Description

Technical Field

[0001] The utility model relates to the technical field of palletizing, in particular to a palletizing conveyor belt. Background Art

[0002] After the aluminum sheets are blanked and formed, in order to facilitate storage and transportation, the aluminum sheets need to be palletized. In the prior art, generally, a palletizing machine is used to palletize the aluminum sheets. A blanking structure is provided on the palletizing machine, and the aluminum sheets are positioned through the blanking structure so that the aluminum sheets are stacked neatly. Between the palletizing machine and the punching press, a conveyor belt is usually used to transport the aluminum sheets, as shown in the patent application with the publication number CN212173784U. In the actual use process, it is found that there are the following technical problems in using a conventional conveyor belt to transport aluminum sheets for palletizing:

[0003] Due to the vibration of the punching press, the sheets to be palletized on the conveyor belt may be offset in the left-right direction, and the sheet receiving position of the palletizing machine is fixed. The offset sheets to be palletized are easily stuck at the blanking structure of the palletizing machine;

[0004] When the sheets to be palletized slide from the conveyor belt to the blanking structure of the palletizing machine, the dropping slope of the sheets to be palletized is relatively large. On the one hand, the sheets to be palletized are easily collided with the already palletized aluminum sheets, causing scratches. On the other hand, the too large dropping slope also increases the difficulty of rectifying the sheets to be palletized. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a palletizing conveyor belt to reduce or eliminate at least one of the above technical problems.

[0006] The palletizing conveyor belt described in the utility model includes a frame, at least two conveying rollers installed on the top of the frame, and a conveyor belt body sleeved on the at least two conveying rollers.

[0025] The following will illustrate the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the protection scope of the present invention.

[0026] It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner. Therefore, only the components related to the present invention are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0027] As Figure 1 and Figure 4 shown, a palletizing conveyor belt includes a frame 1, at least two conveyor rollers installed on the top of the frame 1, and a conveyor belt body 2 sleeved on the at least two conveyor rollers. The conveyor belt body 2 is used to convey the sheets to be palletized 17 from the rear to the front. The palletizing conveyor belt further includes a plurality of support rollers suspended on the upper side of the front end of the conveyor belt body 2. The rotation axes of the plurality of support rollers are all arranged in the left-right direction, and the plurality of support rollers are arranged at intervals in the front-rear direction. The plurality of support rollers are used to support the upper side of the sheets to be palletized 17 located at the front end of the conveyor belt body 2.

[0028] With the above technical solution, by providing a plurality of supporting rollers, the outer circumferential surface of the supporting rollers contacts the upper side surface of the sheet 17 to be palletized, which can support the upper side surface of the sheet 17 to be palletized. During the process of the sheet 17 to be palletized slipping off the conveyor belt body 2, it can support the sheet 17 to be palletized, making the dropping slope of the sheet 17 to be palletized gentler, which helps to reduce the possibility of scratching the sheet 17 to be palletized and also helps to reduce the difficulty of aligning the sheet 17 during the palletizing process.

[0029] During specific implementation, there is a gap between the plurality of supporting rollers and the conveyor belt body 2, and this gap can be set according to the thickness of the sheet 17 to be palletized, as long as the sheet 17 on the conveyor belt body 2 can smoothly enter this gap.

[0030] In some embodiments, the plurality of supporting rollers include the foremost first roller 5 and at least two second rollers 6 located behind the first roller 5. The at least two second rollers 6 are installed on the frame 1 through a detachable structure. The number of second rollers 6 to be installed can be selected according to the size of the sheet 17 to be palletized, which can prevent adverse effects on the conveyance of the sheet 17 to be palletized due to excessive number of supporting rollers.

[0031] In some embodiments, as Figures 1 to 4 shown, on the left and right sides of the front end of the top of the frame 1, a first side plate 3 and a second side plate 4 are respectively fixedly connected. The left and right ends of the plurality of supporting rollers are respectively rotatably connected to the first side plate 3 and the second side plate 4. The provision of the second side plate 4 and the second side plate 4 facilitates the installation of the supporting rollers. During specific implementation, the first side plate 3 and the second side plate 4 can be installed on the frame 1 by means of welding or fastener connection.

[0032] As a specific example, as Figure 2 and Figure 3 shown, at the front end of the first side plate 3 and the front end of the second side plate 4, first round holes for cooperating with the first shaft heads 501 at the left and right ends of the first roller 5 are provided. On the first side plate 3 and the second side plate 4, U-shaped grooves 401 for installing the second rollers 6 are provided. The second shaft heads 601 at both ends of the second roller 6 respectively cooperate with the U-shaped grooves 401 on the first side plate 3 and the U-shaped grooves 401 on the second side plate 4. On the first side plate 3 and the second side plate 4, limit plates 7 for limiting the second shaft heads 601 at the bottom of the U-shaped grooves 401 are respectively installed. During specific implementation, the limit plate 7 can be detachably connected to the first side plate 3 or the second side plate 4 through a first bolt 8 cooperating with a connection hole 402 on the first side plate 3 or the second side plate 4 and a first nut cooperating with the first bolt 8. An n-shaped groove 701 for cooperating with the second shaft head 601 can be provided on the limit plate 7, and the top of the n-shaped groove 701 and the bottom of the U-shaped groove 401 form a second round hole for cooperating with the second shaft head 601.

[0033] As a preferred example, three support rollers are suspended on the upper side of the front end of the conveyor belt body 2. The three support rollers can meet the usage requirements of most of the sheets 17 to be palletized.

[0034] In some embodiments, as Figure 5 shown, the palletizing conveyor belt further includes a guiding mechanism for guiding the sheets 17 to be palletized on the conveyor belt body 2. The guiding mechanism includes a first roller group arranged on the left side of the conveyor belt body 2 and a second roller group arranged on the right side of the conveyor belt body 2. The first roller group includes a plurality of first vertically arranged rollers 11 arranged in sequence along a first virtual straight line extending obliquely from back to front and to the right. The rotation axis of the first vertically arranged roller 11 extends in the up and down direction. The second roller group includes a plurality of second vertically arranged rollers 15 arranged in sequence along a second virtual straight line extending obliquely from back to front and to the left. The rotation axis of the second vertically arranged roller 15 extends in the up and down direction. With the above technical solution, when the sheets 17 to be palletized on the conveyor belt body 2 are greatly offset, the outer peripheral surface of the first vertically arranged roller 11 in the first roller group or the outer peripheral surface of the second vertically arranged roller 15 in the second roller group contacts the edge of the sheet 17 to be palletized, which can guide and correct the deviation of the sheet 17 to be palletized, greatly reduce the offset amount of the sheet 17 to be palletized, and help reduce the risk that the sheet 17 to be palletized is stuck at the blanking structure of the palletizing machine.

[0035] In some embodiments, the guiding mechanism further includes a first bracket 10 with a length extending along the first virtual straight line and a second bracket 14 with a length extending along the second virtual straight line. A plurality of first vertically arranged rollers 11 are installed on the first bracket 10, and a plurality of second rollers are installed on the second bracket 14. The first bracket 10 is fixedly installed on the frame 1 through a first adjustable structure so that the angle of the first virtual straight line extending obliquely from back to front and to the right is adjustable. The second bracket 14 is fixedly installed on the frame 1 through a second adjustable structure so that the angle of the second virtual straight line extending obliquely from back to front and to the left is adjustable. With the above technical solution, the guiding mechanism can be adjusted adaptively according to different punching machines, different shapes of the sheets 17 to be palletized, and different sizes of the sheets 17 to be palletized to ensure a good guiding and deviation correction effect.

[0036] During specific implementation, the front end and the rear end of the first bracket 10 can be fixedly installed on the first support plate 9 through two second bolts 12 and two second nuts. The first support plate 9 is fixedly connected to the left side of the top of the frame 1. Two first mounting holes on the first support plate 9 respectively cooperating with the two second bolts 12 are arranged as strip-shaped holes extending in the left and right direction, so that the angle of the first bracket 10 extending obliquely from back to front and to the right is adjustable.

[0037] The front end and the rear end of the second support 14 can be fixedly installed on the second support plate 13 through two third bolts 16 and two third nuts. The second support plate 13 is fixedly connected to the right side of the top of the frame 1. Two second mounting holes on the second support plate 13 that cooperate with the two third bolts 16 are arranged as strip-shaped holes extending along the left-right direction, so that the angle of the second support 14 inclined from back to front to the right is adjustable.

[0038] In some embodiments, the palletizing conveyor belt further includes a motor installed on the frame 1. The motor is drivingly connected to one of at least two conveying rollers. Specifically, the conveying rollers are rotatably installed on the top of the frame 1. The motor can be fixedly installed on the frame 1 through bolts. A belt drive mechanism can be used for driving connection between the output shaft of the motor and the conveying roller, and the motor is used to drive the conveying roller to rotate, thereby driving the conveyor belt body 2 to move.

[0039] As Figure 6 shown, in use, the palletizing conveyor belt is used to convey the sheets 17 to be palletized processed by the punching machine to the palletizing device 18.
