When the solenoid 47 is turned off, the hook 46 rotates counterclockwise and comes off the protrusion 41c. In addition, by operating the handle 16, the sensor lever 36b
rotates counterclockwise to block the lower limit sensor 39 and at the same time lower the arm 42 against the upward biasing force, the left side of the lever 41 descends and the lock provided on the lever 41 The lever 44 is released from the piece 41e, and the lever 4
4, the upper conveyance roller 40b presses the lower conveyance roller 40a due to its own weight. In addition, sheet material 2
An entrance guide 49 (see FIG. 7) that limits the thickness of the bundle is pivoted by a pin 49a fixed to the device 1, and is suspended so as to be rotatable clockwise. In addition, 50 in FIG. 7 is a conveyance table provided adjacent to the downstream side of the die 10. Reference numeral 51 denotes a ring entrance guide for preventing scattering of the leading end of the bundle of sheet materials 2 being conveyed, and is suspended from a fixed pin 51a so as to be rotatable clockwise.

Next, the ring opening/closing means 7 will be explained with reference to FIG. 1 and FIGS. 3 to 5. An upper claw (upper support member) 52 that extends horizontally in a comb shape and whose tip is curved diagonally upward is guided vertically inside the side wall of the ring opening main body 7a to control the gear train 53. It is designed to be driven by a motor 55 via the motor 55. In addition, a large number of lower claws protrude obliquely upward and are arranged so that their tips are perpendicular to the conveying direction of the sheet material 2 (
A lower support member) 56 is driven by a motor 59 via a gear train 57. Further, when the link 6, which is a binding member made of plastic and has a plurality of horizontally curved claws curved in a substantially circular shape on one spine, is inserted into the upper claw 52, the ring The sensor lever 60, which rotates counterclockwise by the outer diameter of the ring 6, is biased and pivoted to rotate clockwise by its shaft 60a, and detects the ring 6 below the sensor lever 60. A plurality of ring sensors 61 that also detect the ring size are arranged in a row.

First, the operation of the automatic mode will be explained mainly with reference to the flowchart of FIG. First, the resin ring 6 (hereinafter referred to as resin ring) is attached to the upper support member 5 shown in FIGS.
Set it on top of 2. In the initial state, the ring sensor lever 60 is pressed against the upper support member 52 by the elastic member, but by setting the resin link 6 on the upper support member 52, the ring sensor lever 60 is moved counterclockwise in FIGS. 3 and 4. The lower end blocks the ring sensors 61a and 6lb, and detects the presence or absence of the resin ring 6. Ring sensor 61a
, 6lb is composed of multiple sensors, and each sensor's ON
The size of the resin link 6 is recognized by the combination of /OFF.

The size of the resin ring 6 is determined by the size of the sheet materials 2 that you wish to stitch together.
Since several types are available depending on the thickness of the hole, the numerical value to be set in the next step is determined by detecting the link size, thereby achieving automation after drilling.

Insert the sheet material 2 from the operation side (left side in FIG. 1). At this time, as shown in FIG. 7, the perforation position of the sheet material 2 is defined by abutting the sheet material 2 against the stopper 13a. Further, the tip of the sheet material 2 is prevented from being lifted upward by a sheet material regulating means (entering guide) 49.

When stitching the sheet materials 2, the sheet materials 2 are inserted in eight directions indicated by arrows shown in FIG. 3(a). At this time, the sheet material regulating means 49 hits the regulating stopper 49b due to its own weight and stops, thereby keeping the gap X between the sheet material regulating means 49 and the die 10 constant. This gap X is defined by the perforation capacity, and sheet material 2 having a thickness greater than this gap X is not inserted by the sheet material regulating means 49, thereby preventing poor perforation or poor stitching.

Then, the sheet material 2 that has undergone the perforation and stitching operations is pulled out in the direction of arrow B in FIG. 7(b). At this time, the resin ring 6 used for stitching is attached to the tip of the sheet material 2, and the thickness of the sheet material 2 is increased, but the sheet material regulation stage 49 is as shown in FIG. 7(b). As shown by the solid line, since the structure is such that it can be retracted in a clockwise direction, the sheet material 2 can be pulled out without any hindrance to the pulling-out operation, and the work is completed.

As described above, the thickness of the sheet material 2 is controlled by the sheet material regulating means 4.
9, stable stitching work can be performed without causing problems such as poor punching or poor stitching due to poor punching. Further, by placing the sheet material 2 on the mounting table 9, the sensor lever 11 rotates and blocks the sheet sensor 13 to detect the presence or absence of the sheet material 2.

It is necessary for the operator to punch holes at appropriate positions in the sheet material 2 depending on the size of the resin ring 6 to be used. That is, by setting the resin ring 6 on the upper support member 52 of the stitching section, the ring sensor lever 60 is activated.
The size of the resin ring 6 is recognized by ring sensors 61a and 6lb. Then, in order to define an appropriate perforation position in the sheet material 2, the stoppers 13a and 13b are interlocked.

In this embodiment, two types of drilling positions are used, and either of the solenoids 15a and 15b is selected based on the signal after six resin rings are set, and one of the unnecessary solenoids 15a and 15b is pulled down to form the sheet material 2. I'm trying to hit the nail on the head. Note that a plurality of stoppers 13a and 13b may be provided, and it goes without saying that they may be configured to be movable.

Next, the punching process will be explained. As shown in FIGS. 8 and 9, the bunch 20 has a guide 2 paired with the die 1o.
It is a manufacturing problem that the guides 22 and 23 each consist of three pieces.
Each may be composed of one sheet. These vertically independent horizontal formations are intended to enable the resin ring 6 to be pulled out to the entrance side in a state where it is bound to the sheet material 2 after the work is completed.

In order to perforate the sheet material 2 that has abutted against the stoppers 13a and 13b, the handle 16 is first pushed downward. The position of the handle 16 is detected by sensor levers 32a and 32b, an upper limit sensor 35, and a lower limit sensor 36, which rotate together with the handle. By pushing down the handle 16, the punch 20 is lowered and raised by a cam mechanism formed with the shaft 17, and the sheet material 2 is perforated.

In this embodiment, the upper conveying roller 40b and the lower conveying roller 40
A is arranged at intervals, and the pickup configuration is as shown in Fig. 10. This is because when inserting the sheet material 2 and hitting it against the stoppers 13a and 13b,
The upper conveyance roller 40b is in a retracted position from the conveyance path, and is lowered to the conveyance path in order to convey the sheet material 2 to the binding section after the punching operation is completed.

In this mechanism, by first pushing down the handle 16, the lower limit sensor lever 32b rotates, and the lower limit sensor 36
At the same time, the pickup arm 42 is pushed down.

As a result, the pickup lever 41, which is configured to be rotatable together with the big up arm 42, is pushed down.
The upper conveyance roller 40b descends under its own weight, and the lower conveyance roller 4
Together with 0a, the sheet material 2 is pressed down to enable stable conveyance. At this time, a pin 41c is fixed to the pickup lever 41 so that the pickup lever 41 does not return.
is configured to be held by a claw 46a at the tip of the lock arm 46.

After punching the sheet material 2, pull up the handle 16 and pull out the punch 20 from the sheet material 2. At this time, 1! of the punch 20 and the sheet material 2rrR! When the sheet material 2 is lifted by the J-rubbing and hits the guide 23 and then comes off, the sheet material 2 is pulled diagonally and shifts from the position determined by the stoppers 13a and 13b. The sheet is held down by a sheet holding mechanism shown in FIG.

In the initial state, this mechanism is pressed against the guide 23 by the spring 27, but it descends as the handle is operated and presses the sheet material 2 to prevent the sheet material 2 from shifting during drilling. In order to help the punch 20 come off, the punch 20 is prevented from returning by the lock plate 29, and the punch 20
The cam mechanism of the release plate 31 returns to the initial state at the time when all the parts have come out of the sheet material 2. Next, when the upper limit sensor 35 detects the completion of drilling, the solenoids 15a and 15b lower one of the stoppers 13a and 13b, and then the conveyance motor 37
The lower conveying roller 4 is driven by the belt and gear drive.
0a, the conveyance upper roller 40b is simultaneously driven and the sheet material 2
transport. Although the conveying rollers 40a and 4ob can convey the sheet material 2 by driving them either up or down, vertical driving is effective in increasing the conveyance accuracy when a large number of sheets are being conveyed. The transported sheet material 2 is sent to the ring opening/closing section via the transport table 50. At this time, sheet material 2
In order to prevent curling and disorder of the tip of the sheet material 2 and to ensure more reliable binding of the sheet material 2 to the resin link 6, a link entrance regulating plate 51 is provided on the conveyance path to regulate the gap.

The perforation and conveyance of the sheet material 2 have been explained above, and next, the ring opening will be explained.

The outline of the ring opening/closing part is as shown in the right half of Figure 1.
It consists of an upper support member 52, a lower support member 56, gear trains 53 and 57 for driving each, motors 55 and 59, and a sensor section that detects the size of the resin ring 6.

As mentioned above, by sandwiching the resin ring 6 between the upper support member 52 and the ring sensor lever 60,
The size of the resin ring 6 to be used is recognized and the opening amount of the resin ring 6 is determined. At this time, the resin ring 6 used
The opening amount varies depending on the upper support member 52.
Although the resin link 6 is opened by the lower support member 56 and the lower support member 56, the amount of movement of both members is also different.

The opening operation of the resin ring 6 will be explained with reference to FIGS. 4 and 6. The set resin ring 6 is attached to the upper support member 52
It is supported by the ring sensor lever and is sandwiched between the ring sensor levers. A key-shaped lower support member 56 is moved in parallel to the inside of the resin ring 6 by a cam mechanism (not shown) as shown in FIG. Thereafter, the upper support member 52 and the lower support member 56 are each moved to a specified opening amount to open the opening. When the lower support member 56 is lowered, FIGS. 18(a) and 18(b)
), the ring sensor lever 60 and the sensor plate 83 to which the ring sensors 61a and 6lb are attached are pushed down, and the ring sensor lever 60, which had been protruding onto the sheet material conveyance path, is removed from the conveyance path. We will have to evacuate. Therefore, stable stitching work can be performed without the ring sensor lever 100 interfering with the conveyance of the sheet material 2 being conveyed. In this embodiment, the upper limit sensor 35 of the handle 16 is configured to perform the opening operation at the same time as the punching operation ends, but the timing of this opening is until the sheet material 2 being conveyed reaches a specified position. You can do anything you want between. This open state is shown in FIG. 3, but the opening amount 72 of the resin ring 6 and the position 73 of the ring tip are within the range of not exceeding the elastic limit since the resin ring 6 is an elastic member. This configuration is such that the position at which a larger number of sheet materials 2 can be stitched is empirically set by collecting various data, and the optimum setting is made without hesitation each time the operator sets the resin ring 6. Since the conveyed sheet material 2 is perforated at a position determined by the ring size, the sheet material 2 is fed until the perforated position is approximately at the center of the ring tip position 73. When the conveyance operation is completed, the upper support member 52 and the lower support member 56 move in the same direction so that the daily opening amount of the resin ring 6 does not change, and the tip of the resin ring 6 penetrates the perforated portion of the sheet material 2. 5, the upper support member 52 and the lower support member 56 are moved in the direction in which they are closed. Finally, the regulating member 71 and the ring entrance regulating plate 51 are configured to be rotatable, so that the regulating member 71 and the ring entrance regulating plate 51 do not interfere with the pulling operation of the sheet material 2. No. The operations of each of the above steps are displayed on the operation panel to provide support to the operator in sequence and to enable visual confirmation up to the final step. A block diagram of the control system is shown in Figure 3. Next, the operation in manual mode will be explained using FIG. 1 and FIGS. 14 to 17. Normally, automatic mode can operate when the number of sheets or the thickness of sheet material 2 is less than the perforation capacity. However, when binding the number of sheets that exceeds the perforation capacity, do not use the automatic mode, but divide the sheet material 2 into several sheets that are below the perforation capacity, perform the perforation work, and then attach the resin ring 6 to the sheet material 2. It will be stitched together. Also, when you want to add or replace sheet materials 2 to sheets 2 that have been bound together in advance, you will need to use the manual mode instead of the automatic mode. To stitch the sheet materials 2 in manual mode, first,
The stitching means R shown in FIG. 1 is rotated clockwise about the fulcrum 75 and held in the position shown in FIG. 16 by a fixed method not shown. At this time, when the automatic/manual changeover switch 76 attached to the stitching means R is rotated, it is turned OFF and the manual mode is detected. Then, the auxiliary guide cover 79 attached to the cover 77 of the automatic sheet material binding device B is also rotated counterclockwise to the position shown in FIG. 3. In the automatic mode, this auxiliary guide cover 79 is held in the position shown in FIG. 1 in conjunction with the cover (not shown) of the binding means R, and in the manual mode,
It is moved to the position shown in FIG. 16 by an elastic member (not shown).

Next, the actual work will be explained.

First, the resin links 6 used for stitching are attached to the upper support member 5.
2 and the lower support member 56. The sheet material 2 to be bound is divided into several parts whose perforation capacity is below, and the perforation work is performed in the manner described above. Then, insert the perforated part into the opened claw part 6a of the resin ring 6 at any time.
After inserting the necessary sheet material 2, the resin link 6 is closed and the sheet material 2 is pulled out to complete the binding operation. When inserting the sheet material 2 into the resin ring 6, the auxiliary guide cover 79 serves as a guide and a mounting base for the sheet material 2, as shown in FIG. Work can be done easily. Since the link sensors 61a and 6lb are attached to the sheet material automatic stitching device, they cannot be used when the stitching means R rotates and enters the manual mode.

Since several types of resin rings 6 are actually used depending on the size of the diameter, the opening amount is determined by the operator.

At this time, since the opening amount for the resin ring 6 is stored in advance in the device, the operator sets the resin ring 6 on the upper support member 52 and then presses the link opening button 80 shown in FIG. The desired opening amount of the resin ring 6 can be obtained by pressing the button a number of times. When the insertion work is finished, the ring close button 81 is pressed to perform a closing operation and finish the work.

Also, when adding or replacing the sheet material 2, as shown in FIG. 15, the upper support member 5
The sheet material 2 is set so as to be placed under the sheet material 2, and the resin ring 6 is opened and closed and the sheet material 2 is punched in the same manner as described above to add and replace the sheet material 2.

In this embodiment, as the lower support member 56 of the stitching means is lowered, the ring sensor lever 60 and the sensor metal plate 83 to which the ring sensors 61a and 6lb are attached are lowered and evacuated from the sheet conveyance path. However, the ring sensor lever 60 may be retracted from the sheet conveyance path using a solenoid or the like independently of the operation of the lower support member 56.

(G) Effects of the Invention As explained above, according to the present invention, after detecting the presence or absence and size of the resin link, the ring sensor lever is retracted from the conveyance path of the sheet material, so that the sheet being conveyed is Stable stitching work can be performed without interfering with the materials.
