Description

Technical Field

[0001] The present application relates to the field of sorting equipment, and in particular to an equipment for sorting items in a carrier. Background Art

[0002] The application of automated sorting by robots is becoming more and more widespread. Current sorting technology usually loads a large number of items to be sorted into a carrying box, and then uses an industrial camera installed above the carrying box to read the barcode or QR code of an item in the carrying box and locate and mark the item. The equipment automatically calculates the required movement distance of the production robot and transmits it to the controller. The controller controls the robot to work according to the calculation results and successfully grabs and takes away the corresponding items and places them in the corresponding compartment according to the read product category results. This process is repeated to complete the sorting of many items.

[0003] However, because a unified robotic arm is used to grasp items, sufficient space must be left around the items to be grasped. If there is insufficient grasping space, the robotic arm cannot properly grasp and sort the items. Secondly, sometimes the barcode and QR code on the items are not facing the industrial camera, resulting in the industrial camera failing to read the item information and unable to properly grasp and sort the items. This requires manual intervention to organize the items, which in turn interrupts the automated sorting process and makes it difficult to improve sorting efficiency. Utility Model Content

[0035] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0036] An embodiment of the present application discloses a device for organizing items in a carrier.

[0037] Reference Figure 1-Figure 4 ,

[0038] A device for arranging items in a carrier, comprising:

[0039] Carrier 1, used to carry a number of items to be sorted;

[0040] A supporting platform 2, on which the carrier 1 is placed;

[0041] A lifting drive mechanism 3 is used to drive the platform 2 to rise or fall along the Z-axis direction;

[0042] A limiting mechanism 4 is provided on the support platform 2 and is used to limit the carrier 1 and prevent the carrier 1 from moving along the X-axis direction;

[0043] The vibration mechanism 5 is arranged below the supporting platform 2. The vibration mechanism 5 includes a mounting platform 51, a vibration motor 52, and several vibration components 53. The vibration motor 52 is arranged on the mounting platform 51. The vibration component 53 is rotatably arranged on the mounting platform 51. The vibration component 53 includes a rotating shaft 532 and several swinging components 533. The rotating shafts 532 of the several vibration components 53 are arranged parallel to each other in the same horizontal plane. The output end of the vibration motor 52 is transmission-connected to one of the rotating shafts 532. The rotating shafts 532 are transmission-connected by belts or chains 531. The swinging component 533 includes a swing arm 5331 at one end of which is arranged on the rotating shaft 532 and a roller 5332 rotatably arranged on the other end of the swing arm 5331. The axial direction of the roller 5332 is parallel to the rotating shaft 532. When the rotating shaft 532 drives the roller 5332 to move to the highest point, the wheel surface of the roller 5332 presses the lower surface of the carrier 1 upward.

[0044] During the actual use of the present application, a number of products to be sorted with barcodes or QR codes are placed in the carrier 1, and then the carrier 1 is placed on the support platform 2. The lifting drive mechanism 3 drives the support platform 2 to rise or fall, and the distance between the lower surface of the carrier 1 and the vibration mechanism 5 is adjusted to an optimal value. The limiting mechanism 4 is started in the X-axis direction to limit the carrier 1, so that the carrier 1 cannot move along the X-axis direction during the vibration process. The vibration mechanism 5 works, the vibration motor 52 drives the rotating shaft 532 to rotate, the rotating shaft 532 drives the plurality of swing arms 5331 to rotate, and the outer end of the swing arm 5331 drives the roller 5332 to make a circular motion relative to the rotating seat. When the roller 5332 moves to the highest point, the wheel surface of the roller 5332 contacts the lower surface of the carrier 1 and presses the carrier 1 upward. Under the action of the upward squeezing force, the carrier 1 will vibrate back and forth in the Z-axis direction, thereby driving the products in the carrier 1 to shake and flip, so that the surface of the product containing the barcode or QR code is adjusted to an upward posture and enough space is formed around the product for the robot to grasp, so as to organize the items in the carrier. Then, the robot of the sorting equipment can directly grab the identified products and sort them, and so on. This ensures that there is no need for manual intervention to arrange the position of the products on the carrier 1 and the sorting work can be carried out continuously, thereby improving the sorting efficiency.

[0045] Reference Figure 3 The angles between the length directions of the swing arms 5331 and the horizontal plane are different, thereby ensuring that the upward squeezing of the carrier 1 by the rollers 5332 is performed asynchronously, thereby effectively increasing the frequency and amplitude of the vibration of the carrier 1, improving the sorting efficiency of the products in the carrier 1, and thus improving the sorting efficiency.

[0046] Reference Figure 3The vibration component 53 is divided into two groups. One end of the rotating shaft 532 is connected to a bearing seat 5333, and the bearing seat 5333 is arranged on the mounting platform 51. The other end of the rotating shaft 532 is connected to a pulley 54. The belt is connected between the two pulleys 54 of the two rotating shafts 532. Specifically, the number of swing arms 5331 corresponding to each rotating shaft 532 is two, and the corresponding rollers 5332 are at least four. The four rollers 5332 correspond to the four corners of the lower surface of the extrusion carrier 1, respectively, thereby maximizing the amplitude of the vibration of the carrier 1 and improving the efficiency of product sorting in the carrier 1.

[0047] Reference Figure 3 The side surface of the box is provided with a barcode or a QR code, and the mounting platform 51 is provided with a code reader 6 for reading the barcode or QR code of the box. Therefore, the machine can automatically read the product model information in the carrier 1 through the code reader 6 and quickly match the corresponding vibration parameters. The lifting drive mechanism 3 drives the supporting platform 2 to rise or fall, and adjusts the distance between the lower surface of the carrier 1 and the vibration mechanism 5 to the optimal value. At the same time, the vibration motor 52 is matched and controlled within the optimal speed range.

[0048] Reference Figure 3 The limiting mechanism 4 includes a clamping assembly 42 and a first clamping member 41 arranged alternately along the X-axis direction. The clamping assembly 42 includes two slide rails 421, two sliding seats 422, a connecting seat 423, a second clamping member 424 and a clamping driving member 425. The two slide rails 421 are arranged parallel to each other on the mounting table 51. The two sliding seats 422 can be slidably arranged on the two slide rails 421 along the X-axis direction. The connecting seat 423 is connected between the two sliding seats 422. The second clamping member 424 is arranged on the The connecting seat 423, the clamping driving member 425 is used to drive the sliding seat 422 to slide back and forth along the slide rail 421, the first clamping member 41 is used to clamp and limit the side surface of the carrier 1 along the X-axis direction, and the second clamping member 424 is used to clamp and limit the other side surface of the carrier 1 along the X-axis direction. Specifically, the first clamping member 41 is arranged on the supporting platform 2, and the first clamping member 41 and the second clamping member 424 are respectively located on the opposite sides of the carrier 1 along the X-axis direction.

[0049] Reference Figure 3The clamping drive component 425 includes a clamping motor 5251, a rocking arm 4252 and a connecting rod 4253. The clamping motor 5251 is arranged on the mounting platform 51, one end of the rocking arm 4252 is connected to the output end of the clamping motor 5251, one end of the connecting rod 4253 is hinged to the connecting seat 423, and the other end of the connecting rod 4253 is hinged to the other end of the rocking arm 4252. Therefore, the clamping motor 5251 rotates, driving the rocking arm 4252 to swing in the horizontal plane, and then the outer end of the rocking arm 4252 drives the connecting rod 4253 to move and drive the sliding seat 422 to slide relative to the slide rail 421, and then drives the second clamping member 424 to approach the carrier 1 and cooperate with the first clamping member 41 to clamp the carrier 1 to complete the restriction of the carrier 1 in the X-axis direction. When the clamping motor 5251 is reversed, the restriction on the carrier 1 is contacted.

[0050] Reference Figure 2 The platform 2 is provided with an adjustment mechanism 7 for driving the carrier 1 to move along the Y-axis direction. The adjustment mechanism 7 includes a plurality of support rollers 71 and an adjustment drive member. The plurality of support rollers 71 are alternately arranged on the platform 2 along the Y-axis direction. The adjustment drive member is used to drive the plurality of support rollers 71 to roll. The carrier 1 is placed on the roller surface of the plurality of support rollers 71. The clamping end of the second clamping member 424 passes between two adjacent support rollers 71. Specifically, the sorting device is provided with an offset sensor for sensing whether the position of the carrier 1 is cheap. The offset sensor is located above the carrier 1 and is electrically connected to the controller signal. During the vibration of the carrier 1, the fixture may move a certain distance along the Y-axis direction. When the offset sensor senses that the position of the carrier 1 is offset, the controller controls the adjustment drive member to work, drive the support rollers 71 to rotate, and thus send the carrier 1 back to the correct position.

[0051] Reference Figure 1 and 2 , also includes a frame 8, the lifting drive mechanism 3 includes a linear module 31 and an induction switch 32 for controlling the maximum output stroke size of the linear module 31, the linear module 31, the induction switch 32 and the vibration mechanism 5 are all arranged on the frame 8, and the support platform 2 is arranged at the output end of the linear module 31.

[0052] A controller is also included, and the vibration motor 52, the code reader 6, the clamping motor 5251, the adjustment drive component, the linear module 31, and the induction switch 32 are all electrically connected to the controller.

[0053] The implementation principle of the device for sorting items in a carrier according to the embodiment of the present application is as follows: in the actual use process of the present application, a plurality of products to be sorted with bar codes or QR codes are placed in the carrier 1, and then the carrier 1 is placed on the support platform 2. The lifting drive mechanism 3 drives the support platform 2 to rise or fall, and the distance between the lower surface of the carrier 1 and the vibration mechanism 5 is adjusted to an optimal value. The limiting mechanism 4 is activated in the X-axis direction to limit the carrier 1 so that the carrier 1 cannot move along the X-axis direction during the vibration process. The vibration mechanism 5 works, the vibration motor 52 drives the rotating shaft 532 to rotate, the rotating shaft 532 drives the plurality of swing arms 5331 to rotate, and the outer ends of the swing arms 5331 drive the rollers 5 332 makes circular motion relative to the rotating seat. When the roller 5332 moves to the highest point, the wheel surface of the roller 5332 contacts the lower surface of the carrier 1 and squeezes the carrier 1 upward. Under the action of the upward squeezing force, the carrier 1 will vibrate back and forth in the Z-axis direction, thereby driving the product in the carrier 1 to shake and flip, so as to adjust the surface of the product containing the barcode or QR code to an upward posture and form enough space around the product for the robot to grasp, so as to organize the items in the carrier. Then, the robot of the sorting equipment can directly grab the identified products and sort them, and so on.
