German Patent Application No. 4215779A

  It is an object of the present invention to provide an auxiliary pile support including a number of support parts that is flexible on one side and can be moved in a self-supporting manner from a preparation position to a working position in an extended position on the other side. It is to equip the machine mentioned at the beginning.

  To achieve this purpose, the support part mentioned at the beginning has extensions extending beyond its rotary joint, each extension facing away from the insertion direction following in the insertion direction. It is comprised so that it may hit from the bottom the extension part which has faced the insertion direction of the front support component before doing.

  The auxiliary pile support configured in this way becomes an auxiliary pile support base at the working position or an arrangement of individual bar-like support members, depending on the geometric shape of the support component.

  This type of auxiliary pile support, as a rule, is a non-stop operation of the paper discharge device regardless of whether an auxiliary pile support base is formed at the working position or whether individual bar-like support members are formed. (Non-Stop-Betleeb). However, when used for the non-stop operation of the sheet feeding device, it is preferable to intend a configuration in which a rod-shaped support member is formed. It is intended that the support member can be inserted into a groove normally provided in the paper stack.

  However, in any case, in order to move the auxiliary pile support according to the present invention to the working position, the auxiliary pile support moves along with the auxiliary pile support from the preparation position to the working position in the insertion direction on the path of the auxiliary pile support. There is no need for a support device to keep it in an extended position.

  In addition, the flexibility of the auxiliary pile support when used for non-stop operation of the paper feeder is that there is a structural space under the conventional paper stand to store the auxiliary pile support in the ready position. There is a special advantage in that it is sufficient.

  Next, embodiments of the present invention will be described with reference to the drawings.

  The rotary printing press for processing sheets schematically shown in FIG. 1 comprises a machine area 1 with two processing sections in the form of printing units 1.1 and 1.2, by way of example, whereby two colors Can be printed. Separate printing units can be provided for other colors. For subsequent process steps, such as varnishing, intermediate drying, perforation, etc., separate processing sections can be provided. In the case illustrated as an example, the printing units 1.1 and 1.2 operate in a wet-offset manner, so that the inking device 1.3 and the dampening device 1.4 respectively and the plate cylinder associated therewith. 1.5, a blanket cylinder 1.6 that rolls in contact with the plate cylinder 1.5 during operation, and an impression cylinder 1.7 that guides each sheet of paper.

  In order to supply the sheets to the printing units 1.1 and 1.2, the uppermost sheet 2.2 is taken from the pile 2.3 by the sheet separating device 2.1 and conveyed and aligned. A sheet feeding device 2 is provided to the device 2.4, and the transport aligning device 2.4 is a sheet that precedes each other in the processing direction among the sheets that are separated and overlapped. The paper is aligned with the front end stopper and at least one side surface stopper, in particular after the conveyance in the direction towards the front end stopper, which is performed by the suction belt base.

  Here, a swinging conveying gripper 1.8 attached to the first processing unit, which is the printing unit 1.1, picks up the aligned sheets 2.2 and feeds them into a sheet feeding drum 1.9. , And the sheet feeding drum 1.9 further passes it to the impression cylinder 1.7 of the printing unit 1.1. After passing through the pressing gap of this printing unit 1.1, the impression cylinder 1.7 is fed between the respective impression cylinders 1.7 of both printing units 1.1 and 1.2. 1. A sheet 2.2 is transferred to a transfer device in the form of 10.10. When the machine is configured for double-sided printing, a reversing device capable of switching between the front surface printing operation and the double-sided printing operation is provided instead. The impression cylinder 1.7 of the printing unit 1.2 takes the sheet 2.2 from the sheet guide drum 1.10 and passes it through another pressing gap, and finally each sheet 2 2 is transferred to the endless conveyor 3.5 that circulates during operation of the paper discharge device 3 that forms the printed material pile 3.2.

  At the time of actual printing, in the pile 2.3 of the paper feeding device 2, the production level, that is, the height position of the uppermost sheet 2.2 in each case, and the sheet that has been released in the paper ejection device 3. The falling height of the paper 2.2 is maintained by following the paper stacks 2.5 and 3.3 supporting the pile 2.3 and printed pile 3.2, respectively, with each lifting device. Only the lifting chains 2.6 and 3.4 supporting the paper platforms 2.5 and 3.3 are shown.

  As already mentioned, an auxiliary pile support of the type described in detail below can be used both for the non-stop operation of the paper feed device and for the non-stop operation of the paper discharge device. However, in the following, as an example, the provision of such equipment in the sheet feeding device will be described.

  Accordingly, FIG. 2 shows a portion of the sheet feeding device shown in FIG. As will be described below, the auxiliary pile support 20 is flexible on one side, is strictly articulated, and can be changed to an extended posture on the other side. The flexibility is used to store in a space-saving manner (here, below the transport / alignment device 2.4) at the preparation position. The auxiliary pile support 20 is supported by the crosspiece 2.7 (see FIG. 1) whose end facing the insertion direction can be moved up and down in the insertion direction indicated by the direction arrow 21 from this preparation position. The position can be adjusted to the position. After use, i.e., after the almost exhausted pile 2.3 has been merged with the new main pile in a known manner, the auxiliary pile support 20 is repositioned back to the ready position.

  The auxiliary pile support 20 includes support parts that are pivoted directly to each other via an axially parallel rotary joint that is continuous in the insertion direction, in particular from the end facing the insertion direction. As will be described in detail later, the position where the self-supported length of the area in the extended posture is the position adjustment direction by the length of one support component, starting from the end facing the insertion direction It is possible to shift to the extended posture continuously so as to always extend.

  When the auxiliary pile support 20 is sandwiched in the horizontal direction at the end facing the insertion direction, the auxiliary pile support 20 is left in the other part, depending on the geometric shape of the support component. The auxiliary pile support 20 which is in the form of a lowering polygon shape as defined, that is, the auxiliary pile support 20 which has not shifted to the extended posture, is inside two curved envelope surfaces, and at least the lower side of these envelope surfaces In an advantageous embodiment, the envelope surface is in fact constituted by a guide track 22, which is therefore raised in a convex manner.

  Accordingly, when the auxiliary pile support 20 is arranged so that the end facing the insertion direction faces the opposite side to the printing unit 1.1 (see FIG. 1), the lower side of the guide track 22 The guide track 22 with its end facing the printing unit 1.1 and the auxiliary pile support 20 supported on the guide track 22 in the ready position are advantageously conventional for processing sheets. Is inserted into the installation space under the paper feeder of the transport / alignment device 2.4, which is lowered from the pile 2.3 toward the printing unit 1.1. reference).

  As shown in FIG. 2, the auxiliary pile support 20, shown here with only a portion of its length, is moved from a ready position supported on a guide track 22 for a defined use from a directional arrow. It moves through the guide member 23 in the insertion direction indicated by 21. As will be described in detail later, the guide member 23 is configured to keep the aforementioned area of the auxiliary pile support 20 that moves past the guide member 23 in an extended posture thereafter. The guide track 22 arranged in front of the guide member 23 is also described in detail later, so that the support member of the auxiliary pile support 20 enters the guide member 23 when it is separated from the guide track 22. 23 is attached. Thus, the guide track 22 supports the auxiliary pile support 20 at the preparation position. As is well known, the guide member 23 and the components forming the guide track 22 are here a lift chain 24 and, as an example, a guide member in order to obtain height adjustment required for non-stop operation. It is preferable to form one module that can be moved up and down by means of the auxiliary pile lifting device, in which only the guide mold 25 for guiding 23 is shown.

  3 shows an embodiment of the support part 26 of the auxiliary pile support 20 in a side view corresponding to the drawings of FIGS. 1 and 2 and from the preparation position with respect to the insertion direction of the directional arrow 21 shown. It is shown in a state toward the working position. The support part 26 is oriented in the direction of insertion of the directional arrow 21, the first joint hole 27 at the first end of the body and the second of the body facing away from the first end. And a second joint hole 28 at the end of the body. When such a large number of continuous support parts 26 are pivoted directly to each other, the above-described joint holes 27 and 28, together with the joint bolts 29 inserted therein, have joint axes parallel to each other. One rotary joint 30 and a second rotary joint 31 are formed (see FIG. 5).

  The support part 26 protrudes from the first rotary joint 30 or the first joint hole 27, that is, forms a first end of the support part 26 that faces the insertion direction indicated by the directional arrow 21 during a defined use. A first extension 32 and a second end of the support part 26 projecting from the second rotary joint 31 or the second joint hole 28, ie facing away from the insertion direction. 2 extension portions 33. The body and both extensions 32 and 33, when in a defined position, were sandwiched between two horizontal planes that were spaced apart by the design height in the highest configuration height area. A space is required, and the lower surface of the second extension 33 and the lower surface of the main body section that follows are located in the lower plane of both planes, and the upper plane includes the first The upper surface of the extension portion 32 and the upper surface of the main body portion subsequent thereto are located. The lower surface of the first extension 32 and the upper surface of the second extension 33 and the upper surface of the main body area following the second extension 33 are located in a horizontal intermediate plane extending between both planes described above. is doing.

  In order to pivot such a plurality of support parts 26 directly in series with each other, the second joint hole 28 of the support part 26 follows the support part 26 with respect to the insertion direction indicated by the directional arrow 21. The first joint hole 27 is overlapped with the second joint hole 28 of the preceding support component 26.

  Therefore, as can be seen from FIG. 4A, when the auxiliary pile support 20 is configured so as to form a rod-shaped support member at the working position, the second extension portion 33 and the second extension portion 33 are respectively followed. The body section is narrowed from both sides, and the first extension 32 and the subsequent body section are provided with a central notch 34 from the lower surface, leading the support part 26 as seen in the insertion direction 21. Can be inserted into the subsequent support component 26 until the second joint hole 28 is aligned with the first joint hole 27. Furthermore, the upper surface of the second extension 33 and the upper surface of the notch 34 are provided with contours that allow the support component 26 to assume the mutual swinging position (see FIG. 6).

  Furthermore, as can be seen from FIG. 5, the body and both extensions 32 and 33 are arranged before the respective second extension 33 of the support part 26 pivotally connected to each other, following the insertion direction indicated by the directional arrow 21. It is comprised so that it may contact from the bottom to the 1st extension part 32 of the support component 26 before this.

  Further, as can be seen from FIG. 3, the notch 34 has a through hole 35 penetrating the support component 26 at the end facing the second joint hole 28, and the second extension portion. 33 is formed at its free end with a first stopper surface 38 located in the already described intermediate plane, following the recess 36 provided to allow the support component 26 to swing relative to each other. A stopper 37 having an upper surface is provided. The distance between the stopper 37 and the second joint hole 28, the distance between the through hole 35 and the first joint hole 27, and the geometric shape of the stopper 37 and the through hole 35 are supported by the stopper 37 of the support member 26. When the parts 26 are pivotally connected to each other, they are selected so as to be able to pass through the through holes 35 of the supporting parts 26 that follow in the insertion direction.

  As can be seen from FIG. 5, the length of the first extension portion 32 is inserted when the lower surface located on the intermediate surface is in the extended posture of the auxiliary pile support 20 as described above. It is selected to abut the first stopper surface 38 of the next support element 26 that precedes it in the direction 21, thereby forming a second stopper surface 39.

  Otherwise, the geometry of the support part depends on whether it should constitute an auxiliary pile support base when it is in the working position or individual bar-like support member 20 '(see FIG. 8). ).

  A rod-like support member 20 ′ can be made with a geometric shape corresponding to FIG. 4A, whereas an auxiliary pile support base is provided by a support component 26 ′ having a geometric shape corresponding to FIG. Can be made. FIG. 4A and FIG. 4B each show the lower surface of the support component.

  FIG. 6 shows an example of a guide member in the form of a guide member 23 ', which will be described in detail, and the support of FIG. 4 (b), which is here designed to produce an auxiliary pile support as an example. The link operation with the part 26 'is shown. The guide member 23 ′ is arranged on the downstream side of the guide track 22 (not shown) when viewed in the insertion direction indicated by the direction arrow 21 (see FIG. 2). In this example, the auxiliary pile lifting mechanism described above is provided. And an upper pressing piece mechanism 23.1 and a lower pressing piece mechanism 23.2 with a horizontal gap 40 formed therebetween.

  In the configuration of the support component 26 ′ shown in FIG. 4B as an example (configuration for forming an auxiliary pile support base), the pressing piece mechanisms 23.1 and 23.2 are inserted, for example, by a directional arrow 21. The direction can be limited only to the lateral region of the support part 26 ′, or a plurality of upper and lower pressing piece mechanisms 23.1 and 23.2 can be provided for the width B of the support part 26 ′ (FIG. 4 ( b) see)) may be distributed.

  The geometry of the gap 40 is such that the first stop surface 38 of the preceding support part 26 ′ when viewed in the insertion direction is above and below while the support part 26 ′ moves through the gap 40. The pressing piece mechanisms 23.1 and 23.2 on the side are always kept in force contact with the second stopper surface 39 of the front support component 26 'before the subsequent movement in the insertion direction. Have been selected.

  In front of the gap 40, in this example, there is a horizontal alignment surface formed in the lower pressing piece mechanism 23.2. In another embodiment, this alignment surface is provided on the guide track 22 shown in FIG. It may be done. The alignment surface 41 serves to pre-align the support component 26 ′ in the extended position, after which the support component 26 ′ enters the gap 40.

  The mutual contact between the first stopper surface 38 of one of the support components 26 ′ and the second stopper surface 39 of the previous support component 26 ′ that precedes the support component 26 ′ is a gap. By being forced at 40, mutual swinging movement of the support part 26 'passing through the gap 40 and leaving the gap 40 again is prevented. Accordingly, since the auxiliary pile support 20 is separated from the gap 40 while the support part 26 'is in the extended posture, the self-supporting area of the auxiliary pile support 20 during the movement of the support part 26' is equivalent to one support part 26 '. Only get longer continuously.

  FIG. 7 shows a guide member 23 which is already shown in FIG. 2 and is configured in place of the guide member 23 ′, and here a support part 26 intended to form a rod-like support member 20 ′ as an example. The linkage with is shown.

  The guide member 23 is supported by the already described auxiliary pile lifting device instead of the pressing piece mechanisms 21.1 and 23.2 forming the stationary guide surface, and is applied to the upper surface of the rod-like support member 20 ′. In this embodiment, four clamp rolls 23.3 and two support rolls 23.4 supported by the auxiliary pile lifting device for supporting the support member 20 'on the lower surface thereof are included. Among the two support rolls 23.4, the support roll disposed upstream in the insertion direction indicated by the direction arrow 21 is while the support component 26 is displaced in the insertion direction indicated by the direction arrow 21. A large distance is provided from the other support roll 23.4 so as to be aligned in the extended posture before coming into contact with the clamp roll 23.3. Otherwise, the arrangement of the clamp roll 23.3 and the support roll 23.4 is inserted when the support component 26 moves past the guide member 23 and passes through the clamp roll 23.3. The first stopper surface 38 of the preceding support part 26 seen before in the direction is clamped by the clamp roll 23.3 and the support roll 23.4 before the second stop of the previous support part 26 seen in the insertion direction. The surface 39 is always selected so as to be kept in a forced contact state. In view of manufacturing tolerances, the clamp roll 23.3 or the support roll 23.4 is arranged and supported by the support component 26 or 26 'so that it can be turned against the return force. Is preferred.

  The auxiliary pile lifting device already described in connection with FIG. 2 further comprises a crosspiece 2.7 which can be moved up and down, which can be seen in a sectional view in FIG. 1, as shown in FIG. The end portion of the auxiliary pile support 20 facing the insertion direction shown in 21 is supported by the crosspiece 2.7 at the working position.

  As can be seen in FIG. 5 for the case where the auxiliary pile support 20 is constituted by individual bar-shaped support members 20 ′, the appropriate support is at the end in the form of the end piece 26.1 of the support member 20 ′. It is preferably performed by means of the support parts. This end piece 26.1 is configured in the same way as the support piece 26 only in the area facing the subsequent support piece 26, with the auxiliary pile support 20 being moved to the working position at the other free end. It is sometimes preferable to have a chamfer on the bottom surface that allows it to rest reliably on the crosspiece 2.7. In the region of the other end portion of the auxiliary pile support 20, the auxiliary pile support 20 coming out from the guide member 23 or 23 'in the insertion direction indicated by the arrow direction 21 after the auxiliary pile support 20 has moved to the working position. A sufficient number of support parts 26 or 26 'remain in the affected area of the guide member 23 or 23' so that the part of the body 20 is kept in the extended position. In that sense, the guide member 23 or 23 ′ forms a cradle for the auxiliary pile support 20.

  Particularly in the case where the auxiliary pile support 20 is constituted by individual bar-shaped support members 20 ′, in an advantageous embodiment, the auxiliary pile support 20 has a trailing end with respect to the insertion direction indicated by the direction arrow 21. This is connected to an endless tension means driving device in a manner not shown in detail here, and this tension means driving device adjusts the position of the auxiliary pile support 20 between the preparation position and the working position. Is called.

  Yet another advantageous position adjustment method between the preparation position and the working position is applied to the upper and lower surfaces of the auxiliary pile support 20 in the region of the guide member 23 or 23 'or just before and / or after it. A roll supported in a stationary manner, at least one of which is driven. In the case of the configuration of the guide member 23 shown in FIG. 7, for example, the support roll 23.4 on the downstream side in the insertion direction can be driven. Moreover, this type of roll drive is performed regardless of whether the auxiliary pile support 20 is an auxiliary pile support base or an individual rod-like support member 20 ', as in the tension means drive device described above. Can be used.

  When the guide track 22 is formed in an arcuate shape, a motor-operated swing lever mechanism pivotally connected to the subsequent end of the auxiliary pile support 20 may be provided as an alternative adjustment device. it can.

  It is preferable that the surface of the support component 26 or 26 ′ is configured to be able to slide along the printing body without damaging the printing body on the side in contact with the printing body.
