The packet missing detection device of the independent strip external packing machine shown in fig. 1 is arranged at the strip cigarette transportation platform and is used for detecting whether packet missing exists in the passing strip cigarettes. The device comprises a door bracket 1, a first switch group 2 and a second switch group 3. In general, the packets of cigarettes in a cigarette are stacked in 10 boxes of upper and lower layers. The first switch group 2 is arranged above the cigarette carton transportation platform and is used for detecting whether the upper cigarette packet is in short of the packet, and the second switch group 3 is arranged in an interlayer below the cigarette carton transportation platform and is used for detecting whether the lower cigarette packet is in short of the packet. The door type bracket 1 is fixedly arranged on the cigarette carton transportation platform through wing plates extending from two sides. Specifically, the wing plate is in threaded connection with the guardrail of the cigarette transporting platform. The span of the door type bracket 1 is matched with the width direction of the cigarette carton conveying platform.

The door type bracket 1 is used for arranging the first switch group 2 above the strip cigarette conveying platform to detect the strip cigarettes on the strip cigarette conveying platform. As shown in fig. 2, the door type bracket 1 is provided with a plurality of single-row mounting holes 5, the arrangement direction of which is perpendicular to the conveying direction of the cigarette carton conveying platform. The mounting holes 5 are used for mounting the first switch group 2. The mounting hole 5 can be arranged in a clamping connection with the first switch group 2 in a form fit manner. The detection end of the first switch group 2 can penetrate out of the mounting hole 5 and align with the cigarette conveying platform. Since the number of single-layer packets to be detected in the present application is 5, the number of the mounting holes 5 and the switches in the first switch group 2 is set to 5 here. The arrangement distance between the adjacent mounting holes 5 can be equal or unequal, and only the fact that each switch can detect the corresponding cigarette packet in the upper cigarette packet is required, namely the arrangement distance between the adjacent mounting holes 5 is smaller than the width of the 2-time cigarette packet. Preferably, the mounting holes 5 are equally spaced here, with a spacing of a single packet width. The method and the device can detect whether all cigarette packages in the single-layer cigarette package exist or not at one time when the cigarettes pass through, and the detection process is rapid and convenient.

The second switch set 2 may be disposed in reference to the first switch set 1, which is not described herein again. The first switch set 1 may select a non-fully shielded inductive switch and the second switch set 2 may select a fully shielded inductive switch. The selection basis is that the fully-shielded inductive switch is suitable for an environment in which a metal object exists in a certain range in the radial direction of the detection head, and the non-fully-shielded inductive switch is suitable for an environment in which no metal object exists in a certain distance in the radial direction of the detection head. In this application, strip cigarette transport platform top has sufficient space and does not have the metal object, selects non-full shielding type inductive switch, and strip cigarette transport platform below owing to strip cigarette transport platform's existence, has separated strip cigarette transport platform when detecting, so can select full shielding type inductive switch.

As shown in fig. 3, the device further comprises a protective case 4. The protection box 4 is sleeved on the door type support 1 and is used for protecting the first switch group 2 on the door type support 1. The protection box 4 is a box body structure with a top cover only, and a preformed hole 6 matched with the mounting hole 5 is arranged on the top cover of the protection box 4. The reserved hole 6 is used for allowing the first switch group 2 to pass through when the protection box 4 is sleeved on the door type bracket 1. The circumference of the bottom end of the protection box 4 is provided with a convex connecting plate for connecting the protection box 4 to the door type bracket 1. The connection plate and the protection box 4 are integrally formed. The connecting plate is connected with the portal frame 1 through a thread structure.

Referring to fig. 4, the first switch group 2 and the second switch group 3 are electrically connected to a controller 7. The controller 7 is configured to receive the detection signals of the first switch group 2 and the second switch group 3 and perform a result process of whether there is a packet missing. In the packet missing detection in the application, 2 input points are needed, 2 output points are needed, and the proximity switch selects PNP with high-frequency output, so that the group selects an integral programmable controller with high-frequency input. The integrated programmable controller is typically selectable by control function or input-output point count. The integrated PLC has fixed I/O points, low price and small user selection space, and is used for a small control system. The controller 7 is further electrically connected with the alarm 8, and is configured to control the alarm 8 to send out an alarm in an acousto-optic-electric or other manner after the packet missing signal transmitted by the first switch group 2 or the second switch group 3 is acquired, so as to remind an operator to select and maintain the corresponding cigarette.

The strip cigarette is finished when entering the strip cigarette conveying platform, the strip cigarette on the plane runs stably, intermittent motion is performed under the action of the pushing arm, intermittent detection can be performed by using the pause of the cigarette packet, and the installation and detection have the advantages of stability, compactness and convenience in construction. The posture of the cigarette is generally that the length direction is perpendicular to the transport direction, but it may occasionally occur that the cigarette moves on the cigarette transport platform in such a manner that the length direction is parallel to the transport direction, in which case the first switch group 2 and the second switch group 3 arranged in the perpendicular transport direction cannot accurately detect whether the cigarette lacks the pack, and therefore, the present application is provided with the verification assembly 10 in front of the cigarette transport platform close to the door bracket 1. The validation assembly 10 includes a single row of photosensitive elements 11 arranged in a vertical transport direction. The arrangement length of the photosensitive member is matched with the length setting of the cigarette. The photosensitive member 11 is communicatively connected to the controller 7. When only part of the photosensitive members 11 detect that the cigarettes pass (for example, the cigarettes pass in the transport direction parallel to the length direction), the transport posture of the cigarettes at this time is judged to be wrong, and the reject processing is performed on the corresponding cigarettes.

The strip cigarette conveying platform is provided with a rejecting component 20 along the rear of the door type support in the conveying direction, and the rejecting component 20 is used for rejecting the strip cigarettes with wrong conveying posture and correct conveying posture but with the problem of pack missing from the strip cigarette conveying platform. Specifically, the reject assembly 20 includes at least two first push plates 21 and second push plates 22 disposed adjacent one another. The two pushing plates are used for removing cigarettes which are wrong in transportation posture and correct in transportation posture but have the problem of pack shortage. The lengths of the first push plate 21 and the second push plate 22 are respectively matched with the length and the width of the cigarettes so as to push out the corresponding cigarettes. The first push plate 21 and the second push plate 22 are connected to a first hydraulic rod 23 and a second hydraulic rod 24, respectively. The two hydraulic levers are driven by a hydraulic pump. The cigarette conveying platform is provided with a removing opening 25 for removing cigarettes in the moving direction matched with the first pushing plate 21 and the second pushing plate 22. The hydraulic pump is electrically connected to the controller 7. The hydraulic pump withdraws the matched cigarette carton after receiving the pushing signal of the controller 7.

If fig. 5 is a table for checking the detection effect of the missing packet after the device in the application is put into use, no false detection or missing detection occurs in the detection process of multiple cigarettes, and the practicability is extremely strong.
