And re-binding means for re-binding by the binding means by omitting the operation of punching the sheet material by the punching means after detecting the conveyance failure of the sheet material.

In addition, after the detecting means detects the conveyance failure of the sheet material, when it is determined that the perforating operation of the perforating means is not completed,
The present invention is characterized in that a perforating operation determining means for re-binding the sheet material is provided, and the perforating operation determining means is the re-binding operation means.

The binding means is formed to be operable in a manual mode, a binding member opening / closing command means for instructing opening / closing of the binding member is provided, and a manual mode determination means for determining a manual mode is provided; After detecting a conveyance failure of the sheet material, when the manual mode determination unit determines that the manual mode is not set, the binding member opening / closing command unit is replaced with the re-binding operation unit.

(E) Operation Based on the above configuration, after the sheet material is perforated by the perforating means, the sheet material is conveyed to the binding means by the conveying means, and the sheet material is automatically bound by the binding member. At this time, if the conveyed sheet material is detected as a conveyance failure by the detection means, after this detection, the perforation operation of the perforation means is omitted, and the re-binding operation means is operated to operate the re-stitching operation means. The sheet material is re-bound by a binding unit.

Further, after detecting the conveyance failure of the sheet material by the detecting means, if the perforating operation of the perforating means is not completed, a signal is issued from the perforating operation determining means, and the conveying means and the binding means are operated, and the sheet material is operated.

The motor 8 that drives the a and 40b may be reversed to automatically pull out the bound sheet material 2.

By doing so, it is possible to improve labor saving and time saving of the binding operation.

Next, the operation of the manual mode will be described. When the main body 7a is tilted and fixed as shown in FIG.
Is issued, and the control unit 79 that has received the ON signal switches the control system to the manual mode. In this mode, if the single punching capability of the punch 17 or the like is insufficient with respect to the binding capability of the ring 6, punching is performed many times and additional binding is required.
In addition, there is a case where replacement or the like is desired to be performed, and this mode is used when there is a problem with only the automatic mode.

In the manual mode, the automatic conveyance of the sheet material 2 is not performed.
It is operated by the ring opening button 86 and the ring opening button 87.

If you want to add or replace sheet material 2, Fig. 16 (a)
When the sheet material 2 is set below the upper claw 52 and the ring opening button 86 is operated as shown in FIG. 16 (b), the sheet material 2 can be freely removed, and the addition of the sheet material 2 is performed. Replacement can be freely performed.

When the perforated sheet material 2 is conveyed onto the conveyance table 50, when the sensor 90 does not detect the sheet material 2 within a predetermined time,
It is said that a delay jam (transport failure) has occurred.

In step S4 of FIG. 2A, the operation shown in FIG. 2B starts from the step of conveying the sheet material. In step K1, when the sensor 90 detects within a predetermined time, the process proceeds to step K2, where normal binding is performed and the operation is completed.

However, if the sensor 90 cannot detect the sheet material 2 within a predetermined time, the process proceeds to step K3, JAM is displayed on the display unit 80, and the ring 6 is closed by the ring motors 5,59.
Then, the operator pulls out the sheet material 2. Next, the process proceeds to step K4, and when the ring 6 is detected by the sensor 61 and the sheet material 2 is detected by the sensor 11, the process proceeds to step K5,
When the stopper 12a or 12b corresponding to the size of the ring 6 is raised and the re-binding button 89 is turned on, the process proceeds to Step K6,
The punching operation is omitted, the stopper 12a or 12b is lowered, the ring 6 is opened, and the flow returns to the flow for transporting and rebinding the sheet material 2. Hereinafter, the operation described above is repeated. If the ring 6 cannot be detected in step K4, it is determined that the worker has stopped working halfway, and the work ends.

 Next, another embodiment will be described.

When the sheet material 2 is not detected by the sensor 90 within a predetermined time (in the case of a conveyance failure of the sheet material 2), the handle 16
Is slightly lowered and then raised, the transport unit 5 and the ring opening / closing unit 7 are automatically turned on by a signal that the upper limit sensor 37 turns off and then turns on (the signal of the lower limit sensor 39 is determined to be uncompleted). When activated, the re-binding operation can be performed.

By doing so, the re-binding button 89 becomes unnecessary, and the apparatus 1 can be simplified.

 Next, still another embodiment will be described.

After the sheet 90 is detected as a conveyance failure by the sensor 90, the detection signal is used to switch the ring open / close buttons 86 and 87 in the manual mode so that the re-binding operation can be performed in the automatic mode. Can work.

By doing so, the re-binding button 89 can be omitted as in the other embodiments.

(G) Effects of the Invention As described above, according to the present invention, after the conveyed sheet material is detected as a conveyance failure by the detecting means, the perforating operation of the perforating means is omitted, and the re-binding operation means is used. Since the sheet material can be re-bound, it is possible to prevent the perforated portion from being dubbed in the sheet material and the perforated portion from becoming excessively large.
Only by operating the re-binding operation means, the rest can be automatically re-bound, and labor of the operator can be greatly reduced.

Further, the re-binding operation means can be omitted by the punching operation determination means or the binding member opening / closing instruction means in the manual mode, so that the apparatus can be simplified and the cost can be reduced.
