In the stopper device of this aspect, by rotating the motor of the drive member, the stopper member rotates concentrically with the roller, and appears and disappears from the transport path.
When the motor of the driving member is rotated, the stopper member is rotated and the posture of the stopper member is changed. Therefore, depending on the rotation posture of the stopper member, the stopper member can be sunk below the conveying surface so that the conveyed object can pass therethrough, or the stopper member can be protruded from the conveying surface to be an obstacle.
The stopper device of this aspect has a support member, and at least a part of the support member is outside the roller. Therefore, by fixing the support member to another member, the stopper device can be fixed to the conveyor device. In the stopper device of this aspect, the roller keeps a state in which it can idle.

Hereinafter, embodiments of the present invention will be described.
FIG. 1 shows a conveyor device 1 according to an embodiment of the present invention. The conveyor device 1 shown in FIG. 1 is a low conveyor, and a plurality of conveying rollers 5 for conveying a conveyed object W are axially supported at predetermined intervals in a conveying direction between a pair of left and right side frames 3 arranged in parallel. It was done. The transport roller 5 is composed of a driven roller that rotates freely and a motor built-in roller that has a driving motor (not shown) built therein.
Adjacent conveyance rollers 5 are wound around a transmission belt 6. Therefore, the rotational driving force of the motor built-in roller can be transmitted to all the driven rollers.

In the conveyor device 1 of the present embodiment, the stopper device 10 is arranged as one of the transport rollers.
The stopper device 10 erects a stopper member 15 as an obstacle on the transport path of the conveyor device 1 to forcibly prevent the transport of the transport object W.

As shown in FIG. 2, the stopper device 10 of the present embodiment is composed of a main body roller 12 and a friction roller (power transmission means rotating body) 13. A stopper member 15 is provided on the main body roller 12.
As shown in FIGS. 3 and 4, the main body roller 12 has the driving member 20 built in the outer roller 17 that idles. The output portion 32 of the drive member 20 projects from both ends of the outer roller 17, and the support member 23 projects from the output portion 32.

As shown in FIG. 5, the drive member 20 has a center shaft 7 inserted through a roller (hereinafter referred to as an inner roller) 25, and a motor 21 and a speed reducer 22 are arranged around the center shaft 7. The output shaft (rotor not shown) of the motor 21 and the speed reducer 22 both rotatably surround the central shaft 7.
The output shaft 28 of the speed reducer 22 is engaged with the inner surface of the inner roller 25, and the rotational force of the motor 21 is reduced by the speed reducer 22 to rotate the inner roller 25. Output parts 32 are integrally attached to both ends of the inner roller 25, and the output part 32 rotates as the inner roller 25 rotates.

The outer shape of the output unit 32 is roughly divided into three regions. That is, the outer shape of the output portion 32 is divided into a fitting portion 33 that fits on the inner surface of the inner roller 25, a bearing holding portion 26 of a medium diameter that follows the fitting portion 33, and a stopper mounting portion 37 at the tip.
There is a spline-shaped unevenness 38 on the surface of the stopper mounting portion 37.
In the output part 32, the fitting part 33 is press-fitted into the inner surface of the inner roller 25, and the inner roller 25 and the fitting part 33 are fastened with a pin (not shown).
Therefore, the output part 32 rotates integrally with the inner roller 25.

The inside of the output portion 32 is hollow as shown in FIG. 5, the central shaft 7 is inserted into the hollow portion 53, and both ends of the central shaft 7 project from the output portion 32. In the present embodiment, the vicinity of both ends of the central shaft 7 functions as the support member 23.
The central shaft 7 is a hollow shaft, and a screw 92 is formed on the outer side of the tip portion that functions as the support member 23.
The central shaft 7 is mounted inside the output unit 32 via a bearing 40. Therefore, the output section 32 can rotate relative to the support member 23 (center axis 7).
The support member 23 is hollow as described above.
The power supply line 41 is inserted through the hollow portion 35 of the support member 23. The motor 21 arranged inside the inner roller 25 is supplied with electric power from the outside through the power supply line 41.

As a general view of the driving member 20, the bearing holding portion 26 and the stopper mounting portion 37 of the output portion 32 project from both ends of the inner roller 25. Further, a part of the central shaft 7 further projects from both ends of the output portion 32. Further, the power supply line 41 extends from one end of the central shaft 7.
Moving the eyes to the inside of the driving member 20, the motor 21 and the speed reducer 22 provided around the central shaft 7 are used as central members, and the inner roller 25 and the output portion 32 integrally attached to both ends thereof are surrounded. When referred to as a side member, the peripheral side member has a structure in which it is relatively rotatably supported around the central shaft 7 via a bearing 40.
Therefore, the inner roller 25 and the output portion 32, and the internal motor 21, speed reducer 22, and central shaft 7 are relatively rotatable.
Further, the rotational force of the speed reducer 22 is transmitted to the inner roller 25, and the motor 21 rotates to rotate the inner roller 25 and the output section 32 integrated with the inner roller 25.

As described above, the main body roller 12 has the driving member 20 built in the outer roller 17.
A bearing 50 is provided between the inner circumference of the outer roller 17 and the bearing holding portion 26 of the drive member 20, and the outer roller 17 is rotatable relative to the drive member 20.

As a general view of the main body roller 12, the stopper mounting portion 37 of the output portion 32 projects from both ends of the outer roller 17. A part of the central shaft 7 (support member 23) further projects from both ends of the output portion 32. Further, the power supply line 41 extends from the one support member 23.
When the function of the main body roller 12 is outlined, when the motor 21 of the drive member 20 rotates, the stopper mounting portion 37 of the output portion 32 protruding from both ends of the outer roller 17 rotates.
On the other hand, since the bearing 50 is interposed between the outer roller 17 and the driving member 20, the outer roller 17 can freely rotate, and even if the motor 21 in the inner roller 25 rotates, the outer roller 17 can rotate. Does not rotate.

The stopper member 15 is shaped like a banner as shown in FIG. 2, and has a rectangular main body portion 43 and connection portions 45 provided at both ends of the main body portion 43.
In the present embodiment, as shown in FIG. 4, the main body 43 and the connecting portion 45 are made separately, and the two are joined by a screw or the like not shown.
As shown in FIG. 4, the connecting portion 45 has a substantially annular tightening portion 46 and a mounting plate 51 protruding outside the tightening portion 46.
The tightening portion 46 is an annular ring with a part missing, and the folded part 55 is provided at the missing part. The folded portion 55 has a communication hole 56 as shown in FIG.
On the inner surface of the tightening portion 46, there are spline-shaped irregularities 57.

  The stopper member 15 is fixed to the main body roller 12 by inserting the tightening portion 46 into the stopper mounting portion 37 of the main body roller 12 and tightening the tightening portion 46 with a screw 42 or the like as shown in FIG. When the tightening portion 46 is attached to the stopper attaching portion 37, since the spline-shaped irregularities 38 and 57 of both are fitted, no slippage occurs between the both.

The main body 43 of the stopper member 15 is outside the outer roller 17 and is in a parallel posture with respect to the main body roller 12. Further, in the main body portion 43 of the stopper member 15, the short direction of the plane faces the center of the main body roller 12.
Since the stopper member 15 is fixed to the output portion 32 of the main body roller 12, when the internal motor 21 rotates, the stopper member 15 rotates about the central axis 7. That is, when the internal motor 21 rotates, the stopper member 15 rotates around the axis common to the outer roller 17, and concentrically rotates with the outer roller 17 outside the outer roller 17.
On the other hand, even if the stopper member 15 rotates, the outer roller 17 of the main body roller 12 does not rotate.

The friction roller 13 is a roller that has no power and rotates idly. The friction roller 13 is provided with a member 58 that increases the frictional force such as rubber.
The friction roller 13 is surface-biased to the main body roller 12 by the biasing means 77. In the present embodiment, the biasing means 77 is a torsion spring, but other biasing members such as a spiral spring or rubber may be used.

The stopper device 10 is mounted between the side frames 3 and 3, like the other transport rollers 5.
In the present embodiment, the stopper 23 is attached to the side frames 3 and 3 by inserting the support member 23 into the attachment holes 47 provided in the side frames 3 and 3 and engaging the nut 95 with the screw 92 at the tip. ing.
The height of the upper surface of the outer roller 17 of the stopper device 10 is the same as the height of the upper surface of the other conveying rollers 5. Therefore, the upper surface of the outer roller 17 constitutes the same transport surface as the other transport rollers 5.

The main body 43 of the stopper member 15 rotates concentrically around the outer roller 17 according to the rotation of the motor 21. The posture of the main body 43 changes according to the rotation of the motor 21. In the present embodiment, it is possible to take two postures such as a lying posture as shown by a chain double-dashed line in FIG. 6 and a standing posture as shown by a solid line in FIG.
Specifically, the number of rotations of the motor 21 is detected by counting pulses, the motor 21 is rotated by a predetermined number of pulses to change the standing posture to the lying posture, and the motor 21 is rotated in the reverse direction by the same number of pulses. Then, it is possible to change from the lying posture to the standing posture.

As another measure, a limit switch, a photoelectric sensor, or the like may be used as the attitude detecting means, and the motor 21 may be rotated until the stopper member 15 has a desired attitude.
Further, in the present embodiment, there is the rotation limiting member 78 that determines the limit position, and the motor 21 may be rotated until the stopper member 15 contacts the rotation limiting member 78. Since the stopper member 15 hits the rotation limiting member 78 to increase the current flowing through the motor 21, the rotation of the motor 21 may be stopped by detecting this. Further, with this point as the origin, the motor 21 may be rotated by a constant pulse to change to the standing posture.

  A friction roller 13 is arranged at the bottom of the stopper device 10. The friction roller 13 is in contact with both the surface of the outer roller 17 of the stopper member 15 and the adjacent transport roller 5.

Next, the function of the conveyor device 1 will be described.
As described above, since the plurality of conveyor rollers 5 of the conveyor device 1 are wound by the transmission belt 6 adjacent to each other, when a motor built-in roller (not shown) which is one of the conveyor rollers 5 is rotated. , All the transport rollers 5 rotate.
Further, since the friction roller (power transmission means rotating body) 13 is in contact with both the surface of the outer roller 17 of the stopper device 10 and the adjacent conveyance roller 5, the friction roller 13 functions as a friction wheel, and the conveyance roller 5 is rotated. The rotational force is transmitted to the outer roller 17 of the stopper device 10, and the outer roller 17 rotates.

When the article W is conveyed by the conveyor device 1 and the article W is moved from one end to the other end of the conveyance path of the conveyor device 1, the main body 43 of the stopper member 15 is laid down as shown in FIG. 8A. Then, the main body 43 of the stopper member 15 is lowered to a position below the conveying surface of the conveyor device 1.
As a result, there is no obstacle on the transport path, and the article W passes over the stopper device 10 and reaches the downstream side.

When it is desired to stop the article W, as shown in FIG. 8B, the main body 43 of the stopper member 15 is changed to a standing posture, and the main body 43 of the stopper member 15 is positioned above the conveying surface of the conveyor device 1. To project.
As a result, an obstacle exists on the transport path, and the article W collides with the main body 43 of the stopper member 15 and stops.

In the embodiment described above, the rotational force is transmitted to the outer roller 17 by pressing the friction roller 13 against both the outer roller 17 and the adjacent roller 5, but the outer roller 17 may be rotated by another method. ..
