Definitions
- the book block blanks created in this way are removed by hand from the outlet of the collating machine, stacked on pallets and fed the filled pallets to a thread sewing machine, unstacked by hand and bound in a thread sewing machine to the book block blank in a manner known per se. From this description of the known method for producing a book block, it becomes apparent that, despite the use of a collating machine, a great deal of manual work is required and a great deal of idling results from the intermediate stack formation. The intermediate batch formation also requires a lot of space and working time. In addition, the collating machine cannot be fully utilized in all cases, for example if fewer layers are collected than existing magazines for the book block.
- the gathering of folded layers and stitching of the collected layers into magazines or the like with the so-called saddle stitcher is known.
- the saddle stitcher has magazines that are each filled by hand with the same folded printed sheets.
- a layer is pulled from the magazines with investors and placed on the means of transport running across the front of the investors.
- the means of transport consists of a saddle on which the layers are hung. To do this, the layers have to be opened, which is automatically carried out by the investors mechanically or with suction air.
- the open layers belonging to a magazine are brought together in a roof shape on the saddle and fed directly to a thread or wire stitching machine, in which the layers collected are thread or wire stitched on the saddle.
- the object of the invention is to provide a much more efficient method for producing book blocks, preferably essentially using known devices, and an apparatus for carrying out the method.
- the third group begins with the third layer and the fourth group with the fourth layer, preferably the magazines of the transport system are filled in this order, so that the feeders transfer the layers in this order to the transport system, which thus transports each layer individually rt.
- every first layer of a group of the same, e.g. the first thread sewing machine, and each subsequent layer is fed to the thread sewing machine, which subsequently requires this layer in the book block.
- the invention further relates to a device for carrying out the method according to the invention, consisting of a magazine, feeder and a collating device having a transport system cooperating with the feeders and a thread sewing machine, characterized in that the collating device is combined with at least one further thread sewing machine such that the collating device 1 is designed such that - groups with f-layers f each can be created and the layer following a layer of a 1 group is the layer x + -, where f is the number of folder stitching machines and greater than 1, 1 the number of layers, x the ordinal number of the position of the book block 1 and the quotient - an integer, preferably f is an even number, and that in each case the same position in the sequence can be fed to a group of the same thread sewing machine.
- a gathering machine known per se is preferably combined with a plurality of thread sewing machines known per se in such a way that a switching device is arranged between the transport system of the gathering machine and each thread sewing machine, which enables a position to be passed on to the predetermined thread sewing machine.
- the magazine feed transport system of a saddle stitcher known per se is used and combined with at least two thread sewing machines.
- the layers are hung open on the saddle in the known manner and with the switch device a saddle from the respective company the stapling machine.
- the thread sewing machine staples the layers belonging to a book block together and pushes the stapled book blocks onto a known collection tape. They are fed from the collecting belt into a bookbinding machine known per se.
- these are preferably arranged in the thread sewing machine above a folding sword, which takes care of the last fold and at the same time serves as the saddle of the thread sewing machine.
- the invention thus offers a direct flow from collating or collecting to creating several book blocks simultaneously. It is particularly advantageous that this flow does not have to be interrupted even if stopper arches or the like occur; because in such a case the following sheets of the following group can be led into an emergency display with the switch system.
- the thread sewing machine in question is no longer loaded and / or the associated feeders are switched off during a cycle, that is to say in the following, for example six cycles.
- the investors continue to work according to the set program.
- at most a few layers only migrate to the emergency delivery, so that there is little waste.
- the stopper sheet fall is simulated in the example given, for example if the tenth layer for thread sewing machine 5 (10 5 ) fails.
- the invention ensures uniform utilization of all thread sewing machines.
- the spacing of the layers is generally selected so that the switch system can branch off the respective layer for the predetermined thread-stitching machine without interrupting the transport.
- the layers required for stitching are collected on a saddle in the usual way before thread sewing, that is to say after branching.
- it is possible to use fewer stapling machines if the performance of these machines allows it and, if necessary, to partially collect or collect them on the means of transport, i.e. to lay several layers on top of each other.
- the method according to the invention and the new device work particularly effectively if they work together with methods and devices for the direct production of book blocks, as are proposed in DE-A-2 741 332, 2 851 257 and 2 905 358.
- the device according to the invention has the transport system 1 of a saddle stitcher. This is equipped with twenty-four magazines 2 arranged in series and with twenty-four feeders 3 interacting with the magazines.
- the feeders 3 pull a layer from their magazines, if necessary open them in a manner known per se and hang the opened individual layer on the saddle (not shown) of the transport chain.
- the individual layers are transferred from the saddles of the transport chain to downstream saddles 4 of the switch system 5.
- the switch system 5 has a branch 7 for each thread sewing machine 6, with which the respective position of the predetermined thread sewing machine 6 is fed.
- Each thread stitching machine 6 preferably collects four layers on a saddle, staples them and connects them to the previous four stitched layers until the book block 8 is complete.
- the stapled book block separated from the following book block is placed in the preferably scaled book block row 9 and the book blocks are placed on a collecting belt 10, on which they are individually passed on in a row in a row to a book binding machine 11 and processed there.
- the device shown is essentially a new combination of commercially available machines. Only the switch system 5 with the emergency delivery 18 is a new machine element.
- FIGS. 2a and b schematically show an example of a folding sword saddle which is used to staple layers 15 with no last break or fold.
- These layers are, for example, individually supplied on the conveyor belt of the switch system 5 with a commercially available collating machine, branched off and brought against the stop blade 17 up to the folding sword 12.
- the sword 12 which also serves as a saddle for sewing thread, travels upward in the direction of the arrow through two folding rollers 13 loaded with springs 14 and arranges the last fold of the position.
- the needle 16 is stapled in a manner known per se.
- This variant of the method according to the invention is particularly economical because it is no longer necessary to open the layer before stapling. A simpler pre-folding machine can also be used.
