2. Description of the Related Art A suspension type lubricating apparatus in which a delivery unit is provided at a high point of a gas station has been developed in which a lubricating hose is moved linearly in a horizontal direction to expand a lubricating range. In the refueling device of the above type, a guide rail extending linearly in the horizontal direction is disposed in a delivery unit at a high point of the gas station, and the truck is movably held on the rail, and is provided on the truck. By suspending the refueling hose through the hose outlet, the refueling hose can be smoothly and horizontally moved within the traveling range of the bogie.

[0003] Further, since the delivery unit is provided so as to be suspended from the ceiling of the gas station, for example, a guide rail or a bogie for moving the suspension position of the oil supply hose is provided in the delivery unit. In addition to the moving mechanism described above, a lifting / lowering mechanism including a hose reel around which a refueling hose is wound and a drive motor for rotating and driving the hose reel to raise / lower a refueling nozzle, and refueling drawn from the hose reel with the movement of the bogie. A rotation arm mechanism for moving the hose mounting position is provided.

[0004] The refueling nozzle is provided at a refueling position suitable for refueling by rotating the hose reel in a forward or reverse direction.
It moves up and down to each of the standby position at the height of m and the upper end position near the delivery unit. Connected to the end of the refueling hose is a switch box provided with an up switch button for raising the refueling hose from the refueling position to the standby position, a down switch for lowering the refueling nozzle from the standby position to the refueling position, a string switch, and the like. A refueling nozzle is connected to a hose at the lower end of the switch box. Therefore, when performing the refueling operation, first operate the lowering switch installed in the gas station office or the like to lower the refueling nozzle at the upper end position to the standby position, and then operate the string switch of the switch box to wait. The oil supply nozzle can be lowered by lowering the oil supply nozzle at the position to the oil supply position.

At the end of refueling, the refueling nozzle is raised from the refueling position to the standby position by operating the up switch of the switch box. Further, when raising the refueling nozzle from the standby position to the upper end position, an elevation switch installed in the office is operated.

[0006]

In the suspension type lubricating apparatus having the above construction, the lubricating hose is inserted through a hose outlet provided at the center of the bogie so that the suspended position of the lubricating hose is determined by the moving position of the bogie. Therefore, the upper end position of the refueling nozzle is just before the switch box collides with the bogie, and when the refueling nozzle is raised to the upper end position, the refueling nozzle is suspended below the switch box below the delivery unit and below the delivery unit. Will be. Note that this upper end position is set at a height where a refueling nozzle is not caught when a large vehicle (large truck, large bus, etc.) passes below the delivery unit.

However, when a fueling station is constructed on the first floor of a building or the like where the ceiling height is not sufficiently high, the height of the ceiling becomes low. Since the space dimension between the lower end of the unit and the ground is narrowed, the upper end position of the refueling nozzle is substantially lowered, and the refueling nozzle may be hooked when passing through a large vehicle and the refueling hose may be torn.

And the switch box at hand while reaching the upper end 27c
Has a hose guide that widens to allow passage of 20
I do.

This is because the hand switch box 20 is larger than the oil supply hose 13 so that when the truck 28 arrives at the upper end 27c, the hand switch box 20 can pass through the truck 28. Here, the cart 2
8 will be described. As shown in FIGS. 4 to 6,
The first frame 32 and the second frame 33 are combined, and each of the frames 32 and 33 moves along the pair of guide rails 27. In the first frame 32, horizontal rollers 34a whose positions in the width direction (Y direction) are regulated,
34b and a vertical roller 35 whose vertical position is regulated.
a, 35b.

The horizontal rollers 34a and 34b are supported by shafts 32a and 32b which stand vertically on the frame 32 and roll on the vertical portion 27d of the guide rail 27. The vertical rollers 35a and 35b are respectively supported by Y-axis shafts 36a and 3a supported by brackets 32c and 32d on the frame 32, respectively.
6b, it rolls on the horizontal portion 27e of the guide rail 27.

Also, in the second frame 33, horizontal rollers 34a, 34b,
Vertical rollers 35a and 35b are provided. A guide member 37 guides the expansion and contraction of the pair of frames 32 and 33. As shown in FIG. 7, a first fixing portion 37b having a guide rod 37a projecting in the Y direction and a guide into which the guide rod 37a is inserted. It comprises a second guide fixing portion 37d having a hole 37c, and a coil spring 38 wound around the guide rod 37a and biasing the fixing portions 37b and 37d in a direction to separate them.

A pair of fixing portions 37b and 37d
e, 37f are fixed on the first frame 32 or the second frame 32. The guide member 37 is provided between the pair of frames 32 and 33, and is disposed at both ends in the X direction. Therefore, the pair of frames 32, 33
Are slidably supported in the Y direction by guide members 37 at both ends, and are pressed in directions away from each other by the repulsive force of the coil spring 38. Therefore, the frames 32 and 33 are configured to be able to expand and contract in the Y direction according to the distance between the vertical portions 27d of the pair of guide rails 27.

Four guide rollers 39 to 42 disposed in a frame shape are rotatably supported at the central portions of the pair of frames 32 and 33. The guide rollers 39 and 40 are supported by brackets 32e and 33e of the frames 32 and 33, respectively, so as to extend in parallel with the X direction.
Reference numeral 42 denotes frames 32 and 3 extending parallel to the Y direction.
3 is mounted. As described above, the rectangular space 43 defined by the four guide rollers 39 to 42 is a hose outlet through which the oil supply hose 13 is inserted. As described above, the hose reel 11 is driven to rotate and the oil supply hose is opened. When the reel 13 is wound up or unreeled, the oil supply hose 13 is guided by the guide rollers 39 to 42.

Reference numeral 44 denotes a supporting member for supporting the guide rollers 41 and 42 so as to be movable in the X direction. As shown in FIG. 4, the frames 32 and 33 are inclined at an angle of about 30 degrees with respect to the X direction. Fixed on top. The support members 49 provided at both ends of each of the guide rollers 41 and 42 have the same shape, and have a gate shape as shown in FIG. The support member 44 has an I-shaped cross section and has guide grooves 44a on both sides.
The guide 44c includes a guide 44c having a guide 44b, and columns 44d and 44e supporting both ends of the guide 44c.

A pair of rollers 46 and 47 (indicated by chain lines in FIG. 8) that roll so as to sandwich the guide grooves 44a and 44b are rotated around shafts 45 protruding from both ends of the guide rollers 41 and 42. It is movably supported. Therefore, the cart 28 having the above-described configuration is used to move the horizontal portion 27a of the guide rail 27.
Since the distance between the pair of guide rails 27 is small while the vehicle is moving, the frames 32 and 33 of the carriage 28 are in the state shown in FIG. However, when the bogie 28 passes through the inclined portion 27b of the guide rail and reaches the upper end 27c, the distance between the pair of guide rails 27 increases, so that the guide members 27 at both ends are separated by the spring force of the coil spring 38 in the Y direction. And the horizontal rollers 34a and 34b
The frames 32 and 33 are pressed so as to roll the vertical portion 27e of the frame.

Along with this, the guide rollers 39 and 40 provided at the central portions of the frames 32 and 33 are also displaced in the direction in which they are separated from each other, and the space in the Y direction of the space 43 is widened. Also, as the frames 32 and 33 move away from each other, a pair of rollers 46 and 47 provided at both ends of the guide rollers 41 and 42 are provided.
Rolls along the guide grooves 44a ₁ and 44b ₂ of the support member 44 which is provided to be inclined with respect to the X direction, and the guide rollers 41 and 42 move in directions away from each other. As a result, the distance in the X direction between the pair of guide rollers 41 and 42 increases, and the distance in the X direction and the Y direction of the space 43 becomes larger than the distance shown in FIG.

Therefore, when the carriage 28 arrives at the upper end 27c of the guide rail 27, the guide roller 39
The space 43 defined by .about.42 is enlarged so that even the switch box 20 larger than the refueling hose 13 has the space 43.
Can be passed through. Here, a description will be given of a process executed by the control device 18 in accordance with the elevating operation of the oil supply nozzle 14 in the suspension type oil supply device having the above configuration.

First, the raising operation of the refueling nozzle 14 will be described with reference to the flowchart of FIG.
The lowering operation of the refueling nozzle 14 will be described with reference to the flowchart of FIG. In FIG. 9, when the pressing operation is input to the up switch 21A of the hand switch box 20 in step S1 (hereinafter, step is omitted), the control device 18 proceeds to S2 and turns on the limit switch 30 of the delivery unit 10. Check if it is.
This is because if the cart 28 is at the upper end 27c of the guide rail 27, the limit switch 30 is turned on.
The stop position of No. 8 is confirmed.

When the limit switch 30 is ON in S2, the process proceeds to the next S3, in which the refueling nozzle 14 is moved to the standby position B.
It is checked whether or not a standby position detection switch (not shown) of the switch box 15 for detecting that the oil supply is in the ON position. If the standby position detection switch is not ON, the process further proceeds to S4 and the refueling nozzle 14 is turned on. It is checked whether or not a refueling position detection switch (not shown) of the switch box 15 for detecting the position A is turned on.

If the refueling position detection switch is ON in S4, the process proceeds to the next S5, in which the hose lifting motor 12 is driven to rotate in the ascending direction, and the refueling hose 13 is wound by the rotation of the hose reel 11. Fueling nozzles 14 at S6 is stored in the retract and chamber 31 of deli Beri unit 10 when (see FIG. 3), i.e. the oil supply nozzle 14 is retracted position detecting switch (shown switchbox 15 when it reaches the upper end position C The motor 12 is driven until ず is turned on.

Then, as shown in FIG.
Is stored in the delivery unit 10, the drive of the motor 12 is stopped in S7. When the carriage 28 is on the upper end 27c for turning on the limit switch 30, the guide rollers 39 to 42 shown in FIG. 4 move so as to separate in the X and Y directions so as to enlarge the space 43 as described above. Therefore, even the hand switch box 20 larger than the refueling hose 13 can pass through the space 43, and the refueling nozzle 14 can be stored in the delivery unit 10.

Therefore, the delivery unit 10
If the fuel supply nozzle 14 is raised to the upper end position C when passing under the above, an accident such as the fuel supply nozzle 14 being caught can be prevented. In addition, S1 to S
If the cart 28 is at the position where the limit switch 30 is turned on as described in 7, the operator simply presses the lift switch 21A of the hand switch box 20 to raise the refueling nozzle 14 to the upper end position C at a stretch. Can be. Therefore, it is possible to prevent a fueling nozzle catching accident due to an operation delay.

When the refueling nozzle 14 is at the standby position B in S3, the process of S4 is omitted and the process of S5 is executed. When the refueling nozzle 14 is at a height position other than the refueling position A or the standby position B, for example, when the refueling nozzle is at the upper end position C, the processing of S5 to S7 is not performed and the nozzle ascending processing ends. In addition, when the limit switch 30 is off in S2, the carriage 28 is located on the horizontal portion 27a of the guide rail 27, so that the refueling nozzle 14 cannot be stored in the delivery unit 10. In that case, S
Then, it is checked whether the refueling position detection switch is on. If the refueling nozzle 14 is at the refueling position A, S9
And the motor 12 is driven to rotate in the ascending direction.
When the standby position detection switch is turned on, the flow shifts to S11 to stop the motor 12. Thereby, the fueling nozzle 14 located at the fueling position A rises to the standby position B.
In S8, if the refueling position detection switch is off, the process moves to S12 and checks whether the standby position detection switch is on. That is, if the standby position detection switch is ON in S12, the process proceeds to the above-described step S5 to raise the refueling nozzle 14 at the standby position B to the upper end position C. Therefore, in response to the operation input of the current ascending switch 21A in step S1, the nozzle ascending process is terminated,
The operation input of the current upward switch 21A in step S1 is invalidated.

Next, when lowering the refueling nozzle 14,
The control device 18 executes a nozzle lowering process shown in FIG. In FIG. 10, when the down switch 26 of the main switch box 24 is pressed in S21, the process proceeds to S22 to check whether the limit switch 30 is turned on. When the carriage 28 is on the upper end 27c for turning on the limit switch 30, the process proceeds to S23, in which the motor 12 is driven to rotate in the descending direction, and the refueling nozzle 14 is lowered.

When the refueling nozzle 14 descends to the standby position B in S24 and the standby position detection switch is turned on, the process proceeds to S25, in which the motor 12 is stopped from rotating in the downward direction.
The nozzle lowering process ends. If the limit switch 30 is off in S22, the process proceeds to S26, and if the limit switch 30 is on, the process proceeds to S23 to execute the processes of S23 to S25 described above.

However, if the storage position detection switch is off at S26, the process moves to S27 to check whether the standby position detection switch is on. Therefore, when the standby position detection switch is ON, the refueling nozzle 14 is at the standby position B, so the process proceeds to S28, in which the motor 12 is driven to rotate downward, the refueling nozzle 14 reaches the refueling position A, and the refueling position detection switch is turned on. (S29), the motor 12 is stopped.

When the standby position detection switch is off at S27, it is considered that the refueling nozzle 14 is already at the refueling position A, so that the nozzle lowering process in response to the operation input of the switch 26 of the current lowering of step S21 is ended. . In the first embodiment, the hand described in claim 1 is used.

At both ends of the carriage 61, two cushion members 82 for absorbing shock are provided, and a pair of cushion members 83 are also provided at the stopper 63. Four rollers 84 to 87 are arranged in a frame at the center of the carriage 61, and a square space 88 is formed inside. The rollers 84 and 85 extend in the X direction, and the other rollers 86 and 85
Reference numeral 87 extends in the Y direction, and each of the rollers 84 to 87 is rotatably supported by a bracket 89.

The oil supply hose 13 is inserted into a rectangular space 88 surrounded by the rollers 84 to 87, so that the oil supply hose 13 can be smoothly fed and wound by the rollers 84 to 87. Returning to FIGS. 11 to 14, the drive mechanism 53 will be described. The driving mechanism 53 is a carriage 61
Is driven up to the curved portion 60b and the vertical portion 60c of the guide rail 60 to raise the refueling nozzle 14 to the upper end position C. The drive mechanism 53 includes a drive motor 90, a wire 91 wound around a pulley 90a of the drive motor 90,
It comprises a tension mechanism 92 for eliminating slack of the wire 91 and pulleys 93 and 94 for guiding the wire 91 to the carriage.

The tension mechanism 92 is provided with a movable pulley 97 supported by a shaft 98a of a support member 98 in a support portion 96 projecting horizontally from a bracket 95 as shown in an enlarged manner in FIGS. Inside the supporting portion 96 is a coil spring 9 9 for pressing the bearing member 98 for supporting the movable pulley 97 is interposed. Therefore, when the carriage 61 moves rightward in FIG. 11, the wire 91 is pulled out , and the moving pulley 97
It is displaced in the X ₁ direction to compress the coil spring 99.

Note that a moving pulley 97 is provided on both sides of the support portion 96.
A slit 96a is provided for inserting the wire 91 when displaced in _two directions. However, the truck 61 when moving the movable pulley 97 is prevented from wire 91 sags for displacing the X ₂ direction by the pressing force of the coil spring 99 to the left. That is, the wire 91 connected to the carriage 61
Has a constant or higher tension and does not hinder the movement of the bogie 61.

When the raising switch 25 of the main switch box 24 is pressed and the hose reel 56 rotates in the winding direction and rises to a position below the carriage 61, the hose reel 56 stops and the motor of the drive mechanism 53 is stopped. 90 rotates to wind up the wire 91. Therefore, the bogie 61 moves up the curved portion 60b of the guide rail 60 by the winding operation of the wire 91, and further reaches the vertical portion 60c.

As shown in FIG. 12, the bogie 61 contacts the first limit switch 100 provided on the bracket 95, and when this is turned on, the motor 90 stops. or,
A second limit switch 102 is provided at a boundary between the horizontal portion 60a and the curved portion 60b. At that time, the hand switch box 20 connected to the lower end of the refueling hose 13 is stored in the storage room 101 formed below the drive mechanism 53. Therefore, the refueling nozzle 14 is connected to the delivery unit 50.
, And rises to the upper end position C. Therefore, a large vehicle can pass without catching the refueling nozzle 14.

Since the coil spring 99 of the tension mechanism 92 is compressed during the process of raising the refueling nozzle 14 to the upper end position C, the motor 90 is started at the next start of nozzle lowering.
There while rotating in a direction to feed the wire 91, the movable pulley 97 for displacing the X ₂ direction, not sharply truck 61 descends downward movement of the fuel filler nozzle 14 can be smoothly performed. Moreover, by using the moving pulley 97, the stroke of the moving pulley 97 becomes half of the stroke of the horizontal portion 60a of the carriage 61, and the tension mechanism 92 has a compact configuration.

Here, the nozzle ascending process and the nozzle descending process executed by the control device 18 of the second embodiment of the present invention having the above configuration will be described with reference to FIGS. In FIG. 18, first, when a pressing operation is input to the up switch 25 of the main switch box 24 in S41, the process proceeds to S42 to check whether the standby position detection switch is on.

If the refueling nozzle 14 is not at the standby position in S42, the process proceeds to S43, and if the refueling position detection switch is ON, the motor 54 for raising and lowering the hose is rotated in the ascending direction (S44). When the refueling nozzle 14 moves up from the refueling position A to the standby position B in S45, the standby position detection switch is turned on and the motor 54 is stopped (S4).
6).

When the fuel supply nozzle 14 is at the standby position B, the motor 54 for raising and lowering the hose is driven to rotate in the nozzle rising direction (S47), and the motor 90 for winding the wire is driven to rotate in the winding direction (S48). . In the next S49, it is checked whether or not the limit switch 100 is turned on by the carriage 61. When the carriage 61 is at the horizontal portion 60a of the guide rail 60 as shown in FIG. 11, the limit switch 100 is off. Therefore, the process goes to S50 to check whether the storage position (upper end position) detection switch is on. If the storage position detection switch is not turned on in S50 and the wire winding / hose winding flag is not set in the next S51, the process proceeds to S51 and both the hose winding end flag and the wire winding end flag described later are set. Check if it is done. If both flags are not set in S51, the above-described S49, S5
If the limit switch 100 is turned on in S49 and the winding end flag is not set in the wire S53 when the checks of 0 and S51 are repeated, it is determined that the winding of the wire 91 has been completed and the process proceeds to S54 to move to the wire motor 90. Is stopped, and S5
At 5, the wire winding end flag is set, and the process returns to S49.
If the wire winding end flag is not set in S53, the process of S50 is executed.

If the storage position detection is ON in S50 and the hose winding end flag is not set in S56, it is determined that winding of the refueling hose 13 has been completed, and the process proceeds to S57, where the motor 54 for raising and lowering the hose is moved. To stop. Subsequently, after setting the hose winding end flag in S58, the process returns to S49. If the hose winding end flag is set in S56, the process of S51 is executed. If both the flags are set in the above-mentioned S51, both the flags are reset in the step S52, and then the current processing is ended. When the fuel supply nozzle 14 is lowered, the control device 18 in FIG. When the down switch 26 of the box 24 is pressed, the process proceeds to S62 to check whether the storage position detection switch is on.

If the storage position detection switch is ON in S62, the flow proceeds to S63, in which the motor 54 for raising and lowering the hose is driven in the descending direction, and then in S64, the motor 90 for wire is driven in the feeding direction. Subsequently, in S65, it is checked whether or not the limit switch 102 is turned on. If the limit switch 102 is not turned on, the process proceeds to S66 to check whether or not the standby position detection switch is turned on. If the standby position detection switch is off in S66, it is checked in S67 whether both the wire feeding and hose feeding flags are set. In S68, if both flags are not set, the flow returns to S64, and the check is repeated again.

If the storage position detection switch is not on in S62, it is checked in S69 whether the standby position detection switch is on. Therefore, when the refueling nozzle 14 is at the standby position, the motor 54 for lowering the hose is driven in the descending direction in S70, and then the motor 54 is driven until the refueling position is detected in S71. When it is detected that the motor 5
4 is stopped, and the lowering process ends.

Further, in S65, the carriage 61 is
0b, the limit switch 102 is turned on, and if the wire feeding end flag is not set in S73, it is determined that the feeding of the wire 91 has been completed, the process proceeds to S74, and the feeding operation of the wire motor 90 is stopped. The end flag is set, and the process returns to S65. Also, S
When the standby position detection switch is ON at 66 and the hose feeding end flag is set at S76, it is determined that feeding of the refueling hose 13 has been completed, and the process proceeds to S77 to stop the motor 54 for raising and lowering the hose. S78
To set the hose delivery end flag and return to S65. If both flags are set in S67 described above,
After resetting both flags in S68, the current process ends.
