Description

  The present invention relates to an adjustment leg of a gantry for adjusting the installation height of a weight sorter.

  Conventionally, a weight sorter is installed on a gantry with a weighing conveyor supported by a load cell, and a display unit is fixed on the gantry. This type of weight sorter is provided with a screw-type height adjusting device at each leg portion that supports the gantry. This height adjustment device is provided with a female threaded portion at the lower end of each leg of the gantry so that the conveying line between the weight sorter and the preceding and following conveying devices communicates without any step, and the height of each female threaded portion is adjusted. Bolts are screwed together.

  With this height adjusting device, the transport surface of the weighing conveyor can be adjusted to the height of the transport surface of the existing carry-in and carry-out conveyors. When changing the height of the weighing conveyor, each of the four height adjustment bolts can be adjusted to the desired height by rotating in the direction of extending or shortening from the lower end of each leg. .

  However, in the conventional screw-type height adjusting device, when the height adjusting bolt is extended from the lower end of the leg portion in order to increase the height of the conveying surface of the weighing conveyor, the measuring device installed as the length increases. There is a problem in that the rigidity of the conveyor is lowered, vibration is generated, and the measurement accuracy is lowered. That is, the height adjustment bolt is a substantially cylindrical screw rod having a male screw on the outer peripheral surface. If this screw rod is thickened to increase the rigidity, the weight will increase, and the external diameter of the female screw part that this height adjustment bolt will be screwed into will become bulky, and the height adjustment bolt will also be thickened. There is a limit. When the height of the weighing conveyor is changed, the height of the entire weighing device of the weight sorter including the weighing conveyor, the display unit, and the gantry is also changed, so that the display unit may be difficult to see for the operator.

  Patent Document 1 is filed by the applicant of the present application. However, when the supported body is installed at a relatively high height, the first body screw part is screwed with the supported body. An extension member is attached between the female screw portion. Thereby, it can adjust so that the 1st external thread part may be extended long from the 1st internal thread part by the part of the length of this extension member. As a result, the rigidity of the supported body to be installed can be prevented from being lowered without increasing the thickness of the first male screw portion. The height of the measuring part can be adjusted in a wide range without reducing the rigidity.

  Further, Patent Document 2 describes a part having a leg, which relates to improvement of an adjuster in which a bolt part and a nut part are combined in order to adjust the height and level used for the leg part.

  As described above, the weight sorter is an apparatus that is mainly installed in a production line and performs a weight inspection of an article conveyed from a preceding apparatus. The configuration includes, for example, a metal detection device, a feeding conveyor, a weighing conveyor, and a sorting device as shown in FIG. Articles pass from these devices through these conveyors to the weight sorter conveyor. Therefore, the horizontal line height of the conveyor of a front | former stage, the conveyor of a weight sorter, and the conveyor of a distribution apparatus needs to be the same. If the increase or decrease of the height is small, the height can be adjusted with the jack leg, but if the height adjustment range is exceeded due to a significant change in the production line, the line height is adjusted by replacing the extension member. It was. However, in the conventional height adjusting method, the height adjusting extension member and the jack leg can be screwed to the weighing unit support frame and replaced, but if the weight sorter is used for a long time, There has been a problem that the threaded portion is loosened and vibration is generated in the entire weight sorting apparatus.

  The present invention has been made to solve the above-described problems, and is a weighing unit support frame that includes a platform that supports a weighing unit of a weight sorter and a plurality of adjustment legs that support the platform. The support frame is composed of a pipe-shaped main frame, and the first loosening coupling portion made of the female screw provided on the main frame and the first loosening coupling portion made of the female screw are as described above. A female thread portion having a disk having the same diameter as the pipe diameter of the pipe-shaped main frame, a bolt through hole provided in the center of the disk, and a locking nut fixed so as to be concentric with the through hole is a female screw portion. It is a structure fixed to the lower end, and further is an adjustment leg, the adjustment leg having the same diameter as the pipe diameter of the pipe-shaped main frame, and the upper part of the adjustment leg is connected to the first loosening stop connecting part. Second series to be screwed The second connecting portion has a disk having the same diameter as the pipe diameter, a bolt through hole provided at the center of the disk, and after passing the bolt through the through hole, the disk and the bolt head are fixed to each other. The disk has a male screw, and the disk is fixed to the upper part of the adjusting leg. Further, the lower part of the adjusting leg has a female thread portion having a disk having the same diameter as the pipe diameter, a bolt through hole in the center of the disk, and a locking nut fixed so as to be concentric with the through hole. The disc has a third loosening connecting portion fixed to the lower portion of the adjusting leg, and the third connecting portion has a structure having an adjusting bolt screwed with an adjusting bolt (jack leg). Is a height adjusting device for a weight sorter.

  Conventionally, in the weight sorter lineup, if the height adjustment with the front and rear devices exceeds the adjustment range of the jack legs, the gantry is remanufactured, which increases the cost. In addition, when adjusting the height by replacing the adjusting leg, the adjusting leg may be loosened.

  According to the present invention, even if the adjustment legs are variously replaced, the first connection part of the main frame is provided with a locking connection part including a locking nut, and the first connection part provided with the locking connection part is provided with an upper part of the adjustment leg. By screwing the male screw of the second connecting portion, the first connecting portion and the second connecting portion at the top of the adjusting leg can be firmly connected. Also, since the third connecting portion at the lower end of the adjusting leg is provided with a female screw portion having a locking nut, the height adjusting jack leg that is screwed into the third connecting portion is also used for a long time. However, there is an effect that a stable measurement accuracy can be maintained since no loosening of these connecting portions occurs and unnecessary vibration is not induced.
