[0042] Reference Figures 1 - 8 , this embodiment provides an automatic stacking device for dry ice packing. This automatic stacking device is an automated equipment applicable to the packing production line process of dry ice bags, aiming to improve the operation efficiency and reduce the need for manual handling and stacking.

[0043] Such as Figure 1 , this automatic stacking device is successively provided along the conveying route with:

[0044] The feeding conveyor device 1 is responsible for transporting dry ice bags to the feeding device 2.

[0045] The feeding device 2 is composed of a chain conveyor belt 21 and a pushing member 22. Two groups of feeding members 23 are provided on the chain conveyor belt 21. The feeding member 23 is used to arrange and place multiple dry ice bags, and the pushing member 22 is used to push the neatly arranged multiple dry ice bags on the feeding member 23 onto the feeding device 3.

[0046] The feeding device 3 includes a transporting member 31, a feeding member 32 and a discharging member 33. The neatly arranged multiple dry ice bags form a dry ice bag group, and the automatic transportation and placement of the dry ice bag group are realized by the cooperation of the transporting member 31, the feeding member 32 and the discharging member 33.

[0047] This automatic stacking device is a device for dry ice packing. A gripping manipulator and a box for placing dry ice bags are configured at the output end of the feeding device 3. The gripping manipulator grabs the neatly stacked dry ice bag group placed on the discharging member 33 for packing operation.

[0048] The specific structure is as follows:

[0049] Such as Figure 2 , the feeding device 2 is provided with a chain conveyor belt 21, and a pushing member 22 is provided above the chain conveyor belt 21. The chain conveyor belt 21 is set as a return conveyor belt, which is divided into an upper conveyor belt 211 and a lower conveyor belt 212. During the transportation of the chain conveyor belt 21, one group of feeding members 23 is on the upper conveyor belt 211 and transports dry ice bags for the transportation of the feeding device 3, and one group of feeding members 23 is on the lower conveyor belt 212 waiting for the feeding of dry ice bags. Through the circular setting of the chain conveyor belt 21, the waiting time is reduced and the transportation efficiency is improved.

[0050] As Figure 4 shown, the material distribution member 23 is composed of a plurality of paddle plates 231 arranged at intervals. The intervals between the paddle plates 231 are used to place a bag of dry ice bags. The chain conveyor 21 includes an input end and an output end. The input end is connected to the feeding conveyor device. At the input end, the material distribution member 23 is gradually transported from the lower conveyor belt 212 to the upper conveyor belt 211. The output end is arranged at the rear side of the pusher member 22. After the pusher member 22 feeds the material, at the input end, the material distribution member 23 is gradually transported from the upper conveyor belt 211 to the lower conveyor belt 212.

[0051] As Figure 3 shown, the feeding and conveying device 1 and the material distribution member 23 are coordinated in the following way: when the material distribution member 23 is gradually transported to the upper conveyor belt 211 at the input end, the paddle plates 231 of the material distribution member 23 move upward one by one. The feeding and conveying device 1 transports bags of dry ice bags one by one. When the first paddle plate 231 of the material distribution member 23 is transported to the upper conveyor belt 211, the interval between the second paddle plate 231 and the first paddle plate 231 faces the output end of the feeding and conveying device 1, and receives the first bag of dry ice bags transported by the feeding and conveying device 1. With the conveyance of the chain conveyor 21 and the transportation coordination of the feeding and conveying device 1, bags of dry ice bags are placed one by one in the intervals of several paddle plates 231 in sequence. And this interval allows one bag of dry ice bags to be placed, and does not exceed one bag of dry ice bags.

[0052] In order to facilitate the placement of bags of dry ice bags into one interval after another, in this embodiment, a photoelectric sensor 24 is provided at the input end of the chain conveyor 21. Sensor mounting seats 25 are arranged on both sides of the input end of the chain conveyor 21, and the photoelectric sensor 24 is arranged on the sensor mounting seats 25. The photoelectric sensor 24 is used to sense whether there is a dry ice bag stored in the interval. The photoelectric sensor 24 is connected to the control system of the device, and controls the conveyance speeds of the chain conveyor 21 and the feeding and conveying device 1 through the control system of the device, so as to be able to place them one by one corresponding to the intervals.

[0053] As Figure 5 shown, a pressing member 26 is arranged between the material distribution device 2 and the feeding device 3, which is used to press the dry ice bag group inward to make it compact, so that it will not be too loose when being grabbed by the subsequent grasping manipulator, resulting in the inability to be grabbed. The pressing member 26 includes a pressing base 361 and pressing blocks 262 arranged on both sides of the pressing base 361. The pressing blocks 262 on both sides are driven by a pressing cylinder 263. The pressing base 361 is arranged on one side of the upper conveyor belt 211, and a conveying member 31 is connected to the side of the pressing base 361 opposite to the upper conveyor belt 211.

[0054] When the material distributing part 23 is filled with dry ice bags and transported to the position where the pressing base 361 is located, the pushing part 22 pushes the dry ice bag group onto the pressing base 361. The pressing base 361 is equipped with a material sensor. After sensing the dry ice bag group, it drives the pressing cylinder 263, and the pressing block 262 compacts the dry ice bag group from both sides inward. Through the compaction and stabilization of the pressing part 26, the neatness and safety of the dry ice bag group during transportation are ensured.

[0055] As Figure 6 , the pushing part 22 includes a pushing slide rail base 221, a first pushing cylinder 222 and a second pushing cylinder 223 slidably installed on the pushing slide rail base 221. A first pushing plate 224 is arranged at the driving end of the first pushing air rod, and a second pushing plate 226 is arranged at the driving end of the second pushing cylinder 223. The first pushing plate 224 is used to push the dry ice bag group in the material distributing part 23 onto the pressing base 361, and the second pushing plate 226 is used to push the dry ice bag group on the pressing base 361 onto the transporting part 31 for the next transportation. The first pushing plate 224 and the second pushing plate 226 are pushed simultaneously to complete the processes of discharging and loading materials on the pressing base 361 at the same time, and achieve cyclic compaction and cyclic transportation.

[0056] The driving of the pushing part 22 is that the first pushing cylinder 222 is provided with a first slider 227, the second pushing cylinder 223 is provided with a second slider 228, a slide rail 229 is arranged on the pushing slide rail base 221, the first slider 227 and the second slider 228 are slidably installed on the slide rail 229, and the first slider 227 is driven by a first cylinder, and the second slider 228 is driven by a second cylinder. The slide rail 229 and the sliders realize the left and right movement of the first pushing plate 224 and the second pushing plate 226, and realize the pushing of the dry ice bag group. The first pushing cylinder 222 and the second pushing cylinder 223 are used to realize the up and down movement of the first pushing plate 224, and realize the contact or separation from the dry ice bag group.

[0057] In order to cooperate with the structure of the spaced deflector plates 231 to better obtain the dry ice bags in the intervals, a number of inserting plates 225 are arranged on the first pushing plate 224, and the inserting plates are also spaced, which is convenient for inserting one by one into the intervals of the deflector plates 231 to push the dry ice bags. The pushing part 22 achieves precise pushing to ensure the accurate placement of the dry ice bag group.

[0058] As Figures 7 - 8, the feeding device 3 is provided with a transport member 31, which includes a transport slide rail base 311 and a moving seat 312 slidably mounted on the transport slide rail base 311. The movement of the moving seat 312 on the transport slide rail base 311 has a first position and a second position. When the moving seat 312 slides to the first position, the moving seat 312 moves to one side of the pressing base 361 to receive the dry ice bag group pushed by the second push plate 226; when the moving seat 312 slides to the second position, the moving seat 312 is placed between the feeding member 32 and the discharging member 33. Laser sensors 313 are provided on both sides of the track of the transport slide rail base 311 to sense the position of the moving seat 312. Through the flexible movement of the moving seat 312 and in cooperation with the laser sensors 313, accurate control of the position is achieved.

[0059] The feeding member 32 and the discharging member 33 are oppositely arranged on both sides of the transport slide rail base 311. The feeding member 32 includes a push plate 321 and a feeding air cylinder 322 for driving the push plate 321. The discharging member 33 is provided with a discharging plate 331. When the moving seat 312 moves the dry ice bag group to the second position, the push block pushes the dry ice bag group towards the discharging plate 331 for transportation under the drive of the feeding air cylinder 322. The coordinated operation of the feeding member 32 and the discharging member 33 realizes the automatic handling and stacking of the dry ice bag group.

[0060] The dry ice bag group is placed at the discharging plate 331 and waits for the grabbing manipulator to grab and complete the boxing operation. To facilitate the discharging of the discharging member 33 and the grabbing of the waiting-to-be-grabbed manipulator, the discharging member 33 is provided with a flipping mechanism and four groups of discharging plates 331 arranged at intervals along the circumferential direction on the flipping mechanism. As the flipping mechanism rotates, one group of discharging plates 331 will be docked with the moving seat 312, and then receive the dry ice bag group pushed by the push plate 321.

[0061] U-shaped baffles 333 are provided on both sides of the discharging plate 331 for clamping on the left and right to clamp the dry ice bag group. And the U-shaped opening of the U-shaped baffle 333 is used to facilitate the grabbing manipulator to obtain the dry ice bag group. Let the docking of the discharging plate 331 with the dry ice bag group and the moving seat 312 be a position. At this position, the U-shaped opening of the U-shaped baffle 333 faces the moving seat 312. After the discharging plate 331 receives the dry ice bag group, it is flipped backward once by the flipping mechanism to be a second position, and the grabbing manipulator obtains it at this position. When the discharging plate 331 is in the second position, the U-shaped opening of the U-shaped baffle 333 faces vertically.

[0062] The above is only the preferred specific embodiment of the present invention, but the design concept of the present invention is not limited to this. Any person skilled in the art within the technical scope disclosed by the present invention who makes non-substantive modifications to the present invention using this concept shall fall within the scope of infringement of the protection of the present invention.
