Description

[Detailed explanation of the idea] Industrial applications Concerning a platform scale that uses both a weight and a graduated rod.

Conventional technology In conventional weight-type measuring instruments, the object to be measured is hung on the shorter end of the fulcrum from a fulcrum that is offset to the horizontal end of the rod, and a hook for the weight is attached to the longer end of the fulcrum to determine the light weight of the object. In addition, a horizontally movable weight with a scale that has a scale on the longer arm between the fulcrum and the end of the fulcrum is installed to accommodate the fulcrum. A weight-type measuring instrument that can handle a variety of weights by taking advantage of the fact that the transmission force of the weight increases smoothly as the distance between the weights increases.

Problems that the invention aims to solve: Conventional weight-type measuring instruments predict the approximate weight of the object to be measured every time the weight of the object changes, select a weight that is equivalent to this, and then keep the weight level. There is a drawback that moving and adjusting the weight requires manual time and skill. This was devised to eliminate this drawback.

Means for Solving the Problems The present invention will be explained with reference to FIG. 1. The spiral shape 1 has gear-shaped teeth on the outer periphery of the spiral shape whose surface is spirally wound only once. and 2
are arranged vertically on the left and right, and the position of the outer circumferential surface of the longest radius of the husband and the position of the outer circumferential surface of the shortest radius of the husband are opposed to each other and mesh. Further, the shaft 3 is inserted through the center of the spiral mold 1 on one side and fixed at a predetermined position. A saucer 7 is installed on the upper end of the tooth holder 6 provided in the holder. Further, a continuous weight device 10 (registered as a utility model) is installed at a desired position on the outer periphery of a wheel 8 which is installed and fixed at a desired position on one side of the shaft 4 which is inserted through the center of the spiral mold 2 on the other side and fixed at a desired position. An automatic device for a weight-type measuring device in which the upper end of the filament body 9 is fixed (pending application).

Operation To measure the weight of an object with the configuration described above,
When an object within the measurable range is placed on the tray 7, the tray 7 and tooth rod 6 are lowered depending on the weight, and the gear 5, shaft 3, and spiral mold 1 are rotated, and the mesh of the spiral mold 2 is adjusted. The positions of the objects will change together. At that time, the spiral mold 1 sequentially moves from the position of the shortest radius of engagement to the direction of the longer radius, and the force transmitting the weight of the object to be measured is strong at first and gradually changes smoothly to a weaker direction.
Furthermore, as the spiral type 2 moves sequentially from the longest radius position to the shortest radius, the shaft 4 and wheel 8 are rotated, and continuous weights are generated depending on the degree of winding of the wire body. As the number of weights to be lifted increases sequentially, the force that transmits the weight of the weight is weak at first and gradually increases smoothly due to the action of the spiral type 2, and then transfers to the weight of various types and becomes the force transmitted by the weight of the object to be measured. , automatically responds to reach equality and automatically weighs.

Embodiment 1 of the embodiments other than those described above will be explained with reference to FIG. With respect to the position of the outer circumferential surface of the radius of One end of the filament body 9 is fixed and wound once in the direction of increasing radius, and the other end is fixed to the outer peripheral surface of the opposite spiral mold 2 at the shortest radius, and A gear 5 is provided and fixed at a predetermined position on one side of a shaft 3 which is provided through the center of the shaft and fixed at a predetermined position.
A saucer 7 is installed at the upper end of a tooth rod 6 which is provided in a vertical shape and meshes with the teeth at a desired position. Furthermore, a continuous weight device 10 (utility model registration pending) is installed at a desired position on the outer circumferential surface of a wheel 5, which is installed and fixed at a desired position on one of the shafts 4 which penetrates through the center of the spiral mold 2 and is fixed at a desired position.
An automatic device for a weight-type measuring device in which the upper end of the filament body 9 is fixed.

Embodiment 2 of the embodiments other than those described above will be explained with reference to FIG. The position of the outer circumferential surface of the longest radius is placed on the upper side with the position of the outer circumferential surface of the shortest radius facing the husband, and the boundary between the position of the longest radius and the position of the shortest radius is placed on the left and right sides of each other. A flexible filament 9 fixed to the outer circumferential surface of the shortest radius of the spiral mold 1 provided on the opposite side is wound once in a direction in which the radius becomes longer, and a saucer 7 is attached to the hanging tip. Hang it. Further, at the position of the outer peripheral surface of the spiral mold 2 at the shortest radius, the upper end of a flexible filament body 9 is fixed, in which the required number of weights of arbitrary shape are connected at the required positions.

Furthermore, an automatic device for a weight-type measuring instrument in which one shaft 3 is connected to the center of the spiral molds 1 and 2 and fixed at a desired position of the husband.

Also, if you place something to be measured on the saucer, the degree of rotation of the shaft will differ depending on the weight, so a pointer is provided at the required location on the shaft and a scale plate is provided around the back of the pointer, so that the weight can be indicated with the pointer.

Effects As mentioned above, conventional weight-type measuring instruments are manually operated, which requires skill and effort, but by using a spiral type, the spiral type automatically rotates by simply placing the object to be measured on the tray. In order to smoothly transfer and transmit both the transmission force of the weight of the object to be measured and the transmission force of the weight of the weight to be lifted, and to automatically and quickly transfer the weight of the object to be measured and the weight of the weight to be lifted, we have developed technology. This has the effect of reducing the time required for measurement by eliminating manual operations.
