DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for reversing and transporting fried material for smoothly inverting tofu as a raw material for frying and transporting the tofu to the next step.

[0002]

2. Description of the Related Art Oil fried food is fried tofu made of oil, and has a uniform network inside.
There is "Atsuage" where the inside remains tofu tissue.

[0003] In order to continuously produce a large amount of fried food, it is indispensable to put into a fryer the tofu cut into a predetermined size and conveyed by a conveyor. At this time, the tofu contains a large amount of water. Therefore, care must be taken when handling tofu because it is extremely easy to lose its shape. Therefore, conventionally, the process of taking out tofu from the conveyor and putting it into the fryer was usually performed exclusively by hand, but recently, for example, using a conveyor robot having a vacuum suction pad, A method of adsorbing tofu on an adsorption pad, transporting the tofu to a fryer, and throwing the tofu into a fryer has also been partially adopted.

[0004]

According to the prior art, the work by hand is inevitably the problem of securing labor and the problem of hygiene, and the work by robot is inevitable. However, there is also a problem that the work efficiency is not high, and that the mark of the adsorption pad is attached to the surface of the tofu, which may reduce the commercial value. Further, there is a problem that the operation reliability of the suction pad is not high, and the tofu often drops during transportation.

[0005] Since the tofu contains a large amount of water downward and a small amount of water upward on the conveyor, when the tofu is put into the fryer,
It is preferable to invert it up and down, but if such a reversing operation is performed by the transfer robot, the tofu is more likely to fall off the suction pad, the operation time becomes longer, and the transfer robot becomes complicated. Problems such as over-imposition occur.

Accordingly, an object of the present invention is to provide a rotating shaft that repeatedly rotates between a receiving position and a discharging position, and a receiving plate and a support plate that are attached to the rotating shaft, in view of the problems of the related art. This makes the overall structure extremely simple,
It is an object of the present invention to provide an apparatus for reversing and transporting fried material, which can efficiently invert the material from the conveyor and inject the material into the flyer.

[0007]

In order to achieve the above object, a construction of the present invention comprises, at the end of the conveyor, a rotating shaft disposed in the width direction of the conveyor, and a rotating shaft attached to the rotating shaft; A receiving plate for receiving a material that easily loses its shape due to containing water from the conveyor, and a slippery surface attached to the receiving plate at right angles to the rotation axis.
It consists of a support plate while creating the pivot shaft, the supporting plate and the receiving plate is lowered while the material immediately slid on the support plate from both obliquely upward posture and is not the conveyor with the receiving plate The gist of the present invention is to repeatedly rotate between a receiving position where the material is received once and a discharging position where the material on the receiving plate is inverted and discharged.

[0008] The front side of the support plate may be formed to have a cross-sectional waveform along the material receiving direction.

[0009]

According to the structure of the present invention, the rotating shaft repeatedly rotates between the receiving position and the discharging position, and in the former, receives the material from the transport conveyor on the receiving plate via the support plate. In the latter case, the material on the receiving plate can be inverted and discharged. In other words, the receiving plate and the supporting plate can receive the material on the conveyor once on the receiving plate and then invert and discharge the material once the rotating shaft rotates repeatedly.

When the surface of the support plate is formed to have a corrugated cross section, the contact area between the support plate and the material can be minimized, so that the material is easy to slide on the support plate and the material is separated from the support plate. And the material can be more smoothly received on and ejected from the backing plate.

[0011]

Embodiments will be described below with reference to the drawings.

The reversing and conveying device for the fried material comprises a rotating shaft 11.
And a support plate 13 and a support plate 13 attached to the rotating shaft 11 (FIG. 1).

The rotating shaft 11 is disposed at the end of the conveyor CW for conveying the materials W, W... In the width direction of the conveyor CW. However, here, the materials W, W ...
Are cut to a predetermined size and are tofu to be fried materials. The materials W, W... Are neatly arranged on the conveyor belt CW1 of the conveyor CW, and the conveyor rollers CW2, CW3 are driven to rotate. By
It is assumed that the sheet is conveyed in the direction of arrow K1 in FIG. Note that the rotation shaft 11 is disposed below the upper surface of the transport conveyor CW.

The rotating shaft 11 is rotatably supported by a bearing (not shown), and an intermediate portion thereof is formed in a prismatic shape. Further, pinions 11a, 11a are attached to both ends of the rotating shaft 11.

Each pinion 11a meshes with a rack shaft 21 disposed in parallel with the conveyor CW, and each rack shaft 21 is connected to a cylinder 21a. In addition, each rack shaft 21 has a bracket 21b at its tip.
The guide rod 22 is connected via
Each of the rack shafts 21 and the guide rods 22 slidably penetrate the fixed plate 23. However, in FIG. 1, a pair of cylinders 21a, rack shafts 21, guide rods 22 and the like are provided on the left and right corresponding to the pinions 11a, 11a regardless of the illustration. Therefore, if the left and right cylinders 21a, 21a are expanded and contracted simultaneously, the rack shaft 2
1 and 21 move back and forth at the same time,
Can alternately and repeatedly rotate via the rack shafts 21, 21 and the pinions 11a, 11a.

The receiving plate 12 is a plate member having an L-shaped cross section, and is fixed to the rotating shaft 11 using a prism-shaped portion of the rotating shaft 11 (FIGS. 1 and 2). In addition, the receiving plate 12
It is attached to the rotating shaft 11 via a reinforcing member 14 having an L-shaped cross section.

The support plate 13 is a plate material in which the front end (the side in contact with the material W, the same applies hereinafter) is formed on a slope, and the support plate 13 is perpendicular to the receiving plate 12 via the reinforcing member 14. And attached to the rotating shaft 11. The support plate 13 has substantially the same length as the receiving plate 12, and therefore, when the support plate 13 is raised toward the upper conveyor roller CW2 of the transport conveyor CW, the material is W, W... Can be stably received on the receiving plate 12 (two-dot chain line in FIG. 2). The support plate 13 has its front surface formed in a cross-sectional waveform along the direction in which the materials W are received (FIGS. 1 and 3), and is coated with a synthetic resin material 13a such as Teflon (trade name). Processing has been done. In addition, the support plate 13
It may be integrally formed of a synthetic resin material.

A flyer F is disposed below the conveyor CW and the rotating shaft 11 (FIGS. 1 and 4).

The fryer F is an oil tank F1 that fills the heating oil L.
And the materials W, W... In the oil tank F1 by the arrow K2 in FIG.
, K2... As a main member, and a partition frame F3 into which materials W, W... Can be loaded one by one into the chain conveyor F2.
, F3... Are formed. However, each partition frame F3
Are mounted on the chain conveyor F2 independently for each row perpendicular to the traveling direction of the chain conveyor F2, and the bottom of each partition frame F3 is
It is assumed to be a mesh.

The material W charged into each partition frame F3 is drawn into the heating oil L at the position of one of the chain sprockets F2a. The material W is fried while traveling through the heating oil L, and is further guided by the guide sprocket F2b. Oil L at a position past
, And can be processed into fried W1, W1. A guide plate F4 is provided below the chain conveyor F2 so that unprocessed materials W, W... Do not inadvertently flow out of the partition frames F3, F3. Is extended over one end of an oil tank F1 along a chain conveyor F2 which travels obliquely upward by a guide sprocket F2b and a chain sprocket F2c. So, fried W1, W1 ...
By the chain conveyor F2, it can be scraped up along the guide plate F4 and discharged onto the receiving plate F5 arranged below the guide plate F4. The materials W, W... In the heating oil L generally flow out of the partition frames F3, F3. There is little risk of doing this.

Now, the rotating shaft 11 is rotated upward, and the rotating shaft 11 is fixed at the receiving position so that the receiving plate 12 and the supporting plate 13 take an obliquely upward posture (FIG. 2). When the CW is operated, the materials W, W on the conveyor CW are moved.
.. Of the front row are separated from the conveyor belt CW1 by the bending of the conveyor belt CW1 along the upper conveyor roller CW2.
It can travel in three directions and simultaneously drop onto the receiving plate 12 via the support plate 13 (two-dot chain line in FIG. 2, FIG. 1).
At this time, since the materials W, W ... fall down between the receiving plate 12 and the conveyor roller CW2 by sliding on the surface side of the supporting plate 13 positioned so as to connect them, There is no risk of shape loss.

When a row of materials W, W,... Falls on the receiving plate 12, the cylinders 21a, 21a are driven to rotate the rotating shaft 11a downward (in the direction of arrow K4 in FIG. 2). ). However, at this time, the rotating shaft 1
Below 1, the chain conveyor F2 is driven to receive the materials W, W ... and the empty partition frames F3, F3 ...
Shall be prepared.

The rotating shaft 11 rotates downward, and stops at a discharge position where the receiving plate 12 is substantially vertical and the support plate 13 is substantially horizontally downward (FIG. 5). Thus, the materials W, W... On the receiving plate 12 are simultaneously moved to the partition frames F3, F3.
3... (In the direction of the arrow K5 in the figure), and then the chain conveyor F2 is operated to move the partition frames F3 and F3.
3.. Is advanced by one pitch, and the materials W, W.

In the same manner, the rotating shaft 11 is returned to the receiving position, and the materials W, W in the next row on the transport conveyor CW.
.. Are dropped on the receiving plate 12 and the rotating shaft 11 is rotated to the discharge position, so that the material W on the transport conveyor CW,
W ... can be continuously discharged into the partition frames F3, F3 ... of the flyer F.

When the materials W, W... Fall on the receiving plate 12, the lower surface which has been in contact with the conveyor belt CW1 is in contact with the support plate 13. When it rotates and falls into the partition frames F3, F3,..., It is upside down. In general, the water in the materials W, W... Tends to move downward and stay on the conveyor CW, but when the materials W, W. Can be easily released to the outside, and the drainage of the materials W, W... Can be improved.

In such a system, the traveling speed of the chain conveyor F2 of the flyer F is generally determined first. The chain conveyor F2 is made of material W,
This is because the operation must be performed so as to match the required processing time of W. Therefore, the rotating shaft 11 determines its operation frequency in accordance with the traveling speed of the partition frames F3, F3,... Driven by the chain conveyor F2, and the transport conveyor CW rotates the receiving shaft by rotating the rotating shaft 11. After confirming that the plate 12 and the support plate 13 are at the predetermined receiving positions, it is preferable to perform the intermittent operation. Such a series of controls, for example,
The cylinders 21a, 21a are driven by the output of an encoder that detects the traveling distance of the chain conveyor F2, and the transport conveyor CW is intermittently driven by a predetermined pitch by the output of a sensor that detects the position of the receiving plate 12 or the support plate 13. It can be easily realized.

In the above description, any linear drive source can be used as the drive source for repeatedly rotating the rotation shaft 11 instead of the cylinders 21a, 21a. Further, a reversible rotary drive source such as a motor connected to the rotary shaft 11 via an appropriate gear mechanism or directly may be used.

[0028]

As described above, according to the present invention, the rotating shaft disposed at the end of the conveyor, the receiving plate and the supporting plate attached to the rotating shaft are provided, and the rotating shaft is received at the receiving position. The material from the conveyor can be received on a receiving plate via a support plate and then discharged upside down and discharged by rotating it back and forth between the and the discharge position. There is no need to use a robot or a suction pad that tends to cause problems, and there is an excellent effect that the material can be efficiently inverted and charged into the flyer while having an extremely simple configuration.
