Abstract

PURPOSE:To permit mass-production of straws with spoons by a method in which the tips of straws are cut into a form of folded spoon, and the crushed tips of the straws are opened by an opener and heat-shrunk. CONSTITUTION:A polypropylene straw S is placed on a flap base 16', and the tip of the straw S is cut into a form of folded spoon by a cutter consisting of a male blade 11 and a female blade 14. The crushed tip of the straw S is pressed and widened by a conical opener, a presser part 19 is lowered onto the cut spoon portion, and the spoon portion is heated by a hot plate 23 for thermal shrinkage to form a spoon 3. The mass-production of straws with spoons suitable for eating broken ice, shebet, etc., is made possible.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for manufacturing a straw with a spoon, the tip of which is integrally formed into a spoon shape.

A straw with a spoon consists of a cylindrical straw part and a spoon part at the tip.The straw part can be used for drinking, and the spoon part can be used to stir or scoop shaved ice, ice cream, or sherbet. It is something that can be done.

To manufacture a straw with a spoon, a flexible cylindrical straw member made of synthetic resin is used, but since the straw member is cylindrical and has flexibility,
Molding was extremely difficult and mass production was not possible.

This invention uses a heat-shrinkable synthetic resin strut member, and cuts the tip of the strut member into a shape in which the spoon portion □ is folded with the longitudinal center line of the bottom of the spoon portion as the axis of symmetry. After opening this folded part, the opening part is pressed onto a hot plate, the bottom of the opening part is heat-shrinked, and the spoon part is formed in a continuous operation, thereby producing a straw with a spoon in an extremely efficient manner. The purpose is to

Hereinafter, the present invention will be described in detail based on illustrated embodiments.

First, the straw with spoon (1) will be explained with reference to Figures 1 to 5. (2) is a part of the straw, and (3)
is a spoon portion formed integrally with the straw portion at the tip of the straw portion (2). This straw with spoon
(1) is formed of a cylindrical stroke member made of polypropylene that is heat-shrinkable, flexible, and has moderate strength. This is because the spoon portion is brought into contact with the bottom of a spoon or spoon that requires flexibility to suck in liquid or scoop ice cream or the like.

To explain the manufacturing device for this straw with spoon (1), in FIGS. 6 to 11, (4) is!
, (5) is a control box, and (6) is a hopper that accommodates the straw members. (7) is a cylinder for injecting stroke parts, which injects stroke parts one by one.

(8) is a supply plate, which is provided with a guide groove (9) in the longitudinal direction, and as shown in FIG. A hot plate (ha)
It is sent so that the tip is located at the second position.

00 is a stand for mounting a male blade, which has a male blade 0) whose position can be adjusted, and moves from the cylinder 02 in a direction perpendicular to the stroke member.

Reference numeral 03 is a stand on which the female blade is attached, and has a female blade 04 whose position can be adjusted, and moves from the cylinder in a direction perpendicular to the stroke member.

Here, a male blade (11) and a female blade 04) are provided facing each other.
To explain the shape of the spoon part (3), as shown in Figs. 9 and 10, the double-edged blades 01) and 04)
They are each formed symmetrically into a shape obtained by folding the bottom longitudinal direction center line (L-L) as an axis of symmetry, that is, a shape shown in FIG. 13. Note that the female blade α→ moves back when the male blade L1 contacts the guide member OQ, thereby sharpening the cut of the stroke member (FIG. 11). (16') is a scoop plate of the stroke member.

Note that 07) and Q7) are guide shafts for moving the base 00 for attaching the male blade and for moving the base 03 for attaching the female blade.

The α frame is a support plate that vertically suspends the opening member (A) driven by the silicone rubber holding member 01 and the cylinder eA)K, and is moved up and down by the cylinder (A), cam device, crank device, etc. (Figure 7).

This holding member 0 Samurai is attached to the support plate (c) so that its position can be adjusted via the attachment member. A material with low thermal conductivity is used, but if metal is used, a water cooling device should be provided.

The aperture member (a) is a substantially triangular plate with a domed tip as shown in Fig. 8, and the aperture member is cut into a strut member after being cut with a male blade and a female blade. Insert it into the folded part of the tip and open the folded part (14th
Fig. 15).

The canopy is a hot plate with a built-in heater, and is provided on a base (4) directly below the holding member 00.

Based on the above configuration, the present invention has the following operations and effects.

As shown in FIG. 7, the straw member (S) supplied from the hopper (6) has its tip located above the hot plate (C). At this time, the holding member a is located near the tip. As shown in FIG. 12, by the operation of the cylinders 02 and θ, the male blade 01) and the female blade 0→ move from both sides of the tip of the stroke member (S) in a pinching manner, and the guide member 0
The scoop plate (16') of Q scoops the tip and cuts the tip with both blades. The cut tip is formed into a shape as shown in FIG.

Then, the male blade 01) and female blade 04) move back, and the cylinder (
By the operation of (a), the support plate (to) descends, and the holding member 0 Samurai lightly presses the tip, making it easier to open the opening.
The opening member (A) is inserted into the folded portion, and the tip is opened (Fig. 4, Fig. 15).

After opening the folded portion, the presser member 01 rises slightly, and the opening member (a) retreats, and the presser member 0[
The opening part is pressed against the hot plate (c), and the bottom surface of the opening part is heat-shrinked to form the shape shown in FIGS. 1 to 3, that is, the spoon part (3).

When the spoon part (3) is formed, the holding member 0@ rises, and then it is pushed out by the stroke member supplied by the supply plate (8) and sent onto the conveyor (c).

In addition, in the example, the weight of one stroke member (S) is approximately 1 cm, the outer diameter is 1tio, eyxy, and the thickness is 0.2ff.
ff, the humidity of the hot plate (c) is below 150'Q, about 140
Around 'c, the time required for molding is P! It takes about 0.5 seconds.

Of course, the temperature of the hot plate varies depending on conditions Q such as the material of the stroke member, its thickness, and room temperature.

As explained above, the present invention makes it possible to mass-produce straws with spoons, which has been extremely difficult in the past.
