Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a material feeding device that feeds a plurality of materials arranged side by side in the horizontal direction in the vertical direction sequentially from the end.

(Prior Art) For example, in the case of feeding wood to a finger composer, it is necessary to feed a plurality of timbers arranged side by side in the vertical direction in order from the end.

In the case of feeding such materials, it is necessary to feed the materials one by one while surely separating them, but the conventional feeding device has room for improvement in this respect.

(Problems to be Solved by the Invention) The present invention solves the above-mentioned conventional problems and feeds a plurality of materials arranged side by side in the lateral direction in the longitudinal direction while surely separating the materials one by one from the end. The purpose of the present invention is to provide a material feeding device that can do this.

(Embodiment) A material feeding device of the present invention will be described below with reference to an embodiment shown in the drawings.

1 and 2 show a material feeding device of the present invention, in which the material feeding device (1) is provided with a cradle (a) on which a plurality of materials (20) are fed in a state of being arranged in the lateral direction. 2b).

A cylinder (4) is provided at one end of the pedestal (2b), and the cylinder (4) pushes the material (20) on the pedestal (2b) laterally (at the tip of the plunger). Push plate (5) is fitted).

Next, below the other end of the pedestal (2b), one end of the lateral feed belt (7) is provided in close proximity to the pedestal (2b) with a step corresponding to the thickness of the pedestal (2b).

In the illustrated embodiment, the transverse feed belts (7) are arranged in four rows.

Here, the feeding speed of the lateral feed belt (7) is a / b times the extension speed of the pushing means (the longer vertical length of the cross section of the material (20) is a, and the shorter horizontal length thereof is b). ) More than that.

The other end of the lateral feed belt (7) is close to one side of the vertical feed belt (9) running at a right angle to the other end.

In the illustrated embodiment, a ruler (10) is projected above the other side of the vertical feed belt (9) in proximity to it.

Next, a support arm (2a) is provided so as to project from the main body (2) on the boundary between the pedestal (2b) and the transverse feed belt (7).

The support arm (2a) is equipped with a cylinder (12) which is inclined downward toward the pedestal (2b).

The tip of the plunger (13) of the cylinder (12) is rotatably attached to the back surface above the center of gravity of the guide plate (15) as shown in FIG.

In the illustrated embodiment, a pair of metal fittings (16) is fixed to the back surface of the guide plate (15), and a ring (18) at the tip of the plunger (13) is attached to a shaft (17) passed between the metal fittings (16). ) Is rotatably attached.

The guide plate (15) is adjusted so as to be pressed against the end surface of the support arm (2a) and hang down on the boundary between the pedestal (2b) and the lateral feed belt (7) when the plunger (13) is contracted.

Next, the lateral feed belt (7) and the vertical feed belt (9) are each driven by a motor (not shown).

The operation of the material feeding apparatus of the present invention shown in the above embodiment will be described below.

That is, for example, a plurality of materials (20) as shown in FIG. 4 (the vertical length a of the cross section of which is longer than the horizontal length b) are arranged in the horizontal direction so that their widest plate surfaces are in close contact with each other. In this state, it is sent between the guide plate (15) on the pedestal (2b) and the push plate (5) of the cylinder (4).

That is, the material (20) is guided by the guide plate (15) hanging on the boundary between the pedestal (2b) and the lateral feed belt (7) and supplied onto the pedestal (2b).

Then the cylinder (12) is driven and its plunger (13)
Is extended (state of the dashed line in FIG. 2).

As a result, the guide plate (15) attached to the tip of the plunger (13) extending above the material (20) is attached to the material (2).
It will be positioned above (0).

However, since the guide plate (15) is rotatably attached to the tip of the plunger (13) slightly above the center of gravity of the guide plate (15), the guide plate (15) tries to hang down, and the upper end of the material (20) near the lateral feed belt (7). You will lean against it.

In this state, the cylinder (4) is driven so that the plunger is gradually extended and the end material (20) is extruded from the pedestal (2b) onto the transverse feed belt (7).

As a result, the material (20) at the end is running transverse feed belt
When the foot is taken by (7), it falls on the transverse feed belt (7) (the state shown by the dashed line in FIG. 2).

When the material (20) at this end falls, the guide plate (15) presses the upper end of the guide plate (15) to assist the fall, and immediately the next material (20).
Since it will lean against the upper end of the sheet, the next material (20) will not be dragged and only one of the ends will be separated and sent by the transverse feed belt (7).

Here, the cylinder (4) grows slower than the lateral feed belt (7), so when one material (20) reaches the vertical feed belt (9), the next material (20) Fall from the pedestal (2b) onto the transverse feed belt (7).

The material (20) on the transverse feed belt (7) is then fed onto and passed over the longitudinal feed belt (9).

As a result, the material (20) is placed on the vertical feed belt (9), fed vertically along the ruler (10) and delivered to the next step.

(Effects of the Invention) The embodiment of the material feeding device of the present invention is as described above, and the effects thereof are listed below.

(1) The material feeding device of the present invention has the construction described in the utility model registration claim, and is rotatably attached to the tip of the cylinder and the plunger of the cylinder that are mounted so as to incline downward toward the cradle. Since the guide plate is extended, the guide plate leans against the upper end of the end material when the plunger is extended, and as a result, the material is surely separated one by one from the end material and sent.

(2) The material feeding device of the present invention has the same construction as above. Especially, since the guide plate is attached to the tip of the plunger of the cylinder above the center of gravity of the device, when the plunger is contracted, the guide plate is attached to the pedestal and the lateral feed belt. It hangs on the boundary of the and acts as a guide for the material.
