Description

Weighing device
The present invention relates to a weighing device, in particular a weighing device that comprises a platform on which a load to be weighed has to be placed and a series of load transducers, the so-called load cells, placed below the platform in a preset configuration.
When this type of weighing device is used to weigh loads of large dimensions, such as, for example vehicles, transporting the device from the place of manufacture to the place of installation is generally difficult owing to the dimensions of the loading platform, which, frequently, is wider than the loading plane of normal freight vehicles.
This requires special vehicles to be used, with a significant increase in transport costs, or requires the loading platform to be arranged tilted on the transport plane of the vehicle. This implies complicated locking operations of the platform on the transporting plane of the vehicle, in order to be able to perform transporting in safe conditions. These operations affect the cost of transport and entail significant loss of time in operations of loading and unloading the weighing device onto the vehicle that is intended to transport it.
An object of the present invention is to provide a weighing device that is easily transportable and installable, in particular when it is of large dimensions.
The object of the invention is achieved with a weighing device according to claim 1.
The weighing device according to the invention can be easily transported also when the transverse dimensions thereof exceed the transverse dimensions of the freight vehicle used. Further, the weighing device according to the invention can be calibrated in the place of manufacture and can be installed in the place of use without the need to check calibrating of the weighing device. A non-limiting embodiment of the invention is illustrated in the description that follows, with reference to the attached drawings, in which:
Figure 1 is a perspective view of a weighing device according to the invention;
Figures 2 and 3 are perspective views that illustrate how the weighing device according to the invention is placed in transport condition;
Figure 4 is a frontal view of the device in Figure 1;
Figure 5 is an enlarged detail of Figure 4;
Figure 6 is an enlarged detail of Figure 3;
Figure 7 is an enlarged detail of Figure 1;
Figure 8 is a top view of a detail of the device in Figure 1. With reference to the figures, a weighing device 1 according to the invention comprises a platform 2 intended for receiving the loads to be weighed, associated with a supporting frame 3.
The platform 2 is divided into a first part 2a and into a second part 2b. Also the supporting frame 3 is divided in a first part 3a of frame, with which the first part 2a of the platform 2 is associated, and into a second part 3b of frame with which the second part 2b of the platform 2 is associated. In an operating position, the first part 2a and the second part 2b of the platform 2 are simply rested, respectively, on the first part 3a of the supporting frame 3 and on the second part 3b of the supporting frame 3.
When it is necessary to transport or move the weighing device 1, the first part 2a and the second part 2b of the platform 2 are connected respectively to the first part 3a and to the second part 3b of the frame 3, as will be disclosed below.
The first part 3a of frame and the second part 3b of frame 3 are connected to a pair of hinges 4 , in such a manner as to rotate with respect to one another around an axis A that is substantially parallel to the platform 2.
Respective load cells 5, intended for detecting the weight of a load placed on the platform 2, are associated with the first part 2a of the platform 2 and with the second part 2b of the platform 2.
In the embodiment illustrated, with the first part 2a and with the second part 2b two respective load cells 5 are associated that are arranged on opposite ends of the respective part 2a, 2b of the platform 2. In all cases it is possible to associate with each part 2a, 2b of the platform 2 a number of load cells 5 greater than two.
Each load cell 5 is mounted between a base plate 6, fixed to the frame 3, and an upper plate 7 fixed to the respective part 2a, 2b of the platform 2.
Fixing the first part 2a and the second part 2b of the platform 2 to the first part 3a and to the second part 3b of the frame 3, respectively, also prevents, during transport or movement operations, of the weighing device 1 according to the invention, the load cells 5 possibly undergoing movements due to movements of the platform 2 compared with the frame 3, said movements being able, for example, to cause a misalignment of the load cells 5 with respect to the respective base plates 6 and upper plates 7 that would influence the results of the weighing measurements.
In order to fix the first and the second part 2a and 2b of the platform 2 to the respective first part 3a and second part 3b of the frame 3, in this manner preventing a misalignment of the load cells 5, for each load cell 5, there is a pair of locking elements 8, 9 (Figure 5), for example in the form of brackets, arranged on opposite sides with respect to the load cell 5, fixed below- the base plate 6 and fixable to respective shelves 15 and 16 fixed below the respective part 2a, or 2b, of the platform 2. Fixing occurs via first fixing means 17 and 18, associated with the shelves 15 and 16, for example screw or bolt means, that is insertible into respective slits 10 made in each bracket 8, 9.
Each load cell 5 is further associated with a quick-fit connecting element 11 that enables the load cell to be connected electrically to a junction box, which is not shown. to which all the electrical connections of the various load cells 5 are connected.
This enables in the phase of constructing the weighing device 1 the electrical connections between the load cells 5 and the junction box to be set up without being necessary to make the electrical connections during installation, with the risk of connecting one or more cells in an incorrect position.
In the weighing device according to the invention, to connect the load cells 5 to the junction box, it is sufficient to connect to each load cell 5 the respective connecting element 11, associated with the load cell 5 and already connected in a correct position to the junction box.
The first part 3a and the second part 3b of the supporting frame 3 are connected to the hinges 4 by a respective first connecting plate 12a and a respective second connecting plate 12b that, when the weighing device 1 is in an operating condition, face and are in contact with one another.
The connecting plates 12a e 12b are provided with first holes 13 into which the dowels (which are not shown) are insertible to ensure correct alignment of the connecting plates 12a and 12b when the weighing device 1 is placed in the operating condition.
Further, the connecting plates 12a and 12b are provided with further holes 14 intended for receiving second fixing means, for example bolts, for fixing together the connecting plates 12a and 12b and thus the first frame 3a and the second frame 3b.
When the weighing device 1 according to the invention has to be transported, to take the weighing device 1 to the place of use, after it has been assembled in the place of production or to move the weighing device 1 from one place of use to another place of use, the load cells 5 are first locked, inserting the first fixing means into the slits 10 of the brackets 8, 9. The second fixing means is then removed that fixes together the first frame 3a and the second frame 3b, and the dowels inserted into the first holes 13 of the connecting plates 12a and 12b, thus completely release the first frame 3a from the second frame 3b. At this point it is possible to rotate the first frame 3a and the second frame with respect to one another 3b, as shown in Figure 2, until they overlap, in the folded configuration illustrated in Figure 3.
In this folded configuration, the width of the overall dimensions of the weighing device 1 according to the invention is halved, so it is easy to load the weighing device on a freight vehicle of conventional type, arranging the weighing device 1 horizontally on the loading plane of the vehicle. Owing to the possibility of folding the first part 3a and the second part 3b of the frame 3 on one another, it is not necessary to arrange the weighing device 1 in a tilted position on the loading plane of the freight vehicle, or resort to special freight vehicles of greater width than normal freight vehicles .
Further, in order to install the weighing device 1 in the place of use, it is sufficient to rotate again the first part 3a and the second part 3b of the frame 3 until the first part 3a and the second part 3b of the frame 3 are taken to the configuration of Figure 1, to fix the first part 3a and the second part 3b of the frame 3 together by inserting the dowels and the further fixing elements into the holes 13 and 14 of the connecting plates 12a and 12b, to release the load cells 5 by removing the fixing elements from the brackets 9 and connect the quick-fit connecting elements 11 to the respective load cells 5 to make the electrical connections between the load cells 5 and the junction box.
As the load cells 5 have been locked mechanically during transport, so as not to be able to become misaligned with respect to the base plate 6 and to the upper plate 7, and the electrical connections to the junction box are set up in such a manner that each load cell 5 is connected, by the connecting elements 11, to a set inlet of the junction box, without the possibility of error, it is not necessary to check the calibration of the weighing device 1 carried out during the manufacture phase, inasmuch as events cannot occur, such as, for example, misalignment of the load cells 5 or incorrect connection of the load cells 5 to the junction box that may alter calibration performed during assembly phase. This makes mounting of the weighing device 1 in the place of use extremely easy and reliable and noticeably reduces mounting and operating time of the weighing device 1 according to the invention.
In Figure 8 there is shown a top view of a detail of the weighing device 1 according to the invention, to illustrate in which manner, when the weighing device is in an operating condition, longitudinal and laterals movements of the first part 2a and of the second part 2b of the platform 2 are prevented when a vehicle is placed on the platform 2 to be weighed, or is removed from the platform 2 after being weighed.
When the weighing device 1 is in an operating condition, with each end of the first part 2a and of the second part 2b of the platform 2 respective access ramps 21 are associated, that are fixable to the frame 3, the function of which, in addition to facilitating the placing and removal of a vehicle on and from the platform 2, is to prevent longitudinal and transverse movements of the first part 2a and of the second part 2b of the platform 2, caused by said vehicle. For this purpose, with each end of the first part 2a and of the second part 2b of the platform 2 a stop element 19 is provided that is fixed to a supporting element 20 connected to the respective part 2a, 2b of the platform 2. Each stop element 19 is intended to come into contact with the respective access ramp 21 to stop the longitudinal movements of the first part 2a and of the second part 2b of the platform 2. Further, each ramp 21 is provided with a further stop element 22 intended for coming into contact with a respective supporting element 20 to stop the transverse movements of the respective first part 2a, or second part 2b of the platform 2.
