Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a die plate discriminating method and apparatus for a rubber extruder.

[0002]

2. Description of the Related Art Generally, when a rubber extruder is used, a die plate having a corresponding extrusion size is selected from a plurality of die plates prepared for each extrusion size, and the die plate is used as a rubber extruder. Installation work is performed.

[0003] And conventionally, to choose a die plate,
Whether or not the die plate information (displaying numbers and letters, etc.) for each extrusion size provided on the die plate is read visually and collated with the die plate information to be used, and whether they match Was determined.

[0004]

However, as described above,
Since the die plate information is a series of numbers and English letters and is easily mistaken, it takes time to read and collate, and it is impossible to completely prevent reading mistakes and collation mistakes.

Therefore, there is a problem that the die plate is erroneously attached to the rubber extruder and the line is started as it is, resulting in a defective product.

Therefore, the present invention solves the above-mentioned problems of the prior art, and makes it possible to make a pass / fail determination of a die plate in a short time without a reading error or a collation error of die plate information. It is an object to provide a method and an apparatus thereof.

[0007]

In order to achieve the above object, a method for discriminating a die plate for a rubber extruder is such that an identifying bar code is attached to a part of the die plate in advance and the identifying bar code is used. The die plate information is detected by the reading sensor, and then the discriminating means detects the die plate information,
The die plate information to be extruded, which is set and input in advance, is collated to determine whether or not they match, and the determination result is output by the determination result notifying means.

The rubber extruder die plate discrimination device inputs an identification bar code provided on the die plate, a reading sensor for detecting die plate information of the bar code, and die plate information to be extruded. Setting input means, discrimination means for collating and discriminating the die plate information inputted by the setting input means with the die plate information sent from the reading sensor, and a discrimination result for outputting an abnormal signal from the discrimination means. And a notification means.

[0009]

[Operation] Since the reading sensor reads the die plate information by the bar code of the die plate and the discriminating means automatically verifies whether the die plate is correct or not, there is no reading error or collation error, and it is short. It can be determined by time. As a result, it is possible to eliminate the occurrence of defective products due to incorrect mounting of the die plate.

[0010]

The present invention will be described in detail below with reference to the drawings showing the embodiments.

FIG. 1 shows a simplified overall configuration diagram of an embodiment of a rubber extruder die plate discrimination device, and FIG. 2 shows an example of a rubber extruder die plate 1.

The die plate 1 is used by being attached to a rubber extruder. Depending on the size of rubber extruded, the die plate 1 is used.
Therefore, a plurality of die plates 1 for each extrusion size are prepared.

Reference numeral 2 is an identification bar code for displaying die plate information corresponding to the above-mentioned extrusion size, which is composed of, for example, numbers representing sizes, types, etc., and a plurality of bar codes are arranged side by side in the longitudinal direction. It

The bar code 2 is obtained by printing the bar code 2 on the surface of a sheet made of, for example, paper or tetron, and then coating a transparent protective layer made of polyester on the back surface of the sheet. It is attached to the bottom surface of the concave groove 3 of the plate 1 and provided on the die plate 1.

Reference numeral 4 is a reading sensor for detecting the die plate information of the bar code 2, and the detected die plate information is
It is sent to the determination means 5. As the reading sensor 4, for example, an ordinary commercially available bar code reader or the like that optically detects the bar code 2 to read various information is used.

Reference numeral 6 is die plate information of the die plate to be extruded (die plate information of the die plate 1 to be used for extruding).
With the setting inputting means for inputting to the discriminating means 5, for example, die plate information corresponding to a predetermined extrusion size can be selected and input to the discriminating means 5 from a plurality of die plate information set and stored in advance by a computer or the like. .

The discriminating means 5 comprises a comparison circuit and the like, and discriminates and discriminates the die plate information input by the setting input means 6 and the die plate information sent from the reading sensor 4.

Reference numeral 7 is a discrimination result notifying means for outputting an abnormality signal or the like from the discrimination means 5, which can inform the abnormality (or whether it is normal) by a buzzer or a light.

Thus, with the die plate 1 attached to the rubber extruder, the bar code 2 can be automatically read by the reading sensor 4, for example, by driving the fluid cylinder 8 as shown in FIG. A sensor advancing / retreating means having a supporting member 10 slidable along the guide rails 9 is provided in the vicinity of the die plate mounting portion of the rubber extruder, and the reading sensor 4 is attached to the tip of the supporting member 10.

Further, the fluid cylinder 8 is driven by a discrimination start signal sent by a switch operation or the like, and the reading sensor 4 is attached to the die plate 1 attached to the rubber extruder.
The barcode 2 is moved forward, and when it reaches a readable position, it automatically stops, and the die plate information of the barcode 2 is detected.

Next, a method for discriminating the die plate for the rubber extruder will be described.

First, the die plate 1 to be used for extrusion is selected from the plurality of die plates 1 and attached to the rubber extruder. At this time, the reading sensor 4 is retracted by the sensor advancing / retreating means shown in FIG. 3 so as not to interfere with the work until the die plate 1 is attached.

After the mounting work of the die plate 1 is completed,
When the discrimination start signal is sent by a switch operation or the like, the reading sensor 4 detects the die plate information of the bar code 2 of the die plate 1.

The die plate information detected by the reading sensor 4 is sent to the discriminating means 5 and collated with the die plate information to be extruded which is preset and inputted, and it is discriminated whether or not they coincide with each other.

The discrimination result of the discriminating means 5 is output by the discrimination result notifying means 7 as an abnormal signature or an OK signature. If there is an abnormal sign ── flashing light or a buzzer sign, replace the die plate 1. In this way, an accurate pass / fail judgment of the die plate 1 can be automatically made before the start of the line.

[0026]

Since the present invention is constructed as described above, it has the following great effects.

The reading sensor 4 reads the die plate information of the bar code 2 of the die plate 1, and the discriminating means 5 reads it.
Since the die plate 1 attached to the rubber extruder automatically determines whether or not there is any mistake, it is possible to make a determination in a short time without a reading error or a verification error. As a result, it is possible to eliminate the occurrence of defective products due to a wrong mounting of the die plate 1.
