Definitions

  • ABSTRACT A device for feeding empty bobbins to a conveyor car- [52] rying hooks for gripping the bobbins, has means for 51 I Cl 6 47 52 orienting the empty bobbins for gripping by the conq 5 57/53 veyor hooks and an element tiltable between a posi- 1 0 l tion to receive an oriented bobbin and a position to References Cited present same to a hook.
  • the present invention relates to feeding devices for empty bobbins; and, more'particularly, to such devices useful in automatic bobbin changing apparatus for replacing the bobbins in textile machines with spindle ranges, such as continuous spinning frames.
  • Automatic bobbin changing apparatus of the class described comprise an endless conveyor belt supported by means arranged along each spindle range, the conveyor carrying gripping hooks spaced atregular distances corresponding to the distances between the spindles of the spindle range, each gripping hook being equipped for cooperating with a gripping head provided at the upper end of each bobbin; and a loading station is equipped so that the gripping head of an empty bobbin is presented to each gripping hook pass-' ing at its level.
  • the loading station must be supplied with empty bobbins during the entire duration of the operation of loading one section of the endless conveyor with empty bobbins.
  • the present invention is concerned with a feeding device .especially adapted to an automatic bobbin changing apparatus with an endless conveyor and bobbin gripping hooks, and contributes a feeding device which reduces to a minimum the swinging tendency of the empty bobbins after gripping.
  • the feeding device comprises means for setting'the bobbins upright so that the empty bobbins are fed with their gripping heads directed upwardly, and is characterized in that a tiltable element mounted on a swivelling shaft is provided which, under the effect of a drive mechanism, can take a receiving position in which an empty bobbin is delivered by the means for setting the bobbins upright, as well as a presenting position in which the empty bobbin is presented sothat its gripping head is in the path of the gripping hooks.
  • the pivoting shaft of the tiltable element so that it is urged upwardly by elastic traction means
  • the tiltable element comprises a stop element cooperating with a fixed ramp oriented to oppose the action of these elastic traction means until the tiltable element has nearly reached its presenting'position and is liberated from the fixed ramp after this position has been exceeded so that the tiltable element rises under the action of the elastic traction means which urge the pivoting axis upwards.
  • the tiltable element feeds the empty bobbin to a position in which it is stopped by the support of the endless conveyor.
  • FIG. 1 is an elevational view of the feeding device
  • FIGS. 2, 3 and 4 are views illustrating three different positions of the tiltable element shown in H6. 1.
  • FIG. 1 part of the automatic bobbin changing apparatus l is shown, and this apparatus comprises an endless conveyor 2 which is carried by a support and is placed along each spindle range (not shown), the endless conveyor 2 carrying gripping hooks 4 at regular distances corresponding to-the distances between the spindles of the spindle range.
  • Each gripping hook 4 is able to cooperate with a gripping head 5 provided at the upper end of each empty bobbin 6.
  • a loading station equipped so that a gripping head 5 of an empty bobbin 6 is presented to each gripping hook 4 passing on its level.
  • This loading station is fed with empty bobbins 6 by a feeding device comprising a reserve container 7 in which the empty bobbins 6 are stored in horizontal position, without any discrimination of the side on which the gripping head 5 is situated, and means 8 for setting the bobbins upright so that their gripping heads 5 are situated upwardly of the bobbins.
  • the means 8 for setting the bobbins upright may comprise two stop elements 9 and 10 by which an empty bobbin 6 is temporarily retained by its gripping head 5.
  • Each empty bobbin 6 arriving at the level of the means 8 for setting the bobbins upright is temporarily retained by its gripping head 5 cooperating with one or the other of the stop elements 9 or 10, depending on the way in which the empty bobbin 6 is presented, and this bobbin then effects, under the influence of gravity, a pivoting movement about its gripping head, and, finally, all bobbins leave the means 8 for setting the bobbins upright in oriented condition so that their gripping heads 5 are directed upwardly.
  • the means 8 for setting the bobbins upright are advantageously provided in the upper part of the reserve container 7, and the empty bobbins 6 are fed to the said means 8 by a cup elevator 11, the rising section of which constitutes a lateral part of the reserve container 7, the cup elevator 11 being driven by motor 12, as will later be explained in more detail.
  • the bobbins fall into an inclined channel 13 in which they are transported by gravity.
  • the feeding device comprises bobbin carrying means in the form of a tiltable element 14 which is mounted on a pivot shaft 15 and which can take, under the action of a moving mechanism, a receiving position in which the tiltable element 14 can receive an empty bobbin 6 delivered by the means 8 for setting the bobbins upright, the receiving position being such that the tiltable element 14 forms then an extension of the channel 13 (FIGS. 1 and 2); and a presenting position in which the tiltable element 14 presents the empty bobbin 6 so that its gripping head is in the path of the gripping hooks 4 (FIG. 4).
  • the pivoting shaft 15 of the tiltable element 14 is urged upwardly by means of elastic traction means 17, and the tiltable element 14 comprises a stop element 18 cooperating with a fixed ramp l9 oriented to oppose the action of these elastic traction means 17 until a position of the tiltable element 14 very near to its presenting position is reached.
  • the topping element 18 is thereupon liberated from the fixed ramp 19 beyond this position so that the tiltable element 14 rises again under the action of the elastic traction means 17 which urge the pivoting shaft 15 upwardly. Under these conditions, and when the tiltable element 14 reaches its presenting position, it leads the empty bobbin 6 towards the stop formed by the support 3 of the endless conveyor 2 which, at this location, presents a support surface 3a.
  • the pivoting shaft 15 can be carried by one link or arm 20a of a bellcrank lever 20 having two links or arms, the lever being mounted in its center on a fixed pivot 21 and the other arm 20b of which is urged downwardly by the elastic traction means 17, which are advantageously constituted by a blade spring fixed at one end on this arm 20b, and abutting at its other end against a pin 22.
  • the driving mechanism 16, which actuates the tiltable element 14, can be constituted by a pneumatic double-action ram the body 23 of which is pivotally connected to a fixed part of the device and the piston rod 24 of which is pivoted to the tiltable element 14 by means of a cap 25. It is this cap which carries the stop element 18 which in turn may comprise a roller mounted free for rotation on the said cap.
  • this channel is equipped, towards its lower end, with a retaining pin 27 carried by a pivoting lever 28 and normally urged by a spring 29 to protrude into the channel 13 to retain the empty bobbin 6.
  • the tiltable element 14 is equipped with a projection 14a to exert pressure on the pivoting lever 28 when the element 14 is in receiving position so that the retaining pin 27 is retracted.
  • This device 30 may advantageously consist of a pneumatic double-action ram, the body 31 of which is fixed on the tiltable element 14 and the intermediate shaft 32 of which constitutes the member which retains the empty bobbin 6 within the tiltable element 14. As shown in FIG. 2, the device 30 is mounted on the tiltable element 14 with a blade spring 26 which elastically maintains the empty bobbin within the said tiltable element.
  • the endless conveyor 2 is driven by a drive motor (not shown) carried by the bobbin changing apparatus 1, the output shaft of the motor driving the endless conveyor via a cog-wheel transmission 33.
  • This driving may be effected at a speed of the order of 13 meters per minute, for example, and is adapted to the various operatory phases of the automatic bobbin changing apparatus 1; however, this speed is too high for the operatory phase consisting in loading the section of the endless conveyor 2 with empty bobbins 6.
  • the speed of the endless conveyor 2 should be approximately l meter per minute, i.e. 13 times slower than its normal speed, for loading.
  • the cog-wheel transmission 33 of the bobbin changing apparatus 1 furthermore comprises a coupling ferrule 35 for cooperating with a coupling ferrule 36 supported by the output shaft of the auxiliary motor 34.
  • a coupling ferrule 35 for cooperating with a coupling ferrule 36 supported by the output shaft of the auxiliary motor 34.
  • One and/or the other of these two coupling ferrules 35, 36 is flexible for compensating the height variations of the bobbin changing apparatus 1 around its feeding position.
  • These two coupling ferrules 35 and 36 are connected by relative displacement, for example by displacing the coupling ferrule 35 under the action of a pneumatic screwjack or ram coaxial with the coupling of ferrule 36.
  • the function of the described feeding device is then effected by a pneumatic distributor 37 (H6. 1) which is fed by a compressed air source 38, and controlled by a detector 39, for example, of the electromagnetic type which delivers a signal during the passage of a gripping hook 4 at its level.
  • a pneumatic distributor 37 H6. 1
  • a detector 39 for example, of the electromagnetic type which delivers a signal during the passage of a gripping hook 4 at its level.
  • the pneumatic distributor 37 is then acted upon to feed the ram of the motor mechanism 16 so that the tiltable element 14 ismoved from its receiving position into its presenting position, and to feed the ram of the device so that it maintains the empty bobbin 6 within the element 14.
  • the pneumatic distributor 37 feeds the screw-jack or ram of the coupling ferrule 36 and, on the other hand, controls the activation of the motor 12 of the cup elevator 11 so that the said motor drives the cup elevator by one step," i.e.-by a distance separating two successive cups.
  • the motor 12 may be constituted by a doubleaction pneumatic ram 39 actuating a ratchet-wheel 40.
  • This action of the pneumatic distributor 37 thus causes, on one hand, the coupling of the two coupling ferrules and 36, and the driving of the endless conveyor 2 at its loading speed and, on the other hand, the arrival of an empty bobbin 6 in the channel 13 where it is stopped by the retaining pin 27 (FIGS. 3 and 4).
  • the same delivers a signal which inverts the pneumatic distributor which simultaneously causes the feeding of the ram of the motor mechanism 16 so that the tiltable element 14 is moved from its presenting position in to receiving position, the feeding of the screwjack or ram ofthe device 30 which frees the empty bobbin 6 and', finally, the feeding the ram of motor 12 which reloads the ratchet-wheel 40.
  • the coupling ferrules 35 and 36 remain in coupled position.
  • the tiltable element 14 after regaining its receiving position, depresses the retaining pin 27 which frees the empty bobbin next ready for delivery in the channel 13, that empty bobbin being thereby placed in the tiltable element 14.
  • the pneumatic distributor 37 simultaneously causes the feeding of the ram of the motor mechanism 16 so that the tiltable element 14 is moved from its receiving position into its presenting position, the feeding of the screw-jack or ram of device 30 which maintains the empty bobbin 6 in the tiltable element 14 and, finally, the feeding of the ram of motor 12 which advances the ratchet-wheel 40 by one step and thus feeds a new empty bobbin 6 to the channel 13 where it is stopped by the retaining pin 27.
  • detection means 41 can be provided which are equipped so that, on one hand, they assure that an empty bobbin 6 is ready in the channel 13 and, on the 6 other hand, that there is only one empty bobbin in the said channel.
  • two sensitive elements with photoelectric cells can be disposed on either side of the-channel l3, i.e. a lower sensitive element for detecting the presence of an empty bobbin 6 ready for delivery and an upper sensitive element 43 for detecting the absence ofa second empty bobbin above the empty bobbin 6 ready for delivery.
