Referring to Figure 4 (b), the inner fixing rod and the rising separator is installed on the upper side of the separation plate, the lower separator is installed on the outer side of the separation plate. The inner fixing rod, the rising separator, and the falling separator are all composed of a supporting rod (GG) and a head (HD). The head of the inner fixing rod and the rising separator is made of permanent magnets, and the head of the lower separator is made of nonmagnetic material.

The spacer plate 330 is made of a nonmagnetic material. In one embodiment, the spacer plate may have a circular shape.

Magnetic lines of force from the inner anchors and lift separators pass through the separation plates and act on the mesh net. Accordingly, the mesh net is adsorbed on the lower surface of the spaced plate.

The spacing plate also prevents foreign matter from meshing to the head of the inner stator and the head of the lift separator.

The inner holder 340 is installed on the upper side of the separation plate. The inner holder consists of a support rod and a head fixed to the body. The head of the inner holder may be formed of a permanent magnet. In one embodiment, the head of the inner fixing unit may be provided with a shielding film on the side and the upper surface except the lower side in order to generate a magnetic force to the lower side.

Can have

The lift separator 350 is installed above the separation plate. The lift separator consists of a support rod and a head. The support rod and head of the lift separator may rise or descend from the body in response to a signal from the controller. The head of the rising separator may be formed of permanent magnets.

The lifting separator 350 may be formed in plural numbers. The lift separators are radially installed so that a plurality of them have a second radius from the center of the separation plate. Wherein the second radius is greater than the first radius.

As an example, in the case of forming a plurality of rising separators, the number of heads may be adjusted to have a magnetic force capable of absorbing 0.5 to 1.0 times the weight of the average mesh network weight. For example, if there are five rising separators and a magnetic force capable of adsorbing 1.0 times the weight of the average mesh net weight is set, the magnetic force capable of adsorbing 0.2 times the weight of the average mesh net weight on the head of one rising separator. Can have

On the other hand, the sum of the magnetic forces coming from the head of the inner fixing rod and the rising separator may have a magnetic force capable of adsorbing 1.3 to 2.0 times the weight with respect to the average mesh network weight.

According to the present invention, the plurality of rising separators are sequentially raised in accordance with a signal from the controller. The sequential and individual rise of the ascent separator results in a decrease in magnetic force at the bottom of the separation plate.

In one embodiment, the rise of these sequential and individual rise separators continues until the weight of the mesh net detected from the sensor decreases below the reference mesh net weight.

As an example, when the adsorbed mesh network is separated except for one mesh network, the rising separator may be lowered again.

The falling separator 360 is installed on the outside of the separation plate. The descending separator consists of a support and a head. The head of the descending separator is made of nonmagnetic material.

The plurality of descending separators 360 are radially installed at positions having a third radius from the center of the separation plate. Here, the third radius is greater than the second radius.

The lowering separator 360 descends from the upper side of the mounting table to separate the mesh net from the feeder, and seats the mounting area on the mounting table. In one embodiment, the plurality of falling separators are simultaneously lowered according to the signal of the controller. Accordingly, the mesh net can be separated from the spacer plate of the conveyor.

The controller 370 controls the driving of the guide block, the body, the rising separator, and the falling separator. In addition, the controller receives the weight of the mesh network detected from the sensor, and if the weight is equal to or more than the predetermined reference mesh network weight, raises the rising separator.

The reference mesh network weight may be 1.4 to 1.8 times or more weight based on the average mesh network weight. Preferably, the reference mesh network weight may be set to 1.2 to 2.0 times or more with respect to the maximum mesh network weight. The reference mesh net weight may be set in consideration of an error range of the weight of the mesh net.

Hereinafter, the operation of the mesh network transfer apparatus configured as described above will be described. The operation described below is performed by a controller.

Figure 5 shows the operation sequence of the mesh network transfer apparatus according to the present invention, Figure 6 shows a method of transferring the mesh network using the mesh network transfer apparatus according to the present invention.

The conveying method using the mesh network conveying apparatus according to the present invention, by lowering the conveyer to absorb the mesh network loaded on the stacker, and then raising the conveyer (S100), and based on the weight of the mesh network detected from the sensor The step (S200) of determining the driving of the furnace up separator, the step of moving the conveyor to the upper side of the mounting part, and the step (S300) of descending the upper side of the mounting part, and lowering the lowering separator to seat the adsorbed mesh network on the mounting part. It includes the step (S400).

In step S100, the stacker is loaded with a plurality of mesh nets, and the conveyor is lowered on the upper side of the stacker. Subsequently, the feeder adsorbs the mesh net on the uppermost side by the magnetic force of the inner holder and the rising separator of the feeder. Thereafter, the feeder which adsorbs the mesh net is raised to a predetermined height.

In step S200, the controller determines the lift of the lift separator based on the weight of the mesh net detected from the sensor. In this case, the rising separator means a decrease in the magnetic force applied to the mesh network.

One mesh net should be adsorbed to the conveyor, but two or more mesh nets may be adsorbed depending on the loading type of the mesh net. Figure 5 (a) shows that two mesh nets are adsorbed on the separation plate of the conveyor.

When the weight of the mesh net detected from the sensor is equal to or greater than the preset reference mesh net weight, the controller raises one by one among the plurality of lifting separators sequentially. The rise of this rise separator may continue until it is detected at the sensor below the reference mesh net weight. The reference mesh network weight may be set to 1.4 to 1.8 times or more weight of the average mesh network weight.

Referring to FIG. 5 (b), the adsorbed mesh network MSB 2 may be separated, except for one mesh network MSB 1 according to the individual rise of the climbing separator 350. In FIG. 5 (b), reference numeral MSB 1 denotes a mesh net to be transferred, and reference numeral MSB 2 denotes an additionally adsorbed mesh net.

As an example, when the adsorbed mesh network is separated, the rising separator may descend again to increase the magnetic force applied to the mesh network. Accordingly, it is possible to prevent the mesh network falling from the conveyor during the movement of the conveyor.

In step S300, the feeder which has absorbed the mesh net is moved from the upper side of the stacker to the upper side of the mounting table, and descends from the upper side of the mounting table.

In step S400, the mesh network is separated from the conveyor. Referring to FIG. 5C, the plurality of falling separators 360 descends at the same time according to a signal from the controller. As the descending separator descends, the mesh net adsorbed by the magnetic force of the inner fixing member and the rising separator is separated. Thereafter, the separated mesh network is seated in the mounting region of the mounting portion.

Subsequently, the feeder having the mesh net mounted on the mounting part moves back to the stacker to adsorb the mesh net.

According to the present invention, when a plurality of mesh nets are adsorbed by the magnetic force in the conveyor, the magnetic force is reduced by the rise of the sequential and individual rising separators. Accordingly, it is possible to easily separate the mesh mesh further adsorbed, except for one mesh network to be transferred.

As mentioned above, although this invention was demonstrated in detail through the specific Example, this invention is not limited to the said Example, A various deformation | transformation is possible for a person with ordinary knowledge within the scope of the technical idea of this invention.
