The product 10 assembled at the assembly station is placed on the stand 11.
This is a roller conveyor that is mounted on a roller conveyor and conveyed along the conveyance path shown in FIG.

Attached to the stand 11 is a model-specific card (recording medium) 12 formed by encoding reflective marks in bright and dark areas according to the model (size) of the product. The product model identification means 1 is
As shown in FIG. 2, there is a fixing jig 14 for fixing the tip of the glass fiber 13 so as to face the reflective mark of the model-specific card 12 at the same pitch, and a fixing jig 14 installed at the rear end of each of the glass fibers 13. A beam switch 15 is installed, and the code recorded on the model identification card 12 is read to identify three types of product models (sizes). Magazine 2a! 2b and 2c have two types of cardboard 18a,
18b and 18c are supplied and stored in a folded and stacked state,
Phototubes 20a, 20b, 20c each detect the position of the top end of the cardboard 18a, 18b, 18c, and each cardboard 18a, 18b, 18c is raised until the output from the phototube 20a, 20b, 20c changes from 0N to 0FF. lifters 19a, 19b, and 19c, and are configured such that the top ends of the cardboard boxes 18a, 18b, and 18c are always located at the positions where the phototubes 20a, 20b, and 20c are installed. - The cardboard conveying means 4 constituted by a belt conveyor includes these magazines 2a,
It is installed so that the cardboard 18 is conveyed to the cardboard erecting means 5 in parallel with the arrangement of the cardboard boxes 2b92c. Cardboard take-out means 3a, 3b, 3c are installed for taking out and transporting each cardboard 18a, 18b, 18c from each magazine 2a, 2b, 2c to the top of the cardboard transport means 4. This cardboard removal means 3a93b9
3c, a rail 21 extending from above each magazine 2a, 2b, 2c to above the cardboard transport means 4, a unit carriage 22 that moves while being guided along the rail 21, and a unit carriage 22. A sprocket 25 for suspending a chain 24 connected to the sprocket 24 and a motor 23 for rotationally driving the sprocket 25 are provided. The unit truck 22 has an air cylinder 27.
and a guide receiver 28 are installed, and this air cylinder 27
A plate 29 having at least four vacuum pads 26 attached to its lower end is attached to the output shaft, and a guide rod 30 fixed to the plate 29 is slidably fitted into the guide receiver 28.

The cardboard upright means 5 is located at the end of the cardboard conveying means 4, and is driven by a motor 32 to vertically move the cardboard upright 9 around a shaft 33.
A reversing arm 34 formed to rotate by 0 degrees is formed to position the cardboard 18 by abutting one end of the cardboard 18, and a motor 35 is driven by a signal obtained from the product model identification means 1. A positioning plate 37 is provided which is configured to move the shaft 36 by a predetermined amount in the horizontal direction based on the relationship between the pinion and the rack. The cardboard box making means 6 is a cardboard upright means 5.
Cardboard 18, which was in an upright position, fell down a little and stopped.
A bogie 42 is installed with a support 43 attached with a vacuum pad 39 that sticks to the front surface of the bogie 42 protruding upward, and
A rail (
(not shown) and a sprocket 4 connected to a motor 45.
4, a chain 46 installed on the sprocket 44 and connected to the cart 42, an inclined portion that contacts one side wall of the cardboard box 18 and rotates around the fold line to form a box shape, and a fold line W. A forming guide 40 is provided in which a guide portion is formed on a straight piece of soil with the position of The side wall of the cardboard 18 is rotated about the fold line W by the inclined portion 40 to form a box shape.

The bottom sealing means 7 is formed by folding the side flaps of the bottom of the cardboard box separated from the vacuum pad 39 and falling under its own weight with a folding member (not shown) installed there, and applying hot melt to the bottom side flaps. A push member 51 attached to the output shaft of the air cylinder 50 feeds the cardboard box, and a member (not shown) folds the front and rear flaps of the bottom.
The bottom of the box is sealed by folding it in and fixing it with adhesive. The bottom sealing means 7 is equipped with a number of phototubes (not shown) that detect the width and height of the cardboard box, and signals obtained from the phototubes are used to move the guide member that guides the cardboard box to perform various inspections. It is configured to accommodate cardboard boxes. The discharge conveyor 8 has a bottom sealing means 7
It is configured such that the cardboard box whose bottom is sealed can be discharged and transported to a position 52 where the product 10 is packed. However, when the product 10 is mounted on the stand 11 and transported on the roller conveyor 9, the stand 11
The beam switch 15 corresponding to the most advanced reflective mark on the model-specific card 12 attached to the machine turns 0N, and at the same time, the beam switch 15 corresponding to the subsequent reflective mark turns 0N,
By the combination of 0FF, the product model identification means 1 outputs a signal 16 encoded according to the model (size).

Note that there are three types of signals 16. On the other hand, the cardboard retrieval means 3a, 3b, 3c are operated and each magazine 2a,
The cardboard boxes 18a, 18b, 18c are sucked up from the magazines 2b, 2c by the vacuum pad 26, and the unit cart 22 is moved to the magazines 2a, 2b, 2c by the drive of the motor 23.
It is moved from above to above the cardboard conveying means 4 and stopped to wait.

Then, as described above, upon receiving the model-specific control signal 53 corresponding to the type of product 10, the cardboard removal means 3a, 3b, 3c
Among them, the adsorption of the vacuum tube 26 of a predetermined cardboard take-out means is selectively released, and the predetermined folded cardboard is transferred to the cardboard transport means 41/R. It is dropped and loaded. When the products 10 mounted on the stand 11 pass sequentially through the model identification means 1, the adsorption of the vacuum pad of a predetermined cardboard retrieval means is selectively released by a signal from the control device 17, and the cardboard is placed in a predetermined position. The cardboard boxes are loaded on the cardboard transport means 4 and transported in this order. At the same time, the motor 35 of the cardboard uprighting means 5 is driven based on the model number 1 control signal 54 from the control device 17, and the positioning plate 37 moves in the direction of the arrow to bend the left side of the cardboard as shown in FIG. The right end of the cardboard 18 is brought into contact and positioned so that the position of the eye w coincides with the guide portion of the forming guide 40 (the portion formed parallel to the moving direction of the cart 42). Then, when positioning is detected by a phototube (not shown), the motor 32 is driven to rotate the reversing arm 34 from horizontal to vertical, bringing the cardboard 18 into an upright position and causing it to slide down a little. Then, the vacuum pad 39 of the cardboard box forming means 6 is operated, the front wall of the cardboard box 18 is attracted, and the cart 42 is moved by the drive of the motor 45. Then, the left side wall of the cardboard box 18 is rotated clockwise around the fold line W at the tip of the inclined part of the forming guide 40, and when it reaches the guide part of the forming guide 40, a rectangular cardboard box is formed.
When the rectangular cardboard box 48 is formed in this way, the cart 42 stops and the vacuum pad 39 also releases its suction. Then, the cardboard box 48 falls down a little, the side flaps at the bottom are bent, hot melt is applied, the air cylinder 50 pushes the cardboard box 48, the front and rear flaps at the bottom are bent and glued, and the bottom sealing means 7 closes the box. Position 5 where the bottom part is sealed and the product is packed by the discharge conveyor 8
Transport up to 2. At this packing position 52, the products 10 that are transported by the roller conveyor 9 are packed in corrugated cardboard boxes that are sealed only at the bottom. Then, the upper sealing means 55 seals the soil part. In the above embodiment r, the model-specific card (recording medium) is attached to the stand 11, but it is not possible to directly attach the model card (recording medium) to the product 1.
As described above, according to the present invention, it is possible to automatically and quickly form cardboard boxes in response to randomly flowing products, and also to merge the products at the boxing position and sequentially stack the products. It has the effect of being able to be packed in a cardboard box.
