Description

TECHNICAL FIELD

[0001] The present application relates to a kind of palletizing mechanism, in particular to a kind of automatic palletizing mechanism of bagged material. BACKGROUND

[0002] In modern industrial production, the palletizing operation of bagged material as the key link of logistics warehousing and production line, its automation degree directly affects production efficiency and cost control. With the scale development of food, chemical industry, building materials and other industries, higher requirements are put forward to the efficiency, reliability and material protection of bagged material palletizing equipment. At present, the bagged material palletizing mechanism on the market mainly adopts the automation solution of mechanical arm cooperating with clamping device, however this kind of traditional technology still has significant defects in practical application.

[0003] The existing palletizing mechanism adopts swing clamping type loading mode, and the bagged material is grabbed by the opening and closing of the clamping arms on both sides.

[0027] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0028] Embodiment one: please refer to Figure 1 A kind of automatic bagged material stacking mechanism, including support beam 1 and two parallelly arranged cross beams 2, support beam 1 is fixedly connected below cross beam 2, cross beam 2 is slidably connected with horizontal moving slider 3, two horizontal moving sliders 3 are fixedly connected with guide beam 4 between, guide beam 4 is slidably connected with lifting assembly 5, lifting assembly 5 is connected with horizontal base plate 7 below by sling 6, horizontal base plate 7 is provided with stacking assembly 8, stacking assembly 8 includes two horizontal close or far away support plates 9.

[0029] Support beam 1, cross beam 2, horizontal moving slider 3 and guide beam 4 are directly installed in factory building, when needing to be stacked, lifting by lifting assembly 5, stacking by stacking assembly 8, the two opposite moving support plates 9 in stacking assembly 8 can realize the loading and unloading operation of material. In order to facilitate the loading and unloading of support plate 9, the upper surface of support plate 9 can be set to the state of being inclined to the middle, so that the bagged material can be stacked when the support plate 9 moves outward. The packaging bag of the material in this state needs strong structural strength to avoid damage to the packaging bag.

[0030] The first motor 10 is fixedly connected to the transverse sliding block 3 and drives the transverse sliding block 3 to move. The first motor 10 drives the transverse sliding block 3 to move transversely. The technical means is the prior art in the field, and a roller can be directly connected to the motor shaft of the first motor 10. The outer edge of the roller abuts against the cross beam 2, so that the transverse sliding block 3 is driven to move transversely as a whole when the first motor 10 rotates.

[0031] Please refer to Figure 2 , the lifting assembly 5 comprises a sliding base plate 11 slidably connected to the guide beam 4. The sliding base plate 11 is fixedly connected with a support vertical plate 12. The support vertical plate 12 is rotatably connected with two lifting shafts 13 on the outer side. The lifting shafts 13 are fixedly connected with lifting gears 14 on the outer side. The transmission ratio between the lifting gears 14 is 1:1. Each lifting shaft 13 is fixedly connected with two spools 15 on the outer side. The lifting ropes 6 are provided with four and are fixedly connected to the outer side of different spools 15. The lower end of the lifting ropes 6 is fixedly connected to the four corners of the horizontal base plate 7. One end of one of the lifting shafts 13 is fixedly connected with a second motor 16.

[0032] The lifting assembly 5 realizes the lifting function by starting and stopping the second motor 16. The second motor 16 controls the up and down of the sliding base plate 11 by positive and negative rotation. When the second motor 16 rotates, it first drives the lifting shaft 13 connected thereto to rotate. At the same time, based on the meshing of the lifting gears 14, the other lifting shaft 13 rotates at the same speed in the opposite direction. The four spools 15 will rotate at the same time, and the lifting ropes 6 will move upward or downward under the driving force of the second motor 16.

[0033] Four through holes 17 are formed in the sliding base plate 11. The lifting ropes 6 pass through different through holes 17 and are connected to the horizontal base plate 7. The through holes 17 can guide the lifting ropes 6 to a certain extent, avoiding the winding of the lifting ropes 6 outside the spool 15 during winding.

[0034] One of the transverse sliding blocks 3 is fixedly connected with a third motor 18. The rotor of the third motor 18 is fixedly connected with a drive screw 19. The sliding base plate 11 is fixedly connected with a connecting lug 20. The drive screw 19 is threadedly connected with the connecting lug 20. The third motor 18 drives the drive screw 19 to rotate during rotation. The drive screw 19 drives the connecting lug 20 to move. The moving direction is controlled by the rotation direction of the third motor 18. The control can adjust the position of the lifting assembly 5, which is convenient for moving to the top of the bagged materials to be stacked.

[0035] Please refer to Figure 3 , Figure 4 and Figure 5, the code pile assembly 8 further comprises electric telescopic rods 21 symmetrically arranged on both sides of the horizontal base plate 7, the end of the electric telescopic rod 21 is fixedly connected with a driving rack 22, two positioning gears 23 are rotatably connected on both sides of the horizontal base plate 7, the positioning gears 23 are respectively engaged with both sides of the driving rack 22, a swing rod 24 is fixedly connected below each positioning gear 23, a transmission groove 25 is formed in the bottom of the swing rod 24, and the supporting plate 9 is driven to approach or move away through the transmission groove 25. Two fixed rods 26 are arranged on the same side of the supporting plate 9, one of the two fixed rods 26 is slidably connected with the transmission groove 25, and the four fixed rods 26 on the same side of the two supporting plates 9 are located at the same height, and a positioning groove-shaped piece 27 is sleeved outside the four fixed rods 26.

[0036] The code pile assembly 8 is driven by the electric telescopic rod 21, the electric telescopic rod 21 drives the driving rack 22 to move up and down during the telescopic process, the driving rack 22 drives the positioning gears 23 on both sides to rotate during the up-and-down movement, and the positioning gears 23 drive the swing rods 24 to swing during the rotation. Since the swing rods 24 on both sides are symmetrically rotated, the supporting plate 9 is driven to move outward synchronously and symmetrically, and when the electric telescopic rod 21 is retracted, the supporting plate 9 is simultaneously moved inward. Since the horizontal state is close or away from each other, the included angle between the supporting plate 9 and the packaging bag is relatively small, which can effectively avoid damaging the packaging bag. After the packaging bag is moved to the stacking position, the electric telescopic rod 21 is pushed out, and then the supporting plate 9 is opened, and the packaging bag falls to be stacked. The four fixed rods 26 are fixed with the corresponding supporting plate 9, and the rotation degree of freedom of the supporting plate 9 is limited by the positioning groove-shaped piece 27, so that the supporting plate 9 is prevented from swinging.

[0037] In addition, other connection modes can also be used to realize the purpose of driving the supporting plate 9 to move horizontally through the transmission groove 25. For example, a telescopic rod that can slide horizontally is arranged below the horizontal base plate 7, and the lower end of the telescopic rod is fixedly connected with the supporting plate 9. At this time, when the supporting plate 9 moves outward, it will only move horizontally.

[0038] Embodiment two: the embodiment is based on the previous embodiment and further discloses the following technical content: please refer to Figure 4 and Figure 6 A plurality of air vents 28 are formed in the bottom of the supporting plate 9, a plurality of rotating shafts 29 are uniformly distributed and rotatably connected in the air vents 28, and the rotating shafts 29 are exposed to the outside of the air vents 28.

[0039] Through the structural arrangement of the embodiment, the packaging bag can be more easily slid onto the supporting plate 9, and in addition, the packaging bag can be moved to the stacking position. If the mass of the packaging bag is too large and cannot be easily dropped, a tool can be used to easily push the packaging bag down.

[0040] Working principle: support beam 1, beam 2, horizontal moving slider 3 and guide beam 4 are directly installed in the factory building. When stacking, the lifting assembly 5 lifts the material, and then the stacking assembly 8 completes the stacking operation. The two supporting plates 9 of the stacking assembly 8 move towards each other to realize the loading and unloading of the material. In order to facilitate loading and unloading, the upper surface of the supporting plate 9 can be designed to be inclined towards the middle, and the bagged material is stacked when it moves outward, but this requires the packaging bag to have high structural strength.

[0041] The lifting assembly 5 relies on the second motor 16 to realize the lifting function. The second motor 16 controls the up and down movement of the sliding base plate 11, and when the motor rotates, it drives the lifting shaft 13 to rotate, and through the meshing of the lifting gear 14, the other lifting shaft 13 rotates in the opposite direction at the same speed, and the four spools 15 rotate synchronously, so that the lifting rope 6 realizes lifting.

[0042] The stacking assembly 8 is driven by the electric telescopic rod 21, and the telescopic rod drives the driving rack 22 to move up and down, and then drives the positioning gear 23 to rotate, and the positioning gear 23 drives the swing rod 24 to swing. Because the two swing rods 24 rotate symmetrically, the supporting plates 9 also move symmetrically and synchronously to the outside or inside. The convergence and divergence in the horizontal state reduces the included angle with the packaging bag and avoids damaging the packaging. When the packaging bag moves to the stacking position, the electric telescopic rod 21 is pushed out, the supporting plate 9 is opened, and the material falls to complete the stacking. The four fixed rods 26 are fixed to the corresponding supporting plates 9, and the rotation of the supporting plates 9 is limited by the positioning groove 27.

[0043] It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.

[0044] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.
