Description

  The present invention relates to a can water droplet removing device that removes water droplets adhering to a can during transportation of the can, and more particularly, water droplets adhering to the bottom surface of the lower end of a cylindrical can conveyed in the vertical direction of the axis. It is suitable for removal.

  For example, in a can beer manufacturing process, a can filled with beer is washed and then stored in a case. For example, when storing canned beer in a case containing 24 cans, when storing 6 cans, 4 packs stored in a paper pack, and storing unpacked canned beer in a 24 can case There is. In any case, canned beer is stored in the case in the same storage device called a caser, and a can of 6 cans stored in a paper pack or an unpacked can is slid on the upper surface of the stay. Store in. As is well known, cans of can beer have a cylindrical outer shape, and cans are conveyed with the axis line up and down so that the pull tab side is always upward, for example. At this time, if water droplets adhere to the bottom surface of the lower end of the can, the bottom surface of the bottom of the packed paper pack is swollen with moisture, and the paper component adheres to the upper surface of the stay of the storage device. The paper component of the paper pack contains paper fibers in addition to the color, so if the paper component adheres to the upper surface of the stay of the storage device, irregularities are formed, and the can falls over when slipping canned beer . At present, after the storage of the paper pack in the case, the paper component adhering to the stay is manually removed before the unpacked can is stored in the case.

  In order to avoid such problems, it is necessary to remove water droplets adhering to the washed can, particularly water droplets adhering to the bottom surface of the lower end of the can. As such a can water droplet removing device, for example, a device described in Patent Document 1 below can be applied. This water droplet removing device removes water droplets on the side surface of the lower end of the bottle that is conveyed so that the lid side is facing upward, while the bottle is being transported at intervals with a timing screw, and the lower end of the bottle from a plurality of air nozzles Pressurized air is blown onto the side surface to blow off water droplets.

  Next, an embodiment of the can water droplet removing apparatus of the present invention will be described with reference to the drawings. FIG. 1 shows a can beer manufacturing process to which the can water droplet removing apparatus of this embodiment is applied. In this embodiment, a cylindrical can is used, and the can is conveyed with its axis line up and down so that the pull tab side or the opening side is always upward. The can has a cylindrical shape with a bottom until it is covered, and one end in the axial direction is open, and the opening is covered with a lid with a pull tab. That is, the bottom of the bottomed cylindrical shape is downward until the can is covered, and the same bottom is downward after the lid is closed. As is well known, the bottom of the bottom of the can has a central portion that is recessed inwardly in a curved shape. Further, the top surface of the upper end of the covered can is also recessed inward from the uppermost edge.

  In this canned beer manufacturing process, an empty can that is not covered with the depalletizer 1 is first supplied onto the line, and then the necessary items are printed on the bottom of the can with an empty can inkjet printer (IJP in the figure). The can inkjet printer checker 3 determines whether or not necessary items are properly printed. The can on which the necessary items are properly printed is inspected by the inner surface inspection machine 4 and cleaned by the rinser 5. The washed can is filled with the content of the filler 6, that is, beer, and the lid is covered with the seamer 7 (also referred to as winding). The can with the lid is washed and removed with a washing water drop removing device 8 and heated to a room temperature with a heater 10 through a valve monitor 9. In the heated can, water droplets on the top surface of the upper end portion are removed by the can mouth water droplet removing device 11, and whether or not the lid is properly wound by the tightening inspection machine 12 is inspected. The cans with the lids properly wound are attached with seals by a seal labeler 13, and the contents inspection, that is, beer is inspected by a taste inspection machine 14, and the can bottom water drop removing device 15 Water droplets on the bottom surface of the lower end are removed. The cans from which the water droplets on the bottom surface of the lower end are removed are packed into a paper pack, for example, by 6 cans by the multipack caser 16 and then stored in a case containing 24 cans by the caser 17. After the can stored in the case is inspected by the carton inspection machine 18 to be properly stored in the case and the box foreign object inspection machine 19 inspects that no foreign substance is mixed in the case, the palletizer 20 The case is stacked and unloaded.

  In the can beer manufacturing process of this embodiment, the can bottom water drop removing device 15 of the present invention is applied to the can bottom water drop removing device 15 of FIG. Prior to the description of the can bottom water droplet removing device 15, the caser 17 of FIG. 1 will be described. FIG. 2 is a plan view showing a state in which the unpacked can C is stored in the case B by the caser 17 after the lid is tightened, and FIG. 3 is a can pack packed in a paper pack M (also referred to as a multipack). 4 is a plan view of a state where P is stored in a case B. FIG. For example, as shown in FIG. 4, the can pack P packed in the paper pack M packs six cans C per one paper pack M. The case B is a rectangular parallelepiped container made of, for example, corrugated cardboard, and is arranged with one open side facing sideways. A stay 21 that guides the bottom surface of the can C or the pack P is opposed to the opening surface of the case B, and the can C or the pack P pushed by the pusher 22 is stored in the case B while sliding on the upper surface of the stay 21. The

  FIG. 5 shows a part of the developed paper pack M. This paper pack M has been standardized, and the alternate long and short dash line in the figure is folded in a mountain, and the lower part of the figure from the mountain folded part forms the bottom surface of the pack P. Holes H are formed in the corners of the bottom surface of the paper pack M. For example, as shown in FIG. 7, a can for enclosing a beverage has a tapered lower end portion of the outer peripheral surface in order to achieve both weight reduction and strength securing, and a bottom surface continuous with the tapered surface is a central portion. Is recessed in a spherical shape. The hole portion H of the paper pack M is located at the connection portion between the tapered surface at the lower end of the outer peripheral surface of the can C and the bottom spherical recess. Since the connection part of the taper surface of the lower end part of the outer peripheral surface of can C and the bottom spherical spherical recess is the lowermost end part of can C, if water drops adhere to the outer peripheral surface or bottom surface of can C, the water drops , It flows down to the connection between the tapered surface and the depression. When the water droplets adhere to the peripheral edge of the hole H of the paper pack M, the peripheral edge of the hole H becomes soft and the paper component adheres to the upper surface of the stay 21 of the caser 17. As described above, since the paper component contains fibers in addition to the color of the paper pack, when the paper component is solidified, irregularities are formed on the upper surface of the stay 21. When the unpacked can C is slid on the upper surface of the stay 21 having the unevenness, the can C falls down due to the uneven resistance and instability. In order to avoid this problem, it is important to remove water droplets adhering to the outer peripheral surface and the bottom surface of the can C.

  Therefore, in the can beer manufacturing process of this embodiment, the can bottom water droplet removing device 15 is arranged on the upstream side in the can transport direction of the multi-pack caser 16 that packs cans with paper packs. 6 is a plan view showing the state of conveyance of the can C in the vicinity of the can bottom water droplet removing device 15, and FIG. 7 is a front view of the state of conveyance of the can C in FIG. In this embodiment, in order to efficiently remove the water droplets adhering to the outer peripheral surface and the bottom surface of the can C by the can bottom water droplet removing device 15, a double row ( The can C that has been transported in two rows is transported in a single row (one row). Further, the upper and lower portions of the outer peripheral surface of the can C to be conveyed are guided by the guide 23. Therefore, the can C after being made into a single row rotates in one circumferential direction of the outer peripheral surface by contacting the guide 23.

  FIG. 8 is a front view of the can bottom water droplet removing device 15, and FIG. 9 is a bottom view of FIG. In the can bottom water droplet removing device 15, the bottom surface of the lower end of the can C is supported and conveyed by the belt-like body 25 of the conveyor 24. The belt-like body 25 is rotationally driven by a drive source (not shown) and conveys the can C from the right to the left in FIG. This can bottom water drop removing device 15 has a bottom end bottom water drop removing unit 26 that blows off water drops adhering to the bottom end of the can C from the upstream side of the can conveyance, and a water drop adhering to the outer peripheral surface of the bottom end of the can C. The outer peripheral surface water droplet removing unit 27 for blowing off the outer peripheral surface and the outer peripheral surface water droplet removing unit 28 for blowing off the water droplets adhering to the outer peripheral surface of the can C are sequentially formed. The bottom surface bottom surface water drop removing unit 26 blows pressurized water on the bottom surface of the bottom end of the can C through the belt-like body 25 of the conveyor 24 to blow off water droplets adhering to the bottom surface of the bottom end of the can C. The lower end outer peripheral surface water droplet removing unit 27 blows the water droplets attached to the lower end outer peripheral surface of the can C by blowing pressurized air onto the lower end outer peripheral surface of the can C. The outer peripheral surface water droplet removing unit 28 blows the water droplets attached to the outer peripheral surface of the can C by blowing pressurized air onto the outer peripheral surface of the can C over the axial direction.

  In the bottom surface bottom surface water droplet removing unit 26, pressurized air is blown over the belt 25 of the conveyor 24 to blow off water droplets adhering to the bottom surface of the bottom of the can C. It has air permeability through which air passes. Fig. 10a is a plan view of the band 25 of the conveyor 24 used in this embodiment, and Fig. 10b is a front view thereof. The belt-like body 25 is formed in a belt-like shape by connecting resin pieces 29 with pins 30 so as to be rotatable relative to each other, and has flexibility when the pieces 29 rotate. Of the strip 25, the shaded portion is the frame 29, and the white portion is the hole 31 (manufactured by Tsujimoto Chain: 53% aperture ratio). Therefore, pressurized air passes through the hole 31 and is blown to the bottom surface of the lower end of the can C.

  FIG. 11 is a right side view of the bottom surface bottom surface water droplet removing unit 26 of FIG. 8. The bottom end bottom surface water droplet removal unit 26 includes a single bottom surface air nozzle 33 in which a blowout port 32 for pressurized air is provided. The bottom air nozzle 33 is connected to a pressurized air supply pipe (not shown). The bottom air nozzle 33 is arranged so that the pressurized air blown from the outlet 32 of the bottom air nozzle 33 is blown obliquely upward toward the upstream side in the can conveying direction. As described above, the center of the bottom surface of the can C is recessed in a curved shape, and in order to blow off water droplets adhering to the recess with pressurized air, the blowing speed of the pressurized air is important. Therefore, by directing the pressurized air blown from the blow-off port 32 of the bottom air nozzle 33 toward the upstream side in the can conveying direction, the can conveying speed is taken into consideration in addition to the blowing speed of the pressurized air, and the blowing speed of the pressurized air Becomes larger. Further, by directing the pressurized air blowing direction toward the upstream side of the can conveying direction, the water droplets blown off from the bottom surface of the bottom end of the can C are reattached to the can C which has already passed through the bottom surface bottom surface water droplet removing unit 26. Can also be avoided.

  12 is a right side view of the outer peripheral surface water droplet removing unit 27 in FIG. 8, and FIG. 13 is a right side view of the outer peripheral surface water droplet removing unit 28 in FIG. Among these, the lower end outer peripheral surface water droplet removing unit 27 includes a pressurized air blowing mechanism called the lower end portion air knife 34, and the outer peripheral surface water droplet removing unit 28 includes an outer peripheral surface air knife 35. The lower end air knife 34 and the outer peripheral surface air knife 35 in this embodiment have the same configuration. Fig. 14a shows a front view of the lower end air knife 34 and the outer peripheral surface air knife 35, and Fig. 14b shows a right side view thereof. The air knives 34 and 35 are formed by, for example, bending a metal plate material into a heptagonal shape with a cross-sectional shape to form a pipe 36, projecting both ends of the plate material in the bending direction into a flange shape, and joining the joint portion with a slight gap. To provide a pressurized air outlet 37. One end of the pipe 36 in the axial direction is closed with a lid member 38, and an individual cylindrical pipe 39 is airtightly connected to the other end. If a pressurized air supply pipe (not shown) is connected to the cylindrical pipe 39, the pressurized air is continuously blown out from the blowout port 37. That is, in the air knives 34 and 35, the pressurized air outlet 37 is continuous in a preset direction.

  The lower end air knife 34 of the lower end outer peripheral surface water droplet removing unit 27 is arranged in parallel with the can conveying direction with the blowing port 37 facing the outer peripheral surface of the lower end of the can C on both sides in the can conveying direction. . That is, the lower end air knife 34 is arranged so that the pressurized air blown from the blowout port 37 is continuously blown to the outer peripheral surface of the lower end portion of the can C as the can C is conveyed. Further, the lower end air knife 34 is disposed so that the pressurized air is blown obliquely downward from the outlet 37 of the lower end air knife 34. As described above, the lower end portion of the outer peripheral surface of the can C that encloses the beverage is tapered. The water droplets adhering to the outer peripheral surface lower end taper surface, and in some cases the water droplets blown off by the lower end bottom surface water droplet removing unit 26 and reattached to the outer peripheral surface lower end taper surface, the outlet 37 of the lower end air knife 34. The compressed air blown out from the outer peripheral surface of the can C is continuously blown to the lower end of the outer peripheral surface of the can C as the can C is conveyed, By spraying on the lower end portion, the water droplets are blown away from the lowermost end portion of the can C, whereby the water droplets adhering to the lower end portion of the outer peripheral surface of the can C can be effectively removed.

  On the other hand, the outer peripheral surface air knife 35 of the outer peripheral surface water droplet removing unit 28 has the blowing port 37 facing the outer peripheral surface of the can C on both sides in the can transport direction, and the upstream side in the can transport direction is downward and the downstream side in the can transport direction is upward. The main body is arranged diagonally. That is, as the can C is transported, the pressurized air blown from the blowout port 37 moves upward from below the outer peripheral surface of the can C, and as a result, is added to the outer peripheral surface of the can C along the axial direction of the can C. Pressurized air is blown. Further, the outer peripheral surface air knife 35 is arranged so that the pressurized air is blown obliquely upward from the outlet 37 of the outer peripheral surface air knife 35. Accordingly, water droplets adhering to the outer peripheral surface of the can C, and in some cases, water droplets reattached from the lower end bottom surface and the lower end outer peripheral surface of the can C at the lower end bottom surface water droplet removing unit 26 and the lower end outer surface water droplet removing unit 27. Is blown upward from the outer peripheral surface of the can C, or blown away so as to move upward from the lower peripheral surface of the can C, thereby effectively removing water droplets adhering to the outer peripheral surface of the can C. Can be removed.

  FIG. 15 is a cross-sectional view of the can C before the contents, that is, beer is enclosed and transported to the can bottom water droplet removing device 15, and in this state, the water droplets D adhere to the bottom surface and the outer peripheral surface of the can C. ing. FIG. 16 is a cross-sectional view of the can C in the bottom surface bottom surface water droplet removing unit 26, and the water droplet D on the bottom surface of the bottom end that is recessed in a curved shape of the can C by the pressurized air sprayed on the bottom surface of the bottom end of the can C The water droplets D on the bottom surface of the lower end of the can C are efficiently removed by being blown away. FIG. 17 is a cross-sectional view of the can C in the lower end outer peripheral surface water droplet removing unit 27, and the lower end of the can C tapered by the pressurized air blown downward onto the lower end outer peripheral surface of the can C. The water droplets D on the outer peripheral surface are blown away from the tapered surface and the bottom surface, and the water droplets D on the outer peripheral surface of the lower end of the can C are efficiently removed. FIG. 18 is a cross-sectional view of the can C in the outer peripheral surface water droplet removing unit 28, and the water droplets D on the outer peripheral surface of the can C are blown upward by the pressurized air sprayed upward from the lower side to the upper side of the can C side. Or the water droplets D on the outer circumferential surface of the can C are efficiently removed.

  When the water droplet weight per can of 350 mL can be compared before and after being transported to the can bottom water droplet removing device 15 in this embodiment, it is 56 mg / can after the device, compared with 176 mg / can before the device. The adhesion amount of was able to be reduced to 1/3 or less. As a result, the paper fibers of the paper pack M do not adhere to the stay 21 of the caser 17, and there is no paper fiber removal work performed before the introduction of the can bottom water droplet removing device 15. In addition, it is thought that this effect is related to the fact that the can C rotates in one circumferential direction along the outer peripheral surface in the can bottom water droplet removing device 15.

The belt-like body 25 has air permeability through which pressurized air passes. Therefore, in the lower end bottom surface water droplet removing unit 26, the pressurized air is blown over the belt-like body 25 of the conveyor 24 to blow off the water droplets adhering to the bottom end bottom surface of the can C. Further, the lower end outer peripheral surface water droplet removing unit 27 blows pressurized air on the lower end outer peripheral surface of the can C to blow away water droplets adhering to the lower end outer peripheral surface of the can C. Further, the outer peripheral surface water droplet removing unit 28 blows the water droplets adhering to the outer peripheral surface of the can C by blowing pressurized air onto the outer peripheral surface of the can C over the axial direction. As a result, water droplets adhering to the can C can be removed including the bottom surface of the lower end of the can C whose axis is directed in the vertical direction.

Further, by arranging the lower end bottom surface water droplet removing unit 26, the lower end outer peripheral surface water droplet removing unit 27, and the outer peripheral surface water droplet removing unit 28 in this order from the upstream side in the conveyance direction of the can C, the can C whose axis is directed in the vertical direction. Water droplets can be effectively removed from the bottom surface of the lower end portion.
Further, the bottom surface air nozzle 33 provided in the bottom surface bottom surface water droplet removing unit 26 has a single compressed air blowing port 32, and the pressurized air blown from the blowing port 32 is upstream in the conveyance direction of the can C. The bottom air nozzle 33 is arranged so as to be blown obliquely upward. Thereby, the transport speed of the can C can be added to the speed of the pressurized air blown from the outlet 32 of the bottom air nozzle 33 to effectively blow off water droplets, and the bottom water bottom surface water drop removing unit 26 has been passed. It is possible to avoid the water droplets blown off by the bottom surface bottom surface water droplet removing unit 26 from adhering to the can, and the water droplets adhered to the bottom surface of the bottom end of the can C can be more effectively removed.

The lower end air knife 34 provided in the lower end outer peripheral surface water droplet removing unit 27 has a pressurized air blowing port 37 continuous in a preset direction, and the pressurized air blown from the blowing port 37 can be The lower end air knife 34 is arranged so as to be continuously blown to the outer peripheral surface of the lower end portion of the can C as C is conveyed. Thereby, the water droplet adhering to the lower end part outer peripheral surface of the can C is blown away so that it may space apart from the lower end part bottom face of the can C, and the adhesion of the new water droplet to the can lower end part bottom face is avoided, and it is more effective. In particular, water droplets adhering to the bottom surface of the lower end of the can C can be removed.
Further, by arranging the lower end air knife 34 so that the pressurized air is blown obliquely downward from the outlet 37 of the lower end air knife 34, the water droplets adhering to the outer peripheral surface of the lower end portion of the can C are more Water droplets that are effectively blown away from the bottom surface of the lower end of the can C and that are more effectively removed from the bottom surface of the lower end of the can C can be removed.

Further, the outer peripheral surface air knife 35 provided in the outer peripheral surface water droplet removing unit 28 has a pressurized air blowing port 37 continuous in a preset direction, and the pressurized air blown out from the blowing port 37 is in the can C. The outer peripheral surface air knife 35 is arranged so as to move upward from below the outer peripheral surface with the conveyance. Thereby, the water droplets adhering to the outer peripheral surface of the can C are blown upward from the outer peripheral surface of the can, or blown away so as to move upward from below the outer peripheral surface of the can to the bottom surface of the lower end of the can. Thus, it is possible to more effectively remove the water droplets adhering to the bottom surface of the lower end portion of the can C.
