Abstract
Description
Technical Field
[0001] This utility model relates to the field of container packing, specifically to a container packing device. Background Technology
[0002] Currently, it is quite difficult to load large-sized equipment or materials into containers in one go. The more common method is to use cranes and chain hoists, along with manual labor, to load the containers in batches. This is time-consuming, labor-intensive, and very inefficient.
[0003] Chinese patent CN201020250230.0 discloses an automatic loading machine for aluminum alloy profile containers, including a motor, a reducer, a chain transmission system composed of double-row chain gears, double-row chains, single-row chain gears, and single-row chains, and a steel structure platform. The platform has chain running slots on its surface and corresponding chain running grooves welded to its underside. A pushing beam is installed on the platform, with a connecting plate welded to it and connected to the single-row chains. A pushing beam wheel is installed at the lower end of the pushing beam, and a flatbed cart with rollers at the bottom is located on the platform. The automated container loading machine for aluminum alloy profiles enables efficient loading of large-sized aluminum alloy profiles. This machine uses a relatively long single-row chain to drive the pushing beam. However, the long chain is prone to slack. Since the machine lacks a chain tensioning mechanism, slack chains can lead to poor engagement with the sprockets, resulting in skipped teeth or the chain completely disengaging from the sprockets, thus affecting performance. Utility Model Content
[0004] The purpose of this invention is to provide a container loading device that includes a tensioning mechanism to tension the chain and prevent the chain from becoming slack.
[0005] To achieve the above objectives, this utility model provides a container loading device, including a device body, a chain, a balance push arm fixedly connected to the chain, a chain transmission mechanism, and a tensioning mechanism. The tensioning mechanism is fixedly connected to the device body for tensioning the chain. The balance push arm is slidably connected to the device body. The chain transmission mechanism drives the chain to rotate and causes the balance push arm to slide along the length direction of the device body.
[0006] The chain drive mechanism can drive the balance push arm to slide back and forth along the length of the equipment body by rotating in both directions.
[0007] Preferably, the tensioning mechanism includes an adjusting screw, a connecting arm, and a tensioning wheel. The tensioning wheel and the adjusting screw are respectively connected to both ends of the connecting arm. The middle of the connecting arm is rotatably connected to the equipment body. The adjusting screw is connected to the equipment body through an adjusting nut. An adjusting spring is provided between the adjusting screw and the equipment body.
[0008] Preferably, the equipment body includes a tensioning connecting plate, the tensioning connecting plate is provided with a through hole that cooperates with the adjusting screw, the side of the tensioning connecting plate that is fixed to the equipment body is provided with a connection hole, and the equipment body is provided with a mounting hole that cooperates with the connection hole.
[0009] Preferably, auxiliary sprockets are provided in front of and behind the tensioning mechanism along the direction of chain movement. The auxiliary sprockets are fixedly installed, and the chain engages with the auxiliary sprockets above the auxiliary sprockets and with the tensioning wheel below the tensioning wheel.
[0010] Preferably, the device body includes a support frame and a first track located above the support frame, and the balance push arm slides along the first track.
[0011] Preferably, the balance push arm is provided with traveling wheels on both sides, and the equipment body also includes a second track that cooperates with the traveling wheels.
[0012] Preferably, the container loading equipment also includes a transfer rack for carrying goods, the transfer rack being slidably engaged with the first track.
[0013] According to the above technical solution, the balance push arm of this utility model is fixedly connected to the chain. When the chain drive mechanism is activated, the chain moves, and the chain movement can drive the balance push arm to slide along the equipment body. When goods are placed on the equipment body, the balance push arm can push the goods forward, allowing the goods to enter the container.
[0014] After the goods enter the container, the reverse chain drives the balance push arm back to its initial position. Next, the next batch of goods is placed on top of the equipment body, with the goods positioned in front of the balance push arm. The chain operation drives the balance push arm to propel the goods forward. Preferably, the container is placed in front of the equipment body, close to it, and the bottom of the container is at the same height as the bottom surface of the moving goods. When the goods move forward, they will directly enter the container.
[0015] Because the goods to be packed are very long, the stroke of the balance push arm is also very large, resulting in a very long chain. Longer chains are prone to slack during operation. By setting up a tensioning mechanism, reliable tensioning of the chain can be achieved, preventing chain slack from affecting the normal use of the container packing equipment.

[0037] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0038] In this utility model, unless otherwise stated, directional words such as "reciprocating," "both ends," "middle," "front," "rear," "above," "below," and "both sides" contained in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the terminology.
[0039] See Figure 1 The container loading equipment includes a machine body 1, a chain 5, a balance push arm 2 fixedly connected to the chain 5, a chain transmission mechanism 3, and a tensioning mechanism 4. The tensioning mechanism 4 is fixedly connected to the machine body 1 to tension the chain 5. The balance push arm 2 is slidably connected to the machine body 1. The chain transmission mechanism 3 drives the chain 5 to rotate and causes the balance push arm 2 to slide along the length direction of the machine body 1.
[0040] The chain drive mechanism 3 can drive the balance push arm 2 to slide back and forth along the length of the equipment body 1 by rotating in both directions.
[0041] Through the implementation of the above technical solution, the balance push arm 2 is fixedly connected to the chain 5. When the chain drive mechanism 3 is activated, the chain 5 moves, and the movement of the chain 5 can drive the balance push arm 2 to slide along the equipment body 1. When goods are placed on the equipment body 1, the balance push arm 2 can push the goods forward, allowing the goods to enter the container.
[0042] After the goods enter the container, the reverse chain 5 drives the balance push arm 2 back to its initial position. Next, the next batch of goods is placed on top of the equipment body 1, and the goods are located in front of the balance push arm 2. The operation of the chain 5 can drive the balance push arm 2 to push the goods forward. Preferably, the container is placed in front of the equipment body 1, close to the equipment body 1, and the bottom of the container is adapted to the height of the bottom surface of the goods. When the goods move forward, they will directly enter the container.
[0043] Because the goods to be packed are very long, the stroke of the balance push arm 2 is also very large, and therefore the chain 5 is also very long. The long chain 5 is prone to slack during operation. By setting the tensioning mechanism 4, the chain 5 can be reliably tensioned, so as to avoid the chain 5 slack affecting the normal use of the container packing equipment during use.
[0044] In one embodiment, two chains 5 are provided, and the two chains 5 are fixedly connected to both sides of the balance push arm 2 respectively. The two chain drive mechanisms 3 operate synchronously, making the balance push arm 2 run more smoothly.
[0045] In this embodiment, preferably, the tensioning mechanism 4 includes an adjusting screw 41, a connecting arm 42, and a tensioning wheel 43. The tensioning wheel 43 and the adjusting screw 41 are respectively connected to both ends of the connecting arm 42. The middle of the connecting arm 42 is rotatably connected to the equipment body 1. The adjusting screw 41 is connected to the equipment body 1 through an adjusting nut 44. An adjusting spring 45 is provided between the adjusting screw 41 and the equipment body 1. The adjusting spring 45 is used to keep the position of the connecting arm 42 stable.
[0046] By adjusting the mating position of the adjusting nut 44 and the adjusting screw 41, the connecting arm 42 can be driven to rotate. When the connecting arm 42 rotates, the tensioning wheel 43 located at the other end of the connecting arm 42 will also rotate accordingly. By adjusting the adjusting nut 44 to make the tensioning wheel 43 rotate in the direction of tensioning the chain 5, the tensioning mechanism 4 can achieve the tensioning effect on the chain 5.
[0047] In one embodiment, by rotating the adjusting nut 44 downwards, the adjusting screw 41 moves upwards under the action of the adjusting spring 45, causing the tensioning wheel 43 at the other end of the connecting arm 42 to move downwards. The tensioning wheel 43 presses the chain 5 downwards, thus achieving the tensioning effect on the chain 5. During equipment use, this method of tensioning the chain 5 by rotating the adjusting nut 44 is very beneficial for on-site work and can improve the efficiency of tensioning the chain 5.
[0048] The adjusting spring 45 is set to a pre-compressed state. The pre-compressed adjusting spring 45 will apply an upward thrust to the connecting arm 42. This thrust is used to maintain the tension of the chain 5 so that the chain 5 will not be slack or too tight.
[0049] In this embodiment, preferably, the device body 1 includes a tensioning connecting plate 21, the tensioning connecting plate 21 is provided with a through hole that cooperates with the adjusting screw 41, the side of the tensioning connecting plate 21 that is fixed to the device body 1 is provided with a connecting hole, and the device body 1 is provided with a mounting hole that cooperates with the connecting hole.
[0050] The main body 1 includes a tensioning connecting plate 21, which has a through hole that cooperates with the adjusting screw 41. An adjusting spring 45 is located between the tensioning connecting plate 21 and the adjusting screw 41. The adjusting spring 45 and the adjusting screw 41 are coaxially arranged. A nut is located on the other side of the tensioning connecting plate and cooperates with the adjusting screw 41.
[0051] In one embodiment, the tensioning connecting plate 21 is fixed to the device body 1 and has a plurality of connecting holes along the height direction. The device body 1 is provided with mounting holes that cooperate with the connecting holes. By using different connecting holes and mounting holes to cooperate, the initial position of the tensioning wheel 43 can be changed.
[0052] When the container loading equipment is not in use, the overall height of the tensioning mechanism 4 can be adjusted by replacing the connecting hole that matches the mounting hole. At this time, the position of the connecting arm 42 and the equipment body 1 also needs to be adjusted accordingly.
[0053] In another embodiment, the device body 1 is provided with multiple mounting holes along the height direction, and the tensioning connecting plate 21 can also achieve the purpose of adjusting the overall height of the tensioning mechanism 4 by cooperating with the mounting holes of different heights.
[0054] Preferably, the tensioning connecting plate 21 is provided with multiple connecting holes along the height direction, and the equipment body 1 is provided with multiple mounting holes along the height direction. In this way, by cooperating with the connecting holes of different heights and the mounting holes of different heights, a wider range of adjustment of the overall height of the tensioning mechanism 4 can be achieved.
[0055] Preferably, the height of the connection position between the connecting arm 42 and the equipment body 1 is also adjustable. By synchronously adjusting the tensioning connecting plate 21 and the connection height between the connecting arm 42 and the equipment body 1, the tensioning effect on the chain 5 can be reliably achieved.
[0056] Adjusting the height of the tension wheel in this way is more inconvenient than using the adjusting screw 41, as it requires disassembling part of the equipment structure. Therefore, it can be done during the equipment's idle time.
[0057] In this embodiment, preferably, auxiliary sprockets 46 are provided in front of and behind the tensioning mechanism 4 along the direction of movement of the chain 5. The chain 5 cooperates with the auxiliary sprocket 46 above the auxiliary sprocket 46 and with the tensioning wheel 43 below the tensioning wheel 43.
[0058] The auxiliary sprockets 46 at both ends support the chain 5 and guide it to run along a predetermined path, preventing the chain 5 from deviating or getting stuck, and ensuring that the chain 5 can run stably and efficiently.
[0059] In this preferred embodiment, the device body 1 includes a support frame 11 and a first track 12 located above the support frame 11, with the balance push arm 2 sliding along the first track 12.
[0060] The first track 12 is mainly used to carry goods. When the chain drive mechanism 3 rotates forward, the chain 5 drives the balance push arm 2 to move forward along the first track 12. By setting the first track 12, the equipment body 1 can be set as a frame structure. The first track 12 supports the goods and provides a track for movement, which can effectively reduce the complexity of the structure of the equipment body 1.
[0061] In one embodiment, preferably, the balance push arm 2 is fixedly connected to the chain 5 via a connecting plate 21. Limit sensors are respectively installed at both ends of the device body 1. The limit sensors are electrically connected to the chain drive mechanism 3. When the balance push arm 2 moves forward to the front limit sensor, the front limit sensor will control the chain drive mechanism 3 to stop. Similarly, when the balance push arm 2 moves backward to the rear limit sensor, the rear limit sensor will control the chain drive mechanism 3 to stop. This ensures that the balance push arm 2 can only move horizontally along the first track 12 above the device body 1 and will not flip with the chain 5.
[0062] In order to prevent the chain drive mechanism 3 from failing to stop in time in case of limit sensor failure or other unexpected situations, limiters 14 are respectively installed at both ends of the equipment body 1 to mechanically limit the balance push arm 2.
[0063] In this embodiment, preferably, the balance push arm 2 is provided with walking wheels 22 on both sides, and the equipment body 1 also includes a second track 13 that cooperates with the walking wheels 22.
[0064] The traveling wheels 22 on both sides of the balance push arm 2 are respectively engaged with the second track 13 to guide the balance push arm 2, so that the balance push arm 2 can reliably move along the first track 12.
[0065] In one embodiment, the second track 13 is configured as a U-shape, and the walking wheel 22 enters the second track 13 through the opening of the U-shape. The bottom of the second track 13 on both sides can limit the walking wheel 22.
[0066] The opening of the second track 13 facing the cargo can also limit the position of the transfer rack 7 loaded with cargo, thereby ensuring the reliability of the position of the transfer rack 7 during long-distance transportation.
[0067] In this embodiment, preferably, the container loading equipment further includes a transfer rack 7 for carrying goods, the transfer rack 7 being slidably engaged with the first track 12.
[0068] The transfer rack 7 is slidably engaged with the first track 12. When the balance push arm 2 moves, it will push the transfer rack 7 and the goods located on the transfer rack 7 to move forward together.
[0069] The transfer rack 7 has upwardly inclined guide surfaces at both ends, and the front end of the balance push arm 2 has an inclined surface that cooperates with the guide surfaces. One end of the transfer rack 7's guide surface cooperates with the balance push arm 2, and the balance push arm 2 pushes it. The other end of the transfer rack 7's guide surface can cooperate with the bottom surface of the container, allowing the transfer rack 7 to adapt to the height position of the container over a wider range, and enabling the transfer rack 7 to reliably enter the container.
[0070] The height of the limiter 14 near one end of the container is not higher than the crossbeam of the transfer rack 7 to avoid interference with the crossbeam of the transfer rack 7. After the transportation is completed, the transfer rack 7 will remain in the container and will not be removed.
[0071] In this embodiment, preferably, the container loading equipment further includes a container support 6, which is connected to the equipment body 1, and the height of the container support 6 is lower than the height of the equipment body 1.
[0072] After the container is placed on the container support 6, the height of the bottom of the container is adapted to the height of the first track 12, so that the goods transported by the first track 12 can reliably enter the container and achieve smooth loading.
[0073] In this embodiment, preferably, a locator 61 is provided on the side of the container support 6 facing the container, and the locator 61 cooperates with the positioning hole of the container to position the container.
[0074] The locator 61, in conjunction with the positioning hole, enables reliable positioning of the container, thereby ensuring the smooth progress of the packaging and transfer process.
[0075] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
[0076] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
[0077] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
