Description

Technical field:

[0002] The invention relates to the field of automatic bag supply production line equipment, and mainly relates to a bag taking and discarding device for the automatic bag supply production line. Background technology:

[0004] Any automatic production line with an automatic bag supply device will fail to supply bags. If the bag supply fails, the automatic line will automatically discard the bag, and the bag will fall onto the platform of the bag supply machine. At this time, the entire production line will wait for the discarded bag to be taken away manually before it can work normally, otherwise it will affect the supply of the next bag. At present, it is taken manually. Although it can be timely, the mechanical equipment is relatively closed, and it is very dangerous and time-consuming to take the bag, which increases the labor intensity of the manual labor and cannot meet the needs of automated production and processing. Summary of the invention:

[0006] The purpose of the present invention is to make up for the defects of the existing technology and provide a bag picking and discarding device for an automatic bag supply production line. Through the cooperation of the detection probe, the grabbing mechanism and the swing cylinder, the material bags can be automatically picked up and shifted. No manual participation is required in the process, which not only avoids the safety hazards when manually picking up and discarding bags, but also reduces the labor intensity, saving time and effort.

[0007] The present invention is achieved through the following technical solutions:

[0008] A bag picking and discarding device for an automatic bag supply production line, characterized in that it includes an installation shell, a transmission mechanism is installed on one side of the installation shell, the transmission mechanism includes a vertical rotating shaft and a swinging cylinder that drives the rotating shaft to rotate, a transmission plate is installed on the rotating shaft, the extended end of the piston rod of the swinging cylinder is connected to the transmission plate, a grabbing arm is connected to the rotating shaft through a fixed handle, a probe mounting plate is provided at the front end of the grabbing arm, a probe is installed on the probe mounting plate, a grabbing mechanism is installed at the front end of the grabbing arm, the grabbing mechanism includes a fixed seat, a rotating shaft is installed in the fixed seat, a flippable gripper is installed on the rotating shaft through a sleeve, and the flipping of the gripper is driven by the grabbing cylinder behind it.

[0009] The mounting shell is composed of a cylinder fixing seat and a shell. The two ends of the rotating shaft are rotatably mounted on the shell through seat bearings, and the end of the shell is provided with a mounting hole for connecting to an automatic bag feeding machine. The swing cylinder is mounted on the cylinder fixing seat at the other end of the shell through a pin shaft.

[0010] The transmission plate is an arc-shaped plate, which is fixedly sleeved on the first rotating shaft, and the extended end of the piston rod of the swing cylinder is connected to the transmission plate through a joint.

[0011] The fixing seat is composed of side plates, baffle plates and a bottom plate. The side plates are located on both sides of the bottom plate. The baffle plate is tilted and located between the two side plates in front, and there is a gap between the baffle plate and the bottom plate. The front end of the bottom plate is an oblique cone surface.

[0012] The gripper is rotatably mounted on the second rotating shaft through a shaft sleeve, and a plurality of claw bodies with a C-shaped cross-section are distributed on the gripper, and the two ends of the second rotating shaft are fixedly mounted on the mounting grooves of the base plate, and a joint is installed at the protruding end of the piston rod of the gripping cylinder, and the joint is connected to the arc section of the claw body at the mounting end of the gripper through a fixed pin shaft, and the other end of the gripper is a gripping end, and guide grooves corresponding to each claw body are distributed on the baffle plate, and a notch is provided between the baffle plate and the base plate, and the gripping end passes through the guide groove and cooperates with the base plate at the notch to achieve gripping.

[0013] The grabbing cylinder is fixedly mounted on the rear end of the bottom plate through a connecting plate, and the connecting plate is fixedly mounted on the side plates on both sides thereof.

[0014] The principle is: when the control of the automatic line sends out a bag abandonment signal, the swing cylinder is started to drive the rotating shaft to rotate, thereby driving the grabbing arm to move to the bag abandonment position, and the probe on the probe mounting plate at the front end of the grabbing arm is used to detect whether there is a discarded material bag. If so, the bag taking cylinder on the bag taking mechanism is actuated, driving it to rotate around the rotating shaft and cooperate with the bottom plate to grab the material bag, and then move it to the specified position through the action of the swing cylinder. If the bag is abandoned again as the production progresses, the above operation can be repeated; in the whole process, no manual participation is required, which not only avoids the safety hazards when manually picking up the discarded bags, but also reduces the labor intensity, saves time and effort, and meets the requirements of automated batch bagging.

[0015] The advantages of the present invention are:

[0016] The present invention has a reasonable structural design. Through the cooperation of the detection probe, the grasping mechanism and the swing cylinder, the material bag can be automatically picked up and shifted. No human intervention is required in the process, which not only avoids the safety hazards when manually picking up and discarding the bags, but also reduces the labor intensity, saves time and effort, and meets the requirements of automated batch bagging.
