Description

The invention relates to a flat knitting machine having a machine body having a machine room according to the preamble of claim 1.

In modern flat knitting machines, bobbins are attached to bobbin holders on bobbin trays and / or behind the machine body to bobbin holders above a machine body.

The yarn bobbin holders used in this case are usually firmly connected to the coil table or the holding devices provided for this purpose. Your position can not be changed without much effort.

The rigid arrangement of the yarn package holder has the disadvantage that the accessibility to the rear needle beds and yarn guides and the engine room is severely limited. It must first be removed at least all Garnspulenhalter, which are located behind the machine body, what z. As in the correction of disturbances in the current production process is very time consuming and therefore expensive, since the downtime of the machine in which is not produced, are increased.

Furthermore, it is known to mount additional Garnspulenhalter on mobile racks, which, however, severely restrict the space around the machine. These extra bobbin holders are also in the way when the machine needs to be repaired or serviced.

From the DE 36 34 578 A1 is a flat knitting machine with Garnspulenhaltern known. According to one embodiment, yarn bobbin holders for additional bobbins can be arranged in groups distributed over a plurality of individually detachable back wall panels of the flat knitting machine. In order to service the machine, the back panel panels must be removed along with the bobbin holders and set aside. For this purpose it may be necessary to remove the yarn packages from the yarn package holders. The maintenance of a machine is therefore very expensive.

Object of the present invention is to develop a flat knitting machine so that it can be serviced or repaired faster and easier.

This object is achieved according to the invention by a flat knitting machine having the features of claim 1.

Thus, the machine element does not have to be completely detached from the flat knitting machine and set aside. It may remain on the flat knitting machine, in particular on the machine body. Thus, for example, it is not necessary to remove bobbins from the machine element should they be located thereon. It is particularly advantageous if the machine element can be displaced in several directions relative to the machine body. Thus, it is possible to make almost all locations of a machine room accessible for maintenance or repair work.

The at least one machine element is arranged horizontally displaceable relative to the machine body. It can be provided that the machine element can be moved to the left and right as needed. In principle, however, it is also conceivable to arrange the machine element so that it is vertically displaceable. Furthermore, it is conceivable that the machine element is arranged pivotable with respect to the machine body. By corresponding displacement of the at least one machine element, different areas of the flat knitting machine, in particular of the machine room, can be made completely accessible.

The at least one machine element may be movable out of the geometry of the flat knitting machine. Thus, it does not hinder the repair and maintenance.

On the machine element, one or more coil holders may be arranged. As a result, additional coil holders, which are arranged separately from the flat knitting machine behind the latter, can be dispensed with. In particular, yarn bobbins can thereby be close to the machine be arranged. The bobbin holders can be moved together with the machine element for repair and maintenance work. This eliminates the need to remove the bobbins from the bobbin holders when maintenance is required. The downtime of the flat knitting machine can be reduced.

The bobbin holders can be arranged on brackets, which in turn can be arranged on the machine element. Thereby, the attachment of the coil holder can be simplified to the machine element.

The machine element comprises in a first alternative, a rear wall part. In particular, during normal operation of the flat knitting machine, the rear wall part can cover the machine room to the rear and thus prevent intervention in the operating room when the machine is running. On the rear wall part bracket for coil holder or coil holder can be arranged directly.

The machine element comprises in a second alternative a Spulentischteil. In particular, the spool table can be divided and parts of the spool table can be displaced separately relative to the flat knitting machine, thereby releasing a thread guide or needle bed for maintenance.

According to a particularly preferred embodiment, a plurality of machine elements may be provided. By corresponding displacement of the machine elements, different areas of the flat knitting machine can be made completely accessible. The machine elements can be shifted together in one direction or they may be displaced, for example, separately in opposite directions.

According to a further embodiment of the invention it can be provided that a guide element part of a guide element for thread control units is arranged on the machine element. For example, a thread control unit can be arranged on the guide element, which can have a thread brake and can control the thread tension. Although the guide elements or parts thereof are displaceable relative to the flat knitting machine, a thread loop formation can be prevented. Thus, a flat knitting machine after the repair and maintenance work quickly ready for use again.

It is particularly preferred if a machine element has both a rear wall part and a guide element part.

Further features and advantages of the invention will become apparent from the following description of exemplary embodiments of the invention, with reference to the figures of the drawing, which shows details essential to the invention, as well as from the claims. The features shown there are not necessarily to scale and presented in such a way that the features of the invention can be made clearly visible. The various features may be implemented individually for themselves or for a plurality of combinations in variants of the invention.

In the schematic drawing embodiments of the invention are illustrated and explained in more detail in the following description.

The Fig. 1 shows a rear view of a flat knitting machine 100 with two machine elements 10, 20, each having stirrups 12, 22, on which Garnspulenhalter 11, 21 are arranged. Furthermore, the machine elements 10, 20 comprise rear wall parts 13, 23.

Over the rear wall parts 13, 23 coil tables 30, 40 are arranged, which also have yarn bobbin holders 31, 41. The coil table 30 is part of the machine element 10 and the coil table 40 is part of the machine element 20.

Above the coil tables 30, 40 there is arranged a guide element 50 for receiving thread control units, not shown here, which comprises vertically aligned guide element sections 52, 53 and a horizontally oriented guide element section 51. The guide member 50 is connected to a machine body.

The machine elements 10, 20 cover in the operating position shown a machine room completely backwards.

As the presentation of the Fig. 2 can be seen, the machine elements 10, 20 with respect to the flat knitting machine 100 are horizontally displaceable. In the illustration shown, the machine elements 10, 20 are displaced together to the left. Thereby, a machine room 110 of the machine body 120 in the area 130 is accessible. The representation of the Fig. 2 It can also be seen that in order to access a part of the machine room 110, it was not necessary to take out yarn packages from the yarn package holders 11, 21, 31, 41, but that they were displaced together with the machine elements 10, 20. Maintenance work is considerably simplified and accelerated.

The representation of the Fig. 3 It can be seen that here the machine elements 10, 20 were displaced together to the right to release the machine room 10 in the area 140 for maintenance.

Of the Fig. 4 It can be seen that the machine elements 10 and 20 are also displaceable in different directions and independently. Here, the machine element 10 has been displaced to the left, and the machine element 20 has been shifted to the right, thereby the Machine room 110 in area 150 to make accessible for maintenance and repair work.

From the FIGS. 2 to 4 shows that the machine elements 10, 20 are arranged so displaceable on the flat knitting machine 100, that all areas 130, 140, 150 of the machine room 110 can be made accessible for maintenance and repair work.

In the embodiment of the Fig. 5 it is provided that the guide element 50 is divided into two parts and in particular is not arranged on the machine body 120, but the individual parts 50a, 50b of the guide member 50 are arranged on the machine elements 10, 20 and thus are displaced together with them. In this case, the guide element part 50a comprises the guide element sections 51a, 52a and 52b, while the guide element part 50b comprises the guide element sections 51b, 53a, 53b. Thus, it is possible to move together with the guide element parts 50a, 50b disposed thereon thread control units, in particular outside the contour of the flat knitting machine 100 to move.
