Description

-D E S C R I P T I 0 N-

  The present invention relates to a wholesale spinner comprising fins mounted in at least one row on a

  finned bench, as well as a device designed to replace it

  automatic bench reels full by empty preparation reels, and taking the form of a succession of

  hanging carts which can be moved on guide ways

  dage, consists of several trolleys connected to each other

  others by joints, and is provided with suspension supports

  board in which the bench reels and the preparation reels can be suspended following lifting movements of a spinner device, carrying respectively

coils or bobbins.

  The prior art has already proposed, for coils of wire

  lage, a conveying device (DE-A1-39 22 084) which comprises

  running rails in which successions of cha-

  riots move on pairs of rollers. The coils of

  wiring to be conveyed are suspended in a loose manner

  maple, to these successions of carts. The suspension and the pre-

  are insured by means of coupling parts

is lying.

  In this known device, the full bench coils or

  empty prep coils can, respectively,

  complete a disadvantageous oscillation in relation to their position

  tion suspended, so that it takes a certain time to be able, in a functionally reliable manner, to

removing the coils.

  We also know in the prior art (CH-A5-

  679 596), a hanging conveyor in which load carriers are provided on which articulation bodies

  of bench are suspended. The same disadvantageous effect results.

geux than that described above.

  The present invention therefore relates to a

  structural arrangement of the type mentioned in the introduction, perfect

  to be able to contribute in a simple way to a rac-

  shortening of the removal time and a reduction in the height of realization. According to the invention, this object is achieved by the fact that the bench reels and the preparation reels are received on suspension supports which prevent, or limit

  at least strongly their transverse pendulum movement

  relative to the direction of movement of the estate

of hanging carts.

  The advantage thus provided consists in that it is re-

  attached, in accordance with the invention, to the oscillating articulation known per se and integrated in the suspension support,

  which has the effect of significantly reducing the height of realization

  tion. Correspondingly, the coils and coils cannot

  no longer perform a pendulum motion, as before

  sent, which offers a considerable advantage for the application case

  cation accompanied by high speeds of successions of suspended trolleys, high demands placed on precision

  positioning, and the search for short cy-

keys at the replacement stage.

  According to the invention, a pendulum movement

  in the transverse direction can be prohibited in all cases.

  A pendulum movement, in the direction of movement of the succession of suspended carriages, may be prohibited when the

  movement takes place only horizontally, or else

  that an oblique position of the coils or bobbins is admissible when the succession of suspended carriages crosses a slope

ascending or descending.

  Suspension supports of known type have, in the lower region, a reel trap for retaining the reels and, in the upper region, a threaded rod for attachment to the reel rack or a hanging carriage. These

  two parts are joined, in a manner known by it-

  even, by means of a ball joint allowing movement

  universal pendulum of the coil. However, the sup-

  suspension ports are by themselves of rigid construction and are permanently locked in the suspended carriage or are, at most, mounted to oscillate in the direction of movement of the suspended carriage. The invention will now be described in more detail, by way of non-limiting examples, with reference to the appended drawing in which: FIG. 1 is a side elevation of part of a succession of hanging carriages, with fragmentary illustration a running rail; Figure 2 is a side elevation of a first embodiment of the invention; Figure 3 is a side elevation, partially in section, of another embodiment of the invention;

  Figure 4 shows the application of the embodiment

  tion according to Figure 3, in the presence of a suspended carriage; and Figure 5 is a side elevation, partially in

  section, of a third embodiment of the invention.

  Figure 1 illustrates schematically, in elevation la-

  part, of a succession 1 of hanging carts.

  This succession 1 consists of a number of suspended carriages 2 respectively connected to each other by joints 3 known in themselves. The joints 3 consist essentially, respectively, of a support 4 of

  on either side of which rollers 5 are arranged, moves

  erasing in a running rail 6. In addition, each support 4 pre-

  feel guiding rollers 7 and 8 for longitudi guidance-

nal in the running track 6.

  The individual hanging trolleys 2 are equipped with suspension supports 9 to which, in a manner known per se, bench coils 10 conforming to FIG. 2 or preparation coils 11 conforming to FIG. 1 can be suspended respectively. In this case, the suspension of the coils

  and coils 11 to the supports 9, and the fixing of said supports

  ports on suspended carts, are made to prevent,

  or at least strongly limit the pendulum movement desi-

  your coils and said coils transversely to

  the direction of movement of the succession of 1 carriages above

  hanged. The fact that common type suspension supports are provided in any case with a ball joint for the oscillating retention of coils and coils, the difference,

  between the outside diameter of the suspension support and the diameter

  inner meter of the bobbin, is certainly large in sup-

  ports of this kind and typically reaches up to 10 mm. In

  presence of a suspension support made rigid and / or ver-

  permanently rusted, in accordance with the invention, this large diametrical difference would imply that the coils and bobbins could, nevertheless, accomplish a pendular movement of a notable stroke. To remedy this, it would also be advisable for

  the aforementioned diametral difference is, respectively, reduced

  or chosen from a low value, to the extent authorized by an unhindered introduction of the suspension support into the coils. This can be obtained by increasing the outside diameter of the suspension support, or by reducing the inside diameter of the bobbin in the area in which it is,

  respectively, fitted or threaded on said support.

  In the embodiment according to FIGS. 1 and 2, the suspension supports 9 are of rigid construction and are

  permanently locked, in the hanging trolley 2, via the

  medial of bolts 20. Correspondingly, the supports 9 or, respectively, the bench coils 10 according to FIG. 2, which are fixed thereto, also occupy an oblique position when the succession 1 of suspended carriages traverses a

  upward slope with 2 individual hanging trolleys.

  In this case, the position is deliberately taken into account

  oblique coils or bobbins when the succession 1 of cha-

  hanging riots travels upward or downward, more specifically, to promote a ban

total pendulum movement.

  In the embodiment according to Figure 3, the sup-

  suspension ports 9 which are similarly rigid in their own right, are pivotally mounted in the carriage

  suspended 2, around a respective axis 12 oriented transversely-

  ment relative to the direction of movement of the succession 1 of hanging carriages. Each individual carriage 2 comprises for this purpose, in the lower region, a recess 15 in order to authorize a possible pendulum movement in the respective direction of movement of the succession of carriages 1 or individual carriages 2. Thus, Figures 3 and 4 illustrate

  rigid suspension supports 9, pivotally mounted in the chain

  suspended riot, so that a bench reel 10 fixed to the support

  suspension 9 can take, for example, a suspended position

due vertically down.

  The exemplary embodiment according to FIG. 5 comprises a suspension support 9 articulated and permanently locked in the suspended carriage 2, a joint 13 being respectively

  provided outside the region of said carriage 2. This articulation

  tion 13 is structurally organized in such a way that its pivot axis is oriented transversely to

  the respective direction of movement of succession 1 of each

  riots, or 2 individual carts. This, too, has the effect of

  fet to prohibit in all cases a pendulum movement in the transverse direction, a pendulum movement in the direction

  movement is however possible.

  The present invention makes it possible, in a simple manner, to

  take precedence over the oscillating joint integrated in the suspension support, so that the height of the latter

  is clearly reduced. In addition, the bobbins and bobi-

  can no longer perform a pendulum movement as ac-

  centered, transversely to the direction of movement

  ment of the succession of hanging carts, which gives a

  improved positioning accuracy and shortened

  shortening of the duration of cycles at the replacement stage.

  It goes without saying that many modifications can be made to the spinner described and shown, without going out

of the scope of the invention.
