Paper cutting machine with control for program center

The invention "conquered itself on a paper cutting machine" in which the saddle is powered by an electric motor hydraulic system ocUdgi «is driven and carried out of automatically controlled Yorsehübsn of unequal size can evaluate adjustable switching points shut down with Ulfe

To carry out automatically controlled batchwise, Unequal feeds are in known paper cutting machines slit the üJräger of the saddle or with one with the Saddle moving measuring tape or similar adjustable countersunk connected »that work against fixed contact switches or stop cams. The positions of the adjustable stop saws determine the desired position of the saddle on the Sisoh and thus the length of the pile of paper, which is unequal wide strips are to be cut

The stops cause the control of the saddle drive elements, at the same time the automatic switching on and off of the cutting process

As Ansehläge are already! "Initiate ichtsshrankeni the case of interruption of the light beam & s switching process, known ·

In all known paper cutting machines have to General management of a program for cuts of unequal width (No program) slide-shaped stops, discs or the like · »

By using such magnetic sound carriers, for example in the form of audio tapes or commercially available wires, all that is required is "a" B with the visual spindle of the saddle, two reels or the like. Zn couple so that a sound carrier wound on one reel can unwind and wind on the second reel and vice versa, depending on whether the saddle is moved forwards or backwards. The magnetic sound carrier is running

past a magnetic head of a recording and playback device housed at any point so that the desired intersection of the saddle can be achieved when the device is switched to recording on the sound carrier by briefly pressing a button or the like. and a dadia? ah triggered impulse can apply frequency markings which, when the device is switched to playback, generate a pulse in the device, which is then amplified and used for control

This type of program editing control allows for a high degree of accuracy in the selection of the sound carrier because the sound carrier can be of any length and can be a multiple of the saddle path, with the running speed of the sound carrier then also being a multiple of the saddle speed. Am © Irequena marking on the son tape *. which represents a small, pnnlit-shaped magnetic field, thus runs through a longer path in the side unit than the saddle, so that the electrical motor has sufficient power. Still the Setsen of the saddle and its drive, and thus the accuracy of Sebnittlage in Terhältnis exerts (Sesöhwindigkeit of Eonträgers to that of the caliper can be increased.

On & ery5eichnung is a schematic embodiment a paper cutting machine with the invention Program editing control shown, and swar shows it

ig · 1 a longitudinal section through the 3? paper cutting edge ~ machine «*

According to the embodiment there is the paper cutter. ; machine in the usual way from a table 1 with longitudinal; the slot 2 through which the carrier 3 of the Yorschubsattels 4 protrudes down and through a screw spindle 5 for gate and back movement of the saddle 4 Unduroh.-

engages. The spindle 5 can be in the usual Yfeise on the front by which a handwheel 6 can be set and connected to a moving measuring tape $, which has a front and rear swivel pulley 8 is placed

In a cross member 9, the press beam and the cutting knife are mounted in the usual way.According to the embodiment and according to the invention, the drive of the spindle 5 for moving the saddle 4 is carried out by an electric motor 10 via a gear 11 , the transmission ratio being selected as ρ that the spindle with a. Rapid traverse or a slow gear can be set in rotation.

On the rear end of the spindle 5 sits a gear 12 _f which meshes with two gear wheels 13 and 14, & i «duroh couplings» ζ, B. Sliding clutches 15 and 16 * can be connected to their shafts 17 and 18 »On shafts 17 and 18 there are each a reel 19 and 20, on one of which a magnetic sound carrier in the form of steel wire or a tape is wound, which is wound on the other coil can wobble. The tape 21 runs past a magnetic head 22 of any magnetic sound recording and playback device with amplifier 23, which can be accommodated, for example, in a housing 24 at the rear end of the machine. The individual line connections to the actuating switches, which are advantageously arranged on a control panel located on the front of the cutting table 1, run to the amplifier 23. The magnetic head 22 can be a combined head, through which when the magnetic device is switched to "recording" on the sound carrier 21 Irefrequenzmarkietrungen can be applied and vice versa when the device is switched to "playback" pulses on the device and thus on the control of the drive transmitted and the through the dee during Sucklauf phonogram 21

applied 3 frequency markings can be deleted.

However, a special erase head can also be provided will·

- ⁰ Ie mode of operation of the described arrangements is the following, "Assuming the saddle 4" is in its rearmost position, and it should be carried out in the program that "correspond to certain gate push positions of the saddle 4" so the saddle is switched on by switching on the electric motor 10 by means of the spindle 5 vorwärtsgeschöbsn until you get to. the measuring tape 7 reads the desired first visual intersection, whereupon the motor is stopped and a fine adjustment is made with the handwheel β. The magnetic sound recorder is now switched on and. ; duroh a push button generates a short-term impulse, which in turn applies a frequency marking via the Hagnettonkopf 22 on the sound carrier 21. The saddle is then pushed forward into the next position and a frequency marking is again applied to the sound carrier 21 until the entire cut program has been established. The saddle 4 is now allowed to run back into its position. The magnetic recorder is then switched to "playback"*;

After the stack of paper has been placed on iron 1, it is now switched to advance. As soon as the saddle 4 has now reached the desired first cutting position, a pulse is generated by the frequency marking on the sound carrier 21 in the magnetic device, which is amplified and via contactors; stops the Sattelantriab while the drive for dea pressing "and knife bar · einsehaltet laughing When the edit return the above-mentioned switching operations to, -m example, by controlling the cutter bar after editing or, ä.h by a temporal sub controller,

the spindle 5 is again used to advance the saddle further driven, at the same time the! Donband 21 of the unwinds a reel 19 and winds it on the reel 20 until the next frequency marking on the magnetic head passes, so that now the aforementioned switching operations to shutdown, the saddle 4 and to carry out the Repeat the cut · If the program cut is finished, see above you can let the saddle run back and thereby mark the joyfulness applied to the donut support 21. by Press a delete switch to delete. According to the invention it is possible, in addition to the sound carrier 21, to have a second or more sound carriers 21a a.B. run in parallel and on to apply prequena markings to this ion carrier 21a as well, if you have further modified pro ■ wants to connect grammar cuts. It is also possible to; one and the same tape 21 several independently of one another to bring up running programs that can run one after the other.

The control for performing. Srogrammsehnitten according to the invention allows it that the Magnettongerät can be placed at any point of the machine, and I has the particular Torteil that the program can be applied by simple actuation of a pulse switch on the magnetic recording medium. The new control arrangement has the further advantage that the magnetic sound carrier can be of any length. can be selected and a multiple of the saddle feed path i ^; can amount, so that the sequence markings of the sound carrier ^ cover a much greater distance than the saddle itself during the saddle advance.
