DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rolling roller molding machine capable of automatically replacing a trowel, so-called roller and / or gypsum mold, and a gypsum mold exchanging apparatus used in the rolling roller molding machine.

[0002]

2. Description of the Related Art In a conventional rolling roller molding machine, a raw material placed on a gypsum mold on a shutter shaft is pressed by a roller attached to an upper rotating support shaft, and is rolled into a gypsum mold by the rotating action of both. Plates and bowls are formed. Rollers and gypsum molds have to be replaced due to the type of porcelain to be molded and wear due to rotation, and in recent years of high-mix low-volume production, rollers and gypsum molds may be replaced many times a day.

[0003]

However, since the rollers of the rolling roller molding machine are usually attached to the support shaft of the roller head located above the base frame by bolts, the rollers are removed while supporting the rollers from below. It required a lot of work and a lot of time and effort. Also, the rollers after use are hot and dangerous because they are heated, and the unused rollers and gypsum molds are heavy, so they are limited to replacement work by men, and in some cases work by two people It was necessary, and the work of moving to and from the storage location was heavy labor.

[0004]

SUMMARY OF THE INVENTION In order to solve such problems, the present invention enables automatic replacement of rollers and gypsum molds, simplifies the work of exchanging rollers and gypsum molds, and shortens the exchange time. The first configuration of the rolling roller forming machine is intended to automate a ceramic production line.
A roller arbitrarily identified from a roller station in which a plurality of rollers are made to stand by is transported by a roller traverser and mounted on a lowered support shaft of a roller head moved from a press forming position to a roller replacing position, and a predetermined press forming. This is a rolling roller forming machine having a function of automatically replacing any roller by removing an unnecessary roller from the roller head after returning to the roller station via the roller traverser. This not only enables the roller to be automatically replaced when the rolled roller forming machine is used as a stand-alone type, but also enables the roll-to-roll line to be converted into an automated line from the supply of clay to the forming, drying, and removal to the next process. Incorporation is also possible, and desirably, as a second configuration, the pressing position of the roller head is adjusted by pressing the material set on the gypsum mold against the work by pressing the material set on the gypsum mold into the gypsum mold feeding section for placing the ceramic material on the gypsum mold. Of the endless circulation path in which a forming section for forming, a drying section for drying the work while rotating the work, and an unloading section for taking out the dried work to the next process and sending the gypsum mold to the bed material supply section are set. After being provided so as to be located in the molding section,
The roller to be automatically replaced is mounted on a pallet that is movable between the roller station and the roller traverser, and the pallet moves when the roller head moves from a pressing position to a roller replacement position. A roller is provided so that it can enter the guide rails provided on the base frame, and the roller at the roller exchange position is engaged with the rotated roller support shaft, so that the roller is positioned by a rolling roller forming machine. is there.

[0005] Further, the drive member for moving the pallet by the roller traverser is not particularly limited,
As a third configuration, the roller traverser is fixed to an endless circulation path installed between the roller station and the base frame at the roller exchange position, and the start and stop of the endless circulation path is controlled to control the endless circulation path. A roll roller forming machine that controls the conveyance of the roller traverser and that controls the getting on and off of the pallet at the roller station and the roller replacement position by providing the roller traverser with an extrudable member that allows the pallet to be movable so as to extend and contract. .

[0006] Next, as a gypsum mold paired with a roller, as a fourth configuration, a gypsum mold sequentially taken in and out from one or more mold stock units arbitrarily accommodating a plurality of gypsum molds in a vertical direction is described. Replacement of a gypsum mold used in a rolling roller molding machine including a mold transfer conveyor that moves to an arbitrary storage position, and a mold transfer that holds a gypsum mold at the storage position and moves the gypsum mold to a take-out position next to the mold transfer conveyor. It is intended to provide a device, even if it is a single type rolling roller forming machine, even if it is an automatic type rolling roller forming machine that is unmanned from the supply of the clay to the removal of the molded product, any suitable for the roller Gypsum mold can be supplied automatically. In particular, as a fifth configuration, the mold transfer includes a base frame erected above the accommodation position on the mold transfer conveyor and a take-out position next to the mold transfer conveyor, a traveling platform that moves the base frame, A sliding table that slides a guide member that is vertically movably attached from the traveling platform, and that has a hanging claw that holds a gypsum-type flange from below,
By providing a telescopic member that brakes the slide table along the guide member, the distance between the claw portions is larger than the diameter of the gypsum mold, and all the claw portions hold the gypsum-type flange portion. By controlling the range of the holding distance that can be achieved, the held gypsum mold can be pulled upward and moved to the accommodating position and the unloading position of the mold conveying conveyor. In addition, the shape of the claw portion is not limited as long as it can hold the plaster-shaped flange portion.However, by making the disk shape rotatably attached, the contact area with the gypsum mold becomes large, it is difficult to come off, and the nail is mistakenly made with the gypsum mold. Even if the claws come into contact, the impact is likely to be dispersed in the rotational force. In addition, it is possible to control the expansion and contraction members by connecting them to the paired slides, but it is also possible to connect the expansion and contraction members to one slide and to link the slides with each other with a link member. As a result, the number of driving members for the expansion and contraction members is reduced, and the weight and size of the device can be reduced. Further, if the gypsum mold is replaced, the paired rollers must also be replaced at the same time. As a sixth configuration, a roller arbitrarily identified from a roller station in which a plurality of rollers are on standby is transported by a roller traverser. And while being mounted on the lowered support shaft of the roller head that has moved from the roll forming position to the roller exchange position, unnecessary rollers that have finished the predetermined press forming are removed from the roller head and transferred to the roller station via the roller traverser. By returning, equipped with a rolling roller forming machine equipped with a function that can be automatically changed to any roller, the press forming position of the roller head is set on a gypsum mold with a clay feeding section for placing ceramic material on a gypsum mold A forming section for pressing the formed material into the work, A drying section for drying while rotating, and a carry-out section for taking out the dried work to the next step and sending a gypsum mold to the bed material supply section so as to be located in the forming section in the endless circulation path set. In addition to this, the take-out position beside the mold transfer conveyor is provided between the carry-out section and the bed material supply section, and is automatically replaced with a gypsum mold suitable for a roller to be automatically replaced at the take-out position of the endless circulation path. A gypsum mold exchange device used in a rolling roller molding machine is desirable. This makes it possible to automatically replace the rolling roller forming machine with a set of rollers and a gypsum mold.

By removing the unnecessary roller after the predetermined press molding from the roller head, transporting it through the roller traverser and returning it to the roller station, it has a function that can be automatically replaced with any roller, so it can be used for hot rollers after use The safety can be improved without contact, and the work of moving the unused heavy roller to the storage location can be reduced in labor and the ceramic production line can be automated. Further, by controlling the start and stop of the endless circulation path to which the roller traverser is fixed, the transport control of the roller traverser can be easily performed, so that the cost can be reduced and the maintenance is easy. In addition, by providing the roller traverser with a pallet extruding member so as to be extendable and retractable and automatically controlling the entry of the pallet, the cost can be reduced as compared with the case where the movement control device is individually provided on the pallet.

Next, with regard to the gypsum mold used as a pair with the roller, a mold transport conveyor for moving the gypsum mold taken in and out of the mold stock unit accommodating a plurality of gypsum molds from the take-out position to the accommodation position. A gypsum mold exchange device for use in a rolling roller molding machine having a mold transfer that holds a gypsum mold at the storage position and moves the gypsum mold to a take-out position next to the mold conveyance conveyor. Even if it is a mold rolling roller molding machine, it can save labor by not lifting a heavy gypsum mold by manual power, and even if it is an automatic mold roller molding machine that is unmanned from supply of clay to removal of molded products, its roller Any suitable gypsum mold can be supplied automatically. In particular, the mold transfer includes a base frame provided above a storage position on the mold transfer conveyor and a take-out position next to the mold transfer conveyor, a traveling platform for moving the base frame, and a vertically movable platform. By sliding a guide member attached to the slide base and hanging a claw that holds a gypsum-shaped flange from below, and a telescopic member that brakes the slide base along the guide member, The distance between the claws is controlled within a range between an opening distance that is larger than the diameter of the gypsum mold and a holding distance at which all claws can hold the gypsum mold flange, and pull up the held gypsum mold, It can be moved to the storage position and the take-out position of the mold transport conveyor. In other words, if the roller is replaced, the paired gypsum mold must also be replaced at the same time. Provided so as to be located in the molding section of the circulation path, and a take-out position beside the mold transport conveyor is provided between the carry-out section and the bed material supply section, and a gypsum mold suitable for an automatically exchanged roller is provided. Since this is a gypsum mold exchanging device that is automatically exchanged at the take-out position of the endless circulation path, it can be automatically exchanged with a rolling roller molding machine by a set of rollers and a gypsum mold. In this way, it is possible to cope with a case where the frequency of replacing rollers and gypsum molds is increased due to high-mix low-volume production, and if a set of rollers and gypsum molds necessary for 24-hour production is prepared, automatic molding can be performed. The machine can be made FA and the automatic molding machine can be operated continuously for 24 hours.
