Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of use) The present invention relates to a transfer device of a sorting system for reliably transferring long workpieces to be sorted, such as green asparagus, one by one.

(Prior Art) As a transfer device for a sorting system of this type, a hard belt having a substantially same shape as a workpiece to be sorted is often a simple belt conveyor mechanism. In this belt conveyor mechanism type transfer device, for example, it is easy to arrange works one by one in parallel at a predetermined position by a parallel device and sequentially transfer the works in parallel one by one to another position. Typical examples of such workpieces are industrial products, but in the case of long agricultural products that are not necessarily straight, such as green asparagus, the degree of hardness and softness, the size of the shape, and the size of the weight. Are large or subtly different for each, and damage or damage to the belt conveyor mechanism described above,
There was a problem because the putting in and out was not smooth.

(Problems to be Solved by the Invention) As described above, in the transfer device of the sorting system according to the related art, the degree of hardness and softness, the size of the shape, and the size of the weight are not necessarily linear, but are large or subtle for each individual. In the case of different works, there is a problem in that the above-mentioned belt conveyor mechanism is damaged or is not smoothly taken in and out, so that proper transfer cannot be performed.

Therefore, the present invention is to provide a transfer device of a sorting system that can accurately transfer one piece to a predetermined position even in the case of a long work such as an agricultural product.

[Structure of the Invention] (Means for Solving Problems) The present invention is characterized by taking the following means in order to solve the problems and achieve the object. That is, the present invention is a transfer device of a selection system for transferring a plurality of long-sized sorting target works supplied from the outside in a predetermined direction and arranging them one by one in parallel at one position to another position. In the above, a box body and a rotary cylinder body provided in the box body and having a vacuum inside are formed, and slits are formed at equal intervals in the circumferential direction of the rotary cylinder body. A notch is formed to expose at least two slits of
A suction drum configured to suck the work by suction pressure at the one position by the exposed at least two slits, and the work is transferred to another position by rotation of the rotary cylinder, and transferred to the other position. A first pulley for transferring the work to a distant place, which is provided coaxially with the rotary cylinder, and a second pulley which is spaced apart from the first pulley, and the first and second pulleys. The work piece transferred to the other position by the suction drum has a belt suspended between the pulley and a plurality of separation claws provided at predetermined intervals in the longitudinal direction of the belt. Hold with the separation claw,
The held work is a transfer device of a sorting system including a transfer conveyor mechanism configured to be transferred to a distant position separated from the other position.

(Operation) According to such a configuration, only the slit exposed by the notch of the suction drum serves as a suction portion, and the workpiece is sucked by this suction portion. Without receiving the work, the work can be reliably delivered to the transfer conveyor mechanism, and the work can be transferred to the distance while being held by the separation claw of the transfer conveyor mechanism.

(Embodiment) An embodiment of a transfer device of a sorting system according to the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing the transfer device of this embodiment in relation to a parallel device and a belt conveyor mechanism with pockets, FIG. 2 is a front view of the same, and FIG. 3 is a schematic view showing a cross section of the device of this embodiment. FIG. 4 is a schematic view showing the relationship between the transfer conveyor mechanism and the belt conveyor mechanism with pocket of the apparatus of the embodiment.

In FIG. 1 and FIG. 2, the works P, which are green asparagus, are stacked on the parallel device 10 at the position S1.
By the operation, one by one is arranged in parallel, and the transfer device is at position S2.
Passed to 20. The transfer devices 20 are transferred one by one from the positions S2 and S3 and are delivered to the belt conveyor mechanism 30 with pockets at the position S4. The outer shape of the work P transferred by the belt conveyor mechanism 30 with pockets is inspected by an outer shape inspection device (not shown) provided on the downstream side, and the work P is sorted and sorted according to grade.

Next, the configuration of the transfer device 20 will be described in detail.

As shown in FIGS. 1 and 2, the transfer device 20 basically has a suction drum 20A for receiving the works P one by one from the parallel device 10 and another work P for taking out the works P from the suction drum 20A. It is composed of a transfer conveyor mechanism 20B for transferring to a position.

Here, the suction drum 20A, as shown in FIG.
This is a configuration in which the rotary cylinder 20Ab is housed in 0Aa. And
The rotary cylinder 20Ab has slits 20Ac1 at equal intervals in the circumferential direction.
.About.20Ac8 are formed, and the box body 20Aa is formed with a cutout portion 20Ad so as to expose two slits (20Ac1 and 20Ac2 in the figure) of the rotary cylinder body 20Ab. In this case, the work P is transferred to the position S3 by the rotation of the rotary cylinder 20Ab while sucking the work P at the position S2 by pulling the exposed slits (20Ac1 and 20Ac2 in the figure). Also, the rotating cylinder
The 20Ab has a bearing and a pulley 20Ae (not shown) in the axial direction, and receives power from the pocket conveyor mechanism 30 to rotate. Further, the rotary cylinder 20Ab is connected to a vacuuming hose 20Af connected to a vacuum pump at its axial end so as to vacuum the rotary cylinder 20Ab.

On the other hand, the transfer conveyor mechanism 20B is constituted by a belt 20Be hung over a pulley 20Ba, an intermediate pulley 20Bb, 20Bc, and an end pulley 20Bd provided on a rotary cylinder 20Ab, and the work P is sucked onto the belt 20Be. Separation claws 20Bf taken out from the drum 20A are provided at predetermined intervals.

On the other hand, the transfer conveyor mechanism 20B and the pocketed conveyor mechanism 30 are as shown in FIG. That is,
The separation claw 20Bf of the transfer conveyor mechanism 20B corresponds to the pocket 30A provided on the belt of the conveyor mechanism with pocket 30. Specifically, the pocket 30A is configured by providing a fall prevention claw 30Ab provided in the longitudinal direction of the work storage portion 30Aa, and the separation claw 20 is provided in the gap of the fall prevention claw 31Ab by circling the belt 20Be.
