Description

  The present invention relates to an inter-mounting-surface height adjustment mechanism and a transfer device that can stably transfer an object between a first mounting surface and a second mounting surface in a transfer region.

  As is well known, for example, when an actual can (object) filled with contents in a cylindrical can body is arranged in an upright manner in the filling process, it is processed in a cleaning process or the like. Generally, the alignment state is once released.

  And, when trying to align real cans again in an upright state, it is necessary to transport a large amount in a short time. By retaining, the buffers are aligned while being secured, and conveyed to the next process (for example, an inspection apparatus).

  In this way, when aligning an actual can that is upright and in an accumulator state, pressure is applied to the actual can in the accumulator state, and the actual can is moved and inserted between other actual cans by the pressure. It was common to align.

  However, when pressure is applied to an actual can for alignment, the actual can may be deformed by receiving an external force, and there is a limit to increasing the alignment speed by applying pressure.

  Therefore, in the width direction, the actual can is transported along the transport direction by using the speed difference transport device configured so that the transport speed sequentially increases from one side to the other side in the width direction of the transport unit. A technique using a speed difference conveyer that aligns while widening the interval between actual cans by moving from one side to the other side is disclosed (for example, see Patent Document 1).

  In addition, when aligning various objects such as actual cans, not limited to the above-mentioned speed difference conveyor, it is necessary to increase the interval in the conveying direction while sequentially transferring the objects from the low speed conveyor to the high speed conveyor. is there.

  For this reason, it is necessary to stably transfer the object between the mounting surfaces of the different conveying means, and the height of one mounting surface and the other mounting surface in the transfer region is in a predetermined positional relationship. In order to maintain and transfer the object stably, it is common to install a height adjusting member such as a guide bar for adjusting the position in the height direction below the conveying means.
