Abstract

PURPOSE:To prevent a wrinkle, fold, etc., of protective paper by constituting a device to insert the protective paper to protect the surface of a cutting board of a stainless steel sheet and others while the cutting board is transported on a transport line so that the head end part of the protective paper is pulled out by a suction device and put out. CONSTITUTION:By actuating a pay-off reel arranged below a roller table 2 to transport a cutting board 1, protective paper 4 is fed in a sliding guide 9 through a reflector roll 5, pinch roll 6 and others and cut off in specified length by a paper cutter 8. Thereafter, when the head end part of the protective paper is slightly put out from the pass line of the roller table 2, the head end of the protective paper 4 is caught by the head end of the cutting board 1 and pulled out, and the protective paper 4 is tightly adhered on the back surface of the cutting board 1. At the time of pulling the head of the protective paper 4, a suction hood 11 is provided on the upper part of the sliding guide 9, a tensile force is given to the head end of the protective paper 4 by a suction force generated by actuation of a suction blower 13, and in this state, the head end of the cutting board is engaged.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically inserting protective paper for cutting boards.

[0002]

2. Description of the Related Art Conventionally, when stacking cut sheets such as stainless steel plates and surface-treated steel plates one by one, a protective paper for protecting the surfaces is inserted while being continuously flown into a conveying line. .. A brief explanation of such a protective paper automatic insertion device will be given below with reference to FIG.
Coil-shaped protective paper 4 rewound by a payoff reel 3 provided below a roller table 2 for transporting
Is sent out by a pinch roll 6 via a deflector roll 5, and its tip is inserted by a compressed air blowing nozzle 7 into a threading guide 9 via a paper cutter 8 and cueing threading is performed on the upper surface of the roller table 2.

Then, when the leading end of the protective paper 4 is slightly above the path line of the roller table 2, the protective paper 4 is cut by the paper cutter 8. Then, the leading edge of the protective paper 4 is hooked by the leading edge of the cutting plate 1 which is conveyed in the direction of the arrow F, and further conveyed while being in close contact with the back surface of the cutting plate 1, and is piled by a piling device (not shown). To be done.

[0004]

By the way, in the above-mentioned prior art, since it is impossible to send the protective paper 4 in a state in which tension is applied, the protective paper 4 may be wrinkled or cannot be fed straight. There were many troubles such as fluttering of the protective paper 4, and due to these, there were many troubles such as being entangled around the automatic insertion device or jumping out from the threading guide 9, which required a great deal of effort to collect it. ..

SUMMARY OF THE INVENTION It is an object of the present invention to provide a device for inserting a protective paper for a cutting board, which is made in order to solve the above problems of the prior art.

[0006]

SUMMARY OF THE INVENTION The present invention provides a payoff reel for rewinding a coil-shaped protective paper, a threading guide for guiding the tip of the protective paper to a roller table for transporting a cutting plate, and the protective paper. Is an automatic insertion device of protective paper for a cutting plate, which comprises a suction device for cueing the tip of the protective paper to the upper surface of the roller table and a cutting machine for cutting the protective paper into a predetermined length.

[0007]

[Operation] According to the present invention, since the suction device is provided above the threading guide for guiding the protective paper to the roller table to suck the leading end of the protective paper, it is possible to apply tension to the protective paper. Therefore, the protective paper can be smoothly moved to the upper surface of the roller table without any wrinkles or folds, and without causing protrusion, winding, or catching around.

EXAMPLE An example of the present invention will be described below with reference to FIG. In the drawings, the same members as those in the conventional example are designated by the same reference numerals and the description thereof will be omitted. In this figure,
Reference numeral 11 denotes a suction hood provided on the upper part of the threading guide 9 and is connected to the suction duct 12. 13 is a suction duct
The suction blower is attached to be coupled to 12, the reference numeral 14 is a discharge duct, and the reference numeral 15 is a variable speed type drive motor for driving the suction blower 12. 16 is an intermediate guide.

The operation of the automatic insertion device of the present invention having the suction device 10 thus constructed will be described below. The payoff reel 3 is operated to feed the protective paper 4 to the threading guide 9 via the reflector roll 5, the pinch roll 6, the intermediate guide 16 and the paper cutter 8. At the same time, the drive motor 15 is started to drive the suction blower 13. At the time when the front end of the protective paper 4 is inserted into the threading guide 9, tension is applied to the front end of the protective paper 4 by the suction force from the suction hood 11, and the front end of the protective paper 4 travels straight inside the threading guide 9. .. The leading end of the protective paper 4 is located on the upper surface of the roller table 2, and tension is applied by the suction force from the suction hood 11 so that the protection paper 4 is aligned with the leading end of the cut plate 1 which is conveyed while maintaining a straight state. The paper cutter 8 is operated to cut the protective paper 4 at that position. The roller table 2 is operated to convey the cutting plate 1. Then, by moving with the tip of the protective sheet 4 hooked on the tip of the cutting board 1 or with the tip aligned,
The protective paper 4 adheres to the entire back surface of the cutting board 1. The cut plate 1 is conveyed with the protective paper 4 in close contact with it, and is piled in a piling device.

In the above embodiment, the drive motor 15
Since the variable speed type is used, it is possible to adjust the suctioned air volume and pressure to the optimum conditions depending on the type and size of the protective paper 4 used. Further, although the intermediate guide 16 is provided between the pinch roll 6 and the paper cutter 8, the conventional compressed air blowing nozzle 7 may be used as it is.

[0011]

As described above, according to the present invention, tension is applied to the tip of the protective paper so that it can be pulled out, so that the tip of the protective paper is free from wrinkles and folds. Cue-threading can be performed without jumping out, wrapping, or getting caught in the surroundings, which makes it possible to insert protective paper smoothly and reduce the load required for collecting problems in the past. It is possible to Further, since the passage of the protective paper is sucked by the suction hood, it is possible to collect paper dust and the like generated when the protective paper is cut, which also has the secondary effect of contributing to the improvement of the working environment. ..
