Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a long member unwinding trolley capable of unwinding a long member previously stored as a roll.

[0002]

2. Description of the Related Art Generally, in a tire manufacturing process, a tire constituent member such as a belt member is formed by winding one long member into a roll, and the roll is stored in a truck. Further, a sheet for preventing adhesion, which is called a liner, is inserted between the members so that the rubbers do not adhere to each other. The trolley | bogie shown in FIG. 3 is an example of the conventionally used unwinding trolley | bogie. This trolley 30 is provided with a shaft 32 and a bearing 33 for winding a tire constituent member, which is a long member, as a scroll 31 on the lower side, and a scroll 31 on the upper side.
A liner take-up shaft 35 for taking up the liner 34 and a bearing 36 for taking up the liner 34 when unwinding the tire constituent member are provided, and wheels 37 are provided on the lower surface. The dolly 3 of FIG.
No. 0 is a double type that allows you to wind and unwind two scrolls at the same time.

This trolley 30 is moved and installed at a predetermined place of a tire molding machine, and the tire constituent members are unwound from a scroll 31 to an unwinding device to supply the tire constituent members to a servicer of the tire molding machine, while The liner 34, which is unwound simultaneously with the constituent members, is wound around the liner winding shaft 35.

[0004]

However, in the trolley 30 described above, the scroll 31 is stored in the storage location together with the trolley 30, and the trolley 30 is moved between the storage location and the unwinding work location. When changing the type and size of the member, the scroll 31 is replaced with the trolley 30, so that the following problems occur. (1) Compared to a scroll, the trolley occupies a large storage area, resulting in poor storage space efficiency. (2) It is necessary to secure a space for the truck to pass through the passage between the storage place and the unwinding work place, and it is difficult to effectively use the space in the factory. (3) It is necessary to prepare as many trolleys as the number of scrolls to be stored (in the case of the double type, the number of trolleys is half, but there is a problem that the trolleys are large and take up a lot of space), and the cost of manufacturing and maintenance high. (4) It takes time to replace the dolly.

The present invention has been made in view of the above circumstances, and it is possible to improve the storage efficiency of scrolls, easily move between the storage place and the unwinding work place, and effectively use the space in the factory. It is possible to reduce the number of trolleys, reduce the total cost of manufacturing and maintaining the trolleys, and to provide an unwinding trolley of a long member that can easily perform the work of exchanging a scroll. .

[0006]

SUMMARY OF THE INVENTION In view of the above, an unwinding carriage for a long member according to the present invention comprises a reel in which the long member is wound with a liner and a flange diameter is larger than a maximum winding diameter. A frame body to be housed, a bearing member that rotatably and detachably supports the reel housed in the frame body from both sides, and a reel member for lifting or lowering the reel from the floor surface via the bearing member. The lifting and lowering device, a liner winding shaft for winding a liner wound together with the long member from the reel, and a brake mechanism for applying a braking force to the rotating reel are adopted.

It is desirable to arrange a liner peeling roll, a reversing roll, and a returning roll in order from the reel side between the reel and the liner winding shaft.

[0008]

According to the present invention, the reel unit can be stored in the storage place. Since the reel brim diameter is larger than the maximum winding diameter of the long member, even if the reel brim is grounded on the floor surface, the scroll is not grounded on the floor surface. Therefore, as compared with the conventional method in which the trolley is stored in the storage location, only the reel itself is stored, so that the storage efficiency of the roll is improved. When moving from the storage location to the unwinding work location, the reel to be used can be rolled and moved easily. The moving space can be reduced as compared with the conventional method of moving the entire trolley, and the space in the factory can be effectively used. Moreover, the reel is smaller than the dolly, has a small turning ability, and is easy to handle.
In addition, it is not necessary to arrange the reel setting trucks for each reel, and it is sufficient to prepare one truck at the unwinding work place.

Further, as described in claim 2, a liner stripping roll, a reversing roll, and a returning roll are arranged in order from the reel side between the reel set on the frame and the liner winding shaft, whereby a long length is obtained. It becomes possible to achieve stable unwinding of the member and reliable winding of the liner at the same time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. In these drawings, reference numeral 1 denotes an unwinding carriage according to the present invention, reference numeral 2 denotes a reel, and reference numeral 10 denotes a frame body. The reel 2 and the frame body 10 basically constitute the unwinding carriage 1.

The reel 2 has a cylindrical core member (not visible in FIG. 1) capable of winding the long member B together with the liner R as a scroll 3, and a disk-like member fixed to both sides of the core member. It is composed of the tsuba 4 and. The collar 4 has a diameter larger than the maximum winding diameter of the scroll 3. A shaft hole (not visible in FIG. 1) is formed in the shaft center of each of the collars 4 so that a shaft 5 supported by a bearing arm 14 described later can be removably mounted from both sides. At the rear end of the shaft 5, a disc 8 forming a brake mechanism 6 for applying a braking force to the rotating reel 2 is fixed together with the grip member 7.

The frame body 10 has a space capable of accommodating the entire reel 2, and a lower frame 11 in which the frames are located on both sides of the collar 4 of the reel 2 in a state of accommodating the reel 2, and the lower frame 1
1, a vertical frame 12 in which the frame rises vertically, and an upper frame 13 in which the frame extends forward from the upper end of the vertical frame 12,
The front surface of the lower frame 11 is formed by rolling the reel 2 from the front surface side.
Notched so that it can be accommodated in 0.

Both vertical frames 12a located behind the vertical frames 12 (only one vertical frame 12a is visible in FIG. 1)
A base end of a pair of bearing arms (bearing members) 14 is vertically rotatably supported on the inner surface of the. The pair of bearing arms 14 are located on both sides of the collar 4 of the reel 2, and a through hole is formed in the plate thickness direction at its free end.
The reel 2 is detachably supported on the bearing arm 14 by inserting the shaft 5 through the shaft hole. The gripping member 7 for gripping the disk 8 integral with the shaft 5 is attached to the free end side of the bearing arm 14.

The tip of a rod 16 of a cylinder (elevating device) 15 is fixed to the upper surface of the bearing arm 14. Therefore, the rod 16 of the cylinder 15 can be extended or contracted to swing the bearing arm 14 in the vertical direction with the base end portion of the bearing arm 14 as the rotation axis. The cylinder 15 is fixed to the lower surface of the upper frame 13 and is suspended.

A bearing 17 is fixed to the upper surface of the upper frame 13. A driven roll 18 is rotatably supported by the bearing 17 in a cantilever state. Reference numeral 19 is a drive roll that comes into contact with the driven roll 18 and applies a rotational drive force.
The drive roll 19 is a part of the existing unwinding device.
In the figure, a feeder roll 20, which is a part of the unwinding device, is located diagonally rearward of the cart 1. A transmission belt 23 is wound around the pulley 21 of the feeder roll 20 and the pulley 22 of the drive roll 19. The rotational driving force of the drive roll 19 is also transmitted to the feeder roll 20 via the transmission belt 23.

Below the feeder roll 20, a long member B is provided.
The liner take-up shaft 24 is located at a position where it does not interfere with. A transmission belt (not shown) is also wound between the liner take-up shaft 24 and the driven roll 18 via the clutch mechanism 24a, and the rotational driving force of the driving roller 19 is taken up via the driven roller 18. It is adapted to transmit to the shaft 24. Therefore, the rotation of the liner winding shaft 24 is synchronized with the rotation of the feeder roll 20.

A tension roll 25 is located between the feeder roll 20 and the reel 2 accommodated in the carriage 1. Between the tension roll 25 and the feeder roll 20, a total of three rolls including a peeling roll 26, a reversing roll 27, and a return roller 28 of the liner R are positioned from the tension roll 25 side. The liner take-up shaft 24, the tension roll 25, the three peeling rolls 26, the reversing roll 27, and the return roll 28 are each supported by a part of the upper frame portion 13 of the carriage in a cantilevered state. The tension roll 25 and the three peeling rolls 2
6, the reverse roll 27, and the return roll 28 are free rolls.

Next, a procedure for unwinding the long member B from the unwinding carriage 1 configured as described above to the unwinding device upstream will be described. (1) First, the reel 2 is set on the carriage located at the unwinding position downstream of the unwinding device. The reel 2 is rolled and moved as it is from the storage location. The reel 2 is rolled and accommodated in the frame 10 from the front of the carriage 1. Bearing arm 1
Two shafts 5 in total are inserted from the outside of 4 toward both shaft holes of the reel 2 and locked in the shaft holes. And the cylinder 15
Then, the rod 16 is reduced to float the reel 2 from the floor.

(2) Next, both the lengthwise member B and both start ends of the liner R, which is wound on the lower side of the lengthwise member B, are pulled out from the roll member 3 of the reel 2. The starting ends of the long member B and the liner R are passed under the tension roll 25 and then over the feeder roll 20 and lowered vertically downward. After forming the feeder portion 29, the starting end portion of the long member B is sent to the upstream unwinding device and then sent to the servicer.

(3) On the other hand, the starting end of the liner R is taken down from the feeder roll 20 and then taken up by the liner take-up shaft 24. Then, the liner R passes between the peeling roll 26 and the reversing roll 27 and between the reversing roll 27 and the returning roll 28 in the middle between the tension roll 25 and the feeder roll 20, respectively. In this state, the unwinding preparation of the long member B is completed. A slight load is applied to the reel 2 by the brake mechanism 6 for rotation.

(4) When power is applied to the driving roll 19 in this state, the feeder roll 20 and the liner winding shaft 24 rotate in synchronization with each other. The long member B has a feeder portion 29.
Head towards the unwinding device upstream. The liner R is wound around the liner winding shaft 24.

(5) Liner R is tension roll 25
After passing below, the direction is temporarily changed by the peeling roll 26 (at this time, the liner R which is in close contact with the lower surface of the long member B).
Is peeled from the lower surface of the member B). Then, the reversing roll 27 reverses 180 degrees. Further, the direction of the return roll 28 is made the same as the traveling direction of the long member B again, and the long member B
Along with the feeder roll 20. The liner R is reliably peeled off from the long member B by these three rolls. In this state, since it goes to the feeder roll 20, it does not come into close contact with the long member B and then goes to the feeder portion 29 after passing through the feeder roll 20. The liner R is reliably wound around the liner winding shaft 24.
As a result, the long member B is always unwound stably.

(5) When the number of reels 3 on the reel 2 becomes zero, the empty reel 2 must be replaced with a new reel 2. The reel 2 is replaced as follows. After stopping the rotation of the drive roller 19, the rod 1 of the cylinder 15
Extend 6 and gently drop reel 2 onto the floor. The brake mechanism 6 is released and the shaft 5 is removed from the shaft hole of the reel 2.
Then, the empty reel 2 is rolled and moved to a storage location or a winding location for the long member B. On the other hand, a new reel 2 is brought from the storage location, and the unwinding preparation is carried out by the above steps (1) to (3).

The long member B used in this embodiment is a member having adhesiveness and is a member that is always unwound together with the liner. As an example thereof, it is suitable for unwinding a tire constituent member having adhesion such as a belt member, an inner liner, a belt ply, a nylon chafer, and a rubber chafer. In this case, one relatively wide member such as a belt member is wound on the reel. Also, two relatively narrow width members such as a rubber chafer that are to be unwound at the same time are arranged in parallel and wound on a reel so that two members are unwound at the same time.
