Description

Technical Field

[0001] This utility model belongs to the technical field of spandex production, and in particular relates to an automatic palletizing equipment for finished spandex boxes leaving the warehouse. Background Technology

[0002] Palletizing finished spandex boxes is a crucial step in the spandex production process. With the continuous development of automation technology, when finished boxes leave the automated warehouse, workers manually move them from the iron pallets used for outbound pallets to the wooden pallets used for loading. After stacking and storage, the entire pallet is then wrapped with film to create a pallet of spandex products. However, this process still has the following drawbacks in practical use:

[0003] During the palletizing process of spandex products, different pallets of products need to be moved when facing the upper input equipment in different directions. In operation, the palletizing equipment's pallets are not very adaptable to input equipment in different directions, and the arrangement of the palletizing equipment is not flexible enough.

[0004] Secondly, in the overall palletizing process, the pallets are transported by clamping and stacked one by one. This requires a large amount of equipment to complete the palletizing of the finished spandex boxes, which results in high equipment costs and a large space occupation. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic palletizing equipment for outbound shipment of spandex finished product boxes. By setting up an internal support frame, a support frame and a lifting plate, it solves the problems of insufficient flexibility in the arrangement of palletizing equipment and large equipment cost and space occupation in the palletizing of spandex finished products.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an automatic palletizing device for spandex finished product boxes, comprising an inner support, a support frame, and a lifting plate. Support shells are fixed to the two long sides of the top of the inner support, and guide plates are fixed to the sides of the two support shells that are far apart from each other. A support frame is installed on a short vertical surface inside the inner support. Lifting cylinders are installed at the four corners of the bottom of the support frame, and the extension and retraction ends of the lifting cylinders are fixed to the bottom of the support frame. A limit plate is fixed inside the inner support. Lifting plates are symmetrically arranged on the two long sides of the top of the inner support between the limit plate and the support frame, and the lifting plates are located on the top of the inner support outside the support shells. During operation, the inner support supports the support frame and the lifting plate, and in operation, it drives the pallet to move on it. During operation, an electric roller is connected to the support frame. The lifting cylinders drive the support frame to rise and fall, and the lifting plate, in turn, drives the pallet to rise and fall, thus stacking the pallets during the lifting and falling process.

[0008] Furthermore, each of the support shells has an open top, and each support shell has a sprocket symmetrically rotatably connected inside. The two sprockets inside each support shell are engaged with a chain on their circumferences. The two sprockets inside the support shell engage the chain, and the chain moves as the sprockets rotate.

[0009] Furthermore, a drive motor is fixed at a corner on the side of one of the support shells away from the center of the inner bracket. A transmission shaft is fixed at the output end of the drive motor, and the transmission shaft passes through sprockets at the same position in both support shells. The transmission shaft is fixed to the sprockets in the two support shells respectively. When the drive motor is working, it drives the transmission shaft to rotate, and the rotation of the transmission shaft drives the sprockets to rotate.

[0010] Furthermore, the top of the support frame is open, and electric rollers are rotatably connected at equal intervals inside the support frame. The central axis of the electric rollers is perpendicular to the length direction of the support shell. The support frame connects the electric rollers therein, and drives the pallet to move after the pallet moves onto it.

[0011] Furthermore, a movable groove is fixed on one side of the two lifting plates that are far apart from each other. A push cylinder is fixed in the center of the movable groove on the side away from the lifting plate. The telescopic end of the push cylinder passes through one side of the movable groove and a fitting block is fixed to the telescopic end of the push cylinder. The fitting block is movably connected in the movable groove and is movably connected through the lifting plate. When the movable groove on the lifting plate is working, the fitting block is movably connected in it, and the push cylinder pushes the fitting block to move.

[0012] Furthermore, connecting blocks are symmetrically fixed to the lower part of the two lifting plates on the side away from each other. A hydraulic lift is provided below each connecting block. The telescopic end of the hydraulic lift is fixed to the bottom of each connecting block. When the lifting plate is in operation, the connecting block is connected to the telescopic end of the hydraulic lift, and the hydraulic lift drives the lifting plate to rise and fall.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of inflexible palletizing equipment layout in spandex finished product palletizing by setting up an inner support and a support frame. It determines where the pallets to be stacked should be transported to the top of the inner support. If the pallets are transported from one end of the inner support to the top, the drive motor is directly started, driving the transmission shaft to rotate. As the transmission shaft rotates, it drives the sprockets in the two support shells to rotate. The rotation of the sprockets drives the chain, moving the pallets from the upper conveyor to the top of the two support shells. Then, with the movement of the chain, the pallets move between the two lifting plates above the inner support for stacking. The pallet being stacked moves from one side of the inner support to the top of the support frame. During this process, the four lifting cylinders at the bottom of the support frame are activated simultaneously, driving the support frame to rise until the height of the electric roller at the top of the support frame is consistent with the height of the upper-level conveyor. Then, the electric roller is activated, and its rotation direction is consistent with the direction in which the upper-level conveyor transports the pallet. The upper-level pallet is then transported to the top of the support frame and moved by the rotation of the electric roller to a position between the two support shells from a top-down perspective. This allows the palletizing equipment to be suitable for pallet input from multiple directions in the stacking of spandex finished products, making operation more convenient.

[0015] This invention solves the problems of high equipment cost and large space occupation in the stacking of spandex finished products by setting up an internal support and lifting plate. When the pallet moves between the two lifting plates and is positioned by the limiting plate, the pushing cylinder on the outside of the lifting plate is activated. The pushing cylinder pushes the interlocking block to move until the interlocking block is pushed between the pallet's legs. At the same time, four hydraulic lifting machines are activated, and the four hydraulic lifting machines synchronously drive the connecting block to rise, which in turn drives the interlocking block to rise. After the lifting plate rises, it drives the pallet to rise, and the finished spandex on the pallet is also driven to rise. Subsequently, the subsequent pallets and the finished spandex on them are also driven to rise. After the finished spandex pieces move to the position limited by the limiting plate, four push cylinders are activated to simultaneously drive two lifting plates to descend. The clamped pallet is then supported on top of the limiting plate structure. Subsequently, four push cylinders are activated to move the interlocking block out from between the pallet legs. At this point, the two pallets of finished spandex pieces are stacked on top of each other. Then, four push cylinders are restarted to simultaneously drive the two lifting plates to descend to the top of the inner support. After the two lifting plates move to the top of the inner support, the above work is repeated. This makes the equipment cost and space occupation less in the stacking of finished spandex pieces, and the operation is more convenient. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0026] Please see Figure 1-36. This utility model is an automatic palletizing device for spandex finished product boxes, including an inner support 1, a support frame 2, and a lifting plate 3. Support shells 101 are fixed to the two long sides of the top of the inner support 1. During operation, the inner support 1 movably connects the support frame 2 and supports the lifting plate 3 on it. The support shells 101 movably connect the chain 106 and the sprocket 103. Guide plates 102 are fixed to the sides of the two support shells 101 that are far apart from each other. During operation, the guide plates 102 guide the pallet onto the chain 106 at the top of the support shells 101. The support frame 2 is located on a short vertical surface inside the inner support 1, and the support frame 2 holds the electric roller 201. The support frame 2 is rotatably connected to the support frame 2. Each of the four corners at the bottom of the support frame 2 is equipped with a lifting cylinder 202. The extension and retraction ends of the lifting cylinder 202 are fixed to the bottom of the support frame 2. The bottom support of the lifting cylinder 202 is set on the ground. When the lifting cylinder 202 is working, it drives the support frame 2 to rise and fall. When the support frame 2 rises and falls, it drives the electric roller 201 to rise and fall. The inner bracket 1 is fixed with a limit plate 4. The limit plate 4 limits the movement of the pallet that contacts it. The two long sides of the top of the inner bracket 1 between the limit plate 4 and the support frame 2 are symmetrically provided with lifting plates 3. When the lifting plates 3 rise and fall, they drive the pallet to rise and fall. The lifting plates 3 are set on the top of the inner bracket 1 outside the support shell 101.

[0027] Specifically, each support shell 101 has an open top, and each support shell 101 has a sprocket 103 symmetrically rotatably connected inside. The two sprockets 103 inside each support shell 101 are engaged with a chain 106 on their periphery. When the support shell 101 is working, the sprockets 103 therein movably connect the chain 106 therein.

[0028] Furthermore, a drive motor 104 is fixed at a corner of one of the support shells 101 away from the center of the inner bracket 1. A transmission shaft 105 is fixed at the output end of the drive motor 104. The transmission shaft 105 passes through the sprockets 103 at the same position in the two support shells 101. The transmission shaft 105 is fixed to the sprockets 103 in the two support shells 101 respectively. The drive motor 104 drives the sprockets 103 to rotate, which drives the chain 106 to move, so that the tray that moves onto the support shell 101 is driven to move toward the limiting plate 4.

[0029] Furthermore, the top of the support frame 2 is open, and electric rollers 201 are rotatably connected at equal intervals inside the support frame 2. The central axis of the electric rollers 201 is perpendicular to the length direction of the support shell 101. When the support frame 2 is working, the opening on it fixes the electric rollers 201, and when the electric rollers 201 rotate, they drive the pallet moving on it to move.

[0030] The operation process of this embodiment is as follows: During operation, firstly, determine where the pallets to be stacked are transported to the top of the inner support 1. If they are transported from one end of the inner support 1 to the top of the inner support 1, then directly start the drive motor 104 to drive the transmission shaft 105 to rotate. When the transmission shaft 105 rotates, it drives the sprockets 103 in the two support shells 101 to rotate. As the sprockets 103 rotate, they drive the chain 106 to move, driving the pallets to move from the upper conveying equipment to the top of the two support shells 101. Then, with the movement of the chain 106, the pallets move between the two lifting plates 3 above the inner support 1 for stacking. When the pallets to be stacked move from one side of the inner support 1 to the support frame 2... At the top, during this process, the four lifting cylinders 202 at the bottom of the support frame 2 are simultaneously activated, driving the support frame 2 to rise until the height of the electric roller 201 at the top of the support frame 2 is consistent with the height of the upper conveying equipment. Then, the electric roller 201 is activated, and the rotation direction is consistent with the direction of the transport pallet of the upper conveying equipment. The upper pallet is transported to the top of the support frame 2 and moved by the rotation of the electric roller 201 to be positioned between the two support shells 101 from a top-down perspective. Then, the four lifting cylinders 202 are activated, driving the support frame 2 to descend onto the chain 106 supported on the two support shells 101. The moving chain 106 drives the support frame 2 to contact the limit plate 4. Specific Implementation Example 2

[0031] Please see Figure 1-6 Based on the first specific embodiment, a movable groove 301 is fixed on one side of the two lifting plates 3 that are far apart from each other. A push cylinder 303 is fixed in the center of the movable groove 301 on the side away from the lifting plate 3. The telescopic end of the push cylinder 303 passes through one side of the movable groove 301 and a fitting block 302 is fixed to the telescopic end of the push cylinder 303. The fitting block 302 is movably connected in the movable groove 301 and is movably connected through the lifting plate 3. When the lifting plate 3 is working, the movable groove 301 on it is movably connected to the fitting block 302. After the push cylinder 303 pushes the fitting block 302, it causes the fitting block 302 to move into the gap between the pallet legs, so that the pallet can be supported and set up.

[0032] Specifically, connecting blocks 304 are symmetrically fixed to the lower part of the two lifting plates 3 on the side away from each other. A hydraulic lift 305 is provided below each connecting block 304. The telescopic end of the hydraulic lift 305 is fixed to the bottom of each connecting block 304. The bottom of the hydraulic lift 305 is supported on the ground. When the connecting block 304 is working, the hydraulic lift 305 at the bottom of the connecting block 304 drives the connecting block 304 to rise and fall. The hydraulic lifts 305 at the bottom of all connecting blocks 304 drive the connecting blocks 304 to rise and fall synchronously.

[0033] The operation process of this embodiment is as follows: During operation, when the pallet moves between the two lifting plates 3 and is positioned by the limiting plate 4, the pushing cylinder 303 on the outside of the lifting plate 3 is activated. The pushing cylinder 303 pushes the interlocking block 302 to move until the interlocking block 302 is pushed between the legs of the pallet. Then, four hydraulic lifting machines 305 are activated simultaneously. The four hydraulic lifting machines 305 synchronously drive the connecting block 304 to rise, which in turn drives the lifting plate 3 to rise. After the lifting plate 3 rises, it drives the interlocking block 302 to rise, causing the pallet to rise. The finished spandex on the pallet is also lifted. Then, after the subsequent pallets and the finished spandex on them move to the position limited by the limiting plate 4, the four hydraulic lifting machines 305 are activated. One push cylinder 303 synchronously drives two lifting plates 3 to descend, clamping the pallet and supporting it on the top of the limiting plate 4 structure. Then, four push cylinders 303 are activated to move the interlocking block 302 out from between the pallet legs. At this time, the two pallets of stacked finished spandex are stacked on top of each other. Then, four push cylinders 303 are restarted to synchronously drive the two lifting plates 3 to descend to the top of the inner support 1. After the two lifting plates 3 move to the top of the inner support 1, the above work is repeated until eight pallets are stacked. Then, the drive motor 104 is started to reverse, the chain 106 reverses, and the pallets are moved on the two support shells 101 to the subsequent packaging and conveying equipment.
