Control device for packaging tubular materials

Abstract

The invention provides a control device for packaging tubular materials and relates to a packaging device for pillow type packages. Compared with a pillow type packaging method for the tubular materials, the conventional pillow type packaging method for sheet materials has the defects of material waste, non-attractive appearance, high material price, process increase, and energy consumption and labor cost increase. The invention provides the control device for controlling the packaging of the tubular materials by effectively matching relays, sensors and a controller. All the relays of the control device have a switch-on state and a switch-off state, each relay is connected with corresponding components; all the relays are connected with the controller; a detector consists of the sensors; the sensors are distributed on all the components and can detect and discriminate the current states of objects to be detected; all the sensors are connected with the controller; the sensors send sensing information to the controller; and the controller comprises electronic components and control procedures and can receive information of the sensors and send instructions to control the relays. The packaging device is used for tubular material packaging machines.

Description

Technical field: [0001] The invention relates to a control device, in particular to a control device for material packaging. Background technique: [0002] The existing pillow-type packaging method is to seal the sheet-shaped packaging material longitudinally to form a cavity with the left and right sides. At the same time, the items to be packaged are placed in the cavity, and then placed in the cavity. The cavity is sealed and cut off at both ends, because it looks like a pillow after packaging, so it is called pillow packaging. The whole packaging process has a high degree of automation and fast speed. It is suitable for lumpy, granular, powdery and liquid objects, such as biscuits, egg yolk pie, chocolate, bread, instant noodles, moon cakes, soy milk, milk, soy sauce, cooking wine, lotus root flour and other foods , As well as the packaging of various daily necessities, various industrial parts, various medical equipment and other objects. Many patents and expertise have bee...

AI Technical Summary

Problems solved by technology

[0003] This is an ideal form of pillow packaging, where the sheet material is sealed into a cavity structure, and the items to be packaged are placed in the cavity for packaging. However, the packaging of this form also has the following disadvantages: 1. Material waste, the existing pillow packaging machine is to pack after sewing the left and right sides of the sheet packaging material, and the sewing part will waste a lot of packaging Material

2. Affects the appearance, the stitched seam remains on the outside of the package and affects the appearance of the package

3. This form of technology requires the packaging material to be a multi-layer composite material, and the multi-layer composite material is expensive

4. Compared with the pillow packaging of tubular materials, it adds a process, increases labor costs and increases energy consumption

[0005] However, because of the packaging form of the tubular material, how to open the top end of the rolled tubular material, how to move the tubular material in the open state, how to ensure that the items to be packaged can enter the tubular material from the open end accurately, reliably and quickly, How to automatically form a new opening after the packaging is completed, how to keep the new opening in an open posture as required, etc., without corresponding control technology, cannot form an automated production flow operation

Therefore, the existing packaging form of tubular materials adopts manual operation in the opening and feeding operations, the work efficiency is not high, and it cannot meet the packaging requirements of items with high hygienic requirements.

[0006] Chinese patent 200820162608 The packaging bag support device of the automatic packaging machine for disposable syringes, the Chinese patent 2006100527142 The bag supporting mechanism of the bag-feeding packaging machine, 2008100634552 The solution proposed by the patents such as the packaging bag feeding device for the automatic packaging machine of disposable syringes method of control, no convincing description
