Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a forming apparatus for partition plates used for packaging cylindrical objects such as ampules and lipsticks.

As shown in FIG. 1, there has conventionally been a partition plate for storing ampoules, in which a shape-retaining liner 2 is placed along the back surface of a liner 1 formed into a wavy shape, and the abutting portions of the liner 2 are adhered.

This partition plate makes the upper width dimension of the cylindrical storage part 3 of the liner 1 smaller than the lower inner lining dimension to prevent the ampules stored in this storage part 3 from slipping out upward. As a forming device for such a partition plate, a large number of rollers are movably provided along a quadrilateral track, and a roller alignment groove is provided at a position where the rollers begin to move on a lower horizontal conveyance path of the quadrilateral track. A rotating drum is provided, and a molded liner is supplied to the part of the drum where the roller gill engagement groove and the roller engage, and formed into a wave shape by the rotation of the feed plate and the movement of the roller, and the molded part is held by the roller. There is one in which the material is conveyed to the lower horizontal conveyance path of a quadrilateral track, and during the conveyance, an adhesive is applied to the lower surface of the corrugated portion, and a shape-retaining liner is adhered along the corrugated portion.

However, in the above device, the rollers that hold and convey the wavy formed part of the formed liner are movable independently along quadrilateral tracks, so the rollers that hold the wavy formed part are moved by the tension acting on the formed liner. The spacing between the rollers tends to become uneven, and the height of the partition walls between adjacent rollers becomes uneven due to the movement of the holding rollers in the forming section, and the pitch of the cylindrical storage section becomes uneven, making it difficult to produce a good product. The disadvantage is that it cannot be obtained.

Furthermore, due to the relationship with the tension acting on the molded liner, the production speed cannot be increased, resulting in poor productivity. Therefore, the present invention solves the above-mentioned drawbacks, and makes it possible to efficiently manufacture a good product in which the pitch of the cylindrical storage parts is constant and the height of the partition wall between the storage parts is uniform at extremely high speed. It is an object of the present invention to provide a partition plate forming device that enables the forming of partition plates.

The drums are made to drum one by one, and a molded liner is supplied to the joint part, and the rod-shaped body and the shaping roller are used to form the primary wave shape into a wave shape. As the rods move along the shaped guide section, the distance between the adjacent rods narrows, thereby forming the above-mentioned molded section. An adhesive is applied to the surface of the second-formed section, and a shape-retaining agent is applied to the applied section. The liner is glued along the liner. An embodiment of the present invention will be described below with reference to the accompanying drawings.

The skewing roller 24, which is supported at both ends, is configured so that its convex guide portion fits between the rod-shaped bodies 11 that move. The cam plate 25 is a guide means for limiting the amount of movement of the skewing roller 24, and may be a grooved cam plate having cam grooves for guiding both ends of the skewing roller. The shape of the convex guide portion of the trackway may be any other convex shape that increases the interval pitch of the rod-shaped body 1, and the shape of the arcuate surface 26 provided in a corresponding manner is as follows. <Another concave shape that allows the embedding rollers to be fitted one by one between the rod-shaped bodies 11 with a large interval pitch, and at least one skewed roller 24 to be supported at all times between the bar-shaped bodies 11. But that's fine.

The molded liner A is guided by a guide roller 27 and is supplied from there to a portion of the connecting body 10 where the rod-shaped body 11 and the shaping roller 24 engage.

This molded liner A is primarily formed into a wave shape by the engagement of the rod-shaped body 11 of the connecting body 10 and the shaping roller 24,
The formed part is supported by the rod-shaped body 11 of the coupling body 10 by the movement of the coupling body 10 and the rotation of the rotary drum 19, and the lower part of the suction box 15 (hereinafter referred to as the linear guide section of the trackway) transported to. As a holding means, a suction hole 28 is formed in the portion of the suction pox 15 from the middle of the arc to the bottom wall, and the suction force acting on the suction hole 28 causes the wave-formed portion of the molded liner A to move inward. This prevents the molded portion from coming off the outer periphery of the rod-shaped body 11 even after the suction and shaping rollers 24 are separated.

A device 29 for applying adhesive to the surface of the corrugated portion of the liner A supported by the rod-shaped body 11 of the connecting body 10 is provided in the linear guide section of the trackway, and a device 29 is provided at the rear of the bracket device 29. A support plate 30 is arranged.

Note that vinyl acetate adhesive, hot melt adhesive, etc. can be used as the adhesive to be applied to the waveform forming part. If the former adhesive is used, the support plate 3 and the heater should be used. Install it and heat it.

A guide means 40 is provided downstream of the support plate 30 for forcibly moving the tips of the two liners A and B bonded together downward.

A pair of guide plates 41 are provided in parallel at intervals corresponding to the width dimension of the molded liner A, and the lower surface of the guide plates 41 guides the movement of both sides of the upper surface of the shape-retaining liner B. It looks like this. Note that the guide plate 41
A feed roller 42 is provided below the feed roller 42, and this feed roller 42 is rotated in the direction of the arrow in FIG.
The shape-retaining liner B may be forcibly pulled by utilizing the rotation of the shape-retaining liner B.

The apparatus shown in the embodiment has the above-mentioned structure, and its operation will be explained next.

Now, when the drive sprocket 16 is rotated, the connecting body 1
0 moves in the direction of the arrow in FIG. 2, and when the rod-like bodies 11 of this connecting body 10 move on the convex guide portion of the trackway, the interval between adjacent rod-like bodies 11 becomes wider, and the cam plate 25 Since the skewing rollers 24, both ends of which are supported by arcuate surfaces 26, are adjacent to each other, the movement of the connecting body 10 causes the rotary drum 19 to rotate in the direction of the arrow in FIG.

In the above operating state, the rod-shaped body 1 of the connecting body 10
1 and the shaping roller 24, a molded liner A is placed at the joint part.
When the liner A is supplied, the liner A is primarily formed into a wavy shape by the shaping rollers 24 which are returned between the adjacent rod-like bodies 11 of the connecting body 10.

When the embedding loaf 24 for which the liner A is primarily formed moves to a position where it is removed from the end of the arcuate surface 26 by the rotation of the rotating drum 19, the embedding roller 24 is removed from between the adjacent rod-shaped bodies 11, and the liner A is removed. The primary formed portion is supported by the rod-shaped body 11 of the connecting body 10 and is conveyed toward the linear guide portion of the trackway. At this time, since a suction force acts on the suction hole 28 of the suction box i5 and sucks the primary molded part of the liner A inward, the primary molded part does not come loose from the rod-shaped body 11 of the connecting body 10. It is transported to the linear guide section in a molded state.
When the rod-shaped body 11 of the connecting body 10 reaches from the convex guide portion to the linear guide portion, the adjacent ridges 1 approach each other, so that the primary formed portion becomes secondary due to the approach of the rod-shaped body turtles 1. As shown in FIG. 4, the sides of the semicircular portion of the portion formed by the shaping rollers 24 extend inward with respect to the imaginary perpendicular line passing through both sides of the rod-shaped body 11. As shown in FIG.

When this tertiary formed part is moved to the attachment position of the applicator 29, adhesive is applied to a part of the lower surface of the part that wraps around the lower outer periphery of the rod-shaped weight 1. When you reach the position 30, the above support plate 30
The liner A and the shape-retaining liner B, which are formed in a wavy manner, adhere to each other in the overlapping part, forming a continuous body of partition plates as shown in Figure 1. be done.

When the tip of this continuous body passes through the end of the support plate and advances to the position of the guide plate Kametomi, both sides of the upper surface of the shape-retaining liner B are guided by the lower surface of the guide plate 41, so that the connecting body force Q The molded part supported by the rod-shaped body 11 is detached from the rod-shaped body, and the partition plate continuous body is taken out downward. In addition, the manufactured partition plate continuous body is cut into a required length in the next step, and this is used as a product. As shown in FIG. 1, the scorer 4
3, and by this scorer 43
By forming crease lines on both sides of the ampule and overlapping and gluing the wave-shaped portions of the molded liner A between the crease lines, as shown in FIG.
A partition plate with a number 4 can be formed. The height of the partitioning portion of the support plate can be changed by changing the amount of iron applied by the shaping rollers 24 between the adjacent rod-like bodies 11.

Furthermore, by changing the connecting pitch of the rod-shaped bodies in the continuous body, the waveform shape of the support plate can be changed. If the punched holes are made to resemble, for example, Western liquor bottles, the corresponding articles can be stored in the punched holes after the molding.

As described above, according to the present invention, the shaping rollers that rotate together with the rotating drum are sequentially engaged one by one between the rod-like bodies of the connecting body that moves along the convex guide portion of the trackway, and the engaged portions Since the molded liner is supplied, the molded liner bends along the outer periphery of the rod-shaped body of the connecting body and the outer periphery of the shaping roller, so that the molded liner can be neatly molded.

Further, the connecting body is an endless structure in which one end of the link is connected to both ends of the rod-shaped body, and protrusions protruding laterally from both sides of the other end of the link are connected to each other and arranged outside the rod-shaped body. Therefore, the rod-like bodies of the connecting body that hold the primary formed portion of the molded liner and reach the linear guide portion of the trackway are brought close to each other and held at a predetermined interval by the links. Therefore, the part formed by the shaping roller and the rod-like body can be accurately secondary-formed into the desired shape, and the rod-like bodies are connected to each other by links. Since at least one of the brining rollers that is passed through the rollers presses against the rod-shaped body of the connecting body, the contact resistance between the molded liner and the rod-shaped body is large, and the molded part of the liner is likely to be deformed by the tension acting on the molded liner. Therefore, by applying adhesive to the surface of the molded part of the molded liner and placing the shape-retaining liner along that part, the pitch of the cylindrical object storage parts can be kept constant and the pitch between the storage parts can be prevented. It is possible to obtain a good product with a uniform height of the partition wall part, and also to increase the production speed and manufacture efficiently. Since a holding means for adsorbing the molded liner to the outer periphery of the connecting body is provided, the part formed by the shaping roller and the rod-shaped body may come off from between adjacent rod-shaped bodies, or the part along the outer periphery of the rod-shaped body may It can prevent the liner from coming loose from the rod-shaped body and improve the molding effect of the liner.
