Description

The present invention relates to a paint recovery container and a paint guide member.

In order to paint objects to be painted such as automobiles and home appliances, the process of painting in the painting booth is widely used. In such a process, when changing the type or color of the paint to be painted on the object to be painted, it is necessary to replace the paint used in the painting device provided in the painting booth. When replacing the paint, it is first necessary to discharge the paint that has been used so far to the outside of the painting equipment. At this time, if the paint is discharged by a method of directly discharging the paint into the painting booth, for example, a paint mist having a higher concentration than that during normal painting work flows into the lower tank of the painting booth. When the paint mist of a high concentration flows in as described above, there is a possibility that the discharged paint mist solidifies and causes a problem such as blockage of the apparatus. Therefore, when the paint is discharged from the painting device, a member such as a container for collecting the discharged paint may be used.

For example, Japanese Patent Application Laid-Open No. 2011-125784 (Patent Document 1) allows a mist-like cleaning waste liquid discharged from a coating machine to be positively liquefied by contacting it with an umbrella-shaped contact body so that it can be recovered. Disclosed is a cleaning waste liquid recovery device. Further, Japanese Patent Application Laid-Open No. 2006-334574 (Patent Document 2) discloses a hopper for cleaning a coating machine, which can reduce the frequency of cleaning by reducing the concentration of stains in the main body.

Japanese Unexamined Patent Publication No. 2011-125784 Japanese Unexamined Patent Publication No. 2006-334574

However, it has been kept in mind that the paint recovery member such as the cleaning waste liquid recovery device disclosed in Patent Document 1 and the coating machine cleaning hopper disclosed in Patent Document 2 will be used repeatedly. Therefore, after using the member, maintenance work for removing the adhered paint is required, which may impair the workability of the paint recovery process. In addition, when recovering a paint containing a curable component such as a two-component clear paint, the paint may harden inside the paint recovery member and the flow path may be blocked. It was necessary to distribute a cleaning solvent, a curing inhibitor, etc. inside. In this method, in addition to using consumables such as cleaning solvents and anti-curing agents, it is necessary to install equipment for distributing these consumables separately from the painting equipment, which increases the cost required for installation and operation. There was a risk of doing so.

Therefore, it is necessary to realize a member for paint recovery that can improve the workability of the paint recovery process and reduce the cost required for installation and operation by omitting the dilution for preventing curing and the maintenance work after use. Is desired.

The paint recovery container according to the present invention includes a top surface portion having an inlet portion through which airflow can enter, a bottom surface portion having an exit portion, and a side surface portion extending between the top surface portion and the bottom surface portion, and the inside thereof. In addition, it is a tubular paint recovery container having a path that can guide the airflow that has entered from the inlet portion to the outlet portion, and the inlet portion can receive the paint discharge port of the coating device, and the inlet portion. In the middle of the straight path from the to the exit portion, a baffle plate portion provided intersecting the straight path portion is further provided, and the baffle plate portion is provided from each of the top surface portion, the bottom surface portion, and the side surface portion. , At least partially separated.

Further, the paint guide member according to the present invention has a top surface portion having an inlet portion through which an air flow can enter, a side surface portion extending from the top surface portion in a direction intersecting the direction in which the top surface portion extends, and an obstruction plate. A paint guide member provided with a portion and capable of guiding an air flow entering from the inlet portion, the inlet portion can receive a paint discharge port of a coating device, and the obstruction plate portion is a top surface portion. Provided so as to be separated from the top surface portion along the direction in which the side surface portion extends, intersect with the direction in which the side surface portion extends, and at least partially separated from the side surface portion. It is characterized by being painted.

According to these configurations, a member for recovering paint can be provided by a combination of plate-shaped members. Therefore, it is possible to provide a member for recovering paint by using a plate-shaped member suitable for disposable use such as cardboard. Therefore, by disposable use, maintenance work after use can be omitted. Further, since the paint recovery container or the paint guide member itself may be replaced before the flow path is blocked, dilution for preventing curing is not always necessary. As described above, since the paint recovery member can be provided by the combination of the plate-shaped members suitable for disposable use, the workability of the paint recovery process can be improved and the cost required for installation and operation can be reduced.

Hereinafter, preferred embodiments of the present invention will be described. However, the scope of the present invention is not limited by the preferred embodiments described below.

As one aspect, the paint recovery container according to the present invention further includes a guide plate portion extending from the bottom surface portion toward the inside and defining a flow path portion from the inside to the outlet portion. It is preferable that the storage portion is defined by the side surface portion and the guide plate portion, and at least a part of the paint discharged from the paint discharge port and entered the path from the inlet portion can be stored in the storage portion. ..

According to this configuration, the paint mist that flows out from the outlet can be reduced by liquefying the paint mist inside the paint recovery container and storing it in the storage section, so that the paint released into the paint booth can be reduced. The mist can be further reduced.

In one aspect of the paint recovery container according to the present invention, it is preferable that the projected area of the entrance portion with respect to the baffle plate portion is smaller than the area of the projection surface of the baffle plate portion.

[First Embodiment]
An embodiment of the paint recovery container according to the present invention will be described with reference to FIGS. 1 to 7. In the present embodiment, the paint recovery container according to the present invention is used as the paint recovery container 1 for recovering the paint discharged from the bell cup 102 (example of the paint ejection port) of the painting device 101 provided in the painting booth 100. The example used will be described.

The painting booth 100 has an upper tank 100a in which a painting device 101 is provided to perform painting work on an object to be painted, and a lower tank 100b provided with an exhaust facility having an exhaust fan 104, sandwiching the grating floor 103. .. A downward airflow is formed in the painting booth 100 from above to below, and an atmosphere containing the paint that has not adhered to the object to be coated is guided from the upper tank 100a to the lower tank 100b.

In the paint replacement step of replacing the paint used in the painting device 101, it is first necessary to discharge the paint used so far to the outside of the painting device 101. At this time, if the paint is discharged by a method of directly discharging the paint into the painting booth 100, a paint mist having a higher concentration than that during normal painting work flows into the lower tank 100b. When the paint mist of a high concentration flows in as described above, there is a possibility that the discharged paint mist solidifies and causes a problem such as blockage of the apparatus. Therefore, when the paint is discharged from the painting device 101, the paint is collected using the paint recovery container 1 to prevent the paint mist having a high concentration from flowing into the lower tank 100b. At this time, the paint recovery container 1 is housed in the casing 105 provided under the floor of the grating floor 103.

(Construction of paint collection container)
The paint recovery container 1 is a cubic cardboard container having a top surface portion 2, a bottom surface portion 3, and a side surface portion 4 and formed in a square cylinder shape (hollow cube shape) having a side of 350 mm (FIG. 2, FIG. 3). Further, a baffle plate portion 5 and a guide plate portion 6 are formed inside the paint recovery container 1. Unless otherwise specified, each part of the paint recovery container 1 is made of cardboard. Hereinafter, the structure of each part will be described in order. When the paint recovery container 1 is used, the bottom surface portion 3 is installed as a ground plane on the grating floor 103 (FIG. 1) in the painting booth 100. Therefore, in the following description, when referring to the vertical direction, the top surface portion 2 side is referred to as "upper" and the bottom surface portion 3 side is referred to as "lower".

The top surface portion 2 is a portion arranged on the upper side when the paint recovery container 1 is used, and is formed in a square shape having a side of 350 mm in the present embodiment. At the center of the top surface portion 2, an entrance portion 21 having a side opening of 130 mm in a square shape is provided. The opening size of the inlet portion 21 is a size that can accept the bell cup 102 provided at the tip of the painting device 101. The conductive adhesive tape 9 is attached to the entire top surface portion 2 except for the opening portion of the inlet portion 21.

The bottom surface portion 3 is a portion that becomes a ground contact surface when the paint recovery container 1 is used, and is formed in a square shape having a side of 350 mm in the present embodiment. At the center of the bottom surface portion 3, an outlet portion 31 having a side opening of 204 mm in a square shape is provided. In the painting booth 100 in which the paint recovery container 1 is used, an exhaust facility having an exhaust fan 104 is provided under the grating floor 103, and an air flow downward in the painting booth 100 is formed (FIG. FIG. 1). Therefore, when the paint recovery container 1 is installed in the painting booth 100, the air in the paint recovery container 1 is sucked into the exhaust facility through the outlet portion 31. As a result, an air flow 12 from the inlet portion 21 to the outlet portion 31 is formed inside the paint recovery container 1.

The side surface portion 4 extends over the top surface portion 2 and the bottom surface portion 3. That is, when the paint recovery container 1 is used, it extends along the vertical direction.

The baffle plate portion 5 is a plate-shaped member provided on the lower side of the top surface portion 2 substantially parallel to the top surface portion 2, and has a shape in which four corners of a square having a side of 260 mm are cut out. In other words, the obstruction plate portion 5 faces the entrance portion 21 of the top surface portion 2. As shown in FIG. 3, the baffle plate portion 5 is provided at least partially separated from any of the top surface portion 2, the bottom surface portion 3, and the side surface portion 4. In the present embodiment, the separation distance between the top surface portion 2 and the baffle plate portion 5 (the vertical width of the top surface portion 2, the baffle plate portion 5 and the gap 51) is set to 35 mm.

The baffle plate portion 5 is provided so as to intersect the virtual path in the middle of a linear virtual path (example of a straight path) from the inlet portion 21 to the exit portion 31. Note that FIG. 3 shows two arrows 11 representing the outer edge of the virtual path, and the virtual path is a three-dimensional region sandwiched between the two arrows 11. The projected area of the entrance portion 21 (square shape having a side of 130 mm) with respect to the baffle plate portion 5 (substantially square shape having a side of 260 mm) is the projection area of the baffle plate portion 5 (in other words, the baffle plate portion 5 in FIG. It is a surface along a surface orthogonal to the paper surface of.) It is smaller than the area of. Further, the projected area of the outlet portion 31 (square shape having a side of 204 mm) with respect to the baffle plate portion 5 is also smaller than the area of the projection surface of the baffle plate portion 5. That is, since the baffle plate portion 5 is provided so as to block the virtual path, the airflow 12 from the inlet portion 21 to the exit portion 31 passes through the path bypassing the baffle plate portion 5 as shown in FIG. To circulate.

The guide plate portion 6 extends from the edge portion of the outlet portion 31 of the bottom surface portion 3 toward the inside of the paint recovery container 1. In this embodiment, there are four guide plate portions 6, of which two extending orthogonally to the paper surface of FIG. 3 are referred to as guide plate portions 6a and extend parallel to the paper surface of FIG. The two may be distinguished as the guide plate portion 6b. It should be noted that one of the two guide plate portions 6b is not shown because it is located on the front side of the paper surface of FIG.

The guide plate portion 6 defines the flow path portion 61 and the storage portion 62. The flow path portion 61 is defined as a cylindrical space surrounded by guide plate portions 6 (6a, 6b) on all four sides, and is open to the outside of the paint recovery container 1 at the outlet portion 31. The lower portion of the storage portion 62 is defined by the bottom surface portion 3, the side thereof is defined by the side surface portion 4 and the guide plate portion 6, and the upper portion thereof is open.

(Construction of blanks constituting the paint recovery container)
Next, the structure of the blank constituting the paint recovery container 1 will be described. The paint recovery container 1 according to the present embodiment includes a first blank 7 (example of the first member, FIG. 4) and a second blank (example of the second member, FIGS. 5 and 6) made of flame-retardant cardboard. Consists of using. The term "blank" in the specification and claims of the present application means "a flat cardboard that has been processed before joining the cardboard boxes" as defined in JIS Z 0104: 2013. Same as. Further, only in the description of this embodiment and the second embodiment described later, the term "cardboard" is used to mean a cardboard made of paper.

Both the first blank 7 and the second blank 8 are cut out from a so-called W flute flame-retardant corrugated cardboard. The W flute referred to here is a corrugated cardboard plate having a thickness of 8 mm by laminating a corrugated cardboard plate of the A stage (A flute) and a corrugated cardboard plate of the B stage (B flute). The definitions of the A stage (A flute) and the B stage (B flute) are as defined in JIS Z 1516: 2003. The first blank 7 uses a corrugated cardboard plate in a direction in which the step direction of the corrugated cardboard plate is along the left-right direction of the paper surface in FIG. Similarly, the second blank 8 uses a corrugated cardboard plate in a direction in which the step direction of the corrugated cardboard plate is along the left-right direction of the paper surface in FIG.

The first blank 7 constitutes a top surface portion 2, a bottom surface portion 3, a side surface portion 4, and a guide plate portion 6a when the paint recovery container 1 is assembled. As shown in FIG. 4, the first blank 7 has a main body portion 71 in which four side surface portions 4 are linearly connected, of which two side surface portions 4 (the first from the left and the first from the left in FIG. 4). From the third), the flap 72 constituting the top surface portion 2 extends to one side, and the flap 73 constituting the bottom surface portion 3 and the guide plate portion 6a extends to the other side. Each of the flaps 73 is provided with two notches 73a. Further, the flap 74 constituting the bottom surface portion 3 extends from the remaining two side surface portions 4 (second and fourth from the left in FIG. 4) on the same side as the flap 73. In FIG. 4, for the sake of explanation, the spaces constituting the inlet portion 21 and the outlet portion 31 when the paint recovery container 1 is assembled are shown by broken lines.

The second blank 8 constitutes the baffle plate portion 5 and the guide plate portion 6b when the paint recovery container 1 is assembled. As shown in FIG. 5, the second blank 8 has a structure in which a baffle plate portion 5 is continuously provided between two guide plate portions 6b. Here, the boundary portion between the baffle plate portion 5 and the guide plate portion 6b is a bent cut line 81 located on three sides of a rectangle and a bend extending from both ends of the cut line 81 to the end of the second blank 8. It is composed of a line 82 and. As a result, in the assembled state of the second blank 8, a gap 84 is formed between the baffle plate portion 5 and the guide plate portion 6b (FIG. 6). The void 84 serves as a path for the air flow 12 in the paint recovery container 1. Further, each guide plate portion 6b is provided with a notch portion 83.

The assembled state of the first blank 7 and the second blank 8 is shown in FIG. As shown in the figure, the first blank 7 and the second blank 8 are engaged with each other by inserting the notch 83 of the second blank 8 into the notch 73a of the first blank 7. Further, the portion where the two flaps 72 are joined to each other (an example of joining between the portions of the first blank) is joined by using the conductive adhesive tape 9. Although not shown, the bonding of both ends 71a of the main body portion 71 of the first blank 7 is also performed using a conductive adhesive tape.

(Paint collection method)
Subsequently, a method of recovering the paint using the paint recovery container 1 will be described. When the paint is collected, the paint recovery container 1 is housed in the casing 105 provided under the floor of the grating floor 103 (FIGS. 1 and 8). The casing 105 has a side wall portion 105a extending downward from the grating floor 103, and a support portion 105b bent inward from the lower end of the side wall portion 105a. The vertical length of the side wall portion 105a is substantially the same as the vertical length of the side surface portion 4 of the paint recovery container 1, and when the paint recovery container 1 is placed on the support portion 105b, the glazing floor 103 and the paint are placed. The level of the collection container 1 is the same as that of the top surface portion 2. The length of the support portion 105b in the left-right direction is set so that the support portion 105b does not interfere with the outlet portion 31.

At this time, the conductive adhesive tape 9 attached to the outer surface (for example, the top surface portion 2) of the paint recovery container 1 is brought into contact with the grating floor 103. As a result, the paint recovery container 1 is grounded via the grating floor 103, so that it is possible to prevent the paint from being ignited by static electricity. When the paint recovery container 1 is installed, the airflow formed in the painting booth 100 enters the paint recovery container 1 from the inlet portion 21. Here, when the paint remaining inside the painting device 101 is discharged while the bell cup 102 is received by the inlet portion 21, the airflow entering from the inlet portion 21 and the fluid in which the bell cup 102 is integrated are generated. It is formed.

As shown in FIG. 3, since the air flow 12 from the inlet portion 21 to the outlet portion 31 is formed inside the paint recovery container 1, the paint mist discharged from the bell cup 102 (integrated with the air flow 12) is formed. Is attached to the upper surface of the baffle plate portion 5, or is guided to bypass the baffle plate portion 5. Here, since the separation distance between the top surface portion 2 and the baffle plate portion 5 is relatively narrow as 35 mm, the flow velocity of the air flow 12 flowing through the gap between the top surface portion 2 and the baffle plate portion 5 becomes relatively high. As a result, the paint mist discharged from the bell cup 102 is accelerated toward the side surface portion 4 in the gap 51 between the top surface portion 2 and the baffle plate portion 5. At this time, the paint mist collides with the upper end portion 4a of the side surface portion 4 after passing through the gap 51. Here, the paint mist loses propulsive force and adheres to the upper end portion 4a of the side surface portion 4, or is liquefied and then forms a flow 13 along the side surface portion 4 and is stored in the storage portion 62.

As described above, most of the paint mist discharged from the bell cup 102 adheres to the baffle plate portion 5 or the upper end portion 4a of the side surface portion 4, or is liquefied and then stored in the storage portion 62. Therefore, the amount of paint mist that goes out of the paint recovery container 1 from the outlet portion 31 is reduced. As a result, the amount of paint mist flowing into the lower tank of the painting booth 100 can be reduced, so that it is possible to prevent the painting booth 100 from malfunctioning due to the inflow of high-concentration paint mist.

After the paint collection is completed, the paint recovery container 1 to which the paint adheres is discarded. The paint recovery container 1 is made of corrugated cardboard and is low in cost in terms of both production and disposal, and is therefore suitable for disposable use. Therefore, it is not necessary to perform maintenance work such as removing the paint adhering to the paint recovery container 1.

[Second embodiment]
Next, an embodiment of the paint guide member according to the present invention will be described with reference to FIG. In the present embodiment, an example in which the paint guide member according to the present invention is used as the paint guide member 1'for collecting the paint discharged from the paint device 101 having the bell cup 102 (example of the paint discharge port) will be described. do. The same members as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted or simplified.

(Structure of paint guide member)
The paint guide member 1'is a corrugated cardboard member having a top surface portion 2, a side surface portion 4, and a baffle plate portion 5 (FIG. 8). Unlike the paint recovery container 1 according to the first embodiment, the paint guide member 1'has no bottom surface portion, and therefore the surface facing the top surface portion 2 is open.

The configuration of the top surface portion 2 is the same as that of the first embodiment, and an entrance portion 21 having an opening in a size capable of accepting the bell cup 102 is provided in the center of the top surface portion 2. The side surface portion 4 in the present embodiment extends from the edge portion of the top surface portion 2 in the direction Y where the top surface portion 2 intersects the extending direction X.

The configuration of the baffle plate portion 5 is the same as that of the first embodiment. As shown in FIG. 8, the baffle plate portion 5 is provided apart from the top surface portion 2 along the direction Y (direction produced by the side surface portion 4) from the top surface portion 2. In the present embodiment, the separation distance between the top surface portion 2 and the baffle plate portion 5 (the vertical width of the top surface portion 2, the baffle plate portion 5 and the gap 51) is set to 35 mm. Further, the baffle plate portion 5 is at least partially separated from the side surface portion 4.

The baffle plate portion 5 is provided so as to intersect the direction Y in the middle of a linear virtual path along the direction Y from the entrance portion 21. Further, as shown in FIG. 8, the projected area of the entrance portion 21 with respect to the baffle plate portion 5 is along the projection surface of the baffle plate portion 5 (in other words, the surface of the baffle plate portion 5 orthogonal to the paper surface of FIG. 8). It is smaller than the area of.). That is, since the baffle plate portion 5 is provided so as to block the virtual path, the airflow 12 passing through the paint guide member 1'distributes through the path bypassing the baffle plate portion 5 as shown in FIG. do.

The paint guide member 1'is configured by using the first blank 7'(FIG. 9) and the second blank 8'(FIGS. 10 and 11). The first blank 7'contains the top surface portion 2 and the side surface portion 4 when the paint guide member 1'is assembled. As shown in FIG. 9, the first blank 7'has a shape corresponding to the half of the first blank 7 on the flap 72 (top surface portion 2) side according to the first embodiment. That is, the first blank 7'has a main body portion 71'in which four side surface portions 4 are connected in a straight line, of which two side surface portions 4 (first and third from the left in FIG. 4). ), The flap 72 constituting the top surface portion 2 extends to one side.

The second blank 8'consists of the baffle plate portion 5 when the paint guide member 1'is assembled. As shown in FIG. 10, the second blank 8'has a shape in which the support portion 85 extends from the four corners of the baffle plate portion 5, and a bending line 86 is provided in the middle of the support portion 85. In the assembled state (FIG. 11), the main body portion 71 (side surface portion 4) of the first blank 7'and the support of the second blank 8'are supported in a state where all the bending lines 86 of the second blank 8'are bent in the same direction. The portion 85 is attached to the portion 85 with a conductive adhesive tape (not shown). As a result, the baffle plate portion 5 is fixed at a position separated from the top surface portion 2 and partially separated from the side surface portion 4.

(Paint collection method)
Subsequently, a method of collecting the paint using the paint guide member 1'will be described. When the paint is collected, the paint guide member 1'is housed in a casing provided under the floor of the grating floor 103, as in the first embodiment. Here, the casing is designed so that the levels of the grating floor 103 and the top surface portion 2 of the paint guide member 1'are the same. At this time, the conductive adhesive tape attached to the outer surface of the paint guide member 1'is brought into contact with the grating floor 103 and connected to the ground. Further, a drain pan (not shown) is installed in the lower tank 100b below the paint guide member 1'(direction Y side).

Similar to the first embodiment, when the paint remaining inside the coating device 101 is discharged in a state where the bell cup 102 is received by the inlet portion 21, the paint mist discharged from the bell cup 102 is discharged from the baffle plate portion 5. It adheres to the upper surface of the surface or is guided to bypass the baffle plate portion 5 along the air flow 12. Further, the paint mist is accelerated toward the side surface portion 4 in the gap 51 between the top surface portion 2 and the baffle plate portion 5, and after passing through the gap 51, collides with the upper end portion 4a of the side surface portion 4. Here, the paint mist loses propulsive force and adheres to the upper end portion 4a of the side surface portion 4, or is liquefied and then forms a flow 13 along the side surface portion 4 and is stored in the drain pan. As described above, also in this embodiment, the amount of paint mist flowing into the lower tank of the painting booth 100 can be reduced, so that it is possible to prevent the painting booth 100 from malfunctioning due to the inflow of high-concentration paint mist. The paint guide member 1'is made of corrugated cardboard and is suitable for disposable use, as in the first embodiment.

[Other embodiments]
Finally, other embodiments of the paint recovery container and the paint guide member according to the present invention will be described.
