Description

[Detailed description of the invention] [Field of industrial application] This invention is a packaging machine for binding the outer periphery of objects to be packed with thermoplastic tape, and more specifically, a packing machine for binding objects to be packed in a circular shape. This invention relates to a packaging machine suitable for bundling.

[Conventional technology and problems]

As shown in FIG. 3, the conventional packaging machine has a first clamp 2, a pressurizer 3, and a second clamp 4 arranged side by side directly below a base 1 located on a table so that they can be raised and lowered, and a reel 5. The thermoplastic tape A pulled out from the tape is passed through the tape feeding and tightening mechanism 6 and the passage hole 7 of the first clamp 2 to the second clamp 4.
and base 1 onto the table, and place the tip of tape A wound around the item B on base 1 on base 1.
When the tape A is inserted downward, the first clamp 2 is raised by the cam mechanism 8 driven by the motor M and clamps the insertion side of the tape A with the base 1, and then the tensioning mechanism 6 tensions the tape A. After that, the second clamp 4 rises and clamps the insertion end of tape A and the middle of the tape with the base 1, and then the pressurizer 3 rises and cuts the middle of the tape between it and the first clamp 2. After cutting by the mechanism, the heater enters between the upper and lower tapes directly above the pressurizer 3, and as the pressurizer 3 pushes up, the upper and lower facing surfaces of the tape A that sandwich the heater melt, and even after the heater is removed. Since the pressurizer 3 applies pressure, the opposing surfaces of the upper and lower tapes are welded together.

After the tape is welded, both clamps 2, 4 and pressurizer 3 are lowered, and when the base 1 is pulled out from between the annular tape and the object to be packed B, packing is completed and the delivery tensioning mechanism 6 is activated. The tape A is sent out a predetermined length above the base 1 in preparation for the next packing.

By the way, as shown in FIG. 3, the base 1 in a conventional packaging machine has a flat top surface, so it is suitable for packing objects that need to be bundled in a circle, such as flowers or wire rods. Even if an attempt is made to bind the tape, since the surface of the base 1 is flat, shape retention is extremely poor, and not only is it difficult to perform the work, but the length of the tape wrapped around the base 1 and the item B to be packed becomes long. , the tension of the tape becomes loose after packaging,
There is a problem in that it is not possible to obtain a strong packaging condition.

[Purpose of invention]

This invention was made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a packing machine that can maintain the shape of the objects to be packed well during packing and can obtain a strong binding state without loosening. is the purpose.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention has a structure in which the upper surface of the base is formed into a concave surface.

[Effect]

The top surface of the base is formed with a concave surface, which improves the shape retention of the items to be bundled into a circular shape.
The length of tape required for wrapping can be shortened accordingly, and a strong packaging finish with no loosening can be obtained.

〔Example〕

Embodiments of this invention will be described below with reference to FIGS. 1 and 2 of the accompanying drawings. Note that the same parts as in FIG. 3 are designated by the same reference numerals and their explanation will be omitted.

As shown in the figure, the upper surface of the base 11 is formed into a recessed surface 12, and the positions on both sides of the lower surface where the upper ends of the first clamp 2 and the second clamp 4 face each other are reversely inclined along the recessed surface 12. It is attached to surfaces 13 and 14.

In the illustrated case, the recessed surface 12 has an arc shape, but it may also be a polygonal recessed surface.The lower surface of the base 11 has a horizontal surface at the center facing the upper surface of the pressurizer 3, and an outer surface on both sides thereof. Upward slope 13, 14
The upper end surfaces of the first clamp 2 and the second clamp 4 are inclined surfaces corresponding to the inclined surfaces 13 and 14.

The width of the base 11 is made as narrow as possible within the range of conditions necessary for tape welding, so that no length loss occurs during tape winding.

In the case shown in the figure, the structure of the packing machine is such that the main components are attached to a swing plate 15, and the pulling out of the base 11 from between the tape and the object to be packed B is performed by swinging the swing plate 15 by a cam mechanism 8. Although the structure is shown in which the components are attached to a fixed plate, only the base is supported so as to be able to move laterally, and the base is moved by a cam mechanism.

The packaging machine of this invention has the above configuration,
For example, the objects B to be packed, such as flowers and wire rods, are placed in a bundle on the base 11, and the objects B are bound with the wound tape A.

The items to be packed B are bundled into a substantially circular shaft shape and placed on the base 1.
1, the cylindrical shape is maintained by the recessed surface 12 formed on the upper surface of the base 11, and the base 11 is narrow and both sides of the lower surface have sloped surfaces along the recessed surface 12. 13 and 14, it is possible to shorten the tape winding length around the object to be packed B and the base 11 when the tape is wound, and the object to be packed can be bundled in a circular shaft shape without loosening. can do.

〔effect〕

As described above, according to this invention, the upper surface of the base is formed into a concave surface, which improves the shape retention of objects to be packed such as bundling a large number of books into a circular axis. It can be packed in

Furthermore, the length of the tape wound around the object to be packaged and the base can be shortened, the occurrence of loosening of the tape after the base is removed is reduced, and a strong binding state with the tape can be obtained.
