When peeling a plate-shaped product after molding and firing from the molding surface of a mold,
Shell spinners suspended at equal intervals around the lower part of the turntable are rotated to peel off the plate-shaped product that is attached to the molding surface, and then wound and roll-formed inside the shell spinner. The peeling cutter attached to the shell spinner strongly hits the molding surface of the mold, and there is a risk that the cutter or the molding surface of the mold may be damaged or broken.

SUMMARY OF THE INVENTION An object of the present invention is to provide a mold evacuation feeding device for peeling off a plate-shaped product in a cone cup manufacturing machine, which eliminates the above-mentioned conventional disadvantages.

First, to give an overview of the corn cup making machine,
In FIG. 1, after a certain amount of raw material is supplied to the molding surface 1a of the lower mold 1 of the mold A, the mold A with the upper mold 2 closed is transferred to the oven 3 by a conveying chain B.
When the upper mold 2 is moved inside and exits the oven 3, the upper mold 2 is opened again by the correlated guiding function of the opening/closing roller 4 of the upper mold 2 and a pair of parallel guide rails 5 and 6. When the upper mold 2 is opened, the fan-shaped plate product C baked in the oven 3 separates from the smooth molding surface 1a of the lower mold 1, and the lattice pattern grooves 7 of the upper mold 2 Since the shell spinners 8 are attached to the molding surface 2a of the upper mold 2 having Therefore, the plate-shaped product C is peeled off from the upper die molding surface 2a, rolled into the shell spinner 8, and roll-formed into a conical cylinder shape.

As shown in FIG. 2, the shell spinner 8 has a structure for winding up the plate-like product C. As shown in FIG. A strip-shaped cutter 11 is attached to the inner surface notch step 10 of the protrusion 8a extending in the tangential direction, and the cutting edge of the cutter 11 is slightly protruded at an angle equal to the angle of inclination of the side surface of the shell spinner 8. . Further, a rotatable core 12 is fitted concentrically into the shell spinner 8, and a conical cylindrical mold hole 13 is formed between the two fittings. A locking tooth 14 for locking the product is provided vertically.

When peeling the plate-shaped product C, the mold A is the upper mold 2.
is moved straight in the direction of arrow W in FIG. 2 by the conveying chain B in the open state (the state shown in FIG. 3). On the other hand, the shell spinner 8 is turning in the direction of arrow V, which is the opposite direction to the advancing direction of the upper die 2, due to the rotation of the turntable D, so when the shell spinner 8 approaches the upper die 2, the cutter 11 The cutting edge of the plate comes into sliding contact with the molding surface 2a of the upper mold 2 and peels off the front end of the plate-shaped product C, and by the rotational movement of the shell spinner 8 and the straight movement of the upper mold 2, the plate-shaped product C is peeled off. , and the subsequent product C into the conical cylindrical shaped hole 13 inside the shell spinner 8.
The winding is performed continuously.

In this case, the cutting edge of the cutter 11 attached to the shell spinner 8, which is rotating and moving, draws a circumferential locus with respect to the upper die 2, which moves straight. In order to achieve sliding contact with uniform contact pressure over the period of time, it is necessary to run the mold A along the circumferential locus of the cutting edge of the cutter 11 when the plate-shaped product C is peeled off. be.

Therefore, the specific structure of the mold evacuation feeding device when peeling off a plate-shaped product in the cone cup manufacturing machine according to the present invention will be described in detail below.

17 is a bearing means for the central grain portion of the disc member 16, and 18 is a gear wheel attached to the lower surface of the disc member 16. Since this gear wheel 18 is configured to be interlocked with the driving means of the die conveying chain B via various gears and chain wheels (not shown), the turntable D is synchronized with the running speed of the die A. It rotates continuously in a predetermined direction at an appropriate speed.

Further, an appropriate number of shell spinners 8 are hung at equal intervals on the lower outer periphery of the disc member 16. The shell spinner 8 is rotated on a circumferential locus centered on the shaft 15 by the rotation of the turntable D.

A is the mold mentioned above, and the mold A has a pivot 19.
The lower mold 1 has an upper mold 2 and a lower mold 1 which are configured to be openable and closable with the metal mold conveying chain B as a fulcrum. It is supported and attached so that it can move laterally with respect to the direction of movement of mold A. 22 is a connecting shaft connecting the chain links 20 and 21 in a bendable manner;
Reference numerals 23 and 24 designate rollers for running the chain pivotally attached to the protruding portions at both ends of each of the connecting shafts 22, and 25 and 26 designate rails for supporting the running of the rollers 23 and 24. Further, an upper mold 2 having a molding surface 2a with a grid pattern groove 7.
An upper die opening/closing roller 4 is rotatably attached to the center of the tip of the roller 4, which is mounted on an extension line orthogonal to the pivot shaft 19, and is installed between a pair of guide rails 5 and 6, which are installed parallel to each other, as shown in FIG. The upper mold 2 is configured to open or close with the lower mold 1 at a predetermined position while being guided by the upper mold 2.

In FIGS. 4 and 5, 27 is the lower mold 1
It is a guide rail for lower mold relief feeding provided protruding from the lower surface, and the lower end surface of the guide rail 27 is provided with a lower mold 1.
A concave groove section 28 extending in the direction of movement is provided, and a convex curve 29a formed on the opposing inner surfaces of the concave groove section 28 in order to move the lower die 1, which can run straight, laterally in the direction of arrow X. , forming a curved track portion 29 consisting of a concave curve 29b facing this. The radius of curvature of the curved track portion 29 is formed to match the radius of curvature of the circumferential trajectory of the cutting edge portion of the cutter 11 of each shell spinner 8 that rotates as the turntable D rotates. Reference numeral 30 denotes a support shaft fixedly disposed below the lower mold 1 at the position where the shell spinner 8 that can be turned and the mold A that can travel straight are closest to each other. The guide roller 31 for mold escape feeding is rotatably pivoted and mounted at an accurate position so that it can move into and out of the curved track portion 29.

Reference numeral 32 denotes an upper die escape feed means disposed above the lower die escape feed guide roller 31, and the upper die escape feed means 32 includes a fixed support member 33 fixed to the machine body, An upper mold guide member 34 is slidably placed on the fixed support member 33, and a pair of supports are provided on the fixed support member 33 on the left and right sides with shaft ends protruding from the rear end of the upper mold guide member 34. a shaft 35; and the upper mold guide member 34 provided on the outer periphery of the support shaft 35.
A compression spring 36 for constantly biasing in the direction of arrow Y in FIG. and a guide shaft 38 for guiding and regulating the sliding direction of 34. Then,
An inclined raceway surface 39 that can come into surface contact with the rolling surface of the opening/closing roller 4 of the upper mold 2 in the open state is formed at the tip of the upper mold guide member 34 that protrudes from the fixed support member 33. The inclined raceway surface 39 is a relief raceway surface 39 that allows the molding surface of the upper mold 2 to move slightly laterally during progress in order to follow the circumferential locus of the cutting edge of the cutter 11 drawn by the rotation of the shell spinner 8. ' is formed. Furthermore, in a pair of guide rails 5 and 6 installed in parallel to open and close the upper mold 2 while guiding the opening/closing roller 4 of the upper mold 2,
As shown in FIG. 10, one of the guide rails 5 located on the side of the upper die relief feeding means 32 is interrupted at the attachment point of the upper die guide member 34,
The guiding function is performed by the inclined track surface 39 of the upper mold guide member 34, and the opening/closing roller 4 rolls between the other guide rail 6 and the inclined track surface 39, and the cutter 11 A rail portion facing the inclined track surface 39 is formed to extend in substantially the same shape as the inclined track surface 39 and is installed parallel to the inclined track surface 39 so as to be able to move laterally in accordance with the circumferential locus of the cutting edge.

In the above configuration, each shell spinner 8 rotates around the shaft 15 as the turntable D rotates. Meanwhile, in synchronization with the rotation of the turntable D, the mold A is transferred to the conveyor chain B.
Just before the mold A approaches the turning trajectory of the shell spinner 8, the opening/closing roller 4 of the upper mold 2 is moved between a pair of guard rails 5 and 6. The upper mold 2 is released from the lower mold 1 while being guided between them, and the mold A moves straight in this state.

Next, the upper molding surface 2a of the mold A that can run straight
The cutter 11 of the shell spinner 8 that can be turned
At the time when the cutting edge comes into contact, the die A moves straight ahead and performs the following relief feed operation.

A curved track portion 2 of a concave groove of a guide rail 27 for relief feeding of the lower mold protruding from the lower surface of the lower mold 1 that can run straight.
At 9, a lower die escape feed guide roller 31 pivotally attached to the support shaft 30 is inserted. When the lower die 1 moves further with the guide roller 31 inserted into the curved track section 29, the guide roller 31 provided at the fixed position contacts the convex curved surface 29a of the curved track section 29 and rotates as a result of the rotation. While doing so, push this convex curved surface 29a. Therefore, while the lower mold 1 is traveling straight, it is at the position of the guide roller 31 indicated by the arrow X in FIG.
The lower mold 1 is moved laterally in the direction to allow the lower mold 1 to escape.
The concave curved surface 29b formed opposite to the convex curved surface 29a of the curved track portion 29 has the function of guiding the escape feed direction of the lower die 1 with respect to the fixed position guide roller 31 together with the convex curved surface 29a. is fulfilled.

When the lower mold 1 moves further forward, the curved track portion 29 of the lower mold 1 separates from the fixed position guide roller 31, so the lower mold 1 moves laterally in the direction opposite to the arrow X direction and returns to its original straight traveling direction. Return to the trajectory and continue driving straight.

On the other hand, when the upper mold 2 is in the open state, as shown in FIG. 6 and rolls while being guided between them and advances in the direction of arrow Z, so that the upper mold 2 moves laterally along the shape of the inclined track surface 39 and the guide rail 6 facing it. Then, the upper die 2 is fed out.

Therefore, at the time when the cutting edge of the cutter 11 of the rotatable shell spinner 8 comes into contact with the molding surface 2a of the upper mold 2 and draws a circumferential trajectory, it peels off the plate-shaped product C attached to the upper mold molding surface 2a. Then, the lower die 1 and the upper die 2 synchronously escape in the lateral direction while traveling straight in accordance with the circumferential locus of the cutting edge of the cutter 11, so that the cutting edge of the cutter 11
It slides along the molding surface 2a.

In addition, in FIG. 10, the opening/closing roller 4 of the upper mold 2 is rotated from the position of the protruding end of the inclined raceway surface 39 of the upper mold escape feed means 32 to the escape raceway surface 39'. The cutting edge of the cutter 11 is the upper molding surface 2
a, but when the cutting edge of the rotatable cutter 11 acts on the inclined raceway surface 39 with a force greater than a predetermined pressure, the upper mold guide member 34 resists the stored force of the compression spring 36. Since the cutter 11 momentarily slides in the direction opposite to the direction of the arrow Y and is buffered, the cutting edge of the cutter 11 in contact with the molding surface 2a of the upper mold 2 always maintains a constant contact pressure. In addition, the upper mold guide member 3
4, and a guide shaft 3 fitted into the long hole 37 and screwed onto the fixed support member 33 to protrude.
8, the inclined track surface 39 of the upper mold guide member 34
Since the separation distance between the upper mold opening and closing roller 4 is maintained, the load is not applied to the molding surface 2a of the upper mold 2 by the cutting edge of the cutter 11. The upper die guide member 34 is moved laterally only when this load is released, and the cutter 11 is applied to the upper die molding surface 2a.
This reduces the contact pressure at the cutting edge of the blade and promotes its buffering function.

When the plate-shaped product C adhering to the molding surface 2a of the upper mold is peeled off with the cutter 11 and rolled into the conical cylindrical mold hole 13 of the shell spinner 8, the next shell spinner 8 rotates. Then, the mold A at the rear is approached, and the product peeling operation similar to that described above is continuously performed.

A curved track portion 43 is formed. The radius of curvature of this curved track portion 43 is the same as the radius of curvature of the circumferential trajectory of the cutting edge portion of the cutter 11 of each shell spinner 8 that rotates as the turntable D rotates.

The mold A runs straight and the cutting edge of the cutter 11 of the shell spinner 8 that can rotate is the molding surface 2 of the upper mold 2.
At the time when it comes into contact with a, the guide roller 41 for lower die escape feed provided on the lower die 1 enters the concave groove section 44 of the guide rail 42 for lower die escape feed and rolls on the curved track section 43. As the lower die 1 moves forward,
As the convex curved surface 43a of the curved track portion 43 pushes against the guide roller 41, the lower die 1 is moved laterally in the direction of the arrow X in FIG. 7 and is ejected.

8 and 9 show another modified embodiment of the relief feed structure of the lower die 1, in which a lower die relief feed guide rail 45 is provided at one end of the lower die 1.
A concave groove strip 46 is provided on the upper end surface of the guide rail 45 for lower mold escape feeding, and this concave groove strip 46 is provided in a protruding manner.
A curved track portion 47 is formed between the inner surface facing side wall portions. The curved surface shape of this curved track section 47 has the same diameter as the radius of curvature of the curved track section 29 shown in FIG. 5 described above. On the other hand, the lower mold 1 is located at the position where the shell spinner 8, which can be turned, and the mold A, which can travel straight, are closest to each other.
A fixing member 48 is fixed to the body on one side, and a lower die escape feed guide roller 50 is rotatably pivoted to a vertical shaft 49 at the protruding tip of the fixing member 48.
The escape-feeding operation of the lower mold 1 corresponding to the guide roller 50 provided at a fixed position is the same as in the embodiment shown in FIGS. 4 and 5 described above.

As mentioned above, in the relief structure of the lower mold 1,
In both the embodiments shown in FIGS. 4 and 5 and FIGS. 8 and 9, the curved track portion 29 is moved by lower mold escape feed guide rollers 31 and 50 provided at fixed positions. , 47 have a convex shape toward the shell spinner 8 side, and in the embodiments shown in FIGS. The curved track portion 43 has a convex shape on the side opposite to the shell spinner 8 side, but in both cases, the lower die 1 is
