Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container transfer device, and more particularly to a container transfer device that sequentially transfers containers, one by one, in a state of being overturned, through a plurality of parallel container transfer paths.

Regarding this type of device, the present applicant applied for
Since this device has already been proposed in No. 53861 (Japanese Utility Model Publication No. 58-158023), this device will first be explained based on FIGS. 3 and 4. In the figure, 1 is a hopper that stores a large number of containers A, and 2 is this hopper 1.
This is a container transfer device installed at an angle at the bottom of the container. This container transfer device 2 has shafts 3, 4, and 5 rotatably supported at the upper and lower ends, pulleys 6, 7, and 8 attached to each shaft, and a belt stretched between each pulley 6, 7, and 8. 9, and container pushing members 10 attached to each belt 9 at predetermined intervals (see FIG. 4). In addition, each of the above belts 9
There are guides 11 on both sides of the container A for guiding both sides of the outer surface of the container A.
are arranged, and a container transfer path 12 is formed between each pair of guides 11. Therefore, the container A accommodated in the hopper 1 falls due to its own weight and enters the container transfer path 12, and each container pushing member 1
0 and is transported upward along the guide 11.

Reference numerals 14 and 15 are partition members provided on the lowermost end of the hopper 1, that is, on the upstream base of the container transfer device 2. A pair of partition members 14 and 15 are provided on both sides of each container transfer path 12, and by relatively swinging these two members in the direction of movement of the container A, containers falling from the hopper 1 above can be moved. Even if A is oriented sideways with respect to the traveling direction, it can be reliably dropped into each transfer path 12.

Here, the configuration of the partition members 14 and 15 will be explained in detail. 16 and 17 are a pair of support shafts arranged in parallel above the upstream pulley 6, and one support shaft 16 of each pair of partition members 14 and 15 is
The other partition member 15 is supported at its upper part by the other support shaft 17, and each partition member 14,
15 is configured to be swingable about respective support shafts 16 and 17 as fulcrums. Each of these partition members 1
Guide surfaces 14a, 15a are formed on the upper surfaces 14a, 15a of 4, 15, and are inclined backward with respect to the plane on which the container A is transferred. It's growing. On the other hand, the back surfaces 14b and 15b of each partition member 14 and 15
A cam shaft 18 is disposed on the side in parallel with the support shafts 16, 17, and cams 19,
20 is fixed. And these cams 1
9 and 20 are fixed to the cam shaft 18 such that the cam 19 corresponding to one partition member 14 and the cam 20 corresponding to the other partition member 15 are eccentric in opposite directions. Therefore, as the cam shaft 18 rotates, one cam 19 and the other cam 20 alternately protrude, and correspondingly, each pair of partition members 14, 15 alternately swings forward in the advancing direction. If the falling container A is horizontal, it is pushed by the guide surfaces 14a, 15a of the partition member and is displaced in either the left or right direction, and is dropped into the container transfer path 12 in the traveling direction. In addition, each partition member 1
The lower tip portions 14c and 15c of the guides 4 and 15 are cut off, and a substantially triangular raised portion 11a is provided on the guide 11 at a position opposite to the cut portions 14c and 15c. The purpose of these raised portions 11a is to prevent the container A from being caught between the tips of the swinging partition members 14 and 15 and the guide 11. Therefore, the shape may be any shape as long as it can prevent the container A from being caught in accordance with the shape of the partition members 14 and 15. Further, the guide 11 is provided with a larger raised part 11b on the downstream side of the raised part 11a, and containers A that have not entered the container transfer path 12 even by the action of the partition members 14 and 15 are moved through this raised part. By climbing onto the portion 11b, the object falls into the path 12.

Further, as shown in FIG. 3, an impeller 13 is placed above the hopper 1 and faces the top surface of the container transfer device 2.
is arranged so that containers that are piled up on top of containers A to be transferred by this container transfer device 2 can be knocked down into the hopper 1 by the rotation of the impeller 13.

At the upper end of the container transfer device 2, a chute (not shown) inclined slightly diagonally downward from the vertical direction is connected to guide the transferred containers downward. The containers falling through this chute are a mixture of upright and inverted containers, so below the chute, the inverted containers are inverted and all the containers are placed in an upright position. In order to align the containers, a conventional container alignment device is provided. Therefore, the container A supplied from the hopper 1 is
Before reaching each container transfer path 12, each partition member 1
Container A that falls into the gap between the partition members 14 and 15 on both sides of each transfer route 12 also falls into the gap between the partition members 14 and 15 on both sides of each transfer path 12.
15 can be swung relative to each other so that its orientation can be changed and entered into the container transfer path 12 between each guide 11. However, as described above, since the partition member guide surfaces 14a, 15a only make a uniform pushing movement using the support shafts 16, 17 as fulcrums, the containers lying on the guide surfaces 14a, 15a are varied. Since it is not possible to apply various biasing forces, it has been difficult to sort through a group of randomly stacked containers and evenly distribute and separate them one by one. Therefore, the processing efficiency of the subsequent containers 9 is reduced, resulting in a so-called blank state in which many container pushing members 10 installed in the transfer path 12 have a large number of empty spaces, and this is a limit to increasing the transfer efficiency of the containers A. I was getting used to it.

The present invention was devised in view of the above-mentioned drawbacks, and includes a guide member that guides the sides of the containers to be transferred, and a plurality of container transfer paths separated by the guide member, and which allows a group of containers to be transferred. In a container transfer device that receives containers into each of these container transfer paths and transfers them in a plurality of rows, a vertically swinging member consisting of a pair of partition plates that are placed along the guide member and whose overlapping portions are connected by pins is pivoted at each other end. One of the two pivot points of either one of the partition plates is connected to a long hole, and the other partition plate is provided with a swinging mechanism that swings it up and down. The swinging mechanism is configured as a swinging mechanism that alternately swings up and down the respective vertical swinging members along each of the plurality of guide members, and according to the present invention having such a configuration, each By alternately bending and stretching a plurality of swinging members each consisting of a pair of connecting partition plates that divide the container transfer path, each container is scrambled and overlapped laterally or diagonally on each container transfer path. It is possible to reliably catch the partition plate when it bends during the bending/stretching movement and distribute it laterally when it extends, effectively eliminating the scrambled state of the container group and dropping it into each transfer path,
Container transfer efficiency can be increased.

Hereinafter, based on the embodiment shown in FIGS. 1 and 2, the same or corresponding parts as those described above will be denoted by the same reference numerals, and the explanation will focus on differences in structure. FIG. 1 shows a first embodiment of the present invention, in which reference numeral 21 denotes a substantially arch-shaped first partition plate, one end of which is attached to a support shaft 22 horizontally arranged in front of the front wall 1a of the hopper. It is attached by loosely fitting into the elongated hole 21a. Reference numeral 23 denotes a substantially fan-shaped second partition plate, one end of which is pivotally supported by a support shaft 16 attached to the back side of the belt 9 so as to pass orthogonally therethrough, and the other end of the second partition plate 21 is connected to the first partition plate 21.
A link is formed by overlapping the other end and being pin-coupled via a pin 24. Furthermore, this second partition plate 23 has a protrusion 23a extending downward from its pivot point.
An eccentric cam 19 is engaged with the eccentric cam 1.
9 rotates the second partition plate 23 to its support shaft 1.
6 as the center, thereby causing the link with the first partition plate 21 to bend and extend. At this time, the first partition plate 21 is reciprocated along the support shaft 22 through the elongated hole 21a. Note that the eccentric cam 19 has the second
It is attached to a camshaft 18 arranged parallel to the support shaft 16 of the partition plate 23.

The links of the first and second partition plates 21 and 23 are installed along the sides of each guide 11, and are opposite to each other along with the links of the partition plates 21 and 23 of the other guides 11 that face each other across the transfer path 12. The partition plates protrude onto the container transfer path 12 by relatively bending and stretching in the direction, and variously change the intervening angle θ between the upper edges of each of the partition plates 21 and 23. By reliably catching the container when it is bent and distributing it laterally when it is extended, it is possible to more reliably sort the container group.

Therefore, in FIG. 1, the first and second partition plates 21 and 23 at the lowest position indicated by the two-dot chain line move in the following manner as the eccentric cam 19 rotates clockwise. That is, the first partition plate 21 has its long holes 2
1a, it rotates counterclockwise while sliding on its support shaft 22, and changes the angle θ between the upper edges of each partition plate 21, 22 from angle θ ₀ to 180°.
In other words, the rotation of the eccentric cam 19 causes the first and second
Since the partition plates 21 and 23 bend and stretch in the vertical direction between the state shown by the two-dot chain line and the state shown by the solid line shown in the same figure, the containers A can be reliably separated one by one without getting stuck between the partition plates 21 and 23. It is distributed within each space defined by each container pushing member 10 of the container transfer path 12, and the transfer efficiency can be greatly improved.

FIG. 2 shows another embodiment of the present invention, which differs from the above embodiment in that the mounting positions of the first partition plate 21 and the second partition plate are interchanged. That is, the first partition plate 21 has a fan shape, and a long hole 21a is bored in the center of the first partition plate 21.
is loosely fitted onto a support shaft 22 extending through the guide member 11. The second partition plate 23 has a fan shape smaller than the first partition plate 21, and its center portion is pivotally supported on the support shaft 16 in front of the hopper front wall 1a, and its corner portion overlaps with the first partition plate 21. and are pin-coupled via pins 24, forming a link. Further, in front of the front wall 1a of the hopper, a camshaft 18 is installed slightly below the front of the support shaft 16.
The eccentric cam 19 fixed thereto is connected to the second partition plate 2.
It engages with the side edge of 3. Therefore, camshaft 1
8 rotates clockwise, the second partition plate 23 begins to swing counterclockwise, and the first partition plate 21 swings clockwise and moves downstream along its support shaft 22. Displace to the side. After each partition plate 21, 23 reaches the state shown by the solid line, it returns to the original state shown by the two-dot chain line via the reverse path. It is clear that the same effects as in the above embodiment can be achieved by performing bending and stretching movements between these states.

In addition, in each of the above embodiments, the hopper front wall 1a
Front wall 1 so that the partition plate located on the side can swing
Needless to say, a notch is provided in a.

In addition to the above-mentioned embodiment, a hole into which a pin 24 can be loosely fitted is provided in one of the pin-coupled partition plates 21 and 23, and the other end is pivoted on each support shaft 16 and 22. You can do it like this.

Furthermore, the same effect can be obtained even if the partition plates 21 and 23 are not sector-shaped but long and narrow rod-shaped plates. In short, each partition plate 2 on which container A is placed
It is sufficient that the angle θ between the partitions 1 and 23 is changed, and one of the two pivot points of one of the partition plates is connected to a long hole, and the other partition plate is connected with this. It is sufficient that the connecting partition plate is provided with a swinging mechanism for swinging, and it goes without saying that the swinging mechanism may also be formed by means other than eccentric cams.

As described above, according to the present invention, by alternately bending and stretching a plurality of swinging members each consisting of a pair of connecting partition plates that divide each container transfer path, each container transfer path is scrambled. The containers that overlap laterally or diagonally are reliably caught during the bending of the partition plate during the bending and stretching movement, and are distributed laterally during the extension, effectively eliminating the scrambled state of the container groups and moving them into each transfer path. can be dropped into the container, increasing container transfer efficiency.
