United States Patent T 31,6 0 Int. Cl. B23p 19/04; B23q 7/10 US. Cl. 29211 6 Claims ABSTRACT OF THE DISCLOSURE An apparatus for ejection and insertion of a warp cheese carrier into the axial opening of yarn spools or the like, which comprises a machine frame and a supporting table for yarn spools mounted in the machine frame. The supporting table has passage openings of about the largest diameter of a warp cheese carrier. A magazine carrying warp cheese carriers to be inserted is provided and a double-transport shed is movably disposed below one of the passage openings of the supporting table. The doubletransport shed has two halves, and one of the halves is adapted to receive from above the ejected one of the warp cheese carriers and the other of the halves enters a position below the passage opening after the ejection of the warp cheese carrier. The other of the halves of the double-transport shed comprises a catching mouth receiving the warp cheese carrier to be inserted and pointing to the magazine.

The present invention relates to an apparatus for ejection and insertion of a warp cheese carrier into the :axial opening of yarn spools or the like, in general, and to such apparatus which has a supporting table for the yarn spool, which table has passing openings of :about the largest diameter of the warp cheese carrier, in particular, whereby the ejection of the warp cheese carrier takes place from the upper side of the table and the insertion of a new warp cheese carrier takes place from the bottom side of the table, and particularly each time through the passing opening of the table.

It is one object of the present invention to provide an apparatus for ejection and insertion of a warp cheese carrier into the :axial opening of yarn spools or the like, wherein the time interval between ejection and insertion of the warp cheese carrier is shortened with the additional feeding, forwarding and removal of the warp cheese carrier in a safe operational and simultaneously foolproof manner of the shortened reversal time. Such reversal is performed, in order, for instance, to exchange board warp cheese carriers for high-valued, metal warp cheese carriers and inserted into the yarn spools substantially for the dyeing process and vice versa.

It is :another object of the present invention to provide an apparatus for ejection and insertion of a warp cheese carrier into the axial opening of yarn spools or the like, which includes a double transport shed movably disposed below the passing opening, in the one half of the double transport shed the ejected warp cheese carrier falls in from above and the other half of which, entering below the passing opening after the ejection, is designed as a catching mouth pointing to a magazine for the warp cheese carriers to be inserted.

It is favorable in .accordance with the present invention, if the double transport shed is displaceably disposed for reciprocating movement.

It is another object of the present invention to provide an apparatus for ejection and insertion of the warp cheese carrier into the axial opening of yarn spools or the like, wherein the transport shed half serving the reception of the ejected warp cheese carrier is of tubular shape and upon movement of the double transport shed moves from the position outside of the end plate of the injection ram into the position above a falling groove.

It is yet another object of the present invention to provide an apparatus for ejection and insertion of a warp cheese carrier into the axial opening of yarn spools or the like, wherein an advantageous structure is realized, if the ejection ram and the insertion ram operate together synchronously and the two receiving chambers of the transport halves are connected together by means of a longitudirral slot.

It is also another object of the present invention to provide an apparatus for ejection and insertion of a warp cheese carrier into the axial opening of yarn spools or the like, wherein a favorable embodiment results by the arrangement of a brake-shoe controlled synchronously with the movement of the double transport shed for stopping the forwardmost of the warp cheese carriers disposed in front of the catching mouth and fed stowingly through the magazine.

Finally, also in accordance with the present invention it is of advantage if the brake-shoe is coupled with an abutment disposed in front thereof seen in the stowing direction of the magazine, which abutment is controlled in a counter-contact to the brake-shoe.

Due to such arrangement, an apparatus is provided with an advantageous structure, which apparatus performs the operation of the ejection and insertion of warp cheese carriers without the change of position of the yarn winding or the like. The reversal takes place without position change of the yarn winding. A rotary table is not necessary. Yet, if it is provided, the reversion takes place without position change thereof. This has the basic advantage of a more careful treatment of the yarn winding, since in accordance with experience in case of a larger spacial reversal timely spaced and apart from each other, the inner yarn layers of a winding draw together. As a consequence, the new inserted warp cheese carrier forming the supporting core often disarranges and in the most unfavorable conditions, respectively, destroys these yarn layers. The double transport shed, moved within the range of the reversal point, controls the proper operation and first of all forced feeding and removal of the inserted 'and ejected, respectively, warp cheese carriers. This is brought about on the one hand due to the tubular, chamber-like formation of the one transport shed half, and, on the other hand, due to the claw-shaped formation of the other half reserved for the feeding of the warp cheese carriers.

The chosen synchronous run of insertion and ejection ram brings about, as has been found a particularly protecting release of the sleeve of the warp cheese carrier from the yarn winding, which sleeve is, as a rule, conically formed, and in particular due to the warp cheese carrier wall set back simultaneously on all sides from the yarn winding wall. The realized brake brings about the desired performance of the functions without any attendance. It prevents the transmission of a stow pressure of the warp cheese carriers lined up in the magazine onto the transport means and exercises in connection with the abutment edge the corresponding control over the magazine storage.

With these and other objects in view which will become apparent in the following detailed description, the present invention will be clearly understood in connection with the accompanying drawings, in which:

FIGURE 1 is a section of a machine equipped with the device designed in accordance with the present invention.

FIG. 2 is a longitudinal section through a mounted metal winding carrier sleeve indicating also the ram heads;

FIG. 3 is a longitudinal section through a paste board warp cheese carrier sleeve;

FIG. 4 is a top plan view of the machine designed in accordance with the present invention;

FIG. 5 is an elevation, partly in section, of the insertion and ejection position of the machine, respectively; and

FIG. 6 is a perspective view of the double transport shed.

Referring now to the drawings, the apparatus comprises a machine frame 1 in which a supporting plate 2 is mounted, which supporting plate 2 is moved within the cycle of the operation of the apparatus in the direction of the arrow R. The supporting table 2 comprises two plates 2' and 2" disposed parallel relative to and spaced apart from each other. It has furthermore passage openings 3. The latter are formed by distancing bushings 4, which hold together simultaneously the plates 2' and 2". The passing openings 3 correspond about to the largest diameter X of the warp cheese carrier 5.

Above the passage opening 3 are disposed discs 6 which have at their upper sides cavity-like supporting hollows, which are complemented to one end face of the yarn winding 7.

The supporting table 2 is driven stepwise by a motor 9 by means of a drive 10 and a coupling 11 by the use of an intermediate Geneva movement 12, which engages a cam 13.

The reversal, that means, the ejection of a warp cheese carrier 5, for instance of metal, and the insertion of a new warp cheese carrier 5', for instance of paper-board, takes place at a single position of the machine. For this purpose a machine stand 14 is projected upwardly beyond the plane of the table plate. This stand 14 comprises a console 36, which extends freely above the holding position of the passing opening 3. The console 36 carries a pneumatic cylinder 37 for an ejection ram 38. The latter passes during its lifting stroke the entire passage opening 3. Its ram head 38 is equipped with a set-off, conically formed point 39. The likewise conical annular shoulder 40 formed by the set-01f corresponds with the

upper end edge

41 and 41, respectively, of the warp cheese carrier 5 and 5', respectively. The stepwise movement of the supporting table 2 is chosen such, that after each step a passage opening 3 comes to lie below the ram 38.

The means for insertion of the new warp cheese carrier 5' comprises a pneumatic cylinder 21. Its insertion ram 42 passes, coming from its ground position, during the lifting stroke likewise over the total length of the passage opening 3. It feeds during its upward movement always one warp cheese carrier 5' into the hollow of the axle of the yarn spool 7 disposed on the supporting table 2. The end plate 42' of the ram 42 which is formed substantially plate-like, continues by formation of a supporting shoulder for the

lower end edge

44 and 44, respectively, of the warp cheese carrier into a centering cone 43 of small height entering into a hollow of the warp cheese carrier.

The feeding of the warp cheese carrier 5 to be inserted and the removal of the ejected warp cheese carrier 5 takes place by means of a double transport shed 45 movably disposed below the passage opening 3. The double transport shed 45 is displaceable to perform a reciprocating movement. One of its chamber halves 45 receives in the corresponding position the carrier 5 inserted falling from above during the synchronous operation of both

rams

38 and 42. It is of tubular shape. The total body is formed of a blank leaving open a slot 45" of about the thickness of the ram 42. The chamber bottom is formed in the one position by the plate-like end plate 42'. The chamber half 45 is movable from its catching position into a position above a falling groove 46. The latter is a fall out opening 47 coordinated to the intermediate wall 48 of the machine.

The other chamber half 45" steps always after the ejection process below the passage opening 3. It is formed of a type of a receiving mouth 49. The latter is pointing with its openings to a rotary plate magazine 25, which while rotating continuously, feeds the warp cheese carrier 5 to be inserted. It has the guide sheets 26. The latter guide the selectively set warp cheese carriers 5' to the outer path. They are thereby inserted stowingly into a channel 50 arranged tangentially to the magazine plate 25. The channel 50 is formed by a straight arranged section 51 of the outer guide board 51 and a brake-shoe 52. The latter holds secure always the next to the last warp cheese carrier during the insertion process under clamping effect. The warp cheese carrier 5 disposed in the catching mouth 49 is moved into insertion position due to displacement of the double transport shed 45 in the direction of the arrow R that means, it is disposed at the end of this displacement movement axially to the insertion ram 42.

A pressure pad 22, moving up and down in the direction of the arrow Y, comes to lie during the insertion process at the upper end side 23 of the yarn spool 7'. The pressure pad 22 is likewise controlled within the cycle. Its lowermost position is always only obtained during standstill of the supporting table 2. The pressure pad 22 has an opening 24 which corresponds about with the diameter of the reduced end of the warp cheese carrier 5 and 5', respectively, in which opening 24 this reduced end of the warp cheese carrier enters during the insertion and ejection process, respectively. The insertion and ejection rams 38 and 42, respectively, move thereby by synchronous control upwardly and downwardly, respectively. On the pressure pad 22 is secured for better guidance of the ejection ram 48 a slide member 22'.

The brake-shoe 52 is mounted about an immovable pin 53. It is designed as a plate and is under the effect of a tension spring 54, which loads the plate in a direction of an adjustable abutment member 55. Furthermore, the brake-shoe 52 is equipped with an abutment 56 set in front of the magazine 25 seen in stowing direction. This abutment 56 performs a doorman function. It permits entrance of one new warp cheese carrier only into the channel 50, after insertion. This arrangement is provided for the purpose, to remove the high stow pressure from the insertion means. By this arrangement disturbances are avoided.

The opening of the channel is thus in dependency upon the insertion process. The brake-shoe is for this purpose equipped with a control arm 57. The latter extends into the operational range of the reciprocating double transport shed 45.

The drive of this double transport shed 45 is obtained by means of a pneumatically operable ram 58, which is connected with the double transport shed 45 by means of a yoke 59 due to formation of welding points. Guide rods 61 sliding in bushings 60 bring about an operational performance stabile as to their positions. The piston of the ram 58 is on both sides subjected to a pressure means, and for this purpose the pressure cylinder 62 is equipped with two end side connections 63.

The yoke carries furthermore an adjustment abutment screw 64, which cooperates with an end switch 65 for the insertion ram 42.

A further end switch 66 projects into the channel 50. It is operated when the double transport shed 45 has received the last warp cheese carrier 5, since then the support by the otherwise present warp cheese carrier next to the last warp cheese carrier 5' falls out and the spring 54, which then pulls up the brake-shoe 52 operating as a switch latch and the latter releases the contact, whereby the machine is brought to a standstill. In case of a still filled-up magazine, on the other hand, the moved out yoke 59 and the projecting nut 67, respectively, prevent the release of the contact. The brake 52 moves only insofar during an insertion movement, until it engages the next to the last warp cheese carrier. This angular movement is used for the purpose, in order to control out the abutment edge 56 in counter-contact from the outer feeding path and to permit its locking function again upon return of the double transport shed 45.

The operation of the apparatus designed in accordance with the present invention is now summarized as follows:

The applied yarn spool steps while passing below a light gate 30 below the ejection ram 38. The latter moves with simultaneously joining of the pressure pad 22, which clamps the yarn winding 7' downwardly and ejects the present warp cheese carrier form the yarn winding hollow. The latter arrives through the passage opening 3 of the supporting table 2 in the chamber half 45' of the double transport shed 45. The latter moves in the direction R1. The double transport shed 45 performs thereby two functions:

It ejects, on the one hand, the warp cheese carrier 5 and guides ahereby simultaneously another winding warp cheese carrier 5' to the insertion ram 42. The ejection ram which remained in its lower position catches now the upwardly moving warp cheese carrier 5 further centering the same. Both rams, controlled synchronously, carry the latter into the axle hole of the yarn winding7' remaining for a short time without winding core. Thereafter both rams as well as the pressure pad 22 return again to their original position.

The reversal can be performed fast and with extreme care. The yarn spool, equipped now with a spool sleeve, is moved by a pneumatically operated ram '68 radial from the table at the next station and, for instance, transfers to a transportation band for further treatment.

The pneumatically controlled feeding of the warp cheese carrier, which feeding is influenced by the brake 52, permits the arrangement of a high machine output with large freedom of service.

The slot 45" permits even the return of the double transport shed 45 when the insertion is not completely terminated. The thereby occurring overlapping movements contribute likewise to a rapid operation.

Instead of ejecting the perforated dyeing sleeve and of inserting the perforated dyeing sleeve, it is also possible to reverse the working procedure with the machine.
