Description

Technical Field

[0001] The utility model relates to the technical field of bag sorting machines, in particular to a multi-channel bag sorting machine. Background Art

[0002] For materials that are individually packaged in packaging bags, it is usually necessary to test the integrity of the packaging bags before putting them into packaging boxes or larger packaging bags. In order to ensure the accuracy of the test, the bagged materials need to be separated one by one to avoid material accumulation affecting the test.

[0003] To this end, in the prior art, for example, Chinese utility model patent No. ZL202222753809.4 discloses an automatic bag sorting machine, including a material sorting section and a conveying section. A number of photoelectric eyes are evenly arranged above the material sorting section to monitor the material on the surface of the roller below it. The multi-column spacing adjustment rollers, multi-column rejection rollers, direction rejection rollers and single-column spacing adjustment rollers on the material sorting section are arranged in a row. Each group of rollers is driven by an independent motor, and each motor runs at a differential speed based on the material information monitored by the electrically connected photoelectric eyes to increase or shorten the distance between adjacent materials.

[0004] The above bag sorting machine increases the distance between adjacent materials and completes the separation of materials by monitoring with photoelectric eyes and controlling the differential speed of each set of rollers. However, the bag sorting machine can only sort single-row materials, and the efficiency is low. If the number of bag sorting machines is increased, it is bound to increase the floor space in order to avoid mutual interference. Utility Model Content

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] like Figure 1 , 3 As shown in Figures 5 and 6, this embodiment provides a multi-channel bag sorting machine, including a frame 1, and a plurality of bag sorting mechanisms arranged on the frame 1, wherein the plurality of bag sorting mechanisms are divided into at least two layers, the bag sorting mechanisms in the upper layer are closer to the middle of the frame than the bag sorting mechanisms in the lower layer; the discharge end 22 of each bag sorting mechanism is closer to the middle of the frame than the feed end 21. This embodiment takes 4 bag sorting mechanisms as an example, which are divided into two layers, the upper layer, the upper layer, the lower ... In this way, on the one hand, the layered design avoids increasing the floor space too much; on the second hand, the staggered setting between the upper and lower bag sorting mechanisms ensures that both the feeding end and the discharging end of the lower bag sorting mechanism have enough space to avoid being affected by the upper bag sorting mechanism; on the third hand, the feeding end of each bag sorting mechanism is closer to the side of the frame, which makes it possible for the feeding ends of the two bag sorting mechanisms on each layer to have enough distance to cooperate with multiple feeding devices respectively, and at the same time, the discharging ends of the four bag sorting mechanisms are relatively compact, which is convenient for cooperating with detection equipment.

[0029] like Figure 4 As shown, the bag sorting mechanism includes a plurality of groups of bag sorting roller assemblies 31 connected in sequence, a material sensor 32 arranged at the tail end of each group of bag sorting roller assemblies 31, and a speed controller is arranged between the bag sorting roller assemblies 31 and the material sensor 32. Among them, the structure of the bag sorting roller assembly 31 is relatively conventional, and the transmission connection of 6 rollers is realized by pulleys and belts, and it is driven by a servo motor. The material sensor 32 can generally adopt a photoelectric sensor. The working principle of the bag sorting mechanism is: when material A passes through the material sensor at the tail end of the first group of bag sorting roller assemblies, that is, material A enters the second group of bag sorting roller assemblies, at this time, the first group of bag sorting roller assemblies are decelerated, while the speed of the second group of bag sorting roller assemblies where material A is located remains unchanged, thereby widening the distance between material A and the subsequent materials. By analogy, after the bag sorting action of more than ten groups of bag sorting roller assemblies, all materials can be effectively separated.

[0030] like Figure 2 As shown, the feeding end of the bag sorting mechanism is provided with a feeding roller assembly 4, and baffles 41 are provided at the head end and above both sides of the feeding roller assembly 4. Among them, the structure of the feeding roller assembly 4 is the same as that of the bag sorting roller assembly, but it is mainly used to cooperate with the feeding equipment and convey the material to the bag sorting roller assembly, so there is no need to set a material sensor. The baffle 41 can prevent the material from falling. Since the head end of the feeding roller assembly needs to cooperate with the feeding equipment, the baffle at this end cannot be set too high, and it is also difficult for the material to fall between the feeding equipment and the feeding roller assembly; and the baffles above the two sides are relatively high to prevent the material from splashing from both sides. In addition, in order to prevent the baffles on both sides from affecting the feeding, the baffles above the two sides of the feeding roller assembly are tilted outward from bottom to top to increase the receiving surface.

[0031] The bag sorting mechanism is tilted along its width direction, and a guide plate 23 is provided on the lower side, so that the material can be moved toward the side of the guide plate 23 under the action of gravity, so that all the materials can be transported along the same straight line to cooperate with the subsequent discharge roller assembly 5. The discharge end of the bag sorting mechanism is provided with a discharge roller assembly 5, and the discharge roller assembly 5 is arranged close to the guide plate 23. A screening channel 61 is provided on the side of the discharge roller assembly 5, and an identification device and a blow-off device 62 are provided above the screening channel 61. Among them, the width of the discharge roller assembly 5 is equivalent to the width of the bagged material. Therefore, when the bagged material can pass through the discharge roller assembly 5 normally along its length direction, and when the bagged material is in an inclined or horizontal state, when passing through the discharge roller assembly 5, part of it will extend above the screening channel 61, and be identified by the identification device, triggering the blow-off device 62, and blowing the bagged material into the screening channel 61. The identification device can generally adopt an image recognition device, and the blow-off device 62 can adopt a high-pressure pump to provide high-pressure gas.

[0032] In addition, the guide plate 23 is arranged near the middle of the frame, and accordingly, the two groups of discharge roller assemblies 5 on the same layer are located on opposite sides, the discharge end is more compact, and the screening channel 61 is located on the opposite side, thereby avoiding interference caused by the screening channels 61 being arranged opposite to each other.

[0033] In order to automatically separate the accidentally stacked materials, the bag sorting mechanism is tilted along its length direction, and the discharge end 22 is higher than the feed end 21, so that the materials stacked on top of other materials can slide down naturally under the action of gravity and vibration during the conveying process. In addition, when the upper materials slide down a part of the lower back, when passing through the two adjacent sets of bag sorting roller assemblies, the lower materials contact the upstream set of bag sorting roller assemblies, and the upper part of the materials sliding backwards contact the downstream set of bag sorting roller assemblies. Under the differential operation of the two sets of bag sorting roller assemblies, the stacked materials are easier to separate.

[0034] Finally, in order to facilitate the coordination between the bag sorting machine and the upstream and downstream equipment, the feeding end 21 and the discharging end 22 of the bag sorting mechanism are both extended out of the frame 1.

[0035] The above is only a preferred specific implementation of the utility model, which is a realization method based on the overall concept of the utility model, and the protection scope of the utility model is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
