The present invention relates to a kind of by claim 1 device for storing and provide bobbin as described in the preamble.

Background technology

When making and process synthetic filaments, usually when technological process or subprocess ending, winding filament is become reel.For this reason with winding filament on the perimembranous of the bobbin that keeps by a reel stand.At this moment, bobbin can directly drive by reel stand or by the driven roller that sets to reel stand, with winding filaments.At this, after the reel coiling is complete, usually carry out changing bobbins on reel stand.This need to expend a large amount of hand labours, wherein at first full reel will be taken off from winding head, then will provide the bobbin of a new sky to reel stand.In order as far as possible hand labour to be minimized, more known automatic lifting at least basically is for the device of bare bobbin.

For example by the known a kind of such device of WO2007/101649A1, this known devices has be used to the storage path that stores a large amount of bobbins, and bobbin remains in described storage path as bobbin heap.Be provided with a delivery port storing the end, path, connecting a guide pipe that is vertically oriented on this delivery port.By a dosing mechanism that acts on the bobbin heap, realized the control that bobbin is exported from the selectivity that stores the path via delivery port and guide pipe.In order to receive the bobbin of derivation, the free end of guide pipe is equipped with one and receives mandrel, and this reception mandrel is accepted bobbin.Receive mandrel and do to such an extent that can swing, and bobbin can be directed to the winding head of winding mechanism after accepting bobbin.

In this known devices, in order to export bobbin, whole bobbin piles up to store in the path and moves to delivery port along the bottom.Be formed on the delivery port that stores in the bottom, path and cause having such danger when the movement of bobbin heap is increasing, last the bobbin overturning that namely stores in the path is also stuck in storing the path.In addition, store the path at run duration and can not be added charging.

Summary of the invention

Therefore the objective of the invention is, improve like this device that is used for storing and providing bobbin of described type, make and to carry out reliably optionally guiding and the output of bobbin.

According to the present invention, this purpose realizes by such method, namely stores the path and is vertically oriented together with the bobbin heap, and be equipped with a bobbin slideway with respect to the plumb bob vertical inclination to delivery port outside storing the path.

The present invention is not similar to the known devices of JP 51-011938, and a large amount of bobbins up and down remains in a storage path that is vertically oriented stackedly in this known devices.Be formed with a delivery port storing the end, path, this delivery port and a certain amount of feeder combined action are to export the bobbin of a storage.Be provided with one can pass through the maintained capture dish of mode of an actuator parallel motion from storing a distance, path below delivery port, the capture dish can capture position and one by actuator and deliver between the position and move back and forth, the bobbin of exporting from store the path in delivering the position is introduced to a gripping arm, and the winding head of winding mechanism is inputted bobbin in this gripping arm.This known devices needs large cost of equipment so that the bobbin that will export from store the path is transported to winding head, due to for delivery of bobbin to deliver position quantity many, estimate that out of order possibility is larger in this known devices.

On the contrary, the present invention can take out and deliver bobbin from storing the path reliably in the situation that mechanism is delivered in the centre that need not add.At this, bobbin automatically is directed on the free end that receives mandrel from delivery port and bobbin slideway after being discharged by a certain amount of feeder.The bobbin slideway that tilts has been realized the directed and location of bobbin, therefore bobbin directly can be directed in bobbin slideway end to receive on mandrel.

For bobbin is skidded off on the bobbin slideway with finding no fault with, the bobbin slideway with respect to plumb bob vertical have one from 10 ° to 75 ° the degree of dip in scope.

In order optionally to take out bobbin from store the path, the such improvement structure of the present invention is advantageous particularly, dosing mechanism mutually leaves by two the locking rods that certain distance arranges and forms in this improvement structure, wherein said locking rod can be used for one by independent actuator bottling up in storing the path/and the lock position and of stop bobbin is used for unclamping between the releasing position of bobbin and moves, and therefore can optionally take out one or more bobbins from store the path.At this, upper locking rod is used in storing the path fixedly bobbin heap, and lower locking rod can activated in order to quantitative output bobbin.

In order particularly to discharge the most next bobbin of bobbin heap from store the path, the preferred such improvement structure of the present invention of implementing, improve in structure at this, distance in storing the path between locking rod and lower locking rod is substantially equal to the diameter of bobbin, and actuator can be by a control mechanism alternately by starting/activation.Therefore between the most next bobbin period of output, the bobbin heap can remain on regularly and store in the path.Only after the most next bobbin shifts out, just carry out the follow-up of bobbin heap from store the path.

A taking-up from store the path in bobbin preferably utilizes a contact pickup to carry out, and this contact pickup detects the position of the reception mandrel on the outlet side that stores the path.Therefore arrive when accepting the position and can start dosing mechanism by control mechanism receiving mandrel, only make to be retained in it and to accept and just take out bobbin in locational situation receiving mandrel.

In a kind of particularly advantageous improvement structure of the present invention, form in the open cross-section of the delivery port that stores the end, path by a rectangle, the opening of this open cross-section is shorter in length than length of bobbin, and the A/F of this open cross-section is greater than bobbin diameter.Therefore just can at bobbin produce a pre-tilt out the time at bobbin from store the path, this pre-tilt makes and can mildly slip in the bobbin slideway.At this, the opening length of the open cross-section of delivery port has determined that basically bobbin is at the inclination angle out time the from store the path.

Therefore for bobbin is skidded off under heeling condition automatically at equipped at outlet port, the opening length of delivery port open cross-section is longer than half of length of bobbin, and only the gravity by bobbin just can produce overturn moment on bobbin.

But this overturn moment on bobbin also can produce by lower locking rod, and this time locking rod is formed by two piston rods of separately controllable piston cylinder unit.

Take out second bobbin from store path 1 before, at first play acting actuator 11.1, in order to make locking rod 9 move to as shown in Figure 2 lock position from its releasing position.Can restart now to implement to discharge the most whole process of next bobbin.

In order to monitor bobbin in the reception that receives on mandrel 14, equally also there is such possibility, namely be provided with contact pickup on reception mandrel 14, this contact pickup for example starts one and is used for making the swing actuator that receives mandrel 14 swings.

Also have such possibility under situation as shown in Figure 2, namely

locking rod

9 and 10 is made, and makes bobbin heap 19 be stretched over nethermost bobbin 18 always.In this case, locking rod 9 only stretches into that to store path 1 so dark, makes between the most next bobbin and penultimate bobbin 18 and can contact.Preferably leave a little gap between the free end of locking rod 9 and penultimate bobbin 18, make whole bobbin heap 19 keep by lower locking rod 10.By this project organization, advantageously support the output of the most next bobbin after locking rod 10 discharges.But bobbin heap 19 can only be advanced to across with the gap of locking rod 9 till.

In the embodiment as depicted in figs. 1 and 2 of apparatus of the present invention,

locking rod

9 and 10 actuators 11.1 and 11.2 by electricity activate.But also can adopt in principle air cylinder to make this locking rod move on to two positions.At a kind of possible embodiment of locking rod shown in Fig. 6 and Fig. 7, wherein Fig. 6 illustrates locking rod and is in lock position, and locking rod shown in Figure 7 is in the releasing position.Here can both relate to lower locking rod 10 and also relate to locking rod 9.Two

locking rods

9 and 10 can be designed to same structure in principle.In this example, two piston cylinder unit 28.1 and 28.2 are arranged side by side on the sidewall 5.2 that stores path 1.Piston rod 27.1 and 27.2 28.1 and 28.2 is interiorly loaded by spring 29.1 and 29.2 respectively like this in the piston cylinder unit, makes the free end of piston rod 27.1 and 27.2 remain on a lock position in storing path 1.This situation shown in Figure 6.

In order to unclamp the most next bobbin 18 or the bobbin heap 19 that stores in path 1, co-controlling piston cylinder unit 28.1 and 28.2, thus its releasing position is return and occupied to the spring force that makes piston rod 27.1 and 27.2 overcome spring 29.1 and 29.2.Figure 7 illustrates this situation.

For lower locking rod 10, also can be in short time power piston cylinder unit 28.1 and 28.2 successively, make bobbin fall down with an attitude that tilts with respect to the bottom 6 that stores path 1.

Locking rod 9 as shown in Figure 6 and Figure 7 and 10 actuating device also can alternatively be formed by the two-way ram cylinder unit.

Therefore the salient point of apparatus of the present invention particularly in, can be in the situation that need not manually support bobbin is flowed to the winding head of wind2, to reach increasingly automated.Therefore the additional charge that preferably only stores the path just manually carries out.
