    • The present invention provides a method and apparatus for dispensing a predetermined fixed amount of pre-stretched packaging material based upon load girth. A non-rotating ring carries a belt driven by a motor. A packaging material dispenser is mounted on a rotating ring, and the rotating ring may include a pulley that connects to the band, such that the rotating ring is driven by the drive belt. Based upon the girth of the load to be wrapped, an amount of pre-stretched packaging material to be dispensed for each revolution made by the rotating ring is determined. Good wrapping performance in terms of load containment (wrap force) and optimum packaging material use is obtained by dispensing a length of pre-stretched packaging material that is between approximately 90% and approximately 120% of load girth. Once the amount of packaging material to be dispensed per revolution is determined, a ratio of rotating ring drive to final pre-stretch surface speed (i.e., number of pre-stretch roller revolution/rotating ring rotation) can be set and mechanically controlled. Thus, for each revolution of the rotating ring and dispenser, a predetermined fixed amount of packaging material is dispensed and wrapped around the load. In an alternative embodiment, the ratio is electronically controlled.
    • 本发明提供一种用于基于载荷环分配预定固定量的预拉伸包装材料的方法和装置。 非旋转环带有由马达驱动的皮带。 包装材料分配器安装在旋转环上,并且旋转环可以包括连接到带的滑轮,使得旋转环由驱动带驱动。 根据要包裹的负载的周长,确定由旋转环制成的用于每次旋转的预分配的预拉伸包装材料的量。 通过分配一定长度的预拉伸包装材料,在负载围绕(包裹力)和最佳包装材料使用方面具有良好的包装性能。 一旦确定了每转需要分配的包装材料的数量,就可以设定并机械地控制旋转环驱动与最终预拉伸表面速度的比率(即,预拉伸辊旋转/旋转环旋转数)。 因此,对于旋转环和分配器的每次旋转,将预定的固定量的包装材料分配并缠绕在负载上。 在替代实施例中,该比率是电子控制的。

    • A load portion is engaged in an infeed area and transported from the infeed area to a wrapping area with rotational, horizontal, and vertical carriers. Those carriers move the portion of the load horizontally along two horizontal degrees of freedom and one vertical degree of freedom by rotating a portion of the load about a vertical axis and translating the portion of the load along a generally linear horizontal direction and a generally linear vertical direction. The load is disengaged in the wrapping area and a stretch wrap packaging material dispenser is engaged and is transported to the wrapping area by the same rotational, horizontal, and vertical carriers to wrap the portion of the load with stretch wrap packaging material by using, once again, the same rotational, horizontal, and vertical carriers to rotate the dispenser around the load.

    • Stretch wrapping packaging material on a load includes introducing stretch wrap packaging material onto V shaped tips of projecting portions of a first grooved roller so that the packaging material spans the nonprojecting portions of the first grooved roller. The web of packaging material and the first grooved roller are transported in the direction generally parallel to the grooves. The web of packaging material spanning the nonprojecting portions of the first grooved roller is impinged with V shaped tips of projecting portions of a second grooved roller. The tips of the projecting portions of the second grooved roller are transported at a speed which is less than the speed of the tips of the projecting portions of the first grooved roller. The tips of the projecting portions of the second grooved roller moves at a speed which stretches the web between the first and second grooved surfaces in a direction transverse to the direction in which it is transported and minimizes any stretching of the web in the direction in which the web is transported. The web is stretched between the projecting portions of the first and second grooved rollers in a direction transverse to the direction in which the web is transported. The web is separated from the first and second grooved surfaces and wrapped onto a load by providing relative rotation between the load and a dispensing mechanism for the web.
    • 在负载上的拉伸包装材料包括将拉伸包装材料引入到第一带槽辊的突出部分的V形尖端上,使得包装材料跨越第一带槽辊的非投影部分。 包装材料的卷材和第一带槽辊沿着大致平行于凹槽的方向输送。 跨越第一带槽辊的非投影部分的包装材料的卷材冲入第二带槽辊的突出部分的V形尖端。 第二带槽辊的突出部分的尖端以小于第一带槽辊的突出部分的尖端的速度的速度传送。 第二带槽辊的突出部分的尖端以在第一和第二带槽表面之间沿横向于其输送方向的方向延伸纤维网的速度移动,并且使幅材的任何拉伸方向最小化, 网络被运送。 幅材在与第一和第二带槽辊的突出部分沿横向于纸幅传送方向的方向上拉伸。 网与第一和第二沟槽表面分离,并通过在载体和用于网的分配机构之间提供相对旋转而卷绕到负载上。

    • An apparatus and method for wrapping a top and bottom of a load with packaging material is provided. The apparatus includes at least one non-driven packaging material guide is provided for use in combination with a powered conveying surface. The non-powered packaging material guide includes at least one row of non-driven wheels attached to a rail. The force applied by the packaging material as it is wrapped around the guide is supported by both the rail and the at least one row of non-driven wheels. The rail also serves to bridge any gaps between the non-driven wheels, thereby preventing capture of packaging material between the non-driven wheels. Preferably, the packaging material guide includes two rows of non-driven wheels, one on each side of the rail. Further, it is preferable that the rail connect the two rows of wheels such that the two rows of wheels form an angle of 60 degrees between them. The packaging material guide is preferably positioned above the load but may also be positioned either below the load or to the sides of the load.
    • 提供了用包装材料包装负载的顶部和底部的装置和方法。 该装置包括至少一个非驱动包装材料导向器,用于与动力输送表面组合使用。 非动力包装材料导向件包括连接到轨道的至少一排非从动轮。 由包装材料围绕导向器缠绕的力施加的力由轨道和至少一排非从动轮支撑。 轨道还用于桥接非从动轮之间的任何间隙,从而防止在非从动轮之间捕获包装材料。 优选地,包装材料导向件包括两排非从动轮,一列在轨道的每一侧上。 此外,优选的是,轨道连接两排轮,使得两排轮在它们之间形成60度的角度。 包装材料导向件优选地定位在负载上方,但也可以位于负载的下方或负载的侧面。
