Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is applicable to food materials that have no fluidity and always have an amorphous shape, such as vegetable salads and fruits. This device relates to a device that measures and extrudes vegetable fragments, fruits, meat pieces, etc. without applying excessive stirring or pressure, and fills them into bags or injects them into bread or croissants.

<Prior art and object of the present invention> As shown in FIG. 4, a conventional filling device consists of a cylinder 40 for measuring material, a piston 41, and an injection needle 42. The material to be filled with the cylinder can only be fluid, such as jam or cream, and the material is introduced into the cylinder by suction with a piston, whereas vegetables, fruits, etc. For non-flowable materials such as mixtures of
Material cannot be introduced into the cylinder using conventional suction means using a piston.

Therefore, in order to introduce these solid materials into the cylinder in the conventional apparatus, a pushing device is required directly at the inlet of the cylinder.

However, when the material pushed into the cylinder in this way is pushed out through the injection needle by the piston, if the inner diameter of the injection needle is significantly smaller than the inner diameter of the cylinder, the solid material will become plugged in the injection needle. Either the water does not leak out to the outside, or the shape of the material is destroyed due to intense pressure, and water is separated, making it impossible to perform the filling action that protects the characteristic qualities of the material, which is the object of the present invention. .

The present invention solves these problems and allows even soft fibrous structures such as strawberry or papaya pulp to be filled into other objects such as croissants rather than injection needles while preserving their almost intact state. It is an invention.

As for salads made by mixing the above-mentioned ingredients for the purpose of not destroying the fibrous tissue of the mixed ingredients vegetables and fruits or separating the liquid juice, there is a Japanese Patent Application Laid-Open No. There is a method disclosed in Japanese Patent No. 62-79765 that measures and extrudes a mixture of different materials.

The present invention is a new improvement added to the above-mentioned application, and it is possible to further improve the measuring function in addition to improving the quality.

<Means and effects for solving the problems> The present invention provides an agitator constituting a pusher plate that is removably housed in at least one slot provided in the direction of the generatrix of a rotating roller, on the hopper wall surface or on another slot. The agitator is placed facing the agitator at a constant interval, and the amount of action of this agitator can be varied.A groove with an approximately semicircular cross section is provided in the gap between the agitators, and a groove with approximately the same length as the agitator is provided in the gap between the agitators. A cylinder with a long opening on the side is fitted, a piston is fitted into the cylinder, the amount of rotation of the agitator is varied according to the characteristics of the material, and the cylinder is rotated so that the opening is half-open. When the circular groove is closed, the piston is moved forward and the material is pushed out through the injection needle provided at the discharging tip of the cylinder, and the material to be filled, such as croissant, is inserted into the injection needle. When the material is filled, the measured amount of material is filled into the object to be filled.

In order to weigh and extrude a mixture of solid materials such as vegetables and fruits, the present invention uses an agitator installed in the hopper to effectively push out the material through an elongated opening on the ventral side of the cylinder located below the hopper. It is pushed into the cylinder, then the cylinder is rotated, and the mass protruding from the ventral mouth is cut off to serve the purpose of metering. This reduces damage caused by friction and twisting stress.

The agitator used in the present invention has a structure having a pushing plate provided on the generatrix of the roller so as to be able to come in and out.

The feature of this is that the length of the roller can be increased without affecting other structures, so the pushing plate can also be lengthened, so the opening on the ventral side, which is the entrance of the material into the cylinder, can be made longer. I can do it. In other words, even if the inner diameter of the cylinder is reduced, the volume of the cylinder can be maintained at an ideal value by extending the length, so the inner diameter of the cylinder can be made as small as the injection needle.

That is, since the inner diameter of the cylinder and the inner diameter of the injection needle can be made almost the same, no vortex or plugging occurs during extrusion of the material. Therefore, even soft materials such as strawberries and papaya can be filled into bread, etc., without damaging the texture or shape.

<Example> An example of the present invention will be described below based on the accompanying drawings.

Reference numeral 1 denotes a hopper into which the material 20 is charged.

A pair of rollers 2 are installed at the bottom of the hopper 1 and serve as agitators that rotate facing each other.

The roller 2 is fitted onto the drive shaft 16, and a slot 36 is provided in the shaft 16 and the roller 2 in the generatrix direction, and the push plate 3 is provided in the slot 36 so as to pass through the slot 36 in the axial direction so as to be able to move in and out. be.

When the roller 2 rotates, the amount and timing of the pushing plate 3's protrusion from the outer peripheral surface of the roller 2 is controlled by a cam 4.

5 is a groove provided in the gap 6 where the roller 2 faces, and has a semicircular shape.

A cylinder 7 is fitted into this semicircular groove 5.

The portion of the pushing plate 3 that protrudes from the circumference serves to push the material 20 into the cylinder 7 at the position of the gap 6.

The cylinder 7 has an elongated opening 7' on its ventral side.
The distal end is connected to an injection needle 8, and the rear end has a gear 9.

The elongated opening 7' fits into the groove 5,
By being rotated by the gear 9, it opens in the direction of the hopper 1 and becomes an inlet for the material 20.

The material 20 in the cylinder 7 is pushed out from the tip of the injection needle 8 by a piston 12, which will be described later.

The gear 9 meshes with the gear 10, and since the motor 11 has the gear 10 fixed to its output shaft, the rotation of the motor 11 causes the outer periphery of the cylinder 7 to pass through the groove 5.
Rotate it while sliding it on the inner surface of the

12 is a piston that fits into the cylinder 7 and slides thereon.

The piston 12 is moved forward or backward by a threaded rod 14 which is rotated in forward and reverse directions by a motor 13.

The stop position of the piston 12 when moving forward or backward is determined by a proximity switch 21 attached close to the piston.
is determined by sensing a nearby object attached to the outer periphery of the piston 12 when the piston is moving, transmitting the signal to the control panel 15, and stopping the motor 13.

Therefore, by moving the position of the proximity switch 21 as necessary, the forward and backward stopping positions of the piston 12 can be changed.

This function will determine the amount of material 20 to be extruded.

The relationship between the operations of the piston 12 and the cylinder 7 is that when the cylinder 7 opens its side surface or attempts to open it, the piston 12 moves backward.

Further, when the cylinder 7 and the groove 5 form a closed cylinder, the piston 12 moves forward.

This control is motor 11 and motor 1
This is done by a program input to the operation control panel 15 of No. 3.

The control panel 15 is equipped with this external motor 1 as necessary.
A timer 22 that controls the amount of rotation of 7 is built in.

The motor 17 transmits an amount of rotation to the shaft 16 of the roller 2 through gears 18 and 19, which is predetermined by the timer 22.

Then, as the roller 2 rotates, the pushing plate 3 slides and rotates by a specified angle.

This pre-specified amount of rotation indicates the amount of rotation of the roller 2 that is synchronized with the operating cycle of the cylinder 7. It is possible to select angular rotation such as 1/4, 1/4, etc.

This selection allows you to select the amount of pushing that matches the characteristics of the material when using various materials.Experiments have shown that more pushing is required for salads than for fruits. is necessary.

The operating means may be one in which the rotation time and stop time of the roller 2 are freely selected by a timer 22, or one in which the roller 2 is divided equally on the side surface of the gear 19 so as to stop the roller 2 at a predetermined rotation angle. It is also possible to provide a proximity switch that senses the proximity object and its approach, and to stop the motor 17 in response to a signal from the proximity switch.

Further, as another means for controlling the amount of rotation of the roller 2, the drive motor 17 of the roller 2 is provided with a torque meter 35 for detecting the drive load. Then, as the roller 2 rotates, the increased internal pressure of the material filling the inside of the cylinder 7 is applied to the roller 2.
The torque meter 35 detects this,
When a certain torque is exhibited, the roller will automatically stop at that position.

This means detects the density of the material 20 filled inside the cylinder 7 to always obtain a constant degree of filling, and its purpose is to improve measurement accuracy.

Moreover, as a means for detecting the pressure inside the cylinder, in addition to a torque meter, the purpose can be achieved by providing a pressure sensor on the push plate 3 or the inner surface of the cylinder.

In addition to the above-mentioned embodiments, as shown in FIG. 3, a single roller may be used to push the material into a cylinder 7 provided below the gap between the hopper and the wall surface, which satisfies the purpose.

In addition, the configuration of the agitator in the embodiment of the present invention is explained as a roller consisting of a push-in plate that is housed in a slot provided in the generatrix direction of the rotating roller so that it can move in and out. However, when two rollers are placed facing each other, It is not necessary to use two identical rollers, and different types of rollers may be provided.

<Effects of the Invention> The effects of the present invention produced by the above-mentioned mechanism are as follows. A device consisting of a cylinder with an elongated material inlet, its rotary function and a piston mounted thereon, allows the extraction of juicy vegetables, fruits or meats protected by a delicate fibrous structure. It is possible to extrude a structure such as a boiled egg while repeatedly measuring a certain amount without excessive stirring or grinding, and fill it into other objects.
