Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for inspecting a processed food wrapper, and more particularly, to a method and an apparatus for inspecting a transcription error of a part transferred to the surface of a food wrapper.

In general, various food processing technologies have been developed due to the development of industrial technology, and various processed foods have been developed. Processed food refers to foods that are processed with natural food ingredients such as agricultural products, livestock products, aquatic products, etc. as they are or with additives, which are easily digested and absorbed and stored for a long time. Various types of processed foods including snacks, biscuits, and chocolates, as well as noodles including confectionery, ramen and spaghetti, as well as breads, coffee, instant food, and the like are currently being developed and marketed.

These processed foods are produced in large quantities in a food processing factory through a series of processing steps, and are then packaged in a single wrapper or packaging container sterilized by a sanitary facility so as not to deteriorate the processed food during the distribution period Hereinafter, referred to as "wrapping paper").

In addition, the processed food is transferred to the outer surface of the wrapping paper, which is part of various information, such as the manufacturing factory, the manufacturing date, the expiration date, and the like of the processed food. Transcription, which is part of the packaging of processed foods, is strictly regulated by the Food Control Act, and sanctions are imposed when a part of the person is missing, damaged, or in error. Therefore, in the process of packaging the processed food, the defect of the package itself is checked together with the defect of the part transferred to the wrapping paper.

1 is a block diagram schematically showing a processed food packaging system according to the prior art. As shown in the figure, the processed food packaging system comprises a supply part 11 for supplying a wrapping paper and a ribbon, a transfer part 12 for transferring a part of the wrapping paper, a wrapping paper inspection part 13 for inspecting a part of the wrapping paper, A processed food packaging section 14 for packaging the processed food with respect to the wrapping paper to which a part of the package is normally transferred, and a product shipping section 15 for shipping the wrapped product. In such a packaging system, the process of transferring and inspecting a part of a person may be applied before or after the process of packaging the processed food.

The transferring process of a part of the wrapping paper transferring unit 12 is carried out by transferring a part of a person from a ribbon to a wrapping paper by using a ribbon and a wrapping paper for transferring a part of the ribbon and a wrapping paper into a transferring device. The process of inspecting the error of the transferring part, which is a part of the wrapping paper inspecting part 13, comprises passing the wrapping paper having passed through the inspecting device and inspecting whether a part of the inserting part is correctly transferred to the image taken via the vision camera. At this time, the operator checks the image provided through the display device directly with the naked eye and checks the transfer error. Therefore, the transfer error inspection, which is a part of the conventional art, requires a worker to check whether there is an error with the naked eye, so that the workability is lowered and the accuracy of the work is lowered.

To prevent this, an apparatus for automatically detecting a transcription error of a part of a person by analyzing an image taken by a camera has been disclosed in Japanese Patent Application Laid-Open No. 2000-109033 and Korean Utility Model No. 20-2013-0000677.

The transfer error inspection apparatus of the preceding documents has a problem that the accuracy of the inspection is deteriorated because the inspection target is only a part of the sealed package. That is, since the inspection is performed on the wrapping paper passing through the quick process, if an instantaneous malfunction of the apparatus or the program occurs, the inspection may not be performed and the inspection may be performed. Particularly, since the wrapping paper after the processed food is packaged has a three-dimensional shape due to the contents, there is a problem that errors often occur in the inspection itself.

In addition, if the defective transfer package can not be immediately collected, the conventional defective error inspection device is inspected in units of individual packages, and then shipped to the product after packaging the processed food. After the product is shipped, There is a problem that it becomes difficult to find. In this case, there is a problem that all the products produced in the same process are re-inspected by the naked eye or all products are discarded in the wick at the product production factory.

In addition, if a transcription error occurs in a specific packaging during the transcription process, which is a part of the processed food packaging, there is a high possibility that a transcription error occurs in the other packaging adjacent to the packaging. This is because transcription errors are problematic in the transcription process or there is a problem with the transcription ribbon, and the same problem may exist in the adjacent wrapping paper. However, the conventional error detection apparatus according to the related art has a disadvantage in that the accuracy of the inspection is degraded because only the corresponding package is collected according to the inspection result on a single package.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a block diagram schematically showing a processed food packaging system according to an embodiment of the present invention, and FIG. 3 is a flowchart illustrating a process of inspecting a wrapping paper transfer error according to an embodiment of the present invention.

2, a processed food packaging system according to the present invention includes a packaging sheet supply unit 101 for supplying a packaging sheet, a ribbon supply unit 102 for supplying a partially printed ribbon, A wrapping paper inspecting section 105 for inspecting a transfer error which is a part of the wrapping paper to be inspected, and a copying section inspecting section 105 for inspecting the transferring part, which is a part of the wrapping paper, A packing unit 107 for packing the processed food into a wrapping paper which is partly transferred, and a shipping unit 108 for shipping the packaged product. Particularly, A waste ribbon feeding unit 201 for feeding back the separated waste ribbons, and a waste ribbon inspection unit 202 for inspecting the waste ribbons for transfer errors. That is, the processed food packaging system of the present invention includes a transfer error detection system for a wrapping paper and a transfer error detection system for a waste ribbon.

Specifically, the transfer unit 103, which is a part of the transfer unit 103, combines the wrapping paper supplied from the wrapping paper supply unit 101 and the ribbon supply unit 102 with the ribbon, and thermally transfers a part of the ribbon from the ribbon to a specific position on the wrapping paper. The waste ribbon separating unit 104 separates the used ribbon from the transferring apparatus and inspects whether the transferring of a part of the wrapping paper is completed . The wrapping paper inspecting unit 105 judges an error by reading the characters transferred and stamped on the surface of the wrapping paper as a reading target. The wrapper inspecting unit 105 for this purpose may include a vision camera and a display unit for inspection.

The alarm unit 106 is configured to notify the operator when a transfer error is detected by the wrapper inspecting unit 105, and may be composed of various kinds of alarm means such as an alarm lamp and an alarm bell. The packaging unit 107 is configured to seal and package the processed food using a well-transferred wrapping paper, which is a part of the packaging unit 107, and can be constituted by a known processed food packaging apparatus. The shipment portion 108 is configured to load and convey the product packed with the processed food, and can be constituted by a known product shipment device.

The waste ribbon feeding unit 201 is configured to supply the waste ribbon collected from the waste ribbon separating unit 104 of the wrapping paper inspecting system to the waste ribbon inspecting unit 202 and is composed of various types of rolls . For example, the waste ribbon supply unit 201 may include a supply roll for supplying waste ribbons from one side and a receiving roll for receiving waste ribbons from the other side.

The waste ribbon inspection unit 202 inspects whether a part of the waste ribbon is partially transferred to the waste ribbon by heat transfer. The closed ribbon inspection unit 202 judges an error by using the thermally-transferred empty character portion as a reading target. The specific configuration of the waste ribbon inspection unit 202 and the transfer error checking process performed thereby will be described later.

As shown in FIG. 3, when the wrapping paper and the transfer ribbon are supplied from the packaging paper supply unit 101 and the transfer ribbon supply unit 102 (S11 and S12), respectively, , A part of the transfer ribbon is transferred to the surface of the wrapping paper at the transferring part 103 (S13). After the part is transferred to the wrapping paper, the waste ribbon separating part 104 separates the part of the waste ribbon from the wrapping paper (S14), and the wrapping paper inspecting part 105 inspects whether the part transferred to the wrapping paper is well transferred S15). If it is determined that an error has occurred in the part of the wrapping paper, the wrapping paper inspecting unit 105 causes the alarm unit 106 to generate an alarm (S16, S17). If it is determined that no error has occurred, Proceed with the examination.

On the other hand, a waste ribbon transferred to a wrapping paper is separated by a waste ribbon separating unit 104, and then a transfer error check is performed on a waste ribbon in a separate waste ribbon inspection apparatus. That is, the waste ribbon feeding unit 201 supplies the waste ribbon to the waste ribbon inspection unit 202 (S21). In the waste ribbon inspection unit 202, it is inspected whether a part of the waste ribbon has been transferred satisfactorily (S22). When it is determined that an error has occurred in the transfer, which is a part of the closed ribbon, the closed ribbon inspection unit 202 causes the alarm unit 106 to generate an alarm (S23, S24). If it is determined that no error has occurred, Proceed to the next part of the ribbon.

As described above, the transcription error checking process, which is a part of the present invention, proceeds to the wrapping paper that has been partially transferred, and at the same time the waste ribbons transferred partly to the wrapping paper are transferred in parallel to improve the accuracy of the transferring error detection.

FIG. 4 is a block diagram showing a waste ribbon inspection apparatus according to an embodiment of the present invention, and FIG. 5 is a flowchart illustrating a transfer error checking process for a waste ribbon according to an embodiment of the present invention. 6 is a view showing an example of a closed ribbon according to an embodiment of the present invention, FIG. 7 is a view showing various examples of errors which are part of the closed ribbon of FIG. 6, and FIG. FIG. 9 is a view showing an example of error reading of the reading unit according to the embodiment of the present invention.

4, a waste ribbon inspection apparatus 100 according to an embodiment of the present invention includes a closed ribbon loading unit 110, a camera unit 120, a display unit 130, a reading unit 140 A setting unit 150, an alarm unit 160, and a control unit 170. As shown in FIG.

Specifically, the closed ribbon loading unit 110 may include a supply roll and a take-off roll, configured to supply and receive the waste ribbon collected by the closed ribbon separator 104 so that inspection can be performed. The waste ribbons are supplied to the receiving rolls from the supply rolls and are photographed by the camera unit as part of the thermal transfer. At this time, the roll driving between the supply roll and the receiving roll is performed by the control unit 170, and the rotational speed of each roll is controlled according to the inspection speed.

The camera unit 120 photographs the surface of the waste ribbon moving between the supply roll and the receiving roll. The closed ribbon, which is thermally transferred to a wrapping paper, is repeatedly displayed in unit (A), which is a part of the separated characters, as shown in Fig. 6, which constitutes the same letter as the part printed on the wrapping paper. The camera unit 120 sequentially photographs the closed ribbon surface in a unit A, and the photographed image is displayed on the display unit 130 at the same time that the photographed image is transmitted to the reading unit 140 in real time.

The reading unit 140 reads out the partial error of the partial image using the image which is a part transmitted from the camera unit 120. [ 7 (a), there is no transcription at all, or only a part of the transcript is transcribed as shown in (b) and some of the transcripts are not transcribed as shown in Fig. 7 (b) . These errors, which appear on the lung ribbon, are the same on the wrapping paper, so the transfer error on the paper ribbon can be regarded as a transfer error on the wrapping paper.

The reading of the transfer error may be performed according to a predetermined program. For example, the total area of each unit may be compared with the transferred character area, and the error may be determined according to the ratio. At this time, the area occupied by the entire area of the unit and the character part is input in advance according to the content of the part, which can be inputted through the setting unit 150. Further, it is preferable that the reading for the error is set so as to allow an error in a predetermined range (see W in Fig. 8) with respect to the ratio of the area.

The setting unit 150 is a configuration for inputting a reference (read value) for reading an error and its range. As shown in FIG. 8, the setting unit 150 is configured such that the operator can directly input the reference of the ratio of the total area and the character area as a part, and the operator sets the ratio to 50 %, 0%, 35%, 80% can be set. The ratio of this area may be a value calculated in advance according to the contents of the partial person. Also, the setting unit 150 is configured to set a predetermined error range with respect to an error to be read based on the area ratio. That is, the operator can set the error range (W) so that the transfer can be read in a range of ± 5% based on 50% of the area ratio as shown in (a). The reading unit 140 judges whether or not a transfer error is a part of the closed ribbon according to the read reference and the error range set in the setting unit 150. [

Further, in the present invention, it is possible to divide the unit (A) which is a part including a plurality of characters into a plurality of cell units (C) including a part of characters, and to read out errors in units of cells. The content of a part of a person changes sequentially as part of the product, with most of the information being the same. Such a cell-by-cell reading method has the effect of setting the error indicated in the specific cell C 'to be changed not to be read as an error, so that the reading can be performed without resetting the frequently changed contents.

That is, as shown in Fig. 9, a part of the data is divided into a plurality of cells in a predetermined character unit and read, and the cell C 'to which the date information " (I.e., a change from ".11" to " .19 ") is a natural difference due to a change in date. Thus, the readout method can be performed for a cell-by-cell readout method which is part of "2017.06.11" to "2017.06.19" in the same setting mode. In addition, the efficiency of the error reading can be improved by preventing the reading from being performed on the cells C 'frequently changed.

The alarm unit 160 is configured to notify the operator of the occurrence of a transfer error by the reading unit 140, and may be configured as an alarm lamp or an alarm bell.

The control unit 170 controls the process of supplying, capturing, displaying, and reading the closed ribbon in accordance with an operator's command after the installed ribbon of the inspection object is mounted, and informing the operator of the occurrence of the error do.

5, when the waste ribbon attached to the waste ribbon loading unit 110 is supplied by the waste ribbon inspection apparatus 100 having the above-described configuration (S110), the camera unit 120 is photographed The reading unit 140 checks the inspection value and the set value for the area ratio at step S120 and determines whether the inspection value is included in the error range at step S130. If the inspection value is not included in the error range, (S140).

Meanwhile, in the present invention, it is preferable that the waste ribbon to be a target of the transfer error is a predetermined length unit. Processed food is packed in wrapping paper, then packed in boxes in a plurality of wrapping paper units or loaded on a pallet and then shipped. Therefore, it is preferable that the waste ribbon constitutes a unit of length corresponding to one or a plurality of pallets (i.e., stacking units) on which the processed food is finally loaded. This allows the product corresponding to the waste ribbon to easily track the loaded pallet if the defective product is shipped in pallets despite warranted errors, To track all products that are likely to have occurred.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
