摘要： PROBLEM TO BE SOLVED: To dispense with the necessity to assign screens stored in a stocker and thereby reduce manhours for operation by automatically replacing the screen in referance to data stored in a means for storing screen information in a stocker of the screen, when an NC program is selected anew. SOLUTION: When continuously producing different types of a product 1, an NC program to be used for production is previously registered with plural machines. Then the production is initiated at the start 2. When continuing the production 4, the machines automatically select the NC program to be used for the following production from among plural NC programs which are previously registered 5. Further, a desired screen is assigned to an automatic screen replacement device 6, based on the stocker number recorded in a screen data part, referring to the structural data of the NC program selected by the machine.

摘要： PURPOSE:To eliminate a waste of time and trouble during change of a supply component by constituting an inner diameter part of a take-up reel for taking up a top tape of a coating tape holding part for holding a part in contact with a top tape and a separation component which enables separation from a coating tape. CONSTITUTION:A cassette body 1 has a part for holding a component packed to a tape form and a part which can take up a coating tape for unloading the component packed to a tape form, and can supply a component. A coating tape holding part 7 and a separation part 8 constitute an inner diameter component. When a supply component is exchanged, it is required to eliminate a top tape 4 taken up to the coating tape holding part 7 and the separation component 8. In the process, the separation component 8 can be moved to a position 8' by moving a fixed component 9 to a position 9'. An outer circumference of the coating tape holding part 7 and the separation component 8' to the top tape 4 is shortened by this movement, and the top tape 4 can be thereby removed readily.

摘要： PROBLEM TO BE SOLVED: To shorter the time required for checking manhours and print results which need to be checked by providing a step to check print results with the help of a camera for recognition along with a cleaning action during the cleaning action, and carrying out offset of registration of the print results to reflect it on print correction action thereafter. SOLUTION: When printing is performed and a following cleaning operation is carried out, a cleaner part 8 is moved forward and backward to clean the rear face of a screen. In this case, a stage transfer part 4 located on the rear face of the screen, located in such a relation that the part 4 interferes with the cleaner part 8, retreats to the loader side together with a substrate. In addition, a camera 3 for recognition checks the print results of the substrate which is parked to the loader side, along with the cleaning action, to check the difference between the shifts of screen pattern and a substrate pattern and automatically effect offset registration of the print results. Thus, the print results serve for substrate print correction thereafter. Besides, if the cleaning operation is completed, the stage transfer part 4 is moved to transport the substrate.

摘要： PROBLEM TO BE SOLVED: To reduce manhours for operation by causing screens stored in a stocker to hold information relative to a use status, and determining whether a screen to be used next is still unused or already used with the help of a printing press and performing an automatic solder-feed action after the replacement of the screen in compliance with the use status of the screen. SOLUTION: Production is initiated at the start 1, then a screen is replaced 4 when the production is continued 3. After that a printing press refers to information relative to the use status of the screens stored in each of the stages of a stocker to check whether the screen to be used is still unused or already used 5. If the screen is still unused, an automatic solder-feed action is performed 6. On the other hand, if the screen is already used, the automatic solder-feed action is not carried out and instead, the production of a new version of the existing type is initiated 2. If the production is discontinued 3, it is ended 7.
