Packaging host equipment outlet anti-blocking device

Abstract

The present invention discloses an anti-blocking device for the outlet of a packaging host device. The main design concept of the present invention is that once the conveyor belt is blocked, the detector arranged on the conveyor belt can output an abnormal signal to the original machine controller, thereby triggering the cigarette package to stop conveying and controlling the rejection mechanism to reject and recycle the congested cigarette package from the output wheel of the packaging host. At the same time, the alarm can be triggered to prompt the operator to pay attention to the blockage situation, so as to avoid the continuous output of cigarette packages and the accumulation of cigarette packages on the conveyor belt due to the movement inertia of the output of the packaging host device, thereby damaging the equipment and products. The present invention can effectively avoid accumulation and congestion in the process from the packaging host device to the conveyor belt, while protecting the cigarette packages and equipment, saving production costs and improving equipment operation efficiency.

Description

Technical Field

[0001] The invention relates to the field of cigarette manufacturing, and in particular to an anti-blocking device for an outlet of a packaging host device. Background Art

[0002] In the production process of GD series packaging equipment, small cigarette packs wrapped with aluminum paper, cardboard or seals and trademarks are output from the outlet of the packaging main equipment, and then enter the packaging auxiliary equipment through the conveyor belt to complete the subsequent packaging processes such as transparent paper.

[0003] However, due to various factors, the cigarette packs on the conveyor belt may be blocked, which in turn causes the cigarette packs to be blocked at the outlet of the packaging host equipment. The packaging equipment continues to operate when the cigarette packs are blocked, causing a large number of cigarette packs conveyed by the packaging host equipment to accumulate and clog at the entrance of the conveyor belt, resulting in serious obstruction at the outlet of the packaging host equipment.

[0004] Although the output wheel at the outlet of the current packaging host equipment is equipped with a clutch, due to inertia, the packaging host equipment cannot be shut down instantly and reliably. In actual applications, the output wheel at the outlet of the packaging host equipment will still be damaged and the cigarette packs will be damaged. Not only does it require the equipment to be shut down for repair, but it will also bring about a large cost loss. Summary of the invention

[0005] In view of the above, the present invention aims to provide an anti-blocking device for the outlet of a packaging host device, so as to solve the aforementioned technical problems.

[0007] The present invention provides an anti-blocking device for the outlet of a packaging host device, which comprises: a cigarette pack detector, a rejection mechanism, a cigarette pack recovery box and an alarm;

[0008] The cigarette pack detector is installed on the side guard plate of the cigarette pack conveyor belt, the rejection mechanism is installed below the output wheel of the packaging host device outlet, the cigarette pack recovery box is located below the rejection mechanism for receiving and recovering the rejected cigarette packs, and the alarm is provided on the packaging host device;

[0009] The cigarette pack detector, the rejecting mechanism and the alarm are respectively connected to the original machine controller of the packaging host device through electrical signals.

[0010] In at least one possible implementation, the number of the cigarette pack detectors is at least two, and they are respectively installed on the side guard plates on both sides of the cigarette pack conveyor belt.

[0011] In at least one possible implementation manner, the distance between the installation position of the cigarette packet detector and the output wheel is set to be 3 to 5 cigarette packet lengths.

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described below with reference to the accompanying drawings, in which:

[0019] Figure 1 A schematic diagram of the structure of an anti-blocking device for an outlet of a packaging host device provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0020] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0021] The present invention proposes an embodiment of an anti-blocking device for an outlet of a packaging host device. Specifically, Figure 1As shown, it includes a cigarette pack detector 1, a rejection mechanism 2, a cigarette pack recovery box 3 and an alarm 4; wherein the cigarette pack detector 1 is installed on the side guard plate of the cigarette pack conveyor belt 100, the rejection mechanism 2 is installed below the output wheel 300 at the outlet of the packaging host device 200, the cigarette pack recovery box 3 is located below the rejection mechanism 2 for receiving and recovering the rejected cigarette packs 400, and the alarm 4 is arranged on the packaging host device 200;

[0022] The cigarette pack detector 1, the rejection mechanism 2 and the alarm 4 are respectively connected to the original machine controller of the packaging host device (not shown in the figure, reference may be made to the existing and mature electrical control technology, which will not be repeated or limited here) by electrical signals.

[0023] Furthermore, the number of the cigarette pack detectors 1 is at least two, and they are respectively installed on the side guard plates on both sides of the cigarette pack conveyor belt 100 .

[0024] Furthermore, the distance between the installation position of the cigarette pack detector 1 and the output wheel 300 is set to be 3 to 5 cigarette pack lengths.

[0025] Furthermore, the rejection mechanism 2 includes an electrically controlled flap and an arc-shaped guide channel connected to the lower part of the electrically controlled flap.

[0026] Furthermore, a buffer component is provided inside the cigarette pack recovery box 3 .

[0027] Furthermore, the buffer component includes a cushion.

[0028] Furthermore, the cigarette packet detector 1 includes a photoelectric sensor.

[0029] Furthermore, the alarm 4 includes a visual alarm, a sound alarm and / or an acousto-optic alarm.

[0030] In summary, the working principle of the present device is schematically described as follows: under normal production conditions, the cigarette pack detector continuously detects the cigarette packs that are transported at intervals. Once congestion occurs, the feedback signal of the cigarette pack detector changes. At this time, the original machine controller can trigger the equipment to shut down and / or alarm. At the same time, it can also trigger the removal mechanism to make the accumulated cigarette packs fall into the recovery box below. This can prevent the cigarette packs from being continuously transmitted to the conveyor belt and accumulated with the cigarette packs that are blocking the conveyor belt.

[0031] In summary, the main design concept of the present invention is that once the conveyor belt is blocked, the detector arranged on the conveyor belt can output an abnormal signal to the original machine controller, thereby triggering the cigarette package to stop conveying and controlling the rejection mechanism to reject and recycle the blocked cigarette package from the output wheel of the packaging host. At the same time, the alarm can be triggered to prompt the operator to pay attention to the blockage situation, so as to avoid the continuous output of cigarette packages and the accumulation of cigarette packages on the conveyor belt due to the inertia of the movement output by the packaging host device, thereby damaging the equipment and products. The present invention can effectively avoid accumulation and congestion in the process from the packaging host device to the conveyor belt, while protecting the cigarette packages and equipment, saving production costs and improving equipment operation efficiency.
