Description

  The present invention relates to a bag receiving structure of a packaging device.

  In a packaging apparatus for bagging, in order to fill a bag with liquid or solid contents, a bag receiver is provided at a constant interval on the conveyor, and the upper part is closed in the upstream process in the bag receiver. The bag body is stored, and the stored bag body is transported to the next process. In the process, the bag mouth of the bag body is pulled from both sides by a sucker, and air is sent into the bag body to remove the bag body from the contents. Expansion is performed so as not to hinder filling, and then the contents are filled, and an example thereof is disclosed in Japanese Patent Application Laid-Open No. 2001-341702.

  However, in the packaging device disclosed in Japanese Patent Application Laid-Open No. 2001-341702, when opening the bag body, a vacuum device is necessary for adsorbing the suction cup to the bag body, and an air supply source is used to blow air into the bag body. is required. As a result, in the conventional packaging apparatus, various apparatuses are required, and therefore, the apparatus is complicated and large, and there is a risk of increasing the cost.

  Therefore, in order to solve these problems, the applicant of the present application, as of February 3, 2006, used a packaging device that does not require a vacuum device or an air supply source as a bag body opening jig for opening the bag body. (Japanese Patent Application No. 2006-27190) has been proposed, and in this packaging apparatus, a pair of bag body opening jigs that can be moved close to and away from the bag body are made of adhesive plastic such as urethane elastomer instead of a suction cup.

  Thus, in the packaging device of Japanese Patent Application No. 2006-27190, the bag body opening jig attached to the bag body is moved away from each other to open the bag body, and then the charging funnel is lowered and the bag is opened. After inserting into the body, the contents are put into the bag through the charging funnel, and then the bag opening jigs facing each other are moved away from each other to peel the bag opening jig from the bag. After that, the charging funnel is raised from the bag.

  In the packaging device of Japanese Patent Application No. 2006-27190, the bag body is a bag body so that the bag body opening jig does not interfere with the bag body receptacle when the bag body opening jig is attached to or removed from the bag body. The bag body opening jig extends above the upper end of the receiver, and is attached to the bag body above the bag body receiver.

  In the packaging device of Japanese Patent Application No. 2006-27190, when the pair of bag body opening jigs are moved away from each other and peeled from the bag body, either the left or right bag body opening jig is peeled off from the bag body. Even if the bag body on the side to which the bag body opening jig is attached is pulled by the bag body opening jig, the movement of the bag body on the side to which the bag body opening jig is not attached is restricted by the charging funnel. Therefore, the charging funnel functions as a stopper, and as a result, the bag body opening jig can be peeled off from the bag body, and the packaging operation can be performed smoothly.

  By the way, in some packaging devices, the contents are put into the bag body without using the charging funnel. However, in order to open the bag body with such a device, the bag body opening treatment made of adhesive plastic is used. When the tool is used, the bag opening jig may not be peeled off from the bag even if the bag opening jig is moved away from each other. Therefore, in order to securely peel the bag body opening jig from the bag body, the height of the bag body receiver is made higher than the bag body so that it can be used as a jig for peeling the bag body opening jig from the bag body. It has been proposed. However, if the bag body opening jig is made higher than the bag body, the operation of the bag body opening jig is hindered and the work cannot be performed smoothly.

  In view of such circumstances, the present invention is designed so that the bag body receptacle can be easily and reliably peeled off from the bag body even when a charging funnel for charging contents into the bag body is not used. To provide a bag receiving structure for a packaging device that does not hinder the operation of the bag opening jig even when the height is higher than that of the bag so that it can be used as a jig for peeling off the bag. It was made for the purpose.

  The bag receiving structure of the packaging device according to claim 1 of the present invention is made of a pair of adhesive plastics capable of opening and closing to open the bag when the contents are supplied to the bag stored in the bag receiving. In the packaging apparatus provided with the bag body opening jig, a hole through which the bag body opening jig can pass when the bag body opening jig opens and closes is formed in the bag body receptacle. In this bag body receiving structure, the bag body receiver is higher in height than the bag body.

  According to the bag body receiving structure of the packaging device according to claims 1 and 2 of the present invention, when the bag body opening jig passes through the hole of the bag body receiving body, the bag body is moved by the inner surface of the bag body receiving body. As a result of being regulated, the bag body opening jig can be easily and reliably peeled off, and an excellent effect that a highly reliable packaging operation can be performed can be achieved.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
1-10 is an example of the form which implements this invention.
In the figure, reference numeral 1 denotes a guide stand installed on a frame not shown. On the guide stand 1, two solid arrows a 'and b' and two dotted arrows a "and b" in FIG. As shown by "", elongated lever-like swinging members 2 and 3 that can move (swing) in directions opposite to each other are arranged in parallel so as to be positioned in a direction perpendicular to the moving direction. In addition, a plurality of guide pins 4 are attached to the guide stand 1 so as to be able to guide the widthwise outer portions of the swing members 2 and 3 that are arranged in parallel but not facing each other.

  The front ends of the swing members 2 and 3 are bent downward to form support plate mounting portions 2a and 3a, and the front ends of the support plates 5 and 6 attached to the support plate mounting portions 2a and 3a in the horizontal direction. The bag body opening jigs 9 and 10 are opposed to each other through the brackets 7 and 8 so as to be close to and away from each other. The bag opening jigs 9 and 10 are made of adhesive plastic such as urethane elastomer, but any plastic is applicable as long as it is adhesive plastic. The opposing surfaces of the bag body opening jigs 9 and 10 are bag body attachment surfaces 9a and 10a.

  At the rear ends of the oscillating members 2 and 3, elongated holes 2b and 3b extending in a direction perpendicular to the oscillating direction of the oscillating members 2 and 3 in plan view are formed so as to be parallel to the oscillating direction. Yes. A support plate 11 (see FIGS. 1 and 3) is disposed on the upper surface of the rear end portions of the swing members 2 and 3, and the output of the vertical reduction motor 12 installed on the support plate 11. A drive gear 13 is externally fitted and fixed to the shaft 12 a so as to be positioned on the lower surface of the support plate 11, and a driven gear 14 installed on the lower surface of the support plate 11 is engaged with the drive gear 13.

The driven gear 14 is disposed at a position in the swing direction of the swing members 2 and 3 with respect to the drive gear 13 and at a position on the bag body opening jigs 9 and 10 side, and the drive gear 13 and the driven gear 14. The pins 15 and 16 are protruded downward so that the bag opening jigs 9 and 10 are located closest to each other in the swinging direction when the bag body opening jigs 9 and 10 are separated from each other. 16 is inserted into the long holes 2b and 3b (see FIGS. 1 and 2).
ing.

  The bag supply apparatus which supplies a bag between the bag opening jigs 9 and 10 in an automatic packaging machine is shown in FIG. The bag supply device includes, for example, a belt conveyor 18 having a conveyor belt 17 that can move in a direction orthogonal to the paper surface in FIG. 1, and the conveyor belt 17 has a constant interval in the moving direction, A bucket-shaped bag receiver 20 for storing the bag 19 is attached.

  Thus, the height H1 of the bag receiver 20 is higher than the height H2 of the bag receiver 19, and there are two openings in the circumferential direction of the bag receiver 20 at positions facing each other. A hole 20a (see FIG. 1 and the like) is provided so that the bag opening jigs 9 and 10 can pass when the opening operation is performed.

  Next, the operation of the above-described embodiment will be described with reference to FIGS. 4 (a), 4 (b) to 9 (a), and 9 (b). Thus, when starting the operation of opening the bag body 19 with the bag body opening jigs 9 and 10 of the automatic packaging machine and supplying the contents to the bag body 19, as shown in FIG. The bag opening jigs 9 and 10 are in the most open state with the interval W, and the pin 15 of the drive gear 13 and the pin 16 of the driven gear 14 are in the closest state as shown in FIG. As shown in FIG. 2, the rocking members 2 and 3 are arranged in the middle of the longitudinal direction of the long holes 2b and 3b.

  The bag body holder 20 in which the bag body 19 is accommodated so that the upper end is accommodated in the bag body receiver 20 is conveyed in a direction orthogonal to the paper surface by the belt conveyor 18 of the bag body supply device, and the bag body opening jigs 9, 10. When it comes in between (see FIG. 5A), the belt conveyor 18 stops. At this time, since the drive gear 13 is stopped, the positions of the pin 15 of the drive gear 13 and the pin 16 of the driven gear 14 are unchanged (see FIG. 5B).

  When the bag body holder 20 in which the bag body 19 is stored is stopped between the bag body opening jigs 9 and 10, the reduction motor 12 is driven and the drive gear 13 is rotated counterclockwise in FIG. And about 180 degrees (see FIG. 6B). For this reason, the driven gear 14 is rotated 180 degrees clockwise (arrow B direction) in FIG. 5B by the drive gear 13 (see FIG. 6B).

  Thus, when the drive gear 13 and the driven gear 14 are rotated from the position of FIG. 5B in the direction of arrow A and B, the swing member 2 is linearly moved in the direction of the solid arrow A ′ in FIG. Since the member 3 moves linearly in the direction of the solid arrow B ′ in FIG. 2, the bag body opening jigs 9, 10 move through the holes 20 a, 20 a of the bag body receiver 20 so as to be closest to each other. The body attachment surfaces 9a and 10a adhere to the vicinity of the outer upper edge portion of the bag body 19 (see FIG. 6A). In this case, the pins 15 and 16 slide in the longitudinal direction from the central portion of the long holes 2b and 3b, and return to the central portion again through the end portion shown on the lower side in FIG.

  When the bag body opening jigs 9 and 10 are attached to the bag body 19 and the drive gear 13 and the driven gear 14 are further rotated 120 degrees in the direction of arrow A and B from the position of FIG. b)), since the swinging members 2 and 3 linearly move in the directions of dotted arrows “a” and “b” in FIG. 2, the bag opening jigs 9 and 10 move away from each other. For this reason, the upper edge side of the bag body 19 is opened by the bag body opening jigs 9 and 10 (see FIG. 7A). In this case, the pins 15 and 16 slide in the longitudinal direction from the central portions of the long holes 2b and 3b, and are positioned above the central portion in plan view in FIGS. 2 and 7B.

  As shown in FIG. 7A, when the upper end portion of the bag body 19 is opened, the contents 21 are put into the bag body 19 and filled with appropriate means (see FIG. 8A). In this case, the drive gear 13 and the driven gear 14 are stopped.

  When the bag body 19 is filled with a predetermined amount of the contents 21, the driving gear 13 and the driven gear 14 are rotated 60 degrees in the direction of arrow a and b from the state of FIG. Return to the original position (see FIG. 9B). At this time, the bag body opening jigs 9 and 10 move in the directions indicated by the dotted arrows “a” and “b” in FIG. 2, and retreat through the holes 20 a of the bag body receiver 20. Accordingly, the bag body opening jigs 9 and 10 are separated from the bag body 19 and returned to the original position where the interval W is farthest (see FIG. 9A).

  Even when the bag body 19 is attached to the bag body opening jigs 9 and 10 when the bag body opening jigs 9 and 10 are opened so as to be separated from each other, the bag body opening jigs 9 and 10 are attached to the bag body receiver 20. When passing through the hole 20a, the bag body 19 comes into contact with the inner surface of the bag body receiver 20, and the bag body 19 cannot move further in the opening direction. For this reason, the inner surface of the bag body receiver 20 functions as a jig for peeling the bag body 19 from the bag body opening jigs 9, 10. As a result, the bag body 19 can be easily removed from the bag body opening jigs 9, 10. It is reliably peeled off and a highly reliable packaging operation can be performed.

  When the filling of the contents 21 into the bag body 19 is completed, the bag body 19 filled with the contents 21 is conveyed by the belt conveyor 18 from the position of the bag body opening jigs 9 and 10 to the downstream side. Sealing is performed and the bag body 20 is taken out.

  In the illustrated example, since the bag opening jigs 9 and 10 made of adhesive plastic are used to open the bag body 19, a vacuum device and an air supply source are not necessary, thereby simplifying the device. In addition, the cost can be reduced, and when the bag body opening jigs 9 and 10 pass through the holes 20a of the bag body receiver 20, the inner surface of the bag body receiver 20 functions as a stopper. Since the bag body 19 is easily and reliably peeled from the bag body opening jigs 9 and 10, a highly reliable packaging operation can be performed.

  Note that the bag receiving structure of the packaging device of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention.
