Description

Detailed Description of the Invention (Industrial Application Field) The present invention is used in the assembly processing and packaging industries, etc., to quickly turn over articles with two sides using a compact device with simple operation. A device capable of reliably transporting and reversing multiple types of articles with different sizes, thicknesses, and shapes without clogging the transfer path, and a device capable of continuously and highly efficiently sorting the front and back of articles, and The present invention relates to a sorting and reversing device that can perform a reversing operation in a series of operations.

(Prior Art) Conventionally, when supplying an article having a front and back side, for example, a bottle lid, it is necessary to match the concave part of the lid with the opening of the bottle. Several devices have been developed to automatically perform this reversal.

For example, as shown in FIG. 14, if a rectangular tubular chute 50 formed in a substantially semicircular shape is installed vertically and the article 52 of the feeding member 5l is introduced from the upper entrance of the chute 50, the article 52 will be It falls along the inner wall of the chute 50 due to its own weight, and while reaching the outlet at the bottom, it is turned over and discharged by the take-out member 53.

Further, as shown in FIG. 15, a chute 55 (twist chute) consisting of a guide member 54 having a predetermined slope at the entrance and exit and gradually forming a twist of 180' is installed, and the upper part of the chute 55 is When the article 52 is thrown in from the entrance, the article 52 falls by its own weight along the twisting guide member 54, and while changing its posture and reaching the lower outlet, the article 52 is turned upside down and discharged from the take-out member 53. Ru.

As described above, in order to invert the article 52, it is necessary to sort the front and back of the article into one side in advance, so a pre-processing device (auto feeder) for this inverting device has also been developed.

For example, as shown in FIGS. 12-13, the device is composed of an inclined bowl 60 and a rotary table 6l, and a rotary table 61 is provided. A rotating disk 62 is provided in the center of the bull 6l, and a tooling guide 63 and a workpiece shifting guide 64 are provided on the circumferential side of the rotating disk 62.

In other words, the workpieces input from the bowl 60 and the rotary table 61 into the portion corresponding to the hopper are transferred to the rotary table 6l.
The work is transported from the lower part of the slope to the upper part, and placed on the rotating disc 62 by a workpiece bringing guide 64 provided near the point of contact with the rotating disc 62.

The workpieces are aligned by a tooling guide 63 attached to the outside while rotating together with the rotating disk 62.

(Problem to be Solved by the Invention) However, in the former device for reversing an article, if the gap in the article passage in the rectangular tubular chute is larger than the article, when the article is fed into the chute,
Due to the excessive gap created between the inner wall of the chute and the article, the conveyance posture of the article is abnormally tilted during the fall, and the article becomes clogged inside, making it impossible to supply the article.

In addition, if the size of the passage in the rectangular cylindrical chute does not have enough space to transfer the product, the upper and lower inner walls of the chute may come into contact with the product, making it impossible to transfer the product smoothly or causing it to become clogged inside. It becomes impossible to supply goods.

Therefore, when feeding various products with different thicknesses on an assembly line, it is necessary to select and replace the passage size that matches the product thickness each time, so a large number of chutes corresponding to the type of product thickness must be installed. The assembly line must be temporarily stopped for replacement each time, so the line cannot be operated continuously and production efficiency is significantly reduced.

Furthermore, when replacing chutes with different dimensions, the heights of the inlet and outlet of the chute change, and accordingly the inlet and outlet members connected to the inlet and outlet must be aligned. , the number of work steps increases and efficiency decreases.

The latter reversing device requires a long movement distance for the article to complete the 180° reversal of the article.
The assembly line is extended and a large work space is required, making it impossible to use factory space effectively.

In addition, the interval between the passages of the guide member must be selected and replaced depending on the thickness of the article, so if the thickness of the article differs, it must be replaced each time.As with the former device, the number of parts increases, and the assembly The work is inefficient and cannot be used for mass production.

Furthermore, the sorting device for the articles to be fed to the reversing device described above uses air to determine the alignment of the objects based on the difference in their centers of gravity and their shape, and the sorting mechanism is centrally located. , the conveying part is attached to the outside, making the entire device thicker.

When loading the workpieces into the sorting mechanism, the workpieces are loaded one by one to avoid overlapping, so a large amount of air is consumed to blow out the air.

When changing from sorting one workpiece to sorting another workpiece, it is necessary to adjust the direction of the blowing air nozzle, etc. As the center position of the air blow changes as the diameter and length of the workpiece changes, adjusting the air nozzle requires skill and experience, resulting in poor reproducibility.

Similarly to the above, when changing from sorting one workpiece to sorting another workpiece, it takes time to set up things such as adjusting the position of the guide rail and the width bar (restriction plate).

It cannot be used for workpieces whose shapes have changed and is not versatile, which increases the cost of the product.

Tooling problems for small and thick items are likely to occur in the clearance area between mechanical stationary parts and rotating parts.

In addition, even with regard to other sorting devices that are said to be versatile, it takes time to adjust them due to their fundamental principles, and they cannot respond to changes in the shape of the workpiece.

It had various problems and issues such as.

The present invention has been made in order to solve the above-mentioned problems and problems, and it is possible to quickly turn over an article having two sides with a simple operation and a compact device, and also to turn over a plurality of types of articles having different heights. A versatile device capable of reliably transporting and reversing even articles without clogging the transport path, and a series of operations that perform the above-mentioned reversing work after continuously and highly efficiently sorting the front and back of articles. The purpose of the present invention is to provide a sorting and reversing device that can perform the

(Function) The present invention achieves the following functions by virtue of the above-described configuration.

First, the article sorting and reversing device will be explained.

The articles supplied on the rotating disk enter the article receiving section one by one while rolling inside due to the rotation of the rotating disk, and are sequentially sent to a predetermined discharge position, that is, a pressurized fluid supply section.

Prior to the discharge position. When fluid from a pressurized fluid source is supplied to a through hole in the receiving section for an article that has entered the article receiving section, the article will change depending on its posture and the flow of fluid from the through hole, such as an article having a recess (a bottle). lid, etc.), the positive pressure received when the concave portion corresponds to the through hole and the negative pressure received when the flat part of the article corresponds to the through hole are generated, and the article subjected to the positive pressure is generated. The article is blown away and returned to the rotating disk, and the article subjected to the negative pressure is held in that state while being sucked and pressed against the receiving section, and is transferred to the discharging means.

The articles sorted by the sorting device are transferred from the discharge means to the supply means of the reversing device, and the articles are reversed by the action described below.

In the reversing device, when a pressurized transfer body is used to transfer articles, when a large number of articles arranged on the article supply means are fed one by one to the pressurized transfer body, the articles are removed from the pressurized transfer body by the pressurized transfer body. The article is pressed against a receiving member provided on one side, and is moved along the circular arc of the receiving member in the rotational direction by the rotation of the pressurized transfer body, and when the article reaches the end of the receiving member, its front and back sides are reversed.

Then, when the reversal of the article is completed, the pressure applied to the article by the pressurized transfer body against the receiving member is released, so that the article is transferred to the discharge member and discharged.

In addition, when a rotating body equipped with a large number of pressure members is used to transport articles, when a large number of articles arranged on the article supply means are fed one by one to the rotating body at the bottom, the articles are rotated by the rotating body. The article is pressed against a receiving member provided on the outside by a pressure member attached to the body, and the article moves along the arc of the receiving member in the rotational direction due to the rotation of the rotating body, and the article reaches the end of the receiving member. Sometimes the front and back sides are reversed.

When the reversal of the article is completed, the pressure applied to the article by the pressure member of the rotating body against the receiving member is released, so that the article is transferred to the discharge member and discharged.

Furthermore, when using a clamping type pressure member to transfer articles,
When a large number of articles arranged on the article supply means are fed one by one to the upper part of the transfer path, the articles are held on both sides by a pair of pressurizing members attached to the rotating body and are sent to the lower part of the transfer path. It is transferred as the rotating body rotates, and when it reaches the end of the transfer path, it is turned over and sent out by the sending means.

Then, the gap of the transfer path h formed between the elastic material 9a and the receiving member 5 is set to be slightly narrower than the thickness of the article W to be transferred, and when the article W is supplied from the supply means 6, the article W
Due to the thickness of the pressurized transfer body 9, the elastic member 9a of the pressurized transfer body 9 presses the article W against the receiving member 5 with its elastic force, and is sequentially transferred in the direction of rotation by the rotation of the pressurized transfer body 9 by the drive means 10. be.

Note that the gap in the transfer path h described above is formed in the same manner as the transfer path h shown in the first embodiment.

Furthermore, FIG.
This shows an example of an embodiment in which the axis 1) is connected to the frame 2. 12.1
Three supported rollers 14, 15. An endless flat belt 17 is stretched around the shafts 12. 13 to spring 18, l! l}
When the article W is supplied from the supply means 6, the roller 15 of the pressure transfer body 9 moves the article to the receiving member 5 by its elastic force via the flat belt l7 due to the thickness of the article W. While pressing W, the pressurized transfer body 9 is rotated by the drive means 10 linked to the roller l4, so that the pressurized transfer body 9 is sequentially transferred in the rotational direction and sent to the delivery means 8.

Furthermore, FIGS. 6 and 7 show a fourth embodiment of the article reversing device A according to the present invention, in which a pair of left and right rotating bodies 3a, 3a are mounted on a frame 2, and an article-sized ( The pair of rotating bodies 3a, 3a are supported by shafts 4a, which are arranged opposite to each other, with a transfer path h having a gap larger than (diameter) formed therein.
On the corresponding surface of ?, there is a pressure member formed in the shape of a strip of a predetermined length using a material having elasticity, restorability, and flexibility similar to that of the first embodiment. a, 7a are attached in large numbers in the tangential direction to the rotating bodies 3a, 3a, and the transfer path h
The rotating bodies 3a are attached at an angle to the surface of the rotating bodies 3a so that their free ends face each other inward.

The terminal end of the transfer path h is located at the top of the transfer path h. A supply means 6a is provided so as to face the pressure member 7a, and a supply means 6a is provided at the lower part of the transfer path h, the starting end of which is connected to the pressure member 7a.
A sending means 8a is provided so as to face the parts a and 7a.

Note that the supply means 6a and the delivery means 8a described above are attached to the frame 2 with an inclination that allows the article W to slide under its own weight, but although not shown in the drawings,
It is also possible to employ a configuration in which a commonly used roller or belt conveyor is used to forcibly feed and forcefully send out the material by means of a driving means.

Further, the pressure member 7 is provided opposite to the delivery means 8a.
a, a detachment member e for releasing the article W from 7a,

Next, in FIGS. 8 to 10, reference numeral B denotes an article sorting device, which sorts the front and back of the lids of bottles, etc. from among the articles W mentioned above, and has a concave portion Wa formed on one side of the article W. use something

Then, the rotating disk 2 is attached to the frame 2 by the driving means lO.
0 is rotatably supported on a shaft 21, and this rotating disk 20 has a concave shape on the circumferential side that is one step lower than the rotating disk 20 and is inclined in the opposite direction to the rotating direction to receive an article W as shown in FIG. A large number of sections 22 are arranged at intervals.

Although not shown in the drawings, the receiving portion 22 may be formed parallel to the rotation direction.

Furthermore, as shown in FIG.
It is preferable to adopt a structure in which the angle of inclination can be changed as appropriate.

A cover plate 23 of a predetermined height is provided on the outer periphery of the rotating disk 20 so as to surround it, so that when the articles W are supplied onto the rotating disk 20 and rotated, the articles W are scattered outward. A means 24 for discharging articles is provided on one side of the cover plate 23 at a proper place in the tangential direction of the rotary disk 20. Reference numeral 25 is a drive means for the rotary disk 20, and the rotation of the motor 25 is The signal is transmitted to the shaft 21 via the speed reducer 27.

The article W engaged in the recess of the receiving section 22 is transferred from the lower side of the rotary disk 20 to the upper side while holding the outer peripheral edge of the article W.

Furthermore, due to the inclination of the rotating disk 20, the article W that is not engaged with the recessed portion of the receiving section 22 slides downward under its own weight, and is transferred upward again by the transfer of the rotating disk 20, and is transported upward again to the receiving section 2.
One article W is stored in each of the two compartments.

In addition, holes 28 for pressurized fluid, such as air, are provided at suitable locations, for example, in the center of the receiving portion 22 of the rotary disk 20. As shown in FIG.

Note that the through hole 28 may be formed at a position other than the central part of the receiving part 22. For example, the through hole 28 may be formed at a position eccentric to the receiving part 22, as shown by the imaginary line in FIG. When air is ejected from the through hole 28, the article W is reliably moved to the center of the rotary disk 20, that is, to the lower part of the slope by the air jet force. The air is prevented from flying out to the outside of the cover plate 23 by the jet of air.

The ejection means 24 has a guide 29 whose interval can be adjusted freely.
29 are provided on both sides, so that the transfer interval can be changed arbitrarily by changing the shape of the article W.

30 is a pressurized fluid supply section, which is connected to the through hole 28 of the receiving section 20.
A spring 31 is provided at a suitable position on the lower side of the rotary disk 20 on the rotation locus of the rotary disk 20 in accordance with the position so as to abut against the disk 20 with a predetermined pressure.

The supply section 30 has a passage 3 communicating with the through hole 28.
2, and a pressure regulator 34 is connected to the passage 32 by a pipe 33.
A high pressure fluid source 35 is connected via.

The operation of the embodiment of the article sorting apparatus B described above will be explained.

As the rotary disk 20 rotates, the through hole 2 of the receiving portion 22 is opened.
8 and the passage 32 of the pressurized fluid supply section 30 match, the article W in the receiving section 22 is operated as follows.

That is, the article W having the concave portion Wa engaged with the receiving portion 22 is in a state where the concave portion Wa is facing upward as shown in Figure 1)-A, and in a state facing downward as shown in Figure 1)-H. It is transported depending on the posture of either.

If the bottom surface of the article W in contact with the receiving section 22 is flat as shown in Figure 1)-A, the air discharged from the through hole 28 passes through the gap between the article W and the receiving section 22. At this time, the air flow rate increases and at the same time the pressure in this area becomes lower than atmospheric pressure, and the article W passes through the upper part of the passage 32 of the supply section 30 while being sucked and pressed toward the receiving section 22. and is not affected by the pressurized fluid source 35.

On the other hand, when the recess Wa is directed downward as shown in Figure 1)-B, the air discharged from the through hole 28 is transferred to the recess W of the article W.
As the velocity energy of air with a flow velocity is converted into pressure, the article W is blown upward due to the pressure difference between the pressure acting on the bottom surface of the article W and the atmospheric pressure, causing the article W to rotate. It falls to the underside of the disk 20 and is returned again.

The shape of the concave portion Wa of the article W can be selected based on the same principle of operation as long as it is a hinge cap, a spherical shape, or a shape that does not fall from the receiving section 22 during upper transportation.

When the article W to be sorted changes, the shape of the article W,
Any one can be selected by adjusting the fluid pressure discharged from the through hole 28 of the receiving portion 22 with the regulator 34 depending on the weight.

In this embodiment, the shape of the receiving portion 22 is formed to be concave from the surface of the rotating disk 20, but if it is convex, a guide bar may be attached to match the shape of the article W, and when the article W is on the upper side, a guide bar may be attached. It goes without saying that it can be made into various shapes as long as it does not fall.

This device B has a simple and small sorting mechanism that only needs to be placed in one place.
Since the articles W are transported in a stable state in the receiving section 22, the articles W, for example, inner caps and packing inside the caps, are inspected and sorted before they are sorted and discharged into the same device by the discharge means 24. Sections can be provided.

As this inspection and sorting means, for example, the articles W sorted on the supply section 30 are placed in the posture shown in Fig. 1)-B, and then are inspected by a sensor 36 such as a phototube as shown in Fig. 6. The product W (cap) is inspected for the presence or absence of an inner cap or packing, and the non-defective caps W are removed from the discharge path 39 by operating the solenoid valve 37 to eject pressurized fluid from the air nozzle 38.

(Effects of the Invention) The reversing device of the present invention configured as described above can be applied to a pressurized transfer body or The pressure members each having elasticity and flexibility compensate for different thickness changes, and also press against the receiving member during transfer when inversion is performed to prevent the object from moving accidentally. There is no clogging caused by the accumulation of articles, allowing smooth transfer, and continuous, large-volume work can be carried out in a short period of time.

Therefore, using a single reversing device, it is possible to continuously process articles with varying thicknesses without stopping the assembly line, which greatly improves production efficiency. Because of the versatility of the device, it can be expected to reduce costs on the assembly line.

In addition, since the structure is simple and the distance to move the article for reversing is short, it can be installed in a small factory and the work space can be used effectively.

Furthermore, the sorting and reversing device of the present invention has the sorting device and the reversing device compactly formed and integrated.
It can be manufactured at low cost, and due to the synergistic effect of these devices, it can handle a wide variety of items to be sorted and reversed, and further versatility can be expected.It can be mass-produced and can be provided at a low price.

In addition, it is easy to handle, and does not require any special skills or experience on the part of experienced personnel.
Can be applied to a wide range of industrial fields.

It has special effects such as
