Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an apparatus for folding and bonding paper pieces.

[Background of the Invention] In recent years, paper impregnated with resin has been developed. When this paper is folded in two and heated and pressed, it adheres as if it were a single sheet of paper, and if it is peeled off, the printed surface will not be damaged even if printed on the adhesive surface. New uses have been developed to replace postcards.

[Prior Art] Conventionally, however, a method has been adopted in which folding and bonding of resin-impregnated paper are manually folded in advance by hand, and two stacked pieces of paper are manually sent to a single heater and heat-pressed.

[Problem to be Solved by the Invention] According to the conventional method, a sheet of paper folded manually is manually fed to the heater by hand, so that much labor is required for folding and bonding. At the same time, work efficiency is poor, and automation and labor saving are strongly desired.

[Means for Solving the Problems] The characteristic feature of the present invention is that a duct having a space into which a paper piece can be inserted between both side walls, and formed at an intermediate portion of the duct and penetrates both side walls of the duct. An insertion hole formed as a paper feeder for intermittently feeding a piece of paper into the duct,
A sliding device is provided on one side of the insertion hole of the duct so as to insert a chopper through the insertion hole, and a sliding device is provided on the other side of the insertion hole of the duct and is folded in half by the chopper. And a heating and crimping device for heating and compressing the sent-out piece of paper, and a folding and bonding device for the piece of paper.

[Operation] When the paper impregnated with the resin is intermittently fed into the duct 1 from the paper feeding device 3, the sliding device 4 is operated in synchronization with the paper feeding into the duct 1, and the chopper 12 is inserted into the insertion hole. 6, the sheet 2 is folded in two and sent out to the sheet heating / compression device. The sheet 2 sent to the sheet heating / compression device is fed by a feed roller set 16 while being heated by a heater block 17.
Is heated and pressed, and is adhered and sent out by a final pressure roller so that the entire surface is in close contact.

[Example] Hereinafter, an example will be described with reference to the drawings.

1 to 3, reference numeral 1 denotes a duct, and the duct 1 has a space between the side walls 1a and 1b which can receive a sheet 2;
It is erected so as to open the top surface and close the bottom surface.

An insertion hole 6 is formed in the middle of the duct 1 through the side walls 1a and 1b, and an operating piece 8 of a limit switch 7 is inserted into the bottom of the duct 1. The detection of the supply of the paper sheet 2 to the apparatus and the detection signal are input to a counter (not shown) to count the number of sheets fed.

On the other hand, above the duct 1, a paper feed device 3 that feeds a sheet 2 into the duct 1 is arranged.

The paper feed device 3 is composed of a paper feed cassette 9, a feed roller 10, a paper feed belt 11, and the like. The feed roller 10 is driven intermittently as described later to separate the paper pieces 2 at a constant interval. The air is supplied into the duct 1.

Reference numeral 4 denotes a sliding device. The sliding device 4 includes a slide 13 having a chopper 12 disposed on one surface of the insertion hole 6;
A guide for guiding the slide 13 to move linearly.
14 and a crank arm 15a for reciprocating the slide 13
And a connecting link 15b for connecting the slide 13 and the crank arm 15a. By driving the motor M, the slide 13 is slid along the guide 14, and the chopper 12 is moved into and out of the insertion hole 6. It has become.

A cam switch (not shown) is provided on a rotating shaft (not shown) connected to the output shaft of the motor M (a rotating shaft to which the crank arm 15a is attached), and the feed roller 10 is driven by a signal from the switch. Is turned on, and the feed roller is driven by a motor (not shown). This cam switch may be replaced with an angle detector such as an encoder.

Reference numeral 5 denotes a sheet heating / compressing device, which is provided on the opposite side of the chopper 12 with the insertion hole 6 interposed therebetween. The sheet heating / compressing device 5 is provided with one or more sets of rubber feed rollers 16 facing up and down and heater blocks 17 facing up and down alternately. The pressure roller 18 is used.

The distance between the feed rollers 16 and the distance between the feed roller 16 and the pressure roller 18 are set to be substantially equal to or slightly shorter than the length of the folded sheet 2. Also,
The lower side of the heater block 17 is fixed, and the upper side is swingably supported. When the folded paper piece 2 is supplied between the upper and lower heater blocks 17, the receiving opening is opened to facilitate the receiving of the paper piece 2. At the same time, a predetermined gap through which the paper piece 2 can pass is secured by shims or the like.

 Next, the operation of folding and adhering a piece of paper will be described.

First, a start switch (not shown) is turned on, and the feed belt 11 of the feed device 3 and the rubber feed roller 16 and the metal roller 18 of the sheet heating / compression device 5 are started. These are always rotated at a constant speed during operation.

The heater block 17 is also energized to heat the heater block. When the heater block 17 is heated to a set temperature at which the heater block 17 can be bonded,
When a certain period of time has elapsed from the time of turning on, the electromagnetic clutch is turned on by a command from a switch or a time relay (not shown) and the sliding device 4 is operated by the motor M.
The clutch connected to the feed roller 10 is turned on by a signal from a cam switch (rotation angle signal generator) provided on the rotation shaft of the crank arm 15a, and the roller 10 is rotated for a certain period of time. Send 2 out.

The sent paper piece 2 is fed into the duct 1 from above through the paper feed belt 11. At this time, the feed roller
The sheet 11 is driven until the leading end of the sheet 2 reaches the paper feed belt 11, but thereafter, the clutch is turned off to be free and rotated by the frictional force with the sheet 2 being taken.

Then, when the paper piece 2 is completely inserted into the duct 1,
A chopper 12 adjusted in advance so as to project at the same time as this is inserted into the insertion hole 6. As a result, the sheet 2 in the duct 1 is folded in half in the middle, and is sent out between the rubber feed rollers 16 rotating with the fold at the top.

At this time, after the chopper 12 is protruded toward the feed roller 16 and then pulled back again, since the frictional force between the feed roller 16 and the sheet 2 is larger than the frictional force between the chopper 12 and the sheet 2, The sheet 2 is not pulled back with the chopper 12.

In this manner, the paper sheet 2 fed between the feed rollers 16 is pushed between the heater blocks 17 by the rollers 16 and heated.

In this embodiment, since the feed roller 10 and the heater block 17 are provided for three sets, this process is repeated three times. In this process, the sheet 2 is pressed while being heated.
The resin impregnated into the pieces of paper 2 dissolves appropriately, and the resin acts as an adhesive to bond the folded paper pieces 2 to each other.

Finally, the metal pressure roller 18 provided at the last stage
Through the gap, a predetermined pressure is applied to ensure the close contact and then send it out.

Thereafter, the above steps are repeated to automatically feed / fold /
Perform bonding.

At the bottom of the duct 1, there is provided a limit switch 7 which is operated by the weight of the paper sheet 2, and its signal is inputted to a counter (not shown) to count the number of processed sheets or The set predetermined number is compared with the processing number, and when the processing number matches the set number, the operation is automatically stopped.

Needless to say, this limit switch can be replaced with another detector such as a photoelectric switch.

[Effects of the Invention] According to the paper sheet folding / adhering apparatus of the present invention, the automatically fed paper sheet is folded in two by a chopper and continuously bonded by a heating / compression bonding apparatus. The work of feeding paper to the heater for heating and bonding can be automated and labor-saving, and the work efficiency is markedly improved.

In addition, there is an effect that the mechanism is simple and the device can be manufactured relatively inexpensively.
