Description

Technical Field

[0001] This utility model relates to the field of automatic cartoning machine technology, and in particular to a feeding device for an automatic cartoning machine. Background Technology

[0002] In the operation process of an automatic cartoning machine, the pushing device is the core device that connects the material conveying line and the carton conveying line. The pushing device accurately pushes the products to be packed on the material conveying line into the synchronously conveyed carton to realize the automated cartoning of products.

[0003] Currently, to avoid the problem of material falling due to the absence of a material box on the conveyor line when the pushing action is triggered, or the formation of an empty box after pushing due to the absence of a product on the conveyor line, existing technologies generally use vision sensors to collect the material box position signal and the product presence signal on the conveyor line in real time. These signals are then transmitted to the control system, which determines whether to drive the pushing cylinder to perform the pushing action, thus ensuring the accuracy of the pushing operation. However, the solution using vision sensors for identification is costly, requiring the simultaneous configuration of image acquisition cards, vision recognition modules, and other equipment, significantly increasing the operating and maintenance costs. Furthermore, the solution combining vision sensors and pushing cylinders requires multiple sets of pushing cylinders arranged side-by-side and numbered so that the control system can control the corresponding pushing cylinder action based on the vision signal. Since the extension and retraction of the pushing cylinders takes time, this further increases the operating cost and reduces the boxing efficiency of the automatic cartoning machine. Therefore, it is necessary to improve the pushing device of the existing automatic cartoning machine to reduce operating costs while improving boxing efficiency. Utility Model Content

[0007] The present invention is further configured such that: the push rod assembly includes a set of sliding mounting rods arranged in parallel on the push rod conveyor line and conveyed synchronously with the push rod conveyor line; a sliding sleeve is slidably connected to the sliding mounting rod along the conveying direction perpendicular to the push rod conveyor line; a sliding mounting seat is fixedly connected to the sliding sleeve; a push rod for pushing the material on the material conveyor line into the material box on the material box conveyor line is fixedly connected to the sliding mounting seat along the sliding direction parallel to the sliding sleeve; and a sliding guide block is fixedly connected to the bottom of the sliding mounting seat and slides within the clearance guide groove or the push guide groove.

[0008] The present invention is further configured such that: the feeding selection component includes a feeding sliding groove that is combined and disposed at the entrance of the clearance guide groove and the pushing guide groove; a separation seat is fixedly connected at the entrance of the clearance guide groove and the pushing guide groove; a rotating sealing plate for closing the clearance guide groove or the pushing guide groove is rotatably connected to the separation seat; the rotating sealing plate is rotatably connected to the separation seat based on a first rotating shaft; a first connecting rod is fixedly connected to the first rotating shaft; a rotary cylinder is hinged to the base to push the first connecting rod and thereby drive the first rotating shaft to rotate; the telescopic end of the rotary cylinder is hinged to the first connecting rod.

[0009] The present invention is further configured such that: the pusher guide groove includes a fixed guide plate fixedly connected to the base and a rotating guide plate rotatably connected to the separating seat at one end; a sliding groove for sliding of the sliding guide block is formed between the fixed guide plate and the rotating guide plate; a discharge adjustment electric cylinder for adjusting the discharge angle of the sliding mounting seat to achieve automatic reset of the pusher rod is hinged to the end of the rotating guide plate away from the separating seat; a guide mounting plate is fixedly connected to the base; a guide sliding groove is opened on the guide mounting plate; a guide sliding block is slidably connected in the guide sliding groove; and the rotating guide plate is fixedly connected to the guide sliding block.

[0010] The present invention is further configured such that: the base is fixedly provided with a reset sliding groove at the bottom of the clearance guide groove for the sliding guide block to slide; a guide disk is fixedly connected coaxially at one end of the driven transmission shaft near the clearance guide groove; and a rotation guide groove that cooperates with the sliding guide block is provided on the guide disk.

[0012] In summary, this utility model has the following beneficial effects: 1. By using laser sensors on the box conveyor line and the material conveyor line to detect in real time whether there are boxes and materials at the corresponding workstations, and by setting up clearance guide grooves and material push guide grooves on the push rod conveyor line, and setting up feeding selection components at the entrances of clearance guide grooves and material push guide grooves, when both boxes and materials are detected, the rotary cylinder extends to drive the first connecting rod and the first rotating shaft to rotate, which in turn drives the rotary sealing plate to rotate, thereby closing the clearance guide groove and opening the material push guide groove. This causes the sliding guide block of the push rod assembly to move along the material push guide groove, thereby driving the sliding mounting base, sliding sleeve and material push rod to slide along the sliding mounting rod to achieve material push. Conversely, if a box or material is missing, the rotary cylinder retracts to drive the rotary sealing plate to close the material push guide groove and open the clearance guide groove. The sliding guide block moves in a straight line along the clearance guide groove and does not perform material push. This reduces the overall use and maintenance costs. At the same time, because the material push conveyor line moves synchronously with the box conveyor line and the material conveyor line, the efficiency of boxing is greatly improved. 2. A feeding guide groove is formed by a fixed guide plate and a rotating guide plate. The rotating guide plate is driven by a discharge adjustment electric cylinder to rotate around the separation, thereby changing the outlet angle formed by the rotating guide plate and the fixed guide plate, thus adjusting the discharge angle of the sliding mounting seat. Since the push rod assembly moves at high speed with the feeding conveyor line, the movement of the sliding mounting seat can be decomposed into a component velocity perpendicular to the push rod conveyor line, thereby driving the push rod to reset. The discharge angle of the sliding mounting seat can be changed to adapt to the push rod reset requirements under different conveying speeds. Attached Figure Description

[0015] The present invention will be further described in detail below with reference to the accompanying drawings.

[0016] Example: refer to Figures 1 to 5A feeding device for an automatic cartoning machine includes a base 1. A box conveyor line 2 and a material conveyor line 3 for conveying materials are fixedly connected to the base 1. A push rod conveyor line 4 is also fixedly connected in parallel to the base 1. The box conveyor line 2, material conveyor line 3, and push rod conveyor line 4 all use chain conveyors and move synchronously. The driving sprockets and driven sprockets of the box conveyor line 2, material conveyor line 3, and push rod conveyor line 4 are coaxially fixedly connected to the same driving shaft 9 and the same driven shaft 10, respectively. A sprocket drive motor 11 for driving the driving shaft 9 is fixedly connected to the base 1. By setting the driving sprockets and driven sprockets of the box conveyor line 2, material conveyor line 3, and push rod conveyor line 4 to be coaxially fixedly connected to the same driving shaft 9 and the same driven shaft 10, and driven by the same sprocket drive motor 11, synchronous movement of the three conveyor lines is ensured, avoiding deviations in the conveying rhythm. To ensure precise alignment of the feeding action and the material box with the material, several push rod assemblies 5 are fixedly connected at even intervals along the conveying direction on the push rod conveyor line 4 for feeding materials. The base 1 is provided with a clearance guide groove 6 and a feeding guide groove 7 in the push rod conveyor line 4. At the intersection of the entrances of the clearance guide groove 6 and the feeding guide groove 7, there is an infeed selection component 8 that controls the feeding state based on the conveying path of the push rod assembly 5. The material box conveyor line 2 and the material conveyor line 3 are equipped with laser sensors for detecting materials. When both the material box and the material are detected, the push rod assembly 5 moves from the feeding guide groove 7 to feed the material into the box. Conversely, if the material box or the material is missing, the push rod assembly 5 slides from the clearance guide groove 6 and does not perform the feeding action. By replacing the traditional vision sensor with a laser sensor and the push rod assembly 5 with the transmission pushing cylinder, the cost of use and manufacturing is greatly reduced, and it can adapt to a higher conveying speed, thus improving the efficiency of boxing.

[0017] refer to Figure 3 and Figure 5Specifically, the pusher assembly 5 includes a set of sliding mounting rods 51 arranged in parallel on the pusher conveyor line 4 and conveyed synchronously with the pusher conveyor line 4. A sliding sleeve 52 is slidably connected to the sliding mounting rod 51 along a conveying direction perpendicular to the pusher conveyor line 4. A sliding mounting base 53 is fixedly connected to the sliding sleeve 52. A pusher rod 54 for pushing material on the material conveyor line 3 into the material box on the material box conveyor line 2 is fixedly connected to the sliding mounting base 53 along a sliding direction parallel to the sliding sleeve 52. A sliding rod 54 is fixedly connected to the bottom of the sliding mounting base 53. The sliding guide block (not shown in the attached figure) moves within the clearance guide groove 6 or the material pushing guide groove 7. To ensure the smooth sliding of the sliding guide block, the sliding guide block has a cylindrical structure. When both the material and the material box are detected, the sliding guide block of the push rod assembly 5 moves along the material pushing guide groove 7, thereby driving the sliding mounting base 53, the sliding sleeve 52 and the material pushing rod 54 to slide along the sliding mounting rod 51 to achieve material pushing. Conversely, if the material box or the material is missing, the sliding guide block moves in a straight line along the clearance guide groove 6 and does not perform the material pushing action.

[0018] refer to Figure 3 and Figure 4 Specifically, the feeding selection component 8 includes a feeding sliding groove 81 that converges and converges at the inlet of the clearance guide groove 6 and the pushing guide groove 7. A separation seat 82 is also fixedly connected at the inlet of the clearance guide groove 6 and the pushing guide groove 7. A rotating sealing plate 83 for closing the clearance guide groove 6 or the pushing guide groove 7 is rotatably connected to the separation seat 82. The rotating sealing plate 83 is rotatably connected to the separation seat 82 based on a first rotating shaft 84. A first connecting rod 85 is fixedly connected to the first rotating shaft 84. A rotary cylinder 86 is hinged to the base 1 to push the first connecting rod 85 and thereby drive the first rotating shaft 84 to rotate. The telescopic end of the rotary cylinder 86 is hinged to the first connecting rod 85. By extending and retracting the rotary cylinder 86, the first connecting rod 85 and the first rotating shaft 84 are driven to rotate, which in turn drives the rotary sealing plate 83 to rotate, thereby closing the clearance guide groove 6 or the pushing guide groove 7 and controlling the movement direction of the sliding guide block.

[0019] refer to Figure 1 and Figure 2Specifically, the pusher guide groove 7 includes a fixed guide plate 71 fixedly connected to the base 1 and a rotating guide plate 72 rotatably connected to the separating seat 82 at one end. A sliding groove for sliding guide blocks is formed between the fixed guide plate 71 and the rotating guide plate 72. The end of the rotating guide plate 72 away from the separating seat 82 is hinged to a discharge adjustment electric cylinder 73 for adjusting the discharge angle of the sliding mounting seat 53 to achieve automatic reset of the pusher rod 54. A guide mounting plate 74 is fixedly connected to the base 1. A guide sliding groove 75 is formed on the guide mounting plate 74. The guide sliding groove 75 is for sliding blocks to slide in. The sliding mounting base 53 is dynamically connected to a guide sliding block 76, and a rotating guide plate 72 is fixedly connected to the guide sliding block 76. The rotating guide plate 72 is driven to rotate around the separation by the discharge adjustment electric cylinder 73, thereby changing the outlet angle formed by the rotating guide plate 72 and the fixed guide plate 71, thus adjusting the discharge angle of the sliding mounting base 53. Since the push rod assembly 5 moves at high speed with the push conveyor line, the movement of the sliding mounting base 53 can be decomposed into a component velocity perpendicular to the push rod conveyor line 4, thereby driving the push rod to reset. The discharge angle of the sliding mounting base 53 can be changed to adapt to the push rod reset under different conveying speeds. The base 1 is fixedly provided with a reset sliding groove 12 at the bottom of the clearance guide groove 6 for the sliding guide block to slide. The driven drive shaft 10 is coaxially fixedly connected to a guide disk 13 at one end near the clearance guide groove 6. A rotary guide groove 14 that cooperates with the sliding guide block is opened on the guide disk 13. By setting the reset sliding groove 12 and the guide disk 13 and setting the rotary guide groove 14 on the guide disk 13, the sliding guide block is guided to move smoothly, avoiding the problem of jamming during high-speed movement, and improving the stability of the boxing process. The inlet of the feeding sliding groove 81 is widened and faces the rotary guide groove 14 so that the sliding guide block can enter the feeding sliding groove 81.

[0020] Brief description of the usage process: When the laser sensor detects that both the material box and the material are present, the rotary cylinder 86 extends, driving the first connecting rod 85 and the first rotating shaft 84 to rotate, which in turn drives the rotary sealing plate 83 to rotate, thereby closing the clearance guide groove 6 and opening the material pushing guide groove 7. This causes the sliding guide block of the push rod assembly 5 to move along the material pushing guide groove 7, thereby driving the sliding mounting base 53, the sliding sleeve 52 and the push rod 54 to slide along the sliding mounting rod 51 to achieve material pushing. Conversely, if the material box or the material is missing, the rotary cylinder 86 retracts, driving the rotary sealing plate 83 to close the material pushing guide groove 7 and open the clearance guide groove 6. The sliding guide block moves linearly along the clearance guide groove 6 and does not perform the material pushing action.
