Description

Technical Field

[0001] The present invention relates to the technical field of full-automatic twist locks for containers, and more specifically to a device and method for detecting a gap between a full-automatic twist lock for a container and a container corner. Background Art

[0002] In container transportation, the use of fully automatic twist locks has greatly improved the efficiency and safety of cargo loading and unloading. However, in order to ensure that the twist locks can correctly and safely fix the container, the gap between the twist locks and the container corners must be detected.

[0003] After the production of the container's fully automatic twist lock is completed, it must undergo strict quality inspection to ensure that it meets the use standards. During the inspection process, the fully automatic twist lock produced is usually installed in a lock foot prop to simulate the connection scenario of the container in actual use, and measure the distance between the upper and lower lock feet. By accurately measuring this distance, check whether the closure and locking function of the twist lock meet the specified standards to ensure that the distance between the upper and lower lock feet is within the specified range. Through this test, it can be effectively determined whether the twist lock can withstand external pressure and maintain stable locking during transportation, while avoiding problems such as loose locking or loosening due to unqualified spacing. Ensure the safety and reliability of container transportation.

[0004] The detection scenario usually requires manual installation of the fully automatic twist lock on the base. Manual repetitive labor not only increases the workload, but also increases the detection error, resulting in inaccurate detection results.

[0019] A method for detecting the gap between a container's fully automatic twist lock and a container corner comprises the following steps:

[0020] S1: The conveyor belt drives the carrier mechanism to move through the moving mechanism. The inspector slides the lock head of the workpiece mechanism into the installation slot of each passing station, and the interception head blocks the installation slot to prevent the workpiece mechanism from falling off;

[0021] S2: After each top seat stops under the electric telescopic rod, the electric telescopic rod pushes the top seat down so that the lock tongue is inserted into the slot;

[0022] S3: When the thickness of the partition is small, the ruler will be inserted into the top seat, pushing the first rack to slide, causing the interception head to retract into the top seat, and then the top seat rises, bringing out the workpiece mechanism, and moves horizontally to the top of the first box. In this process, the push bar causes the top seat to tilt, and the unqualified workpiece mechanism is poured into the first box;

[0023] S4: The electric telescopic rod presses down the top seat to insert the workpiece mechanism into the slot. If the distance between the lock head and the bottom of the installation slot is too large, the downward pressure will cause the lock head to rise and push the top rod upward, eventually causing the interception head to be retracted into the top seat. When the top seat then reaches the top of the first box, the unqualified workpiece mechanism is poured into the box;

[0024] S5: If the tests in S3 and S4 are qualified, the intercepting head does not move, and the internal workpiece mechanism of the corresponding top seat will not fall when it passes the first box. When it reaches the second box, the push block pushes the slider to retract the intercepting head into the top seat, and the corresponding workpiece mechanism slides into the second box.

[0025] Compared with the prior art, the advantages of the present invention are:

[0026] 1. By setting a side-opening installation slot on the top seat, it is convenient for the inspector to push the lock head into the top seat, and complete the installation of the workpiece mechanism easily and quickly. In addition, the entire inspection process is transported by the conveyor belt, which can not only complete the installation and gap inspection of the workpiece mechanism, but also use the push bar to push the top seat to tilt the top seat and dump the workpiece mechanism by category, so as to pick out unqualified products and recycle qualified products. The assembly line method can greatly improve the inspection efficiency and sorting efficiency.

[0027] 2. When the lock tongue is inserted into the slot, the column on the top of the base is pushed by the pressure block in the installation slot, thereby pushing out the positioning rod and squeezing the lock head, so that the workpiece mechanism moves to a specific position, quickly and accurately helping the workpiece mechanism to position, preventing the lock head from sliding freely in the installation slot, and also allowing the lock tongue to be accurately inserted into the slot to achieve matching.

[0028] 3. An intercepting head is provided in the installation groove, and the top seat is close to the base. During the gap detection of the workpiece mechanism, the height of the scale and the height change of the lock head inside the installation groove can be used to judge whether the thickness of the partition is qualified, whether the distance between the lock head and the partition is qualified, and other quality problems. If there is a problem with any of these, the intercepting head will be retracted into the top seat, and the push strip will be used to push the top seat to tilt, so that qualified products can be easily distinguished from unqualified products and classified for processing.

DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] For example, see Figures 1 to 14 As shown, the present invention discloses a fully automatic twist lock and box corner gap detection device for a container, comprising a conveying mechanism 1, the conveying mechanism 1 comprises a conveying frame 13, and a conveyor belt 14 is installed inside the conveying frame 13;

[0047] A moving mechanism 2 is installed on the conveyor belt 14. The moving mechanism 2 includes a plurality of pillars 21 equidistantly installed on the surface of the conveyor belt 14. A support plate 22 is installed at the outer end of the pillar 21. A lifting plate 26 is slidably connected to the surface of the support plate 22. A rotating sleeve 27 is installed at the bottom of the lifting plate 26.

[0048] The rotating sleeve 27 is provided with a carrier mechanism 4, which includes a rotating shaft 41 and a torsion spring 42 installed inside the rotating sleeve 27. The rotating shaft 41 is elastically connected to the inside of the rotating sleeve 27 through the torsion spring 42. Both ends of the rotating shaft 41 are connected to a top seat 43. The top seat 43 is provided with a mounting groove 44 that runs through the side and bottom surfaces thereof.

[0049] A workpiece mechanism 5 is installed in the installation groove 44. The workpiece mechanism 5 includes a lock head 51 installed in the installation groove 44. A partition plate 52 is fixed to the bottom of the lock head 51. A lock tongue 53 is fixed to the bottom of the partition plate 52.

[0050] An interception mechanism 6 is disposed inside the top seat 43 . The interception mechanism 6 includes a fifth spring 61 and an interception head 62 installed inside the top seat 43 . The interception head 62 is elastically connected to the inside of the top seat 43 via the fifth spring 61 .

[0051] Attached Figure 1 The figure shows a part of the fully automatic twist lock and box corner gap detection experimental simulation device. The positions of the five top seats 43 from left to right on the conveyor belt 14 are respectively No. 1, No. 2, No. 3, No. 4 and No. 5.

[0052] In the initial state, the lifting plate 26 is raised to the highest position, the slide bar 25 is at the top of the guide groove 23 , and the limiting block 47 is inserted into the limiting hole 28 to limit the rotation of the top seat 43 .

[0053] The motor drives the conveyor belt 14 inside the conveyor frame 13 to rotate cyclically, and the conveyor belt 14 drives each moving mechanism 2 on its surface to move cyclically (the conveyor belt 14 will stop for a certain period of time after each movement, and the distance of each movement is equal to the vertical distance between the central axes of two adjacent pillars 21), thereby driving a number of carrier mechanisms 4 to move. When the carrier mechanism 4 reaches the No. 1 position, the inspection personnel install the workpiece mechanism 5 into the top seat 43. The specific operation is as follows: align the lock head 51 with the installation groove 44 opened on the side of the top seat 43, and push it into the installation groove 44 to make the lock head 51 slide to the installation position. Deep in the installation groove 44, the side surfaces of the intercepting heads 62 on both sides of the installation groove 44 are inclined surfaces. When the lock head 51 slides into the installation groove 44, the intercepting heads 62 are pushed into the top seat 43 by the extrusion force, so that the intercepting heads 62 compress the fifth spring 61. After the lock head 51 is installed in place, the bottom surfaces of both sides of the lock head 51 contact the bottom surface of the installation groove 44, and the two ends of the lock head 51 no longer contact the intercepting heads 62. Under the elastic force of the fifth spring 61, the intercepting heads 62 bounce from the top seat 43 into the installation groove 44, blocking the lock head 51 and preventing the workpiece mechanism 5 from falling off during the movement. In this process, the inspection personnel only need to install the lock head 51 into the installation groove 44 at will, and let the intercepting heads 62 bounce from the top seat 43 into the installation groove 44 to block the lock head 51. It does not require too many actions, and the operation is simple and fast, which simplifies the manual workload and helps to improve the inspection efficiency of the workpiece mechanism 5.

[0054] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 14The conveying mechanism 1 also includes a bottom plate 11 installed at the bottom of the conveying frame 13, two boxes 12 are installed on the bottom plate 11, an electric telescopic rod 15 is installed on the top of the conveying frame 13, a pressure strip 16 is installed on the side of the conveying frame 13, a push strip 17 is installed on the top of the pressure strip 16, and two push blocks 18 are fixed to the top surface of the end of the push strip 17 at intervals.

[0055] The moving mechanism 2 also includes two guide grooves 23 symmetrically arranged on the side of the support plate 22, a first spring 24 is installed inside the top of the guide groove 23, a slide rod 25 is slidably connected in the guide groove 23, and the slide rod 25 is elastically connected in the guide groove 23 through the first spring 24. The two slide rods 25 are fixed to the back side of the lifting plate 26, and a limiting hole 28 is penetrated on the lifting plate 26.

[0056] A matching mechanism 3 is provided on the top surface of the bottom plate 11, and the matching mechanism 3 includes a base 31 installed on the top surface of the bottom plate 11. A slot 32 is provided on the top surface of the base 31. Two scales 33 and a stand 34 are installed on the top surface of the base 31. The two scales 33 are symmetrically arranged. A second spring 35 and a column 36 are installed on the top of the stand 34. The column 36 is slidably connected to the top surface of the stand 34 through the second spring 35, and a positioning rod 37 is fixed to the side of the column 36.

[0057] The carrier mechanism 4 also includes a pressure block 45 fixed to the top of the mounting groove 44, and a third spring 46 and a limiting block 47 are installed inside the top seat 43. The limiting block 47 is elastically connected to the side of the top seat 43 through the third spring 46, and the limiting block 47 is slidably connected to the corresponding limiting hole 28. Two unlocking rods 48 and a fourth spring 49 are symmetrically arranged in the top seat 43. The unlocking rod 48 is elastically connected to the inside of the top seat 43 through the fourth spring 49, and a slider 491 is installed on the top of the unlocking rod 48.

[0058] The intercepting mechanism 6 also includes a triangular block 63 fixed to the top of the intercepting head 62, the unlocking rod 48 abuts against the side of the corresponding intercepting head 62, and the inside of the top seat 43 is equipped with a plug plate 64 and a tooth plate 65, the plug plate 64 abuts against the intercepting head 62, the plug plate 64 is fixedly connected to the tooth plate 65, and a large gear 66, a small gear 67 and a ratchet gear 68 are rotatably connected inside the top seat 43, the large gear 66, the small gear 67 and the ratchet gear 68 are coaxially connected in sequence, and the large gear 66 is meshingly connected to the tooth plate 65.

[0059] After the carrier mechanism 4 on the first position moves to the second position, the carrier mechanism 4 is aligned with the matching mechanism 3, and then the electric telescopic rod 15 is started, and its output end pushes the top seat 43 downward. Due to the connection between the limiting block 47 and the limiting hole 28, the top seat 43 makes the lifting plate 26 slide downward with the top seat 43, and the lifting plate 26 drives the slide bar 25 to slide in the guide groove 23, and the slide bar 25 stretches the first spring 24 inside the guide groove 23. Figure 3As shown in FIG. 4 , the bottom end of the guide groove 23 has a symmetrical corner. The top seat 43 drives the workpiece mechanism 5 installed inside it to gradually insert the lock tongue 53 into the slot 32 on the base 31. During the process of the lock tongue 53 inserting into the slot 32, when the slide bar 25 slides to the corner at the bottom of the guide groove 23, the convex part of the side of the lock tongue 53 just hits the edge of the slot 32. Figure 7 As shown, as the slide bar 25 continues to slide at the corner of the guide slot 23, the carrier mechanism 4 slides synchronously, thereby driving the workpiece mechanism 5 to move leftward and downward, so that the lock tongue 53 can be smoothly inserted into the slot 32. After insertion, the slide bar 25 reaches the straight groove at the bottom of the guide slot 23, the lifting plate 26, the carrier mechanism 4 and the workpiece mechanism 5 return to the original position, the protruding part of the lock tongue 53 is engaged with the top of the slot 32, and the top seat 43 is locked with the base 31, thereby simulating the state of the fully automatic twist lock limiting the locking angle of the container.

[0060] When the lock tongue 53 is inserted into the slot 32, the column 36 in the stand 34 at the top of the base 31 will conflict with the pressure block 45 in the installation slot 44. The pressure block 45 squeezes the column 36, causing the column 36 to lengthen the second spring 35 and push the positioning rod 37 out of the stand 34. The positioning rod 37 conflicts with the side of the lock head 51. As the positioning rod 37 slides out, the lock head 51 gradually moves to a specific position in the installation slot 44, playing a positioning role, preventing the lock head 51 from sliding freely in the installation slot 44. In this way, the inspection personnel only need to simply install the workpiece mechanism 5 into the installation slot 44, and automatically complete the positioning of the workpiece mechanism 5 during the process of inserting the lock tongue 53 into the slot 32, thereby simplifying the manual workload and improving the inspection efficiency. At the same time, it also allows the lock tongue 53 to be accurately inserted into the slot 32 to achieve matching.

[0061] Example 3: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 14 A classification mechanism 7 is installed inside the top seat 43, and the classification mechanism 7 includes two first racks 71 and second racks 73 symmetrically slidably connected to the inside of the top seat 43. The first rack 71 and the second rack 73 are both meshed and connected with the corresponding pinion 67. The first rack 71 and the second rack 73 are both installed with a sixth spring 72. There are two levers 74 symmetrically rotating inside the top seat 43, and two push rods 75 and a seventh spring 76 are symmetrically installed in the mounting groove 44. The push rod 75 is elastically connected to the inside of the mounting groove 44 through the corresponding seventh spring 76, and the top ends of the second rack 73 and the push rod 75 respectively resist the bottom surfaces of the two ends of the corresponding lever 74.

[0062] An anti-reversal mechanism 8 is installed inside the top seat 43, and the anti-reversal mechanism 8 includes two telescopic blocks 81 and an eighth spring 82 symmetrically installed inside the top seat 43. The telescopic block 81 is elastically connected to the inside of the top seat 43 through the corresponding eighth spring 82. The side wall of the telescopic block 81 is connected to one end of a connecting rod 83. Two sliding boxes 84 are symmetrically installed inside the top seat 43. A slide plate 85 is slidably connected inside the sliding box 84, and the other end of the connecting rod 83 passes through the sliding box 84 and is installed on one side of the slide plate 85. The other side of the slide plate 85 is rotatably connected to a locking tooth 86.

[0063] Due to errors and other reasons during the processing of the workpiece mechanism 5, the thickness of the partition 52 may be different, so that after the workpiece mechanism 5 is connected to the slot 32, the distance between the base 31 and the top seat 43 exceeds the specification; if the distance between the lock head 51 and the partition 52 is too large, the lock head 51 will be too loose when installed in the installation groove 44, and it is easy to move, which is not conducive to the overall stability. Therefore, a ruler 33 is set on the top surface of the base 31 to measure the distance between the base 31 and the top seat 43 after the lock tongue 53 is inserted into the slot 32. When the thickness of the partition 52 is too small, the workpiece mechanism 5 is considered unqualified, and the ruler 33 will be inserted into the top seat 43, thereby pushing the first rack 71 at the bottom of the top seat 43 upward. The first rack 71 compresses the sixth spring 72 while driving the small gear 67 to rotate. The small gear 67 drives the large gear 66 to rotate, thereby expanding the displacement distance of the tooth plate 65, and then drives the plug plate 64 to move a greater distance. The plug plate 64 pulls the intercepting head 62 back to the top seat 43, and the intercepting head 62 compresses the fifth spring 61, and the intercepting head 62 releases the restriction on the lock head 51. When the electric telescopic rod 15 drives the top seat 43 to press the workpiece mechanism lock tongue 53 into the slot 32, the partition 52 contacts the top of the base 31. If the distance between the lock head 51 and the partition 52 is too large, the pressure will cause the lock head 51 to rise, thereby pushing the top rod 75 inside the installation slot 44 to rise. While the top rod 75 compresses the seventh spring 76, it causes the lever 74 to swing. The other end of the lever 74 pushes the second rack 73 downward. While the second rack 73 compresses the sixth spring 72, it drives the pinion 67 to rotate, which can also eventually retract the intercepting head 62 into the top seat 43.

[0064] After the detection is completed, the electric telescopic rod 15 is reset, and the slide bar 25 drives the lifting plate 26 to rise under the elastic force of the first spring 24, and the lifting plate 26 drives the carrier mechanism 4 to rise, and the carrier mechanism 4 drives the workpiece mechanism 5 to rise, and the lock tongue 53 is pulled out from the slot 32, and then the conveyor belt 14 continues to move, driving the carrier mechanism 4 on the second position to move to the third position. In this process, since the length of the pressure strip 16 is greater than the push strip 17, the pressure strip 16 first hits the limit block 47 inserted into the limit hole 28, so that the limit block 47 slides into the inside of the top seat 43 and disengages from the limit hole 28, and then the push strip 17 starts to hit the side wall of the top seat 43, thereby squeezing the top seat 43, so that the top seat 43 drives the rotating shaft 41 to rotate in the rotating sleeve 27, and the torsion spring 42 accumulates force. When the top seat 43 reaches the third position, it just completes the tilting, and the workpiece mechanism 5 installed in the installation slot 44 slides out and falls into the box 12 below the third position (here the box 12 is used to recycle defective products). If the workpiece mechanism 5 detected at the second position is qualified, the ruler 33 will not be inserted into the top seat 43, the lock head 51 will not drive the top rod 75 to rise, and finally the intercepting head 62 will not move. Therefore, when passing the third position, even if the top seat 43 is tilted, the workpiece mechanism 5 will not slide out of the mounting groove 44 due to the obstruction of the intercepting head 62. The conveyor belt 14 continues to drive the carrier mechanism 4 on the third position to move. In the process of reaching the fourth position, the top seat 43 always remains in an inclined state. At the same time, the push block 18 set at the end of the push strip 17 begins to resist and push the slider 491 on the top of the top seat 43, so that the slider 491 drives the unlocking rod 48 to slide, thereby squeezing the triangular block 63 on the top of the intercepting head 62, causing the intercepting head 62 to slide into the top seat 43, releasing the workpiece mechanism 5, and the qualified workpiece mechanism 5 slides into the box 12 under the fourth position (here the box 12 is used to recycle qualified products). The conveyor belt 14 continues to drive the carrier mechanism 4 to move, and the slider 491 passes over the push block 18. The unlocking rod 48 is reset under the elastic force of the fourth spring 49, driving the slider 491 to reset, and no longer squeezing the triangular block 63, and the intercepting head 62 rebounds back into the mounting groove 44 under the elastic force of the fifth spring 61. The pressure strip 16 and the push strip 17 no longer contact the lifting plate 26 and the top seat 43. Under the elastic force of the torsion spring 42, the top seat 43 rotates again to contact the side of the lifting plate 26, and the limiting block 47 is reinserted into the limiting hole 28. When it reaches the fifth position, the carrier mechanism 4 is completely reset.

[0065] During the process of installing the lock head 51 into the installation groove 44, the lock head 51 will squeeze the telescopic block 81 inside the installation groove 44. The telescopic block 81 compresses the eighth spring 82 and pushes the connecting rod 83 to slide. The connecting rod 83 drives the slide plate 85 in the slide box 84 to slide in the direction close to the ratchet gear 68, thereby driving the locking tooth 86 elastically connected to the slide plate 85 through the torsion spring 42 to approach the ratchet gear 68, so that the locking tooth 86 cooperates with the teeth of the ratchet gear 68. When the first rack 71 or the second rack 73 drives the pinion 67 to rotate due to the unqualified workpiece mechanism 5, the locking tooth 86 does not affect the rotation of the ratchet gear 68 in the rotation direction, that is, it does not affect the rotation of the pinion gear 67 and the large gear 66, but will prevent the ratchet gear 68 from reversing, thereby avoiding the intercepting head 62 from resetting after the detection is completed. After the lock head 51 slides out of the mounting groove 44, the telescopic block 81 loses the squeezing of the lock head 51 and is reset under the elastic force of the eighth spring 82, thereby driving the slide plate 85 to reset through the connecting rod 83, and the slide plate 85 drives the lock tooth 86 to reset, and the lock tooth 86 loses the restriction on the ratchet gear 68. Therefore, the small gear 67 and the large gear 66 can rotate freely and will not prevent the intercepting head 62 from sliding.

[0066] This embodiment also discloses a method for detecting the gap between a fully automatic twist lock and a container corner, comprising the following steps:

[0067] S1: The conveyor belt 14 drives the carrier mechanism 4 to move through the moving mechanism 2, and the inspector slides the locking head 51 of the workpiece mechanism 5 into the installation groove 44 of each passing station, and the intercepting head 62 blocks the installation groove 44 to prevent the workpiece mechanism 5 from falling off;

[0068] S2: After each top seat 43 stops below the electric telescopic rod 15, the electric telescopic rod 15 pushes the top seat 43 down, so that the locking tongue 53 is inserted into the slot 32;

[0069] S3: When the thickness of the partition 52 is small, the scale 33 will be inserted into the top seat 43, pushing the first rack 71 to slide, thereby causing the interception head 62 to be retracted into the top seat 43, and then the top seat 43 rises, taking out the workpiece mechanism 5, and moving horizontally to the top of the first box 12. In this process, the push bar 17 tilts the top seat 43, and the unqualified workpiece mechanism 5 is poured into the first box 12;

[0070] S4: The electric telescopic rod 15 presses down the top seat 43 to insert the workpiece mechanism 5 into the slot 32. If the distance between the lock head 51 and the bottom of the installation slot 44 is too large, the downward pressure will cause the lock head 51 to rise and push the top rod 75 upward, and finally the intercepting head 62 will be retracted into the top seat 43. When the top seat 43 subsequently reaches the top of the first box 12, the unqualified workpiece mechanism 5 will be poured into the box 12.

[0071] S5: If the detection in S3 and S4 is qualified, the intercepting head 62 does not move, and the corresponding top seat 43 does not fall when passing the first box 12. When reaching the second box 12, the push block 18 pushes the slider 491 to retract the intercepting head 62 into the top seat 43, and the corresponding workpiece mechanism 5 slides into the second box 12.

[0072] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
