Description

Paper roll conveying device

technical field

The invention relates to the technical field of wallpaper automatic production, in particular to a paper roll conveying device.

Background technique

In the production process of wallpaper, due to the differences in size and height among various equipment, it is difficult to pack wallpaper paper rolls directly after printing. In most cases, they are divided into small rolls and then packaged. This will involve a transfer and delivery of wallpaper. For example, a large roll of wallpaper paper needs to be transported to the splitting machine to be divided into several small rolls, and then the small rolls are transferred to the packaging equipment. During the transfer process, the paper rolls often need to be turned around. At this time, we often need to use some conveying devices, otherwise we must rely on manual work to complete this work.

At present, most wallpaper manufacturers rely on human hands to complete the transportation and transfer of paper rolls. Only a very small number of manufacturers have used some lifting and transferring pneumatic conveying devices. Although these devices have realized the automatic conveying function to a certain extent, there are still some problems such as easy to fall, easy to get stuck, strong impact and vibration, and failure rate. Problems such as height will cause a lot of product loss during use, which will affect the performance of the whole line.

Wherein the support is the structural foundation of the whole device, and its effect is to install for other mechanisms. The support includes a horizontal beam 61, and the length direction of the horizontal beam 61 is the transmission direction of the paper roll conveying device. The translation part 2 is arranged on the horizontal beam 61, and the translation driving mechanism 1 is also arranged on the horizontal beam 61 and connected with the translation part 2. When the translation driving mechanism 1 works, the translation part 2 can be driven to slide along the horizontal beam 61.

When the rotation drive mechanism 3 is working, the rotation part 4 can be driven to rotate, and the rotation of the rotation part 4 is roughly in the horizontal plane The internal rotation is the rotation with a roughly vertical axis as the central axis. The handle 5 is arranged on the rotating member 4, and when the rotating member 4 rotates, the handle 5 rotates with it. Since the U-turn of the paper roll needs to turn over 180 degrees, the angle at which the rotating drive mechanism 3 drives the rotating member 4 to turn over every time is 180 degrees.

There are two horizontal beams 61 in the bracket, and the two horizontal beams 61 are arranged in parallel and spaced apart from each other, and the spaced distance is greater than the total width of the rotating member 4 plus the handle 5 . The bracket also includes two front columns 62 and two rear columns 63, the two front columns 62 are respectively fixed on the front ends of the two horizontal beams 61 and supported on the ground, and the two rear columns 63 are respectively fixed on the rear ends of the two horizontal beams 61 and supported on the ground. The translation piece 2 is connected between two horizontal beams 61, and the two horizontal beams 61 are respectively provided with a translation drive mechanism 1, and the two translation drive mechanisms 1 are respectively connected with the two ends of the translation piece 2 to drive the translation piece 2 on the two horizontal beams 61.

The gear 33 is rotatably arranged on the translation member 2 and meshes with the rack 32. When the rack 32 moves, the gear 33 is driven to rotate. In this embodiment, the rotating member 4 is roughly in an inverted right-angle U-shaped structure, and its position is located below the middle position of the translation member 2. The gear 33 is fixed to the rotating member 4 through a rotating shaft. When the gear 33 rotates, the rotating member 4 also rotates. . It has been mentioned above that the required rotation angle of the rotating member 4 is 180 degrees, so the amount of extension of the piston rod 311 needs to be sufficient to just rotate the gear 33 and the rotating member 4 through 180 degrees. In other embodiments, other mechanisms other than the rack and pinion may also be used to drive the rotating member 4 to rotate, such as a motor and a reducer.

The translation part 2 moves above the paper roll on the horizontal beam 61, and then the lifting cylinder 6 pushes the gripper 5 downward to make the gripper 5 close to the paper roll. When the gripper 5 reaches the grabbing position, the gripper 5 closes to grasp the paper roll. live. After the grabbing is successful, the translation piece 2 moves toward the rear end of the support. When reaching a predetermined position, such as the middle position of the horizontal beam 61 (which can be sensed by timing, step counting, or sensor positioning), the cylinder 31 starts to make the rotating piece 4 , gripper 5 and the paper roll turn over 180 degrees to complete the U-turn of the paper roll. When the translation part 2 moves above the conveying platform 8, the lift cylinder 6 drives the gripper 5 close to the conveying platform 8, the gripper 5 opens and the paper roll is placed or falls on the conveying platform 8, completing the transfer of the paper roll. The heights of the conveying platform 8 and the positioning platform 7 can be the same or different, and the height position control of the gripper 5 can be realized by using the lifting cylinder 6 .
