The packed food is collected as a final product in the product collection section 19 .

In the food processing system 10 of the present embodiment, a plurality of (five in the present embodiment) geared motors 100 are employed as driving devices for the food processing apparatus. The configuration of geared motor 100 will be described below with reference to FIGS.

The geared motor 100 of this embodiment includes a housing 101 defining an outer surface, a drive unit 105 housed in the housing 101 and having a rotary drive shaft 107 that rotates by electric power, and a driving force applied to the food processing apparatus outside the housing 101. a speed reduction mechanism 109 housed in the housing 101 for transmitting the rotation of the rotary drive shaft to the output shaft 103 in a reduced speed; and a brake mechanism 110 for braking. In the geared motor 100 of the present embodiment, sufficient sealing is applied to drive portions exposed to the outside of the housing 101 in order to prevent foreign matter from leaking grease from the inside of the housing 101 . In addition, grease for food machinery is enclosed as grease.

The outer surface of the housing 101 of the geared motor 100 is coated with a coating film having a color that is not used for food and the surrounding environment. In this embodiment, the surrounding environment is the floor and walls of a factory, and no blue pigment is used. Also, the food to be treated does not contain blue. In this embodiment, the paint film covering the outer surface of the housing 101 contains urethane resin as a main component and contains a blue pigment (that is, a pigment consisting only of blue). In other words, the outer surface of the housing 101 is painted blue. The blue pigment may be inorganic, organic, natural or synthetic as long as it can be used as a pigment that develops blue color. For example, as blue pigments, inorganic pigments such as ultramarine blue, cobalt blue and Prussian blue, and organic pigments such as phthalocyanine blue, alkali blue and indanthrone blue are suitably used. When the food is made from rice or wheat flour, the white color is not used for the coating film because the white color is similar to the white color. Also, if the factory floor is green, the green color is not used for the paint film. A coating film may also be formed on the inner surface of the housing 101 .

Moreover, in this embodiment, the coating film further contains an antibacterial agent for suppressing the propagation of germs. As antimicrobial agents, inorganic antimicrobial agents containing, for example, silver or copper may be selected. Specifically, the inorganic antibacterial agent is formed by heating at least one of silver nitrate, silver halide, and silver oxide together with a glass raw material, and then pulverizing to form particles having an average particle size of about 0.01 to 20 μm. is. By including such antibacterial particles in the coating film, the coating film can exhibit an antibacterial action.

As shown in FIG. 6, a drive section 105 driven by power supplied from a power supply section 106 connected to an external power supply is provided at a substantially central portion of the geared motor 100 . The drive unit 105 includes a rotary drive shaft 107 that rotates with electric power. The drive unit 105 is connected to both the speed reduction mechanism 109 and the brake mechanism 110 . The reduction mechanism 109 includes a hypoid gear that can mesh with the tip of the rotary drive shaft 107 , and is configured to reduce the rotation of the rotary drive shaft 107 at a predetermined gear ratio and output it to the output shaft 103 . The output shaft 103 is a key-shaped cavity, and is configured to insert an input shaft (not shown) as an input portion of the food processing apparatus to output rotational driving force to the food processing apparatus. On the other hand, the brake mechanism 110 is configured to act on the drive unit 105 to brake the rotation of the rotary drive shaft 107 when the geared motor 100 is in a non-excited state.

7 and 8, the brake mechanism 110 includes a brake shaft 111 connected to the rotary drive shaft 107 of the drive unit 105, brake linings 112 fixed to the brake shaft 111, and brake linings 112. A brake plate 113 movably supported by the housing 101 between a braking position in pressure contact and a braking release position separated from the brake lining 112; and a brake release handle 115 connected to the brake plate 113 for moving the brake plate 113 from the brake position to the brake release position.

More specifically, the brake shaft 111 is connected to the rotary drive shaft 107 and extends in the axial direction so as to be coaxial with and integrally rotated with the rotary drive shaft 107 . A brake lining 112 is fixed to the outer peripheral side of the brake shaft 111 . The brake lining 112 is an annular body made of a friction material extending in the circumferential direction of the brake shaft 111, and exerts a braking force against an object to be pressed against. The brake plate 113 is an annular body made of a magnetic metal and arranged to face the brake lining 112 on one side in the axial direction. The braking plate 113 is supported by three guide pins 117 so as to be axially floatable with respect to the housing 101 (see FIGS. 7 and 8). That is, the brake plate 113 is supported so that a gap can be formed between one axial surface and the inner surface of the housing 101 or between the other axial surface and the brake lining 112 . A urging spring 114 is accommodated in a depression in the inner surface of the housing 101 . The urging spring 114 abuts on one axial surface of the braking plate 113 in a compressed state and acts to urge the braking plate 113 against the brake lining 112 . A coil 116 is arranged in a concave portion of the inner surface of the housing 101 so as to face one surface of the braking plate 113 in the axial direction. A brake release handle 115 is rotatably supported on the outer surface of the housing 101 .

3 and 8, the brake release handle 115 includes one operation shaft 115a, a branch shaft 115b bifurcated from the operation shaft 115a, and a base end of the branch shaft 115b and a brake plate inside the housing 101. A connecting shaft 115c that connects 113 is provided. The brake release handle 115 can be tilted about the connecting shaft 115c to both sides in the axial direction of the brake shaft 111 within a range of about 16 degrees (it can be tilted about 8 degrees to one side). Further, the connecting shaft 115c is configured to move the brake plate 113 in the axial direction as the brake release handle 115 rotates.

In the non-excited state of geared motor 100 shown in FIG. The pressure contact between the brake plate 113 and the brake lining 112 generates a braking force to the rotary drive shaft 107 . When the geared motor 100 is in an excited state, a current flows through the coil 116 to generate a magnetic force, and the brake plate 113 is magnetically pulled toward the coil 116 . As a result, the brake plate 113 is separated from the brake lining 112 and the braking of the rotary drive shaft 107 is released.

The braking of the rotary drive shaft 107 can also be released by tilting the brake release handle 115 while the geared motor 100 is in a non-excited state. As shown in FIG. 9, the tilting of the brake release handle 115 causes the brake plate 113 to move away from the brake lining 112, and the braking of the rotary drive shaft 107 is released. That is, by operating the brake release handle 115, it is possible to manually release the brake while the geared motor 100 is in the non-excited state.

Hereinafter, the effects of the food processing system 10 of one embodiment of the present invention will be described.

According to the food processing system 10 of the present embodiment, the outer surface of the geared motor 100 is formed with a blue coating film that is not used for food and the surrounding environment. In particular, blue pigments are most suitable for the food processing system 10 because they are rarely used in food and foreign substances mixed in food can be visually detected easily. As a result, when the coating film peels off from the geared motor 100, the color of the foreign matter can be distinguished and found, and it can be immediately determined whether or not the foreign matter is caused by the geared motor 100.例文帳に追加Therefore, the food processing system 10 of the present invention facilitates the discovery of foreign matter caused by the geared motor 100 and the identification of the location where the foreign matter is generated.

Further, the food processing system 10 of the present embodiment is provided with a brake release handle 115 for releasing the braking of the rotary drive shaft 107 when the geared motor 100 is in a non-excited state. As a result, the user can safely and speedily perform maintenance of the geared motor 100 and restoration work in the event of a power failure or the like in the line of the food processing system 10 . Further, by setting the tilting angle of the brake release handle 115 to one side at 8 degrees, the braking of the rotary drive shaft 107 can be prevented from being suddenly released, and the braking of the rotary drive shaft 107 can be easily released. is possible.

The present invention is not limited to the above-described embodiments and modifications, and can be implemented in various forms within the technical scope of the present invention.
