2 is a configuration diagram of a raw material automatic weighing system to which a raw material meter according to an embodiment of the present invention is applied, and FIG. 3 is a schematic view of a raw material automatic metering system according to an embodiment of the present invention. Fig. 2 is a top view of a raw material box according to an embodiment of the present invention.

Referring to the drawings, the raw material automatic metering system according to the present invention includes a plurality of raw material meters 110. The number of the raw materials to be discharged may be determined according to the type of the raw material to be discharged or the number of the raw material weighing machines 110 110 may be used.

The raw material metering device 110 includes a hopper 111 for storing raw materials. Different raw materials are stored in the hopper 111 of each raw material meter 110. An opening portion (not shown) is formed in the discharge port of the hopper 111 so that it is normally closed, and when the raw material is discharged, the raw material is discharged. Each of the raw material weighers 110 discharges the raw materials stored in the hopper 111 through the opening and closing part, weighs the raw materials to a predetermined weight, and finally discharges the raw materials to the raw material box 310 located below the raw material weigher 110.

A first discharge plate 112 and a second discharge plate 113 are provided below the hopper 111. The first delivery 112 and the second delivery 113 guide the transfer of the raw materials. The second double-fed publication 113 is installed below the first double-fed publication 112 and the raw material discharged from the hopper 111 is first discharged to the first double-fed publication 112, and then the second double- And is provided to the publication 113. The first and second folding presses 112 and 113 may be installed parallel to the ground or may be inclined, respectively. It is preferable that the inclination angle of the first folding plate 112 is larger than the inclination angle of the second folding plate 113. The reason for the difference in the inclination angles is to provide a large amount of raw material using the first replica 112 and to adjust a minute amount of the raw material using the second replica 113.

A discharge box 114 is provided at the lower part of the second discharge plate 113. The raw material supplied to the second discharge plate 113 is temporarily stored up to a predetermined weight and then supplied to the discharge box 114 at the lower part. The discharge box 114 temporarily stores the raw material after discharging the raw material from the second discharge plate 113. When the predetermined weight is reached, the raw material stored in the raw material box 310 provided below is discharged through the discharge guide unit . To this end, a weight detector 116 is installed on the lower surface of the discharge box 114 to detect the weight of the raw material supplied to the discharge box 114 in real time. The weight detector 116 may be implemented as a load cell, for example. The raw material is supplied from the hopper 111 to the discharge box 114 via the first discharge plate 112 and the second discharge plate 113. At this time, (116). The discharge box 114 is provided with a dump part 121 for discharging the raw material temporarily stored in the discharge box 114 to the lower raw material box 310. The operation of the dump unit 121 causes the discharge box 114 to be inclined by a predetermined angle so that the raw materials stored therein are poured into the raw material box 310 at the bottom.

At this time, in order to quickly and smoothly transfer the raw material discharged from the hopper 111 to the discharge box 114 through the first discharge plate 112 and the second discharge plate 113, Generating units 117 and 118, respectively. These vibration generators 117 and 118 apply vibration to the first backsheet 112 and the second backsheet 113, respectively. For example, the first vibration generating portion 117 and the second vibration generating portion 118 may include vibrators to apply vibrations to the first and second discharge presses 112 and 113, respectively, So that the raw material can be moved and transferred more smoothly by the vibration of the boat presses 112 and 113. More specifically, when the raw material is discharged from the hopper 111 to the first discharge plate 112, the first vibration generating unit 117 operates to vibrate the first discharge plate 112 so that the raw material is discharged to the second discharge plate The second vibration generating portion 118 operates to vibrate the second discharge plate 113 so that the raw material can be smoothly discharged to the discharge box 114 .

A display unit 119 is installed in each raw material meter 110. The display unit 119 displays information including the type of the raw material currently being discharged and the weight of the raw material in the discharge box 114 detected by the weight detecting unit 116 in real time.

The overall operation of the raw material meter 110 is controlled by the control unit 120. The control unit 120 controls the operation of the opening and closing unit (not shown) of the hopper 111, the first and second vibration generating units 117 and 118, the display unit 119 and the dump unit 121, Lt; RTI ID = 0.0 > 210 < / RTI >

As shown in the figure, each raw material weigher 110 is preferably arranged in a row, and different raw materials are stored in the hopper 111 of each raw material weigher 110. Each of these raw materials is mixed later to become a material for a specific product such as a shoe, a bag, or a wallet. A moving carriage 210 on which a plurality of raw material boxes 210 are mounted is disposed under each of the raw material meters 110. These moving carts 210 can be moved forward and backward along the respective raw material meters 110 arranged in a line by the control unit 120. Apart from this, the plurality of raw material containers 210 can be moved leftward or rightward . Here, the raw material box 310 rotates on the basis of a virtual center point of the plurality of circular boxes 210, not the individual raw material box 210 itself. Accordingly, by this rotation, the first raw material box moves to the position of the second raw material box and the second raw material box moves to the position of the third raw material box so that each raw material box 310 moves to the position of the neighboring raw material box 310 To move one space at a time. The discharge port of the specific raw material meter 110 is rotated by the control unit 120 of the plurality of raw material containers 210 so that the position of the raw material box 210 corresponds to the discharge port of the raw material meter 110, Box 210 as shown in FIG. To this end, the moving carriage 210 is provided with a first driving part 211 for performing the forward movement and the backward movement of the moving carriage 210 and a second driving part 211 for performing the rotation in the leftward direction and the rightward direction of the raw material box 310, A driving unit 212 is provided. The operation of the first driving unit 211 and the second driving units 211 and 212 is controlled by the control unit 120. The operation of the first and second driving units 211 and 212 correspond to different raw material containers 210 for each raw material weighing device 110 so that different raw materials for each raw material supplying device 110 are discharged to different raw material containers 210 .

In yet another embodiment of the present invention, the raw material automatic metering system may further include a bar code label output unit, although not shown in the drawing. The bar code barrel output unit (not shown) outputs a bar code label containing information on each raw material when the raw material is accurately discharged to the raw material box by a predetermined weight for each raw material weighing device 110. For this purpose, the control unit 120 stores a predetermined target weight for each raw material weigher 110. When the weight of each raw material stored in the discharge box 114 reaches a predetermined target weight at the weight detecting unit 116 The raw material stored in the discharge box 114 is completely discharged to the lower raw material box 310 and then the barcode label output unit is operated to output a barcode label containing information for each raw material for each raw material meter 110. The information contained in such a bar code label may include weight, raw material name, kind, ingredient, etc. for each raw material. In another example, when all of the raw materials are completely discharged to the raw material box 310 by all of the raw material meters 110, the control unit 120 operates the barcode label output unit to generate a barcode label containing information on each raw material Output. At this time, barcode label is not output when abnormal weighing is performed. Such a barcode level is to be attached to each raw material so that the operator can identify the raw material later.

 The operation of the raw material automatic weighing system of the present invention thus configured will be described.

The control unit 120 opens the opening and closing unit provided at the lower part of the hopper 111 so that the raw material stored in the hopper 111 is discharged to the outside of the hopper 111 And discharged to the first discharge plate 112 installed at the lower portion of the discharge port. At this time, the control unit 120 operates the first vibration generating unit 117 to cause the first discharge plate 112 to vibrate, so that the material can be discharged from the first discharge plate 112 more quickly and smoothly 113). When the raw material is supplied from the first feeder 112 to the second feeder 113, the controller 120 operates the second vibration generator 118 to apply vibration to the second feeder 113 So that the raw material is discharged to the lower discharge box 114 more quickly and smoothly in the second discharge plate 113.

When the raw material starts to be discharged to the discharge box 114, the weight detector 116 installed on the lower surface of the discharge box 114 detects the weight of the raw material stored in the discharge box 114 in real time. The weight detected in real time is transmitted to the control unit 120, and the control unit 120 displays the weight through the display unit 119. Therefore, the weight of the raw material in the discharge box 114 is displayed on the display unit 119 in real time.

At this time, the control unit 120 may control the operation of the first and second vibration generators 117 and 118 according to the weight of the raw material discharged to the discharge box 114. [ For example, the control unit 120 controls the first vibration generating unit 117 and the second vibration generating unit 117 until the predetermined weight of the target weight of the raw material to be discharged is detected, in real time, by the weight detecting unit 116 and transmitted to the controller 120 in real time. The second vibration generating unit 118 is operated simultaneously and the first vibration generating unit 117 is stopped until the predetermined target weight is reached after the second vibration generating unit 118 is operated, It is also possible to make them sequentially adjustable. Alternatively, the control unit 120 may operate the first vibration generating unit 117 and the second vibration generating unit 118 to a predetermined weight among the target weight of the raw material to be discharged, The first vibration generating unit 117 and the second vibration generating unit 118 are operated at a frequency smaller than the preset frequency until the weight is reached and the weight change from the preset weight to the target weight can be gradually adjusted in small steps . For example, the first vibration generating unit 117 and the second vibration generating unit 118 may be operated simultaneously to 95% of the target predetermined weight so that the raw material is supplied to the first discharge plate 112 and the second discharge plate 113, The operation of the first vibration generating portion 117 is stopped and only the second vibration generating portion 118 is operated after 95% so that only the second backing plate 113 So that a small amount of raw material is supplied to the discharge box 114 so that the weight can be finely adjusted or the first and second vibration generating units 117 and 118 can be operated at a relatively fast first frequency up to 95% %, It is possible to operate at a relatively slow second frequency. Of course, the above values are only exemplary and can be changed.

The control unit 120 closes the opening and closing part of the hopper 111 when the weight reaches a predetermined weight for each raw material meter 110, that is, for each raw material, and at the same time, the first vibration generating unit 117, The operation of the second vibration generating unit 118 is stopped and the dump unit 121 is operated to completely discharge the raw material stored in the discharge box 114 into the lower raw material box 310. [ Thus, the raw material of the target weight is supplied to the raw material box 310. In the present invention, the control unit 120 sequentially controls the weighing of the raw material for each raw material weighing device 110.

For example, six raw material meters 110a to 110f and six raw material boxes 310a to 310f are shown in the drawing, and a control method of the raw material automatic metering system according to the present invention will be described below with reference to the drawings. The number of raw material meters and raw material boxes can be changed as well. Further, in another embodiment, only a selected one of the six raw material meters 110a to 110f may be used, so that a part of the raw material box can be used.

The control unit 120 controls the first driving unit 211 to move the moving carriage 210 to the lower portion of the first raw material meter 110a so that the raw material is weighed to a predetermined target weight at the first raw material meter 110a . At this time, the first raw material box 310a is positioned below the first raw material meter 110a. The control unit 120 operates the dump unit 121 of the first raw material accumulator 110a so that the raw material of the target weight stored in the discharge box 114 is supplied to the first raw material meter 110a, And is discharged to the raw material box 310a.

The control unit 120 controls the second raw material weigher 110b to measure the raw material to a predetermined target weight and operates the first driving unit 211 to move the moving car 210 to the second raw material meter 110b. As shown in FIG. At this time, the control unit 120 operates the second driving unit 212 of the moving bogie 210 to rotate the six raw material boxes 210 and the second raw material box 310b rotates the lower portion of the second raw material meter 110b . Of course, the control unit 120 may selectively rotate the raw material box 210 during the movement of the moving car 210, rotate the raw material box 210 first and move the moving car 210 to the second raw material meter 110b. When the moving truck 210 is positioned below the second raw material weigher 110b and the second raw material box 310b corresponds to the outlet of the second raw material weigher 110b, The control unit 120 operates the dump unit 121 of the second raw material accumulator 110b to discharge the raw material stored in the discharge box 114 to the second raw material box 310b.

As described above, this process is similarly applied to the last sixth raw material meter 110f. That is, when the target weighing of the raw material is completed in one raw material weigher 110, the weighed raw material is discharged to the corresponding raw material box 310 and then the moving car 210 is moved to the next raw weigher 110 The raw material box 310 is rotated to discharge the other raw material to the next raw material box 310. By applying the same process to the raw material raw material meter 110 in the same way, 110 are supplied from different sources. Here, the control unit 120 operates the dump unit 121 in the last sixth raw material meter 110f to move the moving carriage 210 to the original initial position when the discharge of the raw materials metered to the final raw material box 310f is completed . This is for re-discharging the raw material from the beginning through the same process as described above. At this time, in the embodiment of the present invention, the control unit 120 waits for a preset time from the time when the dump unit 121 of the last raw material meter 110 is operated, and moves the moving bobbin 210 to the initial position . This is to take into account the time for the dump part 121 to operate and completely discharge the raw material into the raw material box 310.

As described above, in the raw material automatic metering system and its control method according to the present invention, different raw materials are stored in each hopper of a plurality of raw material meters, and the weight of the raw materials is measured for each raw material, and then discharged to the raw material box at the bottom . In the present invention, in the present invention, the raw material is measured at a target weight in each raw material gauges, a moving car loaded with a raw material box at the bottom of each raw material gauger is moved to a position corresponding to the discharge port of each raw material gauges, Allow different raw materials to be discharged in the raw material box. Particularly, the control unit 120 controls the weighing of the raw material to the target weight, discharge of the raw material, movement of the moving bogie, rotation of the raw material box in each raw material weighing machine, .
