For reference, in the manufacturing die replacing apparatus according to the present invention, the operation controls of each part are operated and controlled by sensing the sensors installed at the respective specific parts. A detailed description will be omitted as an electronic control technique.

An operation of the seat cushion mold changing apparatus according to the present invention will be described as follows.

First, the mold carrier 10 arranged in a rotating manner by the moving table 110 disposed on the circulating rail 3 of the track 1 is driven by the circulating rail 3 operated by the driving means 2 The mold carrier is circulated continuously.

The molding of the seat cushion is performed during each circulation process through the production mold (not shown) mounted in the upper cassette section 10-1 of the mold carrier 10. [

For reference, the cassette unit 10-1 is configured such that the upper side is rotated from a certain point and can be operated in the home position again, and the seat cushion is manufactured according to the manufacturing mold according to the manufacturing mold.

Before the production quantity of the seat cushion is manufactured, another manufacturing mold is appropriately replaced before the production quantity is adjusted. Thus, the mold carrier is appropriately selected without stopping the operation of the automatic production line according to the manufacture of the seat cushion. And the mold carrier in which the new manufacturing mold is replaced is re-introduced into the circulating rail side, so that the above-described sheet forming process can be continuously performed.

1 is a schematic view showing a state where circulation is carried out while holding a moving table 110 and a mold carrier 10 installed on a circulating rail 3 on a track 1, In the state in which the replacement of the mold is required, the mold carrier in which the sheet molding is manufactured is selected and discharged from the circulating rail to the outside.

As described above, in order to discharge the corresponding mold carrier 10 to the outside, the mold carrier 10 is released from the holding of the mold carrier 10, which is disposed on the circulating rail 3.

When the operating rod of the chucking cylinder 114 provided in the body 111 is retracted, the moving rod 110 is released from the connecting hole of the mold carrier-side connecting plate to naturally separate the mold carrier 10 At this time, the mold carrier 10 moves away from the circulating rail 3 along the moving rail 120, and is moved to the carrier replacing means 140 side.

The guide rollers 12 of the mold carriers are guided to the fixed rails 142 on the side of the base portion 140-1 constituting the carrier replacing means 140 in order to enter the mold carrier 10 toward the carrier replacing means 140 And the drive unit 140-3 of the carrier replacement unit 140 operates according to the detection signal in such a state to advance the rail variable unit 140-2 with respect to the base unit 140-1.

The driving unit 140-3 rotates the rotation plate 148 installed on the rotation output shaft of the speed reducer 147 connected to the driving motor 146 and the driving motor from the base 140-1 side.

The rotation of the rotary plate 148 is rotated by 180 degrees and the link 149 connected to the rotary plate and the rail variable portion 140-2 is rotated by a deviation connected to the rotary plate 148, .

In this state, the variable rails 145 on the rail variable portion 140-2 are aligned with the fixed rails 142 of the base portion 140-1 to guide the guide rollers 12 of the mold carrier 10 So that the traveling direction of the mold carrier 10 spaced apart from the movable base 110 can be switched.

The rail changing part 140-2 in which the guide rollers 12 of the mold carrier 10 are positioned rotates the rotating plate of the driving part 140-3 by 180 degrees so that the rail changing parts 140-2 Is retreated along the guide rail 141 of the base portion 140-1 and at this time another fixed rail 143 fixed to the base portion 140-1 and the variable rail 145 coincide with each other do.

The position of the moving table 110 moving along the circulating rail 3 in such a state is determined by the fact that the portion of the rolling roller 115a on the close contact support table 115 finally pushes the mold carrier 10 onto the carrier guide rail 130 And is moved along the circulating rail 3 in a spaced apart state.

The mold carrier 10 which has been moved from the fixed rail 143 side of the base part 140-1 to the carrier guide rail 130 can discharge the mold carrier to the outside through the carrier transferring means 150, The mold carrier 10, which has been completely taken out of the apparatus, can perform various operations such as replacement of the manufacturing mold of the cassette unit 10-1 or abnormal condition inspection according to the management of the operator.

As shown in Fig. 1, the mold carrier 10 having completed the setting or checking of the manufacturing mold as described above is moved in the direction opposite to the direction in which the mold carrier is discharged, The carrier transporting means 150 installed on one side of the carrier carrier 10 is operated to move the mold carrier 10 through another carrier replacing means 140 located before the entry of the circulating rail along the carrier guide rail, To the circulating rail side.

Here, the movable carrier 110 chucks and circulates the mold carrier entering the circulating rail.

When the mold carrier 10 is moved into the carrier replacing means 140 by the carrier conveying means 150 along the carrier guide rail 130, the base portion 140 of the carrier replacing means 140 -1 are moved along the movable rail 120 through the fixed rail 142, the variable rail 145 and the fixed rail 143 of the base 140-1 by the driving part 140-3 Move it.

That is, the operation of the carrier replacing means 140 when the mold carrier 10 is externally discharged or when it exits from the outside to the circulating rail 3 side is performed in the same manner.

The mold carrier 10 moved as described above naturally moves along the circulating rail 3 while being chucked by the chucking chamber leader 114 of the moving table 110 moving along the circulating rail 3, A molding process is performed.

The carrier moving means 150 pushes the pushing member 151 provided on the conveying conveyor 152 so as to reciprocate the pushing member 10-2 of the cassette unit 10-1, When the mold carrier 10 from which the mold carrier 10 is discharged from the circulating rail 3 or the cassette unit 10-1 of the discharged mold carrier 10 is replaced with the mold for manufacturing and the maintenance and repair of the abnormal part is completed, It is possible to quickly move to the circulating rail 3 and enter it.

Meanwhile, since the mold carrier 10 discharged to the outside of the apparatus of the present invention is capable of pulling out a plurality of mold carriers 10 only in a space allowed by the working space, and can inspect and replace the mold, There is an advantage that the space can be utilized more effectively than when replacing a conventional manufacturing mold, and since a plurality of mold carriers can be handled, it is very advantageous for quick replacement work and maintenance of the mold carrier from the circulating rail.
