Description

Technical Field

[0001] The utility model belongs to the technical field of palletizing equipment, and in particular relates to a rotating device and a palletizer thereof. Background Art

[0002] After the products are sealed in boxes, in order to save space, the boxes need to be palletized, that is, the boxes are stacked in multiple layers, with multiple boxes on each layer. However, if the placement direction of the boxes is single, that is, the boxes on the upper layer are completely overlapped with the boxes on the lower layer, the overall center of gravity of the boxes on the transfer pallet will be unstable, and it will be easy to tip over, causing damage to the products. Therefore, some of the boxes are rotated so that the directions of the boxes on different layers are staggered, and one box is at least in contact with the two lower layers of boxes, so that the boxes stacked on the transfer pallet as a whole are not easy to tip over. The existing technology uses a palletizer, which picks up a single box through a robotic arm and other devices, rotates the direction, and then places it on the transfer pallet, but this method is time-consuming and inefficient, and is not conducive to improving the transfer efficiency of the boxes.

The terms "first," "objective," and the like in the specification, claims, or accompanying drawings are used to distinguish similar objects and are not necessarily intended to describe a specific sequence or precedence.

[0021] An embodiment of the utility model includes: a first conveyor belt, the first conveyor belt is used to convey packaging boxes along a first direction; a rotating device, the rotating device is located on the first side of the first conveyor belt, the rotating device includes an arc block and a connecting rod, the arc block is connected to one end of the connecting rod, the connecting rod is used to drive the arc block to enter or leave the top of the first conveyor belt along the second direction, the arc block protrudes toward the second direction, wherein, when the arc block is in an extended state, the distance between the arc block and the second side of the first conveyor belt is less than the length of the packaging box, the second side is the opposite side of the first side, and the second direction is opposite to the first direction. According to the technical solution of this embodiment, the packaging box can be rotated in the conveyor belt by the arc block, so that the packaging box can be adjusted in the right direction before palletizing, thereby improving the transportation efficiency of the packaging box.

[0022] Reference Figure 1 and Figure 2 , the rotating device provided in this embodiment includes:

[0023] A first conveyor belt 20, the first conveyor belt 20 is used to convey the packaging box 10 along a first direction;

[0024] The rotating device 30 is located on the first side of the first conveyor belt 20. The rotating device 30 includes an arc block 31 and a connecting rod 32. The arc block 31 is connected to one end of the connecting rod 32. The connecting rod 32 is used to drive the arc block 31 to enter or leave the top of the first conveyor belt 20 along the second direction. The arc block 31 protrudes toward the second direction. When the arc block 31 is in an extended state, the distance between the arc block 31 and the second side of the first conveyor belt 20 is less than the length of the packaging box 10. The second side is the opposite side of the first side, and the second direction is opposite to the first direction.

[0025] It should be noted that the rotating device of this embodiment does not include the packaging box 10. During the implementation process, the packaging box 10 is fed into the first conveyor belt 20 by external equipment or operators. The rotating device of this application adjusts the direction of the packaging box 10 before stacking the packaging box 10 to improve the transfer efficiency of the packaging box 10.

[0026] It should be noted that the feeding end of the first conveyor belt 20 is the end of the first conveyor belt 20 close to the second direction, the discharging end of the first conveyor belt 20 is the end of the first conveyor belt 20 close to the first direction, and the first side and the second side of the first conveyor belt 20 are not one side of the discharging end or the feeding end of the first conveyor belt 20.

[0027] It should be noted that the connecting rod 32 drives the arc block 31 to enter the top of the first conveyor belt 20. When the arc block 31 is located above the first conveyor belt 20, the arc block 31 can abut against the packaging box 10; the connecting rod 32 drives the arc block 31 to leave the top of the first conveyor belt 20. When the arc block 31 is not located directly above the first conveyor belt 20, the arc block 31 cannot abut against the packaging box 10.

[0028] It should be noted that the distance between the arc block 31 and the second side of the first conveyor belt 20 is less than the length of the packaging box 10. Therefore, the arc block 31 does not block the packaging box 10 from moving in the first direction. When the packaging box 10 is in contact with the arc block 31, the packaging box 10 rotates horizontally along the arc block 31. During this horizontal rotation, the packaging box 10 moves in the first direction. After the packaging box 10 has adjusted its direction, it moves in the first direction.

[0029] It should be noted that when the packaging box 10 is positioned in the second direction of the arc block 31, the side of the packaging box 10 that is closest to the first direction serves as the contact surface between the packaging box 10 and the arc block 31. When the arc block 31 enters above the first conveyor belt 20 and the packaging box 10 moves in the first direction, the contact surface can abut against the arc block 31. When the contact surface abuts against the arc block 31, the arc block 31 applies a force perpendicular to the contact surface to the packaging box 10. When the contact surface is parallel to the first direction, that is, when the packaging box 10 has completed its orientation adjustment, no force is applied between the arc block 31 and the packaging box 10. The first conveyor belt 20 conveys the packaging box 10 in the first direction. When the packaging box 10 is positioned in the first direction of the rotating device 30, the contact surface of the packaging box 10 is parallel to the first direction.

[0030] It should be noted that the packaging box 10 is placed on the first conveyor belt 20, and the first conveyor belt 20 conveys the packaging box 10 along the first direction. The packaging box 10 moves along the first direction, and the packaging box 10 abuts against the arc block 31. The arc block 31 provides a thrust perpendicular to the contact surface to the packaging box 10. The packaging box 10 rotates horizontally along the arc block 31. When the contact surface is parallel to the first direction, the packaging box 10 completes the direction adjustment, and the packaging box 10 with the adjusted stacking direction moves along the first direction. Through the rotating device of the present application, the direction of the packaging box 10 during stacking can be adjusted before the packaging box 10 is stacked, thereby improving the transportation efficiency of the packaging box 10.

[0031] In addition, in one embodiment, referring to Figure 2 The rotating device 30 also includes a cylinder 33, which is connected to one end of the connecting rod 32 that is not connected to the arc block 31, and the cylinder 33 is used to drive the connecting rod 32 to move.

[0032] It should be noted that the piston rod of the cylinder 33 is connected to the end of the connecting rod 32 that is not connected to the arc block 31. The cylinder 33 is used to drive the connecting rod 32 to enter or leave the top of the first conveyor belt 20. When the cylinder 33 works, the piston rod of the cylinder 33 moves linearly in the cylinder barrel of the cylinder 33, and the piston rod of the cylinder 33 drives the connecting rod 32 to move.

[0033] In addition, in one embodiment, referring to Figure 1 and Figure 2 , also includes a first sensor 21, the first sensor 21 is located above the first conveyor belt 20, the first sensor 21 is located in the second direction of the rotating device 30, and the first sensor 21 is electrically connected to the cylinder 33.

[0034] It should be noted that the first sensor 21 can be a beam grating, and the light receiver and light emitter of the beam grating are fixed on both sides of the first conveyor belt 20. When a package box 10 passes through the first sensor 21, the package box 10 blocks the light signal emitted by the light emitter, the light receiver does not receive the light signal, and the beam grating generates an electrical signal.

[0035] It should be noted that the first sensor 21 detects the passing of the box, and the first sensor 21 generates an electrical signal and sends it to the cylinder 33. After the cylinder 33 receives the electrical signal, the cylinder 33 drives the connecting rod 32 to move, and the connecting rod 32 drives the arc block 31 to move above the first conveyor belt 20, so that the arc block 31 can abut against the packaging box 10, thereby realizing the horizontal rotation of the packaging box 10.

[0036] In addition, in one embodiment, referring to Figure 1 and Figure 2 The first conveyor belt 20 is a roller conveyor belt, and the first conveyor belt 20 includes a plurality of first rollers and a plurality of second rollers 22 . The first rollers are electrically driven rollers, and the second rollers 22 are passive rollers. The second rollers 22 are aligned with the rotating device 30 .

[0037] It should be noted that the first conveyor belt 20 is a roller conveyor belt, and the alignment of the first conveyor belt 20 with the rotating device 30 can decelerate the packaging box 10. The first roller, which is an electrically driven roller, continuously rotates when the first conveyor belt 20 is in operation. When the packaging box 10 moving in the first direction passes over the second roller 22, the second roller 22, which is a passive roller, slows the movement of the packaging box 10 in the first direction during horizontal rotation, preventing the packaging box 10 from being unable to rotate horizontally along the arc block 31 due to excessive movement in the first direction.

[0038] In addition, in one embodiment, referring to Figure 1 and Figure 2, also includes a first baffle 24 and a second baffle 25, the first baffle 24 and the second baffle 25 are located on the same side above the first conveyor belt 20, the first baffle 24 and the second baffle 25 are arranged on the side away from the rotating device 30, a gap is provided between the first baffle 24 and the second baffle 25, the second roller 22 is aligned with the gap, and the first baffle 24 and the second baffle 25 extend along the first direction.

[0039] It should be noted that the first baffle 24 and the second baffle 25 provide a limit for the package box 10 on the second side of the first conveyor belt 20. The interval between the first baffle 24 and the second baffle 25 is the position where the package box 10 rotates. The interval is set to avoid the package box 10 from being interfered with by the first baffle 24 or the second baffle 25 during the rotation along the arc block 31. The first baffle 24 and the second baffle 25 are parallel to the first direction and the second direction. The first baffle 24 and the second baffle 25 will not hinder the movement of the package box 10 in the first direction.

[0040] In addition, in one embodiment, referring to Figure 1 , further comprising a second conveyor belt 40, the second conveyor belt 40 being located at the discharge end of the first conveyor belt 20, and the conveying direction of the second conveyor belt 40 being the first direction.

[0041] It should be noted that the second conveyor belt 40 is used to transport the boxes 10 that have passed through the first conveyor belt 20. During operation, multiple boxes 10 that have passed through the first conveyor belt 20 are transported to the second conveyor belt 40, which then transports the multiple boxes 10 in a first direction. A transfer pallet comprises a collection of multi-layer boxes 10, and a collection of single-layer boxes 10 comprises multiple boxes 10. By adjusting the conveying speed of the second conveyor belt 40, the multiple boxes 10, which have been oriented, are compactly arranged. The arrangement of the multiple boxes 10 corresponds to the arrangement of the multiple boxes 10 on the collection of single-layer boxes 10.

[0042] In addition, in one embodiment, referring to Figure 1 , the second conveyor belt 40 further includes:

[0043] a third baffle 41, the third baffle 41 being located above a side of the second conveyor belt 40 away from the first conveyor belt 20;

[0044] The push plate 42 and the third baffle 41 are located in a first direction of the push plate 42 . The push plate 42 is perpendicular to the third baffle 41 . The push plate 42 is used to push the packaging box 10 .

[0045] It should be noted that the second conveyor belt 40 conveys multiple boxes 10 along the first direction, the third baffle 41 provides a limit for the boxes 10 in the first direction, and the second conveyor belt 40 continues to work to reduce the distance between the multiple boxes 10 and reduce the space occupied by the multiple boxes 10. The push plate 42 pushes the multiple compactly arranged boxes 10 to the transfer area, so that the multiple boxes 10 become part of the single-layer box 10 collection on the transfer pallet.

[0046] In addition, in one embodiment, referring to Figure 1 , also includes a second sensor 23 and a third sensor 43, the second sensor 23 is located above the first conveyor belt 20, the second sensor 23 is located at one end of the first conveyor belt 20 close to the second conveyor belt 40, the second sensor 23 is electrically connected to the second conveyor belt 40, the third sensor 43 is located above the second conveyor belt 40, the third sensor 43 is located between the push plate 42 and the first conveyor belt 20, and the third sensor 43 is electrically connected to the push plate 42.

[0047] It should be noted that the second sensor 23 can be a beam grating, the light receiver and light emitter of which are fixed on both sides of the first conveyor belt 20. When a package box 10 passes by, the package box 10 blocks the light signal emitted by the light emitter, the light receiver does not receive the light signal, and the beam grating generates an electrical signal.

[0048] It should be noted that the second conveyor belt 40 is in standby state, the second sensor 23 generates an electrical signal and sends it to the second conveyor belt 40, the number of electrical signals received by the second conveyor belt 40 reaches a preset threshold, the second conveyor belt 40 works, and the second conveyor belt 40 transports multiple packaging boxes 10 along the first direction.

[0049] It should be noted that the third sensor 43 is used to detect whether the packaging boxes 10 that need to be pushed to the transfer area are all within the pushing range of the push plate 42. In order to achieve better detection effect, the third sensor 43 is as close to the push plate 42 as possible.

[0050] It should be noted that the third sensor 43 can be a beam grating, the light receiver and light emitter of which are fixed on both sides of the second conveyor belt 40. When a package box 10 passes by, the package box 10 blocks the light signal emitted by the light emitter, the light receiver does not receive the light signal, and the beam grating generates a trigger signal.

[0051] It should be noted that when the second conveyor belt 40 is working, the third sensor 43 starts working, and the third sensor 43 detects that the packaging box 10 passes by, and the third sensor 43 generates a trigger signal. When the third sensor 43 does not generate a trigger signal within the preset time, that is, the packaging boxes 10 to be pushed are all within the pushing range of the push plate 42, the third sensor 43 generates an electrical signal to the push plate 42, and the push plate 42 works, and the push plate 42 pushes multiple packaging boxes 10 to the transfer area.

[0052] In addition, in one embodiment, referring to Figure 1 and Figure 2 The contact surface of the arc block 31 is provided with a plurality of protrusions.

[0053] It should be noted that the protrusion is used to increase the friction between the arc block 31 and the contact surface, so as to facilitate the rotation of the packaging box 10 along the arc block 31.

[0054] It should be noted that when a package 10 is placed on the first conveyor belt 20, as the package 10 passes the first sensor 21, the first sensor 21 generates and transmits an electrical signal to the cylinder 33. The cylinder 33 drives the connecting rod 32 to move the arc block 31 above the first conveyor belt 20. The first conveyor belt 20 drives the package 10 in a first direction, causing the package 10 to abut against the arc block 31 above the first conveyor belt 20. During the abutment between the package 10 and the arc block 31, the arc block 31 provides a contact force perpendicular to the package 10 until the contact surface of the package 10 is parallel to the first direction, completing the horizontal rotation of the package 10. The first conveyor belt 20 conveys the package 10 in the first direction. When the package 10 passes the second sensor 23, the second sensor 23 generates an electrical signal and transmits it to the second conveyor belt 40. When the number of electrical signals received by the second conveyor belt 40 reaches a preset threshold, the second conveyor belt 40 is activated, and the third sensor 43 is activated. The second conveyor belt 40 drives the multiple boxes 10 in a first direction. The third stopper 41 limits the multiple boxes 10 in the first direction, ensuring that the multiple boxes 10 are closely arranged. If the third sensor 43 does not receive a signal from a passing box 10 within a preset time, the third sensor 43 generates an electrical signal and sends it to the push plate 42, which activates the push plate 42 and pushes the multiple, tightly arranged boxes 10 to the transfer area.

[0055] In addition, an embodiment of the present invention further provides a palletizer, comprising the above rotating device.

[0056] It should be noted that the palletizer can be the rotary device itself or other devices that use the rotary device. This embodiment does not limit the specific type of the palletizer, as long as it can use the above-mentioned rotary device.
