Description

The present device relates to a device according to the preamble of claim 1 and a weaving machine with such a device.

In the U.S. 3,888,284 describes an arrangement for coupling and uncoupling the heald frames with a shaft operation, a coupling part being provided on the side of the heald frame and the shaft drive.

In this arrangement, the heald frame is coupled to the sheep drive by moving the heald frame. For this purpose, the coupling part is positioned on the side of the shaft drive in guide parts, which is arranged in a stationary manner in the area in which the coupling process takes place. In this arrangement, the shaft rods are held by the knee lever of the shaft drive.

On the other hand, the shaft rods not used in the technical training are known to be pivoted to the side, the shaft rods either lying loosely on the frame or being held exclusively by the toggle lever of the shaft drive.

This results in the disadvantages that the shaft rods rest below the heald frames or are moved up and down by the toggle levers, but there is no relative movement between the shaft rod and the toggle lever. On the one hand, this means that standing damage in the joint between the shaft rod and toggle lever is unavoidable.

The present invention has for its object to a device for receiving shaft rods create that keeps the shaft rods movable in a defined position.

This object is achieved according to the invention with the characterizing features of claim 1.

A loom with a device according to claim 1 is characterized according to the invention by the features of claim 8.

With this arrangement, the occurrence of standing damage can be avoided.

Advantageous embodiments of the invention result from the dependent patent claims.

The invention is explained below with reference to the accompanying drawings.

a plan view of a portion of the device shown in Figure 2.

With the device in question, the shaft rods that are not required for the formation of a compartment are held in a defined position.

FIG. 1 shows a shaft rod which has been shut down and a shaft rod which is ready for operation, and FIG. 2 shows only a shaft rod which has been shut down. The shaft rod 1 contains a coupling part 2 of a shaft coupling, a rod 3, on which the coupling part 2 and on the other hand a joint 4 are fastened. A screw connection is advantageously selected for fastening the coupling part 2 and the joint 4. The shaft rod 1 is rotatably connected via the joint 4 to a toggle lever 5 which is part of a shaft drive, not shown.

In the embodiment shown in Figure 1, the device includes an elongated body 8, which is provided on one longitudinal side with a number of slots 9, which are arranged in a row at constant intervals, and an end strip 10, which is detachable on the body 8 is attached and closes the slots 9 to hold the shaft rods 1.

In the embodiment shown in FIGS. 2 and 3, the device consists of an elongated body 11 which has a section 12 with a number of recesses 13 on one longitudinal side. In the illustrated embodiment, section 12 is formed in one piece with body 11. It is pointed out that section 12 can be formed as a separate part and can be attached to body 11 by suitable means.

The recess 13 is delimited by two freely projecting webs 14, 15 which are elastic. In order to enable the deflection of the webs 14, 15, a slot 16 is provided in each case between the wall parts 15, 14 delimiting the adjacent recesses 13. The webs 14, 15 have at their free end a bead 17 which is directed towards the recess 13 and extends over the width of the web 14, 15. Through the beads 17 there is an opening width formed, which is smaller than the rod cross section, so that the rod 3 (shown in dashed lines) is not inadvertently removable from the recess 13.

While the embodiment according to FIG. 1 is intended for manual storage of the shaft rods, the embodiment according to FIGS. 2 and 3 is suitable for automatic feeding and removal of the shaft rods when changing the shaft.

Claims (7)

1. A loom having shaft rods which can be coupled with the shaft and are connected to the shaft drive and having a member (8, 11) to which the shaft rods are supplied and from which they are removed respectively during the shaft changing operation,
   characterised in that to receive the shaft rods not required during shedding the member (8, 11) has a plurality of recesses (9, 13) open on one side, into which the shaft rods (1) can be inserted,
   and in that the member is disposed beneath the shafts and outside the range of movement of the active shaft rods (1) and coupling parts (2, 4) respectively so that the shaft rods (1) not required can be moved by the shaft drive (5).
2. A device according to Claim 1,
   characterised in that the recesses (9, 13) are aligned parallel to one another and are disposed lying in a row with constant spacing.
3. A device according to one of Claims 1 or 2,
   characterised in that the recesses (9, 13) have a slot-shaped construction.
4. A device according to one of Claims 1 to 3,
   characterised in that the recess (13) is limited on both sides by a resilient arm (14, 15).
5. A device according to Claim 4,
   characterised in that at its free end each arm (14, 15) has a swelling (17), which is directed towards the recess (13).
6. A device according to one of Claims 1 to 4,
   characterised in that the member (8, 13) is made of plastic.
7. A device according to Claim 1,
   characterised by a closing member (10) for closing the recesses (8) open on one side.
