In addition, the knob portion 12 is connected to the bonding portion 18. FIG. 3 is an enlarged view showing an example of the identification symbol 21, and the one shown is a four-digit number 24 in a rectangular frame 23.
It has a configuration in which are arranged. A winding margin portion 25 for the top curl portion 10 is provided at the upper edge of the blank 2, and a folding margin portion 26 for the folding portion 11 is provided at the lower edge. The folding margin portion 26 is provided with a plurality of notches 27 for facilitating folding when forming the folding portion 11.

FIG. 4 shows an apparatus for manufacturing a body of an ice cream container using the blank 2 as described above,
30 is a supply device for the blank 2, 31 is a body forming device that forms the body of the container by winding the supplied blank 2 into a cylinder, 32 is a body forming device 31, and the body of the container is taken out for the next step. A transfer device for sending out, 33 is an upper and lower edge processing device for forming the top curl 10 on the upper edge of the blank 2 wound in a tubular shape and forming the folded portion 11 on the lower edge, and 34 is a container for taking out the completed container body. It is a take-out device. The body forming device 31 has a large number of spindles 35.
A turret 36 with a
The motor 6 is intermittently rotated in the clockwise direction by a motor (not shown). The transfer device 32 includes a transfer claw 37 that takes out the container body from the body forming device 31 and conveys it to the upper and lower edge processing device 33. The upper and lower edge processing device 33 is provided with a turret 39 on which a large number of mandrels 38 are erected, and further has a holder 40 for holding the container body when the upper edge of the blank 2 is pressed and curled in the subsequent step. A turret 41 for edge treatment is arranged. The turret 39 is rotated in the counterclockwise direction by a motor (not shown), and the upper edge processing turret 4
1 rotates intermittently in the clockwise direction. A plate (not shown) for folding the lower edge of the blank 2 inward to form the folded portion 11 is provided above the turret 39, and below and above the mandrel 38 provided on the turret 39. Plates (not shown) for curling the upper edge of the blank 2 outward to form the top curl portion 10 are provided below the edge processing turret 41, respectively.

Is provided.

In the body part manufacturing apparatus as described above, the bundle 35 of blanks 2 is set at the starting end part of the supply device 30, and the blanks 2 taken out one by one from here are inverted halfway and then formed in the body part. It is sequentially supplied to the spindle 35 of the device 31. Then, after sucking the end portion of the blank 2 onto the spindle 35, the blank 2 is rotated by the rotation of the spindle 35.
Is wound around the spindle 35. As a result, the bonding portions 17 and 18 at the left and right ends of the blank 2 are overlapped (see FIG. 5). Thus blank 2
When it is wound in a tubular shape, the turret 36 intermittently rotates and moves to another place, and heat-seals and welds the overlapping portions 17 and 18 of the blank 2 wound in a tubular shape in an overlapped state. . FIG. 5 shows a container body 45 formed by heat-sealing the blank 2 in a tubular shape as described above. The container body 45 is bonded at the lower ends of the bonded portions 17 and 18 welded as shown in the figure. The identification mark 21 provided on the bonding section 17 can be seen through the cutout section 22 of the section 18. Also,
The notches 19 and 20 overlap each other at the upper ends of the bonding portions 17 and 18, thereby forming a portion 46 having no winding margin portion 25.

Next, the container body 4 thus formed in a cylindrical shape
5 is taken out from the spindle 35 of the barrel forming device 31 by the transfer claw 37 of the transfer device 32 and is transported to the upper and lower edge processing device 33, and the container barrel 45 is transferred to the mandrel 38 standing on the turret 39. After that, the turret 39 is intermittently rotated, and the winding margin portion 25 at the upper edge of the container body 45 is curled by plates (not shown) arranged above and below, and the folding margin portion 26 at the lower edge is folded inward to form the top curl portion. 10 and the folded portion 11 are formed. By thus folding the folding margin portion 26 at the lower edge of the container body, the identification mark 21 is folded inward and is invisible from the outside. After that, the container body is transferred to the holder 40 provided on the upper edge processing turret 41, and the top curl portion 10 is formed by a plate (not shown). The container body 45 thus completed is transferred from the upper edge processing turret 41 to the container removing device 34 to be in a stacked state, and when a predetermined number of container body 45 are stacked, the container body 45 is sequentially discharged to the stacker 42. It is like this.

When manufacturing the container body 45 as described above, the identification mark 21 is read on the blank 2 so that the different container body is eliminated.
An example of the determination method will be described with reference to FIG. 6. Reference numeral 50 denotes a camera for reading the identification symbol 21, and the signal read by the camera 50 is sent to the control device 52 via the cable 51. ing. An operator can set and input an arbitrary identification symbol 53 to the control device 52. In the control device 52, the identification symbol 21 read by the camera 50 and the setting identification symbol 53 input by the operator are compared to each other. If they are different, the emission command 5
4 is output. In the illustrated embodiment, the camera 50 is provided in the body molding device 31, and a discharge device (not shown) that blows out compressed air according to the discharge command 54 is the upper edge of the upper and lower edge processing device 33. It is provided near the discharge part of the processing turret 41.

Now, the process of preventing mixing of different types of container body parts will be described step by step. First, a bundle 3 of blanks 2 will be described.
The blanks 2 taken out one by one from 5 are supplied to the body forming device 31, and are heat-sealed in a state of being wound in a tubular shape to form the container body 45. In this state, the identification symbol 21 is visible from the outside as described with reference to FIG. Then, the camera 50 reads the identification symbol 21 while being conveyed by the turret 36 of the body forming device 31, and sends the signal to the control device 52 via the cable 51. Although various reading methods are conceivable, as a method for reading numbers as in the embodiment, the numbers are cut at lines 1 to 7 as shown in FIG. 7, and the lines are crossed. It is possible to adopt a method of checking whether or not the number is read and reading the number. For example, as shown in the figure, if the 1st, 2nd, 3rd, 4th, 5th, and 7th lines are ON and 6th is OF, the number is judged to be "6". In addition, as shown in FIG.
If the No. 5, No. 5, No. 6, and No. 7 lines are on and the No. 2 lines are off, the number is judged to be “0”. According to such a method, it is possible to automatically read the numbers "0" to "9". The identification code 21 read by the camera 50 as described above is the cable 5
1 to the control device 52. Here, in the control device 52, the identification signal 53 is preset by the operator. Therefore, when the body part of a different container is mixed, the identification symbol 21 and the setting identification signal 53 read by the camera 50 as described above. Will be different. As a result, the control device 52 compares the two and detects a discrepancy in the identification signals, and outputs a discharge command 54 to a discharge device (not shown) provided in the discharge portion of the upper edge processing turret 41. Thus, the dissimilar container body 55 of the container body in which the top curl portion 10 and the folding portion 11 are formed is discharged from the upper edge processing turret 41 to the waste box 56 by compressed air, and the identification signal 5 set by the operator is set.
Only the correct container body 45 that is judged to be the same as 3 is passed from the upper edge processing turret 41 to the container removing device 34, and a predetermined number of container body 45 are overlapped and sequentially discharged to the stacker 42. To be done. The container body 45 discharged to the stacker 42 in this way is
Is formed, the identification mark 21 is folded inward so that it cannot be seen from the outside.

Although one embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made. For example, the identification code may be provided in a portion that cannot be seen when the container is molded, and in any case, it may be provided in a location that does not impair the aesthetic appearance of the product. However, it is better not to describe it on the heat-sealed joint. If an identification symbol is written on the heat-seal joint, the part with ink adheres to the blank part on the inner surface of the container when peeled off, which may impair the cleanliness and appearance. Further, a symbol, a character, a figure, a barcode, a color or the like may be used as the identification symbol. If the identification mark is surrounded by the frame 23 as in the embodiment, the frame 2
It is convenient because you can use 3 to align the camera. A general image processor may be used as the camera. Furthermore, the present invention may be applied to the production of paper cups, as the different products may be discharged after the container body and the bottom member are attached.

[0013]

According to the blank of the present invention, since the identification symbol provided on the blank can be read during the manufacturing process of the container to determine the type, it is possible to reliably exclude the product consisting of different kinds of blanks. . Therefore, by preventing the mixture of different kinds of products, there is no fear that the products whose contents are different from the display are mixed. Further, since the identification code is provided at a position where it cannot be seen from the outside when the container is completed, the identification code is not seen from the outside when the product is completed, and the appearance is not impaired.
