Description

Technical Field

[0001] The invention relates to the technical field of material transportation, and in particular to an automatic material grabbing device for material handling equipment. Background Art

[0002] Cement is a kind of material. It is a powdery hydraulic inorganic gelling material. It becomes a slurry after adding water and stirring. It can harden in the air or in water, and can firmly glue sand, stone and other materials together. The early mixture of lime and volcanic ash is very similar to the modern lime volcanic ash cement. It is used to glue the concrete made of crushed stone. After hardening, it not only has high strength, but also can resist the erosion of fresh water or salt water. For a long time, it has been widely used in civil construction, water conservancy, national defense and other projects as an important cementing material. In the old days, cement was also called cement cement. When cement is transported, it is generally transported in bags. The bagged cement is stacked on the stacking board in an orderly manner and transported to the truck for transportation through handling equipment (such as a gantry). The grabbing mechanism is a component on the handling equipment.

[0003] When the existing grabbing mechanism is in use, when grabbing bags of cement, it is generally lifted and lowered to grab one bag at a time. Even if the cement bags are grabbed at multiple stations, they must be lifted and lowered repeatedly to complete the grabbing of the cement bags, which makes the grabbing speed of the cement bags slow and reduces the handling efficiency of the cement bags. In addition, when the existing grabbing mechanism is in use, when the cement is stacked in the truck compartment, the stacked cement bags cannot be squeezed and sorted, so that the cement bags become compact with each other, so that the cement bags are relatively loose during transportation, and the cement bags are easy to tip over during bumps, which can easily cause accidents. Therefore, the present invention designs several structures to solve the problems of slow grabbing speed of cement bags and inability to squeeze and sort the stacked cement bags to make the cement bags compact with each other. In view of the above problems, the inventor proposes an automatic grabbing device for material handling equipment to solve the above problems. Summary of the invention

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] 1. By setting the adjusting mechanism and the material grabbing mechanism, the present invention enables the adjusting mechanism to drive the material grabbing mechanism to work, grab bagged cement, so that the device can lift and grab multiple bags of cement at one time, accelerating the grabbing speed of cement and improving the handling efficiency of bagged cement.

[0012] 2. The present invention utilizes the elongation of the air cylinder to drive the top plate to move downward, and further drives the two fixed plates to move downward, so that the bagged cement stacked in a column continuously pushes open multiple pairs of material-grabbing plates and enters between the two fixed plates until a set number of bagged cement enters between the two fixed plates.

Thus, it moves upward together with the upward movement of the two fixed plates, so that the material-grabbing device does not need to be lifted and lowered multiple times, and only needs to be lifted and lowered once to grab multiple bags of cement.

[0013] 3. The present invention utilizes the self-rotation of the second rotating shaft to drive the first incomplete gear and the second incomplete gear to rotate, and further drives the fourth incomplete gear to rotate, and then drives the fourth rotating shaft to rotate, and then drives the turntable and the round block to rotate, and then drives the sorting plate to move downward by a set distance; utilizes the multiple repeated self-rotation of the third connecting shaft to drive the second helical gear to rotate repeatedly, and then drives the second screw rod to rotate repeatedly, and then drives the second moving seat to move repeatedly, and then drives the sorting plate to move repeatedly along the horizontal direction, and beats and squeezes the cement stacked in the truck carriage repeatedly, so that the bagged cement in the truck carriage is stacked more compactly.

[0029] The material grabbing mechanism 4 and the arranging mechanism 5 are both connected to the mounting plate 1 .

[0030] Working principle: When the device is needed to transport the stacked bags of cement, the grabbing device is installed on a matching transport device (such as a gantry) so that the two fixed plates 410 are located on both sides directly above the stacked bags of cement. The multiple cylinders 217 are started to extend at the same time, driving the top plate 201, the first end plate 202 and the second end plate to move downward, thereby driving the two fixed plates 410 to move downward, so that the bags of cement stacked in a row continuously push the multiple pairs of grabbing plates 409 and enter between the two fixed plates 410 until the set number of grabbing plates 409 is reached. When the bagged cement enters between the two fixed plates 410, the cylinder 217 is activated to shorten it, driving the two fixed plates 410 to leave the bagged cement pile. Due to the effect of gravity, the bagged cement between the two fixed plates 410 wants to remain stationary, but the two corresponding grab plates 409 are deeply stuck on both sides of the cement bag, and the cement bag cannot be separated from between the two grab plates 409. Therefore, it moves upward together with the upward movement of the two fixed plates 410, so that the grab device does not need to be lifted multiple times, and only needs one lift to grab multiple bags of cement.

[0031] The second motor 204 is started to rotate, driving the first connecting shaft 205 to rotate, thereby driving the two first screws 207 to rotate around the first connecting shaft 205 and the second connecting shaft 206, respectively, thereby driving the first moving seat 208 to move in the front-rear direction, and moving the bagged cement grabbed by the grab plate 409 to a specific position above the truck compartment;

[0032] Start the first motor 303 to rotate it 90 degrees clockwise, thereby driving the second rotating shaft 304 to rotate 90 degrees by itself, and then driving the first incomplete gear 305 and the second incomplete gear 306 to rotate 90 degrees with the second rotating shaft 304 as the axis (during this process, the first incomplete gear 305 does not mesh with the third incomplete gear 307), and then driving the fourth incomplete gear to rotate 180 degrees with the third sleeve as the axis. Through the transmission of the first synchronous belt and the synchronous pulley, drive the fourth rotating shaft 503 to rotate 180 degrees by itself, and then drive the turntable 504 and the round block 505 to rotate 180 degrees with the fourth rotating shaft 503 as the axis, and then drive the annular strip 506 and the sorting plate 508 to move downward by a set distance. Start the first motor 303 again to rotate it 90 degrees clockwise again (during this process, the first incomplete gear 305 meshes with the third incomplete gear 307 and drives the third incomplete gear 307 to rotate), and then drive the first sleeve 308 to rotate by itself, and then drive the two first cylindrical gears 309 to rotate with the fixed shaft 314 and the third rotating shaft 310 as the axes respectively, and then drive the two second cylindrical gears 313 to rotate with the third rotating shaft 310 and the first rotating shaft 402 as the axes respectively, and then drive the first rotating shaft 402 to rotate by itself, and then drive the rotating plate 403 to rotate with the first rotating shaft 402 as the axis, and then drive the two connecting rods 404 to move along the set track, and then push the two first moving plates 405 to move a set distance in the direction away from each other, and then drive the second moving plates 406, the moving strips 407, the connecting strips 408 and the material grabbing plates 409 on both sides to move a set distance in the direction away from each other, so that the material grabbing plates 409 no longer grab the bagged cement. Under the action of gravity, the bagged cement falls downward to the truck carriage in turn, thus completing the handling of the stacked bagged cement onto the truck carriage;

[0033] Start the third motor 215 to rotate it repeatedly for multiple times, thereby driving the third connecting shaft 216 to rotate repeatedly by itself, and then driving the second helical gear 213 to rotate repeatedly with the third connecting shaft 216 as the axis, and then driving the first helical gear 212 to rotate repeatedly with the transmission shaft 218 as the axis, and then driving the second screw rod 210 to rotate repeatedly with the transmission shaft 218 as the axis, and then driving the second moving seat 211 to move repeatedly, and then driving the sorting plate 508 to move horizontally repeatedly, so as to repeatedly pat and squeeze the cement stacked in the truck carriage, making the bagged cement in the truck carriage stack more compactly;

[0034] Start the first motor 303 to reverse it twice by 90 degrees, so that structures such as the material grabbing plates 409 and the sorting plates 508 return to their original positions, preparing for the next handling operation of the bagged cement.

[0035] Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
