Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt member for selecting a carriage supporting a roll, transferring it to an unwinding station, and unwinding and supplying the belt member from the roll. Related to a supply device.

2. Description of the Related Art Generally, rubber supplied on the way to be transferred from a kneader to another kneader and rubber supplied with a cord used for tire molding are:
After being formed into a belt shape, it is wound into a roll around the core,
It is temporarily stored on a trolley. here,
Since there are many types of rubber constituting the belt-like member, the trucks are temporarily assembled at a stock station for the sake of organization, and the belt-like members are taken out together with the truck from this stock station as needed, or the used ones are used for this purpose. Return to stock station.

Conventionally, the transfer of the band-shaped member and the bogie from such a stock station to the unwinding mechanism and vice versa from the unwinding mechanism to the stock station is performed by a worker using a forklift after confirming the type of the band-shaped member. Also, at the start or end of unwinding of the belt-like member, the operator pulls out or rewinds the starting end of the belt-like member while rotating the roll.

However, in such a method, since each operation such as transfer, unwinding and rewinding is performed by an operator, many operators are required and the operation efficiency is reduced. In addition, when the transfer timing is incorrect and the belt-shaped member is transferred to the unwinding mechanism during the unwinding operation, the operator must wait immediately before the unwinding mechanism, which also reduces the work efficiency. Was.

In order to solve such problems, for example, Japanese Patent Application Laid-Open
No. -40368, a feeding device combining an automatic coil feeding device described in JP-A-58-110125 and a coiler described in JP-A-58-110125, that is, different types of strip-shaped members arranged at a plurality of stock stations, respectively. A plurality of trolleys each rotatably supporting the wound roll from below, and a plurality of trolleys which are provided apart from the stock station, can support a plurality of rolls, and reciprocate while supporting the rolls. A switching mechanism for switching between the unwinding station and the standby station, a unwinding mechanism for rotating a roll located at the unwinding station at the start of unwinding and unwinding the start end of the belt-shaped member from the roll, and a stock station. It can move while supporting the roll between the unwinding and standby stations,
It is also conceivable to use a supply device provided with a transport mechanism capable of identifying the type of the band-shaped member wound up on the roll and delivering the roll to and from each station.

Here, in such a supply device, the starting end of the belt-shaped member is unwound from the roll by pressing the rotating unwind roller against the outside of the roll.
Since the unwinding roller transmits the driving force by linear contact with the roll, slippage is likely to occur between the unwinding roller and the unwinding operation. There is a problem that if the material is soft, it may be cut off on the way. In addition, when the band-shaped member is unwound from the roll, no guide is provided, so that if the band-shaped member is a soft material such as band-shaped rubber, meandering may occur. is there.

SUMMARY OF THE INVENTION The present invention provides a feeding device for a band-shaped member that can be unwound and unwound without causing cutting and meandering even when the band-shaped member is soft such as band-shaped rubber. The purpose is to do.

Means for Solving the Problems Such an object is achieved by a plurality of trolleys respectively arranged at a plurality of stock stations and rotatably supporting rolls each having a different type of band-shaped member wound from below, and a stock station. A switching mechanism for switching between the unwinding station and the standby station by reciprocating while supporting the two or more trolleys and supporting the trolleys; The unwinding / unwinding mechanism which unwinds or unwinds the starting end of the belt-shaped member from the roll by rotating the roll at the start of unwinding or at the end of unwinding, and between the stock station and the unwinding / standby station. It can move while supporting the cart, and can identify the type of band-shaped member supported by the cart. And a transport mechanism capable of transferring the carriage to and from each station, wherein the unwinding / rewinding mechanism is disposed immediately below the roll and extends in the unwinding direction of the belt-shaped member. Conveyor and elevating means for elevating the belt conveyor, and at the start of unwinding or at the end of unwinding, the elevating means further raises the belt conveyor even after contact with the roll, and contacts along the lower part of the roll. This can be achieved by lifting the roll by a belt conveyor whose part is deformed in an arc shape, then rotating the roll by running the belt conveyor, and unwinding or rewinding the starting end of the belt-like member from the roll.

Operation Now, it is assumed that a trolley is arranged at each of the plurality of stock stations, and each of the trolleys supports a roll on which a different type of band-shaped member is wound from below.
At this time, a predetermined type of band-shaped member is unwound from the roll located at the unwinding station, while the standby station is empty. During such unwinding, the transport mechanism moves to the stock station, and subsequently identifies the strip of the type to be unrolled from among the plurality of strips, and rolls and rolls of the type from the stock station. Receive. Next, the transport mechanism moves to the standby station, and transfers the supporting rolls and carts to the empty standby station. Next, when the unwinding of the belt-shaped member is completed, the unwinding / rewinding mechanism is operated to unwind and rotate the roll in the station, and the starting end of the extra belt-shaped member unwound from the roll is rolled. Rewind. Such rewinding is performed by further raising the belt conveyer after the belt conveyer is brought into contact with the roll by the elevating means, and lifting the roll by the belt conveyer whose contact portion is deformed in an arc shape along the lower part of the roll. It is performed by rotating the roll by running the conveyor, but the belt conveyor whose contact part is deformed in an arc shape along the lower part of the roll, that is, the belt conveyor where the contact part is in surface contact with the roll on a wide surface Because we do rewind,
Slip does not occur between the two, and as a result, even if the band-shaped member is a soft material such as band-shaped rubber, it is possible to prevent the band-shaped member from being cut off during rewinding based on the above-described slip. be able to. Also, at the time of such rewinding, the belt conveyor conveys the belt-shaped member while supporting it from below, so that the belt-shaped member can be prevented from meandering. next,
The switching mechanism is moved forward or backward to switch the roll and the trolley located at the standby station to the unwinding station and the roll and the trolley located at the unwinding station to the standby station. Next, the transport mechanism moves to the standby station, and receives the unrolled roll and carriage from the standby station. At this time, the transport mechanism may identify the type of the belt member of the roll to be received. Note that the transport mechanism may receive a roll or the like from the unwinding station when the unwinding is completed, and then switch the roll position by the switching mechanism. Next, the roll of the unwinding station is rotated by the unwinding mechanism, and the start end of the belt-shaped member is unwound by a predetermined length. Also at this time, the cutting and meandering of the belt-shaped member are prevented as in the above-described rewinding. Thereafter, the belt-shaped members are unwound one after another by the apparatus in the next step. On the other hand, the transport mechanism moves to an empty stock station and transfers the received roll and cart to the empty station. In this way, the roll, the transport of the cart and the unwinding at the end, the unwinding at the end, the unwinding, and the like can be performed mechanically, at high speed, and accurately, so that the number of workers can be reduced. Labor saving can be achieved and productivity can be improved.

Next, the piston rod 113 of the cylinder 112 is protruded to release the locking claw 111, and the locking claw 111 is locked to the locking protrusion 115 of the carriage 2. Next, the motor 119 is operated to rotate the screw shaft 108 in a direction opposite to the above, and the moving table 110 is moved forward. As a result, the carriage 2 supporting the roll 5 is drawn into the transport mechanism 92 and transferred, but at this time, the carriage 2 moves on the rotating roller 107, so that the transfer is easily performed.

When the carriage 2 is transferred from the stock station S to the transport mechanism 92 in this manner, the moving motor 97 operates, and the transport mechanism 92 moves to the home station H immediately after the standby station T while supporting the carriage 2. . next,
The positioning means 141 is operated to engage the positioning means 14 with the positioning member 142 to position and fix the transport mechanism 92 at the position. Next, the motor 119 is operated to rotate the screw shaft 108, and the moving table 110 is advanced. As a result, the carriage 2 is pushed forward by the contact body 123 of the movable base 110, and is transferred from the transport mechanism 92 to the switching mechanism 11, more specifically, to the empty supporting means 15 on one side. At this time, the cart 2 is rotatable
And 17, so that the transfer is easy. The moving table 110 stops moving when the carriage 2 comes into contact with the stopper 18 of the switching mechanism 11. Next, the piston 112 is retracted, the locking claw 111 is closed, and the locking claw 111 is released from the locking protrusion 115 of the carriage 2.
Next, the moving base 110 is retracted to the initial position by the operation of the motor 119. At this time, the cylinder of the support means 15 on one side
19 operates, the piston rod 20 protrudes, and the pressing block
The lower part of the carriage 2 into which the carriage 21 is loaded is pressed against the rollers 17 to switch the carriage 2 to the carriage 13 and lock it. At this time, the barcode reader 23 reads the barcode of the cart 2 to determine whether or not the type of the belt-shaped member 7 carried in is correct.

Next, when the unwinding operation of the belt-shaped member 7 from the roll 5 located at the unwinding station M is completed, the operation of the upper and lower conveyors 79 and 78 stops, and the rotation of the roll 5 also stops. At this time, since the brake bar 81 is always in sliding contact with the roll 5, the roll 5 stops rotating quickly due to the frictional resistance between the brake bar 81 and the roll 5. At this time, since the belt-shaped member 7 is unwound from the roll 5 by a predetermined length, the unwinding start end must be rewound onto the roll 5. For this reason, first, the lifter 42 of the unwinding / rewinding mechanism 41 located immediately below the roll 5 is operated to raise the elevator 43. This allows the belt conveyor 56
Although the belt conveyor 56 rises, even after the conveyor belter 49 abuts against the roll 5, the contact portion of the conveyor belt 49 further deforms in an arc along the lower periphery of the roll 5 to make surface contact. At the same time, the operation is continued even after the support rollers 47 and 48 come into contact with the roll 5. As a result, the roll 5 is lifted while being supported by the belt conveyor 56 from below, and both ends in the axial direction of the core 6 are separated from the bottom wall of the insertion groove 4. Then, the rise of the roll 5 is controlled by a belt conveyor.
56 rises to the position indicated by the phantom line in FIG. 7, and stops when the detection arm 68 swings by the core 6 and is detected by the proximity switch 70. At this time, both ends in the axial direction of the core 6 are located near the center in the vertical direction of the insertion groove 4 and do not fall out of the insertion groove 4. Next, the drive motor 50 is operated to move the conveyor belt 49 in the direction of the arrow C. Thus, the roll 5 rotates and the start end of the belt-shaped member 7 is rewound on the roll 5. At this time, since the core 6 is still located in the insertion groove 4, even if a horizontal external force acts on the roll 5, the roll 5 does not fall off the belt conveyor 56. Further, since the roll 5 is supported at two points by two parallel support rollers 47 and 48 separated from each other, the roll 5 is also prevented from dropping from the belt conveyor 56. Further, as described above, rewinding is performed by the conveyor belt 49 whose contact portion is deformed in an arc shape along the lower portion of the roll 5, that is, the belt conveyor 56 whose contact portion is in surface contact with the outer periphery of the roll 5 on a wide surface. As a result, no slippage occurs between them, and as a result, even if the belt-like member 7 is a soft material such as a belt-like rubber, the belt-like member during the rewinding based on the above-mentioned slippage can be used. Cutting of the member 7 can be prevented. Further, at the time of such rewinding, the conveyor belt 49 conveys the belt-shaped member 7 while supporting it from below, so that the belt-shaped member 7 can be prevented from meandering.
When most of the belt-shaped member 7 is rewound on the roll 5, the belt-shaped member 7 does not block the optical path of the detection sensor 84, and the light from the light emitter 85 is received by the light receiver 86. As a result, a detection signal is sent from the detection sensor 84 to the control device. At this time, the control device operates the belt conveyor 56 for a predetermined time from this point to completely rewind the belt-shaped member 7 to the roll 5. Next, the lifter 42 is operated to move the lift
43 is lowered together with the belt conveyor 56. As a result, the roll 5 descends, and both ends in the axial direction of the core 6 abut against the bottom wall of the insertion groove 4, and the roll 5 is transferred from the belt conveyor 56 to the carriage 2 again and supported from below. During the operation as described above, an external force such as vibration is applied to the cart 2, but since the cart 2 is locked to the switching cart 13 by the lock means 22, it does not fall down. In the case where the belt-shaped member 7 is completely unwound from the roll 5 and the core 6 is empty, the rewinding operation is unnecessary.

Next, when the motor 27 operates and the pinion 35 rotates,
The switching mechanism 11 moves to the other end while being guided by the rail 12 by the rack 26 and the pinion 35, and the roll 5 to be used next is switched to the unwinding station M and the used roll 5 is switched to the standby station U. in this way,
During the unwinding of the belt-shaped member 7 from the roll 5, the roll 5 to be used next is supplied, and when the roll 5 needs to be switched, the switching mechanism 11 is reciprocated to switch between the rolls 5. As a result, the time for switching can be reduced, and the efficiency of the supply operation of the belt-shaped member 7 is improved.

Next, the lifter 42 at one end is operated, and the roll 5 to be used next is transported by the belt conveyor 56 to the carriage 2 in the same manner as described above.
Lift slightly from. Next, the drive belt 50 is operated by driving the drive motor 50 in the direction opposite to the arrow C direction, and the roll 5 is rotated to unwind the start end of the belt-shaped member 7. Also at this time, the cutting and meandering of the band-shaped member 7 are prevented as in the above-described rewinding. Then, when the belt-shaped member 7 is unwound by a predetermined length, the detection sensor 84 detects the start end of the belt-shaped member 7. Conveyor belt 49 for a predetermined time from this detection point
Is further run, and the belt-shaped member 7 is unwound. Next, the lifter 42 is actuated, the lift 43 is lowered, and the roll 5 is transferred from the belt conveyor 56 to the carriage 2. At this time,
The upper and lower conveyors 79 and 78 run in the directions of arrows A and B, respectively.
9, picked up by 80. If the band-shaped member 7 is cut off during unwinding, the detection sensor 84 detects this, but in this case, the above-described operation is performed again.

At this time, the transport mechanism 92 is moved to just after the standby station U by the operation of the moving motor 97, and
1. The positioning member 142 is positioned and fixed at the position. Next, the cylinder 19 operates to release the carriage 2 located at the standby position U from the lock. Next, the motor 119 operates to rotate the screw shaft 108, and the contact body 123 moves forward until it comes into contact with the carriage 2. Next, the cylinder 112 is operated to release the locking claw 111, and the locking claw 111 is
Is locked. Next, the motor 119 operates again, and the screw shaft 1
08 rotates in the opposite direction to that described above, and the moving table 110 moves backward.
As a result, the carriage 110 pulls the carriage 2 and the used roll 5 located at the standby station U into the transport mechanism 92, and switches the carriage 2 and the roll 5 from the switching mechanism 11 to the transport mechanism 92.
Transfer to Next, the moving motor 97 is operated, and the transport mechanism 92 is operated.
Moves toward the stock station S. At this time, since a signal regarding the empty stock station S is sent from the control device to the transport mechanism 92, the transport mechanism 92 moves to just after the empty stock station S and stops. Next, the motor 119 is operated to move the movable platform 110 forward, and the carriage 2 and the roll 5 are transferred from the transport mechanism 92 to the empty stock station S. Next, after the movable table 110 retreats, the transport mechanism 92 moves to the home station H and waits at the position until the next operation.

On the other hand, even when the band member 7 is completely unwound from the roll 5 and the core 6 is empty as described above,
92 receives the bogie 2 and the empty core 6 from the switching mechanism 11,
In this case, the transport mechanism 92 moves to the home station H instead of the stock station S, and transfers the empty core 6 to the collection mechanism 190. That is, when the transport mechanism 92 reaches the home station H and is fixed in position, the collection mechanism
The motor 165 of the 190 operates to rotate the pinion 164. As a result, the collection mechanism 190 moves the pinion 164 and the rack 161
While being guided by the guide rails 153 to the position just above the home station H. Next, the piston rod 173 of the cylinder 172 is protruded to raise and lower the frame 171,
At the same time as the 182 is lowered, the piston 187 of the cylinder 186 is retracted to open the gripping claws 182. When the claw 182 of the gripping claw 183 descends below both ends in the width direction of the core 6 as shown by the imaginary line in FIG. 11, the operation of the cylinder 172 is stopped and the piston rod 187 of the cylinder 186 is protruded. Then, the gripping claws 182 are closed. Thereby, the core 6
Are gripped by gripping claws 182. Next, the piston rod 173 of the cylinder 172 is retracted, the lifting frame 171, the gripping claws 182, and the core 6 are integrally raised to the position shown by the solid line in FIG. 11, and the core 6 is pulled out of the carriage 2. Next, the motor 165 is operated to move the collection mechanism 190 to the alignment mechanism.
After moving to just above 151, the piston rod 173 of the cylinder 172 is protruded to lower the lifting frame 171, the gripping claws 182, and the core 6 integrally. When both ends of the core 6 in the axial direction come into contact with the vicinity of the deepest portion of the triangular groove 207 of the alignment plate 203, the operation of the cylinder 172 is stopped, and the piston rod 187 of the cylinder 186 is retracted so that the gripping claw 182 is pulled. Open. As a result, the empty core 6 is transferred from the collection mechanism 190 to the alignment mechanism 151, and the transferred core 6 is detected by the proximity switch 208. Next, cylinders 172, 18
6 and the motor 165 are operated to return the collection mechanism 190 to the initial state, while the transport mechanism 92 returns only the cart 2 to the empty stock station S and then returns to the home station H. The collection of the core 6 is performed by the roll 5
Is carried out every time the band-shaped member 7 is completely unwound to form an empty core 6, and the empty core 6 is sequentially aligned from the rear side while being aligned on the alignment plate 203 so as to engage with the triangular groove 207. Is placed. On the other hand, a storage cart 189 is carried in immediately below these alignment plates 203 by an operator.
Then, as described above, the triangular groove 2 is placed on the alignment plate 203.
When the same number of cores 6 as the number of 07 are placed, the lifter
The storage cart 189 is raised by the operation of 209, and the lifting is continued even after the base 216 contacts the core 6 supported by the alignment plate 203. As a result, the core 6 is lifted by the base 216, and the proximity switch 208 detects lifting of the core 6 from the alignment plate 203. Next, the cylinder 202 and the piston rod 204 are simultaneously retracted to separate the alignment plates 203 from each other, and the alignment plates 203 are retracted from the core 6. As a result, the core 6 is transferred from the alignment mechanism 151 to the storage cart 189 while being aligned. Next, the lifter 209 is operated, and the elevator 210 and the storage trolley 189 are lowered. When the same number of cores 6 as the number of triangular grooves 207 are placed on the alignment plate 203 again, the storage cart 189 is raised again by the lifter 209, and then the alignment plate 203 is retracted. Is already aligned, storage cart 18
9 is transferred onto the core 6 transferred. As a result,
The core 6 accommodated in the storage cart 189 has four stages.
Rather than a staggered arrangement that sequentially changes from three to three, the number of each stage is four in parallel, and the same number of cores 6 can be stored in the same volume. When the cores 6 are successively stacked on the storage cart 189 and become full, the detection sensor 226 detects that the core 6 is full. As a result, the worker can use the empty storage cart 189 and the full storage cart 1
Exchange with 89. And the operation as described above is repeated,
The belt members 7 of the desired type are supplied one after another to the kneader in the next step.

In the embodiment described above, the stock stations S are arranged in a straight line, but in the present invention, they may be arranged in a curved line. Also,
In the above-described embodiment, the two carts 2 are connected to the switching mechanism 11.
However, in the present invention, three or more carts may be supported. Further, in the present invention, when the unwinding of the belt-shaped member 7 is completed, the transport mechanism 92 receives the roll 5 from the switching mechanism 11 of the unwinding station M, and then switches the roll position by the switching mechanism 11. Is also good.

Effect of the Invention As described above, according to the present invention, even when the belt-shaped member is a soft material such as a rubber sheet, it can be unwound and unwound without causing cutting and meandering.
