Description

Technical Field

[0001] The present invention belongs to the technical field of display cabinet production, and in particular relates to a display cabinet side panel sheet metal component unloading system and unloading method. Background Art

[0002] In the production of existing display cabinet side panel sheet metal parts, automatic sheet metal forming lines are usually used, and the production adopts a one-out-two method (that is, two left and right side panels are cut from a single plate). However, when the side panel sheet metal parts are off the line, a single side panel off-line storage method is usually adopted. That is, the left and right side panels are taken out separately and placed on different turnover tooling vehicles through manual picking and placing. However, this single side panel off-line storage method is labor-intensive and prone to process quality problems such as bumps and scratches during manual handling. Moreover, when the left and right side panels are placed on different turnover tooling vehicles, they are easily placed in the wrong place or taken out of the right place, resulting in the confusion of the side panel sheet metal parts in the subsequent production process. At the same time, the left and right side panels of different display cabinet models need to be placed separately, which is also easy to cause confusion of the side panel sheet metal parts when switching production of similar models. In addition, the manual picking and placing off-line method cannot achieve automatic distribution production with the next process. Therefore, how to achieve the complete set of sheet metal parts of the display cabinet side panels off the production line to avoid confusion in subsequent production is a technical problem that urgently needs to be solved. Summary of the Invention

[0003] In response to the above-mentioned shortcomings in the existing storage of single side panel sheet metal parts for display cabinets, the present invention provides a display cabinet side panel sheet metal part off-line system and off-line method, which can realize the complete off-line of the left and right side panels of the display cabinet, effectively avoiding the problem of mixed use of side panel sheet metal parts in subsequent production.

[0023] The manipulator moves to the top of the side panel placement platform, picks up the first side panel placed on the side panel placement platform with the manipulator, and moves the manipulator with the first side panel toward the side panel placement position. During the movement, the manipulator rotates the first side panel 180° about a plumb line as an axis. When the manipulator moves to the top of the side panel placement position, the manipulator stacks the rotated first side panel on the second side panel placed on the side panel placement position.

[0024] The stacked first side panels and the second side panels are transported by a blanking conveyor line.

[0025] Compared with the prior art, the advantages and positive effects of the present invention are:

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0052] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0053] As attached Figure 1 As shown, in an exemplary embodiment of the display cabinet side panel sheet metal unloading system of the present invention, the display cabinet side panel sheet metal unloading system includes a conveyor roller line 1, a side panel placement platform 2, a turning device 3, a translation conveying device 4, a manipulator 5 and a material unloading conveying line 7; Figure 2 As shown, the conveyor roller line 1 is connected to the production end of the automatic sheet metal forming line to convey the first side panel 8 and the second side panel 9 that are successively off the line (it should be noted that the first side panel 8 and the second side panel 9 are two side panels cut out of a plate on the automatic sheet metal forming line in pairs, wherein one is the left panel and the other is the right panel. The off-line order of the left panel and the right panel is not limited here. Only the first side panel 8 represents the side panel that comes off the line first and the second side panel 9 represents the side panel that comes off the line later). The conveyor roller line 1 is provided with a second side panel parking position 102 for parking the second side panel 9 and a first side panel parking position 101 for parking the first side panel 8 in sequence along its conveying direction; as shown Figure 4 As shown, the side panel placement platform 2 is arranged on one side of the conveyor roller line 1 and is opposite to the first side panel parking position 101; Figure 4 、 Figure 6 and Figure 7 As shown, the turning device 3 is arranged between the first side panel parking position 101 of the conveyor roller line 1 and the side panel placement platform 2, and is used to turn the first side panel 8 parked on the first side panel parking position 101 by 180 degrees with a horizontal line parallel to the conveying direction of the conveyor roller line 1 as the axis and then place it on the side panel placement platform 2; Figure 4 、 Figure 10 and Figure 11As shown, the translation conveying device 4 and the side panel placement platform 2 are located on the same side of the conveying roller line 1, and the conveying direction of the translation conveying device 4 is perpendicular to the conveying direction of the conveying roller line 1. One end of the translation conveying device 4 in the conveying direction extends to below the second side panel parking position 102 of the conveying roller line 1, and the other end of the translation conveying device 4 in the conveying direction is provided with a side panel placement position 401. The translation conveying device 4 is used to convey the second side panel 9 parked on the second side panel parking position 102 to the side panel placement position 401; as shown Figure 1 As shown, the robot 5 reciprocates between the side panel placement platform 2 and the side panel placement position 401, and is used to pick up the first side panel 8 placed on the side panel placement platform 2, and rotate the first side panel 8 180° with a plumb line as the axis and then stack it on the second side panel 9 placed on the side panel placement position 401; one end of the unloading conveyor line 7 is connected to one end of the translation conveying device 4 provided with the side panel placement position 401, and is used to transport the stacked first side panel 8 and the second side panel 9.

[0054] The above-mentioned display cabinet side panel sheet metal unloading system is configured to convey the first side panel 8 and the second side panel 9 that have been unloaded from the automatic sheet metal forming line in succession by setting a conveyor roller line 1, and to park the first side panel 8 and the second side panel 9 at the first side panel parking position 101 and the second side panel parking position 102 respectively. The first side panel 8 parked at the first side panel parking position 101 is flipped 180 degrees by the provided flipping device 3 and then buckled on the side panel placement platform 2 provided on one side of the conveyor roller line 1. The second side panel is placed at the parking position 102 by the provided translation conveying device 4. The parked second side panel 9 is translated to the side panel placement position 401 at the end of the translation conveyor 4. The manipulator 5 is provided to pick up the first side panel 8 on the side panel placement platform 2, rotate it 180°, and then stack it on the second side panel 9 at the side panel placement position 401. This allows the two sets of side panels produced by the automatic sheet metal forming line to be stacked in a relative manner. The unloading conveyor line 7 is then used to realize the complete off-line of the side panels, effectively avoiding the problem of mixed use of side panel sheet metal parts in subsequent production and reducing defective products caused by mixed use of side panel sheet metal parts. Moreover, the use of the above-mentioned display cabinet side panel sheet metal off-line system instead of the manual off-line method of transporting side panel sheet metal parts can save labor and significantly improve production efficiency.

[0055] In order to facilitate the first side panel 8 and the second side panel 9 to be parked at the first side panel parking position 101 and the second side panel parking position 102 respectively, as shown in FIG. Figure 2 and Figure 3As shown, a first stopper 12 is provided at the front end of the first side panel parking position 101 and the front end of the second side panel parking position 102 on the conveyor roller line 1. The first stopper 12 is located between adjacent rollers 11 of the conveyor roller line 1 and can be raised and lowered relative to the conveyor roller line 1. When the first stopper 12 is raised, it blocks the conveyed objects on the conveyor roller line 1. When the first stopper 12 is lowered, the conveyed objects are conveyed along the conveyor roller line 1. It should be noted that the front in the conveying direction of the conveyor roller line 1 is referred to as the front. During the transportation of the first side panel 8 and the second side panel 9 on the conveyor roller line 1, the first side panel 8 and the second side panel 9 can be blocked by raising the first stopper 12, so that the first side panel 8 and the second side panel 9 are parked at the first side panel parking position 101 and the second side panel parking position 102, respectively. It should be noted that the first stopper 12 at the front end of the second side panel parking position 102 needs to be raised only after the first side panel 8 passes, so as to avoid blocking the first side panel 8. It should also be noted that, as Figure 3 As shown, the first stopper 12 is connected to a first lifting driving member 13 for driving the first stopper 12 to move up and down. In this embodiment, the first lifting driving member 13 is specifically a hydraulic cylinder.

[0056] like Figure 4-Figure 7 As shown, in this embodiment, the flipping device 3 specifically includes a flip seat 31, which is arranged between the conveyor roller line 1 and the side panel placement platform 2. A flip shaft 32 is installed in the flip seat 31. The flip shaft 32 is rotatably connected to the flip seat 31, and the rotation axis of the flip shaft 32 is parallel to the conveying direction of the conveyor roller line 1. The outer periphery of the flip shaft 32 is connected to a first end picker 33 for sucking the first side panel 8 from the bottom. One end of the flip shaft 32 is connected to a flip driving member 34 for driving the flip shaft 32 to rotate. It should be noted that the flip driving member 34 used in this embodiment is specifically a motor, and the output shaft of the motor is connected to the flip shaft 32 to drive the flip shaft 32 to rotate.

[0057] In order to facilitate the first end tool 33 to suck the first side plate 8 from the bottom of the first side plate 8, as shown in FIG. Figure 4 and Figure 5As shown, the first end picker 33 includes a plurality of flip rods 331 connected to the flip shaft 32, and the end of the flip rod 331 away from the flip shaft 32 is provided with a first suction cup 332 for sucking the bottom of the first side panel 8, and the end of the flip rod 331 away from the flip shaft 32 extends between the adjacent rollers 11 at the first side panel parking position 101 in the conveying roller line 1, so as to suck the first side panel 8 parked in the first side panel parking position 101 from below the first side panel parking position 101. In this embodiment, the flip rod 331 is extended between the adjacent rollers 11 at the first side panel parking position 101 in the conveying roller line 1, so as to suck the first side panel 8 parked in the first side panel parking position 101 from below the first side panel parking position 101 through the first suction cup 332 provided on the flip rod 331. It should be noted that the plurality of flip rods 331 are evenly distributed below the first side panel parking position 101 to ensure that the first side panel 8 is stably sucked. It should also be noted that, as Figure 4 As shown, the frame of the conveyor roller line 1 is opened at the position where the turning rod 331 extends to prevent the turning of the turning rod 331 from being hindered.

[0058] like Figures 8-11 As shown, in this embodiment, the translation conveying device 4 specifically includes a support frame 41, which is arranged on one side of the conveying roller line 1, and multiple groups of conveyor belts 42 are installed on the support frame 41; each group of conveyor belts 42 includes a wheel frame 421, a driving wheel 422 and a driven wheel 423 installed at both ends of the wheel frame 421, and a transmission belt 424 that is transmission-connected between the driving wheel 422 and the driven wheel 423; one end of the wheel frame 421 on which the driving wheel 422 is installed is installed on the support frame 41, and the side plate placement position 401 is arranged at one end of the conveyor belt 42 close to the driving wheel 422, and one end of the wheel frame 421 on which the driven wheel 423 is installed extends between the adjacent rollers 11 at the second side plate parking position 102 in the conveying roller line 1; the driving wheels 422 of multiple groups of conveyor belts 42 are connected in sequence through a connecting shaft 44 for synchronous rotation, and the translation conveying device 4 also includes a translation conveying drive member 45 for driving the driving wheels 422 of multiple groups of conveyor belts 42 to rotate synchronously. In the above-mentioned translation conveying device 4, multiple sets of conveyor belts 42 are provided to extend between adjacent rollers 11 at the second side plate parking position 102 of the conveyor roller line 1. The multiple sets of conveyor belts 42 are supported by the support frame 41, so as to facilitate translation of the second side plate 9 parked on the second side plate parking position 102 of the conveyor roller line 1 to the side plate placement position 401; the driving wheels 422 of the multiple sets of conveyor belts 42 are driven to rotate synchronously by the translation conveying drive member 45, so as to ensure the translation of the second side plate 9. It should be noted that, if Figure 4 As shown, the side panel placement position 401 is preferably set at a position flush with the side panel placement platform 2 and on one side of the side panel placement platform 2, so that the subsequent manipulator 5 can reciprocate between the side panel placement platform 2 and the side panel placement position 401 through linear motion. It should also be noted that, as Figure 8As shown, multiple conveyor belts 42 are evenly distributed along the length direction of the second side panel parking position 102 to ensure smooth transportation of the second side panel 9. It should be further explained that, as Figure 8 and Figure 9 As shown, the translational conveying drive member 45 used in this embodiment includes a translational conveying motor 451, and a first pulley 452 is provided at the output shaft end of the translational conveying motor 451. A second pulley 454 is provided on the connecting shaft 44 between the two adjacent groups of conveyor belts 42. The first pulley 452 and the second pulley 454 are connected by a belt 453, so that the driving wheels 422 of multiple groups of conveyor belts 42 are driven to rotate synchronously through the translational conveying motor 451 and the pulley transmission to realize synchronous transportation of multiple groups of conveyor belts 42.

[0059] In order to prevent the translation conveying device 4 from affecting the conveying of the conveying roller line 1, Figures 9-11 As shown, one end of the wheel frame 421 equipped with the driving wheel 422 is rotatably mounted on the support frame 41. The wheel frames 421 of multiple conveyor belts 42 are connected as a whole through a connecting frame 43. The connecting frame 43 is located below the wheel frame 421. The connecting frame 43 is connected to a lifting drive 48. The lifting drive 48 is installed on the support frame 41. The lifting drive 48 is used to drive the connecting frame 43 to move up and down to drive the end of the wheel frame 421 equipped with the driven wheel 423 to move up and down between a first position lower than the conveyor roller line 1 and a second position flush with the conveyor roller line 1. Figure 10 As shown, when the first side plate 8 and the second side plate 9 are being transported on the conveyor roller line 1, the connecting frame 43 is driven by the lifting driving member 48 to drive the end of the wheel frame 421 equipped with the driven wheel 423 to be lowered to the first position, which can prevent the conveyor belt 42 of the translation conveying device 4 from contacting the first side plate 8 and the second side plate 9 being transported on the conveyor roller line 1, thereby ensuring that the first side plate 8 and the second side plate 9 are normally transported on the conveyor roller line 1; as shown Figure 11 As shown, after the second side panel 9 is parked at the second side panel parking position 102, the lifting drive member 48 drives the connecting frame 43 to drive the end of the wheel frame 421 equipped with the driven wheel 423 to be lifted to the second position, so that the conveyor belt 42 of the translation conveyor device 4 can contact the second side panel 9 parked at the second side panel parking position 102, thereby realizing the translation of the second side panel 9 through the translation conveyor device 4. It should be noted that, as Figure 9 As shown, in this embodiment, the lifting drive member 48 is specifically a hydraulic cylinder.

[0060] In order to make the second side plate 9 move horizontally into place, Figures 8-11 As shown, in this embodiment, the translation conveying device 4 further includes a second stopper 46 that can be raised and lowered relative to the conveyor belt 42.
