Description

  The present invention belongs to the technical field of a variable number of bookbinding machines for creating various notification materials for individuals such as direct mail. In particular, it is possible to create an on-demand booklet that can increase the number of enclosed sheets rather than just normal paper by matching the number of sheets containing thin paper in variable numbers and binding them, so that the number of enclosed sheets can be increased from that of regular paper. The present invention relates to a variable number bookbinding machine.

Conventionally, an adhesive is used when a booklet is created by collating a plurality of printed continuous sheets. That is, when an adhesive is applied to the back of the collated paper, the adhesive penetrates shallowly not only into the back but also into the inside. Sheets collated by the adhesive force when the adhesive is dried are combined to form a booklet. However, it has been difficult to inline this process due to problems such as drying time. In view of this, there is a proposal of a method of collating by discharging glue from a glue nozzle and applying line glue on one side in the sheet flow direction (Patent Document 1 and Patent Document 2).

  Next, embodiments of the present invention will be described with reference to the drawings. An example of the configuration of the variable number bookbinding machine of the present invention is shown in FIG. In FIG. 1, 1 is a roll paper supply unit, 2 is a center slitter, 3 is a sheet cutter, 4 is a conveyance conveyor, 5 is a name / collation means, 6 is a spiral dropping unit, 7 is a main conveyance line, 8 is a tact, 9 Is a conveying conveyor, 10 is a BCR for name and collation, 11 is an aligning section, 12 is a stitcher, 13 is a discharge line, 14 is a trimmer section, 100 is thin paper (roll), and 200 is normal paper (folded).

The thin paper 100 is a thin paper in the form of a roll (winding body) obtained by winding a thin paper of a web (long sheet) around a paper tube. Here, the thin paper 100 means a paper of 50 kg / sixty or less. Such a thin paper 100 is a paper that is difficult to bind with a conventional bookbinding machine due to characteristics such as low strength and weakness as compared with normal paper. The thin paper 100 is printed in advance. The printing form is such that two pages are arranged in the left-right direction (web width direction), and a plurality of them are continuously arranged in the vertical direction (web supply direction). The print content includes information for identifying those pages. Information for specifying a page is encoded and printed in the form of a barcode, a two-dimensional code, or the like.
Here, the normal paper 200 means a paper of 55 kg / sixty or more plates. Paper between 50 Kg / 46 plates and 55 Kg / 46 plates can be categorized as either according to their properties.

The roll paper supply unit 1 unwinds the roll-shaped thin paper 100 and supplies it to the center slitter 2. The roll paper supply unit 1 includes a support mechanism for the roll-shaped thin paper 100, a pin tractor that fits and feeds pins into the pin holes of the marginal part of the unrolled thin paper 100, and the like.
The center slitter 2 is cut in the supply direction (longitudinal direction of the web) at a substantially central position of the supplied thin paper 100 and divided into two in the left-right direction (web width direction). For cutting with the center slitter 2, for example, a disk cutter or the like is used.
The sheet cutter 3 overlaps the center slit left and right surfaces, and cuts in the left and right direction with a margin slit and a predetermined top and bottom dimension to make the thin paper 100 into a sheet form. A rotary cutter or the like is used for the horizontal cutting by the sheet cutter 3.
The conveyance conveyor 4 conveys the sheet-like thin paper 100. The transported thin paper 100 reaches under the name and collation BCR 5, passes through the paper, reaches the spiral dropping means 6, and is delivered.

  The nameplate / collation BCR 5 is a barcode reader that reads a barcode printed on the thin paper 100 while the sheet-shaped thin paper 100 is being transported by the transport conveyor 4. The barcode includes data for specifying the thin paper 100, and it can be determined whether or not it belongs to one specific booklet based on the data. That is, the name / collation BCR 5 is an example of a code reader in name collation means (not shown) that performs processing for selecting and stacking the thin papers 100 belonging to one specific booklet. In the present invention, the barcode reader is not limited, and an OCR, a two-dimensional code reader, or the like can be used.

  The name identification means includes a code reader and a data processing unit (not shown). The data processing unit determines whether or not the name and collation BCR 5 belongs to one specific booklet based on the data read from the thin paper. The print contents (print pages) belonging to one specific booklet are printed as a group in a roll-like thin paper 100 in the order of the pages. Therefore, the sheet-like thin paper 100 is also transported by the transport conveyor 4 in the page order. Therefore, the data processing unit inputs the data read by the name / collation BCR 5 from the thin paper 100 and detects whether the data has changed from data belonging to one specific booklet to data belonging to another booklet. When there is a change, it is determined that the name identification is completed, and a completion signal is output.

  The spiral dropping unit 6 superimposes and collects the name-bound thin papers 100 and inputs a name identification completion signal to cause the collected thin papers 100 to fall vertically on the main transport line. In the example shown in FIG. 1, the spiral dropping unit 6 operates as a pair of two spirals (spiral members). The two spirals hold the thin paper 100 near the opposite sides of the thin paper 100 in sheet form. By holding at least two spirals, it is possible to prevent the alignment of the thin paper 100 from being deteriorated due to bending. Depending on the shape of the spiral, a structure in which two or more are used is preferable because the prevention effect is further enhanced.

  When the spiral dropping unit 6 superimposes and stacks the thin paper 100, the two spirals stop rotating. The thin paper 100 transported by the transport conveyor 4 then enters the stopped spiral gap. Then, the left and right sides of the thin paper 100 are positioned by the both-side abutting mechanisms provided in the entering path. In addition, the thin paper 100 stops by coming into contact with a stopper provided at the destination. That is, the two spirals receive the sheet-like thin paper 100 conveyed by the conveyor 4. When there is a thin paper 100 already stopped and held in a spiral, the thin paper 100 to be identified is sequentially entered and superimposed thereon. When all the thin papers to be identified have entered, the spiral dropping unit 6 inputs a completion signal output from the name identification means.

  When the completion signal is input, the spiral dropping unit 6 rotates the two spirals. As a result, the named thin paper 100 falls to the main transport line 7. At this time, the pitch and rotation period of the two spirals are the same. The two spirals are rotated in opposite directions by the drive mechanism. A frictional force is acting between the two thin papers 100 named as spirals. The rotational directions of the two spirals are rotational directions in which the thin paper 100 named by the friction force is pressed toward the stopper. With this configuration, the named thin paper 100 is dropped to the main transport line 7 while maintaining the horizontal posture and the sides are aligned without disturbing the accumulation state, and is transferred to the main transport line 7.

  The main transport line 7 is a transport line that performs other bookbinding processing on the thin paper 100 that has been identified. The main transport line 7 hooks and transports the thin paper 100 named by the transport claws. A range from the conveyance nail to the next conveyance nail is referred to as a tact 8. A plurality of tacts 8 are arranged, and the tacts 8 are moved intermittently in units of the tact 8, that is, in units of the range from the conveyance nail to the next conveyance nail so that each tact 8 can be processed one by one. The main transport line 7 has a mechanism for The cycle of the intermittent movement is a cycle (time interval) that includes both the time required for name identification of the thin paper 100 and the time required for name identification of the normal paper 200 described later. Each tact 8 is loaded with a thin paper 100 that has been identified, and sequentially moves to the next tact 8 to be arranged. In the example shown in FIG. 1, each tact 8 of the main transport line 7 is provided with an origami supply unit, a stitcher 12, and a discharge line 13.

  The normal paper 200 is a normal paper in a folded form in which a normal paper of a web (long sheet) is folded at a perforation or the like and stored in a cardboard box or the like. Here, the normal paper 200 means a paper of 60 kg / sixty or more plates. The regular paper 200 is a paper suitable for bookbinding in a conventional bookbinding machine. The normal paper 200 is printed in advance. The printing form is such that two pages are arranged in the left-right direction (web width direction), and a plurality of them are continuously arranged in the vertical direction (web supply direction). The print content includes information for identifying those pages. Information for specifying a page is encoded and printed in the form of a barcode, a two-dimensional code, or the like.

The origami supplying unit supplies the folded normal paper 200 to the cutter. The cutter cuts the supplied normal paper 200 in a folded form into a predetermined size to obtain a normal paper 200 in a sheet form. The origami supply unit includes a stage on which the folded normal paper 200 is placed, a pin tractor that fits and feeds pins into the pin holes of the marginal part of the normal paper 200 drawn from the upper side, and the like.
The transport conveyor 9 transports a sheet of regular paper 200. The transported normal paper 200 reaches under the name and collation BCR 10, passes through the paper, reaches the main transport line 7, and is delivered.
The nameplate / verification BCR 10 is a bar code reader that reads a bar code printed on a normal sheet 200 in the form of a cut sheet in the course of being conveyed by the conveyor 9. Since the name / collation BCR 10 is the same as the name / collation BCR 5 described above, the detailed description is omitted. Note that the regular paper 200 that has been identified is superimposed and stacked on the thin paper 100 that has been identified and belongs to the same booklet in the tact 8 of the main transport line 7.

The aligning unit 11 aligns the thin paper 100 that has been identified and the regular paper 200 that has been superposed on the thin paper 100. The aligning unit 11 includes, for example, an inclined sheet placement surface, an abutment surface provided on two sides with low inclination and perpendicular to the sheet placement surface, and a vibration mechanism. At least a side that is the back of the booklet and one side that is perpendicular to the side are in contact with the abutting surface, and vibrations are applied and aligned.
The stitcher unit 12 is an example of a wired binding means for binding by wire, and a single booklet is formed by binding (binding) the aligned thin paper 100 and regular paper 200 with a wire.
The discharge line 13 receives the bound booklet from the main transfer line 7 and conveys it to the trimmer 14, and discharges the booklet trimmed by the trimmer 14.
The trimmer 14 is arrange | positioned at the discharge line 13 in the example shown in FIG. The trimmer 14 cuts (decorates) the side portions (usually three sides) of the booklet into predetermined dimensions so that the end face of the booklet is beautiful.
