DETAILED DESCRIPTION

[0042] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0043] like Figure 1-11 As shown, a feces tube labeling machine comprises a machine body 1, a conveyor belt 2 and a plurality of connecting seats 3 which are arranged in a linear array along the conveyor belt 2 and are hinged to each other;

[0044] A special-shaped feces pipe 9, on which a convex strip 92 is provided;

[0045] The fixing unit disposed on the connecting seat 3 and used to keep the special-shaped feces tube 9 in a vertical state includes pneumatic fingers 8 disposed opposite to each other. The pneumatic fingers 8 include a rotatably disposed base 81 and a finger joint 87 located at the end of the base 81 and provided with a ligament 83. The pneumatic fingers 8 have an expanded state in which the special-shaped feces tube 9 is no longer clamped.

[0046] The number of the knuckles 87 is not less than two and they are sequentially deployed from farthest to closest to the base 81;

[0047] A labeling unit, which includes an inclined block 17 for guiding the special-shaped feces pipe 9 into the labeling station;

[0048] And located under the labeling station, the pneumatic fingers 8 are spread out and staggered with the special-shaped feces pipe 9.

[0049] Specifically, the machine body 1 is provided with a pipe inlet 11, and the machine body 1 is provided with a pipe outlet 13 at a position corresponding to the labeling station. The conveyor belt 2 is provided with a driving wheel 4, which drives a plurality of connecting seats 3 to transmit, and a balancing plate 7 is rotatably provided on the connecting seats 3, and the fixing unit is located on the balancing plate 7. Since the bottom weight of the balancing plate 7 is relatively large, the balancing plate 7 drives the fixing unit to remain in a vertical state under the influence of gravity.

[0050] Furthermore, the machine body 1 is provided with an operation panel 12 with a preset program, the operation panel 12 includes a scanning unit for reading a barcode or a two-dimensional code, and the machine body 1 is provided with a printing program for printing the read information on a label.

[0051] Furthermore, the special-shaped feces tube 9 enters the body 1 along the tube inlet 11, and the pneumatic finger 8 is in a retracted state. In this state, multiple knuckles 87 in the pneumatic finger 8 are close to each other and enclosed to form a clamping space for the special-shaped feces tube 9 to be inserted. Since the pneumatic finger 8 has multiple knuckles 87 and is connected to each other by ligaments 83, the knuckles 87 can be adaptively adjusted according to the outer wall shape of the special-shaped feces tube 9, and can autonomously adapt to special-shaped feces tubes 9 of different shapes. The conveyor belt 2 drives the connecting seat 3 and the fixing unit to approach the labeling unit. Since there is an inclined guide surface between the conveyor belt 2 and the labeling unit, and the inclination angle is consistent with the inclination angle of the inclined block 17, the inclined block 17 is made of flexible rubber material, and the special-shaped feces tube 9 will be driven by the conveyor belt 2 and slide along the inclined surface of the inclined block 17. The top end of the special-shaped feces tube 9 will push the inclined block 17 and cause the inclined block 17 to deform slightly. At this time, the bottom end of the inclined block 17 clamps the top end of the special-shaped feces tube 9, so that the special-shaped feces tube 9 enters the labeling station. An image detection unit or a pressure sensing unit can be set at the labeling station. After the special-shaped feces tube 9 is in place, the pneumatic finger 8 is driven to expand. The pneumatic finger 8 can be supplied with air to the knuckles 87 located farther away to expand them, thereby expanding the knuckles 87 in order from far to near, extending the expansion time, and preventing the special-shaped feces tube 9 from being loosened when it is not fully in place, which may cause loosening or falling at the labeling station, and ensuring that the special-shaped feces tube 9 is maintained in a vertical state. After fully expanded, the pneumatic finger 8 is driven to approach the balance plate 7 by the setting of the electric telescopic rod or cylinder. At this time, the pneumatic finger 8 and the special-shaped feces tube 9 are staggered to avoid interference with subsequent labeling. Then the special-shaped feces tube 9 is labeled. After the labeling is completed, the built-in program of the body 1 detects that the special-shaped feces tube 9 has completed labeling, and the electric telescopic rod or cylinder is started to push the special-shaped feces tube 9, so that the special-shaped feces tube 9 is transferred out from the outlet 13.

[0052] The user scans the code through the operation panel 12, prints the corresponding information on the label, then drives the conveyor belt 2 to guide the special-shaped feces tube 9 to the labeling station, sticks the corresponding label to the outside of the special-shaped feces tube 9, and then takes the special-shaped feces tube 9 through the outlet 13.

[0053] In the above technology, the finger joint 87 can be adaptively adjusted according to the outer wall shape of the special-shaped feces tube 9, and can autonomously adapt to the special-shaped feces tube 9 of different shapes, so as to avoid the special-shaped feces tube 9 being loosened when it is not fully in place, and the problem of loosening or falling at the labeling station may occur, thereby ensuring that the special-shaped feces tube 9 remains in a vertical state.

[0054] As an embodiment further provided by the present invention, the knuckle 87 includes a distal knuckle and a proximal knuckle, and further includes:

[0055] A first air bag 86 disposed between the distal knuckle and the proximal knuckle;

[0056] A second air bag 85 disposed between the proximal knuckle and the base 81;

[0057] A third airbag 84 is disposed on the base 81 and is used to control the deflection of the base 81 .

[0058] Specifically, the third airbag 84 is arranged between the balance board 7 and the base 81, and the first airbag 86, the second airbag 85 and the third airbag 84 are interconnected. In the process of plugging the special-shaped feces tube 9, the gas between the three airbags flows to each other, thereby driving the knuckles 87 to flex and contract, and the adaptive adjustment of the pneumatic fingers 8 is achieved through the deformation performance of the airbags. The airbags are all located on the side facing the special-shaped feces tube 9, and the ligament 83 is located on the other side opposite thereto, so that the airbags can squeeze the special-shaped feces tube 9 through their own expansion, thereby achieving a better anti-slip effect.

[0059] As another embodiment further provided by the present invention, it also includes an elastic airbag 31 for supplying air to the pneumatic finger 8, on which a connecting pipe 821 connected to the first airbag 86 is provided, and the connecting seat 3 is located under the labeling station, and the elastic airbag 31 is compressed.

[0060] Specifically, a fixed cam 5 is fixedly arranged in the body 1. When the connecting seat 3 moves close to the fixed cam 5, the elastic airbag 31 is squeezed and contracted by the fixed cam 5. After the elastic airbag 31 leaves the fixed cam 5, it automatically rebounds and sucks the air in the airbag. When the elastic airbag 31 contracts, the internal air is squeezed into the connecting pipe 821, and then enters the first airbag 86 through the connecting pipe 821. An air cavity 88 is arranged between the first airbag 86 and the second airbag 85, and between the second airbag 85 and the third airbag 84, so that the air enters the first airbag 86 and then enters the second airbag 85 and the third airbag in turn. After the first airbag 86 expands, it drives the distal knuckle to deflect in the direction away from the special-shaped feces tube 9, and then drives the proximal knuckle to deflect. Through two deflections, the knuckle 87 will not interfere with the special-shaped feces tube 9 entering the labeling station, and the overall range of motion of the pneumatic finger 8 can be reduced, thereby reducing the space occupied by the fixed unit, making the overall device more streamlined.

[0061] As another embodiment further provided by the present invention, it also includes a longitudinal slide rail 72 for the pneumatic finger 8 to slide;

[0062] A movable rotating rod 74 for driving the pneumatic finger 8 to be in close contact with the connecting seat 3;

[0063] An elastic ball 76 for locking the base 81 at a predetermined angle;

[0064] The base 81 deflects so that the elastic ball 76 is offset from the base 81 .

[0065] Specifically, it also includes a movable rotating rod 74 rotatably arranged on the balance board 7, the first end of the movable rotating rod 74 is slidably arranged on the balance board 7, and the balance board 7 is also provided with a transverse slide rail 71 to control the moving path of the first end, and the second end of the movable rotating rod 74 is rotatably connected to the base 81, and the base 81 is slidably arranged on the longitudinal slide rail 72. The two ends of the first spring 75 are respectively connected between the balance board 7 and the base 81. In the default state, the base 81 is located at the end of the longitudinal slide rail 72 away from the balance board 7. At this time, the first spring 75 is in a stretched and force-storing state, and the elastic ball 76 is fixedly arranged on the movable rotating rod 74. At this time, the elastic ball 76 extends out and is stuck between the movable rotating rod 74 and the base 81, so that the movable rotating rod 74 cannot rotate and remains at the current angle, so that the positions of the movable rotating rod 74 and the base 81 are locked. When the base 81 is deflected, the base 81 will squeeze the elastic ball 76, causing the elastic ball 76 to retract into the movable rotating rod 74 and staggered with the base 81. At this time, the movable rotating rod 74 is unlocked, and the stored force of the first spring 75 is released and pulls the base 81 toward the balance board 7, driving the pneumatic finger 8 as a whole to be staggered with the special-shaped feces tube 9 to avoid interfering with the labeling of the special-shaped feces tube 9. The movement of the base 81 will only be triggered after the base 81 is deflected, which can ensure that the pneumatic finger 8 no longer clamps the special-shaped feces tube 9 at this time.

[0066] As another embodiment further provided by the present invention, it also includes a sliding seat 73 disposed on the connecting seat 3 , and the protruding strip 92 is slidably inserted into the sliding seat 73 .

[0067] Specifically, after the special-shaped feces tube 9 enters through the pipe inlet 11, it is plugged along the clamping space formed by the pneumatic fingers 8, and the convex strip 92 abuts against the slide 73. Under the gravity of the special-shaped feces tube 9 itself, it slides down along the slide 73 and drives the pneumatic fingers 8 to move, so that the base 81 slides along the longitudinal slide rail 72 toward the end away from the balance plate 7. During the deflection of the movable rotating rod 74, the elastic ball 76 loses the obstruction of the base 81 and naturally extends outward. The elastic ball 76 is stuck between the base 81 and the movable rotating rod 74, locking the angle between the movable rotating rod 74 and the base 81. At the same time, the first spring 75 stretches and starts to accumulate force. In addition, the cooperation between the convex strip 92 and the slide 73 can keep the special-shaped feces tube 9 in a vertical state at all times, which is conducive to the subsequent labeling process.

[0068] As another embodiment further provided by the present invention, it also includes a fixing frame 14 on which a labeling roller 16 abutting against the special-shaped feces pipe 9 is arranged.

[0069] Specifically, it also includes a labeling plate 18 for conveying label paper, and a shovel plate facing the side of the labeling roller 16 is provided at the end of the labeling plate 18, and a roller 181 for keeping a distance from the special-shaped feces tube 9 is provided on the shovel plate, and a limit roller 183 and a winding roller 184 for collecting label paper are also provided. The rollers 181 are relatively rotatably arranged on the shovel plate, and a second spring 182 is provided between the rollers 181, so that the two rollers 181 maintain a predetermined angle and extend out of the shovel plate. When the special-shaped feces tube 9 enters the labeling station along the inclined block 17, the side wall of the special-shaped feces tube 9 squeezes the roller 181, driving the labeling plate 18 to deflect, and under the pressure of the roller 181, a certain distance is maintained between the shovel plate and the outer wall of the special-shaped feces tube 9, and the distance is used for label pasting. The labeling roller 16 is rotatably arranged on the pressing rod 15, and a torsion spring 151 is arranged on the pressing rod 15 so that the pressing rod 15 drives the labeling roller 16 to be closely attached to the side wall of the special-shaped feces tube 9. Since the labeling roller 16 is a rubber product, static electricity is generated during the contact between the labeling roller 16 and the plastic outer wall of the special-shaped feces tube 9. The static electricity adsorbs the label to the side of the labeling roller 16, and then the label is attached to the surface of the special-shaped feces tube 9 through the rotation of the labeling roller 16. The settings of the labeling roller 16 and the roller 181 can adapt to special-shaped feces tubes 9 of different shapes.

[0070] As another embodiment further provided by the present invention, a driving motor 171 for driving the special-shaped feces pipe 9 is disposed on the fixing frame 14 , and the labeling roller 16 and the special-shaped feces pipe 9 keep synchronous movement.

[0071] Specifically, a cylinder is rotatably arranged at the rotating shaft of the pressing rod 15, and the end of the cylinder is connected to the output shaft of the driving motor 171 through the first transmission belt 172, and the cylinder is also connected to the labeling roller 16 through the second transmission belt 161. The driving motor 171 is used to drive the inclined block 17, and the special-shaped feces tube 9 slides along the inclined surface of the inclined block 17 and is clamped by the inclined block 17. Then, the driving motor 171 is started to make the special-shaped feces tube 9 start to rotate. At this time, the labeling roller 16 rotates synchronously and the direction is consistent with the special-shaped feces tube 9, so that Figure 7 As shown, the special-shaped feces tube 9 and the labeling roller 16 both rotate clockwise. Since the contact parts of the labeling roller 16 and the special-shaped feces tube 9 rotate in opposite directions, the labeling roller 16 will generate a tangential force on the label, making the label adsorption more firmly.

[0072] As another embodiment further provided by the present invention, it also includes a swivel seat 19 rotatably arranged on the fixed frame 14 and used for rotating the special-shaped feces pipe 9, a rotatable member 196 for pushing the special-shaped feces pipe 9 is rotatably arranged on the fixed frame 14, and a triggering station for triggering the swivel member 196 exists in the movable stroke of the swivel seat 19.

[0073] Specifically, a protrusion 191 is provided on the rotating seat 19, a shaped wheel 192 periodically meshing with the protrusion 191 is rotatably provided on the fixed frame 14, a first bevel gear 193 is fixedly provided on the shaped wheel 192, a second bevel gear 194 meshing with the first bevel gear 193 is rotatably provided on the fixed frame 14, and the first bevel gear 193 and the second bevel gear 194 are connected through a third transmission belt 195. When the special-shaped feces tube 9 rotates, it drives the rotating seat 19 to rotate synchronously, so that the protrusion 191 rotates one circle and then drives the special-shaped wheel 192 to deflect, and the first bevel gear 193 is driven to rotate by the special-shaped wheel 192, and the second bevel gear 194 is driven to rotate by the first bevel gear 193, thereby realizing the rotation of the rotating member 196, which is the triggering position of the rotating seat 19, and the rotating member 196 rotates and pushes the special-shaped feces tube 9, so that the special-shaped feces tube 9 is pushed out after the labeling is completed, and rolls into the outlet 13 along the slope 6 fixedly arranged in the body 1.

[0074] As another embodiment further provided by the present invention, the special-shaped feces pipe 9 is a polyhedral columnar structure, and a filter plate 91 for separating feces liquid is arranged inside the special-shaped feces pipe 9.

[0075] Specifically, the polyhedral column structure can make the special-shaped feces tube 9 not easy to roll, and can better maintain the vertical direction during the inspection process, making it more convenient to stack. The filter plate 91 can separate the feces inside into feces liquid, and the liquid in the feces can be extracted without filtering and screening operations.

[0076] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
