Definitions

  • Each supported bobbin is pushed in longitudinal direction thereof to an unbalanced position in which the wide end and the center of gravity thereof are located over the opening so that each bobbin drops through the opening with the wide end leading whereby the bobbins are uniformly oriented.
  • BACKGROUND OF THE INVENTION Apparatus for sorting random oriented conical bobbins or other objects in such a manner that all narrow ends point in one direction, and all wide ends of the bobbins point in the opposite direction.
  • random oriented is used in the present application to describe bobbins whose narrow ends, or wide ends, respectively, do not point in the same direction.
  • the sorting and orienting of bobbins is required in textile machines such as spinning machines, twisting machines, fiyer machines and winding machines.
  • oriented bobbins are required for supplying bobbins to automatic donning apparatus of spinning machines or twisting machines.
  • donning apparatus includes transporting devices for transporting the bobbins which are held by holding members on a conveyor in an upright position. In order to load the conveyor, bobbins in a substantially vertical position with the wider end pointing downward, are dropped onto the holding members of the conveyor.
  • Another object of the invention is to provide a method and apparatus for rapidly orienting and separating random oriented objects such as bobbins.
  • Another object of the invention is to discharge all oriented bobbins successively through an outlet opening at the same point of the apparatus.
  • Another object of the invention is to provide a bobbin orienting apparatus which can be added to existent bobbin changing apparatus.
  • Another object of the invention is to provide a bobbin orienting apparatus which can be easily adapted to operation with bobbins of different length and diameter.
  • the present invention relates to an arrangement by which random oriented objects, specifically bobbins are oriented so that all bobbins are discharged from the apparatus in a position in which the same end leads. For example, if the wider end of a tapered bobbin leads during dropping of the bobbin, it can be directly placed on a holding member or spindle.
  • the invention is not limited, however, to random oriented nited States Patent O 3,456,770 Patented July 22, 1969 bobbins, but other objects having different ends may also be oriented by the arrangement of the invention.
  • a preferred method of the invention comprises the steps of consecutively placing random oriented objects bobbins in a supported position over an opening, and moving each supported bobbin longitudinally relative to the opening to an unbalanced position in which a first end and the center of gravity of the respective bobbin are located over the opening while the second end of the bobbin is still supported. Consequently, each bobbin drops through the opening with the first end leading whereby the bobbins are uniformly oriented.
  • the opening is shorter than the length of each bobbin and wider than the wider end thereof.
  • the random oriented bobbins are horizontally disposed to form a vertical stack, and successively drop to a horizontally supported position when an unbalanced bobbin drops through the opening.
  • Each bobbin is moved horizontally in longitudinal direction thereof and of the opening to the unbalanced position.
  • One embodiment of the apparatus according to the invention comprises feeding means, preferably a vertical chute holding a stack of random oriented bobbins, for successiveively supplying bobbins to supporting means having an elongated opening whose length is shorter than the length of the bobbins and whose width is greater than the width of the same.
  • Operating means preferably including two operating members located at the ends of the opening, engaged only first ends of each supported bobbin, for example the wide end of a tapered bobbin, for moving the same in longitudinal direction thereof to the unbalanced position in which the first end thereof and the center of gravity are located over the opening, while the second end is still supported on the supporting means.
  • the operating members are preferably simultaneously reciprocated toward and away from each other and the bobbin between the same, and are disposed at same levels to engage the wide end of the supported bobbin and to pass the narrow end of the same. Consequently, only one of the operating members engages the wide end of the supported bobbin during movement of the operating members toward each other. In this manner, the wide end of the bobbin is pushed to a position located over the opening, while the narrow end is pushed farther over the supporting means, and the bobbin is unbalanced and drops with the wide end leading through the opening.
  • a bobbin can be discharged in this manner through the opening even if it is the lowest bobbin of a stack of random oriented bobbins located in a vertical chute.
  • the operating member which passes the narrow end of the lowest and supported bobbin engages the bobbin directly above the same. Since this higher bobbin cannot be longitudinally displaced since it is located in a chute, damage to the operating member is prevented by making the operating members resilient or by selecting the length of the strokes of the operating members so that the same push the bobbins a short distance only whereupon further longitudinal movement of the bobbins takes place due to inertia.
  • a separating member is inserted between the lowest and supported bobbin, and the next higher bobbin so that the stack of bobbins is supported while the lowest bobbin is displaced to fall through the opening.
  • the separating means for example a flat plate
  • the operating member which cooperates with the narrow end of the lowest bobbin, can pass the same without engaging the next higher bobbin.
  • the lowest bobbin can be freely discharged through the opening without interference of the next higher bobbin, particularly if the separating plate is retracted only after the lowest bobbin has dropped through the opening.
  • the next higher bobbin drops to a position supported over the opening.
  • electromagnetic means as drive means for the generating members and separating means, but it is also possible to manually operate the apparatus.
  • FIG. 1 is a front elevation, partially in vertical section, illustrating an embodiment of the invention in combination with a conveyor band for transporting bobbins;
  • FIG. 2 is a horizontal sectional view taken on line 22 in FIG. 1, but showing a bobbin in a position differently oriented than the bobbin shown in FIG. 1;
  • FIG. 3 is a fragmentary side elevation of a portion of the apparatus of FIG. 1 shown in vertical section;
  • FIG. 4 is a circuit diagram illustrating the electric circuit of the apparatus shown in FIG. 1;
  • FIG. 5 is a fregmentary front elevation, partially in vertical section, illustrating a modification of the embodiment of FIG. 1;
  • FIG. 6 is a fragmentary side elevation illustrating a part of the embodiment of FIG. 5.
  • the apparatus has an upright chute 10 having a rectangular outlet 13 at the lower end thereof which opens into a sorting chamber 11 communicating with the interior of a transversely projecting casing 19, best seen in FIGS. 2 and 3.
  • the bottom plate of the casing has a rectangular opening 15 whose length is shorter than the length of a bobbin, and whose width is greater than the greatest width of the bobbin. Opening 15 is disposed at the upper end of a downwardly tapering chute 12, which ends in a lower ends in a lower outlet opening 81 having a diameter corresponding to the diameter of the wider end of a bobbin.
  • a vertical stack of random oriented bobbins 16 is located in feeding chute 10.
  • Bobbins 16 are slender tapered frustoconical tubes having wide ends 18 and narrow ends 17, some of the bobbins in chute 10 having ends pointing to one side, and other bobbins having ends pointing to the other side.
  • the cross section of chute 10 is rectangular, and corresponds to the dimensions of bobbins 16 so that the bobbins successively drop to a position in which the lowest bobbin 16" rests with its ends 13" and 17" on portions 72 and 73 of a support plate 14 which is a portion of the bottom wall of casing 19.
  • Supporting portions 72 and 73 are located adjacent the shorter sides of the rectangular opening 15, and are shown to be fiat.
  • a difierent contuor, preventing lateral displacement of the supported bobbin 16" may be provided and have a shape corresponding to the shape of the recess 74 in FIG. 6 which shows a part of a modified embodiment.
  • the casing 19 houses operating means for discharging the lowest tube 16" through opening 15 into the lower chute 12, and separating means including a separating plate which is located at a level slightly above the lowest supported bobbin 16".
  • Drive means 20 include an electromagnet 29 having terminals and operating a magnetizable armature 27 to move in the direction of the arrow A into an inner bore 31 of electromagnet 29 when the same is energized.
  • Push rod 26 carries the separating plate 25, and portions 34 and respectively cooperate with arms 36 and 37 of a pair of operating members 23 and 24 pivotally mounted on pivots 21 and 22 and having end portions and 41 respectively located in sorting chamber 11 at opposite ends of the opening 15 and the lowest bobbin 16", as best seen in FIG. 2.
  • End portions 40 and 41 of operating members 23 and 24 are located at a level which is higher than the level of the highest point of the narrow end 17", but lower than the highest point of the wider end 18" of the lowest bobbin 16", as best seen in FIG. 1.
  • Separating plate 25 is located slightly above the highest point at the wide end 18" of bobbin 16", as shown in FIGS. 1 and 3.
  • separating plate 25 When electromagnet 29 is energized, separating plate 25 is advanced to the position shown in broken lines in FIG. 3 and slightly raises bobbin 16' which is located above the lowest supported bobbin 16". Thereupon, end portions 34 and 35 of drive member 28 engage arms 36 and 37 so that end portions 40 and 41 of operating members 23 and 24 move toward each other to the position shown in broken lines in FIG. 2 only for operating member 24.
  • end portion 40 is located above the highest point of the narrow end 17", while end portion 41 is located directly opposite the wide end 18 of bobbin 16".
  • end portion 40 is located opposite the wide end 18", while end portion 41 is located above the narrow end 17 Therefore, irrespective of the orientation and position of the lowest bobbin 16", only one of the end portions 40 or 41 of the operating members 23 or 24 will engage 'the wide end of the lowest bobbin 16 and push the same in longitudinal direction while the other operating member is ineffective.
  • the pivotal movement of the dropping bobbin is best shown in chain lines in FIG. 5, which illustrates a modification.
  • the chute 12 guides the dropping bobbin toward the outlet opening 81 at the lower end of chute 12 so that the bobbin drops in a substantially vertical position with its wider end leading out of outlet 81 onto a frustoconical holder 45 fitting into the wide end of the bobbin and being carried by a conveyor band 46 so that the bobbin is transported by the same to another part of the textile machine where bobbins are donned on spindles.
  • another bobbin 16a is transported by the conveyor 46 on a holder 45', while the next following holder 45 is located under outlet 81 ready to receive bobbin 16" when the same drops through chute 12.
  • electromagnet 29 When a bobbin 16" has been discharged through opening 15, electromagnet 29 is de-energized, and spring 32 retracts members 28 and 26 so that portions 34 and 35 release operating members 23 and 24 which are returned to the initial inoperative positions by springs 38 and 39.
  • the separating means 25, 26, and the operating means 23, 24, 40, 41 are operated by drive means including electromagnet 29 and spring 32 in timed relationship so that first separating plate 25 is moved to the operative position shown in chain lines in FIG. 3 for supporting the bobbins in chute 10, and for separating the next higher bobbin from the lowest bobbin 16" whereupon the operating means 23, 24 are actuated by members 34, 35 to perform inward reciprocating strokes indicated by arrows B and C in FIG. 2 for discharging the lowest bobbin 16".
  • the low chute 12 is not absolutely necessary, since the discharged bobbins drop out of opening 15 oriented in the same direction with the wider end leading. However, when it is desired to drop the bobbins directly onto conveyor means 46, 45, the conveyor is stepwise operated and whenever a bobbin is discharged through chute 12, a holder 45 registers with the circular outlet 81 whose diameter is only slightly greater than the diameter of the wider ends of the bobbins.
  • the motor driving the conveyor 46, 45 is controlled by switches in accordance with the electric circuit shown in FIG. 4.
  • a discharged bobbin passing through outlet 81 operates switch actuator 47 of a switch means 48 so that a relay 61 is energized and relay contact member 53 of a switch 54 is displaced to the position shown in chain lines in FIG. 4 so that drive motor 49 is energized through lines 62 from a source of voltage 80 and moves conveyor band 46 with holders 45 in the direction of the arrow D. Since switch actuator 47 is operated by a dropping bobbin directly before the same drops onto a holder 45, the movement of the conveyor band 46 is started when the dropped bobbin is already held by holder 45.
  • Another sensing switch 51 has a switch actuator 64 located in the path of movement of holders 45 so that the arrival of a holder 45 under the outlet 81 of chute 12 is sensed, Switch 51 closes and effects energization of the relay 52 which acts on contact member 53 to move the same to the position shown in solid lines in FIG. 4 so that the circuit of motor 49 is interrupted and the same is stopped together with conveyor band 46 in a position in which a holder 45 is located directly under outlet 81.
  • the operating members may be located over the opening 15 in the inner positions thereof so that the wide end of the respective bobbin 16" is reliably pushed to a position located over the opening 15. It is, however, not absolutely necessary to move operating members 23 and 24 so far inward, since a short stroke is sutficient to push the lowest bobbin 16" in longitudinal direction whereupon the bobbin moves due to inertia to the position in which its wide end 18" is located over opening 15.
  • the separating means 25, 26 has not only the purpose of raising the upper bobbins and thus separating the lowest bobbin from the next higher bobbin during the longitudinal movement of the lowest bobbin 16", but also performs the additional function of loosening the stack of bobbins when the same are jammed in chute 10, or in a hopper or container above the same.
  • FIG. 5 corresponds in every respect to the construction described with reference to FIGS. 1 to 3, and corresponding parts are indicated by like reference numerals. The only difference is found in the construction of opening 15' in the support plate 14a under the sorting chamber 11a.
  • the embodiment of FIG. 5 provides an opening 15' which is substantially shorter than the length of the bobbins, but longer than the distance from the wide end of a bobbin to its center of gravity.
  • the shorter length of opening 15' has the advantage that bobbins of different lengths can be oriented by the apparatus.
  • a bobbin 16" longitudinally displaced by one of the operating members 23 or 24 to a position in which its wide end is located over opening 15, has its center of gravity also located over opening 15 so that the bobbin is unbalanced and drops with its wide end leading out of opening 15' and into chute 12.
  • the apparatus can also be adapted for bobbins having different widths.
  • Detachable supporting members 70 and 71 are placed at the ends of the elongated opening 15, and are formed with angular recesses 74, as best seen in FIG. 6.
  • the height of the supporting members 70 is selected so that the wide end of the respective bobbin 16" supported thereon is located at the level of operating members 23 and 24, while the narrower end is located below the same.
  • Recesses 74 permit the longitudinal movement of the bobbins by operating members 23 or 24, but hold the same against displacement into casing 19.
  • FIG. 5 shows the operating members 23 and 24 with end portions 40 and 41 in the inner position for discharging the bobbin 16", which is shown longitudinally displaced with the wide end located over opening 15 and the narrow end supported on support plate 14a.
  • Bobbin 16" is about to drop with the wide end leading through the opening while pivoting about the portion of support plate 14a located on the right side as viewed in FIG. 5 to the positions shown in chain lines in FIG. 5.
