The first conveying device 11 can convey the pallet 2 by rotating a plurality of support rollers, and can support the pallet 2 when the support rollers do not rotate; the second conveying device 12 can convey by a belt, and the belt is rotatably arranged on a support platform, and the support platform supports the bottom of the upper half of the belt, and can move the pallet 2 onto the support rollers during the belt rotation. The first conveying device 11 and the second conveying device 12 are both prior art and will not be described in detail here.

[0043] The canned food palletizing device provided by the present invention is compared with the prior art. When the pallet 2 is in the palletizing position, the upper surface of the pallet 2 is in the same plane as the upper surface of the bottom support plate 4; the corrugated cardboard on the support plate 4 is pushed horizontally by the push plate structure 5, so that the corrugated cardboard can be pushed horizontally onto the pallet 2, so that the electromagnetic adsorption device can transport the arranged canned fruits to the corrugated cardboard on the pallet 2, and the canned fruits are placed on the corrugated cardboard on the pallet 2 in a power-off manner; after the first layer of canned fruits are placed on the pallet 2, the top of the first layer of canned fruits is at the same height as the top of the second layer of support plate 4. At this time, the push plate structure 5 on the second layer pushes the corrugated cardboard, so that the corrugated cardboard on the second layer of support plate 4 can be pushed horizontally to the top position of the first layer of canned fruits; and so on, until the pallet 2 is palletized to a preset height. Through the above-mentioned configuration of the present application, after the electromagnetic adsorption device leaves the position of the cardboard 2, the push plate structure 5 on the support plate 4 can push the corrugated cardboard horizontally to the designated position of the cardboard 2, thereby reducing the sense of urgency of the operator and being able to push the corrugated cardboard horizontally into place. It should be noted that the lid of the canned fruit is made of iron material, so it can be adsorbed by the electromagnetic adsorption device; the method of adsorbing and transporting the canned fruit by the electromagnetic adsorption device is a prior art and will not be described in detail here.

[0044] In some embodiments, Figures 1 to 10As shown, the palletizing equipment also includes a driving device 6 arranged on the support frame 3, and the driving device 6 has the freedom to slide along the height direction of the support frame 3; wherein the driving device 6 includes a sliding portion 61 that can be connected to each push plate structure 5, and the sliding portion 61 has the freedom to slide along the direction of the transverse channel.

[0045] Exemplarily, the driving device 6 also includes a horizontal support portion 62, and the sliding portion 61 is slidably matched with the horizontal support portion 62; a first screw 63 is rotatably provided on the horizontal support portion 62, and the sliding portion 61 is threadedly matched with the first screw 63; a first driving motor 64 is also provided on the horizontal support portion 62, and the output shaft of the first driving motor 64 is connected to one end of the first screw 63 to drive the first screw 63 to rotate. The first driving motor 64 drives the first screw 63 to rotate, so that the sliding portion 61 can slide horizontally, thereby facilitating the push plate structure 5 to move laterally.

[0046] Exemplarily, the side of the support frame 3 is rotatably provided with a second screw 65, and the second screw 65 is arranged in the height direction; the second screw 65 cooperates with the screw of the horizontal support part 62, and the top of the support frame 3 is connected with a second drive motor 66, and the output shaft of the second drive motor 66 is connected to the top of the second screw 65; the second drive motor 66 drives the second screw 65 to rotate, so that the horizontal support part 62 can slide in the height direction. The support frame 3 is also provided with a guide rod 67, which is arranged parallel to the second screw 65 and passes through the horizontal support part 62. By providing the guide rod 67, the sliding direction of the horizontal support part 62 can be guided, and the deflection of the horizontal support part 62 during the sliding process in the height direction can be reduced.

[0047] In some embodiments, Figures 1 to 10As shown, the push plate structure 5 includes a strip-shaped pushing portion 51 and a slide rail 52; the length direction of the strip-shaped pushing portion 51 is toward the transverse channel; the two sides of the strip-shaped pushing portion 51 are respectively provided with coaxially arranged rotating shafts 53, and each rotating shaft 53 has a slider 54 at one end away from the strip-shaped pushing portion 51, and the rotating shaft 53 and the slider 54 are rotatably matched; the slide rail 52 is arranged on the support plate 4; the slider 54 is slidably matched with the slide rail 52; wherein, the support plate 4 is provided with an avoidance groove 41 for the strip-shaped pushing portion 51 to rotate around the rotating shaft 53; the rotating shaft 53 is located at a position close to one end of the strip-shaped pushing portion 51, so that the two ends of the strip-shaped pushing portion 51 respectively form a proximal axis end 511 and a distal axis end 512; in the initial state, the proximal axis end 511 of the strip-shaped pushing portion 51 is in contact with the corrugated cardboard; the sliding portion 61 is provided with a rotating driving member 68, and the rotating shaft 53 of the rotating driving member 68 is detachably connected to the end of the rotating shaft 53. The rotating shaft 53 is fixed on the strip-shaped pushing portion 51, and can guide the slider 54 through the sliding cooperation between the slider 54 and the slide rail 52. The rotating driving member 68 can be a driving motor. The slide rail 52 has a positioning rod 55, which passes through the slider 54, and the slider 54 can slide on the positioning rod 55. Through the above arrangement, the rotation of the slider 54 can be limited, so that the slider 54 can only slide along the slide rail 52.

[0048] It should be noted that, in the initial position, the proximal end 511 of the strip pushing portion 51 faces the card board 2, and the strip pushing portion 51 moves to a position away from the card board 2, so it is convenient to place the corrugated cardboard on the support board 4; when the proximal end 511 of the strip pushing portion 51 pushes the corrugated cardboard horizontally out of the support board 4, the strip pushing portion 51 slides backward and drives the rotating shaft 53 to rotate 180 degrees through the rotating driving member 68, so that the distal end 512 of the strip pushing portion 51 faces the card board 2; at this time, the strip pushing portion 51 slides forward, and the distal end 512 of the strip pushing portion 51 can extend out of the support board 4 and push the corrugated cardboard into place.

[0049] In some embodiments, Figures 1 to 10 As shown, the side of the support frame 3 has a plurality of strip grooves 31, and the strip grooves 31 correspond to the rotating shaft 53 one by one; the strip groove 31 extends from one end of the rotating shaft 53, and the extended end of the rotating shaft 53 has a slot 531 that passes through from top to bottom; the rotating shaft 53 of the rotating drive member 68 has an insert block 681 that is plugged into the slot 531, and the insert block 681 is fixed on the rotating shaft 53 of the rotating drive member 68; the extended end of the rotating shaft 53 has a fixing structure for fixing the insert block 681.

[0050] It should be noted that when the sliding portion 61 moves upward to its position, the plug block 681 on the rotating drive member 68 is located in the slot 531 of the rotating shaft 53. At this time, the plug block 681 and the rotating shaft 53 are connected by a fixed structure, so that the plug block 681 and the rotating shaft 53 can be connected together; the lateral movement of the rotating drive member 68 can drive the rotating shaft 53 and the strip-shaped pushing portion 51 to move lateraly; and the rotating shaft 53 is driven to rotate 180 degrees by the rotating drive member 68, so that the strip-shaped pushing portion 51 can be rotated 180 degrees.

[0051] In some embodiments, Figures 1 to 10 As shown, the plug block 681 has a socket 682, and the extended end of the rotating shaft 53 has a through hole aligned with the socket 682; the fixing structure includes a first cylinder 56 and a first connecting plate 561, the cylinder body of the first cylinder 56 is fixed to the outer peripheral wall of the extended end of the rotating shaft 53 through the first connecting plate 561, and the first cylinder 56 and the first connecting plate 561 are both located on the outside of the support frame 3; the piston rod of the first cylinder 56 is aligned with the through hole at the extended end of the rotating shaft 53, and when the plug block 681 is plugged into and matched with the slot 531 of the rotating shaft 53, the piston rod of the first cylinder 56 is plugged into and matched with the socket 682 of the plug block 681 to fix the plug block 681 on the rotating shaft 53.

[0052] It should be noted that when the insert block 681 is plugged into the slot 531 on the rotating shaft 53, the insert block 681 can be fixed on the rotating shaft 53 by plugging the piston rod of the first cylinder 56 into the plug hole 682 of the insert block 681. The horizontal support portion 62 and the sliding portion 61 are both provided with an avoidance through groove 611 for avoiding the extended end of the rotating shaft 53, so that when the horizontal support portion 62 drives the sliding portion 61 to rise, interference between the extended end of the rotating shaft 53 and the sliding portion 61 and the horizontal support portion 62 can be avoided.

[0053] After the corrugated cardboard is pushed, the rotary drive member 68 drives the slider 54 to reset, and the piston rod of the first cylinder 56 is separated from the insertion hole 682 of the plug block 681. The horizontal support portion 62 can drive the rotary drive member 68 to slide upward, and finally the plug block 681 is plugged into the slot 531 on the upper layer of the rotating shaft 53. When the rotating shaft 53 is in the initial state, the slot 531 at the extended end of the rotating shaft 53 is vertically arranged.

[0054] In some embodiments, Figures 1 to 10 As shown, the slider 54 has a second cylinder 57 and a second connecting plate 571, and the cylinder body of the second cylinder 57 is fixed to the slider 54 through the second connecting plate 571; the part of the rotating shaft 53 located in the slider 54 has a positioning hole 532 aligned with the piston rod of the second cylinder 57, and the slider 54 has a through hole aligned with the positioning hole 532 and the piston rod of the second cylinder 57; when the piston rod of the second cylinder 57 is plugged into the positioning hole 532 of the rotating shaft 53, the rotation of the rotating shaft 53 around its axis can be limited.

[0055] It should be noted that, in the initial state and during the sliding process of the rotating shaft 53 following the slider 54, the piston rod of the second cylinder 57 is plugged into and matched with the positioning hole 532 of the rotating shaft 53 to limit the rotation of the rotating shaft 53; when the rotating drive member 68 drives the rotating shaft 53 to rotate, the piston rod of the second cylinder 57 is separated from the positioning hole 532; after the rotating shaft 53 rotates 180 degrees, the piston rod of the second cylinder 57 is plugged into and matched with the positioning hole 532 of the rotating shaft 53 again to limit the rotation of the rotating shaft 53.

[0056] In some embodiments, Figures 1 to 10 As shown, the distal end 512 of the strip-shaped pushing portion 51 has a slide groove 513, and an extension portion 58 is slidably provided in the slide groove 513 of the strip-shaped pushing portion 51; the inner side end of the extension portion 58 has an avoidance groove 41, and the avoidance groove 41 has an elastic member 581, and the two ends of the elastic member 581 are respectively connected to the extension portion 58 and the strip-shaped pushing portion 51; wherein, the inner side end of the extension portion 58 is provided with a pull rope 582, one end of the pull rope 582 is fixed to the inner side end of the extension portion 58, and the top of the strip-shaped pushing portion 51 near the opening of the slide groove 513 has a through hole for the other end of the pull rope 582 to pass through; the extended end of the pull rope 582 has a connecting component 59; when the distal end 512 of the strip-shaped pushing portion 51 pushes the corrugated cardboard, when the connecting component 59 moves to the end of the avoidance groove 41, the connecting component 59 can cooperate with the end of the avoidance groove 41 to limit the position of the connecting component 59.

[0057] It should be noted that the elastic member 581 is a spring, and the two ends of the spring are respectively connected to the extension part 58 and the strip-shaped pushing part 51; the spring can provide elastic force to the extension part 58, so that the extension part 58 is in a state of being retracted into the strip-shaped pushing part 51 in the absence of external force. When it is necessary to push the corrugated cardboard through the distal end 512 of the strip-shaped pushing part 51, when the connecting component 59 moves to the end of the avoidance groove 41, the connecting component 59 cooperates with the end of the avoidance groove 41, so that the connecting component 59 is in a stationary state; when the strip-shaped pushing part 51 continues to slide, the pull rope 582 will be pulled out of the strip-shaped pushing part 51, and the extension part 58 will extend out of the strip-shaped pushing part 51 under the pulling force of the pull rope 582, so that the pushing length can be extended, which is convenient for pushing the corrugated cardboard into place.

[0058] In some embodiments, Figures 1 to 10 As shown, the connecting component 59 is provided with a limit block 591, and the end of the avoidance groove 41 is provided with a limit groove 42 which is plugged into and matched with the limit block 591; when the limit block 591 is plugged into and matched with the limit groove 42, the rotation of the connecting component 59 can be limited; when the strip-shaped pushing portion 51 continues to slide, the extension portion 58 extends out of the strip-shaped pushing portion 51 under the action of the pull rope 582; the extension portion 58 is provided with a placement groove 583 for placing the pull rope 582.

[0059] It should be noted that the other end of the pull rope 582 is fixed on the connecting part 59, and the limit block 591 is fixed on the connecting part 59; in the initial state, the connecting part 59 is arranged upward; after the strip-shaped pushing part 51 rotates 180 degrees, the connecting part 59 is arranged downward and is located in the avoidance groove 41; when the connecting part 59 slides to the end position of the avoidance groove 41, the limit block 591 is plugged into the limit groove 42, and at this time, it can play a role in limiting the connecting part 59; when the strip-shaped pushing part 51 continues to slide, the connecting part 59 will not flip, so that the pull rope 582 is pulled out, and the extension part 58 extends out of the strip-shaped pushing part 51 under the action of the pull rope 582. When resetting, the spring in the strip-shaped pushing part 51 can pull the extension part 58 back into the strip-shaped pushing part 51, and at this time, the pull rope 582 will be retracted into the strip-shaped pushing part 51.

[0060] Exemplarily, the connecting component 59 is in surface contact with the top of the strip-shaped pushing portion 51, and under the action of tension, the connecting component 59 can be stably connected to the top position of the strip-shaped pushing portion 51, thereby ensuring a relatively stable state between the connecting component 59 and the strip-shaped pushing portion 51.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
