Description

[Detailed explanation of the idea] The present invention relates to a bifurcated chute.

A conventional bifurcated chute will be explained based on FIG. 1. 1 is the chute body, and the lower part is 2
It is bifurcated into two legs 1A and 1B. 2
is a damper in which the supporting shaft 3 at the base end is rotatably supported by a bifurcated part in the chute body 1, and is switched as appropriate to connect the upper part 1C of the chute body 1 to either one of the legs (1A or 1A). 1B]. 4 is an arm fixed to one end of the support shaft 3; 5 is a switching cylinder device for rotating the damper 2 via the arm 4;

In the above conventional structure, when raw pellets 6, for example, are thrown into the upper part 1C of the chute body 1 as shown by arrow A, the raw pellets 6 are guided by the damper 2 and guided into one leg 1A. However, since the raw pellets 6 have moisture and adhesive strength, they accumulate on the damper 2,
In the end, there was a risk of clogging the chute.

Therefore, the present invention provides a bifurcated switching chute that solves these problems, and its features include a chute main body whose lower part is bifurcated into two legs, and a bifurcated chute within the chute main body. In the switching bifurcated chute, the damper is rotatably connected to the chute body and is appropriately switched to communicate the upper part of the chute body with one of the legs. A recess is provided at the location, an extrusion plate is provided in the recess, and the extrusion plate is placed along the upper surface of the damper switched so as to open the opposing leg, toward the opened leg. According to this configuration, an extrusion means for moving is provided.
It is possible to forcibly push out sticky objects such as green pellets accumulated on the damper into either leg, eliminating the problem of the chute becoming clogged with accumulated objects as in the past. do not have.

An embodiment of the present invention will be described below with reference to FIG. 8 is a recess formed in the upper part 1C of the chute main body 1 at a location opposite to each leg 1A, 1B; 9;
10 is an extrusion plate disposed in each recess 8; the main body is supported by the upper part 1C of the chute body 1 via a support arm 11, and the tip of a piston rod passes through the upper part 1C and is connected to each extrusion plate 9; It is a pair of extrusion cylinder devices, and each extrusion plate 9 is moved along the upper surface of the damper 2, which is switched so that the extrusion plate opens the opposing leg.
Move it to the opened leg side.

In the above structure, when the green pellets 6 have accumulated to some extent on the damper 2 as shown by the solid line in FIG. 2, the piston rod of the extrusion cylinder device 10 on the right side of FIG. 2 is extended. Then, the push-out plate 9 on the right side of FIG. 2 descends obliquely over the damper 2, pushing out the green pellets 6 on the damper 2 into the open leg portion 1A. Further, when the damper 2 is switched as shown by the imaginary line in FIG. 2, and the green pellets 6 have accumulated to some extent on the damper 2, the piston rod of the extrusion cylinder device 10 on the left side of FIG. 2
The raw pellets 6 on the damper 2 are pushed out into the other leg 1B by the pushing plate 9 on the left side of the figure. The extrusion cylinder device 10 is operated by checking the accumulated amount of raw pellets 6 visually or by using a detector, or at regular intervals.

As described above, according to the switching bifurcated chute of the present invention, it is possible to forcibly push the conveyed object having adhesive force such as green pellets accumulated on the damper into one of the legs, unlike the conventional chute. The chute will not become clogged with accumulated objects. In addition, the push-out plate does not interfere with objects to be transported that are thrown into the upper part of the chute main body within the recess, and can be used effectively when the chute is clogged with objects to be transported.
