Description

  The present invention relates to a branching facility that branches, for example, an object to be transported that has been transported on a transport path to the side of the transport path.

  Conventionally, the following configuration is provided as this type. That is, a plurality of short rollers to be rotated are arranged at a required interval in the axial direction to form a short roller row in a horizontal row, and the short roller rows are arranged in parallel in a plurality of rows. These short roller trains are configured so as to be capable of rotating in a certain angular range around the vertical axis independently for each short roller train (see, for example, Patent Document 1).

According to this conventional configuration, when the short rollers of each short roller row are in a neutral posture, the conveyed object that has entered the roller conveyor from the carry-in path is straightened as it is driven by each short roller row that rotates in the neutral posture. It is carried out to the carry-out path. When each short roller row is inclined at 45 degrees to the right, the conveyed object that has entered the roller conveyor from the carry-in path gradually turns to the left side by driving each short roller row that rotates at the right 45 ° inclination posture. However, it is transferred to the left unloading path side and unloaded. In addition, when each short roller row is inclined 45 degrees to the left, the object to be conveyed that has entered the roller conveyor from the carry-in path is gradually turned to the right side by driving each short roller row rotating in the 45 degree inclined posture to the left. However, it is transferred to the right unloading path side and unloaded.

It is configured to switch to a non-stopper position that is retracted downward with respect to the transport surface 21.

Hereinafter, the operation in the first embodiment will be described.
In normal conveyance, as shown in FIGS. 1, 2, 5, 6, and 7 (a), the swing link body 39 is swung inward by the forward / reverse drive unit 36 in the turning device 30. Thus, the roller 20 group is set in the direction toward the conveyance path 5, and the endless flat belt body 52 is rotationally driven by the drive unit 47 in the rotation driving device 40, so that the passive wheel body 45 group, the intermediate rotation shaft 41, The group of rollers 20 facing the conveyance path 5 is driven and rotated via the intermediate rotating body 43 group and the round belt 44. Further, the stopper device 60 is in a non-stopper position in which the stopper body 61 is retracted downward with respect to the main transport surface 4 and the transport surface 21 by the lifting and lowering movement unit 62.

  Accordingly, the article W to be transported that has been transported on the transport path 5 by the transport means 1 can be transferred from the main transport surface 4 by the group of rollers 3 to the transport surface 21 by the group of rollers 20 and transported straight by the group of rollers 20. And after passing the to-be-conveyed object W over the stopper apparatus 60, it can move to the main conveyance surface 4 by the roller 3 group, and can be conveyed on the conveyance path 5 by the conveyance means 1 without branching. .

  Further, when the article to be conveyed W to be branched has been transported close to the predetermined location A, the control unit S controls the lifting / lowering unit 62 of the stopper device 60 to move upward, as shown in FIG. The body 61 is set to a stopper position that protrudes upward with respect to the main transport surface 4 and the transport surface 21. Therefore, the workpiece W that has moved from the main conveyance surface 4 by the group of rollers 3 to the conveyance surface 21 by the group of rollers 20 and has reached the predetermined location A can be received by the stopper body 61. And by detecting this acceptance, the drive part 47 in the rotational drive device 40 is once stopped by control of the control part S, and the conveyance by the roller 20 group can be stopped.

  Next, under the control of the control unit S, the swing link body 39 is swung outward by the forward / reverse drive unit 36 in the turning device 30, so that the push / pull body 31 group is moved to the other side via the push / pull operation body 35. As a result, the roller bracket 22 group is reversely swung around the longitudinal axis 25 via the link body 33, and the roller 20 group is moved as shown in FIGS. 3, 4, and 7 (b). The horizontal direction C, that is, the direction toward the branch path 10 side may be used. At that time, each roller 20 is in a line contact state with the bottom surface of the conveyed object W, and therefore the group of rollers 20 can rotate backward around the vertical axis 25 with reduced frictional resistance. Two sets (two blocks) of the turning device 30 are operated simultaneously.

  In this way, by detecting that the direction of the roller 20 group has been changed by 90 degrees, the drive unit 47 in the rotation driving device 40 is driven again under the control of the control unit S, and accordingly, the conveying surface 21 by the roller 20 group. The conveyed object W is conveyed in the horizontal direction C above. As a result, the object to be conveyed W can be transferred from the conveying surface 21 by the group of rollers 20 to the branching and conveying surface 9 by the group of rollers 8, so that it can be branched on a right angle and conveyed on the branch path 10.

  In this way, the rotation drive device 40 is stopped when the transported object W on the transport path 5 is positioned at a predetermined position, and the turning device 30 moves the rollers 20 in the direction of the transport path 5 in the lateral direction C. Since the rotary drive device 40 is driven after the swivel, the branch of the transported object W to the branch path 10 can be performed directly without turning, so that it is always possible regardless of the shape and weight. It can be performed stably with a fixed posture.

  Further, the rotation drive device 40 is positioned between the adjacent rollers 20 and is rotatably disposed on the machine frame 12 side, and is positioned below each roller 20 and attached to the intermediate rotation shaft 41.

The intermediate rotation shaft 41 group is rotationally driven, and the roller 20 group can be driven and rotated via the intermediate rotation body 43 group and the round belt 44 by the rotational drive of the intermediate rotation shaft 41 group, and thus the endless flat belt body 52. only Simple construction for rotary driven, yet controlled, resulting drives the roller 20 set to change its direction at right angles shape smoothly and reliably, further endless flat belt member 52, allows the exchange easy. At that time, the endless rotating body is composed of the round belt 44, so that the rotation transmission from the intermediate rotating body 43 to the roller 20 is always performed in any direction (position) when the direction of the roller 20 is changed to a right angle. Smooth and reliable.

  Further, a large number of rollers 20 forming the conveying surface 21 are arranged in a grid pattern, and the rotation driving device 40 is positioned between the lower sides of the rollers 20 adjacent to each other in the inclined direction of 45 degrees with respect to the direction of the conveying path 5. In addition, an intermediate rotating shaft 41 that is rotatably arranged on the machine frame 12 side, and an intermediate rotating body 43 that is positioned below each roller 20 and attached to the intermediate rotating shaft 41 and interlocked with the roller 20 via a round belt 44.

It is possible to smoothly and reliably drive the group of rollers 20 whose direction is changed to a right angle while having a simple configuration and control for rotationally driving only the body 52. Furthermore, the endless flat belt body 52 can be easily exchanged, and the intermediate rotating shaft 41 group and the endless flat belt body 52 are opposed to each other in an orthogonal shape, so that the endless flat belt body 52 is attached to the intermediate rotating shaft 43. The transmission of the rotational force by the endless flat belt body 52 can always be performed appropriately and reliably.

  Then, a non-stopper position retracted downward with respect to the transport path 5 by providing a stopper device 60 that can be moved back and forth with respect to the transport path 5 at the lower position of the group of rollers 20 in the transport path 5. When the transported object W can be transported on the transport path 5 without passing through the stopper device 60 without branching, and the stopper position is projected upward with respect to the transport path 5 The transported object W can be accurately stopped at a predetermined location.
