receiving vat or container 62 is arranged below the rails 59.
As shown in Fig. 1, can gripping arms when in horizontal position are disposed substantially midway between the upper and lower extremities of the can whereby when the can is inverted to complete a dumping operation, disengagement will occur at the diametrically opposite position when a can has been deposited upon the rails 59. For this purpose the cam surfaces or portions 47 and 51 extend substantially above a horizontal plane through the cam members 45 and 50 for a distance of approximately 180 degrees.
The principle. and mode of o eration has been indicated to some extent y the foregoing description, but in further explanation, a-filledmilk can is brought to the position shown in Fig. 2, and as arms 39 and 40 revolve. engagement is effected by the arms being forced toward each other through the medium ofthe cam surfaces described to cause gripping engagement and rigid maintenance in this engagement during a revolution of approximately 180 degrees, after which the cam surfaces providefor disengagement by the spreading actionof the arms. As the arms are disengaged on the discharge side they continue in their revolving travel to engage the next succeeding can'brought to position, and
as each can is deposited'upon the discharge rails 59 it may be moved. or shifted manually or mechanically, either to a'conveyor or for direct introduction into a can washing machine, asshown; While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of. variation andmodification without de arting from the spirit'of the invention. I, t erefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
