Description

The present invention is a filling apparatus having a mechanism for intermittently conveying a container to be filled in order to perform at least one work process of filling a container with a filling material and then filling and packaging such as covering the container with a lid. The present invention relates to a packaging machine that completes the filling of a container by weight filling, which is performed based on the measurement result of the weight of the filling filled in the container.

In Patent Document 1, for the purpose of eliminating variations in the filling amount when filling a container with a filling such as a liquid and shortening the filling time, first, most of the predetermined filling amount is not weighed. Shorten the filling time by roughly filling with , then weigh the container with a weighing device, and the difference between the weight value and the predetermined weight value of the container filled with a fixed amount of filling (shortage weight) A filling method and an apparatus therefor are disclosed.

Japanese Patent Application Laid-Open No. 2002-274503

However, according to this conventional filling method, there is a large difference in the additional amount of the insufficient weight depending on the filling accuracy at the time of rough filling. As a result, the effect of shortening the filling time could not be obtained.

In addition, intermittent transportation that repeats moving and stopping generates intermittent large accelerations. Therefore, when the liquid is filled, the liquid surface fluctuates greatly, making it difficult to accurately measure the weight. In other words, it was necessary to wait for the state of the liquid surface to stabilize in order to measure the weight accurately, which prevented quick surveying. Further, no apparatus has been proposed for measuring the weight of a container being conveyed while filling it.

Furthermore, this conventional method is premised on the fact that there is no difference in the weight of the container itself. , there was a concern that there would be a difference in filling amount.

Further, conventionally, after the containers that are intermittently conveyed are roughly filled by time filling, based on the measurement result using the measuring means arranged at the intermittent conveyance stop position in the final region of the conveying route, Also known is a filling and packaging machine that fills the remaining amount up to a predetermined weight by weight filling. However, according to this filling and packaging machine, it is necessary to wait until the roughly filled filling settles down so as not to disturb the scale when measuring by the measuring means. In addition, when the filling and packaging machine is configured to simultaneously operate a plurality of filling heads to fill a plurality of containers at the same time, in time filling, considering the individual differences of each filling head, a plurality of Of the filling heads, it was necessary to perform filling according to the filling head with the slowest filling speed, and the adjustment was not easy. Since the filling speed varies depending on the viscosity of the filling material, it is particularly difficult to adjust the initial settings for rough filling by time filling.

Further, the weight of the container itself cannot be measured before filling using the measuring means arranged at the intermittent transfer stop position in the final area of the transfer route, and the weight difference of the container itself cannot be taken into account. . Of course, it is possible to dispose the measuring means at a stop position other than the intermittent transfer stop position in the final area of the transfer route, but it goes without saying that the cost will be increased.

The present invention has been made in view of such problems. To provide a filling and packaging machine having a simple structure and operation, capable of shortening the filling time and improving the accuracy of the filling amount by completing the filling as follows.

In order to achieve the above object, the filling and packaging machine of the present invention includes a filling work step of filling a filling and at least one step after the filling work step among a plurality of steps for filling and packaging a container. A filling and packaging machine that performs two work processes while conveying the container , and is located between a receiving position for the container provided upstream in the conveying direction and a delivery position for the container provided downstream. and a container holding part for holding the container intermittently moves in a first movement path in which a filling area for performing the filling work process and a work area for performing at least one work process after the filling work process are arranged . A first container conveying mechanism capable of intermittently conveying the containers, and a second container capable of continuously conveying the containers on a second movement route parallel to the first movement route in the filling area in plan view. a conveying mechanism, a container transfer mechanism for transferring the container between the first movement path and the second movement path, and a filling capable of filling the container moving on the second movement path with a filling via a nozzle. and wherein the first moving path is a circulating path of the container holding portion formed on the outer peripheral edge of a wheel that is horizontally arranged so as to be intermittently rotatable about a cylindrical shaft-shaped first rotating body. wherein the second movement path is formed outside the first movement path and on a circumference concentric with the first movement path, and the second container transport mechanism is at least during filling to completion of filling. It has a measuring means capable of measuring the weight of the container and its filling up to, and the control unit always adjusts the filling amount by weight filling based on the measurement result of the measuring means and performs filling. and controlling the measuring means and the filling means.

In the filling and packaging machine of the present invention, in the filling area, the containers are delivered from the first movement path to the second movement path by the container delivery means, and while the containers are continuously transported on the second movement path by the second container transport mechanism. Moreover, the filling is completed by measurement by the measuring means, and after the completion of filling, the container transfer mechanism transfers the container from the second movement path to the first movement path, and then conveys the first container on the first movement path. The mechanism intermittently transports the filled container to the next work area. As the work area next to the filling area, for example, a sealing work area for sealing during a temporary stop due to intermittent transportation, a print area for stamping the date of manufacture, etc. can be assumed.

As described above, according to the filling and packaging machine of the present invention, even if the filling and packaging machine as a whole has a mechanism for intermittently conveying containers, the filling area can be surveyed while continuously conveying. The acceleration of intermittent transportation does not affect the filling material, so that the material can be quickly surveyed and the filling time can be shortened.

Furthermore, according to the filling and packaging machine of the present invention, the structure and operation of the device can be simplified by using the second container conveying mechanism as the measuring means. In addition, since it is possible to perform filling while measuring the filling amount from the start of filling to the end of filling, it is possible to eliminate variations in the filling amount and perform filling with extremely good accuracy. For example, by employing a suspension scale in a container transport mechanism having a neck grip, the weight of the container suspended from the neck gripper and its filling amount can be measured.

The second container transport mechanism includes bottle suspension means for suspending and holding the bottles in the filling area , the measuring means is disposed in the bottle suspension means, and the container transfer mechanism is composed of the bottle suspension means, slide means for moving the bottle suspension means horizontally forward and backward, and a suspension means elevating mechanism for adjusting the position of the bottle suspension means in the height direction. and

According to the filling and packaging machine of the present invention, by using the container transfer mechanism as the container transfer mechanism, the structure and operation of the device are simplified.

Then, the control unit measures the weight of the container itself by the measuring means before the start of filling, and controls the measuring means and the filling means so that the weight of the container itself is reflected on the measurement result and filled to a predetermined filling amount. It is characterized by

According to the filling and packaging machine of the present invention, even if it is assumed that the weight of each container varies, it is possible to perform correct filling without causing a difference in the filling amount.

As described above, according to the filling and packaging machine of the present invention, the structure and operation are simple, the filling time can be shortened, and the precision of the filling amount can be improved.

Next, the operation of the container filling machine of this embodiment and its drive control (filling method) will be described.

As described above, the first movement route R1, which is the circling route of the pockets 11 of the wheel 12, intermittently rotates the 24 pockets 11 by 15 degrees. Therefore, 24 stop positions for the pocket 11 are provided at intervals of 15° on the first movement route R1. Then, as shown in FIG. 1, when the stop position in the 6 o'clock direction is set as the first stop position and provided clockwise from there to the 24th stop position, this first stop position is the conveying means 102 arranged upstream. , and is the most upstream position on the first movement route R1. The twenty-fourth stop position is the delivery position OP of the bottle B to the conveying means 103 arranged downstream, and is the most downstream position on the first movement route R1.

Further, in this embodiment in which six bottles B are filled with the filling liquid at one time, the filling area is between the third stop position and the thirteenth stop position, and the second movement route R2 is a plane. When viewed, it is provided in an arc shape along the outer circumference of the first movement route R1.

1 to 6, the 17th stop position is the cap supply area where the cap feeder 104 is arranged, and the 19th and 20th stop positions are where the seaming device 105 is arranged. The seam tightening area and the 22nd stop position are an inspection area in which an inspection device 106 is arranged .

Each bottle B supplied from the receiving position IP into the first movement route R1 is intermittently rotated clockwise by 15° at an arbitrary speed along with the wheel 12 together with the first rotor 13 by the driving of the first servomotor 14. to sequentially move clockwise from the first stop position by one stop position.

The control unit controls the drive of the second servomotor 32, the first bottle B1 among the six bottles to be filled at this time moves to the eighth stop position in the filling area, and the sixth bottle B6 moves to the second stop position. When it is moved to the 3 stop position, the second rotating body 31 is rotated so that the six hanging means elevating mechanisms 34 correspond to the six bottle hanging means 33 corresponding to the respective bottles B1:B6. Also, the transport guide wall 57 is positioned at a raised position separating the first movement route R1 and the second movement route R2 (see FIG. 1).

Triggered by the movement of the first bottle B1 to the eighth stop position in the filling area and the movement of the sixth bottle B6 to the third stop position, the controller controls the motor 38 of the lifting means lifting mechanism 34. is driven to rotate the screw shaft 37, and the support member 40 is lowered along the screw shaft 37 and the guide portion 42, thereby opening the pair of arms 45 so that the neck portion of the bottle B can be held. The chuck 46 of the hanging means 33 is positioned at the height of the mouth/neck portion of the bottles B1:B6 stopped at the third stop position to the eighth stop position, and the transport guide wall 57 is aligned with the first movement path R1. It is positioned at a lowered position that opens the space between it and the second moving route R2 (see FIG. 2).

Subsequently, the control unit drives the arm opening/closing actuator that opens and closes the pair of arms 45, closes the pair of arms 45, holds the mouth/neck portion of the bottle B with the chuck 46, and then slides the slide means 48 as described above. By driving the slide actuator, the bottle hanging means 33 holding the respective bottles B1:B6 are radially advanced from the center of the second rotating body 31, and the motor 38 of the hanging means elevating mechanism 34 is driven. By rotating the screw shaft 37, the support member 40 is lifted along the screw shaft 37 and the guide portion 42, and the bottles B1:B6 are suspended on the second movement route R2. Also, the transport guide wall 57 is positioned at the raised position separating the first movement route R1 and the second movement route R2.

In this way, when the suspended bottles B1:B6 are delivered to the second movement route R2 and are suspended, the control unit drives the first servomotor 14 to rotate the first rotating body 13 and the wheel. 12 is intermittently rotated clockwise by 15° at an arbitrary speed. At this time, the pocket 11 holding the bottles B1:B6 on the wheel 12 also intermittently moves on the first movement route R1, and the bottle B6 is placed next to the bottle B6 among the six bottles B to be filled next. is supplied from the receiving position IP into the first movement route R1 (the supply of the bottles B continues sequentially thereafter).

Then, the pocket 11 holding the bottle B1 moves to the 13th stop position in the filling area, and the pocket 11 holding the sixth bottle B6 intermittently moves to the 8th stop position. , the continuously conveyed bottles B1:B6 are filled with the filling liquid on the second movement route R2.

That is, the control unit drives the nozzle lifting actuator 51 of the nozzle lifting means 52 provided at the end of the support member 40, and the liquid storage tank (not shown) of the filling means 49 provided near the filling packaging machine 1. ) is lowered from its standby position and inserted into the bottles B1:B6, and the supply valve (not shown) of the filling means 49 is opened and closed. Controlled filling (see Figure 3).

At this time, in this embodiment, the control unit controls the filling means 49 based on the data of the weight of each bottle B1 measured by the hanging scale of the measuring means 55 provided in the bottle hanging means 33 to perform weight filling. I do. In this manner, according to the filling of the present embodiment, in which the filling amount is measured while the bottle B is continuously conveyed, and the filling is performed, the acceleration during the intermittent conveyance of the bottle B does not affect the filling, and the measurement can be performed quickly. and the filling time can be shortened.

Filling may be controlled by measuring the weight of the tare of the bottle B and the total weight of a predetermined filling amount, or by measuring the weight of each tare when each bottle B is suspended. Alternatively, control may be performed so that each bottle B is always filled with the same amount of filling liquid. According to the latter filling method, even if it is assumed that the weight of each bottle B varies, it is possible to fill the bottles correctly without causing a difference in the filling amount.

Also, on the second movement route R2, the control unit first fills an amount slightly short of the predetermined filling amount by rough filling by "timed filling", and then the remaining amount is measured by the measuring means 55. The measuring means 55 and the filling means 49 may be controlled so as to perform adjustment filling by weight filling based on.

According to this filling method, it is possible to shorten the time required for filling when the amount slightly less than the target weight is initially roughly filled, and to perform adjustment filling by weight filling over a necessary and sufficient time for filling the remaining amount. Therefore, the accuracy of the filling amount can be improved.

In this embodiment, the control unit drives the nozzle elevation actuator 51 to raise the nozzles 50 inserted into the bottles B1:B6 according to the filled amount, and after the filling is completed, the bottles B1:B6 Control is performed to pull it out from inside and return it to the standby position. Further, when the filling is completed, the conveying guide wall 57 is positioned at the lowered position where the space between the first moving route R1 and the second moving route R2 is opened (see FIG. 4). Note that the transport guide wall 57 functions as an outer guide for the first movement route R1.

Each of the bottles B1:B6 is completely filled before it moves to the positions on the second movement route R2 corresponding to the 13th to 8th stop positions in the filling area of the first movement route R1. When each of the bottles B1:B6 moves to the positions on the second movement route R2 corresponding to the 13th stop position to the eighth stop position in the filling area of the first movement route R1, on the first movement route R1, the bottles The pocket 11 holding B1 moves to the thirteenth stop position in the filling area, and the pocket 11 holding the sixth bottle B6 intermittently moves to the eighth stop position. Therefore, the control section drives the slide actuator of the slide means 48 to retract the bottle suspension means 33 holding the respective bottles B1:B6 toward the center of the second rotating body 31, and the suspension means elevating mechanism The motor 38 of 34 is driven to rotate the screw shaft 37, the bearing member 40 is lowered along the screw shaft 37 and the guide portion 42, and the bottles B1 and B6 are moved intermittently along the first movement path R1. It is returned to the original pocket 11 from which it was transported (see FIG. 5).

The bottles B1 and B6 that have been completely filled are driven by the first servomotor 14 to intermittently rotate the wheel 12 clockwise by 15° together with the first rotating body 13 at an arbitrary speed, thereby moving the bottles B1 to B6 along the first moving path R1. At the 17th stop position, the cap supply device 104 temporarily covers the mouth of each bottle B with a cap, and at the 19th and 20th stop positions, the cap is wound by the seaming device 105. After being tightened and finally inspected by the inspection device 106 at the 22nd stop position, it is discharged to the delivery position OP of the conveying means 103 arranged downstream at the 24th stop position.

Further, after returning the filled bottles B1:B6 to the original pockets 11 intermittently conveyed on the first movement route R1, the control unit controls the driving of the second servomotor 32, The six suspension means elevating mechanisms 34 are transported again from the eighth stop position to the third stop position on the first movement route R1, and are ready to hold the next six bottles B1':B6' to be filled. , the second rotating body 31 is rotated in reverse, and the conveying guide wall 57 is positioned at the raised position separating the first movement path R1 and the second movement path R2, and returned to its original state (see FIGS. 6 and 1). .
