1,067,485. Conveying systems. BALL BROS. CO. Inc. June 18, 1964 [Aug. 5, 1963], No. 25235/64. Heading B8A. Apparatus for conveying cartons beneath an article inspection conveyer 11, comprises a free roller conveyer 40, mounted for vertical and transverse movement and rotation about the longitudinal axis. The vertical movement of the conveyer 40 is accomplished by a scissors jack arrangement comprising pairs of pivoted links 49 coupling an upper and lower channel 48, 47 and operable by a rotatable screw 45 engaging nuts 46 pivoted to the links 49. The transverse movement of conveyer 40 is effected by rotating screws 50 rotatably mounted thereon, in threaded bushings 51 which are pivotally connected to the channel 48. For rotary movement of the conveyer 40, a sleeve 54 pivoted to the channel 48 rotatably mounts a screw 53 which engages a threaded aperture 55 in a member 56 secured to the bushings 51. Wheels 57 mounted along one edge of the conveyer 40 retain cartons thereon in the inclined attitude. Cartons carried by endless belts 30, 31, 38 and rotating disc 32 are guided thereon by rails 33, 34 the latter being adjustable. Plates 36, 37 support the cartons between the belts and the disc and ball joint ended telescopic rods 41 span the area between the belt 38 and the adjustably positional conveyer 40. The cartons are pushed along the latter and over the plates 36, 37 by the following cartons. The article inspection conveyer comprises an endless belt 11 along which articles travel for inspection and adjacent parallel endless belts 23, 25, 26, 24 which move in the opposite direction and on to which reject articles are placed. A rail 19 deflects the reject articles across the belts 23, 25, 26 on to belt 24. Accepted articles are picked from the belt 11 by the inspector and placed in a carton on the conveyer system thereunder whence the filled carton is conveyed away for shipping. An accumulator at the discharge end of the conveyer 11 stores articles which have not been inspected, ready for later inspection. The accumulator comprises a rotating disc 27 having a peripheral guide rail 28 with a readily adjusted end section 35 (see Fig. 14, not shown). An extension 29 of the rail 28 deflects the articles from the conveyer 11 on to the disc 27. The control of movement from the conveyer 40 may be controlled electrically. The carton conveying system may be operated intermittently. |
