Description

Technical Field

[0001] This utility model relates to the field of carton packing machines, and more specifically, it relates to a carton feeding sensing device for carton packing machines. Background Technology

[0002] A carton packer is a device that semi-automatically or automatically packs unpackaged or small-packaged products into transport packaging. Its working principle is to pack the products into cartons in a certain arrangement and quantity, and then close or seal the opening of the carton. Existing automatic carton packing machines typically use a liftable picking rack to transport stacked cartons from the carton hopper to the next packing step. Multiple suction nozzles at the bottom of the picking rack are used to pick up and transport the cartons. This method usually involves controlling the height of the picking rack's descent via a system setting to allow the nozzles to grip the cartons. However, this method is problematic when the stacking height of the cartons changes. Gaps appear between the cartons due to stacking, and over time, these gaps can be squeezed away, causing the stack height to decrease. This results in a larger distance between the nozzles and the cartons when the machine reaches the preset position, reducing the suction force and making the cartons prone to falling midway through the process. The machine suffers from poor stability in picking up cartons, and the system settings need to be adjusted based on the individual thickness of the cartons, making operation time-consuming and labor-intensive. Improvements are urgently needed. Utility Model Content

This feeding sensing device can accurately control the distance of the suction nozzle to the carton material each time, so that the suction nozzle can stably adsorb the carton material for feeding.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a carton feeding sensing device for a carton packing machine, comprising a feeding bracket and a suction nozzle fixed below the feeding bracket. The feeding bracket is equipped with a feeding sensing device, which includes a fixed bracket, an adjusting bracket, a sensor, a fixed base, and a sliding rod. The fixed bracket is fixed above the feeding bracket, the adjusting bracket is slidably mounted on the fixed bracket, the sensor is fixed at the end of the adjusting bracket, the fixed base is fixed on the feeding bracket and located on one side of the sensor, and the sliding rod is slidably mounted on the fixed base. The upper end of the sliding rod is provided with a sensing coil that cooperates with the sensor, the lower end extends below the suction nozzle, and a top plate for contacting the carton is provided at the lower end of the sliding rod.

[0005] The present invention is further configured such that: the fixed bracket is L-shaped, and one end of the fixed bracket is horizontally fixedly connected to the material picking bracket by bolts, and the other end is vertically set with a sliding block that slides vertically; one end of the adjusting bracket is fixedly connected to the sliding block by bolts.

[0006] The present invention is further configured such that: the fixed base includes a fixed tube passing through the material picking bracket, and an mounting seat is provided on the circumference of the end of the fixed tube; the mounting seat is fixedly connected to the material picking bracket by bolts; and the sliding rod is adapted to be installed in the fixed tube and slides up and down in cooperation.

[0007] The present invention is further configured such that a rubber pad is fitted over the sliding rod, and the rubber pad is located above the fixed base.

[0012] Reference Figure 1 and Figure 2 The embodiments of this utility model will be further described below.

[0013] This utility model discloses a carton feeding sensing device for a carton packing machine, including a feeding bracket 1 and a suction nozzle 10 fixed below the feeding bracket 1. The feeding bracket 1 is provided with a feeding sensing device 2, which includes a fixed bracket 20, an adjusting bracket 21, a sensor 22, a fixed base 23, and a sliding rod 24. The fixed bracket 20 is fixed above the feeding bracket 1. The adjusting bracket 21 is slidably mounted on the fixed bracket 20. The sensor 22 is fixed at the end of the adjusting bracket 21. The fixed base 23 is fixed on the feeding bracket 1 and located on one side of the sensor 22. The sliding rod 24 is slidably mounted on the fixed base 23. The upper end of the sliding rod 24 is provided with a sensing coil 240 that senses and cooperates with the sensor 22, and the lower end extends below the suction nozzle 10. A top plate 241 for contacting the carton is provided at the lower end of the sliding rod 24. The fixed bracket 20 is L-shaped, with one horizontal end fixedly connected to the material-picking bracket 1 by bolts, and the other vertical end equipped with a sliding block 200 that slides vertically. One end of the adjusting bracket 21 is fixedly connected to the sliding block 200 by bolts. The fixed base 23 includes a fixed tube 230 passing through the material-picking bracket 1, with a mounting seat 231 circumferentially arranged at the end of the fixed tube 230. The mounting seat 231 is fixedly connected to the material-picking bracket 1 by bolts. The sliding rod 24 is fitted inside the fixed tube 230 and slides vertically. A rubber pad 25 is also sleeved on the outside of the sliding rod 24, located above the fixed base 23. By sleeved with the rubber pad 25 on the sliding rod 24, the induction coil 240 at the upper end of the sliding rod 24 can be buffered and damped by the rubber pad 25 when the material-picking bracket 1 is not picking up cardboard material, resulting in a more stable structure.

[0014] Working principle: When the material handling bracket 1 is not descending to handle the material, if... Figure 1 As shown, the sliding rod 24 slides downwards under gravity until the induction coil 240 abuts against the fixed base 23. At this time, the top plate 241 at the lower end of the sliding rod 24 slides below the suction nozzle 10. When the material picking bracket 1 descends to pick up the material, the top plate 241 first touches the cardboard material. As the material picking bracket 1 continues to descend, the sliding rod 24 will slide upwards under the force of the material picking bracket 1. When the induction coil 240 at the upper end of the sliding rod 24 slides to the side of the sensor 22, the sliding rod 24 will slide behind the suction nozzle 10. At this time, the suction nozzle 10 will form a squeezing force with the cardboard material, and the sensor 22 will receive the sensing signal from the induction coil 240 to stop the descent of the material picking bracket 1 and start the suction nozzle 10 to pick up the cardboard material, and then proceed to the next step of cardboard material conveying. When the cardboard material is conveyed to the designated position, the suction nozzle 10 is closed to complete the unloading. At this time, the sliding rod 24 will return to its original position under gravity for the next sensing and picking.

[0015] This practical feeding sensing device 2 utilizes the up-and-down sliding sensing of the sliding rod 24 to achieve precise positioning of the suction nozzle 10. This ensures that the distance the material-picking bracket 1 reaches the cardboard material is the effective suction distance of the suction nozzle 10, eliminating concerns about changes in the stacking height of the cardboard materials and ensuring the suction nozzle 10 consistently and stably holds the material for feeding. When changing to cardboard materials of different thicknesses, simply adjusting the height of the adjusting rod (i.e., the sensing height of the sensor) adjusts the suction force between the suction nozzle 10 and the cardboard, allowing for rapid adjustment of the suction force for different cardboard thicknesses without requiring system resetting, saving time and effort.

[0016] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
