Here, the operation of forming the cake cup (12) will be explained.

First, the movable cup (13) is placed in the state shown in FIG.

(2IC).

<21D) is a through hole formed by a convex portion (12E) provided at the center of the lower cup (12B) during preforming.

In this way, to form goo'1': (21>, J,
During press molding, this cake (21) is

This is the fourth part (21B) (
21C), air is not introduced during molding, and therefore, the surface of the disc after it is molded into a disc shape will not have any scratches due to air bubbles.

Next, a press machine for forming a predetermined disk by press-molding the preformed parts formed by the above-mentioned preforming apparatus m (12> at ℃) will be explained with reference to FIG. 2 ([3)].

This press machine (22) can be moved up and down by a hydraulic cylinder (26) installed on a base (2:>), and one end of the upper part of a support frame (27) is set on the base (25). The operation panel (movable arm) (30) is installed on the plate (28) and is slidably supported on the idle boss 1- (29), and the 29) +7) The above work is on one end of the top! The FIlfIFi (30) is mounted opposite to the 4-shoulder 1-board (soil frame) (31) and covered. A lower mold (24) for molding a required disk is attached at a predetermined interval to the upper side of the L old operating plate (30). Similarly, one side of the upper plate (31) facing the M motion fiA (30) is provided with the lower mold (24).
) is installed to form the disk. These upper and lower molds (23)<24) are formed in a C-circular shape corresponding to the outer periphery of the disk, and each has a stamper (not shown) on one side of the outer periphery for forming image information, etc. of the disk. ).

Then, the preformed part (hereinafter referred to as cake) supplied to the lower mold by the stone supply device is shaped into a predetermined shape by the operation (upward movement) of the hydraulic cylinder (26). is press-molded into a disc. In addition, the upper plate (31) is provided with a hinter pin (33) that is inserted into the through hole (21D) in the goo 4 (21>) and serves as a guide for forming the final inner diameter shape by press forming. The mold (case 24) is provided with a hole (34) for accommodating the center pin (33).

In this way, the relatively thick through hole (2
The reason for providing the center pin (33) and the like inserted therein is as follows.

For example, in the case of a J3 video disc, the diameter of the hole in the center of the disc is the same as that of a normal audio disc due to the mechanism of the playback device and the accuracy of the center hole required for the disc white. -It is much more popular than ``-'' and has been adopted.

By the way, when forming a center hole in a video disc, for example, conventionally, a small diameter hole is formed in the same way as the needle for A-D, and a large hole is drilled based on this hole in the next step. Was.

However, according to such conventional methods, there is a limit to the eccentricity of the small hole that is initially formed, and when punching the human hole, the hole is punched based on this small hole, so the eccentricity of the small hole is limited. Furthermore, since deformation, cracking, etc. are added, there is a drawback that the lateral vibration of the disk becomes severe during playback.

Therefore, in order to eliminate the drawbacks of the conventional method, the present invention forms a through hole (21D,) of a predetermined shape in advance when making a cake, and during press molding, a predetermined hole diameter is formed in the through hole (21D). A pin (33) with a predetermined external shape of Iζ to form
is inserted, and then press-molded.

In this way, a pin (33) having a predetermined outer shape, for example, approximately the same diameter as the center hole of a video disc, is inserted into the upper mold (23), and this pin (33) is inserted into the lower mold (1). Since the hole (34) is provided, the process can be simplified compared to the conventional center hole forming force method, and the overall labor can be saved, and there is no need to form a small hole. The dimensional accuracy of the center hole is improved and the variation b in the hole size can be reduced.

A center pin (33) and a hole (34) facing the center pin (33) into which the center pin (33) is inserted are set at predetermined positions in the upper molds (23) and (24). Due to this, the cake (21) is placed on the press I (22),
When the lower mold (23), (24>-L) is transferred to the predetermined position, this center bin (33) I;1: is easily inserted into the through hole (21D) provided in the cake (21). be done.

According to the present invention, the through hole (21) of the cake (21)
D) has a relatively large hole diameter, so there is no need to center bunch the large diameter with a large pressing force during pressing.
Therefore, even if the pressing force during pressing is small, a through hole of a predetermined size can be easily formed. This is an important point when forming a hole in the center of this type of information recording medium.
-.

In other words, the information recording medium is vinyl chloride as described in 1.
Because it is made of carbon-based conductive resin,
Molded +A1'+1 is so hard! ] Therefore, if the center bamboo is pressed with a large pressing force, the impact force will have a considerable effect on the video information portion, etc. Furthermore, if the pressing force is small, it will naturally be advantageous in terms of pin life.

Next, the case (mold) will be explained with reference to FIG. 2(B) and FIGS. 6(Δ) to (E).

Below, using these Figures 6(A) to ([), goo-t (

First, the preformed cake (21) is shown in Figure 16 (B).

) is brought to a predetermined position on the lower case (24). In this way, when the cake (21) is brought to a predetermined position, a switch (not shown) is activated, which activates the cylinder (32), and the center bin (33) moves downward to remove the cake. (21) is inserted into the through hole (21D), and this cake (21) is held and covered in a predetermined position of the lower mold (24). (Fig. 6C) When the cake (21) is held in a predetermined position in this way, a switch (not shown) is activated, and the hydraulic cylinder (26) moves upward to move the cake (21) held in place. 21> is pressed (press molded) at a predetermined pressure. (D in Fig. 6) When press molded at a predetermined pressure for a predetermined time, a disk (D) with information signals etc. recorded in a predetermined portion is formed. However, this disk has a so-called overflow portion and is not in its final external shape.

When the disk with overflow is molded, this disk (D) is held by a gripper, which will be described later, and the center pin (33) moves once to its original position, and
The T molds (24) are lowered and returned to their original positions. (Fig. 6F) As mentioned above, the disk that has been press-formed for a predetermined period of 1.1 at a predetermined pressure is on the right side of the so-called overflow part, so in order to make this the final external shape, borders a part of the overflow (1~
rimming).

However, in the general rimming process, a molded part of a predetermined shape is covered with a cutter to form a desired external shape, but in the case of an information recording medium, the molded part is not molded. The feed is hard, and as mentioned above, audio signals and bidet A signals are recorded at high density from the outer periphery to the inner periphery of the disk on a flat disk. Since the i-rimming is performed on the outer periphery where the video information is recorded, sufficient attention must be paid to the effect of this i-rimming on the video information area.

Therefore, the present invention is directed to J which does not have any influence on BiIA information even in such J~rimingue culm.

The upper and lower cases (molds) (23) (24)
'ATU was solved as follows, and this point will be explained in detail using FIG. 7 (Δ) to (D>).

In addition, in the drawings, the same parts will be explained using the same reference numerals.

First, we will discuss how precision is necessary in information recording media.

As mentioned above, the information recording medium is composed of a plurality of pitch rows recorded on a flat disk surface.
．． The data is reproduced in a spiral manner from the outer circumference to the inner circumference at a track pitch of 35 μm. Pitch 1~ is the same as pitch 1.3
A width of 5 μm and a depth of 0.3 to 0.4 νm have been recorded. Therefore, between each 1 and the rack, there is a guard band J
There are no burrs, and the surface of the disk can be used without waste. 1-Ranking (ffi No. 1 to column is 0.6-0.7u in width centered on the border of 1-rack and I-rack)
15. m 1 at the horizontal synchronization signal position at a depth of 0.05 μm.
74 Kt-1z numbering is recorded over the information signal. The information signal pin 1~column includes video and
The main bit string recorded by frequency modulating fft three different signals with one carrier wave, each having two frequency-modulated channels. is an auxiliary pit row for enabling the reproduction t1 to correctly trace the information pits 1 to 1 on a disk whose surface is flat and has no mechanical guide grooves.

The 4~71- ringing signal is composed of three six-wavelength frequencies, and two of these signals determine the playback #.
1 is always in the correct position, and one rotation of the disk can be detected by the third signal.

In the NTSC system, the disk rotates at 900 revolutions per minute, and thus rotates at 15 revolutions per second. Four fields (two frames) are recorded in one revolution, and four vertical synchronization frames are positioned radially at 90 degrees each. The diameter of the disc is 26 cm (10.2 inches), and on the front and back sides, up to 1]grams are recorded every 2 hours.Therefore, for the number of information pitches, there are 500 (ei) pitches on one disc. ] ~, making it extremely dense.

Therefore, such high-density information recording media are produced using the same press production equipment as conventional audio A° records. The monthly interest rate is harder than that of a general audio card, and video information signals, etc. are recorded with high density, and depending on the case (mold) structure, the information recording medium Heat may not be transmitted uniformly, and the effects of distortion and flatness of the outer circumference of the eyelid cover due to this will be reflected directly on the screen. Care must be taken.

It should be noted that the information recording medium is not limited to those described above, and can of course be applied to, for example, a video disc having a guide groove.

Further, as described above, consideration must be given to the trimming method. Therefore, the Ministry of the Invention and others devised a way to distribute heat uniformly inside the case (mold), and also configured the size of the mold to be more human-like than the R-shaped outer shape of the information recording medium. Concentrate distortion. We attempted to solve this problem in the following way, and the points in A are shown below in Figure 7 (Δ)...
This will be explained with reference to D). Here, Fig. 7 (Δ)−・(
J)) is an NrlJi side view of the press case, an explanatory view of the case of molding an information recording medium using the press case, and a side view of the completed information recording A1 body, respectively. Upper and lower cases (gold Δ'I) (23)
.

The size of (24) is determined by the final external shape.
Inboo (30cm), 10.2 inches from the inner circumference (
There is video information etc. in the part up to 26 cm), and the part outside of this is a non-recording part. In other words, 1. In the lower cases (23) and (24),
(36) (37) is the part of 3Qcm, (38) (39)
I accept the 26CI11 part.

In addition, (23Δ)......(23N>, (2
4△)・・・・・・・・・(24N) are grooves for heating and cooling, respectively. Among these grooves, for example, (23△)(
2/1. A'>(23N>(2/IN) is provided to the outside of the part f+ where the medium part (non-recorded part) (40) (41) continuous with the final outline is formed. Heat is transmitted evenly to the video information area, and the distorted area is the final external shape of the 26cm area (38).
(39) Since it was concentrated on the outer circumferential side, the required angle was obtained as the instep surface degree of the disc, and this seems to be due to the following reason.

? However, to form a disk, first a mold is heated to a predetermined temperature, the preformed part (cake) is brought onto the heated mold, and after pressing for a certain period of time (approximately 20 seconds). The process of cooling and covering the inside of the case (mold) is performed, but this heating and cooling is carried out from the outer periphery of the case to the inner periphery, and furthermore from the inner periphery to the outer periphery.
......(23N-).

(2/IA) This is done by flowing steam and water through (24N), and the temperature is uniform near the outermost periphery, which is the final part of this heating and cooling. This seems to be the cause of distortion at the outer periphery due to the lack of stability.

Therefore, according to the present invention, the outermost peripheral portion formed to be considerably larger than the final external shape, for example, the non-recorded portion (40
) (41), the present invention has a step IJ in which a portion corresponding to the final external dimension is formed in the outermost circumferential portion J, within the area 1i. In the case of an information recording medium that is press-molded in an il-necked manner, this effect of distortion at the outer periphery is not transmitted, and video information and the like are not affected in any way.

In addition, FIG. 7(B) shows the cake (21) of FIG. 7(A) in a press-molded state.

As is clear from this, the overflow portion (45) is formed by the non-recorded portion (44) and the 7[1 portion (46). This overflow part (45) is a knife (
47), and is formed into a final external shape of 10.2 inches (26 cm) as shown in FIG.

In this way, the information recording medium formed into an external shape that is more human than the predetermined external shape is then transferred by the gripper (3-5) to the rimming mechanism section 1, which is the second group in the present invention.

Here, a mechanism for transporting the disk in the manufacturing process of the information recording medium will be explained using FIGS. 2(C) and 2(A).

) The gripper (35) fixed to the turntable (51) presses down the overflow disk brought to the turntable (51) from the top, and the hemming mechanism such as a knife (47), which will be described later, forms the desired shape.

Of course, the gripper (35) releases the grip of A when it brings the disc with A-half 1 to a predetermined position.

(56) is a transport arm fixed to the main slide (49), which carries the disks checked by the check table section (57) to the next process, such as the stock section (88). Next, the gripper (35) fixed to the main slide (49)

The transfer of the partition plate will be explained with reference to FIGS. 9(Δ) to (D).

Figure 9 (A> is a side view showing the state before operation, Figure 9 (B) is a side view showing the operating state, and Figure 9 (C) is a side view showing the state in which the suction cup is activated and sucks one partition plate. , (D) is a side view showing a state in which a plurality of suction cups are provided.

(77) is an air cylinder placed on a support stand (8/I), and a suction cup (78) is fixed to its tip. Note that (79) is a 17-nozzle. .

(80) is a center shaft fixed to the center of the barrels 1 to (82), and a required number of partition plates (81) are placed above the center shirt.

(83) is a rail on which the air cylinder (77) is placed and the support stand (84) slides, (8E5) is a slider cylinder, and the tip (86) of the upper air cylinder is the support stand (8/ I).

Next, the information recording medium manufacturing apparatus according to the present invention configured and installed as described above is shown in FIG. Explain with reference to.

First, after the main power switch is turned on, the extruder (1)
The extruder motor, which is the driving means of the screwdriver 1, is rotated.
- < 3) rotates, and the material formed by this rotation is kneaded as appropriate in the steam flow path (7) heated to about 100"C to -200C, making it suitable for use in video discs, etc. The intermittently extruded material is intermittently extruded from the nozzle port (6) with a viscosity of (17) is molded into a cake cup (12
).

Since this space has the shape described above, the material to be molded, after coming into contact with the protrusion, is gradually pushed toward the four parts (12C) and (12D) of the space, which are the outer periphery. It's expanding.

When a predetermined amount of the material is fed, a switch (not shown) provided in the cylinder moves once to stop feeding the material to be molded, and the material to be molded filled in this space (17) is opened at a predetermined time. left in a state.

Then, after a predetermined period of time has elapsed, the filled material to be molded becomes a predetermined solidified state.

This solidified cake has approximately the same shape as the space (17) inside the cake cup.

Here, to explain in detail the requirements for the cake, first,
The outer periphery must be a smooth surface with no protrusions,
Second, it is required that there be no unevenness in temperature on the circumference, and third, that there are no small recesses or voids. By the way, the conventionally used cake cup has a roughly cylindrical shape with a flat top and bottom that extend completely to the peripheral surface.
It was.

This type of cake cup has protrusions on the outer periphery, which makes it difficult to mold the cake, and it is difficult to mold the cake without moisture on the circumference. difficult,
Furthermore, there was a drawback that small recesses (X5) were easily formed in the cake. Therefore, air and gas are trapped in the above-mentioned protrusions, recesses, and voids between the flat surface of the cake and the press case.

The trapped air or gas cannot escape when the press case is closed and is forced toward the cake side, forming defects such as voids, bulges, and depressions on the disk surface. If such a defect exists, for example, the molding on the pin 1 will be distorted, and the sword will not be able to track properly. Such defects are a very serious problem, and especially as mentioned above, there are 50 billion bits on one disk compared to the number of information bits, and the high-density bits are very small.
This is extremely undesirable for the A disk.

Also, since it is simply cylindrical when placed in a conventional cake cup,
Temperature unevenness occurs on the circumference between the part that is fed first and hardened first and the part that is fed last and hardened last, so when press forming, the elongation is different by 1 go and the thickness is uniform ↑ 1 It has the disadvantage that it cannot be removed, and also that distortion occurs on the outer periphery. This defect of distortion on the outer periphery is more fatal to the inner periphery than on the outer periphery, such as via Aγ disks where video information is recorded, and is something that cannot be accepted at all. It is.

According to the cake cup of the present invention, FIG. 4 (E,)
As is clearer, the shape 4 is approximately circular, and a through hole (21D) is provided in the center, and the outer diameter of the flat part on the lower side of the cake is the diameter of the innermost circumference of the groove of the disk. In the evening
1 and formed small, and the part other than the curvature is a circular recess.

Therefore, the cake molded using the cake cup of the present invention has the b1 recesses (21B) (21C) formed when the garlic is brought onto the press II (35) and press-molded. , no air is drawn in during molding,
4. There is no chance of scratches caused by air bubbles on the disk surface.

When the cake T is solidified into a predetermined shape by the Goo-1 nip in this manner, the upper cup (12A) is moved upward to a predetermined position by the upper cylinder (15).

This upward movement activates the switch, and the cylinder (19) slides to the right as shown in FIGS. 4(C) and 4(D). The moving cup (13) on which a predetermined cake is placed is brought onto the press (22).

When the movable cup (13) is brought to the press II (22), the upper U turbine (33) which also serves as a guide in the movable frame (30) is protruded one frame (31), and this movable cup ( 13) Insert the inner cake from above to hold the cake.

When the upper center pin and the through hole (34) hold the goo↑, the switch is activated, and the movable J knob (19) returns to the original position.

Thereafter, when the switch is actuated, the hydraulic sill (26) moves upward, and the cake held by the upper pin and the through hole is press-molded using the upper and lower molds that have been heated in advance. During this molding process, after pressing, heat and pressure is applied for about 20 seconds, followed by cooling for about 10 seconds.

As mentioned above, the upper and lower cases (23) and (24) each have grooves for heating and cooling inside them, and the grooves are at least the final outer diameter of the disk. Because the press-formed disk is placed outside the area where the continuous media portion is formed, the press-formed disk is, by its nature, formed into a shape that is considerably larger than the final external shape. The outer periphery, for example, the cut-out part (
42) and (43) with overflow that concentrates distortion.

In the present invention, a portion corresponding to the final external shape is provided considerably inward from this outermost periphery. In the information recording medium press-formed by J Manufacturing Equipment, GEL,
The distortion caused by such distortion at the outer periphery does not spread or break down, and there is no problem with the hemming section (42>(4, 3), which is edged by the hemming means).

When the predetermined press cycle ends η, the hydraulic cylinder <2
6) will dry up, but with this descent, the limit 1~ switch (not shown) will be activated, and this will cause the main slide (
49) moves in a predetermined direction.

By moving this main slide 49), a separate limit 1 switch is actuated, and the limit 1 switch is activated to move the 1 to 1 limit cylinder (58) to 1 limit in order to receive the disk with the A-bar flow. 1-Rear pin cylinder (5
9) and check table cylinder (74), subji 1
Tsuktable Schilling (75) both do 4-i-. The above disc with overflow is compatible with the main slide (
49) The fixed gripper (35) is actuated so that its fingers (not shown) close and grip the disc with overflow.

The fingers of the gripper are configured to close approximately 5 seconds after the start of cooling in the press-molded recycle.

Then, the main slide (49) moves forward (the direction of the arrow in Fig. 2 Δ is the forward direction).
etc. are transferred to the border structure. As the main slide (49) moves, the cake cup (12) containing the next cake is brought onto the press 1 (22).

At the bottom of the edging 1 consisting of a knife (47) etc. 4.11 As mentioned above, there is an over-slip disk gripped by the gripper (35) of the main slide (49). has been moved to this position (
When it comes to the edging n structure), the timer is activated and both the upper spine 1~ rimmer pin cylinder (58) and 11 b 1-
Since the rear pin cylinder (59) is provided, the movement of the main slide (49) to a predetermined position brings the 1-rimmer pin (60) to the highest position.

When the rimmer pin (60) is brought to the lowest position, the gripper (35)
The A-bar flow disc is moved downward along the rimmer pin (60) and placed on the turntable (51). (Fig. 8B) (Fig. 8C) A-The disc with part row is placed on the turn table (51), and the main slide (4
9) returns in the direction opposite to the arrow, the limit switches (not shown) installed in the frame (52) are operated, and this operation causes the I-knub l to the remarbin cylinders (5) to move to the first stage. By this descent, 1 to rimmer pin (6
0) is lowered, the fingers of the gripper (35) close to facilitate the return of the main slide (49).

In addition, when the main slide (49) returns, the gripper (35) returns to the upper frame (31), the movement 71 gnome (30), and grips the next overflow disk. Make preparations for

When the main slide (49) returns, the breath plate 1 to cylinder (50) operate, and a suction cup (
53) attached to the breather (・-1-pull (48
) descends to the position of the disk with the A-part row, and this disk is suctioned by 1tA (53), and is pressed onto the turntable (51). , (Fig. 8D
) When the breath table (48〉) descends to the position where it presses the disc with the A-part row, the air cylinder for flow bushing 1 is activated, which causes the shirt j~(
55) is pushed, and this shirt] to (55> presses a portion of the overflow 70 to bring this portion of the overflow into contact with the tip of the knife (47).

Thereafter, the turntable (51
) rotates, a portion of the overflow is cut off by the no-if (47).

The disk with an overflow is trimmed to a desired external shape using a trimming mechanism such as a knife (47),
In addition, press forming of the next disc with one over half is done using a press of 1 m (2'2), and the hydraulic Ring (2)
6) is lowered, and when the switch is activated in accordance with the lowering of the oil cylinder, the air cylinder for the flow cylinder becomes inactive, and the cylinder 17 (l-<55) returns to its original position.

t, the above-mentioned edging is completed by the time the press molding cycle is completed above the press 1 m (22>).

Of course, at this time, the next cake brought onto the press (22) by the cookie cutter as described above is press-formed in a predetermined manner at 41b.

On the other hand, a part of the trimmed A-barf (■) is placed on the claw part (67) provided on the sliding automatic Y[ on the ring (6G), which is located slightly on the side of the upper surface of the turntable (51). .

When the disc, which has been sucked by the suction cup (53) and has been trimmed to a predetermined external dimension, returns to the predetermined position and returns to the upper position, a switch (not shown) is activated, which causes the air cylinder (6
1) (62) is activated and the system 11 connected to it is activated.

On the other hand, when the flow table (69) returns to its original position,
A switch (not shown) is activated, and the return table cylinder (58) is activated again, causing the turntable (51) to rise and return to the position (.DELTA.) in FIG.

Then, when the predetermined press molding is completed and the disk with the A-bar 70 is molded, the same operation as above is performed.
This disc with overflow is the main slide (
49) gripped by the fingers of the upper gripper (35),
As the main slide (49) moves forward, it is transferred to a edging structure such as a re-knife (47). That is, at this time, on the main slide (49), the "1st disk which has already been rimmed and the next disk which has been press-molded are respectively pressed by the pressure I/-j-pull and the gripper (
35).

Therefore, the first disk being trimmed by this movement of the main slide (49) moves to the next check table section (t?nzer 7-pull section (57)), and the disk to the right of the next overflow section Each of the edges is conveyed to a predetermined position of a edging mechanism such as a knife (<47). However, when the main slide (49) moves in the direction of the arrow in FIG.
When it is brought to the point, the above-mentioned predetermined time has elapsed and the operation J
A timer is activated, and a hold table cylinder (74) and a remarbin cylinder (5B>) are placed on the -1 side of the transferred first disk and the next overflow disk.・Chu 2-cylinder (59
) rises, and along with this, 1-remarbin (
60) and the check table (73) are raised, the first disk and the next disk with overflow are lowered along the 1-remargin bin (60), the bin (76), respectively, and - the respective duffle Prepare the container to be placed on top.

In addition, the disk with an overflow brought to the edging machine 474 section, such as the knife (47), is 1-
Rimmed and prefushi 1? - It is sucked by the suction cup (53) of the table (/+8) and waits for the next process.

On the other hand, when the first disk that has been trimmed to the desired shape is brought onto the check table (73), it is placed on the press table (/18). I (E53) becomes inactive and the disk is placed on this check table (73). At this time, the main slide (49) is of course returned to its original position.

In addition, when the main slide returns 9m, the check table (73) is lowered and the sub 1 to remarbin cylinders (59) are lowered by one step, as described later, so the main slide is easy. Return to original position. In addition, as described above, the gripper (35), press 1 seat table (48), flow button (54), and transport arm (/I9) are installed on this main slide (/I9), and the transport arm (56) The gripper (35) is indicated by X, Y, and Z in the figure.

Main slides (4

When a disk is placed on the check table (73) l, only the check table cylinder (74) descends,
That is, the check-j-pull (73) is lowered by one stage and a checking means (not shown) performs a check on the disc process. When activated, the check-me-pulls (73) move up to just below the suction cups (87) installed at the tips (8G) of the transport arms (4).

After that, a timer (not shown) is activated in response to this upward movement, and as a result, the tip of the 1lfJ feeding arm (8
The suction cup (87) installed in G) uses fr to suction the disk (D) on the check daple (73), and waits for the next step, the suction part (88). .

Absorption%? When the disk r8 is placed on l1f (87), the timer is activated and the check table cylinder (74) and Zabuji I vine table cylinder (75) are lowered to the bar (
2 steps) to facilitate sliding of the main slide ('1.9) to the next process. Incidentally, it goes without saying that this Chikokue culm is finished within the press molding cycle of the press machine (22). Similarly, the next disk of the desired shape, which has been trimmed by the edging mechanism such as the knife (47), is also trimmed by the suction cup (53) of the pressure V-table (48).
) and is waiting for the next process.

In this way, when the first disk and the second disk, which is the next disk, finish the checker culm and edging process and move on to the next process, the third disk moves to the press. 41 (22), and gripped by a gripper (35) as above.Then, as the hydraulic cylinder (26) lowers, the limit switch is activated, and the main slide (49) moves forward. The first disk is held at point W in Figure 2 (A), the second disk is held at point 7, and the third disk is held at point Y in Figure 2 (A). Incidentally, the operations at point Y and point 7 are the same as those described above, but will not be discussed here.

When the limit switch is activated as the hydraulic cylinder (26) descends, the J: Remain slide (/I9) moves forward and moves to the first position.
Bring the disc to point W in Figure 2 (△).
The J: retable is attached to a cylinder (not shown) on the transfer arm (5

The upward movement of this table activates a timer (not shown), which releases the suction of the suction cup (87), places the first disk on the disk receiver (pallet) (89), and this places the air cylinder. When the main slide (49) is activated and the door pull is lowered and covered, the main slide (49) will move as shown in Figure 2 (A).
The disk returns to a predetermined position inside and waits for the disk that has completed each T culm.

NaJ3, this main slide (49)'s 1~tsuku section (
88) and returning to the predetermined position C in FIG. 2 (△) is, of course, quick.

A predetermined number of completed discs (
When five sheets) are placed, a limit switch (not shown) is activated and the barrels 1 to (82) are lowered.

The operation of this limit switch causes the air cylinder (7
