Definitions
- the invention relates to a support structure for a shedding system of a weaving machine, which has a machine frame with two side parts, between which shedding means are to be attached, for which the support structure contains a system of rods and levers.
- a support structure for a shedding system of a weaving machine of the type mentioned at the outset is known from EP 742 298 B1 or DE 696 07 675 T2.
- the known support structure has a U-shaped profile with side elevations, in which the system of rods and levers is arranged.
- the supporting structure also serves as an oil container.
- the known support structure is voluminous and difficult to implement. It is also not particularly suitable for aligning various components mounted in the support frame or keeping them aligned. Therefore, the known support structure is not particularly favorable for use in weaving machines that work at high weaving speeds.
- the well-known carrying construction limited to a certain drive system and only suitable for use in a weaving machine with a given width.
- the aim of the invention is to provide a support structure of the type mentioned, which does not have the disadvantages mentioned and which is suitable for high weaving speeds.
- a housing composed of at least two partial housings is provided for accommodating the system of rods and levers, of which a first partial housing in the region of the outside of a side part and a second partial housing in the region between the two side parts and transversely to the Side parts is to be arranged.
- the design according to the invention achieves the advantage that the support structure formed from at least two partial housings is sufficiently resistant to changing forces, changing temperatures, deformations, vibrations or resonances and therefore allows weaving at high weaving speeds.
- the supporting structure can be selected in a simple manner depending on the width of the weaving machine or can be adapted to it.
- the first partial housing is provided with fastening means for attachment to a side part of the weaving machine, and that the second partial housing is fastened to the first partial housing.
- the second part of the housing advantageously extends up to the side part of the weaving machine, which lies opposite the side part to which the first part of the housing is attached. This results in a rigid support structure that allows weaving at high weaving speeds.
- the fastening means for attaching the first partial housing to a side part of the weaving machine contain elastic elements. This enables relative movements between the machine frame and the supporting structure, so that oscillations and the like. are transferred less strongly from the supporting structure to the machine frame or from the machine frame to the supporting structure.
- This design of the fastening means is also advantageous when the supporting structure is in one piece and is not assembled from several partial housings.
- the partial housing and the system of rods and levers accommodated therein form a structural unit which can be attached to a weaving machine and can be removed from the weaving machine. Units can be kept ready that differ only in the part housing to be arranged between the side parts of a weaving machine, which is dimensioned according to different weaving machine widths.
- the partial housings are provided with reference surfaces facing each other. By means of these reference surfaces, the partial housings can be positioned exactly with respect to one another while they are attached to one another. This positioning is retained even when the forces and temperatures change.
- a seal is preferably provided between the two reference surfaces. This can prevent oil, especially lubricating oil, from getting between the reference surfaces.
- the second partial housing contains a U-shaped profile which forms a bottom and two side walls of the partial housing.
- a bottom and two side walls of the first partial housing are components of a profile.
- Such a partial housing can be used as an oil serve storage container or as an old passage to the second partial housing, for example formed from a U-shaped profile, which can also be an oil storage container.
- a control lever is mounted in the first partial housing so as to be pivotable about an axis, which is connected on the one hand by means of a coupling system to a drive lever and on the other hand by means of a transmission rod to a shedding device and by means of a connection system to at least one further lever, which is connected in the second Part housing stored and is also connected to the shedding means by means of a transmission rod.
- the reference surface of the first partial housing runs parallel to the axis of the control lever and the reference surface of the second partial housing runs parallel to the axis of the further lever. Because of this arrangement of the reference surfaces, the axis of the control lever and the axis of the further lever can be aligned exactly parallel to one another, so that the control lever and the second lever are aligned with one another. This alignment is retained even when the forces occurring and changes in temperature change.
- the axis of the control lever is mounted in the region of the front end of the first part housing, which is assigned to the second part housing.
- the control lever can be arranged closer to a shedding means, in particular a shaft frame. This makes it easy to connect the shedding device to the control lever.
- This arrangement also makes it possible to install a lubrication system, such as lubricant lines or lubricating oil spray nozzles, in the area of the control lever bearing.
- a lubrication system such as lubricant lines or lubricating oil spray nozzles
- the control lever bearing which is normally subjected to high forces, can be well lubricated.
- the storage arranged in this way the control lever are cooled in an advantageous manner.
- the lubricating oil is preferably used at the same time for cooling the bearing.
- the supporting structure has a third partial housing, which is attached to the first partial housing on the side facing away from the second partial housing.
- the drive lever is stored in the third sub-housing.
- the first partial housing and the third partial housing have reference surfaces facing one another, the reference surface of the first partial housing preferably running parallel to the axis of the control lever and the reference surface of the third partial housing parallel to the axis of the drive lever.
- a seal is preferably provided between the reference surfaces in order to prevent oil, in particular lubricating oil, from getting between the reference surfaces.
- the axes of the control lever and the drive lever are aligned exactly parallel to one another by the reference surfaces, so that the control lever and the drive lever are aligned.
- control lever is connected to the drive lever by means of a clutch system, a clutch rod being rotatably mounted at a first articulation point of the control lever, which is located at the top in the first partial housing, and a clutch rod is connected to the drive lever via an adjustment unit.
- the control lever is preferably connected to the further lever by means of a connecting system, a connecting rod being articulated to a second articulation point of the control lever, this articulation point preferably being located at the bottom in the first partial housing.
- at least one intermediate wall is provided between partial housings, which protrudes upward from the bottom of the respective partial housing.
- the oil, in particular lubricating oil, present in the two adjoining partial housings can be separated from one another.
- the partition is preferably designed as a seal between the partial housings.
- the partial housings are preferably each provided with an intermediate wall. This makes it possible to separate and remove the sub-housings from one another without oil being able to leak out of the sub-housings.
- pressure oil supply lines are led to one or more of the axes arranged in the partial housings.
- the axes which are provided with outlet openings in the area of the bearings, then serve as an internal supply line of lubricating oil to the bearings.
- the lubricating oil supplied to the bearings can drip into the partial housing.
- oil is guided from the axles, which are provided with outlet openings for pressure oil, by means of pressure oil channels running through the rods and levers to articulation points which connect the rods and levers to one another.
- brackets for guides for the up and down movable compartment forming means are arranged on the second partial housing to be arranged between the side parts of a weaving machine.
- the shedding system is designed to form an assembly that is largely independent of the machine frame of the weaving machine.
