回収する装置に関する。TECHNICAL FIELD The present invention relates to a delivery section of a sheet-fed printing press, in which powder for preventing blocking of printed matter is sprinkled in the delivery section before the printed matter is sequentially stacked on a stack of sheets with sheet piles. The extra powder that has been scattered is the endless chain of the delivery part and the holding rod,
The present invention relates to a device that is attached to a jaw and the like and that causes a blocking blocking powder that has been loaded to be scattered in a delivery unit by an injection air nozzle and that the scattered blocking prevention powder be collected by a dust collector.

から霧化状態に散布される。2. Description of the Related Art Generally, in a delivery section of a sheet-fed printing press, printed materials are stacked one by one on a sheet pile section, and by stacking sheets of paper in a stacked state, the first stacked sheets of paper are discharged one after another. The compression load depends on the weight of the incoming paper. For this reason, a printing failure called so-called blocking (set-off) occurs in which the ink of the printed material to be stacked is transferred to the back surface of the printed material to be stacked next. This blocking significantly reduces the value of printed matter and is a major factor in print claims. For this reason, in order to improve the inconvenience caused by blocking of the printed matter and adhesion of the paper, blocking prevention powder for preventing the blocking of the printed matter is sprayed in an atomized state from the powder spray nozzle spraying device.

表面に推積させる。The anti-blocking powder is generally a fine powder of starch or talc, and the particles are generally in the range of 70 μm or less, and particularly in the range of 10 μm to 30 μm, which are atomized by a powder spray nozzle spraying device. It is sprayed and deposited on the surface of the printed matter being conveyed in the delivery section.

ことが難しくなる。Further, if the printing speed becomes faster, the powder spray nozzle has to spray the powder in a short time, so that the powder amount and the jet pressure also become large, and the corrugated printed matter causes the powder particles to swirl and become more scattered. In addition, it becomes difficult to uniformly disperse the powder on the surface of the printed matter and deposit the powder.

If the suction power is increased, the printed matter conveyed by the endless chain will be undulated and the dust collection power cannot be increased, and the scattered blocking prevention powder will be delivered chain, holding rod, holding jaw or accessory device, equipment. The lubricating function is reduced by mixing with the lubricating oil inside, and the performance of the printing machine itself is deteriorated.

を効率良く集塵する目的で設けられている。The dust collecting device of the delivery section is generally provided except for the pile delivery section when the printed matter passes under the printed matter as much as possible, and the powder for preventing blocking sprinkled from the powder spray nozzle sprinkling device is efficiently supplied. It is provided for the purpose of collecting dust well.

汚れてしまうと言う大きな問題がある。For this reason, it is desirable to increase the suction force of the dust collecting device to collect the excess blocking preventing powder scattered from the powder spray nozzle, but the printed matter to be conveyed is collected at the dust collecting hole of the dust collecting device. There is a big problem that the printed matter becomes dirty because it is sucked.

印刷物は過剰となるパウダーが散布されている。The printed matter stacked on the paper stack plate of the delivery section of the sheet-fed printing press has a larger compressive load as the printed matter stacked underneath and a smaller compressive load as the printed matter stacked on the lower side has a blocking effect. The more piled up the printed matter is, the more likely it is to get up, and the amount of powder to be sprinkled continues to be adjusted according to the amount of the printed matter to be sprinkled. For this reason, the upper print is sprinkled with excess powder.

It is designed to be sprayed on.

Blocking prevention powder and the like adhering to the printed matter being conveyed in the delivery section has fallen off (a dripping phenomenon), and the quality of the printed matter has deteriorated.

In addition, there is a big problem that the operation rate of the printing machine is greatly reduced because the printing operation is stopped for a long time and the printing machine is cleaned.

It has been proposed to aspirate extra blocking powder. However, since the entire surface of the printed matter is sucked by the small holes of the suction plate of the dust collector, the surface of the suction plate becomes dirty, and at the same time, the back surface of the printed matter becomes dirty. There is a problem that stains are transferred to the surface of the printed matter that is stacked and the printed matter that is stacked on the destination becomes defective.

There has been proposed a blocking prevention powder spraying device for spraying blocking prevention powder regenerated by a powder spraying device from the upper surface of the device in a mist state from a powder spray nozzle. However, even if the collected powder passes through the filter, the dirty powder is mixed in, and the dirty powder is scattered on the printed matter, and the printed matter becomes dirty.

止することは不可能である。However, any of the blocking prevention powder dust collecting devices is a device for collecting the extra blocking prevention powder scattered from the powder spray dispersing device as efficiently as possible while the printed matter is being conveyed. It is a dust collecting device that minimizes adhesion to endless chains, holding rods, holding jaws, accessory parts around the delivery part, and devices, and blocking powder that has adhered. However, it is impossible to accurately remove the dust in a short time and prevent the quality of the printed matter from deteriorating due to dripping.
【００１８】また、ぼた落ちによる印刷物の品質低下を

方法が一部で実施されている。In addition, in order to prevent deterioration of the quality of printed matter due to dripping, some methods have been used in which no blocking preventing powder is used.

Therefore, the printing cost is high, and there is a problem that it is difficult to use except for a specific printed matter such as food-related products, which is concerned about the adverse effect of the powder for blocking prevention.
