Description

Technical Field

[0001] The present invention relates to the technical field of palletizing devices, and in particular to a palletizing device and a palletizing method for processing decorative floors. Background Art

[0002] Wooden flooring is a commonly used material for interior decorative flooring. During the processing and production of decorative wooden flooring, palletizing equipment is needed to palletize the flooring so that it can be stacked according to certain rules and methods for easy storage, transportation and management.

[0003] The current floor palletizing equipment is completed by using two conveyor belts with a height difference. The upper conveyor belt transports the wooden floor to the stacking area, and the lower conveyor belt stacks it to the same height as the upper conveyor belt. The stacked wooden boards are then transported to the packaging area for packaging. During this process, due to the inertia of the wooden floor during transportation, the wooden floor is prone to collision and displacement during the falling process, resulting in uneven floor stacking.

[0007] The clamping and alignment assembly includes an electric lifting rod, which is fixedly installed at the bottom of the stacking carrier plate. A lifting bracket is fixedly sleeved on the output shaft of the electric lifting rod. Both ends of the lifting bracket are rotatably matched with one end of the connecting rod, and the other end of the connecting rod is rotatably matched with one end of the push-pull rod. The other end of the push-pull rod is fixedly connected with a synchronization rod, and a limiting groove is provided at the end of the synchronization rod. A synchronization gear plate is extended on one side of the limiting groove. The two ends of the supporting splint are slidably installed in the limiting groove through a rotating shaft. A synchronization gear is fixedly sleeved on the rotating shaft, and the synchronization gear is meshed with the synchronization gear plate.

[0008] As a further solution of the present invention: a first slide plate is fixedly provided at the bottom of the front and rear sides of the stacking carrier, a second slide plate is fixedly provided between the first slide plates, a rotating slide is rotatably provided on the rotating shaft, and the rotating slide is adapted to be slidably installed in the first slide plate.

[0009] As a further solution of the present invention: a pair of linear slides are adapted to be slidably installed in the second slide plate, an extrusion spring is arranged between the linear slide and the second slide plate, a roller is rotatably installed at one end of each linear slide, and a straightening plate is fixedly arranged at the other end of the linear slide, and an eccentric shifting block is fixedly connected to the bottom of the output end of the electric lifting rod through a connecting plate, and the two rollers are symmetrically abutted against the two side walls of the eccentric shifting block.

[0010] As a further solution of the present invention: a fixed plate is fixedly provided at the bottom of the stacking carrier plate, the push-pull rod slides through the fixed plate, and a return spring is provided between the end of the synchronization rod and the fixed plate.

[0011] As a further solution of the present invention: the supporting splint is kept flush with the stacking carrier in a horizontal state, and the time taken for the rotating shaft to slide the limit distance in the limiting groove is equal to the time taken for the synchronous gear to engage and rotate a quarter of a circle.

[0012] As a further solution of the present invention: sliding grooves are provided on both sides of the transition conveyor platform along the length direction, sliding blocks are adapted to be slidably installed in the sliding grooves, a follower pin is rotatably installed on one side of the sliding block, and a guide plate is horizontally extended from one end of the stacking carrier close to the transition conveyor platform, the guide plate is abutted against both sides of the transition conveyor platform, a straight groove is horizontally provided on one side of the guide plate, and the follower pin is slidably installed in the straight groove.

[0013] As a further solution of the present invention: a baffle is provided on one end of the stacking carrier plate extending upward away from the transition conveyor platform.

[0014] The present invention also provides a palletizing method for processing decorative flooring, which uses the above-mentioned palletizing device for processing decorative flooring and includes the following steps:

[0015] Step 1: The floor is fed, the feeding conveyor starts, and the floors are placed on it one by one and transported forward. The floors will be guided to the stacking carrier through the transition conveyor and supported by the supporting plywood to prepare for stacking.

[0016] Step 2: Clamping on the left and right. The electric lifting rod drives the synchronous rods at both ends to move linearly through the connecting rod, and uses the synchronous tooth plate and synchronous gear to drive the supporting splints at both ends to rotate 90° and approach each other. The floor will fall on the unloading conveyor table along the deflected supporting splints. At the same time, the supporting splints approaching each other will clamp the floor on the left and right.

[0017] Step 3: Align the floor forward and backward. During the clamping process, the electric lifting rod will synchronously drive the eccentric shifting block to move up and down, and the rollers on both sides will move accordingly, so that the linear slide will drive the shifting plate to move back and forth in a straight line to align the floor forward and backward.

[0018] Step 4: Palletizing and unloading. When the floor is palletized to the specified height, the lifting cylinder drives the palletizing carrier to move upward to make way, and the unloading conveyor starts. The palletized floor will be transported forward along the unloading conveyor to be unloaded.

[0019] Beneficial effects of the present invention:

[0020] (1) By setting up a stacking carrier and a supporting plywood, when starting to stack, the feed conveyor is started, and the floors are placed on it one by one and transported forward. The floors will be guided to the stacking carrier by the transition conveyor and supported by the supporting plywood to prepare for stacking. The supporting plywood plays the role of transferring the floors, so that the floors do not fall directly from the feed conveyor to the unloading conveyor, but are transferred by the supporting plywood. As the supporting plywood rotates downward, the floors will also fall straight down with the supporting plywood, thereby ensuring that the stacking position of each floor remains uniform, so that the floors can be accurately stacked vertically one by one during stacking, avoiding the collision of the floors due to the inertia during horizontal transportation, which is beneficial to the stacking process.

[0021] (2) By setting up a clamping and alignment component, when stacking, the electric lifting rod drives the lifting bracket to move downward, and the lifting bracket will drive the synchronous rods at both ends to move linearly through the connecting rod and the push-pull rod. During this process, the synchronous gear plate will drive the supporting splint to rotate 90 degrees through the synchronous gear. The floor originally supported on it will also gradually fall with the rotation of the supporting splint. At the same time, the synchronous rod will pull the supporting splints at both ends closer together through the limit groove. At this time, the vertical supporting splint will clamp the left and right ends of the stacking floor. Through the deflection process of the supporting splint, it can flexibly switch between the supporting and clamping functions, which is convenient for use.

[0022] (3) By setting up the correction plate, during the clamping process, the electric lifting rod will synchronously drive the eccentric shift block to move downward. Under the elastic force of the extrusion spring, the rollers on both sides will move inward as the eccentric shift block moves downward, so that the linear slide drives the correction plate to move linearly. When the electric lifting rod moves upward to drive the supporting clamp to reset, the linear slide will drive the correction plate to move linearly in the opposite direction, so that the correction plate can move back and forth, thereby correcting the deviation and aligning the stacked floor. In conjunction with the clamping process, it can ensure that the floor is stacked neatly, which is conducive to improving the stacking effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] See also Figure 1 、 Figure 3 and Figure 4 As shown, the present invention is a stacking device for decorative floor processing, comprising a frame 1, wherein a feed conveyor 2, a transition conveyor 4 and a discharge conveyor 3 are arranged on the upper end of the frame 1 in sequence. The feed conveyor 2 is positioned higher than the discharge conveyor 3, the transition conveyor 4 is inclined, and both ends of the transition conveyor 4 are smoothly connected with the feed conveyor 2 and the discharge conveyor 3 respectively. A mounting frame 5 is fixedly provided on the upper end of the frame 1, and lifting cylinders 7 are fixedly provided on both sides of the mounting frame 5. The output end of the lifting cylinder 7 is fixedly connected to a stacking carrier 6, which is located above the discharge conveyor 3, and a through opening for the floor to pass through is provided in the center of the stacking carrier 6, and clamping and alignment components 8 are symmetrically provided on the bottom of the front and rear sides of the stacking carrier 6, and a group of supporting splints 9 are symmetrically installed on the left and right ends of the stacking carrier 6 for rotation.

[0035] Specifically, by setting the stacking carrier 6 and the supporting plywood 9, when palletizing begins, the feed conveyor platform 2 is started, and the floors are placed on it one by one and transported forward. The floors will be guided by the transition conveyor platform 4 to the stacking carrier 6, and supported by the supporting plywood 9 to prepare for palletizing, wherein the supporting plywood 9 plays the role of transferring the floor, so that the floor does not fall directly from the feed conveyor platform 2 to the unloading conveyor platform 3, but is transferred by the supporting plywood 9. As the supporting plywood 9 rotates downward, the floor will also fall straight down with the supporting plywood 9, thereby ensuring that the stacking position of each floor remains uniform, so that the floors can be accurately stacked vertically one by one during stacking, avoiding the collision of the floors due to the inertia during horizontal transportation, which is beneficial to the stacking process.

[0036] A baffle 63 is provided on one end of the stacking carrier plate 6 away from the transition conveying platform 4 and extends upward.

[0037] Specifically, the function of the baffle 63 is to timely block and limit the floor that is being transported to the palletizing carrier 6, so that the floor can be accurately supported by the supporting plates 9 at both ends to facilitate the subsequent palletizing process.

[0038] like Figure 5 、 Figure 6 and Figure 7As shown, the clamping and alignment component 8 includes an electric lifting rod 81, which is fixedly installed at the bottom of the stacking carrier 6. A lifting bracket 82 is fixedly sleeved on the output shaft of the electric lifting rod 81. Both ends of the lifting bracket 82 are rotatably matched with one end of the connecting rod 83, and the other end of the connecting rod 83 is rotatably matched with one end of the push-pull rod 84. The other end of the push-pull rod 84 is fixedly connected with a synchronization rod 85. A limiting groove 851 is provided at the end of the synchronization rod 85, and a synchronization gear plate 852 is extended on one side of the limiting groove 851. The two ends of the supporting splint 9 are slidably installed in the limiting groove 851 through the rotating shaft 91. A synchronization gear 93 is fixedly sleeved on the rotating shaft 91, and the synchronization gear 93 is meshed with the synchronization gear plate 852. The synchronization rod 85 drives the supporting splints 9 at both ends to rotate 90° and move closer to each other.

[0039] Specifically, by setting up the clamping and alignment component 8, when stacking, the electric lifting rod 81 drives the lifting bracket 82 to move downward, and the lifting bracket 82 will drive the synchronization rod 85 at both ends to move linearly through the connecting rod 83 and the push-pull rod 84. During this process, the synchronization gear plate 852 will drive the supporting splint 9 to rotate 90° through the synchronization gear 93, and the floor originally supported on it will also gradually fall with the rotation of the supporting splint 9. At the same time, the synchronization rod 85 will pull the supporting splints 9 at both ends gradually closer through the limit groove 851. At this time, the vertical supporting splint 9 will clamp the left and right ends of the stacking floor. Through the deflection process of the supporting splint 9, it can flexibly switch between the supporting and clamping functions, which is convenient to use.

[0040] The supporting plate 9 is kept flush with the palletizing plate 6 in a horizontal state, and the time taken for the rotating shaft 91 to slide the limit distance in the limiting groove 851 is equal to the time taken for the synchronous gear 93 to mesh and rotate a quarter of a circle.

[0041] Specifically, in the initial state, the supporting plate 9 is kept horizontal and flush with the stacking carrier 6, which allows the floor to slide smoothly onto the supporting plate 9 and be supported. At this time, the rotating shaft 91 is located at the inward end of the limiting groove 851, as shown in FIG. Figure 6 When the synchronization rod 85 starts to move horizontally, the synchronization rod 85 will first drive the synchronization gear plate 852 to move, thereby causing the supporting clamp plate 9 to start rotating. When it rotates 90 degrees, the shaft 91 will slide relatively to the other end of the limit slot 851, as shown in FIG. Figure 7 As shown, at this time, the limit groove 851 will apply a pulling force to the rotating shaft 91, and the synchronization rod 85 will no longer move relative to the rotating shaft 91, so that the supporting splint 9 will stop rotating immediately when it rotates to 90°, and maintain a vertical state and move closer to each other.

[0042] like Figure 5 and Figure 6As shown, the bottom of the front and rear sides of the stacking carrier 6 are fixedly provided with a first slide plate 64, a second slide plate 65 is fixedly provided between the first slide plates 64, and a rotating slide 92 is rotatably provided on the rotating shaft 91, and the rotating slide 92 is adapted to be slidably installed in the first slide plate 64.

[0043] Specifically, by providing the rotating slide 92 , a support function can be provided for the rotating shaft 91 , so that the supporting splint 9 can smoothly rotate and can also move horizontally along the first slide plate 64 along with the rotating slide 92 .

[0044] like Figure 8 As shown, a pair of linear slides 88 are adapted to be slidably installed in the second slide plate 65, and an extrusion spring 882 is arranged between the linear slide 88 and the second slide plate 65. A roller 881 is rotatably installed at one end of each linear slide 88, and a straightening plate 89 is fixedly arranged at the other end of the linear slide 88. The bottom of the output end of the electric lifting rod 81 is fixedly connected to the eccentric shifting block 87 through a connecting plate, and the two rollers 881 are symmetrically pressed against the two side walls of the eccentric shifting block 87.

[0045] Specifically, by setting the correction plate 89, during the clamping process, the electric lifting rod 81 will synchronously drive the eccentric shift block 87 to move downward. Under the elastic force of the extrusion spring 882, the rollers 881 on both sides will move inward as the eccentric shift block 87 moves downward, thereby allowing the linear slide 88 to drive the correction plate 89 to move linearly. When the electric lifting rod 81 moves upward to drive the supporting clamp 9 to reset, the linear slide 88 will drive the correction plate 89 to move linearly in the opposite direction, thereby allowing the correction plate 89 to move back and forth, thereby correcting the deviation and aligning the stacked floor. In conjunction with the clamping process, it can ensure that the floor is stacked neatly, which is conducive to improving the stacking effect.

[0046] like Figure 5 As shown, a fixed plate 66 is fixedly provided at the bottom of the stacking carrier 6 , the push-pull rod 84 slides through the fixed plate 66 , and a return spring 86 is provided between the end of the synchronization rod 85 and the fixed plate 66 .

[0047] Specifically, the fixed plate 66 can provide stable support for the linear movement process of the push-pull rod 84, so that the linear movement process of the push-pull rod 84 is balanced and stable. At the same time, the reset spring 86 can help the synchronization rod 85 drive the supporting splint 9 to reset.

[0048] like Figure 2 and Figure 3As shown, sliding grooves 41 are provided on both sides of the transition conveyor platform 4 along the length direction, and a sliding block 41 is adapted to be slidably installed in the sliding groove 41. A follower pin 43 is rotatably installed on one side of the sliding block 41. A guide plate 61 is horizontally extended from one end of the stacking carrier 6 close to the transition conveyor platform 4. The guide plate 61 is abutted against both sides of the transition conveyor platform 4. A straight groove 62 is horizontally provided on one side of the guide plate 61, and the follower pin 43 is slidably installed in the straight groove 62.

[0049] Specifically, by setting the guide plate 61, when the height of the stacking carrier 6 is adjusted by the lifting cylinder 7, the sliding block 41 will slide accordingly along the sliding groove 41, and the follower pin 43 will always keep sliding in the straight groove 62, so that the guide plate 61 can always maintain a smooth connection and transition with the transition conveyor platform 4, and then the floor can be transported to the stacking carrier 6 along the guide plate 61.

[0050] The working principle of the stacking device in the present invention is as follows: when palletizing begins, the feed conveyor table 2 is started, and the floors are placed on it one by one and transported forward. The floors will be guided by the transition conveyor table 4 to the stacking carrier 6, and supported by the supporting plywood 9 to prepare for stacking, wherein the supporting plywood 9 plays the role of transferring and transitioning the floors, so that the floors do not fall directly from the feed conveyor table 2 to the unloading conveyor table 3, but are transferred by the supporting plywood 9. As the supporting plywood 9 rotates downward, the floors will also fall straight down with the supporting plywood 9, thereby ensuring that the stacking position of each floor remains uniform, so that the floors can be accurately stacked vertically one by one during stacking. During stacking, the electric lifting rod 81 drives the lifting bracket 82 to move downward, and the lifting bracket 82 will drive the synchronous rods 85 at both ends to move linearly through the connecting rod 83 and the push-pull rod 84. During this process, the synchronous gear plate 852 will drive the supporting splint 9 to rotate 90 degrees through the synchronous gear 93. The floor originally supported on it will also gradually fall with the rotation of the supporting splint 9. At the same time, the synchronous rod 85 will pull the supporting splints 9 at both ends gradually closer through the limit slot 851. At this time, the vertical supporting splint 9 will clamp the left and right ends of the stacking floor. The lowering rod 81 will synchronously drive the eccentric shifting block 87 downward. Under the elastic force of the extrusion spring 882, the rollers 881 on both sides will move inward as the eccentric shifting block 87 moves downward, thereby causing the linear slide 88 to drive the straightening plate 89 to move linearly. When the electric lifting rod 81 moves upward to drive the supporting clamp 9 to reset, the linear slide 88 will drive the straightening plate 89 to move linearly in the opposite direction, thereby allowing the straightening plate 89 to move back and forth, thereby correcting the deviation and aligning the stacked floor. In conjunction with the clamping process, it can ensure that the floor is stacked neatly. When the floor is stacked to the specified height, the lifting cylinder 7 drives the stacking carrier 6 to move upward to make way, and the unloading conveyor 3 is started. The stacked floor will be transported forward along the unloading conveyor 3 for unloading.

[0051] The present invention also provides a palletizing method for processing decorative flooring, which uses the above-mentioned palletizing device for processing decorative flooring and includes the following steps:

[0052] Step 1: Floor feeding, the feeding conveyor 2 is started, and the floors are placed on it one by one and transported forward. The floors will be guided by the transition conveyor 4 to the stacking carrier 6 and supported by the supporting splint 9 to prepare for stacking.

[0053] Step 2: Clamping to the left and right. The electric lifting rod 81 drives the synchronous rod 85 at both ends to move linearly through the connecting rod 83, and uses the synchronous gear plate 852 and the synchronous gear 93 to drive the supporting splints 9 at both ends to rotate 90° and approach each other. The floor will fall on the unloading conveying platform 3 along the deflected supporting splints 9, and at the same time, the supporting splints 9 approaching each other will clamp the floor to the left and right.

[0054] Step 3: Aligning the floor forward and backward. During the clamping process, the electric lifting rod 81 will synchronously drive the eccentric shifting block 87 to move up and down, and the rollers 881 on both sides will move accordingly, so that the linear slide 88 drives the alignment plate 89 to move back and forth linearly to align the floor forward and backward.

[0055] Step 4: Palletizing and unloading. When the floors are palletized to a specified height, the lifting cylinder 7 drives the palletizing carrier 6 to move upward to make way, and the unloading conveyor platform 3 starts. The palletized floors will be transported forward along the unloading conveyor platform 3 for unloading.

[0056] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.

When the floor is palletized to a specified height, the lifting cylinder (7) drives the palletizing carrier (6) to move upward to make way, and the unloading conveyor (3) starts. The palletized floor will be transported forward along the unloading conveyor (3) to be unloaded.
