Definitions

  • the invention relates to a needle bed for a knitting machine.
  • Knitting machines have needle beds, for example in the form of knitting cylinders, dials or in the form of flat needle beds. It may be necessary to cool needle beds. This suggests the DE 40 24 101 C2 to incorporate into the inner circumferential surface of a needle cylinder a groove which is sealed by an annular lid. Connections on the lid allow the supply and discharge of cooling water.
  • Cylinders of knitting machines can reach a relatively large diameter. A correspondingly large diameter then has the ring-shaped lid. This must be permanently sealed regardless of occurring temperature fluctuations or other influences with the knitting cylinder.
  • GB 1 293 235 A1 From the GB 1 293 235 A1 is an arrangement consisting of a knitting cylinder and an associated circuit board ring known, wherein in the sinker ring channels are incorporated.
  • the channels serve to remove lint by means of an air flow. They also affect the heat distribution in the sinker ring.
  • this publication discloses a knitting cylinder having a rectangular cross-section extending in the circumferential direction cavity, which is connected to the inner circumference of the knitting cylinder with incoming and outgoing lines.
  • the needle bed For cooling the needle bed one or more cooling channels are provided in at least one of its segments. At least one cooling channel adjoins the contact surface of one of the segments. This opens up the possibility of easy production.
  • the cooling channel may be formed by a groove which is open to the contact surface. The closure of this groove and thus the completion of the cooling channel is effected by the adjacent segment, which bridges the groove with a flat or profiled contact surface and thus closes.
  • the needle bed is a knitting cylinder
  • its segments are preferably single-part or multi-part rings, which are arranged axially adjacent to one another with their contact surfaces.
  • the needle bed is a dial
  • its segments are preferably single-part or multi-part rings, which are arranged radially adjacent to one another with their contact surfaces.
  • the cooling channels connect to the contact surface.
  • one segment closes off the cooling channel of the adjacent other segment. Separate lids, closure means and the like are not required.
  • the cooling channels thus require no additional space.
  • effective cooling of the individual segments and thus the entire needle bed is achieved because the coolant can circulate directly in the cooling channel of the segment and thus in the needle bed.
  • the heat transfer inhibiting interfaces as in the prior art, for example, between pipe and segment body, are not present.
  • the annular segments are also dimensionally stable, relatively massive parts, which are already finished. Thus, the sealing of the cooling channels on the contact surfaces is not a technical difficulty.
  • the cooling channel may in principle extend in a train around the entire circumference of a segment.
  • the cooling channel is divided into individual sections which each only extend over a certain angular range of e.g. 20 °, 45 °, 60 ° extend on a contact surface and then change to the opposite side of the annular segment. In this way, high mechanical stability is associated with high cooling efficiency.
  • connection For the supply and removal of coolant, in particular cooling oil or cooling water, in the cooling channel and out of this, preferably two or more connections are provided. These are preferably oriented parallel to the needle channels of the needle bed and extend from the segment in which the cooling channel is formed, through the adjacent segment through to an outer end-side connection. This is preferably provided in a knitting cylinder at the lower annular end face.
  • the terminals are preferably on the outer peripheral surface of the largest annular segment.
  • FIG. 1 a needle bed 1 in the form of a knitting cylinder 2 of a circular knitting machine is illustrated.
  • the knitting cylinder 2 has on its outer peripheral surface to each other and to the rotation axis 3 of the knitting cylinder 2 preferably parallel needle channels 4.
  • the axis of rotation 3 and the needle channels 4 are usually oriented vertically.
  • the knitting cylinder 2 consists of at least two, but preferably a plurality of annular segments 5, 6, 7, which are arranged coaxially to the rotation axis 3 and axially connect to each other.
  • the segments 5, 6, 7 are preferably formed continuously over the entire circumference and in so far as one piece. However, if required, they can also be composed of sections which extend only over part of the total circumference.
  • the segment 6 is arranged between the segments 5 and 7. It has two axially facing in opposite directions bearing surfaces 8, 9, which in FIG. 1 are illustrated as flat ring surfaces.
  • the contact surfaces 8, 9 may be arranged in a plane on which the rotation axis 3 is perpendicular. However, they can also lie on a cone concentric with the axis of rotation 3 or be profiled.
  • the segment 5 has a contact surface 10, which is complementary to the contact surface 8 and bears against this.
  • the segment 7 has a contact surface 11 which is complementary to the abutment surface 9 and abuts against this.
  • the needle channels 4 extend beyond the segments 5, 6, 7 on the outside. They may have continuous or broken needle channel edges.
  • the radial thickness of the individual segments 5, 6, 7 may be the same or, as shown, differently sized.
  • the segment 6 lying between the segments 5 and 7 has the greatest radial thickness.
  • the segment 6 is preferably located approximately in that axial position in which the knitting tools seated in the needle channels 4 engage the knitting lock during operation.
  • the knitting lock is arranged annularly around the needle cylinder 2.
  • the knitting tools held in the needle channels have, in particular in the region of the segment 6, corresponding means in the form of feet which interact with the knitting cam.
  • One or more of the segments 5, 6, 7 are provided with cooling channels 12.
  • the segment 6 is provided with a cooling channel 12 which is connected via connections 13, 14 (FIG. FIG. 3 ) can be supplied with cooling medium.
  • the cooling channel 12 connects to at least one of the flat surfaces 8, 9. How out FIG. 2 can be seen, he connects in the present embodiment, both to the contact surface 8 and to the contact surface 9 at. It is in the form of grooves 15, 16, 17, 18, 19, 20, which originate alternately from the contact surface 8 and from the contact surface 9. The edge of each groove is completely surrounded by the respective contact surface 8 and 9 respectively.
  • the grooves 15 to 20 extend in a circular arc around the axis of rotation 3. Their number can be determined as required. It can be bigger or smaller, like the Figures 2 and 3 demonstrate.
  • the grooves of the two different sides are interconnected by bores 21, 22 (FIG. FIG. 3 ) and thus form a chain which extends from the terminal 13 to the terminal 14 and thus spans substantially the entire circumference of the segment 6.
  • the contact surfaces 8, 9, 10, 11 are preferably sealing surfaces which are mutually adhesive, another Sealant or simply by tight fit or by sealing elements (eg O-rings) can be sealed.
  • the contact surface 10 the grooves 15, 16, 17 introduced into the upper side of the segment 6 (FIG. FIG. 2 ).
  • the cooling channels are thus limited between two adjacent segments 5, 6 and 6, 7. They are formed in the present embodiment as a groove-like pockets in the segment 6 and are only closed by the adjacent segments 5, 7. But it is also possible to provide grooves in the segments 5, 7, which adjoin the corresponding contact surfaces 10, 11.
  • connections 13, 14 are preferably formed by bores which extend out of the segment 6 parallel to the axis of rotation 3 and are aligned with bores provided in the adjacent segment 7. At the bottom of the segment 7 connections can be provided, which allow a rotation of the knitting cylinder 2.
  • the knitting cylinder 2 described so far works in a circular knitting machine like an ordinary knitting cylinder.
  • its segment 6 is cooled by a cooling fluid, such as cooling water or cooling oil.
  • a cooling fluid such as cooling water or cooling oil.
  • the cooling medium touches not only the segment 6 but also the segments 5, 7 via their contact surfaces 10, 11th
  • the heat occurring in the region of the needle lock is dissipated by the cooling medium which flows through the segment 6.
  • grooves 15 to 20 in different segments 6, 7, 5 are mounted. These grooves 15 to 20 are then respectively connected to bores 21, 22, in which case e.g. the bore 21 extends from the segment 6 via its contact surface 8 into the segment 5 via its contact surface 10. The same may apply to the bore 22, which also connects grooves 15 to 20 and e.g. from the segment 6 over the contact surface 9 to the segment 7 extends over the contact surface 11.
  • FIG. 4 illustrates the needle bed 1 in the form of a dial 23, which consists of annular segments 24, 25. Like the segments 5, 6, 7, the segments 24, 25 are non-rotatably connected to each other and arranged concentrically to the axis of rotation 3 here.
  • the segments 24, 25 have contact surfaces 26 and 27, which are respectively formed on the inner and outer peripheral sides of the segments 24, 25 and in pairs abut each other. Needle channels 28 are arranged on the upper side of the dial plate 23 thus formed and extend radially to the axis of rotation 3.
  • one or more cooling channels 29, 29 ' are again provided, which extend through at least one of the segments 24, 25.
  • the cooling channel 29 can in turn be divided into individual grooves 29, 29 'in the form of pockets, which alternately adjoin the contact surface 26 and the contact surface 27 of the segments 24 and 25.
  • the connection between the individual cooling channel sections can take place through connection openings 39 between the cooling channel sections of the segment 24 and the cooling channel sections of the segment 25.
  • the number of connection openings 39 depends on the number of channel sections. With a connection opening 39, two channel sections, which are arranged in the segments 24, 25, connected. Not further illustrated connections allow the supply and discharge of cooling medium. This principle is also after the knitting cylinder FIG. 1 transferable, if desired.
  • FIG. 6 illustrates the segment 25 of the dial 23.
  • the segment 25 has a circumferential cooling channel 29 on.
  • the segment 24 is arranged (not shown).
  • the segment 24 has no cooling channel 29. It adjoins the abutment surface 27 of the segment 25 with the abutment surface 26 and thus forms the bottom of the cooling channel 29, which is arranged exclusively in the segment 25.
  • the cooling channel between the connection 13 and the connection 14 has a separating means 40 in the form of a web. This ensures that cooling medium, which is introduced through the connection 14 into the segment 25, initially flows around the segment 25 around the circumference, and is then discharged through the connection 13. This creates the best possible cooling.
  • the segment 24 has a circumferential cooling channel 29 ', which is arranged opposite the cooling channel 29 of the segment 25 (not shown). Also, the cooling channel 29 'then has a release agent 40. Such circumferential cooling channels are also possible in the knitting cylinder.
  • FIG. 5 illustrates the interaction of the knitting cylinder 2 and the dial 23, with the corresponding Knitting tools 30, 31 are stocked.
  • the knitting tools 31 can have feet 34 to 37 at different locations, wherein for cooling the knitting cylinder 2 a cooling in a region of the middle segment 6 is sufficient.
  • the segments can be sealed against each other with seals, for which corresponding annular grooves 38, 41 may be provided.
  • a needle bed 1 of a knitting machine is segmented.
  • the segments 5, 6 adjoin one another with abutment surfaces 10, 8. From at least one of the interfaces 10, 8 exit cooling channels, which are formed for example in the segment 6.
  • the adjacent segment 5 covers these cooling channels and thus closes them.
