Description

  The present invention relates to a paper sorting weighing device which indicates a sorting position when a required number of sheets is sorted from a bundle of insert advertisements, for example.

  Conventionally, insert advertisements that are inserted into newspapers and delivered to subscribers are stored in empty locations in the warehouse in the order in which the corresponding insert advertisements are received when a distribution request is received from an advertising agency or sponsor. Thereafter, the stored advertisements are sorted into the number of copies for each newspaper store in accordance with the distribution date, and loaded into the transport vehicle in accordance with the delivery route.

  Usually, the sorting operation is to unpack a bundle of folded advertisements that have been received, and based on the sorting information on the label that indicates which newspaper dealer the bundle of folded advertisements is for, Sorted into the number of sheets, the sorted advertising inserts are bundled again, further labeled, and forwarded to the delivery department by route.

In the sorting work, as a specific example of sorting the folded advertisements into the number of copies for each newspaper store, the height of the stacked folded advertisements is pressed in the direction in which they are compressed against the stacked folded advertisements. Measured by the measuring means without applying pressing force, the thickness per sheet is calculated from the height and the total number of sheets by the calculating means, and the height and thickness and the number of sheets to be sorted are sorted by the position indicating means. An apparatus that determines the position of the number of sheets to be displayed and displays the stacked sheets is known (see, for example, Patent Document 1).
Japanese Patent No. 3457627 (pages 3-5, Fig. 1)

  However, in the conventional technology, when measuring the height of a plurality of stacked sheets of paper, a pressing force is not applied to the stacked folded advertisements in the direction in which they are compressed. Depending on the condition, especially when the paper is folded, the thickness varies greatly depending on how the paper is folded (hereinafter referred to as “stacked state”). As a result, multiple stacked sheets There is a problem that the total height of the paper cannot be measured accurately, and even if the sorting height is specified, it cannot be accurately sorted at that position.

  The present invention has been made paying attention to such problems, and its main purpose is to accurately and accurately specify a specified number of sheets from a plurality of sheets of which the total number is known regardless of the stacked state of the sheets. It is an object of the present invention to provide a high-performance paper-sorting weighing device that can quickly sort.

That is, the paper sorting weighing device according to the present invention stacks a plurality of sheets of which the total number is known on a mounting table that can be moved up and down, and presses the plurality of stacked sheets while pressing them. A device that indicates the sorting height position at which a specified number of sheets are separated from a plurality of sheets by measuring the total height of the sheet, and can be moved up and down by the servo motor. A direction in which a contact member is brought into contact with the uppermost paper among a plurality of sheets and compressed against a plurality of stacked sheets by operating a servo motor. And a total height measuring unit that measures the total height of a plurality of sheets pressed by the pressing unit based on the amount of movement of the contact member obtained from the control amount of the servo motor. And the total number of sheets of paper The pre-sort height position for separating the designated number of sheets of the plurality of sheets pressed by the pressing means based on the designated number indicating the total height and the total height measured by the total height measuring means And a zero point position that is set in advance as a reference position for separating a specified number of sheets and that contacts the mounting table and the contact member before measuring the total height. However, it is arranged so that it cannot move in the vertical direction at a certain sorting reference position, is pressed by the pressing means, and is raised and lowered based on the sorting height position calculated by the sorting height position calculating means. It is characterized by comprising a sorting height position instruction means for instructing a sorting height position for a plurality of sheets of paper.

  Here, “the total number of sheets is known” means that when the total height of a plurality of sheets of paper is measured, in addition to the total number of sheets of the plurality of sheets to be measured, the total number of sheets is known. The remaining sheets obtained by sorting the specified number of sheets from the plurality of sheets are also included in the known total number. As a specific example of the former, there is one in which 2,000 sheets are in a bundled state like a folded advertisement before sorting. Further, as a specific example of the latter, an example in which the remaining number (for example, 1,500) obtained by separating a specified number (for example, 500) from 2,000 is an example in which the total number is known. Can be mentioned.

  In addition, “instructing the sorting height position with respect to a plurality of sheets pressed by the pressing means” means, for example, that the sorting height position recognized by the apparatus by calculation is the nail height This means the one instructing while making contact with the paper using the shape and the one instructing non-contact using the laser or the like.

  If this is the case, from the measurement of the total height of the stacked sheets of paper to the indication of the preparative height position is performed while pressing the stacked sheets of paper, for example, stacking of the sheets It is possible to accurately indicate a sorting height position for sorting a specified number of sheets while suppressing errors caused by the state and the like.

  That is, it is possible to provide a high-performance paper sorting and weighing device that can accurately collect a specified number of sheets from a plurality of stacked sheets without being affected by the stacked state of the sheets.

  The paper is preferably a newspaper insert advertisement. This is because a folded advertisement delivered to a subscriber after being folded into a newspaper is once transported to a folding center before being delivered to a newspaper store. Since the bundle is carried out in a bundled state, and the form of carrying out from the folding center is that the bundle is separated and carried out according to the newspaper dealer's store, It is particularly effective for taking.

  Here, the insertion advertisement is a concept including not only a single piece that is not folded but also a booklet-like shape in addition to a half-folded one.

  In order to easily cope with a change in the total number of sheets, it is desirable to include a total number receiving unit that receives the input of the total number.

  In order to sort out a desired designated number of sheets, it is preferable that a designated number acceptance unit for accepting an input of the designated number is provided.

  In addition, the sorting height position calculation means is configured to sort the specified number of sheets from the lower or upper side of the plurality of stacked sheets, so that the sorting height position calculating unit is the lowest or uppermost of the stacked sheets. If the sorting height position is calculated with reference to the sheet of paper, the reference position for sorting the specified number of sheets can be easily set.

  In order to further prevent waste from being further separated from the remaining paper, after a specified number of sheets have been collected from a plurality of stacked sheets, a new designation is made from the remaining remaining sheets. The sorting height position calculating means includes a total number of a plurality of sheets, a designated number indicating the number to be sorted, and the total height measuring means. In addition to the total height measured in step (b), based on the new designated number of sheets, a sorting height position for sorting a new designated number of sheets of the remaining sorted paper that has been pressed by the pressing means is determined. It is desirable to be configured to calculate.

  Another aspect of this is that after a specified number of sheets are separated from a plurality of stacked sheets, a new specified number of sheets can be separated from the remaining sheets. The total height measuring means is configured to measure the total height of the remaining separated paper that is pressed by the pressing means, and the preparative height position calculating means performs the sorting. Based on the total number of remaining sheets, the designated number indicating the number of sheets to be newly sorted, and the total height of the remaining sheets separated by the total height measuring unit, the sheet is pressed by the pressing unit. A configuration in which a sorting height position for sorting a new specified number of sheets of the remaining sorted sheets in a state is calculated.

  If the sorting height position instructing means uses a sorting nail that can be inserted between the surfaces of a plurality of stacked sheets, the sorting height position is instructed. Although the configuration is simple, it is possible to indicate the preparative height position accurately.

  Further, when a plurality of stacked sheets are pressed with a constant force by the pressing means, stable measurement accuracy can be obtained if the pressing means is configured to always press with a constant force.

  As described above, according to the paper sorting weighing device of the present invention, a plurality of stacked sheets of paper are pressed from the measurement of the total height of the stacked sheets of paper to the indication of the sorting height position. Since the process is performed in a state, for example, it is possible to accurately indicate a sorting height position at which a specified number of sheets are sorted while suppressing an error caused in a stacked state of sheets.

  That is, it is possible to provide a high-performance paper sorting and weighing device that can accurately collect a specified number of sheets from a plurality of stacked sheets without being affected by the stacked state of the sheets.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  The paper sorting weighing apparatus A according to an embodiment of the present invention is incorporated in the paper sorting system S shown in FIGS. 1 and 2, and the total number of sheets is determined in the sorting and distribution center sorting each newspaper store. It is used to sort out a plurality of known papers (for example, insert advertisements inserted into newspapers). This sorting and distribution center temporarily stores bundles of insert advertisements received from clients requesting distribution, and unpacks bundles of insert advertisements when the number of insert advertisements to be shipped to each newspaper store is determined. Using the paper sorting weighing device A, a predetermined number of sheets are collected, sorted into a bundle of folded advertisements for each newspaper store, and shipped as a sorted finished product. is there.

A binding band is hung in a direction perpendicular to the direction of the band, and the band is bound so as to form a so-called cross. In addition, without using the automatic binding apparatus D, it is not hindered to manually bind the sorted products.

  Now, returning to this discussion, the paper sorting weighing device A will be described in detail.

  As shown in FIGS. 1, 3, 8, and the like, the paper sorting and weighing apparatus A is mounted on the mounting table 1 on which the folded advertisement conveyed by the folded advertisement conveying conveyor B is mounted, and on the mounting table 1 described above. There are provided pressing means 2 for pressing the stacked folded advertisements J0 in a compressing direction, and a sorting claw 32 that can be inserted between the stacked folded advertisements J0. The claw part 3, the actuator 4 having a function as a sorting claw insertion control means for moving the claw part 3 in the horizontal direction, and the specified number of folded advertisements J1 from the stacked folded advertisements J0 are sorted. The cradle 5 for supporting the remaining folded advertisement J2, the sag detecting means 6 for detecting that the fold advertisement hangs down from the cradle 5, and the fold down advertisement being returned to the cradle 5 side. An electronic control unit X (not shown) for controlling the position of the return means 7, the mounting table 1, the sorting claw 32 and the receiving table 5, and controlling the pressing force of the pressing means 2, and the electronic control unit And a touch panel type display panel 8 that accepts an input related to a setting change of a parameter for X to perform a predetermined operation and displays a parameter.

  Hereinafter, each part is demonstrated concretely.

  The mounting table 1 has an upper surface as a mounting surface 11, and is provided with a pair of belts 11 </ b> B that are exposed at substantially the center of the mounting surface 11 so as to be substantially flush with the mounting surface 11. . This pair of belts 11 </ b> B conveys while placing both end sides of the folded advertisement. Moreover, in this embodiment, this mounting table 1 is supported by the axis | shaft 12 which comprises the raising / lowering means to raise / lower vertically.

  In addition, in this embodiment, in order to appropriately place the folded advertisement that has been transported on the mounting table 1, the contact body 13 protrudes on the mounting surface 11 (protruding position), and after the paper sorting is completed. By storing in the mounting table 1 (storage position), the advertisement on the mounting surface 11 can be carried out. The abutment body 13 is a columnar steel material having substantially the same cross section in the longitudinal direction, and is selectively positioned at the protruding position or the storage position by the electronic control unit X described later.

  The pressing means 2 always presses the plurality of folded advertisements J0 stacked on the mounting table 1 with a constant force in the direction of compressing them, and is mounted on the mounting table 1. Of the plurality of folded advertisements J0, a metallic abutting member 21 that abuts on the folded advertisement placed at the top, and this abutting member 21 is moved in the direction of approaching and separating from the mounting table 1 described above. The servo motor 22 is provided.

  In the present embodiment, the servo motor 22 is configured so that the height position of the contact member 21 can be controlled in 1 μm steps. However, the present invention is not limited to this. In addition, the contact member 21 is configured to press the plurality of folded advertisements J0 placed on the mounting table 1 with a force of about 30 kg. In addition, depending on the embodiment, it can be appropriately changed to one capable of stable height measurement. Furthermore, the contact member 21 is not limited to a metal member, and for example, a resin member may be used.

  As shown in FIG. 3 and the like, the claw portion 3 has a substantially rectangular flat plate shape and can come into contact with a folding advertisement placed on the mounting table 1, and from the base end of the contact portion 31. A sorting claw 32 having a substantially pentagonal shape in plan view bent at a right angle is provided, and these parts are formed by plastic deformation of a steel material or the like.

  More specifically, the contact portion 31 is connected to the actuator 4 that moves the claw portion 3 in the horizontal direction. Of course, the claw portion 3 may be moved also in the vertical direction.

  The sorting claw 32 includes a rectangular piece 321 having a rectangular shape in plan view on the base end side, and a triangular piece 322 having a triangular shape in plan view on the distal end side. Thus, when the sorting claw 32 is inserted into the folded advertisement J0 that is stacked while being pressed by the pressing means 2 by the actuator 4, the sorting claw 32 is moved by the triangular piece 322. Can be inserted with less resistance.

  The actuator 4 moves the sorting claw 32 positioned at the sorting height position so as to be inserted between the sheets of the plurality of folded advertisements J0 pressed by the pressing means 2. It functions as an insertion control means.

  As shown in FIGS. 1, 3, etc., the cradle 5 is connected to an advancing / retreating means 51 for advancing and retracting the cradle 5 in the horizontal direction, and has a rectangular element 52 having a rectangular shape in plan view on the base end side. And a triangular element 53 having a triangular shape in plan view on the distal end side. In this embodiment, each part is made of steel and is made of Teflon (registered trademark). ) Coated with resin. Thus, when the cradle 5 inserted between the paper surfaces is pulled out by the advancing / retreating means 51, the remaining folded advertisement J2 and the receiving surface 50 adhere to each other by static electricity, negative pressure, friction or the like (hereinafter referred to as friction). It can suppress from a material surface.

  Further, in the present embodiment, a plurality of grooves 5x (not shown) extending along the insertion direction are provided on the receiving surface 50 that is the upward surface of the cradle 5. Due to the plurality of grooves 5x, the receiving surface 50 of the cradle 5 has a concavo-convex shape extending in the insertion direction, and functions as an adhesion suppressing means. That is, when pulling out the cradle 5 inserted between the paper surfaces, it is possible to prevent the remaining folded advertisement J2 and the receiving surface 50 from adhering to each other due to friction or the like. Instead of the grooves 5x, for example, minute irregularities may be provided on the entire receiving surface 50.

  The sagging detection means 6 detects the sagging when a part of the remaining folded advertisement J2 supported by the cradle 5 hangs downward from the cradle 5, and in this embodiment, It is configured using an optical sensor.

  The return means 7 hangs down when the sag detection means 6 detects that a part of the remaining folded advertisement J2 supported by the cradle 5 hangs downward from the cradle 5. It comes into contact with a part of the insert advertisement and returns to the cradle 5 side.

  Specifically, the return means 7 has a bar 71 that can selectively position the other end side at the normal position or return position with the one end side as the center, and the other end side of the bar 71 at the normal position or return position. And a motor (not shown) that is controlled to be selectively positioned. In the present embodiment, the pair of bars 71 are spaced apart so as to substantially correspond to the width dimension of the cradle 5. As a result, when one side edge of the folded advertisement hangs down from the cradle 5, one of the pair of bars 71 is positioned at the return position while contacting one of the bars 71 with the suspended folded advertisement, and the other side edge. When the hangs down, the other bar 71 can be operated in the same manner. That is, even if any side edge of the folded advertisement hangs down from the cradle 5, the side edge of the advertisement hanging down by the pair of bars 71 can be returned to the cradle 5 side.

  As shown in FIG. 4, the electronic control unit X includes a CPU 101, an internal memory 102, an external storage device 103, an input / output interface 104, and the like. The electronic control unit X operates the CPU 101 and peripheral devices according to the program stored in the internal memory 102, and as shown in FIG. 5, the total number receiving means X11, the designated number receiving means X12, the total height It functions as the height measuring means X13, the preparative height position calculating means X14, the preparative height position indicating means X15, and the like.

  Hereinafter, each means will be described in detail.

  The total number acceptance means X11 accepts the input of the total number, and is configured using the display panel 8 or the like.

  Specifically, for example, if the total number is 1,000, the value 1,000 of the total number input by touching an operation button of the display panel 8 described later is accepted. In the present embodiment, 2,000 sheets are set as the default value of the total number of sheets.

  The designated number receiving means X12 accepts the input of the designated number, and is configured using the display panel 8 or the like.

  Specifically, for example, if the designated number is 300, 300, which is the value of the designated number inputted by touching an operation button of the display panel 8 described later, is accepted.

  The total height measuring means X13 is the total height m1 of the plurality of folded advertisements J0 being pressed by the pressing means 2, that is, the contact surface of the contact member 21 from the mounting surface 11 of the mounting table 1. The distance to 211 is measured (refer to FIG. 8 (2)). Specifically, in this embodiment, the mounting surface 11 of the mounting table 1 is lifted by the lifting / lowering means 12 and brought into contact with the lower end of the sorting claw 32, and the control amount of the lifting / lowering servomotor (not shown) is controlled. Set to 0 (this is the “sorting reference position”). In this state, the contact surface 211 of the contact member 21 is brought into contact with the mounting surface 11, the control amount of the servo motor 22 is set to 0 (zero), and the contact member 21 is moved from the mounting table 1. While separating again, the mounting table 1 is lowered, a folded advertisement to be sorted is placed, raised again, set to the sorting reference position, and pressed by the pressing means 2 via the contact surface 211 of the corresponding contact member 21. Based on the amount of movement of the contact surface 211 obtained from the control amount of the servo motor 22, the total height m1 of the folded advertisement J0 is measured (the position of the contact surface 211 at this time is “initial contact”). It will be “surface position”.)

  Note that the 0 (zero) point position of the placement surface 11 and the contact surface 211 is very important for ensuring the accuracy of the sorting height, so the (zero) point of the placement surface 11 and the contact surface 211 is This is set at the time of starting the paper sorting apparatus A (for example, at the start of daily work). Further, the mounting surface 11 is 0 (zero) from the reading value of the encoder of the lifting servo motor when the total height of the sorting work is measured or the second or later sorting work is set at the sorting reference position. A function for automatically checking the misalignment of dots is added to the paper sorting weighing apparatus A.

  In the present embodiment, the sorting height position calculating means X14 sorts the plurality of stacked folded advertisements J0 so as to sort the designated number of folded advertisements J1 from the lower folded advertisement. The sorting height position is calculated based on the lowest insertion advertisement among the insertion advertisements J0. In addition, the prepaid amount based on the highest insert advertisement among the plurality of stacked insert advertisements J0 so that the specified number of insert advertisements J1 is sorted from the upper insert advertisement among the plurality of insert advertisements J0 stacked. The position may be calculated.

  The sorting height position calculating means X14 is configured to press the pressing based on the total number of the plurality of inserted advertisements J0, the designated number indicating the number to be sorted, and the total height m1 measured by the total height measuring means X13. The sorting height position for sorting the specified number of inserted advertisements J1 in the plurality of inserted advertisements J0 pressed by the means 2 is calculated.

Specifically, it is calculated by the following formula (Formula 1).
(Expression 1) Sorting height position a1 = (total height m1 measured by the total height measuring means X13) × (designated number of sheets x1 indicating the number of sheets to be sorted) / (total number of folded advertisements J0) x0)
Here, x1: designated number to be sorted for the first time Note that the sorting height position calculation means X14 sorts the specified number of inserted advertisements J1 from the plurality of stacked folded advertisements J0. It is also possible to calculate a sorting height position when sorting a new designated number of inserted advertisements J1 from the remaining inserted advertisements J2. In this case, the sorting height position is calculated by the following formula (Formula 2).
(Expression 2) Sorting height position a2 = (total height m1 measured by the total height measuring means X13) × (designated number of sheets x2 indicating the number of sheets to be sorted) / (total number of the folded advertisements J0) x0)
Here, in the same manner as x2: the specified number of sheets to be sorted for the second time, it is possible to obtain the height positions for the third and subsequent times.

  In this case, the total height of the remaining folded advertisements J2 may be measured again, and the total number of the remaining folded advertisements J2 may be used to obtain the designated number of sorting height positions. Further, it can be expected that the sorting accuracy is ensured by checking whether or not the sorted amount is appropriate from the total height and the remaining total number of the remaining inserted advertisements J2. Further, in the second and subsequent sorting, the reading of the encoder or the reading of the scale provided separately can be substituted without raising the mounting table 1 to the sorting reference position.

  The sorting height position instruction means X15 instructs the sorting height position calculated by the sorting height position calculation means X14 to the plurality of folded advertisements J0 that are pressed by the pressing means 2. To do. Specifically, in the present embodiment, with respect to a plurality of folded advertisements J0 that are pressed by the pressing means 2, the sorting claws 32 are moved at the sorting height position by operating the actuator 4. By inserting it, the preparative height position is indicated.

  The sorting height position instructing means X15 is not limited to instructing the sorting height position calculated by the sorting height position calculating means X14, but also accepts the sorting height position measured externally. It has a function as a height position receiving means, and can be configured to be able to instruct based on the received preparative height position.

  The display panel 8 takes in data relating to sorting from a host computer (not shown) or changes the designated number when collecting the designated number from the folded advertisement J0 in which the total number is known and stacked. Operation buttons and numerical buttons (both not shown) for inputting a specified number of sheets and changing the setting of the total number are displayed so as to be able to correspond, and the operation buttons have a total height m1. A measurement start button and the like for performing automatic measurement are included.

  Next, the operation of the paper sorting weighing apparatus A of the present embodiment will be described with reference to the flowcharts shown in FIGS.

  First, as shown in FIG. 8 (1), when the folding advertisement J0 conveyed by the designated number of sheets conveying conveyor B2 is placed on the placing table 1 (step S101), the pressing means 2 is activated. Then, as shown in FIG. 8 (2), the total height m1 of the folding advertisement J0 on the mounting table 1 is measured while pressing the folding advertisement J0 (step S102). Then, the sorting height position calculation means X14 calculates the sorting height position using the measured total height m1 of the inserted advertisement J0, that is, based on (Equation 1) (step S103). For example, “total number of inserted advertisements J0” is 2,000, “specified number indicating the number to be sorted” is 500, and “total height m1 measured by the total height measuring means X13”. If it is 200,000 μm, the preparative height position is calculated as 50,000 μm from the mounting surface 11 of the mounting table 1.

  Next, the electronic control unit X moves the shaft 12 constituting the lifting / lowering means (not shown) so that the sorting claw 32 is positioned at the sorting height position calculated by the sorting height position calculating means X14. Operate and move the mounting table 1 as shown in FIG. 8 (3) (step S104). In this way, the electronic control unit X operates the actuator 4 with respect to the sorting nail 32 positioned at the sorting height position, and as shown in FIG. Is inserted (step S105). And if the nail | claw 32 for sorting is inserted with respect to the insertion advertisement currently pressed, the electronic control part X will operate the servomotor 22, and the press by the press means 2 will be cancelled | released (step S106).

  And the electronic control part X operates the axis | shaft 12 which comprises a raising / lowering means (not shown), and as shown in FIG. 9 (5), the mounting base 1 is moved a little below, and it is in a preparatory height position. A gap SK is formed immediately below a certain sorting claw 32 (step S107). Next, with respect to the gap SK, the electronic control unit X operates the advance / retreat means 51 to insert the cradle 5 as shown in FIG. 9 (6) (step S108).

  Then, the remaining folded advertisement J2 is placed on the receiving tray 5, and the designated number of folded advertisements J1 are placed on the placing base 1.

  Further, the electronic control unit X operates the shaft 12 that constitutes the raising / lowering means, and the loading surface 11 of the loading table 1 is moved upward as shown in FIG. 9 (7). The electronic control unit X operates the pair of belts BLT to convey the specified number of folded advertisements J1 toward the address mounting device C. (Step S110), the state shown in FIG. If it is not to be further sorted (step S111), the process is terminated. If it is to be further sorted, the operations shown in FIGS. 10 (9) to (13) are performed, and a further specified number of sheets are sorted. .

  As described above, the paper sorting measuring device A according to the present embodiment includes a plurality of stacked folding sheets from the measurement of the total height m1 to the indication of the sorting height position of the plurality of stacked folding advertisements J0. Since the advertisement J0 is performed in a pressed state, for example, an error generated in a stacked state of folded advertisements or the like can be suppressed, and the sorting height position at which the specified number of folded advertisements J1 are sorted can be accurately indicated.

  In addition, in the conventional sorting method in the weight measurement, first, roughly, weigh and know the difference in the number of sheets (weight difference) from the specified number of sheets, and then again, the difference in number from the specified number of sheets (weight) It was an iterative work to reduce the difference. Therefore, since time is required for sorting, there is a problem that the sorting time is secured at the expense of sorting accuracy. According to the paper sorting measuring device A of the present embodiment, since the sorting height position corresponding to the specified number of sheets is obtained, that is, after weighing, the sorting is completed at one time. The taking time is fast and the height is measured in the pressed state, so that it can be sorted with sufficient accuracy.

  That is, there is provided a high-performance paper sorting and weighing apparatus A that can accurately collect a specified number of sheets from a plurality of folded advertisements J0 without being affected by the stacked advertisement advertisements. be able to.

  Further, since the total number receiving means X11 for receiving the input of the total number is provided, it is possible to easily cope with the fluctuation of the total number.

  In addition, since the designated number receiving means X12 for receiving the designated number is provided, the desired designated number can be easily sorted.

  In addition, the sorting height position calculation means X14 is configured to sort out a specified number of sheets from the lower folded advertisement among the stacked folded advertisements J0, among the stacked folded advertisements J0. Since the sorting height position is calculated on the basis of the bottom insert advertisement, the reference position for sorting the specified number of sheets can be set easily.

  In addition to the total number of the inserted advertisements J0, the designated number indicating the number to be sorted, and the total height m1 measured by the total height measuring means X13, Based on the new designated number of sheets, a fraction height position for sorting a new designated number of inserted advertisements in the remaining folded advertisement J2 that has been pressed by the pressing means 2 is calculated. Therefore, it is possible to favorably suppress the occurrence of waste by further sorting from the remaining inserted advertisement J2.

  The sorting height position instructing means X15 indicates the sorting height position using the sorting claws 32 that can be inserted between the sheets of the plurality of folded advertisements J0 stacked. Therefore, it is possible to indicate the preparative height position accurately with a simple configuration.
