Abstract

PURPOSE: To mark a break visually, by providing a deflecting means in order to stack an article by a stacking apparatus, by giving a visual discontinuety property of the article to an article stacking body, by abutting on the selected article of an article group. CONSTITUTION: When a letter having a break in the code is output from a delivery device 175, a rotary solenoid 216 rotates a link 220 in the direction of the arrow A by a motor controller 171. By the rotation of the link 220, a link 206 to which the rotation is transmitted through a link 228 is rotated. As a result, a deflector plate 202 is rotated from the first position with the common face with a registration wall 145, to the second position, where it meets the envelope having the code break. Consequently, this envelope is slipped to the side with respect to the piling body of other envelopes.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to a code-breaking mechanism for a stacking device that receives a series of articles, and more particularly to a cord-breaking mechanism for a stacking device that receives a series of articles, and in particular for creating discontinuities in the article stream according to changes in selected parameters in the article stream. Concerning the code break mechanism for creating .

[Conventional technology]

In article processing systems, the final treatment step is generally the collection of the treated articles. For example, in conventional mail processing systems, stackers are used to collect envelopes as they exit the shipping machine. Generally, this stacking device receives and stacks envelopes one after another. An operator synchronously removes the stacks of envelopes that have accumulated on the machine and packages them in preparation for delivery by a shipping agent, such as the United States Postal Service (USPS).

[Problem to be solved by the invention]

Shipping agents, such as the USPS, offer special discounts to shippers for mail that is pre-sorted by zip codes, for example. Thus, for example, when processing mail as pre-sorted by zip codes, the stacking equipment operator is provided with means for visually marking zip code changes or breaks in the flow of mail entering the equipment. It is advantageous to add it to

[Means to solve the problem]

It is an object of the present invention to provide a code breaking mechanism suitable for use in stacking equipment.

A preferred stacking device has a deck fixedly supported in the housing so as to be inclined rearwardly by 5 degrees. An alignment wall is secured to the housing and extends generally perpendicular to the deck. A lap wall is slidably attached to the housing at one end.

[For production]

The zip cord breaking mechanism has a deflection bracket rotatably mounted within the opening in the matching wall. The plate is coplanar with the alignment surface of the alignment wall in the first or second normal position. A nod, responsive to control signals from the controller, is secured within the housing and engages the deflection plate through the link such that actuation thereof rotates the deflection plate from a first position to a second position.

When this plate is in the second position, the envelope that nails the break to the zip cord is shifted laterally. The envelope is laterally offset relative to the stack of envelopes so that the operator can visually see the discontinuity in the zip code.

The motor controller 17] synchronously controls the operating speeds of the stacking device 12, the tunnel 216, and the feeder 175 so that, for example, a 5-inch envelope fed by the feeder leaves a space of about 0.775 inches between the leading edges. so that they enter the stacking device so that they are juxtaposed. These envelopes are fed by belts 55, 57, 59 driven by motor 49 under yoke roller 167 via belt 83 and shaft 53, so that the front edge of the previous envelope touches surface 1]5 of the stacking wall. The stacked walls are aligned almost perpendicularly to the wall. Subsequent envelopes are made approximately parallel to the previous envelope. This positioning of the envelope is facilitated by the edge engagement of the envelope with the snap hubs 101, 103, 1.57.

When a letter that causes a break in the code is issued from the feeder 175, the motor controller 171 causes the rotary solenoid 216 to rotate the link 220 in the direction of arrow A. This rotation of link 220 is transmitted through link 228 causing link 206 to rotate. link 20
6 pivots deflection plate 202 from a first position coplanar with registration wall 145 to a second position where it encounters an envelope with a coat break on the route.

This envelope is therefore laterally offset relative to the stack of other envelopes.

When the envelopes are stacked vertically, the hub 101, 1.03°15
The engagement of 7 with the edge of the envelope causes the folding walls to move outward. Rods 1.17, 119, 121, 160 support the stacked envelopes against this movement. Envelopes with code breaks remain offset laterally while the envelopes overlap.
