Description

[Detailed Description of the Invention] The present invention relates to a protective cover attachment that is attached to the cover of a book when it is inserted into a case, and more specifically, to a protective cover attachment 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 a fold is 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. When loading the books, workers attached the protective covers one by one while inserting 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 present invention aims to eliminate the above-mentioned drawbacks, and its characteristics include providing a V-shaped groove in a rectangular seat body, and furthermore, an inclined surface formed by the V-shaped groove. An extension member that is continuous with the V-shaped groove is attached to the seat body to form a substantially flat bottom surface at the bottom of the V-shaped groove, and an electrode plate is attached to the surface of the extension member that extends the V-shaped groove for protection. The present invention provides a protective cover mounting tool which charges the cover with static electricity through the cover and attaches the cover to the cover by adhering the cover to the inner surface of the cover of the book placed in the groove. be.

An embodiment of the present invention shown in the drawings will be described in detail below.

FIG. 1 is a perspective view of a protective cover fixture of the present invention. This cover fixture forms a rectangular seat body 1 made of a material with heavy specific gravity, such as metal, and whose long sides are sufficiently longer than the height of the book. death,
This seat body has a V-shaped groove 2 whose sloped surface length is about half the width of the cover, and a V-shaped groove 2 at the end of the groove to close this groove as shown in FIGS. 2 and 3. A locking wall 3 is integrally formed on the bottom of the groove, and a back cover material 4 made of an elastic member such as a sponge is attached to the bottom of the groove with a suitable adhesive. , 5b is an inclined surface longer than the width of the cover, and extension members 6a and 6b made of an insulating material such as synthetic resin are connected, and the extension members are attached to the inclined surfaces 7a and 7b of the extension members so as to penetrate through the extension members. Electrode plates 9a and 9b connected to the electrode rods Ba and 8b are attached so that the front cover can be charged with static electricity, and through holes 10a and 10b are formed in the continuous portion of the seat body 1 and the extension members 6a and 6b, and inside these through holes Elastic members 11a, 11 are provided on the end surface for closing the cover opened to
Insert the press rods 12a and 12b with the screws 12a and 12b attached thereto, and also make a hole 13 at the bottom of the V-shaped groove that passes through the seat body 1 and the back cover material 4.
The plunger rod 15 of the plunger 14 is inserted into this hole and the book placed in the V-shaped groove 2 can be pushed out.

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. 4, the V-shaped groove 2 must have a width equal to the height of the book to which paraffin paper or the like is to be attached in advance, and approximately the width of the cover, although this varies depending on the thickness of the book. After the protective cover 17, which has been cut in advance into a rectangle approximately 3.5 times the length, is brought into contact with the inclined surfaces 5a, 5b and 7a, 7b1 and the back cover material 4, and its end surface is brought into contact with the locking wall 3, A positive or negative high voltage (DC 3000) is applied to the electrode plates 9a and 9b from the electric circuit 16 to charge them with static electricity.

Next, as shown in FIGS. 5 to 7, place the bookshelf 18 on the protective cover 17 in this V-shaped groove 2 from the back cover side so that one end is in contact with the locking wall 3 as before. First, both covers 19a and 19b are placed on the inclined surface 5a.
, 5b and 7a, 7b, and press the spine 21 against the spine cover material 4 through the protective cover 17 with the inside part 20 of the book, the protective cover 17 charged with static electricity will be removed. Both ends of the protective cover 17 that sticks to the covers 19a and 19b and protrudes outward from the V-shaped groove 2 are attached to the cover 1.
Fold it inside 9a and 19b as shown by the arrow. At this point, a drive mechanism (not shown) is actuated by the operator's operation, and the push rods 12a12b enter the premises from the left and right to close the opened covers 8a and 8b, and then the plunger 14 is energized and the plunger rod 15 is closed. Push out the writing paper with the protective cover through the letter-shaped groove to complete attaching the protective cover. In this case, it is more effective to install the protective cover fixture on a rotary workbench so that it can rotate, and to work by inserting about 10 protective covers into the letter-shaped groove 2 at a time. Yes, as shown in FIG.
Folds 173a and 173b are used in advance at the boundaries between 72b and the portion 172 corresponding to the covers 19a, 19b and spine 21.

FIG. 8 shows how the protective cover 17 is attached to a book whose cover width is longer than the entire length of the inclined surfaces 5a, 5b, 17a, and 7b, and in this case, the installation procedure is the same as that shown in FIGS. 4 to 7. It can be installed as As described above, the present invention provides a rectangular seat body with a V-shaped groove, further attaches to the seat body an extension member that is continuous with the slope formed by the groove, and the V-shaped groove. A substantially flat bottom surface is formed at the bottom of the groove, and an electrode plate is attached to the surface of an extension member extending the groove, so that the front cover is charged with static electricity through the protective cover. Since the cover is attached to the cover by electrostatically attracting the cover to the inner surface of the cover of the bookcase placed inside, the protective cover can be attached more accurately and efficiently, and the structure is simple and can be processed by molding. It has the advantage of being inexpensive.
