Description

[Detailed description of the invention] The present invention relates to a woodworking glue machine.

There are a wide variety of shapes and thicknesses of the boards to be glued with wood glue machines, and when these types of boards are mixed, it is necessary to adjust the distance between the glue rolls each time, which is troublesome and reduces work efficiency. do. To improve this, the
There is 85108';j. In this system, when the board is fed onto the applicator roll, a restraining rod is provided to stop the board above the applicator roll, and in conjunction with this, the upper applicator roll is lowered to prevent gluing. However, in this method, the plate material is stopped at a position slightly past the applicator roll, so there is a problem that some parts of the tip of the plate surface are not glued.
On the other hand, separate cylinders for rotating and raising and lowering the restraining light not only complicate the device, but also cause the problem of time loss from when the restraining rod comes into contact with the plate until it escapes.

The present invention aims to completely solve these conventional problems.

Hereinafter, an example of implementing the present invention will be described based on the accompanying drawings.

In order to raise and lower the side plates through guide grooves, an air-hydro cylinder 551 for raising and lowering each of the side plates is provided at the upper position.

Reference numeral 6 denotes an upper doctor roll, and 7 an applicator roll, which are installed in parallel between the side plates 4 and 41 via shafts 8 and 9, respectively. ) (b) direction. 1). 1)' is a dam plate to prevent glue from leaking out.

Reference numeral 12 denotes a plate material thickness detecting means, which is the doctor row/L mentioned above.
A swinging lever 14.14' is swingably supported via a shaft 15 at a central position on a bracket 13.131 protruding from the side plate 4.4' at a position in front of the /6 and applicator roll 70. At this time, touch low/v16 is installed at the lower ends of both levers 14 and 14' so as to be freely rotatable, and at the upper end of one of the levers (in the example shown, the upper end of lever 14) is provided with a touch low/v16 in the direction of doctor low/L/6. A dog 17 is mounted horizontally, and the dog 17 comes into contact with a limit switch 18 disposed on the side surface of the side plate 4 when the touch low/L' 16 is in the vertical position. The limit switch 18 is activated when the cutter roll 16 comes into contact with the plate material during gluing work, which will be described later, and the swing lever I4 is activated depending on the thickness of the plate material.

On the other hand, a lower applicator roll 19 is installed between both support legs 3.31 below the coating roll in the lower half of the support leg 3.31, and a lower applicator roll 19 is installed in parallel behind the support leg 3.31. A doctor roll 20 is provided.

On the other hand, 21 is a lower part of the upper touch row/l'16 installed between the swing levers 14 and 14', and both supporting legs 3.31 are placed so as to be on the same horizontal plane as the upper outer peripheral surface of the lower application row/19. While the upper touch roll 16 is swingably provided via a swing lever 14.141, the lower touch roller /v2 is installed between the lower touch rollers.

This is a foot switch for operating the 2id air hydro cylinder 5.5'.

The apparatus of the present invention has the above-mentioned configuration, and has the following features.

The operation will be explained based on FIG.

A shows the initial state, and when the plate material 33 is placed on the lower touch row)v21 and the start button in the control box 10 is pressed, the upper doctor row/L/6, the same coating row/I/7 and the lower coating roll are activated. 19. The same doctor row) v20 is rotated in the directions of the arrows (b) and (g), respectively, to form a glued surface on the coating row) Lt 7.19, and the foot switch 32 When stepped on, the air-hydro cylinder 5.5' is activated and the upper doctor row/I/6 attached to the side plate 4.41, the same application row) V
7 and the thickness detecting means 12 are both lowered. B shows the state at the moment when the upper touch roll I6 of the detection means 12 contacts the plate material 33 at the lower limit of descent, and the swing lever 1
4.14' arrow (/14 direction opens limit switch 18 and air-hydro cylinder 5.5'
The descent of will be stopped at that position.

When the plate material 33 is pushed in in this state, the coating row/
V 7.19, and even if you release your hand from the plate 33, the plate 33 will automatically run and glue will be applied to its upper and lower surfaces (Figure C).

D shows a state in which the rear end of the plate 33 has passed between the upper and lower touch rollers 16.21, and in this state, the swing lever 1
The limit switch 18 is closed by turning in the direction of the arrow 4.14', but only for a certain period of time determined by the timer, that is, until the plate material 33 finishes passing between the applicator rolls 7 and 19. This state is maintained until a predetermined time period has elapsed. After a certain period of time has elapsed, the air-hydro cylinder 5.5' is raised and the side plate 4.41 is raised, completing the gluing process (Figure E). Continuous work is carried out by repeating the action, and at this time the plate material 33
There is no problem even if the thickness t of the parts is different as appropriate, but when gluing is performed continuously on parts of the same thickness t, the state shown in FIG.
The fixed state is achieved by operating one of the switch buttons in the switch, so that the upper applicator roll 7, upper touch roll 16, etc. do not rise even after the plate material 33 has passed. This allows for more efficient continuous work.

The above is an example of gluing on the upper and lower surfaces of the plate material, but by applying the glue to only one of the upper and lower doctor rolls 6.19, it is possible to glue only to either the upper or lower surface of the plate material 33. You can do it like this.

In addition, in the above embodiment, the case where the gluing is performed by sequential button operations has been explained, but it is possible to initially perform free thickness processing (when the thickness of the plate material 33 to be glued varies as appropriate) or fixed thickness processing. H! (When the appropriate number of plates is 330cm thick) and by switching this switch, everything else can be done automatically. In the latter case, gluing of a certain thickness can be done in an extremely short time.

The present invention is implemented as described above and is easy to operate, and the gluing work can be carried out efficiently, contributing greatly to improved productivity. Note that the use of an air-hydro cylinder in the apparatus of the present invention is very advantageous in that the positioning of the lifting and lowering operations can be performed accurately.
