Description

DETAILED DESCRIPTION OF THE INVENTION a) Industrial field of application The present invention is a method for wrapping two parallel cylinder bodies or cylindrical bodies such as dry batteries (hereinafter simply referred to as dry batteries) with a heat-shrinkable resin film tube. Regarding a packaged dry cell battery that can be displayed and sold at
The present invention relates to a method of packaging two parallel dry batteries with the trademark or company name printed on their circumferential surfaces facing forward, and the dry batteries packaged by the method.

b) Conventional technology When wrapping two parallel dry batteries in a heat-shrinkable resin film tube such as PVC, the most basic packaging method used to be to wrap the circumferential surface of the dry batteries in a tube and integrate them. What has been done is well known.

However, although this circumferential packaging method is the most reliable in terms of integrating two dry cells, both electrode surfaces of both dry cells are exposed, so poor contact due to discharge or dirt is likely to occur.

Therefore, in order to eliminate the above-mentioned disadvantages, a packaging method along the longitudinal direction of a pair of parallel dry batteries was devised, in which the upper and lower pole surfaces and both the front and rear circumferential surfaces are wrapped in a film tube.

However, heat-shrinkable packaging using only film tubes has the disadvantage that it cannot be displayed and sold in a suspended state.

Japanese Utility Model Publication No. 52-14904 improves the above-mentioned longitudinal packaging method to make it possible to hang the battery by making a locking piece come into contact with and protrude from the positive electrode of the dry battery, and surrounding the whole with a tube. A packaged dry battery is disclosed in which the locking piece is heated to flatten the locking piece after being heat-shrinked, and a locking hole is formed therein.

Next, Utility Model Publication No. 53-14903 describes a main body having an area corresponding to the projected area of two parallel dry batteries to be packaged to enable hanging, and a protrusion on the upper edge of the main body. Prepare a mount consisting of a locking piece that is narrower than the main body of the mount, place a pair of dry batteries side by side on the main body of the mount, and then wrap the batteries and the mount main body with a heat-shrinkable resin film. A packaged dry battery is disclosed which is surrounded by a tube.

C) Problem to be solved by the invention When two dry batteries are integrated and packaged in parallel, the trademark or company name displayed on the periphery of each dry battery is placed on the front periphery where it is easily seen. As such, it is necessary to manipulate the orientation of each dry battery, that is, to align the marks.

In the process, workers manually adjusted the orientation of each battery just before heat-shrinking the film tube. However, when a dry cell battery is rotated within a thin film tube, the film tube clings to the battery as it rotates, creating an obstacle to packaging. Therefore, there was a disadvantage that the work required skill and the production cost was high due to labor costs etc. despite the low productivity.

An object of the present invention is to provide a packaged cylindrical body and its packaging that enables the above-mentioned mark alignment to be performed automatically by mechanical operation, and that enables production costs to be reduced despite a significant increase in the number of units produced. The purpose is to provide a method.

d) Means for solving the problem: First, a main body having an area approximately equal to the projected area of two parallel dry batteries to be packaged, and flaps provided along both sides of the main body and having at least a smooth back surface. and a heat-shrinkable resin film tube having a length approximately equal to the width of the main body and a circumferential length that allows the two dry batteries to be packaged to be inserted therein. The rear outer surface of the tube and the front surface of the main body portion are overlapped with each other, and the flap portions are folded back and fixed to the inner surface of both ends of the tube, and then two Insert the batteries in parallel, and then...

Rolls are pressed against the exposed outer peripheral surfaces of the two inserted dry batteries, and each roll is rotated to rotate each dry battery in a driven manner, and their orientations are converted and adjusted to the desired phase, respectively. Finally, the film tube is heat-shrinked to wrap the dry battery, which is the method of packaging a cylindrical body according to the present invention.

In the cylindrical body thus formed and packaged according to the present invention, both outer circumferential surfaces of two parallel dry cells are exposed, and both the front and rear circumferential surfaces and the upper and lower pole surfaces are wrapped in a heat-shrinkable resin film tube. However, the rear outer surface of the tube that is in contact with the dry battery is in contact with a main body part of a mount having an area approximately equal to the projected area of the dry battery, and each flap part is provided along both sides of the main body part. are each folded back inward, and the rear side edge portions of the tube are held and fixed between the main body portion and each of the flap portions, and each rear peripheral surface portion of the pair of dry batteries is folded back. They are wrapped in contact with each flap surface.

e) Function At the rear circumferential surface of the pair of dry cells, the rear side edges of the film tube are sandwiched and fixed between the main body and the flap of the mount, so even if the dry cell is rotated, the film tube will not move. Not only is there no risk of the batteries clinging to each other as they rotate, each battery is placed on the smooth surface of the flap, and the smooth surface is used as a base for easy rotation. If the rolls are pressed against the outer peripheral surface portions and rotation is transmitted, the dry cells are easily driven to rotate, and the direction of each dry cell can be changed to a desired phase.

If a hanging part is provided, it should be provided along the upper edge of the main body of the mount, and not near the roll pressure contact position, so that the pressure contact of the roll to the dry battery is not hindered, and the orientation by rotation can always be reliably performed. be able to.

Now, in FIG. 2, the mount l to which the tube 9a is attached
is 2 at point d on the peripheral surface 5a of the main turret 5.
The glue is sprayed from the gun 12 onto the front surfaces of the left and right flap portions 1b and lc, and then, at point e, the tube 9a is opened wide, and then at point f, Both the flap portions 1b and the IC are folded back inward by pushers 13 and 14 from left and right opposing directions, respectively, and are pressed against the adhesive surface of the tube 9a. That is, each flap part 1b and lc folded back in the first drawing is connected to the tube 9 as shown by 111E.
The rear side edges of a are firmly sandwiched and adhesively fixed between the main body portion 1a of the mount 1.

As shown in FIG. 2, at point g on the circumferential surface 5a of the main turret 5, dry batteries 15 and 16 are waiting at positions on both sides thereof, and at point h, both batteries are pushed into the bush 17 from opposite directions on the left and right. and 18 into the tube 9a. The inserted pair of dry batteries 15 and 16 are placed on the respective folding flaps 1b and lc, as shown in the second diagram and FIG. 1F.

In addition, in FIG. 2, the dry batteries are sorted into two rows by a star foil 19, and are supplied to point g on the circumference of the main turret by a ladder chute 20.

The circumferential surfaces of the rolls 21 and 22 are made of a friction-rich material, such as rubber, or have an uneven surface, so that their rotation is transmitted to the circumferential surfaces of the dry batteries 15 and 16. Since each dry cell is in contact with the smooth upper surfaces of the flap portions 1b and 1C, it can be rotated without resistance. When the pattern detection sensors 28 and 29 detect the eye mark or trademark or company name display on the peripheral surface of the dry cell batteries, the signals are sent to the brakes 25 and 26, respectively, and the rotation of the dry cell batteries is stopped. The display of the trademark or company name both stands still in a rotational phase facing upward.

Once the circumferential alignment of the pair of batteries has been completed, they are transferred into a well-known tunnel of heaters 36 to heat shrink the film tube, thus completing the packaging (see FIG. 2).

In FIGS. 3 and 4, 37 is an operation panel, and 38 is a relay box.

It is also possible to provide magnetism to the circumferential surfaces of the rolls 21 and 22 so that they come into contact with the surface of the dry cell battery and transmit rotation.
