[0036] refer to Figures 1 to 6 A pallet conveying device according to an embodiment of the present invention is described.

[0037] like Figures 1 to 6 As shown, the pallet conveying device includes a frame 100; a conveying channel 200, which is arranged on the frame 100 and is used to convey a single pallet 10; a first clamping mechanism 300, which is arranged on the frame 100 and is used to release the pallet 10 located at the bottom onto the conveying channel 200; a second clamping mechanism 400, which is arranged on the frame 100 and is used to lift the foam cotton 20 to form a make way channel, which is used to enable the pallet 10 to be transferred smoothly; a first transfer mechanism 500, which is arranged on the frame 100 and is used to place the foam cotton 20 on the pallet 10; the first clamping mechanism 300, the second clamping mechanism 400 and the first transfer mechanism 500 are sequentially arranged on the conveying channel 200, and the pallet 10 passes through the make way channel to reach the output end of the conveying channel 200.

[0038] like Figures 1 to 3 As shown, the conveying channel 200 extends in the front-to-back direction, the front end of the conveying channel 200 is the entry and exit end, and the rear end is the output end. The first clamping mechanism 300 is located at the input end of the conveying channel 200, the first transfer mechanism 500 is located above the conveying channel 200, and the second clamping mechanism 400 is located between the input end of the conveying channel 200 and the output end of the conveying channel 200.

The pallets 10 are stacked vertically and placed on the input end of the conveying channel 200, and the foam cotton 20 is stacked vertically and placed above the conveying channel 200 via the second clamping mechanism 400. The first clamping mechanism 300 retains the pallet 10 at the bottom layer on the conveying channel 200 and lifts all the pallets 10 above it. Under the action of the conveying channel 200, the pallet 10 at the bottom layer passes through the give way channel to reach the output end of the conveying channel 200. The first transfer mechanism 500 places the foam cotton 20 at the top on the pallet 10, thereby completing the entire process of automatic laying of the foam cotton 20, which not only improves the stacking efficiency and the stability of the production line, but also reduces the demand for human resources and reduces labor costs.

[0039] It should be noted that the foam cotton 20 is stacked in the vertical direction and placed on the output end of the conveying channel 200. Under the action of the conveying channel 200, the foam cotton 20 reaches the position corresponding to the second clamping mechanism 400. The second clamping mechanism 400 lifts all the foam cotton 20 upward. At this time, a make way channel is formed between the vertically stacked foam cotton 20 and the conveying channel 200 below, thereby completing the loading of the foam cotton 20.

[0040] Specifically, the conveying channel 200 is a roller conveyor.

[0041] In some specific embodiments of the present invention, a second transfer mechanism 600 is further included. The second transfer mechanism 600 is disposed at the output end of the conveying channel 200 and is used to transport the pallet 10 in a direction perpendicular to the conveying channel 200. Figure 1 As shown, the second transfer mechanism 600 is located at the output end of the conveying channel 200. When the pallet 10 passes through the yield channel and reaches the output end of the conveying channel 200, the second transfer mechanism 600 transfers the pallet 10 to the palletizing stations at both ends to provide palletizing for subsequent products.

[0047] like Figure 1 and Figure 4As shown, the second lifting member 411 is disposed on the frame 100, and the second telescopic member 412 is disposed at the lower end of the second lifting member 411. Specifically, the second lifting member 411 is a cylinder with downward output, and a second cross bar 4111 is disposed at the output end of the cylinder along the front-to-back direction. The second telescopic member 412 includes a second connecting member 4121 and two second connecting rods 4122, which are symmetrically disposed at the front and rear ends of the second connecting member 4121. The second connecting member 4121 and the two second connecting rods 4122 all extend along the front-to-back direction and are located on the same straight line. The second connecting member 4121 is rotatably disposed in the middle of the second cross bar 4111, and each second connecting rod 4122 is rotatably connected to the second connecting member 4121. The second support member 413 includes two second wing plates 4131, each second connecting rod 4122 is correspondingly provided with a second wing plate 4131, and the second wing plates 4131 are all located at the end of the second connecting rod 4122 opposite to the second connecting member 4121.

The two second connecting rods 4122 arranged in the front and rear move toward each other as the second connecting piece 4121 rotates. At the same time, the second connecting rod 4122 has a traction effect on the correspondingly connected second wing plate 4131. The second wing plate 4131 rotates toward the direction close to the pallet 10 and penetrates into the bottom of the foam cotton 20. The cylinder lifts the second cross bar 4111 upward, and all the second wing plates 4131 lift the foam cotton 20 upward under the action of the cylinder, and leave a gap to form a make way channel.

Figure 1 and Figure 5As shown, when the pallet 10 passes through the give way channel and reaches the output end of the conveying channel 200, the displacement component 510 drives the lifting component 520 forward to directly above the foam 20, and the lifting component 520 drives the grabbing component 530 to descend to grab the foam 20 located at the top. The displacement component 510 drives the lifting component 520 backward to directly above the pallet 10 located at the output end of the conveying channel 200, and the lifting component 520 drives the grabbing component 530 to descend, so that the grabbing component 530 releases the foam 20 onto the pallet 10, thereby completing the laying of the foam 20.

[0049] In this specific embodiment, the displacement component 510 is a chain conveyor, the lifting component 520 is a chain elevator, and the grabbing component 530 is a suction cup grabber.

[0050] In some specific embodiments of the present invention, the second transfer mechanism 600 includes two third clamping assemblies 610, which are symmetrically arranged on opposite sides of the conveying channel 200, and the two third clamping assemblies 610 are used to lift the pallet 10 located at the output end of the conveying channel 200.

[0051] In some specific embodiments of the present invention, the third clamping assembly 610 includes: a displacement member 611, which is arranged on the frame 100; a third lifting member 612, which is connected to the displacement member 611, and the displacement member 611 is used to drive the third lifting member 612 to move in a direction perpendicular to the conveying channel 200; a third support member 613, which is connected to the third lifting member 612, and the third lifting member 612 is used to drive the third support member 613 to rise and fall, so as to lift and lower the pallet 10 located at the output end of the conveying channel 200.

The cylinder outputs downward, and its output end is connected to the support rod 6131. Therefore, when the foam surface is laid, the cylinder drives the support rod 6131 to move downward, so that the horizontal height of the support plate 6132 is lower than the horizontal panel of the pallet 10, and the two sliders 6112 move toward the direction close to the pallet 10, so that the support plates 6132 on the support rods 6131 on the left and right sides of the pallet 10 penetrate into the bottom of the pallet 10, and the cylinder lifts the support rod 6131 upward. All the support plates 6132 lift the pallet 10 upward under the action of the cylinder, and the two sliders 6112 are moved synchronously along the extension direction of the slide rail 6111 to realize the transfer of the pallet 10.

[0053] In some specific embodiments of the present invention, limit members 210 are provided at opposite ends of the conveying channel 200 . All the limit members 210 extend along the length direction of the conveying channel 200 . The limit members 210 are used to limit the conveying direction of the pallet 10 .

Under the action of the conveying channel 200, the foam cotton 20 reaches the position corresponding to the second clamping mechanism 400. The cylinder drives the second cross bar 4111 to move downward, so that the horizontal height of the second wing plate 4131 is level with the bottom of the bottom layer of foam cotton 20. The second connecting member 4121 rotates 90°, and the two second connecting rods 4122 arranged in the front and back move toward each other as the second connecting member 4121 rotates. At the same time, the second connecting rod 4122 has a traction effect on the correspondingly connected second wing plate 4131. The second wing plate 4131 rotates toward the direction close to the pallet 10 and penetrates into the bottom of the foam cotton 20, lifting the second cross bar 4111 upward. All the second wing plates 4131 lift the foam cotton 20 upward and leave a gap to form a make way channel. The pallets 10 are stacked vertically and placed on the input end of the conveying channel 200, the first cross bar 3111 is moved downward so that the horizontal height of the first wing plate 3131 is lower than the horizontal panel of the penultimate pallet 10, the first connecting member 3121 is rotated 90°, and the two first connecting rods 3122 arranged in the front and rear move toward each other as the first connecting member 3121 rotates. At the same time, the first connecting rod 3122 has a traction effect on the correspondingly connected first wing plates 3131, and the first wing plates 3131 are rotated toward the direction of approaching the pallet 10 and penetrate into the bottom of the pallet 10, lifting the first cross bar 3111 upward. All the first wing plates 3131 lift the pallet 10 upward and leave the pallet 10 at the bottom on the conveying channel 200. The pallet 10 at the bottom passes through the yield channel and reaches the output end of the conveying channel 200 under the action of the conveying channel 200. The lifting assembly 520 drives the grabbing assembly 530 to descend to grab the foam cotton 20 at the top. The displacement assembly 510 drives the lifting assembly 520 backward to the top of the pallet 10 at the output end of the conveying channel 200. The lifting assembly 520 drives the grabbing assembly 530 to descend, so that the grabbing assembly 530 releases the foam cotton 20 onto the pallet 10 and moves the support rod 6 downward. 131, so that the horizontal height of the support plate 6132 is lower than the horizontal panel of the pallet 10, and the two sliders 6112 move toward the direction close to the pallet 10, so that the support plates 6132 on the support rods 6131 on the left and right sides of the pallet 10 penetrate into the bottom of the pallet 10, and the support rods 6131 are lifted upward. All the support plates 6132 lift the pallet 10 upward, and the two sliders 6112 are moved synchronously along the extension direction of the slide rail 6111 to realize the transfer of the pallet 10, thereby completing the entire process of automatic laying of the foam cotton 20.
