Abstract
Description
- The present invention relates to an automatic loading unit for stockings and tights for fixing machines.
- The present invention is in particular applied in the field of final processing of stockings where the stockings made must be subjected to special fixing treatments intended to give the stockings the final shape and appearance.
- Such fixing treatments are carried out by subjecting the stockings placed on suitable processing profiles to special treatments, for example thermal treatments.
- To place the stockings on the processing profiles, automatic loading units were developed which allow the operator to operate in a position that is remote relative to the processing profiles, avoiding direct contact with them (since they are heated to high temperatures).
- In particular, there are prior art loading units comprising a pair of profiles which are coplanar during the loading step and on which an operator places a stocking, at the same time carrying out a visual inspection to find any defects.
- The profiles are then transferred near to two processing profiles, allowing the stocking to be transferred to the latter.
- In some prior art systems, the fixing machine profiles are positioned so that they are coplanar and opposite each other, meaning that during stocking transfer, the two loading profiles on which the operator placed the stocking are also rotated relative to each other book-style so that they are positioned parallel with and opposite each other, allowing the transfer to the fixing machine profiles.

WO 00/37728 A - Document
DE 199 02 228 A1 shows a hosiery fashioning machine, especially for fine stockings, comprising a number of formers in the required shape to hold the stockings, to be carried on a continuous conveyor path in succession through at least one treatment station and at least one loading and unloading station. The assembly has a system to inspect the stockings on the formers, which are in pairs on carriers to move on two parallel swing axes parallel to the longitudinal axes of the formers. Each of the two formers on a carrier is coupled to a swing mechanism to be moved so that they are folded together on two parallel planes and opened out for inspection where they both lie on a common plane. The two formers on each carrier rotate together on a common axis parallel to both swing axes, coupled to a mechanism to rotate them in a given angular range. The carriers are coupled or can be coupled to the conveyor system. The mechanisms for the swing and rotation movements are controlled at a given position on the conveyor path so that, at one point, the two formers are opened out to be carried onwards and be rotated round a given angle so that the front and rear sides are in the field of view of the operative. - One of the disadvantages encountered in prior art loading units is difficulty loading manually due to the book-style open position of the loading profiles, which causes significant deformation of the stockings and necessitates repeated application of excessive force by the operator in charge of manual loading.
- In this context, the present invention has for a main aim to propose an automatic loading unit for stockings and tights for fixing machines which is free of the above-mentioned disadvantages.
- In particular, the present invention has for an aim to provide an automatic loading unit for stockings and tights for fixing machines which at the same time allows easy and rapid loading of the stockings on the profiles and easy visual inspection of the stockings during the loading step to check for any defects in the stockings to be fixed and packaged. The technical purpose indicated and the aims specified are substantially achieved by an automatic loading unit for stockings and tights for fixing machines with the technical characteristics described in one or more of the appended claims. Further features and advantages of the present invention are more apparent from the non-limiting description which follows of a preferred, non-limiting embodiment of an automatic loading unit for stockings and tights for fixing machines according to the invention, illustrated in the accompanying drawings, in which:
-
Figure 1 is a schematic plan view of an automatic loading unit for stockings and tights for fixing machines according to the present invention; -
Figure 2 is a schematic side view of the unit ofFigure 1 during an operating step; -
Figure 3 is a schematic top view of the operating steps of a machine; -
Figures 4 and5 illustrate details of the loading unit ofFigure 1 . - With reference to the accompanying drawings, the numeral 1 denotes as a whole an automatic loading unit for stockings and tights for fixing machines according to the present invention.
- The unit 1 comprises a
carrousel 2 rotating about a vertical axis, the outside of the carrousel supporting at least one pair ofprofiles 3 designed to receive a stocking 100 (the latter being schematically illustrated inFigure 2 ) in a first operating station "a" and to transfer it onto theprofiles 102 of a fixing machine, positioned in a second operating station "b". - With reference to the example embodiment illustrated in the accompanying drawings, the
profiles 3 each comprise a flat,vertical wall 4, preferably tapered towards the top portion to facilitate application of thestocking 100. - Each
wall 4 also comprises an L-shaped section, supported by alower plate 5, integral with thewall 4. - According to the invention, in the loading station "a" the
profiles 3 are positioned in a diverging configuration, substantially forming a V. - Thanks to the diverging configuration of the
profiles 3, during application of thestockings 100 on theprofiles 3, thestockings 100 are not excessively deformed and the operator (schematically illustrated and labelled 101 inFigure 1 ) does not have to apply excessive force to deform thestocking 100 during its application on theprofiles 3. - Moreover, thanks to this configuration of the pair of
profiles 3 the operator is in any event able to suitably inspect the entire surface area of thestockings 100. - The
profiles 3, being in a diverging configuration, hold thestocking 100 "open" and therefore clearly visible for theoperator 101. - The unit 1 according to the invention also comprises a
transfer mechanism 6 for transferring the pair ofprofiles 3 from the loading station "a" (illustrated inFigure 1 ), in which the pair ofprofiles 3 receives thestocking 100, to a second operating position, coinciding with the transfer station "b" (illustrated inFigures 1 and2 ), in which the pair ofprofiles 3 releases thestocking 100 to a pair of fixing boards 102 (illustrated inFigure 2 ) belonging to a fixing machine (not illustrated) intended to carry out stocking 100 fixing and finishing operations. - With reference to the accompanying drawings, the
mechanism 6 comprises amechanism 9 for moving each pair ofprofiles 3 with a combined movement towards/away from each other and rotation relative to each other during movement of the profiles through the different operating stations and in particular from the loading station "a" to the transfer station "b". - In particular with reference to
Figures 1 and4 , theprofile movement mechanism 9 comprises a Y-shaped support 10 for each pair ofprofiles 3, in which divergingguides 7 are made for eachprofile 3 of each pair of loading profiles. - Advantageously, in combination with the
support 10, theprofile movement mechanism 9 comprises ajoint 11 mechanically connecting theprofiles 3 to each other. - In particular, with reference to
Figure 4 , thejoint 11 comprises three rod-shaped elements end portions - The
first end 22a of the first rod-shaped element 22 is hinged to arod 26 and itssecond end 22b is hinged to thefirst end 23a of the second rod-shaped element. - The two
rods 26 are each integral with arespective bushing 28 which slides on a sharedtransversal shaft 25. - Similarly, the
first end 24a of the third rod-shaped element 24 is hinged to a bushing 28 and itssecond end 24b is hinged to thesecond end 23b of the second rod-shaped element 23. - A
central portion 23c of the second rod-shaped element 23 is also hinged to a supportingelement 21 fixed to thetransversal shaft 25 and able to slide along ashaft 29 positioned radially relative to the carrousel and in a position which is generally symmetrical relative to the Y-shaped support 10. - In this way, by moving only one of the three rod-shaped elements, the other two rod-shaped elements are also moved, moving the
bushings 28 and therefore therods 26 towards or away from each other. - The supporting
element 21 may also be controlled by an actuator which controls its movement along theshaft 29 in one or more of the operating stations. - It must also be specified that the movement of one of the three rod-shaped elements may be performed according to known methods, for example using an actuator acting on the first 22 or the third 24 rod-shaped element.
- As shown in
Figure 1 , in the preferred embodiment the unit 1 comprises four pairs ofprofiles 3, each having a respectiveprofile movement mechanism 9. In particular, therotary carrousel 2 comprises acircular plate 15, whose rotation is driven by agear motor 8, to which a pair ofprofiles 3 is connected every 90°, so that the fourpairs 3 are equidistant and opposite each other in pairs relative to the carrousel. - Each pair of
profiles 3 can also be translated vertically relative to thecircular plate 15 of thecarrousel 2, allowing the pair ofprofiles 3 to reach a position in which it is elevated relative to thefixing board 102 in the transfer station "b" (Figure 2 ). - To guarantee the above-mentioned vertical movement, the
carrousel 2 comprises four uprights 16 (only two of which are visible inFigure 2 ) extending from thecircular plate 15 and connected to each other at top portions by anothercircular plate 17. The pairs ofprofiles 3 and the corresponding foursupports 10 are slidably connected torespective uprights 16. - Translation of the
profiles 3 along theuprights 16 is driven by amotor 18 which drives atoothed belt 19 to which thesupport 10 is connected (Figure 2 ). It should be noticed thatFigure 2 shows two pairs ofprofiles 3, one in theupper position 3a, and one in thelower position 3b. - In particular, each of the four pairs of
profiles 3 can translated towards and away from the axis of rotation of thecarrousel 2. -
Figure 1 shows four operating stations, but there may be a different number of stations. - In particular, in the example described, the loading station "a" is the station at the
operator 101 position, whilst the transfer station "b" is the station diametrically opposed to the loading station "a". - Between the loading station "a" and the transfer station "b" there is a lifting station "c" in which the pairs of
profiles 3 are lifted vertically. Between the transfer station "b" and the loading station "a" there is an outfeed station "d". - During operation, the
operator 101 loads astocking 100 on the twoprofiles 3 which are in the opened out position, separated by an angle α approximately between 110° and 130° and in front of the operator in the loading station "a" (Figure 1 ), in the lowered position. - Advantageously, during this step the stocking or
tights 100 already applied on theprofiles 3 is lit up so that it can be checked for defects. - Then the pair of
profiles 3 supporting thestocking 100 is rotated through approximately 90° clockwise, bringing it to the lifting station "c" where theprofiles 3 are lifted and moved radially during profile rotation, thanks to engagement of abearing 33 integral with the radial movement of theprofiles 3 and able to slide in a cam 30 (detail inFigure 5 ) positioned eccentrically relative to the carrousel axis. - During this movement, the
cam 30 guides theprofiles 3 in an outward radial direction, so that therods 26 move forwards, also pulling the connectingrods 27 which connect them to theguides 7 of thesupport 10, until theends 31 of the connectingrods 27 are at theforward end point 32 of theguide 7. - During this step the connecting
rods 27, operatively connected to theprofiles 3, are constrained to follow the diverging stretches of theguides 7 and to rotate about theend 31, thus causing a first rotation with closing of theprofiles 3 relative to each other. - Also in the lifting station "c" the
jointed linkage 11 is driven to rotate theelement 23 and move therods 26 towards each other, at the same time causing a further rotation of the connectingrods 27 about theend 31 engaged with theguides 7 and therefore a further rotation with closing of theprofiles 3 relative to each other. - When the movement is complete, the loading profiles have performed a vertical translation, a relative rotation and a movement towards/away from each other, at the end of which they are in a raised position and parallel with each other.
- At the same time, another pair of
profiles 3 is presented to theoperator 101, who applies anew stocking 100 on them. - When the
new stocking 100 has been applied on the new pair ofprofiles 3, thecarrousel 2 rotates through a further 90°, bringing the first pair ofprofiles 3 to the transfer station "b" and the second pair ofprofiles 3 to the lifting station "c". - In the station "b" the stocking is transferred from the loading profiles 3 to the fixing
boards 102. - As already indicated, each
profile 3 comprisesrespective walls 4 to which respective L-shaped sections are connected which can be positioned opposite each other to form a substantially U-shaped seat. - In contrast, the two fixing
boards 102 comprise a single wall having a vertical dimension that is much greater than the vertical dimension of theprofiles 3 and much greater than the length of thestockings 100. - The transversal dimensions of the fixing
boards 102 are less than the dimensions of the L-shaped sections of theprofiles 3, allowing the fixingboards 102 to be inserted in the U-shaped seat formed. - Therefore, if the
profiles 3 are vertically aligned with the fixingboards 102, that is to say, theprofiles 3 are centred on the fixingboards 102 and the pair ofprofiles 3 is lowered onto the pair of fixingboards 102, eachprofile 3 is applied on the corresponding fixingboard 102, receiving the fixingboard 102 inside the U-shaped seat obtained by joining the two L-shaped walls. - When the
profiles 3 are completely lowered onto the fixingboards 102, the stocking 100 supported by theprofiles 3 is gradually removed from the latter and is gradually fitted onto the fixingboards 102, until thewhole stocking 100 is completely transferred to the fixingboard 102, as illustrated inFigure 2 . - The pair of profiles in the
lower position 3b, represents the pair ofprofiles 3a in the upper position, and the stocking 100 which they support, when theprofiles 3 have been lowered onto the fixingboards 102. - Moreover, once the stocking 100 has been released to the fixing
boards 102, theprofiles 3 can be disengaged from the fixingboards 102 to continue the loading cycle. - In this way, once the
profiles 3 have been lowered onto the fixingboards 102, transferring the stocking 100 to the fixing boards, theprofiles 3 move away from each other along theguide 7 due to the joint 11 operated in the opposite direction to its previous operation, and they are also moved radially by a suitable actuator towards the axis of rotation of thecarrousel 2, leaving the dimensions of the fixingboards 102. - At this point the
profiles 3 which performed the transfer are in the lowered position, opened out relative to each other in a "V" shape and can return towards the loading station "a". - In the meantime another stocking 100 may be applied on the third pair of
profiles 3. - When the
first stocking 100 has been transferred to the fixingboards 102, thecarrousel 2 rotates through a further 90°, bringing the first pair ofprofiles 3 to the outfeed station "d". - At this point a
fourth stocking 100 is applied on the fourth pair ofprofiles 3. The second and third pairs ofprofiles 3 are subjected to what has already been described with reference to the first pair ofprofiles 3. - A further 90° rotation by the
carrousel 2 returns the unit to the starting conditions. - It must be emphasised that
carrousel 2 rotation timing, that is to say, the time for which each pair ofprofiles 3 remains in the station occupied, is determined by the time for which a pair ofprofiles 3 remains in the operating station requiring the most time to carry out its operating steps. - In the preferred embodiment of the invention, said operating station is the loading station "a", although the reduction of the force needed for loading thanks to the invention allows this operation to be carried out more rapidly and without damaging the stocking being processed.
- The invention provides various advantages.
- One important advantage is the fact that a loading unit according to the present invention allows an
operator 101 to perform manual loading more easily and rapidly than the prior art units. - In particular, this advantage is obtained by the diverging position of the profiles which does not cause excessive deformation of the stockings and at the same time allows an excellent view of the stocking.
- This latter aspect is also very important, since the
operator 101 can visually check for any defects on the stocking 100 during the initial loading step. The invention described above is susceptible of industrial application and may be modified and adapted in several ways without thereby departing from the scope of the inventive concept. Moreover, all details of the invention may be substituted by technically equivalent elements.
