BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor belt that can be easily taken out when an article, such as a cardboard box, is conveyed by a belt in a distribution facility such as a cargo terminal or a distribution center.

[0002]

2. Description of the Related Art Conventionally, a soft synthetic resin belt or a synthetic rubber belt is generally used as a conveyor belt installed in a cargo collection / delivery terminal facility or the like. When a heavy baggage is conveyed by such a belt, the contact surface between the belt and the baggage is increased and slippage is deteriorated, and a great amount of labor is required when the baggage is taken out for separation during conveyance.

In order to improve the slipperiness of a conveyor belt that needs to take out a package during transportation, the surface hardness of the resin is conventionally hardened or a fluorine-based film is attached to the conveyor belt. There is.

[0004]

However, in the case of the former of the above techniques, the hardness of the belt used is 90 degrees (JI
SA) is the limit, and raising the hardness beyond this is not possible in terms of processing as well as physical properties, and in the latter case, the fluorine-based film is expensive. There is a problem that the cost will be high.

The present invention has been researched and developed with the object of solving the above-mentioned problems, and by providing a thermoplastic resin film in which spherical objects are mixed on the surface, the contact surface with the conveyed load is It is an object of the present invention to provide a transport belt which can be reduced in slipperiness and can be easily sorted for cargo to be transported.

[0006]

Means for Solving the Problems As a means for solving the above problems and achieving the object, in the present invention, a thermoplastic synthetic resin in which spherical materials having a diameter of 30 to 150 μ are mixed is present on at least the surface of a base cloth. , A film of at least 150 μ or more is formed, and a part of the spherical object is made of thermoplastic synthetic resin.
Open the conveyor belt, which is characterized by protruding from the surface
Emitted and adopted .

Further, a thermoplastic resin layer or a synthetic rubber layer is layered on at least one side of the base fabric, and the surface has a diameter of 30 to 1
A thermoplastic synthetic resin mixed with 50 μm spherical particles is coated to a thickness of at least 150 μm or more, and
We have developed and adopted a conveyor belt that features that its parts project from the surface of the thermoplastic synthetic resin .

The base fabric used in the present invention can be selected from synthetic fibers such as polyester fibers, nylon fibers, aromatic polyamide fibers, inorganic fibers such as glass fibers, carbon fibers and metal fibers. The base cloth is woven, knitted,
Either non-woven fabric may be used, but woven fabric is preferred. In general,
The fibers used in the base fabric of the present invention are preferably polyester fibers, and more preferably, the filament yarns are less stretchable with respect to tension, and are more preferably formed into plain woven fabric.

As the thermoplastic resin coating the surface of the base cloth, polyurethane resin, polyvinyl chloride resin, urethane-vinyl chloride copolymer resin can be used. The film thickness of such a resin may be 150 μm or more, which has sufficient strength, and is preferably 150 to 300 μm. Further, this coating layer is formed on the base cloth by coating with a resin solution.

As the spherical substance mixed in the thermoplastic resin, those made of glass, hard synthetic resin, or metal are used, but glass is more preferable because it is easily dispersed uniformly.
The size used is in the range of 30 to 150 μ, and is 1: 1 to 1: 5 with respect to the synthetic resin solution (solid content 33%).
Mix at a ratio of (solid content) to ensure uniform mixing.

If the size of the spheres exceeds 150 μ, the ratio with the thermoplastic synthetic resin and the adhered state are adversely affected, which is not suitable. If the size is less than 30 μ, not only the processing becomes difficult, but also the surface of the surface becomes difficult. It is not suitable because the unevenness becomes small and the contact surface with the luggage increases and the slippage worsens. As the synthetic rubber, chloroprene rubber, hypalon rubber, and other synthetic rubbers can be used.

[0012]

[Function] Thermoplastic synthetic resin 2 coated on the surface of base cloth 1
Part of the spheres 3 mixed in is the surface of the thermoplastic synthetic resin.
Since it projects from the surface, the contact surface with the bottom of the luggage is reduced, the slipperiness is improved and the luggage can be easily taken out from the conveyor belt.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A drawing showing an embodiment of the present invention will be described below. (Example 1) Polyester filament 1000d x 1000d 2
The surface of a plain weave fabric 1 of 3 × 23 / inch was coated with 250 g / m ² of a polyurethane resin 2 having the following composition and dried to form a conveyor belt coated with a thickness of 150 μm. Tyforce NY361 (polyurethane resin,
Solid content 33%, manufactured by Dainippon Ink and Chemicals, Inc. 100 parts Glass beads (53μ) 100 parts NE crosslinking agent 5 parts

(Embodiment 2) Polyester filament 1000d × 1000d 2
A soft polyvinyl chloride resin 12 having a thickness of 0.3 mm is layered on the surface of a base cloth 11 of a plain weave of 3 pieces × 23 pieces / inch, and then the synthetic resin layer 12 has the same spherical shape as in Example 1 above. Thing 1
A transport belt was formed by coating the thermoplastic synthetic resin layer 13 in which 4 was mixed to a thickness of 150 μm.

(Embodiment 3) Polyester filaments 1000d × 1000d = 2
Urethane resin 22 is layered on the back surface of the base cloth 21 of a plain weave of 3 pieces × 23 pieces / inch with a thickness of 0.5 mm, and the surface of the base cloth 21 is the same as that in the second embodiment. Was formed.

For comparison, a general soft PVC resin belt and a P having a hardness of 90 degrees (JIS A) used as the belt are used.
The slip properties of the VC resin belt and the belt of the present invention were examined. 1
A 500 g cardboard box with a size of 0 × 10 cm was placed on the inclined surface, and the result of measuring the angle at which it completely dropped to the lower end is as follows.

General soft PVC resin belt 45 to 50 degrees (sliding angle) Hardness 90 degrees (JISA) PVC resin belt 30 degrees (sliding angle) Resin belt of the present invention 12 degrees (sliding angle) As is apparent from these results, The resin belt of the present invention proved to be very slippery.

In the above embodiments (2) and (3), a single layer of the base cloth 11, 21 and the thermoplastic synthetic resin layers 12, 23 has been described, but the present invention is not limited to this. Instead of one, a multilayer such as two layers or three layers may be used.

[0019]

As described above, the conveyor belt of the present invention has at least 150 thermoplastic synthetic resins mixed with spheres having a diameter of 30 to 150 .mu.
It is coated with a thickness of μ or more, and part of the spherical object is thermoplastic.
Since it protrudes from the surface of the synthetic resin, it can be carried on a belt.
Since the contact surface with the bottom of the box containing the transported goods is reduced and the slipperiness is improved, sorting work during transportation does not require a great deal of force and can be easily performed with a small amount of force. it can.

Further, the one in which the thermoplastic resin layer or the synthetic rubber layer is provided on at least one surface of the base fabric has the effect of being strong and excellent in durability and being usable for a long period of time. .
