Detailed Embodiment

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] A marking device for a luggage shell includes an intermittent conveyor belt 1. The intermittent conveyor belt 1 adopts the prior art, such as an intermittent belt conveyor, or an "intermittent belt conveying device" with the patent number "CN107934401A". An intermittent feeding mechanism, a marking mechanism, and a resisting and limiting mechanism are sequentially arranged on the intermittent conveyor belt 1 along the conveying direction. The intermittent feeding mechanism is arranged above the intermittent conveyor belt through a bracket 2, and a centering positioning mechanism installed on the intermittent conveyor belt 1 is arranged below the intermittent feeding mechanism;

[0023] The intermittent feeding mechanism is used to place the luggage case shell 21 on the intermittent conveyor belt 1 for conveying at a certain frequency. The marking mechanism is used to mark the surface of the luggage case shell 21. The anti-blocking and limiting mechanism is used to block the luggage case shell 21 after it is conveyed to the lower part of the marking mechanism, facilitating marking. After the luggage case shell 21 is placed on the intermittent conveyor belt 1, it is adjusted by the centering mechanism, and the luggage case shell 21 is located at the center of the intermittent conveyor belt 1, facilitating marking;

[0024] The intermittent feeding mechanism includes two first cylinders 3 symmetrically installed on the bracket 2. The telescopic rods of the first cylinders 3 extend inwards and are fixedly connected with a horizontally arranged support plate 4. Above the first cylinders 3, there are second cylinders 5. The number of the second cylinders 5 is two and they are symmetrically installed on the bracket 2. The second cylinders 5 and the first cylinders 3 are both horizontally arranged. The telescopic rods of the second cylinders 5 extend inwards and are fixedly connected with a horizontally arranged separation insert 6. The separation insert 6 is arranged at an interval from the support plate 4.

[0025] Initially, the two first cylinders 3 drive the two support plates 4 to synchronously extend inwards, and the two second cylinders 5 drive the two separation inserts 6 to synchronously retreat outwards, so as to make way for the two support plates 4. A number of stacked luggage case shells 21 are placed on the two support plates 4 in a manner with the opening facing downwards. The remaining edges 22 on both sides of the luggage case shell 21 are respectively supported on the two support plates 4;

[0026] When feeding is required, the two second cylinders 5 drive the two separation inserts 6 to synchronously move inwards and insert into the gap between the remaining edge 22 of the lowermost luggage case shell 21 and the remaining edge 22 of the luggage case shell 21 above it to support all the luggage case shells 21 above. Then, the two first cylinders 3 drive the two support plates 4 to retreat outwards. After the lowermost luggage case shell 21 loses the support of the support plate 4, it drops onto the intermittent conveyor belt 1 by its own gravity. Then, the two support plates 4 move inwards to the lower part of the luggage case shell 21, and the two separation inserts 6 retreat outwards. Thus, the several luggage case shells 21 above will drop onto the two support plates 4 for support;

[0027] After the luggage case shell 21 falls onto the intermittent conveyor belt 1, due to the influence of air buoyancy, the position of the luggage case shell 21 will shift left and right and back and forth after it falls on the intermittent conveyor belt 1. Therefore, the left and right directions of the luggage case shell 21 are adjusted by the centering mechanism so that the luggage case shell 21 is located in the middle position of the intermittent conveyor belt 1. Then, the intermittent conveyor belt 1 starts and conveys the luggage case shell 21 to the lower part of the marking mechanism. The resisting and limiting mechanism is used to resist the luggage case shell 21 in front of the conveying direction of the luggage case shell 21 to make it stay at the accurate marking position. And the moving distance of the intermittent conveyor belt 1 should be greater than the distance for the luggage case shell 21 to be conveyed to the marking position to ensure that the luggage case shell 21 can touch the resisting and limiting mechanism and stop, so as to ensure that the luggage case shell 21 can stay at the accurate marking position, and thus the front and back deviation of the luggage case shell 21 falling on the intermittent conveyor belt 1 can be adjusted.

[0028] While marking, the intermittent feeding mechanism simultaneously places the next luggage case shell 21 on the intermittent conveyor belt 1.

[0029] Through the cooperation of the support plate 4 and the separating insert 6, a number of stacked luggage case shells 21 can be intermittently dropped onto the intermittent conveyor belt 1, which can ensure that the directions of the luggage case shells 21 falling onto the intermittent conveyor belt 1 are consistent, that is, the orientations of the length directions of the luggage case shells 21 tend to be consistent, reducing the mechanisms for adjusting the directions of the luggage case shells 21, which is beneficial to the positioning during subsequent marking.

[0030] In a preferred technical solution, first guide rods are arranged in parallel on both sides of the first cylinder 3, and the bracket 2 is provided with first guide holes adapted to the first guide rods. One end of the first guide rod is fixedly connected to the support plate 4, and the other end of the first guide rod passes through the first guide hole; second guide rods 19 are arranged in parallel on both sides of the second cylinder 5, and the bracket 2 is provided with second guide holes adapted to the second guide rods 19. One end of the second guide rod 19 is fixedly connected to the separating insert 6, and the other end of the second guide rod 19 passes through the second guide hole.

[0031] The first guide rods for auxiliary use are arranged on both sides of the first cylinder 3, and the second guide rods 19 for auxiliary use are arranged on both sides of the second cylinder 5, which are used to improve the stability of the support plate 4 and the separating insert 6 when they are pressed by gravity.

[0032] Preferred technical solution: The centering positioning mechanism includes two clamping rods 8 located above the intermittent conveyor belt 1. The length direction of the clamping rods 8 is parallel to the conveying direction of the intermittent conveyor belt 1. The midpoint of the connection line of the two clamping rods 8 corresponds to the center line of the intermittent conveyor belt 1. On both sides of the intermittent conveyor belt 1, a horizontally arranged third air cylinder 9 is installed respectively. The telescopic direction of the third air cylinder 9 is perpendicular to the conveying direction of the intermittent conveyor belt 1. The telescopic rods of the two third air cylinders 9 extend out and are fixedly connected to the two clamping rods 8 respectively.

[0033] After the upper luggage case shell 21 falls onto the intermittent conveyor belt 1, the two clamping rods 8 on both sides are respectively driven by the two third air cylinders 9 to move synchronously towards the middle, clamp the luggage case shell 21 from both sides, and make the luggage case shell 21 located on the center line of the intermittent conveyor belt 1, so as to adjust the deviation on the left and right sides of the luggage case shell 21 to achieve centering.

[0034] Preferred technical solution: The blocking and limiting mechanism includes a fourth air cylinder 17 installed on one edge of the intermittent conveyor belt 1. The telescopic rod of the fourth air cylinder 17 extends inwards and is fixedly connected with a blocking rod 18.

[0035] When the luggage case shell 21 is conveyed forward, the fourth air cylinder 17 drives the blocking rod 18 to extend towards the middle and block in front of the luggage case shell 21 in the conveying direction, so that the luggage case shell 21 stops advancing and the stopping position corresponds to the marking position of the marking mechanism, thereby being able to adjust the deviation of the luggage case shell 21 in the front and back directions; after marking is completed, the blocking rod 18 retracts, and the intermittent conveyor belt 1 conveys the marked luggage case shell 21 forward. After the marked luggage case shell 21 passes through the position of the blocking rod 18, the blocking rod 18 extends towards the middle again, and at the same time conveys the next luggage case shell 21 to be marked to the marking position.

[0036] Preferred technical solution: The marking mechanism includes a laser marking head 16 and a moving mechanism. The moving mechanism includes a cross beam 10 arranged above the intermittent conveyor belt. The two ends of the cross beam 10 are connected with vertically arranged columns 11. The lower ends of the columns 11 are installed on the side of the intermittent conveyor belt 1 through a first lead screw mechanism 12 for horizontal movement. The first lead screw mechanism 12 is driven to rotate by a first motor 13. A slide rail is arranged along the cross beam 10 on one side of the cross beam 10. A mounting frame 14 is slidably matched on the slide rail. The mounting frame 14 is driven to slide along the slide rail by a second lead screw mechanism 15. The second lead screw mechanism 15 is driven to rotate by a second motor 20. The laser marking head 16 is installed on the mounting frame 14 and arranged downward.

[0037] The laser marking head 16 adopts the existing technology. The laser marking control host connected to the laser marking head 16 is arranged on one side of the intermittent conveyor belt 1 and adopts the existing technology; the mounting frame 14 is driven to move by the second screw mechanism 15, and the crossbeam 10 is driven to move by the first screw mechanism 12, so as to adjust the front, back, left and right positions of the laser marking head 16.

[0038] According to a preferred technical solution, a tip 7 is provided at the inner end of the upper surface of the separation plug, and the tip 7 extends outwardly and obliquely to form an inclined surface connected to the lower surface of the separation plug.

[0039] The thickness of the separation plug is greater than the distance between the residual edges 22 of two adjacent suitcase shells 21. When several suitcases are stacked, the suitcase shell 21 located on the upper side is buckled on the suitcase shell 21 located on the lower side. Therefore, the two adjacent suitcase shells 21 are easily clamped, which makes it difficult for the lower suitcase shell 21 to fall by gravity. According to the present solution, the separation plug is inserted between the residual edges 22 of the two suitcase shells 21 through the tip 7. During the insertion process, the two suitcase shells 21 are spread apart by the gradually increasing thickness of the separation plug, which facilitates the lower suitcase shell 21 to fall by its own gravity.
