US 5,997,271 A · Device for managing molds used for mechanically producing molded objects of building material

Abstract

A device for managing mold operation for production of molded objects of building material, such as for example concrete, discourages tampering of data collected pertinent to use of a particular mold over time. Various relevant parameters of the manufacturing process are stored in a transponder during active use thereof on a building material machine, the transponder being non-detachably connected to the production mold. The transponder is fixed to the mold in a manner inhibiting tampering with data stored therein and shielding same from mechanically induced damage. The above arrangement of the device permits subsequent retrieval and utilization of the accumulated stored data with write/read equipment available only to authorized personnel.

Dependent claims

A device for supervising molds used for the mechanical production of molded objects of building material and which are received on a building material machine during a filling operation, comprising:

a transponder nondetachably connected with a structural portion of the mold, at least a portion of the transponder being received in a cavity formed in the structural portion;
a write/read head separate from the transponder, the write/read head including means for communicating with the transponder when brought within a minimum communication distance therefrom, disposed, at least during the transfer of data, at a component of the building material machine, the transponder and the write/read head being disposed at respective regions of the mold and the building material machine which are brought into overlaying contact engagement during the filling operation and positioned such that the transponder and the write/read head vertically oppose one another at a distance from one another less than the minimum communication distance during the filling operation;
and
the building machine including a shaking table on which the mold is supported for shaking thereof during the filling operation.

1 more element

A device for supervising molds used for the mechanical production of molded objects of building material which are received on a building material machine during a filling operation, the building machine including a shaking table on which a respective mold is received and shaken thereby after being filled with the building material to assist in consolidation of the building material in the respective mold, the device comprising:

a transponder nondetachably connected with a structural portion of the mold, at least a portion of the transponder being received in a cavity formed in the structural portion;
and
a write/read head separate from the transponder, the write/read head being communicative with the transponder when brought within a minimum communication distance therefrom, disposed, at least during the transfer of data, at a component of the building material machine, the respective mold and the building machine being free of structure encumbering at least a degree of horizontal deflection of the respective mold relative the building machine when shaken on the shaking table on which it is received, the transponder and the write/read head being disposed at respective regions of the mold and the building material machine which are brought into overlaying contact engagement during the filling operation and positioned such that the transponder and the write/read head vertically oppose one another at a distance from one another less than the minimum communication distance during the filling operation.
