Definitions
- the invention relates to a jacquard machine according to the preamble of claim 1.
- a jacquard machine of the type mentioned at the outset is known, for example, from US Pat. No. 5,743,308.
- the actuator which is designed as an electromagnet, is arranged with a switching element between the spring arms of a two-armed circuit board, which is very disadvantageous for the small construction required.
- the components lying between the spring arms are difficult to access for maintenance and adjustment work.
- the spring arms are provided with locking lugs pointing outwards, which interact with fixed locking knives.
- the locking lugs are pre-tensioned against the locking knives by the spring force of the spring arms and must be released from the locking knives by bending in the spring arms by means of the actuator.
- the locking lugs are arranged on tongue springs connected to the circuit board and must be brought into engagement with the locking knives by spreading outwards by means of the actuator.
- the resilient arrangement of the locking lugs causes vibrations which impair the function of the jacquard machine. Since position of the invention
- the object of the invention is to improve a jacquard machine of the type mentioned.
- the switching element is arranged at the end of a spring tongue aligned in the direction of displacement and fastened to the displacement element outside the spring arms, the actuator being arranged laterally outside the spring arms and acting transversely thereto, the space between the spring arms is free of components, resulting in a very Space-saving, slim design of the boards results. Since both the switching element and the actuator are outside the circuit board, they are easily accessible for adjustment and maintenance work.
- a particularly advantageous jacquard machine is obtained according to claim 2, if at least one rigid catch for the locking of the board in the high position with which the actuator interacts is arranged on the sliding member.
- This training simplifies the construction, since there is only one catch, which is also accessible from the outside.
- the rigid detent also prevents unwanted vibrations and resonances, which not only extends the life of the jacquard machine but also enables higher performance.
- an embodiment according to claim 3 is advantageous, since each locking point for locking the sliding member with the actuator corresponds to a certain height of the shed.
- the actuator can be designed as an electromagnet.
- the configuration according to claim 5 as a piezo element is more advantageous.
- a further development of the jacquard machine according to claim 7 is particularly expedient, since adjustable stops which determine the down position allow further adjustment of the shed.
- the sliding link requires a guide in the machine frame, for which there are various design options.
- Claim 8 describes a particularly simple and space-saving solution.
- the lifting knives are designed in such a way that they perform a certain movement in the up and / or down position, as a result of which the elements to be switched are free from shape interference and / or from tensile forces and the switching is made possible or at least facilitated.
- FIG. 1 shows a circuit board in the low position and in the basic position of the spring arms in a diagrammatic representation
- Figure 2 shows the circuit board of Figure 1 in the coupling position of the spring arms
- Figure 3 shows the circuit board of Figure 1 in the middle position, in a modified diagram
- Figure 4 shows the circuit board of Figure 1 in
- FIG. 5 shows a modified circuit board in the central compartment position with an actuator designed as a piezo element, in a modified diagrammatic representation
- Figure 7 shows the switching element of Figure 6 in detail and in section VII-VII of Figure 6.
- a circuit board 2 of a jacquard machine in various working positions is shown in a schematic representation in FIGS. 1 to 4, parts which are not essential to the essence of the invention being omitted.
- the circuit board 2 has a sliding member 4, to which a strand 8 is connected at the lower end via an eyelet 6 and is biased against a machine frame 12 via a spring 10. By means of this prestress, the sliding member 4 is in the deep position T against a lower stop 14 preloaded on the machine frame.
- An eye 16 arranged in the strand 8 serves to carry a warp thread 18 in order to move it back and forth from the low position T in FIG. 1 via the middle position M in FIG. 3 to the high position H in FIG.
- the sliding member 4 is held in the longitudinal direction via a profiled back part 26 with a guide of the machine frame, which are not shown in detail here.
- the sliding member 4 contains two upwardly pointing spring arms 28a and 28b, which contain mechanical coupling means 30 in the form of outwardly pointing hooks 32, each of which can be coupled to up and down lifting knives 34a and 34b, which have corresponding drivers 36 for the hooks 32 ,
- the spring arms 28a and 28b assume a basic position shown in Figure 1, in which they are free of the lifting knives 34a, 34b, i.e. cannot be coupled.
- the displacement member 4 contains a resilient switching member 38 which can be actuated by means of a stationary actuator 40 in order to move the spring arms 28a and 28b from the basic position in FIG. 1 to the coupling position in FIG. 2 for the lifting knives 34a and 34b.
- the switching element contains an expansion wedge 42 which is arranged at the front end of a spring tongue 44 of the displacement element 4.
- the actuator 40 is, for example, part of an electromagnet 46, which is connected via a line 48 to an electronic control device which transmits a control signal to the actuator according to the standard.
- the sliding member 4 further includes a detent 52 in which the actuator 40 engages when the circuit board 2 with the sliding member 4 is in the high position H, as can be seen from FIG.
- the circuit board works as follows.
- FIG. 1 shows the board 2 in the deep position T, in which it is in contact with the lower stop 14.
- the spring arms 28a, 28b are also in the basic position, since the switching element 38 is also in the basic position. In this basic position it is a cooperation of the spring arms 28a, 28b with the lifting knives 34a, 34b is not possible. If the switching element 38 is activated by the control device 50 via the actuator 40 by means of a control signal, the expansion wedge 42 of the switching element 38 is driven between the spring arms 28a, 28b, as a result of which their coupling means 30 bring them into the displacement path of the lifting knives 34a, 34b. The board is then taken into the high position by one of the lifting knives 34a or 34b, which is currently in the low position.
- FIG. 4 shows an important state of the lifting knife in its highest position, the board being just above the high position. If the board is to remain selectively in the upright position, the actuator 40 is reactivated and latched with the catch 52, as a result of which the board can no longer follow it when the lifting knife goes back.
- the entire mechanism has a small over-movement at the high compartment position, which on the one hand makes it easier to couple and uncouple the spring arms on the lifting knives and on the other hand the actuation of the actuator 40, since the elements to be switched are relieved of the tensile forces on the strand.
- one of the lifting knives can catch the hook 32 of a spring arm, since the spring arms are deflected into the displacement path of the lifting knives 34a, 34b due to an upper fixed expansion member with running surfaces 53.
- the lifting knife then lifts the sliding member 4 and thus the circuit board 2 in accordance with the small over-movement and thus facilitates the disengagement of the actuator 40, whereupon the board can follow the downward movement of the lifting knife.
- the lifting knives 34a and 34b also perform a small downward movement in the low position, which makes it easier to disengage the spring arms from the lifting knives, so that the spring arms can spring back into the basic position.
- FIG. 5 shows the circuit board 2 of FIGS. 1 to 4, which is guided with its back part 26 in a guide 54 which is fastened to the machine frame 12.
- the actuator 40a in the example in FIG. 5 is not designed as part of an electromagnet but rather as part of a piezoelectric element 56, which is likewise fixed in place on the machine frame 12.
- FIGS. 6 and 7 show a modified circuit board 2a of FIG. 5, the guide 54 being arranged on a plate 58 of the machine frame 12.
- the arrangement is such that the guide 54 of a board also serves as a holder for the piezoelectric element 56 of the adjacent board.
- the circuit board 2a or the displacement member 4a of the circuit board of FIG. 6 has a plurality of notches 60, 60a, 60b distributed over the height, against which the actuator 40a can latch.
- the detents 60, 60a, 60b which are arranged at different heights, permit a correspondingly differentiated opening of the shed via a correspondingly different one Compartment height, since the compartment height is equal to the distance which corresponds to lifting the board from the low position of FIG. 1 to the high position of FIG.
- compartment height naturally also requires that the lifting knives carry out an appropriately adapted stroke. Under certain circumstances, the compartment height can also be increased downwards by the lower stop being adjustable downwards. Here, too, the stroke of the lifting knives must be adapted to a changed position of the lower stop.
