[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Reference Figure 1-8 An embodiment of the present invention discloses a self-service stamping robot page turning device, which is used to automatically turn over the paper to be stamped, so as to solve the inconvenience of manually turning over the odd and even pages when stamping. Specifically, the turning device of the present invention includes a frame 3 having a paper feed channel 1 and a paper discharge channel 2;

[0035] and a turning mechanism 4 disposed in the frame 3, the turning mechanism 4 being located between the paper feed channel 1 and the paper discharge channel 2, and a vertical paper path 5 located above the turning mechanism 4 being further disposed above the frame 3;

[0036] Reference Figure 6 , wherein, when the turning mechanism 4 is located at a first predetermined angle, the paper enters along the paper feed channel 1 and moves out along the paper output channel 2;

[0037] Reference Figure 7 、 8 When the turning mechanism 4 is at the second predetermined angle, the paper enters the turning mechanism 4 along the paper feed channel 1, and is changed in direction by the turning mechanism 4 before entering the vertical paper path 5; after the turning mechanism 4 is turned to the third predetermined angle, the paper in the vertical paper path 5 enters the turning mechanism 4, and is changed in direction by the turning mechanism 4 before moving out along the paper discharge channel 2.

[0038] It should be pointed out that, when the two ends of the flipping mechanism 4 in this embodiment are respectively facing the paper feed channel 1 and the paper discharge channel 2, the flipping mechanism 4 is located at a first predetermined angle. In this embodiment, the first predetermined angle is 0°, the second predetermined angle is 90° clockwise rotation, and the third predetermined angle is -90° counterclockwise rotation. The specific working principle will be described in detail later and will not be elaborated here.

[0039] Reference Figure 2 、 3 5. In some embodiments, the present invention has two paper feed channels 1, the tail ends of the two paper feed channels 1 are connected to the paper feed front end of the paper discharge channel 2, and a first paper guide 11 is provided at the junction of the paper feed channel 1 and the paper discharge channel 2. The function of the first paper guide 11 is to facilitate the delivery of paper to the interior of the frame 3. At the same time, the present invention adopts the design of two paper feed channels 1 to achieve paper loading on both sides to optimize the convenience of operation. Furthermore, in this embodiment, the two paper feed channels 1 are both arranged on one side of the frame 3 and stacked up and down.

[0040] Reference Figure 3 On the basis of the above embodiment, an upper baffle 31, an upper guide plate 32 and a lower guide plate 33 are fixedly installed on the side of the frame 3, and a lower baffle 34 is fixed to the bottom of the upper guide plate 32. The lower baffle 34 is an L-shaped structure, and two paper feed channels 1 are formed between the upper baffle 31 and the upper guide plate 32, and between the lower baffle 34 and the lower guide plate 33. Furthermore, in this embodiment, a first sensor 37 can be provided on the upper baffle 31 and the lower baffle 34 to detect paper feeding. The first sensor 37 is used to be electrically connected to an external control unit so that when paper is filled in the paper feed channel 1, the control unit can drive the first paper guide 11 to feed paper. Of course, the control unit in this embodiment can be set as a PLC, and preferably the first sensor 37 can be set as a photoelectric switch. In addition, each sensor described below in the present utility model can be set as a photoelectric switch, which will not be described in detail later.

[0041] Reference Figure 3Furthermore, the paper discharge channel 2 in the present invention is composed of a paper discharge guide 21 and a paper discharge pressure plate 22 stacked in the frame 3, and a second paper guide 23 is also provided between the tail ends of the paper discharge guide 21 and the paper discharge pressure plate 22 along the paper discharge direction. Specifically, one side of the paper discharge guide 21 in the present invention extends to the first paper guide 11 for receiving the conveyed paper, and the paper discharge pressure plate 22 is located on the side of the flipping mechanism 4 to avoid interfering with the rotation action of the flipping mechanism 4. Furthermore, in the present invention, a second sensor 27 is fixedly installed above the paper discharge pressure plate 22, which is used to detect when paper enters the paper discharge channel 2. Of course, the second sensor 27 is also electrically connected to the control unit.

[0042] Reference Figure 3 、 5 In a preferred embodiment, the paper output guide 21 of the present invention has a downwardly recessed avoidance portion 24 in the middle thereof. The avoidance portion 24 is designed to avoid the rotation area of ​​the flipping mechanism 4. At the same time, in order to achieve stable connection of the paper flipped by the flipping mechanism 4, a plurality of notches are separated in the middle of the avoidance portion 24. Two fixing bars 25 are fixedly installed on the paper output guide 21 below the avoidance portion 24. A plurality of translation bars 26 located in the notches are connected between the two fixing bars 25.

[0043] Specifically, the purpose of using multiple translation bars 26 in the present invention is to transport the paper in a straight line, that is, when the flip mechanism 4 is at the first predetermined angle, the flip mechanism 4 is placed horizontally. Therefore, in order to ensure that the paper can pass smoothly from the above-mentioned avoidance portion 24, the present invention uses multiple translation bars 26 for support to achieve paper transportation in this state.

[0044] Reference Figure 3 、 5 Furthermore, in this embodiment, the turning mechanism 4 includes a first curved plate 41 and a second curved plate 42 that are stacked, wherein the second curved plate 42 is located below the first curved plate 41. The first curved plate 41 and the second curved plate 42 are connected at both ends and rotatably connected to the inner side of the frame 3. A turning paper path is formed between the first curved plate 41 and the second curved plate 42.

[0045] Reference Figure 1 , wherein a driving member 43 for driving the first arc plate 41 and the second arc plate 42 to rotate is also fixedly installed on the outside of the frame 3. Preferably, the driving member 43 in this embodiment is a servo motor, which is installed on the outside of the frame 3 by fasteners such as bolts. Specifically, the shaft end of the motor is connected and fixed to one connecting end of the first arc plate 41 and the second arc plate 42 to drive the first arc plate 41 and the second arc plate to rotate as a whole.

[0046] Reference Figure 2 Furthermore, in the present invention, a connecting plate is fixedly installed on the side of the frame 3, and the connecting plate is rotatably connected to the first arc plate 41 and one connecting end of the second arc plate. An arc-shaped through-hole is also opened on the outer side of the connecting plate to facilitate observation of the rotation angle of the inner flip mechanism 4 during operation.

[0047] Reference Figure 6-8 On the basis of the above embodiment, the transverse cross-sections of the first arc plate 41 and the second arc plate 42 in the present invention are both U-shaped structures, and a U-shaped bending structure design is adopted to facilitate the guidance of paper. A plurality of avoidance grooves 44 are further provided on both end sides of the first arc plate 41 and the second arc plate 42. The avoidance grooves 44 are staggered and avoid the translation strip 26. The design of the avoidance grooves 44 can provide an avoidance position when the second arc plate 42 rotates to the inside of the avoidance portion 24, so that the second arc plate 42 can sink into the avoidance portion 24, so that the paper can be smoothly and stably transported along the translation strip 26 toward one side of the paper output channel 2.

[0048] Reference Figure 3 、 5 In addition, in order to further ensure the paper conveying effect, in this embodiment, a mounting plate 35 is fixedly installed on the inner side of the frame 3, and a plurality of anti-jamming claws 36 are provided on the side of the mounting plate 35. The plurality of anti-jamming claws 36 are staggered and plugged into the avoidance groove 44, and a placement opening for avoiding the anti-jamming claws 36 is opened on the end surface of the paper discharge pressure plate 22.

[0049] Specifically, the present invention takes into account that during the actual conveying process, when the paper is conveyed outward along the flipping paper path of the first arc plate 41 and the second arc plate 42, if there is no blocking limit on the upper side, the paper may bend upward and cause paper jam. Therefore, the present invention adopts a design of multiple anti-jamming claws 36. When the entire flipping mechanism 4 is at the third predetermined angle, the multiple anti-jamming claws 36 are inserted and staggered with the avoidance groove 44 on the first arc plate 41, so that the upper side of the paper can be guided and limited to improve its transfer stability and solve the paper jam problem.

[0050] Reference Figure 1 、 25. In some embodiments, the vertical paper path 5 in the present invention is composed of a rectangular frame vertically connected to the frame 3. The inner opening of the rectangular frame forms the vertical paper path 5. A third paper guide 51 is also installed in the rectangular frame. Of course, in the present invention, a third sensor 53 can also be provided on the rectangular frame. The third sensor 53 is used to detect the position of the paper entering the vertical paper path 5. The third sensor 53 is electrically connected to the control unit.

[0051] Among them, both sides of the bottom of the rectangular frame are provided with guiding claws 52 that are staggered and plugged into the avoidance grooves 44. The purpose of providing the guiding claws 52 is also to achieve connection with the first arc plate 41 and the second arc plate 42 to ensure that the paper can be stably transferred toward the inner side of the vertical paper path 5. Specifically, when the flipping mechanism 4 is at the second predetermined angle and the second predetermined angle, the avoidance grooves 44 at the ends of the first arc plate 41 and the second arc plate 42 are plugged and staggered with the guiding claws 52 on both sides of the bottom of the rectangular frame to form a continuous conveying channel, thereby avoiding paper jams.

[0052] Reference Figure 1 、 2 5. It should be noted that, in the present invention, the first paper guide 11, the second paper guide 23, and the third paper guide 51 each include two opposing pressure rollers. Specifically, the two pressure rollers of the first paper guide 11 and the second paper guide 23 are rotatably connected to the interior of the frame 3, and the two pressure rollers of the third paper guide 51 are rotatably connected to the rectangular frame. The two pressure rollers are used to squeeze and drive the paper to move when rotating;

[0053] Among them, two motors 6 are fixedly installed on the inner side of the frame 3, one of the motors 6 is connected to a pressure roller of the second paper guide 23, and the other motor 6 is connected to a pressure roller of the first paper guide 11, and the first paper guide 11 is connected to the third paper guide 51 through a transmission structure 61.

[0054] Reference Figure 1 Preferably, the transmission structure 61 described in this embodiment is a pulley and a belt. Specifically, in the present invention, a pressure roller end of the first paper guide 11 and a pressure roller end of the third paper guide 51 are both fixed with pulleys, and the two pulleys are driven by belts. The use of this transmission structure design can reduce the demand for driving parts and ensure the consistency of the actions of the two.

[0055] When working, when a front stamp is required:

[0056] Reference Figure 6At this time, the turning mechanism 4 is at a first predetermined angle, that is, the two first curved plates 41 and the second curved plate 42 are facing the paper feed channel 1 and the paper discharge channel 2 respectively, and the whole is in a horizontal 0° position. At this time, since the bottom of the second curved plate 42 does not contact the paper discharge guide 21, when the paper enters along the paper feed channel 1, it is driven forward by the first paper guide 11 and then carried by the multiple translation bars 26. It can be discharged outward along the paper discharge channel 2 and transferred to the stamp machine at the rear end;

[0057] When stamping is required:

[0058] Reference Figure 7 The driving member 43 drives the first curved plate 41 and the second curved plate 42 to rotate clockwise by 90 degrees. At this time, the avoidance groove 44 of the second curved plate 42 is inserted and staggered with the translation bar 26 to form a continuous conveying channel. At this time, the paper enters between the first curved plate 41 and the second curved plate 42 along the paper feed channel 1, and enters the interior of the vertical paper channel 5 along the turning paper path between the first curved plate 41 and the second curved plate 42. After the paper is completely separated from the first curved plate 41 and the second curved plate 42, the paper is temporarily stored in its position by the third paper guide 51.

[0059] Reference Figure 8 Furthermore, when the paper completely enters the vertical paper path 5, the first arc plate 41 and the second arc plate 42 first rotate counterclockwise one hundred and eighty degrees to a third predetermined angle. Similarly, the avoidance groove 44 and the translation bar 26 are inserted and staggered to form a continuous conveying channel. The third paper guide 51 conveys the paper downward, and the paper enters the flipping paper path and is discharged after being conveyed to the paper output channel 2, completing the flipping operation of the paper, and realizing the purpose of automatically flipping the odd and even pages of the stamped side.

[0060] In summary, the utility model adopts the design of a built-in flipping mechanism 4, which can realize straight-line transportation of the front side of the paper when it is not in action to meet the stamping requirements of the front side of the paper. When the paper needs to be turned over for stamping, the flipping mechanism 4 guides the paper to the vertical paper path 5, and then flips it through the flipping mechanism 4 to realize the flipping operation. In this way, the purpose of automatic flipping of the odd and even pages of the stamping surface can be achieved. The overall simple design optimizes the adjustment efficiency of the paper pages during the stamping operation.

[0061] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
