2.3 Tool Stand Design

In most cases, the tools are stored in a tool stand when not being used by the robot. During

coupling and lock-up the tool stand must allow for movement (float) in a plane parallel with the

mating surfaces of the Master Plate and Tool Plates (X and Y). Even slight misalignment

between the Master Plate and Tool Plate can generate high forces during lock-up if the Tool

Plate is not allowed to float into place during lock-up. These high forces can cause excessive

wear and even jamming of the end effector and robot. The degree of float required depends on

the accuracy of the robot's positioning and the repeatability of the tool location in the tool stand

during lock-up. See Figure 2.2 and Table 2.1 for recommended maximum allowable float

(offsets) prior to coupling. The tool stand should be designed to minimize misalignment during

coupling and uncoupling. In some cases greater offsets than shown in Table 2.1 can be

accommodated by the Master and Tool Plates, but will increase wear.

Ideally, the tool should be hanging vertically in the tool stand so that gravity acts to uncouple

the Tool Plate from the Master Plate during unlocking. It is possible to design tool stands that

hold tools in the horizontal position, but care must be taken that the necessary compliance is

provided during coupling and uncoupling. In general, "horizontal-position" tool stands cause

more wear on the locking mechanism and locating features of the tool and tool stand.

Lock-up should occur with the Master Plate in the No-Touch™ Locking zone (see Table 2.1)

but not touching the Tool Plate. As locking occurs, the Master Plate should draw the Tool Plate

into the locked position.

Tool stands may also need to incorporate means for covering tools and electrical modules to

protect them in dirty environments such as grinding or welding. Alternatively, locating tool

stands in areas shielded from weld spatter, fluids, adhesives or other debris would eliminate the

need for tool covers.

CAUTION: Tool stand design is critical to proper operation of the Tool

Changer. Improperly designed tool stands can cause misalignments that

will cause jamming and/or excessive wear of Tool Changer components.

CAUTION: During coupling and lock-up, the tool stand must allow for

movement (float) in a plane parallel to the mating surfaces of the Master

plate and Tool plate(s), and in a direction to this plane towards the Master

plate.
