Description

Technical Field

[0001] This utility model relates to the field of soft bag product manufacturing technology, and in particular to a soft bag sorting device. Background Technology

[0002] In the production of soft bags, the finished soft bags need to be inspected by light, wrapped, and packaged. Before this, the soft bags are usually arranged neatly by manual material cutting, which consumes a lot of manpower and has low sorting efficiency.

[0003] Utility model patent document with authorization announcement number CN2196697U discloses a soft bag sorting device. Its technical solution includes a frame and a feeding mechanism, a feeding conveying mechanism, a cornering mechanism, a differential conveying mechanism and a discharging mechanism installed on the frame. The conveying direction of the feeding conveying mechanism is opposite to the conveying direction of the differential conveying mechanism. The differential conveying mechanism includes a barrier wall and multiple roller conveying groups installed on the barrier wall and arranged in sequence. Each roller conveying group includes a servo drive, a gear transmission assembly and multiple rollers. The servo drive is installed on the back of the barrier wall and is poweredly connected to the gear transmission assembly. The rollers are rotatably installed on the barrier wall. One end of the roller is connected to the gear transmission assembly, and the other end extends through the barrier wall to the front of the barrier wall. Although the technical solution of this utility model can sort the soft bags during the conveying process, the principle of sorting the soft bags is to use a sorting device to turn the upright soft bags into a flat state, and to use multiple roller conveying groups of differential speed conveying mechanism to control the speed of each soft bag. Each roller conveying group is independently controlled and operates independently. Therefore, the bag sorting mechanism is relatively complex and the cost of the whole device is high. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a soft bag sorting device that can automatically sort soft bags after feeding and has a relatively simple bag sorting mechanism.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a soft bag sorting device, including a conveying mechanism and a bag-tapping mechanism; the conveying mechanism is used to convey soft bags, and the two ends of the conveying mechanism are the inlet end and the outlet end, respectively; at least one bag-tapping mechanism is set on the conveying path of the conveying mechanism, and the bag-tapping mechanism is provided with a reciprocating lifting and lowering material distribution plate, the material distribution plate is inclined so that the lifting and lowering direction of the material distribution plate is inclined to the conveying direction of the soft bag, and the height of the end of the material distribution plate near the inlet end is higher than the height of the end near the outlet end.

[0006] As a further improvement to the above solution: the bag-tapping mechanism also includes an mounting plate, a fixing plate, and a lifting drive cylinder; the fixing plate is suspended above the conveying mechanism by two mounting plates that are respectively vertically fixed on both sides of the conveying mechanism, and the lifting drive cylinder is fixedly mounted on the fixing plate, with the output end of the lifting drive cylinder fixedly connected to the material distribution plate.

[0007] As a further improvement to the above solution: the bag-tapping mechanism also includes a height adjustment module; the height adjustment module includes a mounting base, a drive screw, a sliding block, and a guide rod; the mounting base is fixedly mounted on a fixed plate, the drive screw is rotatably mounted on the mounting base, the sliding block is threadedly engaged with the drive screw, the lifting drive cylinder is fixed on the sliding block, and the guide rod is fixed on the mounting base and passes through the sliding block, with a clearance fit between the guide rod and the sliding block.

[0008] As a further improvement to the above solution: the bag-tapping mechanism also includes an adjusting head and a locking head; the adjusting head is fixedly connected to the drive screw, and the locking head is threadedly engaged with the mounting seat through a screw, with the screw end of the locking head radially abutting against the drive screw.

[0009] As a further improvement to the above solution: the mounting plate is provided with at least one adjustment groove, which is an arc-shaped groove; it also includes an adjustment screw that passes through the adjustment groove and is threadedly connected to the end of the fixing plate, and the end of the fixing plate is rotatably connected to the mounting plate through a rotating shaft.

[0010] As a further improvement to the above solution: the mounting plate is provided with two adjustment slots, which are symmetrically arranged with the rotating shaft as the center.

[0011] As a further improvement to the above scheme: the bag-tapping mechanism is set to at least two, and the at least two bag-tapping mechanisms are evenly distributed at intervals along the conveying direction of the conveying mechanism.

[0012] As a further improvement to the above solution: the conveying mechanism consists of multiple conveyor belts that are connected sequentially, each conveyor belt is equipped with a position sensor, and the conveying speed of each conveyor belt is independently controlled.

[0013] As a further improvement to the above scheme, it also includes two guardrails set near the feed end of the conveying mechanism. The guardrails extend along the conveying direction of the conveying mechanism, and there is a gap between the two guardrails with a width greater than the width of the soft bag. The opposite surfaces of the two guardrails are flat.

[0014] As a further improvement to the above solution, it also includes a mounting frame and a connecting plate. The mounting frame is detachably fixed to the conveying mechanism. The mounting frame is provided with a groove parallel to the width direction of the conveying mechanism. The opposite sides of the two guardrails are provided with a slide rail extending along the length direction of the guardrail. The connecting plate is connected between the mounting frame and the guardrail. The two ends of the connecting plate are respectively in sliding cooperation with the groove of the mounting frame and the slide rail of the guardrail.

[0015] The beneficial effects of this utility model are as follows: By setting a bag-tapping mechanism on the conveying mechanism of the soft bags, the inclined material distribution plate on the bag-tapping mechanism taps the soft bags multiple times through reciprocating lifting motion, causing the stacked soft bags to gradually separate and spread out on the conveying mechanism.

This utility model can realize automatic bag sorting after the soft bags are fed in, so that the stacked soft bags are neatly arranged before being discharged. The bag sorting process does not require manual intervention, effectively reducing the intensity of manual labor and improving production efficiency. Attached Figure Description

Detailed Implementation

[0018] To facilitate understanding of this utility model, the following description, in conjunction with the accompanying drawings, will provide further details.

[0019] In the description of this utility model, it should be noted that the terms "front", "rear", "left", "right", "up", "down", "inner", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of description and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figure 1 As shown, the soft bag sorting device disclosed in this utility model includes a conveying mechanism 100 and a bag-tapping mechanism 200; the conveying mechanism 100 is used to convey soft bags 300, and the bag-tapping mechanism 200 separates overlapping soft bags 300 during the conveying process by tapping the soft bags 300.

[0021] Specifically, such as Figure 1 and Figure 3As shown, the conveying mechanism 100 in this invention has an inlet and an outlet, respectively. The inlet of the conveying mechanism 100 is used to feed the soft bags 300. When feeding, only the orientation of the head of the soft bag 300 needs to be considered, ensuring that the head of the soft bag 300 faces the outlet of the conveying mechanism 100. The soft bags 300 are stacked one after another, with the head of the next soft bag 300 pressing on the head of the previous soft bag 300. This invention provides guardrails 510 on the conveying mechanism 100. By installing two guardrails 510, limiting constraints are formed on both sides of the soft bag 300. The guardrails 510 extend along the conveying direction of the conveying mechanism 100. The two guardrails 510 are spaced apart in the width direction of the conveying mechanism 100 to form a gap between them as a channel for the soft bags 300 to pass through. The width of the gap between the two guardrails 510 is slightly larger than the width of the soft bag 300. The opposite surfaces of the two guardrails 510 are both set as planes. The guardrail 510 is fixed and will not move with the conveying mechanism 100. When the soft bag 300 passes through the channel between the two guardrails 510, the opposite surfaces of the two guardrails 510 will block and limit the soft bag 300 to prevent it from shifting during the conveying process, so that the soft bag 300 keeps its head facing forward and achieves the initial sorting of the soft bag 300.

[0022] like Figure 1 and Figure 3As shown, the guardrail 510 in this utility model is mounted on the conveying mechanism 100 via a mounting bracket 520 and a connecting plate 530. The mounting frame 520 is a frame structure composed of two side plates and a middle plate. The two side plates of the mounting frame 520 are fixedly connected to the conveying mechanism 100, so that the middle plate of the mounting frame 520 is suspended above the conveying mechanism 100. A groove 521 parallel to the width direction of the conveying mechanism 100 is provided on the middle plate of the mounting frame 520. A slide rail 511 extending along the length direction of the guardrail 510 is provided on the opposite sides of the two guardrails 510. A connecting plate 530 is connected between the mounting frame 520 and the guardrail 510. The two ends of the connecting plate 530 are respectively slidably engaged with the groove 521 of the mounting frame 520 and the slide rail 511 of the guardrail 510. The connection between the connecting plate 530 and the mounting frame 520 and the connection between the connecting plate 530 and the guardrail 510 can be achieved by bolts. Loosening the bolts allows the connecting plate 530 to slide along the groove 521 or along the slide rail 511, and tightening the bolts fixes the connecting plate 530. The guardrail 510 is fixed to the mounting frame 520 by the connecting plate 530, so that the guardrail 510 does not directly contact the conveying mechanism 100. By adjusting the position of the connecting plate 530 in the slide groove 521, the distance between the two guardrails 510 can be changed, so that this utility model can be applied to soft bags 300 of different specifications. By adjusting the position of the connecting plate 530 in the slide rail 511, the extension length of the guardrail 510 can be changed, so that the guardrail 510 can be extended to cooperate with the bag knocking mechanism 200, and multiple guardrails 510 can be assembled to extend the overall length.

[0023] The number of bag-tapping mechanisms 200 can be set according to actual work requirements. In this utility model, at least two bag-tapping mechanisms 200 are set, and the at least two bag-tapping mechanisms 200 are evenly distributed at intervals along the conveying direction of the conveying mechanism 100.

[0024] Specifically, such as Figure 1 and Figure 2As shown, the bag-tapping mechanism 200 used in this utility model includes a material distribution plate 210, a mounting plate 220, a fixing plate 230, and a lifting drive cylinder 240. The material distribution plate 210 is used to sort the soft bags 300. The mounting plate 220 and the fixing plate 230 are used to install the lifting drive cylinder 240, which drives the material distribution plate 210 to perform reciprocating lifting motion. The two mounting plates 220 of the bag-tapping mechanism 200 are vertically fixed on both sides of the conveying mechanism 100, and the fixing plate 230 is connected between the two mounting plates 220, so that the fixing plate 230 is suspended above the conveying mechanism 100. The lifting drive cylinder 240 is mounted on the fixing plate 230, and the material distribution plate 210 is fixedly connected to the output end of the lifting drive cylinder 240. The material distribution plate 210 needs to be kept in an inclined state. This is achieved by fixing the fixing plate 230 to the mounting plate 220 at an incline, thereby tilting the lifting drive cylinder 240 fixed on the fixing plate 230. The material distribution plate 210 can then be tilted under the drive of the lifting drive cylinder 240. Driven by the lifting drive cylinder 240, the material distribution plate 210 can reciprocate in a lifting motion. The height of the end of the material distribution plate 210 near the inlet is higher than the height of the end near the outlet, causing the lifting direction of the material distribution plate 210 to be tilted relative to the conveying direction of the soft bag 300, forming a certain angle between the two. During the conveying process of the soft bag 300, the bag-tapping mechanism 200 taps the soft bag 300 below multiple times through the reciprocating lifting motion of the material distribution plate 210, blocking the soft bag after the previous soft bag from pressing on the previous soft bag, so that the previous soft bag continues to be conveyed forward and the next soft bag is detached from the previous soft bag. After multiple taps by the material distribution plate 210, the stacked soft bags 300 are laid flat on the conveying mechanism 100.

[0025] Furthermore, in order to adjust the striking height of the bag-tapping mechanism 200, the bag-tapping mechanism 200 of this utility model is also equipped with a height adjustment module. For example... Figure 2As shown, the height adjustment module includes a mounting base 410, a drive screw 420, a sliding block 430, and a guide rod 440. The mounting base 410 is fixedly mounted on the fixed plate 230. The two ends of the drive screw 420 are rotatably mounted on the mounting base 410 via bearings. The sliding block 430 is threadedly engaged with the drive screw 420. The lifting drive cylinder 240 is fixed to the sliding block 430. The guide rod 440 is fixed to the mounting base 410 and passes through the sliding block 430, with a clearance fit between the guide rod 440 and the sliding block 430. By rotating the drive screw 420, the threaded sliding block 430 can be raised and lowered along the drive screw 420. The guide rod 440 is used to prevent the sliding block 430 from rotating and to guide the raising and lowering action of the sliding block 430, ensuring that the raising and lowering of the sliding block 430 proceeds normally. The raising and lowering action of the sliding block 430 will drive the lifting drive cylinder 240 fixedly connected to it to raise and lower synchronously, thereby realizing the adjustment of the height of the material distribution plate 210. The bag-tapping mechanism 200 also includes an adjusting head 450 and a locking head 460. The adjusting head 450 is fixedly connected to the drive screw 420, and the locking head 460 is threadedly engaged with the mounting base 410 via a screw. The screw end of the locking head 460 radially abuts against the drive screw 420. The adjusting head 450 facilitates the rotation of the drive screw 420, and rotating the adjusting head 450 adjusts the height of the material distribution plate 210. The locking head 460 locks the drive screw 420. After the height of the material distribution plate 210 is adjusted, tightening the locking head 460 will press and lock the drive screw 420 to prevent it from rotating.

[0026] Furthermore, in order to adjust the striking angle of the bag-tapping mechanism 200, such as... Figure 2 As shown, this utility model provides an adjustment groove 221 on the mounting plate 220, the adjustment groove 221 being an arc-shaped groove; the two ends of the fixing plate 230 are rotatably connected to the two mounting plates 220 respectively via rotating shafts, and adjusting screws 222 are threadedly connected to the two ends of the fixing plate 230. The adjusting screws 222 pass through the corresponding adjustment grooves 221. By turning the adjusting screws 222, the fixing plate 230 can be locked onto the mounting plate 220 to achieve fixation of the fixing plate 230. After loosening the adjusting screws 222, the adjusting screws 222 can slide in the adjustment grooves 221, thereby adjusting the tilt angle of the fixing plate 230, ultimately achieving adjustment of the tilt angle of the material distribution plate 210. To improve the connection stability between the fixing plate 230 and the mounting plate 220, two adjustment grooves 221 can be provided on the mounting plate 220, the two adjustment grooves 221 being symmetrically arranged around the rotating shaft.

[0027] After being tapped and arranged by the bag-tapping mechanism 200, although the soft bags 300 can be laid flat on the conveying mechanism 100, the spacing between adjacent soft bags 300 is uneven. Therefore, the soft bags 300 need to be further arranged to ensure that they are evenly arranged on the conveying mechanism 100. Figure 1 As shown, this utility model employs multiple sequentially connected conveyor belts to form a conveyor mechanism 100. Each conveyor belt is equipped with a servo motor to independently control its conveying speed, and a position sensor is installed on each conveyor belt to monitor the real-time position of the soft bags 300. This utility model maintains a uniform spacing between the soft bags 300 by controlling the conveying speed of each conveyor belt. Figure 1 For example, the conveying mechanism 100 in this utility model uses a four-section conveyor belt; the first section of the conveyor belt is used for feeding the soft bags 300, so the conveying speed is set to be relatively slow; the second section of the conveyor belt is used to cooperate with the bag-tapping mechanism 200, and the soft bags 300 are tapped multiple times during the conveying process through the relatively slow conveying speed; the conveying speed of the third section of the conveyor belt is greater than that of the second section of the conveyor belt. After the soft bags 300 pass through the hinge position of the second and third section of the conveyor belt, the third section of the conveyor belt will quickly convey the soft bags forward due to the increased conveying speed, so that the soft bags 300 arranged in front and behind are spaced apart; the fourth section of the conveyor belt is set as a conveyor belt group composed of multiple sections of the conveyor belt. The spacing between the soft bags 300 is adjusted by changing the speed of each section of the conveyor belt group so that each soft bag 300 is conveyed with a uniform spacing until it is conveyed to the discharge end of the conveying mechanism 100 for unloading.
