Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is a container that is transported on a conveyor after separating the sachets individually from a sachet belt in which a large number of sachets containing contents such as liquid and powdered fluid are connected in a long shape, etc. The present invention relates to an apparatus for distributing to a predetermined distribution target section.
[0002]
[Prior art]
In the container containing the main body, the sachet containing the additional product is stored as a subsequent process. For example, after storing natto in a container, an appropriate film is laid, and one or more sachets containing an additive such as sauce or hot pepper are stored thereon. The same thing is often performed when packaging various kinds of instant foods such as instant ramen, not limited to natto containers.
[0003]
Such sachets are usually manufactured as a sachet strip connected in a long shape at a separate factory, and the sachets are carried into a container stuffing factory for food or the like. In a food container filling factory, a plurality of sachets connected in a strip shape are separated one by one and then distributed to individual containers or the like.
[0004]
Conventionally, several proposals have been made as distribution devices for this purpose. For example, Patent Document 1 describes an apparatus as shown in FIG. This apparatus uses a sachet band A in which a number of sachets a containing contents are connected in a long shape, a delivery device 50 that sequentially feeds the sachets, and a transport having a transport surface that runs in the delivery direction of the delivery device 50. The cutting device 30 located between the conveyor 81 and the delivery apparatus 50 and the conveyance conveyor 81 is provided. When one sachet a is delivered from the delivery device 50, the cutting device 30 operates in synchronization with it, and the sachet a is cut and separated from the subsequent sachet group connected thereto. The separated sachets a are conveyed leftward in the figure by the conveyor 81. By repeating this process, a predetermined number (four in the figure) of sachets a are provided on the conveying surface of the conveyor 81 at predetermined intervals. Be placed. Above the transport conveyor 81, a plurality of (four in the figure) suction pads 20 are arranged at predetermined intervals so as to be able to move up and down and back and forth. The sachets a are vacuum-adsorbed and then moved onto a dispensing object 60 (for example, a natto container) located in the front, where the vacuum is broken to distribute the four sachets a into each container. ing.
[0005]
In the above apparatus, the individually cut sachets are sequentially sent to a position facing the suction pad by the transport conveyor, and positioning of the sachets on the transport conveyor (each sachet with the same interval as each suction pad) To be positioned on the conveyor, to make the center of each suction bat coincide with the center of each pouch, etc.). If the positioning becomes unstable, there will be inconveniences such as mistakes in suction, omission leakage, or dropping of a part of the sachet protruding from the container, and the operation of the apparatus must be stopped.
[0006]
As another distribution device, as shown in FIG. 6, as shown in FIG. 6, the suction pad 20 and the cutting device 30 are located on the delivery side of the delivery device 50, and the suction pad 20 holds the delivered small bag a. In the adsorbed state, the adsorbed sachet a is cut with the subsequent sachet connected thereto, and after the severing, the suction pad 20 is further lowered to break the vacuum on the container 60, and the sachet a is put into the container 60. A dispensing device is disclosed which is adapted to be placed in the inside. In this apparatus, the delivered sachet is directly adsorbed by the suction pad, and after being cut, it is distributed as it is in the container, so that there is little misalignment at the time of adsorption, and the insertion into the container is ensured.

[Problems to be solved by the invention]
In recent years, there has been a demand for speeding up the operation of dispensing pouches using this type of dispensing device. The dispensing device described in Patent Document 2 (Japanese Patent Publication No. 7-112852) has a configuration in which one suction pad is arranged in one delivery device, and the suction pad moves up and down each time suction is performed. Need to be distributed. Therefore, the working speed is naturally limited. With a plurality of sachets sent out, a plurality of sachets are sucked and cut simultaneously using a plurality of suction pads and a plurality of cutting devices. Although it is possible to distribute the sachets simultaneously, it is actually not easy to assemble and arrange a plurality of suction pads and a plurality of cutting devices in the device so that suction and cutting can be reliably performed. In addition, it is actually not easy to reliably adsorb a plurality of delivered sachets simultaneously. For this reason, improvement is still necessary to perform a quick and accurate distribution operation.
[0009]
DISCLOSURE OF THE INVENTION The present invention has been made in view of the circumstances as described above, and the distribution of sachets that can simultaneously and quickly distribute the sachets delivered from the delivery device to the plurality of containers that are the distribution objectives. An object is to provide an apparatus.
[0010]
[Means for Solving the Problems]
A sachet dispensing device according to the present invention includes a delivery device for delivering a sachet band in which a plurality of sachets containing contents are connected in a long shape, an adsorption pad for adsorbing the delivered sachet, and an adsorption pad there in a pouch which has been adsorbed and a cutting device for cutting between the subsequent pouch connected thereto, in dispensing device of pouch which is adapted to the cut pouch distributing the distribution desired product by the movement of the suction pad A plurality of suction pads are mounted on a support frame that is movable in a transverse direction perpendicular to the delivery direction of the delivery device, and suction by the suction pad of the sachet delivered from the delivery device and subsequent cutting from the sachet. by repeating the feed required number of cycles of movement of the feed in the lateral direction orthogonal to the direction of the device of the support frame after cutting and cutting by the device, Being adapted pouch is individually separated in the suction pad of a main number is adsorbed, moves the supporting frame in a state of sucking the pouch to dispense object portion is on the distribution target product, where vacuum suction pads The sachet is broken and the sachets adsorbed on the respective suction pads can be distributed to distribution objects.
[0011]
In the above apparatus, the sachet delivered from the delivery device is vacuum-sucked by the first (first) suction pad immediately after delivery, and is cut by the cutting device in that state to be separated from the subsequent sachet group. While the next sachet is delivered, the support frame moves in the lateral direction perpendicular to the delivery direction of the delivery device by a predetermined distance (the distance that the next suction pad reaches the delivery port of the delivery device ), and one cycle is completed. To do. After the lateral movement, the next (second) suction pad sucks the second sachet sent out. In this state, the second sachet is cut and separated from the subsequent sachet group. In the process of sucking and cutting the second sachet, the first suction posture remains as it is without any external force acting on the previously cut sachet (the sachet sucked on the first suction pad). Maintained. Thereafter, this cycle is repeated as many times as necessary, as many times as the number of suction pads attached to the support frame.
[0012]
After the sachets are adsorbed to the required number of suction pads, the support frame is moved to the distribution target part on the distribution object (for example, the same number of natto containers) , and each adsorption is placed above the distribution object. Position the pad. When the vacuum of the suction pad is broken in this state, each sachet is distributed in the distribution object while maintaining the posture of being sucked by the suction pad.
[0013]
As described above, in the device according to the present invention, since the sachets coming out from the delivery device are directly adsorbed individually by the plurality of adsorbing pads attached to the support frame, the posture at the time of adsorbing is the same, and an adsorption error may occur Sex is very small. On the other hand, since the cutting with the succeeding sachet group is performed by one cutting device, the overall configuration is simplified. Since the plurality of sachets adsorbed by the plurality of suction pads can be simultaneously distributed to a plurality of containers by a single movement of the support frame, high working efficiency can be obtained.
[0014]
The movement of the dispensing object is an intermittent movement synchronized with the dispensing cycle (that is, the movement is stopped when the support frame moves over the dispensing object , and in that state the suction pad vacuum is broken and the sachet is removed. distributed to the distribution target product, then moved by a predetermined distance, such as preparing for the next dispensing cycle, it may be a mobile and the mobile mode to repeat stop). However, the intermittent movement mode is not always optimal for speeding up the work. Therefore, in a preferred embodiment of the apparatus of the present invention, the support frame can be moved at a speed synchronized with the moving speed of the distribution object, and the support frame is adsorbed while moving at a speed synchronized with the distribution object. and it is capable of distributing the pouch adsorbed to destroy the vacuum of the pad to the suction pad to the distribution target. In this aspect, a plurality of cycles can be continuously performed without stopping the movement of the target distribution, and the work efficiency can be greatly improved.
[0015]
In the apparatus according to the present invention, one apparatus may be formed by arranging one support frame corresponding to one delivery apparatus. In this case, for example, one kind of sachet is distributed to a distribution object which is a container. It may be required to distribute two or more sachets in one container. In order to meet the demand, in the preferred embodiment of the apparatus according to the present invention, two or more sets of the delivery device and the corresponding support frame are arranged. In the same manner as described above, after the sachets are adsorbed to the suction pads attached to the respective support frames, each support frame is moved so that the respective suction pads are close to each other and aligned, and then the distribution object. The vacuum on the suction pad of each support frame is simultaneously broken. Thereby, it is possible to simultaneously dispense two or more pouches in the same distribution target site in the distribution target product, it is possible to further expedite the work. For example, when the distribution target compound of natto containers can be distributed sauce pouch and Tsurashi pouch and at the same time in a single container (distribution target site).
[0016]
In the present invention, the type and shape of the distribution target section are not particularly limited and are arbitrary. Preferably, it is a container group that is continuously transferred at a predetermined interval on the conveyor, and as described above, each container constituting the container group constitutes a distribution target place. Distance of the suction pad mounted to the spacing between the support frame of each container constituting the container group is the same. Although not limited, a container is a natto container, a cup noodle, a tofu container, etc., for example, The articles | goods put in a small bag are sauce, spicy, dried leek, dried corn, etc., for example.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described by way of embodiments with reference to the drawings. FIG. 1 is a side view showing a main part of a distributor according to the present invention, FIG. 2 is a front view, and FIG. 3 is a top view. FIG. 4 is a conceptual diagram for explaining a part of the operation of the apparatus.
[0018]
The distribution device 1 includes a sachet adsorbing portion 10 that is movable in the three axial directions on the frame 2 and a delivery device 50 that sends out the sachets toward the sachet adsorbing portion 10. The sachet adsorbing portion 10 has a frame body 11, and the frame body 11 is reciprocated by a required distance in the left-right direction (X-axis direction) by means such as a feed chain 4 with respect to the horizontal frame 3 of the frame 2. Has been. The frame 11 is provided with a Y-axis actuator 12 in the vertical direction (Y-axis direction), and a Z-axis actuator 13 in the front-rear direction (Z-axis direction) is provided at the upper end of the Y-axis actuator 12. A horizontal support frame 14 is provided at the front end (right side in FIG. 1) of the Z-axis actuator 13, and the support frame 14 has a first support frame 15 and a second support frame 16 having an L-shaped cross section. Are attached in the X-axis direction. The first support frame 15 and the second support frame 16 have the same shape, and in this example, as can be seen from FIG. 3, there is a slight gap in the X-axis direction, as can be seen from FIG. In addition, they are arranged at a slight distance in the Z-axis direction. Further, the first support frame 15 and the second support frame 16 can be moved in the X-axis direction along the guide rails 17 and 18, respectively. The movement is performed as a movement independent of the support frame 14 by driving means such as the chain 19.
[0019]
The horizontal piece portion of the first support frame 15 is provided with a plurality of (six in the illustrated example) suction pads 20a with a predetermined interval via an appropriate attachment member 21a. Each suction pad 20a can be moved slightly in the Z-axis direction and the Y-axis direction by an appropriate actuator provided on the mounting member 21a. The second support frame 16 is a position where the two support frames do not collide with each other when the two support frames move relative to each other in the X-axis direction along the guide rails 17 and 18 (the position above the first support frame 15 in the figure). As in the first support frame 15, a plurality of (six in the illustrated example) suction pads 20b are provided on the horizontal piece portion via the Z-axis direction and the Y-axis. It is mounted so that it can move slightly in the axial direction.
[0020]
The spacing between the suction pads 20b and 20b is the same as the spacing between the suction pads 20a and 20a, and as shown in FIG. 1, when the suction pad 20a and the suction pad 20b are viewed from the side, They are attached to the first support frame 15 and the second support frame 16 so that they are in close proximity and their lower end levels are substantially the same level. The structure of the suction pad and the mechanism for the suction and vacuum break may be the same as those used in the conventional distributor described with reference to FIG. 5 or FIG. 6, and detailed description thereof is omitted.
[0021]
In the present invention, the sachet delivery device 50 may be the same as that used in the above-described conventional dispensing device. Therefore, the detailed description is abbreviate | omitted. In the illustrated example, one sachet delivery device 50 is attached to the first support frame 15 (50a), and one sachet delivery device 50 is attached to the second support frame 16 (50b). As shown in FIG. 3, when the support frames 15 and 16 are at the leftmost rest position, the mounting positions are opposite to the suction pads 20a and 20b located on the most distal side (right side in the figure). It is assumed to be a position. The sachet delivery direction of the sachet delivery devices 50a and 50b is a direction (Z-axis direction) orthogonal to the movement direction (X-axis direction) of the support frames 15 and 16. And between the delivery part and the suction pads 20a, 20b, as in the case of the conventional example shown in FIG. 6, the small bag a sucked by the suction pad is cut between the subsequent small bags connected to it. Cutting devices 30 and 30 are provided.
[0022]
The operation of the device 1 will be described. At the start of operation, the feed chain 4 is controlled so that the two support frames 15 and 16 are at their leftmost positions shown in FIGS. The actuators 12 and 13 are controlled so that the lower end positions of the suction pads 20a and 20b are close to the small bag delivery portions of the small bag delivery devices 50a and 50b. The pouch delivery devices 50a and 50b are operated to deliver the pouch. Thereby, one small bag is sent out to just under the suction pad 20a and the suction pad 20b.
[0023]
At that position, the suction pads 20a and 20b are lowered to suck the sachets. In FIG. 1, reference numeral 31 denotes a support plate that is positioned below the sachet to be sent out in order to stabilize the suction, and is arranged as necessary. The cutting devices 30 and 30 are operated in conjunction with the suction of the suction pads, and the sachets vacuum-sucked by the first suction pads 20a and 20b are cut from the subsequent sachet group while maintaining the posture. Simultaneously with the end of cutting, the support frames 15 and 16 move to the right in the drawing so that the second suction pads 20a and 20b from the right face the small bag delivery devices 50a and 50b. This completes one cycle.
[0024]
During the lateral movement in the right direction, the next sachet is delivered from the sachet delivery devices 50a and 50b, and the second suction pads 20a and 20b suction the second sachet in the same manner. In this state, the second sachet is cut and separated from the subsequent sachet group. Thereafter, this cycle is repeated as many times as necessary (six times in the illustrated case), and the sachets are sucked onto all the suction pads 20a and 20b attached to the support frames 15 and 16 (in some cases, two to five). The sachets may be sucked by any number of suction pads 20a, 20b between the two).
[0025]
After adsorbing the required number of sachets, the necessary actuators are operated to pull the support frames 15 and 16 rearward in the Z-axis direction (left side in FIG. 1) (indicated by P1 in FIG. 1). At the same time, the first support frame 15 and the second support frame 16 are moved relatively independently of the support frame 14 by moving the chain 19 and the like so that the two support frames 15 and 16 are moved in the front-rear direction. Overlapping state. Thereby, as schematically shown in FIG. 4, two of the six actuators are positioned to face each other. 4A is a top view schematically showing the state, and FIG. 4B is a side view. In FIG. 4, reference numeral 60 denotes a plurality of container groups as target distributions and a conveyor 61 for transferring them. The individual containers in the plurality of container groups serve as “distribution target locations” in the present invention.
[0026]
As shown in FIG. 1, the container transport means 65 provided with the conveyor 61 is a conveyor just below the position (position indicated by P1) where the support frames 15 and 16 are pulled rearward in the Z-axis direction (left side in FIG. 1). 61 is positioned. After the support frames 15 and 16 are pulled, an appropriate actuator is operated to lower the suction pads 20a and 20b slightly above the numerous containers 60 conveyed on the conveyor 61 (indicated by P2 in FIG. 1). At that position, the vacuum of the suction pads 20a and 20b is broken. Thereby, each sachet a is distributed in the container 60 while maintaining the posture of being sucked by the suction pad.
[0027]
The movement of the conveyor 61 is stopped when the support frames 15 and 16 are moved onto the container 60. In this state, the suction pads 20a and 20b are lowered and the vacuum is broken to distribute the sachets. During the adsorption cycle of the support frames 15 and 16, the movement may be intermittent, such that the frame moves by a predetermined distance to prepare for the next distribution cycle. For the purpose of speeding up the work, the conveyor 61 may be continuously moved so that the support frames 15 and 16 can be moved at a speed synchronized with the moving speed of the conveyor 61 during the distribution cycle. At that time, when the support frames 15 and 16 are moved onto the container 60, the movement in the same direction synchronized with the movement of the conveyor 61 is started, and the suction pads 20a and 20b are lowered while moving synchronously. Vacuum breaks and sachets are dispensed. Note that the above-described movement mode can be easily implemented by using a conventionally known control mechanism such as feedback control that receives a pulse signal from an encoder disposed on a conveyor. Depending on the case, it is good also as a mechanism which can employ | adopt both selectively. After completing the required distribution work according to any aspect, the support frames 15 and 16 and the suction pads 20a and 20b are returned to the initial positions, and thereafter the same operation is repeated as many times as necessary to thereby perform the required operation by the apparatus of the present invention. The sachet dispensing operation ends.
[0028]
In the above description, the state in which the two support frames 15 and 16 are simultaneously operated has been described. However, only one support frame can be operated, and the other support frame can be inactive to perform the distribution work. . Three or more support frames may be operated simultaneously. It is also possible to assemble the dispensing device with only one support frame.
[0029]
【The invention's effect】
As described above, in the apparatus of the present invention, the sachets coming out from the delivery apparatus are directly adsorbed individually by the plurality of adsorbing pads attached to the support frame. The possibility is very small. On the other hand, since the cut | disconnection of the adsorbed sachet and the succeeding sachet group is performed by one cutting device, the overall configuration is simplified. Further, since the plurality of sachets adsorbed by the plurality of suction pads can be simultaneously distributed to a plurality of containers by a single movement of the support frame, high working efficiency can be obtained.
