  However, according to the former mesh belt in which the mesh is relatively coarsely formed, the belt by the sprocket is engaged by engaging the teeth of the sprocket with this mesh utilizing the mesh at both ends of the mesh belt in the width direction. Because the mesh is rough on the mounting surface on which the article is placed, the article may become unstable or bitten into the mesh when used for transporting small articles. It is likely to be placed in place and to fall through the mesh.

  On the other hand, according to the latter mesh belt in which mesh is clogged, small articles can be stably placed and transported on the mounting surface without dropping, etc. If it is not possible to engage, and if it is possible to feed by sprockets, attach a chain over the entire length of this mesh belt and engage the teeth of the sprocket with this chain The mesh belt needs to be fed, and the cost is increased.

  The present invention has been made in view of such problems, and the object of the present invention is to provide a mounting surface on which a small article can be stably mounted and transported, and a chain It is an object of the present invention to provide an article conveying mesh belt capable of being fed by a sprocket without providing an etc.

  In order to achieve the above object, according to the mesh belt for article transport of the present invention, as described in claim 1, a large number of spiral wire rods are provided side by side at regular intervals in the transport direction, and adjacent spiral wire rods A flexible mesh belt body having a constant width is formed by inserting a force aggregate between overlapping bent portions and connecting spiral wires to each other, and a central portion excluding both end portions in the width direction of the mesh belt body is formed. The middle spiral wire is woven between the adjacent spiral wires at the same spiral pitch as the spiral wire, so that the middle spiral wire does not exist on the article mounting surface in which the center portion in the width direction is clogged. The mesh is rough at both ends of the gear, and the mesh is formed with a drive end that can be engaged with the teeth of the sprocket.

  In the mesh belt for article conveyance configured in this manner, the mesh belt main body according to the second aspect of the present invention is a large number of spiral wire rods, either rightward spiral wire or leftward spiral wire, in the conveyance direction It is formed by inserting the force aggregate between the bent portions of the spiral wires adjacent to each other in the transport direction and connecting the spiral wires, while arranging them side by side at regular intervals. The middle spiral wire made by spiral winding at the same spiral pitch as the spiral wire and in the direction different from this spiral wire in the center of the mesh belt main body except for both end portions in the width direction is spiraled in the intermediate spiral wire. The above-mentioned elastic aggregate is penetrated to the central part of the bent space, and each above-mentioned spa which adjoins the conveyance direction By centering the spiral wire at half pitch with respect to these spiral wires, the central portion in the width direction is formed on the article mounting surface in which the mesh is clogged, while both ends in the width direction where the intermediate spiral wire does not exist It is characterized in that the portion is formed at the drive end portion which is rough meshed and engageable with the teeth of the sprocket.

  The invention according to claim 3 is that the both ends of the spiral wire forming the mesh belt main body are integrally connected by welding to both ends of the force aggregate where the bent portions of the spiral wire are engaged. It features.

  According to the invention of claim 1, in the mesh belt main body comprising a large number of spiral wires formed by bending a metal wire having a predetermined length in a spiral and a force aggregate connecting adjacent spiral wires, Since the intermediate spiral wire made by spiral winding with the same spiral pitch as this spiral wire is interposed between the adjacent spiral wires in the central portion excluding both ends in the width direction of the mesh belt body, both ends are excluded. The central portion in the width direction can be formed on the mesh-packed article mounting surface, and therefore, even a relatively small article is stable without causing a situation such as cutting into or dropping through the mesh. It can be transported in the mounted state.

  Furthermore, according to the present invention, since the intermediate spiral wire is not disposed at both ends in the width direction of the mesh belt main body, the spiral wire constituting the mesh belt main body and the force aggregate are used. It can be formed at both ends of the belt having a relatively large mesh, and can be used as a drive end that can engage the teeth of the sprocket with this mesh to allow the mesh belt to travel reliably and smoothly.

  Further, according to the invention as set forth in claim 2, the mesh belt main body is provided with a large number of spiral wire members, which are either rightward spiral wires or leftward spiral wires, arranged in parallel at regular intervals in the transport direction. Since the force aggregate is inserted between the bent portions of the spiral wires adjacent to each other in the belt width direction so as to connect the spiral wires to each other, each force aggregate The bent portions overlapping each other in the belt width direction of the spiral wires adjacent to each other in the transport direction are engaged at regular intervals in the length direction (belt width direction), and the spiral wires are engaged between the adjacent bent portions It is possible to provide a force aggregate portion of a certain length which is one side of the mesh, and therefore, at one end of the mesh belt, the mesh teeth are engaged with the teeth of the sprocket at one end of the mesh belt. While engaged in a state without causing such distortion mesh belt, it can travel accurately and smoothly stably at any time.

  Further, an intermediate spiral is formed in the same spiral pitch as that of the spiral wire forming the mesh belt main body and in a direction different from that of the spiral wire at a central portion excluding both end portions in the width direction of the mesh belt main body. The force aggregate is inserted through the center of the spirally bent space of the intermediate spiral wire, and the wire is shifted by a half pitch relative to the spiral wires between the spiral wires adjacent in the transport direction. Because it is woven, it is possible to easily and accurately form an article mounting surface in which the mesh is clogged at the central portion in the width direction of the mesh belt.

  According to the third aspect of the present invention, both ends of the spiral wire forming the mesh belt main body are integrally connected to both ends of the force aggregate engaging the bent portions of the spiral wire by welding. Therefore, it is possible to hold the distance between both ends of the rigid aggregate adjacent in the transport direction firmly constant, and engage the teeth in the mesh of the both ends to feed the belt. In spite of the rotation, it is possible to drive reliably and smoothly without increasing the distance between the ends of the adjacent force aggregate or distorting the belt.

  A concrete embodiment of the present invention will be described with reference to the drawings. In FIGS. 1 to 4, the mesh belt for transporting articles has a large number of spiral wire members 1 bent in a spiral shape over the entire length, the length of the belt A mesh belt main body A having a constant width is formed by arranging the spiral wires 1 and 1 adjacent to each other at regular intervals in the length direction, that is, the conveyance direction of the articles and connecting the adjacent spiral wires 1 and 1 with a force aggregate 2. At the central portion of the belt main body A excluding the both ends, the intermediate spiral wire 3 shorter in length than the spiral wire 1 is woven between the adjacent spiral wires 1 to make the central portion in the width direction the entire length. The mesh 4 is rough on both ends in the width direction where the intermediate spiral wire 3 does not exist on the article mounting surface A1 in which the mesh is clogged so that the teeth b of the sprocket B can be engaged with the mesh 4. In which by comprising forming a use end A2, A2.

  More specifically, the spiral wire 1 constituting the mesh belt main body A together with the force aggregate 2 has one winding of a metal wire having a constant diameter and a constant length for every constant length. While forming the spiral portion 11, the spiral portion 11 is bent and formed in a spiral shape continuous at a constant pitch over the entire length. When this spiral wire 1 is viewed from the side, as shown in FIG. 3, the spiral wire 11 in one winding shape has a belt length with the center of the metal wire before being bent in a spiral shape as a central axis x. The front and back portions oriented in the direction are formed into the front and back bent portions 11a and 11b bent back in an arc shape, and the upper and lower facing ends of the front and back bent portions 11a and 11b are continued by the horizontal wire portions 11c and 11d. It is formed in an oval or track shape.

  The winding direction of the spiral wire 1 may be either right-handed or left-handed, but in this embodiment, as shown in the figure, the left-handed spiral wire 1 is adopted, and this left-handed one is used. A large number of winding spiral wires 1 are arranged at regular intervals in the front-rear direction (belt length direction), which is the conveyance direction, and the same length as the spiral wire 1 is provided between the spiral wires 1 adjacent to each other. The mesh belt main body A is configured by sequentially connecting with the force aggregate 2 made of a straight metal wire having.

In order to connect the spiral wires 1 adjacent to each other by the force aggregate 2, the rear bent portion 11 b of each spiral portion 11 of the spiral wire 1 on the front side preceding in the transport direction and the rear side following on in the transport direction The front bent portions 11a in the spiral portions 11 of the spiral wire 1 are superimposed on each other in the width direction of the belt in a butt-like manner, and the force aggregate 2 is inserted into the space surrounded by the inner surfaces of the front and back bent portions 11a and 11b. And the front and rear bent portions 11a of the spiral wire rods 1, 1 adjacent to each other
, 11 b are engaged by being engaged with the force aggregate 2.

  As described above, with the spiral wires 1, 1 having the same winding direction as the same direction, the front and rear bent portions 11a, 11b of the adjacent spiral wires 1, 1 are overlapped with each other in the belt width direction to make a force aggregate Unlike the mesh belt formed by alternately arranging the right-turned spiral wire and the left-turned spiral wire and connecting them with the power aggregate, the force aggregate 2 is inserted and connected. The force aggregate 2a of a certain length not engaged with the spiral wire is exposed between the front and rear bent portions 11a and 11b and the front and back bent portions 11a and 11b adjacent to each other in the belt width direction. The force aggregate 2a and the upper and lower wire portions 11c and 11d of the spiral portion 11 can form a relatively large mesh 4 having a planar triangular shape. Further, both ends of all the spiral wire rods 1 are integrally connected and fixed by welding to both end portions of the force aggregate 2 in which the bent portions 11a and 11b of the respective spiral wire rods 1 are engaged.

  In the mesh belt main body A formed in this manner, the length is shorter than the spiral wire 1 between the adjacent spiral wires 1 in the central portion excluding the both ends of the mesh belt A, and the spiral The middle portion of the mesh belt main body A in the width direction has a full length by incorporating the intermediate spiral wire 3 which is spirally wound at the same pitch as the spiral wire 1 in the rightward direction different from the spiral winding direction. Over the entire area, the mesh 4 is formed on an article mounting surface A1 which is clogged so as to be extremely fine.

  The intermediate spiral wire 3 has the same shape as the spiral wire 1 constituting the mesh belt main body A except that the length and the spiral winding direction are different. That is, while forming a spiral portion 31 having the same size and the same shape as the spiral portion 11 of the spiral wire 1 for every predetermined length, the spiral wire rod extends over the entire length of the metal wire having a constant diameter and length. It is bent and formed in a spiral shape continuous at the same pitch as the spiral portion 11 of FIG. Therefore, when this spiral wire 1 is viewed from the side end of the belt, as in the case of the spiral wire 1, as shown in FIG. The front and back portions oriented in the longitudinal direction of the belt are formed into the front and rear bent portions 31a and 31b which are bent back and forth in a circular arc shape, and the upper and lower facing ends of the front and back bent portions 31a and 31b are horizontal A continuous oval or track shape is formed by the wire portions 31c and 31d.

  In the intermediate spiral wire 3 thus formed, the force aggregate 2 is inserted through the central portion of the spiral portion 31 and the spiral wire 1 between the spiral wires 1 adjacent to each other in the back and forth (conveying direction) By weaving in a state of being shifted by half a pitch with respect to 1, the upper bent portion 31c of the spiral portion 31 of the spiral wire rod 1 adjacent to the front and rear in the spiral portion 11 of the spiral wire rod 1 of the front side , 11d in the middle part in the longitudinal direction, and the rear bent part 31b is connected to the middle part in the longitudinal direction of the upper and lower wire parts 11c, 11d in the spiral part 11 of the spiral part 1 on the rear side. The intermediate spiral wires 3, 3 disposed in a state of being joined between the side surfaces and adjacent to each other in the back and forth direction overlap the front half portion and the rear half portion of the spiral portion 31 in the width direction of the belt. The center in the width direction of the mesh belt body A is formed by the upper wire portions 11c and 31c formed in the horizontal shape of the spiral portions 11 and 31 of all the spiral wire 1 and the intermediate spiral wire 3 incorporated in the The portion is formed on the smooth article mounting surface A1.

  On the other hand, the teeth b of the sprocket B are formed by combining the both ends of the spiral wire 1 and the both ends of the force aggregate 2 without providing the intermediate spiral wire 3 at both ends in the width direction of the mesh belt body A. Drive ends A2, A2 are formed having an open mesh 4 which can be inserted and engaged. The width of the driving end portions A2 and A2 is not particularly limited, as long as several coarse meshes 4 are provided in parallel in the width direction.

  The mesh belt for transporting articles configured in this manner has the sprocket 4 as the mesh 4 at the drive ends A2 and A2 between the drive sprocket B and the driven sprocket (not shown), as shown in FIG. 6 and FIG. The tooth b is engaged in a meshing state, and is endlessly stretched, and travels by the rotation of the drive sprocket B. At this time, the teeth b of the drive sprocket B are engaged with the force aggregate portion 2a facing in the belt width direction which forms one side of the triangular mesh 4 of the drive ends A2 and A2 of the mesh belt. Both ends of the mesh belt are accurately pushed in the transport direction with uniform force, and both ends of the spiral wire 1 forming the mesh belt main body A are integrally connected to both ends of the force aggregate 2 by welding. Coupled with this, the mesh belt can be smoothly run in a stable state.

  In addition, since the central portion in the width direction of the mesh belt is formed on the smooth article mounting surface A1 as described above by weaving the intermediate spiral wire 3 as described above, it is a small-sized article. However, the sheet can be conveyed in a stable posture without being inclined during the conveyance.

  In the above embodiment, a spiral wire wound left is used as the spiral wire 1 forming the mesh belt main body A together with the force aggregate 2, but a spiral wire wound right may be used. . In this case, it is a matter of course that a left-handed spiral wire is used as the intermediate spiral wire. Also, by combining left-handed spiral wire, right-handed spiral wire and force aggregate, both ends in the width direction are formed on the coarse driving end of the mesh on the dense article placement surface of the mesh in the center in the width direction. You may leave it.
