triangle

21,22,24 that haunts.As representative, situation about the state of haunting of the triangle 21 that haunts being switched with reference to Fig. 4 explanation.

Among Fig. 4, only show near the triangle 21 of haunting and the needle jack corresponding in the pin main body 91 of the needle tray configuration of needle-bar 8 with the triangle 21 of haunting.In addition, the bottom of needle tray is represented in the double dot dash line of the paper of Fig. 4 below, and the upper surface of needle-bar is represented in the double dot dash line of paper top.As shown in Figure 4, haunt triangle 21 at the spring 5s of the periphery that is installed in axial region 21b between triangle 21 and the plate-shaped member 12 of haunting all the time to the pin main body 91 1 side application of forces.Herein, under the situation of mountain portion 41 butts of abutting part 21p and triangular facet shown in Fig. 4 (A), the triangle 21 that haunts becomes the sinking state.Begin to make rotary body 4 rotation from this state, during paddy portion 42 butts of abutting part 21p and triangular facet, axial region 21b compares the state of Fig. 4 (A) to plate-shaped member 13 side shiftings shown in Fig. 4 (B), and the triangle 21 that haunts becomes outstanding state.Herein, the rotatable earth's axis of abutting part 21p is supported on axial region 21b, and rotation that therefore can accompanying rotation body 4 and rotating does not hinder the rotation of rotary body 4.In addition, abutting part 21p also can be the orbicule of installing at the front end of axial region 21b.Under this situation, abutting part 21p also can move on triangular facet smoothly, does not hinder the rotation of rotary body 4.

Then, for the position of rotation by rotary body 4 how to switch the

triangle

21,22,24 that haunts the state that haunts, how compound needle 9 is moved, describe based on Fig. 6.Fig. 6 (A) is the key diagram when making rotary body 4 consistent with primary importance, and Fig. 6 (B) is the key diagram when making rotary body 4 consistent with the second place, and Fig. 6 (C) is the key diagram when making rotary body 4 and the 3rd position consistency.The epimere figure of Fig. 6 (A)～(C) represents the track of leading section of pin main body 91 that everybody puts, pusher jack 92 and the position relation of air nozzle 3, hypomere figure is which position that the expanded view of side of rotary body 4 and

expression abutting part

21p, 22p, 24p are present in circumference 40, and stage casing figure represents to make the track of pin heel 91b, the 92b of cleaner when the direction of arrow moves.The position consistency of the letter of the position of the letter of expanded view and Fig. 5 (A).

At first, describe for the situation that makes rotary body 4 Fig. 6 consistent (A) with primary importance, shown in hypomere figure, paddy portion 42 butts of abutting part 21p and rotary body 4, other abutting parts 22p, 24p and mountain portion 41 butts.Under this situation, shown in the figure of stage casing, the triangle 21 that only haunts becomes outstanding state, by the triangle 21 that haunts with the pin of pin main body 91 heel 91b jack-up upward.On the other hand, the pin of pusher jack heel 92b fixed triangle 23 jack-up upward that is in outstanding state all the time.Consequently, shown in epimere figure, pusher jack 92 is by jack-up, and pin main body 91 finally is in pusher jack 92 and pin main body 91 both sides all by the state of jack-up by jack-up then.Because the triangle 22,24 that haunts in paper left side is in the sinking state, therefore called in person 91b, 92b still by jack-up by the pin of jack-up, pin main body 91 and pusher jack 92 are also still by jack-up.In addition, still keep primary importance and make cleaner when counter-rotating, all triangles 21～26 do not act on pin heel 91,92b, therefore can be with than going to the load that lacks when mobile to make the cleaner action.

Then, for making the rotary body 4 and compound needle 9 that clean consistent, the situation that rotary body 4 is changed to the second place and clean is described based on Fig. 6 (B) with primary importance.When making rotary body 4 be in the second place, abutting

part

21p, 24p and mountain portion 41 butts, abutting part 22p and paddy portion 42 butts.Under this situation, shown in the figure of stage casing, the triangle 22 that only haunts becomes outstanding state, is in by the pin of the pin main body 91 of the state of the jack-up heel 91b triangle 22 that haunted to leave behind, and is in by the pin of the pusher jack 92 of jack-up state heel 92b still by jack-up.Consequently, shown in epimere figure, pusher jack 92 is still by jack-up, and pin main body 91 is left behind.Under the situation of this second place be yet, make cleaner when counter-rotating, all triangles 21～26 do not act on

pin heel

91b, 92b, can be with than going to the load that lacks when mobile to make the cleaner action.

At last, shown in Fig. 6 (C), rotary body 4 changed to the 3rd position and when cleaning, abutting

part

22p, 24p and paddy portion 42 butts, the

triangle

22,24 that haunts becomes outstanding state.Under this situation, be in by the pin main body 91 of the state of leaving behind and still left behind, the pusher jack 92 that is in the state of being pulled on is temporarily left behind by the triangle 24 that haunts on paper right side, and triangle 23 jack-up that then are fixed are finally left behind by the triangle 24 that haunts in paper left side.Consequently, the both sides of pin main body 91 and pusher jack 92 are left behind.

As described above, carry out different actions in the pin main body 91 that each position compound needle 9 of rotary body 4 is possessed with pusher jack 92, therefore can clean the dust of accumulating near the concavo-convex and pusher jack 92 pinhock 91f of pin main body 91 concavo-convex effectively.In addition, haunt freely by making triangle, the pin that triangle is not acted on not to be needed to move is called in person, and therefore can cleaner be moved back and forth.And, in the cleaner of present embodiment, even make cleaner being gone to move under the situation of both sides' action of 91 pusher jacks 92 of pin main body, pin main body 91 and pusher jack 92 can be simultaneously by jack-up yet, and the load that cleaner is moved back and forth is less.This be because, shown in the stage casing figure of Fig. 6 (A), the position on the inclined-plane of the fixed triangle 23 of the position on the inclined-plane of the triangle 21 that haunts of jack-up pin heel 91b and jack-up pin heel 92b is not gone up in the glide direction (paper left and right directions) of cleaner and is repeated.

Herein, with reference to the order of the cleaning of Fig. 6, the situation of carrying out switching the position of rotary body with number order is illustrated, but is not limited to this order certainly.In addition, also can only use in 3 positions 1 or 2 and clean.

In addition, embodiment of the present utility model is not limited to above-mentioned embodiment, and change can suit in the scope that does not break away from purport of the present utility model.For example, the switching mechanism that haunts that switches the triangle that haunts also can constitute by the electromagnetic unit that has used solenoid etc.
