[0002] In the production of modern chemical, food, feed, fertilizer and other industries, high-position palletizers have been increasingly used for palletizing bagged products. They are core equipment for automated logistics and warehousing scenarios, mainly through the coordinated work of mechanical structure, control system and sensors to achieve efficient stacking of goods.

[0003] The existing patent application number CN201520947857.4 is a double-line high-position palletizer. During the palletizing operation, it is impossible to flip the upside-down bags. However, in the process of standardized warehouse management, in accordance with the 5S management requirements, the unified direction of the bags can make the cargo area more visually neat and orderly. Moreover, the stacked bags face up, which makes it easier for emergency personnel to quickly identify the product name in the event of an emergency accident and shorten the handling time. Therefore, during the palletizing operation, manual intervention is required to flip the upside-down bags, which is inefficient and not conducive to production. Summary of the Invention

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0030] Example 1: Figure 1 、 Figure 2 、 Figure 4 As shown, a double-line high-speed high-position palletizer is used for bag palletizing operations. The side of the bag has a unique identification marked on the front, including: a feeding conveyor 1, a sub-packaging machine 2, a palletizing processing line 3, and a palletizing platform 4;

[0031] The feeding conveyor 1 is used to feed bags and convey the bags to the sub-packaging machine 2. Two palletizing processing lines 3 are provided. The bags sub-packed by the sub-packaging machine 2 enter the two palletizing processing lines 3 respectively. The two palletizing processing lines 3 are located on both sides of the palletizing platform 4.

[0032] The palletizing processing line 3 includes a climbing conveyor 12, a horizontal conveyor 13, and a transfer table 14;

[0033] A turning frame 21 is provided at the upper end of the climbing conveyor 12. The turning frame 21 is provided with an identifier 22 for identifying a unique identifier on the front of the bag mark. The unique identifier on the front of the bag can be a product identifier, a pattern identifier, etc. that only exists on the front. The identifier 22 is connected to the signal input end of the controller. The controller controls the start and stop of the support push rod 23. The support push rod 23 uses a non-self-locking push rod (which can be pushed out when opened and can freely retract under pressure when closed), such as SMC's MAL series single-acting cylinder. A turning bracket 24 is connected to the turning frame 21 by a hinge. The lower part of the turning bracket 24 is hinged to the self-flowing frame 25. A material receiving frame 26 is fixed to the horizontal conveyor 13. Guide grooves 27 are provided on both sides of the self-flowing frame 25. A protrusion 28 is provided on the material receiving frame 26. The protrusion 28 slides in the guide groove 27. One end of the support push rod 23 is hinged to the feed conveyor 1, and the other end is hinged to the lower end of the turning bracket 24.

[0034] The identifier 22 includes a photoelectric sensor (e.g., Omron E3Z series), an industrial camera (e.g., Basler acA series), and an industrial computer (e.g., Advantech UNO series). The photoelectric sensor is used to monitor the passage of bags and packages. The photoelectric sensor synchronously triggers the industrial camera to take pictures, transmits the image data to the industrial computer for processing and identification, and outputs the front or back judgment result in JSON format to the controller. The controller uses a Siemens S7-1200 PLC controller. The controller controls the start and stop of the support push rod 23 based on the front or back judgment result. The front control activates the solenoid valve on the support push rod 23, and the back control deactivates the solenoid valve on the support push rod 23.

[0035] The packed bags are fed by the feed conveyor 1 and guided by the subpackaging machine 2. The bags fed by the feed conveyor 1 are alternately fed into the two palletizing processing lines 3. The bags entering the palletizing processing line 3 are lifted by the climbing conveyor 12 and dropped from the top of the climbing conveyor 12 to the horizontal conveyor 13. The horizontal conveyor 13 conveys the bags to the transfer table 14 for discharge. The bags are then pushed by the transfer table 14 into the palletizing table 4 for palletizing.

[0036] During this process, when the bag enters the horizontal conveyor 13 from the climbing conveyor 12, the identifier 22 on the turning frame 21 recognizes whether there is a unique mark on the front of the bag near the identifier 22. If there is a unique mark, the controller controls the opening of the solenoid valve, and the air pump outputs airflow to the support push rod 23, so that the support push rod 23 extends. The extended support push rod 23 supports the turning bracket 24, and the bag falling from the climbing conveyor 12 can enter the gravity rack 25 from the turning bracket 24 and fall along the gravity rack 25 to the horizontal conveyor 13.

[0037] When the bag is lifted up, the support rod 23 is pulled back and the bag is lifted up, so that the bag can be put back on the conveyor belt 24. When the bag is lifted up, the support rod 23 is pulled back and the bag is put back on the conveyor belt 24. When the bag is lifted up, the support rod 23 is pulled back and the bag is put back on the conveyor belt 24. When the bag is lifted up, the support rod 23 is pulled back and the bag is put back on the conveyor belt 24.

[0038] Example 2: Based on Example 1, Figures 1-4 As shown, a leveling conveyor belt 31 is provided on the horizontal conveyor 13. The leveling conveyor belt 31 is parallel to the horizontal conveyor 13. The bags pass between the leveling conveyor belt 31 and the horizontal conveyor belt. When the bags pass through the horizontal conveyor 13, they pass between the horizontal conveyor 13 and the leveling conveyor belt 31, which can flatten the bags, improve the uniformity of material distribution inside the bags, make the bags flat during palletizing, and improve the stability of palletizing.

[0039] An arc-shaped groove 32 is provided on the flip bracket 24, and an arc-shaped push plate 33 is slidably mounted on the arc-shaped groove 32. The side of the arc-shaped push plate 33 is provided with teeth. A revolving gear 34 is rotatably mounted on the side of the flip bracket. A positioning gear 35 is fixed to the flip frame 21. The central axis around which the flip bracket 24 rotates about the flip frame 21 is coaxially arranged with the positioning gear 35. The positioning gear 35 engages with the revolving gear 34. A pusher shaft 36 is rotatably mounted on the side of the flip bracket 24. One end of the pusher shaft 36 is connected to the revolving gear 34 through a gear. A pusher gear 37 is mounted on the pusher shaft 36. The pusher gear 37 engages with the teeth on the side of the arc-shaped push plate 33.

[0040] When the bag pushes down the flip bracket 24 and causes it to deflect, the deflection of the flip bracket 24 drives the revolving gear 34 to revolve around the positioning gear 35 on the flip frame 21. The rotation of the revolving gear 34 drives the pushing shaft 36 and the unloading gear 37 to rotate, thereby pushing the arc-shaped push plate 33 out of the flip bracket 24. When the arc-shaped push plate 33 contacts the bag on the flip bracket 24, it pushes the bag to tilt toward the gravity rack 25.

[0041] When the bag is moved downwards along the guide slope, the vibration structure on the self-flowing frame 25 generates vibration, so that the material in the bag is deposited downwards under the action of its own gravity, and when the bag falls onto the horizontal conveyor 13, one end of the deposited material is located at the front end and preferentially enters the lower part of the leveling conveyor 31, thereby preventing the bag from bursting during the leveling process.

[0042] Chain shafts 41 are provided on both sides of the lower end of the flip bracket 24, and the self-flow frame 25 is rotatably mounted on the chain shafts 41. A limit gear ring 42 is fixedly mounted on the chain shaft 41. A limit shaft 47 is rotatably mounted on the self-flow frame 25. A limit gear 43 is provided at one end of the limit shaft 47, and a driven gear 44 is provided at the other end. The limit gear 43 engages with the limit gear ring 42. A limit plate 45 is slidably provided on the self-flow frame 25, and the limit plate 45 moves in a direction perpendicular to the self-flow frame 25. A limit rack 46 is fixed to the side of the limit plate 45, and the driven gear 44 engages with the limit rack 46.

[0043] When the flip bracket 24 is deflected, the gravity frame 25 is driven to rotate relative to the flip bracket 24. The gravity frame 25 rotates the limit shaft 47 thereon, which rotates under the action of the limit gear 43 and the limit gear ring 42. The driven gear 44 at the end of the limit shaft 47 pushes the limit rack 46 to move, and then pushes the limit plate 45 to extend to the upper part of the gravity frame 25. When the bag falls and contacts the gravity frame 25, the lower end of the bag is affected by the outward-extending limit plate 45, so that the lower end of the bag will not be displaced relative to the gravity plate. Combined with the push of the arc-shaped push plate 33 on the upper part of the bag, the bag is pushed to flip as a whole, thereby realizing the rotation of the bag.

[0044] Example 3: Based on Example 1, Figures 1-6As shown, the stacking platform 4 includes a platform 51, a lifting frame 52, a stacking platform 53, and a horizontal closing platform 54. The stacking platform 53 is arranged on the lifting frame 52, and the horizontal closing platform 54 is located on the upper part of the stacking platform 53. The horizontal closing platform 54 is composed of two support plates that can move horizontally relative to each other. The support plates are slidably arranged on the platform 51, and a limiting push rod 55 is provided on the platform 51. The output end of the limiting push rod 55 is fixed to a limiting frame 56, and the limiting frame 56 is located on the upper part of the horizontal closing platform 54; the discharged bags delivered by the transfer platform 14 enter the upper part of the horizontal closing platform 54, and the limiting push rod 55 is used to push the limiting frame 56 to squeeze the bags, thereby limiting the position of the bags on the horizontal closing platform 54, separating the two support plates on the horizontal closing platform 54, and the bags naturally fall onto the stacking platform 53 under the action of gravity. As the lifting frame 52 drives the stacking platform 53 to descend, the palletizing operation of the bags is completed;

[0045] A horizontal slide 61 is provided on the upper part of the transfer table 14, and a pusher 62 is installed on the sliding part of the horizontal slide 61. The horizontal slide 61 drives the pusher 62 to move relative to the stacking table 4; the horizontal slide 61 drives the pusher 62 on the transfer table 14 to move, and the bags arranged on the transfer table 14 are pushed into the stacking table 4;

[0046] The limit push rod 55 and the limit frame 56 are respectively provided with two groups. The limit frame 56 is fixedly installed on the output end of the limit push rod 55 one by one. The limit push rod 55 pushes the limit frame 56 to move in a direction perpendicular to the moving direction of the horizontal slide 61. A reciprocating screw rod 63 is rotatably installed on the limit frame 56. A cooperative gear 64 is provided at one end of the reciprocating screw rod 63. A guide rack 65 parallel to the stroke of the limit push rod 55 is provided on the platform 51. The cooperative gear 64 engages the guide rack 65. A lateral block frame 66 is slidably installed on the moving part of the reciprocating screw rod 63. A limit spring 67 is provided between the two ends of the lateral block frame 66 and the moving part. The spring 67 exerts a force on the lateral stopper 66 to ensure that both ends of the lateral stopper 66 are evenly displaced and the lateral stopper 66 is perpendicular to the limit frame 56; when the limit push rod 55 pushes the limit frame 56 to move, the limit frame 56 moves along the guide rack 65. As the limit frame 56 moves along the guide rack 65, the coordinated gear 64 thereon drives the reciprocating screw 63 to rotate and then drives the lateral stopper 66 to move along the axis of the reciprocating screw 63. Thus, the rectangular structure formed by the lateral stopper 66 and the limit frame 56 is used to limit and aggregate the arranged bags pushed into the transfer table 14, so as to prevent the arranged bags from being dispersed when falling and stacking;

[0047] The lower part of the lateral retaining frame 66 is connected to the side fence frame 68 by a hinge, and a limit block 69 is provided on the lateral retaining frame 66. The limit block 69 is located at the hinge point of the lateral retaining frame 66 and the side fence frame 68. The limit block 69 limits the side fence frame 68 from deflecting toward the outside of the stacking platform 4; when the pushing frame 62 pushes the arranged bags into the stacking platform 4, at this time, the limit push rod 55 contracts, and the rectangle enclosed by the lateral retaining frame 66 and the limit frame 56 is in the largest area position. At this time, the pushing frame 62 pushes the arranged bags from the side fence frame 68 into the stacking platform 4 When the material return rack pushes the bag to contact the side fence 68, it drives the side fence 68 to deflect toward the inside of the stacking platform 4, and the bag enters the stacking platform 4 from the lower part of the side block 66. When the material return rack exits the stacking platform 4, the side fence 68 deflects and resets under the action of its own gravity. Then, under the action of the limit push rod 55, the side block 66 and the limit frame 56 are driven to move. The limit block 69 on the side block 66 limits the outward deflection of the side fence 68. When the side fence 68 contacts the bag, it can form an extrusion limit for the bag.
