Description

Technical Field

[0001] The utility model relates to the field of lighter production equipment, in particular to a lighter casing transportation and tray loading production line. Background Art

[0002] At present, on the lighter production line, the lighter casing needs to be sent to the upper brace station for processing through a conveying device. The existing casing conveying device lacks a cleaning mechanism, and dust and impurities remain on the casing, affecting subsequent processing stations, resulting in poor product quality and low production efficiency.

[0003] On the lighter production line, the delivered casings are sent to the next workstation through a grabbing device, and some casings will not be grabbed. The existing processing method is to place a collection box at the discharge end of the conveyor. After collection, the staff will carry them to the feed end of the conveyor to reload them. This collection method has high labor intensity and low efficiency.

[0004] On the lighter production line, the lighter casing needs to be sent to the upper brace station via a conveyor. Since the upper brace station adopts an automated upper brace mechanism, the casings sent must be arranged neatly and enter the upper brace mechanism for processing in turn. The casings sent by the existing casing conveyor are not arranged neatly and cannot be adapted to the automated upper brace mechanism.

[0005] On the lighter production line, the lighter casing needs to be sent to the upper brace station via a conveyor. Since the upper brace station adopts an automated upper brace mechanism, the conveyed casings must be arranged neatly and enter the upper brace mechanism for processing in turn. During transportation, a special grabbing device is required to transfer the casing in the upper conveyor to the arrangement conveyor below. There is a lack of a guiding device between the two conveyors, and the casing falls directly onto the arrangement conveyor. Due to the large drop, it is easy to be misaligned and block the arrangement conveyor. The blocked casing needs to be removed manually, resulting in low factory production efficiency.

[0006] On the lighter production line, the lighter casing needs to be sent to the upper brace station by a conveyor. Since the upper brace station adopts an automated turntable upper brace mechanism, the casing sent by the conveyor is in a horizontal position, and there is a lack of an upper disk device that can automatically adjust the casing from a horizontal state to a vertical and sequentially placed state.

[0061] Embodiment 1: The staff pours the injection-molded lighter casing into the storage box 1. Since the inner bottom surface of the storage box 1 is an inclined surface, the casing is concentrated in the lifting groove 6 under the action of gravity, and the casing in the lifting groove 6 is continuously conveyed upward by the lifting conveyor 2. The casing is output from the discharge end of the lifting conveyor 2, enters the connecting box 8, and then falls on the inclined guide plate 9. After being guided by the inclined guide plate 9, it falls into the horizontal conveyor 3 under the action of gravity. When the casing falls, it is diverted by the dividing plate 10 so that the casing enters a pair of dividing conveyors evenly. When the casing is conveyed on the pair of dividing conveyors, the dust or impurities on the casing are horizontally brushed by the bristles of the roller brush conveyor 4, and the dust or impurities on the casing are longitudinally brushed by the cleaning brush roller 5. After cleaning, the casing is sent to the discharge end by the horizontal conveyor 3, and the casing is adsorbed and grasped by the adsorption and grasping device located above the horizontal conveyor 3 and then rotated to a specified angle so that the casing becomes vertical and enters the upper braces station. The excess casings sent by the horizontal conveyor 3 fall into the return material collection box 13 from the discharge end of the horizontal conveyor 3, and then fall into the feed port of the return material conveyor 11 under the action of gravity. The return material conveyor 11 sends the casing to the return material chute 12, and then falls into the lifting trough 6 after being guided by the return material chute 12, and is transported upward again through the lifting conveyor 2, so that the casing can be circulated and transported.

[0062] After the casing delivered by the horizontal conveyor 3 is preliminarily arranged, the casing of the lighter is conveyed to the bottom of the lifting suction cup mechanism 22 by the horizontal conveyor 3, the horizontal slide 23 drives the vertical slide 24 to move above the casing, the vertical slide 24 drives the steering motor 25 to descend, and the casing is sucked by the vacuum suction cup 26, and then the vertical slide 24 is raised and reset, the steering motor 25 drives the casing to rotate a specified angle, so that the casing is parallel to the horizontal conveyor 3, the horizontal slide 23 drives the casing to move above the feeding end of the arrangement conveyor 20, the vertical slide 24 drives the casing to descend, the vacuum suction cup 26 contacts and adsorbs, so that the casing falls on the arrangement conveyor 20, and a pair of lifting suction cup mechanisms 22 can grab the casing at the same time, and place a pair of casings on the arrangement conveyor 20. The casing entering the arrangement conveyor 20 is limited in conveying height by the height limit rod 27, so that the casing is arranged in sequence and sent to the upper brace station by the arrangement conveyor 20.

[0063] When the delivered casings are arranged in a disorderly manner, the existing visual inspection system is used in the transfer device, which can make the lifting suction cup mechanism 22 more accurate in grabbing the casings. The visual inspection system is composed of an industrial control computer 200, a pair of industrial cameras 201, an image acquisition card and an execution control mechanism. The industrial camera 201 takes pictures of the casings on the conveying surface of the horizontal conveyor 3, and the pictures are stored in the image acquisition card and then sent to the industrial control computer 200. Only the display screen of the industrial control computer 200 is drawn in the attached figure. The industrial control computer 200 identifies the state of the casing according to the photographed picture, and then controls the grabbing position of the lifting suction cup mechanism 22 through the execution control mechanism. After grabbing the casing, the rotation angle of the steering motor 25 is controlled according to the casing offset angle to make the casing parallel to the horizontal conveyor 3, and then the casing is placed on the arrangement conveyor 20 for transportation.

[0064] The lighter casing is sent to the discharge end of the horizontal conveyor 3, and the casing is sucked and lifted by the lifting suction cup mechanism 22, and then placed on the pouring plate 31. The piston rod of the unloading cylinder 32 is retracted, and the spring 35 is stretched. The transmission block 34 is driven to rotate through the spring 35, so that a pair of pouring plates 31 are opened downward synchronously, and the casing slides down along the pouring plate 31 under the action of gravity to be arranged in sequence on the arrangement conveyor 20. After a single unloading is completed, the piston rod of the unloading cylinder 32 is extended and reset with the assistance of the tension force of the spring 35. The pouring plate 31 rotates upward to a horizontal position, and the inclined surface of the pouring plate 31 contacts the hypotenuse of the triangular raised portion of the limit strip 36, and the raised position of the pouring plate 31 is limited by the triangular raised portion, so that the pouring plate 31 remains horizontal.

[0065] The limiting strip 36 can be detachably mounted by a nut for easy replacement.

[0066] The lighter casing is transported to the discharge end of the arrangement conveyor 20, the piston rod of the horizontal push cylinder 40 extends, and the casing is pushed into the horizontal casing accommodating groove 45 of the feed tray 42 through the rectangular push block, and then the feed tray 42 drives the casing to rotate to a vertical position together, and the piston rods of the push cylinder 43 and the protective cylinder 52 extend at the same time, and the push cylinder 43 pushes the casing on the top of the feed tray 42 into the groove limiter 48 through the push plate 46, and at the same time the protective plate 53 blocks the avoidance port 50, so that a U-shaped guiding area is formed in the groove limiter 48, and the casing falls into the vertical placement groove 47 below along the groove limiter 48 under the action of gravity. At this time, the piston rods of the push cylinder 43 and the protective cylinder 52 are retracted, the avoidance port 50 is opened, and the rotating disk 44 rotates a specified angle to drive the casing into the upper brace station. When the push-out cylinder 43 pushes the casing, the casing is pre-towed from the rear by the L-shaped anti-drop plate 51 to prevent the casing from tipping over when being pushed.
