Fig. 9 is the circuit diagram of arrangements for speed regulation 30.

Arrangements for speed regulation 30 are performed such speed governing.Head in front of the door from open position up to arrive than fastening position slightly before in the process of assigned position P of (shown in d1 Fig. 1), the closing velocity of labeled door 16 is reduced to the 1st slow speed of closing velocity that produces than from locking mechanism, and the process from assigned position P to fastening position, then speedup arrives than the 1st fireballing the 2nd speed.With reference to Fig. 9, the circuit of the arrangements for speed regulation 30 of present embodiment is described, arrangements for speed regulation 30 have: generator 56; The 1st variable resistor 64, it is arranged on the output of generator 56; The 2nd variable resistor 66, itself and the 1st variable resistor 64 also connect; Change-over switch 68 and 70, it is used for switching between the 1st variable resistor 64 and the 2nd variable resistor 66; Switch switching part 72, it is arranged on (as shown in Figure 1) on the building side.This switch switching part 72 is arranged on position (opening direction) before the fastening position with labeled door 16 at a distance of the place of predetermined distance d2.To make head in front of the door when labeled door 16 when being in assigned position P when determining this predetermined distance d2, can make change-over switch 68 and 70 actions by switch switching part 72.When labeled door 16 opening and closing on the direction with respect to the switch switching part be positioned at evolution to the time, make electric current flow through the 1st variable resistor 64 by change-over switch 68 and 70, change-over switch 68 and 70 just is switched by switch switching part 72 along with labeled door 16 is each when opening and closing, and resistance value also is switched.

With reference to Fig. 5 and Fig. 7, the pressing device 18 of the blocking device 1 of present embodiment is described.

The action of explanation pressing device earlier, when labeled door 16 began to close originally, promptly, at Fig. 2, among Fig. 5, when labeled door 16 is mobile from left to right, until the position that arrives labeled door 16 shown in Figure 5, cranked rod 32 above the labeled door spring 42 that all is stretched is limited in primary position, while keeping assigned position (position of representing with solid line among Fig. 5) to close, during position before arriving full cut-off shown in Figure 5, the revolving body 38 of the long handle side of cranked rod 32 connects with turning to support 44, cranked rod 32 rotates then, accompany with it, the revolving body 40 of the short handle side of cranked rod 32 connects with support 46 with pushing, pushes labeled door 16 later on gradually.When full cut-off, labeled door 16 is urged predetermined distance, thus the pushing be arranged on peristome 3 sides every the cigarette member, make peristome fully every cigarette.

Illustrate in greater detail the action of pressing device 18, labeled door 16 is moved to closing direction (in Fig. 5 and Fig. 7 from left to right).Before labeled door 16 arrived fastening positions, be stretched spring 42 of cranked rod 32 applied power towards closing direction, is positioned on the primary position shown in Figure 5.Before head arrives fastening position in front of the door (position shown in Figure 5) of labeled door 16, be arranged on revolving body 38 on the front end of long handle 37 and be fastened on and turn to on the face of support 44.When labeled door 16 again when closing direction moves, rotating crank bar main body 31 is because of turning to the pushing force that produces with support 44 resistance springs 42 and opening for middle mind-set labeled door 16 that direction is counter to be pushed away with axis of rotation O '.That is to say that in present embodiment shown in Figure 7, cranked rod main body 31 is to revolution counterclockwise.In this process, the revolving body 40 that is arranged on short handle 39 tops connects with support 46 with pushing.

Pushing is born the power that is given by short handle 39 with support 46, but because pushing is fixed on the 2nd upper ledge 14 with support 46, so in the revolution of cranked rod 32, along with the revolving body 40 on the top of short handle 39 is urged, labeled door 16 to the opposition side of pushing with support 46, promptly, the 1st upper ledge 12 side shiftings, as shown in Figure 7, on the fastening position that labeled door 16 has been closed fully, labeled door 16 is urged on doorframe 4.In the present embodiment, labeled door 16 is pressed and is attached in front of the door on the vertical frame 8 of a side, the vertical frame 10 of door afterbody and the 1st upper ledge 12.Owing between labeled door 16 and doorframe 4, be provided with encapsulant 20, so can further guarantee the air-tight state between them.

According to shown in Figure 5, moving to position shown in Figure 7 during this, revolving

body

38,40 turns round the limit with support 44 and pushing with the face top of support 46 and moves turning to.That is to say, being accompanied by labeled door 16 moves to doorframe 4, the revolving body 38 of rotating crank bar main body 31 moves along the face with support 44 that turns to that extends as the crow flies on horizontal direction with respect to labeled door 16, in addition, the revolving body 40 of rotating crank bar main body 31, be accompanied by the revolution of rotating crank bar main body 31, move along the face of the pushing of extending with support 46 to the switching direction of labeled door 16.When arriving the fastening position (position shown in Figure 7) of labeled door 16, labeled door 16 is attached on the doorframe 4 by pressing device 18 powerful pressures, because of the frictional force between labeled door 16 and the doorframe 4, labeled door 16 can not be moved to opening direction, rotating crank bar main body 31 stops on the position shown in Figure 7.

Here, with reference to Fig. 3 and Fig. 4, the action when labeled door 16 is pressed to doorframe 4 by pressing device 18 describes.When by pressing device 18 labeled door 16 being pressed to doorframe 4, the installation bracket 26 of door guide roller 24 usefulness is that (clockwise direction in Fig. 3 and Fig. 4) turned round at the center with the joint portion with guide rail 6.But the installation bracket 26 of door guide roller 24 usefulness is connected with the installation bracket 28 of labeled door 16 usefulness in the mode of freely rotating at wraparound shaft axis O, so labeled door 16 moves to doorframe 4 under vertical sagging state.

Below, the occasion of opening labeled door 16 is described, be accompanied by moving of labeled door 16, cranked rod 32 is because the effect of extension spring 42 turns back to primary position along closing direction, therebetween, the revolving body 40 on the top of short handle 39 also leaves pushing support 46, and labeled door 16 leaves doorframe 4.

Below, with reference to Fig. 8 and Fig. 9 the action of arrangements for speed regulation 30 is described.

During beginning,, the 1st speed and the 2nd speed are set for desirable speed by the resistance value separately that the adjusting dial 69 and 71 of variable resistance 62 is regulated the 1st variable resistor 64 and the 2nd variable resistor 66 respectively.The 2nd resistance value of the 2nd variable resistor 66 will be set for bigger than the 1st resistance value of the 1st variable resistor 64, thereby makes the 2nd velocity ratio the 1st speed fast.

Be opened to open position shown in Figure 1 with handgrip labeled door 16, at this moment door guide roller 24 turns round, but by the effect of unilateral bearing 52, the revolution of door guide roller axle 48 is not passed on the gyroaxis 58 of generator 56 via major diameter belt pulley 54, endless-belt 55 and small diameter pulleys 60.Therefore generator 56 does not move.Then, when hand when labeled door 16 is decontroled, labeled door 16 moves to fastening position along guide rail 6 because of the deadweight beginning.Therefore, door guide roller 24 turns round, and via unilateral bearing 52, the revolution of door guide roller axle 48 is passed on the gyroaxis 58 of generator 56 after major diameter belt pulley 54, endless-belt 55 and small diameter pulleys 60 speedups, and generator 56 moves.When the gyroaxis 58 of generator 56 turned round in magnetic field, electrode upper reaches overcurrent uprised voltage by variable resistor, loaded load on generator 56, and gyroaxis 58 is produced brake force.This brake force is passed to major diameter belt pulley 54 from small diameter pulleys 60 through endless-belt 55, passes to door guide roller axle 48 more successively, is loading brake force in the revolution of door guide roller 24.Labeled door 16 has the trend of the walking quickened along the guide rail 6 that tilts, but the revolution of door guide roller 24 braked by this brake force, and the closing velocity of labeled door 16 is decelerated.

Below, circuit is described, on the position, the 1st variable resistor 64 makes its conducting by change-over switch 68 in the early stage.Door guide roller 24 beginning rotates also along the guide rail 6 that tilts and closes, the 1st closing velocity walking of labeled door 16 to have been slowed down by the 1st variable resistor 64.Labeled door 16 is walked to fastening position from open position, arrive in the afore mentioned rules position P at head in front of the door, the change-over switch 68 of the 1st variable resistor 64 sides becomes OFF by switch switching part 72, the change-over switch 70 of the 2nd variable resistor 66 sides becomes ON, and that the 1st variable resistor 64 becomes is invalid, the 2nd variable resistor 66 becomes effectively.Thus, generator 56 is required that bigger electric current is arranged, so the rotating braking of gyroaxis 58 is alleviated, labeled door 16 speedups are to 2nd closing velocity faster than the 1st closing velocity, the fastening position of walking always.

Next, when opening labeled door 16, in the arrival of the head in front of the door afore mentioned rules position P of labeled door 16, the change-over switch 70 of the 2nd variable resistor 66 becomes OFF by switch switching part 72, the change-over switch 68 of the 1st variable resistor 64 sides becomes ON, it is invalid that the 2nd variable resistor 66 becomes, and the 1st variable resistor 64 becomes effectively, and arrangements for speed regulation 30 are reset.As illustrating, door guide roller 24 turns round during labeled door 16 is opened, but because the effect of unilateral bearing 52, the revolution of door guide roller axle 48 is not passed on the gyroaxis 58 of generator 56 via major diameter belt pulley 54, small diameter pulleys 60.Therefore generator 56 does not move.
