Problems solved by technology

[0003] Traditionally, in order to adapt to the variation of the nail pitch caused by different box sizes, it is necessary to adjust the swing amplitude of the nail head 1. However, this swing amplitude adjustment usually requires manual adjustment, which is time-consuming and requires multiple adjustments to achieve the nail pitch. Requirements, and low precision, poor flexibility

Embodiment Construction

[0012] For the traditional nail box machine, in the process of nail box operation through the reciprocating swing of the nail head, since the swing amplitude has been designed in advance according to the traveling speed of the conveyor belt to match the specific nail distance requirements, the nail head swings at a fixed angular speed during the whole process . To this end, one cycle of the nail head's oscillation can be modeled as a circular motion, such as figure 2 As shown, the actual completion of a nail box operation by the nail head can be simulated as a round cutting operation of the cutting knife on the strip moving forward on the conveyor belt. As shown in the figure, the length of each section of strip cut by the round corresponds to the nail distance D , that is, the circumference of the rotation of the cutter for one revolution (hereinafter also referred to as the die length) Lc. On the circle model shown in the figure, StartSyncAngle represents the synchronous s...

Abstract

The invention provides a nail head control method of a box nailing machine. The nail head control method comprises the steps that box parameters and nail head parameters are received; based on the boxparameters, the nail distance is determined; a cam mode for controlling a nail head to swing is generated based on the nail distance and the nail head parameters, the cam mode comprises a synchronousarea and an adjusting area, and the adjusting area is changed according to the nail distance; and in the synchronous area, the nail head and a conveying belt of a conveying box strip synchronously swing to finish the nailing operation. According to the nail head control method, the box nailing machine can adapt to different nail distance requirements by controlling the swing speed of the nail head under the condition of not changing the swing amplitude of the nail head.

Description

technical field [0001] The invention relates to a high-speed nail box machine, in particular to the swing control of the nail head of the nail box machine. Background technique [0002] With the rapid development of logistics e-commerce, the demand for corrugated boxes has also risen sharply, and carton manufacturers are also constantly updating equipment to improve production efficiency. In the carton production process, it is necessary to perform a stapling operation on the already glued box panels to form a complete box. In order to achieve the purpose of high-speed production of boxes, it is best not to stop carton production on the conveyor belt. During the binding process, the nail head of the nail box machine needs to be synchronized with the carton, so as to complete the continuous nail box operation. figure 1 A schematic diagram of the nail box operation is shown schematically. As shown in the figure, the box board advances at a constant speed along the direction ...
