Description

Technical Field

[0001] This utility model relates to the field of card sorting technology, and in particular to a card sorting machine and its feeding device. Background Technology

[0002] When a card sorting machine is being loaded, a transfer device typically moves the cards from the card storage compartment to the conveyor belt of the card sorting machine. To achieve this process, the transfer device usually includes a guide rail and a gripping component. The two ends of the guide rail are located near the conveyor belt and the card storage compartment, respectively. After the gripping component grabs a card from the card storage compartment, it moves along the guide rail to the conveyor belt and places the card on the conveyor belt.

[0003] However, such a structure not only takes up a lot of space for the guide rails, but also the fact that each gripping component performs a single action of gripping, transferring and placing simultaneously, resulting in a slow loading speed. Utility Model Content

[0040] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0041] Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0042] Please refer to Figure 1 and Figure 2The feeding device of a card sorting machine according to an embodiment of the present invention includes: a card storage mechanism 1 and a transfer mechanism 2.

[0043] The card storage mechanism 1 includes a card storage compartment 11, which has an opening 111 at the top and is used to stack and store cards inside.

[0044] Please refer to Figure 3 The transfer mechanism 2 is located on one side of the card storage mechanism 1. The transfer mechanism 2 includes a first base 21, a first drive device 22, a rotating shaft 23, and multiple gripping mechanisms 24. The rotating shaft 23 is rotatably mounted on the first base 21, and the multiple gripping mechanisms 24 are arranged around the rotating shaft 23. The first drive device 22 drives the rotating shaft 23 to rotate. The rotation of the rotating shaft 23 enables each gripping mechanism 24 to move alternately to the gripping position 241 and the placement position 242. The gripping position 241 and the placement position 242 are partially circumferential to the rotating shaft 23. The gripping mechanism 24 grips the card in the card storage compartment 11 at the gripping position 241 and places the card at the placement position 242.

[0045] The gripping mechanism 24 of the transfer mechanism 2 grips a card in the card storage compartment 11 at gripping position 241. The first driving device 22 drives the rotating shaft 23 to rotate, causing the gripping mechanism 24 to move to the placement position 242. The gripping mechanism places the card on the conveying mechanism 3 of the card sorting machine. At the same time, other gripping mechanisms 24 are located at gripping position 241 and grip the card in the card storage compartment 11. Then, the first driving device drives the rotating shaft 23 to rotate, and the gripping mechanism 24 at the placement position 242 leaves the placement position 242, while the gripping mechanism 24 at the gripping position 241 moves to the placement position 242 and places the card on the conveying mechanism 3 of the card sorting machine. At the same time, the gripping mechanism 24 that left the placement position 242 moves to the gripping position 241, or other gripping mechanisms 24 move to the gripping position 241 and grip the card in the card storage compartment 11. This allows different gripping mechanisms 24 on the rotating shaft 23 to grip and place cards, with each gripping mechanism 24 performing different actions, thereby accelerating the feeding speed.

[0046] The structure of the gripping mechanism 24 driven by the rotation of the rotating shaft 23 is relatively compact and does not require much space, thus saving space resources.

[0047] In some embodiments, please refer to Figure 5 The card storage mechanism 1 includes a second base 12 and a turntable 13. The turntable 13 is rotatably mounted on the second base 12. The card storage compartment 11 is mounted on the turntable 13. The card storage compartment 11 includes a first sub-compartment 11A and a second sub-compartment 11B. Both the first sub-compartment 11A and the second sub-compartment 11B are used to stack and store cards. The rotation of the turntable 13 can rotate at least the first sub-compartment 11A or the second sub-compartment 11B to below the gripping position 241.

[0048] The first sub-compartment 11A and the second sub-compartment 11B have the same structure. One of them will be located below the grab position 241. The card in the first sub-compartment 11A or the second sub-compartment 11B below the grab position 241 will be grabbed by the grabbing mechanism 24, while the card in the other sub-compartment will not be grabbed.

[0049] When the first sub-compartment 11A is below the gripping position 241, the cards in the first sub-compartment 11A will be gripped by the gripping mechanism 24. After all the cards in the first sub-compartment 11A are removed, the turntable 13 rotates, causing the first sub-compartment 11A and the second sub-compartment 11B to move. The second sub-compartment 11B moves below the gripping position 241, and the gripping mechanism 24 continues to grip the cards in the second sub-compartment 11B. At the same time, cards can be loaded into the first sub-compartment 11A, realizing card replenishment without stopping the machine. The transfer mechanism 2 does not need to wait for the card storage compartment 11 below the gripping position 241 to be loaded with cards before it starts working, thus speeding up the feeding speed.

[0050] Please refer to Figure 6 and Figure 7 The card storage mechanism 1 also includes a tray 14 and a third drive device 15. The first sub-compartment 11A and the second sub-compartment 11B are both provided with trays 14. The third drive device 15 is provided on the turntable 13. The third drive device 15 drives the tray 14 to move up and down in the card storage compartment 11. The tray 14 is used to support the cards.

[0051] The third drive device 15 drives the tray 14 to move up and down, thereby causing the cards stacked on the tray 14 to move up and down. When the gripping mechanism 24 grips a card, the stack height of the cards on the tray 14 decreases. To facilitate gripping by the gripping mechanism 24, the third drive device 15 drives the tray 14 to move upward, so that the cards to be gripped remain at the same height. That is, no matter how many cards are gripped, the height of the highest card on the tray 14 remains unchanged. When replenishing cards into the card storage compartment 11, the third drive device 15 drives the tray 14 to move downward.

[0052] Please refer to Figure 6 and Figure 8 The card storage mechanism 1 also includes a bracket 16, a lead screw 17, and a lead screw nut. The bracket 16 is vertically mounted on the turntable 13. The first sub-compartment 11A and the second sub-compartment 11B are mounted on the bracket 16. Each of the first sub-compartment 11A and the second sub-compartment 11B has a channel 112 on its side wall facing the bracket 16. The third drive device 15 is connected to the lead screw 17. The lead screw 17 is vertically mounted and the lead screw nut is sleeved on the lead screw 17. The support plate 14 is connected to the lead screw nut and passes through the channel 112.

[0053] The third drive device 15 drives the lead screw 17 to rotate, and the lead screw nut moves up and down on the lead screw 17, thereby driving the pallet 14 to move up and down. By providing a channel 112 on the side wall of the card storage compartment 11, the pallet 14 can pass through the channel 112 and extend into the inside of the card storage compartment 11. This allows the lead screw 17 to be positioned on one side of the card storage compartment 11, thereby reducing the overall height of the card storage mechanism 1 and facilitating the cooperation between the card storage mechanism 1 and the transfer mechanism 2.

[0054] The card storage mechanism 1 also includes a guide rod 131 and a connecting block 18. The guide rod 131 is vertically arranged on the turntable 13. The support plate 14 is connected to the lead screw nut through the connecting block 18. The connecting block 18 is also sleeved on the guide rod 131 and is slidably connected to the guide rod 131.

[0055] The guide rod 131 and the lead screw 17 are arranged in parallel. During the up-and-down movement, the connecting block 18 is driven up and down by the lead screw nut and its movement path is limited by the guide rod 131. Thus, when the connecting block 18 drives the pallet 14 to move, the movement accuracy of the pallet 14 can be ensured.

[0056] The card storage mechanism 1 also includes a limiting member 161, which is disposed on the bracket 16 and is used to cooperate with the connecting block 18 to limit the movement path of the tray 14.

[0057] In this embodiment, two limiting members 161 are provided at the top and bottom. The limiting members 161 can block part of the connecting block 18, restricting the connecting block 18 from continuing to move, thereby restricting the movement path of the tray 14.

[0058] In some embodiments, please refer to Figure 3 and Figure 4 The rotating shaft 23 is vertically arranged. The transfer mechanism 2 also includes a connector 25 and a second drive device 26. The connector 25 is arranged on the rotating shaft 23, and the second drive device 26 is arranged on the connector 25. The second drive device 26 drives the gripping mechanism 24 to move up and down.

[0059] The rotating shaft 23 is set vertically, so that the gripping mechanism 24 is set around the rotating shaft 23.

[0060] The connector 25 drives the gripping mechanism 24 to move, thereby enabling the gripping mechanism 24 to move between the gripping position 241 and the placement position 242. When the gripping mechanism 24 is in the gripping position 241 or the placement position 242, the second drive device 26 drives the gripping mechanism 24 to move up and down to approach the card to be gripped, or to approach and move to the specific position where the card is placed.

[0061] The transfer mechanism 2 also includes a slide rail 27 and a slider 28. The slide rail 27 is vertically mounted on the connector 25, and the slider 28 is slidably connected to the slide rail 27. The gripping mechanism 24 is also connected to the slider 28.

[0062] The slide rail 27 and slider 28 enable the gripping mechanism 24 to move up and down stably, ensuring the motion accuracy of the gripping mechanism 24.

[0063] The gripping mechanism 24 includes a suction cup 243 and a sensor 244. The second driving device 26 drives the suction cup 243 and the sensor 244 to move up and down. The sensor 244 is electrically connected to the second driving device 26.

[0064] The suction cup 243 can pick up cards and grasp them.

[0065] Sensor 244 detects the distance between suction cup 243 and the card on tray 14, so that the second drive device 26 moves suction cup 243 to the position to grasp the card. Sensor 244 can also detect the distance between suction cup 243 and the conveying mechanism 3 of placement position 242, so that the second drive device 26 moves suction cup 243 to the position to place the card.

[0066] In this embodiment, the first drive device 22 and the third drive device 15 are motors, and the second drive device 26 is a cylinder or a hydraulic cylinder.

[0067] This embodiment also provides a card sorting machine, including the aforementioned feeding device and conveying mechanism 3. The conveying mechanism 3 is used to transport cards, and the cards are sorted during the transport process. The feeding device transports cards to the conveying mechanism 3. In this embodiment, the card storage mechanism 1 and the conveying mechanism 3 are respectively arranged on both sides of the transfer mechanism 2.

[0068] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
