Abstract

PURPOSE:To apply solid wax on a surface to be buffed with uniformity of high accuracy and good workability by providing a vertically movable receiving tray in the lower part of a plate provided with a horizontally long rectangular hole and imposing solid wax having a rectangular section or plural pieces of rod-shaped solid wax on the receiving tray. CONSTITUTION:A plate material C is carried onto a front stand 71 and while buffing rollers 8, 8 are kept rotated by starting the motor of a buffing machine B, the buffing machine B is transferred onto the plate material C beyond the front surface plate 1 of a wax supplying device A. This machine is thereafter reset onto a rear stand 72 beyond the wax supplying device A. The traveling speed of the buffing machine B is set lower than the rotating circumferential speed of the buffing rolls 8. The contact surfaces of the buffing rollers 8 and the solid wax 4 rub against each other when the rollers pass on the front surface of the wax. The solid wax is thereby stuck to the outside surfaces of the buffing rollers 8 and the surface of the plate material C is rubbed by the rollers stuck with the wax and, therefore, the surface of the plate material is finished by buffing. The stability of the state of supporting the solid wax is assured in this way.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a wax coating device used when polishing or grinding a plate material.

(Prior Art) Metal plates, plastic plates, wooden plates, and the like are sometimes subjected to buffing for final polishing or pretreatment such as plating or painting.

To perform buffing, it is necessary to apply an abrasive to the surface to be treated, and then polish the applied surface with a flexible puff.
Conventionally, a method of applying liquid wax using a spray, a roll coater, a flow coater, etc. has been used to apply the abrasive.

By the way, in the present applicant, as a method for manufacturing an antistatic plastic plate, conductive transparent synthetic resin paint (containing antimony-containing tin oxide, conductive fine powder with a particle size of 0.2 μm or less) is added to the solid content of the paint. We have already proposed a method of applying a transparent synthetic resin paint (containing a transparent synthetic resin paint at a ratio of ~70%) to a transparent plastic plate and then puff-finishing the surface (Japanese Patent No. 1,486,042).

The antistatic plastic plate obtained by this manufacturing method has superior total light transmittance and haze value compared to an antistatic plastic plate without a puff finish.

(Problem to be solved) In this manufacturing method, buffing greatly affects the transparency of the product, and increasing the transparency requires more than the usual puffing process for pre-treatments such as polishing, plating, and painting. uniformity is required.

However, when liquid wax is used to apply an abrasive to the surface to be treated, the oil content of the liquid wax sticks to the product, and this sticking tends to impede the uniformity of puffing. Therefore,
In the puff finishing in the above method for producing an antistatic transparent plastic plate, it is not appropriate to use liquid wax as the abrasive, and it is advantageous to use solid wax. When applying this solid wax, it is advantageous to use a roller from the viewpoint of workability.

In order to apply solid wax with a roller, it is necessary to bring the roller into contact with fixed solid wax so that the wax adheres to the surface of the roller, and to bring the wax adhesion roller into contact with the surface to be coated. In this case, the fixed solid wax is rubbed off by a roller, and at this time, the solid wax receives a frictional force, and a reaction force to that force is generated at the fixed part of the solid wax, which causes the solid wax to have a physical property that makes it relatively easy to flow. As a result, there is a risk that the solid wax will flow at the fixed location, making the solid wax fixed state unstable, which may make uniform application difficult. Also, unlike liquid wax, solid wax cannot be homogenized by stirring, and if there is a seam in the solid wax, the amount of adhesion to the roller will be small between this seam and other parts. However, it is different, so
Strictly speaking, such seams of solid wax also cause uneven application.

However, in the method for manufacturing the antistatic plastic plate described above, as described above, high precision uniformity is required in wax application, and as long as solid wax is used, the fixed state of the solid wax and the alignment of the solid wax are very important. The above-mentioned non-uniformity caused by eyes and the like is minute and cannot be ignored.

An object of the present invention is to provide a wax application device that can apply solid wax to a surface to be puffed with high precision and uniformity and with good workability.

(Means for Solving the Problems) 1-The wax applicator according to the invention is provided with a vertically movable saucer at the bottom of a plate in which a horizontally long thick rectangular hole is provided, and in which the saucer has the shape of the hole described above. A wax supply device is provided, in which a solid wax having a rectangular cross section corresponding to the above plate or a plurality of rod-shaped solid waxes arranged in a horizontal direction is placed, and the upper end of the solid wax is placed in the above hole, and the upper end of the solid wax is placed in the above hole. This structure is characterized by comprising a buff roller that moves back and forth.

(Explanation of Examples) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an example of a wax supply device used in the present invention, and FIG. 2 is a sectional view taken along the line ■--■ in FIG.

In FIGS. 1 and 2, 10 is a horizontally long box, and a horizontally long rectangular hole 2 is provided in a plate 1 of the earthen wall. Reference numeral 3 denotes an elongated saucer provided within the box 1, with protrusions 31 and 31 provided at both ends. 4 is a solid wax having a rectangular cross section placed on the saucer 3, the lower end of which is fitted between the protrusions 31, 31 of the saucer 3, and the upper end of which is projected from the hole 2 of the plate 1.

The saucer 3 is supported so as to be movable up and down. In the illustrated embodiment, as shown in FIG. 3, bevel gear 51. ...
The rotating horizontal shaft 52 with the rotary horizontal shaft 52 attached thereto is pivotally supported below the box 10, the bevel gear 54 at the lower end of the rotating vertical shaft 53 meshes with the bevel gear 51 of the rotating horizontal shaft 52, and the threaded bracket 55
A rotary slider 57 is attached to the upper end of the vertically movable shaft 56 screwed into the
The lower end of the vertically movable shaft 56 and the upper end of the rotating vertical shaft 53 are connected to a square hole 551.
and a square rod 531 so that they can be slid up and down. Therefore, when the horizontal axis of rotation 52 is rotated, the rotation is transmitted to the vertical axis of rotation 53 by the bevel gears 51 and 54, and as the vertical axis of rotation 53 rotates, the vertically movable axis 56 is rotated and the threaded bracket It is sent upward or downward for screw engagement with 55, and the saucer 3 is raised and lowered along with this upward and downward transport.

FIG. 4 is an explanatory diagram showing one embodiment of the present invention.

In FIG. 4, A is the wax supply device described above. Reference numeral 71 is a front mount, and 72 is a rear mount, and a wax supply bag MA is disposed between these mounts 71 and 72. B is a puff machine equipped with two sets of polishing rolls 8.8 which are moved by an electric motor (not shown). This roll 8 is made of urethane foam or other relatively soft material. This puff machine B is suspended from a rail installed above and is driven by an electric motor, but the mechanism thereof is not shown.

In order to puff-finish the surface of a plate using the above device, as shown in FIG.
Next, the buff roller 8 is activated by starting the electric motor of the puff machine B.
, 8, the puff machine B is moved over the top plate 1 of the wax supply device A and onto the plate C, and then is returned over the wax supply device A and onto the rear pedestal 72.

However, the running speed of the puff machine B is set to be low compared to the rotational circumferential speed of the buff roller 8, and when the buff roller 8 passes over the upper surface of the solid wax 4, the contact surfaces thereof rub against each other, and the solid wax is transferred to the buff roller 8. The wax adheres to the outer surface and the surface of the plate C is rubbed by this wax adhering roller, so that the surface of the plate C is puff-finished.

In the above, compared to the rotation speed of the buff roll 8 when the puff machine B passes over the upper surface of the solid wax 4, the rotation speed of the buff roll 8 when the puff machine B is positioned on the plate material C and puffing is being performed. It is desirable to make it fast. For example, it is desirable to provide a limit switch between the wax supply bag [A and the front frame 71, and to switch the rotational speed of the buff roll 8 by contacting the limit switch of the puff machine B.

The running direction of the puff machine B is normally switched by a limit switch.

FIG. 5(r) shows the state in which the solid wax 4 is exposed to the plate l. As shown in FIG. 5 (II), each time the buff roll 8 passes over the top surface of the solid wax 4, the top surface of the rod-shaped solid wax 4 is scraped off by the buff roll 8, and the amount of wax 4 that protrudes from the top is reduced. gradually decreases, and the upper surface of the solid wax 4 comes close to the upper surface of the plate 1, as shown in FIG. This operation can be performed manually, but is preferably automated. For this automation, for example, every time a limit switch for reversing the running direction of the puff machine B is activated, the horizontal shaft 52
The saucer 3 can be raised by rotating it by a predetermined amount.

In FIG. 5 (II) above, the force acting on the top surface of the solid wax 4 due to friction with the buff roll 8 is F, the height from the hole 2 position of the plate 1 to the top surface of the solid wax 4 is The height to the hole 2 position of plate 1 is L
Then, the horizontal force f□ acting between the lower end of the solid wax 4 and the saucer 3 is f1=FI/L, and L
>I, the f-factor can be kept extremely small.

Further, the force f2 that the solid wax 4 receives from the hole edge a of the plate 1 is f2=F(I/L+1), which is equal to F and significantly larger than the above f1.

If the solid wax 4 is continuously subjected to such a large force f2 at the same location for a long period of time, significant weakening of the wax at that location is unavoidable, but in the present invention, as described above, the solid wax 4 is raised at predetermined intervals, and the position of the solid wax 4 in contact with the hole a of the plate 1 is changed at a predetermined interval, so that the solid wax has sufficient time to contact the hole edge a of the plate 1 at the same position. It can be shortened,
The above-mentioned settling of the solid wax 4 can be suppressed to a slight degree.

In this way, the plate hole 11a in the solid wax 4
It can effectively prevent fatigue at the point of contact with the
1 can be made extremely small and the lower end of the solid wax can be effectively prevented from slipping on the receiving tray 3, so that the stability of the supporting state of the solid wax can be guaranteed.

FIG. 6 is a side view showing another embodiment of the present invention.

In FIG. 6, parts with the same reference numerals as those in FIG. 4 indicate members or devices having the same configuration as those in FIG. 4.

In FIG. 6, B is a puff machine, 8, 8 is a buff roll, A is a wax supply device, 4 is a solid wax, 71
72 indicates the front frame, 72 indicates the rear frame, and C indicates the plate material. 6 and 6 are wheels attached to the wax supply device A, and 60 and 60 are rails laid between the front mount 71 and the rear mount 72 in a direction perpendicular to the running direction of the puff machine B; The rail 60,6
0 so that it can reciprocate in the lateral direction (direction perpendicular to the running direction of the puff machine B).

In the wax applicator of this embodiment, by shifting the period of reciprocating movement of the puff machine B and the period of reciprocating movement of the wax supply device A along the rail 60, 60, each time the upper surface of the solid wax contacts the buff roll. , the contact state can be phase-shifted in the lateral direction, and even if the solid wax is somewhat non-uniform, the non-uniformity can be leveled out to achieve sufficiently homogeneous application.

In this embodiment, as shown in FIG. 7, a large number of rod-shaped solid waxes 40. This is particularly useful when used in horizontal alignment. Multiple rod-shaped solid wax 40. ..., when used in a horizontally arranged manner, the amount of wax adhered to the buff roll 8 differs even if slightly between the seams 41 between the solid wax rods and other parts, resulting in high precision. However, according to this embodiment, uniform application becomes possible.

(Effects of the Invention) The wax applicator according to the present invention has the configuration described above, and is capable of applying solid wax to the surface to be treated sufficiently without any omission.
Can be applied in various ways. Therefore, the solid wax can be applied to the surface to be puffed with excellent efficiency and in a sufficient manner, and the puff finishing in the above-mentioned method for manufacturing an antistatic transparent plastic plate can be performed without inconveniences such as oil sticking when using liquid wax. The process can be carried out with excellent work efficiency and with sufficient uniformity. Also, insert solid wax into the hole in the plate,
Since the solid wax is supported by a simple means in which the lower end is supported by a vertically movable saucer, the wax supply device can be simplified.
