An embodiment of a control device, a control method, a program, and a transport system according to the present invention will be described in detail below with reference to the accompanying drawings.

The control device of the present embodiment controls a separation device that conveys an object to be conveyed such as a prepreg. The control device determines the execution order of the plurality of jobs based on the attribute information of the transported object processed by each of the plurality of jobs. When determining the execution order, the influence of processes other than the carrying process such as the cleaning process is considered. For example, the execution order is determined so that the number of cleaning processes is minimized. Thereby, the transported object can be transported more efficiently.

The cleaning step is a step of cleaning the inside of the apparatus in order to prevent dust from entering. Although dust of the prepreg may be generated when the prepreg is conveyed, it may not be desirable that the dust generated from another prepreg made of a different material adheres to the prepreg. For this purpose, a cleaning process is performed.

In addition to the cleaning process, a process of changing the unit arrangement may be considered. Details of the unit arrangement replacement process will be described later. The cleaning process and the unit arrangement changing process may be executed by the user or may be executed by a means having a function of realizing each process.

In the present embodiment, the case where the transported object is a prepreg will be described as an example. The prepreg is an example of an object to be transferred, and includes a thin plate-shaped or sheet-shaped member that can be transferred by the transfer system of this embodiment. Items to be conveyed include resins, protective paper on the front and back surfaces, metal foil such as copper foil, electronic circuit board materials that have been plated, paper, special films, plastic films, and sheets for electronic circuit boards such as prepreg. Can be included. The transported object transported by the transportation system is not limited to the prepreg.

Specifically, the transported object is an object that can be transported by the transportation system and is loaded. The shape of the transported object is not limited, and may be a sheet shape or a three-dimensional object. In the present embodiment, a case where the transported object is a sheet will be described.

The transport system according to the present embodiment is particularly useful for transporting an object having the following characteristics. Specifically, it is preferable that the object to be transported is a substance that requires careful handling during transportation and loading due to characteristics such as fragility, ignition property, and flexibility.

The prepreg is a semi-curable sheet-shaped member. It is known that prepreg is weak against scratches (low in abrasion resistance), highly ignitable, and highly flexible. For this reason, the prepreg is a sheet-shaped member that requires careful transportation and stacking from the viewpoints of suppressing scratching, suppressing ignition, and suppressing bending and bending.

In the present embodiment, the prepreg will be described as a rectangular sheet-shaped member cut or molded into a predetermined size.

FIG. 1 is a diagram showing an example of the overall configuration of the transport system of the present embodiment. As shown in FIG. 1, the transfer system 100 includes a control device 200 and a separation device 110.

The control device 200 controls the separation and supply of the prepreg by the separation device 110. Details of the function of the control device 200 will be described later.

The separating device 110 separates and conveys the prepreg sheets (sheet-shaped prepregs) stacked in a cut state one by one. The prepreg sheet is an example of the transported object, and a transported object other than the prepreg sheet may be used. The separating device 110 may be any mechanism as long as it supplies a prepreg sheet, and its form is not limited. The separating device 110 may be a mechanism that automatically supplies a sheet-shaped prepreg, or may be a mechanism that cuts a roll-shaped prepreg and supplies the prepreg. Further, the separating device 110 may be a mechanism for manually supplying the prepreg sheet. Further, the separating device 110 may be a combination of at least two of these mechanisms (automatic supply, supply after cutting, and manual supply).

Any treatment can be applied to the treatment of the prepreg supplied by the separating device 110. For example, the prepreg supplied by the separating device 110 may be inspected while being conveyed, and the conveying direction may be branched according to the inspection result.

As shown in FIG. 1, the separating device 110 includes a separating/conveying unit 111, a dust processing unit 112, a blower 113, and a lifting carriage 114. The separation/conveyance unit 111 includes a suction fan 111a and a conveyance belt 111b.

The lifting carriage 114 is a carriage on which a prepreg sheet is placed, and is lifted and lowered according to the amount of the prepreg sheet. The suction fan 111a is a means for adsorbing the uppermost prepreg sheet. The dust processing unit 112 is a unit that draws in and stores dust of the sheet material scattered by the blower 113 when the prepreg sheet is supplied. The dust processing unit 112 may include a replaceable filter that filters out dust. The separation/conveyance unit 111 adsorbs the prepreg sheet to the conveyance belt 111b by the suction force of the suction fan 111a, and sequentially conveys the adsorbed prepreg sheet to a subsequent apparatus (inspection conveyance apparatus or the like).

FIG. 2 is an explanatory diagram showing a hardware configuration example of the control device 200 according to the present embodiment. The control device according to the present embodiment communicates with a control device such as a CPU (Central Processing Unit) 51 and a storage device such as a ROM (Read Only Memory) 52 and a RAM (Random Access Memory) 53 by connecting to a network. The communication I/F 54, the display 55, the bar code reader 56, and the bus 61 that connects the respective units are provided. The control device 200 can be composed of, for example, an ordinary computer.

FIG. 3 is a perspective view schematically showing a part of the inside of the separation device 110. As shown in FIG. 3, the separation device 110 includes a mounting table 131, a front fence 132, an end fence 133, a side air unit 134, a suction conveyance unit 135, and a front air unit 136.

As shown in FIG. 3, a plurality of side air units 134, suction conveyance units 135, and front air units 136 are provided. The number of each unit is not limited to that shown in FIG. Further, any one or all of the side air unit 134, the suction conveyance unit 135, and the front air unit 136 may be provided.

Each unit may be movably installed so that the arrangement of the plurality of units can be changed according to the attribute of the prepreg. For example, it may be possible to change the number of units to be used among the plurality of units, change the position of the units to be used, or the like according to the size of the prepreg. The position of the unit may be changed manually by the user or by a drive mechanism controlled by the control device 200 or the like.

FIG. 4 is a diagram showing an example of arrangement of units. FIG. 4 is a schematic diagram when the separation device 110 is observed from above. As shown in FIG. 4, each unit may be movable, for example, in a direction orthogonal to the supply direction of the prepreg. The suction conveyance unit 135 and the side air unit 134 may be movable in parallel with the supply direction of the prepreg.

Returning to FIG. In the following, description may be given using the coordinate system shown by the X axis, Y axis, and Z axis in FIG. The X axis, the Y axis, and the Z axis are orthogonal to each other. The X axis is the longitudinal axis of the separator 110. The Y axis is an axis in the width direction of the separation device 110. The Z axis is an axis in the height direction of the separation device 110.

The mounting table 131 has a plurality of transfer rollers 131a. The sheet S is placed on the plurality of transfer rollers 131a. The separating device 110 conveys the uppermost sheet S1 of the sheet bundle placed on the placing table 131 in the conveying direction D. The conveyance direction D is a direction in which the separation device 110 conveys a sheet, and is along the X axis. The transport direction D may be a direction intersecting the X axis.

The front fence 132 is arranged so as to be adjacent (contact) to an end portion (front end) in the transport direction D of the sheet bundle placed on the placing table 131. The front fence 132 positions the front end of the sheet bundle.

The end fence 133 is arranged so as to be adjacent (contact) to an end portion (rear end) of the sheet bundle placed on the placing table 131 in the direction opposite to the transport direction D. In other words, the end fence 133 is located on the upstream side in the transport direction D with respect to the sheet bundle arranged on the mounting table 131. The end fence 133 restricts the movement of the sheet bundle to the upstream side in the transport direction D, and positions the rear end of the sheet bundle.

The side air unit 134 injects air that is a gas (hereinafter, also referred to as air) toward the placed sheet. The air jetted from the side air unit 134 is used, for example, for floating the sheet placed on the placing table 131 and separating a part of the plurality of sheets held by the suction conveyance unit 135. The side air unit 134 may be configured integrally with a side fence for restricting the position of the prepreg in the width direction (Y axis direction).

The arrangement position of the side air unit 134 may be changeable in the width direction of the sheet bundle. The position of the end fence 133 may be changeable in the length direction of the sheet bundle (the direction along the X axis). The positions of the end fence 133 and the side air unit 134 are changed according to the size of the sheet bundle, for example.

The suction transport unit 135 is a unit for sucking and transporting the floating prepreg. The suction transport unit 135 includes, for example, a suction air unit (for example, the suction fan 111a in FIG. 1), a negative pressure air chamber, and a transport belt (for example, the transport belt 111b in FIG. 1). The suction air unit injects air for sucking the uppermost sheet of the sheet bundle. The conveyor belt is, for example, an endless belt member having a large number of suction holes communicating with the negative pressure air chamber. The negative pressure air chamber is sucked by the air jetted by the suction air unit to maintain a negative pressure state, and sucks the prepreg on the uppermost surface by the suction hole of the conveyor belt. The prepreg is transported in the transport direction D by rotating the transport belt while the prepreg is sucked. The configuration of the suction transport unit 135 is not limited to this, and may be any configuration as long as the prepreg can be sucked and transported.

In the present embodiment, an example of a holding member that sucks and holds and separates with a negative pressure by air suction is shown, but not limited to air as long as the prepreg can be held, electrostatic suction and the like are also included. ..

The front air unit 136 faces the front end of the sheet bundle placed on the placing table 131. In other words, the front air unit 136 is provided on the downstream side in the transport direction D with respect to the mounting table 131. The front air unit 136 is supplied with air pressurized from the outside and stored therein, and ejects the air toward the sheet bundle.

The air (air that is a gas) also includes air that has been destaticized, and other gases that are used to float the sheets and separate them one by one. Particularly in a prepreg containing carbon fibers, since the prepregs in the stacked state are in close contact with each other due to the action of static electricity and it is difficult to separate them easily, the front air unit 136 may blow the discharged air to the stacked sheet bundle. ..

The front air unit 136 blows air toward the front end of the sheet bundle to lift at least one sheet from the sheet bundle. If the air to be blown out is warm air, a dehumidifying effect is added to the sheets, and the plurality of sheets can be separated more effectively.

The front air unit 136 can stop the injection of air. For example, the front air unit 136 stops the injection of air by closing the opening (nozzle) through which the air is injected. The front air unit 136 may stop the air injection by another method.

The front air unit 136 blows air toward the front end surface of the sheet bundle arranged on the mounting table 131, so that at least one sheet including the uppermost sheet is floated to the height of the suction conveyance unit 135.

The negative pressure air chamber of the suction conveyance unit 135 is brought into a negative pressure state by operating the suction air unit as the sheet floats. Therefore, the uppermost sheet is sucked by the suction conveyance unit 135. In other words, the suction conveyance unit 135 holds the uppermost sheet floated by the front air unit 136.

Other sheets may be in close contact with the uppermost sheet held by the suction conveyance unit 135. The side air unit 134 injects air to separate the sheet held by the suction conveyance unit 135 from other sheets.

In the present embodiment, an example of a separating device including a levitation unit for levitation of a material to be conveyed by jetting air and a holding member for adsorbing and holding with a negative pressure by air suction to separate the material is shown. A separation device for separating the material to be transported is provided with a levitation holding member that also functions as a levitation unit that holds and floats the material to be transported by moving the holding member in the stacking direction of the material to be transported.

The suction transport unit 135 transports the held sheet to a target transport destination. The conveyance direction D is a direction in which the suction conveyance unit 135 conveys the sheet S.

Next, a functional configuration example of the control device 200 and the separation device 110 will be described. FIG. 5 is a block diagram showing an example of functional configurations of the control device 200 and the separation device 110.

As shown in FIG. 5, the separation device 110 includes a floating part 101 (floating means), a holding member 102, and a control part 103.

The floating portion 101 floats the loaded transported objects. The floating portion 101 corresponds to at least one of the front air unit 136 and the side air unit 134 in FIG. 3, for example.

The holding member 102 holds and separates the lifted transported object. The holding member 102 corresponds to, for example, the suction conveyance unit 135 in FIG.

The control unit 103 controls the entire processing of the separation device 110. For example, the control unit 103 controls the floating portion 101 and the holding member 102 to operate according to the setting from the control device 200.

Next, the configuration of the control device 200 will be described. The control device 200 includes a reading unit 221, a display unit 222, a storage unit 223, an acquisition unit 201, a determination unit 202, a setting unit 203, a display control unit 204, an execution control unit 205, and a storage control unit. And 206.

The reading unit 221 reads information from the transported object. For example, the reading unit 221 reads the sheet information from a barcode in which the sheet information of the prepreg is encoded. The coded sheet information may be printed on, for example, a recording medium carried along with a bundle of prepregs mounted on the mounting table 131. The reading unit 221 corresponds to, for example, the barcode reader 56 in FIG. The sheet information is information about the prepreg, and includes, for example, identification information (sheet No) for identifying the prepreg and attribute information. The sheet information is not limited to this and may be any information as long as at least the attribute information can be specified. For example, the attribute information itself may be the sheet information. If the sheet number and the attribute information have a one-to-one correspondence, the attribute information may not be included, and the information including the sheet number may be used as the sheet information.

The method of reading information is not limited to the method using a barcode. For example, a code according to another method such as a QR code (registered trademark) may be used. The information printed on the prepreg without encoding may be acquired by character recognition or the like. Further, the reading unit 221 (barcode reader 56) may be provided in a device other than the control device 200 (for example, the separation device 110) and configured to receive information from this device.

The display unit 222 displays information and corresponds to the display 55 in FIG. 2, for example.

The storage unit 223 stores information used for various processes. For example, the storage unit 223 stores registration information in which the sheet number, the attribute information, and the setting information are associated with each other. The setting information is information indicating the transport condition of the separating device 110 when transporting the prepreg of the corresponding sheet No.

FIG. 6 is a diagram showing an example of a data structure of registration information. As shown in FIG. 6, the registration information includes a sheet number, a product name, a size, a thickness, a separation floating condition, and a suction conveyance condition. The product name, size, and thickness are examples of attribute information. The separation floating condition and the suction conveyance condition are examples of setting information.

The separation floating condition indicates the operating condition of the floating part 101. For example, the separation levitation condition represents the flow rate of air ejected from the levitation unit 101 (front air unit 136 and the like). The suction conveyance condition indicates the operation condition of the holding member 102. For example, the suction conveyance condition represents the flow rate of air ejected from the holding member 102 (suction conveyance unit 135 or the like). The separation floating condition and the suction conveyance condition may be represented by, for example, a ratio to the maximum flow rate. FIG. 6 shows an example of the flow rate when the maximum flow rate is 100.

The setting information is not limited to the example of FIG. 6, and may be any information as long as it is information that determines the operation of the separation device 110. The storage unit 223 can be configured by any commonly used storage medium such as an HDD (Hard Disk Drive), an optical disk, a memory card, and a RAM.

Returning to FIG. 5, the acquisition unit 201 acquires job information. The job information is information indicating a job that is a unit for transporting the transported object, and includes attribute information of the transported object transported by the job. For example, the process of transporting a bundle of prepregs mounted on the mounting table 131 can be one job. As described above, the sheet information is acquired from the recording medium or the like carried along with the bundle of prepregs, and includes the attribute information of the bundle of prepregs. Therefore, such sheet information can be used as job information. In the description below, sheet information is used as job information.

For example, the acquisition unit 201 acquires the sheet information read by the reading unit 221 as the job information. Since the sheet information includes the attribute information, acquiring the sheet information is equivalent to acquiring the attribute information. The acquisition method of the sheet information (attribute information) is not limited to this. For example, the acquisition unit 201 may acquire the sheet information input by the user using an input device such as a keyboard. Further, the job information of one or more jobs processed by the transport system 100 may be received (obtained) from an external server device that manages jobs to be executed. The job information to be acquired may be job information of jobs processed on the same day or may be job information of jobs processed on different days.

The determining unit 202 determines the execution order of the jobs indicated by the plurality of pieces of job information, based on each piece of attribute information included in the sheet information. The method of determining the execution order will be described later. Further, the determining unit 202 determines attribute information corresponding to the acquired attribute information among the attribute information included in the registration information. For example, the determination unit 202 determines registered attribute information that matches the acquired attribute information. The registered attribute information is the attribute information included in the registration information stored in the storage unit 223.

The setting unit 203 sets the operating condition of the separation device 110. For example, the setting unit 203 sets the floating portion 101 and the holding member 102 so as to operate according to the conditions determined according to the determined attribute information. The setting method may be any method. For example, the setting unit 203 notifies the control unit 103 of the separation device 110 of the separation floating condition and the suction conveyance condition associated with the determined attribute information. The control unit 103 operates the floating portion 101 and the holding member 102 according to the notified conditions.

The display control unit 204 controls the display of various information on the display unit 222.

The execution control unit 205 controls the supply process of the transported object by the separation device 110. For example, the execution control unit 205 instructs the separation device 110 to execute the jobs in the determined execution order.

The storage control unit 206 controls writing of information to and reading of information from a storage medium such as the storage unit 223.

Next, the order determination process performed by the control device 200 according to the present embodiment configured as described above will be described with reference to FIG. 7. FIG. 7 is a flowchart showing an example of the order determination process in this embodiment.

The acquisition unit 201 acquires job information (sheet information) (step S101). For example, the acquisition unit 201 acquires sheet information by reading a barcode using the reading unit 221 or the like. The acquisition unit 201 may sequentially store the acquired sheet information in a storage device such as the storage unit 223. The acquisition unit 201 may acquire a plurality of pieces of sheet information collectively or individually from a server device or the like.

The determining unit 202 determines the execution order of the jobs corresponding to the acquired plurality of pieces of job information (step S102). The execution control unit 205 controls the carrying process by the separating apparatus 110 so as to execute the jobs according to the determined execution order (step S103). The order determination process may be executed at any timing before the job is executed.

Next, details of the method of determining the execution order will be described. The determination unit 202 determines the job execution order in consideration of the following conditions.
(A1) Reduce the number of cleaning steps (or time) associated with a change in product name (type). (A2) Reduce the number (or time) of unit placement replacement steps associated with a change in the size of the transported object.

As described above, the cleaning process is performed in order to prevent dust generated from another prepreg made of a different material from being mixed. Therefore, the condition (A1) can be translated into a condition that a plurality of jobs that carry the same type of transported object are continuously executed.

The above condition is an example, and any condition may be used as long as it can be determined based on the attribute information. The execution order may be determined using only one of the above conditions. When a plurality of conditions are used, the priority order of each condition may be set, and the execution order may be determined by applying the conditions according to the priority order. For example, if the cleaning process takes longer than the unit arrangement replacement process, the determination unit 202 first determines the same product name so that the number of cleaning processes (or time) is minimized according to the condition (A1). Determine the execution order so that the jobs are continuous. Further, the determining unit 202 replaces the jobs in the jobs having the same product name so that the number (or time) of the replacement processes of the unit arrangement is minimized.

Here, an example of the arrangement of the units will be described. FIG. 8 is a diagram showing an example of correspondence between sizes and arrangements. The sheet length L represents the length of the prepreg. The sheet width W represents the width of the prepreg. As shown in FIG. 8, for each combination of the range of the sheet length L and the range of the sheet width W, the number of each unit and the information for identifying the arrangement (unit arrangement) are associated with each other.

For example, a prepreg having a sheet length L of 300 and a sheet width W of 300 is associated with the unit arrangement A. In the unit arrangement A, the numbers of the suction conveyance unit 135, the side air units 134, and the front air units 136 are 1, 2, and 1, respectively.

9 to 14 are diagrams showing specific examples of arrangement of each unit. 9 to 14 are examples of arrangements corresponding to the unit arrangements A, B, C, D, E, and F shown in FIG. 8, respectively. As shown in each drawing, the number and arrangement of each unit are changed according to the size of the prepreg 504. The shaded units in each figure represent the units to be operated. It should be noted that the sheet length/sheet width range, the number of units, the arrangement of units, and the like described in FIGS. 8 to 14 are merely examples, and the present invention is not limited thereto.

In the examples of FIGS. 9 to 14, for example, it takes time to switch the arrangement between the unit arrangements A, B, E, and F and the unit arrangements C and D. That is, the downtime of the carrying process becomes large. Therefore, the determining unit 202 may determine the job execution order so that the number of replacement steps between arrangements that causes such a large downtime becomes small.

FIG. 15 is a diagram for explaining a specific example of the method of determining the job execution order. The upper part of FIG. 15 shows an example of the execution order of jobs before replacement. The lower part of FIG. 15 shows an example of the execution order of jobs after replacement. Since the sheet No. is information for identifying a bundle of prepregs, it can be interpreted as information for identifying a job.

Before the replacement, four cleaning steps are required each time the product name changes, and four unit replacement steps between the arrangements that cause a large downtime are required. The determination unit 202 changes the job execution order so that the number of such processes is reduced.

First, the determination unit 202 changes the execution order so that jobs having the same product name are continuously executed so that the number of cleaning processes is reduced. For example, the determining unit 202 changes the execution order so that the job of sheet No. [004] is executed after the job of sheet No. “001” whose product name is “AAA”. Further, the determining unit 202 changes the execution order so that the jobs of the sheet numbers “005” and “006” are executed after the job of the sheet number “002” whose product name is “BBB”.

Next, the determination unit 202 replaces the execution order in the jobs having the same product name so that the number of unit arrangement replacement steps is reduced. When the job with the product name “BBB” is executed in the order of the sheet numbers “002”, “005”, and “006”, the replacement process of the unit arrangement with a large downtime is required between the jobs. For this reason, the determination unit 202 changes the execution order of the jobs of the sheet numbers “005” and “006” so that the unit arrangement changing process can be performed only once. The lower part of FIG. 15 represents the execution order after the replacement in this way.

As described above, in the present embodiment, the control device performs a plurality of processes based on the attribute information of the transported object processed in each of the plurality of jobs so that the effects of the processes other than the transportation process such as the cleaning process are reduced. Determine the job execution order. Thereby, the transported object can be transported more efficiently.

The program executed by the apparatus of this embodiment is provided by being pre-installed in a ROM or the like.

The program executed by the apparatus according to the present embodiment is a file in an installable format or an executable format, and can be read by a computer such as a CD-ROM, a flexible disk (FD), a CD-R, a DVD (Digital Versatile Disk). It may be configured to be recorded in a different recording medium and provided as a computer program product.

Further, the program executed by the apparatus of the present embodiment may be stored in a computer connected to a network such as the Internet and provided by being downloaded via the network. Further, the program executed by the device of this embodiment may be provided or distributed via a network such as the Internet.

The program executed by the apparatus of the present embodiment has a module configuration including the above-mentioned units, and as actual hardware, the above-mentioned units are mainly executed by the CPU (processor) reading the program from the ROM and executing the program. It is loaded on the storage device, and each unit is generated on the main storage device.
