Abstract
Description
Technical Field
[0001] The present application relates to the technical field of logistics package size measurement, and in particular to a package pressing device in a logistics package size measurement device. Background Art
[0002] In the international logistics industry, for small parcels (such as letters, small pieces of clothing), the charges are usually not based directly on their length, width and height, but on the fixed size of the parcel storage box they can be stuffed into. For example, see Figure 6 , there are 7 storage boxes of different sizes from left to right. Different sizes of storage boxes represent different freight rates. For example, the freight rate charged for a package stuffed into storage box B1 is usually lower than the freight rate charged for a package stuffed into storage box B7. In order to facilitate stuffing, the small package usually needs to be pressed before stuffing. The following example illustrates a measurement method in the prior art. Figure 7 , workers need to manually stuff the package into a rectangular hole of fixed size. Figure 7 The cost is X yuan (e.g. 8 yuan). If the Figure 7 The rectangular hole on the left, see if it can be inserted Figure 7 If it is possible to fit the rectangular hole K2 on the right (larger than the hole on the left), the cost will be Y yuan (usually larger than X, such as 15 yuan). This manual measurement method not only has the problem of low efficiency, but also has the problem of easily crushing the package. Utility Model Content
[0003] In view of the above problems, the purpose of the present application is to provide a package pressing device in a logistics package size measuring device to solve the above problems.
[0004] In order to achieve the above-mentioned purpose, the present application adopts the following technical solution: a package pressing device in a logistics package size measuring device, the package pressing device includes a driving mechanism, a pulling member and a pressure plate, one end of the pulling member is fixedly connected to the movable member on the driving mechanism, and the other end of the pulling member is fixedly connected to the pressure plate, the pulling member is used to provide pulling force to the pressure plate, and the pressure plate is used to press the package.
[0005] Furthermore, the pulling member is soft and slender, and is a combination of one or more of a rope, a chain, a belt, a thread, and a silk.
[0006] Furthermore, when the measurement starts, the driving mechanism drives the movable member to move in the first direction, and the pressing plate descends to press the package.
[0007] Furthermore, after the measurement is completed, the driving mechanism drives the movable member to move in a second direction, and the pressing plate rises, and the second direction is opposite to the first direction.
[0008] Furthermore, a distance measuring sensor is arranged above the pressing plate to detect the distance between the pressing plate and the distance measuring sensor, and the height of the package can be calculated based on the distance.
[0009] Furthermore, the pressure wrapping device also includes a first mounting plate, a second mounting plate, an optical axis and a bearing, the two ends of the optical axis are respectively fixed on the first mounting plate and the second mounting plate, the bearing can slide relative to the optical axis, and the pressure plate is fixedly connected to the bearing.
[0010] Furthermore, the first mounting plate, the second mounting plate, and the pressing plate are arranged parallel to each other and perpendicular to the optical axis.
[0011] Furthermore, the driving mechanism is mounted on the first mounting plate, the distance measuring sensor is mounted on the bottom of the first mounting plate, and the pressing plate is located between the first mounting plate and the second mounting plate.
[0012] Beneficial effects: See Figure 3 and Figure 4 When the height of the package needs to be measured, the driving mechanism drives the slider to move in the first direction (to the right), so that the rope is lowered, and then the pressure plate is lowered to achieve the purpose of pressing the package. Since the rope does not exert downward pressure on the pressure plate, but only provides upward traction, when the rope is loose, the pressure plate will no longer press down, and the maximum pressure applied to the package will never exceed the gravity of the pressure plate itself, so it can be ensured that the package will not be crushed. The distance between the pressure plate and the distance sensor can be obtained by the distance measuring sensor, so that the height of the package can be calculated. The solution provided by the present application also greatly improves efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.
[0021] In view of the problems existing in the prior art, the present application provides a package pressing device in a logistics package size measuring device to solve the problem, which is described in detail below with reference to the accompanying drawings. The height of the package measured in the present application refers to: the height of the package after being pressed (also called thickness).
[0022] See also Figure 1 The size measuring device includes a package pressing device 100, a conveying module 200, and a light curtain measuring module 300. The package pressing device 100 is used to press the package and measure the height of the package after being pressed. The conveying module 200 includes a conveyor belt 201. The conveying module 200 is used to carry and convey the package. The light curtain measuring module 300 is used to measure the length and width of the package.
[0023] See also Figure 2The package pressing device 100 includes a driving mechanism 110, a pulling member 120, and a pressing plate 130. The pulling member 120 is soft and slender, and only provides traction (tension) to the pressing plate 130 without applying pressure; the pulling member 120 is preferably a rope (hereinafter, the rope is used as an example for description), of course, the rope can also be replaced by a chain, a belt, a line, a silk or other similar slender objects that provide tension. One end of the rope is fixedly connected to a movable member 111 on the driving mechanism 110, and the movable member 111 is used to drive the rope fixed thereon to move, and the movable member 111 is preferably a slider (hereinafter, the slider is used as an example for description); the other end of the rope is fixedly connected to the pressing plate 130, so that the rope can provide tension to the pressing plate 130; the pressing plate 130 is used to press the package, and the pressing plate 130 is usually set in a rectangular shape to facilitate pressing all the packages. Preferably, the portion of the rope close to the slider is in a horizontal state, and the portion of the rope close to the pressure plate 130 is in a vertical state, thereby converting the horizontal force into the vertical force, thereby achieving the purpose of pulling the pressure plate 130 to rise and fall.
[0024] Further, see Figure 3 and Figure 4 A distance sensor 140 is disposed above the pressure plate 130 to detect the distance between the pressure plate 130 and the distance sensor 140, and the height of the package can be calculated based on the distance. When measuring the height of the package, the driving mechanism 110 drives the slider to move in the first direction (in Figure 3 and Figure 4 The rope is lowered, and the pressure plate 130 moves downward under the action of gravity to press the package. The speed of the slider movement can be controlled by the driving mechanism 110, and then the speed of lowering the pressure plate 130 can be adjusted. This will not cause too much impact on the package, so the package will not be crushed. In addition, since the rope will not exert downward pressure on the pressure plate 130, the rope can only provide upward traction to the pressure plate 130. Therefore, the maximum pressure on the package will not exceed the gravity of the pressure plate 130 itself. Even if the driving mechanism 110 or the entire measuring device suddenly fails or loses power, the package will not be crushed. After the measurement is completed, the driving mechanism 110 drives the slider to move in the second direction (in Figure 3 and Figure 4 The second direction is opposite to the first direction. At this time, the rope is retracted, driving the pressure plate 130 to move upward to wait for the next time to press the package. The following example illustrates how the application measures the height of the package after being pressed: the distance between the distance sensor 140 and the conveyor belt 201 on which the package is placed is fixed, so the distance is known and is recorded as H1; after the measurement starts, the drive mechanism 110 is controlled to move in the first direction to press the package, and the distance between the pressure plate 130 and the distance sensor 140 at this time is obtained, which is recorded as H2. The height of the package can be calculated by the difference between H1 and H2.
[0025] Further, see Figure 2 The pressure wrapping device 100 further includes a plurality of pulleys 150, and the middle section of the rope is wound around the pulleys 150 to facilitate the transmission of force and change the direction of the force.
[0026] Further, see Figure 5 The pressure wrapping device 100 further includes a first mounting plate 160, a second mounting plate 170, an optical axis 180, and a bearing 190. The first mounting plate 160 and the second mounting plate 170 are fixedly connected through the optical axis 180, the first mounting plate 160 is located above the second mounting plate 170, and the pressing plate 130 is located between the first mounting plate 160 and the second mounting plate 170. For the sake of convenience and to save the space occupied by the pressure wrapping device 100 as a whole, it is preferred that the driving mechanism 110 is arranged on the first mounting plate 160. Of course, in other embodiments, the driving mechanism 110 can also be arranged separately on one side of the first mounting plate 160. The driving mechanism 110 and the plurality of pulleys 150 are all fixedly mounted on the first mounting plate 160, preferably fixed on the top of the first mounting plate 160. The distance sensor 140 is installed at the bottom of the first mounting plate 160 to detect how far the pressing plate 130 is from it. A through hole is provided in the bearing 190, and the optical axis 180 passes through the through hole. The bearing 190 can slide up and down relative to the optical axis 180. The two ends of the optical axis 180 are respectively fixed on the first mounting plate 160 and the second mounting plate 170. The other end of the rope is fixedly connected to the bearing 190, specifically, it can be fixedly connected by a connecting piece. Similarly, the pressing plate 130 is also fixedly connected to the bearing 190, specifically, it can be fixedly connected by another connecting piece, so that the purpose of fixing the other end of the rope to the pressing plate 130 is achieved. The pressing plate 130 is located above the conveyor belt 201, and the second mounting plate 170 is located below the conveyor belt 201. The light curtain measurement module 300 is fixed above the conveyor belt 201, preferably fixed on the first mounting plate 160, so that the space occupied by the pressure wrapping device 100 as a whole can be saved. Preferably, there are 2-4 optical axes 180 and bearings 190, and more preferably four. The two ends of the four optical axes are respectively arranged at the four corners of the first mounting plate 160 and the second mounting plate 170. The bearings 190 can move in the vertical direction relative to the corresponding optical axes 180, thereby providing vertical guidance for the movement of the pressure plate 130 to avoid lateral movement, so that the pressure plate 130 moves more smoothly.
[0027] Furthermore, the first mounting plate 160, the second mounting plate 170, and the pressing plate 130 are arranged parallel to each other and are perpendicular to the optical axis 180. The optical axis 180 and the bearing 190 are preferably linear optical axes and linear bearings, so that the pressing plate 130 can move in the vertical direction under the guidance of the linear optical axis and the linear bearing, so that the pressing plate 130 can be stable when rising or falling, and the entire pressing plate 130 is horizontal and will not tilt, so that the distance between the distance sensor 140 and the pressing plate 130 is more accurate, and the height of the package finally calculated is also more accurate. The material of the pressing plate 130 is preferably tempered glass, because tempered glass has the advantages of being relatively flat, cheap, and strong. When pressing the package, the pressing plate 130 can remain stable and flat without tilting, and can also compact the package, so that the distance between the distance sensor 140 and the pressing plate 130 is reasonable and relatively accurate, and the height of the package finally calculated is also relatively accurate; of course, the material of the pressing plate 130 can also be wood or steel.
[0028] Preferably, see Figure 2 The pressure wrapping device 100 includes at least two ropes, which are respectively denoted as the first rope 121 and the second rope 122. The pressure wrapping device 100 also includes three pulleys, which are respectively denoted as the first pulley 151, the second pulley 152, and the third pulley 153. Among them, one end of the first rope 121 is fixed on the slider, and the first rope 121 passes through the first pulley 151. The first mounting plate 160 is also provided with a plurality of through holes, so that the other end of the rope can pass through and be fixedly connected with the pressure plate 130. Under the action of the first pulley 151, the tension of the first rope 121 changes from the horizontal direction to the vertical direction; the second rope 122 needs to pass through two pulleys: the second pulley 152 and the third pulley 153. One end of the second rope 122 is fixed on the slider, and the second rope 122 passes through the second pulley. The first pulley 152 and the third pulley 153 are placed perpendicular to each other, that is, the central axes of the two pulleys are vertical, the second pulley 152 and the third pulley 153 are arranged on both sides of the slider, that is, the slider is arranged between the second pulley 152 and the third pulley 153. The purpose of this is to achieve the purpose of making the ropes rise or fall uniformly when the slider moves in a certain direction, so that the pressing plate 130 can be driven to move smoothly in the vertical direction without tilting. More preferably, the pressure wrapping device 100 includes four ropes and six pulleys, wherein two ropes and three pulleys form a group, and the winding and placement of each group is basically similar to the above-described method, so that four ropes provide tension to the pressing plate 130, so that the pressing plate 130 can move more smoothly. It should be noted that, according to the understanding of those skilled in the art, the meaning of the ropes passing around the pulleys mentioned here specifically means that the ropes are wrapped around the pulleys, not away from the pulleys.
[0029] Further, the driving mechanism 110 is a screw slider linear motion mechanism, and of course, it can also be other linear motion mechanisms in the prior art.Preferably, the rope can be an industrial rope or a steel rope, etc., to enhance its strength and service life when used.
