151 l otgfizv 41 44 m United States Patent APPARATUS FOR DEPOSITING WOUND YARN PACKAGES INTO A MAGAZINE Fritz Voegelin, Erlenbach, Switzerland, assignor to Maschinenfabrik Scharer, Erlenbach, Switzerland Application January 3, 1951, Serial No. 204,142

Claims priority, application Switzerland April 4, 1950 4 Claims. (Cl. 226-3) My invention relates to improvements in apparatus for depositing wound yarn packages into a magazine which is supplied through a conveyer.

The apparatus according to my invention comprises a carriage which receives the magazine, and a bottomless box which is removably inserted in the magazine. The bottomless box is subdivided into compartments parallel to each other for storing the wound packages to be deposited. The latter are supplied by the conveyor to an automatically moved chute which guides them toward the respective compartment and causes the magazine and carriage to move step by step in accordance with the spacing of the campartments, when a compartment has been filled.

The main object of my invention is to provide relatively simple automatic means for properly pigeonholing wound packages in a magazine in a number corresponding to the capacity thereof, with a view of facilitating the transport of the packages for further textile operations. Such orientated pigeonholing is not disturbed when the bottomless box, for the purpose of re-inserting it into an empty magazine, is lifted from the full magazine, since the packages released by the box from adjacent compartments, simply close up.

One form of my invention as applied to a winder, and a detail modification thereof are shown in the accompnaying drawings in which Fig. 1 shows the apparatus in sectional elevation,

Fig. 2 a part top plan view,

Figs. 3-5 show part elevations for explaining the mode of operation of the chute and other elements,

Fig. 6 is a cross-section of Fig. 4, involving further elements,

Fig. 7 shows the full magazine after the bottomless box has been removed,

Fig. 8 shows a portion of the apparatus in sectional elevation, involving a detail modification, and

Fig. 9 is a cross-section of Fig. 8.

In Fig. l is shown one end face of an elongated machine frame A on which for example ten like winders B are arranged in line. Each winder B comprises a round rotary element 1 which is disposed on the winder casing by means of a central shaft 2 and on the circumference of which for example seven uniformly spaced winding pegs 3 are mounted, each peg being adapted to receive a bobbin or pirn a. The pirns are moved in succession to a working station by virtue of an automatic stepwise rotation of the element 1. At the said station, the respective peg 3 is automatically coupled to a driving spindle (not shown) which is axially movable in the winder casing. When the package b on pirn a which later is to be used in a shuttle, has reached a predtermined length, the element 1 is indexed through one step so as to move an empty pirn a to said station. The wound package then is stripped, in known manner, from its peg 3 by automatically operating means. The winders B are driven from a common motor via an endless belt 4 which runs over two reversing rollers disposed at the ends of the machine frame A. Intermediary of said rollers, the belt 4 drives the main shaft of each winder B through a friction roller each (not shown).

The reversing roller 5 shown in Fig. 1 through its shaft 6 transmits the drive via an intermediary gearing disposed in a housing 7 onto a cross shaft 8 to which is keyed a sprocket wheel 9 outside the housing 7. From the latter, a control shaft 12 is driven via an endless 2,703,669 Patented Mar. 8, 1955 "ice . chain 10 and a sprocket wheel 11. The shaft 12 is jouring free edge of apron 32. The packages are prevented naled in the two longitudinal walls 13 of the rectangular bottomless pirn-supply box of which the narrow sides are designated by 14. The

box

13, 14 is attached, in a manner not shown, to the adjacent end of the machine frame A.

In the form shown in Figs. l-6, an eccentric disc 15 rigidly secured to shaft 12 actuates a swing arm 17 via a lateral roller 16. The axle 18 of arm 17 is journaled in the box walls 13, and the arm 17 through a spring 19 is held in contact with the eccentric disc 15. The arm 17 periodically actuates a lateral roller 20 of a

bellcrank lever

21, 22 of which the axle pin 23 is journaled in the box walls 13. The said

lever

21, 22 on its arm 22 has an angularly bent end leg 24 to which is secured one end of a chute 25 which serves as package chute and at its free end comprises a downwardly pointing leg 26. Two auxiliary arms 27 with their respective ends are secured to the holding-down part of chute 25 which substantially occupies the entire width of the

bottomless box

13, 14. The said arms 27 also terminate in a downwardly-pointing leg 28 each. An angle iron 29 is secured to the end leg 24 of the said bell crank and carries a set screw 30 which co-operates with a stop 31 fixed to the respective cross-wall 14 of

box

13, 14. An apron 32 is fixed to the box walls 13 intermediary of the chute 25 and the auxiliary arms 27. A clack 34 which normally through a spring 35 is held against stops 36 secured to the box walls 14, is suspended in the

bottomless box

13, 14 from a cross-pin 33.

As the swing arm 17 is actuated by the eccentric disc 15, and the

bell crank

21, 22 is rocked thereby, the chute 25 and the auxiliary arms 27 are swung from the position of rest (Figs. 1 and 4) as shown in Figs. 3 and 5, and then by gravity swing back into the position of rest which is adjustable by means of the set screw 30. In one of the box-walls 13 a slit 13 is provided for the passage of the wound packages a arriving from the winders B. The package released or stripped from a winder B drops by gravity onto a chute 37 which conducts it to an endless conveyer band 38. The latter extends across all the winders B which are arranged in line, and runs over a reversing-roller 39 as shown in Fig. 6. The chute 37 and conveyor band 38 are shown more or less schemati cally. It will be understood, however, that when the package exemplified by the wound bobbin a slides endwise down the chute its forward end will come against the upper side of the conveyor band, and this band moving laterally of such bobbin will tilt it and cause it to be placed on the band with the longitudinal axis of the bobbin extending in the direction of the length of the band. The packages a, head on, are moved by the conveyer 38 in the sense of Fig. 3 through the slit 13' into the

bottomless box

13, 14 in which they are caught by the chute 25 and led downwardly thereon towards the clack 34 to be stopped thereby when the

bell crank

21, 22 is in the position of rest as shown in Figs. 1 and 4. When the

bell crank

21, 22 swings into the position shown in Figs. 3 and 5, the path in

box

13, 14 is cleared for the said package a which then drops from chute 25 onto the stationary apron 32 which is curved in the same sense as chute 25. When the package a arrives at a point beyond the respective end portion of the apron 32,

it drops into a compartment 40 of a second bottomless box 41 which is disposed directly below the first bottomwith two handles 43 and is disposed in a wooden maga' zine 44 which has a metallic frame 45 on top. The

frame 45 has handles 45 on the narrow sides of maga- Zinc 44. When the package a fed from chute 25 to apron 32, does not drop directly into the appurtenant compartment 40 of box 41, but is stopped short thereof as shown 1n Fig. 4, a second package a drops onto the apron 32 as shown m Fig. 3, and the first package is positively moved into the respective compartment 40 by the leg 26 of chute 25 which swings back into the position of rest, the said compartment being directly adjacent the correspondfrom jamming or seizing between chute and clack 34 in that the latter may swing out on its pin 33 under a certain pressure against the action of spring 35. The package a dropping from apron 32 into the box 41 first is caught by the two auxiliary arms 27 which swing together with the chute 25 and project into the be 41 in which they are accommodated in openings 46 in the cross-walls 42 thereof. The said package through the arms 27 first is held in a horizontal position, but is tripped when the arms 27 swing from their position of rest, and drops in the compartment 4t) down to the bottom of magazine 44 or, respectively, down onto the packages already present in said compartment.

After a compartment of box 41 has been filled with packages up to a predetermined level, the magazine 44 and box 4-1 are indexed or moved in the operating direction of the swinging chute 25 through a distance corresponding to that between two adjacent compartments.

For such purpose, the magazine 44 which on top is encircled by the metallic frame 45 having two handles 45, is inserted in a carriage 47 which (as shown in Figs. 1 and 6) is movable on a rail 49 by means of idling rollers 48 pivoted to a longitudinal side wall thereof, and also on a rail 51 by means of idling rollers (Fig. 6). The carriage 47 is open on top and on the longitudinal wall opposite that to which the rollers 48 are pivoted, and the magazine 44 thus may be readily inserted into and withdrawn from said carriage at any track point thereof.

During operation of the mechanical portion of the pigeonholing apparatus of our present invention, a roller arm 53 is rocked back and forth by a cam 52 fixed to control shaft 12, the pin 54 of said arm being pivoted to one of the longitudinal walls 13 of

box

13, 14. On the end of pin 54 outside the box 13, 14 a ratching arm 55 is fixed, which is intended for co-operation with a series of studs 56 fixed to the metal frame 45 of magazine 44. The spacing of the bolts corresponds to that of the compartments 40 in box 41. A second ratching arm 57 pivoted to an intermediary arm 58 fixed to the axle 18 of swing arm 17, serves for the same purpose as the ratching arm 55. After a compartment 49 in box 41 has been supplied with a predetermined number of wound packages, the two auxiliary arms 27 on swinging forward abut against the topmost package in said compartment, whereby the movement of carriage 47 with magazine 44 is initiated in the respective direction. The book of ratching arm 57 then engages that stud 56 of frame 45 which hitherto has supported it, whereupon the arm 57 (which has been correspondingly moved by the swing arm 17) continues and completes the said movement of magazine 44. The distance covered in such movement is defined in accordance with the said spacing of the compartments 40 and of the studs 56 in that a stud as contacts the arm 55, while the arm 57 on swinging backwards engages that stud 56 which is sequential to the stud 56 engaged thereby before.

The carriage 47 and magazine 44 thus are moved step by step, until all the compartments 4%) in box 41 have been supplied with wound packages a. If desired, the carriage 47 on reaching the respective end of its stroke, may actuate an electrical contact means for the purpose either of throwing the winder driving-motor out of operation or of tripping an acoustical or optical signaling device. The carriage 47 with magazine 44 may be run back by hand into its starting position, for which purpose the arm 57 has to be removed from the path of the studs 56. For this purpose, the arm 57 (as shown in Fig. 1) through a wire 59 is connected to a bell-crank lever 6t) pivoted on a pin 61 to one of the longitudinal walls 13 of

box

13, 14. The arm 57 thus may be swung high into a non-operative position by correspondingly rocking the bell crank 6!), whereby the arm 55 also is swung upwardly by a transverse stud. Locking means may be provided for securing the bell crank in the respective terminal position.

The magazine 44, having been filled with packages. may be readily removed from carriage 47 on the free longitudinal side thereof, in order to be replaced by an empty magazine. The box 41 then is lifted from the magazine 44 by the handles 43, whereby the packages pigeonholed in the compartments 49 of box 41 and now released therefrom, close up as shown in Pig. 7 without in any way disturbing their mutual parallel and orientated position in magazine 44. The box 41 then may be inserted into an empty magazine which again is to be supplied with wound yarn packages.

In the operation of the machine the wound bobbins by known mechanism are stripped one by one from the pegs 3 (Fig. 1) of the winder 1 and fall on the chute 37 as shown by the wound bobbin a thereon. The bobbins slide from the chute onto the conveyer belt 38 (Figs. 1 and 6), and because the belt is moving they are orientated to lie lengthwise on the belt as shown in Fig. 6. When the parts are in their positions shown by Fig. 1 the bobbin a when it reaches the belt pulley 39 (Fig. 6) is discharged from the belt and is received by and rolls down the part 25 to come against the clack or stop 34 as shown by the bobbin a in Fig. 1. When the bell crank

lever

21, 22 then is swung by operation of the cam disc 15 to move the parts into their positions shown by Fig. 3 the bobbin a falls from the part 25 and rests upon the stationary apron 32 behind the bobbin a which bobbin a is already resting upon said apron. When the bell crank lever is swung back to its position shown by Fig. 1 the downturned end 26 of the part 25 during such swinging will engage the bobbin a and move it to its position shown in Fig. 4, and while being so moved the bobbin pushes the bobbin a off the apron and lets it fall to and rest on the end of the part 27 also as shown in Fig. 4, and when the bell crank lever then is again swung back to its position shown by Fig. 3 the bobbin a will be swept by the adjacent partition 4-2 of the receptacle 41 from the part 27 and be added to the adjacent stack of bobbins in said receptacle as shown in Fig. 5. When the bobbin 0: added to the stack in the receptacle completes that stack and the bell crank lever swings again to its position shown by Fig. 4 the downturned end 28 of the part 27 will engage such bobbin and move the receptacle to place the next compartment 4% of the receptacle to be filled with bobbins into operative position with respect to the ratching mechanism.

The modification shown in Figs. 8 and 9 differs from the example set out above, by a partly modified con- 3 struction of the means for automatically indexing or rstching the carriage 47 and magazine in accordance with the degree of filling of the compartments 40 in box The said indexing or ratching feed motion is initiated in a manner similar to that described in connection with the first example, viz. in that the front leg 23 of auxiliary arm 27 abuts against the bottomrnost or topmost paeka e oigeouholed in the respective compartment iii. For continuing and limiting the said motion, however, a double wedge 65' is used, which is vertically guided by means of a rod 66 which traverses two bear- 67 secured to the respective longitudinal wall 13 The wedge 65 co-operatcs with pins 68 secured in line to the carriages 43 and performs the functions which in the previous example are carried out by the

arms

55 and 57, as shown in Fig. 3. As reouired for the said ratching movements, the wedge 65 is vertically reciprocated by means of cam 69 fixed to control shaft 22. which cam through a roller 70 co-acts with a top extension 71 provided on the guide rod 66. A cross-member connecting the extension 71 and the re-d 66, traverses a slit provided in the respective longitudinal wail 13 of box 3.3, 3 .4. A spring 72 engaging the extension 73,, tends to hold the wedge 65 in operative position between two adjacent pins 63. The com 69 operates to cor inuously reciprocate the wedge 65 vertir .ly, and the carriage is not moved through a step as lrnig as the indexing or ra .Tifilli. is not initiatod by the auxiliary arms and the v edge 65 is moved upwardly by a 68 to the rear of which it then drops in in order to become operative. The wedge 65 which in co-operation ith the row of pins 68 as indexing and ratching member, normally rests on one of pins 68.

An eccentric disc 73 fixed to control shaft 12 co-acts with the roller 2% of one arm of the bell crank 2i, 22 of chute 25 in order to periodically rock the latter, as described in connection with the first example.

a manner analogous to packages supplied from winding machines, cops produced on a spinning machine, and similar tubes and packages can be properly pigeonholcd in a magazine by means of our present invention.

What I claim as new and desire to secure by Letters Patent, is:
