Description

  The present invention relates to a production line system for ceramic moldings provided with a drying line. More specifically, the present invention relates to a production line system for ceramic moldings in which a molding process and a white background conveyance process are linked to a drying process.

  Conventionally, as a general production line system of this type, a system having the following configuration as shown in FIG. 5 is known. That is, a drying furnace 112 is provided in the circulation path 116 of the drying carriage 114, and the drying carriage 114 in which drying pallets P on which ceramic products are placed are stacked in multiple stages can run freely on the circulation path 116 in one direction. Is provided. Further, the pallet unloader 162, the pallet transfer conveyor 164, and the pallet loader 166 are sequentially attached to the circulation path 116 of the drying cart 114 from the outlet side to the inlet side of the drying furnace 112, whereby the drying line 110 is configured. . The drying line 110 is provided with a white background transfer machine 150 beside the pallet unloader 162, and a dough transfer machine 140 is provided beside the pallet loader 166, and the forming line 120 is provided in the dough transfer machine 140. On the other hand, a white background transfer line 150 is connected to the white background transfer machine 150, so that a production line system 101 for ceramics molded products is configured.

  Accordingly, the drying pallet P is circulated and conveyed in advance from the pallet unloader 162 side to the dough transfer machine 140 side by the pallet conveyer 164, and the dough B formed by the forming line 120 is used for drying on the pallet conveyer 164. The material is transferred to the pallet P via the fabric transfer device 140. Next, the drying pallet P on which the dough B is placed is transferred via the pallet loading machine 166 to the drying carriage 114 that is waiting in advance on the pallet loading machine 166 side, and the drying carriage 114 circulates in the circulation path 116. By running, the dough B is transferred to the drying furnace 112 and dried. The dough B is dried by passing through the drying furnace 112 to become a white background C, and the drying carriage 114 on which the white background C is placed on the drying pallet P is carried out of the drying furnace 112.

  The pallet unloader 162 lowers the drying pallet P on which the white background C is placed from the drying cart 114 to the pallet transport conveyor 164, while the drying pallet P disappears and the drying cart 114 that has become empty travels through the circulation path 116. Returning to the loader 166 side which is the original position, it is prepared for the loading of the next drying pallet P on which the dough B is placed. On the other hand, the white background C of the drying pallet P lowered to the pallet transfer conveyor 164 is transferred to the white background transfer line 130 via the white background transfer machine 150 and transferred to the glazing process or the like. On the other hand, the empty drying pallet P is circulated through the pallet transfer conveyor 164 to the original position of the dough transfer machine 140, and is prepared for transfer of the next dough B supplied from the forming line 120. .

  As described above, a series of manufacturing line systems is constructed in which the dough B formed by the forming line 120 is dried in the drying furnace 112, and the dried white background C is transported to the next glazing and baking process through the white background transport line 130. Is done.

  However, the conventional production line system 101 as described above has a problem that the system becomes large and the use space of the site is reduced because the occupied space is large in a limited site. At the same time, there was a problem of large capital investment.

  In addition, in order to manufacture tiles, bricks, etc., which are clay products of various shapes, it is necessary to change the mold of the molding line for each product, and it takes a lot of man-hours and time to change the molding line. . For this reason, lot production for each product has occurred, and it has not been possible to sufficiently meet the recent demand for quick delivery. In particular, the specially shaped tiles called “work tiles” are small quantities of products that are indispensable as roof tiles, although the number of units used per house is small. Conventionally, they have been dealt with by using inventory. However, in recent years, there has been a demand for further cost reduction, and there has been a demand for the construction of a production line system capable of reducing inventory and responding to short delivery times through automation.

  The present invention has been made in view of the above circumstances, and provides a fully automatic, space-saving, and cost-saving manufacturing line system for ceramic moldings that can respond to short delivery times through mixed production of ceramic moldings. Is an issue.

  The production line system for ceramic moldings according to the present invention comprises a circulation path through which a drying cart in which drying pallets for placing ceramic moldings are stacked in multiple stages circulates in one direction freely through a drying furnace. The drying line that makes the ceramic molding dough placed on the pallet pass through the drying furnace to make a white background, the molding line that forms the ceramic molding dough, and the white background conveyance line that conveys the dried white background to the next process And a dough transfer machine for transferring the dough from the molding line to the drying pallet, and a white background transfer machine for transferring the white background placed on the drying pallet after leaving the furnace to the white background conveyor, The dough transfer machine and the white background transfer machine are arm-type articulated robots.

  The production line system for ceramic moldings according to the present invention has the above-described configuration, and the dough transfer machine and the white background transfer machine are arm-type articulated robots, so that the drying is stacked on the drying carriage. The molded product on the dry pallet can be transferred without developing the pallet into a single layer on the pallet conveyor. In other words, the white background is transferred from each drying pallet in the stacked state discharged from the drying furnace onto the conveyor of the white background conveyance line, and all the empty drying pallets in the stacked state after the transfer of all the white backgrounds are transferred from the molding line. Molded material can be transferred. Accordingly, the pallet unloader 162, the pallet transfer conveyor 164, and the pallet loader 166 shown in FIG. 5 are not necessary, and the drying line 110 can be simplified. As a result, the entire production line system can be saved in space and the equipment cost can be reduced.

  Further, in the production line system for ceramic moldings according to the present invention, a plurality of molding lines and a plurality of white background conveying lines are arranged around a transfer machine that is an arm-type articulated robot. By arranging multiple molding lines and multiple white background conveyance lines, it becomes possible to mix and produce various types of ceramic moldings with different shapes, shortening the lead time of production and responding to short delivery times, as required Accordingly, it is possible to produce a variety of molded products as a set. In the production line system for ceramic molded articles of the present invention, it is desirable that the plurality of molding lines be arranged radially with the dough transfer machine as the center. By arranging the molding lines radially, the radius of rotation of the robot arm can be reduced, and space for work such as mold exchange and maintenance can be secured around the molding machine in a small space.

  In the production line system for ceramic moldings according to the present invention, it is desirable that the drying carriage is provided with an identification marking means for the molding placed on the drying pallet loaded on the carriage. An identification mark such as a barcode or IC chip is provided at a specific position of the carriage, and the identification information is detected by a barcode reader or the like at a predetermined position in the carriage circulation path. By controlling the selection of the dough and the operation of the molding line, it is possible to fully and smoothly carry out mixed production of molded products in a fully automated manner.

  A preferred embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 is a schematic plan view of a production line system for ceramic moldings according to an embodiment of the present invention. FIG. 2 is a schematic side view for explaining the relationship between the dough transfer machine and the forming line in FIG. FIG. 3 is a schematic front view for explaining the relationship between the cart on the circulation path and the fabric transfer machine. In addition, as a ceramic molding in this specification, a clay tile, a brick, a tile, etc. can be illustrated.

  The production line system 1 for ceramics moldings of the present invention includes a drying line 10, a molding line 20, and a white background conveyance line 30.

  The drying line 10 can freely run a drying furnace 12 that dries the dough of the ceramics molded product to make a white background, and a carriage 14 (hereinafter also referred to simply as a carriage) loaded with a drying pallet P through the drying furnace 12. And a circulation path 16 that circulates in one direction (the arrow direction in FIG. 1). The circulation path 16 is, for example, a pair of rails laid on the floor surface. In the circulation path 16, movement of a puller, a pusher, or the like that moves the carriage 14 before and after the white loading / unloading position U and the cloth loading position L. Means 18 (18a to 18d in FIG. 1) is arranged, and the carriage 14 can be moved one by one as desired.

  The molding line 20 includes a plurality of molding lines 20a to 20d that are different for each molded product, and the molding lines 20a to 20d are arranged radially with a dough transfer machine 40 described later as a center. Each of the molding lines 20a to 20d has substantially the same configuration. For example, the molding line 20a includes an extrusion molding machine 22a, a cutting machine 24a, a press molding machine 26a, an alignment conveyor 28a, and the like continuously connected in series. The press-molded dough is arranged on the aligning conveyor 28a toward the dough transfer machine 40.

  Moreover, the white background conveyance line 30 is comprised by several conveyance lines 30a-30d different for every molded object, and conveys the white background carried out from the drying furnace to the glazing process which applies the glaze which is the next process. The white background conveyance lines 30a to 30d have substantially the same configuration. For example, the white background conveyance line 30a includes a turntable 32a that converts the direction of the white background transferred from the drying line 10 and a white background that has undergone a direction change. Is conveyed in parallel to the next process along the drying line 10.

  In the vicinity of the dough loading position L, a dough transfer machine 40 is erected to transfer the formed dough B to the empty pallet P on the carriage 14. The fabric transfer machine 40 is an articulated robot including an arm 42, and a suction gripper 44 that grips the fabric B is detachably attached to the tip of the arm 42.

  On the other hand, a white background transfer machine 50 for transferring the dried white background C from the pallet P on the carriage 14 to the white background transport line 30 is provided in the vicinity of the white background loading / unloading position U. The white background transfer machine 50 is an articulated robot having the same arm 42 as the dough transfer machine 40, and a suction gripper 44 that holds the white background B is detachably attached to the tip of the arm 42.

  Each of the drying pallet P, the alignment conveyor 28 and the white background conveyor 34 is provided with a predetermined receiving mold M for supporting the molded product, so that the flat molded product can be stably supported.

  The operation of the production line system 1 for ceramic molded articles configured as described above is as follows.

  At a dough loading position L on the circulation path 16 of the drying line 10, a carriage 14 on which empty drying pallets P are stacked in multiple stages is waiting. The formed dough B is aligned on the alignment conveyor 28 of each forming line 20.

  First, the fabric B1 of the molding line 20a is transferred to a carriage 14a on which empty drying pallets P are stacked in multiple stages. The fabric transfer device 40 lowers the suction gripping tool 44 attached to the arm 42 along the arc Z in FIG. 2 and abuts and grips the fabric B1 waiting in a flat state on the alignment conveyor 28a. By rotating to the vicinity of the carriage 14a along a predetermined rotation locus and moving the arm 42 forward so as to be inserted between the pallets P stacked in multiple stages as shown in FIG. 3, the pallet P is moved to a predetermined position. The fabric B1 is placed (in FIG. 1, three fabrics B1 are transferred simultaneously). The pallet P is provided with a receiving mold M1 corresponding to the back surface shape of the fabric B1. When the fabric transfer machine 40 releases the suction force of the suction gripper 44 and places the fabric B1 on the receiving mold M1 at a predetermined position of the pallet P, the arm 42 is placed between the pallets P loaded in multiple stages. Then, the sheet is pulled out along the predetermined rotation trajectory to turn onto the alignment conveyor 28a, and comes into contact with and grips the next fabric B1 waiting at the end point of the alignment conveyor 28a. By repeating the above operation, the fabric B1 is transferred to all the pallets P loaded on the carriage 14a.

  The carriage 14a that has completed the transfer and is fully loaded with the dough B1 is moved on the circulation path 16 by the moving means 18d and carried into the drying furnace 12. The dough B1 is dried while being transported in the drying furnace 12 from the carry-in side 12a to the carry-out side 12b, and becomes a white background C1 and is carried out from the carry-out side 12b.

  Subsequently, the carriage 14a on which the white background C1 is placed on the drying pallet P is moved to the white background unloading position U by the moving means 18a. At the white background unloading position U, the white background transfer machine 50 sucks and holds the white background C1 on the drying pallet P with the suction gripping tool 44 attached to the arm 42 and transfers it to the white background conveyor 30a (in FIG. 1, 3). A single white background C1 is transferred at the same time). The white background conveyer 30a rotates the transferred white background C1 by 90 degrees on the turntable 32a and then sequentially moves the white background C1 to the conveyer 34a, and the conveyer 34a conveys to the next step, such as a glazing process. When the white background transfer machine 50 repeats these operations to transfer the white background C1 on all the dry pallets loaded on the carriage 14a onto the white background conveyer 30a, that is, when all the dry pallets P are empty. The moving means 18b and the moving means 18c cooperate to move the carriage 14a to the cloth loading position L which is the original position.

  As described above, in the ceramic molding production line system of the present invention, the white background C1 can be unloaded without unfolding the drying pallets P loaded in multiple stages on the carriage 14a in a single layer. The resulting pallet P may be moved to the dough loading position L in a multi-tiered state.

  The above is a series of operations until the dough B1 molded in the molding line 20a is dried to become a white background C1 and conveyed to the glazing process in the white background conveyance line 30a in the production line system for ceramic moldings of the present invention. This series of operations is the same for the fabrics B2, B3, and B4 molded by the molding lines 20b to 20d, and the white background C2, C3, and C4 are glazed by the white background conveying lines 30b, 30c, and 30d, respectively. It is conveyed to the subsequent process.

  In FIG. 1, the forming line 20 and the white background conveying line 30 are each described as four lines. However, in the production line system of the present invention, these are not limited to four lines, and the number of lines can be set as desired. May be increased or decreased. In the above description, the operation of the carriage 14a has been described. Needless to say, many carriages 14 are arranged on the circulation path 16 in addition to the carriage 14a.

  The fabric transfer machine 40 detects a formed body that can be loaded on the cart 14 in advance by using an identification mark such as a barcode or an IC chip attached to each drying cart 14, and the fabric to be transferred based on the information. B can be selected, and the suction gripper 44 can be detachably exchanged for one corresponding to the fabric B to be transferred. Further, the white background transfer machine 50 detects the type and shape of the white background C loaded in the cart 14 in advance by using an identification mark such as a barcode or an IC chip attached to the cart 14 that has been carried out. The suction gripper 44 can be detachably exchanged for the one corresponding to the white background C to be transferred, and can be transferred to the corresponding white background conveyance line 30. In addition, it is preferable that predetermined information can be identified and detected with respect to the molded product for each carriage, such as the type and shape classification of the molded product, the number of transfer to the pallet, the placement method and the alignment order, or the process management.

  By providing such an identification mark, different mixed production of the molded product to be dried for each carriage can be performed fully automatically. For example, as roof tiles for a single house, a roof tile that covers a flat surface (for example, (A) in FIG. 4), sleeve tiles that are laid on the outer edge of the roof (the same (I)), and tento tiles (the same (U)) ) And roof tiles (the same (d)) laid on the ridgeline of the roof, by sequentially drying only the required number of each fabric B1 to B4, A set of roof tiles for one building can be produced. According to this production method, the production lead time can be greatly shortened and the inventory can be reduced as compared with the case where the tiles of each shape are separately produced in lots. Further, as compared with the conventional production line system 101, the pallet unloader 162, the pallet transfer conveyor 164, and the pallet loader 166 are not necessary, so that the drying line 110 can be simplified. As a result, it is possible to achieve a space saving of the entire production line system and a significant reduction in equipment costs.

  In addition, this invention is not limited to said embodiment, It can change in the range which does not deviate from the main point of this invention. For example, in the above embodiment, the molded product to be mounted for each carriage is changed. However, by showing an identification mark for each pallet, a molded product having a different shape can be mounted on one carriage and dried simultaneously. it can. This is particularly effective for the unusually shaped tiles that have a small amount of use, because the required number may be satisfied by several pallets.

  In the above embodiment, a plurality of forming lines are arranged radially around the dough transfer machine, but it goes without saying that a plurality of lines may be arranged in parallel with the drying furnace 112.

  The production line system for ceramic moldings of the present invention is suitable for mixed production in which many types of ceramic moldings having different shapes are mixed and dried. In particular, it is useful as a production line system for roof tiles including accessory tiles and odd-shaped bricks.
