It is mounted on a mounting base 150 extending in the transport direction via legs (not shown) provided at a predetermined interval in 112.

  The pachinko machine P is placed on the rollers 114 of the roller conveyor 110 in a substantially vertical standing posture in the horizontal direction with the front surface and the rear surface facing in the width direction intersecting the transport direction. All the rollers 114 are rotated in the same direction by driving means (not shown), and are configured to convey a pachinko machine P in a standing posture placed on the rollers 114 group to the downstream side. Each roller 114 is pivotally supported between the pair of conveyor frames 112 and 112.

The pair of guide members 116, 116 are separated from the roller 114 in the axial direction of the roller 114 by substantially the same length as the thickness dimension (front-rear direction dimension) of the pachinko machine P, and between the guide members 116, 116. It is configured so that the lower part of the pachinko machine P faces. It is recommended that the roller 114 and the guide member 116 are made of synthetic resin and preferably coated on the surface thereof with fluororesin or the like to reduce friction so that the pachinko machine P is hardly damaged.

  The conveyance stop mechanism 120 is a conveyance stop device for a roller conveyor, and is turned on when the stopper 121, the elevator 122 that raises and lowers the stopper 121, and the pachinko machine P is stopped at the certificate paper inspection position T. And a detection switch 123. 8A is a side view of the conveyance stop mechanism 120 showing the state where the stopper 121 is in the lowered position, and FIG. 8B is the state where the stopper 121 is in the raised position. FIG. 9 is a side view of the transport stop mechanism 120 showing a state in which the stopper 121 is at the raised position and the pachinko machine P is stopped at the certificate inspection position T. Further, the detection switch 123 constitutes the conveyance detection means of the present invention.

  The stopper 121 is an L-shaped member 121a having a substantially L-shape in side view, and is pivotally supported around the shaft 121b parallel to the axial direction of the roller 114 on the L-shaped member 121a. And a pachinko machine P).

  The elevator 122 is disposed below the roller conveyor 110, is fixed to the cylinder 122a, the piston rod 122b that moves up and down relative to the cylinder 122a, and the upper end of the piston rod 122b, and moves up and down as the piston rod 122b moves up and down. It has a fixing member 122c to be configured. The above-mentioned L-shaped member 121a is connected and fixed to the fixing member 122c via a shaft 121d provided at the lower front end, and the L-shaped member 121a rotates about a predetermined angle along the transport direction about the shaft 121d. It is provided as possible. Further, a spring 122d is provided between the upper surface of the fixing member 122c and the lower surface of the L-shaped member 121a, and the L-shaped member 121a is always inclined at a predetermined angle about the shaft 121d toward the rear side in the conveying direction (left side in FIG. 8). It is energized to be in a state.

  A detection switch 123 is provided on the upper surface in the vicinity of the front end (right side in FIG. 8) of the fixing member 122c in the conveyance direction so as to be able to appear and retract. Therefore, the end of the L-shaped member 121a opposite to the shaft 121d is always lifted by the urging force of the spring 122d and a gap is formed between the upper surface of the fixed member 122c. The member 122c is in an off state protruding from the upper surface.

  On the other hand, as shown in FIG. 9, in the state where the stopper 121 is in the raised position and the pachinko machine P is stopped at the certificate inspection position T, the contact roller 121c comes into contact with the outer frame 10 of the pachinko machine P, and the L-shaped The member 121a is rotated to the right against the biasing force of the spring 122d, and the detection switch 123 is pressed by the lower surface of the L-shaped member 121a. Accordingly, the detection switch 123 is turned on, and an on signal as a conveyance detection signal is sent to the control device 140. Further, the impact when the pachinko machine P comes into contact with the contact roller 121c and the conveyance is stopped is absorbed to some extent by the spring 122d contracting. The elevator 122 may be of any type as long as it fulfills such a function, and an air operated type or a hydraulic type can be used.

  As shown in FIGS. 9 to 11, the certificate detection device 130 includes two color discrimination sensors 131 and 131 and a stand 139 to which the color discrimination sensors 131 and 131 are attached by combining a plurality of round bar members. The stand 139 is fixed on the mounting table 150 along the roller conveyor 110. 10 is a schematic diagram of the color discrimination sensor 131, and FIG. 11 is a block diagram showing the internal configuration of the color discrimination sensor 131. As shown in FIG.

  The color discrimination sensor 131 is a device that detects an object based on the color component of the reflected light of the projected light, and includes a sensor head portion 132, an electric cable 133, a main body portion 134, and an output cable 135. . A plurality of electric wires are provided inside the electric cable 133.

  As shown in FIG. 10, the electric cable 133 extending from the sensor head portion 132 is connected to the main body portion 134. An output cable 135 extending from the main body 134 is connected to the control device 140.

  The sensor head portion 132 is provided with a light projecting optical system 132a and a light receiving optical system 132b. The light L emitted from the light projecting optical system 132a is reflected by the object W and enters the light receiving optical system 132b. In the state where the pachinko machine P is located at the certificate inspection position T, as shown in FIG. 6, the sensor head 132 of the two color discrimination sensors 131 has one sensor head 132 attached to the certificate stamp. The stand 139 is mounted at a predetermined height and a horizontal position so as to be substantially opposed to the position A1 with a predetermined distance and the other sensor head part 132 to be substantially opposed to the certificate sticking position A2 with a predetermined distance. It has been. The distance between the sensor head portion 132 and the stamp sticking position A1 or A2 is not an obstacle to the transport of the pachinko machine P, and the irradiation of the blue spot light from the light projecting optical system 132a and the reflected light from the light receiving optical system 132b. The length is set so that light can be normally received.

  The main body 134 includes an output indicator lamp 134a, an LCD display monitor 134b, a mode key 134d, a setting key 134e, an upper key 134f, and a lower key 134g. As shown in FIG. 6, each of the main body parts 134 of the two color discrimination sensors 131 includes a stand 139 base portion below one sensor head portion 132 and a stand 139 base portion below the other sensor head portion 132. And attached to each. The output indicator lamp 134a displays the detection state (detection and non-detection) of the object W by lighting and non-lighting. The LCD display monitor 134b displays, for example, the current amount of received light or the current degree of coincidence almost in real time. Here, the current amount of received light is the amount of reflected light received based on the current emission of one color. The mode key 134d is used by the user to change the operation mode. The setting key 134e, the upper key 134f, and the lower key 134g are used when setting a reference color.

  The reference color setting process is as follows. That is, when the setting key 134e is pressed in a state where the spotlight C1 is irradiated with the blue spot light from the light projecting element 132d through the light projecting optical system 132a, the reflected light from the certificate paper C1 enters the light receiving optical system 132b, and the light receiving element 132f. The color component of the reflected light received by the light receiving circuit 132g is stored in the storage unit 134m as a reference color.

  Next, the internal configuration of the color discrimination sensor 131 will be described with reference to the block diagram of FIG. The sensor head 132 of the color discrimination sensor 131 includes a light projecting optical system 132a, a plurality of light projecting elements 132c, 132d, 132e, a light receiving optical system 132b, a light receiving element 132f, and a light receiving circuit 132g. The main body part 134 of the color discrimination sensor 131 includes a light projection control part 134h, a signal processing control part 134i, an output circuit 134j, a setting input part 134k, a main body side display part 134l, and a storage part 134m. The light projecting optical system 132a and the light projecting elements 132c, 132d and 132e are the light projecting means of the present invention, the light receiving optical system 132b, the light receiving element 132f and the light receiving circuit 132g are the light receiving means, and the signal processing control unit 134i is the determining means. The storage unit 134m constitutes a storage unit.

  The light projection control unit 134h controls the light emission operation of the plurality of light projecting elements 132c to 132e of the sensor head unit 132. Specifically, a light projection timing signal indicating the light emission timing of each of the plurality of light projecting elements 132c to 132e is output to the plurality of light projecting elements 132c to 132e and the signal processing control unit 134i through the electric wire cable 133.

  The plurality of light projecting elements 132c to 132e are, for example, LEDs (light emitting diodes). The light emission colors of the light projecting elements 132c to 132e are different. In the present embodiment, the light projecting element 132c emits green light, the light projecting element 132d emits blue light, and the light projecting element 132e emits red light.

  The light projecting optical system 132a and the light receiving optical system 132b are configured by lenses or the like, for example. The light L generated by the plurality of light projecting elements 132c to 132e is emitted to the outside through the light projecting optical system 132a. In the light receiving optical system 132b, the light L reflected by the object W among the light L emitted to the outside by the light projecting optical system 132a is incident.

  The light L incident on the light receiving optical system 132b is guided to the light receiving element 132f. The light receiving element 132f generates a light receiving signal corresponding to the amount of received light. The light receiving circuit 132g amplifies the light reception signal generated by the light receiving element 132f and transmits the amplified light reception signal to the signal processing control unit 134i of the main body 134 through the electric wire cable 133.

  The signal processing control unit 134i performs predetermined signal processing on the received light signal, and outputs a detection signal indicating detection and non-detection of the object W to the outside via the output circuit 134j. The signal processing control unit 134i performs reference color setting processing and output determination processing as the predetermined signal processing. Further, the signal processing control unit 134i causes the main body side display unit 134l to display predetermined information based on the received light reception signal and the operation of the setting input unit 134k by the user. As described above, the storage unit 134m stores the color components of the reference color set by the reference color setting process.

  Next, the flow of the certificate inspection process in the certificate inspection apparatus 101 will be described with reference to the flowchart of FIG.

  When the operation start is instructed from the control device 140, the driving of the roller conveyor 110 is started, and the light projecting elements 132d and 132da of the color discrimination sensors 131 and 131 are turned on to start the blue light (S101). ). When the pachinko machine P transferred from the certificate sticking step S25 is transported on the rollers 114 of the roller conveyor 110, the piston rod 122b and the fixing member 122c of the elevator 122 are operated to the raised position. The stopper 121 is also raised and the contact roller 121c protrudes upward from between the rollers 114 (S102).

  When the pachinko machine P is conveyed as it is, the outer frame 10 comes into contact with the contact roller 121c of the stopper 121 and the conveyance of the pachinko machine P is stopped (S103). The stop position of the pachinko machine P is the certificate inspection position T. Further, when the transport of the pachinko machine P is stopped, the L-shaped member 121a rotates slightly clockwise about the shaft 121d, and the detection switch 123 is pressed to reach the certificate inspection position T of the pachinko machine P. (Inspection position arrival signal) indicating is sent to the control device 140 (S104). Further, when the L-shaped member 121a rotates and the spring 122d contracts, the kinetic energy of the pachinko machine P, which is a conveyed product, is absorbed, and the impact associated with the stop of the pachinko machine P is reduced.

  When the control device 140 receives the inspection position arrival signal from the conveyance stopping device 120, the control device 140 starts counting time by a built-in timer (S105). When a predetermined waiting time (1.5 seconds in the present embodiment) has elapsed (S105: Yes), the color discrimination sensors 131 and 131 execute certificate stamp detection processing (S106). That is, the presence / absence of the stamp C1 at the stamp pasting position A1 and the presence / absence of the stamp C2 at the stamp pasting position A2 are detected by the color discrimination sensors 131 and 131, respectively (S106). The reason for waiting for a predetermined time after receiving the inspection position arrival signal from the conveyance stop mechanism 120 is that the vibration associated with the conveyance stop of the pachinko machine P is sufficiently attenuated to detect the presence or absence of the stamp. It is for preventing.

  Here, the flow of the certificate detection process in the color discrimination sensor 131 will be described with reference to the flowchart of FIG. Note that the storage 134m (nonvolatile memory) of the color discrimination sensor 131 stores in advance the color components of the reflected light when the blue spot light output from the light projecting optical system 132a is projected onto the white certificate papers C1 and C2. It is stored as a reference color.

  First, the signal processing control unit 134i of the color discrimination sensor 131 reads the received light information of the reflected light that is incident from the light receiving optical system 132b and received by the light receiving element 132f (S201). Next, it is determined whether the amount of reflected light received is within the normal range (S202). That is, when the received reflected light is insufficient or excessive, the color cannot be determined correctly. When the amount of reflected light is within the normal range (S202: Yes), it is determined whether or not the degree of coincidence between the color component of the received reflected light and the color component of the reference color stored in the storage unit 134m is equal to or greater than a threshold value. (S203). If the matching degree of the color components is equal to or greater than the threshold (S203: Yes), an output signal indicating “certificate detection” is output from the output circuit 134j (S204), and this routine ends. When the amount of reflected light is not within the normal range (S202: No), or when the color component coincidence is less than the threshold (S203: No), the output circuit 134j outputs an OFF signal indicating “certificate non-detection”. (S205), this routine is terminated.

  When both the output signals from the color discrimination sensors 131 and 131 are ON, that is, when both the certificate paper C1 and the certificate paper C2 are detected (S107: Yes), the control device 140 determines the piston rod 122b of the elevator 122. Is lowered (S108). Along with this, the stopper 121 is also submerged below the roller conveyor 110, and the pachinko machine P moves again on the roller conveyor 110 to the downstream side and is used for the next packaging step. When the next pachinko machine P approaches, the piston rod 122b of the elevator 122 is raised again and the above operation is repeated (S102 to S108).

  On the other hand, when one or both of the outputs of the color discrimination sensors 131 and 131 are off, that is, when one or both of the certificate sheets C1 and C2 are not detected (S107: No), the red lamp 141 is turned on and the buzzer is turned on. A certificate absence notification operation including the ringing of 142 is executed (S109), and the operator is notified that the certificate absence is detected. At this time, since the transport of the pachinko machine P is stopped, the operator visually confirms that the stamp C1 etc. are not stuck at the stamp sticking position A1, etc., and performs the task of correctly sticking the stamp C1 etc. be able to. When the certificate sticking operation is finished and the restart switch 143 is operated (S110: Yes), the notification operation is canceled (S111), and the steps after S102 are executed again.

  As is clear from the above detailed description, according to the certificate inspecting apparatus 101 of the present embodiment, the certificate detecting device 130 is in the stamp application positions A1, A2 with the pachinko machine P placed at the certificate inspection position T. Since the presence or absence of the stamps C1 and C2 is detected, whether or not the stamps C1 and C2 are correctly applied to the certificate sticking positions A1 and A2 of the pachinko machine P can be reliably inspected.

  Further, when the roller conveyor 110 conveys the pachinko machine P in an upright state in which the front surface and the rear surface are directed in a direction crossing the conveyance direction, and the detection switch 123 detects that the pachinko machine P has been conveyed to the certificate sheet inspection position T. The stamp detecting device 130 disposed on the side of the transport path of the roller conveyor 110 detects the presence or absence of the stamps C1 and C2 at the stamp pasting positions A1 and A2, so that the stamp inspection is performed while the pachinko machine P is transported to the next process. Can be done automatically.

  In addition, the transport stop mechanism 120 stops the pachinko machine P transported by the roller conveyor 110 at the certificate inspection position T, and the certificate detector 130 is in the state where the certificate printing position is stopped while the pachinko machine P is stopped at the certificate inspection position T. Since the presence or absence of the stamps C1 and C2 in A1 and A2 is detected, it is possible to accurately inspect the stamp sticking. In particular, since the presence or absence of the stamp is detected while the pachinko machine P stops at the stamp inspection position T and waits for a predetermined time and the vibration accompanying the conveyance of the pachinko machine P is almost converged, erroneous detection of the presence or absence of the stamp is prevented. be able to.

  When the certificate detecting device 130 detects that “certificate is present”, the conveyance stop mechanism 120 releases the pachinko machine P from the conveyance stop state and the conveyance is resumed. The machine P is reliably conveyed to the packaging process S26 which is the next process. On the other hand, when “no certificate” is detected by the certificate detection device 130, the conveyance stop state of the pachinko machine P by the conveyance stop mechanism 120 is continued, so that the certificate paper P1 and / or C2 is not properly attached. Can be prevented from being transferred to the packaging step S26, which is the next step.

  Further, the color discrimination sensors 131 and 131 of the certificate paper detection device 130 have light projection elements 132d having a predetermined wavelength (blue spot light) with respect to the certificate paper sticking positions A1 and A2 of the pachinko machine P through the light projection optical system 132a. And the light receiving element 132f receives the reflected light from the stamp sticking positions A1 and A2 via the light receiving optical system 132b, based on the light receiving information (color component) obtained from the light receiving element 132f by the signal processing control unit 134i. The presence or absence of the stamps C1 and C2 is determined. Therefore, since each light projecting optical system 132a of the color discrimination sensors 131 and 131 projects light of a predetermined wavelength to the certificate paper pasting positions A1 and A2, without being affected by disturbance light such as lighting in the factory, Each of the light receiving optical systems 132b can stably receive the reflected light, and with a simple configuration, the presence or absence of the sticker can be accurately inspected without contact.

  Further, the color discrimination sensors 131 and 131 store the color component of the reflected light in the case where light of a predetermined wavelength (blue spot light) is projected onto the certificate papers C1 and C2 as a reference color in the storage unit 134m, and each light receiving optical system. Based on the degree of coincidence between the color component of the reflected light obtained from 132b and the reference color, it is possible to determine the presence or absence of the certificate sheets C1 and C2. Here, FIG. 14 is a diagram showing a state in which the blue spot light is projected at the stamp sticking position A1 of the main body frame 20, and FIG. 14 (a) shows the case where the stamp paper C1 is stuck. (b) is a figure which respectively shows the case where the certificate paper C1 is not affixed. Moreover, in these figures, the resin part colored in the amber color etc. of the main body frame 20 is represented by shading. As shown in FIG. 14A, in the state where the stamp C1 is pasted at the stamp pasting position A1 set on the resin portion colored in a dark blue color or the like of the main body frame 20, the light projecting element 132d has the light projecting optical system 132a. Since the blue spot light is projected onto the certificate paper C1 through the light receiving element 132f and the light receiving element 132f receives the reflected light from the certificate paper C1 through the light receiving optical system 132b, the degree of coincidence between the color component of the reflected light obtained from the light receiving element 132f and the reference color Becomes bigger. On the other hand, as shown in FIG. 14B, in the state where the certificate paper C1 is not attached to the certificate paper attachment position A1, the light projecting element 132d projects blue spot light onto the resin surface of the main body frame 20 through the light projection optical system 132a. Since the light receiving element 132f receives the reflected light from the resin surface through the light receiving optical system 132b, the degree of coincidence between the color component of the reflected light obtained from the light receiving element 132f and the reference color becomes small. Therefore, it is possible to reliably determine whether or not the certificate C1 is present at the certificate affixing position A1 of the main body frame 20 based on the degree of coincidence between the color component of the reflected light obtained from the light receiving optical system 132b and the reference color. it can. Further, the determination of the presence or absence of the stamp C2 at the stamp pasting position A2 set on the transparent resin main board box 82 is also the same.

  Further, the light projecting optical system 132a and the light receiving optical system 132b of the color discrimination sensors 131 and 131 are disposed so as to substantially face the stamp attachment positions A1 and A2, respectively, when the pachinko machine P reaches the certificate inspection position T. Therefore, each of the light projecting optical systems 132a can reliably project light having a predetermined wavelength to the certificate paper pasting positions A1 and A2, and each of the light receiving optical systems 132b can provide the stamp paper pasting positions A1 and A2. The reflected light from A2 can be reliably received.

  Further, when the certificate detector 131 detects that there is no certificate, a notification operation is performed by turning on the red lamp or sounding the buzzer, so that the operator can place the certificate C1, C2 at the certificate application positions A1, A2 of the pachinko machine P. Can be surely recognized that the sticker is not correctly attached, and the sticker attaching operation of the pachinko machine P can be performed again.

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

  For example, in the embodiment, the pachinko machine P transported by the roller conveyor 110 is stopped by the transport stop mechanism 120 at the certificate inspection position T, and the certificate detector 130 is in a state where the pachinko machine P is stopped at the certificate inspection position T. The pachinko machine P is detected at the stamp pasting positions A1 and A2, and the pachinko machine P is attached to the pachinko machine P while the pachinko machine P is being moved by the roller conveyor 110 without stopping at the certificate paper inspection position T. A configuration may be used in which the presence or absence of the stamps C1 and C2 at the stamp pasting positions A1 and A2 is detected by the stamp detection device 130 fixed on the table 150. Since the color discrimination sensors 131 and 131 have a response speed of 1 ms, high-precision color discrimination is possible even for a moving workpiece (pachinko machine P). According to this modification, the stamp inspection process can be completed in a short time and the pachinko machine P can be transported to the next process. In this case, the conveyance stop mechanism 120 may stop the conveyance of the pachinko machine P when the certificate detection device 130 detects that there is no certificate. Thereby, it is possible to prevent the pachinko machine P to which the stamp C1 or the like is not properly attached from being conveyed to the next process.

  In the embodiment, the storage unit 134m of the color discrimination sensor 131 further stores the amount of reflected light when light of a predetermined wavelength is projected onto the certificate sheets C1 and C2 as a reference amount of light, and the light receiving optical system 132b and the light receiving optical system 132b. Based on the degree of coincidence between the color component of the reflected light obtained from the element 132f and the reference color and the ratio of the amount of reflected light to the reference light amount, the presence or absence of the certificate sheets C1 and C2 may be more accurately determined. That is, in the state where the stamp C1 is pasted at the stamp pasting position A1, etc., the light receiving element 132f receives the reflected light from the stamp C1 etc. through the light receiving optical system 132b, so that the color component of the reflected light obtained from the light receiving element 132f is received. The degree of coincidence between the reference color and the reference color increases, and the ratio of the amount of reflected light to the reference light amount is close to 1. On the other hand, in the state where the certificate C1 or the like is not attached at the certificate application position A1 or the like, the light receiving optical system 132b receives the reflected light from the surface of the main substrate box 82 or the resin surface of the main body frame 20, and thus is obtained from the light receiving element 132f. The degree of coincidence between the color component of the reflected light and the reference color is small, and the ratio of the light amount of the reflected light to the reference light amount is a value farther than 1. Therefore, it is possible to reliably determine whether or not the stamp C1 is present at the stamp pasting position A1 based on the degree of coincidence between the color component of the reflected light and the reference color and the ratio of the amount of reflected light to the reference light. Can do.

  In addition, when there is a large difference in the amount of reflected light between the stamp C1, C2 and the stamp pasting position (the surface of the main board box 82 or the resin surface of the main body frame 20), the reflected light is not used without using the color component of the reflected light. The presence or absence of the certificate sheets C1 and C2 may be determined based only on the amount of light.

  Moreover, in the said embodiment, although the blue spot light was projected with respect to certificate stamp application position A1, A2 in order to detect certificate stamp C1, C2, the other predetermined wavelength, such as green light and red light, was shown. You may make it project light. For example, the wavelength of the light to be projected may be changed according to the color of the certificate paper.

  In the above embodiment, the blue spot light is always projected from the light projecting element optical system 132a after the operation of the certificate inspecting apparatus 101 is started. However, the pachinko machine P is transported at the certificate inspection position T. The light projection may be started at the time when it is stopped and turned off when the certificate detection processing is completed.

  In the above embodiment, an example is shown in which two sheets of stamp attached to the back of the pachinko machine P are detected. However, the number of sheets can be changed according to the number of sheets attached. Alternatively, it may be configured to detect three or more certificate sheets.

  Moreover, in the said embodiment, although the example using the roller conveyor 110 was shown as a conveyance means for conveying the pachinko machine P, it is good also as a structure which uses a belt conveyor.

  In the embodiment, the color discrimination sensor 131 detects the presence or absence of the certificate, but the CCD image pickup device is used to take an image of the certificate sticking position of the pachinko machine P, and the certificate based on the photographed image.
