Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an improvement of a bucket conveyor, and more particularly, to a kneading product manufacturing facility for manufacturing plastics, rubber, etc. It belongs to the technical field of a bucket conveyor in a kneaded product manufacturing facility equipped with a measuring device for measuring the weight of a processing material supplied to a container. 2. Description of the Related Art In a kneaded product manufacturing facility for manufacturing plastics, rubbers and the like, a bucket for transporting a kneaded primary product (hereinafter referred to as a processing material) kneaded by, for example, a pressure type kneader to the next step. A conveyor is provided. Hereinafter, a schematic configuration of such a bucket conveyor will be described.
This will be described with reference to FIG. 5 which is a schematic configuration explanatory view showing a part of a kneaded product manufacturing facility provided with a bucket conveyor. [0003] Reference numeral 51 shown in FIG. 4 denotes a pressurized kneader for kneading raw materials to produce a working material as a kneaded primary product. The working material is processed at a predetermined distance from the pressurized kneader 51. A next processing device 52 such as a roll for additional kneading, for example, is provided in the next step. A guide for guiding the bucket truck 54 having the bucket from the loading position of the processing material to the position of the next processing device 52 by a bogie moving means (not shown) between the pressurized kneader 51 and the next processing device 52. A bucket conveyor body 53 having a rail is provided. [0004] In the kneaded product manufacturing equipment having such a configuration, it is determined whether or not the whole amount of the kneaded processing material has been discharged in comparison with the weight of the raw material put into the kneading tank for automatic operation. It is necessary to measure the weight of the processing material to be supplied to the next processing apparatus 52 in advance in order to confirm whether the components are out of or within the allowable range due to leakage of the mixed raw material. [0005] Therefore, the kneaded processing material discharged from the pressurized kneader 51 is loaded on a bucket truck 54,
Thereafter, the bucket carriage 54 is pushed by a lateral moving device 55 to move the bucket cart 54 onto a weighing scale 57 which is disposed at a lower position of the bucket conveyor main body 53 and is supported by a lifting device 56 so as to be able to move up and down. Is raised to measure the total weight of the bucket truck 54 and the processing material, and then the bucket truck 54 is moved to the bucket conveyor body 53.
, And the work material is conveyed to the next processing device 52 by driving the carriage moving means. In addition, as a result of the weight measurement, when it is determined that there is a residual discharge of the processing material or that the component is out of the allowable range, an alarm is issued and the operation of the kneaded product manufacturing equipment is temporarily stopped. [0006] As described above, in the bucket conveyor according to the above-described conventional example, it is necessary to connect / disconnect the bucket truck to / from the bucket conveyor main body, and it takes a long time to measure the processing material. There is a problem to be solved that it is difficult to improve the production efficiency of kneaded products such as plastic and rubber products because it takes time and the transport efficiency is inferior. [0007] Further, the bucket conveyor according to the above-mentioned conventional example is configured to measure the total weight of the bucket truck, the bucket, and the work material as described above. Therefore, for example, if the weight of the processing material is 80 kgf, the weight of the bucket is about 100 kgf, and the weight of the bucket cart is 120 kgf.
Since it is about kgf, 80 kgf + 100 kgf = 1
It should be 80 kgf, and a weighing scale capable of measuring a maximum of about 200 kgf slightly larger than 180 kgf should be used. However, in the conventional bucket truck, the weight of the bucket truck including the bucket is about 220 kgf,
Since the total weight is 300 kgf, a weighing scale capable of measuring a maximum weight of about 350 kgf must be used, and there is a problem to be solved in that the measurement accuracy of the weight is inferior. Accordingly, an object of the present invention is to provide a bucket conveyor in a kneaded product manufacturing facility which does not require the work of connecting and disconnecting a bucket truck to and from a bucket conveyor body, and can improve the weight measurement accuracy of a work material. It is to be. [0009] The inventors of the present invention measure the weight of only the bucket and the work material when measuring the weight of the work material, and can measure the total weight of the bucket truck, the bucket, and the work material. It is possible to improve the measurement accuracy as compared with the above, and if the means for automatically fixing the bucket truck and the bucket and releasing the fixation is provided, it is possible to solve the problem according to the conventional example, The present invention has been made.
