Abstract

789,575. Weighing apparatus. S.A.S.I.B., SOC. PER AZIONI SCIPIONE INNOCENTI-BOLOGNA. April 12, 1956 [April 13. 1955], No. 11226/56. Class 143 An apparatus for recording the weights of batches of cigarettes extracted at intervals from a cigarette making machine (not shown), marks a chart 56 (Fig. 13), with lines C which are arranged in columns, each corresponding with a batch weight falling within a predetermined range, the length of each line indicating the number of batches failing within the associated range. A cam mechanism (Figs. 3 and 9, not shown), driven in timed relation with the machine, causes a bar 80 (Figs. 7 and 8). to press an arm 13. pivoted about an axis 15 on the weigh beam 3. against one of a series of lugs 77 carried by arms 72 pivoted about a' common axis 73. The consequent movement of the engaged arm steps the associated ratchet wheel 67 which. through gearing 66. 65. 63. 60 moves the associated marker 50 upwardly over chart 56. At the same time bar 80 steps a further ratchet wheel 171 (Fig. 8) which. through similar gearing, moves a further marker to produce a line N (Fig. 13), the length of which indicates the total number of weighings. The markers 50 are provided with indicating pointers 53 which project through vertical slots in a stationary calibrated plate 55. The cam mechanism is arranged to move the chart horizontally after a predetermined number of weighings to produce horizontal interruptions in in the lines C and N which, when joined by dotted lines as shown in Fig. 13. produce a set of distribution curves of the weights of the batches produced by the machine The gearing chain 60 driven by the ratchet wheel 171 carries a projection 106 which engages a switch operating arm 107 when the associated marker is at the top of the chart and thereby renders the apparatus inoperative until it is reset. The weigh pan 8 (Fig. 11), which is supported from the weigh beam 3 by a rod 10 is provided with a pivoted base member 27 which is moved to the dotted line position to discharge the weighed batch by a spring loaded lever 29 movable by a rod 32 which is reciprocated by the cam mechanism and which also serves to lock the beam in its container 1 and a reciprocating piston 7. is contained in a case provided with locking mechanism which when unlocked automatically frees the wheels 67, 171 and allows the markers to be reset. Beam 3 is also provided with a weight indicating pointer 11 and a damper 18, 19. In a modification (not shown). levers 72 operate micro switches-which control the operation of the cigarette making machine. In a further modification (also not shown), the markers are controlled by electric devices which are energized by switches operated by either the pointer 13 or the arms 72.
