BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hose winding device used for winding an oil supply hose or the like.

[0002]

2. Description of the Related Art As a conventional hose winding device of this type, an electric motor which directly connects a motor capable of rotating forward and reverse to a hose reel and rotates the hose reel in a hose winding direction or a drawing direction by the motor is used. Things are known.

[0003]

However, in this conventional electric hose winding device, a hose reel is rotated at a low speed in a winding direction or a drawing direction by a motor. When the hose is pulled out from the reel for a long time (for example, about 20 m), it takes a long time to draw out the hose, and there is a problem that work efficiency is poor.

[0004] The present invention has been made in view of such problems of the prior art, and an object thereof is to provide a hose particularly when a hose is pulled out from a hose reel for a long time. An object of the present invention is to provide a hose winding device capable of performing a hose withdrawing operation in a short time by switching the drawer from electric to manual operation.

[0005]

In order to achieve the above object, according to the first aspect of the present invention, a hose reel for winding a hose around an outer periphery, and the hose reel is rotated in a hose winding direction or a drawing direction. To connect the motor side and the hose reel side,
Or release the connection and rotate the hose reel freely.
And a switching operation means for selectively switching the pull-out rotation of the hose reel by a motor or the pull-out rotation of the hose reel by manual operation at least at the time of pulling out the hose by operating the clutch mechanism. And the hosely
When pulling out the hose by manual operation,
Pull out the hose to prevent the reel from coasting.
To the appropriate braking force stronger than the hose winding direction
A rotation control mechanism is provided .

According to a second aspect of the present invention, the entire apparatus is mounted on a fueling vehicle, and a fueling hose is wound around a hose reel.

Further, the invention according to claim 3 is provided with a notifying device for notifying the rotation state of the hose reel in the hose winding direction and the drawing direction by the motor.

According to a fourth aspect of the present invention, there is provided a safety breaker for preventing an overcurrent for opening a power supply circuit of the motor when an overload is applied during rotation of the hose reel by the motor.

[0009]

[Operation] Motor side and hose reel by clutch mechanism
While consolidated and side and to start the motor in the forward direction, the hose reel is rotated in the winding direction via a clutch mechanism, the hose is wound around the outer periphery of the hose reel. Further, when pulling out short hose, the motor side and the hose reel side consolidated state by clutch mechanism, when to start the motor in the reverse direction, the hose reel is rotated in the pull-out direction via a clutch mechanism The hose is pulled out from the outer periphery of the hose reel.

Further, when it is desired to pull out the hose for a long time, the pull-out rotation of the hose reel by a motor or the pull-out rotation of the hose reel by manual operation is selectively switched.
By operating the clutch mechanism by switching the switching operation means to the manual operation side, the motor side and the hose reel side can be operated.
Release the consolidation of and <br/> hose reel freely rotatable state. In this state, when the hose is pulled out from the outer periphery of the hose reel by manual operation, the hose reel is freely rotated in the pulling direction. When the hose is pulled out by the manual operation, an appropriate braking force is applied to the hose reel by the rotation control mechanism, and the coasting rotation of the hose reel is prevented. For this reason, loosening of the winding state of the hose on the hose reel does not occur with the inertial rotation of the hose reel in the pull-out direction.

In addition, when the motor rotates in the winding direction and the pulling-out direction of the hose reel, the rotation state is notified by the notification device, so that there is no possibility that the hose reel is left in an abnormal rotation state. If an overload is applied during rotation of the hose reel by the motor, the power supply circuit of the motor is opened by the overcurrent preventing safety breaker, and the rotation of the motor is stopped. For this reason, it is possible to prevent the motor from rotating in the overloaded state, which may cause burnout of the motor and breakage of the hose.

The hose take-up device 7 is provided with a refueling hose 8 wound up so as to be able to be pulled out, and a nozzle 8a to be hooked on a hanger 9 at a rear portion of the tank 4 is provided at the tip thereof.

Therefore, the hose winding device 7 will be described in detail. A pair of support plates 11 are erected and fixed on the mount 10 at a predetermined interval. A hose reel 12 is rotatably supported between the support plates 11, and the delivery hose 6 is connected to a central portion of one side thereof. A connection port 13 is provided in the winding body of the hose reel 12, and the oil supply hose 8 is wound around the outer circumference of the winding body of the hose reel 12 in a state of being connected to the connection port 13.

In the vicinity of the outside of the hose reel 12, a motor 14 capable of normal and reverse rotation is provided on the upper surface of the mounting base 10. A clutch mechanism 16 is provided between the motor shaft of the motor 14 and the rotation shaft 15 of the hose reel 12, and includes a pair of clutch boards 17, 18 which are movably opposed to each other. On the outer surface of the left support plate 11, the clutch mechanism 1

It is supported so as to be able to swing through 20. By operating the clutch lever 19 to the ON position or the OFF position, the driven-side clutch disc 18
It is moved to a position where it comes into contact with or separates from the drive-side clutch board 17 via the operating ring 21.

When the oil supply hose 8 is pulled out from the hose reel 12, the clutch levers 19 are operated to bring the two clutch disks 17, 18 into contact with each other, and the motor 14 rotates the hose reel 12 in the pull-out direction. And a method of pulling out the oil supply hose 8 from the outer periphery of the hose reel 12 by manual operation while freely rotating the hose reel 12 while operating the clutch levers 19 and 18 by operating the clutch lever 19. I'm sorry.

As shown in FIG. 3, a rotation control mechanism 22 is provided on the rotation shaft 15 of the hose reel 12, and when the oil supply hose 8 is pulled out by manual operation, the rotation control mechanism 22 is used. The inertia rotation of the hose reel 12 is prevented. That is, the rotating shaft 15
Is equipped with a brake drum 23. A brake shoe 24, one end of which is fixed and the other end of which is a free end, is disposed so as to wind around the drum 23, and a brake lining 25 which comes into contact with the drum 23 is attached to the inner peripheral surface thereof. I have. And the support arm 20
An adjusting bolt 27 is attached to the mounting plate 26 fixed to the nut 2.
The spring 29 is stretched between the tip of the adjustment bolt 27 and the free end of the brake shoe 24. Accordingly, the brake shoe 24 is pulled clockwise in FIG. 3 by the urging force of the spring 29 adjusted by the adjustment bolt 27, whereby the brake lining 25 is pressed against the brake drum 23, and the hose reel Twelve rotations are braked.

In this embodiment, the direction in which the brake shoe 24 is pulled by the spring 29 is as follows.
The hose reel 12 is configured to be in the same direction as the hose drawing direction X. Therefore, when the hose reel 12 is rotated in the hose withdrawing direction X, the brake shoe 24 pulls in the direction of compressing and urging the spring 29 via the brake lining 25 with the rotation of the brake drum 23 in the same direction. Stretched. Contact, hose reel 12
Thus, an appropriate braking force, which is adjusted by the adjusting bolt 27 and is stronger than the hose winding direction Y, is applied. Therefore, especially when the refueling hose 8 is pulled out by manual operation, the hose reel 12 is prevented from coasting in the pulling-out direction to prevent the rewinding state of the refueling hose 8 from being loosened on the hose reel 12. Can be.

On the other hand, when the hose reel 12 is rotated in the hose winding direction Y, the direction in which the brake shoe 24 pulls and releases the spring 29 via the brake lining 25 with the rotation of the brake drum 23 in the same direction. , Only a weak braking force is applied to the hose reel 12. Therefore, when the hose 14 is rotated in the winding direction by the motor 14 and the oil supply hose 8 is wound, it is possible to prevent a large load from being applied to the motor 14.

A cover 30 is detachably attached to the outer surface of the left support plate 11, and the cover mechanism 30 allows the clutch mechanism 16 and the rotation control mechanism 22 to be attached.
Is covered. Main switch 31 for driving the reel
Is provided on the cover 30 so that the motor 14 can be started by operating the main switch 31. On the other hand, a switching switch 32 is attached to the right support plate 11, and three push buttons 32a, 32b, 32c for rotating the motor 14 forward, backward or stop are provided on the front surface thereof.

Next, a description will be given of a drive circuit of the hose winding device configured as described above. As shown in FIG.
A fuse 34, a contact 35 a of a relay 35, and a pump motor 36 for driving the pump 5 are connected in series via a terminal 37 between the power supply terminal 33 and the ground. When an ignition switch (not shown) provided is turned on, a current is supplied to the power supply terminal 33.

Between a power supply terminal of the pump motor 36, a key-operated pump start switch 38 having a key insertion port P provided on one side surface of a protective cover C for protecting instruments, and a coil 35b of the relay 35 Are connected in series, and when the start switch 38 is turned on, the contact 3 of the relay 35
5a is closed and the pump motor 36 is started. The tank 4 is connected between the power supply terminals of the pump motor 36.
A lamp 40 for illuminating a refueling meter 39 provided at a rear portion is connected via a terminal 37.

A safety breaker 41 for preventing overcurrent, a switching switch 32 of the hose winding device 7, a main switch 31, and a motor 14 are connected in series between the power supply terminal 33 and the ground. When the switch 31 is turned on and the forward or reverse rotation push buttons 32a, 32b of the switching switch 32 are turned on, the motor 14 is rotated forward or reverse, and the hose reel 12 is moved in the hose winding direction Y or the hose drawing direction X. Rotated. When the motor 14 rotates the hose reel 12, the oil supply hose 8 comes into contact with, for example, a part of the bed 3 and the motor 1.
When an overload is applied to the motor 4, the power supply circuit of the motor 14 is opened by the safety breaker 41.

Further, a pair of notification devices 42 and 43, such as a buzzer, provided in the driver's seat 2 are connected between the power supply terminals of the motor 14 and the ground. When the motor 14 rotates in the hose winding direction due to the forward rotation of the motor 14, the one notification device 42 performs a notification operation, and when the hose reel 12 rotates in the hose pulling direction due to the reverse rotation of the motor 14, The other notification device 43 performs a notification operation.

Next, the operation of the thus configured hose winding device will be described.

When refueling using the hose winding device 7, first, the ignition switch of the driver's seat 2 is turned on, and the key insertion provided on one side of the protection cover C is inserted. The start switch 38 is turned on by inserting and rotating a key in the mouth P. When the start switch 38 is turned on, the pump motor 36 is started, and the pump 5 is driven.
Oil such as kerosene in the tank 4 is sent out to the nozzle 8a via the delivery hose 6, the hose reel 12, and the oil supply hose 8. And, the stop push button 32c of the switching switch 32
After confirming that the switch is on, the main switch 3
Turn 1 on. At this time, if the forward or reverse rotation push buttons 32a, 32b of the switching switch 32 are erroneously turned on, the motor reel 14 rotates the hose reel 12 carelessly. Since the provided notification devices 42 and 43 perform the notification operation, the abnormal rotation state of the hose reel 12 can be easily known, and the rotation can be immediately stopped.

Thereafter, when the oil supply hose 8 is pulled out from the hose reel 12 shortly, when the clutch lever 19 of the clutch mechanism 16 is swung to the ON side, that is, the electric operation side, the motor 14 and the hose reel 12 are operatively connected. Is done. Then, when the reverse rotation side push button 32b of the switching switch 32 is turned on while pulling the oil supply hose 8 from the hose reel 12 with the nozzle 8a kept hooked on the hanger 9, the motor 14 is rotated in the reverse direction, Hose reel 1
2 is rotated in the pull-out direction via the clutch mechanism 16.
Accordingly, the oil supply hose 8 can be pulled out a predetermined amount lightly from the hose reel 12 until the stop push button 32c of the switching switch 32 is turned on and the rotation of the motor 14 is stopped.

On the other hand, from the hose reel 12 to the oil supply hose 8
When the clutch lever 19 of the clutch mechanism 16 is pivoted to the off side, that is, to the manual operation side, the operative connection between the motor 14 and the hose reel 12 is released. In this state, when the nozzle 8a is detached from the hanger 9 and the oil supply hose 8 is pulled out from the outer periphery of the hose reel 12 at a walking speed, the hose reel 12 is freely rotated in the pulling-out direction in accordance with the pulling-out speed. Therefore,
The withdrawal of the refueling hose 8 can be performed in a short time by a manual operation without electric power, and the working efficiency can be improved.

When the oil supply hose 8 is pulled out by the manual operation, a proper braking force is applied to the hose reel 12 by the rotation control mechanism 22 to prevent the hose reel 12 from rotating by inertia. For this reason, the winding state of the oil supply hose 8 on the hose reel 12 does not become loose due to the inertial rotation of the hose reel 12 in the pull-out direction. Therefore, it is possible to reliably prevent a problem that it is difficult to wind the oil supply hose 8 in the aligned state thereafter.

Then, the refueling hose 8 is pulled out by a predetermined amount, the nozzle 8a is carried to a predetermined refueling point, and refueling is performed by operating the nozzle lever.

Thereafter, the oil supply hose 8 is connected to the hose reel 12.
In the case where the nozzle 8a is hung on the hanger 9, the clutch lever 1 of the clutch mechanism 16
When the knob 9 is swung to the ON side, the motor 14 and the hose reel 12 are operatively connected. In this state, when the forward rotation side push button 32a of the switching switch 32 is turned on, the motor 14 is rotated in the forward direction, and the hose reel 12 is moved to the clutch mechanism 1.
6 is rotated in the winding direction. Accordingly, if the refueling hose 8 is lightly guided and guided, the refueling hose 8 can be wound around the outer periphery of the hose reel 12 in an aligned state.

When the hose 14 is rotated by the motor 14 in the winding direction, if the oil supply hose 8 comes into contact with a part of the carrier 3 and the motor 14 is overloaded, the safety breaker 41 operates and the power supply circuit of the motor 14 is opened. Therefore, the motor 14 remains overloaded.
Is continued, the risk of the motor 14 being burned or the oil supply hose 8 or the hose reel 12 being damaged can be reliably prevented.

The present invention is not limited to the configuration of the above-described embodiment. For example, the specific configurations of the clutch mechanism 16 and the rotation control mechanism 22 may be appropriately changed, or the present invention may be applied to a hose for supplying water or hot water. For example, it can be implemented on a winding device.
The design can be arbitrarily changed without departing from the spirit of the present invention.

The rotation control mechanism 2 in the above embodiment
Although the structure 2 is simple, the braking force on the rotating body can be changed appropriately and effectively according to the change of the rotating direction of the rotating body. In addition to the device, the present invention can be embodied and implemented in other devices that require this type of rotation control.
