[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Although the description of this utility model will be presented in conjunction with preferred embodiments, this does not mean that the features of this utility model are limited to this embodiment. On the contrary, the purpose of describing the utility model in conjunction with the embodiments is to cover other options or modifications that may be derived based on the claims of this utility model. To provide a deep understanding of this utility model, many specific details will be included in the following description. This utility model may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of this utility model, some specific details will be omitted in the description. It should be noted that, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0028] It should be noted that in the present specification, similar reference numbers and letters represent similar items in the following drawings, and therefore, once an item is defined in one drawing, it need not be further defined and explained in subsequent drawings.

[0029] The terms "first", "second", and the like are used only to distinguish descriptions, and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present embodiment, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set", "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present embodiment can be understood according to the specific circumstances.

[0031] At present, in actual production, after the inner frame paper completes the loose rolling process, it will run towards the inner frame paper cutting device located at the downstream station to cut the inner frame paper. Because the conveying path of the inner frame paper is relatively long, the inner frame paper is prone to skew during the conveying process, resulting in unqualified cutting of the inner frame paper, thereby causing low product qualification rate.

[0032] To solve the above technical problems, the utility model provides a kind of detection device, whether the skew of inner frame paper can be detected quickly, to remove the skew of inner frame paper in time, avoid the problem of the decrease of product qualification rate due to the unqualified cutting of inner frame paper.

[0033] To make the technical scheme and advantages of the utility model more clear, the implementation of the utility model is further described in detail below.

[0034] Reference Figure 1 The implementation of the utility model provides a kind of detection device, including installation support 1 and detection mechanism, detection mechanism is located on installation support 1, detection mechanism includes two detection units 2, two detection units 2 are respectively located at the two sides of inner frame paper 6 along the width direction of inner frame paper 6, the spacing of the detection end of two detection units 2 along the width direction of inner frame paper 6 is less than or equal to the width of inner frame paper 6, and detection unit 2 can detect whether there is inner frame paper 6 in its detection area.

[0035] When it is needed to detect whether inner frame paper 6 is skewed during conveying, the detection device provided by the present application is arranged on the conveying path of inner frame paper 6, so that two detection units 2 are respectively located at the two sides of inner frame paper 6, for example, Figure 1As shown in the figure, the distance between the detection ends of the two detection units 2 along the width direction of the inner frame paper 6 is less than or equal to the width of the inner frame paper 6. If the inner frame paper 6 is not skewed, both of the two detection units 2 can detect the inner frame paper 6 in their detection areas. If at least one of the detection units 2 detects that there is no inner frame paper 6 in its detection area, it means that the inner frame paper 6 is skewed along its width direction. At this time, the skewed inner frame paper 6 can be manually or automatically rejected to avoid the problem of product qualification rate reduction caused by unqualified cutting of the inner frame paper 6.

[0036] In order to enable those skilled in the art to better understand the specific structure of the detection mechanism and the mounting bracket, the embodiments of the detection mechanism and the mounting bracket are further described in detail below through several examples.

[0037] Example 1

[0038] Reference Figure 1 and Figure 2 The mounting bracket 1 includes an upper bracket 11 and a lower bracket 12 which are arranged at intervals along a direction perpendicular to the inner frame paper 6, such as the Y1 direction shown in the figure. Figure 1 The detection unit 2 is a transmissive optical fiber sensor 3 which includes a transmitting optical fiber sensor 31 and a receiving optical fiber sensor 32. The transmitting optical fiber sensor 31 and the receiving optical fiber sensor 32 are respectively arranged on the upper bracket 11 and the lower bracket 12, and the positions of the transmitting optical fiber sensor 31 and the receiving optical fiber sensor 32 in the same detection unit 2 correspond to each other, and the transmitting optical fiber sensor 31 can emit a signal towards the receiving optical fiber sensor 32. If the inner frame paper 6 is not skewed, the signal emitted by the transmitting optical fiber sensor 31 in the detection unit 2 will be blocked by the inner frame paper 6 between the transmitting optical fiber sensor 31 and the receiving optical fiber sensor 32, and the corresponding receiving optical fiber sensor 32 will not be able to receive the signal. If the signal emitted by the transmitting optical fiber sensor 31 in any one transmissive optical fiber sensor 3 is received by the corresponding receiving optical fiber sensor 32, it means that the inner frame paper 6 is skewed along its width direction at this time.

[0039] Example 2

[0040] Reference Figure 3 The mounting bracket 1 includes a mounting rod 13 which is located above the inner frame paper 6, and the detection unit 2 is arranged on the mounting rod 13. Specifically, the detection unit 2 is a laser sensor 4 which includes a transmitting part and a receiving part. The transmitting part can emit a signal along a direction perpendicular to the inner frame paper 6, such as the Y1 direction shown in the figure. Figure 3The laser sensor 4 is configured to emit a laser beam 41 along the Y2 direction (as shown in the figure). The Y2 direction can be a vertical direction. A reflection plate 7 is arranged below the inner frame paper 6. The reflection plate 7 is configured to reflect the laser beam 41 back to the laser sensor 4 along the Y2 direction. The receiving part of the laser sensor 4 is configured to receive the reflected laser beam 41. If the inner frame paper 6 is not skewed, the inner frame paper 6 will block the laser beam 41 emitted by the laser sensor 4 from reaching the reflection plate 7, i.e., the laser beam 41 will hit the surface of the inner frame paper 6. Since the surface of the inner frame paper 6 is rough, the laser beam 41 hitting the inner frame paper 6 will only be diffusely reflected and cannot be reflected back to the receiving part of the laser sensor 4 along the Y2 direction. When the receiving part of any one of the laser sensors 4 receives the laser beam 41 emitted by the corresponding emitting part, i.e., the laser beam 41 emitted by the laser sensor 4 can reach the reflection plate 7 without being blocked by the inner frame paper 6, it indicates that the inner frame paper 6 is skewed at this time.

[0041] The above embodiments are further detailed descriptions of the detection mechanism and the mounting bracket, and the specific implementation of the detection mechanism and the mounting bracket is not limited to the above descriptions. Any equivalent implementation or modification without departing from the scope of the present application should be included in the scope of the patent.

[0042] The embodiment of the present application also provides a packaging machine comprising the detection device of any one of the above.

[0043] Optionally, the packaging machine further comprises a cutting mechanism (not shown in the figure) and a rejection mechanism (not shown in the figure). The cutting mechanism is arranged downstream of the detection device along the conveying direction of the inner frame paper and is configured to cut the inner frame paper. The rejection mechanism is arranged downstream of the cutting mechanism along the conveying direction of the inner frame paper 6 and is configured to reject the inner frame paper 6. When the detection device detects that the inner frame paper 6 is skewed, the rejection mechanism can reject the skewed inner frame paper 6. The rejection mechanism comprises a rejection rod, a paper receiving box and a driving cylinder. The rejection rod is movable between a first position and a second position. When the rejection rod is located at the first position and the inner frame paper 6 runs to the rejection rod, the rejection rod can reject the inner frame paper 6. The paper receiving box is arranged below the rejection rod and the inner frame paper 6 rejected by the rejection rod can fall into the paper receiving box. The driving cylinder is connected to the rejection rod and is configured to drive the rejection rod to move between the first position and the second position.

[0044] Optionally, the packaging machine further comprises a control unit (not shown in the figure), which is electrically connected with the output end of the detection unit 2 and the driving cylinder respectively. The control unit is used for marking the inner frame paper at the detection unit as a skew inner frame paper when any one of the detection units 2 detects that there is no inner frame paper 6 in the detection area, and controlling the driving cylinder downstream of the detection unit 2 to start when the skew inner frame paper runs to the rejection mechanism, and the driving cylinder drives the rejection rod to move to the first position. Specifically, the control unit comprises a timing module, which is used for starting timing when the control unit receives the signal sent by the detection unit 2. Since the inner frame paper 6 runs at a constant speed, and the cutting mechanism cuts the inner frame paper at a certain time. Therefore, the time for the inner frame paper 6 to run from the detection unit 2 to the rejection mechanism is a fixed time T. When any one of the detection units 2 detects that there is no inner frame paper 6 in the detection area, and the timing module calculates the time to reach T, it means that the skew inner frame paper detected by the detection unit 2 has run to the rejection mechanism at this time. At this time, the control unit controls the driving cylinder to start, and drives the rejection rod to move to the first position to reject the skew inner frame paper 6, thereby improving the product qualification rate.

Those skilled in the art can make various changes in form and details, including making a number of simple deductions or substitutions, without departing from the spirit and scope of the present application.
