[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the following is a detailed description of the present invention in conjunction with the specific implementation methods and with reference to the attached drawings. Figure 1-4 , the utility model is further described in detail. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0021] The utility model provides a woven bag opening failure rejection mechanism, which includes a conveying plate 4 and a support frame 18. The conveying plate 4 is provided with a bag picking system, a feeding system, an opening system and a rejection system in sequence. The bag picking system includes a transverse moving cylinder 1, and the telescopic end of the transverse moving cylinder 1 is connected to a bag picking lifting cylinder 2. A bag picking suction cup 3 is provided at the bottom of the bag picking lifting cylinder 2. The initial position bag picking suction cup 3 is located above the position of the bag to be picked up. The bag picking lifting cylinder 2 drives the bag picking suction cup 3 to descend to suck up the bag to be picked up, and then the lifting cylinder 2 drives the bag picking suction cup 3 to rise. After the transverse moving cylinder 1 moves it to the opening system, it drives the lifting cylinder 2 to drive the woven bag on the bag picking suction cup 3 to fall, completes the work of picking up the bag and feeding, and then returns to the initial position to pick up the bag.

[0022] The opening system includes an upper suction cup lifting cylinder 17 installed on a support frame 18, the bottom of the upper suction cup lifting cylinder 15 is connected to the upper opening vacuum suction cup 7, and the conveying plate 4 is provided with a lower opening vacuum suction cup 8, and the lower opening vacuum suction cup 8 is arranged directly below the upper opening vacuum suction cup 7. The upper and lower ends of the woven bag are pulled by the upper opening vacuum suction cup 7 and the lower opening vacuum suction cup 8 to achieve the opening of the woven bag. The upper opening vacuum suction cup 7 and the lower opening vacuum suction cup 8 are both provided with a photoelectric system, which detects whether the upper opening vacuum suction cup 7 and the lower opening vacuum suction cup 8 open the woven bag or whether too much material is taken through the photoelectric system. When it is detected that the bag is not opened or too much material is taken, the photoelectric system transmits a signal to the control system, and the control system transmits a signal to the rejection system and the feeding system. The feeding system transmits the woven bag to the rejection system, and there is no need for manual picking up, which saves labor costs, avoids failure of operating equipment, and improves work efficiency.

[0023] The rejection system is connected to the rejection placement plate 6, which is arranged directly below the conveying plate 4 to rationally utilize the space and reduce the volume occupied by the equipment. The rejection system includes a rejection receiving unit 13, a photoelectric detection switch and a rejection receiving unit. The photoelectric detection switch 20 is arranged at the bottom of the end of the conveying plate 4. The photoelectric detection switch 20 is used to detect whether all unqualified woven bags are rejected. When the rejection is completed, the signal is transmitted to the control system, and the control system drives the rejection guide plate to fall.

[0024] The rejecting and receiving unit 13 and the feeding system are both transport components, and the transport components include a lower roller 5 rotatably mounted on the conveying plate 4, an upper pressing wheel lifting cylinder 17 is provided just above the lower roller 5, an upper pressing wheel 16 is rotatably mounted at the bottom of the upper pressing wheel lifting cylinder 17, and the lower roller 5 is connected to the lower roller driving motor group. When the opening fails, the upper pressing wheel descends under the action of the upper pressing wheel lifting cylinder and cooperates with the lower roller to transport the unqualified woven bags forward to the rejecting and receiving unit, and the rejecting and receiving unit transports them to the rejecting guide plate, such as Figure 3 shown.

[0025] The rejecting material receiving unit includes a rejecting guide plate 12 which is vertically slidably mounted on a guide support frame 10. The guide support frame 10 is provided with a sliding track 9. The rejecting guide plate 12 is provided with a sliding seat which always moves on the sliding track 9. The rejecting guide plate 12 is rotatably mounted on the rejecting lifting cylinder 11 at one end away from the conveying plate 4. The rejecting guide plate 12 is C-shaped and is used to change the conveying direction of the woven bags. The bottom of the rejecting lifting cylinder 11 is rotatably mounted on the rejecting placement plate. The rejecting guide plate 12 is driven up and down on the guide support frame by the rejecting lifting cylinder 11, so that when it is necessary to reject unopened or multiple woven bags, the woven bags can be transported to the rejecting placement plate along the rejecting guide plate, which is convenient and quick. Figure 4 shown.

[0026] First, the opening system uses A: the opening and closing distance of the upper and lower vacuum suction cups, B: diffuse reflection photoelectric detection on the upper and lower vacuum suction cups to see if the woven bag mouth is open, and C: the photoelectric detection of the outer sides of the upper and lower vacuum suction cups to see if there is a woven bag on the claws. These three detection measures are used to determine whether the opening system is successful.

[0027] In case one, when the system detects that the packaging bag fails to open, the rejection and pick-up system starts to work. First, the upper pressure wheel of the feeding system falls, and the packaging bag that fails to open is conveyed forward. At the same time, the rejection and pick-up unit rises to the front of the opening position, ready to receive the rejected packaging bag. When the rejection mechanism photoelectrically detects that the rejected packaging bag has reached the photoelectric detection position, the upper pressure wheel of the rejection receiving unit falls and continues to convey the rejected packaging bag forward. When the packaging bag reaches the rejection and pick-up unit, under the guidance of the C-shaped baffle of the conveying mechanism, the rejected packaging bag is conveyed to the rejection placement plate and stacked at the lower bag storage area. Figure 4 Until the rejection detection photoelectric device detects that the packaging bag has left the rejection mechanism, both sets of pressure wheels rise and return to their positions, and the rejection pick-up unit descends and returns to its position, completing the rejection work cycle of the packaging bag that failed to open.

[0028] In the second situation, when more than one packaging bag is taken out from the packaging bag warehouse at one time, the upper opening suction cup sucks the upper packaging bag and rises, and the bottom of the upper packaging bag sags under the action of gravity. The first packaging bag on the upper layer is opened successfully and then successfully put on the discharge port. However, the rejection detection switch still detects that there is a packaging bag at the opening position. At this time, the rejection system starts to work and rejects the packaging bag at the opening position to prepare for the transportation, opening and bagging of the next packaging bag.

[0029] Through the above structure, the packaging bags with unqualified opening or abnormal opening position can be removed to clear obstacles for the next bag opening work, thus ensuring the normal operation of the opening system.

[0030] When the detection mechanism detects that the packaging bag has reached the opening position but the state does not meet the requirements, or the packaging bag is not opened correctly during the opening process, or the opening and bagging are normal, but there are still packaging bags at the opening position, these situations will start the rejection mechanism to operate and reject the unqualified packaging bags.

[0031] When the utility model is in use, when it is detected that the woven bag is not opened or multiple woven bags are taken, the feeding system and the rejecting and receiving unit cooperate to feed the woven bag to the rejecting and receiving unit, thereby transferring the woven bag to the rejecting and placing plate. The present application is a mechanical device for rejecting unqualified packaging bags during the process of automatic bagging of packaging bags. It has a simple structure and stable operation. It effectively avoids the occurrence of bagging failure caused by unqualified packaging bag status during the automatic bagging process, improves the qualified rate of product packaging, avoids the occurrence of production quality accidents, and provides a strong guarantee for efficient automated production.
