Definitions
- the invention relates to a folding apparatus for the production of folding products provided with a cross-fold parallel smooth cut with at least one cylinder provided with folding jaws, which is attached to a cylinder provided with at least one folding knife and in the area between its folding jaws is each equipped with a scissors-type knife which is equipped with a counter knife cooperates, and with controlled lifting tongues engaging in the folding flaps that release the cross-folded products.
- the excavation tongues are arranged stationary in the direction of rotation outside the respectively assigned flap cylinder. Since the scissor-cut knives protrude slightly beyond the circumference of the assigned flap cylinder, the lifting recesses which engage in the flap-cylinder must, if they are arranged on this scissor-cut knife, which is the case with folders with only one flap cylinder, with each end of a scissor-cut knife with its end engaging in the fold-flaps be lifted over the scissors-cutting knife to prevent collisions between the excavation bars and the scissors-cutting knives passing by.
- At least one stationary guide table is provided in the area in addition to the circumference of the cylinder receiving the jaws cooperating with the lift flaps, and that the lift tabs are received on the cylinder carrying the assigned jaws and can be activated when passing each guide table.
- the lifting tongues advantageously have the same speed as the folding products to be lifted out of the assigned folding jaw, so that during the lifting process there are no significant relative movements between the lifting tongues and the folding products, which is very gentle affects the products and the printed image.
- the excavated products are transferred to a standing guide table, which ensures reliable guidance and at the same time allows sufficient space for unhindered passage of the scissor-cutting knives.
- These can therefore be arranged on the last jaw cylinder in the working direction, which is inevitably the case where only one jaw cylinder is provided.
- the measures according to the invention can therefore be used with particular advantage in the case of folding apparatuses for producing once folded products and provided with a smooth cut that is parallel to the transverse fold.
- the stationary arrangement of the associated control table ensures a constant distance between the table support and the belts beyond which the other belts are held.
- the belts of the upper, over walking away from the control table The set of tapes lies snugly on the assigned jaw cylinder, which ensures that the products are securely drawn into the tape guide.
- the stationary control tables also require relatively little space, so that the accessibility of the associated jaw cylinder is practically not affected.
- the guide table or the guide tables with their contact surface can be oriented approximately tangentially to the circumference of the assigned folding jaw cylinder, which practically results in a deflection-free drawing of the products into the belt guide.
- a further advantageous measure can consist in the fact that the guide table or the guide tables is or are tapered like a wedge cylinder. This ensures that the contact surface of the guide tables can reach up to the area of the cylinder surface and nevertheless sufficient stability is ensured.
- control table or the control tables can consist of guide tongues arranged next to one another at a distance. These can come into rake-like engagement with the lifting tongues that are received on the folding jaw cylinder and move past them, which ensures trouble-free insertion of the products into the belt guide.
- a lifter bar equipped with a plurality of lifting tongues distributed over the cylinder width can be provided in the area of each folding jaw, which is expediently arranged in the direction of rotation in front of the assigned folding jaw. With their rear ends in the direction of rotation, the lifting tongues engaging under the folding product held in the respectively assigned folding flap are advantageously dragged past the assigned control table, which can have an advantageous effect on operational safety.
- a further expedient development of the superordinate measures can consist in the fact that the lifting bar is pivotably mounted in the lateral cylinder flanges and is connected outside of it with a pivoting lever which is provided with a feeler element which scans a control curve arranged fixed to the frame.
- control curve can be adjusted about the axis of the assigned jaw cylinder. This measure advantageously enables the activation of the excavations at different points, so that alternatively operable displays can be provided.
- a guide table is expediently provided in the area of each delivery.
- the folding apparatus shown in FIG. 1 consists of a folding jaw cylinder 1, which is provided with two folding jaws 2 and against which a folding knife cylinder 4 provided with a folding blade 3 is employed, which in turn cooperates with a cutting cylinder 5 to form a cross cutting device.
- the cutting cylinder 5 is provided with a cutter bar 6 which interacts with a cutting groove 7 provided on the folding cutter cylinder 4.
- the paper web 8 entering the cross cutter, which is to be guided over a folding former 9 to produce a first longitudinal fold, is divided into arcuate products, the front end of which is received by punctures 10 arranged on the folding knife cylinder 4 and acting in the direction of rotation behind the cutting groove 7.
- the arcuate products are transferred from the folding knife 3 to the opposite folding jaw 2 of the folding jaw cylinder 1, forming a transverse fold.
- the once cross-folded products are removed from the folding jaw cylinder 1 and either placed as so-called tabloid products in a paddle wheel 11 arranged below the folding jaw cylinder 1 or fed via a belt guide 12 to a sword folding mechanism 13 for producing a second longitudinal fold.
- the cross section caused by the interaction of knife bar 6 and cutting groove 7 usually has the shape of a so-called sawtooth cut.
- the punctures 10 cause permanent punctures in the area of the leading edges of the sheet. It is therefore often desirable to remove the rear product ends after the transverse fold has taken place by means of a clean, smooth cut.
- the jaw cylinder 1 is equipped in the area between its jaw cylinder 2 with scissors-type cutters 14 which cooperate with a counter knife 16 arranged on a cutting cylinder 15 arranged on the jaw cylinder 1 and arranged downstream of the jaw cylinder 4 in the direction of rotation of the jaw cylinder.
- the rear ends of the folding edge 2 are held in the folding flap 2 which precedes in the direction of rotation in each case by the scissor-cut knife 14 and the associated counter knife 16 folded products in the form of a smooth cut.
- the separated strips are picked up, for example, by needles arranged downstream of the counter knife 16 on the cutting cylinder 15 and then sucked off by the latter.
- the cutting cylinder 15 is immersed in a suction channel 17 which can be subjected to a vacuum.
- a guide table 18 is provided which is fixed to the frame walls and whose table support 19 is oriented approximately tangentially to the circumference of the folding jaw cylinder 1.
- the jaws 2 of the jaw cylinder 1 are opened automatically.
- lifting tongues 20 are provided on the folding jaw cylinder 1 in the area of each folding jaw 2, which with their ends engage under the folding products which protrude into the respectively assigned folding jaw 2 and when they pass the relevant guide table 18 from the assigned folding jaw 2 lift and hand over to the control table 18.
- the guide tables 18 can expediently be formed by a plurality of tongues arranged next to one another at a distance, which are laterally offset in the axial direction with respect to the guide tongues 20, so that the activated lifting tongues 20, which in the activated state assume approximately the position indicated by broken lines in FIG. 1, can hereby engage in arithmetic, which enables the products to be reliably transferred to the respective control table 18.
- the cylinder-side end of the guide tables 18 is so far apart from the periphery of the adjacent jaw cylinder 1 that the scissor-cut blades 14 projecting slightly over the periphery can pass unhindered.
- the guide tables 18 are tapered wedge-like on the cylinder side, so that the required distance from the jaw cylinder 1 is minimized.
- the band guide 12 leading to the sword folding mechanism 13 consists of an upper band set 21 and a lower band set 22.
- the bands of the upper band set 21 lie snugly on the flap cylinder 1 and run with a small distance corresponding to the product thickness, which is the distance between the facing bands corresponds to the upper and lower belt guides 21 and 22, respectively, over the bearing surface 19 of the guide table 18 arranged at the entrance to the belt guide 12.
- the lower belt guide 22 which is correspondingly shortened compared to the upper belt guide 21, is provided in an extension of the support surface 19 of the guide table 18 provided at the entrance to the belt guide 12, the lower belt guide 22, which is correspondingly shortened compared to the upper belt guide 21, is provided.
- the bands of the band guide 12 run at a speed corresponding to the peripheral speed of the jaw cylinder 1.
- the ends of the lifting tongues 20 which come into engagement with the respective product to be lifted thus have, in the activated state, indicated by broken lines in FIG. 1, practically the same speed as the bands of the band guide 12, so that when the latter is taken over from the associated folding flap 2 excavated product by the band guide 12 results in no relative movement between the product drawn into the band guide 12 and the lifting tongues 20.
- the same also applies to the lifting process itself, since the lifting tongues 20 are arranged to be fixed in the direction of rotation relative to the product engaging in the respectively assigned folding jaw 2 due to their arrangement on the folding jaw cylinder 1.
- a pressure roller 23 is provided above the guide table 18 assigned to the paddle wheel 11, which prevents the ends of the products running onto the guide table 18 assigned to the paddle wheel 11 from tipping over and ensures reliable transport of these products already released by the respectively assigned folding flap 2.
- a pivotably mounted lifter bar 24 is provided in the area of each folding jaw, on which the individual lifting tongues 20 can be detachably fixed, for example by screws.
- the jaws 2, d. H. whose fixed stop bar and pivoting swivel bar are provided over their length with several, provided in the axial region of the lifting tongues 20 interruptions, in which the lifting tongues 20 can engage in their rest position, indicated by solid lines in FIG. 1, in which they the front edge of the in grasp the product that engages the respectively assigned flap 2.
- the lifting tongues 20 can simply be formed by wire or sheet metal brackets, which can expediently be bent in accordance with the curvature of the folding jaw cylinder 1 receiving them.
- the lifter bar 24 is arranged in the direction of rotation in front of the respectively assigned folding flap 2.
- the lifting tongues 20 thus engage with their rear end in the direction of rotation in the respectively associated interruption of the associated folding flap 2.
- the ends of the excavation tongues 20 which reach under the product to be lifted are dragged past the control table 18 to which a product transfer is to take place and can therefore be rejected in an advantageous manner without interference.
- the lifter bar 24 is, as can best be seen from FIG. 2, pivotably mounted in lateral edge flanges 26 placed on the axis 25 of the jaw cylinder 1. At one end, the lifter bar 24 is extended beyond the associated swivel bearing and is provided with a swivel lever 27 fastened to it, on which a feeler roller 28 is rotatably supported, which is guided along a control curve 29, the contour of which results in the activation of the lifting tongues 20 at the desired location.
- the control cam 29 is integrally formed on a ring 30 which is rigidly attached to the adjacent frame side wall 31 with respect to the rotatably mounted folding jaw cylinder 1.
- the control curve 29 assigned to the lifting tongues 20 is designed here as an inner curve.
- the folding jaws 2 are likewise controlled in a similar manner by means of a control curve, which can expediently be designed as an outer curve.
- the control curve assigned to the folding jaws 2 can also be integrally formed on the ring 30 as the outer curve 32 opposite the control curve 29, which results in a particularly compact design.
- the folding jaws 2 and the lifting recesses 20 assigned to them must be activated at correspondingly different circumferential positions.
- the ring 30 receiving the control cams 29 and 32 is simply arranged to be rotatable about the axis 25 of the jaw cylinder 1.
- the ring 30 is provided with arcuate guide slots indicated at 33 in FIG. 1, into which guide pins fixed in the frame engage.
- shoes 34 engaging in the guide slots 33 are provided, which are provided with a thread for receiving retaining screws 35 which pass through the frame side wall 31 and have their heads supported thereon.
- the ring 30 can be brought into the desired rotational position.
- the ring 30 is provided with a blind bore 36 into which an adjusting rod can be inserted, which enables the ring 30 to be easily rotated.
- corresponding markings 37 can be provided in the region of the facing side of the frame side wall 31, which are easy to align with a pointer 38 molded onto the ring 30.
