Title: Improvements relating to automatic machines for mixing different products in specifled proportions
IPC: G01G19/22
Filed: 1929-04-22
Abstract: 316,862. Soc. des Sucreries Ternynck. Aug. 3, 1928, [Convention date]. Automatic-feed weighers.-Apparatus for automatically feeding liquids, solids, or solids and liquids, in definite proportions to a mixing machine comprises means for feeding the materials to tipping scale pans, means being provided for controlling from a single pan the operation of the feed to the other pans, and for stopping the feed to that pan in the event of the failure of the feed to any of the others; means are also provided for stopping the apparatus when the output vessel to which the pans discharge is filled. In the form shown, a solid is fed with a liquid, the solid being fed by a rotating pocket wheel 1 operated from a main shaft through a disconnectible coupling 10. The pocket wheel discharges into a pan 2 pivoted at 32 and balanced on a beam 30 by an adjustable weight P1. The pan is weighted at 31 and when empty assumes the position shown with a projection 40 under a retaining catch 6. When the pan is full it falls and the beam 30 engages a weighted lever 8 to release a second weighted lever 9. The lever 9 at one end is connected by a link 75 with a pivoted arm 77 the free end of which engages a member 27 to disengage the coupling 10 and thus stop the pocket wheel. The other end of the lever 9 is connected by a link 37 to the catch 6, the release of which allows the pan to discharge. A third arm 65 of the lever 9 is connected by linkage 66<1>, 66<2>, 66<3> with a catch 12 the operation of which frees the pan 4 for the liquid ingredient and allows it to assume its filling position. The pan 4 is supported on a beam 50 and is supplied from a tank 42 the discharge of which is controlled by a weighted lever 43 and cock 3. The cock is opened from the pan 2, an arm 60 engaging a pin 63 on an arm 16 integral with the lever 43, the arm being connected by a link 15 with an arm 11 which is engaged on the return move-- ment of the pan 2 by a roller 5 thereon; operation. of the arm 11 also resets the lever 9. The cock 3 is shut off when the pan 4 is full by the engagement of the beam 50 with a weighted lever 14 having a notched end 61 engaged by the arm 16. Should the cock not be closed owing to the pan 4 not falling due to failure of the liquid supply, an arm 82 of the lever 43, through interconnections 83<1>, 83<2>, operates a stop 7 which then engages a projection 85 on the arm 9 and prevents its operation, thus stopping the feed to the pan 2. When more than two ingredients are mixed, each of the other pans is provided with similar mechanism controlled by, and controlling, the pan 2 and its associated feed. To stop the mechanism when the discharge tank is full, the latter is provided' with a float which operates a member similar to the member 7. For feeding two solids, the feed' mechanism 1 and its stop mechanism is dupli-- cated; similarly when liquids are to be mixed the tank-controlling linkages shown are used.
