Definitions

  • My invention relates to a device for increasing the speed of coil replacement in a creel assembly.
  • the threads inserted in the thread tensioners be collected by rows in groups and secured in a thread holder whereby the threads of several, and preferably all, of the vertical rows of the creel assembly are led with the thread holder to the comb of the warper.
  • the insertion of the thread ends into the tensioners calls for a very time-consuming operation whereby the replacement of then unwound supply coils is further delayed due to the requirement of again having to seize the threads which have been inserted in the thread tensioners and securing them in the thread holder.
  • I provide in accordance with my invention a device wherein I dispose at the level of each supply coil of the creel a seizing member located between the vertical rows of tensioning devices and movable therethrough in a direction toward the supply coils for seizing the thread ends which had been suitably placed in readiness or readied at the supply coils for delivering them to the respective tensioners. It is also possible to deliver the threads from the supply coils to the thread tensioners by suitable mechanical or automatic means.
  • I provide a clamping or gripping device to which the seizing member for a vertical row of coils in the creel is rigidly connected.
  • the clamping device be mounted so that it may travel along the creel.
  • the traveling clamping device with a thread holder which can take up .the thread ends that are inserted in the tensioners.
  • the delivery of the threads from the tensioners to the thread holders can thereby be effected either by one servicing operator accompanying the clamping device or also by suitable mechanical means automatically. In the latter case, there would thereby be provided practically a fully automatic creel in relation to the replacement of depleted supply coils.
  • FIG. 1 is a front-elevational view of a creel assembly constructed in accordance with my invention
  • FIG. 2 is a front-elevational view of the right-hand portion of the creel shown in FIG. 1 showing schematically a later phase of the operation thereof;
  • FIG. 3 is a top-elevational view of FIG. 1;
  • FIG. 4 is a top-elevational view of FIG. 2;
  • FIG. 5 is an elevational side view, much enlarged, of a fragment of the creel viewed in the direction of the arrow A in FIG 2;.
  • FIG. 6 is a top plan view of FIG. 5;
  • FIG. 7 is an isolated view of element 15 shown in FIG. 6;
  • FIG. 1 there is shown a creel carriage 1, which travels on wheels 2 and is provided with journal pins 3 for receiving the cross-wound supply coils 4 which are to be unwound.
  • the thread ends thereof are tied together by the individual placing the coils onto the journalling pins, substantially at a location 5 intermediate the uppermost and the lowermost coils of the vertical row of coils in the creel.
  • the thread ends of the cross-wound coils are hereby readied and, in fact, in the illustrated case of FIG. 1, in such a manner that they can be clamped between the bristles of a brush 3a located in front of the journalling pin 3.
  • FIG. 1 There is further schematically shown in FIG. 1 a support post 6 on which the individual thread tensioners 7 are secured. Seizing members, which will be described more fully hereinafter, represented by the dot-dash lines 8, are insertable between the adjacent supporting posts 6. When the seizing members 8 are withdrawn, they transfer he threads to the respective tensioners 7 so that after the hreads are collected, the positions indicated by the dotand-dash lines '9 are attained by the threads.
  • Seizing members which will be described more fully hereinafter, represented by the dot-dash lines 8 are insertable between the adjacent supporting posts 6. When the seizing members 8 are withdrawn, they transfer he threads to the respective tensioners 7 so that after the hreads are collected, the positions indicated by the dotand-dash lines '9 are attained by the threads.
  • the supply coils 4 on the pins 3 with the brushes 3a, as well as the tensioners 7, can be readily recognized.
  • a seizing member 10 whose original position is shown in phantom, the seizing members being insertable between two vertical rows of tensioners in a path corresponding to the dot-dash line 11.
  • the seizing member seizes with its forward barbed hook 10a the thread end previously readied on the cross-wound coil 4.
  • the thread end, in the solid line position of the seizing member 10 is drawn oif the coil 4 and transferred to the respective tensioner 7.
  • the seizing member 10 then returns preferably in the same way to the dot-dash or phantom original position thereof.
  • FIG. 2 It can be seen from FIG. 2 how the thread ends can be drawn or guided into the vicinity of the tensioner 7 by the seizing member.
  • the threads of a vertical row of coils in a creel are drawn from the tensioning zone in accordance with the dotted lines 12 so that the connecting point or intersection point 5 of all the threads is clamped in the thread holder 13.
  • FIG. 4 In the top-elevational view of FIG. 4 there are shown the thread lengths F and P of the vertical coil rows of the creel that are farthest away from the warper (not shown) which have already been inserted in the comb 13 so that the seizing member can seize the threads of the next vertical coil rows of the creel corresponding to the dot-dash or phantom line 14.
  • FIGS. 5 and 6 there is shown how the threads can be drawn from the cross-wound coil 4 and supplied to the tensioner. Besides the supply coils 4 seated on the pins 3, one can see the supporting post 6 for the thread tensioners 7 which, in this case, have the form of double disc tensioners. These disc tensioners are provided with insertion contours 15 which take up the threads at the end of the movement of the seizing member 10 as indicated by the dot-dash line 11 (FIG. 6). The seizing member is then returned in the same way along the dot-dash line 11. In the interest of affording a better view thereof, the thread tensioner 7 with the insertion contour 15 is shown in isolation in FIG. 7. It is also noted from FIG.
  • the seizing members 10 do not have to be moved implicity according to the dot-dash line 11 (FIG. 3), but such movement can be achieved with particularly simple means as shown for example in FIG. 8.
  • a frictionless plural-linkage transmission system is illustrated in FIG. 8, which has proven to be particularly suitable for driving the seizing member 10.
  • the holder arm 17 of the seizing member 10 is connected articulately with control rods 18 and 19 at the locations 17a and 17b.
  • the control rods 18 and 19 are connected at the joints 20 and 21 respectively wtih the fixedly mounted pivots 22 and 23 and at the joints 24 and 25 respectively with the fixedly mounted crank drives 26 and 27.
  • the seizing member first places the thread at the insertion contour 15 for the tensioner 7.
  • a thread path along the dot-dash line 1511 from the insertion contour 15 to the non-illustrated thread holder (but see FIG. 9) may then result. If the thread holder 13 then moves in a direction toward the beam warper, e.g. in the direction of the arrow in FIG. 5, the pull exerted on the thread then acts to insert the thread along the insertion contour 15 of the tensioner into the tensioner '7 whereby a thread path corresponding to the dot-dash line 7 a is produced.
  • the carriage 29 is provided both with the thread holder for taking up the thread ends inserted into the tensioners, as well as with the drive for the entire gripping device.
  • This drive can be of the type illustrated in FIG. 8.
  • the joints 17a and 17b for the device of FIG. 8 are then correspondingly mounted on the bar 28.
  • the carriage 29 can be provided additionally with an arresting or braking device 30 which ensures that the carriage will always stop at the desired gripper location in front of a vertical coil row of the creel.
  • the gripping device 10, 16, 28 first draws oh the threads of the coil row of the creel which is farthest from the warper. Then, the carriage 29 travels farther in the direction of the warper for a creel division so that the gripping device, operating stepwise, fishes out the readied thread ends of the full cross-wound coils 4 stuck on the lattice-like frame 1 and inserts them in the zone of the thread tensioner. From there, the thread ends are clamped in the common thread holder 13 along the dot-dash line provided with an arrow 31 and travel together in a direction toward the warper. The insertion of the threads in the common thread holder 13 can be efiected either by hand or by a mechanical gripping device.
  • the entire device can be more or less fully mechanized.
  • the seizing member located at the level of each supply coil of the creel lattice and movable between the vertical tensioner rows in a direction toward the supply coils for seizing the thread ends readied at the supply coils and transferring them to the appertaining tensioners, it has become possible for the first time to considerably increase the speed with which the coils of the creel are replaced and especially the speed with which the threads are inserted in the tensioners.
  • the invention of this application permits, both by manual servicing or fully automatically, to draw off the threads from the coils, insert them into the tensioners and finally clamp them in the common thread holder, an interval of about 3 to 4 seconds per coil row of creel lattice being required for this entire operation with manual servicing. This period can be even further reduced with skilled and well-familiarized servicing personnel, as well as when the device is made fully automatic.
  • a creel assembly including a multilevel creel for supply coils having readied thread ends, the coils being arranged in substantially vertical rows, and tensioning devices also arranged in substantially vertical rows spaced from the creel and adapted to be located intermediate the creel and a warper for performing warper operation on the thread from the supply coils, the improvement comprising a seizing member disposed at each level of the supply coils mounted on the creel and located between the vertical rows of tensioning devices, said seizing member being movable between said vertical rows of tensioning devices in a direction toward the supply coils for seizing r' if!) the readied thread ends thereof and delivering them to for taking up the thread ends inserted in the tensioning the respective tensioning devices. device.
