Noise-reduced moving pressure deck mechanism

You invention relates to a pressure deck mechanism for for franking machine systems, and in particular to a printing deck with a reduced printing deck compared to the known printing decks Noise level

With the growth of high-speed mail processing machines, there is a growing tendency for high noise levels. "Nowadays, however, machines are preferred which, despite higher Speeds Are Quieter The present invention addresses the problem of noise reduction and shock isolation in the lifting mechanism of the franking machine.

The invention relates to a noise-reduced moving one Print deck mechanism for a franking machine system The pressure deck according to the invention enables a uniform Postage imprint rom franking on 'different thicknesses Mail regardless of the lower thickness · This one

is achieved in part by the highly flexible nature of the deck, which in turn is given by the leaf spring support, and partly also through the expansion bracket and its ter connection to the deck «Another part of the gate of the leaf spring supports is their reduced relative movement. This reduced movement eliminates friction and noise.

The mechanism according to the invention comprises a conveyor belt for transporting the mail items coming into the franking machine, in the near future a movable one, the Poet supporting deck is arranged. The incoming mail is between the conveyor belt and the moving one Deck added. The basin and the conveyor belt are from a hemp frame part supported on noise-reducing dampers or flexible supports is stored.

On the deck and the main frame, spaced apart leaf springs are attached Enable relative movement of the pelvis and thereby reduce the working noise level of the lifting mechanism.

The object of the invention is to create an improved postage meter press deck}

it also depends on a bracket cover mechanism for a Frankiermaachinensjsiem should be provided which is relatively quieter iat as the known Druckdeckmecliaaisaen;

and furthermore it should be noted that the back cover mechanism is butted.

These and other objects of the invention are explained in the following detailed description with reference to FIG accompanying drawings in which

pose with the pressure deck in the depressed position *

Reference is now made to Figures 1 and 2, in showing a postage meter system 10. A letter 11 is, as indicated by the arrow 12, for front end of the system. The letter is picked up by the feed rollers 13 and 13a and between the conveyor belt 14 and the deflectable deck 15 brought. The deck 15 is pressed upward by springs, so that the mail piece is moved by the conveyor belt I4 is detected. The letter 11 then becomes the printing drum 17 a franking unit 18 transported, where it receives the postage imprint.

The deck 15i the conveyor belt I4 »the franking unit 18 as well Most of the other moving parts of the system are all mounted on or on the main support frame part 19. The main frame part I9 has four flange parts 20, which are each located at the corners of the system. These flange parts 20 are all based on flexible ones Cushions 21, which serve to cushion said moving parts and to isolate them from the environment. This cushioning dampens the transmission of noise and shock to and from the system.

The system is also greatly reduced in noise by the leaf springs 22 ', 22 ", 22" · that make the deck I5 resilient prop up.

One leaf spring 22 'acts as a flexible coupling between the lip 23 of the deck 15 and the main frame 19 "

and the two further leaf springs 22 ″ and 22 ″ ^f likewise produce a flexible connection between the deck and the frame 19 and are arranged below the franking unit 18. The latter leaf springs 22 ^W and 22 "· form, as shown in the drawing, a parallelogram»

All leaf springs 22 ·, 22 ", 22" 'have the same structure or shape, the same length and the same Width to allow the deck I5 in translational Wise to evade * Although this translational movement is not purely parallel, it allows one Uniform postage imprint on items of mail with different Thick. So far, this function has been achieved with fixed links. The present Leaf springs 22 ', 22 ", 22" », however, make work much quieter.

In Fig. 3 it is shown how a fairly extensive Letter 24 deflects deck 15, and it can be seen that the deck 15 has remained substantially parallel.

The thickness of the leaf springs can be 22 », 22", 22 "» be different if they have to take loads of different sizes, i.e. the leaf springs 22 ", 22" ' below the postage meter 18 could require a greater thickness than the spring 22 ′ below the lip 23.
