Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a conveying and sorting device for conveying various types of articles and sorting the articles by carrying them out at a predetermined position.

[Technical background of the invention]

As this type of device, the applicant previously proposed Patent Application Nos. 71777 and 71778 filed in 1982.

In both of these devices, a second conveyor is pulled out and installed laterally from a first conveyor, and a plurality of conversion rollers having the same conveyance directionality as the second conveyor are provided at the intersection of these conveyors. ,
A non-driven sliding means having the same conveyance directionality as the first conveyor is provided between these conversion rollers so that the goods on the first conveyor can be moved up and down.
If the goods are not to be conveyed to the second conveyor, the sliding means is raised and the goods are caused to slide on the sliding means and pass through the intersection by the conveying inertia of the first conveyor or the drive roller provided upstream of the intersection. ,
When carrying out the article to the second conveyor, the sliding means is lowered, the article is supported on the conversion roller, and the article is latched to the upper end of one of the machine frames on both sides supporting the conversion roller. The paper was conveyed to a second conveyor via a conversion roller.

[Problems with background technology]

The belt 16 is constructed by forming a concave portion on the upper side of the winding portion.

Each sorting section 2 is provided with a roller conveyor 21 and a pair of endless conveyor belts 22, and when carrying out articles from each sorting section 2 to one side or the other, the roller conveyor 21 When the articles are conveyed as they are without being carried out from each sorting section 2, they are passed through the sorting section 2 by the pair of endless conveyor belts 22.

Each of the roller conveyors 21 described above is shown in FIGS. 3 and 2.
As shown in the figure, a plurality of transport rollers 23 are provided close to the guide pulley 18 on the upstream side of the sorting section 2 and spaced apart from the guide pulley 18 on the downstream side. The shaft racks are sequentially arranged in parallel from one side of the frame 11 to the outside of the other side (or from the other side to the outside of one side) via a pair of machine frames 24 and 25 in a direction crossing at right angles. An endless V-belt 26 disposed along the machine frame 25 on the downstream side is in contact with the lower part of each conveyance roller 23, and this V-belt 26 is attached to one side of the sorting section 2. The conveyor rollers 23 are rotated by a motor 27 provided on the outside (or on the outside of the other side). It is designed to rotate with a conveyance directionality toward the other side (or one side) intersecting at right angles.

The conveyance surface of each of the roller conveyors 21 by the conveyance rollers 23 is set at a slightly lower position than the conveyance surface of the belt 16 of the conveyor 1.

As shown in FIGS. 3 and 4, each pair of endless conveyance belts 22 are provided between the conveyance rollers 23 of the roller conveyor 21 of the sorting section 2, and are arranged between the guide pulleys 18 on the downstream side of the sorting section 2. One driving pulley 30 close to the guide pulley 18 on the upstream side of the sorting section 2, and a pair of driven pulleys 3 close to the guide pulley 18 on the upstream side of the sorting section 2.
1. It is wound around a pair of guide pulleys 32 upstream of the drive pulley 30 and a pair of tension pulleys 33 below the guide pulley 32, and both ends of the shaft _30a of the drive pulley 30 are Pair bearing 3
4, and each guide pulley 32 and tension pulley 33 are supported by a pair of support frames 36 supported by a pair of bearings 35 on the shaft _30a . Each driven pulley 31 is mounted on a shaft at the tip of a pair of belt rails 37 attached to each support frame 36 .

The pair of endless conveyor belts 22 have the same conveyance directionality as the conveyor 1 by driving the drive pulley 30 by a motor 38 provided adjacent to the motor 27 of the roller conveyor 21. It rotates clockwise as shown in Figure 4.

Note that the tension pulley 32 is attached to the support frame 3.

The lower part of each belt rail 37 of the pair of endless conveyor belts 22 is integrally connected by a bracket 39, and the tip of the rod 40a of the air cylinder ₄₀ pivotally supported on the frame 11 is attached to the lower part of the bracket 39. By this, each belt rail 37 and each support frame 36 on which each driven pulley 31 is mounted are connected to the shaft 30 _a of the drive pulley 30.
The conveying surface by the pair of endless conveyor belts 22 is the roller 2 of the roller conveyor 21.
3, it is designed to move up and down with respect to the conveyance surface.

Further, among the conveyance rollers 23 of each roller conveyor 21, an annular stopper 43 is fitted to the conveyance roller 23 adjacent to the endless conveyance belt 22 so as to be movable in the axial direction of the conveyance roller 23. It is fixed with a fixing screw (not shown) or the like.

Although not shown, there is a conveyor 1 on the upstream side of each sorting section 2 of the conveyor 1.
Detection means for detecting the type of the item above is provided, and each detection means is connected to the sorting section 2 downstream of the detection means.
When an item to be carried out is detected, the air cylinder 40 of the sorting section 2 is activated and the rod 40 _a
is shortened from the state shown in FIG.
Then, after a predetermined period of time has elapsed, the air cylinder 40 is operated to return and the rod _40a is extended to the state shown in FIG. Conveyor belt 2
2 is on the rise.

With the above-described configuration, this conveyor sorting device sequentially carries various kinds of articles into the upstream end of the conveyor 1 and conveys them to the downstream side, and each detection means of the conveyor 1 detects the items. When the type of the item is detected and the item is transported to the side in the sorting section 2 on the downstream side, the pair of endless conveyor belts 22 of the sorting section 2 on the downstream side are moved below the conveyor rollers 23 of the roller conveyor 21. During this time, the item is carried out laterally by the roller conveyor 21. If the item is not carried out laterally at the sorting section 2 on the downstream side, the item is carried out laterally by the roller conveyor 21. Set the side sorting section 2 to 1
The items are passed through a pair of endless conveyor belts 22 and conveyed to the next sorting section 2, thereby carrying out predetermined types of articles from the corresponding predetermined sorting section 2 and sorting the articles by type. be.

At this time, since the roller conveyor 21 and the pair of endless conveyor belts 22 of each sorting section 2 are both driven, it is possible to convey and sort the articles at high speed, and even when the articles pass through the sorting section 2, the conveyor belts 22 are driven. Since the sorting section 2 receives force, the length of the sorting section 2 can be increased to allow transportation and sorting of large items.

Furthermore, when carrying out the articles from the sorting section 2, the articles are stopped by the annular stopper 43 fitted to the conveying roller 23 of the roller conveyor 21, so that the direction of the articles to be carried out does not go out of order. Up,
Since the position of this stopper 43 is adjustable, even if the size of the items to be conveyed and sorted changes, the items can be supported in the center of the roller conveyor 21 and carried out in a stable state.

Further, the endless conveyor belt 22 moves up and down centering around the drive pulley 30 on the downstream side, and does not move up and down as a whole, so the structure for lifting and lowering is simple.

Furthermore, when the items being conveyed by the conveyor 1 get too close to each other, the drive of the endless conveyor belt 22 of the sorting section 2 is temporarily stopped, thereby temporarily stopping the items on the upstream side and moving the items on the downstream side. It is possible to maintain an appropriate distance between the two.

In this embodiment, the entire transport conveyor 1 is constructed of one long belt 16, but the configuration is not limited to this, and the configuration may be such that each sorting section 2 is connected by a plurality of belt conveyors. ,
A roller conveyor may be used instead of a belt conveyor.

〔Effect of the invention〕

As described above, according to the present invention, various types of items are sequentially brought in and conveyed to a conveyor that connects a plurality of sorting sections, and the corresponding types of items are carried out laterally at a predetermined sorting section. In a conveyor sorting device that sorts items, an endless conveyor belt is used to pass the items through the sorting section to provide conveying force to the items, so the length of the sorting section is made longer to sort large items. However, the speed of the items does not decrease when passing through the sorting section, allowing high-speed conveyance and sorting, and the conveyance speed of the articles is stable. As a method, the endless conveyor belt is lowered to support the articles on the roller conveyor, and the articles are held in place by annular stoppers fitted to the rollers of this roller conveyor, so that the articles can be reliably and correctly oriented. Items can be carried out, and since the position of this stopper is adjustable, items can be carried out while being supported in the center of the roller conveyor, depending on the size of the items to be conveyed and sorted. Since the entire structure does not move up and down, the structure for lifting and lowering can be made simply.
