DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a mail enclosing and sealing apparatus and, more particularly, to a mail enclosing and sealing apparatus having an envelope processing function for enabling an envelope being utilized to act at the most suitable mail enclosing condition.
BACKGROUND ART
According to a prior art mail enclosing and sealing apparatus which has been invented by the applicant of the present invention, as shown in FIG. 1, envelopes 1 are taken out one by one from envelope guides 3 of an envelope hopper 2 receiving therein a multiple number of envelopes 1. The envelopes 1 being taken out are supplied, through a series of rollers 4, to a gripper 6 which is mounted on an envelope transporting chain 5 being driven intermittently and waiting at an envelope receiving position A. Then, the gripper 6 moves, in accordance with the movement of the chain 5, the envelope 1 to an envelope opening position B. At the position B, the flap portion of the envelope 1 is opened in the arrow 7 direction by flap opening means known per se. Thereafter, the envelope 1 is transported to an enclosure inserting position C with the flap portion being maintained at the open condition. The opening portion of the envelope 1 is opened widely by opening means 8 such as a vacuum pad and the like, and an enclosure 10 being transported through another route 9 is enclosed in the envelope 1. Then, the envelope 1 enclosing therein the enclosure 10 is transported to an ejecting position D and is ejected in a direction perpendicular to the moving direction of the chain 5 and the route 9 (the direction perpendicular to the paper of the drawing), and the envelope 1 is sealed.
The envelope guides 3, 3 are mounted, as shown in FIG. 2, on blocks 11, 11. The blocks 11, 11 are threadingly engaged respectively with a shaft 12 having left and right hand screw-threads. A knob 13 is mounted on one end of the shaft 12. Thus, by rotatingly adjusting the knob 13, the envelope guides 3, 3 move in the directions of the arrows perpendicular to the longitudinal center line L--L of the apparatus and by the same amount. It will be understood that almost all prior art envelopes have a symmetrical configuration in the left and right as shown in FIG. 2. And the center line of the opening of the envelope 1 coincides with the center line of the envelope 1, and is located on the longitudinal center line L--L of the machine. Thus, various sizes of envelopes 1 can be handled by the machine by locating the envelope guides 3 adjustable symmetrically in the left and right directions with respect to the longitudinal center line L--L of the machine.
However, in one type of recent envelope, particularly for use in direct mails, for easily been opened by the person who received the direct mail, there is provided, as shown in FIG. 3, a flap portion 14 along one side edge of the envelope and perforations defining a cutting line 15 for opening the envelope near to one of the side edges. In such case, an envelope 200 can easily be opened without utilizing a knife and the like by tearing one side of the envelope along the perforations 15. In the envelope 200, the widthwise center-line m--m of the envelope does not coincide with the center-line n--n of the enclosure being provided in the envelope. Thus, when the envelope 200 is utilized in the machine shown in FIG. 2, the center line of the enclosure 10 is located on the center line L--L of the machine, and when the enclosure 10 is moved into the envelope 200, one side of the enclosure 10 overlaps with the flap portion 14 of the envelope by an amount 16, and the one side of the enclosure may abut with the flap portion which may prevent smooth insertion of the enclosure 10 into the envelope 200.
Further, in usual mail enclosing and sealing apparatus, the dimension of the opening of the envelope is determined to be sufficiently larger than the width of the enclosure being inserted into the envelope through the opening, and the opening device such as vacuum pads 8 are located near to opposite side edges of the envelop
