Description

  The present invention relates to a chute damper device for a dispenser, and in particular, is provided at a chute opening of a dispenser disposed at the bottom of a storage tank that stores loose articles, and the stored rose articles are disposed below. The present invention relates to a chute damper device for accurately dropping onto the center of a belt conveyor.

  In the facility for storing loose objects such as wood chips, the storage is moved to the center side of the bottom of the storage tank 10 by the rotation of the screw conveyor 24 rotating along the bottom of the storage tank 10 of the storage tank 1 as shown in FIG. Usually, a dispenser 2B is provided which is dropped onto the belt conveyor 30 of the conveying device 3 disposed below by a cylindrical chute 20b through a dispensing hole 12 opened in the center.

  In such a dispenser 2B, a skirt 21 is provided so as to cover the range from the chute 20b opening to the lower belt conveyor 30 periphery, so that the discharged roses are not scattered around the belt conveyor 30. However, if the item to be dispensed is a relatively large piece, the amount of the item to be dispensed is likely to fluctuate. It is difficult to ensure an accurate conveyance amount.

  In response to such problems, a plate-like chute damper that abuts while the discharged rose falls is suspended from the chute opening of the dispenser, so that even if the dispensed amount fluctuates and the drop position fluctuates, A chute damper device is proposed in Japanese Utility Model Laid-Open No. 6-56031, etc., in which a loose article delivered to the center of a belt conveyor is guided.

  In this way, by placing a plate-like chute damper that rectifies the flow of the discharged material at the chute opening, the falling direction of the discharged rose material can be easily aligned with the center of the belt conveyor. However, when a loose product such as a wood chip having a relatively large size and a non-uniform shape / size is a dispensed item, the dispensed amount is likely to fluctuate easily and more easily shift. It becomes difficult for the single chute damper alone to stably drop the belt conveyor to the center of the belt conveyor.

Japanese Utility Model Publication No. 6-56031

  The present invention is intended to solve the above-described problems. When a stored loose article is dispensed onto a lower belt conveyor by a dispenser, the dispensed article is accurately handled in accordance with various situations. And it makes it a subject to be able to drop in the center of a belt conveyor stably.

  Therefore, the present invention is such that a rose object dispensed by a plate-like chute damper suspended from a chute opening that guides a loose article dispensed on the belt conveyor below the dispenser falls so as to be placed on the center of the belt conveyor. In the chute damper device that rectifies the direction, the chute damper is eccentrically arranged in the advancing direction of the discharged material on the upstream side from the chute center line, and the chute damper has an inner surface on the inner side surface on the lower end side of the chute. It curves so that it may follow, and it guides so that fall of the paid-out rose thing may be settled in the predetermined range from the extension of the center line.

  In this manner, the center line of the chute is prevented so that the falling direction does not spread excessively by forming the bowl-like shape by curving with the shock absorbing surface on which the falling object comes into contact (collision) falling inside the chute damper. It becomes easy to align the roses that are paid out while guiding them near the center of the belt conveyor.

  Further, in this case, if an angle adjusting means is provided which is connected to the upper end side of the chute damper and the hanging angle can be changed within a predetermined range, the size / shape and amount of the discharged rose In accordance with the situation, it is possible to adjust the angle so that the roses from which the chute damper is delivered easily align with the center of the belt conveyor.

  Further, in this case, the chute damper is divided into two left and right parts and arranged in parallel, and each has an angle adjusting means, and the two chute dampers can be individually adjusted in angle. If this is the case, rectification of the dispensed items can be performed more precisely.

  Furthermore, if the chute damper device of the above-mentioned dispenser is for a dispenser disposed in a storage tank that stores wood chips as loose objects, the shape and size are uneven and difficult to align in the center of the belt conveyor. The rectification function is particularly effective in the delivery of wood chips.

  According to the present invention, which has a chute damper that guides the discharged rose falling the chute so that it falls within a predetermined range from the extended line of the chute center line on the curved surface, the discharged rose corresponding to various situations can be obtained. It can be accurately and stably dropped onto the center of the belt conveyor.

It is a longitudinal cross-sectional view of the storage tank provided with the chute damper apparatus of the dispenser which is embodiment in this invention. (A) is the expanded partial longitudinal cross-sectional view which shows the detail of the chute damper apparatus of FIG. 1, (B) is sectional drawing which follows the XX line of (A). It is a perspective view for demonstrating operation | movement of the chute damper apparatus of FIG. It is a longitudinal cross-sectional view of the storage tank provided with the chute damper apparatus of the dispensing machine by a prior art example.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 is a vertical cross-sectional view showing a state in which a dispenser 2A provided with a chute damper device 20A of the present embodiment is disposed at the bottom of the storage tank 1. In the present embodiment, it is assumed that the storage tank 1 stores a wood chip which is a loose article having a non-uniform unit shape and size.

  In the storage tank 10 for storing such loose materials, a screw conveyor 24 that rotates along the bottom surface is disposed on the bottom side thereof, and the storage material is collected in the central payout hole 12 by the rotation of the shaft, and below that. It is dropped on the belt conveyor 30 of the arranged conveying device 3 and is paid out.

  Further, the dispenser 2A guides the discharged roses collected in the payout hole 12 directly above the belt conveyor 30 with a cylindrical chute 20a. The fallen roses are scattered around the belt conveyor 30. A skirt 21 is provided so as not to be present. The above configuration is the same as that of the conventional dispenser 2B described in FIG.

  The dispenser 2A has a chute damper 22 that rectifies the dispensing direction (falling direction) while buffering the impact when the discharged rose that flows down in the chute 20a hits the surface on the chute center line side. A damper device 20A is provided.

  That is, the chute damper device 20A rectifies the falling direction of the roses paid out by the plate-like chute damper 22 that is suspended and arranged at the opening 200 of the chute 20a. As shown in FIG. 2B, the chute 20a is arranged in an eccentric manner from the center line of the chute 20a in the advancing direction, and is curved with the chute center line side inward, and the chute 20a lower end inner peripheral surface It exhibits a function of guiding the fall of the dispensed rose so that it falls within a predetermined range from the extended line of the chute center line along the chute center line.

  As shown in FIG. 2B, the chute damper 22 is divided into two damper plates 22a and 22b at the center and arranged in parallel on the left and right plates, and the damper plates 22a and 22b. The shafts 221 and 222 arranged so as to be axially rotatable on the same straight line in the horizontal direction are connected to the upper end of each of the shafts, and are individually pivotally supported so that the lower end can be swung.
