Description

  The present invention relates to a sorting transformer used for sorting, for example, a bundle of newspaper bundles and packed articles during transportation.

  Conventionally, a plurality of sorting rollers arranged in the conveyance direction and width direction of the article conveyance path and individually supported so as to be rotatable around a horizontal axis are brought into contact with the outer peripheral surface by a plurality of line shafts and frictionally driven simultaneously. When sorting, the sorting roller is rotated around the vertical axis, the driving force is transmitted in a state where the rotation axis of the line shaft is inclined, and the article is conveyed and discharged to the side of the conveying path, whereby the structure is 2. Description of the Related Art A sorter that performs a simple, quick and reliable sort operation is known.

As shown in FIG. 8, this known sorting transformer 500 has a plurality of spherical sorting rollers 510 arranged in the transport direction and width direction of the article transport path, and each spherical sorting roller 510 is rotatable about a horizontal axis. And a plurality of roller support frames 520 that are rotatably provided at fixed positions around a vertical axis passing through the center of the spherical sorting roller 510, and the plurality of roller support frames 520 are arranged in a spherical sorting roller 510. Are arranged in parallel to the side of each row of a rotation mechanism 530 that rotates the same direction around the vertical axis and the spherical sorting rollers 510 arranged in the width direction of the article conveyance path. A plurality of line shafts 540 that abut against the spherical outer peripheral surfaces of the rollers 510 and frictionally drive these spherical sorting rollers 510 at the same time are provided. For example, see Patent Document 1, FIG.).
Japanese Patent No. 2911809 (page 3, FIGS. 1 to 4)

  However, the known sorting transformer 500 has a problem that since the sorting roller 510 is formed in a spherical shape, the bottom of the article to be conveyed and the sorting roller 510 are in point contact with each other, and the conveying force is weak.

  Further, as shown in FIG. 9, since the sorting roller 510 is formed in a spherical shape, the contact between the sorting roller 510 and the line shaft 540 rotates even when the sorting roller 510 rotates in the transport direction, and the discharge direction. In the case of the rotation, the point contact always occurs, the frictional force is weak, the driving force transmitted to the sorting roller 510 cannot be increased, and the conveying force is weak.

  Furthermore, as shown in FIG. 10, since the sorting rollers 510 are formed in a spherical shape, the gaps between the apexes of the adjacent sorting rollers 510 are all concave portions, and the pitch between the apexes, that is, the width of the concave portion width P is twice or less. When transporting a small article, the article may incline to the left and right in the width direction, and an article with a pitch between vertices, that is, a width less than or equal to the recess width P, falls into the recess and cannot transport an article with a small width. There was a problem.

  The present invention solves the problems of the prior art as described above, and the problem to be solved by the present invention, that is, the object of the present invention is to perform a quick and reliable sorting operation with a simple structure.

Next, the sorting roller 110 and the rotation mechanism 130 of the sorting transformer 100 according to an embodiment of the present invention will be described with reference to FIGS.
As shown in FIGS. 4 and 5, each sorting roller 110 is attached to a roller support frame 120 by a roller support shaft 121 so as to be rotatable about a horizontal axis, and the roller support frame 120 is attached to the roller support shaft 121. A parallel joint shaft 122 is swingably supported on the upper part of a turning arm 124 fixed to the upper end of the roller turning shaft 123.

  The roller turning shaft 123 is supported by a bearing cylinder 125 fixed to the machine frame 103 so as to be rotatable about a vertical axis, and the sorting roller 110 is wound around the joint shaft 122 to be a roller support frame 120. And a torsion coil spring 126 interposed between the rotary arm 124 and the swivel arm 124 so as to be constantly kept in contact with the line shaft 140.

  When the line shaft 140 and the sorting roller 110 are in contact with each other, the center of the sorting roller 110 and the center of the joint shaft 122 are positioned substantially on the axis of the roller turning shaft 123.

  As shown in FIG. 3, the machine frame 103 is provided with an air cylinder 131 for simultaneously turning the plurality of sorting rollers 110, and the machine frame 103 is provided at the tip of the telescopic rod 132 of the air cylinder 131. The lower end of the rocker arm 134, which is rotatably supported at the intermediate position by the support shaft 133, is pivotally connected to the pin, and the upper end of the rocker arm 134 is rotated around one end of the relay link 135. It is pin-coupled to move freely.

  As shown in FIG. 5, the other end of the relay link 135 is pivoted around the swivel arms 124 provided corresponding to each of the plurality of sorting rollers 110 arranged in the width direction of the machine casing 103. It is rotatably connected to an intermediate position of a connecting bar 137 that is rotatably connected by a pin 136.
