[0028] like Figure 1 The bag unscrambling device of a bag making machine shown in the figure comprises a horizontally arranged mounting frame 1, two parallel conveyor belts 2 arranged on the mounting frame 1, side baffles 3 parallel to the transport direction of the conveyor belts 2 are arranged on both sides of the two conveyor belts 2, and a first bag pushing device and a second bag pushing device for pushing the stack of bags to make the edges of the bags neat;
[0029] like Figure 4 As shown, a lifting door 4 is installed above the mounting frame 1 and can block the bag after it is lowered;
[0030] The second bag pushing device, the first bag pushing device, and the lifting door 4 are arranged in sequence along the conveying direction of the conveyor belt 2 .
[0031] like Figure 1 、 Figure 2 and Figure 4 As shown, the first bag pushing device includes two first push plates 51 arranged parallel to and in parallel with the side baffles 3, and a movable connecting sleeve 52 fixed above the mounting frame 1 is provided between the first push plates 51. The first push plates 51 are suspended above the two conveyor belts 2 through the movable connecting sleeve 52, and the movable connecting sleeve 52 limits the first push plates 51 to only perform linear motion perpendicular to the first push plates 51. It also includes a first transmission mechanism provided between the two first push plates 51 to enable the two first push plates 51 to perform reciprocating linear motion; as shown Figure 1 As shown, preferably, the mounting frames 1 on both sides of the two conveyor belts 2 are provided with a plurality of pairs of symmetrically arranged vertically upward support columns 11, a plurality of cross beams 12 are provided between the symmetrical support columns 11, the movable connecting sleeves 52 are fixed on the cross beams 12, and the support columns 11 and the cross beams 12 play a load-bearing role. Figure 2 and Figure 4As shown, preferably, the movable connecting sleeve shaft 52 includes a second ball sleeve 521 installed with the first push plate 51 below the crossbeam 12, the axis of the second ball sleeve 521 is perpendicular to the first push plate 51, and the first push plate 51 is fixedly connected with a movable rod 522 perpendicular to itself, and the movable rods 522 of the first push plates 51 on both sides are inserted into the second ball sleeve 521, and no collision will occur during the movement, and the limit distance will not cause the movable rod 522 to fall off the second ball sleeve 521. The limit distance is the distance between the first push plate 51 being fully extended and the first push plate 51 being retracted. The movable rod 522 and the second ball sleeve 21 stabilize the movement trajectory of the first push plate 51. Preferably, the first transmission mechanism includes a first motor 53, a first rotating disk 54 provided on the first motor 53, and the first rotating disk 54 is coaxially fixedly connected to the output shaft of the first motor 53, and further includes a first connecting rod 55, a second connecting rod 56, and a third connecting rod 57; one end of the first connecting rod 55 is rotatably connected to the first rotating disk 54, and the other end of the first connecting rod 55 is rotatably connected to one end of the second connecting rod 56, such as Figure 6 As shown, the second connecting rod 56 is sleeved in a third ball sliding sleeve 59 fixedly arranged between the mounting frames 1, and the third ball sliding sleeve 51 is mounted between the mounting frames 1 through a mounting rod. The other end of the second connecting rod 56 is rotatably connected to the third connecting rod 57. A fixed movable seat 58 is provided on one side of the first push plate 51 close to the other first push plate 51. The movable seat 58 is provided with a movable hole 581 parallel to the first push plate 51. The end of the third connecting rod 57 away from the second connecting rod 56 is bent and inserted into the movable seat. In the movable hole 581, the first rotating disk 54, the first connecting rod 55, the second connecting rod 56, and the third connecting rod 57 move in the same plane. The rotation of the motor drives the first rotating disk 54 to rotate, and the first connecting rod 55 moves driven by the first rotating disk 54. The second connecting rod 56, which is rotatably connected to one end of the first connecting rod 55, is arranged in a fixed third ball sleeve 59, so it can only perform vertical linear reciprocating motion in the ball sleeve. The third connecting rod 57 connected to the other end of the second connecting rod 56 drives the push plates on both sides to perform linear reciprocating motion toward both sides.
[0032] like Figure 1 and Figure 3 As shown, the second bag pushing device includes a second push plate 61 perpendicular to and above the conveyor belt 2 and also includes a second transmission mechanism connected to the side of the second push plate 61 away from the first bag pushing device, and the second transmission mechanism enables the second push plate 61 to perform reciprocating linear motion along the conveying direction of the conveyor belt 2. Figure 3As shown, preferably, a support column 11 and a crossbeam 12 are also provided on the mounting frame 1 at the side of the second push plate 61 away from the first push plate 51, and the third ball bearing sleeve 59 is provided on the crossbeam 12. The support column 11 and the crossbeam 12 mainly play the role of fixing the sleeve. Preferably, the second transmission mechanism includes a second motor 64, a gear plate 641 provided on the second motor 64, and a rotating shaft 65 mounted on the mounting frame 1 and parallel to the Y axis. A shaft gear 651 coplanar with the gear plate 641 is fixedly installed on the rotating shaft 65. A toothed belt 66 is provided on the gear plate 641 and the shaft gear 651. A second rotating disk 67 is provided on the rotating shaft 65. A fourth connecting rod 68 is rotatably provided on the second rotating disk 67. The fourth connecting rod 68 is connected to the push plate 51. One end of the rod 62 is rotatably connected, and the second rotating disk 67, the fourth connecting rod 68, and the push rod 62 move in the same plane and are parallel to the first push plate 51. The operation of the motor drives the gear disk 641 to rotate, and the gear disk 641 drives the second rotating disk 67 to rotate through the toothed belt 66. The rotation of the second rotating disk 67 drives the fourth connecting rod 68 to move. Since the push rod 62 rotatably connected to one end of the fourth connecting rod 68 is coaxially arranged in the third ball sleeve 59, the fourth connecting rod 68 causes the push rod 62 to perform a linear reciprocating motion along the direction of the conveyor belt 2.
[0033] like Figure 3 As shown, preferably, the mounting frame 1 is provided with a mounting plate parallel to the conveyor belt 2, and two vertically upward axle seats are provided on the mounting plate. The rotating shaft 65 is set on the axle seats. The axle seats will not interfere with the movement trajectory of the fourth connecting rod 68 and the second rotating disk 67, and only provide support and fixing for the rotating shaft 65.
[0034] like Figure 5 There are four discharge conveyor belts 8 shown, and each conveyor belt 2 corresponds to two discharge conveyor belts 8. There is a light-transmitting gap between every two corresponding discharge conveyor belts. The transmitting part and the receiving part of the through-beam sensor are respectively provided above and below the gap, which can be fixed by installing additional brackets on both sides of the discharge conveyor belt. The through-beam sensor will not interfere with the movement of the bag, and the light path of the through-beam sensor is unobstructed except when the bag can block it. The bag will block the light path of the through-beam sensor when passing by, and the through-beam sensor counts once each time it passes.
[0035] It should be noted that, in addition to the lifting cylinder 72, the motion logic control of the conveyor belt 2 and the motion logic control of the lifting door 4 in the present invention also require the installation of the following equipment not shown in the figure to be realized. Since the following equipment belongs to the existing technology, only the principle is roughly described here. In addition to the lifting cylinder 72, a stable air source is required to provide kinetic energy for the lifting cylinder 72, as well as a PLC and a solenoid valve to control the on-off of the air circuit. The lifting cylinder 72 is also provided with an arrival sensor for detecting the status of the lifting cylinder 72. The conveyor belt 2 is driven by a motor interconnected with the PLC. First of all, it should be noted that the lifting door 4 remains in a closed state so that the number of bags is blocked by the lifting door when it does not reach the set standard. After the through-beam sensor detects that the number of bags passing through reaches the standard set by the program, the bag sorting continues for 5 seconds. Then the PLC sends a command to the solenoid valve to retract the lifting cylinder 72. After retracting to the limit position, the PLC sends a motion command to the motor of the conveyor belt 2 so that the bags can flow neatly into stacks and flow into the next link. Then the recorded value in the program is reset, and the counting is restarted to start the next bag sorting process.
[0036] The method of using the utility model is as follows:
[0037] like Figure 5 As shown, the device needs to be placed under the discharge conveyor belt 8 of the bag making machine. The bags on the discharge conveyor belt 8 of the bag making machine will fall into the bag sorting area, that is, the area enclosed by the lifting door 4, the first push plate 51, the side baffle 3 and the second push plate 61. It should be noted that the present invention is only suitable for paper-plastic bags or other plastic bags of a certain quality, which will not have too much posture change under the influence of air resistance in a short distance. Therefore, even if the bag body is skewed, it can fall into the bag sorting area. Before falling into the bag sorting area, the discharge conveyor belt has recorded the number of bags discharged through the shooting sensor, and the bag pushing plate operates to make the stacked bags neatly stacked together. When the detected number reaches the set value of the program, the bags are stopped from being dropped, the lifting gate is raised, and then the bags are sorted into neat bag piles by the repeated pushing of the first push plate 51 and the second push plate 61. At this time, if the number set in the program is reached, the PLC sends a stop command to the bag making machine discharge conveyor belt 8 to stop outputting bags, and then the lifting gate 4 is raised. After the lifting gate 4 is raised for 3 seconds, the bag sorting device conveyor belt 2 starts smoothly. After 3 seconds, the lifting gate 4 drops, and the arrival sensor on the lifting cylinder 72 sends a signal to restart the bag making machine discharge conveyor belt 8. The bag sorting device conveyor belt 2 stops and a new round of bag sorting begins. Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
