Description

  The present invention relates to a vertical collator system including a plurality of vertical collators.

  As a collating machine, a vertical collating machine having a plurality of feed stages in the vertical direction is known. Such vertical collators are limited in height, so the number of paper feed stages may not be large. For collation of paper with a large number of pages, multiple vertical collators are connected in series. The sheet bundles that are connected and collated by each vertical collating machine are sequentially stacked and discharged to the sheet stacking unit to form a sheet bundle having a required number of pages.

  FIG. 3A is an example of a vertical collating machine system having a plurality of conventional vertical collating machines. Each vertical collating machine 51 to 53 is equipped with control boards 51A to 53A, and While the vertical collating machine is timing, collation using a plurality of vertical collating machines is controlled.

  When collation is performed in this vertical collator system, a collation start signal (x) is sent from the control board 51A of the vertical collator 51 to the control board 53A of the rearmost vertical collator 53. The control board 53A of the vertical collating machine 53 performs collation, and the collation start signal (y) is sent to the control board 52A of the vertical collating machine 52 at the timing when the next vertical collating machine 52 feeds paper. Send. Similarly, the control board 52A of the vertical collating machine 52 performs a collation, and the collating start signal is sent to the control board 51A of the vertical collating machine 51 at the timing when the next vertical collating machine 51 feeds paper. Send (z).

  At this time, the rear vertical collating machine needs to grasp the situation where the paper of the previous vertical collating machine is loaded and adjust the timing for sending the collation start signal. That is, if all the sheets of paper are stacked on a plurality of vertical collators, the paper will come out neatly as shown in FIG. 3B. For example, as shown in FIG. In addition, the paper is loaded only on the shelf α of the vertical collating machine 51, the shelves β and γ of the vertical collating machine 52, and the shelf δ of the vertical collating machine 53. When paper is fed at the same timing as that shown in FIG. 3, there is a gap between the papers as shown in FIG.

  In order to prevent such a gap from being formed, the vertical collating machine 53 grasps the number of empty shelves in the vertical collating machines 51 and 52 and feeds paper by delaying the corresponding timing. Further, the vertical collating machine 52 delays the paper feeding timing by the amount of the position of the shelf on which the vertical collating machine 51 is stacked while adjusting the timing so that its own sheets overlap. By doing in this way, as shown in FIG.3 (d), paper can be overlap | superposed uniformly.

In addition, more complicated control is required for block paper feed (a function for dividing and feeding several sheets for a saddle stitching machine) and variable paper feed (a function for changing a paper feed shelf for each paper feed). There is.
In this way, in the method of controlling collation using a plurality of vertical collating machines while each vertical collating machine is timing, control with one vertical collating machine is simple. When a plurality of vertical collating machines are interlocked, the control of sheet feeding timing for each vertical collating machine becomes complicated and hinders scalability.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a vertical collating machine system that can simplify a control configuration and realize a control configuration with high expandability.

Vertical collator system of the present invention, the sheet feed tray for feeding a sheet feeding signal from the shelf control board one by one from the shelf that integrates sheet of predetermined pages are arranged in a plurality of stages in the vertical direction, each A plurality of vertical collating machines that discharge sheets stacked by sequentially shifting the sheets fed from the sheet feeding stage to the rear in response to the timing delay of the sheet feeding signal from the shelf control board of each sheet feeding stage. A vertical collating machine system comprising a plurality of vertical collating machines provided on a vertical collating machine provided in one of the plural vertical collating machines. , Adjusting the timing of the paper feed signal emitted from the shelf control board of each paper feed stage of the plurality of vertical collating machines based on the stacking status of the paper sheets of each paper feed stage, and adjusting the paper feed timing signal Is provided to each of the paper feed tray shelf control boards, and a paper feed timing adjusting means is provided for each paper feed tray shelf control board. Board outputs a sheet feed signal by the sheet feeding timing signal adjusted by the paper feed timing adjustment means, comprising the displacement width between each paper leaf Kamihataba discharged from the vertical collating machine always as constant It is characterized by that.

According to the vertical collating machine system of the present invention, a simple and highly scalable control configuration can be realized by issuing a paper feed instruction to each shelf from a board that controls the whole. Control is possible even by combining vertical collators and shelves with different amounts, and complex control can be realized.
In addition, since a plurality of paper feed shelves can be controlled by a single board, the control is very simple, it has excellent expandability, and it is easy to respond to changes in paper feed patterns, leading to the back. Since the vertical collator only has a function of controlling each shelf, the board configuration can be simplified.

  FIG. 1 is a diagram showing an embodiment of a vertical collating machine system according to the present invention. As shown in the figure, three rows of vertical collating machines 1A, 1B, 1C are connected in series. The vertical collating machine 1A includes a substrate 20 that controls the entire vertical collating machines 1A, 1B, and 1C, and a shelf control board 21A that controls a paper feed stage of each shelf of the vertical collating machine 1A. The vertical collators 1B and 1C are provided with shelf control boards 21B and 21C for controlling the paper feed stages of the respective shelves.

The vertical collators 1A, 1B, and 1C have the same structure except for the control board, and the specific structure will be described with reference to FIG.
These vertical collators 1A, 1B, and 1C are provided with eight paper feed stages 2a to 2h in the vertical direction. Paper feed rollers 3a to 3h are arranged in each paper feed stage, and paper is fed to the vertical conveying belt 5 via the vertical feed rollers 4a to 4h. The vertical conveyance belt 5 is driven by vertical conveyance belt drive rollers 6a and 6b arranged above and below. The paper fed from each paper feed stage is collated in page order to form a paper bundle, and is transported by the lateral transport belt 7.

  The lateral transport belt 7 is driven by lateral transport belt drive rollers 8a and 8b. The rotation direction of the lateral conveying belt 7 can be selected from the clockwise direction and the counterclockwise direction by switching the rotation direction of the driving rollers 8a and 8b. 9 is a pressure roller for pressing the collated sheet bundle and carrying it out of the lateral transport belt 7, 10 is a lateral feed roller, and 11 is transported from the vertical transport belt 5 to the lateral transport belt 7. This is a switching gate that switches the sheet bundle conveyance path to the left and right. The rotation direction of the lateral conveyance belt 7 is selected in either the clockwise direction or the counterclockwise direction according to the switching of the sheet bundle conveyance path by the switching gate 11.

  When the vertical collating machines 1A, 1B, and 1C are connected in series, as shown in FIG. 1, the sheet bundle collated with each of the vertical collating machines 1A, 1B, and 1C is transferred to the horizontal conveying belt. The switching gates 11A to 11B are switched so as to be conveyed in the same direction by 7A to 7C.

On the other hand, the shelf control boards 21A, 21B, and 21C always detect whether or not sheets are stacked in their respective sheet feed stages 2a to 2h by a sensor (not shown), and these sheets are stacked. Is notified to the control board 20 via the signal line 22.
Then, the control substrate 20 is notified from the substrates 21A, 21B, and 21C based on the stacking status of the sheets in the sheet feeding stages of the respective vertical collators 1A, 1B, and 1C. The paper feed timing from the 1C paper feed stage is adjusted (set), and the paper feed timing signal for each shelf is output to the shelf control boards 21A, 21B, and 21C.

  That is, the control board 20 outputs the paper feed signals of the paper feed stages 2a to 2h to the shelf control board 21C based on the stacking status of the papers of the paper feed stages 2a to 2h of the vertical collating machine 1C. At the timing when the sheet bundle PC collated by the vertical collating machine 1C passes through the switching gate 11B of the vertical collating machine 1B, the sheet bundle PB collated by the vertical collating machine 1B becomes the sheet bundle. Shelf control of the paper feed signals of the paper feed stages 2a to 2h of the vertical collating machine 1B based on the stacking condition of the papers of the paper feed stages 2a to 2h of the vertical collating machine 1B so as to be superimposed on the PC Output to the substrate 21B.

Similarly, the control board 20 has a vertical collating machine at a timing when the overlapped sheet bundle PC and sheet bundle PB are conveyed by the lateral conveying belt 7A and pass through the switching gate 11A of the vertical collating machine 1A. The vertical collation is performed based on the paper stacking status of each of the paper feed stages 2a to 2h of the vertical collating machine 1A so that the paper bundle PA collated in 1A is superimposed on the paper bundle PC and the paper bundle PB. The paper feed signals of the paper feed stages 2a to 2h of the machine 1A are output to the shelf control board 21A.
The bundle of sheets collated by the vertical collators 1A, 1B, and 1C connected in series in this way are sequentially stacked in the order of PC, PB, and PA, and the final vertical collator 1A. And is accumulated in the sheet bundle accumulating unit 12.

  As described above, the control board 20 of the vertical collating machine 1A grasps all the paper stacking statuses of the vertical collating machines 1A, 1B, and 1C, so that it is easy to adjust the feeding timing. The control board 20 of the vertical collating machine 1A issues a paper feed signal to each of the shelf control boards 21A21B and 21C, and the other vertical collating machines only feed paper by looking at the paper feed signal sent to each shelf. Therefore, the substrate configuration can be simplified.

  In the above embodiment, the vertical collating machine system in which three vertical collating machines are connected has been described. However, the number of stations and the number of shelves can be arbitrarily changed. In the embodiment, the first vertical collator 1A is equipped with a substrate for controlling the entire plurality of vertical collators, but the other vertical collators 1B and 1C have a plurality of vertical collators. It is also possible to mount a board for controlling the whole.
