Description
~Z6~(~33 The present invention relates to a method of and a system for identifying articles to be worked on a production line and, more par.ticularly, to a method of and a system suitable for use in a production line which handles a variety of kinds of articles to be workedO In the following description, the articles will be refer to as works.
It is a current practice to produce different kinds of products from different works by utilizing a single production line. In this type of production line, a plurality of works of differen-t kinds are successively conveyed for different kinds of machining or processing, so that it is necessary to discriminate or identify the type of each of the successively conveyed works, i..e., -to identify the kinds and specifications of the works, in order that the works may be correctly subjected to the respective disignated processings such as attaching of parts by, for example, a robot, welding and coating.
Hither-to, several methods have been proposed for enabling the identification of works, such as discrimina-tion of the shapes of the works by means of a photoelectric tube, judging of the work specifications through sensing the position of cards on respective works by means of a /
': , ~ ~ ~ ' ' ' photoelectric tube, and so forth. Vnfortunately, however, these known methods can provide only a few items of information, and there is an increasing demand for a me-thod ~hich can provide greater amount of information. To cope with this demand, it has been proposed to use a card for each work, the card carrying various data concerning -the type and specification of the work. When identifying the works, i.e~, for detecting the -types and specifications of the works, the information carried by the card on each work is read by a card reader.
This method enables the identification of type and specification fairly well, but still suffers from the following disadvan-tages. Namely, this method requires the selec-tion of a card amongst different kinds of cards, so that correct card may be attached to the corresponding work. This method also requires preparation of a new card carrying data concerning any new work each time a new type of work is used. Thus, the efficiency of production is lowered due to the necessity for the preparation, selection and attaching of the cards to the works.

BRIEF DESCRIPTION OF THE DRAWINGS
Fig. 1 is an illustration of a production line to which an embodiment of the invention is applied; and Fig. 2 is a flow chart explaining the method of the invention for identifying works.
DESCRIPTION OF THE PREFERRED EMBODIMENTS:
Referring to Fiy. 1, a transportation conveyor 22 is disposed through a plurality of areas such as areas 10, 12 for attaching cards to successive works, areas 14, 16 for processing by robots, and areas 1~, 20 for processing by automatic processing machines. A plurality of cards 24 are placed in the area 12. The cards 24 carry marks or signs peculiar thereto, such as serial Nos., different symbols and pat-terns.
Card readers 26, 32 and 34 are disposed in the areas 12, 16 and 18, whereas TV cameras 28, 30 are disposed in .
the areas 14, 20. Industrial robots 36, 38 are installed in the areas 14, 16, whereas automatic processing machines 40, 42 are placed in the areas 18, 20.
The output from the card reader 26 is transmitted to a line computer 46 through a relay station 44, while the outputs from the TV camera 28 and the card reader 32 are transmitted to the line computer 46 through a relay station 48. The outputs from the card reader 34 and -the TV camera 30 are transmitted to the line computer 46 through a relay station 50.
A host computer 52 stores all the information concerning the types and specifications of the works 54 which are conveyed by the conveyor 22. The data is stored in accordance with the order of the works on the conveyor.
The thus stored data is transmitted to the line computer 46. Upon receipt of the data from the host computer 52 and the information derived from the relay stations 44, 48 and 50, the line computer identifies the type and, hence, the specification of each of the works 54 which are successively conveyed by the conveyor, and delivers to the robots 36, 38 and the automatic machines 40, 42 various processing information concerning the processing which is to be performed on each work.
The operation will be explained hereinunder with reference to Fig. 2.
12~S1033 In a first step (STEP 100), the data concerning types and specifications of works 54 which are to be processed during one particular day is stored in the host computer 52 in accordance with the order of processing of the successive works~ The works are then conveyed in accordance with the above-mentioned order by the conveyor.
When a work 54 arrives at the area 12 (STEP 102), the host computer 52 delivers the processing information concerning this work 54 to the line computer 46 (STEP 104). At the same time, any desired card 24a selected from a group 24 of cards is selected and inserted into the card reader 26 (STEP 106). The card reader 26 reads the sign peculiar to the card 24a, e.g., serial No. or a mark, and deiivers a signal representing the sign to the line computer 46 through the relay terminal 44 (STEP 108). The line computer 46 therefore stores the data concerning the types and specifications of the successive works 54 arriving at the area 12, in relation to the signs peculiar to the cards (STEP 110). Then, the cards 24a are attached to corresponding works 54, and are conveyed together with the works to the areas 14, 16, 18, 20 for processing by means of the conveyor 22~
The works 54 carrying respective cards thus successively arrive at the processing areas 14, 16, 18 and 20 where the robots 36, 38 and automatic machines 40, 42 are installed (STEP 112), and the signs peculiar to the cards on successive works 54 are read by TV cameras 28, 30 and signals corresponding to such signs are transmitted to the line computer 46 through the relay stations 48, 50 (STEP
114).
When the work 54 has arrived at the areas 16, 18, the operator extracts the card 24a and inserts the same into the card reader 32 or 34, so that the card reader reads the sign peculiar to this card and .the content is transmitted to the line computer 46 through the relay stations 48, 58 (STEP 116).
As the successive works 54 are conveyed by the conveyor 22 to the areas 14, 16, 18 and 20, respectively, the signs peculiar to the cards 24a attached to the works 54 are read by the TV cameras 28, 30 and card readers 32, 34, and the thus read data is transmitted to the line computer 46. Upon receipt of the data, the line computer 46 identifies the types and specifications of the works on the basis of the sisns read from the cards 24a (STEP llS).
The identified work types and specifications are then transmitted to the robots 36~ 38 and the automatic machines 40, 42 through the relay stations 48, 50 (STEP 120), so that the robots 36, 38 and the automatic machines 40, 42 perform the required processings or machinings on these works 54 in respective areas (STEP 122).
As will be understood from the foregoing description, according to the invention, any desired card selected from a group of cards each having its peculiar sign is attached to each of successive works of diferent types conveyed by a production line for producing different kinds of products, and the required processings or machinings are performed in respective processing or machining areas in accordance with the data based on the signs peculiar to the cards on respective works. It is, therefore, possible to eliminate necessity for the troublesome works such as the preparation of cards for respective types of works and the selection of the cards. In addition, the risk of error in the selection and preparation o the cards is obviated, contributing to a simplification of the work identification and, hence, to a reduction iA the installation cost.
