The positional relationship between the sorting and feeding device B and the sorting conveyor C is as shown in FIG. D is a fruit sorting device, and E is a plurality of sorting conveyors. The moving direction of the sorting conveyor E is orthogonal to the moving direction of the sorting conveyor C, and is provided on both sides of the sorting conveyor C, respectively. F is an alignment width shifting device, and G is a box packing device.

In FIG. 5, B is an alignment feeding device, 31 is an alignment conveyor of the device, 32 is a supply gate provided above an end of the conveyor, and 50 is a curry. C
Is a sorting conveyor provided below the alignment conveyor,
Numeral 41 denotes a sorting dish constituting the conveyor.

The curry 50 stored and shipped by a producer in a dedicated container is collected at an agricultural cooperative, refrigerated, and then discharged from the container onto a conveyor of an alignment supply device B by an automatic damper A. And the lowermost alignment conveyor 3
1, the curies 50 are arranged one by one at predetermined intervals and conveyed, and the supply gate 32 is opened at the same pitch as the timing at which the fruit sorting tray 41 comes down, and the sorting conveyor C moving toward the fruit sorting device D is opened. Are sequentially supplied to each of the fruit selection dishes 41 at a constant pitch interval.

[0005] Next, the curries are judged one by one by a camera-type fruit sorting device D one by one, and only curies of the same grade are supplied to the aligning and aligning device F via the respective sorting conveyors E to perform sorting and sorting. After wrapping and packing by the box packing device G, it is shipped.

1 is a side view of a constant-pitch feeding device for long vegetables according to one embodiment of the present invention, FIG. 2 is a sectional view taken along the line II-II of FIG. 1, and FIG. It is. The constant-pitch supply device of the present invention is installed at a connection portion between the alignment supply device B and the sorting conveyor C in the automatic packaging system shown in FIG.

In FIG. 1, reference numeral 1 denotes a frame provided adjacent to the aligning and feeding device B, and 2A and 2B denote sprockets pivotally supported by the frame. A plurality of the sprockets are provided along a traveling direction of a chain described later. 3 is a guide car provided near the sprocket 2B.
a is a plurality of guide notches provided around the guide vehicle, 4 is a chain that meshes with the sprockets 2A and 2B, 9 is a horizontal mounting shaft provided between both side chains, and 8 is the same mounting shaft. A fruit selection plate fixed to the shaft, 5 is a guide lever mounted diagonally upward to one end of the mounting shaft 9, 5a is a cam follower provided at the end of the guide lever, and 7 is a mounting. A guide lever 7a is attached to the other end of the shaft 9 obliquely downward, a cam follower 7a provided at an end of the guide lever,
12A and 12B are a pair of guide rails through which the cam follower 5a passes. The guide rails are provided on the vertical part and the horizontal part, and are not provided on the bent part. 13A and 13B are belt wheels, and 14 is a belt. Numeral 45 denotes a sorting plate of the aligning and feeding device B, and numeral 50 denotes a curry.

As shown in each figure, a chain 4 is attached to a plurality of sprockets 2A and 2B (here, only one set of right and left is shown) connected to the end of the aligning and feeding device B and supported by the frame 1. It is stretched so that it can rotate endlessly,
Fruit selection dishes 8 are attached to the chain 4 at predetermined intervals. The fruit sorting dish 8 is fixed to a horizontal mounting shaft 9, and both ends of the mounting shaft 9 are rotatably mounted on the chain 4, respectively.
The outer periphery of 2B is engaged.

A guide lever 5 having a cam follower 5a is attached to one end (the left side in FIG. 2) of the mounting shaft 9 and a tip is attached to the other end (the right side in FIG. 2). Guide levers 7 each having a cam follower 7a are attached, and a trajectory A is provided in a vertical straight section and a horizontal straight section of the rotation trajectory A of the chain 4.
A pair of guide rails 12A and 12B are provided along the axis, and the cam follower 5a of the guide lever 5 is engaged between the guide rails 12A and 12B. At this time, the guide lever 5 is set at an angle (θ = 4
5 °) and is mounted on the mounting shaft 9 so that the fruit selection tray 8 is held horizontally and can move in a straight section.

On the other hand, in the curved section of the trajectory A of the chain 4 on which the sprockets 2A and 2B are installed (no guide rail is provided here), the outer periphery is provided on one chain side (the right side in FIG. 2). A guide wheel 3 having a plurality of guide grooves 3a and having the same diameter as the sprockets 2A and 2B is installed with the center axis shifted with respect to the sprocket 2B (in this example, the center axis is shifted in the 45 ° direction). The sprockets 2B and 3 rotate at the same speed by a belt 14 stretched between respective belt wheels 13A and 13B. When the guide lever 7 passes through the curved section together with the chain 4, its cam follower 7 a engages with the guide notch 3 a of the guide wheel 3. Thus, in FIG. 1, the turning distance and speed of the locus A of the chain 4, the locus B of the cam follower 7a, and the locus C of the cam follower 5a in the respective curved sections are equal, whereby the fruit selection tray 8 is held horizontally. The curved section can be moved in the state in which it is held.

The operation of the constant pitch supply device will be described below. The fruit selection plate 8 attached at predetermined intervals to the chain 4 that rotates endlessly by the sprockets 2A and 2B
The guide lever 5 engages with the guide rails 12A and 12B in the straight section of the rotation locus, and the guide lever 7 in the curved section.
Are engaged with the guide grooves 3a of the sprocket 3 and are constantly rotated horizontally. When the curry 50 that has been aligned and transported at a predetermined interval on the sorting tray 45 of the upstream sorting and supplying device B reaches the end of the device B, the rotation trajectory of the rotation trajectory just coincides with the supply timing. This curry 5 is provided by the horizontal sorting tray 8 rising from below.
After being picked up by scooping, 0 is conveyed to the downstream side at a constant pitch interval via the curved section and the horizontal curved section of the trajectory while being aligned in the correct direction.

After that, the curry 50 is discriminated by the camera type sorting device D, sorted by grade by the sorting conveyor E, the aligning width adjusting device F and the box packing device G, packed in a box, and then shipped.

As described in detail above, according to the constant pitch feeding apparatus for long vegetables of the present invention, the long vegetables supplied from the upstream side engage with the guide rails in the straight section of the rotation locus. In the curved section, the first guide lever is picked up from below by a sorting tray which is held horizontally by a second guide lever which engages the guide notch of the guide wheel, whereby it is elongated. The longitudinal direction of the vegetables is always held at a substantially right angle to the transport direction, and the vegetables are transported at a constant pitch, so that the discriminating operation by the fruit sorting device can be performed smoothly and automatically without manual rework. You will be

In addition, since the impact when receiving the long vegetables by the fruit selection dish hardly occurs, it is performed quietly and accurately.
This has the effect of preventing the occurrence of troubles such as a decrease in commercial value due to scratches on the vegetables.

[0020]

According to the constant pitch feeding device for long vegetables of the present invention, the long vegetables supplied from the upstream side are guided by the first guide lever which engages with the guide rail in the straight section, and are guided in the curved section. The picking plate held horizontally by the second guide lever engaging with the notch for guiding of the car is picked up from below by the scooping plate, whereby the posture of the long vegetable is always in the transport direction in the longitudinal direction. Therefore, the vegetables can be always stably transported in the same posture at a constant pitch, and the vegetables can be prevented from being scratched.
