Abstract

PURPOSE:To surely detect abnormality even in the case that either one sheet of packages in the combination is wrong among n sheets of packages. CONSTITUTION:Signal lines 41-4m to show the type of object are wired on a backboard 20, between each package 11-1n, and only the applicable signal line 51 is wired for respective packages 11-1n, and the signal line of only one sheet of package 11 is earthed inside a package. In the case that the packages 11-1n are mounted in normal combination, a monitor package 30 detects the earth condition. In the case that the combination of the packages 11-1n is different, all signal lines 41-4m get in open condition, and the monitor package 30 detects this.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package mounting abnormality detecting apparatus for detecting a package mounting abnormality in a unit constituted by mounting a plurality of packages on a backboard according to the type of article.

[0002]

2. Description of the Related Art Conventionally, in this type of unit, package mounting abnormality detection has been performed by the method shown in FIG.

In this system, n is placed on the backboard 20.
The package 11 to 1n and the monitoring package 30 are mounted, and the signal line 40 indicating the product type is connected between one of the packages 11 to 1n, for example, the package 1n and the monitoring package 30, and the signal line The signal output from the package 1n through 40 is received by the monitoring package 30, and thereby the type of the package 1n is recognized.

[0004]

As described above, the conventional package mounting abnormality detection is performed using the n packages 11
Since the signal line 40 indicating the paper type is connected to only one of the packages 1n to 1n for monitoring, the other packages 11 to 1 (n-1) are not monitored. Therefore, these packages 11-1
When the mounting state of (n-1) is abnormal, there is a problem that this cannot be detected.

The present invention has been made in view of the above problems, and an object thereof is to reliably detect an abnormality in the mounting state of any one of a plurality of packages. It is to provide a package mounting abnormality detection device capable of performing the above.

[0006]

A package mounting abnormality detecting device of the present invention has a plurality of package mounting parts on a backboard, and a plurality of packages are mounted on each of these package mounting parts according to the type of product. A plurality of first signal lines arranged according to the product type between the plurality of package mounting portions on the backboard, and the plurality of packages corresponding to the product type And a second signal line grounding means for grounding the second signal line of the package mounted on the package mounting portion on one end side of the plurality of packages, and the backboard. The package is disposed on the upper side and monitors the ground state of the package at the end through the first signal line and the second signal line, and when the ground state is detected, all the packages are detected. Implementation determines that normal, in which a monitoring package mounting of at least one package is determined to be abnormal when it detects an open state.

In this package mounting abnormality detecting apparatus, when a proper package is mounted on each of the package mounting portions on the backboard according to the product type, the first signal line and the Second
The ground state is detected through the signal line of. On the other hand, when a different package is mounted on any one of the package mounting units, the monitoring package detects the open state and determines that the mounting is abnormal.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

1 to 4 show a concrete structure of a package mounting abnormality detecting apparatus according to an embodiment of the present invention. Here, FIG. 3 shows the structure of the backboard 20, and FIG.
Represents the configuration of the packages 11 to 1n. In addition, in the present embodiment, the same components as those in FIG.

On the backboard 30, n package mounting portions 21 to 2n are formed, and the monitoring package 30 is mounted adjacent to the package mounting portion 2n located at the right end in the figure. Between the package mounting portions 21 to 2n and between the package mounting portion 2n and the monitoring package 30, m signal lines (first signal lines) 41 to 4m indicating the product type are formed. These signal lines 41 to 4m are package 11 to 1n, respectively.
It is formed corresponding to the product type determined by the combination of. The monitoring package 30 has these signal lines 41 to 4 m.
Is to detect the output state of and to determine whether the mounting state is normal or abnormal according to the output state.

The packages 11 to 1n are mounted so as to correspond to the package mounting portions 21 to 2n provided on the backhoe 20, respectively. Each of these packages 11 to 1n has a signal line 51 depending on the type of product.
Is wired. In this embodiment, the backboard 20
Only the signal line corresponding to the product type corresponding to the signal line 41 on the side is wired. In addition, these packages 11 to 1
Among n, only the signal line 51 formed on the package 11 mounted on the package mounting portion 21 is grounded in the package.

FIG. 1 shows a state in which the packages 11 to 1n are properly mounted on the corresponding package mounting portions 21 to 2n. In this state, the monitoring package 30
Receives signals from m signal lines 41 to 4m. In this case, the packages 11 to 1n are mounted in a normal combination, and the signal line 51 of the package 11 is grounded. Therefore, the monitoring package 30 includes the signal lines 51 of all the packages 11 to 1n and the backboard 20. The grounding state is detected through the signal line 41 corresponding to the item type, and the packaging of the packages 11 to 1n is determined to be normal.

Here, as shown in FIG. 2, if a package 62 corresponding to a different product type from the above is erroneously mounted on the package mounting portion 22, for example, the signal line 52 of the package 62 is mounted. Will be connected to the signal line 42 on the backboard 20. In this case, since the other packages 11 and 13 to 1n are respectively connected to the signal line 41, the monitoring package 30 includes all the signal lines 4
Detecting that each of 1 to 4 m is in the open state, it is determined that the mounting is abnormal. This is also the case when packages corresponding to different product types are mounted in other package mounting units.

As described above, the package mounting abnormality detecting apparatus of the present embodiment can reliably detect the mounting abnormality when any one or more packages are erroneously mounted.

[0015]

As described above, according to the package mounting abnormality detecting device of the present invention, a plurality of package mounting portions are provided on the backboard, and each of these package mounting portions has a plurality of package mounting portions depending on the type of the article. In a unit configured by mounting a package, a plurality of first signal lines arranged according to the type of a product between a plurality of package mounting parts on the backboard, and a product for each of the plurality of packages. A second signal line provided corresponding to the type, and a second signal line grounding means for grounding the second signal line of the package mounted on the package mounting portion on one end side of the plurality of packages, It is arranged on the backboard and monitors the ground state of the package at the end through the first signal line and the second signal line, and when the ground state is detected, all A monitoring package is provided which judges that the package mounting is normal and judges that the mounting of at least one package is abnormal when an open state is detected. Therefore, any one of the plurality of packages is mounted. Even if there is an abnormality in the state, there is an effect that the abnormality can be surely detected.
