Abstract

PURPOSE:To freely and safely cross a conveyer by providing a pair of lifters capable of freely elevating at plural spots of the conveyer and a horizontal conveyer below the lifters in a coupling conveyer of a long conveyer of automation line manufacture form. CONSTITUTION:In case of processing a printed substrate 4 continuously through the preceding process and the succeeding process 2, a work 4 is fed from the preceding process 1 into a coupling conveyer 3, and when a sensor 11 is operated, an elevating conveyer 31 is rotated so that the work 4 operates a sensor 34. Thus, the elevating conveyer 31 is lowered and stopped at the same level with a horizontal conveyer 32, and the conveyers 31, 32 are driven by operation of a sensor 35 so that the work 4 is transferred onto the conveyer 32. Subsequently, when a sensor 38 is operated, the work is transferred onto a conveyer 33 and lifted to be delivered to the succeeding process 2. In this arrangement, the coupling conveyer is lowered to cross the conveyer safely and easily.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a connecting structure for long conveyors used in manufacturing multiple processes in an automated line, and particularly relates to a connecting structure for a long conveyor used for manufacturing multiple processes in an automated line. This relates to the structure of a connected conveyor that can be freely traversed.

[Conventional technology]

The structure of a long conveyor in a conventional automated line is
In order to minimize the number of products in progress, a manufacturing system is adopted in which multiple processes are carried out on one long conveyor, and it is not uncommon for lines with many manufacturing processes to exceed the 10 axis.

[Problem that the invention seeks to solve]

Regarding the structure of the conventional conveyor mentioned above, it is well known that as much as possible, finishing the assembly etc. on one conveyor is the best way to minimize work in progress and improve work efficiency, which greatly contributes to cost reduction. However, if a long conveyor, for example a conveyor of 100 m or more, is installed at a predetermined height,
In order to go around to the other side of the conveyor, you have to go around one of the short ends from your current position, which requires a lot of effort and time. , stepping stools were set up on both sides of the conveyor and people could jump over it, but each had its own problems, such as being dangerous.

[Means for solving problems]

The present invention solves the above-mentioned problems and provides a structure of a connected conveyor that facilitates the traversal of the conveyor. This is achieved by comprising a pair of lifters that can be raised and lowered and a conveyor that is driven horizontally between the pair of lifters, so that the conveyor can be easily moved across the horizontally driven conveyor.

[Effect]

The structure of the above-mentioned connected conveyor is that a connected conveyor consisting of a pair of lifters that can be raised and lowered and a horizontal conveyor installed at the bottom is installed at several locations on a long conveyor or between different processes, and an operator can operate the conveyor. This is a connected conveyor that allows people to cross freely and safely.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the structure of a connecting conveyor according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a schematic configuration diagram for explaining an embodiment of the structure of a connecting conveyor according to the present invention.

When processing a component to be processed, such as a printed circuit board 4, in the pre-process 1 and post-process 2 in succession, when the printed circuit board 4 as the processed component is fed from the pre-process conveyor 1 to the connecting conveyor 3 as shown by arrow A, The sensor 11 installed at the last part of the conveyor in the pre-process 1 operates, and the elevating conveyor 3
1 rotates, the printed circuit board 4 moves up and down the elevator conveyor 31.
When the sensor 34 moves upward, the sensor 34 operates, and the rotation of the elevator conveyor 31 stops, and at the same time, the elevator conveyor 31 descends in the direction of arrow B. When the elevating conveyor 31 reaches the sensor 35, the elevating conveyor 31 stops descending, and both the elevating conveyor 31 and the horizontal conveyor 32 start rotating. And printed circuit board 4
When the transfer to the horizontal conveyor 32 is confirmed by the ON/OFF of the sensor 37, the elevating conveyor 31 rises and the sensor 36
Stop and return to the current state. Then, the printed circuit board 4 travels in the direction of arrow C on the horizontal conveyor 32, and the sensor 38
By N-OFF, the lifting conveyor 33 rotates and the printed circuit board 4 is transferred to the lifting conveyor 33. When the printed circuit board 4 further reaches the sensor 39, the lifting conveyor 3
At the same time as the sensor 3 stops, it rises in the direction of the arrow, and the sensor 40
When it stops, it starts rotating at the same time, and the sensor 41 turns on -
When the conveyor 2 in the downstream process starts rotating due to the OFF state, and the printed circuit board 4 moves in the direction of arrow E and is transferred to the conveyor in the downstream process 2, the elevator conveyor 33 starts to descend by the sensor 43 and stops by the sensor 42. and returns to the initial state of operation. The printed circuit board 4 is subjected to a post-process 2 process.

With such a configuration, if a sufficient distance is left between the elevating conveyors 31 and 33 for a person to pass through, the work can be performed easily and efficiently.

In this embodiment, the connecting conveyor is provided between processes, but it may be provided not only between processes but also between long conveyors of the same process. Furthermore, although the conveyor has been explained using electronic parts as an example, it can be applied not only to electronic parts but also to all fields such as machinery.

〔Effect of the invention〕

As is clear from the above explanation, according to the structure of the connected conveyor according to the present invention, the conveyor can be made long and several processes can be performed on a series of conveyors, which improves work efficiency and is effective in reducing worker fatigue. It is.
