  By the way, in a conventional apparatus that detects a specific part of a container conveyed by a belt conveyor with a sensor and identifies the position of the container in consideration of the conveyance speed of the belt conveyor, and operates a straw sticking means. There is a problem that the attachment position of the straw wrapping body with respect to the container fluctuates due to the detection error of the sensor and the transfer speed by the belt conveyor, and the appearance of the container deteriorates due to the adhesive sticking out. In addition, if the conveyor speed of the belt conveyor is increased to increase the processing speed, the error of the sensor and the variation of the conveyor speed also increase, and the variation in the attachment position of the straw package relative to the container becomes even greater. Therefore, the processing speed cannot be set so high in the conventional apparatus, for example, the processing speed of about 200 / min is the limit.

  In addition, even if the posture of the container on the belt conveyor is not stable, the attachment position of the straw wrapping body with respect to the container varies, which causes the appearance of the container to deteriorate. Further, particularly when a rectangular parallelepiped container is conveyed by a belt conveyor, when a plurality of containers are conveyed in close contact with each other, one container cannot be detected by the sensor, and the straw package is attached to the container. There was also a problem that was not stuck.

  Therefore, an object of the present invention is to provide a straw sticking device that can be attached to a straw packaging body at an appropriate position on the side surface of the container with high accuracy and can greatly increase the speed of the sticking process of the straw packaging body. That is.

  That is, the present invention is a straw adhering device comprising a container conveying means for conveying a container, and a straw adhering means for adhering a straw package to the side surface of the container in the middle of conveying the container by the container conveying means. In addition, a belt conveyor for conveying the container while supporting the container from below is provided as the container conveying means, and the containers conveyed by the belt conveyor are held in the screw grooves one by one, and the container is A screw conveyor that sequentially supplies the sticking means with a set interval is provided on the upper side of the belt conveyor, and the straw sticking means is placed in a container held in the screw groove of the screw conveyor. On the other hand, the straw sticking apparatus characterized by sticking a straw packaging body was comprised.

  Here, as the container conveying means, a container which is provided at a position facing the screw conveyor on the upper side of the belt conveyor and has an outer peripheral surface gradually expanding in a spiral shape and conveyed between the screw conveyor What provided the auxiliary screw pushed out to the screw conveyor side by the said outer peripheral surface and fitted in the screw groove of this screw conveyor is preferable.

  In addition, it is preferable that the screw conveyor and the straw sticking means are mechanically interlocked with each other.

  Furthermore, the straw sticking means has an adhesive applying means for applying an adhesive to the side surface of the container, and a straw feed for winding the straw mounting tape containing the straws around the set interval around the outer circumference of the holder member. Means, cutting means for cutting the straw mounting tape wound around the holder member between adjacent straws, and separating the straw packaging body into a straw packaging body containing one straw, and a container holding the separated straw packaging body It is preferable to have a pressing means that presses against the adhesive applied to the side surface.

  A first angle adjusting means for adjusting the angle of the adhesive applying means; and a second angle adjusting means for adjusting the angles of the straw feeding means, the cutting means and the pressing means integrally. It is preferable to attach the straw wrapping body so as to be inclined with respect to the side surface.

  In particular, an apparatus in which the straw feeding means, the cutting means and the pressing means are operated mechanically in conjunction with the screw conveyor via an input shaft coaxial with the support shaft serving as the rotation center of the second angle adjusting means. preferable.

  The present invention can be suitably used in the case of a rectangular parallelepiped container.

  According to the straw sticking apparatus according to the present invention, the containers transported by the belt conveyor are held one by one in the screw groove of the screw conveyor in the middle of the transport, and the set interval is mutually set with respect to the straw sticking means. Since it is opened and sequentially supplied, the transport position of the container held in the screw groove can be accurately grasped in real time based on the rotation angle of the screw conveyor, compared to the device that detects the position of the container using a conventional position sensor. Thus, the straw packaging body can be attached to the appropriate position on the side surface of the container with extremely high accuracy. In addition, since errors in conventional sensors and variations in the conveyance speed do not occur, even if the processing speed is increased, it can be attached with high accuracy, and the processing speed can be significantly improved as compared with the conventional one. It has been confirmed that according to the present invention, it is possible to improve the processing speed to 300 / min with respect to the same container whose processing speed is 200 / min in the conventional apparatus. In addition, even when a plurality of containers are transported in close contact by a belt conveyor, the plurality of containers can be separated one by one by a screw conveyor and transported to a straw pasting means. It is possible to prevent generation of defective containers that are not made. Furthermore, since the straw packaging body can be attached while holding the container in the screw groove, the posture of the container at the time of pasting the straw packaging body is stabilized, and the straw packaging body is accurately attached to the appropriate position on the side surface of the container. It becomes possible to do.

  Further, as the container conveying means, a container which is provided at a position facing the screw conveyor on the upper side of the belt conveyor and has an outer peripheral surface gradually expanding in a spiral shape and conveyed between the screw conveyor and the container The auxiliary screw that is pushed out to the screw conveyor side by the outer peripheral surface and fitted into the screw groove of the screw conveyor is provided, so that even when a rectangular parallelepiped container is conveyed in close contact, for example, each container is placed on the outer periphery of the auxiliary screw. It can be extruded one step at a time depending on the surface, hooked into the screw groove of the screw conveyor, and fitted as it is, so that the conveyance by the screw conveyor can be ensured.

  In addition, since the screw conveyor and the straw sticking means are mechanically interlocked with each other, the precision of the sticking position is remarkably improved, and the processing speed can be greatly increased.

  In addition, since the straw feed means, the cutting means and the pressing means are operated mechanically in conjunction with the screw conveyor via the input shaft coaxial with the support shaft that is the rotation center of the second angle adjusting means, The angle can be adjusted with a simple configuration without complicating the configuration of the drive system. In addition, adjustment of the drive system accompanying angle adjustment is facilitated.

  In the straw sticking device of the present invention, the containers can be sequentially transported with a certain interval between adjacent containers, so it goes without saying that the container is a cylindrical container or a rectangular parallelepiped container. It is possible to reliably attach the straw package.

  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a plan view showing the overall configuration of a straw sticking apparatus according to the present invention, and FIG. 2 is a front view thereof. 1 to 9 show a typical embodiment of the present invention, in which reference numeral 1 is a straw sticking device, 2 is a container transporting means, 3 is a straw sticking means, 4 is a drive mechanism on the container transport means side, Reference numeral 5 denotes a drive mechanism on the side of the straw sticking means, and U denotes a straw sticking unit in which the entire straw sticking means excluding the adhesive applying means is unitized.

  As shown in FIGS. 1 and 2, the straw sticking apparatus 1 includes a container transporting means 2 for transporting a plurality of containers 10,... And a straw on the side surface of the container 10 during the transport of the container 10 by the container transporting means 2. A straw sticking means 3 for sticking the package Ta is provided. The container conveying means 2 is forcibly supported by a belt conveyor 21 that conveys the container 10 while supporting the container 10 from the lower side, and the container 10 to be conveyed is held on the screw groove 22a one by one in the upper side of the belt conveyor 21. And a screw conveyor 22 that sequentially feeds the containers 10 to the straw sticking means 3 in a state of being spaced apart from each other, and the straw packaging body Ta containing one straw S is provided with the straw sticking means. 3 are sequentially attached to the respective containers 10 in the middle of conveyance while being held in the screw grooves 22 a of the screw conveyor 22.

  In the present invention, since the straw packaging body is attached to the container 10 held on the screw conveyor 22 in this way, the position of the container can be recognized accurately and in real time by the rotation angle of the screw conveyor 22, The accuracy of the straw sticking position is remarkably improved compared to the conventional equipment that sticks the straw by estimating the container position based on the speed of the belt conveyor that conveys the container and the sensor that detects the passage of the container. The processing speed can also be increased, and as will be described later, since the operation of the screw conveyor 22 and the operation of the straw sticking means are mechanically interlocked and a mechanism that can synchronize is adopted, It is possible to further increase the accuracy and processing speed.

  In addition, the straw sticking apparatus 1 of this embodiment shows the example comprised as an apparatus which arrange | positions the personnel who supply and take out the container 10 in the upstream and downstream of the belt conveyor 21, and only sticks the straw S. However, the present invention is not limited to this, and it is of course possible to configure the apparatus so as to automatically supply and take out the container 10 or to connect to the container production line online. Further, in this example, the container 10 is held and transported only on one side with respect to the axis of the screw conveyor 22 and is processed in only one row. However, both sides of the screw conveyor 22 are used, or the screw conveyor 22 is used. By providing two or more and two or more straw adhering means 3, it is also possible to provide an apparatus for simultaneously processing two or more rows of containers. Moreover, it is also possible to add a process in which the expiration date is printed on the side surface of the container by the printing device, other processes, and the like in the middle of the belt conveyor 21 and the screw conveyor 22 of the straw sticking apparatus 1.

  The belt conveyor 21 has a known configuration including an endless loop belt that is stretched between a pair of pulleys and driven to circulate. In this example, as will be described later, the container 10 is moved on the belt by the auxiliary screw 24, and the transfer speed of the container 10 by the belt conveyor 21 is slightly slower than the container transfer speed of the screw conveyor 22, thereby separating the containers 10. Since the adjustment can be performed, the surface of the belt on which the container 10 is placed can be slid on the surface of the belt on which the container 10 is placed and the material of the belt itself so that the container 10 can move smoothly on the belt. It is preferable to use a material such as a synthetic resin in consideration of sliding. On the upper side of the belt conveyor 21, side guide rods 23 that are disposed on both front and rear sides of the middle portion of the container 10 in the height direction to prevent the container 10 from falling down and regulate the front and rear positions are provided on the belt conveyor 21. The container 10 is transported on the belt conveyor 21 in a stable posture while being guided by the side guide rod 23.

  The screw conveyor 22 has an axial length extending from a position before the straw sticking means 3 along the belt conveyor 21 to at least a straw sticking position of the straw sticking means 3, and the height of the container 10 at the outer peripheral portion. A screw groove 22a made of a spiral groove capable of receiving and holding the middle part of the direction is formed. Similarly, an auxiliary screw 24 for fitting the container 10 conveyed before the screw conveyor 22 into the screw groove 22a of the screw conveyor 22 is provided in parallel at a position facing the screw conveyor 22 on the upper side of the belt conveyor 21. It has been. The container 10 held on the screw conveyor 22 is transferred to the position of the straw sticking means 3 at set intervals by the belt conveyor 21 and the screw conveyor 22 while the interval is adjusted in the transfer direction. Since these screw conveyors 22 and auxiliary screws 24 need to generate a good slip between the container 10 and the container 10, the surface treatment that causes the good slip and the material itself may be made of a synthetic resin having a good slip. preferable. The screw groove 22a is formed in a square groove shape so that the rectangular parallelepiped container 10 can be stably held. However, when conveying a container of a shape other than a rectangular parallelepiped, the groove is adapted to the cross-sectional shape of the container to be conveyed. Can be configured in shape.

  The auxiliary screw 24 has an outer peripheral surface 24b that expands in a spiral shape, and is driven synchronously with the screw conveyor 22. The container 10 is gradually pushed out to the screw conveyor 22 side by the outer peripheral surface 24b, and into the screw groove 22a. Each container 10 is inserted, and the container 10 is sandwiched between the screw conveyor 22 and transferred. Due to the presence of the auxiliary screw 24, for example, even when the rectangular parallelepiped container 10 flows continuously without a gap, the container 10 is pushed by the outer peripheral surface 24b and protrudes laterally from the continuous row one by one. 22 can be engaged with the screw groove 22a and can be securely fitted into the screw groove 22a. In addition, it is also possible to comprise so that the container which flowed by the guide plate etc. may be inserted in the screw groove 22a instead of such an auxiliary screw 24, and the screw conveyor 22 is replaced with the auxiliary screw 24.

It is comprised so that the container 10 hold | maintained at the screw groove 22a can be conveyed with the stable attitude | position which closely_contact | adhered without removing from the screw groove 22a. In the present invention, the straw is stuck in a state where the container 10 is held in the screw groove 22a, and it is necessary to stably hold the container 10 in the screw groove 22a. Here, the side guide member 23A is formed of a plate-like member, but the above-described side guide rod 23 may be provided. In addition, the side guide member 23A is provided up to the position where the straw is attached, and from there, the side guide rod 23 is provided, but it is not particularly limited to such a structure, Other guide structures may be used as long as the guide means can transfer the container 10 in a stable posture held in the screw groove 22a with a structure that does not interfere with the straw sticking means 3. The transfer speed by the belt conveyor 21 is set to be slightly higher than the transfer speed by the screw conveyor 22 so that the container 10 can be reliably transferred to the position of the straw sticking means 3 in the screw groove 22a of the screw conveyor 22 in a stable posture. It is configured.
