Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of logistics handling equipment, in particular to a lifting and discharging stacking mechanism for realizing efficient and continuous automatic discharging. BACKGROUND

[0002] With the rising labor costs, factories have an increasingly strong demand for automatic loading, which has given rise to many companies researching automatic loading devices, and specific application products have been launched. The stacking methods of existing products can be roughly divided into two categories: one is to use a conveyor to directly convey and stack, that is, the conveyor conveys single pieces of material into the car compartment for automatic stacking, which needs to be moved to the next station to stack the second piece of material after the conveyor automatically stacks a piece of material, which is difficult to control and has low efficiency; the other is to set a stacking mechanism on the automatic loading device, which arranges the box-type materials in a row and then pushes the whole row of materials into the car compartment, which can improve the stacking efficiency, but the existing stacking mechanisms have the problems of discontinuous discharging and slow stacking, that is, the stacking mechanism needs to return to the fixed position to discharge and stack again after stacking a row of materials, and the return time and waiting time of the mechanism seriously restrict the improvement of the loading efficiency.

[0003] There are many examples of stacking mechanisms in existing automatic loading devices. The Chinese utility model patent CN 215159357U discloses a stacking mechanism of an automatic loading device, which has the following shortcomings: the material taking and placing mechanism (7) needs to move back and forth on the horizontal moving mechanism (8) to receive materials, which has low stacking efficiency.

[0004] The stacking device (15) of the Chinese utility model patent CN 209209960U discloses a pushing loading machine and loading system, in which the pushing and retracting driving member (121) can drive the pushing member (123) to move away from the pushing channel, the pushing member (123) is located above the stacking device (15), and the pushing and retracting driving member (121) can drive the pushing member (123) to move away from the pushing channel from above the stacking device (15). It has the following shortcomings: first, the stacking device (15) needs to move back and forth to receive materials, which cannot realize continuous discharging and reduces the loading efficiency; second, the pushing mechanism (12) is located above the fixed material taking position channel of the rack, which cannot move with the stacking device (15).

[0005] The stacking device (15) of the car loader and the car loading system disclosed by the Chinese utility model patent CN 208516520 U has the following disadvantages: first, the stacking device (15) needs to return to the fixed position to receive the material after stacking a row of materials, which affects the loading efficiency; second, the width of the stacking device (15) is fixed and cannot adapt to carriages of different widths, and can only be applied to carriages of a specific width.

[0006] The Chinese invention patent application CN 112141728 A discloses a feeding device of a stacking machine, two left and right symmetrical feeding devices (1) are arranged on the stacking machine, when the left feeding device is stacking, the right feeding device is pre-arranging, and the stacking is alternately interacted, the loading efficiency is improved, but the feeding device (1) needs to return to the fixed position to receive the material each time, and the loading efficiency is not high.

When the carrier rack assembly 306 continuously descends, the material on the carrier rack assembly 306 is continuously discharged to the receiving drum assembly 402, and the height of the liftable continuous lifting mechanism 3 is adjustable, eliminating the return of the stacking platform 410 (described below) to the receiving process, and improving the loading efficiency.

[0101] In combination Figures 7 to 18 , according to the embodiment of the present application, the lifting and discharging and stacking mechanism 4 comprises a two-stage lifting assembly 401, a receiving drum assembly 402, a conveying drum assembly 405, a first linear box pushing module assembly 403, a material position adjusting assembly 404, a second linear box pushing module assembly 409, a chain back-and-forth box pushing assembly 407, a material blocking assembly 406, a platform width adjusting assembly 408 and a stacking platform 410.

[0102] According to the embodiment of the present application, the receiving drum assembly 402 connects the liftable continuous lifting mechanism 3 and is used to receive the box-shaped material 100 conveyed by the liftable continuous lifting mechanism 3, as Figure 6 shown.

[0106] According to an embodiment of the present invention, the first lifting seat 40106 is fixed on the traveling mechanism 1. Specifically, the first lifting seat 40106 is fixed on the frame assembly 101 of the traveling mechanism 1. The first lifting seat 40106 is configured to reciprocate relative to the column 40101 in the vertical direction.

[0107] The second lifting seat 40108 is connected to the palletizing platform 410 (described below), and the second lifting seat 40108 is configured to reciprocate in the vertical direction relative to the column 40101.

[0108] Furthermore, a first drive motor 40104 is fixed on the first lifting seat 40106.

[0109] The first drive motor 40104 drives the first lifting gear to rotate, and the first lifting rack 40102 responds to the reciprocating motion of the first lifting gear in the vertical direction, causing the column 40101 to reciprocate in the vertical direction. When the first lifting rack 40102 responds to the reciprocating motion of the first lifting gear in the vertical direction, the first sliding member 40105 reciprocates in the vertical direction on the first linear slide rail 40103.

[0110] The second lifting seat 40108 is fixed with a second drive motor 40110.

When the second lifting seat 40108 reciprocates vertically, the second sliding member 40107 reciprocates vertically on the second linear slide rail 40109.

[0112] When the first drive motor 40104 drives the first lifting gear to rotate on the first lifting rack 40102, the column 40101 rises and falls, realizing the first stage of lifting of the palletizing platform 410. When the second drive motor 40110 drives the first lifting gear to rotate on the second lifting rack 40111, the second lifting seat 40108 reciprocates in the vertical direction, realizing the second stage of lifting of the palletizing platform 410. The two-stage lifting configuration effectively increases the palletizing operation range.

[0113] like Figure 9 As shown, according to an embodiment of the present invention, the first linear pushbox module assembly 403 includes a first rod 40301, a mounting bracket 40302, and a first linear pushbox module 40303.

[0122] In a further embodiment, a bridge 41007 is arranged between the first support 41006 and the second support 41006'.

[0123] In combination Figures 10 to 14 , in the embodiment of the present application, the palletizing platform 410 is arranged with the chain back-and-forth pushing box assembly 407, the material blocking assembly 406, the platform width adjusting assembly 408 and the second linear pushing box module assembly 409.

[0124] The chain back-and-forth pushing box assembly 407 comprises a second pushing plate 40705, a first shaft 40704, a second shaft 40710, a back-and-forth chain 40701, a third driving motor 40706, a tensioning block 40707, a synchronous belt 40708, a synchronous pulley 40709 and a sprocket 40703.

The back-and-forth chain 40701 drives the second pushing plate 40705 to reciprocate along the horizontal direction in response to the third driving motor 40706, so as to push the box material 100 on the palletizing platform 410 to arrange into rows on both sides.

[0126] Specifically, sprockets 40703 are installed on both sides of the first shaft 40704 and the second shaft 40710, respectively. The sprockets 40703 are connected to the output shaft of the third drive motor 40706 via a timing belt 40708 and a timing pulley 40709. A bearing 40702 is installed between the timing pulley 40709 and the first shaft 40704 and the second shaft 40710. The timing belt 40708 is tensioned by a tensioning block 40707.

[0127] The material blocking assembly 406 includes a baffle 40601, a lever 40604, a hinge block 40605, a guide pin 40602, and a tension spring 40603.

A tension spring 40603 is connected to the end of the lever 40604 that is fixedly connected to the baffle 40601. A hinge block 40605 is hinged to the middle of the lever 40604, and the other end of the lever 40604 is a free end. A strip-shaped groove is formed in the baffle 40601, and a guide pin 40602 is embedded in the strip-shaped groove of the baffle 40601. The baffle 40601 can slide up and down relative to the guide pin 40602.

[0129] When the free end of lever 40604 is subjected to force, it moves downwards. Figure 11 As shown by arrow a), lever 40604 fixes one end of baffle 40601, causing baffle 40601 to lift. Figure 11 (As shown by arrow b), it blocks the box material 100 from moving forward and arranges the box material 100 neatly.

[0130] When the force on the free end of lever 40604 disappears, the tension spring 40603 pulls one end of the fixed baffle 40601 of lever 40604 downward, causing the baffle 40601 to reset. The force on the free end of lever 40604 is provided by the second linear push box module assembly 409, which will be described in detail below.

[0131] Combination Figure 10 , Figure 13 The platform width adjustment components 408 are distributed on both sides of the palletizing platform 410. The platform width adjustment components 408 include a third support 40801, a third linear slide rail 40802, and multiple first widening rods 40807.

[0132] Multiple first widening rods 40807 are vertically fixed on the third bracket 40801. The third linear slide rail 40802 is fixed on the third bracket 40801. The third sliding member 40803 is installed on the third linear slide rail 40802. The third sliding member 40803 is connected to the second linear push box module assembly 409.

[0134] Multiple second widening rods 41010 are provided on both sides of the platform frame 41001, multiple first widening rods 40807 are arranged intersecting with multiple second widening rods 41010, and a fourth sliding member 40805 is fixed on the second widening rods 41010.

[0135] According to an embodiment of the present invention, at least one end of a second widening rod 41010 is provided with a second electric cylinder 41005, and the output shaft of the second electric cylinder 41005 is connected to a third bracket 40801. Specifically, the third bracket 40801 has a mounting hole 40808, and the output shaft of the second electric cylinder 41005 is connected to the third bracket 40801 through the mounting hole 40808.

[0136] When the output shaft of the second electric cylinder 41005 extends or retracts, it pushes the platform width adjustment component 408 away from or towards the platform frame 41001, adjusting the width of the palletizing platform 410. This invention allows the platform width adjustment component 408 to move left and right according to the width of the carriage, adapting to carriages of different widths.

[0137] Furthermore, a plurality of first universal balls 40806 are arranged on the upper surface of the first widening rod 40807, and a plurality of second universal balls 41011 are arranged on the upper surface of the second widening rod 41010, so as to facilitate the arrangement of the box material 100 on both sides of the palletizing platform 410.

[0138] like Figure 14 As shown, according to an embodiment of the present invention, the second linear push box module assembly 409 includes a second rod 40901, a third rod 40903, a fourth bracket 40909, a fifth bracket 40907, and a second linear push box module 40910.

[0139] The second lever 40901 responds to the second linear pusher module 40910, pushing out the rows of boxed materials 100 arranged on the palletizing platform 410 and stacking them in the carriage.

[0140] Specifically, according to an embodiment of the present invention, the second linear pusher module 40910 is fixed on the platform frame 41001. A fourth bracket 40909 is provided on the second linear pusher module 40910, for example, the fourth bracket 40909 is mounted on the slider of the second linear pusher module 40910. A third electric cylinder 40902 is fixed on the fourth bracket 40909, and the output shaft of the third electric cylinder 40902 is fixed to the second rod 40901.

[0141] The second rod 40901 is fixed with a fifth linear slide rail 40904, and the fifth linear slide rail 40904 is installed with a fifth sliding piece 40908, and the fifth sliding piece 40908 is fixed on the third rod 40903. The fifth support 40907 is fixed with a sixth linear slide rail 40906, and the sixth linear slide rail 40906 is installed with a sixth sliding piece 40905, and the sixth sliding piece 40905 is fixed on the third rod 40903, and the fifth support 40907 is fixed with the third sliding piece 40803.

[0142] When the output shaft of the second electric cylinder 41005 is extended or retracted, the platform width adjusting assembly 408 is pushed away from or close to the platform frame 41001, and the third rod 40903 responds to the platform width adjusting assembly 408 and reciprocates with the fifth sliding piece 40908 on the fifth linear slide rail 40904 (as shown by arrow d), so as to realize the adaptation of the second rod 40901 to the carriage width. Figure 14

[0143] When the output shaft of the third electric cylinder 40902 is extended or retracted, the second rod 40901 is driven to move up and down, and the third rod 40903 responds to the second rod 40901 and reciprocates with the sixth sliding piece 40905 on the sixth linear slide rail 40906 (as shown by arrow c). Figure 14

[0144] Specifically, when the third electric cylinder 40902 drives the second rod 40901 to move downward, the second rod 40901 extrudes the free end of the lever 40604, so that the free end of the lever 40604 moves downward (as shown by arrow a). Figure 11

[0145] When the third electric cylinder 40902 drives the second rod 40901 to move upward, the force on the free end of the lever 40604 disappears, the pulling spring 40603 pulls the lever 40604 to move downward at one end of the fixed baffle 40601, drives the baffle 40601 to reset, and the baffle 40601 no longer blocks the box material 100. The second linear box pushing module 40910 drives the second rod 40901 to push the box material 100 arranged in a row on the stacking platform 410 out (as shown by arrow e), and the stacking is in the carriage. Figure 14

[0146] In combination with Figures 15 to 18 When the box material 100 in different postures is transferred to the receiving drum assembly 402 on the lifting and arranging and stacking mechanism 4 by the liftable and continuous lifting mechanism 3, the box material 100 is pushed to the conveying drum assembly 405 by the first linear box pushing module 403.

[0147] ​​​​The material position adjusting assembly 404 adjusts the position of the box-shaped material 100 on the conveying drum assembly 405, and the box-shaped material 100 is conveyed forward by the conveying drum assembly 405 to the material blocking assembly 406 arranged on the stacking platform 410 and then stopped on the chain reciprocating box pushing assembly 407.

[0148] The chain reciprocating box pushing assembly 407 pushes the box-shaped material 100 to the left and right and arranges the box-shaped material 100 in a row. The second straight-line box pushing module assembly 409 pushes the box-shaped material 100 arranged in a row to the carriage stacking position at one time, and completes the stacking task of the group of box-shaped materials 100.

[0149] In combination Figures 15 to 18 When the platform is higher than the carriage floor and the box-shaped material 100 is stacked near the carriage entrance, the lifting and stacking mechanism 4 may interfere with the platform when stacking the lowermost layer of box-shaped material 100. The linear bearing box unit 40504 fixed on the conveying drum assembly 405 and the guide shaft 41008 fixed on the stacking platform 410 are used to realize the vertical lifting of the conveying drum assembly 405 relative to the stacking platform 410 by sliding the linear bearing box unit 40504 relative to the guide shaft 41008 in the vertical direction. When the lifting and stacking mechanism 4 reaches the platform, the conveying drum assembly 405 is lifted a distance (such as shown in the figure) relative to the stacking platform 410 on the guide shaft 41008, avoiding the collision between the receiving drum assembly 402 and the platform, and solving the problem of loading the carriage.
