Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automatic size changing method in a cutting device, and more specifically, when changing the cutting setup of a sheet-like tire constituent material, the present invention relates to an automatic size changing method in a cutting device. The present invention relates to an automatic size change method in a cutting device that automatically changes the cutting angle during cutting to efficiently perform cutting work.

[Prior art]

Conventionally, during cutting work on coating materials such as tire constituent materials,
During cutting or when changing the cutting angle, etc., setup changes as shown in the flowchart of FIG. 5 have been performed.

In other words, the material to be cut that is conveyed by the conveyor,
If the cutting device is cutting to a predetermined cutting width and cutting angle (A-■), and the cutting width and cutting angle are to be changed midway through, the drive motor of the cutting device and the transport conveyor should be changed. The worker stops the motor (A-
■) Then, the worker visually rotates the cutting device to a desired angle to adjust the cutting angle (A-■)0 Next, the worker starts the drive motor of the conveyor and When the leading end of the material passes through the cutting device for a predetermined length, the conveyor is stopped (A-■).

Then, the end portion of the material to be cut is cut using a cutting device (
A-■) and remove the cut end portion (A-
■).

In this situation, the worker sets the cutting device and the stop detector (phototube, etc.) of the conveyor to the predetermined position while looking at the conversion table (A-■), and then performs the setup change work as described above. After the process is completed, the automatic switch is restarted (A-■), and the material to be cut is cut at a predetermined cutting angle and at a predetermined cutting angle.

However, in the conventional cutting work as described above, the work during cutting and changing the cutting angle were all done manually, which required a lot of effort and time, and also required visual inspection, worker's impression, etc. Since the settings were made according to the following rules, there were problems in that setting errors occurred and the cutting and cutting angles could not be set accurately.

(Object of the Invention) This invention was devised by focusing on the conventional problems, and its purpose is to control the feed motor and angle control motor of the cutting device by setting predetermined data in advance. By automatically performing based on the commands of the control device,
Automatic cutting equipment that does not require a lot of effort and time during setup changeovers, and also allows accurate and efficient cutting by always setting the cutting angle while cutting the material to be cut. This provides a method for resizing.

[Structure of the invention]

In order to achieve the above object, the present invention cuts a material to be cut by a predetermined length by a transport conveyor using a cutting device that is movable in the transport direction of the transport conveyor and whose cutting angle is adjustable. An automatic size changing method in a cutting device that cuts at medium and cutting angles, the control device controlling the feed motor and the angle control motor of the cutting device being adapted to the cutting angle in advance while cutting the material to be cut. The main purpose of this invention is to set the data and drive each motor according to commands from the control device when changing the setup of the material to be cut, and to perform cutting work by automatically changing the cutting angle while cutting the material to be cut. That is.

(Example of the invention) The present invention will be described in detail below based on the accompanying drawings.

1 and 2 show a plan view and a front view of a cutting device embodying the present invention, in which the cutting device 1 is supported on a rail 2 via a cart 3. FIG.

The trolley 3 moves on the base 2 via wheels 5 to cut the material W.
The drive device for this truck 3 is a nut fixed to the bottom of the truck 3, and a pole screw 7 is connected to a feed motor 6 installed on the base 2. 8 and is configured to be driven by being screwed into it. Note that 9 is a detector that detects the number of rotations of the feed motor 6 using pulses or the like.

The cutting device 1 supported on the rail 2 cuts the workpiece W.
The guide member 10 is vertically movably installed along a guide member 10 installed in the width direction H of the guide member 10, and the guide member 10 is supported so as to be able to pivot around a fulcrum 0. One end of a pole screw 12 is fitted into one end of the guide member 10 that supports the cutting device 1 through a nut 11, and this pole screw 12 is connected to the carriage 3 through a universal joint 13.
It is connected to an angle control motor 14 with a brake installed above.

In addition, a conveyor 15 disposed at the bottom of the cutting device 1
A detector 16 (linear scale) for detecting the angle of the cutting device 1 is installed at the center in the zero width direction.

The feed motor 6 of the cutting device 1 and the angle control motor 14
is connected to a control device (computer) not shown,
The cutting depth and the cutting angle α at the time of changing the setup of the material to be cut W are set in advance in this control device.

Next, a method for automatically changing the size of the workpiece W is shown in Fig. 3 (a).
) to FIG. 3(e) and the flowcharts in FIG. 4 will be described.

First, as shown in FIG. 3(a), a conveyor (not shown) sends out the workpiece W at a constant speed, and the cutting device 1 cuts the workpiece W at a constant width and at a constant cutting angle α. State of repeated automatic cutting (B in Figure 4)
-■), when the start button for setup change of the control device is pressed (B-■ in Fig. 4), the feed motor 6 of the cutting device 1 and the angle control The motor 14 operates at the same time, the tip of the material to be cut W is sent out by a predetermined length l, and the cutting device 1 is rotated by a predetermined angle α (in Fig. 3 and Fig. 3(C)).
.

Here, if the cutting angle α is the same, when the start button for setup change is pressed, the answer is YES and the material to be cut W is sent out again at a constant speed by the conveyor, and the material to be cut is cut by the cutting device 1. Automatic cutting is performed repeatedly at a constant width of W and at a constant cutting angle α (fourth
B-■ in the figure), and in the case of NO, change the cutting angle α as described above (B-■ in Figure 4) and send out a predetermined length by the conveyor 15 according to the command from the control device. is performed (B-■ in FIG. 4).

In this way, once the setup change work for the material to be cut W is completed, as shown in FIG. The end cutting portion Wa at the tip of the W is cut and removed (B-■ in Fig. 4), and after this, the material to be cut W is sequentially sent out with a predetermined length l' by the conveyor 15, and The cutting material W is continuously cut at a width h' and at a predetermined angle α'.

Further, even when setup change is to be performed after this, the same method as described above is used.

〔Effect of the invention〕

This invention uses a cutting device that is movable in the transport direction of the transport conveyor and whose cutting angle is adjustable to cut the material that has been sent out a predetermined length by the transport conveyor as described above. An automatic size change method in a cutting device that cuts at a cutting angle, the control device controlling a feed motor and an angle control motor of the cutting device being supplied with data corresponding to the cutting angle in advance while cutting a material to be cut. The motors are driven by commands from the control device when changing the setup of the material to be cut, and the cutting angle is automatically changed during the cutting of the material to be cut. It does not require a lot of effort and time during replacement work, and it can significantly shorten the setup change time.Therefore, it can reduce the labor of setup change work, and even beginners can easily perform setup change work. Since the setup work is performed by a control device, there are few mistakes during cutting and in setting the cutting angle, and therefore, the cutting angle can be surely set during cutting, and cutting work with high precision can always be efficiently performed.
