Definitions

  • the invention relates to a device for transferring crockery elements from a conveyor in a drawing machine for warp threads on supporting elements of a weaving machine, with an ejector to remove the dishes from the Conveying member.
  • Such a device is already known from EP 0 500 848, in which the support members designed as support rails have an inclined, downward inlet flank. Ejectors push the crockery elements from a support pins Conveyor on top of these inlet flanks so that the Crockery elements along these inlet flanks on the mounting rails slide.
  • the mounting or support of the mounting rails against gravity is done by retractable and extendable Retaining bolts that are attached to a transport system are. Position them in their retracted position Holding bolts the mounting rails. For passing the dishes the retaining bolts are extended at the relevant point.
  • a disadvantage of the known device mentioned is therein to see that to pass the dishes, the guide or support of the mounting rails temporarily then is removed when the dishes element from the support pins of the funding body passes to the mounting rail. So that will precise alignment of the support pins and support rails is endangered. This unfavorable circumstance can be mitigated be that the mentioned guidance of the mounting rails if possible is located far from the funding body. But the exact alignment of the support pins and the Carrier rails impaired.
  • the invention as characterized in the claims is therefore the task of closing a device create, in which the supporting elements at the moment of delivery of the crockery elements aligned as precisely as possible are.
  • the guide roller has a recess that extends from the circumference towards the axis and serves, on the one hand, space for the passage through the end loops of the tableware elements and on the other hand a target for the forward movement of the Tableware elements on the support member by the guide roller to accomplish.
  • the guide roller with the recess forms a lock for the dishes.
  • the advantages achieved by the invention are particular to see that at the moment of handing over the dishes from the funding body, the support body exactly and clearly is guided, the guide for the passage of the dishes is only partially canceled when that Tableware element is already taken up by the support member. there the support elements are always laterally through the guide roller, in every position of the guide roller.
  • Another The advantage is that the guide roller is a simple one Performs rotary motion and at the same time propulsion who performs dishes over a distance.
  • the guide roller can be used for any number of neighboring supporting elements be interpreted. During the advance of a single tableware element due to the guide roller, it also holds already transported dishes, so that these are not pushed against the funding body again can.
  • Fig. 1 shows a section through part of a guide roller 1 for several supporting elements 2, 3, 4, which are at equal intervals are arranged side by side.
  • the guide roller 1 is on a shaft 5 about an axis 6 in a not shown, but rotatably mounted in a known manner and connected to a drive 7.
  • the guide roller 1 has lateral guides 8, 9 for guiding the support members 4 in Direction of an arrow 10 and guides 11 for guidance in Direction of an arrow 12 and thus for guiding in two orthogonal Directions on.
  • the guides 8, 9 are in the area a recess 13 interrupted or expanded and form therefore not a closed circular ring.
  • a tableware element 14 drawn on the support member 4.
  • In one, through an arc 15 delimited area is a section through the guide roller 1, which in turn is in the region of the guides 8, 9, 11 lies, but with the support member 2, through these guides 8, 9, 11 is shown.
  • Fig. 2 shows the support member again on an enlarged scale 2 with the guides 8, 9, 11 of the guide roller 1.
  • Fig. 3 shows the arrangement of the from a different angle Guide rollers in or in front of a warp threading machine. Since the tableware elements shown here schematically 16 each have an eyelet 17, 18 at the top and bottom are as Support member also two support rails 19, 20 are provided.
  • the drawing machine points as part of a funding body 21, 21 'for each harness element has two retaining bolts 22, 23, one of which a plurality next to each other, for example on a rotating one Chain are arranged, such as this from is already known from EP 0 500 848.
  • the drawing machine preferably also has two ejectors 24, 25 on, here once in the starting position 26, 27 and are shown in the end position 28, 29. These are in able to move from the starting position into the End position.
  • ejectors 24, 25 are but known per se and therefore their drive is not described in more detail.
  • To each mounting rail 19, 20 is also a guide roller 30, 31 is provided. These are cut here shown, the section running in one plane, as shown in FIG. 1 by a broken line 32 is shown and in principle by the center of the dishes goes. So that of the recess 13 (Fig. 1) corresponding recess 33, 33 'clearly visible, which is from Circumference 34, 34 'extends against axis 35.
  • the recess 33 causes that of the guide 11 (Fig. 1) corresponding guide 36 is about three quarters of the circumference extends. For the side guides 37, 38, the this corresponds to the guides 8, 9 (FIG. 1) greater.
  • the guide roller is very close to the end 46, 47 of the Support rails 19, 20 or the support member and to the conveyor 21, 21 'arranged adjacent.
  • Fig. 4 again shows the same elements as Fig. 3. Therefore they are also provided with the same reference numbers. Indeed have the guide rollers 30, 31 and the dish element 16 took another position.
  • the tableware element 16 is through guide surfaces 39, 40, in the recesses 33, 33 'detected and moved on the mounting rails 19, 20 Service.
  • the ejectors 24, 25 are still in their end positions 28, 29.
  • FIG. 5 again shows the same elements as FIG. 3.
  • the tableware element 16 is conveyed on again shown.
  • a crockery element 16 such as a braid or The slat is moved by synchronously rotating conveying elements 21, 21 ' on two retaining bolts 22, 23 in a manner known per se the mounting rails 19, 20 out. Then the ejectors move 24, 25 from the starting positions 26, 27 to the end positions 28, 29, the end loops 17, 18 of the tableware element 16 of the retaining bolts 22, 23 in the direction of an arrow 45 stripped and pushed onto the mounting rails 19, 20 become. During this time, the mounting rails are 19, 20 on the one hand through the guides 37, 38, 37 ', 38' laterally and the guide 36, 36 'in the vertical direction. Then the tableware element 16 through the guide rollers 30, 31 detected in the direction of arrows 41, 42 turn.
  • the rotation of the guide roller can be both continuous be targeted or by control and monitoring elements to be controlled. With continuous movement due to the location of the recesses 13, 33 periods released, in which the ejectors 24, 25 the tableware element 16 can eject.
  • the movement of the guide roller can but also aim at the conveyor 21 so that the guide roller 3 waits until the Ejectors 24, 25 have done their job. Then do as quickly as one full turn to get back into the 3 position.
  • the guide roller can driven by a DC motor or a stepper motor become. Appropriate are to monitor the position Provide encoder.
  • the drive is 7 effectively coordinated with the drive of the ejectors 24, 25, as can be seen from the described mode of action.
