Abstract
Description
Technical Field
[0001] The present application relates to the technical field of product storage, and in particular to a pallet mechanism and a stereoscopic warehouse rack suitable for DfMA finished product storage. Background Art
[0002] DfMA, the full name of which is Design for Manufacturing and Assembly, is a design method for product manufacturing and assembly. It refers to a comprehensive analysis of the product's material selection, processing technology, assembly process, inspection method, maintenance process, etc. during the product design stage, so that the products designed by engineers have good manufacturability and assemblability.
[0003] After the DfMA finished product is produced, it needs to be temporarily stored for later use. The current pallet mechanism is generally composed of a chassis and enclosures set on both sides of the chassis. The pallet is used to support the DfMA finished product, and the enclosure is used to limit the DfMA finished product to prevent the DfMA finished product from falling off the chassis as much as possible.
[0004] With respect to the above-mentioned related technologies, the pallet mechanism generally needs to correspond to the size of the corresponding DfMA finished product. If the size of the pallet mechanism is larger than the size of the DfMA finished product, there is space for the DfMA finished product to move during storage. The DfMA finished product is prone to relative collision with the enclosure in a vibrating environment. In the long run, the DfMA finished product or the enclosure will be damaged. Utility Model Content
[0005] In order to help store and protect DfMA finished products, the present application provides a tray mechanism and a stereoscopic warehouse rack suitable for storing DfMA finished products.
[0006] The present application provides a pallet mechanism suitable for DfMA finished product storage, which adopts the following technical solution:
[0007] First,
[0008] A pallet mechanism suitable for DfMA finished product storage, comprising:
[0009] Chassis;
[0010] Two enclosures are installed on both sides of the chassis and are arranged opposite to each other. The two enclosures can slide relative to the chassis so that the two enclosures can move closer to each other or move away from each other;
[0011] A linkage assembly is arranged between the chassis and the enclosure;
[0012] The trigger component is arranged on the chassis. When the DfMA finished product enters the chassis, the DfMA finished product can press down the trigger component and drive the two enclosures to approach each other through the linkage component. When the DfMA finished product leaves the chassis, the trigger component rises and drives the two enclosures to move away from each other through the linkage component.
[0013] By adopting the above technical solution, when the DfMA finished product has not entered the pallet mechanism, the distance between the two enclosures is relatively wide, which facilitates the DfMA finished product to enter between the two enclosures; after the DfMA finished product enters the pallet mechanism, the gravity of the DfMA finished product is fed back to the trigger component, and then fed back to the linkage component through the trigger component, and the linkage component drives the two enclosures to approach each other, and clamps the two sides of the DfMA finished product. The pallet mechanism of the present application can effectively limit and clamp the DfMA finished product during the storage of the DfMA finished product, reduce the possibility of movement of the DfMA finished product during storage, reduce the frequency of collision between the DfMA finished product and the enclosure, and play a role in protecting the DfMA finished product.
[0014] Optionally, the linkage assembly includes a first return spring and a first wedge block, wherein the first return spring is arranged in the chassis to pull the enclosure toward the center of the chassis, and the first wedge block is arranged in the chassis and fixedly connected to the enclosure;
[0015] The trigger assembly includes a trigger rod, a second return spring and a second wedge block. The trigger rod slides through the chassis in a direction perpendicular to the chassis surface. The second return spring is used to push the trigger rod out of the chassis. The second wedge block is fixed to one end of the trigger rod and is located inside the chassis. The wedge surface of the second wedge block slides and abuts against the wedge surface of the first wedge block. When the trigger rod moves away from the chassis, the first wedge block can push the second wedge block away from the center of the chassis so that the two barriers can move away from each other.
[0016] By adopting the above technical solution, the enclosure is driven by a spring to clamp the DfMA finished product, so that the contact between the two is elastic, and the tray mechanism has good shock absorbing performance, which further plays a role in protecting the DfMA finished product.
[0017] Optionally, the wedge-shaped cross-section height of the first wedge-shaped block is greater than the wedge-shaped cross-section height of the second wedge-shaped block.
[0018] By adopting the above technical solution, the transmission of the first wedge block and the second wedge block is made more stable, and at the same time the enclosure has a larger moving distance to adapt to the clamping of DfMA finished products of different sizes.
[0019] Optionally, a third wedge block is provided at one end of the trigger rod outside the chassis, and the wedge surface of the third wedge block faces the feeding direction.
[0020] By adopting the above technical solution, when the DfMA finished product moves along the tray mechanism feeding mode, the third wedge block is helpful for the DfMA finished product to press down the trigger rod.
[0021] Optionally, a first connecting rod and a second connecting rod are connected between the enclosure and the first wedge block, the first connecting rod is vertically fixed to the bottom of the enclosure and is slidably connected to the chassis, the second connecting rod is fixed to the end of the first connecting rod away from the enclosure, the extension direction of the second connecting rod is consistent with the sliding direction of the enclosure, the end of the second connecting rod away from the first connecting rod is fixedly connected to the first wedge block, one end of the first return spring is fixedly connected to the first connecting rod, and the other end is connected to the chassis, and the extension direction of the center line of the first return spring is consistent with the sliding direction of the enclosure.
[0022] By adopting the above technical solution, the first return spring has a larger expansion and contraction amount, and thus the enclosure has a larger moving distance to accommodate more DfMA finished products of different sizes.
[0023] Optionally, the enclosure includes a first cross beam, a first vertical beam and a first cross beam, wherein two first cross beams are provided and the two first cross beams are parallel to each other, one of the first cross beams is slidably connected to the chassis, the first vertical beam is vertically fixed between the two first cross beams, and the first cross beam is fixed on the diagonal of the quadrilateral structure formed by the first cross beam and the first vertical beam.
[0024] By adopting the above technical solution and utilizing the stability of the triangle, the purpose of further strengthening the tray mechanism is achieved.
[0025] Optionally, the length of the first cross beam on the side close to the chassis is greater than the length of the first cross beam on the side away from the chassis, and a second cross beam is connected between the ends of the two first cross beams.
[0026] By adopting the above technical solution, the stability of the enclosure structure is improved while it is beneficial for the stacker to pick up and place the DfMA finished products.
[0027] Optionally, the linkage assembly and the trigger assembly are arranged on a side of the chassis away from a feeding direction.
[0028] By adopting the above technical solution, when the DfMA finished product is just placed in the tray mechanism, the enclosure does not move. When the DfMA finished product moves to the predetermined position along the feeding direction, the DfMA finished product triggers the trigger component, and the enclosure is driven by the linkage component to approach the DfMA finished product and clamp the DfMA finished product. This design method can reduce the resistance encountered by the DfMA finished product when it moves, which is conducive to improving the convenience of taking and placing the DfMA finished product.
[0029] Optionally, the linkage components and trigger components are arranged in multiple groups from the center of the chassis to the edge of the chassis.
[0030] By adopting the above technical solution, the enclosure is driven by the joint action of multiple groups of linkage components and trigger components. When the DfMA finished product moves along the feeding direction, the multiple groups of linkage components and trigger components are gradually triggered. When the triggered linkage components and trigger components reach a sufficient number, the enclosure starts to move and clamps the DfMA finished product. Therefore, the DfMA finished product can be placed in different positions, and the clamping force of the enclosure on the DfMA finished product can be adjusted to further improve the adaptability of the enclosure clamping.
[0031] Second,
[0032] A three-dimensional warehouse rack comprises a frame body, on which the above-mentioned tray mechanism suitable for DfMA finished product storage is installed.
[0033] In summary, the present application includes at least one of the following beneficial technical effects:
[0034] 1. The tray mechanism of the present application can effectively limit and clamp the DfMA finished products during the storage process, reduce the possibility of movement of the DfMA finished products during storage, reduce the frequency of collision between the DfMA finished products and the enclosure, play a role in protecting the DfMA finished products, and also facilitate the placement of the DfMA finished products.
[0035] 2. Use the spring to drive the enclosure to clamp the DfMA finished product, so that the contact between the two is elastic, so that the tray mechanism has good shock absorption performance, and further plays a role in protecting the DfMA finished product.
[0036] 3. The enclosure is driven by the joint action of multiple groups of linkage components and trigger components. When the DfMA finished product moves along the feeding direction, multiple groups of linkage components and trigger components are gradually triggered. When the triggered linkage components and trigger components reach a sufficient number, the enclosure starts to move and clamps the DfMA finished product. Therefore, the DfMA finished product can be placed in different positions, and the clamping force of the enclosure on the DfMA finished product can be adjusted to further improve the adaptability of the enclosure clamping.

DETAILED DESCRIPTION
[0044] The following is combined with Figure 1-5 This application is described in further detail.
[0045] The present application embodiment discloses a tray mechanism suitable for DfMA finished product storage. Figure 1 and Figure 2 The tray mechanism includes a chassis 10, a barrier 20, a linkage assembly 30 and a trigger assembly 40.
[0046] There are two enclosures 20 and the two enclosures 20 are installed on both sides of the chassis 10. The two enclosures 20 are slidably connected to the chassis 10 along the width direction of the chassis 10. The linkage assembly 30 is arranged between the chassis 10 and the enclosures 20. The trigger assembly 40 is arranged on the chassis 10 and connected to the linkage assembly 30. When the DfMA finished product enters the chassis 10, the DfMA finished product can press down the trigger assembly 40 and drive the two enclosures 20 to approach each other through the linkage assembly 30. When the DfMA finished product leaves the chassis 10, the trigger assembly 40 rises and drives the two enclosures 20 to move away from each other through the linkage assembly 30.
[0047] Reference Figure 1 The chassis 10 is composed of crisscross chassis cross beams 11 and chassis vertical beams 12. In a preferred embodiment, the chassis 10 is composed of 4 chassis cross beams 11 and 9 chassis vertical beams 12.
[0048] The enclosure 20 includes a first cross beam 21, a first vertical beam 22 and a first cross beam 23. The first cross beams 21 are arranged in two and the two first cross beams 21 are parallel to each other. One first cross beam 21 is slidably connected to the chassis 10. The first vertical beam 22 is vertically fixed between the two first cross beams 21. The first cross beam 23 is fixed on the diagonal of the quadrilateral structure formed by the first cross beam 21 and the first vertical beam 22.
[0049] At the same time, the length of the first cross beam 21 on the side close to the chassis 10 is greater than the length of the first cross beam 21 on the side away from the chassis 10, and a second cross beam 24 is connected between the ends of the two first cross beams 21. The second cross beam 24 is provided to reinforce the enclosure 20 on the one hand, and on the other hand, to provide the tray mechanism with a relatively wide space at the inlet and outlet, so as to facilitate the subsequent stacker to pick up and place the DfMA finished products. In another embodiment, the tray mechanism can also be picked up and placed by a stacker.
[0050] In a preferred embodiment, a fence 20 is composed of two first cross beams 21 , five first vertical beams 22 , four first cross beams 23 , and two second cross beams 24 .
[0051] Reference Figure 2 and Figure 3 The linkage assembly 30 includes a first connecting rod 31, a second connecting rod 32, a first return spring 33 and a first wedge block 34. The first connecting rod 31 is vertically fixed to the bottom of the first beam 21 and is slidably connected to the chassis 10. The second connecting rod 32 is fixed to one end of the first connecting rod 31 away from the first beam 21. The extension direction of the second connecting rod 32 is consistent with the sliding direction of the first beam 21. The end of the second connecting rod 32 away from the first connecting rod 31 is fixedly connected to the first wedge block 34. One end of the first return spring 33 is fixedly connected to the first connecting rod 31, and the other end is fixedly connected to the chassis 10. The center line extension direction of the first return spring 33 is consistent with the sliding direction of the first beam 21.
[0052] The first return spring 33 has a pulling force to pull the first cross beam 21 toward the center of the chassis 10 , so that the enclosure 20 can be pulled by the pulling force of the first return spring 33 to clamp the DfMA finished product.
[0053] Reference Figure 2 and Figure 3 The trigger assembly 40 includes a trigger rod 41, a second return spring 42 and a second wedge block 43. The trigger rod 41 slides through the chassis 10 in a direction perpendicular to the surface of the chassis 10. One end of the second return spring 42 is fixedly connected to the side wall of the trigger rod 41, and the other end is fixedly connected to the chassis 10. The extension direction of the second return spring 42 is consistent with the sliding direction of the trigger rod 41. The second return spring 42 has a thrust to push the trigger rod 41 out of the chassis 10.
[0054] The second wedge block 43 is fixed to the end of the trigger rod 41 and is located inside the chassis 10. The wedge surface of the second wedge block 43 slides against the wedge surface of the first wedge block 34. When the second return spring 42 pushes the trigger rod 41 away from the chassis 10, the first wedge block 34 can push the second wedge block 43 away from the center of the chassis 10 so that the two enclosures 20 can move away from each other.
[0055] Under normal conditions, the thrust of the second return spring 42 is greater than the tension of the first return spring 33, so that the two enclosures 20 are in a state of being away from each other under normal conditions. When the DfMA finished product presses down the trigger rod 41, the enclosure 20 approaches the center of the chassis 10 under the tension of the second return spring 42, thereby clamping the DfMA finished product.
[0056] In a preferred embodiment, the height of the wedge-shaped cross section of the first wedge block 34 is greater than the height of the wedge-shaped cross section of the second wedge block 43. This makes the transmission of the first wedge block 34 and the second wedge block 43 more stable, and at the same time, the enclosure 20 has a larger moving distance to adapt to the clamping of DfMA finished products of different sizes.
[0057] In another preferred embodiment, referring to Figure 3 and Figure 4 The trigger rod 41 is disposed at one end outside the chassis 10 with a third wedge block 411, and the wedge surface of the third wedge block 411 faces the feeding direction. When the DfMA finished product enters the chassis 10 along the feeding direction, the DfMA finished product contacts the wedge surface of the third wedge block 411 and pushes the trigger rod 41 downward, thereby driving the enclosure 20 to approach the DfMA finished product through the linkage assembly 30.
[0058] Reference Figure 1 and Figure 2 The linkage assembly 30 and the trigger assembly 40 are arranged on the side of the chassis 10 away from the feeding direction, and the linkage assembly 30 and the trigger assembly 40 are arranged in multiple groups from the center of the chassis 10 to the edge of the chassis 10. When the DfMA finished product is just placed in the tray mechanism, the enclosure 20 does not move. When the DfMA finished product moves along the feeding direction, multiple groups of linkage assemblies 30 and trigger assemblies 40 are gradually triggered. When the triggered linkage assemblies 30 and trigger assemblies 40 reach a sufficient number, the enclosure 20 starts to move and clamps the DfMA finished product. Therefore, the DfMA finished product can be placed in different positions, and the clamping force of the enclosure 20 on the DfMA finished product can be adjusted to further improve the adaptability of the enclosure 20 clamping.
[0059] The implementation principle of a pallet mechanism suitable for storing DfMA finished products in the embodiment of the present application is as follows: when the DfMA finished product has not entered the pallet mechanism, the distance between the two enclosures 20 is relatively wide, which facilitates the DfMA finished product to enter between the two enclosures 20; after the DfMA finished product enters the pallet mechanism, the gravity of the DfMA finished product is fed back to the trigger component 40, and is fed back to the linkage component 30 through the trigger component 40, and the linkage component 30 drives the two enclosures 20 to approach each other, and clamps the two sides of the DfMA finished product. The pallet mechanism of the present application can effectively limit and clamp the DfMA finished product in the process of storing the DfMA finished product, reduce the possibility of movement of the DfMA finished product during storage, reduce the frequency of collision between the DfMA finished product and the enclosure 20, and play a role in protecting the DfMA finished product.
[0060] The present application also discloses a stereoscopic library rack, referring to Figure 5 , including a frame 50, on which the above-mentioned pallet mechanism suitable for storing DfMA finished products is installed. When it is necessary to take out the DfMA finished products stored on the pallet mechanism, the stacker can transfer the pallet mechanism together with the DfMA finished products from the frame 50. The present application solution can stably store the goods in the pallet mechanism, and reduce the resistance when the DfMA finished products move, so as to realize the automatic, safe and stable transfer of the goods to the warehouse outlet.
[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
