Abstract

PURPOSE:To provide the title system capable of preventing the products from flute formation, so designed that difference in level is eliminated and square- shaped blocks are made to slide, and even during enclosing process, an smooth surface is provided, thereby, when a packaging cover is to cut, the outer skin will not be picked up due to the above-mentioned difference in level. CONSTITUTION:A square-shaped block 1 has a recessed sliding surface 3 made up of upper surface 31, medium surface 32 and lower surface 33 and a projected sliding surface 2, and the former surface 3 is latched to the projected sliding surface 2' of the adjacent square-shaped block 1'. And, the latter surface 2 is latched to the recessed sliding surface 3'' of the oppositely adjacent square- shaped block 1''. The enclosure which is opened or closed by the sliding of the block 1 is closed by assembly of the tangential line 221 with the medium surfaces 32, 22 and also closed by the tangential lines 221 and 231 following above and below said tangential line 221, respectively; thus, when a packaging cover is to be cut, the outer skin will not be picked up due to the above- mentioned difference in level, therefore, flutes will not be formed on the products.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to the production of food products in which an inner packaging material is wrapped in an outer skin material such as a trowel or ohagi. Since it is possible to cut a continuous wrapped confectionery dough without exposing the center filling or creating folds on the surface, it can be used to produce various types of confectionery such as manju, and has great industrial effects. It is.

(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, there is a possibility that the surface of the dough may be Unevenness is formed, and if the surface of the outer skin is to be made flat and smooth, manual or other adjustments must be made, resulting in extra labor.

Another drawback is that during operation of these devices,
There was a problem in which the equipment caused burn-in due to heating, etc., which hindered continuous operation.

(Means for Solving the Problems) The present invention solves these drawbacks, and has a structure including a means for continuously supplying the rod-shaped wrapping material, and a means provided downstream of the rod-shaped wrapping material supplying means. An assembly consisting of a plurality of square pieces combined to form an opening at the center, said assembly comprising at least three or more square pieces each having at least two sliding surfaces, and an opening of said assembly In a device for wrapping and cutting a rod-shaped wrapping fabric, which includes means for opening and closing, the square piece 1 has an upper surface 31, a middle surface 32, and a lower surface 3.
3, and a convex sliding surface 2 consisting of an upper surface 21, a middle surface 22, and a lower surface 23, and the concave sliding surface 3 is a convex part of the adjacent square piece 1. The convex sliding surface 2 engages with a square piece 1'' adjacent to the opposite side.
, and the enclosure, which is opened and closed by the sliding movement of the rectangular piece, is closed at a set of tangent lines 221 with the middle surface 32.22, and the tangent lines 211. 2
31, the contact portion of the rectangular pieces of the surround formed by the structure of the present invention differs from the conventional shape in that there is no step and the rectangular pieces slide. Since it has a smooth surface even during the process of closing the envelope, the outer skin will not be pinched by the steps when cutting the envelope and the outer skin will not be picked up, so no folds will be formed in the product.

Also, the closing operation of the enclosure is changed from closing by tangent 221 to tangent 2
11, 231 and contact points 212, and a closure part that changes over time, it has become possible to cut easily sticky fabrics and highly elastic materials without any problems.

In the present invention, a solid lubricant is housed in the oil groove provided in the concave sliding surface to prevent seizure and enable continuous operation.

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

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.

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, and the convex sliding surface 2 of the negative square piece 1 and the concave sliding surface of the adjacent square piece 1" The moving surfaces engage.

As shown in FIG. 2, three or more rectangular pieces 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
12 to 12 pieces is appropriate.

The periphery of the enclosure 5 is constituted by a sliding surface 2, which is a surface that presses the rod-shaped fabric passing through the enclosure, and has a convex cross section in the axial direction of the rod-shaped fabric.

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.

Reference numeral 9 denotes an oil groove 9 provided in the concave sliding surface 3, which can accommodate a solid lubricant.

4 to 6 show the state in which the enclosure 5 is opened and closed by sliding the rectangular piece 1 in the direction of the arrow.

As the square piece 1 slides in the direction of the arrow, the box 5 becomes smaller, and eventually, as shown in FIG. Recesses 61 are formed at the top and bottom, but as the sliding progresses further, the recesses 61 disappear and the contacts 212 gather as shown in Figure 6.
There will only be a flat surface.

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.

The effect is as shown in Fig. 7, the thickness al of the generatrix contact surface of the sliding surface 22 remains unchanged a after contacting the fabric, and moves to the center of the enclosure 5, and the outer skin 6 is moved to the center. As it moves, the inner packaging material 7 flows in the direction of the 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.

Furthermore, since the concave sliding surface 3 engages with the convex sliding surface 2, the annular surface surrounded by the upper surfaces 21 and 23 around the enclosure 5 is
There are no grooves or steps, so the fabric is not pinched (smooth wrapping cutting is performed).

Further, even if scraps of the fabric adhere to the sliding surface 3 when cutting the fabric, the tangents 211, 221, and 231, which are the tangents of the concave sliding surface and the convex sliding surface, slide into 21. 2
2. Trace the surface of 23 and remove the residue, and the fabric will not stick when cutting the wrapper.

Further, the lubricating oil having the oil grooves 9 prevents seizure of the square piece during continuous operation, and at the same time suppresses adhesion as described above.

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. 9 and 10 show the driving of the square piece 1 of this embodiment.
To explain based on the drawings, the assembly 4 of the rectangular piece 1 is fitted into the housing 10.

A drive pin 11 is inserted into a hole provided in one square piece, and the other end is supported by a rod 12.

The rod 12 has one end pivoted to the arm 13, and the arm 1
The other end of 3 is pivotally fitted to the base 17.

Cam follower 14 attached to any position of arm 13
is fitted into the groove of the cam 15 rotating on the base.

Therefore, the rotation of the main shaft 16 causes the cam 15 to move toward the cam follower 1.
4 is moved, and the drive is transmitted to the drive bin 11 via the arm 13 and rod 12, and as the square pieces 1 move, each square piece 1 slides within the housing 10, and the enclosure 5
opens and closes.

The base 17 moves up and down in synchronization with this opening and closing.

The base 17 is mounted on main shafts 16.16'' on both sides so as to be movable up and down.

A cam 18.18'' is pivotally attached to the main shaft 16.16', and a cam follower 20 provided on a base arm 19 extending from the base 17 is fitted into a groove of this cam 18.18'.

When the cams 18, 18' rotate, the base 17 moves up and down via the cam follower 20 regulated by the groove.

In this way, the enclosure 5 formed by the square piece 1 is opened and closed by the cam 15.
The base 1 is rotated in synchronization with this opening and closing.
7 is moved up and down, but the box 5 closes when the base 17 is in the middle of its descent or when it reaches the lowest point.
is closed, and then immediately opened, and the base 17 rises.

Another advantage of the invention is that the closure of the box is tangent 22
Contact point 21 that occurs when 1 gathers and immediately after that
Since it is a two-step closure of the set of 2, even if the fabric cannot be completely cut by cutting only by the set of tangent lines 221 when cutting a highly elastic fabric, it can be completely cut by cutting by the next set of contacts 212. The dough can be separated into upper and lower parts.

As another example, the square piece shown in FIG. 3 has an arcuate sliding surface, and in this case as well, the same effect as described above was confirmed.

(Effects of the Invention) As described above, the present invention enables wrapping cutting to be performed with a smooth fabric surface without the folds that occur in wrapping cutting using conventional methods, and without causing burning. Continuous operation is now possible.
