Process during when starting from clutch release slave cylinder 10 to contact flange 32 to clutch release slave cylinder 10 when initial position moves (Fig. 6 (a) is to (b)), clutch release slave cylinder 10 moves and plunger rod 11 is stopped along first direction, thereby produces clutch release slave cylinder 10 with respect to the motion of plunger rod 11.Thereby die lubricant is to be discharged from clutch release slave cylinder 10 with the corresponding amount of relative travel distance.Therefore the die lubricant, being discharged from is supplied to the first pipe 13 via the second runner 12b.Meanwhile, one-way valve 25 prevent die lubricant from first flow 12a towards undiluted solution tank 2 reflux (Fig. 1).
Process during while arriving backward position to clutch release slave cylinder 10 when from clutch release slave cylinder 10 contact flange 32 (Fig. 6 (c) is to (d)), clutch release slave cylinder 10 and plunger rod 11 all move along first direction.Therefore, do not have die lubricant to be discharged from clutch release slave cylinder 10.
Next, referring to Fig. 7 and 8, the following describes for discharging the operation of the die lubricant of whole fluid Supplying apparatus.
Fig. 7 (a) shows time point t1 when linkage unit 30 starts to move along first direction.At time point t1 place, the clutch release slave cylinder 10A to 10E in initial position starts to move along first direction.
Then, at clutch release slave cylinder 10A to 10E from initial position translation approximately apart from the time point t2 of d1, clutch release slave cylinder 10B contacts respectively (Fig. 7 (b)) with 10D with 32D with flange 32B.
Again then, at clutch release slave cylinder 10A to 10E from initial position translation approximately apart from the time point t3 of d2, clutch release slave cylinder 10A contacts respectively (Fig. 8 (a)) with 10C with 32C with flange 32A.
Again then, at clutch release slave cylinder 10A to 10E from initial position translation approximately apart from the time point t4 of d3, clutch release slave cylinder 10A to 10E reaches backward position, and clutch release slave cylinder 10E contacts (Fig. 8 (b)) with flange 32E.Herein, driving mechanism 9 makes mobile unit 43 stop, thereby makes clutch release slave cylinder 10A to 10E stop.
Process during from time point t1 to time point t2, as shown in Fig. 7 (a), clutch release slave cylinder 10A to 10E moves in injector 8A to 8E and plunger rod 11A to 11E is stopped.Therefore, die lubricant is discharged from clutch release slave cylinder 10A to 10E.
From time point t2 to time point t3, as shown in Fig. 7 (b), in injector 8B and 8D, clutch release slave cylinder 10B and 10D press flange 32B and 32D, thereby plunger rod 11B and 11D are moved together with clutch release slave cylinder 10B and 10D.Therefore, die lubricant is not discharged from clutch release slave cylinder 10B and 10D.In injector 8A, 8C and 8E, clutch release slave cylinder 10A, 10C and 10E move and plunger rod 11A, 11C and 11E stop.Therefore, continue the discharge of die lubricant.
From time point t3 to time point t4, as shown in Fig. 8 (a), in injector 8A to 8D, clutch release slave cylinder 10A to 10E presses flange 32A to 32D, thereby plunger rod 11A to 11D is moved together with clutch release slave cylinder 10A to 10D.Therefore, die lubricant is not discharged from clutch release slave cylinder 10A to 10D.In injector 8E, clutch release slave cylinder 10E moves and plunger rod 11E is stopped.Therefore, continue the discharge of die lubricant.
As shown in Fig. 8 (b), clutch release slave cylinder 10A to 10E and mobile plunger bar 11A to 11E are stopped at time point t4 place.Therefore, die lubricant is not discharged from clutch release slave cylinder 10A to 10E.
This emissions operation make injector 8E with and the stroke distances d3 of clutch release slave cylinder 10E between time point t1 and time point t4 measure accordingly discharge die lubricant.The die lubricant of discharging from clutch release slave cylinder 10E is supplied to the first pipe 13E by the second runner 12b.As a result, as shown in Figure 2, a large amount of die lubricants are sprayed onto on target part 20E.
In injector 8A and 8C, die lubricant with and the corresponding amount of clutch release slave cylinder 10A and the stroke distances d2 of 10C between time point t1 and time point t3 be discharged from.From the die lubricant of clutch release slave cylinder 10A and 10C discharge, by the second runner 12b, be supplied to the first pipe 13A and 13C.As a result, the die lubricant of moderate is sprayed onto target part 20A and 20C upper (Fig. 2).
In injector 8B and 8D, die lubricant with and the corresponding amount of clutch release slave cylinder 10B and the stroke distances d1 of 10D between time point t1 and time point t2 be discharged from.From the die lubricant of clutch release slave cylinder 10B and 10D discharge, by the second runner 12b, be supplied to the first pipe 13B and 13D.As a result, the die lubricant of a small amount of is sprayed onto target part 20B and 20D upper (Fig. 2).
Next, referring to Fig. 9, the following describes for by the operation of die lubricant inhalation syringe 8A to 8E.
When clutch release slave cylinder 10A to 10E is when backward position (Fig. 9 (a)), linkage unit 30 starts to carry out along moving of second direction.Fig. 5 shows the state of clutch release slave cylinder 10A to 10E in backward position.Under this state, clutch release slave cylinder 10A to 10E contacts with flange 32A to 32E, and spring 33A to 33E is compressed.
Along with linkage unit 30 is along the moving of second direction, clutch release slave cylinder 10 moves along second direction from backward position.Herein, flange 32 is pressed by spring 33, thus plunger rod 11 together with clutch release slave cylinder 10 along second direction translation (Fig. 9 (a) and (b)).Then, when spring 33 extends substantially, clutch release slave cylinder 10 separates (Fig. 9 (c)) with flange 32, and plunger rod 11 is stopped.
Then, when clutch release slave cylinder 10 is during from backward position translation distance d3, clutch release slave cylinder 10 arrives initial positions (Fig. 9 (d)).Herein, driving mechanism 9 makes linkage unit 30 stop, thus clutch release slave cylinder 10 stop.
Process during when separating with flange 32 to clutch release slave cylinder 10 when move clutch release slave cylinder 10 beginning self reversal positions (Fig. 9 (a) is to (b)), translation by clutch release slave cylinder 10 and plunger rod 11 along second direction, die lubricant stops being inhaled in clutch release slave cylinder 10.
Process during while arriving initial position to clutch release slave cylinder 10 when separating with flange 32 from clutch release slave cylinder 10 (Fig. 9 (c) is to 9 (d)), clutch release slave cylinder 10 moves and plunger rod 11 is stopped along second direction, thereby produces clutch release slave cylinder 10 with respect to the motion of plunger rod 11.As a result, die lubricant is to be sucked clutch release slave cylinder 10 from first flow 12a with the corresponding amount of relative travel distance.Meanwhile, one-way valve 26 prevents that die lubricant from refluxing towards spray unit 6 (the first pipe 13) from the second runner 12b.
Next, referring to Figure 10 and 11, the following describes for die lubricant being sucked to the operation of whole fluid Supplying apparatus.
Figure 10 (a) shows time point t5 when linkage unit 30 starts to move along second direction.At time point t5 place, the clutch release slave cylinder 10A to 10E in backward position starts to move along second direction.And then after setting in motion, clutch release slave cylinder 10E and flange 32E separate.
Then, at clutch release slave cylinder 10A to 10E from backward position translation approximately apart from the time point t6 of d3-d2, clutch release slave cylinder 10A and 10C divide out respectively (Figure 10 (b)) with flange 32A and 32C.
At clutch release slave cylinder 10A to 10E from backward position translation approximately apart from the time point t7 of d3-d1, clutch release slave cylinder 10A and 10C divide out with flange 32B and 32D respectively.
At clutch release slave cylinder 10A to 10E from backward position translation approximately apart from the time point t8 of d3, clutch release slave cylinder 10A to 10E reaches initial position, thereby makes linkage unit 30 and clutch release slave cylinder 10A to 10E (Figure 11 (b)) stop.
Process during from time point t5 to time point t6, as shown in Figure 10 (a), in injector 8E, clutch release slave cylinder 10E is moved and plunger rod 11E stop.Therefore, die lubricant is inhaled in clutch release slave cylinder 10E.In injector 8A to 8D, because clutch release slave cylinder 10A to 10D is moved together with plunger rod 11A to 11D, die lubricant is not inhaled in clutch release slave cylinder 10A to 10D.

After mobile unit 43 contact the second flanges 45 (Figure 18 (c)), clutch release slave cylinder 10 is pressed the second flange 45, thereby along second direction mobile plunger bar 11.
Then, when clutch release slave cylinder 10 is during from initial position translation distance d6, mobile unit 43 arrives backward positions (Figure 18 (d)).Herein, driving mechanism 41 makes mobile unit 43 stop, thus plunger rod 11 stop.
From plunger rod 11, start to move along second direction when mobile unit 43 arrives backward position during process (Figure 18 (a) and (b)), plunger rod 11 moves and clutch release slave cylinder 10 stop along second direction, thereby produce plunger rod 11 with respect to the motion of clutch release slave cylinder 10, thereby die lubricant is to be discharged from clutch release slave cylinder 10 with the corresponding amount of relative travel distance.Therefore the die lubricant, being discharged from is supplied in the first pipe 13 via the second runner 12b.Meanwhile, one-way valve 25 prevents that die lubricant from refluxing towards undiluted solution tank 2 from the second runner 12b.
Next, referring to Figure 19 and 20, the following describes for discharging the operation of the die lubricant of whole fluid Supplying apparatus.

Then, in mobile unit 43 from initial position translation approximately apart from the time point t10 of d6-d5, mobile unit 43 contacts (Figure 19 (b)) with 45C with the second flange 45A.After time point t6, mobile unit 43 is pressed the second flange 45A, 45C and 45E, thereby plunger rod 11A, 11C and 11E are moved along second direction.
Again then, in mobile unit 43, from initial position, move about time point t11 apart from d6-d4, mobile unit 43 contacts (Figure 20 (a)) with 45D with the second flange 45B.After time point t11, mobile unit 43 is pressed the second flange 45A to 45E, thereby plunger rod 11A to 11E is moved along second direction.
Again then, in mobile unit 43, from initial position, move about time point t12 apart from d6, mobile unit 43 arrives backward position (Figure 20 (b)).Herein, driving mechanism 9 makes linkage unit 30 stop, thereby plunger rod 11A to 11E is stopped.
Process during from time point t9 to time point t10, as shown in Figure 19 (a), plunger rod 11E moves along second direction in injector 8E.Therefore, die lubricant is discharged from clutch release slave cylinder 10E.In injector 8A to 8D, plunger rod 11A to 11D is stopped.Therefore, from clutch release slave cylinder 10A to 10D, do not discharge die lubricant.
Process during from time point t10 to time point t11, as shown in Figure 19 (a), plunger rod 11A to 11E moves along second direction in injector 8A, 8C and 8E.Therefore, die lubricant is discharged from clutch release slave cylinder 10A, 10C and 10E.In injector 8B and 8D, plunger rod 11B and 11D are stopped.Therefore, from clutch release slave cylinder 10A and 8D, do not discharge die lubricant.
Process during from time point t11 to time point t12, as shown in Figure 20 (a), plunger rod 11A to 11E moves along second direction in injector 8A to 8E.Therefore, die lubricant is discharged from clutch release slave cylinder 10A to 10E.
As shown in Figure 20 (b), in injector 8A to 8E, plunger rod 11A to 11E is in time point t12 place's stop.Therefore, die lubricant is not discharged from clutch release slave cylinder 10A to 10E.
This emissions operation make injector 8E with and plunger rod 11E at time point t9, to the stroke distances d6 between time point t12, measure accordingly discharge die lubricant.By the die lubricant of discharging from clutch release slave cylinder 10E, be supplied to the first pipe 13E and be sprayed onto target part 20E (Fig. 2).
In injector 8A and 8C, die lubricant is discharged from clutch release slave cylinder 10A and 10C with amount corresponding to the stroke distances d5 with plunger rod 11A and 11C.From the die lubricant of clutch release slave cylinder 10A and 10C discharge, be supplied to the first pipe 13A and 13C, and be sprayed onto target part 20A and 20C upper (Fig. 2).
In injector 8B and 8D, die lubricant is discharged from clutch release slave cylinder 10B and 10D with amount corresponding to the stroke distances d4 with plunger rod 11B and 11D.From the die lubricant of clutch release slave cylinder 10B and 10D discharge, be supplied to the first pipe 13B and 13D, and be sprayed onto on target part 20E.
Next, referring to Figure 21, the following describes for by the operation of die lubricant inhalation syringe 8A to 8E.
When mobile unit 43 is when backward position (Figure 21 (a)), mobile unit 43 starts to carry out along moving of first direction.Figure 17 shows that mobile unit 43 is in backward position.Under this state, mobile unit 43 contacts with all the second flange 45A to 45E or clutch release slave cylinder 10A to 10E.
By mobile unit 43 is moved along first direction, mobile unit 43 is more near the first flange 44.Before mobile unit 43 contact the first flanges 44 (Figure 21 (b)) during process in, the motion of plunger rod 11 suspends, and does not therefore have die lubricant to suck in clutch release slave cylinder 10.
After mobile unit 43 contact the first flanges 44 (Figure 21 (c)), mobile unit 43 is pressed the first flange 44, thereby along first direction mobile plunger bar 11.
Then, when mobile unit 43 is during from backward position translation distance d6, mobile unit 43 arrives initial positions (Figure 21 (d)).Herein, driving mechanism 41 makes mobile unit 43 stop, thereby makes plunger rod 11 stop.
From plunger rod 11, start to move along first direction when mobile unit 43 arrives initial position during process (Figure 21 (a) and (b)), plunger rod 11 moves and clutch release slave cylinder 10 stop along first direction, thereby produce plunger rod 11 with respect to the motion of clutch release slave cylinder 10, therefore, die lubricant is to be inhaled in clutch release slave cylinder 10 apart from corresponding amount with relative travel.Meanwhile, one-way valve 26 prevents that die lubricant from refluxing towards spray unit 6 (the first pipe 13) from the second runner 12b.
Next, referring to Figure 22 and 23, the following describes for die lubricant being sucked to the operation of whole fluid Supplying apparatus.
