Abstract
A machine which has an endless conveyer belt for conveying workpieces past a work station where operations such as, for example, grinding operations are performed on the workpieces. Thus this conveyer belt has upper and lower runs and a support extends between these upper and lower runs and has an upper surface engaging a lower surface of the upper run of the conveyor belt to support this upper run for sliding movement. A part of the upper surface of the support, which engages the lower surface of the upper run of the belt, includes structure for cleaning the conveyor belt at the lower surface of its upper run so as to avoid any possible undesired separation of the upper run of the endless belt from the upper surface of the support.
Claims9
In a machine which includes an endless conveyer belt having upper and lower runs, and a support extending between said upper and lower runs and having an upper surface engaging a lower surface of said upper run to support the latter for sliding movement along said upper surface of said support, and means situated at said upper surface of said support for cleaning the lower surface of said upper run of said belt and for preventing undesired separation of said lower surface of said upper run from said upper surface of said support, the machine being a grinding machine and including a rotary grinding wheel situated over said upper run of said belt for grinding workpieces conveyed by said belt past said grinding wheel between said upper run of said belt and said grinding wheel, said grinding wheel having a lower tapered grinding surface of circular configuration provided with inner and outer peripheries and situated with its inner periphery closer to said belt than at its outer periphery, said surface of said support which engages said lower surface of said upper run of said belt and said upper run of said belt therewith being inclined at least slightly with respect to the axis of the grinding wheel, at an angle other than a right angle, for conveying the workpieces downwardly with respect to the grinding wheel so that when the grinding is completed at one side of the inner periphery of the grinding wheel the workpieces will clear the grinding wheel at an opposite side of the inner periphery thereof.
