BATHROOM CIa

In operating such a reciprocating mechanism for a winding machine is used to turn the troaael over its longitudinal axis, and the part of the reciprocating member engaging in the groove travels along the mock groove, which two screw threads Includes parts, the direction of movement being instantaneously at each end of the crouching trοοβθΙ uat an angle equal to twice The guide angle of each helix at this point changes and a part of the limb that is in contact with the rail goes over the stationary one Rail or several such rails slides.

In the case of the desired increased productivity for winding machines, along with the correspondingly increased cam speed, the forces acting on the reciprocating link and its acceleration at each end of the troaael where the link changes direction are increased.

To facilitate such a change in direction of the limb and To reduce the loads acting on the reciprocating mechanism, it is favorable if the limb is so light in weight and AbBeesungSBäsaig is as small as it is attractive. Soait must be with the Design of a reciprocating link for a yarn winding machine the amount of potential loads acting on the oil to be taken into account «which are still available for an operation in the desired Way are permissible. For this reason, the limb should be as small as possible.

So it is essential that the part resting against the rail

the limb can easily slide into its two Qleitetellungen. The part of the limb that is in contact with the groove is smooth in dtr Can run the cam groove.

The purpose of the present invention is to provide a back and forth going links., which for a special winding machine opposite bokknow the limbs going back and forth YerhKltniseXeeig little ones

Another purpose of the invention is to provide a reciprocating Glladee for winding machines, nrelches a content sharing one The fascines work at relatively high speeds enr. possible.

The problems explained above are achieved at a yarn winding machine is a “one going back and forth” Member having crouching section, a rail section, which slides over at least one fixed rail, an intermediate spacer and a yarn guide section in the neecuitliohen by the fact that the distance is a tight fit between the fixed rail and the cam profile forms and has the shape of a tangent to the drum. if thus the axial length of the limb is considered is negligible the arrangement made, the length of the Nockenanlageabscbnittes almost equal to the depth of the cam groove, the length of the spacer section is equal to the distance between the Hockentronael and the stationary one Rail, and the length of the section adjacent to the rail

iet equal to the width of the rail * In such an arrangement it lays the barrel cam positively feat the reciprocating member in a radial direction relative to the axis of rotation of the barrel the spacer section ensures that the part of the link resting against the cam and the part resting against the rail Show the lowest possible blowdowns in accordance with the task to be performed.

Thus there are on the cam and the part resting on the rail the reciprocating member is not required, over the reciprocating member in the radial direction with respect to the axis of rotation to fix the cam drumel in place. The latter section serves only to locate the limb in a direction perpendicular to this radial sighting, consequently the link is positively prevented from sliding in a straight line direction only. The surfaces of the spacing, which in parallel planes at right angles to the one extending radially Running direction, lie against the rail or rails or against the drum «So there is no need for these Surfaces on those resting on the rail or on the cam Provide sections of the limb so that these «sections are smaller can be carried out as state-of-the-art technology.

The limb moving back and forth is appropriately prevented from to slide between two parallel and fixed rails. Per at the The splint adjacent to the limb is generally in plan view rhoaboid-like, which means that the section is bit two

A reciprocating mechanism 10 for the Oarnquerführung a erfindungsgesäseen winding machine for the production of cylindrical Winding comprises a profiled cam drum 12 with a continuous Groove 15 in the cylindrical surface of the drum. The drum is in a housing 1 ^ f rotatably mounted and runs with its Ittngsachse parallel to and slightly above the axis of a holder for a roll 15, which is to be produced by the winding machine.

The housing 1 * t has a slot 16 running in the longitudinal direction next to the winding 15. Metal rails 17, 18 are attached to the housing Ik along each edge of the slot 16. The distance between the two teas 17 «18 is such that the effective width of the slot 16 is reduced. A reciprocating member 19 made of molded plastic material, generally cross-shaped in plan view, can slide with a rail contact section 20 between the rails 17 »18, with a cam contact section 21 engaging in the socket 13.

There-. Link 19 is held in groove 13 by singing handle and because of the helical shape of the groove 13 between the two rails 1 ?, 18 moves back and forth at constant gas speed, the turning point this movement corresponds to the reversal points of the groove 13

At the outermost part of each screw part of the groove 13, the

which is cut into a radially extending tab which is formed in one piece with the rail contact component 20 of the link 19. The groove Zk is arranged in such a way that it receives the yarn 25 in its essentially vertical path 25 and guides it to the lap 15 to be produced. A reciprocating movement of the link 19 causes the yarn 15 to be guided transversely along the changing pad.

The yarn transverse guide 23 and the sections 2O ₁ 21 of the cam follower are ßoait in the form of a back and forth movable member of uniform construction, with no need to attach a pin within the arrangement. Therefore, the reciprocating member 19 is designed to be as small as possible in terms of dimensions and weight. The loads applied to the reciprocating mechanism 10 are kept at a relatively low level.

common axis of symmetry is present. When the water supply section 21 is rotated in opposite directions at each end of the cam barrel 12, the rail abutment portion 21 is rotated around a horizontal axis through its center by an equal amount. Accordingly, the rail system part 20 has two actuatable ones Slider sections up and is rotated between these positions at the extreme limits of its reciprocating motion. This Section 20 has two pairs of opposite sides when formed in rhomboid form Areas that form the rhomboid. A pair of the surfaces strike against the rails 1 ?, 18 in each actuatable Sliding division on. The angle of inclination between the two rail contact surfaces on one side of the longitudinal axis of section 20 is equal to twice the guide angle of each helical part of the hat at their other ends.

In a modified embodiment of the invention, the rail system part 20 of the reciprocating member 19 may be cylindrical, this Toil between two operational sliding positions on the The reciprocal points of the reciprocating motion can oscillate, and i; was rhomboid shaped in the same way as the one described above Rail system part.

Slides easily like the rails 17-18 and in the required position Way at every transverse turning point.

The sliding action of the reciprocating member 19 is facilitated by introducing a shell liquid, for example mineral oil, into the cam drum housing 1 * f. In the case of a formation forum, the drum 12 is just dipping into a supply which the oil forms in the base part of the housing Ik . Therefore, the drum 12 takes some oil with it, part of which is deflected by a guide member 26 attached to the periphery of the drum 12 into a longitudinally continuous, vertically extending passage 27 which runs through the center of the upper rail 17 . In this way oil is distributed like the parts moving relative to each other, ie between the mock groove 13 in the drum 12 and the reciprocating link 19 and between the rails 17t 18 and the link 19.

The oil runs into its sump, and a splash guard 28 is on the Rails 17, 18 fastened to the possibility of occurrence of To prevent oil leakage on the winding to be produced 1 * t · The gap in this splash guard 29 corresponds exactly to the narrow strip, which dirch them over. moving movement of the GamfUhrung 23 coated w'.id- S3 that? the yarn path is not restricted.
