JPS604089B2 - Front and back sorting device for bottomed cylindrical members - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sorting device for sorting the front and back sides of a bottomed cylindrical member such as a cap.

Conventionally, various configurations of sorting devices have been proposed for sorting the front and back sides of bottomed cylindrical members such as caps, but conventional sorting devices generally require a drive source and an actuator operated by the drive source. However, the configuration was complicated and expensive.

According to the present invention, when air is injected toward the front surface of the bottomed cylindrical member and when air is injected toward the back surface, the air pressure is received by the side wall portion of the bottomed cylindrical member. This method was developed based on the fact that the pressing force acting on the bottomed cylindrical part changes greatly depending on whether it is used or not, and it is an inexpensive sorting method that basically does not require a drive source or actuating part to sort out the bottomed cylindrical part. It provides equipment.

The present invention will be described below with reference to the illustrated embodiment. In FIG.
is fixed, and a fixed shaft 3 is attached perpendicularly to the inclined part of this placket 2.

A rotating member 4 is rotatably supported around the fixed shaft 3, and the rotating member 4 is moved by a motor 7 provided on the bracket 2 via gears 5 and 6. The rotating member 4 is equipped with a ring-shaped rotating table 8 that rotates integrally with the rotating member 4.
As shown in the figure, a scooping plate 9 of the cap C along the radial direction and a scooping plate 10 along the axial direction are attached at equal intervals. On the other hand, the bracket 2 has a conical support village 1.
a cylindrical case 1 that covers the rotary table 8 through a cylindrical case 1;
2 is attached so that the cap C can be accommodated within this case 12. The caps C housed in the case 12 are stacked randomly under the case 12, which is tilted by gravity. , is engaged with the scooping plate 9 of the rotary table 8 and transported upward in the circumferential direction together with it, and when the scooping plate 9 rotates at least 90 degrees or more from the lowest point position, the longitudinal direction of the scooping plate 9 , and is transferred to the front and back separation section of the cap, which will be described in detail later.

The thickness of the scooping plate 9 is set to approximately the thickness of the cap C, and the other scooping plate 10 breaks the cap placed on the lower inner peripheral surface of the case 12 and places it on the rotary table 8. It functions to move the A fixed support plate 20 is fixed to the upper end of the fixed shaft 3 that extends diagonally upward through the rattle of the rotary member 4, and a fixed support plate 20 is fixed to the upper end of the fixed shaft 3 that extends diagonally upward with respect to the axis of the fixed shaft 3. A tilted second fixed shaft 21 is attached. A second rotating member 22 is rotatably supported on this fixed shaft 21, and a second rotating table 23 is fixed to this second rotating member 22. The second rotating member 22 is
A bevel gear 24 is fixed to this, a bevel gear 26 is attached to the upper end of the shaft 25 rotatably supported on the fixed support plate 20 and meshed with the bevel gear 24, a gear 27 is attached to the lower end of the shaft 25, and a gear 27 is meshed with this. The second rotary table 23 is moved in conjunction with the rotary member 4 through the gear 28, and is moved by the motor 7 through the gears 5 and 6 to move the second rotary table 23 into the first position.
The rotary table 8 can be rotated at a speed further than that of the rotary table 8. The rotary member 4 has a cylindrical concave portion 4 recessed into the surface of the surrounding rotary table 8 in its shaft portion.
a, and the outer peripheral portion of the fixed support plate 20 is also arranged within the concave portion 4a.

The second rotary table 23, which is disposed obliquely with respect to the rotating member 4 and the fixed support member 20, has only a portion of its upper end located within the recessed portion 4a, that is, below the surface of the first rotary table 8. It is set as follows. Furthermore, a cylindrical fall prevention member 29 is attached to the outer circumference of the fixed support plate 20 to prevent the cap C on the first rotary table 8 from falling into the recessed portion 4a. The upper end portion is cut diagonally along the surface of the second rotary table 23, and a semicircular shape is provided directly above the portion to transfer the cap on the first rotary table 8 onto the second rotary table 23. A gangboard 30 is installed (see Figure 3). Therefore, the cap C, which is moved upward by abutting against the scooping plate 9 due to the rotation of the rotary table 8 mentioned above, falls along the scooping plate 9 due to its own weight, and is rotated through the second rotation via the spanning plate 30. It will be delivered on the table 23. Next, a support plate 31 fixed to the second fixed shaft 21 is disposed above the shaft of the second rotary table 23, and as shown in FIGS. A guide 33 is provided at the tip of three support arms 32 attached across the section.

As shown in FIG. 3, this guide 33 receives the cap C that slides and falls on the spanning board 30, and as the second rotary table 23 rotates, the cap C is moved clockwise along the guide 33. It is now possible to guide you. Further, a guide 34 is attached to the fixed support frame 20 along the right outer periphery of the second rotary table 34, and the cap C, which has been conveyed clockwise along the guide 33, is separated from the guide 33 due to its own weight and vertically downward. When the cap is moved, the guide 34 receives the cap so that it can be continuously transported in a clockwise direction. Further, a chute 35 is connected to the lowermost part of the second rotary table 23 for receiving the cap C transferred along the upper guide 34 and supplying it to the next capping machine or the like.

At the entrance of this chute 35, a second rotary table 23 is provided.
A baffle plate 36 is provided between the surface of the chute 35 and the surface of the chute 35 so that there is a gap that allows only one cap C to pass through. We are making it possible to join together. Note that the baffle plate 36 is attached to the support plate 31 via a support arm 37. However, the caps C supplied to the chute 35 have not yet been sorted on their front and back sides, and these caps are sorted in the sorting section provided in the upper curved part 36a of the chute 35, and only caps in one state are selected. The cap can then be moved inside the chute 35, and the cap in the other state can be blown off from inside the chute 35 onto the first rotary table 8 outside.

FIG. 4 is a sectional view of the sorting section. The chute 35 is equipped with upper and lower guide plates 37 that support the upper and lower surfaces of the cap C, and a pair of side plates 38 that support both sides. As shown in FIG. 3, a notch 39 through which the cap C can pass is formed in a part of the side plate 38 above the curved part 35a, and along the longitudinal direction of each of the upper and lower guide plates 37. , a through hole 40 having a width narrower than the diameter of the cap C is bored.

The upper guide plate 37 has a through hole 40 and a curved portion 3.
Nozzle 41 that injects air toward the lower side plate 38 of 5a
In addition, the lower guide plate 37 has a through hole 40 therein.
A nozzle 42 is provided for injecting air from the air toward the notch 39 located above the curved portion 35a. These pair of upper and lower nozzles 41 and 42 are arranged so that air can be sprayed onto the same cap C at the same time. Furthermore, a pair of nozzles 43 and 44 are provided on the downstream side of these pair of nozzles 41 and 42 in a substantially similar relationship. In the above configuration, as shown in FIG. 4a, when the bottomed cylindrical cap C is supplied in the form of hair to the chute 35 and reaches the sorting section, a pair of upper and lower nozzles 41, 4 are attached to the cap C.
Air is sprayed in the opposite direction from the nozzle 41 at the same time, but when the cap is in the reverse position, the air from the nozzle 41 is effectively received by the side wall portion around the cap. becomes biased toward the lower side plate 38 of the
The driver will continue to move inside the chute 35 while being guided by the user.

On the other hand, as shown in FIG. 4M, when the cap C reaches the sorting section in an open state, it effectively receives air from the nozzle 42 below the cap, so that the weight of the cap and the air from the nozzle above are absorbed. It is moved toward the notch 39 against the air pressure from 41, passes through this notch 39, and is dropped onto the rotary table 8.

Although not shown, a sliding plate is disposed between the notch 39 and the left side portion of the second rotary table 23 and the fall prevention member 29, so that the cap and baffle plate discharged from the notch 39 can be removed. 36 obstructs the supply to the chute 35, and along the baffle plate 36 the second rotary table 23
Care is taken so that the cap discharged to the outside falls smoothly onto the first rotary table 8.

Further, in the above embodiment, a pair of nozzles 43 and 44 are further provided downstream of the pair of nozzles 41 and 42 to improve the reliability of sorting.
4 may be omitted. Furthermore, as can be understood from the above embodiments, since the cap can be moved using its own weight, the present invention basically does not require a conveying means for the cap, but for example, a net-like conveyor, etc. It is also possible to transport the caps using the method, and it is clear that not only caps but also bottomed cylindrical parts can be sorted in the same manner.

As described above, since the present invention basically requires only the provision of a pair of /zuru, it is possible to obtain the effect that the configuration can be made very simple.
