Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerial orbit installed on the ceiling of a building so that a large meat block such as pork or beef can be transported manually (by hand) or automatically in a meat factory or a meat storage. The present invention relates to a meat suspending tool for suspending it freely.

[0002]

[Technical background] A large block of pork or beef stored in a meat factory or a meat storage has a weight of 70-
There is about 200 kg, and in the case of pork, 2 pieces are suspended in 1 suspension tool, and in the case of beef, 1 suspension system is used. Such a suspension tool is installed on the aerial track installed on the ceiling of the building. Hundreds to thousands are suspended and used in a normal-scale meat factory or meat storage. In addition, this meat suspension device is supposed to be sterilized and disinfected each time it is used.

[0003]

2. Description of the Related Art Conventionally, since the suspending tool has been formed by using a metal material having relatively high strength, the suspending tool itself becomes considerably heavy (about 5 kg), which will be described later. As described above, not only is the handling of the work to remove or install from the aerial orbital heavy and the handling is poor, but also the aerial orbital installed on the ceiling of the building and the ceiling itself of the building supporting the aerial orbital are large. There was a problem that became.

Also, the suspenders for meat are sterilized after each use.
Since it is sterilized, the suspension must have excellent chemical resistance and corrosion resistance.For that reason, it is necessary to use a metal material having relatively high strength in the conventional suspension. However, there was a problem that the manufacturing cost became high.

Further, in the conventional suspension, not only must the lubricating oil be frequently applied to the pulley portion which is movably suspended in the aerial track, but also the pulley portion must be applied during the sterilization / disinfection treatment. It must be removed from the orbit one by one to prevent the lubricant from being washed out. Therefore, the maintenance is very troublesome, and the lubricating oil and rust generated on the suspending tool may fall on the meat to deteriorate the quality.

In addition, in the conventional suspension, when the sheaves move on the aerial orbit, the sheaves collide with each other, which causes intense noise, and the rotating portions of the sheaves are crushed or damaged and cannot rotate. There was a problem that it was easy to become.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of such conventional problems, and is excellent in chemical resistance and corrosion resistance, and can be reduced in weight and cost. The provision of a meat suspender that allows the pulleys that are movably suspended in the aerial track to be oil-free and that prevents the pulleys from colliding with each other when moving on the aerial track Is.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In the figure, A shows a meat suspending tool according to the present invention, and B shows an aerial track installed on the ceiling of a building for suspending and supporting the meat suspending tool A so as to be movable.

The meat suspending tool A comprises a trolley member 1 suspended on an aerial track B and two upper and lower suspensions which are suspended and supported so as to be rotatable 180 ° in the horizontal direction with respect to the trolley member 1. It is composed of lowering members 2 and 3. The upper suspension member 3 directly suspended from the trolley member 1 in the drawing is a suspension member that also serves as a connecting tool and is provided with a hook 31 for suspending beef, and is formed on the trolley member 1. The lower suspension member 2 can be directly hooked on the hooked portion 11 for use, and is not always necessary.

The trolley member 1 has an aerial track B on its upper part.
It comprises a pulley 12 which is rotatably mounted on the upper part, and a hook 11 for hooking the upper hanging member 3 or the lower hanging member 2 is formed in the same body at the lower part.

At this time, the outer size (L ₁ ) of the pulley supporting portion 13 of the trolley member 1 is formed larger than the outer diameter (L ₂ ) of the pulley 12 (L ₁ > L ₂ ). Also,
A rotation support shaft 14 for rotatably supporting the pulley 12.
Is a pulley supporting portion 1 of the trolley member 1 as in the illustrated embodiment.
The nut 15 may be formed so as to project from the same body as 3, or may be formed as a separate body and attached, and a nut 15 is screwed to the tip portion so that the pulley 12 does not fall off.

A bearing 16 formed of a fiber reinforced plastic material or a synthetic resin material is interposed between the pulley 12 and the outer periphery of the rotary support shaft 14 so that the pulley 12 can rotate smoothly without oil. Install it.

The lower suspension member 2 is formed in a substantially A shape on the front surface, and the hook portion 1 of the trolley member 1 is provided on the upper portion thereof.
1 or an engaging hole 21 for hooking on the hook 31 of the upper suspension member 3 is formed, and hooks 22 for hooking the meat C on both sides of the lower portion are formed in the same body,
An appropriate identification mark 24 is formed and attached to the central recess 23.

The identification mark 24 is for managing the meat C suspended from the meat suspender A, specifically, for identifying the meat producer or processor, distinguishing the weight and quality of the meat, and storing / storing the meat. It is for managing shipping, etc., and is the same when molding the lower suspension member 2 in the recess 23 of the lower suspension member 2 by using numbers, alphabets, or appropriate symbols, pictorial patterns, or colors. It is formed and applied integrally, or it is formed and applied by filling or pasting after forming the lower suspension member 2. The identification mark 24 is not limited to being formed in the recess 23 of the lower suspension member 2, but may be formed and attached to the upper suspension member 3.

Then, the trolley member 1, the lower hanging member 2 and the upper hanging member 3 are formed by using a fiber reinforced plastic material (FRP material or FRTP material).

Specifically, glass fiber or carbon fiber is used as a reinforcing material, and a thermosetting resin such as unsaturated polyester resin or epoxy resin is used as a matrix (F).
(RP material) or a thermoplastic resin such as nylon or polypropylene is used as a matrix (FRTP material)
Things. In this case, there is no particular restriction on the molding method.For example, short fibers made of glass fibers or carbon fibers are impregnated with an uncured thermosetting resin, and this sheet is heated and pressed with a mold. It may be molded by an SMC method (sheet molding compoud method) for molding by molding, or when an FRTP material is used, it may be molded by an injection molding method.

The pulley 12 may be formed of a fiber reinforced plastic material (FRP material or FRTP material), but a synthetic resin material such as polyacetal resin having excellent rigidity and abrasion resistance and abrasion resistance is used. You may form.

Here, the fiber reinforced plastic material (FRP
The strength test of the lower suspension member 2 and the upper suspension member 3 according to the present example formed by using the material was performed.

The maximum stress occurs at the X part in the figure, and the stress at that time is 1.
It was ² Kg / mm ² . Further, the hook 31 of the upper suspension member 3 was suspended with 200 kg of meat C, which is usually rare. Then, the maximum stress was generated in the Y portion in the figure, and the stress at that time was 1.8 Kg / mm ² . Since the fracture stress of the fiber reinforced plastic material (FRP material) used in this example is 10 kg / mm ² or more, even with the above-mentioned generated stress, expect a safety factor of 8 times or more in the case of the lower suspension member 2. In addition, in the case of the upper suspension member 3, a safety factor of 5 times or more can be expected. From this test, it was confirmed that the lower suspending member 2 and the upper suspending member 3 according to the present example can be sufficiently used even in consideration of fatigue, aging, and the like.

EFFECTS OF THE INVENTION Since the meat suspension device of the present invention is constructed in this manner, it has better chemical resistance and corrosion resistance as compared with those formed of conventional metal materials without any special surface treatment. At the same time as being excellent, it is possible to significantly reduce the weight and reduce the cost. By the way, the product of the present example could be formed with a weight half that of the conventional product (about 2.5 kg). Therefore, not only is it easy to carry and carry, but it is also possible to significantly reduce the burden on the aerial track installed on the ceiling of the building and on the ceiling itself of the building supporting the aerial track, which in turn results in the aerial track and It is possible to simplify the structure of the building and reduce the facility cost.

Moreover, since a bearing made of a fiber reinforced plastic material or a synthetic resin material is interposed between the pulley and the outer periphery of the rotary support shaft projecting from the pulley supporting portion of the trolley member, the bearing can be freely moved in the aerial orbit. It is possible to expect smooth rotation of the pulley without using special lubricating oil for the suspended pulley, and it is possible to use it without lubrication. As a result, during the sterilization / disinfection process, it is possible to perform the sterilization / disinfection process as it is without removing it from the orbit in the air. Therefore, the maintenance becomes very easy, and there is no possibility that the lubricating oil or the rust generated on the suspending tool will fall on the meat as in the conventional case.

Further, since the outer shape of the pulley supporting portion of the trolley member is formed to be larger than the outer diameter of the pulley, FIG.
As shown in Fig. 4, even if the pulley supporting parts contact each other when moving on the aerial orbit, the pulleys do not collide with each other, so that the rotating part of the pulley is crushed or damaged and cannot rotate. It is possible to use it with peace of mind for a long period of time, and in combination with the fact that the trolley member is made of FRP material, it is possible to achieve a significant reduction in noise.

Further, since the hanging member is provided with an identification mark for controlling the suspended meat, the meat producer and the processor are identified, the weight and quality of the meat are classified, and the meat is stored. -It becomes possible to easily manage shipping and the like.
