Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a reel device for winding a flexible long object such as a hose, a cord, and a wire.

(Prior Art) For example, in a reel device for a hose used for refueling at a gas station, a shaft is rotatably provided with respect to a main body plate, and a reel is integrally provided with the shaft. The shaft is normally or reversely rotated by a reversible motor attached integrally, and a hose is wound or unwound by a reel that rotates integrally with the shaft.

Then, in the final stage of winding the hose, as disclosed in the specification and the drawing of Japanese Patent Application No. 1-247699 by the applicant of the present invention, the hose stopper attached to the hose is reeled. When the guide roller that constitutes the hose outlet of the apparatus comes into contact with the guide roller, the limit switch detects it and stops the motor.

(Problems to be Solved by the Invention) As described above, when the winding of the hose is completed, the motor can be stopped by using the hose stopper. It is not easy to detect and automatically stop the motor. Then, unless the motor is automatically stopped in the state where the hose is fully unwound, for example, there is a problem that reeling in the reverse direction is started.

The present invention has been made in view of the above point, and when a reel is rotated by a motor to unwind a flexible long object, a detection means capable of automatically stopping the motor by the unwinding length is provided. It is an object of the present invention to provide a reel device provided with the reel device.

[Structure of Invention]

(Means for Solving the Problem) According to the present invention, a shaft 15 is rotatably provided on a main body plate 13, and a flexible reel winding reel 16 is integrally provided on the shaft 15. In a reel device in which the shaft 15 is rotated by a motor 18 integrally attached to the main body plate 13, a thread groove 41 is formed on the outer peripheral surface of the shaft 15, and the switch operating body 42 is formed in the thread groove 41.
Is engaged with, and the engaging portion provided on the switch operating body 42
43 is engaged movably only in the axial direction with a detent body 44 provided integrally with the main body plate 13, and is operated by the switch actuation body 42 with respect to the switch actuation body 42 so that the motor 18 is moved. This is a reel device in which switches 45 and 46 for stopping are arranged.

(Operation) According to the present invention, when the reel 16 rotates in the unwinding direction of the flexible long object and the thread groove 41 of the shaft 15 turns, the switch actuation body 42 screwed with the thread groove 41 stops. It moves axially while engaging the body 44 and actuates the switch 45 or 46 at a predetermined actuation position to stop the motor 18. This switch actuator 42
Since there is a fixed relationship between the axial position and the unwinding length of the flexible long object, the reel 16 can be stopped at the unwinding length that has been set.

(Example) Hereinafter, the present invention will be described in detail with reference to the examples shown in the drawings.

As shown in FIGS. 2 and 3, the upper mounting plate 14 of the main body plate 13 is fixed to the mounting rail 11 via the mounting bracket 12, and the shaft 15 is rotatably attached to the lower portion of the main body plate 13. A reel 16 for winding a hose, which is a flexible long member, is integrally mounted on the shaft 15. The shaft 15 includes an electric motor 18 with a speed reducer, which is provided on the main body plate 13 by a mounting plate 17.
Thus, it is rotated via the pulley 19, the belt 20, the pulley 21, and the torque limiter (mechanism for frictionally transmitting rotational torque) 22. The supply fluid flows from the swivel joint 23 fitted to the end of the shaft 15 to the inner hole of the shaft 15 and the pipe 24.
Through the hose in the reel. Further, a guide roller mounting plate 26 is integrally provided under the main body plate 13 via a mounting arm 25, and four guide rollers functioning as hose outlets are provided under the guide roller mounting plate 26.
27 is arranged in a rectangle and is rotatably supported.

As shown in FIG. 1, an inner hole 24a communicating with the pipe 24 is provided at the left end of the shaft 15. This shaft 15 has a body plate with a pair of bearings 31.
It is rotatably provided with respect to 13, and the reel 16 is
The shaft 15 is integrally provided with a screw 32. Further, the torque limiter 22 is pressed via the disc spring 37 by the flange 35 of the sleeve 34 fitted to the right end portion of the shaft 15 and integrated by the screw 33, and the nut 36 screwed to the sleeve 34. The pulley 21 is clamped between the ring plate 38 and a slip ring 39. Since the torque limiter 22 is provided, for example, when the hose wound on the reel 16 is pulled out manually, the pulley 21 that cannot rotate due to the binding force of the electric motor 18 with a reduction gear is slipped by the slip ring 39. ,
The reel 16 can be rotated with a torque not so large.

Further, as shown in FIG. 1, the shaft 15
A screw groove 41 is formed on the outer peripheral surface of the switch operating body 42, and the switch operating body 42 is screwed into the screw groove 41. Limit switches 45 and 46, which are engaged with a detent body 44 that is integrally provided so as to be movable only in the axial direction, and that actuate by the switch actuation body 42 and stop the motor 18, are provided with respect to the switch actuation body 42. It is arranged. The limit switches 45 and 46 are adjustably attached to the elongated holes 53 and 54 of the attachment plates 51 and 52 fixed to the body plate 13 by screws 55 and 56. Detection plate 5 for this limit switch 45, 46
Numerals 7 and 58 denote detection rollers that engage with the switch actuation body 42.
59,60 are provided.

The upper limit switch 45 detects the state where the hose is fully unwound and automatically stops the motor 18 to prevent the hose from being wound in the reverse direction. Further, the lower limit switch 46 is for an intermediate stop that automatically stops the motor 18 when the tip of the hose is lowered to a height where it can be pulled out by hand during electric unwinding at a gas station or the like.

Next, explaining the operation of this embodiment, the shaft 15 is rotated by the electric motor 18 via the torque limiter 22,
The reel 16 is rotated in the hose unwinding direction, and the shaft 15
When the screw groove 41 is rotated in the same direction, the switch actuation body 42 screwed with the screw groove 41 moves leftward in FIG. 1 while being engaged with the detent body 44. Then, in the intermediate unwinding state where the hose tip is unwound to a height where it can be pulled out by hand, the detection plate 58 of the switch 46 is operated to stop the motor 18, and when the hose is fully unwound, the switch 45 The rotation of the reel 16 is stopped by operating the detection plate 57 and stopping the motor 18. When winding the hose, the hose stopper (not shown) attached to the hose contacts the guide roller 27 when winding is completed, as in the conventional case. , The motor 18 is stopped. The switch actuating member 42 when the winding is completed is shown by a two-dot chain line in FIG.

〔The invention's effect〕

According to the present invention, a thread groove is formed on the outer peripheral surface of the shaft, the switch operating body is screwed into the thread groove, and the engaging portion provided on the switch operating body is engaged with the rotation stopping body, Since a switch for stopping the reel rotation motor is arranged on the switch actuation body, even when the reel turns in the direction of unwinding the flexible long object, the switch actuation body according to the unwinding length thereof. The position can be detected by the motor stop switch, and the motor can be automatically stopped in the intermediate unwinding state or the maximum unwinding state.
