Abstract

PURPOSE:To securely connect a strip material by stopping the ends of one strip material on a plate member and then connecting its end to the end of the next strip material on the plate member when a soft strip material such as a tire is connected. CONSTITUTION:When a soft strip material is fed to the next process, one end a1 of a strip material (a) which moves toward the discharge end, passes an optical axis of a photoelectric switch 2 on a plate member 1. When the photoelectric switch 2 detects lack of material, it operates a clutch brake 9 and a chain 8 runs idle. At the same time, a discharge roller 3 is thrown on the brakes through a chain 8' and is brought to a stop. Therefore, the soft strip material (a) automatically comes to a halt with the end (a1) remaining on the plate member 1. A new roll material (a) is then drawn. Its end (a2) is securely and easily connected to the end (a1) of the proceeding material on the plate member 1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for connecting flexible strips of material.

For example, when supplying tire constituent materials wound on an unwinding roll to a forming drum via a material supply device, if the material runs out during the supply, conventionally the material supply device is manually stopped and any part of the device is turned off. At this point, the tip of the next tire component material is connected to the end of the previous material.

Therefore, during material connection work, the ends of each material to be connected are not stable and workability is poor, and there are problems such as poor connection status after material connection, and the state of material shortage is also artificial. The current situation is that this has become a factor that hinders or harms the improvement of quality and productivity, such as checking the quality of the product and increasing the burden on workers.

The purpose of the present invention is to solve the above-mentioned problems, and to provide flexible belt-shaped materials such as tire constituent materials to the next process.
An excellent method and method for connecting flexible strip-like materials that automatically detects the state of out-of-material and stops the feeding device, while also making it possible to easily and reliably join each material on a board member. The goal is to provide the equipment.

The feature is that when supplying a flexible strip-shaped material to the next process, a sensor detects the end of the strip-shaped material moving toward the discharge side on a plate-shaped member, and the terminal from this sensor is detected. The detection signal causes the end portion of the strip-shaped material to stop on the plate-like member, and then the tip of the next strip-shaped material and the end portion are connected on this plate-like member.

Hereinafter, the present invention will be explained in detail by way of examples with reference to the drawings.

First, to explain the apparatus directly used for carrying out the method of the present invention, the figure is a front view illustrating a flexible strip-like material connecting apparatus according to an embodiment of the present invention.

In the figure, E denotes a flexible strip-shaped material connecting device according to an embodiment of the present invention. and a sensor 2 for detecting the end portion a of the strip material a is provided above the intermediate portion of the plate-like member 1, and this sensor 2 and the driving means F are electrically connected. has been done.

To further explain this structure, the sensor 2 uses a photoelectric switch in this embodiment, and the strip material a
When the terminal portion a1 of the photoelectric switch passes through the light emitting portion of the photoelectric switch, the light is reflected by the reflecting plate 2a provided on the plate member 1, and the photoelectric switch is activated to stop the driving means F. ing.

Further, as shown in this embodiment, the driving means F for the unloading roll 3 is composed of a motor 7 and a clutch brake 9, and the driving force of the motor 7 is provided by a chain 8.
It is transmitted to the clutch brake 9 via the chain 8', and further transmitted to the delivery roll 3 via the chain 8'. In this embodiment, the driving force of the motor 7 is applied to the chain 7 on the roll 4 on the unwinding side of the strip material a.
At the same time, the take-up roll 10 of the liner 6 can also be driven via a chain 8'' and a friction plate 11.

In addition, 12 in the figure is a wire around which the strip material a is wound, and 16
is an unwinding shaft to which this reel 12 is attached. Therefore, by rotating the motor 7, the unloading roll 6
rotates via the chain 8, clutch brake 9, and chain 8' to carry out the material a. At this time, the clutch brake 9 is in a state where the clutch is engaged and the brake is released, and power can be transmitted. Also, the unwinding side roll 4
rotates via the chain 8'' to carry in the material a, and the liner take-up roll 10 rotates via the chain 8'' to wind up the liner 6. At this time, the liner winding roll 10 has a friction plate 11 on the same axis, and has a structure that the liner 6 can be wound at a constant speed even if the winding diameter changes. Although it is possible to drive the carry-out side roll 6 and the unwinding-side roll 4 separately, it is more advantageous to drive them in a connected manner as shown in the figure in order to prevent expansion and contraction of the strip material a.

Next, a description will be given of the operation of connecting the end portion of a strip of material to the tip of a new material when the strip material is finished. When the end portion a1 of the strip material a passes through the sensor, that is, the optical axis of the photoelectric switch 2 on the plate member 1, the photoelectric switch 2 detects that the material is out and operates the clutch brake 9, and the chain 8
At the same time as idling, the delivery side roll 3 is braked via the chain 8' and stopped. Therefore, the strip-shaped material a automatically stops with the end portion a1 placed on the plate-shaped member 1.

On the other hand, the unwinding roll 4 and the liner winding roll 10 continue to rotate, and winding of the liner 6 is completed. Further, the photoelectric switch 2 detects that the material is out, and the clutch brake 9 is operated, and at the same time, an alarm device is activated to notify the operator that the material is out. The operator thereby removes the core of the reel 12 from the unwinding/gift 13, and removes the material a wound into a new roll.
The terminal part a is replaced by a belt-shaped material a, which is unwound and its leading end part a2 is stopped at a predetermined position on the plate-shaped member 1 as described above.

can be easily connected with. It is also possible to automate the connection work.

As described above, the present invention, when supplying a flexible strip material to the next process, detects the end portion of the strip material moving toward the delivery side with a sensor on a plate-shaped member,
An end detection signal from this sensor causes the end of the strip-shaped material to stop on the plate-shaped member, and then the tip of the next strip-shaped material is connected to the end on this plate-shaped member. Therefore, when supplying flexible strip materials such as tire constituent materials to the next process, the state of material shortage is automatically detected and the movement of the strip material is stopped, while the joining work of each material is performed on the plate member. This can be done easily and reliably.

Therefore, the workability of material connection work can be significantly improved, the connection state after connection can be improved, and not only quality and productivity can be improved, but also productivity for people can be greatly improved.
