Abstract
The invention discloses a heald lifting device on a rapier loom, wherein a weft detector used for detecting whether wefts are led in or not is arranged on the rapier loom. The heald lifting device comprises a heald lifting cutter at the head end or the tail end and also comprises a proximity switch which is arranged nearby the heald lifting cutter and only used for detecting the moving position of the heald lifting cutter, wherein the proximity switch communicates with the weft detector. When empty weft appears, the first heald lifting cutter moves to a position close to the proximity switch, the proximity switch sends a signal to the weft detector, the weft detector sends a yarn signal to an electrical cabinet and the whole machine rotates continuously and does not stop. The device can be used on an occasion when patterns on a cloth require local empty weft; and the rapier loom with the device has relatively strong adaptive capacity.
Description
Technical field
The present invention relates to a kind of heald lifting device that is applied on the Rapier looms.
Background technology
In the prior art, Rapier looms has and is used to detect the weft detector that whether has weft yarn to introduce, when empty latitude occurring, weft detector can send a no yarn signal to the main controller of complete machine, the complete machine automatic stopping, complete machine does not stop when existing some demands to require empty latitude in practice, requires local empty latitude as the floral designs on the cloth, then existing Rapier looms can't adapt to this demand, and adaptive capacity is poor.
Summary of the invention
The object of the present invention is to provide a kind of heald lifting device that is applied on the Rapier looms, this device makes that complete machine does not stop when having leisure latitude.
In order to reach above purpose, the technical solution used in the present invention is: the heald lifting device on a kind of Rapier looms, have on the Rapier looms and be used to detect the weft detector that whether has weft yarn to introduce, this heald lifting device comprises a slice shedding cutter that is in head-end location or tail end position, it also comprise be located near this sheet shedding cutter and only be used to detect this sheet shedding cutter movement position near switch, describedly communicate near switch and described weft detector.
Because the present invention has adopted above technical scheme, its advantage is: when empty latitude occurring, first shedding cutter moves near the position near switch, then send a signal and give weft detector near switch, the control weft detector sends one has the yarn signal to give electric cabinet, and then complete machine remains in operation, and can not stop, this device can be useful in the situation that floral designs on the cloth require local empty latitude, and the Rapier looms adaptive capacity with this device is stronger.
Description of drawings
Accompanying drawing 1 is looked schematic diagram for master of the present invention;
Wherein: 2, weft detector; 4, electric cabinet; 5, shedding cutter; 6, near switch; 12, cable.
The specific embodiment
Further set forth concrete structure of the present invention below in conjunction with accompanying drawing.
Shown in accompanying drawing 1, a kind of Rapier looms comprises warp-feeding mechanism, shedding mechanism, weft insertion device, beating-up mechanism, spooler, during work, electric cabinet 4 is coordinated each mechanism of control makes it come work by certain kind of drive and transmission ratios, guarantees normal woven carrying out.
Have on the Rapier looms and be used to detect the weft detector 2 that whether has weft yarn to introduce, weft detector 2 communicates with electric cabinet 4, and when empty latitude occurring, weft yarn detects 2 can send no a yarn signal to electric cabinet 4, electric cabinet 4 control complete machines parkings.
Has multi-disc shedding cutter 5 on the Rapier looms, heald lifting device on the Rapier looms comprises a slice shedding cutter 5 of being in head-end location, be located near this sheet shedding cutter 5 and only be used to detect these sheet shedding cutter 5 movement positions near switch 6, communicate by cable 12 near switch 6 and weft detector 2.Near switch 6 are infrared sensors, when first shedding cutter 5 near near switch 6 time, can output one signal near switch 6, near the position of the switch 6 shedding cutter 5 away from other sheets, the motion of the shedding cutter 5 of other sheets can not influence near switch 6.Also can only detect the motion of a slice shedding cutter 5 that is in the tail end position near switch 6, and not be subjected to the influence of other shedding cuttves 5.When empty latitude occurring, move near position corresponding to first shedding cutter 5 near switch 6, then send a signal and give weft detector 2 near switch 6, control weft detector 2 sends one has the yarn signal to give electric cabinet 4, then complete machine remains in operation, can not stop, this device can be useful in the situation that floral designs on the cloth require local empty latitude.
