Description

[Detailed Description of the Invention] The present invention relates to a gluing machine for binding a book by applying a hot-melt type adhesive to one side of a stack of paper sheets made of a large number of stacked papers.

Specifically, a glue storage tank equipped with an applicator roller and a heater is supported freely in the front and rear of the machine.
The present invention relates to a gluing machine in which an application roller is rotated by the movement of the tank, the adhesive is housed in the tank, and melted by a heater is applied to one side of the bundle of paper sheets.

A conventional gluing machine, for example, as disclosed in Japanese Utility Model Publication No. 52-57180, has a pair of rails on the machine body, supports four running wheels on the tank, and has a heater provided on the tank. As a mechanism for supplying power to the machine, a movable body having a pair of rotating bodies is freely supported on the machine body, and a cord and a string-like body each having one end fixed to the machine body are hung from each of the rotating bodies, Even if the tank moves, the cord is prevented from being pulled or loosened.

However, in the gluing machine configured as above,
The tank movement system and the power supply system to the heater are mechanically formed separately, which increases the number of parts, complicates the structure, increases costs, and increases the overall weight. There was a problem with poor handling during transportation.

The present invention was devised in view of the problems of the conventional examples as described above, and the purpose is to provide a gluing machine that has a small number of parts, has a simple structure, can reduce costs, and can also reduce weight. The present invention is characterized in that it focuses on the movable body of the power supply system and uses the movable body as a rail for the tank.

Next, embodiments of the present invention will be described based on the drawings.

Although not shown in the drawings, the gluing machine shown in FIG. 1 constitutes a bookbinding machine together with a paper clamping device for clamping a bundle of paper sheets, as is known.

The basic structure of the glue applicator is as known, and a glue storage tank 4 equipped with an applicator roller 2 and a heater 3 is attached to a horizontally elongated box-shaped machine body 1 via a base 5. A movable body 8 is mounted on one side of the body 1 in the width direction, and has first and second rotating bodies 6 and 7, each of which is a pair of pulleys. on the other side of the body 1 in the width direction,
A chain 9 is stretched, and an operating lever 10 provided on the base 5 is protruded to the outside of the machine body 1. By reciprocating the lever 10, the base 5 and the tank 4 can be moved to the front and rear of the machine body 1. move in the direction
By this movement, the application roller 2 is rotated in relation to the chain 9, and the adhesive in the tank 4 is applied to one side of the bundle of paper sheets.

Therefore, the moving body 8 shown in the drawings uses a pair of strip plates 81 and 82 having a length approximately half of the length of the body 1, and these strip plates 81, 82,
A collar 83 and a support are provided between the first rotating body 6 in contact with the bottom wall 1a of the fuselage 1 and the second rotating body 7 floating on the bottom wall 1a of the fuselage 1 at both ends in the length direction between 82 and 82. It is rotatably supported via a shaft 84, and one end side in the length direction of the strip plate 81, that is,
On the supporting side of the second rotary body 7, a disk 85 which is in contact with the bottom wall 1a of the body 1 is rotatably supported.
It is loosely fitted into a guide piece 11 fixed to the inner surface of one side wall 1b in the width direction of the body 1, and supports the movable body 8 so as to be freely movable in the longitudinal direction of the body 1 without tilting. It is.

Further, an arm plate 12 is fixed to the base 5, and a cord 1 for energizing the heater 3 is connected to the arm plate 12.
4 and a cord-like body 15 such as a wire or chain, and each end of the cord 14 is fixed.
As shown by the chain line in FIG. As shown by the chain line in FIG. 1, it is hung on the second rotating body 7, and the other end is fixed to the other side wall 1d of the body 1 in the longitudinal direction.

Further, an application roller 2 provided in the tank 4
is rotatably supported on the tank 4 via a shaft 16, and a sprocket 17 that meshes with the chain 9 is fixed to one end of the shaft 16 with a nut 18. for,
A first upright piece 51 is provided on one side in the width direction, and the sprocket 19 is rotatably supported on this first upright piece 51, and the operating lever 10 is attached to the first upright piece 51.
Both walls 1c and 1d of the body 1 in the longitudinal direction
As shown by the chain line in FIG. 1, the intermediate portion of the chain 9 fixed to the
They are hung in an S-shape.

Therefore, by moving the lever 10 in the front-rear direction and moving the base 5 in the front-rear direction, the application roller 2 is moved to the sprocket 1.
7.

Therefore, in the embodiment shown in the drawings, in the gluing machine constructed as described above, the base 5 is formed mainly of nylon resin on one side in the width direction, and is penetrated in the front-rear direction at an intermediate position. A guide body 20 having a shaft hole is provided, and a guide shaft 21 fixed to one side wall 1c and the other side wall 1d in the longitudinal direction of the body 1 is inserted into the shaft hole of the guide body 20, and the guide shaft 21 is inserted into the shaft hole of the guide body 20. A second upright piece 52 is provided on the other side of the base 5, and this upright piece 5 supports one side of the base 5 in the width direction.
A guide body 22 such as a rotating body such as a bearing or a block body having a small coefficient of friction is attached to the movable body 8, and the lower edge of the inner strip plate 82 of the movable body 8 is bent inward to attach the guide body 22 to the movable body 8. A support piece 86 for the body 22 is provided, and the guide body 22 is supported on this support piece 86.

Therefore, support on the other side in the width direction of the base 5 can be achieved without providing a special rail.
This means that the support structure for the base 5 can be simplified.

Furthermore, since the length of the movable body 8 is approximately one-half of the length of the body 1 in the longitudinal direction, the length of the support piece 86 that supports the guide body 22 is also set so that the rails are not attached to the body 1. The weight is one-half that of the case where the movable body 8 is attached, and together with the configuration that utilizes the band-shaped plate 82 of the movable body 8, it becomes possible to reduce the weight.

Further, in the embodiment shown in the drawings, the strip plate 82
Although an inverted L-shaped holding piece 87 having a horizontal plate facing the supporting piece 86 is provided, this is for preventing the base 5 from floating and is not particularly necessary.

Further, in the drawings, reference numeral 23 denotes a long hole provided in the other side wall 1e in the width direction of the body 1, and a long hole 23 is provided in the other side wall 1e of the body 1 in the width direction.
0 is inserted externally.

As described above, the present invention uses a moving body to support the tank with a simple structure that only requires a support piece on the moving body, so there is no need to specially provide rails on the fuselage as in the past. The number of parts can be reduced accordingly, the structure can be simplified, costs can be reduced, and the overall weight can also be reduced.
