Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for aligning and transferring containers, particularly portion packs.

In general, molded synthetic resin containers intended for easy opening, so-called potion packs, are
There is something like the one shown in the figure.

The one shown in the drawing is a so-called milk pitcher for pouring coffee milk, and it is known that a lid body 52 is sealed against a container body 51 made of synthetic resin.
A circular flange 51a for sealing the lid 52 is formed on the upper edge of the container body, and a portion of the flange 51a is formed as a beak-shaped protruding edge 51b on the spout side.

53 is the rim 51a! lc and t indicate the sealing portion, and 53' indicates the sealing portion of the protruding edge 51bVci.

A notch 54 that does not reach the lid 52 is formed on the protruding edge 51b between the seal portions 53 and 53'.

When the container A is folded upward by grasping the protruding edge 51b,
The end of the protruding edge 51b is pulled away from the main body through the notch 54, and by pulling the cover 52 upward while grasping the broken protruding edge 51b, the cover 52 is peeled off from the main body and opened. It has become.

The potion pack has a special form as described above.
b. Moreover, since the containers are light and unstable, it is extremely difficult to transport them in a uniform direction using conventional transport devices.

A first object of the present invention is to enable even the above-mentioned special containers to be transported aligned in a certain direction.

In order to achieve this object, the first invention has several V-belts stretched in a freely transportable manner at intervals that support the container flange, and roll brushes that diagonally intersect with the longitudinal direction of the V-belt are arranged in the traveling direction of the V-belt. An input hopper with a bottom consisting of several rail-like shooters arranged at intervals to support container flanges is provided for the alignment conveyor, which is mounted on an axis so as to rotate in the opposite direction to the container collar. At the starting end 1 of the aligning conveyor, a container aligning and transferring device was constructed which extended in a crosswise manner.

Furthermore, a second object of the present invention is to automatically supply all containers punched from the lidding film to an alignment conveyor.

In order to achieve this object, the second invention has several V-belts stretched in a freely transportable manner at intervals that support the container flange, and roller brushes that diagonally intersect with the longitudinal direction of the V-belt are arranged in the traveling direction of the V-belt. An input hopper with a bottom consisting of several rail-like shooters arranged at intervals to support container flanges is provided for the alignment conveyor, which is mounted on an axis so as to rotate in the opposite direction to the container collar. The alignment conveyor is provided with a container supply chute which extends in a cross-shape at the start end 1 and which receives containers punched from the lidding film, and a supply hopper connected to this container supply chute, and a supply hopper connected to the container supply chute at the start end. a packet elevator with a top chute connected to the input hopper; and a return hopper arranged below the alignment conveyor to receive containers falling from the alignment conveyor and return the containers to the supply hopper of the packet elevator. A container transfer device was constructed with the following.

Furthermore, a third object of the present invention is to prevent the containers placed in the input hopper of the alignment and transfer device from falling, and in order to achieve this object, the third invention provides a rail-like shooter and a rail-like shooter of the device. A container alignment and transfer device was constructed in which buttons were placed at regular intervals and auxiliary chutes for preventing containers from falling were provided below the buttons.

With the above configuration, the present invention has the following effects.

That is, (I) the first invention is that the bottom of the charging hopper provided for the alignment conveyor consists of several rail-shaped shooters arranged at intervals that support the container flanges, There are two types of containers: containers whose flange is supported by a chute and slide down in a correct posture, and containers whose flange is not supported and slide down in an incorrect posture.

Containers that slide down in the correct posture are connected to the V-belt of the alignment conveyor in the 11 posture, and most of the containers that slide down in the incorrect posture also have their chute intersecting with the alignment conveyor. Therefore, when the bridge is connected to the V-belt, it is twisted by the action of both, thereby correcting its posture.

If the container is still connected to the V-belt in an incorrect button position, its position is corrected by a roll brush mounted on the alignment conveyor.

Therefore, in the first invention, the loaded containers are first aligned in advance at the bottom of the input hopper, and then their posture is corrected as they are transferred to the alignment conveyor, and then the containers are secondarily corrected by a roll brush. A final correction is made, so that all the containers transferred by the alignment conveyor are aligned and transferred in the correct orientation.

(2) In the second invention, all the containers punched out from the lidding material film are received by a container supply chute, which is further conveyed by a packet elevator and thrown into a charging hopper.

Some of the containers connected to the sorting conveyor are hit by roll brushes and fall from the sorting conveyor, but since there is a return hopper installed below the sorting conveyor, this is the packet elevator. After that, it is put into the input hopper again.

Therefore, the second invention has the effect that all the punched containers can be automatically supplied to the alignment conveyor without exception.

GI [) The third invention is provided with an auxiliary chute for preventing containers from falling below the rail-like shooters, so that containers that fall from between the rail-like shooters at tFL can fall out of the device. It has a soothing effect.

The embodiments shown in the drawings will be described below.

FIG. 1 is a schematic plan view showing the overall layout of the apparatus of the present invention, FIG. 2 is a schematic side view of the same, and FIG. 3 is a schematic side view of the same as seen from a different direction.

Reference numeral 1 designates an attached chute installed below the cutting machine (not shown). The container punched from the lidding film is received by this attached chute, and is transferred from the connecting chute 2 to the supply hopper 4 of the packet elevator 3. Ru.

The containers transferred to the supply hopper 4 are lifted up by the packet elevator 3, thrown into the input hopper 6 from the chute 5 at the top thereof, arranged by a jut turf installed at the bottom thereof, and sent to the alignment conveyor 8 below. It will be done.

Each group of containers arranged on the ju-turf is arranged by roll brushes 9 and 10 arranged on the arrangement conveyor 8, and the containers falling from the arrangement conveyor 8 are received by a return hopper 11VC arranged below the arrangement conveyor 8. The packets are then returned to the supply hopper 4 of the packet elevator 3 via the shoe 12, and then returned to the alignment conveyor 8 via the packet conveyor 3 to undergo alignment work again.

The containers thus aligned are discharged in a desired direction by a curved belt conveyor 13, for example.

Containers are transferred in the manner described above, and to explain their respective configurations in detail according to the order of transfer, the packet elevator 3 is shown in Figure 4 A, C, and C. Obviously, L-shaped packet 14 is 1
An endless belt made up of a plurality of links 15 is stretched between the wheels 16 and 17, and a tunnel-shaped cover 18 is attached only to the feed side of the belt.
is provided.

In the illustrated embodiment, the supply hopper 4 is omitted, and the top chute 5 is partially illustrated.

Among them, 3' indicates the middle 7 frames.

The packet elevator 3 constructed as described above lifts containers by moving the packets and by having the tunnel-shaped cover 18.

The input hopper 6 for receiving the containers dropped from the top chute 5 of the second packet elevator 3 is shown in Fig. 5.6.7, and has tapered slopes 19 and 19 on both sides, and is in an open state. The lower sole 20 is configured to slope downward.

Rail-shaped jut turfs are attached to the lower bottom 20 of the holder 20 with buttons spaced at regular intervals via attachment fittings 21.

22 indicates the hopper outlet. The illustrated jut turf extends further from the bottom 20 and projects at a position 1 where it intersects the V-belt of the alignment conveyor 8.

This state is shown in FIG. 8, where the alignment conveyor 8
The V-belts 23 are rotated by the pulley 24 of the driven shaft 25, and each of the V-belts 23 and the ju-turf overlap at the top and bottom at point a.

The container that fell into the input hopper 6 is A.

Three forms, B and C, settle down and flow between the rails.

All three types touch the surface of the V-belt after the shooter leaves, and C takes on the 1\E form, while A and B fall over and take on the E-like form, and are conveyed by the V-belt.

This adjustment is quite delicate and involves adjusting the slope, drop, angle, etc.

In practice, it is optimal that the intersection angle between the ju-turf and the alignment conveyor 8 is 18°±2°.

Also, the inclination angle of the juturf is preferably 30° to 45°.

In any case, when a container that slides on the ju-turf falls onto the alignment conveyor 8, its direction of travel changes, so it hits the belt of the alignment conveyor 8 and is twisted, correcting its posture. If the containers are arranged in a straight line, the above-mentioned twisting motion will not be applied to the container and its posture will not be corrected.

Below the input hopper 6, as shown by the imaginary line in FIG. 5, an auxiliary chute 26 for preventing fall is attached along the guide rail 7.

Next, the alignment conveyor 8 will be explained based on FIGS. 9.10.11 and 12.

The V-belt 23 of the alignment conveyor 8 mentioned above is connected to the pulley 2
4.26. :1!7.28, and is rotated in the direction of the arrow in FIG. 10 by driving the pulley 27 from the motor 29.

At the front of the frame 30 is a rail 31 and a round liner 32.
It is fixed with a bolt 33 through the V of the rail 31.
The V-belt 23 is guided by the groove 31a.

As described above, the V-belt 23 is connected to the rail 31 (shirt) 34.
The roller brushes 9 and 10 are guided in a straight line by a ring 35 (not shown), and roll brushes 9 and 10 are arranged diagonally across the direction of movement.

Each brush 9, 10 is driven by each motor 36 via a gear.

The direction of rotation of the brush is opposite to the direction of rotation of the alignment conveyor, and the direction of rotation of the brush is 600~
700.

The brush is elastic enough not to damage the container, so
The container may bounce off the belt and escape.

Therefore, it is preferable to have two brushes as shown in the figure.

Among them, the conveyance speed of the alignment conveyor is set to 11.9 to 14.3.
m/mar, the rotation speed of the brush is 120~2
It has been experimentally demonstrated that 00 rpm is sufficient.

The containers sorted by this roll brush 9.10 are
As shown in the figure, the flanges are supported by a V-belt 23, suspended, aligned, and transported.

Next, the curved belt conveyor 13 has an artificial side bracket 37 and an outlet side bracket 3, as shown in FIG. 1 and FIG.
A curved guide rail 39 is attached to the rail 39 via a metal fitting 40 as shown in FIG.
The container is guided and transferred, and the container is transferred by a fall belt 41 disposed below the guide rail 39.

In Figure 16, the right half shows the population side, and the left half shows the exit side.

In any case, the arrangement and transfer device of the present invention arranges the containers in advance in the chute of the input hopper, and
By arranging the extension part of the container and the starting end of the alignment conveyor so as to overlap each other in a crosswise manner, the traveling direction of each container is forcibly changed and a twisting action is given to the container. , the posture of each container is first corrected, and a roll brush is used to secondarily correct the posture of each container so that they are aligned in a certain direction. Containers that are not aligned are sent to the return hopper and packet elevator. Since the containers are returned to the input hopper using - and subjected to the arranging operation again, the containers are arranged without 〈1〉.
