Definitions

  • the invention relates to a flat knitting machine with needles longitudinally displaceable in its needle beds and between the needles pivotally mounted boards, which are controlled by a machine slide arranged on the board lock, wherein the board lock has a control track arranged on the boards control feet, which is bounded by at least two lock parts of which at least one is switchable.
  • Such a flat knitting machine is for example from the EP 0 652 315 B1 known.
  • the blanks of this flat knitting machine can be pivoted into or out of the comb gap with the aid of the board lock.
  • a pivotally mounted lock part is provided that is spring-loaded in its direction of movement.
  • This pivoting lock part cooperates with a switchable lock part.
  • the control track for the control feet of the boards is formed, with the width of the control track, the width of the control feet and possibly existing, trapped between the boards and the lock parts foreign bodies can adjust independently.
  • the pivotable lock part is, after the foot of the last board of the needle chamber has left the control path, spring loaded at its opposite, switchable lock part and thereby closes the control path for the control feet. Therefore, in each row of knitting, in front of which the machine slide was located outside the needle space, the control track of the outermost board must be in the control path against the spring force on the swiveling lock part acts to be opened. This leads to a special stress on the control feet of the outermost boards and consequently to increased wear.
  • a flat knitting machine is known in which the boards are moved by means of a board lock, which allows an adjustment of the lowest position of the boards to the comb gap.
  • the control track for the board feet is not changeable in their width. Should it come to the penetration of foreign bodies, such as yarn residue or dirt in the control track for the control feet of the boards, this can lead to jamming of the control feet of the boards in the control track, causing damage to the control feet and / or the control track by itself can pull.
  • the present invention is based on the object to provide a flat knitting machine, which allows a safe and low-wear moving the control feet of the boards arranged between the needles.
  • the object is achieved with a flat knitting machine of the type mentioned, which is inventively characterized in that between the two lock parts, a spacer is provided and the two lock parts spring loaded over the spacer abut each other in a mutual minimum distance.
  • the spacer ensures that the control feet of the outermost boards of the needle chamber, the control track of the board lock must not first open, but can enter the control track without major loads.
  • the mutual minimum distance of the lock parts can at least approximately correspond to the height of the control feet of the boards. Then the control feet of the outermost boards of the needle chamber can enter the control track without additional friction.
  • the mutual distance of the cam parts against the spring loads beyond the minimum distance can be increased.
  • This design allows widening of the control track beyond the height of the control feet of the boards, as far as in the control track foreign bodies should have set, which hinder the boards in their movement. This means that the control feet of the boards, which are hampered in their movement out of the comb gap, are not damaged by the control track.
  • both lock parts can be mounted perpendicular to the direction of movement of the machine slide movable on a lock plate of the board lock, preferably one of the two lock parts switchable and the other Schlossteit can be spring-loaded.
  • the at least one switchable lock part moves along the at least one spring-loaded lock part via the spacer during the switching operation.
  • this automatically follows the switchable lock part in one of the directions of movement.
  • this lock part is carried over the spacer, which can be arranged both on the switched and the non-switched lock part, with the movement of the switched lock part.
  • the spring-loaded lock part can also perform a pivoting movement in a corresponding configuration instead of a movement parallel to the lock plate when it follows the movement of the switchable lock part via a spacer or is moved by control feet of disabled in their movement boards.
  • stops can be formed for example by a bolt in the lock plate, on which a stop surface of the spring-loaded lock part comes to rest.
  • the at least one switchable lock part can be moved via a switching strip displaceably mounted parallel to the movement direction of the machine carriage. This is a structurally simple and robust solution for switching the lock parts.
  • the switching strip may have at least one control cam, in which engages a arranged on the at least one switchable lock part guide body. By moving the safety edge so that also changes the position of the switchable lock part and thus the control track for the boards.
  • the switching strip can be arranged on the side facing away from the lock parts of the lock plate, where sufficient installation space is available and it can be driven in a simple manner.
  • switchable lock parts are provided, each cooperating with a spring-loaded lock part, one of the switchable lock parts with respect to the vertical center axis of a arranged below the board lock on the machine carriage knitting cam in the direction of movement of the machine carriage leading the other switchable lock part lagging is arranged.
  • the switchable lock parts such that with the help of the cam lock leading the switchable lock part, the boards pivot into the comb gap and with the help of the trailing, spring-loaded lock part are pivotally out of the comb gap or that the blanks are held in their pivoted out of the comb gap position by both spring-loaded lock parts.
  • Fig. 1 shows a board lock 1, which is arranged above a knitting lock 200 on a lock plate 100.
  • the board lock 1 has a total of four lock parts 2, 3, 4 and 5.
  • the lock parts 2 and 3 are leading to the center axis M of the knitting lock 200 and the lock parts 4 and 5 arranged lagging.
  • the castle parts 2 and 3 form a control path 60 for control feet 6 'from out of the FIGS. 5 and 6
  • the cam followers 200 trailing the cam lock 4 and 5 form a control track 61 for the control feet 6 'of the boards, which is offset from the control track 60 down, causing the boards are pivoted back out of the comb gap 300 out.
  • the width of the control tracks 60, 61 corresponds to the height of the control feet 6 'with a certain tolerance allowance.
  • the lock parts 3 and 5 are switchable. They are longitudinally movably mounted with guide bodies 31, 51 in oblong holes 101, 102 of the lock plate 100 perpendicular to the direction of movement L of the machine carriage and can thus perform movements in the direction of the arrows V1, V2 and V1 ', V2'.
  • the lock part 3 has a bolt 32 which engages in a switching cam 71 of a switching strip 7.
  • the lock part 5 a bolt 52 which engages in a further switching curve 72 of the switching strip 7.
  • the switching strip 7 is mounted on the lock parts 2, 3, 4 and 5 opposite side of the lock plate 100 parallel to the longitudinal side 111 of the lock plate 100 slidably, which in particular from the FIGS. 5 and 6 is apparent.
  • the switching curves 71, 72 are mirror images of each other, whereby the lock parts 3, 5 perform opposing movements when the switching strip 7 is moved.
  • Fig. 1 is the safety edge 7 in Direction of the arrow HL has been moved to its left end position. As a result, the lock part 3 was brought into its raised position and the lock part 5 in its lowered position.
  • the interacting with the switchable lock parts 3, 5 lock parts 2, 4 are mounted longitudinally movable with guide bodies 21, 41 in slots 103, 104 of the lock plate 100 and can thereby perform movements in the same directions as the lock parts 3, 5.
  • the lock part 2 is acted upon by a force acting in the direction of the arrow F of a spring 8, which is supported on a holder 9, and the lock part 4 by the force of a spring 8 ', which is supported on a holder 9'.
  • Both lock parts 2, 4 have a spacer 22 or 42 and are due to the action of the springs 8, 8 'at their associated switchable lock parts 3, 5 at.
  • the lock parts 2, 4 follow the switching movements of the lock parts 3, 5 in a desired minimum distance.
  • the spacers 22, 42 are arranged on the spring-loaded lock parts 2, 4; However, they could also be arranged on the lock parts 3, 5.
  • the distance between the lock parts 2, 3 or 4, 5 formed by the spacers 22, 42 corresponds to the height of the control feet 6 'of the boards 6 with a tolerance allowance.
  • the force of the spring action of the lock parts 2, 4 is selected so that the control foot 6 'of a board 6, which is hampered in the movement out of the comb gap 300 out in the control path 60, 61 foreign object, the lock part 2 or 4 in move to the arrows F, F 'opposite direction and thus the control track 60, 61 can widen.
  • the control tracks 60, 61 which are formed by the lock parts 7, 5 brought into position by the switching strip 7 and the spring-loaded lock parts 2, 4 cooperating therewith, are formed here by way of example in that the spring-loaded lock parts 2 and 4 are in the same plane move like the switchable lock parts 3, 5.
  • the spring-loaded lock parts 2, 4 but could also by a pivoting movement of the active surface of the switchable lock parts 3, 5 away or move to this and thereby form the control tracks 60, 61.
  • Fig. 2 shows the board lock 1 with all components, as well as in Fig. 1 are described, in the direction of movement of the machine carriage in the direction of arrow R to the right.
  • the switching strip 7 is moved in the direction of the arrow RL in its right end position.
  • Fig. 3 the board lock 1 is shown with a middle position of the switching strip 7.
  • the machine carriage can move in both directions, which is expressed by the double arrow D. If the switching strip 7 is brought into the illustrated middle position, then both switchable lock parts 3, 5 are lowered. The spring-loaded lock parts 2 and 4 follow this movement.
  • the boards 6, which pass through the control tracks 60, 61 with their control feet 6 ', are thereby in their position pivoted out of the comb gap 300.
  • Fig. 4 Finally, shows the board lock 1 with a position of the lock parts 2, 3, 4 and 5 and the safety edge 7, as well as in Fig. 1 is shown.
  • the difference to Fig. 1 is that now the machine slide is located at the edge of the needle room and begins to run in the direction of arrow L. It comes thus first the leading lock parts 2, 3 and then the cam lock 200 lagging lock parts 4, 5 in contact with the sinker feet 6 '.
  • the lock part 2 rests on the spacer 22 on the lock part 3 and the lock part 4 via the spacer 42 on the lock part 5, whereby the control tracks 60, 61 for the control feet 6 'with a width which is slightly larger than the height of the control feet 6' to be formed.
  • the first control foot 6 experiences the same friction forces when passing through the control tracks 60, 61 as the subsequent control feet 6'.
  • the sectional view in Fig. 5 shows a board 6 in its moved into the comb gap 300 in deep position T.
  • the lock part 3 has been brought into its raised position.
