BACKGROUND OF THE INVENTION 1. Field of the Invention This invention removes projections such as concrete pieces and burrs adhered to the surface of plywood for concrete formwork and other plate materials used in civil engineering and construction work, and recycles them. The present invention relates to a device for removing projections on the surface of a plate material for use.

2. Description of the Related Art Plywood for concrete formwork used in civil engineering and construction work is used to support and harden concrete poured into a concrete wall or foundation of a building. As shown in FIG. 17, since a piece of concrete adheres to the surface of the plywood after use and it cannot be reused again, it is basically disposable. After use, they were either discarded as they were or burned as fuel. Such concrete formwork plywood used for civil engineering and construction is manufactured by processing trees that have undergone considerable annual rings, but the amount used and the number of tree species are mostly in tropical forests such as Southeast Asia. It is an imported material from the area that owns it. In recent years, deforestation due to timber cutting has progressed on a global scale, but deforestation has spurred air pollution on the earth even further, and carbon dioxide emitted in large quantities due to the rapid increase in the use of fossil fuels due to the development of industrial technology. It is said that it also reduces the absorption capacity of the earth and promotes global warming.

[0003]

The plywood for concrete formwork as described above may be used repeatedly 2-3 times, but even when it is reused, a long spatula-like metal spatula is used at the tip of the long rod. It is usual that a worker attaches a remover and manually removes the concrete pieces one by one, and the efficiency of the removing work is extremely low at present. As described above, the work of removing the concrete pieces attached to the surface of the plywood relies on human work, and since it cannot be processed in a large amount in a short period of time, it was hardly reused on a large scale. The present invention has been made in view of the above problems, and an object thereof is to provide projections such as concrete pieces adhered to the surface of a plate material such as plywood for concrete formwork used in civil engineering and construction work. An object of the present invention is to provide a device for removing projections on the surface of a plate material, which removes objects and makes them usable again.

It is composed of a coating roller 8 for coating the agent. A dust collecting duct 9 is arranged around the cleaning brush 7. 9 in FIG.
Reference numerals a and 9a are the dust collecting ports. 10 is the coating roll
It is a tank for the release agent to be supplied to LA 8.

Reference numeral 11 shown in FIGS. 1 to 3 is a handle for adjusting the thickness of the processing plate W, and jacks 13 and 14 arranged on the left and right sides of the rotary shaft 12 are moved up and down to move the jack 13 and the like. The plate 15 attached to the upper part and the feed roller 3 and the like arranged on the plate 15 are moved up and down. Reference numeral 16 is a mechanical digital device for setting the thickness of the processing plate material W.

Reference numerals 17 and 18 shown in FIG. 3 denote the side rims.
It is a motor for driving the bar 5 and is attached to the left and right. Details of the side rim bar 5 will be described later. Also, 19
Is a motor for driving the top rim bar 6. The details of the top rim bar 6 will be described later.

FIG. 4 is a plan view of the portion to which the side rim bar 5 is attached, FIG. 5 is a part of the view taken along the arrow Q in FIG. 4, and FIG. 6 is a view taken along the arrow R in FIG. That is, the plates 20 and 21 are fixed to the side frames 1 and 2, respectively, and further, the slide bars 22 and 23 and the male screw rod 24 are installed on the plates 20 and 21. Reference numerals 27 and 28 denote slide plates for adjusting to the width of the plate material W for processing. In particular, the slide plate 28 is movable in a lateral direction (a direction perpendicular to the material feeding direction) as described later. . The slide bars 22 and 23 and the male screw rod 24 are installed so as to pass through the slide plates 27 and 28. The slide bushes 2 are attached to the slide plates 27 and 28.
5 and 26 are fixed to the slide bars 22 and 2 respectively.
It is made slidable by penetrating 3. In addition, plate 2
A coil spring 36 is arranged between 0 and the slide push 25. Thus, when the slide plate 27 comes into contact with the pin 53a of the chain 53 described later, the coil spring 36 mounted between the slide bush 25 and the plate 20 makes the slide plate 27 flexible so as to follow the side surface of the processing plate material W. To slide. Further, a plate 29 having a female screw holder 31 fixed thereon is fixed to the other slide plate 28. A female screw 30 is fitted in the female screw holder 31, is made unrotatable by a key 32, and a coil spring 37 is arranged between the female screw 30 and the plate 29. Further, the male screw rod 24 is screwed onto the female screw 30. In this way, the other slide plate 28 also flexibly slides along the side surface of the plate material by the coil spring 37 when the processing plate material W comes into contact with the pin 53a of the chain 53 described later.

As can be seen from FIG. 5, the side rim bar 5 is a motor 18 fixed to the slide plate 28.
And a sprocket 51 fitted to the shaft 18a of the motor
A sprocket 52 rotatably pivotally mounted on a shaft 33 fixed to the slide plate 28, and a chain 53 wound around these sprockets 51 and 52 (slide plate). -The same applies to the side rim bar 5 of To 27). The chain 53 has a long pin 53a on one side.
The pin 53a also functions as a shaft pivotally connecting the link. Then, the side surface of the processing plate W is slid on the longer side of the pin 53a to scrape off protrusions such as concrete pieces attached to the side surface.
In this case, when the chain 53 descends, the scraping action becomes smooth if the whole chain is slightly tilted so that the pin 53a contacts the side surface of the plate material and does not contact when rising.

Since the width of the plate W for processing is not constant, the left and right positions of the chain 53 must be changed each time the side is processed. Then, by rotating the handle 34, the male screw rod 24 is rotated to move the slide plate 28 (plate 29) in the width direction, but the moving distance at that time is the mechanical digital 3 screwed to the male screw rod 24.
I read it in 5. In this way, the width of the processing plate material W is determined and the side surface is deburred. And, as described above, the tip of the pin 53a of the chain 53 has the working plate material W.
When the slide plates 27 and 28 are brought into contact with the side surface of the plate, the coil springs 36 and 37 flexibly elastically displace the tip of the pin 53a to follow the side surface of the processing plate W.
Numerals 38 and 39 shown in FIGS. 5 and 6 are copying rollers, which are the metal fitting 40, the metal fitting 41 having a long hole and the bolt 42, and the tip of the pin 53a of the chain 53 and the side surface of the processing plate W. I made a fine adjustment between

FIG. 7 is a plan view of the vicinity of the top rim bar 6, and FIG. 8 is a view taken in the direction of arrow S in FIG. In these figures, 61a, 61b, and 61c are cranks and the motor 1
The crank bars 62a, 62b, and 62c are fitted in the crank 61a and the like so as to be relatively rotatable. And these crank bars 62a
Mounting bars 63a, 63b, and 63c are fixed to these parts.

A plate W for processing is attached to the mounting bar 63a and the like.
The removal bar 65 having a large number of parallel pins 64, which are scraping blade tools for removing projections such as concrete pieces attached to the surface of the above, is replaceably fixed. Reference numeral 66 is a reinforcing bar fixed to the mounting bar 63a or the like for mounting the removal bar 65. Thus, the top rim bar 6 is composed of a reciprocating mounting bar 63a and the like, a plurality of parallel pins 64 planted in the removing bar 65, and a driving device for the mounting bar 63a and the like. When the motor 19 is driven, the crank 61
a and the like rotate as shown in FIG. 8 and the mounting bar 63a
The parallel pins 64 implanted in the removing bar 65 remove the projections such as concrete pieces on the surface of the processing plate W while moving in parallel as indicated by arrows. If the front surface of the processing plate W is removed, the back surface can be scraped off if necessary. Reference numeral 70 is a spring for allowing the mounting bar 63a and the like to move up and down flexibly along the upper surface of the processing plate material during processing.

Next, a modification of the top rim bar 6 will be described. 9 to 12 are views showing modified examples of the top rim bar 6 constituting the present invention. 9 is a plan view of the top rim-bar 6 portion, FIG. 10 is a view taken in the direction of arrow T in FIG. 9, and FIG.
Is an enlarged detail view of FIG. 10, and FIG. 12 is a sectional view taken along the line AA of FIG.

Reference numeral 71 denotes a fixed plate which is erected between the two side frames 1 and 2. A sprocket 73 is attached to one of the lower surfaces and a plate 72 is attached to the other lower surface.
Is fixed and a drive motor 74 is attached to the plate. A sprocket 75 is fitted on the drive shaft of the drive motor 74. And the sprocket 73
76 between the drive motor and the sprocket 75 of the drive motor.
Is wrapped around. That is, the chain 76 is driven so as to move laterally in the direction perpendicular to the material feeding direction. A housing plate 77 is fixed to the lower surface of the fixed plate 71, a cushion material 78 such as sponge is fitted inside, and a ribbon steel thin plate 79 is fixed so as to press the cushion material 78 from above. Has been done.

FIG. 12 shows details of the mounting state of the chain 76. As shown in this figure, like the chain 53 of the side rim bar 5, one of the pins 76a of the chain 76 is elongated. In this way, the chain 76 moves the lower surface of the fixed plate 71. In this case, when the pin 76a of the chain 76 comes into contact with the surface of the plate material W for processing, the cushion material is made through the thin plate 79 made of ribbon steel. Since it moves while giving an elastic displacement to 78, it is possible to scrape only the concrete pieces adhering to the surface of the working plate W without forcing it. In addition, the upper surface of the workpiece W is pin 76.
As a countermeasure when the height is higher than the lower end of a by h, an elastic supporting device such as an air cylinder is provided between the fixed plate 71 and the side frames 1 and 2, and the pin 76a is provided.
When the workpiece W touches the workpiece W, it may be flexibly displaced upward. Reference numeral 80 denotes a mounting plate for mounting the housing plate 77. The housing plate 77 is attached to the fixed plate 71 through the mounting plate 80 so that the housing plate 77 has rigidity and the housing plate 77 is rigid. A space for arranging the cushion material 78 and the thin plate 79 and for moving the chain 76 is formed in the throat 77. Further, the pins 76a of the chain 76 are connected to the housing plate 7
It is moved so as to protrude from the groove 77a formed in 7.

If the modification of the top rim bar 6 is constructed as described above, when the chain 76 is driven by the motor 74 and the processing plate material W is fed to the chain 76, the chain 7 is formed.
Since the pin 76a of 6 is elastically displaced by the cushion material 78, the pin 76a of the chain 76 can scrape off only the concrete piece on the surface without damaging the surface of the plate material. Further, the side rim bar 5 also drives the chain 53 in which the long pin 53a is planted, so that the concrete piece on the side surface can be scraped in the same manner.

Next, the cleaning brush 7 shown in FIG. 1 is for cleaning the surface of the plate material from which the concrete pieces adhered by the parallel pins 53a and the parallel pins 64 of the chain 53 are removed. And as shown in FIG.
Driven by 3. Although the cleaning brush 7 is used as the cleaning tool in this embodiment, a fluffy flap may be used instead of the cleaning brush 7. Then, the removed concrete pieces are sucked and removed by the dust collecting duct 9. In addition, the release agent coating roll
The la 8 is for applying a release agent to the surface of the processing plate material W removed by the cleaning brush 7 as needed. The release agent application roller 8 is sponge-like. I used the one soaked with the release agent. The release agent coating roller 8 is always supplied with the release agent from the tank 10 for coating.

The apparatus for removing projections on the surface of a plate according to the present invention has the above-mentioned structure. Next, its operation will be described. First, the processing plate material W conveyed by the conveying mechanism such as the feed rollers 3 and 3 is held by the pinch roller 4 and the like while being held by the side rim bar (the vertically moving chain and the planted in the chain). Scraping tool for removing projections attached to the side surface of a plate material for processing, which comprises a pin and a drive device for driving the chain, or a rotating sprocket around which the chain is wound or a disk which rotates integrally with the sprocket. Both side surfaces to which the concrete pieces are attached are scraped off by the implanted pins) 5. Further, the working plate material W is a scraper for removing projections attached to the upper surface of the working plate material including a top rim bar (a reciprocating bar, a driving device for the bar, and a pin implanted in the bar). Tool, or a scraping tool consisting of a chain that moves laterally on the lower surface of a fixed bar, a pin that is planted in the chain, and a drive device that drives the chain. It is scraped. Then, it is cleaned by a cleaning brush 7, and a release agent is applied by a release agent application roller 8. After that, although not shown, it is adsorbed by a suction pad or the like and stacked on a predetermined place by a moving device.
When changing the width of the processing plate W, the handle 34
While driving the mechanical digital 35, the male screw rod is driven to determine the width.

Although one embodiment of the apparatus for removing projections on the surface of a plate according to the present invention is as described above, various modifications are possible. For example, in the chain 53 wound around the sprockets 51 and 52 constituting the side rim bar 5 which is the scraping tool shown in the embodiment, the pin 53a is lengthened to scrape the side surface of the plate W for processing. However, as shown in FIG. 13, the chain is an ordinary chain in which the pins are not elongated, and a disk 56 having a scraping pin 55 is fixed to the sprocket 52, and the disk 56 is rotationally driven. It is also possible to scrape off concrete pieces and the like attached to the side surface of the processing plate material W,
As shown in FIG. 14, a pin 55 may be planted in the sprocket 52 itself and driven to rotate. Alternatively, as the chains (53, 76) used for the side remover and the top remover, various modified links such as one in which one of the links is formed long or one in which the links are formed at a right angle can be used. Further, as the side remover or the top remover, as shown in FIG. 15, a spline 57 having a groove 57a and a protrusion 57b may be rotated to scrape the side surface of the processing plate W. Alternatively, as a top rim bar for scraping the surface of the processing plate W, as shown in FIG. 16, several disks 67 having a large number of pins 67a are arranged and rotated to rotate the concrete adhered to the surface. You may make it scrape off protrusions, such as a toe piece. Of course, the surface of the processing plate W may be scraped off by rotating the spline 57. As the side rim bar 5, a removal bar 6 in which a large number of parallel pins are planted like the top rim bar 6 is provided.
A lever-crank mechanism may be used as in No. 5, and the parallel pins may be thin and long and elastically deformable. Alternatively, a thin long pin may be formed in a brush shape and rotated to scrape off the concrete piece.

Further, the side rim bars 5 and the top rim bars 6 may be in the form of shoji grids. Furthermore, the side rim bar 5 and the top rim bar 6 are not limited to scraping devices by rotary motion and reciprocating motion,
It is also possible to scrape by vibrating, vertically moving or eccentrically moving the plate on which the parallel pins are implanted or the shaft on which the spline is formed. Further, the setting of the width of the plate material W for processing is not limited to that of the embodiment, and it may be set by moving independently on the left and right sides. As described above, various modifications can be made to the device for removing projections on the surface of a plate according to the present invention.
