In addition, withdrawing device 1 possesses the gas circuit for making cylinder 11 work (aircircuit) 20 (with reference to Fig. 2). Hereinafter, the formation of gas circuit 20 and the start of cylinder 11 are described.
(formation of gas circuit and the start of cylinder)
Fig. 2 is the wiring diagram of the gas circuit 20 of the cylinder 11 shown in Fig. 1. Gas circuit 20 comprises air feed path 21 and exhaust pathway 22, and wherein, air feed path 21 is the path supplying the air supplied from the supply source of pressurized air to cylinder 11, and exhaust pathway 22 is the path from cylinder 11 exhausted air. Air feed path 21 is provided with setter (regulator) 24. The exhaust pathway 22c that exhaust pathway 22 comprises the exhaust pathway 22a from the head side of cylinder 11, exhaust pathway 22b from the bar side of cylinder 11 and exhaust pathway 22a and exhaust pathway 22b merges. Specifically, in addition, gas circuit 20 has and is configured at air feed path 21 and the magnetic valve 23 of (be air feed path 21 and between exhaust pathway 22a, 22b and cylinder 11) between exhaust pathway 22 and cylinder 11.
In addition, specifically, gas circuit 20 has: the mutually different exhaust pathway 25 of air flow quantity and exhaust pathway 26 and be configured between exhaust pathway 25,26 and exhaust pathway 22 magnetic valve 27 of (being between exhaust pathway 25,26 and exhaust pathway 22c). Exhaust pathway 25 is provided with speed regulator 28. On the other hand, exhaust pathway 26 does not arrange speed regulator. Therefore, the air flow quantity on exhaust pathway 25 is less than the air flow quantity on exhaust pathway 26. In addition, end at exhaust pathway 25,26 is provided with sourdine 29. Exhaust pathway 25 carries out air release via speed regulator 28 and sourdine 29, and exhaust pathway 26 carries out air release via sourdine 29.In the present embodiment, exhaust pathway 25 is the first exhaust pathway, and exhaust pathway 26 is second row gas circuit footpath, and exhaust pathway 22 is the 3rd exhaust pathway. In addition, it is also possible to end at exhaust pathway 25,26 does not arrange sourdine 29.
Magnetic valve 23 is single-lift (that is, unidirectional drive formula) magnetic valve. In addition, magnetic valve 23 is so-called two-position-five-way solenoid valve. In the present embodiment, when magnetic valve 23 is in not switch-on regime, as shown in Figure 2, the bar side of cylinder 11 is connected with air feed path 21, and the head side of cylinder 11 is connected with exhaust pathway 22. That is, when magnetic valve 23 is in not switch-on regime, air is supplied to the bar side of cylinder 11, and from the head side exhausted air of cylinder 11, thus lifting unit 10 rises. In addition, when magnetic valve 23 is in switch-on regime, the head side of cylinder 11 is connected with air feed path 21, and the bar side of cylinder 11 is connected with exhaust pathway 22. That is, when magnetic valve 23 is in switch-on regime, air is supplied to the head side of cylinder 11, and from the bar side exhausted air of cylinder 11, thus lifting unit 10 declines.
Samely with magnetic valve 23, magnetic valve 27 is also single-lift magnetic valve. In addition, magnetic valve 27 is so-called two-position-five-way solenoid valve. In the present embodiment, when magnetic valve 27 is in not switch-on regime, as shown in Fig. 2 (A), exhaust pathway 22 is connected with exhaust pathway 25, and when magnetic valve 27 is in switch-on regime, as shown in Fig. 2 (B), exhaust pathway 22 is connected with exhaust pathway 26. Namely, when the state state that exhaust pathway 22 is connected with exhaust pathway 25 being set to the first connection state, exhaust pathway 22 is connected with exhaust pathway 26 is set to the 2nd connection state, magnetic valve 27 makes the connection state of exhaust pathway 22 be the first connection state when magnetic valve 27 is not energized, and makes the connection state of exhaust pathway 22 be the 2nd connection state when magnetic valve 27 is energized. As mentioned above, it is necessary, the air flow quantity being less than on exhaust pathway 26 due to the air flow quantity on exhaust pathway 25, therefore, the start speed of the cylinder 11 when the start velocity ratio of the cylinder 11 when being in the first connection state is in the 2nd connection state is slow. The magnetic valve 27 of present embodiment is the switching part carrying out the connection state of exhaust pathway 22 between the first connection state and the 2nd connection state switching.
In the present embodiment, when lifting unit 10 is in rising and when lifting unit 10 is in decline under the either case in these two kinds of situations, when cylinder 11 starts start, magnetic valve 27 all switches to switch-on regime, and, as shown in Fig. 2 (B), the connection state of exhaust pathway 22 turns into the 2nd connection state. In addition, in the midway of cylinder 11 start, as shown in Fig. 2 (A), the connection state of exhaust pathway 22 is switched to the first connection state by magnetic valve 27. Namely, in the present embodiment, in order to act on the impact on shock suppressor 12,13 when relaxing and make lifting unit 10 stop, in the midway of cylinder 11 start, magnetic valve 27 turn into not switch-on regime and the connection state of exhaust pathway 22 is switched to the first connection state, thus make the start speed reduction of cylinder 11.
Specifically, when magnetic valve 27 turns into have passed through the specified time after switch-on regime, magnetic valve 27 is made to turn into not switch-on regime, thus by the start speed reduction of cylinder 11. Namely, the control portion (omitting diagram) controlled by magnetic valve 27 starts at the timing register that makes making magnetic valve 27 in switch-on regime simultaneously, and, when this timing register completes timing, magnetic valve 27 is made to turn into not switch-on regime, thus by the start speed reduction of cylinder 11.Specified time in this situation is shorter than the following time, that is: the lifting unit 10 that the lifting unit 10 being in lower position is raised up to the time till arriving upper limit position on starting and is in upper limit position from starting to decline to arriving the time lower position. Such as, this specified time is shorter than the following time, that is: be raised up on the lifting unit 10 being in lower position starts the piston rod 12a front end that bar fixing part 16 contacts shock suppressor 12 be on time and starting from the lifting unit 10 being in upper limit position decline time to the piston rod 13a front end that the dynamic part 18 of limit contacts shock suppressor 13.
In addition, in the present embodiment, by exhaust pathway 25,26, magnetic valve 27, speed regulator 28 and sourdine 29 etc. form retarding mechanism 30, this retarding mechanism 30 is the mechanism making the start speed reduction of cylinder 11 in order to act on the impact on shock suppressor 12,13 when relaxing and make lifting unit 10 stop in the midway of cylinder 11 start.

Therefore, in the present embodiment, it is possible to extend the life-span of shock suppressor 12,13, thus can reduce the replacement frequency of shock suppressor 12,13. In addition, in the present embodiment, owing to making the start speed reduction of cylinder 11 in the midway of cylinder 11 start, therefore, even if shock suppressor 12,13 is close to the life-span limit, it is also possible to reduce and act on the impact on each component parts of withdrawing device 1 when making lifting unit 10 stop. In the present embodiment, therefore, even if shock suppressor 12,13 is close to the life-span limit, it is also possible to prevent the damage of each component parts of withdrawing device 1.
In the present embodiment, when magnetic valve 27 turns into switch-on regime, exhaust pathway 22 is connected with exhaust pathway 26, and when magnetic valve 27 turn into not switch-on regime time, air flow quantity is connected with exhaust pathway 22 less than the exhaust pathway 25 of exhaust pathway 26. Therefore, in the present embodiment, it is possible to be easier to and reliably realize the start speed reduction making cylinder 11 in the midway of cylinder 11 start. In addition, in the present embodiment, when magnetic valve 27 turns into non-power status, exhaust pathway 25 is connected with exhaust pathway 22, accordingly, it may be possible to the start of the cylinder 11 when making magnetic valve 27 unfavorable condition occur and cannot turn into switch-on regime slows. In the present embodiment, therefore, even if unfavorable condition occurs magnetic valve 27, it is also possible to reduce and act on the impact on other each component parts of shock suppressor 12,13 or withdrawing device 1 when making lifting unit 10 stop.
