摘要： A packaging machine that has features for feeding a web in the form of a continuous chain of bags through the machine while helping maintain the web in proper alignment and proper tension, and having additional features for improved loading of the bags. The improved web feed includes a dancer assembly equipped with a pair of nips that are driven at speeds responsive to the rate of web travel through the machine so that tension between a web supply and the dancer nips is isolated from the downstream portions of the web. A web feed mechanism which automatically threads the web through baggers is also provided. The web feed mechanism includes elastic belts which frictionally grip the web to isolate the tension in the section between the dancer nips and the belts from the tension of the web feed mechanism. Nips adjacent the load station and at the downstream end of the web feed mechanism have surface speeds exceeding the surface speed of the belts to maintain tension on the web through the web feed mechanism and effect a slight pre-opening of the bags before they are delivered to the load station. Other features include a cantilevered support of the web supply and bagger, a bagger support which functions as a plenum, an improved dancer assembly, and improved application of compressed air for bag opening.

摘要： A packaging machine that has improved features for feeding a web in the form of a continuous chain of bags through the machine while helping to maintain the web in proper alignment and proper tension, and having additional features for improved loading and sealing of the bags. The machine includes a jam prevention device having a prime mover driven damping sub-assembly which includes a seal bar and a reciprocatable seal pad and housing. The housing is spring-mounted on the clamping sub-assembly in a lost motion arrangement. Movement of the seal pad toward bring a loaded bag into contact with the heater bar sub-assembly is aborted if a sensor detects premature lost motion movement of the pad. Control structure either allows or disallows the sealing process to continue based upon sensor signals.

摘要： A jam prevention device comprises a light beam source that emits a light beam and is located on a main frame structure of a packaging machine in the machine's sealing section. During operation, the light beam is reflected off two reflective surfaces located on a moveable support operably connected to a prime mover. The reflected beam is received by a receiver located opposite the source. A clamping sub-assembly includes a seal bar and a reciprocatable seal pad housing. The housing is spring-mounted on the clamping sub-assembly and substantially surrounds the seal bar. The reflective devices are mounted on the housing. The prime mover moves the clamping sub-assembly towards a heater bar sub-assembly. The housing defines two cavities for receiving the reflective devices. The movement of the clamping sub-assembly brings a loaded bag into contact with the heater bar sub-assembly for the purpose of effectuating a seal of the bag. The pressure applied by the clamping sub-assembly during the meeting of the clamping sub-assembly and the heater bar sub-assembly causes the housing to move during the sealing process thereby moving the reflective devices into the cavities and disrupting the light beam. A photo-sensor is provided for detecting the reflection of the light beam during the sealing process as just described. Control structure either allows or disallows the sealing process to continue based upon detection of the light beam.
摘要翻译：阻塞装置包括发射光束并位于机器密封部分中的包装机的主框架结构上的光束源。在操作期间，光束从位于可操作地连接到原动机的可移动支撑件上的两个反射表面反射。反射光束由与光源相对的接收器接收。夹紧子组件包括密封条和可往复运动的密封垫壳体。壳体弹簧安装在夹紧子组件上并且基本上围绕密封条。反射装置安装在壳体上。原动机将夹紧子组件移向加热棒子组件。壳体限定用于接收反射装置的两个空腔。夹紧子组件的运动使装载的袋与加热棒子组件接触，以实现袋的密封。夹紧子组件在夹紧子组件和加热棒子组件的会合期间施加的压力导致壳体在密封过程期间移动，从而将反射装置移动到空腔中并破坏光束。提供光敏传感器，用于在刚刚描述的密封过程期间检测光束的反射。基于光束的检测，控制结构允许或不允许密封过程继续。

摘要： A process of forming dunnage is disclosed. A chain of interconnected plastic pouches (38) are fed along a path of travel to a fill and seal station (24). The pouches (38) are sequentially opened as each pouch is positioned in the fill station. Each pouch is opened by directing a flow of air through a pouch fill opening (50) to separate a face (46) from a back (48) of each such pouch and continuing the flow of air through each such opening to inflate each opened pouch. Each such inflated pouch is then sealed to create hermetically closed and inflated dunnage units (56). Novel web and dunnage units are also disclosed.

摘要： A packaging machine and method of packaging utilizing chains of interconnected preopened bags which are fed sequentially and one at a time to a load station. Bag tops are clamped against spreading horns by sensor equipped clamps which cause disablement of a bag filling mechanism unless a bag is properly located at the load station. A bag spreading and transfer mechanism spreads a loaded bag and transfers it to a bag closure station for sealing. The mechanism includes bag-supporting structures for supporting the bag during loading transfer and sealing and for expelling a completed package from the machine.

摘要： The present invention concerns a machine for converting a web of preformed pouches to dunnage units. The pouches are defined by transverse seals that extend from a remote edge to within a predetermined distance of an inflation edge. In a first embodiment, the machine includes a guide pin, a drive, a blower, and a sealing element. The guide pin is insertable between the transverse seals and the inflation edge. The guide pin defines a path of travel of the web. The drive moves the web along the path of travel. The blower is positioned with respect to the path of travel for inflating the preformed pouches. The sealing element is positioned to provide a longitudinal seal that intersects the transverse seals to close the preformed pouches and form inflated dunnage units. The disclosed examples of machines for converting a web of preformed pouches to dunnage units including various improvements to existing machines.
