Abstract: The present invention relates to a vacuum ejector pump including a plurality of nozzles, which are assembled, and activated by compressed air passing through the nozzles at a high speed to generate a negative pressure in an outer surrounding space. The pump of the present invention includes an intermediate nozzle, a first nozzle on which a front-cover part inserted to an outer circumference of one end of the intermediate nozzle is formed, and a second nozzle on which a rear-cover part inserted to an outer circumference of the other end of the intermediate nozzle is formed. Here, the intermediate nozzle is disposed between the first nozzle and the second nozzle, and the intermediate nozzle, the first nozzle and the second nozzle constitute an ejector main body. The surrounding space communicates with each of the nozzles through a through-hole defined in a sidewall of the ejector main body and a slot defined between the nozzles.

Abstract: The present invention discloses a gripper device using an air-tube. Particularly, the gripper device quickly performs ‘release’ on gripping of a product. The gripper device is designed so that compressed air for griping, which is introduced through a first tube and accumulated in an expansion space of a side wall of the cylindrical air-tube, is instantly discharged to the outside through a second tube that is opened by a reverse movement of a valve and the air-tube. Thus, the ‘release’ is quickly performed to resultantly extremely reduce an operation time of a transfer operation in which gripping, transferring, releasing, and returning of the product are repeated.

Abstract: The present invention relates to a vacuum suction pad applied to a vacuum transfer system. The vacuum suction pad has a structure in which a plurality of suction cells are formed by flexible partition walls. The vacuum suction pad includes a coil spring that is coaxially installed at a central portion in a longitudinal direction in each of the suction cells and spaced a distance from the partition wall and a pipeline flow control valve coupled to a lower end of the spring. The suction pad is coupled with a separately provided body to constitute a vacuum gripper of the present invention, and the gripper is connected to a vacuum pump through an exhaust port defined at one side of the body.

Abstract: The present invention relates to an air-valve unit for a vacuum system. The valve unit may include a control part, which detects a pressure of an external exhaust space to output an on/off signal, to actively control supply/blocking of air into/from an exhaust hole. Also, the valve unit is preferably constituted by a plurality of holes and electronic valves so that an opening/closing of an outlet of each of the holes is controlled by the control part, and thus, extension of a vacuum generation line or combination of generation/destruction lines may be implemented.

Abstract: The present invention relates to a vacuum multi-sensing unit (10) used for adhesion and transfer of an object (P) together with a vacuum pump (23) in a vacuum transfer system. The multi-sensing unit (10) of the present invention includes a plurality of sensors (13) to perform multi-sensing, wherein individual and collective control of the built-in sensors (13) is possible. Therefore, in particular, when a plurality of vacuum pumps (23) are required for transfer of objects (P), the plurality of vacuum pumps (23) are allowed to correspond to a single unit (10), and thus, compared to a conventional sensing unit individually attached to each vacuum pump, there is superior effect in terms of the efficiency of manufacture, installation, management, operation, and control of the unit (10).

Abstract: The present invention relates to a vacuum pump using a profile. The vacuum pump according to the present invention comprises: a hollow profile having a longitudinal mounting hole and a vacuum chamber formed adjacent to each other; an ejector pump arranged inside the mounting hole in the longitudinal direction; and end caps provided in both openings of the profile, respectively, so as to have a through-hole formed therein so as to correspond to the inflow opening or the discharge opening. Particularly, the first cap near the inflow opening is designed to have a passage through which the vacuum chamber and the mounting hole communicate with each other. The vacuum pump structure according to the present invention is considered to be a vacuum pump structure using at least a so-called “profile” best designed to make fabrication of the vacuum pump convenient and to improve vacuum characteristics.
