JP-A-2-21980

  In the conventional partition wall device with a cleaning function as described above, regardless of whether the blade is in use or not, it is always pressed against the surface of the translucent wall and transmits ultraviolet light emitted by a fluorescent lamp. It is in a state of being irradiated through the wall portion, deteriorates at an early stage, cracks are generated, and proper cleaning performance is not exhibited.

  In addition, when the granular material is like brown rice immediately after the rice bran, when the blade is reciprocated, the rice cake adheres to the front and rear surfaces of the blade. In the process of moving the surface, it is detached from the blade and remains on the surface already cleaned by the blade, and the proper cleaning performance is not exhibited.

  An object of the present invention is to provide a partition wall device with a cleaning function that solves these problems and enables high-quality imaging of a camera through a translucent wall.

  In order to achieve the above object, the present invention is as follows.

In Claim 1, the partition wall by which one part was used as the translucent wall part, the braid | blade which can be elastically deformed located in the one side of this translucent wall part, and this braid | blade on one side of the said translucent wall part When the partition wall is viewed from a direction perpendicular to the surface of the partition wall device with a cleaning function, the drive device includes a drive unit that reciprocates along a specific locus along the surface in a state of being pressed against the surface of the partition wall. And a blade drive guide means for moving the blade to a position outside the region of the through-hole wall portion and to a position separated from the through-hole wall portion and the partition wall by a specific distance. A scraper that scrapes off deposits adhering to the front and rear surfaces of the blade at a position outside the region of the through-hole wall is provided .

In Claim 2, The partition wall apparatus with a cleaning function of Claim 1 WHEREIN: While the said blade is reciprocated between the one end vicinity of the said translucent wall part and the other end vicinity, the said scraper is near the said one end. And installed near each of the other ends .

  According to the present invention described above, the imaging performance of the camera by passing through the transmission wall can be maintained well over a long period of time. When used in a color sorter such as the above, it becomes possible to accurately sort different color granular materials.

The effects of the invention described in each claim are as follows.
According to the first aspect of the present invention, a partition wall that is partially formed as a translucent wall, an elastically deformable blade that is positioned on one side of the translucent wall, and the blade that is the translucent wall In a partition wall device with a cleaning function, comprising a driving means for reciprocating along a specific locus along the surface in a state of being pressed against the surface on one side of the part, the partition wall from a direction orthogonal to the surface thereof A blade driving guide for moving the blade to a position outside the region of the through-hole wall portion when viewed, and to a position separated from the through-hole wall portion and the partition wall by a specific distance. In the direction perpendicular to the surface of the partition wall , the means is to scrape off the adhering material adhering to the front and rear surfaces of the blade at a position outside the region of the through-hole wall portion. When viewed from the outside of the area of the through-hole wall The blade in the stopped state prevents the light from traveling straight through the light-transmitting wall portion by moving the blade to a position at a specific distance from the through-hole wall portion and the partition wall portion. In addition, the blade is in a state where ultraviolet rays or the like that have passed through the translucent wall from the side where the blade does not exist on one side of the partition wall and reach the other side do not directly shine on the blade Deterioration of the blade is prevented, and the blade does not come into contact with the translucent wall or partition wall, so that internal stress is unlikely to occur in the blade material and mechanical wear of the blade is avoided, and the cleaning ability of the blade is unlikely to decrease. Thus, the translucent performance of the translucent wall can be maintained satisfactorily.

  Also, since the deposits on the front and rear surfaces of the blade are scraped off by the scraper, the front and rear surfaces of the blade are kept clean, and the blade is cleaning the deposits on the translucent wall. It is difficult for the attached matter of the blade to fall on the surface of the light-transmitting wall portion that has been cleaned, and the light-transmitting performance of the light-transmitting wall portion can be maintained well.

  In addition, since the scraper scrapes off the blade adhering material at a position outside the region of the through-hole wall portion, the adhering material separated from the blade by the scraper is difficult to adhere to the surface of the light-transmitting wall portion. Thus, the light transmission performance of the transmission wall portion is further ensured.

According to the second aspect of the present invention, the adhering matter adhering to the blade can be scraped off by the scraper at the initial stage of each reciprocating movement of the blade. This effect can be further promoted.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Sectional drawing which shows a part of apparatus, FIG. 4: is operation | movement explanatory drawing of the said partition wall apparatus with a cleaning function.

  As shown in FIG. 1, the granular material color sorter equipped with the partition wall device with a cleaning function according to the present invention is a pebbles, a metal piece, a glass piece or a defective quality mixed in a granular material w such as grain. It removes the different-colored granular material w1 such as a granular material, and forms a sorting unit 100 on the machine frame and is provided with a raw material tank 101, a non-defective product tank 102, and a defective product tank 103 at appropriate locations. In FIG. 1, the left side is the front and the right side is the rear.

  The sorting unit 100 includes a feeder 1 that quantitatively feeds the granular material w sent from the raw material tank 101 to the rear, a flowing-down rod 2 to which the granular material w is supplied from the feeder 1, and a granular material that has dropped from the flowing-down rod 2 An optical sorting unit 3 that sorts and removes the different color granular material w1 from the w group, and a separate collection unit 4 including a non-defective product containing unit 4a and a defective product containing unit 4b are provided.

  The feeder 1 is fixed to the machine frame and accommodates the granular material w from the raw material tank 101, the trough 6 disposed below this to support the granular material w on the upper surface, and the electromagnetic that vibrates the trough 6 In this case, the trough 6 changes the amplitude and period of the vibration applied from the electromagnetic driving means 7 to change the granular material w conveying force to be large or small. The flow rate control device 8 for controlling the supply capacity of the feeder 1 automatically controls the amplitude and period of vibration generated by the electromagnetic drive means 7 so that good sorting accuracy of the optical sorting unit 3 can be obtained. is there.

  The flow-down rod 2 is formed with a groove forming a straight flow-down guide surface 2a on the upper surface and is supported in an inclined manner by the body frame. The flow-down guide surface 2a receives the granular material w supplied to the guide start end thereof. The granular material w group is formed into a single layer during the guidance and is made to fly obliquely forward and downward.

  The optical sorting unit 3 includes a granular material processing chamber 9 in which the periphery of the normal flight trajectory a1 of the granular material w flying diagonally forward and downward from the lower end of the flow basket 2 is enclosed in a substantially hermetically sealed manner, and an upper portion of the granular material processing chamber 9 A pair of imaging chambers 10A and 10B disposed opposite to each other so as to sandwich the granular material processing chamber 9 in the front-rear direction at the close position and a function of cleaning the boundary between the granular material processing chamber 9 and each of the imaging chambers 10A and 10B The partition wall device 11 is divided into dust-tight shapes, and further, different color particle presence detecting means 12 and external force applying means 13 are formed, and ventilation means 14 for the granular material processing chamber 9 is provided.

  The granular material processing chamber 9 is surrounded by partitioning wall devices 11 and 11 with a cleaning function, an upper casing 15a, a lower casing 15b, and a separate collection unit 4, and each of the imaging chambers 10A and 10B has a partitioning wall device 11 with a cleaning function. Surrounded by a casing 16.

  As shown also in FIG.2 and FIG.3, each of the partition wall apparatuses 11 and 11 with a cleaning function corresponding to each imaging chamber 10A, 10B has the partition wall 17 by which one part was used as the translucent wall part 17a, And an elastically deformable blade 18 positioned on the particulate material processing chamber 9 side of the light transmitting wall portion 17a, and further presses the blade 18 against the surface of the light transmitting wall portion 17a on the particulate material processing chamber 9 side. In this state, the driving means 19 is provided for reciprocating along a specific locus in the left-right direction b along the surface.

  At this time, the translucent wall portion 17a is provided with a long square-shaped through hole c1 in the partition wall 17, and by fixing a transparent plate 20 such as a glass plate or a resin plate that covers the through hole c1 in a dense manner. Strictly speaking, the transparent plate 20 is formed at a portion overlapping the through hole c1. The blade 18 is formed of a long rectangular rubber plate, and the drive means 19 includes a rodless cylinder 21 fixed to the body frame in the left-right direction, and a first arm extended from an output member 21a of the cylinder 21. A member 22 and a connecting rod member 23 fixed to the tip of the first arm member 22, and a blade upper edge support piece 19 to which a blade 18 is fixed at each end of the connecting rod member 23 in the direction of the arrow. (Direction substantially orthogonal to the transparent plate 20) The plate spring members 24 and 24 are coupled to be elastically displaceable at d1. Accordingly, the blade 18 in each of the partition walls with cleaning function 11, 11 surrounding each of the imaging chambers 10 </ b> A, 10 </ b> B is driven by the common driving means 19.

  The rodless cylinder 21 has air inlets and outlets e1 and e2 at the left and right ends, and each of the air inlets and outlets e1 and e2 corresponds to one of the two air ports f1 and f2 of the electromagnetic direction switching valve 25. , 26b, and the air inlet f3 of the electromagnetic direction switching valve 25 is connected to the compressed air supply source 27 by an air supply line 28a. At this time, when the electromagnetic coil of the electromagnetic direction switching valve 25 is energized, the compressed air is supplied from the compressed air supply source 27 to the one side air pipe 26a and flows into the corresponding cylinder chamber, and the piston is Thus, the output member 21a is moved in the right direction b1, so that the air in the other cylinder chamber is pushed out by the piston and discharged from the air discharge port f4 of the electromagnetic direction switching valve 25 through the other air pipe 26b. Conversely, when the electromagnetic coil of the electromagnetic direction switching valve 25 is de-energized, compressed air is supplied from the compressed air supply source 27 to the air pipe 26b on the other side, and the cylinder chamber on the corresponding side is supplied. And the piston is pushed and moved in the opposite direction, and the output member 21a is moved in the left direction b2, so that the air in the cylinder chamber on one side is pushed out by the piston and It is discharged from the air outlet f4 electromagnetic directional control valve 25 through the side of the air tube 26a.

  A cleaning air injection nozzle 29 having an air outlet facing the transparent plate 20 is fixed to a central portion of each blade upper edge support piece 19. The air inlet of the nozzle 29 and the electromagnetic direction switching valve 25 are fixed. The air discharge port f4 is connected by an air pipe 28b. Therefore, when the output member 21a of the rodless cylinder 21 is moving in the left-right direction b, compressed air is jetted from the air outlet of the cleaning air jet nozzle 29 and blown onto the surface of the transparent plate 20.

  Moreover, each partition wall apparatus 11 with a cleaning function is provided with the blade drive guide means, and this blade drive guide means consists of two technical elements of the drive means 19 and the lift-up means 30.

  More specifically, when the driving means 19 moves the blade 18 in the left-right direction b, the blade 18 is moved further by a specific distance in the left direction b2 than the left end of the transparent plate 20, and the blade 18 is moved to the transparent plate 20 It is to be moved by a specific distance in the right direction b1 further than the right end.

  Then, the lift-up means moves the blade 18 in a direction orthogonal to the partition wall 17 in each of a location further left than the left end of the transparent plate 20 and a location further right than the right end of the transparent plate 20. It is intended to move away from the transparent plate 20 and the partition wall 17.

  The lift-up means 30 can be formed in various ways. In the illustrated example, a pair of upper and lower guide blocks 31a and 31b formed with an inclined guide surface g1 are partitioned at positions near the left and right ends of the transparent plate 20, respectively. A pair of upper and lower sliding contact members 32a and 32b corresponding to the pair of guide blocks 31a and 31b on the left and right sides are provided near the upper and lower ends of the left and right sides of the blade upper edge support piece 19, respectively. When the blade 18 is moved in the left direction b2, the inclined guide surfaces g and g of the left and right pair of guide blocks 31a and 31b and the blade upper edge support are fixed. A pair of upper and lower sliding contact members 32a and 32b on the left side surface of the piece 19 come into contact with each other, and the guide blocks 31a and 31b and the sliding contact members 32a and 32b interact with each other as the blade 18 moves in the left direction b2. In the blade 18 comes to be pushed upward in FIG. 3 away from the transparent plate 20 and the partition wall 17. On the other hand, when the blade 18 is moved in the right direction b1, the pair of upper and lower guide blocks 31a and 31b on the right side and the pair of upper and lower sliding members 32a on the left side surface of the blade upper edge support piece 19 are provided. 32b abuts, and the blade 18 moves away from the transparent plate 20 and the partition wall 17 due to the interaction between the guide blocks 31a and 31b and the sliding contact members 32a and 32b as the blade 18 moves in the right direction b1. 3 is pushed upward in FIG.

  Therefore, the blade drive guide means 19 and 30 are located at positions outside the region of the through-hole wall portion 17a when the blade 18 is viewed from the direction orthogonal to the surface of the transparent plate 20, and the through-hole wall portion 17a and It can be stopped in a state where it is moved to a position separated from the partition wall 17 by a specific distance.

  Further, in the vicinity of the left and right end portions of the transparent plate 20, a position between the left and right pair of upper and lower guide blocks 31a and 31b and the left end of the transparent plate 20, and the right and left pair of guide blocks 31a and 31b and the transparent plate 20 are transparent. Scrapers 33 that scrape off deposits adhering to the front surface h1 and the rear surface h2 of the blade 18 are provided at 17 portions of the partition wall at a position between the right end of the plate 20. The scraper 33 is made of a rod member having a round cross section or a square cross section which is longer than the length of the blade 18, and the bar member 33 is arranged at a distance of at least several mm from the surface of the partition wall 17 in a substantially vertical direction. It is fixed to the partition wall 17 through a support piece, and when the blade 18 is moved in the left-right direction b, the full length portions of the front surface h1 and the rear surface h2 of the front portion of the blade 18 come into contact with each other.

  Here, the relationship among the blade 18, the lift-up means 30, and the scraper 33 will be described in more detail. Now, the drive means 19 is activated, and the blade 18 is moved from the right side of the transparent plate 20 to the left b2 while being pressed against the surface of the transparent plate 20 by the elasticity of the leaf spring members 24, 24, as shown by the solid line in FIG. When the blade 18 reaches the left end of the transparent plate 20, the blade 18 approaches the left scraper 33 and the pair of upper and lower sliding members 32 a and 32 b approach the left upper and lower pair of guide blocks 31 a and 31 b. Is moved leftward from the transparent plate 20, and the pair of upper and lower guide blocks 31a and 31b support and guide the pair of upper and lower sliding contact members 32a and 32b. 3 is moved downward in FIG. 3 so as to be separated from the transparent plate 20 and the partition wall 17, and is held in a state slightly separated from the surface of the partition wall 17. On the other hand, as shown in FIG. 4A, the front face h1 of the blade 18 abuts against the left scraper 33, and in the process of moving the blade 18 in the left direction b2, the blade 18 and the left upper and lower guide blocks 31a and 31b 3 is moved gradually downward from the transparent plate 20 and the partition wall 17 by the interaction of the pair of upper and lower sliding contact members 32a and 32b. At this time, the left scraper 33 pushes the front surface h1 of the blade 18 While the blade 18 is bent so that the degree of bending thereof is increased within the elastic limit, the blade 18 is relatively moved to the front end on the front surface h1 of the blade 18, and in this moving process, the adhering matter attached to the front surface h1 of the blade 18 is scraped off. In addition, when the blade 18 moves in the left direction b1, the blade 18 is separated from the left scraper 33 and becomes free. 4C, and eventually reaches the leftmost position, as shown in FIG. 4C. At the leftmost position, the pair of upper and lower sliding contact members 32a and 32b are provided with a pair of upper and lower left guides. Supported by the inclined guide surfaces g and g of the blocks 31a and 31b, the blade 18 is in a state farthest from the surface of the partition wall 17.

  Conversely, when the blade 18 is moved from the leftmost position to the right direction b1 by the operation of the driving means 19, the blade 18 is moved to the left upper and lower pair of guide blocks 31a and 31b and the left upper and lower pair of sliding contact members 32a and 3b is gradually moved upward in FIG. 3 so as to approach the transparent plate 20 and the partition wall 17, and the rear surface h2 first comes into contact with the left scraper 33 as shown in FIG. As the blade 18 moves in the right direction b1, the blade 18 gradually moves upward in FIG. 3 so as to approach the transparent plate 20 and the partition wall 17, and the left scraper 33 moves to the rear surface h2 of the blade 18. The blade 18 is bent so that the degree of bending thereof is increased within the elastic limit, and the blade 18 is relatively moved on the rear surface h2 of the blade 18 to the tip thereof. When the blade 18 moves in the right direction b1, the blade 18 moves away from the left scraper 33 and becomes free and returns to its flat shape by its own elasticity. The blade 18 reaches the left end of the transparent plate 20, the left and right pair of sliding contact members 32a and 32b are separated from the left and right pair of upper and lower guide blocks 31a and 31b, and the blade 18 is moved rightward b1. At this time, the blade 18 is pressed against the surface of the transparent plate 20 by the elasticity of the leaf spring member 24.

  The related operations of the blade 18, the left lift-up means 30 and the left scraper 33 are as described above, but the related operations of the blade 18, the right lift-up means 30 and the right scraper 33 are symmetrical with the related operations described above. To be done.

  Further, the different color particle presence detection means 12 includes an imaging device provided inside each of the pair of imaging chambers 10A and 10B and a different color particle presence determination unit 34 installed at an appropriate location of the machine body. The imaging device in each imaging chamber includes a camera 35, a background plate 36, a fluorescent lamp 37, and the like, and each camera 35 in the pair of imaging chambers 10A and 10B flows down against the background plate 36 in the imaging chamber on the other side. The granular material w group that falls from the lower end of 2 and flies is imaged through the transmission wall portion 17a, and the fluorescent lamps 37 in the pair of imaging chambers 10A and 10B have a transmission wall in front of and behind the granular material w group that is imaged in this way. Therefore, each camera 35 receives light from the fluorescent lamp 37 transmitted through the granular material w and light from the fluorescent lamp 37 reflected from the granular material w. The different color particle presence determination unit 34 receives the imaging information generated by the camera 35, determines the presence of the different color granular material w1 from the imaging information, and issues a different color particle presence detection signal when determining that the different color granular material w1 exists. To do.

  The external force applying means 10 includes an air injection nozzle 38 disposed below the imaging chambers 10 </ b> A and 10 </ b> B inside the granular material processing chamber 9, and air supplying compressed air from the compressed air source 27 to the nozzle 38. A supply line 28b, an electromagnetic opening / closing valve 39 provided in the middle of the line 28b, and a valve opening / closing control unit 40 for controlling the opening / closing of the electromagnetic opening / closing valve 39 are provided.

  When a different color particle presence detection signal is issued from the different color particle presence determination unit 34, the valve opening / closing control unit 40 energizes the electromagnetic coil of the electromagnetic on / off valve 39 in relation to the different color particle presence detection signal, and the electromagnetic on / off valve 39 Thus, the compressed air from the compressed air source 27 is supplied to the air injection nozzle 38 through the air supply line 28b and the electromagnetic on-off valve 39, and the air injection nozzle 38 is supplied to the different color particle presence detecting means 12. Compressed air is jetted toward the detected different color granular material w1.

  The air flow generated by the jet repels the different color granular material w1 in the granular material w group that falls from the lower end of the falling rod 2 and flies upward and the normal granular material w in the vicinity thereof, and repels in this way. The different color granular material w1 and the like that have been skipped fall into the defective product container 4b through the upper flight trajectory a2, and the other granular materials w fall into the good product container through the normal flight trajectory a1. The granular material w in the non-defective product receiving portion 4a is transferred into the non-defective product tank 102, and the different color granular material w1 in the defective product storing portion 4b is transferred into the defective product tank 103.

  Further, the ventilation means 14 includes an air supply window j1 formed in the upper part of the lower casing 15b, an exhaust port j2 formed in the lower part of the lower casing 15b, and an inside of the granular material processing chamber 9 from the exhaust port j2 through the exhaust pipe 41. The ventilator 42 flows the air or the like to the atmosphere side.

  Next, the usage example and effect | action of the partition wall apparatus 11 with a cleaning function are demonstrated. When the granular material w is color-sorted by the color sorter, the blade 18 is positioned at the leftmost position or the rightmost position of the moving range in the left-right direction b. In this state, the blade 18 is located outside the surface range of the light transmissive wall portion 17a when viewed from the direction orthogonal to the partition wall 17, so that the cameras 35 and 35 pass through the light transmissive wall portion 17a. The blade 18 does not become a hindrance when imaging the granular material w group in the granular material processing chamber 9, and the light from the fluorescent lamp 37 does not directly strike the blade 18 through the translucent wall portion 17a. The blade 18 is prevented from being deteriorated by ultraviolet rays emitted from the blade 37, and the blade 18 is in a free state away from the transparent plate 20 and the partition wall 17, so that internal stress is hardly generated and the dynamics of the material. Is prevented.

  In addition, when the granular material w to be processed by the color sorter is brown rice that has just been removed by the rice huller, a lot of rice cake enters the granular material processing chamber 9 together with the brown rice. The soot that has entered is discharged to the outside by the ventilation means 14, but some of the soot adheres to the surface of the translucent wall portion 17a on the side of the granular material processing chamber 9 and accumulates over time. However, since the imaging chambers 10A and 10B are surrounded by the partition wall device 11 with the cleaning function and the casing 16, dust such as soot does not enter and is maintained in a clean state.

  If soot adheres to or accumulates on the translucent wall portion 17a beyond a certain level, the transmission performance of the translucent wall portion 17a deteriorates, and the light from the fluorescent lamp 37 in the imaging chambers 10A and 10B is transferred to the particulate matter processing chamber 9. In addition to not sufficiently illuminating the granular material w group, the light from the granular material w group is difficult to reach the cameras 35 and 35, so that the imaging by the cameras 35 and 35 is not performed in a high sensitivity state. Sorting and removing the different color granular material w1 is not performed accurately.

  Therefore, the driving means 19 is operated before the deposition exceeds a certain level. When the driving means 19 is operated, the supply of the brown rice w from the feeder 1 of the color sorter to the falling rice cake 2 is stopped.

  Under this stop state, the drive means 19 is operated. If the electromagnetic direction switching valve 25 is now in a non-energized state, the blade 18 is positioned at the leftmost position and stopped. When starting the operation, the non-energized electromagnetic direction switching valve 25 is turned on by operating a switch of a control device (not shown). As a result, the blade 18 is moved in the right direction b1 by the rodless cylinder 21 and scrapes and the like adhering to the rear surface h2 of the blade 18 are scraped off by the scraper 33 before reaching the transparent plate 20. It moves in a state of being pressed against the surface of the transparent plate 20, and the wrinkles and the like adhering to the surface of the transparent plate 20 are removed by pressing on the rear surface h2 to be peeled off and swept to the right side. The air is sprayed from the transparent plate 20 to blow off the soot and the like peeled off from the transparent plate 20 to the outside of the transparent plate 20, so that the surface of the transparent plate 20 is cleaned cleanly. In addition, the soot blown off in this way falls to the lower part in the granular material processing chamber 9, and is discharged | emitted by the ventilator 14 outside.

  When the blade 18 reaches the right end of the surface of the transparent plate 20, the scissors or the like that have been scraped off are attached to the tip of the rear surface h2 of the blade 18, but the blade 18 is further moved in the right direction b1, The right scraper 33 scrapes off and removes the soot and the like adhering to the rear surface h2 of the blade 18. The scraped scraps and the like of the right scraper 33 fall near the scraper 33, but fall to the right side of the translucent wall portion 17a, and therefore do not fall directly on the translucent wall portion 17a. The light transmission performance of 17a is not impaired, and air is blown off from the surface of the partition wall 17 by the air injected from the cleaning air injection nozzle 29, so that accumulation of soot and the like proceeds excessively on the surface of the partition wall 17. There is nothing to do. It should be noted that the fact that the left and right scrapers 33 are separated from the partition wall 17 is useful for blowing away the scum scraped off by the scraper 33 with air.

  After the blade 18 reaches the rightmost position, the electromagnetic direction switching valve 25 is again de-energized by the automatic operation of a control device (not shown), whereby the blade 18 is moved leftward by the rodless cylinder 21. The scraper 33 on the right side scrapes off the wrinkles adhering to the front surface h1 of the blade 18 before reaching the transparent plate 20, and the blade 18 is pressed against the surface of the transparent plate 20 on the transparent plate 20. In this state, the soot and the like adhering to the transparent plate 20 during the movement is pushed away by the front surface h1 and removed so as to be swept to the left side. On the other hand, air is injected from the cleaning air injection nozzle 29. Then, the wrinkles peeled off from the transparent plate 20 are blown off the surface of the transparent plate 20, so that the surface of the transparent plate 20 is cleaned cleanly.

  When the blade 18 reaches the left end of the transparent plate 20, the scraped crease or the like is attached to the front surface h1 of the blade 18, but the left scraper is moved further by moving the blade 18 in the left direction b2. 33 scrapes and removes the soot and the like adhering to the front surface h1 of the blade 18. The scraps and the like scraped by the left scraper 33 fall in the vicinity of the scraper 33. However, as in the case of the right scraper 33, they do not fall directly on the translucent wall portion 17a. The optical performance is not impaired, and the air sprayed from the cleaning air jet nozzle 29 is blown off from the surface of the partition wall 17 so that accumulation of soot and the like does not proceed excessively on the surface of the partition wall 17. .

  Thus, when the blade 18 reaches the leftmost position, the movement of the blade 18 in the left direction is restricted and stopped by the restricting action of an appropriate stopper, and the next operation is prepared.
