  FIG. 2 is a schematic perspective view showing an example of a bar-shaped member 600 distributed in the bar-shaped member sorting apparatus 100 of FIG.

As shown in FIG. 2, the bar-shaped member 600 includes five bar-shaped members 601. In the present embodiment, the case corresponding to the measured value of the five rod-shaped members 601 will be described as the rod-shaped member 600. Therefore, the bar-shaped member 600 in the present embodiment is an article having a measurement value that is five times the measurement value of the bar-shaped member 601.
In the present embodiment, the rod-shaped member 600 is composed of a rod-shaped member having a measured value corresponding to the five rod-shaped members 601, but is not limited to this, and a count value is used instead of the measured value. In addition, the number may be any other number instead of five, and the article is not limited to a rod-shaped member, and may be an article of any other shape such as a square rod member, a circular member, or the like. .

  Subsequently, an example of a process of distributing the bar-shaped member 600 in each apparatus of the bar-shaped member distributing apparatus 100 will be described in detail with reference to FIGS. 3 is a schematic step view showing steps in the dispersion feeder apparatus 200, FIG. 4 is a schematic sectional view showing steps in the combination weighing apparatus 300, and FIG. 5 is a schematic view showing steps in the rotary sorting apparatus 400. FIG. 6 is a schematic cross-sectional view showing a process in the discharge device 500.

  First, as shown in FIG. 3, in the distributed feeder device 200 of the rod-shaped member sorting device 100, the rod-shaped member 601 is put into the conical member of the stacking unit 205. The rod-shaped members 601 are collected in the center by the stacking unit 205 and then sent to the transport feeder unit 206 provided downstream. The rod-like member 601 is vibrated and dispersed in the horizontal direction by the action of the magnet and coil of the transport feeder unit 206, and is uniformly charged into the pool hopper 211,. The pool hoppers 211,..., And the gates 221..., And gates 227 built in the pool hopper 217 rotate at predetermined time intervals, so that the rod-shaped members 601 in the pool hoppers 211,. The combination weighing device 300 is dropped.

  Subsequently, as shown in FIG. 4, in the combination weighing device 300 of the rod-shaped member sorting device 100, the rod-shaped member 601 dropped from the dispersion feeder device 200 is thrown into the weighing units 311 to 317. In the present embodiment, the rod-like member 601 thrown from the pool hopper 211 is thrown into the weighing unit 311, and the rod-like member 601 thrown from the pool hopper 212 is thrown into the weighing unit 312 and thrown from the pool hopper 213. The rod-shaped member 601 is loaded into the weighing unit 313, the rod-shaped member 601 loaded from the pool hopper 214 is loaded into the weighing unit 314, and the rod-shaped member 601 loaded from the pool hopper 215 is loaded into the weighing unit 315. Then, the rod-like member 601 thrown from the pool hopper 216 is thrown into the weighing unit 316, and the rod-like member 601 thrown from the pool hopper 217 is thrown into the weighing unit 317.

  Next, the measured value of the rod-shaped member 601 input in each of the measuring units 311 to 317 is calculated. Then, those measurement results are given to a built-in computer (not shown).

  In addition, the weighing units 311 to 317 open the lower ends of the weighing units 311 to 317 when the weighing is finished. Thereby, the rod-shaped member 601 that has been weighed is put into the hoppers 321 to 327 arranged vertically below.

  On the other hand, the computer selects a combination of a plurality of hoppers out of the hoppers 321 to 327 so that the prescribed measurement value, that is, the measurement value of the rod-shaped member 600 in this embodiment, is selected. The lower end of the hopper is opened at a predetermined timing.

  For example, as shown in FIG. 4, by opening the lower ends of the hopper 322 and the hopper 326, the bar-shaped member 601 is dropped onto the collective conveyors 350 and 351. In this case, three bar-shaped members 601 and two bar-shaped members 601 are assembled by the collective conveyors 350 and 351, and five bar-shaped members 601, that is, the bar-shaped members 600 are put into the hopper 380. In this case, the opening / closing mechanism 370 pushes out the cylinder 371 and closes the lower end portion of the hopper 380.

  4 is provided so that the bar-shaped member 601 does not move from the collective conveyor 350 to the collective conveyor 351 or from the collective conveyor 351 to the collective conveyor 350. Further, the bar-shaped member 600 is arranged in one direction by the arranging member 360. Specifically, the bar-shaped member 600 is arranged so as to extend from the near side to the far side with respect to the paper surface of FIG.

  Subsequently, the hopper 380 holds the rod-shaped member 600 dropped from the collective conveyors 350 and 351 for a predetermined time. The opening / closing mechanism 370 pulls out the cylinder 371 from the opening / closing mechanism 370 and opens the lower end portion of the hopper 380 at predetermined time intervals. As a result, the rod-shaped member 600 is dropped onto the rotary sorting device 400.

  In this embodiment, one hopper 380 is provided. However, the present invention is not limited to this, and any other number of hoppers 380 may be provided continuously in the vertical direction.

  Subsequently, the charged rod-shaped member 600 is held by the holding member 410 of the rotary sorting apparatus 400 of FIG. Here, the details of the structure of the holding member 410 will be described with reference to the drawings.

  FIG. 7 is a schematic process diagram for explaining a state in which the rod-shaped member 600 is held by the rotary distribution device 400. FIGS. 7A, 7B, and 7C sequentially show the process from upstream to downstream.

  As shown in FIG. 7A, both end portions of the rod-shaped member 600 are held by a holding member 410 made of a pair of U-shaped members. Next, the endless belt 450 of FIG. 5 is moved by the pair of drive units 420, and the holding member 410 is moved. In this case, as shown in FIG. 7B, before the holding member 410 starts to reverse, the guide member 440 is interposed between the holding member 410 made of a pair of U-shaped members and a pair of U-shaped members. It functions to suppress the opening side of the holding member 410 made of. As shown in FIG. 5, the guide member 440 is provided at a constant interval from the endless belt 450.

  Next, as shown in FIG. 7C, the opening of the holding member 410 made of a pair of U-shaped members is reversed so as to face vertically downward. In this case, the guide member 440 prevents the rod-shaped member 600 from falling. Further, when the holding member 410 is moved up to the predetermined discharge hoppers 511 to 515, the shutter 460 moves so as to open the opening of the holding member 410 made of a pair of U-shaped members. For example, as illustrated in FIG. 7C, the shutter 460 performs an axis rotation operation in the direction of the arrow S1. As a result, the rod-shaped member 600 held by the holding member 410 is dropped downward and is put into a specific discharge hopper among the discharge hoppers 511 to 515.

  As described above, in the rotary distribution device 400, the process is continuously performed. For example, one holding member 410 and the other holding member 410 shown in FIG. 5 are continuously fixed to the endless belt 450, and the rod-like member 600 held by one holding member 410 is put into the discharge hopper 511. Then, the bar-shaped member 600 held by the other holding member 410 is put into the discharge hopper 512. Thus, in the rod-shaped member sorting apparatus 100 according to the present invention, the rod-shaped members 600 can be sorted continuously.

  Moreover, as shown in FIG. 6, the discharge device 500 gives the bar-shaped member 600 thrown into the discharge hoppers 511 to 515 to the packaging device provided downstream. As a result, the rod-shaped member 600 can be continuously packaged. In other words, even when the number of manufactured bar-shaped members 600 is increased, the bar-shaped members 600 are continuously fed from the rotary sorting device 400. Therefore, by further increasing the number of the discharge hoppers 511 to. Can be easily realized.

  In the present embodiment, the holding member 410 is a pair of U-shaped holding members. However, the holding member 410 is not limited to this, and is a holding member having any other shape that can hold the rod-shaped member 600. Also good. In this embodiment, the guide member 440 is continuously provided. However, the present invention is not limited to this, and any structure may be used as long as the rod-shaped member 600 that is an article does not fall. Furthermore, in FIG. 5, although the case where the endless belt 450 was used was demonstrated, it is not limited to this, Arbitrary conveyance structures, such as only a chain structure, may be sufficient. In addition, although the pair of driving units 420 are fixed, the present invention is not limited to this, and at least one of the driving units may be movably provided. That is, the drive part 420 moves and the few holding members 410 are moved on many discharge hoppers. Thereby, the rod-shaped member 600 can be distributed to a large number of discharge hoppers with a small number of holding members 410, and at the same time, the height in the vertical direction can be suppressed.

(Other examples)
FIG. 8 is a schematic process diagram for explaining a state of another example in which the rod-shaped member 600 is held by the rotary sorting device 400 shown in FIG. 8A, 8B, and 8C sequentially show the process from the upstream to the downstream.

As shown in FIG. 8A, the holding member 410a of the rotary sorting apparatus 400 is made of one U-shaped member instead of the holding member 410 made of a pair of U-shaped members shown in FIG. As shown in FIG. 8B, the guide member 440a is composed of a pair of plate-like members instead of the guide member 440 shown in FIG.
As shown in FIG. 8A, the central portion of the rod-shaped member 600 is held by a holding member 410a made of a U-shaped member. Next, the endless belt 450 is moved by the pair of drive units 420, and the holding member 410a is moved. In this case, as shown in FIG. 8 (b), before the holding member 410a starts to reverse, the guide member 440a is held at both ends of the holding member 410a made of a U-shaped member and is made of a U-shaped member. It serves to suppress the opening side of 410a. The guide member 440a is provided at a constant interval from the endless belt 450.

  Next, as shown in FIG. 8C, the holding member 410a made of a U-shaped member is inverted so that the opening is directed vertically downward. In this case, the rod member 600 is prevented from dropping by the guide member 440a. Further, when the holding member 410a is moved up to predetermined discharge hoppers 511 to 515, the shutter 460a moves so as to open the opening of the holding member 410a made of a U-shaped member. For example, as shown in FIG. 8C, the shutter 460a moves horizontally in the direction of the arrow S2. As a result, the rod-like member 600 held by the holding member 410 a is dropped downward and is put into a specific discharge hopper among the discharge hoppers 511 to 515.

  9 to 14 are schematic explanatory views for explaining the effect of the rod-shaped member sorting apparatus 100 according to the present invention.

  First, as shown in FIG. 9, the vertical height of the rotary sorting device 400 in the rod-shaped member sorting device 100 according to the present embodiment is a height H1. The height H1 depends only on the heights of the plurality of holding members 410 and the height of the pair of drive units 420 in the rotary sorting apparatus 400. FIG. 10 shows a case where the number of discharge hoppers is increased as compared with the discharge device 500 of FIG. In the case of the rotary sorting device 400z and the discharge device 500z shown in FIG. 10, the size of the device itself can be reduced by using the rotary sorting device 400z provided with a larger number of holding members 410 instead of the rotary sorting device 400. The height H1 can be prevented from increasing only by extending in the horizontal direction.

  On the other hand, as shown in FIG. 11, in the sorting device 800 and the discharging device 500 provided with hoppers in a staircase shape, the height in the vertical direction of the sorting device 800 is a height H2. In this sorting apparatus 800, as indicated by an arrow, articles are sorted from one upstream hopper to two adjacent hoppers downstream. Further, the height H2 depends on the number of hopper stages in the sorting apparatus 800. FIG. 12 shows a case where the number of discharge hoppers is increased as compared with the discharge device of FIG. In the case of the sorting device 800z and the discharging device 500z shown in FIG. 12, the number of hopper stages is increased, so that the height H2 becomes the height H21 (H2 <H21).

Further, as shown in FIG. 13, in the sorting device 810 and the discharging device 500 provided with the discharge chute, the vertical height of the sorting device 810 is a height H3. In the sorting device 800, the slide device 815 projects or pulls the shaft, so that the discharge chute is swung in the direction of the arrow. The height H3 depends on the length of the discharge chute in the sorting device 810.
FIG. 14 shows a case where the number of discharge hoppers is increased as compared with the discharge device 500 of FIG. In the case of the sorting device 810z and the discharge device 500z shown in FIG. 14, the length of the discharge chute becomes long, and thus the height H3 becomes the height H31 (H3 <H31).

  As described above, in the rod-shaped member sorting apparatus 100 according to the present invention, since the endless belt 450 is moved in a substantially circular shape, a plurality of hoppers are provided stepwise as shown in FIGS. 11 and 12. In the case, or even when the transport quantity of the rod-shaped member 600 is increased and the discharge hoppers 511 to 515 are increased as compared with the case where the distribution chute member is provided as shown in FIGS. 13 and 14, An increase in the height H1 of the rotary distribution device 400 can be suppressed. That is, a large number of rod-shaped members 600 can be continuously distributed to a large number of discharge hoppers with a substantially circular diameter size to which the endless belt 450 moves. Therefore, since the height H1 of the rotary sorting device 400 can be kept low, it is possible to prevent damage or damage to the rod-shaped member 600 sorted by the rotary sorting device 400. Furthermore, even when the number of discharge hoppers is increased, the height H1 of the rotary sorting device 400 can be kept low by extending the endless belt 450 in the horizontal direction. Furthermore, compared with the apparatus of FIGS. 11-14, the number of parts which comprise the rotation distribution apparatus 400 can be decreased, and the increase in the response time of a trouble occurrence or a maintenance, for example, daily cleaning can be suppressed. .

  Furthermore, in the rod-shaped member sorting apparatus 100 according to the present invention, the weighing units 311 to 317 are composed of the combination weighing device 300, so that a large number of rod-shaped members 600 are arranged at high speed for each measured value of the rod-shaped member 600. 600 can be distributed. Then, until one inverted holding member 410, 410a is moved above one discharge hopper among the discharge hoppers 511, ˜, 515, the rods in the one holding member 410, 410a are moved by the shutters 460, 460a. The member 600 can be prevented from falling. Further, when one holding member 410, 410a inverted above one discharge hopper is moved, the shutter 460 is opened. As a result, the rod-shaped member 600 in one holding member 410, 410a can be distributed to one discharge hopper. Furthermore, by continuing this operation, a large number of rod-shaped members 600 can be distributed at high speed.

  Further, in the rotation distribution device 400 shown in FIG. 7, even if the holding member 410 is reversed, the vicinity of both ends of the rod-shaped member 600 is held by the U-shaped member, and the rod-shaped member is opened from the opening side of the U-shaped member. The vicinity of the central portion of the rod-shaped member 600 is held by the shutter 460 so that the member 600 does not fall. When dropping the bar-shaped member 600 onto one discharge hopper, the bar-shaped member 600 in one holding member 410 is moved to one discharge hopper by moving the shutter 460 from the opening side of the U-shaped member. It can be discharged.

  On the other hand, in the rotary distribution device 400 shown in FIG. 8, even if the holding member 410a is reversed, the vicinity of the center of the bar-shaped member 600 is held by the U-shaped member, and the bar-shaped from the opening side of the U-shaped member. The vicinity of both ends of the rod-shaped member 600 is held by the shutter 460a so that the member 600 does not fall. When the rod-shaped member 600 is dropped onto one discharge hopper, the shutter 460 is moved horizontally from the opening side of the U-shaped member, so that the rod-shaped member 600 in the one holding member 410 is moved to one discharge hopper. Can be discharged. In this case, since the shutter 460a is moved horizontally, a vertical space is not required as in the case of the shaft-rotating shutter 460, and the height H1 can be further suppressed.

  In the present embodiment, the weighing units 311 to 317 and the weighing unit 317 correspond to weighing devices, the bar-shaped members 600 and 601 correspond to articles and bar-shaped members, and the discharge hoppers 511 to and the discharge hopper 515 have a plurality of discharges.
