1,034,290. Endless conveyers. BAKER PERKINS Ltd. Nov. 12, 1964 [Nov. 12, 1963], No. 46107/64. Heading B8A. An endless belt conveyer 10 receives pansets p of proofed dough from a proofer P, transfers them to a conveyer 11 which in turn transfers them to a conveyer 12 which transfers them to an oven supply conveyer 13. The conveyers 11-13 each employ a pair of spaced apart runs. Each of the conveyers 10-13 is driven by a separate electric motor. Limit switches LS-1, LS-3, LS-2 are respectively located at the delivery end of the conveyers 11, 12, 13. The conveyer 11 is driven faster than the conveyer 10 to spread the pansets p out to facilitate lidding at an adjacent lidding station. Arrival of the leading pansets p at the limitswitch LS-1 stops the conveyer 11 for a preset time delay to permit lidding while stopping the conveyer 10 at the same time. The pansets p pass on to the conveyer 12, which is considerably slower than the conveyer 11, and on reaching limit switch LS-3 actuate it. As long as the limit switch LS-2 on the conveyer 13 is not actuated, actuation of the limit switch LS-3 is without effect, but actuation of the limit switch LS-2 when the limit switch LS-3 is actuated causes the conveyer 12 to be stopped while the pansets p on the conveyer 13 are fed to an oven O. The conveyer 13 is driven faster than the conveyer 12 to spread the pansets p to achieve proper colour uniformity in baking. If the oven O runs so slowly that groups of pansets p back up on to the conveyer 10, which is stopped, a photo-electric system 16a, 16b, 16c halts the proofer unloader until the pansets p on the conveyer 10 move off on to the conveyer 11. An electrical control circuit is given in Fig. 2 (not shown). |
