The present invention relates to a tool delivery device suitable for a dual type tool magazine, and more particularly, a dual configuration in which a tool magazine having a large number of tools in a machining center is configured to be suitable for the transfer relationship of a tool change according to the dual type. It relates to an automatic tool transmission device of a type tool magazine.

In the conventional dual type tool magazine, as shown in FIGS. 1 to 4, two magazines having the same structure are configured in parallel, and guide bars having horizontally connected to each other on the upper side of the first tool magazine and the second tool magazine are installed. And slidingly coupled to the guide bar so as to be included in each upper range of the first tool magazine and the second tool magazine by the operating stroke of the transfer cylinder installed at the fixed end of the first tool magazine, and the tool transport port is configured in front of the coupling. Tool feed means are configured.

The first tool magazine is arranged so as to be orthogonal to the tool boy transporting the tool of the magazine to the tool change position of the machine body, and the tool transport port of the first sub changer and the tool transport means serving to pick up the tool of the magazine to the tool boy. A second sub-changer is fixedly installed perpendicular to the one tool magazine and transfers the tool of the tool feed port to the empty tool port of the first magazine or vice versa.

The second tool magazine is fixedly installed perpendicular to the second tool magazine so as to be orthogonal to the tool transport port of the tool transport means moved to the second tool magazine side, and transfers the tool of the second tool magazine to the tool transport port or vice versa. It is comprised including the 3rd sub changer which drives.

When a signal for picking up a specific tool on the side of the second tool magazine 10-2 is applied, the tool holder 12-2 of the second tool magazine 10-2 first drives the hydraulic motor and the sprocket 11-2. The tool of the desired tool port 13-2 is stopped at a position perpendicular to the third sub changer 50 while moving by.

When the transfer cylinder 31 is driven by the control flow at the same time or continuously, the feed slider 33 in the state of the empty tool feed port 34 reaches the standby position for the tool transfer on the guide bar 20. . (See Fig. 1)

Subsequently, while the vertical cylinder 52 and the horizontal cylinder 56 of the third sub changer 50 are driven by a constant control flow, the tool of the tool port 13-2 as the tool gripper 57 is used as a tool feed port ( 34). (See Fig. 4)

The operation control flow thereof is such that the vertical cylinder 52 is stopped when the sensing dog 54a at the end of the positioning bar 54 reaches the vertical position detecting switch 55b. (Gripping the tool)

Subsequently, the horizontal cylinder 56 is driven, and the gripper bracket 57a stops by reaching the horizontal position detecting switch 58b. (A state in which the gripped tool is picked up)

Then, as the vertical cylinder 52 is driven again, the sensing dog 54a stops at the position 55b to 55c of the vertical position sensing switch (the state before the picked-up tool is inserted into the tool feed port).

Subsequently, the horizontal cylinder 56 is driven again, and the gripper bracket 57a stops by reaching the horizontal position detection switch 58a. (The tool is inserted into the tool feed port.)

When the tool is transported by such an operation control flow, the vertical cylinder 52 is finally driven to reach the initial state where the sensing dog 54a stops at the vertical position detecting switch 55a.

On the other hand, the feed slider 33 of the tool transfer means 30, which received the tool, is the first tool magazine 10-1 by the reverse operation of the transfer cylinder 31 with the tool in the tool transfer port 34. Stop at the end of the range.

Subsequently, the tool holder 12-1 is moved so that the empty tool port 13-1 in the first tool magazine 10-1 reaches the standby position for tool change.

At this time, the vertical cylinder 42 and the horizontal cylinder 46 of the second sub changer 40 are driven by a constant control flow, and the tool of the tool feed port 34 is driven by the tool gripper 47 to the first tool magazine 10. It is attached / removed to the empty tool port 13-1 of -1).

More detailed operation control flow thereof causes the vertical cylinder 42 to stop when the sensing dog 44a at the end of the positioning bar 44 reaches the vertical position detecting switch 45c. (Gripping the tool of the tool feed port. One state)

Subsequently, the horizontal cylinder 46 is driven, and the gripper bracket 47a stops by reaching the horizontal position detecting switch 48b. (Grip picked up tool)

Subsequently, while the vertical cylinder 42 is driven downward again, the sensing dog 44a stops by reaching the position 45c to 45b of the vertical position detecting switch (state before the picked-up tool is inserted into the tool port).

Subsequently, the horizontal cylinder 46 is driven again, and the gripper bracket 47a reaches the horizontal position detecting switch 48a and stops. (The tool is inserted into the tool port.)

When the tool is transported by such an operation control flow, the vertical cylinder 42 is driven to finally reach the initial state where the detection dog 44a stops at the vertical position detection switch 45a.                         

On the other hand, when the desired tool input step is completed in the tool port 13-1 of the tool holder 12-1, the tool holder 12-1 is moved to move between the first sub-changer 14 and the tool boy 15a. The tool is moved to the position of and stops, and the tool is transferred to the tool boy 15a by the driving of the first sub changer 14 having the same concept as the second third sub changer, and finally by the tool boy cylinder 15b. It will be delivered to the machine body.
