Description

  The present invention relates to an automatic packing apparatus for a bundle of materials (hereinafter, referred to as a long binding material) in which a plurality of rod-shaped materials (hereinafter, referred to as long materials) such as steel bars and steel pipes are previously bound.

  Conventionally, long materials such as steel bars and steel pipes are required to simplify the loading and unloading of the long materials themselves into vehicles such as vehicles, and to prevent trauma of the long materials themselves or to prevent rust. Each bundle is bundled into a cylindrical shape or a prismatic shape, and one end or both end surface portions thereof are packaged with a sheet, and both longitudinal end portions or intermediate portions thereof are appropriately packed with an exterior material before shipment. When shipping in this bundled state, it is packed with packing materials as described above to prevent wrinkles and dirt, but it is difficult to perform packing corresponding to various shapes and lengths of bundles, Such a long bundling and bundling operation is generally performed manually by hanging a long bundling material at two or several points with a lifting device and then bundling the outer packaging. .

  As equipment for performing the above operation mechanically, as disclosed in, for example, Japanese Patent Laid-Open No. 7-52915 (Patent Document 1), an exterior material supply device that appropriately transports the exterior material to a predetermined position and a predetermined position are transferred. The outer packaging material separating / transferring device which receives only the upper one of the outer packaging material and transfers one side thereof to the upper side of the long bundle material positioned at a predetermined position, and the separating / transferring device above the long bundle material A pressing device that presses one side of the exterior material transferred to the long bundle material, and the pressing device rotates the long bundle material while pressing one side of the exterior material against the long bundle material. An outer packaging device for a long bundle material has been proposed, which includes an exterior machine that temporarily winds a wire around a long bundle material.

JP 7-52915 A

  Patent Document 1 described above is an apparatus that winds a sheet-shaped packing material while the long bundle is stationary, and in this case, the half surface that can be wound in a fixed position and the packing range are limited by the width of the sheet. On the other hand, since it can be wound only at the place where it is easy to generate wrinkles when it is stacked, it can save packing materials, and can be easily opened by the user, and there is a merit that there is little waste material. It is not suitable for long binding materials that require covering the entire surface with packing materials in the storage state (barrage, shipping, etc.).

  Further, when the work of winding the packing material in a spiral shape is automatically performed, it is difficult to (1) automate the tip (start of winding) in order to put this into practical use. (2) It is difficult to keep the winding state constant due to the difference in the outer diameter of the long binding material. (3) It is difficult to wind tightly when spirally wound. (4) There are various problems that it is difficult to automate termination processing.

In order to solve the problems as described above, the inventors have made extensive developments, and as a result, an automatic packing device that causes a long material to go straight in the longitudinal direction, and a belt-like packing material is wound around the material in a spiral shape for packing. Is to provide. The gist of the invention is that
An automatic packing device that bundles a plurality of long steel bars and steel pipes in advance in a longitudinal direction with a transport roller and spirally wraps a belt-like packing material around the long binding material In this case, the supply speed and supply angle of the packing material are automatically controlled by the diameter and winding pitch of the long binding material, and it is possible to automatically start winding by the chucking mechanism at the beginning of the belt-like packing material , and the shaft core After the packing material is wound around the end of the long binding machine by the variable angle mechanism, the angle of the shaft core can be changed, while the end of the packing material is temporarily fixed by the end cutting mechanism and taping mechanism, and the end packing The present invention is an automatic packing device for a bundle of materials in which a plurality of steel bars and long steel pipe materials are bundled in advance, which is characterized in that the taping processing of the material can be automatically performed.

  As described above, the automatic bundling device for long binding materials according to the present invention enables efficient packaging and bundling of exterior materials regardless of the long binding material of any outer diameter. The entire side surface of the material can be automatically packed without any manual intervention, and it can be appropriately selected to produce an extremely excellent effect of packing and binding any long binding material.

Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 is an overall side view of the long binding material exterior packaging apparatus according to the present invention. As shown in this figure, a long binding material 1 made of long steel bars, steel pipes, and the like is transported linearly in the longitudinal direction by a conveying roller 2 and supplied to an outer packaging device for the long binding material 1. Since the exterior packaging apparatus is disposed at the longitudinal position of the long binding material 1 supplied to a predetermined position, the transfer mechanism is configured by a lifting mechanism using a cylinder and a pushing mechanism to the exterior packaging apparatus using a cylinder.

  When the long binding material 1 is transferred to the longitudinal side position by the transport roller 2, the packing material 3 is transferred to the end of the long binding material 1. In order to prevent the long binding material 1 from being pulled up and lifted when the transported packing material 3 is wound, a presser device installed in the exterior packaging apparatus body is configured to press the long binding material 1 against the long binding material 1. The The configuration is a pressing roller 4 and a pressing roller lifting device 5. Reference numeral 6 denotes a flyer receiver lifting device, 7 is a flyer receiver, 8 is a flyer, and 9 is a flyer rotating motor. These devices are operated as follows.

  The flyer receiver lifting device 6 is a mechanism that moves up and down according to the diameter of the long binding material 1 so that the long binding material 1 becomes the center of the fryer 8 and the fryer receiver 7. Accordingly, since the long binding material 1 always comes to the center of the fryer 8, the packing material 3 can be wound with a uniform force. On the other hand, the packing material 3 is configured by a shaft angle variable mechanism 11 supported by the arm 10, a packing material paper core shaft 12, a terminal cutter 13, and a terminal taping device 14. Reference numeral 15 is a terminal unit moving device, 16 is a tip chuck, 17 is a supply device, and 21 is a static eliminating device.

  The operation of the shaft center variable mechanism 11 is comprised of these, and after the packing material 3 is wound around the end of the long binding material 1 as shown in FIG. 9, the angle of the shaft core is tilted up to 45 degrees. . This is a method of changing the angle by rotating the flyer 8 so that the shaft angle variable mechanism 11 comes to the position of the supply device 17, supplying power from the supply device 17, and tilting the shaft angle variable motor to a predetermined angle. is there.

  Since the conveyance speed of the conveyance roller 2 of this apparatus is constant even if the diameter of the long binding material 1 is changed, the winding angle is changed when the diameter of the long binding material 1 is changed, and the packing material 3 is spiral-shaped. When it is wound around, there is a gap or a state in which it cannot be tightly wound. In order to prevent this, the shaft angle is adjusted so that there is no gap, and the tight packing material 3 can be wound around the long binding material 1. Furthermore, the amount of overlapping of the packing material 3 can be set in this apparatus. This is because the amount of overlap can be adjusted freely by adjusting the angle of the shaft core by the shaft angle varying mechanism 11 and adjusting the rotational speed of the fryer 8 from the diameter and the amount of overlap of the long binding material 1. It is a mechanism that can.

  When the packaging material 3 is wound around the long binding material 1, the packaging material paper core shaft 12 is a device that incorporates a torque limiter for tightly winding the packaging material 3 and winds the packaging material 3 in a state where a prescribed tension is maintained. After the packaging of the long packaging material 3 is finished, the packaging material 3 waits at the position of 0 degrees which is the original state by the shaft core angle variable mechanism 11. At this time, the packing material 3 is chucked by the tip chuck 16. In this state, the terminal unit moving device 15 moves and moves to the front of the packaging material 3, cuts the packaging material 3 with the terminal cutter 13, and then fixes the terminal of the packaging material 3 with the terminal taping device 14 with a tape. When the packing material 3 is a synthetic resin, the static electricity removing device 21 is a device that removes a large amount of static electricity that is generated by being wound in a spiral state.

  FIG. 2 is an overall front view of the long binding material exterior packaging apparatus according to the present invention. As shown in this figure, the equipment configuration is such that the arm 10 holding the packing material 3 is directly connected to the fryer 8. A rack 19 is disposed on the outer periphery of the fryer 8, and is a mechanism in which the fryer 8 is rotated for each arm 10 holding the packing material 3 by a fryer rotating motor 9. The flyer 8 is received by a flyer receiver via a cam follower 18, and the flyer receiver is lifted and lowered by the flyer receiver lifting device 6 so that the long packaging material 3 is always at the center of the flyer 8.

  FIG. 3 is a diagram showing a state in which a long binding material is wound in a packing shape in a spiral shape. As shown in this figure, the packing work of automatically winding the strip-shaped packing material 3 around the long binding material 1 is performed in a spiral manner, and the side surface excluding the end surface of the long binding material 1 by winding in a spiral shape. The entire surface can be covered with packing materials.

  FIG. 4 is an overall front view showing the tip of the packing material. FIG. 5 is an overall perspective view showing the tip of the packing material. FIG. 6 is a view showing a state in which the front end of the packing material is wound around the long binding material in a state where the front end is grasped by the front end chuck. FIG. 7 is a view showing a state in which the tip chuck is retracted after the front end of the packing material is wound around the long binding material.

  As shown in FIGS. 4 to 7, after winding the long binding material 1 in a state where the leading end of the packing material 3 is gripped by the leading end chuck 16 for about two rotations, the leading end chuck 16 is opened. Winding is started in a spiral shape with the tip chuck 16 retracted and the tip chuck 16 removed. In that case, by controlling the rotational speed of the fryer 8 according to the outer diameter of the long binding material 1, the uniform overlap amount and the tightening strength can be made constant.

  FIG. 8 is a detailed view showing the opening and back-and-forth movement mechanism of the tip chuck. FIG. 8A is a top sectional view, and FIG. 8B is a front sectional view. As shown in this figure, the front end chuck 16 is opened after being wound around the long binding material in a state where the front end of the packing material is gripped by the front end chuck 16 by a chuck opening / closing mechanism. Thereafter, the tip chuck 16 is retracted by the chuck back-and-forth advance mechanism 24 and is wound in a spiral shape with the tip chuck 16 removed.

  FIG. 9 is a diagram illustrating winding in a state in which the packing material is arranged at right angles on the long binding material. FIG. 10 is a diagram illustrating winding in a state where the packing material is directed obliquely with respect to the long binding material by the shaft center angle adjusting mechanism. As shown in FIG. 10, it is possible to wind the packing material tightly by winding the packing material 3 obliquely with the shaft angle adjusting mechanism.

  FIG. 11 is a diagram illustrating a cutting and taping processing mechanism of the end packing material. As shown in FIG. 11, the terminal packaging material is cut by the terminal cutter 13 and the taping process is performed by the terminal taping device 14 so that these can be automatically processed. Reference numeral 15 denotes a terminal unit mobile device.

  FIG. 12 is an overall view showing a series of arrangement states of the packing machine according to the present invention. FIG. 12A is a top sectional view, and FIG. 12B is a front sectional view. As shown in FIG. 12, three automatic packing machines 26, 27, and 28 are arranged in series following the charging-side conveyance roller 25, and then the discharge-side conveyance roller 27 is continuously and integrally arranged. Is. Thus, different packing materials can be packed at the same time.

  Further, the automatic packing machine 26 is a device for winding a packing material having good spreadability such as a film with the packing machine, and does not have a variable axis angle mechanism. This is because in the case of a packing material having good spreadability, a tight packing material can be wound around the long binding material without changing the axial center angle. Further, the automatic packing machine 28 is a device for winding the packing material in a band shape at a predetermined position instead of a spiral shape. Furthermore, the resin hoop binding machine is also installed in the line, and the one temporarily bonded by taping at the termination processing unit is bound by the resin hoop. By combining in this way, it is possible to configure a line that can handle various packing materials.
