Description

Technical Field

[0001] The utility model relates to the technical field of material containers, in particular to a steel pipe silo used for assembling 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 increasingly used 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 solutions to add steel beams to plastic pallets to increase 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] At present, the steel pipe is mainly placed in the steel pipe insertion device by the manipulator by clamping the steel pipe, and then the steel pipe is pushed into the plastic pallet, or the steel pipe is directly inserted into the plastic pallet by the manipulator. However, no matter which method is used, after the manipulator takes the steel pipe in the silo, it is necessary to locate the steel pipe that needs to be clamped next time in the silo. At present, the manipulator mainly relies on visual positioning to provide the steel pipe positioning for the manipulator, but this also makes the time consumption different each time for assembly, resulting in reduced assembly production efficiency.

[0005] Therefore, in order to improve the assembly efficiency of plastic pallets, the present application proposes a steel pipe silo for assembling plastic pallets with steel pipes, which can provide an accurate clamping position for a robot when assembling the plastic pallet. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a steel pipe silo for assembling plastic pallets with steel pipes, which solves the problem that the efficiency of plastic pallet assembly production is not high enough due to the current method of relying on visual positioning.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel pipe silo for assembling a steel pipe plastic pallet, comprising a base frame and a chassis slidably connected to the base frame, the side walls of the base frame are also rotatably connected with a chain, the two sides of the chassis are fixedly connected to the chain, and the upper part of the side walls of the base frame are also respectively provided with a lateral material straightening mechanism, a transverse material straightening mechanism and a lifting limit structure.

[0008] Preferably, the base frame is also provided with a motor for driving each chain to rotate, and also includes a control module, and the output end of the control module is electrically connected to the input end of the motor.

[0009] Preferably, the lateral material-forming mechanism and the transverse material-forming mechanism both comprise a cylinder body and a material-forming plate fixedly connected to the ejection end of the cylinder body, and the moving directions of the two material-forming plates are perpendicular to each other and are both in a plane parallel to the chassis.

[0010] Preferably, in the transverse material-forming mechanism, the material-forming plate is fixedly connected to the ejection end of the cylinder body through a pressure sensor, the output end of the pressure sensor is electrically connected to the input end of the cylinder body, and the cylinder body is normally open for low-pressure ejection.

[0011] Preferably, the lifting limit structure comprises a limit block having a trapezoidal axial section.

[0012] Preferably, the lifting and limiting structure includes two horizontally arranged infrared ranging sensors, and both are arranged on a side of the frame away from the transverse material sorting mechanism.

[0013] Preferably, the vertical height of the lifting and limiting structure is higher than the vertical height of the bottom of the material-forming plate in the transverse material-forming mechanism, and the height difference does not exceed the height of one steel pipe.

[0014] Preferably, casters are also provided at the bottom of the base frame.

[0015] Compared with the prior art, the utility model provides a steel pipe silo for assembling a plastic pallet with a steel pipe, which has the following beneficial effects:

[0016] The steel pipe silo used for assembling plastic pallets with steel pipes can not only organize the materials so that the steel pipes are stacked neatly, but also provide an accurate clamping position for the robot when assembling the plastic pallet, thereby ensuring a smooth assembly process of the plastic pallet. At the same time, since the robot takes away the same position each time, the time required for visual positioning or moving to different positions is reduced, thereby improving the assembly efficiency of the plastic pallet.

DETAILED DESCRIPTION

[0020] 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.

[0021] The steel tubes in the existing plastic pallets are mainly square tubes and round tubes. The steel tubes used in the present technical solution are all square tubes, and the square tubes are clamped at both axial ends by a robot and then inserted into the pallet from the side of the pallet.

[0022] See also Figure 1 The utility model provides the following technical solutions: a steel pipe silo for assembling a plastic pallet with steel pipes, comprising a base frame 1 and a chassis 2 slidably connected to the base frame 1, a chain 3 is rotatably connected to the side wall of the base frame 1, both sides of the chassis 2 are fixedly connected to the chain 3, and the upper part of the side wall of the base frame 1 is also provided with a lateral material organization mechanism 4, a transverse material organization mechanism 5 and a lifting limit structure 6.

[0023] As an optional implementation scheme of the utility model, the side walls of the base frame 1 are composed of a plurality of baffles to prevent the steel pipes from scattering during the movement of the base frame 1; and, after deducting the necessary sliding gap, the spacing between the baffles on both sides is an integer multiple of the width of the steel pipe, which helps to place the steel pipes in parallel.

[0024] After the operator has filled the silo with steel pipes, the lateral material-aligning mechanism 4 applies pressure to the axial ends of all the steel pipes so that all the steel pipes are aligned axially, and the lateral material-aligning mechanism 4 after pressurization maintains the pressurizing action to avoid the steel pipes from being offset axially and misaligned during the movement process;

[0025] When it is necessary to assemble the steel pipes onto the plastic pallet, the base frame 1 is moved to the vicinity of the robot and fixed in position, and the two lateral material-leveling mechanisms 4 are separated from the steel pipes, so that the clamping mechanism of the robot has enough space to clamp the axial end of the steel pipe; then the chassis 2 is raised by the rotation of the chain 3, and the steel pipe is positioned in the vertical direction under the action of the lifting limit mechanism; the transverse material-leveling mechanism 5 starts to run, and pushes the topmost steel pipe to the other side of the base frame 1 to ensure that the topmost steel pipe in contact with the side wall of the base frame 1 is accurately positioned, and after the steel pipe here is taken out, the transverse material-leveling mechanism 5 continues to run to complete the positioning of the next steel pipe; when all the topmost steel pipes are taken away by the robot, the transverse material-leveling mechanism 5 is reset, and the chain 3 continues to rotate to raise the chassis 2 until all the steel pipes are taken out or the target assembly quantity is completed.

[0026] Through the above structure, a method is constructed that can not only organize the materials so that the steel pipes are stacked neatly, but also provide an accurate clamping position for the robot when assembling the plastic pallet, thereby ensuring the smooth assembly process of the plastic pallet. At the same time, since the robot takes away the same position each time, the time required for visual positioning or moving to different positions is reduced, thereby improving the assembly efficiency of the plastic pallet.

[0027] like Figure 1-2 As shown, the base frame 1 is also provided with a motor 7 for driving each chain 3 to rotate, and also includes a control module 8, and the output end of the control module 8 is electrically connected to the input end of the motor 7.

[0028] As an optional implementation scheme of the utility model, the operation of the motor 7 is controlled by the control module 8 to achieve automatic lifting after the steel pipes on each layer are fully placed or all taken away.

[0029] Among them, the motor 7 is connected to the chain 3 through a synchronization mechanism, and the synchronization mechanism specifically includes a sprocket rotatably connected to the upper and bottom of the base frame 1, an axle rod at the bottom of the base frame 1 for installing the sprocket, and a transmission member connected between the axle rod and the output shaft of the motor 7. When the motor 7 is running, the two transmission members are driven to rotate synchronously, so that the chains 3 on both sides of the base frame 1 run synchronously to ensure that the lifting and lowering of the chassis 2 can always remain balanced.

[0030] like Figure 1 As shown, the lateral material-forming mechanism 4 and the transverse material-forming mechanism 5 both include a cylinder body 9 and a material-forming plate 10 fixedly connected to the ejection end of the cylinder body 9 . The moving directions of the two material-forming plates 10 are perpendicular to each other and are both in a plane parallel to the chassis 2 .

[0031] As an optional embodiment of the present invention, the cylinder body 9 includes one or both of a pneumatic cylinder and a hydraulic cylinder. Since the lateral material-forming mechanism 4 driving the steel pipe shaft section needs to bear more load during operation, it is preferred that the lateral material-forming mechanism 5 adopts a pneumatic cylinder to have a faster response speed to adapt to the environment where the steel pipe needs to be pushed frequently, while the lateral material-forming mechanism 4 adopts a hydraulic cylinder to have a higher load to adapt to pushing the shaft ends of all steel pipes.

[0032] Furthermore, the transverse material-straightening mechanism 5 can also adopt a scissor frame structure to realize the arrangement of steel pipes. It has a long stroke and can be reduced to a very small volume, which is convenient for installation on the silo.

[0033] like Figure 2 As shown, in the transverse material distributing mechanism 5, the material distributing plate 10 is fixedly connected to the ejection end of the cylinder 9 through the pressure sensor 11, the output end of the pressure sensor 11 is electrically connected to the input end of the cylinder 9, and the cylinder 9 is normally open for low-pressure ejection.

[0034] As an optional implementation scheme of the present invention, the pressure sensor 11 can detect the resistance encountered by the cylinder body 9 during the ejection process, that is, when the pressure sensor 11 detects that the pressure reaches the target value, it means that the steel pipe has been ejected into place. At this time, the output electrical signal controls the cylinder body 9 to return a certain distance, thereby preventing the whole material plate 10 from continuously pressing the steel pipe, causing the robot to have difficulty in overcoming the large resistance and smoothly removing the steel pipe. Of course, if a robot that clamps the side of the steel pipe axis is used, it can also be used. Then the cylinder body 9 is ejected again under low pressure, and the remaining steel pipes continue to be pushed into place after the positioned steel pipes are removed.

[0035] like Figure 1 As shown, the lifting and limiting structure 6 includes a limiting block 12 whose axial section is a trapezoid.

[0036] As an optional implementation scheme of the present invention, the limit block 12 is used to limit the rising height of the chassis 2, especially to prevent the height position of the chassis 2 from being inaccurately positioned, thereby affecting the smooth operation of the transverse material organization mechanism 5, to ensure the smooth arrangement of the transverse material organization mechanism 5 when adding steel pipes to the silo, and to ensure that the transverse material organization mechanism 5 can push the steel pipes to a position where the robot can take them away smoothly when assembling plastic pallets. The trapezoidal shape of the limit block 12 is to make the process of placing the steel pipes into the silo smoother under the condition of being limitable.

[0037] Furthermore, a roller may be provided at the bottom of the limit block 12 to reduce the frictional resistance from the limit block 12 when the steel pipe is pushed, thereby preventing the steel pipe from tipping over and affecting the subsequent assembly of the plastic pallet.

[0038] like Figure 1 As shown, the lifting and limiting structure 6 includes two horizontally arranged infrared distance measuring sensors 13, and both are arranged on a side of the frame away from the horizontal material sorting mechanism 5.

[0039] As an optional implementation scheme of the utility model, when assembling a plastic pallet, after the steel pipes on the top layer are taken out, two infrared ranging sensors 13 detect whether there are any remaining steel pipes on the top layer, that is, if both sensors detect that there are, or the infrared ranging sensor 13 far away from the horizontal material sorting mechanism 5 detects that there are no steel pipes, and the other sensor detects that there are remaining steel pipes on the top layer, when both sensors detect that there are no steel pipes on the top layer, then the motor 7 is controlled to operate to raise the chassis 2.

[0040] Therefore, compared with the method of using the limit block 12, the method of using the infrared distance measuring sensor 13 further avoids the obstruction when the steel pipe is loaded into the silo and when the material is being assembled, and is conducive to the automatic operation of the material assembly.

[0041] like Figure 1As shown, the vertical height of the lifting and limiting structure 6 is higher than the vertical height of the bottom of the material-forming plate 10 in the horizontal material-forming mechanism 5, and the height difference does not exceed the height of a steel pipe.

[0042] As an optional implementation scheme of the utility model, the accuracy of the height limit of the chassis 2 when it rises is guaranteed, ensuring that the horizontal material sorting mechanism 5 can be aligned with the uppermost steel pipe for sorting.

[0043] like Figure 1 As shown, casters 14 are also provided at the bottom of the base frame 1 .

[0044] As an optional implementation scheme of the present utility model, the caster 14 can be a universal wheel or a tire with a drive system to facilitate the movement of the silo.

[0045] The working principle and use process of the utility model are as follows: after the operator puts the steel pipes into the silo, the lateral material-aligning mechanism 4 pressurizes the axial ends of all the steel pipes so that all the steel pipes are axially aligned, and the pressurized lateral material-aligning mechanism 4 keeps the pressurizing action to avoid the steel pipes being offset in the axial direction and unable to align during the movement;

[0046] When it is necessary to assemble the steel pipes onto the plastic pallet, the base frame 1 is moved to the vicinity of the robot and fixed in position, and the two lateral material-leveling mechanisms 4 are separated from the steel pipes, so that the clamping mechanism of the robot has enough space to clamp the axial end of the steel pipe; then the chassis 2 is raised by the rotation of the chain 3, and the steel pipe is positioned in the vertical direction under the action of the lifting limit mechanism; the transverse material-leveling mechanism 5 starts to run, and pushes the topmost steel pipe to the other side of the base frame 1 to ensure that the topmost steel pipe in contact with the side wall of the base frame 1 is accurately positioned, and after the steel pipe here is taken out, the transverse material-leveling mechanism 5 continues to run to complete the positioning of the next steel pipe; when all the topmost steel pipes are taken away by the robot, the transverse material-leveling mechanism 5 is reset, and the chain 3 continues to rotate to raise the chassis 2 until all the steel pipes are taken out or the target assembly quantity is completed.

[0047] 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.
