Description

Technical Field

[0001] The utility model relates to a material tray loading and unloading device, belonging to the technical field of automation equipment. Background Art

[0002] A pallet is a tray used to hold and carry industrial materials. It is an indispensable tool in production lines and logistics systems. In traditional production and logistics operations, loading and unloading of pallets often requires manual work, which is not only inefficient but can also cause fatigue and injury to workers, especially when handling heavy or hazardous materials. In addition, manual operations may also cause material loss or quality problems due to improper operation.

[0003] On this basis, a tray loading and unloading device was invented. The tray loading and unloading device includes automatic feeding and unloading machinery, so that the tray automatically receives empty trays from the loading rack, automatically fills the tray with materials through the assembly area, and after the filling is completed, the tray filled with materials is automatically sent to the unloading rack. This automated process can improve production efficiency, reduce manual intervention, and reduce the risk of operational errors.

[0004] However, although the tray loading and unloading device improves the efficiency of a single process, in the traditional layout, the loading rack, assembly area and unloading rack are generally arranged in a straight line, resulting in only one flow channel loading and unloading operation on a production line at the same time, limiting the overall processing capacity. This linear process layout not only affects the overall production efficiency, but may also cause production bottlenecks during high demand, limiting the production capacity of the factory.

[0037] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] See also Figure 1 A tray loading and unloading device 100 shown in a preferred embodiment of the present application includes a linear module 1, a placing component 2 and a lifting component 3.

[0042] See also Figure 5 In this embodiment, the linear module 1 is a linear motor, and the lifting assembly 3 can move along the axis direction of the linear motor through the drive of the linear motor. Optionally, in other embodiments, the linear module 1 can also be a linear guide and a cylinder, and the lifting assembly 3 can move along the axis direction of the linear guide under the drive of the cylinder.

[0043] Along the axial direction of the linear module 1, the linear module 1 is sequentially formed with a first material placement area (unnumbered), an assembly area (unnumbered) and a second material placement area (unnumbered). The first material placement area and the second material placement area are respectively located at the two ends of the linear module 1 for loading and unloading the material tray, and the assembly area is located in the middle of the linear module 1 for loading materials into the material tray.

[0044] See also Figures 2 to 4 The material placing components 2 are two groups arranged in the first material placing area and the second material placing area, including a first material placing component 201 arranged in the first material placing area and a second material placing component 202 arranged in the second material placing area. Since the structures of the first material placing component 201 and the second material placing component 202 are the same, the subsequent description will only take the structure of the first material placing component 201 as an example, and the structure of the second material placing component 202 will not be repeated.

[0045] Each set of material placing components 2 includes a base 21 arranged in the first material placing area, and a material placing rack 22 slidably arranged on the base 21, wherein the material placing rack 22 is formed with an upper material rack 221 and a lower material rack 222 for placing material trays. The upper material rack 221 is used to load empty material trays, and the lower material rack 222 is used to load full material trays.

[0046] The loading rack 221 forms a first filling space (unnumbered) for placing material trays, and a loading port 2211 is opened at the bottom of the loading rack 221 for moving material trays in the first filling space into / out of the loading rack 221. The loading rack 221 is provided with a first supporting mechanism 224 that can move relative to the loading port 2211, and the first supporting mechanism 224 can be switched between a first position and a second position.

[0047] Specifically, the first supporting mechanism 224 includes a side clamping cylinder 2241 and a side clamping block 2242, wherein the side clamping cylinder 2241 is arranged on the material rack 22, and the side clamping block 2242 is connected to the output shaft of the side clamping cylinder 2241. The side clamping block 2242 can be converted between a first position and a second position under the drive of the output shaft. The side clamping block 2242 can move relative to the side of the material rack 221 to protrude from the side of the material rack 221, that is, move to the opposite side, so that the distance between the opposite side clamping blocks 2242 is smaller than the length or width of the material tray, thereby clamping the material tray.

[0048] Furthermore, in order to improve the stability during clamping, four sets of first abutting mechanisms 224 are provided. In this embodiment, along the axis direction of the linear module 1, the four sets of first abutting mechanisms 224 are relatively arranged on both sides of the loading rack 221. Optionally, in other embodiments, the four sets of first abutting mechanisms 224 can also be relatively arranged on the four sides of the loading rack 221, in a cross distribution.

[0049] The unloading rack 222 forms a second filling space (unnumbered) for placing material trays, and a unloading port 2221 for moving material trays in the second filling space into / out is provided at the bottom of the unloading rack 222. A second supporting mechanism 225 that can move relative to the unloading port 2221 is provided on the unloading rack 222, and the second supporting mechanism 225 can be switched between a third position and a fourth position.

[0050] See also Figure 5 and Figure 6 The second supporting structure 225 includes a rotating member 2251, which is arranged on the unloading rack 222 and can be relatively turned between a third position and a fourth position. When the unloading rack 222 is in the third position, the distance between the two relative rotating members 2251 is less than the length or width of the material tray; when the unloading rack 222 is in the fourth position, the distance between the two relative rotating members 2251 is not less than the length or width of the material tray.

[0051] In this embodiment, the rotating member 2251 includes a rotating portion 2253 and a supporting portion 2252. The rotating portion 2253 is arranged on the side of the unloading rack 222 and can rotate around an axis connected to the unloading rack 222. The supporting portion 2252 is connected to the rotating portion 2253. When it is in the third position, the distance between the two opposite supporting portions 2252 is smaller than the length or width of the material tray.

[0052] Initially, the second abutting mechanism 225 is located at the third position. When the material tray is lifted upward from the bottom of the lower rack 222, the material tray contacts the abutting portion 2252, driving the abutting portion 2252 to move upward, thereby rotating the rotating portion 2253. Subsequently, during the lifting process, the abutting portion 2252 contacts the side wall of the material tray. When the material tray rises to a certain height, that is, when it is located at the fourth position, the abutting portion 2252 is separated from the material tray and no longer contacts the side wall of the material tray. In this embodiment, the second abutting mechanism 225 also includes a spring (not shown) arranged between the lower rack 222 and the rotating member 2251, and the rotating member 2251 automatically returns to the third position through the spring. Finally, the material tray is moved downward to contact the abutting portion 2252. At this time, the abutting portion 2252 will not be pressed to rotate downward, thereby completing the clamping of the material tray on the lower rack 222.

[0053] In another embodiment, the rotating member 2251 can also be flipped between the third position and the fourth position by a driving mechanism, such as a motor or a cylinder. This structure is relatively common and will not be described in detail here.

[0054] In this embodiment, brackets 223 are provided on the circumference of the loading rack 221 and the unloading rack 222. The brackets 223 surround a filling space (not numbered) for filling material trays. The filling space includes a first filling space and a second filling space. Multiple material trays can be loaded through the filling space, thereby improving the automation efficiency and avoiding repeated loading of empty material trays.

[0055] Furthermore, a first sensor 2231 for detecting whether the tray is full is provided at the top of the bracket 223, and a second sensor 2232 for detecting whether there is a tray is provided at the bottom of the bracket 223. By providing the first sensor 2231 and the second sensor 2232, the loading status of the tray can be detected in real time, and the information can be transmitted to other mechanisms in a timely manner, thereby improving the automation efficiency.

[0056] In this embodiment, when placing the empty material tray on the loading rack, in order to reduce production costs, loading is performed manually. Therefore, in order to facilitate placing the empty material tray on the loading rack 221, the loading rack 22 can slide on the base 21 along the direction perpendicular to the axis of the linear module 1 on the horizontal plane, and has a working position and a preparation position. When the loading rack 22 is in the working position, the lifting assembly 3 can enter the loading rack 221 and the unloading rack 222; when the loading rack 22 is in the preparation position, the empty material tray is loaded in the loading rack 221. A moving cylinder 23 is provided on the base 21, and the moving cylinder 23 drives the loading rack 22 to transform between the working position and the preparation position.

[0057] In other embodiments, the empty trays may be loaded directly by a robotic arm. In this case, there is no need to provide a moving cylinder 23 to drive the material rack 22 to transform between the working position and the preparation position.

[0058] See also Figure 7 There are two groups of jacking components 3, which are slidably arranged on the linear module 1. One group of jacking components 3 can move between the first material loading area and the assembly area, and the other group of jacking components 3 can move between the second material loading area and the assembly area.

[0059] Specifically, the lifting assembly 3 includes a lifting base 31, a servo motor 32, a screw rod 33, a transmission belt 34, a sliding member 35 and a lifting platform 36. Among them, the lifting base 31 is slidably set on the linear module 1 and can move along the axis of the linear module 1. Furthermore, a limit sensor 311 for limiting the lifting platform 36 is provided on the lifting base 31. The servo motor 32 is fixed on the lifting base 31 to provide a driving force for the lifting platform 36 to move in a vertical direction. The screw rod 33 is arranged adjacent to the servo motor 32, the transmission belt 34 connects the output end of the servo motor 32 and the screw rod 33, and the sliding member 34 is slidably set on the screw rod 33. The lifting platform 36 is slidably set on the lifting base 31, connected to the sliding member 34, and can move in a vertical direction under the drive of the servo motor 32.

[0060] The working process of the tray loading and unloading device 100 in the present application is as follows: First, in the preparation stage, the material rack 22 is moved to the preparation position, and the upper material rack 221 is manually loaded with empty material trays. After the empty material trays are filled, the material rack 22 is moved to the working position. Subsequently, the jacking assembly 3 moves to the bottom of the upper material rack 221 along the axis direction of the linear module 1, and the jacking platform 36 is lifted upward until it contacts the empty material tray. The side clamps 2242 move to both sides and open, so that the empty material tray is completely supported by the jacking platform 36. The jacking platform 36 drops to the height of a tray, and the side clamps 2242 move to the opposite side to clamp the remaining empty material trays, thereby obtaining an empty material tray on the jacking platform 36. Then, the jacking platform 36 moves the empty material tray to the assembly area for material filling. After the empty tray is filled with materials, the lifting platform 36 moves the tray to the lower part of the lower rack 222, the lifting platform 36 moves up, the second abutting mechanism 225 rotates to avoid, and changes from the first position to the second position, so that the tray moves to the upper part of the lower rack 222, the second abutting mechanism 225 returns to the first position, the lifting platform 36 moves down, so that the tray falls on the lower rack 222, and the second abutting mechanism 225 clamps it. Finally, the lifting platform 36 returns to the lower part of the upper rack 221, and the next tray loading and unloading operation is performed.

[0061] In the present application, the lifting group 3 moves on the linear module to the loading rack 221 to obtain the empty material tray, then moves to the assembly area to fill the empty material tray with materials, and finally moves to the unloading rack to unload the materials, thereby completing the loading and unloading of the material tray. Since the material placement assembly 2 and the lifting assembly 3 are both provided in the first material placement area and the second material placement area, the two groups of lifting assemblies 3 can alternately go to the assembly area to complete the process of filling the empty material tray with materials, and then return to the first material placement area and the second material placement area to load and unload the material tray, thereby realizing the loading and unloading operations of two flow channels on one production line at the same time, and improving the efficiency of loading and unloading.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
