Description

Technical Field

[0001] The present invention relates to the technical field of profile production, and particularly relates to a method for loading profiles into a frame. Background Art

[0002] After profiles are produced, they need to be transferred to other places for processing. To facilitate stacking or transportation, the profiles are usually loaded into a material frame after production and then stacked or transported. Loading the profiles into the frame requires neatly stacking the profiles in the material frame, and separating each layer of profiles with partitions or spacers. This can protect the profiles, avoid scratching or collision on the profile surface, and at the same time facilitate stacking and transportation of the profiles together with the material frame.

[0003] The operation of loading profiles into the frame is generally carried out by pure manual or a combination of manual and mechanical methods. For pure manual loading operation, workers need to first place the spacers in the material frame, and then manually place the profiles neatly on the spacers one by one. After laying one layer of profiles, place the spacers again and repeat the operation. The labor intensity of workers is high and the work efficiency is low. For the combined manual and mechanical loading operation, the spacers are usually placed manually and the profiles are placed by machinery. Although the labor intensity of workers is lower than that of pure manual operation, it still limits the improvement of the work efficiency of loading profiles into the frame, and there are also relatively high safety risks in the cooperation between manual and machinery.

[0004] The technical problem to be solved by this application is: how to solve the problems of high labor intensity, low work efficiency and certain potential safety hazards existing in the existing profile loading operation. Summary of the Invention

[0005] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a method for loading profiles into a frame, which can replace manual operation for loading profiles into the frame and has the characteristics of safety and high efficiency.

[0006] The technical solution adopted by the present invention is: a method for loading profiles into a frame, including the following steps:

[0007] S1: Set parameters, set the number of profiles per layer and the number of layers of profiles when the material frame is full.

[0008] S2: Load the spacers, and put the spacers into the spacer storage cavity arranged between two conveyor belts by a manipulator.

[0009] S3: Feed the materials, and convey the corresponding number of profiles per layer onto the conveyor belt.

[0010] S4: Load into the frame, the manipulator grabs the uppermost spacer in the spacer storage cavity, and then transfers the spacer together with the profiles on the conveyor belt into the material frame.

[0011] S5: Detect the number of layers of profiles in the material frame, and determine whether the material frame is full. If so, end the frame loading operation; if not, return to step S3.

[0012] For the profile frame loading method of the present application, mechanical equipment is used to replace manual labor for profile frame loading operations. The separator is loaded by a manipulator, then a single layer of profiles is conveyed above the separator. Next, the manipulator grabs the separator together with the profiles on the conveyor belt, and transfers the separator and profiles into the material frame. Each grab can load one layer of profiles, realizing layer-by-layer profile frame loading operations, improving the efficiency of profile frame loading, saving labor cost input, and at the same time reducing the participation of manual labor in the frame loading operation, which is safer.

[0013] In some embodiments, in step S2, the number of separators loaded into the separator storage cavity each time is the same as the number of separators when the material frame is full.

[0014] Adopting the above technical solution can ensure that the number of separators loaded into the separator storage cavity each time is equal to the number of separators when the material frame is full, so as to avoid the lack of the number of separators affecting the profile frame loading operation or too many separators affecting the next separator loading.

[0015] In some embodiments, a number of positioning grooves corresponding to the separators are arranged at intervals in the material frame, and the positioning grooves correspond to the separator storage cavities one by one.

[0016] Adopting the above technical solution ensures the accuracy and consistency of profile frame loading.

[0017] In some embodiments, before step S5 returns to step S3, the following steps are further included:

[0018] S6: Check the remaining amount of profiles, and determine whether the remaining amount of profiles is greater than the number of profiles in a single layer. If so, return to step S3; if not, execute step S7;

[0019] S7: Remaining material processing, conveying all the remaining profiles onto the conveyor belt;

[0020] S8: Remaining material frame loading, the manipulator grabs the lowermost separator in the separator storage cavity, then transfers all the remaining separators together with the profiles on the conveyor belt into the material frame, and then ends the frame loading operation.

[0021] With the above technical solution, ideally, each batch of profiles can fill the corresponding number of material frames. However, due to the inevitable production of defective products during the production process, after removing the defective products, the total number of qualified profiles is less than the total amount of profiles that can fill the corresponding number of material frames. If the excess spacers are not removed, it will affect the frame loading operation of the next batch of profiles, and profiles from different batches cannot be mixed, otherwise it will affect subsequent processing. Therefore, when the remaining amount of profiles is not enough to fill the material frame, it is necessary to load the profiles and the remaining spacers into the material frame together when loading the last layer of profiles to ensure the normal operation of the frame loading operation of the next batch of profiles.

[0022] In some embodiments, when each profile is conveyed to the conveyor belt, the ends of the profiles are aligned and arranged at intervals in parallel.

[0023] With the above technical solution, arranging the profiles neatly can make the force on the profiles transferred on the conveyor belt uniform, and can ensure that they can be accurately loaded into the material frame.

[0024] In some embodiments, a spacer lifting mechanism is provided on one side of the spacer storage cavity. In step S4, the spacer lifting mechanism lifts the uppermost spacer in the storage cavity to facilitate the manipulator to grab it.

[0025] With the above technical solution, when there are multiple spacers stored in the spacer storage cavity, adjacent spacers are in contact with each other, which is convenient for the manipulator to grab. Therefore, it is necessary to use the spacer lifting mechanism to lift the uppermost spacer and separate it from the lower spacers to facilitate grabbing.

[0026] In some embodiments, in step S8, the spacer lifting mechanism stops working.

[0027] With the above technical solution, when loading the remaining materials into the frame, the manipulator needs to take away all the remaining spacers. Therefore, the manipulator will descend to the bottom of the spacer storage cavity to grab the lowermost spacer. Therefore, it is necessary for the spacer lifting mechanism to stop working to avoid interference with the manipulator.

[0028] In some embodiments, the jaws of the manipulator grab the spacer by holding the bottoms of both ends of the spacer.

[0029] With the above technical solution, this can prevent the spacer from being bent and deformed, making the transfer of the spacer and the profiles falling on the spacer more stable.

[0030] In some embodiments, a label is provided on the material frame, and the information recorded on the label includes the batch number and quantity of the loaded profiles.

[0031] With the above technical solution, it is convenient to identify the batch of profiles in subsequent processes, and it is convenient for the unloading manipulator to grab the profiles according to the number of loaded layers of profiles in the material frame, reducing the empty stroke or avoiding interference between the unloading manipulator and the spacers.

[0032] In some embodiments, counters are provided on both the conveyor belt and the robotic arm.

[0033] With the above technical solution, the counter on the conveyor belt is used to record the number of profiles on the conveyor belt, and the counter on the robotic arm is used to count the number of times the robotic arm grabs, so as to calculate the number of layers of profiles loaded in the material box.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. When the number of an element is referred to as having "a plurality", it can be any number of two or more. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this invention belongs. The terms used in the description of the present invention herein are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0042] Please refer to Figure 1 and Figure 2 , which is a method for framing profiles in a preferred embodiment of the present invention, comprising the following steps:

[0043] S1: Set parameters, set the number of profiles per layer and the number of layers of profiles when the material frame is full.

[0044] S2: Load spacers. Use a manipulator to put spacers into the spacer storage cavity 20 arranged between two conveyor belts 10.

[0045] S3: Feed materials. Convey the corresponding number of profiles per layer onto the conveyor belt 10.

[0046] S4: Frame. The manipulator grabs the uppermost spacer in the spacer storage cavity 20, and then transfers the spacer together with the profiles on the conveyor belt 10 into the material frame 30.

[0047] S5: Detect the number of layers of profiles in the material frame 30, and judge whether the material frame 30 is full. If so, end the framing operation; if not, return to step S3.

[0048] In the method for framing profiles of the present application, mechanical equipment is used to replace manual labor for the profile framing operation. The manipulator is used to load spacers, then convey a single-layer quantity of profiles above the spacers, and then the manipulator grabs the spacer together with the profiles on the conveyor belt 10 and transfers the spacer and the profiles into the material frame 30. Each grab can load one layer of profiles, realizing the layer-by-layer profile framing operation, improving the efficiency of profile framing, saving the input of labor costs, and at the same time reducing the participation of manual labor in the framing operation, making it safer.

[0049] In step S2, the number of spacers loaded into the spacer storage cavity 20 each time is the same as the number of spacers when the material frame 30 is full. This can ensure that the number of spacers loaded into the spacer storage cavity 20 each time is equal to the number of spacers when the material frame 30 is full, so as to avoid the influence on the profile framing operation due to too few spacers or the influence on the next spacer loading due to too many spacers.

[0050] Furthermore, a number of positioning grooves 31 corresponding to the spacers are arranged at intervals in the material frame 30, and the positioning grooves 31 correspond to the spacer storage cavity 20 one by one. Such a setting ensures the accuracy and consistency of profile framing. At the same time, when the manipulator frames, only horizontal movement is required, shortening the travel of the manipulator to improve efficiency, and at the same time reducing the framing difficulty.

[0051] To ensure that the number of spacers loaded into the spacer storage cavity 20 each time is the same as the number of spacers that can fill the material frame 30, when loading the spacers, the manipulator takes out the spacers from the positioning grooves 31 in the material frame 30 and then fills the spacers into the spacer storage cavity 20, that is, the spacers follow the rotation of the material frame 30. This can ensure that the number of spacers remains consistent, while saving the space and facilities for separately equipped spacer storage.

[0052] In one embodiment, before step S5 returns to step S3, the following steps are further included:

[0053] S6: Check the remaining amount of profiles, and determine whether the remaining amount of profiles is greater than the number of single-layer profiles. If so, return to step S3; if not, execute step S7;

[0054] S7: Scrap processing, conveying all the remaining profiles onto the conveyor belt 10;

[0055] S8: Scrap framing, the manipulator grabs the lowermost spacer in the spacer storage cavity 20, and then transfers all the remaining spacers together with the profiles on the conveyor belt 10 into the material frame 30, and then ends the framing operation.

[0056] In an ideal state, each batch of profiles can fill the corresponding number of material frames 30. However, due to the inevitable generation of defective products during the production process, after removing the defective products, the total number of qualified profiles is less than the total amount of profiles that can fill the corresponding number of material frames 30. And if the excess spacers are not removed, it will affect the framing operation of the next batch of profiles, and profiles of different batches cannot be mixed, otherwise it will affect subsequent processing. Therefore, when the remaining amount of profiles is not enough to fill the material frame 30, it is necessary to load the remaining profiles and the remaining spacers into the material frame 30 together when loading the last layer of profiles to ensure the normal operation of the framing operation of the next batch of profiles.

[0057] Preferably, when each profile is conveyed to the conveyor belt 10, the ends of the profiles are aligned and arranged at intervals in parallel. Arranging the profiles neatly can make the force on the profiles transferred on the conveyor belt 10 uniform, and can ensure that they can be accurately loaded into the material frame 30.

[0058] Furthermore, a aligning mechanism can be provided upstream of the conveyor belt 10 or on the conveyor belt 10 to adjust the posture of the profiles so that when the manipulator grabs them, the arrangement of the profiles meets the requirements.

[0059] In one embodiment, a spacer lifting mechanism 40 is provided on one side of the spacer storage cavity 20. In step S4, the spacer lifting mechanism 40 lifts the uppermost spacer in the storage cavity to facilitate the manipulator to grasp it. When there are multiple spacers stored in the spacer storage cavity 20, adjacent spacers are in contact with each other to facilitate the manipulator to grasp them. Therefore, it is necessary to use the spacer lifting mechanism 40 to lift the uppermost spacer and separate it from the lower spacers to facilitate grasping.

[0060] To prevent the spacer lifting mechanism 40 from interfering with the manipulator's grasping, in addition to being able to lift vertically, the spacer lifting mechanism 40 also needs to have the ability to move horizontally.

[0061] Further, in step S8, the spacer lifting mechanism 40 stops working. When loading the remaining materials into the frame, the manipulator needs to take away all the remaining spacers. Therefore, the manipulator will descend to the bottom of the spacer storage cavity 20 to grasp the lowermost spacer. Therefore, it is necessary for the spacer lifting mechanism 40 to stop working to avoid interference with the manipulator.

[0062] Preferably, in order to facilitate the manipulator to pick and place spacers into and from the spacer storage cavity 20, an avoidance groove corresponding to the manipulator's jaw is provided on the side wall of the spacer storage cavity 20.

[0063] Preferably, the manipulator's jaw grasps the spacer by supporting the bottoms of both ends of the spacer. This can prevent the spacer from bending and deforming, making the transfer of the spacer and the profiles falling on the spacer more stable.

[0064] Further, the jaws on the manipulator should correspond one-to-one with the positioning grooves 31 on the spacer storage cavity 20 and the material frame 30.

[0065] In one embodiment, a label is provided on the material frame 30. The information recorded on the label includes the batch and quantity of the loaded profiles. It can facilitate the identification of the profile batch in subsequent processes and facilitate the unloading manipulator to grasp the profiles according to the loading layers of the profiles in the material frame 30, reducing the empty travel or avoiding interference between the unloading manipulator and the spacers.

[0066] Preferably, in order to facilitate reading the information, the label is preferably an electronic label.

[0067] In one embodiment, counters are provided on both the conveyor belt 10 and the manipulator. The counter on the conveyor belt 10 is used to record the number of profiles on the conveyor belt 10, and the counter on the manipulator is used to count the number of times the manipulator grasps, so as to calculate the number of layers of profiles loaded in the material frame 30.

[0068] For ease of understanding, the profile loading method of the present application will be introduced below by way of example with specific numerical values, but it is not limited to these values.

[0069] In step S5, it is determined by the controller whether the material frame is full, and in step S6, it is determined whether the remaining amount of profiles is greater than the number of profiles in a single layer. Optionally, the controller is a PLC controller or a computer.

[0070] It should be noted that before the frame loading operation, the number of profiles in each layer and the number of layers of profiles when the material frame is full need to be determined. Therefore, the number of profiles in each layer and the number of layers of profiles when the material frame is full need to be set before the frame loading operation starts. The above values can be set according to actual requirements.

[0071] As Figure 3 shown, it is assumed that when the material frame 30 is full, it can hold 16 layers of profiles, and there are 15 profiles in each layer. That is, when the material frame 30 is full, a total of 240 profiles can be loaded. This is the normal full state of the material frame 30. However, due to the existence of defective products, after removing the defective products, the number of qualified profiles in this batch will be less than 240. As Figure 4 shown, it is assumed that the qualified rate of the profiles in this batch is 85%, that is, 204 profiles. After filling 13 layers, there are 9 profiles remaining. That is, the material frame 30 can hold at most 14 layers in this batch. Therefore, when loading the 14th layer, the manipulator needs to load the remaining 3 spacers and 9 profiles into the material frame 30 together, and then end the frame loading operation.

[0072] Finally, it should be noted that the above are only preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
