Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention mainly relates to an aligning device for aligning thinly sliced pieces of ham, meat, etc.

[Conventional technology]

When ham or meat is sliced into thin slices (1 mm or less), the slices have no elasticity, so when they fall onto the conveyor belt, they may form wavy wrinkles or a large wavy protrusion in the center of the cut slices. It is hard to fold or fold in half and fall flat on the conveyor belt.

In order to avoid such troubles, conventionally the material to be cut is kept at a low temperature to make the cut pieces stiffer so that the above-mentioned bad conditions do not occur, and the cut pieces are arranged on a conveyor belt.

[Problem to be solved by the invention]

However, there are many problems with temperature control. For example, if roast ham or pressed ham that contains moisture is cooled to below 0°, the moisture will freeze, making it easier to slice, but the product will feel crumbly and lose its flavor. It will no longer be possible to sell it as such.

Furthermore, if the temperature of raw ham or the like is lowered too much, the cut pieces will curl and become cylindrical.

Also, the temperature of the cut object increases during slicing, resulting in stiff and stiff cut pieces.
The alignment becomes poor.

Furthermore, the optimum temperature for slicing an object has a narrow range, and each object has its own optimum temperature, and temperature control requires a great deal of skill.

Conventionally, even with such strict temperature control, slices can only be cut with a thickness of 0.7 mm to 0.8 mm, and thinner slices become weaker.
It was impossible to line up.

The purpose of the present invention is to enable the alignment of ultra-thin cut sections up to about 0.4 mm without requiring technically advanced temperature control as described above, and to allow the cut sections to be placed on a conveyor belt. An object of the present invention is to provide an apparatus for aligning thin slices of foods, etc., which can prevent wrinkles and bends.

[Means to solve the problem]

The apparatus for aligning thin slices of food or the like according to the present invention includes a holding table 3 that holds an object 4 such as food, and a holding table 3.
A blade that is disposed on one side of the lower end of the object to be cut 4 held by the object, and cuts the lower end of the object to be cut 4 to cut off a piece 15 by reciprocating in a direction intersecting the object to be cut 4. 1, and a cut piece 15 placed directly below the object 4 held on the holding table 3.
In an apparatus for aligning thin slices of foods, etc., which is equipped with a conveyor 5 that receives a sheet of food in the form of a flat plate, it is rotatably supported on a shaft and fixed to a drive shaft 7 that is interlocked with the conveyor 5 via a transmission means 14. a ratchet wheel 9, a lever 6 whose one end is rotatably supported on the drive shaft 7, and whose other end is rotated back and forth in conjunction with the slicing stroke and return stroke of the cutter 1 via a connecting means 12; It is rotatably supported by a lever 6, and its free end is engaged with the ratchet wheel 9 in only one direction of rotation. a feed lever 11 rotatably supported on the drive shaft 7; a feed lever 11 rotatably supported on the drive shaft 7; and the feed lever 11, and is interlocked with the return stroke movement of the cutter 1 and transmits only the adjustable rotation of the lever 6 to the drive shaft 7 to feed the conveyor 5. 10.

[Effect]

According to the investigation by the present inventor, the reason why the cut sections are wrinkled, folded, and bent on the conveyor belt is that the cut sections have no elasticity, so the cut sections hang down on the conveyor belt, creating wrinkles. It lies in falling (see Figure 1 B). In other words,
Since the cut sections come into contact with the conveyor belt in a slack state, this slack causes wrinkles and folds.

According to the above-described means, the slack of the cut pieces can be removed, the pieces can be dropped onto the conveyor belt without wrinkles or bends, and the pieces can be arranged in sequence (see FIG. 1A).

To slice an object such as ham, meat, cheese, etc., there is a slicing process in which the knife moves and cuts the object, and then, after cutting the object, the knife returns to place the object. There is a return stroke that sends out a fixed amount. These two steps are repeated alternately to perform slicing.

According to the above-mentioned means, in the slicing process, the cut piece hanging down and in contact with the conveyor belt in a slack state is pulled (on the knife side).
Since the conveyor belt is moved in this direction, the slack in the cut pieces is removed, and the generation of wrinkles and folds when the cut pieces fall onto the conveyor belt is prevented.

Further, when the slicing process is completed and the knife returns in the return process, the conveyor belt that has been moved to remove the slack in the cut pieces is returned to its original position, so that the next slicing process begins.

At this time, when the amount of movement of the conveyor belt to remove slack from the cut sections during the slicing process is equal to the amount of return when returning to the original position, the cut sections are piled up in a columnar shape.

Further, when the amount of return is greater than the amount of movement to remove slack, the cut pieces are lined up in a scale shape on the opposite side of the cutter.

On the other hand, when the amount of return is smaller than the amount of tension, the cut pieces line up in a scale-like manner toward the knife.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An apparatus for arranging thin slices of ham and meat, which is an embodiment of the present invention, will be described below with reference to the drawings.

In this embodiment, the apparatus for aligning thin slices of foods, etc. according to the present invention cuts a ham/meat (hereinafter sometimes referred to as an object to be sliced) 4 to cut off thin slices 15, and 15 groups on conveyor 5
It is configured to be arranged sequentially on a belt.

The ham/meat thinly sliced section alignment device according to the present embodiment includes a holding table 3 that holds an object 4 such as food, and a holding table 3 that is arranged on one side of the lower end of the object 4 held on the holding table 3. By reciprocating in the direction intersecting the workpiece 4, the lower end of the workpiece 4 is cut into pieces 1.
The conveyor 5 is provided with a cutter 1 for cutting off the cut pieces 15, and a conveyor 5 disposed directly below the cut piece 4 held on a holding table 3 to receive the cut pieces 15 on a belt in the form of a flat plate. On the opposite side of the cutter 1, a thickness regulating plate 2 is disposed slightly below the cutter 1, and is provided to slide in conjunction with the reciprocation of the cutter 1.

Further, this thin section alignment device includes a ratchet wheel 9 which is rotatably supported on a shaft and fixed to a drive shaft 7 which is linked to the conveyor 5 via a belt 14 as a transmission means, and a ratchet wheel 9 whose one end is fixed to the drive shaft 7. A lever 6 is rotatably supported by a lever 7 and whose other end is rotated back and forth in conjunction with the slicing stroke and return stroke of the cutter 1 via a connecting rod 12 serving as a connecting means. It is freely pivoted, and its free end is engaged with the ratchet wheel 9 in only one direction of rotation, and the ratchet wheel 9 is rotated by the rotation of the lever 6 that is linked to the slicing stroke movement of the cutter 1. A feed claw 8 that reversely feeds the conveyor 5 so as to take up slack on the conveyor 5 of the section 15, a feed lever 11 rotatably supported on the drive shaft 7, and the drive shaft 7 and the feed lever 11. and a one-way clutch 10 which is interposed between the two and transmits only the adjustable rotation of the lever 6 to the drive shaft 7 in conjunction with the return stroke movement of the cutter 1 to send the conveyor 5. There is.

Further, this thin section aligning device is equipped with a belt feeding roller, a feeding adjustment screw 17, and an engagement release cam 18, which are configured as described later. In addition,
In the figure, 19 is a rapid feed pulley, and 20 is a conveyor frame.

A conveyor drive lever 6 makes a pendulum movement in conjunction with the slicing stroke and return stroke of the cutter.
is loosely fitted on the conveyor drive shaft 7, and a ratchet feed pawl 8 attached to the conveyor drive lever 6 drives and rotates a ratchet wheel 9 fixed to the conveyor drive shaft 7, thereby moving the conveyor during the slicing process of the blade 1. The belt 5 is moved in the direction opposite to the advancing direction of the cutter 1 to remove slack in the cut piece 15 of the object 4. A belt feed lever 11 equipped with a one-way clutch 10 is attached to the conveyor drive shaft 7. During the return stroke of the cutter, the belt feed lever 11 is driven by the conveyor drive lever 6, and the belt feed lever 11 is driven by the one-way clutch 10. , the conveyor drive shaft 7 is rotated to return the conveyor belt 5 to the position at the start of slicing.

In other words, the belt of the conveyor 5 is reciprocated periodically. With this amount of movement, the cut pieces 15 do not line up in a scale-like manner, but are piled up in a column-like manner.

In other words, in order to arrange the pieces in a scale-like manner, the amount of movement of the belt of the conveyor 5, which was moved to remove the slack in the cut sections 15 during the slicing process, and the amount of movement of the belt back to the original position must be changed. .

Next, the operation of the apparatus for arranging thin slices of ham and meat in the case of arranging them in a scale-like manner will be explained with reference to the drawings.

As shown in FIG. 2, the conveyor drive lever 6 loosely fitted to the conveyor drive shaft 7 makes a pendulum movement by a connecting rod 12 that moves in conjunction with the slicing stroke and return stroke of the knife 1. At the end of the slicing stroke, that is, at the start of the return stroke of the cutter 1, the lever 6 is in the position A shown in FIG.
As the return stroke progresses, it moves to position B.

When the knife 1 returns to the right, the thickness regulating plate 2 also makes a similar movement, and when the knife 1 leaves the workpiece, the workpiece 4 falls onto the thickness regulating plate 2 and is cut. The thickness is regulated. In other words, the thickness of the cut section is regulated by the difference in level between the blade 1 and the thickness regulating plate 2.

When the knife 1 moves to the left while slicing, the movement of the connecting rod 12 that is linked to the movement of the knife 1 causes the conveyor drive lever 6 to make a pendulum movement to the left, gradually moving from position B to position A. do.
At this time, the ratchet feed pawl 8 attached to the conveyor drive lever 6 engages with the ratchet wheel 9 fixed to the conveyor drive shaft 7, causing the conveyor drive shaft 7 to rotate clockwise.

Since the conveyor drive shaft 7 and the feed roller 13 of the conveyor 5 are connected by the belt 14, the roller 13 of the conveyor 5 also rotates clockwise, and the belt of the conveyor 5 is gradually fed to the right. As the conveyor belt moves, the cut pieces 15 in contact with the belt are gradually pulled, so no slack occurs. Therefore, the slicing process ends,
When falling onto the conveyor belt, the sections 15 do not crease or bend, and the sections 15 fall flat on the conveyor belt.

When the slicing process ends and the cut piece 15 falls onto the belt of the conveyor 5, the blade 1 moves to the right, and in conjunction with this, the conveyor drive lever 6 also makes a pendulum movement to the right. At this time, as shown in FIG.
is attached to the conveyor drive shaft 7, and
Belt feed drive roller 1 to conveyor drive lever 6
6 is fixed in a protruding state, the belt feed lever 11 is pushed by the conveyor drive lever 6 via the rollers 16 and operates.

The one-way clutch 10 moves the belt of the conveyor 5 in the opposite direction of the cutting tool 1 when the ratchet feed pawl 8 shown in FIG. 2 acts to rotate the ratchet wheel 9 clockwise, that is, during the slicing process. It does not act when pulling the section 15, but acts during the return stroke of the cutter 1, and the conveyor drive shaft 7
and the belt feed lever 11 are configured to rotate together.

The conveyor drive shaft 7 is rotated clockwise by the ratchet feed pawl 8 and ratchet wheel 9 during the slicing stroke, and counterclockwise by the one-way clutch 10 during the return stroke. Further, the conveyor drive lever 6 includes a belt feed lever drive roller 1.
6 is equipped with a feed adjustment screw 17, and when the belt feed lever 11 is sandwiched and fixed by the belt feed lever driving roller 16 and the feed adjustment screw 17, the return stroke of the cutter 1 is adjusted. During the entire stroke, the one-way clutch 10 acts on the conveyor drive shaft 7, and the belt of the conveyor 5
It is sent in the opposite direction, that is, in the direction in which the cutter 1 moves.
Further, the feed adjustment screw 17 is loosened, and the distance between the belt feed lever drive roller 16 and the tip of the feed adjustment screw 17 is widened, and the belt feed lever 11 is set to play between them when the conveyor drive lever 6 swings. Then, the feed amount of the belt of the conveyor 5 decreases by the amount of play. In other words, the feed adjustment screw 17 can regulate the amount of belt feed in the direction opposite to the direction in which the cut piece 15 is pulled.

Next, the movement of the ratchet feed pawl 8 and the ratchet wheel 9, which operate to remove slack in the cutting section 15, will be explained.

During the slicing process, the ratchet feed pawl 8
engages the ratchet wheel 9 and rotates the conveyor drive shaft 7. However, at the midpoint of the return stroke, the outer periphery of the ratchet wheel 9 and the ratchet feed pawl 8 are separated by the disengagement cam 18. That is, the disengagement cam 18 is fixed close to the outer periphery of the ratchet wheel 9. The claw portion of the ratchet feed claw 8 is disposed on the outer periphery of the disengagement cam 18.
Therefore, the ratchet feed pawl 8 moves approximately half of the return stroke while remaining separated from the ratchet wheel 9.

During the first half of the slicing process, the ratchet feed pawl 8 moves while being separated from the ratchet wheel 9. Therefore, the ratchet wheel 9 does not rotate.

Next, the movements of the ratchet feed pawl 8 and the ratchet wheel 9, and the state of operation when the belt feed lever 11 equipped with the one-way clutch 10 is maximized will be explained step by step.

First, the blade 1 moves to the left toward the object 4 (see FIG. 2). At the same time, the conveyor drive lever 6 is moved by the connecting rod 12 from position B toward position A. The cutter 1 slices the workpiece 4, and at the midpoint of the slice, the ratchet feed pawl 8 engages the teeth on the outer periphery of the ratchet foil 9.

When slicing is continued, the ratchet feed pawl 8 rotates the ratchet wheel 9. at the same time,
The belt of the conveyor 5 pulls the cut sections 15.
The cut pieces 15 are sliced while being pulled by the belt of the conveyor 5.
falls on the belt.

When the slicing process is completed, the cutter 1 enters the return process. When the cutter 1 begins to return to the right, the connecting rod 12 also begins to return, so that the conveyor drive lever 6 begins to oscillate to the right.

When the one-way clutch 10 of the belt feed lever 11 installed on the back side of the ratchet feed claw 8 is fixed to the conveyor drive shaft 7, the conveyor drive shaft 7 rotates in the opposite direction to the direction in which the cut section 15 was pulled. The belt of conveyor 5 moves.

At the midpoint of the return stroke, the ratchet feed pawl 8 and the ratchet wheel 9 separate. Furthermore, the return stroke continues, and the cutter 1 leaves the workpiece 4. Item to be cut 4
falls on the thickness regulating plate 2, and the thickness of the cut section to be sliced is regulated.

In this case, the engagement between the ratchet feed pawl 8 and the ratchet wheel 9 is only effective for half of the slicing stroke. Also, the one-way clutch 10 of the belt feed lever 11 during the return stroke operates over the entire length of the return stroke. In other words, if the belt of the conveyor 5 is moved 10 mm in order to pull the cut section 15, it will move 20 mm in the opposite direction to the pulling direction during the return stroke.
I will have to move. In other words, the cut section is
They are lined up in scales at 10 mm intervals in the cutting direction of the knife (they are lined up sequentially to the left in Figure 2).

To make the bit less than 10mm, use the feed adjustment screw 1.
7 to increase the distance between the belt feed lever drive roller 16 and adjust the operating angle of the belt feed lever 11, the pitch at which the cut pieces 15 are lined up in a scale-like manner can be arbitrarily changed. can.

Further, when the function of the feed lever 11 is set to 0, the pieces 15 are arranged in a scale-like manner in the return direction of the cutter 1 at intervals of 10 mm.

〔Effect of the invention〕

As explained above, according to the present invention, cut sections can be neatly arranged in a columnar or scale shape without requiring technically advanced temperature control, regardless of the elasticity and stiffness of the cut sections. be able to. Furthermore, it is also possible to align thin slices of 0.3 to 0.4 mm, which was previously impossible.
