Abstract

PURPOSE:To cut a covering film while keeping the surface of a dough smooth by making one sliding surface of a square unit a convex shape and the other sliding surface a concave shape and combining the square units so that the above-mentioned convex-or concave-shaped sliding surface may be slidable on the concave- or convex- shaped sliding surface of another square unit adjacent thereto. CONSTITUTION:Three or more square units 1 having two or more sliding surfaces 2 and 3 are mutually slidably assembled so as to form an enclosed part 5 at the central part surrounded thereby and a covering film of a dough 6 passing through the enclosed part 5 is cut by opening and closing the enclosed part 5. In the above square unit 1, one sliding surface 2 is made a convex shape and the other sliding surface 3 is made a concave shape so that the concave- and convex-shaped sliding surfaces 2 or 3 may be slidable on the convex- and concave-shaped surfaces 3 and 2 of another square units 1 adjacent thereto. The covering film can, as the result, be cut in a state where the content material is thoroughly covered while keeping the surface of the dough smooth without generation of a flower-like pattern unlike in the conventional method. In addition, a continuous operation is possible without occurrence of adhesion of the dough and a highquality product can be provided.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to the production of foods such as manju buns and ohagi, in which an inner packaging material is wrapped in an outer skin material. Since the continuous confectionery dough can be cut without exposing the center filling and with a smooth surface, it can be used to produce various types of confectionery such as steamed buns, and has a great effect on improving product quality.

(Prior Art) There are various wrapping cutting methods for creating a wrapping structure like a bun from a material with a double inner and outer structure supplied in a continuous rod-shaped body. 1986-
No. 6925, No. 61-27587, etc., and these conventional techniques can cut the inner wrapping material without exposing it, but when cutting the rod-shaped dough, unevenness such as flower patterns may occur on the surface of the dough. If the surface of the outer skin is to be flattened and smooth, it is necessary to manually or otherwise touch up the surface, resulting in extra labor.

(Means for Solving the Problems) The present invention solves these drawbacks, and has a structure in which at least three rectangular pieces having at least two sliding surfaces are assembled so as to be slidable with respect to each other. In a device that forms an enclosure in the center and opens and closes the enclosure to cover and cut the fabric passing through the enclosure, one sliding surface of the square piece is formed in a convex shape and the other sliding surface is formed in a concave shape. However, the convex and concave sliding surfaces are in a sliding relationship with the concave and convex sliding surfaces of adjacent square pieces, respectively, so that the surroundings formed by the structure of the present invention are mutually connected. The abutment part of the square piece is different from the conventional shape because it has no steps and has a surface that is smooth even when the square piece slides and the enclosure closes.
When cutting the envelope, the outer skin is not pinched by the steps and the outer skin is not picked up, so no folds are formed in the product.

In addition, in the closure operation of the enclosure, the rectangular pieces gather together, and the depression that is created when the enclosure is closed decreases and disappears over time, making it possible to cut easily sticky fabrics and highly elastic materials without any problems. became possible.

(Example) The present invention will be described below based on an example. Reference numeral 1 indicates a square piece having a thickness a, and numerals 2 and 3 indicate sliding surfaces on adjacent sides of the square piece l.

The sliding surface 2 has an upper surface 21, a middle surface 22, and a lower surface 23, forming a convex surface as a whole.

Further, the sliding surface 3 has an upper surface 31, a middle surface 32, and a lower surface 33 so as to form a concave surface.

Combine at least three of these square pieces, - square piece 1
The convex sliding surface 2 of the square piece 1 and the concave sliding surface of the adjacent square piece 1 engage with each other.

A cutout 24 is provided at the outer end of the convex sliding surface 2.

As shown in FIG. 2, square pieces l of the same shape are assembled, and a box 5 is formed in the center of this assembly 4.

In this embodiment, the rectangular piece 1 is explained using six assemblies 4, but the number is not limited to six, and the enclosure can be formed as long as three or more assemblies are used. Target is 6
From 1 to 12 pieces is appropriate.

A portion facing the periphery of the enclosure 5 is constituted by a sliding surface 2, which serves as a surface for pressing the rod-shaped fabric passing through this enclosure.

As shown in FIG. 3, reference numeral 6 denotes a continuous rod-shaped dough that is fed so as to pass through the enclosure 5, and has an inner wrapping material 7 concentrically formed therein.

3 to 5 show the state in which the enclosure 5 is opened and closed by sliding the rectangular piece l of the assembly 4 housed in the housing 10 in the direction of the arrow.

The square piece 1 slides in the direction of the arrow, and the box 5 becomes smaller. Eventually, as shown in FIG. 4, the tangents 221 gather in one place and the box disappears, and at this time it is surrounded by tangents 211 and 231. Depressions 61 are formed on the top and bottom, but as the sliding progresses further, as shown in Fig. 5 (the depressions 61 also disappear and the contacts 212 gather,
There will only be a flat surface.

In the present invention, since the cutout 24 is provided at the outer end of the convex sliding surface 2, the cutout 24 is provided on the inner surface 101 of the housing.
When the grooves 61 are slid until they come into contact with each other, the depressions 61 are reduced and disappear.

When the square piece is moved in the opposite direction of the arrow, a box 5 appears.

By opening and closing this enclosure 5, the rod-shaped fabric 6 having the supplied inner wrapping material is wrapped and cut, and according to this configuration, the cut surface is smoothly cut without any folds. A cutting effect is created.

As shown in FIG. 7, the thickness a of the generatrix contact surface of the middle surface 22 that first contacts the fabric 61 is selected depending on the properties of the fabric, and it contacts the fabric with a predetermined thickness and remains as it is. Move to the center of box 5 using a.

At this time, the outer skin 6 is moved to the center, and the inner packaging material 7
flows in the direction of arrow m.

When the tangent lines 221 come together, the moved fabric is separated above and below the tangent line 221 to form upper and lower fabrics, which can completely cover the inner wrapping material 7.

At this time, when the upper surface 21 and the lower surface 23 forming the non-acute convex sliding surface 2 enter the axis of the fabric 6, the upper surface 2
1 and the lower surface 23 move the fabric by a predetermined amount to the center, and the surface area of the constriction created by pressure from the circumferential direction of the fabric decreases, so it is possible to cut without thinning the outer skin 6 or exposing the inner wrapping material 7. I can do it.

In addition, since the concave sliding surface 3 engages with the convex sliding surface 2, there are no grooves or steps around the enclosure 5 surrounded by the upper surfaces 21 to 23, and the fabric is not pinched, allowing smooth covering cutting. will be held.

Furthermore, even if scraps of the fabric adhere to the sliding surface 3 of the enclosure when cutting the fabric, the tangents 211, 221, and 231, which are the tangents of the concave sliding surface and the convex sliding surface, will come into sliding contact. 2
You can trace the surface of 1.22.23 and remove the residue, and the fabric will not stick when cutting the wrapping.

A conventional wrapping cutting device is shown in FIGS. 11 and 12. In this case, steps 50 are formed on both the upper and lower sides of the abutting portion of the sliding surface, so that folds in the shape of folds are created when cutting the fabric. Otherwise, the dough may become sticky.

Next, FIGS. 7 to 10 show the driving of the square piece 1 of this embodiment.
To explain based on the drawing, the housing 10 to which the assembly 4 is attached has an inner surface 101 when six square pieces L are used.
It has a hexagonal frame shape, and a drive ring 11 for sliding the square piece 1 is fitted to the bottom of this frame.

Drive pins 12 are attached to the drive ring 11 at predetermined intervals, and the pins 12 fit into elongated holes 25 of respective square pieces assembled into the housing 10.

A bar 15 protruding from a rod 14 is inserted into a pocket 13 attached to the lower part of the drive ring 11.

The rod 14 has one end pivoted to the arm 16, and the arm 1
The other end of 6 is pivotally fitted to the base 41.

Cam follower 18 attached to any position of arm 16
is fitted into a groove of a cam 19 rotating on the base.

Therefore, the rotation of the main shaft 40 causes the cam 19 to move to the cam follower 1.
8 is moved, the drive is transmitted to the drive ring 11 via the arm 16 and the rod 14, and as the square piece 1 moves, the inner surface 101 of the housing 10 and the outer surface 26 of each square piece l slide, and the enclosure 5 is moved. Open and close.

The base 41 moves up and down in synchronization with this opening and closing.

The base 41 is mounted on main shafts 40.40'' on both sides so as to be movable up and down.

A cam 42.42' is pivotally attached to the main shaft 40.40', and a cam follower 44 provided on a base arm 43 extending from a base 41 is fitted into a groove of this cam 42.42'.

When the cams 42 and 42' rotate, the base 41 moves up and down via the cam follower 44 regulated by the groove.

As described above, the opening and closing of the enclosure 5 formed by the square piece l is performed by the rotation of the drive ring 11, and in synchronization with this opening and closing,
The base 41 is moved up and down, and the enclosure 5 is closed when the base 41 is in the middle of its descent or reaches the lowest end, and then immediately opened and the base 41 is raised.

Another effect of the present invention is that the enclosure is closed in two stages: when the tangents 221 come together, and when the contacts 212 come together immediately thereafter, so when cutting a highly elastic fabric, the Even if the fabric cannot be completely cut only by cutting by the gathering, the fabric can be completely separated into upper and lower parts by cutting by the next contact point 212.

(Effects of the Invention) As described above, the present invention enables wrapping cutting to produce a smooth fabric surface without creating a rough pattern that occurs in wrapping cutting using conventional means, and also reduces fabric adhesion. Continuous operation is possible without generation, and high quality products can be provided.
