Description

Technical Field

[0001] The invention belongs to the technical field of cargo loading, unloading and storage, and in particular relates to an online loading and unloading system for block cargo. Background Art

[0002] During the transportation of goods on the production line, if the downstream equipment fails or has insufficient processing capacity, the goods will be piled up on the production line, causing the entire production line to stop operating, affecting production efficiency. At the same time, some semi-finished products may be scrapped, causing great waste. In order to solve this problem, the existing method is to add bypass conveying equipment to the production line. When the downstream equipment fails or has insufficient processing capacity, the bypass conveyor is started to transport the goods to the bypass conveyor. After the equipment is restored, the goods on the bypass conveyor are transported back to the production line. This method has limited storage capacity, requires a longer bypass conveyor, occupies more factory space, and is difficult to layout equipment. Summary of the invention

[0003] The purpose of the present invention is to provide an online loading and unloading system for block cargo, which is used for caching block cargo on the production line, solving the backlog caused by downstream equipment failure on the production line, avoiding shutdown of the entire production line, and improving storage efficiency and storage space utilization.

[0004] The present invention discloses an online loading and unloading system for block cargo, comprising a horizontal conveyor, a grabbing device, a storage device, a rack, The horizontal conveyor is connected to the production line as a conveying equipment of the production line. The bulk goods are transported on the horizontal conveyor. A clamping mechanism is arranged at the front end of the horizontal conveyor. When the downstream equipment needs to suspend the supply of goods, the clamping mechanism clamps the goods in transport and blocks the goods in transport on the horizontal conveyor with the clamped goods; the storage device includes a storage box and an elevator for transporting the storage box, an upper conveyor, a lower conveyor, an upper transport mechanism, and a lower transport mechanism. The storage box is used to store bulk goods. The upper conveyor and the lower conveyor are arranged in parallel. On one side of the elevator, the elevator and the upper conveyor are connected by an upper transport mechanism to achieve the exchange of storage boxes, and the elevator and the lower conveyor are connected by a lower transport mechanism to achieve the exchange of storage boxes, and the storage boxes are loaded and unloaded on the elevator; the grabbing device grabs the goods blocked on the horizontal conveyor and loads them into the storage box on the elevator during loading, and grabs the goods in the storage box on the elevator and places them on the horizontal conveyor during unloading. The horizontal conveyor, the grabbing device, and the storage equipment are installed on the frame, and the grabbing mechanism is installed at a higher position than the horizontal conveyor.

[0005] Furthermore, the grabbing mechanism includes a horizontal slide, a vertical slide, and a suction cup. The movement direction of the horizontal slide is perpendicular to the conveying direction of the horizontal conveyor. The vertical slide is installed at the lower part of the sliding seat of the horizontal slide. The suction cup is a long strip suction cup, and its length is preferably equal to the loading width of the storage box. The suction cup is installed on the sliding seat of the vertical slide. When the grabbing mechanism is loading, the horizontal slide moves to the top of the horizontal conveyor, the vertical slide moves downward, the suction cup grabs the strips and blocks of goods on the horizontal conveyor, and then the vertical slide moves upward. After the horizontal slide moves toward the direction of the elevator to the top of the storage box, the vertical slide moves downward again, and the suction cup puts the goods into the storage box to complete the loading. When the grabbing mechanism is unloading, the horizontal slide moves toward the direction of the elevator to the top of the storage box, the vertical slide moves downward again, the suction cup grabs the goods in the storage box, and then the vertical slide moves upward. After the horizontal slide moves to the top of the horizontal conveyor, the vertical slide moves downward again, and the suction cup puts the goods back onto the horizontal conveyor. Furthermore, a rotating frame is installed on the sliding seat of the vertical slide, and the suction cup is installed on the rotating frame. After the suction cup grabs the goods on the horizontal conveyor, it is rotated 90° and placed in the storage box, or after grabbing the goods in the storage box, it is rotated 90° and placed on the horizontal conveyor. This arrangement can load and unload goods from the side of the storage box, reduce the lifting height of the vertical slide, and the depth of the storage box can be deeper to store more layers of goods.

[0006] Furthermore, the top and one side of the storage box are open, and the block goods enter and exit the storage box from the open side, thereby improving the access speed; further, the storage box can store multiple layers of goods.

[0007] Furthermore, a blocking mechanism is also provided at the rear end of the horizontal conveyor. When the goods blocked by the clamping mechanism reaches a set number, the blocking mechanism will block the subsequent goods so that the number of goods blocked by the clamping mechanism is constant; further, the number of goods blocked by the clamping mechanism is exactly the number of goods in one layer of the storage box, and one layer of the storage box can be sucked up by the suction cup at one time; further, the blocking mechanism includes a cylinder and a baffle installed on the head of the cylinder.

[0008] Furthermore, the elevator includes a door-shaped frame, two guide rails vertically installed on the left and right sides of the door-shaped frame, each of the two guide rails is equipped with a bracket that slides up and down along the guide rail, and the two brackets are synchronously lifted by a chain lifting mechanism, and the two brackets are used to lift the storage box; further, the chain lifting mechanism includes two left and right lifting chains, the left lifting chain is vertically wound around the left driving sprocket and the left driven sprocket, and the right lifting chain is vertically wound around the right driving sprocket and the right driven sprocket, and the left and right driving sprockets are driven by the same rotating shaft. The rotating shaft is driven by a reducer, the left lifting chain is connected to the bracket installed on the left guide rail and pulls the bracket to move up and down, and the right lifting chain is connected to the bracket installed on the right guide rail and pulls the bracket to move up and down; further, a pneumatic push plate is provided on the bracket, and the pneumatic push plates on the two brackets can press and clamp the storage boxes on the two brackets in reverse movement to ensure the safety of the lifting and conveying process; further, the pneumatic push plate is L-shaped, and a baffle is provided at the front end of the elevator to prevent the storage boxes on the elevator from tipping forwards and backwards.

[0009] Furthermore, wheel blocking frames are installed on both sides of the upper conveyor and the lower conveyor to achieve smooth transportation of the storage boxes.

[0010] Furthermore, the upper conveyor and the lower conveyor are both two parallel conveyor belts; further, the upper transport mechanism and the lower transport mechanism both include a horizontal moving frame and a lifting platform installed on the horizontal moving frame, the upper transport mechanism is located between the two parallel conveyor belts of the upper conveyor, and the lower transport mechanism is located between the two parallel conveyor belts of the lower conveyor; the storage box handover method is: after the lifting platform of the upper transport mechanism lifts the storage box on the upper conveyor, the horizontal moving frame moves to the elevator position, the lifting platform descends to place the storage box on the elevator, or after the lifting platform lifts the storage box on the elevator, the horizontal moving frame moves above the upper conveyor, the lifting platform descends to place the storage box on the upper conveyor; similarly, after the lifting platform of the lower transport mechanism lifts the storage box on the lower conveyor, the horizontal moving frame moves to the elevator position, the lifting platform descends to place the storage box on the elevator, or after the lifting platform lifts the storage box on the elevator, the horizontal moving frame moves to above the lower conveyor, the lifting platform descends to place the storage box on the lower conveyor.

[0011] The present invention works as follows: a plurality of empty storage boxes are arranged on the lower conveyor, the lower transport mechanism transfers the storage box to the elevator, and the elevator lifts the storage box to the loading position height. When the downstream equipment of the production line fails and the cargo handling capacity is insufficient, the clamping mechanism starts to clamp the cargo on the horizontal conveyor to block the cargo on the horizontal conveyor. When the blocked cargo reaches a certain quantity, the grabbing device grabs the blocked cargo and loads it into the storage box. After loading one layer, the elevator drops one layer in height, and the boxes are loaded one layer after another. After the storage box is full of cargo, the elevator lifts the storage box to the position of the upper transport mechanism, and the upper transport mechanism transports the storage box to the upper conveyor. In this way, the cargo is loaded one box after another and stored on the upper conveyor. When the downstream equipment of the production line works normally and the upstream equipment suspends the supply of cargo, the stored cargo is put back on the horizontal conveyor. If the storage box on the elevator is not yet full, the grabbing device first takes the cargo in the storage box and places it on the horizontal conveyor. The lifting machine transports the empty storage box to the position of the lower-level handling mechanism, the lower-level handling mechanism transports the empty storage box to the lower-level conveyor, the upper-level handling mechanism transports the storage box filled with goods on the upper-level conveyor to the lifting machine, the lifting machine transports the storage box filled with goods to the height of the unloading position of the goods, the grabbing device grabs the goods in the storage box and puts them on the horizontal conveyor to enter the production process. After the grabbing device takes away a layer of goods, the lifting machine rises one layer in height, takes the goods from the storage box layer by layer, and after taking out a storage box, the storage box is lowered to the position of the lower-level handling mechanism, and the lower-level handling mechanism transports the storage box to the lower-level conveyor, and unloads the goods one by one in this way and stores the empty storage box on the lower-level conveyor, so as to realize the caching of strip and block goods on the production line, solve the backlog caused by downstream equipment failure on the production line, and avoid shutdown of the entire production line; when the downstream equipment is normal and the upstream equipment is temporarily suspended from supplying goods, the stored goods return to the production line to improve production efficiency. In the present invention, empty storage boxes are also arranged on the upper conveyor, and the storage boxes are stored on the lower conveyor after being loaded.

[0012] The present invention discloses an online loading and unloading system for strip and block cargo, comprising a horizontal conveyor, a gripping device, and a storage device. The storage device comprises a storage box and an elevator for transporting the storage box, an upper conveyor, and a lower conveyor. The storage box is exchanged between the elevator and the upper conveyor and the lower conveyor. One of the upper and lower conveyors is used to place empty storage boxes. The horizontal conveyor is connected to the production line. A clamping mechanism is provided at the front end of the horizontal conveyor. When the downstream equipment needs to suspend the supply of goods, the clamping mechanism blocks the goods in transit on the horizontal conveyor. The gripping device grabs the goods on the horizontal conveyor and loads them into the storage box on the elevator. After the storage box is full, it is stored on the upper or lower conveyor. When the downstream equipment returns to normal, the gripping device grabs the goods in the storage box on the elevator and places them on the horizontal conveyor, which effectively solves the backlog caused by the failure of the downstream equipment on the production line and avoids the shutdown of the entire production line.
