  • European Patent application no. 95119751.6 of December 14, 1995 discloses an automatic machine for labeling both long or knee-length socks and short socks.
  • Said machine is substantially composed of a conveyor belt which is arranged substantially horizontally and whereon the socks to be labeled are placed, arranging mutually superimposed pairs of socks so that their tops are arranged proximate to a lateral edge of the conveyor belt, which is actuated with a translatory motion along an advancement direction.
  • the socks to be labeled are positioned so that their tops, i.e., the end regions of their legs, which are meant to receive the label, protrude by a certain extent laterally from the conveyor belt; the tops are supported by suitable supporting means, arranged laterally to the conveyor belt, up to a station for applying the label so that it straddles the two superimposed tops of the pair of socks.
  • a pincer-like element Downstream of the label application station, above the conveyor belt, there is provided a pincer-like element which cyclically engages a labeled pair of socks and moves it towards the opposite lateral edge of the conveyor belt in order to correctly position the pair of socks upstream of a printing station, wherein additional indications, such as for example the trade mark, the size or other information, are applied to a foot of the pair of socks.
  • the machine has a positioning device which engages the pair of socks after applying the label and partially rotates the pair of socks so as to orientate the foot of the socks in a direction substantially perpendicular to the advancement direction of the conveyor belt, i.e., in a correct position for undergoing the subsequent printing operation.
  • the above machine has proved to be susceptible of further improvements, particularly as regards the device for positioning short-type socks, which is located downstream of the label-applying station.
  • the aim of the present invention is to provide a sock positioning device, particularly for short socks, in labeling machines of the type described in the above-mentioned patent application, which is highly reliable in operation.
  • an object of the present invention is to provide a sock positioning device which, applied to a machine of the above described type, allows, even in the case of short socks, to print on the foot of the socks which is overlapped on the legs without causing any problem as regards the application of the label to the tops of the socks.

  • the sock positioning device is meant to be installed preferably on labeling machines of the type described in European Patent application no. 95119751.6, i.e., of the type comprising a conveyor belt 2 which can move along an advancement direction, indicated by the arrow 3, and along which there is provided a station 4 for applying a label 5 at the tops 6 of a pair of socks 7, which are mutually superimposed and positioned so that their tops 6 are proximate to a lateral edge 8 of the conveyor belt 2.
  • labeling machines of the type described in European Patent application no. 95119751.6, i.e., of the type comprising a conveyor belt 2 which can move along an advancement direction, indicated by the arrow 3, and along which there is provided a station 4 for applying a label 5 at the tops 6 of a pair of socks 7, which are mutually superimposed and positioned so that their tops 6 are proximate to a lateral edge 8 of the conveyor belt 2.
  • the pair of socks 7 is arranged on the conveyor belt 2 so that the feet 9 are folded onto the legs 10.
  • the legs 10 are orientated transversely to the advancement direction 3 and the end portion 9a of the feet on the toe side is folded again onto the remaining part 9b of the feet 9 in order to keep clear the region for applying the label 5.
  • a printing station 11 for applying additional indications to the foot of the socks, is arranged along the conveyor belt 2 downstream of the station 4 for applying the label 5 with respect to the advancement direction 3 of the conveyor belt 2.
  • the positioning device 1, 1a is interposed between the station 4 for applying the label 5 and the printing station 11.
  • the positioning device 1, 1a comprises overturning means which are adapted to act on the folded end portion 9a of the feet 9 of the socks in order to fully extend the feet 9 onto the legs 10 of the socks, so as to prepare the socks for the subsequent printing operation.
  • the overturning means comprise means for dispensing at least one jet of compressed air which is directed towards the top 6 of the pair of socks 7 and is adapted to strike the region where the end portion 9a of the feet overlaps the remaining part 9b of the feet of the socks.
  • the means for dispensing at least one jet of compressed air comprise a pair of nozzles 12a and 12b which are connected to ducts 13 for feeding compressed air and are mutually spaced parallel to the advancement direction 3.
  • the nozzles 12a and 12b have dispensing directions which are orientated transversely to the advancement direction 3 and converge towards the lateral edge 8 of the conveyor belt 2, proximate to which the tops 6 of the socks 7 are arranged.
  • the positioning device in its first embodiment, also comprises means for moving the nozzles 12a and 12b in a direction which is substantially perpendicular to the plane of arrangement of the face of the conveyor belt 2 on which the socks 7 are deposited.
  • the nozzles 12a and 12b which can be simply constituted by gauged hoses, are connected at the lower ends of two arms 14a and 14b of a bifurcated support, generally designated by the reference numeral 15, which faces, by means of the lower ends of the two arms 14a and 14b, the face of the conveyor belt 2 that supports the socks 7.
  • the two arms 14a and 14b are joined in an upward region by a cross-member 16 which is supported, so that it can slide in a direction which is substantially perpendicular to the face of the conveyor belt 2 that supports the socks 7, by a block 17 which is fixed to a bar 18, which is arranged transversely to the advancement direction 3 and is fixed to the supporting structure of the machine, above the conveyor belt 2.
  • the block 17 has two guiding shafts 19a and 19b which are orientated at right angles to the face of the conveyor belt 2 that supports the socks 7, or vertically if the conveyor belt 2 is arranged horizontally, and slidingly engage seats 20a and 20b formed in the cross-member 16 of the bifurcated support 15.
  • the means for moving the bifurcated support 15 in the direction at right angles to the face of the conveyor belt 2 that supports the socks 7 are conveniently constituted by a linear actuator, which is fitted on the block 17 and acts on the cross-member 16 of the bifurcated support 15 in order to produce the sliding of the bifurcated support 15 along the guiding shafts 19a and 19b.
  • the linear actuator is preferably constituted, as shown, by a step motor 22 which is mounted on the block 17 and is connected, by means of its output shaft 22a, to a threaded shaft 23 which is coupled to a female thread 24 formed in the cross-member 16, parallel to the seats 20a and 20b.
  • Each pair of socks 7 to be labeled and printed is deposited on the conveyor belt 2 so that the top 6 is arranged proximate to the lateral edge 8 of the conveyor belt 2, as described in European Patent application no. 95119751.6, and the feet 9 of the socks are folded above the legs 10, which are orientated at right angles to the advancement direction 3.
  • the folding of the feet 9 onto the legs 10 causes the toe 9a of the feet to overlap the region of the legs 10 proximate to the tops 6, i.e., the region meant to receive the label 5 in the station 4. Accordingly, the end portion 9a of the feet 9 on the toe side is folded again onto the remaining part 9b of the feet 9, so as to keep clear said region for the application of the label 5.
  • the pair of socks 7 thus labeled passes with its end portion 9a in front of the nozzles 12a and 12b.
  • the step motor 22 is activated so as to lower the nozzles 12a and 12b towards the conveyor belt 2 until they are in a position which is suitable to strike, with the compressed-air jets, the folded end portion 9a in order to overturn said end portion 9a onto the legs 10 of the pair of socks 7, thus fully extending the feet 9 onto the legs 10 of the socks.
  • the overturning means comprise an abutment which can be inserted, on the opposite side with respect to the tops 6, between the folded end portion 9a (toe) of the feet 9 and the underlying remaining part 9b of the feet 9, and comprise means for gripping and moving the pair of socks 7 with respect to the conveyor belt 2 transversely to the advancement direction 3, towards the lateral edge 25 of the conveyor belt 2 which is opposite to the lateral edge 8 whereat the tops 6 of the socks 7 are positioned during the loading of the labeling machine.
  • the above-mentioned abutment is formed by a bar 30 which is supported above the conveyor belt 2 and is parallel to the advancement direction 3.
  • the bar 30 is fixed, at its longitudinal ends, to two posts 31a and 31b which are arranged at right angles to the bar 30 and are joined, above the bar 30, by a transverse shaft 32.
  • the transverse shaft 32 is supported by a slider 33 so that it can oscillate about its own axis 32a, which is substantially parallel to the advancement direction 3.
  • the slider 33 is supported, so that it can slide substantially at right angles to the face of the conveyor belt 2 that supports the socks 7, by a block 34 which can be fixed to a bar 35, which is in turn fixed to the supporting structure of the labeling machine above the conveyor belt 2.
  • the block 34 is provided with two shafts 36a and 36b which are orientated at right angles to the face of the conveyor belt 2 that supports the socks 7 and slidingly pass through a pair of seats 37a and 37b formed in the slider 33.
  • the device according to the present invention in its second embodiment, comprises first movement means for causing the oscillation of the bar 30 about the axis 32a of the shaft 32, i.e., about an axis which is substantially parallel to the advancement direction 3, and second movement means for shifting the bar 30 towards or away from the face of the conveyor belt 2 that supports the socks 7.
  • the first movement means are conveniently constituted by a pneumatic cylinder 38, which is fitted on the slider 33 and faces, with the stem of its piston, one of the two posts 31a and 31b; in the illustrated case, it faces the post 31b.
  • the actuation of the pneumatic cylinder 38 causes the oscillation of the posts 31a and 31b, of the bar 30 and of the shaft 32 about the axis 32a in contrast with the action of elastic return means which are constituted, for example, by a helical spring 40 which is interposed between an abutment 41 which is rigidly coupled to the post 31b and an abutment 42 which is rigidly coupled to the slider 33.
  • the second means for moving the bar 30 are conveniently constituted by a linear actuator which acts on the slider 33 to move it along the guiding shafts 36a and 36b.
  • the linear actuator is preferably constituted by a step motor 43 which is mounted on the block 34 and is connected, by means of its output shaft 43a, to a threaded shaft 44 which is parallel to the guiding shafts 36a and 36b and engages a female thread 45 formed in the slider 33.
  • shoulders 46a and 46b which limit the sliding of the slider 33 towards the conveyor belt 2.
  • the device according to the present invention in its second embodiment, comprises means for gripping and moving the pair of socks substantially at right angles to the advancement direction 3 with respect to the conveyor belt 2, in order to move the pair of socks 7 towards the lateral edge 25 of the conveyor belt 2 which is opposite with respect to the lateral edge 8.
  • the gripping and moving means can be constituted, for example, by pincers 50 which are supported so that they can slide along a bar 51 which is fixed to the supporting structure of the labeling machine, above the conveyor belt 2 and below the bar 35.
  • the pincers 50 with their translatory motion at right angles to the advancement direction 3, can be moved until they are located at the bar 30.
  • the opening and closing movement of the pincers 50 is actuated by a pneumatic cylinder 52.
  • the pincers 50 can be constituted by the sock gripping and moving means already described and illustrated in European Patent application No. 95119751.6.
  • the socks 7 are arranged on the conveyor belt 2 in a manner similar to the one already described with reference to the operation of the device in its first embodiment.
  • the socks 7 pass, with the end portion 9a of their feet 9 folded onto the remaining part 9b of their feet 9, proximate to the bar 30 which, by means of the actuation of the step motor 43, has been moved to a level which is slightly higher than the level of the upper face of the remaining part 9b of the feet 9.
  • the pneumatic cylinder 38 has been actuated beforehand so as to swing the bar 30 away from the lateral edge 8 of the conveyor belt 2.
  • the bar 30 is parallel to the line for folding the end portion 9a with respect to the remaining part 9b of the feet and faces the inlet of the region where the end portion 9a overlaps the remaining part 9b of the feet.
  • the pneumatic cylinder 38 is deactivated, i.e., actuated in the opposite direction, so that the elastic reaction of the spring 40 causes the oscillation of the bar 30 about the axis 32a of the shaft 32 and the consequent insertion of the bar 30 between the end portion 9a and the remaining part 9b of the feet 9 of the socks.
  • the pincers 50 are actuated in order to grip the pair of socks 7 on the opposite side with respect to the tops 6 and to move them transversely to the advancement direction 3, towards the lateral edge 25 of the conveyor belt 2.
  • the device according to the present invention fully achieves the intended aim, since it allows highly reliable operation of labeling machines of the type described in European Patent application no. 95119751.6 in the labeling and printing of short-type socks as well.
  • the materials used, as well as the dimensions, may be any according to requirements and the state of the art.
