 The present invention relates to a loader for a press device and a press device system for carrying in a workpiece and / or carrying out a workpiece from the press device.

Conventionally, for example, in order to manufacture a printed wiring board (PWB), a flexible printed wiring board (FPC), or the like, a plurality of workpieces (such as a resin film. In addition to molded products after processing, are referred to as "products") in one press. The multi-stage press apparatus to process is used. This multi-stage press apparatus has an upper press panel, at least one intermediate press panel, and a lower press panel. The upper and lower press panels each have a press surface of one side on a lower surface or an upper surface, and the intermediate press panel has a press surface of two upper and lower surfaces. Each press panel is arrange | positioned by stacking up and down with the press surface substantially horizontally next to each other. This press apparatus operates as follows. First, the press panels are arranged at intervals from each other in the lamination direction, and the product is placed on the upper press surface of the lower press panel and the intermediate press panel. Subsequently, when the press panels are driven in a direction in which the press panels are adjacent to each other, the upper and lower surfaces of the product eventually come into contact with the opposing press surfaces of the adjacent press panels (that is, the product is fitted into the upper and lower press panels). In addition, when the press panel is driven, a compression load is applied to the product, and the press working of the product is performed. Subsequently, after the press working is completed, the press panels are driven in a direction away from each other so that the product can be taken out from the multi-stage press apparatus.

Moreover, a press apparatus system is comprised by this multi-stage press apparatus and the stacker and loader mentioned later. The stacker temporarily stores the products before and after the press working, and the loader is responsible for conveying the products between the stacker and the multi-stage press apparatus. On the other hand, the product always remains on the transfer plate (carrier plate) during the series of processes by this press device system. That is, a product is stored in a stacker in the state mounted on the conveyance board, conveyed by a loader, and press-processed in a multi-stage press. Even after processing, the product is conveyed by the loader while being placed on the transfer plate and stored in the stacker again.

The stacker is configured to be stored with the same relative positional relationship as when a plurality of products processed in one press are arranged in a multi-stage press apparatus. The stacker has a substantially rectangular parallelepiped housing and a support arm protruding inwardly from an inner wall of the housing. Moreover, the support arm is provided with the click part which protruded upward from the front-end | tip. Each conveyance plate is comprised so that it may be stored in the stacker in the state supported by the some support arm (more specifically, the click part) from below.

The stacker is also connected to a conveying mechanism such as a belt conveyor mechanism. The product before the press working is transported to the stacker from the previous process via this belt conveyor mechanism in a state of being placed on the transfer plate, and then stored in the stacker by a mechanism known in the art. In addition, the press-processed product stored in the stacker is conveyed to the post process through the belt conveyor mechanism while also being placed on the transfer plate.

Next, specific functions of the loader will be described. The loader moves (1) in front of the stacker first, (2) removes the product from the stacker while maintaining the positional relationship between the products at the time of storage, and (3) then moves to the front of the multi-stage press unit in the state of loading the product. Then, the product is transferred onto the lower press panel and the intermediate press panel of the multi-stage press apparatus. In the meantime, the positional relationship between the products during storage in the loader is maintained. In this way, the multi-stage press apparatus is in a state capable of pressing the product. Moreover, when taking out the press-processed product from a multi-stage press apparatus and storing it in a stacker, it implements in the reverse order to the process mentioned above. That is, the loader moves in front of the multi-stage press apparatus, takes out the press-worked product from the multi-stage press apparatus, moves the stacker in front of the stacker with the product loaded therein, and finally stores the product in the stacker. During this time, the relative positional relationship of the product is maintained when the loader takes out the product.

A conventional example of such a loader is disclosed in Japanese Patent Application Laid-Open No. 7-115240 (Japanese Patent Publication). In the configuration described in Japanese Patent Application Laid-open No. Hei 7-115240, the loader includes a plurality of pairs of loader arms, and is configured such that one conveying plate is mounted on a pair of loader arms (loader arm pairs). .

Each of the loader arms is configured to be driven in an up and down direction in conjunction with each other, and the transfer plate above the loader arms can be picked up by moving the loader arms upward. The press of the support arm or press device of the stacker located below the transfer plate by moving the loader so that the loader arm enters the stacker or the press device while the transfer plate is raised on the loader arm, and then lowers the loader arm. The transfer plate can be replaced in half.

The plural pairs of loader arms are arranged side by side in the vertical direction, and by simultaneously lowering the plural pairs of loader arms, a plurality of transfer plates mounted on each loader arm can be placed on the support arm of the press panel or stacker at the same time. . Furthermore, by simultaneously raising a plurality of pairs of loader arms, it is possible to simultaneously lift up a plurality of transfer plates mounted on a support arm of a press panel or stacker.

In the configuration as described in Japanese Patent Application Laid-Open No. 7-115240, it is necessary to send this loader arm into the stacker and the press device when loading or unloading the transfer plate. In a multi-stage press apparatus, the hydraulic cylinder which drives a press board is normally arrange | positioned under a lower press board. Therefore, when a support structure for supporting the loader arm is provided on the tip side of the loader arm (the side close to the stacker or the press device), the support structure itself interferes with the hydraulic cylinder of the press device, and the loader arm is pressed against the press device. Can't import into me Therefore, the supporting structure for supporting the loader arm is provided only at the proximal side of the loader arm (the end of the side farther from the stacker or press device). That is, the loader arm is supported by the cantilever structure.

In addition, in order to support the product and the conveying plate with this loader arm, the length of the loader arm needs to be about the same as the maximum product dimension in the longitudinal direction. When the product is supported by the loader arm having such a length dimension, the bending moment is concentrated at the base end of the loader arm. Also, as described above, the loader arm needs to be raised and lowered. The conventional loader of the structure in which each loader arm has a drive mechanism is provided with the drive mechanism (cylinder mechanism, ball screw mechanism, rack-pinion mechanism, etc.) which drives a loader arm in the up-down direction at the base end side of a loader arm. In this case, the above-described bending moment is concentrated on this drive mechanism, in particular its engaging portion. Therefore, in the conventional configuration, especially when carrying a product having a relatively large weight and / or a relatively long maximum product length, it is necessary to take a large engagement area to sufficiently withstand the bending moment. As a result, there has been a problem that the drive mechanism for driving the loader arm in the vertical direction is enlarged, and the loader and press device systems are enlarged. There is also a conventional apparatus having a configuration in which the loader arm is collectively raised / lowered for each support post supporting the loader arm. In this case, since the weight of a movable part is heavy, it is necessary to use a large drive device, and similarly, there exists a problem that an apparatus system becomes large.

In order to solve the said problem, according to embodiment of this invention, the press apparatus which moves a to-be-processed object between the press apparatus which press-processes a to-be-processed object, and the stacker which stores the to-be-processed object before and / or after press work. A loader for use has a loader arm support and at least one pair of loader arms supported at one end by the loader arm support and extending horizontally, each pair of at least one pair of loader arms having a workpiece to be placed thereon. There is provided a loader for a press apparatus, comprising a pair of plate holders capable of holding a carrier plate, and a pair of lift mechanisms for moving the pair of plate holders in a vertical direction with respect to each pair of loader arms.

2-5, the stacker 100 and the press apparatus 200 are arrange | positioned side by side in the up-down direction in the figure. In addition, the loader 300 is configured to take over the product at the place adjacent to the right side of the stacker 100 and the press apparatus 200 in the drawing. Thus, the loader 300 is movable between the first position (lower position in FIG. 2) adjacent to the stacker 100 and the second position (right upper position in FIG. 3) adjacent to the press apparatus 200 (FIG. 3). Up and down direction).

As shown in Figs. 2 and 3, the loader 300 has loader arms 310 and 320 extending in the left and right directions in the drawing, and a pair of loaders with loader arms 310 and 320 having substantially the same height. The arm pair 301 is constituted. When the loader 300 is in the first position (FIG. 2), it is possible to move the loader arm pair 301 towards the stacker 100. Moving the loader arm pair 301 (FIG. 4) causes the loader arm pair 301 to enter stacker 100. Here, each of the loader arms 310 and 320 constituting the loader arm pair 301 is provided with product receivers 313 and 323 (corresponding to the "plate holder" of the claims) for supporting the product from below. . The loader arm pair 301 enters the stacker 100 to transfer the product disposed in the stacker to the product receivers 313 and 323 or to stack the product supported by the product receivers 313 and 323. It becomes possible to change to (100).

It is also possible to move the loader arm pair 301 towards the press device 200 when the loader 300 is in the second position (FIG. 3). When the loader arm pair 301 is moved (FIG. 5), the loader arm pair 301 enters into the press apparatus 200, and the product supported by the product receivers 313 and 323 is provided with a nibble of the press apparatus 200.

In a series of processes of this embodiment, a product is comprised so that conveyance and press work may be carried out on the carrier plate which is a rectangular metal plate. The stacker 100 has a plurality of resin plate products P arranged side by side in the vertical direction. Each product P is mounted on a carrier plate M each made of metal. As shown in FIG. 4, each of the carrier plates M is supported by the support arms 111 to 114 of the rack 110 at four points. The support arms 111 and 112 extend from the upper side in the figure to support the carrier plate M, and the support arms 113 and 114 extend from the lower side in the figure to support the carrier plate M. FIG. The support arms 111 and 113 are arranged side by side in the vertical direction in the figure. Similarly, support arms 112 and 114 are arranged side by side in the vertical direction in the figure.

7 is a front view of the stacker 100 (viewed from left to right in FIG. 2). As shown in Fig. 7, each of the support arms 111 to 114 is provided in a plurality of sets (three sets in the drawing) side by side in the vertical direction, and on a set of support arms 111 to 114 arranged in the horizontal direction. One carrier plate M is comprised so that it may be raised.

Support arms 111 to 114 are fixed to the apparatus frame of the stacker 106. The carrier plate M on which the product P is placed is carried into the stacker 100 from the left side in FIG. The lifting conveyor 120 which conveys the carrier plate M in the left-right direction (henceforth "the conveyance direction") in FIG. 2 is used for carrying in into the stacker 100 of the product P. FIG. The lifting conveyor 120 is movable in the vertical direction (the direction perpendicular to the ground in FIG. 2). In addition, the lifting conveyor 120 is driven such that the plate mounted thereon can be conveyed from left to right in FIG. These driving of the lifting conveyor 120 is performed by the drive mechanism not shown.

As shown in FIGS. 2, 4, and 7, the dimensions of the lifting conveyor 120 in the up and down direction (hereinafter referred to as "width direction") in FIG. 2 are the widthwise intervals of the support arms 111 and 113, the support arm. It is formed narrower than the width direction space | interval of 112 and 114. FIG. Therefore, the lifting conveyor 120 can move freely up and down without interfering with the support arms 111 to 114.

Next, the procedure to mount the carrier plate M and the product P on the support arms 111-114 of the stacker 100 is demonstrated. 8A to 8D are enlarged views of a portion of the A-A cross section of FIG. 2. On the other hand, as shown in the figure, each of the support arms 112 and 114 has click portions 112h and 114h extending vertically upward. The support arms 111 and 113 also have click portions 111h and 113h having the same shape (see FIG. 2).

8A shows a state before the carrier plate M is conveyed in the stacker 100. As shown in FIG. 8A, the upper surface 122 of the lifting conveyor 120 is at a position higher than the horizontal surface TS1 defined by the upper end of the click portion of the uppermost support arms 111 to 114.

Subsequently, the lifting conveyor 120 is driven such that the upper surface 122 of the lifting conveyor 120 moves forward (direction from left to right in FIG. 2), and the carrier plate M carrying the product P is lifted ( It moves to the area | region (region 121: FIG. 2, FIG. 4) between each support arm 111-114 of 120. As shown in FIG. This state is shown in Fig. 8B. In this state, the bottom surface of the carrier plate M is at a position higher than the above-described horizontal surface TS1 (that is, the surface defined by the upper end of the click portions of the uppermost support arms 111 to 114). Therefore, the carrier plate M and the product P are conveyed in the horizontal direction in the stacker 100, without the carrier plate M and the click parts 111h-114h of a support arm interfering.

The lifting conveyor 120 then descends to the position shown in FIG. 8C. As a result, the upper surface 122 of the lifting conveyor is lower than the horizontal surface TS1, and the carrier plate M is moved above the click portion of the uppermost support arm.

Subsequently, the lifting conveyor 120 is driven so that the upper surface 122 of the lifting conveyor 120 moves forward (ie, moves from left to right in FIG. 2), and the carrier plate M carrying another product P is lifted. It moves to the area | region (region 121; FIG. 2) between each support arm 111-114 of 120. As shown in FIG. This state is shown in Fig. 8D. In this state, the bottom surface of the carrier plate M is at a position higher than the horizontal plane TS2 defined by the top of the click portions of the second support arms 111-114 from above, and the top of the carrier plate is at the top end. It is at a position lower than the horizontal plane BS1 defined by the lower ends of the support arms 111 to 114. Moreover, the dimension in the width direction of the product P is shorter than the width dimension of the gap between the support arms 111 and 113 and the width dimension of the gap between the support arms 112 and 114. Also, the height of the uppermost end of the product P is lower than the horizontal plane TS1 (that is, the position of the bottom surface of the carrier plate M of the upper stage) defined by the upper end of the click portions of the uppermost support arms 111 to 114. Is in. Therefore, the carrier plate M and the product P mounted thereon are conveyed into the stacker 100 without interfering with the click portions 111h to 114h of the support arm and the carrier plate at the upper end.

The steps of FIGS. 8C and 8D are then sequentially performed from the upper stage with respect to all the remaining sets of support arms 111 to 114 (see FIG. 3), respectively, to each set of support arms 111 to 114, respectively. ) And the product P are put up.

In the present embodiment, the stacker 100 or the press device 200 and the loader 300 are configured to take over the carrier plate M on which the product P is loaded. In order to perform this handover, each of the loader arms 310 and 320 is provided with lift mechanisms 314 and 324 which raise / lower the product receivers 313 and 323 relative to the loader arms 310 and 320. Hereinafter, the configuration of the lift mechanisms 314 and 324 will be described with reference to the drawings.

9 is a cross-sectional view (B-B cross-sectional view of FIG. 2) obtained by cutting the loader arm pair 301 in the width direction. 10 is a perspective view of the loader arm 310 of the loader arm pair 301 viewed from the loader arm 320 side. 11 and 12 are side views of the loader arm 310 attached to the lift mechanism 314 and the guide mechanism 315 as viewed from the loader arm 320 side, respectively. In addition, in order to demonstrate the structure of a loader arm pair clearly, the product P on the carrier plate M is abbreviate | omitted in FIG. 9, and the carrier plate M and the product P are abbreviate | omitted in FIGS. . As shown in the figure, the product receivers 313 and 323 are long members having a concave cross-sectional shape, and the inner side surfaces in the width direction of the loader arms 310 and 320 through the lift mechanisms 314 and 324, respectively. Is attached to. Further, in a state in which the carrier plate M is placed on the contact surfaces 313a and 323a, which are bottom surfaces of the cavity of the concave portion, the carrier plate M and the product P placed thereon are placed on the product receiver 313, 323 is supported below.

The lift mechanisms 314 and 324 are cylindrical members fixed by bolts to the widthwise inner side surfaces of the loader arms 310 and 320. Pistons 314a and 324a are provided in the cylinder so as to be slidable. The pistons 314a and 324a are movable in the vertical direction while sliding with the cylinder inner circumference. Moreover, the lift mechanism 314, 324 is equipped with the drive mechanism not shown in figure, and can drive the piston 314a, 324a to an up-down direction. As this drive mechanism, the thing using a hydraulic or pneumatic motor, the thing using a solenoid, etc. can be used. The lower ends of the pistons 314a and 324a are fixed to the upper surfaces of the product receivers 313 and 323, and the product receivers 313 and 323 can be moved in the vertical direction by driving the pistons 314a and 324a.

10 and 12, a pair of guide mechanisms 315 are fixed to the inner side surface of the loader arm 310 in the width direction by bolts. The guide mechanism has a through hole 315b penetrating in the vertical direction, and a guide bar 315a is slidably inserted therein. In addition, the lower end of the guide bar 315a is fixed to the upper surface of the product receiving 313. As the pair of guide bars 315a integrated with the product receiver 313 are guided by the through holes 315b, the movement direction of the product receiver 313 is limited only in the up and down direction. On the other hand, a guide mechanism 325 having a function equivalent to the guide mechanism 315 is provided on the loader arm 320 (see FIG. 2, etc.), and the movement direction of the product receiver 323 is guided by the guide mechanism 325. It is comprised so that it may be limited only to an up-down direction.

The procedure of taking out the carrier plate M and the product P arranged in the stacker 100 by the loader 300 using the lift mechanisms 314 and 324 described above will be described below with reference to FIGS. 4 and 13A to D. FIG. To explain.

As described above, the loader 300 includes loader arms 310 and 320 extending in a direction parallel to the conveying direction of the carrier plate M by the lifting conveyor 120. Further, only one pair of loader arm pairs 301 is shown in the figure, in practice, the loader arm pairs 301 are arranged in pairs at the height of each corresponding set of support arms 111-114, respectively.

As shown, the loader arms 310, 320 are a kind of cantilever whose one end is supported by arm guides 311, 321 extending in the vertical direction (corresponding to "loader arm struts" in the claims). Since the loader 300 is driven so that the loader arms 310 and 320 enter the stacker 100 with the free ends 312 and 322 (see FIG. 1) of the loader arms 310 and 320 leading, the arm guide ( 311 and 321 do not interfere with the stacker 100. Hereinafter, the position of the loader 300 which is most suitable for loading a product from a stacker is defined as a product taking over position (position of the loader 300 of FIG. 4).

Hereinafter, a specific procedure for taking out the carrier plate M and the product P mounted thereon from the stacker 100 using the loader 300 will be described. 13A to 13C are cross-sectional views taken along line A-A of FIG. 13D is a cross-sectional view taken along line B-B in FIG. 2.

FIG. 13A illustrates a state before the loader arms 310 and 320 are inserted into the stacker 100. At this time, the loader 300 is in the first position.

The loader 300 then moves to the product take over position. 13B illustrates a state in which the movement of the loader 300 to the product takeover position is completed. As shown in FIG. 13B, the product receivers 313 and 323 are at a second height at which the abutment surfaces 313a and 323a are slightly lower than both ends in the width direction of the carrier plate M (left and right in the figure). In this embodiment, the width direction both ends of the carrier plate M are bent in a crank form, and the height direction dimension of the space | interval part between the bottom surface of the width direction both ends of the carrier plate M, and support arms 111-114 is large. Is taken. Accordingly, the product receivers 313 and 323 are configured such that the product receiver does not touch the carrier plate M or the support arm when the loader arm is horizontally fed into the stacker.

At this time, the loader arms 310 and 320 are supported below the support roller 115. The support roller 115 is a cylindrical roller supported freely in the axial direction on an axis extending inward in the width direction from the device frame of the stacker 100. The height of the top of the support roller 115 is approximately equal to the height of the bottom of the loader arms 310, 320. Therefore, when the loader arms 310 and 320 advance and retreat in the conveying direction, the support rollers 115 rotate along the movement thereof, support the loader arms so as not to bend, and advance and retract the loader arms 310 and 320 without resistance. It is configured to.

Next, the lift mechanisms 314 and 324 are driven to lift the product receivers 313 and 323 to the first height. When the product receivers 313 and 323 are at the first height, the abutment surfaces 313a and 323a are at a position slightly higher than the upper ends of the support arms 111 to 114. As a result, the carrier plate M rises from the support arms 111-114 like FIG. 13D.

Next, the loader 300 is moved to the first position. FIG. 13D shows a cross section in the width direction of the loader 300 when the movement to the first position of the loader 300 is completed. In FIG. 13C, the carrier plate M is in a state supported only by the loader arms 310, 320. When the loader 300 is moved in the state of FIG. 13C, as shown in FIG. 13D, the carrier plate M is placed on the loader arms 310 and 320 with the carrier plate M (and the product P thereon) mounted thereon. And the product P are taken out of the stacker 100.

As described above, in the present embodiment, when the product P is taken out of the stacker 100, the product receivers 313 and 323 attached to the loader arms 310 and 320 are driven in the vertical direction, and the loader 300 The loader arms 310 and 320 themselves are not driven in the vertical direction. That is, a large bending moment is applied to the fixed ends of the loader arms 310 and 320 (ends on the side of the arm guides 311 and 321 in FIGS. 1 to 5), but the loader arms 310 and 320 do not pass through the movable mechanism. Since it is directly fixed to the arm guides 311 and 321, the loader arm can be firmly supported. Therefore, the loader arms 310 and 320 can maintain the product stably even if the product P is heavy. Moreover, the weight of a movable part becomes much lighter compared with the structure which moves up and down every arm guide. Therefore, it becomes possible to use a small and light movable mechanism with low power, and the whole loader can be reduced in size and light weight.

Subsequently, the carrier plate M and the product P held by the loader 300 are placed on the nirvana (described later) of the press apparatus 200. As shown in FIGS. 2-5, in this embodiment, the stacker 100 and the press apparatus 200 are provided side by side in the width direction (up-down direction in drawing). With the carrier plate M raised on the loader arms 310, 320, the loader 300 is moved from the first position (FIG. 2) to the second position (FIG. 3). As a result, the loader 300 is adjacent to the right side in the drawing of the press apparatus 200. When the loader 300 is moved in the second position toward the press apparatus 200 (direction from right to left in FIG. 3), the loader arms 310 and 320 and the carrier plate M mounted thereon are moved. And product P enters press apparatus 200 (FIG. 5). The position of the loader 300 at this time is defined as a product arrangement position (position of the loader 300 of FIG. 5).

The structure of a press apparatus is demonstrated below. 14 is a front view of the press apparatus 200. As shown in FIG. 2 and FIG. 10, the intermediate nirvana guide mechanism 210 is a guide bar 211 in the form of a footnote extending in two vertical directions (up and down direction of the surface) provided near both ends of the width direction of the nirvana 220. ) And a pair of guide plates 212 arranged side by side in the conveying direction for connecting the two guide bars 211 to secure the rigidity of the intermediate nirvana guide mechanism 210. In the middle of each guide bar 211, the heat receiving block 214 corresponding to each of the intermediate hot plates 223 is fixed. The nirvana guide 223a is formed to protrude in the width direction at both ends in the width direction of the intermediate nirvana, and the nirvana guide 223a is loaded on the nitrile receiving block 214 to provide the intermediate nirvana guide mechanism ( 210 is supported from below.

Moreover, the side which is farthest from the nirvana as one side surface of the bar 211 is being fixed to the inner surface of the side frame 271 of the press apparatus 200. As shown in FIG.

The table surface 251 of the press apparatus is configured to be driven in the vertical direction by the hydraulic cylinder 260. The lower hot plate 222 is fixed to the upper surface of the table surface plate 251. Here, when the hydraulic cylinder 260 is driven to raise the table surface plate 251 and the lower platen plate 222, and the lower platen plate 222 contacts the intermediate plate plate 223 thereon through the product P, The intermediate nirvana 223 is supported below the lower nirvana 222. In this state, when the table surface plate 251 is further raised, the nirvana guide 223a is moved away from the nirvana plate block 214, and the lower nirvana 222 and the intermediate nirvana 223 thereon are integrated to move upward. do. Here, when the lower nirvana 222 and the intermediate nirvana 223 contact the intermediate nirvana on one stage through the product P, the intermediate nirvana 223 is likewise integrated with the lower nirvana 222. Move upwards. This process is repeated to bring the intermediate nirvana 223 of the best stage into contact with the upper nirvana 221 with all intermediate nirvana 223 integral with the lower nirvana 222. In this state, press work of the product P is performed by applying pressure to the product P through the lower hot plate 222. On the other hand, the dimensions and mounting positions of the nirvana guide 223a and the nirvana block 214 in the conveying direction are determined by the nirvana guide 223a of the intermediate nirvana 223 and the nirvana plate block 214 located above it. 251 is configured not to interfere when moving. More specifically, in FIG. 14, in the drawing of the middle nirvana 223 of one stage, the right end of the nirvana guide 223a on the left side corresponds to the nirvana block 214 corresponding to the middle nirvana 223 of the upper stage. It is formed in the left side in the figure rather than the cross section of the left side of the figure. Similarly, the left end of the nirvana guide 223a on the right side of the middle nirvana 223 of any one stage is formed to the right of the right end of the nirvana plate block 214 corresponding to the middle nirvana 223 of the upper stage.

Hereinafter, the procedure to arrange | position the carrier plate M and the product P hold | maintained by the loader 300 to the press apparatus 200 is demonstrated in detail. 15A to C are cross-sectional views taken along line C-C in FIG. 3 of the press apparatus 200, respectively. In addition, although only one carrier plate M and one product P are each described in FIGS. 15A-C, in the installation process of this embodiment demonstrated below, all the carrier plates M hold | maintained by the loader 300 are shown. ) And product P are performed at the same time.

In this embodiment, the carrier plate M supported by the product receivers 313 and 323 of the loader 300 moves to the nirvana by lowering the product receivers 313 and 323 at the third height to the fourth height. Lose. In addition, in this embodiment, 3rd height is the same height as the 1st height of the product take over position in a stacker, and 4th height is comprised so that it may become the same height as the 2nd height of the product take over position in a stacker.

FIG. 15A shows the state where the loader 300 is moved to the product placement position and the loader arms 310, 320, the carrier plate M and the product P are brought into the press apparatus 200. On the other hand, the middle nirvana 223 is shown in the figure, and the same process is performed on the lower nirvana 222. At this time, the bottom surface of the carrier plate M is disposed at a position higher than the top surface of the corresponding intermediate hot plate 223 (or lower hot plate 222).
