Description

  The present invention relates to an assembling method and an assembling apparatus for a cylindrical body that assembles a cylindrical body such as a paper bobbin by rounding thick paper.

  In order to wind a long object such as a hose or a wire rod, a paper bobbin made up of a cylindrical body and circular gutters attached to both sides thereof may be used. In this case, the barrel body is generally assembled into a cylindrical shape by rolling cardboard and matching both ends. Conventionally, as a connecting means for holding the butting of both ends, a plurality of conventionally provided check pawls at one end of the cardboard are provided. The connecting piece is formed so as to protrude, and a connecting hole into which the connecting piece is inserted is provided at the other end (Patent Document 1).

  However, in this case, it is inevitable that the butt portion is a combination of the connecting piece and the coupling hole, and unevenness is generated on the outer surface, and the unevenness is an obstacle to orderly winding a long object. In this regard, if a backing such as an adhesive tape is bonded to the inner surface of the abutting that rolls the cardboard, the outer surface of the body is flush and the problem is solved. However, this is problematic and difficult to implement.

  When using a backing, first of all, the cardboard as a curved plate material is brought into contact with the both ends on the table while contacting both ends, and the backing is adhered to the inner surfaces of both ends of the cardboard while maintaining this state. It becomes the work sharing between the person who holds the butt and the person who bonds, and it is very difficult to keep the butt state, and if you try to make a butt, you will go too far and double and try to avoid it If you are careful, the butt will be spaced and uneven. In addition, when the diameter of the body part to be assembled is small, it is difficult to put the hand into the rolled body, so that not only the butting becomes more difficult, and the connecting pieces cannot be easily bonded.

  In view of the above situation, when assembling a barrel body into a cylindrical shape with a curved plate material such as cardboard, the present invention is adapted to accurately match both ends of the body while accurately holding the both ends. It is an object to provide an assembling method and an assembling apparatus for a cylindrical body that can be adhered to each other in an orderly manner and can be easily assembled even if it is a small cylindrical shape that is inaccessible and suitable for labor saving. It was.

  In order to solve the above-mentioned problems, the present invention is an assembling method of a cylindrical body part in which both ends of a curved plate material are joined by adhesion of a butt backing, which is pressed against the upper cradle from below. The press board is formed with a circular arc surface that is the same or nearly the same as the circle centered below the upper pedestal, and the upper pedestal is provided with a slit in which the thin plate is suspended at the center of the width. By holding the weight bar on which the thin plate is suspended on the upper cradle, the thin plate is suspended from the arc surface of the upper cradle against the gravity of the weight bar and pressed. In a state where the backing is temporarily fixed on the arc surface of the board, by rounding the curved plate so that both ends abut on the press board, both ends are butted against the thin plate under the arc surface of the upper cradle, Pushing up the thin plate by raising the press panel Provides a method of assembling a cylindrical barrel body, characterized by bonding the backing to retract the slit on the inner peripheral surface of the song was plate.

In addition, the present invention is provided with a long stand in the front-rear direction protruding from the upper end of the support, and an upper frame is provided on the long stand in parallel with the upper frame in a cantilever manner via a supporting vertical member. A left and right belt plate material in which the upper frame is formed by providing a press plate at the front end of the plate so that it can be moved up and down via a fluid cylinder, and providing an upper cradle as an opponent against which it is pressed above the press plate. by providing fixed the upper receiving base under, are vertically capable decorated weight bar between the two strip plate material, a slit is provided in the width center of the upper receiving base, the weight bar exits the slit A thin plate that hangs downward from the upper cradle is attached so as to be retracted by the upward movement of the weight bar, and a circular arc surface having a center below the upper cradle is formed on the relative surface between the upper cradle and the press board. Of a cylindrical body characterized by being formed There is provided a stand apparatus.

  According to the above configuration, both ends of the curved plate material are abutted with a thin plate in between, so that both inside and outside are flush with each other without being doubled, and the abutment between both ends is uniform over the entire length with the thickness of the thin plate. The backing can be adhered to the inner surface while maintaining that state.

  As described above, according to the present invention, when assembling the trunk body into a cylindrical shape with a curved plate material such as cardboard, the both ends are abutted and precisely abutted while the both ends are securely held. Since it can be adhered by backing in an orderly manner, it is possible to prevent inconveniences that steps and irregularities occur on the outer periphery of the trunk body, and it is easy to assemble even if it is a small cylindrical shape that can not be reached, and it can be done alone There is an excellent effect that it is possible and suitable for labor saving.

It is a front view of the assembly apparatus of the cylindrical trunk | drum which shows one Example which concerns on this invention. It is a side view of the assembly apparatus. It is an expanded sectional view which shows the principal part of the assembly apparatus. It is an expansion perspective view which shows the principal part of the assembly apparatus.

  Hereinafter, embodiments of the present invention will be described in detail.

  In the present invention, the body as an object to be assembled is a cylindrical body that can be made into a product by being coupled with others, and in the embodiments shown below, it is described as being used as a body of a paper bobbin. However, it may be used as other products such as a cylindrical case or a body of a hat.

  In addition to the cardboard 10, a corrugated cardboard, a plastic plate, a wood thin plate, or the like is used as the curved plate material. Moreover, since the backing 33 adheres to the inner surface of the butted portion of the curved plate material, at least the upper surface is coated with an adhesive. The holding means for the press board 9 is not limited to adhesion, and other means such as other suction force can be taken.

  FIG. 1 and FIG. 2 are a front view and a side view showing the whole assembly apparatus P of a cylindrical body, and a column 1 is erected on a seat plate 2 so that the height can be adjusted. A narrow gantry 3 in the front-rear direction is provided at the upper end, and main devices are mounted on the gantry 3 as a whole. A hydraulic petal 4 is arranged so that the device can be operated with the foot. Reference numeral 6 denotes a hydraulic box in which a hydraulic tube is arranged on a hydraulic petal.

  As for the main device, an upper frame 5 having a length approximately the same as that of the upper base 3 is provided in parallel, and is supported in a forward projecting form by support vertical members 7 and 7. In addition, a press plate 9 that is also long in the front and rear directions is supported on an air cylinder 11 on the front half of the long base 3 so that it can be moved up and down. A base 8 is fixed, and a vertically movable weight bar 13 is provided in the upper frame 5, and a thin plate 15 is suspended in the center of the width, and the thin plate 15 is suspended from the width center of the upper receiving base 8. . Further, a rear plate 12 is provided at a portion located at the rear end of the upper cradle 8 in order to abut the cardboard 10 so as to be aligned, and is connected to the long base 3 and the upper frame 5.

  In addition, the seat plate 2 is provided with sub-bases 16 and 16 on both the left and right sides below the press board 9, and the sub-bases 16 and 16 are provided with sub-posts 17 and 17 so that the cardboard 10 is loaded. Long and narrow pedestals 19 and 19 are provided and are formed in an inverted T shape. The both bases 19 and 19 are put on standby with the thick paper 10 to be assembled.

  The upper frame 5 is assembled with a pair of left and right strip plates 21 and 21 facing each other, and a weight space 13 between them is a holding space in which the weight bar 13 freely moves up and down. Further, the upper cradle 8 is screwed to the strip plates 21 and 21, respectively. This also comprises left and right members 23, 23, between which a guide slit 25 is provided through which the thin plate 15 of the weight bar 13 can pass up and down. The upper cradle 8 is composed of the left and right members 23 and 23 with the guide slit 25 therebetween as described above, but the lower surface is formed on the circular arc surface 27 of the same circle over both. To this, the attachment plates 29 and 29 in which the circular arc surface 27 is formed in half are fixed to the lower surfaces of the left and right members 23 and 23.

  On the other hand, the press panel 9 is mounted on a rod of the air cylinder 11 via a base 31 and has an upper surface formed on an arc surface 28 having the same circle as the arc surface 27 of the upper cradle 8. Since it is necessary to fix the backing 33 on the arc surface 28, double-sided adhesive paper (tape) was used for the backing 33, and it was adhered along the arc surface 28 and attached. However, instead of using double-sided adhesive paper, single-sided adhesive paper may be used. For example, a number of air suction ports may be provided on the circular arc surface 28 and the air may be sucked by air pressure. Next, how to operate the assembly apparatus P will be described.

  In the initial state, the thin plate 15 of the weight bar 13 hangs under the upper cradle 8, and the press panel 9 is located at a distance from the height of the thin plate 15. In this state, the backing 33 is placed on and adhered to the arc surface 28, and then the cardboard 10 is rolled up while the rear end of the backing plate 12 is along the rear plate 12, and the upper end is abutted against the thin plate 15. As a result, the cardboard 10 comes into contact with the circular arc surface 27 with the thin plate 15 sandwiched by the upward elasticity to be restored, so that both ends of the cardboard 10 are exactly matched (the state shown in FIGS. 1 and 3 except that the thickness of the thin plate 15 is There is a slight interval of only minutes).

  Next, when the petal 4 is stepped on and the press board 9 is pushed up by the air cylinder 11, first, the press board 9 pushes up the thin plate 15 against the gravity of the weight bar 13, so that the arc surface 28 of the press board 9 is back. The cardboard 10 is pressed firmly against the arc surface 27 of the upper cradle 8 together with the pad 33, and both of them are bonded. When the press board 9 is lowered by releasing the air, the backing 33 is peeled off from the arc surface 28 of the metal surface which is relatively difficult to adhere, and the cardboard 10 is adhered to the both butted portions.

  The cylindrical shape obtained by rolling the cardboard 10 is not necessarily a perfect circular cylindrical shape depending on the material and strength of the backing 33 and other conditions. However, in the case of a bobbin, for example, in combination with the hooks at both ends thereof, and in the case of the case, in combination with the bottom plate, a perfect circular shape or a cylindrical shape close thereto is maintained. Further, a slight gap corresponding to the thickness of the thin plate 15 is generated between the butting of the thick papers 10, but this is not inconvenient enough to be ignored in the case of the bobbin. In many cases, the gap is sealed by the exterior, which does not cause a problem.
