Field of the Invention [0002] The present invention relates to a system capable of manufacturing and printing a plastic molded article in parallel. 2. Description of the Related Art As shown in FIG. 1, conventionally, when printing is performed on a plastic molded product, the molded product produced by a production means is taken out by a take-out means, collected, and then collected by a print means. They were arranged and arranged one by one so that they could be easily printed, and then printed by printing means to obtain finished products. [0003] This has the following disadvantages. Collecting the molded articles and arranging and arranging them one by one so that they can be easily printed by the printing means required a great deal of labor and time. [0004] In order to solve the above-mentioned drawbacks, a system for manufacturing and printing a plastic molded article characterized by the following requirements has been invented. (B) Having a production means for producing a plastic molded product. (B) A moving means for moving a part of the manufacturing means from the manufacturing means to the printing means, or from the printing means to the manufacturing means. (C) printing means for printing on the plastic molded product moved by the moving means; (D) A take-out means for taking out a finished plastic molded product printed by the printing means. (E) A computer for controlling the manufacturing means, the moving means, the printing means, and the take-out means, respectively. Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a block diagram of the present invention. The production means is a production apparatus such as a plastic injection molding machine for producing a plastic molded article (a part of the apparatus has a plurality of identical ones, and is moved by a moving means)
And an electronic circuit for ascertaining the production status of the molded product. The moving means moves a part of the manufacturing means to which the plastic molded article is attached from the manufacturing means to the printing means, or manufactures a part of the manufacturing means to which the plastic molded article is not attached from the printing means. Or moving means such as a turntable or a conveyor,
It is composed of an electronic circuit and the like for grasping the movement state of the molded article. The printing means includes a printing device using an inkjet method or the like for printing on a molded article, an electronic circuit for grasping the printing status, and the like. The take-out means is constituted by a take-out device such as an ejector pin for taking out the printed molded product from the system, an electronic circuit for grasping the take-out status, and the like. The manufacturing means, the moving means, the printing means,
Each means of the retrieval means is connected by a computer, and the means are controlled by the computer.

First, a comparison between the process of the present invention and the process of the present invention in FIG. 6 shows that the process of the present invention is greatly shortened as compared with the conventional process. This is a feature of the present invention that makes it possible to greatly reduce the time for manufacturing or printing by performing manufacturing and printing in parallel, and to omit the arrangement, arrangement, and delivery of molded articles. Further, with this system, for example,
Even if the upper part of the lid of the plastic bottle, which is a molded product, is polygonal, the molded product is located at a position before being taken out, so that printing can be easily performed at a correct position that does not impair the beauty of the shape. As an example, when the top of the lid of a molded plastic bottle is a regular triangle, characters and the like can be printed in parallel on the bottom. In the case of performing this printing by a conventional method, it is necessary to arrange the molded articles one by one.
