Abstract

An assembly for processing bead-apexes includes a weighing device for measuring the weight of one of the bead-apexes and at least one station for supplying or receiving the bead-apexes to or from the weighing device in a supply direction or a discharge direction, respectively. The assembly further includes a frame for supporting the at least one station, wherein the weighing device has a weighing member for receiving and supporting one of the bead-apexes and a base member connected to and forming a base for the weighing member. The weighing device is arranged for measuring the weight of the one bead-apex on the weighing member, while the weighing member is arranged for keeping the one bead-apex stationary during the weighing, while the frame of the assembly and the base member of the weighing device are supported independently.

Claims26

Dependent claims

An assembly for processing bead-apexes, wherein the assembly comprises a weighing device for measuring the weight of one of the bead-apexes, a supply station at a supply position for supplying the bead-apexes to the weighing device in a supply direction, and two or more follow-up stations at two or more follow-up positions for receiving the one bead-apex from the weighing device wherein the assembly further comprises a frame for supporting the supply station, wherein the weighing device comprises a weighing member with a weighing surface for receiving and supporting one of the bead-apexes in a horizontal weighing plane and a base member connected to and forming a base for the weighing member, wherein the weighing device is arranged for measuring the weight of the one bead-apex in a weighing position on the weighing member, wherein the supply station defines a supply plane parallel to the weighing plane, wherein the weighing plane is arranged to be in line with the supply plane when supplying the one bead-apex to the weighing device, wherein the weighing member is arranged for keeping the one bead-apex stationary during the weighing, wherein the assembly further comprises a control unit which is operationally connected to the weighing member for receiving a signal indicative of the measured weight of the one bead-apex, wherein the control unit is arranged for selectively controlling the movement of the one bead-apex to one of the two or more follow-up stations based on the weight of the one bead-apex, and wherein the weighing member is movable relative to the base member in an alignment direction from a first transfer position in alignment with the supply position into a second or further transfer positions in alignment with any one of the two or more follow-up positions.

An assembly for processing a bead-apex, wherein the bead-apex comprises a circular bead and a filler apex extending radially outward from said bead, wherein the bead has an inner rim extending in a bead-apex plane and forming a circular opening, wherein the assembly comprises a weighing device for measuring the weight of one of the bead-apex and a follow-up station at a follow-up position for receiving the bead-apex from the weighing device, wherein the weighing device comprises a weighing member with a weighing surface for receiving and supporting the bead-apex in a horizontal weighing plane and a base member connected to and forming a base for the weighing member, wherein the weighing device is arranged for measuring the weight of the bead-apex in a weighing position on the weighing member, wherein the weighing member is arranged for keeping the bead-apex stationary during the weighing,

wherein the weighing member has a circumferential edge facing one of the one or more follow-up stations, wherein the weighing surface is arranged for receiving and supporting the bead-apex in the weighing position such that a part of the bead-apex protrudes from the weighing surface towards the follow-up station and a part of the circular opening of the bead-apex is extending beyond the edge of the weighing member, wherein the rim of the bead at the part of the circular opening that extends beyond the edge and the edge of the weighing member are facing each other at a gap distance, wherein the follow-up station is arranged for engaging the protruding part of the bead-apex from its respective position, wherein the weighing member is movable relative to the base member in an alignment direction transverse, perpendicular to the weighing plane into a respective transfer position in alignment with any one of the one or more follow-up positions, and wherein the weighing member and the follow-up station are arranged for causing the bead-apex to pivot around the rim of the bead when the weighing member and the follow-up station are moved relative to each other in the alignment direction and the rim of the bead is supported on the follow-up station.
