As such, as each tool is accommodated in the tool storage unit through the tool port of the matrix type tool carrier and the tool moving part of the conventional machine tool, the tool port must be separately manufactured for each tool, so manufacturing costs and time are high. However, there was a problem that caused inconvenience to workers.

In addition, as the matrix-type tool holder and the tool moving part of the conventional machine tool store the tools in the tool storage unit through the tool port, when the tool port is not accurately seated in the tool storage unit, tool fall due to malfunction or tool collision may occur. There was a problem in that equipment damage or tool damage occurred, increasing maintenance costs, and causing safety accidents.

Moreover, as the tool moving part does not directly grip the tool but moves by indirectly gripping the tool port, the matrix-type tool support and the tool moving part of the conventional machine tool gradually move to prevent collision with the tool, and the tool moving part As it moves only in the horizontal and vertical directions, which are the defined movement paths (A), in FIG. 3, it moves vertically downward (path ①) to move the tool located in the opposite tool storage from the tool storage at the top right in FIG. , it must move horizontally to the left (path ②), and finally move vertically upward ( route ③). In other words, even when loading/unloading tools in the tool storage area, it is impossible to move at high speed to prevent collisions, and the tool storage area for replacement must be moved in a complicated manner only with a pre-determined movement path, which consumes a lot of time for tool replacement. Finally, there is a problem in that the productivity of the machine tool decreases as the non-machining time increases.

In addition, there are problems in that the space utilization is reduced due to the narrow tool storage space of the matrix-type tool holder and the tool moving unit of the conventional machine tool, and the stability and reliability of the machine tool due to malfunction are reduced.

That is, the receiving part and the gripping part of the main body directly grip the shank part and the pull stud of the tool, not the tool port of the tool.

Then, as shown in FIG. 9 , when the actuator unit 243 operates to move the rod unit 242 backward under the control of the controller, the gripping unit 244 closes and presses the pull stud 72 to clamp the tool, and the holding unit Even in a state in which the actuator unit 243 is moved backward by 245, a state in which the pull stud portion of the tool is pressed and clamped by the gripping unit is maintained.

Conversely, in order for the gripper unit to unload the tool to the tool changing unit or to the tool holder unit, the opposite operations may be sequentially performed so that the tool can be quickly and accurately unloaded.

As described above, in the tool feeder of the machine tool tool support and the tool support for the machine tool including the same according to the present invention, the gripper not only moves in conjunction with the transfer in the horizontal and vertical directions by the transfer unit, but also moves in the horizontal or vertical direction of the transfer unit. Independently moving backwards and forwards in the width direction, the tools stored in the tool holder part of the tool compartment are directly gripped instead of the tool port, thereby excluding the tool port to reduce manufacturing costs and moving the tools to the tool holder part of the tool rack. As quick and accurate loading/unloading is possible, malfunctions can be prevented and the stability and reliability of machine tools can be improved.

In addition, the tool carrier of the machine tool tool carrier according to the present invention and the tool carrier of the machine tool including the same grips the tool while the gripper moves forward and backward in the width direction independently of the horizontal or vertical movement of the transfer unit. In order to grip the tool stored in the tool holder part of the tool holder in the state where the tool is not clamped, the tool change time is reduced as the gripper part can be moved in the shortest distance, and the productivity of the machine tool is reduced by reducing the non-processing time. It is possible to maximize the operation and structure of the gripper part and the structural change of the tool holder part to prevent tool damage or equipment damage during tool exchange, thereby reducing maintenance cost and time and promoting operator convenience.
