Detailed ways

As shown in Figure 1, this high-speed film strapping machine includes a frame, a film conveying system 1, a box feeding mechanism 2, a box stacking mechanism 4, a first box pushing mechanism 3, a second box pushing mechanism 5, and a longitudinal pushing mechanism 6. , The third box pushing mechanism 7, and the box sealing mechanism 8. The film conveying system 1 is used for film supply and film delivery; the box feeding mechanism 2 is used for conveying medicine boxes; the box stacking mechanism 4 is used for stacking a certain number of medicine boxes; the first box pushing mechanism 3 is used for stacking the medicine boxes. All the boxes are pushed forward; the second box pushing mechanism 5 is used to push the medicine boxes of the set number of rows forward; the longitudinal pushing mechanism 6 is used to push the medicine boxes pushed out by the second pushing box mechanism 5 longitudinally; the third pushing box The mechanism 7 is used for pushing the medicine box pushed by the longitudinal pushing mechanism 7 forward; the box sealing mechanism 8 is used for wrapping the medicine box pushed by the third pushing mechanism 7 through a film.

As shown in Figures 1 and 2, the box feeding mechanism 2 is an ordinary belt conveying mechanism. The medicine boxes from the cartoning machine first enter the box feeding mechanism 2, and the box feeding mechanism 2 is transported forward; in the box feeding mechanism 2 is provided with a box pressing mechanism 20 at the front end. The box pressing mechanism 20 has a row of pressing wheels. The medicine boxes are squeezed together back and forth under the pressure of the pressing wheels and the driving force of the box feeding mechanism 2 and transported forward. Enter to the stacking mechanism 4.

As shown in Figures 1 and 8, the stacking mechanism 4 includes two stacking components arranged on the left and right, each stacking component includes a supporting bar 41, a lifting bar 40, and a lower pressing bar 43. The supporting bar 41 is rotatably arranged and It has a tendency to rotate inwardly (you can set the spring 42 on the outside to let the spring 42 act on the support bar 41, so that the support bar 41 has a tendency to rotate inwardly, or you can support the support bar 41 by shifting its center of gravity to the inside. The bar 41 has a tendency to rotate inwardly), the bottom surface of the support bar 41 has an inclined surface, the lifting bar 40 is in transmission connection with the lifting power source that drives the lifting bar 40 to go up and down. On the side guide plate 44. When the box feeding mechanism 2 transports a row of medicine boxes H on the horizontal plane to the two left and right lifting bars 40 (for example, four in a row in FIG. 2), the lifting power source drives the lifting bars 40 to move this row of medicine boxes to Lift up, because the support bar 41 is rotatable, and its bottom surface has a slope, so the support bar 41 is lifted and rotated by the medicine box, and when the medicine box comes up, the support bar 41 turns again under the action of the spring 42 On the inside, return to the original position, so that the support bar 41 is supported on the bottom of the medicine box. In such a cycle, rows of medicine boxes in the up and down direction are stacked, and since the lower pressing bar 43 can be raised and lowered on the side guide plate 44, the lower pressing bar 43 is always pressed on the uppermost row of medicine boxes. The stacking of the boxes keeps rising, so that the pill boxes always remain stable during the stacking process.

After the box stacking mechanism 4 stacks the medicine boxes to a set number of layers, the first box pushing mechanism 3 pushes all the stacked medicine boxes forward. As shown in Figures 1 and 9, the first box pushing mechanism 3 includes a material pushing plate 31, a horizontal sliding seat 32, a horizontal guide rail 35, and a power source 36. The horizontal sliding seat 32 is slidably arranged on the horizontal guide rail 35, and the material pushing The plate 31 is arranged on the horizontal sliding seat 32. Driven by the power source 36, the horizontal sliding seat 32 moves, and the pushing plate 31 pushes the medicine box forward. The combination of the power source 36 and the horizontal guide rail 35 can be an electric cylinder. technology.

In order to make the pushing plate 31 move along the circular track, the present invention is provided with a vertical sliding seat 34 on the horizontal sliding seat 32, and the pushing plate 31 is slid on the vertical sliding seat 34 through the vertical guide rail 33 (the pushing plate 31 is connected to the vertical guide rail 33, and the vertical guide rail 33 is slidably arranged on the vertical sliding seat 34); on one side of the horizontal guide rail 35 is provided a vertical guide groove plate 38, the guide groove plate 38 is provided with an annular guide groove 380, the lower section of the annular guide groove 380 has an extension guide groove 381 extending forward (the extension guide groove 381 communicates with the lower section of the annular guide groove 380 and is on the same straight line), and the upper section of the annular guide groove 381 has a climbing section 3801, the climbing section 3801 of the annular guide groove 380 is connected to the extension guide groove 381; and the vertical guide rail 33 is provided with a guide wheel 330, and the guide wheel 330 is in the annular guide groove 380; in addition, the guide groove plate 38 is hinged There is a one-way stopper 39. The swing of the one-way stopper 39 has a first state in which the guide wheel 330 enters the extension guide groove 381 from the lower section of the annular guide groove 380 and restricts the guide wheel 330 from entering the ring shape from the extension guide groove 381. The lower section of the guide groove 380 allows the guide wheel 330 to enter the second state of the upper section of the annular guide groove 380.

Its working principle is as follows: as shown in Figure 9, when the material needs to be pushed, the power source 36 drives the horizontal sliding seat 32 to move forward on the horizontal guide 35, so that the pushing plate 31 pushes the medicine box forward, as shown in Figure 11. As shown, since the one-way stopper 39 has a first state in which the guide wheel 330 enters the extension guide groove 381 from the lower section of the annular guide groove 380 (that is, the one-way stopper 39 swings upwards), the pusher plate 31 comes to Foremost, the pushing work is completed, and at this time the guide wheel 330 is in the extension guide groove 381, and then the power source 36 drives the horizontal sliding seat 32 to move back on the horizontal guide 35, because the guide wheel 330 is restricted from the extension guide groove 381 381 enters the lower section of the annular guide groove 380 and allows the guide wheel 330 to enter the second state of the upper section of the annular guide groove 380 (that is, the one-way stopper 39 swings and resets under the action of its own gravity, and the one-way stopper 39 blocks the guide wheel 330 Enter the lower section of the annular guide groove 380 from the extension guide groove 381), so that the guide wheel 330 can only move upward along the climbing section 3801 of the annular guide groove 380 and reach the upper section of the annular guide groove 380, while the vertical guide 33 is Move upward on the vertical sliding seat 34, so that the pusher plate 31 rises and returns. Since the pusher plate 31 is raised, even if the pusher plate 31 is in the process of returning, it will not interfere with the working space of the stacking mechanism 4. In this way, the box stacking mechanism 4 can run continuously, which improves the speed of the whole machine.

Since the vertical rail 33 will pass in front of the one-way stopper 39, if the two are in the same plane, they will definitely interfere with each other. Therefore, the position of the one-way stopper 39 is closer to the vertical guideway 33. For this reason, as shown in Fig. 11, at the intersection of the extended section guide groove 381 on the guide groove plate 38 and the annular guide groove 380, there is a swing groove 382 for the one-way stopper 39 to swing. The depth of the swing groove 382 is shallower than that of the annular guide groove 380. The depth of the guide groove 380, the one-way stopper 39 is located in the swing groove 382, through this structure, the path of the annular guide groove 380 is not affected, and at the same time the one-way stopper 39 is in the swing groove 382, avoiding the vertical Rail 33.

In order to make the guide wheel 330 more smoothly move from the extension guide groove 381 to the upper section of the annular guide groove 380, as shown in FIG. And the arc edge 391 connecting the climbing section 3801 of the annular guide groove and the extending section guide groove 381. When the guide wheel 330 transitions from the extension guide groove 381 to the annular guide groove climbing section 3801, it moves along the arc edge 391 of the one-way stop 39, and then along the straight edge 390 of the one-way stop 39 Enter the climbing section 3801 of the circular guide trough.

Since there is only one guide wheel 330 on the upper part of the vertical guide rail 33 in the annular guide groove 380, that is to say, the vertical guide rail 33 is only supported at this point, and the vertical guide rail 33 may not be stable enough to operate. In order to solve this problem, as shown in Figure 10, In the present invention, a tension spring 37 is connected to the horizontal sliding seat 32. The tension spring 37 is located on the rear side of the guide groove plate 38. The upper end of the tension spring 37 pulls the upper end of the vertical guide rail 33. Pulled by the tension spring 37, both the lower end and the upper end of the vertical guide rail 33 are stressed, so that the vertical guide rail 33 can maintain balance and run more stably.

After the first push box mechanism 3 pushes out all the medicine boxes, the second push box mechanism 5 pushes out the set number of medicine boxes. Set), just push the distance between two rows of medicine boxes.

As shown in Figure 12, the second box pushing mechanism 5 includes two left and right box pushing rods 50 and two driving force sources 57. One of the box pushing rods 50 is connected to the screw rod 53 through a positive screw sleeve 51, and the other pushing The box rod 50 is connected to the screw rod 53 through the reverse screw sleeve 52. The screw rod 53 is in transmission connection with the motor 54. The motor 54 is installed on the movable slide 55. The movable slide 55 is slidably arranged on the linear guide 56. The source 57 is in transmission connection with the movable slide 55. When the second box pushing mechanism 5 is working, the two pushing force sources 57 drive the moving slide 55 to move on the linear guide 56, and the two left and right box pushing rods 50 push the medicine box to move a certain distance, and the number of rows will be set. The medicine box is pushed forward. When the push rod 50 pushes all the medicine boxes, the motor 54 drives the screw 53 to rotate. Because one push rod 50 is connected to the screw through the positive screw sleeve 51, the other push rod 50 is connected to the screw rod 53 by the reverse screw sleeve 52, so one push box rod 50 moves to the left on the screw rod 53, and the other push box rod 50 moves to the right on the screw rod 53, so that there are two push boxes on the left and right. The rod 50 is opened, and then the two driving force sources 57 drive the moving slide 55 to return, and the ejector plate 31 of the first box pushing mechanism 3 is just in the middle of the double box pushing rod 50, and the paths do not overlap, so the first box pushing mechanism 3 It can work continuously, and the speed of the whole machine can be increased through the square walking track of the two push box rods 50 on the left and right.

After the second box pushing mechanism 5 pushes the medicine boxes of the set number of rows, the longitudinal pushing mechanism 6 pushes these medicine boxes to one side longitudinally. As shown in Fig. 13, the longitudinal pushing mechanism 6 includes a longitudinal pushing plate 60 and a longitudinal pushing force source 61 that drives the longitudinal pushing plate 60 to move longitudinally. Driven by the longitudinal pushing force source 61, the longitudinal pushing plate 60 moves longitudinally to move the medicine box Push to the station where the third box pushing mechanism 7 is located. As shown in Figure 14, the third box pushing mechanism 7 includes three pushing plates 70 and three pushing power sources 71 that drive the three pushing plates 70 to move back and forth. Driven by the three pushing power sources 71, the three pushing plates 70 push the medicine box to At the station where the box sealing mechanism 8 is located, the box sealing mechanism 8 binds these medicine boxes.

As shown in Figure 2 and Figure 15, the box sealing mechanism 8 includes an upper box sealing knife 80 and a lower box sealing knife 81. Two damping plates 82 are formed, and bristles 83 are provided on the damping plates 82. When the third box pushing mechanism 7 moves the medicine box forward, the standing film is pushed forward and stretched by the medicine box, and wraps the medicine box. When the medicine box is pushed to the damping area, the bristles 83 medicine box A reverse force buffers the moving speed of the pill box, so that the film better wraps the pill box, and then the upper box sealing knife 80 interacts with the lower box sealing knife 81 to cut the film, so that the film is completely bound. At the same time, the cut-off film on the upper and lower ends of the medicine box is sealed together, thereby completing the binding work of the medicine box.

As mentioned above, the film is conveyed by the film conveying system 1. As shown in FIG. 3, the film conveying system 1 includes two film supply units 10 located above and two film supply units 10 located below, each The film supply unit 10 includes a film roll 101 for placing a film roll, a film sealing and cutting mechanism 103 for film cutting and sealing, and a film break detector 102 for film detection. The film break detector 102 and the film sealing and cutting mechanism Signal connection between 103.

As shown in FIG. 6, after the two film supply units 10 above and the two film supply units 10 below have placed the film rolls, the film needs to be spliced in advance. The film bonding principle of the two film supply units 10 above is the same as the film bonding principle of the two film supply units 10 below. Principle: As shown in Figure 7, the film supply unit 10 on the left normally supplies film, and the film roll on the film supply unit 10 on the right is pulled over and placed in the film sealing and cutting mechanism 13 of the film supply unit on the left, so that the film on the left film roll and the film on the right The film rolls are arranged side by side. When the film break detector 102 of the left film supply unit detects that the film on the left film roll is used up (the film break detector 102 can be a photoelectric eye detector or a mechanical detector, as long as it can detect The film is used up), the film break detector 102 transmits the signal to the film sealing and cutting mechanism 103 of the left film supply unit (that is, the two signals are connected), the film sealing and cutting mechanism 103 cuts the film on the left film roll, and simultaneously rolls the right film The head of the film is heat-sealed and joined to the tail of the left film roll, so that the film roll on the right is connected and the film continues to be supplied. At the same time, the new film roll is manually placed on the film roll 101 of the left film supply unit, and the The new film roll is pulled over and placed in the film sealing and cutting mechanism of the film supply unit 10 on the right. In such a cycle, the machine does not need to be shut down, the operation is simple, and the film connection is reliable.

As shown in Figure 4, the film sealing and cutting mechanism 103 includes a film cutter 104 and a heat sealing seat 105. The film cutter 104 and the heat sealing seat 105 are driven by a sealing and cutting power source to achieve interaction. The film cutter 104 has the function of cutting the film. The blade 106 and the heat cover 107 interacting with the heat sealing seat 105. When the signal from the film break detector 102 is received, the sealing and cutting power source drives the film cutter 104 to interact with the heat-sealing seat 105, and the blade 106 of the film cutter 104 cuts the lower part of the film on the left and right sides, and the film cutter 104 The heat cover 107 interacts with the heat sealing seat 105 to heat seal the upper parts of the left and right films together to form a joint surface 108, thus completing the film splicing.

When the film is spliced, the film exit point of the film supply unit will change, as shown in Figures 3 and 5. When the film roll on the right is reconnected, the film exit point of the film supply unit 10 on the right will change. To the right, in order to prevent friction between the film and other components, it is necessary to keep the film in the film sealing and cutting mechanism 103 in a vertical tension state. To this end, the present invention is provided with a film control mechanism 11 between the two film supply units 10 above and between the two film supply units 10 below. As shown in FIG. 5, the film control mechanism 11 includes a film control roller 110 and a film control power source 111 that drives the film control roller 110 to move left and right, and a signal connection between the film control power source 111 and the film break detector 102. When the film sealing and cutting mechanism 103 finishes cutting the film, the film break detector 102 transmits a signal to the film control mechanism 11, and the film control power source 111 drives the film control roller 110 to move to the right, so that the film exit point of the right film supply unit 10 remains vertical The tensioned state of the film prevents friction between the film and other parts and ensures the normal transport of the film.

There are many ways for the film control power source 111 to control the left and right movement of the film control roller 110. For example, the film control roller 110 is installed on a sliding seat, and the film control power source 111 drives the sliding seat to move. The present invention specifically provides one type: as shown in FIG. 5, the film control roller 110 is connected to the film control swing arm 112, one end of the film control swing arm 112 is hinged, and the film control power source 111 is connected to the film control swing arm 112 in transmission. Driven by the film control power source 111, the film control swing arm 112 swings left and right, so that the film control roller 110 can move left and right.
