Description

[Detailed Description of the Invention] Field of Industrial Application This invention is applied to a container of a container conveyor such as a pivoted bucket conveyor or an apron conveyor in which both ends of the container are connected between two endless conveyor chains. The present invention relates to a drum feeder capable of loading the conveyed articles described above at an adjustable loading position.

Prior Art and Problems Therefor For example, as a conventional drum feeder for feeding a conveyed product to a pivoted bucket conveyor, Japanese Patent Laid-Open No. 61-2635 is disclosed.
There is one disclosed in Japanese Patent No. 28, which has a structure for supplying a conveyed product with a chute, and does not have a quantification function or an overcharging prevention function by itself, and adjusts the loading position of the conveyed product in a bucket. Therefore, there is a drawback that an appropriate load distribution cannot be obtained.

An object of the present invention is to eliminate the above-mentioned drawbacks of the related art and to propose a drum feeder having improved strength and reliability by adopting a drive system that supports both ends of the feeder rotating portion.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention is provided at a position for loading a product on a horizontal moving path of a container conveyor, in which both ends of the container are respectively attached to a chain of two lines, and meshes with the chain. An intermittent opening drum that is fixed concentrically to the sprocket and that has an opening formed intermittently at a pitch equal to the container mounting pitch on the peripheral surface moves opposite the opening of the container, and both ends are fixed in the rotating shaft direction in the drum. A circular trough of a conveyed object pushing screen feeder having an axial discharge opening on the lower side, and a circumferential direction of the trough discharge opening rotatably fitted to a portion other than the front end portion of the discharge opening of the trough. An outer cylinder having an adjustment opening with a variable width, and a skirt having a lower end that surrounds the flow path of the discharged conveyance from the axial opening of the trough and whose lower end opens toward the inner peripheral surface of the intermittent opening drum. The gist is the configuration of the intermittent drum feeder with the adjustable loading position.

Action The conveyed product put into the trough from the conveyed product input port is pushed by the screw and falls from the trough opening. By rotating the externally fitted outer cylinder by a desired angle and selecting the trough opening width appropriately, the axial drop distribution can be made substantially uniform. The dropped conveyed goods fall toward the inner surface of the intermittent opening drum without being scattered by the skirt, and have a substantially predetermined axial distribution in the container from the drum opening facing the container, for example, substantially uniform in the direction orthogonal to the conveyor. It is loaded so as to be distributed in the area. At the same time, the non-opening portion between the openings of the drum moves to face the connecting portion between the containers, and prevents the conveyed product from dropping onto the discontinuous connecting portion between the front and rear containers.

Embodiment FIG. 1 and FIG. 2 are an elevation view and a sectional view taken along the line II-II of an essential part of an embodiment of the present invention, respectively, in which a plurality of front and rear ends are adjacent to a chain 1 of a pivoted bucket conveyor. Both ends of the buckets V ₁ , V ₂ , ... V _{n having} a shape that does not overlap with each other are pivotably attached by pivoted pins P ₁ , P ₂ , ... P _n , and on the link plate connecting pin of the chain 1. A roller (not shown) is fitted on the roller, and
The teeth of the pair of ring-shaped sprockets 2 are meshed with each other, and the cam pins C ₁ ,
C ₂ and C _n are projected.

The left and right sprockets 2 each include a support ring 3 fixed concentrically inside each of them, and a connection ring 4 fixed inside thereof.
Intermittent opening drum 5 fixedly supported between the left and right connecting rings 4.
A pair of left and right drum support rollers 7 that are integrally coupled by and fit in the lower front and rear of the outer peripheral groove 6 of the support ring 3,
The drum 5 is rotatably supported at a fixed position by pivotally supporting a support frame 9 having both ends fixed to a fixed frame 8. Therefore, when the ring-shaped sprocket 2 meshes with the rollers on the connecting pin of the conveyor chain 2, the drum 5 rotates in synchronization with the chain 1, and the peripheral surface of the drum 5 is aligned with the upper opening of the bucket V ₁ or the like. A plurality of openings 10 are provided at equal pitches (Fig. 3).

The support cylinder 11 fixed to one side of the fixed frame 8 projects into the drum 5 from the center hole of one sprocket 2, and the end plate 12 fixed to the projecting end is attached to the end plate 14 of the skirt 13.
The bent end 17 of the circular trough 16 of the screw feeder 15 is fixed via the. The trough 16 has an end extending rearward from the center hole of the other sprocket 2 and the motor base 30.
Fixedly supported by.

A hopper 19 is provided on the inlet 18 provided at the rear of the trough 16.
And the bearings 21 on the end plate 12 and the end plate 20 fixed to the rear end of the trough 16, respectively.
The screw 22 is axially supported therein, and the sprocket 23 fixed to the outer end of the stat shaft is chain-driven to push the conveyed product supplied from the hopper 19 forward.

As shown in FIGS. 4 and 5, an axial opening 24 having a predetermined width for discharging a conveyed product is provided on the lower side of the trough 16 at an axial portion substantially facing the opening 10 of the drum 5. Further, an outer cylinder 25 is rotatably fitted on the trough 16, and an opening 24
An axial opening 26 having substantially the same width as that of is provided. However, the outer cylinder 25
Is rotatably fitted to a portion other than the front end portion of the trough 16, and the rear ends of the openings 24 and 26 substantially coincide with each other. Then, when the outer cylinder 25 is rotated to shift the opening 26 from the opening 24 by an angle θ, the central angle β of the overlapping opening portions of the openings 25 and 26 is narrowed by the angle θ from the central angle α of the opening 24. (Fig. 5).

The loose material conveyed from the hopper 19 is the screw 22.
Is pushed into the trough 16 and discharged from the overlapping opening 27 of the openings 24 and 26 and the opening 24 in front of the outer cylinder 25. The discharge amount is determined by the type of conveyed product, the width of the opening 27, the screw speed, etc. However, if the width of the opening 27 is appropriately narrowed, the conveyed product will be accumulated to some extent in the trough 16 and the outer cylinder 25 From the front end of the sheet, all the remaining conveyed articles are discharged through the wide opening 24. The rear flange 28 of the outer cylinder 25 is fixed to the flange 30 of the trough 1 by a thumb screw 29 at an appropriate angular position.

The openings 24 and 26 may have a constant width, a tapered width that widens toward the end depending on the physical properties of the conveyed object, or the opening edges may have a curved shape.

A front end plate 14 of the skirt 13 is fixedly supported by the end plate 12 in a cantilever manner.
And has a width substantially the same as that of the above, and guides the discharged conveyed product of the screw feeder 15 into the bucket V from the opening 10.

Effect of the Invention According to the present invention, since the conveyed product is forcibly pushed in the axial direction by the screw feeder, even if the length of the container such as a bucket is large, by appropriately selecting the opening width of the trough according to the kind of the conveyed product, In addition to being able to make the loading in the container substantially uniform, there is an effect that it is possible to adjust the loading amount in the container by the opening width and the screw rotation speed, prevent overloading, etc.
Further, since the front and rear parts of the screw feeder are attached to the fixing member, there is an effect that the screw feeder is excellent in strength and reliability.
