In the case of foodstuffs contained in cups such as coffee cups, conventionally, cups are manufactured by cup makers, while foodstuffs such as confectionery makers are manufactured and filled by the foodstuffs themselves as contents. The cups produced by the
It was in a physical distribution form in which the car delivered to the food manufacturer. In addition, since these cups are light in weight relative to their internal volume, the machines and equipment used are all simple, especially in the manufacturing work of confectionery cups that are mass-produced by automatic machines and the transportation work to the confectionery site. , Need to be compact. Therefore, in order to reduce the volume of cups that are handled daily in manufacturing and transportation as much as possible,
The individual pieces are stacked (stacked) as shown in Fig. 21, but this stacking does not take up a work place for confectionery work. 1) If the same number of cups are stacked (height) ) Is as short as possible, 2) At work places such as confectionery sites where food items are filled into the interior of each cup, the cups that are supplied in a stacked state can be quickly combined by using vacuum suction and a gripping device. It is required to reliably extract one piece and automatically separate it.

There are two types of conventional cylindrical barrels for cups for confectionery, drinking water, etc., as shown in the perspective views of FIG. 2 (A) and FIG. 10 (A). Is formed from the fan-shaped paper shown in FIG. 2 (B), polyethylene-laminated paper, plastic sheet, or the like into a cylindrical shape by the method described below.

[Problems to be Solved by the Invention]

As already described as the prior art, stacking also maximizes the weight per transport volume for transportation and confectionery work, and does not take up the area or volume of the work place at the site of cup manufacturing and food manufacturing. 1) If the number of cups is the same, the stacking length (height) is as short as possible. 2) At work places such as confectionery sites where food items are filled inside each cup, they are supplied in a stacked state. It is required to quickly and surely extract one cup from another cup by using vacuum suction and a grasping device and separate them automatically. 3) The cups shown in FIGS. 17 and 19 have a short stacking length, but the outer periphery of the barrel to be stacked next is inserted into the inner periphery of the lower barrel, and the stacks are stacked one after another to 50 to 20.
About 0 pieces are stacked, and there are no gaps between adjacent ones in the many cylinders one after another, so it is difficult to reliably extract and separate one piece due to close contact friction under atmospheric pressure. This will hinder the separation work in. 4) The cup (A ₁ + B ₂ ) type shown in FIG. 17 has the thread bottom 12 because of the side wall B ′ ₂ of the inserted bottom plate B ₂ type and the cup (A ₁ + B ₅ ) type shown in FIG. Therefore, the stacking length cannot be reduced below a certain limit.

5) Further, as described in the section of the manufacturing process in the prior art, a) the number of steps is large, requiring 9 steps, and b) after pressing the bottom plate B ₂ type onto the core metal, In order to wind the barrel on the outer periphery of the core metal and the bottom plate B ₂ type, it is necessary to retract the pressing tool from the contact position with the core metal. At this time, the shallow bottom plate made of paper is The warp or part may be deformed at the position where it is wound around the barrel, and if the barrel is wound around the bottom plate as it is, defects such as foodstuffs leaking from the deformed part will occur, and There is a limit to the speedup due to the required pressing tool and the reciprocal pivoting motion for opening and closing the pair of wings. Also, the use of wings is large for large cups because the wings are large. It may be difficult to improve the production efficiency by speeding up It is difficult to hope for the above. D) In the case of a cone-shaped cup that does not require a bottom plate, such as a cone cup of an ice cream, a guide roll is provided on the peripheral surface of the conical pillar-shaped mandrel roll. And the two are rotated in opposite directions at a high speed, and the work (workpiece) such as the above-mentioned paper or polyethylene paper wound around the roll is supplied between the pair of rolls and attached. A rotary roll method for performing gluing and cutting for each cup by a gluing device and a cutter that have been established is established as a prior art. Since it is indispensable to insert the bottom plate into the inner circumference, it is impossible to form a cup around the outer circumference of the cup using a high-speed rotation roll and wrap it around, and to insert the bottom plate into the inner circumference of the bottom. Moreover, it is necessary to develop a roll-moldable cup. Was desired.

[0009]

In the present invention, a bottom plate is attached to the outer periphery of the bottom of the barrel to separate it from the conventional prejudice to form a product cup, which is so-called a bottom body extrapolation method as opposed to the conventional bottom body insertion method. As a result, 1) the problem of being difficult to extract from the stacking state was solved, and 2) the high speed rotation roll method could also be adopted by the bottom body extrapolation method to solve the above problems. The fan-shaped barrel blank 14a shown in FIGS. 2 (B) and 7 (B) is used without adopting the high-speed rotation roll method of 2) above.
Even if the cup is used as the cup by the molding apparatus of FIG. 3) As a manufacturing method, a cylinder blank (material) formed in a predetermined shape by a high-speed rotation roll method or a press or a cutter is supplied from a roll winding state to a rotating forming roll, and first, After molding the barrel, press the bottom plate against the outside of the small diameter side end of the molding roll to bond the bottom plate to the outside of the barrel, and form a vertical strip having a minute height in the vertical direction of the outer circumference of the side wall of the bottom plate. The above-mentioned problems have been solved by adopting a structure provided with.

[0010]

In the cup according to the present invention, the side wall of the bottom plate is externally inserted on the outer periphery of the bottom of the barrel, and the vertical stripes provided on this side wall are minute (4 mm or less). 1) When the cups are stacked one after another And the entire length of the stacking is shortened by entering deeply into the inner circumference of the cups in front of each other. Since the degree of adhesion between them is remarkably reduced, it is easy to automatically extract and separate the individual pieces. 3) Furthermore, using the work of the barrel as the roll material, it is continuous to the rotating forming roll. It is also possible to supply it to, and a remarkable speed-up is possible.

Due to the diameter difference between the large diameter side and the small diameter side, while rotating with the small diameter side as the inner side of rotation, the ear pick slitters 16 and 17 correspond to the rotation loci of the large diameter side and the small diameter side as shown in FIGS. 5 and 6. The fan-shaped portion that is cut along the two curved lines Ca and Cb and that is sandwiched between these two curved lines becomes the barrel blank 14a for one cup. The blank thus cut off is wrapped around the outer periphery of the molding roll 15 and glued or thermocompressed on the spot, and is pressed by the pressing tool 19 shown in FIGS. 8 (A) and 8 (B) for the bottom plate. The circular blank 20 is pressed against the small-diameter end of the forming roll 15, and the bottom plate B ₂
A mold may be mounted, but a plurality of forming rolls 15 are arranged in a turntable manner with respect to the guide rolls 15 ', and the forming rolls 15 around which the blank is wound are moved to the bottom plate mounting position. Then, as shown in step (f) of FIG. 7, another forming roll 15 may be arranged on the guide roll 15 'to form the next blank. The structure may be selected according to the amount.

Next, the work of mounting the bottom plate will be described. As shown in FIGS. 8A and 8B, a shallow cup-shaped pressing tool 19 that rotates in the same direction as the forming roll 15 at the same speed.
However, the circular blank 20 of the bottom plate is pressed against the small-diameter end portion of the forming roll 15 in the direction of the arrow, and the state shown in FIG. 8B is obtained. At this time, the inner circumference 1 of the side wall 19a of the pressing tool 19
9b is formed with a plurality of vertical strips 13 not shown in FIG. 8A but shown in FIG. 1 in the vertical direction. Next, as shown in FIG. 8C, the pressing tool 19 is retracted, compressed air is blown out from the center hole (not shown) of the forming roll 15, and the formed cup (A ₁ + B ₂ ). The mold is removed from the molding roll 15.

FIG. 7 shows the sequence of continuous molding of the above-mentioned cup by the high-speed rotation roll system. As shown in FIG. 7, the cup of the bottom plate extrapolation method according to the present invention is performed in steps from (a) to (f), and a pair of truncated cone-shaped rolls in which a molding roll 15 and a guide roll 15 'are combined. -It can be rotated at a high speed by sandwiching it between the contact surfaces of the base and molded in one rotation, and it can be molded in 9 steps of (a), (b) and (c) of the bottom plate insertion type cup shown in FIG. 3 steps can be shortened. In FIG. 7, (a) shows a state in which the guide roll 15 'is separated from the contact with the molding roll 15, and (b) shows both rolls.
The barrel blank 14a cut into one cup is bitten into the contact surface by the contact of the rolls, and the barrel blank 14a is part of the outer periphery of the forming roll 15 as the roll rotates in (c). And the roll is rotated once in (d) and the barrel blank 14 is wound.
a is wound around the entire circumference of the forming roll 15, in (e) the guide roll 15 'is separated from the forming roll 15 that has finished winding the barrel blank 14a, and in (f) the outer periphery is a barrel. The molding roll 15 in which the blank 14a is wound is a turntable.
It is moved to the bottom plate mounting position by a bull system or the like, and the next forming roll 15 for winding up the barrel blank 14a is placed at the contact position of the guide roll 15 '. According to this roll system, the three steps (a), (b) and (c) of the conventional bottom plate insertion type shown in FIG. 18 can be omitted. If there is a corrugated projection on the upper end of the barrel, roll molding cannot be used, so use the open / close wing type tool as above. Even if the bottom plate external insertion type cup of the present invention is molded with an open / close wing type tool, the molding speed is slowed but three steps can be similarly omitted.

As a second embodiment according to the present invention, the thread bottom 12

【The invention's effect】

1) In the case of adopting the high-speed rotation roll method, it is not necessary to form the blank of the barrel which has been previously fan-shaped by using press cutting, high-speed cutter, etc., and cups are continuously formed. Since it is mechanically simple, the cup molding cost is significantly reduced. Further, it is possible to continuously form a cup having a large diameter or a length, which is impossible with the conventional wing type (see FIG. 11). 2) Needless to say that the stacking length (height) is reduced, and that the stacking and removal of each individual piece can be easily and reliably carried out by an automatic machine. Sufficient effect can be achieved from the viewpoint of improving production efficiency even if the individual cups are easily and reliably removed by an automatic machine without being used together with. 3) In the case of the conventional bottom plate insertion method, after mounting the bottom plate on the core metal, the barrel is mounted on the outer periphery of the core plate (the bottom plate is inside), so when the bottom plate pressing tool is retracted from the core metal, When the part is partially deformed and it is completed as a cup,
It is possible to eliminate the occurrence of defective products such as foodstuffs leaking out as contents.
