Description

[Detailed description of the invention]

The present invention relates to a refueling device that allows a hanging hose to be moved vertically and mechanically. As is well known, a hose vertical movement device and a hose lateral movement device are installed in the case of a hose processing device installed at the upper part of the gas station premises, and a refueling nozzle is attached to the lower end of the hose moved by both moving devices. A refueling system that extends the refueling range for refueling automobiles is known, for example, as disclosed in Hakamakai Publication No. 51-34408 by the present applicant. In such a known refueling device, a movement switch must be operated in order to move the hanging hose vertically and laterally. It is convenient to operate the switch by placing it near the nozzle, but if the nozzle installed at the end of the hose is in the upward position, it is difficult to reach. A string is hung there, and the switch is operated by pulling the string. However, this type of public
In the mark technology, the switch is operated with a single string, so it is a switch that moves the hose up and down, and after the nozzle has descended, another switch installed near the nozzle is operated to move it horizontally. There is. Therefore, even if you want to move it horizontally, it is not easy to operate because you have to lower it first and then operate the switch. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a refueling device with good operability that can reliably move a hose up and down and move the machine without any effort even if the nozzle is located above. In the refueling device according to the present invention, the operator of the switch for moving the hanging hose, which can be moved vertically and horizontally, is placed in two locations: near the nozzle attached to the lower end of the hanging hose and at the bottom of the string suspended from near the nozzle. It is located in the place. Therefore, both vertical movement and machine movement can be operated arbitrarily from the lower part of the suspended string, and even if the nozzle is in the upper position, the operation can be performed freely. Also, since the controls are located at the bottom, they are easy to check and prevent incorrect operation. Therefore, both horizontal movement and vertical movement improve operability. In carrying out the present invention, two switches as operators may be provided at the bottom of the string, or the string itself may be configured as a switch operator, and a set of switch operators may be provided at the bottom of the string. Good too. Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the entirety of a fueling station equipped with a fueling device to which the present invention is applied, and equipment such as a printer 3 is provided inside the interior 1 of the filling station. In the outdoor area 2, a case 5 of a hose processing device is suspended from a ceiling portion 4, and a hose lateral movement device 6 is disposed on a machine movement guide 5' provided in the case 5. This lateral movement device 6 includes a roller 8, and by driving the roller 8 with a lateral movement motor M2, the lateral movement device 6 moves on the guide 5'. Limit switches SH and SG are attached to the left and right moving ends to regulate the drive of the wisteria moving device. A hose vertical moving device is provided in the blind moving device 6, and a hose reel 7 of the vertical moving device is rotated by a vertical moving motor M, and a cam switch SA, which opens and closes in conjunction with the rotation of the reel 7, is provided. SB, SC
The vertical stop position of the hose is regulated by the action of . Switch operators 30 and 31 of a hand switch for moving the hose are attached near the nozzle at the tip of the hose 9, and switch operators 32 and 33 are further suspended from a thin thread 211 below. Further, switch operators 34 and 35 of an outdoor switch for moving the hose are provided on the wall surface 4a. By operating these switch operators, the position of the refueling nozzle 10 can be changed to ceiling standby position P, (3.8h position above ground), intermediate position P2 (2.2h position above ground),
It is moved to three positions including the refueling position P3 (position h relative to the ground) and laterally to a position where refueling is easy. On the other hand, a display meter 11 for displaying the amount of oil injected, etc. is attached to the wall surface 4a facing outdoors of the gas station. Further, gasoline or the like is sucked up by a pump motor PM from a tank provided underground, and is sent to a hose 9 via a pipe 13 while being measured by a flow meter 12. Therefore,
When the nozzle 10 is lowered to the refueling position, the pump motor PM
is driven to refuel the automobile 14, and the flow meter 12
The amount of refueling measured in is displayed on the display meter. Next, the operation of this device will be explained in detail using the circuit diagrams shown in FIG. 2 and below. ○} Operation when the nozzle is in the ceiling standby position P (Figures 2 and 5) 'a} Machine movement (hose is located outside Oribe) When the outdoor switch operator 34 is pressed, the switch SF closes the contact 36 Contacts 1'' and 1''' open at the same time as the relay 1 operates and the contact 1' closes.The contacts 1'' and 1''' do not allow the nozzle to move up or down or refuel during horizontal movement. It functions as an interlock for
When the contact of relay 1 closes, the lateral movement motor rotates in the normal direction, and the hose moves to the right. When the hose moves to the end, switch SG is pushed open by the screen moving device, relay M is deenergized, and its contact M
', M'' open. When the contact M' opens, the IJ relay 1 is deenergized and the motor M2 is stopped. When the operator 34 is returned, the ratchet relay is energized and its ratchet contact H' is switched. When the operator 34 is further pressed, the IJ relay J is energized, its contact J' is closed, and its contacts J'' and J''' are opened.
Contacts J'' and J serve as an interlock to prevent the nozzle from moving up and down or from refueling while the hose is moving laterally. When contact U' of relay J closes, the motor rotates in reverse and the hose moves to the left. If the hose is moving in the opposite direction, when the operator 34 is released, the contact H' will be switched by the action of the IJ relay, and when pressed again, the hose will move in the opposite direction.'b' Press the nozzle lift/lower outdoor switch operator 35 Then, switch SP closes, relay C operates, and its contacts C' and C'' close, and contact C'
′′, 〇′′′ opens. Contact point C is a contact point to prevent the hose from rising while the hose is descending, and contact point C' is a contact point to prevent horizontal movement of the hose while the hose is descending. When contact C' closes, hose lifting motor M
, rotates forward and the hose descends. . When it descends a little, cam switch SA switches. However, since the contact C'' is closed, the relay C is self-held, the hose descends, and when it reaches the intermediate position P2, the cam switch SC is switched and the hose stops. {21 When the nozzle is at the intermediate position P2 Operation (Fig. 3, Fig. 5) {a} If the horizontal movement outdoor switch operator 34 is pressed, the above '1}

[It operates in the same way as a-. When the switch operator 32 suspended from the wire 21 is pressed, the switch SI closes, the relay Y operates, its contact Y' closes, the relay g operates, its contacts g and g are closed, and the contact closes. The contact point g' is for self-holding, and the contact point ㆆ is a contact point to prevent the direction of movement from being changed by pressing the outdoor switch operator 34 during movement. The relay 1 operates, which closes the contact g..., closes its contact r, and opens 1'' and 1. When the contact r closes, the motor M2 rotates forward, and the hose moves to the right, and when it reaches the end, the switch is activated. SG opens and the motor ground stops.'b1 When the nozzle lift outdoor switch operator 35 is pressed, switch SP closes and relay A operates, its contacts A' and A'' close, and contact A''
'． A′′′′, A′′′′′′ opens. Since the contacts A do not lower the hose, the contacts A are used to prevent the hose from moving laterally while the hose is rising. When the contact point A' closes, the hose lifting motor M rotates in the reverse direction, and the hose rises. When it rises a little, the cam switch S
C switches and is self-held by contact A''. When the ceiling standby position P is reached, the cam switch SA is switched, the relay A is deenergized, and the hose is stopped. When the switch operator 33 suspended from the wire 21 is pulled, switch SK closes, relay This causes the relay C to operate, its contacts C' and C'' to close, and the contacts C..., C to open. Then, the hose descends and when it reaches the refueling position, the cam switch SB is switched, the relay C is deenergized, and the hose is stopped. By switching the cam switch SB, the reset mechanism PX of the display meter 11 is activated, the previous oil supply amount is returned to zero, and the relay P is activated. This closes the contact P' and opens the contact P'', so that even if the outdoor switch operator 35 is pressed, the hose will not rise. In this state, the pump motor PM rotates and refueling becomes possible.
Then, the relay K operates, and the contact K' moves to the right contact in the figure, and the contacts K'', K... open. '3' Operation when the nozzle is at the refueling position P3 (Figures 4 and 5) )'a}
Even if the lateral movement outdoor switch operator 34 is pressed, the lateral movement device 6 does not move because the contact KW is open. When you press the hand switch operator 30 provided near the nozzle,
Switch SI' is closed, relay Y is activated, contact Y' is closed, relay g is activated, its contacts g and g'' are closed, and contact g'' is open. When contact g''' is closed, relay 1 is activated, its contacts r are closed, and contacts 1'' and 1'' are opened. When contact 1' closes, the motor rotates forward, the hose moves to the right, and when it reaches the end, switch SG opens and motor M2 stops. If the operator 30 is returned halfway, the hose will stop at that position. When the operator 30 is pressed again, the relay date is activated.
The ratchet contact H' switches, relay J works,
Motor M2 reverses and the hose moves in the opposite direction. Also, while the hose machine is moving, contacts 1'' and J'' of relays 1 and J are open, so pump motor PM stops and contacts 1'' and 1'' are open.
The lifting motor M, with J′′′ open, does not move. {
b) Lifting and lowering of the nozzle Even if you press the outdoor switch operator 35, the hose does not rise because the contact P'' of the relay P is open. When the switch operator 31 is pressed, the switch SK closes and the relay × operates, and its contact X' closes, relay U operates, and its contacts U', U'' close. Then, relay A works, its contacts A' and A'' close, and A river, A skin, and A' skin open,
The hose rises. When the intermediate position P2 is reached, the cam switch SC is switched and the hose is stopped. In this case, contact A'' acts to prevent relay U from self-holding. Without this contact, for example, even if the hose rises a little and cam switch SB switches, if hand switch SK is pressed, relay U is self-held and reaches intermediate position P2, and relay A is deenergized, immediately relay C is activated and the hose is lowered to the refueling position.The above is an explanation of the operation of the device of the present invention, and the following is a summary. [11 Operation when the nozzle is in the ceiling standby position P'
a} The lateral movement device 6 moves in the lateral direction only while the machine movement outdoor switch operator 34 is pressed. When it moves to the end, it stops, and when you return the control and press it again, it moves in the opposite direction. If the direction of movement is the opposite, press the operator again. 'b1 When the nozzle lift/lower outdoor switch operator 35 is pressed, the nozzle descends to intermediate position P2 and stops. '2} Operation when the nozzle is at intermediate position P2 'a}
When the lateral movement outdoor switch operator 34 is pressed, the hose moves to the end and stops when the operator 32 of the switch suspended from the vicinity of the nozzle is pressed, which is the same as the movement of '1Xa} above. If the hose is at one end, it moves to the other end and stops. When you press the lift outdoor switch operator 35 of the 'b' nozzle, it rises to the ceiling standby position and the switch operator 3 is suspended from near the nozzle.
When 3 is subtracted, it descends to the refueling level pupil P3. At the refueling position P3, the pump motor is driven and becomes ready for refueling. '3} Operation when the nozzle is at the refueling position P3 {a} Even if the lateral movement outdoor switch operator 34 is pressed, it does not move. When the hand switch operator 30 is pressed, the pump motor stops and moves laterally only while the hand switch operator 30 is pressed. When it moves to the end, it stops, and when you press the operator again, it moves in the opposite direction. Even if you press the controller again before moving to the end, it will move in the opposite direction. 'b] Even if the nozzle lift/lower outdoor switch operator 35 is pressed, the nozzle does not rise. When the hand switch operator 31 is pressed, the pump motor stops and the nozzle rises to the intermediate position. In addition, between the three positions P,
, P2, and P3, horizontal movement cannot be performed even if the horizontal movement switch operator is pressed. The above is a description of the operation of the device of the present invention. Next, an embodiment of the configuration of a hand switch operator provided near the nozzle and a switch operator suspended from the vicinity of the nozzle will be described with reference to FIGS. 6 and 7. In the embodiment shown in FIG. 6, the nozzle 10 and the switch box 20 are fixed, and the moving switch SI and its operator 30 and the lift switch SK and its operator 31 are attached. A thin wire 21 is pulled out from the switch SK, and a switch box/switch operator 33 is provided at the lower end of the string so that when the operator 33 is pulled, the switch SK closes, and the switch SI
