Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a flare cone cup molding die for molding a flare cone cup product containing soft cream, whipped cream, chocolate or the like.

[Conventional technology]

Conventional flare-type corn cup manufacturing equipment
As disclosed in 1-12628, the mixed material supplied to a fan-shaped flat molding surface of a mold including an upper mold and a lower mold is baked into a fan-shaped plate-shaped product in an oven. There is a flaky cone cup product obtained by peeling a plate-shaped product from a molding surface of an upper mold by a cutter of a shell spinner, winding the product around a rotating core in a molding hole inside the shell spinner, and roll-molding the product. According to such an apparatus, without causing seizure of the corn cup product and damage of the corn cup product due to the seizure,
It is now possible to produce flared corn cup products.

Inside the shell spinner, a large-diameter hole portion, a stepped molding portion, and an inverted conical hole portion are formed in series, and are formed by this shell spinner and a core fitted in the shell spinner. Corn cup products are, for example,
As shown in FIG. 14, the shell spinner has a large diameter portion 52, a stepped molding portion, and a large diameter portion 52, a stepped portion 53, and an inverted conical portion 54, which correspond to the inverted conical portion, respectively. It becomes a stepped flared cone cup product 51.

[Problems to be solved by the device]

However, when the flared corn cup product 51 is developed, as shown in FIG. 15, in particular, the curvatures of the large-diameter portion 52 and the stepped portion 53 are greatly different, and as shown in FIG. 16, when involving sectorial plate-shaped product J into the shell spinner, large deformations of forming a hatched portion 55 surrounded by a ₁ B ₁ C ₁ D ₁ from winding start axis Y to a ₁ E ₁ F ₁ D ₁ Is done. Further, the plate-shaped product J, when rotating between the shell spinner and the core, has a large diameter portion 52 and a stepped portion 53.
Since the peripheral velocities of and greatly differ, the stress acting near the boundary between them greatly differs. For this reason, in the flared cone cup product 51, the large-diameter portion 52 and the stepped portion 53 are likely to separate from each other during molding in the shell spinner.

Furthermore, the upper end surface 51a of the flared cone cup product 51
In the roll forming, the plate-shaped product J is lifted up by the action of the stress generated by the difference in the peripheral speed from the large diameter portion 52 to the inverted conical portion 54, and the upper end portion of the large diameter hole of the shell spinner is formed. It is considered that the upper end portion of the plate-shaped product J is brought into contact with the hitting member provided in the above so as to be uniformly aligned. However, in the flared cone cup product 51 produced, since the large diameter portion 52 has a substantially cylindrical shape, the peripheral velocities of this portion are substantially equal, and when the plate-shaped product J is wound between the shell spinner and the core, There is a problem that upward stress is unlikely to act on the large diameter portion 52, and the upper end surface 51a of the flared cone cup product 51 tends to be uneven.

The above-mentioned problem is also the same in the flared cone cup product in which the stepped portion 53 is inclined inward.

[Means for Solving the Problems]

In order to solve the above problems, a flare type cone cup molding die according to the present invention comprises a pair of a shell spinner and a core. The shell spinner includes an inverted conical hole portion and an inverted conical large diameter hole portion. Has a molding die hole consisting of two die holes on the inner peripheral surface, and the inverted conical large diameter die hole has a larger inclination angle of the generatrix with respect to the inverse conical axis line than the inverse conical die hole. The forming die hole is configured such that the large-diameter side end of the above-mentioned reverse conical mold hole is connected to the small-diameter side end of the reverse-conical mold hole having the same diameter as this large-diameter side end. It is formed in a flare shape, and the above-mentioned core is characterized in that it is formed in a reduced similar shape that matches the inner peripheral surface shape of the shell spinner.

[Action]

According to the above configuration, a flared cone cup product is formed by roll forming with a pair of shell spinner and core. At this time, although the inverse cone large diameter type hole portion coupled with the inverse cone type hole portion is formed such that the inclination angle of the generatrix with respect to the axis of the inverse cone shape is larger than that of the inverse cone type hole portion, The curvatures of the inverted conical hole portion and the inverted conical large diameter hole portion are relatively small. Therefore, in the molding process of the flared cone cup product in the shell spinner, the flare-shaped cone cup product has a portion corresponding to the above-mentioned inverted conical hole portion and a portion corresponding to the inverted conical large-diameter hole portion. The situation of separation is suppressed.

Further, the inverted conical large-diameter hole is formed such that the inclination angle of the generatrix with respect to the axis of the inverted conical is larger than that of the inverted conical hole, and the peripheral speed on the opening end side of the inverted-conical large hole is Is higher than the peripheral velocity on the side of the inverted conical hole, so the plate-like product caught in the shell spinner is subjected to stress from the inverted conical hole toward the inverted conical large diameter hole. Then, in the molded flare-shaped cone cup product, the upper end portion, that is, the end surface on the large-diameter side of the inverted conical large-diameter hole portion is uniformly aligned.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 13.

As shown in FIG. 2, the flare-shaped cone cup manufacturing apparatus closed the upper mold 7 with the lower mold 5 after supplying a certain amount of the mixed raw material onto the molding surface 6 of the lower mold 5 of the mold C. In this state, it is transferred into the oven 9 by the transport chain 8, and after exiting the oven 9, the correlative guide function of the opening / closing roller 10 of the upper die 7 and the guide rails 11 and 12 installed in parallel with each other is used. The upper mold 7 is configured to be released from the lower mold 5 again. When the upper mold 7 is opened, the oven 9
The fan-shaped plate-shaped product D fired inside is separated from the smooth molding surface 6 of the lower mold 5 and adheres to and follows the molding surface 14 of the upper mold 7 having the lattice pattern concave groove portions 13. . Therefore, upper mold 7
Of the shell spinner 15 hung at equal intervals under the periphery of the turntable E arranged on the side of the opening transition direction of the
Thus, the plate-shaped product D is peeled off from the upper die molding surface 14 and rolled into the shell spinner 15 for roll molding.

The structure of the shell spinner 15 will be described in detail. As shown in FIGS. 1 and 3 to 7, a product winding opening 16 is vertically provided on one side of the shell spinner 15 having a substantially inverted conical shape. Then, the strip plate-shaped cutter 19 is attached to the inner side surface notch step portion 18 formed in the tangential protrusion 17 of the outer edge thereof, and the blade edge portion of the cutter 19 is inclined at the same inclination angle as the side surface of the shell spinner 15. The shape is slightly projected. Further, at the center upper end of the shell spinner 15, the extruding cylinder shown in FIG.
A stepped opening 21 for fitting an extrusion cylinder for fitting 20 is formed, and under the opening 21, as shown in FIG. 1, for molding the outer peripheral shape of a flared cone cup product. An inverted conical large-diameter hole portion 22 and an inverted conical large-diameter hole portion 23 coupled to the inverted conical large-diameter hole portion 22 are formed.
The molding die hole portion composed of 22, 23 is configured so that the flared cone cup product can be molded into a flared shape. An R having a small curvature may be formed at the boundary between the mold holes 22 and 23.

Reference numeral 25 denotes a product winding core that is concentrically fitted inside the shell spinner 15, and the core 25 and the shell spinner 15 constitute a flare cone cup molding die. The core 25 has a reduced similar outer peripheral surface shape that matches the inner peripheral surface shape of the shell spinner 15, and is configured to be vertically movable and rotatable. That is, as shown in FIG. 3, the elevating body 26 ascends and descends along the guide shafts 27, 28, so that the shaft 29 interlocking with the elevating body 26, the mounting member 30, the extruding cylinder 20, and the core 25.
Is configured to move up and down together with the lifting body 26. Further, when the pulley 31 is rotated, the pulley 31 has a spline structure regardless of the raising / lowering operation of the shaft 29.
Is transmitted to the shaft 29, and the core 25 projecting from the lower end of the shaft 29 rotates integrally. Further, when the cam blower 32 is moved up and down, the extruding cylinder 20 fitted with the outer periphery of the base portion of the core 25 is independently moved up and down so that the flared cone cup product attached to the core 25 can be pushed out from above. Has been done.

Then, between the fitting of the core 25 inside the shell spinner 15 in a fitted state, a molding hole 33 having a substantially conical tubular shape is formed. Reference numeral 34 is a product-engaging locking tooth that is vertically provided on the outer peripheral surface of the inverted conical shape of the core 25.

In the above configuration, when the plate-shaped product D is peeled off, the mold C is traveling straight in the arrow X direction in FIG. 4 by the transport chain 8 while the upper mold 7 shown in FIG. 8 is open. On the other hand, the shell spinner 15 is the turntable E shown in FIG.
Rotation of the upper mold 7 causes the upper mold 7 to turn in the arrow Y direction (FIG. 4) opposite to the traveling direction. Therefore, when the shell spinner 15 comes closest to the upper die 7, the cutting edge portion of the cutter 19 slides on the molding surface 14 of the upper die 7 to peel off the front end portion of the plate-shaped product D, and the turning operation of the shell spinner 15 is performed. Combined with the rectilinear movement of the upper die 7, the peeling of the plate-shaped product D and the subsequent winding operation of the product D into the molding hole 33 inside the shell spinner 15 are continuously performed. And shell spinner
15 When the product D is wound inside, shell spinner
Since the core 25 fitted in the inside of 15 rotates in the clockwise direction integrally with the shaft 29, the plate-like product D is retained by the engagement teeth 34 on the outer peripheral portion of the core 25. Following the rotation of the core 25, the core 25 is inserted into the molding hole 33 and rolled into a roll.

At this time, the plate-shaped product D is formed into the flare-shaped cone cup product 39 shown in FIG.
As shown in FIG. 10, from the winding start axis M to A ₂ B ₂ C ₂ D ₂
The portion indicated by is subjected to the deformation due to the forming indicated by A ₂ E ₂ F ₂ D ₂ and is roll-formed. In this roll forming, as shown in FIG. 11, the difference in curvature between the inverted conical large diameter type hole 22 and the inverted conical type hole 23 of the shell spinner 15, that is, the reverse of the flared cone cup product 39. Since the difference in curvature between the large cone diameter portion 40 and the reverse cone portion 41 is relatively small, it is possible to suppress the separation between the large reverse cone diameter portion 40 and the reverse cone portion 41 due to this difference in curvature. Further, the plate-shaped product D can be easily wound. Therefore, the molding surfaces 6 and 14 of the lower mold 5 and the upper mold 7 shown in FIG. 8 may be flat surfaces.

Furthermore, in the shell spinner 15, the inclination angle of the generatrix of the inverted conical large diameter type hole portion 22 with respect to the center line is the inverted conical type hole portion.
It becomes larger than the inclination angle of 23 busbars, and during molding,
Since the peripheral speed on the opening end side of the inverted conical large-diameter hole 22 is increased, upward stress acts on the plate-shaped product D rotating in the molding hole 33 of the shell spinner 15, and the plate-shaped product D is produced. The upper end of the abutment contacts the lower end of the push-out cylinder 20. As a result, the flared cone cup product 39 is formed in a shape in which the upper end surface 39a is uniformly aligned.

Further, since the flare-shaped corn cup product 39 that has not left the oven 9 is in a high-temperature baked state, when it is wound into the molding hole 33, the inner peripheral surface of the shell spinner 15 and the outer peripheral surface of the core 25. They are fused together by the pressure exerted by.

After that, when the shaft 29 rises, the flared corn cup product 39 moves upward while being attached to the core 25, and is separated from the inside of the shell spinner 15. The downward movement of the cam follower 32 causes the extruding cylinder 20 to descend independently.
Remove the flared corn cup product 39 by pushing down on the upper edge of the 39 to release it from the core 25.
A flared cone cup product 39 of the shape shown in Figures 12 and 13 is obtained.

[Effect of device]

As described above, the flare type cone cup molding die according to the present invention comprises a pair of shell spinner and core, and the shell spinner is composed of an inverted conical hole portion and an inverted conical large diameter hole portion. There is a molding die hole part consisting of two die hole parts on the inner peripheral surface, and the reverse cone large diameter mold hole is set to have a larger inclination angle of the generatrix with respect to the axis of the reverse cone than the reverse cone shape hole part,
The forming die hole is flared by connecting the large-diameter side end of the above-mentioned reverse-conical mold hole with the small-diameter side end of the reverse-cone-shaped hole having the same diameter as this large-diameter side end. The core is formed so as to have a reduced similar shape that matches the shape of the inner peripheral surface of the shell spinner.

Thereby, in the process of forming the flare-shaped cone cup product, it is possible to suppress the problem that the flare-shaped cone cup product is separated, and it is possible to uniformly arrange the upper end surfaces of the flare-shaped cone cup product. Therefore, the product yield can be improved, and a good flare-shaped corn cup product can be obtained.
