Apparatus for measuring the stiffness of mail articles on the principle of measuring deflection of a beam in bending comprises a rectilinear conveying portion for conveying the mail articles, a deflection roller disposed in a staggered offset manner between two wheels having deformable rims in such a manner as to form a substantially triangular peak on the rectilinear conveying portion, and an inlet ramp that is disposed upstream from the peak and that follows the upward slope of the peak.

In a transport method, a leading object is diverted from an initial direction to a target direction and transported and stopped by a guiding facility. If the following object has reached a specific position during transport in the initial direction, the guiding facility triggers continuation of the transport of the leading object, diverts the following object to the target direction, and transports the following object in the target direction. If a determined sum of the thicknesses of the objects is less than or equal to a predetermined thickness limit, continuation of the transport of the leading object is triggered such that the following object moves onto the leading object when diverted and overlaps the leading object when transported in the target direction. If the thickness sum is greater than the thickness limit, continuation of the transport of the leading object is triggered such that a gap exists between the objects.

A method is provided for preventing flat mail pieces having excessive thickness or stiffness from entering a mail processing machine wherein flat mail pieces are held on opposite sides and conveyed by paired conveyor belts around one or more curves, including one curve which is the sharpest curve in the mail processing machine. Such a method includes the steps of conveying a singulated stream of flat mail pieces one at a time though a test curve upstream from the sharpest curve of the mail processing machine, the test curve including an angled section at which each mail piece tends to bend, determining the thickness of each mail piece, determining the stiffness of each mail piece by measuring deflection of one of the belts of the test curve as an end portion of the mail piece is passing through the angled section, which deflection is in excess of deflection caused by the thickness of the mail piece as it passes between the belts, and diverting a mail piece out of the mail processing machine before it reaches the sharpest curve of the mail processing machine if predetermined stiffness and thickness criteria are exceeded by the thickness and stiffness of the mail piece. The angled section defines an angle less severe than the sharpest curve, whereby a mail piece that would likely jam the mail processing machine at the sharpest curve can pass through the test curve without jamming.

An arrangement for measuring the rigidity of flat items with the aid of a conveying path in which the items are transported separately by means of conveying belts, wherein the conveying path has a straight section and a curved section and wherein the conveying belts are made of an eleastic material in the region of the curved section and at least one rigidity sensor is provided for measuring the deflection of the conveying belts caused by the item passing through a predetermined position of the curved section, and further including at least one thickness sensor in the region of the straight section, and an evaluation device is provided for determining the rigidity of an item passing through from the values obtained by the thickness and rigidity sensors.

Apparatus and method for checking the contents of envelopes and sorting envelopes and other documents according to thickness. The envelopes or other documents are fed along a predetermined path, the thickness of each envelope or document is checked as it travels along the path, and any envelope or document having a thickness greater than a predetermined thickness is diverted from the path.
摘要:
A method and apparatus are described for automatically checking envelopes for objects which would interere with an automatic postal mail sorting operation. The envelopes are moved between inflated rollers and changes in the roller pressures caused by objectionable objects in the envelopes are detected to control an envelope diversion gate.
摘要:
An automatic flat-article separating apparatus for mail handling is disclosed. The apparatus has an article transport path, an ejecting route, a suction belt, a thickness detector installed on the transport path and a roller assembly for compressing the flat article to the suction belt. The thickness detector determines the acceptable limits of the material passing on the transport path and when the article is within that predetermined range, the roller is activated to compress the flat article.

A system for automatically sorting a mailpostal matter and a method thereof are provided. The system for automatically sorting a mailpostal matter includes a mailpostal matter supply unit configured to convey two inputted mailpostal matters by controlling a distance between the two inputted mailpostal matters to be equal to a distance between carriers when the two mailpostal matters are inputted through one inlet at the same time, a mailpostal matter inserting unit, configured to insert the two conveyed mailpostal matters into two crossbelt carriers which are continuously empty at the same time when the two mailpostal matters are conveyed from the mailpostal matter supply unit, and a crossbelt carrier configured to move the two mailpostal matters inserted from the mailpostal matter inserting unit.
摘要:
An apparatus for determining the stiffness of mail pieces includes a bar or similar deflector for contacting a mail piece conveyed past the bar by a conveyor system, and vibrates when in contact with a passing mail piece, either due to the impact of the mail piece or by the action of a device which causes the deflector to vibrate before the mail piece hits it. A sensor measures a parameter indicative of change in the vibrations of the deflector and generates a signal indicative of the measured parameter. A processor, e.g. programmable controller or circuit, receives the signal from the sensor and determines a stiffness value for the mail piece based on decay in vibrations of the deflector caused by contact with the mail piece.
