Description

Description: TECHNICAL FIELD The present invention relates to a conveyor device capable of easily carrying out switching of a transfer speed depending on a work section on the same line conveyor.

(Prior Art) Conventionally, when an assembly line using a conveyor and the like are on the same straight line, a certain section is operated by a human, and a certain section is a hybrid line operated by a machine. It is preferable that the work efficiency is improved by taking measures such as, for example, increasing the speed of the work section of a machine at a low speed and the work section of a machine at a high speed.

In such a case, in a system using a roller conveyor, the individual conveyor devices are combined, that is, a high-speed conveyor device using a high-speed motor is used in a high-speed section, and a low-speed conveyor device using a low-speed motor is used in a low-speed section. Or a conveyor system that transports pallets together with a line by arranging them in series.
An apparatus as shown in JP 598604 is known.

(Problems to be Solved by the Invention) However, in the conventional method, it is necessary to change the speed range of each section when it is necessary to change the configuration of the assembly line or when the machine is to perform human work. When the problem occurs, it is necessary to replace the entire conveyor, which takes time and increases costs.
In the case of the signal, it is necessary to reattach the cam plate extending along the traveling route for changing the speed, and there is a problem that it takes time and effort.

(Means for Solving the Problems) In order to solve the above problems, the present invention supports a roller-mounted shaft having a roller attached to the shaft with a bearing, and moves both ends of the roller-mounted shaft outward from the bearing. Extending to a protrusion, a sprocket can be attached to this protrusion, a number of shafts with rollers of such a configuration are arranged in parallel, and a sprocket is attached to only one of the protrusions of each shaft with rollers, A roller chain is hung between sprockets attached to one protrusion of the shaft with rollers, a high-speed motor is attached to this roller chain, and a roller chain is attached to sprockets attached to the other protrusions of the shafts with rollers. By installing a low-speed motor on the roller chain, the line conveyor on one side It was divided into the speed range.

(Operation) For example, when the present apparatus is composed of two high-speed and low-speed motors and a chain, a sprocket in a certain section is meshed with a high-speed chain, so that the sprocket in that section rotates at a high speed and is connected to the sprocket. The rollers also rotate at high speed. Conversely, when the sprocket is engaged with the low-speed chain and the sprocket engaged with the high-speed chain is removed, the rollers in the section rotate at a low speed. When the sprocket is not engaged with either chain, the rollers do not rotate.

(Example) An example of the present invention will be described based on the attached drawings.

1 to 3 show one embodiment of the present apparatus.
FIG. 1 is a plan view of the apparatus, FIG. 2 is a side view of the same, and FIG. 3 is a longitudinal sectional view of the apparatus as viewed from the front.

In FIG. 1 and FIG. 2, roller chains 3a and 3b are provided on both sides of the line conveyor device 1 so as to correspond to the respective motors. That is, the high-speed chain 3a is connected to the high-speed motor 2a on one side, and the low-speed chain 3b is connected to the low-speed motor 2b on the other side.
And endless tracks so as to enclose the front and rear sprockets 15a and 15b with the roller chain tensioner 4 interposed therebetween.

On the other hand, on the upper part of the apparatus, a number of shafts 6 with rollers are arranged in parallel in a direction perpendicular to the roller chains 3a and 3b, and rollers 7 are integrally connected to the shaft 6 with rollers, and are rotatable on the spot. Has become. This situation will be described with reference to FIG. 3. The roller-equipped shaft 6 to which the roller 7 is attached has both side ends supported by bearings 8. Further, both ends of the shaft with roller 6 extending outward from the bearing 8 are formed as protrusions 6a, and a proket 9 is attached to only one of the protrusions 6a, and is detachably fixed by a nut 10 to be below the sprocket 9. Is the roller chain guide 11 and the chain rail for returning the roller chain
The roller chains 3a, 3b meshed with a number of sprockets are provided around the front and rear sprockets 15a, 15b and the chain rail 12. The sprocket 9 meshes with a high-speed chain in a certain section to form a high-speed area m, and in a certain section meshes with a low-speed chain to form a low-speed area n. This change is made by removing the nut 10.

Next, regarding this handling, as described above, the sprocket in the section to be set is meshed with the required chain side, and the length of the section can be easily changed in the high speed region or the low speed region of the line conveyor device depending on the number of meshed sprockets. Can be adjusted. In the present embodiment, two cases, high speed and low speed, are exemplified, but it goes without saying that more than two speeds are possible.

(Effect of the Invention) Since the present invention is configured as described above, only by replacing the sprocket with the protrusion of each shaft with rollers, the sprocket meshes with the high-speed or low-speed chain, and Since the speed can be easily changed, labor and time for changing the transfer speed of the section, which has been conventionally required, can be saved, and an easy and quick response can be achieved. Further, since the entire system is simplified, the cost is also effectively reduced, for example, by reducing the number of drive motors. The length of the high-speed or low-speed section of the line conveyor device can be easily adjusted by the number of roller-equipped shafts each having a sprocket attached to one side of a roller chain driven by a high-speed or low-speed motor. .
