Abstract:
The present invention provides a method for deflecting a defective cartons and mis-fed cartons on a carton print quality inspection and sorting machine. Initially the defective cartons and the mis-fed cartons are identified. If the mis-feeding is identified the extent of mis-feeding is identified. Further, for effecting these cartons, the nozzles are activated sequentially with a delay depending upon which leading portion these nozzles is arranged. This enables to use the air effectively. In case of mis-fed cartons, the air jet is sequentially operated similar to that of defective carton, but the duration for which these air flow us active depends upon the extent of overlap. Therefore, this method and the system ensure that no defective carton enter a stack of non-defective or OK cartons, making the system more reliable.
Abstract:
Control of a wrapping apparatus (600) is facilitated by enabling an operator to input a load containment force requirement and/or a minimum number of layers of packaging material (618) to be applied to a load (606), with a wrap control system (650) automatically determining wrap force and other parameters required to meet user input requirements and/or parameters to minimize the expertise required of an operator and to provide more consistent and reliable wrapping of loads (606). In addition, a wrapping apparatus (600) may be controlled to apply at least a minimum number of layers of packaging material (618) to a load (606) throughout a contiguous region (630) thereof.
Abstract:
A wrapping apparatus (1 00) and method utilize an effective circumference- based wrap speed model that dynamically controls the rate at which packaging material (108) is dispensed based on an effective circumference of a load (1 10) during relative rotation established between the load and a packaging material dispenser (1 06). The effective circumference of a load may be indicative of an effective consumption rate of the load, and may referto a dimension or size of a tangent circle (420) that is substantially centered at the center of rotation (408) of the load and substantially tangent to a line substantially extending between a first point (414) proximate to where the packaging material exits the dispenser and a second point (41 8) proximate to where the packaging material engages the load. The effective circumference of the load dynamically changes throughout the relative rotation of the load, and by controlling the dispense rate based at least in part on this dimension, fluctuations in tension in the packaging material may be reduced, often enabling containment force to be increased while reducing the risk of breakage in the packaging material.
Abstract:
The invention relates to a method for detecting the transverse position of at least one sealing section (1, 2) on a packaging material (4), in particular a film wrapping, and/or the transverse position of the packaging material (4), wherein the packaging material (4) is displaced along a running direction (L), wherein the transverse position of the at least one sealing section (1, 2) or the packaging material (4) relative to the running direction (L) is detected by means of at least one sensor unit (5). The packaging material (4) comprises at least one cursor (7) by means of which the transverse position of the at least one sealing section (1, 2) or the packaging material (4) transverse to the running direction (L) is detected, wherein the shape of the cursor (7) changes with respect to a direction running in particular transverse to or at an angle to the running direction (L), wherein said change is detected by the sensor unit (5) and the transverse position of the packaging material (4) or the at least one sealing section (1, 2) is determined by means of the change.

Abstract:
A film wrapping machine or apparatus wherein various operational conditions and data can be detected, determined, and subsequently utilized for diagnostic, operational performance, and safety characteristics, as well as for implementing improvements in operational performance so as to not only achieve optimal or predetermined performance characteristics but to also achieve economical usage of the wrapping or packaging film.
Abstract:
The present invention provides a method and apparatus for dispensing a predetermined substantially constant length of pre-stretched packaging material based upon load girth. Based upon the girth of the load to be wrapped, an amount of pre-stretched packaging material to be dispensed for each revolution of relative rotation between a packaging material dispenser and the load is determined. A rotational drive system used to provide the relative rotation is linked to a pre-stretch assembly portion of the packaging material dispenser. The linkage may be mechanical or electrical. The linkage controls a ratio of the rotational speed to the pre-stretch assembly dispensing speed, such that the predetermined substantially constant length of pre-stretched packaging material is dispensed for each revolution of the packaging material dispenser relative to the load regardless of the speed of the rotational drive. In the case of a mechanical linkage, the linkage also connects the rotational drive to the pre-stretch assembly portion such that the rotational drive also drives the pre-stretch assembly portion. 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.
Abstract:
A device for feeding cap-like seals, in particular screw-type caps (2, 2a), to a capping machine, with at least one conveying channel (6) which has a cross section matched to the shape of the seals, and therefore the seals are arranged in the said conveying channel with their seal axis (VA) transversely with respect to the conveying direction (A) in an orientation predetermined by the cross section of the conveying channel, and also means for transferring or ejecting seals (2a) out of the conveying channel that do not have the required orientation for their further processing.
