Description

  The present invention relates to a gripping device that grips a bottle and an inter-path transfer device.

An operation of continuously casing a bottle such as a PET bottle on a cardboard or the like is performed using a gripping device or an inter-road transfer device that grips the bottle (see, for example, Patent Document 1).
For example, as illustrated in FIG. 13, the inter-way transfer device 100 includes a main body 101 and a gripping device 103. A plurality of gripping devices 103 are provided, and the plurality of gripping devices 103 are connected by a connecting portion 104. The connecting portion 104 and the main body portion 101 are connected by an arm 102. The arm 102 is driven by a driving unit provided in the main body unit 101 and moves the gripping device 103 up and down and left and right via the connecting unit 104.
As shown in FIG. 14, the gripping device 103 includes a pair of gripping portions 105 that grip the narrow diameter portion (upper end portion) HO of the bottle PB. In addition, in FIG. 14, the code | symbol CA shows the cap and the code | symbol YO has shown the container main-body part.

The casing operation of the bottle PB is performed as follows, for example.
First, the bottle PB is continuously transported in the transport direction A by being placed on the bottle transport path L1. When the bottle PB is stopped at a predetermined position on the bottle conveyance path L1, the bottle PB is conveyed to the cardboard conveyance path L2 while being held by the holding device 103. At this time, an empty cardboard DB is arranged on the cardboard conveyance path L2, and the bottle PB is arranged inside each cardboard DB. Further, the cardboard DB in which the bottle PB is placed is transported in the transport direction B on the cardboard transport path L2, and the lid is closed.
Thereby, the bottle PB is continuously casing on the cardboard DB.

Here, soft bottles and the like are increasing as recent bottles. Therefore, when the bottle PB is transported on the bottle transport path L1, the container main body YO and the like are distorted due to vibration, impact, etc., and the small diameter portion HO of the bottle PB cannot be returned with a positional shift. May end up. For example, as shown in FIG. 15, the bottle PB1 is disposed at an appropriate position with respect to an appropriate center line PO in which the small diameter portion HO is not shifted in the horizontal direction / vertical direction. On the other hand, in the bottles PB2 and PB3, the small diameter portion HO is shifted from the center line PO and cannot be returned.
Since the grip portion 105 is arranged assuming that the small diameter portion HO is at an appropriate position on the center line PO like the bottle PB1, the positional deviation of the small diameter portion HO like the bottles PB2 and PB3. If this occurs, the grip portion 105 cannot properly grip the small-diameter portion HO, resulting in a grip failure.

The elevating belt unit 3 includes a driving unit (not shown) and a belt 3 a wound around a pair of support columns 2. A connecting portion 7 is connected to the belt 3a.

  Under such a configuration, the elevating belt unit 3 elevates and lowers the gripping device 10 through the connecting unit 7 by elevating operation, and winds the belt 3a in the short direction M by the driving unit of the elevating belt unit 3. Thus, the gripping device 10 is reciprocated in the short direction M via the connecting portion 7.

As shown in FIG. 2, the gripping device 10 includes a pair of gripping main body portions 11a and 11b.
The grip body parts 11a and 11b are formed in a rectangular plate shape, and are arranged in parallel so as to face each other in the vertical direction. The grip body parts 11a and 11b are slidable in the horizontal direction (conveying direction A and the opposite direction), and are urged toward each other by an urging member (not shown).
Grip portions 12a and 12b extending opposite to each other are provided at the lower ends of the grip body portions 11a and 11b. The grip portions 12a and 12b are extended in directions approaching each other in a direction perpendicular to the extending surfaces of the grip body portions 11a and 11b. In addition, notches 13a and 13b that are arcuately formed are formed at the tips of the gripping portions 12a and 12b. The arcs of the notches 13a and 13b are formed with the same curvature as the narrow diameter portion (gripping part) HO of the bottle PB.

Cylinders 17a and 17b adjacent to each other in the direction orthogonal to the conveyance direction A are provided between the upper ends of the grip main bodies 11a and 11b. The cylinders 17a and 17b are provided with shaft portions 19a and 19b that are alternately arranged and extend in the conveying direction A and in the opposite direction. Abutting plates 18a and 18b are provided at the tips of the shaft portions 19a and 19b. The shaft portions 19a and 19b are projected and retracted in the axial direction by, for example, oil pressure. The contact plates 18a and 18b come into contact with the inner surfaces of the upper end portions of the gripping main body portions 11a and 11b.
With such a configuration, when the cylinders 17a and 17b are turned on, the shaft portions 19a and 19b are projected from the cylinders 17a and 17b, so that the gripping main body portions 11a and 11b are moved through the contact plates 18a and 18b. The urging member moves in a direction away from each other against the urging force of the urging member. On the other hand, when the cylinders 17a and 17b are turned off, the shaft portions 19a and 19b are submerged in the cylinders 17a and 17b, so that the gripping main body portions 11a and 11b move in a direction approaching each other by the biasing force of the biasing member. It has become.

Further, among the inner surfaces of the gripping main body portions 11a and 11b, alignment portions (clamping portions) 15a and 15b arranged to face each other are provided in the center portion in the longitudinal direction.
The alignment portions 15a and 15b are extended from the inner surfaces of the grip main body portions 11a and 11b in a direction approaching each other. Concave portions 16a and 16b are formed at the tips of the alignment portions 15a and 15b. The recesses 16a and 16b are formed in a triangular shape in plan view, that is, both ends in the width direction protrude, and the center portions (deepest portions) 16a1 and 16b1 (shown in FIG. 6) are inwardly recessed. Therefore, inclined surfaces (guide surfaces) are formed in the recesses 16a and 16b from both ends in the width direction toward the center thereof.

Also, an upper surface pressing portion 20 is provided below the cylinders 17a and 17b and above the alignment portions 15a and 15b.
The upper surface pressing portion 20 is disposed above the central portion between the gripping portions 12a and 12b. Moreover, the upper surface pressing part 20 is formed in U shape, and the bottom face part is extended in the horizontal direction. Furthermore, the upper surface pressing portion 20 is provided so as to be movable in the vertical direction (vertical direction), and is urged downward in the vertical direction by an urging member (not shown).
Under such a configuration, the gripping portions 12a and 12b approach and separate from each other by turning on and off the cylinders 17a and 17b, whereby the concave portions 16a and 16b of the alignment portions 15a and 15b approach and separate from each other. .

Next, the operations of the inter-path transfer device 1 and the gripping device 10 in the present embodiment configured as described above will be described.
The gripping device 10 is arranged above the bottle transport path L1, and the gripping main body portions 11a and 11b are separated from each other when the cylinders 17a and 17b are turned on.
First, as shown in FIG. 3, the bottle PB is transported in the transport direction A on the bottle transport path L <b> 1 and is stopped at a position below the gripping device 10 in the adjacent portion F. At this time, the cap (near the gripping part) CA of the bottle PB is arranged in the center between the gripping parts 12a and 12b in plan view. That is, the centers of the cap CA, the small diameter portion HO, and the container main body portion YO are arranged on the center line PO. The center line PO refers to an imaginary line that passes through the center of the cap CA, the center of the small diameter portion HO, and the center of the bottom surface of the container body YO. The positions of the cap CA and the small diameter portion HO when the center of the cap CA, the center of the small diameter portion HO, and the center of the bottom surface of the container main body portion YO pass through the center line PO are referred to as appropriate positions.
Further, as shown in FIG. 4, the gripping device 10 moves downward. Thereby, the small diameter portion HO is arranged in the center between the gripping main body portions 11a and 11b in a side view. Then, the bottom surface of the upper surface pressing portion 20 comes into contact with the upper surface of the cap CA, and the gripping device 10 further moves downward. Therefore, the cap CA slightly sinks downward and the upper surface pressing portion 20 is pressed upward by the reaction of the cap CA. As a result, the upper surface pressing portion 20 moves upward relative to the gripping main body portions 11a and 11b against the urging force of the urging member (not shown), and the cap CA is further moved by the urging force of the urging member. Is pressed downward.
At this time, the alignment portions 15a and 15b face the outer peripheral surface of the cap CA, and the gripping portions 12a and 12b face the outer peripheral surface of the small-diameter portion HO.

  In this state, the cylinders 17a and 17b are turned off, and the gripping main body portions 11a and 11b move in a direction approaching each other as shown in FIG. Thereby, the notch parts 13a and 13b of the holding parts 12a and 12b contact the outer peripheral surface of the small diameter part HO. At this time, since the arcs of the cutout portions 13a and 13b and the curvature of the small diameter portion HO are the same, the cutout portions 13a and 13b contact the outer peripheral surface of the small diameter portion HO over the entire length thereof. As a result, the small diameter portion HO is gripped by the gripping portions 12a and 12b. When the cap CA and the small diameter portion HO are disposed at appropriate positions and the grip portions 12a and 12b are gripping the small diameter portion HO, the concave portions 16a and 16b of the alignment portions 15a and 15b are provided. Is set so as not to contact the outer peripheral surface of the cap CA.

  Next, in a state where the gripping portions 12a and 12b grip the small-diameter portion HO, the gripping device 10 moves upward and further moves horizontally above the corrugated board conveyance path L2. As shown in FIG. 1, an empty cardboard DB is disposed in the adjacent portion F on the cardboard conveyance path L2. Therefore, the bottle PB is accommodated in the cardboard DB by moving the gripping device 10 downward. When the cylinders 17a and 17b are turned on, the grip main bodies 11a and 11b are separated from each other, and the bottle PB is released in the cardboard DB. Further, the gripping device 10 is returned to the bottle conveyance path L1, and the cardboard DB in a state where the bottle PB is accommodated is conveyed in the conveyance direction B on the cardboard conveyance path L2.

Here, as shown in FIG. 6, when the center point P1 of the cap CA and the small diameter portion HO is shifted from the center line PO, the grip portions 12a and 12b may not properly hold the small diameter portion HO. is there. In FIG. 6, the symbol G indicates an appropriate position (gripping position) in the horizontal direction. 6 to 8, only the alignment portions 15a and 15b and the cap CA are shown for convenience of explanation.
According to the gripping device 10 and the inter-road conveyance device 1 in the present embodiment, the cap CA and the small diameter portion HO are aligned with the appropriate position G as follows.
While the center point P1 of the cap CA and the small-diameter portion HO is shifted from the center line PO, the alignment portions 15a and 15b move in a direction in which they approach each other. As shown in FIG. 7, the inclined surfaces of the recesses 16a and 16b abut against the outer peripheral surface of the cap CA. Since the recesses 16a and 16b are formed so as to be sunk with respect to the appropriate position G, when the alignment portions 15a and 15b move in the same direction, the cap CA and the small diameter portion HO are moved to the recesses 16a and 16b. It is guided by the inclined surface and moves toward the appropriate position G. Here, the center portions 16a1 and 16b1 of the recesses 16a and 16b are provided to face the center line PO, in other words, at the center on the virtual line J connecting the center portions 16a1 and 16b1 in plan view. The center line PO is arranged. Therefore, as shown in FIG. 8, when the cap CA and the small diameter portion HO move to the central portions 16a1 and 16b1, the center point P1 is arranged on the center line PO, and the cap CA and the small diameter portion HO are in the proper positions. Arranged in G.

Further, the cap CA and the small-diameter portion HO are not only displaced on the horizontal plane, but may also be displaced in the vertical direction as shown in FIG. Even in that case, the positional deviation between the cap CA and the small diameter portion HO is eliminated as follows. 9 to 10, only the upper surface pressing portion 20 of the gripping device 10 is shown for convenience of explanation.
In a state where the cap CA and the small diameter portion HO are displaced in the vertical direction, the upper surface pressing portion 20 moves downward. And the upper surface pressing part 20 contacts from the highest point of the cap CA, and further presses the cap CA downward. Accordingly, as shown in FIG. 10, the cap CA moves slightly downward together with the small diameter portion HO, and is disposed at the proper position G in the vertical direction. That is, regardless of whether the cap CA and the small diameter portion HO are displaced in the vertical direction, the upper surface pressing portion 20 presses the cap CA, so that the cap CA and the small diameter portion HO are slightly lower than those at the time of conveyance. Will be placed in the position. This position is an appropriate position G in the vertical direction.

As described above, according to the inter-road conveyance device 1 and the gripping device 10 in the present embodiment, even if the cap CA and the small diameter portion HO are deviated from the appropriate position G, the cap CA and the thin portion are aligned by the alignment portions 15a and 15b. The diameter portion HO can be guided toward the appropriate position G. Therefore, the narrow-diameter portion HO of the bottle PB that is continuously conveyed can be disposed facing the grip portions 12a and 12b, and the bottle PB can be gripped appropriately.
Further, since the concave portions 16a and 16b are formed in the grip portions 12a and 12b, the cap CA and the small diameter portion HO can be guided to the appropriate position G, and the cap CA and the small diameter portion HO can be guided to the proper position G. It can be moved easily.
Further, since the concave portions 16a and 16b are formed in a triangular shape, the cap CA and the small diameter portion HO can be gently guided to the appropriate position G, and the cap CA and the small diameter portion HO can be surely reached to the proper position G. Can be moved to.
Further, since the triangular shape of the recesses 16a and 16b is formed from both ends in the width direction of the alignment portions 15a and 15b toward the center thereof, the cap CA is provided from both ends of the recesses 16a and 16b toward the center thereof. You can guide smoothly.

Further, since the concave portions 16a and 16b are formed in both the grip portions 12a and 12b, the cap CA and the small diameter portion HO can be reliably moved to the appropriate position G while sandwiching the cap CA.
Further, since the inclined surfaces of the recesses 16a and 16b are configured not to contact the outer peripheral surface of the cap CA disposed at the appropriate position G, the load applied to the outer peripheral surface of the cap CA can be reduced. . That is, the inclined surfaces of the recesses 16a and 16b and the outer peripheral surface of the cap CA are not easily caught, so that the cap CA and the small diameter portion HO can be smoothly moved to the appropriate position G. Furthermore, the bottle PB can be reliably gripped without obstructing the gripping of the small-diameter portion HO by the gripping portions 12a and 12b.
In addition, since the vibration and impact at the time of conveyance applied to the bottle PB often occur in the conveyance direction A and the opposite direction, the displacement of the cap CA and the small diameter portion HO is larger in the conveyance direction A and the opposite direction. It tends to occur. In the present embodiment, the alignment portions 15a and 15b slide so as to approach each other from the transport direction A and the opposite direction, so that a larger positional shift between the cap CA and the small diameter portion HO is corrected. Can do.
Further, since the cap CA is pressed downward by the upper surface pressing portion 20, the vertical displacement between the cap CA and the small diameter portion HO can also be corrected.

The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, although the recesses 16a and 16b are formed in both of the alignment portions 15a and 15b, the present invention is not limited to this, and as shown in FIG. 11, a pair of alignment portions 15a and 15a, It may be 15c. That is, the concave portion 16a may be formed only in the alignment portion 15a, and the opposing alignment portion 15c may have a flat shape extending linearly in the width direction of the alignment portion 15c. Thereby, as shown in FIG. 12, the larger gap | deviation of the cap CA and the small diameter part HO can be corrected. More specifically, when the recesses 16a and 16b are formed in any of the paired alignment portions 15a and 15b, it is possible to dispose the cap CA1 in the vicinity of the appropriate position G between the alignment portions 15a and 15b. Although it can, cap CA2 etc. cannot be arranged in the part which the both ends of crevice 16a and 16b projected.
However, by making only one alignment portion 15c flat, it is possible to eliminate the protruding portions at both ends of the recess 16b, and to correct the positional deviation of the cap CA2. At this time, the cap CA2 can be guided to the appropriate position G by the concave portion 16a and the facing surface of the alignment portion 15c.

In the present embodiment, the alignment units 15a and 15b are paired. However, the present invention is not limited to this, and the number thereof may be any number.
Further, the cap CA is guided to the appropriate position G by being sandwiched between the alignment portions 15a and 15b, but the configuration is not limited to this, and the configuration can be changed as appropriate. For example, a ring member having a taper whose diameter increases downward may be placed on the cap CA from above. That is, the cap CA can be moved to the appropriate position G by being guided by the taper. At this time, since the taper can not only move the cap CA in the horizontal direction but also in the vertical direction, it is not necessary to provide the upper surface pressing portion 20 as a separate member.
Further, although the bottle PB is a gallon bottle made of soft PET, the present invention is not limited to this, and the object to be conveyed can be changed as appropriate. For example, a bag-in-box before being inserted into the box may be used.

In addition, the angle θ of the central portions 16a1 and 16b1 of the recesses 16a and 16b shown in FIG. 6 can be changed as appropriate. For example, the angle θ can be set to 80 ° or more and 120 ° or less. In particular, the angle θ is preferably 90 ° or more and 120 ° or less.
If the angle θ is set to less than 80 °, the required depth dimensions of the recesses 16a and 16b become too large, and the alignment portions 15a and 15b are enlarged. On the other hand, if the angle θ is set to more than 120 °, the inclination angle of the inclined surface becomes too small, so that it is difficult to slide the cap CA and move the cap CA outside the proper position G. Prone.
In addition, the upper surface of the cap CA is pressed downward by the upper surface pressing portion 20, and then the cap CA is sandwiched by the alignment portions 15a and 15b (15c). However, the order may be reversed or simultaneously. There may be. For example, even if the cap CA is sandwiched by the alignment portions 15a and 15b (15c) and the cap CA is moved to the appropriate position G in the horizontal direction, the upper surface pressing portion 20 may press the upper surface of the cap CA downward. Good.
