Description

Technical Field

[0001] This invention relates to sampling devices, manufacturing apparatus for board components, and manufacturing apparatus for gypsum-based building materials. Background Technology

[0002] Patent document 1 discloses a sampling device comprising: an upward pushing assembly for pushing a plate being conveyed by a conveying assembly from a position below the conveying path of the plate to a position above the conveying path; and a holding assembly for holding the plate being pushed upward by the upward pushing assembly.

[0003] <Prior art documents> <Patent Documents> Patent Document 1: International Publication No. 2018 / 193942 Summary of the Invention <Problem to be solved by this invention> Plate-shaped products containing inorganic materials such as ceramics and metals or organic and polymeric materials such as resins are manufactured by forming the raw materials into continuous strips. While conveying the molded product, various operations such as cutting and drying are performed as needed to implement continuous manufacturing.

[0004] Then, at any or predetermined time, such as by operators, samples are taken from the semi-finished products or a portion of the finished product during transport to evaluate whether a semi-finished product conforming to specifications can be manufactured. Since semi-finished products are usually transported continuously, manual sampling by operators sometimes requires skilled expertise, depending on the transport speed, size, and weight of the semi-finished products.

[0005] Therefore, the applicant invented the sampling device disclosed in Patent Document 1.

[0006] However, the sampling device disclosed in Patent Document 1 requires at least two components: a push-up component and a holding component. Therefore, the increased space required for setup, along with the length of the production line, can sometimes make setup difficult.

[0007] In view of the above-mentioned problems of the prior art, one aspect of the present invention is to provide a sampling device that can easily sample plates in transit and suppress the setting space.

[0008] <Methods for solving problems> To address the aforementioned issues, according to one aspect of the present invention, a sampling device is provided, comprising: a support device for supporting a plate sheet conveyed by a conveying device from below; and The displacement device causes the position of the support device to shift along its height. The support device includes: The connecting component has a columnar shape; Multiple support components are arranged along the long side of the connecting component and have a columnar shape; and A counterweight is mounted on the connecting component. The support member is configured such that the long side of the connecting member intersects the long side of the support member, and the first end of the first end of the support member along its long side and the second end located on the opposite side of the first end are fixed to the connecting member. The counterweight is positioned on the opposite side of the location of the second end of the support member, with the position of the connecting member as a reference.

[0009] <The Effects of the Invention> According to one aspect of the present invention, a sampling device is provided that can easily sample plates in transit and suppress the space required for installation. Attached Figure Description

[0015] Hereinafter, the implementation of the present invention will be described with reference to the accompanying drawings. However, the present invention is not limited to the following embodiments. Various modifications and substitutions can be made to the following embodiments without departing from the scope of the present invention.

[0016] In this specification, sometimes the names of components are prefixed with "first," "second," etc., for further explanation. For example, they may be referred to as "first moving device" or "second moving device." The prefixes "first" and "second" attached to the component names are solely for identification purposes to prevent confusion during description and do not indicate configuration or priority. Where there is no possibility of confusion or where it is used as a general term, it may be simply referred to as "moving device."

[0017] [Sampling device] An example of the structure of the sampling device of this embodiment will be described.

[0018] Figure 1 This is a perspective view showing the sampling device 10 of this embodiment. Figure 1 The description of the conveying device 21 has been omitted. Figure 2 This is a top view showing the case where the sampling device 10 of this embodiment is provided on the transport path 26 of the plate 25. Figure 3 , Figure 4 Indicates along Figure 2 The side view of the solid arrow 20 in the image. Figure 3 This indicates the state before the position of the support device 11 is raised by the displacement device 12. Figure 4 This indicates the state after the position of the support device 11 is raised by the displacement device 12.

[0019] exist Figures 1-4 In the diagram, the X-axis is the axis along the conveying path 26 of the plate 25, the Y-axis is the axis along the width of the plate 25, and the Z-axis is the axis along the height.

[0020] like Figure 1 As shown, the sampling device 10 of this embodiment includes a conveying device 21 for supporting the sample from below the plate 25 (see reference 21). Figure 2 The support device 11 for the plate 25 being transported, and the displacement device 12 for shifting the position of the support device 11 along the height.

[0021] (1) Conveying device, plate First, we will describe the plate sheet 25 sampled by the sampling device 10 of this embodiment, and the conveying device 21 that transports the plate sheet 25 to the sampling device 10 of this embodiment.

[0022] (Conveying device) like Figures 2-4 As shown, the conveying device 21 is not particularly limited; it can be any device capable of conveying the sheet 25 (i.e., the sheet-shaped semi-finished or finished product) and capable of accommodating the support device 11. However, a device capable of conveying the sheet 25 in the horizontal direction is preferred. The conveying device 21 is not particularly limited, but it is preferable to use a device that prevents the support member 111 from interfering with the movable part of the conveying device 21 when the position of the support device 11 is changed by the displacement device 12. Specifically, the movable part is the drive part used for conveying the sheet 25. For example, a roller conveyor or a chain conveyor can preferably be used as the conveying device 21. A roller conveyor is more preferred as the conveying device 21.

[0023] A chain conveyor is a conveyor that transports sheet metal by rotating a chain that consists of at least two rows of chains wound between multiple rollers and rotating the rollers to make the chain rotate.

[0024] Roller conveyors, such as Figures 2-4 As shown, this refers to a conveyor that arranges multiple rollers 211-220 and supports the sheet 25 by the rollers 211-220, and transports the sheet 25 by rotating the rollers 211-220. Due to the limitation of paper width, only... Figure 2 Each roller is labeled with a number.

[0025] Furthermore, the conveying device 21 may have a different structure in the part where the support device 11 is installed compared to the other parts. For example, the conveying device 21 may be configured as a roller conveyor only in the location where the support device 11 is installed, and the conveying devices 21 before and after it may be configured as conveyor belts.

[0026] The sampling device 10 of this embodiment may not include the conveying device 21 and may be composed of the support device 11, the displacement device 12, etc. described below, but it may also include the conveying device 21 as a sampling device.

[0027] (plate sheet) The sheet 25 can be in sheet form as long as it is sheet-like, and there are no particular limitations on it. For example, sheet-like semi-finished products or products whose raw materials include inorganic materials such as ceramics and metals or organic or polymeric materials such as resins can be cited. More specifically, such as gypsum building materials, which will be described later.

[0028] There are no particular limitations on the dimensions of the plate 25. Furthermore, the dimensions of the plate 25 used for sampling can be different from or the same as those of other plate 25s.

[0029] The width and length of the sheet 25 can be appropriately determined based on the type and properties of the semi-finished product or the finished product. For example, if it is a building material, a width of 450 mm or more and 1600 mm or less is preferred, and a length of 3500 mm or more and 22500 mm or less is even more preferred. There is no particular limitation on the thickness of the sheet 25. If it is too thin or too thick, it may be difficult to transport by the conveying device 21. Therefore, a thickness of 1 mm or more and 50 mm or less is preferred.

[0030] Furthermore, if the size of the sampled plate 25 is changed only relative to other unsampled plate pieces, for example, the length can be changed to more than 1 / 30 and less than 4 / 5 of the length of the unsampled plate pieces. In this case, the size of the unsampled plate pieces can be set to, for example, the range described above.

[0031] The sheet 25 is conveyed by the conveying device 21, and the area enclosed by the lower surface, upper surface, and both ends in the width direction of the conveyed sheet 25 forms the conveying path 26. In the conveying path 26, the surface formed by the lower surface of the conveyed sheet 25, that is, the surface in contact with the conveying device 21, is specifically referred to as the lower surface 26A of the conveying path 26. Additionally, the surface formed by the upper surface of the conveyed sheet 25 is also referred to as the upper surface 26B of the conveying path 26 (see reference). Figure 3 , Figure 4 ).

[0032] (2) Support device The support device 11 includes a connecting member 112 with a columnar shape, a plurality of support members 111 with columnar shapes arranged along the long side, i.e., the X-axis, of the connecting member 112, and a counterweight 113 disposed on the connecting member 112.

[0033] The components of the support device 11 will be described.

[0034] (2-1) Supporting components The support member 111 is a member that directly supports the plate 25 from below, and may have a columnar shape. Alternatively, the columnar shape may also be referred to as a rod-shaped shape. However, in this specification, the term "columnar shape" does not refer to a strictly geometric meaning; for example, it may have protrusions or recesses on its surface for connection with the connecting member 112.

[0035] The support member 111 can have a polygonal prism shape, such as a quadrangular prism, or a cylindrical shape. The support device 11 can have multiple support members 111, but not all support members 111 need to have the same shape; the shape of the support members 111 can be changed depending on their arrangement position, etc. For example, the support member 1111 positioned upstream in the conveying direction of the plate 25 can be made into a cylindrical shape (round bar) to avoid damage to the sampled plate 25.

[0036] There are no particular limitations on the material of the support member 111; for example, one or more materials selected from resin, metal, etc., can be used. However, depending on the mass of the plate 25, the support member 111 preferably has high rigidity to support the plate 25. Therefore, depending on the mass of the plate 25, the support member 111 can be made of metal, or stainless steel, aluminum, etc. The interior of the support member 111 can be hollow to avoid applying excessive load to the displacement device 12.

[0037] The support device 11 may have multiple support members 111, which may be arranged along the long side of the connecting member 112. Figure 1The support device 11 shown illustrates an example with five support members 111 arranged along the long side of the connecting member 112, but this arrangement is not limited to this method. The number of support members 111 can be selected based on the size, weight, etc., of the sampled plate 25. Furthermore, the distance between the arranged support members 111 is not particularly limited; for example, it can be a constant distance. Additionally, for example, in order to arrange the support members 111 with high density in the portion where a high load is applied when the plate 25 is placed, a structure in which the distance between the support members 111 varies depending on their position can be adopted by shortening the distance between the support members 111, etc.

[0038] The support member 111 has a first end 111A along its long side and a second end 111B located on the opposite side of the first end 111A. In the support member 111, the first end 111A of the first end 111A and the second end 111B are fixed to the connecting member 112. There is no particular limitation on the second end 111B; it can be as follows: Figure 1 , Figure 2 The free end shown is not fixed by other components.

[0039] The support member 111 can be configured such that the long side of the connecting member 112 intersects the long side of the support member 111, and preferably is configured such that the long side of the connecting member 112 is orthogonal to the long side of the support member 111. Furthermore, the term "orthogonal" does not imply a strict geometric interpretation; it simply means within a range that can be considered orthogonal. For example, an angle between the long side of the support member 111 and the long side of the connecting member 112 of 80 degrees or more and less than 100 degrees can be considered orthogonal.

[0040] Furthermore, when the multiple support members 111 are in their lowest position due to the positional change of the support device 11, they can be accommodated between the rollers of the conveying device 21. Therefore, it is preferable that the multiple support members 111 are arranged side by side to avoid interference between the support members 111 and the rollers of the conveying device 21.

[0041] exist Figure 1 , Figure 3 , Figure 4 In this configuration, multiple support members 111 are arranged at the same height, but are not limited to this. For example, the multiple support members 111 may be arranged such that the support member 1112 located downstream of the conveying path 26 of the plate 25 is higher than the support member 1111 located upstream of the conveying path 26 of the plate 25, and is fixed to the connecting member 112.

[0042] That is, the support members 111 can be configured such that the surface formed by the plurality of support members 111 for mounting the plate sheet 25 is an inclined surface, and the support members 111 are configured to rise along the downstream side of the conveying path 26 of the plate sheet 25. By configuring the plurality of support members 111 to rise along the downstream side of the conveying path 26 of the plate sheet 25, an inclined surface can be formed on the mounting surface formed by the plurality of support members 111 when the plate sheet 25 is sampled. Therefore, when the plate sheet 25 is sampled by the sampling device 10 of this embodiment, it is possible to prevent the plate sheet 25 conveyed by the conveying device 21 from shifting above the plurality of support members 111 due to inertia. Thus, the sampling device 10 of this embodiment can sample the plate sheet 25 more reliably.

[0043] The support member 111 may have a friction member 15 in at least a portion of its contact area with the plate 25. By providing the friction member 15, when the plate 25 is sampled by the sampling device 10 of this embodiment, the plate 25 conveyed by the conveying device 21 can be prevented from shifting off above the plurality of support members 111 due to inertia. Therefore, the sampling device 10 of this embodiment can sample the plate 25 more reliably.

[0044] There are no particular limitations on the friction component 15. Compared to the case where the friction component 15 is not provided, any material that can increase the friction between the surface of the support component 111 and the plate 25 is acceptable, such as rubber or fine powder. In addition, it is preferable to select the material of the friction component 15 according to the material of the plate 25 to avoid damage to the surface of the sampled plate 25.

[0045] (2-2) Connecting components Connecting component 112 is a component used to connect and support supporting component 111 and counterweight 113, and may have the following characteristics: Figure 1 The columnar shape shown. Alternatively, the columnar shape can also be called a rod-shaped shape. Similar to the case of the support member 111, the columnar shape of the connecting member 112 does not necessarily represent a strictly geometric design; it may have irregularities or protrusions for connecting with other members, etc.

[0046] The connecting component 112 may have a polygonal prism shape or a cylindrical shape, such as a quadrangular prism shape.

[0047] There are no particular limitations on the material of the connecting member 112; for example, one or more materials selected from resin, metal, etc., can be used. However, depending on the mass of the plate 25, the connecting member 112 preferably has high rigidity to support the plate 25. Therefore, depending on the mass of the plate 25, the connecting member 112 can be made of metal, or stainless steel, aluminum, etc., can be used. The interior of the connecting member 112 can be hollow to avoid excessive load being applied to the displacement device 12.

[0048] By displacing the connecting member 112 by the displacement device 12, the positions of the support member 111 and the counterweight 113 provided on the connecting member 112 can also be displaced.

[0049] (2-3) Counterweight The inventors of this invention have studied a sampling device that supports a plate sheet 25 using a support device 11 consisting of a support member 111 and a connecting member 112, and that allows the position of the support device 11 to be displaced along its height using a displacement device 12, while holding the plate sheet 25 by the support device 11. According to this sampling device, there is no need to separately provide a device for holding the plate sheet 25 being sampled, thereby reducing the space required for setting up the sampling device.

[0050] However, if the plate 25 is supported by the support device 11 and the position of the support device 11 is changed by the displacement device 12, over time, the support device 11 will tilt towards the support member 111 that holds the plate 25, and a load will be applied to the drive part of the displacement device 12. In addition, depending on the tilt angle, sometimes the position of the plate 25 on the support member 111 may change, or the support member 111 may interfere with the transport path of the plate 25.

[0051] Therefore, the support device 11 may also have a counterweight 113.

[0052] The counterweight 113 can be positioned on the opposite side to the location of the second end 111B of the support member 111, with the position of the connecting member 112 as a reference. That is, in Figures 1-4 In the middle, when viewed along the Y-axis, with the connecting member 112 as the reference, the counterweight 113 is positioned opposite to the second end 111B of the support member 111.

[0053] By setting the counterweight 113, a load balance can be maintained among the support member 111, the plate 25 disposed on the support member 111, and the counterweight 113. Therefore, it is possible to prevent the support device 11 from tilting towards the support member 111, thereby preventing problems such as the load being applied to the displacement device 12, displacement of the plate 25 on the support member 111, and interference of the support member 111 with the conveying path 26 of the plate 25.

[0054] There is no particular limitation on the number of counterweights 113. There can be one, and the support device 11 can also have multiple counterweights 113 along the long side of the connecting part 112.

[0055] The support device 11 has multiple counterweights 113 along the long side of the connecting member 112, which makes it easier to maintain the balance between the support member 111 and the plate 25 placed on the support member 111 throughout the entire range of the support member 111.

[0056] There are no particular limitations on the structure of the counterweight 113; for example, it can be a fixed type where the hammer's position remains unchanged, or a movable type where the hammer's position changes. That is, as... Figure 1 , Figure 2 As shown, the counterweight 113 may also have a first moving device 1131 for changing the distance to the connecting member 112, and the position of the hammer may be movable. The first moving device 1131 is a device for moving the position of the hammer on the counterweight 113 to change the distance to the connecting member 112. By having the first moving device 1131, the counterweight 113 can control the balance between the support member 111 and the plate 25 mounted on the support member with high precision. The first moving device 1131 may be a device for manually moving the position of the hammer, or a device for automatically moving the position of the hammer by means of an actuator or the like.

[0057] Regarding the first moving device 1131, when it serves as a device for automatically moving the position of the hammer, there are no particular limitations on its structure. The first moving device 1131 can, for example, be a structure combining a linear guide (linear guide section), a linear shaft, a linear bearing, and other linear motion mechanisms with a linear motor, a motor, or other drive device. Furthermore, the counterweight 113 may also include, for example, a control device that automatically moves the hammer's position and controls its tilt based on the tilt of the support device 11.

[0058] (3) Displacement device The displacement device 12 can displace the position of the support device 11 along the height, i.e., the Z-axis.

[0059] There are no particular limitations on the configuration of the displacement device 12. For example, it can be pre-connected to any position of the support device 11 to allow the position of the support device 11 to be displaced. The displacement device 12 can be connected to the connecting member 112, for example, and disposed below the connecting member 112.

[0060] By connecting the displacement device 12 to the connecting member 112, the position of the connecting member 112 is changed, and the positions of the support member 111 and the counterweight 113 provided on the connecting member 112 are also changed.

[0061] Before taking samples, such as Figure 3 As shown, the positioning device 12 can pre-position the support member 111 of the support device 11 at a position lower than the lower surface 26A of the conveying path 26 of the plate 25. In this case, the support member 111 of the support device 11 can be configured in a way that does not interfere with the movable part of the conveying device 21. When the conveying device 21 is a roller conveyor, the support member 111 can be arranged side-by-side with the rollers 211 to 220 of the roller conveyor.

[0062] Furthermore, during sampling, the displacement device 12 can push the support device 11 upward, causing the support member 111 to move above the upper surface 26B of the conveying path 26. In addition, the displacement device 12 preferably adjusts and selects the position of the support device 11 to avoid interference between the subsequent plate and the support device 11.

[0063] After the sampled plate 25 is discharged to the outside by the discharge device 13, the displacement device 12 can displace the support member 111 of the support device 11 to a position lower than the lower surface 26A of the conveying path 26 of the plate 25, in preparation for the next sampling.

[0064] There are no particular limitations on the structure of the displacement device 12, and it can be one or more selected from electric actuators, hydraulic cylinders, pneumatic cylinders, etc. In particular, in order to sample the plate 25 during transport, it is preferable to have a faster lifting speed, so a pneumatic cylinder is preferred.

[0065] like Figure 3 , Figure 4 As shown, the displacement device 12 preferably displaces the support device 11 vertically relative to the conveying path 26 of the plate 25. By displacing the support device 11 vertically relative to the conveying path 26, the displacement device 12 can particularly suppress the installation space for the sampling device 10, which includes the support device 11 and the displacement device 12.

[0066] The displacement device 12 causes the support device 11 to be vertically displaced relative to the conveying path 26 of the plate 25, meaning it is vertically displaced relative to the upper surface 26B or the lower surface 26A of the conveying path 26. The term "vertical" is not strictly geometric; considering the accuracy of the displacement device 12, it includes a range that can be considered vertical. Therefore, for example, when the angle between the upper surface 26B or the lower surface 26A of the conveying path 26 is 80 degrees or more and 100 degrees or less, it can be considered vertical. Preferably, the angle is 85 degrees or more and 95 degrees or less.

[0067] There is no particular limitation on the timing of the displacement device 12 pushing the support device 11 upward. For example, it can be configured such that the support device 11 is pushed upward by the displacement device 12 after the operator has visually confirmed that the plate 25 is located on the support member 111.

[0068] Furthermore, the displacement device 12 can be configured to automatically push up the support device 11 according to a predetermined timing. For example, it can be configured to push up the support device 11 by the displacement device 12 after a predetermined time has elapsed following the operation of the cutting device 23 (described later). It can also be configured to push up the support device 11 by the displacement device 12 after various sensors detect that the plate 25 is located on the support member 111.

[0069] (4) Discharge device The plate 25, which is sampled by the sampling device 10 of this embodiment and placed on the support member 111, can also be sampled manually by the operator.

[0070] The sampling device 10 may also have a discharge device 13, which discharges the plate 25, which is sampled by being supported by the support device 11 and moved together with the displacement device 12 above the transport path 26 of the plate 25, from the support device 11.

[0071] There are no particular limitations on the structure of the discharge device 13. For example, it may have multiple discharge components 132 and a fixing component 131 for fixing the multiple discharge components 132. In addition, the discharge device 13 may have a fixing component 131 that guides the fixing component 131 along the double arrow A (see reference). Figure 1 The second moving device 133 is a device for moving the fixed member 131 and the discharge member 132.

[0072] The discharge member 132 is moved by the second moving device 133 via the fixing member 131 to contact the plate 25, for example, the plate 25 can be moved along the Y-axis, thereby discharging the plate 25 from the support device 11. Alternatively, a conveying device for conveying the sampled plate 25 can be arranged in the discharge direction to further convey the discharged plate 25 to a desired position.

[0073] There are no particular limitations on the structure of the second moving device 133. It can be a structure that combines a linear guide rail (linear guide part), a linear shaft, a linear bearing and other direct-acting mechanisms with a linear motor, a motor and other drive devices.

[0074] Discharge device 13 Figure 3 , Figure 4 As shown, it is preferably positioned so as not to interfere with the plate 25 or the like conveyed by the conveying device 21 along the conveying path 26.

[0075] The structure of the discharge device 13 is not limited to the above structure. For example, it can be configured to provide rollers or the like on the surface of the support member 111 opposite to the plate 25 so that the plate 25 can be conveyed and discharged along the long side of the support member 111.

[0076] (5) Stopper The sampling device 10 of this embodiment may also have a stopper 14 downstream of a plurality of support members 111 along the transport path 26 of the plate 25.

[0077] The stopper 14 is a component that restricts the movement of the plate 25 sampled on the support member 111.

[0078] The sampling device 10, by having a stopper 14, prevents the plate sheet 25, conveyed by the conveying device 21, from protruding from above the plurality of support members 111 due to inertia when sampling the plate sheet 25 by the sampling device 10 of this embodiment. Therefore, the sampling device 10 of this embodiment can sample the plate sheet 25 more reliably.

[0079] There are no particular limitations on the construction of the stopper 14. It can include a limiting member 141 that directly or indirectly contacts the plate 25 sampled on the support member 111 and restricts the movement of the plate 25. There are no particular limitations on the structure of the limiting member 141, as long as it is a structure capable of restricting the movement of the sampled plate 25. For example, it can have… Figure 1 The plate-shaped component shown may also have one or more column-shaped components, etc.

[0080] The stopper 14 may also have an elastic member 142 on the surface of the limiting member 141 opposite to the plate 25. The elastic member 142 may be made of a material that can absorb impact, such as various types of rubber, sponge, etc.

[0081] The stopper 14, by having an elastic member 142, is able to prevent the plate 25 from breaking even when the plate 25 comes into contact with the limiting member 141 of the stopper 14.

[0082] The stopper 14 is preferably used, for example, when sampling a plate 25 that easily slides on the support member 111, so that sampling can be easily performed on the support member 111. However, it is not suitable for use on a sliding plate 25 that does not slide easily. This is to prevent the plate 25 from being damaged after sampling.

[0083] Therefore, the stop 14 may also include a rotating device 143, which, when the stop 14 is not used, for example, causes the limiting member 141 to move along... Figure 1The double arrow B in the middle rotates, thereby enabling the limiting member 141 to be in a state where it is not in contact with the plate 25. The rotating device 143 is a device for rotating the limiting member 141 and the elastic member 142. By rotating the limiting member 141 by the rotating device 143, when the plate 25 on the support member 111 moves to the position of the stopper 14, it is possible to switch between the state in which the plate 25 is in contact with the limiting member 141 and the state where it is not in contact.

[0084] As the rotating device 143, a device that can rotate the limiting member 141 by a predetermined angle can be used, such as a rotary actuator. Furthermore, when the stopper 14 has an elastic member 142, it is preferable that the rotating device 143 can rotate the elastic member 142 together with the limiting member 141.

[0085] There are no particular limitations on the power source for the rotating device 143; for example, a rotary actuator driven by any power source selected from electric, pneumatic (air-driven), etc., can be used. When a pneumatic rotary actuator is used as the rotating device 143, the air inside the rotary actuator can absorb the impact when the plate 25 directly or indirectly contacts the limiting member 141, thus enabling the rotating device 143 to perform an impact absorption function. Therefore, a pneumatic rotary actuator is preferably used as the rotating device 143.

[0086] (6) Stent The support device 11, displacement device 12, discharge device 13, and stopper 14 can be separate and unconnected independent devices, or they can be like... Figure 3 , Figure 4 As shown, a structure is provided with a bracket 31 and connected to the bracket 31.

[0087] By using bracket 31 to integrate the support device 11, the displacement device 12, the discharge device 13, and the stopper 14 into a single unit, it is easy to install and adjust them on the conveying device 21, etc. Casters and other moving devices for the bracket can also be pre-installed on bracket 31 as needed.

[0088] (7) Cutting device, upstream conveying device The sampling device 10 of this embodiment may also have a cutting device 23 and an upstream side conveying device 22 upstream of the conveying device 21 described above.

[0089] The sampling device 10 of this embodiment may further include a cutting device 23 for cutting the plate 24 to form a plate sheet 25, and an upstream conveying device 22 for conveying the plate 24 and providing it to the cutting device 23. In this case, the conveying device 21 can be positioned downstream of the cutting device 23 along the conveying path 26 of the plate sheet 25. When it is necessary to specifically distinguish between the conveying device 21 and the upstream conveying device 22, the conveying device 21 may also be referred to as the downstream conveying device.

[0090] Furthermore, the plate 24, for example, is a strip-shaped semi-finished product or product obtained by molding raw materials, and is a conveyed material before being cut into plate sheets 25. By cutting the plate 24, a portion of the plate 24 can be separated into plate sheets 25. In addition, by cutting the plate 24 multiple times, multiple plate sheets 25 can be formed.

[0091] There is no particular limitation on the shape of the cutting line when cutting the plate 24. For example, it can be a cutting line parallel to the wide side of the plate 24, that is, a cutting line perpendicular to the conveying direction of the plate 24. Therefore, the plate 24 can have a shape that is longer in the conveying direction than the cut plate sheet 25, such as the strip shape described above.

[0092] There are no particular limitations on the structure of the cutting device 23. For example, a cutting device that can cut the conveyed plate 24 along a cutting line parallel to the width direction of the plate 24 can be used. Specifically, a rotary cutter, a rotary saw, etc., can be used, for example.

[0093] Furthermore, the cutting line can be, for example, a cutting line parallel to the conveying direction of the plate 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 capable of cutting the plate 24 along a cutting line parallel to the conveying direction of the plate 24 or a cutting line of any shape can be used.

[0094] The displacement device 12 can be configured to operate in conjunction with the cutting device 23. For example, it can be configured such that after a predetermined number of cuts by the cutting device 23 and after a predetermined time, the displacement device 12 pushes the support device 11 upward to take a sample.

[0095] Regarding the upstream conveying device 22, any device capable of conveying the plate 24 and supplying it to the cutting device 23 is acceptable, and its structure is not particularly limited. For example, one or more types selected from roller conveyors, belt conveyors, chain conveyors, etc., can be used. In addition, the conveying device 21 and the upstream conveying device 22 described above can be the same conveying device or different conveying devices.

[0096] (8) Separation device, deceleration device In the case where the sampling device 10 of this embodiment has a cutting device 23, the sampling device 10 may also include a separating device 27, which is used to increase, for example, the distance between the plate 24 and the plate piece 25 obtained by cutting by the cutting device 23, or the distance between the plate pieces 25.

[0097] Separation device 27 and deceleration device 28 (described later) are only shown in Figure 2 The descriptions in the other attached figures are omitted.

[0098] When the plate body 24 is cut by the cutting device 23 to form plate pieces 25, there is almost no distance between the continuously conveyed plate pieces 25 obtained immediately after the cutting device 23, and they are close to each other. Therefore, depending on the conveying speed of the plate pieces 25 when conveying by the conveying device 21, it is sometimes necessary to increase the moving speed of the displacement device 12 on the support device 11 when sampling the plate pieces 25 by the support device 11 to avoid contact with subsequent plate pieces 25.

[0099] In contrast, by having a separation device 27 for increasing the distance between the plate 24 and the plate piece 25 or the distance between the plate pieces 25, sampling can be performed more easily without excessively increasing the moving speed of the support device 11.

[0100] There are no particular limitations on the specific structure of the separation device 27. For example, the separation device 27 may have a separation control device for controlling the conveying speed of the conveying device 21 for at least a part of the conveying device 21 to convey the plate 25.

[0101] like Figure 2 As shown, the separation control device of the separation device 27 preferably controls at least a portion of the conveying device 21 to make the conveying speed of the plate 25 faster than that of the upstream region of the conveying device 21, i.e., to accelerate it. This upstream region is, for example, the region immediately preceding it. For example, if the conveying device 21 is a roller conveyor, the separation control device can control at least a portion of the rollers 211 and 212 constituting the conveying device 21 to accelerate the conveying speed.

[0102] The separating device 27 can, for example, increase the distance between the plate pieces 25 cut by the cutting device 23. Therefore, the separating control device is preferably configured to, for example, control the speed at which a portion of the conveying device 21, controlled by the separating control device, conveys the plate pieces 25 faster than the conveying speed of the upstream conveying device 22, located upstream of the cutting device 23, conveys the plate 24.

[0103] By configuring the separation control device as described above, after the plate piece 25 is provided to the conveying device 21 via the cutting device 23, until the next plate piece 25 is provided to the conveying device 21, the plate piece 25 previously provided to the conveying device 21 can be conveyed to a position with a considerable forward distance. Therefore, for the plate pieces 25 that have already been conveyed by the conveying device 21, the distance between the plate pieces 25 obtained by cutting by the cutting device 23 can be sufficiently increased. In addition, in this case, the distance between the plate 24 and the plate piece 25 can also be increased.

[0104] Here, the separation control device preferably controls the conveying speed of at least a portion of the conveying device 21, for example, that is disposed between the cutting device 23 and the support device 11. The separation control device is particularly preferably controlling the conveying speed of the conveying device 21 in the area immediately following the cutting device 23.

[0105] Here, the conveying device 21 controlled by the separation control device is not limited to the above-described scope. For example, it can also be used to control the conveying device 21 in areas such as those immediately following the support device 11, where the operation is not affected even if the conveying speed of the plate pieces 25 is increased, and where it is necessary to increase the distance between the plate pieces 25.

[0106] A separate control device may include a CPU as an arithmetic processing unit for performing the calculations required for control, RAM or ROM as main storage, an auxiliary storage device, an input / output interface, and a display device as an output device. The CPU, main storage device, auxiliary storage device, input / output interface, and output device of the separate control device can be interconnected via a bus. Not all of the above components of the separate control device need to be housed in the same enclosure; for example, the auxiliary storage device or display device can be located externally. The auxiliary storage device is a storage device such as an SSD or HDD.

[0107] CPU stands for Central Processing Unit, RAM for Random Access Memory, and ROM for Read Only Memory. Additionally, SSD stands for Solid State Drive, and HDD stands for Hard Disk Drive.

[0108] As input / output interfaces, examples include wired or wireless interfaces used for processing measurement data and control quantities. For example, interfaces used for processing control quantities such as the conveying speed of the conveying device 21 can also be used as input / output interfaces.

[0109] As input / output interfaces, other examples include user interfaces such as touchpads, keyboards, and operation buttons used to select control conditions.

[0110] The separation control device can be composed of a personal calculator (PC) or the like. Therefore, the aforementioned components of the separation control device can also be implemented through a combination of software and hardware by executing a pre-stored program in the CPU within an information processing device such as a personal calculator. Furthermore, the deceleration control device described below can also have the same structure; therefore, this part of the deceleration control device will be omitted from the description.

[0111] In the case where the sampling device 10 of this embodiment has a separation control device and a deceleration control device, it can also be summarized as a single control device.

[0112] The sampling device 10 of this embodiment may further include a control device for controlling the operation of the displacement device 12, the first moving device 1131 having a counterweight 113, the second moving device 133 having a discharge device 13, and the rotating device 143 having a stopper 14. This control device may also have the same structure as the separation control device, therefore its description is omitted. Regarding the control device for controlling the displacement device 12, it may be a single control device integrated with the separation control device, or each control device may be provided separately, or only a portion may be integrated, with multiple control devices provided. In the case where the sampling device 10 of this embodiment has multiple control devices, in order to enable data processing related to control quantities between the control devices, the sampling device 10 of this embodiment may also have wired or wireless signal lines between the control devices.

[0113] Additionally, the sampling device 10 may also have a deceleration device 28 for reducing the conveying speed of the plate sheet 25 in a region along the conveying path 26 of the plate sheet 25 that includes at least a portion upstream of the support device 11.

[0114] In the sampling device 10 of this embodiment, the plate 25 being transported is supported by the support device 11, and the position of the support device 11 is pushed up by the displacement device 12 to perform sampling. However, depending on the transport speed of the plate 25, when the plate 25 being transported is held by the support device 11, the plate 25 may move significantly on the support member 111 of the support device 11 due to inertia.

[0115] In this embodiment, the sampling device 10 may also include a deceleration device 28, which is used to decelerate the conveying speed of the plate sheet 25 in a region along the conveying path 26 of the plate sheet 25, including at least a portion upstream of the support device 11. By including the deceleration device 28, the sampling device 10 can decelerate the speed of the plate sheet 25 when it is pushed upward, and therefore, it can suppress large-scale movement of the stopping position of the plate sheet 25 on the support member 111 when supported by the support device 11 and the displacement device 12.

[0116] There are no particular limitations on the specific structure of the deceleration device 28. The deceleration device 28 may have a deceleration control device for decelerating the conveying speed of the plate 25 by the conveying device 21 in the area along the conveying path 26 of the plate 25, including at least a portion upstream of the support device 11.

[0117] The control object of the deceleration control device is not limited to the conveying device 21 located in a region upstream of the support device 11. For example, it can be configured to control the conveying device 21 in the region where the support device 11 is located, and adjust the conveying speed of the plate 25.

[0118] There is no particular limitation on the degree to which the deceleration device 28 reduces the conveying speed of the plate 25. For example, the plate 25 on the support member 111 is preferably decelerated to the extent that it can prevent the plate 25 from moving significantly from its stop position.

[0119] In the case where the sampling device 10 of this embodiment is equipped with both the separation device 27 and the deceleration device 28, for example, at least a portion of the section of the conveying device 21 immediately following the cutting device 23 can be used as the separation section. Furthermore, the separation device 27 may have a separation control device for controlling the conveying speed of the conveying device 21 in the separation section.

[0120] Furthermore, the section between the separation section and the support device 11, including at least a portion of the conveying device 21, is designated as a deceleration section. The deceleration device 28 may have a deceleration control device for reducing the conveying speed of the conveying device 21 within this deceleration section. If the conveying device 21 is a roller conveyor, the deceleration device may have a deceleration control device for controlling the reduction of the conveying speed of at least a portion of the rollers 213 to 219 constituting the conveying device 21 within the deceleration section.

[0121] (9) Evaluation device The sampling device 10 of this embodiment may also include an evaluation device for evaluating the sampled plate 25. There are no particular limitations on the structure of the evaluation device; for example, it may include one or more devices selected from those for measuring the size of the sampled plate 25, measuring its weight, measuring the angle of its corners, measuring its specific gravity, measuring its surface or color, etc.

[0122] According to the sampling device 10 of this embodiment described above, it is possible to easily sample the sheet 25 during transport. Therefore, the sheet 25 can be sampled and evaluated reliably at any time or at a predetermined time, thereby enabling the detection of defects in the manufacturing process and helping to reduce the defect rate.

[0123] Furthermore, according to the sampling device 10 of this embodiment, the plate sheet 25 being manufactured and transported can be sampled along its entire width. Therefore, the sampled plate sheet 25 can be evaluated along its entire width in the same way as semi-finished products or finished products being transported, enabling more accurate detection of defects in the manufacturing process and helping to reduce the defect rate.

[0124] Furthermore, according to the sampling device 10 of this embodiment, the position of the support device 11 can be changed by the displacement device 12 to sample and hold the plate 25 being conveyed on the conveying path 26. That is, there is no need to provide other devices for holding the sampled plate 25, thereby reducing the installation space required and enabling installation even when space on the production line is insufficient.

[0125] [Manufacturing equipment for board components, manufacturing equipment for gypsum-based building materials] Hereinafter, a structural example of the manufacturing apparatus for the board component and the manufacturing apparatus for gypsum-based building materials according to this embodiment will be described.

[0126] The manufacturing apparatus for the plate component according to this embodiment can have a sampling device of one aspect of this disclosure.

[0127] Furthermore, as a board component, it can also be used to manufacture gypsum-based building materials. In this case, the manufacturing apparatus for the board component can also be a gypsum-based building material manufacturing apparatus. Therefore, the gypsum-based building material manufacturing apparatus of this embodiment can also be a structure equipped with the sampling device described above.

[0128] In addition to the sampling device 10, the board component manufacturing apparatus and gypsum building material manufacturing apparatus of this embodiment may also have various devices required for manufacturing board components.

[0129] For example, when it is necessary to mix raw materials, the board component manufacturing apparatus and gypsum-based building material manufacturing apparatus of this embodiment may include a mixing device (mixer) for mixing raw materials. In addition, the board component manufacturing apparatus and gypsum-based building material manufacturing apparatus of this embodiment may also include a molding device for shaping and processing raw materials, or raw material mixtures or raw material slurries prepared by the above-mentioned mixing device, into desired shapes and sizes.

[0130] The following is a structural example of the apparatus for manufacturing board components and gypsum building materials according to this embodiment, taking the case of manufacturing gypsum plywood as a board component and gypsum building material as an example, to explain the structure of the apparatus.

[0131] like Figure 5 As shown, the gypsum building material manufacturing apparatus 50 may have a sampling device 10 in one form of this disclosure. The gypsum building material manufacturing apparatus 50 may also have a mixer 52, a molding device 55, etc.

[0132] The following is a detailed description of the structure of the gypsum building material manufacturing device 50.

[0133] (1) Mixer The mixer 52 is capable of preparing a gypsum slurry 54 containing calcined gypsum and water, and supplying the gypsum slurry 54 onto the covering material 51. Therefore, the mixer 52 can be positioned at a predetermined location related to the conveying paths of the first gypsum board base paper 511 and the second gypsum board base paper 512, which serve as the covering material 51, for example, above or beside the conveying paths. Furthermore, in the mixer 52, calcined gypsum, water, and various additives or foams added as appropriate, which are the raw materials for the gypsum slurry 54, can be mixed and prepared into a gypsum slurry.

[0134] Calcined gypsum, also known as calcium sulfate half hydrate, is an inorganic composition with hydraulic properties. Calcined gypsum can be either β-type or α-type, alone or in mixtures thereof. β-type calcined gypsum is produced by calcining any one or a combination of natural gypsum, by-product gypsum, flue gas desulfurization gypsum, and recycled gypsum such as waste gypsum board, in atmospheric conditions. α-type calcined gypsum is produced by calcining any one or a combination of natural gypsum, by-product gypsum, flue gas desulfurization gypsum, and recycled gypsum such as waste gypsum board, in water (including steam).

[0135] In the manufacture of gypsum-based building materials, the calcined gypsum used as a raw material preferably includes β-type calcined gypsum, and the main component of the calcined gypsum used as a raw material for gypsum-based building materials is preferably β-type calcined gypsum. Furthermore, the statement that the main component of the calcined gypsum used as a raw material for gypsum-based building materials is β-type calcined gypsum indicates that the mass percentage of β-type calcined gypsum in the calcined gypsum used as a raw material for gypsum-based building materials is greater than 50%. In the manufacture of gypsum-based building materials, the calcined gypsum used as a raw material may consist solely of β-type calcined gypsum.

[0136] The manufacture of α-type calcined gypsum requires the use of an autoclave to pressurize and calcine natural gypsum or similar substances in water or steam to produce dihydrate gypsum. In contrast, β-type calcined gypsum can be manufactured by calcining natural gypsum or similar substances at atmospheric pressure. Compared to α-type calcined gypsum, β-type calcined gypsum can be manufactured with better productivity.

[0137] Examples of additives include one or more selected from adhesive modifiers, inorganic fibers such as glass fiber, lightweight aggregates, refractory materials such as vermiculite, setting delay agents, setting accelerators, water-reducing agents, foaming agents such as sodium alkyl sulfate, alkyl ether sulfate, sodium alkylbenzene sulfonate, and polyoxyethylene alkyl sulfate, foam diameter modifiers of sulfosuccinate-type surfactants, waterproofing agents such as silicone and paraffin, organic carboxylic acids, and organic carboxylates. Adhesive modifiers refer to additives used to improve the adhesion between the hardened gypsum plaster (the substance that hardens gypsum slurry) and the base paper for gypsum board; examples include starch and polyvinyl alcohol.

[0138] In addition, calcined gypsum and some additives, such as solid additives, can be pre-mixed and stirred into a mixture and supplied to mixer 52 as a gypsum composition.

[0139] In addition, by adding air bubbles through the gypsum slurry outlet 521 and adjusting the amount of air bubbles added, gypsum slurry 54 of any density can be formed.

[0140] (2) Molding device The first gypsum board base paper 511 and the second gypsum board base paper 512, conveyed within the gypsum building material manufacturing apparatus 50, arrive at the molding apparatus 55. Here, gypsum slurry 54 is supplied from the mixer 52 via pipe 53 between the first gypsum board base paper 511 and the second gypsum board base paper 512. Therefore, a continuous laminate containing layers of gypsum slurry 54 can be formed between the first gypsum board base paper 511 and the second gypsum board base paper 512.

[0141] Specifically, for example, gypsum slurry 54 of a predetermined density is provided and deposited on a continuously conveyed first gypsum board base paper 511. Furthermore, the two ends of the first gypsum board base paper 511 in the width direction are bent along predetermined lines, extending upwards and then inwards, thereby covering a portion of the deposited layer of gypsum slurry 54. Then, a second gypsum board base paper 512, conveyed at the same speed, is overlapped on the deposited layer of gypsum slurry 54 partially covered by the first gypsum board base paper 511. The overlapped material is then formed by a forming device 55 for determining the thickness and width of the gypsum board. Through these steps, gypsum-based building materials can also be formed. In this case, a layer of gypsum slurry 54 of a certain density can be formed between the first gypsum board base paper 511 and the second gypsum board base paper 512.

[0142] As described above, in the molding apparatus 55 of the gypsum building material manufacturing apparatus 50, a molding process for molding gypsum slurry 54 can be performed, thereby manufacturing a gypsum slurry molded body 56.

[0143] (3) Coarse cutting device, dryer, cutting device The gypsum building material manufacturing apparatus 50 of this embodiment may also be provided, as needed, for example, with a coarse cutting device, a dryer, a cutting device, etc. (not shown) on the downstream side of the molding device 55.

[0144] The use of a dryer can reduce excess moisture in the gypsum slurry molded body 56.

[0145] In addition, the manufactured plaster slurry molded body 56 can be coarsely cut into the desired size using a coarse cutting device.

[0146] The gypsum-based building material manufacturing apparatus 50 may be equipped with one or more coarse cutting devices and cutting devices as needed. For example, for the purpose of placing the manufactured gypsum slurry molded body 56 inside a dryer, the gypsum-based building material manufacturing apparatus 50 may have a first cutting device (coarse cutting device) for coarse cutting. Additionally, the gypsum-based building material manufacturing apparatus 50 may have a second cutting device (cutting device) for cutting gypsum boards according to the final product dimensions.

[0147] (4) Sampling device Downstream of the forming device 55, a sampling device 10 of one form disclosed herein may be provided. The sampling device 10 may sample the sheet 25 being transported as needed. In addition, the sheet 25 that has not been sampled is transported by the conveying device 21 and further processed and treated as required to become a board component, such as a gypsum building material.

[0148] The sampling device 10 of this embodiment, as shown in reference... Figure 1 , Figure 2 The description may also include the conveying device 21, the cutting device 23, etc. Therefore, in the sampling device 10, for example, the gypsum slurry molded body 56, which is a plate 24 formed by the molding device 55, can be cut into arbitrary sizes as plate sheets using the cutting device. Furthermore, the sampling device 10 of this embodiment can sample and evaluate the plate sheets 25, such as semi-finished products of gypsum building materials, which are conveyed by the conveying device 21.

[0149] Calcined gypsum (hemihydrate gypsum) undergoes a hydration reaction to form needle-like crystals of dihydrate gypsum, which then harden through coagulation and solidification. Therefore, when the sampling device 10 is equipped with a cutting device 23, and the gypsum slurry molded body 56 is manufactured 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 the cutting device 23 cuts it. 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 suitable hardness for cutting by the cutting device 23.

[0150] As mentioned above, in Figure 5 The gypsum building material manufacturing apparatus 50 shown has a molding device 55 and a cutting device 23 in the sampling device 10. The gypsum slurry molded body 56 obtained by the molding device 55 can be hardened, and the hardened body can be cut into any size in the cutting device 23. Furthermore, the cutting device 23 can be provided separately from the sampling device 10.

[0151] The structure of the sampling device 10 has been described above and will not be repeated here.

[0152] The number of sampling devices 10 included in the board component manufacturing apparatus and gypsum building material manufacturing apparatus 50 according to this embodiment is not limited to one; any number can be set at the location on the production line of the manufacturing apparatus where sampling and evaluation are required.

[0153] Furthermore, the example of manufacturing gypsum plywood as a board component and gypsum-based building material is provided, but this method is not the only one. For example, by replacing the base paper of the gypsum plywood used as a covering material (surface material) with glass fiber nonwoven fabric (glass fiber mat), glass fiber mat, etc., and placing it on the surface or embedding it near the surface, various gypsum-based building materials can be manufactured, such as glass mat gypsum board, gypsum board containing glass fiber nonwoven fabric, etc.

[0154] In addition, it can also manufacture various board components other than gypsum building materials, such as electronic components, various structural materials, and other ceramic and resin products.

[0155] When manufacturing other ceramic products (slag gypsum board, cement board, etc.) or resin products that are not gypsum-based building materials, such as those mentioned above, the mixing and molding apparatus are not limited to the structures described above. For example, a mixing and molding apparatus with an appropriate structure can be used depending on the raw materials or the articles being manufactured. Furthermore, various other devices and components can be incorporated as needed.

[0156] The panel component manufacturing apparatus and gypsum-based building material manufacturing apparatus 50 of the present embodiment described above have a sampling device 10 according to one aspect of this disclosure. Therefore, it is possible to easily sample the panel sheet 25 during transport. As a result, the panel sheet 25 can be sampled and evaluated reliably at any time or at a predetermined time, thus enabling the detection of defects in the manufacturing process and helping to reduce the defect rate.

[0157] Furthermore, the sampling plate 25 can also be sampled along its entire width. Therefore, the entire width of the sampling plate 25, which is the same as that of the semi-finished product or product being transported, can be evaluated, and defects in the manufacturing process can be detected more accurately, thereby helping to reduce the defect rate.

[0158] Furthermore, the sampling device 10 repositions the support device 11 via the displacement device 12, thereby enabling it to sample and hold the plate 25 being conveyed on the conveying path 26. That is, no additional device is required to hold the sampled plate 25, thus minimizing installation space and allowing it to be installed even when space on the production line is limited.

[0159] [Postscript] (1) A sampling device according to one aspect of the present disclosure includes: a support device for supporting a plate sheet conveyed by a conveying device from below; and The displacement device causes the position of the support device to shift along its height. The support device includes: The connecting component has a columnar shape; Multiple support components are arranged along the long side of the connecting component and have a columnar shape; and The counterweight is mounted on this connecting component. The support member is configured such that the long side of the connecting member intersects the long side of the support member, and the first end is fixed to the connecting member at a first end along the long side of the support member and at a second end located on the opposite side of the first end. The counterweight is positioned on the opposite side of the location of the second end of the support member, with the position of the connecting member as a reference.

[0160] (2) In (1) above, the counterweight may also have a first moving device for changing the distance to the connecting component.

[0161] (3) In (1) or (2) above, the support device may also have a plurality of the counterweights along the length of the connecting member.

[0162] (4) In any of (1) to (3) above, the displacement device may be connected to the connecting member and disposed below the connecting member.

[0163] (5) In any of (1) to (4) above, the displacement device may also cause the support device to be vertically displaced relative to the conveying path of the plate.

[0164] (6) In any of (1) to (5) above, the support member may have a friction member in at least a portion of the part that contacts the plate.

[0165] (7) In any of (1) to (6) above, a plurality of the support members may be fixed to the connecting member such that the support member located downstream of the conveying path of the plate is higher than the support member located upstream of the conveying path of the plate.

[0166] (8) In any of (1) to (7) above, the sampling device may also have a discharge device that discharges the plate sampled by being supported by the support device and moving together with the support device to the upper part of the transport path of the plate.

[0167] (9) In any of (1) to (8) above, a stop may also be provided downstream of the plurality of support members along the transport path of the plate.

[0168] (10) Any of (1) to (9) above may further include: a cutting device for cutting the plate into the plate pieces; and An upstream conveying device transports the plate and supplies it to the cutting device.
