Definitions

  • the invention is in the field of processing of printed products and relates to an apparatus and a method for pruning in particular multi-leaved folded printed products, such as e.g. Newspapers, magazines and brochures, according to the preambles of claims 1 and 8.
  • Folded printed products are usually trimmed at the edge opposite the folded edge, as well as at the two edges extending at right angles thereto. This is called a frontal cut or a head / foot cut.
  • the device described therein has a plurality of pocket-shaped receiving compartments, which rotate about a common axis of rotation and thereby conveyed along a circular orbit.
  • the receiving compartments are each formed by two adjacent, radially oriented support surfaces.
  • the products are introduced with the folded edge first in the receiving compartments and come to a support, which is located in the area of the compartment floor, to the plant.
  • the support is shaped and positioned to position the products completely and deeply in the compartment, ie, the edge opposite the fold edge is fully contained in the compartment and is significantly spaced from the radially outward open side of the compartment. In this position, the products are laterally aligned, ie in the direction of the axis of rotation or parallel to the compartment floor, and then clamped with a clamping arrangement directly or indirectly against the support surface.
  • a cutting arrangement which comprises at least one stationary counter knife as well as moving knives arranged in the compartments.
  • the counter knife for the head-foot cut is arranged in the direction of movement of the compartments in front of the counter knife for the front section.
  • the mitbewegten knives for the head-foot-section are arranged on axially open sides of the receiving compartments
  • the mitbewegte knife for the front section is arranged on the parallel to the compartment floor open side of the compartments.
  • the stationary counter-blades are located at suitable positions where they can interact with the moving knives scissor-like. Since the components supporting or cutting the front edge must pass the counter-knife for the head-foot cut, the product for the front cut and the head-foot cut must be located at different depths in the compartment. In the known device, therefore, the product must be introduced deep into the bag already during the takeover in order to perform the head foot-cut can.
  • the products are fixed in the compartment by the clamping arrangement.
  • the Klenunan Aunt is released and the product laterally grabbed by a sliding arrangement.
  • the slide assembly pushes the product along the support surface out of the compartment to the position for the frontal cut.
  • the clamp assembly is then reactivated and the product re-clamped in the shifted position.
  • the clamping arrangement is released again and pushed the product through the displacement arrangement so far out of the compartment that it can be taken over by a removal conveyor.
  • the products are conveyed by a gripper conveyor and dropped into the compartments or deeply inserted therein. They slide freely along the support surface until their folded edge is stopped at the support. In this process, it may happen that move the product in the compartment and / or product components against each other.
  • a relatively large distance or time is provided, which corresponds to a movement of the compartments along the circular path over an angular range of for example about 60 °. Nevertheless, it may happen that the products are not completely aligned during the subsequent clamping by the clamping device, which can lead to unclean cutting edges in the trimmed product.
  • the product is brought into the position for the front section only after the head-foot cut and clamped in this position by the clamping arrangement on the front edge.
  • the change between the clamping by the clamping arrangement and by the displacement device may have previously come to shifts or bulging of the not held by the displacement middle product range, so that the front edge is not smooth, but fixed with folds or displacements. This can also lead to unclean cut edges.
  • the EP 0 367 715 describes a method and an apparatus for trimming continuously conveyed printed products with a plurality of transport units circulating on a closed path for receiving the printed products.
  • the printed products are clamped for a first and second cut for trimming a first and second side edge in the transport units.
  • the clamping is released after the trimming of the first side edge, so that an alignment of the printed products can take place before the second cut.
  • the clamp for the trimming of the second side edge is reactivated.
  • the invention has for its object to avoid the disadvantages of the prior art and to provide a device for trimming folded printed products and a corresponding method in which the position of the products to achieve optimum cut quality is well controlled.
  • the device according to the invention likewise comprises receiving compartments which are formed by a support surface and are peripherally open on the support surface on one, preferably three sides, so that the moving knives can be arranged here and interact with stationary counter knives.
  • the device also includes a support which serves as a contact or stop for the folded edge of the products during or after insertion into the compartments.
  • the device comprises a Cutting arrangement for the front section and / or a cutting arrangement for the head-foot-cut, each with the compartments moving along, arranged on the respective open sides of the knife and at least one stationary counter knife.
  • there is a clamping and displacement arrangement for clamping the printed products and for translating along the support surface.
  • the clamping and displacement arrangement preferably acts at least on the side edges of the product.
  • the support is adjusted so that the products are introduced into the compartments during the transfer, that the edge of the folded edge opposite the printed products after insertion into the compartments is in the immediate vicinity of the open side of the compartments.
  • the product is not introduced deep into the compartment as in the prior art, but the front edge is located at a small distance from the moving knife for the front section.
  • the front edge is beyond these mitbewegten knives or is gently pushed by sliding along the support in this position.
  • the product preferably after alignment in lateral (ie parallel to the compartment floor extending) direction, fixed by the clamping and displacement arrangement at the perpendicular to the fold edge extending side edges. This is done before making the first cut.
  • the lateral fixation is only released again when the printed product is dispensed, with the product being brought, if necessary, with the clamping and displacing arrangement into the operative positions provided for cutting and for dispensing the product.
  • the product is introduced into the compartments at a lower depth than in the prior art.
  • the distance over which the products fall freely compared to the prior art significantly shortened. Uncontrolled movements are thus avoided.
  • the products can be aligned with greater precision because of the need for rough alignment.
  • the length of the portion of the trajectory in which the alignment takes place can be shortened.
  • the front section can be made immediately after alignment, without the product must be moved again within the compartment. Overall, this results in a better quality of the cutting edge.
  • the product usually has to be drawn into the compartment for the head foot cut, this is done very controlled due to the preferably not released clamping on the side edges. For this reason, it also has no effect on the quality of the cut edges when a possibly existing to fix the front edge existing clamping member after the front section is released.
  • the stationary counter-blade can optionally be switched off, if the corresponding section is not to be executed.
  • the stationary counter knives are preferably arranged so that first the front cut and then the head-foot cut is made.
  • the support is preferably displaceable in such a way that the product projection via the front-cut knife or the corresponding open side of the compartment always has essentially the same width.
  • the support is preferably formed by one or more stationary elements which are located in the region of the device in which the products are introduced into the compartments and subsequently aligned.
  • the support can also be realized by a mitbewegten and preferably movable compartment floor.
  • the control arrangement for controlling the clamping and displacement arrangement may be in the form of a stationary control link and cooperating controls.
  • the clamping and displacement arrangement preferably comprises at least one clamping member with at least two clamping elements, which are able to receive a printed product between them and with a control arrangement, for example in the form of a stationary control link and cooperating controls, between an open position and a clamping position relative to each other movable are.
  • a control arrangement for example in the form of a stationary control link and cooperating controls, between an open position and a clamping position relative to each other movable are.
  • one of the clamping elements may be formed by the support surface of the compartment and the other by a lever pivotable relative thereto.
  • the mutually cooperating clamping elements are independent of the support surface and, as a displacement device can be moved relative to the compartment floor or away from it to bring the product from the position for the front section in the position for the head-foot-cut.
  • the support surface can serve as a guide for the corresponding clamping member.
  • a first clamping member for clamping the front edge and at least two further clamping members for clamping the perpendicular thereto extending side edges are present.
  • the first clamping member cooperates with the support surface, e.g. with a transom integrated or attached thereto. It may, but does not have to be postponed.
  • the further clamping elements preferably cooperate with counter elements which are movable relative to the support surface.
  • the clamping members for the front and side fixation are preferably independently controllable, so that the front clamp can be solved after performing the frontal cut and the product can be brought into the position for the head-foot cut, without the side clamp must be solved.
  • the receiving compartments are preferably driven in rotation about a common, preferably horizontal axis of rotation, extend in the radial direction away from the axis of rotation and are open on the radially outer side and on both sides extending perpendicular thereto.
  • Fig. 1 shows the inventive device 1 in a view from the side.
  • the structure and operation correspond in principle to the device of the EP-A 0 753 386 .
  • Differences exist mainly in the order of the cuts and in the construction of the clamping and displacement assembly 20, which in the Fig. 2 . 3a + b is explained in more detail. These differences will be discussed below EP-A 0 753 386 directed.

  • a spring 214 pushes the carrier element 240 away from the lever 202 in its radially inner region 240 '.
  • a pressing action is generated when closing the clamping member 22, which acts first on the near the compartment floor product areas, ie from the folded edge 102 toward the front edge 104, so that any air trapped in the product is struck.
  • the pressing plate 204 has an outer edge 204a extending parallel to the side edge of the support surface 14 and widens in its radially outer end region 204b to the interior of the support surface 14 out.
  • the clamping member 22 is operatively connected to a carriage 208 which is displaceable in a slot 19 of the support member 12 in the radial direction.
  • the carriage 208 has a control element 210 in the form of a control roller. This cooperates with the setting of the radial position with a first stationary control link 62, which is part of the control arrangement 60.
  • the lever 202 is movable relative to the support member 12 between an open position and a clamping position, in particular pivotable. For this purpose, it is pivotally mounted about an axis 216 on the carriage 208. He has at its radially inner end another control 212, also in the form of a tax role. This acts to adjust the pivoting position of the lever 202 with a second stationary control link 64 (FIG. Fig. 4 ) together.
  • the clamping device 26 for the front clamping comprises a further lever 218 which is pivotable about a further axis 220 and mounted on an intermediate between the two mentioned above, serving as a support for the supporting elements 12, 13 wheels 3, 4 middle wheel disc 5.
  • the middle wheel disc 5 retains its central position during a format adaptation, ie axial change in distance of the outer wheels 3, 4, and is not adjusted.
  • the clamping device 26 for the front clamping further comprises a T-shaped in the top pressure plate 228 which is pivotally connected via an elongated coupling piece 230 with the other lever 218.
  • the radially outer edge 228a of the pressure plate 228 is parallel to the axis of rotation 16, the front cutting blade 32 and in the application to be trimmed front edge of the product.
  • the width of the front-cut press plate corresponds at least to the maximum product width. So that the front-cutting press plate on the counter knife for the side cut passes In the case of use, the product must be withdrawn to the compartment floor.
  • the coupling piece 230 is on the one hand pivotally connected to the lever 218 and on the other hand connected at its radially outer end via a telescopic rod 226 with the support member 12, 13 of an adjacent compartment 10 ( Fig. 3a + B). Between the lever 218 and the adjacent compartment 10, a compression spring 232 is arranged, which presses the lever 218 to the support surface 14. The pivoting position of the further lever 218 can against the spring action with a third control link 66 (FIG. Fig. 4 ) are set, which cooperates with a radially inner end of the further lever 218 arranged control (control roller).
  • the front-cutting press plate 228 pushes the side-cut press plates 204 against the support members 12, 13 and the crossbar 15, respectively.
  • a counter-clamping element 224 which cooperates for the purpose of lateral clamping with the pressure plate 204, is coupled to the carriage 208 and is displaced in the radial direction during movement of the carriage 208. Its top serves as part of the support surface 14.
  • the support 50 consists of one or more planar, preferably circular segment-like, stationary elements which extend in a plane perpendicular to the axis of rotation 16 and engage between the support elements 12, 13. They are preferably displaceable for format adaptation in this plane. Its upper edge 52 has a constant or along the trajectory decreasing distance from the blades 32. In the latter case, the product is only fully disposed in the compartment and is supported by the support 50 during the alignment back in a position in which the front edge of the knife 32 surmounted raised. These are movements that are preferably small compared to the displacement required for the sidecut.
  • the product is pressed against the support surface 14 by the pressure plates 204, 228 at its side edges and at the front, in particular against the counter-clamping elements 224 (side edges) and the transverse bar 15 (front edge).
  • the outer edges of the press plates 204, 228 are parallel to and preferably as close as possible to the product edges to be cut. Due to the pivotability of the pressure plate 204 relative to the lever 202 and the first spring 214, which presses the pressure plate 204 away from the lever 202, a good, over a large area uniformly acting clamping is made regardless of the product thickness and air to the front edge 104 out struck. Likewise, a good surface clamping effect is achieved by the pivotability of the front pressing plate 228 relative to the lever 218. A local shifting of product parts and thus the formation of wrinkles or bulges of the clamped product is prevented.
  • the front clamp member 26 carries the side clamps 22, 24 from the open position to the closed position, the front clamp can be opened independently of the side clamp to place the products 100 in the side cut position after the front cut, i. to move to the axis of rotation 16 out.
  • the levers serve as drag levers.
  • the control scenes must apply only the counterforce necessary for closing or opening.
  • the side clamping members 22, 24 are, as mentioned above, mounted on separate wheel discs and controllable independently of each other, but are moved in synchronism with each other parallel to the support surface 14 during operation.
  • the front clamping member 26 is independently mounted on the central wheel disc and is moved neither in the radial direction nor for format adaptation.
  • the products 100 are introduced in a transfer region with their folded edge 102 ahead of the grippers 72 of the feed conveyor 70 into the compartments 10 and between the support surface 14 and the open clamping elements 22, 24, 26.
  • the press plates 204, 218 are initially in a mutually aligned position (middle still held by the gripper 72 product 100 in Fig. 4 ). Subsequently, first the side clamping member 22, 24 and then the front clamping member 26 is approximated to the support surface 14. At the same time, the gripper 72 is opened and the product 100 is released.
  • the stationary support 50 In the transfer area is the stationary support 50, at the top 52, the folded edge 102 comes to rest.
  • the support 50 is shaped and positioned so that its upper edge 52 has a predetermined distance D from the blades of the radially outwardly facing front cutting blade elements 32. This distance is set so that it is smaller than the product length in the insertion direction (radial direction).
  • D the predetermined amount D 'on the blade of the blade 32 via. It is thus already in the position in which the front section can be performed.
  • the clamping members 22, 24, 26 After insertion, the clamping members 22, 24, 26 so far approximated by appropriate shaping of the responsible for the opening / closing Steuerkulissen 64, 66, that the product seen in the circumferential direction is positioned substantially parallel to the support surface 14, but moved parallel to it can be.
  • the product 100 In the area A of the orbit, which extends over an angular range of approximately 60 °, the product 100 is aligned by alignment elements, not shown here, for example laterally arranged alignment bands, in the direction of the axis of rotation 16. At the end of the region A, it is clamped against the support surface 14 or in the lateral region against the displaceable counter-clamping element 224 by completely closing the clamping members 22, 24, 26.
  • Fig. 5 top and second highest compartment 10).
  • This region B extends over an angular range of approximately 30 ° ( Fig. 5 ).
  • the stationary counter-blades 44 for the head-foot cut are arranged so that the two side edges are trimmed simultaneously and with the same cutting direction ( Fig. 6 ).
  • the radially outer end of the counter knife 44 is within the path of the moving blades 32 for the front section. Therefore, it is necessary to move the products 100 inward before the head-foot cut (area C).
  • the product with the clamping and displacement assembly 20 by moving the carriage 208 is again moved outwardly to a position in which the front edge 104 protrudes beyond the front cutting blade 32, for example 30 mm, and can be taken by the grippers 82. ( Fig. 7 ).
  • the corresponding region E extends over an angular range of approximately 40 °.
  • the clamping members 22, 24 are opened for the side clamping when the products 100 have already been gripped by the gripper 82. The transfer is therefore very controlled.
  • the invention has the advantage that the product 100 does not have to be completely introduced into the compartments during the transfer by the feed conveyor 70. Thus, immediately after transfer, the product 100 is in the correct radial position for the frontal cut, which is performed immediately following the registration process. There is therefore more time to align in area A so that it can be more precise. Furthermore, the product 100 is securely fixed after alignment until transfer to the removal conveyor 80 by the lateral clamping elements 22, 26, which are also displaceable in the radial direction.
  • the front edge 104 of the product 100 is preferably initially pressed against the support member 12 by the front presser plate 228 and released after the frontal cut is made to allow the product to be displaced inwardly. It does not have to be re-clamped again.
  • the device 1 shown in the figures represents only a preferred implementation of the invention.
  • the product can be introduced into the compartments 10 in another way instead of the folded edge 102 ahead.
  • the three edges of the product are trimmed, which are not the leading edge during insertion.
  • the stationary knives 44 for the head foot cut or the front cut can also be brought into an inactive position.
  • a stationary one Support can also be a mitbewegte support available, for example, an adjustable compartment floor.
  • the front clamping by the front clamping member 26 is basically not mandatory, but leads to an improved cut edge quality.
  • the front clamp press plate 228 need not necessarily overlap the side clamp press plates 204; the press plates can also be arranged side by side.
  • an overlap has advantages in the realization of a pressing surface lying in a common plane. It is also possible that the front clamping member 26 with the side clamping members 22, 24 is displaceable.
