Referring to fig. 8-18, card transport apparatus is used to store and transport cards 100. Card 100 is typically a rigid plastic with a higher stiffness than conventional paper materials. The card conveying device comprises Rong Kacang, rong Kacang, wherein the card accommodating cavity 1 is used for storing a plurality of cards 100, a larger number of cards 100 are generally stored in the card accommodating cavity 1, the cards 100 are stacked in the vertical direction, when the cards are discharged, the cards 100 at the bottommost layer are output one by one, and the cards 100 above fall one by one under the action of self gravity. Specifically, the front end of the card accommodating cavity 1 is provided with a card inlet 11, the card inlet 11 is used for allowing the card 100 to enter and exit the card accommodating cavity 1, the card inlet 11 can be arranged on the side wall of the card accommodating cavity 1 and also can be arranged on the bottom wall of the card accommodating cavity 1, in order to facilitate the card 100 to pass through the card inlet 11, optionally, the card inlet 11 is arranged on the side wall of the card accommodating cavity 1, and the lower eave of the card inlet 11 and the bottom wall of the card accommodating cavity 1 are located in the same plane. The height of the card inlet is between the thickness of one card 100 and the thickness of two cards 100, that is, the card inlet 11 allows only one card 100 to pass through, so that the card 100 located at the lowest position will pass through the card inlet 11 first. Further, it should be noted that the upper and lower directions in the present embodiment refer to directions perpendicular to the bottom wall of the card holding chamber 1, and in some embodiments, the bottom wall of the card holding chamber 1 is parallel to the horizontal plane, so that the upper and lower directions in the present embodiment refer to vertical directions, and in the present embodiment, do not refer to vertical directions, specifically, the bottom wall of the card holding chamber 1 is an inclined plane, and the upper and lower directions in the present embodiment also refer to directions perpendicular to the bottom wall of the card holding chamber 1. In this embodiment, with one end of the card 100 facing the moving direction thereof as the front end and the other end as the rear end, the specific structure of the bottom wall of the card accommodating cavity 1 is that the bottom wall of the card accommodating cavity 1 is an inclined plane with the front end being lower than the rear end, so that one side of the bottom wall of the card accommodating cavity 1 close to the card inlet 11 is lower, and the card 100 in the Rong Kaqiang is convenient to slide towards the card inlet 11 under the action of gravity.

With continued reference to fig. 8-18, the card transport apparatus further includes a first drive roller 2 and a second drive roller 5, the first drive roller 2 being rotatably disposed at Rong Kacang and being disposed at a bottom wall of the high Yu Rongka cavity 1 and for driving the card 100 toward the second drive roller 5, the second drive roller 5 being disposed at the card inlet 11 and for driving the card 100 toward the outside of the card cavity 1, the first drive roller 2 and the second drive roller 5 being driven by a drive member such as a motor. In this embodiment, the card 100 located at the lowest position in the card accommodating chamber 1 is called a card to be transported, the other cards 100 located in the card accommodating chamber Rong Kaqiang are called card in-hopper, and the card transporting apparatus transports only one card 100 at a time out of the card accommodating chamber 1, that is, the card to be transported, and when the card to be transported is transported out of the card accommodating chamber 1, the card in the lowest hopper, that is, the card 100 located at the lowest position in the card accommodating chamber 1 becomes a new card to be transported.

With continued reference to fig. 8-18, the card conveying apparatus further includes a supporting boss 3, where the supporting boss 3 is convexly disposed at the rear end of the card accommodating cavity 1, in this embodiment, convexly disposed at the rear end of the bottom wall of the card accommodating cavity 1, and in other embodiments, convexly disposed at the rear end sidewall of the card accommodating cavity 1, and the first driving roller 2 is located between the card inlet 11 and the supporting boss 3, that is, the supporting boss 3 is disposed at a side of the first driving roller 2 away from the card inlet 11. The supporting boss 3 is used for supporting the card 100, when the card 100 at the lowest position is conveyed to be separated from the first driving roller 2, the rear end of the rest card 100 can be supported on the supporting boss 3, namely, when the conveyed card is separated from the first driving roller 2, the rear end of the card in the bin can be supported on the supporting boss 3, so that the rear end of the card in the bin cannot be leaned back to be abutted on the bottom wall of the card accommodating cavity 1, and the projection of the gravity center of the card in the bin along the vertical direction is located on one side, close to the card inlet opening 22, of the first driving roller 2, so that the leaning action of the card in the bin is avoided, and the front end of the card in the bin can be abutted on the side wall of the front end of the card accommodating cavity 1.

With continued reference to fig. 8-18, the front end of the card in the bin is abutted against the side wall of the front end of the card accommodating cavity 1, and still possibly cannot fall normally due to factors such as burrs of the card 100, so that in order to solve the problem, the connecting line between the upper edge of the card inlet 11 and the high point of the first driving roller 2 is lower than the upper surface of the supporting boss 3, so that after the conveyed card passes through the card inlet to finish conveying, the rear end of the card in the bin positioned in Rong Kaqiang 1 is abutted against the supporting boss 3 and cannot contact with the first driving roller 2, and since the supporting boss 3 is far away from the card inlet 11 relative to the first driving roller 2, a larger moment can be provided for the card in the bin, so that the front end of the card in the bin smoothly slides from the side wall of the card accommodating cavity 1 to the card inlet, the card outlet action of the card conveying equipment is continuous, and card outlet failure is avoided.

With continued reference to fig. 8-18, when the end of the card 100 away from the supporting boss 3 abuts against the bottom wall of the card accommodating cavity 1, that is, when the front end of the card 100 abuts against the bottom wall of the card accommodating cavity 1, if the rear end of the supporting boss 3 still abuts against the supporting boss 3 and is spaced from the first driving roller 2, the first driving roller 2 cannot provide driving force for the card 100, so that the card 100 abuts against the first driving roller 2 and the card 100 contacts with or is spaced from the supporting boss 3. In addition, the first driving roller 2 can also play the effect of driving the card 100 to incline forward, when the card in the bin can not contact the side wall of the card accommodating cavity 1 due to backward leaning, the middle section of the card in the bin can contact the first driving roller 2, the first driving roller 2 can provide a certain driving force for forward tilting of the card in the bin, and when the card in the bin inclines forward under the action of the first driving roller 2, the front end of the card in the bin is abutted to the side wall of the card accommodating cavity 1, and at the moment, the middle section of the card in the bin can be separated from the first driving roller 2 and is arranged at intervals with the first driving roller 2, so that the first driving roller 2 is prevented from obstructing falling of the front end of the card in the bin. When the front end of the card in the bin slides from the side wall of the card accommodating cavity 1 to be abutted against the bottom wall of the card accommodating cavity 1, the middle section of the card in the bin can be in contact with the first driving roller 2 again, at the moment, the card in the bin positioned at the lowest position becomes the next card to be conveyed because the card to be conveyed is conveyed, and the first driving roller 2 can provide driving force towards the front end for the new card to be conveyed.

Specifically, when the rear end of the transported card is located between the first driving roller 2 and the supporting boss 3, the card in the hopper is supported by the transported card and the front end side wall of the card accommodating chamber 1. When the rear end of the card to be conveyed is positioned between the card inlet 11 and the first driving roller 2, the card in the bin is supported by the card to be conveyed and the supporting boss 3 and is arranged at intervals with the first driving roller 2, and the upper surface of the card in the bin is always higher than the upper eave of the card inlet 11. After the transported card passes through the card inlet 11 and is transported out of the card accommodating cavity 1, the card in the bin is supported by the bottom wall of the card accommodating cavity 1 and the first driving roller 2, and the rear end of the card in the bin is contacted with or arranged at intervals from the supporting boss 3.

The state of the transported card and the card in the hopper in the above process will be described in detail with reference to fig. 8 to 18:

as shown in fig. 8 to 10, the transported card is located at the first transport position, the front end of the transported card just contacts the second driving roller 5 and is supported by the first driving roller 2, the rear end is spaced from the supporting boss 3, the card in the bin is located at the first storage position, the card in the bin is supported on the transported card and the front end side wall of the card accommodating cavity 1, the upper surface of the card in the bin is always higher than the upper eave of the card inlet 11, and the rear end of the card in the bin is spaced from the supporting boss 3.

As shown in fig. 11 to 14, the transported card is located at the second transport position, the transported card is supported by the second drive roller 5 and the first drive roller 2, the rear end of the transported card is about to separate from the first drive roller 2, the card in the bin is located at the second storage position, at this time, since the projection of the gravity center of the card in the bin along the vertical direction can separate from the transported card, a certain backward tilting occurs, the rear end of the card in the bin is supported on the supporting boss 3, the backward tilting cannot be continued, and the card in the bin is supported on the transported card and is spaced from the first drive roller 2, and the upper surface of the card in the bin is always higher than the upper eave of the card inlet 11.

As shown in fig. 15 to 16, the card to be transported is located at the third transport position, at this time, the rear end of the card to be transported is located between the card inlet 11 and the second driving roller 5, the card in the bin is located at the third storage position, at this time, the rear end of the card in the bin is still supported on the supporting boss 3 and is spaced from the first driving roller 2, the card in the bin is supported on the card to be transported, the height of the front end of the card in the bin gradually decreases due to the gradual decrease of the height of the rear end of the card to be transported, and in addition, the front end of the card in the bin is supported on the supporting boss 3, and can normally fall under the action of gravity to contact with the side wall of the front end of the card accommodating cavity 1, so as to avoid the back leaning of the card in the bin, but the upper surface of the front end of the card in the bin is always higher than the upper eave of the card inlet 11.

As shown in fig. 17 to 18, the transported card is located at the fourth transport position, that is, the transport completion position, where the rear end of the transported card is located outside the card accommodating chamber 1 and in the card inlet 11, where the transported card is completely out of contact with the card in the card hopper, the card in the card hopper is located at the fourth storage position, where the front end of the card hopper has fallen from the side wall of the card accommodating chamber 1 against frictional resistance and is supported on the bottom wall of the card accommodating chamber 1, the middle section is supported on the first driving roller 2, the rear end is spaced from the supporting boss 3, and the upper surface of the card in the card hopper is lower than the upper edge of the card inlet 11, where the card in the card hopper is about to become the next transported card, and the process as in fig. 8 to 10 is repeated.

With continued reference to fig. 8-18, the card conveying apparatus further includes a card pressing roller 4 disposed in the Rong Kaqiang 1, where the card pressing roller 4 is configured to press the card 100 against the first driving roller 2 in a vertical direction, so as to increase a sliding friction between the first driving roller 2 and the card 100, so that the first driving roller 2 can provide a sufficient driving force for the card 100.

In the process shown in fig. 15 to 18, in order to enable the front end of the card in the bin abutting against the side wall of the card accommodating cavity 1 to smoothly fall into the card inlet 11, the front end of the card in the bin can be enabled to fall from the side wall of the card accommodating cavity 1 by other structures besides the above structure, for example, by acting the card pressing roller 4 on the front end of the card in the bin. With reference to fig. 8-18, the projection of the center of the card pressing roller 4 along the vertical direction is located between the card inlet 11 and the center of the first driving roller 2, so that the first driving roller 2 and the card pressing roller 4 can provide a moment for the card 100 along the counterclockwise direction in the drawing, so that the front end of the card 100 can smoothly fall. It should be noted, however, that this moment is not excessive, which may cause the card 100 to buckle, and in order to avoid this problem, a smaller weight of the pinch roller 4 may be used, or the projection of the center of gravity of the pinch roller 4 in the vertical direction may be as close to the first driving roller 2 as possible, for example, in this embodiment, the projection of the center of gravity of the pinch roller 4 in the vertical direction falls on the first driving roller 2.

With continued reference to fig. 8-18, the center of the first driving roller 2 is located between the projection of the center of gravity of the card 100 in the vertical direction and the supporting boss 3, that is, the center of gravity of the card 100 is located between the first driving roller 2 and the second driving roller 5, so that the card 100 is further prevented from tilting backward, and the front end of the card 100 can be supported by the side wall of the card accommodating cavity 1; in addition, after the front end of the card in the bin contacts the side wall of the card accommodating cavity 1, the front end of the card in the bin can fall off from the side wall of the card accommodating cavity 1 through the gravity of the card in the bin.

With continued reference to fig. 8-18, the high point of the second drive roller 5 is located above the bottom wall of the card accommodating cavity 1, so that when the transported card is located at the first transport position, that is, the position shown in fig. 8-10, the front end of the transported card is lifted slowly, and the rear end of the transported card falls slowly, so that the rear end of the card in the bin falls slowly on the supporting boss 3, the falling speed of the rear end of the card in the bin is prevented from being too fast, and the card in the bin is caused to move towards the rear end continuously under the action of inertia, and the center of gravity of the card in the bin is caused to move towards the rear end.

With continued reference to fig. 8-18, the support ledge 3 should have a height such that the card in the bin can be supported on the support ledge 3 as early as possible after the transported card is separated from the support ledge 3, so as to avoid further tilting of the card in the bin. In this embodiment, the height of the supporting boss 3 is not lower than the thickness of one card 100, on one hand, it can make the card in the bin abut against the supporting boss 3 as soon as possible, avoiding backward tilting, on the other hand, when the card in the bin abuts against the supporting boss 3, since the transported card is often already contacted with the second driving roller 5, the second driving roller 5 can provide enough driving force for the transported card, at this time, the pressure given by the card in the bin to the transported card increases the friction resistance between the card in the bin and the transported card, and hinders the movement of the transported card, and after the card in the bin abuts against the supporting boss 3, the pressure applied to the transported card is reduced, thereby reducing the friction resistance.
