料の加工具位置決め機構に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for disposing a plurality of rollers in the same row, such as a pick-up roller, a crease roller, and a slot roller in a pick-up cutter or crease slot machine for continuous sheet materials such as corrugated paperboard. The present invention relates to a mechanism for positioning processing tools for sheet-like materials, which are positioned at a predetermined distance from each other.

るとともにタイムロスの多いものであつた。 Conventionally, such a positioning mechanism is known in which one screw shaft is provided for each movable member and the required positioning is performed by rotating and stopping the screw shaft. However, in such a configuration, one screw shaft is required for each moving member as described above, which makes the structure extremely complicated and requires a large space, especially when there are a large number of moving members. In addition, since the positioning operation is complicated, it is easy to select the screw shaft to be operated or operate incorrectly, which is inconvenient in handling and causes a lot of time loss.

て移動する。(Operation) When the driven body is moved to one side by the drive device, the clutch member of one driven body engages with the clutch member of the corresponding cylindrical body, and the rotation of the cylindrical screw body about the rotation axis is engaged. will be stopped. Therefore, the cylindrical screw body moves in a direction corresponding to the rotation by being screwed into the rotating shaft, and the yoke that supports the processing tool moves along the guide shaft. When the driven body is moved from this state to the other side by the drive device, the clutch member of the one driven body is disengaged, and subsequently the clutch member of the other driven body is moved to the corresponding cylindrical shape. The cylindrical screw body is rotated together with the rotating shaft by engaging with the clutch member of the screw body. This stops the movement of the cylindrical screw body,
The yoke that supports the processing tool also stops at a fixed position. Next, when the driven body is moved in the opposite direction by the drive device, the yoke moves from the home position along the guide shaft, contrary to the above.

減少できる。(Effects) (a) Even during continuous rotation of the rotating screw shaft, the processing tool can be stopped independently at any position or moved from the stopped position only by moving the driven body by the drive device. Even if there are a large number of processing tools arranged in a machine, it is no longer necessary to provide the same number of rotating screw shafts for each processing tool, and it is sufficient to provide a single rotating screw shaft common to them, simplifying the equipment. In addition, the positioning work of each processing tool can be performed by remotely controlling each drive device, thereby eliminating the need for direct manual work, thereby reducing wasted human resources and time.

に沿つてヨークとともに移動するものであり、
回転螺軸自体が移動に要する動力を提供するも
のであるから、移動のための別個の駆動装置を
要しないので構造がさらに簡略化され、かつ保
守が容易となる。(b) The processing tool moves together with the yoke along the rotating screw shaft by forward and reverse rotation of the rotating screw shaft,
Since the rotating screw shaft itself provides the power required for movement, a separate drive device for movement is not required, further simplifying the structure and facilitating maintenance.

に行うことができる。C. The clutch member of the driven body and the clutch member of the cylindrical screw body are engaged and disengaged by simultaneously moving both driven bodies in the same direction, and this movement has the effect of disengaging the clutch member of one of the driven bodies. The action of engaging the clutch member of the other driven member can be performed simultaneously. As a result, the drive mechanism for operating the clutch and its associated members can be a single unit common to both driven bodies, which further simplifies the structure of the positioning mechanism, and further simplifies the switching operation of the clutch. Therefore, the control mechanism can be simple. Furthermore, when the clutch member of one driven body is in the engaged state, the clutch member of the other driven body is reliably maintained in the disengaged state, so that the processing tool can be stopped and moved reliably without malfunction. can.
