Description

  The present invention relates to a plastic bottle conveyor that conveys plastic bottles to, for example, a plastic bottle crusher or a compression device thereof.

  In general, a PET bottle conveyor that transports PET bottles to a PET bottle crusher or a compression device thereof needs to drop the PET bottles from a certain height. For this reason, in order to process a PET bottle continuously, conventionally, as described in Patent Document 1, for example, it is lifted to a necessary height by an inclined conveyor or a special conveyor and conveyed.

Japanese Patent No. 3705594

  As described above, since the conventional PET bottle conveyor uses an inclined conveyor, a suitable distance is required to secure a necessary height. For this reason, it is difficult to secure a space for people and forklifts and other work vehicles to move under the conveyor, and there is a problem that the conveyor becomes an obstacle to the passage of people and forklifts and other work vehicles.

  In view of the above problems, an object of the present invention is to provide a plastic bottle conveyor having a configuration that reduces the degree of obstacles to traffic and work of people and work vehicles.

The drive motor 21 fixes a suspension ring 39 that connects a connection tool 38 such as a hook of the hoisting device 36 to a position that is an upper portion of the center of gravity including the motor frame 20.

  In FIG. 3, reference numeral 40 denotes a receiving cover provided at a position located in the concave portion 8 in the lower part of the vertical conveyor frame 5. The receiving cover 40 includes a semicircular arc-shaped cross-section 40a having an arc shape centering on the shaft 12 of the driven sprocket 10 and side plate portions 40b at both ends thereof. The arc-shaped cross-section 40a is formed at the tip of the bucket 16. It has a shape along the movement trajectory. The receiving cover 40 receives a PET bottle introduced from the insertion port 5f, and the PET bottle introduced into the receiving cover 40 is scooped up by a bucket 16 attached to a sprocket chain 15 that rotates about a shaft 12. is there. Further, the receiving cover 40 plays a role of receiving a plastic bottle from the rising bucket 16 and scooping it up by the bucket 16 again.

  When carrying the PET bottles into the crusher 3 by this conveyor, the drive sprocket 9 is driven to rotate by the operation of the drive motor 21 and the sprocket chain 15 is rotated to move the bucket 16 up and down. The PET bottle is introduced from the insertion port 5 f at the lower part of the vertical conveyor frame 5 and is introduced into the receiving cover 40. The PET bottle put into the receiving cover 40 is squeezed by the bucket 16, lifted by the bucket 16 rising at the front portion of the vertical conveyor frame 5, and reversed at the top, as shown in FIG. The plastic bottle 42 falling by reversing falls along the inclined surface 16d which is the back surface of the bucket 16 preceding the previous one, and a chute 43 provided on the vertical conveyor 5 so as to be positioned on the horizontal conveyor 2. Is dropped onto the horizontal conveyor 2. The PET bottles 42 conveyed on the horizontal conveyor 2 are guided by the chute 4 from the end of the horizontal conveyor 2 and are put into the crusher 3.

  Thus, since the plastic bottle conveyor of this Embodiment comprised the plastic bottle conveyor by the vertical conveyor 1 and the horizontal conveyor 2, the height which the person and a work vehicle can pass the height of the horizontal conveyor 2 under it. In addition, since the occupation area of the vertical conveyor 1 is small, the PET bottle conveyor is generally used for traffic and work of people and work vehicles. The degree of hindrance can be greatly reduced.

  Moreover, in this embodiment, the PET bottle 42 which falls when the bucket 16 of the vertical conveyor 1 is reversed at the top is the back surface of the bucket 16 which descends in advance of the tip of the bucket 16 at the top. Since it falls to the horizontal conveyor 2 along the inclined surface 16d, the PET bottle 42 falling from the top of the vertical conveyor 1 can be smoothly transferred to the horizontal conveyor 2 without providing another member as a guide member to the horizontal conveyor 2. Can be migrated to. In addition, the chute 43 guides the plastic bottle 42 that falls from the back of the preceding bucket 16 so as to surely fall on the horizontal conveyor 2.

  In the present embodiment, the motor frame 20 on which the drive motor 21 is mounted is attached to the vertical conveyor frame 5 so that the vertical position can be adjusted by fastening and loosening the bolt 32 and the nut 30 below the drive sprocket 9. The power transmission sprocket chain 25 is stretched by the own weight of the drive motor 21 and the motor frame 20 in the loosened state 32, the bolts are fastened in the stretched state, and the motor frame 20 is fixed to the vertical conveyor frame 5, thereby The tension of the transmission sprocket chain 25 can be easily adjusted.

  Further, in the present embodiment, when adjusting the vertical position of the drive motor 21, when the drive motor 21 is serviced, or when the sprocket chain 25 is replaced, the bracket 35 is connected via the hoisting device 36. By supporting the drive motor 21, workability in replacing the sprocket chain 25 and maintaining the drive motor 21 is improved.

  Moreover, in this Embodiment, since the receiving cover 40 was provided in the lower part of the vertical conveyor frame 5, the PET bottle swept by the receiving cover 40 from the floor surface in which the vertical conveyor 1 was installed is efficiently squeezed by the bucket. In addition, when a PET bottle falls from the upper bucket 16, the receiving cover 40 can receive the PET bottle, and the subsequent bucket 16 can scoop up the PET bottle, so that the conveyance efficiency is improved.
