The foregoing and other objects, features and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention and the manner of achieving them will become apparent with reference to the embodiments described in detail below with reference to the accompanying drawings. Like reference numerals refer to like elements throughout the specification.

FIG. 1 is a plan view of an adsorption transfer apparatus using a magnetic force and vacuum according to an embodiment of the present invention, FIG. 2 is a side sectional view showing a schematic structure of the adsorption transfer apparatus shown in FIG. 1, Fig.

Hereinafter, an adsorption transfer apparatus using a magnetic force and vacuum according to an embodiment of the present invention will be described with reference to the drawings.

Referring to FIG. 1, a suction conveying apparatus using a magnetic force and a vacuum according to an embodiment of the present invention includes a conveyor belt 100 for conveying a conveying object, a driving unit 110 for driving the conveyor belt 100, And a profile 200 installed inside the conveyor belt 100 for attracting the conveyed object to the outer surface of the conveyor belt 100 by a magnetic force and a vacuum.

First, the conveyor belt 100 is formed to have a predetermined width so as to be able to carry and transport the object to be conveyed, and is circularly rotated by the driving unit 110.

The driving unit 110 includes driving pulleys (not shown) installed at both ends of the conveyor belt 100 and wound by the conveyor belt 100, and driving pulleys And a driving motor (not shown) for supplying a driving force.

The object to be conveyed is a magnetic material such as iron (Fe), nickel (Ni), cobalt (Co) and alloys thereof, and a viscous material such as aluminum (Al), copper (Cu), tin Lt; / RTI > material.

Next, the profile 200 is used to attract the conveyed object to the outer surface of the conveyor belt 100 by a magnetic force and a vacuum, and is installed inside the conveyor belt 100.

At this time, the profile 200 installed inside the conveyor belt 100 may have an integral or separate profile structure. For example, the integral profile structure may be in the form of a profile having a length corresponding to the inner length of the conveyor belt 100, and the separable profile structure may include a plurality of profile units having a predetermined length, And may be assembled so as to correspond to the length.

The profile 200 may include a first recessed portion 210 and a second recessed portion 220 which are communicated with an inner surface of the conveyor belt 100 and may be recessed at a predetermined depth along the longitudinal direction.

2, the first recessed portion 210 includes an electromagnet (not shown) formed at a lower central portion of the profile 200 to generate the magnetic force, A vacuum nozzle 320 formed at both sides of the lower end of the profile 200 and connected to an external vacuum generator (not shown) may be installed.

At this time, on the outer surface of the conveyor belt 100, a plurality of vacuums communicating with the second recessed portion 220 so that a vacuum generated in the second recessed portion 220 can pass through the outer surface of the conveyor belt 100 The adsorption holes 230 may be formed at intervals.

For example, by operating an external vacuum generator (not shown) connected to the vacuum nozzle 320, air in the second recessed portion 220 is sucked to adjust the internal pressure of the second recessed portion 220 to be lower than the atmosphere The ambient air of the vacuum adsorption hole 230 communicated with the second recess groove 220 is continuously introduced into the second recess groove 220 through the vacuum adsorption hole 230, The inner space of the two recessed grooves 220 is maintained in a vacuum state lower than the outer pressure, so that a suction force of a predetermined magnitude acts to attract and fix the object to be conveyed.

Accordingly, the magnetic material is attracted to the outer surface of the conveyor belt 100 by the magnetic force of the electromagnet (not shown), and the non-magnetic material is adsorbed by the vacuum section formed in the second recessed portion 220 And is conveyed along the moving direction of the conveyor belt 100.

The second recessed portion 220 may be provided with a partition wall 224 partitioning the internal space in the longitudinal direction into a vacuum space and a non-vacuum space depending on the position of the vacuum nozzle 320 .

3, at least one partition wall 224 is provided in the inner space of the second recessed groove 220 formed horizontally along the longitudinal direction of the profile 200, It can be divided into two or more spaces based on the partition wall 224.

For example, when the air in the predetermined space S partitioned by the partitioning partition wall 224 is exhausted by the operation of a vacuum generator (not shown) connected to the vacuum nozzle 320 and the internal pressure is lowered, Ambient air of the vacuum adsorption holes 230 formed at the positions corresponding to the predetermined spaces S continuously flows into the predetermined space S while the vacuum generator is operated through the vacuum adsorption holes 230 As the vacuum state is maintained in the predetermined space S, the conveyance object is attracted and fixed by the attraction force acting through the vacuum adsorption hole 230. Thereafter, when the conveyed object is conveyed to the stacking position by the conveyor belt 100 and the operation of the vacuum generator is stopped, the predetermined space S becomes equal to the external pressure and the attraction force is no longer generated, The object is separated from the outer surface of the conveyor belt 100 and falls.

At this time, it is preferable to provide the partition ribs 224 so that at least one vacuum nozzle 320 is included in each space.

In this case, by controlling the operation of the vacuum generator (not shown) connected to the vacuum nozzle 320 provided at the position corresponding to each space, the operator can control the divided spaces to be a vacuum space or a non-vacuum space , It is possible to divide the vacuum section in the profile 200 so as to correspond to the drop position of the object to be conveyed, thereby improving convenience and work efficiency of the operator.

Meanwhile, according to the present invention, it is also possible to control the section in which the magnetic force is generated by adjusting the number and position of the electromagnets (not shown) accommodated in the first yaw groove portion 210.

Here, the lower surface of the profile 200 may be provided with a plurality of bearings 500 for reducing friction with the inner surface of the conveyor belt 100.

For example, as shown in FIGS. 1 and 2, when a plurality of bearings 500 protrude from the lower surface of the profile 200 and are installed to contact the inner surface of the conveyor belt 100, 100, it is possible to reduce the conveying force due to the friction generated in the profile 200, so that the conveying speed of the conveying object by the conveyor belt 100 can be increased.

The suction conveying apparatus using the magnetic force and the vacuum according to the embodiment of the present invention includes a conveyor belt 100 and a support 200 for preventing deflection of the conveyor belt 100 due to its own weight at both ends of the profile 200. [ And may further include a bracket 400.

For example, as shown in FIG. 2, the support bracket 400 may be provided to cover both sides of the lower surface of the conveyor belt 100 and the upper and side ends of the portion protruding to both sides of the profile 200, respectively. Quot; or "C" -shaped cross-section.

In this case, it is possible to prevent the conveyor belt 100 from sagging due to its own weight, to maintain the attracting force according to the magnetic force and vacuum generated in the profile, and to stably move the conveyed object.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
