Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card cutting machine for manufacturing a card by cutting a plurality of printed sheets for a card into a predetermined size, and more particularly, a slitter unit for cutting along a sheet conveying direction. It is related with the card cutter which can make manufacture of this, and the slitter unit for card cutters.

A card cutting machine for cutting a standard-sized card paper on which card printing has been performed into a predetermined size and creating a plurality of cards, one sheet at a time from a paper feed tray containing card sheets A paper feed unit for sending out, a cutting unit for cutting paper into a predetermined card size, and a discharge unit for discharging a plurality of cards created by the cutting unit are sequentially provided on the paper transport path. Composed.
In the cutting unit of such a card cutter, the slitter mechanism 10 for cutting card paper in the transport direction (that is, in the vertical direction), as shown in FIG. The upper and lower slitters 1 and 2 extend in a direction orthogonal to each other, and each of the slitters 1 and 2 has a plurality of rotary blades 12 and a pair of upper and lower shafts 11 and 21 that rotate in opposite directions. 22 is provided with a predetermined interval.

  As the upper and lower slitters 1 and 2 rotate, the blade edges of the pair of rotary blades 12 and 22 come into sliding contact with each other, and the card paper passing between the slitters is cut in the vertical direction. 11, in the case where a margin portion 32 (that is, a middle dove) is provided between card regions 31 arranged in the vertical direction as in the card paper 3 having the layout shown in FIG. 32 may be sandwiched between adjacent rotary blades (22a, 22b) and may stagnate around the rotary blades. In order to prevent such a situation, as shown in FIG. There has been proposed a technique in which a guide member 23 formed of a plate-like body having a through-hole for passing through is provided between rotary blades (22a, 22b) (Patent Document 1).

  By inserting a guide member 23 having a through hole through the shaft 21 together with the rotary blades 22, 22a, 22b, a lower slitter 2 is formed, and together with the upper slitter 1, it can be rotated in the housing of the card cutter. It is attached.

Japanese Patent No. 3881327

However, in the layout of the card paper 3, there are various cutting modes, such as when the margin part 32 is not provided between the card areas 31, and when the width of the margin part 32 is changed or the number of columns in the vertical direction is changed. In order to eliminate the uneconomical of purchasing different card cutting machines for each cutting mode, a slitter mechanism for performing vertical cutting is often provided in a state of being housed in a housing. When manufacturing and repairing the slitter unit, two slitters have to be assembled in a narrow space of the housing, so that workability is extremely poor.
In addition, when the slitter is assembled, the guide member interferes with the opening edge of the housing, which may cause contact with the rotary blade or damage to the blade edge.

  Therefore, an object of the present invention is to provide a card cutter and a slitter unit for a card cutter that can improve workability when manufacturing or repairing a slitter unit.

  In order to solve the above-described problems, the present invention provides a predetermined interval in the axial direction between each of a pair of shafts arranged in the direction perpendicular to the paper conveyance direction with the paper conveyance path interposed therebetween. By holding and arranging a plurality of rotary blades, the first and second slitters are formed, and the peripheral edges of the rotary blades facing each other of the first and second slitters rotate while sliding, In a card cutting machine configured to include a slitter unit in which a slitter mechanism capable of cutting along the sheet conveyance direction is housed in a casing, the penetrating that can penetrate the shaft of the second slitter And a notch continuous from the penetrating portion, and a mounting portion extending in a direction perpendicular to the flat plate portion, the chip of the paper at the peripheral edge opposite to the mounting portion To the discharge section The guide member, as well as interposed between the second rotary blade adjacent slitter, is characterized in that the attachment portion is fixed to the housing.

  In this case, the guide member bends one side portion of a flat plate having a penetrating portion that can penetrate the shaft of the second slitter and a notch portion that continues upward from the penetrating portion. In addition to constituting the mounting portion, a guide portion may be formed at the edge of the other side portion that is continuous from the cut-out upper end portion to direct chips of the paper downward.

  In the present invention, a plurality of rotations may be performed by holding a predetermined interval in the axial direction on each of a pair of shafts arranged in an axial direction in a direction orthogonal to the paper conveyance direction with a paper conveyance path interposed therebetween. The first and second slitters are formed by arranging the blades, and the peripheral edges of the rotating blades opposed to each other in the first and second slitters rotate while sliding to each other along the paper transport direction. In a slitter unit for a card cutting machine that is housed in a housing, a slitter mechanism that can cut the slitter mechanism is provided. An attachment portion to the housing is formed by bending one side portion of a flat plate having a notch portion continuous upward, and the sheet is formed at the other side edge portion that continues downward from the notch portion. Cut off A guide member for directing debris to the discharge unit, with interposed through the notch between rotating blades adjacent the slitter, is characterized in that the attachment portion is fixed to the housing.

The card cutting machine according to claim 1 is for cutting the paper in the conveying direction by the rotary blades arranged in the axial direction of the shaft. When the interval between the rotary blades is narrow, the cut paper (that is, (Strip-shaped chips) are likely to be caught between the rotary blades, and a guide member for smoothly guiding the chips to the discharge portion is continuous with the penetrating portion that can penetrate the shaft of the second slitter. Since the flat plate portion having the cutout portion is used, the guide member is fixed to the housing through the attachment portion after being inserted through the shaft of the second slitter through the cutout portion. Can be easily attached to the shaft.
For this reason, after assembling the second slitter in the housing, the guide member can be attached between the rotary blades, and the workability during manufacturing is improved. Further, when the guide member is replaced or repaired, it is not necessary to disassemble and remove the second slitter, so that workability is improved.
In addition, since the mounting portion extending in the direction perpendicular to the flat plate portion of the guide member is provided, the second shaft is attached to the housing via the guide member by solidifying the mounting portion on the inner wall surface of the housing. It becomes a state. Thereby, the stability of the second shaft is improved.

The card cutter according to claim 2 is configured to fold a flat plate having a penetrating part capable of penetrating the shaft of the second slitter and a cutout part continuous to the penetrating part, thereby to the casing. Since the mounting portion is configured and the guide portion is formed at the other side edge portion continuous from the notch portion, the guide member can be easily manufactured.
A slitter unit for a card cutter according to a third aspect of the present invention includes a penetrating portion capable of penetrating a shaft of the second slitter with a guide member for guiding the paper chips cut by the rotary blade to the discharge portion. And it formed by bending one side part of the flat plate which has a notch continuous with it. Thereby, the bent part can be used as a mounting part to the housing, and the other side edge part continuing downward from the notch part can be used as a guide part for directing chips to the discharge part.

When attaching such a guide member, it is attached to the shaft of the second slitter assembled in the slitter unit so that the penetrating portion is mounted through the notch portion. If it is bent so as to be positioned on the wall surface of the housing, it can be easily assembled in the housing by screwing or the like.
Thus, since only the guide member can be attached to and detached from the second rotary blade in a state where the second rotary blade is attached to a predetermined position of the shaft, the second slitter can be further disassembled without disassembling the second slitter. The guide member can be attached or exchanged without removing the slitter 2 from the housing, and the workability during manufacturing and repair is improved.
In addition, since the mounting portion extending in the direction perpendicular to the flat plate portion of the guide member is provided, the second shaft is attached to the housing via the guide member by solidifying the mounting portion on the inner wall surface of the housing. It becomes a state. Thereby, the stability of the second shaft is improved.

FIG. 1 is a perspective view showing a card cutter 100 according to an embodiment of the present invention.
This card cutting machine 100 cuts a standard size paper 3 such as A4 size or B4 size printed on a card into a predetermined card size, and discharges each cut card together with a blank portion. Yes, as shown in FIG. 2, created by a transport unit 5 for feeding sheets 3 one by one from the paper feed tray 4, a cutting unit 6 for cutting the sheet 3 into a predetermined card size, and a cutting unit 6. A card discharge unit 7 for discharging a plurality of cards is provided on a paper transport path 8 in sequence. The cutting unit 6 includes a cutter mechanism 9 for cutting the paper 3 in a direction (lateral direction) orthogonal to the transport direction, and a slitter for cutting in a direction along the transport direction (that is, the vertical direction). Mechanism 10.

The conveying unit 5 is configured to take out the sheets 3 stacked on the sheet feeding tray 4 one by one by a pickup roller 51 disposed on the downstream side and convey the sheets 3 to the sheet feeding roller 52. Is done.
The paper feed roller 52 is disposed in pressure contact with the double feed prevention pad 53, and when the card paper 3 conveyed to the paper feed roller 52 is conveyed in a state where two sheets overlap each other, the frictional force is reduced. Due to the difference, only one sheet is conveyed between the first conveyance roller 54 and the conveyance control roller 55 on the downstream side.

A first detection sensor S1 is disposed between the paper feed roller 52 and the transport roller 54, and the cutting information on the card paper 3 is detected.
In other words, the transported paper 3 is marked with a desired layout by the card printing system, but as shown in FIG. 3, the margin 3 32 other than the card area 31 corresponding to the card size is displayed. A mark 33 indicating information relating to the state in which the paper 3 is cut (that is, cutting information relating to the interval between the cutting lines) is also displayed together with the card printing. When the first sensor S1 detects the mark 33 indicating the cutting information, the first conveyance roller 54 and the conveyance control roller 55 are arranged so as to be cut in the horizontal direction according to the size of the card to be created. The timing for feeding the sheet to the cutter mechanism 9 is controlled.

  On the downstream side of the first transport roller 54 and the transport control roller 55, a second sensor S2 for detecting that the leading end of the card paper 3 in the transport direction has reached the reference position is disposed. The first transport roller 54 and the transport control roller 55 are rotated by a signal from the second sensor. The rotation of these rollers 54 and 55 is driven by a stepping motor set so that the card paper 3 can be intermittently conveyed for each predetermined conveyance amount. By such intermittent conveyance, the cutting positions (L1, L2,...) On the sheet 3 are temporarily stopped at the position where the cutter mechanism 9 exists.

The cutter mechanism 9 is for cutting the paper 3 in the lateral direction, and includes a pair of upper and lower cutting blades 9a and 9b extending in a direction orthogonal to the transport direction. The card paper 3 intermittently conveyed by the first conveyance roller 54 and the conveyance control roller 55 is cut in a direction orthogonal to the conveyance direction by cutting blades 9a and 9b that are driven in synchronization with the intermittent drive control. The chips of the paper cut in the lateral direction are discharged to a waste box 70 disposed below through a gap between conveyance rollers 56 and 57 described later.
The cutting blades 9a and 9b may be configured such that one cutting blade moves up and down relative to the other cutting blade and the other cutting blade is fixed, or both move up and down. Also good.

A transport roller group such as a second transport roller 56 and a third transport roller 57 is provided downstream of the cutter mechanism 9.
The transport rollers 56 and 57 are respectively paired up and down across the transport path 8, and as shown in FIG. 1, the upper rollers 56 'and 57' are rotatable on the lower surface of the lid 50 with a handle. Is attached. When a paper jam occurs during conveyance, the paper can be removed by lifting the handle and removing the lid 50.
A third sensor S3 is disposed between the second conveyance roller 56 and the third conveyance roller 57, and the sheet 3 conveyed by the second conveyance roller 56 (that is, after being cut in the horizontal direction by the cutter mechanism 9). ) In the state of). The timing at which the third conveyance roller 57 conveys the sheet 3 to the slitter mechanism 10 is controlled by a signal from the third sensor S3.

A slitter mechanism 10 for cutting the paper in the vertical direction is disposed downstream of the transport roller group.
The slitter mechanism 10 includes upper and lower two slitters (1, 2) and a drive unit for driving the slitter, and is provided as a slitter unit accommodated in the housing 40. A plurality of slitter units corresponding to the sheet cutting mode are prepared, and a unit corresponding to the card layout is appropriately selected and assembled into the card cutting machine 100 for use.
Hereinafter, the configuration of the slitter unit according to the embodiment of the present invention will be described with reference to FIGS. 4 and 5.

The slitter mechanism 10 includes a pair of upper and lower slitters 1 and 2, and these slitters 1 and 2 are pivotally supported on the side wall surface of the housing 40.
As shown in FIG. 6, these slitters 1, 2 are provided with disc-shaped rotary blades 12, 22 at predetermined positions of shafts 11, 21 arranged in the axial direction in a direction orthogonal to the conveyance direction of the sheet 3. Configured.

The first slitter 1 positioned above has a plurality of rotary blades 12 in the axial direction of the first shaft 11 while maintaining a predetermined interval. For example, in the slitter unit for cutting the paper 3 in the layout shown in FIG. 3, a thick blade for cutting the margin 32 at the center of the paper at the center of the shaft 11 (thick blade 12a for dropping a medium dove). A thick blade for cutting the margins 34 on both sides of the paper (a thick blade 12b for end dropping) is disposed at both ends of the shaft 11.
The thick blade 12a for dropping the middle dove has a cutting edge on both sides. Only the central side surface of the thick blade 12b for end dropping is a blade surface.

The second slitter 2 positioned below is also configured by arranging a plurality of rotary blades 12 while maintaining a predetermined interval in the axial direction of the second shaft 21. In this case, two thin blades 22 a and 22 b for dropping the middle dove are disposed in the center of the shaft 21 so as to correspond to the rotary blades 12 of the first slitter 1. A thin blade 22c for dropping is provided.
Both side surfaces of the thick blade 12a for dropping the middle dove in the first slitter 1 are in contact with the two thin blades 22a and 22b at the center of the second slitter 2 at the peripheral edge of each surface.

The shafts 11 and 21 of these two slitters 1 and 2 are rotated in opposite directions with the conveyance path 8 of the paper 3 interposed therebetween, and the paper 3 is cut in the vertical direction by the cooperation of the rotary blades 12 and 22. Is done.
At this time, the thick blade 12 of the first slitter 1 is pivotally attached to the shaft 11 and is rotated integrally with the shaft 11.

On the other hand, the thin blades 22a, 22b, 22c of the second slitter 2 are urged by the springs 24 toward the corresponding thick blades 12a, 12b. The second slitter 2 is also rotated integrally with the shaft 21 via the boss 27, but can be moved only in the axial direction by the pressing force of the spring 24.
The thick blade 12b for end dropping of the first slitter 1 is a cylindrical rotary blade, and is in contact with the thin blade 22c of the second slitter 2 at the peripheral edge of the blade surface provided on the inner side, and the outer peripheral surface. In FIG. 5, the roller 29 for preventing misalignment is pressed against both ends of the shaft 21 of the second slitter 2.

The misalignment prevention roller 29 is for preventing the sheet 3 from being displaced when being cut by the rotary blades 12 and 22, and is a roller 29 made of an elastic member such as rubber. The side edge portion of the paper 3 is held by the roller 29 for preventing misalignment and the cylindrical peripheral surface of the thick blade 12 of the first slitter 1 so that a constant tension is applied over the entire width direction of the paper. Can affect. In particular, since the surface of the paper being conveyed can always be pressed with a constant pressure from the cylindrical surface of the roller, cutting can be performed while applying tension to the paper 3 in a direction perpendicular to the cutting direction.
As a result, there is no deflection at the edge of the sheet, so that the straightness of the cutting line is maintained.

Further, by disposing the wide pressing rollers 18 and 28 between the rotary blades 12 and 22 in the respective shafts 11 and 12, the sheet 3 in a state of being cut in the horizontal direction is not separated, and the vertical direction is maintained. The cutting position is maintained.
Gears 15 and 25 are attached to end portions of the shafts 11 and 21 of the first slitter 1 and the second slitter 2 and mesh with each other. When the first slitter 1 is rotated by a motor (not shown), the second slitter 2 is rotated in the reverse direction.

In such a second slitter 2, the guide member 23 is disposed between the two rotary blades (thin blades 22 a and 22 b) for dropping the center.
The guide member 23 is for preventing the cut chips after being cut between the blades from turning around with the rotation of the shaft. As shown in FIG. A through portion 61 is provided in the center, and a cutout portion 62 is provided so as to continue upward from the through portion 61.
And the attachment part 63 for attaching to the housing of a slitter unit is provided in the orthogonal | vertical direction from the flat plate part 60. As shown in FIG. A guide portion 64 for directing paper chips toward the discharge portion 7 is formed at the peripheral edge opposite to the attachment portion 63.

The guide portion 64 has a thickness that can be inserted between two adjacent thin blades 22a and 22b.
The penetrating portion 61 of the guide member 23 is designed to have an inner diameter M slightly larger than the shaft diameter so that the shaft 21 of the second slitter 2 can be penetrated. The distance N connecting both ends of the notch 62 is designed to be slightly larger than the shaft diameter so that it can be fitted into the shaft from a direction orthogonal to the axial direction.
In the present embodiment, the inner diameter M of the penetrating portion 61 is 15 m and the distance N between both ends of the notch 62 is 14 mm with respect to the shaft diameter of 12 mm.

The length from the center of the penetrating part 61 to the upper edge part (that is, the upper end part of the guide part 64) is set smaller than the radius of the second rotary blade 22 (that is, the upper end part is set to be longer than the peripheral edge of the rotary blade 22). By positioning it on the shaft 21 side, the chips of the paper 3 are prevented from turning around with the rotation of the blade 22.
That is, the notch portion 62 is designed so that the upper end of the guide portion 64 is located at a point where the conveyed paper 3 is cut or slightly on the transport destination side from the cutting point. A guide portion 64 is formed so as to draw a curve along the rotation direction and go from the tip on the conveyance destination side to the lower side of the second rotary blade 22 (see FIG. 5).
By designing the guide member 23 in this way, there is no room for the cut paper (that is, strip-shaped chips) to stay between the thin blades 22a and 22b, and the chips are pressed into the shaft 21. Can be prevented.

As shown in FIG. 8, such a guide member 23 is manufactured by bending one side portion of a flat plate 60 ′ having a through portion 61 and a notch portion 62 that is continuous upward from the through portion 61. can do. An attachment portion 63 to the casing is formed by the bent portion, and a guide portion 64 for directing chips toward the discharge portion 7 is provided at the other side edge portion that continues downward from the notch portion 62. It is formed.
After the second slitter 2 is assembled to the housing 40, the guide member 23 is fitted between the two thin blades 22a and 22b for dove dropping and is mounted on the shaft 21. And it fixes to the housing 40 via the attaching part 63. FIG.

After assembling the first and second slitters 1 and 2, the slitter unit according to this embodiment is formed by covering the downstream side surface of the housing 40 with the lid member 41 and the bottom member 42.
A discharge roller 58 for conveying the cut paper (that is, a plurality of cards and chips) to the card discharge unit 7 attached to the outer wall surface of the card cutting machine 100 is provided downstream of the slitter unit. It is done.
The card discharge unit 7 has a tray having a width corresponding to the size of the cut card, and the discharged cards are stacked in the tray.

A state where a card is created by the card cutting machine having the above configuration will be described.
First, the paper 3 printed on the card is supplied to the paper feed tray 4 and the drive switch is turned on. Then, the paper is taken out one by one by the paper feed rollers 51 and 52 and conveyed to the cutter mechanism 9.
During the conveyance, information relating to the sheet and cutting mode is obtained from the mark 33 displayed on the sheet 3, and the drive motor is controlled so that the conveyance control roller 55 is rotated in accordance with the mode (see FIG. 3). In this case, it stops at the first cutting position L1, and cuts with the cutting blades 9a and 9b. Then, the card is conveyed by an amount corresponding to the length of the card in the vertical direction, and the next cutting is performed by the cutting blades 9a and 9b. In this manner, the sheet 3 is conveyed to a predetermined position (L1, L2, L3, L4, L5, L6), stopped, and sequentially cut, whereby the horizontal cutting of the sheet 3 is completed.

Thereafter, the slitter mechanism 10 cuts the card region 31 and the blank portions 32 and 34 along the transport direction. The cut card region 31 is discharged to the card discharge unit 7, and the blank portions 32 and 34 are It is discharged to the chip discharge unit 70. At this time, the blank portion 32 that has been cut off is smoothly guided to the discharge portion 70 by the guide member 23 provided between the thin blades 22a and 22b for dropping, so that the blank portion 32 is not sandwiched between the rotary blades.
In such a card cutting machine 100, when the maintenance of the guide member 23 is performed, the slitter unit is taken out from the card cutting machine 100, the cover part 42 covering the bottom surface of the housing 40 is removed, and then the attachment part 63 is used. The guide member 23 is removed (see FIG. 4). Since the guide member 23 can be attached and detached without removing the second slitter 2 from the housing 40 and disassembling, the workability in manufacturing and repair is improved.

Although the card cutting machine according to the present embodiment is configured to cut the paper in the vertical direction and the horizontal direction, the card cutting machine may cut the paper only in the vertical direction (that is, a machine that does not have a cutter mechanism). Good.
Further, the slitter mechanism may be housed in one casing together with a mechanism such as a transport mechanism or a cutter mechanism. In this case, the shape of the plate member 60 of the guide member 23 and the bent state for forming the attachment portion 63 are appropriately designed according to the attachment position of the second slitter 2.

For example, the attachment portion 63 of the guide member 23 may be attached to the bottom surface of the housing 40. Moreover, you may design the inclination state of guide part 64 'so that a chip | tip may be guide | induced to discharge part 70' provided in the specific position like guide member 23 'shown in FIG. In this case, the restricting plate 71 for restricting the chip conveying path is disposed at a position where the rotary blade 22 of the second slitter 2 is disposed so as to be guided in a direction different from the card conveying path 8. May be provided.
