Abstract

A transmitter for use in the food industry for unique identification of a transport device such as a hanger for a carcass or a container for food products is mounted within a housing which protects the transmitter from heat, water, corrosive materials and shock loads. The housing comprises a cylindrical ring having one end welded to a suitable support element on the hanger and a second open end. The transmitter itself is in the form of a flat disc molded within a generally cylindrical body which can be inserted into the ring. A male thread is formed on the outside of the cylindrical body and a female thread of the inside of the ring allowing the device to be readily attached into the ring. The body is molded from silicone rubber which provides the necessary protections while allowing the communication of signals to and from the transmitter through the open face of the ring.

Claims

1. An electronic tagging apparatus comprising:

an electronic transmitter for transmitting an electronic code signal providing an identification code substantially unique to the transmitter;

and a housing arranged for mounting the transmitter on an object to be tagged and arranged such that the housing encloses the transmitter and protects the transmitter from heat, water, corrosive materials and trauma, the housing comprising;

a substantially rigid mounting member for attachment to the object;

a body enclosing the transmitter;

and means mounting the body on the mounting member;

the body being formed by molding from an elastomeric material with the transmitter embedded within the material during molding so as to be fully encapsulated by the elastomeric material and so that all outer surfaces of the body are maintained at a spaced position from the transmitter determined by a thickness of the molded elastomeric material therebetween;

the molded elastomeric material being stiff so that all outer surfaces of the molded body are supported at said spaced position from the transmitter by a stiffness of the elastomeric material.

2. The apparatus according to claim 1 wherein the body is molded from silicone rubber.

3. The apparatus according to claim 1 wherein the mounting member comprises a rigid structure formed from a rigid material separate from and different from the elastomeric material and wherein the rigid structure is arranged for rigid attachment to the object.

4. The apparatus according to claim 3 wherein the mounting member is shaped to define a recess having rigid sides at least partly surrounding the recess and wherein at least part of the outer surfaces of the body are arranged to engage at least part of the sides of the recess to hold the body and the transmitter within the recess with the transmitter spaced from the sides of the recess by the thickness of the body.

5. The apparatus according to claim 4 wherein recess of the mounting member has an open front face and wherein the body includes an insert portion which is shaped to engage into the recess and includes an end portion which defines a front surface covering the open front face.

6. The apparatus according to claim 5 wherein the insert portion of the body includes connecting means molded thereon for releasably and readily reengageably connecting with the mounting member.

7. The apparatus according to claim 5 wherein the sides of the recess of the mounting member form an annular ring and wherein the insert portion has a cylindrical outer surface for engaging into the ring.

8. The apparatus according to claim 7 wherein the insert portion carries a male thread on the cylindrical outer surface and wherein the ring has a female thread on an inside surface thereof.

9. The apparatus according to claim 5 wherein the end portion is of larger transverse dimension than the open front face to define a shoulder surrounding the open front face.

10. Apparatus for tracking a plurality of product elements during transportation thereof comprising:

a plurality of transport devices for moving the product elements through a series of processing stations, each transport device being arranged to receive a respective one of the plurality of product elements;

each transport device having mounted thereon the electronic tagging apparatus according to claim 1.

11. An electronic tagging apparatus comprising:

an electronic transmitter for transmitting an electronic code signal providing an identification code substantially unique to the transmitter;

and a housing arranged for mounting the transmitter on an object to be tagged and arranged such that the housing encloses the transmitter and protects the transmitter from heat, water, corrosive materials and trauma, the housing comprising;

a body enclosing the transmitter the body being formed by molding from an elastomeric material with the transmitter embedded within the material during molding so as to be fully encapsulated by the elastomeric material and so that all outer surfaces of the body are spaced from the transmitter by a thickness of the molded elastomeric material;

a substantially rigid mounting member comprising a rigid structure formed from a rigid material separate from and different from the elastomeric material and wherein the rigid structure is arranged for rigid attachment to the object;

and means mounting the body on the mounting member;

the mounting member being shaped to define a recess having rigid sides at least partly surrounding the recess and wherein at least part of the outer surfaces of the body are arranged to engage at least part of the sides of the recess to hold the body and the transmitter within the recess with the transmitter spaced from the sides of the recess by the thickness of the body.

12. The apparatus according to claim 11 wherein the recess of the mounting member has an open front face and wherein the body includes an insert portion which is shaped to engage into the recess and includes an end portion which defines a front surface covering the open front face.

13. The apparatus according to claim 12 wherein the insert portion of the body includes connecting means molded thereon for releasably and readily reengageably connecting with the mounting member.

14. Apparatus for tracking a plurality of product elements during transportation thereof comprising:

a plurality of transport devices for moving the product elements through a series of processing stations, each transport device being arranged to receive a respective one of the plurality of product elements;

each transport device having mounted thereon the electronic tagging device according to claim 11.

15. An electronic tagging apparatus comprising:

an electronic transmitter for transmitting an electronic code signal providing an identification code substantially unique to the transmitter;

and a housing arranged for mounting the transmitter on an object to be tagged and arranged such that the housing encloses the transmitter and protects the transmitter from heat, water, corrosive materials and trauma, the housing comprising;

a body enclosing the transmitter the body being formed by molding from an elastomeric material with the transmitter embedded within the material during molding so as to be fully encapsulated by the elastomeric material and so that all outer surfaces of the body are spaced from the transmitter by a thickness of the molded elastomeric material;
