Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a feeding device used for automatically feeding a cylindrical body such as a tubular container, bottle, can, etc. to a filling site for automatic filling of contents. A single device can handle long and short, thick and thin cylindrical objects, and it can accurately handle cylindrical objects one by one that are arranged in advance and stored in the chute. The object of the present invention is to provide a device with a relatively simple structure that can be turned in a predetermined direction, discharged, and supplied.

Various devices of this type are already known, but none of them feeds individual cylindrical bodies in a fixed direction by employing means such as vacuum suction, electromagnetic attraction, or mechanical gripping. However, the mechanism was complicated and it was difficult to adjust it to suit the size of the cylindrical body, and the equipment was expensive, and with a simple mechanical structure, it was necessary to supply one piece at a time. Furthermore, it had the drawback of lacking reliability.

The present invention is configured as described in the claims, so that the cylindrical bodies can be supplied one by one at a predetermined timing with a relatively simple mechanism.

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

As shown in the figure, the device of the present invention includes a chute 1 fixed to a frame F, a discharge pressure 3 disposed facing the discharge port 2 thereof, a drive mechanism 4 thereof, and a discharge pressure 3 disposed in parallel with the chute 1. It is composed of a turning seat 5 and a drive mechanism 6 thereof.

The chute 1 has a floor surface 7 and a side plate 8 rising from one side of the floor surface 7. The other side plate 9, which should be opposed to the side plate 8, has a rectangular cross section and the same length as the chute 1, and is attached to the base plate 10. The adjustable screw rod 11 is configured to be able to be adjusted in position in the width direction A of the chute 1 along a long hole 12 in the floor surface 7, and reference numeral 13 indicates a knob of the screw rod 11.

The position of the side plate 9 is adjusted according to the length of the cylindrical body 14 being handled.

The chute 1 described above has a length that can accommodate a large number of cylindrical bodies 14 in parallel, and the side plates 8 and 9 in appropriate sections near the discharge port 2 are provided with cross-sections corresponding to the thickness of the cylindrical bodies 14. Shaped restraint plates 15, 16 are attached to the side plates 8, 9 through elongated holes 17, 1B and adjustment screw rods 19, 20, 21 so as to be vertically adjustable. The interval portion of height H between them is adjusted so that the cylindrical body 14 can pass through in one row.

Note that the introduction ends 15. of the restraining plates 15, 16. '16' facilitates the introduction of the cylindrical body 14 into the spaced portion of the inverted plate.

A large number of cylindrical bodies 14 are inserted into the chute 1 by any means such as manual operation.
is supplied from above, and a stopper 22 that can protrude onto the floor 1 from below is provided at an appropriate position on the floor 7 of the chute 1.

This stopper 22 is used for maintenance, adjustment, etc. of the device.
When the supply of the cylindrical body 14 is temporarily interrupted, it is made to protrude above the floor surface 7 to prevent the cylindrical body 14 from sliding down.

The discharge pressure 3 arranged facing the discharge port 2 of the chute 1 is
As shown in FIGS. 1 and 2, when in the rest position, the flat bed surface 23 parallel to the floor surface 7 of the chute 1 and the end edge of the flat bed surface 23 on the chute 1 side hang down. The flat floor surface 23 has a width W large enough to accommodate one cylindrical body 14, and the front end of the chute 1 in the length direction is left open. ing.

The exhaust pressure 3 is generated by a shaft 25 rotatably supported by the frame F.
A drive mechanism 4 consisting of swing arms 26, 27 and a drive rod 2B fixed to the
can be swung across the discharge port 2 in a direction perpendicular to the discharge port 2 of

Due to this rocking, only the cylindrical body 14 that was on the flat floor surface 23 at the discharge pressure 3 is lifted up, but the next cylindrical body 14 in the chute 1 is lifted up by the downwardly downward wall surface 23 at the discharge pressure 3. This prevents ejection and keeps it in place.

Then, as will be described later, when the lifted cylindrical body 14 is discharged to the turning seat 5 and the discharge pressure 3 decreases to return to the original position, the blockage by the wall surface 24 is released and the next cylinder Shape 14
rotates and moves onto a flat floor surface 23 with a discharge pressure of 3.

The cylindrical body 14 resting on the flat floor surface 23 is prevented from rolling out and being ejected by the hanging wall 29 of the turning seat 5 when it is at rest.

On the discharge side of the discharge pressure 3, that is, on the opposite side to the chute 1, a diverting seat 5 is arranged.

As shown in FIGS. 1 and 2, the turning seat 5 includes a concave groove portion 30 with a V-shaped cross section running in the width direction of the chute 1, and a hanging wall that hangs down from the concave groove side on the discharge pressure 3 side. 29, and when at rest, the lower bottom of the groove 30 is the floor surface 7 of the chute 1.
, are parallel to the flat floor surface 23 at a discharge pressure of 3, and the upper end edge 31 of the hanging wall 29 is positioned above the flat floor surface 29 at a discharge pressure of 3.

This turning seat 5 is operated by a drive mechanism 6, which is shown by a chain line C in FIG. Thus, the cylindrical body can swing toward the seat 35.

The cylindrical body seat 35 is disposed upward perpendicular to the discharge port 2 of the chute 1, but it can be moved in any other direction in which the turning seat 5 can swing. There are no particular limitations.

A guide 36 facing the cylindrical body seat 35 is provided on the shaft 32 side in the swing locus of the turning seat 5, and a pop-out prevention plate 37 is arranged at a position facing the guide 36.

A bracket 4 is provided between the discharge pressure 3 and the turning seat 5.
A blocking plate 45 is fixed to the turning seat 5, and its upper end 47 is located above the flat floor surface 23 of the discharge pressure 3 when stationary, preferably at the upper end edge 31 of the hanging wall 29 of the turning seat 5.
It is placed in the same position as .

The turning seat 5 is configured so that the discharge pressure 3 moves upward in the direction of the arrow,
When the cylindrical body 14 on the flat floor surface 23 passes the upper end 47 of the blocking plate 46 and the upper edge 31 of the hanging wall 29, the cylindrical body 14 that has rolled out is received by the groove 30, and then the drive mechanism 6, the cylinder 14 is rotated in the direction of the arrow with the shaft 32 as the center of rotation to the position shown by the chain line in FIG. This acts to cause the cylindrical body to slide down onto the cylindrical body receiving seat 35.

The drive mechanisms 4 and 6 are driven by a drive source (not shown), and the operation and return of the discharge pressure 3 and the diverting seat 5 are performed alternately.

When the discharge pressure 3 returns to the original position and the next cylindrical body 14 is received on the flat bed surface 23, the diverting seat 5 is being worked as described above, so the discharge seat 3 is The blocking plate 46 prevents the cylindrical body 14 from rolling out.

Note that the hanging wall 29 has an area large enough to close the flat floor end on the discharge side of the discharge pressure 3 throughout the entire rotation stroke thereof, and even excluding the deworming plate 46, the cylindrical body 14 can be prevented from rolling out.

Moreover, when the blocking plate 46 is provided, the hanging wall 29 may be omitted.

Therefore, although the hanging wall 29 is shown as a fan-shaped body in the illustrated example, it is not limited to a curved shape.

Reference numerals 38 and 39 in FIG. 1 are inclination angle adjustment parts of the chute 1, reference numeral 40 is a position adjustment part of the discharge pressure 3, and reference numerals 41 in FIG. The reference numeral 42 is a position adjustment part between the guide plate 43 that fixes the guide 36 and the frame F, and the reference numeral 44 in FIG. 3 is an adjustment part for the protrusion height of the stopper 22. be.

The device of the present invention has the structure and function as described above, and the chute is equipped with a side plate whose position can be adjusted in the width direction and a restraining plate whose height between the chute and the floor can be adjusted. Cylindrical bodies of any length, short, thick, or thin can be supplied to the discharge port in an aligned state, and as long as the discharge pressure facing the discharge port and the size of the turning seat allow, any cylindrical body of any length, short, short, or thin can be supplied to the discharge port. Even in the body, it has the effect of being able to be supplied and discharged with a single device.

The chute discharge D Ic li has a flat floor parallel to the floor of the chute and large enough to accommodate one cylindrical body, and a wall hanging down from the floor on the chute side. Since the pressure is swingable, one cylindrical body supplied to the flat bed can be reliably discharged to the turning seat, and in the process of swinging, the chute is moved on the downward wall. Since it can support the next cylindrical body inside, it has the effect of preventing the next cylindrical body from falling from the chute without deforming it, and the cylindrical body is made of a thin metal plate that is easily plastically deformed. It acts particularly effectively in discharging and supplying water without causing any deformation, and has the disadvantage that it deforms the cylindrical body during operation, as seen in the device blocker shown in Japanese Patent Publication No. 35-11662. It has the effect of completely preventing.

In addition, on the discharge side of the discharge pressure, which is large enough to accommodate one cylindrical body, there is a concave groove running in the width direction of the chute, which is large enough to accommodate one cylindrical body, and on the discharge bank side. A diverting seat is arranged such that the concave groove side is positioned above the floor surface of the exhaust pressure when the groove side is stationary, and the exhaust pressure and the diverting seat are arranged such that their operation and return are performed alternately. Since it is connected to the drive source, it has the effect of reliably turning the cylindrical bodies arranged in the chute one by one at a constant pitch in a direction different from the chute discharge port, and discharging and supplying S. be.

Moreover, the supply pitch etc. can be easily and easily determined by the operation cycle of the drive mechanism that operates alternately.Since the drive mechanism also needs to be simply oscillated, it is possible to use a actively rotated cam mechanism etc. as the drive source. In addition, the main operating parts of the supply device, such as the discharge pressure and the diverting seat, are simple mechanisms in which the cylindrical bodies are placed one by one, so the entire device is mechanically relatively simple. It also has the advantage of being free from malfunctions and making maintenance and management easier.
