Description

Technical Field

[0001] This invention relates to the mechanism of a packing machine. Background Technology

[0002] The strapping machine includes a core mechanism, which comprises a heat-bonding mechanism, a sliding mechanism, a top-strap mechanism, and a strap-cutting mechanism. A series of cams mounted on the core shaft are driven by a core motor to control the movement of these mechanisms, thereby securing, cutting, and bonding the strapping. One type of strapping machine uses a strap-reaming mechanism to wrap the strapping around the item. To facilitate this strap-reaming, at certain stages of the process, one end of the strapping needs to be pressed upwards, and at other times, it needs to move laterally perpendicular to the strapping. This is accomplished by a strap-pressing mechanism. Furthermore, this strap-reaming mechanism also requires power to move around the object and simultaneously move back and forth relative to it.

[0003] The core motor controls components that move vertically, such as the top and cut strapping mechanisms, as well as components that move forward and backward, such as the sliding plate mechanism. It also controls all movements of the strapping feeding mechanism. This results in a relatively long core, making it too large in width, occupying a lot of space, and creating a non-compact structure. Furthermore, currently, the pressing mechanism is connected to the sliding plate of the core to achieve lateral movement. Pressing the strapping upwards is achieved by the upward rotation of the pressing component, which requires cantilever arms and multiple connecting links, making the structure complex and further increasing the overall complexity of the core. Summary of the Invention

[0046] Referring to the accompanying drawings, the packing machine includes a core mechanism. The core mechanism includes a first drive section, a core motor 101, and a core frame 102. The first drive section includes the core motor 101, a core shaft driven by the core motor, and a first control section. The first control section includes multiple cams mounted on the core shaft, each corresponding to a controlled object. The core mechanism includes a slide plate mechanism, a heat-bonding mechanism, a tape cutting mechanism, a tape sorting mechanism, and a tape pressing mechanism. The slide plate mechanism includes a slide plate 300 and a slide plate swing arm 301. The heat-bonding mechanism includes a heat-bonding head swing arm 401 and a heat-bonding head 400.

[0047] The mechanism is equipped with the strapping mechanism described in this invention. The strapping mechanism includes a swingable strapping assembly, which can move axially back and forth. The strapping assembly includes a swing arm 1 and a strapping member 2 movably connected to the swing arm 1, allowing the strapping member 2 to move away from and towards the swing axis, i.e., the center line of the swing axis 11. The strapping assembly can be driven axially back and forth by the mechanism motor 101. The mechanism is equipped with a second drive section, which includes a second drive motor 3 and a second control section. The second drive motor 3 is arranged perpendicular to the mechanism motor 101 and can be positioned in the thickness direction of the packing machine. Preferably, the second drive motor 3 is arranged on the side of the mechanism shaft, opposite to the sliding swing arm in the mechanism. The axial back and forth movement of the strapping assembly and the swinging of the strapping assembly are driven by different motors. Furthermore, when the strapping assembly swings, the second control section controls the strapping member to move away from and towards the swing axis.

[0048] The second control section includes a second control cam 4 disposed outside the movement shaft. The second control cam 4 is connected to a mechanism that can raise and lower its cam surface, allowing its cam surface to be raised and lowered. The strap guide 2 is connected to a second reset mechanism and a second control cam engaging component 23, so that the second control cam engaging component 23 and the second control cam 4 are tightly engaged. The second reset mechanism uses a reset spring 24, arranged between the rocker arm 1 and the strap guide 2. The strap guide includes a horizontal portion 21 and a vertical portion 22. The horizontal portion 21 is used for strap guiding, and the vertical portion 22 is used for an insert-type sliding connection with the rocker arm 1. The second control cam engaging component 23 is connected to the vertical portion 22, and the vertical portion 22 is also connected to the reset spring 24. The second control cam engaging component 23 may be a roller.

[0049] The first control section is equipped with a control section corresponding to the second control cam. The belt feeding mechanism is also equipped with a third reset mechanism. The control section corresponding to the second control cam and the third reset mechanism cooperate to adjust the height of the cam surface of the second control cam 4. The lowest descending position of the cam surface of the second control cam 4 is lower than the lowest position of the second control cam mating component 23, so that the belt feeding assembly returns to above the second control cam through axial movement, and then drives the second control cam 4 to rise, so that the cam surface rises to the working position and contacts the second control cam mating component 23. The third reset mechanism uses a reset spring 40, which is arranged between the second control cam 4 and the movement frame 102.

[0050] The mechanism for raising and lowering the cam surface height includes a rocker arm 6, which is rotatably mounted on the movement frame 102. The rocker arm 6 has a lifting working part for lifting the second control cam 4. The rocker arm 6 also has a controlled part that is controlled by a third control part. The second control cam 4 is rotatably mounted on the movement frame 102, increasing the speed and sensitivity of height adjustment. The third control part includes a third control cam 60, which is fixed to the second movement shaft 104. The height of the second control cam 4 is higher than the height of the third control cam 60. The lifting working part can be a roller 61, and the controlled part can be a roller 62. The second control cam 4 can also be mounted using other movable mounting structures such as sliding mounting, allowing for adjustment of its cam surface height.

[0051] Furthermore, a vertical slot 41 can be provided on the second control cam 4, and the return spring 40 is movably connected to the vertical slot 41 via the insert rod 42, thereby movably connecting the second control cam 4 to the third reset mechanism.

[0052] The tape feeding mechanism also includes a sliding table 7. The tape feeding assembly and the second drive motor 3 are mounted on the sliding table 7. The sliding direction of the sliding table 7 is the axial forward and backward movement direction of the tape feeding assembly. The sliding table 7 is equipped with a first reset mechanism. The first drive motor 101 and the first reset mechanism cooperate to drive the sliding table and the structure located on the sliding table 7 (including the second drive motor 3 and the tape feeding assembly) to slide forward and backward. The first driving part includes a first control part, which controls the forward and backward movement of the sliding table. The first control part includes a first control cam 70, which is fixed on the second core shaft 104. The sliding table is provided with a controlled component that cooperates with the first control cam 70, such as a roller 71. The sliding table 7 can also use other drive mechanisms, such as cylinder drive.

[0053] The first reset mechanism uses a reset spring 73, which is arranged between the sliding table 7 and the mechanism frame 102; the mechanism frame 102 is provided with a guide rail 105 for the sliding table 7, and the sliding table 7 is slidably connected to the guide rail 105 through a slider 72.

[0054] The movement frame 102 of the present invention includes a left upright plate 1021 and a right upright plate 1022. The movement shaft includes a first movement shaft 103 and a second movement shaft 104 that are parallel to each other. The first movement shaft 103 and the second movement shaft 104 are perpendicular to the left upright plate 1021 and the right upright plate 1022, respectively. The two ends of the first movement shaft 103 and the second movement shaft 104 are connected to the left upright plate 1021 and the right upright plate 1022, respectively. One end of the first movement shaft 103 is connected to the second movement shaft 104 through a transmission mechanism, wherein the transmission mechanism is a gear connection structure 106. The other end of the first movement shaft 103 is connected to the movement motor 101. The first core shaft 103 is located near the first side of the core frame 102, while the second core shaft 104 is located near the second side of the core frame 102. The swing arm 1 of the strapping assembly is located on the second side of the core frame 102 and performs the back-and-forth movement on the second side of the core frame. The slide swing arm 301 and the hot-stick head swing arm 401 are located on the first side of the core frame. The second drive motor 3, which independently drives the strapping assembly to swing, is arranged perpendicular to the core motor 101.

[0055] The cam 302 that controls the swing of the skateboard swing arm 301 and the cam 402 that controls the swing of the hot-stick head swing arm 401 are both mounted on the first core shaft 103.

[0056] The cams controlling the lifting and lowering of the belt pressing and cutting mechanisms are mounted on the second core shaft 104. Wherein:

[0057] Cam 502 is a cam that controls the lifting and lowering of the tape cutting mechanism. In the tape feeding direction, the one closer to the tape head 201 is the downstream (the tape head 201 refers to the head of the packing tape during the tape feeding movement, and the tape head 201 to the tape tail 202 is the packing tape that is cut by the cutter and tied to the object). The cutter 500 is located upstream of the hot-sticking head 400. The cutter 500 has a first left pressure block 501 that lifts and lowers synchronously with it and cooperates with the hot-sticking head 400 to press the hot-sticking part of the tape tail onto the hot-sticking head 400.

[0058] Cam 602 is a cam that controls the lifting and lowering of the second left pressure block 601 of the left top belt mechanism. The second left pressure block 601 is located to the left of the first left pressure block 501 and is used to press the portion of the packing strap head upstream of the heat-bonding part onto the slide plate 300.

[0059] Cam 702 is a cam that controls the lifting and lowering of the first right pressing block 700 of the first right pressing mechanism. The first right pressing mechanism includes a pressed block 701 and a first right pressing block 700, as shown below. Figure 8 As shown, the pressing block 701 and the first right pressing block 700 cooperate to clamp the packing tape 200 (i.e., the head of the tape to be packed next) connected to the tape roll at the cutting point of the cutter. In the tape feeding direction, the side closer to the tape head is downstream, and the first right pressing block 700 is located upstream of the cutter 500. The pressing block 701 is connected to the pressing block swing rod 703, and the cam 704 that controls the swing of the pressing block swing rod 703 is mounted on the first core shaft 103.

[0060] The second right pressure band mechanism includes a drive part and a swingable pressure band assembly. The pressure band assembly includes a second right pressure block swing arm 5 and a second right pressure block 800 movably connected to the second right pressure block swing arm 5, which allows the second right pressure block 800 to move away from and towards the swing axis. The swing axis is parallel to the movement axis. Reference numeral 50 is the swing axis of the second right pressure block swing arm 5.

[0061] The second right pressing mechanism is equipped with an upper lifting mechanism, which includes a second right lifting block 801. The second right pressing mechanism includes a cam 804 for controlling the swing of the second right pressing block lever 5 and a cam 802 for controlling the lifting of the right lifting block, a first reset part, and a second reset part. The second right pressing block lever swings under the control of the cam 804, which controls the swing of the second right pressing block lever, driven by the cooperation of the mechanism motor 101 and the first reset part. The second right lifting block 801 rises and falls under the control of the cam 802, which controls the lifting of the right lifting block, driven by the cooperation of the mechanism motor 101 and the second reset part. The second right lifting block 801 cooperates with the second right pressing block 800 to lift the second right pressing block 800 and press the end of the packing strap onto the slide plate 300. The cam 804 for controlling the swing of the second right pressing block lever is mounted on the first mechanism shaft, and the cam 802 for controlling the rise and fall of the second right lifting block is mounted on the second mechanism shaft 104. Cams 802 and 804 are arranged side by side along a direction perpendicular to the core shaft and are fixed on the first core shaft 103 and the second core shaft 104 respectively. That is, they are arranged along the thickness direction of the packing machine, which can make more rational use of space and simplify the transmission structure.

[0062] The second right pressure block swing arm 5 is separated from the slide swing arm 301 and swings independently relative to the slide swing arm 301; its swing axis 50 is parallel to the movement axis.

[0063] The second right pressure block rocker arm 5 may be equipped with a cam mating part, such as a roller 52, that cooperates with the cam 804.

[0064] The upper lifting mechanism includes a guide groove 81 and a second right lifting block 801. The guide groove 81 can be disposed on the movement frame 102. The second right lifting block 801 includes a guide portion 84 and is slidably connected to the guide groove 81, allowing it to move upward and downward under the guidance of the guide groove 81. The lower end of the second right lifting block 801 engages with the cam 802 via a cam engagement component (which can be a roller 83). The second right pressure block 800 includes a horizontal portion 91 and a vertical portion 92. The vertical portion 92 is movably connected to the second right pressure block swing arm 5. The horizontal portion 91 extends above the second right lifting block 801 and can be lifted by the second right lifting block 801. The upper lifting mechanism may be equipped with a reset mechanism for the upper lifting component.

[0065] The second right pressure block swing rod 5 is provided with a guide groove 51. The vertical part 92 and the guide groove 51 are slidably connected and can move up and down under the guidance of the guide groove 51.

[0066] A reset mechanism is provided between the second right pressure block 800 and the second right pressure block swing rod 5, so that the second right pressure block 800 can closely cooperate with the second right top block 801, improving the coordination of the work and the lifting effect. The reset mechanism can be a reset spring 93.

[0067] The second reset part is located between the movement frame 102 and the second right top block 801, and the second reset part can be a reset spring 82. The first reset part is located between the movement frame 102 and the second right pressure block rocker arm 5, and the first reset part can be a reset spring 53.

[0068] Referring to the attached drawings, the skateboard mechanism includes a skateboard swing arm 301, a swing shaft 50, and a skateboard 300. The swing shaft 50 is perpendicular to the left upright plate 1021 and the right upright plate 1022. The left and right sides of the swing shaft 50 are connected to the lower parts of the left upright plate 1021 and the right upright plate 1022, respectively. The slide rocker arm 301 is connected to the swing shaft 50 and can swing under the control of the control structure. The upper ends of the slide plate 300 and the slide rocker arm 301 are fixedly connected. The left and right sides of the mechanism frame 102 are connected to the left cantilever rod 303 and the right cantilever rod 304, respectively. The upper ends of the left cantilever rod 303 and the right cantilever rod 304 are respectively cantilevered above the mechanism and located on both sides of the slide plate. The upper ends of the left cantilever rod 303 and the right cantilever rod 304 are provided with guide rails 3041. The slide plate 300 is provided with a guide engagement structure 310 that slides and guides the guide rails 3041 on the left cantilever rod 303 and the right cantilever rod 304. The guide rail 3041 can be a protruding guide rail, and correspondingly, the guide mating structure 310 is groove-shaped for the protruding guide rail to be inserted. The guide rail can also be groove-shaped and the guide mating structure 310 is a protrusion that can be inserted into the groove-shaped guide rail.

[0069] The skateboard swing arm 301 is located on the first side of the mechanism frame 102, and the swing shaft 50 is located below the second mechanism shaft 104, which helps to make the skateboard 300 run in a basically horizontal manner and cooperate with the guide rail 3041; the first mechanism shaft 103 is provided with a cam 302 to control the swing of the skateboard swing arm 301, and the reference numeral 306 is the return spring of the skateboard swing arm 301, so that the roller 307 on the skateboard swing arm 301 can be in close contact with the cam 302.

[0070] As shown in the figure, the sliding rocker arm 301 is C-shaped facing the second side of the movement frame, which neither interferes with the internal structure of the movement nor prevents the swing axis 50 from being located below the second movement axis 104. The guide rail 3041 is a horizontal motion guide structure. When the sliding rocker arm 300 slides to the position where it engages with the upper top structure in the movement, it is in a horizontal state. The upper top structure is located above the second movement axis 104.

[0071] The left cantilever rod 303 and the right cantilever rod 304 each include a vertical section 308 and an upward-sloping section 309 towards the center of the movement. This design provides better stress distribution and support for the slide plate 300. The movement frame 102 includes a guide frame 1023 for guiding the upper structure. The left and right sides of the guide frame 1023 are connected to the left upright plate 1021 and the right upright plate 1022. In this embodiment, the vertical section 308 is connected to the guide frame 1023 in the movement frame 102. A guide rail 3041 is provided at the end of the upward-sloping section 309. The return spring 306 of the slide plate swing arm is connected between the slide plate swing arm and the vertical section 308 of the cantilever rod, providing better return performance.

[0072] This invention requires only one sliding plate, eliminating the need for a lower sliding plate, its swing mechanism, and swing control mechanism. The sliding plate mechanism is supported and guided by a cantilever rod, resulting in a simple structure, smooth operation of the sliding plate, and a reasonable structure and stress distribution of the cantilever rod, which helps extend its service life and provide better support for the sliding plate. This invention decomposes the drive of the tape feeding mechanism, allowing for individual power to drive its rotation, while forward and backward movement is driven by other power sources, reducing the size of the mechanism in the width direction of the packing machine. Furthermore, the mechanism can use two rotating shafts to control the movement of the components: one shaft controls the up-and-down or linear movement component, and the other controls the swing component, resulting in a clear division of labor and a compact structure. It also facilitates the distributed power drive and vertical layout of the tape feeding mechanism. Moreover, the tape pressing and positioning mechanism, even after separating from the sliding plate, can directly act on the tape pressing component on the swing rod via a swing rod and a separate upward lifting mechanism. This ensures the lateral forward and backward movement function of the tape pressing and positioning mechanism while improving the upward lifting effect and contributing to increased service life.
