Description

Technical Field

[0001] The utility model relates to the technical field of cartoning machines, and more particularly to a material pushing device for high-speed cartoning machines. Background Art

[0002] Automatic cartoning machines are primarily used in the pharmaceutical, health product, food, and cosmetics industries to automatically carton and package materials and instructions. The existing cartoning machine's pusher mechanism consists of two support frames, a synchronously rotating chain drive system mounted on each support frame, a material chute plate, and a pusher mechanism mounted on each chain drive system.

[0003] For example, the invention patent application publication date is January 19, 2011, with publication number CN101948018A and titled “Push Rod Device for Automatic Cartoning Machine”. It discloses a push rod device for automatic cartoning machine, comprising a mounting frame on which two sets of chain transmission mechanisms are symmetrically mounted. A plurality of material trough plates are evenly distributed on the two chains of the two sets of chain transmission mechanisms. Two guide shafts are provided between the two chains, respectively, below the corresponding material trough plates. A sliding push rod inserted into the material trough plate is installed between the two guide shafts. A guide rail is provided on the mounting frame along the chain transmission direction. A rolling bearing inserted into the guide rail is provided on the sliding push rod. The sliding push rod performs intermittent reciprocating motion under the action of the guide rail.

[0004] The above-mentioned prior art box-entry push rod device has a complex structure and requires a guide rail to guide and limit the motion trajectory of the sliding push rod, so that the sliding push rod can perform intermittent reciprocating motion under the action of the guide rail. The stroke and trajectory of the sliding push rod of the existing box-entry push rod device are fixed and cannot be adjusted. When the material specifications change, a new box-entry push rod device needs to be designed according to the new material specifications, and the versatility is poor. The above-mentioned existing box-entry push rod device can only push the material into the box, and cannot press the material into the box. If a pressing plate is added to the existing box-entry push rod device, while pushing the material into the box, the material is pressed and pushed into the packaging box, the structural changes are relatively large, further increasing the structural complexity of the existing box-entry push rod device. Utility Model Content

The purpose of the present invention is to solve the problems in the prior art of the box-entry push rod device, which is complex in structure, poor in versatility, and unable to press the material while pushing the material. The present invention adopts a power actuator that moves at least in the X direction and the Y direction as the power source of the push rod assembly, wherein the power actuator includes a moving platform, a static platform, a transmission assembly and a power source, and the power source drives the moving platform to move relative to the static platform in the X and Y directions through the transmission assembly. The push rod assembly is assembled on the moving platform, and the push rod assembly includes at least one push rod, and a press plate is arranged above the push rod, and the press plate is connected to the press plate driving mechanism. The press plate driving mechanism is assembled on the moving platform to drive the press plate to reciprocate relative to the push rod. The utility model replaces the existing circulating chain and guide rail by a power actuator that moves in the X direction and the Y direction. The working stroke and trajectory of the push rod can be adjusted by adjusting the action parameters. The adjustment is simple and the versatility is high. In addition, a pressing plate is added above the push rod, which is beneficial to the posture of the material pushed by the push rod, so that the material can be pushed into the packaging box more smoothly, which is beneficial to the smooth progress of the material pushing and boxing process, improves the material pushing and boxing efficiency, and reduces the material pushing and boxing failure rate.

[0006] In order to solve the above problems in the prior art, the present invention is implemented through the following technical solutions.

[0008] Further preferably, the power actuator is a two-axis parallel manipulator.

[0009] Further preferably, the press drive assembly includes a press drive motor, a press screw and a press transmission frame. The press drive motor drives the press screw to rotate. The press screw is rotatably assembled on the moving platform through a bearing mounting seat. The press transmission frame is slidably assembled on the moving platform.

[0023] The following will be combined with the drawings of the present invention specification to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] As a preferred embodiment of the present invention, refer to the attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, this embodiment discloses a pushing device for a high-speed cartoning machine, including a power actuator 1 and a pushing rod assembly 7, the power actuator 1 includes a static platform 2, a dynamic platform 3, a transmission assembly 4 and a servo drive assembly 5, the servo drive assembly 5 drives the dynamic platform 3 to move relative to the static platform 2 at least in the X and Y directions through the transmission assembly 4; the pushing rod assembly 7 is assembled on the dynamic platform 3; the pushing rod assembly 7 includes at least one pushing rod 6, and a pressing plate 8 is provided above the pushing rod 6, the pressing plate 8 is assembled on the dynamic platform 3 through a pressing drive assembly 9, and the pressing drive assembly 9 drives the pressing plate 8 to reciprocate relative to the pushing rod 6; the pressing plate 8 is configured so that when the pushing rod 6 pushes the material, the pressing plate 8 extends out above the material pushed by the pushing rod 6, and after the pushing plate and the material enter the packaging box, the pressing plate 8 is pulled out of the packaging box and reset together with the dynamic platform 3 and the pushing rod 6.

[0025] In this embodiment, a power actuator 1 with at least two degrees of freedom is used as the driving power mechanism of the push rod assembly 7. The power actuator 1 can realize movement in the X and Y directions within its working space, so that the movement stroke and trajectory of the push rod 6 can be a parabola or a circular arc trajectory. For the adjustment of the stroke and trajectory of the push rod 6, it is only necessary to control the driving motor of the power actuator 1. It has a simple structure, and the stroke and trajectory of the push rod 6 are adjustable, which has better versatility and can still be used even after the material specifications change.

[0026] Furthermore, a pressing plate 8 is provided above the push rod 6. By providing the pressing plate 8, it is possible to press the material while pushing the material, so that when the material is pushed into the box, it can be better pushed into the packaging box, avoiding collision between the material and the packaging box and affecting the packaging. The power actuator 1 of the present invention includes a moving platform 3, on which a pressing drive assembly 9 can be assembled, so as to achieve the withdrawal of the pressing plate 8 after it enters the packaging box. When the pressing plate 8 of the present invention pushes the material together with the push rod 6, the pressing plate 8 is located above the material and enters the packaging box together with the material. Thereafter, driven by the pressing drive assembly 9, the pressing plate 8 is withdrawn from the packaging box. After the pressing plate 8 is withdrawn from the packaging box, it is reset together with the moving platform 3 and the push rod 6. This arrangement ensures that when the pressing plate 8 is withdrawn, the material is blocked by the push rod 6, avoiding the withdrawn pressing plate 8 from the packaging box.

[0027] As an example of this embodiment, the power actuator 1 can be an XY linear module, a cross slide, or other actuator. The XY linear module and the Y linear module are mounted on the X linear module. The X linear module is mounted on the static platform 2. The X linear module drives the Y linear module to reciprocate along the X axis. The dynamic platform 3 is mounted on the Y linear module. The Y linear module drives the dynamic platform 3 to reciprocate along the Y axis. Under the combined action of the X linear module and the Y linear module, the dynamic platform 3 can reciprocate in both the X and Y directions relative to the static platform 2. The structural principle of the cross slide is the same as that of the XY linear module.

[0028] As an example of this embodiment, the power actuator 1 has three degrees of freedom. On the basis of the above-mentioned XY model, adding a Z-axis module can achieve three degrees of freedom, thereby allowing the moving platform 3 to reciprocate in the X-axis, Y-axis and Z-axis directions.

[0029] As a preferred embodiment of this embodiment, refer to the attached Figure 1 and attached Figure 3As shown, the power actuator 1 is a two-axis parallel manipulator, which has a stable structure and occupies a small space. Compared with the XY axis operation module, it occupies a smaller space and is more convenient for layout. As an example, the two-axis parallel manipulator can be a long-short arm two-axis parallel manipulator, an equal-arm two-axis manipulator, etc.

[0030] As an implementation method of this embodiment, the power actuator 1 can also use a serial manipulator.

[0031] As another embodiment of this embodiment, refer to the attached Figure 1 and attached Figure 3 As shown, the press drive assembly 9 includes a press drive motor 10, a press screw 11 and a press transmission frame 12. The press drive motor 10 drives the press screw 11 to rotate. The press screw 11 is rotatably assembled on the moving platform 3 through a bearing mounting seat 13. The press transmission frame 12 is slidably assembled on the moving platform 3. The press transmission frame 12 is threadedly connected to the press screw 11. The press screw 11 rotates back and forth, driving the press transmission frame 12 to reciprocate on the moving platform 3. The press drive assembly 9 has a simple structure and stable operation. When driving the press plate 8 to extend and retract, it is smoother and more stable. Compared with the cylinder method, it has less noise, smoother operation, and adjustable extension speed.

[0032] Furthermore, in order to facilitate the layout, the press drive motor 10 and the press screw 11 are connected through a synchronous belt assembly 15.

[0033] As an example of this embodiment, the material pressing drive assembly 9 can be implemented by a cylinder.

[0034] As an example of this embodiment, the number of the pressing plates 8 is the same as the number of the pushing rods 6, and both are fixedly assembled on the pressing transmission frame 12. The pushing rod assembly 7 includes four pushing rods 6, which are arranged on the moving platform 3 in parallel and at intervals.

[0035] While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the claims.
