Description

Technical Field

[0001] The utility model belongs to the technical field of logistics transportation, and in particular relates to a cargo separation device for a transport pallet. Background Art

[0002] At present, there are more and more types of box cargo, and most of them are transported with pallets. Although this method is fast, it will greatly increase the cost of using pallets, and the cost of recycling pallets is relatively high. At the same time, in order to make full use of the space in the carriage to save freight, it is sometimes necessary to separate the cargo from the pallet before loading, and only transport the cargo without transporting the pallet. Therefore, separating the pallet from the box cargo can save the cost of using the pallet and increase the space in the carriage. However, since the pallet is pressed under the cargo, it is difficult to separate the pallet if the cargo is not destackered.

[0003] In actual work, manual loading and unloading is often used to separate boxed goods from pallets. As boxed goods are relatively large in size, manual loading and unloading of boxed goods generally requires manual handling, which greatly increases labor costs. This method not only wastes time, but also increases the labor intensity of workers; if ordinary pallets are replaced with detachable pallets for cargo and pallets and then loaded, the cost is very high because a large number of detachable pallets need to be purchased.

The ear 541 is hinged; the lower side of the rear end of the scissor frame 52 is hinged to the first connecting bracket 551 of the connecting bracket 55, and the upper side thereof is rotatably connected to the second rotating shaft 5521 on the second connecting bracket 552 of the connecting bracket 55; the scissor frame 52 includes two groups of first folding rod assemblies 521 and two groups of second folding rod assemblies 522, each of the first folding rod assemblies 521 and the second folding rod assemblies 522 is composed of two connecting rods hinged to each other, and a first hydraulic cylinder connecting rod 531 and a second hydraulic cylinder connecting rod 532 are arranged between the two groups of first folding rod assemblies 521 The hydraulic cylinder connecting rod 532, the first hydraulic cylinder connecting rod 531 is arranged at the lower part of the first connecting rod 5211 of the first folding rod assembly 521, and the second hydraulic cylinder connecting rod 532 is arranged at the upper part of the second connecting rod 5212 of the first folding rod assembly 521. The two ends of the hydraulic cylinder 53 are respectively connected to the first hydraulic cylinder connecting rod 531 and the second hydraulic cylinder connecting rod 532; when the goods 3 are blocked by the baffle 42, the hydraulic cylinder 53 drives the scissor frame 52 to unfold, drives the push plate 54 to move forward, and separates the goods 3 from the pallet 2. In actual work, the pallet with goods is placed on the left end of the roller conveyor line 1, and the pallet with goods is transported from the left end of the roller conveyor line 1 to the pallet collecting device 6 at the right end through the roller conveyor line 1. When blocked by the blocking device 4, the goods 3 are separated from the pallet 2 by the pallet separation mechanism 5, and the goods 3 are taken away by a forklift for transportation. Since the pallet 2 is not pressed by the goods 3, it will move to the right with the roller conveyor line 1 and enter the pallet collecting device 6, thereby completing the separation of the goods 3 from the pallet 2. In actual use, after the pallet 2 enters the pallet collecting device 6, the next pallet with goods is placed at the left end of the roller conveyor line 1. The separated pallet 2 can be reused to save costs. The adoption of this technical measure improves the separation efficiency between the box-type goods and the pallet 2, and can quickly complete the collection of the empty pallet 2, which has the advantages of saving costs, saving time, and effectively improving work efficiency.

[0055] like Figure 1 , Figure 2 , Figure 3 As shown, the roller conveyor line 1 includes a mounting frame 11, a roller and a side frame 12. The top of the mounting frame 11 is a rectangular structure. The side frames 12 are arranged on both sides of the top of the mounting frame 11, that is, the side frames 12 include a front side frame 121 arranged on the front side of the mounting frame 11 and a rear side frame 122 arranged on the rear side of the mounting frame 11. The side frame 12 is provided with a blocking member 13 for limiting, which includes a front side blocking member 131 and a rear side blocking member 132. The front side blocking member 131 and the rear side blocking member 132 are mainly used to prevent the pallet 2 from falling from the roller conveyor line 1. At the same time, it is necessary to ensure that the goods 3 will not be blocked from moving when the goods 3 are separated from the pallet 2. The height of the front side blocking member 131 and the front side blocking member 131 arranged on the side frame 12 of the roller conveyor line 1 is less than the height of the pallet 2. The roller conveyor line 1 is arranged horizontally, and the side frame 12 of the roller conveyor line 1 is provided with a blocking device 4 for limiting the rightward movement of the pallet 2 carrying goods.

[0056] like Figure 1 — Figure 3 As shown, in actual use, the blocking device 4 is arranged near the side of the pallet collecting device 6. When the pallet 2 is separated from the goods 3, the distance the pallet 2 moves to the pallet collecting device 6 is reduced. The blocking device 4 includes an n-type bracket 41 fixedly connected to the front side frame 121 and the rear side frame 122 and a baffle 42 arranged at the upper end of the n-type bracket. The baffle 42 is used to block the goods 3. The n-type bracket 41 allows the pallet 2 to pass through after the goods 3 are separated. The pallet 2 moves toward the pallet collecting device 6 after passing through the n-type bracket 41. In actual use, the n-type bracket 41 is made of metal material, which is arranged along the longitudinal direction of the roller conveyor line 1, and its lower two ends are respectively connected to the upper end of the front side frame 121 and the upper end of the rear side frame 122. The through hole height of the n-type bracket 41 must be greater than the height of the pallet 2, and it is necessary to ensure that the pallet 2 can pass smoothly. The baffle 42 is generally a square structure, and its length is generally equal to or greater than the width of the roller conveyor line 1. The baffle 42 is fixedly arranged at the upper end of the n-type bracket 41.

[0057] like Figure 1 , Figure 2 As shown, a cargo tray separation mechanism 5 for separating the cargo 3 from the pallet 2 is provided on the left side of the blocking device 4, and a pallet collecting device 6 is provided on the right end of the roller conveyor line 1.

[0058] like Figure 1 — Figure 6As shown, the pallet separation mechanism 5 includes a fixed bracket 5, a scissor frame 52, a hydraulic cylinder 53 and a push plate 54 fixedly installed at the rear side of the roller conveyor line 1. Specifically, the fixed bracket 5 is fixedly installed at the rear side of the roller conveyor line 1, and is mainly used to connect and support other parts of the pallet separation mechanism 5. In actual use, a fixed platform can also be used, and the fixed platform is made of a support plate and a support bracket.

[0059] like Figure 1 — Figure 6 As shown, a connecting bracket 55 for connecting the scissor frame 52 is fixedly provided on the fixed bracket 5. The connecting bracket 55 includes a first connecting bracket 551 composed of two oppositely arranged connecting plates and a second connecting bracket 552 in an N-shaped structure. The first connecting bracket 551 is lower than the second connecting bracket 552, and the first connecting bracket 551 is arranged inside the second connecting bracket 552. The upper side of the front end of the scissors frame 52 is rotatably connected to the first rotating shaft 542 on the rear side of the push plate 54, and the lower side is hinged to the connecting ear 541 on the rear side of the push plate 54; the lower side of the rear end of the scissors frame 52 is hinged to the first connecting bracket 551 of the connecting bracket 55, and the upper side is rotatably connected to the second rotating shaft 5521 on the second connecting bracket 552 of the connecting bracket 55; the scissors frame 52 includes two groups of first folding rod assemblies 521 and two groups of second folding rod assemblies 522, and the first folding rod assemblies 521 and the two groups of second folding rod assemblies 522 are hinged to each other; the first folding rod assembly 521 and the second folding rod assembly 522 are each composed of two mutually hinged The first hydraulic cylinder connecting rod 531 and the second hydraulic cylinder connecting rod 532 are arranged between the two groups of first folding rod assemblies 521. The first hydraulic cylinder connecting rod 531 is arranged at the lower part of the first connecting rod 5211 of the first folding rod assembly 521, and the second hydraulic cylinder connecting rod 532 is arranged at the upper part of the second connecting rod 5212 of the first folding rod assembly 521. The two ends of the hydraulic cylinder 53 are respectively connected to the first hydraulic cylinder connecting rod 531 and the second hydraulic cylinder connecting rod 532. When the goods 3 are blocked by the baffle 42, the hydraulic cylinder 53 drives the scissor frame 52 to unfold and drives the push plate 54 to move forward, so that the goods 3 are separated from the pallet 2. In actual use, when the goods 3 are separated from the pallet 2, the hydraulic cylinder 53 drives the scissor frame 52 to shrink and drives the push plate 54 to retreat and return to the initial position. At the initial position, the front end surface of the push plate 54 is near the rear side of the rear side frame 122. The push plate 54 is mainly used to push the goods 3, so the lower end surface of the push plate 54 corresponds to the upper end surface of the pallet 2, and the upper end surface of the push plate 54 is higher than the upper end surface of the goods 3; the lengths of the left and right ends of the push plate 54 are greater than the length of the pallet 2. In actual use, the length of the goods 3 after stacking is greater than the length of the pallet 2, so the length of the push plate 54 needs to be greater than the length of the pallet 2.

[0060] like Figure 3As shown, the connecting ear 541 on the rear side of the push plate 54 is arranged at the lower part of the rear side of the push plate 54 , and the first rotating shaft 542 on the rear side of the push plate 54 is rotatably arranged at the upper part of the rear side of the push plate 54 .

[0061] like Figure 2 — Figure 6 As shown, the lower end of the first connecting rod 5211 is hinged to the connecting ear 541 on the rear side of the push plate 54, and the lower end of the second connecting rod 5212 is hinged to the first connecting bracket 551; the upper end of the first connecting rod 5211 is hinged to the upper end of the second connecting rod 5212; the second folding rod assembly 522 includes a third connecting rod 5221 and a fourth connecting rod 5222, the upper end of the third connecting rod 5221 is rotatably connected to the first rotating shaft 542 on the rear side of the push plate 54, and the upper end of the fourth connecting rod 5222 is rotatably connected to the second rotating shaft 5521 on the second connecting bracket 552; the lower end of the third connecting rod 5221 is hinged to the lower end of the fourth connecting rod 5222; the middle part of the first connecting rod 5211 is hinged to the middle part of the third connecting rod 5221, and the middle part of the second connecting rod 5212 is hinged to the middle part of the fourth connecting rod 5222. A reinforcement plate 56 is further provided at the lower part between the two first connecting rods 5211 and the upper part of the two second connecting rods 5212. In actual use, the cargo tray separation mechanism 5 needs to separate the cargo 3 from the pallet 2, and at the same time, it needs to ensure its stability when pushing the cargo 3, and the overall force is uniform when pushing. The cargo tray separation mechanism 5 adopts a scissor frame 52 structure, which has the technical effect of a large pushing range and uniform overall force.

[0062] like Figure 1 , Figure 7 As shown, the roller conveyor line 1 is also provided with a pallet blocking plate assembly 7 for blocking the left side of the pallet 2. The pallet blocking plate assembly 7 includes a first cylinder 71 fixedly connected to the longitudinal beam of the mounting frame 11 of the roller conveyor line 1 and a pallet blocking plate 72 installed on the upper end of the output shaft of the first cylinder 71; the pallet blocking plate 72 corresponds to the gap between two adjacent rollers of the roller conveyor line 1; when the goods 3 are blocked by the baffle 42, the first cylinder 71 is started to drive the pallet blocking plate 72 to rise, so that the pallet blocking plate 72 passes through the gap between the adjacent rollers, so that the right side of the pallet blocking plate 72 corresponds to the left side of the pallet 2. By providing a pallet blocking plate 72 that can be raised and lowered, the pallet 2 can be restricted from moving to the left.

[0063] like Figure 7As shown, in actual use, the first cylinder 71 is two cylinders spaced apart from each other, and a mounting portion 73 is provided on the output shaft of the first cylinder 71, and the mounting portion 73 is provided with a groove for mounting a pallet blocking plate 72, and the pallet blocking plate 72 is mounted in the groove. Specifically, a longitudinal beam is provided under the mounting frame 11 of the roller conveyor line 1, and the first cylinder 71 is spaced apart and arranged on the longitudinal beam. At the same time, the pallet blocking plate 72 corresponds to the gap between adjacent rollers, that is, when the pallet blocking plate 72 rises, it needs to pass through the gap between adjacent rollers.

[0064] like Figure 1 , Figure 8 — Fig.10 As shown, the pallet collecting device 6 comprises a collecting frame 61, a collecting bin 62 arranged on the collecting frame 61, a lifting device 63 and a hook device 65.

The output shaft of the second cylinder 631 is provided with a lifting plate 632 for cooperating with the bottom of the pallet 2. After the pallet 2 enters the collection bin 62 from the pallet entrance through the conveying chain device 64, the second cylinder 631 drives the lifting plate 632 to lift the pallet 2 upward, so that the forklift hole of the pallet 2 cooperates with the hook 655 of the hook device 65. After the hook 655 hooks the pallet 2, the second cylinder 631 drives the lifting plate 632 to move downward, and reciprocates in sequence. After enough pallets 2 are collected in the collection bin 62, the pallets 2 are transferred as a whole. In order to facilitate the transfer of the pallets 2, no side plate is provided on the front side of the collection bin 62. The collecting bin 62 is composed of three side panels, including a left side panel 621 , a right side panel 622 and a rear side panel 623 . An opening is provided between the rear side panel 612 of the collecting bin and the rear side panel 612 of the collecting rack 61 for the rear hook 655 to move.
