[Technical field]

[0001] The present invention relates to a structure for preventing food from falling off a conveyor for a fryer. [Background technology]

[0002] A conventional fryer conveyor is known to have the configuration shown in Fig. 6. This automatic fryer conveyor has a caterpillar conveyor 2 provided below a food material input section 1, a lower net conveyor 4 provided with a required gap 3 from the rear end of the caterpillar conveyor 2, and an upper net conveyor 5 provided above the caterpillar conveyor 2 and the lower net conveyor 4, and these conveyors are installed in an oil tank 7 of a fryer 6 (see Patent Document 1). In addition, reference numeral 8 in FIG. 6 denotes a discharge portion for the fried food materials.

[0003] The reason why a caterpillar conveyor 2 with multiple caterpillar plates arranged in parallel is provided below the food inlet section 1 is that when the food being fed is soft and heavy, such as fried chicken, if a net conveyor were used, the food would get stuck in the net and create a mesh-like pattern. Furthermore, if only the caterpillar conveyor 2 is provided up to the discharge portion 8, there will be an inconvenience that the oil residue and the like will not fall down. Therefore, a caterpillar conveyor 2 is provided in the first half of the conveyor, and a net conveyor 4 made of a net is provided midway through to drop oil residue and the like downwards.

[0004] The gap 3 is provided between the rear end of the caterpillar conveyor 2 and the front end of the lower net conveyor 4 in order to allow the passage of protruding portions (not shown) which are provided at predetermined intervals to transport food materials to the net of the lower net conveyor 4. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 8-299199 A [Patent Document 2] Patent No. 6164933 Summary of the Invention [Problem to be solved by the invention]

[0006] This conventional automatic fryer conveyor has a problem in that thin sliced ​​foodstuffs, such as vegetables, may fall through the gap 3. In this case, in the case of a fryer that employs a water flow filtration system in which fried food particles 44 and the like fall into a water layer 43 and are collected in a draft box 45, as shown in FIG. 5, and the collected fried food particles 44 and the like are discharged together with the wastewater (see Patent Document 2), there is a problem in that the fallen ingredients block the draft box 45, and as a result, the water cannot flow, the water level rises, and there is a risk of the oil in the oil layer 42 overflowing.

[0007] Therefore, in the conventional example, there is a problem that must be solved by providing some kind of system that prevents food ingredients from falling through the gap 3 between the rear end of the caterpillar conveyor 2 and the front end of the lower net conveyor 4. [Means for solving the problem]

[0008] The gist of the present invention for solving the problems of the conventional example is a structure for preventing food from falling on a fryer conveyor, comprising at least a caterpillar conveyor having a plurality of caterpillar plates arranged in parallel, a caterpillar conveyor drive shaft provided at the rear end of the caterpillar conveyor, a first gear provided at one end of the caterpillar conveyor drive shaft, a first chain connected to the first gear, a motor for rotating the first chain, a lower net conveyor formed of a net and provided with a required gap from the rear end of the caterpillar conveyor, and a lower net conveyor driven shaft provided at the tip of the lower net conveyor, wherein a fall prevention shaft is rotatably disposed in the gap between the rear end of the caterpillar conveyor and the tip of the lower net conveyor, a second gear is provided at one end of the fall prevention shaft, and the second gear and the first gear are linked by a second chain to rotate the fall prevention shaft.

[0009] In addition, the first gear and the second gear are linked by the second chain, so that the conveying direction of the caterpillar conveyor and the rotation direction of the fall prevention shaft are configured to be the same; It includes. Effect of the Invention

[0010] According to the food ingredient falling prevention structure for a fryer conveyor of the present invention, by disposing a fall prevention shaft in the gap between the rear end of the caterpillar conveyor and the front end of the lower net conveyor, the inconvenience of food ingredients falling through the gap can be prevented. In this case, since the fall prevention shaft is arranged to be freely rotatable, it has the excellent effect of preventing inconveniences such as foodstuffs becoming entangled in the fall prevention shaft or foodstuffs becoming stuck in the gap between the shaft and the conveyor.

[0011] By linking the first gear and the second gear with the second chain, the conveying direction of the caterpillar conveyor and the rotation direction of the fall prevention shaft are configured to be the same, which provides various excellent effects, such as allowing the transported food ingredients to move smoothly and more effectively preventing the food ingredients from falling and becoming entangled in the fall prevention shaft.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Next, an embodiment of the present invention will be described with reference to the drawings. First, in Fig. 1 to Fig. 4, reference numeral 11 denotes a structure for preventing food from falling on a fryer conveyor, and this structure for preventing food from falling 11 includes a caterpillar conveyor 12, a drive shaft 13 for the caterpillar conveyor provided at the rear end of the caterpillar conveyor 12, a first gear 14 provided at one end of the drive shaft 13 for the caterpillar conveyor, a first chain 15 connected to the first gear 14, a motor 16 for rotating the first chain 15, and a required gap from the rear end of the caterpillar conveyor 12. The caterpillar conveyor 12 has a lower net conveyor 17 with a gap 19 therebetween, and a lower net conveyor driven shaft 18 provided at the tip of the lower net conveyor 17. A fall prevention shaft 20 is rotatably arranged in the gap 19 between the rear end of the caterpillar conveyor 12 and the tip of the lower net conveyor 17. A second gear 21 is provided at one end of the fall prevention shaft 20. The second gear 21 and the first gear 14 are linked by a second chain 22 to rotate the fall prevention shaft 20.

[0014] The caterpillar conveyor 12 is configured so that a plurality of long, narrow caterpillar plates (not shown) are arranged in parallel in an endless manner and are freely rotatable. The caterpillar conveyor 12 is provided with a caterpillar conveyor driven shaft 23 at its leading end and a caterpillar conveyor drive shaft 13 at its trailing end. The caterpillar conveyor driven shaft 23 and the caterpillar conveyor drive shaft 13 are respectively provided across the frame portions 47, 47 and are axially supported so as to be freely rotatable. Reference numeral 24 in FIGS. 1 and 2 denotes a chain guide, reference numeral 25 denotes a heater, and reference numeral 26 in FIG. 1 denotes a heater guide. Moreover, above the tip end of the caterpillar conveyor 12, as shown in FIG.

[0015] As described above, the caterpillar conveyor drive shaft 13 is provided at the rear end of the caterpillar conveyor 12, and a first gear 14 is provided at one end of the caterpillar conveyor drive shaft 13.

[0016] As shown in Figures 2 and 4, a first chain 15 is rotatably connected to the first gear 14, and as shown in Figure 2, the first chain 15 is connected to a motor 16 so that the first chain 15 rotates when driven by the motor 16. 2 and 4, the motor shaft gear 16a is rotated by the drive of the motor 16, and the rotation of the motor shaft gear 16a rotates the first chain 15. The rotation of the first chain 15 rotates the first gear 14 and also rotates the caterpillar conveyor drive shaft 13. Furthermore, the rotation of the caterpillar conveyor drive shaft 13 rotates the caterpillar conveyor 12 in the conveying direction (the direction of the arrow C) to convey the ingredients inserted from the ingredient insertion section 27.

[0017] The reason for providing a caterpillar conveyor 12 below the food inlet section 27 is the same as that stated in the background art section: when the food being fed is soft and heavy, such as fried chicken, if a net conveyor were used, the food would get caught in the net and create a mesh-like pattern.

[0018] The lower net conveyor 17 is provided with a required gap 19 from the rear end of the caterpillar conveyor 12. The reason for providing a gap 19 between the rear end of the caterpillar conveyor 12 and the front end of the lower net conveyor 17 is to allow the food ingredients to pass through protruding portions (not shown) that are provided at predetermined intervals to transport food ingredients to the net of the lower net conveyor 17.

[0019] The lower net conveyor 17 is formed in a mesh shape using chocolate netting, wire belts, or the like (not shown), and is provided in an endless manner so as to be freely rotatable. The lower net conveyor 17 is provided with a lower net conveyor driven shaft 18 at its leading end, and is provided with a lower net conveyor drive shaft 28 at its rear end, inclining upward from the middle. The lower net conveyor driven shaft 18 and the lower net conveyor drive shaft 28 are respectively provided across the frame portions 47, 47 and are axially supported so as to be freely rotatable. 1 and 2, reference numeral 29 denotes a first net guide, and reference numeral 30 denotes a second net guide. Reference numeral 31 in Fig. 1 denotes a heater, and reference numeral 18a denotes a roller provided on the drive shaft 28 for the lower net conveyor. As shown in FIG. 2, above the rear end of the lower net conveyor 17, a food material discharge section 32 is provided.

[0020] 2, reference numeral 34 denotes a motor, and reference numeral 35 denotes a drive gear. Drive of motor 34 rotates drive gear 35, and the rotation of drive gear 35 rotates connected chain 36. The rotation of chain 36 rotates lower net conveyor drive shaft 28, and the rotation of lower net conveyor drive shaft 28 rotates lower net conveyor 17 in the conveying direction (direction of arrow C), thereby conveying ingredients.

[0021] As shown in FIG. 2, an upper net conveyor 33 is provided above the caterpillar conveyor 12 and the lower net conveyor 17. In addition, in the plan view in which part of the flyer conveyor is omitted in FIG. 1, the upper net conveyor 33 is omitted in order to show the caterpillar conveyor 12 and the lower net conveyor 17. Reference numeral 12 in Fig. 1 indicates the range in the conveying direction (arrow C direction) and width direction of the caterpillar conveyor 12 shown in light ink. Reference numeral 17 in Fig. 1 indicates the range in the conveying direction (arrow C direction) and width direction of the lower net conveyor 17 shown in light ink.

[0022] As shown in FIG. 2, the upper net conveyor 33 has an upper net conveyor driven shaft 37 at its leading end, and is inclined upward from the middle to have an upper net conveyor drive shaft 38 at its trailing end.

[0023] Drive gear 35 rotates when motor 34 is driven, and the rotation of drive gear 35 rotates meshing gear 39, which in turn rotates connected chain 40. The rotation of chain 40 rotates upper net conveyor drive shaft 38, and the rotation of upper net conveyor drive shaft 38 rotates upper net conveyor 33 in the conveying direction (arrow C direction) to convey food ingredients. In other words, food ingredients move between upper net conveyor 33 and lower net conveyor 17.

[0024] The fall prevention shaft 20 is rotatably disposed in the gap 19 between the rear end of the caterpillar conveyor 12 and the front end of the lower net conveyor 17. The fall prevention shaft 20 is provided across the frame portions 47, 47 and is rotatably supported.

[0025] A second gear 21 is provided at one end of the fall prevention shaft 20, and a second chain 22 is provided between the second gear 21 and the first gear 14. In other words, when the first gear 14 rotates, the second gear 21 rotates via the second chain 22, and the fall prevention shaft 20 rotates.

[0026] In this manner, since the fall prevention shaft 20 is arranged to be freely rotatable, problems such as foodstuffs getting entangled in the fall prevention shaft 20 or foodstuffs getting stuck in the gap between the fall prevention shaft 20 and the conveyor can be eliminated. In addition, by linking the first gear 14 and the second gear 21 with the second chain 22, the conveying direction of the caterpillar conveyor 12 and the rotation direction of the fall prevention shaft 20 are configured to be the same. Therefore, the conveyed food materials can move smoothly, and the food materials can be more effectively prevented from falling and from getting tangled in the fall prevention shaft 20.

[0027] Next, a water flow filtration system that employs the structure for preventing food from falling from a fryer conveyor of the present invention will be briefly described. 5 has an oil layer 42 in the upper part and a water layer 43 in the lower part. Fried food residue 44 and the like are dropped into the water layer 43 and collected in a draft box 45, and the collected fried food residue 44 and the like are discharged together with wastewater via a drain pipe 46. Therefore, by adopting the food material drop prevention structure 11 of the fryer conveyor of the present invention, food material can be prevented from falling through the gap 19 between the conveyors, so the problem of blocking the draft box 45 does not occur, and the problem of the water not flowing and the water level rising, causing the oil in the oil layer 42 to overflow, can be prevented.

[0028] The food ingredient drop prevention structure 11 for the fryer conveyor constructed as described above has a drop prevention shaft 20 disposed in the gap 19 between the rear end of the caterpillar conveyor 12 and the leading end of the lower net conveyor 17, thereby preventing the problem of food ingredients falling through the gap 19. In this case, since the fall prevention shaft 20 is arranged to be freely rotatable, inconveniences such as foodstuffs getting entangled in the fall prevention shaft 20 or foodstuffs getting stuck in the gap between the conveyors 12, 17 can be prevented.

[0029] By linking the first gear 14 and the second gear 21 with the second chain 22, the conveying direction (direction of arrow C) of the caterpillar conveyor 12 and the rotation direction of the fall prevention shaft 20 are configured to be the same, which allows the food being conveyed to move smoothly and more effectively prevents the food from becoming entangled in the fall prevention shaft 20.
