Definitions

  • the present invention relates to a method and device for the automatic change of pots intended to receive wicks of fibers coming from textile machines and more particularly from carding machines.
  • Carding machines are textile machines which have been known for a very long time and which serve to produce a thin web, starting from disordered fibers, the fibers of which are oriented in the direction of their advance in the machine.
  • This veil is, in certain processes such as those called combed and semi-combed, gathered in a sheet in the form of a funnel to form a ribbon or a wick of much lesser width.
  • This wick is then generally deposited in cylindrical pots of large capacity by a potting or potting head.
  • the wick is deposited in the almost full pot by a rotating potting head, the diameter of which is slightly less than the inside radius of the pot.
  • the circle described by the potting head is almost tangent internally to the surface of the pot, so that a small cylindrical part in the center of the pot remains free of wicks.
  • the pot itself is animated by a slow movement of rotation.
  • the wick is therefore deposited in the pot in the form of successive loops, or turns, each of which is slightly offset from the previous one. These turns gradually cover the entire periphery of the pot, then, when the latter has completed a full turn, a second layer is deposited, and so on.
  • the carding machine is a machine of great inertia, which cannot be started or stopped in a very short time. Any stoppage of the card therefore constitutes a waste of time, therefore a significant loss of production.
  • the change of pot requires the presence of the worker when the pot at work happens to be completely filled. On the other hand, this change of pot requires a certain time, during which the wick delivered by the card is deposited on the ground, between the full pot and the new empty pot.
  • the part of the wick that fell between the two pots can, if it is too long, get caught in the mechanisms for changing the pot or in the wheels of the pots, which causes other wastes of time for the operator.
  • the present invention aims to provide modern potters with a system avoiding the drawbacks mentioned above, by allowing the automatic breaking of the wick between the full pot and the empty pot.
  • Systems have already been imagined, but these systems are not adapted to the high potting speeds that are used today, for example in the semi-combed field, namely about 400m / min.
  • Such a mechanism is described in document FR-A-2 204 562 and consists of a fixed upper part below which a carriage can move, comprising a tray intended to collect the ribbon delivered during the change of pot or box.
  • the ribbon is deposited on the tray when the carriage moves from right to left, then continues to be deposited on the tray when the carriage leaves to the right until the whole set of ribbon is pushed back into the new jar.
  • the tray covers almost the entire surface of the pot and the amount of ribbon or wick deposited is very large.
  • Document FR-A-2 311 739 describes a device for cutting the wick using a simultaneous action of a pinching member and means for driving the wick by rollers driven in rotation.
  • This device ensures at the same time the normal feeding and the guiding of the drill bit. deliver in the pot. It is therefore fixedly arranged above the pot during filling and does not undergo any translation. In addition, it occupies a very important place in height which is no longer admissible in modern machines with quantities of wicks delivered much higher than before.
  • the problems to be solved are on the one hand to reduce the quantity of wick deposited on the table and on the other hand to reduce the overall height of this table so as to be able to bring the pot as close as possible to the potting head .
  • the present invention makes it possible to solve these problems by simple and effective means as defined in claims 1 to 6.
  • This table is hinged around a horizontal hinge, on the side of the card, so that it can fold down, and you can let a pot pass in front of it.
  • This table also includes a clamping block to trap the wick during the pot change, a freely rotating cylinder mounted on a spring with a vertical axis pushing it upwards, and a small drop sheet directed towards the empty jar.
  • a rotary cylinder driven by a motor and a stop valve which, when pushed upwards, electromechanically engages the cylinder motor.
  • the table comprising the clamping block, the idler cylinder and the drop sheet, as well as the guide rollers, can be moved from right to left and vice versa by means of horizontal slides. This movement allows the table to follow the progress of the pots when replacing a full pot with an empty pot.
  • a preset meter counter gives a signal which sets in motion both the guide rollers and the articulated table.
  • rollers pushes the full pot to the left and ejects it from the potting pot, while the other roller pushes the empty pot also to the left, so that it replaces the full pot.
  • This empty pot is then under the head of the potter and begins to fill.
  • the wick part which was delivered by the card was deposited along the articulated table which followed this translation, in particular it passed through the clamping block and also passed over the idler cylinder and on the drop sheet.
  • the idler cylinder came to be positioned below the cylinder controlled by an engine and pressed against it by the force of the spring pushing it upwards.
  • the rotation of the controlled cylinder is such that the wick, now pinched between the two cylinders, is driven towards the empty pot.
  • the turns deposited on the articulated table are then unwound and gradually sent to the drop sheet from where they fall into the new pot in progress filling.
  • the wick is also pinched by the clamping block, which retains it.
  • the wick tightens between the two cylinders and the clamping block, then it breaks.
  • FIG. 1 shows the rotating potting head 1, the principle of which is well known. Under this head is the pot 3 which receives the wick. To the left of this pot is a pot 2, which is filled with wick and has just been ejected by the system. To the right of the pot 3 is an empty pot 4, ready to replace the pot 3 when it is full.
  • the horizontal table 5 comprising a clamping block system 6 for retaining the wick and a cylinder 7 for driving the wick.
  • This horizontal table is articulated around a horizontal hinge, not shown, but whose pivot axis is shown at 51.
  • a second pivoting system is shown at 8 and comprises horizontal arms carrying guide rollers 81 and 82 pressing respectively on the pot in service 3 and on the reserve pot 4.
  • the system 8 is articulated around a horizontal hinge not shown , whose pivot axis is shown at 83.
  • the table 5 and the arms 8 can also move from left to right and from right to left on horizontal rails not shown, but whose axes are shown in 51 and 83 respectively.
  • a preset counter When the pot 3 is full, a preset counter provides an electrical signal which starts the sequence.
  • Table 5 and arms 8 move from right to left on their respective rail with axis 51 and 83.
  • the rollers 81 and 82 respectively push the pots 3 and 4 to the left.
  • FIG. 2 it can be seen that, in the translational movement of the table 5, the clamping block 6 has come into contact with a valve 10 fixed to the frame 100 of the machine, but oscillating around an axis 101. This valve rose to let the clamping block 6 pass, then fell back on the rear face, relative to the movement, thereof.
  • FIG. 8 shows the operation of the valve 10.
  • the valve 10 When the upper part of the clamping block 6 has passed under the valve, the latter has been pushed back to the position in dotted lines 102, then, as soon as the movement of the valve block tightening 6 from right to left continued, the valve 10 fell back into position 103. The fall of the valve 10 stops at a point where the distance 104 between the valve 10 and the clamping block 6 is equal to the thickness of the wick (not shown in this figure). The wick is then pinched between the valve 10 and the clamping block 6. This pinching of the wick is shown in FIG. 6.
  • Figure 3 then shows the position of these various organs.
