Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rounding machine used for rounding irregularly shaped dough balls divided in a baking and confectionery process.

[0002]

2. Description of the Related Art As is well known, in the baking and confectionery process, irregularly shaped dough balls divided into appropriate sizes by a dividing machine are rounded by a rounding machine and then the intermediate fermentation of the next step is performed. proceeding. For example, as shown in FIG. 7, a conventional rounding machine 1 has a substantially frustoconical umbrella type 3 which is rotated by a drive source in a base 2 and an upwardly downward direction on the umbrella surface of the umbrella type 3. It is provided with a rounded blade 4 which is installed by swirling in a spiral shape and guides the divided irregularly shaped dough balls in a state of being compressed and rotated.

More specifically, a spindle 6 having a disk portion 5 at an upper end portion which is connected to a driving source in the base 2 and rotates about an axis is connected to a rotation center portion of the umbrella-shaped body 3, and the disk portion is formed. A plurality of radially extending support arms 7 are provided on the back surface of the support 5, and a connecting arm 8 for supporting the rounded blade 4 is attached to the tip of the support arm 7. In addition, a fixed base 9 is attached to the back surface of the disk portion 5, and the powder having a role of preventing the dough balls from being adhered to each other and the dough ball to the unloading surface of the next step after being rounded on the fixed base 9. Sieving machine 10 and this powder sieving machine 1
A motor 11 that operates 0 is installed. Each of these devices is positioned above the umbrella surface located near the upper end of the rounded blade 4. A dough ball recovery chute 12 for discharging a spherical shaped high-quality dough ball onto a delivery conveyor (not shown) for delivering it to the intermediate fermentation process of the next step is provided below the fixed table 9. .

The use of the rounding machine 1 having the above-mentioned structure will be described. First, irregularly shaped dough balls divided by a dividing machine as a pre-process are continuously covered with a dough ball carry-in conveyor (not shown). Drop on top. This dropped dough ball is thrown in between the lower start end of the round blade 4 and the umbrella surface, and is rotated above the round blade 4 while being compressed and rotated between the round blade 4 and the umbrella surface by the rotation of the umbrella die 3. It is guided toward the terminal end and shaped into a sphere. Then, the dough balls fed from the upper end of the round blade 4 and released from compression are discharged onto the dough ball collecting chute 12 and guided to the next intermediate fermentation process.

[0005]

However, according to the above-mentioned prior art, since the rounded blade 4 is always fixed at a constant inclination angle with respect to the umbrella surface, the round blade 4 is inserted between the rounded blade 4 and the umbrella surface. The size of the dough balls to be formed is limited to a certain range, and as a result, when shaping irregularly shaped dough balls outside the certain range, rounded blades with different inclination angles and sizes are used. The inconvenience of having to use another rounding machine 1 equipped with 4 arises. This causes a problem that it is necessary to secure a wide installation space for the rounding machine 1 in the factory, and it is necessary to prepare several kinds of rounding machines 1 in order to increase the facility cost and the like economically. Problems will also arise.

Further, when one type of rounding machine 1 is used as it is, the rounding blades 4 having different inclination angles need to be reattached, resulting in the inconvenience that it takes a lot of work and the work efficiency is lowered. The problem arises.

In order to solve the above problems, the present invention eliminates the need to secure a large installation space in a factory, and eliminates the need for arranging several types of rounding machines to reduce equipment costs and the like. An object of the present invention is to provide a rounding machine capable of accommodating various sizes of divided irregularly shaped dough balls which can improve work efficiency without replacing the rounding blades of the rounding machine.

[0008]

In order to achieve the above object, the present invention comprises a rounding machine having the following features. That is, according to claim 1, in a round-shaped machine having a substantially frusto-conical umbrella type which is rotated by a drive source and a round-shaped blade having a curved cross-sectional shape for guiding while rolling a dough ball between the umbrella-shaped umbrella surface. The round blade is elastically deformable by the pressing means.

In the second aspect, the pressurizing means is
It is composed of a pressurizing device for sending out a fluid, and a pressurizing tool for elastically deforming the rounded blades in which the fluid sent out from the pressurizing device flows in and out to expand or contract.

Further, according to a third aspect of the present invention, there is provided a substantially frusto-conical umbrella type which is rotated by a drive source, and rounded blades having a curved cross-sectional shape for guiding the dough balls while rolling between the umbrella type and the umbrella surface of the umbrella type. In the round eye machine, the round eye blades are held by opposed fixed blades, and a pressure receiving member is attached outside the guide surface of the round eye blades and interposed between the round eye blades and the fixed blades. A pressurizing tool that elastically deforms the rounded blades by accommodating a fluid sent from a pressurizing device, which is a pressurizing device, into and out of the member to expand or contract is included.

Further, according to a fourth aspect of the present invention, there is provided a substantially frusto-conical umbrella type which is rotated by a drive source, and rounded blades having a curved cross-sectional shape for guiding while rolling a dough ball between the umbrella type and the umbrella surface of the umbrella type. In the round eye machine, the round eye blades are held by opposing fixed blades and elastically deformable by a tension material.

[0012]

According to the above means, the rounded blade is easily elastically deformed by appropriately pressing in the predetermined direction by the pressing means. Specifically, when the pressure from the pressurizing means is not applied to the round blade, no change is seen in the tilt angle of the round blade with respect to the umbrella-shaped umbrella surface, and a large tilt angle is maintained, which is relatively high. Large irregular shaped balls can be shaped. On the contrary, when the rounding blade is pressed toward the umbrella-shaped side by the pressing means, the inclination angle is narrowed, and it becomes possible to shape a relatively small irregular ball.

In this way, one rounding machine efficiently shapes irregularly shaped dough balls of different sizes. However, shaping of irregularly shaped dough balls of many different sizes is performed by the dough ball. This is facilitated by appropriately finely adjusting the pressing force applied to the round-shaped blades in accordance with the size, and moving the round-shaped blades toward and away from the umbrella-shaped umbrella surface to change the inclination angle.

When the pressurizing means is composed of a pressurizing device and a pressurizing tool, the fluid sent from the pressurizing device may not flow into the pressurizing tool in advance. ,
Or, when the pressurizing tool is kept in a state where it does not expand, there is no change in the inclination angle of the rounded blade with respect to the umbrella-shaped umbrella surface, and a large inclination angle is maintained, resulting in division. Relatively large irregular shaped balls can be easily shaped. On the contrary, in the case where the fluid sent from the pressurizing device flows into the pressurizing tool in advance and the fluid is inflated as a whole, the expansion blade of the pressurizing element causes the rounded blades to move. By moving closer to the umbrella surface of the mold, the angle of inclination is narrowed, and it becomes possible to easily shape the divided relatively small irregularly shaped dough balls.

When the round blade is supported by the fixed blade and the pressure receiving member is attached to the outer side of the guide surface of the round blade as in claim 3, the expansion pressure of the pressurizer is mainly the pressure receiving member. Will act directly on. In particular,
When the fluid sent from the pressurizing device, which is the pressurizing means, flows into the pressurizing tool inside the pressure receiving member, it expands, and accordingly, the pressure receiving member is moved in a direction away from the expansion pressure of the pressurizing tool. Along with this movement, the rounded blade moves closer to the umbrella-shaped surface and the angle of inclination is narrowed, and it becomes possible to shape the relatively small irregularly shaped dough balls that are divided. If the pressure in the pressure tool is reduced in this state, the fixed blades will not receive the expansion pressure of the pressure tool, and the rounded blades will move away from the umbrella-shaped surface to widen the inclination angle and cause a large irregularity. It is possible to shape the dough ball.

Further, when elastically deforming the round blade with the tension member as in claim 4, when the tension member is pulled and tensioned, the inclination angle of the round blade with respect to the umbrella-shaped umbrella surface is narrowed and divided. In addition, relatively small irregular shaped balls can be easily shaped. On the contrary, if the tension of the tension material is weakened and loosened, the inclination angle of the rounded blade with respect to the umbrella surface of the umbrella type is widened and it is reasonably possible to shape a relatively large irregularly shaped dough ball. Become.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The rounding machine 1 according to the present invention is characterized in that the rounding blades 4 of the conventional rounding machine 1 are improved. The other components are basically the same as the above-mentioned conventional technique. Hereinafter, the description of the components at the same points will be simplified, and only the newly improved components will be specifically described. To

The rounding machine 1 according to the present invention is, for example, as shown in FIG.
As shown in FIG. 2, it is installed on the umbrella surface of the umbrella type 3 which is rotated by the drive source in the base 2 so as to swirl in a spiral shape from the lower side to the upper side, and the divided irregular shape. It has elastically deformable rounded blades 4 for guiding the dough balls A by compressing and rotating them and rolling them. In particular, it is suitable that the rounded blades 4 are held by the fixed blades 14 attached to the connecting arm 8 at the tip of the support arm 7 so as to be elastically deformable. Is not limited to the fixed blade 14. Specifically, as shown in FIGS. 3 to 4, the round blade 4 is made of an elastic material such as synthetic resin so that it can be elastically deformed. The guide surface 4a is formed so as to be curved so as to be recessed, and guides the dough ball A in a state of being compressed and rotated. The guide surface 4 of the round blade 4
The surface a may be subjected to a special surface treatment or the like to prevent the dough balls A from adhering.

The fixed blade 14 is provided on the side wall 14
It is a bent metal holding member having a and a pedestal 14b connected to one edge of the round blade 4. Side wall 14a
Is connected to a connecting arm 8 attached to the tip of the support arm 7, and the end edge of one pedestal 14b is connected and fixed to one end edge of the rounded blade 4 by a screw member 15 or the like.

A hard pressure-receiving member 16 having an outer wall 16a and a ceiling wall 16b and having a reverse L-shaped cross section is interposed between the rounded blade 4 and the fixed blade 14 which face each other. A bent connecting piece 16c is formed at an end edge of the ceiling wall 16b, and is fixed by a screw member 15 or the like at a position above the center outside the guide surface 4a of the round blade 4. At the outermost end of the pressure receiving member 16 located on the lower start end side of the rounded blade 4, the pressurizing tool 19 into which the fluid sent from the pressurizing device 18 constituting the pressurizing means 17, which will be described later, flows in and out does not hang down. In addition, in order to limit the expansion of the pressurizing tool 19 in the lengthwise direction as much as possible, it is preferable to provide an outer wall or the like to close it.

Further, in the pressure receiving member 16 described above, a stretchable tube made of a stretchable synthetic rubber or a plurality of stretchable synthetic rubbers or the like, which serves as a pressurizing tool 19 as the pressurizing means 17, is accommodated along the rounded blade 4. ing. The pressurizing tool 19 causes the fluid sent from the pressurizing device 18, which is a newly installed pressurizing means, to flow into and out of the fixed base 9 mounted on the back surface of the disk portion 5 of the main shaft 6. One end of the rounded blade 4 located on the lower start end side of the rounded blade 4 is closed so as not to leak, and the other end of the rounded blade 4 located on the upper end side of the rounded blade 4 is connected to the discharge port of the pressurizing device 18. Has been done. An air pump that generates compressed air is suitable for the pressurizing device 18, but the type of the pressurizing device 18 and the fluid are not limited, and the pressurizing device is a liquid such as water or oil. 18
May be used. Further, the installation place of the pressurizing device 18 is not limited to the fixed base 9 attached to the back surface of the disk portion 5 of the spindle 6, and the upper portion of the disk portion 5 of the spindle 6 and the rounding machine 1 can be used.
It may be placed independently on the floor surface in the factory.

The state of use of the rounding machine 1 of the present invention having the above structure will be described. For example, as shown in FIG. 3, when a relatively large irregularly shaped dough ball A is divided. Does not flow the fluid into the pressurizing tool 19 inside the pressure receiving member 16 interposed between the round blade 4 and the fixed blade 14 or weakens the pressurizing device 18 on the fixed base 9 in advance. The pressure tool 19 should be kept in a state of inflowing fluid so that the pressure tool 19 does not expand. Under this condition, the round blade 4
The other end edge of the non-connected side does not move closer to the umbrella surface of the umbrella type 3 and a large inclination angle is maintained, so that the relatively large irregular shaped dough ball A can be shaped. It will be possible without difficulty.

After the inclination angle or the curved surface of the rounded blade 4 is set large in this way, the relatively large irregularly shaped dough ball A is dropped on the umbrella surface of the umbrella mold 3. However, the dropped dough ball A is guided from the lower start end side of the rounded blade 4 toward the upper end side thereof, and in the process, the dough ball A is sandwiched between the rounded blade 4 and the umbrella surface and compressed. It is rolled while being rolled, and finally sent out from the upper end portion of the rounded blade 4 to be released from compression, and is collected on the dough ball collecting chute 12 mounted below the fixed base 9.

On the contrary, for example, as shown in FIG. 4, when shaping the divided relatively small irregularly shaped dough balls A, the pressing device 18 is operated strongly. ,
In advance, the fluid is made to flow into the pressurizing tool 19 inside the pressure receiving member 16,
The pressurizing tool 19 is allowed to expand as a whole. At this time, mainly, the expansion pressure of the pressurizing tool 19 is directly received by the pressure receiving member 16 attached to the outside of the guide surface 4a of the round blade 4, and the outside of the guide surface 4a of the round blade 4 and the pedestal 14b of the fixed blade 14 are also received. You will receive it together. As a result, the pressure receiving member 16 is entirely hard and the entire rounded blade 4 is elastic. Due to this pressure action, the pressing tool 19 moves the top wall 16b of the pressure receiving member 16 toward the pressing direction. The force acts to move the top wall 16b of the pressure receiving member 16 in a direction away from the expansion pressure of the pressure tool 19. Along with this movement, the round blade 4 attached so as to be elastically deformable has the connection point with the fixed blade 14 as a fulcrum, and the other end edge on the side not mainly connected with respect to the surface of the umbrella type 3. And the tilt angle is narrowed. After the inclination angle of the round blade 4 is set small in this way, in the same manner as described above, the relatively small irregularly shaped dough balls A are dropped onto the umbrella surface of the umbrella mold 3 to be shaped. To do so.

Further, when the inclination angle of the round blade 4 is changed and set from small to large, that is, because the divided relatively small irregularly shaped dough ball A is shaped, the pressing tool 1
In order to shape a relatively large irregularly shaped dough ball A from a state in which 9 has expanded in advance, the expanding fluid in the pressurizing tool 19 is provided at the discharge port of the pressurizing device 18. In addition, open the check valve, etc. so that it can flow out by a predetermined method. At this time, the top wall 16b of the pressure receiving member 16, which receives the expansion pressure, gradually returns to the original position as the expanding pressure tool 19 contracts. Along with this movement, the rounded blades 4 attached so as to be elastically deformable are similarly set with the connection point with the fixed blades 14 as a fulcrum, and the other end edge on the side not mainly connected is the umbrella type 3. The surface moves away from the surface, widening the entire inclination angle, and shaping becomes possible.

In this way, one rounding machine 1 efficiently shapes irregularly shaped dough balls A having different sizes. However, shaping of various types of irregularly shaped dough balls A having different sizes can be performed. While appropriately adjusting the flow rate of the fluid sent into the pressurizing tool 19 in accordance with the size of the dough ball A, the other end of the round blade 4 on the side not connected is mainly provided with an umbrella-shaped umbrella 3. This can be facilitated by moving the surface closer to and away from the surface to change the inclination angle.

The pressing tool 19 that pressurizes the round blade 4 to elastically deform it is not limited to a telescopic tube. For example, as shown in FIGS. 5 and 6, a tension member such as a wire may be used. The pressurizing tool 19 may be 18 as long as it can elastically deform the rounded blade 4. To describe one specific example of the configuration in this case, for example, as shown in FIG. 5, the support portion 4b for supporting the tension member 20 on the outer side of the guide surface 4a of the rounded blade 4 follows the spiral shape of the rounded blade 4. The tension member 20 is inserted into the support portion 4b. One end of this tension member 20 is, for example, a round blade 4 at the upper end portion.
Of the rounding blade 4 at the lower start end, and the other end is connected to a part of the rounding machine 1 such as the supporting arm 7 and the like.
It goes out and is connected to a pulling device (not shown).
In this case, when the tension member 20 is in a loosened state without being strained, the inclination angle of the rounded blade 4 with respect to the umbrella surface of the umbrella type 3 is maintained wide, and a large dough ball A can be shaped. Contrary to this, for example, as shown in FIG. 6, when the tension member 20 is pulled and tensioned by the tension device, the tension member 2
In 0, the distance from the umbrella surface of the umbrella type 3 is narrowed while the connection point with the support arm 7 and the like is used as a fulcrum, and the inclination angle of the rounded blade 4 with respect to the umbrella surface is also narrowed accordingly, which is small. The dough ball A can be shaped.

[0028]

In the rounding machine according to the first aspect of the present invention, it is not necessary to secure a wide installation space in the factory, and it is not necessary to prepare several kinds of rounding machines to reduce the equipment cost. Is possible. Further, since the shaping of irregularly shaped dough balls having different sizes can be handled by one rounding machine without replacing the rounding blades of the rounding machine, the work efficiency is improved.

The rounding machine according to the second aspect of the invention also has the same effects as the above, and since the pressurizing means is composed of the pressurizing device and the pressurizing tool, it does not require any trouble and is simple and easy. The round blade can be elastically deformed quickly, and the work efficiency is improved. And the certainty of dough ball shaping,
A rounding machine having good handling of the machine can be produced.

Also in the rounding machine according to the third aspect, the same effect as above can be obtained, and the inclination angle of the rounded blade with respect to the umbrella-shaped umbrella surface can be changed more easily and more reliably. Further, since the pressurizing tool is housed in the pressure receiving member, it is possible to use a pressurizing tool having a relatively small diameter, and it is possible to reduce the cost.

The rounded blade of the rounding machine according to the fourth aspect of the invention has the same effects as described above, and at the same time, the rounding machine can be manufactured at a low cost and with a simple structure, and the rounded blade is easily elastic. Deformation can be given.
