Summary of the Invention

Problems to be Solved by the Invention

[0004] The inventors of the present invention conceived that the amount of plastic used can be reduced by replacing the printing directly on the surface of the barrel using ink without using a plastic label. However, in order to print directly on the surface of the barrel using ink without using a plastic label for all barrels during the manufacturing process, a printing system having a capacity equal to or greater than the production capacity when using the current plastic labels is required. Furthermore, the printing system is assumed to be introduced into an existing manufacturing line, and it is necessary to develop it in a space-saving and low-cost manner as much as possible. When printing directly on the surface of the barrel using ink without using a plastic label on the entire circumference of a large barrel on the manufacturing line, a series of steps such as (1) stopping the large barrel at a fixed position during transportation, (2) gripping the stopped large barrel, (3) lifting the large barrel, (4) printing while rotating the lifted large barrel, (5) lowering the large barrel to the conveyor after printing, and (6) discharging the large barrel from the printing system are required to operate continuously in a printing system. When combining these operations, there was a problem that the time required for printing per barrel (hereinafter sometimes referred to as tact time) did not reach the tact time when using the current plastic labels.

[0005] The present disclosure aims to provide a barrel printing system and a barrel printing method that can shorten the tact time and achieve a production capacity equal to or greater than the production capacity when using the current plastic labels.

Embodiment for Carrying Out the Invention

[0023] Embodiments of the present invention will be described with reference to the drawings, but the present invention is not construed as being limited to these descriptions. As long as the effects of the present invention are achieved, the embodiments may be variously modified.

[0024] Fig. 1 is a schematic front view showing an example of a barrel printing system according to the present embodiment. The barrel printing system 1 according to the present embodiment is a barrel printing system for printing on the outer surface of the barrel 100. The barrel printing system 1 includes a lifting and rotating device 10 for the barrel 100 and a printing device 20 for printing on the side surface of the barrel 100. The lifting and rotating device 10 includes a support component 14 for supporting the barrel 100 and raising the barrel, a pressing component 16 for restricting the upward movement of the barrel 100 to a predetermined amount, and a rotating mechanism for rotating the barrel 100 about the central axis O of the barrel 100.

[0025] The bottle printing system 1 is a system in which the printing device 20 performs printing on the side surface of the bottle 100 while lifting the bottle 100 from the conveying surface of the conveying device 17 and rotating the bottle 100 about the central axis O of the bottle 100. The central axis O of the bottle 100 is an axis extending in the vertical direction of the bottle 100, and is, for example, the axis of the spear valve 113. In FIG. 1, as an example, the form in which the bottle 100 is supplied to the bottle printing system 1 with the spear valve 113 facing downward is shown. However, the present invention is not limited to this, and in FIG. 1, the bottle 100 may be supplied to the bottle printing system 1 in a state where the top and bottom of the bottle 100 are reversed, that is, with the spear valve 113 facing upward. The bottle printing system 1 may be incorporated in-line into an existing bottling system for filling the bottle with a content such as an alcoholic beverage such as beer or a soft drink water. The existing bottling system is, for example, a bottling device for a returnable bottle that has been collected, and is a system in which, for example, an external washer, an internal washer, and a filling machine are laid out on the conveying path. When the bottle printing system 1 is incorporated in-line into such a bottling system, the bottle printing system 1 is preferably laid out on the conveying path between the internal washer and the filling machine.

[0026] In FIG. 1, as an example, a form is shown in which the first skirt wall 101 and the second skirt wall 102 supply a metal barrel 100 made of stainless steel or the like to the barrel printing system 1. However, in this embodiment, the type of barrel is not limited to this. In this embodiment, the barrel includes, for example, a barrel 100 made of metal such as stainless steel with a first skirt wall 101 and a second skirt wall 102 as exemplified in FIG. 1, and a barrel 200 in which at least the outer surface of either or both of the first skirt wall 201 and the second skirt wall 202 is made of rubber and has a through hole as exemplified in FIG. 16, and a barrel in which at least the outer surface of either or both of the first skirt wall 201 and the second skirt wall 202 in the barrel 200 exemplified in FIG. 16 is made of plastic or metal. Also, the barrel 100 may be a returnable container or a one-way container. The content is not particularly limited, but for example, it is beer, sparkling wine or other carbonated alcoholic beverages, or soft drink water. The capacity of the barrel 100 is, for example, 7 to 20 L is the mainstream, but it is not particularly limited in the present invention.

[0027] FIG. 3 is a schematic partial cross-sectional view showing an example of a barrel having a skirt wall with a rim. The barrel 100 includes, for example, as shown in FIG. 3, a barrel body 110, a first skirt wall 101, a second skirt wall 102, and rims 101a, 102a provided on either or both of the first skirt wall 101 and the second skirt wall 102 and protruding inward in the radial direction of the barrel 100. The barrel body 110, the first skirt wall 101, and the second skirt wall 102 are preferably made of metal such as stainless steel. The barrel body 110 has a first end wall 111 having a spear valve 113, a second end wall 112 facing the first end wall 111, and a side wall 114 connecting the first end wall 111 and the second end wall 112, and the internal space serves as a storage space for the content. The spear valve 113 serves as both a filling port and a pouring port for the content. The first skirt wall 101 is a cylindrical body connected in the direction in which the first end wall 111 is provided on the side wall 114. The second skirt wall 102 is a cylindrical body connected in the direction in which the second end wall 112 is provided on the side wall 114.

[0028] The rims 101a and 102a are annular protrusions. In FIG. 3, as an example, the form in which the rims 101a and 102a are provided on both the first skirt wall 101 and the second skirt wall 102 is shown. However, the present embodiment is not limited to this, and the form in which the rim 101a is provided only on the first skirt wall 101 or the form in which the rim 102a is provided only on the second skirt wall 102 may be used. The rims 101a and 102a may be provided at the end of the first skirt wall 101 and / or the end of the second skirt wall 102, or the rims 101a and 102a may be provided on the peripheral wall of the first skirt wall 101 and / or the peripheral wall of the second skirt wall 102. When the rims 101a and 102a are provided at the end of the first skirt wall 101 and / or the end of the second skirt wall 102, as shown in FIG. 3, the rims 101a and 102a curve the ends of the skirt walls 101 and 102 inward over the entire circumference, and the curved portion is a tubular body having a substantially circular cross section. Further, when the rims 101a and 102a are provided on the peripheral wall of the first skirt wall 101 and / or the peripheral wall of the second skirt wall 102, the rims 101a and 102a are ribs that project inward over the entire circumference of the peripheral walls of the skirt walls 101 and 102. The rims 101a and 102a are, for example, portions that serve as gripping portions for hooking fingers on the rims 101a and 102a and carrying the barrel 100 made of metal skirt walls 101 and 102. Among these, as shown in FIG. 3, it is preferable that the rims 101a and 102a are provided at the end of the first skirt wall 101 and / or the end of the second skirt wall 102, and the ends of the skirt walls 101 and 102 are curved inward over the entire circumference, and the curved portion is a tubular body having a substantially circular cross section. Thereby, since the rims 101a and 102a can be supported by the support parts 14 described later, the barrel 100 can be supported more reliably.

[0029] The lifting and rotating device 10 preferably includes, for example, as shown in FIG. 1, a base body 12, a rotating mechanism of the base body 12, a lifting mechanism 13 of the base body 12, a support component 14 attached to the base body 12, a driving mechanism for driving the support component 14 with respect to the base body 12, and a pressing component 16 attached to the base body 12. The base body 12 is, for example, a plate-shaped component and is rotatably attached to the device main body 11 of the lifting and rotating device 10 by a rotating mechanism. The rotating mechanism is a mechanism that applies a driving force to rotate the base body 12 with respect to the device main body 11, and is not particularly limited. For example, it is a servo motor, and under the control of a control device, it rotates and stops the rotation of the base body 12. The lifting mechanism 13 is a mechanism that operates the base body 12 up and down with respect to the device main body 11, and is not particularly limited. For example, it is a piston cylinder, and under the control of a control device, it lowers or raises the base body 12. The lifting mechanism 13 moves the support component 14 and the pressing component 16 to a predetermined position near the upper end of the barrel 100. The size of the stroke amount of the lifting mechanism 13 can correspond to the size (height difference) of the barrel 100. The support component 14 is a component that supports and raises the barrel 100 at the same time. The driving mechanism is a mechanism that drives the support component 14 to support and raise the barrel 100 at the same time, and is not particularly limited. For example, it is an air cylinder or a hydraulic cylinder. The pressing component 16 is a component that restricts the barrel 100 from approaching to only a predetermined distance when the barrel 100 approaches the base body 12.

[0030] The printing device 20 may be any device that can print on the side surface of the barrel 100 and is not particularly limited. However, in the barrel printing system 1 according to the present embodiment, the printing device 20 is an inkjet printer having an inkjet head, and the inkjet head is preferably directed toward the side surface of the barrel 100 lifted by the lifting and rotating device 10. By using an inkjet printer as the printing device 20, it is not necessary to make a large-scale layout change to the existing equipment, and printing can be realized by making a small-scale change in detail such as incorporating the printing device 20 and the lifting and rotating device 10. The printing device 20 is preferably a drop-on-demand full-color inkjet printer. By using a drop-on-demand full-color inkjet printer as the printing device 20, it is possible to have a decorative property equivalent to that of a plastic label. The side surface of the barrel 100 that becomes the printing area includes, for example, the side surface of the barrel body 110, the side surface of the first skirt wall 101, and the side surface of the second skirt wall 102. The printing area may be provided only on a part of the circumferential direction of the side surface of the barrel 100, or may be provided intermittently or continuously over the entire circumferential direction of the side surface of the barrel 100. The printing is preferably performed continuously or intermittently over the entire circumference of the side surface of the barrel body 110, for example.

[0031] When the cask 100 is conveyed to a predetermined position directly below the elevating and rotating device 10 as shown in FIG. 1, the elevating and rotating device 10 moves the elevating mechanism 13 downward to move the support part 14 and the pressing part 16 closer to the predetermined position of the cask 100. Next, the drive mechanism moves the support part 14 in a direction approaching the cask 100, so that the support part 14 supports and lifts the cask 100 at the same time. As a result, the cask 100 is lifted from the conveying surface of the conveying device 17. The pressing part 16 restricts the upward movement of the lifted cask 100. As a result, the cask 100 is clamped between the support part 14 and the pressing part 16, and the base body 12 and the cask 100 are integrated. Then, the cask 100 rotates by the rotation of the base body 12 by the rotation mechanism. While the cask 100 is rotating, the printing device 20 discharges ink toward the side surface of the cask 100. As a result, printing is performed on the outer surface of the cask 100. When the printing is completed, the drive device moves the support part 14 in a direction away from the cask 100, so that the support of the cask 100 by the support part 14 is released, and the cask 100 is returned to the conveying surface of the conveying device 17.

[0032] FIG. 15 is a schematic diagram showing an example of the discharging mechanism. As shown in FIGS. 1 and 15, the keg printing system 1 according to the present embodiment preferably further includes a discharging mechanism 18 that moves the keg 100 toward the downstream of the conveying path at a speed faster than the conveying speed of the conveying device 17 for the keg 100. By providing the discharging mechanism 18, the keg 100 can be continuously printed, so that the tact time can be further shortened. It is only necessary to be able to move the keg 100 at high speed toward the downstream of the conveying path, and it is not particularly limited in the present embodiment. For example, as shown in FIG. 1, it is preferably a mechanism that hooks a rod 18a on the skirt wall 101 of the keg 100 and sends it out. As a specific example of such a mechanism, for example, the discharging mechanism 18 includes a rod 18a disposed directly below the lifting and rotating device 10 and below the conveying device 17, an up-and-down mechanism that causes the rod 18a to protrude from below the conveying surface of the conveying device 17 to above the conveying surface, and a reciprocating mechanism that reciprocates the rod 18a. The rod 18a is not particularly limited, but is, for example, a rod-shaped member. The up-and-down mechanism is not particularly limited, but is, for example, a piston cylinder. The reciprocating mechanism is not particularly limited, but is, for example, an air cylinder or a hydraulic cylinder. The discharging mechanism 18 operates as follows to discharge the keg 100. When the keg 100 finishes printing and is returned onto the conveying surface of the conveying device 17, the up-and-down mechanism causes the rod 18a to protrude above the conveying surface, and the tip of the rod 18a protrudes into the space surrounded by the skirt wall 101 (the first skirt wall in FIG. 1) disposed on the lower side of the skirt walls 101 and 102 of the keg 100. In this state, the reciprocating mechanism moves the rod 18a toward the downstream of the conveying path at a speed faster than the conveying speed of the conveying device 17. As a result, the skirt wall 101 is pushed out downstream of the conveying path by the rod 18a, so that the keg 100 moves toward the downstream of the conveying path. When the discharging of the keg 100 is completed, the reciprocating mechanism moves the rod 18a toward the upstream of the conveying path to discharge the next keg 100.

[0033] The barrel printing system 1 according to this embodiment preferably further includes a guiding mechanism for guiding the barrel 100 conveyed by the conveying device 17 directly below the lifting and rotating device, and a positioning mechanism for the barrel 100. The guiding mechanism is, for example, a guiding plate disposed on the conveying device 17. The positioning mechanism is, for example, a stopper cylinder that protrudes and retracts from both sides of the conveying device 17 to clamp the side surface of the barrel 100. The conveyed barrel 100 moves along the guiding mechanism and is guided to a predetermined position on the conveying surface of the conveying device 17. Then, directly below the lifting and rotating device 10, the barrel 100 stops at a predetermined position by the positioning mechanism. Thereafter, as described above, the barrel 100 is supplied to the lifting and rotating device 10 for printing. The control method of the barrel printing system 1 according to this embodiment is not particularly limited, and a known control method may be adopted. The known control method is, for example, a method in which the position of the barrel 100 is detected by a barrel detection sensor such as a photoelectric sensor, and a control device such as a computer having a microprocessor controls the operation of each element of the barrel printing system 1 based on the detection signal from the barrel detection sensor.

[0034] So far, the overall configuration of the barrel printing system 1 according to this embodiment has been described. However, the barrel printing system 1 according to this embodiment includes the following forms depending on the difference in the method of supporting the barrel 100 by the supporting parts. The barrel printing system 1 according to this embodiment includes a form (first embodiment) in which the skirt walls 101, 102 of the barrel 100 have rims 101a, 102a and the supporting parts 14 support the rims 101a, 102a of the barrel 100, a form (second embodiment) in which the skirt walls 101, 102 of the barrel 100 are made of metal and the supporting parts 14 fit and support parts other than the rims 101a, 102a of the barrel 100, and a form (third embodiment) in which at least the outer surface of the skirt walls 201, 202 of the barrel 200 is made of rubber or plastic or metal as shown in FIG. 16, and has through holes, and supports the through holes provided in the skirt walls 201, 202 or fits and supports parts other than the skirt walls 201, 202. The first to third embodiments include the overall configuration of the barrel printing system 1 described so far as a common configuration. Therefore, hereinafter, the first to third embodiments will be described centering on the characteristic configurations.

[0035] (First Embodiment) First, the first embodiment will be described. FIGS. 4 to 6 are schematic views for explaining the support and lifting of the barrel by the support claws. In the barrel printing system 1 according to the first embodiment, as shown in FIG. 3, the barrel 100 includes a first skirt wall 101, a second skirt wall 102, and rims 101a, 102a provided on either one or both of the first skirt wall 101 and the second skirt wall 102 and protruding radially inward of the barrel 100. The support component 14 includes a form of supporting the rim 102a as shown in FIGS. 4 to 6.

[0036] In FIG. 3, as an example, a form in which the rims 101a, 102a are provided on both the first skirt wall 101 and the second skirt wall 102 is shown. However, the present embodiment is not limited to this, and at least it is preferably provided on the skirt wall (the second skirt wall in FIGS. 4 to 6) that becomes the upper side when the barrel 100 is supplied to the elevating and rotating device 10. That is, when the barrel 100 is supplied to the elevating and rotating device 10 with the second end wall 112 facing up and the first end wall 111 facing down as shown in FIGS. 4 to 6, the rim 102a is preferably provided on at least the second skirt wall 102. When the barrel 100 is supplied to the elevating and rotating device 10 with the first end wall 111 facing up and the second end wall 112 facing down, the rim 101a is preferably provided on at least the first skirt wall 101.

[0037] In the barrel printing system 1 according to the first embodiment, as shown in FIG. 1, the elevating and rotating device 10 further includes a base body 12, a rotation mechanism of the base body 12, and an elevating mechanism 13 of the base body 12. The support component 14 has, as shown in FIG. 4, a slide component 31 attached to the base body 12 and moving in the horizontal direction, and a support claw 30 interlocking with the slide component 31. The support claw 30 is inclined downward toward the outside in the radial direction of the barrel 100, and as shown in FIGS. 5 and 6, it preferably moves toward the outside in the radial direction of the barrel 100 while contacting the rim 102a. Since the barrel 100 is supported and lifted simultaneously by the simple operation of the parallel movement of the support claw 30, the tact time can be further shortened.

[0038] The slide component 31 is, for example, a component that translates with respect to the base body 12 and moves horizontally along the rail 15, for example. The horizontal direction preferably coincides with the radial direction of the barrel 100. The slide component 31 preferably has, for example, a sliding portion 31a slidably fitted to the rail 15 and a fixing portion 31b for fixing the support claw 30. In FIG. 4, the slide component 31 is shown as an L-shaped component as an example, but the present embodiment is not limited thereto. The rail 15 has a groove for slidably fitting the slide component 31 and a drive mechanism for sliding the slide component 31. The drive mechanism is not particularly limited, but is, for example, an air cylinder.

[0039] The support claw 30 is a plate-like component or a rod-like component and is inclined downward toward the outside in the radial direction of the barrel 100 in a state of being attached to the base body 12 via, for example, the slide component 31. Being inclined downward toward the outside in the radial direction of the barrel 100 means being inclined such that the distance between the contact portion 30a with respect to the rim 102a of the support claw 30 and the horizontal plane passing through the sliding surface of the rail 15 increases as it goes toward the outside in the radial direction of the barrel 100.

[0040] An operation example of the barrel printing system 1 according to the first embodiment will be described. When the drive mechanism slides the slide component 31 along the rail 15 as indicated by the arrow R1 in FIG. 4, the support claws 30 move together with the slide component 31. As shown in FIG. 5, the drive mechanism moves the slide component 31 to a position where the contact portion 30a of the support claws 30 contacts the upper rim (the rim of the second skirt wall 102 in FIG. 5) 102a of the rims 101a and 102a of the barrel 100, and further moves the barrel 100 radially outward while the support claws 30 contact the rim 102a as indicated by the arrow R1 in FIG. 5. Then, as shown in FIG. 6, as the rim 102a slides along the contact portion 30a of the support claws 30 with the movement of the support claws 30, the barrel 100 is supported by the support claws 30 and lifted from the position of the barrel indicated by the broken line to the position of the barrel 100 indicated by the solid line in FIG. 6. Such a movement in which the support component 14 grips the barrel 100 and at the same time raises the barrel 100 contributes to shortening the tact time. The upward movement of the barrel 100 lifted by the support component 14 is restricted when the upper end of the upper skirt wall (the second skirt wall in FIG. 6) 102 contacts the lower surface of the pressing component 16. Then, the rim 102a is clamped by the support claws 30 of the support component 14 and the pressing component 16, and the base 12 and the barrel 100 are integrated, and the barrel 100 rotates by the operation of the rotation mechanism of the base 12. The movement in which the support component 14 supports and grips the rim 102a at the contact portion and at the same time raises the barrel 100 not only contributes to shortening the tact time, but also can make the central axis O of the barrel 100 and the rotation axis by the rotation mechanism of the base 12 more coincident, thus contributing to improving the printing accuracy. In FIG. 6, as an example, a form in which the support claws 30 support the side surface of the rim 102a is shown. The support claws 30 preferably support the lower half portion of the side surface of the rim 102a. Also, the support claws 30 may support the lower surface of the rim 102a.

[0041] FIG. 2 is a schematic diagram for explaining the positional relationship between the support claws and the pressing parts. In FIG. 2, for the sake of illustration, the support claws 30 are shown instead of the support parts 14. The number of the support parts 14 is not particularly limited and may be only one or two or more. In the first embodiment, it is more preferable that the support parts 14 are two or more. By having two or more support parts 14, in addition to the effect of shortening the tact time, the positioning effect and the centering effect of the barrel 100 can be obtained. In this specification, centering means making the central axis O of the barrel 100 coincide with the rotation axis by the rotation mechanism of the base body 12. In FIG. 2, a form in which there are three support parts 14 is shown as an example, but this embodiment is not limited thereto, and the support parts 14 may be two or four or more. When there are two or more support parts 14, as shown in FIG. 2, it is preferable that the pressing parts 16 are arranged between adjacent support parts 14. Thereby, the rim 102a of the barrel 100 can be more stably clamped in the circumferential direction of the barrel 100 by the support parts 14 and the pressing parts 16.

[0042] In FIG. 6, it is preferable to provide a notch engaging with the rim 102a at the downstream portion in the sliding direction with respect to the rim 102a among the contact portions 30a of the support claw 30. The downstream portion in the sliding direction is preferably the portion where the rim 102a is in contact when the upper end of the skirt wall 102 contacts the pressing part 16 among the contact portions 30a of the support claw 30. More specifically, in FIG. 6, the notch is preferably provided in the portion of the contact portion 30a where the rim 102a is in contact. The notch is a recess provided in the contact portion 30a and into which the rim 102a can engage. By providing the notch, even when there is only one support part 14, after the barrel 100 is lifted, the effect that the rim 102a engages with the notch to more firmly support the barrel 100 can be obtained.

[0043] FIG. 7 is a schematic view showing an example of a preferable shape of the support claw, where (a) is a schematic plan view of the base end of the support claw as viewed from the front, and (b) is a schematic view of the claw tip as viewed from the front. In the barrel printing system 1 according to the first embodiment, it is preferable that the support component 14 makes point contact with the rim 102a (illustrated in FIG. 3, for example). The form in which the support component 14 makes point contact with the rim 102a is not particularly limited. For example, it is preferable that the contact portion 30a of the support claw 30 is a ridge extending along the moving direction of the support claw 30. A ridge refers to a linear convex portion that protrudes with respect to the surrounding portion. By the support component 14 making point contact with the rim 102a, when the barrel 100 is ascending, the support claw 30 can easily slide along the rim 102a, and when the ascent of the barrel 100 is completed, the contact portion 30a such as a ridge bites into the rim 102a, and the effect of being able to firmly support without rattling can be obtained. In FIG. 7, as an example, there are two ridges, and a form in which the support claw 30 makes point contact with the rim 102a at two points is shown. However, the present embodiment is not limited to this, and the number of point contacts may be one point or three or more points.

[0044] In the barrel printing system 1 according to the first embodiment, the support component 14 may be in line contact with the rim. The form in which the support component 14 is in line contact with the rim 102a is not particularly limited. For example, it is a form in which the contact portion 30a of the support claw 30 is planar. At this time, it is preferable that the contact portion 30a has a shape adapted to the circumferential shape of the rim that it contacts when supporting. For example, the shorter the length of the support claw 30 in the width direction, the more planar the contact portion 30a becomes, and the longer the length of the support claw 30 in the width direction, the more convex the contact portion 30a preferably becomes.

[0045] FIG. 8 is a schematic front view showing another example of a preferable shape of the support claws. FIG. 8 shows a form in which the contact portion 30a has seven ridges and the support claws 30 are in point contact with the rim 102a (illustrated in FIG. 3, for example) at seven points. The virtual transverse line L that traverses the support claws 30 through the apexes of the ridges preferably has a shape that conforms to the circumferential shape of the rim that comes into contact when supporting. For example, the shorter the length of the support claws 30 in the width direction, the more the virtual transverse line L becomes a straight line shape, and the longer the length of the support claws 30 in the width direction, the more preferably the virtual transverse line L becomes a mountain-like shape.

[0046] FIG. 9 is a schematic diagram for explaining the support and lifting of the barrel by the rotating component. The barrel printing system shown in FIG. 9 is a system in which, in the barrel printing system shown in FIG. 1, the support component is changed from a component having support claws 30 to a rotating component 40, and the basic configuration other than the support component is the same as that of the barrel printing system shown in FIG. 1. In the barrel printing system 1 according to the first embodiment, the elevating and rotating device 10 further includes a base body 12, a rotating mechanism of the base body 12, and an elevating mechanism 13 of the base body 12. The support component 14 is a rotating component 40 that is attached to the base body 12 and rotates. The rotating component 40 preferably rotates from the inside of the barrel 100 toward the rim 102a to push up the rim 102a, and more preferably pushes up the boundary portion 40a between the rim 102a and the second skirt wall 102. By the simple operation of the rotating component 40 rotating, the barrel 100 can be supported and lifted at the same time, so that the tact time can be further shortened. The rotating component 40 preferably contacts, in addition to the boundary portion 40a between the rim 102a and the second skirt wall 102, the inner edge 40b in the radial direction of the rim 102a. Thereby, the positioning effect and the centering effect of the barrel 100 can be obtained.

[0047] The rotating component 40 is preferably a component having a hook at its tip, for example. The rotating component 40 may be a rod-shaped component or a plate-shaped component. The rotating component 40 is rotatably attached to the base body 12, for example. When the rotating component 40 rotates from the inner side in the radial direction of the barrel 100 toward the outer side in the radial direction, the rotating component 40 contacts, for example, the boundary portion 40a between the rim 102a and the second skirt wall 102, and by further continuing to rotate, the rotating component 40 pushes up the boundary portion 40a between the rim 102a and the second skirt wall 102. As a result, the barrel 100 is supported by the rotating component 40 and at the same time rises. The operation of the barrel 100 after rising is the same as that in the form in which the supporting component 14 has the supporting claws 30. When the rotating component 40 is a rod-shaped component, the rotating component 40 makes point contact with the boundary portion 40a between the rim and the second skirt wall 102. When the rotating component 40 is a plate-shaped component and the tip of the hook is curved in accordance with the circumferential shape of the rim, the rotating component 40 makes line contact with the boundary portion 40a between the rim and the second skirt wall 102. Also, when the rotating component 40 is a plate-shaped component and the tip of the hook has a ridge as shown in FIG. 8, the rotating component 40 makes point contact with the rim.

[0048] (Second Embodiment) Next, the second embodiment will be described. The barrel printing system according to the second embodiment has the same basic configuration as the barrel printing system 1 according to the first embodiment, except that the method of support by the support component 14 is different. For this reason, the description will focus on the different configurations, and the description of the common configurations may be omitted.

[0049] In the bottle printing system according to the second embodiment, the support component 14 includes a form having a support portion with a shape that fits a part of the bottle 100. Here, "fits" includes a form in which the support component 14 contacts and fits exactly with a part of the bottle 100 without a gap, and a form in which at least a part of the support component 14 contacts and supports a part of the bottle 100. In the bottle printing system according to the second embodiment, the bottle may be the bottle 100 having rims 101a and 102a as shown in FIG. 3, or a bottle without rims 101a and 102a. A bottle without rims 101a and 102a has, for example, a shape in which the first skirt wall 101 and / or the second skirt wall 102 in the bottle 100 shown in FIG. 3 is deformed into a cylindrical shape. The bottle printing system according to the second embodiment can support and lift the bottle 100 regardless of the presence or absence of the rims 101a and 102a, so that the tact time can be shortened.

[0050] In the bottle printing system according to the second embodiment, the support component 14 may be in line contact with the bottle 100 or in surface contact with the bottle 100.

[0051] FIG. 10 is a schematic view showing a first example of a component having a shape adapted to a part of a barrel, where (a) is a schematic front view and (b) is a schematic plan view. The component shown in FIG. 10 is a cup-shaped component 50. The cup-shaped component 50 is, for example, a component having a side wall with a shape of a side surface of a cone, or a comb-shaped component along the side surface of a cone. The comb-shaped component has a shape such that, for example, a part of the side surface of the cup-shaped component 50 is periodically missing in the circumferential direction. When the barrel 100 is supplied to the barrel printing system with the spear valve 113 (shown in FIG. 3, for example) facing downward, the cup-shaped component 50 acts as a support component 14 that supports the barrel 100 from below. When the barrel 100 is supplied to the barrel printing system with the spear valve 113 facing upward, the cup-shaped component 50 acts as a pressing component 16 that presses the barrel 100 from above. The inner wall surface 51a of the cup-shaped component 50 preferably has a side surface shape of a cone or a frustum of a cone, and by a part of the circumferential direction coinciding with the outer circumference of the spear valve 113, it is adapted to the spear valve 113. The side surface of the cup-shaped component 50 has a length such that when the inner wall surface 51a contacts the spear valve 113, the edge 51b of the cup-shaped component 50 contacts the first end wall 111, or may have a length such that when the inner wall surface 51a contacts the spear valve 113, the edge 51b of the cup-shaped component 50 does not contact the first end wall 111. Among these, the side surface of the cup-shaped component 50 preferably has a length such that when the inner wall surface 51a contacts the spear valve 113, the edge 51b of the cup-shaped component 50 contacts the first end wall 111, and more preferably has a shape adapted to the first end wall 111 (shown in FIG. 3, for example) of the barrel 100. Thereby, the cup-shaped component 50 is adapted to the barrel 100 not only by the inner wall surface 51a but also by the edge 51b. By using the cup-shaped component 50 as the support component 14 or the pressing component 16, the centering of the barrel 100 can be achieved. The cup-shaped component 50 makes line contact with the barrel 100 at the inner wall surface 51a and the edge 51b.

[0052] FIG. 11 is a schematic view showing a second example of a component having a shape adapted to a part of a barrel, (a) is a schematic front view, and (b) is a schematic plan view. The component shown in FIG. 11 is an annular component 60. The annular component 60 is, for example, a component in which an annular plate having a shape along the outer surface of the first end wall 11 is attached to the tip of an arm, or a component in which a plate piece having a shape along the outer surface of the first end wall is attached to the tip of an arm, and is more preferably an annular component. Both the annular plate and the plate piece contact the first end wall 111 around the base of the spear valve 113. When the barrel 100 is supplied to the barrel printing system with the spear valve 113 (for example, shown in FIG. 3) facing downward, the annular component 60 acts as a support component 14 that supports the barrel 100 from below, and when the barrel 100 is supplied to the barrel printing system with the spear valve 113 facing upward, the annular component 60 acts as a pressing component 16 that presses the barrel 100 from above. The end face 61 of the annular component 60 preferably has a shape adapted to the first end wall 111 (for example, shown in FIG. 3) of the barrel 100. The annular component 60 may be a continuously annular plate shape in the circumferential direction as shown in FIG. 11, or an intermittent annular plate shape in which a part in the circumferential direction is missing in the annular plate shape shown in FIG. 11. The annular component 60 is in surface contact with the barrel 100 at the end face 61.

[0053] FIG. 12 is a schematic view showing a third example of a component having a shape adapted to a part of a barrel, (a) is a schematic front view, and (b) is a schematic plan view. The component shown in FIG. 12 is a disk-shaped component 70. The disk-shaped component 70 may be a continuous plate shape in the circumferential direction as shown in FIG. 12, or an intermittent plate shape with a part missing in the circumferential direction in the plate shape shown in FIG. 12. The disk-shaped component 70 is more preferably a disk-shaped component. When the barrel 100 is supplied to the barrel printing system with the spear valve 113 (illustrated in FIG. 3, for example) facing upward, the disk-shaped component 70 acts as a support component 14 that supports the barrel 100 from below. When the barrel 100 is supplied to the barrel printing system with the spear valve 113 facing downward, the disk-shaped component 70 acts as a pressing component 16 that presses the barrel 100 from above. The end face 71 of the disk-shaped component 70 preferably has a shape adapted to the second end wall 112 (illustrated in FIG. 3, for example) of the barrel 100. The disk-shaped component 70 is in surface contact with the barrel 100 at the end face 71.

[0054] When the cup-shaped component 50 shown in FIG. 10, the annular component 60 shown in FIG. 11, or the disk-shaped component 70 shown in FIG. 12 acts as the support component 14, the drive mechanisms of these components 50, 60, 70 can adopt, for example, a mechanism similar to the up-and-down mechanism of the discharge mechanism. Further, when the cup-shaped component 50 shown in FIG. 10, the annular component 60 shown in FIG. 11, or the disk-shaped component 70 shown in FIG. 12 acts as the pressing component 16, these components 50, 60, 70 are attached to the base 12 and move up and down together with the base 12 by the lifting mechanism 13 (illustrated in FIG. 1).

[0055] FIG. 13 is a schematic diagram showing an example of a support part and a pressing part when the barrel is supplied to the lifting and rotating device with the first end wall having the spear valve facing downward. (a) shows a form in which the part shown in FIG. 12 is the pressing part, (b) shows a form in which the pressing part shown in FIG. 1 is the pressing part, (c) shows a form in which the part shown in FIG. 10 is the support part, and (d) shows a form in which the part shown in FIG. 11 is the support part. In the barrel printing system according to the second embodiment, the barrel 100 includes a barrel body having a first end wall 111 having a spear valve 113 and a second end wall 112 facing the first end wall 111, and is supplied to the lifting and rotating device 10 (shown in FIG. 1) with the first end wall 111 facing downward.

[0056] As shown in FIG. 13(c), a part of the barrel 100 with which the support part is adapted is preferably at the spear valve 113. Here, the support part adapted to the spear valve 113 is, for example, the inner wall surface 51a of the cup-shaped part 50 shown in FIG. 10 as shown in FIG. 13(c). The inner wall surface 51a of the cup-shaped part 50 supports and at the same time lifts the barrel 100 from below by contacting, for example, the upper edge of the spear valve 113. In addition, a part of the barrel 100 with which the support part is adapted is preferably at the first end wall 111 in addition to the spear valve 113. Here, the support part adapted to the first end wall 111 is, for example, the edge 51b of the cup-shaped part 50 shown in FIG. 10 as shown in FIG. 13(c).

[0057] As shown in FIG. 13(d), a part of the barrel 100 with which the support part is adapted is preferably at the first end wall 111. Here, the support part is, for example, the end face 61 of the annular part 60 shown in FIG. 11 as shown in FIG. 13(d). The end face 61 of the annular part 60 supports and at the same time lifts the barrel 100 from below by contacting the first end wall 111.

[0058] As shown in Fig. 13(a), the pressing component 16 preferably has a portion that fits the second end wall 112. Here, the pressing component 16 is, for example, the disc-shaped component 70 shown in Fig. 12 as shown in Fig. 13(a). By contacting the second end wall 112, the pressing component 16 presses the cask 100 lifted by the supporting component 14 from above to regulate the lifting amount, and at the same time, the central axis O of the cask 100 and the rotation axis by the rotation mechanism of the base 12 can be made to coincide more.

[0059] As shown in Fig. 13(b), the pressing component 16 preferably presses the upper edge of the second skirt wall 102. The pressing component 16 shown in Fig. 13(b) is, for example, the same as the pressing component 16 shown in Fig. 1 or Fig. 2. By contacting the upper edge of the second skirt wall 102, the pressing component 16 presses the cask 100 lifted by the supporting component 14 from above to regulate the lifting amount.

[0060] When the cask is supplied to the lifting and rotating device with the first end wall having the spear valve facing down, the combination of the supporting component 14 and the pressing component 16 may be appropriately selected and combined from the pressing component 16 shown in (a) and (b) and the supporting component 14 shown in (c) and (d) in Fig. 13, and the present embodiment is not limited to the combination. The combination is not particularly limited. For example, the form in which the supporting component 14 is the cup-shaped component 50 in Fig. 13(c) and the pressing component 16 is the disc-shaped component 70 in Fig. 13(a), the form in which the supporting component 14 is the cup-shaped component 50 in Fig. 13(c) and the pressing component 16 is the pressing component in Fig. 13(b), the form in which the supporting component 14 is the annular component 60 in Fig. 13(d) and the pressing component 16 is the disc-shaped component 70 in Fig. 13(a), or the form in which the supporting component 14 is the annular component 60 in Fig. 13(d) and the pressing component 16 is the pressing component in Fig. 13(b). Among these, the particularly preferred combination is the form in which the supporting component 14 is the cup-shaped component 50 as shown in Fig. 13(c) and the pressing component 16 is the pressing component 16 as shown in Fig. 13(b).

[0061] FIG. 14 is a schematic view showing an example of a support part and a pressing part when a barrel is supplied to a lifting and rotating device with the first end wall having a spear valve facing upward. (a) shows a form in which the part shown in FIG. 10 is a pressing part, (b) shows a form in which the part shown in FIG. 11 is a pressing part, (c) shows a form in which the pressing part shown in 1 is a pressing part, and (d) shows a form in which the part shown in FIG. 12 is a support part. In the barrel printing system according to the third embodiment, the barrel 100 includes a barrel body having a first end wall 111 having a spear valve 113 and a second end wall 112 facing the first end wall 111, and is supplied to the lifting and rotating device 10 (shown in FIG. 1) with the second end wall 112 facing downward.

[0062] As shown in FIG. 14(d), a part of the barrel 100 to which the support part conforms is preferably on the second end wall 112. Here, the support part is, for example, the end face 71 of the disk-shaped part 70 shown in FIG. 12 as shown in FIG. 14(d). The end face 71 of the disk-shaped part 70 supports and lifts the barrel 100 from below by contacting the second end wall 112.

[0063] As shown in FIG. 14(a), the pressing part 16 preferably has a part that conforms to the spear valve 113. Here, the pressing part 16 is, for example, the cup-shaped part 50 shown in FIG. 10 as shown in FIG. 14(a). The cup-shaped part 50 contacts the first end wall 111 to press the barrel 100 lifted by the support part 14 from above to regulate the lifting amount, and at the same time, can make the central axis O of the barrel 100 and the rotation axis by the rotation mechanism of the base 12 more coincident. The pressing part 16 preferably further has a part that conforms to the first end wall 111 in addition to the part that conforms to the spear valve 113. Here, the support part that conforms to the first end wall 111 is, for example, the edge 51b of the cup-shaped part 50 shown in FIG. 10 as shown in FIG. 14(a).

[0064] As shown in FIG. 14(b), the pressing component 16 preferably has a portion that fits the first end wall 111. Here, the pressing component 16 is, for example, the annular component 60 shown in FIG. 11 as shown in FIG. 14(b). By contacting the first end wall 111, the annular component 60 presses the cask 100 lifted by the supporting component 14 from above to regulate the lifting amount, and at the same time, the central axis O of the cask 100 and the rotation axis by the rotation mechanism of the base 12 can be made more coincident.

[0065] As shown in FIG. 14(c), the pressing component 16 preferably presses the upper edge of the first skirt wall 101. The pressing component 16 shown in FIG. 14(c) is, for example, the same as the pressing component 16 shown in FIG. 1 or FIG. 2. By contacting the upper edge of the first skirt wall 101, the pressing component 16 presses the cask 100 lifted by the supporting component 14 from above to regulate the lifting amount.

[0066] When the cask is supplied to the lifting and rotating device with the first end wall having the spear valve facing upward, the combination of the supporting component 14 and the pressing component 16 may be appropriately selected and combined from the pressing component 16 shown in (a), (b), (c) and the supporting component 14 shown in (d) in FIG. 14, and the present embodiment is not limited to the combination. The combination is not particularly limited. For example, the form in which the supporting component 14 is the disk-shaped component 70 in FIG. 14(d) and the pressing component 16 is the cup-shaped component 50 in FIG. 14(a), the form in which the supporting component 14 is the disk-shaped component 70 in FIG. 14(d) and the pressing component 16 is the annular component 60 in FIG. 14(b), or the form in which the supporting component 14 is the disk-shaped component 70 in FIG. 14(d) and the pressing component 16 is the pressing component in FIG. 14(c). Among these, the particularly preferred combination is the form in which the supporting component 14 is the disk-shaped component 70 as shown in FIG. 14(d) and the pressing component 16 is the cup-shaped component 50 as shown in FIG. 14(a).

[0067] (Third Embodiment) Next, a third embodiment will be described. The barrel printing system according to the third embodiment has the same basic configuration as the barrel printing system 1 according to the first embodiment or the barrel printing system according to the second embodiment, except that the materials of the skirt walls 201 and 202 of the barrel 200 are different. Therefore, the description will focus on the different configurations, and the description of the common configurations may be omitted.

[0068] FIG. 16 is a schematic perspective view showing an example of a barrel in which at least the outer surface of the skirt wall is made of rubber. FIG. 17 is a schematic partial cross-sectional view taken along line A-A of FIG. 16. In the barrel printing system according to the third embodiment, as shown in FIG. 6 or FIG. 7, the barrel 200 includes a first skirt wall 201 and a second skirt wall 202, and at least one or both of the first skirt wall 201 and the second skirt wall 202 have at least an outer surface made of rubber, and includes a form having a peripheral wall 203 and through holes 204 and 205 provided in the peripheral wall 203. In FIG. 16, as an example, a form in which at least one or both of the outer surfaces of the first skirt wall 201 and the second skirt wall 202 of the barrel 200 are made of rubber is shown, but the present embodiment is not limited thereto, and at least one or both of the outer surfaces of the first skirt wall 201 and the second skirt wall 202 of the barrel 200 may be made of plastic or metal in addition to rubber. The type of plastic is not particularly limited, and for example, known industrial plastics such as polypropylene, polyethylene, and polycarbonate can be used. The type of metal is not particularly limited, and for example, it is stainless steel.

[0069] The keg 200 shown in Fig. 16 has the same basic configuration as the keg 100 shown in Fig. 3, except that the materials of the first skirt wall 201 and the second skirt wall 202 are different. The keg body 210 is made of metal such as stainless steel, for example. As shown in Fig. 16 or Fig. 17, the keg 200 may have through holes 204 and 205 in both the first skirt wall 201 and the second skirt wall 202, or only the first skirt wall 201 may have the through hole 204, or only the second skirt wall 202 may have the through hole 205. Also, as shown in Fig. 17, the first skirt wall 201 and the second skirt wall 202 may be entirely made of rubber, plastic, or metal, or may have a core-sheath structure having a sheath material made of rubber, plastic, or metal and a core material covered with the sheath material and having a material different from that of the sheath material. The keg 200 includes forms in which the first skirt wall 201 and / or the second skirt wall 202 do not have a rim and forms having a rim, as shown in Fig. 16 or Fig. 17. When having a rim, the rim may have a structure similar to the rims 101a and 102a provided on the keg 100 shown in Fig. 3, for example.

[0070] At least the outer surface of the first skirt wall 201 or the second skirt wall 202, which is a skirt wall made of rubber, plastic, or metal (the first skirt wall 201 and the second skirt wall 202 in Fig. 16), has a peripheral wall 203 and through holes 204 and 205. The peripheral wall 203 is the side wall of the cylindrical body constituting the skirt walls 201 and 202. The through hole 204 provided in the first skirt wall 201 connected to the first end wall provided with the spear valve 213 serves as a through hole for gripping. The through hole 205 provided in the second skirt wall 202 connected to the second end wall 212 serves as a through hole for draining water.

[0071] FIG. 18 is a schematic diagram for explaining the support and lifting of the cask shown in FIG. 16 by the support claws. The cask printing system shown in FIG. 18 has the same operational effects as the cask printing system according to the first embodiment shown in FIGS. 4 to 6. In the cask printing system according to the third embodiment, the lifting and rotating device further includes a base body 12, a rotating mechanism of the base body 12, and a lifting mechanism 13 (shown in FIG. 1) of the base body 12. The support component 14 has a slide component 31 attached to the base body 12 and moving in the horizontal direction, and a support claw 30 interlocked with the slide component 31. The support claw 30 is inclined downward toward the outer side in the radial direction of the cask 200, and preferably moves toward the outer side in the radial direction of the cask 200 while contacting the periphery of the through hole 204. Since the support claw 30 supports and lifts the cask 300 by a simple operation of parallel movement, the tact time can be further shortened.

[0072] The lifting and rotating device shown in Fig. 18 is the same as the lifting and rotating device 1 shown in Figs. 1, 2, 4 to 6. When the drive mechanism slides the slide part 31 along the rail 15 from the position of the slide part shown by the dashed line in Fig. 18 to the position of the slide part 31 shown by the solid line, the support claw 30 moves together with the slide part 31. Then, as shown in Fig. 18, the periphery of the through hole 204 slides along the contact part 30a of the support claw 30 as the support claw 30 moves, so that the barrel 200 is supported by the support claw 30 and lifted from the position of the barrel shown by the dashed line in Fig. 18 to the position of the barrel 200 shown by the solid line. Such a movement in which the support part 14 grips the barrel 200 and at the same time raises the barrel 200 contributes to shortening the tact time. The barrel 200 lifted by the support part 14 has its upward movement restricted when the upper end of the upper skirt wall (the first skirt wall in Fig. 18) 201 contacts the pressing part 16 (shown in Fig. 1). Then, the first skirt wall 101 is clamped between the support claw 30 of the support part 14 and the pressing part 16, and the base 12 and the barrel 200 are integrated. By the operation of the rotation mechanism of the base 12, the barrel 200 rotates. The movement in which the support part 14 supports and grips the periphery of the through hole 204 in contact therewith and at the same time raises the barrel 200 not only contributes to shortening the tact time, but also can make the central axis of the barrel 200 and the rotation axis by the rotation mechanism of the base 12 more coincident, thus contributing to improving the printing accuracy. Fig. 18 shows, as an example, a form in which the barrel 200 is supplied to the barrel printing system with the spear valve 213 facing upward, and the support claw 30 supports the through hole 204 provided in the first skirt wall 201. However, the present invention is not limited to this. The barrel 200 may be supplied to the barrel printing system with the spear valve 213 facing downward, and the support claw 30 may support the through hole 205 provided in the second skirt wall 202. The barrel printing system 1 shown in Fig. 1 can shorten the printing tact time regardless of the types of the barrels 100, 200.

[0073] FIG. 19 is a schematic diagram for explaining the support and lifting of the barrel shown in FIG. 16 by a rotating part. The barrel printing system shown in FIG. 19 has the same operational effects as the barrel printing system according to the first embodiment shown in FIG. 9. In the barrel printing system according to the third embodiment, the lifting and rotating device further includes a base body 12, a rotating mechanism of the base body 12, and a lifting mechanism 13 (shown in FIG. 1) of the base body 12. The supporting part 14 is a rotating part 40 attached to and rotating on the base body 12. The rotating part 40 preferably rotates from the inside of the barrel 200 toward the peripheral wall 203 or the through hole 204 to push up the through hole 204. Due to the simple operation of the rotation of the rotating part 40, the barrel can be supported and lifted simultaneously, so that the tact time can be further shortened.

[0074] The supporting part 14 shown in FIG. 19 is the same as the supporting part 14 shown in FIG. 9. When the rotating part 40 rotates from the inner side in the radial direction to the outer side in the radial direction of the barrel 200, the rotating part 40 enters the through hole 204 and contacts the peripheral wall of the through hole 204, for example. By further continuing the rotation, the rotating part 40 pushes up the through hole 204. As a result, the barrel 200 is supported by the rotating part 40 and rises at the same time. In FIG. 19, as an example, the form in which the barrel 200 is supplied to the barrel printing system with the spear valve 213 facing upward and the rotating part 40 is hooked on the through hole 204 of the first skirt wall 201 is shown. However, the present invention is not limited to this. The barrel 200 may be supplied to the barrel printing system with the spear valve 213 facing downward, and the rotating part 40 may be hooked on the through hole 205 of the second skirt wall 201 (shown in FIG. 17) to support and lift the barrel 200 at the same time.

Here, the pressing part 16 is, for example, the disk-shaped part 70 shown in FIG. 12 as shown in FIG. 20(a). By contacting the second end wall 212, the disk-shaped part 70 presses the cask 200 lifted by the supporting part 14 from above to regulate the lifting amount, and at the same time, the central axis O of the cask 200 and the rotation axis by the rotation mechanism of the base 12 can be made to coincide more.

[0089] (Cask printing method) The barrel printing method according to this embodiment is, for example, as shown in FIG. 1, a barrel printing method for printing on the outer surface of the barrel 100. The barrel printing method includes a step of supporting the conveyed barrel 100 and raising the barrel 100 to a predetermined height, and an ink adhesion step of rotating the raised barrel 100 about the central axis O of the barrel 100 while adhering ink to the outer surface of the barrel 100.

[0090] The barrel printing method according to this embodiment can be realized by using the barrel printing system 1 of the first to third embodiments described so far. Taking the barrel printing system 1 shown in FIG. 1 as a representative example, the barrel 100 conveyed by the conveying device 17 is guided to a predetermined position on the conveying surface of the conveying device 17 by the guiding mechanism and stops at a predetermined position directly below the lifting and rotating device 10 by the stopping mechanism. In the lifting and rotating device 10, the supporting component 14 supports and lifts the barrel 100, and the barrel 100 is clamped between the supporting component 14 and the pressing component 16. In this state, the lifting and rotating device 10 rotates the barrel 100, and during this time, the printing device 20 performs printing on the side surface of the barrel 100. By using the lifting and rotating device 10 of the barrel printing system 1 according to this embodiment, the conveyed barrel 100 can be supported and raised to a predetermined height at the same time, and printing can be performed on the outer surface of the barrel 100 while rotating the raised barrel 100. As a result, the tact time is shortened. In addition, in FIG. 1, as an example, a form in which the barrel 100 is an all-metal barrel is shown, but this embodiment is not limited thereto, and it may be a barrel 200 having a skirt wall 201, 202 whose outer surface is made of rubber, plastic or metal and has through holes 204, 205 as shown in FIG. 16, or a resin barrel currently in circulation.

[0091] The bottle printing method according to this embodiment preferably further includes a bottle lowering step and a bottle discharging step after the ink adhesion step. The bottle lowering step is performed by releasing the support of the support component 14. The bottle discharging step is performed by the discharging mechanism 18. After the printing is completed, the support component 14 releases the support of the bottle 100, and the bottle 100 is returned to the conveying surface of the conveying device 17. Then, the discharging mechanism 18 pushes the bottle 100 to the downstream side of the conveying path of the conveying device 17 from the lifting and rotating device 10, and at the same time, the next bottle 100 moves directly below the lifting and rotating device 10, and printing is continuously performed in the same manner.

Example

[0092] Next, the present invention will be described more specifically with reference to examples, but the present invention is not limited to these examples.

[0093] (Example 1) Using the bottle printing system 1 shown in FIG. 1, printing was performed on the side surface of a 7L stainless steel bottle. The printing device 20 used a drop-on-demand full-color inkjet printer (model: KM800, manufactured by Konica Minolta).

[0094] (Comparative Example 1) Using a conventional manufacturing line for winding stretch labels, a stretch label was wound around the outer surface of the conveyed bottle. The winding of the stretch label was performed through the steps of (1) stopping the bottle at a fixed position during conveyance, (2) winding the stretch label around the bottle, (3) heating to shrink the stretch label, and (4) discharging the bottle from the printing system.

[0095] (Comparative Example 2) In the conventional barrel printing system of Comparative Example 1, instead of winding a stretch label, printing was performed on the side surface of the barrel using an inkjet printer. The printing was carried out through the following steps: (1) stopping the barrel at a fixed position during conveyance, (2) gripping the stopped barrel, (3) lifting the barrel, (4) printing while rotating the lifted barrel, (5) lowering the barrel to the conveyor after printing, and (6) discharging the barrel from the printing system. The printing device and the printing content were the same as those in Example 1.

[0096] (Comparative Example 3) In Comparative Example 2, printing was performed in the same manner as in Comparative Example 2, except that improvements such as adding a discharge mechanism and shortening the process transfer time were made.

[0097] Comparative Example 2 aimed at Comparative Example 1, but the tact time was longer than that of Comparative Example 1. In Comparative Example 3, since a plurality of improvements were made to Comparative Example 2, the tact time was shortened compared to Comparative Example 2, but the tact time was longer than that of Comparative Example 1. In contrast, in Example 1, since the gripping and lifting of the barrel were performed simultaneously, the tact time was further shortened compared to Comparative Example 3 and exceeded the tact time of Comparative Example 1. From the above, it was confirmed that the barrel printing system (Example 1) according to the present embodiment can shorten the tact time while reducing the amount of plastic used, as compared with the conventional production line (Comparative Example 1) that winds a stretch label. Also, it was confirmed that the barrel printing system (Example 1) according to the present embodiment can achieve a 25% shortening of the tact time as compared with an example (Comparative Example 2) in which simply changing the winding of the stretch label to printing directly using ink on the barrel surface in the conventional production line (Comparative Example 1) that winds a stretch label. Furthermore, it was confirmed that a 18% shortening of the tact time can be achieved as compared with an example (Comparative Example 3) in which a plurality of improvements were made to Comparative Example 2.
