Description

The present invention relates to a printing system comprising a plurality of printing devices arranged in the substrate transport direction, wherein each printing device has two lanes as substrate transport lanes. An example of a printing system as described above is disclosed in Patent Document 1. The printing system (screen printing line) disclosed in Patent Document 1 includes two printing devices arranged in the direction of substrate transport and a shuttle conveyor positioned between them. Each printing machine is equipped with two conveyors, one at the front and one at the back, which form two transport lanes. The front lane, consisting of the front conveyor, is for holding the substrate and performing the printing process, while the rear lane, consisting of the rear conveyor, is a dedicated lane for transporting the substrate. The substrate is loaded into either the front or rear lane of the first printing apparatus (upstream printing apparatus). Substrates loaded into the front lane undergo printing there, are then transferred to a shuttle conveyor, and transported by the shuttle conveyor to the rear lane of the second printing apparatus (downstream printing apparatus). The substrate is then transported along this rear lane to the next process, namely the mounting apparatus. If there are substrates in the front lane of the first printing device, the subsequent substrates are transported to the rear lane of the first printing device. The substrates transported to the rear lane are then transferred to a shuttle conveyor, which transports them to the front lane of the second printing device. After undergoing printing in this front lane, the substrates are then transported to the mounting device. In the above printing system, the substrates that are brought into the first printing device in this manner are alternately printed by the first printing device and the second printing device. In such a printing system, each printing device and shuttle conveyor is controlled individually by an independent control device. Therefore, if, for example, the second printing device stops, the printed substrates cannot be transported from the first printing device through the second printing device (rear lane) to the mounting device during that time, making it difficult to continue substrate production. Similarly, if the first printing device stops, the substrates (unprocessed substrates) in the rear lane of the first printing device cannot be transferred to the shuttle conveyor during that time, also making it difficult to continue substrate production. Japanese Patent Publication No. 2011-235584 The present invention aims to provide a technology that contributes to improving the continuity of substrate production in a printing system that includes two printing devices arranged in the substrate transport direction, each printing device having two lanes for transporting substrates. A printing system according to one aspect of the present invention includes an upstream printing device located upstream in the substrate transport direction, a downstream printing device arranged adjacent to the downstream side of the upstream printing device, an upstream control device for controlling the printing process of substrates in the upstream printing device, and a downstream control device for controlling the printing process of substrates in the downstream printing device, wherein the upstream printing device includes an upstream main lane for transporting and transporting substrates to be printed in the upstream printing device, and an upstream sub-lane for transporting substrates to pass through the upstream printing device without undergoing printing, the downstream printing device includes a downstream main lane for transporting and transporting substrates transported along the upstream sub-lane as substrates to be printed in the downstream printing device, and a downstream sub-lane for transporting printed substrates transported along the upstream main lane to pass through the second printing device, wherein the upstream control device is configured to control the upstream main lane and the downstream sub-lane, and the downstream control device is configured to control the downstream main lane and the upstream sub-lane.
