Background

In the field of colored and ferrous metal strip lines, the steel coil scale is mainly used for weighing coiled materials of the strip lines in the metallurgical industry on line. Generally, the sensor is installed below the base of the scale, 2 scale frames are erected on the base, and two sides of the upper part of each scale frame are made into saddles with inclined planes or circular arc-shaped openings. The provision of an open saddle facilitates movement of the transport apparatus therein and placement of the coil when weighed.

The above conventional practice generally has the following problems: most of steel coil scale saddles can only be suitable for placing in normal size (diameter), and cannot be suitable for placing and weighing when excess materials are coiled in a small manner. Because the size of the opening of the saddle of the scale is 40-60 mm larger than the width of the saddle on the conveying equipment, the saddle of the conveying equipment can conveniently move up and down, so that a small coil is difficult to weigh and store, an off-line weighing station needs to be added, and the efficiency is reduced.

Conventional steel coil saddles typically suffer from the following problems:

firstly, the storage saddle is only a storage saddle, and the storage saddle needs to be manually placed when in use;

secondly, the coiling lifting of the saddle of the conveying equipment is influenced after the saddle is placed, and the saddle can be directly taken away by other equipment only at the station;

and thirdly, in order to restore the storage of the coils with other specifications after use, the coils must be removed, and the safety and the efficiency are influenced.

Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

Further, although the terms used in the present invention are selected from publicly known and used terms, some of the terms mentioned in the description of the present invention may be selected by the applicant at his or her discretion, the detailed meanings of which are described in relevant parts of the description herein.

Furthermore, it is required that the present invention is understood, not simply by the actual terms used but by the meaning of each term lying within.

As shown in fig. 1 to 6, fig. 1 shows the working position and the opening size of the adaptive device in normal weighing (weighing a large roll). Fig. 2 shows the installation positions and the mutual relationship of the adaptive blocks. Fig. 3 shows a state where the adaptive block is just in contact with the steel coil when the small coil is weighed. Fig. 4 shows the state of the adaptive block when weighing a small coil and the state when finally weighing a steel coil. Fig. 5 shows the state when the coil is just contacted when the coil is taken out by the lifting saddle of the coil moving trolley after the weighing of the small coil is finished, and fig. 5 and fig. 6 show that the self-adaptive device automatically resets, and the change of the opening of the self-adaptive device does not influence the action of the lifting saddle of the coil moving trolley. Fig. 6 shows the highest coiling position state of the lifting saddle of the coil moving trolley after the weighing of the small coil is finished, and fig. 6 and 5 show that the self-adaptive device automatically resets, and the change of the opening of the self-adaptive device does not influence the action of the lifting saddle of the coil moving trolley.

As shown in figures 1 to 6, the saddle mechanism capable of adapting to the opening comprises a fixed saddle 10, at least one pair of adaptive blocks 20, a rotating shaft 30 and a restorer 40, wherein the fixed saddle 10 is provided with an opening 11, each adaptive block 20 is arranged at two side parts of the opening 11 through the rotating shaft 30, and the adaptive block 20 is driven to rotate around the rotating shaft 30 downwards by the self weight of an object 50 to be weighed, so that the size of the opening 11 is changed. One end of each restorer 40 is fixed on the fixed saddle 10, the other end is connected to the adaptive block 20, and the adaptive block 20 is driven to restore to the initial state.

Preferably, the upper end surfaces of both side portions of the opening 11 are provided with slope surfaces 12, and the adaptive block 20 is mounted on the slope surfaces 12. One end of the adaptive block 20 is provided with a connecting portion 21 extending outward, the connecting portion 21 is rotatably connected to a corresponding side portion of the opening 11 by a rotating shaft 30, and the other end of the adaptive block 20 is connected to a repositioner 40.

Further, the upper end face of the adaptation block 20 is preferably a plane. The adaptive mass 20 is preferably an elongated block structure.

Here, the angle range in which the adaptive block 20 is rotated with respect to the slope surface 12 is preferably 0 to 60 degrees.

According to the structural description, the saddle mechanism with the self-adaptive opening adopts the self-adaptive block 20 connected with the fixed saddle 10 through the rotating shaft 30 (the self-adaptive block 20 and the fixed saddle 10 are provided with corresponding holes which can pass through the rotating shaft 30), and the self-adaptive block and the fixed saddle are driven to rotate around the rotating shaft through the self-weight of the steel coil, so that the opening of the saddle is changed. The return action of the adaptive mass 20 after rotation (i.e. return to the initial state) is actuated by a return device 40 (spring or other mechanism) fixed at one end to the fixed saddle 10 and connected at one end to the adaptive mass 20.

The structure is mainly characterized in that an unpowered rotatable part is added on the fixed saddle 10, and the self rotation angle can be automatically adjusted according to the diameter of the material to be borne so as to fit and change the opening width of the saddle.

A rotatable self-adapting block 20 is arranged on the upper surface of the fixed saddle 10 of the scale frame near the center end of the scale. When the diameter of the coiled material is small to a certain value, the small coil drives the self-adaptive block to rotate, so that the opening size of the saddle of the scale frame on two sides is reduced automatically, namely the diameter B of the opening 11 is adjusted to the diameter B of the opening 11 automatically, and the phenomenon that the saddle falls down due to the fact that the small coil cannot resist the gravity due to the deformation resistance in the diameter direction is avoided. After weighing is completed, the lifting saddle of the conveying mechanism takes away the coiled material, and the self-adaptive block 20 is driven by the restorer 40 to be in a normal state.

As shown in fig. 7, fig. 7 shows the relationship between the position of the adaptive device and the size of the opening between a large roll and a small roll. The present invention also provides a coil balance 100 that includes an adaptively openable saddle mechanism as described above.

Preferably, the coil balance 100 further includes a scale frame 110, a scale base 120 and a sensor 130, wherein the scale frame 110 is mounted on the scale base 120, the sensor 130 is mounted on the bottom of the scale base 120, and the fixed saddle 10 is mounted on the upper end of the scale frame 110.

When the user uses the device, the conveying trolley is provided with a conveying machine lifting saddle 200, and the conveying trolley moves on a track arranged in a space enclosed by the scale seat 120 and the scale frame 110, is not in contact with the components forming the space and has enough safety distance. The conveyor lifting saddle 200 moves up and down in the direction of the opening 11 for placing or removing the object to be weighed 50. The object 50 to be weighed may preferably comprise rolls of various diameter sizes.

For example, according to the above description, a specific scenario for practical application of the coil scale of the present invention is as follows:

for example, the application scene is steel coil weighing, the steel coil scale is installed in the middle of a strip rolling line, and a saddle of the scale is used for storing steel coils during weighing and can conveniently enable conveying equipment to do lifting action in the middle. The size (diameter) of coil of strip has big or small, needs to go up the balance to weigh as the material of less coil of strip footpath, installs the self-adaptation saddle body that is close to central tip on balance frame upper portion and can change the rotational position along with the diameter size of coil of strip for the opening of saddle is by big to little change, holds that the coiled material can be reliable and safe deposit, accomplishes the action of weighing.

The conveying trolley takes the coiled material off the reel of the coiling machine, the coiled material is moved to the center of the steel coil scale after rising, the lifting saddle of the conveying trolley descends to enable the coiled material to slowly fall onto the saddle of the scale frame for weighing, and weight signals are displayed through the display instrument. After the upper computer acquires the weight information, the lifting saddle of the conveyor slowly rises to support and separate the coiled material from the scale frame saddle, so that the scale platform displays weight and moves to the next station after returning to zero.

When the coil contacts the adaptive block on the saddle of the scale stand, if the contact point is on the side of the pivot axis away from the center of the scale, it remains in the original state. If the contact point is near the center of the scale, the self-adapting blocks rotate inwards respectively by the gravity of the coiled material and by taking the self-rotating shaft as the center, so that the opening of the saddle is correspondingly reduced, and the coiled material is supported.

After weighing, the conveying equipment saddle rises to hold the coiled material and rise to separate from the saddle, and in the process, the self-adaptive block is restored to the normal position under the pulling of the restorer, so that the stable working state can be kept for a long time.

In summary, the saddle mechanism with adaptive opening and the coil balance comprising the saddle mechanism can effectively bear materials with smaller coil diameter than that of a common small coil, thereby solving the problem existing in the prior product/technology that the size of the opening of the saddle needs to be additionally changed manually.

The self-adaptive opening saddle mechanism does not influence the metering precision, does not influence the lifting action of the saddle of the conveying mechanism, and is safer. The method has better self-adaptive capacity and can not increase the workload of use and maintenance.
