Technical Field

[0001] The utility model relates to the field of electromechanical technology, in particular to an automatic profile collecting roller conveyor. Background Art

[0002] Profiles are a type of material widely used in many fields such as industry, construction, and display. Steel sections are strip-shaped steel with specific cross-sectional shapes and sizes.

[0003] In civil air defense applications, various steel sections are processed into various lengths and shapes. After being cut by plasma and laser cutting machines, these sections, large and small, fall directly onto the ground or onto a platform, requiring personnel to enter the cutting area to retrieve them. This increases safety risks. The cutting equipment must be stopped while personnel retrieve the material, and errors in sorting and counting the sections are common, reducing production efficiency. Falling steel sections not only damage contact surfaces but also deform them. Later corrections increase labor costs, and the scrap material is scattered throughout the cutting area, making it difficult for personnel to collect and clean it.

[0022] Example, by Figure 1-7 It is given that the profile automatic collection roller machine includes a main roller conveyor frame 2, and multiple groups of main roller conveyor device brackets 4 are fixed at the front and back of the bottom of the main roller conveyor frame 2 for support. The bottom of each group of main roller conveyor device brackets 4 is threadedly connected with a threaded foot rod. The main roller conveyor frame 2 is rotatably connected to multiple conveying rollers 21, and the middle part of the main roller conveyor frame 2 is rotatably connected to an active roller 7. The side end of the main roller conveyor frame 2 is fixed with a mounting frame, and the top of the mounting frame is fixed with a motor 5 and a reducer 6. After the output of the motor 5, it is connected to the reducer 6 for transmission. The output shaft of the reducer 6 is rotatably connected to the active roller 7. A roller chain 22 is connected between the active roller 7 and multiple conveying rollers 21. Grating belts 8 are installed on both sides of the top edge of the main roller conveyor frame 2. There is a slope sliding device 1 on the lower side of the main roller conveyor frame 2, and a roller machine flip device 3 is provided in contact with the side end of the main roller conveyor frame 2.

[0023] The profile automatic collection roller conveyor is controlled by an external PLC system. Figure 6As shown, the PLC system controls the operation of the motor 5, which drives the active roller 7 to rotate through the speed reducer 6, and the active roller 7 drives multiple conveying rollers 21 to rotate through the roller chain 22, and conveys the processed profiles to the roller machine flip device 3; when the profiles of specific shapes are cut onto the main roller conveyor frame 2, smaller waste materials are mixed in the profiles, and the gaps between the multiple conveying rollers 21 cause the waste materials to fall onto the slope sliding device 1 during transportation and be guided to slide down. A collection trough is placed at the lowest position of the slope sliding device 1 to collect the waste materials, and the cut profiles are sent to the roller machine flip device 3; moreover, the cut profiles have a grating belt 8 to sense their transportation process during operation. When the profiles are stuck in a certain position and do not move for a long time during transportation, the grating belts 8 distributed on the main roller conveyor frame 2 sense the movement and send a signal to the external PLC system, thereby stopping the motor 5 and making an alarm.

[0024] In this embodiment, the slope sliding device 1 includes a trough plate 12, and two groups of brackets 11 of different heights are fixedly connected on the front and rear sides of the bottom of the trough plate 12 through angle steel for inclined support. The bottoms of the two groups of brackets 11 are threadedly connected with threaded foot rods. Two baffles 13 are fixed on the front and rear sides of the top of the trough plate 12 through angle steel. A plurality of rollers 14 are rotatably connected to the middle part of the trough plate 12. When the waste falls onto the inclined trough plate 12, the waste automatically slides down due to the inclination of the trough plate 12 and the assistance of the plurality of rollers 14, and is intercepted by the baffle 13 so that the waste falls into the collection trough for collection.

[0025] In this embodiment, the roller conveyor flipping device 3 includes a second bracket 31, which is L-shaped and has threaded foot rods threadedly connected to the front and back of the bottom. Multiple sets of rotating plate devices 32 are fixedly installed on the front side of the top of the second bracket 31. The bottom of the rear of the second bracket 31 is rotatably connected to multiple sets of lifting cylinders 36. The multiple sets of lifting cylinders 36 correspond one-to-one to the multiple sets of rotating plate devices 32. The tops of the multiple sets of lifting cylinders 36 are rotatably connected to connecting support plates 33. The connecting support plates 33 are in contact with and supported by the multiple sets of rotating plate devices 32. The middle part of the connecting support plate 33 is rotatably connected to multiple weight sensing switch rollers 34. The top edge of the connecting support plate 33 is located at the position of the lifting cylinder 36 and a plurality of proximity switches 37 are installed. The weight sensing switch roller 34 is provided with a gravity sensing switch to sense gravity.

[0026] Specifically, the cut profile is input onto the connecting support plate 33 and contacts multiple weight-sensing switch rollers 34. The connecting support plate 33 is kept stable by multiple rotating plate devices 32. The proximity switch 37 on one side of the connecting support plate 33 and the gravity-sensing switch set in the weight-sensing switch roller 34 sense whether the profile weight is qualified. That is, the profile moves onto the weight-sensing switch roller 34, which presses it slightly downward, touching the gravity switch and transmitting a high-frequency electric signal. When cutting two profiles of different lengths, if the weight of one length does not meet the requirements, the gravity-sensing switch will not output. This type of steel profile is assisted by the multiple weight-sensing switch rollers 34 and rolled to the collection rack at the end. When the weight of one length meets the requirements, the gravity-sensing switch sends a signal to the external PLC system. The PLC control system synchronously controls the operation of the air pumps connected to the multiple cylinders. The multiple cylinders supply air to cause the connecting support plate 33 to tilt at a certain angle, so that the profile slides down and slides to the collection rack on the side at a certain angle and time. After completion, the cylinders are controlled to retract and drive the connecting support plate 33 back to its original position.

[0027] Among them, a limit switch 35 is fixed to the side end of each set of rotating plate devices 32. The limit switch 35 includes a contact system seat fixed to the side end of the rotating plate device 32 and an operating head installed on the bottom side of the connecting support plate 33. During the return process of the connecting support plate 33, the operating head is inserted into the contact system seat and sends a signal to the PLC system, thereby determining the return of the connecting support plate 33.

[0028] Among them, the rotating plate device 32 includes a flip cylinder 321 fixed on the top of the bracket 2 31. A bearing seat 322 is rotatably installed in the flip cylinder 321 to contact the connecting support plate 33 for support. The flip cylinder 321 can support the connecting support plate 33 and also assist the profile to slide down.

[0029] In this embodiment, an inductive counting device is installed on the roller conveyor turning device to count the number of products. When the required number is reached, loading is stopped, which makes it convenient for personnel to perform batch summarization and counting.

[0030] Working principle:

[0031] The profile automatic collection roller conveyor is controlled by an external PLC system. Figure 6 As shown, the PLC system controls the motor 5 to work, which drives the active roller 7 to rotate through the reducer 6, and the active roller 7 drives the multiple conveyor rollers 21 to rotate through the roller chain 22, and conveys the processed profiles to the roller conveyor turnover device 3;

[0032] When the profiles of specific shapes are cut onto the main roller conveyor frame 2, smaller waste materials are mixed in the profiles. The gaps between multiple conveying rollers 21 cause the waste materials to fall onto the slope slide device 1 during the conveying process and be guided to slide down. A collection trough is placed at the lowest position of the slope slide device 1 to collect the waste materials, and the cut profiles are sent to the roller conveyor flip device 3.

[0033] Moreover, during the operation of the cut profile, the grating belt 8 senses its transportation process. When the profile is stuck in a certain position and does not move for a long time during transportation, the grating belt 8 spread over the main roller conveyor frame 2 senses the movement and sends a signal to the external PLC system, thereby stopping the motor 5 and issuing an alarm.

[0034] When the waste falls onto the inclined trough plate 12, the waste automatically slides down due to the inclination of the trough plate 12 and the assistance of multiple rollers 14, and is intercepted by the baffle 13, so that the waste falls into the collection trough for collection.

[0035] The cut profile is fed onto a connecting support plate 33, where it contacts multiple weight-sensing rollers 34. The connecting support plate 33 is maintained stable by multiple rotating plate devices 32. A proximity switch 37 on one side of the connecting support plate 33 and a gravity-sensing switch within the weight-sensing roller 34 sense the profile's weight. Specifically, the profile moves onto the weight-sensing roller 34, forcing it to move slightly downward. This contact triggers a high-frequency signal from the gravity-sensing switch. When cutting two profiles of different lengths, if one length does not meet the weight requirement, the gravity-sensing switch will not output a signal. This section of steel is then rolled and conveyed to a collection rack at the end of the machine using the weight-sensing rollers 34. When one length meets the weight requirement, the gravity-sensing switch sends a signal to an external PLC system. The PLC control system synchronously controls the operation of air pumps connected to multiple cylinders. These cylinders supply air, causing them to extend and tilt the connecting support plate 33 to a certain angle, allowing the profile to slide downward, allowing it to slide to the side collection rack at a predetermined angle and time. Upon completion, the cylinders are controlled to retract, returning the connecting support plate 33 to its original position. This return is confirmed by a travel switch 35.
