Description

Technical Field

[0001] The present invention relates to the technical field of strip material processing and transportation, and in particular to an automatic strip material unloading and stacking system and a working method. Background Art

[0002] Strips (mainly reinforced flat steel and surface materials, which are collectively called strips because of their integrated nesting and similar processing technology) are widely used in hull structures. They have the characteristics of complex processing technology, many shapes and types, different lengths, high material volume, and large amount of free edge grinding. At present, the free edge processing of strips is generally achieved by chamfering the long edges with a chamfering machine and chamfering the ends. After chamfering and grinding, the strips need to be manually moved from the chamfering machine transport roller to the pallet one by one, which has low operation efficiency and high labor intensity, and also brings great safety hazards. Summary of the invention

The unloading trolley is used to transfer incoming materials from upstream to an area that can be lifted by the unloading electromagnetic lifting mechanism, the unloading electromagnetic lifting mechanism is used to transfer materials to the transverse movement mechanism, the transverse movement mechanism drives the materials to move transversely, a stop mechanism is arranged on the transverse movement mechanism, the stop mechanism is used to stop a preset amount of strips, and descends after reaching a preset height, so as to transport the stacked strips to the unloading point.

[0006] Furthermore, each area of ​​Zone A and Zone B can complete automatic unloading of 800mm-7400mm strips respectively.

[0007] Furthermore, a spacing area is provided between area A and area B, and based on the length of the spacing area, automatic unloading of materials of 7400mm-15000mm is completed as a whole.

[0008] Furthermore, the transverse movement mechanism includes a motor and a conveyor belt / sprocket chain structure, each transverse movement mechanism includes a conveyor belt / sprocket chain structure, area A and area B each include a motor, and each transverse movement mechanism in each area completes synchronous rotation by connecting a coupling and a rotating shaft through a motor.

The lifting bracket is vertically arranged on the bottom surface, a slide rail is arranged above the lifting bracket, a slidable movable hanger is arranged on the slide rail, and an electromagnetic lifting beam is arranged at the bottom end of the movable hanger. When the electromagnetic lifting beam is powered on, its bottom end is adsorbed to the strip to be transported.

[0011] Furthermore, an electromagnetic lifting beam lifting device is arranged at the bottom end of the movable hanger, and the electromagnetic lifting beam is driven to be lifted and lowered by a power source.

[0012] Furthermore, the material receiving trolley includes a plurality of pushing devices and a trolley body arranged at a preset position of the grinding roller.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0030] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0031] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0032] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0033] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
