  According to the first aspect of the present invention, the rectangular paper sheets fed from the preceding apparatus in the first direction are received at the transport start position in the second direction intersecting with the first direction, and then moved in the second direction. Rotate the transport roller at the transport start position in the transport device that transports in the second direction by placing it on the transport roller whose rotation axis is inclined on the alignment guide side, along the alignment guide that extends in a straight line. Having a rotating shaft in the same direction as the shaft, and being provided so as to move up and down so as to come in contact with and away from the transport roller from above, and having received a rectangular paper sheet at the transport start position; And when the rectangular paper sheet is received at the conveyance start position, the detection means for detecting that the rectangular paper sheet has moved from the conveyance start position, and the rectangular shape between the pressure roller and the conveyance roller. Move down to pinch the paper Is also the rectangular paper sheet is moved from the conveyance start position, the pressing roller is moved upwardly to release a rectangular paper sheet, it is characterized in that it comprises a control unit.

  The invention according to claim 2 is the invention according to claim 1, wherein a plurality of pressing rollers are provided at intervals less than the length of the rectangular paper sheet in the second direction at the conveyance start position. Among the individual pressing rollers, the downstream pressing roller located on the most downstream side in the second direction is disposed at the most downstream position in the second direction at the transport start position, and the detection means is configured to detect the downstream pressing force. It is arranged in the vicinity of the roller.

  In the first aspect of the present invention, when the paper sheet is received at the conveyance start position, the detection means detects it, and the control unit moves the pressing roller downward based on the detection result. As a result, the paper sheet is sandwiched between the pressing roller and the transport roller, so that the transport force by the transport roller is efficiently transmitted to the paper sheet, and as a result, the paper sheet is transported immediately in the second direction. In other words, according to the first aspect of the present invention, as soon as the paper sheet fed from the preceding apparatus in the first direction is received at the transport start position, it can be transported in the second direction. Therefore, it is possible to prevent paper sheets from staying on the transport roller and causing jamming. In addition, such an effect can be realized with a simple configuration including a pressing roller, a detection unit, and control.

  In the invention according to claim 2, the downstream pressure roller holds the paper sheet with the transport roller until the paper sheet has moved substantially completely in the second direction from the transport start position. The detecting means detects that the paper sheet is at the conveyance start position. Therefore, according to the second aspect of the present invention, the paper sheet can be held as long as possible at the transport start position, and therefore the paper sheet can be transported quickly from the transport start position in the second direction. . Therefore, it is possible to prevent paper sheets from staying at the conveyance start position and causing jamming.

  FIG. 1 is a plan view of a transfer apparatus according to an embodiment of the present invention, and FIG. 2 is a view taken along arrow II in FIG. The transport device 1 receives a rectangular paper sheet 100 that has been transported in the first direction (in the direction of the arrow X) from the transport device 9 that is a preceding device and sent out, and intersects the first direction. It is conveyed in the direction (arrow Y direction). Here, the first direction and the second direction are orthogonal to each other, but the present invention is not limited to this.

  The transport device 9 is configured to transport the paper sheet 10 on a plurality of transport belts 91. The transported paper sheet 100 is sent out onto a horizontal transport surface 11 (FIG. 2) of the transport device 1 by a feed roller 92.

  The conveyance surface 11 of the conveyance apparatus 1 is configured by a large number of conveyance rollers 12 arranged in parallel. On the conveyance surface 11, an alignment guide 13 extending linearly in the second direction is provided. Specifically, as shown in FIG. 2, the alignment guide 13 is not in contact with the lower edge portion 131 for causing the one side edge 101 of the paper sheet 100 to follow and the paper sheet 100 on the transport surface 11. And a horizontal portion 132 provided at a slight distance from the conveying surface 11 and an inclined portion 133 provided so as to be gradually lowered from the conveying device 9 side to reach the horizontal portion 132. The lower edge 131 extends linearly in the second direction. The lower edge portion 131 extends downward from the conveyance surface 11 between the adjacent conveyance rollers 12.

  All the transport rollers 12 are provided with the rotation shaft 121 inclined on the alignment guide 13 side. That is, the crossing angle α on the downstream side in the transport direction (second direction) between the rotation shaft 121 of the transport roller 12 and the lower edge 131 of the alignment guide 13 is set to be smaller than 90 degrees.

  In the present invention, the pressing roller 21 and the detection means 22 are provided at the transport start position 10 in the second direction of the transport apparatus 1 that receives the paper sheet 100 sent out from the transport apparatus 9.

  The pressing roller 21 has a rotation shaft 211 in the same direction as the rotation shaft 121 of the transport roller 12, and is provided so as to be movable up and down so as to come in contact with and separate from the transport roller 12 from above. Specifically, the pressing roller 21 is supported by the support portion 231 hanging from the tip of the arm 23 by the rotating shaft 211 being rotatably and cantilevered. The arm 23 is pivotable up and down with the base end 232 as a fulcrum. A spring 233 that biases the arm 23 to rotate upward is connected to the arm 23. A horizontal rotation shaft 234 (FIG. 1) passes through the base end portion 232, and the arm 23 can be rotated up and down by rotating the rotation shaft 234 with a solenoid 24. On the other hand, the horizontal portion 132 of the alignment guide 13 is formed with a through hole 1321 through which the lower portion of the pressing roller 21 moved downward passes.

  Here, two pressure rollers 21 are provided, and the distance between the pressure roller 21 on the upstream side in the second direction and the pressure roller 21 on the downstream side in the second direction is longer than the length of the paper sheet 100 in the second direction. It is set small.

  The detection means 22 is a pair of optical sensors 221 and 222 arranged vertically, and is provided at a position near the lower edge 131 near the pressing roller 21 on the downstream side in the second direction. The detection means 22 detects the presence of the paper sheet 100 between the optical sensors 221 and 222, and detects the absence of the paper sheet 100 between the optical sensors 221 and 222. Accordingly, the detection unit 22 detects that the paper sheet 100 has been received at the conveyance start position 10 and that the paper sheet 100 has moved from the conveyance start position 10.

  In the present invention, a control unit (not shown) for controlling the vertical movement of the pressing roller 21 based on the detection result of the detection means 22 is provided. When the paper sheet 100 is received at the conveyance start position 10, the control unit moves the pressing roller 21 downward so as to sandwich the paper sheet 100 between the paper roller 100 and the paper sheet 100. When moved from the conveyance start position 10, the pressing roller 21 is moved upward so as to be separated from the paper sheet 100.

  In the transport apparatus 1 configured as described above, the paper sheet 100 sent out from the transport apparatus 9 in the first direction is received at the transport start position 10 and transported in the second direction by the transport roller 12.

  At this time, the sheet 100 conveyed in the second direction is moved while moving toward the lower edge 131 of the alignment guide 13 because the rotation shaft 121 of the conveyance roller 12 is inclined toward the alignment guide 13. It is transported in two directions. Therefore, in the transport apparatus 1, the paper sheet 100 is transported in the second direction while the one side edge 101 is forced along the lower edge 131 of the alignment guide 13.

  And in the conveyance apparatus 1 of the said structure, since the press roller 21, the detection means 22, and the control part are provided, the paper sheet 100 received in the conveyance start position 10 is the conveyance force by the conveyance roller 12. Therefore, it is transported in the second direction as soon as it is received at the transport start position 10. That is, when the paper sheet 100 is received at the conveyance start position 10, the detection unit 22 detects it, and the control unit moves the pressing roller 21 downward based on the detection result. As a result, the paper sheet 100 is sandwiched between the pressing roller 21 and the transport roller 12, that is, the paper sheet 100 is in strong contact with the transport roller 12. As a result, the paper sheet 100 is immediately conveyed in the second direction. When the paper sheet 100 is transported and disappears from the position of the detection means 22, the detection means 22 detects this, and the control unit moves the pressing roller 21 upward based on the detection result. As a result, the conveyance start position 10 becomes ready to receive the paper sheet 100.

  In addition, since the upward movement of the pressing roller 21 is performed by the urging force of the spring 233, it is performed quickly.

  Thus, according to the transport apparatus 1 configured as described above, the paper sheet 100 sent out from the transport apparatus 9 in the first direction can be transported in the second direction as soon as it is received at the transport start position 10. . Therefore, it is possible to prevent the paper sheets 100 from staying on the transport roller 12 and causing jamming. And such an effect is realizable with simple composition which consists of press roller 21, detection means 22, and control.

  In the above-described embodiment, the pressure roller 21 on the downstream side in the second direction is close to the most downstream position in the second direction at the transport start position 10 (that is, close to the edge of the transport start position 10 on the downstream side in the second direction). It is preferable to arrange the detection means 22 in the vicinity of the pressing roller 21. According to this, the pressing roller 21 on the downstream side in the second direction causes the paper sheet 100 to move between the transport roller 12 until the paper sheet 100 has moved in the second direction substantially completely from the transport start position 10. And the detection means 22 detects that the paper sheet 100 is at the conveyance start position 10. Therefore, the paper sheet 100 can be held as long as possible at the transport start position 10, and therefore the paper sheet 100 can be transported quickly from the transport start position 10 in the second direction. Therefore, it is possible to prevent the paper sheets 100 from staying at the conveyance start position 10 and causing a jam.

  The transport device of the present invention can receive rectangular paper sheets sent out from the preceding device in the first direction and transport them quickly and smoothly in the second direction intersecting the first direction. Therefore, industrial utility value is great.

It is a top view of the conveying apparatus of one Embodiment of this invention. It is an II arrow directional view of FIG.
