Description

[Detailed Description of the Invention] The present invention relates to a method for attaching a protective cover to the cover of a book when it is inserted into a case, and more specifically to a method for attaching a protective cover that can facilitate attachment of the protective cover. It is.

Conventionally, when inserting a book into a case, a protective cover made of paraffin-like thin paper is first attached to the cover, and then the book is inserted into the case.

This protective cover is cut to the size of the cover and has a fold formed in advance at the border between the front side of the cover and the part that is folded from the front side to the back side of the cover, and when inserted into the case. Workers installed the protective covers one by one while inserting inserts such as reader reply postcards, order and sales cards, etc.

Therefore, even an experienced person could only produce about 20 books per minute, resulting in poor work efficiency and high work costs. The purpose of this invention is to eliminate the above-mentioned drawbacks, and its feature is that a seat body with a V-shaped groove is provided with a crease that bends toward the inside of the cover when attached to the cover. Insert the protective cover, place the book to which this cover is to be attached on the protective cover, spray fluid onto the bent end of the protective cover to position this part inside the cover, and then attach the rotating parapet. To provide a method for attaching a protective cover to a cover by bending the cover inside the cover while generating static electricity through friction and causing the cover to be charged and adsorbed to the inner surface of the cover.

The present invention and one embodiment shown in the drawings will be described in detail below. FIG. 1 is a perspective view of a tool for carrying out the present invention. This cover mount has a seat 1 which is made of a heavy material such as metal and has a rectangular shape whose long sides are sufficiently longer than the height of the book. form,
This seat body has an L-shaped groove 2 whose sloped surface length is equal to the width of the cover, and an end portion of this V-shaped groove is engaged so as to close this groove, as shown in FIGS. 2 and 3. A stop wall 3 is integrally formed, and a back cover material 4 made of an elastic member such as sponge is adhered to the bottom of the structure with a suitable adhesive.

The protective cover attachment tool of the present invention has the above-mentioned configuration.Next, a procedure for attaching a protective cover to a book using this attachment tool will be explained.

First, as shown in Fig. 4a, paraffin paper or the like is placed in the V-shaped groove 2 in advance with a width equal to the height of the book to be installed, and a width that is equal to the height of the book, but the thickness of the cover is equal to the height of the book. Approximately 3 width
．． A protective cover 6 cut in advance into a rectangle about five times the length is placed in contact with the sloped surfaces 5a and 5b and the back cover material 4, and the end surface is in contact with the locking wall 3, and then the protective cover 6 is cut into a rectangle approximately five times as long as the length shown in FIG. 4b. As shown in FIG. 4c, the book 7 is placed on the protective cover 6 in the L-shaped groove 2, and as shown in FIG. 2, and as shown in FIG.
5b, the content part 9 of the book is held by a holding means (not shown), and airflow is blown onto the folded end of the protective cover 6 from the nozzles 10a, 10b as shown in FIG. 4e. This portion is pressed and bent inside the covers 8a and 8b using fluid pressure.

At the same time as this pushing and bending operation, the movable rods 12a and 12b with hubs 11a and 11b attached to their tips are lowered as shown in FIG. cover 6 to cover 8a while causing
, 8b, and charge-adsorb this cover to the inner surfaces of the covers 8a, 8b, and then raise the moving rods 12a, 12b as shown in FIGS. 4G and 4h. The attachment of the protective cover is completed by closing the covers 8a and 8b on which the protective cover 6 is charged and adsorbed, and taking out the book 7 from within the letter-shaped groove 2 of the seat body 1. Note that when separating the hubs 11a, 11b from the cover 6, by applying an AC high voltage to the hubs 11a, 11b through a high resistance member, the cover 6 and the hub can be easily separated.

As described above, the present invention includes a seat body having a V-shaped groove, and a protective cover that is folded inwards from the cover when attached to the cover, and a method for attaching the cover on top of the protective cover. After placing the folded end of the protective cover on the inside of the cover by spraying fluid on the folded end of the protective cover and positioning this part on the inside of the cover, the rotating hub is used to rub the cover and generate static electricity while pushing the cover inside the cover. Since the protective cover is attached to the cover by bending it and attaching the cover to the inner surface of the cover with an electrostatic charge, the protective cover can be attached more accurately and efficiently, and the structure is simple and can be processed by casting, making it possible to reduce the cost. It has the following effects.

Claims (1)

[Claims] 1. Insert a protective cover with a fold that folds inward when attached to the cover into a seat body with a V-shaped groove, place the book to which this cover is to be attached on top of this protective cover, and then After spraying fluid on the folded edge to position this part on the inside of the cover, use a rotating puff to rub the cover to generate static electricity while bending the cover to the inside of the cover. A method for attaching a protective cover, characterized in that the cover is electrostatically adsorbed and the protective cover is attached to the cover.
