Description
技术领域
本发明涉及一种用于型坯的,特别是用于聚对苯二甲酸类塑料(PET)瓶的传送及供给单元,其中可以在传送及供给单元上游的端部处向所述传送及供给单元装载型坯,并将这些型坯供应给设置在传送及供给单元下游的端部处的输送单元。
背景技术
由DE 203 08 513 U1已知一种用于供应由热塑性塑料制成的型坯或预制件的装置,所述装置在朝向用于制造中空体的吹塑机的敞开的端部区域中具有支撑环,所述装置具有:在靠近地面处放置的用于无序地接收多个型坯的筒仓;使型坯设置在以敞开的端部指向上面的位置中并将型坯排成单排的辊式分拣机;将型坯无序地从筒仓移送到辊式分拣机的倾斜输送机;以及向下倾斜的带有在支撑环下方作用的支撑轨道的滑道,该滑道成排地接收多个敞开的端部朝上的型坯并通过斜坡重力将这些型坯供应给吹塑机,其中辊式分拣机靠近地面放置,且在辊式分拣机和滑道的抬高的上端部之间接入提升型坯的提升机。在这个装置中,从上面借助相应的倾斜装置通过倾倒在箱子中供应的型坯周期性地装填筒仓。
这个解决方案的缺点在于,型坯可能由于倾倒过程或在筒仓中撞击而受到损坏或刮擦,并且在这种情况下会产生非常高的噪音水平。
在WO2012/126129A1中记载了一种用于给输送设备装载大量部件、例如用于中空体的型坯或预制件的装置。这里,所述装置包括带有可摆动的倾斜部件的倾斜装置和用于临时存放部件的装置,用于临时存放的装置是带有可取下的覆盖件的筒仓,而倾斜装置具有机械的连接及力传递元件,所述连接及力传递元件与筒仓的可提起的覆盖件连接。在这个解决方案中,型坯也可能由于倾倒过程而受到损坏/刮擦,以及会出现高噪音水平。
发明内容
因此,本发明的目的是,提供一种装置,借助于该装置,能够以受保护和尽可能低噪声的方式和形式将型坯或预制件供应给输送设备的下游模块。
根据本发明,所述目的通过一种用于型坯的、特别是用于PET瓶的传送及供给单元来实现,在所述传送及供给单元上游的端部处能够给所述传送及供给单元装载型坯,并将这些型坯供应给设置在所述传送及供给单元下游的端部处的输送单元,其中,所述传送及供给单元具有第一传送带和第二传送带,在第一传送带下游的端部处设有漏斗式装置,型坯通过该漏斗式装置到达第二传送带上,所述第二传送带将型坯供应给设置在第二传送带下游的端部处的输送单元
因此,根据本发明的传送及供给单元不包括上游的装载装置和下游的输送单元。
在本发明的一个优选实施形式中,所述漏斗式装置截棱锥状地聚拢且具有优选竖直的出口。通过这种几何构造,所述漏斗式装置可以特别有效地以存储器或缓冲器的方式起作用,并且可以将由第一传送带供应的型坯以基本上连续的方式和形式传送到第二传送带上(即,同时存储器优选总是以最小和最大料位之间的装填状态保持被装填)。此外,通过提供所述漏斗式装置,可以省去另外的传送带并且由此节省了一定量的空间,通常为了在倾斜装置和第二(横向)传送带之间使预制件倾倒堆散开需要所述另外的传送带。
在本发明的另一个优选实施形式中,在第一传送带的区域中设有至少两个传感器(S1)和(S3),优选设有至少三个传感器(S1)、(S2)和(S3),用以检查沿第一传送带存在或不存在型坯。此时,传感器(S1)设置在第一传送带的起始区域中,而传感器(S3)设置在第一传送带的末端区域中;传感器(S2)优选布置在第一传送带的中间区域中(就是说,这些传感器分别设置在第一传送带上方的侧壁中)。这些传感器优选构造成光栅并且与(常规的)控制器相连接。
例如,如果传感器(S1)确定在第一传送带的起始区域中不存在型坯,则操控倾斜装置,以使新的带有型坯的纸箱朝第一传送带倾斜。
如果传感器(S2)确定,在第一传送带的中间区域中没有型坯,则操控第一传送带的驱动器,以提高带速。如果传感器(S3)确定,在第一传送带的末端区域中没有型坯,则适用相同的措施。
在本发明的另一个优选实施形式中,在所述漏斗式装置的区域中设有至少一个最大值传感器(S5)和最小值提供传感器(S6)以及优选设有过度装填传感器(S4),用以检查用型坯装载的料位。所述传感器(S4)、(S5)和(S6)同样也与所述控制器连接。
此时,过度装填传感器(S4)设置成略高于漏斗式装置。如果过度装填传感器(S4)确定,在该传感器的区域中存在型坯,即漏斗式装置被过渡装填(即,被装填到超出边缘),则关闭第一传送带。
最大值传感器(S5)设置成略低于漏斗式装置的边缘。如果最大值传感器(S5)确定,在该传感器的区域中存在型坯(即,达到最大料位),则必要时降低第一传送带的速度。
最小值传感器(S6)设置在漏斗式装置的竖直出口的下端处。如果最小值传感器(S6)确定,在该传感器的区域中不再有型坯,则低于最小料位并触发警告消息。必要时,也可以提高第一传送带的速度和/或使另一个带有型坯的纸箱朝第一传送带倾斜(即,根据传感器(S1),(S2)和(S3)的指示)。
在料位处于最大值传感器(S5)和最小值传感器(S6)之间时,存在基本上连续的运行。这是所希望的正常运行。原则上可以考虑省去传感器(S4)。
在本发明的另一个优选的实施形式中,在第二传送带的区域中设有至少一个另外的传感器(S7),用于检查第二传送带上存在或不存在型坯,该传感器同样与所述控制器连接。该传感器(S7)在漏斗式装置的下方设置在第二传送带的侧壁中。如果传感器(S7)在其区域中没有检测到型坯,且同时传感器(S6)指示存在型坯,则可能在第二传送带和漏斗式装置或竖直通道之间出现桥接并且存在堵塞情况。据此产生警报信号并必须由操作人员手动清除堵塞。
在本发明的另一个优选的实施形式中,所述传感器(S1)至(S7)构造成光栅。由此可以以简单且可靠的方式检测在相应的区域中存在或不存在型坯。
在本发明的另一个优选实施形式中,第一传送带构造成软带。以这种方式,在向第一传送带上倾倒时避免出现对型坯的损坏/刮擦,且附加地降低了噪音。同样第二(横向)传送带也可以相应地构造成软带。软带优选由软塑料材料制成或用软塑料材料涂覆。
在本发明的另一个优选实施形式中,第一传送带和第二传送带彼此成直角设置。以这种方式,也可以在设备构造中节省空间。
在本发明的另一个优选实施形式中,在第一传送带的上方以及在漏斗式装置的上方能设置一个或多个覆盖件。所述覆盖件是出于卫生原因而设置的并且应保护型坯免受灰尘和其他颗粒的影响。这里,所述覆盖件可以设计成可翻起的和/或可拆卸的。
在本发明的另一个优选实施形式中,在第一传送带上游的端部处设置有斜面。所述斜面优选由塑料材料形成,并且对通过倾斜装置对第一传送带进行的装载提供辅助,就是说,不会由型坯留在第一个传送带的前面。
优选在第一传送带和漏斗式装置之间的交接区设置另一个斜面。该斜面优选由塑料制成且确保没有型坯在此停留。
在本发明的另一个优选实施形式中,第一传送带的长度在1800mm至2200mm之间,优选为约2000mm。通过使用根据本发明的漏斗式装置(或存储器),利用较短的第一传送带长度即可满足要求。尤其是不需要为了考虑到要实现尽可能地连续的运行而在第二(横向)传送带前面将型坯的集合充分地分开而设置连接到第一传送带上的附加的传送带。

第一传送带5将型坯运送到漏斗式装置或存储器6(在当前情况下,在漏斗式装置6上设置覆盖件6a,并且在第一传送带的后部上设置覆盖件5a)。
从这里出发,型坯到达第二传送带7(这里第二传送带由漏斗式装置6或其覆盖件6a覆盖),第二传送带将型坯传送给提升机8。在提升机8后面连接具有回输带9a的常规辊式分拣机9。
在辊式分拣机9的下游设置有供给单元10,所述供给单元将型坯转交给夹紧输送机11的检查和抛出单元的入口星形结构,在这里将型坯分成单个的。在夹紧输送器11后面例如还连接有输出轨道12,通过所述输出轨道将型坯引入这里仅示意性示出的拉伸吹塑机13中。
图2现在示出根据本发明的传送及供给单元4的透视图,其中部分剖开地示出漏斗式装置6,并且仅示意性地示出了第二传送带7(第二传送带在图5中单独描述)。
具有加高侧壁15a的、安装在侧壁15上的格栅部件15b和第一传送带5上游的端部处的斜面14的区域应与图1中所示的倾斜装置3配合作用,使得给第一传送带5装载型坯时型坯不会侧向跌落或没有型坯留在倾斜装置3和第一传送带5之间的交接区处。
在根据本发明的传送及供给装置4中,型坯从倾斜装置3到通常构造成软带的第一传送带5的下落高度优选小于100mm,从而型坯不会由于倾倒过程而受到损坏/刮擦并且可以保持噪音水平较低。
在倾倒过程之后,借助于第一传送带5沿传送方向T1上将型坯带到漏斗式装置6处。第一传送带5由驱动器18驱动并由支架19承载。用于第一传送带5和漏斗式装置6的图1中所示的覆盖件5a、6a的支座16在侧壁15之间延伸。
在第一传送带5和漏斗式装置6之间的交接区处也设有斜面17,该斜面确保型坯不会在这里停留。然后型坯进入漏斗式装置(或存储器)6,在确定的启动时间之后型坯开始装填漏斗式装置,并在确定停留时间之后通过竖直的出口6b重新离开漏斗式装置(缓冲或储存功能)并落到第二传送带7上。
第二传送带7沿传送方向T2(即垂直于传送方向T1)将型坯输送到图1中所示的提升机8。漏斗式装置6由支架20支承。
参考图3特别是说明传感器S1、S2和S3沿第一传送带5的的布置以及其工作原理。
可以看出,传感器S1设置在第一传送带5的起始区域中,传感器S2设置在第一传送带5的中间区域中,传感器S3设置在第一传送带5的末端区域中(即,分别在第一传送带5的上方设置在侧壁15中)。传感器S1、S2和S3优选构造成光栅并与常规的控制器连接(未示出)。
如果传感器S1确定,在第一传送带5的起始区域中不存在型坯,则相应地操控倾斜装置3,以将带有型坯的新的箱向第一传送带5上倾倒。
如果传感器S2确定,在第一传送带5的中间区域中没有型坯(并且传感器S1被占用),则操控第一传送带5的驱动器18并提高带速度。如果传感器S3确定,在第一传送带5的末端区域中没有型坯(并且传感器S1和/或S2被占用),则适用同样的处理方式。
此外在漏斗式装置6的区域中设置传感器S4(过度装填传感器)和S5(最大值传感器),过度装填传感器S4在斜面17的附近设置在侧壁15中并且略高于斜面14的上边缘(就此参见图4)。
在传送方向T1上观察,最大值传感器S5设置在过度装填传感器S4后面的一段距离处并且略低于斜面17的下边缘(就此参见图4)。
第一传送带5的长度L1为1500mm至2500mm,优选为约2000mm,宽度B1约为1700mm。漏斗式装置6的长度L2约为1660mm,宽度B2约为1720mm。
参考图4特别是说明了传感器S4、S5和S6在竖直方向上沿漏斗式装置6和竖直的出口6b的布置及其功能原理。
过度装填传感器S4设置在侧壁15中并且略高于斜坡14的上边缘,就是说,特别是也高于漏斗式装置6的上边缘。过度装填传感器S4指示漏斗式装置6的过度装填状态。
最大值传感器S5设置在漏斗式装置6的下侧上并且略低于斜坡17的下边缘。最大值传感器指示漏斗式装置6的最大料位。
最小值传感器S6设置在竖直的出口6b的侧壁中。最小值传感器S6指示漏斗式装置6的最小料位。
传感器S4、S5和S6同样与所述常规控制器相连。
如果最大值传感器S5检测到其区域中存在型坯(即,达到最大料位),则必要时降低第一传送带5的速度,因为可能出现过度装填。
但如果尽管如此过度装填传感器S4仍确认在其区域中存在型坯,即漏斗式装置6被过度装填(即,用型坯装填至超过边缘),则关闭第一传送带5。
如果第一传送带5由于传感器S4检测到过度装填状态而被关闭,则优选一直等待到型坯的料位再次下降到最大料位以下,然后再次接通第一传送带5并且接着供应新的型坯。
如果最小值传感器S6确认在其区域中不再存在型坯,即低于最小料位,则最小值传感器触发警告消息。
必要时,提高第一传送带5的速度和/或使另一个带有型坯的箱朝第一传送带上倾倒(即,根据传感器S1、S2和S3的指示)。
在料位处于最大料位(传感器S5)和最小料位(传感器S6)之间时,则存在根据本发明的传送及供给单元基本上连续的运行。这就是希望的正常运行状态。
在漏斗式装置6的下方设置第二传送带7,所述第二传送带将型坯传送到下游的输送单元8(参见图1)。下面结合图4描述传感器S7的布置和工作原理。
从竖直的出口6b的下边缘到第一传送带5的高度H1在240mm至320mm之间,优选约为280mm。从第二传送带7到竖直的出口6b的下边缘的高度H2小于约300mm,优选小于200mm。
在图5中,现在说明带有壳体22的第二传送带7。如上面在图4中示出的那样,具有垂直于第一传送带5的输送方向T2的第二传送带7安装在漏斗式装置6或竖直的出口6b的下方。这里,上部的壳体开口23与竖直的出口6b对齐。
第二传送带7的驱动器21设置在后面的侧壁26下游的端部处。在壳体22的上侧上设有可翻起的观察及检查窗口27。第二传送带7在当前情况下不是在壳体22的整个长度上延伸。壳体22的后端部区域24不再包括带部段;因此,第二传送带7上游的端部通常通过活门与端部区域24分开。
在前面的侧壁25中,优选在壳体开口23的区域中,设有另一个传感器S7,该传感器同样构造成光栅的形式并与所述常规控制器相连。
传感器S7用于检查第二传送带上存在或不存在型坯。如果传感器S7在其区域中未检测到型坯并且同时传感器S6指示存在型坯,则在第二传送带和漏斗式装置或者说竖直的通道之间可能发生桥接并且存在堵塞。据此产生警报信号,并且必须由操作人员手动清除堵塞。
