Description

Conveying system Technical Field The present invention relates to a conveying system. Background Conventionally, in various conveying systems, a process is performed on an image generated by capturing a conveyed object, and thus counting, whether or not the conveyed object is good, posture discrimination, detection of a conveying state (speed, density, interval, etc.), and the like are performed. Examples of the conveying system include the devices described in patent documents 1 and 2 below. Patent document 3 and patent document 4 disclose methods in which, in the above-described conveying system, the posture of the conveyed object is changed by blowing an air flow to the conveyed object so as to change the posture of the conveyed object on the conveying path, and thereby the posture of the conveyed object is supplied in order and uniform. Prior art literature Patent literature Patent document 1 Japanese patent laid-open publication No. 2017-121995 Patent document 2 Japanese patent laid-open publication No. 2019-169010 Patent document 3 Japanese patent laid-open No. 11-240615 Patent document 4 Japanese patent laid-open No. 2000-264430 Disclosure of Invention However, in the above-described conveying system, when the air flow blowing pressure or the blowing timing is inappropriate when the posture of the conveyed object is changed, the changed posture may be inappropriate or the changed posture may become irregular. Therefore, the air flow blowing pressure and timing are required to be adjusted according to the type of the conveyed article, and there are problems in that it takes time to perform the adjustment operation every time the posture of the conveyed article is changed and a skilled person is required to perform the adjustment appropriately. The present invention has been made to solve the above-described problems, and an object of the present invention is to achieve a speed-up and simplification of an operation mode adjustment operation of a conveyance object posture changing means in a conveyance system. In order to solve the above problems, a conveying system according to the present invention includes a conveying device that conveys a conveyed article along a conveying path and has a posture changing portion that changes a posture of the conveyed article in the middle of the conveying path, an image acquisition unit that acquires an image of the conveyed article, a conveyed article discrimination unit that performs image processing on an image portion of the conveyed article in a determination area set on an upstream side of the posture changing portion to obtain conveyed article discrimination information related to the posture of the conveyed article, a conveyed article posture changing unit that performs posture change of the conveyed article at the posture changing portion when the conveyed article discrimination information is information that requires posture change of the conveyed article, and a conveyed article confirmation unit that performs image processing on an image portion of the conveyed article after the posture change by the conveyed article posture changing unit to obtain conveyed article confirmation information related to the posture of the conveyed article. According to the present invention, since the state after the posture change of the conveyed object generated by the operation of the conveyed object posture changing means can be confirmed by obtaining the conveyed object confirmation information related to the posture of the conveyed object, the operation mode of the conveyed object posture changing means can be adjusted while confirming the information, the operation of adjusting the operation mode of the conveyed object posture changing means can be facilitated, and the posture changing mode of the conveyed object at the posture changing position can be highly accurately performed. In the present invention, it is preferable that the apparatus further includes a conveyance object posture change determination unit that obtains conveyance object posture change information indicating a relationship between the conveyance object identification information and the conveyance object confirmation information. According to the present invention, by obtaining the conveying object posture changing information indicating the relationship between the identification information before the posture change of the conveying object and the confirmation information after the posture change of the conveying object, the relationship between the operation mode of the conveying object posture changing means and the posture changing state of the conveying object generated by the operation of the conveying object posture changing means can be more easily confirmed. In the present invention, it is preferable that the transport object confirming means obtains the transport object confirming information by performing image processing on an image portion of a confirming area set in a position or a
