The warp knitting machine 1 provides at least one bed block 10 which is detachable from the frame 2 and which can be installed in the frame 2 in at least two positions A and B. In this way, spinning rollers of different sizes can be installed in the rigid frame 2 such that the path of the yarn is as short as possible from the starting point to the first turning device.

Description

Warp knitting machine with frame for spinning roller bearings {WARP KNITTING MACHINE WITH A FRAME FOR THE YARN ROLLER BEARING}

The present invention relates to a warp knitting machine having a rigid frame for supporting a bearing against a journal of a spinning roller.

In warp knitting machines known in the art, the frame is determined for the spin roller diameter being precisely set. When the diameter of the spinning roller is attached to the spinning roller having a diameter of 30 inches, that is, 762 mm, a larger size spinning roller, such as a spinning roller having a diameter of 40 inches, that is, 1,016 mm, cannot be used. In the case where the frame is provided for a 40 inch spinning roller, it is of course possible to install a smaller size spinning roller. In this case, however, a thread path of unnecessary length has to be taken up to the work tool and the direction changer connected in series. Therefore, there is a fear that the vibration generated by the mechanical movement and the configuration of the nose acts on the yarn to be conveyed and negatively affect the appearance of the finished product.

German Patent Publication No. 2,147,241 discloses a frame for warp knitting machines in which a rod portion and a coupling sleeve are assembled. In this patent, a frame of each required number and arrangement of spinning rollers can be adapted. However, disassembly and assembly of the frame required for this is very wasteful.

The present invention relates to a warp knitting machine of the above-described technique, and relates to a problem in which a warp knitting machine is suitable even if the diameter of the spinning roller is different, and nevertheless, the yarn being conveyed has each shortest free thread path.

According to the invention, the object of the invention is solved by at least one bed block detachable from the frame and attachable to the frame in at least two positions.

In this arrangement, the placement of the frame on spinning rollers of different diameters is performed by at least one bed block being separated from the frame and fed back to another position. This positioning is achieved with low installation costs.

Advantageously, the detachable bed block is provided on only one side of the frame and the other side is provided with at least two bearings configured as open shells corresponding to the positions. Since the spinning rollers only have a low rotational speed, the bearing of the spinning roller journal is enough for one open shell. Thus, two or more such bearing shells can be installed without difficulty.

It is recommended that their positions be located almost horizontally mutually. Thereby, it is clear that the open shell can be made about 180 degrees or more when the offset of the position is small.

In particular, it is advisable that the bed block is fixed to the frame via bolts and at least two settings by tapping are provided for bolting to this frame. Thus, different positions can be easily fixed by setting by the tapping hole.

Advantageously, the bed block also supports the drive for the spin roller outside of the bearing. Thus, no additional arrangement device may be arranged to engage the spinning roller with the drive device.

In particular, the drive device may comprise one motor and one gear.

In the warp knitting machine 1 shown there is a frame 2 supporting three spinning rollers 3, 4 and 5. Each spinning roller has two journals 6 and 7 and plates 8 and 9 defining the sleeve. As shown in Fig. 2, the diameters of the spinning rollers 3, 4, and 5 are larger, and the diameters of the spinning rollers 3 ', 4,' and 5 '(shown in dashed lines) are smaller. Can be.

On one side of the warp knitting machine, ie on the right hand side of the warp knitting machine, each journal 7 is fixed to a bed block 10 with a bearing 11 and a drive device 12. The bed block 10 is fixed to the frame by bolts 13, which bolt 13 fixes the bed block and is inserted into the tapping 14 of the frame 2. Two positions A and B are provided, respectively, provided through four tappings, where a bed block 10 may be installed.

On the other side, ie left here, the journal 6 is optionally arranged in the first open shell 15 or in the second open shell 16. The location of the shell corresponds to position A and position B.

From FIG. 2, the yarns 17, 17 ′ conveyed from the spinning roller are transferred to the work area 20 with the workpiece via the redirection rod 18 and the resilient redirection device 19. The offset between position A and position B is chosen for each spin roller as short as possible to the seal path between the turning point closest to the starting point from the spin roller sleeve.

In the case of the spinning rollers 3 and 5, a horizontal offset between the two positions is provided, and in the case of the spinning roller 4, it is provided at a horizontally inclined offset. The horizontal offset has the advantage that even when the size of the offset is small, the open shells 15 and 16 can be freely changed.

In the embodiment only two different spinning roller sizes are shown. However, two or more positions A and B may be required if additional spin roller sizes are to be taken into account.

If the smaller diameter rollers 3 ', 4' and 5 'should be inserted instead of the larger diameter rollers 3, 4 and 5, the bed block 10 on one side of the frame 2 Is dismantled and reattached to the selected position. This change is implemented at a lower installation cost.
