Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a quantity inspection device for inspecting a unit load of a plurality of articles stacked on a pallet.

[0002]

[Prior art]

 As a conventional technique relating to the inspection device, one disclosed in Japanese Patent Laid-Open No. 55-18202 is known.

The conventional technique described in the above publication will be described. In Japanese Patent Laid-Open No. 55-18202, a plurality of switches are arranged corresponding to different panel shapes to be transported, and these switches are described. There is described a panel article type reader configured to obtain a detection signal based on an on / off operation and determine the shape of the panel to be conveyed based on the difference in the detection signal.

[0004]

[Problems to be solved by the device]

 However, the above conventional technique has the following problems.

That is, the panel type reading device described in Japanese Patent Laid-Open No. 55-18202 cannot inspect the quantity.

[0006] Therefore, an object of the present invention is to provide a quantity inspection device capable of inspecting the loading quantity of a unit load in which a plurality of articles are stacked on a pallet.

[0007]

[Means for Solving the Problems]

 The present invention is a height detection device for detecting a stacking height of a unit load in which a plurality of articles are stacked on a pallet, and a code reading device for detecting a product code or the like displayed on the product. The above-mentioned object is achieved by providing a quantity inspection device characterized by comprising a computing device for computing a loading quantity based on the loading height and the product code and the like.

[0008]

[Action]

 The quantity inspection device of the present invention is capable of inspecting a unit load of a plurality of articles stacked on a pallet.

【Example】

 An embodiment of the quantity inspection device of the present invention will be described below.

FIG. 1 is a block diagram showing a configuration of an embodiment of the quantity inspection device of the present invention, and FIG. 2 is a layout view of photoelectric switches of the quantity inspection device shown in FIG.

In these drawings, (1) is a height detection device for detecting the stacking height of a unit load (U) formed by stacking a plurality of articles (G) on a pallet (P), A plurality of (for example, 12) photoelectric switches (PH1), ... (PH12) arranged in the vertical direction are provided. Further, (2) is a code reading device for detecting the product code or the like displayed on the article (G), which is the product code (JAN) or the distribution symbol code (ITF) printed on the case of the article (G). A bar code reader (21) for reading is provided. Further, (3) is a computing device (upper CPU) that computes the quantity to be loaded based on the above-mentioned loading height and the above-mentioned product code, etc. It has data on the quantity of articles (G) to be stored and which photoelectric switch (PHI), ..., (PH12) operates according to the number of stacked stages. The photoelectric switches (PH1), ..., (PH12) may be arranged at appropriate intervals according to the height range of the article (G) to be inspected.

Next, a quantity inspection operation by the above-described quantity inspection device will be described.

The articles (G) are unit-loaded (U) by being stacked on the pallet (P) in units of stages in a predetermined pattern for each product type, and the articles are unit-loaded (U) -ized. (G) is placed on a pallet transfer conveyor (not shown) by a forklift, and the unit load (U) supplied on the pallet transfer conveyor is any photoelectric switch (PH1) of the height detection device (1), The stacking height is detected depending on whether (PH12) detects the product (G). The bar code reader (21) reads the product code (JAN) or the physical distribution symbol code (ITF) printed on the case of the article (G), and the product (G) forming the unit load (U) is read. The variety is detected.

The stacking height and the type are detected. For example, the photoelectric switch (PH1) to photoelectric switch (PH5) detect the article (G), and the photoelectric switch (PH6) to the photoelectric switch (PH12) detect the article ( If G) is not detected, it is detected that the articles (G) are stacked on the pallet (P) in five stages to form a unit load (U). If the photoelectric switch (PH1) to the photoelectric switch (PH8) detect the article (G) and the photoelectric switch (PH9) to the photoelectric switch (PH12) do not detect the article (G), the article (G). It is detected that 6 units are stacked on the pallet (P) to form a unit load (U). Thus, the number of articles (G) forming the unit load (U) is inspected based on the detected number of articles and the quantity data of articles (G) to be loaded per one article. .

The embodiments of the quantity inspection device of the present invention have been described above, but the present invention is not limited to these. For example, instead of a plurality of photoelectric switches (PH1), ... (PH12) arranged in the vertical direction, a distance measuring device having a laser light source and an image sensor camera is arranged above the pallet conveyor. It may be arranged to detect the loading height of the unit load (U).

[0016]

As described above, the quantity inspection device of the present invention is capable of inspecting the quantity of a unit load in which a plurality of articles are stacked on a pallet.
