Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production, in particular to a clamping detection device for a clamping machine. Background Art

[0002] When cigarette packs are fed onto the production line, a clamping machine is required to lift the packs, separating them from the pallets and feeding them into the production line. Cigarette packs inevitably become damaged during storage. In such cases, damaged packs can be misdetected or undetected by the clamping machine's clamping detection device, causing the clamping machine to stop operating or the packs to fall off the conveyor line, making troubleshooting more difficult. Furthermore, the detection portion of the current clamping machine's clamping detection device has a small contact area with the cigarette box, and longitudinal relative movement of the packs can cause mechanical damage to the detection portion.

[0003] The current solution is to add a sensor to the clamping machine's clamp cylinder to detect changes in compressed air pressure. If the sensor remains unchanged, the clamp is considered in place and the next step can be carried out. However, adding a pressure sensor to the clamp cylinder makes it difficult to control the clamping force in actual production, and if it fails, it is difficult to replace.

[0004] In view of the above problems, the inventors of the present invention finally obtained the present invention after a long period of research and practice. Utility Model Content

[0005] In order to solve at least one aspect of the above technical problems, the present invention provides a clamping detection device for a clamping machine, which reduces the erroneous influence of damaged cigarette packs on the clamping device of the clamping machine and improves the smoothness of equipment operation.

[0006] The technical solution adopted by the utility model is:

[0007] Provided is a clamping detection device for a clamping machine, comprising an outer sleeve and a movable inner body, wherein the movable inner body is sleeved within the outer sleeve and is capable of sliding along the inner cavity of the outer sleeve; a metal sheet is mounted on the movable inner body, and a proximity sensor is mounted on the outer sleeve; the front end surface of the movable inner body serves as a detection contact surface;

[0008] During the process of clamping the cigarette pack by the clamping machine, the detection contact surface contacts the cigarette pack, so that the movable inner body is squeezed by the cigarette pack and slides along the inner cavity of the outer sleeve. When reaching the predetermined position, the metal sheet blocks the proximity sensor.

[0009] Furthermore, the clamping detection device of the clamping machine further includes a limit baffle, a guide column and a spring, wherein the limit baffle is fixed in the inner cavity of the outer sleeve body, and a guide hole is provided on the limit baffle; one end of the guide column is fixed to the movable inner body, and the other end passes through the guide hole; the spring is sleeved on the guide column and is located between the movable inner body and the limit baffle;

[0010] When the movable inner body is squeezed by the cigarette pack and slides, the spring is compressed.

[0011] Furthermore, there are two guide posts and two springs, and each guide post is fitted with a spring.

[0012] Furthermore, the clamping detection device of the clamping machine also includes a sliding wheel, which is installed on the movable inner body; the movable inner body slides along the inner cavity of the outer sleeve body through the sliding wheel.

[0013] Furthermore, the clamping machine clamping detection device also includes a clamping machine controller, and the proximity sensor is communicatively connected to the clamping machine controller.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This new clamping detection device for clamping machines can detect various depths without requiring on-site adjustment of the test pressure, offering greater flexibility than methods that incorporate pressure change sensors within cylinders. The material is readily available and affordable, reducing replacement costs. It also offers strong resistance to longitudinal impacts, and its structure and dimensions can be modified to suit specific circumstances, providing strong adaptability.

[0018] The above and other technical features and advantages of the present invention are described in more detail below with reference to the accompanying drawings.

[0019] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation to the present invention.

[0020] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0021] Cigarette bales are combined and entered into the system via a clamping machine and pallet, then stored in a high-bay warehouse. During production, the system delivers the required bales to the production line, and the clamping machine separates the pallets from the bales. If the clamping machine frequently issues alarms due to damaged bales, this malfunction can disrupt smooth production and increase the operator's workload. If damaged bales are mistakenly detected and fall during handling, troubleshooting time and personnel requirements increase, impacting the silk-making workshop's material feeding and production.

[0022] like Figure 1 As shown, the clamping detection device for the clamping machine comprises an outer sleeve 2 and a movable inner body 1. The movable inner body 1 is mounted within the outer sleeve 2 and can slide along the inner cavity of the outer sleeve 2. A metal sheet 7 is mounted on the movable inner body 1, and a proximity sensor 6 is mounted on the outer sleeve 2. The front surface of the movable inner body 1 serves as a detection contact surface 9. When the clamping detection device for the clamping machine is installed on the clamping machine, a cigarette pack enters the clamping machine, and the clamping machine clamps actuate to clamp the cigarette pack. The cigarette pack contacts the detection contact surface 9 of the clamping detection device, generating a compressive force that causes the movable inner body 1 to move backward along the inner cavity of the outer sleeve 2. The backward-moving movable inner body 1 and the metal sheet 7 move synchronously. When the metal sheet 7 blocks the proximity sensor 6, they reach a predetermined position, triggering the proximity sensor. The detection contact surface 9 has a large contact area with the cigarette pack, providing strong longitudinal impact resistance. The clamping force can be adjusted via the clamping detection device.

[0023] In some embodiments, the clamping detection device of the clamping machine also includes a limit baffle 4, a guide column 5 and a spring 3. The limit baffle 4 is fixed in the inner cavity of the outer sleeve body 2, and a guide hole is provided on the limit baffle 4. One end of the guide column 5 is fixed on the movable inner body 1, and the other end passes through the guide hole. The spring 3 is mounted on the guide column 5 and is located between the movable inner body 1 and the limit baffle 4. During the sliding process of the movable inner body 1 due to the squeezing of the cigarette pack, the spring 3 is compressed. The movable inner body 1 and the metal sheet 7 that move backward move synchronously, and the movable inner body 1 is acted upon by the spring 3 between the limit baffle 4 and the movable inner body 1.

[0024] Preferably, there are two guide posts 5 and two springs 3, each with a spring 3 mounted on it. The limit baffle 4 is arranged parallel to the detection contact surface 9. One end of the two guide posts 5 abuts the detection contact surface 9, and the other end passes through the guide hole in the limit baffle 4. The spring 3 is limited between the limit baffle 4 and the detection contact surface 9.

[0025] In some embodiments, the clamping detection device further includes a sliding wheel 8 mounted on the bottom of the movable inner body 1. The movable inner body 1 slides along the inner cavity of the outer sleeve 2 via the sliding wheel 8. The provision of the sliding wheel 8 ensures smooth sliding between the movable inner body 1 and the outer sleeve 2, preventing jamming and enhancing reliability.

[0026] The proximity sensor 6 is in communication with the clamping machine controller. The working process of the clamping machine equipped with the clamping machine clamping detection device is as follows:

[0027] 1. The cigarette pack enters the clamping machine, and the clamping machine moves to tighten the cigarette pack;

[0028] 2. The cigarette pack contacts the detection contact surface of the tightening detection device, generating an extrusion force that causes the detection contact surface (the movable inner body 1) to move backward along the two guide posts 5 within the outer sleeve body 2;

[0029] 3. The detection contact surface 9 and the metal sheet 7 move backward at the same time. The detection contact surface 9 is acted upon by the spring 3 between the limit baffle 4 and the detection contact surface 9. At the same time, the metal sheet 7 blocks the proximity sensor 6, triggering the proximity sensor to output a signal.

[0030] 4. After receiving the signal, the clamp rises and moves forward to transport the cigarette pack;

[0031] 5. After the clamping machine has carried the cigarette pack to its place, the clamp is released and the detection contact surface 9 is acted upon by the spring 3 between the limit baffle 4 and the detection contact surface 9, rebounding to a quasi-working state.

[0032] 6. After the tightening detection device returns to the quasi-working state, the fixture returns to the quasi-working state and waits for the next clamping task. The work flow of the tightening detection device is completed.

[0033] The above are only preferred embodiments of the present invention and are intended to be illustrative rather than restrictive. The structures and connection methods of the components of the present invention are subject to change, and any equivalent transformations and improvements based on the technical solution of the present invention should not be excluded from the scope of protection of the present invention.
