Since cobalt magnets are generally used, the cost is high. Moreover, due to the magnetic force of the magnet i, a large amount of magnetic dust in the air is adsorbed on the surface of the guide rail h, and the guide rail h and the linear body b are rubbed with the rotation of the flexible screw c to promote wear. There was a flaw. Further, if the transported object is made of a magnetic material, the transported object may be magnetized by the magnet i.

搬送可能としたものである。In order to achieve the above-mentioned object, one flexible screw conveying device according to the present invention is rotated by a tubular guide body having a slit portion in the longitudinal direction and having a substantially C-shaped cross section. The flexible screw is freely installed inside, and the guided portion of the transported object is brought into contact with the flexible screw through the slit portion so that it can be transported in the longitudinal direction.

The flexible screw is internally rotatably accommodated in the accommodating portion of the guide body, and the guided portion of the conveyed object is brought into contact with a part of the flexible screw so that the guided body is guided to the conveyed object. It is possible to carry along the longitudinal direction.

Although it can be used, it is preferable to use the flexible screw described in PCT application publication WO91 / 06493.

がよい。The shaft 3 of the screw used in the present invention may be one that does not bend due to the rotation of the screw and has sufficient rigidity to transmit the rotational torque applied from one end of the screw to the other end. A material having both rigidity and flexibility such that it can be easily laid along a conveyance path having a curved portion can be suitably used. For example, the shaft 3 may be entirely made of resin, but good flexibility is imparted. To braid a metal wire on the surface of the resin layer,
A metal wire may be stretched around in the resin layer, or a core material of the metal wire may be provided in the resin layer. However, in order to provide more flexibility and rigidity, it is preferable to use the metal rope 5 having a known structure.

Examples include cobalt and alloys thereof. The structure of the metal rope 5 itself is basically the same as that of a well-known steel rope, that is, several (or several dozen) strands are twisted together and several more strands are twisted on the strand. It has a different structure. Preferably, it is composed of several layers of densely wound coil wire, each layer is a multiple winding of several coils at one pitch, and adjacent layers are sequentially reverse winding. Further, there is no particular limitation on the normal twist, the Lang twist, and the S twist and the Z twist, which are the twisting directions of the ropes.

設けるのが好ましい。When the shaft 3 is the metal rope 5, the filament 4 may be directly wound around the metal rope 5 in a spiral shape, but the filament 4 may be ground by the metal rope 5. For,
Usually, the metal cord 5 contains a lubricant for reducing the friction between the wires, and a coating layer for coating the metal cord 5 in order to prevent the lubricant from evaporating and enhance its holding effect. 6 is preferably provided.

回転が可能である。As the thickness of the coating layer 6 is increased, the good flexibility originally possessed by the metal rope 5 is impaired.
It is preferable that the shaft 3 having a predetermined diameter is as thin as possible.
For example, the diameter of the metal rope 5 is 6.0 mm, but the thickness of the coating layer 6 is usually 0.1 to 2.0 mm, preferably 0.2 to 0.6 mm.
Further, the wall thickness of the coating layer 6 is preferably as uniform as possible in order to increase the concentricity of the screw. Specifically, when the thickness of the coating layer 6 is t, the value of [t (maximum) -t (minimum)] / t is 0.1 or less, preferably 0.05 or less. A screw satisfying this numerical value can rotate at a higher speed.

ると同時に金属索５上に被覆する如く行う。The coating layer 6 may be coated with a resin material by an extrusion coating technique which is usually used. For example, in the case of extrusion coating, similar to the insulation coating of electric wires, while the metal rope 5 is fed out in one direction under constant tension, the resin material is melt-extruded from a die arranged in the axial direction of the metal rope 5 at the same time. It is performed so as to cover the metal rope 5.

金属索５上に鍔を設けるなどが挙げられる。When the coating layer 6 is provided on the metal rope 5, the torque is normally applied from one end of the screw to rotate the entire screw when the coil is conveyed. Therefore, the metal rope 5 and the coating layer 6 are integrally formed due to torque transmission. It is important to rotate. For that purpose, it is preferable to have a structure in which the contact area between the metal rope 5 and the coating layer 6 is large and the coating layer 6 does not slide on the metal rope 5. For example, an appropriate number of protrusions are provided on the metal rope 5, a wire is spirally wound on the metal rope 5,
For example, a brim may be provided on the metal rope 5.

【００２６】一方、上記シャフト３上に螺旋状に設ける

適である。On the other hand, the material of the linear member 4 spirally provided on the shaft 3 may be metal or resin, but it is preferable that at least the surface of the linear member 4 is made of resin for the following reasons. is there.

擦の発生が著しく、線条体４およびガイド体１の内周面
の摩滅が激しい。That is, in the apparatus of the present invention, the screw 2 is inscribed in the guide body 1 and rotated. When the screw rotates, the linear body 4 slides on the inner peripheral surface of the guide body 1, contact friction is significantly generated, and the linear body 4 and the inner peripheral surface of the guide body 1 are worn away significantly.

【００２８】従って、線条体４とガイド体１の損耗をで

条体４の表層８は金属製であるよりも樹脂製である方が
有利である。Therefore, in order to suppress the wear of the linear member 4 and the guide member 1 as much as possible and reduce the maintenance cost, it is advantageous that the surface layer 8 of the linear member 4 is made of resin rather than metal. .

る点で好都合である。本発明では、上記線条体４の座屈
率を 3.0％以下と規定する。A more desirable filament body 4 has a reinforcing core 7 made of a fiber bundle as shown in the figure. The filamentous body 4 having the reinforcing core 7 is advantageous in that it can suppress the elongation of the cord due to the temperature rise due to frictional heat and the tensile load, and as a result can prevent the disorder of the spirally wound cord pitch. is there. In the present invention, the buckling rate of the filament 4 is specified as 3.0% or less.

対する比率で表す。即ち、座屈率εは、ε＝（Ｌ−
Ｌ0 ）／Ｌ0 ×100 （％）の式より求めたものである。The above-mentioned buckling rate is obtained when the surface layer 8 is removed from the linear body 4 in which the reinforcing core 7 is coated with resin, and the reinforcing core 7 is tensioned with a force of 1/1000 of the tensile strength of the reinforcing core 7. Length L
And the difference between the initial length L 0 before removal of the surface layer and the initial length L 0 . That is, the buckling rate ε is ε = (L−
It is obtained from the formula of L 0 ) / L 0 × 100 (%).

【００３１】但し、補強芯７の座屈率が 3.0よりも大き

する線条体４は実用上伸長が皆無に近い。However, if the buckling rate of the reinforcing core 7 is larger than 3.0, the cord tends to expand when tension is applied to the reinforcing core 7 by the amount of contraction of the reinforcing core 7, so the buckling rate is 3.0% or less. It is preferably 0.3% or less, more preferably 0.1% or less, and particularly preferably 0.05% or less, and the linear member 4 having this buckling rate has practically no elongation.

In such a case, the reinforcing core 7 in the polymer cord exists in a state in which it is forcibly stretched beyond the proper length, and if the surface layer is removed during the measurement of the buckling rate, the above-mentioned forced extension occurs. When the contraction length is larger than the length L when the tension is applied, the (L−L 0 ) value becomes negative as a result. If the above buckling rate is too negative, it may lead to cutting of the reinforcing core during use of the screw, but a range of more than -0.5%, especially more than -0.1% is preferable.
