Description

  The present invention relates to a net conveyor in which an endless net is stretched between a driving side rotating body and a driven side rotating body by a conveyor chain or a conveyor belt and circulated together with the conveyor chain or the conveyor belt.

  Patent Document 1 (Japanese Patent Laid-Open No. 10-250816) discloses such a net conveyor, in which a driving sprocket for driving a conveyor chain and a driving motor for rotating the driving chain are moved up and down integrally by propulsion using screws. Thus, a structure is disclosed in which the tension of the endless net can be adjusted.

  By the way, as described in, for example, Patent Document 2 (Japanese Patent No. 2949662), the present applicant provides, manufactures and sells a water removal machine using a net conveyor.

  1 to 6 show an example of a water remover provided by the present applicant. This dewatering machine has a lower air jet unit B and a net conveyor C installed in the upper part of the main body housing A, and the upper unit cover D can be opened and closed on the main body housing A up and down above the net conveyor C. Further, a soundproof cover E that covers the upper unit cover D from above is mounted on the main body housing A so as to be freely opened and closed.

  The lower air injection unit B is a flat rectangular lower air box 1 with a large number of spin nozzles 2 facing upward and individually pivotable, between the upper Ca and lower Cb of the net conveyor C. The main body housing A is removably installed at the top.

  The upper unit cover D has a box shape with an open lower surface facing the net conveyor C, and is hinged to the upper rear portion of the main body housing A by a hinge 4 so as to be freely opened and closed. As shown in FIG. 6, in the upper unit cover D, an elevating plate 5 is mounted so as to be movable up and down by a plurality of guide rods 3 suspended from the ceiling. The height of the elevating plate 5 can be adjusted by a height adjusting handle 5a provided outside the ceiling of the upper unit cover D. On the lower side of the lift plate 5, an upper air injection unit F is mounted, which is detachably mounted on the lower surface of the flat rectangular upper air box 6 with a large number of spin nozzles 7 facing downward. A side air injection unit G is suspended from the upper air injection unit F. The side air injection unit G separates a plurality of bottomed cylindrical bodies 9 mounted so as to be turnable with the spin nozzles 8 facing sideways away from each other in the conveying direction of the conveyor C, and further communicates the upper air box 6 with the interior thereof. It is suspended from the lower surface.

  As shown in FIG. 3, the lower air box 1 and the upper air box 6 are supplied with air from the two blowers 10 corresponding to each of the lower air box 1 and the upper air box 6. The spin nozzle 2 is transported on the conveyor C and jets air upward from below while turning to the water removal target 50 that has entered the upper unit cover D, and a number of spin nozzles 7 of the upper air jet unit F are The air is jetted downward from above while turning to the water removal target 50 conveyed on the conveyor C, and the plurality of spin nozzles 8 of the side air injection unit G are water removal targets conveyed on the conveyor C. While turning to the object 50, air is jetted from the side.

  In such a dewatering machine, if the deposits removed together with the water from the water removal target adhere to the mesh of the endless net 11 of the net conveyor C, it is not preferable for hygiene, and therefore, particularly high-grade hygiene management is required. In the case of water removal objects (foods, etc.), the endless net is removed and immersed in a cleaning solution or sterilizing solution for cleaning and sterilization, which may be performed several times a day. is there.

  However, in the conventional water remover, the bearing of the driven side rotating body of the net conveyor C (the driven side sprocket wheel when a conveyor chain is used, or the driven side pulley when a conveyor belt is used) is fixed. If the mounting bolt is removed or loosened, or if a tension sprocket wheel or tension pulley is provided separately, the shaft stopper must be loosened and the endless net must be loosened and removed. Also, after cleaning, the endless net must be stretched again and adjusted to return to the original tension state, so that the work is very troublesome and requires skill, and only a limited number of workers can perform it. It was.

In the thing of the above-mentioned patent document 1, although tension can be adjusted with a screw, since the drive sprocket and the drive motor for rotating the same are moved integrally, the structure is complicated and the attachment / detachment of the endless net is difficult. There is a problem.
JP-A-10-250816 Japanese Patent No. 2949662

  Therefore, the problem of the present invention is that the endless net can be relaxed and tensioned easily by a single operation with the handle without adjustment, and the endless net can be easily attached and detached without requiring skill. To provide a conveyor.

  The present invention provides a bearing for a driven side rotating body in a net conveyor in which an endless net is stretched between a driving side rotating body and a driven side rotating body by a conveyor chain or a conveyor belt and circulated together with the conveyor chain or the conveyor belt. Attach it to the conveyor frame so that it can move back and forth in the direction of stretching the conveyor chain or conveyor belt, and attach a tension / relaxation switching tool to the conveyor frame that the connecting rod slides back and forth with the crank mechanism by rotating the handle. The connecting rod is connected to the bearing, and the handle is rotated to move the bearing back and forth together with the connecting rod, whereby the tension and relaxation of the endless net can be switched.

  The tension / relaxation switching tool allows the connecting rod to slidably pass through a guide tube fixed on the board, and pivotally support the handle on the board. The handle and the connecting rod are connected by a crank link. What you did is fine.

  This net conveyor is suitable for use in the above-described net conveyor for a water remover.

  According to the net conveyor of the present invention, the bearing of the driven rotor is movable, the bearing and the handle of the tension / relaxation switching tool are connected via the connecting rod, and the handle is rotated to connect the bearing. By moving the bearing back and forth together with the rod, the tension and relaxation of the endless net can be switched, so that the tension and relaxation of the endless net can be easily switched with one operation with no need for adjustment. The net can be easily attached and detached without requiring skill.

  If the tension / relaxation switching tool as specified in claim 2 is used, it is possible to construct a net conveyor that exhibits the above-described effects by simply attaching the substrate to the conveyor frame and connecting the connecting rod to the bearing. Can do.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  7 and 8 show the main part of the net conveyor of this embodiment used in the water remover, and FIGS. 9 to 11 show the tension / relaxation switching tool used in this net conveyor.

  7 and 8, the entire net conveyor C is mounted on the conveyor frame 12 in the water remover as shown in FIGS. 1 to 6, and the conveyor chains 13 on both side edges of the endless net 11 are driven sprockets. The endless net 11 is circulated together with the conveyor chain 13 by being stretched between the wheel 14 and a driving sprocket wheel (not shown) and being rotated by a motor (not shown). Yes.
