Abstract

PURPOSE:To enable the distance between an upper metal die and a lower metal die to widen suficiently and to enable a cake to be arranged at predetermined position by press-forming the cake into a disk between the upper metal die and the lower metal die with the lower metal die raised in two steps. CONSTITUTION:The cake made by a cake producing device for a disk is dropped onto a lower metal die 35, and successively pressurized oil is introduced into the oil pressure chamber 44 in a auxiliary cylinder 42 from a conduit 46 by opening only a switch valve 46a. When a ram 41 is raised, with this action a subpiston 39 and a main piston 29 are also raised, and the lower metal die 36 is lifted slightly. Next, the pressurized oil is introduced into the oil pressure chamber 43 in a subcylinder 38 from a conduit 45 by opening a switch valve 45a. The pressurized oil entering into the oil pressure chamber 43 raises the subpiston 39 slightly. When the subpiston 39 is raised, its lower end surface is separated from the upper end surface of a ram 41, and the pressurized oil entering into a flowing path 39a reaches a oil pressure chamber 40 in a main cylinder 28. The pressurized oil entering into the oil pressure chamber 40 raises a main piston 30, and the lower metal die is press-operated against the upper metal die 20, thereby forming the cake into the disk.

Description

[Detailed description of the invention] The present invention relates to a disk manufacturing apparatus.

In this type of disk manufacturing equipment, a cake is transferred between a press equipped with a stamper, placed on a lower mold, and then pressed by driving a hydraulic cylinder. , labels are usually attached to the top and bottom surfaces of the cake. The label is then bent by the heat of the cake, so that the opposing portions hang down from the forks used to grasp and transport the cake.

Therefore, when the fork was moved, the hanging portion of the label rubbed against the stamper, often damaging the stamper and rendering it unusable. Therefore, it may be possible to widen the gap between the upper and lower molds, but in this case, when the cake is dropped onto the four lower molds, the falling distance becomes longer, making it difficult to place the cake in a predetermined position. Ta.

The present invention has been made to solve the above-mentioned conventional drawbacks, and its purpose is to make it possible to sufficiently widen the gap between the upper and lower molds, and to prevent the cake from falling when left on the lower mold. To provide a disk manufacturing device capable of shortening the distance and arranging a cake at a predetermined position.

The following is an example of the present invention. This will be explained with reference to the drawings. In FIG. 1, A is a disk cake manufacturing device, B is a disk molding device, and two rails 1 connect them.

First, the disk cake manufacturing apparatus will be explained.

In FIG. 1, reference numeral 2 denotes a base, which is installed on the rail 1 and can slide together with the rail 1 up to the position of the disk forming device 8. A lower frame 3 is attached to the base 2, and has a notch 3a and a protrusion 3b.
is formed.

3C is a hole for cake injection. As is clear from FIG. 2, a lower auxiliary plate 4 is disposed below the lower frame 3, and is raised by a cylinder 5, with a protrusion 4a projecting from the center of the plate 4. It fits into the notch 3a of the plate to form a flat plate-like lower base (Fig. 3, symbol l1l).
.

In FIG. 2, reference numeral 6 denotes a frame, on both sides of which rods 7 are fitted so as to be vertically slidable.

It is integrally connected to the upper end of the rod 7 by a horizontal frame 8,
It is designed to be driven up and down by a cylinder 9 attached to its center. On the other hand, the lower end of the rod 7 is integrally connected by an upper frame 10. The upper underframe
At the lower part of O, there is a 2
A heavy cylindrical molding frame is formed. The lower parts of two rods 11 are also fitted into the upper frame 10, and a ring-shaped upper part 112 is connected to the lower end of the upper frame 10 via a connecting rod 11a.
is installed. The upper part of the rod 11 passes through a stopper 7a attached to the frame 6 and is integrally connected to the sliding horizontal frame 13.

Both ends of the horizontal frame 13 are slidably fitted into the rod 7, and an operating piece 13a for operating a switch 14 is attached to the negative side thereof. 7a is a stopper fixed to the rod 7. Reference numeral 15 denotes a tension spring, the lower end of which is locked to the upper underframe lO via a locking piece 15a, and the upper end connected to the center of the sliding horizontal frame 13.

Next, the operation of the disk cake manufacturing apparatus A will be explained.

First, as shown in FIG.
The lower base of the cake mold is formed by fitting it into the mold. In parallel with the above operation, the cylinder 9 is operated to lower the upper frame 10 via the horizontal frame 8 and rod 7. As the upper frame 1o descends, the sliding horizontal frame 13 also descends while contacting the stopper 7a of the rod 7 via the locking piece 15a and the tension spring 15. Eventually, the sliding horizontal frame 13 comes into contact with the stopper 12 to stop its descent, and the upper cover 12 attached to the lower part of the rod 11 is stopped at a predetermined position.

Despite the stoppage of the sliding horizontal frame 13, the upper underframe 10 continues to descend while stretching the tension spring 15, and the lower end surfaces of both wall rings 10a, 10b of the lower part thereof protrude from the lower underframe 3. It stops when it comes into contact with the lower stand made up of the section 4a (see Fig. 3).

In this state, a donut-shaped space surrounded by the lower stand (3, 4a), the inner wall ring 10a, the long wall 11 [10b and the upper part 112] is formed. As is clear from FIG. 1, one example of the outer wall ring 10b is partially cut out, and the protrusion 3b of the lower frame 3 fits into this part, forming a complete annular space. It is now possible to do so.

As the sliding horizontal frame 13 stops, the operating piece 13a attached to the side pushes the switch 14, and the cake material is injected from the cake injection hole 3c leading into the space,
Form a doughnut-shaped cake.

When the molding of the cake is completed, the cylinder 9 operates to pull up the upper frame 10, that is, the inner and outer mold rings 10a and 10b. At this time, the sliding horizontal frame 13 remains in contact with the stopper 6a due to the tensile force of the fully extended tension spring 15.
The upper lid 12 below the rod 11, which is integrated with this, remains in the position at the time of molding, and
The cake is pressed down from above so that it does not rise as the cake rises. The lower ends of the mold rings 10a and 10b are shown in FIG.
When the rod 7 rises to the upper level, the strike flange 7a of the rod 7 comes into contact with the sliding horizontal frame 13, causing it to rise together and also pull up the upper part 112.

At the same time, the cylinder 5 also works to lower the lower pedestal auxiliary plate 4, leaving the formed doughnut-shaped cake on the lower pedestal frame 3. Then, the base 2 moves together with the rails 1 and carries the cake to the disk forming device B.

Next, the structure of the disk molding device will be explained. Fourth
In the figure, 16 is a frame, and cylinders 17 are installed on the upper left and right sides of the frame.

A rod 17a extending downward from the cylinder 17 is attached with an 0-piece rod 18, and a cutout groove 18a is formed in the lower end thereof toward the center.

A flange 19a protruding from the side of the upper mold mounting plate 19 is fitted into the cutout groove 18a, and when the locking rod 18 is pulled up by the cylinder 17, the upper mold mounting plate 19 is attached to the lower surface of the frame 16. It is fixed by crimping, and when the locking rod 18 is lowered, the upper die mounting plate 19 is attached to the frame 16.
It can be pulled out away from the bottom surface and toward the front as shown in Figure 4.

An upper mold 20 is integrally fixed to the lower side of the upper mold mount 19 with bolts 21.

A cylinder 22 is also attached to the frame 16, and the upper mold 20 is fixed at the press position by inserting the lock pin 22a into the hole 19b of the upper mold mounting plate 19 and the hole of the upper mold 20. ing. As shown in FIG.
b is formed so that cooling water flows in from one of the U gold 20c and 20cl and flows out from the other.

A cylindrical top center 23 is provided at the center of the upper mold 20.
is fitted, and the center bin 24 is inserted. Reference numeral 27 is a bottle for positioning with the lower mold, which will be described later.

In FIG. 4, 28 is a main cylinder for the lower mold, and rods 29 are attached to flange portions 28a on both sides thereof, and are integrally connected to the frame 16. A main piston 20 is housed in the main cylinder so as to be vertically slidable, and a bolster 31 is fixed to the upper end of the main piston 20 by bolts 32.

A door 31a is attached to the side of the bolster 31 to set the bolster 31 in the correct position relative to the main cylinder 28. A locking portion 31b is formed on the upper surface of the bolster 31, and is fitted into a flange 33a of the lower die mounting plate 33. Therefore, the lower die mounting plate 3
3 can also be pulled out toward the front of the fourth instep similarly to the upper die mounting plate 19. The lower die mounting plate 33 is integrally set by fitting the pin 34a of the cylinder 34 into the hole 31c of the bolster 31 and the hole 33b of the mounting plate 33.

The lower mold block 35 is mounted on the lower mold mounting plate 33) 33
It is designed to be integrally fixed by c. As shown in FIG. 8, a circular groove 35a is formed on the upper surface of the lower mold block 35, into which the lower mold 36 is fitted.

The lower mold 36 is fixed to the block 35 by a pin 36a. A flow path 36b for cooling water is also formed in the lower mold 36, and the cooling water is introduced from the inflow mouthpiece 35b attached to both ends of the flowpath 36b, and the cooling water is introduced into the flow passageway 36b from the inlet mouthpiece 35b attached to both ends of the flowpath 36b.
It is designed to be discharged from A cylindrical bottom center 37 is fitted into the center of the lower mold 36, into which the tip of the center pin 24 is fitted.

As is clear from FIG. 5, the tip of the center pin U has two steps, and the inlet end of the bottom center 37 that fits therein is also stepped, so misalignment can be avoided. Even if this occurs, it will be corrected. A hole 35d for centering is formed in the side of the lower mold prong 35, into which the alignment pin 27 of the upper mold 20 is fitted during pressing.

Further, stampers are attached to the upper mold 20 and the lower mold 36 by appropriate means.

A sub-cylinder 38 is further attached to the lower end of the main cylinder 28, and a sub-piston 39 is accommodated therein. The sub-piston 39 is fixed to the lower end of the main piston 30 and can move up and down together. A hydraulic flow path 39a is formed in the sub-piston 39, and the lower end surface of the piston 39 and the main cylinder 2.
8 hydraulic chambers 40 are connected to each other. Reference numeral 41 denotes a ram, which is housed in an auxiliary cylinder 42 attached to the lower end of the auxiliary cylinder 38, whose upper end surface abuts the lower end surface of the auxiliary piston 39, and which opens at the lower end of the flow path 39a. It is designed to block the area. A hydraulic chamber 43 below the sub-piston 39 and a hydraulic chamber 44 below the ram 41 are each connected to a conduit 45.
46 to a hydraulic pump (not shown).

45a and 46a are switching valves.

Next, a description will be given of how to align the axial center of the retaining mold and the axial center of the lower mold of the disk molding apparatus. First, in FIG. 4, after pulling up the center bin 24 into the frame 16, the cylinder 22 is activated to pull out the lock pin 22a, and the cylinder 17 is activated to lower the lock rod 18 slightly to remove the upper die mounting plate. 19 and the upper mold 20 are pulled out together.

On the other hand, the cylinder 34 is operated to pull out the pin 34a from the hole 33b, the lock portion 31a is loosened to release the pressing force of the flange 33a, and the lower mold mounting plate 33 and the lower mold block 35 are pulled out together.

In addition, before the core stand, the top center 23 and bottom center 37 are removed, the bolt 33C is removed, and the lower mold block 35 is separated from the lower mold mounting plate 33.
In addition, all of the 3" 6a have been loosened and the lower mold 36
can be moved slightly laterally with respect to the lower mold block 35.

Therefore, with the upper and lower hydraulic mounting plates 19 and 33 pulled out as described above, the lower hydraulic system is operated to

is raised, the hole 35d is fitted into the pin 27 of the upper mold 20, and the lower mold pro-hole 35 and the upper mold 20 are fixed. In this state, a core mounting jig (not shown) is inserted into the core hole of each of the molds 20 and 36 from which the top center 23 and bottom center 37 have been removed. Since the outer diameter of the jig is expanded by heating, the shaft holes of both molds 20 and 36 are accurately centered. In this state, the lower mold block 35 is integrally fixed to the lower mold 36 by tightening the pin 36a, and the core mounting jig is cooled to reduce its outer diameter and then pulled out. Next, Pol) 33
c, and attach the lower mold block 35 to the lower mold mounting plate 3.
3, and push in the upper mold full mounting plate 19 and the lower mold mounting plate 33 to set them accurately at the press position.

Next, the operation of the disk forming apparatus will be explained. In FIG. 1, as mentioned above, the disk cake manufacturing apparatus A
When the cake C manufactured by C is fed by the lower frame 3 onto the lower mold 35 with a slight gap as shown in FIG. The tip part fits into the bottom center 37. In this state, when the lower frame 3 is pulled back to its original position, the cake C falls onto the lower mold 35.

Then, as shown in FIG. 6, only the switching valve 46a is opened to introduce pressure oil from the pipe line 46 into the hydraulic chamber 44 in the auxiliary cylinder 42, and when the ram 41 is pushed up, the auxiliary piston is 39 and the main piston 29 are also pushed up, and the stopper 11
Slightly increase 36.

Next, open the switching valve 45a to connect the pipe 45 to the sub cylinder 3.
Pressure oil is introduced into the hydraulic chamber 43 of No. 8. The pressure oil that has entered the hydraulic chamber 43 enters a ring-shaped slit 43a formed above and presses the step surface 39b of the sub-piston 39, thereby pushing the sub-piston 39 slightly upward. When the secondary piston 39 is pushed up, its lower end surface separates from the upper end surface of the ram 41,
A gap is formed in the frame, and the pressure oil enters the flow path 39a through the gap and reaches the hydraulic chamber 40 of the main cylinder 28.

The pressure oil that has entered the hydraulic chamber 40 pushes up the main piston 30 as shown in FIG. 7, presses the lower mold 36 toward the upper mold 20, and forms the cake C into a disk. Incidentally, as the lower mold 36 moves upward, the center bin 24
is pushed back while being fitted into the bottom center 37.

When the press operation is completed, the pressure in the pipes 45 and 46 is removed, and the pressure oil in the hydraulic chamber 40 flows through the flow path 39a and into the hydraulic chamber 43.
As a result, the main piston 30 descends due to its weight, separating the lower mold 36 from the upper mold 20 and lowering it. Simultaneously with the lowering of the main piston 30, that is, the sub-piston 39 integrated therewith, the ram 41 also descends to its original position due to its weight, and the lower end surface of the sub-piston 39 abuts the upper end surface of the ram 41, causing the lower mold 36 to also lowers to its original position.

The disk press-formed as described above is removed from the mold 36 as the rail 1 moves while being held by the holding plate 1a attached to the inside of the rail 1, as shown in FIG. At the same time, the next cake C is supplied.

In the present invention, the lower mold is raised in two stages as described above, so the lower mold is raised during the transfer of the cake.

The lower mold is lowered to the lowest position, and when the cake falls after the cake is transferred, the lower mold is raised one step and the cake is placed in a predetermined position. This has the advantage of not causing any damage, and even if the cake falls into the lower mold, the power can be distributed to a predetermined position.
