Description

[Detailed explanation of the invention] [In industrial use field] The present invention is for the supply device of a band -shaped material with a liner on the surface, and for more details, for example, carcass, belt or sidetretzdo material, for example. A liner is attached to the surface of the material at the material stage, and multiple strips of material wound into rolls can be stacked at the same time. The present invention relates to a feeding device for strip material having a movable cart without a source.

[Conventional technology]

Conventionally, when supplying the above-mentioned tire constituent materials to a tire molding machine, the roll-shaped strip material is directly attached to a supply device equipped with a liner winding device, a material unloading device, a centering device, etc.
The strip material is supplied to the next process while peeling off the liner.

Therefore, in such a feeding device, not only is it difficult to attach and remove the rolled strip material from the feeding device, but also when it becomes necessary to replace the material with another material during use, the material cannot be replaced. The liner could simply be cut, but the liner had to be rewound. Therefore, it takes a lot of time to replace the strip material, and if the material to be newly installed is a material that is in the middle of being used, the undone liner must be rolled up until the material reaches its beginning. Furthermore, it takes a long time to replace materials, etc.
Not only was productivity poor, but there were many problems in terms of burden on workers and safety.

Therefore, as mentioned above, instead of attaching the rolled material to the feeder directly, the material is attached to a movable trolley, which is joined to the main body of the feeder. A feeding device with a cassette-type truck for feeding material is considered, but its structure is extremely complicated and expensive, as it requires a drive source to wind up the liner inside the truck, and the feeding device itself is expensive. At present, it has not been put into practical use because there are many problems with the means of connection.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned current situation, and its purpose is to provide an extremely effective and suitable feeding device for a strip material having a liner attached to the surface, which solves the above-mentioned problems all at once.

[Structure of the Invention] That is, the present invention consists of a movable cart equipped with a plurality of strip material attachment parts and a strip material feeding and liner winding mechanism, and a feeding device main body equipped with a drive source, A locking mechanism is provided at a position where the feeding device main body and the cart face each other to allow the cart to be attached to and detached from the feeding device main body, and when the cart and the feeding device main body are docked via this lock mechanism, the drive source is activated. This is a belt-shaped material supply device characterized by interposing a clutch mechanism connected to and driven by a belt-shaped material feeding and liner winding mechanism.

First, to explain the structure of the truck G, as shown in FIG. The material is hung on a material attachment part 10 such as a square shaft. As shown in FIG. 2, the material attachment part 10 (hereinafter referred to as the square shaft) is rotatably attached to the frame 12 of the truck G via a bearing 11, and a brake pulley 13 is fixed coaxially with the square shaft 10. As shown in FIG. 3, it is fixed to the frame 12 of the trolley G, and by pulling the adjustment knob 15 of the brake band 14, the square shaft 10 is braked, and the small roll 7 can be braked when unwinding the material. It's summery. Note that this brake device is not limited to the above-mentioned structure, and may be of any type as long as it is adjustable. The material 7 unwound with a woven fabric or resin liner is separated by a separating roller 18 which is received by bearings 17, and the liner 8 passes through the two rolls and then again with the material 16 onto the material delivery roll 19. drawn out by The drawn liner 8 is wound around a cell 24 by a square shaft 23 which is interlocked with a delivery roll 19, sprockets 20, 21 (FIG. 2), and a chain 22. The material delivery roll 19 is lined on the surface with rubber or urethane having a large friction coefficient to prevent slippage with the liner 8, and is fixed to the frame 12 by a rotatable bearing 25. In addition, the shaft of the material delivery roll 19 is equipped with the aforementioned sprocket 20.
A drive connection sprocket 26 is attached. The liner winding square shaft 23 is
It is fixed to the frame 12 by a rotatable bearing, and this shaft is equipped with the aforementioned sprocket 21.
However, a torque limiter 27 is attached to eliminate the difference in material delivery speed depending on the winding diameter of the liner, and the sliding of the torque limiter 27 ensures that the liner is always wound with a constant torque. These material feeding and liner winding mechanisms _G1 can be attached to one trolley G for the required number of tire materials, and can be attached to the frame base 28 of the trolley G (which is welded to the frame 12 to form an integral structure). ) is equipped with two fixed wheel wheels 29 and two free wheel wheels 30, so that when separated from the main body H of the supply device, it can move freely without a track.

This driving force transmission mechanism _H1 is installed in the same number as the number of tire materials, that is, the same number corresponding to the number of material mounting stages of the truck G. In the example shown in the figure, there are two stages, but it is possible to have multiple stages.

When the main body H of the supply device and the trolley G are docked, a clutch is activated that automatically drives the material feeding and liner winding mechanism _G1 on the trolley G side using the driving force of the drive source 33 of the main body H of the supply device. The mechanism is
It is not limited to the chain type described above,
For example, instead of the above chain, a driving force transmission means using a clutch mechanism such as a gear type using a gear, a coupling type using a coupling, or a roll type using a roll having a large friction coefficient can be applied.

The trolley G can move freely without track, but
When fixed and used as an unwinding device, it is necessary to fix the carriage G at the same time as the above-mentioned drive connection.

Next, the lock mechanism of the cart G of the supply device main body H
Let me explain about _H2 .

As shown in FIGS. 4 and 5, a lock arm 43 is loosely inserted into a shaft 45 fixed by a bracket 44 so that it cannot be fixed, and one end of the arm is fitted with a rod 31. Matching grooves are cut, and the opposite side of the bracket 44 is constantly tensioned by a tension spring 46, so that the grooves are constantly pushed upward. These brackets 44 and springs 46 are fixed to a base plate 47 embedded in the floor.

There are two lock arms 43 on the left and right.
