Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for transporting raw tea leaves in a green tea production process and a small raw material for processing steps such as steaming, heating, and drying of fry and small fish (eg, shirasu, cremenjako, boiled, etc.). Fish supply / transport equipment, transport equipment for each processing step such as peeling, cutting, chopping, steaming, heating, frying and drying of raw vegetables and root vegetables, washing / draining of seaweeds / seaweeds, etc.
Regarding the structure of the transport belt used for the transport device for various processing processes such as drying, it is used especially for the device that transports the processing raw materials and products while moving up or down to the next process device with a steep step. The present invention relates to a structure of a transport belt for transporting and supplying a fixed amount at a time without sliding down a transported object.

[0002]

2. Description of the Related Art FIG. 1A is a schematic side view showing an example of an apparatus for supplying and transporting raw fish to a small fish heating / drying processing apparatus which has been conventionally used. The dispersed raw material fish 1 is pumped up by a bucket 2 made of a stainless steel plate or a steel plate and supplied onto a mesh belt 4 of an upper heating / drying device 3.

The bucket 2 is rotatably mounted on a driving chain via a bar. When the driving chain changes its direction at the highest position, the opening of the bucket 2 faces downward, and the small fish in the bucket is turned. Is supplied on the mesh belt 4. Instead of the buckets installed in the drive chain, mesh belts are used which are continuously transported and supplied by attaching various cross rails to a wire mesh mesh belt woven or knitted with a metal wire such as stainless steel. The horizontal rail is a rod-shaped or band-shaped body attached to the transport belt at a right angle to the traveling direction and at an appropriate interval in the traveling direction over substantially the entire width. Refers to a device that has the function of preventing

When attaching various cross rails to a wire mesh mesh belt, a metal plate made of the same material as the wire mesh mesh belt or a rigid woven or knitted rigid plate-shaped piece has been fixed by welding.

[0005] However, when the transport belt made of the above-mentioned metal wire or the like is always used in contact with seawater or the like in which various electrolytes mainly composed of sodium chloride are dissolved, it is no matter how stainless steel is used. In some cases, corrosion resistance and food hygiene are not preferred.

Therefore, polyethylene terephthalate (P
ET), that is, a so-called mesh belt coarsely woven using synthetic resin fibers such as polyester resin fiber monofilaments is employed, and problems of corrosion resistance and food hygiene have been avoided.

[0007] The transport belt of the present invention comprises
It is not limited to coarse mesh belts composed of synthetic resin monofilaments or multifilaments, but also applicable to transport belts with a relatively dense structure woven with fiber yarns. is there.

[0008] Since a mesh belt formed of a monofilament made of PET resin or the like is widely used, a mesh belt will be representatively described below.

In the mesh belt woven from the synthetic resin fiber monofilament, the running direction (length) of the mesh belt is set so that the raw fish can be transported and supplied to the next process device having a steep step without slipping. At right angles to the vertical direction, horizontal rails for preventing products and raw materials from slipping are installed at appropriate intervals.

FIG. 1 (B) is a schematic view of the use state of the synthetic resin mesh belt 5 to which the cross rail 6 is attached. The conveyed object, for example, a small fish, is drained by the mesh belt 5 and is blocked by the cross rail 6, and is conveyed in the direction of the arrow 7 without sliding down below it. Conventionally, the cross rail 6 has been fixed and used on a mesh belt in a typical method and form shown in FIGS. 1 (C) to 2 (H).

FIG. 1C shows an example in which the mesh belt body 8 is bent in an inverted T-shape at desired intervals in the running direction to form a horizontal rail 9 having a desired height H. It is. FIG. 1D is a schematic side view thereof, and FIG. 1E is a schematic front view thereof. When the horizontal rail 9 is formed on the mesh belt main body 8, the horizontal rail 9 is sewn with a wire of the same material as the wire constituting the mesh belt main body 8, or is sewn with a sewing machine or the like. Stitching and suturing with a suture 11 are performed at appropriate portions so as to form the upper portion 9a of the plate 9 in a plate shape.

As shown in FIG. 2A, two mesh sheets 12 are stacked on the mesh belt body 8 and
It is also publicly practiced to form a rigid mesh piece 14 for three and sew it with a suture thread 15 as shown in FIG. In some cases, the upper and lower portions of the suture 15 are covered with a synthetic resin adhesive (see FIG. 2C).

FIG. 2C shows a state in which the rigid mesh piece 14 is sewn to the mesh belt main body 8 as shown in FIG. The separately attached resin is melted by high frequency welding or ultrasonic welding to form the reinforcing layer 16 and the suture 15
Is confined in the resin.

Further, as shown in FIGS. 2 (D) to 2 (H),
An oblong bar 17 (see FIGS. 2D and 2E) made of a dielectric resin such as a polyvinyl chloride resin or a polyurethane resin, and a T-bar 18 (see FIG. 2F)
(G), and L-shaped bar 19 (see (H) in FIG. 2) are used by high-frequency welding.

[0015] Japanese Utility Model Registration No. 2554909 proposes that a conveyor belt made of a synthetic resin made of synthetic resin is improved in bending resistance by improving the structure of a skirt thereof.

[0016]

FIG. 1 (C)-(E)
In the case of, the superimposed meshes 8 ₁ and 8 ₂ forming the horizontal rail 9 are driven by the driving tension of the mesh belt with respect to the suture 10 (or spelling thread) when the horizontal rail 9 is sewn to the mesh belt body. A force separating the mesh belt in the traveling direction forward side (front side) and the traveling direction backward side (rear side) continuously acts, and furthermore, the continuous bending action of the cross rail 9 in the front-rear direction allows the mesh belt to perform the above-described sewing. In some cases, the suture thread 10 was fatigued and cut shortly after the start of use of the mesh belt, and the horizontal bar 9 was opened, thereby losing the function of the horizontal bar 9 at an early stage.

If the opening of the cross rail 9 is not uniformly generated over the entire width of the mesh belt, a difference occurs in the length of the ear a on one side and the ear b on the other side of the mesh belt 8 in FIG. In some cases, the mesh belt may not be able to be used at an early stage due to misalignment, mechanical failure, breakage of the mesh belt, or the like such that the mesh belt travels sideways and is wound around a frame or a mechanical part of the transfer device.

In the case of FIGS. 2A and 2B, the suture 1
In some cases, the horizontal rail 13 or the mesh belt body 8 could not be used up to the expected service life due to cutting or the like caused by wear of No. 5. In the case of FIG. 2C, although the improvement is made as compared to the case of FIG.
Was exposed and cut off, and the horizontal rail 13 was detached from the mesh belt main body 8 and could not be used up to the expected life.

In both FIGS. 2B and 2C, when sewing the rigid mesh piece 14 and the mesh belt 8, it is very difficult to sew a suture thread 15 around the base S of the upright piece 14a with a sewing machine or the like. However, it was extremely uneconomical to install a large number of crosspieces with great effort.

In the case of (D) to (H) of FIG.
For heat generation during high-frequency welding of 18, 19,
The mesh belt is pretreated (heat set) at a temperature sufficiently higher than the temperature of heat generated during high-frequency welding to deal with the problem. However, pre-treating the mesh belt at a temperature higher than the heat-resistant temperature of the material of the welded crosspiece is extremely uneconomical because it involves an extra process step.

In these cases, the heat resistance limit temperature of the resin forming the horizontal rail is low, and it is difficult to apply the device to a device affected by heat, and in some cases, the application is impossible.

When used in a low-temperature atmosphere, the resin hardens, and the mesh belt contacts and rotates with the rollers of the conveying device at the portion where the cross rails 17, 18, and 19 are attached. Without being able to follow the bending action,
In some cases, 18 and 19 were damaged at the bonding portion with the mesh belt and dropped off.

The most difficult thing is that the dielectric resin is not physically and chemically bonded to the mesh belt main body, so that the mesh belt main body comes into contact with the rollers of the transfer device to rotate. For repeated bending action of time,
Since it could not be followed, the joints were broken due to fatigue, and the crosspieces 17, 18, and 19 could fall off from the mesh belt main body in a short-term use.

The technique described in Japanese Utility Model Registration No. 2554909 basically involves adhesively connecting a horizontal rail to a mesh belt main body. It is difficult to expect a strong bond, and improvement in durability is unlikely.

The foregoing has mainly described the prior art and the technical problems of the mesh belt with cross bars in the process of processing marine products such as small fish, but is not limited to this process and other similar processes and similar devices This is also a matter that can be mentioned in the case of a transfer belt with a horizontal rail used in a vehicle.

That is, a raw tea leaf conveying device in a green tea production process,
Transport equipment for each processing step such as peeling, cutting, chopping, steaming, heating, frying and drying of raw vegetables and root vegetables, and transport equipment for various processing steps such as washing, draining and drying of seaweed and laver It is also a matter which can be referred to a transfer belt with a horizontal rail used for the above-mentioned.

The present invention has been proposed in order to prevent a trouble of a horizontal rail coming off from a mesh belt main body in the prior art and to eliminate unnecessary uneconomical heat treatment of a mesh belt. Its purpose is to fix the horizontal rail firmly to the mesh belt body by simple installation work without interposition of sewing or adhesion and welding with synthetic resin, and to significantly improve the durability against severe bending action and friction. The purpose of the present invention is to provide a conveyer belt that can be obtained.

[0028]

In order to achieve the above-mentioned object, the present invention comprises a mesh belt body knitted and woven with fiber yarns, and a horizontal beam standing upright on the surface of the mesh belt body at appropriate intervals. In the conveying belt, from the back side to the front side of the mesh belt main body, a spiral wire made of a synthetic resin monofilament yarn having a spiral loop that is pushed across a fiber thread extending in the running direction of the mesh belt main body, A horizontal rail is formed by a stuffer wire inserted into the spiral loop on the surface side of the mesh belt main body for locking and fixing the spiral wire to the mesh belt main body.

Further, according to the present invention, the spiral wire is combined in two or more stages on the surface side of the mesh belt main body and a joint core wire is inserted into a common hole formed by meshing spiral loops with each other. It is what constituted.

Further, the present invention relates to a transport belt having a mesh belt body knitted and woven with fiber yarns and a horizontal rail standing upright on the surface of the mesh belt body at an appropriate interval. From the surface side to the surface side, a base made of a synthetic resin monofilament yarn spiral wire having a spiral loop that is pushed across a fiber thread extending in the running direction of the mesh belt body, and a loop that meshes with the spiral loop of the base. A band-shaped member provided on the base end side, and the base is engaged and fixed to the mesh belt body by being inserted into a common hole of a mutual loop of the base and the band-shaped member, and joining the band-shaped member to the base The crosspiece is composed of the core wire.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 4A to 5B
FIG. 4 is a conceptual diagram showing an example of an embodiment of the present invention and showing an operation procedure for attaching a horizontal rail 9 to a mesh belt main body 8.

In FIGS. 4A and 4B, a group of latitudes 8a and a group of meridians 8b of the mesh belt body 8 are entangled and organized to form a space 8.
c is configured. Among these parallels group, there is a grating group 8d meridians disposed between a pair of parallel 8a _1, 8a ₂ selected. A spiral wire 20 (hereinafter, referred to as a spiral wire) for hooking the cross rail shown in FIG. 4C is inserted into the space groups 8e, 8e formed between the pair of wefts and the warp.

In FIG. 4D, the tip loop 20a of the spiral wire 20 is pushed into the space 8e. At this time,
Adjacent loops 20a, 20a straddle the meridian 8bx, and the rear end loop 20b of the spiral wire is
bx.

Then, FIG. 5A (FIG.
(D) is a view in which the loop top 20a is pushed in, that is, as viewed from the back surface 8S), the loop bottom 20b in FIG. 4D is locked to the meridian, and the loop top 20a is locked.
Project from the back side 8B of the mesh belt to the front side 8S (see FIG. 5B).

Next, FIG. 5C shows a state in which the stuffer wire 23 is inserted into the space 22 of the loop 21 between the top 20a of the spiral wire 20 and the surface side 8S of the mesh belt in FIG. 5B. FIG. 3 is a diagram showing a spiral wire 20 fixed and viewed from the front side. FIG. 6 is a front view of FIG. 5C.

Thus, as shown in FIGS. 5C and 6, the horizontal rail 9 is formed on the mesh belt 8.

With this structure, FIG. 5C and FIG.
The horizontal rail 9 is fixed to the mesh belt 8 very firmly because conventional sewing or bonding / welding with a synthetic resin does not intervene.

Then, as shown in FIG. 7A, even if the mesh belt 8 is rotated while being in contact with the driving roller 24, the reversing roller 25a, the guide roller 25b, etc. under tension, the horizontal rail 9 is meshed. Since it is firmly fixed on the belt 8 with the wire,
Is not easily released or dropped. Since the reversing roller 25a is installed such that the small-diameter rotating roller comes into contact with the belt at the bent portion, a severe bending action acts on the belt.

[Example 1] A spiral wire rod having a spiral wire specification shown in Table 1 was installed on a mesh belt having a mesh belt main body specification shown in Appendix 1 as shown in FIG. Formed.

FIG. 7D is a schematic diagram of this embodiment. Spiral wire 122 on mesh belt body 121

For 6, 148, a polyester monofilament yarn having a diameter of 1.5 mm was used.

The transport belt of this embodiment is suitable for transporting relatively coarse-grained and light substances, and is also effective for preventing contamination of the belt and the horizontal rail, and for cleaning and regeneration.

[Example 3] A spiral wire having a spiral wire specification shown in Table 1 was installed on a mesh belt having a mesh belt main body specification shown in Appendix 1 as shown in FIG. A base 152 for locking 159 was formed.

In this embodiment, a spiral loop 1 is interposed between the meridians (one set of three) 151 of the mesh belt.
I pushed the pieces. Further, a stuffer wire 155 was inserted and fixed in the loop hole 154 of the spiral wire 153 to form a horizontal rail 159.

Also in this embodiment, the width (300 mm) × length (500 mm) of the mesh belt main body 131 in FIG.
In the sample No., the mounting interval P of the horizontal rail 139 was set to 100 mm.

The height of the horizontal rail 159 in FIG. 9A was about 5.0 mm. As the stuffer wire 155, a flat monofilament yarn having a thickness (0.8 mm) × width (2.2 mm) and a rectangular cross section was used.

FIGS. 9B to 9D show the structure of the mesh belt main body 150 (ie, woven fabric). Meridian group 1
51a and the weft line group 151b are entangled with each other to form a woven fabric with fixed openings. This is fixed by resin processing.

The belt of this embodiment can be manufactured by a general machine, and is considered to be advantageous in terms of production cost. In the fixed horizontal rail, the spiral wire composed of monofilaments is firmly fixed on the belt due to the confounding, regardless of the processing resin of the woven fabric, so that the durability is excellent. The belt of this embodiment can be effectively applied to the conveyance of a light substance having a relatively small solid unit (grain).

[Example 4] A spiral wire having a spiral wire specification shown in Table 1 was installed on a mesh belt having a mesh belt body specification shown in Appendix 1 as shown in FIG. Is formed.

In this embodiment, the spiral loop 1 is inserted between the meridians (pairs of two) 162 of the mesh belt.
I pushed the pieces. Further, another spiral wire 164 is engaged with the loop 165 of the base 161 and a joint core wire 167 (polyester monofilament having a diameter of 1.5 mm) is inserted into the common hole 166 thereof.
A stuffer wire 167A (a polyester monofilament yarn having a diameter of 1.5 mm) is inserted and fixed between the second spiral wire 164 and the bottom 164b of another spiral wire 164, and in addition, a stuffer wire 168 (thick (0.8 mm) x width (3.0 mm) flat monofilament yarn with a rectangular cross section)

The structure (plain entanglement) of the mesh belt main body 160 is shown in FIGS. 10B and 10C. The meridian group 162 and the weft group 163 intermingle with each other to form a woven fabric with fixed openings. This is fixed by resin processing.

The belt of this embodiment can be manufactured with general resin processing equipment, and is considered to be advantageous in terms of production cost. In the fixed horizontal rail, the spiral wire composed of monofilaments is firmly fixed on the belt due to the confounding, regardless of the processing resin of the woven fabric, so that the durability is excellent. The belt of this embodiment has a relatively coarse solid unit (grain).
It can be effectively applied to the transport of light substances.

Embodiment 5 Similarly to Embodiment 4, a spiral wire having the spiral wire specification shown in Table 1 is shown in FIG. The base 161 which was installed in the manner described above to lock the crosspiece 169 was formed.

In this embodiment, the spiral loop 1 is inserted between the mesh belt meridians (two pairs) 162, 162.
I pushed the pieces. Further, another spiral wire 164 is engaged with the loop 165 of the base 161, a joining core wire 167 is inserted into the common hole 166, and a stuffer wire between the meridian 162 of the mesh belt and the bottom 164 b of another spiral wire 164. 167A was inserted and fixed, and in addition, a stuffer wire 168 was inserted into the space 164c of another spiral wire 164 to fix the entire cross rail 169. Also in this embodiment, the mounting interval P of the horizontal rail 139 was set to 100 mm in the sample of the width (300 mm) × length (500 mm) of the mesh belt main body 131 in FIG.

In this case, the horizontal rail 169 in FIG.
Had a height of about 18 mm. Six monofilaments made of PEEK having a diameter of 0.9 mm were aligned and used as the joining core wire and the stuffer wire.

In the fixed horizontal rail in this embodiment, the spiral wire composed of monofilaments is firmly fixed on the belt by its entanglement regardless of the processing resin of the fabric.
It will have excellent durability. The belt of this embodiment can be effectively applied to the transport of a light substance having a relatively coarse solid unit (grain), and is particularly effective in a high-temperature atmosphere, and exhibits its merits.

Example 6 Two rows of spiral wires having the spiral wire specifications shown in Table 1 were prepared on a mesh belt having the mesh belt main body specifications shown in Table 1 and attached as shown in FIGS. 10 (D) and 10 (E). To form a base 171 for locking the horizontal rail 179.

In this embodiment, the spiral wires in each row are formed between the mesh belts 172a and 172b (and several pairs by knitting) and 172b and 172.
One spiral loop was pushed between c. Furthermore,
Loops 181a and 181b of crosspiece mesh piece 174
11 (C) and FIG. 11 (D) are combined with the loop 175 of the base 171 to form the common hole 17
6, the joining core wire 177 was inserted, and the mesh belt 170 and the mesh piece 174 for horizontal rails were fixed.

Also in this embodiment, the width (300 mm) × length (500 mm) of the mesh belt main body 131 in FIG.
In the sample No., the mounting interval P of the horizontal rail 139 was set to 100 mm.

To obtain the crosspiece mesh piece 174 in the above.

The knitting structure in this embodiment is as shown in FIG. 12B, and the structure shown in FIG. 12A is generally known as "Marquisette structure" in the Russell knitting and fabric industry. I have.

FIG. 12B shows a case where a weft wire 191 is inserted into a tissue and knitted in order to obtain rigidity in the width direction of the mesh belt. Since knitting is faster than weaving, it is sometimes advantageous in terms of manufacturing cost.

This mesh belt is formed by joining and fixing the meridians, the weft lines and the knitting points of knitting by resin processing after knitting.

In the fixed horizontal rail in this embodiment, the spiral wire composed of monofilaments is firmly fixed on the belt by its entanglement irrespective of the processing resin of the fabric.
It will have excellent durability. The belt of this embodiment can be effectively applied to the transport of a light substance having a relatively coarse solid unit (grain), and is particularly effective in a high-temperature atmosphere, and exhibits its merits.

It is necessary to change the size of the spiral wire in accordance with the mesh size of the mesh belt.
1.5mm, spiral size (short diameter x diameter) is (3 ~
15 mm) × (5 to 20 mm).

The present invention is not limited to the mesh belt, but can be effectively applied to general transport belts woven with fiber yarns. That is, if a part of the thread arranged at right angles to the running direction of the belt is removed and a striated lattice of the thread extending in the running direction of the belt is provided, the loop of the spiral wire is formed so as to straddle the thread. It can be arranged and pushed in, and it becomes possible to provide a cross rail on the transport belt as in the embodiment relating to the mesh belt.

The embodiment of the present invention has the above configuration, and its function will be described below. First, the various crossbars described in Attachment 2 are fixed to the various mesh belt bodies of the mesh belt specifications shown in Attachment 1 and the belts with the crossbars shown in Examples of the present invention and Comparative Examples are described. The durability was compared with the belt running / durability tester shown in FIG. The test results are shown in Table 3 together with the test conditions.

As is evident from the details of the embodiment relating to the specifications of the horizontal rails in Table 2 and the test results in Table 3, the present invention is not limited to a mesh belt woven with synthetic resin monofilaments, but also to a synthetic resin multi-layer. It is possible to provide a cross rail structure applicable to a wide variety of mesh belts up to an ultra-coarse mesh belt woven with filaments and / or monofilaments.

The horizontal rail of the structure has a spiral loop composed of a monofilament made of a synthetic resin having the same material as that of the mesh belt or having higher heat resistance than that of the mesh belt. It is pushed in from the opposite side (hereinafter, referred to as the opposite side) of the beam forming side (hereinafter, referred to as the lateral beam side), and a stuffer wire or the like is inserted into a spiral loop protruding toward the lateral beam side to insert the spiral loop into the lateral beam side. It is fixed so that it can be pulled up strongly.

Accordingly, the spiral loop is only slightly exposed on the opposite side, and the frictional effect on the spiral loop on the opposite side during use of the mesh belt is extremely weak and small. Further, since the spiral loop is formed of a thick synthetic resin monofilament, the spiral loop itself is rich in abrasion resistance, high in strength, and extremely high in durability of the cross rail.

On the other hand, in the structure of the conventional horizontal rail shown in each comparative example, the connection of the horizontal rail to the mesh belt is essentially bonding or sewing, so that the horizontal rail and the mesh belt are connected to each other. Is weak, the connection is weakened by the bending action and frictional action due to repeated contact with the rollers of the transport equipment,
Even when the mesh belt is used for a short period of time, the horizontal rail tends to easily fall off the mesh belt.

Conventionally, as shown in FIG. 13, using a monofilament yarn 201, a horizontal rail 202 (diameter 6 mm) is used.
Is also sewn to the mesh belt 203, but depending on the thickness and the material, the mesh belt body 203 may be sewn.
Since the monofilament yarn 201 of the same material as the synthetic fiber constituting the above is generally rigid, it is extremely difficult to work with a sewing machine, and it is a reality that the work relies exclusively on manual work. Since the horizontal rails 202 are attached innumerably over the entire length of the mesh belt 203, the cost of attaching the horizontal rails becomes enormous.

In each of the above embodiments, the spiral wire was pushed in from the opposite side of the mesh belt so that the bottom of the loop of the spiral wire was engaged with the wire (meridian) extending in the running direction of the mesh belt. As shown, the spiral wire loop 232 is pushed into the mesh belt from the side of the cross between the meridian wires 231, and the fixed core wire 233 and the stuffer wire 234 are inserted on both sides of the mesh belt to fix the spiral loop 232 to the mesh belt. Alternatively, the horizontal rail 239 may be formed.

Further, instead of the crosspiece mesh piece, an appropriate band-shaped member having a loop on one side may be used. In addition, the stuffer wire and the joining core wire are to be prevented from falling off by any means, for example, one end or both ends are folded back and sewn into the structure of the mesh belt main body, or simply bend the end portion Alternatively, they may be bonded and fixed with an adhesive.
