９はカウンタウエイト、１０はダンパーである。 Conventionally, the above-mentioned dividing machine has been of the type shown in FIG. In the figure, 1 is a roller conveyor, the center of which is supported by a fulcrum. 2 is its fulcrum. When the bail rubber 3 is conveyed on this roller conveyor 1, the center of gravity of the bail rubber 3 is at the fulcrum 2.
The roller conveyor 1 tilts until it reaches the top. This inclination is detected by a differential transformer 4 provided at one end of the roller conveyor 1, and its detection output is amplified by an amplifier 5 and supplied to a control section 6. The control unit 6 controls the servo motor 7, which is the drive source of the roller conveyor 1, so as to correct the inclination of the roller conveyor 1. When the center of gravity of the bail rubber 3 reaches the fulcrum 2, the roller conveyor 1 stops. At this time, a cutting machine 8 provided so as to sandwich the roller conveyor 1 and face the fulcrum 2 cuts the bail rubber 3 into two.
9 is a counterweight, and 10 is a damper.

ず、例えば１：３や２：３のような比率にベール
ゴムを分割することもできなかつた。 In this two-splitting machine, the roller conveyor 1 is the fulcrum 2.
Moreover, since the bail rubber 3 is heavy, it is unstable, and as a balance, the roller conveyor 1 must move slowly until it is balanced, resulting in poor responsiveness.
Therefore, the bail rubber 3 stops only after its center of gravity passes through the fulcrum 2, resulting in poor cutting accuracy. Moreover, this bisecting machine could only divide the bale rubber into two equal parts, and could not divide the bale rubber into ratios such as 1:3 or 2:3.

よつて所定の比率にベールゴムを切断できる。 This invention was made to solve the above two problems. Two conveyors are provided on a common platform, and weighing devices for both conveyors are provided below the platform. Both conveyors are configured to stop when the outputs become equal. This improves responsiveness and cutting accuracy. Furthermore, the bail rubber can be cut to a predetermined ratio by multiplying the outputs of both measuring devices by respective predetermined coefficients and cutting the bail rubber when the outputs of the multiplied values become equal.

ードセル５６を切断できる。 Next, the reason why it is possible to divide into a:b by the above calculation will be explained. It is now assumed that a dividing plane that divides the bail rubber 56 into parts a and b is located on the vertical center line 13 shown in FIG. The distance between this dividing plane and the center of gravity △l
is expressed as Δl=l/2-b/a+bl=a-b/2(a+b)l. At this time, the output of the load cell 38
Due to the moment, there is a relationship between W A and the output W B of the load cell 40 as follows: W A (L/2-△l) = W B (L/2+ △ l). The added value is always the weight W of the veil rubber. Therefore, W A and W B are as follows: W A =W (L/2+△l)/L W B =W (L/2-△l)/L. Substituting △l=a-b/2(a+b)l into both equations and rearranging them, W A and W B become W A = W(L+a-b/a+bl)/2L W B = W(L- a-b/a+bl)/2L. Therefore, the output W A of the load cell 38 is multiplied by (L-a-b/a+bl)/2L, and the output W B of the load cell 40 is multiplied by (L+a-b/a+bl)/2L, and both multiplied values are equal. At this time, the dividing plane for dividing into a:b is located on the vertical center line 13 where the cutting machine 50 is located. Therefore, by changing the ratios a and b, the load cell 56 can be cut at any ratio.
