A solenoid 204 mounted on the side 48 acts on a lever 206 mounted on the gate rocket shaft to move the gate to its second position.

The manual return button 208 is used to energize the solenoid 204 (although the solenoid 204 may be actuated by the automatic detection device 44).

The details of the automatic detection device 44 will be explained with reference to FIGS. 14 to 16. The automatic detection device 44 includes the separation device 34 and the gate device 4.
2, at a fixed position with respect to the first common transfer path formed by belt conveyors 136, 138 as shown, transversely spaced apart It is desirable to place it in the space between the belts.

The illustrated automatic detection device has two sensing elements 210 and 210.
, each including a phototube 212 disposed in the exit path of the envelope after extraction, and an opposing light source or light emitting diode 214.

Sensing elements 210, 210 are spaced apart in the direction of the envelope travel path and each detect a predetermined amount of infrared radiation (energy) transmitted through the thickness of a sheet of paper, for example, comprising the main part of an opened empty envelope. It is a response to the state.

When there are two paper thicknesses, e.g. an envelope fold or when the document passes one sensing element 210, the photocell 212
The amount of infrared radiation it receives is sufficient to trigger the attached circuitry.

The data received by the trigger circuit is transmitted to the logic circuit to stop both phototubes 212, 212 at the same time.

Sensing elements 210, 210 are sufficiently spaced along the path of the envelope that both sensing elements will not be deactivated simultaneously when the envelope fold passes, but deactivating both sensing elements simultaneously will cause the envelope to be opened. Indicates that there are documents consisting of enclosed documents or unnecessary items.

The gate solenoid is actuated in response to the detection of a desired predetermined condition by the detection device 1 or the like to eject envelopes, documents, etc. to the front of the extractor.

A logic circuit that accomplishes the above purpose is diagrammed in FIG. 16, with both sensing elements connected to the inputs of NOR gate 216.

When both sensing elements simultaneously detect a desired predetermined condition, such as the thickness of two sheets of paper that simultaneously stops both sensing elements 210, 210, the solenoid 204 is actuated to place the envelope in front of the extractor and place it in front of the operator. emit in the direction.

The drive mechanism operating the envelope feeder, cutter, and separator preferably demagnetizes and stops the electromagnetic clutch 178 each time the gate solenoid 204 is operated, either manually or in response to the automatic detection device 44.

The illustrated clutch circuit includes a timer 222 to disengage the clutch and stop the separator in a predetermined position.

The envelope transported there approaches the envelope extracting position each time the gate solenoid 204 is actuated.

After the envelopes 12, 12 of a predetermined size are opened along one longitudinal edge, the envelopes are stacked in the hopper 24, such as by cutting, such as with a conventional opening machine, with the opened end facing the front of the extractor 10. Let them face each other.

If necessary, operate the crank 62 to move the horizontal rails 56,
Adjust the hopper by lightly contacting the envelope 56 with the first and second side edges 18, 1B on both sides of the envelope.

The rearward tilting of the hopper prevents copper coins or other bulky enclosures from falling out of the envelope.

An envelope 12 is pulled out of the hopper by means of a vacuum pick device 64, 64 and placed on the accelerator plate 52, while the vacuum of the vacuum pick device is shut off by a valve 71.

The envelope transfer section is then actuated to move the envelope 29 toward the cutter 30.
Send an envelope along.

Envelope edge guides 108, 108, which are adjusted so that the first and second side edges 18 of the advancing envelope are in contact with each other, align the envelopes laterally and are connected to a pair of upper feed rollers 90' and a lower feed roller. Guide each side into a nipper between rollers 90.

Envelope edge guides 108, 108 are adjusted to accommodate standard size envelopes therebetween to adjust the distance from each side edge 18 of the envelope to the corresponding cutter ring 88.

The inner distance from each side edge 18 to the corresponding cutting line is envelope edge guide 1
08, 106, and once the side guides are adjusted, the distance cannot be increased even if the length of the envelope is changed.

When an envelope that is slightly longer than the standard size is placed in the cutter, the envelope is turned upward as it enters the cutter by the feed roller.

However, if the length of the envelope is significantly longer than the standard size, the envelope will stop engaging the envelope end guides 108, 106 and will not pass toward the cutter.

When each envelope 12 passes through the cutter 30, the cutter ring 88
, 88 cut upwardly only the lower panel 16 of the envelope due to the spacing between each cutter wheel 88 and its attached anvil wheel.

The depth of each cut is determined by the adjustment screw 99 on each cutter, so that each cutter cuts the full thickness of one envelope.

The lower panel 16 of the envelope 12 thus separates from the upper panel along the successive first and second sides 1B, 18.

In particular, the envelope is cut along the cutting line 32.32 without removing or trimming the enclosure.

Cutting the bottom side of the envelope also creates a pre-cut panel on the bottom side of the envelope, which is one sheet thick and has a first and second side 18,
1B has less deflection than the top panel, which includes a small uncut section.

Therefore, the lower panel better fits the outer shape of the separation drum 112.

The cut envelope 12 fed from the cutter 30 enters the nipper between the vacuum drum 112 and the drum follower 128.

As the envelope 12 leaves the cutter, the back side or the tip of the lower panel 16 opens the vacuum ports 122, 122.
so that it overlaps with

The vacuum port holds the panel tightly down against the circumference of the drum.

The drum follower 128 makes the top panel 14 somewhat stiffer.
and the envelope enclosure follows a portion of the circumference of the drum.

11-13, as the envelope and enclosure C leave the drum follower 128 and the nipper within the drum 122, the enclosure C and top panel 14 will follow a tangential path with respect to the drum 112.

As the drum continues to rotate clockwise, the upper end of the chute 38 enters the gap between the upper and lower panels 14 and 16 containing the enclosure, as shown in Figures 11 to 13, and captures the enclosure C and removes it from the open envelope. , following the path of drum 112.

The upper end of the chute 38 is actuated to crease or fold the upper panel 14 relative to the lower panel 16 toward the travel position.

As the drum 122 continues to rotate, the leading edge of the lower panel 16 is pulled into the nipper between the vinyl roll and the drum and removed from the drum by the strippers 133, 133.
The nipper guides the lower panel into the conveyor 40 along a tangential path with respect to the drum.

The envelope 12 is fed into an automatic detection device 44 for detecting documents, and when it detects that one document or enclosure is missing, the gate device 4
2 is in its first position, the leading edge of the empty envelope engages the arcuate surface on the gates 196, 196, and the envelope is moved along the second transfer common path between the conveyors 134, 136 at the rear of the extractor. The discharged black cloth envelopes are sorted and sent to waste or the like (not shown).

However, when the automatic detection device 44 detects the existence of the document,
The aforementioned logic operates gate device 42 to move the gate device to the second position, or the position shown in phantom in FIG.

At the second position of the gate device, various gates 196,
The surfaces 200, 200 of 196 are conveyor belts 138,
136 so that envelopes and enclosures are ejected from the front of the extractor and out the bottom of the chute toward the operator.

The worker operates the return button 208 to close the solenoid 204.
is excited to change the position of the gate device 42.

Therefore, according to the present invention, envelopes of different sizes can be selected by the envelope end guide 108, and the envelope enclosures can be separated by the separating device 34 and the chute 38. Conveyor 40 without being
If the envelopes are transferred to the first transfer path, the automatic detection device disposed on the first common transfer path detects this, so that the contents enclosed in the envelopes can be reliably extracted and sorted.

Moreover, since the upper and lower panels of the empty envelope remain as one body without being separated, subsequent processing is extremely easy.
