Slitting and cutting device «

When processing a sheet of paper or the like, it often occurs desirable to print on the paper material in sheets or to emboss and then to slit or cut the sheets into the particular, individually desired dimensions. So it is z. B. not unüblioh to produce a printing plate or a silk umbrella in such a way that several Identical cards, drawings or the like. Prints on a single sheet of paper and this sheet of paper after printing in cuts separate pieces so that each piece has an identical or different imprint.

So far, the known machines for cutting consisted of a » Sheet of paper after printing from two parallel, vertically arranged shafts, on which rubber rollers were attached, from which at least some are driven. The bow is inserted between the rubber rollers that it is in contact with

the storage device not every time a sheet of paper or other material runs through the device in order to lower a great ratchet tooth ) 210 ₉ which is fastened to the frame 10, with which in the vertical direction reciprocating slide 120 for the suction device is connected is attached with the help of an arm * When the slide with the suction device runs up and down, then the stop member or the bolt 212 hits the right-angled lever 210, whereby this is pivoted about the point 211 on the frame »This causes the connecting rod 209 moved to the left in FIG. 6, whereby the angle lever 196 swivels around the support 197 in a clockwise direction k * becomes. By this pivoting movement, the draft piece is in turn: noticeable left 198 raised such that the pawl ^198,: when the arm 191 starts to move backward, does not contact the abutment rod 201 into engagement so that check 200 does not move the slide bar to the right (see FIG. 3) For this reason, the pawl arrangement 202 is not pivoted during this particular working cycle, and therefore there is no lowering of the storage device receiving the paper.

As will become apparent below from the description of the operation of the device, the vertical changes Lowering of the carriage 12 ° for the suction device under the influence of the number of sheet strips on the storage device 170 are stacked, or more precisely under the influence of the stack height in relation to the vertical Position of the storage device. When the stack of paper reaches a predetermined point, the weight of the carriage increases 12Ö in that the individual suction devices 126 on the

Stacks of paper rest on, τοη these stacks of paper added, and the carriage is no longer lowered by such a distance that the stop member 212 against the right-angled lever 210 meets. The pawl responds under these conditions, se that the basket or storage device 170 by one more Raetzahn is lowered "

In the following, the operation of the gate direction will be explained with reference to the figures in their entirety and in particular to Figure H. Initially, the operator adjusts the spacing of the knives 99 along the strip cutting rod 93 so that the longitudinal cuts are made at the correct lateral locations of the sheet when this is inserted into the device so that its one edge against the stop 22 on the Infeed table 20 is applied. As stated earlier in the other application, this setting can be carried out by loosening only one locking screw on each knife, moving the knife into the desired position and tightening the locking screw again. The operator then adjusts the lateral position of the suction devices 126 in such a way that, depending on the width of the sheet to be slit, one or more suction cups 127 are provided for each of the sheet strips after the slitting. Selche suction means that are not used have, or switched off simultaneously be put out of operation to prevent them from being damaged thereby because they respectively take up 30 the reciprocating table, suck ₀ As has already been stated above, a Such a shutdown can easily be carried out in such a way that the vacuum hoses 119 are withdrawn from the suction devices or from the line 129 and covered or closed.

Once the knives and suction devices are set correctly are, the device is put into operation that the

Motors 52 and 56 are turned on. By the engine 52 the shaft 41 is set in rotation, which continues during the operation of the device, and the motor 56 eetr * the vacuum pump 57 in rotation so that at the different Elements of the device a negative pressure is generated. Durok the rotation of the shaft 41 becomes the table. 30 on rail 32 and the guide rail 37 »wipe the in solid lines and the position shown in dashed lines in FIG. 3 moved back and forth * The carriage 120 for the suction devices is also continuously moved up and down. The course of time of the two movements is of course chosen so that the individual Suction devices 127 are raised above the table 31 when it reaches its rearmost position, which is shown in FIG 3 is shown in dashed lines.

When the table reaches its rearmost position, which is indicated in FIG. 3 in dashed lines, it stops because of the connection 66 with dead game for a moment so that the suction cups 126 can be lowered against the table without that the paper sheet is smeared or otherwise contaminated. When no sheet of paper has been fed into the machine is, the solenoid 160 on the control system for the suction devices is of course not actuated during this time / and therefore the lever 152 (151) is activated during each operation the machine is pivoted clockwise, as can be seen from Figure 3, to prevent the carriage for the suction devices is lowered completely down to the table 31 which moves back and forth. This control will prevents the table from being sucked by the individual suction cups 127 as a result of which these suction cups would obviously be damaged if the table were to "reverse forward." is returned towards the operator.

The operator places a sheet of paper shown in Figure f generally designated by the reference numeral 220, to the

809824/0250

Feed table 20 and pushes it backwards against the right side of the device shown in Figure 3 and bit laterally • r on the long side at the upright stop 22 is applied. By shifting the arch against the rear At the end of the latter, its rear edge rests against the locking teeth 83 on the stop 80, which is at this point in time are in their lowered position. When the Be ·· The sides are lifted against the upright stop 22 and precisely aligned with the Hessers in this way is, the two vacuum openings 23 through the overlying Bow closed. The openings 23 in the feed table 20 are sufficiently small that they are only closed when the sheet rests on the stop 22 on its entire longitudinal side.

The closing of the openings 23 and thus the exact alignment of the sheet is determined by the vacuum detection gate 26, which the knife solenoid 10? actuated, whereby the arm 100 (see FIG. 10) is rotated counterclockwise around the shaft 102, so that the pin 101 reaches the transverse section 98 of the opening 96 formed in the drive arm 100. At the same time out _h and herlaufende table 30 begins rearwardly against the right end shown in Figure 3 to run, d, h. it begins its transfer movement · At this point in time, the machine carries out three specific operations. First, the cam operated valve 36 is depressed by the cam 49, thereby actuating the suction ports 34 at the rear edge of the table. Second, the stop 80 is rotated counterclockwise as shown in FIG. Finally, the arm 100, which has been brought into its operating position by the solenoid 107, moves upwards, whereby the

909824 / 02E0

Knife 97 rest against the sheet "or press it, which is cut thereby, slit b * w, while the table 30 moves backwards". Each of these “special processes lasts until the transfer table 3 ° reaches its rearmost position, which is shown in FIG. 3 in dashed lines and denoted by the reference numeral 30 ^A ”.

During the period during which the reciprocating Table 30 in Figure 3 is moved "to the right, the The carriage 120 for the suction devices is raised to its uppermost position by the rotation of the shaft 131. If the lisch reaches its rearmost position and pauses for a moment because of the connection 66 with dead play, the suction device lowered, and the suction cups 27 come into contact with the rear edges of the strips of the sheet, that with branches The suction pipe 129 provided is acted upon by pressing down the valve 128 actuated by the cam disk 48 been. At the same time, the underpressure at the table openings 34 is switched off by the a cam operated valve 36 is closed, and consequently the paper strips by the suction cups 127 held back while the table returns to its original starting position.

The carriage 12o with the suction means can 'drop a sufficient distance so that the suction cups come 127 through the intermediary of the solenoid coil 160, which prevents actuation of the ⁿ inoperative reset "facility 15 °, with the sheet on the table 3 ° in contact _e The solenoid 160 is actuated by the microswitch 109 when the arm 100 is pivoted counterclockwise about the shaft 41. In this way, when an exact alignment is determined by the vacuum locking device 26, both the knife actuating solenoid 107 and the suction device shake. ·

Venn the table. 30 in its starting position on the left Returning to Figure 3, the paper strips fall from the rear one Edge of the table on the storage device 170. They are held in alignment with one another by the fact that the above-mentioned Paper guide 180 is suitably set earlier; The rear edges of the strips are placed on the stack in that the carriage 120 for the suction devices At this point, of course, the vacuum on the branched suction pipe 129 is lowered through the valve 128 switched off «

If the paper located on the storage device 170 " stacks are relatively low, the Sled 120 for the suction devices is not hindered by the fact that the weight of the slide over the suction devices 126 is caught by the paper tapes · In this particular one Pail hits the bolt or stop member 212, such as it is shown in Figures 7 and 8, on the right-angled lever 210, whereby the driver pawl 198 is raised and during the backward movement of the arm 191 slides over the stop 201 · If, on the other hand, the height of the paper stack relative to the current position of the storage device exceeds a predetermined limit, so will the weight of the carriage for the suction devices as the carriage descends from the stacked paper and consequently not the entire length of the sole seat 124 is used in the reciprocating suction device or «run through. In this particular case, the The bolt or the stop member 212 does not apply sufficient force on the right-angled lever 210 to move the driver pawl 198 to be raised, and consequently this comes into engagement with the stop plate 201 during the backward movement of the arm 191. As a result of this intervention or this entrainment, as above

It may be that the operator holds the sheet during a particular operation does not align exactly with the stop 22 on the feed table 21 before the transfer table its reciprocating transmission movement begins. "In this particular case, the opening 23 are not covered, and this fact is determined by the vacuum fastening device 26. For this reason, the solenoid 107 is used to operate the solenoid 160 operated for the suction units.

are listed because the knives do not press against the bow « Similarly, the sheet is not fed through the suction device. lines 126 sucked in, since the lowering movement of the carriage 120 is limited by the control "or protection device 150" « This limitation is of course achieved by the fact that the solenoid 160 is not fed, which in the illustrated embodiment also depends on the initial, precise alignment of the arch »In this particular pail lies the front one ^ ante of the arch on the rear edge of the ratchet teeth 83 on when the table 31 begins its return movement, to the left in FIG. 3, and the sheet merely falls onto the depositing device 170, from which it can be removed again by the operator in order to cut it again through the cutting device to run

In Figure 15, a slightly modified embodiment of the invention is shown _{ in which the solenoid for the control «· biw · protection arrangement for the suction devices is actuated by a separate vacuum locking device 221, by which the presence or absence of an arc over the openings 34 in the back and forth running lisch 3 ° can be determined. In this particular case, the vacuum lock device 26 * -, which is connected to the alignment openings 23 in the jest table, only actuates the knife assembly when there is an accurate alignment. An actuation of the suction devices or also a deactivation of the suction devices of the control device 150 depends on whether all the openings 34 in the table 31 are covered by the sheet. The embodiment shown in FIG. B. prevents the suction devices from being lowered and engaging the Tisoh, the suction cups 127 being destroyed in the event that the bow is jammed by the knife or fence after the vacuum lock 26- * has accurately aligned the Bow has been established.
