(Prior Art) As one of delivery devices for a warp beam for work in progress, a transport mechanism equipped with a carriage movable to a delivery position of the warp beam, and a beam mechanism so that an axis line of the beam is horizontal. To receive the shaft rotatably around its axis,
A delivery mechanism including a pair of transfer arms arranged in parallel at a distance in the horizontal direction, a drive mechanism for moving the delivery mechanism with respect to the carriage to deliver the beam, and a warp extending from the beam were passed. There is a device including a support mechanism for supporting a reciprocating member such as a reed, a cord and a dropper device (for example, JP-A-62-184149 and JP-A-63-4294).
No. 4, gazette of the Shokai 63-149982 gazette).

Each transfer arm corresponds to a beam receiving portion provided on the loom or the workbench preparation workbench. At the time of delivery, the known delivery device is moved to the delivery position for the loom or the machine work preparation workbench. Each delivery mechanism
At the delivery position, the warp beam is delivered by moving in the front-rear direction and the up-down direction.

However, in the known delivery device, since the delivery mechanism is only moved in the front-back direction and the up-down direction during delivery, the relative orientation between the delivery mechanism and the beam receiving portion in the direction intersecting the front-rear direction and the up-down direction, that is, the lateral direction. If the physical positional relationship is incorrect, the beam cannot be delivered, and therefore the delivery device must be accurately stopped at a predetermined position.

In order to solve the above-mentioned problem, the delivery mechanism is arranged so as to be movable in a lateral direction different from the moving direction of the drive mechanism with respect to the trolley, and the delivery mechanism is transported so as to match the positional relationship between the transportation mechanism and the delivery mechanism in the lateral direction during delivery. When the function is moved with respect to the function, it is necessary to manually return the delivery mechanism to the original position after the delivery is completed.

(Problem to be Solved) According to the present invention, even if the delivery means is moved in the first direction with respect to the transportation means so as to match the positional relationship between the delivery means and the delivery means, the delivery means is separated from the delivery means. Therefore, the delivery means automatically returns to the original position.

(Solution Means, Actions and Effects) The delivery device of the present invention is provided with a beam for a loom or a preparation pedestal having a pair of receiving means arranged at intervals in the horizontal direction to horizontally receive the warp beam. A delivery device that is movable to a delivery position of the beam, and a pair of arms spaced apart in a horizontal first direction to deliver the beam, A delivery means movably arranged at a predetermined position in the first direction of the transportation means, and the delivery means with respect to the transportation means so as to allow the delivery means to deliver the beam. Drive means for moving in the horizontal second direction and up and down third direction toward the receiving means, which intersects the direction, and a force for displacing the delivering means with respect to the receiving means in the first direction. Position returning means for maintaining the delivery means at a predetermined position in the first direction by the force of the pair of spring means when not acting on the delivery means.

The delivery means is moved in the second and third directions by the drive means at the delivery position. At this time, if the delivery means is displaced with respect to the reception means in the first direction different from the moving direction of the drive means, the delivery means comes into contact with the reception means when the delivery means is moved toward the reception means. , I can't deliver the beam.

In such a case, the delivery means is moved in the first direction with respect to the transportation means against the spring force of the position maintaining means to move the first means.
It suffices to correct the relative positional relationship between the delivery means and the receiving means in the direction of, and move the delivery means toward the receiving means in this state. As a result, the delivery means is moved toward the receiving means such that one of the arm and the receiving means enters between the other.

When one of the arm and the receiving means is inserted between the other and the force for moving the delivering means in the first direction is released, the delivering means causes the arm to move by the spring force of the position maintaining means. Receives the force that is pressed against the side of the.
Thereby, the arm is engaged with the side surface of the receiving means.

When the delivery means is separated from the delivery means, the delivery means is returned to the predetermined position in the first direction by the spring force of the position maintaining means.

Therefore, according to the present invention, even when the delivery means is moved in the first direction with respect to the transportation means, the delivery means is automatically returned to the predetermined position by separating it from the reception means.

The position returning means includes a pair of sliders slidably supported by a bracket fixed to the carrying means, a transmission body disposed between the sliders and having an end fixed to the delivery means, and the pair of sliders. The spring means spring for urging the springs in the direction in which they are close to each other.

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 14a of the beam 14, preferably the diameter dimension of said shank.

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 surface 124a of each transfer arm 124 is shown.
Is an outwardly tapered surface, that is, an inclined surface, and the corresponding end surface 16a of the beam receiving portion 16 is an inwardly tapered surface, that is, an inclined surface.

Therefore, when the delivery 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 4
When the transfer arm 124 is displaced in the movable direction with respect to 0, the movable table 40 is moved forward with respect to the carriage 28, so that the end surfaces 124a and 16a of the arm 124 and the beam receiving portion 16 first contact with each other, and By further moving the moving base 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.

Each spring 140 is a compression coil spring in the illustrated example,
Further, it is arranged between the spring seats 138b and 144. Transmission 14
Reference numeral 2 is fixed to the rod 132, and projects 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
Maintained in place with respect to 76.

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 a corresponding spring.
The spring 140 is displaced against the force of 140, whereby a force corresponding to the amount of displacement of the rod 132 is accumulated in the spring 140.

When the force for displacing the rod 132 with respect to the support base 76 is released, the slider 1 placed on the side of the rod 132 in the moving direction is moved.
38 is 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 13
Corresponding slider 138 unless compressed by 8 displacements
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 support base 78
A frame assembly 150 is supported on each slider 82. 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 1
56 is a connecting rod 158 so that both move integrally.
Are connected by.

The connecting rod 158 has a rack portion 160 formed in the center thereof, and a gear that meshes with the rack portion 160.
When 162 (see FIG. 1) is rotated, it is moved laterally. As shown in FIGS. 4 and 5, the gear 16
A rotating mechanism 164 for rotating the 2 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, a worm wheel 172 is fixed coaxially with the first shaft 170. Each worm wheel 172 is meshed with a worm 176 fixed to a common rod 174. Rod 174 is frame 156
It is rotatably supported by one frame 15
The rotation mechanism 178 shown in FIG. 3 and FIG. The two worms 176 have mutually opposite threads. Therefore, the rod 174 is rotated by the rotation mechanism 1
When rotated by 78, the first link pieces 166 are angularly rotated in opposite directions. The rod 174 and the rotating mechanism 178 are not shown in FIG.

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 a bearing 184, but is fixed to the second link piece 182. First and second axes 166 and
Sprockets 188 and 190 connected by a chain 186 are fixed to 182, respectively. Therefore, each second
The link piece 182 is angularly rotated in the opposite direction of 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 is rotated by twice the rotation angle of the first link piece 166 with the rotation of the corresponding first link piece 166. As a result,
The link mechanism composed of the first and second links 166 and 182 is expanded and contracted as the first and second links 166 and 182 are rotated in opposite directions by the rotation of the rotation mechanism 178.

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

When passing the beam 14 around which the warp is wound and the dropper device, the heddle frame and the reed through which the warp is passed to the delivery target device 12, the delivery device 10 transfers the shaft portion 14a of the beam 14 to the transfer arm 1
The dropper device and the heald frame are received by the recesses 128 of 24, and are moved to the delivery position shown in FIG. 6 while being held by the chucks 194 and 196, respectively.

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 delivery device 10 is moved to the delivery position, the moving table 40
The arm 192 is retracted to a predetermined position, the support bases 76 and 78 are lowered to a predetermined height position, and the transfer arm 124 is maintained at the predetermined position by the position adjusting mechanism 134.

When the delivery device 10 is moved to the delivery position, first, the rotation sources 104 and 106 for the support bases 76 and 78 are normally rotated,
The supports 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 14a thereof is slightly higher than that of the upper surface of the beam receiving portion 16, and the lower end edges of the dropper device, the heddle frame and the reed are delivered. 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 moved forward, if the transfer arm 124 is slightly deviated from the beam receiving portion 16 in the direction along the rail 126, the transfer arm 124 is moved toward the end surface 124a of the transfer arm and the beam receiving portion 16. Since it is moved with respect to the support base 76 in cooperation with the end face 16a, the relative displacement between the transfer arm 124 and the beam receiving portion 16 in the direction along the rail 126 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.

The rotation source 104 for the support 76 is then reversed and the support 76 is lowered into position. As a result, the transfer arm
The beam 124 is lowered to a position below the height position 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 movable table 40 is reversed to move the movable table 40.
40 is retracted a predetermined distance. As a result, the transfer arm 124
Is the recess 130 of the beam receiving portion 16 in the front-back direction.
Moved to a position that matches 2.

Then, the rotation source 104 for the support base 76 is rotated forward again,
The support base 76 is raised 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 14a of the beam 14, and the shaft portion 14a of the beam 14 is
Is received in the recess 130.

Then, the rotation source 58 for the moving table 40 is further rotated forward,
The moving table 40 is further advanced by a predetermined distance. As a result, the transfer arm 124 has the recess 130 in the beam receiving portion in the front-back direction.
Moved to a position that matches 16 recesses 24, beam 14 shaft
14a is received in the recess 24. When the transfer arm 124 is advanced, the shaft portion 14a of the beam 14 is received in the recess 130,
The upper surface of the beam receiving portion 16 is moved. 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. As a result, the beam 14 is passed from the recess 128 to the recess 22, the recess 130, and the recess 24, and the delivery of the beam 14 is completed.

When the transfer arm 124 is separated from the beam receiving portion 16,
The transfer arm 124 is laterally moved 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, and is automatically returned to a predetermined position in the lateral direction. .

Simultaneously with or after the delivery of the beam 14, the dropper device, the heddle frame, and the reed are moved above the delivery target device 12 by the operation of the rotation source 106 for the delivery of the dropper device, the heddle frame, and the reed. In this state, the rotation mechanism 178 is rotated normally. This makes the link piece 1
The link mechanism composed of 66 and 182 is extended, and the dropper device and the heddle frame are moved to positions facing the dropper receiving portion 18 and the heddle frame receiving portion 19 in the vertical direction, respectively. In this position, the dropper device and the heald frame are
After the rotation source 106 is normally rotated and lowered to a predetermined position, the rotation source 106 is detached from the chucks 194 and 196 by an operator and transferred to predetermined receiving portions 18 and 19, respectively. 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, the delivery of the beam 14 is completed, and the support base 78 is moved in a state where the movable base 40 is retracted to a predetermined position.
The rotation source 106 for rotation is reversed and the support base 78 is returned to the predetermined height position.

When the beam 14 on which the warp is wound and the dropper device, the heddle frame, and the reed through which the warp is passed from the device 12 to be delivered, the delivery device 10 is operated in the opposite manner. Also,
When the empty beam 14 with no warp thread and the dropper device, the heddle frame and the reed with no warp thread passed are operated in the same manner as described above.
