Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a device for mechanically dispensing cut food in a food cutting device, and in particular a device for mechanically dispensing cut food by rotating a rotary dispensing blade. It is something to put out.

[Conventional technology]

Conventional food cutting devices include, for example, a conveyor such as a belt conveyor that moves food, and a cutter blade installed facing the conveyance surface of the conveyor to cut the food while it is conveyed. The food is cut to the desired size using a cutter blade while the food is being transported.

However, in the case of such food cutting equipment,
Since the food is only transported in one direction to the end by the conveyor, it only passes through the cutter blade once. Therefore, in order to cut the food again for purposes such as cutting into small pieces, the food must be transported repeatedly, or Alternatively, it is necessary to prepare multiple cutter blades along the conveyance route and cut the food one after another, which takes time and effort if the food is repeatedly conveyed. The problem was that it was complicated and large.

Therefore, recently, a food cutting device has been provided which uses a rotary table as the food moving member to move the food endlessly and repeatedly cuts the food with a cutter blade, making the equipment simple and compact. There is. Therefore, in this type of cutting machine, if the cutting performance of the cutter blade and the type and amount of food are constant, the degree of food cutting is determined by the rotation speed or rotation time of the rotary table. Ru.

[The problem that the idea attempts to solve]

However, when a food conveyor such as the belt conveyor is used, the cut food falls or is scraped off at the tip of the conveyor, so it is relatively easy to take out the food. In a food cutting device using a rotary table, the rotary table moves the food endlessly, so the cut food remains on the rotary table.

Conventionally, this food removal was done manually, which not only led to poor work efficiency and accelerated deterioration depending on the type of food, but also was dangerous if the cutter blade was in operation. There are hygiene issues because people come into contact with the food.

In this way, a food cutting device that uses a rotary table to move food endlessly has the following features:
There was an unresolved issue that the removal of food after cutting was not automated.

[Means to solve the problem]

This device has a circular planar surface, the periphery and the center are high, and the planar annular portion between the two is recessed with an arcuate cross section, and this recessed portion forms the food loading section. In addition to being connected to each other, a cutter blade is mounted on a rotary table and moves through the rotation of the rotary table to cut the food.
In a food cutting device installed facing a food loading section of a rotary table, a rotary dispensing blade whose rotating tip has a locus along a cross-sectional arc of the food loading section is centered on the cross-sectional arc of the food loading section. Relating to a food dispensing device in a food cutting device, which is arranged with a rotating axis and a guide for guiding the food dispensed by the rotary dispensing blade to the outside on the outer side of the rotary dispensing vane at the periphery of the rotary table. .

It is preferable that the rotary dispensing blade is movable up and down, and is lowered only when dispensing the cut food.

[Effect]

The food is loaded on the food loading section and the cutter blade is operated while rotating the rotary table to cut the food. Since the food can be rotated endlessly by the rotary table, it can be repeatedly cut by the cutter blade if necessary. The food cut into the desired state reaches the position of the rotary delivery blade, and is delivered outward from the rotary table by its rotation. Since the trajectory of the tip of the rotary dispensing blade follows the cross-sectional arc of the food loading section of the rotary table, the cut food from the food loading section is forcibly discharged. Then, the dispensed food is guided by a guide from the periphery of the rotary table and moved to the outside.

Although not shown, the receiving member 4 or the rotating shaft 5 is supported by a thrust bearing relative to the machine frame 2. Furthermore, there is a pressing member 8 on the upper surface of the center 3b of the rotary table 3, which presses the rotary table 3 against the receiving member 4. However, if the rotating table 3 is securely supported by the receiving member 4, the pressing member 8 is necessary. do not have.

A cutter blade 9 is installed on the food loading section 3c of the rotary table 3. Katsuta blade 9 is 3
The cutter blades 9 are fixed at equal angles to the rotating shaft 10, and the locus of the tip of each cutter blade 9 is determined by the rotary table 3.
The rotation axis 10 is located along the arc that is the cross section of the food mounting portion 3c, and the rotation shaft 10 is located at the center of this arc.
The rotating shaft 10 extends to the rear side of the cutter blade 9 in FIG. 1, is supported by the rear part 2b of the machine frame 2, and has a rear end connected to a motor (not shown) serving as a rotational drive source. It is desirable that a plurality of types of cutter blades 9 be prepared depending on the type of food to be cut and the purpose of cutting, and that the selected cutter blade 9 be mounted on the rotating shaft 10.

A cutter blade 9 is mounted on the top surface of the rotary table 3.
A cover 11 is applied over the front and back. This cover 11 also has an arc shape having the same center as the food loading section 3c of the rotary table 3, and
b, so that no load is applied to the rotary table 3. The cover 11 can be opened and closed freely.

A rotary delivery blade 12 is further provided on the food loading portion 3c of the rotary table 3. Rotating delivery blade 1
2 has a rotating tip having a locus along the cross-sectional arc of the food mounting portion 3c, and is arranged with the rotating shaft 13 at the center of the cross-sectional arc of the food mounting portion 3c. This rotating shaft 13 has a fulcrum 14 at the rear part 2b of the machine frame 2, and is supported by a bracket 15a formed at the front end of an arm 15 that can pivot up and down. , a motor 16 serving as a rotational drive source is attached.

In this embodiment, the rotary dispensing blade 12 has a central portion curved in the direction of rotation, and has a shape that facilitates dispensing of the food. However, depending on the properties of the food, other shapes may be used. Of course, you can use anything. Further, it is desirable that the tip of the rotary dispensing blade 12 lightly slides into contact with the rotary table 3, but there may be some gap depending on the properties of the food.

A disk 17 that rotates integrally with the rotary dispensing blade 12 is fixed to the rotary shaft 13 on the rear surface of the rotary dispensing blade 12 . This disk 17 prevents the movement of the food moved by the rotary table 3, and
This is to increase the efficiency of payout by 2. Therefore, this disk 17 is not necessarily limited to rotating, but may be fixed to the bracket 15a. Whether this disk 17 is rotatable or fixed is determined as appropriate depending on conditions such as the properties of the food.

Furthermore, a cover 18 is supported on the bracket 15a. This cover 18 also has an arcuate shape having the same center as the food mounting portion 3c of the rotary table 3 at the position of the outer periphery of the rotary dispensing blade 12. Further, a guide 19 facing the peripheral edge of the rotary table 3 is supported by the bracket 15a via a cover 18.
The guide 19 guides the food dispensed by the rotation of the rotary dispensing blade 12 to the outside of the rotary table 3. In this embodiment, the guide 19 is
Although the guide 19 is supported by the bracket 15a via the bracket 8, the guide 19 may be supported by the machine frame 2 via another bracket or the like.

The rear end of the arm 15 is connected to an air cylinder 20, which is an elevating drive device, and is configured to pivot up and down about the fulcrum 14 by expanding and contracting the air cylinder 20. A compressor 21 is used as a source of air pressure to the air cylinder 20. Although not shown, the air cylinder 20 and compressor 21 are connected by a known pneumatic circuit. Note that other known drive sources and transmission mechanisms may be used as long as the device drives the arm 15 to rotate up and down.

A limit switch 22 is attached to the arm 15, and power is supplied to the motor 16 when the front part of the arm 15 is in contact with a contact piece 23 on the upper surface of the rear part 2b of the machine frame 2 by pivoting downward. There is. Reference numeral 24 shown in FIG. 2 indicates a control panel.

Then, with the air cylinder 20 retracted and the rotary dispensing blade 12 and cover 18 raised, food is put into the food loading section 3c of the rotary table 3, and the rotary table 3 is moved in the direction of the arrow in FIG. When the cutter blade 9 is rotated in the direction of the arrow in FIG. 1, the food is rotated by the rotation of the rotary table 3, and when it reaches the cutter blade 9 during the movement, it is cut. This is intermittent until the food reaches a predetermined size, and then the air cylinder 20 is extended and the arm 15 is rotated to lower the rotating delivery blade 12, cover 18, and guide 19, and the first and second The position is shown by the solid line in the figure. The timing of the extension of the air cylinder 20 is determined by the operation of a timer that is set based on conditions such as the purpose of cutting and the properties of the food when the rotary table 3 and the cutter blade 9 start rotating. However, the timing may be set by an operator while monitoring the cutting situation.

When the rotary delivery blade 12, cover 18, and guide 19 are lowered to the illustrated positions, the limit switch 22 is activated.
is turned on and rotates the rotary delivery blade 12 in the direction of the arrow in FIG. At this time, it is assumed that the rotary table 3 is continuing to rotate, and the cutter blade 9 may also be rotating, but may be stopped as long as it does not impede food movement.

By the rotation of the rotary dispensing blade 12, the cut food that reaches the rotary dispensing blade 12 is discharged by the rotation of the rotary table 3. At this time, since there is a disc 17 on the rear side of the rotary dispensing blade 12, the food is prevented from being rotated by the rotary table 3 regardless of whether the disc 17 rotates or not, and in this state, the rotary dispensing vane 1
2 forcibly discharged outward from the periphery of the rotary table 3. The paid out food is Guide 19
Since the food is guided in a predetermined direction by the container, the food is received in another container or the like and subjected to subsequent processing.

When this dispensing is completed, the air cylinder 20
is retracted, the rotary delivery blade 12, cover 18, and guide 19 are raised, and cutting is performed again. The operation of compressing the air cylinder 20 may be performed automatically as a time set by a timer elapses, or may be performed by an operator operating a switch. The limit switch 22 is turned off due to the rise of the rotary delivery blade 12, etc., and the motor 1 is turned off.
Stop 6.

Note that, in order to save labor, it is preferable that the operations of the rotary table 3, cutter blade 9, air cylinder 20, etc. be performed by sequence control. In addition, in the above embodiment, the rotary dispensing blade 12 etc. can be raised and lowered, but in the case of food whose predetermined cutting is completed by passing through the cutter blade 9 once, the rotary dispensing blade 12 etc. are not shown in the figure. Alternatively, if the machine is dedicated to such cutting, the structure may be such that it remains in the lowered state without having to raise and lower the rotary delivery blades 12 and the like.

Next, an experimental example using this embodiment device will be explained. As a food, 120 frozen at -20 to -30℃
An experiment was conducted in which frozen tuna weighing 1 kg was cut into pieces of 5 to 7 mm.
A comparison was made between a case in which manual dispensing was performed with the cover 18 and guide 19 raised and not in use, and a case in which automatic dispensing was performed using these. In both cases of manual dispensing and automatic dispensing, 120 kg of frozen tuna was divided into 20 kg, and this was successively loaded, cut, and discharged, and this process was repeated six times. As a result, it took a total of 180 minutes to chop and dispense 120 kg of frozen tuna manually, whereas it took 45 minutes to complete automatically. In the case of manual work, this is due to the longer cutting time due to the intermittent rotation of the cutter blade 9 during unloading to avoid danger, and the time required for manual work. In addition, in the case of automatic cutting, the cutting time is shortened because the cutter blade 9 can be continuously rotated even during dispensing, and it is recognized that the dispensing time by the rotating dispensing blade 12 is also shortened. Furthermore, it goes without saying that in the case of an automatic system, the only manual work required was to put in the food.

Then, when the cut frozen tuna was frozen again at -50°C and stored and thawed again, discoloration was observed in the manually processed tuna, indicating that oxidation had progressed. This can be understood to be due to the long time required in the manual process, which loosens the freeze and promotes oxidation before refreezing. On the other hand, the automatically dispensed tuna maintained its fresh red color and showed no deterioration in freshness.
This is because the cutting and dispensing were done within a short time.
It is recognized that the cause was that there was no opportunity for refreezing and oxidation before the freeze loosened.

In addition, the foods handled in this proposal include various foods such as preserved meat, fish, vegetables, and mixtures thereof.For example, it may be necessary to add each ingredient at once to produce the ingredients for gyoza. It is used for finely chopping and mixing.

[Effect of idea]

As explained above, according to this invention, even in a food cutting device that uses a rotary table to move food endlessly, the removal of food after cutting is automated, which shortens food processing time and allows manual handling. This has the effect of resolving work-related hazards and hygiene problems.
