(2) Overall Configuration of Distributed Supply Device As shown in FIG. 2, the distributed supply device 1 according to the present invention includes, as main components, an input unit 11, a storage unit 12, an extrusion mechanism 20, a scraping mechanism 30, and a drive control unit. 90. In the present embodiment, the storage unit 12 is disposed below the charging unit 11, the pushing mechanism 20 is provided inside the storage unit 12, and the scraping mechanism 30 is disposed in front Y of the storage unit 12.

  The article W thrown from the loading unit 11 by the operator is temporarily stored in the storage unit 12 below the loading unit 11. Next, the article W stored in the storage unit 12 is pushed forward Y by the pushing mechanism 20. The article W pushed out from the storage unit 12 is scraped out while being loosened by the scraping mechanism 30. At this time, the drive control unit 90 controls the drive of the extrusion mechanism 20. Hereinafter, each component of the dispersion | distribution supply apparatus 1 is demonstrated in detail.

(2-1) Input Unit As shown in FIG. 2, the input unit 11 for supplying the articles W to the distributed supply device 1 is a cylindrical member having upper and lower parts opened, and the size of the opening is directed downward. It is getting smaller. The lower part of the insertion part 11 is opened corresponding to a space for storing articles W in the storage part 12 described later.

In addition, as shown in FIG. 3, the storage unit 12 includes five partition walls 13 extending in the front-rear direction (Y direction and the opposite direction) at the front part (right side in FIG. 3). These partition walls 13 are arranged in parallel in the left-right direction X, and the space for storing articles W in the storage section 12 is aligned in the left-right direction X by the partition walls 13 and has six partial sections a1 having the same volume. It is divided into ~ a6.

  As shown in FIG. 2, the front portion of each partition wall portion 13 is inclined so that the upper end thereof gradually increases toward the front Y. According to this inclination, even if the loaded article W is stacked so as to straddle the upper end of the partition wall portion 13, the article W pushed by the extrusion mechanism 20 described later is left and right by the partition wall portion 13 that gradually increases. Since it is distributed to the sections a <b> 1 to a <b> 6, the article W can be hardly left at the upper end of the partition wall portion 13.

  Moreover, as shown in FIG. 1 or FIG. 3, the comb tooth 40 is provided in the open front part of the storage part 12 over the full length of the left-right direction X of the storage part 12, and as shown in FIG. In addition, its tip faces downward. According to the comb teeth 40, even when the article W is introduced in a large amount that does not fit into the partial sections a1 to a6, the article W enters the partial sections a1 to a6 when the article W is pushed out by the extrusion mechanism 20 described later. Since the unfinished article W can be prevented from moving to the front Y by the comb teeth 40, there is no possibility that the storage part 12 suddenly falls outside from the front Y. Further, when the article W is pushed out, the article W sandwiched between the extrusion mechanism 20 and the comb teeth 40 can overflow slightly from between the comb teeth 40. It is possible to prevent the movement of 20 toward the front Y from stopping before reaching a predetermined position. The comb teeth 40 are desirably provided so as to be detachable from the dispersion supply device 1 in order to facilitate cleaning. The comb teeth 40 may be a flat gate. Furthermore, the storage unit 12 may be movable in the vertical direction so that the discharge amount of the article W can be adjusted.

(2-3) Extrusion Mechanism As shown in FIG. 3, as many as the pool hopper PH of the combination weighing machine M (six cases are illustrated) are provided in the storage unit 12. It is provided corresponding to a6. As shown in FIG. 2, each push-out mechanism 20 has a rectangular bar-like member 21 extending in the front-rear direction (arrow Y and its reverse direction) and arranged in parallel with each other, and each square bar-like member 21 behind (in the reverse direction of arrow Y). And a linear motion cylinder 22 provided so as to be able to be pressed independently from each other in the front-rear direction.

  The square bar-shaped member 21 is a bar-shaped member having a square or rectangular cross-sectional shape perpendicular to the front-rear direction, and this cross-section is capable of reciprocating in the front-rear direction inside the partial sections a1-a6. It is formed slightly smaller than the cross section. Further, the front end portion and the upper portion of the square bar-shaped member 21 are stretched, and the rear portion allows the front portion of the direct acting cylinder 22 to enter when the stroke of the direct acting cylinder 22 is shortened. A hole 21a is provided. By providing the hole 21a, the entire length of the extrusion mechanism 20 in the front-rear direction can be shortened.

  The linear cylinder 22 is fixed to a square bar-like member 21 whose forward and backward rod ends are forward Y. The square bar-like member 21 reciprocates in the front-rear direction as the rod advances and retreats. For example, an air cylinder, a hydraulic cylinder, an electric cylinder, or the like can be used as the direct acting cylinder 22.

  When the linear cylinder 22 extends, the rectangular bar-shaped member 21 moves to the front Y, and the article W stored in the corresponding partial sections a1 to a6 is pushed out from the front Y of the storage unit 12 to the outside.

  In addition, as shown in FIG. 2, the square bar-shaped member 21 may provide a taper surface at the upper end portion of the front end surface in order to smoothly guide the article W input from the input unit 11 to the storage unit 12.

(2-4) Scraping Mechanism The scraping mechanism 30 is mainly configured by a needle-equipped rotating member 31, a rotary motor 32, a coupling 33, and a frame 34. Both ends of the needle-equipped rotating member 31 extending in the left-right direction X are rotatably supported by frames 34 provided at the left and right ends of the dispersion supply device 1. One end of the needle-equipped rotating member 31 is connected to the rotating shaft of the rotating motor 32 by a coupling 33.

  The rotation member 31 with a needle extends in the left-right direction X, and has a rotation shaft portion 31a whose axis is the center of rotation, and a plurality of radial members extending radially from the rotation shaft portion 31a to the axis. It is mainly comprised from the acicular member 31b (the case where it extends in four directions is shown). The needle-like member 31b is provided at predetermined intervals in the entire range of the rotating shaft portion 31a facing the storage portion 12.

  When the rotation motor 32 is rotated, the needle rotation member 31 is rotated via the coupling 33. By this rotation, the needle-like member 31b of the rotating member 31 with the needle hooks a part of the article W pushed out from the storage unit 12 by the push-out mechanism 20 at its tip, so that the articles tangled or stuck to each other. It can be scraped while loosening W. As shown in FIG. 2, the rotation direction of the rotation member 31 with the needle may be a direction in which the article W is hooked (counterclockwise in FIG. 2), or a direction in which the article W is hooked and dropped (FIG. 2). (Clockwise). The rotation direction of the rotation member 31 with the needle can be set as appropriate according to the article W.

  As shown in FIG. 2, the scraping mechanism 30 is provided with a vertical wall portion 50 a that covers the front and side of the rotating needle-equipped rotating member 31, and a lower portion of the needle-equipped rotating member 31. A cover 50 having a tapered cylindrical portion 50b is provided. According to this cover 50, the article W scraped off while being loosened by the needle-equipped rotating member 31 falls along the vertical wall portion 50a of the cover 50 and the inner wall of the cylindrical portion 50b. All W can be reliably supplied to the pool hopper PH located below.

(2-5) Drive Control Unit The drive control unit 90 includes an arithmetic processing unit such as a CPU, a storage unit such as a RAM and a ROM, and an operation unit such as a keyboard. The arithmetic processing unit reads, for example, various setting information input by the operator from a program stored in the storage unit or the operation unit, or input signals from an applied combination weighing machine, various sensors, etc. as necessary. Can be used.

  When the rod of the linear cylinder 22 of each push-out mechanism 20 is advanced and retracted by the drive control unit 90, the speed and position of the rod are driven and controlled, whereby the push-out speed and the push-out amount of the article W by each push-out mechanism 20 are controlled. Can be controlled individually.

(3) Operation The operation of the distributed supply device 1 will be described with reference to FIG.

  First, the article W thrown from the throwing part 11 is stored in the storage part 12 below. At this time, each push-out mechanism 20 controls the linear motion cylinder 22 by the drive control unit 90 in order to store as many articles W as possible in the storage unit 12, and as shown in FIG. 21 is arranged at the rearmost position.

  Next, each linear motion cylinder 22 is individually controlled to move the square bar-shaped member 21 forward Y as shown in FIG. 4B, and corresponding partial sections a <b> 1 to a <b> 6 of the storage unit 12. By rotating the rotating member 31 with the needle while rotating the article W from the outside (counterclockwise in FIG. 4), the article W pushed out from the storage unit 12 is scraped out while being loosened by the rotating member 31 with the needle. Supply to the pool hopper PH.

  Next, as shown in FIG. 4 (c), when each square bar-shaped member 21 moves to a predetermined position, the linear cylinder 22 is controlled to stop the movement of the square bar-shaped member 21 once, A new article W is loaded from 11 (see the white arrow in FIG. 4). At this time, most of the newly added articles W are deposited on the upper surface of each square bar member 21. Therefore, since the load of the additionally loaded article W is difficult to be applied to the articles W pushed out by the respective square bar-shaped members 21, the pushed out articles W are suddenly stored in the storage section 12 due to the influence of the added articles W. There is no risk of being pushed out of the room.

  Next, as shown in FIG. 4 (d), when the linear motion cylinder 22 is controlled to move each square bar-like member 21 to the rearmost position, the additionally charged article W falls into the storage unit 12. To do. Thereafter, the operation from FIG. 4A is repeated.

(4) Features of Dispersive Supply Device In the present distributed supply device 1, even if the article W is an adhesive article, the article W pushed out from the storage unit 12 by the extrusion mechanism 20 is scraped out while being loosened by the scraping mechanism 30. Therefore, the article W is supplied to the pool hopper PH as a lump, stays above the pool hopper PH and does not fall and stably supplies the plurality of pool hoppers PH of the combination weighing machine M. it can.

  Moreover, in this dispersion | distribution supply apparatus 1, since the several extrusion mechanism 20 can extrude and supply the articles | goods W with the linear cylinder 22 only with respect to the predetermined | prescribed pool hopper PH by the drive control part 90, it is a combination weighing machine. It is possible to adjust the mass of the article W supplied to each of the M pool hoppers PH to be within a predetermined range.

  Furthermore, in this dispersion | distribution supply apparatus 1, in order to extrude with each extrusion mechanism 20 the articles | goods W each accumulate | stored in the some partial divisions a1-a6 divided by the partition part 13, the corresponding partial divisions a1- When the article W stored in a6 is pushed out, the articles W in the partial sections a1 to a6 adjacent to the article W are not pushed out, and the articles W stored in the partial sections a1 to a6 are more reliably handled. Can be supplied to the pool hopper PH.

(5) Modified Example The distributed supply device 1 in the present embodiment is not limited to the one described above. For example, as shown in FIG. 6, the plurality of needle-like members 31b constituting the needle-equipped rotation member 31 extends from the rotation shaft portion 31a only in one direction orthogonal to the axis of the rotation shaft portion 31a. And you may make it the structure provided for every predetermined interval along the axial direction of the rotating shaft part 31a over the whole range which opposes the storage part 12 among the rotating shaft parts 31a.

  In the case of this structure, as shown in FIG. 5, the rotation direction of the rotation motor 32 is repeatedly switched, and the needle-like member 31 b of the rotation member 31 with the needle connected to the rotation motor 32 via the coupling 33 is The direction is swung in a predetermined angle range (in FIG. 5, from about 45 degrees from the horizontal).

  According to the swinging of the needle-shaped member 31b, the angular range of rotation of the needle-equipped rotating member 31 is narrower than that of the previous embodiment in which the needle-equipped rotating member 31 is rotated in one direction. The mechanism 30 can be made smaller. Accordingly, the distributed supply device 1 is space-saving as a whole.

  In this modified example, a transmitted light sensor 60 is provided between the pivot member 31 with the needle and the plurality of pool hoppers PH below the pivot member 31 with the needle. As shown in FIG. 5, the transmitted light sensor 60 includes a light projecting unit 60a and a light receiving unit 60b, and the front (Y direction) and the rear (reverse direction of the Y direction) of the space through which the article W falls. ) Are respectively provided with a light projecting unit 60a and a light receiving unit 60b.

  According to the transmitted light sensor 60, when the article W falls, the light incident on the light receiving unit 60b from the light projecting unit 60a is blocked by the article W, so that the amount of light received by the light receiving unit 60b is measured. Thus, it is possible to estimate the fall amount of the article W falling on each pool hopper PH. Therefore, by inputting the signals of the plurality of transmitted light sensors 60 to the drive control unit 90 and individually driving and controlling the plurality of push-out mechanisms 20 according to the amount of fall of the article W estimated from this input signal, The amount of fall of the article W falling on the pool hopper PH can be feedback controlled.

  It should be noted that the rotation angle range of the needle-equipped rotation member 31 is set to such an extent that the needle-shaped member 31b can scrape the article W pushed out of the storage portion 12, and the needle-shaped member 31b is moved upward. Instead of rotating until it faces, the angular range in which the needle-equipped rotating member 31 rotates may be made as narrow as possible. According to this, since the article W scraped out by the needle-like member 31b does not pass above the rotating shaft portion 31a, there is no possibility that the article W remains on the rotating shaft portion 31a.

  Further, since the needle-like member 31b is swung within a predetermined angle range by the rotation motor 32, the rotation motor 32 is connected via a known link mechanism that can convert the rotation motion in one direction into the rotation motion that repeats forward and reverse rotation. The rotating motor 32 may be simply rotated in one direction by connecting the rotating member 31 with the needle.

  Furthermore, as a member that scrapes out the article W pushed out from the storage unit 12 as shown in FIG. 7, a plate-like turning member in which a plate-like member 131b is provided on the turning shaft portion 31a instead of the needle-like member 31b as shown in FIG. 131 may be used. Further, the rotation shaft portion 31a itself of the rotation member 31 is moved in the vertical direction Z, the horizontal direction X parallel to the axial direction of the rotation shaft portion 31a, or the direction in which the vertical, horizontal, or rotation is appropriately combined. Also good.

  In the above-described embodiment and the modification thereof, the common scraping mechanism 30 is used for the plurality of push-out mechanisms 20, but the push-out mechanisms 30 may be individually provided in the respective push-out mechanisms 20. According to this, the amount and timing at which the articles W pushed out from the respective partial sections a1 to a6 are scraped can be adjusted by individually controlling the rotation speed and the rotation timing of each scraping mechanism 30.

  The present invention is not limited to the illustrated embodiments and modifications, and it goes without saying that various improvements and design changes are possible without departing from the spirit of the present invention.

  As described above, according to the distributed supply device of the combination weighing system according to the present invention, the article is scraped out to the hopper while loosening the article. It can be stably distributed and supplied to a plurality of hoppers of the combination weighing machine without staying above the hopper and not falling. Therefore, there is a possibility of being suitably used in the manufacturing industry field of this type of combination weighing system.
