  Hereinafter, the best mode for carrying out the present invention will be described.

  The base material shaping | molding apparatus which concerns on this invention comprises the conveying apparatus 2 and the attachment or detachment incidental equipment 3 as shown to FIG.

  The conveying apparatus 2 conveys the base material 1 on a circular track. In the example shown in the drawing, the transport device 2 is configured by providing a circular drive unit 5 having a circular shape in plan view that is driven to rotate horizontally with respect to the base unit 22 above the base unit 22. An appropriate drive mechanism for the rotation drive unit 5 is provided. In the present embodiment, a tooth groove 23 is provided over the entire circumference of the side peripheral surface of the rotation drive unit 5 and, as shown in FIG. An intermeshing gear 24 and a drive motor 25 that rotationally drives the gear 24 are provided. By driving the drive motor 25, the rotational drive unit 5 can be rotationally driven.

  Further, the rotation drive unit 5 can be driven and controlled so as to repeat an operation of being stopped after being rotated by a predetermined amount. In this embodiment, the rotation drive unit 5 is stopped every time the rotation drive unit 5 rotates 1/4. Thus, the drive motor 25 is controlled.

  On the upper surface of the rotation driving unit 5, four transfer tables 4 are provided along the periphery of the rotation driving unit 5 so as to be circumferentially arranged at equal intervals. When the rotation driving unit 5 is driven to rotate, each transfer table 4 is rotated. Moves around the circular orbit. The illustrated conveyance table 4 is formed in a disk shape and is formed so as to be horizontally rotatable with respect to the rotation drive unit 5.

  The rotation driving unit 5 is provided with a control mechanism for controlling the horizontal direction of the conveyance table 4 by controlling the horizontal rotation of the conveyance table 4 with respect to the rotation driving unit 5. For example, in the example shown in FIG. 4, a central gear 26 that rotates integrally with the rotational drive unit 5 is provided at a central position inside the rotational drive unit 5, and the central gear 26 is meshed with the central gear 26 around each central gear 26. A planetary gear 27 that is connected to the transport table 4 and rotates integrally with the transport table 4 is provided. At this time, the gear ratio between the central gear 26 and the planetary gear 27 is set to 1. When the control mechanism is configured in this way, when the rotation drive unit 5 is driven to rotate and the central gear 26 rotates at the same time, the planetary gear 27 rotates once every time the rotation drive unit 5 and the central gear 26 rotate. Apparently, it goes around the central gear 26 without rotating. Thus, when the rotation drive unit 5 is rotationally driven, the transport table 4 apparently does not rotate horizontally but circulates around the orbit, and the tray 10 and the substrate 1 disposed on the transport table 4 are in the horizontal direction. Thus, the orbit is orbited while keeping the direction of.

  The configuration of such a control mechanism is an example. In addition to controlling the horizontal direction of the carriage 4 as described above, the gear ratio between the center gear 26 and the planetary gear 27 is changed, By appropriately interposing another gear between the planetary gear 27 and the like, the direction of the transport table 4 on the orbit can be controlled in various ways. Further, the configuration of the control mechanism is not limited to the above, and it is possible to provide a mechanism for controlling the horizontal direction of the transport table 4 on the circular track by an appropriate mechanism.

Are arranged so as to face toward the planetary gear 27 arranged at a predetermined position. The positioning tool 28 is connected to the drive unit 30 via a connecting bar 29 connected to the back portion of the base portion 28a. The drive unit 30 drives the positioning tool 28 forward and backward between a state where the positioning tool 28 is biased toward the planetary gear 27 side and a state where the positioning tool 28 is pulled toward the opposite side of the planetary gear 27. It is formed by an appropriate piston mechanism or the like.

  Such a positioning tool 28 is arranged in a state of being pulled to the opposite side of the planetary gear 27 by the drive unit 30 while the rotary drive unit 5 is rotationally driven. In the stopped state, the drive unit 30 is controlled to urge the positioning tool 28 toward the planetary gear 27 and to bring the open portion of the positioning tool 28 into contact with the planetary gear 27. At this time, the positioning tool 28 and the planetary gear 27 come into contact with each of the protruding portions 28b on both sides or the protruding portions 28b and the base portion 28a. Therefore, the planetary gear 27 is forcibly disposed at a predetermined position and positioned. Is done. At this time, if the distance between the protrusions 28b is too large, the planetary gear 27 only comes into contact with the base 28a and cannot be positioned. Therefore, the dimension between the protrusions 28b is adjusted so that the planetary gear 27 contacts the protrusions 28b. Is.

  When the planetary gear 27 is positioned by the positioning tool 28 as described above, the “play” between the gears 26 and 27 is performed when the horizontal rotation of the transport table 4 is controlled by the transmission of power between the gears 26 and 27 as described above. Even if a slight displacement occurs in the planetary gear 27 due to the rotation drive unit 5 being stopped, the positioning position of the planetary gear 27, that is, the arrangement position of the carriage 4 is finely adjusted by the positioning tool 28. It is possible to accurately arrange the horizontal direction of the transport table 4 at this time while arranging it at an accurate position.

  Next, while rotating the rotation drive unit 5 by a predetermined amount (1/4 rotation), the positioning member 7 is operated in the same manner as described above to stop the rotation drive unit 5 and finely adjust the stop position. . At this time, the conveyance table 4 after the substrate 1 and the tray 10 are taken out is accurately arranged at the supply position of the tray 10 by the tray supply equipment 9a, and the conveyance table 4 is moved in the horizontal direction by the control mechanism as described above. Is accurately controlled in a predetermined direction.

  Next, by repeatedly performing the above-described operation, the base material 1 is supplied and formed on the circular orbit and supplied to the next process transport equipment 3c.

  The operation as described above is also performed simultaneously on the other transport bases 4 that circulate around the orbit by the rotation driving unit 5, thereby sequentially supplying the tray 10 on each transport base 4, forming the base material 1, The substrate 1 is conveyed to the next process conveyance unit.

  The change of the line layout by the above substrate forming apparatus will be described.

  The case where it is necessary to change the line layout includes, for example, a case where a dimension of the base material 1 to be molded is changed or a design pattern of the base material 1 formed at the time of molding is changed.

  That is, when changing the dimensions of the base material 1, particularly the thickness and the extrusion dimensions at the time of extrusion molding, the line layout of the base material forming equipment 3 a is not changed, so When the position becomes a position different from that before the change, and the arrangement position of the base material 1 is changed at the time of mold forming or the like, thereby causing troubles such that the mold cannot be formed at an accurate position. There is. Moreover, when changing the uneven | corrugated design pattern of the base material 1 formed at the time of shaping | molding, it is necessary to change the upper mold | type 18 in the molding apparatus 3b to another thing, and the uneven | corrugated pattern formed in the base material 1 is changed. When changing to a design having a large unevenness difference and a high design property, it is necessary to change the tray 10 functioning as the lower mold to have a different thickness so that the thickness of the tray 10 is changed. Then, the position of the base material 1 when the base material forming equipment 3a forms the base material 1 and supplies the tray 10 on the transport table 4 becomes a position different from that before the change. Similarly, there may be a problem that it becomes impossible to mold at an accurate position. In particular, when a cement-based molding material that forms a W / O emulsion as described above is used as a molding material for forming the substrate 1, the moldability when forming the substrate 1 by extrusion molding or the like is usually Since it is higher than the cement-based molding material, and it is easy to maintain the shape after molding, it is molded into a base material 1 of various thicknesses and dimensions by extrusion molding or the like, and a deeply concavo-convex design deeply carved by molding into the base material 1 While it becomes possible to add a pattern, the necessity of changing the line layout to cope with such a change in dimensions is particularly high.

  In addition, when the dimensions of the tray 10 and the base material 1 are changed in this way, the next-process transport equipment 3c before the change may not be able to cope with it, and the next process in which the base material 1 after the molding is transported may be different. Sometimes it changes to a thing. For this reason, it may be necessary to change the layout of the next process transfer equipment 3c.

  When the line layout needs to be changed in this way, the base material forming equipment 3a, the mold forming equipment 3b, and the next process transport equipment 3c, which are the attachment / detachment auxiliary equipment 3, are appropriately removed from the transport device 2 and the different structures are provided. It is possible to cope with this by simply connecting the attachment / detachment accessory 3 and the line layout can be easily changed in a short time. At this time, when a new attachment / detachment accessory 3 having the above-described connecting portion 6 is connected to the transfer device 2, the transfer device 2 and the new attachment / removal attachment 3 are connected to each other in the horizontal position and above and below. It can be easily connected in a state where the directional position is regulated, and the tray 10 and the base material 1 are arranged at a predetermined accurate position on the circuit track even after the line layout is changed. It is possible to perform the processing such as the transporting and the like accurately as described above.

  Moreover, also when changing the arrangement position of the conveyance apparatus 2, after removing each attachment / detachment auxiliary equipment 3 from the conveyance apparatus 2, moving these to another position, and connecting them again, the conveyance apparatus 2 is easy. In this case, the line layout can be easily changed in a short time. Further, unlike the case of using a linear and long conveyance line, in the present invention, since the conveyance device 2 that conveys the base material 1 on a circular path is used, the conveyance device 2 is formed compactly, and the conveyance device. 2 can be moved without being divided, labor and time required for division / reassembly can be reduced, and labor required for movement of the transfer device 2 can be reduced.
