However, in the conveying device using the above-described puncture needle, the side edge portion of the sheet piece cannot be used for the product and the material waste is generated. Therefore, the work of generating waste and the material waste is generated in the sheet material. There was a problem that fear of mixing material waste into the final product would occur.
Further, in the above-described chain-type transport device 200, when the lower part 212L of the clamp unit is pushed up by the cam 240 to open the clamp unit 212, the lower part 212L of the clamp unit and the cam 240 are worn and the object S to be transported firmly As the clamping force for gripping the clamp increases, the frictional force and the amount of wear between the lower portion 212L of the clamp unit and the cam 240 increase, and the processing load for processing the cam 240 into a special shape is generated. The unit 212, the cam 240, and the like need to be replaced with parts, and the work load increases due to the increased frequency of parts replacement work.

By reducing the load, it is possible to avoid the poor loading of the conveyed product S with respect to the clamp unit 212, and at the same time, the force acting on the chain unit 210 according to the above-described tension increases, so that a thick conveyed object that cannot be bent is conveyed. In addition, there is a problem that it is difficult to extend the life of the chain.
In addition, even with a device that circulates and drives a chain in a plane parallel to the device installation surface by applying the above-mentioned clip chain conveyor, it acts on the chain according to the tension in the same manner as a chain-type transport device using a specially shaped cam.

It is also possible to supply driving force from at least one of the driving sources 130 to drive the conveying mesh chain unit 110 with this one driving sprocket 120 and use the other three driving sprockets 120 as driven sprockets.

Next, the conveyance meshing chain unit 110 according to this embodiment will be described in detail with reference to FIGS.
In addition, since the structures of the meshing chains 111U and 111L described later are common to each other, FIG. 2 is a partially exploded view of the meshing chain 111U and shows the connected state of the components in detail. Detailed description of the detailed configuration is omitted.

As shown in FIG. 1 to FIG. 4, the conveying meshing chain unit 110 according to the present embodiment includes a pair of hook-shaped inner teeth plates 111 </ b> A and 111 </ b> A spaced apart from each other along the chain width direction W and the chain width direction. A plurality of hook-shaped external teeth plates 111B, 111B arranged adjacent to each other outside the pair of hook-shaped internal teeth plates 111A, 111A along W are connected in the longitudinal direction of the chain by a pair of front and rear connection pins 111C, 111C. A pair of meshing chains that are driven by the driving sprocket 120 in a state of being configured to engage with each other to form a chain stiffening portion 110G along the chain stiffening direction DG and that are disengaged from each other and can be branched. 111U, 111L, and when forming the chain stiffening portion 110G, The attachment surfaces 112UP and 112LP of one attachment 112U fixed to one meshing chain 111U of the combined chain 111U and 111L and the other attachment 112L fixed to the other meshing chain 111L are made to face each other. By transporting the transported object S, the chain rigging direction DG extends along the chain rigging direction DG to the opening FW of the two clamping surfaces 112UP and 112LP which are fixed to the chain portion just before meshing among the pair of meshing chains 111U and 111L and open to each other. When the object to be conveyed S is inserted in a straight line to eliminate the catch of the object to be conveyed S on one attachment 112U and the other attachment 112L and the chain stiffening portion 110G is formed, the pair of meshing chains 111U and 111L are connected to each other.
