Description

The present invention relates to a food cutting technique (a food cutting method and a food cutting device) that uses relatively round vegetables and fruits such as cabbage, lettuce and pumpkin, and fruits such as watermelon as main cutting objects.

Conventionally, a cutting technique using vegetables as a cutting object is known (see Patent Document 1).
This conventional cutting technique is configured to cut a vegetable (mainly Chinese cabbage) being conveyed while providing a cutting cutter in the middle of the horizontal conveyance path and reciprocating the cutting cutter in the length direction.
In this case, the outer periphery of the object to be cut is held so as to be sandwiched between four horizontal conveyor belts, and while being held, the horizontal conveyor path is moved horizontally by the horizontal conveyor belt, and cut by a cutting cutter in the middle. It was supposed to go.

Japanese Patent Laid-Open No. 2001-269898

However, as in the conventional cutting technique, when the outer periphery of the object to be cut is sandwiched between four horizontal conveyor belts to move the horizontal conveyance path horizontally, the weight of the object to be cut is added in the vertical direction. Since the moving direction is the horizontal direction, the direction in which the weight is applied and the moving direction are perpendicular to each other, and the holding state during the movement is likely to be unstable.
For a cannonball shape with a length longer than the diameter, such as Chinese cabbage, even if it is a method of moving horizontally using a horizontal conveyor belt as in the past, a certain degree of stable holding state can be obtained Is possible.

However, in the case of a relatively round shape such as cabbage or lettuce, if it is moved in the horizontal direction with a conventional horizontal conveyor belt, the direction in which the weight is added becomes perpendicular to the moving direction. An unstable holding state occurs, and the object to be cut shifts due to resistance at the time of cutting by the cutting cutter.
As a result, there has been a problem that the original cutting function cannot be sufficiently performed, such as unevenness in the cutting location or disturbance in the cut surface.

According to the present invention, the moving direction and the holding direction are set in the vertical direction in accordance with the vertical direction to which the weight of the cutting object is applied, so that even a cutting object having a relatively round shape such as cabbage or lettuce is stable.

It is process drawing which shows the Example of the food cutting method which concerns on this invention. It is a schematic perspective view of the food cutting device used for this food cutting method. It is the whole food cutting device perspective view. It is the whole food cutting device top view. It is a perspective view which shows the receiving member and long blade of a food cutting device.

As shown in the figure, the food cutting apparatus used in the food cutting method of the present embodiment intersects with the receiving member 1 that moves up and down on the vertical line Z, the presser member 2 that moves up and down on the vertical line Z, and the vertical line Z. Thus, the lower long blade 3a and the upper long blade 3b extending in the horizontal direction are provided as main components.

The receiving member 1 is formed of a cylindrical body, and its axis line coincides with the vertical line Z so that a receiving raised position P1 (position in FIG. 1-A) and a receiving lowered position P2 (position in FIG. 1-E). Reciprocate vertically between them.
4 and 5, the upper surface of the receiving member 1 becomes a mounting surface 11, and the receiving plate 12 formed in a concave shape with the upper surface directed toward the center is integrally attached to the upper end of the receiving member 1. The cutting target K can be stably placed by the placement surface 11.
1, 2 and 3, the receiving plate 12 is not shown. In this case, the upper end surface of the peripheral wall of the cylindrical body is the mounting surface 11.

The presser member 2 is formed of a cylindrical body, and its axis is aligned with the vertical line Z so that the presser lift position Q1 (position in FIG. 1-A) and presser lower position Q2 (position in FIG. 1-E) Reciprocate vertically between them.
The lower surface of the pressing member 2 serves as a pressing surface 21 for the cutting object K. In the embodiment, the lower end surface of the peripheral wall of the cylindrical body is the pressing surface 21.

The lower long blade 3a extends in the horizontal direction with the cutting edge facing upward, and reciprocates in the longitudinal direction across the vertical line Z.
The upper long blade 3b extends in a horizontal direction so as to be perpendicular to the lower long blade 3a with a slight gap above the lower long blade 3a with the cutting edge facing upward, and the vertical Crosses line Z and reciprocates in the longitudinal direction.

Since the lower long blade 3a and the upper long blade 3b extend so as to intersect the vertical line Z as described above, when the receiving member 1 and the holding member 2 are moved up and down on the vertical line Z, The member 1 and the presser member 2 interfere with the lower long blade 3a and the upper long blade 3b.
Therefore, relief slits 10 and 10 are formed in the receiving member 1 downward from the mounting surface 11 at the upper end so as to straddle the long blades 3a and 3b from below.
Further, the holding member 2 is formed with relief slits 20 and 20 upward from the holding surface 21 at the lower end so as to straddle the long blades 3a and 3b from above.
Then, the lower long blade 3a and the upper long blade 3b are passed through the escape slits 10 and 20, and interference is caused by receiving the depth of the escape slits 10 and 20 and corresponding to the lifting strokes of the member 1 and the holding member 2. It is preventing.

Next, the support structure and drive structure of the receiving member 1, the holding member 2, the lower long blade 3a and the upper long blade 3b will be described.

In FIG. 3, reference numeral 9 denotes a pedestal, which is framed in a square shape in plan view, and the upper surface thereof is covered with a cover 91, and a circular work hole 92 is formed in the center of the cover 91. The center is set to the vertical line Z of the present invention.

A rail support post 81 is erected at the corner of the gantry 9 via fixing brackets 80, 80, and a vertical rail 83 is erected between the upper end and the lower end of the rail support post 81 via brackets 82, 82. The lower slider 8a and the upper slider 8b are slidably attached to the vertical rail 83, respectively.

The receiving member 1 is connected to the lower slider 8a via a lower connecting pipe 84, and the pressing member 2 is connected to the upper slider 8b via an upper connecting pipe 85.
The cover 91 of the gantry 9 is formed with a notch 93 for preventing interference with the lower connecting pipe 84 and the upper connecting pipe 85.

A pressing cylinder 70 is attached between the upper slider 8b and the lower slider 8a, and an elevating cylinder 71 is attached between the lower slider 8a and the rail receiving column 81.

A lower rail receiving member 60 is fixed to the gantry 9, and a lower linear rail 61 is supported by the lower rail receiving member 60 so as to be slidable in the horizontal direction, and is attached to both ends of the lower linear rail 61. Both ends of the lower long blade 3a are supported by the arms 62, 62.

An upper rail receiving member 50 is fixed to the gantry 9 above the lower rail receiving member 60 and at a right angle to the lower rail receiving member 60, and the upper linear rail 51 is attached to the upper rail receiving member 50. Both ends of the upper long blade 3b are supported by arms 52, 52 supported so as to be slidable in the horizontal direction and attached to both ends of the upper linear rail 51.
Since the upper long blade 3b is disposed near the work hole 92 of the cover 91, the blade is integrally attached to the receiving member 1 in consideration of safety as shown in FIGS. The cover 30 prevents the cutting edge from being exposed in a standby process and a mounting process described later.

Then, the L-shaped lever 4 is pivotally attached to the gantry 9 by the shaft 40, and the middle part of one arm 4a of the L-shaped lever 4 and the lower linear rail 61 are connected by the lower link 41, The tip of the other arm 4 b of the L-shaped lever 4 and the upper linear rail 51 are connected by an upper link 42, and the cutter cylinder 43 is provided between the tip of the one arm 4 a and the mount 9. Is mounted horizontally.

Next, the food cutting method of the present embodiment will be described in the order of steps with reference to FIG.
First, the standby process shown in FIG. 1-A is a stage before receiving the cutting object K, and the receiving member 1 is positioned at the raised position P1 and the holding member 2 is placed above the receiving member 1 to be cut. The presser is moved to the presser lift position Q1 through the K set space S.

Next, in the placing step shown in FIG. 1-B, the cutting object K is manually placed on the upper surface of the receiving member 1 from the set space S.
When the cutting object K has a core such as cabbage or lettuce, it is preferable to place the core so that the core faces upward on the vertical line Z as much as possible. However, it can be cut from the center of the core.
In addition, what is necessary is just to mount in the direction as needed, when it is not necessary to cut from the center of a core.

1C, the presser cylinder 70 is operated (reduced) to slide the upper slider 8b downward on the vertical rail 83, and the presser member 2 associated therewith is lowered from the presser lift position Q1. To hold the upper side of the cutting object K.
As a result, while holding the weight of the object to be cut K by the receiving member 1, the upper and lower sides of the object to be cut K are sandwiched from above and below by the pressing member 2 and the receiving member 1, and the holding state can be reliably stabilized. .

In the cutting step shown in FIG. 1-D, the lifting cylinder 71 is operated (extend) while the operation of the pressing cylinder 70 is fixed, and the upper slider 8b and the lower slider 8a are simultaneously slid downward on the vertical rail 83. Then, the cutting object K is lowered on the vertical line Z while being held by the receiving member 1 and the pressing member 2.
Thereby, the cutting object K can pass through and cut from the upper long blade 3b and the lower long blade 3a from the top to the bottom.

During the passage, the blade cylinder 43 is reciprocated (expanded), and the upper long blade 3b is connected via the L-shaped lever 4, the upper and lower links 42 and 41, and the upper and lower linear rails 51 and 61 in conjunction therewith. And the lower long blade 3a is reciprocated in the longitudinal direction.
For this reason, unlike a simple push cutting, a smooth cutting can be performed, and the cut end is clean and a hard object can be cut, so that the cutting can be reliably and safely performed.
In this cutting step, since the slits 10 and 20 are formed in the receiving member 1 and the holding member 2 as described above, interference with the lower long blade 3a and the upper long blade 3b can be prevented.

In this embodiment, since the two long blades of the lower long blade 3a and the upper long blade 3b are arranged at right angles, the cutting object K can be cut into four parts. What is necessary is just to make a long blade into one when cut in two.

In the collection step shown in FIG. 1-E, the cutting object K cut in the cutting step is dropped and collected.
In the cutting process, the receiving member 1 and the presser member 2 are lowered to the receiving lowering position P2 and the presser lowering position Q2 by the operation of the lifting cylinder 71.
From this point, the return operation of the lift cylinder 71 and the presser cylinder 70 causes the lift to the initial receiving lift position P1 and presser lift position Q1, but at this time the gap between the receiving member 1 and the presser member 2 is increased. Therefore, the holding state by the receiving member 1 and the pressing member 2 is released, and the cut object K that has been cut can be dropped from the periphery of the receiving member 1.
The falling cutting object K may be dropped directly into the storage bucket or the like and recovered, or dropped onto a conveyor or the like and taken out and recovered.

Then, the receiving member 1 and the presser member 2 are moved up to the receiving lift position P1 and the presser lift position Q1 to return to the initial standby process, whereby one cycle is completed, and thereafter the workpieces are sequentially cut while repeating the same operation. K is cut off.

The present invention is not limited to the above-described embodiments. In particular, the cutting device used in the cutting method of the present invention can adopt an appropriate structure depending on the object to be cut and other conditions. It is.
For example, as the raising / lowering driving means of the receiving member 1 and the holding member 2, and the reciprocating driving means of the lower long blade 3a and the upper long blade 3b, an air cylinder, a hydraulic cylinder, an electric motor or the like can be directly connected, a link mechanism, It is possible to adopt a structure as appropriate, such as connecting via a cam mechanism or the like.

Also, for the support structure of the receiving member 1 and the holding member 2, the lower long blade 3a and the upper long blade 3b, a linear way or the like in which a slider and a rail are slidably combined can be used appropriately, and the operation timing and operation For control of time and the like, a timer, a position sensor or the like can be used as appropriate.

In addition, the cutting object can be effectively used for vegetables having a relatively round shape (for example, cabbage, lettuce, pumpkin, etc.) and fruits (for example, watermelon, etc.). It can be applied as a method.
