Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention [Field of Industrial Application] The present invention relates to a straightening and cutting device, and more particularly to a straightening and cutting device for straightening a coil wound around a bobbin and cutting it into a predetermined length.

Are known. Such a coil material straightening/cutting device is equipped with a straightening means in order to correct the winding curl of the coil material caused by being wound around the bobbin, and is also provided with a stopper for setting the cutting length of the coil material. The structure is such that a coil material of a predetermined size is cut out by repeatedly cutting the coil material when it abuts against the coil material.

[Problems to be Solved by the Invention] However, the conventional coil material straightening and cutting device has the following problems. That is, (1) In order to obtain various cutting lengths by 1q, the operator must change the position of the stopper of the coil material feeding device each time, which requires troublesome work.

(2) Since two or more coil materials are cut at once, the cutting rate may be poor depending on the number of coil materials required after cutting. For example, if the number of coils is 3 and the number of coils required to be cut is 40, the number of coils that are actually cut to the specified length will be 42, which is an integer multiple of 3, and 2 will be wasted. .

Next, the processing performed in the above-mentioned control circuit 100 will be explained with reference to the flow chart shown in FIG.

This coil material straightening and cutting device is powered on, and settings such as the cutting length of the coil material W are performed from the terminal 106.
When the operation is started, first, the tip of the coil material W is brought out. Next, the coil material cutting control routine shown in FIG. 4 is executed together with other control routines. step 200
Then, it is determined whether the rear end detection switch 2 is in the on state, and if the rear end has not been detected, the process proceeds to step 21.0. The switch 2710 is used to switch the keyboard 10 in advance in another control routine (not shown).
Coil material W input from 6 and stored in RAM 103 etc.
In the feeding (2), the cutting length is not read out and processing is performed. In the subsequent step 220, the vice stand 21 holding the coil material W is driven according to the cutting length read out in step 210, and the coil material W is fed a predetermined length. When the vice table 21 feeds the coil material W, the coil material W is drawn out of the straightening device 3. Annular bell I of orthodontic device 3
~ 14a, 14b are presser plates 13a, 13b, t: which receive the pressing force and grip the coil material W. The coil material W is pulled out against this force, thereby being squeezed and curling habits etc. are corrected. . The feeding amount of the coil material W is determined by the encoder 24

When the pulse signal inputted from the encoder 24 is detected by counting, etc., the feeding of the pipe is stopped, and in step 230, the hydraulic cylinder 7 is driven and the vice 8 is
A process of holding and fixing the coil material W is performed.

In the following step 240, data input from the keyboard 106 in advance in another control routine (not shown) is stored in the RAM 103.
The cutting conditions of the coil material W stored in the etc., for example, the rotation speed,
The feed amount and feed speed are read and V processing is performed. Next, in step 250, the cutter drive motor 26 is driven to cut the cutter 25 according to the cutting conditions read out in step 240.
is rotated at a predetermined number of rotations, the transfer motor 29 is driven, and the cutter head 10 is transferred at a predetermined sending signal and feeding speed. The rotation speed is accurately detected by the encoder 28 and controlled so that the rotation speed of the cutter drive motor 26 is a predetermined rotation speed.

Roughly speaking, the feed foot and feed speed are accurately detected by the encoder 30, and controlled so that the feed pitch and feed speed of the cutter head 10 become a predetermined feed base and feed speed.

The operation of the cutter 25 disposed on the cutter head 10 is shown in the cutter operation explanatory diagram of FIG. The cutter 25 is rapidly fed from its original position by a preset feed fia, that is, to the vicinity of the uppermost coil material W, at a preset speed (hereinafter referred to as cutting speed) to suitably cut the pipe material. ) and only ibl is sent. When the cutting of the first coil material W is completed, the cutter 25 is fast-forwarded again, and the above operation is repeated one after another until the lowest coil material W is cut. In addition, the above-mentioned feed Ha, bi to b4
．． CI to C4 and cutting speed are accurately detected by encoder 30. When it is detected by counting pulse signals inputted by the encoder 30 that the cutter 25 has been moved to the position where cutting of the four coils (71W) is completed, cutting of the coil material W is completed and the cutter head 10 returns to the original position.

When the cutting is completed, the process advances to step 260. In step 260, the number of cuts is counted and compared with a preset number of cuts. If the number of cuts actually cut is less than the preset number of cuts, they can be handled as rNEXTJ, and this control routine ends once. If the actual number of cuts matches or exceeds the preset number of cuts, it is handled as rENDj (button) and ends this control routine. Here, it is handled as rNEXTj [if it is , as long as the trailing edge detection switch is in the Δ-on state, the judgment in step 200 will be "NO", so the processes of steps 210 to 260 described above will be repeated. Therefore, the cutting length read out from the RAM 103 According to the cutting conditions, coil material W of a predetermined length is cut out from the coil +, (W wound on the bobbin 1 one after another.

When the coil material W is fed and the rear end of the coil +AW is detected by the rear end detection switch 2, step 200
The determination of the rear end detection is rYEsJ, the cutting of the coil material W is completed, and the coil material straightening and cutting device is stopped.

As described above, the coil material straightening and cutting device of this embodiment has a simple configuration, but it can feed the four coil materials W wound around the pobbin 1 while straightening them at once, and perform preset cutting. It can be cut one after another in length. In addition, since the feed rate, feed suspension, and rotational speed of the cutter head 10 are suitably controlled during cutting, the coil material W can be cut well in a short time.

Further, in the coil material straightening and cutting device according to the present invention, since the feed radius of the cutter head 10 can be set in advance, various cutting lengths can be obtained at the same time. Next, operations for obtaining various cutting lengths will be explained. FIG. 6 is a setup diagram of the coil material W, and this figure shows a case where there are four coil materials W as an embodiment of the present invention.

As shown in the figure, the coil material feeding device 5 feeds the coil IJW by a preset amount ff1A, the cutter head 10 is transferred by the preset feeder, and the upper coil + JW3 is cut at the cutting length A. be done. Next, the coil material W is fed by a feeding amount IB, and the cutter head 10 is transferred by a preset feeder, and one upper coil vJW is cut at a cutting length B. The cutter head 10 is roughly fed by the feed amount C of the coil material W and is fed only by the preset feed rate.
is transferred and the 4 coils + JW are cut. As a result of the above operation, 3 pieces with cutting length A, 1 piece with cutting length B,
1 piece with cutting length C, 2 pieces with cutting length B + C, and 1 piece with cutting length A + B 10, 1q each.

Furthermore, according to this embodiment, the cutting length and cutting conditions of the pipe can be set in advance, so it is possible to perform unmanned/steady automatic operation, or to avoid unnecessary cutting using data stored in the backup RAM 104. It is also possible to perform an operation in which cuts are made with the same cutting length and number (6).

Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment in any way, and it goes without saying that it can be implemented in various forms without departing from the gist of the present invention.
