Definitions

  • I provide the coil assembling and orienting apparatus with a gripper arm which, when in operation, reaches into a container that accommodates a number of yarn coils, then takes an individual coil out of the container and, if that coil is not oriented in the desired direction, supplies it to a directing device which orients the coil and issues it, in the proper position, to another container or supplies it to the place of subsequent fabrication.
  • the storage container from which the gripper arm seizes an individual coil is preferably given the shape of a funnel, and the gripper arm enters into the container at the location of the lowermost bottom point so that the gripper arm, during its travel within the storage container, will always tfind a coil at the lowermost container point as long as any coil is still located in the storage container.
  • the gripper arm may be operated mechanically, pneumatically, or magnetically, for seizing the yarn coils.
  • a mechanical gripper according to the invention is preferably provided with a mechanically controlled closure which closes automatically in response to the gripper terminal member contacting a coil under control by the force which results from the gripper member abutting against the coil.
  • the gripper after entraining a coil from the storage container, can raise the coil to a device which serves to orient the seized coil in a given direction unless the coil happens to be already properly directed.
  • An endless conveyor belt delivers the cop to a chute whose entrance opening is controlled in size relative to the spacing between the offset gravity center of the cop and the ends of the cop, so that the coil tends to tip into a uniformly oriented position and drops through a chute leading to the transporting container.
  • FIG. 1 is .a schematic and partly sectional top view of a gripper device and coil orienting mechanism according to one embodiment of the invention.
  • FIG. 2 is a partial lateral view of the device shown in FIG. 3 is a schematically perspective view, partly in section, of the same gripper device in another position, and including the control mechanisms for its operation.
  • FIGS. 4 and 5 show schematically and in two different operating positions respectively, a modified gripper device for cooperation with a storage container with preoriented coils.
  • FIG. 6 is a longitudinal sectional view of a pneumatic suction member as used in devices according to FIGS. 1 to 5 and taken along line VIVI of FIG. 6b.
  • FIG. 6a shows another operative position of the member according to FIG. 6.
  • FIG. 6b is a cross-sectional view taken along line VI-BVI-B of FIG. 6.
  • FIGS. 7 and 8 show a side view and a sectional view of a funnel-shaped section nozzle applicable in a gripper member otherwise coresponding to FIG. 6.
  • FIG. 9 is a longitudinal sectional View of a gripper member operating with electromagnetic means.
  • FIGS. 10 and 11 show a coil-orienting device in two different operating positions respectively, this device being suitable as a component of apparatus according to FIG. 3 or any of the other preceding embodiments.
  • FIG. 12 is a top view of the device shown in FIGS. 10 and 11;
  • FIG. 13 is a partial end view of the same device, viewed from the left of FIG. 12.
  • the apparatus is provided with a funnel-shaped storage container v1 for cops K which may occupy any position within the container.
  • a gripper device with a flexible gripper arm 2 whose forward end is provided with a suction nozzle 3.
  • the gripper arm 2 is controlled through a rod 13 by an eccentric 4 which cooperates with the cam follower arm 5 driven through shaft 26a from an electric motor 26.
  • Linked to the arm 5' is a piston rod 6 which carries a return spring 6 and which is connected with a piston 8 reciprocating in a cylinder '9.
  • the cylinder 9 has outlet ports 10, and inlet duct 11, and a by-pass 12.
  • the suction nozzle 3 is held and guided by a bell-crank lever 16 which is pivoted at 16a (FIG. 3) to the hub member 5a of the arm 5, the hub member being rotatably seated on a hollow tubular shaft 19 which also serves as a suction conduit and whose interior is joined at 19a for communication with the flexible suction arm 2.
  • the rod '13 is also controlled by another eccentric 14 on the shaft 26a of motor 26.
  • Eccentric .14 cooperates with a follower lever 15 which is pivoted at 15a toa stationary supporting structure 26b on which the motor 26 is mounted.
  • the follower arm '15 is biased by a spring 16 forcing the follower arm cylinder inlet duct 11 (FIG. 1).
  • a throttle T (FIG. 3) can be mounted in the conduit 19 or elsewhere between the suction source Q and the entrance to conduit 2 for the purpose of limiting the amount of the suction current.
  • the two eccentrics 4 and 14 are slowly rotated through a reduction gear (not shown). Due to the action of eccentric 4, the gripper arm 2 is first turned until it is located directly above the lowermost point of the conical or inverted pyramid-shaped container 1. Thereafter the eccentric 14 operates to lower the rod 13 by acting through arm 15 and link 17. As a result, the suction nozzle 3 hits upon some of the cops K in container 1. The nozzle now encounters resistance and presses somewhat against one of the cops, thus pushing it slightly into the pile of cops until the one cop is securely seized by the suction nozzle. The suction arm 2 is then moved upwardly by the rod 13 and thereafter laterally into the position shown by a dot-and-dash line 2 in FIGS. 1 and 2.
  • the funnel-shaped storage container described above may be substituted by the storage box as shown at 31 in FIGS. 4 and 5.
  • the design of the gripper arm 2a and gripper mechanism basically the same as that illustrated in FIGS. 1-3, can be simplified because the gripper arm need only reach the first stack of pre-oriented cops.
  • the box 31 is supported in the inclined position on a suitable support 31a (FIG. 4), and the only motion to be performed by the suction arm 2a, corresponding to pipe 2 in FIGS. 1-3, is upward and downward along an inclined guide rod 2b in the directions as is indicated by a doubleheaded arrow 20 in FIG. 4.
  • the gripper after entraining a cop is then lifted and moved above the trough 23 (FIG. 1) or conveyor belt 32 (FIG. 5) where the gripper member 3 is opened. These operations may be controlled by a cam mechanism similar to the one illustrated in FIG. 3.
  • a gripper member designed as a suction nozzle may also be made to start its sucking action automatically only when it touches a cop K.
  • a suction nozzle of this type, applicable in cooperation with the above-described devices, is illustrated in FIG. 6 and 6a.
  • the active member of the gripper arm is designed to be operated pneumatically as a suction nozzle which is placed against a yarn coil so that the coil covers the suction opening of the nozzle, thus being attached to the nozzle by negative pressure as long as the suction pressure is maintained within the nozzle.
  • the nozzle portion is formed by a ring or sleeve 51 of soft rubber or sponge rubber.
  • Such a suction nozzle is preferably given a widening, funnel-shaped nozzle mouth for providing a better air-tight fit. This nozzle mouth of soft sponge rubber can readily adapt itself to the shape of the yarn coil being seized.
  • the drive for the necessary pivoting, raising or lowering movement of the gripper arm carrying the suction nozzle may likewise be effected by means of suction air.
  • the flexible nozzle portion may also be given a flared-out or funnel-shaped design as shown at 52 in FIGS. 7 and 8 for better air-tight fit around the cop.
  • the active cross section of the suction nozzle must be adapted to the size or weight of the particular coils to be processed.
  • This cross section is preferably between 0.5 cm. and 5 cm. It has been found preferable to dimension the flow cross section so that the suction nozzle is capable of carrying a yarn coil of approximately 250 gram weight with a suction pressure of at least 5000 mm. water column.
  • the nozzle portion 51 or 52 is mounted on a sleeve 53 which is axially displaceable on a valve tube 56 in opposition to the force of a spring 54.
  • the valve tube 56 has lateral outlet openings 55 and is covered at the front by means of a lid 57 fixedly attached to the tube 56.
  • the ports 55 are shown open at top and bottom with cover 57 midway between the bottom inlet and upper outlet of ports '55.
  • FIG. 6a shows the same structure with the ports 55 closed by sleeve 53 in its lowered position, spring 54- not compressed, and hook 39 unlatched, with the suction on and before a cop K is engaged by nozzle 51.
  • the cop K is carried and entrained by the suction nozzle until it is located above the trough structure (23 in FIGS. 1, 2).
  • the gripper arm in the position 2' (FIG. 1), the ambient air is admitted through ports 10, by-pass 12 and duct 18 so that the pressure in the suction tube 56 (FIG. 6) increases, reducing the suction, with the effect of releasing the cop K and permitting the diaphragm 50 to move outwardly.
  • the latch lever 39 now releases the sleeve 53 which is then forced downwardly into the illustrated position of FIG. 6a by means of the spring 54.
  • the gripper is again ready for performing another gripping and conveying operation.
  • the coil After the coil is received in the trough structure 23 (FIGS. 1 to 3), it drops upon an endless belt 61 (FIGS. 10 to 13) whose driving drum is continuously driven by shaft 62 from a suitable drive motor (not shown).
  • the trough-shaped guiding structure 23 is located adjacent to the above-mentioned endless belt 61 at the location where the yarn coils K pass from the gripper onto the belt 61.
  • One of the outer walls 23a of the trough structure forms an acute angle relative to the traveling direction of the belt and a hopper-shaped bottom 23/) is provided in the trough structure which is inclined downwardly toward the belt.
  • a yarn coil K placed into such a trough structure in any position is then forced and guided by the angular wall and inclined bottom of the structure to place itself onto the belt while being directed in the longitudinal belt travel direction thus always securing the proper position on the yarn coils required for the above-mentioned automatic checking and orienting operation.
  • the trough structure 23, as shown in FIGS. -11, is bordered at the forward side, relative to the traveling direction of the upper belt portion, by deflecting wall 23a which extends at an acute angle with respect to the travel direction of belt 61.
  • the bottom or hopper wall 23b of the trough structure is inclined toward the belt 61.
  • the horizontal distance between the supporting surface 59 and the belt 61, i.e. the opening 60', is slightly shorter, namely 5 to 10% less, than the larger spacing of the gravity center from one of the ends of the coil.
  • the device is preferably provided with an endless belt 61 whose most forward reversing point, where the belt passes over the tail pulley 69, is adjacent to a horizontal supporting surface 59 located at approximately the same height as the top portion of the belt 61, but horizontally spaced from the belt at a distance 60.
  • This distance 60 is pro-determined in relation to the coils so that its length is somewhat smaller than the spacing of the gravity center S of the yarn coil from the coil end most remote from the gravity center S; but its length is larger than the spacing of that gravity center S from the nearest coil end.
  • the coil when the coil has its long portion (the portion from the gravity center S to the remotest end) located in front or leading when arriving on the endless belt, the coil will first run onto the horizontal supporting surface and will thereafter tip with the rear work end 141 into the space 60 between supportingsurface 59 and endless belt 61, as soon as the rear end 141 has left the belt. The coil then passes over a slideway 64 in properly oriented position to a collecting container 63. However, if the leading end of the yarn coil on the endless belt 61 is the one that is closer to the gravity center S, the leading end will tip into the space between belt and supporting urface before the leading end can reach the supporting surface. The coil then also passes into the collecting container 63 with the same orientation as the coil mentioned above. Consequently, such a device reverses'the direction of only those coils that are not properly oriented when they pass from the gripper onto the endless belt. As a result, all 'coils in the collecting container are properly oriented for (further fabrication.
  • the gravity center of a cop which has reached the end of belt 61 in position Kb is denoted by S.
  • the gravity center S is not located in the geometric center of the cop but rather closer to the foot end because the foot end 141 (FIG. 10) of the coil core is heavier than the tip.
  • the cop Will tip counterclockwise (as viewed in FIG. 10) off the running belt 61 as soon as the gravity center S passes beyond the reversing roller 69 of the belt, without ever reaching the opposite supporting surface 59. This will always occur when the heavier foot end is the leading end.
  • a cop thus tipping into the opening 60 with its foot end first is shown at Kc in FIG. 10.
  • the cop then passes into a collecting container 63 (FIG. 11) over a slideway or chute 64 with the desired uniform orientation.
  • a pusher 5 which continuously moves horizontally forward and back, then pushes the cop, shown at Kd in FIG. 13, over a horizontal catcher plate 66 from below into stacks in a collecting container 63.
  • the coil can be weighted at one end by means of an iron ring placed upon that one end of the coil.
  • a magnet winding 67 (FIG. 11) connected in an electric circuit 68 may then act magnetically to attract the ring 46 in order to increase the tipping moment of that end of cop K into opening 60.
  • the cop K happens to be so located on the endless belt 61 that the lea-ding end 142 is spaced from the gravity center S a greater distance than the trailing end, then when the gravity center S passes over the reversing roller 69 of belt 61, the leading end 142 will have already reached the supporting surface 39 in the position shown at Kb in'FIG. 11. Consequently, the cop will continue advancing until the trailing end has passed beyond the roller 69. Thereafter, the heavier trailing end will tip clockwise (as viewed in FIG. 11) into the chute 64 as is the case with the cop shown at Ke in FIG. 11. Consequently, the cop is again oriented to exactly the "same direction as in the case first described, and all cops, once collected in the container 63, lie parallel to each other with their .tips pointing uniformly in the same direction.
  • the coil orienting device can be improved and simplified by making the gripper member, for example the suction nozzle 3 according to FIGS. 1 to 3, rotatable about its axis.
  • a deflector Wall 35 (FIG. 1) is then fixedly mounted above the storage container 1 in such a position that it extends parallel to the trough structure 23, chute, or other conveying means into which the entrained coil is released by the gripper member 3.
  • the cop K then places itself into the proper direction by gliding along the deflecting wall 35 and turning to the desired direction if necessary.
  • the gripper member may also be given a magnetic type of design, as illustrated in FIG. 9.
  • a feeler member is preferably provided which is actuated when the gripper member abuts against a yarn coil and which then causes an electromagnet to be energized so that the magnet attracts a magnetic part mounted on the coil, particularly on the coil core, thereby entraining the entire coil out of the storage contamer.
  • the gripper arm 2 in this embodiment carries an electromagnet 75 with an excitation winding 74.
  • the tubular core of the winding is traversed by a feeler pin 73 which is biased by a helical spring 72 to normally protrude out of the winding 74.
  • the 'feeler pin 73 carries an electric contact 71 on its rear (upper) end.
  • the magnetic mouth of the gripper may be elongated to better span the cop.
  • mouth 75a of the gripper hits upon the above-mentioned magnetizable ring 40 of a cop, then the resulting mechanical pressure upon the feeler pin 73 closes the electric contact 711.
  • This energizes the magnet 74 'so that the ring 40 of the cop is attracted.
  • the electric circuit of the magnet 74 is temporarily interrupted by opening an electric switch contact 76 so that the magnet is deenerlgized and releases the cop K. Thereafter the gripper returns to the initial position and another operating circuit can commence.
