[0025] To illustrate the technical content, structural features, objectives, and effects of this invention in detail, the following description, in conjunction with the accompanying drawings and embodiments, will provide a detailed explanation of the invention.

[0026] Please see Figure 1 This is a schematic diagram of the system structure of an automatic bar packaging device according to an embodiment of the present invention.

[0028] The control device 90 includes a processing unit 91, a storage unit 92 that establishes a communication connection with the processing unit 91, a display unit 93, and an input unit 94.

[0029] The storage unit 92 is used to store the program run by the processing unit 91, the processed data, and the received data.

[0030] The display unit 93 is used to display an automatic bar packing control interface in response to the control of the processing unit 91.

[0031] The input unit 94 is used to input control commands or parameters into the automatic bar packing control interface; specifically, the input unit 94 is at least one of a touch screen, keyboard, mouse or control buttons.

[0032] The feeding device 30 includes a material tray 31.

[0033] The boxing device 50 includes a material distribution plate 51.

[0034] The positioning device 70 includes a material box 71.

[0035] The processing unit 91 includes: a material distribution control module 910, a material handling control module 911, a material pushing control module 912, a transplanting control module 913, a boxing control module 914, a top box control module 915, a positioning control module 916, and a repositioning control module 917.

[0036] The material distribution control module 910 establishes a communication connection with the material distribution device 10, and is used to control the material distribution device 10 to pick up the bar to be tested and make the bar to be tested fall onto the material tray 31 of the pusher device 30.

[0037] The material handling control module 911 establishes a communication connection with the material handling device 20, and controls the material handling device 20 to move m times according to a preset first stroke and move once according to a preset second stroke, so as to sort the m bars that have fallen on the material tray 31 one by one. The first stroke is the material handling device 20 reciprocating with a first moving distance value, and the second stroke is the material handling device 20 reciprocating with a second moving distance value; m is a natural number, and the value of m is preset according to the capacity of the material box 71 and the size of the bars. In this embodiment, the first moving distance value is equal to h, and the second moving distance value is equal to 4h; where h is the diameter of the bar. The material handling control module 911 continuously controls the material handling device 20 to move alternately with the first stroke and the second stroke, thereby continuously sorting the bars that have fallen on the material tray 31 in groups of m bars.

[0038] The feeding control module 912 establishes a communication connection with the feeding device 30 and is used to control the movement of the feeding device 30 to push the m rods onto the material distribution plate 51 of the boxing device 50.

[0039] The transplanting control module 913 establishes a communication connection with the transplanting device 40 and controls the transplanting device 40 to transplant the m rods placed on the material distribution plate 51 into the material box 71 of the positioning device 70.

[0040] The boxing control module 914 establishes a communication connection with the boxing device 50 and controls the boxing device 50 to pull away the material distribution plate 51 so that the m rods fall into the material box 71 together.

[0041] As described above, the automatic bar packaging equipment 1 controls the material handling device 20 to sequentially arrange multiple bars according to a predetermined first stroke and second stroke. The pusher device 30 and the transfer device 40 work together to load the arranged bars into the material box 71 at once, thereby realizing the automatic batch arrangement and packaging of bars.

[0042] Furthermore, the top box control module 915 establishes a communication connection with the top box device 60 to control the top box device 60 to perform a top box operation on the material box 71, so that the bottom layer of bars falling into the material box 71 are neatly distributed.

[0043] Specifically, the top box control module 915 is used to control the top box device 60 to perform a top box operation on the material box 71 when the boxing device 50 puts the 1st to xth rods into the material box 71; and to control the top box device 60 to stop working when the boxing device 50 puts the (x+1)th to fth rods into the material box 71. Here, f is the maximum number of rods that the material box 71 can hold, and the f rods are stored in the material box 71 in the form of x rods per layer, accumulating to f / x layers, where x and f are natural numbers, and m... x.

[0044] For example, f=1000, x=50, that is, the maximum number of bars that the material box 71 can hold is 1000, and the 1000 bars are stored in the material box 71 in the form of 50 bars per layer and stacked in 20 layers. The 50 rods in each layer need to be loaded into the material box 71 in four stages by the boxing device 50. Specifically, the boxing device 50 loads 13 rods into the material box 71 for the first time, and the top boxing device 60 operates to top the material box 71 once; the boxing device 50 loads 12 rods into the material box 71 for the second time, and the top boxing device 60 operates to top the material box 71 once; the rotary cylinder 54 operates, driving the slide cylinder 53, the limiting plate 52, the material distribution plate 51, and the m rods on the material distribution plate 51 to rotate 180 degrees together; the boxing device 50 loads 13 rods into the material box 71 for the third time, and the top boxing device 60 operates to top the material box 71 once; the boxing device 50 loads 12 rods into the material box 71 for the fourth time, and the top boxing device 60 operates to top the material box 71 once. This operation ensures that the 50 bars are laid flat in one layer at the bottom of the material box 71. After the boxing device 50 has loaded 13 bars into the material box 71 for the fifth time (i.e., loaded the second layer of bars), the top box device 60 no longer operates to top the material box 71.

[0045] As described above, under the action of the top box device 60, the rods pushed by the transplanting device 40 into the material box 71 are sorted to avoid confusion when transplanting rods in batches, thereby realizing automatic sorting and boxing of rods in batches.

[0046] The positioning control module 916 establishes a communication connection with the positioning device 70, and is used to control the positioning device 70 to accurately position the material box 71 on the boxing station 82 before the boxing device 50 loads the rod into the material box 71; and after the boxing device 50 loads the rod into the material box 71, control the positioning device 70 to remove the limit on the material box 71, so that the top boxing device 60 performs a top boxing operation on the material box 71.

[0047] The switching device 80 is pre-set with an empty box waiting station 81, a boxing station 82, and a full box unloading station 83.

[0048] The processing unit 91 further includes a switching control module 917, which establishes a communication connection with the switching device 80 and controls the switching device 80 to switch the material box 71 between the empty box waiting station 81, the boxing station 82, and the full box unloading station 83. Specifically, the operator pre-places an empty material box 71 in the empty box waiting station 81. When the automatic bar boxing control process of this invention begins, the switching control module 917 moves the material box 71 located in the empty box waiting station 81 to the boxing station 82, so that the positioning device 70 positions the material box 71 in the boxing station; and when the material box 71 is full, it moves the material box 71 located in the boxing station 82 to the full box unloading station 83, so that the operator removes the full material box 71 from the full box unloading station 83.

The transplanting device 40 is mounted on the table surface of the equipment platform 101 by a connecting bracket and is located close to the material dispensing device 10, positioned on the other side of the material dispensing device 10, opposite to the material pushing device 30. The boxing device 50 is positioned between the material dispensing device 10 and the transplanting device 40. The top box device 60 is fixed below the table surface of the equipment platform 101 via a transition plate. The positioning device 70 is installed above the table surface of the equipment platform 101 via a linear rail. The shifting device 80 is installed below the table surface of the equipment platform 101. The movable end of the shifting cylinder of the shifting device 80 is connected to the boxing plate of the positioning device 70 via a transition plate. The top box device 60 is set up corresponding to the boxing station of the shifting device 80.

[0052] Please see Figure 3 ,for Figure 2 A partially enlarged schematic diagram of part A of the automatic bar packaging equipment shown.

[0053] The material distribution device 10 includes: a material distribution mechanism 11 and a first servo motor 12; wherein, the first servo motor 12 is shaft-connected to the material distribution mechanism 11 via a coupling 120, and the first servo motor 12 can rotate in response to the control of the material distribution control module 910, thereby driving the material distribution mechanism 11 to rotate synchronously.

[0054] The material handling device 20 includes: a first slide cylinder 21 and a dual-axis cylinder 22; wherein, the first slide cylinder 21 is fixed below the table surface of the equipment platform 101 by a mounting bracket, and the dual-axis cylinder 22 is mounted above the first slide cylinder 21 by a transition plate.

[0055] The pushing device 30 includes: a material tray 31, a second slide cylinder 32, and a push plate 33; wherein, the material tray 31 is disposed near the material distribution mechanism 11; the push plate 33 is fixedly connected to the second slide cylinder 32, and the push plate 33 can reciprocate along the surface of the material tray 31 under the push of the second slide cylinder 32, thereby pushing the bar material rolling on the material tray 31.

[0056] The material distribution control module 910 controls the first servo motor 12 to rotate, thereby driving the material distribution mechanism 11 to rotate, so as to pick up the material from the material box (not shown) containing the bar, and drive the picked-up bar to continue rotating and fall onto the material tray 31 of the pusher device 30, thereby completing the feeding.

[0057] The material handling control module 911 controls the dual-axis cylinder 22 to move m times according to the first stroke, thereby pushing the bars located on the material tray 31 to sort out the m bars that have fallen on the material tray 31 one by one.

[0058] The material handling control module 911 further controls the first slide cylinder 21 to move according to the second stroke after the dual-axis cylinder 22 has moved m times according to the first stroke, thereby moving the m bars to the pushing station. The pushing station is a station on the material handling device 20 corresponding to the pushing device 30.

[0059] The feeding control module 912 controls the second slide cylinder 32 to move, thereby driving the pusher plate 33 to move on the surface of the material tray 31, and simultaneously pushing the m bars corresponding to the feeding station onto the material distribution plate 51 of the boxing device 50, thus completing the feeding of the m bars.

[0060] As described above, the reciprocating stroke of the dual-axis cylinder 22 of the material handling device 20 is fixed, moving a distance equal to the diameter of one bar each time (i.e., the first moving distance value, h). The dual-axis cylinder 22 pushes one bar forward by a distance equal to the diameter, moving it to the next groove. Subsequently, under the action of the dual-axis cylinder 22, the bars move forward, thus arranging them into a row. When a row of 12 or 13 bars is reached, the first slide cylinder 21 pushes the entire row of bars forward by a distance equal to four times the diameter (i.e., the second moving distance value, 4h) to the pushing station. Then, the second slide cylinder 32 of the pushing device 30 drives the pusher plate 33 to push the entire row of bars onto the distribution plate 51 of the boxing device 50.

[0068] Drive the Z-axis electric cylinder 41 and the X-axis electric cylinder 42 to move the m rods that were placed on the material distribution plate 51 in two separate operations to the first area and the second area inside the material box 71, respectively.

[0069] Control the rotary cylinder 54 to rotate 180 degrees; and

[0070] The Z-axis electric cylinder 41 and X-axis electric cylinder 42 are driven to move the m rods placed on the material distribution plate 51 in two separate operations to the third and fourth regions inside the material box 71, respectively. The internal space of the material box 71 is divided into a first region and a second region on one side, and a third region and a fourth region on the other side, along the central axis.

[0071] Specifically, when f=1000 and x=50, that is, the maximum number of rods that the material box 71 can hold is 1000, and the 1000 rods are stored in the material box 71 in a stack of 20 layers of 50 rods each. The number of rods (50 rods) in each layer is preset to 13, 12, 13, 12 by the software program, so that the pushing device 30, the transferring device 40, and the boxing device 50 work together to put the rods into the material box 71 in four batches. Specifically, the transplanting control module 913 drives the Z-axis electric cylinder 41 and the X-axis electric cylinder 42 to simultaneously transplant 13 rods placed on the material distribution plate 51 into the first area inside the material box 71; and drives the Z-axis electric cylinder 41 and the X-axis electric cylinder 42 to simultaneously transplant 12 rods placed again on the material distribution plate 51 into the second area inside the material box 71, realizing the picking and placing of rods (a total of 25 rods) twice. Then, the transplanting control module 913 controls the rotary cylinder 54 to rotate 180 degrees, and then drives the Z-axis electric cylinder 41 and X-axis electric cylinder 42 to move, simultaneously transplanting 13 rods placed on the distribution plate 51 to the third area inside the material box 71. It also drives the Z-axis electric cylinder 41 and X-axis electric cylinder 42 to move, simultaneously transplanting 12 rods placed on the distribution plate 51 to the fourth area inside the material box 71, thus realizing the picking and placing of rods (a total of 25 rods) twice. This operation completes the boxing of each layer of rods (50 rods).

[0072] Please also refer to Figure 5 ,for Figure 2 A partially enlarged schematic diagram of section C of the automatic bar packaging equipment.

[0073] The top box device 60 includes a top box mechanism 61; wherein, the double cylinder of the top box mechanism 61 is installed below the table surface of the equipment platform 101 via a connecting plate.

[0074] The positioning device 70 is installed on the table surface of the equipment base 101. Specifically, the positioning device 70 includes: a material box 71, a Y-axis positioning slide cylinder 72, an X-axis positioning slide cylinder 73, a linear guide 74, and a boxing plate 75. The linear guide 74 is fixed on the equipment base 101. The boxing plate 75 is fixed on the left and right linear guides 74. The X-axis positioning slide cylinder 72 is installed on both sides of the boxing plate 75 through connecting plates to position the left and right material boxes 71 in the X-axis direction. The Y-axis positioning slide cylinder 72 is installed on both ends of the boxing plate 75 through connecting plates and is perpendicular to the X-axis positioning slide cylinder 73. The material box 71 is placed on the boxing plate 75.

[0075] The transposition device 80 is installed under the table surface of the equipment platform 101; specifically, the transposition device 80 includes: a transposition cylinder 84; wherein, the transposition cylinder 84 is installed under the table surface of the equipment platform 101, the fixed end of the transposition cylinder 84 is fixed under the table surface of the equipment platform, and the movable end of the transposition cylinder 84 is connected to the boxing plate 75 through a transition plate.

[0076] The top box control module 915 controls the top box mechanisms 61 at both ends to move up and down alternately, causing the rods to roll back and forth in the material box 71 and eventually lay flat in a row. In this embodiment, when the boxing device 50 first puts the 1st to 13th rods into the material box 71, the top box control module 915 controls the top box mechanism 61 to move up and down alternately to perform the first top boxing operation on the material box 71; when the boxing device 50 puts the 14th to 25th rods into the material box 71 for the second time, the top box control module 915 controls the top box mechanism 61 to move up and down alternately to perform the second top boxing operation on the material box 71; the top box control module 915 in the... When the boxing device 50 puts the 26th to 38th rods into the material box 71 for the third time, it controls the top box mechanism 61 to move up and down alternately to perform the third top boxing operation on the material box 71; when the boxing device 50 puts the 39th to 50th rods into the material box 71 for the fourth time, the top box control module 915 controls the top box mechanism 61 to move up and down alternately to perform the fourth top boxing operation on the material box 71; in this way, it is ensured that the 50 rods put in can be laid flat in one layer at the bottom of the material box 71. When the boxing device 50 inserts the 51st to 63rd bars into the material box 71 for the fifth time, the top boxing device 60 stops operating and ceases to top the material box 71. Similarly, when the boxing device 50 inserts the 13th bar into the material box 71 for the fifth time (i.e., when the second layer of bars is inserted), the top boxing device 60 ceases to top the material box 71. In this operation, the top boxing control module 915 controls the top boxing mechanisms 61 at both ends to avoid stacking of the bottom layer of bars while facilitating the insertion of the 2nd to 20th layers of bars.

[0077] The positioning control module 916 is specifically used for:

[0078] Before the boxing device 50 loads the bar into the box 71, the action of the Y-axis positioning slide cylinder 72 and the X-axis positioning slide cylinder 73 is controlled to push the box 71 to achieve precise positioning of the box 71.

[0079] After the boxing device 50 loads the bar into the material box 71, it controls the piston rods of the Y-axis positioning slide cylinder 72 and the X-axis positioning slide cylinder 73 to retract, removing the limit on the material box 71, so that the top box device 60 can perform a top box operation on the material box 71.

[0080] Two empty material boxes are pre-positioned manually at the empty box waiting station and the boxing station, respectively. When a material box is filled with bar stock, the switching control module 917 specifically controls the switching cylinder 84 to push the boxing plate 75 along the rail 74, moving the full material box 71 from the boxing station to the full box unloading station, while simultaneously moving the empty box from the empty box waiting station to the boxing station, thus switching the material box 71 between full and empty. The full box is then manually removed and replaced with the previous empty box. When the box at the boxing station is refilled, the switching control module 918 controls the switching cylinder 84 to pull the boxing plate 75 in the opposite direction along the rail 74, completing the box switching again.

[0081] This invention also provides an automatic bar packaging control method, which operates in the automatic bar packaging equipment 1 described above. Please refer to [link / reference]. Figure 6 This is a flowchart illustrating an automatic bar packaging control method according to the first embodiment of the present invention.

[0082] The automatic boxing control method for bar stock includes the following steps:

[0083] In step S200, the control device 90 controls the material distribution device 10 to pick up the bar to be tested and to transfer the bar to be tested to the material tray of the pusher device 30.

[0084] In step S210, the control device 90 controls the material handling device 20 to move m times according to a preset first stroke and move once according to a preset second stroke, so as to sort out the m bars that have fallen onto the material tray 31 one by one.

[0085] Wherein, the first stroke is the reciprocating motion of the material handling device 20 with a first moving distance value, the second stroke is the reciprocating motion of the material handling device 20 with a second moving distance value, m is a natural number, and the value of m is set in advance according to the capacity of the material box 71 and the size of the bar.

[0086] In this embodiment, the first moving distance value is equal to h, and the second moving distance value is equal to 4h; where h is the diameter of the bar. The material handling control module 911 continuously controls the material handling device 20 to move alternately in the first stroke and the second stroke, thereby continuously sorting the bars that fall onto the material tray 31 in groups of m bars.

[0087] In step S220, the control device 90 controls the pusher device 30 to move so as to push the m rods onto the distribution plate 51 of the boxing device 50.

[0088] In step S230, the control device 90 controls the transplanting device 40 to transplant the m rods placed on the material distribution plate 51 into the material box 71 of the positioning device 70.

[0089] In step S240, the control device 90 controls the boxing device 50 to detach from the material distribution plate 51, so that the m rods fall together into the material box 71 of the positioning device 70. Then, the process ends.

[0090] As described above, the automatic bar packaging equipment 1 controls the material handling device 20 to sequentially arrange multiple bars according to a predetermined first stroke and second stroke. The pusher device 30 and the transfer device 40 work together to load the arranged bars into the material box 71 at once, thereby realizing the automatic batch arrangement and packaging of bars.

[0091] Please see Figure 7 This is a flowchart illustrating an automatic bar packaging control method according to the second embodiment of the present invention.

[0092] The automatic boxing control method for bar stock includes the following steps:

[0093] In step S300, the switching device 80 moves the material box 71 located on the empty box waiting station 81 to the boxing station 82, and the control device 90 controls the positioning device 70 to accurately position the material box 71 on the boxing station 82.

[0094] The switching device 80 is pre-set with an empty box waiting station 81, a boxing station 82, and a full box unloading station 83. An operator pre-places an empty box 71 in the empty box waiting station 81. When the automatic bar boxing control process of this invention begins, the switching device 80 moves the box 71 located in the empty box waiting station 81 to the boxing station 82, and the positioning device 70 positions the box 71 in the boxing station to hold the bar.

[0095] In step S310, the control device 90 controls the material distribution device 10 to pick up the bar to be tested and to transfer the bar to be tested to the material tray of the pusher device 30.

[0096] In step S320, the control device 90 controls the material handling device 20 to move m times according to a preset first stroke and move once according to a preset second stroke, so as to sort out the m bars that have fallen onto the material tray 31 one by one.

[0097] Wherein, the first stroke is the reciprocating motion of the material handling device 20 with a first moving distance value, the second stroke is the reciprocating motion of the material handling device 20 with a second moving distance value, m is a natural number, and the value of m is set in advance according to the capacity of the material box 71 and the size of the bar.

[0098] In this embodiment, the first moving distance value is equal to h, and the second moving distance value is equal to 4h; where h is the diameter of the bar. The material handling control module 911 continuously controls the material handling device 20 to move alternately in the first stroke and the second stroke, thereby continuously sorting the bars that fall onto the material tray 31 in groups of m bars.

[0099] In step S330, the control device 90 controls the pusher device 30 to move so as to push the m rods onto the distribution plate 51 of the boxing device 50.

[0100] In step S340, the control device 90 controls the transplanting device 40 to transplant the m rods placed on the material distribution plate 51 into the material box 71 of the positioning device 70.

[0101] In step S350, the control device 90 controls the boxing device 50 to pull away the material distribution plate 51 so that the m rods fall into the material box 71 of the positioning device 70 together.

[0102] In step S360, the control device 90 determines whether the number of bars placed by the boxing device 50 into the material box 71 of the positioning device 70 reaches x bars; if not, proceed to step S370; if yes, proceed to step S380.

[0103] Where f is the maximum number of rods that the material box 71 can hold, and the f rods are held in the material box 71 in the form of x rods per layer, accumulating to f / x layers, where x and f are both natural numbers, and m x.

[0104] In step S370, the control device 90 controls the positioning device 70 to remove the limit on the material box 71, and controls the top box device 60 to perform a top box operation on the material box 71, so that the bottom layer of bars falling into the material box 71 are neatly distributed; then, return to step S300.

[0105] In step S380, the control device 90 controls the set-top box device 60 to stop working.

[0106] In step S390, the control device 90 determines whether the number of bars placed by the boxing device 50 into the material box 71 of the positioning device 70 reaches f bars; if not, it returns to step S300; if yes, the process ends.

[0107] As described above, by controlling the material handling device 20 to sequentially arrange multiple rods according to a predetermined first stroke and second stroke, and by the joint action of the pushing device 30 and the transfer device 40, the arranged rods are loaded into the material box 71 at once. Under the action of the top box device 60, the rods pushed into the material box 71 by the transfer device 40 are arranged to avoid confusion when transferring rods in batches, thereby realizing the automatic arrangement and boxing of rods in batches.

[0108] Furthermore, when the control device 90 determines that the number of bars placed by the boxing device 50 into the material box 71 of the positioning device 70 reaches f bars, the method further includes:

[0109] In step S400, the switching device 80 moves the full-loaded box 71 located at the boxing station 82 to the full-load unloading station 83, and the operator removes the full-loaded box 71 from the full-load unloading station 83. Then, the process ends.

[0110] Furthermore, after the operator removes the full-box material box 71 from the full-box unloading station 83, an empty-box material box 71 is placed on the empty-box waiting station 81; the switching device 80 moves the empty-box material box 71 located on the empty-box waiting station 81 to the boxing station 82, and continues to execute the steps S300 to S400 as described above to sort and box the bar stock, which will not be elaborated here.
