Abstract

PURPOSE:To set the space between respective slicer blades to a prescribed space without depending on a travel guide by arranging the rotation axes of a pair of rotating drums not in parallel but in a crossing state. CONSTITUTION:Respective rotating drums 5, 6 are arranged in a separated, expanded and crossing state in such a manner that the axial directions of the one rotating drum 5 and the other rotating drum 6 form an angle having a central position in the axial direction of the respective rotating top drums 5, 6 as a top. Thus, each metal belt extending on the rotating drums 5, 6 are twisted between the pair of rotating drums 5, 6. Accordingly, a space between slicer blades 12c on the side edges of each metal belt 12 can be set to a prescribed space. Therefore, frictional resistance between the metal belt and a travel guide 15 is reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a slicer device for slicing foods and the like. More specifically, the present invention relates to a slicer device suitable for slicing root vegetables such as radish.

[Prior Art] FIG. 13 shows a schematic structure of a slicer device disclosed in Japanese Patent Application Laid-Open No. 2-131897.

In this device, a plurality of rows of endless metal belts 12 having slicing blades 12c on one side edge are used as cutters for slicing the material to be sliced. These metal belts 12 include an outgoing belt portion 12a of each metal belt 12.
It is suspended between a pair of rotating drums 5 and 6 so that the belt portion 12b and the return belt portion 12b intersect with each other. The pair of rotating drums 5 and 6, that is, the driving rotating drum 6 and the driven rotating drum 5 are arranged in parallel with their axes. In a region 18 where the outbound belt portion 12a and the return belt portion 12b intersect between these rotating drums 5.6, the side surfaces of the intersecting belt portions 12a and 12b may come into contact with each other and be worn out. Therefore, the interval between the belts, that is, each slicing blade 1
A travel guide 15 is provided to maintain the distance between the two parts 2c at a predetermined interval and to prevent the above-mentioned contact. This driving guide 1
5 form a pair sandwiching the intersection region 18 above and below, and
One pair is arranged for each of the outbound belt section 12a and the return belt section 12b. Each traveling guide 15 is formed with multiple rows of guide grooves (not shown) at equal intervals along the direction of the rotation axis of the rotating drums 5 and 6, and each of the guide grooves is provided with a plurality of rows of guide grooves (not shown) for each metal belt 12. is inserted.

As a result, each running metal belt 12 is forcibly bent as shown in the figure, and the slicing blade 12
c is guided so as to face the supply direction of the object to be sliced (the direction perpendicularly passing through FIG. 913 from the top of the page). Also,
Since the guide grooves are equally spaced, the interval G between adjacent slicing blades 12c in the intersection region 18 is maintained at an equal interval.

[Problems to be Solved by the Invention] However, as the operating time of the slicer device becomes longer, the guide groove of the traveling guide 15 becomes smaller than the metal belt 12.
It wears out due to friction. Along with this, the metal belt 12
It becomes increasingly difficult to keep the metal belt 12 at equal intervals, and the running vibration of the metal belt 12 increases. Furthermore, there is a problem in that the forced bending of the metal belt 12 increases in proportion to the interval between the slice widths, and the life of the metal belt 12 decreases.

The present invention has been made in view of the above problems, and its objectives are to reduce the wear of the running guide, suppress running vibration of the metal belt, and to reduce the running vibration of the metal belt regardless of the slice width. An object of the present invention is to provide a slicer device with reduced bending.

[Means for Achieving the Object] In order to achieve the above object, a slicer device according to the present invention is a device for slicing a supplied object to be sliced, and includes a pair of rotating drums arranged apart from each other. and,
Between these rotating drums, there are multiple rows of endless metal belts that are crossed at predetermined intervals in the axial direction of the rotating drums, and one side edge of which is formed as a slicing blade. In a slicer device that is equipped with a running guide that guides the running of each metal belt so that the direction of the slicing blades is opposite to the direction of the sliced object that is supplied to the crossed area in a cross-shaped area, one of the metal belts is The rotating drums are arranged in a crossed manner so that the rotating drums are spaced apart from each other so that the axial direction of the other rotating drum forms an angle with the apex at the center position of each rotating drum in the axial direction. It is characterized by:

[Operation] According to the arrangement of the pair of rotating drums in the slicer device as described above, each metal belt stretched between the rotating drums is twisted between the pair of rotating drums. Therefore, the interval between the slicing blades on the side edge of each metal belt can be set to a predetermined interval. Therefore, the frictional resistance between the metal belt and the running guide is reduced.

In addition, according to the above-mentioned effect, it is considered that a traveling guide is not necessary for maintaining the slicing blades at equal intervals.

However, the slicer device of the present invention includes a running guide to prevent the metal belt from meandering and to guide the direction of the slicing blade. Although some meandering occurs in the metal belt during operation, this meandering is prevented by sandwiching the metal belt between running guides. Furthermore, the holding of the metal belt by the running guide also serves to guide the direction of the slicing blade toward the object to be sliced.

[Example] FIG. 1 shows the main parts of the slicing device of the present invention.

In the figure, one side edge of a plurality of endless metal belts 12 is formed as a sharp slicing blade 12c.

Such a metal belt 12 is stretched between the driving rotary drum 6 and the driven rotary drum 5 so as to be aligned in the width direction. In this case, the intersection occurs in the rice region (intersection region) 18. Further, the metal belt 12 in the slicing area 18 is held by the running guide 15 so that each slicing blade 12c faces the insertion direction of the material to be sliced (the direction perpendicularly penetrating FIG. 1 from above). Ru. The details of this travel guide 15 will be described later.

As shown in FIG. 3, the driven rotating drum 5 and the driving rotating drum 6 have a rotating shaft (axis) 5a.

The drums 6a are mounted at an angle θ, that is, a diagonal angle θ, and are arranged in such a manner that they intersect on the axial center OI of both rotating drums 5 and 6. With this arrangement, the slicing blades 12c are arranged at equal intervals G along the extending direction of the rotating shafts 5a, 5a of the rotating drum 5.6. Depending on this distance G, the optimum angle θ for mounting is determined. This optimal angle is, as schematically shown in FIG. 4, relative to the insertion direction
This is the angle at which the belt surface 12e of the metal belt 12 is parallel. In addition, in Fig. 4, the white and black arrows are
Slice blade 1 for the outbound belt side and the return belt side, respectively
The direction of 2c is shown.

Table 1 shows an example of the optimum angle θ for attachment according to the interval G of the slicing blades 12c.

When the rotating drums 5 and 6 are installed at an angle θ as described above, the length of the metal belt 12 is determined from the center C of the width of the rotating drums 5 and 6, as shown in FIG. It gets longer as you get further away. However, as shown in Table 1, since the installation angle θ is relatively small, the difference in length L (j@ ) does not pose a practical problem, as shown in the rightmost column of Table 1. In addition, as a result of operating with the configuration shown in Table 1 using metal belts 12 of the same length, it was confirmed that the metal belt 12 did not slip even if the belt length difference was about 1.0 mm. This is because the surface of each rotating drum 5.6 is generally made of rubber. In addition, in the case of a combination in which the belt length difference is about 1.0 ms or more (D is 18 m5 or more), it is recommended to change the length of the metal belt depending on the position of the metal belt 12 stretched over the rotating drum 5.6. .

As an example of calculating the above theoretical displacement D (11111), ji
The case of the condition of Example 9 in Table 11 will be explained with reference to FIGS. 5 and 6. Here, the diameter of each rotary drum 6.6 is 300 cm, and the width of the metal belt 12 is 5 mm.

In this case, the distance be in FIG. 5 is bc=150·
tan (y/180・θ/2)−3,76(■l). As is clear from Fig. 6, the distance dividing the effective drum width into two equal parts is 32.5+gm, so the distance c
d is cd=32. 5-be -32,5-3,76 -28,74 (*polished). Therefore, the distance de, that is, the theoretical displacement, is de■D = cd number tan (π/180 ・θ/2)−28,
74・tan(π/180・θ/2)−1,44(s■
).

Further, an example of calculating the difference in length of the metal belt 12 is as follows. First, the theoretical length L0 of the metal belt at the center position of the drum width is determined. As shown in FIGS. 7A to 7D, the distance J0 between the drum axes is 1370 mm, and the theoretical length L0 of the metal belt is divided into three parts: xol ko +10. Here, xo is the intersection point 02 of the metal belt 12

Since the rotating drum radius r is 150 s+g and J o /2 is 885 m5, Xo "" 6852 1502 -668.375 (+++m). This distance X. and distance J in Figure 7B. /2

Next, an example of calculating the theoretical length of the metal belt (■l) at a non-center position of the drum width (32.5 mm from the center) will be described with reference to FIGS. 8A to 8E. Here, the distance between the drum axes is assumed to be J + (am) (Fig. 8B). In addition, similarly to the above calculation example of the theoretical length L0 of the metal belt, the theoretical length of the metal belt is xl (Fig. 8C), and 1 (
It is divided into three parts: (Fig. 8D) and l+ (Fig. 8E). The distance between the drum axes J1 is J1 = Jo' + (2, D) 2

(am) As described above, since the difference in belt length is very small, no problem occurs as described above.

FIG. 9 shows the whole of a root vegetable slicer device in which the above-described slicer device is applied to slice root vegetables (for example, radish).

In the figure, a frame 2 is erected on a base 1.

A support frame 4 is attached to one side of the frame 2, which supports the frame 2 on the base 1 and serves as a feeding platform 3 for the radish.

On the other side of the frame 2, the rotating drums 5 and 6 are arranged spaced apart from each other so as to sandwich the feed table 3 therebetween. Each rotating drum 5.6 has a rotating shaft 5 attached to the bracket 7, respectively.
g and 6a are rotatably held and attached to the frame 2 via these brackets 7. Here, the rotation shafts 5a, 6a of the rotary drum 5.6 are attached in the same manner as described above with regard to the angle relationship. A V-pulley 8 is coaxially attached to the driving rotating drum 6 located on the lower side of the rotating drums 5 and 6. On the other hand, an electric motor 9 located within the support frame 4 is fixedly arranged on the base 1. The output shaft of this electric motor 9 has a V
A pulley 10 is attached.゛These V pulleys 8
．． A V-belt 11 is stretched over the belt 10. As a result, the rotational force of the electric motor 9 is transmitted to the rotating drum 6 via the V-pulleys 8.10 and the V-belt 11, and the rotating drum 6 is rotated clockwise as shown.

Support rod 1 extending along the row direction of metal belt 12
3 are arranged in pairs on the upper and lower sides of the feed base 3, and are fixed to the frame 2 via brackets 14.

A travel guide 15 is attached to each support rod 13 so as to be slidable along the -1 longitudinal direction thereof.

Each of the rod-shaped traveling guides 15 shown in FIG.
As shown in Figure 0, it has an insertion hole 15a into which the support rod 13 is slidably inserted. The running guide 15 includes a metal belt 12 to guide the running of the metal belt 12.
The same number of guide grooves 17 are formed along the support rod 13 at equal intervals. A back portion 12d of the metal belt 12, that is, a back portion 12d on which the slicing blade 12c is not formed, is inserted into each guide groove 17. The width of the guide groove 17 along the support rod 13 is slightly larger than the thickness of the metal belt 12. In addition, each metal belt 12 while running
The depth of the guide 117 is made smaller than the width dimension of the metal belt 12 so that the slicing blade 12c does not rub against the guide groove 17 when it passes through the guide groove 17.

Furthermore, it goes without saying that the bottom surface of this guide groove 17 is inclined in accordance with the inclination of the metal belt 12. According to such a traveling guide 15, when the metal belt 12 is inserted into the guide groove 17 and travels, the metal belt 12 is guided so that its slicing blades 12c face the direction in which the material to be sliced is inserted. . At the same time, the metal belt 12
meandering is prevented. In addition, the traveling guide 15 is
A pair of guide grooves 17 are arranged on the upper and lower sides of the guide groove 17.
are arranged at equal intervals, so the upper and lower traveling guides 15
In other words, each slice blade 12c in the slice area 18
form a straight line at equal intervals.

In the rod-shaped running guide 15 described above, the interval between each metal belt 12, that is, the interval between each guide groove 17 is constant. If it is desired that this interval can be variably adjusted, a rectangular traveling guide 15 as shown in FIG. 11 may be used instead of the rod-shaped traveling guide 15 described above. In addition, in FIG. 9, this rectangular traveling guide 15
It is shown. The same number of rectangular travel guides 15 as the number of metal belts 12 are slidably attached to each support rod 13. Each travel guide 15 is made of a metal block, and a notch 15b is formed in one end surface of the block to allow the block to slidably fit onto the support rod 13. Furthermore, one guide 17 is formed for each block at the other end of the block. These traveling guides 15 are fixed at predetermined sliding positions on the support rod 13 by locking screws 19 (shown only in FIG. 11). Thereby, the interval between the slicing blades 12c can be set arbitrarily. The guiding operation of the metal belt 12 by such a rectangular running guide 15 is similar to that of the rod-shaped running guide 15 described above.

Referring again to FIG. 9, a protection rod 20 for preventing the metal belt 12 from falling off from the running guide 15 is arranged on the frame side near the running guide 15. These protection rods 20 extend along the row of slicing blades 12c, and normally leave a predetermined gap from the row of slicing blades 12c so that they do not come into sliding contact with the slicing blades 12c. Furthermore, fountain vibrators 21 are arranged near the upper and lower travel guides 15, respectively. This fountain vibrator 21 is connected to a water supply source (not shown) via a water supply vibrator 22 in which an on-off valve 23 is inserted. Each fountain vibrator 21 extends along a row of metal belts 12 and
On the side facing 2, a plurality of water fountains (not shown) are formed at predetermined intervals along the longitudinal direction. Cooling water is sprayed from this water spout onto the running guide 15 and the metal belt 12.

A rail 26 is fixed to the feed table 3.

This rail 26 is located on the side of the feed guide 24 and extends along the feed guide 24. This rail 26
A slider 27 is slidably attached to the. A post 28 is erected on this slider 27, and the post 28
An arcuate feed arm 30 is rotatably attached to the tip of the feed arm 30 via a pin 29. The feed arm 30 rotates in a direction perpendicular to the direction in which the radish is fed by the feed guide 24, and has a plurality of insertion pins 31 attached to its tip that can be inserted into the radish.

On the opposite side of the feed guide 24 with the slice area 18 in between, there is a guide 33 coaxially with the feed guide 24.
is located. This receiver is the guide 33, the frame 2
It is attached to a support arm 34 protruding from the support arm 34 so as to be rotatable in the vertical direction. Further, this receiver is configured such that the guide 33 is inserted therein, and the inner guide portion thereof is movable forward and backward with respect to the slicing area 18.

Furthermore, a cover 35 is attached to the frame 2. This cover 35 covers the rotating drum 5.6 and the metal belt 12, except for the front and rear of the slicing area 18.

According to the root vegetable slicer device described above, the rotating drum 5.
6, the radish is placed on the feed guide 24 with the metal belt 12 running. At this time, the root part of the radish should face the slice area 18. After inserting the insertion pin 31 of the feed arm 30 into the root portion of the radish, the radish is sent together with the feed arm 30 toward the slicing area 18. When the radish sent out in this way tries to pass through the slicing area 18, it is hit by the slicing blade 12C.
sliced by The root portion of the sliced radish is held by the guide 33, thereby stably feeding the radish.

The feeding of the radish is stopped when the radish has been sliced to near the base, and the radish is then turned back to complete the slicing. The radish thus obtained is sliced leaving the root intact, as shown in FIG.

〔Effect of the invention〕

As explained above, according to the slicer device of the present invention, the rotational axes of the pair of rotating drums are arranged not parallel to each other but in an intersecting manner, so that the interval between each slicing blade can be maintained at a predetermined distance without depending on the traveling guide. Can be set at intervals. Therefore, the frictional resistance between the metal belt and the running guide is reduced, and the running vibration of the metal belt is eliminated even during long-time operation. Furthermore, since the metal belt is not forcibly bent by a running guide as in the conventional case, the service life of the metal belt is also extended.
