Sampling equipment, plate manufacturing equipment, gypsum-based building material manufacturing equipment
[0001] The present invention relates to a sampling device, a plate member manufacturing device, and a gypsum-based building material manufacturing device.
[0002] Patent document 1 discloses a sampling device having a pushing-up means for pushing up a plate piece being transported by a transporting means from below the transport path of the plate piece to above the transport path, and a holding means for holding the plate piece pushed up by the pushing-up means.
[0003] International Publication No. 2018 / 193942
[0004] Plate-shaped products containing inorganic materials such as ceramics and metals, or organic or polymeric materials such as resins as raw materials are continuously produced, for example, by forming the raw materials into a continuous strip, and then transporting the formed product while performing various operations such as cutting and drying as necessary.
[0005] Then, at any timing or a predetermined timing, an operator, for example, samples the semi-finished products or parts of the products being conveyed to evaluate whether the semi-finished products, etc. are being manufactured in accordance with the standards. Since the semi-finished products, etc. are usually conveyed continuously, depending on the conveying speed, size, weight, etc. of the semi-finished products, it may require skilled techniques for the operator to manually sample the semi-finished products, etc.
[0006] Therefore, the applicant invented the sampling device disclosed in Patent Document 1.
[0007] However, the sampling device disclosed in Patent Document 1 requires at least two components: a push-up means and a holding means, which requires a large installation space and can be difficult to install depending on the length of the production line.
[0008] In view of the above-mentioned problems of the conventional technology, one aspect of the present invention aims to provide a sampling device that can easily sample plate pieces being transported and that can reduce installation space.
[0009] In order to solve the above problem, according to one form of the present invention, there is provided a sampling device comprising: a support device that supports a plate piece being transported by a transport device from below the plate piece; and a displacement device that displaces the position of the support device along a height, wherein the support device comprises: a connecting member having a columnar shape; a plurality of support members also having a columnar shape arranged along the longitudinal direction of the connecting member; and a counterweight installed on the connecting member, wherein the support members are arranged so that the longitudinal direction of the connecting member and the longitudinal direction of the support members intersect, and of a first end along the longitudinal direction of the support member and a second end located opposite the first end, the first end is fixed to the connecting member, and the counterweight is located on the opposite side of the side where the second end of the support member is located, based on the position of the connecting member.
[0010] According to one aspect of the present invention, it is possible to provide a sampling device that can easily sample plate pieces being transported and that can reduce installation space.

[0012] Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. However, the present invention is not limited to the following embodiments, and various modifications and substitutions can be made to the following embodiments without departing from the scope of the present invention.
[0013] In this specification, the names of components may be described with a designation such as "first," "second," etc. added to them. In this specification, for example, they are described as "first moving device," "second moving device," etc. The designations "first" and "second" added to the names of components are merely used to distinguish between the components and to prevent confusion during description, and do not represent placement or priority. When there is no risk of confusion or when referring collectively, they can simply be referred to as moving devices. [Sampling Device] An example configuration of the sampling device of this embodiment will be described.
[0014] Fig. 1 shows a perspective view of the sampling device 10 of this embodiment. The conveying device 21 is not shown in Fig. 1. Fig. 2 shows a top view of the sampling device 10 of this embodiment installed on a conveying path 26 for plate pieces 25. Figs. 3 and 4 show side views as viewed along the block arrow 20 in Fig. 2. Fig. 3 shows the state before the position of the support device 11 is raised by the displacement device 12, and Fig. 4 shows the state after the position of the support device 11 has been raised by the displacement device 12.
[0015] 1 to 4, the X axis is the axis along the transport path 26 of the plate piece 25, the Y axis is the axis along the width of the plate piece 25, and the Z axis is the axis along the height.
[0016] As shown in FIG. 1 , the sampling device 10 of this embodiment includes a support device 11 that supports the plate piece 25 being transported by a transport device 21 (see FIG. 2 ) from below the plate piece 25, and a displacement device 12 that vertically displaces the position of the support device 11. (1) Transport Device, Plate Piece First, we will explain the plate piece 25 sampled by the sampling device 10 of this embodiment and the transport device 21 that installs the sampling device 10 and transports the plate piece 25. (Transport Device) As shown in FIGS. 2 to 4 , the transport device 21 is not particularly limited as long as it can transport the plate piece 25, i.e., a plate-shaped semi-finished product or finished product, and can accommodate the support device 11. However, it is preferable that the transport device 21 be a device that can transport the plate piece 25 horizontally. Although not particularly limited, the transport device 21 is preferably a device that does not interfere with the support member 111 and the movable parts of the transport device 21, specifically, the parts that are driven to transport the plate piece 25, when the position of the support device 11 is displaced by the displacement device 12. As the conveying device 21, for example, a roll conveyor or a chain conveyor can be preferably used, and as the conveying device 21, a roll conveyor can be more preferably used.
[0017] The chain conveyor means a conveyor in which at least two rows of chains are wound between a plurality of rolls, and the chains are rotated by rotating the rolls, thereby transporting plate pieces by the chains.
[0018] 2 to 4, the roll conveyor is a conveyor in which a plurality of rolls 211 to 220 are arranged, the rolls 211 to 220 support the plate pieces 25, and the rolls 211 to 220 are rotated to transport the plate pieces 25. Due to paper width limitations, the numbers of the rolls are only given in FIG. 2.
[0019] The configuration of the conveying device 21 may be different between the portion where the support device 11 is installed and the other portion. For example, the conveying device 21 may be a roll conveyor only in the portion where the support device 11 is installed, and the conveying devices 21 before and after that may be belt conveyors.
[0020] The sampling device 10 of this embodiment can be configured without the transport device 21 and only include the support device 11, displacement device 12, etc., which will be described below, or the sampling device can also include the transport device 21. (Plate Piece) The plate piece 25 is not particularly limited as long as it is plate-shaped. Examples include plate-shaped semi-finished products and finished products containing inorganic materials such as ceramics and metals, or organic or polymeric materials such as resins as raw materials, and more specifically, examples include gypsum-based building materials, which will be described later.
[0021] There are no particular limitations on the size of the plate pieces 25. The plate pieces 25 used for sampling and the other plate pieces 25 may be the same size or different sizes.
[0022] The width and length of the plate pieces 25 can be determined appropriately depending on the type and physical properties of the semi-finished or finished product. For example, in the case of building materials, the width is preferably 450 mm to 1600 mm, and the length is more preferably 3500 mm to 22500 mm. There are no particular restrictions on the thickness of the plate pieces 25, but if they are too thin or too thick, they may be difficult to transport using the transport device 21, so it is preferable that they be, for example, 1 mm to 50 mm.
[0023] In addition, when the size of only the plate piece 25 to be sampled is changed from that of the other plate pieces not to be sampled as described above, for example, only the length can be set to 1 / 30 to 4 / 5 of that of the plate pieces not to be sampled. In this case, the size of the plate pieces not to be sampled can be set within the range described above, for example.
[0024] The plate pieces 25 are transported by the transport device 21, and the area surrounded by the bottom surface, top surface, and both widthwise ends of the transported plate pieces 25 forms the transport path 26. Of the transport path 26, the surface formed by the bottom surface of the transported plate piece 25, i.e., the surface that contacts the transport device 21, is also referred to as the bottom surface 26A of the transport path 26. The surface formed by the top surface of the transported plate piece 25 is also referred to as the top surface 26B of the transport path 26 (see Figures 3 and 4). (2) Support Device The support device 11 has a columnar connecting member 112, a plurality of columnar support members 111 arranged along the longitudinal direction of the connecting member 112, i.e., the X-axis, and a counterweight 113 installed on the connecting member 112.
[0025] The components of the support device 11 will now be described. (2-1) Support Member The support member 111 is a member that directly supports the plate piece 25 from below the plate piece 25, and can have a columnar shape. Note that a columnar shape can also be referred to as a rod-like shape. In this specification, the term columnar shape does not have a strict geometrical meaning, and for example, the surface can have irregularities or the like for connecting to the connecting member 112.
[0026] The support member 111 may have a polygonal prism shape such as a quadrangular prism shape, or a cylindrical shape. The support device 11 may have a plurality of support members 111, but all of the support members 111 do not need to have the same shape, and the shape of the support members 111 may be changed depending on the placement location, etc. For example, in order to prevent scratches, etc. on the plate pieces 25 to be sampled, the support member 1111 of the plurality of support members 111 arranged upstream in the conveying direction of the plate pieces 25 may be cylindrical (round bar).
[0027] The material of the support member 111 is not particularly limited, and one or more types selected from, for example, resin, metal, etc. can be used. However, depending on the mass of the plate piece 25, etc., it is preferable that the support member 111 has high rigidity so that it can support the plate piece 25. Therefore, depending on the mass of the plate piece 25, etc., the support member 111 can be made of metal, such as stainless steel or aluminum. The support member 111 can also be hollow, etc., so as to prevent excessive load from being applied to the displacement device 12.
[0028] The support device 11 can have multiple support members 111, which can be arranged along the longitudinal direction of the connecting member 112. In the support device 11 shown in FIG. 1 , five support members 111 are arranged along the longitudinal direction of the connecting member 112, but the present invention is not limited to this configuration, and the number of support members 111 can be selected depending on the size, weight, etc. of the plate piece 25 to be sampled. The distance between the arranged support members 111 is not particularly limited and may be constant, for example. Furthermore, the distance between the support members 111 may be configured to vary depending on the location, for example, by shortening the distance between the support members 111 so that the support members 111 can be arranged at a higher density in areas where a high load is applied when the plate piece 25 is placed.
[0029] The support member 111 has a first end 111A along its length and a second end 111B located opposite the first end 111A. Of the first end 111A and the second end 111B, the support member 111 has the first end 111A fixed to the connecting member 112. The second end 111B is not particularly limited, but may be a free end that is not fixed to another member, as shown in Figures 1 and 2.
[0030] The support member 111 can be arranged so that the longitudinal direction of the connecting member 112 and the longitudinal direction of the support member 111 intersect, and is preferably arranged so that the longitudinal direction of the connecting member 112 and the longitudinal direction of the support member 111 are perpendicular to each other. Note that "perpendicular" does not have a strict geometrical meaning, but may be within a range that can be regarded as perpendicular, and for example, an angle between the longitudinal direction of the support member 111 and the longitudinal direction of the connecting member 112 that is between 80 degrees and 100 degrees can be regarded as perpendicular.
[0031] Furthermore, the position of the support device 11 can be changed so that when the support device 11 is at its lowest position, the support members 111 can be accommodated between the rolls of the conveying device 21. For this reason, it is preferable that the support members 111 are arranged in parallel to one another so that the support members 111 do not interfere with the rolls of the conveying device 21.
[0032] 1, 3, and 4, the multiple support members 111 are arranged to be at the same height, but this is not a limitation. For example, the multiple support members 111 may be arranged so that the support member 1112 located downstream of the conveyance path 26 of the plate piece 25 is higher than the support member 1111 located upstream of the conveyance path 26 of the plate piece 25, and fixed to the connecting member 112.
[0033] That is, the support members 111 may be arranged so that the surface on which the plate pieces 25 are placed, formed by the support members 111, is an inclined surface, and the support members 111 are arranged so that the downstream side is higher along the conveyance path 26 of the plate pieces 25. By arranging the support members 111 so that the downstream side is higher along the conveyance path 26 of the plate pieces 25, an inclined surface can be formed on the placement surface formed by the support members 111 when the plate pieces 25 are sampled. Therefore, when the plate pieces 25 are sampled using the sampling device 10 of this embodiment, the plate pieces 25 being transported by the transport device 21 can be prevented from shifting from above the support members 111 due to inertia. Therefore, the sampling device 10 of this embodiment can more reliably sample the plate pieces 25.
[0034] The support members 111 may also have friction members 15 on at least a portion of the portion that contacts the plate pieces 25. By providing the friction members 15, when the plate pieces 25 are sampled by the sampling device 10 of this embodiment, the plate pieces 25 being transported by the transport device 21 can be prevented from shifting from above the multiple support members 111 due to inertia. Therefore, the sampling device 10 of this embodiment can more reliably sample the plate pieces 25.
[0035] The friction member 15 is not particularly limited, and any material can be used as long as it increases the friction between the surface of the support member 111 and the plate piece 25 compared to when the friction member 15 is not provided. Examples include rubber and fine powder. It is preferable to select the material of the friction member 15 according to the material of the plate piece 25 so as not to scratch the surface of the sampled plate piece 25. (2-2) Connecting Member The connecting member 112 is a member for connecting and supporting the support member 111 and the counterweight 113, and can have a columnar shape as shown in FIG. 1. Note that a columnar shape can also be referred to as a rod shape. As with the support member 111, the columnar shape of the connecting member 112 does not have a strict geometrical meaning and can have irregularities for connection to other components, etc.
[0036] The connecting member 112 may have a polygonal prism shape such as a quadrangular prism shape, or a cylindrical shape.
[0037] The material of the connecting member 112 is not particularly limited, and one or more types selected from, for example, resin, metal, etc. can be used. However, depending on the mass of the plate piece 25, etc., it is preferable that the connecting member 112 has high rigidity so as to be able to support the plate piece 25. Therefore, depending on the mass of the plate piece 25, etc., the connecting member 112 can be made of metal, stainless steel, aluminum, etc. The connecting member 112 can also be hollow inside so as to prevent excessive load from being applied to the displacement device 12.
[0038] By displacing the position of the connecting member 112 with the displacement device 12, the positions of the support member 111 and the counterweight 113 attached to the connecting member 112 can also be displaced. (2-3) Counterweight The inventors of the present invention have studied a sampling device in which the plate piece 25 is supported by a support device 11 consisting of a support member 111 and a connecting member 112, the position of the support device 11 is displaced along the height with the displacement device 12, and the plate piece 25 is held by the support device 11. With this sampling device, there is no need to provide a separate means for holding the sampled plate piece 25, and therefore the installation space for the sampling device can be reduced.
[0039] However, when the support device 11 supports the plate piece 25 and the position of the support device 11 is displaced by the displacement device 12, over time the support device 11 tilts toward the support member 111 holding the plate piece 25, applying a load to the drive portion of the displacement device 12. Furthermore, depending on the angle of tilt, the position of the plate piece 25 on the support member 111 may be displaced, or the support member 111 may interfere with the transport path of the plate piece 25.
[0040] Therefore, the support device 11 can further include a counterweight 113 .
[0041] The counterweight 113 can be disposed on the opposite side of the second end 111B of the support member 111 with respect to the position of the connecting member 112. That is, when viewed along the Y axis in Figures 1 to 4, the second end 111B of the support member 111 and the counterweight 113 are disposed at opposite positions with respect to the connecting member 112.
[0042] By providing the counterweight 113, it is possible to balance the load between the support member 111, the plate piece 25 arranged on the support member 111, and the counterweight 113. This prevents the support device 11 from tilting toward the support member 111, and prevents a load from being applied to the displacement device 12, the position of the plate piece 25 on the support member 111 from being displaced, and the support member 111 from interfering with the conveyance path 26 of the plate piece 25.
[0043] The number of counterweights 113 to be installed is not particularly limited and may be one, but the support device 11 may also have multiple counterweights 113 along the longitudinal direction of the connecting member 112.
[0044] Since the support device 11 has multiple counterweights 113 along the length of the connecting member 112, it becomes easier to balance the support member 111 and the plate piece 25 placed on the support member 111 over the entire range in which the support member 111 is installed.
[0045] The configuration of the counterweight 113 is not particularly limited. For example, it may be a fixed type in which the position of the weight does not change, or a movable type in which the position of the weight is displaced. That is, as shown in FIGS. 1 and 2 , the counterweight 113 may have a first moving device 1131 that changes the distance from the connecting member 112, or the position of the weight may be movable. The first moving device 1131 is a device that moves the position of the weight of the counterweight 113 and changes the distance from the connecting member 112 to the weight. By including the first moving device 1131 in the counterweight 113, it is possible to control the balance of the counterweight 113 with the support member 111 and the plate piece 25 placed on the support member with high precision. The first moving device 1131 may be a device that manually moves the position of the weight, or a device that automatically moves the position of the weight using an actuator or the like.
[0046] When the first moving device 1131 is configured as a device that automatically moves the position of the weight, the configuration of the first moving device 1131 is not particularly limited. The first moving device 1131 may be configured, for example, by combining a linear motion mechanism such as a linear rail (linear guide), a linear shaft, or a linear bushing with a driving device such as a linear motor or a motor. In addition, the counterweight 113 may have a control device that automatically moves the position of the weight and controls the inclination based on, for example, the inclination of the support device 11. (3) Displacement Device The displacement device 12 can displace the position of the support device 11 along the height, i.e., along the Z axis.
[0047] The location of the displacement device 12 is not particularly limited, and for example, the displacement device 12 can be connected to any location on the support device 11 so as to be able to displace the position of the support device 11. The displacement device 12 can be connected to the connecting member 112, for example, and can be located below the connecting member 112.
[0048] The displacement device 12 is connected to the connecting member 112, and by displacing the position of the connecting member 112, the positions of the support member 111 and the counterweight 113 installed on the connecting member 112 can also be displaced.
[0049] 3, before sampling, the displacement device 12 can position the support member 111 of the support device 11 below the lower surface 26A of the conveying path 26 of the plate piece 25. At this time, the support member 111 of the support device 11 can be positioned so as not to interfere with the movable parts of the conveying device 21. If the conveying device 21 is a roll conveyor, the support member 111 can be positioned between the rolls 211 to 220 of the roll conveyor so as to be parallel to the rolls.
[0050] When sampling is performed, the displacement device 12 can push up the support device 11 and move the support member 111 above the upper surface 26B of the transport path 26. It is preferable that the displacement device 12 adjusts and selects the position of the support device 11 so that the following plate piece does not interfere with the support device 11.
[0051] After the sampled plate piece 25 is discharged to the outside by the discharge device 13 or the like, the displacement device 12 displaces the support member 111 of the support device 11 below the lower surface 26A of the conveying path 26 of the plate piece 25, thereby preparing for the next sampling.
[0052] The configuration of the displacement device 12 is not particularly limited, but may include one or more types selected from, for example, an electric actuator, a hydraulic cylinder, a pneumatic (air-pressure) cylinder, etc. In particular, a pneumatic cylinder is preferred because a high lifting speed is desirable for sampling the plate piece 25 being transported.
[0053] 3 and 4 , the displacement device 12 preferably displaces the support device 11 perpendicular to the conveying path 26 of the plate pieces 25. By displacing the support device 11 perpendicular to the conveying path 26 with the displacement device 12, it is possible to particularly reduce the installation space required for installing the sampling device 10 including the support device 11 and the displacement device 12.
[0054] The displacement device 12 displacing the support device 11 perpendicular to the conveyance path 26 of the plate piece 25 means displacing the support device 11 perpendicular to the upper surface 26B or the lower surface 26A of the conveyance path 26. "Perpendicular" does not have a strict geometrical meaning, but includes a range that can be considered perpendicular taking into account the accuracy of the displacement device 12, etc. Therefore, for example, an angle between the upper surface 26B or the lower surface 26A of the conveyance path 26 and the support device 11 that is 80 degrees or more and 100 degrees or less can be considered perpendicular. The angle is preferably 85 degrees or more and 95 degrees or less.
[0055] There is no particular limitation on the timing at which the displacement device 12 pushes up the support device 11. For example, the displacement device 12 may be configured to push up the support device 11 after an operator visually confirms that the plate piece 25 is positioned on the support member 111.
[0056] The displacement device 12 may also be configured to automatically push up the support device 11 in accordance with a predetermined timing, etc. For example, the displacement device 12 may be configured to push up the support device 11 after a predetermined time has elapsed after the cutting device 23, which will be described later, has operated. The displacement device 12 may also be configured to push up the support device 11 after detecting, by various sensors or the like, that the plate piece 25 is positioned on the support member 111. (4) Discharge Device The plate piece 25 sampled by the sampling device 10 of this embodiment and placed on the support member 111 can also be sampled manually by an operator.
[0057] The sampling device 10 may further include a discharge device 13 that supports the sampled plate piece 25 by a support device 11 and moves the sampled plate piece 25 together with the support device 11 upward on the conveying path 26 of the plate piece 25 by a displacement device 12, thereby discharging the sampled plate piece 25 from the support device 11.
[0058] The configuration of the discharge device 13 is not particularly limited. For example, the discharge device 13 may have a plurality of discharge members 132 and a fixed member 131 to which the plurality of discharge members 132 are fixed. The discharge device 13 may also have a second moving device 133 that moves the fixed member 131 along the double-headed arrow A (see FIG. 1 ). The second moving device 133 is a device that moves the fixed member 131 and the discharge member 132.
[0059] The second moving device 133 moves the ejection member 132 via the fixed member 131 and brings it into contact with the plate piece 25, thereby moving the plate piece 25 along the Y axis, for example, and ejecting the plate piece 25 from the support device 11. Note that a transport device for the sampled plate piece 25 may be disposed in the ejection direction, and the ejected plate piece 25 may be further transported to a desired location.
[0060] The configuration of the second moving device 133 is not particularly limited, and can be a combination of a linear motion mechanism such as a linear rail (linear guide), a linear shaft, or a linear bushing, and a driving device such as a linear motor or a motor.
[0061] As shown in FIGS. 3 and 4, the discharge device 13 is preferably provided at a position where it does not interfere with the plate pieces 25 and the like being transported along the transport path 26 by the transport device 21.
[0062] The configuration of the discharge device 13 is not limited to the above configuration, and may be configured, for example, such that a roll or the like is provided on the surface of the support member 111 facing the plate pieces 25, so that the plate pieces 25 can be transported and discharged along the length of the support member 111. (5) Stopper The sampling device 10 of this embodiment may further have a stopper 14 downstream of the multiple support members 111 along the transport path 26 for the plate pieces 25.
[0063] The stopper 14 is a member that restricts the movement of the plate piece 25 sampled on the support member 111 .
[0064] The sampling device 10 has the stopper 14, which prevents the plate pieces 25 being transported by the transport device 21 from protruding above the support members 111 due to inertia when the plate pieces 25 are sampled by the sampling device 10 of this embodiment. Therefore, the sampling device 10 of this embodiment can more reliably sample the plate pieces 25.
[0065] The configuration of the stopper 14 is not particularly limited, but it may have a restricting member 141 that comes into direct or indirect contact with the plate piece 25 sampled on the support member 111 and restricts movement of the plate piece 25. The configuration of the restricting member 141 is not particularly limited as long as it is configured to restrict movement of the sampled plate piece 25, and it may have, for example, a plate-shaped member as shown in Fig. 1 or one or more columnar-shaped members.
[0066] The stopper 14 may also have an elastic member 142 on the surface of the regulating member 141 that faces the plate piece 25. The elastic member 142 may be made of a material that can absorb impact, such as various types of rubber or sponge.
[0067] The stopper 14 has the elastic member 142 , so that even if the plate piece 25 comes into contact with the restricting member 141 of the stopper 14 , the plate piece 25 can be prevented from being damaged.
[0068] The stopper 14 is preferably used when sampling a plate piece 25 that easily slides on the support member 111, and is preferably not used when a non-slip plate piece 25 can be easily sampled on the support member 111. This is to prevent the sampled plate piece 25 from being damaged.
[0069] For this reason, the stopper 14 may also have a rotation device 143 so that, when the stopper 14 is not in use, the regulating member 141 can be rotated, for example, along the double-headed arrow B in FIG. 1 to put the regulating member 141 out of contact with the plate piece 25. The rotation device 143 is a device for rotating the regulating member 141 and the elastic member 142. When the plate piece 25 on the support member 111 moves to the position of the stopper 14, the rotation device 143 can be configured to switch between a state in which the plate piece 25 and the regulating member 141 are in contact with each other and a state in which they are not in contact with each other.
[0070] A device capable of rotating the regulating member 141 by a predetermined angle, such as a rotary actuator, can be used as the rotating device 143. When the stopper 14 has the elastic member 142, it is preferable that the rotating device 143 be configured so that the elastic member 142 can rotate together with the regulating member 141.
[0071] The power source of the rotation device 143 is not particularly limited, and any rotary actuator powered by a selected type, such as an electric or pneumatic (air) type, can be used. If a pneumatic rotary actuator is used as the rotation device 143, when the plate piece 25 comes into direct or indirect contact with the regulating member 141, the air in the rotary actuator absorbs the impact, allowing the rotation device 143 to exhibit a shock absorbing function. For this reason, a pneumatic rotary actuator is preferably used as the rotation device 143. (6) Stand The support device 11, the displacement device 12, the ejection device 13, and the stopper 14 may each be separate, independent devices that are not connected to each other, or may be configured to be connected to a stand 31, as shown in Figures 3 and 4, for example.
[0072] The support device 11, displacement device 12, discharge device 13, and stopper 14 are integrated into the stand 31, which makes it easy to install the support device 11 on the transport device 21, etc., and to adjust the positioning. The stand 31 can also be provided with a moving device for the stand, such as casters, as needed. (7) Cutting Device, Upstream Transport Device The sampling device 10 of this embodiment can also have a cutting device 23 and an upstream transport device 22 upstream of the transport device 21 already described.
[0073] The sampling device 10 of this embodiment may further include a cutting device 23 that cuts the plate 24 into plate pieces 25, and an upstream conveying device 22 that conveys the plate 24 and supplies it to the cutting device 23. In this case, the conveying device 21 may be disposed downstream of the cutting device 23 along a conveying path 26 of the plate pieces 25. When the previously described conveying device 21 is to be particularly distinguished from the upstream conveying device 22, the previously described conveying device 21 may also be referred to as a downstream conveying device.
[0074] The plate 24 is, for example, a strip-shaped semi-finished product or finished product obtained by shaping a raw material, and is a pre-cut transport object before being cut into the plate pieces 25. By cutting the plate 24, a portion of the plate 24 can be separated as the plate piece 25. Furthermore, by cutting the plate 24 multiple times, multiple plate pieces 25 can be formed.
[0075] The shape of the cutting line when cutting the plate body 24 is not particularly limited, but may be, for example, a cutting line parallel to the width of the plate body 24, i.e., a cutting line perpendicular to the conveying direction of the plate body 24. Therefore, the plate body 24 may have a shape that is longer in the conveying direction than the plate pieces 25 after cutting, such as a strip shape as described above.
[0076] The configuration of the cutting device 23 is not particularly limited, but for example, a cutting device that can cut the conveyed plate body 24 along a cutting line parallel to the width direction of the plate body 24 can be used. Specifically, for example, a rotary cutter, a rotary saw, or the like can be used.
[0077] The cutting line may be, for example, a cutting line parallel to the conveyance direction of the plate body 24 or a cutting line of any shape. Therefore, the cutting device 23 is not limited to the above-described form, and for example, a cutting device that can cut the plate body 24 along a cutting line parallel to the conveyance direction of the plate body 24 or a cutting line of any shape may be used.
[0078] The displacement device 12 can also be configured to operate in conjunction with the cutting device 23. For example, after the cutting device 23 has performed a predetermined number of cuts, the displacement device 12 can be configured to push up the support device 11 after a predetermined time has elapsed, and sampling can be performed.
[0079] The upstream conveying device 22 may also be a means capable of conveying the plate 24 and supplying it to the cutting device 23, and its configuration is not particularly limited. For example, one or more types selected from a roll conveyor, a belt conveyor, a chain conveyor, etc. may be used. The conveying device 21 and the upstream conveying device 22 described above may be the same conveying device or different conveying devices. (8) Separating Device, Speed Reducer When the sampling device 10 of this embodiment has the cutting device 23, the sampling device 10 may further have a separating device 27 that increases the distance between the plate 24 and the plate pieces 25 obtained by cutting with the cutting device 23, or the distance between the plate pieces 25.
[0080] The separating device 27 and a reduction gear device 28 (described later) are shown only in FIG. 2 and are omitted from the other drawings.
[0081] When the cutting device 23 cuts the plate 24 into plate pieces 25, the distance between the successively transported plate pieces 25 obtained by cutting is very small immediately after the cutting device 23. For this reason, depending on the transport speed when the transport device 21 transports the plate pieces 25, when sampling the plate pieces 25 with the support device 11, it may be necessary to increase the movement speed of the support device 11 by the displacement device 12 so as to prevent contact with the succeeding plate pieces 25.
[0082] In contrast to this, by further providing a spacing device 27 that increases the distance between the plate 24 and the plate piece 25, or the distance between the plate pieces 25, it is not necessary to increase the movement speed of the support device 11 excessively, which is preferable because sampling can be performed particularly easily.
[0083] The specific configuration of the spacing device 27 is not particularly limited, but the spacing device 27 may, for example, have a spacing control device that controls the transport speed of the plate pieces 25 by the transport device 21 for at least a portion of the transport device 21.
[0084] 2, the spacing control device provided in the spacing device 27 preferably controls the conveying speed of the plate pieces 25 for at least a portion of the conveying device 21 so that the conveying speed is faster, i.e., accelerated, than in an area upstream of the conveying device 21, for example, an area immediately preceding the conveying device 21. For example, if the conveying device 21 is a roll conveyor, the spacing control device can control the conveying speed of at least some of the rolls 211 and 212 that make up the roll conveyor of the conveying device 21 to accelerate.
[0085] The spacing device 27 can, for example, increase the distance between the plate pieces 25 cut by the cutting device 23. For this reason, it is preferable that the spacing control device controls the conveying speed of the plate pieces 25 by some of the conveying devices 21 controlled by the spacing control device to be faster than the conveying speed of the plate 24 by the upstream conveying device 22 arranged upstream of the cutting device 23.
[0086] By configuring the separation control device in this manner, after the plate piece 25 that has passed through the cutting device 23 is supplied to the conveying device 21, the plate piece 25 that was previously supplied to the conveying device 21 can be conveyed a considerable distance ahead before the next plate piece 25 is supplied to the conveying device 21. Therefore, the distance between the plate piece 25 that has already been conveyed by the conveying device 21 and the plate piece 25 obtained by cutting by the cutting device 23 can be sufficiently increased. In this case, the distance between the plate 24 and the plate piece 25 can also be increased.
[0087] Therefore, it is preferable that the separation control device controls the conveying speed of at least a part of the conveying devices 21 provided between the cutting device 23 and the supporting device 11. It is more preferable that the separation control device controls the conveying speed of the conveying devices 21 in the area arranged immediately behind the cutting device 23.
[0088] However, the conveying devices 21 controlled by the separation control device are not limited to the above range. For example, the control may be performed on the conveying devices 21 in an area immediately behind the support device 11, where an increase in the conveying speed of the plate pieces 25 does not affect the operation and where it is required to increase the distance between the plate pieces 25.
[0089] The remote control device can include a CPU, which is an arithmetic processing unit for performing calculations necessary for control, RAM and ROM, which are main storage devices, an auxiliary storage device, an input / output interface, a display device, which is an output device, etc. The CPU, main storage device, auxiliary storage device, input / output interface, and output device possessed by the remote control device can be interconnected by a bus. All of the above components possessed by the remote control device do not need to be housed in the same housing; for example, the auxiliary storage device and display device may be provided externally. The auxiliary storage device is a storage device such as an SSD or HDD.
[0090] Note that CPU stands for Central Processing Unit, RAM stands for Random Access Memory, ROM stands for Read Only Memory, SSD stands for Solid State Drive, and HDD stands for Hard Disk Drive.
[0091] The input / output interface may be a wired or wireless interface for exchanging measurement data or control variables, such as an interface for exchanging control variables for the conveying speed of the conveying device 21.
[0092] Examples of the input / output interface include user interfaces such as a touch panel, keyboard, and operation buttons for selecting control conditions.
[0093] The separation control device can be configured with a personal computer (PC) or the like. Therefore, the above-mentioned components of the separation control device may be realized by software and hardware working together when a CPU executes a pre-stored program in an information processing device such as a personal computer. Note that the deceleration control device described below can also be configured in the same way, so a description of the deceleration control device will be omitted.
[0094] When the sampling device 10 of this embodiment has a separation control device and a deceleration control device, they may be integrated into one control device.
[0095] The sampling device 10 of this embodiment may also have a control device for controlling the operation of the displacement device 12, the first movement device 1131 of the counterweight 113, the second movement device 133 of the discharge device 13, the rotation device 143 of the stopper 14, etc. Such control devices can also be configured in the same way as described for the separation control device, and therefore description thereof will be omitted. The control devices for controlling the displacement device 12, etc. may also be combined with the separation control device, etc. into a single control device, or each control device may be provided individually, or only some of the control devices may be combined to provide multiple control devices. When the sampling device 10 of this embodiment has multiple control devices, the sampling device 10 of this embodiment may also have wired or wireless signal lines, etc. between the control devices so that data regarding control variables, etc. can be exchanged between the control devices.
[0096] The sampling device 10 may further include a reduction device 28 that reduces the conveying speed of the plate piece 25 in an area along the conveying path 26 of the plate piece 25, including at least a portion upstream of the support device 11.
[0097] In the sampling device 10 of this embodiment, the support device 11 supports the plate piece 25 being transported, and the displacement device 12 pushes up the position of the support device 11 to perform sampling. However, depending on the transport speed of the plate piece 25, when held by the support device 11, the inertia of the plate piece 25 being transported may cause the plate piece 25 to move significantly on the support member 111 of the support device 11.
[0098] Therefore, the sampling device 10 of this embodiment may also have a speed reducer 28 that reduces the conveying speed of the plate piece 25 in a region along the conveying path 26 of the plate piece 25, including at least a portion upstream of the support device 11. By having the speed reducer 28, the sampling device 10 can reduce the speed of the plate piece 25 when pushed up, and therefore, when supported by the support device 11 and the displacement device 12, the stopping position of the plate piece 25 on the support member 111 can be prevented from moving significantly.
[0099] The specific configuration of the reduction gear device 28 is not particularly limited, but the reduction gear device 28 may have a deceleration control device that slows down the conveying speed of the plate piece 25 by the conveying device 21 in an area along the conveying path 26 of the plate piece 25, including at least a portion upstream of the support device 11.
[0100] The control target of the deceleration control device is not limited to the conveying device 21 in a certain area upstream of the support device 11, but can also be configured to control the conveying device 21 in the area where the support device 11 is located, for example, and adjust the conveying speed of the plate piece 25.
[0101] The degree to which the conveying speed of the plate piece 25 is slowed down by the speed reduction device 28 is not particularly limited, and it is preferable to slow down the speed to an extent that can prevent the stopping position of the plate piece 25 from moving significantly on the support member 111, for example.
[0102] When the sampling device 10 of this embodiment has the speed reducer 28 together with the spacing device 27, for example, at least a part of the section of the conveying device 21 immediately after the cutting device 23 can be set as the spacing section. The spacing device 27 can have a spacing control device that controls the conveying speed of the conveying device 21 in the spacing section.
[0103] Furthermore, a section including at least a portion of the conveying device 21 between the separation section and the support device 11 may be defined as a deceleration section, and the deceleration device 28 may have a deceleration control device that decelerates the conveying speed of the conveying device 21 in the deceleration section. When the conveying device 21 is a roll conveyor, the deceleration device may have a deceleration control device that controls the conveying speed of at least a portion of the rolls 213 to 219 that constitute the roll conveyor of the conveying device 21 in the deceleration section. (9) Evaluation Device The sampling device 10 of this embodiment may further have an evaluation device that evaluates the sampled plate piece 25. The configuration of the evaluation device is not particularly limited, and may include, for example, one or more devices selected from a device that measures the size of the sampled plate piece 25, a device that measures its weight, a device that measures the angle of its corners, a device that measures its specific gravity, a device that measures its surface, or a device that measures its color.
[0104] The sampling device 10 of this embodiment described above makes it possible to easily sample the plate pieces 25 being transported. This allows the plate pieces 25 to be reliably sampled and evaluated at any timing or at a predetermined timing, which makes it possible to detect defects in the manufacturing process and contribute to reducing the defect rate.
[0105] Furthermore, the sampling device 10 of this embodiment can also sample the entire width of the plate piece 25 being manufactured and transported. This allows the sampled plate piece 25 to be evaluated across the same entire width as the semi-finished product or finished product being transported in the same way, which can more reliably detect defects in the manufacturing process and contribute to reducing the defect rate.
[0106] Furthermore, according to the sampling device 10 of this embodiment, the position of the support device 11 can be displaced by the displacement device 12, and the plate piece 25 being transported along the transport path 26 can be sampled and held. In other words, since no additional device is required to hold the sampled plate piece 25, the installation space is reduced and the device can be installed even when there is not enough space on the production line. [Plate member manufacturing device, gypsum-based building material manufacturing device] Next, an example configuration of the plate member manufacturing device and gypsum-based building material manufacturing device of this embodiment will be described.
[0107] The plate member manufacturing apparatus of this embodiment can include a sampling device according to one aspect of the present disclosure.
[0108] Furthermore, for example, a gypsum-based building material can be manufactured as the plate member, and in this case, the plate member manufacturing apparatus can also be a gypsum-based building material manufacturing apparatus. Therefore, the gypsum-based building material manufacturing apparatus of this embodiment can also be configured to include the above-mentioned sampling device.
[0109] The plate member manufacturing apparatus and the gypsum-based building material manufacturing apparatus of this embodiment can have, in addition to the sampling device 10, various devices necessary for manufacturing the plate member.
[0110] For example, when raw materials need to be mixed, the plate member manufacturing apparatus and the gypsum-based building material manufacturing apparatus of this embodiment can have a mixing device (mixer) for mixing the raw materials. Also, the plate member manufacturing apparatus and the gypsum-based building material manufacturing apparatus of this embodiment can have a molding device or the like for molding and processing the raw materials, the raw material mixture prepared in the mixing device, raw material slurry, etc. into a desired shape and size.
[0111] As an example of the configuration of the plate member manufacturing apparatus and the gypsum-based building material manufacturing apparatus of this embodiment, the configuration of the apparatus will be described below using an example in which a plate member and a gypsum board, which is a gypsum-based building material, are manufactured.
[0112] 5, a gypsum-based building material manufacturing apparatus 50 can include the sampling device 10 according to one embodiment of the present disclosure. The gypsum-based building material manufacturing apparatus 50 can further include a mixer 52, a molding device 55, and the like.
[0113] A specific configuration example of the gypsum-based building material manufacturing apparatus 50 will be described below. (1) Mixer The mixer 52 can prepare a gypsum slurry 54 containing calcined gypsum and water, and supply the gypsum slurry 54 onto the covering material 51. For this reason, the mixer 52 can be disposed at a predetermined position related to the transport path of the covering material 51, such as the first gypsum board base paper 511 and the second gypsum board base paper 512, for example, above or to the side of the transport path. Then, in the mixer 52, calcined gypsum, which is a raw material for the gypsum slurry 54, and water, and optionally further various additives and foam, are kneaded together to prepare the gypsum slurry.
[0114] Calcined gypsum, also known as calcium sulfate hemihydrate, is an inorganic composition having hydraulic properties. As the calcined gypsum, β-type calcined gypsum or α-type calcined gypsum alone, or a mixture of the two, can be used. β-type calcined gypsum is obtained by calcining in the atmosphere any one of natural gypsum, by-product gypsum, flue gas desulfurization gypsum, recycled gypsum such as waste gypsum board, or a mixture of any of these. α-type calcined gypsum is obtained by calcining in water (including in steam) any one of natural gypsum, by-product gypsum, flue gas desulfurization gypsum, recycled gypsum such as waste gypsum board, or a mixture of any of these.
[0115] When producing a gypsum-based building material, the calcined gypsum used as a raw material preferably contains β-type calcined gypsum, and it is more preferable that the main component of the calcined gypsum used as a raw material for the gypsum-based building material is β-type calcined gypsum. Note that, when the main component of the calcined gypsum used as a raw material for the gypsum-based building material is β-type calcined gypsum, this means that the β-type calcined gypsum accounts for more than 50% by mass of the calcined gypsum used as a raw material for the gypsum-based building material. When producing a gypsum-based building material, the calcined gypsum used as a raw material may be composed only of β-type calcined gypsum.
[0116] To produce α-type calcined gypsum, it is necessary to calcinate dihydrate gypsum such as natural gypsum under pressure in water or steam using an autoclave. In contrast, β-type calcined gypsum can be produced by calcining dihydrate gypsum such as natural gypsum in the atmosphere at normal pressure, and β-type calcined gypsum can be produced more productively than α-type calcined gypsum.
[0117] Examples of additives include one or more selected from adhesion improvers, inorganic fibers such as glass fibers, lightweight aggregates, fireproofing materials such as vermiculite, set retarders, set accelerators, water reducing agents, foaming agents such as sodium alkyl sulfate, alkyl ether sulfates, sodium alkylbenzene sulfonates, and polyoxyethylene alkyl sulfates, bubble size adjusters such as sulfosuccinate surfactants, water repellents such as silicone and paraffin, organic carboxylic acids, and organic carboxylates. The adhesion improver is an additive that improves the adhesion between the gypsum hardened body (hardened gypsum slurry) and the gypsum board base paper, and examples thereof include starch and polyvinyl alcohol.
[0118] The calcined gypsum and some of the additives, for example, solid additives, may be mixed and stirred in advance to form a gypsum composition, which is a mixture, and then supplied to the mixer 52 .
[0119] Also, foam can be added at gypsum slurry dispensing port 521, and the amount of foam added can be adjusted to produce gypsum slurry 54 of any density. (2) Molding Device The first gypsum board base paper 511 and the second gypsum board base paper 512 being transported inside gypsum building material manufacturing apparatus 50 reach molding device 55. Here, gypsum slurry 54 is supplied from mixer 52 through pipeline 53 between first gypsum board base paper 511 and second gypsum board base paper 512. Therefore, a continuous laminate can be formed in which a layer formed by gypsum slurry 54 is disposed between first gypsum board base paper 511 and second gypsum board base paper 512.
[0120] Specifically, for example, gypsum slurry 54 having a predetermined density is supplied and deposited on a first gypsum board base paper 511 that is continuously conveyed. Then, both widthwise ends of the first gypsum board base paper 511 are folded along predetermined score lines, extending upward and then inward, thereby partially enveloping the deposited layer of gypsum slurry 54. After this, a second gypsum board base paper 512, conveyed at the same speed, can be laid on top of the deposited layer of gypsum slurry 54 partially enveloping the first gypsum board base paper 511. Next, the gypsum board base paper 512 is passed through a molding device 55 that determines the thickness and width of the gypsum-based building material and is then molded. A gypsum-based building material can also be molded using the above procedure. In this case, a layer of gypsum slurry 54 with a certain density is formed between the first gypsum board base paper 511 and the second gypsum board base paper 512.
[0121] In this way, the molding device 55 of the gypsum-based building material manufacturing apparatus 50 can carry out a molding process for molding the gypsum slurry 54, thereby manufacturing the gypsum slurry molded body 56. (3) Rough Cutting Device, Dryer, Cutting Device The gypsum-based building material manufacturing apparatus 50 of the present embodiment can also be provided with a rough cutting device, dryer, cutting device, etc. (not shown) downstream of the molding device 55, for example, as needed.
[0122] The dryer can reduce excess moisture in the gypsum slurry molded body 56 .
[0123] Furthermore, the rough cutting device can roughly cut the produced gypsum slurry molded body 56 into a desired size.
[0124] The gypsum-based building material manufacturing apparatus 50 may have one or more rough cutting devices and cutting devices as needed. The gypsum-based building material manufacturing apparatus 50 may have, for example, a first cutting device (rough cutting device) that roughly cuts the manufactured gypsum slurry molded body 56 for installation in a dryer. The gypsum-based building material manufacturing apparatus 50 may also have a second cutting device (cutting device) that cuts the gypsum board to the size of the final product. (4) Sampling Device A sampling device 10 according to one embodiment of the present disclosure may be provided downstream of the molding device 55. The sampling device 10 can sample the plate pieces 25 being transported as needed. The plate pieces 25 that are not sampled are transported by the transport device 21 and, as needed, further processed and treated to form plate members, such as gypsum-based building materials.
[0125] 1, 2, etc., the sampling device 10 of this embodiment can also include a conveying device 21, a cutting device 23, etc. Thus, in the sampling device 10, for example, a gypsum slurry molded body 56, which is a plate 24 formed by a molding device 55, can be cut to a desired size by the cutting device to form plate pieces. The sampling device 10 of this embodiment can sample and evaluate plate pieces 25, for example, semi-finished gypsum-based building materials, being conveyed by the conveying device 21.
[0126] Calcined gypsum (hemihydrate gypsum) undergoes a hydration reaction, producing needle-shaped crystals of gypsum dihydrate, which then coagulate, solidify, and harden. Therefore, when the sampling device 10 is equipped with the cutting device 23 and the gypsum slurry molded body 56 is produced in the molding device 55 and then cut by the cutting device 23, it is preferable that the hydration reaction of the calcined gypsum has progressed sufficiently before cutting by the cutting device 23. Therefore, it is preferable to select the distance (conveyance distance) between the molding device 55 and the cutting device 23 so that the molded body has a hardness suitable for cutting by the cutting device 23.
[0127] 5 and the cutting device 23 provided in the sampling device 10, the gypsum slurry molded body 56 obtained in the molding device 55 can be hardened, and the hardened body can be cut to any size in the cutting device 23. The cutting device 23 can also be provided separately from the sampling device 10.
[0128] The configuration of the sampling device 10 has already been described, so a description thereof will be omitted here.
[0129] The number of sampling devices 10 possessed by the plate member manufacturing apparatus and gypsum-based building material manufacturing apparatus 50 of this embodiment is not limited to one, and any number of sampling devices 10 can be installed on the manufacturing apparatus line at locations where sampling or evaluation is required.
[0130] Although the plate member and the gypsum-based building material are described using an example in which gypsum boards are manufactured, the present invention is not limited to this. For example, by replacing the gypsum board base paper, which is the covering material (surface material), with glass fiber nonwoven fabric (glass tissue) or glass mat, etc. and arranging this on the surface or so as to be embedded near the surface, various gypsum-based building materials, such as glass mat gypsum boards and gypsum boards containing glass fiber nonwoven fabric, can also be manufactured.
[0131] It is also possible to manufacture various plate members other than gypsum-based building materials, such as members for electronic components, other ceramic products such as various structural materials, and resin products.
[0132] When manufacturing other ceramic products (such as slag gypsum boards and cement boards) or resin products as plate members instead of the above-mentioned gypsum-based building materials, the mixing device and molding device are not limited to the above-mentioned configurations. For example, mixing devices and molding devices with configurations appropriate for the raw materials and the products to be manufactured can be used. Furthermore, various other devices and means can be further provided as necessary.
[0133] The plate member manufacturing apparatus and gypsum-based building material manufacturing apparatus 50 of the present embodiment described above are equipped with the sampling device 10 according to one aspect of the present disclosure. This allows for easy sampling of the conveyed plate pieces 25. This allows for reliable sampling and evaluation of the plate pieces 25 at any timing or at a predetermined timing, thereby detecting defects in the manufacturing process and contributing to a reduction in the defect rate.
[0134] Furthermore, it is also possible to sample the entire width of the sampled plate piece 25. This allows the sampled plate piece 25 to be evaluated across the same entire width as the semi-finished product or finished product being transported in the same way, which in particular makes it possible to more reliably detect defects in the manufacturing process and contributes to reducing the defect rate.
[0135] Furthermore, the sampling device 10 can displace the position of the support device 11 using the displacement device 12, and sample and hold the plate piece 25 being transported along the transport path 26. In other words, since no additional device is required to hold the sampled plate piece 25, the installation space is reduced, and the device can be installed even when there is not enough space on the production line. [Notes] (1) A sampling device according to one aspect of the present disclosure includes a support device that supports a plate piece being transported by a transport device from below the plate piece, and a displacement device that vertically displaces the position of the support device, wherein the support device includes a columnar connecting member, a plurality of columnar support members arranged along the longitudinal direction of the connecting member, and a counterweight attached to the connecting member, wherein the support members are arranged so that the longitudinal direction of the connecting member and the longitudinal direction of the support member intersect, and the support members have a first end along the longitudinal direction of the support member and a second end opposite the first end, of which the first end is fixed to the connecting member, and the counterweight is arranged on the side opposite the second end of the support member, based on the position of the connecting member.

(10) In any of (1) to (9) above, the apparatus may further include a cutting device that cuts the plate into the plate pieces, and an upstream conveying device that conveys the plate and supplies it to the cutting device, and the conveying device may be disposed downstream of the cutting device along the plate piece conveying path. (11) In (10) above, the apparatus may further include a spacing device that increases the distance between the plate and the plate piece obtained by cutting using the cutting device, or the distance between the plate pieces.
