Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pallet that supports a cylindrical object that is long in the axial direction.

[0002]

[Prior Art]

 When printing on film or paper to manufacture a package, set a roll (hereinafter referred to as “cylinder”) that has irregularities corresponding to the characters and patterns to be printed on the printing machine. The cylinder has a cylindrical shape elongated in the axial direction as shown in FIG. 6 (a). Conventionally, as shown in FIG. 6 (b), a pair of wedge-shaped supports 52 are fixed on a pallet substrate 51 to form a pair of support surfaces 53 intersecting each other at an angle smaller than 180 °. The cylinder 50 is mounted on the pallet 50 by using the 50 and is transported between the automatic warehouse and the printing machine or stored in the warehouse. When supplying the cylinder S to the printing machine, an operator lifts the cylinder S from the pallet 50, mounts it on the handling carriage, and then mounts it on the printing machine.

[0003]

[Problems to be solved by the device]

 However, in the case of multicolor printing, several cylinders S are required for one type of package, and there are many types of packages. Therefore, the number of cylinders S is enormous. On the other hand, the cylinder S has a weight of about 50 kg, and needs to be frequently replaced in order to cope with lot production of various kinds. Therefore, the work of lifting the cylinder S from the pallet 50 and remounting it is a heavy labor, and therefore labor saving is required.

The present invention has been made in view of the above-described conventional problems, and facilitates the work of remounting a transferred object in a pallet that supports a cylindrical transferred object that is long in the axial direction, such as a cylinder. With the goal.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a pair of wheels that come into contact with the outer peripheral surface of the lower portion of a cylindrical object that is long in the axial direction and that rotate when the object is moved in the axial direction. The trochanters are provided so as to be separated from each other in the radial direction of the transported object, and a plurality of pairs of the rotator pairs are arranged in the axial direction to form a supporting surface of the transported object.

[0006]

[Action]

 According to this invention, a plurality of pairs of rotary rollers that rotate when the transported object is moved in the axial direction are provided to form the support surface of the transported object, so that the transported object is transferred from the pallet to the carriage. When transferring, the trochanter rotates by pulling out the transported object in the axial direction. Therefore, it is possible to carry out the work of transferring the transported object with a light force.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a front view of a pallet. In this figure, a pallet P comprises a vertical frame 2 on which a pair of upper and lower frames 3 and 4 are erected to form an iron frame 1. The upper frame 3 and the lower frame 4 can accommodate, for example, 5 and 4 cylinders S, respectively.

As shown in FIG. 2B, each of the upper frame 3 and the lower frame 4 is welded with a bracket 5 of a mountain shape or the like having an inclined surface 5a. A pair of projecting plates 11 that rotatably support a resin roller (roller) 6 via a support shaft 7 are welded to each inclined surface 5a of these brackets 5.

As shown in the plan view of FIG. 3 and the plan sectional view of FIG. 4, the pair of rollers 6 are arranged side by side in the axial direction A of the cylinder (object to be conveyed) S. As shown in FIG. 2 (b), these rollers 6 are in contact with the outer peripheral surface Sf of the lower part of the cylinder S and rotate when the cylinder S is moved in the axial direction A (FIG. 2). The cylinder S is supported by forming a pair of support surfaces 8 which are provided apart from each other in the radial direction B of the cylinder S and intersect with each other at an angle smaller than 180 °. Note that, as shown in FIGS. 3 and 4, the mounting pitch of the rollers 6 becomes smaller toward the end of the cylinder S in the axial direction A. 3 and 4, only half of the pallet P is shown, but the pallet P is constructed symmetrically in the axial direction A.

As shown in FIGS. 3 and 4, bar stoppers 9 that are long in the horizontal direction are provided at the ends of the upper frame 3 and the lower frame 4 in the axial direction A, respectively. The bar stopper 9 contacts the surface ends Sa of the several cylinders S to prevent the cylinders S from falling on the pallet P. As shown in FIG. 2 (a), the bar stopper 9 is removable by inserting an insertion portion 9a into a vertical pipe 10 provided upright on the upper frame 3 (lower frame 4). The bar stopper 9 has a stopper portion 9b that is long in the horizontal direction and is slightly displaced in the direction of arrow A with respect to the insertion portion 9a in FIG. 3, and the position shown by the solid line and the position shown by the chain double-dashed line are shown. It can be selected and installed.

Next, a method of using the pallet P will be described. The pallet P is carried, or stored, on the mounting table 12 as shown in FIG. 5, or on a dolly, a chain conveyor, a stacker crane, etc. not shown. For example, in order to take out the cylinder S on the pallet P and place it on the fork 13a of the handling carriage 13, first, the level of the fork 13a of the handling carriage 13 is set to the level of the lower frame 3 or the upper frame 4 of the pallet P. After that, the bar stopper 9 shown in FIG. 3 is removed, and the cylinder S is pulled out in the axial direction A. At this time, since each roller 6 rotates, the cylinder S can be pulled out from the pallet P with a light force. The pulled-out cylinder S is mounted on the fork 13a of the handling carriage 13 of FIG. 5, and then mounted at a predetermined position of the printing machine. The operation of placing the cylinder S on the pallet P is the reverse of the above-mentioned operation of pulling out, and the description thereof will be omitted.

By the way, in the above-described embodiment, as shown in FIG. 1, since the rollers 6 are provided in the upper and lower stages of one pallet P, and a plurality of rollers 6 are provided in the lateral direction, a large number of cylinders S are provided. It can be stored or transported in a small space. However, in this invention, one cylinder S may be mounted on one pallet P.

Further, as shown in FIG. 3, the bar stopper 9 can be attached by selecting either the position of the solid line or the position of the chain double-dashed line, so that the cylinders S having different lengths can be stored without rattling. You can Needless to say, cylinders S having different diameters can be mounted as shown in FIG.

Further, in the above embodiment, the case where the object to be transferred is the cylinder S has been described, but the present invention is applied to the object to be transferred which is a cylinder or a cylinder long in the axial direction A.

Further, although the roller 6 is used as the rotator in the above-mentioned embodiment, a drum-shaped roller or a spherical roller may be used if necessary. Furthermore, a caster may be provided below the pallet P 1 in the above embodiment to form a pallet in the form of a hand truck.

[Effect of the device]

 As described above, according to the present invention, a pair of rotators that rotate when the transported object is moved in the axial direction are provided separately from each other in the radial direction of the transported object, and further, A plurality of pairs of roller rollers are arranged in the axial direction to form the support surface of the transported object, so when transferring the transported object from the pallet or when mounting the transported object on the pallet, Since the slab rotates, the replacement work becomes extremely easy.
