  Even in the above apparatus, the products conveyed in one row can be divided into three rows. However, the present invention does not give an impact to the products when the products are further divided into three rows, that is, the products and the products that are the contents. It is an object of the present invention to provide a device that can be distributed without damaging the exterior and the like, and that is simple and inexpensive.

In order to solve the above problems, a three-row sorting apparatus for products of the present invention has a width for placing and transporting products in three rows, and a belt conveyor to which the products are supplied with a predetermined interval in the center of the width, The belt conveyor is supported on the upper surface of the belt conveyor by a parallel arm and abuts the side surface of the product supplied to the center of the width of the belt conveyor while drawing an arc in the supply direction of the product. A distribution bar that swings in parallel with the conveyor and distributes the products supplied to the width central portion of the belt conveyor to the left and right columns, and passes through the central column ; after the parallel arm that supports the distribution bar end, provided at predetermined intervals in the longitudinal to the central column above the belt conveyor, characterized in that it is supported by the rotary shaft of the timing pulley to be reversed in the same direction Claim 1).

  According to the present invention, the distribution of the products into the left and right rows is performed without giving an impact to the products. That is, the sorting bar abuts on the side surface of the product supplied to the center of the width of the belt conveyor and swings on the belt conveyor in parallel with the belt conveyor while drawing an arc in the supply direction of the product. However, the left and right rows of the products are sorted so as not to give an impact to the products.

Further, in the present invention, the rear end of the parallel arm that supports the sorting bar is provided on the rotation axis of the timing pulley that is provided above and below the central row of the belt conveyor at a predetermined interval and reverses in the same direction. Since it is supported, the sorting bar can be swung in parallel with the belt conveyor with a simple configuration. That is, the both timing pulleys over a timing belt, a servo motor the timing belt, since it is sufficient to invert driven by the rotor or the like.

One form of implementation of the present invention is characterized in that a roller to said feeding direction side end portion of the product of the distribution bar (claim 2).

  According to the embodiment, even when the next product is supplied for some reason when the product is distributed by the distribution bar, the roller functions as a stopper, and the front end of the product supplied at the same time The roller travels on the surface to protect the product, and at the same time, the quick operation of the sorting bar is not hindered, and no trouble occurs in the subsequent product sorting process.

Another embodiment of the present invention is characterized in that the sorting bar has a smooth surface (claim 3) . According to one aspect of this embodiment, with the left and right columns distribution of products can be smoothly, it is not name that hurt exterior quotient goods when the sorting bar abuts the product.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 is a schematic side view of a three-row sorting apparatus according to an embodiment of the present invention, FIG. 2 is a schematic plan view of FIG. 1, FIG. 3 is a schematic front view of FIG. 1, and FIG. FIG.

  In the present invention, the product W is supplied at a predetermined interval to the center of the width of the belt conveyor 1 on which the products W are placed and conveyed in three rows.

  In the embodiment of the drawings, a supply conveyor 2 and a conveyor 3 are provided in front of the belt conveyor 1, the conveyor 3 is decelerated from a motor 4 via a V belt 5 and a pulley 6, and the supply conveyor 2 is The driving speed is higher than that of the conveyor 3 from the same motor 4 as the conveyor 3 via the V belt 7 and the pulley 8.

  Therefore, the product W that has been continuously conveyed in the adjacent state on the conveyor 3 is transferred from the conveyor 3 to the supply conveyor 2 and is conveyed at a predetermined interval from the subsequent product W, and further, the supply On the conveyor 2, the products W that are spaced apart by a predetermined interval are subsequently supplied to the center of the width of the belt conveyor 1.

  Note that the supply onto the belt conveyor 1 with a predetermined interval between the products W can be performed without using the supply conveyor 2 and the conveyor 3.

  That is, it is possible to adjust the driving speed between the supply conveyor 2 and the belt conveyor 1 as described above, and leave a predetermined interval between the products W supplied onto the belt conveyor 1. In that case, the conveyor 3 is not required.

  In the present invention, as described above, the products W supplied on the belt conveyor 1 with a predetermined interval are distributed in three rows. The belt conveyor 1 is configured to be driven from a motor 9 via a V belt 10 and a pulley 11.

  Next, a distribution bar 12 is provided on the upper surface of the belt conveyor 1 to distribute the products W supplied to the central portion of the belt conveyor 1 to the left and right rows and pass through the central row.

  The distribution bar 12 is provided at both side positions of the belt conveyor 1 from a support frame 14 provided from the machine body 13. In an embodiment of the drawings, timing pulleys 15 and 16 are provided on the support frame 14 above the central row of the belt conveyor 1 with a predetermined interval in the front and rear, and a central shaft 15a of the timing pulleys 15 and 16 is provided. 16a passes through bearings 17 and 18 provided on the support plate 14, and the rear ends of the parallel arms 19 and 20 are fixed in the horizontal direction at the lower ends of the central shafts 15a and 16a.

  Further, the shafts 24 and 25 provided on the upper portion of the support plate 23 that supports the sorting bar 12 are fitted to the bearings 21 and 22 provided at the distal ends of the parallel arms 19 and 20. Therefore, when the parallel arms 19 and 20 are swung, the sorting bar 12 and the support plate 23 are swung on the belt conveyor 1 in parallel with the belt conveyor 1. The sorting bar 12 is made of a material having a smooth surface.

  Further, a timing belt 28 is hung on the timing pulleys 15 and 16 and a drive timing pulley 27 of a servo motor 26 provided on the support frame 14.

  In the figure, 29 is a roller provided at the end of the sorting bar 12 in the product supply direction, and as described above, has the function of protecting the product W and preventing troubles when sorting the product W. Have. In the figure, reference numeral 30 denotes guide rails provided on both sides of the belt conveyor 1, and is preferably configured so that the interval can be adjusted according to the size of the product W to be distributed.

  In the above configuration, when the conveyance of the product W is detected at the predetermined position of the belt conveyor 1 and the servo motor 26 is driven in reverse, the timing pulleys 15 and 16 are driven in reverse in the same direction. At the same time, the sorting bar 12 and the support plate 23 are moved in parallel with the belt conveyor 1 while drawing an arc in the supply direction of the product W on the belt conveyor 1 by swinging the parallel arms 19 and 20. It is done.

  That is, the product W supplied at a predetermined interval to the center of the width of the belt conveyor 1 is passed to the left and right rows by the sorting bar 12 so that the product W is passed on the belt conveyor 2. Can be sorted into three rows and transported to subsequent steps.

1 is a schematic side view of a three-row sorting apparatus according to an embodiment of the present invention. FIG. 2 is a schematic plan view of FIG. 1. It is a schematic front view of FIG. It is a perspective view of the part notch main part of FIG.
