For example, when the weighing hopper 120 is configured in a rectangular box shape, the load cell 123 may be provided at four corners of the weighing hopper 120, but the present invention is not limited thereto.

The weight error of the raw material can be minimized through the plurality of load cells 123 provided symmetrically to the weighing hopper 120.

For example, when the raw materials are stored in one side of the weighing hopper 120 in a biased manner and the measured values of the plurality of load cells 123 are different, an average of the different measured values can be determined as a basis weight of the raw material. But is not limited thereto.

When the load cell 123 is used for a long period of time, the balance between the plurality of load cells 123 may not be balanced, resulting in a difference in the measured values of the plurality of load cells 123. At this time, the user can arrange the mass body M on the mass body mounting part 124 to balance the plurality of load cells 123.

In addition, in one embodiment, the weighing hopper 120 may be provided with a tensioning device 126 for balancing the weighing hopper 120.

The tension device 126 is configured to adjust the inclination of the weighing hopper 120 to balance the weighing hopper 120. In addition, the tension device 126 can prevent the weighing hopper 120 from being shaken and eccentric during the weighing process.

Further, in one embodiment, the weighing hopper 120 may include a vibrating feeder 128 for conveying the raw material to a conveyor 130, described below, at the outlet at the bottom.

In one embodiment, the vibrating feeder 128 may be coupled to the weighing hopper 120 and may oscillate the raw material so that the raw material discharged from the weighing hopper 120 may be supplied to the conveyor 130 smoothly without aggregation Can be transported.

Further, in one embodiment, the opening end of the vibrating feeder 128 may be provided with an opening / closing door 129.

When the weighing hopper 120 is weighed by the weighing hopper 120 and the weighed raw material is conveyed to a conveyor 130 to be described later, a small amount of raw material is conveyed from the vibrating feeder 128 to the conveyor 130, It is possible to perform a function of shielding the discharge end of the vibrating feeder 128 so as not to flow out.

The conveyor 130 receives the raw materials from the plurality of weighing hoppers 120 and can transfer the supplied raw materials to the input chute 160 to be described later.

To this end, the conveyor 130 may be provided below a plurality of weighing hoppers 120 arranged in a row as shown in FIG.

The conveyor 130 is movable when the raw materials are supplied from the entire plurality of weighing hoppers 120, and can transfer the raw materials stacked on the top.

Thus, each of the plurality of weighing hoppers 120 loads the raw material at different positions on the conveyor 130.

In one embodiment, the conveyor 130 may be configured to be capable of forward and reverse transport in accordance with a control signal.

The tension adjuster 140 can adjust the tension of the conveyor 130.

5, the tension adjuster 140 may be disposed at both ends of the rotation axis of the pulley 132 so as to adjust the horizontal position of the pulley 132 rotating the conveyor 130 But the present invention is not limited thereto.

The tension adjuster 140 adjusts the tension of the conveyor 130 according to the weight of the material to be loaded on the conveyor 130 and the feed rate of the material to thereby generate a strong load on the conveyor 130 The service life of the conveyor 130 can be improved.

The dust cover 150 is a structure that surrounds the loading area of the conveyor 130 so that the dust of the raw material conveyed through the conveyor 130 is not scattered or diffused into the factory.

In one embodiment, the vibrating feeder 128 may be arranged to penetrate a portion of the dust cover 150 as shown in FIG. 2 to load the raw material on the conveyor 130.

Although not shown, in one embodiment, a transparent window (not shown) may be formed on at least a portion of the dust cover 150 to visually check the operation status of the conveyor 130 and the conveying condition of the raw material from the outside .

The air-rich portion 152 is provided in the dust cover 150 and is provided to flow the dust inside the dust cover 150 to an external dust collection facility (not shown).

In one embodiment, a plurality of air blowing portions 152 may be provided at the upper end of the dust cover 150, and the number, shape, and mechanical configuration are not particularly limited.

The weighing hopper 160 is provided to feed a weighed raw material to a weaving and decarburizing process facility following the weighing and weighing process performed by the feeder 100 according to an embodiment of the present invention.

The feed chute 160 may be disposed at an end of the conveyor 130 to receive the raw material conveyed from the conveyor 130 and chute the raw material to a decarburization facility (not shown).

In one embodiment, the input chute 160 may be provided at both ends of the conveyor 130. At this time, the conveyor 130 can transfer the raw materials alternately to each of the input chutes 160 provided at both ends through forward feed and reverse feed, as described above.

The vibration generating unit 170 may generate vibrations in the input chute 160 so that the raw material can be smoothly chucked by separating the raw material introduced into the input chute 160 from the conveyor 130.

For this, for example, the vibration generating unit 170 may include a cylinder member 174 (see FIG. 4A) and a reciprocatingly movable piston rod 172 coupled to one side of the input chute 160 ).

Here, the piston rod 172 reciprocates to generate vibration in the input chute 160.

In the weighing and conveying apparatus 100 according to an embodiment of the present invention as described above, the load cell 123 is fixed so that the failure occurrence rate of the load cell 123 is reduced and the weighed error is reduced.

In addition, the weighing and conveying apparatus 100 according to an embodiment of the present invention has an advantage that the feed rate of the raw material can be improved because the raw material can be continuously conveyed through the conveyor 130.

In addition, since the weighing and conveying apparatus 100 according to the embodiment of the present invention is loaded with various kinds of raw materials at different positions of the conveyor 130 and then put into the input chute 160 in order, Thereby preventing the clogging of the input chute 160 due to the clogging.
