Description

Technical Field

[0001] The utility model relates to the technical field of material transportation devices, in particular to a stacking type material loading and unloading machine. Background Art

[0002] Soft ferrite is a functional magnetic material used to make electronic components. Its production process includes pulping, pressing, debinding, sintering and other processes. Among them, sintering is an important link in the production of soft ferrites. The sintering process and sintering equipment directly determine the product performance of soft ferrites. Before sintering, soft ferrite workpieces need to be stacked on the kiln car in the form of stacks. Each stack has about 20-30 layers of support plates (universal parts), and each layer of support plates holds about 3-6 layers of soft ferrite workpieces. At present, the stacking of soft ferrite workpieces generally adopts manual stacking, which has the defects of time-consuming and labor-intensive loading, easy shaking and scattering during loading and unloading and transportation.

[0003] In response to the above problems, patent document CN107954364A discloses an automatic loading and unloading machine for stacking materials, including a frame and a fork for holding materials, which can be lifted and moved horizontally under the drive of a lifting and translation assembly, and is also equipped with a feeding trolley. When the automatic loading and unloading machine is working, the lifting and translation assembly drives the fork to lift and move horizontally, and can lift the materials placed on the base of the feeding trolley and send them to the equipment to be loaded, or lift the materials on the equipment to be unloaded and send them to the feeding trolley, thereby realizing the automatic loading and unloading of materials, which can greatly improve production efficiency, save labor and reduce costs.

[0004] However, in this device, due to the limitation of the force-bearing structure of the supporting fork, the weight of the material transported at one time cannot be too much, otherwise the supporting fork will tilt toward the fork end, thereby deteriorating the structural stability of the device. Utility Model Content

[0008] As a further improvement of the above solution:

[0012] The lower ends of the first supporting rod and the second supporting rod are both provided with supporting protrusions for supporting stacked materials.

[0013] A correction mechanism for correcting the loading and unloading path of the feeding trolley is also provided under the frame. The correction mechanism includes correction tracks symmetrically arranged on both sides of the material support frame and parallel to the translation direction of the material support frame. A plurality of vertically arranged rollers are spaced apart on the correction tracks, and a rubber buffer layer is provided on the outer surface of the rollers.

[0014] The deviation-correcting track is provided with a positioning plate which is arranged perpendicular to the translation direction of the material support frame toward the end of the loading and unloading position.

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Figures 1 to 7 An embodiment of a stacking material loader and a feeding trolley 7 of the utility model is shown, and the stacking material loader and unloader includes a frame 4, a material supporting frame 1 for supporting materials, a translation drive component 2 for driving the material supporting frame 1 to move horizontally on the frame 4, and a lifting drive component 3 for driving the material supporting frame 1 to move up and down on the frame 4, characterized in that: the material supporting frame 1 includes a first supporting rod 11 and a second supporting rod 12 arranged symmetrically, and a first space 14 for accommodating stacking materials 8 is provided between the first supporting rod 11 and the second supporting rod 12; the lifting drive component 3 includes a lifting drive motor 31 and a turbine screw lifting mechanism 32, and the screw 321 of the turbine screw lifting mechanism 32 is fixedly connected to the material supporting frame 1 and is coaxially arranged at the center of the material supporting frame 1. In this structure, the axis of the screw 321 in the turbine screw lifting mechanism 32 coincides with the central axis of the material support frame 1, so as to improve the stability of the lifting mechanism during the lifting process, make the lifting of materials more stable, improve the structural stability of the material support frame 1, and enable the material support frame 1 to support more stacked materials 8 at a time, thereby improving the loading and unloading efficiency of materials.

[0029] In this embodiment, the translation drive assembly 2 includes a translation drive motor 21, an upper fixed frame 22 and a pulley. The upper fixed frame 22, the lifting drive motor 31 and the turbine screw lifting mechanism 32 are all fixedly connected to the upper fixed frame 22. The upper fixed frame 22 is slidably sleeved with the material support frame 1; the upper fixed frame 22 is slidably connected with the frame 4 by sliding, and the pulley includes two sets of driven pulleys 23 and two sets of active pulleys 24 connected to the output shaft of the translation drive motor 21. In this structure, the setting of the upper fixed sleeve, on the one hand, connects the material support frame 1 and the lifting drive assembly 3 with the frame 4 as a whole, and drives the material support frame 1 to perform translational movement along the frame 4, and on the other hand, can guide the lifting movement of the material support frame 1, with a compact structure and good stability.

[0030] In this embodiment, a loading and unloading position 5 for placing a device to be loaded or unloaded is provided at one end below the frame 4 along the translation direction of the material support frame 1, and a trolley inlet and outlet 41 is provided on the frame 4 at the other end of the loading and unloading position 5 relative to the loading and unloading position 5 for a feeding trolley to load or unload the material support frame 1. Specifically, the relative direction of the first supporting rod 11 and the second supporting rod 12 is perpendicular to the translation direction of the material support frame 1. The lower ends of the first supporting rod 11 and the second supporting rod 12 are both provided with a supporting protrusion 13 for supporting the stacked material 8. In this structure, the feeding trolley 7 can enter the interior of the frame 4 from the trolley inlet and outlet 41, and move forward along the translation direction of the material support frame 1 until it runs to the bottom of the material support frame 1, and transports the material to the first space 14, so that the material support frame 1 can support the material on the feeding trolley 7, or unload the material in the first space 14 onto the loading trolley. The material support frame 1 only needs to move up and down during the loading and unloading process, without horizontal displacement, which simplifies the loading and unloading operation steps. It also eliminates the need for the material support frame 1 to move horizontally for loading and unloading, making the overall structure of the stacking material loader more compact.

[0031] In this embodiment, a correction mechanism 6 for correcting the loading and unloading path of the feeding trolley 7 is also provided under the frame 4. The correction mechanism 6 includes correction rails 61 symmetrically arranged on both sides of the material support frame 1 and parallel to the translation direction of the material support frame 1. A plurality of vertically arranged rollers 62 are spaced apart on the correction rails 61, and a rubber buffer layer is provided on the outer surface of the rollers 62.

[0032] In this embodiment, a positioning plate 63 which is arranged perpendicular to the translation direction of the material support frame 1 is arranged at the end of the deviation correction track 61 toward the loading and unloading position 5 .

[0033] A feeding trolley 7 applied to the above-mentioned stacking material loading and unloading machine comprises a base 71 with running wheels 72 and a handrail 73 fixedly connected to the base 71, a deflection correction plate 74 movably arranged on the base 71, which can be slidably contacted and connected with the deflection correction tracks 61 on both sides for deflection correction during loading and unloading; two support bars 75 are arranged at intervals on the deflection correction plate 74, the support bars 75 are arranged parallel to the forward direction of the feeding trolley 7, and the support bars 75 include a support end 751 that can be abutted on the positioning plate 63; a second space 76 for inserting the supporting protrusion 13 is formed between the support bar 75 and the adjacent deflection correction track 61. In this structure, the deflection correction plate 74 is in contact with the base 71, and during the loading and unloading process, the stacking material 8 is located above the support bar 75, so that a second space 76 for inserting the supporting protrusion 13 is formed between the support bar 75 and the deflection correction track 61. When the feeding trolley 7 runs to the bottom of the material support frame 1, the rollers 62 on both sides will slide in contact with the side edges of the correcting plate 74 and gradually adjust the position of the correcting plate 74 to make it parallel to the correcting track 61, ensuring that loading and unloading can proceed normally. The feeding trolley 7 has a simple structure and is easy to operate.
