Description

Frame for a Weaving Machine and Weaving Machine with a Frame
TECHNICAL FIELD AND PRIOR ART
The invention relates to a frame for a weaving machine comprising a mounting bar arranged above a fabric area, which mounting bar is configured so that weaving machine devices can be fixed thereto. The invention further relates to a weaving machine comprising a frame.
It is generally known to provide a frame of a weaving machine with a mounting bar, which mounting bar is configured so that weaving machine devices can be fixed thereto. Weaving machine devices to be fixed to the mounting bar include, but are not limited to, harness guides, a selvedge device, a pick repair device, an air supply device, a lamp, and others.
The mounting bar is arranged above the fabric area. In the context of the application, the fabric area is defined as an area of a woven fabric and of warp threads neighboring a beat-up line, wherein a section of the fabric, which section extends between the warp threads and a fabric take-up system, and a section of the warp threads, which section extends from the beat-up line, are arranged in the fabric area. The mounting bar is arranged above the fabric area and in a height direction higher than the fabric take-up system.
Known mounting bars have a rectangular cross-section. The weaving machine devices are attached to the mounting bar using rectangular sleeves that are fitted onto the mounting bar and secured to the mounting bar at a desired width position of the frame.
SUMMARY OF THE INVENTION
It is an object of the invention to provide a frame for a weaving machine with a mounting bar that allows for a higher degree of flexibility for attaching weaving machine devices to the frame. It is a further object of the invention to provide a weaving machine with such a frame.
These objects are solved by the frame and the weaving machine with the features of claims 1 and 14. Preferred embodiments are defined in the dependent claims.
According to a first aspect, a frame for a weaving machine comprising a mounting bar arranged above a fabric area, is provided, wherein the mounting bar is configured so that weaving machine devices can be fixed thereto, and wherein the mounting bar is a longitudinal profile having a longitudinal groove at its periphery.
Throughout this specification and the following claims, the indefinite article "a" or "an" means "one or more". In particular, the longitudinal profile in embodiments is provided with more than one longitudinal groove. In addition, throughout this specification and the following claims, the expressions “first” and “second” are only used to distinguish one element from another element and not to indicate any order of the elements.
The mounting bar forms part of the frame for the weaving machine. The frame in embodiments further comprises two side parts and a cross beam connecting the two side parts to each other.
The mounting bar in the form of a longitudinal profile having a longitudinal groove allows a fixation element to engage the longitudinal profile for fixing a weaving machine device to the longitudinal profile without the necessity that the fixation element surrounds the mounting bar.
In an embodiment, the longitudinal profile is provided on at least two sides with a longitudinal groove. The two longitudinal grooves allow that a fixation element for attaching the longitudinal profile to a side part of the frame and/or for fixing a weaving machine device to the longitudinal profile can clamp the longitudinal profile with a form fit. Thereby a need for an additional machining of the longitudinal profile for providing through holes or similar elements in order to attach the longitudinal profile to the side part and/or in order to fix a weaving machine device to the longitudinal profile can be dispensed with.
The fixation element in an embodiment is an arc-shaped or U-shaped bracket having inwardly pointed tips engaging the longitudinal grooves. In other embodiments, the fixation element has a dovetail-shaped groove bordered by two fingers that can engage two longitudinal grooves provided at two distinct sides of the longitudinal profile. In still another embodiment, the fixation element comprises jaws engaging the longitudinal grooves.
In an embodiment, the longitudinal profile has a first side and a second side, which second side is not immediately adjacent the first side, wherein each of the first side and the second side is bordered at opposite edges by two longitudinal grooves, so that two weaving machine devices can be fixed to the longitudinal profile at the same width position of the frame, using a first fixation element that clamps a first weaving machine device to the longitudinal profile with a form fit at the first side of the longitudinal profile and a second fixation element that clamps a second weaving machine device to the longitudinal profile with a form fit at the second side of the longitudinal profile.
The weaving machine devices arranged at the first side and the second side can each be shifted into a desired position along the longitudinal profile, wherein - if not restricted by the size or shape of the weaving machine devices itself - the weaving machine devices can pass each other and/or a support for attaching the longitudinal profile to a side part of the frame. Hence, each weaving machine device can be repositioned without the necessity of dismounting this weaving machine device and/or any other weaving machine device.
In an embodiment, the longitudinal profile is double T-shaped or H-shaped in cross-section, wherein the second side is arranged opposite the first side, and the first side and the second side are bordered at the opposite edges by common longitudinal grooves extending between the first side and the second side.
In another embodiment, the longitudinal profile is a tubular profile having a polygonal crosssection with at least four sides. A tubular profile has a high rigidity allowing a precise mounting of the weaving machine devices.
In particular, in an embodiment, the longitudinal profile is a tubular profile having a rectangular cross-section, wherein the second side is opposite the first side. In an embodiment, the tubular profile is formed by extrusion. In other embodiments, a tubular profile having a rectangular crosssection with flat surfaces is machine finished, for example using roll forming, for forming a longitudinal groove in at least one of the flat surfaces.
In an embodiment, the rectangular cross-section of the longitudinal profile has two long sides and two short sides, wherein the first side and the second side are the two long sides or wherein the first side and the second side are the two short sides. The respective other sides in embodiments can be provided with a smooth surface. In an embodiment, one of the two long sides faces to a front of the frame and the other of the two long sides faces to a back of the frame, and one of the two short sides faces up and the other of the two short sides faces down.
In an embodiment, each of the long sides and/or each of the short sides is bordered at opposite edges by longitudinal grooves. This allows that fixation elements having inwardly pointing tips can be clamped to each of the long sides or can be clamped to each of the short sides. Preferably, each of the four sides of the tubular profile having a rectangular cross-section is provided with at least one longitudinal groove. This allows for a high degree of flexibility for attaching different weaving machine devices to the mounting bar.
In an embodiment, the short sides are each provided with exactly one longitudinal groove bordering the opposite edges of both long sides. This allows for a larger longitudinal groove on the short sides without the necessity of increasing the size of the profile.
In an embodiment, at least one of the longitudinal grooves at the short sides is adapted for receiving an elongated flexible element, such as a cable, a hose, a flexible pipe, a tube and/or a duct. Hence, the elongated flexible element can be securely guided using the mounting bar and the number of unsecured or loose elongated flexible elements at the weaving machine can be reduced.
In an embodiment, the longitudinal profile is tubular and is adapted to serve as a conduit for a fluid. For this purpose, end faces of the profile are closed against the ambient and through holes in a side wall of the profile are omitted and/or sealed off. By using the longitudinal profile as a conduit for a fluid, the fluid can be transmitted from one side of the frame to the opposite side of the frame.
The fluid in an embodiment is air used in a blowing system for removing process dust from the fabric area, in particular from a fabric and/or warp threads. In the context of the application, the expression process dust is used to describe the dust, fluffs and/or thread ends generated or caused in a weaving process. In an embodiment, blowing nozzles are provided, which are fixed to the tubular profile serving as a conduit for the fluid and fluidly connected to the interior of the tubular profile. In an embodiment, a side, in particular a front side, of the tubular profile is provided with a longitudinal recess, wherein a number of connection openings is provided in the longitudinal recess to which connection openings the blowing nozzles can be attached, wherein unused connection openings are sealed using a sealing. The longitudinal recess and the sealing are sized such that the sealing does not or only marginally protrude from the front side of the tubular profile, so that other devices can be shifted across sealed off connection openings.
In an embodiment, the longitudinal profile is a beam having a vertical web and two horizontal flanges provided at opposite ends of the vertical web, wherein the horizontal flanges are each provided with a longitudinal groove. In an embodiment, the frame comprises a first side part and a second side part, wherein the longitudinal profile is attached to the first side part via a first support and/or attached to the second side part via a second support.
In an embodiment, the frame comprises a first side part and a second side part and comprises two longitudinal profiles, wherein a first longitudinal profile is attached to the first side part via a first support and a second longitudinal profile is attached to the second side part via a second support. Such a frame is in particular suitable for use with a jacquard weaving machine, wherein the two shorter longitudinal profiles do not block or at least essentially do no block a visibility of harness wires of the jacquard weaving machine. Such a frame is also suitable for use with a weaving machine, wherein another device is arranged above the fabric area between the first side part and the second side part, for example a jacquarette. Preferably both profiles are identical in design and are mounted to the side parts so as to be shiftable in a width direction of the frame for adapting a position of the profiles to a width of a fabric to be woven.
According to a second aspect, a weaving machine comprising a frame with a mounting bar arranged above a fabric area is provided, wherein the mounting bar is configured so that weaving machine devices can be fixed thereto, and wherein the mounting bar is a longitudinal profile having a longitudinal groove at its periphery. The weaving machine can be a rapier weaving machine or an airjet weaving machine.

Fig. 4 shows a cross-sectional view of the longitudinal profile 11 of Figs. 1 to 3. As shown in Fig. 4, the longitudinal profile 11 has several longitudinal grooves 45, 46, 47, 48. More particular, in the embodiment shown, the first side 41 is provided with two longitudinal grooves 45, the second side 42 is provided with two longitudinal grooves 46, the third side 43 is provided with one longitudinal groove 47 and the fourth side 44 is provided with one longitudinal groove 48. The one longitudinal groove 47, 48 provided at each of the third side 43 and the fourth side 44 in the embodiment shown is larger than the two longitudinal grooves 45, 46 provided at the first side 41 and the second side 42.
Hence, each of the first side 41 and the second side 42 is bordered at opposite edges by the longitudinal groove 47 provided at the third side 43 and by the longitudinal groove 48 provided at the fourth side 44. In addition, each of the third side 43 and the fourth side 44 is bordered at opposite edges by one of the two longitudinal grooves 45 provided at the first side 41 and by one of the two longitudinal grooves 46 provided at the second side 42.
As will be explained in more detail below with reference to Figs. 5 to 11 , pairs of longitudinal grooves 45, 46, 47, 48 bordering opposite edges of the first side 41 , the second side 42, the third side 43, and the fourth side 44, in each case allow weaving machine devices to be fixed to the longitudinal profile 11 using a fixation element in the form of an arc-shaped or U-shaped bracket having inwardly pointed tips engaging the pair of longitudinal grooves 45, 46, 47, 48, and/or using a fixation element having two jaws engaging the longitudinal grooves 45, 46, 47, 48.
