Description
FIELD OF THE INVENTION
[0001] The present invention relates to an apparatus for producing
a vinegared rice rolled in dried laver or other rolled up foodstuff
or food product, and particularly to the apparatus which provides
products with steadily roll, and improvement for easy removal of
parts to be cleaned therefrom.
BACKGROUND OF THE INVENTION
[0002] Generally, the vinegared rice rolled in dried later is sold
in supermarkets or chain stores. The production of the vinegared
rice rolled in dried laver, insufficient handmade was carried out
by process in which a bamboo mat, dried laver put on the mat,
vinegared rice spread over the dried laver, and ingredients put on
the vinegared rice are rolled up with hands. Now, it is shifting to
the process in which the automatic apparatus with high effect
production are used.
[0003] As an example, Japanese Patent Publication 7-75512A
discloses such the automatic apparatus. The apparatus has a base
housing (not shown), a hopper 12 disposed above the base housing to
allow vinegared rice R to be contained therein and fed from its
lower opening, a roll maker 1 disposed below the hopper 12 for
producing a rolled up food product, and a feeder 13 disposed
between the hopper opening therebelow and the roll maker 1 so as to
feed the vingared rice R from the hopper 12 to the roll maker, as
shown in FIG. 1.
[0004] The hopper 12 stirs vinegared rice R with its stirrers 121
therein. The stirred vinegared rice enters into the feeder 13
through the hopper opening. The feeder 12 presses against and
spreads the fed, stirred vinegared rice R in a board shape with its
upper and lower rollers 132 and 133.
[0005] The roll maker 1 is assembled in the upper base housing at a
position below the outlet of the feeder 12, and comprises a base
board 2 having an opening at its predetermined position, and a
rolling plate 3 extending longitudinally of the apparatus and put
on the opening of the base board. The rolling plate comprises a
plurality of connective plates, preferably four serial plates, as
shown in FIG. 7.
[0006] The rolling plate 3 has a stationary plate 31 removably
fixed to or formed integral with the base board 2, first and second
rotating plates 32 and 33 rotatably connected to respective
trailing and leading portions of the stationary plate 31, and a
third rotating plate 34 connected to the leading portions (free
end) of the first rotating plate 32. The leading side surfaces of
the third rotating plate 34 have connections with link arms 35
which are connected to the predetermined portions of the base board
2 at positions midway between the leading and trailing portions of
the first rotating plate 32, respectively.
[0007] The roll maker 1 includes fan shaped flanges 321 and 331
mounted on one of side surfaces of respective first and second
rotating plates, a lift board 5 disposed below the base board 2 in
the lower base housing to move up and down by a drive such as motor
(not shown), and a pantographic lifting mechanism comprised of a
pair of lifter arms 4a and 4b connected between the fist and second
rotating plates, respectively, and lift plate 5.
[0008] The flanges 321 and 331 are downwardly arranged, protruding
from the reverse sides of the first and second rotating plates 32
and 33, respectively, such that one of respective radial edges with
respect to the arc is connected to each of first and second
rotating plates 32 and 33, while the respective other edges are
opposed to each other. At the lower radial edges of each flange 321
and 331, lifter arms 4a and 4b are pivotably mounted,
respectively.
[0009] The other ends of each lifter arms 4a and 4b are pivotably
mounted at the upper portions of an arm-mounting member removably
fixed in a recess at the upper portions of the lift board 5,
respectively. The fixation of the arm-mounting member in the recess
is a snap-on lock L.
[0010] When the lift board 5 begins to go up, the lifter arms 4a
and 4b operate to open sideward, each moving upward, as shown in
FIG. 8. The upward movement of the lifter arms 4a and 4b causes
upward rotation of both the first and second rotating plates 32 and
33 from their position at the base board 2, and the link arms 35
also upwardly rotate about the base board 2 so that the leading
portion (free end) of the third plate 34 comes up to the position
at the leading portion of the second rotating plate 33 with pull of
the link arms 35 connected thereto.
[0011] Turning to FIG. 7, when the rolling plate 3 extends between
the leading and trailing portions of the opening of the base plate
2, dried laver is placed on the first to third rotating plates deft
to right as shown in the figure). The vingared rice R in the hopper
12 passes through the feeder 13 to fall down into the dried laver
in the fixed plate 31, as shown in FIG. 1. When the board shaped
vinegared rice R falls down, it is cut in lengths by a cutter
device (not shown) in the feeder. Then, the required ingredients
are placed on the sheet shaped vinegared rice R.
[0012] Turning to FIG. 8, the first, second and third rotating
plates 32 to 34 are located to press against the side surfaces deft
and right surfaces) and top surface of the rolled up food product,
respectively. Thus, the vingared rice, the ingredients, and the
dried laver are rolled up by and formed into a stick shape in the
rolling plate 3.
[0013] Thereafter, when the lift board 5 begins to go down, the
lifter arms 4a and 4b operate to close to come back to the original
position. Thereby, the first to third rotating plates 32-34
downwardly rotate to come back to their original positions,
respectively so that the rolling plate 3 opens with extension of
the connective rotating plates. Thus, the vinegared rice rolled in
dried laver appears. As a result, the operator does only woks of
operating the apparatus, and putting the dried laver and
ingredients. It is obvious that the apparatus eliminates
requirement of the operator having sufficient skills, and allow the
operator to do easy preparation of the vinegaed rice rolled in the
laver.
[0014] The forgoing apparatus has a first problem of that the
transmitted push from the lift board 5 to the first and second
rotating plates 32 and 33 through the lift arms 4a and 4b forming
its pantograph-shape can not apply the sufficient force to press
against each of the rotating plates 32 to 34, depending on the
vinegared rice rolled in dried laver having its diameter that will
be larger. Since the food product has reaction with the pressure of
the rolling plate 3 when rolled up, the rolling plate 3 cannot
produce its sufficient action.
[0015] Therefore, although the apparatus serves sufficient function
as production of the vinegared rice rolled in dried laver that is
formed by a thin roll, it is not suitable for a thick roll
comprised of large amounts of vinegared rice and ingredients.
[0016] Furthermore, the apparatus has a second problem of having
difficulty in the cleaning works. Generally, parts of apparatuses
for producing rolled up food need cleaning after they end the
works. Turning to the cited roll maker, after removal of the base
board 2 from the base of the apparatus, its cleaning will be
carried out.
[0017] When the operator would like to clean the base board 2, he
has to open the snap-on lock L to separate the lifter arms 4a and
4b from the lift board 5. For opening of the snap-on lever, he is
required to put his hand Therefore, in the foregoing apparatus, the
cleaner has to do troublesome works for cleaning of the roll maker
1.
SUMMARY OF THE INVENTION
[0018] It is an object of the present invention to provide the
apparatus having a roll maker in which its rolling plate has
rotating plates with strong force applied to nori (a sheet of dried
laver or seaweed) or a other sheet-shaped food such as a omlette,
vinegared rice or other filler such as pilaf and minced meat, and
ingredients so as to produce strong thick or thin roll food
product.
[0019] It is another object of the present invention to provide an
apparatus for producing a rolled up food by a roll maker, which
eliminates connection of the lift board with the base board so as
to provide easy removal of the base board therefrom.
[0020] To accomplish the foregoing objects, the present invention
provides a roll maker which comprises a rolling plate, a base board
disposed thereunder, and a slid board disposed thereunder, having
improved relationship of movements of the rolling plate and the
lift board of the drive.
[0021] The improvement in the rolling plate is to provide cam
mechanisms symmetrically attached on respective first and second
back rotating plates. Each of the cam mechanisms is short in the
front height with respect to the back height so that the base is
curbed at the predetermined curvature, wherein respective front
faces are opposite to each other. The improvement in the drive is
to provide connecting relationship between the lift board thereof
and the cam mechanisms for changeover from the upward and downward
movement of the lift board to the rotation of the cam mechanisms
along the curved leading portions or bottom thereof. The rotating
cam mechanisms produce rotation of the first and second rotating
plates with its curved leading portions.
[0022] In this construction of the roll maker, direct push of the
lift board biases on the first and second rotating plates through
the cam mechanisms so that the rolled up food may be tightened with
much larger pressure. The cam members, which are attached on the
reverse first and second rotating plates, respectively, require
only their placement to a position where the lift board is brought
into contact therewith, and hence may be disposed independently of
the lift board. Therefore, the connecting relationship between the
lift board and the cam mechanisms, respectively, does not require
the snap-on lock that is applied to connection of the lift board
with the base board in the prior arts or foregoing apparatus. This
provides very easy removal and attachment of the base board from
and to the base.
[0023] In accordance with the preferred embodiment of the present
invention, each of the cam mechanisms has a plurality of rollers,
and each of curved portions of the cam members is a curvature with
approximate fitness for the arrangement of a plurality of rollers
along it. The arranged rollers act to provide decrease in
frictional resistance of the lift board against the cam
mechanisms.
[0024] In addition, each of the reverse first and second rotating
plates of the roll maker is provided with a lever for opening and
closure of the rolling plate. Each lever comprises an arm portion
and a hook of L shape extending from the leading portion thereof.
On the extended reverse rolling plate, the left, and right hooks
are inverted L with 90.degree. anticlockwise rotation by the right
angle, and L with 90.degree. clockwise rotation, respectively, and
their bases are opposed to each other approximately at the median
portion between the leading and trailing portions of the stationary
plate.
[0025] The slide board includes a base member, and a rolling plate
opening retention unit. The retention unit extends approximately
from the leading portion approximately to the trailing portion of
the base member, and has resilient forces against the leading
portions of respective hooks for opening of the rolling plate.
[0026] The forces of the retention unit comprises a pair of guide
shafts arranged in parallel to each other; a pair of right and left
slide blocks movably carried by the pair of guide shafts, and
having face to face contact with the leading portion of each of the
hooks; and springs having forces exerted in right and left pushes
on the trailing portion of respective slide blocks to cause the
hooks to move in the opening direction of the rolling plate under
the action of the push. Thus, the retention unit can retain opening
of the rolling plate.
[0027] In further addition, push of the closing rolling plate to
the rolled up food gains the force of the springs on the slider
blocks, since much reaction of the slider blocks against the
springs is produced by the upward movement and push of the lift
plate against the cam devices. The reacting force increases push of
the rotating plates to the rolled up food.
[0028] In accordance with the preferred embodiment of the present
invention, the slide blocks has each one push roller having
face-to-face contact with the leading portions of respective hooks
so as to decrease the frictional resistance of the hooks
thereto.

[0037] Description will now be made in further detail of the
composition of the present invention, referring with drawings.
Elements, which are same as or may be regarded same as that of the
foregoing prior art (FIGS. 7 and 8), are indicated by the same
numeral references.
[0038] Referring to FIG. 1, the reference numeral 1 shows a roll
maker according to the present invention, in combination with a
vinegared rice rolling mill 10. The vinegared rice rolling mill 10
is located at the top portion of the apparatus body, and comprises
a hopper 12 with an upper opening and an agitating element 121
therein, and a feeder 13 with upper and lower rollers 132, 133
arranged along the guide plate 131.
[0039] FIGS. 2 to 4 are top, left side and front perspective view
of showing a construction of the roll maker, respectively. The roll
maker 1 comprises a rolling plate 3, a base board 2 under the
rolling plate 3, and a slide board 8 under the base board 2. The
reverse side of the slide board 8 has a sliding engagement (not
shown) with a pinion gears 14 in its rack and pinion mechanism so
that the rolling plate is slidingly mounted on the apparatus body
11. The reverse side of the rolling plate 3 is provided with a pair
of cam devices 4 to bring the rolling plate into the folded shape;
and a pair of levers 5 which acts to open and close the rolling
plate.
[0040] Referring also to FIG. 5(a), the rolling plate 3 on the base
board 2 has a Aid stationary plate 31 fixed to the base board 2;
first and second rotating plates 32 and 33 rotatably mounted to the
trailing and leading portions deft and right as shown in figures)
of the stationary plate 31 through first and second pivots 311 and
312, respectively; and a third rotating plate 34 rotatably
connected with the leading portion of the first rotating plate 31
through and about a third pivot 321. The free leading portion of
the third rotating plate 31 connects with the base board 2 at the
predetermined position thereof through a link arm 35.
[0041] Each of the first to third reverse rotating plates 32 to 34
has right and left flanges, which are formed with holes at
respective leading and trailing portions, wherein the hole at the
leading portion of one rotating plate is connected with the hole at
the trailing portion of the other one by respective pivots 311,
312, and 321.
[0042] The cam mechanism 4 comprises fist and second cam devices 41
and 42 spaced apart from each other on same horizontal, the cam
devices downwardly protruding from, respectively, reverse first and
second rotating plates 32 and 33. The front faces of first and
second cam devices 41 and 42, respectively are symmetrically
opposite, and each vertical of the front faces is shorter than that
of the rear so that each bottom 43 has a curve at the predetermined
curvature, as shown in FIGS. 3 and 4.
[0043] Each of the base and slide boards 2 and 8 is formed having
openings or cutouts through which the cam devices 41 and 42 pass to
protrude beyond them. Each of first and second cam devices includes
a pair of parallel boards with respective curved bottoms, and a
plurality of rollers (three rollers) 44 arranged between the pair
of parallel boards along respective curved bottoms thereof and
pivotally mounted on respective shafts or pins. Each curvature of
the curved edges 43 fits in general with the arrangement of the
rollers. It is noted that the number and arrangement of the plural
rollers are not limited.
[0044] At the lower housing of the apparatus under the roll maker
1, there is provided with a drive mechanism 6, which comprises a
lift board 61 and a motor 65. The leading face 62 of the lift board
61 has a contacting relationship with bottoms of respectively, the
first and second cam devices 41 and 42, as shown in FIGS. 3 and 4.
The lift board 61 moves up and down with the driven motor 65, as
shown in FIGS. 5(a) to 5(c).
[0045] The motor 65 is provided with a disc-shaped motor arm 651 at
its eccentric position, the arm having a cam roller 64, as shown in
FIG. 4. The lift board 61 has a horizontally extending fit 63 in
which the cam roller 64 is fitted, as shown in FIG. 3. The fit has
a groove formed on its inner surface, and the raceway of the roller
64 is fitted in the groove. The engagement between the fit 63 and
the roller 64 transforms rotation of the motor 65 into the upward
and downward linear movement for transmission into the lift board
61, as shown in FIGS. 5(a) to 5(c).
[0046] Referring to FIGS. 3 and 6(a), the lever 5 for opening and
closure of the rolling plate comprises a first lever 51 on the
reverse first rotating plate 32, and a second lever 52 on the
reverse second rotating plate 33. On the reverses, the first and
second levers 51 and 52, respectively, are positioned on the
horizontal line spaced sideways from the cam member 4. Each of the
first and second levers 51 and 52 comprises an arm portion and a L
shaped hook 53. Their L shaped hooks 53 extend from the leading arm
portions which are at a point of the first and second rotating
plates from the medium to the trailing portion thereof,
respectively, as shown in FIG. 3. One of the L characters is
inverted, as shown in FIG. 6(a).
[0047] When the rolling plate 3 is mounted on the piled up base and
slide boards, the first and second levers can partially protrude
from the bottom of the slide board in the same manner as the
description of the cam devices. Each levers comprises a pair of
parallel boards which are disposed on the reverse rolling plate 3
that respective partial front (or bottom of the L character)
overlap at the intermediate portion of the stationary plate, as
shown in FIGS. 2 and 3.
[0048] On the reverse side of the base board 2, there is provided
with a rolling plate opening retention mechanism 7. The retention
mechanism 7 comprises a pair of guide shaft 71 positioned in
parallel arrangement on both sides of the lever 5 distant
therefrom, and a pair of right and left slider blocks 73 movably
carried by both the guide shafts, and springs 72, respectively,
fitted on the guide shafts at the left and right thereof so as to
push to the rears of respective slider blocks 73, as shown in FIGS.
2 to 4.
[0049] Each of the slide blocks 73 has a pair of parallel right and
left boards distally disposed on its approximate intermediate front
face, wherein the boards of respective pairs have a push roller 74
mounted therebetween through a shaft at respective intermediate
portions, and normally meet or contact each other at the distal end
of respective parallel boards under forces of the springs 72. The
hook 53 of each levers 51 and 52 protruding from the reverse base
board 2 is at the position spaced apart from the front peaks of
respective push rollers 74, at the time when the rolling plate 3
opens.
[0050] Description will now be directed to operation of the roll
maker 1. Operation of the cam mechanism 4 for producing a folding
up action of the rolling plate 3 is described with reference to
FIGS. 5(a) to 5(c), while operation of the lever for producing
opening and closing actions of the rolling plate 3 is described
with reference to FIGS. 6 (a) to 6 (c).
[0051] Referring to FIG. 5(a), the rolling plate 3 on standby is
shown, wherein the rotating plates 31 to 34 extend on the base
board 2 so that the rolling plate 3 is in the form of a flat sheet
shape. At the time, the opening and closing mechanism 5 is
positioned as shown in FIG. 6 (c).
[0052] On the rolling plate 3, dried laver(not shown) is placed,
before that the vinegared rice of a board shape is supplied and put
thereon from the vinegared rice rolling mill 10. Then, if required,
at least one of ingredients is placed on the board shaped rice.
[0053] Referring to FIG. 5 (b), the rolling plate 3 after an
operation switch (not shown) of the motor 65 being turning on is
shown, wherein the disk-shaped motor arm 651 is started in
clockwise rotation through the motor 65 to circle the cam roller 64
thereof clockwise and upward.
[0054] The circled cam roller 64, which is fit in the horizontal
fit 63 of the lift board 61, pushes the horizontal fit 63 up with
the torque to cause the lift board 61 to run up. The run lift board
61 produces the upward rotation of each first and second cam boards
41 and 42 with its force that push to their lower sides contacted
on its own leading portion, wherein the first and second cam
devices 41 and 42, respectively, have a rotation in opposed
directions to be in the form of an inverted v-shape so that the
first and second rotating plates 32 and 33 have a upward rotation
together, and the third rotating plate connected with the first
rotating plate also rotates upward or is pulled. At the time, the
lever unit 5 is positioned as shown in FIG. 6 (b).
[0055] Referring to FIG. 5 (c), the rolling plate 3 at the time
when the run lift plate is at the top position is shown. wherein
both the first and second cam devices 41 and 42 are located in a
substantially parallel relationship with the base board 2.
[0056] Both the first and second rotating plates 32 and 33 rise
perpendicularly, while the third rotating plate 34 is pulled from
the link arm 35, and thereby undergoes its rotation to come to a
position at the front of the second rotating plate 33.
[0057] Thus, the rolling plate 3 is folded to be in the form of a
substantially square in section so as to roll up the placed dried
laver, vinegared rice, and ingredients thereon, whereby the rolled
up food in the form of a quadratic prism appears. Producing the
vinegared rice rolled in dried laver, the lever device is a
condition as shown in FIG. 6 (a).
[0058] Thereafter, the rolling plate 3 is progressively opened by
the rolling plate opening retention unit as the lift board 61 is
started in downward movement with further rotation of the eccentric
cam roller 64 by the motor arm 651.
[0059] In this construction of the roll maker 1, the rolling plate
3 is directly subjected to the force exerted by the lift plate 61
being moved up, and hence produces great pushes of the first to
third rotating plates 32 to 34 as applied to the produced Norimaki
or rolled up foods.
[0060] Referring to FIG. 6 (a), when the rolling plate 3 has
complete rolling up of a sheet of dried laver, vinegared rice, and,
if required, ingredients, the levers 51 and 52 stand up straight
with respect to the base plate 2 so that each of the hooks 53
pushes to the roller 74 of the slide block 73, while the slide
blocks 73 push to respective springs 72 to come to the position
most distant from each other by pressing against the spring 72. In
order to push to the springs 72, each of side blocks 73 need
production of greater force than the force exerted on it by the
springs. The force produced by the slide blocks 73 causes increased
push of respective rotating plates to a roll appearing.
[0061] As stated above, the progressive downward movement of the
lift board causes rotation of the first and second cam devices
toward respective original positions.
[0062] Referring to FIG. 6 (b), when the progressive downward
movement of the lift board 5 decreases the push of slider blocks 73
to the spring 72 to cause increase in push of the slider blocks to
the hooks 51 and 52 such that the push rollers 74 may apply right
and left force to the hooks 53 of the levers 51 and 52 so as to
provide the opening of the rolling plate 3. Therefore, the levers
51 and 52 are progressively falling down toward the base board 2 to
allow for rotation of the rotating plates 32 to 34 in the direction
of opening thereof.
[0063] The application of the lateral force to the hooks 53 with
respect to the apparatus may be performed by slider blocks which
are of a hemispheric-shape at its distal end, in stead of the
pressing rollers 74.
[0064] Referring to FIG. 6 (c), when the lift board 61 reaches its
lowermost point, each of the levers 51 and 52 has a substantial
parallel relationship with respect to the base board 2 such that
the rolling plate 3 extends at the base plate 2. Thus, the return
of the rolling plate 3 to the standby state is made.
[0065] In this construction of the roll maker 1, the base board 2
has a complete separation from the lift board 61 so that the
operator may remove the base board 2 from the producing apparatus
without troublesome works of opening a snap-on lock that has
connection between the base board and the lift board.
[0066] It is noted that the present invention should not be limited
to the foregoing embodiments, the roll maker 1 may be used
independently of or separated form the rolling mill 10, the third
rotating plate 34 may be connected to the second rotating plate 33,
and the inventive concepts are susceptible of application to
modifications and equivalent techniques having same action or
effect as the foregoing elements.
[0067] Therefore, the foregoing roll maker may be applied to
production of rolled up foods except a vinegared rice rolled in
dried laver (Norimaki).
