Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a label forming apparatus for forming a label such as a size display and a laundry display attached to clothes, towels, and the like. The present invention relates to an apparatus for forming a folded label.

[Conventional technology]

Cut into a label of a predetermined size of the band-shaped body, and fold the intermediate part of the label into two by extruding it by a predetermined size with an extruded piece into a gap provided in the receiving member, and grip it with a gripping tool. A known device is known (for example,
63-281681).

[Problems to be solved by the invention]

In this conventional device, the label can be folded in two so that the length of the portion to be gripped by the gripper and the length of the portion protruding from the gripper have predetermined dimensions. However, when the length of the label is changed, for example, to be short, there is a problem that the length of a portion protruding from the gripping tool becomes short. For example, when the label is moved to the position where the label is attached to the cloth by moving the gripper, if the length of the label is different, the place where the end of the label is attached to the cloth is changed.

The present invention has been made in view of the above points, and its purpose is to fold a long label or a short label into two so that the length of a portion protruding from the gripper is the same. It is an object of the present invention to provide a label folding apparatus and a label folding apparatus.

[Means for solving the problem]

In order to achieve the above object, the present invention employs the means described in the claims, and the operation is as follows.

[Action]

The strip is cut by the cutting device to form a label. The label is positioned at the label location, and then the extruded piece extrudes the middle of the label in two through a gap in the receiving member. The extruded label is gripped by the gripper.

Is folded as shown by reference numeral 52, the ruler 49 is removed, and a portion shown by reference numeral 53 is sewn to form a hem.

Next, formation of a two-fold label and supply of the two-fold label by the two-fold label forming apparatus 1 will be described. In FIG. 1, the strip 4 is fed by a feed roller 9 to the left of the drawing. When the sensor 11 detects the mark 4a, the feeding is stopped there, and the strip 4 is cut by the cutter 10 to form one label 5. In this case, the cut label 5 is located at the storage location 26 as apparent from the structure. The cutter 10 and the bending device in the cutting device 3
The distance L1 from the gap 31 at 27 is 1 / the length of the label 5
The setting is made in advance to be 2. Next, cylinder 3
The fourth piston rod 34a is extended so that the pushing piece 32 pushes the intermediate portion of the label 5 at the location 26 and pushes it upward through the gap 31 as shown in the figure (see FIGS. 4 and 5). The pushing piece 32 advances to a position where the contact member 37 contacts the stop surface 39. Next, the gripping parts 44, 4 of the gripper 28
4, the extruded label 5 is elastically gripped. Next, the cylinder 34 contracts and the extruded piece 32 is retracted.
Next, the gripper 28 is laterally moved to the supply position B by the transfer device 42. As a result, a portion of the label 5 protruding from the gripping tool is located at a predetermined attached portion. After the label is positioned at the attached portion, the edge of the cloth 50 is folded as indicated by reference numeral 52 by the above-described movement of the folding tool 48. As a result, the end of the label 5 is sandwiched inside the folded portion 52. After such a state, the pair of gripping pieces 43 are released, and the gripping tool 28 in that state is returned to the gripping position A again. The above operations are repeated one after another, and the formation and supply of the two-fold label are repeated.

Next, an operation when the length of the label is changed to, for example, a short one will be described. In this case, as shown in FIG. 2, by turning the handle 19 of the changing device 13, the distance between the cutter 10 and the sensor 11 is shortened and the dimension of the label is changed (between the cut portion detecting marks 4a, 4a). Distance). In this case, as described above, since the ratio of the moving dimension of the frame 8 to the sensor 11 is set to 1: 3, the interval L1 is automatically set to 1/2 of the length of the label. In this state, the same operation as that described above is performed. In this case, the advance of the extruded piece 32 is limited by the contact of the contact member 37 with the stop surface 39 while the amount of advance is still small. Therefore, the penetration depth L2 of the extruded piece 32 with respect to the label receiving portion 45 is limited to be smaller than that in the case of FIG. The decrease in the amount of advance of the extruded piece 32 in the case of FIG. 2 as compared with the case of FIG. 1 is because the stop surface 39 is formed at a 45-degree inclination.
It is equal to the decrease of the interval L1. As a result, the length L3 of the portion of the label 5 protruding from the gripper 28 is the same as that in the case of FIG. Therefore, when the gripper 28 reaches the supply position B, the lower end of the label 5 is placed on the cloth 50 under the same conditions as in FIG.
Is attached to a predetermined attached part of.

Next, in the two-fold label forming apparatus 1 having the above configuration,
As described above, since the table 25 is formed in the shape of a blade,
Even if the label has a narrow width as shown by the reference numeral 5 'in FIG. 6, it can be properly positioned in the place where the label 26 is located. Can be folded.

〔The invention's effect〕

As described above, in the present invention, the gripper 28 is positioned at a fixed position, and the amount of advance of the pushing piece 32 is limited by the ruler means 36. In this case, simply pushing the extruded piece 32 forward to a position limited by the ruler means 36 causes the label 5 to have a length L2 that is gripped by the gripper 28 and a length L3 that protrudes from the gripper 28. Each of them has a feature that it can be folded in two into a state having predetermined dimensions.

Further, when the length of the label 5 is changed to be short, for example, the advance amount of the pushing piece 32 restricted by the ruler means 36 is changed to be small, so that the length L2 of the portion gripped by the gripping tool 28 is changed. And the length L3 protruding from the gripper 28 can be folded in two so that the length L3 is the same as the above case.

As described above, in the present invention, there is an applicability that enables various labels having different lengths to be folded in two so that the lengths of the portions protruding from the holding tool are the same.

Further, in the present invention, when the setting of the limit of the advance amount of the extruded piece 32 is linked to the change of the cutting size of the label, when the length of the label 5 is variously changed, only the change of the cutting size is required. With the simple operation, there is an operational effect that the label whose length has been changed can be folded in two so that the length L3 of the portion protruding from the gripper 28 is constant as described above.
