Abstract

(57) [Summary] [Purpose] To provide a product supply mechanism capable of stably supplying a product wound on a reel without causing scratches or scratches. [Structure] A reel 1 around which a product is wound, a motor 2 that rotates and stops the reel 1, upper and lower sensors 3 and 4 that send signals to the motor 2 to rotate and stop, and supply by rotation of the motor 2. The feed mechanism 5 for taking in the processed product and the upper sensor 3
It is composed of a rotatable and electrically conductive contact 6 attached to the tip of the product and a product guide 7 attached so as not to interfere with the lower sensor.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a product supply mechanism, and more particularly to a product supply mechanism that automatically supplies a product wound on a reel by a motor and a sensor.

[0002]

[Prior Art]

 Conventionally, this type of product supply mechanism is configured to include a reel on which the product is wound, a motor for rotating and stopping the reel, and a feeding mechanism for taking in the product supplied by the rotation of the motor. ing.

FIG. 4 is a front view showing an example of a conventional product supply mechanism. 5 and 6 are front views showing the operation of the configuration shown in FIG. The product supply mechanism shown in FIG. 4 sends a reel 9 that is rotated and stopped by the motor 10, a feed mechanism 13 that takes in the product 8 supplied by the motor 10, and a signal that rotates the motor 10 when the product 8 contacts. It includes an upper sensor 11 for sending and a lower sensor 12 for sending a signal to stop the motor 10 when the product 8 contacts.

Next, the operation will be described. The product 8 set up to the feeding mechanism 13 is fed by the feeding mechanism 13 in the direction of arrow C in FIG. When the sent product 8 contacts the upper sensor 11, the motor 10 rotates in the direction of arrow D to supply the product 8 (see FIG. 5). When the supplied product 8 contacts the lower sensor 12, the motor 10 stops and the supply is stopped (see FIG. 6).

By repeating the above operation, the product is automatically supplied.

[0006]

[Problems to be solved by the device]

 However, in the above-described conventional product supply mechanism, the product comes into direct contact with the upper and lower sensors, which causes the product to be scratched and the product to be caught.

Further, there is a drawback that it is difficult to adjust the position of the sensor.

The present invention has been made in view of the above conventional circumstances, and therefore an object of the present invention is to provide a new product supply mechanism capable of solving the above-mentioned drawbacks inherent in the conventional technology. To do.

[0009]

[Means for Solving the Problems]

 In order to achieve the above object, a product supply mechanism according to the present invention comprises a reel on which a product is wound, a motor for rotating and stopping the reel, and an upper / lower circuit for sending a rotation / stop signal to the motor. A sensor, a feed mechanism that takes in the product supplied by the rotation of the motor, a flexible bar-like contact point that is provided at the tip of the upper sensor and is free to rotate, and has electrical continuity, and does not interfere with the lower sensor. And the product guide installed as described above.

[0010]

【Example】

 Next, the present invention will be described in detail with reference to the drawings for a preferred embodiment thereof.

FIG. 1 is a front view showing an embodiment of the present invention.

Referring to FIG. 1, an embodiment of the product supply mechanism shown in FIG. 1 is a reel 1 around which a product 8 is wound, a motor 2 for rotating and stopping the reel 1, and a motor 2 for rotating the reel 1. Upper and lower sensors 3 and 4 for sending rotation and stop signals to the upper and lower parts, a feeding mechanism 5 for taking in the product 8 supplied by the rotation of the motor 2, and a free rotation attached to the tip of the upper sensor 3. And a flexible bar-shaped contact 6 having electrical continuity and a product guide 7 mounted so as not to interfere with the lower sensor 4.

In FIG. 2, the product 8 set up to the feeding mechanism 5 is fed by the feeding mechanism 5 in the arrow A direction. When the sent product 8 comes into contact with the contact 6 attached to the tip of the upper sensor 3, the motor 2 rotates in the direction of arrow B to supply the product 8. At this time, since the contact 6 rotates and escapes, the product 8 can be detected because it is not caught or scratched.

Next, in FIG. 3, when the product 8 supplied by the rotation of the motor 2 contacts the lower sensor 4, the motor 2 is stopped and the supply of the product 8 is stopped. At this time, the product guide 7 guides and receives the product 8 that is supplied a lot due to the overrun of the motor 2. Therefore, it is possible to automatically supply the product 8 without the product getting caught on the lower sensor 4 or the product being scratched. Become.

[0015]

[Effect of the device]

 As described above, according to the present invention, the upper and lower sensors are provided with the flexible, contact-free contact point and the product guide, which are freely rotatable, to eliminate product flaws and scratches. It is possible to obtain a stable supply of products.
