Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a removal treatment device for removing pongee powder from a desired surface of a workpiece coated with pongee powder, such as pine tree before consolidation treatment.

For example, in order to form a rudder layer on metal products, ceramics, etc., the coating is applied to the treated material, dried, and then sintered.

Incidentally, in order to express a pattern by exposing a substrate of a desired shape on the surface of the object to be treated, it may be necessary to remove pongee from a portion of the surface. Conventionally, this was done manually by applying a ruler to the cross section of the surface to be removed and wiping the cross section with a cloth after drying the cross section and before sintering, which was extremely inefficient. In addition, it is difficult to create a complicated removal pattern and requires skill. The purpose of the present invention is to eliminate the above-mentioned inefficient work and automate the work of removing sleeve medicine.
A linear reciprocating device is provided with a brush protruding in a direction perpendicular to the traveling direction of the device, and the surface of the workpiece coated with a pure chemical such as Matsugo before consolidation treatment is placed at the bottom of the brush travel path. A mask is provided so as to be openable and closable, and the brush is brought into contact with the periphery of a through-hole formed in the mask. is removed by the brush.

An embodiment of the invention will be described with reference to the accompanying drawings. 1 is a device stand, and on the stand two rails 2 having a triangular cross section are installed.
, 2 are laid in the left and right direction.

On the rails 2, 2, two pairs of idle rollers 4, 4 in the front and rear, each having a V-shaped groove, which are attached to the lower surface of the base plate 3 of the truck 5, are used to mount the truck 5. The cart 5 supports a reversible motor 9 in the longitudinal direction on the upper part of a frame 6 erected at the rear of the board 3, and as shown in FIG. Large and small sprockets 10,
11 is fixed and supported on the lower inner surface of the frame 6, and the left sprocket 13 and the large sprocket.

Pass the chain 12 around the butt 10, and connect the right sprocket 15 and the small sprocket. ket 11 and chain 14
across. Also, on the front of the frame S, there is a ``reversible motor 9''.
A frame plate 7 is protruded from a position directly below the frame plate 7, and its edge is bent downward to form a support plate 8, which is connected to the front green of the board 3.A rotation shaft 16 is connected to the front surface of the frame 6 from the sprocket 15. The support plate 8 also supports the ends of the pulley 17, and a pulley 17 is fixed to the rotation shaft 16. 18 to tighten the rope.Furthermore, a rotation shaft 20 is projected from the sprocket 13 to the front of the support plate 8.The part protruding from the support plate 8 is made of a material such as nylon or horse hair. A cylindrical brush 21 consisting of
,, LS2 are provided, and engaging pieces 23a and 23b (see FIG. 3) are supported at the center of the lower surface of the substrate 3. The engaging pieces 23a, 23b have a cylindrical shape, and extend from a holding piece 24 provided on the lower surface of the substrate 3 to left and right screw holes 25, 25 protruding from the holding pieces 24 provided on the lower surface of the substrate 3 at positions corresponding to the front and back of the detectors LS, LS2. By screwing and rotating along the screw thread 25, the positions of the end surfaces of the engaging pieces 23a, 23b that support the detectors LS, LS2 can be arbitrarily changed in the left-right direction. Therefore, it is possible to adjust the reciprocating stroke during the reciprocating operation of the trolley 5, which will be described later. So,
The truck 5, the rails 2, 2, and the wire rope 18 constitute a linear reciprocating device provided with a brush 21.

Reference numeral 30 denotes a mask having a semi-cylindrical shape or the like provided at the lower part of the travel path of the brush 21 and covering the processed material a from above,
A through hole 31 is bored in its upper surface, with the surrounding green being a ruler green 31a having a desired pattern shape.

The green color on the rear side of the mask 30 corresponds to the frame 3 at the front of the device stand 1.
A rotary wheel 3 supported by left and right shaft support plates 35a, 35a erected on the rail 6 and stretched parallel to the rail 2.
Sekiguchi 36 connects to 5 and discharges the removed pongee medicine on the frame 36
Make sure to cover a. A rod of an air cylinder 32 is connected to an end of the rotation shaft 35. For this reason, the expansion of the rod of the air cylinder 32 causes the mask 3 to be opened around the rotation axis 35 as shown in FIG. 2, and the contraction of the rod causes the mask 3 to open as shown in FIGS.
The locking green 30a protruding from the lower rear of the vehicle 0 is placed on the frame 36 to bring the door into a closed state. In this closed state, the frame 3
The holding position of the workpiece a is determined so that the ruler green 31a of the through hole 31 comes into contact with the pongee-removed side of the workpiece a, which was placed on the surface of the workpiece A.

Further, as the brush 21 moves, the ruler edge 31
The degree of protrusion is determined so as to simulate sliding a.Furthermore, a tongue piece 33 and a tongue piece 34 are respectively formed on the side surface of the mask 30, and when the mask 30 is in the closed state, a proximal portion attached to the upper part of the shaft support plate 35a is set. The tongue piece 33 is made to face the switch SW, and the tongue piece 34 is made to face the proximity switch SW2 mounted on the frame 36 when the mask 30 is open.The operation of the above embodiment will be explained. .Before sintering, the object to be treated (a) coated with pongee, such as porphyry coral, is laid down on the frame 36 at the front of the machine stand 1 with the side from which the pongee will be removed facing upward, and the starting switch (Fig. (not shown) is turned on by manual operation, the direction of air supply to the air cylinder 32 is switched, the rod contracts, and the mask 30 becomes closed as shown in FIGS. 1 and 2, and the green ruler 31a of the through hole 31 comes into contact with the desired surface of the workpiece a, and the reversible motor 9 is driven, and the rotation of the sprockets 10 and 11 fixed to its output shaft is caused by chains 12 and 14 to rotate the sprockets 13 and 11.
15, the sprocket 15 and the pulley 17 rotate the pulley 17, which causes the winding action of the wire rope 18, causing the truck 5 to move forward, and the sprocket 13 and the rotating shaft 20 to rotate as well. brush 2
1 rotates.

Therefore, the brush 21 rubs the ruler edge 31a of the through hole 31 while rotating at the position where the mask 30 is located. So,
The dried pongee medicine on the surface of the object a facing through the through hole 31 before the solidification process is removed and discharged from the closed opening 36a. When the cart 5 moves further forward and the front surface of the engagement piece 23a on the back side of the board 3 comes into contact with the sensing piece of the detector LS2, the reversible motor 9
The direction of rotation of the dolly 5 is changed and the brush 21 is reversed, and the ruler edge 31a of the through hole 31 of the mask 30 is rotated again.
is rubbed by the brush 21, and the pure chemical exposed from the through hole 31 is almost completely removed, leaving a substrate b having a sharp boundary line along the ruler green 31a on the surface of the object a, as shown in FIG. appear. When the trolley 5 further moves backward and the rear surface of the engaging piece 23b on the back of the board 3 hits the sensing piece of the detector, the drive of the reversible motor 9 is stopped and air is supplied to the air cylinder 32. The direction is switched, the rod is extended, the mask 30 is rotated, and the door is opened as shown by the chain line in FIG. In this state, the worker removes the workpiece a, places the unprocessed workpiece a on the frame 36, turns on the start switch again, and repeats the above steps.
Instead of using the detectors LS, 2, the stop may be controlled by a timer or the like activated by the start switch. In this operation process, the proximity switch SW senses the proximity of the tongue piece 33 to confirm that the mask 30 is closed, and the proximity switch SW2 senses the proximity of the tongue piece 34 to confirm that the mask 30 is open. It is a thing,
Air cylinder 32 when the start switch is turned on
In the event that any trouble occurs to the air sliding door and it is not closed, the above-mentioned operation can be repeated extremely safely by preventing the cart 5 from running.

As described in detail above, the present invention includes a mask 30 that is openable and closable at the bottom of the travel path of the brush 21 protruding from a linear reciprocating device, and a desired pattern-shaped through-hole 3 formed in the mask 30.
1, and a through hole 3 is drilled for each reciprocation of the linear reciprocating device.
The pongee agent on the surface of the object a exposed from 1 was removed by the brush so that the substrate b having a sharp boundary line along the ruler green 31a appeared on the surface of the object a. Automation of sleeve medicine removal work can be achieved,
Moreover, there are excellent effects such as the ability to arbitrarily determine the shape of the through holes 31 to produce a desired pattern of the base material b on the object to be processed a.
