Description

1 2710658

  The invention relates to an installation for sharing a first machine between at least two machines which, in the production line of a product, must be adjoining

  at the first machine approximately along a joint plane.

  It applies more particularly, but not exclusively, to textile machines such as a first machine producing a textile wick between at least two machines consuming it, such as different reeling devices. In the textile field, it is known to condition the textile wicks obtained after treatment of the wool in two

different conditionings.

  For this purpose, use is made in particular of: either a device for depositing the wick in a pot, this device generally known by the term "coiling" depositing the spiral wick in successive layers in a pot rotated, or a winder implementing a kernel around

from which the wick is wound.

  Currently, these two types of winding devices are used to meet the specific demands of users. It is therefore necessary to provide in the wool combing chains both chains provided with one of the two types of winding devices and chains provided with the other device but generally this demand is not sufficient for the devices to both types operate at the same time and, more generally, the devices

  winding are used alternately.

  To feed these winding devices with a textile wick, use is made of a feeding device or "gill" which is placed upstream of the winding device

  chosen and downstream of a carding machine.

  This feeding device must be positioned precisely with respect to the winding device to avoid unnecessary stresses in the wick which would modify the characteristics of this wick, in particular its weight.

  linear and could break it.

2 2710658

  These feeding devices are heavy machines

  of the order of three tons and are relatively bulky.

  In addition to their own members, these also provide motive power to at least some of the downstream winding device members to which it transmits its movement through a mechanical coupling which is substantially different from a type. from one wrapping device to another but without being totally incompatible because these feeding machines must originally be able to equip both types of winding devices. So far, there are provided as many feed devices also called "gills" that winding devices. It is understood that the sequential use of these feed devices has repercussions on the cost price

some products.

  Also, when a power device is down, it can not be easily replaced by another one that

  would possibly be in reserve the time to repair.

  To remedy this situation, there are known facilities provided with means for sharing the device.

  feeding between two different winding devices.

  These means consist essentially of rolling members: equipping a frame, - supporting the feed device, cooperating with running rails anchored to the ground, - for guiding the feed device in its movement and to ensure its positioning accurate in front

  the winding device for which it is intended.

  In this solution, it is the running gear and the running rails which, essentially, can contribute to the strict positioning of the feed machine but, because of the precision required for this positioning, these infrastructures are expensive all the more that besides

  rails, it is also necessary to provide switches.

3 2710658

  In order not to create obstacles to the circulation of other vehicles or persons on the ground, the rails are buried but, as a result, the particulate materials accumulate on these rails and make the movement of the device rapidly difficult. Another disadvantage is that it is not easy to build these rails in an existing installation where this data has not been taken into account to stop the layout

machines, pillars, etc ...

  One of the results that the invention aims to obtain is an installation of the type mentioned above which remedies the

aforementioned drawbacks.

  For this purpose, it relates to such an installation for sharing a first machine between at least two machines such as a textile machine supply device and retractor devices comprising means for moving the first machine between the two. others and ensure their positioning, this machine being characterized in particular that the means for moving the single machine comprise levitation means of said single machine and, firstly, each machine between which the single machine is shared has a fraction similar to a translation guide means and, secondly, the shared machine carries a complementary fraction of the guide means, these guide means being designed to act only when the complementary fractions

  are close to each other.

  The invention will be well understood with the help of the description

  BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a non-limiting example with reference to the appended drawing, which schematically represents: FIG. 1: a top view of a production line, FIG. sharing installation, - figure 3: a view of a detail of a sharing installation. Referring to the drawing, we see that, in chains of a manufacturing unit, such combing lines of

4 2710658

  at least two machines 1a, 1b fulfilling similar functions such as winding devices of different types and in particular dispensing devices by

  gravity of turns and winders.

  Attached to each of these two machines la, lb similar in their function, for example that upstream, is provided an identical machine 2 as a device 2 for supplying wick of the winding device, these machines upstream 2 and downstream the , lb being associated with each other approximately along a joint plane J by various members such as a conduit for guiding the wick to the winding device and means for

  synchronization of their movements.

  For example, these feeders supply motive power to the downstream winding device to which they transmit their motion through a

mechanical coupling.

  Conventionally, to share a single machine such as a feed device 2 between at least two machines la, lb such winding devices including different types, the unit includes a sharing facility

  provided with means 3 for moving the single machine.

  According to the invention, the means 3 for moving the single machine 2 comprise means 4 for supporting said single machine and, on the one hand, each machine 1a, 1b between which the single machine 2 is shared has a similar fraction 5a. a translational guiding means 5 and, on the other hand, the shared machine 2 carries a complementary fraction b of the guiding means 5, these guiding means being designed to act only when the fractions 5a, 5b

  complementary are close to each other.

  This allows to move on any course and without real limitation the unique machine that is guided only

  in the terminal phase of his transition course.

  According to the invention, the so-called proximity guiding means 5 comprise, for one of the fractions, two so-called reference faces 6 which perpendicular to the joint plane J are spaced from each other by a predetermined fixed distance D

2710658

  and for the other fraction, two so-called positioning surfaces 7 which, mobile with respect to reference points of the machine to which they are associated, can be spaced apart by a distance equivalent to the fixed distance D mentioned above in order to take support on the reference faces 6 to position transversely the machines one

compared to each other.

  According to the invention, the positioning surfaces 7 are

  formed by cams 8, for example, eccentric.

  According to the invention, it is the machines 1a, 1b between which the other single machine 2 is shared which carry the

positioning surfaces 7.

  In an alternative embodiment (not shown), these are the machines between which the single machine is shared

  which carry the reference surfaces.

  In a preferred embodiment, the reference faces 6 are made by the opposite faces of two

  9 longitudinal members spaced apart from each other.

  Preferably, at the ends 9a of the longitudinal members 9, these opposite faces are connected with ramps 10 facilitating their

  engagement between the positioning faces.

  According to the invention, each of these machines comprises stopping abutments 11 and the shared machine carries abutments 12 of depth which, by cooperating with the abutment stops 11, make it possible to position the front face 13 of the shared machine 2 exactly, to the running games near, in the

  joint plane of each of the two machines.

  Advantageously, the rear end 14 of the shared machine comprises a locking means co-operating at least indirectly with an anchoring point 16, which is placed in such a way that, when the locking means is made active, it maintains with the guiding means the machine

unique in the joint plane.

  According to the invention, in the case where the reference faces are carried by separate longitudinal members, the space 17 located between the two positioning faces is at least partially closed by a plate 17a to avoid any bad engagement

  struts between the positioning faces.

  Of course, the plate 17a could be mounted on the

fixed machines.

  In one embodiment, the levitation means 4 are air cushion devices 4 cooperating with a frame 18 carrying the shared machine. These provisions make it easy to move the shared machine without the need to provide ground infrastructure. It is therefore very easy to circumvent all possible

obstacles.

  In the extreme case where the bare ground is in too bad condition for normal operation of the air cushions, it suffices to

  temporarily deposit on it a waterproof film.

  The chassis carries at least one belt 30 in which, during the pressurization of the air cushion device, this

device comes to position itself.

  In a preferred embodiment, the frame 18 is provided with feet 19 of sufficient height to place the lower edge of the frame and possibly the belt at a level at least slightly greater above the air cushion device after depression and thus, after displacement of the shared machine and depression of the air cushion, allow the removal of the levitation means which are, for example,

  simply engaged under the frame in the manner of a drawer.

  They can thus be used for moving a

other machine.

  In an alternative embodiment, the frame 18 of the shared machine is provided with adjustment means 21 in height

of the device relative to the ground.

  Regardless of these means of adjustment in height, the fixed machines may also include means of

height adjustment.

  According to the invention, the parts of the similar machine and of the shared machine coming opposite are, for at least one of them, provided with a quick connection interface 22 allowing the couplings to be mechanical and / or electrical necessary between them suitable whatever

  those of similar machines.
