Description

  The present invention relates to a technique for inspecting an enclosed matter enclosed in an envelope in an enclosure sealing apparatus for enclosing and enclosing the enclosed matter in an envelope, and more specifically, a technique for inspecting the protrusion of the enclosed matter to the flap portion of the envelope. About.

  Conventionally, printing companies that manufacture a large number of envelopes encapsulating and enclosing the enclosed items automatically encapsulate and enclose the enclosed items in the envelope when enclosing and enclosing the enclosed items in order to increase production efficiency. The device is used.

  If the enclosed item enclosed in the envelope is a corporate advertising medium or the like, it may be less necessary to inspect the enclosed item enclosed in the envelope, but personal information (for example, In the case of a description such as (Usage details), there is a possibility that personal information may be leaked due to a mistake in enclosing the enclosed item.

  For example, in Patent Document 1, the theoretical thickness of an envelope in which the enclosed material is enclosed is calculated, and the theoretical thickness and the actual thickness are compared. An enclosure sealing system that inspects whether there is an excess or deficiency of the enclosed item enclosed by the envelope by determining that the enclosure is abnormal when the difference is larger than a predetermined value is disclosed.

  In addition, if there is a folding failure in the enclosed item that is folded by a folding machine, the reliability of the automatic enclosing and sealing device may be remarkably reduced, such as occurrence of an enclosed sealing failure. An enclosed sealing device that can accurately determine the quality of the folded state is disclosed.

  However, if the envelope is sealed with the envelope protruding from the flap, the envelope will appear to protrude from the envelope, and some personal information printed on the envelope may leak. However, there has been no disclosure of an invention that can detect the protrusion of the envelope to the flap portion of the envelope after the envelope is sealed in the envelope.

  Then, an object of this invention is to provide the enclosure sealing apparatus which can test | inspect the protrusion of the enclosure to the flap part of an envelope, after enclosing an enclosure in an envelope.

1st invention which solves the subject mentioned above is provided so that the transmission unit which transmits an ultrasonic wave to the flap part of the envelope with which the enclosed thing was enclosed, and the transmission unit may be countered, and the intensity of the received ultrasonic wave at least constituted ultrasonic sensor and a receiver to measure, after the enclosure mechanism for enclosing the enclosures in the envelope, placed at a position passing through the flap portion of the front of the envelope being sealed, wherein the ultrasonic sensor The receiving unit stores the intensity of the ultrasonic wave when only the flap portion of the envelope exists between the transmitting unit and the receiving unit as a reference intensity, and when the intensity of the received ultrasonic wave is lower than the reference intensity, the envelope It is an enclosed sealing device characterized in that it is determined that the enclosed matter has protruded from the flap portion .

  When the envelope protrudes from the flap portion of the envelope, the envelope overlaps the flap portion of the envelope, and the intensity of the ultrasonic wave received by the receiving unit of the ultrasonic sensor according to the present invention overlaps the flap portion of the envelope. If the intensity of the ultrasonic wave when only the flap part of the envelope is present is set as the reference intensity, the protrusion of the enclosed matter to the flap part of the envelope can be inspected. Further, since the intensity of the ultrasonic wave is not affected by the color of the envelope or the enclosed item, it is not necessary to change the setting for each item, the preparation time is reduced, and the productivity is improved.

  Further, when it is determined that the envelope has protruded from the flap portion of the envelope, the apparatus is stopped, so that the envelope in which the envelope has protruded from the flap portion of the envelope can be prevented from being mixed into the product.

  From here, embodiments of the present invention will be described to the extent that a person skilled in the art of the present invention can understand the contents of the invention and implement the invention. The embodiment described below is only one embodiment of the present invention, and the present invention is not limited to the embodiment described below, and various modifications and changes are possible.

  FIG. 1 is a diagram illustrating an enclosing / sealing device 1 according to this embodiment. The enclosure sealing device 1 of this embodiment is a device that automatically performs the process of enclosing and sealing the enclosed material 3 in the envelope 2, and has a function of inspecting the protrusion of the enclosed material 3 to the flap portion 20 of the envelope 2. It is characterized by being. The sealed sealing device 1 includes various mechanisms such as a feed mechanism and a folding mechanism of the envelope 2, but in FIG. 1, a description of a function for inspecting the protrusion 3 of the envelope 3 to the flap portion 20 of the envelope 2 is provided. Only the necessary mechanism is shown.

  On the line 15 of the sealing device 1 according to the present embodiment, after the sealing mechanism 12 that seals the enclosed material 3 in the envelope 2, an ultrasonic wave is used to determine the overlapping state of the flap portion 20 of the envelope 2. A sonic sensor 10 (for example, an ultrasonic double sheet detection sensor) is installed. In FIG. 1, the ultrasonic sensor 10 is installed after the gluing mechanism 13 that forms the glue portion 22 in the flap portion 20 of the envelope 2 in which the enclosed material 3 is enclosed. And the gluing mechanism 13 may be used.

  FIG. 2 is a diagram for explaining the installation state of the ultrasonic sensor 10. As illustrated in FIG. 2, the ultrasonic sensor 10 that determines the overlapping state of the flap portion 20 of the envelope 2 using ultrasonic waves includes a transmission unit 101 that transmits ultrasonic waves, and an ultrasonic wave that is transmitted from the transmission unit 101. And receiving unit 100 that determines the overlapping state of the flap portion 20 of the envelope 2 by measuring the intensity of the received ultrasonic wave.

  In this embodiment, in order to inspect the protrusion of the envelope 3 to the flap portion 20 of the envelope 2, the transmission unit 101 is installed so that the ultrasonic wave hits 4 mm above the folding portion 21 of the envelope 2, and the reception unit 100 is installed facing the transmission unit 101, and a gap of about several tens of mm is provided between the transmission unit 101 and the reception unit 100. Moreover, in this embodiment, when the envelope 2 passes between the transmission unit 101 and the reception unit 100, the holding plate 14 is provided in the sealed sealing machine 1 so that the envelope 2 does not flutter.

  FIG. 3 is a diagram for explaining the contents that the ultrasonic sensor 10 determines the overlapping state of the flap portion 20 of the envelope 2. FIG. 3A is a diagram illustrating a case where the flap portion 20 of the envelope 2 is not present. In the case where the flap portion 20 of the envelope 2 is not present between the transmission unit 101 and the reception unit 100, the ultrasonic wave transmitted by the transmission unit 101 is illustrated. Reaches the receiving unit 100 without attenuation, so that the intensity of the ultrasonic wave received by the receiving unit 100 is maximized.

  FIG. 3B shows a case where the enclosed object 3 does not overlap the flap part 20 of the envelope 2. In the case where the enclosed object 3 does not overlap the flap part 20 of the envelope 2, the transmission unit 101 is shown. Since only the flap part 20 of the envelope 2 exists between the receiving unit 100 and the ultrasonic wave transmitted by the transmission unit 101 is absorbed by the flap part 20 of the envelope 2, the ultrasonic wave received by the receiving unit 100 is received. The intensity is attenuated from the maximum intensity.

And the receiving unit 100, the flap part 20 and the enclosed object 3 of the envelope 2 exist, and the ultrasonic wave transmitted from the transmitting unit 101 is absorbed by the flap part 10 and the enclosed object 3 of the envelope 2, so that the receiving unit The intensity of the ultrasonic wave received by 100 becomes an intensity further attenuated from the intensity of the case where the envelope 3 does not overlap the flap portion 20 of the envelope 2.

  As described above, when the envelope 3 protrudes from the flap portion 20 of the envelope 2, the intensity of the ultrasonic wave received by the receiving unit 100 of the ultrasonic sensor 10 becomes the smallest, so that the receiving unit 100 includes the transmitting unit 101. The intensity of the ultrasonic wave when only the flap part 20 of the envelope 2 exists between the receiving unit 100 and the receiving unit 100 is stored as a reference intensity. If the intensity of the ultrasonic wave received by the receiving unit 100 is lower than the reference intensity, the flap of the envelope 2 is stored. It determines with the protrusion of the enclosure 3 to the part 20 having generate | occur | produced.

  For example, as shown in FIG. 2, by arranging the transmitting unit 101 and the receiving unit 100 of the ultrasonic sensor 10, it is possible to detect the protruding item 10 with a protruding amount of 10 mm for the enclosed item 3 that protrudes straight from the folded portion 21 of the envelope 2. Further, the enclosure 4 protruding obliquely from the folded portion 21 of the envelope 2 can be detected with an amount of protrusion of 13 mm.

  If the receiving unit 100 of the ultrasonic sensor 10 determines that the enclosure 3 has protruded from the flap portion 20 of the envelope 2, it inputs a predetermined signal to the control unit 11 of the enclosing sealing device 1, and the enclosing sealing device 1. When a predetermined signal is input from the receiving unit 100 of the ultrasonic sensor 10, the control unit 11 performs a process of stopping the sealing device 1, and the envelope 2 in which the enclosed material 3 protrudes from the flap portion 20 is added to the product. Prevent contamination.
