Next, the bridge breaker swings to move the article and prevent the occurrence of a bridge.

At the exit side of the aisle, a pushing device and an intermittent pushing device work together to open and close the gate of the aisle to control the number of articles sent out in a zigzag arrangement, and the turning plate operates to direct or deflect the movement of the articles. A staggered arrangement is realized by causing a half-pitch shift between the front and rear article rows.

[Embodiment] A description will be given below of a drawing showing an embodiment in which the details of the present invention are applied to a camparizer for which a cylindrical can is an object.

In FIG. 1, reference numeral 1 is a palletizer article aligning device, and the palletizer article aligning device 1 is a traveling conveyor 2
A separator device 3, a bridge breaker 4, a guide frame 5, an intermittent feeding device 6, a pushing device 7, and a turning plate device 8 are provided immediately above the conveyor 2 along the traveling direction of the conveyor 2. Each of the plurality of guide frames 5 is constituted by a set of two frame bars 11 and 12, and a plurality of the frame bars 11 and 12 are provided in parallel to each other. 13
To form. The passages 13 have a width that allows the cylindrical cans 14 to pass through one by one.

The separator device 3 is located in front of the entrance side of the passage 13, and as shown in FIG. 2, the head 15 located at the tip and the guide members 16 and 17 that project obliquely on both sides of the head 15 are arm members. Mounted on 18. Arm material 18 is a support frame 21
It is mounted so that its horizontal and vertical positions can be adjusted. The extension angle of the guide members 16 and 17 is the turnbuckle 22
Is adjustable by.

In this separator device 3, when the cylindrical cans 14 are coarsely and densely distributed to the conveyor 2, the head 15 divides the solidification of the cylindrical cans, and the guide members 16 and 17 guide the cylindrical cans. The distribution is evenly distributed.

The bridge breaker 4 comprises a plurality of swing arms 23. The swing arms 23 are swingably attached near the tip ends of the frame bars 11 and 12 of the guide frame 5, respectively.
Further, all swing arms 23 are swingably connected to a common drive bar 24. The drive bar 24 is cranked via the connecting rod 25.
Therefore, the drive bar 24 reciprocates laterally (in the direction of arrow 9) by the rotation of the crank 26, which causes the swing arm 23 to swing and is sent to the conveyor 2. The cylinder can 14 is brought into contact with the cylinder can 14 that has come and the cylinder can 14 is moved to prevent the occurrence of a bridge.

The intermittent pushing device 6 is the most lateral passage of the plurality of passages 13.
The intermittent feed piece 27 is located on the outlet side of 13a to open and close the passage 13a. The intermittent feed piece 27 can rotate in a plane parallel to the surface of the conveyor 2. As shown in FIG. 3, the intermittent feed piece 27
Alternates between two constraining surfaces 28 in which a virtual cylindrical surface is cut out within a rotation angle range of 90 ° and two non-constraining surfaces 29 in which the virtual cylindrical surface remains as is in a rotation angle range of 90 °. It is provided. The intermittent feed piece 27 restrains the cylindrical can 14 when the cylindrical can 14 is in contact with the constraining surface 28, and when the intermittent feed piece 27 rotates in this state, the constraining surface 28 pushes the cylindrical can 14 to pass through the passage 13a. Therefore, at this time, the passage 13a is opened by the intermittent feed piece 27.

On the other hand, when the cylindrical can 14 is in contact with the unconstrained surface 29,
The non-restraining surface 29 and the cylindrical can 14 are only in sliding contact with each other and do not feed the cylindrical can 14, and the cylindrical can 14 does not pass through the passage 13a. At this time, the passage 13a is closed by the intermittent feed piece 27. Therefore, the intermittent feed piece 27 feeds out two cylindrical cans in one rotation.

As shown in FIGS. 3 and 4, in the pushing device 7, the feeding piece 28 is located on the outlet side of the remaining passage 13b of the plurality of passages 13 excluding the passage 13a to open and close the passage 13b.

The feed piece 30 is rotatable in a plane parallel to the surface of the conveyor 2. The feed piece 30 has four constraining surfaces 31 in which a virtual cylindrical surface is cut out within a range of a rotation angle of 90 °. The feed piece 30 restrains the cylindrical can 14 when the constraining surface 31 is in contact with the constraining surface 31, and when the feed piece 30 rotates in this state, the constraining surface 31 pushes the cylindrical can 14 to pass through the passage 13b. Therefore, at this time, the passage 13b is opened by the feed piece 30. Therefore, the feed piece 30 also feeds out four cylindrical cans in one rotation.

Turning plate device 8 is shown in FIG. 3, FIG. 4, FIG.
As shown in FIGS. 6 and 7, it is located on the outlet side of the passage 13b and on the downstream side of the feed piece 30. The turning plate device 8 is for defining the lateral feed position (course) of the cylindrical can sent from the feed piece 30.

The turning plate device 8 has a turning plate 32, which is attached to the rocking shaft 33 and is positioned within a range of about 40 ° in a plane parallel to the surface of the conveyor 2 as shown by the solid line in FIG. And a position indicated by an imaginary line. When the turning plate 32 is in the position shown by the solid line, it contacts the cylindrical can 14 to deflect the cylindrical can 14 to the course shown by the arrow 34, and when the turning plate 32 is in the position shown by the phantom line, Abut on a cylindrical can
Move 14 directly to the course indicated by arrow 35.

A lever 36 is attached to each of the swing shafts 33, the lever 36 is connected to another lever 38 via a common connecting rod 37, and the other lever 38 is connected via another connecting rod 41. crank
It is connected to 42. The rotation of the crank 42 causes the swing shaft 33 to swing back and forth in the left-right direction, and the turning plate 33
32 swings. The rotation of the crank 42 is synchronized with the rotation of the intermittent feeding piece 27 of the intermittent pushing device 6 and the feeding piece 30 of the pushing device 7 by the gear train 43 and the shaft 44.

The operation of the palletizer article aligning apparatus configured as described above is as follows.

Multiple cylinder cans 14 supplied to the palletizer article aligner
Are placed on the conveyor 2 and sent.

When it comes to the place where the separator device 3 is provided, the solidification of the cylindrical can 14 is divided by the head 15 and the guide members 16, 17
Guided by and distributed to the bridge breaker 4 after being evenly distributed.

In the bridge breaker 4, the movable bar 24 linearly reciprocates due to the rotation of the crank 26, whereby the swing arm 23 swings to move the cylindrical can 14 and prevent the occurrence of a bridge.
In this way, the cylindrical cans 14 smoothly pass between the swinging arms 23 one by one, enter the passages 13a and 13b, and reach the outlet sides of the passages 13a and 13b. At the exit side of the passages 13a and 13b, among the cylindrical cans 14 that are sequentially sent, the cylindrical can that is sent first and the cylindrical can that is sent next are treated differently alternately. That is, first, when all the passages 13b are closed by the feed piece 30, the restraining surface 31 of the feed piece 30 is in a position to receive the first cylindrical can 14a. Similarly, when the passage 13a is closed by the intermittent feed piece 27, the restraining surface of the intermittent feed piece 27 is ready to receive the first cylindrical can 14a. When all the constraining surfaces 31 and 28 receive the initial cylindrical can 14a, all the feed pieces 30 and the intermittent feeding pieces 27 rotate 90 ° at the same time, and all the initial cylindrical cans 14a are fed out at the same time. At this time, turning plate 32
Is in a position indicated by an imaginary line, and does not contact the sent-out first cylindrical can 14a, and therefore the first cylindrical can 14a moves linearly in a direction indicated by an arrow 35.

Next, when the constraining surface 31 of all the feed pieces 30 receives the next cylindrical can 14b, all the feed pieces 30 simultaneously rotate 90 ° to send out the next cylindrical can 14b. In the intermittent feed piece 27, the non-restraining surface 29 comes into contact with the cylindrical can 14b and idles, so that the cylindrical can 14b is not fed. Therefore, the number of the next cylindrical cans 14b to be delivered is one less than that of the first cylindrical can 14a. When the next cylindrical can 14b is sent out, the turning plate 32 is in the deflection position shown by the solid line, and comes into contact with the sent out cylindrical can 14b to deflect the cylindrical can 14b.
The lateral position is shifted by a half pitch and set to the position indicated by arrow 34.

Such sending out is repeated, and eventually all the cylinder cans are
14 are arranged in a staggered pattern as shown in FIG.

[Effects of the Invention] In the palletizer article aligning device of the present invention, a magnet is not used on the exit side of the passage, and the cylinder can is mechanically restrained to control the position, so that the cylinder can is made of a non-magnetic material such as aluminum. Even when configured, it can be handled reliably.
