[0008] The can lid row conveying system is a system for supplying and conveying a row of can lids, each of which is made up of a plurality of substantially disk-shaped can lids that are in close contact with one another and extend in a cylindrical shape. The configuration of one example (embodiment) of a can lid row conveying system will be described with reference to FIGS. FIG. 1 is a diagram (top view) showing the overall configuration of a can lid row conveying system 1. 2 to 4 are diagrams showing the configuration in the AA direction in FIG. FIG. 5 is a configuration diagram of the BB direction in FIG. Although the can lid row T is not shown in FIG. 1, the can lid row T is shown in FIGS.

[0009] The can lid row conveying system 1 includes a supply device 10, a conveying device 20, and a control device (not shown). The supply device 10 is a device that supplies a row of can lids T to the conveying device 20. The conveying device 20 is a device that conveys the row of can lids T supplied from the supplying device 10. The control device is a device that controls the supply device 10 and the transport device 20.

[0010] The direction in which the can lid row T extends cylindrically is the longitudinal direction (x-axis direction in the drawing), and the direction perpendicular to the longitudinal direction is the lateral direction (z-axis direction in the drawing).

[0011] The supply device 10 includes a mounting member 11 , a supply table 12 , a pushing member 13 , a first guide member 14 , and a partition member 15 . The placing member 11 is a member that places the row of can lids T on the supply table 12 at a predetermined position. The supply table 12 is a table on which the row of can lids T is placed.

[0012] The mounting member 11 includes a preparation table 11A, a moving part 11B, and a transfer table 11C. The preparation table 11A is a table that supports the row of can lids T to be placed on the supply table 12, and is located at a higher position than the supply table 12. The operating unit 11B is a member that pushes the can lid row T on the preparation table 11A in the short side direction, thereby pushing the can lid row T onto the transfer table 11C. The transfer table 11C is an inclined table that connects the preparation table 11A and the supply table 12. The row of can lids T is pushed out from the preparation table 11A by the operating part 11B, and moves down the transfer table 11C by its own weight, and is placed at a predetermined position on the supply table 12.

[0013] The preparation table 11A may include bag removal units 11A1, 11A2 for removing the cut bags covering the can lid row T. Although not shown, the can lid row conveying system 1 may also include a bag opening device that performs a process of cutting open the bags covering the can lid row T as a process preceding the process of removing the bags. The bag removal unit includes a pair of peeling rollers 11A1, 11A2 that rotate the can lid row T to peel off the bags covering the can lid row T. With the target object T placed on the pair of peeling rollers, the rollers 11A1, 11A2 are operated to peel off and remove the bags from the can lid row T. After the bags are removed from the row of can lids T, the operating section 11B operates and places the row of can lids T on the supply table 12.

[0014] The supply table 12 is an elongated table extending in the same direction as the longitudinal direction of the row of can lids T to be placed thereon, and is connected to the conveying device 20. The row of can lids T is placed by the placing member 11 at a first position P1, which is a predetermined position on the supply table 12, and then transported on the supply table 12 along the longitudinal direction of the row of can lids T. Hereinafter, the direction in which the row of can lids T is transported may be referred to as the transport direction. The front end of the can lid row T in the conveying direction is referred to as a front end TF, and the rear end thereof is referred to as a rear end TB. The length in the longitudinal direction of the row of can lids placed from the placing member 11 onto the supply table 12 is constant (the number of can lids constituting the row of can lids is constant).

[0015] The pushing member 13 is a member that pushes out and guides the rear end portion TB of the row of can lids T placed on the supply table 12. The pushing member 13 is located on the most upstream side of the first guide member 14 and the partition member 15 in the conveying direction. The pushing member 13 is a cylindrical rod-like member that can advance and retreat in the longitudinal direction of the row of can lids T.

[0016] The first guide member 14 is a member that guides the can lid row T by leading the front end portion TF or by pushing out the rear end portion TB. The first guide member 14 has a guide portion 14A that engages with the row of can lids T. The first guide member 14 has a rail portion 14B extending in the longitudinal direction, and a first movable portion 14C that moves along the rail portion 14B. The first guide member 14 has a second movable portion 14D that is movable back and forth in the vertical direction (the y-axis direction in the drawing).

[0017] The guide portion 14A of the first guide member 14 that engages with the can lid row T is a plate-shaped member including a flat portion, as shown in Figures 2 to 5, and includes a cutout portion 14AC that corresponds to the shape of the push-out member 13 and the second guide member 22. The inclusion of the cutout portion 14AC allows the first guide member 14 and the push-out member 13 to simultaneously engage with the rear end TB of the can lid row T, and the first guide member 14 and the second guide member 22 to simultaneously engage with the front end TF or rear end TB of the can lid row T. In other words, this configuration allows the guide of the can lid row T to be smoothly transferred from the push-out member 13 to the first guide member 14, or from the first guide member 14 to the second guide member 22.

[0018] When the guide portion 14A of the first guide member 14 (hereinafter sometimes simply referred to as the first guide member 14) advances downward, the first guide member 14 can be engaged with the front end portion TF or the rear end portion TB of the can lid row T. With the first guide member 14 and the front end TF or rear end TB of the can lid row T engaged, the first guide member 14 can guide the can lid row T by moving in the longitudinal direction. In FIG. 3, the first guide member 14 is advanced downward, and the first guide member 14 and the front end portion TF of the can lid row T are engaged with each other.

[0019] When the first guide member 14 is retracted upward, the first guide member 14 does not engage with the front end TF or the rear end TB of the can lid row T. When the first guide member 14 is not engaged with the front end TF or rear end TB of the can lid row T, the first guide member 14 can move in the longitudinal direction without guiding the can lid row T.

[0020] The partition member 15 is a member that separates the row of can lids T that has been previously guided on the supply table 12 from the row of can lids T that will be newly placed on the supply table 12. The partition member 15 is a member that guides the rear end portion TB of the can lid row T by pushing it out. The partition member 15 has a guide portion 15A that engages with the row of can lids T. The partition member 15 has a rail portion 15B extending in the longitudinal direction, and a first moving portion 15C that moves along the rail portion 15B.

[0021] As shown in FIG. 2, the guide portion 15A is in the form of a plate including a flat portion, and includes a notch 15AC corresponding to the shape of the push-out member 13. By including the cutout portion 15AC, the push-out member 13 and the partition member 15 can simultaneously engage with the rear end portion TB of the can lid row T. In other words, this configuration allows the guide of the can lid row T to be smoothly transferred from the push-out member 13 to the partition member 15.

[0022] The partition member 15 has a second moving part 15D that rotates the guide part 15A so that the guide part 15A is positioned above the supply table 12. When the guide portion 15A of the partition member 15 (hereinafter sometimes simply referred to as the partition member 15) is positioned on the supply table 12, the partition member 15 and the rear end portion TB of the can lid row T can be engaged with each other. With the partition member 15 and the rear end portion TB of the can lid row T engaged, the partition member 15 moves in the longitudinal direction of the can lid row T, thereby guiding the can lid row T. FIG. 4 shows a state in which the partition member 15 is positioned on the supply table 12 and the partition member 15 and the rear end portion TB of the can lid row T are engaged with each other.

[0023] When the partition member 15 is not positioned on the supply table 12, the partition member 15 and the rear end portion TB of the can lid row T are not engaged with each other. When the partition member 15 and the rear end portion TB of the can lid row T are not engaged with each other, the partition member 15 can move in the longitudinal direction without guiding the can lid row T.

[0024] The row of can lids T is conveyed within the supply device 10 (on the supply table 12) by being guided along the longitudinal direction by at least one of the pushing member 13, the first guide member 14, and the partition member 15.

[0025] The transport device 20 includes a conveyor 21 and a second guide member 22 . The conveyor 21 is connected to the supply table 12 and transports the row of can lids T supplied from the supply device 10. The conveyor 21 is a so-called belt conveyor that rotates an endless strip 21A to transport the row of can lids T downstream along the longitudinal direction.

[0026] The second guide member 22 is a member that guides the can lid row T by leading the front end portion TF or by following the rear end portion TB. The second guide member 22 has a guide portion 22A that engages with the row of can lids T. The second guide member 22 has a rail portion 22B that extends in the same direction as the conveyor 21, and a moving portion 22C that moves along the rail portion 22B. The guide portion 22A is a long rod-shaped member and includes an expandable and contractible mechanism 22D. As shown in FIGS. 1 and 5, the guide portion 22A of the second guide member 22 that engages with the can lid row T is cylindrical.

[0027] When the extension mechanism 22D of the second guide member 22 is extended, the guide portion 22A of the second guide member 22 (hereinafter sometimes simply referred to as the second guide member 22) can be engaged with the front end portion TF or rear end portion TB of the can lid row T. With the second guide member 22 and the front end TF or rear end TB of the can lid row T engaged, the second guide member 22 moves along the conveyor 21, thereby guiding the can lid row T. FIG. 5 shows the second guide member 22 in an extended state, and the second guide member 22 and the front end portion TF of the can lid row T are engaged with each other.

[0028] When the second guide member 22 is contracted, the second guide member 22 does not engage with the front end TF or the rear end TB of the can lid row T. When the second guide member 22 is not engaged with the front end TF or rear end TB of the can lid row T, the second guide member 22 can move along the conveyor 21 without guiding the can lid row T.

[0029] The row of can lids T is conveyed in the conveying device 20 (on the conveyor 21) by being guided in the longitudinal direction by the conveyor 21, or by the conveyor 21 and the second guide member 22.

[0030] The control device has a processor that executes an operating system, applications, programs, etc., a main memory unit such as RAM (Random Access Memory), an auxiliary memory unit such as an IC card, hard disk drive, SSD (Solid State Drive), flash memory, etc., an input unit that accepts information, an output unit that transmits (outputs) control information to the supply device 10 or the conveying device 20, and a communication control unit such as a network card, wireless communication module, mobile communication module, etc.

[0031] The control device may be, for example, a stationary or portable computer, or a server located in the cloud or on a network. It may also be a mobile terminal such as a smartphone, tablet, mobile phone, or personal digital assistant (PDA). Or it may be a combination of multiple of these terminals. For example, a combination of one smartphone and one wearable terminal can logically function as one terminal. It may also be other information processing terminals. In this embodiment, the control device is a stationary computer, which is located near the supply device 10 and the transport device 20, although not shown.

[0032] A processor in the control device (hereinafter simply referred to as the control device) executes the control flow described below. FIG. 6 shows an example of a flow 100 for starting supply of a can lid row. The can lid row supply start flow 100 is a flow in which the control device controls each component of the supply device 10 to start supplying the can lid row T to the conveying device 20.

[0033] First, the control device controls the placing member 11 to place the can lid row T placed first, so that the rear end TB of the foremost can lid row is located at the first position P1 on the supply table 12 (step 101).

[0034] FIG. 7 illustrates a state in which the leading can lid row T is placed on the preparation table 11A of the placement member 11. FIG. 8 illustrates a state in which the leading edge of the can lid row T has been pushed out from the state in FIG. 7 by the operating part 11B and placed on the supply table 12 (a state in which the control of step 101 has been performed). The "first position P1" is a position near the tip of the pusher member 13 when the pusher member 13 is in the most retracted state in the longitudinal direction.

[0035] Next, the control device guides the front end TF of the foremost can lid row T with the first guide member 14 and pushes out the rear end TB of the foremost can lid row T with the push-out member 13, thereby guiding the rear end TB of the foremost can lid row T to the second position (step 102).

[0036] FIG. 9 is a configuration diagram of the can lid row conveying system 1 in a state where the control of step 102 has been performed. The "second position P2" is a position near the tip of the pusher member 13 when the pusher member 13 is in the most advanced state in the longitudinal direction. In other words, the pusher member 13 can push the rear end TB of the can lid row T from the first position P1 to the second position P2.

[0037] Next, the control device transfers the guide for the rear end TB of the foremost can lid row T from the push-out member 13 to the partition member 15, leads the front end TF of the foremost can lid row T with the first guide member 14, and pushes out the rear end TB with the partition member 15, thereby guiding the rear end TB of the foremost can lid row T to the third position P3 (step 103).

[0038] FIG. 10 illustrates a state in which the guide for the rear end TB of the foremost can lid row T has been transferred from the pushing member 13 to the partition member 15. Figure 11 shows a state in which, from the state shown in Figure 10, the front end TF of the foremost can lid row T is guided by the first guide member 14 and the rear end TB is pushed out by the partition member 15, thereby guiding the rear end TB of the foremost can lid row T to the third position P3 (a state in which the control of step 103 has been performed). The "third position P3" is a position near the front end TF of the foremost can lid row T when the rear end TB of the foremost can lid row T is located at the first position P1.

[0039] Next, the control device places a subsequent can lid row T, which is a new can lid row T following the forefront can lid row T, on the first position P1 of the supply table 12 by the placement member 11 (step 104). FIG. 12 is a configuration diagram of the can lid row conveying system 1 in a state where the control of step 104 has been performed.

[0040] Next, the control device pushes out the rear end TB of the trailing can lid row T using the push-out member 13, while simultaneously releasing the partition member 15 that guides the rear end TB of the leading can lid row T from its locked state, and in conjunction with the push-out member 13, leads the front end TF of the leading can lid row T using the first guide member 14, guiding the front end TF of the can lid row T (leading can lid row T) to the fourth position P4 (step 105).

[0041] FIG. 13 shows a state in which the rear end TB of the trailing can lid row T is pushed out by the push-out member 13, and at the same time, the partition member 15 guiding the rear end TB of the leading can lid row T is released from the locked state. Figure 14 shows the state in which the first guide member 14, in conjunction with the push-out member 13, leads the front end portion TF of the foremost can lid row T, and guides the front end portion TF of the can lid row T (foremost can lid row T) to the fourth position P4 (the state in which the control of step 105 has been performed). The "fourth position P4" is a position near the connection between the supply table 12 of the supply device 10 and the conveyor 21 of the transport device 20.

[0042] At step 105, this flow 100 ends, and then the conveying device 20 executes control of the can lid row conveyance start flow 200, and the supplying device 10 executes control of the can lid row supply end flow 300.

[0043] FIG. 15 shows an example of a flow 200 for starting the conveyance of a row of can lids. The can lid row conveyance start flow 200 is a flow executed after the can lid row supply start flow 100. The can lid row conveyance start flow 200 is a flow in which the control device controls each member of the conveyance device 20 to start and continue conveying the can lid row T.

[0044] First, the control device transfers the guiding of the front end TF of the can lid row T from the first guide member 14 to the second guide member 22 (step 201). In other words, the control device transfers the guiding of the front end TF of the can lid row T from the first guide member 14 to the second guide member 22. Next, the control device operates the conveyor 21 and guides the front end TF of the row of can lids T by using the second guide member 22 to transport the row of can lids T (step 202). FIG. 16 is a configuration diagram of the can lid row conveying system 1 in a state where the control of step 202 has been performed. In Figure 16, a portion of the first guide member 14 is shown with a dotted line, which means that the guide portion 14A of the first guide member 14 is not engaged with the can lid row T (is retracted upward) (the same applies to other figures).

[0045] The control device controls the second guide member 22 to apply a force in the opposite direction to the conveying direction to the front end TF of the conveyed can lid row T. Specifically, the control device controls the movement speed of the second guide member 22 to be slower than the running speed of the conveyor 21. As a result of this control, the second guide member 22 applies a force in the opposite direction to the conveying direction to the front end TF of the can lid row T being conveyed.However, when a force of a certain amount or more in the conveying direction is applied to the second guide member 22 from the can lid row T, the movable part 22C of the second guide member 22 is configured to be slippery, so the second guide member 22 does not interfere with the conveying of the can lid row T.

[0046] Next, when the front end TF of the conveyed row of can lids T reaches the final conveyance position, which is a predetermined position, the control device stops the second guide member 22 and the conveyor 21 (step 203).

[0047] Finally, when the engagement between the second guide member 22 and the can lid row T is released (when the second guide member 22 is in a contracted state), the control device controls the second guide member 22 to be moved to the vicinity of the supply device 10 (fourth position P4) and controls the conveyor 21 to resume operation (step 204).By this control, the can lid row T continues to be transported.

[0048] In this embodiment, since a worker (person) is positioned at the final conveying position in the can lid row conveying system 1, the engagement between the second guide member 22 and the can lid row T is released by hand, but in other embodiments, the engagement between the second guide member 22 and the can lid row T may be released by mechanical control.

[0049] At step 204, this flow 200 ends, and then the conveying device 20 executes control of the can lid row conveyance end flow 400.

[0050] FIG. 17 shows an example of a can lid row supply completion flow 300. The can lid row supply end flow 300 is a flow executed after the can lid row supply start flow 100. The can lid row supply completion flow 300 is a flow in which the control device controls each component of the supply device 10 to continue and end the supply of the can lid row T to the conveying device 20.

[0051] First, the control device guides the rear end TB of the can lid row T to the second position P2 by the push-out member 13 (step 301). FIG. 18 is a configuration diagram of the can lid row conveying system 1 in a state where the control of step 301 has been performed.

[0052] Next, the control device determines whether a subsequent can lid row T, which is a new can lid row T, can be additionally supplied (step 302). Specifically, in this embodiment, whether or not a can lid row T exists on the preparation table 11A of the mounting member 11 is detected by a sensor (not shown) provided near the preparation table 11A.

[0053] If the control device determines that a new subsequent can lid row T can be additionally supplied (Yes in step 302), the guide for the rear end TB of the can lid row T is transferred from the pushing member 13 to the partition member 15, and the rear end TB of the can lid row T is guided to the third position P3 by the partition member (step 303). FIG. 19 is a configuration diagram of the can lid row conveying system 1 in a state where the control of step 303 has been performed.

[0054] Next, the control device places the succeeding row of can lids T on the first position P1 of the supply table 12 by the placing member 11 (step 304). FIG. 20 is a configuration diagram of the can lid row conveying system 1 in a state where the control of step 304 has been performed.

[0055] Next, the control device guides the rear end TB of the trailing can lid row T using the push-out member 13, and at the same time controls the partition member 15 guiding the rear end TB of the preceding can lid row T to be released from its locked state (step 305). FIG. 21 is a configuration diagram of the can lid row conveying system 1 in a state where the control of step 305 has been performed.

[0056] Next, the control device repeatedly executes the above-described control from step 301 onwards. By this control, the row of can lids T is continuously supplied from the supply device 10 to the conveying device 20.

[0057] On the other hand, if the control device determines in the above-mentioned step 302 that a new subsequent can lid row T cannot be additionally supplied (No in step 302), the control device transfers the guide for the rear end portion TB of the can lid row T from the pushing member 13 to the first guide member 14, and uses the first guide member 14 to push and guide the rear end portion TB of the can lid row T to the fourth position P4 (step 306).

[0058] FIG. 22 is a configuration diagram of the can lid row conveying system 1 in a state where the guide for the rear end portion TB of the can lid row T has been transferred from the pushing member 13 to the first guide member 14. FIG. 23 is a configuration diagram of the can lid row conveying system 1 in a state where the rear end TB of the can lid row T is pushed and guided by the first guide member 14 to the fourth position P4 (a state where the control of step 306 has been performed).

[0059] The control device controls each member so that the speed at which the row of can lids T is pushed out by the push-out member 13, the first guide member 14, and the partition member 15 is the same as the running speed of the conveyor 21 of the transport device 20.

[0060] At step 306, this flow 300 ends, and then control of the can lid row transfer end flow 400 is executed.

[0061] FIG. 24 shows an example of a flow 400 for completing the transfer of a row of can lids. The can lid row conveyance end flow 400 is a flow that is executed after the can lid row conveyance start flow 200 and the can lid row supply end flow 300. The can lid row conveyance completion flow 400 is a flow in which the control device controls each member of the conveyance device 20 to complete the conveyance of the can lid row T.

[0062] First, the control device transfers the guiding of the rear end TB of the can lid row T from the first guide member 14 to the second guide member 22 (step 401). In other words, the control device controls the guiding of the rear end TB of the can lid row T to be handed over from the first guide member 14 to the second guide member 22.

[0063] The conveying device 20 has an extension member (not shown) that can push out the rear end of the guide portion 22A of the second guide member 22, thereby putting the guide portion 22A into an extended state (a state in which it can engage with the can lid row T). The control device executes step 401 by operating the extension member and engaging the second guide member 22 with the rear end TB of the can lid row T. FIG. 25 is a configuration diagram of the can lid row conveying system 1 in a state where the control of step 401 has been performed.

[0064] The control device controls the conveyor 21 to operate (not stop) even when the second guide member 22 takes over the guidance of the rear end TB of the can lid row T from the first guide member 14 (step 401).

[0065] Next, the control device causes the second guide member 22 to follow and guide the rear end TB of the can lid row T (step 402). FIG. 26 is a configuration diagram of the can lid row conveying system 1 in a state where the control of step 402 has been performed.

[0066] In step 402, the control device controls the second guide member 22 to apply a force in the same direction as the conveying direction to the rear end TB of the conveyed can lid row T. Specifically, the control device controls the movement speed of the second guide member 22 to be greater than the running speed of the conveyor 21. With this control, the second guide member 22 applies a force in the same direction as the conveying direction to the rear end TB of the can lid row T being conveyed, but when a force of a certain amount or more is applied to the second guide member 22 from the can lid row T in the opposite direction to the conveying direction, the movable part 22C of the second guide member 22 is configured to be slippery, so that the second guide member 22 is prevented from pushing out the entire can lid row T being conveyed.

[0067] Next, when the rear end TB of the conveyed row of can lids T reaches the final conveyance position, the control device stops the second guide member 22 and the conveyor 21 (step 403). Finally, the control device transfers the second guide member 22 to the vicinity of the supply device 10 (fourth position P4) (step 404).

[0068] The flow 400 ends at step 404. That is, the conveyance of the supplied row of can lids T is completed. The system allows the row of can lids to be smoothly supplied and conveyed.

[0069] Although the present invention has been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications and improvements are possible within the scope of the gist of the present invention. [Explanation of symbols]
