Detailed Implementation

[0018] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0021] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0022] Reference Figure 1 The automatic pallet packing machine of this invention includes a feeding device, a pallet handling device, a pallet 3, a foam pallet hopper, and a whole pallet handling device.

[0023] Among them, reference Figure 2The feeding device includes a feeding conveyor line 1 and a feeding channel. The feeding conveyor line 1 feeds the small round bottles 13 from the previous process into the feeding channel one by one and arranges them in a row. When a specified number is reached, the feeding conveyor line 1 stops, forming a queue.

[0024] The tray handling device includes a planar SCARA robot arm 2 (Selective Compliance Assembly Robot Arm, a robot arm used for assembly operations) and an equidistant material distribution mechanism 4 on it. Multiple first suction cups 30 installed on the equidistant material distribution mechanism 4 are used to transport the small round bottles 13 on the feed conveyor line 1 in a row to the tray handling device 3.

[0025] Reference Figure 2 The arranging device 3 includes a left arranging plate 21 and a right arranging plate 22, as well as a left sliding cylinder 23 that pushes the left arranging plate 21 and a right sliding cylinder 24 that pushes the right arranging plate 22. The left arranging plate 21 and the right arranging plate 22 are each provided with multiple recesses. The arrangement of the recesses on the left arranging plate 21 and the right arranging plate 22 is the same as the arrangement of the recesses on the foam tray 14. After the small round bottles 13 are placed into the recesses of the left arranging plate 21 or the right arranging plate 22, multiple small round bottles 13 can be arranged into a queue that meets the spacing requirements on the foam tray 14. The tray conveying device repeatedly places a queue of small round bottles 13 from the material channel into the tray device 3. When the left tray 21 is full of small round bottles 13, that is, when there are multiple queues of small round bottles 13 on the left tray 21, the left slide cylinder 23 pushes the left tray 21 backward to the waiting box position; when the right tray 22 is full of small round bottles 13, the right slide cylinder 2 pushes the right tray 22 backward to the waiting box position.

[0026] It is understood that in some other embodiments, the panel arrangement device 3 may also include only one panel and one slide cylinder.

[0027] Since the small round bottles 13 on the feed channel are arranged close together with a small gap between them, while the gap between the pits on the left plate 21 and the right plate 22 is relatively large, it is necessary to change the original gap between the rows of small round bottles 13 into the pit gap between the plates during the process of transporting the entire row of small round bottles 13 to the plate arrangement device 3.

[0028] Reference Figure 3The equidistant material distribution mechanism 4 includes a material distribution cylinder 25, a push plate 31, a fixed plate 32, a guide rail, multiple connecting rods 27, multiple sliders 26, multiple fixed pins 28, and multiple movable pins 29. The fixed plate 32 is fixedly connected to one end of the guide rail, the slider 26 is slidably connected to the guide rail, the push plate 31 is fixedly connected to one of the sliders 26, the movable pin 29 connects the ends of two connecting rods 27, the movable pin 29 connects the middle of two connecting rods 27, and the first suction cup 30 is set on the slider 26. The dispensing cylinder 25 pulls the push plate 31, driving the movement of a parallel four-bar linkage consisting of connecting rods 27, sliders 26, fixed pins 28, and movable pins 29. (Two connecting rods 27 intersect and are connected in the middle by a fixed pin 28 to form an X-shaped structure. The X-shaped structure can rotate around the fixed pin 28. Except for one fixed pin 28 connected to the fixed plate 32, the other fixed pins 28 are connected to a corresponding slider 26. The ends of the two X-shaped structures are connected by movable pins 29.) Each slider 26 can achieve equidistant synchronous extension and retraction relative to the origin position (where the fixed plate 32 remains stationary). Theoretically, provided the stroke and pulling force of the dispensing cylinder 25 are sufficient, the push plate 31 can be connected to any slider 26. That is, the equidistant dispensing mechanism 4 has a first state and a second state. In the first state, the distance between two adjacent sliders 26 decreases, making the distance between two adjacent first suction cups 30 smaller and basically the same as the distance between them and the small round bottles 13 at the top of the material channel, facilitating the first suction cup 30 to simultaneously pick up a queue of small round bottles 13. In the second state, the distance between two adjacent sliders 26 increases, making the distance between two adjacent first suction cups 30 larger, and basically the same as the distance between the pits on the left plate 21 and the right plate 22, so that a row of small round bottles 13 can be easily placed onto the left plate 21 or the right plate 22 as a whole.

[0029] It should be noted that in some other embodiments, an equidistant mechanism can also be set on the feeding device. The equidistant mechanism separates the adjacent small round bottles 13 by a certain distance at the material channel. After the plate-laying and conveying device transports the small round bottles 13 separated by the distance to the plate-laying device 3, they can be directly placed into the recess of the left plate 21 or the right plate 22.

[0030] Reference Figure 1 The whole-plate handling device includes a six-axis robot 5 and a whole-plate transfer device 6. The whole-plate transfer device 6 is a device with multiple rows of second suction cups 61 installed on a flat plate and driven by the six-axis robot 5. The whole-plate transfer device 6 installed on the six-axis robot 5 will pick up all the small round bottles 13 on the left row plate 21 or the right row plate 22 that are in the position to be placed into the box at once, and then the six-axis robot 5 will transport them into the box for placement.

[0031] Reference Figure 1 There are two foam pallet silos: a left foam pallet silo (7) and a right foam pallet silo (8). These silos are stackable warehouses for foam pallets (14). (Refer to...) Figure 4 The foam pallet hopper includes a hopper body, a servo module 33, a lifting platform plate 34, a scraper cylinder 37, and a scraper 38. The hopper body has an inner cavity for accommodating the foam pallet 14 and an opening at the top of the hopper body, which connects to the inner cavity. The lifting platform plate 34 is located at the bottom of the hopper body and supports the foam pallet 14. The servo module 33 drives the lifting platform plate 34 to move up and down. The scraper 38 is located at the opening. When the second suction cup 61, which is connected to the whole-pallet transfer device 6 of the six-axis robot 5, picks up the foam pallet 14 and lifts it upward, the scraper cylinder 37 pushes the scraper 38 to extend. The scraper 38 can effectively separate other foam pallets 14 stacked below. After one foam pallet is retrieved, the whole stack of foam pallets 14 moves downward back to the lowest position under the drive of the servo module 33 (this action is to allow the foam pallets 14 that may have been lifted during the retrieval process to fall back to the top of the pallet stack).

[0032] Reference Figure 4 The foam pallet hopper also includes a spring 35 and a foam tray support plate 36. The foam tray support plate 36 is located above the lifting platform plate. The upper end of the spring 35 is connected to the foam tray support plate 36, and the lower end is connected to the lifting platform plate 34. The foam pallet 14 is placed on the foam tray support plate 36. The spring 35 and the foam tray support plate 36 play a buffering role when the six-axis robot 5 picks up the pallet. That is, when the six-axis robot 5 presses down on the foam pallet 14, causing the second suction cup 61 installed on the whole board transfer device 6 to suck up the foam pallet 14, the foam pallet 14 is easily deformed and damaged by the force. By setting the spring 35 and the foam tray support plate 36, the foam pallet 14 can deform when subjected to downward pressure, buffering the pressure and preventing damage to the foam pallet 14.

[0033] Reference Figure 4 The foam pallet hopper is also equipped with a photoelectric switch 39 near the opening. Each time the pallet rises from the lowest point, it quickly moves to this preparatory position. After the photoelectric switch 39 detects that it is in position, the rising speed slows down until it hits the second suction cup 61 of the whole board transplanting device 6 and is completely sucked in (the negative pressure on the suction cup reaches the switch setting value) and then stops rising.

[0034] Reference Figure 1 The automatic packing and boxing machine of this embodiment also includes an empty box storage line 9, which is used to temporarily store empty boxes for fully automatic operation, reducing the number of times empty boxes are manually placed, and can also be connected to a box opening device at the front end.

[0035] Reference Figure 1 The automatic packing and boxing machine of this embodiment of the invention also includes a boxing conveyor line 10, which is used to transport empty boxes to the boxing station located in the middle, and then to pack and transport foam trays 14 and small round bottles 13.

[0036] Reference Figure 6The packing conveyor line includes a stop cylinder 51, two clamping cylinders 47, two clamping plates 48, a box-blocking cylinder 49, and a box-blocking plate 50. The two clamping plates 48 are located on both sides of the box 15. Each clamping cylinder 47 is connected to a clamping plate 48. The stop cylinder 51 extends to allow the empty box to reach the packing station. After it reaches the station, the clamping cylinders 47 on both sides drive the clamping plates 48 to extend and fix the position of the empty box. The box-blocking cylinders 49 on both sides push out the box-blocking plate 50 to block the subsequent empty boxes.

[0037] Reference Figure 1 The automatic packing and boxing machine of this invention also includes a box opening opening device 11, which is used to open the box opening outward at a certain angle to prevent the box opening from being scratched and deformed during the packing process.

[0038] Reference Figure 5 The box opening device 11 includes an opening cylinder 45, a rotating shaft push plate 44, a rotating shaft 40, an upper and lower adjustment plate 41, a left support box plate 42, and a right support box plate 43. The rotating shaft push plate 44 is fixedly connected to one end of the rotating shaft 40, the upper and lower adjustment plate 41 is fixedly connected to the rotating shaft 40, and the left support box plate 42 and the right support box plate 43 are connected to the upper and lower adjustment plate 41. The opening cylinder 45 pushes and pulls the rotating shaft push plate 44, thereby driving the rotating shaft 40 to rotate. The upper and lower adjustment plate 41 installed on the rotating shaft 40, together with the left support box plate 42 and the right support box plate 43, flips down, thereby opening the box opening.

[0039] Reference Figure 1 The automatic packing and boxing machine of this embodiment also includes a finished product storage line 12, which is used to temporarily store the full boxes 15, waiting for them to enter the next process. The running route of the boxes 15 is as follows: from the empty box storage line 9, they are transported to the boxing conveyor line 10, and after being packed, they arrive at the finished product storage line 12.

[0040] To better understand the technical solution of the automatic plating and packing machine according to the embodiments of the present invention, the operation process of the automatic plating and packing machine according to the embodiments of the present invention will be described in detail below.

[0041] Small round bottles 13 are continuously fed from the previous process via the feeding conveyor line 1 and arranged in a row. Once a specified quantity is reached, the feeding conveyor line 1 stops, and the planar SCARA robot arm 2 descends to pick up the bottles. At this time, the equidistant dispensing mechanism 4 installed at the lower part of the planar SCARA robot arm 2 has its dispensing cylinder 25 extended, and the first suction cups 30 in a row are in a small-interval state. After reaching the picking position, the first suction cups 30 use vacuum to pick up the row of small round bottles 13 on the feeding conveyor line 1.

[0042] After the planar SCARA robot arm 2 rises, it moves to the position above the corresponding row on the left shelf 21. The dispensing cylinder 25 retracts, driving the parallel four-bar linkage composed of connecting rod 27, slider 26, fixed pin 28, and movable pin 29 to move. This switches the first suction cup 30 of the first row to a large-pitch state (the same as the spacing between the slots on the shelf). Then, the planar SCARA robot arm 2 descends to place the small bottle into the slot. After completing the dispensing action, the planar SCARA robot arm 2 returns to above the feeding conveyor line 1, the dispensing cylinder 25 extends, and the first suction cup 30 of the first row switches back to a small-pitch state, ready to receive the next row of small round bottles 13. This process is repeated.

[0043] When the left panel 21 is full of small round bottles 13, the left slide cylinder 23 pushes them backward to the position to be transported. At this time, the planar SCARA robot 2 automatically places the subsequent incoming materials into the right panel 22 (the two alternately put materials in and push them out).

[0044] While performing the above-mentioned board arrangement work, the six-axis robot 5 on the other side turns right to the left foam pallet hopper 7 or the right foam pallet hopper 8 (depending on which hopper has a pallet) to pick up a foam pallet 14. The whole board transfer device 6 installed at the bottom of the six-axis robot 5 first stops at the top of the foam pallet hopper to pick up the material. The second suction cup 61 in the whole board transfer device 6 maintains a vacuum suction state.

[0045] The servo module 33 drives the pallet stack to move upward rapidly. When it reaches the position of the photoelectric switch 39, the upward movement slows down. The top foam pallet 14 of the pallet stack is sent to the second suction cup 61 of the whole board transfer device 6 and is partially sucked by the second suction cup 61. At the same time, due to the combined action of the lifting platform plate 34, spring 35 and foam tray support plate 36, a greater upward force is applied until the foam pallet 14 is sucked by all the second suction cups 61 on the whole board transfer device 6. Then, the negative pressure switch connected to the second suction cups 61 reaches the set value, and the lifting platform plate 34 stops rising.

[0046] The four scraper cylinders 37 on the foam pallet hopper simultaneously push out the scrapers 38, inserting them between the sucked-up foam pallet 14 and the next foam pallet 14. Driven by the six-axis robot 5, the sucked-up foam pallet 14 is lifted, thus achieving the separation operation of the nested foam pallets 14. Next, the six-axis robot 5 places the sucked-up foam pallet 14 into the box 15. The scrapers 38 on the foam pallet hopper retract, and the servo module 33 drives the pallet stack to quickly return to the bottom. The loose, floating foam pallets 14 on the upper layer fall back into the hopper, facilitating the next positioning and picking.

[0047] After the foam tray 14 is placed, the six-axis robot 5 and the whole-board transfer device 6 installed below it turn to the left and pick up all the small round bottles 13 on the left row plate 21 at once, and place them on the corresponding layer of the box 15 of the packing conveyor line 10.

[0048] Reference Figure 7 and Figure 8 As shown, the foam tray 14 has a series of tapered circular indentations, wider at the top and narrower at the bottom. The center distance between each indentation is accurate. However, because the foam tray 14 is made of flexible material and is easily deformed, the distance from the four edges to the center point of the indentation at the edge deviates significantly after the cutting process. When the foam tray 14 is inserted into the box 15, the four edges contact the perimeter of the box 15. Due to the deviation in the inner width of the box 15, the center point of the indentation on the foam tray 14 will deviate from the preset center point when the six-axis robot 5 is unloading the material. Sometimes, when the small round bottle 13 is placed directly, the bottle mouth may fall exactly on the tapered slope of the indentation, resulting in misalignment and the bottle tipping over. Because the foam tray 14 is made of soft and easily deformable material, the following method is required for placement: After the six-axis robot 5 is placed into the box 15 at the predetermined layer height, while holding the small round bottle 13, the robotic arm of the six-axis robot 5 moves back and forth and left and right twice. That is, when the six-axis robot 5 places the small round bottle 13 on the foam tray 14, the second suction cup 61 is not released. The entire tray is moved back and forth and left and right with small amplitude twice, and then the vacuum is released. The purpose is to use the outer circle of the bottle mouth of the small round bottle 13 to drag back and forth to fit the tapered slope on the recess of the foam tray 14, so as to achieve the self-alignment function. When the second suction cup 61 is released, the bottle mouth of the small round bottle 13 is on the bottom plane of the foam tray 14 to ensure that the entire layer is placed flat, that is, to ensure that the small round bottle 13 is accurately placed in the recess of the foam tray 14.

[0049] Repeat this process, placing a foam tray 14 before each small round bottle 13 is taken out, until the box is full.

[0050] After a box is filled, the flipping cylinder 45 in the box opening device 11 drives the rotating shaft 40 to rotate by pushing the rotating shaft push plate 44, causing the left support plate 42 and the right support plate 43 to flip up to a horizontal position. The clamping plates 48 on both sides of the boxing conveyor line 10 retract, the stop cylinder 51 retracts, and the boxing conveyor line 10 starts to send the full box to the finished product storage line 12.

[0051] After a full box leaves the packing station, the stop cylinder 51 extends, and the side box-blocking cylinders 49 retract the box-blocking plates 50. The empty box storage line 9 starts, and empty boxes begin to be fed in. After an empty box arrives at the packing station, the side clamping cylinders 47 push out the clamping plates 48 to fix the position of the empty box, and the side box-blocking cylinders 49 push out the box-blocking plates 50 to stop subsequent empty boxes. The empty box storage line 9 stops. The left box-blocking plate 42 and the right box-blocking plate 43 in the box opening device 11 flip down to the box-blocking position, and the next box begins to be loaded.

[0052] This invention also provides a process method for an automatic packing and boxing machine.

[0053] Step 1: The feeding device feeds the small round bottles 13 one by one into the feeding channel to form a row. When the specified number is reached, the feeding conveyor line 1 stops, forming a queue.

[0054] Step 2: The stacking and conveying device sends the small round bottles 13 arranged in a row to the stacking device 3 together. During the conveying process, the spacing between the small round bottles 13 is changed so that the spacing between the small round bottles 13 is the same as the spacing between the stacking slots of the stacking device 3.

[0055] Step 3: The whole-board handling device takes out a foam pallet 14 from the foam pallet 14 hopper. During the taking out process, the servo module 33 drives the pallet stack to move upward quickly. When it reaches the position of the photoelectric switch 39, it stops moving upward slowly. The top foam pallet 14 of the pallet stack is sucked by the second suction cup 61. The scraper 38 cylinder 37 pushes the scraper 38 out and inserts it between the sucked foam pallet 14 and the next foam pallet 14. Driven by the six-axis robot 5, the sucked foam pallet 14 is lifted and placed into the box 15. The scraper 38 cylinder 37 retracts the scraper 38, and the servo module 33 drives the pallet stack to quickly return to the bottom.

[0056] Step 4: The whole board transport device picks up the small round bottles 13 arranged in a board from the board arrangement device 3 in one go and places them into the box 15 containing the foam tray 14.
