Description

Technical Field

[0001] The utility model relates to the technical field of punching line feeding, in particular to an automatic punching line feeding device. Background Art

[0002] After the stamping line completes a series of processing steps to produce stamped parts, they are sent to the corresponding loading box by the unloading device. The traditional unloading device is only a slope with a certain slope, allowing the stamped parts to slide along the slope into the loading box at the end of the slope. This device has some defects. First, some stamped parts may not slide smoothly due to excessive friction, and they need to be pushed forward manually. Second, the angle of the slope is fixed, resulting in a fixed falling direction of the stamped parts, which easily causes excessive accumulation of stamped parts in local positions in the loading box. The stamped parts cannot be loaded smoothly before the loading box is fully utilized, and manual rearrangement is required. Both increase manpower consumption. Third, when the loading box is full of stamped parts, in order to replace the loading box, the unloading operation needs to be suspended, which reduces the unloading efficiency. Fourth, the loading box is a certain distance away from the end of the slope. When the stamped parts fall, there is a certain probability of damage due to impact, which is not good for the quality of the stamped parts. Utility Model Content

DETAILED DESCRIPTION

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Example:

[0028] like Figures 1 to 5 As shown, this embodiment provides an automatic unloading device for a stamping line, comprising a bottom plate 1, on which a box placing frame 2 located in the front and a conveying platform 3 located in the rear are provided, vertical plates 4 are symmetrically provided on the left and right sides of the top of the conveying platform 3, a movable plate 5 is provided on the inner side of the vertical plate 4, and a material transfer roller 6 is connected to the inner surface of the movable plate 5 so as to rotate evenly from front to back, and a double-track wheel 7 is provided at the upper end of the rotating shaft of the material transfer roller 6, and the front and rear adjacent double-track wheels 7 are connected by an annular transmission belt 8 for transmission, a telescopic rod A9 is provided on the outer side of the vertical plate 4, and the telescopic direction of the telescopic rod A9 is along the left and right direction, and the movable rod of the telescopic rod A9 passes through the vertical plate 4 and is connected to the outer side of the movable plate 5, The front end of the top of the conveying platform 3 is rotatably connected to a slide plate 10, and the front end of the conveying platform 3 is provided with a rotating component 11 for adjusting the angle of the slide plate 10. The bottom of the box placing frame 2 is slidably connected to the top of the bottom plate 1, and the bottom plate 1 is provided with a translation component 12 for driving the box placing frame 2 to move along the left and right directions. A pair of left-right symmetrical box placing grooves 13 are provided on the top of the box placing frame 2, and a loading box 14 can be placed in the box placing grooves 13. A lifting component 15 is provided at the front end of the top of the bottom plate 1. When unloading, any one of the two box placing grooves 13 moves to the front of the conveying platform 3, and the movable end of the lifting component 15 can extend into the box placing groove 13 aligned with the conveying platform 3 and lift up the corresponding loading box 14.

[0029] The rotating material transfer roller 6 helps the stamping parts to move along the conveyor 3, reducing manpower consumption. The motor 38, the double-track wheel 7 and the ring transmission belt 8 are used together, and multiple material transfer rollers 6 are synchronously driven by one motor 38 to rotate. There is no need to equip each material transfer roller 6 with a motor 38 to drive its rotation, thereby reducing equipment costs. The material transfer roller 6 is installed on the moving plate 5, and the moving plate 5 can be translated in the left and right directions through the telescopic rod A9 on the vertical plate 4, so that the material transfer rollers 6 on the left and right sides can be adjusted to the position matching the width of the stamping parts, expanding the scope of application of the device. The angle of the sliding plate 10 can be adjusted by the rotating component 11, thereby changing the falling position of the stamping parts, helping the stamping parts to be evenly distributed in the loading box 14. The box placing slot 13 aligned with the conveying platform 3 can be changed by the translation assembly 12. When the box placing slot 13 currently aligned with the conveying platform 3 is full of stamping parts, the translation assembly 12 is controlled to move another box placing slot 13 to the front of the conveying platform 3 to allow the new loading box 14 to continue to receive materials. The staff replaces the loading box 14 from the removed box placing slot 13 to ensure that the unloading operation can be carried out continuously and improve the work efficiency. The height of the loading box 14 can be adjusted by the lifting assembly 15 to reduce the height required for the stamping parts to fall from the sliding plate 10 into the loading box 14, thereby reducing the probability of the stamping parts being damaged due to impact.

[0030] Furthermore, the rotating assembly 11 includes a connecting rod 16, a fixed seat 17 and a telescopic rod B18. A connecting rod 16 is provided below the front end of the conveying platform 3, a fixed seat 17 is provided in the middle of the connecting rod 16, a telescopic rod B18 pointing to the sliding plate 10 is provided on the fixed seat 17, and a rotating seat 19 is provided at the front end of the movable rod of the telescopic rod B18. The rotating seat 19 has rolling rollers 20 rotatably connected along the left and right directions on the left and right sides. The sliding plate 10 is symmetrically provided with rolling grooves 21 along the front and back directions on the left and right sides facing downward, and the rolling rollers 20 are horizontally inserted into the rolling grooves 21 and roll along the rolling grooves 21.

[0031] The rolling roller 20 is adjusted by the connecting rod 16B, and the angle of the slide plate 10 is changed by pushing and pulling the rolling roller 20, thereby changing the position of one end of the slide plate 10 away from the conveyor platform 3, thereby adjusting the falling position of the stamping parts sliding along the slide plate 10, so that the stamping parts will not be excessively accumulated at the fixed position of the loading box 14, and can fall at different positions of the loading box 14 to achieve reasonable stacking.

[0032] Furthermore, the translation assembly 12 includes a connecting plate 22 and a telescopic rod C23. A slide rail 24 along the left and right direction is provided at the front end of the top of the base plate 1. A slide groove 25 corresponding to the slide rail 24 is provided at the bottom of the box placing frame 2. The slide groove 25 is slidably connected to the slide rail 24. An installation groove 26 is symmetrically provided on the front and rear sides of the slide rail 24 at the top of the base plate 1. A telescopic rod C23 along the left and right direction is provided in the installation groove 26. A connecting plate 22 corresponding to the telescopic rod C23 is provided at the bottom of the right end of the box placing frame 2. The movable rod end of the telescopic rod C23 is connected to the connecting plate 22. An extension groove 27 for the connecting plate 22 to enter and exit is provided at the right end of the installation groove 26.

[0033] By using the slide rail 24 and the slide groove 25 together, the moving direction of the box placing frame 2 is limited to prevent the loading box 14 placed on the box placing frame 2 from deviating from the correct position. The telescopic rod C23 is connected to the box placing frame 2 via the connecting plate 22, and the box placing frame 2 is moved by telescopic movable rod of the telescopic rod C23, thereby meeting the need to change the loading box 14 aligned with the conveying platform 3 when necessary.

[0034] Furthermore, the lifting assembly 15 includes a telescopic rod D28 and a support plate 29. A pair of front-to-back symmetrical telescopic rods D28 are provided at the front end of the top of the base plate 1. The telescopic rods D28 are along the vertical direction, and the top of the movable rod of the telescopic rod D28 is provided with a support plate 29 along the horizontal direction. When unloading, the bottom of the loading box 14 abuts against the top of the support plate 29.

[0035] When unloading, the support plate 29 abuts against the loading box 14 . When the telescopic rod D28 changes the height of the support plate 29 , the height of the loading box 14 held up by the support plate 29 will also change.

[0036] Furthermore, a slot 30 corresponding to the support plate 29 is provided at the bottom of the charging box 14, and when unloading, the top of the support plate 29 extends into the slot 30. By extending the top of the support plate 29 into the slot 30, the probability of the charging box 14 detaching from the support plate 29 is reduced, ensuring smooth unloading operation.

[0037] Furthermore, the box placing frame 2 is in the shape of a rectangle, and a partition plate 31 is provided in the middle of the box placing frame 2 along the front-to-back direction. The partition plate 31 separates the box placing frame 2 into two box placing grooves 13 on the left and right. An extension plate 32 is provided in the box placing groove 13 in the four directions of front, back, left and right. When the loading box 14 is placed in the box placing groove 13, the extension plate 32 is abutted against the bottom of the loading box 14, and the extension plate 32 and the partition plate 31 are higher than the lowest point of the support plate 29.

[0038] The loading box 14 placed in the box placing slot 13 is supported by the extension plate 32. The size of the extension plate 32 should be such that the loading box 14 in the box placing slot 13 is stably placed, and the extension plate 32 should avoid blocking the path of the support plate 29 extending into the box placing slot 13 and supporting the loading box 14. The extension plate 32 needs to be higher than the lowest point of the support plate 29 to prevent the loading box 14 placed on the extension plate 32 from hitting the support plate 29 when moving with the box placing frame 2. The partition plate 31 needs to be higher than the lowest point of the support plate 29 to prevent the partition plate 31 from being mounted on the support plate 29 when the box placing frame 2 moves, thereby affecting the normal movement of the box placing frame 2.

[0039] Furthermore, the front and rear ends of the movable plate 5 facing outward are symmetrically provided with guide rods 33 along the left and right directions, and the vertical plate 4 is provided with guide holes 34 for the guide rods 33 to pass through. The guide rods 33 and the guide holes 34 are used in combination to guide the movable plate 5, so that the translational movement of the movable plate 5 is more stable.

[0040] Furthermore, a buffer plate 35 is provided in the charging box 14, and a plurality of springs 36 are evenly connected between the bottom of the buffer plate 35 and the bottom of the charging box 14. The instantaneous impact on the stamping parts falling into the charging box 14 is reduced, and the probability of the stamping parts being damaged due to the impact is reduced.

[0041] Furthermore, the top of the conveying platform 3 is evenly rotated from front to back and connected with a support roller 37. The support roller 37 rolls against the stamping part to reduce the friction between the stamping part and the conveying platform 3, increase the conveying speed of the stamping part, and reduce the wear of the stamping part.

[0042] The working principle and use process of this utility model:

[0043] The staff aligns the rear end of the conveyor platform 3 with the discharge end of the stamping line, and puts the loading boxes 14 into the two box placement slots 13 of the box placement frame 2 respectively, moves one of the loading boxes 14 to the front of the conveyor platform 3, and then lifts the loading box 14 to a suitable height through the lifting assembly 15, operates the telescopic rod A9 to adjust the position of the movable plate 5, and makes the positions of the left and right transfer rollers 6 match the width of the stamping parts, completing the preliminary preparations. The stamping line starts and begins to produce stamped parts. The stamped parts fall onto the rear end of the conveyor table 3. The transfer roller 6 driven by the motor 38 drives the stamped parts to move to the front end of the conveyor table 3 and fall onto the slide plate 10. Then the stamped parts slide along the slide plate 10 into the loading box 14. In the process of placing the stamped parts into the loading box 14, firstly, the rotating component 11 is required to allow the slide plate 10 to reciprocate within a certain angle range so that the stamped parts can fall evenly throughout the loading box 14. Secondly, the lifting component 15 is required to slowly lower the height of the loading box 14 to leave enough space for the stamped parts to fall into the loading box 14. When the loading box 14 is full, the loading box 14 should have fallen on the extension plate 32, and the support plate 29 should have been separated from the loading box 14 and lowered to the lowest point. The other loading box 14 that has not started loading is moved to the front end of the conveyor platform 3 through the translation component 12, and then the lifting component 15 lifts the loading box 14. The staff will unload the loading box 14 filled with stamping parts and replace it with a new loading box 14 in the box placement slot 13. The loading and unloading operations of the loading box 14 are repeated until the stamping line stops outputting stamping parts and the unloading operations of all stamping parts are completed.

[0044] The above are only specific application examples of the utility model, and do not constitute any limitation on the protection scope of the utility model. Any technical solution formed by equivalent transformation or equivalent replacement falls within the protection scope of the utility model.
