Description

  The present invention relates to an envelope regulating device in an envelope manufacturing machine, and more specifically, before the folding operation of the flap portion of the envelope, which is performed as a process before placing the envelopes after finishing all the processes on the receiving table, The present invention relates to an envelope regulating device that can reliably perform the regulation of the position and orientation of the front end of an envelope.

  In an envelope manufacturing machine, envelopes that are applied in a sealed state, so-called flaps, and transported in a stacked state shifted in a staircase form, are pulled out to one sheet after drying the paste applied to each sealing unit. Then, it is sent to the bending operation position after regulating the position and direction of the front end.

  In addition, conventionally, a device for regulating the position and orientation of the front end of the envelope drawn out to one sheet has conventionally been an envelope transfer belt, a pinch roll lined up above the envelope transfer belt, and the envelope A regulation ruler carrying belt disposed on both sides of the transfer belt in the moving direction along the envelope transfer belt and moving at a constant speed at a speed slower than the movement speed of the envelope transfer belt, and the regulation ruler carrying It is constituted by a regulation ruler carried on the belt at a predetermined interval.

  Then, the envelope drawn out and sent by the envelope pulling device is transferred forward by the envelope transfer belt in the envelope regulating device. At this time, since the moving speed of the envelope transfer belt is faster than the regulation ruler carrying belts on both sides thereof, the envelope quickly catches up with the regulation ruler carried on the regulation ruler carrying belt. Finally, the front end of the envelope hits both regulation rulers and is regulated so that its position and orientation are appropriate.

  By the way, the envelopes sent through the various processing steps up to the envelope pulling device that pulls out and sends one envelope to the envelope regulating device are displaced in the interval between them.

  And if a gap arises in the mutual interval of the envelopes transferred in this way, a timing deviation also occurs in the withdrawal of the envelope addressed to one sheet by the envelope drawer device.

  Despite such a state, conventionally, the envelope transfer belt and the regulation ruler carrying belts on both sides of the envelope transfer belt are both moved at a constant speed.

  For this reason, in the case of envelopes with a normal gap, the timing of delivery is shifted, and the position on the envelope transfer belt in the envelope regulating device is farther from the regulation ruler of the regulation ruler holding belt than the normal position. If it is past the position, the front end of the envelope cannot catch up with the regulation ruler, and therefore the position and orientation of the front end of the envelope cannot be regulated, and conversely, the regulation ruler holding belt is not located at the normal position. If the envelope is too close to the regulation ruler, the front edge of the envelope catches up with the regulation ruler too quickly, and the envelope is pushed further in the state where it hits the regulation ruler. It becomes a situation that cannot be regulated.

  The present invention has been made in view of the above points, and when a deviation occurs in the timing of drawing out by the envelope pulling device due to a gap between the envelopes to be transferred, the envelope transfer belt in the envelope regulating device Envelope regulation in an envelope manufacturing machine that adjusts the moving speed to match the timing shift and moves the front end of the envelope at an appropriate speed that can be accurately regulated by a regulation ruler, thereby enabling reliable regulation. The device is to be provided.

  Thus, the gist of the present invention is that the envelope transfer belt, the pinch rolls arranged above the envelope transfer belt, and the envelope transfer belt on both sides of the moving direction of the envelope transfer belt are arranged. And a regulation ruler carrying belt that moves at a constant speed slower than the moving speed of the envelope transfer belt, and a regulation ruler carried on the regulation ruler carrying belt at a predetermined interval. In the envelope restricting device in the envelope manufacturing machine, the envelope transfer belt is driven by a servo motor, and the front end of the envelope is placed between the envelope transfer belt and the envelope pulling device that sends out the envelope one by one. A detection sensor is provided, and the timing of the envelope that is pulled out and sent by the control device based on a signal from the envelope front end detection sensor is measured, and the measured timing is The number of rotations of the servo motor is controlled by the control device, and the envelope transfer belt is moved at an appropriate speed at which the front end of the envelope can be accurately regulated by the regulation ruler. It is in the envelope control device in the envelope manufacturing machine

  Moreover, as the envelope pulling device having the above-described configuration, the pulling roll rotating at a predetermined speed, the pinch roll disposed above the pulling roll, and the front end of the envelope is guided between the pulling roll and the pinch roll. An envelope pulling device configured with a guide rod is preferable.

  The present invention is configured as described above, and when the timing at which the envelope is pulled out by the envelope pulling device is shifted due to a shift in the interval between the envelopes to be transferred, the moving speed of the envelope transfer belt in the envelope regulating device is set to It is adjusted so as to fit the deviation. Therefore, the envelope transfer belt can be moved at an appropriate speed at which the front end of the envelope can be accurately regulated by the regulation ruler, and reliable regulation can be performed.

It is a schematic explanatory drawing which shows the process after the pasting to the sealing part of the envelope in an envelope manufacturing machine.
