Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention provides a visual inspection of a package produced in a spinning factory to identify the machine number and the weight number of the winder that produced the defective package.
The present invention relates to a package inspection system capable of facilitating maintenance and management of winders.

[0002]

2. Description of the Related Art A package produced by an automatic winder may be inspected because it may have no bunch, twill drop, step winding, chrysanthemum winding or the like with bad appearance or abnormal weight. The device performs a visual and weight inspection. Then, as a result of the inspection, the normal packages are sent to the stocker and packed, but all the defective packages are guided to the same defective line and automatically removed.

[0003]

However, there is a package (hereinafter, referred to as a quasi-normal package) that can be regarded as normal by the operator's visual judgment even if the package is judged to be defective by the above inspection apparatus. A typical example is a package (no bunch) in which the paper tube is not bunched. In some cases, the operator can make a normal package by bunch winding. Further, with regard to twill drop, step winding, chrysanthemum winding, etc., even if the inspection device determines that they are defective, they can be regarded as normal depending on the degree of the defect. It is uneconomical to uniformly process such a quasi-normal package while mixing it with other defective packages.

Therefore, an object of the present invention is to provide a package inspection system which distinguishes a quasi-normal package which can be regarded as normal by an operator's visual judgment from other defective packages and treats them separately.

[0005]

In order to achieve the above object, the package inspection system of the present invention is designed to inspect a package on the way of a conveyor which circulates and conveys a package from a winder on a numbered tray. The inspection device, the defective package dispensing unit, and the good package dispensing unit are provided. When the inspection result of the testing device is the defective package, the defective package dispensing unit dispenses the tray of the corresponding package by visual check. It is configured to distinguish between a line for flowing various packages and a line for flowing packages that can be regarded as normal by visual check.

[0006]

[Operation] The inspection items of the inspection device are (1) no bunch, (2) twill drop (small diameter, large diameter), (3) step winding (small diameter, large diameter), (4) chrysanthemum, (5) Abnormal weight (out of scale), (6) Black light, (7) Inner layer defect, etc. "No bunch"
The so-called bunch winding, which winds the thread end around the paper core for the purpose of tapping, is not performed. "Twill drop" means that the thread end falls on the end face of the package, and "column winding" means the package. The winding shape viewed from the end surface of is a stepped shape, and the "Kiku winding" is a winding shape viewed from the end surface of the package in a chrysanthemum shape. In addition, (6) “Black light” means that different types of yarn are mixed in the yarn, and when UV rays are applied, a stripe pattern is visible due to the difference in reflectance, which is inconvenient for knitting and weaving. is there. Furthermore, "Inner layer failure" in (7) above
Is a yarn cutting characteristic in which the yarn clearer of the winder 1 performs the yarn cutting operation with the length and the thickness of the yarn defect (Fig. 4).
In the case of (2), if there are many yarn defects outside the yarn cutting curve C, the yarn quality is close to the boundary of the yarn cutting curve C and the yarn quality is not very good.

These are judged to be defective by the inspection device, but of these, "no bunch", "twill drop", "step winding"
Regarding the appearance defect of "Kikumaki", the quality can be judged even by the naked eye of the operator. Therefore, even if the package is judged to be defective by the inspection device,
A package that can be regarded as normal by the operator's visual judgment (quasi-normal package) is processed separately from other defective packages whose visual judgment is not good or bad, thereby eliminating waste such as rewinding. Therefore, the production efficiency can be improved. Here, the defective line may be "no bunch", "twill drop", "step winding" and "chrysanthemum winding" as one line, and may be a total of two lines including other defective lines, or "no bunch". It can be divided into two lines, "twill-falling", "step winding", and "chrysanthemum winding", and a total of 3 lines can be added together with other defective lines.

[0008]

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1, a plurality of automatic winders 1 each having a plurality of weights arranged in parallel are installed in a spinning factory, and each machine base is provided with a package 2 which is hoisted from each weight. A conveyor 5 is provided at one end of the table to carry it out. Then, the package 2 carried out by the conveyor 5 is carried to the inspection station 4 via the overhead conveyor 3. The overhead conveyor 3 is mainly composed of a track 6 which is installed in a closed loop, and a hanger 7 which is provided along the track 6 so as to be movable by chain drive. An unloading device 8 for unloading the package 2 onto the hanger 7 is installed at the conveyor 5 unloading end of each winder 1, and an unloading device 9 for unloading the package 2 from the hanger 7 is installed at the inspection station 4. is set up.

As shown in FIG. 2, the hanger 7 is constructed by mounting an arm 11 for mounting the package 2 on a support substrate 10 which is hung from a chain (not shown), and receives the package 2 from the unloading device 8. The package 2 can be easily delivered to the unloading device 9.

A magnetic recording medium 12 capable of writing and erasing information is attached to a supporting substrate 10 of the hanger 7, and information from the winder 1 above the unloading device 8, that is, the machine base of the winder that has produced the package 2 concerned. A writing device 13 is provided for writing the information of the number and the weight number and the inner layer defect information (escort data) on the recording medium 12. A reading device 14 for reading the escort data recorded on the recording medium 12 is provided above the unloading device 9.

On the other hand, the inspection station 4 is provided with a closed-loop tray conveyor 16 for circulating and transporting the packages 2 individually on the trays 15.
In the middle of 6, there is provided an inspection device 17 for inspecting the appearance and weight of the package conveyed together with the machine number and weight number information of the manufacturer and the inner layer defect information. The inspection device 17 includes a package appearance measuring device using a CCD camera that images the appearance of the package and a weight measuring device that measures the weight of the package (not shown). Among them, the package appearance measuring instrument irradiates strip light obtained by passing light from a light source through a slit having a width of about 1 mm from the side surface to the end surface of the package, and the edge shape (shape of the side surface and end surface) of the irradiated portion An image is captured by a CCD camera from one side, and an image processed by a computer is processed to evaluate the image displayed on the monitor. From the detection signals of the package appearance measuring device and the weight measuring device, the arithmetic unit including the sequencer determines whether or not the package is a defective package (S1 in FIG. 3). The computer 21 determines the item (S2 in FIG. 3). The computer 21 also stores and totals the defective items of this defective package in association with the above information. As a result, the machine number and the weight number of the winder that has produced the defective package can be easily traced and checked, and the failure content of the winder can be inferred and diagnosed from the defective item.

The inspection items performed by the inspection device 17 as a whole include (1) no bunch, (2) twill drop (small diameter, large diameter), (3) step winding (small diameter, large diameter), (4) Kikumaki, (5) Abnormal weight (out of range), (6) Black light, (7) Inner layer defect, etc.

The computer 21 judges the quality of the package with respect to these inspection items. For no bunch, twill drop, step winding, and chrysanthemum winding, a weight error is detected by a detection signal from a package appearance measuring device using a CCD camera. The detection signal from the weight measuring device is used. But,
Regarding the inner layer defect, the computer 21 receives the inner layer defect information of the escort data and determines whether the inner layer is defective or not, not by the detection signal from the package appearance measuring device. Of these, "weight abnormalities", "black light", and "inner layer failure" cannot be judged with the naked eye, but "no bunch", "twill drop", "step winding", and "chrysanthemum winding" can be visually judged. The quality can be judged.

In the tray conveyor 16, the inspection device 1
A package supply unit (a) for transferring the packages 2 from the unloading device 9 to the tray 15 is provided upstream of 7, and a defective package is delivered to the defective line 18 downstream of the inspection device 17. Package delivery section (b)
A good package payout unit (c) for paying good packages to the stocker 19 is sequentially provided. The tray 15 is formed by projecting a peg for inserting the package 2 on a circular substrate, and a mark such as a metal ring or a bar code for identification is attached on the upper surface of the substrate (not shown). Numbered. Tray 1 in the package supply section (a)
5, a stopper for temporarily stopping 5; a transfer device (not shown) for transferring the package 2 from the unloading device 9 onto the tray 15 which is temporarily stopped; and a tray number reading device for reading the number of the tray 15. 20 are provided.

The escort data of the package 2 read by the reading device 14 above the unloading device 9 and the tray number read by the tray number reading device 20 are input to a computer (host computer) 21. The escort data is stored in the table in association with the tray number. Further, the inspection result by the inspection device 17 and the defective item are shown in FIG.
As shown in (4), it is input to the computer 21 and added to the table in association with the tray number. Further, the computer 21 totalizes these data, for example, on a monthly basis, and outputs the totalization table on a display or a printer.

The tray number reading devices 22 and 23 are provided in the defective package dispensing section (b) and the good package dispensing section (c), respectively.
Further, a package payout device for paying out the package 2 from the tray 15 is provided (not shown), data in the table is searched by the tray number, and a defective package is paid out from the tray to the defective line 18 in the defective package payout section (b). In the good package payout section (C), good packages are paid out from the tray to the stocker conveyor 24. The computer 21 also functions as a controller for delivering the defective package to the defective line and the good package to the stocker.

By the way, even if the package is determined to be defective by the inspection device 17 and is delivered to the defective line 18 from the defective package delivery section (b), the above-mentioned "no bunch", "twill drop", and "step". Regarding "winding" and "chrysanthemum", there is also a package (quasi-normal package) that can be regarded as normal by an operator's visual judgment. It is uneconomical to process such a quasi-normal package without distinguishing it from other defective packages. Therefore, the defective line 18 is classified into three types of defective lines 25, 26, and 27. Bad line 18
Are provided with guides 28 and 29 for allocating defective packages to defective lines 25, 26 and 27, and are controlled by the computer 21.

The first defective line 25 is "weight abnormality".
The package is a defective package due to “black light” and “inner layer defect”, and is for a package whose quality cannot be judged with the naked eye. The second defective line 26 is for a quasi-normal package which is regarded as a defective package because of "no bunch", that is, it has a character that can be returned to a normal package only by an operator manually performing a mouthpiece process. The third defective line 27 is a quasi-normal package which is regarded as a defective package with respect to “twill drop”, “step winding”, and “chrysanthemum winding” and which can be regarded as normal according to the visual judgment of the operator. In this way, the generation of defective packages is minimized by not classifying all of the packages determined to be defective by the inspection device 17 into the same defective line 25, but by distinguishing between quasi-normal packages and other defective packages. It is possible,
The production efficiency can be improved.

Next, the operation of the embodiment will be described.

First, when the hanger 7 arrives above the unloading device 9, the escort data is read by the reading device 14 and input to the computer 21. The package 2 unloaded from the hanger 7 by the unloading device 9 is transferred by the transfer device onto the tray 15 stopped by the stopper, at which time the tray number is read by the tray number reading device 20, and the computer 21 The tray number and escort data are stored together in the table.

The package 2 is transferred by the conveyor 16 while being inserted into the tray 15, and when passing through the inspection device 17, the package 2 is inspected for appearance and weight. Corresponding and stored.

If the package 2 is a good package, the package 2 passes through the defective package dispensing section (b),
Good package delivery department (C). Then, the tray number is read again by the tray number reading device 23, the data in the table is searched from the tray number, and when the package is a good package, the tray 15 is delivered to the stocker conveyor 24 by the delivery device.

On the other hand, when the package 2 is a defective package, the tray number is read by the tray number reading device 22 when the defective package delivery section (B) is reached, and the inspection result in the table is read by the tray number. To be searched. Since the search result is a defective package, the defective line 18 is transferred from the tray 15 by the dispensing device.
Paid out to. When the defective package is delivered to the defective line 18, the computer 21 controls the guides 28 and 29 to select one of the defective lines 25, 26 and 27 based on the defective item.

In this case, the package 2 is carried to the inspection device 17 together with the machine number and weight number information of the manufacturer 1 and the inner layer defect information, and the inspection result by the inspection device 17 is associated with the above information. Since the computer 21 stores and tabulates the numbers, the machine number and the weight number of the winder 1 that has produced the defective package can be easily traced, and the winder 1 can be checked from the defective item.
Can be inferred whether or not is running well.

Among these defective packages, the defective packages due to “weight abnormality”, “black light”, and “inner layer defect” cannot be judged with the naked eye. It is sent to the defective line 25.
However, for the quasi-normal package that has been determined as a defective package due to “no bunch”, this is sorted into the second defective line 26. If it is determined that the inspection result is not the state of “no bunch” but the abnormal appearance of the package winding such as “twill drop”, “step winding”, and “chrysanthemum winding”, the third defective line 27 is selected.

[0027]

In summary, according to the present invention, a quasi-normal package that can be visually regarded as normal is distinguished from other defective packages without guiding all the packages judged to be defective by the inspection device to the same defective line. The generation of defective packages can be minimized, and the production efficiency can be improved.
