The hoist apparatus for food according to the present invention comprises: a driving unit having a driving wheel provided on a rail for moving a hoist unit to provide a traveling function, and a driving motor mounted on the supporting frame to provide rotational force to the driving wheel; And a second box member surrounding the driving motor so as not to be exposed to the outside.

The first box member and the second box member are preferably made of a stainless steel material.

The food hoist apparatus according to the present invention may further include a foreign matter receiving plate fixed to the support frame so as to be positioned below the drive wheel.

The first box member and the second box member may be watertightly sealed.

The hoist and the driving unit may be provided with a food lubricant.

The hoist apparatus for food according to the present invention comprises a chain box for receiving the chain, and the upper end of the chain box is fixed to the first box member.

A drain bolt may be provided on the lower end surface of the chain box.

The food hoist apparatus according to the present invention may further include a corrugated pipe which surrounds the chain at an upper portion of the hook and has an upper end fixed to a lower surface of the first box member.

The food hoist apparatus according to the present invention has the following effects.

First, oil and foreign substances can be prevented from falling into food during operation by a structure in which various driving parts are enclosed by a box member.

Secondly, since it is possible to freely clean water for the hoist due to the characteristic of having a box member made of stainless steel, it can be effectively applied to a food manufacturing environment with high moisture because it has excellent rust prevention performance.

Third, it is possible to prevent the foreign material generated from the driving wheel or the like from falling into the food, thereby further improving the hygiene.

Fourth, lubricant for food, which is not harmful to human body, and food grease are adopted, and hygiene can be further enhanced.

The driving unit 120 includes a driving wheel 125 that extends over a part of the rail of the hoist unit to provide a driving function and a driving motor 121 mounted on the supporting frame 100 to provide a driving force to the driving wheel 125. [ Respectively.

In the support frame 100, a foreign substance receiving plate 150 is provided immediately below the driving wheel 125. The foreign substance receiving plate 150 prevents various foreign substances such as rust falling upon contact between the driving wheel 125 and the rail from falling onto the food.

The first box member 112 encloses the hoisting motor 111 in four directions without being exposed to the outside, and is made of a stainless steel metal box in consideration of hygienic, waterproof, rust-proof, and aesthetic. A flange 112a is formed around the periphery of the first box member 112. The flange 112a of the first box member 112 is bolted to the first vertical plate 101 fixed to the support frame 100 so that the first box member 112 is detachably fixed to the hoist device . At this time, it is preferable that the flange 112a of the first box member 112 and the first vertical plate 101 are sealed to be waterproof.

A hoist controller box (not shown) is installed at a position opposite to the first box member 112 on the support frame 100 to accommodate various electric / electronic components (for example, fuses, magnets, transistors, transformers, etc.) (113). The hoist controller box 113 is fastened to the third vertical plate 103 fixed to the support frame 100 by bolts and fixed to the first vertical plate 101. [ The hoist controller box 113 can be selectively opened by an opening / closing cover 114 coupled by a fastening means such as a conventional 'cicada ring' to provide convenience of disassembly in maintenance. A sealing member (not shown) for waterproofing is interposed between the edge of the opening / closing cover 114 and the hoist controller box 113. The hoist controller box 113 and the opening / closing cover 114 are made of stainless steel.

The second box member 122 encloses the driving motor 121 of the driving unit 120 without being exposed to the outside and is made of a stainless steel metal box in consideration of sanitary property, waterproof property, rust prevention property, and aesthetic appearance. A flange 122a is formed around the edge of the second box member 122. [ The flange 122a of the second box member 122 is bolted to the second vertical plate 102 disposed at the upper portion of the first vertical plate 101 so that the second box member 122 is detached and attached to the hoist unit It can be fixed as much as possible. At this time, it is preferable that the flange 122a of the second box member 122 and the second vertical plate 102 are sealingly watertight.

A driving unit controller box 123 for storing various electric / electronic parts related to the operation of the driving unit 120 is provided at a position opposed to the second box member 122 on the supporting frame 100. The driving unit controller box 123 is bolted to the fourth vertical plate 104 located at the upper portion of the third vertical plate 103 and opposed to the second vertical plate 102 and fixed. The drive unit controller box 123 can be selectively opened by an opening / closing cover 124 that is coupled by a fastening means such as a conventional 'cicada ring' to provide convenience of disassembly in maintenance. The driving unit controller box 123 and the opening and closing cover 124 are made of stainless steel and a sealing member (not shown) for waterproofing is interposed between the edge of the opening and closing cover 124 and the driving unit controller box 123.

In the present invention, each part made of stainless steel preferably meets IP55 dust protection degree.

A chain 131 hoisted by a hoisting motor 111 and a hook 130 installed at an end of the chain 131 so as to hang the load, The driving wheel 125 and various bearings (not shown) are preferably made of stainless steel.

Lubricant such as food-grade lubricating oil or food grade grease is provided to the portion where the lubricating treatment is required in the hoist 110 and the driving portion 120. [ At this time, it is desirable that the lubricant satisfies the lubricant specification for NSF-H1 food machine which is less harmful to human body.

The chain 131 is accommodated in the inner space of the chain box 160 during hoisting operation of the hoist 110. At this time, the upper end of the chain box 160 is fixed to the lower surface of the support frame 100 in order to prevent the occurrence of foreign substances and the generation of noise.

As shown in FIG. 3, a drain bolt 170 for discharging water and the like stored in the chain box 160 to the outside is removably installed on a lower end surface of the chain box 160.

A corrugated pipe 140 surrounding the chain 131 is provided at an upper portion of the hook 130 in order to more effectively suppress foreign matter generation due to the movement of the chain 131. The upper end of the corrugated pipe 140 is fixed to the lower surface of the first box member 112. The corrugated pipe 140 is expanded and contracted corresponding to the change of the length of the chain 131 to further improve the hygiene of the chain 131.

As described above, the hoist device for food according to the preferred embodiment of the present invention is configured such that the main driving parts such as the motor, the chain, and the electric / electronic controller part are both exposed to the outside by the structure wrapped by the box member made of stainless steel And each box member is sealed to be waterproof.

The hoist device for foodstuffs with this structure prevents rusting and prevents various foreign substances from dropping to the workpiece during operation. Therefore, it is applied to the food production line and also to the clean room, etc., Can be performed. Further, after the work is completed, the water can be sprayed directly onto the hoist device, thereby making it possible to freely perform the cleaning work and has a remarkable effect of excellent rust prevention performance.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not to be limited to the details thereof and that various changes and modifications will be apparent to those skilled in the art. And various modifications and variations are possible within the scope of the appended claims.
