DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an article transport processing apparatus according to the present invention will be described below with reference to the drawings. FIG. 1 is a schematic perspective view of an article transport processing apparatus according to this embodiment. The article conveying/processing apparatus according to the present embodiment is used for conveying a container and filling the container with a filler such as a liquid. As shown in FIG. 1, the article conveying and processing apparatus A in this embodiment includes a conveying section 1, a filling section 3 (example of the second processing section in the present invention), and a capping section 5 (example of the first processing section in the present invention). ). Both the filling section 3 and the capping section 5 are provided on the conveying path of the conveying section 1, and the filling section 3 is arranged on the upstream side. A bottle washing unit for washing the container may be arranged upstream of the filling unit 3 .

In this embodiment, the transport unit 1 is configured to perform so-called two-row transport, in which two containers C are transported side by side in a direction orthogonal to the transport direction (hereinafter referred to as a transport orthogonal direction). . Of course, the number of rows to be conveyed can be changed as appropriate, and can be determined according to the required processing capacity of the article conveying and processing apparatus and the processing capacity of the apparatus.

The filling unit 3 performs a process of filling the container C with a filling such as a liquid (an example of the second process of the present invention; hereinafter referred to as a filling process). The capping unit 5 performs a process of attaching a lid to the filled container C (an example of the first process in the present invention; hereinafter referred to as capping process). Note that these processes are performed while the container C is conveyed without stopping.

[Conveyor]
In this embodiment, instead of placing the containers C directly on a conveyor or the like and transporting them, the containers C are placed on carriers 9 and the plurality of carriers 9 are configured to be transported continuously. ing. Therefore, in this embodiment, a plurality of carriers 9 constitute a transport path.

[Career]
2 and 3 are a perspective view and an exploded perspective view of the carrier 9 in this embodiment. As shown in the figure, the carrier 9 includes a base plate 91, a mounting plate 92, a positioning member 93, a guide member 94, an operation member 95, a slide member 96 and a fixing member 98.

The base plate 91 is formed in a substantially plate shape, and the mounting plate 92 is fixed thereon. The mounting plate 92 is a portion on which the container C is mounted. As described above, in this embodiment, the containers C are conveyed in two rows, so the mounting plate 92 is formed in a size that allows two containers C to be mounted. Therefore, the base plate 91 and the mounting plate 92 are formed so that the dimension in the direction orthogonal to transport is larger than the dimension in the transport direction.

The mounting plate 92 is formed in a substantially rectangular parallelepiped shape having side walls 92a erected on four sides of a rectangular plate-like member and having an upper opening. Since the container C is placed on the mounting plate 92 and transported, even if the container C filled with liquid or the like falls over and the filling inside leaks out, the mounting plate 92 receives it. I can do it. Therefore, cleaning and the like can be completed simply by replacing the carrier 9, and a decrease in work efficiency can be suppressed. On the other hand, when the container C is placed directly on a conveyor or the like, there is a risk that the leaked filling material may flow out onto the conveyor when the container C is overturned. In that case, it takes time to clean the conveyor and the like, resulting in a decrease in work efficiency. In particular, when the filling material reaches the drive system of the conveyor, it takes a very long time to clean it.

Rail portions 91a extending in the transport direction are formed near both end portions of the base plate 91 in the transport orthogonal direction. Two slide members 96 are slidably provided on each of the two rail portions 91a. A fixed member 98 is fixed on each slide member 96 . Therefore, the fixed member 98 can be slid integrally with the slide member 96 along the transport direction on the rail portion 91a. In addition, when it is necessary to distinguish four fixing members, they are described as fixing members 981, 982, 983, and 984, respectively.

Approximately prismatic positioning members 931 and 932 extending in the direction orthogonal to the transport direction are provided on the upstream side and the downstream side in the transport direction, respectively. The positioning members 931 and 932 are referred to as the positioning member 93 when there is no need to distinguish between them. The positioning member 931 on the upstream side in the transport direction is suspended between a fixing member 981 and a fixing member 983, and both ends are screwed to the fixing members 981 and 983, respectively. Similarly, the positioning member 932 on the downstream side in the transport direction is also suspended between the fixing members 982 and 984, and both ends thereof are screwed to the fixing members 982 and 984, respectively. Therefore, when the fixing member 98 slides, the positioning member 93 also slides together.

Each positioning member 93 is provided with two pressing members 97 protruding inward along the direction perpendicular to the transport direction. Specifically, the positioning member 931 is provided with pressing members 971 and 972 , and the positioning member 932 is provided with pressing members 973 and 974 . In addition, the pressing members 971 and 973, and the pressing members 972 and 974 are arranged at the same position in the direction perpendicular to the transport direction. In other words, the pressing members 971 and 973 are arranged to face each other, and the pressing members 972 and 974 are arranged to face each other.

The pressing member 97 is supported by the positioning member 93 so that an inward biasing force acts thereon via an elastic member such as a spring. Therefore, when an outward force acts on the pressing member 97, the pressing member 97 is elastically displaced in the direction of the force, and elastically returns to its original position when the force is no longer applied.

An inner end surface of the pressing member 97 is formed with a concave portion 97a that is substantially V-shaped in plan view. Further, recesses 93a corresponding to the recesses 97a are formed on the upper and lower surfaces of the positioning member 93. As shown in FIG.

Approximately V-shaped operating members 951 and 952 are provided on both sides in the direction perpendicular to the transport direction. In addition, when it is not necessary to distinguish these, they are written as the operating member 95 . Each operating member 95 is composed of two flat plate rod-shaped members, and an insertion hole 95a is formed at one end of each flat plate rod-shaped member. A substantially V-shaped operating member 95 is constructed by inserting a bolt 95c through the insertion hole 95a in a state where the insertion holes 95a of the two flat plate rod members are overlapped. The operation member 95 is rotatable around the insertion hole 95a. Along with this rotation, the non-fixed end portions (hereinafter referred to as tip portions) of the flat plate rod-shaped member move toward or away from each other. In the following description, an operation in which the tip portions approach/separate from each other is referred to as a closing operation/opening operation, and a state in which the tips approach/separate from each other is referred to as a closed posture/open posture. Two ends of the operation member 95 are screwed and fixed to end surfaces of different fixing members 98 in the direction perpendicular to the transport direction. Specifically, the two ends of one operation member 951 are screwed to the end faces of fixing members 981 and 982 in the direction perpendicular to the conveying direction, and the two ends of the other operation member 952 are fixed members 983 and 983, respectively. It is screwed and fixed to the end face of 984 in the direction perpendicular to the transport direction.

A substantially plate-shaped guide member 94 is provided outside each operation member 95 . Both upper ends of the guide member 94 are screwed to the end surface of the base plate 91 in the direction perpendicular to the transport direction via spacers. A through groove 94a is formed in the center of the guide member 94 in the width direction so as to extend upward from the lower end. The position of the upper end of the through groove 94a is substantially the same as the position of the insertion hole 95a when the operating member 95 is in the open posture. Also, the width of the through groove 94 a is adapted to the diameter of the bolt 95 c inserted through the through hole 95 a of the operating member 95 .

In addition, two springs 95b are arranged in an X shape between the guide member 94 and the vicinity of the tip of each of the operation members 95 . The spring 95b applies force to the operating member 95 toward the open posture side. Therefore, when no other force acts on the operating member 95, the operating member 95 is in the open position.

[Filling part]
The filling section 3 has four filling heads 31 (an example of the second processing head in the present invention). Specifically, the four filling heads 31 are arranged two along the transport direction and two along the direction orthogonal to transport, that is, arranged in a 2×2 matrix. Since these four filling heads 31 can operate simultaneously, four containers C can be filled in one cycle. In this embodiment, the filling processing time for one container C of one filling head 31 (corresponding to the second processing time in the present invention) is 6 seconds. In other words, the filling unit 3 in this embodiment can fill four containers C in six seconds of one cycle, or 40 containers C in one minute.

The filling head 31 waits above the transport path, descends at the timing when the container C is transported to the filling position, and starts the filling process. Then, it is configured to perform the filling process while moving in the downstream direction as the container C is conveyed, and to return to the standby position on the upstream side in the conveying direction when the filling is completed.

[Capping part]
The capping section 5 has two capping heads 51 (an example of the first processing head in the present invention). Specifically, the two capping heads 51 are arranged one along the transport direction and two along the transport orthogonal direction, that is, arranged in a 1×2 matrix. Since the two capping heads 51 can operate simultaneously, two containers C can be capped in one cycle. In this embodiment, the capping processing time for one container C by one capping head 51 (corresponding to the first processing time in the present invention) is 3 seconds. In other words, the capping unit 5 in this embodiment can cap two containers C in three seconds of one cycle, or 40 containers C in one minute.

The capping head 51 waits above the transport path, descends at the timing when the container C is transported to the capping position, and starts the capping process. The capping process is performed while moving in the downstream direction as the container C is conveyed, and when the filling is completed, it returns to the standby position on the upstream side in the conveying direction.

[Conveyance of container: Placement of container]
The flow of a series of processing relating to filling of the container C in the article transport processing apparatus A will be described below. First, the transportation of the container C will be described. Two containers C are placed on the empty carrier 9 of the conveying section 1 of the filling section 3 located on the most upstream side of the article conveying and processing apparatus A. As shown in FIG. Although a manipulator can be used to place the container C, it is performed manually in this embodiment. At this time, the operating member 95 is in the open position, and the fixing member 98 to which the operating member 95 is fixed and the positioning member 93 fixed to the fixing member 98 are positioned at both ends in the transport direction.

In the article conveying and processing apparatus, when the number of articles to be processed per unit time increases, the conveying speed must be increased according to the increased number. When the articles are conveyed in one line, the rate of increase in the number of processing required is directly reflected in the conveying speed. That is, when the number of processed sheets is doubled, the transport speed must be doubled. However, when the containers C are artificially placed on the carrier 9, it becomes difficult to properly place the containers C when the transport speed of the carrier 9 exceeds a predetermined speed. This limits the capabilities of the article handling and processing apparatus. Further, when the conveying speed is increased, if the article is vertically long as in the present embodiment, it tends to fall over. Therefore, the transport speed of the carrier 9 cannot be increased beyond a predetermined speed.

On the other hand, by increasing the number of rows to be conveyed as in this embodiment, the increase in the number of required processes can be handled without changing the conveying speed or with a small increase in the conveying speed. can do. For example, considering the case of increasing the processing rate from 40 per minute in one row to 80 per minute, it is necessary to double the transport speed in the case of one row transport. There is On the other hand, if the number of conveying columns is changed to two, it becomes unnecessary to change the conveying speed.

[Conveyance of containers: Positioning of containers]
The container C to be transported must be placed in a predetermined position on the carrier 9 so that it is properly positioned with respect to the processing head. However, as described above, in this embodiment, the container C is placed on the carrier 9 being conveyed, and it is difficult to place the container at a predetermined position. Therefore, in this embodiment, the carrier 9 performs the positioning process of the container C. As shown in FIG. A specific positioning process will be described below with reference to FIG.

First, an operator places two containers C on the placing plate 92 of the carrier 9 to be conveyed. In this case, it is sufficient to place the device in the vicinity of the appropriate placement position instead of placing it in the appropriate placement position. Specifically, it is sufficient to place it between the pressing members 97 facing each other. This state is shown in FIG. 4(a).

The carrier 9 on which the two containers C are placed is transported by the transport unit 1 toward the filling position, and the positioning operation of the containers C is performed on the way. Specifically, first, force is applied to the bolt 95c in the downward direction. As a result, the bolt 95c is pulled down along the through groove 94a of the guide member 94. As shown in FIG. Along with this, the insertion hole 95a through which the bolt 95c is inserted is also pulled down. At this time, the rectilinear motion of the insertion hole 95a is converted into a rotating motion (closing motion) of the two flat plate rod members, and the operating member 95 is displaced to the closed position. Further, since the distal end of the operation member 95 is fixed to the fixed member 98, the fixed member 98 is fixed to the slide member 96, and the positioning member 93 is fixed to the fixed member 98, the operation member 95 is closed. As the posture is changed, the fixing members 98 facing each other are slid toward each other, and the positioning members 931 and 932 are slid toward each other.

When the positioning members 931 and 932 approach each other, the pressing members 971 and 973, and the pressing members 972 and 974, which are opposed to each other, approach each other. At this time, the container C placed between the pressing members 971 and 973 and the container C placed between the pressing members 972 and 974 are sandwiched between the opposing pressing members 97 . be The container C sandwiched between the opposing pressing members 97 moves along the substantially V-shaped concave portion 97a in plan view formed in the pressing member 97, and the center of the container C and the center of the concave portion 97a in the direction orthogonal to the transport direction are aligned. match. This enables positioning in the transport direction and the transport orthogonal direction. The state at this time is shown in FIG. 4(b). When the container C is sandwiched between the two pressing members 97, the pressing member 97 is elastically displaced by the reaction force from the container C, so that the impact on the container C can be absorbed.

Next, when the downward force acting on the bolt 95c is released, the operating member 95 is displaced to the open position by the force of the spring 95b. Along with this, the opposing fixing members 98 are slid apart from each other, and further the positioning members 931 and 932 are slid away from each other. As a result, the container C on the mounting plate 92 is placed in a free state. The state at this time is shown in FIG. 4(c).

In this embodiment, the cam 95d is attached to the bolt 95c, and the action of the cam acts on the bolt 95c to apply a downward force to the bolt 95c. may apply a force in the lifting direction.

Such a container C to be processed is simply conveyed while being placed on a conveyor, or as disclosed in Japanese Patent Application Laid-Open Nos. 2000-327090 and 2015-020762. It is generally fixed to a carrier and transported. In the former case, it is necessary to position the container C at the processing position, and when the container filled with the filling is overturned, there is a risk that the leaked filling may reach parts of the conveyor. There is a problem that it takes time to clean. On the other hand, in the latter case, the container C may be placed on the carrier 9 at an angle, which causes inconvenience during subsequent processing. In order to solve such a problem, in this embodiment, the container C is placed on the carrier 9 and transported. Therefore, even if the container C filled with the filling material is overturned and the filling material leaks out, there is a high possibility that the filling material will flow out onto the mounting plate 92 . Therefore, in that case, it is only necessary to stop the conveying section 1 and replace the carrier 9, so that it is possible to avoid a decrease in work efficiency. Also, the container C being transported is fixed by the pressing member 97 at the time of positioning, but this is only temporary and the container C is immediately unfixed. Therefore, the container C is transported to the processing position while being positioned and placed straight on the carrier 9 .

[Goods Conveying Processing: Processing for Containers]
FIG. 5 is a diagram schematically showing a state in which the container C is subjected to filling processing and capping processing. Note that the right direction in the drawing is the transport direction. The figure shows how two containers C are placed on one carrier 9 and transported. Also shown are four filling heads 31 arranged in a 2×2 matrix and capping heads 51 arranged in a 1×2 matrix.

FIG. 5(a) shows a state where the filling head 31 and the capping head 51 are at the standby position at time t=0. In this state, containers C11 and C12 have been capped, and containers C21, C22, C31, C32, C41 and C42 have been filled but not capped. Also, the containers C51, C52, C61, and C62 are in a state in which the filling process has not been completed.

The container C in such a state is conveyed toward the downstream side in the conveying direction together with the carrier 9, and at the timing when the container C reaches each processing position, the filling head 31 and the capping head 51 are lowered to the respective processing positions ( See FIG. 5(b)). Here, the capping process is started for the containers C21 and C22, and the filling process is started for the containers C51, C52, C61 and C62.

In this embodiment, the capping process takes 3 seconds, so at time t=3, the capping process for the containers C21 and C22 is completed, and the capping head 51 returns to the standby position. On the other hand, since the filling process takes 6 seconds, about half of the filling processes for the containers C51, C52, C61, and C62 have been completed (see FIG. 5(c)).

Next, when the containers C31 and C32 reach the capping position, the capping head 51 descends to the capping position. At this time, the filling process for the containers C51, C52, C61, and C62 continues (see FIG. 5(d)).

In this embodiment, since the filling process takes 6 seconds, the filling process for the containers C51, C52, C61, and C62 is completed at time t=6 seconds, and the filling head 31 returns to the standby position. At this time, since the capping process for the containers C31 and C32 is also completed, the capping head 51 also returns to the standby position (see FIG. 5(e)). This state is the same as in FIG. 5(a), and the processing of FIGS. 5(b) to 5(e) is repeated.

As described above, in this embodiment, the time for the filling process and the time for the capping process are different, but by adjusting the number of filling heads 31 and the number of capping heads 51, each process can be synchronized. there is Specifically, the number of filling heads 31 with a long processing time is multiplied by 2, which is the number of capping heads 51 with a short processing time, by 2 (6 seconds/3 seconds), which is the ratio of the processing time. I have to.

By configuring in this way, the number of treatments per unit time in each treatment is the same, that is, the treatment time for one container C is the same in each treatment. In the above example, the time required for the filling process is 6 seconds, and the filling process is performed simultaneously by the four filling heads 31. Therefore, the filling process time for one container is 1.5 seconds, and the time for one carrier 9 is 1.5 seconds. The filling process time is 3 seconds (1.5 seconds x 2). On the other hand, the time required for the capping process is 3 seconds, and since the capping process is performed simultaneously by the two capping heads 51, the capping process time for one container is 1.5 seconds, and the capping process time for one carrier 9 is 1.5 seconds. is 3 seconds (1.5 seconds x 2), which is the same as the filling processing time. As a result, there is no need to perform processes such as synchronization of each process, control of transportation, and accumulation of articles, and efficient article transportation processing can be performed.

Table 1 shows the relationship between the throughput of the article conveying and processing apparatus A and the number of processing heads of each apparatus. The processing capacity (processing time) of each processing unit is assumed to be the same as that of the present embodiment. Various methods of arranging the processing heads when the number of processing heads is increased are conceivable, but increasing the number of arrangement in the conveying direction increases the conveying speed. Therefore, the number of arrangements in the conveying direction may be increased within a predetermined conveying speed (such as a speed at which the container C can be artificially placed on the carrier 9), but a higher conveying speed is required. In this case, it is preferable to increase the number of placements in the direction perpendicular to the transport direction rather than the number of placements in the transport direction. As a matter of course, when the number of devices arranged in the direction perpendicular to the transfer direction is increased, the number of transfer rows is increased accordingly, and the number of devices that can be placed on the carrier 9 is also increased. That is, when a plurality of processing heads are arranged in the direction perpendicular to the conveyance direction, the articles are conveyed in parallel in the same number of columns as the number of arranged processing heads.

In the above-described embodiment, the second processing time (filling processing time) is an integral multiple of the first processing time (capping processing time), but it does not have to be an integral multiple. For example, the filling processing time may be 6 seconds and the capping processing time may be 4 seconds. In this case, if the number of capping heads 51 is two, the number of filling heads 31 is 2×1.5=3. However, in the case of two-line transport as in the above-described embodiment, it is preferable that the number of processing heads be a multiple of the number of transport lines. Therefore, the number of filling heads 31 is preferably six, which is the lowest common multiple of three and two. At this time, the number of capping heads 51 is 6/1.5=4.

As described above, in the article conveying and processing apparatus according to the present invention, even if the first processing time and the second processing time are different, the number of the first processing heads and the number of the second processing heads can be appropriately set. Therefore, synchronization can be easily established between the first processing section and the second processing section.
