Abstract
Abstract An article feed mechanism for use in association with a franking device which operates on mail, comprises a feeding mechanism which includes an article feed path which is oriented so that it may be connected over a feed path of the franking device and which includes two separately driven conveyor sections. The first conveyor is driven by a drive motor and comprises a plurality of drive rollers which operate on the articles which are arranged in a stack at a stacking area and delivers them one at a time to the second conveyor mechanism which includes a pressure drive roller acting to drive the lowermost one of the articles under a sliding apron and then for advancing it into association with a driven roller cooperating with another overhead roller. A first sensor is located between the pressure roller and the cooperating over and under rollers and it acts when an article is advanced to disconnect the drive motor for the first conveyor. After the article leaves the sensor the sensor acts on a second motor to slow down a second driving conveyor. A second sensor is located downstream of the first sensor and it acts when an article approaches it to rapidly decelerate the second drive motor for the second conveyor.

Claim 1
Independent Claim
423 words
An article feed mechanism for use in association with another device for operating on a flat article as it is fed along an operating path, particularly a franking machine which operates on mail, comprising: means defining an article feed path adapted to be associated with the operating path of the device; a stacking area plate in said article feed path adapted to receive flat articles of different size stacked one on top of another; a lateral wall adjacent said stacking area plate; a baffle plate having a lower edge spaced from said stacking area plate by a distance to allow at least one article to pass said baffle plate on said article feed path; first conveyor means disposed along a portion of said article feed path upstream of said baffle plate for feeding articles along said portion of said article feed path, a lowermost flat article being pressed against said first conveyor means by the weight of the articles received on said stacking area plate; first drive means connected to said first conveyor means to drive said first conveyor means; second conveyor means disposed along a portion of said feed path downstream of said first conveyor means for feeding an article; second drive means connected to said second conveyor means to drive said second conveyor means at selected speeds; a flexible hold-back apron having a part resting on a portion of said second conveyor means; first sensor means connected to said first drive means and being located along said feed path adjacent said second conveyor means and acting to stop said first drive means when an article is fed along said feed path to said first sensor means; second sensor means connected to said second drive means and adapted to be connected to the device and acting to stop the second drive means and start the device, said first and second sensor means being located in said article feed path direction downstream of said hold-back apron; said first sensor means being connected to said first drive means and said second drive means, said first sensor means producing a signal for reducing the conveying speed of said second conveyor means by acting on said second drive means when a trailing edge of the article passes said first sensor means; and connection means connected to said first and second drive means and connected to the device so that a signal connection is provided between the device and the feed mechanism for restarting said first and second drive means of said first and second conveyor means.

An article feed mechanism for use in association with another device for operating on a flat article as it is fed along an operating path, particularly a franking machine which operates on mail, comprising: means defining an article feed path adapted to be associated with the operating path of the device; a stacking area plate in said article feed path adapted to receive flat articles of different size stacked one on top of another; a lateral wall adjacent said stacking area plate; a baffle plate having a lower edge spaced from said stacking area plate by a distance to allow at least one article to pass said baffle plate on said article feed path; first conveyor means disposed along a portion of said article feed path upstream of said baffle plate for feeding articles along said portion of said article feed path, a lowermost flat article being pressed against said first conveyor means by the weight of the articles received on said stacking area plate; first drive means connected to said first conveyor means to drive said first conveyor means; second conveyor means disposed along a portion of said feed path downstream of said first conveyor means for feeding an article; second drive means connected to said second conveyor means to drive said second conveyor means at selected speeds; a flexible hold-back apron having a part resting on a portion of said second conveyor means; first sensor means connected to said first drive means and being located along said feed path adjacent said second conveyor means and acting to stop said first drive means when an article is fed along said feed path to said first sensor means; second sensor means connected to said second drive means and adapted to be connected to the device and acting to stop the second drive means and start the device, said first and second sensor means being located in said article feed path direction downstream of said hold-back apron; said first sensor means being connected to said first drive means and said second drive means, said first sensor means producing a signal for reducing the conveying speed of said second conveyor means by acting on said second drive means when a trailing edge of the article passes said first sensor means; and connection means connected to said first and second drive means and connected to the device so that a signal connection is provided between the device and the feed mechanism for restarting said first and second drive means of said first and second conveyor means.
Claim 3
Dependent Claim
62 words
An article feed mechanism according to claim 1, wherein said means defining an article feed path extends outwardly from said feed mechanism and is engageable over the operating device, said operating device comprising a franking machine and coupling means defined between said franking machine and said feeding mechanism and including an electrical plug unit for coupling these parts together mechanically and electrically.
Claim 4
Dependent Claim
81 words
An article feed mechanism according to claim 1, wherein each of said first and second conveyor means includes a plurality of conveying members successively arranged in a conveying direction along said feed path and which come into contact with the article, a downstreammost one of said conveying members of said first conveyor means being spaced from an upstreammost one of said conveying members of said second conveyor means by less than a length of the article along said article feed path.
Claim 5
Dependent Claim
37 words
An article feed mechanism according to claim 1, wherein said second conveying means comprises a plurality of rotatable members arranged along said feed path in succession for producing a conveying speed which increases in the conveying direction.
Claim 6
Dependent Claim
