The specific embodiment
Fig. 1 representes to have summary shifting apparatus, conveying device of roller body of the present invention that is used to receive the former feed roller of being controlled by a pair of holding device and constitutes, and Fig. 2 is through the formation of the control system of block representation shifting apparatus shown in Figure 1.
The summary of in Fig. 1, only representing the shifting apparatus 10 of conveying device of roller body constitutes.The handing-over place in order to transmit former feed roller 100 to its 2 holding devices of controlling; Can be with identical at device illustrated in fig. 7; So detailed; But in order distinguishing, to give reference number 72-1, to give reference number 72-2 the holding device on right side among the figure to the holding device in left side among the figure.And shifting apparatus 10 is equipped in the portion of going with drive wheel, flower wheel usually, but this portion of going is not a content of the present invention, therefore omits its diagram, explanation.
Shifting apparatus 10 has 2 core support 11-1,11-2,2 core support 11-1,11-2 separately can be through being provided with respectively elevator 12-1,12-2 and go up and down respectively.Though omit diagram, core support 11-1,11-2 separately for the barrel-contoured core 110 of supporting easily, the upper surface forms V word shape or circular-arc.Last at 2 core support 11-1,11-2, as the unit that the power (perhaps load) that is applied to it is detected, and be provided with force transducer 13-1,13-2.
Below, in order to distinguish 2 elevators and 2 force transducers shown in Figure 1, left side among the figure is called elevator (left side), force transducer (left side), right side among the figure is called elevator (right side), force transducer (right side).
In Fig. 2, controller 20 has acceptance from the detection signal of 2 force transducer 13-1,13-2 and control the function of 2 elevator 12-1,12-2 respectively.The control action of first, second mode of explanation after controller 20 is carried out based on control program, this control program is made in advance and is stored in the built-in memory storage.Sort controller 20 also can be realized through index drum body carrying device single-piece main control unit (omitting diagram).
Controller 20 is known or unknown according to the weight of former feed roller 100, carries out control action through following 2 kinds of modes.
(first mode)
< weight of former feed roller is the situation of given value W >
The weight W of the former feed roller 100 that at this moment, 20 inputs should receive to controller.
Fig. 3 representes the flow process based on the control action of the elevator of controller 20 (left side) 12-1, but also identical for elevator (right side) 12-2, carries out control concurrently.
(1) core support 11-1,11-2 are risen, up to the value that is detected by each force transducer 13-1,13-2, be that load F becomes W/2 (step S1), (elevator drives control: step S2, S3) stops to rise if load F surpasses W/2.
(2) if put on load F (left side), the load F (right side) of each force transducer 13-1,13-2; Being in value W/2 respectively is basis and in the allowed band confirmed in addition (step S4, S5); If then making elevator (left side) 12-1, elevator (right side) 12-2 is halted state (step S6) in its position; And load F (left side), load F (right side) both sides have been confirmed above-mentioned point (step S7), then holding device 72-1,72-2 are extracted from core 110.That is, under the situation of W/2-ε＜F (left side)＜W/2+ ε and W/2-ε＜F (right side)＜W/2+ ε, extract holding device 72-1,72-2.In addition; Because the control system of holding device 72-1,72-2 is respectively independently; Therefore, then produce the signal that the control system indication of holding device 72-1,72-2 is extracted, and send it to above-mentioned control system through wireless etc. if controller 20 has been confirmed above-mentioned point.Thus, in holding device 72-1,72-2, carry out extracting of handle part.
In addition; At step S4; Under the situation that does not satisfy F (left side)＞W/2-ε, the load that acts on the core support 11-1 in left side is less, and maybe and the core support 11-2 on right side between produce overbalance; Therefore return step S1 and the core support 11-1 in left side is risen, carry out above-mentioned control action later on.
On the other hand; In step S5, under the situation that does not satisfy F (left side)＜W/2+ ε, the load on the core support 11-1 on the left of acting on is excessive; And maybe and the core support 11-2 on right side between produce overbalance, therefore transfer to step S8 and the core support 11-1 in left side descended.Repeat this action till satisfying F (left side)＜W/2 (step S9), if satisfy then return step S3 and the later step of execution in step S3.
Through core support (right side) 11-2 also being carried out the control action of above that kind; Can make the load that acts on core support (left side) 11-1, core support (right side) 11-2 from former feed roller 100; In the allowed band of (W/2-ε)～(W/2+ ε), keep balance; Can make extracting of holding device 72-1,72-2 smooth and easy, thereby carry out the reception of former feed roller 100 swimmingly.
In addition,, can shorten the period, but also can carry out unilaterally at every turn through carrying out the drive controlling of core support (left side) 11-1 and core support (right side) 11-2 concurrently.And; Use the combination of door shape arm and holding device as the unit of holding core 110; But this only is an example, for a pair of holding device arranged opposite also can be adopted arbitrary structures, keeps former feed roller 100 as long as can utilize the protrusion of core 110; Can adopt any holding unit, be not limited to holding device.These after the explanation second mode in also be identical.
(second mode)
< the weight condition of unknown of former feed roller >
The relation of core support 11-1 that Fig. 4 supports with the protrusion of the core 110 in the left side of former feed roller 100, to this protrusion and the holding device 72-1 that controls is amplified expression.
And, the height and position y of the core support when Fig. 5 is illustrated in the control action of the present invention's second mode and the variation in time that acts on the load F of force transducer, Fig. 6 representes the flow process of the control action of second mode.
Being characterized as of second mode; Under the situation of not relevant information with the weight of former feed roller 100; Controller 20 is carried out control actions, so that core support 11-1, the 11-2 of the load (approaching the value of W/2) that matches with the weight of former feed roller 100 about putting on respectively.Gap e between the peripheral part of the internal diameter of the protrusion through utilizing core 110 and holding device 72-1,72-2 realizes this characteristic.That is, enter into for the holding part that makes holding device 72-1,72-2 in the protrusion of core 110 and control, need make the internal diameter of the external diameter of handle part less than the protrusion of core 110.At this moment, the downside of the handle part of holding device 72-1, and the downside aperture surface of the protrusion of controlling by handle part between, as shown in Figure 4ly can form gap e.
This gap significantly occurs when adopting the holding unit of air spider that kind especially.That is, air spider imports pressurized air and presses to the expansion of external diameter direction through its air to handle part making after its handle part enters in the protrusion of core 110, makes the aperture surface closed contact of the protrusion of itself and core 110 thus.Therefore, air presses 0 handle part in the protrusion of core 110, and is as shown in Figure 4, can be between the downside aperture surface of the downside of handle part and protrusion formation gap e.But its prerequisite is the end that does not act on core 10 from the side pressure of holding device 72-1.So-called side pressure is meant, on the end that the part of holding device is pressed into core 110 through pressurized air etc. and applied pressure.
As stated, be following 2 points for the precondition of implementing second mode.
1, before core support 11-1,11-2 were risen, the downside that is in the handle part of the protrusion that enters into core 110 was guaranteed the state of gapped e.
2, the side pressure from holding device does not act on the core 110.
More than 2 mean, core 110 do not receive from miscellaneous part power, by the handle part support, be in so-called suspended state.And, as stated, can through the air that uses air spider and when the reception of shifting apparatus, discharge handle part press and release action in the side pressure of core 110, realize above this 2 point.
With reference to Fig. 4～Fig. 6, the control action of controller 20 is described according to second mode.In addition, use air spider, but so long as guarantee the holding unit of gapped e also to be not limited to holding device at the downside of the handle part of the protrusion that enters into core 110 as holding device.
Situation about in Fig. 5, representing does; At the height and position of establishing the handle part downside when being in gripping state is the wall thickness of Hc, core 110 when being C, the upper end of core support 11-1 along with its rising with the downside of the protrusion of core 110 outside the height and position y of diametric plane when contacting represent by (Hc-e-C).Load this moment begins to act on force transducer 13-1.Afterwards, will rise in the upper end of core support 11-1, but can form the indeclinable interval of height and position y through the bending of machinery.The bending of so-called machinery is meant, shifting apparatus, elevator, the bending of core support single-piece.That is, each several part is crooked when elevator is risen, and does not rise up to (till the amount of bow that the weight that arrives with former feed roller matches) core till the weight of the former feed roller of core support part supports.But the load that acts on force transducer 13-1 continues to rise.When the rising halted state based on the bending of machinery disappeared, the upper end of core support 11-1 began to rise once more, with core 110, be that former feed roller 100 rises to the height and position by (Hc-C) expression.During this period, act on the power of force transducer 13-1, owing to causing, do not have other power, so load is constant except load by former feed roller 100.Especially, if move similarly in core support 11-2 side, then when the weight of the former feed roller 100 of hypothesis was W, the load that acts on core support 11-1,11-2 was about W/2.When the height and position y of core support 11-1 upper end reaches (Hc-C); Because the downside aperture surface of the protrusion of core 110 becomes the state of the downside of the maintaining part that is pressed against holding device 72-1 afterwards; Though therefore need only the indication of elevator 12-1 being given rising; The load that then acts on force transducer 13-1 just continues to increase, but the height and position y of core support 11-1 upper end does not change.
The variation figure of controller 20 detected value of such force transducer 13-1 more than keep watch on is controlled the up-down of elevator 12-1,12-2, and can make act on core support (left side) 11-1, core support (right side) 11-2, be about W/2 from the load balance of former feed roller 100.
Followingly this control action is described with reference to Fig. 6.Fig. 6 mainly representes the flow process of the control action of 20 pairs of elevators of controller (left side) 12-1, but also identical for elevator (right side) 12-2, carries out control concurrently.
In Fig. 6, with in the protrusion that gets into core 110 and the air of handle part of controlling the holding device 72-1 of core 110 press and end, promptly be 0, and the side pressure that also will act on core 110 is by (step S10).This is through before the reception action of the former feed roller 100 of controller 20 beginning, carry out through the control system that this order is sent to holding device 72-1,72-2 such as wireless.Under this state, as stated, core 110 becomes the state on the maintaining part that is suspended in air spider.
Afterwards, play elevator 12-1 and core support 11-1 is risen, and carry out the judgement action (step S11) whether the detected value of force transducer 13-1 changes.This interval is the action till diametric plane contacts outside core support 11-1 begins to rise to the downside with the protrusion of core 110, corresponding to the STEP11 of Fig. 5.
Because core support 11-1 contact with core 110, and during the detected value of force transducer 13-1 appearance variation, transfer to step S12.In step S12, carry out the judgement the action whether variation of the detected value of force transducer 13-1 stops.In step S12, the load that puts on force transducer 13-1 is risen, but the height and position of core support 11-1 does not change owing to bending.This interval is corresponding to the STEP12 of Fig. 5.
When the rising based on bending stopped to disappear, the variation of the detected value of force transducer 13-1 stopped, and when being judged as this situation through controller 20, transferred to step S13.The rising of elevator 12-1 stops in step S13.This interval is in following state corresponding to the STEP13 of Fig. 5: core 110 is supported by core support 11-1, and is had the gap of not enough gap e between the downside aperture surface of the protrusion of the downside of the handle part of holding device 72-1 and core 110.Whether the core support 11-2 side of carrying out the opposing party at step S14 also becomes the judgement action of this state; If the core support of confirming as two sides has all become above-mentioned state; Then produce the signal that handle part is extracted in to the control system of holding device 72-1,72-2 indication, and this signal is sent to above-mentioned control system through wireless etc.Thus, carry out extracting of handle part at holding device 72-1,72-2.
Through the elevator 12-1 of above that kind, the control action of 12-2; Can make act on core support (left side) 11-1, core support (right side) 11-2, be about W/2 from the load balance of former feed roller 100; And can carry out extracting of holding device 72-1,72-2 swimmingly, thereby carry out the reception of former feed roller 100 swimmingly.
In addition, main contents of the present invention are the reception action of former feed roller, so first, second mode has all been explained the control action when being in former feed roller 100 by a pair of holding device hold mode and receiving.To this; Will put in the former feed roller 100 of 2 core support 11-1,11-2 be delivered to its holding unit, for example under the situation of a pair of holding device; Control elevator 12-1,12-2 and former feed roller 100 is orientated as, the protrusion of the core 110 of its both sides is mutually opposed with the handle part of a pair of holding device, if this release; Then carry out following control action: the control system to holding device is sent indication, handle part is got in the protrusion of core 110 and controls core 110.Location for above-mentioned has proposed the whole bag of tricks, adopts which kind of method can.
