Abstract

PROBLEM TO BE SOLVED: To reduce the load on a worker through a series of work by automatically carrying out a series of the works from the coating to the drying of a coating liquid such as an adhesive liquid to reduce the treatment by manual works. SOLUTION: A roller part 31b of a coating roller 31 which is impregnated with the adhesive liquid by a coating apparatus 11, is brought into elastic contact with a core metal 3 in the mid-way of the transfer of a core metal supporting frame 2 on which the core metal is set. The coating of the adhesive through the elastic sponge made roller part 31b begins with the rotation of the coating roller 31 and a coating region of the core metal 3 is uniformly coated with the adhesive liquid. Because the coating roller 31 has a vertical displacement function to be brought into elastic contact with the core metal 3 by the dead weight in the coating, the roller part 31b is pushed up while being deformed to follow the shape of the core metal 3 by the contact with the core metal 3 and is rotated together with the core metal 3 by the friction force produced between the coating region of the core metal 3 and the roller part 31.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coating / drying system for coating and drying a coating liquid on a work (for example, a blade core metal).

[0002]

2. Description of the Related Art Generally, a welder blade is formed by fixing a blade made of urethane, for example, to a metal cored bar made of a metal material at a predetermined position. In some cases, it may be necessary to apply an adhesive solution (also referred to as a primer solution).

As a method for applying such an adhesive solution, the present situation is that a large number of people apply the brush by hand. That is, as shown in FIGS. 17A to 17C, the hair 102a of the brush 102 impregnated with the adhesive liquid is brought into contact with the application surface 101a of the blade core metal 101. Then, in this state, the adhesive liquid is applied to a necessary portion by moving the application surface 101a in the longitudinal direction of the blade core metal.

[0004]

[Problems to be Solved by the Invention] Such a brush 102
In the manual coating method by
Not only 01a but also the fracture surface is coated with the adhesive liquid. As a result, the bristles 102a of the brush 102 come into contact with the burrs (burrs) of the blade core metal 101, so that the number of brushes 1 increases as the number of coating processes increases.
The bristles 102a of No. 02 are cut, and the cut portion remains on the surface of the blade core metal 101 and is mixed as a foreign matter.

The control of the film thickness of the adhesive liquid to be applied is such that the operator visually checks the applied portion while performing the brush applying operation and confirms it by the change in color of the applied portion. In this way, it is unclear whether the concentration of the adhesive liquid is stable if it is a method of dipping a small amount of the adhesive liquid into a small dish, dipping the brush, and impregnating the brush with the adhesive liquid. Is a disadvantage. Moreover, if a small amount of the adhesive liquid is dispensed to the small plate, the concentration of the adhesive liquid tends to increase because the organic solvent contained in the adhesive liquid gradually evaporates.

Further, instead of such a hand-painting method using a brush, a stamp (pressing) method using an elastic sponge pad having a size substantially corresponding to the coated surface of the core metal,
An elastic sponge fixing method in which a core metal is moved with respect to an elastic sponge pad fixed in a fixed position, a spray method in which masking is performed while leaving the application surface and spraying is possible. However, the above-mentioned stamping (pressing) method requires setting of conditions such as pressing pressure, stroke, pressing time, etc., and it is difficult to control the concentration of the adhesive liquid that appears on the roller surface. Also, the elastic sponge fixing method has unstable durability of the elastic sponge,
As in the case of brush coating, there is a risk of rubbing and inclusion of foreign matter. Further, the spray method has a problem in working environment because the adhesive liquid is scattered around. Therefore, neither is suitable for the coating process of the adhesive liquid for the blade core metal as described above.

Further, the blade core metal is stacked and placed in an oven for baking, but after the adhesive liquid is applied to the core metal, the adhesive liquid is naturally dried. If they are piled up immediately after the application process of the liquid, the traces of the piles are left and there is a problem in appearance.
Therefore, for the purpose of drying the adhesive liquid, for example, core metals are arranged at intervals on a corrugated cardboard paper, and after being dried, they are rearranged so as not to take much space when put in an oven, The burden on the operator is increasing.

According to the present invention, a series of operations from the coating process of a coating liquid such as an adhesive liquid to the drying process are automatically performed, the manual process is reduced, and the burden on the operator is reduced through the series of processes. It is intended to provide a drying system.

[0009]

According to a first aspect of the present invention, a work is set on a work support table, and while the work is conveyed together with the work support table, a coating liquid is applied to the work and a drying process is performed on the work. A coating / drying system for carrying out, wherein the work support is moved between a work setting position where the work is set on the work support and a take-out position where the work is taken out from the work support, and a shaft. Portion and a roller portion made of elastic sponge provided in the central portion of the shaft portion thereof, and a coating processing roller in which the roller portion is impregnated with a coating liquid, and a transfer path of the work support table by the transfer means. Roller support means provided for rotatably supporting the coating treatment roller so that the roller portion thereof can elastically contact the work, and the roller support. Means for supplying a coating liquid to the roller portion of the coating processing roller, and a work provided on the take-out position and coated by the coating processing roller, the work supporting base. From the work piece, and the work transfer means for transferring the work piece to the drying processing position,
Work drying processing means for supplying drying air to the work at the drying processing position is provided.

According to this structure, the work support table on which the work is set can be moved by the transfer means between the work setting position and the take-out position. During the transportation, the coating roller impregnated with the coating liquid is brought into contact with the work. At this time, the coating processing roller is rotatably supported by the roller supporting means so that the roller portion thereof can elastically contact the work, so that the coating processing roller rotates as the work is transferred, By the rotation, the coating liquid is applied to a predetermined portion of the work. The coating liquid is supplied to the coating processing roller by a coating liquid supply means to a roller portion that is in elastic contact with the work, and the roller portion is always kept impregnated with the coating liquid.

At the work take-out position, the work to which the coating liquid has been applied is removed from the work support table by the work transfer means and is transferred to the drying processing position. Then, a drying air is supplied by the drying processing means toward the work conveyed to the drying processing position, and the coating liquid is forcibly dried, whereby the work is dried.

In this way, a series of work from the coating process of the coating liquid to the drying process is automatically performed, and the manual work of the work is reduced, so that the burden on the operator is greatly increased. It will be reduced.

According to a second aspect of the present invention, the roller supporting means has a groove portion opened upward, and a supporting member for supporting the shaft portion of the coating processing roller in the groove portion so as to be displaceable upward, A support member that supports a support member, and the roller portion of the coating processing roller can elastically contact the surface of the work in a state where the shaft portion of the coating processing roller is in contact with the bottom portion of the groove portion of the support member. It is desirable to configure it as there is.

With this configuration, the shaft portion of the coating treatment roller is supported by the groove portion of the support member that is open upward so that the shaft portion of the coating treatment roller can be displaced upward. Therefore, only the upward displacement of the coating treatment roller is allowed. It Thus, the roller portion (elastic sponge) impregnated with the coating liquid is elastically contacted with the work by the application processing roller only by its own weight, and is deformed. Since the work is transferred in this elastic contact state, the coating treatment roller rotates together with the movement of the work, whereby the coating liquid is applied to the work. Therefore, due to the natural deformation of the roller portion of the coating processing roller,
Since the coating process is performed, the structure is more advantageous than the coating process by brushing in avoiding mixing of foreign matter into the work.

According to a third aspect of the present invention, the coating liquid supply means includes a storage tank for storing the coating liquid, a supply nozzle located above the coating processing roller and supplying the coating liquid to the roller, It is possible to adopt a configuration having a connection tube that connects the storage tank and the supply nozzle, and a dispenser provided in the middle of the connection tube. However, in this case, in order to prevent the inside of the storage tank from becoming a vacuum state, it is desirable to provide the storage tank with a small hole for introducing intake air. Further, when the storage tank has a large capacity, it is necessary to perform nitrogen purging or constant stirring as necessary.

With this configuration, since the coating liquid is supplied from the storage tank to the coating processing roller from the supply nozzle through the connection tube having the dispenser, the coating liquid is supplied to the outside air before being supplied to the coating processing roller. The state of not touching is maintained, and the solvent contained in the coating liquid does not volatilize. Therefore, the concentration of the coating liquid does not increase due to the volatilization of the solvent.

According to a fourth aspect of the present invention, the work transfer means includes a magnet member that comes into contact with the upper surface of the work and adsorbs the work, and an actuator that moves the magnet member to the drying processing position. It can be configured.

With this configuration, the work is attracted and held by the magnet member by using the magnetic force of the magnet member, and the work is moved to the drying processing position by the actuator in the attracted and held state. Therefore, by adsorbing the magnet member to the upper surface of the work not coated with the coating liquid by the magnet member, the work can be moved to the drying processing position without touching the portion where the coating liquid is coated. .

According to a fifth aspect of the present invention, the drying processing means has a nozzle directed to a surface of the work at the drying processing position, the surface being coated with the coating liquid, and air for supplying drying air to the nozzle. It may be configured to include a supply unit.

With this arrangement, the drying air supplied from the air supply means is supplied from the nozzle toward the work at the drying processing position. This makes it possible to perform a drying process of drying the coating liquid on the work within a short period of time after the coating process, and then, when it is necessary to stack them in an oven for baking, stack them. However, there is no danger of leaving a mark unlike the conventional case.

According to a sixth aspect of the present invention, in the roller supporting means, the column member is vertically divided into an upper member and a lower member, and the supporting member is supported by the upper member, while the supporting member is supported by the upper member. The lower member may be provided with an elevating means that supports the upper member so that the upper member can move up and down with respect to the lower member.

In this way, by raising the upper member by the elevating means, the coating processing roller can be displaced upward together with the supporting member so as not to come into elastic contact with the work. On the other hand, it is possible to easily avoid applying the coating liquid.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an explanatory diagram showing a schematic configuration of a coating / drying system according to the present invention, and FIG. 2 is an explanatory diagram showing a schematic configuration of a drying processing apparatus of the coating processing system.

The coating and drying system 1 according to the present invention is shown in FIG.
And, as shown in FIG. 2, the core bar support 2 (work support)
The core metal 3 (workpiece) is set on the supporting portion 2a of the above, and the core metal 3 is conveyed together with the core metal support base 2 while being coated by the coating processing device 11, and then dried by the drying processing device 12. This is done (see FIG. 2).

As shown in FIG. 1, a synchro belt 21 is connected to the cored bar support 2, and the synchro belt 21 is wound around a pulley 22a of a drive motor 22. Then, by rotating the synchro belt 21 by the driving motor 22, the cored bar support 2 on which the cored bar 3 is set is conveyed in a specific direction along the guide rail 24 placed on the base 23. It is supposed to be done. That is, a slider 25 that is slidably engaged with the guide rail 24 is provided below the cored bar support 2.
Is provided. In this way, the core bar support 2 is
Transfer device for transferring the core metal 3 between the core metal setting position P1 (work set position) for setting the core metal 3 on the core metal support base 2 and the core metal take-out position P2 for removing the core metal 2 from the core metal support base 2. 13 are configured.

While the work is being transferred by the transfer device 13, that is, between the core bar setting position P1 and the core bar take-out position P2, the surface (application surface) of the core bar 3 is on the base 23. The coating processing apparatus 11 for coating the adhesive liquid (coating liquid) on a predetermined portion is provided. The coating processing apparatus 11 is configured to bring a coating processing roller 31 impregnated with an adhesive liquid into contact with a predetermined portion of the core metal 3 to apply the adhesive liquid to the core metal 3. Here, the coating processing roller 31 has a shaft portion 31a and a roller portion 31b made of an elastic sponge provided in the central portion of the shaft portion 31a, and the roller portion 31b is impregnated with an adhesive liquid.

Further, when the cored bar 3 is positioned at the tip, the adhesive liquid is circulated to the back side of the cored bar 3 at the positioning portion.
As shown in FIG. 3, the core metal 3 is configured to be positioned between the support portion 2a and the back surface 3a. Even when the shapes of the cored bars 3 ′ and 3 ″ are different, as in FIGS. 4 (a) and 4 (b), the back surfaces 3a ′ and 3a ″ are connected to the support portions 2a ′ and 2a ″. It can be positioned.

The coating roller 31 is supported by a pair of plate-shaped supporting members 32 provided at regular intervals so that it can be displaced upward. That is, the pillar member 33 is erected on the base 23, and the pillar member 33 has an extension portion 33a extending above the movement path of the cored bar support 2, and the attachment member 34 is attached to the extension portion 33a. The pair of support members 32 are mounted and fixed in parallel with each other with an interval substantially corresponding to the length of the roller portion 31b of the coating processing roller 31. The support member 32 has a groove portion 32a that is opened upward, and supports the shaft portion 31a of the coating processing roller 31 in the groove portion 32a so that the shaft portion 31a can be displaced upward. In the case of the shape of the core metal 3 ″ as shown in FIG. 4B, the chamfered portion 32b of one support member 32 ′ is provided as shown in FIGS.
It is possible to make the roller 31 move up and down easily on the application surface of the core metal 3 ″ while ensuring the balance so that the roller 31 moves up and down by its own weight.

As described above, since the shaft portion 31a of the coating processing roller 31 is engaged with and supported by the groove portion 32a of the support member 32, the roller portion 31b of the coating processing roller 31.
Is elastically contacted with a predetermined portion (application surface) of the upper surface of the cored bar 3 being conveyed, only by its own weight of the application processing roller 31 itself. Here, when the roller diameter of the coating treatment roller 31 is large and the thickness of the roller portion 31b is large, it is difficult to make the amount of impregnation of the adhesive liquid constant over the entire circumference of the roller portion 31b. Therefore, it is desirable that the roller portion has a small thickness.

By positioning the core metal support 2 and the coating processing roller 31, the roller portion 31b to the end of the core metal 3 is schematically shown in FIGS. 6 (a) and 6 (b). The turning amount can be reduced or increased, and adjusted. In addition, the width of the coating range can be changed by changing the width of the roll portion 31b.

As shown in FIG. 1, the coating treatment apparatus 11 further includes a supply nozzle 36 which is attached to the upper portion of the support member 32 by a fixture 35 and supplies an adhesive liquid to the roller portion 31b of the roller 31. The droplets 37 of the adhesive liquid are supplied from the supply nozzle 36 located above the coating processing roller 31 to the roller portion 31b of the roller 31, and are supplied to the roller portion 31b made of sponge over the entire circumference. Like to penetrate. In this way, since the supply nozzle 36 is located above the roller portion 31b and the droplets of the adhesive liquid are dropped and supplied, the device structure is simplified.

The supply nozzle 36 is constructed so that the adhesive liquid is supplied from a storage tank 38 for storing the adhesive liquid via a connecting tube 39. This storage tank 3
A dispenser 40 for adjusting the amount of the adhesive liquid to be supplied is provided in the middle of the connection tube 39 connecting the 8 and the supply nozzle 36.

The cored bar 3 coated by the coating processor 11 is conveyed along with the cored bar support 2 along the guide rail 24 to the automatic take-out position P2, and the automatic take-out position P2 is shown in FIG. As described above, the transport device 51 removes the cored bar 3 from the cored bar support 2 and transports it to the drying processing position P3 located above the automatic take-out position P2.

The transfer device 51 includes a magnet member 42 (for example, an electromagnet) which comes into contact with the upper surface of the cored bar 3 and adsorbs the cored bar 3, and a cylinder for moving the magnet member 42 to the drying processing position P3. A means 43 (actuator) and a support base 44 for supporting the cylinder means 43 at a position of a predetermined height are provided, and the magnetic force of the magnet member 42 is used to hold the core metal 3, and in that state, the support base 44.
Along with this, the cylinder means 43 is contracted to move it to the upper drying processing position P3. It should be noted that instead of the magnet member 42, it is also possible to use an attraction means utilizing negative pressure (vacuum).

Adjacent to the automatic take-out position P2 or the dry processing position P3, as shown in FIG. 2, a dry processing device 12 for supplying dry air to the core metal 3 moved to the dry processing position P3 is provided. ing. This drying device 12
Includes an air nozzle 51 directed to the core metal 3 moved to the drying processing position P3, and an air hose 52 of an air supply means (not shown) for supplying drying air to the air nozzle 51. The air nozzle 51 is provided together with a mounting member 34 that supports the support member 32.

In this way, the cored bar support base 2 on which the cored bar 3 is set is moved along the guide rails 24 by the synchro belt 21. During the transfer, the coating processing apparatus 11 causes the core bar support 2 to move. The roller portion 31b of the application processing roller 31 impregnated with the adhesive liquid is brought into elastic contact with the core metal 3 to apply the adhesive liquid to a predetermined portion of the core metal 3.

By the rotation of the coating treatment roller 31, the application of the adhesive is started through the elastic sponge roller portion 31b, and as shown in FIG. 7, the coating area S1 having a certain width on one side of the core metal 3. The adhesive liquid is evenly applied to. Since the coating treatment roller 31 is idled on the cored bar support 2 at the beginning of coating, the coating of the adhesive liquid without unevenness is realized from the beginning of coating.

At the time of such coating, the coating processing roller 31 is provided with a vertical displacement function, and the core metal 3 is loaded by the weight of the roller.
Since it comes into elastic contact with the coating roller 3
1 (roller portion 31b) is brought into contact with the core metal 3 so that the roller portion 31b moves to the core metal 3 as shown in FIGS.
It is pushed up while deforming following the shape of the core metal 3, and is rotated (rotated) by the frictional force generated between the surface (application surface) of the core metal 3 and the roller portion 31b, and the contact with the core metal 3 is made. There is almost no resistance to the transfer of gold 3. Also,
The roller portion 31b does not hit the burrs of the core metal 3, but even if it hits, it rotates while deforming, so that the roller portion 31b (elastic sponge) is not damaged. Further, while the coating treatment roller 31 is rotated in the same manner as the core metal and the adhesive liquid is quantitatively discharged by the dispenser 40, the coating treatment roller 31 is in a state in which the roller portion 31b is constantly impregnated with the adhesive liquid over the entire circumference. Kept in.

Then, the core metal 3 coated with the adhesive liquid
Is removed from the cored bar support 2 by the magnet member 42 and conveyed to the upper drying processing position P3. Then, on the core metal 3 conveyed to the drying processing position P3,
Dry air is supplied through the air supply nozzle 51 of the drying device 12 so as to flow in parallel with the coating surface of the cored bar 3, and the adhesive liquid coated on the cored bar 3 is dried. Therefore, compared to the conventional case of natural drying, it can be dried earlier, and because it is baked after processing, even if it is placed in an oven for stacking, no traces remain, and there is no problem in appearance. .

In this way, a series of operations from the application process of the adhesive liquid to the drying process are automatically performed, and the manual work of the operator is reduced, and the burden on the operator is reduced.

In this case, in particular, the shaft portion 31 of the coating processing roller 31 is provided in the groove portion 32a of the support member 32 which is opened upward.
Since “a” is supported, the upward displacement of the coating processing roller 31 is allowed, and the roller portion 31b (elastic sponge) impregnated with the adhesive liquid comes into contact with and deforms only by the weight of the roller itself. Therefore, the coating treatment roller 31 rotates together with the movement of the cored bar 3 so that the coating treatment of the adhesive liquid is performed, which is an advantageous structure for avoiding mixing of foreign matter.

Further, from the storage tank 38, through the connection tube 39 having the dispenser 40 in the middle, from the supply nozzle 36 to the roller portion 31b of the coating processing roller 31.
Since the adhesive liquid is supplied to the upper part, the adhesive liquid does not come into contact with the outside air before being supplied to the coating processing roller 31, and the solvent contained in the adhesive liquid does not volatilize. Therefore, unlike the conventional manual work, the concentration of the adhesive liquid does not increase due to the evaporation of the solvent.

Since the core metal 3 is held by utilizing the magnetic force of the magnet member 42 and is moved to the drying processing position P3 by the cylinder means 43 in this state,
It is possible to move to the drying processing position P3 without touching the portion where the adhesive liquid is applied. In addition to this, the drying air supplied from the air supply means is supplied from the air supply nozzle 51 toward the core metal 3 at the drying processing position P3, so that drying is performed within a short period after the coating processing. It can be processed, and even if it is piled up thereafter, there is no possibility of leaving a mark unlike the conventional case.

In the above embodiment, the coating processing roller 31 does not move in the vertical direction, and as shown in FIG. 7, the adhesive liquid is coated on the coating region S1 having a constant width over the entire longitudinal direction of the cored bar 3. However, the present invention is not limited to this, and as shown in FIG. 9, the core metal 3 ′ ″ is adhered only to the coating area S2 excluding both end portions or any one end portion in the traveling direction. In order to apply the liquid, for example, as shown in FIG. 10, the support member 32 can be moved in the vertical direction, and the coating treatment roller 31 can contact the core metal 3 ″ ′ only when necessary. It is also possible to do so.

In this case, as shown in FIG. 10, a column member 33 'for supporting the supporting member 32 of the coating processing roller 31.
Is vertically divided into an upper member 33a and a lower member 33b. The tip member of the piston rod 41a of the cylinder means 41 (elevating means) is attached to the upper member 33a of the column member 33 ', and the lower member 33b is attached to the cylinder means. By fixing the cylinder bodies 41b of the cylinders 41 respectively, the upper and lower members 33a of the support member 33 'and thus the coating processing roller 31 can be moved up and down with respect to the lower member 33b by the expansion and contraction operation of the cylinder means 41.

Specifically, as shown in FIG. 11, in the initial state, the coating processing roller 31 is lifted by the cylinder means 41, and when the cored bar 3 enters the coating range, FIG. As shown, the cylinder means 41 contracts, the coating processing roller 31 descends, and the roller portion 31b.
Comes into elastic contact with the surface of the core metal 3 to start coating.

Then, as the cored bar 3 moves, the coating is performed while the coating treatment roller 31 rotates in the same direction. As shown in FIG. Flipped. Therefore, the application processing roller does not come into contact with a portion that does not need to be applied, so that the adhesive liquid is not applied.

Further, when the area opposite to the area where the application is not required reaches the area where the application is unnecessary, as shown in FIG.
The running of the core bar is stopped and the running direction is reversed. Then, when it moves to the portion where coating is first started, as shown in FIG. 15, the cylinder means expands, the coating processing roller 31 is raised, and contact is avoided. As a result, the area around the first application is applied three times as shown in FIG. Therefore, the part to be applied first is
Although the adhesive liquid may not be sufficiently applied, since it is applied three times, the application is surely applied to that portion as well.

[0050]

The present invention is implemented as described above and has the following effects.

According to the first aspect of the present invention, the work support table on which the work is set is conveyed in a specific direction by the transfer means, and the coating treatment roller impregnated with the coating liquid is brought into contact with the work during the conveyance. To apply the coating liquid, and then remove the workpiece coated with the coating liquid from the work support and convey it to the drying processing position.
Since the drying air is supplied by the drying treatment means to dry the coating liquid, a series of operations from the coating treatment of the coating liquid to the drying treatment can be automatically performed.
It is possible to reduce the burden on the operator by reducing the manual processing.

When the shaft portion of the coating processing roller is supported by the groove portion of the support member which is open upward as described in claim 2, the elasticity impregnated with the coating liquid is caused only by the weight of the roller. The sponge comes into contact with the work and is deformed, and when the work moves, the coating treatment roller rotates together, thereby performing the coating treatment of the coating liquid, which is an advantageous structure for avoiding contamination of foreign matter. Has become.

When the coating liquid is supplied from the storage tank to the coating processing roller from the storage nozzle via the connection tube having the dispenser, the coating liquid is supplied to the coating processing roller. The solvent does not come into contact with the outside air, and the solvent contained in the coating liquid does not evaporate. Therefore, the concentration of the coating liquid does not increase due to the volatilization of the solvent.

As described in claim 4, if the magnetic force of the magnet member is used to move the work to the dry processing position, the work is moved to the dry processing position without touching the portion where the coating liquid is applied. It becomes possible.

According to the fifth aspect, if the drying processing means is configured so that the drying air supplied from the air supply means is supplied from the nozzle toward the work at the drying processing position, after the coating processing is completed. It can be dried in a short period of time, and even if it is piled up thereafter, there is no possibility of leaving a mark as in the conventional case.

As described in claim 6, by raising the upper member by the elevating means, the coating processing roller is displaced upward together with the supporting member so as not to come into elastic contact with the work. On the other hand, it is possible to easily form a portion where the coating liquid is not applied.
