(54) CYLINDER WITH FALSE VALVES FOR ROTARY FETZER
I
The invention relates to cylinders with folding valves of the rotary faltzer. 4 Liezers of this type of PS 1e1c are in rotary printing machines. Cylinders with folding valves are designed in cooperation with a cylinder having a folding knife, in most cases to provide with a transverse fold, already longitudinally falsetto and products separated from the web. Moreover, the invention can also be used to control, for example, the movement of a folding knife in a cylinder with a folding knife.
A cylinder with folding valves of this type is known in which the folding cam is located on the cylinder axis through the valve levers, etc., which control the folding valves. For adjusting the opening of the folding valves depending on the different thickness of the product between. lever valves and a folding valve located axially n &
a movable coupling having a toothed sector with oblique teeth, which engages with a corresponding serrated line connected to the folding valve, and also having oblique teeth.
Although this way you can change the gap of the folding valve, however, when servicing different transmission frequencies (for example, for selective gripping and the first transverse fold or for transmitting to the subsequent positions of the transverse and longitudinal fold), it is necessary to change the cam disc according to the task. In addition, the relative difficulty of adjusting the folding valve flaps is relatively high .; after each change of the cam disc, time is required for adjustment. In this connection, the location of the variable segments of the distribution cam is unsuitable.

A cylinder with folding valves is also known, in which, at each folding valve, two selectively actuated bigoval eccentrics, which are selectively actuated, interact with two selectively actuated sleeves of the distribution roller. If the production is directed to the first processing site, the folding valve binder is connected to one distribution roller sleeve, if to the second processing location, the first distribution roller sleeve is disconnected simultaneously with the second sleeve and, thus, the second bigial eccentric will be engaged. The cams, designated as bigovalny eccentrics, are also stationary, as a result of which: servicing more than two subsequent processing places requires changing them, adjusting, etc. On the other hand, it is impossible to adjust the diameter of the folding valve opening depending on the thickness of the product. The purpose of the invention is to reduce the time required for conversion when you see an order, as well as to improve the cylinder with the folding valves so that several different phases of movement and alternation are made. folding valves were adjusted without thorough dismantling, installation and adjustment of the respective distributor cams. In addition, the fine adjustment must be carried out by different phases of movement depending on the thickness of the foldable product. This goal is achieved by the fact that the distributor for opening the folding valves to a different diameter of a BiviecTe ring. grooves as a block are located axially on the vtusse controlled by a key, forceful inputs put into action, fixed in the cooj working position, the end teeth are coupled with the gouge, the sleeve at one end has the engagement of the worm wheels, with which the inserted teeth engage. for the radial adjustment of the screw, for; the locking cam is designed as a Kopnjca connection bearing a sleeve, fixedly attached to the wall of the faltser, and contact rollers interacting with the distribution cams, raising May with during the conversion. In addition, eccentric cams, which are controlled by a worm wheel, are provided to lift the contact rollers, which are regulated by the 1st through spindle on the front wall of the cylinder with folding folders. At least the frontal tooth is provided with stop grooves receiving the stopper. In the proposed device, due to the axial location of the shifting distribution cams, ajioe number of contact rollers is necessary; the conversion time can be greatly reduced, since there is no need for a substantial change of cams with appropriate adjustment work; In addition, for all the work done in the calculation for the task, the cam's smooth running is maintained. FIG. 1 shows a folding apparatus, with various transfer points for transfer from the folding cylinder of the side of the zid cylinder; in fig. 2. - partial longitudinal section through shshindru with folding and valves and its location in FIG. 3 shows section A-A in FIG. 2. In most cases, the role of a rotary printing press coming from a rotary press is already longitudinally folded 1. supplied through a pair of guide rolls 2 with exact observance of the wiring to the cylinder with a folding knife 3, which also carries the backslash knives 4. to the cutting knife 1-6 knives after the holder 5. Folding knives 6 are inserted cut off from the blade 1 held by graphics 7 7 products 8 into folding valves 9 cylinders folding valves 10 which can also be performed as a cylinder with folding valves and a knife. From there, the product 8 is supplied either at position A through ribbons (not shown) or a longitudinal slider unit P, or at position B is immediately laid out through a perforator 12, or at position C through the following folding blades 13 is introduced into the folding valves 14 of the cylinder with folding valves 15, .to from there through the drum of the collector 16 to arrive at the acceptance. It follows that, although the folding valves 9 are always closed at the point of contact with the corresponding folding knife 6, however, according to the task, they must be open in three different positions A, B or C. FIG. 2 shows distribution cams 17 for realizing w. Pere:.;.: Chi in position A, 18 for transferring products 8 to position B and 19 d, n to position C. Dispenser Shzu kzlachk 1719 by means of a large cat-scale. Screws 20 Scratch1E1Pz1 in. Place with - holders :. with a groove 21 in one block, krtoryg. g, means the keys 22 on the sleeve 23, covering fixed on the wall of the fall. The center 24 can mix from the parallel axis and rotate with the sleeve 23. The sleeve 23 at one end has a gear 25 cherv of the first wheels, with which the screw crawls to 26 manually actuated or, for example, an electric motor 28 through a pair conical wheels 27. By moving the che - (ka) (26), respectively, of the sleeve 23, together with the distribution cams 17-19, it is possible to select and adjust, depending on the paper thickness, the opening time of the 4 fold flaps 9. Adjusting the opening point is beneficial and necessary Also for other technical reasons. A large number of end teeth interlock with the ring and the groove (21). Thus, the position of the distributing cam (1 7-1 9) located on each folding valve (29) of the contact roller 21 is opened as necessary to open the folder by rotating the adjusting screw 32 along the internal thread 33 of the axis 34, the end teeth of the DZ move. At least one of the circumferentially distributed end teeth 30 is stopped by means of a stopper 35, which engages with the stop grooves 36 of the end face 30. The locking grooves 36 with their location and horizontal spacing correspond to the location of the distribution cams 17 to 19. The contact rollers 31 are located on the same axis 37 and are located on the levers of the folding valves 38, which are touch-sensitive rollers (39) that interact with the so-called closing cam 4. This closing cam 40 is designed primarily as a connection of the housing 24 enclosing the voucher 23. The closing cam 4O can be positioned rigidly, since the closing of the folding valves 29 occurs regardless of The ligans of the product being processed 8 and various open positions (A, B or C) of the folding valves 29. In order to distribute the cams 1719, when changing the task, could axially move regardless of the location of the contact rollers 31 relative to the distribution cams 4 1719, it is necessary in each case to raise 56 stroke roller 31, For this purpose, a controlled manual spindle 41 is located in the cylinder with the folding valves 10, on which the worm is fixed to 42, which interacts with the serial gear ECU 43. Eccentric Cams 44 are located on the worm wheel 43 in such a way that, when turning, the OCI raise the auxiliary rollers 45 and thereby turn the fold valve levers around its axis 46, as a result of which the contact rollers 31 are raised as well. This turns against the pressure of the spring 47, which is located between the stopper 48 and 49 of the lever of the folding valve 38 fixed on the front stack of the cylinder with the folding valves U. To prevent the axial locking remeschenie switching cams 1719 at nepripodn ies contact roller 31, the stopper 35 is electrically fixed in a known manner to such a time until the eccentric cams 44 reach their lifting positions and thus result in corresponding effects, conductive switch. Claim 1. Cylinder with folding valves for rotary folding, the movement of the 1st section of the valve is controlled by cams and rollers and folding valves with several cam for locally different product output, characterized in that, in order to shorten the time re-equipment when changing the order, reversing cams for different opening of folding pacncv flaps are put together with a ring with a groove block moving axially on the hub driven by the ventricular with a key, with a ring with a groove, manually controlled end teeth, which are locked in their: appropriate working position, hub, engage at one end; Worm wheels, with which a worm driven for radial movement, engages, a cam that closes the fold the valves are designed as a shoulder of the body carrying the sleeve, closely connected with the fal 7 & and the false wall of the falierv, and the rollers are applied when refitting.
