Description

  The present invention relates to a conveyor device that supports and conveys an object to be conveyed at both ends in the width direction of a conveyance path, and a conveyor facility including the conveyor device.

  Conventionally, for example, both ends in the width direction of the conveyance path are parallel to the conveyance direction such as a roller conveyor unit or a chain conveyor unit so as to support and convey the object to be conveyed at both ends in the width direction of the conveyance path. A conveyor device in which a conveyor unit is installed is known (see, for example, Patent Document 1). In such a conveyor device, two conveyor units are usually connected to each other by a plurality of connecting members parallel to the width direction. The two conveyor units are attached to a common base frame. The connecting member may directly connect the two conveyor units, or may indirectly connect the two conveyor units by connecting the portions of the base frame that support the respective conveyor units. There is also. In this way, the two conveyor units at both ends in the width direction of the transport path are directly or indirectly connected by the connecting members parallel to the width direction, thereby increasing the support rigidity of the two conveyor units and the rigidity of the entire conveyor device. It has been. In addition, the two conveyor units are usually driven by a common drive shaft parallel to the width direction, so that the two conveyor units convey the object to be conveyed at an equal conveying speed. . Further, a motor for driving a common drive shaft is often installed between two conveyor units in a posture in which the direction of the motor shaft is parallel to the width direction. These drive shafts and motors are also usually attached to the base frame.

  In this way, a conveyor device in which two conveyor units are connected directly or indirectly by a connecting member parallel to the width direction, and the two conveyor units, the drive shaft, and the motor are attached to a common base frame is rigid. In addition to being high and compact, there is an advantage that installation work is easy.

  However, since there are a connecting member, a drive shaft, a motor, and the like between the two conveyor units, there is a situation that dust or the like tends to collect on the floor surface under the conveyor device, and periodic cleaning is necessary. On the other hand, since there are connecting members, drive shafts, motors, etc. between the two conveyor units, it is impossible for an operator to enter between the two conveyor units to perform the cleaning work. Even if it was able to enter, the work space was small and cleaning work was not easy. Also, the conveyor unit needs regular maintenance and inspection, but it is impossible for the operator to enter between the two conveyor units to perform maintenance and inspection of the conveyor unit. Even if it was possible to enter, the work space was small and maintenance and inspection work was not easy. For this reason, there are many cases where work such as cleaning of the floor surface under the conveyor device, maintenance of the conveyor unit, inspection, etc. must be performed from the outside (in the width direction) of the conveyor device, and there is a problem that work efficiency is low. It was. In addition, the floor surface under the conveyor device may not be sufficiently cleaned from the outside of the conveyor device. In addition, there is a problem that it is necessary to secure a work space that allows an operator to move outside the conveyor device, and that a large installation space is necessary for the conveyor device. In addition, the length of the connecting member and drive shaft is determined based on the width dimension of the object to be conveyed, but even if the outline of the specification of the object to be conveyed is determined at an early stage, the exact specifications such as the width dimension will not be determined. In some cases, it takes time, which makes it difficult to start production of the conveyor device and to cope with a short delivery time.

  The present invention has been made in view of the above-described conventional problems, and includes a conveyor device and a conveyor facility that facilitate floor cleaning, conveyor unit maintenance, inspection, and the like and contribute to saving installation space and shortening delivery time. The purpose is to provide.

  The present invention is a conveyor apparatus in which conveyor units parallel to the conveyance direction are installed at both ends in the width direction of the conveyance path in order to support and convey the object to be conveyed at both ends in the width direction of the conveyance path. Each conveyor unit is provided with a leg portion configured to support the conveyor unit and be fixed to a horizontal floor surface in a portion avoiding the central portion in the width direction of the conveyance path. The above-mentioned object is achieved by a conveyor device configured such that all the components are installed in a portion avoiding the central portion.

Therefore, operations such as cleaning of the floor surface on which the conveyor device is installed and maintenance and inspection of the conveyor unit are easy. In addition, since all the components are installed in a portion avoiding the central portion in the width direction of the conveyance path, dust or the like is unlikely to accumulate on the floor surface under the conveyor device. Further, it is not necessary to provide a space for operations such as cleaning, maintenance and inspection of the conveyor unit on the outside (in the width direction) of the conveyor device, which contributes to saving of installation space. In addition, since there are no connecting members or drive shafts whose length is determined based on the width dimension of the object to be conveyed, manufacture of the conveyor device is started even if the width dimension of the object to be conveyed is not determined. Can contribute to shortening the delivery time.

  In addition, the leg portion has a bottom plate portion fixed to a horizontal floor surface, the bottom plate portion protrudes from a position directly below the conveyor unit toward the center portion in the width direction, and avoids the center portion in the width direction of the conveyance path. It is good to be configured to be installed in the part.

  If the bottom plate of the leg protrudes from the bottom of the conveyor unit toward the center in the width direction, the conveyor units at both ends in the width direction of the transport path are not connected by a connecting member or the like parallel to the width direction. Also, each leg unit can reliably fix each conveyor unit to a horizontal floor surface in a stable posture. In addition, the bottom plate portion is configured to be installed at a portion avoiding the central portion in the width direction of the conveyance path, and the bottom plate portion is installed along the floor surface. The portion protruding toward the center of the direction does not substantially interfere with operations such as cleaning, maintenance and inspection of the conveyor unit.

  The motor and the rotation of the motor shaft are arranged so that the direction of the motor shaft is parallel to the transport direction on the portion of the bottom plate of the leg that protrudes from directly below the conveyor unit toward the center in the width direction. It is preferable to provide a geared motor that is combined with a transmission that outputs by converting the rotation into rotation of the output shaft parallel to the width direction.

  Since the motor of this geared motor is arranged so that the direction of the motor shaft is parallel to the conveying direction, protrusion in the width direction is suppressed, and a large space (in the width direction) is secured between the two conveyor units. The The geared motor is compact because it is provided on the bottom plate of the leg.

  Moreover, the height adjustment fixing mechanism which has the function to adjust the installation height with respect to a floor surface may be provided in the some location in each leg part.

  Thus, if the leg part is provided with the height adjustment fixing mechanism, the height of the conveyor units at both ends in the width direction of the conveyance path can be easily adjusted to the same height. Moreover, the installation angle of the conveyor unit can be adjusted by providing height adjustment fixing mechanisms at a plurality of locations in each leg.

  In addition, a plurality of transport paths are arranged in the width direction, and conveyor units parallel to the transport direction are installed at both ends in the width direction of each transport path, and installed at the end of the adjacent transport path on the adjacent side. The two conveyor units and the leg portions that support them may be integrated.

  In this way, by combining the two conveyor units installed at the end portions on the adjacent sides of the adjacent conveyance paths and the leg portions that support them, the support rigidity of the two conveyor units that are integrated is further increased. Can be increased. Further, since there is no gap between the two conveyor units installed at the adjacent ends of the adjacent conveyance paths, the installation space for the conveyor device can be further saved.

  In the present invention, the conveyor device according to any one of the above is installed on a horizontal floor surface, and a portion corresponding to a central portion in the width direction of the conveyance path on the horizontal floor surface is completely opened upward. The above object is achieved by equipment.

The base member 204 is also a rectangular parallelepiped box, and the shape of the upper surface is substantially the same as the shape of the bottom plate portion 158 in which the leg portions 120 and 122 and the leg portions 124 and 126 are integrated. A through hole through which the bolt 68 of the height adjustment fixing mechanism 60 is inserted is formed in the upper surface portion of the base members 202 and 204, and is screwed with the bolt 68 on the lower surface side of the upper surface portion of the base members 202 and 204. The height adjustment fixing mechanism 60 is fixed to the base members 202 and 204 by nuts. The base members 202 and 204 are fixed to the floor surface 12 with bolts or the like (not shown).

  Since the base members 202 and 204 are box bodies, the heights of these transport paths can be increased while maintaining high support rigidity of the conveyor units 16, 118, 116, and 18. Further, the base members 202 and 204 are box bodies whose upper surface has the same shape as the bottom plate portion 58 of the leg portions 20, 22, 24 and 26 and the bottom plate portion 158 of the leg portions 120, 124, 122 and 126. Compact and hard to collect dust. Although FIG. 12 shows an example in which the box base members 202 and 204 are applied to the second embodiment having a plurality of conveyance paths, only one conveyance path is provided as in the first embodiment. In this case, the base member 202 may be installed between the leg portions 20, 22, 24, 26 and the floor surface 12.

  Further, in the third embodiment, the height adjustment fixing mechanism 60 is adopted as in the first and second embodiments. However, when a box base member is used, it is shown enlarged in FIG. The height adjustment fixing mechanism 260 may be adopted. The height adjusting and fixing mechanism 260 includes a bolt 262 that passes through a through hole in the bottom plate portion 58 (158) and a through hole in the upper surface portion of the base member 202 (204), and a bolt 262 on the lower surface side of the bottom plate portion 58 (158). A nut 264 to be screwed, a nut 266 to be screwed to the bolt 262 on the upper surface side of the upper surface portion of the base member 202 (204), and a nut to be screwed to the bolt 262 on the lower surface side of the upper surface portion of the base member 202 (204). 268. Since the height adjustment fixing mechanism 260 has a simple configuration including only bolts and nuts, it contributes to cost reduction.

  In the first to third embodiments, the conveyor units 16, 18, 116, and 118 are roller conveyor units. However, for example, a conveyor unit of another driving mechanism such as a chain conveyor unit or a belt conveyor unit is provided on the conveyance path. The present invention is also applicable to a conveyor device installed at both ends in the width direction.

  INDUSTRIAL APPLICATION This invention can be utilized for the conveyor apparatus provided with this, and the conveyor apparatus which supports and conveys a to-be-conveyed object in the both ends of the width direction of a conveyance path.
