Description

[Technical field]

[0001] The present invention relates to a hybrid flame treatment apparatus and a hybrid flame treatment method for a resin molded product. More specifically, the present invention relates to a hybrid flame treatment device that performs a deburring flame treatment on a resin molded product having a burr and a surface temperature equal to or higher than a predetermined temperature, and also performs a silicate flame treatment for easy adhesion, and a hybrid flame treatment method using the same. [Background technology]

[0002] Conventionally, deburring work for resin molded products having burrs on their peripheral edges has consisted of a process of separating the resin molded product from the burr, and a process of melting and smoothing the minute burrs remaining on the peripheral edges of the resin molded product to perform the deburring finish. This was a very time-consuming process and was a factor in increasing the manufacturing cost of the finished product.

[0003] In response to this, a deburring device has been proposed that separates the resin molded product from the burr, melts the burr remaining on the resin molded product, and adsorbs it to the resin molded product by its surface tension, smoothing out the burr portion (see, for example, Patent Document 1). 18(a), the deburring device 200 is configured with holding means 201 for holding a resin molded product having a burr on its periphery, high-temperature gas ejection means 202 for ejecting high-temperature gas that melts the material that constitutes the burr, and a three-dimensional drive device 203 for driving the high-temperature gas ejection means 202 so as to eject high-temperature gas along the resin molded product and onto the burr portion adjacent to the resin molded product. The deburring device 200 proposed uses the high-temperature gas ejection means 202 to melt the portion of the burr adjacent to the resin molded product, separating the resin molded product from the burr, and melts the burr remaining on the resin molded product and adsorbs it to the resin molded product by its surface tension to smooth it.

[0004] Also, as shown in FIG. 18(b), a method has been proposed in which burners 302 are placed across the width of a lattice body 301 in a direction intersecting the transport direction while the lattice body 301 is being transported, and the burrs are removed by passing the lattice body 301 through the flame of the burner 302 (see, for example, Patent Document 2). That is, the burrs extending from the main body of the lattice body 301 are thin and have a small heat capacity, so they melt and disappear quickly when exposed to the flame of the burner 302. The melted burrs then become integrated with the main body of the lattice body 301 due to surface tension, forming a smooth surface. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 6-71658 A (Claims) [Patent Document 2] JP 11-54127 A (Claims) Summary of the Invention [Problem to be solved by the invention]

[0006] However, the deburring devices disclosed in Patent Documents 1 and 2 each focus only on deburring resin molded products, and there is no concept of performing the next process of surface modification treatment (primer treatment or corona flame treatment) before painting at the same time in the same section. Therefore, after the deburring of the resin molded product was completed, it was necessary to transport it from the deburring section to the surface modification section using a specified transport device, and after a specified time had passed, a specified surface modification process was carried out.

[0007] Therefore, it was necessary to provide a device for transporting the resin molded products from the deburring section to the surface modification section, which required additional time for the transport, resulting in low yields in terms of production time and costs, and was also extremely disadvantageous in terms of miniaturization. In addition, while the resin molded product is being transported from the deburring section to the surface modification section, the surface of the resin molded product becomes electrically charged, and dust and other foreign matter tend to adhere to the surface. Furthermore, while the resin molded product is being transported from the deburring section to the surface modification section, the temperature of the resin molded product effectively drops to room temperature, making it prone to condensation, which can lead to problems such as uneven processing when performing specified surface modification or painting processes.

[0008] As a result of extensive research, the inventors of the present invention found that by performing a deburring flame treatment and a silicating flame treatment for easy adhesion on a resin molded product having a surface temperature of a specified temperature (e.g., 50°C or higher) in the same section, it is possible to perform each treatment effectively in an extremely short time and in a small space, and thus completed the present invention.

[0009] In other words, the present invention aims to provide a hybrid flame treatment device that can significantly shorten the total treatment time (hybrid treatment time) for deburring flame treatment and silicate flame treatment of resin molded products and that makes it easy to miniaturize the treatment device, and a hybrid flame treatment method using the same. [Means for solving the problem]

[0010] According to the present invention, there is provided a hybrid flame treatment apparatus for performing deburring flame treatment and silicating flame treatment on a resin molded product having a burr and a surface temperature of at least 50°C or higher, the hybrid flame treatment apparatus comprising: a second robot arm as a holding device for moving and holding the resin molded product to a predetermined position; and a first robot arm equipped with at least one flame treatment device for performing deburring flame treatment and silicating flame treatment on the resin molded product held by the holding device, thereby solving the above-mentioned problems. In other words, according to the hybrid flame treatment device of the present invention (a combined treatment device of silicate flame treatment device + non-silicic acid flame treatment, hereinafter sometimes simply referred to as hybrid flame treatment device), it is possible to perform a combined treatment of burr removal flame treatment and silicate flame treatment (hereinafter sometimes simply referred to as hybrid flame treatment device) on a resin molded product having a burr and a predetermined surface temperature in the same section, essentially at the same time. Therefore, it is possible to effectively provide a hybrid flame treatment apparatus that can significantly shorten the hybrid flame treatment time, can be easily miniaturized, and has little adhesion of foreign matter due to antistatic treatment. Furthermore, the removed resin molded product can be subjected to the hybrid flame treatment and painting treatment without being cooled to room temperature, so that condensation conditions are unlikely to occur and coating can be performed more evenly.

[0011] Furthermore, when constructing the hybrid flame treatment device of the present invention, it is preferable that at least one flame treatment device has a deburring flame treatment device that performs deburring flame treatment on a resin molded product, and a silicification flame treatment device that performs silicification flame treatment on a resin molded product, and has a switching device for switching between the deburring flame treatment device and the silicification flame treatment device. By configuring it in this manner, it is possible to easily select and perform deburring flame treatment and / or silicating flame treatment in accordance with a desired location in a resin molded product (e.g., an edge or a portion to be decorated).

[0012] Furthermore, when constructing the hybrid flame treatment device of the present invention, it is preferable that the gripping device is a robot arm that moves on multiple axes as the second robot arm, and that the second robot arm has a function as a means for removing the resin molded product from the mold molding section in the previous process and transporting it to a predetermined position where the deburring flame treatment and the silicate flame treatment are performed. By configuring in this manner, the position of the resin molded product can be easily changed to correspond to the desired processing position, regardless of the size or length of the resin molded product, and thus deburring flame processing and silicating flame processing can be performed more accurately and in a shorter time.

[0013] Furthermore, when constructing the hybrid flame treatment device of the present invention, it is preferable that the flame treatment device is attached to a robot arm that moves on multiple axes as a first robot arm, and that the first robot arm has a function of transporting the resin molded product after the specified treatment to the painting section in the next process. By configuring in this manner, deburring flame treatment and silicating flame treatment can be performed more accurately and in a shorter time via the first robot arm in accordance with the desired treatment position regardless of the size or length of the resin molded product.

[0014] In constructing the hybrid flame treatment device of the present invention, it is preferable that the flame treatment section is of a pilot ignition type and has a sensor for detecting the ignition state and extinguishing state of the flame treatment section. This configuration contributes to reducing the amount of combustion gas in the flame treatment section, and furthermore, the deburring flame treatment and the silicate flame treatment can be performed and terminated more reliably by using sensors that detect the ignition and extinguishing states.

[0015] It is also preferable that the first robot arm has multiple robot arms (including a multi-arm robot arm) including a 1A robot arm that performs deburring flame treatment and a 1B robot arm that performs silicate flame treatment. With this arrangement, the deburring flame treatment and the silicating flame treatment can be performed on different target products during a given production line, thereby further increasing the number of products produced per hour. Furthermore, the 1A robot arm and the 1B robot arm can perform each flame treatment simultaneously, further shortening the production time per product (hereinafter sometimes referred to as cycle time).

[0016] It is also preferable that the first robot arm has a load measuring unit that measures the weight of the resin molded product and / or a thickness measuring unit that measures the thickness of the resin molded product on a fixture on which the resin molded product is placed. By adopting this configuration, various flame treatments can be carried out while checking the quality, such as the weight and thickness, of the resin molded product, thereby making it possible to further reduce variation in quality.

[0017] Another aspect of the present invention is a hybrid flame treatment method in which a resin molded product having burrs and a predetermined surface temperature (at least 50°C or higher) is subjected to deburring flame treatment and silicating flame treatment by at least one flame treatment unit, the hybrid flame treatment method comprising the following steps (1) and (2): (1) A gripping process in which a resin molded product with a specified surface temperature is moved to a specified position and held there. (2) A hybrid deburring process in which a flame treatment unit performs a silicate flame treatment for easy adhesion on a resin molded product held by a gripping device at a predetermined surface temperature, and also performs a deburring flame treatment on the resin molded product. By carrying out the process in this manner, it is possible to perform deburring flame treatment and silicating flame treatment on a resin molded product having a burr and a predetermined surface temperature (at least 50°C or higher) in the same section by at least one flame treatment section. Therefore, the total processing time of the deburring flame processing and the silicate flame processing can be significantly shortened, and the device can be easily miniaturized, and the specified processing can be performed with less adhesion of foreign matter due to the antistatic treatment.

[0018] In carrying out the hybrid flame treatment method of the present invention, it is preferable to carry out the deburring flame treatment and the silicification flame treatment simultaneously in step (2). By carrying out the process in this manner, it is possible to carry out deburring and flame silicidation treatment at desired positions on a resin molded product (for example, edges or portions to be decorated) in a single operation in a short time.

[0019] In addition, when carrying out the hybrid flame treatment method of the present invention, it is preferable that the step (2) includes a switching step between the deburring flame treatment and the silicidation flame treatment, and that the silicidation flame treatment is carried out after the deburring flame treatment. By carrying out the process in this manner, it is possible to easily select and carry out the deburring flame treatment and the silicating flame treatment as hybrid flame treatments in accordance with desired locations on the resin molded product (e.g., edges or areas to be decorated).

[0021] [First embodiment] The first embodiment, as exemplified in Figs. 1 and 2, is a hybrid flame treatment device 10 that performs deburring flame treatment and silicification flame treatment on a resin molded product having a burr and a surface temperature of 50°C or higher. The hybrid flame treatment device 10 is characterized by having a second robot arm 24 as a gripping device that moves and holds the resin molded product 12 to a predetermined position, and a first robot arm 22 equipped with at least one flame treatment device 18 that performs deburring flame treatment and silicating flame treatment on the resin molded product 12 held by the gripping device. Hereinafter, embodiments of the hybrid flame treatment device of the present invention (hereinafter, may be simply referred to as hybrid flame treatment device) will be specifically described with reference to Figs. 1 to 6 as appropriate.

[0022] 1.Basic configuration (1) Hybrid flame treatment device As illustrated in Figures 1 and 2, the hybrid flame treatment device 10 is basically an apparatus that performs hybrid flame treatment on a resin molded product 12 that has burrs after mold molding and has a predetermined surface temperature (at least 50°C or higher). Therefore, the apparatus is provided with at least one flame treatment section 18 which, while carrying out flame treatment, heats the surface and edges including part of the side surface of the resin molded product 12 as the treated object to remove burrs, and also carries out flame silicification treatment, which is an easy-adhesion treatment.

[0023] Also, as shown in FIG. 3, in the hybrid flame treatment device 10, it is preferable that at least the flame treatment device 18, which is equipped with a burner 18a or the like at its tip, is attached to a robot arm (sometimes referred to as a first robot arm) 22 capable of moving on multiple axes. Therefore, the first robot arm is preferably a six-axis robot arm so that it can be moved arbitrarily, including rotationally moving 360 degrees.

[0024] As shown in FIG. 4(a), it is preferable that the flame treatment unit 18 share a burner for deburring and a burner for silicic acid flame treatment in order to shorten the flame treatment time, and is configured to eject at least one flame for silicic acid flame treatment. Of course, even when such a deburring burner and a silicating flame treatment burner are shared, it is preferable to provide a predetermined switching device in the flame treatment unit 18 to accommodate various resin molded products and usage patterns, and to eject only a deburring flame (non-silicic flame) from one burner, or to eject only a silicating flame.

[0025] Therefore, in the case of the flame treatment unit 18 shown in Figure 4 (a), the first robot arm 22, which moves on multiple axes, is equipped with a burner that serves both as a deburring burner and a burner for silicate flame treatment, and while moving along six axes along a route that has been taught in advance the shape of the resin molded product 12, it can spray silicate flames at predetermined locations such as edges of the resin molding mold that have burrs, thereby simultaneously treating them.

[0026] On the other hand, as shown in FIG. 4(b), the flame treatment section 18' is provided with a burner 18x for a silicic acid flame treatment and a burner 18y for deburring, and the flame for deburring and the flame for a silicic acid flame treatment may be ejected simultaneously, or the predetermined flames may be ejected sequentially within a short period of time, for example, within 60 seconds. By configuring in this manner, it is possible to accommodate resin molded products with large areas or widely differing shapes, and it is also possible to quickly respond to burner malfunctions, etc., and it is also possible to omit the required switching device.

[0027] Therefore, in the case of the flame treatment section 18' shown in Figure 4(b), the first robot arm 22, which moves on multiple axes, is taught the shape of the resin molded product 12 in advance, and can move, for example, on six axes to virtually simultaneously eject a deburring flame and a silicate flame treatment flame.

[0028] Specifically, as shown in Figures 1 and 2, it is also preferable that a first robot arm 22 for hybrid deburring processing performs a predetermined hybrid deburring processing on a resin molded product 12 held by a second robot arm 24. More specifically, while the resin molded product 12 is held by the second robot arm 24, it is preferable to subject the side surface (side A) including the edge of the resin molded product 12 to hybrid deburring treatment by the flame treatment unit 18 of the first robot arm 22. Then, it is preferable to rotate the resin molded product 12 horizontally through a predetermined angle (about 180°) and perform a hybrid deburring process on the side surface (side B) including the edge portion. That is, this is to prevent interlocking between the flame treatment section 18 of the first robot arm 22 and the second robot arm 24. Although there is no strict distinction between side A and side B, in the case of a bumper as an example, the edge on the vertically upper side when attached to a car is usually considered to be side A, and the edge on the vertically lower side is usually considered to be side B.

[0029] In another embodiment, after performing hybrid deburring on the side (side A) including the edge of the resin molded product, it is preferable to move the robot arm around to the opposite horizontal side of the resin molded product and perform hybrid deburring on the side (side B) including the edge. The reason for this is that by adopting this configuration, even if the gripping device is a simple device that moves on two axes, vertical and horizontal, it is possible to more efficiently prevent interference between the flame treatment section of the robot arm and the gripping device.

[0030] (2) Resin molded products A typical example of a resin molded product 12, which is an object to be deburred (including deburring finishing), is an automobile bumper as shown in FIG. Such resin molded products can be used for various automobile parts such as automobile interior materials, automobile front panels, and automobile seats. This is because these automobile parts are large resin molded products that are prone to multiple large and small burrs, but at the same time, for appearance and safety reasons, they are required to have a smooth surface.

[0031] More specifically, such automobile parts, in particular bumpers, are preferably resin molded products of a predetermined shape obtained by injection molding or blow molding using a mold from polypropylene resin (hereinafter sometimes referred to as PP) or other olefin resins, or furthermore polyurethane resin, polyester resin, polyamide resin, or the like.

[0032] In addition, immediately after molding, the resin molded product released from the mold usually has a thin burr on the peripheral portion of the resin molded product that corresponds to the parting line of the mold. Therefore, with the hybrid flame treatment device 10 of the present invention, for thin burrs, for example flat burrs having a thickness of less than 0.01 to 1 mm, it is possible to perform only silicate flame treatment and to modify the surface of the peripheral portion of the resin molded product, including part of the side portion (side A and side B).

[0033] On the other hand, for relatively large burrs, for example flat burrs with a thickness of about 1 to 10 mm, it is preferable to selectively perform normal flame treatment (non-silicic acid flame treatment) for a relatively long period of time, and then perform silicatic acid flame treatment for a relatively short period of time. That is, by performing flame treatment in two stages, a non-silicic flame treatment and a silicic flame treatment, which are switched between, the consumption of relatively expensive silicon-containing compounds that generate silicic flames can be relatively reduced.

[0034] The size of such a resin molded product, in the example of an automobile bumper shown in FIG. 6, is preferably 1000 to 2000 mm in width, 200 to 800 mm in depth, 200 to 500 mm in height, and the circumferential length of each resin molded product is preferably 2000 to 5000 mm. However, if the resin molded product generates burrs of multiple sizes and thicknesses, the hybrid flame treatment device of the present invention can be suitably applied even if the dimensions are outside of these limits.

[0035] 2. Flame treatment unit 1 Next, referring again to FIG. 3 and FIG. 4, the flame treatment section 18 that melts the burr material and ejects the silicification flame will be described in more detail. That is, as shown in FIG. 3, the first robot arm 22 can move appropriately in three mutually perpendicular directions, the X-axis, the Y-axis, and the Z-axis, as indicated by the arrows, and each of these can also be rotated, so that it is preferably configured as a six-axis robot arm. Such a first robot arm can be moved to any position in any direction of 360° by a servo motor or a pulse motor, and accordingly, the flame treatment section 18 can be moved to a predetermined position relative to the resin molded product.

[0036] As shown in Figures 1 and 2, the first robot arm 22 is connected to a control device 26, and the position movement of the flame treatment unit 18 attached to the first robot arm 22 can be controlled via the control device 26, thereby efficiently carrying out a hybrid flame treatment consisting of a deburring flame treatment and a silicating flame treatment. That is, the flame treatment unit of the first robot arm can perform hybrid flame treatment on the resin molded product held in the held state by spraying a silicate flame in a tracing manner while maintaining a constant distance, for example a predetermined distance of 0.1 to 10 cm, between the surface or edge of the resin molded product maintained in an approximately horizontal direction.

[0037] Here, it is generally preferable that the flame treatment section 18 be provided with a predetermined burner 18a as shown in Figs. That is, for burrs on the edges of resin molded products, a flame treatment unit 18 equipped with a specified burner 18a can be used to selectively perform flame treatment using a silicate flame to smooth the surface and to perform an easy-adhesion treatment as a surface modification treatment.

[0038] The silicic acid flame treatment refers to an adhesion-improving technique in which a predetermined amount (for example, 10 mol % or less when the total amount of fuel gas is 100 mol %) of a silicon-containing compound (tetramethylsilane, hexamethyldisiloxane, hexamethyldisilazane, etc.) and, as an optional component, an alcohol such as ethanol, are added to the fuel gas, and the silicic acid flame derived from this is sprayed onto the surface of the workpiece to strengthen the adhesion of the coating film formed on the surface.

[0039] However, at least one burner is sufficient, and more specifically, it is preferable to provide a burner that emits a silicidation flame for deburring, and a burner that emits a silicidation flame for surface modification. As shown in FIG. 4(a), the end of the burner 18a is connected via a pipe 18d to a fuel source containing a fuel gas (which in the case of a silicification flame treatment contains a predetermined silicon-containing compound and an alcohol compound as an optional component), and it is preferable to transport the predetermined fuel gas appropriately and combust it at the outlet of the burner 18a. It is preferable to introduce air (oxygen) to be mixed with the fuel gas into the end of the burner 18a via a pipe 18c, in addition to the pipe 18d.

[0040] Here, the burner provided in the flame treatment section is a device for spraying a flame derived from a fuel gas (containing a predetermined amount of a silicon-containing compound) obtained by uniformly mixing a combustible gas such as propane gas or natural gas transported through a pipe with air transported through a pipe at a joint section. Therefore, the form of the flame treatment section is not particularly limited, but for example, it is preferable to use a burner having a plurality of gas outlets arranged in parallel. That is, a burner comprising a gas inlet, a burner body, a burner extension, a gas flow meter, a valve, a gas storage unit, etc., arranged in parallel and laterally is preferred.

[0041] It is preferable that the LPG gas and oxygen, etc. introduced from two different gas inlets via gas flow meters are not mixed on the way to the gas outlet, so that pressure loss is minimized. In this case, it is preferable that the burner be a so-called pre-mixed type. Furthermore, it is preferable to provide a control plate at the burner outlet in the direction of injection, or at least above the direction of injection, so that the flame can be injected only at a predetermined position and is not radiated to an unintended location.

[0042] Although it depends on the type of fuel gas and resin molded product, the flame temperature is preferably in the range of about 500 to 1000°C and the flame length is preferably in the range of about 5 to 40 mm. A flame is sprayed from the burner 18a against the burrs on the resin molded product, and the burrs are removed while melting and smoothing the burrs. As shown in FIG. 4(a), in order to perform the deburring operation more selectively, it is preferable to set the inner diameter of the tip hole 18b of the burner 18a to 0.2 to 2.0 mm and eject the flame.

[0043] 3. Flame treatment unit 2 Moreover, as shown in FIG. 5, a preferred embodiment is one in which the flame treatment unit 18 is of a pilot ignition type. The reason for this is that by configuring the flame treatment section 18 in this manner, it is possible to improve the durability of the ignition section when repeatedly igniting the burner 18a, etc., and to suppress the flying of sparks, thereby ensuring safety.

[0044] Also, in the flame treatment section, by repeatedly igniting and extinguishing the flame in a very detailed manner, the consumption of fuel gas can be reduced and the amount of carbon dioxide generated can be reduced. In other words, if the flame treatment section were to constantly inject flame, a large amount of fuel gas would be consumed, which would not only be wasteful but could also be unsafe. By adopting a pilot ignition method and preparing a pilot flame that consumes less fuel gas, the consumption of fuel gas can be significantly reduced. In addition, because it is a pilot flame, problems such as excessive ignition are also reduced.

[0045] As shown in FIG. 5, it is preferable to detect this condition using a flame detection means 19, which is a sensor, and to use a safety device to reliably stop the flame irradiation in the flame treatment unit 18, or, depending on the conditions, to reignite the flame. For example, by providing an ultraviolet photocell Ultra Vision (manufactured by Yamatake Advance Automation Company) 19b as the flame detection means 19, it is possible to confirm that the pilot flame 19c is lit.

[0046] In this case, if it is confirmed that the pilot flame 19c has gone out, the supply of fuel gas for the pilot flame 19c will be stopped, as shown in Fig. 5. Furthermore, by providing another flame detection means 19a, it is possible to confirm that the fire has spread from the pilot flame 19c to the burner 18a and is lit, and that a stable flame is being sprayed from the burner 18a. Therefore, by configuring the flame treatment unit 18 in this manner with multiple flame detection means 19a, 19b, the safety and economy of the flame treatment unit 18 can be ensured, and a high level of stability can be maintained in the deburring operation.

[0047] 4. Switching device Next, although it is an optional configuration, it is also preferable to provide a switching device for switching between the deburring flame treatment and the silicating flame treatment. More specifically, the switching device is a control device that performs a switching function between the silicic acid flame treatment and the normal flame treatment (non-silicic acid flame treatment). Therefore, via this control device, the type of flame in the flame treatment unit attached to the robot arm can be switched, and hybrid flame treatment (a combination of silicate flame treatment and deburring flame treatment) or only deburring flame treatment can be efficiently performed depending on the size of the burr, the surface modification area, etc.

[0048] It is preferable that the control device serving as the switching device includes a position control system for a robot arm, a teaching mechanism (shape storage device) for a resin molded product, or the like. The reason for this is that by providing such a control device, the location of the resin molded product can be accurately recognized, and further, burrs can be removed uniformly and quickly at the flame generation area regardless of the shape, size, etc. of the resin molded product. Then, after the control device recognizes and stores the position, shape, etc. of the resin molded product, it can operate the robot arm based on the recognized information to reliably perform deburring and silicate flame treatment.

[0049] 5.Gripping device As illustrated in Figs. 1 and 2, the hybrid flame treatment device 10 is characterized by having a second robot arm 24 as a gripping device. The second robot arm is a device for holding the resin molded product in a predetermined position when the flame treatment section performs the deburring flame treatment and the silicating flame treatment on the resin molded product. Therefore, as shown in Figs. 1 and 2, it is preferable to provide a suction device 14 for sucking and lifting the surface of the resin molded article 12. Furthermore, although not specifically shown, it is also preferable to provide a clamp device at the tip of the robot arm for clamping the resin molded product.

[0050] Moreover, the second robot arm serving as a drive unit for the gripping device is preferably a robot arm that moves along multiple axes. That is, as illustrated in FIG. 1, the second robot arm 24 is preferably an arm that operates in at least two axes: a vertical direction (Z-axis) and one axial direction (X-axis or Y-axis) along the horizontal direction. It is preferable that the second robot arm has a function as a means for removing the resin molded product from the mold molding section in the previous process and transporting it to a predetermined position where deburring flame treatment and silicating flame treatment are carried out. The reason for this is that with such a second robot arm, the resin molded article can be easily held in a predetermined position, and the resin molded article can be subjected to the hybrid flame treatment as is. Furthermore, the holding device can also be used as a transport device to remove the resin molded product from the mold molding section and move it to the hybrid flame treatment area, which can contribute to reducing the size of the hybrid flame treatment device. Therefore, the second robot arm is preferably capable of rotational movement in at least one direction, and more preferably capable of rotational movement in three directions. Here, as described below, when the hybrid flame treatment device has a fixture for placing the resin molded product, the second robot arm does not need to continue to hold the resin molded product during flame treatment, and it is preferable to use it as a transport device for transporting the resin molded product.

[0051] Moreover, the gripping device preferably includes a conveying device, a moving device, a rotating device, and the like in the second and third embodiments described later. The reason for this is that the inclusion of such a device allows the predetermined processing to be carried out more quickly and accurately.

[0052] 6. Temporary Fixtures Although not specifically shown, the temporary fixing device for resin molded products is preferably provided with a platform for temporarily placing a resin molded product having burrs on its peripheral edge when it is removed from a specified resin molding machine. The reason for this is that by using such a temporary fixing device for a resin molded product, it becomes easy to adjust the surface temperature of the resin molded product, and the time spent adjusting the temperature can be utilized to produce the next resin molded product using a metal mold, etc. In addition, such a temporary fixing device for a resin molded product is preferably composed of a boat-shaped frame with raised end portions, a suction device, and a stopper so as to correspond to the external shape of the resin molded product, such as an automobile bumper.

[0053] Furthermore, although not specifically shown, the suction device for the resin molded product is preferably made up of a suction part, a suction chamber made of an elastic member, and a pressure valve for adjusting the pressure of the suction part. The reason for this is that such a suction device is basically made of an elastic material, so that even a relatively large resin molded product can be securely fixed without causing damage to the surface, etc.

[0054] 7. Housing Although not specifically shown, from a safety standpoint, it is preferable that the flame treatment unit is housed in a housing assembled into a roughly rectangular parallelepiped shape, and that the housing has an area for placing the flame treatment unit, etc., a hybrid flame treatment area for hybrid deburring, and an entrance area for transporting plastic molded products having a predetermined burr. That is, it is preferable that a wall panel is provided to cover the exterior of the housing, and that a hybrid flame of the flame treatment section is configured not to leak to the outside.

[0055] Moreover, the housing has an opening for carrying in a resin molded product having a predetermined burr from the metal molding section, and it is preferable that a shutter is provided at the opening. Furthermore, the housing has an opening for carrying out the resin molded product to the next process after deburring, and it is also preferable that a shutter is provided at the opening. In other words, by being contained in the housing, the safety and economy of the flame treatment unit can be ensured, and by driving the robot arm, it is possible to ensure rapid deburring flame treatment work for plastic molded products having a certain number of burrs.

[0056] The housing also preferably has two movable rails attached to the bottom. The reason for this is that the resin molded product to be subjected to the hybrid flame treatment can be removed from the mold molding section and quickly transported to a predetermined position in the hybrid flame treatment area.

[0057] On the other hand, it is also preferable to transport the resin molded product to be deburred, which has been removed from the mold by the second robot arm, to a hybrid flame treatment area for hybrid deburring while its surface temperature is, for example, 50°C or higher, more preferably a surface temperature of 50 to 80°C, and even more preferably a surface temperature of 55 to 75°C. In this state, it is also preferable to carry out a hybrid deburring process using a flame treatment section.

[0058] 8. Pretreatment Section It is preferable to provide a predetermined pre-treatment section as a pre-processing step prior to the surface modification treatment of the resin molded product by the hybrid flame treatment device. That is, as shown in Figures 1 and 2, a mold molding section 30 for a resin molded product 12 is usually provided, and in this mold molding section 30, polypropylene resin or the like is introduced in a molten state into a specified mold using an injection molding machine, an extrusion molding machine, or the like, to preferably form a resin molded product such as an automobile bumper. Therefore, the resin molded product 12 at a predetermined temperature is transported from the mold molding section 30 to the hybrid flame treatment area via the transport path 32 using the second robot arm 24.

[0059] Specifically, as an example, the pre-treatment section preferably includes a first mold corresponding to the back side of the resin molded product, a second mold corresponding to the front side of the resin molded product, a mold clamping device that clamps the first mold and the second mold, and an injection molding machine that injects resin into the inside of the molds combined by the mold clamping device. The reason for this is that with this configuration, after the resin molded product has been molded, one half of the resin molded product can be easily exposed by separating the first and second molds. The exposed surface can be sucked by a suction device provided on the transport device and easily transported to a predetermined position in the hybrid flame treatment area, which is the next process. Therefore, it is preferable to automatically perform a series of operations such as clamping the first and second molds, injecting resin into the clamped molds using an injection molding machine, separating the first and second molds, and removing the exposed resin molded product using a conveying device. Furthermore, each component can be automated by fixing it to a linear hydraulic cylinder, air cylinder, motor, etc., and operating it using a control device such as a personal computer or sequencer.

[0060] 9. Post-processing section It is also preferable to provide a predetermined post-treatment section as a next step for treating the resin molded product that has been subjected to deburring, surface modification, and the like by the hybrid flame treatment apparatus. That is, in the post-treatment section, it is usually preferable to carry out a painting process on the surface of the resin molded article that has been subjected to the surface modification treatment, and to carry out an inspection process for the formed coating film. In this case, if the surface of the resin molded product is subjected to a silicate flame treatment or the like, the surface free energy is improved, hydrophilicity is enhanced, antistatic function is exhibited, and adhesion of surrounding dust, dirt, and even low molecular weight substances generated by hybrid flame treatment can be effectively prevented.

[0061] [Second embodiment] The second embodiment is a hybrid flame treatment device in which a first robot arm 22 has multiple robot arms, namely, a 1A robot arm 22a which performs deburring flame treatment on a resin molded product 12, and a 1B robot arm 22b which performs silicate flame treatment, as shown in FIG. As shown in FIG. 8, this embodiment further includes, as part of the hybrid flame treatment device, a fixing device 23 for placing the resin molded product 12 in a predetermined position, a measuring unit for measuring the weight and thickness, and the like. Another embodiment of the hybrid flame treatment device of the present invention will be specifically described below with reference to Figs. 7 and 8 as appropriate. In describing the hybrid flame treatment device in the second embodiment, repeated description of parts that overlap with those of the hybrid flame treatment device described in the first embodiment may be omitted.

[0062] 1. Robot arm No. 1A As shown in FIG. 7, the hybrid flame treatment device of the present invention preferably includes a first robot arm 22a for performing deburring flame treatment as one of a plurality of robot arms in the first robot arm 22. The reason for this is that by providing the 1A robot arm 22a in this manner, the deburring flame treatment and the silicating flame treatment can be performed in-line, thereby further shortening the product cycle time.

[0063] Furthermore, the 1A robot arm can basically be configured in the same manner as in the first embodiment, and it is usually preferable that at least a flame treatment unit having a burner or the like at the tip is attached to a robot arm capable of moving on multiple axes. The reason for this is that, with such a configuration, even in the case of a resin molded product having a complex shape, the flame can be directed toward the burrs from a more efficient direction.

[0064] Furthermore, in the control device of the hybrid flame treatment device of the present invention, the time Ta for the deburring flame treatment of the 1A robot arm is not particularly limited, but is usually preferably set to 90 seconds or less. The reason for this is that by setting the time in this way, in conjunction with the silicic acid flame treatment time in the robot arm of 1B, which will be described later, the robot arm can be operated more efficiently. Therefore, the time Ta for the deburring flame treatment of the 1A robot arm is usually preferably within the range of 1 to 60 seconds, more preferably within the range of 3 to 40 seconds, and even more preferably within the range of 5 to 30 seconds. Here, the control device for the hybrid flame treatment device can be any general control device, and is usually configured with a PC, a microcomputer, a sequencer, and the like.

[0065] 2. Robot arm No. 1B As shown in FIG. 7, the 1B robot arm is preferably one of a plurality of robot arms in the first robot arm 22 and includes a 1B robot arm 22b for performing a silicidation flame treatment. The reason for this is that by providing the 1B robot arm 22b in this manner, the deburring flame treatment and the silicating flame treatment can be performed in-line, thereby further shortening the product cycle time.

[0066] Furthermore, the robot arm of 1B can basically be configured in the same manner as in the first embodiment, and it is usually preferable that at least a flame treatment unit having a burner or the like at its tip is attached to a robot arm capable of moving on multiple axes. The reason for this is that, with such a configuration, even in the case of a resin molded product having a complex shape, the flame can be directed toward the burrs from a more efficient direction.

[0067] Furthermore, since the control device of the hybrid flame treatment apparatus of the present invention essentially eliminates waiting times, etc., it is preferable that the time Tb of the silicate flame treatment by the 1B robot arm is essentially the same as the time Ta of the deburring flame treatment by the 1A robot arm, and is usually set to 90 seconds or less.

[0068] However, it is more preferable that the time Tb for the deburring flame treatment by the 1B robot arm be set so as to satisfy the following formula (1B). Ta / 4≦Tb≦3×Ta (1B) The reason for this is that by setting such a time, the robot arm can be operated more efficiently in conjunction with the deburring flame treatment time of the 1A robot arm.

[0069] Therefore, it is more preferable that the following formula (2B) is satisfied, and it is even more preferable that the following formula (3B) is satisfied. Ta / 3≦Tb≦2×Ta (2B) Ta / 2≦Tb≦1.5×Ta (3B)

[0070] 3. Robot arm of No. 1C The hybrid flame treatment device of the present invention preferably includes a first robot arm 22c, which is one of the multiple robot arms in the first robot arm, as a gate cutting section for removing burrs from the gate portion of a resin molded product removed from the mold molding section. The reason for this is that by having the 1C robot arm 22c in this manner, it is possible to more effectively remove protruding burrs that occur at the entrance (hereinafter sometimes referred to as the gate) through which resin is injected, which is difficult to prevent in manufacturing, such as during injection molding in the mold molding section. Therefore, it is preferable that the robot arm 22c of 1C has the same configuration as that of the first embodiment. On the other hand, unlike the first embodiment, it is also preferable to configure the tip portion to have at least one of a knife blade, saw blade, rotary blade, grinder blade, file, etc. for removing gates, which are protruding burrs. The reason for this is that, with this configuration, relatively large burrs that are difficult to remove by flame treatment can be removed in advance prior to the deburring flame treatment, thereby further shortening the cycle time.

[0071] In addition, the control device of the hybrid flame treatment device of the present invention is preferably set so as to satisfy the following formula (1C) regarding the time Tc of the gate cut processing of the robot arm 1C, although it is not particularly limited thereto. Ta / 8≦Tc≦2×Ta (1C) The reason for this is that by setting such a time, the robot arm can be operated more efficiently in conjunction with the deburring flame treatment time of the 1A robot arm.

[0072] Therefore, it is more preferable that the following formula (2C) is satisfied, and it is even more preferable that the following formula (3C) is satisfied. Ta / 6≦Tc≦1.5×Ta (2C) Ta / 4≦Tc≦Ta (3C)

[0073] 4. Fixtures As shown in FIG. 7, when each treatment of a resin molded product 12 is performed in sequence in the traveling direction D, the hybrid flame treatment device of the present invention preferably has a plurality of fixing devices 23 for placing the resin molded product in a predetermined position along the traveling direction D, either linearly or, although not shown, non-linearly (such as a curved arrangement, a serpentine arrangement, a center pivot arrangement, etc.). Specifically, it is preferable to provide at least a fixture 23a for placing the resin molded product during the deburring flame treatment and a fixture 23b for placing the resin molded product during the silicating flame treatment. The reason for this is that by employing a configuration in which the specified fixing devices 23a and 23b are provided, the location where the flame treatment is to be performed can be specified with high accuracy, and the time required for the flame treatment can be further shortened. Therefore, it is further preferable to provide one or more of the following fixtures: fixture 23c for placing the resin molded product during the gate cutting process, fixture 23d for temporarily placing the resin molded product discharged from the mold molding section, fixture 23e for temporarily placing the resin molded product to be transported to the painting section after the silicate flame treatment, etc.

[0074] Moreover, as shown in Figures 8(a) to (b), it is preferable that the fixing device comprises a main body portion 23w, a protrusion portion 23x that supports the resin molded product 12 above the main body portion 23w, and a lateral columnar portion 23y that supports the resin molded product 12 on the side of the main body portion 23w. The reason for this is that such a configuration makes it possible to reduce the contact area with the resin molded product 12, and more effectively prevents the shape of the resin molded product 12 from changing during each treatment.

[0075] Specifically, as shown in FIG. 8(c), it is preferable that the side columnar portion 23y is configured to move up and down in the Z2 direction in a piston-like manner. The reason for this is that, with such a configuration, the resin molded product 12 can be raised above the protrusions 23x, making it easier to transfer the product to a transport device, which will be described later. Therefore, it is more preferable that the left and right side columnar portions 23y move simultaneously with the same amount of movement.

[0076] Moreover, as shown in FIG. 7, the fixture 23 is preferably provided on an antistatic material 23g in order to prevent static electricity from accumulating on the fixture 23. Specifically, the resistance in the thickness direction measured based on JIS C61340-4-3:2009 is usually set to 1×10 5 ~1×10 14 It is preferable to set the value in the range of 5×10 5 ~1×10 10 It is preferable to set the value in the range of Ω to 1×10 6 ~1×10 8 A value in the range of Ω is even more preferable. The reason for this is that by providing the fixing device on the antistatic material in this manner, it is possible to more effectively prevent static electricity from building up on the resin molded product during processing, and to more effectively prevent dust and the like from adhering to the resin molded product. Therefore, although not specifically shown, it is further preferable that the fixture 23 is provided with an earth member for dissipating static electricity.

[0077] 5. Measurement section It is preferable that the first robot arm is equipped with a load measuring unit that measures the weight of the resin molded product and / or a thickness measuring unit that measures the thickness of the resin molded product as measuring instruments 23z in the measuring unit, as shown in Figure 8(c). The reason for this is that by providing such a measuring section, various flame treatments can be carried out while checking the quality, such as the weight and thickness, of the resin molded product.

[0078] (1) Load measurement section In addition, it is preferable that the first robot arm is equipped with a weight measuring unit. The reason for this is that it is possible to inspect whether the resin molded product is within a preset weight range, thereby making it possible to further improve the yield in the subsequent processes. For example, if a weight measuring unit is provided on the fixture of the 1C robot arm, the weight before and after gate cutting can be measured, making it easier to determine whether the gate cutting was performed properly. Therefore, it is preferable that the load measuring section includes at least one measuring device, for example, a force gauge, a load cell, and a torque meter.

[0079] (2) Thickness measurement unit As another example, it is preferable that the first robot arm includes a thickness measuring unit. The reason for this is that it is possible to inspect whether the resin molded product is within a preset thickness range, thereby making it possible to further improve the yield in the subsequent processes. Furthermore, the heat of the flame treatment can be adjusted according to the thickness of the resin molded product, and the flame treatment can be carried out with greater precision.

[0080] For example, it is preferable that the thickness measuring unit is a contact measuring unit such as a nip-type measuring unit that clamps the thickness direction with two probes and measures the distance between the probes, or an ultrasonic measuring unit that transmits irradiated ultrasonic waves in the thickness direction of the resin molded product and measures the propagation time of the reflected ultrasonic waves. The reason for this is that by providing such a contact measuring unit, the thickness of the resin molded product can be measured more quickly and simply.

[0081] In addition, the thickness measuring unit is preferably a non-contact measuring unit such as a laser measuring unit that irradiates a laser and measures by reading the reflected light, or an electromagnetic induction measuring unit that measures by reading changes in a magnetic field caused by electromagnetic induction. The reason for this is that by providing such a non-contact measuring unit, the thickness of the resin molded product can be measured with greater accuracy and without affecting the resin molded product.

[0082] 6.Transportation equipment Although not shown, the hybrid flame treatment device of the second embodiment preferably includes a transport device for transporting resin molded products between the mold molding section and the first robot arm, between each robot arm in the first robot arm, and between the first robot arm and the downstream painting section. That is, by providing a predetermined transport device, the resin molded products can be transported quickly and smoothly, and the yield rate of the processing in each section can be improved. Specifically, the transport device may be any commonly used transport device, but preferred examples include a crane, a vacuum lifter, a forklift, an AGV, and a conveyor.

[0083] In the hybrid flame treatment device of the present invention, the resin molded product is preferably transported, for example, as follows. That is, as illustrated by symbol F1 in Figure 7, the resin molded product 12 is transported from the mold molding section by a transport device (symbol S1 in Figure 15) and placed on a fixture 23d for temporary storage, temperature control (symbol SA1 in Figure 15), etc. Next, as illustrated by symbol F2, the resin molded product 12 whose surface temperature has reached a predetermined temperature (e.g., 50 to 80°C) is transferred from the fixing device 23d by a conveying device and placed on the fixing device 23c for measurement of weight and thickness (symbol SA2 in Figure 15), gate cutting (symbol SA3 in Figure 15), etc. Next, as illustrated by reference symbol F3, the resin molded product 12 after the gate cut is transferred from the fixture 23c by a conveying device and placed on the fixture 23a for a deburring process (reference symbols S2 and S3 in FIG. 15) or the like. Next, as illustrated by reference symbol F4, the deburred resin molded article 12 is transferred from the fixture 23a by a conveying device and placed on the fixture 23b for a silicic acid flame treatment (reference symbol S4 in FIG. 15) or the like. Next, as illustrated by the symbol F5, the resin molded article 12 that has been subjected to the silicate flame treatment is transferred from the fixture 23b by a conveying device and placed on the fixture 23e for temporary storage before the painting treatment or for predetermined inspection, etc. Then, as illustrated by the reference symbol F6, the inspected resin molded product 12 is removed from the fixture 23e by the conveying device and conveyed to the painting section. The conveyances indicated by the symbols F1 to F6 are preferably performed in reverse order from the latter process side by one conveyance device, but are also preferably performed substantially simultaneously by a plurality of conveyance devices.

[0084] 7. Time required In the hybrid flame treatment device of the second embodiment, even if a gate cut section, a measurement section, etc. are provided, it has been found that the surface temperature of the resin molded product can usually be adjusted to a temperature range of 50 to 80°C by appropriately adjusting the process treatment time of each section, and ultimately, by adjusting the time required for each section. Specifically, the time required for the gate cut section and the time required for the measurement section are each preferably set within a range of 10 to 80 seconds, and more preferably set within a range of 15 to 60 seconds. Therefore, the hybrid flame treatment apparatus of the second embodiment can also easily perform hybrid flame treatment on a resin molded product maintained at a predetermined temperature (for example, 50 to 80° C.).

[0085] In the hybrid flame treatment device of the present invention, it is preferable that the transfer times for the resin molded products, indicated by the reference characters F1 to F6 in FIG. 7, are each within 20 seconds. The reason for this is that by transporting the resin molded article for such a time, the resin molded article can be transported without the surface temperature being lowered excessively, and each treatment can be carried out more efficiently. Therefore, the conveying time of the resin molded article is preferably within the range of 1 to 20 seconds, more preferably within the range of 3 to 15 seconds, and further preferably within the range of 5 to 10 seconds.

[0086] 8.Temperature control section In the hybrid flame treatment device of the second embodiment, even if a gate cut section, a measurement section, etc. are provided, it is preferable to appropriately adjust the process treatment time of each section so that the surface temperature of the resin molded product becomes the desired value. Therefore, although not shown, it is preferable to provide a temperature control unit to detect and control the temperature. Therefore, even in the apparatus for producing resin molded products according to the second embodiment, if the surface temperature of the resin molded product (e.g., 50 to 80°C) exceeds a predetermined range, it is preferable to use a specified apparatus (not shown) to carry out heating treatment or cooling treatment (including natural cooling) to appropriately adjust the temperature. Specifically, as shown in FIG. 7, it is preferable that the resin molded product 12 transported from the mold molding section is temporarily placed on a fixture 23d, and then heated or cooled using a heater, a blower, or the like.

[0087] [Third embodiment] As shown in FIG. 9, the third embodiment is a hybrid flame treatment device including a first robot arm 22 and a fixture 23 according to the second embodiment. The present embodiment further includes a moving device that moves the resin molded product placed on the fixture in the vertical and horizontal directions and passes it on to another fixture, and a rotating device that changes the orientation of the resin molded product placed on the fixture. Furthermore, it is preferable to provide a measuring unit for measuring the weight and thickness of the resin molded product, and a printer for printing a lot number, etc. on the processed resin molded product.

[0088] 1. First robot arm As shown in FIG. 9, the hybrid flame treatment apparatus preferably has, as the first robot arm 22, a 1A' robot arm 22a' that performs deburring flame treatment and a 1B' robot arm 22b' that performs silication flame treatment. The reason for this is that the first robot arm has two robot arms, so that the deburring flame treatment and the silicification flame treatment can be performed continuously, and the occurrence of condensation during the treatment can be more effectively suppressed, which in turn shortens the cycle time of the product in the hybrid flame treatment device.

[0089] Here, it is preferable that the robot arm 1A' basically has the same configuration as in the first and second embodiments. Furthermore, as shown in FIG. 10, it is also preferable that the 1A' robot arm 22a' is equipped with a flame treatment section such as a burner 18a that can remove gates and burrs, and a cutting treatment section such as a knife blade 18e, in addition to the deburring flame treatment section. The reason for this is that by having both a flame treatment section and a cutting treatment section, the cutting marks can be removed more quickly in the flame treatment section after relatively large burrs are cut off from the plastic molded products transported from the mold molding section.

[0090] Also, as shown in FIG. 10, it is preferable that the 1A' robot arm 22a' is configured to switch between the flame treatment section and the cutting treatment section by moving the knife blade 18e of the cutting treatment section and the like in and out of the storage area 18f for the knife blade 18e. The reason for this is that by being able to switch between the processing sections, the same robot arm can perform gate processing and deburring processing without any time gap, making it possible to carry out the specified processing more quickly. Furthermore, this effectively prevents one of the two from interfering with the resin molded product while the other is being treated, and allows the specified flame treatment to be carried out with greater precision.

[0091] The shape of the knife blade storage area is preferably plate-like so as to cover one side of the knife blade. The reason for this is that by using such a shape, the hand portion of the robot arm can be made smaller. Specifically, therefore, it is preferable that a slide member be provided along the storage area for the knife blade, and that the knife blade be provided via the slide member. On the other hand, it is also preferable that the shape of the knife blade storage area is box-shaped so as to cover the entire knife blade. In this case, it is preferable to provide a window through which the knife blade can be inserted and removed, and it is also preferable to provide a slit in the side of the box through which the knife blade can be inserted and removed.

[0092] Moreover, as one example, the 1A' robot arm is preferably configured to slide a knife blade of the cutting processing section in the longitudinal direction. Furthermore, as another example, it is also preferable that the 1A' robot arm is configured to rotate the knife blade of the cutting processing section around the base of the knife blade to extend or retract it.

[0093] Moreover, it is preferable that the robot arm 22b' of 1B' basically has the same configuration as that of the first and second embodiments. Furthermore, it is preferable that the 1B' robot arm is configured to switch between the silicate flame treatment and the normal flame treatment. The reason for this is that by being able to switch the type of treatment, when the silicate flame treatment on a resin molded product is completed, normal flame treatment can be carried out on another resin molded product placed on the previous fixture. Furthermore, even if there is a time difference between the deburring flame treatment and the silicating flame treatment, the time difference can be reduced, thereby further reducing the cycle time of the hybrid flame treatment device.

[0094] 2.Mobility Device As shown in FIG. 9, the hybrid flame treatment device preferably includes a transfer device 25 for transferring the resin molded article 12 placed on a fixture 23 to another fixture 23. In other words, it is preferable that the moving device is configured to move in sequence between a first fixing device for placing the resin molded product removed from the mold molding section, a second fixing device for performing the burr removal flame treatment, a third fixing device for performing the silicate flame treatment, and a fourth fixing device for placing the resin molded product after the silicate flame treatment is completed, and to transfer the resin molded product placed on each fixing device onto another fixing device. The reason for this is that by being equipped with such a moving device, the first robot arm does not need to transport the resin molded product, and the deburring flame treatment and the silicating flame treatment can be performed more efficiently and quickly. Therefore, as shown in Figure 9, it is preferable that the moving device 25 has a guide rail 23v that is aligned with the traveling direction D of the resin molded product 12, a support arm 23y' that moves along the guide rail 23v, and a drive unit 25c that operates the support arm 23y'. The drive unit preferably includes a motor or the like.

[0095] Here, the guide rail is not particularly limited, but is usually preferably composed of a linear guide and a block that fits onto the linear guide via a plurality of ball bearings. Specifically, the guide rail preferably comprises a square rod-shaped linear guide and a gate-shaped block disposed so as to straddle the linear guide. The reason for this is that with such a configuration, friction between the linear guide and the block can be reduced, allowing the moving device to operate more quickly and accurately. On the other hand, as another embodiment of the guide rail, it is also preferable that the guide rail is composed of a round bar-shaped linear guide and a cylindrical block provided so that the linear guide passes through the block.

[0096] It is also preferable that two or more guide rails are provided vertically below the support arm and in parallel. The reason for this is that by providing two or more guide rails, it is possible to more effectively reduce lateral shaking of the support arm when it slides. Therefore, it is preferable that two to six guide rails, and more preferably three to five guide rails, are provided vertically below the support arm in parallel. When support arms are provided on both sides of the fixture, it is preferable to provide two or more guide rails for each support arm.

[0097] Moreover, it is preferable that the support arm is connected to the guide rail at its lower vertical end and is extendable and contractable along the vertical direction. The reason for this is that the expandable support arm allows the resin molded product placed on the fixture to be lifted up and moved to the next fixture, and therefore the resin molded product can be delivered more quickly.

[0098] Moreover, it is preferable that the support arms are disposed so as to sandwich the fixture in a direction perpendicular to the traveling direction of the resin molded product. The reason for this is that such an arrangement allows the resin molded product to be lifted from both sides, making it possible to move it more stably.

[0099] It is also preferable that the support arms are provided at a plurality of locations along the direction in which the resin molded product travels. The reason for this is that by having multiple support arms, multiple resin molded products placed on each fixture can be transferred to the next fixture simultaneously, thereby further reducing the cycle time of the hybrid flame treatment device.

[0100] Specifically, it is preferable that the number of support arms provided is one less than the number of fixing devices. The reason for this is that when the leading resin molded product in the direction of travel of the resin molded products is transported out, all other resin molded products can be handed over to the next fixing device together, thereby further reducing the cycle time of the hybrid flame treatment device. Therefore, for example, when there are first to fourth fixing devices, it is preferable that the support arm is provided at three locations corresponding to the first to third fixing devices.

[0101] Moreover, as shown in FIG. 12(b), it is preferable that the support arm 23y' is provided at its vertically upper end with a frame-like support member that conforms to the shape of the contact portion of the resin molded product. The reason for this is that the provision of the support member makes it possible to prevent the resin molded product from losing balance and falling when it is being moved, thereby enabling it to be operated at a higher speed. Therefore, it is preferable to connect the support arm and the support member by screwing, fitting, or the like so that the support member can be replaced in accordance with the type of resin molded product.

[0102] Moreover, as shown in FIG. 14, it is preferable that the moving device 25 includes, along the traveling direction, a rack 25a fixed to the support arm 23y', a pinion gear 25b engaging with the rack 25a, and a drive unit 25c for rotating the pinion gear 25b. The reason for this is that, with such a configuration, it is possible to move a plurality of support arms arranged on a linear guide more quickly and with greater precision. Therefore, it is preferable to link a plurality of support arms arranged along the traveling direction of the resin molded product by using a single rack to interlock the support arms.

[0103] Although not specifically shown, it is also preferable that the moving device is provided with a chain connected to the support arm and extending along the moving direction, and a motor for rotating the chain, etc. The reason for this is that, with such a configuration, the support arm can be moved with a simpler configuration.

[0104] 3. Rotating device As shown in FIG. 11, the hybrid flame treatment apparatus preferably includes a rotation device 23m for changing the orientation of the resin molded article 12 placed on the second fixture 23a' or the third fixture 23b'. The reason for this is that by providing a rotation device, the first robot arm can process both sides (side A and side B) without going around the resin molded product, making it possible to perform deburring and flame silicidation treatment more quickly.

[0105] Moreover, as shown in FIG. 11, it is preferable that the rotation device 23m includes an actuator 23h for linear motion, a rack 23k that moves linearly in response to the motion of the actuator 23h, and a turntable that fits into the rack 23k and rotates. The reason for this is that with such a configuration, the resin molded product placed on the turntable can be rotated more stably, and adjustments such as the rotation angle can be made with greater precision.

[0106] Moreover, as shown in FIG. 14, the rotation device preferably rotates the angle of the resin molded product by 10 to 360° along a horizontal plane. The reason for this is that by rotating the resin molded product, the robot arm 22a' of 1A' and the robot arm 22b' of 1B' can process the same resin molded product at the same time. Therefore, the rotation device preferably rotates the angle of the resin molded article along the horizontal plane by 20 to 270°, and more preferably by 30 to 180°.

[0107] 4. Measurement section The hybrid flame treatment device preferably includes a measuring unit for measuring the weight and thickness of the resin molded product. The reason for this is that the provision of a measuring section makes it possible to carry out various flame treatments while checking the quality of the resin molded product, such as its weight and thickness. Specifically, as shown in Figures 12(a) to (b), it is preferable that the measurement unit includes a load measuring instrument 23z, an elevator 23s that lifts the resin molded product 12 off the fourth fixing device 23e' when measuring the weight of the resin molded product 12, and a base 23p that stabilizes the resin molded product 12 on the load measuring instrument.

[0108] 5.Printing device As shown in FIG. 13, the hybrid flame treatment apparatus preferably includes a printer 23t for printing a lot number and the like on the treated resin molded article 12. The reason for this is that by printing a lot number or the like on a resin molded product, it is possible to check the manufacturing time, manufacturing location, manufacturing equipment, and the like after production, thereby improving traceability.

[0109] In addition, although there is no particular limitation on the printing device, it is preferable to use a laser or the like to inscribe information such as the lot number, manufacturing date and time, manufacturing location, and manufacturing equipment on the back surface of the end portion along the width direction of the resin molded product. The reason for this is that laser marking makes it possible to control quality over the long term without the marking fading later. Therefore, the printing device is preferably a laser irradiation device using a carbon laser, since this can be applied to a variety of materials.

[0110] [Fourth embodiment] The fourth embodiment is a hybrid flame treatment method in which a resin molded product having burrs and a predetermined surface temperature (at least 50°C or higher) is subjected to a deburring flame treatment and a silicating flame treatment by at least one flame treatment unit, and is characterized by including the following steps (1) and (2). (1) A gripping process in which a plastic molded product is moved and held by a gripping device. (2) A hybrid deburring process in which a resin molded product held by a gripping device is subjected to a deburring flame treatment and a silicating flame treatment by at least one flame treatment section. Hereinafter, the hybrid flame treatment method according to the fourth embodiment will be specifically described with reference to the production flow chart shown in FIG. In addition, when explaining the hybrid flame treatment method in the fourth embodiment, the hybrid flame treatment apparatus described in the first to third embodiments can be used, so repeated explanations of overlapping parts may be omitted as appropriate.

[0111] 1.Removal process As shown as S1 in FIG. 15, it is preferable to provide an unloading step before starting to use the hybrid flame treatment device, thereby having a step of unloading the device from the mold forming section. It is also preferable that the method includes a preparatory step of cleaning the surface of the resin molded article having burrs by air washing or subjecting the surface to a uniform treatment. The reason for this is that if a release agent or the like is attached to the surface of the resin molded product, the fixation of the resin molded product may decrease, or the efficiency of deburring the resin molded product may decrease.

[0112] In order to further improve the efficiency of the hybrid flame treatment of the resin molded article, it is preferable to keep the temperature of the resin molded article within a predetermined range and to keep the temperature variation constant. More specifically, the surface temperature of a resin molded product immediately after removal from the mold is usually 100 to 120°C, but it has been found that the surface temperature can usually be adjusted to a temperature range of 50 to 80°C if the elapsed time is within 5 minutes. Therefore, as shown in FIG. 17(a), the time T1 required for S1 is, for example, about 10 seconds.

[0113] On the other hand, it has been found that if the surface temperature of the resin molded product is 50 to 80°C, the surface modification effect of the hybrid flame treatment is further improved and there is little variation in the surface modification effect. Conversely, if the surface temperature of the resin molded product is less than 50°C, the hardness of the resin molded product may increase, resulting in insufficient deburring flame treatment, or the surface modification by the silicating flame may become uneven. On the other hand, if the surface temperature of the resin molded product exceeds 80° C., it may become prone to partial deformation during transportation.

[0114] Therefore, when carrying out the hybrid flame treatment, it is preferable that the surface temperature of the resin molded product be in the range of 50 to 80°C with a temperature variation of ±20°C, and it is more preferable that it be ±10°C. That is, it is more preferable to monitor the surface temperature of the resin molded product with a non-contact infrared thermometer or the like, and to confirm that the surface temperature is within a predetermined temperature range and the degree of variation before carrying out the hybrid flame treatment.

[0115] 2. Delivery process Next, as shown in Figures 1 and 2, it is preferable to have a process in which the resin molded product having burrs on the peripheral edge, which has been molded in the mold molding section 30, is held by a second robot arm as a gripping device and transported to the hybrid flame treatment device via the transport path 32.

[0116] Furthermore, although not shown, it is preferable to carry out a temporary fixing step, in which the resin molded product having burrs on its peripheral edge and at a predetermined surface temperature, which has been removed from the mold molding section (mold molding machine), is temporarily fixed onto a frame-shaped temporary fixing tool via a suction device. That is, the process of temporarily fixing a resin molded product is a process of holding the resin molded product in a predetermined position on a temporary fixture using a predetermined temporary fixing device (suction device).

[0117] 3. Hybrid flame treatment process Next, a hybrid flame treatment process is carried out, and as shown in FIG. 15 as S2 to S3, it is preferable that a burner provided at the tip of a robot arm sprays a silicate flame along the edge and some of the side surfaces of the overall shape of the resin molded product, and against the burrs of the resin molded product having both side surfaces (side A and side B). That is, it is preferable to start the hybrid flame treatment device 10, and further operate the flame source and the first robot arm 22 to spray a silicate flame from the burner in the flame treatment device 18 to the burr portion of the resin molded product 12, with the flame having a flame temperature of approximately 800°C and a flame length of approximately 5 to 40 mm, and to scan the burner along the peripheral portion (sides A and B) of the resin molded product 12 via the control device 26. In this way, it is preferable to remove burrs from the resin molded product and to carry out a surface modification treatment practically at the same time to make the surface more adhesive. Therefore, as shown in FIG. 17(a), the times T2 and T3 required for steps S2 and S3 are, for example, about 15 seconds each.

[0118] Next, as shown as S4 in FIG. 15, a burner provided at the tip of the robot arm is preferably used to spray a silicate flame along the surface (C surface) of the resin molded product to modify the surface of the resin molded product and to provide an easily adhesive surface for the main surface on which the coating film is formed. That is, it is preferable to eject the silicic acid flame while scanning along the main surface (C surface) of the resin molded article 12 on which the coating film is formed and which serves as the decorative surface. Therefore, as shown in FIG. 17(a), the time T4 required in step S4 is, for example, about 20 seconds.

[0119] In the hybrid flame treatment device 10, it is preferable to eject a silicate flame from a burner in the flame treatment device 18 over a width of 1 to 1.5 mm from the edge of the resin molded product 12, that is, over a width of 1 to 1.5 mm to match the width of any burrs remaining on the resin molded product 12.

[0120] 4. Switching process Next, although not shown, it is preferable to provide a switching step for switching between a silicic acid flame and a normal flame treatment (sometimes referred to as a non-silicic acid flame) in steps S2 and S3, respectively. More specifically, in areas where there are certain burrs, such as at the edges of the resin molded product 12, it is usually preferable to spray a silicic acid flame in order to perform hybrid flame treatment.

[0121] On the other hand, in the case of a resin molded product in which the predetermined burr is small and there is little need to perform a surface modification treatment due to the resin material, it is also preferable to switch the raw material gas using a switching device and spray a non-silicic acid flame. That is, it is also preferable to provide a switching step in which the emission of a predetermined silicating flame and the emission of a non-silicicating flame are switched to optimize the consumption amount of the surface modifier.

[0122] For example, in steps S2 and S3, when the burrs are relatively small and the number of burrs is small, it is preferable to carry out only the silicate flame treatment to remove the burrs and to carry out the surface modification treatment. On the other hand, in steps S2 and S3, for resin molded products having a considerable number of relatively large burrs, it is preferable to first carry out normal flame treatment, i.e., non-silicic acid flame treatment, for a predetermined period of time, and then carry out a switching step so that the silicaic acid flame treatment can be carried out for a predetermined period of time.

[0123] 5. Attachment and removal process Next, although not shown, the attachment / detachment process is a process in which the resin molded product that has been subjected to the deburring flame treatment and the silicate flame treatment is removed by hybrid flame treatment, while the resin molded product to be treated next is fixed in place. More specifically, when attaching a resin molded product having burrs, the deburring device can be fixed to the attachment / detachment area, allowing the work to be performed quickly.

[0124] On the other hand, when hybrid flame treatment is to be performed on a resin molded product, the hybrid flame treatment deburring device can be moved to the treatment area to perform the treatment quickly and safely. That is, the attachment / detachment step is a step of attaching and detaching the resin molded product before the hybrid flame treatment and the resin molded product after the hybrid flame treatment, respectively. The mounting and dismounting process can be carried out sufficiently by human power, but it is also preferable to use a robot arm or the like to further increase the efficiency of the work.

[0125] 6.Painting process Next, as shown as S5 in FIG. 15, it is preferable to carry out a painting process on the resin molded article that has been subjected to the hybrid flame treatment. That is, it is usually preferable to carry out the painting process by transporting the resin molded product that has been subjected to the hybrid flame treatment to a painting booth, where a predetermined paint (such as a water-based paint) is sprayed onto the product using a spray gun or the like. Therefore, as shown in FIG. 17(a), the time T5 required for step S5 is, for example, about 10 minutes.

[0126] In addition, in the manufacturing flow (S1' to S6') of resin molded products before hybrid flame treatment and conventional flame treated products as shown in Figure 15, due to the nature of resin molded products (polypropylene resin, etc.), they are extremely prone to becoming electrostatically charged. Therefore, surrounding dust and other particles are easily attracted to them, and this is sometimes found as foreign matter after painting treatment. However, in the case of resin molded products after hybrid flame treatment, the surface volume resistivity is usually 1×10 8 ~1×10 12 It can be adjusted to a value in the range of Ω·cm. Therefore, antistatic treatment, which makes the material less likely to become charged, can be performed simultaneously with adhesion-improving treatment.

[0127] Therefore, even if dust or the like adheres to the coating surface, it is easily removed by the air spray, and the effect is that very little foreign matter is observed after the coating process. Of course, since the resin molded product after the hybrid flame treatment has an easily adhesive surface, when a specified paint (such as a water-based paint) is sprayed onto it, it will remain effectively, and after forming a coating, it will exhibit strong and smooth properties.

[0128] Moreover, in the manufacturing flow (S1' to S6') of resin molded products before hybrid flame treatment and conventional flame treated products as shown in Figure 16, it was common to have a cooling process (S2') in which the resin molded product is left to stand for a long period of time after being removed from the mold, at least until it reaches near room temperature. As a result, since surface temperature changes as shown in Figure 17(b) are expected in each of steps S1' to S6', problems such as insufficient or uneven deburring flame treatment and silicating flame treatment in steps S3' to S5', and ultimately large variations in the adhesion of the coating film formed in the painting step represented by S6' and difficulty in forming a smooth coating film, were observed. Furthermore, among the times T1' to T6' required for steps S1' to S6', the time T2' is, for example, about 10 minutes.

[0129] In contrast, in the case of the present invention, since surface temperature changes as shown in FIG. 17(a) are expected in each step S1 to S5, hybrid flame treatment can be performed on a resin molded product maintained at a predetermined temperature (e.g., 50 to 80°C). Therefore, due to the nature of the molding resin, at a given temperature, the temperature is maintained at least 50°C higher than the glass transition temperature (e.g., 0°C), so the molding resin easily softens and the deburring process can be carried out easily and quickly.

[0130] In addition, since the surface temperature of the resin molded product is maintained at a predetermined temperature, the siliconizing flame containing the silicon-containing compound effectively modifies the surface, the surface modification effect is more reliably improved, and processing unevenness is reduced. This has the advantage that the adhesion of the coating film formed in the coating step S5 is stabilized and a smooth coating film can be easily formed.

[0131] 7.Inspection process Therefore, as described above, the resin molded product having a coating film formed by the hybrid flame treatment not only has no burrs, but also has extremely little foreign matter mixed in with the coating film formed on the surface of the resin molded product, and can exhibit the effect of having strong adhesion of the coating film formed in the cross-cut test in accordance with JIS-K5600. In other words, in the inspection process, the number of defective products due to burrs, foreign matter contamination, etc. is greatly reduced, and the adhesion of the coating film is significantly improved, improving the yield of resin molded products with coating films, and increasing the economic benefit.

[0132] For example, when the surface temperature of a resin molded product (PP resin plate) is 20°C, the number of foreign bodies (diameter 0.1 to 100 μm) in the coating film formed on the surface by a specified silicate flame treatment was approximately 8 per 100 resin molded products on which the coating film was formed, as a result of optical microscope inspection, and the number of peeled grids in a cross-cut test was an average of 10 grids per 100. Furthermore, when the surface temperature was 40°C, the number of foreign bodies in the coating film formed on the surface was approximately 6 per 100 resin molded products on which the coating film was formed, and the number of peeled grids in the cross-cut test was an average of 6 per 100 grids.

[0133] However, when the surface temperature was 50°C, the number of foreign bodies in the coating film formed on the surface rapidly decreased to about 2 per 100 resin molded products, and it was confirmed that the number of peeled off grids in the cross-cut test was an average of 2 per 100 grids. Furthermore, when the surface temperature was 80°C, the number of foreign bodies in the coating film formed on the surface was 0 per 100 resin molded products, meaning that no specified foreign bodies were observed at all, and it was confirmed that the number of peeled grids in a cross-cut test was an average of 1 or less per 100 grids.

[0134] 8.Other processes (1) Temperature control process As shown by symbol SA1 in Figure 15, the hybrid flame treatment method of the present invention preferably includes, as another process, a temperature control process for adjusting the surface temperature (e.g., 50 to 80°C) of the resin molded product transported from the mold molding section. The reason for this is that by controlling the temperature in this manner, the hardness of the resin molded product can be adjusted, improving the accuracy of gate cutting and deburring processes, and the temperature can be more easily adjusted to a level at which uneven painting is less likely to occur.

[0135] (2) Measurement process As shown in FIG. 15 and designated by reference symbol SA2, the hybrid flame treatment method of the present invention preferably includes, as another step, a measurement step of measuring the weight and / or thickness of the resin molded article. The reason for this is that by carrying out measurements in this manner, the quality of the resin molded product, such as its weight and thickness, can be confirmed, and the degree of subsequent processing can be appropriately adjusted.

[0136] (3) As shown in FIG. 15 and designated by symbol SA3, the hybrid flame treatment method of the present invention preferably includes, as another step, a gate cutting step of removing burrs from the gate portion of the resin molded product removed from the mold molding section. The reason for this is that by cutting the gate in this manner, it is possible to more effectively remove protruding burrs that occur at the gate during injection molding, which are difficult to prevent in the manufacturing process. [Industrial Applicability]

[0137] As described above in detail, the hybrid flame treatment apparatus and hybrid flame treatment method of the present invention include a gripping device for holding a resin molded product having a burr and a surface temperature of at least 50°C or more in a predetermined position, and a first robot arm equipped with at least one flame treatment device for performing hybrid flame treatment on a resin molded product having a surface temperature of 50°C or more. By performing hybrid flame treatment, it is possible to perform deburring flame treatment on the resin molded product and also perform a silicate flame treatment, which effectively improves the surface free energy and enables a stable exertion of a good surface modification effect.

[0138] Therefore, according to the hybrid flame treatment apparatus and hybrid flame treatment deburring flame treatment method of the present invention, even when applied to large plastic molded products such as bumpers, which are automobile parts, a cooling process to room temperature is virtually unnecessary, so that deburring treatment and silicate flame treatment can be performed effectively in an extremely short time.

[0139] Furthermore, according to the hybrid flame treatment apparatus and hybrid flame treatment method of the present invention, it is expected that the antistatic effect based on the silicate flame treatment will effectively prevent foreign matter such as dust from being charged and adhering to the surface of a resin molded product. Furthermore, even if the fuel source contains a material that generates water as a result of combustion, such as alcohol, the present invention can be used to paint without lowering the temperature to room temperature, and condensation is unlikely to occur, so it is expected that uneven processing caused by condensation on the surface can be effectively prevented. Furthermore, by using a burner with other surface modification effects in addition to the burner used for deburring and silicate flame treatment in the first robot arm, it is expected that a better surface modification effect can be achieved and the processing time can be shortened. Specifically, as an example, the use of a hydrogen burner is expected to significantly reduce carbon dioxide emissions when the burner is in use and to improve the flame blow-out speed, thereby enabling more rapid surface treatment. This makes it possible to significantly improve the yield after the next process, which is the formation of a coating film on a resin molded product. Furthermore, by replacing the burners used in the deburring and silicate flame treatment with hydrogen burners or the like, it is expected that carbon dioxide emissions can be further reduced, thereby mitigating the impact on the environment.
