Problems solved by technology

[0003] In the prior art, when realizing the connection of two rolls of material, the material is usually connected automatically by detecting the rotation speed of the roll material or the roll diameter of the roll material. When the detection speed or roll diameter of the roll material reaches the set value, start the material cutting mechanism and the material receiving mechanism to realize the splicing of the tail of the first reel material and the head of the second reel material. The problem of such material splicing is that the first reel will There will be 30-40 meters of coiled material left in the material, and the remaining coiled material can only be wasted in vain, and the production cost is high

Embodiment 1

[0050] like figure 1 Shown, the automatic splicing method of the coil end of the present embodiment, it comprises the following steps:

[0051] Step (1), when winding the coiled material, attach the tail mark at the position of the coiled material 5m away from the end of the coiled material, and stick the double-sided adhesive tape 10 and the joint mark on the coiled material’s head;

[0052] Step (2) includes the following steps:

[0053] Step A, respectively install the coils on the first unwinding mechanism 1 and the second unwinding mechanism 2; set the parameters of the PLC controller, start the first unwinding mechanism 1, and realize it through the first material traction mechanism 31 The coiled material of the first unwinding mechanism 1 is punched and shaped in the finished product conveying mechanism 6;

[0054] Step B, start the joint detector 7, when the joint detector 7 detects the joint mark, the joint detector 7 sends a signal to the PLC controller, and the PL...

Embodiment 2

[0081] The difference between this embodiment and Embodiment 1 is that the first mark detector in this embodiment includes a first material end mark detector 12, and the second mark detector includes a second material end mark detector 22, so Both the first tail mark detector 12 and the second tail mark detector are camera systems. When in use, when the camera system detects the tail mark, the signal is sent to the PLC controller, and the PLC controller starts the first unwinding mechanism 1, the second unwinding mechanism 2, the material cutting mechanism 4, the material receiving mechanism 5 and The finished product conveying mechanism 6, etc. realizes the automatic material receiving of the coil and discharges the finished product with the joint mark or the end mark. The operation is simple, and the detection accuracy of the camera system is higher and the detection is accurate.

[0082] The automatic splicing method of the coil end of the present embodiment, it comprises t...

Embodiment 3

[0094] like figure 1 As shown, the automatic material splicing method of the coil end of the present embodiment comprises the following steps:

[0095] Step (1), when winding the coiled material, affix the tail mark at the position 2m away from the end of the coiled material, and affix the double-sided adhesive tape 10 and the joint mark at the head of the coiled material;

[0096] Step (2) includes the following steps:

[0097] Step A, respectively install the coils on the first unwinding mechanism 1 and the second unwinding mechanism 2; set the parameters of the PLC controller, start the first unwinding mechanism 1, and realize it through the first material traction mechanism 31 The coiled material of the first unwinding mechanism 1 is punched and shaped in the finished product conveying mechanism 6;

[0098] Step B, start the joint detector 7, when the joint detector 7 detects the joint mark, the joint detector 7 sends a signal to the PLC controller, and the PLC controlle...

Abstract

The present invention relates to the technical field of automatic splicing methods, in particular to an automatic splicing method at the end of a coil, comprising the following steps: attaching a tail mark to the end of the coil, and pasting a double-sided adhesive tape and a joint mark on the head of the coil , when the mark detector detects the tail mark, the PLC controller controls the coil material of the first unwinding mechanism and the coil material of the second unwinding mechanism to automatically pick up materials; when the mark detector detects the joint mark, the PLC controller Control the defective product discharge mechanism to discharge the finished products with joint marks. The invention can realize coil end detection, automatic splicing of two coils and discharge of defective products, realize maximum utilization of coil raw materials, waste coil raw materials from tens of meters to several meters or even tens of centimeters, and reduce It reduces 80-99% loss of coil raw materials, which greatly saves production costs. At the same time, it can smoothly discharge finished products with joint marks, with a high degree of automation and high processing efficiency.

Description

technical field [0001] The invention relates to the technical field of automatic material splicing methods, in particular to an automatic material splicing method at the end of a coil. Background technique [0002] The automatic feeding device is a device used in the production line of disposable sanitary products or paper making. Its main function is to prepare the second roll of material when the first roll of material is about to run out. It can realize the smooth connection of the two rolls of materials under the circumstances, and it can meet the splicing and splicing of the continuous roll materials when changing the material at any position. [0003] In the prior art, when realizing the connection of two rolls of material, the material is usually connected automatically by detecting the rotation speed of the roll material or the roll diameter of the roll material. When the detection speed or roll diameter of the roll material reaches the set When the value is set, st...
