Description

Technical Field

[0001] The utility model belongs to the field of plate stacking machines, in particular to a novel plate stacking machine for a building block production line. Background Art

[0002] A block / cement brick stacking machine is a piece of machinery used in the block / cement brick production process. It is primarily used to automatically stack finished cement brick pallets. In a cement brick production line, pallets are used to support the bricks. Once the bricks are formed and have reached a certain strength, the pallets need to be separated from the bricks, collected, and stacked for subsequent recycling. The cement brick stacking machine utilizes a robotic arm, conveyor, and other components to work together.

[0003] Existing patent CN205953057U discloses a stacking machine for a block production line. The machine comprises a slide rail and a bracket, to which a lifting frame is slidably connected. The bracket is equipped with a travel motor and a lifting motor. Clamping mechanisms are provided on either side of the lifting frame. The clamping mechanisms comprise a movable frame with its upper end rotatably connected to the lifting frame and a clamping cylinder with a cylinder body fixedly connected to the lifting frame. The piston rod of the clamping cylinder is rotatably connected to the movable frame at the middle of the movable frame, and a claw is provided at the lower end of the movable frame. This stacking machine allows the movable frame to rotate relative to the lifting frame by providing the clamping cylinder, allowing the claw to clamp the pallet. However, in actual use, a problem arises: the span of the gripping node of the claw is large, while the pallet is generally thin. This makes it easy for the blocks / cement bricks to deform the pallet during transfer, which not only affects the service life of the pallet but also the stability of the blocks and the stacking effect.

[0022] To more clearly understand the above-mentioned objects, features, and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein may be combined with each other unless they conflict. For ease of description, the words "upper," "lower," "left," and "right" appearing below merely indicate the same directions as in the drawings themselves and do not limit the structure.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Examples, such as Figure 1 As shown in FIG. 7 , the present invention provides a novel stacking machine for a block production line, comprising a portal frame 1. Multiple pairs of movable pulleys 2 are disposed at the bottom of the portal frame 1. A power motor 3 is disposed at the top of the frame, and a chain drive mechanism 4 is provided on the power output side of the power motor 3. The portal frame 1 can be moved forward and backward along the floor rails within a workshop or factory building via the movable pulleys 2. The portal frame 1, movable pulleys 2, power motor 3, and chain drive mechanism 4 are well-established technologies and will not be further described in detail in this embodiment. On this basis, in order to improve the transfer performance of the pallet and the building blocks, the utility model starts from changing the gripping direction, and the proposed chain transmission mechanism 4 is provided with a lifting mechanism 5 in its transmission direction that is coordinated with the portal frame 1. The lifting mechanism 5 is provided with a flipping gripping mechanism 6 at both ends of the moving direction toward the moving pulley 2. The flipping gripping mechanism 6 includes a flipping drive cylinder 61 rotatably connected to the lifting mechanism 5, and a flipping arm 62 is provided at the telescopic end of the flipping drive cylinder 61. The flipping arm 62 is provided with a flipping shaft 63 at the end away from the flipping drive cylinder 61. The two ends of the flipping shaft 63 are connected to the lifting mechanism 5, and the flipping shaft 63 is provided with two gripping arms 64 near its two ends. The gripping arm 64 is driven by the flipping drive cylinder 61 to flip toward the lifting center direction of the lifting mechanism 5.

[0025] Specifically, the flip gripping mechanism 6 serves as the executive mechanism for clamping the pallet of this device. It changes the previous design of clamping the pallet from both sides of the portal frame 1, and instead clamps the pallet from the front and rear ends of the portal frame 1 in the direction of movement. The flip drive cylinder 61 drives the flip arm 62 to make a planar motion. The flip arm 62 flips around the flip axis 63 and the axial connection center of the lifting mechanism 5, thereby driving the gripping arm 64 to flip toward the lifting center direction of the lifting mechanism 5. The bottom of the gripping arm 64 clamps the pallet through the convex teeth, and the chain transmission mechanism 4 drives the lifting mechanism 5 to produce a lifting action. In conjunction with the forward and backward movement function of the portal frame 1, the pallet and the building block can be transferred, that is, the plate stacking action can be achieved. In this way, the clamping node is changed from the length direction of the pallet to the width direction of the pallet. By changing the gripping direction of the pallet, the span of the gripping node of the same pallet can be shortened, and the physical force arm of the pallet's gravity can be shortened, which is beneficial to improving the pallet's anti-deformation ability and ensuring the flatness of the pallet during the transfer process and the stability of the building block.

[0026] In order to improve the stacking efficiency of this equipment, the present invention can transfer two pallets and the blocks located on the pallets at one time. Specifically, the lifting mechanism 5 provided by the present invention is provided with a connecting rod clamping mechanism 7 in the middle, and the connecting rod clamping mechanism 7 includes a pair of vertical clamping shafts 71, and the bottom of the clamping shafts 71 is provided with bottom claws 72, and the radial length of the bottom claws 72 is greater than the axial diameter of the clamping shafts 71. The tops of the two clamping shafts 71 are provided with two parallel connecting rod arms 73, and the ends of the connecting rod arms 73 are provided with T-shaped connecting rods 74. The middle of the T-shaped connecting rod 74 is provided with a connecting rod drive cylinder 75, and the fixed end of the connecting rod drive cylinder 75 is connected to the lifting mechanism 5. The distribution span of the two flip gripping mechanisms 6 is designed to be slightly larger than twice the width of the pallets. The two flip gripping mechanisms 6 clamp the pallets from both sides of the two pallets. After the connecting rod drive cylinder 75 drives the T-shaped connecting rod 74 and the clamping shaft 71 to move in a plane, the bottom claw 72 at the bottom of the clamping shaft 71 can rotate 90 degrees. The two ends of the bottom claw 72 support the pallet from the gap between the two pallets and form a clamping relationship with the gripping arm 64, thereby achieving clamping of the two pallets. Therefore, by adopting the connecting rod clamping mechanism 7 to provide multiple clamping fulcrums, the two sets of flip gripping mechanisms 6 can be used to grasp two side-by-side pallets, which is conducive to improving the stacking efficiency of the equipment and the actual utilization rate of the equipment.

[0027] To improve the utilization rate of the lifting mechanism 5, the lifting mechanism 5 provided by the present invention includes a top frame 51, the end of which is used to mount a tilting shaft 63. A pair of side frames 52 are provided at the bottom of the top frame 51. Both ends of the side frames 52 are provided with lifting rollers 53 that roll with the inner side of the portal frame 1. The lifting rollers 53 and the portal frame 1 can achieve a vertical guiding effect, which is conducive to ensuring the stacking effect of the equipment after continuous stacking. At the same time, an intermediate frame 54 is provided between the side frames 52. The intermediate frame 54 is used to support the tilting drive cylinder 61 and the connecting rod clamping mechanism 7. Among them, the top frame 51, the side frames 52, and the intermediate frame 54 are all constructed of elements using square tubes as units, which have good structural strength, good support performance, high stability, and long service life.

[0028] In order to improve the transmission performance of the chain drive mechanism 4, the chain drive mechanism 4 provided by the present invention includes a driving sprocket 41 provided at the output end of the power motor 3, two transmission shafts 42 distributed on both sides of the driving sprocket 41 are provided on the top of the portal frame 1, and driven sprockets 43 are provided at both ends of the transmission shaft 42. The driving sprocket 41 and the driven sprocket 43 are connected by a first transmission chain 44. A coaxial sprocket 45 is provided on one side of the driven sprocket 43. A positioning sprocket 46 connected to the portal frame 1 is provided below the coaxial sprocket 45. The positioning sprocket 46 and the coaxial sprocket 45 are connected by a second transmission chain 47. A lifting connector 48 is provided on the second transmission chain 47, and the lifting connector 48 is connected to the lifting mechanism 5. Among them, the power motor 3 can be provided with two sets, and the driving sprocket 41, the driven sprocket 43, the coaxial sprocket 45, the positioning sprocket 46, and the first transmission chain 44 and the second transmission chain 47 are all two sets. The two transmission paths transmit the lifting mechanism 5 from both sides. The power motor 3 receives power from the driving sprocket 41. The driving sprocket 41, the first transmission chain 44, and the two transmission shafts 42 form a triangular transmission connection to ensure smooth transmission of force from the transmission shafts 42. The coaxial sprocket 45 on the transmission shaft 42 rotates synchronously with the driven sprocket 43. The coaxial sprocket 45, the second transmission chain 47, and the positioning sprocket 46 form a second transmission direction. The lifting connector 48 connected to the second transmission chain 47 can carry the lifting mechanism 5 up and down synchronously, thereby achieving an effective lifting transmission action.

[0029] To improve the practicality of the lifting connector 48, the lifting connector 48 provided by the present invention includes two relatively connected slot plates 481, wherein the back of one slot plate 481 is connected to the second transmission chain 47 via a pin, and the other slot plate 481 is connected to the lifting mechanism 5 via screws. The pins can be pins on the chain links, and pins are ejected from the pin joints of adjacent chain links. A longer pin or two identical pins are used to pin the slot plates 481 to the chain links, thereby establishing a connection between the slot plates 481 and the chain links. After the other slot plate 481 is connected to the side frame 52 of the lifting mechanism 5, the lifting mechanism 5 can be raised and lowered with the movement of the second transmission chain 47.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
