Description

  The present invention relates to a sample collection device and a sample collection method.

  In a steel sheet winding device, when a coil to be wound changes, a sample plate is collected to check the amount of plating, the amount of surface coating oil, and the like. In a snip shear method known as one of sample collection methods (a shear that performs only reel switching cutting), a steel plate is manually cut from a wound coil to collect the sample plate. However, such a human-powered cutting operation tends to increase the working time.

  In order to improve workability when collecting sample plates, a method of cutting a steel plate using a shearing machine and dropping a plurality of sample plates of about 0.6 to 1 m into buckets on the upstream side of the reel is known. Yes. For example, Patent Document 1 proposes a technique in which, among sample materials and scrap materials obtained by cutting a steel plate, the sample material is decelerated with a chute and collected in a sample bucket.

  Patent Document 2 proposes a technique in which a shearing machine dedicated to extraction and removal of samples and crops is provided on the downstream side of the winding device, and the samples and crops are sorted and stored in buckets.

JP 2010-253589 A JP-A-6-537

  However, as described above, if the sample plate that is continuously conveyed by a conveyor or the like is collected in a container such as a bucket as it is, the sample plate will collide with the inner wall surface of the container, and the sample plate will be wrinkled and broken. There is a concern to do. Further, if a chute for decelerating the sample plate or a shearing machine (shear) dedicated to removal is provided, there is a concern that the space required for installation of the apparatus increases and the apparatus configuration becomes complicated.

  Therefore, an object of the present invention, in one aspect, is to provide a sample collection device capable of simplifying the device configuration and sufficiently suppressing the occurrence of wrinkles and folds in the sample plate. In another aspect, an object of the present invention is to provide a sample collection method capable of simplifying an apparatus configuration and sufficiently suppressing generation of wrinkles and creases in a sample plate.

  The present invention, in one aspect, is provided with a plurality of reels for winding a steel plate and a shear on the upstream side of the reel, and is a sample collecting device for collecting a sample plate by cutting the steel plate when switching the reels, The first conveyor for conveying the steel plate and the sample plate wound around the reel, and the steel plate and the sample plate are distributed so that the steel plate and the sample plate are respectively conveyed to the second conveyor downstream of the reel and the first conveyor. And a deflector roll, and the second conveyor provides a sample collecting device configured to stop the sample plate after the sample plate is transported.

  The above-described sample collection device includes a deflector roll that sorts the steel plate and the sample plate so that the steel plate and the sample plate are respectively conveyed to the reel and the second conveyor. The second conveyor on which the sample plate is conveyed is configured to stop with the sample plate placed thereon. For this reason, a sample board can be collect | recovered on a 2nd conveyor by stopping a 2nd conveyor in the state which mounted the sample board, without collect | recovering a sample board to a container etc. As a result, damages such as wrinkles and breaks that occur in the sample plate can be sufficiently suppressed. Further, the sample plate can be easily collected without installing a chute below the conveyor or providing a shearing machine dedicated to removal. Therefore, the apparatus configuration can be simplified.

  The sample collection device is provided on the upper side of the second conveyor, and includes a third conveyor that sequentially conveys a plurality of sample plates to the second conveyor while adsorbing the upper surface of the sample plate, and more than the first conveyor and the third conveyor. By lowering the conveying speed of the second conveyor, the third conveyor is transferred to the rear end of the front sample plate placed on the second conveyor from the rear of the sample plate. It is preferable that the two are stacked.

  While providing the said 3rd conveyor, by making the conveyance speed of a 2nd conveyor slower than a 1st conveyor and a 3rd conveyor, a some sample board can be piled up and mounted on a 2nd conveyor. Accordingly, the length of the second conveyor can be shortened to shorten the length of the installation space for the sample collection device.

  The sample collection device may include a detection unit that detects the sample plate, and a control unit that stops the second conveyor with the sample plate placed on the basis of a signal from the detection unit. Thereby, the sample plate and the steel plate can be easily and more reliably distributed by the deflector roll.

  The sample collection device may include a container for collecting scrap pieces included in the sample plate on the downstream side of the second conveyor. Thus, after removing a part of the plurality of sample plates placed on the second conveyor, the second conveyor is operated again, and the scrap pieces remaining on the second conveyor are easily collected in a container.

And a step of distributing the steel plate and the sample plate, and a step of stopping the second conveyor while the sample plate is placed after the sample plate is conveyed by the second conveyor.

  The above-described sample collection method includes a step of distributing the steel plate and the sample plate so that the steel plate and the sample plate are respectively conveyed to the reel and the second conveyor. And a 2nd conveyor stops in the state which mounted the sample board, after conveying the distributed sample board. Therefore, the sample plate can be collected on the second conveyor without being collected in a container or the like. As a result, damage such as wrinkles and creases generated in the sample plate due to the collision between the sample plate and the container can be sufficiently suppressed. Further, the sample plate can be easily collected without installing a chute below the conveyor or providing a shearing machine dedicated to removal. Thus, according to the above-described sample collection method, a sample plate having excellent quality can be easily collected using a simple sample collection device.

  Prior to the step of stopping the second conveyor, the transport speed of the second conveyor is set above the transport speed of the first conveyor and the second conveyor, and the upper surface of the sample plate is adsorbed to the second conveyor. Sample transported from the rear of the sample plate to the rear end of the front sample plate placed on the second conveyor by making it slower than the transport speed of the third conveyor that sequentially transports the plurality of sample plates You may have the process of pile | stacking and mounting the front-end | tip part of a board.

  By having such a process, a plurality of sample plates can be stacked and placed on the second conveyor. Accordingly, the length of the second conveyor can be shortened to shorten the length of the installation space for the sample collection device.

  In the step of stopping the second conveyor, the second conveyor may be stopped with the sample plate placed on the basis of a signal from a detection unit that detects the sample plate. Thereby, the sample plate and the steel plate can be easily and reliably distributed.

  In the sample collection method described above, the plurality of sample plates on the second conveyor may include scrap pieces. In this case, in the step of stopping the second conveyor, after the sample plate other than the scrap pieces is collected from the stopped second conveyor, the second conveyor is operated to remove the scrap pieces remaining on the second conveyor. A step of collecting in a container provided on the downstream side of the second conveyor may be provided. As a result, the scrap pieces can be easily collected in the container.

FIG. 4 is a diagram for explaining one step of the sample collection method using the sample collection device according to the embodiment.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings depending on cases. In the drawings, the same or equivalent elements are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 is a schematic diagram of a sample collection device 100. The sample collection device 100 includes a plurality of reels 30 and 32 for winding the steel plate 50, and a drum shear (rotary shear machine) 22 that cuts the steel plate 50 on the upstream side of the reels 30 and 32. FIG. 1 shows a state in which the steel plate 50 is wound around the reel 30 in the sample collection device 100. The sample collection device 100 is configured to collect a sample plate when switching a reel around which the steel plate 50 is wound from the reel 30 to the reel 32 or from the reel 32 to the reel 30.

  The sample collection device 100 is provided on the downstream side of the first conveyors 11a, 11b, and 11c that convey both the steel plate 50 and the sample plate wound around the reel 30 (32), and the first conveyors 11a, 11b, and 11c. After the sample plate is transported, the second conveyor 12 configured to stop with the sample plate placed thereon is disposed upstream of the reel 30 (32) and the second conveyor 12, and the steel plate 50 and the sample A deflector roll 14 a (14 b) that distributes the transport destination of the plate to the reel 30 (32) and the second conveyor 12 is provided.

  The sample collection device 100 includes a third conveyor 13 that sequentially conveys the sample plate to the second conveyor 12 while adsorbing the upper surface of the sample plate above the second conveyor 12 and the deflector roll 14a (14b). By making the conveyance speed of the second conveyor 12 slower than the first conveyors 11 a, 11 b, 11 c and the third conveyor 13, the third conveyor 13 is a front sample plate placed on the second conveyor 12. A plurality of sample plates can be placed on the second conveyor 12 such that the front end portion of the sample plate conveyed from the rear of the sample plate overlaps the rear end portion.

  The sample collection device 100 includes a detection unit 60 that detects a sample plate, and a control unit 70 that stops the second conveyor 12 with the sample plate placed on the basis of a signal from the detection unit 60. The control unit 70 includes, for example, a main storage device such as a CPU, a ROM, and a RAM, an input device such as a keyboard and a mouse, an output device such as a display, a network card for transmitting and receiving signals to and from the detection unit 60, and the like. It can be configured as a normal computer system including a communication module, an auxiliary storage device such as a hard disk.

  For example, when the detection unit 60 detects a sample plate, a detection signal is input from the detection unit 60 to the control unit 70. The control unit 70 counts the number of detection signals output from the detection unit 60. Thus, the control unit 70 calculates the number of sample plates supplied to the second conveyor 12. When the number of sample plates reaches a predetermined number and the final sample plate or scrap piece passes, the operation of the second conveyor 12 is stopped by a control signal from the control unit 70, for example. In this way, the operation of the second conveyor 12 can be automatically controlled. However, it is not essential to provide the control unit 70 and the detection unit 60, and the operation control of the second conveyor may be performed manually by the operator.

  A sample plate placed on the second conveyor 12 that is stopped can be collected and checked for quality. According to the sample collection device 100, it is possible to sufficiently suppress the occurrence of wrinkles and breakage of the sample plate to be collected. That is, according to the sample collection device 100, a sample plate having excellent quality can be collected while simplifying the device configuration. When scrap pieces are included in a plurality of sample plates, after removing the sample plates whose quality is to be checked, the second conveyor 12 can be operated to collect the scrap pieces in the container 40. Since the container 40 is disposed on the floor, the scrap piece can be taken out and the container 40 can be easily replaced.

  FIG. 2 is a flowchart of a sample collection method according to an embodiment. In the sample collection method of the present embodiment, the conveying step S1 for conveying the steel plate, the sample plate and the scrap piece on the first conveyor, and the steel plate and the sample plate are respectively conveyed to the reel and the second conveyor on the downstream side of the first conveyor. As described above, the sorting step S2 for sorting the steel plate and the sample plate, the sample placing step S3 for placing the sample plate on the second conveyor, and the sample plate placed on the second conveyor after being transferred by the second conveyor Scrapping step S4 for stopping the second conveyor in the state, sampling step S5 for collecting the sample plate from the second conveyor, and operating the second conveyor to put the scrap pieces in the container provided on the downstream side of the second conveyor Recovery step S6 for recovering.

  Each above-mentioned process can be performed using the sample collection device 100 shown in FIG. A sample collection method when the sample collection device 100 is used will be described below along with details of the sample collection device 100.

  The steel plate 50 that has been surface-treated with a continuous surface treatment facility or the like passes between the pair of pinch rolls 20 and is introduced into the sample collection device 100. The first conveyors 11a, 11b, and 11c in the sample collection device 100 are magnet conveyors including electromagnets that can be excited and reverse-excited. The first conveyors 11a, 11b, and 11c convey the steel plate 50 toward the deflector roll 14a while adsorbing the steel plate 50 with magnetic force.

  The traveling direction of the steel plates 50 conveyed by the first conveyors 11a, 11b, and 11c is changed toward the reel 30 by the deflector roll 14a. The deflector roll 14a includes an electromagnet capable of excitation and reverse excitation. By the action of the electromagnet provided in the deflector roll 14 a, the traveling direction of the steel plate 50 can be adjusted toward the reel 30.

  When the type of the steel plate 50 supplied from the pinch roll 20 of the sample collecting device 100 is switched, the traveling steel plate 50 is cut by the drum shear 22 on the upstream side of the first conveyors 11a, 11b, 11c, and has a predetermined length. A plurality of sample plates are obtained. The plurality of sample plates follow the steel plate 50 and circulate in the sample collection device 100.

  As shown in FIG. 3, the several sample plate 52 obtained by cut | disconnecting the steel plate 50 is conveyed by the 1st conveyors 11a, 11b, and 11c. There is no restriction | limiting in particular in the number of the sample plates 52 conveyed. The sample plate 52 may include scrap pieces 54 that are not used for the quality check of the steel plate 50. The first conveyors 11a, 11b, and 11c convey the steel plate 50 wound around the reel 30 and a plurality of sample plates 52 including scrap pieces 54 in some cases (conveying step S1). As with the steel plate 50, the first conveyors 11a, 11b, and 11c convey the plurality of sample plates 52 toward the deflector roll 14a while adsorbing them with magnetic force.

  FIG. 3 shows a state in which a plurality of sample plates 52 are sequentially conveyed by the first conveyors 11a, 11b, and 11c, and the leading sample plate 52 reaches the deflector roll 14a. As shown in FIG. 3, the rear end of the steel plate 50 that precedes the sample plate 52 is adjusted by the deflector roll 14 a so that the traveling direction is directed toward the reel 30, and is wound by the reel 30. After the rear end of the steel plate 50 passes through the deflector roll 14a, the transport destination of the sample plate 52 behind the steel plate 50 and the steel plate 50 is sorted by changing the direction of the magnetic field of the deflector roll 14a (sorting step S2).

  In this way, the steel plate 50 is transported to the reel 30 and the sample plate 52 is transported to the second conveyor 12. The second conveyor 12 does not convey the steel plate 50. That is, the deflector roll 14a has a function of distributing the transport destinations of the steel plate 50 and the sample plate 52 to the reel 30 and the second conveyor 12, respectively. The direction of the magnetic field of the deflector roll 14a can be changed by switching between excitation and reverse excitation. The deflector roll 14a may be referred to as a direction changing roll or a turn-down roll.

  The sample collection device 100 includes a third conveyor 13 above the second conveyor 12 and the deflector roll 14a. The 3rd conveyor 13 is also a magnet conveyor provided with an electromagnet inside, and the direction of the magnetic field can be changed by switching between excitation and reverse excitation of the electromagnet. The steel plate 50 is adjusted by the deflector roll 14a so that it travels toward the reel 30 without being attracted to the third conveyor 13.

  After the rear end of the steel plate 50 passes through the deflector roll 14a, the sample plate 52 behind the steel plate 50 is changed to the third conveyor 13 by changing the direction of the magnetic field of the third conveyor 13 together with the direction of the magnetic field of the deflector roll 14a. It is adsorbed on the lower surface. The sample plate 52 adsorbed on the lower surface of the third conveyor 13 is conveyed to the second conveyor 12. The sample plate 52 that has reached the upper side of the second conveyor 12 falls from the third conveyor 13 and is placed on the second conveyor 12 (sample placement step S3).

  The conveyance speed Vs of the sample plate 52 in the first conveyors 11a, 11b, 11c and the deflector roll 14a may be higher than the conveyance speed Vp of the steel sheet 50 wound around the reel 30 (Vs> Vp). In this case, as shown in FIG. 3, the interval between the sample plates 52 adjacent to each other in the front-rear direction and the interval between the last sample plate 52 and the steel plate 50 following the sample plate 52 can be increased. Thereby, the sample plate 52 and the steel plate 50 can be more reliably distributed in the deflector roll 14a. The ratio (Vs / Vp) of the conveyance speed Vs to the conveyance speed Vp is, for example, 1.1 to 1.5, and preferably 1.15 to 1.3.

  The plurality of sample plates 52 that have been sequentially distributed through the first conveyors 11a, 11b, and 11c are sequentially conveyed to the second conveyor 12 by the deflector roll 14a and the third conveyor 13. The conveyance speed V3 of the sample plate 52 in the third conveyor 13 may be the same as the conveyance speed Vs of the sample plate 52 in the first conveyors 11a, 11b, and 11c. The sample plates 52 conveyed by the third conveyor 13 are sequentially placed on the operating second conveyor 12.

  FIG. 4 is a diagram illustrating a state in which a plurality of sample plates 52 are placed on the second conveyor 12. The conveyance speed V2 of the sample plate 52 in the second conveyor 12 is slower than the conveyance speed Vs of the sample plate 52 in the first conveyors 11a, 11b, and 11c and the conveyance speed V3 of the sample plate 52 in the third conveyor 13 ( V2 <Vs = V3). As a result, the plurality of sample plates 52 transported by the first conveyors 11a, 11b, 11c and the third conveyor 13 adjacent to each other in the front-rear direction are stacked on the second conveyor 12 so as to be continuous in the front-rear direction. Placed.

  The plurality of sample plates 52 are placed such that the front end portion of the sample plate 52 following the sample plate 52 overlaps the rear end portion of the sample plate 52 already placed on the second conveyor 12 from above. Is done. Thus, the length of the 2nd conveyor 12 can be shortened by mounting the some sample board 52 so that it may continue in a row and may overlap up and down. Thereby, the length of the 2nd conveyor 12 can be shortened and the installation space of the sample collection apparatus 100 can be made small.

  The ratio (V2 / Vp) of the conveyance speed V2 of the sample plate 52 in the second conveyor 12 to the conveyance speed Vp of the steel plate 50 is, for example, 0.5 to 0.9. The ratio is preferably 0.6 to 0.8 from the viewpoint of sufficiently improving the ease of collection of the sample plate 52 while reliably maintaining the overlap between the sample plates 52. Note that it is not essential that the sample plates 52 overlap each other on the second conveyor 12, for example, Vs = V2 = V3> Vp, and a plurality of sample plates 52 are predetermined along the horizontal direction without overlapping vertically. They may be placed side by side at intervals.

  When a predetermined number of sample plates 52 obtained by cutting with the drum shear 22 are placed on the second conveyor 12, the conveyance of the second conveyor 12 is stopped (stopping step S4). The conveyance of the second conveyor 12 may be stopped by automatic control or manually. The sample collection device 100 includes a detection unit 60 that detects the sample plate 52, and a control unit 70 that stops the second conveyor 12 with the sample plate 52 placed on the basis of a signal from the detection unit 60.

  The control unit 70 is configured to count the number of sample plates 52. When the detection unit 60 detects the same number of sample plates 52 as the number of sample plates 52 cut by the drum shear 22, the control unit 70 outputs a control signal for stopping the second conveyor 12. Thereby, the 2nd conveyor 12 stops. In addition, the detection part 60 and the control part 70 may be comprised integrally by hardware, and may be comprised separately. In some other embodiments, the operator confirms the number of sample plates 52 detected by the detection unit 60 on a monitor provided in the detection unit 60, and the operator manually moves the second conveyor 12 according to the result. You may stop.

  If the 2nd conveyor 12 stops, the sample board 52 used for the quality check of the steel plate 50 will be extract | collected out of the several sample board 52 mounted on the 2nd conveyor 12 (sampling process S5). The method of collecting the sample plate 52 is not particularly limited, and for example, the operator may grasp the sample plate 52 and collect it.

  While performing the above-mentioned sampling process S5, the 1st conveyor 11b conveys the steel plate 50 wound around the reel 32 following the last sample board 52 (conveyance process S1). The traveling direction of the steel plate 50 is adjusted so as to be directed to the reel 32 by a deflector roll 14b provided between the first conveyor 11a and the first conveyor 11b. Similarly to the deflector roll 14a, the deflector roll 14b also includes an electromagnet. The direction of the magnetic field of the deflector roll 14b can be changed by switching between excitation and reverse excitation of the electromagnet. After the rear end of the last sample plate 52 passes through the deflector roll 14b, the traveling direction of the steel plate 50 behind the last sample plate 52 is directed toward the reel 32 by changing the direction of the magnetic field of the deflector roll 14b. (Sorting process S2).

  Thus, the steel plate 50 is continuously wound around the reel 32 while the sample plate 52 on the second conveyor 12 is being collected. When the steel sheet type changes again, the steel plate 50 is cut by the drum shear 22 to obtain a plurality of sample plates 52. The sample plate 52 is conveyed by the deflector roll 14b toward the second conveyor 12 via the first conveyor 11a and the deflector roll 14a. Then, the sample plate 52 is placed on the second conveyor 12 via the third conveyor 13. Thus, since the sample collection device 100 includes the two reels 30 and 32, the series of steps can be performed not only continuously but also in parallel. For this reason, sample collection of the sample plate 52 can be performed efficiently.

  The plurality of sample plates 52 includes scrap pieces (crop) 54. Since the scrap piece 54 is not used for the quality check of the steel plate 50, it remains on the second conveyor 12 without being collected in the sampling step S5. Therefore, after the sampling step S5, as shown in FIG. 5, the second conveyor 12 is operated, and the scrap pieces 54 are collected in the scrap piece 54 collection container 40 provided on the downstream side of the second conveyor 12. (Recovery step S6). Thus, by collecting the scrap pieces 54 after collecting the sample plates 52 used for the quality check, the sample plates 52 and scrap pieces 54 used for the quality check can be reliably and easily separated.

  In the sample collection device 100 and the sample collection method using the same, the sample plate 52 can be collected on the second conveyor 12. Therefore, compared with the case where the sample plate 52 is collected in a box-shaped container, generation of wrinkles and folds in the sample plate 52 can be sufficiently suppressed. In addition, since it is not essential to provide a chute for decelerating the sample plate and a shear exclusively for removal, it is possible to simplify the apparatus configuration and reduce the installation space of the apparatus. However, it goes without saying that the sample collection device 100 may have any configuration other than the above-described configuration.

  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. For example, the sampling of the sample plate 52 is not necessarily coincident with the switching timing of the steel plate type, and the sample plate is switched at the timing when the reels 30 and 32 are switched after the steel plate 50 is wound around the reels 30 and 32 a predetermined number of times. 52 may be collected. The provision of the third conveyor 13 is not essential, and the sample plates 52 may be arranged side by side along the horizontal direction on the second conveyor 12. The scrap piece 54 may be collected by the operator without providing the container 40 for collecting the scrap piece 54. The number of reels is not limited to two and may be three or more. At this time, a deflector roll is provided on the upstream side of each reel, and the transport destination of the steel plate and the sample plate is distributed by the deflector roll. Note that the sample plate 52 may not include the scrap piece 54, and in that case, the collection step S6 may not be performed.

  Provided are a sample collection device and a sample collection method that can simplify the configuration of the device and sufficiently suppress the occurrence of wrinkles and creases in the sample plate.
