Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to an apparatus for applying relatively high viscosity fluid viscous substances such as butter and margarine to bread.

(Prior Art) Conventionally, applying butter or margarine to bread has relied exclusively on manual labor, and there has been no apparatus that can automatically apply the butter or margarine.

There are known devices for applying cream, which is a fluid viscous substance with a lower viscosity than butter or margarine, to the surface of a sponge cake (for example, Japanese Patent Application Laid-Open No. 1989-1999).
No. 57387, JP-A-54-107579, JP-A-54-
110379 etc.). In the case of these devices, the cream is extruded from a nozzle via a pump, and the extruded cream is smoothed onto the surface of the sponge cake using a leveling plate.

(Problems to be Solved by the Invention) Manual coating is not only inefficient, but also has the problem of making it difficult to equalize the amount of coating, making it impossible to avoid variations.

When applying the technique of smoothing cream with a leveling board to bread with butter, margarine, etc., butter and margarine have a higher viscosity than cream, so they have poor adhesion to bread, and the butter There was a problem in that some of the margarine and margarine remained on the leveling board side, making it difficult to apply it to the bread.
Furthermore, since the bread itself is soft, it tends to form dents, and even if it could be applied using a leveling board, a large amount of butter or margarine would be applied to the dented areas, making it impossible to expect an even application.

Incidentally, there is a method of melting butter or margarine and spraying it, but this method is not preferred because of the problem of deterioration of the quality of the applied product due to temperature rise.

(Means for solving the problem) The fluid viscous material coating device of this invention has extrusion nozzles installed oppositely above a conveyor for transporting the material to be coated, and can be operated in forward and reverse directions on the inlet side of the nozzles. A fluid viscous material pumping mechanism is provided in series, and the extrusion nozzle has a flat structure having a long side along the width direction of the object to be coated.

The extrusion nozzle is configured to have a width corresponding to the width to be applied, and when applying butter or margarine to the entire width of bread, it is opposed to the object across the entire width of the object.

The fluid viscous material pumping mechanism is only required to be able to pump the coating material to the nozzle side, and is composed of, for example, a gear pump, a cylinder pump, and a hopper.

That is, according to this invention, extrusion nozzles are installed opposite to each other above a conveyor for transporting the object to be coated,
A fluid viscous material pumping mechanism capable of forward and reverse operation is connected to the inlet side of the nozzle, and the extrusion nozzle has a flat structure having a long side along the width direction of the object to be coated. A fluid viscous material coating device is provided with a sensor for detecting the object to be treated, and the output of the sensor is connected to a motor circuit of the fluid viscous material pumping mechanism.

The extrusion nozzle is constructed of an end plate in which small holes are formed in a row at predetermined intervals on the exit side.

Further, the fluid viscous material pumping mechanism is composed of a gear pump or a cylinder pump and a hopper.

(Function) In the fluid viscous material application device of this invention, application is performed by placing the fluid viscous material, such as butter or margarine, extruded through a flat nozzle onto an object to be coated, such as bread. Therefore, a constant amount of fluid viscous material can be reliably applied regardless of the hardness or unevenness of the object to be coated. Further, the amount of application can be controlled by changing the speed at which the fluid viscous material is extruded from the nozzle (the amount of extrusion per unit time) and the speed of the conveyor.

Furthermore, the pressure inside the nozzle can be canceled by reversing the operating direction of the fluid viscous material pumping mechanism, so it is possible to improve so-called liquid drainage at the nozzle end. Therefore, it is possible to accurately apply the coating to the objects to be coated that are transported by the conveyor.

(Example) An example of this invention will be described below with reference to the drawings.

Extrusion nozzles 2 are installed opposite to each other above the middle part of a conveyor 1 laid horizontally. The extrusion nozzle 2 has an inlet side connected to a fluid viscous material pumping mechanism 5 consisting of a hopper 3 and a gear pump 4, while an outlet side has a width approximately equal to the width of the bread 6 transferred by the conveyor 1. As shown in Figure 4, the small holes 7,
7 are formed in a row at predetermined intervals (for example, 20 small holes of 1 mm diameter are formed at 5 mm intervals). The facing interval between the end plate 8 and the pan 6 is set to about 5 to 10 mm. A sensor 9 is installed below the extrusion nozzle 2 and outside the conveyor 1 to detect the bread 6 being transferred. In the figure, 10 is a drive motor for the gear pump 4, 11 is a box containing breads 6 to be coated, and 12 is a box for collecting the breads 6 after coating.

In the above device, when the conveyor 1 is driven in the direction of the arrow 13 and the breads 6 housed in the boxes 11 are sequentially placed on the conveyor 1, the breads 6 are placed in the boxes as shown in FIG. It is transferred to the 12th side. When the bread 6 passes below the extrusion nozzle 2, the sensor 9 detects this passage, and based on the detection signal,
When the drive motor 10 is driven to force the fluid viscous material such as butter or margarine in the hopper 3 to the extrusion nozzle 2 side via the gear pump 4, the fluid viscous material is extruded through the small holes 7 and into the pan 6. It is applied by placing it on the surface. Needless to say, the drive time, drive direction, and speed of the drive motor 10 of the gear pump 4 are set in consideration of the transfer speed of the conveyor 1, the size of the small holes 7, and the size of the pan 6.

When applying margarine with a temperature of 20 to 25℃,
When the rear end of the bread 6 passes below the extrusion nozzle 2, if the drive motor 10 is reversely rotated for about 0.2 seconds, the margarine extruded from the small hole 7 of the end plate 8 of the extrusion nozzle 2 can be cut. . When the drive motor 10 is rotated in the reverse direction, the margarine that has been pushed out to the small hole 7 is slightly sucked into the nozzle, so after cutting the margarine by rotating it in the reverse direction, the motor is rotated in the forward direction again (about 0.1 seconds). , it is desirable to prepare for the next application. The coated bread 6 is collected into a box 12 at the end of the conveyor 1. In this case, the two sheets may be collected as a set with their coated surfaces aligned.

In the above embodiment, the end plate 8 of the extrusion nozzle 2 is provided with a small hole 7, but it is also possible to form a slit-shaped extrusion gap. Furthermore, even if the gear pump 4 is a cylinder pump, it is possible to achieve the same extrusion action and perform the same application.

(Effect of the invention) As explained above, this invention has the effect of efficiently and uniformly applying a fluid viscous substance to a fixed amount. In addition, since the coating is applied through a nozzle that is spaced apart from the object to be coated, and there is no intervening contact member such as a leveling plate, the amount of coating can be made uniform without changing even if the object is uneven. Since there is no residual coating material on members such as leveling plates, it is hygienic.

Moreover, since the nozzle has a flat structure with long sides in the width direction of the object to be coated, even highly viscous margarine or the like can be reliably applied uniformly to the entire surface of the object to be coated.

In addition, the pumping mechanism is capable of forward and reverse operation, so
At the end of coating, the pressure feeding mechanism is operated in reverse to release the high pressure pressure in the nozzle part, which has the effect of improving liquid drainage.
