Abstract

PURPOSE:To provide a change tool magazine device of a NC router, which allows to change tools of a plurality of working heads with one tool changing device. CONSTITUTION:In the neighborhood of the side of a beam structural body 1, a tool magazine 14, in which a plurality of tools are provided, is installed. Further, a carrying stand 6, onto which a tool changing device is installed so as to move vertically and horizontally, is arranged between the tool magazine 14 and the neighborhood of a table 5. Under the above-mentioned state, in the change tool magazine, a tool changing device 7 pinches a tool in the tool magazine 14 so as to change the tool unloaded from one of working heads 3a, 3b and 3c of the head structural body 4 of an NC router for the tool in the tool magazine. Accordingly, no tool magazine per working head is necessary and the weight of the head structure body 4 can be reduced and the body 4 is miniaturized.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool change magazine device for an NC router having a plurality of machining heads, which can be replaced by a single tool changer.

[0002]

2. Description of the Related Art In a conventional NC router, a tool magazine is provided in the vicinity of a machining head, and a tool clamped by the machining head is removed between the machining head and the tool magazine.
An exchanging device is provided for exchanging the tool held in the tool magazine and attaching it to the machining head.

[0003]

In the conventional NC router configured as described above, since the tool magazine is provided for each machining head, the shape of the head structure becomes large and the weight becomes heavy and the head structure becomes heavy. There was a problem that a large amount of power was required to move the.

[0004]

According to the present invention, a head structure provided with a plurality of processing heads moves along a rail provided on a beam structure on a table for positioning a plate to be processed, In the NC router adapted to process the plate to be processed, a tool magazine provided with a plurality of tools is installed in the vicinity of the beam structure, and a carrier is provided between the table and the tool magazine. A tool exchanging device capable of transferring and exchanging the same number of tools as the processing heads is mounted on the transfer table so as to be transferable.

[0005]

In the present invention, a large number of tools are held in the tool magazine installed near the beam structure, and the tool changer is movably installed on the carrier table provided between the table and the tool magazine. ing.

Then, when the tool exchanging device clamps a tool from every other tool holding part of the tool magazine by the tool clamping part and moves to the vicinity of the table, the machining head moves to the upper part of the tool exchanging device. After holding the tool from this machining head, the conveyed tool is attached to the machining head.

With this structure, it is not necessary to provide a tool magazine for each machining head, so that the head structure can be made lightweight and can be moved smoothly even with a small power.

1 is a side cross-sectional view of the tool changer and the tool magazine. A rail 2 is attached to the beam structure 1, and a head structure 4 in which a plurality of processing heads 3a, 3b, 3c are provided on the rail 2 is shown in FIG.
It is provided to move to the left and right.

A table 5 is provided below the processing heads 3a, 3b, 3c, and the table 5 is configured to move back and forth in FIG.

Further, a carrier table 6 is provided in the vicinity of the table 5, the carrier table 6 is installed substantially parallel to the rails 2 of the beam structure 1, and the tool changing device 7 is mounted on the carrier table 6 as shown in FIG.
It is provided to move to the left and right.

A circular tool holding plate 9 rotated by a motor 8 is mounted on the tool changer unit 7, and further,
Clamping members 9a, 9b, 9c, ...
, 9f are provided, and the tool exchanging device 7 is mounted so as to be movable along the carrier table 6 by the carrier roller 10 and the cylinder 11 provided in the carrier table 6.

Further, on the carrier table 6, a vertical cylinder 12 for moving the tool changing device 7 up and down, a machining head 3a,
A front-rear cylinder 13 that moves back and forth in the directions 3b and 3c is provided.

A tool magazine 14 is installed on the side of the beam structure 1 at a position apart from the table 5, and the tool magazine 14 is separated from a first rotary plate 16 rotated by a motor 15. A second rotary plate 17 rotatably mounted at a position is mounted, and a chain 18 is hung between the first and second rotary plates 16 and 17, and a large number of tool holders 19 are mounted on the chain 18. The tools 20 are held in the tool holders 19, respectively.

In the tool exchanging magazine device of the present embodiment having the above-mentioned configuration, the tool exchanging device 7 has the tool magazine 14
And the first of the tool magazine 14,
When the second rotary plates 16 and 17 are rotated by the motor 15 and a predetermined tool comes to the front of the tool exchanging device 7, the upper and lower cylinders 12 and the front and rear cylinders 13 are driven, and the tool holding portion 9 of the tool exchanging device 7 is driven. The tool 20 held by the tool holding portion 19 is clamped by the upper and lower cylinders 12 and the front and rear cylinders 1.
Return to the predetermined position at 3.

Then, the tool changing device 7 is moved by the cylinder 11 on the carrier table 6 and comes near the table 5 to stop and stand by, and when the head structure 4 stops above the tool changing device 7, Upper and lower cylinders 12 and front and rear cylinders 1
3 is driven, and the tool exchanging device 7 clamps the designated tool of the processing heads 3a, 3b, 3c by the clamping members near the clamping members 9a to 9f having the designated exchanging tool of the tool clamping plate 9,
In addition, the tool holding portion 9 is rotated and the designated tool 20 is attached to the processing head 3 removed, and the processing heads 3a, 3b, 3
Repeat the same operation for c and replace.

The tool 20 is replaced by the machining head 3a,
In some cases, all of 3b and 3c are performed in succession, or the tools of one or two machining heads are replaced, and further, three or more machining heads 3 can be provided in the head structure 4.

As described above, in the apparatus of this embodiment, the tool changing apparatus 7 is moved between the tool magazine 14 having a large number of tools 20 and the plurality of machining heads 3a, 3b, 3c.
Since 0 is replaced, there is no need to provide a tool magazine for each machining head as in the conventional case, and the head structure 4
Can be moved smoothly, and the size of the head structure 4 can be reduced.

[0018]

As described above, the NC router exchange tool magazine device of the present invention is configured such that the tool exchange device is moved by the carrier provided in front of the beam structure.
Since it is configured to move up and down and back and forth and to move between the tool magazine and the machining head to replace the tool mounted on the machining head, it is possible to replace each of the machining heads as before. It is not necessary to provide a tool magazine, and there are advantages that the head structure is light and the shape is small.
