Gatherer stitching machine with variable chain pitch
Technical field
The present invention relates to a kind of gatherer stitching machine.
Background technology
The gatherer stitching machine of described type is known.Each folding sheets is shed, opens and collect on the obedient chain of collection from stacking branch by the continuous obedient device of folding sheets.Collect obedient chain and have a guider and one bearing of domeshape basically, the top section of this guider is configured to the crest line of tooth shape and this guider to be determined to transmit and cord, and folding sheets is transmitted with horseback riding type on this bearing.Even under the high situation of processing speed, also catch reliably and reach and take reliably and transmit equably in order to collect the folding sheets of collection on the obedient chain, collect obedient chain and have and take element, these are taken element and carry collected folding sheets in the horizontal direction.By the obedient chain of collection with take the folding sheets that device carries and transmit up to the bookbinding station by the obedient chain of collection, in this bookbinding station, folding sheets stacked on top of each other under situation through folding by means of staple.Use crimp head that is arranged on the obedient chain of collection top and the curved nail box that is arranged on the obedient chain of collection below, these curved nail boxes make the free end bending of piercing through the staple of folding sheets by crimp head for this reason.Then, the folding sheets through bookbinding continues transported to after-treatment device by the obedient chain of collection in receipts book zone.For example be that the edge cuts and receive book subsequently.
Reply has the gatherer stitching machine of single-piece collection card chain and two-piece type collection card chain and distinguishes.In the gatherer stitching machine with two-piece type collection card chain, two roller chains are provided with abreast.The obedient chain of collection half one bears the function of the obedient chain of main collection, and the obedient chain of second collection half one bears the function of the obedient chain of secondary collection.The chain vault of saddle is made of the chain crown section, and these chain crown sections are placed on the roller chain that is in right side and left side on the throughput direction.By EP 0 916 514 B1 for example known a kind of two-piece type collection card chain, wherein, the obedient chain of secondary collection only extends in the zone of continuous obedient device before the bookbinding station and the obedient chain of main collection extends across the bookbinding station along whole transmission and cord.The collection of structure card chain allows to have better accessibility and realize higher bookbinding quality thus for assembling and correction work in the zone at bookbinding station like this.
EP 881 180 B1 have described a kind of gatherer stitching machine with single-piece collection card chain.The chain vault is made up of the chain crown section, and these chain crown sections are placed on the roller chain.Take element and be arranged on regularly on the tip that collects obedient chain, thus, collect obedient chain and can construct narrowly especially.But this tolerates shortcoming: the supporting cutter that is arranged on the tip must have corresponding distance on continuous obedient device.
A kind of form of implementation of eliminating this shortcoming is disclosed among European patent application EP 1 074 495 A1.At this, take element and be fixed on movingly on the obedient chain of collection, thus, these are taken element and can swing to the position that protrudes upward basically from a position that extends laterally basically.Can make the device space that for example the ink discharge device acquisition is necessary that is arranged on the periphery and take the processing that element be there is no harm in the umbilical dystocia product thus by change in location.In addition, take element this satisfy its function and to the limit of product at folding sheets on lead.In this processing station back, there is restriction owing to taking the device swing.Therefore, product is not directly then bound or for example carry out integrity check by means of the tip thickness measure.Taking device must swing in its position that extends laterally basically in advance again.
The productivity ratio of gatherer stitching machine is not only to depend on the speed of service, but depends on this machine how many products of processing in the time of determining yet.In order under the speed situation about not raising of the obedient chain of collection, to improve the quantity of time per unit product and to improve the productivity ratio of gatherer stitching machine thus, that chain pitch and product specification is suitable.That is to say, change the distance between the device taken on the obedient chain of collection.Because the less distance of taking between the device on the less situation next part card chain of product is just enough,, productivity ratio is improved so can on the obedient chain of collection, collect more products by time per unit by correspondingly dwindling described distance.
By prior art more known be used to change the different solutions of chain pitch.Therefore, take element for example can be placed on the outer connecting plate of roller chain and can easily separate again by means of screw connection.Perhaps taking element can be placed in by means of clamping connector on the outer connecting plate of roller chain under the situation of no instrument.
In another scheme, to take element and can be configured to plastic pin, these plastic pin are plugged in the saddle section that is provided with receiver hole of the obedient chain of collection.
The problem of these solutions is, manually changes the chain pitch trouble and expends time in.Make machine and product specification cause productivity ratio low again suitable necessary downtime.
Another problem when the gatherer stitching machine that uses according to prior art is present in the zone of the receipts book apparatus of binding machine.The cutter that moves to from the below folding and the bookbinding seamed edge will be through the product of bookbinding by the release that moves both vertically.But at synchronization, product still continues to transmit by taking device in the horizontal direction.Product move both vertically and the stack of horizontal movement can cause on the product inboard taking device generation mark or printing ink dregs by what move down.
The obedient chain of disclosed collection in DE 10 2,007 053 490 A1 of gatherer stitching machine has the chain crown section and takes element, wherein, takes element and can regulate aspect its position.Therefore, take element forms the chain vault of the obedient chain of collection in non-active position a part, these are taken element and laterally stretch out and the satisfied function of taking device from the chain vault that collects obedient chain with respect to throughput direction in active position.Taking element can construct turningly and handle by control device.Control device is made up of manipulation device and controlling organization, and wherein, manipulation device fixed-site or removable and controlling organization are as the part motion of the obedient chain of collection.Manipulation device acts on the controlling organization, and thus, each is taken the position of element and can individually regulate, and promptly takes element and can be activated or deexcitation.
Be in this shortcoming, take element in the peaked area of the obedient chain vault of collection, only have one little of putting face.If this is especially thicker or than having problems under the situation of rigidity at product---these products are not to abut in all sidedly on the chain vault in peaked area.
If region generating fault at a processing station of gatherer stitching machine, the transmission section gets clogged and therefore product can not be by the obedient chain continuation of collection transmission, the element of taking that then moves forward suddenly stands load, under this load, takes that element may damage or chain also may damage.So required maintenance bothers and causes machine to stop for a long time.
Summary of the invention
