Description

Technical Field

[0001] This utility model relates to the field of multi-layer material storage, and more particularly to a multi-layer material storage for laser cutting machines. Background Technology

[0002] With the continuous upgrading and transformation of the manufacturing industry, laser cutting technology has been widely used in many fields due to its significant advantages such as high precision, high speed, good cut quality, and non-contact processing. The multi-layer material storage of laser cutting machines is a raw material storage and supply system designed to support laser cutting machines. It plays a key role in modern manufacturing. From a structural design perspective, it usually adopts a multi-layer three-dimensional architecture, making full use of vertical space and effectively improving storage density. Compared with traditional single-layer material storage, it greatly saves floor space.

[0003] However, traditionally, forklifts are used to place sheet metal on the shelves of the material storage unit. Since the forklifts cannot be accurately positioned in the center by manual judgment, this can lead to misalignment and tilting. The weight of the sheet metal makes adjustment difficult, which in turn causes the automated material handling equipment to become unstable when picking up the sheet metal later, increasing the risk of the sheet metal falling and being damaged, and potentially even causing equipment malfunction. Therefore, a multi-layer material storage unit for laser cutting machines is proposed to solve these problems. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a multi-layer material magazine for laser cutting machines, which aims to improve the problem in the prior art that "when the sheet is placed at an angle, it is inconvenient to adjust the sheet on the shelf, which leads to it falling and being damaged during subsequent gripping".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-layer material storage unit for a laser cutting machine, comprising a storage rack, a lifting platform at the front of the storage rack, a shelf at the top of the lifting platform, a positioning mechanism at the top of the shelf, the positioning mechanism comprising left and right positioning components, front and rear positioning components, and a transmission component, the left and right positioning components comprising a hydraulic rod, the hydraulic rod being fixedly installed on the rear inner side of the shelf, a push plate being fixedly connected to the front surface of the output end of the hydraulic rod, connecting rods being hinged to both the left and right sides of the push plate, guide rods being hinged to the outer side of the other end of the two sets of connecting rods away from the push plate, and side rods being fixedly connected to the top of the two sets of guide rods.

[0006] As a further description of the above technical solution:

[0007] The front and rear positioning components include a guide rack, which is fixedly connected to the bottom end of the push plate and has a toothed groove on the left side. The top of the layer plate is fixedly connected to a fixing plate on the inner side in front of the hydraulic rod.

[0008] As a further description of the above technical solution:

[0009] Both sets of side rods are slidably connected to the top of the shelf, both sets of guide rods and connecting rods are slidably connected to the inner wall of the shelf, and the output end of the hydraulic rod and the push plate are slidably connected to the inner wall of the shelf.

[0010] As a further description of the above technical solution:

[0011] The bottom end of the fixed plate is rotatably connected to a support rod, and the bottom end of the support rod is fixedly connected to a gear.

[0012] As a further description of the above technical solution:

[0013] Gear 2 is fixedly connected to the bottom end of gear 1, and gear 1 meshes with the guide rack on the right side.

[0014] As a further description of the above technical solution:

[0015] The right side of the second gear is engaged with an L-shaped rack, which is configured in an L shape.

[0016] As a further description of the above technical solution:

[0017] The left side of the second gear is engaged with an L-shaped rack, which is configured in an L shape.

[0018] As a further description of the above technical solution:

[0019] The outer protruding tops of both L-shaped racks 2 and 1 are fixedly connected to push rods, and both sets of push rods are slidably connected to the top of the shelf.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the output end of the hydraulic rod drives the push plate to move forward, the push plate drives the connecting rods on both sides to move, and pulls the corresponding guide rods to move inward at the same time. The two sets of guide rods drive the two sets of side rods to move inward at the same time, pushing the left and right sides of the plate on the shelf, thereby pushing and adjusting the plate to be positioned in the center, which facilitates the subsequent automatic material picking and the stability and accuracy of material picking.

[0022] 2. In this utility model, a guide rack is fixed at the bottom of the push plate and engages with gear one and gear two. The guide rack meshes with gear one to make it rotate, which in turn drives gear two to rotate. Gear two meshes with both L-shaped rack one and L-shaped rack two, causing L-shaped rack one and L-shaped rack two to move synchronously toward the center. This drives the push rod at the top to push the front and rear surfaces of the plate, further positioning the plate at the center, which facilitates subsequent automatic material handling and further improves accuracy and material handling stability.

[0030] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a multi-layer material storage unit for a laser cutting machine, comprising a storage frame 1, which is the main body of the multi-layer material storage unit. A lifting platform 2 is installed at the front of the storage frame 1, used to move shelves 3 from or into the storage frame 1. A shelf 3 for placing materials is installed at the top of the lifting platform 2. A positioning mechanism is installed at the top of the shelf 3, comprising left and right positioning components and front and rear positioning components. The left and right positioning components include a hydraulic rod 31 that moves its output end. The hydraulic rod 31 is fixedly installed on the inner rear side of the shelf 3. A push plate 35 that moves connecting rods 34 on both sides is fixedly connected to the front surface of the output end of the hydraulic rod 31. Both sides of the push plate 35 are hinged with outward pushing... Alternatively, the connecting rod 34 can be moved by pulling the guide rod 33. The outer side of the other end of the two sets of connecting rods 34 away from the push plate 35 is hinged with a guide rod 33 that drives the side rod 32 to move. The top of the two sets of guide rods 33 is fixedly connected to the side rod 32. The two sets of side rods 32 can align the left and right sides of the plate and position it at the center when they move inward at the same time. The two sets of side rods 32 are slidably connected to the top of the shelf 3. The two sets of guide rods 33 and connecting rods 34 are slidably connected to the inner wall of the shelf 3. The inner wall of the shelf 3 is provided with a groove to provide movement for the guide rod 33, connecting rod 34 and push plate 35. The output end of the hydraulic rod 31 passes through the shelf 3 and drives the push plate 35 to move. The output end of the hydraulic rod 31 and the push plate 35 are slidably connected to the inner wall of the shelf 3.

[0032] Reference Figure 2 , Figure 4 and Figure 5 The front and rear positioning components include a guide rack 45, which is fixedly connected to the bottom end of the push plate 35. The top of the layer plate 3 is fixedly connected to the inner side in front of the hydraulic rod 31, which is used to support the support rod 43. The bottom end of the fixed plate 47 is rotatably connected to the support rod 43 that supports the first gear 41 and the second gear 42. The bottom end of the support rod 43 is fixedly connected to the first gear 41 that meshes with the guide rack 45 and is driven to rotate by the guide rack 45. The bottom end of the first gear 41 is fixedly connected to the second gear 42 that is driven to rotate by the first gear 41. The first gear 41 meshes with the right guide rack 45.

[0033] Reference Figure 3 , Figure 4 and Figure 5The right side of gear 2 42 is engaged with L-shaped rack 1 44, which is L-shaped. The left side of gear 2 42 is engaged with L-shaped rack 2 46, which is L-shaped. The shelf 3 has grooves for the sliding of L-shaped rack 1 44 and L-shaped rack 2 46. Since both L-shaped rack 2 46 and L-shaped rack 1 44 are L-shaped, they can slide at the bottom of the shelf 3 and can be connected to the push rod 4 corresponding to the top of the shelf 3. The top of the outer protrusion of L-shaped rack 2 46 and L-shaped rack 1 44 are fixedly connected to the push rod 4 that pushes the front and rear surfaces of the plate to be accurately positioned at the center. Both sets of push rods 4 are slidably connected to the top of the shelf 3.

[0034] Working principle: In use, after the board is placed on shelf 3 by a forklift, the hydraulic rod 31 is activated. The output end of the hydraulic rod 31 extends forward, driving the push plate 35 to slide forward in the groove on the inner wall of shelf 3. When the push plate 35 moves, the connecting rods 34 hinged on its left and right sides move accordingly. Since the other end of the connecting rod 34 is hinged to the guide rod 33, and both the guide rod 33 and the connecting rod 34 slide on the inner wall of shelf 3, under the drive of the push plate 35, the two sets of connecting rods 34 pull the corresponding guide rods 33 to move inward at the same time. The top of the guide rod 33 is fixedly connected to the side rod 32, and the side rod 32 slides on the top of shelf 3. Therefore, the two sets of guide rods 33 will drive the two sets of side rods 32 to move inward at the same time, thereby pushing the left and right sides of the board on shelf 3, so that the board is adjusted and positioned in the center in the left and right direction, providing a stable foundation for subsequent automatic material picking and ensuring the accuracy of material picking in the left and right direction.

[0035] Simultaneously, during the left and right positioning process, the push plate 35 moves forward, and the guide rack 45 fixed to the bottom end of the push plate 35 also moves forward synchronously. The guide rack 45 meshes with gear 1 41. When the guide rack 45 moves, it drives gear 1 41 to rotate around the support rod 43. Because gear 2 42 is fixedly connected to the bottom end of gear 1 41, the rotation of gear 1 41 will drive gear 2 42 to rotate synchronously. The right side of gear 2 42 meshes with L-shaped rack 1 44, and the left side meshes with L-shaped rack 2 46. When gear 2 42 rotates, it will cause L-shaped rack 1 44 and L-shaped rack 2 46 to move synchronously away from the center. The push rod 4, which is fixedly connected to the top of the outer protrusion of L-shaped rack 1 44 and L-shaped rack 2 46, moves away from the center under the drive of the L-shaped rack. The outward movement of the side rods 32 allows them to align left and right at the center. After the side rods 32 are reversed and reset, they can drive the two push rods 4 to move towards the center simultaneously, pushing the front and rear surfaces of the plate and further positioning the plate in the center in the front-rear direction. By moving the two side rods 32 and the two push rods 4 in opposite directions, plates of different sizes can be positioned. When positioning rectangular plates, the left and right sides can be positioned first, followed by the front and rear, improving the positioning effect and flexibility. Through the coordinated action of the left and right positioning components and the front and rear positioning components, the plate can be accurately positioned at the center of the shelf 3, facilitating the stable and accurate gripping of the plate by the subsequent automated material handling equipment, reducing the risk of the plate falling and being damaged, and ensuring the efficient and stable operation of the laser cutting machine.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
