Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a stacking device. Background Technology

[0002] Currently, there are dedicated buffer devices for long and bulky items such as base frames. These devices use a lift to raise the base frame, then use cylinders to push the support components to support the heavy object before the lift platform lowers. Repeating these steps completes the stacking. To use the item, simply reverse the steps. This stacking method stores items upwards. For storing long and bulky items, a lift platform is typically used. When the material is conveyed to the lift platform, the platform is raised to be level with the material. After conveying, the platform lowers until the bottom of the first layer of material is level with the bottom of the subsequent conveyed material, forming a stack. Once the stack is complete, it can be hoisted and transported as a whole. This stacking method stores items downwards.

[0003] Stacking devices that store upwards can store multiple parts and can also be used for stacking and conveying. However, this type of device requires the cooperation of cylinders and connection to pneumatic devices. The stacking device as a whole is relatively complex and is generally suitable for assembly line operations. However, it has certain storage difficulties when the parts are not produced on the assembly line, especially when it is a problem of overall hoisting that affects production efficiency.

[0004] Downward stacking is a simple way to achieve stacking operations, but it is generally suitable for stamped parts, especially side plates and square plates, which are quickly stacked and then transported away as a whole by overhead crane. This method works well for parts, but it cannot be used for large components due to limited storage capacity, especially when storing downwards, as it is limited by the lifting height of the elevator and cannot stack large components. Utility Model Content

[0005] The purpose of this invention is to provide a stacking device that can be used to stack components such as end frames when the parts being produced are not located on the production line, while minimizing the use of pneumatic devices and reducing the occupation of overhead cranes.

[0006] This utility model includes an elevator, a conveyor frame, a conveyor assembly, a guide component, a stop block, a support frame, and a lug assembly.

[0007] The elevator is positioned between two conveyor frames, each equipped with a set of conveying components. Guide vanes are located on the outer sides of both ends of each conveyor component. A stop block is fixed to the upper part of one end of each conveyor component. Several support frames are positioned outside the conveyor frames, corresponding to each other. Lug assemblies are movably connected to the upper ends of the support frames. Each lug assembly includes a rotating frame, a connecting plate, and a counterweight. The bottom-opening channel steel rotating frame is connected to both sides of the support frame via pivot pins. The rotating frame is connected to the connecting plate, and a counterweight is fixed to the lower part of the connecting plate.

[0008] Preferably, the conveying assembly includes a support groove and a conveying roller. The support groove is a channel steel type with an open top, and several grooves with corresponding positions are opened on both sides of the support groove, with the conveying roller disposed between the corresponding grooves.

[0009] Preferably, the two conveyor frames are connected by a connecting rod.

[0010] Preferably, the guide includes a support base, a connecting rod, and a rotating wheel. The inverted L-shaped support base is fixed to the outer sides of both ends of the conveying assembly. The lower end of the connecting rod passes through the support base, and the upper end of the connecting rod is inserted into the rotating wheel.

[0011] Compared with the prior art, this utility model has the following advantages: it can be used to stack components such as end frames when the parts being produced are not on the production line, and can minimize the use of pneumatic devices and reduce the occupation of overhead cranes.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Example 1

[0021] exist Figure 1 and Figure 5 As shown in the schematic diagram of this utility model, a stacking device includes a lift, a conveyor frame, a conveying assembly, a guide component, a stop block, a support frame, and a lug assembly. The lift 1 is positioned between two conveyor frames 2, which are connected by a connecting rod 3. Each of the two conveyor frames is equipped with a set of conveying assemblies, each including a support groove and a conveying roller. The support groove 4 is an open-top channel steel type, with several corresponding grooves on both sides of the support groove, and a conveying roller 5 is positioned between the corresponding grooves. A guide component is provided on the outer side of both ends of the support groove, comprising a support seat, a connecting rod, and a rotating wheel. An inverted L-shaped support seat 6 is fixed to the outer side of both ends of the support groove, the lower end of the connecting rod 7 passes through the support seat, and the upper end of the connecting rod is inserted into the rotating wheel 8. A stop block 9 is fixed to the upper part of one end of the support groove. The processed container end frame is conveyed to the conveyor frame and moved by the conveying assembly. The stop block prevents the container end frame from falling off the conveyor frame. Several support frames 14 are positioned outside the conveyor frame, corresponding to each other. A support lug assembly is movably connected to the upper end of the support frame. The support lug assembly includes a rotating frame, a connecting plate, and a counterweight. The bottom-opening channel steel rotating frame 12 is connected to both sides of the support frame via pivot pins 13. The rotating frame is connected to the connecting plate 10, and a counterweight 11 is fixed at the lower part of the connecting plate.

[0022] In use, this invention transfers the first completed container end frame to a conveyor frame. The conveyor assembly moves the end frame, and a stop block prevents it from detaching. Once the first completed container end frame touches the stop block, the lower part of the counterweight of the lug assembly rests on top of the first container end frame. At this point, the elevator rises, causing the first container end frame to slowly rise. Because the counterweight rests on top of the first container end frame, the connecting plate of the lug assembly causes the rotating frame to rotate upwards. However, due to the counterweight, the rotating frame only rotates slightly and does not flip 90 degrees. As the elevator continues to move the first container end frame upwards, when the bottom of the first container end frame is higher than the rotating frame, the rotating frame quickly rotates downwards. At this point, the elevator lowers the first container end frame, placing it on top of the rotating frame of the lug assembly. The elevator then continues to descend to its initial position.

[0023] After the second container end frame is produced, it is transferred to a conveyor frame. The conveyor system moves the end frame, and stops prevent it from detaching. When the second end frame touches a stop, the lower part of the counterweight of the lug assembly rests on top of the second end frame, while the upper part of the counterweight supports the first end frame. The elevator then rises, causing both the first and second end frames to slowly ascend. Because the counterweight rests on top of the second end frame, the connecting plate of the lug assembly causes the rotating frame to rotate upwards. However, due to the counterweight, the rotating frame only rotates slightly and does not flip 90 degrees. As the elevator continues to move the second end frame upwards, when the bottom of the second end frame is higher than the rotating frame, the rotating frame quickly rotates downwards. At this point, the elevator lowers both the first and second end frames, and the second end frame lands on top of the rotating frame of the lug assembly. Similarly, when multiple container end frames are placed together, an overhead crane is used to move them to the designated storage location.

[0024] When the container end frame moves on the conveyor, the guides on both sides can prevent the container end frame from shifting during the conveying process.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
