Description

[Detailed description of the invention] Industrial field of application This invention relates to a drum transport vehicle equipped with a measuring device that can constantly measure the total weight of held drums, the amount of released contents, the amount remaining in the cans, etc. be.

BACKGROUND TECHNOLOGY In general, a drum transporting rotary vehicle is capable of moving both vertically and horizontally relative to the drum, and has a drum holding rod equipped with a device for overturning the drum on the vertical support of the cart, and after the drum is moved to a predetermined location, the drum is removed. The contents inside the can are removed by lifting it and tipping it over. This conventional drum conveying rotary car does not know the amount taken out or the amount remaining in the can, and measures it by eye.

Therefore, in order to constantly measure the total weight of the drum and the amount of released or remaining contents, a holding rod with a drum overturning device is installed on a pair of vertical supports that make up the drum transportation rotary vehicle so that it can be moved up and down, and the weight is also detected on the vertical support. There is a rotary drum transport vehicle equipped with a weighing device that is equipped with a strain gauge type load cell, a weight indicator electrically connected to the weight detector, and a tare setting device. The weight sensor is prone to errors due to the friction of the guide rollers in the vertical columns.

Further, a drum holding rod is provided on a vertical column constituting the drum transportation rotating vehicle so as to be movable up and down, a weight detector is attached to the drum holding column, and the weight detector is electrically connected to the vertical column of the cart. There is a rotary car for transporting drums with a weighing device equipped with a weight indicator and a tare setting device (Jikkosho).
63-4080).

Problems to be Solved by the Invention This rotary vehicle for transporting drums with a weighing device picks up and overturns the drum to take out the contents, and measures the amount taken out or the remaining amount by bending the arms that grip the drum. Although this method uses a measurement method, it is not affected by the friction of the guide rollers that move the vertical support up and down, but weight detectors must be installed on both sides of the drum holding rod, and a separate sum calculator is installed for this purpose. There is a need.

Means for Solving the Problems The rotary car for transporting drums with a weighing device of this invention has a holding part for rotating the drum and discharging the contents in front of a pair of vertical supports fixed on a cart, and a drum overturning device. A holding rod is provided to be movable up and down, and the drum holding rod and a vertical support are integrally formed via a parallel link mechanism, and the parallel link mechanism is formed to be vertically movable by a guide roller of the vertical support. The lower end of the weight detector is fixed to a horizontal rod installed between them, and the upper end is suspended from an arm rod protruding from a connecting rod provided at the upper part of the rear vertical rod of the parallel link mechanism. It was made into a rotating wheel.

Operation When the drum holding rod holding the drum is lifted up, the tipping device is activated at a predetermined position, and the drum is gradually tilted to release the contents, the load applied to the drum holding rod changes. The front vertical rod of the parallel link mechanism is fixed to the drum holding rod, so as the load on the drum holding rod changes, the parallel link rotates upward and is suspended from the protruding arm at the top of the rear vertical rod. The change is detected by a weight detector, and the change is directly displayed digitally on a weight indicator, allowing you to read the emitted weight, etc.

Embodiment An embodiment of the rotary car for transporting drums with a measuring device according to the present invention will be described based on the drawings.

Fig. 1 is a front view of the rotary car for transporting drums of this invention, and Fig. 2 is a schematic view of the main parts.A pair of vertical supports 5 are provided on a trolley 1 having a frame 2 with fixed wheels 3 and rotating wheels 4. . A drum holding rod 6 has a drum holding part 7 and an overturning device 8 at its front end, and its rear end is supported by the vertical column 5 via a link mechanism 9. The link mechanism 9 includes a pair of front and rear vertical rods 10, 10a and a pair of upper and lower horizontal rods 11, 11a.
The rear vertical rod 10a is engaged with the guide rail formed by the vertical support 5 so as to be vertically movable. On the other hand, front vertical rod 10
The rear end of the drum holding rod 6 is fixed, and a weight detector 13 consisting of a strain gauge type load cell for measuring the total weight of the drum, discharge amount, etc. is installed in the center of the structure rod 12 installed on the drum holding rod 6. The lower end 13b is fixed. Further, the upper end 13a of the weight detector 13 is connected to the rear vertical rod 10a of the parallel link mechanism 9.
The drum holding rod 6 is suspended from an arm rod 15 projecting above the horizontal rod 12 of the drum holding rod 6 from a connecting rod 14 installed on the upper part of the drum.

In addition, 16 in the figure connects the rear vertical rod to the groove 5a of the vertical support 5.
A pulley is used to move the inside up and down, and 17 is a hanging rope.

Further, 18 and 19 are guide rollers, 20 is a hydraulic jack, 21 is a running handle, and 22 is a weight indicator and tare setting device that is electrically connected to the weight detector 13. The weight of the contents inside the drum can be displayed digitally. Effects of the invention The rotary car for transporting drums with a weighing device of this invention has a parallel link mechanism interposed between a drum holding rod with an overturning device and a vertical column that moves the holding rod up and down, and a weight detector of the drum contents is mounted on the holding rod. Since the lower end is provided, unlike the case where the holding rod is provided directly on the vertical support so as to be movable up and down, errors in detected values due to friction of the guide roller interposed between the holding rod and the vertical support do not occur. Further, it is not necessary to provide a weight detector for each of the drum holding rods, and there is no need for a device for summation as in the case where two weight detectors are provided.
