【Example】

 The present invention will be described below based on an embodiment shown in the drawings. In this specification, the front means the right side of FIG. 1, the rear means the left side of the figure, the left means the back side of FIG. 1, and the right means the front side.

The first drive conveyer 1 is provided with a base frame 2, a pair of front and rear rollers 3 rotatably provided with front and rear portions of the base frame 2 with their axes oriented in the left and right directions, and the rollers 3. And an endless transport belt 4 that has been opened. One of the rollers 3 is a drive roller rotated by a motor (not shown). A processing station is provided on the first drive conveyor 1.

A driven conveyor 11 (conveyor that functions as an article standby conveyor) following the first drive conveyor 1 is provided rotatably with a base frame 12 and an axial center of the base frame 12 in the left-right direction. The free rollers 13 and 14 are provided. The free roller 13 is a large-diameter roller, and the free roller 14 is a small-diameter roller located in front of and behind the free roller 13. The free roller 13, the roller 3 on the front side of the first drive conveyor 1 and the roller 23 on the rear side of the second drive conveyor 21, which will be described later, have substantially the same diameter.

The second drive conveyor 21 that follows the driven conveyor 11 includes a base frame 22, a pair of front and rear rollers 23 that are rotatable in the front and rear portions of the base frame 22 with their axes centered in the left and right directions. It has an endless transport belt 24 that is stretched around a roller 23. One of the rollers 23 is a driving roller rotated by a motor (not shown). The upper part of the second drive conveyor 21 serves as a processing station.

Power is set such that it is located between the roller 3 on the front side of the first driving conveyor 1 and the free roller 13 and between the free roller 13 and the roller 23 on the rear side of the second driving conveyor 21. A transmission roller 30 is rotatably provided on the base frame 12 via a bearing 32.

Each of the power transmission rollers 30 has a hollow cylindrical rotating body 31 having a hollow shaft 34 having an air supply port 33 and a hollow shaft 36 having an air discharging port 35, and the hollow rotating body 31. It has an inflatable / contractible annular fluid bag 38 provided on the outer peripheral surface of the hollow rotor 31 and communicating with the hollow rotating body 31 through a communication hole 37.

An air supply pipe 41 having an electromagnetic valve 40 corresponding to each of them is connected to the hollow shaft 34 so as to allow the rotation of the hollow shaft 34, and the hollow shaft 36 is connected to the air supply pipe 41. An air discharge pipe 44 having a solenoid valve 43 corresponding to each of them is connected so as to allow the rotation of the hollow shaft 36. The air supply pipe 41 is connected to an air supply device (not shown), and the air discharge pipe 44 is connected to an air discharge device (not shown). With such a configuration, the solenoid valve 43 can be closed and the solenoid valve 40 can be opened to supply air to the fluid bag 38 to inflate the fluid bag 14, while the solenoid valve 40 can be closed and the electromagnetic valve 40 can be closed. The fluid bladder 38 can be deflated by opening the valve 43 and evacuating air from the fluid bladder 38. A switch (not shown) for controlling the fluid bladder 38 of the power transmission roller 30 on the rear side is located near an operator working on the first drive conveyor 1, and controls the fluid bladder 38 of the power transmission roller 30 on the front side. The switch (not shown) for turning on is located near the worker working on the second drive conveyor 21. The rear side fluid bladder 38 is in contact with the roller 3 of the first drive conveyor 1 and simultaneously with the free roller 13 only in the inflated state, while the front side fluid bladder 38 is in the inflated state. Only, the roller 23 of the second drive conveyor 21 is brought into contact with the free roller 13 at the same time.

[Operation of the embodiment]

 Next, the operation of the embodiment apparatus will be described. After confirming that there is no article W on the driven conveyor 11, the person working at the work station of the first drive conveyor 1 inflates the fluid bag 38 of the power transmission roller 30 on the first drive conveyor 1 side. . After that, if the first drive conveyor 1 that has been stopped for the work is driven, the article W is transferred from the first drive conveyor 1 without worrying about the working station of the second drive conveyor 21. It can be smoothly carried out to the driven conveyor 11. Then, after the article W is placed on the driven conveyor 11, the fluid bag 38 of the power transmission roller 30 on the first drive conveyor 1 side is contracted. By doing so, the next article W can be positioned at his / her work station without worrying about the state on the driven conveyor 11. A person working at the work station of the second drive conveyor 21 can position the article W on the driven conveyor 11 on the second drive conveyor 21 by the same operation as described above.

Instead of the power transmission roller 30, a roller 3 and a free roller 13 on the front side of the first drive conveyor 1 and a roller 23 and a free roller 13 on the rear side of the second drive conveyor 21 are replaced. Alternatively, the power may be transmitted via the clutch mechanism. Further, in an actual factory, a plurality of units are installed in series with the first driving conveyor 1 and the driven conveyor 11 as one unit.

[Effect of device]

 The present invention has the following effects due to the above-described configuration. The person working at the work station of the first drive conveyor makes sure that the driven conveyor of the first drive conveyor is driven after confirming that there is no article on the preceding driven conveyor, and then By driving the 1st drive conveyor that was once stopped for work, the goods can be smoothly transferred from the 1st drive conveyor to the driven conveyor without worrying about what state the work station of the 2nd drive conveyor is. You can get out. Then, by setting the driven conveyer so as not to be driven by the first driving conveyer, the next article can be positioned in the own work station without worrying about the state on the driven conveyer. Since the driven conveyor is driven by the first driving conveyor or the second driving conveyor, the synchronous operation with the first driving conveyor or the second driving conveyor is surely performed.
