Reel cage motion arm 89 can be arranged rotationally centered by turning cylinder (not shown).As shown in Figure 5, in reel cage motion arm 89 be provided with on the end of end opposite side of this turning cylinder, be provided with operating portion 89A.Operating portion 89A can make a coil holder 72 leave other coil holder 72.That is, reel cage motion arm 89 carries out opening the operation of reel cage arm 71 in order to the package 45 of taking off full volume from reel cage 70, or in order to new bobbin 48 is installed to operation reel cage 70 carrying out closed reel cage arm 71.

As shown in Figure 2, take off the package 45 of full volume from reel cage 70 as being used for carrying out and being directed to the structure of the action of doffing of package carrier 84, doffer 60 possesses doffing mechanism 61.

Package carrier 84 is described.Package carrier 84 possesses for making the rake 81 of package 45 rolling movement and interim mounting portion 82 of loading package 45.Mounting portion 82 configures continuously with an end of rake 81.Rake 81 and mounting portion 82 all with the circumferential contact of package 45 form.Rake 81 and mounting portion 82 are configured on the position lower than coil holder 72.

In this example, mounting portion 82 forms conveyer, along the direction conveyance package 45 that multiple spinning unit 2 arranges.That is, conveyer transports the package 45 being discharged to mounting portion 82 by doffer 60 continuously.The transporting operation of conveyer is controlled by the control signal from body control setup 30.

Doffing mechanism 61 has swivel arm (moving part) 62, electrical motor 63 and package support (support) 65 as keystone configuration.Package support 65 supports package 45.Package support 65 can receive moving between the 1st position P1 (with reference to Fig. 5), the 2nd position P2 (with reference to Fig. 6) transferring the package 45 received at the 1st position P1 and position of readiness P0 (with reference to Fig. 4) of package 45 by swivel arm 62.

Swivel arm 62 such as rotates counterclockwise in Figure 5 under the effect of the propulsive effort of electrical motor 63.Thus, doffing mechanism 61 is advanced towards wind2 13 from the chassis 4 that doffs, make the top (package support 65) of doffing mechanism 61 near package 45 (with reference to Fig. 5).In other words, swivel arm 62 makes package support 65 move to the 1st position P1 from position of readiness P0 by rotating counterclockwise.

Swivel arm 62 such as rotates clockwise in the diagram under the effect of the propulsive effort of electrical motor 63.Thus, doffing mechanism 61 is moved towards the chassis 4 that doffs, make the top of doffing mechanism 61 (package support 65) away from the package 45 be positioned in mounting portion 82.In other words, swivel arm 62 makes package support 65 move to the 2nd position P2 from the 1st position P1 by rotating counterclockwise, and moves to position of readiness P0 (with reference to Fig. 4) from the 2nd position P2.Position of readiness P0 is the position that package support 65 does not contact with the package 45 transferring mounting portion 82 at the 2nd position P2.In this example, recurrence position when homeposition when package support 65 sets out towards the 1st position P1 by position of readiness P0 and package support 65 are returned from the 2nd position P2 etc. is set in same position.But homeposition and recurrence position also can be different.Position of readiness P0 also can be the region of package support 65 when being present on the position that do not contact with the package 45 in mounting portion 82.

Package support 65 can contact with the package 45 under the state remained on coil holder 72 by turning to top.Thus, package support 65 can make the inertial rotation of package 45 stop.Further, package 45 is directed to rake 81 by the weight limit of package 45 that package support 65 side supporting receives from reel cage 70.And package support 65 also continues to support this package 45 after package 45 contacts with rake 81, along rake 81, package 45 is directed to mounting portion 82.

Limit as being used for the structure that action placed by bobbin, doffer 60 possesses test section 95, doffer control part 31 and informing portion 96 as shown in Figure 3.

Test section 95 is formed with detecting obstacle, is fixed on framework 4A.Test section 95 test example is as being positioned at package 45 on reel cage 70 as obstacle.Test section 95 is such as optical pickocff, by detecting the light that the package 45 be positioned on reel cage 70 is reflected, or detecting the light blocked by the package 45 be positioned on reel cage 70, can detect the package 45 be positioned on reel cage 70.Test section 95 will represent that the Detection Information of testing result exports to doffer control part 31.In addition, the obstacle becoming the detected object of test section 95 is not limited to package 45.Test section 95 also can detect the reel cage 70 providing the target location of bobbin 48 and the object being positioned at its periphery.

Doffer control part 31 performs the various control treatment in the doffer 60 such as the movement of package support 65 and the mobile of bobbin maintaining part 52.Body control setup 30 is made up of CPU (CentralProcessing Unit), ROM (Read Only Memory), RAM (Random AccessMemory) and hardware etc.The control that doffer control part 31 is implemented loads in RAM by the program be such as kept in ROM, performs realize with CPU.

If doffer control part 31 receives the Detection Information exported from test section 95, then judge on reel cage 70 with or without package 45 according to this Detection Information.Be specially, doffer control part 31 judges on reel cage 70 with or without package 45 after package support 65 is moved to position of readiness P0 by swivel arm 62.Also package support 65 is comprised when being positioned at position of readiness P0 in definition after package support 65 moves to position of readiness P0.That is, doffer control part 31 also can determine whether package 45 while package support 65 is positioned at position of readiness P0.Package support 65 is positioned at this situation of position of readiness P0 can according to the control signal being used for controlling the electrical motor 63 making package support 65 movement, or detects the detection signal that package support 65 is positioned at the origin sensor (not shown) of position of readiness P0 and obtain.

Doffer control part 31, when being judged to be reel cage 70 has package 45, makes the supply action of Cylinder feeder mechanism 50 control bobbin feed mechanism 50 with stopping (forbidding).That is, there is package 45 in doffer control part 31 on reel cage 70, reel cage 70 is when being in the state that can not receive bobbin 48, makes the supply action (bobbin placement action) of Cylinder feeder mechanism 50 stoppingly control bobbin feed mechanism 50.Doffer control part 31 when being judged to be reel cage 70 to exist package 45, to informing portion 96 output abnormality information.

Doffer control part 31, when being judged to be reel cage 70 does not have package 45, makes Cylinder feeder mechanism 50 control with carrying out supply action.That is, there is not package 45 in doffer control part 31 on reel cage 70, reel cage 70 is when being in the state that can accept bobbin 48, provides bobbin 48 by the bobbin maintaining part 52 of Cylinder feeder mechanism 50 to reel cage 70.

Informing portion 96 exists obstacle on reel cage 70, inform and this situation abnormal occurs.That is, if informing portion 96 receives the abnormal information exported from doffer control part 31, then inform and abnormal this situation occurs.Informing portion 96 is such as lamp.In addition, informing portion 96 both can be the n segment display n of the error code of display regulation, also can be buzzer phone etc.

Doff action and bobbin placement action in doffer 60 is then described with reference to Fig. 4 ~ Fig. 6.

If diagram abridged sensor detects that in a spinning unit 2, package 45 becomes full volume, then cell controller carries out making the control that the running of spinning apparatus 9 and conveyer stops, and body control setup 30 chassis 4 that carries out making doffing moves to the control of this spinning unit 2.Therewith almost simultaneously, cell controller carries out making the control that reel cage arm 71 rotates to the left side (side, front of wind2 13) of Fig. 2.Thus, coiler drum 74 is left in the package 45 of full volume, and the propulsive effort from coiler drum 74 does not pass to this package 45.In addition, after leaving coiler drum 74, package 45 also carries out inertial rotation.

When the chassis 4 that doffs arrives a spinning unit 2, as shown in Figure 5, doffer 60 rotates counterclockwise by making swivel arm 62, makes package support 65 near package 45.That is, doffer 60 makes package support 65 move to the 1st position P1 from position of readiness P0.

Then, as shown in Figure 6, doffer 60 the 1st position P1 make package support 65 turn to above (conter clockwise) (using the package support 65 shown in long and two-short dash line in figure 6), with the circumferential contact of package 45.Thus, the side face remaining on the package 45 on reel cage 70 is by package support 65 by friction braking, and the inertial rotation of package 45 stops.

Before the inertial rotation of package 45 stops completely, doffer 60 makes reel cage motion arm 89 move to the position shown in Fig. 5.When the rotation of package 45 stops completely, doffer 60 reel cage motion arm 89 makes a coil holder 72 leave other coil holder 72 ground operation reel cage arm 71, takes out the package 45 of full volume from reel cage 70.

Doffer 60 makes package support 65 turn to below (cw).Then, as shown in FIG. 6, doffer 60 makes swivel arm 62 rotate clockwise.In other words, doffer 60 makes package support 65 move to the 2nd position P2.Thus, package 45 is supported by package support 65, and rolls along rake 81, is directed into mounting portion 82.

After package 45 is directed to mounting portion 82, doffer 60 makes swivel arm 62 rotate clockwise further, makes package support 65 move to position of readiness P0.Body control setup 30, when confirming that package support 65 gets back to position of readiness P0, restarts the transporting operation of conveyer.That is, the package 45 moved by mounting portion 82 is transported with conveyer.

Doffer control part 31, when confirming that package support 65 gets back to position of readiness P0, judges on reel cage 70 with or without package 45 according to the testing result of test section 95.Doffer control part 31, when judging reel cage 70 does not have package 45, makes Cylinder feeder mechanism 50 implement bobbin and places action (supply action).

Doffer control part 31 is judging that the supply action that reel cage 70 has the situation Xia Shi Cylinder feeder mechanism 50 of package 45 to carry out controls with stopping (forbidding).Meanwhile, informing portion 96 is informed and is occurred extremely.

As described above, the doffer 60 of the spinning machine 1 of this example possesses when there is obstacle on the reel cage 70 providing bobbin 48, the doffer control part 31 that the supply action of the bobbin 48 that bobbin maintaining part 52 is carried out stops.Doffer control part 31 exists the such as package 45 becoming obstacle on reel cage 70, namely when reel cage 70 is in the state that can not accept bobbin 48, the supply action that bobbin maintaining part 52 is carried out stops.Doffer 60 does not exist obstacle on reel cage 70, namely when reel cage 70 is in the state that can accept bobbin 48, by bobbin maintaining part 52, bobbin 48 is supplied to reel cage 70.Thus, in doffer 60 when bobbin maintaining part 52 carries out the supply action of bobbin 48, can prevent bobbin maintaining part 52 from contacting with package 45.Therefore, the breakage of package 45 and/or the breakage of bobbin maintaining part 52 can be prevented in doffer 60.As a result, doffer 60 can carry out the supply of bobbin 48 well.

The doffer 60 of this example possesses the test section 95 detecting obstacle.According to the testing result of test section 95, doffer control part 31 judges that reel cage 70 has clear.Thus, doffer control part 31 precision can judge that reel cage 70 has clear well, more can carry out the control of bobbin maintaining part 52 by snugly.Therefore, the contact of bobbin maintaining part 52 and package 45 can further be prevented in doffer 60.

The doffer control part 31 of this example, after package support 65 is moved to position of readiness P0 by swivel arm 62 from the 1st position P1, judges that reel cage 70 has clear.Therefore, it is possible to suppress the package 45 be bearing on package support 65 to be mistaken for obstacle.Therefore, the running owing to suppressing the erroneous judgement of doffer control part 31 to cause in doffer 60 stops, therefore, it is possible to suppress the reduction of running efficiency.

The doffer 60 of this example possesses to inform when to there is obstacle on reel cage 70 abnormal informing portion 96 occurs.Thus, this situation of the state of affairs that the supply action of bobbin 48 occurs to carry out can be informed to operating personal etc. by doffer 60.As a result, because resuming operation of carrying out of operating personal is promptly implemented, therefore, it is possible to suppress the decline of running efficiency.
