At this time, as shown in FIGS. 9 and 10, the support shaft member 52 formed at the lower end of the second link member 50 of the lock link mechanism 46 is connected to the first link member 48 of the lock link mechanism 46. It moves from above to below within the elongated hole 53.

Then, by hand or the like, as shown in FIGS. 10 and 11, the leg frame 16 is moved from the open state (leg open state) to the closed state (as shown by arrow E in FIGS. 10 and 11). (legs closed).

As shown in FIG. 11, in the closed state (legs closed state), by releasing the operating rod member 36 held by hand, the piston rod 37 connected to the operating rod member 36 and the tip of the piston member 35 can be opened. The enlarged diameter portion 38 moves downward by the urging force of the urging member 40.

As a result, the first link member 48 and the second link member 50 of the lock link mechanism 46 rotate as shown by the arrow F in FIG. The second stopper notch 58 and the stopper rod member 54 fixed to the leg frame 16 are in a locked state, and are locked in a closed state (leg closed state).

By the way, as shown in FIG. 17, in the conventional automatic wallpaper pasting machine 200, the leg frame 206 is locked in the closed state (leg closed state) with respect to the horizontal support frame, and then the leg frame 206 is locked in the closed state (leg closed state). When released, the leg frame 206 becomes free with respect to the horizontal support frame.

As a result, the leg frame 206 ends up being opened 90 degrees due to its own weight in a pendulum motion. In this way, if the leg frame 206 suddenly changes from the closed state (leg closed state) to the open state (leg open state), there will be a strong impact when the leg frame 206 opens, causing damage to the feet, fingers, etc. There is a risk that it will become stuffy and cause damage.

For this reason, in the automatic wallpaper gluing machine 10 of the present invention, even when the leg frame 16 is unlocked from the closed state (leg closed state), the leg frame 16 is caused by its own weight. The wallpaper gluing machine main body 12 of the leg frame 16 is moved so that the leg frame 16 does not open 90 degrees due to pendulum movement and slowly changes from the closed state (legs closed state) to the open state (legs open state). The opening/closing control device 100 is provided to control opening/closing of the door.

Furthermore, it is sufficient that the opening/closing control device 100 is provided at at least one corner of the horizontal support frame 13.

Furthermore, the biasing force of the opening/closing control device 100 may be configured to be adjustable.

In this way, if the biasing force of the opening/closing control device 100 is configured to be adjustable, for example, the opening/closing control device 100 biases the leg frame 16 in the closing direction with respect to the wallpaper gluing machine main body 12. If the biasing force is large, the leg frame 16 will stop halfway in the open state, and the worker may manually move the leg frame 16 into the fully opened state (open leg state). ) must be opened to the locked position.

On the other hand, if the biasing force of the opening/closing control device 100 is configured to be adjustable, the leg frame 16 can be automatically opened to the lock position in the completely open state (leg open state) and locked. It is possible and convenient.

It is also convenient because it can be adjusted to open slowly or quickly depending on the operator's preference.

With this configuration, the automatic wallpaper pasting machine 10 of the present invention includes the opening/closing control device 100 that controls opening/closing of the leg frame 16 with respect to the horizontal support frame 13, and the opening/closing control device 100: The leg frame 16 is configured to be biased in a closing direction with respect to the horizontal support frame 13.

Therefore, the leg frame 16 is biased by the biasing force (biasing force of the biasing mechanism 118 of the opening/closing biasing mechanism 112) that biases the leg frame 16 of the opening/closing control device 100 in the direction of closing the horizontal support frame 13. Even when the lock is released from the locked state (leg closed state), the leg frame 16 does not swing 90 degrees due to its own weight, but closes slowly. The state changes from a closed state (legs closed state) to an open state (legs open state).

As a result, the leg frame 16 does not suddenly change from a closed state (leg closed state) to an open state (leg open state), and a strong impact is not generated when opening the leg frame 16. However, it is possible to provide a safe and convenient automatic wallpaper gluing machine that does not hit your feet, does not get your fingers stuck in it, and does not cause any risk of scratches.
