Description

  The present invention relates to a food conveyor. More specifically, the present invention relates to a food conveyor apparatus that moves a food material while moving it in oil or hot water in a liquid tank while being moved by a sorting moving plate attached to an endless conveyor that rotates.

  Food materials such as croquettes and tonkatsu materials are fried in oil to make food, or raw soba and raw udon are made into food with hot water using an endless conveyor. Various food conveyor devices are known.

  In general, in order to process the food material, the food material is moved horizontally in a state where it passes through a liquid tank that is an oil tank or a hot water tank, and the croquette is fried in an appropriate time or the udon is boiled up When such a material is turned into food, it is necessary to automatically lift it from the liquid tank.

  Therefore, conventionally, for example, a horizontal endless conveyor for moving the liquid tank in the horizontal direction using two net endless conveyors, and a diagonal provided for pulling up the food product from the liquid tank upward. Food conveyors that are combined with a conveyor are known. This food conveyor device is a system in which food materials are moved on a net conveyor. (Prior art 1)

  In addition, as a food conveyor device that uses a single endless conveyor to pull up the food product from the liquid tank upward, the entire endless conveyor on the net is at a certain angle with respect to the horizontal liquid level of the liquid tank. There has been known an apparatus having a configuration in which a material made of food is automatically pulled up from the liquid after the material is immersed in a liquid tank, after being provided in a slanted shape (conventional technique 2).

  However, when two endless conveyors are used as in the prior art 1, it is necessary to dispose the drive source to each of them, and a device for synchronizing the speeds of the horizontal endless conveyor and the oblique endless conveyor, or one of which is an emergency stop In such a case, a device for stopping the other is required. For this reason, the configuration of the apparatus is complicated, and there is a problem that the operation and maintenance are troublesome.

  Further, since the liquid in the liquid tank is moved by the net conveyor as in the prior art 2, the temperature difference of the liquid changes depending on the depth of the liquid tank, and there is a problem that uneven frying is likely to occur.

In order to solve the above problems, one endless chain, a chain support for supporting the endless chain's circular movement, a motor for driving the endless chain, a plurality of segmented moving plates that can be attached to and detached from the endless chain, and a liquid tank And a food conveyor device having a heating source,
One endless chain performs endless rotational movement along the outer peripheral surface of the chain support portion, and the chain support portion includes a horizontal moving portion in which the endless chain moves horizontally and the section moving plate moves in the liquid tank, and an endless chain The food conveyor apparatus is characterized in that it moves endlessly and the section moving plate also has an inclined surface moving part that moves away from the liquid tank in an inclined shape and rotates endlessly.

  Furthermore, when each section moving plate-like body applies a certain load to the movement of the endless chain, the movement of the endless chain is automatically stopped and automatically connected when the load is removed. The food conveyor apparatus described is proposed.

  According to the present invention, by using a single endless chain and attaching a plurality of section moving plates to the endless chain in a detachable manner, the horizontal moving portion and the slope moving portion are continuously folded from the single endless chain. The section moving plate is moved through the curved section, and each section moving plate is passed through the liquid tank in the horizontal moving section to process the food material, while the slope moving section conveys the processed food obliquely upward from the liquid tank. Can be put out.

  Therefore, since there is one endless chain, only one drive motor as a drive source is required, and since the configuration is simple, there is an advantage that operation and maintenance are easy.

  Furthermore, unlike the prior art 2, the liquid tank is not slanted, and there is no shallow depth in the liquid tank and the depth is uniform, so that there is little heating unevenness due to the movement of the food material, and the liquid in the liquid tank There is an advantage that heating and temperature operation become easy.

  Furthermore, according to the second aspect of the present invention, when one section moving plate is stopped due to some trouble, such as being caught by an operator or the like, the movement of the endless chain is automatically stopped, thereby improving safety. did.

The rotating shaft (driven shaft) 22 of the driving roller 21 is connected to the driving shaft 30 of the driving motor 3 by the connecting portion 7, and transmits the rotation of the driving motor 3 to the endless link chain 1 (see FIG. 5). Instead of the driving roller 21, a sprocket, a gear, or the like may be used. In the vicinity of the rotating portions 23a and 23b of the moving support frame 20, only the outer guide plate 20a is disposed up to the vicinity of the rotation centers of the driving roller 21 and the driven roller, but the inner guide plate 20b is as shown in FIG. It is provided only up to the front of the driving roller 21. Reference numeral 24 shown in FIG. 6 denotes a bracket. The chain support portion 2 is attached to the apparatus main body by a bracket 24.

  As shown in FIG. 5, the connecting portion 7 has a thick cylindrical inner connecting body 71 fixed to the drive shaft 30 of the driving motor 3, and a driving roller 21 side provided on the side peripheral surface of the inner connecting body 71. The outer cover 74 is fixed to the rotating shaft (driven shaft) 22, and a plurality of plungers 70 provided at equal intervals are fixed to the outer cover 74. Two plungers 70 located at 180 ° facing positions are fixedly provided. The tip of the plunger 70 is formed in a conical protrusion shape. Concave grooves 72 corresponding to the number of the plungers 70 are formed on the cylindrical side peripheral surface of the inner coupling body 74, and in this embodiment, two concave grooves 72 separated by 180 degrees are formed.

  The tips of the conical protrusions of the two plungers 70 provided on the outer cover body 74 of the connecting portion 7 are fitted in the concave grooves 72 of the inner connection body 74 at the corresponding positions. The inner connection body 71 slides by a bear link 73 in other parts.

  About 3/4 on one side of the ellipse direction of the chain support portion 2 is formed as a horizontal moving portion 201 in which the moving support frame 20 is provided horizontally, and the remaining about 1/4 is 20 degrees to 30 degrees from the horizontal. It is formed as the slope moving part 202 formed in the shape of a slope heading upward. Reference numeral 203 denotes a bent portion of the moving support frame 20. The slope moving unit 202 changes its direction by 180 degrees at the rotation unit 23b located at the uppermost position from the ascending slope, becomes a descending slope, and continuously moves to the horizontal moving unit 201.

  A liquid tank 5 is provided around the horizontal moving portion 201 of the moving support frame 20 of the chain support portion 2. In the state where the endless chain 1 is moving along the moving support frame 20 that is the horizontal moving unit 201, the segment moving plate 4 attached to the endless chain 1 moves in the liquid tank 5.

  A heating source 6 including a plurality of heaters is provided at an appropriate bottom surface position in the liquid tank 5 to heat edible oil or water put in the liquid tank 5. 52 is the most upstream part where the sorting moving plate 4 attached to the endless ring chain 1 of the liquid tank 5 starts to enter. The bottom surface of the one end side in the liquid tank 5 has a tanned portion 50 formed as a large net-like or parallel rod-shaped bottom surface, and the tanned portion 50 does not need a ceiling or the like submerged in oil or hot water. Things are collected. A waste oil valve 51 is provided at the bottom of the tanned portion 50.

  The finishing portion 8 is disposed below the climbing slope plate 80 provided around the climbing slope of the slope moving portion 202 of the moving support frame 20 of the chain support portion 2 and the uppermost end portion where the climbing slope plate 80 is opened. The shooter 81 is provided with an inclined shooter and an oil draining portion 82 made of a net-like body disposed under the shooter 81. A downward inclined plate 83 is provided around the downward inclination of the slope moving portion 202 of the moving support frame 20 to support the lower side of the section moving plate 4. The inclination of the climbing inclined plate 80 and the descending inclined plate 83 is the same as the inclination of the slope moving unit 202.

  Next, the operation of the edible conveyor apparatus according to the embodiment of the present invention will be described. In the liquid tank 5 of this edible conveyor device, water is put when boiled udon and soba, and edible oil is put when frying croquettes and cutlets. The control panel 91 is actuated to heat the heating source 6 so as to obtain oil or hot water of suitable temperature for cooking. In the description of this embodiment, the liquid tank 5 is an edible conveyor device that raises an oil tank, croquettes, tonkatsu and the like.

  Next, the drive motor 3 is driven by the control panel 91, the drive roller 21 is rotated through the drive shaft 30, the connecting portion 7, and the driven shaft 22, and the endless link chain 1 is rotated in one direction at a low speed. In this embodiment, the endless link chain 1 has a structure in which a large number of oval links are connected to each adjacent link with a 90-degree angle shift. The endless long hole 20c can be engaged and moved. Further, the link of the endless link chain 1 can move smoothly even at the bent portion 203 around 30 degrees above and below the horizontal moving portion 201 and the slope moving portion 202 of the support frame 20 for movement.

  In the connecting portion 7, the tips of the conical protrusions of the two plungers 70 provided on the outer cover body 74 are fitted in the concave grooves 72 of the inner connection body 74 at the corresponding positions. Since 74 and the inner coupling body 71 are slid by the bear link 73 in other portions, the rotation of the drive shaft 30 of the drive motor 3 is normally driven by the engagement between the plunger 70 and the concave groove 72. The power is transmitted to 22 and the driving roller 21 rotates.

  However, if some load is applied to the movement of the endless link chain 1, for example, the attached segment moving plate 4 is caught by something and a load is applied to the rotating shaft (driven shaft) 22 on the drive roller 21 side, the plunger 70 is moved into the concave groove 72. And the rotational force of the drive shaft 30 of the drive motor 3 is not transmitted to the driven shaft 22, and the endless link chain 1 stops. Further, when the load applied to the endless link chain 1 is removed after a lapse of time, the tip of the conical protrusion of the plunger 70 is again fitted into the concave groove 72 of the inner connecting body 74 and automatically coupled. The rotation of the drive shaft 30 of the drive motor 3 is transmitted to the driven shaft 22 and the drive roller 21 starts to rotate.

  On the endless link chain 1, the segment moving plate 4 is attached by an attachment portion 40 at an appropriate interval. The section moving plate 4 enters the liquid tank (oil tank) 5 around the horizontal moving section 201 of the moving support frame 20 of the chain support section 2 and moves downstream from the most upstream section 52 of the liquid tank 5. The oil before moving the croquettes and tonkatsu into the oil between the moving hills 4 is introduced. The input material moves while being fried with oil of appropriate temperature, enters the finishing portion 8 provided at the most downstream, contacts the climbing slope plate 80, and the section moving slope in which the lower side contacts the climbing slope plate 80. 4, the climbing inclined plate 80 is raised, falls from the open end to the shooter 81, slides on the shooter 81, and stops at the oil draining portion 82. At this time, the material such as croquettes is a food called croquettes fried in oil. The section moving slope 4 is attached to the endless link chain 1 that circulates endlessly, and enters the oil from the uppermost stream portion 52 of the liquid tank (oil tank) 5 again, and inputs the raw material before the new croquette or tonkatsu is fried. . By repeating this, a large number of croquettes and tonkatsu can be fried appropriately within a short time.

  When a large number of raw materials such as croquettes and tonkatsu are fried, impurities such as clothes and tops begin to sink in the oil tank 5, but they fall down from the net of the tanned portion 50 and can be easily removed. Further, when waste oil is used by using oil for a long time, it is discarded from the waste oil valve 51.

  It can be expected to be used in food stores that provide foods fried in oil such as croquettes and tonkatsu, and food stores that provide foods that are boiled in hot water such as soba, udon, and dumplings.
