The present invention relates to a corrugated cardboard underlay supply device that lays corrugated cardboard paper on the lower surface of the flexible body bundle so as not to be deformed or crushed by binding by a machine.

[Conventional technology]

In a newspaper delivery line, a bundle of newspapers delivered by a counter stacker, which has a particularly small number of bundles, is weak when it is bound by a binding machine as it is, and it deforms or collapses when it is tightened. Therefore, the following device is known as a device for preventing this.

That is, the folding device disclosed in Japanese Examined Patent Publication No. 54-23610 discloses a newspaper bundle that is conveyed using a fork to fold it from four folds to eight folds, and has a small thickness. It is a device that strengthens and prevents it from deforming and crushing when binding, and the corrugated cardboard underlay feeding device shown in Japanese Utility Model Laid-Open No. 64-36373 applies corrugated cardboard paper to the lower surface of the conveyed newspaper bundle. This is a device that reinforces newspaper bundles and prevents them from deforming or collapsing during binding.

[Problems to be Solved by the Invention]

However, although these devices have been able to prevent deformation and the like when binding newspapers, there are still some problems.

First, in the folding device disclosed in Japanese Examined Patent Publication No. 54-23610, it is necessary to stop the newspaper bundle on the conveyer conveyor to perform the folding operation in the course of the processing, and the processing takes time. .

In addition, the mechanism of the device is complicated, maintenance is difficult, and the space is large, and a large installation space is required.

On the other hand, in the corrugated cardboard underlay feeding device disclosed in Japanese Utility Model Laid-Open No. 64-36373, since the corrugated cardboard paper storage portion of this device is provided below the conveying means of the flexible body,
There is a problem that it is difficult for the operator to visually check the remaining amount of the corrugated paperboard stored in the corrugated paperboard storage section, and it is difficult to detect troubles and abnormalities at an early stage.

Further, in this conventional corrugated board underlay supply device, since the corrugated board supply section and the take-out section of the corrugated board storage section are provided at the same position, the corrugated board supply to the corrugated board storage section is replenished. In this case, the supply of the corrugated paperboard to the flexible member transporting section must be temporarily stopped, which causes a problem that the continuity of the processing operation is lost.

The present invention has been conceived in view of the above, and it is possible to easily visually monitor the corrugated paperboard storage portion, easily confirm the remaining amount of corrugated paperboard, and easily detect troubles or abnormalities at an early stage. Corrugated paper can be replenished to the corrugated paper storage without stopping the flexure transport device.
