BACKGROUND OF THE INVENTION
The present invention relates to an automatic gluing machine. More particularly, the present invention relates to an improved automatic gluing machine that has a structure that facilitates cleaning and cleaning of a roller and allows an operator to work safely when cleaning the roller.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, an automatic gluing machine for gluing cloth (wallpaper) uniformly and efficiently has been known. This automatic gluing machine feeds a cloth drawn from a raw cloth cross roll by a gear or the like. It has a configuration in which it is fed to a gluing roller by a roller and, after gluing, a glued cloth is fed out via a leveling roller and gluing.
[0003]
Hereinafter, a schematic configuration of a conventional automatic wallpaper pasting machine will be described with reference to FIG.
The automatic gluing machine has a measuring roller 1, a feed roller 2, a high tension roller 3, a doctor roller 4, a gluing roller 5, a gluing roller 6, a presser roller 7 and a tearing roller 8 from the side where the cloth is inserted. Has been.
[0004]
The cloth to be glued is squeezed by two rubber rollers, a measuring roller 1 and a feeding roller 2, and fed into the gluing machine body.
The measuring roller 1 is supported by bearing members on both sides, and can rotate freely. Further, since this roller is pressed against the surface of the cloth by a spring, the roller rotates in the cloth feeding direction in accordance with the cloth feeding.
[0005]
By setting the outer diameter of the roller to a constant value, if the amount of rotation of the roller is measured with a sensor, the distance that one point on the outer circumference of the roller has moved on the circumference, that is, the length of the fed cloth is obtained. Can do.
[0006]
This information is always displayed on the operation unit, and the operator can work while watching the situation. When the cross length reaches a preset length, the machine automatically stops.
[0007]
After the machine is stopped, the operator runs the blade of the cutter knife along the cutter guide 10 to cut the cloth and obtain a glued cloth having a desired length.
The glue is stored in the glue box 9 provided at the lower part of the main body, and the glue in the glue box 9 is transferred to the glue roller 5 by the glue upper roller 6.
[0008]
By adjusting the distance between the doctor roller 4 and the gluing roller 5, the thickness of the gluing adhered to the outer periphery of the gluing roller 5 is adjusted.
A layer of glue with a controlled thickness contacts the cloth and transfers the glue to the back of the cloth. The cloth obtained by leveling the glue transferred by the glue roller 8 to a certain thickness is sent out from the entire surface of the main body.
[0009]
Such an automatic gluing machine is extremely useful in that it saves the work of gluing on the cloth and enables uniform gluing. However, in an automatic gluing machine that performs gluing of adhesive glue, it is necessary to remove the glue adhering to various rollers etc. after the work is completed or when the kind of glue is changed. Therefore, cleaning and cleaning for that purpose are indispensable.
[0010]
[Problems to be solved by the invention]
The conventional automatic gluing machine has a structure in which the feed roller 2 and the doctor roller 4 are substantially horizontally opposed, and the distance between the two rollers is usually narrower than the finger width of the hand. The automatic gluing machine cleaning method is generally used by stopping the machine and keeping the rollers from rotating, but in practice, the machine is operated at a low speed and the rollers are rotated while water is supplied. There is also a frequent method of cleaning by putting the included sponge on the roller surface. At this time, if a finger is squeezed between the feed roller 2 and the doctor roller 4, the fingers are caught in the opposite direction and cause an accident.
[0011]
In order to solve this problem and further improve the safety, as shown in FIG. 6, the shaft of the feed roller 2 is supported by a bearing member, and this bearing member is fitted into the groove portion 2a provided in the frame. There has been proposed a method in which, when a finger or the like is sandwiched between both rollers by tilting in the direction in which the roller gap becomes wider, the roller itself is also retracted upward along with the disengagement of the gear mesh.
[0012]
However, in the case of this method, not all of the force for entraining the finger acts as a moving force of the roller, but only a part of the force acts.
That is, as shown in FIG. 6, when the horizontal / vertical force is decomposed in the tilt direction of the bearing member, only the component parallel to the tilt direction acts on the roller movement, so that the vertical component conversely inhibits the movement. Act on. Also, as the psychology of the operator, since the finger is reflexively pulled out at the moment when the finger is pinched, even if the operator tries to pull out the finger straight, only a part of the force acts in the direction in which the roller is detached. .
[0013]
Therefore, when the finger is rubbed, the drive gear or the roller itself can be removed to prevent an accident, but the roller removal efficiency is poor, and the operator's finger is somewhat painful. . Therefore, there is a demand for a highly safe device that increases the separation efficiency of the roller and moves the roller with less force.
[0014]
The present invention eliminates the drawbacks of the conventional automatic gluing machine described above, and provides a new automatic gluing machine that is not only easy to clean and wash, but also ensures the safety of workers. It is aimed.
[0015]
