DETAILED DISCLOSURE OF EMBODIMENTS

[0021] In the following description, the terms relating to a position are considered with reference to a processing machine 100 in the use position, i.e., as it is illustrated in FIG. 1 and FIG. 2.

[0022] The processing machine 100 includes a frame 102, a card feeder 150 and a card receptacle 170.

[0023] Conventionally, the processing machine 100 also includes a processing module and a transport system which includes means for moving the cards from the card feeder 150 to the processing module, then to the card receptacle 170, where the means conventionally include rolls which pinch the cards and motors which drive the rolls in rotation. Thus, the processing module is downstream of the card feeder 150 with respect to the direction of movement of the cards by the transport system and upstream of the card receptacle 170. In the embodiment of the invention depicted in FIGS. 1 and 2, the card receptacle 170 is arranged below the card feeder 150, but it may be arranged in another location.

[0024] In the embodiment of the invention depicted in FIG. 2, the card feeder 150 is secured to the frame 102 and it includes a reservoir 204 in which the cards to be processed are stored. The reservoir 204 is herein delimited by three vertical walls 204a-c, namely a back wall 204c and two lateral walls 204a-b arranged on either side of the back wall 204c. These vertical walls 204a-c are secured to the frame 102 and form, when seen from above, a U, where the lateral walls 204a-b form the branches of the U and where the back wall 204c forms the bottom of the U.

[0025] In the lower portion, the reservoir 204 has a plate 204d secured to the frame 102 and generally horizontal which forms the base of the reservoir 204 and above which the cards to be processed, such as plastic cards, are stored. Thus, the cards are stacked on top of one another and on the plate 204d. Thus, the cards are arranged between the vertical walls 204a-c and on the plate 204d.

[0026] The card feeder 150 herein has a door system 160 according to the invention.

[0027] In the embodiment of the invention depicted in FIGS. 1 and 2, the card receptacle 170 is secured to the frame 102 and it includes a housing 172 in which the processed cards are stored. Like for the reservoir 204, the housing 172 is herein delimited by three vertical walls 172a-c, namely a back wall 172c and two lateral walls 172a-b arranged on either side of the back wall 172c. These vertical walls 172a-c are secured to the frame 102 and form, when seen from above, a U, where the lateral walls 172a-b form the branches of the U and where the back wall 172c forms the bottom of the U.

[0028] In the lower portion, the housing 172 has a plate 172d secured to the frame 102 and generally horizontal which forms the base of the housing 172 and above which the processed cards are stored. Thus, the cards are stacked on top of one another and on the plate 172d. Thus, the cards are arranged between the vertical walls 172a-c and on the plate 172d.

[0029] In this case, the card receptacle 170 has a front wall 172e which is also vertical and which closes, at least partly, the housing 172 so as to stop the cards which fall into the housing 172.

[0030] The processing module is, for example, a printer or an encoding module, etc. The processing module and the transport system will not be described in more detail because they can take on any form known to a person skilled in the art. Similarly, the card feeder 150 and the card receptacle 170 may take on other forms.

[0031] Although the door system 160 is more particularly described as associated with the card feeder 150, a similar door system can be implemented for the card receptacle 170.

[0032] The door system 160 includes a door 162 having a leaf 164 movable alternately between a closed position (FIGS. 1 and 4) and an open position (FIGS. 2, 3, and 5). In the closed position, the leaf 164 forms a front wall of the reservoir 204 and closes it to hold the cards to be processed.

[0033] FIG. 3 shows the leaf 164 in the open position, and FIGS. 4 and 5 show sections at the hinge of the leaf 164 respectively in the closed position and in the open position.

[0034] The door system 160 includes a secondary frame 202 which includes at least one stop 302a-b, 402a-b. The secondary frame 202 is secured to the frame 102 of the processing machine 100, and it may be a portion of the frame 102 of the processing machine 100 or an attached and fastened element.

[0035] The door 162 also includes a shaft 304 secured to the leaf 164, herein via a swan neck. The shaft 304 is mounted movable in rotation about a tilting axis 50 on the secondary frame 202 to enable the rotation of the shaft 304, and therefore of the leaf 164, about the tilting axis 50 between the closed position where the leaf 164 extends vertically and the open position where the leaf 164 extends horizontally.

[0036] In the closed position, the shaft 304 is in the lower portion of the leaf 164 to enable opening of the leaf 164 by gravity.

[0037] The shaft 304 has on its periphery, and for at least one stop 302a-b, 402a-b (herein the stop or stops 402a-b), a projection or protrusion 306 which therefore projects from the shaft 304.

[0038] As shown in FIG. 4, the protrusion 306 is positioned so that in the closed position, there is therefore no contact between the protrusion 306 and the stop 402a-b, and the protrusion 306 is therefore not pressed against the stop 402a-b and no blocking force is exerted by the stop 402a-b on the protrusion 306.

[0039] As shown in FIG. 5, after tilting the door 162, the protrusion 306 is positioned so that, in the open position, there is contact between the protrusion 306 and the stop 402a-b and the protrusion 306 is therefore pressed against the stop 402a-b, and blocking forces are exerted by the stop 402a-b on the protrusion 306 to block it in rotation.

[0040] Thus, with such an arrangement, when the door 162 tilts towards the open position, the protrusion 306 rubs against the stop 402a-b which blocks movement thereof and any possible bouncing.

[0041] In the embodiment of the invention presented herein, the protrusion 306 cooperates with the stop 402a which is above the shaft 304, but with a different arrangement, the protrusion 306 will cooperate with a stop 402b which is below the shaft 304.

[0042] Conventionally, the closed position of the door 162 may be guaranteed by a blocking means, such as a clip secured to the leaf 164 and including a flexible tooth which is inserted into a recess of the secondary frame 202 provided for this purpose.

[0043] On the side of the stop 402a, the shaft 304 herein includes an inclined plane 306a which connects the circular periphery of the shaft 304 and the top of the protrusion 306 so as to form a corner which is inserted between the shaft 304 and the stop 402a.

[0044] In the embodiment of the invention depicted in FIG. 3, there is a protrusion 306 at each end of the shaft 304 to ensure symmetrical blocking and there is thus one stop 402a for each protrusion 306.

[0045] Various arrangements are possible to carry out the rotation of the shaft 304 on the secondary frame 202, such as, for example, a hinge where the protrusion is then arranged on a movable node of the hinge.

[0046] In the embodiment of the invention depicted in FIGS. 3, 4, and 5, the door system 160 includes four pairs of two jaws 302a-b, 402a-b. In the embodiment of the invention, there are two first pairs of two jaws 302a-b, where each first pair is open towards a first direction herein corresponding to the outside of the processing machine 100, and two second pairs of two jaws 402a-b (shown in ghost lines in FIG. 3) where each second pair is open towards a second direction opposite to the first direction, i.e., in this case the inside of the processing machine 100.

[0047] The first pairs are secured to a first element of the processing machine 100, herein to the secondary frame 202, and the second pairs are secured to a second element of the processing machine 100, herein to a cover 102a which is fastened to the secondary frame 202 and which herein forms the front wall 172e of the card receptacle 170.

[0048] The jaws 302a-b, 402a-b are aligned along the tilting axis 50 which forms the hinge axis of the leaf 164.

[0049] The two jaws 302a-b of a first pair are herein arranged next to the two jaws 402a-b of a second pair.

[0050] The opposite orientation between the jaws 302a-b of the first pairs and the jaws 402a-b of the second pairs allows delimiting a channel 404 therebetween which extends along the tilting axis 50 and in which the shaft 304 is inserted to rotate about the tilting axis 50. The dual arrangement of two pairs of jaws 302a-b, 402a-b facing one another allows holding the shaft 304 in the channel 404. For each pair of two jaws 302a-b, 402a-b, there is a jaw 302a, 402a above the shaft 304 and a jaw 302b, 402b below the shaft 304 and aligned vertically with said jaw 302a, 402a.

[0051] The stop herein comprises one/each jaw 402a of a second pair, but it may comprise one/each jaw 302a of a first pair.

[0052] As shown in FIG. 4, in the closed position, the protrusion 306 is herein positioned at the opening between two jaws 402a-b. Hence, there is no contact between the protrusion 306 and a jaw 402a-b.

[0053] As shown in FIG. 5, in the open position, the protrusion 306 is positioned against a jaw 402a. Hence, there is contact between the protrusion 306 and the jaw 402a.

[0054] The door 162 is mounted movable in rotation on the secondary frame 202, between an open position, enabling access to the inside of the reservoir 204 and the deposition of cards on the plate 204d, and a closed position, preventing access to the reservoir 204 while enclosing the cards in the reservoir 204, and vice versa. Thus, the door 164 closes the U formed by the vertical walls 204a-c.

[0055] The door 162 is movable in rotation about a tilting axis 50 which is directed horizontally. Thus, the door 162 can tilt about the tilting axis 50 between the open position and the closed position, and vice versa. In the open position, the door 162 is directed generally vertically and, in the open position, the door 162 is directed generally horizontally.

[0056] The tilting axis 50 is in the lower portion of the door 162 when it is in the closed position. Thus, when the door 162 is maneuvered to the open position, it tilts under the effect of gravity.
