Technical Field

[0001] This invention relates to the field of container processing equipment, and more particularly to assembly devices. Background Technology

[0002] During the current container processing and assembly, the top side beams of the container are bent horizontally inwards. Before the top plate is welded to the container, the bent top side beams need to be straightened manually using pry bars. This makes container assembly difficult and inefficient.

[0003] To address these issues, the present invention provides an assembly apparatus that at least partially solves the problems in the prior art. Summary of the Invention

[0004] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. The summary section of this invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

The assembly device includes: a first longitudinal beam, both ends of which are provided with positioning planes for abutting against the outer side of the top corner piece of the container from the side of the container to be assembled; a first electromagnet, fixedly mounted on the first longitudinal beam, with a first adsorption side of the first electromagnet closer to the interior of the container than the positioning planes, and the first electromagnet located between the two positioning planes in the extending direction of the first longitudinal beam, the first adsorption side being used to adsorb the outer side of the top corner piece of the container; and a second electromagnet, located between the two positioning planes in the extending direction of the first longitudinal beam, the second electromagnet being movably mounted on the first longitudinal beam for adsorbing and straightening the top corner piece of the container.

[0006] According to the assembly device of the present invention, after the first longitudinal beam is moved so that the positioning plane of the first longitudinal beam abuts against the outer side of the top corner piece, the second electromagnet is moved so that the second electromagnet attracts the outer side of the top side beam. Then, the second electromagnet attracting the top side beam is moved in a direction away from the container, so that the top side beam can be straightened. The operation of straightening the top side beam is simple and the work efficiency is high.

However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions is exaggerated, and the same reference numerals are used to denote the same elements, and therefore their description will be omitted.

[0031] A preferred embodiment of the present invention provides an assembly device. The assembly device is used to secure the top plate of container 110 to the top side beam.

[0032] like Figures 1 to 4 As shown, the assembly device includes a longitudinal beam assembly. The longitudinal beam assembly is located on the side of the container 110 to be assembled. The longitudinal beam assembly includes a first frame and a first longitudinal beam 120. The first longitudinal beam 120 extends along the length of the container 110 to be assembled. Positioning planes are provided at both ends of the first longitudinal beam 120, facing the side of the container 110 to be assembled. The positioning planes are used to abut against the sides of the corner pieces of the container 110 to be assembled.

[0033] The longitudinal beam assembly includes a transverse hydraulic cylinder, a transverse slider, and a transverse slide. The transverse hydraulic cylinder is mounted on the first frame. The cylinder rod of the transverse hydraulic cylinder is telescopic along the width direction of the container 110 to be assembled. The transverse slide extends along the width direction of the container 110 to be assembled. The transverse slider is connected to the first longitudinal beam 120. The transverse slider is also connected to the free end of the cylinder rod of the transverse hydraulic cylinder. Thus, the first longitudinal beam 120 is mounted on the first frame via the transverse slider. The transverse hydraulic cylinder drives the first longitudinal beam 120 to move along the width direction of the container 110 to be assembled, so that the positioning plane abuts against or moves away from the top corner piece of the container to be assembled.

[0034] The longitudinal beam assembly also includes a first electromagnet 130. The first electromagnet 130 is fixedly connected to the first longitudinal beam 120. The first electromagnet 130 is provided with a first adsorption side. In the width direction of the container to be assembled, the first adsorption side faces the interior space of the container 110 to be assembled. The first adsorption side is correspondingly provided with the top side beam of the container 110 to be assembled. The first adsorption side is used to adsorb the outer side of the top side beam of the container 110 to be assembled.

[0035] In the width direction of the container 110 to be assembled, the first adsorption side is closer to the interior space of the container 110 than the aforementioned positioning plane. The distance between the first adsorption side and the positioning plane in the width direction of the container 110 to be assembled is a preset distance. This preset distance is approximately the same as the distance between the outer side of the top side beam and the outer side of the top corner piece of the standard container 110.

[0036] Preferably, the preset distance is in the range of 3mm to 4mm.

[0037] Along the extending direction of the first longitudinal beam 120, the longitudinal beam assembly includes a plurality of first electromagnets 130. The plurality of first electromagnets 130 are spaced apart along the extending direction of the first longitudinal beam 120.

[0038] The longitudinal beam assembly also includes a second electromagnet 140. The second attraction side of the second electromagnet 140 is used to attract the outer surface of the top side beam of the container 110 to be assembled. The second electromagnet 140 is movably mounted on the first longitudinal beam 120 along the width direction of the container 110 to be assembled. Thus, by attracting the outer surface of the top side beam with the second attraction side of the second electromagnet 140, and then moving the second electromagnet 140 along the width direction of the container 110 to be assembled away from the container 110, a bent top side beam can be straightened.

[0039] Preferably, the longitudinal beam assembly further includes a first cylinder. The first cylinder is connected to a second electromagnet 140. Thus, the first cylinder drives the second electromagnet 140 to move in the width direction of the container 110 to be assembled. Consequently, the movement of the second electromagnet 140 in the width direction of the container 110 to be assembled is stable.

[0040] In the extending direction of the first longitudinal beam 120, the second electromagnet 140 is located at the middle position of the first longitudinal beam 120. Thus, in the extending direction of the first longitudinal beam 120, the second electromagnet 140 is located approximately at the middle position of the top side beam. The second electromagnet 140 attracts the top side beam at approximately the middle position. The second electromagnet 140 can more effectively straighten the top side beam.

[0041] In this embodiment, the second electromagnet 140 has a straightened position. When the second electromagnet 140 is in the straightened position, its second adsorption side is approximately flush with the first adsorption side of the first electromagnet 130. When the second electromagnet 140 straightens the top side beam, it stops moving away from the container 110 to be assembled. At this time, the second electromagnet 140 and the first electromagnet 130 work together to maintain the distance between the entire outer side of the top side beam and the outer side of the top corner piece at the aforementioned preset distance.

[0042] In this embodiment, the first longitudinal beam 120 is moved in the width direction of the container 110 to be assembled so that the positioning plane of the first longitudinal beam 120 abuts against the outer side of the top corner piece. Then, the second electromagnet 140 is moved so that the second electromagnet 140 attracts the outer side of the top side beam. Then, the second electromagnet 140 attracting the top side beam is moved away from the container 110 to be assembled, so that the top side beam can be straightened. The operation of straightening the top side beam is simple and the work efficiency is high.

[0043] In this embodiment, the longitudinal beam assembly further includes a transverse guide 150 and a longitudinal guide 160. When the top plate is moved above the container 110 by a hoisting device (e.g., an overhead crane or gantry crane) and moves downwards towards the upper end of the container 110 to be assembled, the transverse guide 150 guides the movement of the top plate in the width direction (lateral direction) of the container 110 to be assembled. The longitudinal guide 160 guides the movement of the top plate in the length direction (longitudinal direction) of the container 110 to be assembled. Thus, the top plate, guided by the transverse guide 150 and the longitudinal guide 160, moves to a predetermined position at the upper end of the container 110.

[0044] The upper surfaces of the transverse guide 150 and the first longitudinal beam 120 are connected (by welding or bolting). The upper surface of the transverse guide 150 is a guide surface. The guide surface of the transverse guide 150 is inclined inward from top to bottom (towards the interior of the container 110 in the width direction of the container to be assembled). In the width direction of the container 110 to be assembled, the bottom end of the guide surface of the transverse guide 150 extends to the top side beam of the container 110 to be assembled. Thus, when the top plate moves from top to bottom towards the upper end of the container 110 to be assembled, the top plate contacts the guide surface of the transverse guide 150. Under the action of the guide surface of the transverse guide 150, the top plate slides towards the interior of the container 110 to the preset position of the top side beam in the width direction of the container 110 to be assembled. This facilitates the positioning of the top plate in the transverse direction of the container 110 to be assembled.

[0045] The longitudinal beam assembly includes two longitudinal guides 160. One longitudinal guide 160 is pivotally connected to a first end of the first longitudinal beam 120. The other longitudinal guide 160 is pivotally connected to a second end of the first longitudinal beam 120. Thus, the longitudinal guide 160 can swing horizontally about its pivot position. The longitudinal guide 160 has a first position and a second position. When the longitudinal guide 160 is in the first position, its upper surface extends along the length of the container 110 to be assembled, and its upper surface is substantially flush with the upper surface of the transverse guide 150.

[0046] When the longitudinal guide 160 is in the second position, its upper surface extends along the width direction of the container 110. At this time, the upper surface of the longitudinal guide 160 serves as a guide surface. The guide surface of the longitudinal guide 160 is inclined inward from top to bottom (towards the interior of the container 110 in the length direction of the container to be assembled). In the length direction of the container 110 to be assembled, the bottom end of the guide surface of the longitudinal guide 160 extends to the top beam of the container 110. Thus, when the top plate moves downward towards the top of the container 110 to be assembled, the top plate contacts the guide surface of the longitudinal guide 160. Under the action of the guide surface of the longitudinal guide 160, the top plate slides towards the interior of the container 110 in the length direction of the container to be assembled to a preset position on the top beam. This facilitates positioning of the top plate in the length direction of the container 110 to be assembled.

[0047] The longitudinal beam assembly also includes a first drive element. The first drive element may be a motor or a cylinder. The swinging of the longitudinal guide 160 between a first position and a second position can be driven by the first drive element.

[0048] In this embodiment, the starting position of the longitudinal guide 160 is the first position. This ensures that the longitudinal guide 160 does not affect the movement of the container 110. When the container 110 moves to the assembly station, the longitudinal guide 160 swings from the first position to the second position to guide the movement of the top plate along the length of the container 110. After the top plate of the container 110 is installed and welded at this assembly station, the longitudinal guide 160 swings from the second position to the first position so that the container can be moved out of the assembly station.

[0049] The longitudinal beam assembly also includes a second longitudinal beam 170, a pressure foot spring, and a pressure foot 180. The second longitudinal beam 170 extends along the extension direction of the first longitudinal beam 120. The second longitudinal beam 170 is pivotally connected to the first frame. Thus, the second longitudinal beam 170 can swing about its pivot position in a plane perpendicular to the extension direction of the first longitudinal beam 120. This allows the second longitudinal beam 170 to have a third position and a fourth position. The longitudinal beam assembly also includes a second drive element. The second drive element can be a motor or a cylinder. The swinging of the second longitudinal beam 170 can be driven by the second drive element.

[0050] The first end of the pressure foot spring is connected to the second longitudinal beam 170. The pressure foot 180 is connected to the second end of the pressure foot spring. When the second longitudinal beam 170 is in the first position, the pressure foot 180 is away from the top plate. When the second longitudinal beam 170 is in the second position, the pressure foot 180 presses against the top plate to prevent the flat plate from arching. When the second longitudinal beam 170 is in the second position, the pressure foot spring deforms, and the deformed pressure foot spring applies a force to the pressure foot 180, causing the pressure foot 180 to deflect towards the flat plate.

[0051] In this embodiment, the initial position of the second longitudinal beam 170 is the first position. When the top plate is placed on the top side beam of the container 110, the second longitudinal beam 170 can be swung from the first position to the second position so that the pressure foot 180 presses the top plate.

[0052] In this embodiment, the longitudinal beam assembly further includes a second frame, a height-adjusting cylinder 200, a guide sleeve, and a height guide component. The height-adjusting cylinder 200 is fixedly mounted on the second frame. The cylinder rod of the height-adjusting cylinder 200 can extend and retract along the height direction (vertical direction) of the container 110 to be assembled. The height guide component is connected to the free end of the cylinder rod. The height guide component is connected to the first frame. Thus, the height-adjusting cylinder 200 can drive the first frame to move up and down through the height guide component, thereby driving the first longitudinal beam 120 to move up and down. The guide sleeve is fixedly mounted on the second frame. The guide sleeve is fitted around the outer periphery of the height guide component. Thus, the guide sleeve guides the movement of the height guide component. In this way, the height of the first longitudinal beam 120 is adjustable. Therefore, the assembly device can be used to assemble standard containers or high cube containers (the height dimension of the high cube container is larger than the height dimension of the standard container). Preferably, the first longitudinal beam 120 can move 305mm in the height direction of the container 110.

[0053] The first longitudinal beam 120 of each longitudinal beam assembly can also be divided into a first section and a second section. The first section is used to assemble a 20-foot container 110. The second section is used to assemble a 40-foot container 110.

[0054] Both the first and second sections are equipped with a first electromagnet 130 and a second electromagnet 140. A common longitudinal guide is located at the junction of the first and second sections. The common longitudinal guide has two opposing guide surfaces, both of which are inclined downwards. When the common guide is in the first position, one guide surface extends along the length of the container 110 and is approximately flush with the guide surface of the transverse guide 150. When the common guide is in the second position, one guide surface is inclined towards one end of the container 110, and the other guide surface is inclined towards the other end of the container 110. Thus, when the common longitudinal guide swings to the second position, one guide surface can guide the movement of the top plate installed in the first section in the longitudinal direction, and the other guide surface can guide the movement of the top plate installed in the second section in the longitudinal direction. The arrangement and connection method of the other parts of the common longitudinal guide are roughly the same as those of the longitudinal guide 160, and will not be described again here.

[0055] In this embodiment, the assembly device includes two longitudinal beam assemblies. One longitudinal beam assembly is located on one side of the container 110. The other longitudinal beam assembly is located on the other side of the container 110. The two longitudinal beam assemblies act on the container 110 from both sides to simultaneously straighten the two top side beams of the container 110.

[0056] The longitudinal beam assembly also includes a locking device 190. The locking device 190 can be a locking screw. The locking screw is threaded into the threaded hole of the guide sleeve. The height guide has locking holes corresponding to the locking screws. There are multiple locking holes. The positions of the multiple locking holes correspond one-to-one with the height dimensions of various containers (e.g., 20-foot and 40-foot containers). After the locking screw passes through the threaded hole of the guide sleeve and extends into a specific locking hole, the first frame is locked in the position corresponding to that locking hole. By disengaging the locking screw from the locking hole, the first frame can move in the height direction of the container 110 to be assembled.

[0057] The assembly unit also includes a container conveyor chain and a container positioning device. The container conveyor chain moves the container 110 to be assembled to the assembly station. The container positioning device is used to position the container 110 at the assembly station.

[0058] The container positioning device includes a side reference positioning block located on the first side of the container 110 to be assembled, an end face reference positioning block located at the first end of the container 110 to be assembled, a lateral push cylinder located on the second side of the container 110 to be assembled, and a longitudinal push cylinder located at the second end of the container 110 to be assembled. The cylinder rod of the lateral push cylinder can move in the lateral direction of the container 110 to be assembled. The cylinder rod of the longitudinal push cylinder can move in the longitudinal direction of the container 110 to be assembled.

[0059] In this embodiment, the first longitudinal beam 120 located on the first side of the container 110 to be assembled has a positioning position. When the first longitudinal beam 120 is in the positioning position, the positioning plane of the first longitudinal beam 120 is flush with the reference plane of the side reference positioning block.

[0060] In this embodiment, the processing flow of container 110 is as follows:

[0061] The container conveyor belt moves container 110, which is to be assembled, to this workstation;

[0062] The lateral push cylinder is activated to push the side of the bottom corner piece of one side of the container 110 to be assembled in the width direction of the container 110 to be assembled, so that the side of the bottom corner piece of the other side of the container 110 to be assembled abuts against the reference plane of the side reference positioning block.

[0063] The longitudinal push cylinder is activated to push the end face of the bottom corner piece of one end of the container 110 to be assembled in the length direction of the container 110 to be assembled, so that the end face of the bottom corner piece of the other end of the container 110 to be assembled abuts against the reference plane of the end face reference positioning block.

[0064] The first frame moves vertically until the positioning plane of the first longitudinal beam 120 moves to the height of the top corner piece of the container 110;

[0065] The first longitudinal beam 120 located on the first side of the container 110 to be assembled moves to the positioning position along the width direction of the container 110 to be assembled. At this time, the positioning plane of the first longitudinal beam 120 abuts against the outer side of the top corner piece of the container 110 to be assembled.

[0066] The first longitudinal beam 120 located on the second side of the container 110 to be assembled moves along the width direction of the container 110 to be assembled, so that the positioning plane of the second longitudinal beam 170 abuts against the outer side of the top corner piece of the container 110 to be assembled.

[0067] The second electromagnet 140 moves toward the top side beam of the container 110 to be assembled in order to attract the top side beam.

[0068] The second electromagnet 140 that attracts the top side beam moves toward its straightened position to straighten the top side beam;

[0069] The longitudinal guide 160 swings to the second position;

[0070] The hoisting device lifts the top plate to directly above the container 110 and moves it vertically downwards so that the top plate moves along the guide surfaces of the longitudinal guide 160 and the transverse guide 150 to the top side beam of the container 110.

[0071] The second longitudinal beam 170 swings to the second position so that the pressure foot 180 presses against the upper surface of the top plate;

[0072] Spot weld at the preset positions;

[0073] The second longitudinal beam 170 swings to the first position, the longitudinal guide 160 swings to the first position, and the first electromagnet 130 and the second electromagnet 140 release the top side beam.

[0074] The first longitudinal beam 120 leaves the top corner piece, completing the assembly of the top plate of the current container 110.
