Description

Technical Field

[0001] This utility model relates to the field of stacker crane technology, and in particular to a mechanical external dimension detection device and a stacker crane. Background Technology

[0002] With the development of modern industrial production, the technology of rail-guided stacker cranes is constantly improving and perfecting. Rail-guided stacker cranes are the most important lifting and transport equipment in automated warehouses and a hallmark of their characteristics. For some goods that require wrapping, the condition of the wrapping film cannot be guaranteed after completion. The film may sag and obstruct the photoelectric sensors used to detect whether the goods exceed size limits, leading to false alarms. Utility Model Content

[0003] The purpose of this invention is to solve the problem in the prior art where floating film wrapped around goods easily triggers photoelectric sensor alarms.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: On the one hand, a mechanical external dimension detection device is provided, including a stop bar set relative to the object to be measured; a movable plate whose one end is fixedly connected to or set close to the stop bar on the side away from the object to be measured and is movable in the direction of movement of the object to be measured; and an object sensing device located on the side of the movable plate away from the stop bar, the object sensing device being used to issue an alarm signal when it detects a change in the position of the movable plate.

[0005] Preferably, the sensing device includes a photoelectric sensor, a controller, and an alarm device. The photoelectric sensor is electrically connected to the controller and the alarm device. When the photoelectric sensor detects a sensing signal generated by a change in the position of the moving plate, it transmits the signal to the controller, and the controller controls the alarm device to issue an alarm signal.

[0006] Preferably, it also includes a bracket, on which the sensing device is mounted.

[0007] Preferably, it further includes a position adjustment device installed between the bracket and the movable plate, the position adjustment device being used to adjust the placement position of the movable plate relative to the bracket.

[0008] Preferably, the position adjustment device includes: a guide rail; a vertical adjustment plate extending and slidably mounted in a direction perpendicular to the guide rail; and a connecting component disposed between the vertical adjustment plate and the movable plate, wherein one end of the connecting component away from the vertical adjustment plate is fixedly connected to the movable plate.

[0009] Preferably, the connecting component includes: a horizontal adjustment plate mounted on the vertical adjustment plate and capable of adjusting the horizontal position, the other end of the horizontal adjustment plate being connected to the movable plate.

[0010] Preferably, the connecting assembly further includes a reset assembly disposed between the lateral adjustment plate and the movable plate. The reset assembly can approach the object sensing device under the push of the stop lever and can drive the stop lever to reset when the thrust is released.

[0011] Preferably, the reset assembly includes: a bidirectional spring hinge parallel to the length direction of the stop bar and disposed on the transverse adjustment plate; and a connecting plate fixed between the bidirectional spring hinge and the movable plate.

[0012] On the other hand, a stacker crane is also provided, including the mechanical dimensional detection device described above, which is installed on the loading platform of the stacker crane.

[0013] This utility model provides a mechanical dimensional detection device and a stacker crane, including a stop bar positioned relative to the object to be measured; a movable plate whose one end is fixedly connected to or positioned close to the stop bar on the side away from the object to be measured, and which is movable in the direction of movement of the object to be measured; and an object sensing device located on the side of the movable plate away from the stop bar, which is used to issue an alarm signal when it detects a change in the position of the movable plate. In this embodiment, by using the stop bar and the movable plate, the movable plate is used to move closer to the object sensing device instead of the object to be measured, thereby extending the distance between the object to be measured and the object sensing device. Even if there is a problem of film drift, it can avoid the film drift obstructing the object sensing device and causing false alarm signals. Furthermore, the stop bar also increases the contact area between the object to be measured and the movable plate, thereby improving detection accuracy. Attached Figure Description

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] like Figures 1-2 As shown, this utility model provides a mechanical external dimension detection device, including a stop bar 1 set relative to the object to be measured; a movable plate 2 with one end fixedly connected to or set close to the stop bar 1 away from the object to be measured and movable in the direction of movement of the object to be measured; and an object sensing device 3 located on the side of the movable plate 2 away from the stop bar 1, which is used to issue an alarm signal when it detects a change in the position of the movable plate 2.

[0019] It should be noted that the mechanical dimension detection device provided in this application is applicable to detecting whether the dimensions of an object meet the standards. Taking a stacker crane as an example, when the mechanical dimension detection device is used on a stacker crane, it can automatically detect whether the dimensions of the object meet the standards when the stacker crane is picking up or placing items (mainly for cases where the dimensions of the object are too long). It should be explained that devices that can automatically detect whether the dimensions of an object meet the standards already exist on the market. These devices mostly combine photoelectric sensors or other sensors that can perform the same function, using the sensors to sense the relative position between themselves and the object, thereby indirectly determining whether the dimensions of the object exceed the standards.

[0020] However, considering that some items will be wrapped with a thin film to provide some protection, the state of the film after wrapping cannot be guaranteed. The film may fall off its fixed position and land near the photoelectric sensor, thus blocking the sensor and causing false alarms.

[0021] To address the aforementioned technical issues, in this embodiment, the mechanical external dimension detection device mainly includes a stop bar 1, a movable plate 2, and an object sensing device 3. By using the stop bar 1 and the movable plate 2, the movable plate 2 replaces the object to be measured and approaches the object sensing device 3, thereby extending the distance between the object and the object sensing device 3. Even if there is a problem with film drift, it can prevent the film from obstructing the object sensing device 3 and causing false alarm signals. Furthermore, the stop bar 1 increases the contact area between the object and the movable plate 2, thereby improving detection accuracy.

[0022] Specifically, in the mechanical dimensional measuring device, the stop bar 1 is positioned relative to the object to be measured. The material of the stop bar 1 is preferably metal or plastic with sufficient strength and stability to ensure the accuracy of the measurement.

[0023] The movable plate 2 in the mechanical dimensional detection device can move in the direction of movement of the object to be measured. For example, when the object to be measured comes into contact with the stop bar 1, the movable plate 2 can continue to move along with the object to be measured and the stop bar 1 under the action of the stop bar 1. The movable plate 2 can be fixedly connected to the stop bar 1 or set apart from the stop bar 1, which is not limited here. When the movable plate 2 is set in a fixed connection with the stop bar 1, the movable plate 2 needs to be set on the side of the stop bar 1 away from the object to be measured, so that the movable plate 2 can replace the stop bar 1 to approach the object sensing device 3. When the movable plate 2 is set apart from the stop bar 1, the movable plate 2 must be set on the side of the stop bar 1 away from the object to be measured, and the distance between the two should not be too large to avoid the stop bar 1 not being able to contact the movable plate 2.

[0024] The object sensing device 3 in the mechanical dimensional detection device is located on the side of the moving plate 2 away from the stop lever 1. It is mainly used to issue an alarm signal when it detects a change in the position of the moving plate 2. For example, when the object to be measured is too long, it will first contact the stop lever 1 and continue to push the stop lever 1 forward until it moves the moving plate 2 close to the object sensing device 3. At this time, the object sensing device 3 detects a change in the position of the moving plate 2 and will promptly issue an alarm signal to remind the staff that the dimensional dimensions of the object to be measured do not meet the standards.

[0025] In some embodiments, the sensing end of the object sensing device 3 may be a photoelectric sensor, a proximity switch, or other devices that can perform the same function, and there is no limitation thereto. In addition, in order to realize the normal operation of the sensing device, the object sensing device 3 also includes a controller (not shown in the figure) and an alarm device (not shown in the figure). The photoelectric sensor is electrically connected to the controller and the alarm device. When the photoelectric sensor detects the sensing signal generated by the change in position of the moving plate 2, it transmits it to the controller, and the controller controls the alarm device to issue an alarm signal to remind the staff that the shape and size of the object to be measured do not meet the standard.

[0026] In one feasible implementation, the processor is an ATmega328P, a microcontroller used on the Arduino Uno board, suitable for processing analog signals and capable of reading the analog output of the sensor via an ADC (analog-to-digital converter). The alarm device is a horn or a flashing light.

[0027] In some embodiments, the mechanical dimensional detection device further includes a bracket 4, on which a sensing device is mounted.

[0028] In some embodiments, the mechanical dimensional detection device further includes a position adjustment device 5 installed between the support 4 and the movable plate 2. The position adjustment device 5 is used to adjust the placement position of the movable plate 2 relative to the support 4. The position adjustment device 5 allows for adjustment of the installation position of the movable plate 2 according to actual conditions, thereby adapting to various working scenarios.

[0029] In some embodiments, the position adjustment device 5 includes a guide rail 51; a vertical adjustment plate 52 extending and slidably mounted in a direction perpendicular to the guide rail 51; and a connecting component 53 disposed between the vertical adjustment plate 52 and the movable plate 2, with one end of the connecting component 53 away from the vertical adjustment plate 52 fixedly connected to the movable plate 2. The vertical adjustment plate 52 allows adjustment of the vertical mounting position of the movable plate 2, and it is connected to the movable plate 2 via the connecting component 53. It should be noted that, in order to allow the movable plate 2 to change its mounting position on the vertical adjustment plate 52, at least one threaded hole can be formed on the movable plate 2, and multiple threaded holes corresponding to different mounting positions can be provided on the vertical adjustment plate 52. Bolts are then passed through the threaded holes on the movable plate 2 and the vertical adjustment plate 52 and tightened to secure the movable plate 2.

[0030] In some embodiments, the connecting assembly 53 includes a lateral adjusting plate 531 mounted on the vertical adjusting plate 52 and capable of adjusting its lateral position. The other end of the lateral adjusting plate 531 is connected to the movable plate 2. The lateral adjusting plate 531 is disposed between the vertical adjusting plate 52 and the movable plate 2, and its horizontal mounting position can be adjusted. It should be noted that, in order to allow the movable plate 2 to change its mounting position on the lateral adjusting plate 531, at least one threaded hole can be formed on the movable plate 2, and multiple threaded holes corresponding to different mounting positions can be formed on the lateral adjusting plate 531. Bolts are then passed through the threaded holes on the movable plate 2 and the lateral adjusting plate 531 and tightened to secure them.

[0031] In some embodiments, the connecting assembly 53 further includes a reset assembly 532 disposed between the lateral adjustment plate 531 and the movable plate 2. The reset assembly 532 can approach the object sensing device 3 under the push of the stop lever 1, and can drive the stop lever 1 to reset when the push is released. By using the reset assembly 532, the movable plate 2 can be automatically reset when the object to be detected leaves the object sensing device 3, so as to wait for the next detection action.

[0032] In some embodiments, the reset assembly 532 includes a bidirectional spring hinge 5321 parallel to the length direction of the stop lever 1 and disposed on the transverse adjustment plate 531; and a connecting plate 5322 fixed between the bidirectional spring hinge 5321 and the movable plate 2. The bidirectional spring hinge 5321 enables the stop lever 1 to push the movable plate 2 from different angles.

[0033] Another aspect of this utility model provides a stacker crane including the mechanical external dimension detection device as described above, the mechanical external dimension detection device being installed on the loading platform of the stacker crane.

[0034] In this embodiment, when the mechanical shape and size detection device is used on a stacker crane, it can automatically detect whether the shape and size of the object to be tested meets the standard when the stacker crane is used to pick up and put down items.

[0035] This utility model provides a mechanical dimensional detection device and a stacker crane, including a stop bar 1 positioned relative to the object to be measured; a movable plate 2, one end of which is fixedly connected to or positioned close to the stop bar 1 away from the object to be measured and movable in the direction of movement of the object to be measured; and an object sensing device 3 located on the side of the movable plate 2 away from the stop bar 1, which is used to issue an alarm signal when a change in the position of the movable plate 2 is detected. This embodiment, through the placement of the stop bar 1 and the movable plate 2, utilizes the movable plate 2 to approach the object sensing device 3 instead of the object to be measured, thereby extending the distance between the object to be measured and the object sensing device 3. Even if there is a problem of film drift, it can avoid the film drift obscuring the object sensing device 3 and causing false alarm signals. Furthermore, the placement of the stop bar 1 also increases the contact area between the object to be measured and the movable plate 2, thereby improving detection accuracy.
