Description

The weft selecting mechanism of Rapier looms

Technical field

The utility model relates to a kind of Rapier looms that is applicable to the field of weaving, and is meant a kind of weft selecting mechanism of Rapier looms especially.

Background technology

Weft selecting mechanism groundwork on the Rapier looms is that the weft yarn with the appointment of loom system refers to give the sword head of Rapier looms by the latitude that selects in the weft selecting mechanism, by weft insertion devices such as sword head, sword belts weft yarn is introduced shed open.

Weft-selecting mechanism is divided three classes usually:

The pure mechanical weft-selecting mechanism of §:

The latitude that selects of this class weft-selecting mechanism refers to that case inside is provided with electric component.The motion of selecting latitude to refer to, the motion by outside backguy is achieved usually.Select the mechanical structure of latitude case comparatively simple, it is smaller to select latitude to refer to that the volume of case can be done sometimes, so installing the free degree that may possess than higher.But select latitude to refer to the general more complicated of backguy motion that case is outer, most of high speed Rapier looms manufacturer does not generally re-use pure mechanical weft-selecting mechanism.

§ electromagnetic type weft-selecting mechanism:

The latitude that selects of this class weft-selecting mechanism refers to that case inside contains mechanical mechanisms such as selecting latitude electromagnet and cam link.The motion of selecting latitude to refer to is by to the energising of the solenoid of appointment and by selecting latitude to refer to that the mechanical assist mechanism of case inside drives the lifting of selecting latitude to refer to.This class weft-selecting mechanism only needs the rotational power synchronous with loom main shaft by the external electrical signal controlling.The latitude that selects that this power-assisted is selected refers to realize elevating movement.It is that inside is contained the mechanical transmission component of electromagnet and these drive disk assemblies and selected latitude to refer to be encapsulated in same the choosing in the latitude case that this class is selected the design feature of latitude case.Because integrated level is higher, the demand to the outside aspect machine driving is simple, so be a kind of weft-selecting mechanism form comparatively commonly used at present.

The pure electrical type weft-selecting mechanism of §:

Selecting latitude case inside that the linear electric motors or the stepper motor of particular design have been installed, selecting the latitude signal control motor directly to drive the elevating movement of selecting latitude to refer to by the outside.No longer need other outside machine power transmission.

The common feature of " electromagnetic type weft-selecting mechanism " and " electronic type weft-selecting mechanism " is to select latitude case internal mechanism complexity, selects the latitude casing long-pending bigger.The drawbacks limit that volume is bigger the installation site of weft-selecting mechanism.As shown in Figure 1, 2, the weft selecting mechanism of Rapier looms is that weft-selecting mechanism 1 is installed in this side of loom spinner now, and promptly selecting latitude case 1 is to be fixed on sword belt track 3 outsides, and it selects latitude to refer to that 2 is to point to board 4 inboards, and the casing that then selects latitude case 1 is in the face of keeping off a car personnel.

Adopt the weft selecting mechanism of said structure to have following shortcoming:

1, select the casing of latitude case to hinder the operating personnel that keep off a car to selecting the observation of latitude motion.

2, select the casing of latitude case to hinder the operating personnel that keep off a car to staplings after the operation that inserts of weft yarn.

3, select the casing of latitude case to hinder the cleaning of operating personnel of keeping off a car to clamping refuse yarn in the sword head.

For above-mentioned reasons, increased the operating personnel's that keep off a car work difficulty and working strength, and then influenced operating efficiency.

The utility model content

The purpose of this utility model is to provide the weft selecting mechanism of the Rapier looms that a kind of workman of being convenient to keep off a car observes, operates and settle accounts.

For achieving the above object, solution of the present utility model is: a kind of weft selecting mechanism of Rapier looms is to comprise selecting the latitude case and stretching placing the latitude that selects that selects outside the latitude case to refer to; Wherein this to select the latitude case be the sword belt track inboard that is fixed on board, its connection to select latitude to refer to be to point to the board outside promptly in the face of spinner's one side.

Described weft-selecting mechanism is pure electrical type weft-selecting mechanism or electromagnetic type weft-selecting mechanism.

Described weft-selecting mechanism is the electromagnetic type weft-selecting mechanism, and it is connected with the outside transmission mechanism of board main shaft by synchronous toothed belt.

After adopting such scheme, because the utility model has been made change with the conventional mounting position of the weft selecting mechanism of Rapier looms, the latitude case that selects that is about in the weft selecting mechanism is installed in board sword belt track inboard, and select latitude to point to spinner's a side, so in practical operation, can make things convenient for the spinner to select the observation of latitude motion, and then make things convenient for the spinner selecting the operation and the cleaning of latitude motion to selecting latitude to refer to.

The specific embodiment

Shown in Fig. 3,4, weft selecting mechanism of the present utility model is to make the field at the Rapier looms that uses the jacquard opening, owing to there is not the obstruction of moving components such as brown frame, in jacquard weave opening both sides, that is: commonly use the opposite of installation site, the abundant space that is fit to place " electromagnetic type weft-selecting mechanism " and " pure electrical type weft-selecting mechanism " is arranged, weft-selecting mechanism is installed in this position.That is: this comprises and selects latitude case 1 and stretch to place and select the outer latitude that selects of latitude case 1 to refer to 2 weft selecting mechanism, wherein this to select latitude case 1 be sword belt track 3 inboards that are fixed on board 4, the latitude that selects of its connection refers to that 2 is to point to board 4 outsides promptly in the face of spinner's one side.Thereby make the spinner to the observation of weft selecting mechanism more directly perceived and more convenient operation.

The utility model is to the installation requirement of weft selecting mechanism:

Owing to need not outside transmission, can directly weft selecting mechanism be installed in this position for pure electrical type weft-selecting mechanism;

, this Synchronous Transmission be received to select on the latitude case 1 from loom by synchronous toothed belt 5 and (see shown in Figure 3) because the outside transmission synchronous with main shaft need be arranged for pure sub-magnetic-type weft-selecting mechanism.
