Definitions

  • the subject of the present invention is a stacking device intended in particular, but not exclusively, for stacking textile pieces such as hosiery during manufacture.
  • stacking, turning, folding, etc. consecutive to a determined operation for the presentation of the articles at the next work station are currently carried out manually taking into account the difficulties mentioned above.
  • the stacking and possible folding operations are operations which, although necessary, significantly increase the manufacturing costs since during this time the operation to be carried out on the station is suspended.
  • US Pat. No. 4,214,541 discloses the provision consisting in providing, in a stacking device, means for folding an article, synchronized with the cutting operations, for folding the article (a pillowcase). in two.
  • the present invention has for its first object an automatic stacking device allowing the operator working on a sewing work station, for example, to be freed from the worry of the presentation of the articles on the next work station. She can thus devote herself solely to the actual assembly work.
  • a second object is the production of a fully automated device which allows precise and repetitive stacking so that the stacks are presented in a constant manner and all include a determined number of parts.
  • a third object of the present invention is a device which allows automatic discharge of the batteries and constitutes a step towards the complete automation of the manufacture of at least certain simple parts.
  • the device for stacking textile pieces is characterized in that it comprises a support for the textile piece, at least one clamp for gripping the textile piece, said clamp being driven by an alternating movement between a position where it is located above the support and a position in which it comes above an unloading table, movable vertically, a guide bar being arranged opposite the table.
  • the device when you simply have to stack the pieces, without any other manipulation, between the output of a sewing machine for example and a stacking table, the device allows you to grab the piece at the output of the workstation and route it on top of the stack Training.
  • the vertical reciprocating movement of the table makes it possible to permanently obtain an identical level of discharge, whatever the height of the stack being formed.
  • the support intended to receive the textile piece at the outlet of the machine is mounted on a mobile platform driven by an alternating horizontal movement moving between the outlet of the machine and the inlet of the stack formation table.
  • the support is provided with lateral extension means.
  • the latter can be extended so that the part is stretched in a substantially vertical plane and can be deposited substantially flat on the stacking table.
  • the support is pivotally mounted on the mobile platform, the pivoting angle of the support being adjustable. It is thus possible to bring the upper part of the support below the table on which the machine rests in order to allow the articles to be turned over.
  • the device comprises an alignment cylinder equipped with a clamp coming to grip an edge of the piece to align it with the support so that the clamps can grip said piece in determined locations in view transport to the stacking table.
  • the device comprises a resizing cylinder making it possible to adapt the parameters of the folding of the pieces along a determined line and, for example, the bottom, whatever the dimensions or item sizes.
  • the stacking device is, in all its versions, controlled by an automaton, triggering the different sequences necessary for the operation of the device one after the other.
  • This automaton is indexed on the machine intended to carry out the main operation and, for example, on a sewing machine, the automaton being able to be started from the work station proper as well as certain settings such as, for example, the size of the articles.
  • the machine itself, controlling the automaton can itself be controlled by the latter for a final operation. That is to say that there is an interaction between the operating machine and the stacking device, this interaction resulting in particular in a stop of the operation of the machine when a predetermined number of parts or articles is stacked on the table.
  • the sewing machine will be a so-called "rubbery” machine intended to sew to the upper part of a panty or undergarment, comprising a belt opening and two thigh openings, an elastic belt, the machine performing simultaneously with the installation and sewing of the elastic belt, cutting or shaving the upper part of the panties.
  • the textile piece received from the previous station comprises an assembly of all the constituent parts, namely the front part and the rear part sewn along their common line or bottom, possibly including a gusset which can be simply built or overlocked.
  • the machine considered cuts the belt part and sews an elastic band intended to constitute the belt on the outside of the article which is present at the moment in the form of a band having notches intended to constitute the leg loops.
  • the article is finished on a following station which performs the second side seam overlock. To do this, the article must, before stacking, be returned as will be described later. But it is understood that the present invention is in no way limited to this particular operation, nor to this type of article and that it can be implemented even if it is a question of stacking simple strips of rectangular fabric.
  • FIG. 1 there is a sewing machine M at the outlet of which is arranged the device according to the invention.
  • the apparatus shown - schematically in FIG. 1 essentially consists of a support 1 intended to receive the pieces at the outlet of the sewing machine M mounted on a table T, of gripping means 2, capable of taking the pieces from the support 1, these gripping means being movable between the support 1 and a stacking table 3.
  • the movement of the gripping means 2 is a movement horizontal.
  • the simplest operation of the device is as follows: the part falls under its own weight on the support 1; it is gripped by the gripping means 2 and is transported on the stacking table 3. But, as will be described later, the device can also fold the part and even turn it over.
  • Fig. 1 the various members are mounted on a chassis 10 which rests on the ground and on the table T of the sewing machine M.
  • the base 20 of the chassis rests on the ground, (contrary to what appears in FIG. 1 for representation conveniences) as well as the base 21 of the support 1 which is located between the table 3 and the machine M.
  • the upper part 22 of the chassis 20 constitutes a frame carrying slides 23 on which bearings 24 integral with a plate 25 secured to a magnetic sleeve 26 driven by a magnet (not shown) circulating under the influence of a pressurized fluid in the tubing 27.
  • the plate 25 carries two vertical guides 28 on which slides a support 13 secured to the rod of an actuator 14.
  • clamps 2 The purpose of this actuator is to raise and lower the clamps 2 so that they can grasp the part located on the support 1, lift it then transport it above the stacking table 3.
  • the extension of the cylinder rod 9 causes the clamp 2 to close and its retraction to open.
  • the inside of the jaws 11, 12 is advantageously provided with a non-slip textile layer.
  • the clamps 2 can open, close under the action of the jacks 9, go up or down under the action of the jack 14, move horizontally from a position overhanging the support 1 to a position overhanging the table d 'stacking 3.
  • all these movements are clocked by the machine from the end of an operation of the machine M.
  • the stacking table 3 is driven by a vertical reciprocating movement by means. one or more cylinders (not shown). It is indeed appropriate that the knitting pieces are deposited on the pile 4 in an appropriate arrangement and, in the example shown. horizontally. The height of the stack in formation from the ground must therefore be constant regardless of the number of articles making up the stack. Such an adjustment of the level of the upper part of the stack cannot be carried out precisely by lowering the table 3 the thickness of an article, each time a part is deposited. Also, the table descends and its position, during the ascent, is determined by a sensor 7.
  • the device comprises a presser flap 5 mounted articulated around a horizontal fixed hinge. This flap passes from a substantially vertical position shown in FIG. 1, when the clamps arrive above the stack, in a horizontal position when the clamps are moved forward.
  • the movements of the presser flap 5 are controlled by a rotary actuator (not shown).
  • a guide bar 8 integral with the frame, whose role will be explained later, is arranged at the entrance to table 3.
  • the sewn part When the machine has to work flat on a part of a part which must be closed in order to constitute substantially a circumference, the sewn part performs a rotational movement, that is to say that the sewing of an elastic belt, for example leads to a substantially circular movement of the belt as will be explained later.
  • the device comprises an alignment clamp 30 driven in horizontal translation along the front face (in FIG. 1) of the table T by a jack (not shown).
  • This clamp comprises a fixed jaw 31 on which a movable jaw 32 is articulated.
  • the closing of the clamp 30 is controlled by a small jack 33.
  • the clamp 30 makes movement, under the action of its jack, towards the outside of the machine. During this movement it grasps a part of the manufactured part which, in the case of the fitting of an elastic belt is the rear part of the latter and the jaw 32 closes on the jaw 31. After this closing, the pliers make a rapid withdrawal movement which brings the gripped part of the belt over lead of the support 1. It will be noted that during this operation the elastic band constituting the belt has not yet been cut so that the article remains linked to the next article by this belt. Thanks to this alignment clamp, an edge of the piece always falls in a precise position on the support 1. In fact, and as will be described below, the device uses gravity to place the piece on the support 1. After the elastic belt has been cut, the article is held by blocking the support 1 against a stop 50 as will be explained below.
  • the support 1 could be arbitrary. It was sufficient for it to be able to receive the pieces falling from the machine after cutting the elastic band, pieces which were taken up by the clamps 2.
  • the support 1 advantageously consists of two parallel uprights 34.35 joined by at least a rod 36.
  • This rod 36 is controlled by a jack 46 making it possible to vary the distance of the upright 35 relative to the upright 34 which remains in a fixed plane.
  • the transverse rod 36 is only a control rod which centers a support bar 37 sliding in a bearing 38.
  • the support 1 comes to wedge the edge of the part disposed on the side of the machine, (on the left in FIG. 1) against a stop 50 which also serves to avoid the fall of the part after cutting the elastic band. constituting the belt.
  • a movable support 1 between the outlet of the machine M and the stacking table 3.
  • the support 1 rests on a frame 21 resting itself on the ground. In the device's rest position, the support 1 is in the vertical position.
  • On the frame 21 are fixed two horizontal slides 38, 39 on which a spacer 40 can slide.
  • the body of a jack 41 On the spacer 40 is pivotally mounted the body of a jack 41 whose rod is articulated at 42 on a plate 43 carrying a certain number of perforations making it possible to adjust the stroke of the rod of the jack 41.
  • the upright 34 can pivot around the axis 44 carried by the frame 21.
  • the axis 21 is itself integral with the rod of a jack 45 which can move all of the parts constituting the support 1 in horizontal translation on the frame 21.
  • the frame formed by the uprights 34.35 and the bars 36.37 can come below the table T of the machine , behind the exit plan of the sewn pieces.
  • the device makes it possible to adjust the stroke of the piece between the outlet of the machine M and the support 1. It comprises for this purpose a size-up jack 49 whose body is arranged below the table T of the machine M and the rod of which is secured to a kind of stick or slide 47 of which one end is free while the second end is guided by a slot 48 in which it can take a number of determined positions and, for example 3 corresponding to large sizes, medium sizes and small sizes. Instead of falling directly onto the support, the part slides on the stick 47 which is at a distance from the front face of the table T determined by the position of its end in the groove 48.
  • This size adjustment device does not will not be described in the operation of the machine since, for a given size, it is adjusted once and for all, from the work station.
  • the jack 49 moves the stock 47 to a determined distance from the table of the machine M so that the stroke of the article before it reaches the support is adjusted so that the bottom seam or , more generally the fold line is deposited exactly on the upper bar 37 of the support 1.
  • the part blocked by the support 1 falls on the support by its own weight and turning around as soon as the contact of the support 1 on the stop 50 is released by a rearward movement of the upper part of the support.
  • the machine M comprises a supplier of an elastic band C which is sewn to the upper part of the part P, the outer face P1 of which faces the upper part of the machine. Sewing is in progress.
  • the front part of the part falls from the front face of the table T by sliding on the stick 47.
  • the support 1 pivots forward so that the frame comes into contact with the external face P1.
  • the table 3 descends while the flap 5 is raised.
  • the grippers 2 start their movement towards the machine.
  • the clamp 30 grasps the piece P and aligns it with the edge of the table T.
  • Fig. 3 the flap 5 is returned to a horizontal position and the table 3 rises to the level determined by the sensors 7 (Fig. 1).
  • the alignment clamp 30 is open.
  • the elastic band C is cut so that the part P falls on the support, its face P2 being turned outside the support, its bottom resting on the bar 37 thanks to the pruning cylinder and the stock 47.
  • the piece P is still in a torch since it is only suspended at one point on the belt.
  • the clamps 2 arrive below the support 1, outside the stacking table.
  • Fig. 4 the part P is extended under the action of the actuator 46 so that a corner of the frame passes through the opening of a leg turn.
  • the part P2 is then grasped by the clamps 2 which rise by lifting the part after the support 1 has returned to a substantially vertical position, then tilts in the opposite direction, towards the table, under the influence of the jack 41 ( FIG. 1) so as to facilitate the sliding of the part P2 on the support 1.
  • the support 1 accompanies the grippers 2 over part of their travel and, practically up to at the entrance to table 3.
  • Fig. 6 it can be seen how the part P2 passes from a substantially vertical position to a horizontal position.
  • the flap 5 is raised to allow the passage of the clamps and the part P2.
  • the clamps 2 continue their translational movement towards the rear of the table 3 by driving the bottom of the part.
  • the presence of the guide bar 8 prevents any contact between the part P2 and the upper part of the stack 4 in formation, which would produce disorders in the stack.
  • the clamps 2 open at the end of the stroke and the piece P2 is placed on top of the stack 4.
  • the rear part of the piece P2 remains suspended on the bar 8.
  • the traction of the piece P2 on the bar 8 allows also to clear some folds.
  • the support 1 pivots clockwise and moves back towards the table T. On the sewing machine M, the sewing of a new piece has started.
  • the device then takes the position shown in FIG. 2. Going down the table 3 slides the rear part of the part P2 onto the guide bar 8. During the movement of raising the table, this rear part will remain below the bar. A new cycle begins again allowing the stacking of a new part.
  • the sensors 7 make it possible to know, at any time, the height of the stack 4 which corresponds, of course, to the presence in this stack of a certain number of articles, of course a variable number for each type of item.
  • this information is transmitted to the automaton which stops the operations mentioned above.
  • the table 3 is moved in a horizontal plane towards the machine to allow the operator to take hold of the stack and place it on a conveyor belt. This movement is carried out using cylinders - (not shown). It is also possible to provide an automatic unloading system bringing the table 3 directly above a conveyor belt.
