  • Patent number: 9371145
    Abstract: A control device for a tubular material package is provided which achieves control of a tubular material package by the effective cooperation of relays (44), sensors (27) and a controller (60). All of the relays have an ON state and an OFF state and are connected to the controller, and each relay is connected to a corresponding component. The sensors are distributed on the components, and capable of detecting and identifying the current state of an object to be detected; all of the sensors are connected to the controller and send sensing information to the controller. The controller comprises electronics and a control program, and is capable of receiving the information from the sensors and sending instructions controlling the relays. The control device is used in a packing machine for tubular materials.

  • Patent number: 9090368
    Abstract: A splicing type unloading device, which is used for a pillow-type automatic packaging machines for tubular material, includes a discharging device having a row of discharge orifices for discharging well packaged bags respectively, a plurality of holding devices aligned side-by-side below the discharging device, a splicer inclindedly positioned below the holding devices to be horizontally moved, and a conveyor belt positioned below the splicer. An inlet of the splicer is positioned above an outlet thereof to serve as a slider. The splicer is horizontally moved to align the inlet thereof right below the discharging device for the packaged bags being downwardly dropped from the holding devices to the inlet. The splicer is then horizontally moved to align the outlet thereof with the conveyor belt for transferring the packaged bags from the splicer to the conveyor.

  • Publication number: 20130203574
    Abstract: The present invention relates to a lower sealing and cutting device for tubular material packaging, and more particularly relates to a packaging device of pillow-type packaging. Compared with other pillow-type packaging methods for tubular material, the existing pillow-type packaging method for flaky materials has the disadvantages of wasting material which affects appearance, increased the price, adding additional working procedures, increased energy consumption, and high labor costs. The present invention is to provide a lower sealing and cutting device for tubular material packaging in which a new open-end is automatically formed and always kept in an opened state, while one by one a plurality of tubular materials form a packaging bag. According to the present invention, the open-end of the tubular material penetrates from the underside to the upside of the inner support pit, wherein the inner support with an upward top-end is within the tubular material.

  • Publication number: 20130196838
    Abstract: The present invention relates to an open-end shaped retaining device for tubular material packaging, and more particularly relates to a packaging device for pillow-type packaging. Compared with other pillow-type packaging for tubular material, the existing pillow-type packaging method for flaky materials has the disadvantage of wasting material which affects appearance, increases the price, adds additional working procedures, increases energy consumption, and raises labor costs. The present invention provides an open-end shaped retaining device for tubular material packaging in which an internal support pit is arranged on an inner support seat. Each internal support pit has an opening at the top and a channel at the bottom.
