  The present invention relates to a conveyance control method and apparatus for an accumulator that aligns and accumulates bottles in front of a case packer in a conveyor line that conveys containers such as bottles (hereinafter referred to as bottles).

  In a packaging device such as a case packer, the bottle (bottle) supplied from the previous process is sorted and aligned by a sorting device, and then delivered to an orthogonal conveyor (bottle storage unit) by a pusher device for accumulating bottles. Has been proposed. (Patent Document 1)

Japanese Examined Patent Publication No. 6-84211 (FIGS. 1 and 6)

According to Patent Document 1, since the bottle is intermittently transferred from the bottle supply and alignment unit to the accumulation conveyor by the pusher device, the bottle conveyance capacity is limited, the accumulation efficiency is low, and it is suitable for high capacity. There is no problem.
In addition, in the accumulator conveyor, it is proposed that when a predetermined number of rows of bottles are fed, the bottles are transported at a high speed and collected at a stretch to the stopper at the end of the accumulator conveyor to shorten the accumulation time. In such a system, bottles collide strongly due to high-speed conveyance, or the bottle collides strongly with the stopper, so in particular when the bottle is filled with liquid, the label is affixed to the dent, scratch, or attached to the bottle by the impact force. There is a risk that scratches will occur.

  The purpose of the present invention is to prevent the bottles from being dented and scratched when the rear bottle comes into close contact with the front bottle on the conveyor in a conveyor line that aligns and accumulates the bottles in front of a case packer or the like. An object of the present invention is to provide a transfer control method and apparatus for a high-capacity accumulator that has high accumulation efficiency and that does not cause damage due to bottle pressure in downstream apparatuses.

Conveying speed increase accumulator part and downstream of the speed increasing accumulator part, the speed reducing accumulator part is transported so that it is fed to the conveyor of the subsequent process in a state of close contact The speed increasing accumulator section or the speed reducing accumulator section is further divided into a plurality of stages. The control unit calculates the amount of bottles on the conveyor based on the signal from the encoder provided on each divided conveyor, and detects whether the amount of bottles on the conveyor is full. A full detection sensor function is provided so that operation control such as stoppage of the conveyor, steady conveyance, and decelerating conveyance can be performed by a command from the control device.

(12) The transfer control method for the accumulator conveyor of the twelfth means is the same as the transport control method for the accumulator conveyor of the eleventh means, but is loaded on the most downstream conveyor of the acceleration accumulator section or the deceleration accumulator section. Stop the most downstream conveyor when the loading amount is full, and then stop the upstream conveyor when the bottle loading amount is full on the upstream conveyor immediately before the most downstream stage. As described above, when the amount of bottles placed on the conveyor reaches the full level from the most downstream stage to the upstream stage, the conveyor is stopped and accumulated.

(13) The transfer control method for the accumulator conveyor of the thirteenth means is the same as the transfer control method for the accumulator conveyor of the eleventh means, in which the bottles are placed on the conveyors of the acceleration accumulator section or the deceleration accumulator section. The amount is calculated by the encoder and the control device based on the distance traveled by the bottle from the head of the conveyor and the conveying speed of the conveyor.

(14) The conveyance control method for the accumulator of the fourteenth means is the conveyance control method for the accumulator conveyor of the eleventh to thirteenth means, wherein the conveyance speed of the conveyor of the acceleration accumulator section or the deceleration accumulator section is the same. When the conveyor is brought into a state corresponding to fullness by the fullness detection sensor function, the bottle is brought into close-conveyance order from the top in the conveyor. Accumulation control is performed so that the bottles stopped on the conveyor downstream of the conveyor are brought into close contact with each other so as not to give an impact.

Control is performed so that the bottles to be transported are brought into close contact with each other at least at the most downstream stage of the speed reduction conveyor portion.

  The present invention according to claim 2 has the effect that the amount of accumulation can be changed by changing the gap before and after the bottle conveyed by the speed increasing accumulator section according to the speed increasing ratio.

According to the third aspect of the present invention, since the decelerating accumulator unit is further disposed downstream of the speed increasing accumulator unit, the conveyance control is performed. In addition, it is possible to improve the accumulating efficiency by controlling the conveyance so that the rows are arranged in close contact with each other and are arranged in close contact with each other evenly.

In the first aspect of the present invention, at each stage of the conveyors arranged in series with the speed-increasing accumulator unit , the control device calculates the amount of bottles placed on the conveyor by a signal from an encoder provided on the conveyor. Therefore, it is possible to provide a function of a full detection sensor that detects whether or not the amount of bottles placed on the conveyor is equivalent to full. There is an effect that operation control such as conveyance can be efficiently performed.

  FIG. 2 to FIG. 6 are diagrams for explaining the accumulation state of the bottles transported and accumulated in the conveyor line as a change from FIG. 1, and FIG. 2 shows that the most downstream conveyor is full in the deceleration accumulator section. FIG. 3 is a diagram showing a state immediately before the deceleration accumulator portion is full, FIG. 4 is a state where the deceleration accumulator portion is full, and the most downstream portion of the acceleration accumulator portion is almost full. FIG. 5 shows a state where there is room for accumulation in the upstream portion, FIG. 5 shows a state where there is less room for accumulation in the acceleration accumulator portion than in FIG. 4, and FIG. 6 shows that the downstream portion of the deceleration conveyor portion is full. It is a figure which shows the case where it becomes and becomes a line stop state. In FIGS. 2 to 6, since the symbols of the apparatus are the same as those of FIG. 1, the conveyor symbols of each stage are displayed, but the display is omitted thereafter. FIG. 7 is an explanatory diagram of a part of the conveyor configuration.

  In the figure, bottles (containers) 1 are conveyed by a narrow bottle conveyor 2 driven by a driving device 101 made of an electric motor or the like to a conveyor 3 composed of five rows in a single row state from the direction of arrow A. For example, a group of about 20 groups are sequentially sorted into five rows by a sorting device 4 such as that disclosed in Japanese Patent Application Laid-Open No. 2000-272743.

  The decelerating conveyor unit 5 disposed downstream of the conveyor 3 is composed of four stages of conveyors 51, 52, 53, 54 driven by driving devices 102, 103, 104, 105 each consisting of an electric motor or the like. 2, the conveyance speed is decelerated at a stepwise speed ratio from the conveyor 51 having substantially the same conveyance speed, and the conveyance speed is such that the bottle 1 is in close contact with the conveyor 54. The specific conveyance speed of the conveyor 54 is about one fifth of the conveyance speed of the continuously feeding bottle conveyor 2.

  A speed increasing accumulating conveyor section 6 is disposed downstream of the speed reducing conveyor section 5, and the speed increasing accumulating conveyor section 6 is conveyors 61, 62, 63 driven by driving devices 106, 107, 108 made of electric motors, respectively. It consists of three stages. Encoders 206, 207, and 208 are provided on the drive shafts of the drive devices 106, 107, and 108, respectively, and signals such as the rotation speed and rotation amount of each encoder 206, 207, and 208 are taken into the control device 10, and A command is issued from the control device 10 to the driving devices 106, 107, 108, etc., so that the conveyors 61, 62, 63 and the other conveyors, stopping and increasing / decreasing of the conveying speed are controlled. Note that illustration of signal lines from the control device 10 to each drive device is omitted. (same as below.)

  Conveying speeds of the conveyors 61, 62, and 63 are such that if there is room for accumulation of the bottle 1 in each conveyor, the target accumulating capacity is set so that the distance before and after the bottle 1 is twice the diameter of the bottle 1. In this case, the conveyance speed is set to about three times that of the conveyor 54, and the conveyance speed can be appropriately selected according to the target accumulating ability. In addition, when the conveyor 63 becomes full with the bottle 1, the conveyor 63 is controlled to stop. Furthermore, when the downstream conveyor is full of bottles 1 or when the downstream conveyor is stopped, control such as stopping or decelerating the conveyor 63 can be performed.

  A decelerating and accumulating conveyor unit 7 is disposed downstream of the speed increasing and accumulating conveyor unit 6, and the decelerating and accumulating conveyor unit 7 is driven by a driving device 109 including an electric motor and the like, and a driving device 111 including an electric motor and the like. , 112, 113, 114, 115 are composed of three stages: a conveyor 72 driven in each row, and a conveyor 73 driven by a driving device 116 composed of an electric motor or the like.

  Encoders 209, 211, 212, 213, 214, 215, and 216 are provided on the drive shafts of the drive devices 109, 111, 112, 113, 114, 115, and 116, respectively. Is taken into the control device 10, and a command is issued from the control device 10 to the drive devices 109, 111, 112, 113, 114, 115, 116 to determine the conveyance, stop, and conveyance speed of the conveyors 71, 72, 73. The acceleration / deceleration is controlled. In addition, the conveyor 72 is configured to individually control five rows of conveyance, stop, and conveyance speed increase / decrease control.

  Further, when the bottles 1 are being conveyed, the conveyors 71, 72, and 73 are 10% to 50% faster than the conveyor 54, and can be selected according to the purpose of the accumulation control. Thus, depending on the clogging state of the bottle 1 of the downstream conveyor, the conveyance speed is controlled to be reduced and stopped.

  The driving devices 101, 102, 103, 104, and 105 are also controlled to carry the entire line in response to a command from the control device 10, but will not be described in detail.

  11, 11, 13, 14, and 15 indicate conveyor rows divided into five rows, and each row after the speed reduction conveyor section 5 is divided by straight or broken line bottle guides (not shown). .

Based on FIG. 7, the boundary part structure before and behind each conveyor of the deceleration conveyor part 5, the acceleration accumulator part 6, and the deceleration accumulation conveyor part 7 is demonstrated. In FIG. 7, the conveyor 61 includes five rows of conveyors 611, 612, 613, 614, and 615, with the start end being 610 and the end being 619. The conveyor 62 is composed of five rows of conveyors 621, 622, 623, 624, and 625, the start end of which is 620 and the end is 629. At the boundary between the conveyors 61 and 62, the conveyors 611 to 615 and 621 to 625 of each row overlap each other at the end 619 and the start end 620. For example, the bottle 1 conveyed on the conveyor 611 has the overlap. It is guided to the conveyor 621 by a bottle guide (not shown).
From the conveyor 51 to the conveyor 73, it has the same boundary part structure.

  Downstream of the decelerating and accumulating conveyor unit 7, a sizing conveyor 81 for the case packer 8 is arranged. A predetermined number or more of the squeezed bottles 1 are arranged on the sizing conveyor 81 by the case packer 8. It is packed in a case (not shown).

Next, the operation of the accumulator conveyor control method and apparatus according to this embodiment will be described.
In FIG. 1, a group of about 20 bottles 1 are transferred in stages from the bottle conveyor 2 to the conveyor 3 and distributed to the column 11 out of the five columns that are sequentially distributed by the sorting device 4. When the speed reaches the conveyor 54 of the decelerating conveyor unit 5 that is decelerated in four stages, the group is naturally conveyed in a substantially close contact state in order from the top bottle due to the deceleration. Similarly, when one group of bottles 1 distributed to the rows 12, 14, 15, 13 of the five rows reaches the conveyor 54, each group is transported in an almost intimate state in order from the top bottle, As shown in the figure, the five rows from the conveyor 54 toward the conveyor 53 are in a natural close contact state in a similar manner.

  Here, since the conveyance speed of the conveyor 54 is about one fifth of the conveyance speed of the bottle conveyor 2, the bottle 1 is in close contact with the conveyor 54 over the five rows 11 to 15. The bottles 1 are transported with the conditions almost even.

  In the acceleration accumulator section 6, if there is room for accumulation, the bottle 1 sent out from the conveyor 54 is spaced at the front and rear because the conveying speed of the conveyor 61 is increased more than the conveyor 54. Be transported. When the speed ratio between the conveyor 61 and the conveyor 54 is large, the accumulating capacity of the bottle 1 is increased due to the large space between the front and back of the bottle 1. Further, since the bottles 1 are in close contact with each other across the rows 11 to 15 by the conveyor 54, the bottles 1 are separated at equal intervals in the front and rear by the conveyor 61 (hereinafter referred to as "separated"). The transported state (expressed as being in a state) is roughly even across the rows 11-15.

  In the acceleration accumulator section 6, signals such as the rotation speed or conveyor speed of each drive shaft of the drive devices 106, 107, and 108, and the amount of rotation from a certain time are sent to the encoder 206 provided on the drive shaft of each drive device. , 207, 208 to the control device 10, the amount of the bottle placed on each conveyor is calculated from the distance traveled by the bottle 1 from the head of the conveyor, the speed of the conveyor, etc. It has a function of a full detection sensor that assumes that the bottle 1 is full when the amount of the upper bottle placed reaches a predetermined amount, and the conveyor is stopped and the conveying speed of the upstream conveyor of the conveyor is reduced. It is possible to control such as. Note that the setting of the full amount may be changed from a full state to a state with a slight margin.

  When the five rows of bottles 1 that have been conveyed separately by the acceleration accumulator section 6 are sent to the deceleration accumulator section 7, the acceleration accumulator section 6 is in a conveying state. The bottle 1 conveyed by the speed reduction of the conveyor 71 is conveyed in close contact with the bottle 1 in front without giving bottle pressure.

  Also in the deceleration accumulator section 7, signals such as the rotation speed or conveyor speed of each drive shaft of the drive devices 109, 111 to 115, 116, the rotation amount from a certain time are provided on the drive shaft of each drive device. Obtained from the encoders 209, 211 to 215, and 216 into the control device 10, the amount of bottles placed on each conveyor is calculated from the distance traveled by the bottle 1 from the top of the conveyor and the speed of the conveyor. If the calculated bottle placement amount on the conveyor does not reach the predetermined amount, the bottle 1 is in the transport state from the conveyor 51 to the conveyor 73. FIG. 1 shows this conveyance state.

  When the calculated amount of bottles placed on the conveyor reaches a predetermined amount, it has a function of a full detection sensor that assumes that the bottle 1 is full, stops the conveyor, Controls such as reducing the transport speed.

  When the bottle adjusting conveyor 81 is full, the conveyor 73 is controlled to be stopped in order to stop the replenishment of the bottle 1 from the conveyor 73 of the decelerating and accumulating conveyor unit 7. In connection with this, conveyance of the bottle 1 from the conveyor 72 is also stopped.

  Control is performed so that the bottle 1 is replenished to the bottle sorting conveyor 81 when a predetermined number or more of the bottles 1 are packed on the bottle conveyor 81 by the case packer 8 and packed in a case (not shown). However, at this time, since the conveyor 73 conveys the bottle 1 in a decelerated state, the bottle 1 is naturally closely conveyed to the bottle 1 on the bottle adjusting conveyor 81.

  Further, when the bottles 1 are transported from the conveyor 72 to the conveyor 73, if the five rows of the bottles 1 are transported at a time, a large force may act on a bottle stopper (not shown) of the bottle conveyor 81 due to the bottle pressure. However, in this embodiment, since the conveyors divided into the rows 11 to 15 of the conveyor 72 are sequentially driven to transport the bottles 1 to the conveyor 73 side, the bottles 1 acting on a stopper (not shown) of the bottle sorting conveyor 81 are provided. The force due to the bottle pressure is extremely small by being sequentially conveyed for each row. FIG. 2 is a diagram illustrating a conveyance state immediately before the conveyor 73 is stopped just before the conveyor 73 is full.

  Here, when the row 13 of the conveyor 73 reaches a full state, the drive of the row 13 of the conveyor 72 corresponding thereto is stopped, and the rows 15, 14, 12, and 11 are sequentially conveyed and stopped in the same manner. When the bottle is full, the replenishment of the bottle 1 from the conveyor 72 to the conveyor 73 is completed. At this point, the conveyor 71 is driven in a decelerating state to transport the bottle 1, and the bottle 1 is replenished to the conveyor 72. To do. FIG. 3 is a diagram showing this conveyance state.

When the conveyor 71 becomes full, the conveyor 71 is controlled to stop driving.
On the other hand, when the bottle 1 is not full in the most downstream conveyor 63 of the speed increasing accumulator section 6, as shown in FIG. 3, the bottle 1 is separated and conveyed. When the conveyor 71 is stopped, the conveyor 71 comes into close contact with the subsequent bottle 1 of the conveyor 71.
In this case, if the conveyance speed of the bottle 1 is in a steady increase state, an impact is given when the bottle 1 comes into close contact with the front bottle 1, so when the conveyor 71 is stopped, By controlling the conveyance speed of the conveyor 63 to be reduced to a speed corresponding to the conveyance speed of the conveyor 54, the bottles 1 can be brought into close contact with each other in a natural state.

  In this case, since the conveyor 63 is in a decelerating state, the bottles 1 are conveyed in a state of being in close contact with the upstream head portion of the conveyor 63 in order. The conveyor 63 is controlled to stop when the amount of bottles placed on the conveyor 63 corresponds to a full state or a set amount close to full. Therefore, the front bottle 1 can be approached as a group without applying bottle pressure. FIG. 4 is a diagram showing this state.

  Similarly to the case where the conveyor 71 is stopped and the conveyor 63 is driven and controlled, when the conveyor 63 is stopped, the conveyor 62 is decelerated and stopped. That is, the bottles 1 are transported in a state where the bottles 1 are naturally in close contact with each other in a decelerating state of the conveyor 62, and the conveyor 62 is stopped when the bottle 1 becomes full. FIG. 5 is a diagram showing a state when the conveyor 62 is full and stopped.

When the conveyor 63 is stopped and the conveyor 62 is driven and controlled, when the conveyor 62 is stopped in a full state, the conveyor 61 is controlled to decelerate and stop. FIG. 6 is a diagram illustrating a state when the conveyor 61 is full and stopped.
When the conveyor 61 stops in a full state, the decelerating conveyor unit 5 is controlled so as to decelerate or stop at a steady speed.

  As described above, the embodiment according to the present invention is a multi-stage conveyor that decelerates the speed reduction conveyor unit 5 in stages, and the conveyance speed is such that the bottle 1 naturally adheres at the final stage. The bottles 1 supplied to each row of the conveyor can be brought into a state of being in close contact with each other, and the bottle pressure applied to the bottles 1 can be extremely reduced. Moreover, since each said row | line | column can be made into the group of the bottle 1 which adhere | attached naturally naturally, the length of the deceleration conveyor part 5 can be utilized efficiently without waste.

  In the acceleration accumulator section 6, multiple rows of conveyors can be accumulated in a separated state with evenly spaced intervals before and after the bottle 1, so the accumulation function is efficient and the conveyor length is not wasted. Can be used efficiently.

  Further, in the acceleration accumulator section 6 and the deceleration accumulator section 7 downstream thereof, an encoder for measuring the rotational speed of the drive shaft, the amount of rotation from a certain time, etc. is provided on the drive shaft of each conveyor. Since the amount of bottles can be calculated by the control device, when the bottles on the conveyor are full, the conveyor can be stopped or the upstream conveyor speed can be reduced to reduce the upstream conveyor speed. Conveyor transport control can be made efficient, such as transporting in a state of close contact with the head part, and full detection is made before the contact bottle line actually contacts the already stopped bottle line, There is an effect that it can be accumulated without applying bottle pressure to the already stopped bottle row.

  In the present embodiment, the case where the encoder is provided in the acceleration accumulating conveyor unit 6 and the deceleration accumulating conveyor unit 7 has been described. However, instead of the encoder, the conveyance state of the bottle is detected by another detection device and the conveyance control is performed. Of course, you may.

  Moreover, in the said embodiment, the bottle 1 conveyed from the supply bottle conveyor 2 is divided into five rows by the distribution apparatus 4, and the deceleration conveyor part 5, the acceleration accumulator part 6, and the deceleration accumulation conveyor part 7 are illustrated. Although the case where the sheet is divided into five rows and conveyed by the guide not to be described has been described, the distribution apparatus 4 may not be used. In this case, the accumulator conveyor is configured as a wide conveyor that is not divided into rows by guides, but the conveyor calculated by the encoder and the control device is also used in this case. Although it is possible to control the conveyance of the accumulator similar to the above based on the amount of the bottle placed on the upper side, the control method is similar to that described above, and the detailed description is omitted.
