2. Description of the Related Art Conventionally, in the pasting work of interior cloths for buildings, in order to reduce the load of the pasting work of wallpaper and to make the pasting uniform, a manual or automatic operation is required. Gluing machines have been widely used. In particular, automatic gluing machines have become widespread as their performance has improved, and they have become indispensable for applying interior cloth.

In such an automatic gluing machine, for example, as shown in FIG. 7, a wallpaper (a) drawn from a raw roll (a) is passed through a horizontal rod-shaped stay (c) for width. It is generally known that it is supplied to a cutting device (d), cut into a predetermined width, and then pressed against the upper surface of a horizontally sizing roller (e) to be glued. There is.
And in this structure, the gluing roller (e) is
The glue is supplied from the glue container (F). In addition, in this automatic gluing machine, the gluing of the wallpaper is performed stably by the guide roll (ki). Raw roll (A)
Is a support arm attached to the frame of the automatic gluing machine.
Is also supported by.

Such an automatic gluing machine is useful for simplifying gluing work and enabling uniform gluing, but there are still some points to be improved in the conventional apparatus. It was the actual situation. A particularly important problem is that the conventional device uses a horizontal rod-shaped stay (c) for applying the required tension to the wallpaper (a), but the paper cutting device (d) The wallpaper (a) may be distorted before entering, and it is difficult to keep the right and left width trims in predetermined dimensions.

Such an inconvenience is caused by the tension stay (c) rattling due to friction with the wallpaper (a) and the tensile force when the wallpaper (a) is supplied to the width-cutting device (d). This was caused by the fact that the stay (c) fell off in some cases as it was deflected. In addition, the original roll (a) is often deformed from a circular shape to an elliptical shape during transportation, and it is difficult to unravel in this state, and it often accompanies vibration. It was also the cause of making (c) unstable.

This is because, in the conventional automatic gluing machine, the horizontal rod-shaped tensioning stay (c) has an automatic gluing machine frame or the like at both end groove portions (s) as shown in FIG. Generally, the structure is such that it is locked by inserting it into the locking piece part of (3), so the inconvenience occurs as described above in the operation of the gluing machine, and the wallpaper (a) at the preparation stage Locking piece (s) even when setting, transporting or storing
There were also inconveniences such as easier fall-off and damage.

The present invention has been made in view of the above circumstances, and has improved the drawbacks of the conventional automatic gluing machine,
A new automatic glue that can prevent distortion of the original fabric supply wallpaper, improve dimensional stability and stability of gluing operation, and eliminate inconveniences during use, transportation, etc. to further improve convenience. The purpose is to provide the equipment.

[0008]

In order to solve the above-mentioned problems, the present invention provides an automatic gluing machine for gluing by pressing a wallpaper against a gluing roller which is horizontally supported and rotates. Provides an automatic gluing machine, which is equipped with a compression spring and a spring pin, and is detachably locked to the body frame at its end.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The automatic gluing machine of the present invention will be described in more detail below with reference to the drawings. FIG. 1 is a side view showing an example of this invention. For example, in this example,
After pulling out the wallpaper (2) from the original roll (1) and cutting the left and right in a width-cutting device (3) so as to have a predetermined width, the wallpaper (2 ) Is pressed and glued to obtain the desired glued wallpaper (5), first, the wallpaper (2) is pulled out from the original roll (1) and slidable through the wallpaper tension adjusting roller (6). It is led to the tensioning stay (10), and then the wallpaper (2) is supplied to the paper trimming device (3).

In this structure, the wallpaper stay (1
0) controls the tension of the wallpaper (2) and plays a role of enabling stable wallpaper supply. And this stay (10)
Locks and locks a suitable number of one or more locking pieces (15) provided at appropriate positions of the main body frame, and the wallpaper (2) holds the wallpaper (2) through the fixed stays (10). ) To.

As the wallpapering stay (10), for example, as shown in FIG. 2, a compression spring (101) and a spring pin (102) are built in at least one end, and the main frame of an automatic gluing machine is used. In the end groove portions (103a) (103b) to be attached to the locking pieces, the spring pin (102) that is elastically slid is illustrated as a preferable example.

First, the engaging piece (15) of the main body frame is provided with a groove (103a) having a spring pin (102) built therein.
Push in the spring pin (102) from the direction of arrow A in the figure, and then insert the other groove (103
Insert b). When the fitting is finished, the spring pin (102) tries to project until it is stopped by the stopper (104) by the elastic reaction force of the compression spring (101), and the projecting spring pin (102) causes the locking piece (15) to move. ) Press firmly to firmly stay (10)
Install and fix.

The tension stay (10) with the spring pin (102) built therein may have any structure and shape. For example, as shown in FIG. 3, a long hole ( 105) and open the spring pin (1
02) through which the end of the pin (106) is slidable into the slot (105), and the spring pin (10)
2) and this pin (106) are integrated into the groove (10
3a) may be projected by an elastic reaction force, and the tensioning stay (10) may be firmly attached and fixed to the locking piece (15).

In any case, the tension stay (1) incorporating the compression spring (101) and the spring pin (102).
0), wallpaper (2) supply instability and distortion due to deflection from the horizontal state, which is unavoidable in the case of the conventional stay where only the end groove portion is provided, and further, the locking piece ( It is possible to effectively prevent the inconvenience of dropping from 15) and occurrence of trouble due to this dropping.

The object of the invention is also synergistically realized by the adjusting roller (6). That is, the adjusting roller (6) is slidable in an obliquely vertical direction along the support arm (7) of the original roll (1), and is restricted by the stopper (8) when moving upward. There is. Adjustment roller (6)
Slides up and down in accordance with the winding diameter of the original roller (1) and the pull-out tension, and plays a role of suppressing the warp in the width direction of the wallpaper together with the tension stay (10). .

FIG. 4 illustrates this adjusting roller (6). It has a required weight and has groove portions (9) at the left and right ends which are guided by the left and right pieces of the support arm (7). FIG. 5 illustrates the stopper (8) described above. Furthermore, in the example of FIG. 1, as is apparent from the enlarged view of FIG. 6, the support arm (7) of the wallpaper roll (1) is used.
Is rotatable in the direction of arrow B in the figure. That is,
Specifically, as shown in FIG. 6, the support arm (7) is rotatable in the direction of arrow B at the rotation center (11) of the main body frame, and the locking notch ( The nut (14) can be locked to the main frame of the apparatus by either of (12) and (13).

When the apparatus is used, the support arm (7) is extended and the locking notch (13) is fixed with the nut (14) as shown in FIG. 6, and the original roll (1) is supported by the support arm (7). Support. Notches (1
Fix 2) with nuts (14). In this way, the supporting arm (7) is not restricted by the presence of the supporting arm (7) during transportation and storage, and the location and space of transportation and storage are not restricted. That is, the support arm (7) is in a folded state.

With such an improvement, the convenience of the automatic gluing machine is greatly improved. Of course, the present invention is not limited to the above examples, and various details can be applied to the details of the present invention.
