However, bread dough or confectionery dough is viscoelastic, and melon bread biscuit dough is particularly sticky, making it difficult to form a clear mesh or streak pattern on the dough. After that, the mesh pattern or streak pattern may gradually become unclear, and it is necessary to deeply and firmly engrave the mesh pattern or streak pattern in the bread or confectionery dough at the molding stage.
Japanese Patent Application Laid-Open No. 2005-124510: “Food Molding Device” is a conveyor that conveys confectionery food, and is disposed so as to be transverse to the direction of movement of the conveyor, and the surface of the confectionery food can be rotated in a press-contact state. A blade for attaching a pattern to the surface of the confectionery food is formed on the surface of each of the two rollers, and the confectionery is produced by the rotation of the two rollers and the movement of the conveyor. A mesh pattern cut is formed on the surface of the food, but a dome shape like a melon bread can be engraved with a clear mesh pattern near the top, but the periphery has a mesh pattern. There is a problem that it is difficult to engrave clearly.

In addition, in the utility model 6-186016: “Biscuit float pattern forming device”, a biscuit stamping die in a die cut portion is pushed down by a linkage through a beam by means of a beam moving up and down by a rod and comes into contact with the biscuit fabric. When the pressure of the plate rises against the die, the die and the linkage rise, the push plate connected to the linkage rises, the ridge shrinks, and the abutment rod remains engaged with the leg frame This is a device that can push down the biscuit die strongly and press it firmly on the biscuit fabric through the linkage, and can form a clear floating pattern, but there is a problem that the biscuit fabric sticks to the mold .
Therefore, as a method to prevent the bread or confectionery dough from sticking to the blade or the mold, granulated sugar is attached to the surface of the biscuits dough of melon bread to suppress the adhesion of the dough, or the bite to the blade or the mold is shallow.

The linkage 5 is provided so as to face the side surface of the base of the restriction shaft 6 of the movement restriction part C on both sides, and is coupled to the restriction shaft 6. In addition, you may couple | bond the said linkage 5 with the following connection part 7 directly.
The presser 4 of the dough pressing part B is 60% to 90% of one space part of a diamond-shaped or other rectangular space part a formed by intersecting the plurality of vertical blades 2a and horizontal blades 2b. As long as the presser 4 can move up and down smoothly in the space, the area should be as large as possible. When the presser 4 has a larger area, The pattern f can be formed without damaging the dough because the amount of sinking on the surface is reduced.

The movement restricting portion C is connected to the fabric pressing portion B and regulates the downward movement distance of the fabric pressing portion B, and includes four restriction shafts 6 longer than the fabric pressing portion B, and When the lower end of the restriction shaft 6 contacts the bread dough placement surface F, the lower surface of the presser 4 of the dough pressing portion B is the surface of the melon bread dough E. The distance between the lower end of the restricting shaft 6 of the movement restricting portion C and the lower end of the presser 4 of the fabric pressing portion B is determined when the lower end of the restricting shaft 6 is grounded. The lower end of the presser 4 is a distance near the surface of the fabric.
The four restriction shafts 6 are provided so as to be positioned on the outer four sides of the stamp portion A, the upper part of the restriction shaft 6 is bent in an L shape, and two restriction shafts 6 on the left side and the right side are provided. Each is connected via a connecting portion 7.
The connecting portion 7 is connected to the restriction shaft C of the movement restricting portion or one of the linkages 5 of the fabric pressing portion B, and the connecting portion 7 is connected to the restricting shaft C of the movement restricting portion and the connecting shaft 7. It moves up and down integrally with the presser 4 of the fabric presser B.

In the thing provided with two or more connection parts 7, the penetration hole 8 can be provided in each, or the penetration hole 8 can also be provided in one side and the other.

The urging means D is supported by support rods 9 erected on both sides of a rectangular mounting plate 12 attached to the upper part of the stamp part A, and is connected to the stamp part A and the fabric pressing part B. The control part C is linked, and when the blade 2 enters the cloth by the lowering of the stamp part A after the control shaft 6 of the movement control part C is grounded, The upper part of the movement restricting part C and the upper part of the stamp part A are compressed apart from each other, and when the blade 2 is detached from the melon bread dough E, the dough holding part B is repelled by the compression. Is urged in a direction to hold down the surface of the melon bread dough E, and is used as a connecting portion 7 of the movement restricting portion C, the support rod 9, and a spring member arranged to enclose the support rod 9. Coil spring 10 , And a locking member 11 for locking the coil spring 10 fixed to the upper end of the bearing rod 9, and the bearing rods 9 erected at both ends of the mounting member 12 of the stamp portion A are arranged to the left and right of the movement restricting portion C. A coil spring 10 is fitted to each support rod 9 that passes through each insertion hole 8 of the connection portion 7 and protrudes on the left and right connection portions 7, and a locking member 11 is attached to the upper end portion of each support rod 9. It is. The urging means D is covered with a cylinder.
As a result, the urging means D and the connecting portion 7 are movable in the vertical direction along the support rod 9 that is vertically provided on the rectangular attachment member 12 provided on the upper portion of the stamp portion A. Yes.

  As the coil spring 10 of the urging means D, when the presser 4 of the dough holding part B comes into contact with the bread dough E, the spring coefficient is 0.5 to 1.0 N / mm so as not to bite into the dough surface. The compression coil spring is used.

Since the pattern forming apparatus for bread or confectionery dough in this embodiment has the above-described configuration, the connecting portion 7 between the stamp portion A and the movement restricting portion C before the operating rod 1 shown in FIG. When the operating rod 1 is in a contacted positional relationship and starts to move downward, the stamp portion A, the movement restricting portion C, and the fabric pressing portion B also start to descend in conjunction with this movement.
When the blade 2 of the stamp portion A hits the surface of the biscuit dough e of the melon bread dough E, the lower surface of the presser 4 is positioned slightly above the dough surface.

When the stamp part or the like is lowered further by the lowering operation of the working rod 1, the blade 2 starts to enter the biscuit dough e, and the dough is pressed down by a large number of blades 2 provided on the mesh made up of the vertical blades 2a and the horizontal blades 2b. As a result, the blade 2 starts to deform into a flat shape and the blade 2 also starts to enter the fabric. At this time, even if the lower surface of the presser 4 comes into contact with the fabric, the elastic force of the coil spring 10 can relieve the force at the time of contact with the fabric surface, so that the surface bites into the biscuit fabric e without hitting the fabric strongly. Will not hurt.
When the stamp part further descends, the lower end of the restriction shaft 6 of the movement restricting part C comes into contact with the placement surface F, the connecting part 7 of the movement restricting part C also stops at that position, and the cloth continuously provided to the movement restricting part. The lowering of the presser 4 of the presser part B is also stopped.
The stamp part A is further lowered to a predetermined position by the operating rod 1. As a result, the support rod 9 gradually descends in the insertion hole 8 of the connecting portion 7. Along with this, the stamp member A descends while the coil spring 10 is compressed by the coupling member 7 and the latching member 11 which are also stopped by the latching member 11 fixed to the upper end of the bearing rod 9. The lower limit of the lowering is that since the thickness of the biscuit dough e is usually about 5 mm, the width of the vertical movement of the working rod 1 is set so that the blade 2 is lowered by the thickness of the biscuit dough e. As shown in FIG. 3, the blade 2 cuts about 5 mm in thickness of the biscuit dough e to reach the bread dough under the biscuit dough e, so that a clear and mesh pattern f can be cut and formed in the dough. At this time, the lower surface of the presser 4 is in contact with the fabric surface or slightly above the fabric surface.

When the stamp part A stops descending at the above position, it immediately reverses and the operating rod 1 starts to rise, and the stamp part A also starts to rise, and the plurality of blades 2 that have invaded the biscuit dough e gradually become biscuit dough e. Begin to leave. Then, as shown in FIG. 4, the fabric pressing portion B is inserted into the insertion hole 8 of the connecting portion 7 where the stamp portion A starts to rise and the support rod 9 is stopped by the repulsive force of the compressed coil spring 10. The upper end locking member 11 is also raised. Therefore, the space between the connecting portion 7 and the locking member 11 spreads, but the repulsive force (restoring force) of the coil spring 10 causes the connecting portion 7 and the fabric pressing portion E to remain at the same position, that is, the movement restricting portion C. The regulation shaft 6 stays at the grounded position, and the blade 2 of the stamp portion A starts to be detached from the biscuits dough e of the melon bread dough E while the melon bread dough surface is pressed by the presser 4 of the dough holding portion B.
Eventually, as shown in FIG. 5, the blade 2 of the stamp part A is detached from the melon bread dough E in a state where the surface of the melon bread dough is pressed by the presser 4, and the stamp part A rises. 7 further opens (the distance between the upper side of the stamp part A and the upper side of the fabric pressing part B approaches), the repulsive force of the coil spring 10 becomes weaker, and the movement restricting part C together with the stamp part A And the regulation shaft 6, the fabric pressing part B and the pressing tool 4 also start to rise.

Thus, even if the stamp part A starts to rise after the blade 2 of the stamp part A has engraved the mesh pattern f into the fabric, the fabric pressing part B and its pressing tool 4 remain in the same position, and the stamp part A Since the blade 2 is raised, the melon bread dough E is gradually released from the state of being pressed flat by the elasticity of the blade 2 and restored to the original dome shape. The surface of the biscuit dough e hits the lower surface of the presser 4, and the blade 2 is raised while the surface of the biscuit dough e is pressed by the lower surface of the presser 4, so that the biscuit dough e adheres to the blade 2. Is also separated, and the blade 2 can be reliably detached from the melon bread dough E.
In addition, since a spring coefficient of 0.5 to 1.0 N / mm is used to balance the force with which the lower surface of the presser 4 holds the dough by the action of the coil spring 10 and the elasticity of the dough, It is also possible to prevent the presser 4 from biting into the dough surface.
Therefore, even if the blade 2 penetrates deeply until the biscuit dough e is almost cut and the melon bread dough adheres to the blade 2, the blade can be detached from the dough without damaging the dough surface, and the deep cut is clear. A melon bread dough E in which the mesh pattern f is formed over almost the entire area is completed, and even after being baked through a proofer, a melon bread having a beautiful appearance in which the mesh pattern appears clearly can be produced.

  FIG. 7 to FIG. 9 show different embodiments. Instead of forming a rectangular mesh pattern simulating the melon mesh of the above embodiment, this embodiment is a radial streak simulating a pumpkin pattern. FIG. 7 is a longitudinal front view before the stamp part is lowered. FIG. 8 is a front view of the stamp part, the movement restricting part is grounded, the stamp part is further lowered, and the blade is fixed to the bread dough. FIG. 9 is a longitudinal front view showing a state in which the stamp portion starts to rise, the dough pressing portion presses the bread dough surface, and the pressing blade is detached from the bread dough.
