[explanation of main control system]

The main CD-ROM drive motor 42 of drive system shown in Figure 5, the left and right directions of pin tractor 21 move rotary solenoid 125 that the CD-ROM drive motor 55 of usefulness, top shown in Figure 22 carry the lifting of rubber rollers 76a, 77a to use, blank detecting sensor 79 shown in Figure 4 and operating portion 8 shown in Figure 1 and link to each other with the electric property of control device, the input signal of importing according to the operation of each action button by operating portion 8 and from form the various input signals such as input signal of paper detection sensor 79 carry out the control of each CD- ROM drive motor 42,55 and rotary solenoid 125.In addition, in control device also input have from the anglec of rotation on the driving shaft 34 that is arranged on main CD-ROM drive motor 42, pin tractor 21 etc. and the signal of rotation amount detecting sensor.

In Fig. 5, in continuous cutting operation, the main CD-ROM drive motor 42 of drive system rotates all the time, utilize the rotary driving force of main CD-ROM drive motor 42, wait the bottom of the front and back that drive severing portion 17 all the time to carry rubber rollers 76b, 77b, top to carry the band conveying mechanism 12 of rubber rollers 76a, 77a, pin tractor 21, end cut-out portion 16 and paper receiving portion 7 by synchronous belt formula transmission mechanism 41, synchronous belt (with reference to Figure 19) and transmission mechanism 168,169 (with reference to Fig. 3).In addition, chopping portion 20 also is driven.In severing portion 17, as mentioned above, conveying rubber rollers 77a, the 77b of rear side is to be rotated greater than the conveying rubber rollers 76a of front side, the speed of 76b.

On the other hand, the top of Figure 22 carries rotary solenoid 125 that the lifting of rubber rollers 76a, 77a uses according to moving in the following moment from the blank detection signal of the blank detecting sensor 79 of Fig. 4, the front end and the terminal detection of for example blank.

Promptly, in Fig. 4, in cutting operation, rubber rollers 76a is carried on top, common and the bottom conveying rubber rollers 76b of 77a, it is relative (for example gap about 0.8mm) that the 77b sky is opened a little gap, when blank detecting sensor 79 detects front end on the throughput direction F of the continuous forms that transports from pin tractor 21, behind the counting of regulation, or after the driving wheel 27 that makes pin tractor 21 has rotated the regulation rotation amount, inferring that continuous forms N comes the moment on the assigned position, lifting drives the rotary solenoid 125 rotation predetermined angulars of usefulness, make the top of front and back carry rubber rollers 76a by the cam effect, 77a descends, and utilizes the conveying rubber rollers 76a of the front and back in the rotation, 76b, 77a, 77b is respectively from clamping continuous forms N up and down.The assigned position that is fit to the described continuous forms N of severing is that the eyelet M1 of continuous forms N comes welded part 78 position of side after a while.Therefore, when utilizing conveying rubber rollers 76a, 76b, 77a, 77b with the continuous forms N clamping on the assigned position, because the peripheral speed of conveying rubber rollers 77a, the 77b of rear side is greater than conveying rubber rollers 76a, the 76b of front side, therefore continuous forms N is subjected to big tension force on fore-and-aft direction, thus near the fracture of the eyelet M1 place welded part 78.Then, if blank detecting sensor 79 detects the end on the throughput direction F of the format independent paper that has ruptured, then the lifting rotary solenoid 125 that drives usefulness rotates predetermined angular once more, removes the cam effect.Thus, make top carry rubber rollers 76a, 77a to rise, make between conveying rubber rollers 76a up and down, 76b, 77a, the 77b open.Under this state, utilize pin tractor 21 that continuous forms N is delivered on the assigned position once more.

In a word, the conveying rubber rollers 76a of pin tractor 21 and front and back, 76b, 77a, 77b rotate all the time, by the conveying rubber rollers 76a before and after switching, 76b, 77a, 77b to the clamping (pushing) of blank with unclamp, with the continuous forms continuous cutting-off.

The of the present utility model various controls of the major control that will illustrate above will comprising are summarized as follows.

(1) top of automatically regulating severing portion 17 according to the adjusting of the transporting velocity of pin tractor 21 carry rubber rollers 76a, 77a lifting constantly, be blank clamping constantly and unclamp constantly.Corresponding to the various transporting velocities of pin tractor 21, after blank fracture, the eyelet M1 of the blank of back is arrived the moment datumization of suitable assigned position with respect to welded part 78 and be stored in the control device.In addition, when operation, utilizing operating portion 8 to set the occasion of the transporting velocity of pin tractor 21, reading best blank clamping in the data from be stored in control device and unclamp the moment, and automatically set described clamping constantly.Particularly, when the setting transporting velocity of pin tractor 21 accelerated, after fracture, the time that the blank of back is transferred rubber rollers 76a, 76b, 77a, 77b clamping became early.

(2) when the kind of severing continuous forms is the blank of bilayer or three-decker, promptly when the additional part blank (Japanese: パ one Star Paper) that carbon paper etc. arranged is ruptured, the load of carrying rubber rollers 76a, 76b, 77a, 77b to be subjected to increases, therefore, the rotating speed of main CD-ROM drive motor 42 descends, in order to make it get back to fixing speed, the decline of the rotating speed of main CD-ROM drive motor 42 is detected and it is fed back to main CD-ROM drive motor 42, thereby make the rotating speed of main CD-ROM drive motor 42 get back to the regulation rotating speed.Be not only the blank of bilayer or three layers, also carry out FEEDBACK CONTROL, so that (Japanese: use main ミ シ Application face) makes the rotating speed of main CD-ROM drive motor 42 maintain the regulation rotating speed by its thickness or main aperture eye face for the blank of individual layer.In addition, the rotating speed of main CD-ROM drive motor 42 is read by the encoder of the slit plectane 87 that has utilized Figure 18.

(3) can change the sensitivity of the blank detecting sensor 79 of Figure 23 according to the thickness of continuous forms.For example, operating portion 8 has " thin paper-standard paper " selector button, and the user manually selects.In addition, in when energising device, should not having blank, but if detected paper by blank detecting sensor 79, then may be to produce alarm owing to paperboard or sensor are dirty etc.Show that as alarm demonstration needs to take out blank or sensor is cleaned.

(4) position and the amount of feeding of measuring blank with encoder (slit plectane 57 etc.) on the driving shaft 34 of the pin tractor 21 that is arranged on Fig. 7 and the blank detecting sensor 79 that can detect the blank front end of Figure 23 carries out the severing moment, jam detection etc.For example, setting several feedings hole 301 or several inch from the blank front end in advance for, is that benchmark carries out with the blank front end all to each.

(5) when the high speed severing, skidding of continuous forms detected, when blank skids when having become big the control that severing speed is reduced.That is, has so-called AI fracture function.For example, the time blank amount of feeding (rotation amount of pin tractor 21) that is carved into till the end that blank detecting sensor 79 detects the blank that has ruptured from the conveying rubber rollers 77a of rear side, 77b clamping blank is detected, and the amount of skidding when blank is carried detects.Detecting when skidding, control main CD-ROM drive motor 42, transporting velocity is reduced.

(6) as the work pattern of device, can also only utilize the operation of end cut-out portion 16.That is, only with ear's 300 severings at the both ends, the left and right sides of continuous forms and discharge.

(7) left and right sides width of pin tractor 21 CD-ROM drive motor 55 that utilizes left and right sides width to move usefulness is regulated, but can be stored in the control device setting width.Thus, when the blank of severing same size next time, can automatically regulate the left and right sides width of pin tractor 21.

(8) as mentioned above, set the blank transporting velocity of the band conveying mechanism 12 of paper receiving portion 7 for blank transporting velocity less than pin tractor 21, thereby on paper receiving platform 7, format independent paper is carried with the squamous ground stacked state of part, and be deposited on the front surface of holding up guiding framework 13.

(9) when the blank that is supplied to finishes, after the end that detects post-rift last format independent paper from blank detecting sensor 9 has passed through the stipulated time, the band conveying mechanism 12 of paper receiving portion 7 is stopped.As the described stipulated time, be set at the required enough time on the guiding framework 13 of holding up is carried and be deposited in to last format independent paper from severing portion 17 at paper receiving platform 7.Thus, can reliably format independent paper be deposited in hold up the guiding framework 13 on, till the format independent paper to the last.

(10) number that can utilize operating portion 8 to import the feeding hole 301 that forms on the end of blank is set the severing size of continuous forms.As other establishing method, also available inchage is set the discontinuity size of blank.Therefore by the way, as mentioned above,, when making continuous forms, the amount in ten feeding holes 301 is set at the blank amount of feeding for example with 5 inches interval fracture because the spacing between the feeding hole 301 is 1/2 inch.

(11) as mentioned above, on operating portion 8, be provided with make pin tractor 21 with low speed just advance, the contrary button that advances.That is, when being set in continuous forms N on the device at the beginning, or when the paperboard state processing, or when the test severing, can manually taking time and set and carry out severing.

(12) amount to the chopping sheet of the chopping sheet containing box 5 of Fig. 1 detects, and when expiring, device is temporarily stopped.

(13) be stored in the control device and when calling, can automatically accelerate to the speed of described storage next time will going up once running speed.

(14) handle number if preestablish the needs of blank, then when the fracture of the blank that sets finishes, arresting stop automatically.

(15) rear side that can consider severing portion 17 carry lifting that the response of rubber rollers 77a, 77b comes rubber rollers 76a, 77a are carried in top constantly, be to control in the clamping or the moment of unclamping blank.Promptly, various transporting velocities corresponding to pin tractor 21, set, store by the moment that test in advance comes eyelet M1 to continuous forms N to come near the assigned position the rear of welded part 78, and read suitable lifting constantly based on the transporting velocity of the pin tractor of setting 21.

[effect]
