Abstract
Description
Technical Field
[0001] The utility model relates to a work material frame, and particularly to a work material frame for processing waste materials. Background Art
[0002] After processing workpiece raw materials at the production site (such as a processing workshop), there are usually remaining processing waste materials, which need to be stacked and temporarily stored and then transported subsequently.
[0003] Taking the processing of aluminum coils as an example, during processing such as cold rolling, straightening, cleaning, and slitting, due to reasons such as starting and ending, the quality of the head and tail of the aluminum coil is usually poor (such as sticking aluminum, scratching, thickness difference, etc.). When the aluminum coil is processed on the machine table, about 5 - 10 turns are cut off at the head, and 5 - 10 turns at the tail are reserved and scrapped. More than 100 small waste coils are generated every day. Such small coils will be temporarily placed at the production site and then transported to the waste material warehouse.
[0004] The existing processing method is to directly stack the small waste coils in the idle floor area of the production site, and then use a transfer tool or a transportation tool (such as a forklift) to transport them to the waste material warehouse. However, due to the large number of small coils generated daily, if these small coils are placed in a single layer (i.e., the small coils are placed adjacent to each other one by one) on the floor, the floor area occupied is large and a large space is occupied. If these small coils are arranged vertically on top of each other in multiple layers (such as two layers or more), due to the large weight of the small coils themselves, the smooth surface of the small coils, and the small friction coefficient of the surfaces where the small coils contact each other, the stacking of the small coils is not stable, and the position of the upper small coils is likely to change. For example, the upper small coils are likely to move left and right, and even slide from the upper layer to the lower layer or the ground, posing a safety hazard and easily causing safety accidents.
[0005] In addition, whether placed in a single layer or stacked in multiple layers, the small coils wound and packed are likely to unwind and impact nearby workers or other items, causing injury to people and damage to items. These unwound small coils need to be rewound, packed, stacked, and transported, which is time-consuming and laborious.
[0006] In addition, when using a forklift to transport these small coils, only 1 to 2 coils can be transported at a time, and it takes a long time and is inefficient to transport all the small coils; moreover, during the transportation process, there is a risk that the small coils will unwind or even fall off the forklift.

[0031] Now referring to the accompanying drawings, the detailed embodiments of the present utility model will be described in detail. What is described herein is only the preferred embodiments of the present utility model. Those skilled in the art can think of other ways to implement the present utility model based on the preferred embodiments, and such other ways also fall within the scope of the present utility model.
[0032] Figure 1 A work material frame 10 is shown. This work material frame is used to hold various work materials, and in particular, is used to hold processing waste. Here, an aluminum coil is taken as an example to describe the work material frame, but it is not limited thereto. The work material frame can also be used to hold other various types, shapes, and materials of work materials.
[0033] See Figure 1 , which shows that the overall work material frame is a cubic basket structure, but it is not limited thereto. The work material frame can be other structures and configurations according to needs; for example, the work material frame can be cylindrical, prismatic, pyramidal, and other regular and irregular configurations. Figure 1A coordinate system is marked, showing the front - rear direction, the up - down direction, and the left - right direction. This coordinate system is only for the convenience of description and is not restrictive. Only as an example, in the present disclosure, the left - right direction is taken as the transverse direction, the front - rear direction is taken as the longitudinal direction, and the up - down direction is taken as the vertical direction; the present disclosure can also take the front - rear direction as the transverse direction and the left - right direction as the longitudinal direction.
[0034] Refer to Figure 1 and Figure 2 , the work - material frame 10 includes a chassis 11, two opposite side frames 12, and a rear frame 13. Among them, the chassis 11 is horizontally oriented and used to support the work - material. The two side frames 12 extend vertically upward from both sides of the chassis 11 and are opposite to each other. The rear frame 13 extends vertically upward from the rear of the chassis 11 and is connected between the two side frames 12, so that the chassis 11, the two opposite side frames 12, and the rear frame 13 enclose an accommodation space for receiving the work - material. Among them, the chassis 11 includes at least two chassis transverse bars 111 and at least three chassis longitudinal bars 112, and the chassis transverse bars 111 and the chassis longitudinal bars 112 are cross - connected to each other. Each side frame includes at least two side - frame vertical bars 121 and at least one side - frame longitudinal bar 122. Among them, each side - frame vertical bar 121 is connected to each chassis transverse bar 111 in alignment. The rear frame 13 includes at least one rear - frame transverse bar 131.
[0035] The chassis 11, the two opposite side frames 12, and the rear frame 13 can be a multi - bar grille or fence structure. Taking the chassis 11 as an example, as Figure 1 shown, the chassis 11 includes three chassis transverse bars 111 and four chassis longitudinal bars 112. The chassis transverse bars and the chassis longitudinal bars are preferably perpendicularly connected to each other to form a grille or fence - like frame structure; in addition, Figure 1 also shows a reinforcing cross - bar between two middle chassis longitudinal bars 112 for increasing the structural strength of the chassis. It should be noted that the number of the chassis transverse bars and the chassis longitudinal bars is only an example and is not restrictive. Those skilled in the art can flexibly select the number of the chassis transverse bars and the chassis longitudinal bars according to actual applications. The chassis transverse bars and the chassis longitudinal bars can be fixedly connected together, for example, by welding, riveting, threaded connection, snap connection, mortise - and - tenon connection, and other mechanical connection methods. The chassis transverse bars and the chassis longitudinal bars are rod - shaped members, which should be understood in a broad sense. The rod can be a solid or hollow structure. When a solid structure is adopted, the cross - sectional shape of the rod can be circular, rectangular, square, or other regular or irregular polygons; correspondingly, when a hollow structure is adopted, the rod can be called a tube, such as a cylindrical tube, a rectangular tube, a square tube, or other regular or irregular polygon tubes. The rod preferably adopts a solid structure to reduce its own weight and the energy consumed during subsequent transportation by a transportation tool (taking a forklift as an example).
[0036] The rod can be made of various materials as long as the requirements such as strength and stiffness are met, for example, metal materials (such as iron, aluminum, etc.), alloy materials, polymer materials, composite materials, etc. There are also no restrictions on the dimensions of the rod itself (such as length, width, thickness or diameter), and it can be flexibly selected according to actual applications as long as the requirements such as strength and stiffness are met.
[0037] Similarly, Figure 1 and Figure 2 It is shown that each side frame 12 includes three side frame vertical rods 121 and three side frame longitudinal rods 122 arranged from top to bottom. At the connection between the side frame 12 and the underframe 11, there is no side frame longitudinal rod 122, but the three side frame vertical rods 121 directly extend upward from a corresponding underframe longitudinal rod 112 (i.e., the leftmost underframe longitudinal rod 112). Similarly, the rear frame 13 includes three rear frame cross rods 131 and two rear frame vertical rods 132. At the connection between the rear frame 13 and the underframe 11, there is no rear frame cross rod 131, but the two rear frame vertical rods 132 directly extend upward from a corresponding underframe cross rod 111 (i.e., the rearmost underframe cross rod 111); at the connection between the rear frame 13 and the side frame 12, there is no rear frame vertical rod 132, but the three rear frame cross rods 131 directly extend between the corresponding side frame vertical rods 121 of the two side frames (i.e., the two rearmost side frame vertical rods 121). In other words, each side frame 12 shares an underframe longitudinal rod 112 with the underframe 11 respectively, the rear frame 13 shares an underframe cross rod 111 with the underframe 11, and the rear frame 13 shares a side frame vertical rod 121 with each side frame 12 respectively.
[0038] In the drawings, it is shown that the side frame vertical rods 121 and the rear frame vertical rods 132 are arranged in the up-down direction, the underframe longitudinal rods 112 and the side frame longitudinal rods 122 are arranged in the front-rear direction, and the underframe cross rods 111 and the rear frame cross rods 131 are arranged in the left-right direction. Among them, the side frame longitudinal rod 122 is aligned with the rear frame cross rod 131, the side frame vertical rod 121 is aligned with the underframe cross rod 111, and the rear frame vertical rod 132 is aligned with the underframe longitudinal rod 112. Alignment means that the corresponding rods are connected one-to-one, which is only an example and not restrictive. For example, the side frame longitudinal rod 122 may not be aligned with the rear frame cross rod 131, and the quantities may also be different, so that they are arranged in a staggered and crossed manner. The side frame vertical rod 121 may not be aligned with the underframe cross rod 111, and the quantities may also be different, so that they are arranged in a staggered and crossed manner. The rear frame vertical rod 132 may not be aligned with the underframe longitudinal rod 112, and the quantities may also be different, so that they are arranged in a staggered and crossed manner. For example, the middle side frame vertical rod 121 of the side frame 12 can be omitted, or the middle underframe cross rod 111 of the underframe 11 can be omitted.
[0039] As described below and Figure 2 stated, forFigure 1 The number of rods of the chassis shown, each space formed between two adjacent longitudinal chassis rods 112 of the chassis 11 can be used to accommodate an aluminum coil. Among them, the aluminum coil is cylindrical, the transverse dimension (i.e., diameter) of the aluminum coil corresponds to the first transverse spacing D1 between two adjacent longitudinal chassis rods 112, and the longitudinal dimension (i.e., length) of the aluminum coil corresponds to the longitudinal dimension L of the chassis 11 (i.e., the longitudinal dimension L of the longitudinal chassis rod 112 itself, i.e., the length L). Since the chassis includes four longitudinal chassis rods 112, the chassis 11 can accommodate three aluminum coils. The middle transverse chassis rod 111 of the chassis 11 is used to increase the structural strength and can be omitted.
[0040] Similarly, the second vertical spacing D2 between the lowermost side frame longitudinal rod 122 of the side frame 12 and the longitudinal chassis rod 112 of the chassis 11, and the second vertical spacing D2 between two adjacent side frame longitudinal rods 122 of the side frame 12 correspond to the vertical dimension (i.e., diameter) of the aluminum coil; the third vertical spacing D3 between the lowermost rear frame transverse rod 131 of the rear frame 13 and the transverse chassis rod 111 of the chassis 11, and the third vertical spacing D3 between two adjacent rear frame transverse rods 131 of the rear frame 13 correspond to the vertical dimension (i.e., diameter) of the aluminum coil; in the present disclosure, the second vertical spacing between the lowermost side frame longitudinal rod 122 of the side frame 12 and the longitudinal chassis rod 112 of the chassis 11 is set to be equal to the second vertical spacing between two adjacent side frame longitudinal rods 122 of the side frame 12, and the third vertical spacing between the lowermost rear frame transverse rod 131 of the rear frame 13 and the transverse chassis rod 111 of the chassis 11 is set to be equal to the third vertical spacing between two adjacent rear frame transverse rods 131 of the rear frame 13. This is only an example, and their size relationship can be flexibly set according to actual engineering applications. Therefore, based on Figure 1 the structure shown, three layers of aluminum coils can be placed, and the number, arrangement, and dimensions of the corresponding rods of the chassis 11, side frame 12, and rear frame 13 can be adjusted according to actual needs (e.g., the size of the aluminum coil) to adjust the number of aluminum coils accommodated by the frame 10.
[0041] The above descriptions about the number, connection method, structure, material, and dimensions of the rods of the chassis 11 also apply to the side frame 12 and the rear frame 13, and will not be elaborated here.
[0042] The material and work frame 10 can be a modular component, that is, similar to ready-to-assemble furniture. The chassis 11, side frame 12, and rear frame 13 are manufactured separately and then assembled together during use. The assembly process is simple and time-consuming.
[0043] In order to prevent the work materials from falling through the space between the rods when they are contained within the frame 10, the distance or gap between the rods should be restricted. Specifically, the corresponding spacing between the rods should be set to be less than the corresponding dimension of the work materials, that is, the first lateral spacing D1 is less than the lateral dimension of the work materials, the second vertical spacing D2 is less than the vertical dimension of the work materials, the third vertical spacing D3 is less than the vertical dimension of the work materials, and the longitudinal dimension L of the underframe longitudinal rod 112 itself is less than the longitudinal dimension of the work materials.
[0044] Taking aluminum coil waste as an example, the aluminum coil has a cylindrical structure. Referring to the orientation of the aluminum coil placed within the frame 10, the aluminum coil includes a lateral dimension (i.e., diameter), a vertical dimension (i.e., diameter), and a longitudinal dimension (i.e., length). Figure 5 Schematically shows the aluminum coils 20 stacked and placed within the frame 10, and in combination with Figure 1 the exemplary embodiment shown, the aluminum coils are placed such that their longitudinal dimension (i.e., length) is aligned with the front - rear direction of the frame, that is, the aluminum coils are placed between two adjacent underframe longitudinal rods 112 of the underframe 11. Taking the left - most aluminum coil as an example, this left - most aluminum coil corresponds to the above - mentioned longitudinal dimension L, the first lateral spacing D1, the second vertical spacing D2, and the third vertical spacing D3.
[0045] In one embodiment, compared with Figure 1 this embodiment, the underframe 11 only includes two underframe cross - rods 111 (i.e., omitting the middle underframe cross - rod 111 of the Figure 1 underframe), and the side frame 12 only includes two side - frame vertical rods 121 (i.e., omitting the middle side - frame vertical rod 121 of the Figure 1 side frame). In this case, in order to prevent the work materials from slipping out or falling through the space between the rods when they are contained within the frame 10, for the underframe 11, the longitudinal dimension L of the underframe (i.e., the longitudinal dimension L of the underframe longitudinal rod 112 itself) should be set to be less than the longitudinal dimension of the aluminum coil (i.e., length), and the first lateral spacing D1 should be set to be less than the lateral dimension of the aluminum coil (i.e., diameter); similarly, for the side frame 12, the second vertical spacing D2 should be set to be less than the vertical dimension of the aluminum coil (i.e., diameter). For the rear frame 13, when the rear - frame cross - rod 131 and the side - frame longitudinal rod 122 are connected in alignment with each other, in order to prevent the work materials from slipping out or falling through the space between adjacent rear - frame cross - rods 131, the third vertical spacing D3 should be set to be less than the vertical dimension of the aluminum coil (i.e., diameter); when the rear - frame cross - rod 131 and the side - frame longitudinal rod 122 are connected in an alternating manner, where the bottom - most rear - frame cross - rod 131 is connected between the bottom - most side - frame longitudinal rod 122 and the underframe cross - rod 111, in this case, the third vertical spacing D3 is naturally less than the vertical dimension of the aluminum coil (i.e., diameter), and the work materials will not slip out or fall through the space between adjacent rear - frame cross - rods 131.
[0046] In Figure 1 the illustrated embodiment, the chassis includes three chassis transverse rods 111, and the side frame 12 includes three side frame vertical rods 121. The middle chassis transverse rod 111 can be used to increase the structural strength and stiffness of the chassis, etc., and can be omitted as needed. Similarly, the middle side frame vertical rod 121 can be used to increase the structural strength and stiffness of the side frame, etc., and can be omitted as needed. Further, the middle chassis transverse rod 111 and the middle side frame vertical rod 121 can also provide other technical benefits. For example, they can be used as stoppers and supports for aluminum coils. In this case, even if the first transverse spacing D1 is set to be greater than or equal to the transverse dimension (i.e., diameter) of the aluminum coil and / or the second vertical spacing D2 is set to be greater than or equal to the vertical dimension (i.e., diameter) of the aluminum coil, due to the presence of the middle chassis transverse rod 111 and the middle side frame vertical rod 121, the aluminum coil cannot slide out or fall from the space between the corresponding rods.
[0047] Taking the diameter of the aluminum coil as 550 mm as an example, correspondingly, the first transverse spacing D1 should be set to be less than the transverse dimension of 550 mm of the aluminum coil, the second vertical spacing D2 should be set to be less than the vertical dimension of 550 mm of the aluminum coil, the third vertical spacing D3 should be set to be less than the vertical dimension of 550 mm of the aluminum coil. In addition, the longitudinal dimension L of the chassis should be set to be less than the longitudinal dimension of the aluminum coil.
[0048] To strengthen the fixation of the workpiece in the frame 10 and prevent the workpiece from moving in the frame, a stopper 15 can be provided in the frame 10. Refer to Figure 1 and Figure 2 , a plurality of stoppers 15 are provided on the chassis 11. The stopper 15 can be in the form of a triangular tab, which is only an example. The stopper 15 can adopt any other geometric shape and structural form. Specifically, a plurality of stoppers 15 are respectively provided at the joints of the chassis 11 and the two side frames 12. In the figure, 3 stoppers 15 are respectively provided at the joint of the chassis 11 and each side frame 12 and at the interface of the corresponding chassis transverse rod 111 and side frame vertical rod 121. In addition, a pair of stoppers 15 facing each other are provided at each joint between the chassis transverse rod 111 and the chassis longitudinal rod 112 of the chassis 11. To strengthen the structural strength between this pair of stoppers and the chassis, a stopper support 16 is provided along the corresponding chassis longitudinal rod 112 between each pair of stoppers 15. The stopper support 16 is in the form of a rod similar to the chassis longitudinal rod. These stoppers 15 face each other in the transverse direction, so that when the workpiece is placed in the space between adjacent chassis longitudinal rods 112, it abuts against the stoppers 15, and these stoppers 15 hold the workpiece in the workpiece frame.
[0049] Continue to refer to Figure 1, it can be seen that in each space formed between two adjacent chassis longitudinal rods 112 of the chassis 11 for receiving aluminum coils, on each chassis cross bar 111, a pair of stoppers 15 are arranged facing each other. They are arranged in pairs between adjacent chassis longitudinal rods 112 and form an opening that gradually expands upward, thereby forming a concave receiving space with a flat bottom similar to a V shape. When the aluminum coil is placed in this concave receiving space, the aluminum coil abuts against the stoppers 15 on the left and right sides and abuts against the rear frame 13 at the rear end. The paired stoppers together with the stopper support 16 limit the aluminum coil in the left and right lateral directions, preventing the aluminum coil from swinging or shaking left and right.
[0050] In addition, in order to prevent the aluminum coil from moving in the front-rear longitudinal direction, stoppers are arranged on the outermost chassis cross bar 111 of the chassis 11 and extend between the two side frames 12, not shown in the figure. In this case, the stopper is in the form of a long tab, so that the stopper extends vertically upward from the outermost chassis cross bar 111 of the chassis 11 by a certain height, similar to the form of a threshold, blocking the workpieces inside the frame and preventing the workpieces from moving or falling from the front side of the frame. Alternatively, the stopper can also be arranged in the form of multiple triangular tabs, so that the discrete stoppers are arranged on the outermost chassis cross bar 111 corresponding to Figure 1 the shown stoppers 15, so that when the aluminum coil is placed on the chassis, the front end of the aluminum coil abuts against the stopper and the rear end abuts against the rear frame 13, thereby limiting the aluminum coil in the front-rear longitudinal direction and preventing the aluminum coil from moving or falling from the front side of the frame.
[0051] The stoppers 15 and the stoppers can be fixedly connected to the chassis 11 and / or the side frames 12, such as by welding or screwing; or the stoppers 15 and the stoppers can be movably connected or detachably connected to the chassis 11 and / or the side frames 12, such as by hinging, snap connection, concave-convex shape matching, mortise and tenon connection or any other suitable form of movable connection or detachable connection.
[0052] See Figure 5, which shows that the work material (e.g., aluminum coil) is stored within the framework as described above. The figure shows a total of three layers of aluminum coils stacked within the framework. Among them, the bottom-layer aluminum coil is directly placed in the space between two adjacent longitudinal bars 112 of the chassis. The left and right sides of the aluminum coil abut against the stoppers 15, the rear end abuts against the rear frame, and the front end abuts against a stopper (not shown). The bottom-layer aluminum coil is well constrained; there are a total of two aluminum coils in the second layer, and each aluminum coil is placed between two adjacent aluminum coils in the bottom layer and abuts against the two aluminum coils by gravity. The rear end abuts against the chassis, and the aluminum coils in the second layer remain stationary by the friction between the aluminum coils; there are a total of three aluminum coils in the third layer. The middle aluminum coil is directly supported between the two aluminum coils in the second layer, and the left and right aluminum coils are respectively placed between the left and right side frames and one aluminum coil in the second layer, and also remain stationary by gravity and the friction between the aluminum coils. It should be noted that Figure 5 Taking the aluminum coil as an example of the work material shows the placement of the work material in the framework, but this is only an example and is not restrictive. The work material can also be work materials of any other shape and structure, and the framework can hold work materials of other quantities and arrangements. For example, the same number of work materials can be placed on each layer, such as three work materials on each layer. The bottom-layer work material is directly placed in the three receiving spaces of the chassis, and the work materials in the second and third layers can be stacked on top of each other. These work materials can be well constrained by the stoppers on the chassis and the stacking force and friction between the work materials, and thus remain stationary in the framework.
[0053] Although the front side and the top side of the work material framework 10 are shown as open openings in the figure, this is only an example, and the present disclosure is not limited thereto. In an alternative embodiment, a framework door can be provided on the front side of the work material framework 10. The framework door can be opened and closed to expose or enclose the receiving space. The framework door can be movably connected or detachably connected, such as hinged, snap-connected, concave-convex shape mating, mortise and tenon connection, or any other suitable form of movable connection or detachable connection. For example, when loading the work material, the framework door can be opened to facilitate the workers to load the work material onto the chassis; after loading the work material, for example, when it needs to be transported, the workers can close the framework door; or in a situation where the framework door is not needed, the framework door can be removed from the framework. The presence of the framework door can add a constraint in one direction to the contained work material, that is, prevent the work material from moving or falling from the front side of the framework 10, so that during the handling process, the work material is more firmly supported in the work material framework 10. The framework door can be similar to the rear frame 13, being a multi-bar grille or fence structure, which reduces the weight of the framework door and the use of materials while ensuring sufficient strength and stiffness of the framework door. When using a hinged connection, the framework door can be hinged to the chassis 11 or one of the side frames 12 on one side to facilitate the opening and closing of the framework door.
[0054] Similarly, in another alternative embodiment, a frame cover may be provided on the top side of the work material frame 10 to cover the work material within the frame 10 from above. The frame cover can be opened and closed to expose or enclose the accommodation space. The frame cover may be movably connected or detachably connected, such as by hinging, snap connection, concave-convex shape fitting, mortise and tenon connection, or any other suitable form of movable or detachable connection. For example, when loading the work material, the frame cover can be opened to facilitate the workers to load the work material onto the chassis; after loading the work material, for example, when it needs to be transported, the workers can close the frame cover; or in a situation where the frame cover is not needed, the frame cover can be removed from the frame. The presence of the frame cover can add a constraint in one direction to the contained work material, that is, prevent the work material from moving or falling from the top side of the frame 10, so that during the handling process, the work material is more firmly supported in the work material frame 10. The frame cover can be similar to the chassis 11, being a multi-bar grille or fence structure, reducing the weight of the frame cover while ensuring sufficient strength and stiffness of the frame cover, and reducing the use of materials. When using a hinged connection, the frame cover can be hinged to the rear frame 13 or one of the side frames 12 on one side, facilitating the opening and closing of the frame cover.
[0055] In addition, to facilitate the handling of the transfer tool, a transfer tool engagement member 14 is provided at the bottom of the chassis 11. When transferring the work material, the load-bearing member of the transfer tool engages with the transfer tool engagement member 14 of the frame 10 to carry and transport the frame 10 and the work material contained therein. Taking a common forklift as an example of the transfer tool, the forklift supports the frame 10 on the forks, and then raises the forks to lift the frame 10 from the ground and transport it to the target location (for example, the waste storage). In this case, the transfer tool engagement member 14 is two hollow tubes for the forks to insert. The internal contour and dimensions of the hollow tubes 14 match the forks, and the distance between the hollow tubes 14 corresponds to the distance between the forks. As shown in the figure, the hollow tubes 14 extend in the longitudinal direction and are fixedly connected to the bottom of the chassis 11, such as by welding, threaded connection, and other mechanical connection methods. Specifically, the hollow tubes 14 can be provided below the corresponding chassis longitudinal bars 112 of the chassis 11. Such a setting can make the force exerted by the forks act on the entire chassis longitudinal bar 112, optimize the load transfer path, and increase the structural stability of the frame under the action of the load.
[0056] The work material frame 10 is a multi-bar grille or fence structure, with a simple structure. It can reduce the use of materials and its own weight while ensuring the structural strength and stiffness, facilitating transportation, being easy to manufacture, and reducing costs. The work material frame 10 can be a modular component, that is, similar to ready-to-assemble furniture, the chassis 11, side frames 12, rear frame 13, and optional frame doors and frame covers are manufactured separately and then assembled together during use. The assembly process is simple and time-consuming.
[0057] Through the grid or fence-like structure of the frame 10, the freedom of movement of the work materials in multiple directions is restricted, keeping the work materials stationary or fixed, preventing the work materials from moving during stacking and transfer, improving safety, and greatly reducing or even eliminating potential safety hazards. By setting the distance between the rods, the work materials are prevented from moving away from the frame 10 during stacking and transfer. By allowing the frame 10 to carry multiple pieces of work materials at once, the transfer tool can carry multiple pieces of work materials at once, improving the transfer efficiency. By setting the stop members, the stationary or fixed state of the work materials is further ensured, preventing the work materials from moving during stacking and transfer, and further improving safety. In addition, the number and distance of the corresponding rods of the frame can be adjusted according to actual needs, so as to adapt to different types and sizes of work materials, and it has good versatility.
