In the periphery of enclosure body 33, the adjustable ring 38 as adjustment component is installed.Adjustable ring 38 is can be installed on the enclosure body 33 around axis CL rotation and at the irremovable state of axis direction with respect to enclosure body 33.In the lower surface 38a of adjustable ring 38 side, be provided with the slot part 38b that can take in jut 22e.The upper end that the lower surface 38a of adjustable ring 38 compares intercommunicating pore 26b is positioned at the below.The bottom of slot part 38b (upper surface when look up the below) is highly identical with the upper end of the intercommunicating pore 26b of enclosure body 33 on above-below direction.With adjustable ring 38 with its lower surface 38a and jut 22e mode in opposite directions state in circumferential location under, under the power that makes movable body 22 overcome disc spring 24 situation about being moved upward, the lower surface 38a touching of jut 22e and adjustable ring 38 stops the further rising (with reference to Fig. 5) of movable body 22.On the other hand, with adjustable ring 38 with its slot part 38b and jut 22e mode in opposite directions state in circumferential location under, under the power that makes movable body 22 overcome disc spring 24 situation about being moved upward, the slot part 33b of jut 22e and enclosure body 33 and the slot part 38b of adjustable ring 38 bottom touching separately stops the further rising (with reference to Fig. 6) of movable body 22.Just, the stop position when movable body 22 rises divides two phase change according to the circumferential position of adjustable ring 38.Therefore, in the manner, the lower surface 38a of adjustable ring 38 or the bottom of slot part 38b play a role selectively as the contact part with respect to jut 22e.
As shown in Figure 4, it is more outstanding that the periphery of head 34 is compared enclosure body 33, at this outshot mounting cup 27.Cover 27 covers head 34 from the top.The upper surface of cover 27 forms the tabular surface with axis CL quadrature, and its upper surface plays a role as the bearing surface 20a of bottle holder 20.Central part at cover 27 is penetrated with a glass hole 27a.Central part in the upper surface 22c of movable body 22 side is formed with glass installation shaft 40.Cup installation shaft 40 is coaxial with leading axle 25b.At the central part of head 34, formation is with the through hole 34b of this head 34 along axis CL up/down perforation.Cup installation shaft 40 is embedded in this through hole 34b sliding freely via lining 41.When movable body 22 is positioned at the lower end of its moving range (state of Fig. 4), the upper end of cup installation shaft 40 is positioned at the position that is roughly same level with the upper surface of lining 41.Therefore, decompression chamber, top 37 is formed between movable body 22 and the head 34 in the mode of surrounding cup installation shaft 40.Absorption glass 23 process cup hole 27a coaxial and mounting or dismounting installation freely with the upper end of cup installation shaft 40.Absorption cup 23 is by attracting the in-to-in air to produce the parts of adsorbing elastomeric material (for example rubber, elastic body) system.The diameter of the upper end of absorption cup 23 is littler than the diameter RB of the sunk part (101b is suitable with central part) of the bottom 101 of container shown in Figure 2 100.
Drop under the situation about touching with base portion 32 at movable body 22, absorption cup 23 is positioned at the identical height of bearing surface 20a of its upper end and cover 27, perhaps is positioned at and compares the position that bearing surface 20a retreats downwards.The position of the absorption cup 23 of this moment is a position of readiness.On the other hand, when movable body 22 left the rising of base portion 32 ground, absorption cup 23 was compared bearing surface 20a and is projected into the top.The position of the absorption cup 23 in the time of should giving prominence to is an absorption position.But, stop position such as Fig. 5 when movable body 22 rises and be present in two positions as shown in Figure 6.Like this, the absorption position of absorption cup 23 also changes in two stages.In other words, absorption cup 23 can switch between little overhang A shown in Figure 5 and big overhang B shown in Figure 6 from the outstanding overhang of bearing surface 20a.
For the inside from absorption cup 23 attracts air, on bottle holder 20, be provided with to attract road 45.First path 46 that attracts road 45 to possess to run through along its axis CL and the alternate path 47 that runs through along axis CL in the inside of the cup installation shaft 40 of movable body 22 in the inside of S. A. 25.Decompression chamber, bottom 35 is between first path 46 and alternate path 47.Thus, decompression chamber, bottom 35 also is utilized as a part that attracts road 45.Thus, attract road 45 with from the lower face side of bottle holder body 21 via decompression chamber, bottom 35 arrive absorption cup 23 the in-to-in mode, extend along the axis CL of cup installation shaft 40.In movable body 22, be provided with a plurality of link roads 48 that run through glass installation shaft 40 in direction with axis CL quadrature.Connect alternate path 47 and decompression chamber, top 37 via these link roads 48.Therefore, inside, decompression chamber, bottom 35 and the decompression chamber, top 37 of absorption cup 23 are connected with shared attraction road 45.As shown in Figure 3, in the lower end erection joint 18 of first path 46.Joint 18 19 is connected via pipe with cutting for valve 16.By connecting suction pump 17 and attract road 45 via cutting for valve 16, inside, decompression chamber, bottom 35 and the decompression chamber, top 37 from absorption cup 23 attracts air respectively, and their internal drop is low.
As shown in Figure 5, when attracting air in the inside from absorption cup 23 grades, along with the pressure reduction of decompression chamber, bottom 35, effect has attractive force F1 down on movable body 22.On the other hand, along with the pressure reduction of decompression chamber, top 37, effect has attractive force F2 up on movable body 22.Because decompression chamber 35,37 is connected with shared attraction road 45, so the pressure of two decompression chamber 35,37 is equal.Thus, acting on the magnitude relationship of the attractive force of movable body 22, is to be determined by the magnitude relationship with area of section axis CL quadrature decompression chamber, top 37 and area of section axis CL quadrature and decompression chamber, bottom 35.In addition, on movable body 22, effect downwards has the power that the is pressed into F3 of disc spring 24.And then, the space 32c between base portion 32 and the movable body 22 via intercommunicating pore 26b with the outside of bottle holder body 21, more particularly the periphery of enclosure body 33 communicates.Thus, space 32c remains barometric pressure and plays a role as the atmosphere opening chamber.Thus, thrust F4 on effect on the movable body 22 has by the barometric pressure generation.Therefore, if limit the area of section of decompression chamber, bottom 35 littler than the area of section of top decompression chamber 37 so that making a concerted effort up (F2+F4) greater than make a concerted effort (F1+F3) of down power, then along with decompression, effect has propulsive effort up on movable body 22.By such setting area of section,, can make absorption cup 23 move to absorption position thus from position of readiness along with the air that comes self-gravitation road 45 attracts and movable body 22 is risen.
By being moved to, absorption cup 23 compares the more outstanding absorption position of bearing surface 20a, peripheral part 101a by the bottom 101 of the bearing surface 20a support vessels 100 of bottle holder 20 makes absorption cup 23 be close to its central part 101b fully simultaneously and keeps container 100 reliably.On the other hand, under the situation of the absorption that need not container 100, as long as will attract road 45 to atmosphere opening, make the pressure of decompression chamber 35,37 rise to barometric pressure, make absorption glasss 23 turn back to position of readiness by the power of disc spring 24 and get final product via cutting for valve 16.At position of readiness, because absorption cup 23 is outstanding from bearing surface 20a, so, have and sending into respect to bottle holder 20 or absorption cup 23 advantages that can not counteract during advancing container 100.In addition, closely under the situation of contactor 100, container 100 is pulled into the below, and is pulled into the cup installation shaft 40 of movable body 22 under its antagonistic force up from absorption cup 23 at absorption cup 23.The propulsive effort up that acts on movable body 22 also comprises this antagonistic force.
In the bottle holder 20 of the manner, forming decompression chamber 35,37 up and down across movable body 22 ground, make the area of section difference of two decompression chamber 35,37 of movable body 22, thus movable body 22 is applied up propulsive effort, make absorption cup 23 rise to absorption position from position of readiness.Decompression chamber, bottom 35 is being abolished, the lower face side of movable body 22 is being set as under the situation of atmosphere opening chamber in its scope of whole, need to form with mode that gets around this atmosphere opening chamber and the attraction road that absorption cup 23 and decompression chamber, top 37 are communicated with, attract the layout on road to become complicated.For example, need arrange to attract road, this layout to become complicated that it is complicated that the inner structure of bottle holder 20 also becomes in the mode that arrives decompression chamber, top 37 via enclosure body 33 from base portion 32.With respect to this, in the bottle holder 20 of the manner, as long as from S. A. 25 through movable bodys 22 until arriving absorption cup 23, be provided with along their axis CL and attract road 45, towards decompression chamber, top 37 link road 48 is set from this attraction road 45 simultaneously and gets final product.Therefore, need not to be provided with to spread all over and attract the so circuitous mechanism in road to enclosure body 33 sides.Thereby, attract the layout on road 45 to become simply, and then the inner structure of bottle holder 20 become simple.
According to the bottle holder 20 of the manner,, absorption cup 23 is changed from the outstanding overhangs of bearing surface 20a by circumferentially operating adjustable ring 38.Thus, stop position, absorption position during the rising that can switch absorption cup 23 according to the amount of recess of the central part 101b of the bottom 101 of container 100 can be more reliably and stably keep bottom 101.In addition, can divide two stages to switch absorption position as mentioned above, but, can make absorption position divide three phases or its above phase change by the different multiple slot part 33b of the degree of depth is set.Perhaps, if become outer screw section in the peripheral shape of enclosure body 33, the interior all negative thread portions that forms at adjustable ring 38 make their intermeshing words, and the height of the lower surface 38a of adjustable ring 38 is changed continuously, can make the stepless variation of absorption position.
Absorption cup 23 is moved under the situation of absorption position from position of readiness, and more near absorption position, the amount of compression of disc spring 24 just increases more, and it is big more that their recuperability just becomes.Thus, along with the absorption cup 23 central part 101b near container 100, the ascendant trend of absorption cup 23 dies down, and the impact when absorption cup 23 joins with the 101b of container center portion obtains relaxing.On the other hand, owing to will adsorb cup 23 when absorption position turns back to position of readiness, begin decline from the state absorption cup 23 of the recuperability maximum of disc spring 24, so, the initial stage acceleration/accel of absorption cup 23 is big, can promptly remove the maintenance by absorption cup 23 containers that carry out 100.
