JPS5927714B2 - Fully automatic creation processing method for printed matter bundles on rotary presses - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a system for automatically creating a small number of printed matter bundles (hereinafter referred to as fractional numbers) that cannot be mechanically automatically sorted during high-speed operation of a rotary printing press.

The counter stacker's ability to process printed matter, that is, count, sort, stack, and transport, is such that the minimum number of copies that can be processed (hereinafter referred to as a constant) during high-speed printing is approximately 25 copies, and it is capable of sorting a smaller number of copies (hereinafter referred to as a fraction). It was no longer possible to process the classification by machine without reducing the printing speed.

Therefore, in order to sort, for example, 12 copies of printed matter, automatic processing cannot be performed unless the printing speed of the rotary press is reduced to less than half of the above speed. This is a fatal setback for newspaper printing, which prioritizes speedy reporting. however,
The number of copies ordered from newsagents cannot necessarily be machine processed2
It is not necessarily a multiple of 5, and most cases involve a fraction. Therefore, conventionally, in order to respond to an order of 135 copies, for example, the following steps were taken: (1) 6 constant bundles of 25 copies and 150 copies, or (2) 5 constant bundles of 25 copies and the rest. One fractional bundle of 10 copies was created and supplied by hand.

Therefore, in (1) above, there is a physical waste in constantly supplying more newspapers than the number of copies ordered, and a waste in transportation. I felt a sense of sadness.

On the other hand, in (2) above, it is possible to eliminate the needless supply of copies, but at the cost of this, there is a waste of human time in which workers break bundles of constant 25 copies and manually create fractional bundles. I had a problem that I couldn't avoid. As an alternative to solve the above problem, the number of copies ordered, including odd copies, for example, 1.
The number of 35 copies is not divided into 25 copies each, but it is 135 copies at once.
One idea is to pile up a large bundle of parts and transport them. However, that idea is impossible for the following reasons. In other words, for example, folded printed matter such as newspapers has different thicknesses between the folded side and the terminal end, so it is impossible to stack them in the same direction, and the number of copies that can be stacked at one time is 24 pages of newspapers. 30 copies in case of
In the case of a 12-page newspaper, the maximum number of copies is 60, and any more will cause the load to collapse. Therefore, to create a large bundle of 61 copies of a 24-page newspaper, for example, you would normally need two small bundles of constant 25 copies and a fraction of 1.
It is necessary to stack one small bundle of one part in three tiers in different directions and carry it out while preventing the cargo from collapsing. It is an object of the present invention to automatically machine process a bundle of fractional printed matter, for which there was no other way than to separate and create them manually, at the same time as a fixed bundle of printed matter, by combining them in the process of creating them. The purpose of the present invention is to create and provide a highly efficient automatic creation method for fractional bundles that eliminates the above steps.

To summarize the concept of the present invention, it is impossible to directly mechanically divide a bundle of printed matter without reducing the operating speed. If we produce a fraction in a roundabout way as the remaining number of copies resulting from the combination of two divisions using a sorting means, that is, a constant and a larger number of copies that can be machine processed,
Focusing on the fact that automatic mechanical processing is possible, we first sorted the number of copies corresponding to the sum of the constant and the fraction using the first sorting device, and then used the second sorting and advance switching device installed downstream. The related operation is performed when a portion of the number of copies corresponding to a constant number passes through, and the remaining number of copies, that is, the number of copies corresponding to a fraction, is switched and introduced into a separate counter stacker.

The structure and operation of the present invention will be explained in detail below with reference to the drawings according to a specific embodiment.A counter 23 provided on the conveyance paths 12 to 18 counts, for example, 35 copies of printed matter, and 3 copies of the printed matter are counted.
When the fifth sheet of paper reaches the position of the sorting device 24, the sorting plate 24 acts to temporarily block the following paper row (see Figure 2a), separating the preceding and following paper rows. After creating a predetermined interval between
(See Figure 2b).

When, for example, the 25th copy of the preceding paper row reaches the sorting/travel path switching device 25, the switching plate 25 of the device operates to feed the rear 10 copies of the 35 preceding paper rows into the carrier 20, and then , is introduced into the counter stacker CS-B via the carrier 21 (see FIG. 2c).

Therefore, 25 parts of the front row are introduced into the counter stacker 1 CS-A, and 10 parts of the back row are introduced into the counter stacker 1 CS-B.
will be introduced to The number of copies divided by the division plate 24 is
If the number of copies re-sorted by the next sorting/route switching plate 25, that is, the number of copies introduced into counter stacker CS-A, is Y, then the remaining fraction z is given as counter stacker CS-B. will be introduced to

If the first number of divisions and accumulated.

Therefore, if the number of copies ordered by a newsagent is 92, each section board 24 and 25 will be marked with the number of copies ordered using perforated tape or a card. A total of 92 pieces, including 3 small bundles of constant number (25 parts) and 1 small bundle of fractional number (17 parts), are operated as shown in Table 1.
A large bundle 28 of parts is accurately produced and carried out on a conveyor 29 without causing any collapse.

Since the present invention is constructed and operated as described above, it is possible to mechanically automatically create fractional bundles during high-speed operation, which was previously considered impossible, and furthermore, the creation of fractional bundles can be performed simultaneously with the creation of constant bundles. Since we have made it possible by combining the following, we can immediately and accurately produce and supply large bundles of the ordered number of copies, even for orders that include odd quantities, without the need for any manpower and only by machine processing. As a result, conventional waste has been eliminated to a large extent, making it possible to supply printed matter in an extremely efficient manner.

Claims (1)

[Claims] 1. A sorting device 24 is provided on the conveyance path, and the sorting device is operated to divide a continuous stream of printed matter into a certain special number of copies, that is, the number of copies that can be processed during high-speed operation (hereinafter referred to as a constant) and a number of copies less than the constant (hereinafter referred to as a fraction). A divided stream is created which is divided into a number of parts corresponding to the sum of When the passage through the device is completed, the device is operated to redivide the divided flow into a constant number and a fraction, and at the same time, the remaining number of copies that have not yet passed through the device 25, that is, the number of copies corresponding to the fraction, is switched to a separate counter stacker.
