Description

  The present invention relates to a container transport system, and more particularly to a container transport system capable of temporarily stopping transport of a container while transporting a container along a container transport path.

  In order to put a cylindrical label or a cap on a bottle having a neck formed upward from the trunk, the bottle is transported by a conveyor device, temporarily stopped, and covered with a cylindrical label or the like. In this case, in order to prevent the bottle position from fluctuating, a device such as a conveyor device is devised. For example, in a system in which a pair of timing screws whose directions of turning are opposite to each other along the conveying direction are arranged and a bottle is sandwiched between spiral grooves facing each other by driving and rotating in opposite directions to each other, A portion having no lead angle of the spiral groove is provided, and this is used as a stopping part to temporarily stop the progress of the bottle conveyance.

  When a cylindrical label or the like is put on the stationary part in this timing screw conveyance system, the bottle is sandwiched between the spiral grooves facing each other, so that the position of the neck that puts the cylindrical label or the like may fluctuate.

  For this purpose, Patent Document 1 includes a holding means for holding the neck of the bottle when the body of the bottle enters the stop, and opening the neck of the bottle when the body of the bottle is removed from the stop. Providing is disclosed.

Japanese Patent No. 2979313

  According to the method disclosed in Patent Document 1, when the size of a bottle that is a container to be transported is changed, it may be necessary to replace the holding means as well as the timing screw.

  An object of the present invention is to provide a container transport system including a stopping device that can firmly hold a container to be transported. Another object is to provide a container transport system including a stopping device that can flexibly cope with a change of a container to be transported. The following means contribute to at least one of the above objects.

  A container transport system according to the present invention includes a container guide mechanism that guides and feeds a container along a container transport path at a predetermined transport pitch, and a transport direction on both sides of the container transport path on the downstream side of the container guide mechanism. Two sets of rotating belts arranged in parallel and facing each other at a predetermined predetermined width interval, one set of rotating belts facing each other at the width interval of the lower body of the container, and the other set of rotating belts Face each other at the width of the lower end of the upper label mounting portion where the label is mounted on the container, and each set of rotating belts circulates between at least two shafts spaced apart along the transport direction. A pair of rotating belts that hold the container between the opposite belt surfaces, and a container that detects whether or not the container has been transported to a predetermined detection position on the downstream side of the container guide mechanism Based on the detection of the container by the ejecting means and the container detecting means, the movement of the two sets of rotating belts is stopped, the containers are held by the two sets of rotating belts and stopped, and the label is attached to the container at the stopped position. And a control device that is mounted and releases the stop of the two sets of rotating belts under a predetermined release condition set in advance to resume movement.

  In the container transport system according to the present invention, it is preferable that at least one pair of rotating belts has a holding claw portion that holds the outer periphery of the container.

  In the container transport system according to the present invention, it is preferable that each set of rotating belts includes a width adjusting unit that varies a predetermined width interval arranged in parallel.

  With the above configuration, the container transport system includes two sets of rotating belts disposed on both sides of the container transport path so as to face each other in parallel along the transport direction on the downstream side of the container guide mechanism. One set of rotating belts faces each other at the width interval of the lower body portion of the container, and the other set of rotating belts faces each other at the width interval of the lower end portion of the upper label mounting portion where the label is mounted on the container. The rotating belt holds the container between the belt surfaces facing each other. Thereby, a container can be hold | maintained firmly in a trunk | drum and the lower end part of a label mounting part.

  Further, the container transport system stops the movement of the two sets of rotating belts based on the detection of the containers by the container detecting means, holds the containers with the two sets of rotating belts, and stops the containers at the stopped positions. And a control device for releasing the stop of the two sets of rotating belts and resuming the movement under a predetermined release condition. Thereby, since a container is hold | maintained firmly in a predetermined stop position, a label can be mounted | worn stably.

  Further, in the container transport system, at least one set of the rotating belts has a holding claw portion that holds the outer periphery of the container, so that the accuracy of the stopping position can be improved.

  In addition, since the container transport system includes a width adjusting unit that varies the width interval arranged in parallel for each set of rotating belts, the interval between each set of rotating belts can be changed even if the dimensions of the container are changed. Since only the change is necessary, it is possible to flexibly cope with the change of the container to be conveyed.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following, a plastic bottle having a round body as a conveyance target will be described, but the outer shape is not limited to this. Moreover, a container made of a material other than plastic, for example, a glass container or a metal container may be used. Moreover, although it demonstrates using a cylindrical heat-shrinkable film as a label which covers a container, other cylindrical labels with an adhesive agent, a cylindrical packaging bag, a sheet label, etc. may be sufficient. Further, although a belt conveyor is used for transporting the containers, other transport means such as a moving carrier may be used. In addition, one set of rotating belts is described as two sets of rotating belts arranged along the conveyance direction so as to sandwich the container, but the respective rotating shafts are arranged at different positions. The rotation shafts of the two sets of rotating belts may be shared. For example, when the lower body portion of the container and the upper label mounting portion have the same outer shape, a two-stage belt can be hung on the same rotating shaft. Further, depending on the shape of the container, three or more sets of rotating belts may be used, and other container holding means may be used in addition to the two sets of rotating belts.

  FIG. 1 is a diagram for explaining the outline of the transport mechanism of the container transport system 10. FIG. 2 is an overall configuration diagram of the container transport system 10. The container transport system 10 includes a transport mechanism unit 20 and a control device 70 that controls the operation of each element constituting the transport mechanism unit 20 as a whole. Here, although not a component of the container transport system 10, a plastic bottle is shown as the container 8 that is the object to be transported, and a cylindrical heat-shrinkable film 6 is shown as what is covered on the container 8. Yes. In FIG. 1, for the purpose of explaining the outline, illustration of some components is omitted, and only two containers 8 at representative positions are illustrated for the containers 8 being transported.

  The container transport system 10 sequentially transports a plurality of containers 8 in the transport direction indicated by the arrows, temporarily stops transport at a position where the heat-shrinkable film 6 is put, and covers the container 8 with the heat-shrinkable film 6 at the stop position. After that, the container 8 has a function of starting conveyance again.

  The transport mechanism unit 20 includes a transport belt conveyor 22, a pair of timing screws 30 arranged in parallel along the transport direction on both sides of the container transport path, and both sides of the container transport path on the downstream side of the pair of timing screws. Two sets of rotating belts 40, 42, 50, 52 arranged in parallel along the conveying direction, a position detection sensor 24 for detecting the position of the container, and a cylindrical heat-shrinkable film as a label on the container 8 6 and a mounting device 36 for mounting 6.

  The conveyor belt conveyor 22 is a continuous body that moves in the direction of the arrow, and has a function of conveying the container 8 in an upright state. The conveyor belt conveyor 22 is driven to move by a motor or the like not shown.

  The pair of timing screws 30 is composed of two timing screw shafts 32 and 34 sandwiching the container conveyance path, and is a container guide mechanism that guides and feeds the container at a predetermined conveyance pitch along the container conveyance path. The timing screw shafts 32 and 34 can be transported with the container 8 sandwiched between the spiral grooves facing each other by rotating in the opposite directions and being driven and rotated in opposite directions. The timing screw shafts 32 and 34 have spiral grooves with a constant pitch, and the spiral grooves advance at a constant speed in the axial direction by rotating at a constant speed in the axial direction. Therefore, by transporting the container 8 using the pair of timing screws 30, the container 8 can be transported at equal intervals more accurately in terms of time and distance than transport by the transport belt conveyor 22. This makes it possible to accurately execute contents injection, label attachment, counting, and other processing even when the conveyance speed is high.

  The two sets of rotating belts 40, 42, 50, and 52 are temporarily stopped while the container 8 is being transported, that is, the container 8 is temporarily stopped at the stop position without stopping the operation of the transport belt conveyor 22 and the pair of timing screws 30. It has a function to make it. By temporarily stopping the container 8 at the stop position, difficult processing can be performed when the container 8 is moving. In the example of FIG. 1, a case where the container 8 is covered with a cylindrical heat-shrinkable film 6 as a label is shown using a label mounting device 36. When the container 8 is moving, the cylindrical label is not covered well with the container 8, so the stop position of the container 8 is set directly below the supply position of the heat-shrinkable film 6.

  For this purpose, two sets of rotating belts 40, 42, 50, 52 are provided on the downstream side of the pair of timing screws 30. Then, the containers 8 that have been transported at a constant high speed by the pair of timing screws 30 are received in the transport gap in the transport direction formed by the rotation of the two sets of rotating belts 40, 42, 50, 52. Receipt is performed by sandwiching the outer peripheral side surfaces of the lower body and upper neck of the container 8 with opposing belts. The position sandwiched by the belt at the neck is preferably immediately below the upper region of the container where the cylindrical label is mounted, that is, the lower end of the upper label mounting portion of the container. Then, the container 8 is moved in the transport direction, and when the two stop belts 40, 42, 50, 52 are stopped when the predetermined stop position is reached, the outer peripheral side surfaces of the body and neck of the container 8 are stopped there. In the held state, the movement of the container 8 is stopped, and the container conveyance is stopped. At this stop position, the cylindrical heat-shrinkable film 6 is supplied from the label mounting device 36 and is covered from above the container 8 as a label.

  The two sets of rotating belts 40, 42, 50, 52 having such a function include one set of rotating belts 40, 42 for holding the body of the container 8 and 1 for holding the neck of the container 8. It is composed of a pair of rotating belts 50 and 52. Each of the rotating belts 40, 42, 50, and 52 can be circulated and moved between two shafts arranged at intervals along the conveying direction, and the outer circumference of the container 8 can be brought into surface contact with the opposite belts. Can be held.

  In FIG. 2, among the pair of rotating belts 40, 42 on one side for holding the body of the container, the rotating belt 40 has an annular belt 44 and two shafts provided on both sides of the annular belt 44. 46 and 48 are shown. Here, the two shafts 46 and 48 have an axial direction perpendicular to the conveying direction, and the belt surface of the annular belt 44 is perpendicular to the conveying surface of the conveying belt conveyor 22. The two shafts 46 and 48 are drive shafts of the belt 44, and at least one of them is driven by a motor (not shown), and can be rotated and stopped at accurate timing under the control of the control device 70. Similarly, the other rotating belt 42 includes an annular belt and two shafts. Each rotary belt 40, 42, 50, 52 can be provided with, for example, an appropriate tension shaft as a means for adjusting the tension of each annular belt.

  Similarly, in FIG. 2, among the pair of rotating belts 50, 52 on the other side for holding the neck of the container, the rotating belt 52 is provided with an annular belt 55 and two sides of the annular belt 55. Two axes 57, 59 are shown. Here, the two shafts 57 and 59 have an axial direction perpendicular to the transport direction, and the belt surface of the annular belt 55 is perpendicular to the transport surface of the transport belt conveyor 22. The same as in the case of the belt 40. The two shafts 57 and 59 are drive shafts of the belt 55, and at least one of them is driven by a motor (not shown) and can be rotated and stopped at an accurate timing under the control of the control device 70. This is the same as in the case of the rotating belt 40. Similarly, the other rotary belt 50 includes an annular belt and two shafts.

  Each of the rotating belts 40, 42, 50, 52 is separated from the transport surface by a suitable support portion (not shown) so as not to interfere with the transport movement of the transport belt conveyor 22, and is predetermined with respect to the container transport path. Arranged in an arrangement relationship. As will be described later, the width interval between the rotating belts 40 and 42 and the width interval between the rotating belts 50 and 52 can be adjusted according to the shape of the container 8. Further, as described above, each of the rotating belts 40, 42, 50, 52 is driven to rotate synchronously under the control of the control device 70 by a motor that is a driving device (not shown).

  As a result, the distance between the belts facing the rotating belts 40 and 42 is matched with the outer shape of the body of the container 8, and the distance between the belts facing the rotating belts 50 and 52 is matched with the outer shape of the neck of the container 8. The belt can be brought into surface contact with the side surface, and the four belts can be synchronously moved, so that the container 8 can be transported with the surface contact between the four locations. Further, by stopping the four belts synchronously, even if the conveyor belt conveyor 22 is moving, the container 8 sandwiched between the belts can be stopped separately from the movement.

  FIG. 2 shows a state in which six containers 8 are sequentially conveyed in the direction of the arrow. The six containers 8 are sandwiched between timing screw shafts 32 and 34, which are in a state of being conveyed upright on the conveyor belt conveyor 22 along the conveying direction from the left side to the right side in FIG. 2. 2 in the state of being conveyed, and one in the state of being conveyed upright by the conveyor belt conveyor 22 again after being brought to an accurate conveyance pitch state by the timing screw shafts 32 and 34, the rotating belts 40, 42, One of the states held by the stopping positions 50 and 52, one covered with the tubular heat-shrinkable film 6 at the stopping positions, and again conveyed upright by the conveyor belt conveyor 22 are shown. Yes.

  The position detection sensor 24 is a container detection unit having a function of detecting the position of the container 8 on the downstream side of the timing screw shafts 32 and 34. The position where the position detection sensor 24 detects the container 8 is set in association with a stop position where the container 8 is held and stopped by the two sets of rotating belts 40, 42, 50, 52. For example, the presence / absence of the container 8 is detected at a position going back a predetermined transport distance upstream from the stop position. In FIG. 2, the position detection is performed to determine whether or not the container 8 in the state of being conveyed upright by the conveyor belt conveyor 22 again after being brought into an accurate conveyance pitch state by the timing screw shafts 32 and 34. It is detected by the sensor 24. As such a position detection sensor, an optical sensor such as an infrared sensor, an ultrasonic sensor using reflection of ultrasonic waves, or the like can be used.

  When the position detection sensor 24 detects that the container 8 has reached a predetermined detection position, a detection signal is transmitted to the control device 70. As will be described later, when the control device 70 receives a signal indicating that the container 8 has arrived at the detection position from the position detection sensor 24, an operation command is sent to the drive device that drives the rotating belts 40, 42, 50, 52. Put out. This operation command is to rotate the rotating belts 40, 42, 50, 52, and to convey the containers 8 conveyed by the belts facing each other. , 50, 52 are stopped, and control is performed so that the container 8 is stopped here. This timing is set based on the arrangement relationship between the detection position of the container 8 and the stop position.

  The mounting device 36 is a device for supplying the tubular heat-shrinkable film 6 as a label to the container 8 held at the stop position by the stopped rotating belts 40, 42, 50, 52. The mounting device 36 is provided above the rotating belts 40, 42, 50 and 52, and supplies the tubular heat-shrinkable film 6 downward to the mounting position of the neck portion of the container 8 in the stationary position. Cover. The timing at which the mounting device 36 supplies the heat-shrinkable film 6 is managed under the control of the control device 70.

  That the heat shrinkable film is attached to the container 8 by the attachment device 36 is detected by an attachment detection means (not shown). A signal indicating that the mounting is completed is transmitted to the control device 70, whereby the stop command for the rotating belts 40, 42, 50, 52 is released, and the container 8 is held between the rotating belts 40, 42, 50, 52. The transfer is performed again. In addition, it is also possible to cancel the stop command for the rotating belts 40, 42, 50, 52 after a predetermined time elapses after the rotating belts 40, 42, 50, 52 stop without providing the mounting detection means. Good.

  The control device 70 has a function of controlling the operation of each element constituting the transport mechanism unit 20 as a whole and transporting the container 8 at a predetermined transport speed. Here, in particular, the movement of the two sets of rotating belts 40, 42, 50, 52 is stopped and the two sets of rotating belts 40, 42, The containers 8 are held and stopped at 50 and 52, labels are attached to the containers 8 at the stopped positions, and the two sets of rotating belts 40, 42, 50 and 52 are stopped under a predetermined release condition. Has a function of canceling and restarting the movement.

  In addition to the conveyance processing unit 80 that performs general conveyance processing, the control device 70 includes a container detection unit 72 that detects that the container 8 has reached a predetermined detection position, and a container based on the detection of the container 8. 8 is temporarily stopped and stopped at the stop position, a stop processing unit 74 for attaching the label to the container 8 at the stop position, and the transport stop process is canceled after the mounting is completed, and the container 8 is returned again. It is configured to include a release processing unit 78 for transporting.

  The control device 70 can be configured by a computer or a dedicated control device. Moreover, each said function is realizable with software, and can be specifically implement | achieved by running a container conveyance control program. Some of the above functions may be realized by hardware.

  The operation of the above configuration, particularly each function of the control device 70, will be described in detail with reference to the flowchart of FIG. FIG. 3 is a flowchart showing a procedure of container conveyance, particularly a procedure of temporary container conveyance stop processing, and each procedure corresponds to each processing procedure of the container conveyance control program.

  In order to carry a container, preparations for the container are performed. In other words, the pair of timing screws 30 and the replacement arrangement are selected according to the dimensions of the container 8 to be conveyed (S10). And the space | interval between the belts which face in rotation belt 40,42,50,52 is adjusted (S12).

FIG. 4 is a diagram for explaining that the distance between the rotating belts 40, 42, 50, and 52 varies depending on the shape of the container. On the left (a), a small container 8 is shown. In this case, the distance between the belts 44 and 45 facing each other at the trunk is W ₁ , and between the belts 54 and 55 facing each other at the neck. Is B ₁ , and the height positions of the belts 54 and 55 at the neck are H ₁ . Here, the height position H ₁ is the position of the lower end portion of the label mounting portion. On the other hand, a large container 9 is shown on the right side (b). In this case, the distance between the belts 44 and 45 facing each other at the trunk is W ₂ and the distance between the belts 54 and 55 facing each other at the neck. Is B ₂ , and the height positions of the belts 54 and 55 at the neck are H ₂ .

Therefore, when stopping control of the containers 8 and 9 is performed using the rotating belts 40, 42, 50, and 52, when the shapes and dimensions of the containers 8 and 9 are changed, the rotating belts 40, 42, and 50 are changed. , 52 need only be changed. In particular, when W ₁ = B ₁ and W ₂ = B ₂ , it is only necessary to adjust the width intervals of the rotating belts 40, 42, 50, 52. Needless to say, the arrangement relationship of the rotating belts 40, 42, 50, and 52 can be manually changed, but can also be changed by using an actuator as an arrangement relationship adjusting unit. For example, the arrangement relationship of the rotating belts 40, 42, 50, and 52 can be changed only by the operation using a changeover switch or a changeover button. Furthermore, it is good also as what detects the shape of a container 8, 9, a dimension, etc., and changes the arrangement | positioning relationship of each rotating belt 40, 42, 50, 52 automatically according to the result. In the case where only the adjustment of the width interval of the rotating belts 40, 42, 50, 52 is sufficient, the arrangement relationship adjustment unit corresponds to a width adjustment unit that adjusts the width interval.

  Returning to FIG. 3 again, in S10 and S12, for example, when preparations such as replacement of the pair of timing screws 30 with respect to the container 8 and adjustment of the arrangement relationship of the rotary belts 40, 42, 50, and 52 are completed, the container transport system 10 is completed. The container transfer control program is launched at the start of And the container 8 is carried in from the upstream of a conveyance path (S20). First, the container 8 is conveyed in a standing state on the conveyor belt conveyor 22 (S22). And the conveyance by a pair of timing screw 30 is performed, and the conveyance pitch of each container 8 is correctly aligned (S24). Thereafter, the conveyor belt conveyor 22 is once transported (S26). The steps so far are executed by the function of the transfer processing unit 78 of the control device 70.

  Then, using the position detection sensor 24, it is determined whether or not the container is detected based on whether or not the transport position of the container 8 has reached a predetermined detection position (S28). This determination is executed by the function of the container detection unit 72 of the control device 70.

  If it is determined that the container 8 has been detected, conveyance by the rotating belts 40, 42, 50, and 52 is performed (S30). Then, the rotation belts 40, 42, 50, and 52 are deactivated at a position moved by a predetermined distance based on the positional relationship between the container detection position and the stop position (S32). As a result, even if the conveyor belt conveyor 22 is moving, the container 8 is held between the belts facing each other, and takes a pause position accurately at the stop position. Thus, since the positioning for covering the heat-shrinkable film 6 is accurately performed at the stationary position, the processing time for covering the heat-shrinkable film 6 can be effectively shortened. This step is executed by the function of the stop processing unit 74 of the control device 70.

  When the container 8 stops at the stop position, label mounting is performed next (S34). This step is executed by the function of the mounting processing unit 76 of the control device 70. Confirmation that the container 8 stops at the stop position is performed by moving a predetermined distance from the container detection as described above, but a detection means for detecting the container stop may be further provided. For example, the mounting device 36 may be provided with means for detecting whether or not the container 8 is stopped at the stop position. Label mounting can be performed by supplying the cylindrical heat-shrinkable film 6 from the mounting device 36 toward the neck of the container 8 below.

  Next, it is determined whether or not the mounting is completed (S36). As described above, this determination is made by detecting whether or not the heat-shrinkable film 6 is covered on the container 8 using the mounting detection means. Further, without the mounting detection means, it may be determined that the mounting is completed when a predetermined time elapses after the rotating belts 40, 42, 50, 52 are stopped. When it is determined that the attachment is complete, the stop command for the rotating belts 40, 42, 50, 52 is released (S38). When the stop is released, the rotating belts 40, 42, 50, and 52 start to operate again, the container 8 is released from the stationary state, and is conveyed by the rotating belts 40, 42, 50, and 52. This step is executed by the function of the release processing unit 78 of the control device 70. When the transport range of the rotary belts 40, 42, 50, 52 is passed, the container 8 is transported again by the transport belt conveyor 22 (S40) and is transported to the next process (S42).

  In this way, using the rotating belts 40, 42, 50, and 52, the conveyance of the container 8 can be temporarily stopped at the stopping position in the accurate positioning state, and the label can be mounted in that state.

  In the above description, it has been described that the container 8 is held by the surface contact of the rotating belts 40, 42, 50, and 52, and the position at the conveyance and stop positions is fixed. Further, as a means for ensuring the holding, a holding claw portion for holding the outer periphery of the container 8 can be provided on the belt.

  FIG. 5 is a view showing an example in which holding claw portions 93, 94, 95, and 96 are provided on the rotating belts 41 and 43 on one side that sandwich the body portion of the container 8. Two holding claws are provided on each of the rotating belts 41 and 43. That is, two holding claw portions 93 and 94 are provided on the rotating belt 41, and two holding claw portions 95 and 96 are provided on the rotating belt 43. The distance between the two holding claws 93 and 94 in the rotating belt 41 and the distance between the two holding claws 95 and 96 in the rotating belt 43 are set to dimensions that can firmly hold the outer shape of the body portion of the container 8. Is set. Since the rotating belts 41 and 43 are synchronously driven by the control device 70, the holding claw portion 93 is first set by correctly setting the relative positional relationship of the holding claw portions 93, 94, 95 and 96 on the rotating belts 41 and 43. , 94, 95, and 96, the container 8 can be accurately held in the standing posture.

  Similarly, a holding claw portion can be provided on each of the other rotating belts for holding the neck portion of the container 8. As in FIG. 5, if two holding claws are provided on each of the other rotating belts, the container 8 is supported at four points on the trunk and at four points on the neck. Become. By these eight holding claws, the standing posture of the container 8 is correctly secured with good reproducibility, and the position when the heat-shrinkable film 6 is covered can be accurately secured.

  In the above, in order to guide and send the container 8 along the container conveyance path at a predetermined conveyance pitch, a pair of timing screws 30 arranged in parallel along the conveyance direction on both sides of the container conveyance path are used. explained. As another container guide mechanism, a combination mechanism of one timing screw shaft 34 and a feed belt 90 facing the timing screw shaft 34 shown in FIG. 6 may be used. Alternatively, a combination mechanism of the star wheel 92 and the feed belt 90 facing the star wheel 92 shown in FIG. 7 can be used.
