  FIG. 1 is a diagram illustrating an example of a continuous surface treatment facility to which the sample collection device 10 of the present embodiment is applied. As the continuous surface treatment facility in FIG. 1, a continuous electrotin plating line facility may be mentioned. In the continuous surface treatment facility as shown in FIG. 1, the steel plate 44 paid out from the payoff reel 42 runs on the vertical looper device 30 provided on the upstream side of the electroplating tank 40. The steel plate 44 that has traveled through the vertical looper device 30 is introduced into the electroplating tank 40.

  In the electroplating tank 40, for example, an Sn plating layer is formed on the surface of the steel plate 44. After the Sn plating layer is formed, chemical conversion treatment such as chromate treatment may be performed. The steel plate 44 (plated steel plate 44) on which the Sn plating layer is formed and subjected to the chemical conversion treatment runs on the vertical looper device 32 provided on the downstream side of the electroplating tank 40. The plated steel plate 44 that has traveled through the vertical looper device 32 is taken up by a tension reel 48. A sample collection device 10 is provided on the downstream side of the vertical looper device 32. The sample collection device 10 collects a sample of the plated steel plate 44 (hereinafter referred to as “steel plate sample”) that has traveled through the vertical looper device 32 at a predetermined frequency.

  The continuous surface treatment facility shown in FIG. 1 includes vertical looper devices 30 and 32 on the upstream and downstream sides of the electroplating tank 40. For this reason, in order to weld another steel plate 44 that follows the tail end of the preceding steel plate 44, the traveling of the steel plate 44 is interrupted between the vertical looper device 30 and the payoff reel 42, and sampling is performed. The plating treatment of the steel plate 44 can be continued while the steel plate sample of the portion where the steel plate 44 is welded is collected in the apparatus 10.

  FIG. 2A and FIG. 2B are diagrams for explaining a procedure for collecting a sample by the sample collecting apparatus 10. The steel plate 44 that has traveled through the vertical looper device 32 passes through the bridle roll 45 and is then taken up by the tension reel 48a. A sample collection device 10 is provided between the bridle roll 45 and the tension reel 48a. The sample collection device 10 is a device that collects a sample of the steel plate 44 (steel plate sample 46), which is necessary for quality inspection or testing, for example. A rotary shearing machine 50 for cutting the steel plate 44 is provided on the upstream side of the sample collection device 10.

  When collecting a steel plate sample, first, the steel plate 44 is cut using a rotary shearing machine 50 as shown in FIG. In the rotary shearing machine 50, the traveling steel plate 44 is cut into a predetermined length to obtain a plurality of steel plate samples 46. The cut steel plate sample 46 is collected by the sample collection device 10 after traveling on the magnet conveyor 52 as shown in FIG.

  FIG. 3A and FIG. 3B are diagrams illustrating a procedure for collecting a sample by the sample collection device 10. When the necessary number of steel plate samples 46 are collected, the cutting of the steel plate 44 by the rotary shearing machine 50 is stopped as shown in FIG. After the cutting is stopped, the steel plate 44 is taken up by the tension reel 48b as shown in FIG. While the steel plate 44 is being wound by the tension reel 48b, the steel plate 44 wound on the tension reel 48a can be shipped as a product. The continuous surface treatment facility of FIG. 1 includes the vertical looper device 32 on the upstream side of the bridle roll 45, so that the plating treatment of the steel plate 44 is continued even while the sample collection device 10 is collecting a sample. It can be carried out.

  FIG. 4 is a diagram showing an outline of the sample collection device 10. A plurality of steel plate samples 46 are conveyed to the sample collection device 10 by the magnet conveyor 52 in the X direction (one direction) of FIG. The steel plate sample 46 conveyed in one direction is collected by the sample collection device 10.

  The sample collection device 10 is in contact with the tip of the steel plate sample 46 and sandwiches the steel plate sample 46 in the width direction of the steel plate sample 46 with the front wall 16 stopping the movement of the steel plate sample 46 in one direction. It has a pair of side walls 12 and 12 that can adjust the interval according to the width, an interval adjusting unit 11 that adjusts the interval between the pair of side walls 12 and 12, and a flooring 64 on which the steel plate sample 46 is placed. Between the pair of side walls 12, 12 using the transporting unit 60 that transports the material 64 and the steel plate sample 46 placed on the flooring 64 in the Y direction (the direction perpendicular to the X direction), and the flooring 64. Are provided with a floor forming section 20 for forming a floor having a length corresponding to the width of the steel plate sample 46.

  The shape of the front wall 16 is not particularly limited as long as the shape of the front wall 16 is such that it can contact the tip of the steel plate sample 46 conveyed in one direction and stop the movement of the steel plate sample 46. The front wall 16 may have a shape that contacts a part of the tip of the steel plate sample 46. By collecting the steel plate sample 46 so that the front end of the steel plate sample 46 and the front wall 16 are in contact with each other, the steel plate sample 46 can be collected in the length direction (X direction).

  The shape of the side wall 12 is not particularly limited as long as it is a shape capable of coming into contact with the side portion of the steel plate sample 46. For example, as shown in FIG. 4, the interval between the upstream side walls 12, 12 in one direction may be larger upward than the interval between the downstream side walls 12, 12. Thereby, it can fully suppress that the front-end | tip of the steel plate sample 46 and the side end surface or upper end surface of the side wall 12 contact.

  The interval between the pair of side walls 12 and 12 can be adjusted by the interval adjusting unit 11. The distance between the pair of side walls 12 and 12 is preferably adjusted by the distance adjusting unit 11 so as to match the width L1 of the steel plate sample 46 or slightly larger than the width L1. The width L1 of the steel plate sample 46 is the length of the steel plate sample 46 in the Y direction of FIG. 4, and the width direction of the steel plate sample 46 is the Y direction of FIG. By adjusting the interval between the pair of side walls 12 and 12 by the interval adjustment unit 11, the plurality of steel plate samples 46 can be collected so that the plurality of steel plate samples 46 are aligned in the width direction (Y direction).

  The sample collection device 10 is provided so as to face the front wall 16 and includes a nozzle-like air supply unit 19 that discharges air from the rear end side of the steel plate sample 46 toward the back surface of the steel plate sample 46 that has been conveyed. Have. It is possible to suppress the occurrence of wrinkles on the surface of the steel plate sample 46 by slowing the collision speed between the steel plate samples 46 stacked one above the other due to the buoyancy caused by the air discharged from the air supply unit 19. The discharge of air from the air supply unit 19 may be performed continuously or intermittently every time the steel plate sample 46 is collected. There may be one air supply unit 19 or three or more. Further, the air supply unit 19 may be embedded in the rear wall.

  The sample collection device 10 has a rear wall 18 that faces the front wall 16 and is provided so as to be able to contact the rear end of the steel plate sample 46. The shape of the rear wall 18 is not particularly limited, and may be a shape that can contact a part of the rear end of the steel plate sample 46. By providing such a rear wall 18, the steel plate sample 46 that has been conveyed abuts against the front wall 16 and then rebounds from the front wall 16. (X direction) can be more accurately aligned. Moreover, the buoyancy effect | action of the air from the air supply part 19 is exhibited more effectively, and it can suppress further that wrinkles arise on the surface of a steel plate sample. The space | interval adjustment part 11 is connected with a pair of side walls 12 and 12 via the connection member 12a, respectively.

  FIG. 5 is a schematic view of the sample collection device 10 as viewed in the horizontal direction. As shown in FIG.4 and FIG.5, the space | interval adjustment part 11 of the sample collection device 10 has the motor 11a and the axis | shaft 11b connected with the motor 11a. The shaft 11 b is fitted to a connecting member 12 a that is connected to the side wall 12. Complementary threads are formed on the shaft 11b and the connecting member 12a. The shaft 11b is a male screw, and the connecting member 12a is a female screw. The screw thread of the shaft 11b is formed so as to be in the opposite direction with the central part of the pair of side walls 12, 12 (the pair of connecting members 12a, 12a) as a boundary. That is, one connecting member 12a has a normal thread, and the other connecting member 12a has a reverse thread.

  By rotating the motor 11a, the shaft 11b rotates. As the shaft 11b rotates, the pair of connecting members 12a and the pair of side walls 12 and 12 move in opposite directions along the shaft 11b. In this way, the distance between the pair of side walls 12 is adjusted. The interval adjusting unit 11 is not limited to the motor 11a and the shaft 11b. For example, you may adjust the space | interval of a pair of side walls 12 and 12 with an actuator. Further, the interval adjusting portion 11 may be directly fitted to the side wall 12 without providing the connecting member 12a.

  The conveyance unit 60 of the sample collection device 10 includes a floor material 64, a chain 62 provided with the floor material 64 in part, and four sprockets 67 that drive the chain 62. The sprocket 67 is connected to a motor or the like (not shown). The transport unit 60 is configured to be able to rotate the chain 62 clockwise or counterclockwise in FIG. 5 by rotating the sprocket 67 by rotational driving of a motor or the like.

  In FIG. 5, a belt-like floor material 64 is attached to the upper chain 62 on the chain 62. On the other hand, the floor material 64 is not attached to the left and right chains 62 and the lower chain 62. When the chain 62 is rotated, the floor material 64 moves in a substantially horizontal direction as the chain 62 moves. As the flooring 64, for example, a rectangular steel plate or the like is used. As the flooring 64, for example, one having a width slightly narrower than the pitch of the chain 62 is used.

  The transport unit 60 having the chain 62 and the floor material 64 attached thereto extends below the pair of side walls 12 and 12 in a direction perpendicular to the one direction (Y direction). Therefore, the transport unit 60 can transport the steel plate sample 46 placed on the floor material 64 in the Y direction.

  The floor forming unit 20 includes an elevating mechanism 28 that raises or lowers the floor material 64 with respect to the pair of side walls 12 and 12, and a length adjusting mechanism 22 that adjusts the length of the floor. The elevating mechanism 28 has a pair of actuators 24, 24 and a pair of connecting members 24 a connected to the pair of actuators 24, 24. The connecting member 24 a connects the actuator 24 to the upper sprocket 26 and the lower sprocket 25.

  The length adjusting mechanism 22 has a motor 22a and a shaft 22b connected to the motor 22a. The shaft 22b is fitted to the pair of connecting members 24a and 24a. The pair of connecting members 24a, 24a extend in the vertical direction, and an upper sprocket 26 and a lower sprocket 25 are attached to the upper and lower ends of the connecting member 24a, respectively. Since the length of the connecting member 24 a in the vertical direction is longer than the height of the transport unit 60, at least one of the upper sprocket 26 and the lower sprocket 25 is always in contact with the chain 62.

  A fixed sprocket 27 is provided on the upper chain 62 so as to be adjacent to the upper sprocket 26. Two fixed sprockets 27 are provided so as to sandwich a pair of upper sprockets 26 from both sides. The floor forming unit 20 raises the upper sprocket 26 by the lifting mechanism 28. The upper sprocket 26 contacts the upper chain 62 from below and urges the chain 62 upward. The fixed sprocket 27 contacts the chain 62 biased upward by the upper sprocket 26 from above, and biases the chain 62 downward. As a result, the chain 62 and the plurality of floor materials 64 between the pair of upper sprockets 26 are separated from the chain 62 and the floor material 64 outside the pair of upper sprockets 26, that is, on the fixed sprocket 27 side of the upper sprocket 26. Is also lifted, and the floor 14 composed of a plurality of flooring materials 64 is formed.

  The shaft 22 b of the length adjusting mechanism 22 is fitted to a connecting member 24 a that is connected to the actuator 24. The shaft 22b and the connecting member 24a are formed with complementary threads. The shaft 22b is a male screw, and the connecting member 24a is a female screw. The screw thread of the shaft 22b is formed in the opposite direction with the central portion between the pair of connecting members 24a and 24a as a boundary. That is, one connecting member 24a has a normal thread, and the other connecting member 24a has a reverse thread.

  The shaft 22b is rotated by rotationally driving the motor 22a of the length adjusting mechanism 22. An actuator 24 and an upper sprocket 26 are attached to the pair of connecting members 24a and 24a, respectively. By rotating and driving the motor 22a, the shaft 22b rotates, and the distance between the pair of connecting members 24a and 24a and the pair of upper sprockets 26 and 26 is changed. Thereby, the length of the floor 14 composed of a plurality of floor materials 64 can be adjusted. The length of the floor 14 is adjusted by changing the number of floor materials 64 constituting the floor 14.

  FIG. 6 is a schematic view of the sample collection device 10 when viewed in the horizontal direction, similarly to FIG. 5. Two fixed sprockets 29 are provided so as to sandwich the pair of lower sprockets 25 from both sides. In FIG. 6, the elevating mechanism 28 is lowered so that the upper sprocket 26 and the chain 62 are not in contact with each other, and the floor material 64 that constitutes the floor 14 on which the steel plate sample 46 is placed is a floor that does not constitute the floor 14. It is flat with the material 64.

  On the other hand, the lower sprocket 25 contacts the lower chain 62 in FIG. 6 from above and urges the chain 62 downward. The fixed sprocket 29 contacts the chain 62 from below and urges the chain 62 upward. As a result, the chain 62 between the pair of lower sprockets 25 is lowered from the chain 62 located on the fixed sprocket 29 side relative to the lower sprocket 25.

  5 collects a steel plate sample 46 having a width L1. The method of collecting the steel plate sample 46 will be described below while detailing the operation of each part when the steel plate sample 46 is collected by the sample collecting device 10.

  In the method of collecting the steel plate sample 46 having the width L1, a part of the floor material 64 is raised by the lifting mechanism 28 to form the floor 14, and the length of the floor 14 is adjusted by the length adjusting mechanism 22. The second step, the third step of adjusting the interval between the pair of side walls 12 and 12 by the interval adjusting unit 11 according to the width L1 of the steel plate sample 46, and the steel plate sample 46 conveyed in one direction (X direction) The front wall 16 is brought into contact with the front wall 16, stopped between the pair of side walls 12, 12, and the steel plate sample 46 is placed on the floor 14. , 12, a sixth step of lowering the steel plate sample 46 and the floor 14 on which the steel plate sample 46 is placed with respect to the pair of side walls 12, 12, and the steel plate sample 46. 60 means one direction is vertical Has a seventh step of conveying (Y-direction), the. The first process, the second process, and the third process will be described with reference to FIG.

  In the first step, a part of the floor material 64 is raised by the elevating mechanism 28 to form the floor 14. An upper sprocket 26 is attached to the outside of the pair of actuators that are the lifting mechanism 28 via a connecting member 24a. The upper sprocket 26 lifts a part of the chain 62 extending in the horizontal direction and a plurality of strip-like floor materials 64 arranged side by side in the longitudinal direction of the chain 62 on the part. The floor 14 is formed by the plurality of raised strip-like floor materials 64. The floor 14 is inserted between the pair of side walls 12 installed above the floor forming unit 20 by the lifting mechanism 28.

  In the second step, the length of the floor 14 is adjusted by the length adjusting mechanism 22 in accordance with the width L1 of the steel plate sample 46. That is, the motor 22a of the length adjusting mechanism 22 is driven to change the interval between the pair of connecting members 24a. By changing the interval of the connecting member 24a, the interval of the upper sprocket 26 attached to the connecting member 24a is changed, and the length of the floor 14 can be adjusted. The length of the floor 14 is preferably substantially the same as the width L1.

  In the third step, the interval adjusting unit 11 adjusts the interval between the pair of side walls 12 and 12 according to the width L1 of the steel plate sample 46. By adjusting the distance between the pair of side walls 12, 12, the steel plate sample 46 placed on the floor 14 can be restrained in the width direction and can be prevented from being displaced in the width direction. The distance between the pair of side walls 12, 12 may be the same as the width L1 or may be slightly larger (for example, 1.0 × L1 to 1.05 × L1).

  Through the above steps, the recessed space 70 for accommodating the steel plate sample 46 is formed. That is, the floor 14, together with the pair of side walls 12, 12, the front wall 16, and the rear wall 18, forms a recessed space 70 that accommodates the steel plate sample 46. At this time, the floor 14 constitutes the bottom surface of the recessed space 70. In addition, it is not essential to perform a 1st process, a 2nd process, and a 3rd process in the above-mentioned order. For example, it may be performed in the order of the first step, the third step, and the second step, or may be performed in the order of the third step, the second step, and the first step. Further, these three steps may be performed simultaneously. The order can be appropriately set according to the positional relationship between the pair of side walls 12 and 12 and the pair of upper sprockets 26 and 26.

  In the fourth step, the front end of the steel plate sample 46 conveyed in one direction (perpendicular to the paper surface of FIG. 5) is brought into contact with the front wall 16, and the steel plate sample 46 is stopped between the pair of side walls 12, 12. The steel plate sample 46 is placed on the floor 14. The steel plate samples 46 that are intermittently conveyed are sequentially accommodated in the recessed space 70. At this time, air may be discharged from the air supply unit 19 to the back surface of the steel sheet sample 46 conveyed to the recessed space 70. By the buoyancy action of air, the collision speed between the steel plate sample 46 already accommodated in the recessed space 70 and the steel plate sample 46 accommodated thereon is slowed to suppress the generation of wrinkles on the surface of the steel plate sample 46. can do.

  In the present embodiment, in the third step, since the distance between the pair of side walls 12 and 12 is adjusted according to the width L1 of the steel plate sample 46, the side portion of the steel plate sample 46 is brought into contact with the side wall 12. A steel plate sample 46 can be collected on the floor 14. For this reason, on the floor 14, it is suppressed that the some steel plate sample 46 shifts | deviates to the width direction. Therefore, a plurality of steel plate samples 46 can be placed on the floor 14 in a state where the positional deviation in the width direction is sufficiently suppressed. Further, since air circulation in the gap between the side wall 12 and the steel plate sample 46 and in the gap between the front wall 16 and the rear wall 18 and the steel plate sample is reduced, the buoyancy action by the air from the air supply unit 19 is sufficiently exhibited. Thus, the collision speed between the steel plate samples 46 can be sufficiently slowed. As a result, the generation of wrinkles on the surface of the steel plate sample 46 can be sufficiently suppressed. When the predetermined number of steel plate samples 46 are placed on the floor 14 in the fourth step, the fifth step is performed.

  FIG. 6 is a schematic view of the sample collection device 10 when viewed in the horizontal direction, similarly to FIG. 5. With reference to FIG. 6, the fifth step, the sixth step, and the seventh step will be described.

  In the fifth step, the gap between the pair of side walls 12, 12 is widened by the gap adjusting unit 11 (arrow 1 in FIG. 6). Specifically, the motor 11a is driven to rotate the shaft 11b in the opposite direction to the third step. As a result, the pair of side walls 12 and 12 that have been in contact with the side portions of the steel plate sample 46 are separated from the steel plate sample 46, and the restraint of the steel plate sample 46 can be released.

  In the sixth step, the steel plate sample 46 and the floor 14 on which the steel plate sample 46 is placed are lowered by the elevating mechanism 28 with respect to the pair of side walls 12 and 12 (arrow 2 in FIG. 6). That is, the actuator which is the raising / lowering mechanism 28 is driven, and the connection members 24a and 24a and the upper sprockets 26 and 26 attached thereto are lowered. When the upper sprockets 26 and 26 are separated from the chain 62, the height of the floor material 64 constituting the floor 14 and the height of the other floor material 64 are aligned, and the upper chain 62 and the floor material 64 become flat. .

  When the connecting members 24 a and 24 a are lowered by the elevating mechanism 28, the lower sprocket 25 attached to the lower end of the connecting member 24 a comes into contact with the chain 62 extending below the floor forming portion 20. When the lower sprocket 25 pushes down a part of the lower chain 62, the upper sprocket 26 can be lowered to a position where it does not contact the upper chain 62.

  In the seventh step, the sheet is conveyed in the direction perpendicular to the one direction (the direction of arrow 3 in FIG. 6) by the conveyance unit 60. The steel plate sample 46 is transported together with the floor 14 (floor material 64) on which the steel plate sample 46 is placed. The steel plate sample 46 transported to a predetermined position is transported by other transport means and can be used for quality inspection or testing.

  Next, with reference to FIGS. 7 and 8, a method of collecting a steel plate sample 46a having a width L2 smaller than the width L1 will be described. 7 and 8 are schematic views when the sample collection device 10 is viewed in the horizontal direction, similarly to FIGS. In this method, the first step of forming the floor 14 by raising a part of the floor material 64 by the lifting mechanism 28 is performed in the same manner as the method of collecting the steel plate sample 46 having the width L1 (arrow in FIG. 7). 1). Next, a second step of adjusting the length of the floor 14 by the length adjusting mechanism 22 is performed. The steel plate sample 46 a has a smaller width than the steel plate sample 46. For this reason, in a 2nd process, the space | interval of a pair of connection member 24a, 24a is narrowed by the length adjustment mechanism 22 (arrow 2 in FIG. 7). Thereby, the space | interval of the upper sprockets 26 and 26 is narrowed, and the length of the floor | bed 14 can be adjusted to the length according to the width | variety L2 of the steel plate sample 46a.

  When the length of the floor 14 is adjusted, the third step of adjusting the distance between the pair of side walls 12 and 12 by the distance adjusting unit 11 is performed according to the width L2 of the steel plate sample 46a (arrow 3 in FIG. 7). By the first step, the second step, and the third step, the recessed space 70 for collecting the steel plate sample 46a having the width L2 can be formed.

  When the recessed space 70 corresponding to the width L2 of the steel plate sample 46a is formed, the front end of the steel plate sample 46a conveyed in one direction is brought into contact with the front wall 16 so that the steel plate sample 46a is placed between the pair of side walls 12 and 12. A fourth step is performed in which the steel plate sample 46a is placed on the floor 14 after stopping. After the fourth step, the steel plate sample 46a and the steel plate are compared with the fifth step (arrow 1 in FIG. 8) in which the gap between the pair of side walls 12 and 12 is increased by the gap adjusting unit 11 and the pair of side walls 12 and 12. A sixth step (arrow 2 in FIG. 8) for lowering the floor 14 on which the sample 46a is placed, and a seventh step (in FIG. 8) in which the steel plate sample 46a is transported in a direction perpendicular to one direction by the transport unit 60. , Arrow 3).

  As described above, the sample collection device 10 smoothly adjusts the length of the floor 14 and the distance between the pair of side walls 12 and 12 according to the width even if the width of the steel plate sample is different as in the steel plate samples 46 and 46a. can do. And the position shift of the steel plate samples 46 and 46a can be suppressed, and the positions of the plurality of steel plate samples 46 and 46a can be aligned and collected. Therefore, according to the sample collection device 10 and the sample collection method of the present embodiment, it is easy to collect the steel plate samples 46 and 46a having different widths, and workability can be improved.

  Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments. Continuous surface treatment equipment is not limited to continuous electrotin plating line equipment, but for example, continuous electrotin plating line equipment, continuous hot dip galvanizing line equipment, continuous annealing line equipment, etc. Any facility that performs processing may be used. Moreover, although the belt-shaped floor material 64 provided on the chain 62 and the chain 62 has been described as the transport unit 60 in the above-described embodiment, the transport unit 60 may be a belt. In this case, a pulley can be used instead of the sprocket.

  According to the present invention, it is possible to provide a sample collection device and a sample collection method capable of easily collecting a steel plate sample and improving workability.
