  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The following embodiment is an example embodying the present invention, and is not intended to limit the technical scope of the present invention.

  FIG. 1 is an external view schematically showing an example of a transport system according to the present invention. FIG. 1 shows an example in which each device included in the transport system according to the present invention is arranged in a straight line, and the process proceeds from the right side to the left side in FIG. The conveyance system illustrated in FIG. 1 is a system for conveying a plurality of formed sign plates P and performing various processes up to packing. The transportation target of the transportation system is various registration plates P such as an automobile registration number mark (automobile number plate), a block display board, a road sign, and various other signs. Here, the automobile registration number mark is used as the sign plate P. An example will be described.

  The marking plate P such as an automobile registration number mark is formed by press-molding notation contents such as predetermined characters and figures on a rectangular plate obtained by cutting a metal plate such as a color aluminum plate into a predetermined size, and processing such as coloring. It is formed by doing. Unevenness is formed on the surface of the plate P through the press molding process. Moreover, since the sign board P used as an automobile registration number mark is attached to the front and back of the vehicle, it is handled as a set of two sheets having the same notation content. Therefore, a plurality of sets are packed after being packaged in units of two sheets. Moreover, the order based on notation contents, such as the number currently described, is determined, and the automobile registration number mark is formed according to the order, and is packed according to the order. Packing in accordance with the order means that when packed in a packing box and packed in a box, it is stacked from the upper layer to the lower layer so as to be arranged in the order based on the display contents.

  The arrangement and process of each device in the transport system according to the present invention will be described. The transport system includes various devices such as a plate placing device 1, a first inspection device 2, a superimposing device 3, a packaging device 4, a heating device 5, a applying device 6, a second inspection device 7, a plate loading device 8, and the like. A transport apparatus 9 is provided for transporting the label P between these various apparatuses and transporting it to the packing process.

  The transport device 9 includes a roller conveyor in which cylindrical rollers are arranged in parallel, a drive unit that rotationally drives all or some of the rollers, and the like.

  The sign plate placing device 1 is a device for placing the sign plates P one by one in a predetermined order at a predetermined placement position of the transport device 9. In addition, since the sign board P is formed so as to form a set of two sheets as described above, for example, a series designation number composed of 1 to 4 digits that is one of the written contents is an upper layer. Are placed in the order of “10-10”, “10-10”, “10-11”, “10-11”, “10-12”,. The predetermined placement position as the placement location is an area provided at the end of the conveyance source of the roller conveyor included in the conveyance device 9, and the conveyance device 9 is a sign plate P placed at the placement position. Is conveyed to the first inspection apparatus 2.

  The first inspection apparatus 2 is an apparatus that inspects the content written on the plate P with unevenness by a processing method such as image processing, and performs inspections such as consistency inspection and continuous conveyance inspection. The consistency inspection is an inspection for determining whether or not the written contents of the label P conveyed one by one match the recorded contents recorded in advance in recording means (not shown) such as various memories and server devices. It is. The continuous conveyance inspection is an inspection for determining whether or not the sign plates P having the same notation contents are successively conveyed two by two. Then, the sign plate P inspected by the inspection device is further transported to the superimposing device 3 by the transport device 9.

  The superimposing device 3 is a device that superimposes the transported sign plates P every predetermined number of sheets. In the case of the automobile registration number mark, since it is a set of two sheets, the superimposing device 3 performs an operation of stacking two sheets of the sign plate P having the same display contents being conveyed. In the above-described example of the serial designation number, the two sign plates P labeled “10-10” that are subsequently conveyed are overlapped by the superimposing device 3. Then, the label P superimposed by the superimposing device 3 is further transported to the packaging device 4 by the transport device 9.

  The packaging device 4 is a device that wraps the marking plates P that are stacked in pairs. The packaging device 4 wraps the two display plates P having the same display contents conveyed in a stacked state with a packaging material such as a bag or sheet formed of a transparent material such as polyethylene. Then, the marking plates P packaged in a set of two sheets by the packaging device 4 are further sent to the heating device 5.

  The heating device 5 is a device for welding by heating the packaging material that wraps the sign plate P sent as a set of two sheets. For example, when the heating device 5 is packaged with a bag-shaped packaging material, the heating device 5 is heated by overlapping the insertion holes for inserting the label P, and when the packaging material is packaged with a sheet-shaped packaging material, Heating is performed on the packaging material by heating the overlapped seams. Then, the sign plate P on which the packaging material is welded by the heating device 5 is further transported to the applying device 6 by the transport device 9.

  The assigning device 6 is a device that assigns an identification mark based on the contents written on the sign plate P to the sign plate P that has been transported in a state of being packaged in a pair of two sheets. As the identification mark, for example, a sticker displaying a coded code such as a one-dimensional bar code or a two-dimensional bar code indicating the written contents is used. Affixed to the bag. Then, the sign plate P to which the identification mark is provided by the applying device 6 is further transported to the second inspection device 7 by the transport device 9.

  The second inspection device 7 is a device for inspecting the appearance of the sign plate P that is wrapped in a set of two sheets and attached with an identification mark, and the coded code shown in the assigned identification mark and the sign plate P Perform inspections such as comparison with the contents described in. Then, the sign plate P inspected by the second inspection device 7 is further transported by the transport device 9 to the sign plate stacking device 8.

  The plate loading device 8 is a device for loading the plate P which is packaged in a set of two sheets and given an identification mark. Since the packaged label plates P are transported one by one by the transport device 9, the label plate stacking device 8 sets a plurality of sets of label plates P in a predetermined manner so that the transported label plates P can be packed. Stack in order. And the signboard P which piled up the predetermined number of sets is conveyed to a packing process.

  The packing process is a process in which the loaded label P is packed manually and automatically or semi-automatically into a packing box such as a cardboard box, and the transportation to the packing process is loaded at the place where packing is performed. It shows that the sign plate P is conveyed. The label P packed in the packing process is appropriately shipped in packing units.

  Next, the reference sign stacking device 8 will be further described in detail. In the following drawings, some configurations are shown through outlines so that the arrangement of each configuration is clear. FIG. 2 is a front view schematically showing an example of the sign board loading device 8 according to the present invention. The signboard stacking device 8 holds a first platen 80a, a second stacking table 80b, a third stacking table 80c on which a plurality of signboards P conveyed by the conveying device 9 are loaded, and a sign plate P. A first loading mechanism 81a and a second loading mechanism 81b that move to the loading position and stack at the loading position are provided as main components.

  The first loading table 80a, the second loading table 80b, and the third loading table 80c are arranged in the order of the first loading table 80a adjacent to the transfer device 9, the second loading table 80b, and the third loading table 80c. In addition, a transport table 82 for transporting the label P to the packing process is disposed adjacent to the third stacking table 80c. In the following description, when there is no need to classify the individual loading tables (the first loading table 80a, the second loading table 80b, and the third loading table 80c), the loading table 80 is indicated.

  Each loading table 80 (the first loading table 80a, the second loading table 80b, and the third loading table 80c) includes a rectangular parallelepiped loading unit 801 on which the label plate P is loaded and a long support leg that supports the loading unit 801. 803. On the upper surface of the stacking unit 801, a plurality of drive rollers and guide rollers having a cylindrical shape, and a transfer unit 802 such as a belt conveyor using an endless transport belt around which these rollers are wound are disposed. The drive roller is controlled to rotate and stop by a rotation drive unit (not shown). The conveyance belt rotates around each roller in conjunction with the rotation of the driving roller, and conveys the loaded label P to the next step. In addition, if it is a mechanism which transfers the label | marker plate P, you may use transfer parts 802 other than a belt conveyor.

  Each support leg 803 is erected substantially vertically with one end fixed to the lower surface of the stacking unit 801, and an elevating drive unit 804 is provided in the middle so that it can move vertically. It has been. The elevating drive unit can move each support leg 803 up and down, and the stacking unit 801 moves up and down between the upper limit position and the lower limit position by moving the support leg 803 up and down. When the first loading table 80a, the second loading table 80b, and the third loading table 80c are raised to the upper limit position, each loading table 80 (the first loading table 80a, the second loading table 80b, the third loading table 80c). The upper surface of the stacking unit 801, the upper surface of the transfer device 9, and the upper surface of the transfer table 82 to be transferred to the packing process have substantially the same height. When the first loading table 80a, the second loading table 80b, and the third loading table 80c are respectively lowered to the lower limit position, each loading table 80 (first loading table 80a, second loading table 80b, third loading table 80c). The upper surface of the stacking unit 801 is substantially the same height.

  The first stacking mechanism 81a and the second stacking mechanism 81b are mechanisms that move the label plate P to the next stacking position and stack it. In the following description, when there is no need to separate the individual stacking mechanisms (the first stacking mechanism 81a and the second stacking mechanism 81b), the stacking mechanism 81 is indicated.

  The stacking mechanism 81 (the first stacking mechanism 81a and the second stacking mechanism 81b) includes a holding unit 811 that holds the label P. The holding part 811 has, for example, a suction cup that can be sucked under reduced pressure. The suction part abuts on the upper surface of the reference plate P, and the suction plate P is sucked by reducing the pressure inside the suction cup, thereby holding the reference plate P. be able to. The holding part 811 can release the adsorbed label P by releasing the pressure reduction in the suction cup.

  The holding portion 811 is suspended from a rail 812 disposed above so as to be able to be moved up and down, and is moved up and down by an elevating drive unit (not shown). The rail 812 is disposed along the conveying direction of the sign plate P, and the holding portion 811 includes a wheel (not shown) that engages with the rail 812, and the rail 812 is rotated by driving the wheel. It can move in the transport direction.

  The holding unit 811 of the first stacking mechanism 81a is movable between the transport device 9 and the first stacking table 80a, and stacks the label P transported by the transport device 9 on the first stacking table 80a. Go. The holding portion 811 of the second stacking mechanism 81b is movable between the second stacking table 80b and the third stacking table 80c, and the label P loaded on the second stacking table 80b is moved to the third stacking table 80c. Stack up.

  Next, an operation related to the sign plate loading device 8 will be described. FIG. 3A, FIG. 3B, FIG. 3C, FIG. 3D, FIG. 3E, and FIG. 3F are explanatory views schematically showing an example of the operation of the sign plate loading device 8 according to the present invention. These drawings show a process of stacking a plurality of label plates transported by the transport device 9 and transporting them to the packing process in order of time series from FIG. 3A to FIG. 3F. It should be noted that the sign plates that are conveyed are in a state of being packaged in pairs, and in a predetermined order, such as “10-10”, “10-11”, “10-12”,... It is conveyed in a proper order. In the following description of the operation, for convenience, a series of four-digit serial designation numbers written on the label P are indicated by a combination of “P” and a lower case letter, and are packaged in pairs. The description will be made assuming that the sign plate P is conveyed in the order of the sign plate Pa, the sign plate Pb, the sign plate Pc,..., The sign plate Px, the sign plate Py, and the sign plate Pz.

  FIG. 3A shows the initial positions of the first stacking table 80a, the second stacking table 80b, and the third stacking table 80c, and the sign plate conveyed by the conveying device 9. As shown in FIG. 3A, the initial position of the first stacking table 80a is the upper limit position, the initial position of the second stacking table 80b is the lower limit position, and the initial position of the third stacking table 80c is the upper limit position. In addition, the holding unit 811 of the first stacking mechanism 81a is positioned on the transport device 9 side, and the holding unit 811 of the second stacking mechanism 81b is positioned on the second stacking table 80b side. In addition, the standard plates are conveyed from the upstream side in a predetermined order by the conveyance device 9, and the first set of standard plates Pa has arrived at the end position of the conveyance device 9. From the state illustrated in FIG. 3A, the signboard stacking device 8 sucks and moves the signboard Pa that has been conveyed by the first stacking mechanism 81a, as indicated by the arrow, and moves it on the first stacking table 80a. Placed on.

  FIG. 3B shows a state in which the first sign plate Pa is placed on the first loading table 80a. The sign plates have been sequentially conveyed in a predetermined order. In the example shown in FIG. 3B, the second sign plate Pb is approaching the end of the conveying device 9 as indicated by an arrow. When the sign plate Pb arrives at the end of the transport device 9, the sign plate Pb is held by the first stacking mechanism 81a and placed on the sign plate Pa on the first stacking table 80a.

  FIG. 3C shows a state in which a plurality of sets of sign plates are loaded on the first loading table 80a. Since the first stacking mechanism 81a is stacked from the bottom in the order in which the standard plates are conveyed, the standard plates Pa, standard plates Pb, standard plates Pc,... The plates are stacked in the order of the plate Px, the label plate Py, and the label plate Pz. It should be noted that the signboards loaded on the first loading table 80a are placed so that the placement positions thereof are staggered, that is, the placement positions of the top and bottom neighboring signboards are different from each other, skipping one by one. The placed plates P are placed so as to be shifted so that the placement positions of the plates P are the same.

  FIG. 4 schematically shows an example of the loading state of a plurality of marking plates on the first loading table 80a according to the marking plate loading apparatus 8 of the present invention. FIG. 4A is a plan view, and FIG. 4B is a front view. When loading on the first loading table 80a, the label plates are stacked so as to be staggered by shifting the mounting position one by one. The direction of shifting is the long side direction of the rectangular label, and is also the transport direction connecting the transport device 9 and the first stacking table 80a. By changing the stopping direction on the first stacking base 80a side of the holding unit 811 that moves along the rail 812 of the first stacking mechanism 81a by changing the shifting direction as the transport direction, the alternate stacking illustrated in FIG. Can be realized. Therefore, the number of parts can be suppressed and control can be facilitated, so that an increase in cost can be suppressed.

  Moreover, the sign plate loading apparatus 8 handles the sign plate packed by the previous process with heating. When the welding parts of the packaging material that have just been welded are stacked, the packaging materials may adhere to each other. Therefore, the signboard stacking device 8 can prevent the welding portions of the packaging material from overlapping and adhering to each other by stacking the mounting positions one by one and stacking them alternately.

  In addition, since unevenness is formed as the written contents on the surface of each standard plate, when a plurality of standard plates are stacked at the same position, the upper level standard plate is more likely to be inclined. For example, as illustrated in FIG. 4 (a), a label with only the last two digits such as “..− 34” is loaded with “..− 35” and “..− 36”. The lower right corner, where no numbers are shown, tends to be lower. Therefore, it is possible to expect an effect of suppressing the inclination of the upper level plate by shifting the placement position. By suppressing the inclination of the upper level plate and placing it substantially horizontally, when the holding unit 811 is sucked by the suction cup, the level plate is kept almost horizontal, so that the suction reliability is high. It is possible to improve and stabilize the process.

  Returning to FIG. 3C, after a plurality of sets of label plates are shifted and stacked on the first stacking table 80a, the drive roller of the stacking unit 801 is driven to rotate on the first stacking table 80a as indicated by the arrow. A plurality of sets of loaded signs are transferred to the second loading table 80b while maintaining the loaded state.

  FIG. 3D shows a state in which the loaded label is transferred to the second loading table 80b. From the state shown in FIG. 3D, as indicated by an arrow, a plurality of sets of signboards loaded on the second loading table 80b are stacked again on the third loading table 80c, that is, reloaded. The signboard to be reloaded is restacked so that the long side and the short side are aligned. Reloading to the third loading table 80c is performed from the upper layer of the plurality of sets of loading plates loaded on the second loading table 80b. The board is loaded on the top layer. In other words, on the third stacking table 80c, the sign plate Pz, the sign plate Py, the sign plate Px,..., The sign plate Pc, the sign plate Pb, and the sign plate Pa are loaded in this order from the lower layer to the upper layer. When reloading from the second loading platform 80b to the third loading platform 80c, the height of the uppermost layer of the marking plate loaded on the second loading platform 80b and the level of the marking plate loaded on the third loading table 80c. In order to make the height of the uppermost layer approximately the same, it is preferable to sequentially raise the stacking unit 801 of the second stacking table 80b and to lower the stacking unit 801 of the third stacking table 80c.

  FIG. 3E shows a state in which a plurality of sets of signboards are reloaded on the third stacking table 80c. After reloading a plurality of sets of labels on the third loading table 80c, the upper surface of the loading unit 801 of the third loading table 80c is substantially the same as the height of the upper surface of the conveyance table 82 for carrying to the packing process, as indicated by the arrows. The stacking unit 801 is raised to the upper limit position so as to be the same level, and further, the driving roller of the stacking unit 801 is driven to rotate, so that a plurality of sets of signboards stacked on the third stacking table 80c can be loaded. It is transferred to the transport table 82 side while maintaining the state.

  FIG. 3F shows a state in which a plurality of sets of repositioned label plates have been transferred to the transport table 82. After the transfer to the transport table 82, as shown by the arrows, the plurality of sets of sign plates are transported to the packing process while maintaining the reloaded state. In the packing process, for example, a worker in charge manually packs a plurality of sets of re-loaded labels in a packing box while maintaining the loading order. When the worker in charge manually packs the packing box, since the slight inclination does not affect the work, there is no need to shift the sign plate when reloading as shown in FIGS. 3E and 3F. Efficient packing work can be done by aligning the long and short sides of the plate.

  In addition, since the labeled plates to be packed are stacked in the order of the labeled plate Pa, the labeled plate Pb, the labeled plate Pc, ..., the labeled plate Px, the labeled plate Py, and the labeled plate Pz from the upper layer to the lower layer. When taking out the signboard from the packaging box, the worker in charge can take out the signboard in a predetermined order by taking it out from the upper layer.

  3A to 3F, the first loading table 80a and the second loading table 80b are configured as different loading tables. With this configuration, the process of reloading from the second stacking base 80b to the third stacking base 80c and the process of stacking from the transfer device 9 onto the first stacking base 80a can be performed at the same time. Become. As a result, it is possible to prevent the process related to loading, which takes a relatively long time, from becoming rate-determining, and to improve the productivity as a whole. Also, the transport direction from the first stacking table 80a and the transport direction from the second stacking table 80b can be different directions. In this case, it is possible to increase the degree of freedom of layout when there is a restriction on the installation space of the transport system according to the present invention. Such an effect can also be obtained by changing the transport direction from the third stacking table 80c or the transport direction by the transport device 9.

  The above embodiment only discloses a part of the myriad examples of the present invention, and can be appropriately designed in consideration of various factors such as purpose, application, specification, setting, and the like.

  For example, the marking plate P has been shown to be loaded while being shifted in the long side direction, which is the moving direction, but the present invention is not limited thereto, and may be loaded while being shifted in the short side direction. You may make it stack | stack by shifting in both the long side direction and a short side direction. In addition, the number of units in the case of shifting can be designed as appropriate, such as shifting by two sets instead of shifting one set at a time.

  Furthermore, in the above-described embodiment, the form using the first loading table 80a, the second loading table 80b, and the third loading table 80c has been described. However, the present invention is not limited to this, and the loaded reference plate P is loaded. Only the first loading table 80a and the second loading table 80b for reloading the label P loaded on the first loading table 80a may be used. Furthermore, the second loading table 80b and the conveyance table 82 may be used. And may be shared.

  In addition, the sign plate P to be processed is not limited to the automobile registration number mark, but can be various sign boards P such as a block display plate, a road sign, and various other signs. Further, in the case of such a kind of label P, it is not always necessary to wrap two sheets as a set. For example, three or more sheets may be packaged or one sheet may be packaged. When packaging one by one, the sheets are loaded while being shifted one by one.
