Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a package inspection device for inspecting whether a package formed by an automatic winder is properly formed.

[0002]

[Prior art]

 The package formed in the automatic winder is inspected whether or not a predetermined package is properly formed. As one of the methods, each part of the package outer periphery is photographed with an image receiver, image processing is performed on it, and it is judged whether or not it is within an allowable range with respect to predetermined image information that has been input in advance. Out-of-range packages are being rejected as defective packages. As a result, we have eliminated packages that have the top and bottom edges of the package being traversed, those that have step winding or chrysanthemum winding, and those that are mixed with different types of products. A package inspection device is placed on the top.

In such a package inspection device, the status of various places such as the upper end surface and the lower end surface of the package, the side surface, and the end surface and the edge portion of the side surface are received by the image receiver or the reflected light of the emitted laser light. Since many optical receivers, etc. are used, and optical strict environmental conditions are required, it is desirable that the room be a closed room that does not let in light from other sources. Therefore, the package inspection device is provided with doors at the entrance and exit of the conveyor line, and the door is opened and closed each time one package is loaded or unloaded.

[0004]

[Problems to be solved by the device]

 In the above-mentioned conventional package inspection device, a gannon door is used as a door provided at the entrance and the exit of the package. Therefore, a space for opening and closing the door is required at the entrance and the exit, and the packages on the conveyor line cannot be narrowed in the front and back, which reduces the conveyor efficiency. Therefore, the package inspection time becomes long.

As a countermeasure, it is conceivable to provide a conveyor near the door, which has a higher transport speed than a normal conveyor line, but this requires a large amount of equipment cost. In addition, the Kannon door requires a mechanism that opens and closes the left and right doors in synchronization, and this has the drawback of further increasing equipment costs.The Kannon door must be completely sealed at the joint between the left and right doors. However, if the sealed state is incomplete, light leaks in the direction of the height of the entire door, and there is a drawback that the image receivers and light receivers installed at various locations will often malfunction. .

Therefore, an object of the present invention is to configure a door with a simple and inexpensive facility, ensure a tight seal, prevent the inspection device from malfunctioning, and improve the inspection speed.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a package inspection device for loading and unloading a package conveyed by a conveyor, and inspecting the package by an optical device. It is equipped with a door to open.

[0008]

[Action]

 Since the present invention is configured as described above, when the package is loaded into the package inspection apparatus, the door of the carry-in port is opened upward, the package is taken in, and the door is closed again. Further, when carrying out the package after the inspection from the package inspection device, the door of the carry-out port is opened upward, the package is carried out to the outside, and the door is closed again.
