In particular, the present invention relates to a small-sized newspaper advertisement inserter suitable for inserting an advertisement in a newspaper store.

[Prior Art and Problems Thereof] A conventional newspaper advertisement folding machine folds several types of advertisements and bundles them into one bundle, and these bundled advertisements are manually inserted into a folded newspaper. The number of pages in a newspaper varies depending on the newspaper brand, and there are many types of advertisements in one bundle, from large advertisements to small advertisements. The number of advertisements also differs depending on the day. When the number is small, it is 2-3, and when it is large, 20
When the number of advertisements is small, when the number of advertisements is small, the upper surface becomes substantially horizontal, but when the number of advertisements is large, the upper surface is not horizontal, and the height difference is nearly double.

As described above, a mechanism for inserting advertisements having different numbers of sheets between two-folded newspapers having different numbers of sheets becomes complicated, and conventionally, it has not been possible to realize with a small device.

In addition, an advertisement is usually folded in half with a B4 size advertisement, and various other advertisements are sandwiched between the advertisements to form a bundle. A bi-fold advertisement that bundles other advertisements is called a mount, but if this mount is small, for example, if the portion of the advertisement sandwiched between the mounts is only about 1/3,
Since the parts of the advertisement that are not sandwiched between the mounts are disjointed, it is difficult to distinguish where the bundle is.

Therefore, when an advertisement folded in a bundle is automatically inserted between the folded newspapers, there is a problem with a means for reliably extracting a bundle of advertisements having different conditions as described above.
Conventionally, such a newspaper advertisement inserter has not been put into practical use.

The present invention has been made in view of such problems,
It is an object of the present invention to provide a newspaper advertisement inserter having a simple structure that can reliably take out advertisements one by one and insert them into a newspaper.

Pallet, a newspaper advertisement pallet on which a plurality of newspaper advertisements are placed, a pair of plates that take two positions between a closed position and a position that opens in a V shape to form a hopper, and this pair of plates A vacuum sucker provided in each of them, a newspaper insertion means for taking out a part of the folded newspaper on the newspaper pallet and putting it in the hopper, and a part of taking out a newspaper advertisement on the newspaper advertisement pallet. It has a newspaper advertisement insertion means to be inserted into the hopper and a discharge means for discharging the newspaper with the advertisement folded in the hopper by opening the bottom of the hopper, and the newspaper insertion means has a plurality of means for grasping the end portion of the newspaper. Be equipped with the nails The head, a suction cup for sucking the end of the uppermost newspaper on the newspaper pallet and lifting it near the head, and a head rotating means for rotating the head to throw the newspaper into the hopper. It is characterized by having.

[Operation] In the present invention, with the pair of plates of the hopper opened in the V shape, the newspaper is inserted into the hopper by the newspaper insertion means,
After that, the pair of plates of the hopper are closed, and the newspaper is sucked by a vacuum suction cup provided on the plates. Then, when the pair of plates is opened in a V shape, the folded newspaper is opened. Therefore, when a part of the newspaper advertisement is taken out by the newspaper advertisement insertion means and is inserted into the hopper, this newspaper advertisement is inserted between the newspapers. After that, the bottom of the hopper is opened by the ejecting means to eject the newspaper in which the advertisement has been folded. In this way, the insert advertisement can be inserted between the newspapers with a very simple structure.

As a means for extracting the advertisement part by part, there is one described in claim 3. That is, the lifting suction cup lifts the edge of the uppermost advertisement, and then inserts a plurality of nails of the head below the edge of the lifted advertisement to grab it.
After that, by rotating the head by the head rotating means, it is possible to reliably extract only a part of the advertisement and put it in the hopper.

The claws 31 fixed to the glove close and grab the edges of newspapers and advertisements. The third pulley 26 from the left end is 90% closed, the pulley 26 on the right side is 80% closed, the pulley 26 on the right side is 60% closed, and the 10th to 12th pulleys from the left end are almost in operation. You will be left unattended.

Next, when the air cylinder 19b is actuated, all the claws 31 fixed to the third to twelfth pulleys 26 from the left end in FIG. 5 are closed, and the claws 31 of the thirteenth to twelfth pulleys 26 are respectively set to 9 as described above. The closed state is 80%, 60%, ...

Next, the air cylinder 19c is activated, and similarly, all the claws 31 fixed to the 13th to 21st pulleys 26 from the left end are closed.
The claws 31 fixed to the thirtieth to thirty pulleys 26 sequentially take a state from a closed state to an open state.

Furthermore, when the air cylinder 19d is activated, all pulleys 2
The claw 31 fixed to 6 is closed. In this way, by sequentially operating the air cylinders 19a, 19b, 19c, 19d,
The claw 31 fixed to the pulley 26 moves like a hundred feet and closes to grab the edges of newspapers and advertisements.

In this way, after the newspapers and advertisements are firmly gripped by the heads 10 and 65, the air cylinder 33 shown in FIG. 9 is mixed to free the weight 32. Therefore, the incident angle of the suction cup 68 is also determined based on the distance of the support point of the weight 32 from the advertisement extraction position. For example, this angle of incidence is 84 °
And

When the arm head 10 shown in FIGS. 1 and 4 grabs a newspaper, the cylinder 6 is actuated and retracts by 30 mm,
Retreat out of 10 circular orbits. After that, the air cylinder 13 is operated to insert the head 10 into the hopper composed of the plates 71 and 72, and the air cylinders 19a to 19d of the head 10 are simultaneously operated to simultaneously operate the claws 31 of the head 10. Drop the open newspaper into the hopper. Then, the head 10 is returned to the predetermined position.
Next, the movable plate 72 of the hopper is moved by the air cylinder 76 to close the hopper, and four newspapers are sucked by the suction cups 91 provided on each of the fixed plate 71 and the movable plate 72. After that, the movable plate 72 is returned to the original position, the hopper is opened, and the folded newspaper is opened. After that, the advertisement held by the arm head 65 is inserted into the hopper by the operation of the air cylinder 69, and then the pawl 31 is simultaneously opened to open the advertisement in the newspaper waiting in the hopper. throw into. Then the head
As soon as 65 returns to the home position, the air cylinder 77 is activated, the bottom 74 of the hopper is opened, and the newspaper is a guide 75 as a shooter.
And is discharged onto the newspaper discharge pallet 80. Then, after a large number of newspapers after the insertion of advertisements are placed on the pallet 80, the pallet 80 descends and the bundle of newspapers is taken out.
