2. Description of the Related Art Recently, in canned flakes such as tuna flakes, which have a relatively small capacity, the top seam band 31 and the bottom seam band 32 have different diameters as shown in FIG. As shown in the sectional view, a can is often used in which seam bands at the top and the bottom of the other can are fitted to each other so that they can be stably stacked. These cans 30 are often sold in a state of being housed in a net-shaped bag or shrink film pack as a canned stack 33 by stacking a plurality of cans, for example, 5 cans. Conventionally, the work of stacking a predetermined number of these cans and supplying them to a net bag or a shrink film pack is actually done by hand, and has not been automated yet. That is, in a canning factory, the canned goods filled with the contents and discharged from the winding device are conveyed in a dense state on a wide conveyer conveyor, and an operator located along the conveyer conveyor takes the canned goods from the conveyor and stacks them. , The next worker is filling the bag. Therefore, at least two workers are required, and the work efficiency is poor because they are all manual work.

SUMMARY OF THE INVENTION The present invention was devised in view of the above-mentioned circumstances, and can can stacking cans conveyed in a collective state on a conveyor in a predetermined number automatically. The purpose is to provide a device.

[0004]

The canning and stacking device of the present invention has a plurality of rows of canned rollover chutes for changing the canned goods conveyed in an upright state by a conveyor to the overturned state. A canned-row conveying chute that is provided to convey the canned goods flowing out from the canned-overturning chute in an overturned state, an aligning plate that is vertically movable above the middle portion of the canning-row conveying chute, and a canning row received by the aligning plate. A cylinder device that presses in a can axis direction to form a canned stack, and an intermittent carry-out device that carries out the canned stack released from the aligning plate integrally from the chute end are adopted. I was able to solve it. It is desirable that the aligning plate comprises a pair of aligning plates arranged in parallel along the axial direction of the canning row at a distance shorter than the diameter of the canning row. It is desirable to use a star wheel provided in the.

[0005]

The canned product manufactured in the canned product manufacturing process is transferred from the upright condition to the overturned condition by passing through the reversing chute provided at the end of the wide conveyor, and is transferred onto the aligning chute. It is gathered in a rod-shaped row by the guide before reaching the position. When the canned row reaches the lower position of the aligning plate, the aligning plate descends across the chute so that the canning row hits the aligning plate and is prevented from rolling and is aligned axially along the aligning plate.
In this state, the cylinder device operates to press the canning row from both sides, so that the lower seam band of the next can is securely fitted into the upper seam band of one can, and a can stack is obtained. At that time, the aligning plate is constituted by a pair of aligning plates arranged in parallel along the axial direction of the canning row at a distance shorter than the diameter of the canning row, so that the canning row is arranged so that the canning row extends from the top to the peripheral edge in the axial direction. Since the cans can be pressed at different locations, the axes of the cans can be aligned more reliably, and the cans are prevented from moving in the circumferential direction when the cylinder is pressed, so that the canning parts can be securely fitted together. it can. The can stack is cut out from the chute one by one by the intermittent rotation of the star wheel provided at the tip of the alignment chute at a predetermined timing, and is conveyed to the next step. Therefore, the canning and stacking work, which was conventionally performed manually, can be completely automatically performed.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 designates a multi-row (6 rows in the illustrated embodiment) reversing chute formed by a plurality of round bars 2 so that the canning inlet and the outlet are twisted by 90 °. A device which is provided so as to be connected to an end of a wide conveyor (not shown) to be conveyed and which is arranged in a column and receives cans conveyed in an upright state on the end of the conveyor and rolls over until it reaches the outlet end thereof. Is. Reference numeral 3 denotes an alignment chute guide provided continuously to the end of the overshoot chute 1, which is arranged in the upper half of the alignment chute 4 and receives the overturned cans from the overrun chute, and the exit end of the cans is Assemble in a line.

Numerals 5 and 6 (FIG. 2) are a pair of aligning plates which are vertically movable by a cylinder 8 from a frame 7 which is installed on an aligning chute. The aligning plates traverse the conveyor at intervals slightly narrower than the canning diameter. Are arranged in parallel so that Reference numerals 9 and 10 are guide rods for smoothly moving up and down the alignment plate. Numerals 11 and 12 are cylinder devices for pressing the cans sandwiched between the alignment plates 5 and 6 from both sides and closely stacking them as shown in FIG. The pressure pads 13 and 14 are provided. Reference numeral 15 denotes a star wheel, which is provided above the downstream end of the alignment chute 3 and serves as an intermittent unloading device for feeding out the canned stack. The pocket 16 that meshes with the canned stack 33 is arranged to reach the end of the alignment chute. The stack 33 is temporarily received and stopped, and at appropriate timing, the canned stack is dropped onto the conveyor 18 for carrying to the next bag stacking step and sent out. A pusher 19 is provided on the conveyor 18. It is to be noted that reference numerals 20 and 21 denote side guides provided on both sides of the aligning chute so as to be adjustable, and the canning row and the canning stack are regulated on both sides by the guides and roll on the chute.

The canning and stacking device of this embodiment is constructed as described above and operates as follows. The top canned stack delivered earlier is received by the star wheel 15 at the tip of the alignment chute as shown in FIG.
In this state, the fourth canned stack is located just below the alignment plates 5 and 6 in the illustrated embodiment. When the canning rows gathered in one rod-like row at the end of the aligning chute reach the lower position of the aligning plates 5 and 6, the cylinder 8 is actuated and the aligning plates 5 and 6 descend to move the peripheral edge of the canning row from above to the axis. By pressing at two points along the axial direction, the axis of each can is aligned and restrained, and in that state, the cylinders 11, 1
2 activates to press the canning row from both sides. As a result, the lower seam band of the next can can be securely fitted into the upper seam band of the can, and the can stack as shown in FIG. 3 is obtained. The canned stack thus obtained is opened by the rise of the aligning plate and rolls on the alignment chute, but the top canned stack is prevented from falling by the star wheel. , Located in line on the alignment chute,
The star wheel provided at the tip of the alignment chute intermittently rotates at a predetermined timing to cut the alignment chute from the alignment chute and drop it onto the conveyor 18,
It is conveyed to the next bagging position by the conveyor.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-mentioned embodiments and various design changes can be made.
For example, although two aligning plates are arranged in parallel in the above embodiment, only one aligning plate may be arranged on the downstream side. The cylinder device for axially pressing the canning row may be provided on only one side. Further, the intermittent transfer device is not limited to the star wheel and may be a stopper that can be operated at a predetermined timing. Further, the canned goods having different diameters at the top and the bottom are not necessarily limited to the three-piece cans having the winding portions on both sides, but also include the two-piece cans having the winding portions on only one side.
