Loader Arm Assembly Options

Shuttle Nest/Parts Catcher Assembly

Shuttle Nest-Parts Catcher Assembly
This option is recommended for parts that lay horizontal to the lathe centerline, with no assistance, and which do not require sensitive handling after machining. These parts typically roll, slide, or hang by their heads on their own at a minimum incline of 20 degrees. These parts can be nested easily and can be inserted in the work holding to maximum depth of 6 inches. The parts catcher, mounted directly ahead of the nest, results in the most efficient unloading. Upon entering the work envelope, the parts catcher assembly advances to the spindle centerline and the finished part is ejected into the parts catcher. The shuttle nest then advances to the load position and the raw part is placed in the work holding. Upon exiting the work envelope, the parts catcher places finished machined parts, via a trap door, onto a Toellner-supplied conveyor leading to an accumulation table or other accumulation system specified by you. Use of a parts catcher requires a through-spindle part ejector supplied by Toellner. Please note: For each separate part diameter to be loaded, an individual nest or gripper jaw set must be constructed.

 

 

Opposing Gripper Assembly

Opposing Gripper4
This option is recommended for holding parts in a precise attitude while they are shuttled into the work envelope. Ideal for shorter parts that do not easily lay horizontally and which require sensitive handling after machining. This gripper assembly contains two grippers opposing each other on a 3-position wrist (0, 90, & 180 degree stop positions) mounted on a z-axis slide. Upon entering the work envelope, the unload gripper advances to the spindle centerline and removes the finished part. The gripper assembly then rotates 180 degrees to the load position and the raw part is placed in the work holding via the load gripper. Upon exiting the work envelope, the unload gripper, in a controlled manner via the 3-position wrist, places finished machined parts gently onto a Toellner-supplied conveyor leading to an accumulation table or other accumulation system specified by you. Please note: For each separate part diameter to be loaded, an individual nest or gripper jaw set must be constructed.

 

 

Adjacent Gripper Assembly

Adjacent-Grippers1
Use this option for holding parts in a precise attitude while they are shuttled into the work envelope. Ideal for shorter parts that do not easily lay horizontally. Gripper assembly contains two grippers adjacent each other mounted on independent z-axis slides. Upon entering the work envelope, the unload gripper advances to the spindle centerline and removes the finished part. The load gripper then advances to the load position and the raw part is placed in the work holding. Upon exiting the work envelope, the unload gripper places finished machined parts onto a Toellner-supplied conveyor leading to an accumulation table or other accumulation system specified by you. Please note: For each separate part diameter to be loaded, an individual nest or gripper jaw set must be constructed.

 

 

Gripper/Parts Catcher Assembly

This option is ideal for holding parts in a precise attitude while they are shuttled into the work envelope and which do not require sensitive handling after machining. Ideal for shorter parts that do not easily lay horizontally. Gripper/parts catcher assembly contains one gripper mounted on a z-axis slide adjacent to a parts catcher. The parts catcher, mounted directly ahead of the gripper, results in the most efficient unloading. Upon entering the work envelope, the parts catcher advances to the spindle centerline and the finished part is ejected into the parts catcher. The gripper then advances to the load position and the raw part is placed in the work holding. Upon exiting the work envelope, the parts catcher places finished machined parts, via a trap door, onto a Toellner-supplied conveyor leading to an accumulation table or other accumulation system specified by you. Use of a parts catcher requires a through-spindle part ejector supplied by Toellner. Please note: For each separate part diameter to be loaded, an individual nest or gripper jaw set must be constructed.

 

 

Shuttle Nest/Gripper Assembly

Shuttle Nest Gripper3
Use this option for parts that lay horizontal to the lathe centerline, with no assistance and require sensitive handling once machined. These parts typically roll, slide, or hang by their heads on their own at a minimum incline of 20 degrees. These parts can be nested easily and can be inserted in the work holding to maximum depth of 6 inches. Upon entering the work envelope, the gripper advances to the spindle centerline and removes the finished part. The shuttle nest then advances to the load position and the raw part is placed in the work holding. Upon exiting the work envelope, the gripper places finished machined parts onto a Toellner-supplied conveyor leading to an accumulation table or other accumulation system specified by you. Please note: For each separate part diameter to be loaded, an individual nest or gripper jaw set must be constructed.

 

 

Shuttle Nest with 180° Part Rotation & Reload

180 Degree Turn-Around 2
This option allows two operations to be completed on a single spindle. It is ideal for parts that lay horizontal to the lathe centerline, with no assistance. These parts typically roll, slide, or hang by their heads on their own at a minimum incline of 20 degrees. These parts can be inserted into the work holding to maximum depth of 6 inches. After first operation machining is complete, the part is ejected back into the shuttle nest, rotated 180 degrees, and reinserted into the work holding for second operation machining. After second operation machining is complete, the parts catcher assembly advances to the spindle centerline and the finished part is ejected into the parts catcher. The shuttle nest then advances to the load position and the raw part is placed in the work holding. Upon exiting the work envelope, the loader places finished machined parts onto a Toellner-supplied conveyor leading to an accumulation table or other accumulation system specified by you. This option requires a through-spindle parts ejector supplied by Toellner. Please note: For each separate part diameter to be loaded, an individual nest or gripper jaw set must be constructed.

Gripper with 180° Part Rotation & Reload

This option allows two operations to be completed on a single spindle. It is recommended for holding parts in a precise attitude while they are shuttled into the work envelope. After first operation machining is complete, the gripper turns the part 180 degrees and reinserts it into the work holding for second operation machining. After second operation machining is complete, the parts catcher (or unload gripper, depending on the part) advances to the spindle centerline and the finished part is removed from the work holding. The load gripper then advances to the load position and the raw part is placed in the work holding. Upon exiting the work envelope, the loader places finished machined parts onto a Toellner-supplied conveyor leading to an accumulation table or other accumulation system specified by you. This option requires a through-spindle parts ejector supplied by Toellner. Please note: For each separate part diameter to be loaded, an individual nest or gripper jaw set must be constructed.

 

 

Shuttle Nest for Loading between Centers

Load Between Centers
This option is necessary for parts that lay horizontal to the lathe centerline with no assistance, are machined between centers, and held by work holding and tailstock center. These parts typically roll, slide, or hang by their heads on their own at a minimum incline of 20 degrees. Parts are presented to spindle centerline while the tail stock advances to hold the part between centers. For unloading, the loader advances to the part catch position, the work holding releases and tailstock retracts, allowing part to fall into part catcher (or nest if a sensitive or heavy part). Loader then advances to load position, the tail stock advances and work holding closes. Upon exiting the work envelope, the loader places finished machined parts onto a Toellner-supplied conveyor leading to an accumulation table or other accumulation system specified by you. Please note: For each separate part diameter to be loaded, an individual nest or gripper jaw set must be constructed.
