Description

Technical Field

[0001] This utility model relates to a loading and unloading device, specifically a loading and unloading device with a circular arrangement of pallets, belonging to the field of automatic loading and unloading technology. Background Technology

[0002] In China's machine tool manufacturing industry, various automated loading and unloading equipment are constantly being developed and applied to meet the demand for 24-hour unmanned machining. In single-machine applications, a single-machine pallet storage unit is typically used; however, in processing units consisting of two or more machine tools, flexible production lines equipped with three-axis or six-axis robots are often employed to achieve automated loading and unloading of multiple machines. By arranging two machine tools side-by-side, a robot's walking track is set in front of the machine tools along the arrangement direction. The three-axis or six-axis robot moves along the track to complete the loading and unloading of both machine tools.

[0003] An existing patent (publication number: CN221270459U) discloses a circulating loading and unloading device for a machine tool, which includes a ground rail, a platform connected to the top of the ground rail, a partition plate installed on the top of the platform, and a conveying assembly installed on the top of the platform. The conveying assembly includes a fixed shell, a servo motor, a support plate, a mounting groove, a linear guide rail, a material plate, a lead screw, and a connecting block. The machine tool's circulating loading and unloading device moves the required materials laterally to the vicinity of the machine tool via a ground rail and a loading platform. The lead screw and connecting block raise the height of the materials, facilitating loading. Combined with the horizontal forward and backward movement of the linear guide rail, the loading plate can bring the materials closer to the machine tool, further facilitating loading and unloading. Simultaneously, loading and unloading operations can be performed on two adjacent machine tools, avoiding frequent back-and-forth material transport by workers and reducing their workload. However, in practical use, since the longitudinal dimension of a horizontal machining center is usually much larger than its transverse dimension, this layout occupies a significant amount of longitudinal space in the factory. This makes it less suitable for users with limited factory space or compact equipment layouts. When performing parallel movement for loading and unloading operations, additional ground-based tracks must be installed, increasing both equipment investment and installation and maintenance costs. Utility Model Content

[0023] 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.

[0024] Example 1

[0025] like Figures 1 to 5 As shown, a pallet-arranged loading and unloading device includes a device housing 1, horizontal machining centers 2 installed on both sides of the device housing 1, a plurality of shelves 3 installed inside the device housing 1, pallets 4 placed on the upper surface of the shelves 3, a clamping mechanism for clamping the pallets 4 provided at the lower end inside the device housing 1, an adjustment mechanism for adjustment inside the clamping mechanism, and a detection mechanism for detecting workpieces provided on one side of the device housing 1.

[0026] The clamping mechanism includes a fixed plate 5, a fixing bolt 51, a mounting part 52, a fixing frame 53, a stepper motor 54, a drive electric cylinder 55, a mounting frame 56, a clamping electric cylinder 57, a clamping plate 58, and a lead screw 59. The fixed plate 5 is installed at the lower end inside the device housing 1. The fixed plate 5 is equipped with a fixing bolt 51 that is threadedly connected to the device housing 1. The fixing bolt 51 ensures the stability of the fixed plate 5.

[0027] Furthermore, a mounting component 52 is fixed to the upper surface of the fixing plate 5. Two fixing brackets 53 are welded and fixed to the upper surface of the mounting component 52. A stepper motor 54 is fixed to the upper surface of each fixing bracket 53 by screws. A lead screw 59 is fixed to the power output shaft of the stepper motor 54. A drive cylinder 55 is threaded to the outer surface of the lead screw 59. Through the mounting component 52 on the fixing plate 5, the external PLC controller simultaneously sends an electrical signal to the stepper motor 54 on the fixing bracket 53, so that the two stepper motors 54 synchronously drive the lead screw 59 to rotate.

[0028] Furthermore, a mounting bracket 56 is fixed to the telescopic end of the drive cylinder 55. A clamping cylinder 57 is fixed to the upper surface of the mounting bracket 56 by screws. A clamping plate 58 is fixed to the telescopic end of the clamping cylinder 57. When the clamping plate 58 moves to a suitable height, the drive cylinder 55 drives the mounting bracket 56 to move horizontally. The clamping cylinder 57 drives the clamping plates 58 to move closer to each other, thereby clamping the tray 4.

[0029] Example 2

[0030] Improvements based on Example 1:

[0031] Furthermore, the adjustment mechanism includes an adjustment motor 6, a drive gear 61, a driven gear 62, and a transmission rod 63. The adjustment motor 6 is fixed inside the mounting part 52 by screws. The drive gear 61 is fixed to the power output shaft of the adjustment motor 6. The adjustment motor 6 can drive the drive gear 61 to mesh with the driven gear 62 and rotate.

[0032] Furthermore, the side wall of the driving gear 61 is meshed with a driven gear 62, and the driven gear 62 has a transmission rod 63 fixedly connected to the fixed frame 53 inside. By rotating the transmission rod 63, the angle of the fixed frame 53 can be adjusted, which facilitates the clamping plate 58 to load and unload the pallet 4. In addition, the device adopts a ring arrangement structure, which can complete the loading and unloading operations of two machine tools on both sides.

[0033] Furthermore, the testing mechanism includes a loading station 7, a fixed seat 71, a placement plate 72, a testing piece 73, and an operating window 74. The loading station 7 is located on one side of the device housing 1. The fixed seat 71 is installed at the lower end of the loading station 7. The processed pallet 4 can be placed on the placement plate 72 through the fixed seat 71 installed on the loading station 7.

[0034] Furthermore, a placement plate 72 is installed on the upper surface of the fixed base 71, and a detection component 73 is installed on the upper surface of the placement plate 72. Two operation windows 74 are opened on the side wall of the loading station 7. The workpiece is inspected through the detection component 73. The operator can call an empty pallet 4 through the operation window 74 and clamp the blank workpiece to be processed on it or call a finished product pallet 4 that has been processed and remove the finished workpiece.

[0035] Working Principle: Before using the pallet-based circular loading and unloading device, first position the outer casing 1 of the device, placing the two horizontal machining centers 2 on either side of the outer casing 1. The two horizontal machining centers 2 are A81NX horizontal machining equipment. The pallet 4 can be placed on the rack 3 installed on the outer casing 1. When loading and unloading workpieces from the pallet 4, the external PLC controller simultaneously sends electrical signals to the stepper motors 54 on the fixed frame 53 via the mounting bracket 52 on the fixed plate 5. This causes the two stepper motors 54 to synchronously drive the lead screw 59 to rotate, which in turn drives the drive cylinder 55 to move vertically, moving the clamping plate 58 to a suitable height. Simultaneously, the drive cylinder 55 drives the mounting frame 56 to move horizontally, and the clamping cylinder 57 moves the clamping plates 58 closer together, thus clamping the pallet 4. The pallet 4 is then transported to one of the horizontal machining centers 2 for processing. The fixing bolts 51 ensure the stability of the fixing plate 5. The adjustable motor 6 drives the drive gear 61 to mesh with the driven gear 62 to rotate, thereby driving the transmission rod 63 to rotate. This allows for adjustment of the angle of the fixing frame 53, facilitating the loading and unloading of the pallet 4 by the clamping plate 58. Furthermore, the device adopts a ring-shaped arrangement structure, which can complete the loading and unloading operations of two machine tools on both sides. Only one three-axis handling mechanism is needed to achieve efficient operation. There is no need to set up a ground walking track, which reduces the equipment composition and installation process and significantly reduces equipment costs. The fixed seat 71 set on the loading station 7 can place the processed pallet 4 onto the placement plate 72. The workpiece is inspected by the detection piece 73. The operator can call the empty pallet 4 through the operation window 74 and clamp the blank workpiece to be processed on it or call the finished pallet 4 that has been processed and remove the finished workpiece.
