Description

Technical Field

[0001] This utility model relates to the field of detection technology, specifically to an aluminum foil offset detection device. Background Technology

[0002] In the production process of the GDX1 packaging machine, aluminum foil rolls provide aluminum foil for wrapping cigarettes in molded boxes. The original machine detects aluminum foil offset by installing two fiber optic amplifiers, one inside and one outside, above the aluminum foil at the second-round inlet. This is used to detect the offset or presence / absence of the aluminum foil, as described in the utility model publication CN209410417U. However, this design can only detect offset or missing aluminum foil during the incoming process, but it cannot detect missing foil during wrapping. This results in situations where the aluminum foil is present upon arrival but offsets during wrapping, leading to low reliability. Furthermore, different cigarette models require different foil widths, and the detection device cannot adjust the detection position accordingly. To address these issues, this utility model provides an aluminum foil offset detection device. Utility Model Content

[0003] The purpose of this invention is to provide an aluminum foil offset detection device, which can detect the offset of aluminum foil during the wrapping process, improve the reliability of the detection, and adjust the detection position according to the width of aluminum foil required for different cigarette models.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An aluminum foil offset detection device includes a mold box wheel, which is rotatably mounted on a back plate. It also includes a guide rod assembly and a through-beam photoelectric sensor. Two sets of supports are slidably mounted on the guide rod assembly. Through-beam photoelectric sensors are mounted on both sets of supports, with the sensors located at the edges of the front and rear faces of the mold box wheel, respectively. Each through-beam photoelectric sensor includes a transmitter and a receiver, which correspond to each other.

[0006] Furthermore, the circumference of the mold wheel is provided with multiple mold slots for pushing the cigarette and aluminum foil together.

[0007] Furthermore, it also includes a Beckhoff controller, with the transmitter and receiver respectively connected to the Beckhoff controller.

[0008] Furthermore, the guide rod assembly includes a screw and a guide rod body, both of which are vertically mounted on the back plate, and a bracket is connected to the screw and the guide rod body.

[0009] Furthermore, the bracket includes a threaded sleeve, a threaded sleeve outer cylinder, and a guide rod sleeve. The threaded sleeve is threadedly connected to the screw rod, and the threaded sleeve outer cylinder is sleeved on the threaded sleeve. The threaded sleeve outer cylinder and the guide rod sleeve are connected by a connecting rod, and two sensor mounting brackets are provided on the connecting rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model is equipped with a guide rod assembly and two sets of brackets slidably mounted on the guide rod assembly. Each set of brackets is equipped with a through-beam photoelectric sensor, which is located at the front and rear ends of the mold box wheel. This allows the offset of the aluminum foil at the mold box slot to be detected when the cigarette and aluminum foil are pushed into the slot together. Compared with the prior art, this detection process is carried out when the cigarette is wrapped, which makes the detection more reliable.

[0012] In this utility model, the guide rod assembly includes a guide rod body and a screw rod. The bracket includes a screw sleeve, a screw sleeve outer cylinder, and a guide rod sleeve. The screw sleeve is threaded onto the screw rod, and the screw sleeve outer cylinder is fitted onto the screw sleeve. This allows the bracket as a whole to be adjusted back and forth, thereby adjusting the two sides of the through-beam photoelectric sensor according to the aluminum foil of different widths. On the other hand, since the screw sleeve outer cylinder and the guide rod sleeve are connected by a connecting rod, the receiving end and the transmitting end always correspond during the adjustment process, thus avoiding the inconvenience and correspondence deviation caused by adjusting the receiving end and the transmitting end separately.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0019] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] refer to Figure 1-2 As shown, this utility model provides an aluminum foil offset detection device, including a mold box wheel 2, which is rotatably mounted on a back plate 1. It also includes a guide rod assembly and a through-beam photoelectric sensor. Two sets of brackets 6 are slidably mounted on the guide rod assembly. The two sets of brackets 6 are located at the front end and rear end of the mold box wheel 2, respectively. Through-beam photoelectric sensors are mounted on both sets of brackets 6, and the through-beam photoelectric sensors are located at the edges of the front end and rear end of the mold box wheel 2, respectively. The through-beam photoelectric sensor includes a transmitter 8 and a receiver 7, and the transmitter 8 and receiver 7 correspond to each other.

[0021] The circumference of the mold wheel 2 is provided with multiple mold slots 3 for pushing the cigarette stick 10 and aluminum foil paper 9 together.

[0022] In use, the cigarette is pushed laterally by the cigarette pushing mechanism, and the aluminum foil is conveyed on one side of the mold box roller 2. During the pushing process, the cigarette will press the aluminum foil into the mold box slot 3 of the mold box roller 2, thus completing the wrapping action of the cigarette. During this process, the through-beam photoelectric sensor is located on the front and rear end faces of the mold box roller 2, so that the aluminum foil pressed into the mold box slot 3 is detected on both sides. If the aluminum foil is detected on both sides at the same time, it means that there is no deviation. If the aluminum foil is not detected on one side, it means that there is a deviation.

[0023] It also includes Beckhoff controller 11, which adopts CX1030 controller. The transmitter 8 and receiver 7 are respectively connected to Beckhoff controller 11. In addition, Beckhoff controller 11 is also connected to a host industrial control computer.

[0024] Specifically, the guide rod assembly includes a screw 5 and a guide rod body 4, both of which are vertically mounted on the back plate 1, and a bracket 6 is connected to the screw 5 and the guide rod body 4. Furthermore, refer to... Figure 3 As shown, the bracket 6 includes a threaded sleeve 65, a threaded sleeve outer cylinder 61, and a guide rod sleeve 63. Preferably, the upper and lower ends of the threaded sleeve 65 are provided with hexagonal convex rings, which facilitates rotation and limits the movement of the threaded sleeve outer cylinder 61. The threaded sleeve 65 is threadedly connected to the screw 5, and the threaded sleeve outer cylinder 61 is sleeved on the threaded sleeve 65. The threaded sleeve outer cylinder 61 and the guide rod sleeve 63 are connected by a connecting rod 62. Preferably, the connecting rod 62 is U-shaped, and two sensor mounting brackets 64 are provided on the connecting rod 62. Since the threaded sleeve outer cylinder 61 and the guide rod sleeve 63 are connected by the connecting rod 62, when the threaded sleeve 65 is rotated, the threaded sleeve outer cylinder 61 and the guide rod sleeve 63 can move synchronously and cannot rotate, so that the transmitting end 8 and the receiving end 7 always correspond during the adjustment of the bracket 6.

[0025] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that those skilled in the art can devise many other modifications and implementations that fall within the scope and spirit of the principles disclosed herein. More specifically, various modifications and improvements can be made to the components or layout of the subject matter arrangement within the scope of the disclosure, drawings, and claims. Besides modifications and improvements to the components or layout, other uses will be apparent to those skilled in the art.
