Description

Technical Field

[0001] The utility model relates to the technical field of pallet recycling, in particular to a fully automatic waste recycling device for a plastic pallet with a steel pipe. Background Art

[0002] Pallets are usually used to place workpiece blanks in workshops, which facilitates the stacking of workpieces and the loading and unloading of forklifts. They are widely used in various factories today.

[0003] At present, pallets are mainly divided into wooden pallets, metal pallets and plastic pallets, which have different characteristics and are used in different scenarios. Among them, plastic pallets are light in texture and easy to place, so they are used more and more in modern factories. However, they also have the disadvantage of relatively low strength. In order to improve the limitations of plastic pallets, some manufacturers have introduced a solution to add steel pipes (also called steel beams) to plastic pallets to improve the strength of the pallets, so that they can have a higher load capacity. Specifically, a small amount of steel pipes are directly inserted into the plastic pallet, which will not increase the weight of the plastic pallet itself, but also improve the strength of the plastic pallet.

[0004] Since current pallets generally need to be inspected after a certain period of use, they need to be discarded if they can no longer be used, or if the pallet is damaged, it also needs to be scrapped.

[0005] Since the above-mentioned plastic pallets with steel pipes need to be processed after the steel pipes are extracted before the subsequent process can be carried out, but the steel pipes are currently mainly removed by manpower, which is very troublesome. Therefore, the present application proposes a fully automatic waste recovery device that can fully automatically remove steel beams from the pallet. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1:

[0030] See also Figure 1-3 The utility model provides the following technical solutions: a fully automatic waste recycling device for plastic pallets with steel pipes, comprising a conveying unit 1 for driving the pallet to move, and a positioning unit 2, a cutting unit 3 and a steel beam taking unit 4 arranged beside the conveying unit 1; the positioning unit 2 is used to clamp the pallet; the cutting unit 3 is used to cut the plastic pallet to expose the steel beam in the pallet; the steel beam taking unit 4 is used to take the steel beam out of the pallet.

[0031] As an optional implementation scheme of the utility model, the conveying unit 1 drives the pallet to the positioning unit 2, and the positioning unit 2 clamps and positions the pallet in multiple directions to prevent the pallet from shifting during cutting and causing the process of removing the steel beam to be unable to proceed. After positioning, the cutting unit 3 can cut the plastic pallet near the steel beam, so that the surface of the steel beam can be exposed, so that the steel beam removal unit 4 can smoothly remove the steel beam.

[0032] Through the above structure, it is possible to fully automatically remove the steel beams from the pallet, so that the discarded plastic pallets can be smoothly scrapped, and the steel beams therein can be recycled. The whole process does not require human participation, which can greatly save labor costs.

[0033] like Figure 1-3 As shown, the conveying unit 1 includes a bracket 11, a supporting component 12 rotatably connected to the bracket 11, and a power module for driving the supporting component 12 to rotate.

[0034] As an optional implementation scheme of the utility model, the pallet is horizontally placed on the support component 12, and the support component 12 is driven to rotate by the power module so that the pallet can smoothly enter each process. Among them, the support component 12 includes but is not limited to an electric roller, a conveyor belt, etc., and the power module includes but is not limited to a stepper motor or a servo motor, etc. Since the entire conveying unit 1 is an existing technology that has been widely used in various scenarios in the market, this technical solution will not be described in detail.

[0035] like Figure 1 As shown, the support member 12 comprises a roller.

[0036] As an optional implementation scheme of the utility model, multiple rollers are driven by a synchronous belt so that all rollers can rotate synchronously. The advantage of using rollers in this technical solution is that there are gaps between all adjacent rollers, which facilitates the subsequent advance and stop positioning mechanism 22 to extend from the gaps between the rollers so as to block and position the tray in the forward direction.

[0037] like Figure 1-3 As shown, a positioning plate 13 is provided on the bracket 11 and on one side of the supporting component 12, and the positioning unit 2 includes a clamping mechanism 21, an advance and stop positioning mechanism 22 and a lateral pushing mechanism 23;

[0038] The clamping mechanism 21 includes a first cylinder 211 and a first push plate 212 connected to the ejection end of the first cylinder 211. The first cylinder 211 is fixedly connected to the bracket 11. The ejection direction of the first cylinder 211 is downward and perpendicular to the conveying plane of the support component 12.

[0039] The stop-and-go positioning mechanism 22 includes a second cylinder 221 and a second push plate 222 connected to the ejection end of the second cylinder 221. The second push plate 222 is L-shaped. The second cylinder 221 is fixedly connected to the bracket 11 and is located below the support component 12. The ejection direction of the second cylinder 221 is upward and perpendicular to the conveying plane of the support component 12.

[0040] The lateral pushing mechanism 23 includes a third cylinder 231 and a third pushing plate 232 connected to the ejection end of the third cylinder 231 . The third cylinder 231 is fixedly connected to a side of the bracket 11 away from the positioning plate 13 . The ejection direction of the third cylinder 231 is perpendicular to the plane of the positioning plate 13 .

[0041] As an optional implementation scheme of the utility model, when the tray is driven to the positioning unit 2 by the supporting component 12, the lateral pushing mechanism 23 operates first, pushing the tray to the side close to the positioning plate 13 and making the edge of the tray contact the positioning plate 13, and then the positioning mechanism 22 extends from the bottom of the supporting component 12 to block the tray from the forward direction of the tray, and the clamping mechanism 21 clamps and positions the tray from above the tray.

[0042] like Figure 2 As shown, the cutting unit 3 comprises:

[0043] A cutter 31, the cutter 31 includes but is not limited to a cutting wheel and a laser cutter 31;

[0044] The robot arm 32 is disposed on the bracket 11 , and the cutter 31 is disposed on the robot arm 32 .

[0045] As an optional implementation scheme of the utility model, the cutter 31 in the technical scheme preferably adopts a laser cutter 31. Technical personnel in this field can also use a cutting wheel combined with a pressure sensor to ensure that the steel beam is not damaged.

[0046] After the pallet is positioned, the robot 32 drives the cutter 31 to move so that the cutter 31 can finally align with the end of the steel beam on the pallet. During cutting, the robot 32 drives the cutter 31 to cut off the plastic at the end of the steel beam, finally exposing the end of the steel beam completely, ensuring that the subsequent steel beam removal unit can clamp the steel beam and thus complete the pulling out or ejecting of the steel beam.

[0047] Furthermore, since the plastic pallet is placed on the roller, the cutter 31 may be blocked by the roller when cutting under the steel beam. Therefore, after the positioning unit 2 positions the pallet, the steel beam should be in the gap of the roller, and the roller gap here should at least allow the cutter 31 to move between the rollers from both sides of the steel beam to ensure that the plastic at the end of the steel beam can be cut off.

[0048] Furthermore, it also includes a punching mechanism, including a fifth cylinder and a punching knife. The punching knife is annular and matches the shape of the groove in the tray for placing the steel beam. The punching knife is driven by the fifth cylinder to directly punch the plastic around the steel beam, so that when the punching knife is retracted, the plastic in the length direction of the steel beam is directly cut off, which is equivalent to cutting off the position of the end cover used to block the length direction of the steel beam. Therefore, the steel beam can be directly ejected by the steel beam removal unit 4 in Example 2.

[0049] like Figure 1-3 As shown, the steel beam taking unit 4 includes a mechanical arm 41 and a mechanical claw 42 movably connected to the mechanical arm 41 , and the mechanical arm 41 is arranged on the bracket 11 .

[0050] As an optional implementation scheme of the utility model, the mechanical claw 42 is used to clamp the steel beam, and the mechanical arm 41 is used to drive the mechanical claw 42 to move so that the steel beam is pulled out by the mechanical claw 42. Both the mechanical claw 42 and the mechanical arm 41 can adopt the existing mature technologies on the market. Those skilled in the art can also use the method of clamping the inner wall of the steel beam from the hollow interior of the steel beam to achieve the removal of the steel beam.

[0051] Embodiment 2:

[0052] Specifically, the steel beam unit 4 includes a fourth cylinder and a fourth push plate connected to the ejection end of the fourth cylinder. The fourth cylinder is fixedly connected to the bracket 11 , and the ejection direction of the fourth cylinder is perpendicular to the moving direction of the pallet on the conveying unit 1 .

[0053] As another optional implementation scheme of the utility model, after the end of the steel beam is exposed, it is directly extended through the fourth cylinder, so as to push the steel beam out of the pallet.

[0054] Among them, this technical solution uses the method of ejecting the steel beam to achieve the separation of the plastic pallet and the steel beam, so at least two groups of cutting units 3 must be set and located on both sides of the width direction of the conveying unit 1, and at least the plastics at both ends of the steel beam in the length direction must be cut off respectively.

[0055] Embodiment 3:

[0056] Specifically, this embodiment adopts the method of combining embodiment 1 with embodiment 2, that is, the technical solutions of pulling out the steel beam and clamping the steel beam are adopted at the same time. The advantage of this method is that the process of removing the steel beam can be completed more smoothly.

[0057] The working principle and use process of the utility model are as follows: the conveying unit 1 drives the pallet to the positioning unit 2, and the positioning unit 2 clamps and positions the pallet in multiple directions to prevent the pallet from shifting during cutting and causing the process of taking the steel beam to be unable to proceed. After positioning, the cutting unit 3 can cut the plastic pallet near the steel beam, so that the surface of the steel beam can be exposed, so that the steel beam taking unit 4 can smoothly take out the steel beam.

[0058] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
