  • Patent number: 10723559
    Abstract: A transport mechanism and a method for transporting objects are disclosed. The transport mechanism includes a transport unit, a vacuum belt conveyor unit, and a push-type transport unit. The vacuum belt conveyor unit receives objects from the transport unit and conveys the received objects to the push-type transport unit. The vacuum belt conveyor unit can generate a vacuum force to adhere the plurality of objects thereon. When the vacuum belt conveyor unit stops conveying the objects carried thereon, the objects adhered to the vacuum belt conveyor unit would block the objects being transported by the transport unit, and when the vacuum belt conveyor unit starts to convey the objects carried thereon to the push-type transport unit, the transport unit would immediately transport more objects to the vacuum belt conveyor unit. Thus, with the vacuum belt conveyor unit, the objects are conveyed to the push-type transport unit and the position of objects is also accurately controlled.

  • Publication number: 20150114197
    Abstract: The present invention provides a composite blade module and cutting means using the same. The composite blade module comprises a blade and at least one elastic layer. The elastic layers are adhered to a part of cutting edge and/or a back of the blade selectively. The composite blade module is used by the cutting means to cut an object to be cut. The elastic layers may be used as a shock absorber to absorb the collision force acting on the blade, thus reducing the probability of breaking blade, during the cutting process. Furthermore, if the blade is broken unfortunately, the broken blade is still adhered to the elastic layers, in such a way that the broken blade is prevented from either being drawn into the cutting means and then damaging the means, or being ejected and then endangering the operator, leading to safety guarantee during cutting.

  • Patent number: 8979012
    Abstract: A winding machine includes an upper winding roller and a separation mechanism arranged at a location close to and below the upper winding roller. The separation mechanism includes a pivot shaft having an outer circumferential surface and at least one pinch arm having a connecting end coupled to the outer circumferential surface of the pivot shaft and a web engagement end extending outward from the outer circumferential surface of the pivot shaft. When the pinch arm is driven by a driving mechanism to rotate the web engagement end of the pinch arm to an engagement position where the web engagement end opposes the upper winding roller, the web engagement end of the pinch arm sucks and holds or guides a web material passing therethrough, whereby the web material is subjected to a pulling force induced by a roll of paper formed in a winding nip to tear and thus separate.
