Description

  The present invention relates to an apparatus for determining whether or not an adhesive application condition is satisfied in an adhesive application step, and in particular, from a substrate weight before applying an adhesive and a substrate weight after applying, The present invention relates to an apparatus for calculating the weight of applied adhesive and determining whether or not a predetermined amount of adhesive is applied.

  In the process of applying the adhesive, as a device for satisfying the application condition of the adhesive, the form for controlling the state when spraying the liquid adhesive and the weight before and after applying the adhesive are measured to determine pass / fail There was a form to do.

  In the conventional technology for controlling the spray state, the state of the adhesive applied to the object to be applied by the application nozzle (spray gun) is substantially circular. There is one that measures and calculates the application amount by the application form and its weight, and controls the discharge time for satisfying the application condition based on these data (see Patent Document 1).

  On the other hand, in the conventional technique of comparing the weight before and after the adhesive application, a work (application object) is mounted on the weight measurement unit, the adhesive is applied to the work, and the weight measurement unit There is one that obtains the coating amount from the weight difference by measuring the weight before and after coating (see Patent Document 2).

JP-A-9-206647 JP-A-8-108123

  The invention disclosed in Patent Document 1 corrects the discharge time discharged from the coating nozzle as appropriate, and the discharge time is corrected during the coating process. And the application | coating time after correction | amendment was set as new discharge time, and the application | coating conditions were satisfy | filled by controlling the discharge time after that.

  However, the above apparatus does not determine whether or not the coating condition is satisfied. That is, by controlling the discharge time, it can be theoretically assumed that a predetermined weight of the adhesive is applied, but it was not clear whether the adhesive was applied according to the theory.

  On the other hand, in the invention disclosed in Patent Document 2, the weight measuring unit measures the weight of the workpiece before the adhesive is sprayed from the adhesive spray nozzle (spray gun), stores this, and further stores the same weight. The measuring unit measures the weight of the workpiece after the adhesive is injected, and determines pass / fail by the difference.

  However, the works that can use the above technique are limited. That is, since the workpiece is mounted on the weight measuring unit, when the adhesive sprayed from the adhesive spray nozzle deviates from the workpiece application surface and adheres to the weight measuring unit, the weight measuring unit satisfies a predetermined condition. This is because there is a possibility that it is determined that a sufficient amount of adhesive has been applied. Therefore, it can be used when, for example, an adhesive is applied to the inner surface portion of a box-shaped workpiece, but the adhesive may be sprayed out of the workpiece like the surface of a plate-like member. It was unsuitable.

  In addition, both of the above techniques are intended to satisfy the application conditions in the application process or immediately after the application. However, when a solvent-type adhesive is used, a process for volatilizing the solvent is required. Therefore, the amount to be actually applied as an adhesive should be judged by the state after the solvent has been volatilized. However, when using both of the above-mentioned techniques, when a solvent-type adhesive is used, the final application amount of the adhesive has to be an expected value.

  The present invention has been made in view of the above points, and its object is to determine whether or not the substantial amount of adhesive when applying a solvent-type adhesive satisfies the application condition. It is to provide an apparatus that can.

  In view of this, the present invention provides an adhesive comprising: a step of applying a solvent-type adhesive to a substrate by a spray gun; and a step of volatilizing a solvent portion of the solvent-type adhesive by a solvent volatilizing portion. A device for determining the amount of adhesive applied in the coating process, wherein a pre-weighing means for measuring the weight of the base material before applying the solvent-type adhesive, and the base material has been taken out from the pre-weighing means A weighted detection means, a first giving means for giving the order of the base materials when detecting the removal of the base material from the pre-weighing means, and the base material weighed by the pre-weighing means A pre-information storage unit for storing the pre-weight and the order applied by the first applying unit, a post-measuring unit for measuring the weight of the substrate discharged from the solvent volatilizing unit, and the post-measuring unit The order for the substrate to be measured The second application means to be applied, and the pre-weight of the base in the same order as the order given by the second application means, and the actual weight of the adhesive is calculated from the pre-weight and the post-weight, and the real A weight determination unit that compares the weight with the application condition to determine whether it is correct or not, and a notification unit that notifies that the condition is not satisfied when the determination result by the weight determination unit does not satisfy the application condition of the adhesive. It is a feature.

  According to the above configuration, the substantial weight of the adhesive can be calculated by comparing the preliminary weight of the base material measured by the preliminary weighing unit with the posterior weight of the same base material. The substantial adhesive weight is determined by the weight determination means as to whether or not the application condition of the adhesive is satisfied, and is notified of the unfulfilled condition. In addition, since the order of the base materials applied by the first applying means and the order of the base materials applied by the second applying means are the same order, the application of the solvent adhesive is next. In addition, even when going through a solvent volatilization step, weight comparison can be made for the same substrate.

  According to the present invention, it is possible to determine whether or not the substantial amount of adhesive when applying the solvent-type adhesive satisfies the application condition. Moreover, it can pass through a solvent volatilization process and can be used in the application | coating process of a solvent form adhesive agent.

  Furthermore, according to the configuration provided with the supply detection means and the discharge detection means in the solvent volatilization part, the identity of the order of the base materials put into the solvent volatilization part and the order of the removed base materials is maintained. Thus, the order of the base materials is not confused by the base material being charged into the solvent volatilization section. Since the first and second determining means and the notifying means are provided, when the taken out order is different, it is notified, and it is possible to avoid comparing the weights of the substrates in different orders.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Since the present invention is used in the solvent-type adhesive coating process, the solvent-type adhesive coating process will be described first.

  FIG. 1A is a general process diagram showing a coating process of a solvent-type adhesive. As shown in this figure, first, a substrate to which a solvent-type adhesive is to be applied is placed in the application area. The application area is a place for spraying the solvent-type adhesive on the portion of the substrate surface to be applied (hereinafter referred to as the application surface) by a spray device that can spray the solvent-type adhesive (so-called spray gun). Thus, it is possible to prevent the solvent-type adhesive sprayed from the spray gun from splashing out of the area when it deviates from the edge of the application surface. The application area is provided with a support part that supports the back side of the base material, and the support part supports the back side of the base material so that the application surface faces the spray gun spray port. Can do.

  Subsequently, a solvent type adhesive is applied to the application surface with a spray gun. The type of the solvent-type adhesive sprayed from the spray gun varies depending on the base material and the material of the object to be bonded, but generally, the adhesive component is melted in a solvent. When the solvent is an organic solvent, it is called an organic solvent-type adhesive. Depending on the main component of the adhesive, rubber-based organic solvent-type adhesives, vinyl acetate-based organic solvent-type adhesives, urethane-based organic solvent-type adhesives, etc. There is. In the present invention, these various organic solvent-type adhesives are collectively referred to as solvent-type adhesives.

  In addition, the application process using a spray gun may be manually controlled by an operator in addition to being automatically controlled. In the case of automatic control, the angle at which the spray gun spray port should be directed to the coating surface and the distance from the coating surface are controlled, and the spraying time is controlled so that a predetermined amount of solvent-type adhesive is placed at a predetermined position. It is something to apply. However, in the case of spraying by automatic control, it is difficult to finely adjust the sprayed state of the solvent-type adhesive, and thus the solvent-type adhesive on the coated surface may be shaded. Therefore, in order to apply the solvent-type adhesive evenly, the operator dares to manually operate the spray gun.

  In any case, after applying the solvent-type adhesive to the entire predetermined application surface, the base material is taken out from the application area, and the process proceeds to the next step. The base material is taken out by releasing the back side support by the support portion of the application area.

  Next, the base material taken out from the application area is supplied to the solvent volatilization section. The solvent volatilization part is maintained at a predetermined temperature, and the solvent is volatilized by being left in the solvent volatilization part for several minutes. The set temperature in the solvent volatilization portion varies depending on the type of the solvent to be volatilized, and the required time varies depending on the solvent content and the like, and therefore is appropriately adjusted depending on the solvent-type adhesive used. By volatilizing the solvent, it is possible to leave only the adhesive component on the coated surface of the base material, and the base material is taken out from the solvent volatilizing portion and supplied to the subsequent bonding step. In addition, an adhesion process is a process of bonding the material which should be adhere | attached on an application surface, and only the base material which satisfy | fills the application | coating conditions of an adhesive agent is supplied to the said adhesion process.

  As described above, since the solvent-type adhesive is applied to the base material, and then the solvent is volatilized, only the adhesive remains on the application surface, so that the adhesive application state remains on the base material. It is judged by the weight of the adhesive component. Specifically, as shown in FIG. 1 (b), the weight of the substrate before applying the solvent-type adhesive is measured, and after the application process is finished (after application of the solvent-type adhesive and volatilization of the solvent) In this case, the substantial weight of the adhesive is calculated by measuring the weight of the entire base material. On the other hand, the partial unevenness of the adhesive applied to the application surface is judged by visual observation, but by mixing a colorant with the adhesive, it can be judged by the color shade of the colorant.

  In addition, even if it is a case where a base material is the same shape, all the weights of the base material before application | coating cannot be assumed. This is because the error in weight when manufacturing the base material is greatly different from the weight of the adhesive. That is, for example, when the base material is a plastic molded product, the weight of about several grams easily differs depending on the density of the plastic resin that has flowed into the molding die. Therefore, when applying several g of adhesive, it is important to measure the weight before application.

  By the way, in the solvent-type adhesive coating process, the solvent-type adhesive is partially sprayed by a spray gun, but the solvent-type adhesive is applied to the entire coating surface by sequentially moving the spraying position according to a predetermined order. Is applied. It is well known that when a solvent-type adhesive is sprayed by a spray gun, the mist-like diffusion state varies depending on the distance from the spray gun spray port. Therefore, the solvent-type adhesive does not diffuse much in the vicinity of the injection port, and the thick solvent-type adhesive is sprayed on a small area, but the solvent-type adhesive greatly diffuses at a position away from the injection port. For this reason, it is sprayed thinly over a large area. Furthermore, the density of the sprayed state varies depending on the state of the nozzle of the injection port. In other words, the nozzle at the spout has an infinite number of fine holes, but when this fine hole is closed by hardening of an adhesive or the like, it is ejected from a fine hole with a small amount of solvent-type adhesive to be ejected. As a result, the solvent-type adhesive to be ejected may be ejected in an uneven amount, or may be in a deep spray state despite being away from the ejection port. Under such circumstances, the state of the applied solvent-type adhesive is judged, and when it is sprayed deeply, fine adjustment such as separating the injection port from the coating surface is required. Since such fine adjustment is difficult to automate, it is determined by the operator's vision and the operator needs to operate the spray gun.

  On the contrary, in the case of manual work, the density of the adhesive can be eliminated, but it has been difficult to make the applied amount (particularly the total amount) of the adhesive uniform. The reason is that, if the spraying time by the spray gun is different, the application amount of the adhesive is similarly different. Therefore, in the case of manual application, in order to make the total amount of adhesive to be applied uniform, a sensation presentation device that can be noticed by an operator is installed in the application area.

  In other words, manual application involves dividing the coating surface of the substrate into several locations suitable for manual application, and then applying to each division according to a predetermined order, but knowing the time to apply for each division. It will be possible. Then, application for a predetermined time is performed for each section, and the application time for all sections is within an allowable range, whereby the amount of the solvent-type adhesive to be applied to the application surface of the base material is within the predetermined range. It is.

  Specifically, as shown in FIG. 2, the knowledge presentation device includes a controller 1, a detection means 2 that detects the state of the spray gun, and a knowledge presentation means 3. The detection means is provided with an output unit 22 in the spray gun installation unit 21, detects that the spray gun is installed, and that the spray gun has been taken out, and outputs it to the controller 1. The controller 1 includes a processing device 11 and a storage means (memory) 12. When the controller 11 detects the state of the spray gun, the processing device 11 reads the knowledge information stored in the memory 12 and sends it to the knowledge presentation means 3. An operation signal is output. Moreover, the input part 13 is connected to the processing apparatus 11, and it can input when setting the spraying process and spraying time of a spray gun. The input setting information is stored in the memory 12 and is read by the processing device during operation.

  The sense presentation unit 3 further includes an electronic sound generation circuit control unit 31, an electronic sound generation circuit 32, and an electronic sound generation unit 33, and generates an electronic sound based on an operation signal from the controller 1. is there. The electronic sound to be generated is classified into several types, indicating the pre-irradiation sound indicating the preparation of the spray gun, the start sound indicating the start of spraying by the spray gun, the conversion time sound indicating when the moving direction of the spray gun is changed, and the injection end There may be an end sound. When the processing device 11 detects the removal of the spray gun, data for determining a predetermined sound type, its order, and sound length is read from the memory 12, and the control for the electronic sound generating circuit control unit 31 is controlled according to this data. Output a signal. Since the electronic sound generator 33 emits an electronic sound in response to the control signal, a predetermined amount of solvent-type adhesive can be applied to the application surface by operating the spray gun according to the electronic sound.

  As an example of the generation of the electronic sound controlled by the electronic sound generation circuit control device 31, it is assumed that the continuous sound is generated when the spray gun is not sprayed and the sound is silenced during the spraying. When changing the direction of movement of the spray gun during spraying, use short sounds. When moving the spray gun to a predetermined position on the base material for applying solvent-type adhesive, it is in preparation time not to spray, so a predetermined continuous sound is generated and the time when the continuous sound ends is sprayed It can be a start signal. Thereafter, there is no sound during the first ejection time, and an electronic sound is generated at the end. The electronic sound at this time is a short time, the moving direction of the spray gun is changed, and the second ejection is performed while continuing the ejection. It is silent during the second ejection time. This is repeated, and when the final ejection time ends, an electronic sound is continuously generated. If there is a place to move the spray gun in the middle of the spraying time, it is possible to generate a continuous sound and make it aware that the spray gun should be moved while spraying with the spray gun is interrupted It is.

  Here, a specific example of the generation of an electronic sound will be described by taking a base material as shown in FIG. 3 as an example. FIG. 3A is a front view of the substrate, and FIG. 3B is a bottom view. As shown in this figure, the base material 100 to which the adhesive is to be applied is not a smooth plate shape, but is curved in a mountain shape at the central portion 111, and a flat surface is formed on both sides thereof. Each edge portion is formed with rounded surfaces 112 and 113, and an adhesive must be applied to these rounded surfaces. The curved ridge-side surface 110 is a coating surface, and the valley-side surface 120 is a back surface.

  When applying a solvent-type adhesive to the application surface 110 of the substrate 100 having such a shape, it is common to apply a flat portion after applying to the edge of the entire circumference. Therefore, the coating is applied counterclockwise along an edge from an arbitrary point on the entire circumference. In the figure, it moves from the starting point A to the adjacent point B, and is further applied to the entire periphery in the order of C, D, E, F, A. Thereafter, the coating is applied from the vicinity of the edge EF to the opposite edge CD while changing the direction in the vertical direction from the vicinity of the edge EF.

  The electronic sound (knowledge presentation) in the case of applying in this order generates a preparation sound before the start of injection. Although the preparation sound is a continuous sound, it is about several seconds (3 to 5 seconds). Subsequently, the continuous sound is stopped, or a short sound having a different tone is generated, thereby giving a notice of the start of injection. Silence during the injection time. The spraying time is set as 0.5 seconds with respect to the moving distance of the spray gun of 10 cm. This time can be appropriately changed. The first injection time is a time for applying to the edge AB. Since the length of the edge AB is 30 cm, the first injection time (silent time) is set to 1.5 seconds. Therefore, an electronic sound (short sound) for notifying the direction change is emitted 1.5 seconds after the start of injection. Subsequently, there is no sound during the second injection time for applying the edge BC. Since the length of the edge BC is 20 cm, the coating time is 1 second. Therefore, an electronic sound (short sound) that makes the user aware of the direction change is emitted after another second.

  Thus, when the third injection time (edge CD), the fourth injection time (edge DE), the fifth injection time (edge EF), and the sixth injection time (edge FA) are finished, Transition to application. In order to start the application of the plane portion from the position closest to the vertex A, it moves from the vicinity of the edge EF to the opposite edge CD. The spray gun moves from the vertex A to the vicinity of the vertex F. When this period is set as the movement period, a continuous sound for notifying that the fuel is not ejected is generated. In addition, when not making this period into a movement period, it can be made to be silent after a short sound, and to change to the injection of a plane part, spraying from a spray gun.

  As for the injection time in the plane portion, silence and short sound are repeated from the seventh injection time (in the vicinity of the edge EF) to the fourteenth injection time (in the vicinity of the edge CD). The time to do is appropriately different depending on the distance. And since the moving distance of the whole process performed by the above injection procedures is 400 cm, the total time from the 1st injection time to the 14th injection time becomes 200 seconds (3 minutes 20 seconds). In this case, a predetermined amount of the solvent-type adhesive can be applied to the substrate 100 by spraying the solvent-type adhesive from the spray gun during the total injection time (200 seconds).

That is, for example, when 5.9 g (± 0.05 g) of adhesive is applied to the coated surface of the substrate, 8.85 g of a solvent-type adhesive with a volatile content of 50% (before the solvent is volatilized) must be applied. I must. Therefore, when the spray amount per second by the spray gun is 44.25 mm ³ and the density (g / cm ³ ) of the solvent-type adhesive to be applied is 1.0, 200 seconds from the spray gun. By spraying, the total capacity of the coating amount can be 8.85 cm ³ . In this way, the spraying time by the spray gun is calculated according to the weight of the adhesive to be applied (adhesive after solvent volatilization) and the type of solvent-type adhesive, and this is divided by the total distance traveled by the spray gun. By doing so, it is possible to set the generation timing of the audible sound (electronic sound).

  As described above, a predetermined amount of adhesive is applied by spraying the solvent-type adhesive from the spray gun for a certain period of time, but when the operator manually operates the spray gun, There is a case where the jet is not ejected in the same way as the notifying method presented by the notifying presenting means. However, since it is guided timely by the awareness means, there is no significant difference, and the total amount to be applied as a whole can be injected. Furthermore, since the spray gun can be operated while checking the density of the application state according to the operator's sense, it is possible for the operator to eliminate the occurrence of overall unevenness.

  Note that the above-described sensation presenting means is not limited to electronic sounds. It is only necessary for the worker to be aware of it periodically. Therefore, for example, a part of the illumination for irradiating the coated surface of the base material may be turned on / off in accordance with the time. This is because the lightness and darkness of the coated surface become clear, and the worker can be made aware. In the case of lighting by the lighting device, the lighting state of the lighting should be continued during the time to be sprayed by the spray gun. Therefore, at the end of each spraying time, the user is made aware by turning off the light for a moment. It is also possible to distinguish from the state to be sprayed by blinking during the movement time of the spray gun.

  Next, an apparatus for inspecting whether or not the state of the applied adhesive conforms to a required adhesive amount condition (hereinafter referred to as application condition) will be described.

  FIG. 4 is a diagram showing an outline of the coating amount inspection apparatus. As shown in this figure, weighing means 4 and 5 are provided before and after the adhesive application step. There are two types: a pre-weighing unit 4 that measures the weight before application of solvent adhesive (hereinafter referred to as pre-weight) and a post-weighing unit 5 that measures the weight after solvent volatilization (hereinafter referred to as post-weight). is there. The pre-weighing unit 4 functions as a pre-weighing unit and is provided with a detection unit for detecting the start and end of weighing, and outputs a signal from the detection unit when the base material is taken out from the pre-weighing unit 4 Then, the management of the base material is started. That is, at the time when the base material is taken out from the pre-weighing unit 4, the detection unit functions as a pre-weighing detection unit, and the processing device 61 of the controller 6 has finished weighing and the measurement result (pre-weight value). Is output. When these pieces of information are input to the processing device 61, the processing device functions as a first assigning unit, assigns the order of the base materials (integer values), and sends the measurement results together with the integer values to the prior information storage unit. Is stored in the memory 62 functioning as:

  Here, the integer value (the order of the base materials) to be assigned is assigned the minimum integer value “1” for the measurement result of the first base material, and “1” is sequentially added for the measurement results of the subsequent base materials. Added and given. Therefore, this integer value matches the order in which the movement in the adhesive application process is started. Note that, as described above, in the adhesive application step, the solvent-type adhesive application step and the solvent volatilization step are sequentially performed, so the order given to the measurement results measured in the pre-measurement unit 4 (integer value) ) Also coincides with the order of the base materials after completing each step.

  Then, the posterior weight of the base material taken out from the solvent volatilization unit is measured by the posterior weighing unit 5. The post-measurement unit 5 functions as a post-measurement unit that measures the post-weight of the base material. When the posterior weight measurement is completed, the measurement result is output to the processing device 61, the processing device functions as a second assigning unit, and an order (integer value) is assigned to the measurement result. The processing device 61 functions as a weight determination unit, and simultaneously with the provision of the above order (integer value), the pre-weight (measurement result in the pre-weighing unit) in the same order (integer value) is read, and the adhesive weight calculating unit Thus, the substantial weight of the adhesive is calculated from the difference from the posterior weight. Further, in the processing device 6, the substantial adhesive weight and the required adhesive weight (acceptable weight range) are compared, and if the weight is within the acceptable weight range, it is determined as acceptable, and the acceptable weight. If it is out of the range, it will be rejected and the notification means will operate. As the notification means, the alarm sound generating unit 63 is operated by the alarm control unit of the processing device, and the operator is notified by the generation of the alarm sound.

  A processing method in the processing device for the determination will be described. 5 and 6 are flowcharts showing the processing method. FIG. 5 shows a processing method during measurement in the pre-weighing unit, and FIG. 6 shows a processing method during measurement in the post-measurement unit. As shown in FIG. 5, when it is detected that the base material is placed on the pre-measurement unit (S1), measurement in the pre-measurement unit is started (S2). Then, by detecting that the base material has been removed from the pre-weighing unit after the measurement result is detected, it is considered that the measurement has ended (S3). When the measurement end detection data at this time is input to the processing device, the measurement data input is allowed, and the processing device receives the measurement result (measurement value data) (S4). Furthermore, an integer value (order) is given to the input measurement value data, and the measurement value data and the integer value are stored in the memory. As described above, the pre-weighing process for one base material is finished, and when the next base material is placed, the same process is repeated. However, the given integer value is an integer value obtained by adding “1” to the immediately preceding integer value (next order). And these processes are repeated while the mounting of the base material continues.

  Next, as shown in FIG. 6, when the base material is placed on the post-weighing unit, measurement is started in the same manner as the pre-weighing unit (S11, S12). When the base material is placed on the post-weighing unit, the order (integer value) of the base material is determined, and the integer value and the measured value data are input to the processing device (S13). By inputting the integer value, the measurement data (preliminary data) in the preliminary weighing unit having the same integer value is read from the memory (S14). Further, the weight difference is obtained from both measurement data, and the adhesive weight is calculated (S15). Then, the weight condition data stored in the memory in advance is read, and the calculation result is compared with the weight condition data (S16). The weight condition data defines a range of weights to be matched, and it is determined whether or not the adhesive weight is within this range. When the adhesive weight deviates from the range of the weight condition data, an alarm activation signal is output and the alarm is activated (S17).

  In addition, since the subsequent base material is sequentially placed on the post-measurement unit, the order (integer value) is determined each time placement of the base material is detected. As in the case of the pre-weighing unit, the integer value at this time is assigned the smallest integer value (that is, “1”) at the first measurement after the start of processing, and “1” is added every time continuous measurement is performed. It is what you want to do.

  By the processing method as described above, it is possible to sequentially measure the weight of the adhesive and determine whether it is acceptable or not by sequentially performing pre-measurement and post-measurement on the substrate that is continuously conveyed. The above processing is an example in the case where the base material moves in a row (continuously) from the pre-weighing unit to the post-weighing unit. In particular, it is assumed that the solvent volatilization part is provided with a moving means and the volatilization of the solvent is completed after the movement by moving in the solvent volatilization part during a predetermined time.

  On the other hand, when using a solvent volatilization unit that does not include a moving means, that is, when using an apparatus that includes a plurality of installation units and passes a predetermined time at a certain location, the order of movement of the base material Need to manage. Therefore, in order to clarify the order of the base materials, the order of the base materials supplied to the solvent volatilization unit and the order of the taken out base materials may be managed in addition to the above apparatus.

  FIG. 7 is a diagram illustrating a management device in the solvent volatilization unit. As shown in this figure, the solvent volatilization section 7 is provided with a plurality of installation sections 71, 72,..., 78, and each of the installation sections 71 is individually provided with a substrate coated with a solvent-type adhesive. It can be installed (injected) in any one of -78. The base material is left for a predetermined time in a state of being installed in each of the installation parts 71 to 78, and the solvent is volatilized as time passes. The solvent volatilization unit 7 is also called a dryer, and is temperature-controlled so as to be maintained at a predetermined temperature.

  Therefore, each of the installation parts 71 to 78 of the solvent volatilization part 7 is provided with detection parts 81, 82,. Since this detection part 81-88 detects presence of a base material, when a base material is thrown in, when the base material is thrown in, it detects the insertion (functions as a supply detection means), and when a base material is taken out, The removal can be detected (functions as a discharge detection means). Specifically, these detectors 81 to 88 determine the presence or absence of a base material by an infrared sensor.

  When the detection units 81 to 88 detect the loading / unloading of the base material, the information is output to the processing device 91 of the controller 9. The detectors 81 to 88 are in a one-to-one relationship such that “detector 1” 81 detects “installer 1” 71 and “detector 2” 82 detects “installer 2” 72. Furthermore, each detection part 81-88 is recognized by the processing apparatus so that identification is possible. Therefore, in the processing device 91, it is possible to determine which of the installation units 71 to 78 is data based on the detection data. Therefore, when data is received from any of the detection units 81 to 88, the data is input as data of the installation units 71 to 78. At this time, it can memorize | store in the memory (memory | storage part information storage means) 92 with the detection time grasped | ascertained by the timer in a processing apparatus. And when the data which detected the taking-out of the base material from the detection parts 81-88 are input, while the processing apparatus 91 functions as a prior | preceding judgment means, it is judged whether the taking-out order is appropriate, and it is illegal taking-out. In this case, an alarm device (notification means) 93 is activated.

  Here, a processing method by the processing apparatus will be described. FIG. 8 is a flowchart of the processing method. As shown in this figure, when the base material is input to the solvent volatilization unit and the input of the base material is detected, location data (installation unit data) of the input installation unit is received together with the input detection data. (S31), information obtained by adding the input time data to this is stored in the memory (S32). When the subsequent base material is thrown into another installation part, the detection data, the installation part data different from the above and the input time are stored in the memory, and a plurality of base parts are appropriately installed in a plurality of installation parts Is stored in the memory. Next, when the base material is taken out from the installation part, the removal of the base material is detected, and the installation part data is received together with the detection data. At this time, all information stored in the memory is read and the times of the same installation section data are compared. That is, it is determined whether or not the time required from the time when it is introduced into the installation section to the time when it is taken out exceeds a predetermined time (a time during which the solvent is sufficiently volatilized). The predetermined time is stored in the memory in advance, and as a result of comparison with the time, if the predetermined time or more has not elapsed, an alarm activation signal is output as inappropriate and the alarm device is activated (S36). At the same time, it is determined whether or not the loading time of the pulled-out base material is the earliest than the other loading time by comparing with other installation part data stored in the memory (S37). In the case where a material later than the loading time of the base material put into another installation unit is taken out first, the order of movement is regarded as inappropriate, and also in this case, an alarm activation signal is output (S36). . Although not shown, the alarm activation signal is interrupted by returning the base material back into the installation section, and the re-input time is stored. When the recharging time is recorded, it is determined whether or not the leaving time in the solvent volatilization unit is appropriate based on the total time of two charging / unloading.

  When the above processing is properly performed, the installation part data is erased, and when the next base material is input to the same installation part, input detection data and installation part data are input as input of a new base material, It will be stored in memory. Therefore, the installation part data stored in the memory is information on only the base material put in the solvent volatilization part.

  In addition, the said processing apparatus can also use the processing apparatus in the above-mentioned coating amount inspection apparatus. In this case, when input detection data when the base material is input is input, an integer value can be given in addition to the input time. Then, as the integer value at this time, after the processing apparatus starts to operate, the first input is given the smallest integer value “1”, and thereafter, the integer value obtained by sequentially adding “1” is given. You may process as follows. According to such a processing method, the integer value given in the coating amount detection device matches the integer value of the management device in the solvent volatilization unit, and both indicate the order of the base materials, and unified management is performed. It is possible.

  Further, the notification means may be configured to also serve as the notification means used in the above-described coating amount inspection apparatus. However, in order to clearly distinguish whether the weight is unacceptable or the movement order is poor, it is preferable to provide the notification means individually.

  The embodiments of the present invention are as described above, but the present invention is not limited to the above-described embodiments, and various forms can be made without departing from the spirit of the invention.

  For example, depending on the type of substrate to which the adhesive is to be applied, the solvent-type adhesive may be applied simultaneously to a plurality of substrates. This is the case where the inner panel of the vehicle door is processed simultaneously on the left and right. In such a case, if the direction in which the base material moves from the coating process toward the solvent volatilization process is the right direction, the right door inner panel is the previous order, and if the direction is to the left, the left door The movement order can be clarified by giving the inner panel to the previous order at the time of each detection.
