Problems solved by technology

[0004] However, in the bobbin delivery device for the roving frame described in Patent Document 1, for example, when ejection occurs due to the eccentricity between the bobbin hanger and the bobbin, and foreign matter such as flying flowers gets caught in the rotating shaft, In the case of malfunction of the supporting arm caused by it, there is a possibility that the height of the supporting arm becomes unequal
If the height of the support arm is not equal, the load on the motor that drives the support arm and the rotating shaft increases, which is disadvantageous.

[0025] Below, according to Figure 1 ~ Figure 4 A first embodiment in which a bobbin delivery device for a roving frame is embodied will be described. Such as figure 1 As shown, the roving frame 10 includes an upper-supported flyer 11 , a bobbin 12 attached to the flyer 11 , and a bobbin rail 13 . A drafting unit 14 is provided on the upstream side of the flyer 11 , and the sliver 15 is drawn by the drafting unit 14 , and the roving is wound onto the bobbin 12 via the flyer 11 . Bobbin teeth 13A are arranged on the bobbin rail 13 in two rows in front and rear in a zigzag shape. The bobbin 12 includes two types: a full bobbin 12F that is wound with a roving and becomes a full bobbin, and an empty bobbin (not shown) that is not wound with a roving. exist figure 1 A full bobbin 12F that has become a full bobbin and has been removed from the flyer 11 is shown in . It should be stated that in figure 1 Here, the direction perpendicular to the longitudinal direction of the rovi...

[0056] Next, according to Figure 5 A second embodiment will be described. The present embodiment differs from the first embodiment in that a wire trip switch 58 is provided as a detection means, and other configurations are basically the same as those of the bobbin delivery device 16 of the roving frame in the first embodiment.

[0057] Such as Figure 5 As shown, the wire gate switch 58 as a detection unit consists of a wire 59 extending in the longitudinal direction of the bobbin transfer device 16, a fastening portion 60 connected to one end of the wire 59, and a switch 61 connected to the other end of the wire 59. constitute. The fastening unit 60 and the switch 61 are attached to the support arms 31 arranged at both ends in the longitudinal direction of the bobbin delivery device 16 in the same manner as the light projector 47 and the light receiver 48 of the first embodiment. The wire 59 passes through the slit 36 ​​of the support arm 31 disposed at positions other t...

Abstract

The present invention provides a bobbin transfer device for a roving frame that stops a drive system of support arms by detecting unequal heights of support arms. The bobbin transfer device (16) includes a belt (37) connected at one end to a bobbin support body (18) and wound at the other end; a belt winding unit (38) connected to the other end of the belt (37), the belt (37) being wound therearound; and a plurality of support arms (31) for guiding the elevation of the bobbin support body (18). The bobbin transfer device includes a photosensor (49) serving as a detection unit that detects an elevation difference between the plurality of support arms (31) and a stop device (57) that stops the belt winding unit (38) when the photosensor (49) detects an elevation difference between the plurality of support arms (31).

Description

technical field [0001] The invention relates to a bobbin transfer device of a roving frame. Background technique [0002] Generally, the bobbin delivery device for a roving frame and the roving frame disclosed in Patent Document 1 are known as prior art of a bobbin delivery device for a roving frame, for example. The bobbin transfer device for the roving frame disclosed in Patent Document 1 is provided with two support rails above the front side of the roving frame. track. The bobbin hanger can hang empty bobbins or full bobbins. The support rail is fixed to a plurality of support arms arranged along the longitudinal direction, and the support arms are arranged so as to be able to be raised and lowered by a lifting device. The lifting device includes: a belt whose one end is connected to the support arm and whose other end can be wound; and a rotating shaft which is connected to the other end of the belt and which winds the belt. The support arm is arranged so that it ca...
