Description

  The present invention relates to a container transport device including a double-row conveyor that doubles containers that are transported in a single row.

  2. Description of the Related Art Conventionally, as such a container transport device, a device provided with an accumulator that transports a container transported in a single row in a double row and transports it at a slower speed is known (for example, see Patent Document 1). In this container transport device, containers transported in a single row by a single-row conveyor are dispersed by an accumulator conveyor to form a double row.

  The accumulator conveys the entrance conveyor driven at half the speed of the single-line conveyor, the capacity adjustment conveyor driven at an eighth of the entrance conveyor, and the transport speed six times that of the capacity adjustment conveyor. And an accumulator main body conveyor driven by the motor. In this case, the accumulator main body conveyor is driven at a transport speed of 3/8 that of the single row conveyor.

  The containers conveyed by the single-line conveyor are conveyed while being dispersed by receiving a light pressing force between the containers on the entrance conveyor. The dispersed containers are conveyed while accumulating while being further dispersed under the restriction of the slow capacity adjusting conveyor.

  And the collected container is conveyed in the state isolate | separated for every row | line | column by the accumulator main body conveyor whose conveyance speed is quicker than a capability adjustment conveyor. In this way, the containers sent out from the single-row conveyor are dispersed and double-rowed, and are transported at a slower transport speed by the accumulator main body conveyor.

  On the other hand, a method of using a robot hand without using an accumulator is also known as a method of making a row of containers conveyed in a single row. In this case, double rows are formed by repeating the operation of lifting a predetermined number of containers conveyed by a single row conveyor by a robot hand and placing them in a double row state on the double row conveyor.

JP 2009-234763 A

  In recent years, the weight of containers has been increasing. For example, in the case of a 500 [ml] plastic bottle, an ultra-light weight of 12 [g] or less and a light carbonate bottle of 24 [g] or less have been used. Accordingly, there is a need for a container transport apparatus that can perform stable transport at high speed without causing a reduction in operating rate due to a fall or a decrease in quality due to an impact on a container that has been reduced in weight.

  However, according to the container transport device of Patent Document 1, when the containers are double-rowed, the accumulator is dispersed and accumulated while being pushed between the guides on both sides of the transport path by the pressing force between the containers. . For this reason, there is no problem as long as the container is high in strength, but in the case of a container that has been reduced in weight, the pressing force between the containers may cause dents and damage, which may reduce the quality.

  On the other hand, according to the method of performing double row using the robot hand described above, in the case of a container that has been reduced in weight, there is a possibility that a dent or damage may occur when gripped by the robot hand. In addition, there is a high probability that the container will fall over when the container is gripped or placed. Moreover, the cost of a container conveying apparatus becomes high.

  An object of the present invention is to provide a container transport device that can perform double-row arrangement of containers with a simple configuration without causing deterioration in the quality of the container or overturning.

  The container transport device of the present invention includes a single-row conveyor that transports containers in a single row, and a double-row conveyor that is provided in parallel with the single-row conveyor and transports the containers in a double row and at a lower speed than the single-row conveyor. And a plurality of unit conveyors provided in parallel with the single row conveyor and the double row conveyor and between the downstream end of the single row conveyor and the upstream end of the double row conveyor. A plurality of unit conveyors are adjacent to the single row conveyor, and are connected to the starting end unit conveyor that conveys the containers at a speed lower than or equal to that of the single row conveyor, and the double row conveyor. And at least a terminal unit conveyor that conveys the container at a speed higher than or equal to that of the double-row conveyor, and the conveying speed of the plurality of unit conveyors is determined from the starting unit conveyor. It is set so as to slow down in order toward the end unit conveyor, the conveyance surface of the downstream end of the single row conveyor, the conveyance surface of the double row conveyor, and the conveyance surface of the upstream end of the double row conveyor are: The inclined surface is inclined so as to become lower from the downstream end to the upstream end.

  In the configuration of the present invention, when the container conveyed by the single-line conveyor reaches the downstream end of the single-line conveyor, the container is conveyed in the conveying direction, and the downstream end forms the uppermost portion. Start sliding down along the surface in an inclined direction. The containers that have started to slide down move onto the double-row conveyor, and the speed in the unit conveyor direction decreases while moving on each of the unit conveyors where the sequential transfer speed of the double-row conveyor becomes slower.

  Therefore, each container sequentially sent out from the single-line conveyor sequentially catches up with the preceding container or is caught up with the container behind the container, and comes into contact with the preceding and following containers. At this time, the containers are dispersed because they are pressed against each other. However, the reaction force generated between the containers at that time is caused by the difference in speed, so that the container is not damaged or falls.

  Further, each container is fluid because it slides down on the inclined surface. This facilitates container dispersion. That is, the frictional force acting between the inclined surface and each container is slightly different for each container. Such a difference in frictional force promotes the dispersion of the containers sliding down the inclined surface, particularly in the inclined direction.

  Each container is distributed on the inclined surface by the action of the double row conveyor and the inclined surface. Each container is in a double row state when reaching the upstream end of the double row conveyor, and is transferred to the double row conveyor in this state. Therefore, according to the present invention, it is possible to achieve double rows of containers with a simple configuration without causing deterioration in the quality or overturning of the containers.

  In the present invention, the shape of the inclined surface in the inclined surface may be a shape in which the inclination angle gradually decreases toward the upstream end of the double-line conveyor and becomes horizontal at the upstream end.

  According to this, the kinetic energy in the inclined direction imparted to the container by sliding down on the inclined surface is caused by the frictional force between the container and the inclined surface as the container approaches the upstream end of the double row conveyor. It is gradually lost. In the meantime, in a plurality of containers, the degree that the difference in frictional force between the containers and the inclined surface appears as a difference in position in the inclination direction between the containers increases. Therefore, it is possible to smoothly deliver the double-rowed containers to the double-row conveyor while effectively promoting the dispersion of the containers in the tilt direction.

  In the present invention, in the inclined surface, the kinetic energy in the inclination direction of the container descending the inclined surface becomes zero on the upstream end of the double row conveyor due to friction between the container and the inclined surface. It may be formed as follows.

  According to this, since the kinetic energy in the inclination direction of the containers becomes substantially zero on the upstream end of the double-row conveyor, the double-row movement of the containers is reliably ensured while promoting the dispersion state of the containers. It can be stopped on the upstream end of the conveyor. Thereby, the container which carried out the favorable dispersion | distribution and doubled can be reliably delivered to a double-row conveyor.

  In the present invention, the inclined surface includes an upper end side of the inclined surface, and a portion that increases the kinetic energy of the container and a portion that decreases the kinetic energy below this to zero. The friction coefficient x between the inclined surface and the container and the inclination angle y of the upper end portion of the inclined surface may satisfy y = 3.2724x + b for b in the range of 5.4862 ± 0.4.

  According to this, by forming the inclined surface as having a friction coefficient x with the container satisfying the above relational expression and the inclination angle y of the upper end portion of the inclined surface, it is possible to easily achieve double row of containers. Can do. Further, by selecting a value as close as possible to 5.4862 as the value of the y-intercept b, it is possible to achieve double-rowing in a state of being properly distributed around the center of the double-row conveyor.

It is a top view which shows the principal part of the container conveying apparatus which concerns on one Embodiment of this invention. It is a figure which shows the shape of the inclination direction of the inclined surface in the container conveying apparatus of FIG. It is a figure which shows the state of the row | line | column of the container in a double-row conveyor at the time of changing the inclination | tilt angle (alpha) of the upper end part of an inclined surface about 3 types of containers by the container conveying apparatus of FIG. FIG. 4 is a graph showing the relationship between the friction coefficient of each container and the inclination angle α when the results of “left side ○”, “center ◎”, and “right side ○” in FIG. 3 are obtained. The axis is the inclination angle α (°).

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. As shown in FIG. 1, the container transport device 1 according to the embodiment includes a single-line conveyor 3 that transports the standing containers 2 in a single row and at a high speed, and is provided in parallel to the single-row conveyor 3. A double-row conveyor 4 that transports at a lower speed than the single-row conveyor 3 and a double-row conveyor 5 that couples the single-row conveyor 3 and the double-row conveyor 4 are provided.

  Examples of the container 2 include an ultralight bottle having a capacity of 500 [ml] and a weight of 12 [g] or less, and a light carbonate bottle having a capacity of 500 [ml] and a weight of 24 [g] or less. . The single row conveyor 3 is configured by connecting a required number of conveyor chains 6 as unit conveyors in the length direction. The conveyor chain 6 is made of resin and is driven by a motor.

  The double-row conveyor 4 is configured by arranging a plurality of conveyor chains 6 driven at the same conveyance speed in parallel in the horizontal direction. Here, the double-row conveyor 4 is constituted by five conveyor chains 6. The double row conveyor 4 conveys the double-rowed containers 2 at a slower speed than the single row conveyor 3.

  The double-row conveyor 5 is composed of a plurality of conveyor chains 6 provided in parallel with these conveyors between the downstream end 3a of the single-row conveyor 3 and the upstream end 4a of the double-row conveyor 4. The These conveyor chains 6 are sequentially slower from the first conveyor chain 6 as the starting end unit conveyor adjacent to the single row conveyor 3 to the last conveyor chain 6 as the end unit conveyor adjacent to the double row conveyor 4. Driven at the conveyance speed.

  The first conveyor chain 6 is driven at a conveyance speed slower than that of the single-line conveyor 3 or a conveyance speed equivalent to that of the single-line conveyor 3. The last conveyor chain 6 is driven at a conveyance speed faster than the double-row conveyor 4 or a conveyance speed equivalent to that of the double-row conveyor 4. In addition, the conveyance speed of each conveyor chain 6 is shown by the horizontal arrow (vector) on each conveyor chain 6 in FIG.

  The conveyance path of the containers 2 from the single-line conveyor 3 through the double-line conveyor 5 to the double-line conveyor 4 is defined by a container guide 7 that guides the containers 2 along the conveyance path. Of the container guide 7, an S-shaped portion provided from the downstream side of the downstream side end portion 3 a of the single-line conveyor 3 to the downstream side of the double-lined conveyor 5 constitutes the dispersion promotion guide 7 a.

  The dispersion promotion guide 7a crosses each conveyor chain 6 of the single-row conveyor 3 and the double-row conveyor 5 and hits the container 2 being conveyed, so that the upstream end of the double-row conveyor 4 with respect to the container 2 Apply kinetic energy in the direction toward 4a.

  The shape and size of the dispersion promoting guide 7a in the length direction and the conveying speed of each conveyor chain 6 of the double-row conveyor 5 are devised so that the container 2 hitting the dispersion promoting guide 7a is not damaged or falls. Yes.

  The downstream end 3a of the single-row conveyor 3, the double-row conveyor 5 and the upstream-side end 4a of the double-row conveyor 4 transfer the containers 2 that are sequentially conveyed to the downstream edge 3a into the double-row conveyor. 5, the inclined surface 8 which is dispersed and doubled to be transferred to the upstream end 4a is formed.

  The inclined surface 8 jacks up the single-line conveyor 3 side of the laterally extending beams that commonly support the single-line conveyor 3, the double-line conveyor 5, and the conveyor chain 6 constituting the double-line conveyor 4, for example. Is formed. Therefore, in reality, the inclined surface 8 is formed by, for example, inclining the entire conveyor chain 6 included in the region surrounded by the one-dot chain line in FIG. Is formed.

  As shown in FIG. 2, the shape of the inclined surface 8 in the inclination direction S, that is, the shape of the cross section orthogonal to the conveyor chain 6, gradually decreases the inclination angle toward the upstream end 4 a of the double-row conveyor 4, It is a shape that moves to.

  That is, the inclined surface 8 includes a main portion 8a on the upper end side where the inclination angle gradually decreases and a horizontal portion 8b on the lower lower end side. The inclination angle α with respect to the horizontal plane 9 at the upper end of the main portion 8a is, for example, about 6 to 7 [°].

  The coefficient of friction between the inclined surface 8 and the container 2 is substantially constant. The shape and dimensions of the inclined surface 8 are such that the kinetic energy in the inclination direction S of the container 2 increases in the main part 8a, decreases in the vicinity of the horizontal part 8b and in the horizontal part 8b, and reaches zero in the horizontal part 8b. Determined.

  In this configuration, when the container 2 conveyed by the single-line conveyor 3 reaches the downstream end 3a of the single-line conveyor 3, it starts to descend by gravity along the inclined surface 8 that it constitutes. At this time, the container 2 hits the dispersion promotion guide 7a and is additionally given kinetic energy in the direction of inclination of the inclined surface 8.

  The container 2 that has started descending passes through the double-row conveyor 5 and reaches the upstream end 4 a of the double-row conveyor 4. During this time, as the container 2 moves on each conveyor chain 6 of the double-row conveyor 5, the speed in the transport direction decreases in accordance with the transport speed at which each conveyor chain 6 sequentially decreases.

  Therefore, each container 2 sent out from the single-line conveyor 3 continuously catches up with the container 2 in front of it or is caught up with the container 2 behind it, and comes into contact with the containers 2 in front and behind and presses against each other.

  However, the reaction force generated between the containers 2 in contact with each other is generated with a slight speed difference while traveling on substantially the same path. Further, when the containers 2 are pressed against each other, the position of the container 2 is easily shifted along the inclined surface 8. For this reason, the reaction force does not cause an impact that causes damage or overturn to the container 2.

  Further, the frictional force of each container 2 against the inclined surface 8 is slightly different for each container 2. For this reason, the speed at which the container 2 descends the inclined surface 8 in the inclination direction S is slightly different for each container 2. Due to the contact between the containers 2 and the speed difference between the containers 2, each container 2 is dispersed in the process of traveling on the inclined surface 8, as shown in FIG.

  That is, the container group including the containers 2 sent out from the single-line conveyor 3 at a high speed is given pressure from the upstream side by being decelerated by the double-line conveyor 5. The inclined surface 8 promotes that the container group expands in the lateral direction by the pressure. As a result, the flow of the container group proceeds toward the upstream end 4a of the double-row conveyor 4 while slowing and thickening.

  During this time, since the inclination angle of the inclined surface 8 gradually decreases as shown in FIG. 2, the kinetic energy imparted to the container 2 by descending on the inclined surface 8 is the upstream end of the double-row conveyor 4. As it approaches the part 4a, it is gradually lost by the frictional force between the container 2 and the inclined surface 8. The container 2 is inclined while the kinetic energy in the inclination direction becomes substantially zero on the substantially horizontal conveying surface at the upstream end 4a, and the dispersed state of the container 2 promoted on the inclined surface 8 is maintained. Directional movement stops.

  At that time, the stopping position of the container 2 is greatly affected by the frictional force between the container 2 and the conveying surface of the upstream end 4a. Dispersion in the tilt direction is promoted. At this time, the container guide 7 along the double-row conveyor 4 regulates the dispersion of the containers 2 exceeding the width of the double-row conveyor 4, so that the width of the container group is aligned with the width of the double-row conveyor 4. .

  However, the width of the container group at this time is reasonably widened by the cooperation of the double-row conveyor 5 and the inclined surface 8. At this time, a large pressing force from the rear is not applied to the container group. For this reason, the contact between the container guide 7 and the container 2 when the width of the container group is regulated by the container guide 7 is not so large as to cause the quality of the container 2 to deteriorate or to fall.

  In this way, each container 2 that decelerates and disperses while traveling on the inclined surface 8 is in a double-row state when it reaches the upstream end 4a of the double-row conveyor 4 and becomes a double-row conveyor 4. Is passed on. Thereby, the smooth double row | line | column formation of the container 2 is achieved by simple structure, without causing the quality fall of the container 2 or a fall.

  FIG. 3 shows the three types of bottles A to C shown in the “container” column of the table, which have a dynamic friction coefficient with the conveyor chain 6 shown in the “friction coefficient” column. Shows the result of trying to make a double row. An attempt is made to make a double row by setting the inclination angle α of the upper end portion of the main portion 8a of the inclined surface 8 shown in FIG. 2 to seven values shown in the “inclination angle α” column.

  However, this trial is performed under the following conditions. That is, in the inclined surface 8 in the inclination direction S shown in FIG. 2, the length of the main portion 8a is 671 [mm], and the length of the horizontal portion 8b is 430 [mm]. Further, the bottles A to C are all different in weight. The container 2 descends on the inclined surface 8 without colliding with the dispersion promoting guide 7a.

  In the table in FIG. 3, “center ◎” in the “inclination angle α” column indicates that the containers 2 are double-rowed in a state of being properly distributed around the center of the double-row conveyor 4 in the transport direction. Indicates. “Right-side ◯” means that the containers 2 are double-rowed in a state of being shifted to the right side (double-row conveyor 5 side) with respect to the transport direction. “Left-side o” means that the containers 2 are doubled in a state of being shifted to the left side with respect to the transport direction. “X” means that the container 2 was not properly dispersed and the container 2 was congested and could not be doubled.

  As shown in FIG. 3, when the double-row is performed using the bottle A having a friction coefficient of 0.13 as the container 2, when the inclination angle α is 5.5 [°], the “left side ○” It was “center” at 5.9 [°], “right side o” at 6.3 [°], and “x” at 5.1 [°] and 6.7.

  Further, in the case of bottle B having a friction coefficient of 0.36, when the inclination angle α is 6.3 [°], “left side ○”, and when 6.7 [°], “center ◎”, 7.1 [°] In the case of “right side ○”, in the case of 5.9 [°] and 7.5, it was “x” that could not be double-rowed.

  In the case of bottle C having a friction coefficient of 0.47, “left side ○” when the tilt angle α is 6.7 [°], “center ◎” when 7.5 [°], 7.5 [°] In the case of “right side ○”, and in the case of 6.3 [°] and 7.9 [°], it was “x” incapable of double row.

  From these results, when the friction coefficient of the container 2 is small, the inclination angle α is decreased, and when the friction coefficient is large, the inclination angle α is increased so that the container 2 is centered on the center of the double-row conveyor 4. It can be seen that an appropriate distributed double row is performed.

  4 approximates the relationship between the coefficient of friction and the inclination angle α with straight lines L, C, and R when the results of “left side ○”, “center ◎”, and “right side ○” in FIG. 3 are obtained. Results are shown. As shown in FIG. 4, the relationship between the coefficient of friction of the container 2 and the inclination angle α of the inclined surface 8 when the results of “left side ○”, “center ◎”, and “right side ○” are obtained are straight lines L, C , R can be approximated well and has a substantially linear relationship.

For example, in the case where the result of “center ◎” is obtained, if the friction coefficient is x, the inclination angle α is y, and approximated by the straight line C, the equation of the straight line C is y = 3.2724x + 5.4862. Is obtained. The value of the coefficient of determination R 2 is 0.9969, and very well approximated.

  The straight lines L and R are translated from the straight line C in the y direction by −0.4 and +0.4, respectively. Therefore, the graph of FIG. 4 employs a combination corresponding to the coordinate point between the straight line R and the straight line L of the graph of FIG. By forming, it means that a double row of “left side ○”, “center ◎” or “right side ○” can be achieved.

  That is, if the relational expression between the friction coefficient x and the value y of the inclination angle α is expressed by y = 3.2724x + b, this relational expression is satisfied for the y intercept b of any value in the range of 5.486 ± 0.4. The coefficient of friction x and the value y of the inclination angle α may be adopted. However, as the value of the y-intercept b is closer to 5.4862, it is possible to form a double row in a state of being more appropriately distributed around the center of the double row conveyor 4.

  The dimensions and shapes of the main portion 8a and the horizontal portion 8b shown in FIG. 2 are average values that can be applied when double rows are used in normal bottle transport. Therefore, by forming the inclined surface 8 using the above-mentioned relational expression y = 3.2724x + b and the range 5.4862 ± 0.4 that the y-intercept b can take, the double-row arrangement of the containers 2 is almost achieved. It is considered possible.

  In addition, the result of FIG. 3 shows that the inclination angle α and the shape and dimensions of the inclined surface 8 can be determined based on the friction coefficient of the container 2 regardless of the weight of the container 2. means. That is, the kinetic energy obtained by the container 2 when it descends against the frictional force on the inclined surface 8 decreases with the frictional force as it approaches the double-row conveyor 4, and averages zero near the center of the double-row conveyor 4. Thus, it is considered that a good double row can be achieved by determining the shape and dimensions of the inclined surface 8.

  As described above, according to the present embodiment, the containers 2 can be dispersed to form a double row by the cooperation of the double row conveyor 5 and the inclined surface 8, and can be delivered to the upstream end 4a. Therefore, it is possible to achieve double rows of the containers 2 with a simple configuration without causing deterioration of the quality of the containers 2 or overturning.

  In addition, the inclined surface 8 has a shape in which the inclination direction becomes horizontal with the inclination angle gradually decreasing toward the upstream end portion 4 a of the double-row conveyor 4. For this reason, as the container 2 approaches the upstream end 4a, the difference in frictional force between the inclined surfaces 8 between the containers 2 increases the difference in the position in the inclined direction between the containers 2, so that the container 2 moves in the inclined direction. Can be effectively promoted.

  Further, the inclined surface 8 sets the kinetic energy in the inclination direction of the container 2 descending the inclined surface 8 to zero on average when the container 2 reaches the center of the upstream end 4a of the double-row conveyor 4. Has shape and dimensions. Thereby, the dispersion | distribution of the container 2 is accelerated | stimulated, and the movement to the inclination direction of the container 2 can be stopped reliably on the upstream edge part 4a, and appropriate double row | line | column can be achieved.

  Further, the shape and size of the inclined surface 8 are determined based on the friction coefficient of the container 2 with respect to the inclined surface 8. According to this, the shape and dimension of the inclined surface 8 that is inclined so that each container 2 is dispersed and transferred to the upstream side end of the double-row conveyor 5 in a double row can be easily obtained by calculation. be able to.

  Further, since the kinetic energy in the inclined direction of the inclined surface 8 can be additionally applied to the container 2 by the dispersion promotion guide 7a, the dispersion of the container 2 can be promoted and the double row can be quickly performed. it can. Thereby, the compaction of the double row conveyor 5 can be achieved.

  In addition, by configuring the inclined surface 8 to have the friction coefficient x satisfying the relational expression y = 3.2724x + b and the value y of the inclination angle α, it is possible to easily achieve double rows of the containers 2. Further, by selecting a value as close as possible to 5.4862 as the value of the y-intercept b, it is possible to achieve double-rowing in a state of being properly distributed around the center of the double-row conveyor 4.

  Although the embodiment has been described above, the present invention is not limited to this. For example, the dispersion promotion guide 7a may be omitted. That is, the container guide 7 does not necessarily have to hit the container 2 when the container 2 starts to descend on the inclined surface 8. In this case, the container 2 descends along the inclined surface 8 while increasing the kinetic energy only by its own weight.

    A double row composed of a plurality of unit conveyors provided in parallel with the single row conveyor and the double row conveyor and between the downstream end of the single row conveyor and the upstream end of the double row conveyor. And a conveyor
    The plurality of unit conveyors are adjacent to the single row conveyor, and are adjacent to the starting end unit conveyor that conveys the containers at a speed lower than or equal to that of the single row conveyor, the double row conveyor, and from the double row conveyor. Including at least a terminal unit conveyor that conveys the container at a high speed or an equivalent speed,
    The transport speed of the plurality of unit conveyors is set so as to decrease in order from the starting unit conveyor to the terminal unit conveyor,
    The conveyance surface of the downstream end of the single-line conveyor, the conveyance surface of the double-line conveyor, and the conveyance surface of the upstream-side end of the double-line conveyor are low from the downstream end to the upstream end. It is an inclined surface that is inclined so that
    The inclined surface is formed of a portion that forms the upper end side of the inclined surface and increases the kinetic energy of the container, and a portion that decreases the kinetic energy below this to zero,
    The coefficient of friction x between the inclined surface and the container and the inclination angle y of the upper end of the inclined surface satisfy y = 3.2724x + b for b in the range of 5.4862 ± 0.4. Container transport device.
