Definitions

  • the present invention relates to a feeding device, and more particularly to a device for feeding spools to a winding machine.
  • the present invention mainly consists in a feeding device having a plurality of supply carrying means mounted on a conveyor belt driven by rotary drums and passing over supply receiving stations.
  • Each of the supply carrying means is provided with an outlet opening and has closure means closing the outlet opening and holding therein objects, such as empty spools, which are tending to drop through the outlet opening.
  • Actuating means are provided on the conveyer band and on the supporting means to provide an actuating impulse.
  • spring loaded feeler means are provided which engage objects contained in the supply receiving means and move to an operative position when no objects are present in the supply receiving means.
  • Motion transmitting means connect the feeler means, the actuating means, and the closure means so that the actuating means only open the closure means when the feeler means engage no object in the supply receiving means.
  • the feeler means are directly connected to the closure means actuating the same when moving to operative position.
  • Actuating means resiliently urge the feeler means into operative position, but as long as an object is present in the supply receiving means, the feeler means cannot perform such movement so that no object is released from the supply carrying means.
  • coupling means which are controlled by the feeler means, are arranged between the actuating means and the closure means and controlled by the feeler means so that the Cir ice
  • closure means are only opened when coupled by the coupling means.
  • the feeler means perform such coupling when they are in operative position which they assume when no object is present in the supply receiving means.
  • a modified embodiment of the present invention uses the feeler means directly for holding objects in the supply carrying means.
  • the feeler means have a holding portion engaging a projection on the object in the supply carrying means when the feeler means are in inoperative position, and an object is present in the supply receiving means.
  • the feeler means are pivoted by a spring to an operative position and release the object in the supply carrying means so that the same may drop into the supply receiving means.
  • closure means may be provided for closing the outlet of the supply carrying means.
  • a rotary cam member which is operatively connected to a closure means in the above-described modified embodiment. At intervals determined by the cam member, the closure means remain closed and do not permit dropping of a spool which has been released by the feeler means.
  • the cam member permits an actuating lever, which is controlled by the cam member, to project into the path of the closure means so that the closure means are opened when the conveyer belt moves to a position in which the outlet opening of the supply carrying means, and the supply receiving means coincide.
  • the two first-mentioned embodiments are preferably provided with a similar arrangement.
  • a cam follower sliding on a rotary cam member actuates in these two embodiments coupling means arranged between the actuating means and the closure member. According to the position of the cam member the actuating member is connected, or disconnected, respectively, to the other parts of the motion transmitting means so that at predetermined intervals the closure means is not open although the feeler means do not engage a spool in the supply receiving means.
  • Fig. l is a side view of a preferred embodiment of the present invention.
  • Fig. 2 is a side view similar to Fig. 1 of a modified embodiment
  • Fig. 3 is a front view of another preferred embodiment of the present invention.
  • Fig. 4 is a front view of a further modified embodiment of the present invention.
  • FIG. 1 supporting means 1 and 2 support by means of a shaft 3 a rotary drum member 4 over which a conveyer belt 9 passes which is driven by the rotary drum 4.
  • On the conveyer belt 9 supporting members 10 sliding on rails 10 are mounted spaced from each other and support supply carrying means 11 which are provided at the lower end thereof with an outlet opening closed by a closure means 13 to prevent dropping of an object 12, such as an empty spool, through the opening.
  • the closure means is pivotally mounted on the supply carrying means 11 on pivoting pins 14 and may be pivoted to an through the chute 8 must only take place when the movable conveyer belt has transported the supply carrying means to a position above the chute S.
  • an actuatingmember is mounted on the supporting member 10 and engages the actuating twoarmed lever 21, 21' which is pivoted on the supporting means on the pivoting pin 5. Engagement of the arm 21 by the actuating member 21 causes movement of the other arm 21 of the actuating lever by which a coupling rod 22 is moved in an axial direction thereof. Coupling rod 22 is slidably mounted on the feeler means 19.
  • a spring 33 is mounted on the coupling rod 22 abutting at one end thereof on the abutment member 31 which is fixedly secured to coupling rod 22, and on the other end thereof on the feeler means 19, so that when the coupling rod 22 is moved in axial direction by the actuating lever 21, 21', the feeler means 19 are resiliently urged in an anti-clockwise direction (Fig. l) to pivot about the shaft mounted on the supporting means 34.
  • a further two-armed lever 17, 16 is pivotally mounted on shaft 6 on the supporting means 2 engaging with one end thereof the projection 15 on the closure means 13 and on the other end thereof a rod 18 which is pivotally secured to the feeler means 19.
  • connection between the actuating lever 21, 21 and the feeler means 19 is interrupted at predetermined intervals by a cam member 28 which is rotatably mounted on the supporting means by means of a shaft 30, and is provided with a depressed portion 29 which causes the cam follower 27 to pivot about the shaft 26 whereby the other end 25 of the cam follower is moved to the position shown in Fig. 1. If, however, the cam follower passes over the remainder of the cam track on the cam member 28, the rod 24 is moved downwardly and the coupling rod 22 is pulled downwardly by the sleeve 23 secured to rod 24. Thereby the end of the coupling rod 22 is dis engaged from the lever arm 21, the rod 22 pivoting about a support on the feeler means 19, so that the movement of the lever arm 21' cannot actuate the feeler means 19 to move to an operative position.
  • the device operates as follows:
  • the projection 20 engages the actuating member 21, 21 the coupling rod 22 moves axially and the fixed abutment 31 thereon acts on spring 33 to resiliently press the feeler means 19 towards the supply receiving means.
  • An object 12 on the supply receiving means prevents such movement. If, however, no object 12' is present on the supply receiving means, the feeler means 19 moves in a counterclockwise direction in Fig. l.
  • the rod 18 turns the twoarmed lever 16, 17 in a clockwise direction so that the upper end thereof. engaging the projection 15 of the closure member 13, pivots the closure member to an object releasing position.
  • a rotary actuating member 29' is arranged on the shaft 3 for common rotation with the drum 4.
  • a plurality of feeding stations each comprising a supply carrying means and a supply receiving means, a lever 16, 17, a feeler means 19 and a rod 18 are provided along the conveyor belt 9.
  • the shaft 5 supporting the actuating lever 21, 21' extends along the stations and actuates the same by lever portions 21 through coupling rods 22 and springs 33.
  • FIG. 3 The embodiment shown in Fig. 3 is provided with a conveyer belt 9 which is moved in a similar manner as in the previous embodiments.
  • Supply varrying means 38 are secured to the conveyer belt and have an outlet opening at the bottom thereof which is closed by the closure means 14 which are pivotally mounted on the conveyer belt 9 by means of a pivoting pin 61.
  • Below the supply carrying means 33 supply receiving means 46 is arranged, so that an object 12, such as a spool, may drop into the supply receiving means 46 when the conveyor belt transports the supply carrying means 38 through a position above the supply receiving means 46.
  • a feeler means 64 is pivotally mounted by means of bracket 6.”: on the conveyer belt 9 and is urged by spring means 63 to engage an object 12 in the supply receiving means 46.
  • An actuating lever 53 is pivotally mounted on the supply receiving means, or on the supporting means, respectively, and projects into the path of an actuating lever 54, 55 which is pivotally mounted at 56 on the conveyer belt 9.
  • a coupling member 57 is pivotally mounted with one end thereof, while the other end of the coupling member is provided with an engaging portion 69 which engages the projecting arm 62 of. the closure means 40.
  • a link 59 pivotally connects the hook portion of the feeler means 64 with the coupling member at 58 so that the couplingmember is moved to the disengaging position shown in Fig. 3 when the feeler means 64 engage an object 12' in the supply receiving means 46.
  • the spring 63' pivots the feeler means to an operative position so that the link 59 pulls the cou pling member 57 to the left in Fig. 3 and the engaging portion 60 engages the projecting arm 62 of the closure means 40.
  • the lever 54, 55 when actuated by lever 53, pulls the coupling member and therewith the projecting portion 62 up Wardly causing pivoting of the closure member about the pivoting point 61 to an object releasing position permitting dropping of an object 12 into the supply receiving means.
  • an arrangement is provided for pivoting the lever 53 to a position in which it does not project into the path of the lever arm 54 so that the closure means 41 ⁇ are not actuated.
  • the pivoting of the lever 53 is carried out at predetermined intervals by cam 28 rotating about a shaft 30 and actuating a cam follower 27 pivotaily mounted at 26.
  • the rocking motion of the cam follo "er is transmitted by pivoted rods 51, 52 and a closing lever 50, pivoted at 58,
  • the supply receiving means is tobular so that the objects contained therein are prevented i from dropping into the chute 8 by a closing member 49 which is pivoted at 58 and integral with the closing lever 50. While the spools are shifted in the Winding machine, the cam member 28 keeps the closing member 49 in a position closing the bottom opening of the tubular supply receiving means 46.
  • the arrangement is such that while the closing member 49 opens and permits a spool 12 to drop into the chute 8, the actuating lever is pivoted out of the path of the lever arm 54 and no further spool 12 can be supplied to the supply receiving means while the closing member 49 is in open position.
  • FIG. 4 A further modified embodiment is illustrated in Fig. 4 which again shows a conveyer belt 9 moving in the direction of the arrow 66 and supporting a supply carrying means 38 containing an object 12. mounted below the supply carrying means is a tubular supply receiving means 46 so that an object 12 may drop into the supply receiving means when the movement of the belt 9 brings the supply carrying means into alignment with the supply receiving means.
  • the objects 12 which are used in this arrangement are spools provided with a projecting ifange. Such projecting flange is engaged by a holding means which is connected by a rod 43 to the feeler means 44. Spring means 42' tend to turn the holding portion 45 and the feeler means 44 in one direction. in the event that there is a spool 12 present in the supplying receiving means 46 the feeler means 44 remain in inoperative position and the spool 12 is held in the supply carrying means by the holding means 45 engaging the flange on the spool 12. When, however, no spool is present in the supply receiving means 46 the feeler means 44 are pivoted to an operative position causing the holding means 45 to release the object 12 which drops into the supply receiving means.
  • a cam member 28 rotating about shaft 36] is provided and pivots closing lever 50 about the pivoting point 48 by means of a rod 51 whereby closing member 49 on the opening at the bottom of the tubular supply receiving means 46 is opened.
