[0002] A progressive die refers to a stamping die that uses a strip of stamping raw material and simultaneously completes multiple stamping processes at several different stations on a set of dies during one stamping stroke of a press.

[0003] In existing production, for the stamping forming of sheet parts, the progressive die method is mostly used. However, the production blanking and palletizing of the progressive die are both carried out manually. When blanking and palletizing manually, the punching press needs to stop for waiting, resulting in low production efficiency. At the same time, due to the fast production rhythm, the labor intensity of manual handling is high, causing great waste of labor and resources.

[0004] Therefore, there is an urgent need for an automatic palletizing device and method to solve the technical problems existing in the existing manual blanking and palletizing. Summary of the Invention

[0030] The present invention will be further described below in conjunction with the drawings

[0031] Figure 1 shows an automatic palletizing device according to the present application, including a counting and storing mechanism 1, a material fetching mechanism 2 and a control unit. The counting and storing mechanism 1 is used for counting and palletizing the processed materials. The material fetching mechanism 2 is arranged close to the counting and storing mechanism 1 and is used for clamping the materials that reach the preset quantity in the counting and storing mechanism 1 and moving the materials to the preset position. The control unit is electrically connected to the counting and storing mechanism 1 and the material fetching mechanism 2. After receiving the signal that the materials in the counting and storing mechanism 1 reach the preset quantity, the control unit controls the material fetching mechanism 2 to perform the actions of clamping the materials that reach the preset quantity and moving them to the preset position. The automatic palletizing device of the present application realizes the automatic palletizing, clamping and transferring of the processed materials, the processing machine tool does not need to stop waiting, the production efficiency is high, and the labor cost is saved. At the same time, the abnormality caused by human error is also avoided

[0032] Among them, the materials transferred by the material fetching mechanism 2 can be sheet parts after continuous die stamping. Correspondingly, the machine tool 3 is a punching press, and a punching die 31 is installed on the punching press 3. When the sheet parts are stamped on the punching die 31, the sheet parts slide onto the belt line 32, and the belt line 32 drives the sheet parts to move (as shown by the arrow A in Figure 1 ) until the sheet parts slide onto the counting and storing mechanism 1. The counting and storing mechanism 1 counts and palletizes the sheet parts that slide onto it. When the quantity of the sheet parts reaches the preset quantity, the counting and storing mechanism 1 sends a corresponding signal to the control unit. After receiving this signal, the control unit controls the material fetching mechanism 2 to clamp and transfer the sheet parts that reach the preset quantity on the counting and storing mechanism 1

[0033] Preferably, the automatic palletizing device of the present application further includes a palletizing insert plate 4. After the material fetching mechanism 2 clamps the sheet parts, it transfers them to the palletizing insert plate 4, which is convenient for subsequent processes of the sheet parts

[0034] Figure 2 Shows an enlarged view of the counting storage mechanism 1 according to the present application. As Figure 2 shown, the counting storage mechanism 1 includes a bracket 11, a storage member 12, a counter 13, and a sensor 14.

[0035] Among them, the bracket 11 forms a ramp for the sheet parts to slide downward. The storage member 12 is used to store the sheet parts that slide off the bracket 11. The storage member 12 can move up and down. When the storage member 12 moves downward, it can release the sheet parts it stores. The counter 13 is used to count the sheet parts entering the storage member 12. When the number of sheet parts in the storage member 12 reaches a preset number, the counter 12 sends a first signal to the control unit. After receiving the first signal, the control unit controls the storage member 12 to move downward so that the sheet parts are separated from the storage member 12. The sensor 14 is arranged on the bracket 11 and below the storage member 12. When the storage member 12 moves downward to the detection range of the sensor 14, the sensor 14 sends a second signal to the control unit; after receiving the second signal, the control unit controls the storage member 12 to reset to wait for the next batch of materials.

[0036] Specifically, the storage member 12 includes a release plate 121, a left baffle 122, and a right baffle 123. The release plate 121 is mechanically connected to the power mechanism 126 (refer to Figure 3 ), and can move up and down under the drive of the power mechanism 126. The power mechanism 126 can be a telescopic cylinder. The left baffle 122 and the right baffle 123 are respectively arranged on both sides of the pallet 121 and outside the bracket 11, and are used to limit the materials. By arranging the left baffle 122 and the right baffle 123 outside the bracket 11, after the storage member 12 moves downward to release the sheet parts, the sheet parts can be supported by the bracket 11 and slide along the bracket 11 for subsequent processes.

[0037] Preferably, as Figure 4 shown, a stop bar 111 is provided on the bracket 11. The stop bar 111 is used to block the sheet parts that slide off the bracket 11 after leaving the storage member 12, facilitating the picking mechanism 2 to pick them up. Specifically, when the number of sheet parts in the storage member 12 reaches a preset number, the control unit controls the storage member 12 to move downward. The sheet parts in the storage member 12 gradually separate from the storage member 12 and fall on the slide bar of the bracket 11. Then, the sheet parts that fall on the slide bar of the bracket 11 slide along the bracket 11 to the position of the stop bar 111 and are blocked by the stop bar 111. The picking mechanism 2 picks up the sheet parts at the position of this stop bar 111 and transfers them.

[0038] Refer again to Figure 3, both the left baffle 122 and the right baffle 123 include a rotating rod 124 and a baffle 125 fixedly connected to the end of the rotating rod 124. The rotation of the rotating rod 124 can drive the baffle 125 to rotate relative to the pallet 121 to adjust the relative position between the baffle 125 and the pallet 121. When the length of the sheet metal part is relatively long, the rotating rod 124 can be rotated to rotate the baffle 125 to an outwardly inclined position. When the length of the sheet metal part is relatively short, the rotating rod 124 can be rotated to rotate the baffle 125 to an inwardly inclined or vertical position.

[0039] The bracket 11 is arranged on the punching press 3 through the adjusting member 15. The adjusting member 15 is fixedly connected to the bracket 11. Preferably, the bracket 11 and the adjusting member 15 are connected together by welding. Figure 3 In the illustrated embodiment, the adjusting member 15 is an angle steel. The adjusting member 15 is movably connected to the punching press 3 so that the bracket 11 can move along the width direction of the punching press 3. By arranging the bracket 11 on the machine tool, the space can be utilized to the maximum extent, and the space utilization rate on the side of the machine tool line can be improved.

[0040] Specifically, as Figure 4 shown, the adjusting member 15 and the punching press 3 are movably connected in the following manner: a first groove is formed at a position corresponding to the adjusting member 15 on the punching press 3, and a second groove 151 is formed on the adjusting member 15 and is matched with the first groove. The first groove and the second groove 151 extend along the width direction of the punching press 3, and a fixing member is passed through the first groove and the second groove 151 to connect the adjusting member 15 to the punching press. When it is necessary to finely adjust the relative position between the adjusting member 15 and the punching press 3, the adjusting member 15 can be moved. After the adjusting member 15 is moved to the required position, a fixing member is passed through the first groove and the second groove 151 to fix the two.

[0041] It can be understood that the bracket 11 may not be integrally connected to the punching press 3, but is independently placed at the discharging end of the punching press 3.

[0042] In addition, it should be noted that mounting members 152 are provided at both ends of the adjusting member 15. The mounting members 152 are provided with mounting holes and fixing holes perpendicular to the mounting holes. The end of the rotating rod 124 can pass through the mounting holes, and the rotating rod 124 is fixed to the mounting member 152 by passing a screw 153 or other fixing member through the fixing holes.

[0043] In Figure 5 , the material taking mechanism 2 includes a robotic arm 21 and a fixture 22. The fixture 22 is arranged at the free end of the robotic arm 21 and can move under the drive of the robotic arm 21. Among them, the length of the fixture 22 can be adjusted to clamp sheet metal parts of different sizes.

[0044] As Figure 6As shown, the fixture 22 includes a fixed rod 221, a telescopic cylinder 222, and a clamping plate 223. The fixed rod 221 is fixedly connected to the robotic arm 21. Preferably, a connecting member 2211 is provided at the middle position of the fixed rod 221, and the fixed rod 221 is connected to the robotic arm 21 through the connecting rod 2211. Telescopic cylinders 224 are respectively provided at both ends of the fixed rod 221, and the free ends of the telescopic cylinders 224 are provided with clamping plates 223, and the clamping plates 223 can move driven by the telescopic cylinders 224. This structure can be used for materials of different sizes, improving the universality of the device.

[0045] The following specifically describes the working process of the automatic palletizing device according to Figure 1 :

[0046] When the sheet metal part 100 (as Figure 7 shown) is stamped on the punching die 31, the sheet metal part slides onto the conveyor belt 32, and the conveyor belt 32 drives the sheet metal part to move (in the direction indicated by the arrow A in Figure 1 ) until the sheet metal part slides onto the storage part 12. The counter 13 is used to count the sheet metal parts entering the storage part 12. When the number of sheet metal parts in the storage part 12 reaches the preset quantity, the counter 12 sends a first signal to the control unit. After receiving the first signal, the control unit controls the storage part 12 to move downward so that the sheet metal part detaches from the storage part 12. The sheet metal part that detaches from the storage part 12 falls onto the bracket 11 and slides along the bracket 11 to the position of the stop bar 111 and is blocked by the stop bar 111. The picking mechanism 2 picks up the sheet metal part at the position of the stop bar 111 and transfers it. When the storage part 12 moves downward to the detection range of the sensor 14, the sensor 14 sends a second signal to the control unit; after receiving the second signal, the control unit controls the storage part 12 to reset to wait for receiving the next batch of materials. While the control unit controls the storage part 12 to move downward to release the materials, it controls the fixture 22 to move to the position of the stop bar 111 to pick up the materials and move the picked-up materials to the palletizing insert 4. Thus, a complete automatic palletizing process is completed.

[0047] The automatic palletizing device of the present application realizes the automatic palletizing, picking and transferring of the processed materials. The processing machine tool does not need to stop for waiting, with high production efficiency and labor cost savings. At the same time, it also avoids the abnormalities caused by human errors and improves the production stability.
