[0051] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0052] In the production process of sheet metal, after the sheet metal is processed by a stamping device or other operating equipment and is discharged as a finished product, it needs to be transported to a stacking device for stacking and transfer. The present invention provides a stacking line implementation scheme for realizing neat stacking of workpieces, which is applicable to a wide range of workpiece sizes, and the stacking work can maintain continuity and stable stacking efficiency.

[0053] like Figure 1-15 The figure is a schematic diagram of an embodiment of a stacking operation line provided by the present invention.

[0054] Please refer to Figure 1-15, this embodiment includes a support frame 100, a trolley 110, a trolley guide rail 120, a lifting assembly 130, a buffer material fork 140, a beating device 200 and a conveyor belt 300. The support frame 100 supports the beating device 200 and the buffer material fork 140, which are located above the lifting assembly 130. The lifting assembly 130 is arranged at the lifting position below the beating device 200, the trolley guide rail 120 is arranged below the beating device 200, the section of the trolley guide rail 120 covers the position of the lifting position, and the trolley 110 can move along the trolley guide rail 120. The conveyor belt 300 is arranged adjacent to the beating device 200, and is used to transport the workpiece to the beating device 200 for beating, positioning and centering.

[0055] Specifically, a lifting assembly 130 is provided below the middle of the trolley guide rail 120, and the trolley guide rail 120 is arranged along the second direction. When the trolley 110 moves along the trolley guide rail 120 to the middle of the trolley guide rail 120, the trolley 110 is located directly above the lifting assembly 130 and below the beating device 200. The lifting assembly 130 lifts the trolley 110 upward to approach the blanking position of the beating device 200. The workpiece is transported to the beating device 200 by the conveyor belt 300. During the process of the workpiece being dropped from the conveyor belt 300 to the trolley 110, the beating device 200 beats and centers the workpiece so that the workpiece is neatly stacked on the trolley 110. The lifting component 130 gradually lowers the height of the trolley 110 according to the amount of workpieces stacked on the trolley 110 or the stacking thickness until the load capacity of the trolley 110 reaches a predetermined value or a maximum, and the trolley 110 returns to the trolley guide rail 120. The trolley 110 moves along the trolley guide rail 120 to the head end or the tail end of the trolley guide rail 120, and the stacked workpieces are transferred from the trolley 110 through subsequent equipment (stacking transfer device). After the workpiece stack on the trolley 110 is transferred, the trolley 110 returns to the lifting position and repeats the above stacking process.

[0056] In one embodiment, the beating device 200 is provided with a beating area, and the beating area coincides with the orthographic projection of the lifting position in the vertical direction, and the bearing area of ​​the trolley 110 can be larger than the area of ​​the beating area. The trolley 110 approaches or moves away from the beating area through the lifting assembly 130 at the lifting position, and the beating device 200 is used for beating and centering the workpiece, and the trolley 110 is used for carrying the workpiece. The receiving fork frame 146 of the buffer material fork 140 can extend into the bottom of the beating area, and is used to carry the workpiece, specifically when the trolley 110 reaches the carrying capacity, or when the trolley 110 is transferred for stacking, the temporary bearing of the workpiece, thereby maintaining the continuous feeding of the conveyor belt 300.

[0057] In one embodiment, the trolley 110 moves to the lifting position along the trolley guide rail 120, and the lifting assembly 130 lifts the trolley 110 located at the lifting position close to the beating area to a first predetermined height. The trolley 110 carries the beating device 200 to beat the centered workpiece, and the lifting assembly 130 lowers its height according to the amount of workpiece carried by the trolley 110. When the trolley 110 reaches the predetermined load of the workpiece or the height of the trolley 110 is at the lower limit position of the lifting assembly 130, the trolley 110 leaves the lifting position along the trolley guide rail 120. This process is usually the initial working process of the stacking operation line, and at this time, the buffer material fork 140 does not temporarily carry the workpiece. The number of trolleys 110 can be multiple.

[0058] In one embodiment, when there is no trolley at the lifting position or the trolley 110 reaches a predetermined load, the material receiving fork frame 146 extends into the lower part of the beating area to carry the workpiece after the beating device 200 beats and centers it. The trolley 110 moves to the lifting position along the trolley guide rail 120, and the lifting assembly 130 lifts the trolley 110 at the lifting position close to the beating area to a second predetermined height, and the support block 111 of the trolley 110 contacts the workpiece carried by the material receiving fork frame 146, and the support block 111 supports and lifts the workpiece. At this time, the workpiece carried by the material receiving fork frame 146 is transferred to the trolley 110, and then the material receiving fork frame 146 withdraws from the lower part of the beating area, completing the transfer of the temporarily stacked workpiece. This process is usually the process of transferring the temporary stacking of the material receiving fork frame 146 to the trolley 110. After the transfer is completed, the trolley 110 continues to receive the workpiece fed by the conveyor belt 300 to the beating device 200 to beat and center it.

[0059] The lifting assembly 130 lowers its height according to the amount of workpieces carried by the trolley 110 . When the trolley 110 reaches a predetermined load of the workpieces or the height of the trolley 110 is at the lower limit of the lifting assembly 130 , the trolley 110 leaves the lifting position along the trolley guide rail 120 .

[0060] In one embodiment, when the receiving fork frame 146 is located directly below the beating area to carry the workpiece, the conveyor belt 300 conveys the workpiece at the first feeding speed. When the trolley 110 is located at the lifting position to carry the workpiece and the receiving fork frame 146 does not carry the workpiece, the conveyor belt 300 conveys the workpiece at the second feeding speed, and the first feeding speed is less than the second feeding speed. Due to the temporary load capacity limit of the receiving fork frame 146, the conveying speed of the conveyor belt 300 needs to be adjusted so that the temporary load time of the receiving fork frame 146 matches the round trip time of the unloading process of the trolley 110.

[0061] In one embodiment, if Figure 3-5As shown, the lifting assembly 130 includes a first frame 131, a lifting cylinder 132, a lifting guide column 133 and a supporting platform 134.

The trolley 110 is provided with positioning holes 112, and the distribution of the positioning holes 112 corresponds to the distribution of the positioning pins 1341. The positioning holes 112 are used for the positioning pins 1341 to insert and position. When the trolley 110 moves to the lifting position, the lifting cylinder 132 drives the support platform 134 to move upward, so that the positioning pins 1341 are inserted into the positioning holes 112, so as to prevent the trolley 110 from shifting laterally when it is lifted or lowered.

[0066] The trolley 110 is provided with a driving motor 113, a transmission rod 114, a driving wheel 115 and a driven wheel 116.
