摘要： A pneumatic bar feeding apparatus for advancing a length of bar stock to a CNC center machine for processing and including a pair of concentric tubular members which are housed in a housing supported by a pair of vertical spaced apart support stands. The inner tubular member is spaced from the interior surface of the outer tubular member by at least three bearing and bushing devices which are located at three separate locations. A rear end of the inner tubular member is airtightly sealed so that air pressure does not leak out. An actuating assembly is movably installed within the inner tubular member and includes a slidable piston, a rod connected to the piston and a coil spring which surrounds the rod and biasing the rod from entering into a bar carrier which is also movably installed within the inner tubular member. The bar carrier comprises a plurality of step-down interior portions for accommodating a plurality of different size diameters of the bar stock. The inner tubular member is adapted to receive the bar stock therein such that one end of the bar stock is fitted within one of the plurality of step-down interior portions. The pneumatic bar feeding apparatus does not generate noise and vibration because the bearing and bushing devices prevent the inner tubular member from striking the interior surface of the outer tubular member and also prevent it from vibrating within the outer tubular member.

摘要： An automatic pneumatic bar feeding apparatus for automatically feeding a plurality of bar stocks to a work station, such as a computer numerical control (CNC) machine for processing, thereby eliminating the need to reload the bar feeding apparatus with another bar stock one at a time. The bar feeding apparatus comprises a rotary which turns a loading unit 45° to a loading position for loading a bar stock onto the loading assembly from a holding tray. After the bar stock has been loaded onto the loading assembly, the rotary turns the loading assembly back to its initial position or feeding position. A pneumatic motor supplies air to a rear feeding assembly, wherein the feeding assembly pushes the bar stock to the work station for processing. When the feeding assembly has fed the majority of the bar stock into the CNC machine, the rotary turns the loading assembly back to the loading position. A hollow tube will then be aligned with the center of the CNC machine, where a rod slidably located within the hollow tube further pushes the excess bar stock into the CNC machine through the hollow tube until a sensor indicates that all of the bar stock has been processed by the CNC machine. When the feeding is completed, the feeding assembly returns to its initial position. During this feeding process, another bar stock is being loaded onto the loading assembly and when the previous bar stock has been successfully machined, the bar feeding apparatus will begin the process again with the new bar stock.
