Description

[Detailed description of the invention] The present invention relates to a roller conveyor for work, and its purpose is to be able to work with individual items stopped on the conveyor, and to allow individual items to be moved freely by the operator after the work is completed. To provide an ideal working roller conveyor that allows conveyance to be carried out on a conveyor.

The structure of the present invention will be explained as follows based on the embodiment shown in FIGS. 1 to 5.

In the figure, reference numeral 1 denotes two parallel frames placed on an underframe 2, and between the frames 1 and 1, a large number of support rollers 3 are supported at right angles at equal intervals so as to be freely rotatable. ing.

Reference numeral 4 denotes an endless tensioning member, for example, a belt, which circulates at intervals below all of the support rollers 3, and this tensioning member 4 is attached to the deflection roller 5 at each of the support rollers 3 located at both ends. , 5, and is driven in the direction of arrow 7 in the figure by a drive roller 6 at the lower intermediate portion thereof.

Reference numeral 8 denotes a support roller disposed below each of the support rollers 3 at a position where it can slide into contact with the lower surface of the tension member 4,
Each of the support rollers 8 is rotatably supported at the lower end of each arm 9 which is rotatably attached to the support roller 3 axes, so that it can move back and forth in a fan-shaped manner about the support roller 3 axes as a fulcrum.

Reference numeral 10 denotes an intermediate roller disposed on the rear lower surface of each of the support rollers 3 between the tension member 4 and the tension member 4 at a position where it can come into sliding contact with both. Each mounting plate 11 is rotatably supported by a hole 12 at the rear corner of each mounting plate 11 which is rotatably supported below.

13 is a balance roller rotatably supported at the front corner of each of the mounting plates 11; 14 is a balance roller that is rotatably supported at the front corner of each of the mounting plates 11;
Each horizontal rod 14 is connected to each pedal 16 via each link mechanism 15. By depressing each pedal 16 against each spring 17, each pedal 16 is moved in the direction of an arrow 18 in the figure.

. Now, before starting work, the tension member 4 is always driven in the direction of the arrow 7 in advance.

In this state, each pedal 1 is
6 is pushed up by each spring 17 and each horizontal rod 14 is fixed at the right position in the figure, so each support roller 8
, each intermediate roller 10 and each balance roller 13 are rotating in light contact with the tension member 4.

Therefore, each of the support rollers 3 also rotates in a state of hair idling in the direction of the arrow 19 in the figure, in light contact with the intermediate roller 10.

When the operator depresses the pedal 16 against the spring 17, the link mechanism 15 moves the horizontal rod 14 in the direction of the arrow 18, causing the mounting plates 11 to tilt simultaneously, as shown in FIG. As shown in the figure, the support roller 8 pushes up the tension member 4, the intermediate roller 10 presses down the tension member 4, the tension member 4 is held between both rollers 8 and 10, and the support roller 3 is pushed up through the intermediate roller 10 in the direction indicated by the arrow 19. drive in the direction of.

In this state, the height measurement is fed onto the support roller 3, and the height measurement is conveyed by the support roller 3. Then, when the height measurement reaches the appropriate position of each worker on the conveyor, the pedal 16 is released.

Then, the horizontal rod 14 is returned to its original position by the spring 17, and each mounting plate 11 is also returned to its original position at the same time, and each support roller 3 becomes the idling state shown in FIG. Only the intermediate roller 10 corresponding to these rotates idly while being in contact with the tension member 4 through its hole 12.

Therefore, each height measurement is stopped at a fixed position on the conveyor, so the work can be carried out as is.

When the work is finished, the user depresses the pedal 16 to carry out the completed height measurement to the left side in the figure, and then has the new height measurement carried out from the right side to continue the assembly work.

In the above embodiment, the number of support rollers 3 that can be operated by 16 pedals is 7, but this has no special meaning and this number can be arbitrarily selected and changed depending on the type and size of height measurement. Of course, the length of the entire conveyor may be the length of one pedal 16, and the length can be selected and changed as desired.

Next, another embodiment of the present invention will be described based on FIG. 6. This embodiment is almost the same as the previous embodiment, but the pedal 16 in the intermediate position is removed and manual operation using the pedal 16 is not possible. This method differs in that it is automatically operated by a sensor 20 that detects the movement of height measurement in the previous process (work position), and can be widely adapted to many different work contents.

As described above, the present invention has a rotatably supported support roller, and below each support roller is a support roller suspended from a support roller shaft, and between this support roller and the support roller, together with the support roller. An intermediate roller supported by a mounting plate is supported by sandwiching a tension member that constantly circulates between the two, and a plurality of roller groups supported by this are connected by a horizontal rod at each mounting plate portion, and furthermore, a plurality of roller groups supported by the intermediate roller are connected by a horizontal rod at each mounting plate portion. The roller group, which has been in an idling relationship, can be moved to a driving relationship by being activated by the operator's operation, such as by operating a pedal, so it is possible to work with the height measurement stationary on the conveyor. The height measurement after the work is completed can be carried out on the conveyor as desired by the operator.

Therefore, as described above, work can be performed with the support rollers stopped, improving work accuracy and work efficiency, which is useful for quality control, and contributes to workplace safety without danger. Since the conveyance operation can be carried out in a timely manner, it is convenient because the time each worker has, that is, the working time can be freely set, and there is no need for a transmission in the driving part, which can improve productivity.

Furthermore, it is possible to flow items with different work contents and work models, and it is easy to change the work pattern, so it can be used for multiple purposes, and when not used as an assembly work line conveyor, it can be used as a simple transport conveyor.
It is also an ideal working roller conveyor, as it can be used as an accumulation conveyor to change line functions depending on the purpose.
