- Reference numeral 6 denotes a laterally rotating sprocket in which the above-mentioned protruding pins 5 or teeth 61 to which the rollers 51 are engaged are provided at equal intervals in the circumferential direction. It is fixed to a drive shaft 62 that is oriented vertically. Therefore, by rotating the drive shaft 62 with a motor or the like (not shown), the lateral rotation sprocket 6 rotates in the horizontal direction (including the horizontal direction or the direction of inclination slightly inclined with respect to the horizontal surface). In addition, when the roller 51 conforms to the JIS or ISO standard, the lateral rotation sprocket 6 can also use a sprocket based on the standard.
- a horizontal rotating sprocket 6 is arranged in the middle of the conveyor transport line to form a spiral transport line.
- the driving force of the laterally rotating sprocket 6, which engages with the protruding pin 5, is transmitted to the conveyor via the protruding pin 5, and the top plate unit 201 is moved while being guided by the circular guide rail E. Sa
- the transfer driving force is applied to the conveyor at an appropriate position in the conveyance path.
- the traction load on the conveyor can be dispersed and reduced, thereby improving the durability of the conveyor and further enabling the conveyor to operate smoothly.
- any of the above-described embodiments since one top plate unit is provided with two bending joints, it is possible to reduce the turning radius in the U-turn portion of the comparator. Therefore, it is possible to construct a transfer line and a storage line that can make a U-turn rotation with a narrow width, so that the equipment area of the conveyor can be reduced and the space of the transfer path can be used. Also, as shown in the second embodiment, the combination of the laterally rotating sprocket 6 and the top plate unit 201 makes it possible to increase the overall length of the conveyor and to circulate it in multiple stages, thereby achieving high integration. It is possible to configure a storage and transfer device of different degrees. Industrial applicability
- a sphere housing portion is provided at two places in the front-rear direction of the top plate unit, and a connector having both ends formed into a sphere is loosely fitted into the sphere housing portion.
- the top play units are connected at two locations by a connecting mechanism equivalent to a universal joint or a pole joint.
- Each top plate unit thus obtained can be tilted in a free direction within a predetermined angle range with respect to the axis in the transport direction, and can be rotated in the circumferential direction about the axis.
- the distance between the joints that bend on the transport line is shortened because of the divided length, and the rotation can be performed by drawing a polygon that is more circular, so the difference in the peripheral speed due to the difference in the radius of the corner and the side There is little pulsation (commonly known as breathing) generated from, and smoother transport is possible.
- sprocket joints are provided on both outer left and right sides of the spherical housing formed on the top plate unit, and the sprocket joints are gears with a fixed pitch, that is, sprockets with a standard tooth profile specified in JIS standard. Since it is possible, the transport conveyor can be easily unitized or standardized for each part.
- the top plate unit is capable of pivoting in a 360 ° direction, such as obliquely, vertically, or downwardly, about the transport surface about the center line in the traveling direction, the top plate unit reciprocates and rotates to the endless in upper and lower stages.
- the top plate unit can be turned upside down by 180 degrees and run with the top of the plate facing up on the lower return path of the transport conveyor.
- Both the upper and lower stages of the endless conveyor can be configured as conveyor lines for the conveyed goods, and the space on the conveyor path can be used effectively.
- the top plate unit provided with a transporting object clamping mechanism can transport, for example, tilt, sideways or sideways while transporting the transported product (for example, an upwardly opened container) that is transported by being clamped and transported on the top plate unit. It is possible to perform operations such as tilting the container downward and discharging the contents contained in the container in the middle of transportation.
- a device for setting up a dedicated line for discharging the contents and relocating the transported goods to those dedicated lines This eliminates the need for a transfer line, making it possible to construct a transport line that is also excellent in equipment economy.
- the action of one or more laterally rotating sprockets arranged at appropriate places in the middle of the transport path is provided. It is easy to change the direction of the conveyor in the L-shape or U-shape, and one or more horizontal rotating sprockets arranged at appropriate places in the middle of the conveyance path can be set up and down. In addition, it is possible to transfer a large amount of conveyed products while reducing the floor space of the conveyor equipment.
