A transportation device (10) comprising crank arms (22) installed rotatably on a drive wheel (21), link levers (23) each having one end pin-connected to the tip of each of the crank arms (22), and swing parts (30) each having the other end pin-connected to each of the link levers (23) and held at a specified distance from a rotating shaft (210) of the drive wheel (21), wherein a speed changing cam roller (223) is installed on the crank arm (22) projectedly at a position apart from the rotating center thereof, and the transmission cam roller (223) is engaged for guiding with a transmission cam groove (44) formed eccentrically with respect to the rotating shaft (210) of the drive wheel (21), whereby the tips of the crank arms (22) are swung with in one rotation frequency of the drive wheel (21), and the angular velocities of the link levers and the swing part (30) connected thereto are increased or decreased periodically relative to the angular velocity of the drive wheel (21).

The invention, which relates to the micro/nano particle operation technology, relates to a micro/nano particle transfer method having micro force sensing and liquid drop self-calibration functions, and an apparatus for realizing the same. Therefore, a problem that capillary force detection can not be realized by using the existing capillary-force-based micro/nano particle transfer method can be solved. According to the method, one operating liquid drop is allocated at a micro/nano particle to-be-released position; an operating probe having a micro force sensing function is used for dipping and taking the liquid drop, the operating probe is moved above the micro/nano particle, and picking up of the micro/nano particle is realized by the capillary force for picking up the liquid drop; and the operating probe is moved to a to-be-released position and releasing of the micro/nano particle is realized by using the capillary force for releasing the liquid drop. According to the invention, the liquid bridge capillary force during the micro/nano particle transfer process can be detected in real time and the precision is at an nN order; on the basis of the self-calibration characteristic of the capillary force and the liquid drop, reliable releasing of the micro/nano particle can be realized; and a proper liquid drop operating condition can be created by controlling the speed of liquid drop dipping by the probe and changing the structural morphology of the end effector.

The invention relates to a workstation (1) of a textile machine for creating cross-wound spools. The workstation comprises a creel (11), pivotably mounted for holding a winding spool (5) in a rotatable manner; a roller (34), the winding spool (5) abutting the roller during winding; and a wire suction means (21), which can be applied with a negative pressure as required to pick up a veil travelled onto the surface of the winding spool (5) after interruption of the winding. According to the invention, the wire suction device (21) is fixedly disposed in a region of a winding mechanism, and has an upper molded plate (22) and a movably mounted lower molded plate (23), the lower molded plate (23) is arranged to pivot around the roller (34), that is, forming a nozzle contour to which a negative pressure can be applied between the upper molded plate (22) and the lower molded plate (23) so as to pick up the veil on the surface region of the winding spool (5).

The invention relates to a suction nozzle for a workstation of a textile machine which produces crosswound bobbins. The suction nozzle has a suction port for the pneumatic picking of a yarn breakage or a controlled thread cut accumulated on the surface of a cross-wound bobbin end. The suction port is provided with a comb strip for fixing the bobbin end. The comb strip (19) is produced by a photo-chemical etching process and formed with large and small teeth (20, 21) of different heights. The large teeth (20) with a height (H) alternatively appear with the small teeth (21) with a height (h).

The invention discloses a distribution device of an automatic allocating cargo system, and comprises a frame, a pair of rotary conveying chains which are arranged on the frame through chain wheels, and a plurality of wagons which are arranged between the rotary conveying chains. The bottoms of the wagons are provided with switching motherboards which are provided with switching mechanisms, movable splints are arranged below the switching motherboards and four corners of the movable splints are respectively articulated on two pairs of endless chains, the size and the shape of which are respectively, mutually and correspondingly matched with each other. One side of the movable splints is corresponding to the switching mechanisms of the switching motherboards. The invention has the advantages that the goods which are allocated can be unloaded from a plurality of designation places of a conveyor at the lowest drop fall and sent out, taking goods and delivering goods are safe, rapid and reliable, thus the labor intensity of the operators can be reduced.

The invention provides a grabbing device. The grabbing device comprises a grabbing head, a limiting device and an operating rod. The opening track of claws is limited through a limiting ring. An innerrod is pushed or pulled to stretch or retreat so as to open or close the jaws to grab or release objects. By adoption of the grabbing device, the problem that an auxiliary lifting device is needed for aloft work in the prior art, and consequentially, the cost is high, or people cannot work directly by hand on certain occasions is solved. The grabbing device has the advantages of being simple andcompact in structure, convenient to operate and capable of grabbing or picking the objects reliably.
