In the disclosed method, as a larger pile of papers is being assembled, a portion of this pile is first assembled within a time not shorter than the time for unloading that pile. so that the time for assembling the remaining portion of the larger pile should be in excess of the pile unloading time, whereafter a smaller pile is then assembled, and then the remaining portion of the greater pile is assembled simultaneously with unloading of the assembled smaller pile from the respective bin. The method provides for assembling smaller piles containing any amount of newspapers, even a pile of one newspaper.

1 Claim, 4 Drawing Figures METHOD OF ASSEMBLING PILES OF NEWSPAPERS CONTINUOUSLY DELIVERED BY A ROTARY PRESS The present invention relates to methods of assembling piles of newspapers delivered in a continuous stream, and, more particularly, to methods of assembling piles of newspapers continuously delivered by a rotary press.

The present invention may be employed to the utmost effectiveness in automatic production lines effecting both the printing of newspapers, and their subsequent treatment and handling, including such operations as assembling piles of the newspapers, the packag' ing of these piles, and their subsequent transportation.

At present, there are widely known methods of assembling piles of newspapers which are continuously delivered by a rotary press, wherein the stream of newspapers is alternatingly directed into bins for assembling therein a greater pile, and a smaller pile, respectively, which piles are subsequently unloaded from these bins within a specified period related to a given printing speed, and in which method one of the piles, eg the greater one, is completely assembled, whereafter the other pile is assembled (cf. US. Pat. No. 3,702,186, Cl. 270-6).

By these known methods the piles may be assembled, with the minimum possible amount of newspapers being limited, and which depends on the printing speed. This is explained by that fact that otherwise it would be impossible to unload the greater pile within the allotted time when the smaller pile is being assembled. Consider the following example at a printing speed of 40,000 revolutions per hour for the printing cylinders, a greater pile including 50 newspapers is assembled in 2.25 seconds, and can be unloaded from the bin in L second, while the smaller pile including 25 to 27 newspapers is assembled within 1.1 seconds, with the unloading time being the same. Said amount of newspapers in the smaller pile is determined by the consideration that if the smaller pile includes, for example, twenty newspapers, its assembling time would be only 0.9 seconds. In this case, after this smaller pile has been assembled, the stream of newspapers is to be directed into another bin where a greater pile including 50 newspapers had been previously assembled, and the present newspapers would be superimposed on those of said greater pile, because the latter could not have been unloaded within 0.9 seconds.

Therefore, the above example substantiates the previous statement that the minimum number of newspapers in the smaller pile is limited, and depends on the printing speed. This limitation of the number of newspapers in the smaller pile would make impractical the employment of equipment for effecting the aforesaid known methods in automatic continuous lines effecting printing and subsequent handling, and treatment of newspapers, since their employment is tantamount to the necessity of running such lines at a relatively low printing speed.

It is therefore an object of the present invention to eliminate the above disadvantage.

it is an object of the present invention to provide a method of assembling piles of newspapers which would make possible the assembly of piles containing any desired amount of newspapers, even as low as one newspaper in a pile.

It is another object of the present invention to provide a method of assembling piles of newspapers, which would allow the assembly of such piles at any printing speed.

It is a further object of the present invention to provide a method of assembling piles of newspapers which would make possible the introduction of automation into the process of handling, and treatment of printed newspapers.

These and other objects are attained by a method of assembling piles of newspapers, wherein the stream of newspapers is alternatingly directed into bins for as sembling therein a greater pile, and a smaller pile, respectively, with the piles being subsequently unloaded from the bins within a specified period related to a given printing speed, and in which method, in accordance with the present invention, as said greater pile is being assembled, a portion of this pile is first assembled within a period not shorter than the pile unloading time, so that the time of the assembling of the remaining portion of this greater pile is in excess of said pile unloading time, where after the smaller pile is assembled, while said remaining portion of the greater pile is assembled, with simultaneous unloading of the smaller pile from the respective bin, a smaller pile is assembled in each said bin after the assembling therein of a greater pile.

The proposed method makes it possible to assemble smaller piles containing any amount of newspapers, with at least one newspaper, since, due to the interruption of the process of assembling of the greater pile, and since the time of assembling of the first portion of this pile is in excess of the pile unloading time, it becomes possible to unload the previously assembled greater pile during this time of assembling said first portion. Thus, if the pile unloading time equals 1.0 second, the first portion of the greater pile is assembled in l.l seconds, which time is quite sufficient for unloading the previously assembled greater pile. Thus, the proposed method may be employed at any printing speed, and with the printing process being a continuous one. The above features of the herein disclosed method are ensured by the bin alternation, i.e. by the fact that in each bin after the assembling of a greater pile therein, a smaller pile may be assembled.

The invention will be better understood from the following discription of the preferred embodiments thereof, when read with reference to the accompanying drawings, wherein:

FIG. 1 is a schematic view of an apparatus for effecting the proposed method of assembling piles of newspapers;

FIG. 2 shows the apparatus of FIG. 1 illustrating the assembling of the smaller pile, with the operation of assembling the greater pile having been interrupted;

FIG. 3 shows the apparatus of FIG. 1, illustrating the assembling of the remaining portion of the greater pile, with simultaneous unloading of the smaller pile;

FIG. 4 illustrates graphically the timing of the interruption of the operation of assembling the greater pile.

The herein disclosed method of assembling piles of newspapers essentially resides in that, as the greater pile of newspapers is being assembled, a portion of their pile is first assembled during the time of which is not shorter than the pile unloading time, so that the time of assembling the remaining portion of this greater pile should be also in excess of the pile unloading time spective bin, and a smaller pile being assembled in eachbin after the greater pile has been assembled therein.

The operation'of assembling piles of newspapers delivered in a continuous stream by a rotary press is performed as follows:

A folder drum 1 (FIG. I) of a rotary press continuously delivers a stream of newspapers 2 directed by a deflector 3, and a spider drum 4into a bin 5 for assembling therein a greater pile. After a time not shorter than the pile unloading time of the apparatus employed, assembled in the bin 5 is a portion a of the greater pile, and 'then the deflector 3 is switched for directing the stream of newspapers 2 into another bin 6 (FIG. 2) for assembling therein the smaller pile. After the operation of assembling the smaller pile in the bin 6 has been completed, as is shown in FIG. 3, the stream of newspapers 2 is again directed into the bin 5 to be assembled ther'ein within a time in excess of the time for unloading the pile from either of the bins, the remaining portion of the greater pile 8, and to effect the simultaneous unloading of the smaller pile from the bin 6 in a direction shown by arrow A.

After the greater pile 8 has been completely assembled, the stream of newspapers 2 is redirected into the bin 6 to assemble therein a successive greater pile, while the previously assembled greater pils is unloaded from the bin 5. Unloading of the piles may be effected by any suitable means, e.g. by means of a conveyor.

The timing of the interruption of the operation for assembling a greater pile may be graphically illustrated, as shown in FIG. 4. In this drawing:

1 is the time for assembling the greater pile in seconds;

r, is the time for assembling the portion a of this greater pile, also in seconds;

1 is the time for unloading of the pile from either bin,

in seconds;

: is the time for assembling the remaining portion of the greater pile, in seconds;

is the time for which the operation of assembling the greater pile is interrupted to assemble the smaller pile, in seconds.

EXAMPLE The task is to assemble a greater pile containing 50 newspapers, and a smaller pile containing l0 newspapers. With the printing speed equalling 40,000 revolutions per hour for the printing cylinders, the greater pile is assembled in 2.25 seconds, and the smaller pile is assembled in 0.45 seconds, with the time for unloading a pile from either bin being 1.0 second.

First, the operation of assembling the greater pile containing 50 newspapers is commenced. After a portion of this pile has been assembled in 1.1 second, the assembling operation is interrupted. Then, the operation of assembling the smaller pile containing l0 newspapers is begun, and completed, which takes only 0.45 seconds. After the smaller pile has been assembled, the remaining portion of the greater pile is assembled within a time equalling 2.25 seconds minus l.l second, i.e. in l.l5 second. During the course of this period of 1.15 second, the smallerpile is unloaded from the respective bin, which operation takes, as it has been stated, only 1.0 second. During the remaining 0.15 second (1.15 sec. minus 1.0 sec. makes 0.15 sec.), i.e. even before the operation of assembling the greater pile is completed, the bin from which the smaller pile has been unloaded is ready to receive therein a stream of newspapers. After the operation of assembling the greater pile has been completed, the newspapers are directed into this empty bin, wherein the operation of assembling the next greater pile containing 50 newspapers is commenced, while the already assembled greater pile is unloaded from the respective bin in l.0 second. Thus, this last-mentioned pile is unloaded before the operation of assembling the successive greater pile, with its interruption being effected after 1.1 seconds from the moment of commencing the assembling. After the assembling operation has been interrupted, the stream of newspapers is directed into the bin from which the greater pile has been unloaded so to assemble therein the successive smaller pile containing 10 newspapers. Thereafter the described cycle is repeated.

As can be seen from the above example, the herein disclosed method makes it possible to assemble smaller piles containing any amount of newspapers, at any printing speed.

What is claimed is:

l. A method of assembling piles of newspapers being continuously delivered by a rotary press, comprising the operation of: directing the stream of newspapers into a first bin for assembling therein a greater pile of newspapers; assembling in said first bin a portion of said greater pile within a time not shorter than the time of unloading a pile from said bin; interrupting the process of assembling said greater pile in said first bin; directing said stream of newspapers into a second bin for assembling therein a smaller pile of newspapers, redirecting said stream of newspapers after said smaller pile has been assembled into said first bin, and assembling therein the remaining portion of the greater pile of which the assembling has been interrupted, and within a time in excess of said pile unloading time; unloading said smaller pile from said second bin during the period of the assembling of said remaining portion of said greater pile in said first bin; re-directing said stream of newspapers into said second bin for assembling therein the first portion of a greater pile; unloading said first-mentioned greater pile from said first bin, and repeating the aforementioned operations of assembling the greater and smaller piles alternatingly in said bins.
