DETAILED DESCRIPTION

[0038] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0039] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0040] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0041] See also Figures 1 to 10 In an embodiment of the present invention, an intelligent packaging material transfer device includes an installation box 1, a conveying frame 2, a clamping member 8, a conveying unit, a parallel connecting rod structure, a reciprocating push member, a one-way transmission member, a transfer mechanism and a gap driving mechanism.

[0042] For details, please refer to Figure 2 , Figure 3 and Fig. 9 ,include:

[0043] An installation box 1, a conveying frame 2 is provided at a side end of the installation box 1, and one end of the conveying frame 2 extends into the installation box 1, and a conveying unit is provided on the conveying frame 2;

[0044] A parallel connecting rod structure is installed in the installation box 1, the movable end of the parallel connecting rod structure is connected to a clamping member 8, and the parallel connecting rod structure is controlled by a reciprocating pusher disposed in the installation box 1 to perform reciprocating circular swing;

[0045] A transfer mechanism is arranged in the installation box 1, and a tray 18 is detachably connected to the transfer mechanism. The parallel connecting rod structure is connected to the transfer structure through a one-way transmission member to control the height of the packaging material to remain unchanged each time it falls;

[0046] The intermittent driving mechanism is arranged in the installation box 1 and is respectively connected to the reciprocating pushing member and the conveying unit.

[0047] In detail, in this embodiment, the intelligent packaging material transfer device of the present invention is adopted. When in use, after the conveying unit conveys the packaging material to be transferred to the bottom of the clamping member 8, the clamping member 8 performs a clamping action on the packaging material. At this time, under the drive of the gap driving mechanism, the conveying unit stops the conveying work, and the reciprocating pusher drives the parallel connecting rod structure to swing back and forth, so that the parallel connecting rod structure drives the clamping member 8 to move from the top of the conveying unit to the upper end of the transfer mechanism, and the clamping member 8 stops clamping the packaging material, so that the packaging material falls onto the transfer mechanism under the action of gravity. When the parallel connecting rod structure is reset, under the action of the one-way transmission member, the receiving position of the packaging material on the transfer mechanism is driven to change, so that the height to which the packaging material descends each time the clamping member 8 is dropped remains consistent, avoiding damage to the stacked packaging materials while making room for the next stacking of packaging materials. The movement trajectory of the parallel connecting rod structure along the arc line further reduces the friction between the packaging materials and the conveying unit after clamping, which can prevent scratches, wear or other physical damage to the packaging materials due to excessive friction during movement, thereby improving transportation efficiency and safety, and reducing energy consumption and maintenance costs.

[0048] Preferably, the conveying unit comprises at least two rollers 4 rotatably mounted on the conveying frame 2 , and a conveying belt 3 is arranged between the two rollers 4 .

[0049] Preferably, a plurality of grooves are provided on the conveyor belt 3, and the main purpose of the grooves is to enable the packaging materials to be evenly distributed on the conveyor belt 3, to ensure the stability and consistency of the packaging materials during transportation, and to reduce the friction between the packaging materials and the conveyor belt 3, thereby avoiding wear and damage of the packaging materials due to friction.

[0050] As a further solution of the present invention, please refer to Figure 4 and Figure 7 The parallel connecting rod structure includes a first connecting rod 5 and a second connecting rod 6 which are parallel to each other, and the first connecting rod 5 and the second connecting rod 6 are rotatably connected to the inner side of the installation box 1 through a first rotating shaft 9 and a second rotating shaft 10 respectively;

[0051] It also includes a connecting plate 7 , and one end of the first connecting rod 5 and the second connecting rod 6 away from the first rotating shaft 9 and the second rotating shaft 10 is rotatably connected to the connecting plate 7 , and the bottom of the connecting plate 7 is fixed to the clamping member 8 .

[0052] The parallel connecting rod structure is used to horizontally transfer the clamping member 8, which can effectively ensure the reliability of the transmission process. Under the action of the reciprocating push member, the first connecting rod 5 is driven to move back and forth, causing the first connecting rod 5 to swing. Since the positions of the first rotating shaft 9 and the second rotating shaft 10 are fixed, the first connecting rod 5 and the second connecting rod 6 respectively complete a single circular reciprocating swing with the first rotating shaft 9 and the second rotating shaft 10 as the center, so that the connecting plate 7 is always displaced in a horizontal state, avoiding the position of the clamping member 8 from tilting when it is delivered, and further improving the on-time delivery of the packaging materials on the transfer mechanism.

[0053] As a further solution of the present invention, please refer to Figure 5 The one-way transmission member includes a support shaft 12 rotatably mounted in the mounting box 1, a sleeve 11 is slidably connected to the support shaft 12, a plurality of second latch teeth are provided on the sleeve 11, and the second latch teeth are adapted to mesh with the first latch teeth provided on the first rotating shaft 9;

[0054] It also includes a spring 13 , which is sleeved on the support shaft 12 , with one end of the spring 13 fixedly connected to the support shaft 12 , and the other end of the spring 13 fixedly connected to the sleeve 11 .

[0055] Preferably, at least one set of limiting sliding grooves 1201 is formed on the support shaft 12 , and a limiting sliding block 1101 slidably matched with the limiting sliding grooves 1201 is formed on the sleeve 11 .

[0056] Preferably, the second latching tooth is arranged in a right-angled triangle structure on one side facing the first latching tooth, and the inclined surface of the first latching tooth abuts against the inclined surface of the second latching tooth.

[0057] When the first connecting rod 5 deflects toward one end of the transfer mechanism, it drives the first rotating shaft 9 to rotate clockwise, so that the inclined surface on the first latch tooth tilts toward the inclined surface on the second latch tooth. Under the limiting action of the limiting slide groove 1201 and the limiting slider 1101, the sleeve 11 moves downward along the axial direction of the support shaft 12 and squeezes the spring 13, so that the spring 13 reserves elastic potential energy. At this time, the movement of the sleeve 11 has no effect on the support shaft 12. When the inclined surface on the first latch tooth rotates to disengage from the inclined surface on the second latch tooth, under the action of the spring 13, the second latch tooth is again inserted into the plug-in groove formed by the two first latch teeth to achieve the sleeve 11 giving way to the rotation of the first rotating shaft 9.

[0058] Among them, when the first connecting rod 5 is reset, it drives the first rotating shaft 9 to rotate counterclockwise. At this time, the right-angled surface on the first latch tooth generates an extrusion force on the right-angled surface on the second latch tooth, so that the sleeve 11 rotates with the rotation of the first rotating shaft 9 to realize the rotation requirement of the support shaft 12, ensuring that the receiving position of the rotating mechanism changes when the clamping member 8 is reset.

[0059] As a further solution of the present invention, please refer to Figure 6 The transfer mechanism includes a screw rod 15 rotatably connected to the bottom of the installation box 1 and a guide rod 17 fixedly installed in the installation box 1, a receiving plate 16 is arranged between the screw rod 15 and the guide rod 17, and a first sleeve 1601 and a second sleeve 1602 are respectively arranged at both ends of the receiving plate 16, the first sleeve 1601 is threadedly connected to the screw rod 15, the second sleeve 1602 is slidably connected to the guide rod 17, and the receiving plate 16 is detachably connected to the tray 18.

[0060] When the support shaft 12 rotates, the first belt 14 acts to realize the rotation of the screw rod 15, and the transmission ratio between the support shaft 12 and the screw rod 15 must be greater than 1. It is necessary to ensure that the height of the pallet 18 descends each time is the same as the height of the packaging material, so that the height of the packaging material does not change each time the clamp 8 is dropped. When the pallet 18 descends to a certain height, after the packaging material on the pallet 18 is loaded, a forklift is inserted into the gap between the pallet 18 and the receiving plate 16, and the pallet 18 and the receiving plate 16 are controlled to be separated and transported to other areas.

[0061] As a further solution of the present invention, please refer to Figure 7 The reciprocating pusher includes a connecting shaft 29 rotatably connected to the top of the inner side of the installation box 1, a transmission plate 30 is fixedly mounted on the connecting shaft 29, and a convex column 3001 is provided at an eccentric position of the transmission plate 30;

[0062] It also includes a movable plate 31, which is slidably connected to the inner top of the installation box 1 through a limiting rod 3102, and a limiting groove 3101 is formed on the movable plate 31 to slide with the boss 3001, and the end of the movable plate 31 away from the transmission plate 30 is fixedly connected to the first connecting rod 5.

[0063] The intermittent drive structure includes a drive shaft 19 rotatably mounted in the installation box 1, the drive shaft 19 is driven to rotate by a motor 22 fixedly mounted in the installation box 1, and a driving wheel 24 is provided on the drive shaft 19;

[0064] It also includes a first transmission shaft 20 and a second transmission shaft 21 rotatably installed in the installation box 1, and the first transmission shaft 20 and the second transmission shaft 21 are respectively provided with a first driven wheel 23 and a second driven wheel 25 that rotate with the driving wheel 24. The first transmission shaft 20 is rotatably connected to a rotating shaft 27 rotatably installed in the installation box 1 through a second belt 26, and the rotating shaft 27 is rotatably connected to the connecting shaft 29 through a first bevel gear set 28. The second transmission shaft 21 is rotatably connected to a third transmission shaft 33 rotatably set in the installation box 1 through a second bevel gear set 32, and the third transmission shaft 33 is rotatably connected to one of the rollers 4 through a third belt 34.

[0065] Specifically, by starting the motor 22, the output shaft of the motor 22 is fixedly connected to the drive shaft 19. When the drive shaft 19 rotates, the driving wheel 24 is driven to rotate synchronously. Due to the gap rotation characteristics of the driving wheel 24 and the first driven wheel 23 and the second driven wheel 25, the gap rotation of the first transmission shaft 20 and the second transmission shaft 21 is realized. When the first transmission shaft 20 rotates, under the action of the second belt 26, the intermediate shaft 27 is driven to rotate. When the intermediate shaft 27 rotates, under the action of the first bevel gear set 28, the connecting shaft 29 is driven to rotate. When the connecting shaft 29 rotates, the transmission plate 30 is driven to rotate synchronously. At this time, the boss 3001 moves in a circle with the connecting shaft 29 as the center. When the convex column 3001 moves, it squeezes the movable plate 31. Under the action of the limiting rod 3102, the movable plate 31 can move back and forth relative to the installation box 1, thereby driving the first connecting rod 5 to reciprocate. When the second transmission shaft 21 rotates, under the action of the second bevel gear set 32, the third transmission shaft 33 is driven to rotate. When the third transmission shaft 33 rotates, under the action of the third belt 34, one of the rollers 4 is driven to rotate, thereby realizing the gap work between the conveying unit and the parallel connecting rod structure, avoiding interference between the conveying and displacement work of the packaging materials, and further increasing the transportation efficiency of the packaging materials.

[0066] It is worth noting that a reducer is provided between the motor 22 and the driving shaft 19 to ensure that when the conveying unit stops working, a buffer time is provided for the clamping member 8 to clamp the packaging material.

[0067] An intelligent packaging material transfer method, using any one of the intelligent packaging material transfer devices described above, comprises the following steps:

[0068] Step 1: After the gap driving mechanism drives the conveying unit to convey the packaging material to be transferred to the lower end of the clamping member 8, the clamping member 8 clamps the packaging material, and the conveying work is stopped at this time;

[0069] Step 2: When the gap driving mechanism drives the reciprocating pusher to work, it drives the parallel connecting rod structure to perform circular swing, and when it swings to the top of the transfer mechanism, the clamping member 8 is released, and after the packaging material falls onto the transfer structure, the parallel connecting rod structure and the clamping member 8 are reset to prepare for the next clamping and swinging work;

[0070] Step three: while the parallel link structure is reset, the one-way transmission member changes the load-bearing height of the transfer mechanism so that the height of the packaging material remains unchanged each time it falls.

[0071] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0072] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
