Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is directed to an apparatus for manufacturing badges worn as accessories on clothing, etc. When molding the front material of the badges, a sleeve that is vertically movably fitted onto the upper mold is inserted into the upper mold. The present invention relates to an improvement in a switching mechanism that is fixed at a position protruding from the lower end of the sleeve, and that releases the fixation of the sleeve and allows the sleeve to move upward when a backing material is integrated with a front material.

[Conventional technology]

Equipment for producing badges has been used for a long time, consisting of an upper mold that can move up and down, and left and right lower molds that are selectively moved directly below the upper mold to perform molding together with the upper mold. There is.

To manufacture badges using this device, first, cover the badge cover material over one of the lower molds, fit the surface decorative paper of the cover material into the sleeve fitted over the lower mold, and then fit the cover material onto the upper mold. After fixing the sleeve protruding from the lower end of the upper die, the upper die is moved downward to cover the surface of the cover material with the decorative paper using these upper and lower dies, and at the same time coat the decorative paper. The facing material is pushed into the sleeve of the upper mold and transferred, and then the other lower mold with the badge backing material placed directly below the upper mold is positioned, and the sleeve of the upper mold is released and the top and bottom are moved. By crimping the mold, the outer periphery of the backing material is integrally wrapped with the outer periphery of the front material covered with decorative paper by pushing out the front material with the upper mold while letting the sleeve escape upward.

In such a badge manufacturing device, the switching mechanism for fixing and releasing the upper die sleeve has conventionally been provided by using a mechanism that extends horizontally on the upper surface of the upper die sleeve, as described in Japanese Patent Publication No. 61-32005, for example. The base end of a rotating bar-shaped switching member is rotatably pivoted, while two posts are erected on a horizontal rotating plate to which the left and right lower molds are attached, and the upper ends of these posts are connected to the switching member. When the horizontal rotating plate is rotated in one direction, the switching member is rotated by one post, and the proximal end of the switching member is detached from the upper surface of the upper die sleeve. It is known that when the horizontal rotating plate is rotated in the other direction, the switching member is rotated in the opposite direction by the other post and is locked to the upper surface of the upper die sleeve.

[Problem to be solved by the invention]

However, according to such a switching mechanism,
Two posts are set up on the horizontal rotating plate on which the left and right lower molds are placed, so these posts are used to attach the badge cover material, decorative paper, and backing material to the left and right lower molds, respectively. This results in a decrease in work efficiency when manufacturing a large number of badges. This inconvenience also occurs due to the switching member, which projects horizontally above the lower mold, and seriously impedes smooth work.

Furthermore, although the badge manufacturing device is relatively compact, erecting two posts on the horizontal rotating plate requires making the horizontal rotating plate large. Moreover, the switching member is rotated via these posts in conjunction with the horizontal rotation plate, so that the horizontal rotation plate selectively faces the left and right lower molds relative to the upper mold. There is a problem in that the rotation of the switching member relative to the upper sleeve must be accurately synchronized, which complicates the structure.

The present invention provides an operation switching mechanism for an upper mold sleeve in a badge manufacturing apparatus, which aims to completely eliminate such problems.

[Means to solve the problem]

In order to achieve the above object, the operation switching mechanism of the upper die sleeve in the badge manufacturing apparatus of the present invention is as follows:
In a badge manufacturing device consisting of an upper mold that can be moved up and down, and left and right lower molds that are selectively moved directly below the upper mold to form the badge material together with the upper mold,
An upper mold mounting plate is integrally provided on the upper part of the upper mold, and a lower end thereof protrudes downward from the lower end of the sleeve fitted onto the upper mold and is engaged with the sleeve on the inner surface thereof. The upper end of a locking fitting provided with a locking stepped surface for fixing the sleeve in a state in which it projects downward from the upper mold is rotatably pivoted, and the sleeve fitted into the other lower mold is The outer peripheral diameter of the upper end is formed to be large, and the lower end surface of the locking fitting is brought into sliding contact with the upper end surface, and the locking fitting is rotated outward to move the locking stepped surface away from the upper end surface of the upper die sleeve. It is configured to be spaced apart.

[Effect]

In normal conditions, the sleeve of the upper mold is held at its upper surface by a locking step surface of a locking metal fitting pivotally connected to the upper mold mounting plate so as not to be able to move upward, and is held in a state protruding from the lower end of the upper mold. ing.

If this upper die is moved downward and pressed against the lower die, which has the badge cover material and the cover decorative paper arranged in a polymerized state, these upper and lower dies will integrally apply the decorative paper to the badge cover material. The surface material covered with decorative paper is held in a fitted state within the sleeve of the upper mold.

Next, after separating the upper mold upward, the other lower mold on which the backing material is placed is positioned below the upper mold, and when the upper mold is moved down again, the upper mold sleeve is attached to the lower mold sleeve. Immediately before the pressure contact, the lower end of the locking fitting comes into contact with the upper end outer circumferential surface of the large-diameter lower sleeve, and the locking fitting rotates outward along the outer circumferential surface, and the locking step surface is brought into contact with the upper sleeve. to separate from Therefore, the sleeve can be moved upward, and while the sleeve is released upward, the upper mold extrudes the front material and wraps the outer peripheral edge of the backing material placed on the upper mold on the outer peripheral edge of the front material covered with decorative paper. It is something that unifies them.

〔Example〕

Embodiments of the present invention will be explained with reference to the drawings: 1
is an upper mold integrally formed on the lower surface of the mounting board 2, and a sleeve 3 is fitted onto the outer peripheral surface of the upper mold so as to be able to slide vertically. It is guided by vertical grooves 23 provided on both sides of the outer periphery of the upper mold 1 to enable the above-mentioned vertical sliding, and is maintained in a state in which it protrudes downward by a predetermined length from the lower end of the upper mold 1. By forming the upper half of the sleeve 3 to have a small diameter, an upward annular locking surface 4 is formed at the center of the outer peripheral surface.

Further, the mounting plate 2 on which the upper mold 1 is integrally mounted has a larger diameter than the upper mold 1 and is formed approximately equal to the outer diameter of the lower end of the sleeve 3 having a locking surface 4 at the upper end, A pair of locking fittings 5 are provided at the front and rear of the outer circumference.
The upper end of 5 is rotatably pivoted in the radial direction, and is suspended toward the lower end.

This locking metal fitting 5 has a lower inner surface cut out by an appropriate width to form a downward locking step surface 6 on the upper end thereof which engages in contact with the locking surface 4 of the sleeve 3. , the lower end of the sleeve 3 is made to protrude downward by an appropriate length relative to the lower end of the sleeve 3.

Further, the mounting plate 2 to which the locking metal fitting 5 is pivotally mounted is equipped with a coil spring 7 that constantly presses the inner surface of the upper end of the locking metal fitting 5, and the pressing force of the coil spring 7 causes the locking metal fitting 5 to is urged inward, and its lower end inner surface is brought into contact with the outer periphery of the lower half of the sleeve 3 to hold the locking step surface 6 in a locked state with the locking surface 4 of the sleeve 3.

Reference numerals 8 and 9 denote left and right lower molds disposed on both sides of the upper surface of the horizontal rotating plate 10, and the outer diameter of the cylindrical sleeve 11 fitted into one of the lower molds 8 is the outer diameter of the lower half of the upper mold sleeve 3. The diameter of the locking metal fitting 5 is equal to or slightly smaller than that of the sleeve 11 so that the lower end surface of the locking metal fitting 5 does not come into contact with the upper end surface of the sleeve 11. The half portion is formed to have a larger diameter than the outer diameter of the upper die sleeve 3, and the upper end surface is formed into a guide surface 13 that is inclined diagonally downward in a convex arc shape from the inner circumferential side to the outer circumferential side.

As is well known, these lower mold sleeves 11 and 12 have their upper ends protruding from the lower molds 8 and 9 by a certain distance, and the inner peripheral surface of the upper end of one of the lower mold sleeves 11 is provided with a surface material a. It forms an annular stepped peripheral surface 11a on which the outer peripheral surface of the decorative paper b is placed, and a facing material a is formed on the inner peripheral surface of the upper end of the other lower mold sleeve 12.
A molded inclined surface 12a is formed at the bent peripheral edge of the groove. Further, horizontal flanges 11b and 12b are integrally provided around the lower ends of the lower molds 8 and 9, and these flange parts 11b and 12b and the lower mold sleeves 11 and 12 are integrally provided.
Springs 14 and 15 are press-fitted into several positions between the lower end faces of the lower mold sleeves 11 and 12 to elastically support the lower mold sleeves 11 and 12, respectively.

The horizontal rotating plate 10 has its central portion pivotally attached to the front upper surface of the machine base 16 so as to be able to freely rotate back and forth.A frame 17 is integrally erected on the rear upper surface of the machine base 16. A vertical cylindrical portion 18 is integrally formed on the front surface of the upper end, and a rod 19 is constantly pressed upward by a spring (not shown) inside the vertical cylindrical portion.
The lower end of the rod 18 is integrally fixed to the center of the upper surface of the upper die mounting plate 2 by vertically slidingly inserting the rod 18.

Reference numeral 20 denotes an operation handle pivotably mounted on the upper end of the vertical cylinder 18 so as to be able to move up and down. The rod 18 is configured to be moved downward via the cam plate portion 21 by vertical movement of the rod 18.

In order to manufacture badges using the badge manufacturing apparatus having the operation switching mechanism for the upper mold sleeve configured as described above, first, the horizontal rotating plate 10 is rotated to move one lower mold 8 from below the upper mold to one side. The badge cover material a is placed on the upper surface of the lower mold 8, and the downwardly bent outer peripheral edge of the cover material a is placed in the gap between the outer peripheral surface of the upper end of the lower mold and the inner peripheral surface of the sleeve 11. After inserting the sleeve 11, a circular decorative paper with appropriate patterns, designs, characters, etc. printed on its surface, or a decorative paper b prepared by cutting a photograph or the like into a circular shape is placed on the step peripheral surface 11a of the sleeve 11. The horizontal rotating plate 10 is rotated in the opposite direction to position the lower mold 8 directly below the upper mold 1.

Next, when the handle 20 is pushed down, the rod 19 is moved downward by the cam plate portion 21, and the upper die mounting plate 2, which is integrally fixed to the lower end of the rod, is moved downward and the lower end surface of the upper die sleeve 3 is moved downward. It is brought into contact with the upper end surface of the lower die sleeve 11 (see FIG. 3).

At this time, the locking metal fitting 5 attached to the mounting board 2,
5 moves its inner surface downward along the outer peripheral surface of the sleeve 11 without coming into contact with the lower mold sleeve 11, and the locking fittings 5, 5 are attached to the locking surface 4 of the upper mold sleeve 3. The locking step surface 6 is held in a locked state, and the lower half of the upper mold sleeve 3 is projected from the lower end of the upper mold 1, thereby preventing upward movement.

When the upper die 1 is further moved downward from the state where the upper die sleeve 3 and the lower die sleeve 11 are in contact with each other, the lower die sleeve 11 is pressed by the upper die sleeve 3 and the spring 14 is pressed. The lower die 8 moves downward against the force and enters the upper die sleeve 3, and these upper and lower dies 1 and 8 polymerize the decorative paper b on the surface of the facing material a and also remove the peripheral edge of the decorative paper b. is bent downward along the inner peripheral surface of the upper die sleeve 3.

Thereafter, when the pressing force on the handle 20 is released and the handle 20 is returned to its original position, the cover material a covered with the decorative paper b is lifted by the frictional force between the decorative paper b and the upper sleeve 3. It is transferred while being fitted into the mold sleeve 3.

Next, a disc-shaped backing material c whose outer peripheral edge is bent upward is placed on the other lower mold 9, and then the horizontal rotating plate 10 is rotated to transfer the lower mold 9 to the upper mold. 1 (see Figure 5).

When the upper die 1 is moved downward from this state by operating the handle in the same manner as described above, the lower end surfaces of the locking fittings 5, 5 are moved to the lower die before the upper die sleeve 3 comes into contact with the sleeve 12 of the lower die 9. The upper end guide surface 13 of the sleeve 12 comes into contact with the guide surface 13, and the locking fitting 5
is rotated outward against the force of the spring 7, and its locking step surface 6 is aligned with the locking surface 4 of the upper mold sleeve 3.
The upper movement restriction of the sleeve 3 is released by moving away from the sleeve 3, and the inner surface of the tip end of the locking metal fitting 5 touches the lower sleeve 12.
The released state is maintained by slidingly contacting the outer circumferential surface of (see Fig. 6).

Immediately after the upper mold sleeve 3 is released, the lower end surface of the upper mold sleeve 3 comes into contact with the upper end surface of the lower mold sleeve 12, and when the upper mold 1 is further moved downward,
With the upper mold sleeve 3 in contact with the lower mold sleeve 12, only the upper mold 1 moves downward, as shown in FIG.
The decorative paper covering material a fitted in the upper mold sleeve 3 is pushed down toward the lower mold 9 side, and the outer peripheral edge of the decorative paper b is bent inward by the forming slope 12 a of the lower mold sleeve 12. At the same time, the outer circumferential edge of the backing material c is fitted into the bent inner circumferential surface, and the upper and lower dies 1 and 9 are used to press and integrate them to form a badge.

Then, when the upper die 1 is moved upward, the locking fittings 5 and 5 are first pulled up together, and then the upper die sleeve 12 is moved upward and the locking fitting 5 is engaged with the locking surface 4. The stop surface 6 is locked and the next batch is ready to be manufactured, while the manufactured badge is taken out from the lower die 9 and the above operation is performed again to manufacture the badge.

In addition, in the above embodiment, the lower mold sleeve 12 is used as a structure for rotating the locking metal fitting 5 outward.
Although the upper end surface is formed into an arc-shaped guide surface 13, such a guide surface is not formed on the upper end surface of the lower die sleeve 12, and the inner part of the lower end surface of the locking fitting 5 is formed into an arc-shaped guide surface. Even if it is formed, the same effect as described above can be achieved.

〔Effect of the invention〕

As described above, according to the upper mold sleeve operation switching mechanism of the present invention, there is one upper mold that is movable up and down, and the badge material is molded together with the upper mold by selectively moving it directly below the upper mold. In a badge manufacturing apparatus consisting of left and right lower molds, an upper mold mounting board is integrally provided on the upper part of the upper mold, and the lower end is located downward from the lower end of the sleeve fitted on the upper mold on both sides of the upper mold mounting board. The upper end of a locking fitting is rotatably pivoted, the locking fitting having a locking stepped surface protruding from the inner surface and locking onto the sleeve to fix the sleeve in a state in which it projects downward from the upper die; The outer peripheral diameter of the upper end of the sleeve fitted into the other lower mold is formed to a large diameter, and the lower end surface of the locking metal fitting is brought into sliding contact with the upper end surface of the sleeve, and the locking metal fitting is rotated outward. Since the stop surface is configured to be spaced apart from the upper end surface of the upper die sleeve, the upper die sleeve is fixed by a locking metal fitting attached to the upper die mounting board, and the upper die sleeve is fixed. The fixing is released by bringing the lower end of the locking metal fitting into contact with the upper end surface of the other lower mold sleeve, so the structure is simple and there are no obstacles around the left and right lower molds that would get in the way of work. It is possible to create an environment completely free of any existing molds, so that the work of attaching badge face materials and backing materials to the left and right lower molds can be done quickly without any hindrance, and work efficiency can be significantly improved. It is.

In addition, the upper die sleeve can be reliably held in place by the locking step surface of the locking fitting in a normal state without being able to move upward, and the upper die sleeve can be held securely in place when the badge face material and backing material are integrated. Since the structure is such that the fixation of the upper mold sleeve by the locking metal fitting is released only when the lower mold moves downward, the operation is performed completely independently of the rotation of the horizontal rotating plate on which the left and right lower molds are arranged. This allows the horizontal rotation plate to be rotated smoothly.
