Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for adjusting the tension of a warp of a beam received by an in-process carrying device, and a carrying device including the device.

(Prior Art) As one of the transporting devices having a delivery function for machine work, there is a transporting device disclosed in Japanese Patent Laid-Open No. 63-42944. This carrying device is provided with a carriage that can be moved to the delivery position of the warp beam, and a shaft portion of the beam so as to be rotatable around the axis line of the beam so that the axis line of the beam is horizontal.
A pair of transfer arms arranged in parallel at a distance in the horizontal direction, a drive mechanism for moving the transfer arms with respect to the carriage to transfer the beam, and a reed and a heddle through which warps extending from the beam are passed. It includes a support mechanism that supports a threading member such as a frame and a dropper device, and a tension adjusting mechanism that adjusts the tension of the warp thread extending from the beam supported by the transfer arm to the threading member. The tension adjusting mechanism of the known carrying device is operated by an operator operating a push button switch.

(Problems to be solved) However, in the known tension adjusting mechanism, since the push button switch has to be operated every time the tension of the warp changes, the work is troublesome, and the tension of the warp is visually measured. Since it is confirmed manually, the tension cannot be adjusted to a constant value.

As described in JP-B-57-53899 and JP-A-63-243353, a tension maintaining mechanism for preventing rotation of the beam supported by the beam receiving portion has been proposed. However, since this tension maintaining mechanism is a braking mechanism,
The tension must be adjusted manually, so it cannot be adjusted to a constant value.

An object of the present invention is to provide a warp tension adjusting device and a carrying device including the same, which can adjust the tension to a constant value and maintain the tension at a constant value without manual labor.

(Solution Means, Actions, and Effects) A warp tension adjusting device of the present invention is a device for adjusting the tension of a warp of a beam rotatably received by a machine tool carrier, which is parallel to the axis of the beam. An arm supported by the delivery means so as to be angularly rotatable about an axis 1, a rotation mechanism supported by the arm, and a rotation about a second axis parallel to the first axis. And a roller that is arranged so as to contact with the beam and that applies a rotational force to the beam in a direction of receiving the rotation of the rotation mechanism and winding the warp, and transmitting the rotation of the rotation mechanism to the roller. And a friction clutch disposed at.

When the beam around which the warp is wound is received by the delivery means,
The roller comes into contact with the roller and receives a rotational force in the winding direction of the warp due to the rotation of the roller accompanying the rotation of the rotating mechanism.

The warp thread extending from the beam is wound around the beam when there is slack in the warp thread. However, when the tension of the warp extending from the beam exceeds the value determined by the friction clutch, the friction clutch slips, and the rotor does not rotate. Further, when a force for pulling out the warp from the beam, that is, an excessive tension acts on the tip portion of the warp, the beam is rotated in the direction in which the warp is paid out, so that the warp is pulled out from the beam.

Thus, according to the present invention, when the tension of the warp extending from the beam is excessive or insufficient, the beam is rotated and the tension of the warp extending from the beam is adjusted to a constant value without manual labor, Maintained at that value.

Further, a rotor rotatably arranged about the second axis, another friction clutch for transmitting the rotation of the rotating mechanism to the rotor, and the transport centered on the first axis. A circular stator that is non-rotatably attached to the device, and is arranged so as to return from the stator to the stator via the rotor, and is locked to the stator so as not to be relatively movable in the circumferential direction. It is preferable to include a connected body.

Thereby, the rotor, the stator, and the coupling body act to rotate the arm in the direction in which the roller is pressed by the beam while the rotation source is rotating. Therefore, at the time of delivery, even if the beam is displaced with respect to the delivery means, since the arm is angularly rotated and the roller is always in contact with the beam, the tension of the warp thread is constant until the beam is separated from the roller. Maintained.

The rotation mechanism may include a shaft rotatably supported by the arm around the second axis, and a rotation source that rotates the shaft around the axis.
In this case, the rotor and the stator are connected to the shaft via corresponding friction clutches.

The rotor may be connected to one end of the shaft via a corresponding friction clutch and the stator may be connected to the other end of the shaft via a corresponding friction clutch. Sprocket may be used as the rotor and the stator, and an endless chain may be used as the connecting body.

The rollers are preferably arranged such that they contact the outer peripheral surface of the beam flange.

The carrying device of the present invention is a carrying device for delivering a beam around which a warp is wound to a loom or a preparation cradle, and a delivery device that is movable to a delivery position of the beam and the delivery of the beam. Therefore, the delivery means, which is arranged on the transportation means, receives the beam rotatably about its axis, the driving means for displacing the delivery means with respect to the transportation means so as to deliver the beam, and the delivery means. Means for adjusting the tension on the warp extending from the beam supported by the beam, the tension adjusting means being angularly rotatable about a first axis parallel to the axis of the beam received by the delivery means. An arm supported by the delivery means, a rotating mechanism supported by the arm, and rotatable about a second axis parallel to the first axis and in contact with the beam. A roller arranged to apply a rotating force to the beam in a direction of winding the warp in response to the rotation of the rotating mechanism, and a friction clutch arranged to transmit the rotation of the rotating mechanism to the roller.

In the illustrated example, the rack 38 and the gear 60 are different from each other in the rack 38 and the gear 60.
However, the rack 38 may be arranged on the moving base 40 and the gear 60 may be arranged on the carriage 28, respectively. In any case, since the load of the moving table 40 is received by the rail 36, the load of the moving table 40 does not act on the rack 38 and the gear 60, and the movement of the moving table 40 with respect to the carriage 28 becomes smooth.

As a mechanism for moving the moving table 40 in the front-rear direction with respect to the carriage 28, another mechanism such as a jack can be used.

As shown in FIG. 5, the sliders 80 and 82 respectively have female screws 92 and 94 screwed to the screw rods 72, respectively, so as to be rotatable around the corresponding screw rods 72. Female thread 92
And 94 are associated with the corresponding sliders by timing pulleys 96 and 98 and connectors 100 and 102, respectively.
The timing pulleys 96 and 98, which are connected to 80 and 82, are also rotated and thereby moved in the vertical direction. This allows the support 76 and
78 is also moved vertically.

Since the support bases 76, 78 are engaged with the threaded rod 72 via the female screw bodies 92, 94, it is not necessary to engage the support bases 76, 78 with the rail 70, in which case the rail 70 is not necessary. .

As shown in FIGS. 5 and 6, the timing pulley 96
And 98 are rotatably supported by rotation sources 104 and 106 attached to supports 76 and 78, timing pulleys 108 and 110 attached to the output shafts of the rotation sources, and supports 76 and 78, respectively. A pair of tension pulleys

Instead of using 18, other transmission means such as sprockets and chains can be used.

As shown in FIGS. 2 and 5, each screw rod 72 is protected from dust by a pair of bamboo springs 120 and 122.
The bamboo spring 120 is a beam member of the moving base 40 so as to surround a portion of the screw rod 72 between the beam member 50 of the moving base 40 and the support base 78.
It is fixed to 50 and a support base 78. On the other hand, the bamboo shoot spring 122 is fixed to the support bases 76 and 78 so as to surround the screw rod 72 between the support bases 76 and 78. FIG. 1 does not show the bamboo shoot springs 120, 122 for the purpose of showing the threaded rod 72.

As shown in FIGS. 1, 4, and 6, each slider 80 of the support base 76 supports the transfer arm 124. Each transfer arm 124 is engaged with a pair of rails 126 attached to the front surface of the slider 80 so as to extend in parallel with the base member 46 of the moving base 40 so as to be slidable in the direction along the rails. It corresponds to the beam receiving unit 16 of the device 12 to be delivered. Both transfer arms 124 are laterally separated from each other and project forward from the corresponding sliders 80 so as to horizontally receive and support the beam 14.

As shown in FIG. 3, each transfer arm 124 has a recess 128, 130 that receives the axis of the beam 14. Recesses 128 and 130
Are used to deliver the beam 14 to and from the recesses 22 and 24 of the delivery target device 12, respectively. Recess 13
The depth dimension of 0 is greater than the depth dimension of the recess 128 and is also greater than the radial dimension of the shank 14b of the beam 14, preferably the diameter dimension of the shank 14b.

As shown in FIG. 4, the transfer arms 124 are connected by a rod 132 so that they cannot move relative to each other, and the distance between the outer surfaces of both transfer arms 124 is between the inner surfaces of the beam receiving portion 16. It is maintained to be slightly shorter than the distance. Both transfer arms 124 are arranged between both beam receiving portions 16 by moving the moving table 40 forward with respect to the carriage 28 at the delivery position.

Although the rod 132 is shown in FIG. 1 as being placed in front of the support base 76, it is actually placed below the support base 76 as shown in FIGS. 4 and 5. There is.

As shown in FIG. 6, the tip end surface of each transfer arm 124 is an outward tapered surface 124a, and the corresponding beam receiving portion is formed.
The end of 16 is an inwardly tapered surface 16a.

Therefore, when the carrier device 10 is moved to the delivery position, the transfer arm 124 moves with respect to the beam receiving portion 16 to the moving table 40.
When the transfer arm 124 is deviated in the movable direction with respect to, the movable table 40 is moved forward with respect to the carriage 28, so that the end surfaces 124a, 16a of the arm 124 and the beam receiving portion 16 first contact and then move. By further advancing the platform 40, the arms 124 are moved along the rails 126 until the outer surfaces of both arms 124 contact the inner surfaces of the corresponding beam receiving portions 16. As a result, the transfer arm 12 with respect to the beam receiving portion 16 is
The lateral displacement of 4 is automatically corrected.

Only one of the transfer arm 124 and the end surfaces 124a, 16a of the beam receiving portion 16 may be a tapered surface.

A position adjusting mechanism 134 for adjusting the position of the transfer arm 124 with respect to the carriage 28 is also arranged on the support base 76.

As shown in FIG. 8, the position adjusting mechanism 134 includes a pair of L-shaped brackets 136 attached to the connecting body 84 of the support base 76 at intervals in the moving direction (lateral direction) of the transfer arm 124.
And a pair of sliders 138 corresponding to the brackets and movably supported in the respective brackets so as to move in a direction away from each other, and a pair of sliders 138 corresponding to the sliders and moving the corresponding sliders toward a counterpart slider. Spring 140
And a transmission body 142 for mutually transmitting the movement of the slider 138 and the rod 132.

Each slider 138 has a rod portion 138a and a spring seat 138b fixed to the tip portion of the rod portion. Both sliders 138
Are slidably supported by the corresponding brackets 136 by the rod portions 138a so that the spring seats 138b face each other. A spring seat 144, through which the rod part 138a slidably passes, is arranged at a portion of each rod part 138a between the spring seat 138b and the bracket 136. Spring seat 138b of each rod 138a
A washer 146 and a nut 148 that prevent the slider 138 from coming off the bracket 136 are provided at the end opposite to
Are arranged.

Each spring 140 is a compression coil spring in the illustrated example, and is arranged between the spring seats 138b and 144. Transmission 142
Are fixed to the rod 132, and project from the portion fixed to the rod 132 into the space between the sliders 138.

When the force for displacing the rod 132 with respect to the moving body does not act on the rod 132 in the position adjusting mechanism 134, the slider 138 is maintained at a position where the force of the spring 140 is balanced. As a result, the rod 132 and thus the transfer arm 124 are
Is maintained in place.

However, when a force that displaces the rod 132 with respect to the support base 76 acts on the rod 132, the slider 138 arranged on the side of the moving direction of the rod 132 causes the transmission member 142 to cause the corresponding spring 14 to move.
The spring 140 is displaced against the force of 0, whereby a force corresponding to the displacement amount of the rod 132 is accumulated in the spring 140.

When the force that displaces the rod 132 with respect to the support base 76 is released, the slider 138 disposed on the side of the rod 132 in the moving direction is released.
Are pushed back by the force stored in the corresponding spring 140. As a result, the transmission body 142 is pushed, so that the rod 132
Is moved to its original position.

Each spring 140 may be arranged in a compressed state so as to always press the corresponding slider 138, or the corresponding slider 138.
Corresponding slider 138 unless compressed by the displacement of
You may arrange | position in an extended state so that a pressing force may not be applied to. At this time, the spring pressure may be adjusted by the nut 148 so that the spring seat 138b presses the transmission body 142, or may be adjusted so as to have a contact or a gap to the extent that the pressing force does not act. .

As shown in FIGS. 3, 4, and 9, a frame assembly 150 is supported by each slider 82 of the support base 78. Each frame assembly 150 is arranged on a table 152 fixed to the slider 82, a pair of rails 154 fixed on the table so as to extend in the lateral direction, and movably arranged on the table 152 along the rails 154. And a frame 156. Both frames 156
Are connected by a connecting rod 158 so that both move integrally.

The connecting rod 158 has a rack portion 1 formed at the center thereof.
A gear 162 that has 60 and meshes with the rack portion 160.
By rotating (see FIG. 1), it is moved laterally. As shown in FIGS. 4 and 5, the rotation mechanism 164 for rotating the gear 162 is attached to the support base 78.

As shown in FIG. 9, each frame assembly 150 also has a first link piece 166 rotatably arranged about an axis extending in the vertical direction. The first link piece 166 is
A bearing 168 arranged at the rear end portion thereof and a first shaft 170 fixed to the frame 156 so as to extend in the vertical direction are supported so as to extend forward from the frame 156.

At the rear end of each first link piece 166 is a warm wheel 1
72 is fixed coaxially with the first shaft 170. Each worm wheel 172 has a common rod 174 fixed worm
Meshed with 176. The rod 174 is rotatably supported by the frame 156, and is normally and reversely rotated by a rotating mechanism 178 which is supported by one frame 156 and is shown in FIGS. 3 and 4. The two worms 176 have mutually opposite threads. Therefore, the rod 174 is rotated by the rotation mechanism 178.
When rotated by, the first link pieces 166 are angularly rotated in directions opposite to each other. The rod is shown in FIG.
174 and rotation mechanism 178 are not shown.

Each of the first link pieces 166 supports the second link piece 182 at the tip thereof via a second shaft 180 extending in the vertical direction. The second shaft 180 is rotatably supported by the first link piece 166 by the bearing 184, but the second link piece 1
It is fixed at 82. First and second shafts 166 and 182
The sprockets 188 and 190, which are connected by a chain 186, are fixed to each of them. Therefore, each second link piece 182 is angularly rotated in the opposite direction to the first link piece 166 with the rotation of the corresponding first link piece 166.

The number of teeth on the sprockets 188 and 190 is selected to be 2: 1. Therefore, each second link piece 182 causes the first link piece 1 to rotate as the corresponding first link piece 166 rotates.
It is rotated twice as much as 66. As a result, the first
The link mechanism including the second link 166 and 182 is expanded and contracted in combination with the rotation of the rotation mechanism 178 rotating the first and second links 166 and 182 in mutually opposite directions.

As shown in FIG. 1, the arm 19 for supporting the dropper device, the heddle frame and the reed is provided at the tip of each second link piece 182.
Two are connected. Each arm 192 has a chuck 194 that holds the dropper device and a chuck 196 that holds the heald frame.
And are hung. The chucks 194 are connected to each other by a rod 198.

The carrier device 10 further includes a tension adjusting mechanism 200 that applies a tension to the warp threads of the beam 14 supported by the transfer arm 124.

As shown in FIGS. 9 to 11, the tension adjusting mechanism 200 is angularly rotatable about an axis extending in a direction (transverse direction) parallel to the axis of the beam 14 supported by the transfer arm 124. A support arm 202 supported by one transfer arm 124, a case 204 supported by the support arm, a rotation source 206 fixed to the case, and an axis parallel to the rotation axis of the support arm 202. Shaft 2 rotatably supported by case 204
08 and a roller 210 rotatably supported on the shaft
And a rotor 212 rotatably supported on the shaft 208,
A circular stator 214 fixed to the transfer arm 124 so as to center on the rotation center of the support arm 202, and a rotor 212 and a coupling body 216 hung on the stator 214.

The support arm 202 and the stator 214 are, as shown in FIG. 11,
Pins 218 and nuts 220 place them on opposite sides of the transfer arm 124. The shaft 208 is
As shown in FIG. 12, the case 204 penetrates in a direction parallel to the rotation center of the support arm 202, and is rotated by a rotation source 206 via bevel gears 222, 224.

The roller 210 is arranged at one end of the shaft 208 so as to come into contact with the outer peripheral surface of the flange 14a of the beam 14, and is connected to the shaft 208 via a friction clutch 226. The rotor 212 is arranged at the other end of the shaft 208, and also through another friction clutch 228, the shaft 208.
Are linked to.

In the illustrated example, the rotor 212 and the stator 214 are sprockets and the connecting body 216 is a chain, but other means such as a timing pulley and a timing belt may be used instead.

The rotation source 206 of the tension adjusting mechanism 200 is rotated in one direction while the transfer arm 124 receives the beam 14 on which the warp is wound and during the delivery of the beam 14 on which the warp is wound. As a result, the counterclockwise rotational force in FIG. 10 acts on the rotor 212 via the friction clutch 228, so that the engagement of the rotor 212 and the chain 216 causes the clockwise rotational force in FIG. Acts on the support arm 202.

The tension adjustment mechanism 200 is maintained in the position shown by the solid line in FIG. 10 when the beam 14 is received in the recess 128, and is shown by the chain double-dashed line in the figure when the beam 14 is received in the recess 130. Maintained in position. Also, when the roller 210 is not in contact with the beam 14, the support arm 202 is angularly rotated until the roller 210 contacts the flange 14a of the beam 14. On the other hand, when the roller 210 comes into contact with the flange 14a of the beam 14, the friction clutch 228 slips, so that the support arm 2
02 is not rotated any more.

When the rotation source 206 of the tension adjusting mechanism 200 is rotated, the tenth
In the drawing, the rotational force in the counterclockwise direction acts on the roller 210. Therefore, in FIG. For this reason, if there is slack in the warp that extends from the beam 14,
To be wound up. When the tension of the warp extending from the beam 14 exceeds the value determined by the friction clutch 226, the friction clutch 226 slips, so that the roller 210 does not rotate.

When a force for pulling out the warp from the beam 14, that is, an excessive tension acts on the front end portion of the warp, the beam 14 is rotated in the direction in which the warp is fed, so that the warp is pulled out from the beam 14. At this time, the roller 210 is rotated by the rotation of the beam 14 against the force of the friction clutch in the direction opposite to the rotation direction of the rotation source 206.

When passing the beam 14 around which the warp is wound, the dropper device through which the warp is passed, the heddle frame, and the reed to the delivery target device 12, the carrying device 10 receives the shaft portion 14b of the beam 14 in the recess 128 and the dropper device. Also, the heddle frame is moved to the delivery position while being held by the chucks 194 and 196.

At the time of delivery, the reed is detachably locked to the heddle frame. Further, the front end portion of the warp thread extending from the beam 14 is locked to the reed. Therefore, there is no possibility that the warp will come off from the dropper device, the heddle frame, and the reed.

While the carrying device 10 is moved to the delivery position, the moving table 40 and the arm 192 are retracted to the predetermined positions, and the supporting table 76,
78 is lowered to a predetermined height position, and the transfer arm 124
Is maintained at a predetermined position by the position adjusting mechanism 134. In addition, the warp wound on the beam 14 is a dropper device,
It is passed through a through member such as a heddle frame and a reed, and is maintained at a predetermined tension by a tension adjusting mechanism 200.

When the carrier 10 is moved to the delivery position, first, the support base
The rotation sources 104 and 106 for 76 and 78 are normally rotated, and the support bases 76 and 78 are raised to a predetermined height position. As a result, the beam 14 is raised until the height position of the shaft portion 14b thereof is slightly higher than that of the upper surface of the beam receiving portion 16, and the dropper device, the heddle frame and the reed are delivered at their lower end edges. It is raised until it is above the upper surface of the target device 12.

Next, in order to deliver the beam 14, the rotation source 58 for the moving table 40 is rotated forward, and the moving table 40 is moved forward by a predetermined distance. As a result, the transfer arm 124 is advanced to a position where the recess 128 coincides with the recess 22 of the beam receiving portion 16 in the front-rear direction.

When the transfer arm 124 is moving forward, the transfer arm 124 receives the beam receiving portion.
If it is slightly displaced from the 16 along the rail 126,
Since the transfer arm 124 is moved with respect to the support base 76 by the cooperation of the end surface 124a of the transfer arm and the end surface 16a of the beam receiving portion 16, the transfer arm 124 in the direction along the rail 126 is moved.
The relative displacement between the beam receiving portion 16 and the beam receiving portion 16 is automatically corrected. Further, when the transfer arm 124 is moved with respect to the support base 76, the transmission body 142 of the position adjustment mechanism 134 is moved, so that a force corresponding to the amount of movement of the transfer arm 124 is generated by the position adjustment mechanism 134. Accumulated in the spring 140 of the spring.

Then, the rotation source 104 for the support base 76 is reversed to support the support base 7
6 is lowered into place. As a result, the transfer arm 124
Is lowered to a position below the height of the beam receiving portion 16, and the beam 14 is passed from the recess 128 of the transfer arm 124 to the recess 22 of the beam receiving portion 16.

Then, the rotation source 58 for the moving table 40 is reversed to move the moving table 40.
Is retracted a predetermined distance. As a result, the transfer arm 124 is
The recess 130 is moved to a position corresponding to the recess 22 of the beam receiving portion 16 in the front-rear direction.

Then, the rotation source 104 for the support base 76 is rotated in the normal direction again to raise the support base 76 to a predetermined position. As a result, the transfer arm 124 is lifted to a position where its upper surface is slightly above the height position of the shaft portion 14b of the beam 14, and the shaft portion 14b of the beam 14 is received in the recess 130.

Next, the rotation source 58 for the moving table 40 is further rotated in the normal direction, and the moving table 40 is further advanced by a predetermined distance. As a result, the transfer arm 124 has the recess 130 in the front-back direction.
Is moved to a position corresponding to the recess 24 of the
b is received in the recess 24. When the transfer arm 124 is advanced, the shaft portion 14b of the beam 14 is moved on the upper surface of the beam receiving portion 16 while being received in the recess 130. As a result, there is no possibility that a large rotation moment will act on the transfer arm 124.

After that, the rotation source 104 for the support base 76 is reversed, and then the rotation source 58 for the movable base 40 is reversed, whereby the support base 76 is lowered to a predetermined position, and the movable base 40 is retracted to the predetermined position. To be done. This causes beam 14 to be recessed 128-130, recess 22,
After passing to the recess 24, the delivery of the beam 14 is completed.

During the delivery of the beam 14, the rotation source 206 of the tension adjusting mechanism 200 is rotated. Therefore, the roller 210 of the tension adjusting mechanism 200 is
Even when the transfer arm 124 is moved in the vertical direction and the front-back direction, the angular contact force acting on the support arm 202 makes contact with the flange 14a of the beam 14. As a result, the roller 210 exerts a rotating force on the beam 14 in the winding direction of the warp, and the tension of the warp is always maintained at a value determined by the friction clutch 226.

When the transfer arm 124 is separated from the beam receiving portion 16, the transfer arm 124 is moved laterally along the rail 126 with respect to the support base 76 by the force accumulated in the spring 140 of the position adjusting mechanism 134. Then, it is automatically returned to a predetermined position in the lateral direction.

At the same time as the delivery of the beam 14 or after the delivery of the beam 14, for the delivery of the dropper device, the heddle frame and the reed,
With the dropper device, the heddle frame, and the reed being moved above the delivery target device 12 by the operation of the rotation source 106,
The rotating mechanism 178 is normally rotated. This allows the link pieces 166,1
The link mechanism consisting of 82 is extended so that the dropper device and the heddle frame are respectively arranged in the vertical direction.
It is moved to a position facing 18 and the heald frame receiving portion 19.
In this position, the dropper device and the heddle frame are lowered to a predetermined position by the rotation source 106 being normally rotated, and then lowered to a predetermined position by the rotation source 106 being normally rotated, respectively. , Chucked by the operator
It is removed from 194 and 196 and transferred to predetermined receiving portions 18 and 19. The reed is removed from the heddle frame during transfer of the heddle frame and is transferred to the reed receiving part 20.

Then, the rotating mechanism 178 is reversed to contract the link mechanism. After that, when the transfer of the beam 14 is completed and the movable table 40 is retracted to the predetermined position, the rotation source 106 for the support table 78 is reversed and the support table 78 is returned to the predetermined height position. .

When the beam 14 around which the warp is wound, the dropper device, the heddle frame, and the reed are received from the delivery target device 12, the carrying device 10 is operated in the opposite manner.
