Description

Technical Field

[0001] The invention relates to the technical field of weighing equipment, in particular to a weighing device capable of automatically turning over. Background Art

[0002] Platform scales are also called floor scales. They are usually equipped with four weighing sensors and are divided into single-layer platform scales and double-layer platform scales. Platform scales without frames and supported by scale feet are called single-layer platform scales, and platform scales supported by frames (load-bearing base and its integrated frame) and rocker columns (also called support columns) are called double-layer platform scales. They are mainly composed of four main parts: load-bearing platform (scale body), force transmission mechanism, high-precision weighing sensor, and weighing display instrument, which can complete the basic weighing function of floor scales. The weighing range is generally 300Kg~15000Kg, and it is widely used in warehouses, workshops, freight yards, trade markets, construction sites and many other occasions. In weighing occasions with high precision requirements and stable performance, double-layer platform scales with frames are generally used.

[0003] In order to facilitate weighing, double-layer platform scales are usually set horizontally on the ground or on a work platform. However, some items to be weighed are in a vertical state after coming off the production line, so it is necessary to convert the items to be weighed from a vertical state to a horizontal state before they can be weighed. Since the weighing sensor of the double-layer platform scale is fixed on the scale body, and the weighing sensor is flexibly supported and connected between the support column and the base of the scale frame, when the scale body flips, swings or shakes at a large angle, the scale body will fall off the scale frame, and the weighing device will also be damaged, making it difficult to ensure normal weighing. Therefore, in the prior art, an additional flipping device is usually used to flip the items to be weighed from a vertical state to a horizontal state, and then a mechanical gripper is used to transfer the items to be weighed from the flipping platform to the platform scale for weighing. The operation efficiency is low, and the space occupied is large. In addition, during the transportation process, the mechanical gripper is easy to cause damage to the items to be weighed, thereby reducing the quality of the items and the weighing accuracy, affecting the company's reputation.

[0022] The present invention sets a guiding and limiting structure between the scale frame and the scale body. On the one hand, the cone portion of the third limiting member can play a guiding and positioning role. In the process of the platform scale flipping to a vertical position, the cone portion is gradually inserted into the positioning hole from shallow to deep until the outer peripheral surface of the cone portion is against the opening of the positioning hole, so that the center of the scale body and the scale frame are always kept in the same straight line, preventing the scale body from shaking, the center from shifting, or the scale body from rotating in the scale frame during the flipping process. After the platform scale flips back to the horizontal position, the scale body is also easier to reset. On the other hand, the cone portion also plays a pressure-bearing role, which can reduce or even avoid the pressure-bearing burden of the first limiting member, thereby improving the reliability of pressure-bearing.

[0023] The present invention provides a radial limiting structure between the scale frame and the scale body, which can limit the movement of the scale body in the radial direction and prevent the scale body from colliding with the scale frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0035] like Figure 1 , Figure 2 As shown, the present invention includes a platform scale 100, a flip platform and a display 700. The platform scale 100 is flippably arranged on the flip platform. The flip platform provides support and flipping power for the platform scale 100. The display 700 is connected to the platform scale 100 via a data transmission line 800 and is used to display the weighing value.

[0036] The flip platform includes a base 200, a flip frame 300, a flip shaft 400, a connecting rod 500 and a driving cylinder 600. The platform scale 100 is fixedly connected to the flip frame 300, and the flip frame 300 is hinged to the base 200 through the flip shaft 400; both ends of the flip shaft 400 are connected to the flip frame 300 through the second bearing assembly 300-1 and can rotate to a certain angle. The telescopic rod 600-1 of the driving cylinder 600 is connected to the flip frame 300 through the connecting rod 500, and both ends of the connecting rod 500 are connected to the flip frame 300 through the third bearing assembly 300-2 and can rotate to a certain angle; both sides of the cylinder body of the driving cylinder 600 are connected to the base 200 by the first bearing assembly 200-1, and the driving cylinder 600 can rotate to a certain angle, and drive the flip frame 300 through the connecting rod 500, and then drive the platform scale 100 to flip. The flip axis 400 is offset on one side of the telescopic rod 600-1 of the driving cylinder 600, and is offset by a certain distance relative to one side of the telescopic rod 600-1. When the telescopic rod 600-1 is extended and retracted, the flip frame 300 will flip around the flip axis 400. The connecting rod 500 has a bearing structure at both ends, which is arranged at an oblique upper part of the flip axis 400 and is offset by a certain distance outward relative to the side of the flip axis 400 facing the flipping direction, so that the driving cylinder 600 drives the flip frame 300 to flip. The driving cylinder 600 can be a hydraulic cylinder or a pneumatic cylinder. A manipulator 900 is arranged on the flip frame 300, and the manipulator 900 can be extended from the center of the platform scale 100 or retracted and hidden in the platform scale 100. There is a distance between the manipulator 900 and the platform scale 100, that is, the manipulator 900 does not contact the platform scale 100 to avoid affecting the weighing accuracy.

[0037] During actual use, the driving cylinder 600 drives the platform scale 100 to flip 90° to a vertical state through the flip frame 300, and the object to be weighed is transported to the outside of the weighing device in a vertical state. After the manipulator 900 extends from the platform scale 100 to clamp the object to be weighed, the driving cylinder 600 drives the platform scale 100 to flip 90° in the opposite direction to a horizontal state through the flip frame 300, and the manipulator 900 is retracted. The platform scale 100 directly weighs the object to be weighed, and transmits the weighing value to the display 700 through the data transmission line 800.

[0038] The platform scale 100 of the present invention is fixedly connected to the flip platform. After flipping over with the flip platform to grab the object to be weighed, it flips to a horizontal direction to directly weigh the object to be weighed, thus saving the intermediate transfer link, reducing the occupied space, improving the working efficiency, and avoiding damage to the object to be weighed during the transfer process, while ensuring the weighing accuracy.

[0039] like Figure 1 , Figure 2 As shown, the platform scale 100 is a double-layer platform scale, including a scale frame 1 and a scale body 2, the scale body 2 is arranged on the scale frame 1, and the scale frame 1 is fixedly connected to the flip frame 300. Figure 3 As shown, weighing sensors 3 are respectively arranged on the scale body 2 and in the surrounding directions thereof, and the supporting columns 31 of the weighing sensors 3 are flexibly connected to the supporting bowl of the scale frame 1. A junction box 4 is also arranged on the scale body 2, and the junction box 4 is sealed in the installation groove of the scale body 2 through a cover plate 5.

[0040] like Figure 3 As shown, the scale frame 1 includes a bottom plate 11 and an outer plate 12 perpendicular to the bottom plate 11. The bottom plate 11 is an annular plate, and the outer plate 12 is vertically arranged on the outer periphery of the bottom plate 11. A plurality of pads 13 are arranged on the bottom surface of the bottom plate 11 along the circumferential direction, and a plurality of fixing holes 14 are opened on each pad 13. The fixing holes 14 penetrate the bottom plate 11, and the scale frame 1 can be installed on the flip platform through the fixing holes 14.

[0041] The scale body 2 includes a panel 21 and an inner panel 22 perpendicular to the panel 21, and the inner panel 22 is vertically downwardly arranged on the outer side of the bottom surface of the panel 21. A plurality of beams 23 are arranged crisscrossly on the bottom surface of the panel 21 of the scale body 2 to improve the strength of the panel 21. A through opening 24 is provided in the center of the panel 21 to facilitate the manipulator 900 on the flip platform to extend from the opening 24 to grab the object to be weighed.

[0042] like Figures 4 to 8 As shown, the outer plate 12 of the scale frame 1 is sleeved on the outer side of the inner plate 22 of the scale body 2, and there is a gap between the inner wall surface of the outer plate 12 and the outer wall surface of the inner plate 22.

[0043] like Figures 3 to 5 As shown, a plurality of first connection holes 15 and a plurality of second connection holes 16 are provided on the outer plate 12 of the scale frame 1 along the circumferential direction, the first connection holes 15 are inserted with the first stopper 6, and the second connection holes 16 are inserted with the second stopper 7. Figure 3As shown, the first limiter 6 and the second limiter 7 are respectively fixedly connected to the active connection hole through the connecting member 9, and the first limiter 6 and the second limiter 7 extend radially inward toward the inner enclosure 22 of the scale body 2. When the platform scale 100 is in a horizontal state, there is a certain distance between the inner end surface of the first limiter 6 and the outer wall surface of the inner enclosure 22 to avoid affecting the weighing accuracy. The first limiter 6 constitutes a radial limit structure of the scale body 2, which can limit the movement of the scale body 2 in the radial direction to prevent the scale body 2 from hitting the scale frame 1. A first limit hole 25 is opened on the inner enclosure 22 of the scale body 2 corresponding to the second limiter 7, and the second limiter 7 is inserted into the first limit hole 25. The second limiter 7 and the first limit hole 25 are in clearance fit. When in a horizontal state, the second limiter 7 and the first limit hole 25 do not contact each other to avoid affecting the weighing accuracy. The second limiting member 7 cooperates with the first limiting hole 25 to form a jack limiting structure, which can limit the circumferential and axial movement of the scale body 2, prevent the circumferential rotation or axial movement of the scale body 2, and ensure the connection between the scale body 2 and the scale frame 1 when the platform scale 100 is hoisted as a whole or turned over with the flip platform, prevent the scale body 2 from falling off the scale frame 1, and limit the activity space of the scale body 2 within the range of the scale frame 1; when the scale body 2 is placed horizontally for weighing operations, the shaking range of the scale body 2 is limited. In this embodiment, the jack limiting structure is respectively arranged on the left and right sides and the top side of the scale frame 1 and the scale body 2.

[0044] like Figure 6 As shown, in other embodiments, the first limit member 6 and the second limit member 7 can also be inserted into the inner plate 22 of the scale body 2, and the first limit member 6 and the second limit member 7 extend outward radially toward the outer plate 12 of the scale frame 1, and the outer end surface of the first limit member 6 maintains a certain distance from the inner wall surface of the outer plate 12. A second limit hole 18 is opened on the outer plate 12 corresponding to the second limit member 7, and the second limit member 7 extends into the second limit hole 18 and fits with the second limit hole 18 with a clearance.

[0045] The first limiting member 6 and the second limiting member 7 are limiting bolts or limiting pins.

[0046] like Figure 3 , Figure 4 , Figure 7As shown, at least one fourth connection hole 26 is provided on the inner peripheral plate 22 of the scale body 2 along the circumferential direction, and a third stopper 8 is provided on the fourth connection hole 26, and the third stopper 8 extends radially outward toward the outer peripheral plate 12 of the scale frame 1. A first positioning hole 17 is provided on the outer peripheral plate 12 of the scale frame 1 corresponding to the third stopper 8, and the third stopper 8 cooperates with the first positioning hole 17 to form a guide stopper structure; when the scale body 1 is flipped to a vertical state, the third stopper 8 is inserted into the first positioning hole 17, and when the scale body 1 is in a horizontal state, the third stopper 8 does not contact the first positioning hole 17 to avoid affecting the weighing accuracy. The third stopper 8 is arranged in a direction perpendicular to the flip axis 400, and the central axis 83 of the third stopper 8 is perpendicular to the flip axis 400, so that when the platform scale 100 flips to a vertical position around the flip axis 400 with the flip platform, the third stopper 8 is convenient for guiding and positioning. In this embodiment, the guide stopper structure is arranged on the bottom side of the scale frame 1 and the scale body 2.

[0047] like Figure 7 As shown, the third limiting member 8 includes a connecting portion 81 and a tapered portion 82 . The connecting portion 81 is connected to the fourth connecting hole 26 , and one end of the tapered portion 82 extends into the first positioning hole 17 . The cone 82 is a cone with a larger inner side and a smaller outer side. The diameter of the larger end of the cone 82 is larger than the inner diameter of the first positioning hole 17, and the diameter of the smaller end is smaller than the inner diameter of the first positioning hole 17. On the one hand, the cone 82 of the third limit member 8 can play a guiding and positioning role. In the process of the platform scale 100 being flipped gradually to a vertical position, the cone 82 is gradually inserted into the first positioning hole 17 from shallow to deep until the outer peripheral surface of the cone 82 is against the opening of the first positioning hole 17, so that the center of the scale body 2 and the scale frame 1 are always kept in the same straight line, preventing the scale body 2 from shaking, the center from shifting, or the scale body 2 from rotating in the scale frame 1 during the flipping process. After the platform scale 100 is flipped back to the horizontal position, the scale body 2 is also easier to reset; on the other hand, the cone 82 also plays a pressure-bearing role, which can reduce or even avoid the pressure-bearing burden of the first limit member 6 and the second limit member 7, and improve the reliability of pressure bearing.

[0048] like Figure 8 As shown, in other embodiments, the third limit member 8 can also be inserted into the outer plate 12 of the scale frame 1, and the third limit member 8 extends radially inward toward the inner plate 22 of the scale body 2; a second positioning hole 27 is opened on the inner plate 22 of the scale body 2 corresponding to the third limit member 8, and the third limit member 8 cooperates with the second positioning hole 27 to form a guiding positioning structure.

[0049] The above description is an explanation of the present invention, not a limitation of the present invention, and the present invention may be modified in any form without violating the spirit of the present invention. The top side or bottom side refers to the relationship when flipped to a vertical position.
