Background technology

As the technology relevant to the beating device of loom as described, the device recorded in patent document 1 can be exemplified.In patent document 1, disclose the beating device of the loom possessing the rocker formed by solid pole.Specifically, at patent document 1 open in the beating device shown, possess swing part, this swing part comprises: formed by solid pole and length direction towards the rocker in fabric width direction; Be arranged on multiple lay swords of the upside of rocker; Be supported on the reed retaining member of the upside of rocker by multiple lay sword, swing part with the axle center of rocker for oscillation center and by wobble drive.

But in the beating device disclosed in patent document 1, based on following reason, the supporting structure that there is rocker becomes complicated problem.

In the beating device of loom, swing part is driven by high speed swinging and swing part is subject to the impact caused because reed hits fell when beating up, and therefore requires that rocker has higher flexural rigidity.And, in order to improve the flexural rigidity of rocker, need the external diameter increasing rocker.But in the beating device disclosed in patent document 1, rocker is formed as solid, if therefore increase diameter, the quality of rocker can be caused to become excessive, the inertia of the rocker during swing of swing part can hinder wobble drive.Therefore, in the such solid rocker disclosed in patent document 1, the external diameter of rocker cannot be made to increase to the degree of the flexural rigidity needed for the oscillating motion obtaining swing part, thus the flexural rigidity of rocker is not enough.

But, when being in the state of flexural rigidity deficiency of rocker, during the reversion of the direction of motion (swaying direction) in the oscillating motion of swing part, time of beating up etc., because of swing part inertia, beat up time impact cause rocker to bend, therefore, exist infringement swing part oscillating motion accurately and cause institute woven fabric quality reduction situation.

Herein, in the beating device that rocker is as disclosed in Patent Document 1 formed by solid pole, become flexural rigidity in order to make up rocker not enough and suppress the flexure of rocker, and the centre position on fabric width direction is provided with the structure of the intermediate supporting device of supporting rocker.But in the structure arranging such intermediate supporting device, the supporting structure of rocker becomes complicated.

On the other hand, as the beating device of the structure of the rocker loom different from the structure disclosed in described patent document 1 itself, there is the device disclosed in patent document 2.In the beating device disclosed in this patent document 2, rocker is formed as hollow cylinder shape.And, according to such beating device (hereinafter also referred to as " beating device of cylinder type ") that have employed the rocker of hollow cylinder shape, based on following reason, the flexural rigidity of rocker can be improved, thus the supporting structure of rocker can be simplified.

Generally speaking, with regard to shaft component, the area (quality) of the section on direction orthogonal to the longitudinal direction is identical, the structure that the shape of described section is set to the large shape of distance apart from the axle center of shaft component is compared with the described structure apart from little shape, flexural rigidity is high, and shaft component not easily bends.Therefore, with regard to shaft component, when identical in quality, be formed as the structure of hollow cylinder shape compared with the structure formed with solid pole, the shape of described section can be set to the larger shape of described distance, thus can flexural rigidity be improved.

Therefore, in beating device, the such rocker disclosed in patent document 2 is formed as the structure of hollow cylinder shape compared with the solid rocker disclosed in patent document 1, does not increase quality (inertia) and can improve the flexural rigidity of rocker.And, in the beating device of such cylinder type, owing to can improve the flexural rigidity of rocker as described, therefore the supporting structure of rocker is without the need to being set to the structure possessing intermediate supporting device as the beating device of patent document 1, and can be set to comparatively simple structure.

Patent document 1: Japanese Unexamined Patent Publication 2005-344223 publication

Patent document 2: Japanese Unexamined Patent Publication 8-49140 publication

But, in the beating device of cylinder type in the past, there is following such problem.

Generally speaking, beating device becomes following structure, that is, multiple lay sword is arranged on rocker at spaced intervals on fabric width direction, and reed retaining member in the position relative to the top side of rocker to install across the mode on multiple lay sword.In addition, in beating device in the past, rocker is arranged with the configuration mode that its axle center is consistent with the oscillation center of swing part.

Therefore, in beating device in the past, with regard to comprising the swing part of rocker, multiple lay sword, reed retaining member, the position of its center of gravity is positioned at the position in the axle center (reed side) by the top than rocker, and the state (so-called non-equilibrium state) that the position becoming the center of gravity of swing part is different from the oscillation center (position in the axle center of rocker) of swing part.Therefore, along with the oscillating motion of swing part, because described non-equilibrium state causes the support of rocker to vibrate.And this vibration can encourage the vibration of loom, produce noise because of this vibration, according to circumstances can cause the damage of the device on loom.In addition, the larger described vibration of the running speed of loom is more obvious.

At this, also as disclosed in patent document 2, in beating device in the past, the counterweight at reverse reed side relative to rocker with center of gravity being set at swing part, improving described non-equilibrium state by making the position of the center of gravity of swing part entirety close to the mode of the oscillation center of swing part.

But, in the beating device of cylinder type in the past, rocker as described for improving rigidity is implemented large footpath, when therefore arranging the structure of counterweight as described on swing part, becomes the structure that there is counterweight in the position of the oscillation center away from swing part.Therefore, when being set to the structure arranging counterweight as described in the beating device of cylinder type in the past, beating device can be caused to maximize, the beating device that can swing to configure swing part needs larger space (space).

But, in loom, because of with the relation of the configuration of other devices that is equipped with in loom, often there is the situation being difficult to the space expanded for configuring beating device.Therefore, have employed in the beating device in the past of the rocker of hollow cylinder shape to improve for the purpose of rigidity, there is the situation that described counterweight cannot be set, thus in order to alleviate described vibration, have to the running speed of loom to suppress very low.In addition, also can consider to reduce the diameter of rocker and counterweight is set, but, in this case, identical with described solid rocker and rigid requirements cannot be met, thus have to make the supporting structure of rocker complicated.

Summary of the invention

To this, problem of the present invention have employed the beating device that can improve the loom of described non-equilibrium state in the beating device of the loom of the rocker of hollow cylinder shape when not making larger-scale unit for providing a kind of in order to avoid the complicated of device.

[invention effect]

According to the beating device of loom of the present invention, have employed in the beating device of the loom of the rocker of hollow cylinder shape in order to avoid the complicated of device, fixing structure on the driving shaft by being set to the rocker position eccentric to reed retaining member opposition side relative to the axle center of driving shaft in axle center, the position of the center of gravity of the swing part comprising rocker, multiple lay sword and reed retaining member can be made close to the position as the axle center of the driving shaft of the oscillation center of swing part.Therefore, according to the present invention, with regard to this beating device, even if do not arrange counterweight can improve described non-equilibrium state yet, therefore, it is possible to avoid the maximization of the device caused because arranging counterweight, even if in the loom that the configuration of beating device is limited, the vibration of loom also can be suppressed, thus can adapt to running up of loom.

In addition, in the beating device of described loom of the present invention, for following structure, namely, in eccentric relative to the axle center in the axle center of rocker and driving shaft position, the chimeric reference pins be arranged on driving shaft and rocker is set, rocker is assembled on the driving shaft in the mode freely of the axis rotation around reference pins, and the holding section that the rocker of opposing connection reference pins rotation displacement carries out supporting is arranged on a side of rocker and driving shaft, thus, the eccentric structure that can realize for the state making rocker be in eccentric relative to driving shaft by simpler structure, and can easily carry out rocker assembling operation on the driving shaft.Particular content as mentioned below.

As the eccentric structure of the state making rocker be in eccentric relative to driving shaft, such as, can consider to form in such a way, namely, coupling member rocker and driving shaft linked is set, and links this coupling member in the position that rocker is relative to driving shaft eccentric.But in the case of such a construction, need picture like that at the coupling member of different positions link driving shaft and rocker, in addition, this coupling member also requires complexity in making aspect.

To this, as the structure of structure facilitation that can make described eccentric configuration, can consider, a side in rocker and driving shaft arranges following holding section, described holding section is supported the deadweight of rocker by the opposing party in rocker and driving shaft, at this by the position making rocker be in eccentric relative to driving shaft under the state that supports, by this holding section, rocker is located relative to driving shaft, in this condition by rocker assembling on the driving shaft.

According to this structure, only (form in side's setting holding section as described of rocker and driving shaft, or install), and the structure of rocker and driving shaft being assembled is set, therefore, compared with the situation of described coupling member is set, the structure of described eccentric configuration can be made simple.And according to this structure, abutting thus making rocker locate relative to driving shaft by holding section and described the opposing party, can be set to the size of predetermined regulation thus relative to the offset in the axle center of driving shaft by the axle center of rocker.

But, in the case of such a construction, under the state supported by means of only the deadweight of holding section to rocker, although offset reaches the size of regulation, but rocker may not become the phase place of regulation relative to the phase place of driving shaft, thus there is rocker and assemble the situation needing to expend man-hour relative to driving shaft.It should be noted that, the phase place of regulation alleged above refers to, the most progressive position of the reed supported by rocker is in corresponding to the such phase place in the position of woven regulation.

Specifically, be described for the situation being provided with holding section in drive shaft side, by loading rocker on holding section, thus become the state of the deadweight engaged part supporting of rocker, but in the structure merely loaded, rocker is in the state may taking arbitrary phase place relative to driving shaft, therefore, need to carry out to make the operation of the phase place of rocker and the phase bit-by-bit of described regulation after mounting.Therefore, rocker is needed to expend man-hour relative to the assembling of driving shaft.

It should be noted that, under the state becoming the phase place of described regulation at rocker, the position of the regulation that rocker becomes on outer peripheral face is connected to the state of the specific position on holding section.Therefore, in the operation making described phase bit-by-bit, be placed in after on holding section by rocker, the mode of the state abutted in the described specific position of holding section with the position becoming the described regulation on the outer peripheral face of rocker, rotates by making rocker and carries out.But because rocker is weight thing, therefore the operation of its phase bit-by-bit needs to expend man-hour for staff.

To this, except possessing the structure of described holding section, also reference pins is set, this reference pins is arranged on driving shaft and rocker eccentric relative to the axle center in the axle center of rocker and driving shaft position is chimeric, for rocker is assembled structure on the driving shaft in the mode rotated freely around reference pins, thus become rocker because of the state from the engaged part supporting to downside rotation displacement of recoil reference pins, thereby, it is possible to become rocker all the time with the state that the phase place of regulation is located relative to driving shaft.

Specifically, reference pins is as described set, and become rocker is assembled into the structure rotated freely relative to reference pins, thus rocker because of deadweight around reference pins rotation displacement, described holding section and described the opposing party abuts thus rocker becomes the state supported by described holding section.Now, rocker is with constant track rotation displacement, and therefore described holding section and described the opposing party abut in the constant position circumferentially centered by the axle center of reference pins all the time.That is, holding section abuts in constant position all the time with described the opposing party.Therefore, become the structure that described reference pins is set, become the structure of being located relative to driving shaft by rocker by holding section thus and make the structure of described eccentric configuration simple, and except by means of only except the effect making holding section abut with described the opposing party just can to obtain the offset specified, the effect of the state that the phase place that makes rocker become all the time to specify is located relative to driving shaft can be obtained, therefore, it is possible to easily carry out the operation of being assembled relative to driving shaft by rocker.

About rocker 17 and the driving shaft 11 with described such connecting structure, under the state that rocker 17 becomes described link phase place at driving shaft 11, be positioned at the phase place of described regulation with described carrying state and be linked to driving shaft 11, the structure of described rocker 17 is located as the phase place for specifying with it, except structure described above, also be provided with reference pins 22, this reference pins 22 is arranged on driving shaft 11 and rocker 17 eccentric relative to the axle center of rocker 17 and driving shaft 11 position is chimeric, and relative to driving shaft 11, rocker 17 is linked for rotating (rotating freely).

Therefore, the flange part 18 of rocker 17 and the flange part 13 of driving shaft 11 define for the chimeric installing hole inserted of this reference pins 22.It should be noted that, in the present embodiment, installing hole on the flange part 13 of driving shaft 11 is arranged at, under the state that driving shaft 11 becomes described link phase place, with the configuration mode being positioned at the heald frame opposition side in general horizontal direction relative to the axle center 23a of driving shaft 11, be formed in and be configured with in the described imaginary circle of internal thread hole 21.In addition, the installing hole on the flange part 18 of rocker 17 is formed at, when observing from the axis direction of rocker 17, in the described imaginary circle that the through hole 26 passed for set bolt 20 configures with the described unduplicated position of through hole 26.Therefore, rocker 17 and driving shaft 11 are being installed on reference pins 22 in two installing holes by chimeric and by under the state that links, both axle center 23a, 24a can be being made consistent.And, the configuration of installing hole in described imaginary circle on the flange part 18 of rocker 17 is determined according to following content.

First, as prerequisite, the relation of the outside dimension of the internal diameter size of the connecting hole 14 on the flange part 13 of driving shaft 11 and the flange part 18 of rocker 17 is to obtain considering that the mode of the position of centre of gravity of described swing part and the described eccentric amount e needed for determining sets.Namely, due to the outside dimension of the internal diameter size of the connecting hole 14 of driving shaft 11 and the flange part 18 of rocker 17 difference 1/2 become described eccentric amount e, therefore, in 1/2 of this difference mode equal with required described eccentric amount e, such as, the internal diameter size of the connecting hole 14 of the outside dimension of the flange part 18 relative to rocker 17 is determined.

And, under the state that the relation of the described imaginary radius of a circle distance of reference pins 22 (the axle center 24a apart from) and the internal diameter size of connecting hole 14 of driving shaft 11 and the appearance and size of the flange part 18 of rocker 17 determines, the phase place of (the being in described carrying state) rocker 17 during link is specified by the configuration of the reference pins 22 in the described imaginary circle of the flange part 18 of rocker 17.Wherein, the configuration that to be configured to the position of lay sword 10 be benchmark of this reference pins 22.

Herein, for the installing hole on the flange part 18 of rocker 17, rotatably linked relative to driving shaft 11 by reference pins 22 at rocker 17, and under the state (described carrying state) that flange part 18 is connected to the connecting hole 14 of driving shaft 11 with the rotation produced because of its deadweight, become the mode of the phase place of described regulation with the phase place of this rocker 17, determine the configuration in described imaginary circle.

Its result is, under the state that driving shaft 11 becomes described link phase place, such as, make by reference pins 22, both to be linked under the axle center 23a of driving shaft 11 state consistent with the axle center 24a of rocker 17, from this state, rocker 17 is made centered by the position of reference pins 22, to rotate (swing) by deadweight and be set to the state abutted with the inner peripheral surface 15 of the connecting hole 14 of driving shaft 11, the phase place of rocker 17 is determined with the described position abutted by reference pins 22 thus, thus becomes the phase place of described regulation.

It should be noted that, strictly speaking, the position H that the flange part 18 of rocker 17 is connected to the annulus 25 (inner peripheral surface 15 of connecting hole 14) of driving shaft 11 is in from relative to the position of slightly staggering along warp direction immediately below the axle center 23a of driving shaft 11, but when the distance of the axle center 24a of the distance of shaft centers rocker 17 of reference pins 22 is large compared with eccentric amount e, the position H of described abutting can be considered as relative to the axle center 23a of driving shaft 11 be roughly immediately below position, even if therefore setting becomes required offset as described above, also harmless relative to the aperture size of the connecting hole 14 of the appearance and size of the flange part 18 of rocker 17.

According to the beating device 1 of the loom of the present embodiment as above, carry out the operation linked relative to driving shaft 11 by rocker 17 in the following way.

First, reference pins 22 to be fitted together to its one end in the installing hole being arranged on driving shaft 11 and the other end mode outstanding to connecting hole 14 side from installing hole is arranged on driving shaft 11.And, after driving shaft 11 is set to described link phase place, assemble the flange part 18 of corresponding rocker 17 relative to the flange part 13 of driving shaft 11.

In the present embodiment, when carrying out the link operation of rocker 17 and driving shaft 11, each driving shaft 11 is under the state supported by loom frame 2, at axis direction (fabric width direction) top offset freely, on fabric width direction, the interval of the flange part 13,13 of two driving shafts 11,11 can be changed.And under the state before linking rocker 17, the mode being greater than the size on the axis direction of rocker 17 with described interval configures each driving shaft 11.Therefore, in this condition, rocker 17 can be configured between two driving shafts 11,11 (flange part 13,13).

In this condition, by lift transport device carrying rockers 17 such as elevators, rocker 17 is configured at its axle center 24a such position roughly consistent with the axle center 23a of driving shaft 11 when observing from fabric width direction, and between the flange part 13,13 being configured at two driving shafts 11,11.In addition, in the configuration, rocker 17 becomes the position that is formed in the installing hole on flange part 18 when observing from fabric width direction and the roughly consistent such phase state in position of installing hole (the chimeric reference pins 22 be arranged in installing hole) of driving shaft 11 becoming described link phase place.

Then, as be configured in the position between two driving shafts 11,11 at rocker 17 state under, make each driving shaft 11 to inner side (rocker side) displacement in fabric width direction, another side of the reference pins 22 be arranged on each driving shaft 11 is set to the installing hole contraposition relative to the end being formed in side corresponding to rocker 17 (flange part 18) and the chimeric state inserted.Thus, rocker 17 becomes the state be assembled on driving shaft 11 by reference pins 22.Wherein, under the state of this assembling, rocker 17 becomes and can rotate around reference pins 22 relative to driving shaft 11.Herein, to described lift transport device to make the mode of rocker 17 displacement downwards operate time, rocker 17 rotates downward centered by reference pins 22 because of its deadweight, be connected to the inner peripheral surface 15 of the connecting hole 14 of the flange part 13 of driving shaft 11 at the outer peripheral face of flange part 18, and become the state of the inner peripheral surface 15 being positioned in this connecting hole 14.

It should be noted that, under this carrying state, the axle center 24a of rocker 17 relative to the eccentric amount e of the axle center 23a of driving shaft 11 based on the relation of the external diameter of the diameter of the inner peripheral surface 15 of the connecting hole 14 of described driving shaft 11 and the flange part 18 of rocker 17, and become the required offset of the center of gravity considering swing part, in addition, the phase place of rocker 17 by the configuration of described reference pins 22, and becomes the phase place of described regulation.And, under this carrying state, become the state of the position consistency of the position of each through hole 26 be arranged on the flange part 18 of rocker 17 and the internal thread hole 21 of corresponding driving shaft 11, therefore by by set bolt 20 through in each through hole 26 and spiral shell be contained on internal thread hole 21, thus rocker 17 links with driving shaft 11 state becoming and link and fix by flange.

Like this, according to the beating device 1 of the loom of the present embodiment, because the rocker 17 of hollow cylinder shape is linked to driving shaft 11 in the position that the axle center 23a relative to driving shaft 11 is reed retaining member opposition side bias downwards, therefore the position of the center of gravity of the swing part be made up of rocker 17, multiple lay sword 10, reed retaining member 9 and reed 8 is become close to the state as the position of the axle center 23a of the driving shaft 11 of its oscillation center, thus counterweight is not set, just can improve the non-equilibrium state caused because the position of the center of gravity of swing part is different with the position of oscillation center.

And, for rocker 17 is set to eccentric configuration relative to the state of driving shaft 11 bias to be formed in connecting hole 14 on the flange part 13 of driving shaft 11, the flange part 18 of rocker 17 formed for main body, for simple structure, favourable on therefore in manufacture view, cost.

In addition, only the flange part 18 of rocker 17 is set to relative to the connecting hole 14 of driving shaft 11 eccentric state that carrying state just can realize as described, therefore the operation for rocker 17 and driving shaft 11 being linked easily is carried out, and the eccentric amount e under this eccentric state is determined according to the relation of the appearance and size of the internal diameter size of the connecting hole 14 of driving shaft 11 and the flange part 18 of rocker 17, therefore, it is possible to easily realize the structure for obtaining the offset considered needed for the center of gravity of swing part.

But, in structure as described, the state be only set on the inner peripheral surface 15 of the connecting hole 14 by the deadweight of rocker 17, the flange part 18 of rocker 17 being positioned in driving shaft 11 also can be set to eccentric state as described, but under being only the state merely loaded, eccentric amount e becomes required size, but about the phase place of rocker 17 relative to driving shaft 11, because rocker 17 can take arbitrary phase place relative to driving shaft 11, therefore need the rocker 17 as weight thing is rotated and the operation of contraposition (adjustment) phase place with the state of mounting as described after described mounting, thus there is the situation that rocker 17 needs to expend man-hour relative to the assembling of driving shaft 11.

In addition, under the carrying state only based on the deadweight of rocker 17, due to the frictional resistance produced between the inner peripheral surface 15 of the connecting hole 14 at driving shaft 11 and the outer peripheral face of the flange part 18 of rocker 17, in the inner peripheral surface 15 of the connecting hole 14 of driving shaft 11, the position H that the flange part 18 of rocker 17 abuts may not become the lowest point of inner peripheral surface 15, even if therefore carry out the operation of phase bit-by-bit as described, the phase place that there is rocker 17 does not become the situation of the phase place of described regulation relative to the described link phase place of driving shaft 11 yet, thus there is it and regulate the situation that expends man-hour further of needing.

Namely, under the carrying state of the deadweight based on rocker 17, originally in the inner peripheral surface 15 of the connecting hole 14 of driving shaft 11, the position H that the flange part 18 of rocker 17 abuts should become the lowest point of described inner peripheral surface 15, therefore described adjustment be in by the flange part 18 of rocker 17 be connected to this lowest point state premised on carry out, but, in fact the frictional resistance owing to producing between the inner peripheral surface 15 of the connecting hole 14 of driving shaft 11 and the outer peripheral face of the flange part 18 of rocker 17 also can become the deadweight of rocker 17 by the state supported, therefore exist in the connecting hole 14 of driving shaft 11, the position H that rocker 17 abuts becomes the situation of the position of staggering from described lowest point.In this situation, even if carry out described adjustment in this condition, become rocker 17 does not become the phase place of described regulation state relative to the phase place of the described link phase place of driving shaft 11, therefore stop position is not in suitable position, and needs to regulate again.

To this, as described by arranging the chimeric reference pins 22 be installed in the installing hole of driving shaft 11 and the installing hole of rocker 17 in the position relative to the axle center 24a of rocker 17 and the axle center 23a bias of driving shaft 11, by being configured to the structure of rotatably being assembled around reference pins 22 relative to driving shaft 11 by rocker 17, thus the flange part 18 of rocker 17 is all the time with constant track rotation displacement, the inner peripheral surface 15 of the connecting hole 14 of driving shaft 11 abuts in the constant position (specific position) circumferentially centered by the axle center of reference pins 22 with the outer peripheral face of the flange part 18 of rocker 17, in the inner peripheral surface 15 of the connecting hole 14 of driving shaft 11, the position H that the flange part 18 of rocker 17 abuts becomes constant position all the time.

And, the chimeric installing hole inserted of confession reference pins 22 on rocker 17 is formed as, under the state of the described constant position abutting of outer peripheral face in the inner peripheral surface 15 of the connecting hole 14 of driving shaft 11 of the flange part 18 of rocker 17, the position of rocker 17 is made to become the such configuration of the phase place of described regulation mutually, therefore be only set to by rocker 17 and rotated centered by the position of reference pins 22 by deadweight and be connected to the state of the inner peripheral surface 15 of connecting hole 14, the phase place just becoming rocker 17 is in the structure of the phase place of described regulation.Therefore, according to the beating device 1 of the present embodiment, in the assembling operation of rocker 17 relative to driving shaft 11, can not carry out the operation of phase bit-by-bit as described, therefore described assembling operation becomes and can easily carry out.

In addition, in the present embodiment, under the state that driving shaft 11 becomes described link phase place, the position of reference pins 22 is in relative to the position on axle center 23a general horizontal direction (roughly warp direction) of driving shaft 11, thus becomes reference pins 22 and to be positioned at the axle center 24a of rocker 17 relative to the eccentric direction (relative to the axle center 23a of driving shaft 11 to the direction of reed retaining member opposition side) of the axle center 23a bias of driving shaft 11 with the structure in the direction of the angular cross of roughly 90 °.Thus, the direction (eccentric direction) the axle center 24a of rocker 17 and the position H of driving shaft 11 linked is roughly consistent with gravity direction, and the power acting on the position H of driving shaft 11 (inner peripheral surface 15 of connecting hole 14) because of the deadweight of the rocker 17 under described carrying state is almost consistent with the gravity acting on rocker 17.Therefore, according to the beating device 1 of the present embodiment, because the rocker 17 of described carrying state is located more reliably relative to driving shaft 11, therefore described assembling operation can more easily and carry out more accurately.

Above, be illustrated, but beating device of the present invention is not limited to described embodiment to an embodiment of the beating device of loom of the present invention, the example of following distortion also can be implemented.

About holding section, in the described embodiment, connecting hole 14 for forming holding section is formed in driving shaft 11, and become (following when rocker 17 being assembled in the operation of driving shaft 11, also referred to as " during assembling "), the flange part 18 of rocker 17 is loaded (supporting) structure on the inner peripheral surface 15 of the connecting hole 14 of driving shaft 11, but connecting hole also can be formed on rocker, the structure on the flange part of driving shaft also can be positioned in the inner peripheral surface of its connecting hole for rocker.That is, beating device of the present invention is not limited to the holding section setting structure on the driving shaft supported the deadweight of rocker when rotating centered by reference pins, also can be the structure that this holding section is arranged on rocker.

Specifically, such as, the structure shown in Fig. 3 can be enumerated as one example.The structure of this Fig. 3 is, in the structure that driving shaft and rocker as described embodiment are linked by flange and directly link, the flange part of driving shaft does not form connecting hole, the structure that the flange part of rocker is formed connecting hole of replacement.Specifically, in this example, the flange part 38 of rocker 37 is formed to make the center of the connecting hole 34 in the aperture larger than the outside dimension of the flange part 33 of driving shaft 31 mode consistent with the center (axle center of rocker 37) of flange part 38.Therefore, the flange part 38 of rocker 37 has the outside dimension that can form such connecting hole 34.In addition, by forming such connecting hole 34, thus the flange part 38 of rocker 37 becomes the structure had from the discoid base portion annulus 39 outstanding to cylindrical portion opposition side.Thus, under the state of rocker 37 in the connecting hole 34 of annulus 39 flange part 33 of driving shaft 31 being configured at this flange part 38, the structure being positioned in the state on the outer peripheral face of the flange part 33 of driving shaft 31 with the inner peripheral surface 35 of this connecting hole 34 can be become.

And, according to this structure, rocker 37 becomes the state be positioned in the inner peripheral surface 35 of the connecting hole 34 of the annulus 39 of this flange part 38 on the outer peripheral face of the flange part 33 of driving shaft 31, and rocker 37 becomes the state supported to the state driven shaft 31 that downside (reed retaining member opposition side) is eccentric relative to the axle center of driving shaft 31 with its axle center thus.Therefore, in the structure shown here, the part (part for upside) being connected to the inner peripheral surface 35 of the connecting hole 34 of the outer peripheral face of driving shaft 31 under being included in described carrying state plays function in a part for annulus 39 that is interior, flange part 38 as holding section.

In addition, about holding section, in described embodiment and described example, by driving shaft and rocker a square one-tenth connecting hole thus formed holding section, specifically, a part for the annulus of the flange part arranged by forming connecting hole in one is equivalent to holding section, but, holding section be not limited to as the structure that formed by connecting hole, also can be configured to, relative to the flange part of one, at the part place circumferentially of its end face, the jut outstanding to the opposing party side of driving shaft and rocker from this end face.Namely, in the structure of described embodiment, annulus 25 is present in whole mode circumferentially with perisporium and arranges, but what play function as holding section is the part of this perisporium, therefore also can be set to and only there is the part of this perisporium as jut and structure that other part eliminates.

Specifically, such as, be provided with in the structure of holding section at driving shaft as described embodiment, following structure can be set to, namely, relative to the end face of the rocker side of the discoid flange part of driving shaft, a part in a circumferential direction and be equivalent to the position of the holding section of the annulus in described embodiment, installs fastened component as described jut to give prominence to such mode from described end face.And in this case, this fastened component becomes the holding section of driving shaft.

It should be noted that, about this fastened component, can be the component be made up of the sheet material of arc-shaped as a part for the annulus in described embodiment, as long as the deadweight of the rocker that winding reference pins is rotated can be propped up in holding section, therefore also can be the component of pin shape etc.In addition, about the position of this fastened component, be not limited to the structure being arranged on the position identical with the holding section (part for annulus) in described embodiment as described, as long as under the state being connected to this fastened component (jut) at the rocker rotated around reference pins and supporting deadweight, the described eccentric amount e of rocker becomes required size and the phase place of rocker becomes the structure of the phase place of described regulation, just can be arranged on arbitrary position.

In addition, about the relation of the opposing party be arranged in the holding section of one and driving shaft and rocker, in the described embodiment, when described assembling, become rocker 17 and be positioned in structure on the inner peripheral surface 15 of the connecting hole 14 of driving shaft 11 at the outer peripheral face place of its flange part 18.Namely, described the opposing party is set to by mounting surface with the best part of its outside dimension, when described assembling, become described the opposing party in such structure being supported on the holding section of one by mounting surface place, accompany with it, in order to realize described eccentric state, described holding section is arranged on axle center to the position of the described distance large by the distance of mounting surface than described the opposing party on the radial direction of one.But, the holding section of the one in the present invention and the relation of described the opposing party are not limited to such relation, also can be set to when described assembling, load the structure of (supporting) in the engaged part, part place by the inner side on radial direction compared with the outside dimension the best part of described the opposing party.And, in this case, about the position of the holding section on the radial direction of one, described eccentric state can be obtained in such mounting.

Specifically, such as, identical with described embodiment, described the opposing party is set to rocker, when described assembling rocker at flange part place by the structure that is positioned on the holding section of driving shaft, consider as shown in Figure 4, the flange part 48 of rocker 47 arranges the concentric protuberance 49 less than the outside dimension of described outer peripheral face in the mode of giving prominence to from the end face of its drive shaft side, namely, flange part 48 is set to the structure with step, and the structure etc. supported in the holding section of this stage portion (outer peripheral face 50 of described protuberance 49) place's driven shaft 41.And in the case of such a construction, when making the eccentric amount e under required described eccentric state identical with described embodiment, the connecting hole 44 of driving shaft 41 is arranged on the inner side on the radial direction of driving shaft 41 compared with described embodiment.But, in either case, the position of the holding section on the radial direction of one be arranged at the distance of shaft centers of described the opposing party at that time by the position away from the axle center of one compared with the distance of mounting surface, this position is determined with required described eccentric amount e by the described distance of described the opposing party.

It should be noted that, in the example of fig. 4, described protuberance 49 is formed as drum, but described protuberance 49 is not limited to such structure, as long as described assembling time can load described the opposing party by the shape of mounting surface, just can be arbitrary structure.

About reference pins, in the described embodiment, under the state that driving shaft 11 becomes described link phase place, be arranged on and the end face (end face of flange part 13) of the rocker side of driving shaft 11 is in the position of the heald frame opposition side of general horizontal direction and the position be configured with in the described imaginary circle of internal thread hole 21 relative to the axle center 23a of driving shaft 11, but the position of reference pins on the described end face of driving shaft is not limited to the position of described embodiment, as long as meet following condition, it just can be arbitrary position.

First, by reference pins rocker rotated freely under the state being assembled in driving shaft, going up in the relation of installing hole (the chimeric hole the being inserted with reference pins) position on rocker formed with the end face (end face of flange part) of the drive shaft side on rocker, when observing from fabric width direction, be set to the position consistency in the position in the axle center enabling rocker and the axle center of driving shaft.In other words, make the distance of the distance of shaft centers installing hole on the distance of the distance of shaft centers reference pins on the described end face of driving shaft and the described end face of rocker consistent.

In addition, under the state as described driving shaft and rocker assembled, the consistent state in axle center both when fabric width direction is observed rises to be needed to make rocker pass through deadweight and can rotate, therefore, under the state becoming described link phase place at driving shaft, axle center is positioned at the position beyond position on the imaginary line that extended in vertical direction by the axle center of driving shaft, top side compared with the axle center of driving shaft.

And, under the rocker state that engaged part supporting is conducted oneself with dignity around the rotation of this reference pins, become the mode of required size relative to the eccentric amount e in the axle center of driving shaft with the axle center of rocker, in the relation of the position with holding section, the amount of spin that can obtain the such rocker of required described eccentric amount e as described from the consistent state in both axle center can be obtained.

In addition, in described embodiment and described example, be provided with reference pins driving shaft and rocker linked for rotating, when described assembling, rocker is rotated by deadweight centered by reference pins relative to driving shaft, its phase place of rotating engaged part supporting (locking) and carrying out rocker determines (becoming the state of the phase place of described regulation), but in beating device of the present invention, not necessarily this reference pins, when described assembling, rocker can by means of only holding section supporting deadweight.

Specifically, such as, identical with described embodiment, one is set to driving shaft, driving shaft possess holding section and rocker when the end face of drive shaft side possesses the structure of flange part, when described assembling, rocker can only be positioned on the holding section of driving shaft at flange part place.And, even such structure, the state of the axle center that also can realize rocker is eccentric relative to the axle center of driving shaft required offset.It should be noted that, in the case of such a construction, the rocker under the state of engaged part supporting may take arbitrary phase place relative to driving shaft, and the phase place therefore for rocker is determined, under described carrying state, staff is by making the rotation of rocker to carry out.

About the connecting structure of driving shaft and rocker, in the described embodiment, in order to the rocker 17 under having made downwards state eccentric relative to driving shaft 11 can link with driving shaft 11, become the structure formed by following configuration, namely, multiple through holes 26 that the flange part 18 of rocker 17 passes for set bolt 20 are positioned in the imaginary circle centered by the axle center 24a of rocker 17, and correspond in imaginary circle that the internal thread hole 21 of described through hole 26 is positioned at centered by eccentric relative to the axle center 23a of the driving shaft 11 becoming described link phase place position on the flange part 13 of driving shaft 11 downwards, but, described connecting structure is not limited to such structure, also can be structure as following.

Such as, it can be the structure formed by following configuration, namely, on the flange part of driving shaft, the structure that multiple internal thread hole is positioned at the configuration in the imaginary circle centered by the position in the axle center of driving shaft and is formed, and, on the flange part of rocker, be positioned in the imaginary circle centered by relative to the position that (reed retaining member opposition side) is eccentric upward, axle center of the rocker of the phase place becoming described regulation under described carrying state corresponding to the through hole of described internal thread hole.

In addition, for the through hole corresponding with described internal thread hole, as long as set bolt can be screwed on rocker with in the internal thread hole corresponding under the state of phase place becoming described regulation of described carrying state, just can be arbitrary structure, such as, can be the structure that described through hole is formed as the hole being large footpath relative to corresponding internal thread hole, also can be that described through hole is formed as the structure of elongated hole relative to corresponding internal thread hole.When being set to these structures, without the need to making described through hole be formed in the mode of strictly position consistency relative to corresponding internal thread hole, therefore with regard to described connecting structure, its design becomes and is more prone to.

In addition, as described embodiment when beating device of the present invention is set to the structure possessing reference pins, replace the structure that described through hole is formed as circular hole, also the structure that described through hole is formed as the elongated hole of the arc-shaped centered by the axle center of reference pins (center of installing hole) can be set to, when being set to such structure, described connecting structure can be set to described carrying state by making rocker rotate around reference pins under the state be screwed on through the set bolt in described elongated hole in corresponding internal thread hole.

In addition, in the described embodiment, rocker 17 has flange part 18 at its both ends and driving shaft 11 has flange part 13 in the end of rocker side, and become driving shaft 11 with rocker 17 at respective flange part place by the structure linked, but the connecting structure of driving shaft and rocker is not limited to such structure.That is, described connecting structure also can be the structure that the mode beyond driving shaft and rocker are linked by flange links.

Specifically, such as, the structure shown in Fig. 5 can be enumerated as one example.The structure of this Fig. 5 is, the rocker replaced as described embodiment has flange part and the structure being linked by flange with driving shaft and link, and is set to rocker and does not have flange part and relative to driving shaft by the chimeric structure linked.Specifically, in this example, become following structure, that is, the end of the rocker side of driving shaft 51 is provided with coupling member 52, this coupling member 52 has the embedded hole for being linked relative to driving shaft 51 by rocker 57.

The discoid sheet material that coupling member 52 is greater than the outside dimension of driving shaft 51 and the outside dimension of rocker 57 (cylindrical portion) by outside dimension is formed, a side in its two sides is formed with the first embedded hole 53 for being installed on driving shaft 51, and another side in described two sides forms the second embedded hole 54 for installing rocker 57.First, second embedded hole 53,54 is formed as the hole with the end only in separately set side upper shed, and aperture size becomes the size corresponding with the outside dimension of the driving shaft 51 be embedded in each side and rocker 57.Wherein, the second embedded hole 54 is formed relative to the mode of the position that the first embedded hole 53 has been in eccentric with the position at center, relative to this first embedded hole 53 eccentric amount e with become with as described needed for the mode of the identical size of offset formed.

And when described assembling, coupling member 52 is in the configuration of the position of below relative to the axle center of the driving shaft 51 becoming described link phase place by the center that becomes the second embedded hole 54, the first embedded hole 53 is embedded in the rocker side end of driving shaft 51.In the example shown in the series of figures, the mode of the end face opening of the rocker side at driving shaft 51 is provided with multiple internal thread hole 55, and the bottom surface of the first embedded hole in coupling member is formed with the through hole 60 corresponding with described internal thread hole, by being screwed together in corresponding internal thread hole 55 through the set bolt 56 in this through hole 60, thus coupling member 52 and driving shaft 51 are fixed.

And the end corresponding to this driving shaft 51 side is embedded in the second embedded hole 54 of coupling member 52 by rocker 57.In the example shown in the series of figures, be formed with multiple internal thread hole 58 in the mode of the outer peripheral face upper shed of the end at rocker 57, and be formed with the through hole 61 corresponding with described internal thread hole 58 in the mode of the inner peripheral surface upper shed of the second embedded hole 54 at coupling member 52.With regard to this through hole 61, its position on described inner peripheral surface is in, and can make the position be screwed on through the set bolt 59 in this through hole 61 in the internal thread hole 58 of the correspondence of the rocker 57 of the phase place of described regulation under the described link phase place of driving shaft 51.And, when described assembling, rocker 57 is rotated staff and the phase place of carrying out rocker 57 is determined, and make the chimeric set bolt 59 be inserted in this through hole 61 screw togather with corresponding internal thread hole 58, rocker 57 becomes the state of fixing with the phase place of described regulation relative to the driving shaft 51 becoming described link phase place thus.

According to this structure, the position that second embedded hole 54 has been formed in relative to the first embedded hole 53 bias on coupling member 52, coupling member 52 fixes relative to driving shaft 51 by the configuration of position being in below with the center of the second embedded hole 54 relative to the axle center of driving shaft 51 when described assembling, and the rocker 57 be therefore embedded in the second embedded hole 54 is in the position that (reed retaining member opposition side) is eccentric, axle center relative to driving shaft 51 downwards.

It should be noted that, in this example, becoming in the embedded hole of the side side being arranged at driving shaft 51 and rocker 57 chimeric has the opposing party of driving shaft 51 and rocker 57 and is in the structure of described eccentric state.Like this, in beating device of the present invention, described connecting structure is not limited to following structure, that is, described eccentric state is become under side's movable fit of the driving shaft as described embodiment and described example and rocker carrying state in the connecting hole that the aperture size of the outside dimension being arranged on the ratio one on the opposing party in driving shaft and rocker is large.

In addition, in the described embodiment, driving shaft 11 possesses holding section, and become rocker 17 and to be positioned on holding section thus deadweight is supported, thus achieve the structure of rocker 17 relative to the eccentric state of driving shaft 11, but in beating device of the present invention, the side being not limited to driving shaft and rocker is possessed holding section and is supported the structure of the deadweight of rocker by this holding section, such as, also can be following structure, namely, link in the structure of driving shaft and rocker in the mode linked by flange as described embodiment, one does not possess holding section, under the state that rocker is eccentric relative to driving axial reed retaining member opposition side, rocker supporting driving shaft is made by means of only set bolt.That is, beating device of the present invention is not limited to the structure possessing described holding section, as long as the rocker position eccentric to reed retaining member opposition side in the position in axle center relative to driving shaft is linked fixing structure, just can be arbitrary structure.

In addition, in the beating device of described embodiment, become rocker is linked to the both sides drive-type of driving shaft structure at its both ends place, but the structure of such both sides drive-type is not limited to as the beating device of prerequisite of the present invention, also can be following structure (structure of so-called one-sided drive-type), namely, rocker is only linked to driving shaft with the end of its side, the end of opposite side is in the position in axle center and is fixedly linked on bolster with the state eccentric to reed retaining member opposition side with the size identical relative to the eccentric amount e of described driving shaft, described bolster axle center when observing from fabric width direction is consistent with described driving shaft and with the state support that can rotate in loom frame.

In addition, the present invention is not limited to arbitrary embodiment described above, can be suitable for changing in the scope not departing from its purport.
