Description

Technical Field

[0001] This invention relates to the field of automotive parts processing equipment technology, specifically to a pallet rack and method for placing stamped semi-finished steel plates. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] In the stamping process, for symmetrical parts such as side panels and door outer panels, the first-stage stamping of both side panel components uses the same semi-finished products. The second stage, due to the symmetrical structure, requires a portion of the first-stage semi-finished products to be flipped 180° before further production. To facilitate this flipping, a pallet is placed on the ground, and semi-finished steel plates are placed on the pallets. Before flipping, another pallet is placed on the top surface of the semi-finished steel plates using lifting equipment such as a crane, and then fed into a flipping machine for a 180° flip. Therefore, two pallet placements are required, which is time-consuming, labor-intensive, and reduces production efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a pallet rack for stamped semi-finished steel plates, which can reduce the number of pallet placements and improve production efficiency.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] In a first aspect, embodiments of the present invention provide a stamped semi-finished steel plate pallet placement rack, including a main support frame. The main support frame is provided with a plurality of pallet support mechanisms. Each pallet support mechanism includes a fixing member fixed to the main support frame. The fixing member is rotatably connected to a support member. A lower limit member is provided below the support member to provide support force to the support member. An upper limit member is provided above the support member so that after the support member rotates upward at a set angle and separates from the pallet, it can fall back under its own gravity.

[0007] Optionally, the main support frame includes a bottom frame and a top frame, with multiple vertical pillars between the bottom frame and the top frame, connecting the bottom frame and the top frame into a whole, and the pallet support mechanism is fixed on the vertical pillars.

[0008] Optionally, both the bottom frame and the top frame are rectangular frames, with vertical supports positioned between the corners of the top frame and the bottom frame. The pallet support mechanism is fixed to the vertical supports to support the corners of the pallet.

[0009] Optionally, the main support frame is provided with a multi-layer pallet support mechanism, with multiple pallet support mechanisms on the same layer. The distance between adjacent pallet support mechanisms in different layers is different to achieve support for pallets of different sizes.

[0010] Optionally, the fastener includes two fixing plates, with a rotating shaft between the two fixing plates, and one end of the support member is rotatably connected to the fixing plates via the rotating shaft.

[0011] Optionally, the lower limit member is positioned below the support member at a predetermined location so that when the support member rotates to contact the lower limit member, the support member is in a horizontal state.

[0012] Optionally, both the lower limit member and the upper limit member are fixedly connected to the main support frame.

[0013] Optionally, the support member includes a rotating part, which is rotatably connected to the main support frame. The upper surface of the rotating part is fixed with a support part, which is used to support the pallet.

[0014] Secondly, embodiments of the present invention provide a method for placing stamped semi-finished steel plate pallets on a shelf, comprising the following steps:

[0015] The semi-finished steel plates are placed on the lower pallet in advance, and the upper pallet is placed on the stamping semi-finished steel plate pallet placement shelf in advance, and supported by the pallet support mechanism.

[0016] Transport the lower pallet and semi-finished steel plate directly beneath the upper pallet;

[0017] The lower pallet and semi-finished steel plate are lifted until the upper surface of the finished steel plate contacts the bottom surface of the upper pallet. The lifting continues, and the support rotates upward under the action of the lower pallet. When the support separates from the lower pallet, it rotates back to the initial position under its own weight.

[0018] The upper pallet, semi-finished steel plate, and lower pallet are transported to the outside of the main support frame for easy delivery to the tipping equipment.

[0019] Optionally, the upper pallet is provided with a support column, which can contact the support member, and the pallet support mechanism supports the upper pallet through the support column.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. The shelving and method of the present invention, since the support member and the fixing member are rotatably connected, when the support member supports the upper pallet, the placed semi-finished steel plate and the lower pallet can be moved from below the upper pallet to the top using the equipment. The rotation of the support member causes the lower pallet to separate from the support member. During the upward movement of the semi-finished steel plate, the upper pallet is placed on the semi-finished steel plate, so that the upper pallet is placed during the lifting process of the semi-finished steel plate using the equipment, without the need to use the lifting equipment to place the upper pallet, saving the time of placing the pallet once and improving work efficiency.

[0022] 2. The shelf and method of the present invention are provided with an upper limit member, which can limit the rotation angle of the support member so that after the support member rotates upward by a set angle and separates from the pallet, it can fall back under its own gravity without the need for manual adjustment of the position of the support member, which facilitates the placement of the next pallet and is convenient to use.

[0023] 3. The shelf and method of the present invention are provided with a multi-layer pallet support mechanism. The distance between adjacent pallet support mechanisms in different layers is different to achieve support for pallets of different sizes, thereby improving the applicability of the entire placement shelf.

Therefore, they should not be construed as limitations on this invention.

[0029] Example 1

[0030] This embodiment provides a rack for placing stamped semi-finished steel plate pallets, such as... Figure 1 The device includes a main support frame, inside which are multiple pallet support mechanisms for supporting the pallets.

[0031] The main support frame includes a top frame 1 and a bottom frame 2 arranged in parallel. In this embodiment, both the top frame 1 and the bottom frame 2 are rectangular frames, which are formed by four channel steels and the ends of adjacent channel steels are welded and fixed.

[0032] Multiple vertical columns 3 are provided between the top frame 1 and the bottom frame 2. The top end of the vertical column 3 is welded and fixed to the top frame 1, and the bottom end of the vertical column 3 is welded and fixed to the bottom frame 2. The top frame 1 and the bottom frame 2 are connected into a whole by the vertical columns 3.

[0033] The vertical columns 3 are made of channel steel. Vertical columns 3 are set between the four corners of the top frame 1 and the bottom frame 2. The top frame 1, the bottom frame 2 and the vertical columns 3 constitute the overall structure of the main support frame.

[0034] The main support frame is equipped with multiple pallet support mechanisms 4. There are multiple pallet support mechanisms 4 in the same layer. The distance between adjacent pallet support mechanisms 4 in different layers is different to support pallets of different sizes.

[0035] In this embodiment, two layers of pallet support mechanisms are provided to support two different sizes of pallets. The upper pallet support mechanism is used to support the larger pallet, and the lower support mechanism is used to support the smaller pallet.

[0036] This setup improves the overall usability of the shelving unit.

[0037] In this embodiment, the distance between two vertical pillars 3 on the same side along the length of the main support frame is greater than the length of the larger pallet, so as to facilitate the placement of the pallet inside the main support frame.

[0038] The pallet support mechanism 4 is installed on the surface of the vertical column 3 perpendicular to the length direction of the main support frame.

[0039] like Figure 2 As shown, the pallet support mechanism includes a fixing member 4-1, wherein the fixing member of the upper pallet support mechanism is directly fixed to the vertical column 3. The fixing member is rotatably connected to a support member, which is used to support the pallet. A lower limit member is provided below the support member. The lower limit member is fixedly set. After the support member rotates to a set posture, it can contact the lower limit member. The support member can provide support force to the pallet through the lower limit member.

[0040] In this embodiment, when the support member rotates to a horizontal state, the lower limit member can contact the support member, thereby enabling the support member to provide support force. With this setting, the support member can provide more stable support force to the pallet.

[0041] An upper limit stop is provided above the support member, which is fixed to the vertical column. The support member can rotate upward to contact the upper limit stop. After the support member separates from the tray, it can fall back to a horizontal state under its own gravity.

[0042] The fastener includes two parallel fixing plates 4-1, which are fixed to the vertical column 3, and a rotating shaft 4-2 is provided between the two fixing plates.

[0043] The support member 4-3 includes a rotating part that is rotatably connected to a rotating shaft. A support part is provided on the upper surface of the rotating part. The support part is a support plate used to support the pallet.

[0044] In this embodiment, the upper limit member 4-4 is an L-shaped plate, with its vertical part fixed to the vertical column and its horizontal part located at the upper end of the vertical part.

[0045] The lower limit member 4-5 adopts a protrusion set on the fixing member 4-1. The lower limit member 4-5 is relatively fixed to the vertical column 3 through the fixing member 4-1. When the support member 4-3 rotates to the horizontal state, the protrusion can contact the bottom surface of the rotating part, thereby applying a bearing force to the support member.

[0046] The structure of the lower pallet support mechanism 4 is the same as that of the upper pallet support mechanism 4. The only difference is that the fixing component is fixed on the adjusting beam 5 and fixed on the surface of the adjusting beam 5 perpendicular to the length direction of the main support frame. The adjusting beam 5 is fixed on the surface of the vertical column 3 perpendicular to the length direction of the main support frame. By setting the adjusting beam, the distance between the two pallet support mechanisms along the length direction of the main support frame in the lower layer is smaller than the distance between the two corresponding pallet support mechanisms in the upper layer, thus realizing the support of pallets with smaller size.

[0047] Example 2

[0048] This embodiment provides a method for placing stamped semi-finished steel plate pallets on shelves as described in Embodiment 1:

[0049] The upper pallet 6 is placed on the pallet placement shelf in advance. In this embodiment, the upper pallet support mechanism 4 is used. Support columns are set at the four corners of the upper pallet. The support columns are in contact with the support plates of the upper pallet support mechanism 4 of the four vertical columns 3 respectively, and the support plates are used to support it.

[0050] The semi-finished steel plate 7 is placed on the lower pallet 8. A forklift is used to lift the lower pallet 8 containing the semi-finished steel plate 7, and the forklift transports the semi-finished steel plate 7 and the lower pallet 8 directly under the upper pallet 6.

[0051] The forklift is used to lift the lower pallet 8 and the semi-finished steel plate 7 until the semi-finished steel plate 7 contacts the upper pallet 6. The forklift continues to lift the lower pallet 8 and the semi-finished steel plate 7. At this time, the upper pallet 6, the semi-finished steel plate 7 and the lower pallet 8 are lifted together. When the support column of the lower pallet 8 contacts the support plate, the support plate rotates upward as the lower pallet 8 is lifted. When the support plate disengages from the support column of the lower pallet 8, it falls back to contact the lower limit piece 4-5 under its own gravity, maintaining a horizontal state to facilitate the placement of the next upper pallet.

[0052] The forklift removes the lower pallet 8, the semi-finished steel plate 7, and the upper pallet 6 from the main support frame and sends them into the tilting mechanism.

[0053] The shelving system of this embodiment allows for the placement of upper pallets on semi-finished steel plates during forklift lifting, eliminating the need for lifting equipment and saving time on pallet placement. This improves work efficiency. Furthermore, after the support plate rotates upwards to a set angle and detaches from the lower pallet, it can fall back under its own weight without requiring manual adjustment of the support plate's position, facilitating the placement of the next pallet and making it convenient to use.

[0054] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
