Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a method for setting a cutting width in a cutting machine.

In sawmilling, both ends of the wood in the longitudinal direction are sometimes cut, and this operation is usually called ``tome!uJsuJ''.The distance between the cut parts is called the ``trim width J''.

The cutting work is carried out using a conventional cutting machine, which consists of a long box-shaped base with a fixed support equipped with a 9J cutting blade attached to one end of the base. A movable branch equipped with a UJ cutting blade is constructed so that it can approach and move away from a fixed support. During the cutting process, a wooden ruler called a reference panel with the same length as the selected cutting width is used. First of all, this 11f' support + F'< 1. Get up at the initial setting position 71', which is far away from the fixed support, and approach the 11th lower skin pillar to the fixed support with one end in the longitudinal direction of the reference panel (in contact with the moving panel). Now, when the other end of the reference panel that is pushed and moves touches the fixed branch;
At step 6, stop the support and place it in a temporary position. Then, in this state, the distance of the νJ shearing force of the 1.1 branch becomes equal to the retaining width selected once.

But such a traditional stop! , there are some major drawbacks to the 1-width fixation system in the 1J'J machine.

First of all, if you have 10 ton of wood, even if the width of the cutter is round, next month's 1) I! Using the reference panel for the work percentage of μ 1■1νJ, cut off □□□, 1. This means that there is a need to carry out a death penalty. This is a very tedious task, and in many cases requires one worker per one sintering machine. Stay again.”
Naturally, different reference panels will be used for different widths, or in the case of low-volume, high-mix production, it is not only necessary to prepare a large number of reference panels, but also to select and use them in a predetermined order without error. This places an additional burden on 1'1 karma. Furthermore, since the reference panel mentioned in 1 is made of Tsutomi wood, it may wear out during repeated use, and furthermore, it expands and contracts depending on temperature, humidity, time, and season, so it does not hold up well. It is easy to make errors in the cutting width.

An object of the present invention is to facilitate, speed up, and automate the setting of the cutting width in a cutting machine.

Another object of the present invention is to provide a 1p4. The aim is to completely eliminate the influence of the standard panel's 1 method on the j setting.

That is, in this invention, the first detection means ++
The amount of movement of the moving column f is detected to form first electrical data, and the first stage of second detection detects that the reference panel pushed by the moving column 11 has come into contact with the fixed branch, and the second electrical data is generated by detecting the amount of movement of the moving column f. The first and second detection stages are connected to the input end of the control device, and the drive mechanism of the movable column is connected to the output side, and the second electrical data is generated manually. At this time, the control device 1 stops the drive mechanism by the operation t), and the 10th period air data at that timing is stored.

The present invention will now be described in more detail with reference to embodiments shown in the drawings.

The small figure shown is an example of the cutter of the present invention, in which a fixed support 21 is fixed upright near one end of one side of a long and narrow box-shaped base l. This 1-11 fixed branch 21 supports a reno shearing force 22, and is driven by a motor 23 installed on this νJ cutting blade 22 to rotate, and is also driven by a fluid pressure cylinder 24. .

A pair of kite rails 2a and 2b are fixed to the inner end of the base ■ in the l-u'ii beak + i direction, extending along almost the entire length. The 1+ (moving support 31) is engaged at the bottom so that it can move in the r direction. motor 3
3 and rotates, and the fluid pressure cylinder 3
4]-F moves.

A beam reversing motor 3 and a speed reducer 4 are installed on the movable support side end of the base l, and the output of the speed reducer ←b5 extends between the two guide rails 2a and the movable support 31.
It is threadedly engaged with a screw nut 35 formed at the bottom of the holder. Therefore, when the output shaft 5 is rotated by being driven by the motor 3, the movable support 31 moves in the longitudinal direction of the base, approaches or moves away from the fixed support 21, and accordingly, the width of the stay glue is determined according to the wood W. is set.

A span member 6 is sunk across the gap between the two guide rails 2a on the base surface, and the moving support column 31
When pushed, the reference panel P moves this distance and approaches the fixed column 211. In addition, the base of the fixed support) 21 has an opening f.
A limit switch 25 is provided facing the moving column 31, and detects the arrival of the panel P), 1: /ll-.

The configuration and operation described above are common to conventional vJ machines.

In addition to the configuration described above, the cutter of the present invention uses a control device, a magnetic scale, and a magnetic scale data processing unit.

This control device +W:'41 is electrically connected to the glue mint switch 25 on the fixed column side and the main motor 3 at the end of the base. A magnetic scale 51 is provided on the side surface of the nol stand l extending in the longitudinal direction, and the movable support 31
A head 52 protruding from the side surface of the base faces this. This point 52 moves along with the magnetic scale 41 as the moving column 31 moves to the base 1, and generates an electric signal (magnetic scale data) proportional to the movement 1. It is. Connect the input terminal to 1.52 for the Zugenent scale data processing unit Toro 1.
Each output side is electrically connected to the control device 51.

Next, the operation will be explained. First, a hex panel P corresponding to the width of the cutout of the wood W is placed on the span material 6-1-, and one end thereof is brought into contact with the base of the IIf moving branch 31 at the initial setting position. Next, when the worker presses the switch or button IM fa on the control device 41 to start the 1-motor 3, the movable column 31 moves on the base 1 while pushing the reference panel P and approaches the fixed column 21. . Along with this, the spatula 1552 moves along the magnetic scale 51, and the data indicating one movement (that is, the amount of movement of the moving column 31) is obtained from the open side and the magnetic scale data processing unit 1-6.
1. At this point, the processing unit 61 accumulates data indicating the amount of movement. Also, the control device 4
Magnet processing data unit 6 from memory in 1
1 is open, and no data is read into the former.

When the movable support 31 moves further and the other end of the pushed reference panel P hits the rim switch 25 on the fixed support, the control device 41 operates in response to the signal 1) from the rim I switch. Since the motor 3 is stopped at P;, the movable column 31 is also stopped at that position. do. At line 511, in the control device 41, a circuit connecting the memory to the magnet scale data processing unit 61 is closed, and the processing unit 61 is connected to the memory in the control device 41 (random access memory). Data indicating the total movement of the 11th lower skin column 31 is read (preferably high speed). This data corresponds to the cutout width selected for the wood W.

By repeating the above operation 1- using reference panels P corresponding to various mitering widths, data corresponding to the various mitering 111I, i is accumulated in the memory of the control device 41. Therefore, when I started the actual work, I decided to use a certain length of wood. Once the ilJ width is determined, the data corresponding to it is read out from the memory in the control device 41 (for example, it is temporarily stored in a comparator, etc.), and the data is sent to the hend 52 via the data processing unit 61 at the start of the stop cutting operation. It is a good idea to compare the manual movement!tl with the small data and when the two become equal, stop the motor 3. That is, set the /\-doware of the control 211 device 41 in such a way. As long as you do this, there is no need to use a reference panel every time you do the cutting work.

In the example of 1- below, the movement of the fil moving support; 11 is detected by a magnetic scale, and the amount of movement of the movable support (11) is detected by a limit switch and a tosswitch. are doing. However, the present invention is not necessarily limited to these detection means, and any detection means may be used as long as it has the function of sending the amount of movement as shown in L to the control device as data in the form of an electrical signal. There may be.

There are several advantages in the case according to this invention.

First, use a reference panel with accurate dimensions to correspond to the width of the cutout. Once the data indicating the appropriate amount of movement of the moving column is read into the memory of the control device, there is no need to use the reference panel every time the work is carried out. This not only simplifies the work, but also means that it is completely unaffected by the expansion and contraction of the reference panel due to temperature, humidity, season, and aging.

In addition, when detecting the amount of movement of the +in branch using a magnetic scale, very high precision data is obtained, and the control device operates based on this data, so the error in the ~1'1 J width becomes noticeable. It's going to be small.

Changing the cutout width can be done by simply reading data from a different memory in the control device, and can be done very quickly and easily if a random access memory is used. In this case, the number of possible tie widths is medium, several hundred to several thousand at most, so memory coalescence does not have to be very large; rather, only the access ties and memory cycles should be taken into consideration. It can be used to increase speed and the memory size does not need to be increased. In addition, even if there are cases where the fastening width changes frequently and complicatedly with a wide variety of products, it is possible to quickly and easily set the appropriate progera to the I-me control device. You can change sl1M+l. Furthermore, if the control device is provided with arithmetic functions, initial settings are no longer necessary.
