Description

TECHNICAL FIELD The present invention relates to a slicer that can be used for slicing processed or fresh fish meat or meat, vegetables, fruits, bread and the like.

(Prior Art) Conventionally, slicers that slice processed meat, fish meat, etc.
Various proposals have been made as exemplified in U.S. Pat. No. 4,308,778, in which a large number of blade-shaped blades are attached in parallel to opposing blade frames, and the blade frames are reciprocated in the opposite direction by actuation of a crank or the like. Along with the movement, the object to be cut 2 is pressed toward the blade surface 1 at a right angle as shown in FIG. 15 or with a slight inclination like for bread, and sliced to slice the product into blade rows. It was made to pass through.

Also, a slicer for obliquely slicing has been proposed as shown in JP-A-61-79597. In this diagonal cutting slicer, two blade frames are arranged so that the blades are inclined with respect to the product mounting table, and the blade frames are reciprocally moved in the length direction of the blades by using a crank mechanism. On the other hand, the object to be cut is pushed at a right angle with respect to the blade surface of the blade on the horizontal plane, but is sliced diagonally because it is pushed toward the diagonal blade frame.

(Problem to be Solved by the Invention) In the slicer shown in the above-mentioned conventional U.S. Pat. No. 5,771, the object to be cut 2 is pressed at a right angle to the blade surface 1 as shown in FIG. In addition, this conventional device requires a large-scale crank mechanism or the like to move the blade frame with the blade moved up and down, and since the blade reciprocates up and down, the height of the machine becomes high, so the device becomes complicated and the price is low. However, there is a problem that the cost cannot be used unless it is a factory for mass production.

Further, in the conventional diagonal cutting slicer, the blades are arranged obliquely, but the object to be cut 2 is pressed against the blade surface 1 of the blade at a right angle as shown in FIG. And also in this diagonal cutting conventional device to reciprocate the blade frame in which the blades are arranged,
It requires a large-scale crank mechanism and the like, and has a drawback of high cost.

The present invention is intended to solve the above-mentioned conventional problems, and an object thereof is to provide a slicer that can perform good slicing only by fixing a blade and pressing an object to be cut toward the blade surface.

(Means for Solving the Problem) Therefore, in the present invention, the object to be cut is pressed by the pusher toward the blade-shaped blades arranged in parallel, and the object to be cut is passed through the blade row. In the slicer for slicing diagonally, the blade is conveyed so that the rear end is located above the upper surface of the object to be cut and the front end is located below the conveying surface of the object to be cut. The blade is tilted with respect to a plane, and the blade side surface is not perpendicular to the plane constituted by the blade edges of the blades arranged in parallel, but is inclined obliquely to one side with respect to the vertical direction. The pusher is a plane formed by the blade tip on the transport surface,
The object to be cut placed on the conveying surface is guided so as to be pushed toward the blade row from a direction inclined at a predetermined angle, not a direction perpendicular to the line of intersection with the conveying surface. It is a means for solving the problem.

(Operation) Each sliced portion of the object to be cut is fed in parallel to the blade side face when passing through the blade row, and sliced with minimum resistance. Then, on the conveying surface in front of the pusher, the blade edge plane is installed at a predetermined angle with respect to the conveying surface, and each blade side surface is attached to the blade row that is inclined not at right angles to the blade edge plane, but with a blade edge plane. The object to be cut is placed along the front surface of the pusher arranged at a predetermined angle from the direction perpendicular to the intersecting plane of the conveying surface, and the pusher is moved to convey the object to be cut toward the blade, When pushed into the pointed plane and passed through the blade row, the object to be cut is extruded onto the table in front of the blade group as a product diagonally cut in two directions at equal intervals. The pusher then retracts and returns to its initial position, ready for the next step.

(Embodiment) The present invention will be described below with reference to embodiments of the drawings, and Figs. 1 to 8 show embodiments of the present invention.

Before explaining the structure of the embodiment of the present invention, the principle by which the slicer of the present invention can slice an object to be cut with good sharpness will be described with reference to FIGS. 10 (a) and 10 (b). The blade-shaped blades 3 for slicing the object to be cut 2 of the present invention are fixed in parallel at a predetermined interval without moving, and are inclined with respect to the transport surface 4 of the object to be cut 2. Is arranged. The inclination angle θ is preferably 5 ° to 45 °.

Now, as shown in FIG. 10 (a), the object to be cut 2 is pushed on the conveying surface 4 toward the apex plane 3a of the blade 3 as indicated by the arrow Z, and the apex surface 3a of the blade apex 3a is moved between a and c. Sliced while passing. Here, as in the conventional case of FIG. 15, at a right angle to the sharpened surface 3a of the blade b →
Let's think about the sharpness when it is pushed in like c.

When the XX section of FIG. 10 (a) is shown by the solid line in FIG. 10 (b), the section is shown by an isosceles triangle bcc ', and when the YY section is shown by a dotted line, the section is an isosceles side. It is indicated by the triangle acc '. In this case, if bc is h and ac is h _{1 in} Fig. 10 (a), h
Since it is clear that <h ₁ , the isosceles triangle bc
The apex angles β and β ′ of c ′ and acc ′ are β> β ′. In addition, the thickness of the blade 3 and the thickness of the blade polishing surface 3a in FIG. 10B are schematically shown thick for convenience of explanation.

Therefore, the working angle for pressing the object to be cut 2 against the sharpened surface 3a of the blade and slicing is such that the working angle β ′ when tilted so as to be pressed in the a → c direction is b → Since it is an acute angle than the operating angle β in the case of being pressed in the c direction, even if the pressing force of the object to be cut 2 from the arrow Z direction is smaller than the pressing force from the arrow W direction, it slices with good sharpness. It will be. Also, in a slicer with a moving blade, when the object to be cut is pressed in the W direction at right angles to the blade and the blade moves by ba in the direction of the arrow while passing bc, the blade edge angle is β '. Note that the smaller the inclination angle θ of the blade 3 is, the smaller the working angle β ′ is and the better the sharpness is.
If it is too small, the distance and time that the object to be cut 2 acts on the blade surface 3a becomes too long, so that the inclination angle θ is preferably about 5 ° to 45 °.

Next, the structure of the embodiment shown in FIGS. 1 to 8 will be described. The blade 3 has a blade tip 3 ′ that faces the conveying surface 4 as shown in FIG. 5, and the blade side surface is a plane formed by the blade tip. A lot of them in parallel with being tilted to one side from the vertical,
The rear end portion 3b is inserted into the slit groove 5a 'of the fixing member 5 fixed above the transport surface 4, and the front end portion 3c is positioned below the transport surface 4 so that the base 6 is slit. Groove 6
It is inserted in a '. 5a is a slit. The front side means the direction in which the cut object 2 is pushed out, and the rear side means the pushing direction. Also, at the rear end 3b, a pin 7 fixed so as to project slightly on both sides of the blade 3 is curved in an arc shape, and a spring 8 for sandwiching the rear end 3b of the blade 3 from both sides. The front part is hooked, and the protrusion 8a on the lower rear side of the spring 8
Is engaged with the concave portion 5b of the fixing member 5 while pulling a spring rearward, the blades 3 are fixed in the slit grooves 5a 'of the fixing member 5 while being stretched rearward. The fixing member 5 has bolts 9 on the base 6 on both sides.
It is fixed with a bolt 11 to the support member 10 attached by.
Reference numeral 12 is a cover fixed to the fixing member 5 by screws 13, and the blade 3 is prevented from coming off by the pressing portion 12a thereof.

On the other hand, a pin 14 is attached to the front end 3c of the blade 3 so as to slightly project to both sides as shown in FIG. 8, and the pin 14 is pulled to the end of the diagonal slit groove 6a 'of the base 6. Each blade 3 is fixed by hanging. Reference numeral 15 shown in FIG. 1 denotes a pusher having a groove 15a, which moves to the conveyance surface of the blade 3 at an angle of γ with respect to the parallel direction K of the projection line (equal to the direction perpendicular to the intersecting line between the blade plane and the conveyance surface). Thus, as shown by an arrow L, the object to be cut 2 on the conveying surface 4 is pushed in this direction toward the group of blades 3. Further, a rod 17 supported by a bearing 16 is extended rearward on the pusher 15, and a rack 18 provided on the lower surface of the rod 17 is meshed with a gear wheel 20 connected to a handle 19. When 19 is turned, rod 17 reciprocates back and forth via gear 20 and rack 18, and pusher 15
Is guided by guides 25, 25 provided on both sides of the blade 3, and the object to be cut 2 can be pushed toward the blade 3 group.

Next, the operation of the embodiment shown in FIGS. 1 to 8 will be described. With respect to the plane formed by the blade tip of the blade 3, the front side end portion is inclined with the blade side surface inclined to one side from the vertical direction. 3c is inserted in the slanted slit groove 6a ', and the pin 14 is hooked and fixed to the end portion of the slit groove 6a'. Next, the upper end 3b of the blade 3 is inserted into the slanted slit groove 5a 'of the fixing member 5, and the front part of the spring 8 is hooked on the pin 7 so that the protrusion 8a at the lower rear part of the spring 8 is first As shown in FIG. 5, by pulling and engaging the spring with the concave portion 5b of the fixing member 5, the blade 3 is in a tensioned state, and the slit grooves 5a ′, 6a ′ are inclined in the front-rear direction and in one side. Set accordingly. Next, by fixing the cover 12 to the fixing member 5 with the screw 13, the pressing portion 12a presses the rear upper surface of the blade 3 and the blade 3
Do not come off.

Next, the object to be cut 2 is placed on the front transport surface 4 of the pusher 15 as shown in FIGS. 1 and 2, and when the huddle 19 is rotated, the rack 18 and the rod 17 meshing with the gear 20 are inserted. The pusher 15 is guided by the guides 25, 25 to move forward, and pushes the object to be cut 2 toward the blade 3. The to-be-cut object 2 is an arrow L in FIG.
As shown in the figure, with respect to the line of intersection between the plane of the cutting edge and the conveying surface, it is pushed diagonally into the cutting edge surface at an angle of γ in the direction perpendicular to the conveying surface, so that it is pushed parallel to the blade side surface of each blade and slices diagonally After passing through the group of blades 3, the product 2 has a predetermined width and is diagonally cut in two directions as shown in FIG.
Then, it is extruded onto the front surface of the table 21. Then push the pusher 15 to the first position by turning the handle 19 in the opposite direction.
Return to the position shown in the figure and prepare for the next step. In addition, although the conveyance surface 4 in the above-described embodiments is fixed horizontally, the conveyance surface 4 is not limited to this.
The pusher may be powered.

Next, in the embodiment of FIG. 1 and FIG. 2, the sliced product is viewed diagonally from above as shown in FIG. The reason for slicing will be described with reference to FIGS. 11 to 14.

FIG. 11 is an enlarged view of the blade 3 seen from the direction of arrow M in FIG.
FIG. 12 is a plan view showing two blades 3. FIG. 13 is N of FIG.
-N sectional drawing, and FIG. 14 are the O arrow views of FIG. In addition,
The O direction is the same as the pusher traveling direction L in FIG. Now, in FIG. 11, the blade 3 is attached so that its cutting edge line 3'is at an angle .theta. With the conveying surface 4, and in FIG. 13, the blade 3 is a surface d to d'consisting of the cutting edges 3'of each blade. , And 90 ° -φ with respect to the plane perpendicular to the plane. Also, assuming that the width of the blade 3 is P, the width of the blade 3 seen from the side surface of FIG. 11 P ₁ = P × sin φ ...
And the width of the blade 3 seen from the plane of FIG. 12 P ₂ = P × cos
φ × cos θ ……

Further, in FIG. 11, the points where the horizontal plane of the height H ₁ of the transport surface 4 crosses the cutting edge and the trailing edge of the blade 3 are a ′ and b ′, respectively.
The points represented by a ₁ ′, b ′ and a ₂ ′, b ₂ ′ in FIG. 12 are points that cross the blade tip and the blade trailing edge of the horizontal plane of height H ₁ . Therefore, the cross section of the blade 3 cut across the horizontal plane of height H ₁
As shown in FIG. 3 ', the angle γ formed by the length direction a ₁ ′ -e of the blade 3 and the direction a ₁ ′ -f crossing the horizontal plane is the first
Unless the angle γ formed by the arrow L direction and the direction K in the drawing is the same, the object to be cut is not sliced along the side surface of the blade during slicing.

Here, in FIG. 12, when the lengths of (a ′ to b ′) in FIG. 11 are shown as (a ′ to b ′) E, (a ′ to b ′) E is in the height plane of H ₁ . a ′ ₁ −
Since b ′ ₁ is the length of the blade in the projection line direction with respect to the transport surface, γ = tan ⁻¹ {P ₂ / (a ′ to b ′) E} (a ′ to b ′) E = P ₁ / sinθ In FIG. 12, the line connecting the points a ₁ ′ and a ₂ ′ that intersects the cutting edges of the two blades 3 with the horizontal plane at the height H ₁ is perpendicular to the lengthwise direction of the blades 3, so that the pusher 15 By setting the front surface 26 parallel to the lines a ₁ ′ to a ₂ ′ and pushing the pusher 15 in the direction of the arrow O inclined by the angle of γ with respect to the direction of the blade 3, the object to be cut 2 is cut from the plane. It can be seen that it is sliced obliquely by the γ angle.

Further, in FIG. 11, the horizontal plane having a height H ₂ above the conveying surface 4 is the blade 3
Letting g and i be points intersecting the blade tip and the blade trailing edge, the line segments g to i in FIG. 12 are parallel to a ₁ ′ to b ′ ₁ and are slanted at an angle γ with the length direction of the blade 3. Has become. Further, in FIG. 12, a line m to q at which the blade 3 and the conveyance surface 4 intersect (slit groove 6
a ') is also the line G to I, a _1' a ~b _'1 parallel.

Next, in FIG. 11, assuming that the points intersecting the conveyance surface 4 of the perpendiculars from the points a ′ and g to the conveyance surface 4 are k and l, respectively, the length of k to l = {H ₁ −H ₂ ) / tan θ} ・ ・ ・ length of k to m = H ₁ / tan θ ...... Also in FIG. 12, the point a ′ ₁ point projected onto the transport surface is k.
And the point projected on the transport surface at point g is l. Let l ′ be the intersection of the perpendicular from the k point to the io line and io.
If the intersection of the perpendicular line to the mq line with the mq line is m ', kl' in FIG. 12 is kl 'in FIG.
The KM 'in FIG. 12 is the KM' in FIG.

k-l '= k-l * sin [gamma] km-' = km-sin [gamma].

Therefore, in the Figure 14 and more k-l a _{'= {(H 1 -H 2} ) / tanθ} × sinγ ...... than _{k-m' = (H 1} / tanθ) × sinγ ...... ∠km'a '1 δ is the angle between the sliced surface of the sliced product and the transport surface in the plane parallel to the front face of the pusher, and tanδ = (H ₁ −H ₂ ) / {(H ₁ −H ₂ ) / tan θ} × sin γ ＝ ta
nθ / sinγ …… From tanδ = H ₁ / (H ₁ / tanθ) × sinγ = tanθ / sinγ …… When the equation is analyzed here, φ is small when the angle θ is set to a predetermined angle ( The larger the inclination with respect to the vertical plane with respect to the cutting edge plane, the larger γ, that is, the angle sliced obliquely in the plane of the object to be cut, and δ, the angle obliquely sliced in the vertical plane of the object to be cut. Grows larger.

Next, referring to FIG. 14, the front surface parallel to the plane including the perpendiculars from the points a ₁ ′ and a ₂ ′ in FIG.
When slicing the object to be cut 2 by moving the pusher 15 having 26 in the direction of the arrow O in FIG. 12 (L direction in FIG. 1), assuming that the height of the object to be cut 2 is H _1. , Cut object 2
The upper surface of the blade hits the tip line of the blade 3 at points a ₁ ′ and a ₂ ′ and is sliced along a ₁ ′ → b ₁ ′, a ₂ ′ → b ₂ ′, but pushes the pusher 15 further. Then, the lower part of the object to be cut 2 sequentially hits the blade tip line along a ₁ ′ to g, a ₂ ′ to g ′, and a ₁ ′ to b ₁ ′, a ₂ ′ in FIG. in parallel with sliced ~b ₂ 'line. Also, the height of H ₂ starts to be sliced at g, g ′ points, and further lower positions are successively g ~ m, g '~ m'.
As it begins to be sliced along the blade tip line along the
As shown in Fig. 14, it is sliced obliquely at an angle of δ in the vertical plane.

Next, in Table 1, θ (blade inclination), φ (blade inclination), γ (angle of pusher pushing direction, tan ^-1 (sin θ / tan φ), δ
An example of calculation in the case of a relationship with (angle to be obliquely sliced on a vertical plane) is shown. The actual result is also approximately equal to this result.

(Effects of the Invention) As described in detail above, in the present invention, the blade is fixed in an inclined shape so as not to reciprocate, so that the blade surface of the blade to be cut that is pushed on the conveying surface toward the blade is The working angle is much sharper than the working angle when pressed in a right angle state. Therefore, the sharpness is improved by the amount of the sharp angle, and the object to be cut can be sliced easily and beautifully without pressing it with a large force.

Further, the present invention, the blade disposed inclined in the front-rear direction, the blade edge plane is further facing downward, and the blade side surface is inclined obliquely in one direction from a plane perpendicular to the plane,
The pusher pushes the object to be cut from a direction inclined at a predetermined angle so that the object to be cut is pushed parallel to the blade side surface in a plane parallel to the conveying surface with respect to the parallel direction of the blades. By simply pushing an object into the blade row, diagonal cutting inclined in two directions can be performed by one slicing operation.
