Abstract
A blade storage array is detachably mountable with a tissue log cutting saw. The saw has a cutting arm with a tool holder receptacle adapted and configured to hold a circular saw blade for the saw. The array has a plurality of storage units. Each storage unit is adapted and configured to store a circular saw blade for the saw. Each storage unit has a tool holder receptacle adapted and configured to hold a circular saw blade. Each storage unit is adapted and configured to move perpendicularly to the saw blade center axis.
Claims16
A tissue log cutting saw having a blade storage array detachably mounted to a structure of the tissue log cutting saw, the blade storage array comprising:
- a plurality of storage units, each storage unit being configured to store a circular saw blade for the tissue log cutting saw, each storage unit having a tool holder receptacle configured to releasably secure a circular saw blade in the storage unit in a manner such that the circular saw blade defines a plane in the storage unit with the circular saw blades stored in the storage units within the array being aligned coaxially and in parallel planes that are axially spaced within the blade storage array, each storage unit being configured to reciprocate in a linear direction parallel to the plane of the circular saw blade in the storage unit into and out of an interior of the tissue log cutting saw when the array is detachably mounted to the structure of the tissue log cutting saw, each storage unit being configured to reciprocate in the linear direction independently of another storage unit, each storage unit being configured to exchange the saw blade between the tissue log cutting saw and the storage unit when the blade storage array is detachably mounted to the tissue log cutting saw.
A method comprising:
- providing an array with a plurality of storage units, each storage unit being configured to store a circular saw blade for a tissue log cutting saw, each storage unit being configured to exchange a circular saw blade with the tissue log cutting saw when the blade storage array is detachably mounted to the tissue log cutting saw, at least one storage unit in the array being devoid of a circular saw blade, each storage unit having a tool holder receptacle configured to releasably connect with a tool holder of a circular saw blade, other storage units of the array each being provided with a circular saw blade releasably secured on the tool holder receptacle of the respective storage unit in a manner such that the circular saw blade defines a plane in the storage unit with the circular saw blades stored in the storage units within the array being aligned coaxially and in parallel planes that are axially spaced within the array, each storage unit being configured to reciprocate in a linear direction parallel to the plane of the circular saw blade in the storage unit, and each storage unit being and configured to reciprocate in the linear direction independently of another storage unit.
A method comprising:
- providing a plurality of circular saw blades, each of the circular saw blades defining a plane with first and second sides of the respective circular saw blade on opposite faces of the plane, each of the circular saw blades having a center axis of rotation, each of the circular saw blades having a tool holder mounted to the respective circular saw blade at the center axis of rotation, the tool holder extending outward from the first and second sides of the respective circular saw blade;
- providing an array with a plurality of storage units, each storage unit in the array having a tool holder receptacle being configured to releasably connect with the tool holder of at least one of the circular saw blades for storage of the circular saw blade within the storage unit, and each storage unit in the array being configured to reciprocate in a linear direction parallel to the plane of the circular saw blade stored in the storage unit, each storage unit in the array being configured to reciprocate in the linear direction independently of another storage unit;
- releasably connecting at least two circular saw blades in respective storage units via the storage unit tool holder receptacle and the tool holder on the second side of the respective circular saw blade in a manner such that the tool holder on the first side of the respective circular saw blade is exposed and configured for releasable connection with a tool holder receptacle of a cutting arm of a saw, and the respective circular saw blade is aligned coaxially and axially spaced in parallel planes with the other circular saw blade stored in the respective other storage unit within the blade storage array.
