Abstract

The present coding system is intended to be used in connection with a system containing several robot workstations along a line, where pallets are used for supplying materials and tools to the work stations. The coding system, consisting of code unit 1 and code-setting unit 2, is fixedly mounted onto the pallet 3 and comprises a profile 4, having a suitable number of coding elements 5. These coding elements are adjustable by code-setting element 2 into upper position 6 and lower position 7. When coding element 5 is in upper position 6, a reflex tape 8 is exposed, the tape being attached to the profile 4. The position of coding element 5 is then sensed by optical sensors (not shown). The code-setting unit 2 has a plurality of code setting elements 9 one for each coding element in code unit 1.

Coding System

The present coding system is intended to be used in connection with a system containing several robot workstations along a line, where pallets are used for supplying materials and tools to the work stations. The coding system, consisting of code unit 1 and code-setting unit 2, is fixedly mounted onto the pallet 3 and comprises a profile 4, having a suitable number of coding elements 5. These coding elements are adjustable by code-setting element 2 into upper position 6 and lower position 7. When coding element 5 is in upper position 6, a reflex tape 8 is exposed, the tape being attached to the profile 4. The position of coding element 5 is then sensed by optical sensors (not shown). The code-setting unit 2 has a plurality of code setting elements 9 one for each coding element in code unit 1. Every code-setting element 9 having means 10 displacable by electromagnet 11 from an upper position to a lower position. The electromagnet is operated by signals from the system assembly computer. Means 10 is provided with protrusion 12 and a leafspring 13 for interaction with the code element. The code-setting unit 2 is placed in such a way that when a pallet is docked in a workstation, code unit 1 with coding elements 5 will be in cooperative relationship with code-setting unit 2. In order to set a code combination all electromagnets are activated, thereby bringing every coding element into the lower position. The protrusion 14 of code element 2 is then caught...
