DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. The drawing shows, as an example of an article, an article supply apparatus used for an operation of arranging and supplying a large number of fruit and vegetables one by one. In FIG. Arranged between the conveyor 2 and the sorting conveyor 3 arranged at the latter stage of the conveying path, and arranged in the center of the conveying path while dispersing a large number of fruit and vegetables A supplied from the receiving conveyor 2 back and forth ( (For example, one row), and are transferred one by one to the central portion of the receiving rollers 3a constituting the sorting conveyor 3.

The above-mentioned article supply apparatus 1 is shown in FIGS.
As shown in FIG. 4, the areas a and c set on the transport path
In addition, a large number of support rollers 6 are arranged in the transport direction at intervals before and after fruit and vegetable products A of an arbitrary size (for example, large, medium, and small) are placed, and a region set in an intermediate portion between the regions a and c. b
In addition, a belt conveyor 4 formed in a transport width on which the fruit and vegetables A are placed is arranged in the transport direction.

The support rollers 6 arranged in the areas a and c are formed hollow or solid, for example, of a material such as synthetic resin, metal, wood or the like, and have the same outer diameter from the free end side to the base end side with the roller peripheral surface. (For example, a cylindrical shape, a cylindrical shape, or another similar shape). Note that the roller peripheral surface may be formed in a shape (for example, a conical shape) having a large diameter from the free end side toward the base end side.

On the outer peripheral surface of the support roller 6, for example,
A portion that imparts contact resistance, such as a ridge or a protrusion, may be formed or provided, or the roller peripheral surface may be formed or covered with a member having a large contact resistance, such as a soft resin or a synthetic rubber.

The support roller 6 rotatably bears a base end of a support shaft 7 fixed to the center of the roller by a bearing portion 8 fixed to the mounting frame 5, and a pulley fixed to the base end of the support shaft 7. A drive belt 11 (for example, a round belt, a flat belt, or the like) is stretched (for example, stretches across the figure of eight) between a rotating shaft 9 and a rotating shaft 10 that is suspended on both lower sides of the transport path.

The drive motor 12 with a speed reducer, which is disposed at the lower part of the starting end, is connected to the sprockets 13 and 14 and the drive chain 1.
5, the rotating shaft 10 is synchronously rotated, and the rotating force is transmitted to the support shaft 7 via the drive belt 11, so that the support rollers 6 arranged on both sides of the conveying path are rotated in the conveying direction.

As shown in FIG. 2, the support rollers 6 arranged along the entire length of the area a carry the drive belt 11 around a large-diameter shaft portion 10a formed on the shaft peripheral surface on the starting end side of the rotating shaft 10 and convey it. The fruits and vegetables A rotate quickly in the direction of movement (centering) toward the center of the road.

The supporting roller 6 arranged between the start end and the end of the area c has a drive belt 11 stretched around a small diameter shaft portion 10b formed on the shaft peripheral surface of the intermediate portion of the rotating shaft 10, and a belt, which will be described later. It rotates slightly faster or at the same speed as the conveyor 4. Further, when a resistance greater than the rotational force of the roller itself is applied, it is provided so as to be able to slip. For example, the support roller 6 and the support shaft 7 or the rotary shaft 10 and the drive belt 11 are slipped to transport the fruit and vegetable A The speed is reduced or the transport is stopped, and fruit products A are temporarily stocked on the transport path.

The support rollers 6 arranged at the end of the area c are
Shaft portion 1 having the maximum outer diameter formed on the peripheral surface of the end shaft of rotating shaft 10
The drive belt 11 is stretched around 0c, and rotates faster than the rotation speed of the support rollers 6 arranged immediately before the terminal end. When the fruits and vegetables A are transported on the support roller 6, the fruits and vegetables A are accelerated and transported in the transport direction, and the fruits and vegetables A arranged in the center of the transport path are separated at equal intervals in the front-rear direction to receive rollers 3a of the sorting conveyor 3. ... Transfer one by one.

In the embodiment, the rotation speed of the support roller 6 is variably adjusted by the difference in the outer diameter of the shaft portions 10a, 10b, 10c formed on the rotation shaft 10. The rotation speed of the support roller 6 may be variably set by changing the outer diameter of the fixed pulley 9. In addition, even if the support rollers 6 in the regions a and c are rotated at the same speed, an effect of centering the fruit and vegetable A can be obtained.

As another rotation method, the support rollers 6 arranged on the entire length or a part of the transport path are rotated, for example, via a sprocket and a chain, or independently or interlocked by rotating means such as a built-in or directly connected motor. Alternatively, the support roller 6 may be rotated by pressing a member such as a belt or a rubber roller against the lower peripheral surface of the support roller 6.

The support rollers 6 arranged in the areas a and c are:
The support rollers 6 are arranged so as to have an inverted C-shape with respect to the transport direction (for example, a state in which the inner ends of the support rollers 6 are delayed with respect to the transport direction, and the outer ends advance). In the embodiment, the long supporting rollers 6 are arranged on one side of the conveying path, and the short supporting rollers 6 are arranged on the other side of the conveying path. They may be arranged on both sides. Note that, similarly to the above, the support rollers 6 are arranged in a region b of the embodiment described later.

As shown in FIGS. 5 and 6, the support rollers 6 in the areas a and c and the area b to be described later are gradually shifted to the horizontal direction (in the order of the areas a, b and c) gradually in the transport direction. The fruit vegetables A are moved (centered) toward the center of the conveyance path placed on the support roller 6.

For example, the support roller 6 in the area a is set to a large angle θ ₁ (for example, about 13 degrees), and the support roller 6 in the area c is set to an angle θ ₃ (for example, about 3 degrees) smaller than the above-described angle θ _1. Degrees). The support roller 6 in a region b described later is set to an angle θ ₂ (for example, about 8 degrees) smaller than the angle θ _{1 and} larger than the angle θ _3. May be changed to any angle.

The support rollers 6 in the areas a and c and an area b to be described later are inclined at an inclination angle θ ₄ (for example, about 3 degrees) gradually increasing from the center of the conveyance path toward both sides of the conveyance path. Then, the fruit vegetable A placed on the support roller 6 is moved (centered) toward the center of the transport path.
It is also possible to change the support roller 6 on both sides to any inclination angle theta _4.

As shown in FIG. 7, the belt conveyor 4 disposed in the area b has a roll 21 which is mounted near the support roller 6 at the end of the area a and a support roller 6 at the start end of the area c. A feed belt 22 formed to have a conveyance width on which the fruit vegetables A are placed (for example, in one row) is stretched between the roll 21 and the roll 21 which is arranged close to the shaft.

A rotation motor 23 with a speed reducer disposed at the lower end on the end side rotates the feed belt 22 in the conveying direction via pulleys 24 and 25 and a drive belt 26, and reduces the rotation speed of the feed belt 22. The speed is set so as to be faster than the support roller 6 in the area a and slightly lower than the support roller 6 at the start end of the area c.

The supply amount detector 27 disposed above (or on the side or below) the region b is constituted by, for example, detecting means such as a photoelectric sensor or an imaging camera, and supplies the fruit and vegetable A conveyed by the feed belt 22. The amount (for example, interval, speed, number) is detected, and the supply amount of fruit and vegetable A is determined based on the detected data.

For example, if a large number of fruits and vegetables A are stagnating on the belt conveyor 4, it is determined that the supply amount is large, and if the fruits and vegetables A are intermittently conveyed, it is determined that the supply amount is small. The rotation speed of the belt conveyor 4 disposed in the area b is controlled according to the supply amount.

When it is determined that the supply amount is larger than the preset supply amount, the belt conveyor 4 disposed in the area b is rotated quickly. When it is determined that the supply amount is small, the belt conveyor 4
Slow down the rotation speed. Further, the support rollers 6 arranged in the area c may be rotated in synchronization with the rotation speed of the belt conveyor 4.

On the other hand, as shown in FIG. 4, a diamond, a sphere, or the like
A plurality of guide rollers 16 formed in an arbitrary shape such as an elliptical shape are arranged in the width direction, and are arranged in a plurality of rows so as to gradually decrease in the transport direction.

The guide roller 16 has a support shaft 17 inserted in the center of the roller supported on a support frame 18 provided on both sides on the end side, and gradually becomes higher from the center of the conveyance path to both sides of the conveyance path. It is arranged as follows. The guide rollers 16 arranged in front and rear are inclined at an angle at which the fruit and vegetables A are transferred and guided with respect to the receiving rollers 3a constituting the sorting conveyor 3, and are aligned at the center of the transport path. Fruit A
The transfer guide is performed toward the center of the receiving rollers 3a.

At the upper portion on both sides of the transport path, a transport guide 19 is installed at an interval and an angle at which the fruits and vegetables A are guided toward the center of the transport path. The transport guide 19 may be provided only on both sides of the starting end of the transport path, and the fruit product A can be centered even if the transport guide 19 is removed.
