[0016]
In the envelope conveyor 26, one chain 40 is wound around two sprockets (not shown), and envelope feed claws 41 are fixed to the chain 40 at predetermined intervals. This predetermined interval is set to be equal to or longer than the length of the envelope 22. An envelope receiving plate 42 is disposed above the chain 40, and the envelope feeding claw 41 projects through the envelope receiving plate 42. The envelope 22 is placed on the envelope receiving plate 42 and is pushed by the envelope feeding claw 41 and conveyed. The sprocket that drives the chain 40 of the envelope conveyor 26 is also intermittently rotated to convey the envelope 22 intermittently.
[0017]
The envelope flap opening device 27 opens the flap 22A of the envelope 22. Since the envelope 22 is supplied with the flap 22A closed by the envelope supply device 25, the envelope flap opening device 27 is required.
[0018]
The envelope opening device 28 is installed at the sealing position A of the envelope conveyor 26, and adsorbs the front and back surfaces of the envelope 22 by a lower suction cup and an upper suction cup (both not shown) that can be raised and lowered. Is opened.

The envelope stacking device 34 is located on the envelope conveyor 26, and pushes up the envelopes 22 sealed after the inclusions 21 are sealed from the bottom upward and stacked to stack a predetermined amount.
[0022]
The control device 35 controls the operations of the enclosure supply device 23, the enclosure conveyor 24, the envelope supply device 25, the envelope conveyor 26, and the enclosure insertion device 30. When the inclusion 21 is, for example, personal information paper, the number and size of the inclusion 21 vary from person to person, and this information is stored in the storage unit 44 connected to the control device 35. The control device 35 operates the corresponding inclusion supply device 23 among the inclusion supply devices 23 based on the information for each individual, and supplies the inclusion 21 onto the inclusion conveyor 24.
[0023]
The storage unit 44 has a speed table 45. The speed table 45 stores a speed pattern that varies the sealing speed of the sealed object 21 by the sealed object insertion apparatus 30 in accordance with the form of the sealed object 21, that is, the thickness (number of sheets) and the size of the sealed object 21. ing. For example, as shown in FIG. 1B, this speed pattern is such that the enclosure speed v of the enclosure insertion device 30 continuously changes in inverse proportion to the number n of the enclosure 21 or the enclosure 21 is the reference number. When it is (for example, 5 sheets) or less, the enclosure speed v of the enclosure insertion device 30 is set to a predetermined value or more, and when it is the reference number or more, the enclosure speed v is set to a predetermined value or less. Is inversely proportional in stages according to the number of inclusions 21. Further, this speed pattern is also proportional to the size of the enclosure 21 in the same manner as described above, with the enclosure velocity v of the enclosure insertion device being inversely proportional to the vertical and horizontal dimensions of the enclosure 21 in a continuous or stepwise manner (dimensions). Is larger, the encapsulation speed v is decreased).
[0024]
The control device 35 determines the enclosure speed of the enclosure insertion device 30 when encapsulating the enclosure 21 from the speed table 45 based on the information for each individual related to the enclosure 21 stored in the storage unit 44, and encloses the enclosure. The object insertion device 30 is controlled. The enclosure insertion device 30 inserts the enclosure 21 into the envelope 22 at the enclosure speed determined as described above, and encloses the enclosure 21.
[0025]
According to the above-described embodiment, the control device 35 controls the inclusion insertion device 30 to correspond to the number n (thickness of the inclusion 21) and the size of the inclusion 21 enclosed in one envelope 22. Thus, since the enclosure material insertion device 30 changes the enclosure speed v of the enclosure material 21, for example, the enclosure material insertion device 30 has the enclosure speed v changed in inverse proportion to the number n of the enclosure materials 21. Can be sealed smoothly inside. For this reason, regardless of the form (number n or size) of the enclosure 21, the enclosure 21 can be satisfactorily enclosed in the envelope 22, and the occurrence of an enclosure mistake or an enclosure jam can be prevented.
[0026]
Next, a second embodiment of the sealing device according to the present invention will be described with reference to FIG. In the first embodiment, information such as the number and size of the inclusions is stored in the storage unit 44. However, in the second embodiment, these pieces of information are attached to the inclusions as barcodes. The point to keep is different. That is, in this encapsulating and sealing apparatus, the encapsulated material 21 in which a barcode (not shown) in which information such as the number n of collated materials 21 and the size of the encapsulated material 21 is recorded is attached to the surface of the enclosed material 21 is processed. A barcode reader 51 (shown by a chain line in the figure) as a form detector is installed between any one of the inclusion supply devices 23 or between each of the inclusion supply devices 23 and the inclusion conveyor 24. Yes. The barcode reader 51 reads information recorded on the barcode while the inclusion 21 is supplied from the inclusion supply device 23 onto the inclusion conveyor 24.
[0027]
Based on the barcode information read by the barcode reader 51, the control device 35 determines the enclosure speed v of the enclosure insertion device 30 from the speed table 45, and operates the enclosure insertion apparatus 30 at this enclosure speed v. Thus, the inclusion 21 on the inclusion conveyor 24 is enclosed in the envelope 22 on the envelope conveyor 26.
[0028]
Also in this embodiment, since the inclusion 21 on the inclusion conveyor 24 can be smoothly enclosed in the envelope 22 on the envelope conveyor 26, the inclusion 21 can be placed in the envelope 22 without causing an encapsulation error or jamming. Can be sealed well.
