Abstract
本发明涉及用于排出页张的装置,特别是涉及用于从加工页张的机器的输送路段中排出页张以将该页张存放在辅助叠堆上的装置,本发明提出,在传送方向上来看,所述页张能够借助收纸辊在主页张叠堆之前从输送路段排出并且借助抽吸带传送***以及配属于该抽吸带传送***的抽吸带减速***延缓地存放在辅助叠堆上,其中,抽吸带传送***和抽吸带减速***布置在辅助叠堆的上方。
Description
技术领域
本发明涉及一种从加工页张的机器、例如模切机或印刷机的输送路段中排出页张的装置。
背景技术
在模切机或印刷机的收纸装置中,页张依次输送到页张叠堆并且存放在这个页张叠堆上。
已知了一种收纸装置,其中页张在存放在页张叠堆上之前从输送路段中来排出并且存放在辅助叠堆上。
DE 10 2008 006 528 A1示出了一种用于从在印刷机的印刷装置和页张叠堆之间的输送路段中梳去页张的装置,其中梳去的页张借助使页张减速的传送带输送到辅助叠堆。
DE 198 19 491 C1示出一种收纸辊,该收纸辊借助抓取***从输送路段中接收页张并且不使这个页张减速地输送到页张叠堆***或存放***。
发明内容
本发明的目的在于,提出一种具有收纸辊的用于从加工页张的机器的输送路段中排出页张的装置,借助该装置可以把页张减速地输送到辅助叠堆。
根据本发明,该目的通过权利要求1的特征来实现。
本发明的特别的优点是,即在存放在辅助叠堆之前使页张减速。通过这个措施可以实现精确的叠堆形成,这种叠堆形成使得精确的进一步处理成为可能。
一个特别的优点是抽吸带制动器的使用,其中设置多个(至少2个)并排地布置的、被驱动的抽吸带,所述抽吸带吸住由废页辊从输送路段中排出的页张的后边缘并且将该页张制动至小的收纸速度。
用于抽吸带的正弦走向的驱动曲线实现了使页张从高加工速度减速到低的收纸速度。
在此,抽吸带制动器布置在页张的上方,从而这个抽吸带制动器从上方作用于页张。
在从属权利要求中说明了其他有利的改进方案。
附图说明
本发明的实施例在附图中示出并且在下面进行说明。附图中
图1以示意性截面图示出页张轮转印刷机,
图2以示意性截面图示出加工页张的机器的收纸装置的截面,
图3示出收纸辊和布置在下游的存放***的俯视图。
具体实施方式
在根据图1的实施例中,加工页张7的机器、例如印刷机1或模切机具有进纸装置2、至少一个印刷装置3或4以及收纸装置6。页张7从页张叠堆8中被取出和分成单张或者鳞片状地通过输送台9输送到印刷装置3和4。这些印刷装置以已知的方式各包含一个印版滚筒11,12。印版滚筒11和12各具有一个用于固定柔性印版的装置13,14。此外,给每个印版滚筒11,12配置一个用于半自动地或全自动地更换印版的装置16,17。
页张叠堆8平放在能够可控地升降的主叠堆板10上。借助所谓的抽吸头18从页张叠堆8的上面取出页张7,该抽吸头特别是具有多个用于将页张7分成单张的升降式抽吸装置和牵引式抽吸装置19,21。此外,设置鼓风装置用于使跟踪页张叠堆的探测部件的上部页张层松散。为了使页张叠堆8、特别是页张叠堆8的上部的页张7对齐,设置多个侧面的和后部的止挡。
收纸装置6具有输送路段22,该输送路段包括具有抓取器桥24的用于把页张传送到收纸装置6的主页张叠堆26的抓取器链式***23。
沿页张输送方向在主页张叠堆26前面,在由抓取器链式***23限定的输送路段22下方设置有一个用于从输送路段22排出页张的装置。这个装置主要包括页张输送辊27,该页张输送辊构造为收纸辊,该收纸辊具有至少一个用于从抓取器链式***23的抓取器桥24接收页张的抓取装置28。抓取装置28抓取页张的前边缘并且把这些页张传送到相邻于收纸辊27布置的辅助叠堆29。设置了用于正确地形成叠堆的装置、例如止挡31。
收纸辊27具有轴向上彼此间隔的通道41,抽吸带42沉入所述通道中,以便抽吸页张的朝向收纸辊27的一侧并且将该页张输送到辅助叠堆29。
抽吸带42延伸直到辅助叠堆29上方。
分别借助于配属给每个抽吸带42并且布置在辅助叠堆29上方的抽吸箱44给布置在抽吸带42中的抽吸口43供应抽吸空气,该抽吸箱与负压源连接。驱动轴46、以及用于抽吸带42的转向滚子45支承在抽吸箱44中。驱动轴46被以加工页张的机器的节拍或者由辅助电动机来驱动。
分别在抽吸带42的侧面同样在待收取的页张的上方布置减速装置32。
为了能够将需从输送路段22中排出的页张以相对于加工速度减小的收纸速度传送到辅助叠堆29上,给收纸辊27配置抽吸带制动装置32。根据图3,抽吸带制动器32主要包括具有至少两个彼此间隔地布置的能由电动机驱动的抽吸带33a至e的抽吸带装置,所述抽吸带布置在一个公共驱动轴36上。驱动轴36由电动机37驱动。驱动电动机37以正弦速度曲线35对驱动轴36进行驱动,因此能够将在加工页张的机器的加工速度下由抽吸带制动器32接收的页张减速到收纸速度。
基于信号、例如根据在线检验排出的页张由废页辊27以页张传送速度转送到抽吸带42上。在此,页张在该页张的前部区域中由抽吸带42部分地保持。在页张的后部区域中,页张由动态的页张减速装置33a-e吸住并且减速。页张减速装置33的保持力高于页张前部区域中的抽吸带保持力。由此,页张在减速过程中平缓地从抽吸带42分离。
在页张的后缘上,下压件48以加工页张的机器的节拍向下运动,以便把页张在该页张的后缘上向下输送到辅助叠堆29上并且防止了页张的后缘与后续的页张接触。
为了确保同步地接收,抽吸带42布置在废页辊27的圆周之内。
用于废页辊抓取装置的操纵轴以有利的方式具有四活节47。
