The invention relates to a method and to a device for producing packaging units in a bag forming, filling and sealing machine, products (18) combined into an amount of products being transferred from a portion container (17) into a product transfer device (10) for transferring the amount of products to a product filling device (19), the product transfer device having a product carrier (21), which is guided on a movement path, and a product guiding device (22), the product carrier, once the amount of products has been transferred from the portion container into the product guiding device, performing an accelerated movement out of a product pick-up position P1 of the product carrier so as to compress the amount of products between the product pick-up position P1 and a product transfer position P2 for transferring the amount of products into the product filling device.

A distribution station includes a mobile trailer, a pump on the mobile trailer, a manifold on the mobile trailer and connected with the pump, a plurality of hoses in communication with the manifold, and a plurality of valves on the mobile trailer. Each of the valves is situated between the manifold and a respective different one of the hoses. Each of a plurality of fluid level sensors is associated with a respective different one of the hoses. The fluid level sensors are operable to detect respective different fluid levels. A controller is configured to operate the valves responsive to signals from the fluid level sensors, activate and deactivate the pump, identify whether there is a risk condition based upon at least one variable operating parameter, and deactivate the pump responsive to the risk condition.

A method and apparatus are provided for operating a refueling station including source tube-trailers and at least one compressor to reduce refueling cost. The refueling station includes a gaseous fuel supply source including a plurality of tanks on a tube trailer coupled to a first control unit, and high pressure buffer storage having predefined capacity coupled to a second control unit and the first tanks by a pressure control valve and the first control unit, and at least one compressor. The refueling station is operated at different modes depending on a state of the refueling station at the beginning of each operational mode. The refueling system is assessed at the end of each operational mode to identify the state of the system and select a next mode of operation. The operational modes include consolidating hydrogen, or any gaseous fuel, within the tubes mounted on the trailer.

An automatic staged object feeding and discharging system includes a table, feeding device, staged feeding and discharging device and robotic arm; the staged feeding and discharging device has a feeder and distributing device in such a way to adjust a feeding and discharging angle of the distributer in a two-stage manner upon object feeding and discharging, allowing the robotic arm to grip material pieces conveniently, thereby decreasing the cost and increasing the processing speed.

Provided are a method and an apparatus for extruding into a tube and filling the tube at a high speed and simultaneously sealing the tube. Specifically provided is a method for producing a polymer tube, containing a liquid therein and being sealed at constant intervals, the method including an extrusion step of continuously melt-extruding a polymer material through a die into at least one tube, while feeding a liquid into the tube to obtain at least one liquid-containing tube; and sealing step of discontinuously pressing the at least one liquid-containing tube between a pair of pressurizing members at constant intervals to cause pressure-bonding before the tube solidifies, while continuously taking up the extruded tube.

A vertical packaging machine that includes a forming tube having an inner passage section and retaining means associated with the forming tube. The retaining means includes a retaining device configured to be displaced between a blocking position (P1) in which it at least partially blocks the inner passage section of the forming tube, and a release position (P2) in which it does not block said inner passage section of the forming tube. While in the blocking position (P1), the retaining device is arranged at a fixed specific height and is configured to prevent a product from passing through the inner passage section of the forming tube. Upon transitioning to the release position (P2), the retaining device is withdrawn from the path to be followed by the product.

A tubular bag machine having a longitudinal sealing element having two transverse sealing jaws which are moveable against each other to transversely seal a film tube, having a mechanism which moves the transverse sealing jaws, a filling device for filling the unsealed tubular bags with a filling material, a separating element for separating individual filled tubular bags, a dosing device disposed upstream of the filling device, and a transfer element having several transfer containers between the filling device of the tubular bag machine and the dosing device. The filling material is transferred from the dosing device to the transfer containers, and the transfer containers are transported to a dispensing station along a transfer line, and the filling material is transferred to the filling device, and the transfer containers are transported back along a return transfer line.
