Description

The invention relates to a coil frame according to the preamble of claim 1 and a holder according to the Preamble of the independent claim 12 and a partition plate according to the preamble of the independent claim 13.

In the case of weaving machines equipped with thread delivery devices Bobbin racks used to view the supply bobbins for an optimal thread course and easy handling to hold when changing bobbins or during maintenance work. The The bobbin rack is placed on the floor behind the thread delivery devices posed. If necessary, the coil frame is even with structurally combined a carrying device for the thread delivery devices. Since usually several coils (e.g. for different Colors and reserve spools for the same color) are to be held, and for a spool change or for others Work requires quick and convenient access to the coils and since the individual coils or pairs of coils must still be separated from each other so that the threads do not interfere with each other and fluff and other thread abrasion and contaminants do not contaminate the coils, separating plates are inserted into the coil frame, which are either horizontal floors or vertical compartments define in the otherwise open coil frame.

From a brochure by ROJ ELECTROTEX, IT, "Racks and Spool holder: General catalog ", are spool frames in different designs and accessories can be removed, which can be combined with one another in a modular manner, in order to Coil frames of different shapes and different applications to be able to create. For attaching the partition plates on the frame struts (around the bobbin frame in horizontal To divide floors and / or adjacent compartments), at least two for each partition Clamping flanges used with one end on each Frame strut can be fixed, and with the other end under Using a counter flange screwed to the partition plate (cover sheet, D3, sheet B7, sheet I13). The edge area the cover plate has points of attack for the counter flange and the clamping flange and through holes for the tensioning screws pulling the cover flange against the clamping flange on. These known coil frames consist of many components and must either be used by Be assembled from scratch or largely at the manufacturer to get finished. In the first case is special skill and required a lot of time. In the second case, high ones arise Transportation costs. In particular, the attachment of the partition plates is troublesome, especially if several floors or side by side Compartments are to be formed in the coil frame.

The invention has for its object a bobbin of the type mentioned and a holder for partition plates and finally partition plates for such a bobbin to indicate a transport-friendly partial pre-assembly allow to simplify assembly and a wide range different bobbin configurations.

The object is achieved according to the invention with the features of claim 1 solved.

The holder enables a new type of attachment of the partition plate, which are only inserted into the pocket and then in their final position using the positioning and Locking part is secured. The partition plate can be also bring in if there are already other separating plates in the coil frame should be installed. It is not compulsive Assembly process required because the holder inserting the Partition plate also possible with pre-assembled coil frame. Finally, attaching the partition plate is easy and without the help of a special tool. The assembly process can be carried out quickly.

In the embodiment according to claim 2 there is a fixed Seat of the partition plate in the two pockets with large power transmission and cheap lever arms. The Manufacturing is easy because the holder turns out to be one piece Form part can either be made of plastic or Diecast. A compact form of the holder is in the embodiment given according to claim 3. Furthermore, the partition plate supported extensively.

The embodiment according to claim is particularly advantageous 4. The locking element can be inserted and locked by hand. No special tools are necessary. With a regrouping or retrofitting the bobbin rack will only be easy Tools used to get the locking elements out of their To solve the intervention. Thanks to the positive and non-positive connection the locking element even under operational vibrations do not solve automatically.

The embodiment according to claim 5 is also expedient, because the deepening allows the flexibility of the Use the partition plate at least in some areas to ensure a firm one Locking seat of the locking element and thus a fixed To reach the holder of the partition plate, at which the insert pocket just a positioning without any noteworthy bracket effect has to perform.

A particularly important point of view is included in claim 6. The division of each partition plate into two overlapping Partition plate parts offer several advantages. Because everyone Partition plate, so to speak, only on an edge area on the holders is set, it can also be used or removed, if there are additional separating plates in the bobbin frame are mounted. Furthermore, the partition plate parts can be relative to each other to move the bobbin to each adjust appropriate size. Furthermore, the two partitions from each other. After all, that is Transport volume for the partition plate parts smaller than that Transport volume of one-piece and large partition plates.

In the embodiment according to claim 7 are independent the same holders are used for the type of attachment of the partition plates, what manufacturing technology and in terms of storage is cheap. It also reduces the cost of identical holders, since they are produced in large numbers become.

In the embodiment according to claim 6, there is a stable Structure of the coil frame. Furthermore, the coil frame changeable in depth. The overlap of the plate parts ensures that regardless of the chosen depth of the bobbin the dividing plates overlap each other. At a Adjusting the depth of the bobbin frame requires the dividing plates not to be detached from the holders.

An expedient embodiment of a coil frame with trapezoidal plan is evident from claim 9. Through the Alignment of the spoon-shaped projections becomes the partition plates stably supported.

In the embodiment according to claim 10, the holder a firm fit on the frame struts. They can also be subsequently adjust along the frame struts and again fix.

The embodiment according to claim is particularly expedient 11 because the prefabricated transport units have little transport space claim and the user of the bobbin enable simple and quick installation. The manufacturer the transport units can already be used for many applications Provide suitable arrangements for the holder and the mandrel support.

The holder according to claim 12 is an inexpensive to manufacture Shaped part, which is in the construction of coil frames in can be used universally and a new method of attachment for partition plates. Because the dividing plates only inserted more into the pocket and then using the Positioning and locking part need to be secured, the dividing plates can also be partially Insert or move the assembled bobbin frame.

The partition plate according to claim 13 stands out thanks to it Two-part design due to a considerably simplified assembly, because the separating plate parts also in the coil frame can be used if other partition plates already are mounted. Furthermore, the overlapping allow Partition plate parts also the subsequent changing of the depth of the bobbin frame, as it is only on the edge area on the holders are fixed and project with their free ends.

An essential feature of the invention is that Use of this new holder and the specially trained Separation plates from the manufacturers of the bobbin rack in the location is relocated, inexpensive transportable transport units prefabricated to the user the structure of the Simplify bobbin, and because of the holder and the formation of the partition plates the assembly of the partition plates is simple and convenient.

A bobbin frame C, as is typical on weaving machines is used for holding thread spools, for example from four vertical frame struts 1, 2, 3, 4, which are arranged in the corner points of a trapezoid, so that the two frame struts 1, 2 are widely spaced while the frame struts 3, 4 are close together. The frame struts 1 to 4 are below each other by a foot part 6 connected, a horizontal frame strut 5, one has beam-like base 6 'and wheels 7. Are upstairs the frame struts 1 to 4 together by a head part 8 connected, in which also a horizontal frame strut 9, approximately parallel to the lower frame strut 5, is provided is. The frame strut 9, like the frame strut 5, is telescopic adjustable in length to the depth of the bobbin frame C to be able to adapt to the respective needs.

On the two frame struts 3 and 4 are along their length distributed several plate-like inserts 11 attached, each contain a drain eyelet 12 for the thread. By the inserts 12 defined working levels of the coil frame C are spatially separated from one another by partition plates P, the partition plates P are approximately horizontal and apart are approximately equally spaced. Any partition plate P consists of two plate parts P1 and P2, the Plate part P2 the plate part P1 under (or over) engages so that the plate parts P1, P2 overlap each other and support. Each plate part P1 or P2 is at least a holder H fixed, the height adjustable on the respective frame struts 1, 2, 3, 4 is fixed. Further are located on the frame struts 1, 2, 3, 4 coil mandrel carriers S with which the thread spools are attached. At 10 it is indicated that the partition plate part P1 is cut out somewhat is so that when you push the horizontal Frame struts 9, 5 a minimum depth of the coil frame is adjustable. When pulling apart the horizontal frame struts 9, 5, the depth can be increased considerably. For example, the coil frame has a height between 1.6 m and 2.1 m seen in the direction of the frame struts 9, 5 Depth between 350 mm and 680 mm. The distance between the partition plates P can be approximately 300 to 350 mm. The Separation plates are advantageously made of plastic or Sheet.

2 and 3, the holder H is clearer and in his Installation position in the coil frame C shown in FIG. 1.

The holder H has a sleeve-shaped base body 13 an inner bore 14 into which a maggot clamping screw 15 protrudes with the holder H in any position on the frame strut 1 to 4 can be determined. With the base body 13 is integrally formed a platform 16 which is approximately vertical runs to the axis of the inner bore 14 and from a trapezoidal base part 17 and one approximately in the middle thereof extending, spoon-shaped extension 18. Of the Base part 17 comprises the base body 13 like a collar and points first surface areas 24 on both sides of the base body on, each with an integrally molded ears 22 an insert pocket Define T on one side of the base body 13. The insertion pocket 13 serves to define the edge area the partition plate P.

In a second surface area 23 on the extension 18 an oval or circular, shallow depression 19 is provided, in the middle of which there is a holding opening 29. A Corresponding recess 19 'may be on the underside of the Platform 16 may be shaped.

A positioning and is used to fix the partition plate P. Locking part 20, which in this embodiment as mushroom-shaped locking element with a flat or rounded Head 25 and a stem extending downward therefrom 21 is formed. The shaft 21 fits into the holding opening 29 platform 16 and has at least one longitudinal slot 26 provided that the shaft 21 at least near the end in two Divides halves. Outside there are locking elements 27 on the shaft 21, e.g. Flanges formed, which are extended with inclined ramps 28 are.

The partition plate P consists of two partition plate parts P1 and P2. The partition plate part P1 is for example with the holder H of Fig. 3 set such that initially the edge area of the plate part P1, the one with the outline of the body 13 matching cutout 30 is provided, with lateral insertion surfaces is inserted into the insertion pockets T. The Insert pockets T offer little compared to the plate part P1 Game, so that the plate part P1 when inserting can also tilt something. Then the plate part P1 is on the Platform 16 placed before the shaft 21 with the ramps 28 ahead through a through opening 30 of the plate part P1 is inserted and into the holding opening 29. By further pressure on the head 25 get the locking elements 27 to the underside of the platform 16. When pushing through through the holding opening 29, thanks to the ramps 28, the locking parts 27 in the area of the longitudinal slot 26 to one another pressed until finally after exiting the bottom Mouth of the holding opening 29 spread apart elastically and the, if necessary specially shaped, mouth reach behind the holding opening 29 in a positive and non-positive manner. The recess 19 allows the elasticity of the plate part P1 and use it a little in the recess 19 press in, so that a tension between the on the Platform 16 overlying plate part P1 and the locking elements 27 occurs.

However, this bracing is not absolutely necessary. It would also be conceivable the distance between the bottom of the Head 25 and the locking elements 27 generously dimensioned since the locking elements 27 anyway positive act and a release of the plate part P1 due to the Engagement of the cutout 30 on the base body 13 and the insertion surfaces in the pockets P is no longer to be feared. The free end of the plate part P1, designated 31, overlaps the free end, designated 32, of the second plate part P2, the same way with at least one other Holder H is set.

The positioning and locking part 20 could also be one in a threaded hole in the platform 16 can be screwed in and if necessary be a screw that can be secured with a lock nut, which expediently has a head which can be rotated by hand.

In Fig. 1, the two plate parts P1, P2 are different configured with regard to the trapezoidal shape of the Bobbin. With a square or other bobbin frame can the two partition plate parts in about have the same size and shape. It is important that their overlap is so large that over the entire adjustment range horizontal frame struts 9, 5 maintain the overlap remains. It is enough to insert the dividing plates vertically if necessary, hanging only one partition plate part P1 or P2 to be arranged and attached to at least two brackets.

The frame struts 1 to 4 are attached to them Spool mandrel carriers S and the holder H are preferably pre-assembled. The frame struts 3 and 4 are even through the inserts 11 connected to each other and to the frame struts 1 and 2 combined into a small transport unit. To belong the stacked partition plate parts P1 and P2 as well as the Head and foot 6 and 8, so that there is a total very small transport size for the already largely prefabricated and therefore results in an easy-to-assemble coil frame. The locking elements are expedient already stowed in the holding openings 29 because, thanks to the The locking effect cannot fall out automatically.
