Detailed Description

Example 1

Hereinafter, embodiments according to the present invention will be specifically described with reference to the drawings. First, an outline of a printing apparatus 1 according to embodiment 1 of the present invention will be described with reference to fig. 1. In fig. 1, some of the components are omitted for the sake of easy understanding of the structure. Here, the X-axis direction in the figure is a horizontal direction and a direction corresponding to a scanning direction B of the carriage 6 described later, the Y-axis direction is a horizontal direction and a direction orthogonal to the X-axis direction, and the Z-axis direction is a vertical direction. Further, hereinafter, the arrow mark direction is set to the + direction, and the direction opposite to the arrow mark direction is set to the-direction. For example, the vertical upper direction is defined as + Z direction, and the vertical lower direction is defined as-Z direction.

The printing apparatus 1 of the present embodiment is configured to perform printing by supplying ink from an ink cartridge 3 containing ink as a liquid to a head 4 as a printing portion via a tube or the like not shown, and discharging the ink from the head 4 to a medium conveyed in a conveying direction a by a conveying mechanism not shown.

The printing apparatus 1 of the present embodiment is configured such that, although detached in fig. 1, a rotary shaft capable of placing a rolled medium is provided on the back surface side, and the medium can be fed to a printing area where printing is performed by the head 4 by rotating the rotary shaft. Although the printing apparatus 1 of the present embodiment can use a roll-shaped medium as a medium, the present invention is not limited to a printing apparatus that can use such a roll-shaped medium. For example, a sheet-type medium such as a sheet of paper may be used.

The printing apparatus 1 of the present embodiment includes a pair of transport rollers, not shown, inside the casing 2 for transporting a medium in the transport direction a on a transport path of the medium, which is configured by a medium support unit 5 or the like for supporting the medium. Further, a heater, not shown, capable of heating the medium supported by the medium support portion 5 is provided below the medium support portion 5. As described above, the printing apparatus 1 of the present embodiment includes, as the heating portion, a heater capable of heating the medium, but may include, as the heating portion, an infrared heater or the like provided at a position facing the medium support portion 5.

The casing 2 includes a head 4 and a carriage 6 inside, the head 4 is an ink jet head that ejects ink from a plurality of nozzles, not shown, to perform printing, and the carriage 6 is mounted with the head 4 and is capable of reciprocating in the scanning direction B. As described above, the head 4 is configured to be capable of performing printing by ejecting ink from nozzles, not shown, to a medium being conveyed while reciprocating in the scanning direction B intersecting the conveying direction a. By providing the head 4 having such a configuration, the printing apparatus 1 of the present embodiment can form a desired image on a medium by repeating an operation of conveying the medium in the conveying direction a by a predetermined amount (one stroke (pass) amount) and an operation of ejecting ink while moving the head 4 in the scanning direction B in a state where the medium is stopped.

Further, although the printing apparatus 1 of the present embodiment is a so-called serial printer that alternately repeats conveyance of a medium and scanning of the head 4 to perform printing, it may be a so-called line printer that uses a line head in which nozzles are formed in a line shape along the width direction of the medium and continuously performs printing while continuously conveying the medium. Further, a printing unit other than the inkjet head, such as a transfer printing unit, may be provided.

Further, a winding shaft 10 capable of winding the medium in a roll shape is provided on the downstream side of the head 4 in the conveyance direction a of the medium. Further, between the end portion on the downstream side in the conveyance direction a of the medium in the medium support 5 and the take-up reel 10, a contact portion that is in contact with the medium is provided extending in the scanning direction B, and a tension lever 9 that can apply a desired tension to the medium is provided.

Since the printing apparatus 1 of the present embodiment is a large-sized device, when moving the printing apparatus 1, the printing apparatus 1 is moved in a lifted state by using a lifting device such as a forklift. Therefore, the printing apparatus 1 of the present embodiment is a structure suitable for lifting by using the lifting device. Therefore, the structure will be described in detail below with reference to fig. 2 to 5.

As shown in fig. 2, the printing apparatus 1 of the present embodiment has two U-shaped reinforcing members 20A as the reinforcing members 20 attached to a lifting surface 25, which is a surface on the-Z direction side in the case 2. In addition, in the printing apparatus 1 of the present embodiment, two leg portions 13a and a connecting portion 13b connecting the two leg portions 13a are provided. The two leg portions 13a and the connecting portion 13b connecting the two leg portions 13a are detachable from the case portion 2, and the two leg portions 13a and the connecting portion 13b are detachable from the case portion 2 at the time of packaging or the like.

In addition, as shown in fig. 2, the printing apparatus 1 of the present embodiment is provided with

convex portions

11a and 11b that are convex in the-Z direction on the lifting surface 25. Electrical devices such as substrates are formed on the

convex portions

11a and 11b, and when the

convex portions

11a and 11b are biased, the convex portions may be damaged. Therefore, the U-shaped reinforcing member 20A as the reinforcing member 20 of the present embodiment is substantially U-shaped as shown in fig. 3, and is disposed so as to straddle the

convex portions

11a and 11b as shown in fig. 2. The electric device corresponds to, for example, a substrate, a cable, a cover member for covering them, and the like.

The two U-shaped reinforcing members 20A have the same shape, and as shown in fig. 3 and 4, have two upper surfaces 202, two side surfaces 203 each connected to the respective upper surfaces 202, and a lower surface 201 connected to the two side surfaces 203. Further, each of the two U-shaped reinforcing members 20A sandwiches the two upper surfaces 202 between the lifting surface 25 and the rails 24 by the two rails 24 attached to the lifting surface 25 and extending in the X-axis direction. Both U-shaped reinforcing members 20A are configured to be movable on the lifting surface 25 along the X-axis direction.

To summarize here, the U-shaped reinforcing member 20A of the present embodiment is a reinforcing member 20 attached to the printing apparatus 1, and can be disposed at a position where the self-weight of the printing apparatus 1 acts when the printing apparatus 1 is lifted by the lifting device. A lower surface 201, which is a first surface, is in contact with the lifting device, and an upper surface 202, which is a second surface opposite to the lower surface 201, is in contact with the lifting surface 25 of the printing device 1. Since the U-shaped reinforcing member 20A of the present embodiment has such a configuration, when the printing apparatus 1 is lifted by the lifting device, the printing apparatus 1 can be reinforced, and the printing apparatus 1 can be prevented from being damaged.

In addition, although the raised surface 25 of the printing apparatus 1 is provided with the

convex portions

11a and 11b as the electrical devices as described above, the U-shaped reinforcing member 20A of the present embodiment is attached to the raised surface 25 in such a manner that the

convex portions

11a and 11b are positioned between the lower surface 201 and the upper surface 202. Therefore, the U-shaped reinforcing member 20A of the present embodiment can protect the

convex portions

11a and 11b, and can suppress the

convex portions

11a and 11b from being damaged by the force applied to the

convex portions

11a and 11b.

In the printing apparatus 1 of the present embodiment, two or more reinforcing members 20 having the above-described structure are attached to the lifting surface 25, as will be described from the perspective of the printing apparatus. Therefore, in the printing apparatus 1 of the present embodiment, when the printing apparatus 1 is lifted by the lifting device, the printing apparatus 1 can be reinforced by the reinforcing member 20 at a plurality of places, and the printing apparatus 1 can be brought into contact with the lifting device at a plurality of places, so that the printing apparatus 1 can be lifted in a balanced manner, and the damage of the printing apparatus 1 can be suppressed.

Further, as described above, the printing apparatus 1 of the present embodiment can move the reinforcing member 20 along the lifting surface 25. For example, it is conceivable that the width of the lifting portions such as the width of the forks differs depending on the type of forklift used and the like in the portion of the lifting device such as the forks of the forklift for lifting the printing apparatus 1. However, even when the widths of the raised portions are various, the printing apparatus 1 of the present embodiment can appropriately cope with the above-described problem by changing the arrangement of the reinforcing member 20 according to the widths.

Further, in the printing apparatus 1 of the present embodiment, each of the plurality of reinforcing members 20 can be individually moved to an arbitrary position in the X-axis direction. Therefore, for example, even when the position of the center of gravity of the printing apparatus 1 changes depending on the state of the printing apparatus 1 such as the amount of ink in the ink cartridge, the position of each reinforcing member 20 can be appropriately adjusted by changing the position of the center of gravity.

On the other hand, instead of the structure in which each of the plurality of reinforcing members 20 can be individually moved to an arbitrary position, a structure in which the second reinforcing member among the plurality of reinforcing members 20 can be moved so as to be interlocked with the movement of the first reinforcing member as the first reinforcing member among the plurality of reinforcing members 20 is moved may be employed. For example, when the reinforcing member 20 on the + X direction side is moved by a desired distance to the + X direction side, the reinforcing member 20 on the-X direction side is also moved by the desired distance to the-X direction side in conjunction therewith. With such a configuration, for example, in the case of a configuration in which the center of gravity position of the printing apparatus 1 is difficult to change, the arrangement of the reinforcing member 20 can be changed easily and in a well-balanced manner in accordance with the width of the portion of the lifting device that lifts the printing apparatus 1.

For example, when the reinforcing member 20 on the + X direction side is moved by a desired distance to the + X direction side, the reinforcing member 20 on the-X direction side may be moved by the desired distance to the + X direction side in an interlocking manner in the same manner. With such a configuration, for example, when the center of gravity position of the printing apparatus 1 changes, one reinforcing member 20 can be moved without changing the interval between the reinforcing members 20 in the X-axis direction, and the arrangement of the other reinforcing members 20 can be moved in conjunction therewith.

Further, when the reinforcing member 20 on the + X direction side is moved by a desired distance to the + X direction side, the reinforcing member 20 on the-X direction side is also moved by the desired distance to the-X direction side in conjunction therewith, and for example, a mechanism similar to that used for a medium loading portion of a conventional printer, facsimile apparatus, or the like and used for a pressing portion of a medium end portion that can be changed in position in accordance with an end portion of a medium having various widths and whose center position is maintained can be employed. Further, when the reinforcing member 20 on the + X direction side is moved by a desired distance to the + X direction side, the reinforcing member 20 on the-X direction side is also moved by the desired distance in conjunction with the same, and for example, a mechanism in which the reinforcing members 20 are connected to each other by a rod-like member or the like extending in the X axis direction can be employed.

In addition, in the printing apparatus 1 of the present embodiment, as shown in fig. 4, the stopper portions 24a are formed at both ends of the rail 24, and the stopper portions 24a function as restricting portions that restrict movement of the reinforcing member 20 so that the reinforcing member 20 does not fall off. Therefore, the printing apparatus 1 of the present embodiment can prevent the reinforcing member 20 from being detached from the printing apparatus 1 due to excessive movement or the like caused by detachment from the desired movement range

Further, the printing apparatus 1 of the present embodiment is coated with the lubricant at the contact portions with the reinforcing member 20 in the lifting surface 25 and the rail 24. In this way, it is preferable to provide a lubrication mechanism between the lifting surface 25 and the reinforcing member 20, which lubricates the movement of the reinforcing member 20 relative to the lifting surface 25. This is to enable the reinforcing member 20 to move relative to the printing apparatus 1 in a lubricated manner. The structure of the lubricating mechanism is not particularly limited, and for example, a structure in which a lubricant is applied between the lifting surface 25 and the reinforcing member 20 as in the present embodiment, or a structure in which a bearing mechanism is provided between the lifting surface 25 and the reinforcing member 20, or the like can be employed.

As described above, the reinforcing member 20 in the printing apparatus 1 according to the present embodiment is the U-shaped reinforcing member 20A having a substantially U-shape. If explained from another perspective, there is a lower surface 201 as a first surface, an upper surface 202 as a second surface, and a side surface 203 as a third surface that is connected to the lower surface 201 and the upper surface 202 and intersects with the lower surface 201 and the upper surface 202. With such a configuration, the reinforcing member 20 having high rigidity can be configured with a simple configuration. However, the reinforcing member 20 is not limited to the structure of the U-shaped reinforcing member 20A having a substantially U-shape. Further, as an example of the structure having the lower surface 201 as the first surface, the upper surface 202 as the second surface, and the side surface 203 as the third surface which is connected to the lower surface 201 and the upper surface 202 and intersects with the lower surface 201 and the upper surface 202, there is a substantially H-shape, a substantially Z-shape, or the like as shown by laying H upside down, in addition to a substantially U-shape.

Example 2

Hereinafter, the printing apparatus 1 of embodiment 2 in which the reinforcing member 20 is not substantially U-shaped but substantially H-shaped will be described with reference to fig. 5. The substantially U-shaped and the substantially H-shaped mean that the cross-sectional shape of the filter has a portion having a substantially U-shaped or a substantially H-shaped cross-section. Although fig. 5 shows only one H-shaped reinforcing member 20B as the reinforcing member 20, actually, one H-shaped reinforcing member 20B having the same structure is provided on the back side of the H-shaped reinforcing member 20B shown in fig. 5, and two H-shaped reinforcing members 20B are provided in the printing apparatus 1 of embodiment 2. The configuration of the printing apparatus 1 according to embodiment 2 other than the shape of the reinforcing member 20 is the same as that of the printing apparatus 1 according to embodiment 1. The same reference numerals are used for the components common to the above embodiments, and detailed description is omitted.

As shown in fig. 5, in the printing apparatus 1 of the present embodiment, the reinforcing member 20 is an H-shaped reinforcing member 20B having a substantially H shape as shown by laying down H. The H-shaped reinforcing member 20B also has a lower surface 201 as a first surface, an upper surface 202 as a second surface, and a side surface 203 as a third surface that is connected to the lower surface 201 and the upper surface 202 and intersects with the lower surface 201 and the upper surface 202, similarly to the U-shaped reinforcing member 20A. With such a configuration, the reinforcing member 20 having high rigidity can be configured with a simple configuration.

Similarly to the U-shaped reinforcing member 20A, the H-shaped reinforcing member 20B is configured such that a lower surface 201, which is a first surface, comes into contact with the lifting device and an upper surface 202, which is a second surface on the opposite side of the lower surface 201, comes into contact with the lifting surface 25 of the printing apparatus 1. Since the H-shaped reinforcing member 20B of the present embodiment has such a configuration, the printing apparatus 1 can be reinforced and damage to the printing apparatus 1 can be suppressed when the printing apparatus 1 is lifted by the lifting device, similarly to the U-shaped reinforcing member 20A.

The present invention is not limited to the above-described embodiments, and can be implemented by various configurations without departing from the scope of the invention. For example, in order to solve a part or all of the above-described problems or achieve a part or all of the above-described effects, technical features in the embodiments corresponding to technical features in the respective aspects described in the contents of the present invention may be appropriately replaced or combined. Note that, unless the technical features are described as essential in the present specification, they can be deleted as appropriate.
