Description

The present invention relates to a combination weighing device, and more particularly to a combination weighing device suitable for weighing a relatively soft and elongated article.

As a combination weighing device for an elongated rod-shaped article, for example, there is a device described in Patent Document 1. In the device of Patent Document 1, a rod-shaped article that has been combined and weighed is guided to a collecting chute formed in a vertically constricted vertical cylinder through a collecting funnel, and then supplied to a swing guide cylinder and a guide cylinder. .. The supplied rod-shaped article is housed and held in a vertical posture with the swing guide cylinder and the guide cylinder inserted, and the swing guide cylinder is swung to eliminate the overlap of the articles.

Patent Document 1 targets a combination of hard rod-shaped articles that do not bend or break due to a slight impact. For example, cheese is sandwiched between dry sheets made from ground cod meat as a main ingredient. It is difficult to apply to relatively soft and elongated articles such as cheese cod or jerky cut into strips. That is, when an attempt is made to weigh a relatively soft and elongated article with the device of Patent Document 1, when the article is dropped and accommodated in the guide cylinder at the final stage in a vertical posture, the article may be bent or broken due to the drop impact. is there. For this reason, it is difficult to suitably discharge the weighed articles in an aligned state.

In particular, foods such as cheese cod are often sold in a transparent packaging bag or the like that can be seen from the outside, and if they are mixed with bent or broken foods, the commercial value will drop.

Further, Patent Document 2 also targets a hard rod-shaped article such as a stick pan, and it is difficult to align and discharge a relatively soft and elongated article. That is, a slender article that is relatively soft, moist, and has a large slip resistance, such as a cheese cod, is aligned and changed in posture while sliding down along an array chute having a throat that extends downward while narrowing. Is difficult.

For this reason, conventionally, weighing and packaging of soft elongated articles such as cheese cod has been performed manually. Specifically, the operator manually arranges, aligns, and packages the articles on the tray, weighs them with a platform scale, and then loads or inserts them into the packaging material to seal the packaging material. I'm going at.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a combination weighing device capable of weighing relatively soft and elongated articles and carrying them out in an aligned state. ..

In order to achieve the above object, the present invention is configured as follows.

The combination scale vibrates and transports the articles to the measuring unit. It has an alignment supply unit that aligns and supplies to.

According to the present invention, the elongated articles are aligned and fed to the weighing unit while being oscillated by the alignment feeder. The articles discharged from the plurality of measuring units selected by the combination calculation are conveyed by the transport unit and sent to the well-ordered unit without significantly breaking the alignment state. The articles sent to the assembly alignment unit are assembled here and vibrated again to be aligned.

In this way, the articles supplied to the measuring unit are aligned by the vibration action of the alignment supply section, and the articles discharged from the weighing unit are subjected to the vibration action again at the well-ordering section to be aligned. For example, even relatively soft and elongated articles such as cheese cod and jerky can be collectively aligned and carried out to a subsequent packaging processing step or the like without being bent or broken.

(2) In a preferred embodiment of the present invention, the alignment supply unit of the combination scale has a transport trough that vibrates and transports the article to the measuring unit, and the transport surface of the transport trough is the transport direction of the article.

It has a well-shaped collective trough with a U-shaped cross section into which articles to be carried out from the above are loaded, and a vibration exciter that vibrates the collective trough.

Here, the U-shape means a shape having a recessed and curved portion, and the curvature of the curved portion is arbitrary.

According to this embodiment, the article discharged from the measuring unit is conveyed by the transport conveyor along the one direction which is the arrangement direction of the plurality of measuring units and is charged into the collecting trough. The loaded articles are laminated and assembled along the cross-sectional shape in a U-shaped cross-sectional collecting trough, and are aligned by being subjected to the vibration action of the vibrator.

(4) In still another embodiment of the present invention, the alignment supply unit of the combination scale has a plurality of the transport troughs that can be individually vibration-driven, and the plurality of transport troughs are used in the transport direction of the article. It is placed along.

According to this embodiment, by driving a plurality of transport troughs with different arbitrary vibration amplitudes and vibration times, it is possible to sequentially arrange the alignment state of the articles for each transport trough and adjust the transport amount of the articles. It becomes possible.

(5) In another embodiment of the present invention, the alignment supply unit of the combination scale is a transport trough shutter that opens and closes the transport path of the transport trough on the lowermost side in the transport direction among the plurality of transport troughs. The transport trough shutter is provided at the end of the transport trough on the lowermost side.

It is aligned and held in a posture orthogonal to. The aligned and held articles are supplied to the weighing unit in the aligned position by opening the transport trough shutter.

(6) In still another embodiment of the present invention, the gathering alignment portion is from a shutter for gathering trough that opens and closes an open end on one side of the gathering trough in the longitudinal direction and from the other side of the gathering trough in the longitudinal direction. It has a pusher capable of moving back and forth in the collective trough and pressing the article.

According to this embodiment, after the article is fed into the collective trough, the pusher at the retracted position is moved forward toward the shutter side for the collective trough that closes the open end of the collective trough, thereby being vibrated. The rear end of the article, which is easy to move, can be lightly pressed to smoothly align the rear end.

Further, by moving the pusher to advance greatly in conjunction with the opening of the shutter for collecting trough, it is possible to discharge the collected and aligned articles at once without breaking the alignment state.

(7) In another embodiment of the present invention, the transfer unit has a plurality of the transfer conveyors, the assembly alignment unit has a plurality of the collection troughs, and the plurality of transfer conveyors are parallel to each other. And, it is possible to move to a receiving position for receiving the article discharged from the measuring unit and a retracting position deviating from the receiving position, and each of the plurality of collecting troughs is such that the transport conveyor moves to the receiving position or the retracting position. When they are in the position, they are arranged at the positions where the articles carried out from the conveyor are put in.

FIG. 1 is a perspective view of a combination weighing device according to an embodiment of the present invention, FIG. 2 is a schematic front view schematically showing the combination weighing device of FIG. 1, and FIG. 3 is a combination of FIG. It is a schematic side view which shows typically the weighing device.

In the following, for convenience of explanation, the left-right direction in FIG. 2 and the front-back direction of the paper surface in FIG. 3 are referred to as the left-right direction, and the front-back direction of the paper surface in FIG. 2 and the left-right direction in FIG. 3 are referred to as the front-back direction. I will do it.

The combination weighing device of this embodiment is used for weighing and carrying out relatively soft and elongated articles such as cheese cod or jerky, which is cut into strips by sandwiching cheese between dry sheets made from minced fish paste as a main ingredient. It is a suitable combination weighing device. This combination weighing device conveys the combination scale 1 that combines and weighs and discharges articles such as cheese cod, and the articles discharged from the combination scale 1 to one side (left in this example), and collectively aligns them. It is equipped with a well-ordered unloading device 2 for unloading.

The combination scale 1 arranged at the upper part includes a number of systems in which articles are arranged in parallel in the left-right direction, in this example, an alignment supply unit 3 for aligning articles while transporting them forward along a 14-system alignment transfer path, and each of the alignment supply units 3. It is provided with a multi-unit (14 stations in this example) weighing units 4 arranged side by side in one direction, in this example, along the lateral direction, so as to receive the articles transported from the aligned transport path.

One aligned transport path in the aligned supply unit 3 is configured by vertically arranging three straight feeders 5 in a staircase pattern that descends forward along the transport direction of the article. The articles transported in each aligned transport route are supplied to the corresponding measuring units 4, respectively.

Each measuring unit 4 receives a supply hopper 6 that receives and temporarily holds the articles conveyed in each alignment transport path in the alignment supply unit 3, and an article w discharged from the supply hopper 6 and measures the weight thereof. It is equipped with a hopper 7. In this embodiment, the hoppers 6 and 7 are not shown, but are embossed in order to reduce friction with the article.

In the combination scale 1, the combination measurement is performed in the same manner as in the conventional case. That is, in the control device (not shown) of the combination scale 1, the combination weight in which the weights of the articles weighed by the plurality of measuring hoppers 7 are variously combined is equal to the target combination weight or the predetermined weight closest to the target combination weight. A combination calculation is performed to select an appropriate amount combination that is a combination of the weighing hoppers 7 that are in the range. The article w of the weighing hopper 7 selected as an appropriate amount combination in this combination calculation is discharged downward.

As shown in FIG. 3, the measuring hopper 7 is provided with a pair of front and rear gates 7a and 7b that independently open and close in opposite directions. By selecting and opening one of the gates 7a and 7b, 7a (7b), the held article can be discharged along the two front and rear routes.

4 to 7 are views showing the structure of the straight feeder 5 constituting the alignment supply unit 3. Of the three straight feeders 5, the upper and middle straight feeders 5 have the same structure. Therefore, FIGS. 4 to 6 show the upper straight feeder 5 as a representative. Further, in FIGS. 6 and 7 and FIG. 9 described later, only one article w is typically shown.

FIG. 4 is a vertical sectional side view showing the upper straight feeder 5, which is the best side in the transport direction of the article, FIG. 5 is an enlarged vertical sectional side view of the end portion in the transport direction, and FIG. It is the perspective view. FIG. 7 is a perspective view of the lower straight feeder 5 which is the lowermost side in the article transporting direction among the three straight feeders 5.

Each of the straight-moving feeders 5 in each stage has a structure in which a transport trough 10 in which a pair of side plates are erected from both ends in the width direction of the bottom plate and a connecting plate 11 on the lower surface of the bottom plate of the transport trough 10 are provided. ing. As shown in FIG. 4, the connecting plate 11 is positioned and locked to the vibration head portion 12a of the exciter 12, and is detachably connected by a buckle-shaped fastener 13.

Further, the bottom surface 10a, which is the transport surface of the transport trough 10, is formed in a continuous corrugated shape having a pitch of, for example, about 15 mm and a depth of, for example, about 2 mm in the transport direction (front-back direction) of the article w. The corrugated pitch of the bottom surface 10a is a pitch corresponding to the width of one article w so that one article w enters the corrugated recess and is oriented sideways.

The elongated article w placed on the bottom surface 10a of the transport trough 10 is vibrated so as to be aligned in a lateral posture along the wavy shape, that is, a posture in which the longitudinal direction thereof is orthogonal to the transport direction of the article w. , It is designed to be vibrated forward. That is, the elongated article w is vibrated and transported by the transport trough 10, and is aligned in a lateral posture along the corrugated shape by repeatedly passing through the corrugated concave portions and convex portions that are continuous at a constant pitch in the transport direction. Be transported.

Since the transport direction of the article w by the transport trough 10 is forward and the arrangement direction of the plurality of measuring units 4 is the lateral direction, the direction orthogonal to the transport direction of the article w is the arrangement direction of the plurality of weighing units 4. It becomes a certain horizontal direction. Therefore, the transport trough 10 vibrates and transports the article w while its longitudinal direction is aligned in the lateral direction, which is the arrangement direction of the plurality of measuring units 4.

The transport trough 10 in the upper and middle straight feeders 5 is provided with a movement restraining plate 14 that suppresses the transport movement of articles while the tip end side of the bottom surface 10a is inclined forward. The movement restraining plate 14 is made of a wide flat plate material capable of stably placing the article w in a sideways posture. The movement restraining plate 14 extends horizontally from the bottom surface 10a of the transport trough 10 in the transport direction, and is provided with an inclined rising portion 14a at the tip thereof, which is slightly upright and inclined upward.

Therefore, the article w that has been vibrated and conveyed on the corrugated bottom surface 10a is pushed onto the movement suppression plate 14, and then pushed by the subsequent article w to move on the movement suppression plate 14, and the end portion is inclined and rises. The movement is suppressed in the portion 14a, and the article is carried out little by little over the inclined rising portion 14a by the subsequent extrusion transportation. In this way, the movement restraining plate 14 imparts an appropriate transport resistance to the article w in the sideways posture, and suppresses the posture from being collapsed due to a large amount of the article w being sent out at once from the end of the trough. In addition, by giving a transport resistance to the article immediately before it is carried out, there is also an effect of adjusting the posture of the article which is insufficiently aligned.

The movement suppressing plate 14 is not limited to a flat plate shape, but may be a comb-teeth shape or the like.

As shown in FIG. 7, a transport trough shutter 15 that can be swung up and opened around the upper fulcrum p is provided at the tip of the transport trough 10 in the lower straight feeder 5, which is the final stage. The transport trough shutter 15 opens and closes the end of the transport path by the transport trough 10 by the air cylinder 16.

In this embodiment, elongated articles are collectively supplied to the transport trough 10 of the upper straight feeder 5 by using a robot hand or the like (not shown). The articles supplied to the upper straight feeder 5 are vibrated and conveyed to the middle straight feeder 5 and the lower straight feeder 5 in order of vibration and are aligned laterally.

In this embodiment, the vibration amplitude of the upper straight feeder 5 to which the articles are collectively supplied is the largest and the vibration time is the shortest, and the vibration amplitude of the lower straight feeder 5 is the smallest and the vibration time is the longest. There is.

As a result, the articles supplied in the state of being gathered in the upper straight feeder 5 are vibrated and conveyed to the middle straight feeder 5 and the lower straight feeder 5 in an appropriate amount in order, and the articles are separated in the lower straight feeder 5. The article w can be arranged sideways so as to enter the corrugated recess of the bottom surface 10a of the transport trough 10.

The drive of each straight feeder 5 is started when the article is discharged from the supply hopper 6 and the supply hopper 6 is emptied.

The step between the upper straight feeder 5 and the middle straight feeder 5 and the step between the middle straight feeder 5 and the lower straight feeder 5 are when the article falls and is transferred to the next straight feeder 5. In addition, a small size is preferable in order to prevent the alignment state from being disrupted.

The corrugated shape of the bottom surface 10a of the transport trough 10 may be, for example, a sine corrugated corrugated shape, or a serrated corrugated shape with a steeply inclined rising surface directed in the transport direction. ..

As shown in FIGS. 1 to 3, the well-ordered unloading device 2 below the combination scale 1 receives the articles w discharged from the plurality of measuring hoppers 7 of the combination scale 1 and arranges the plurality of measuring units 4 in the arrangement direction. The conveyor 21 is provided as a conveyor unit for transporting along the lateral direction. In this example, two transport conveyors 21 for transporting the article w to the left are provided in the front-rear direction as shown by the solid line in FIG. 3, and each transport conveyor 21 is composed of a belt conveyor.

Further, the well-ordering and unloading device 2 constitutes a well-ordering unit 40 that collects and aligns the articles w discharged from the conveyor 21 on the lower side of the conveyor 21 in the transport direction, as shown in FIG. It is equipped with a well-order trough 25, a vibration exciter 26, and the like.

Each conveyor 21 is supported so as to be movable back and forth along the guide rail 22 shown in FIG. 1, and is individually moved back and forth with a predetermined stroke by an actuator 23 such as an air cylinder.

As shown in FIG. 3, the rearward moving position of the transport conveyor 21 on the front side (right side in FIG. 3) is the receiving position (a) of the article facing the discharge path forward of the measuring hopper 7. Further, the forward moving position of the conveyor 21 on the rear side (left side in FIG. 3) is the receiving position (a) of the article facing the discharge path to the rear of the measuring hopper 7.

A pair of front and rear guides 24 along the conveyor path are erected on both sides of each conveyor 21 in the width direction. These guides 24 guide the article w discharged from the measuring hopper 7 onto the belt without spilling.

On the lower side of the conveyor 21 in the transport direction, a plurality of collective troughs 25 into which the articles w discharged from each conveyor 21 are charged are arranged.

As shown in FIG. 3, each collective trough 25 is located at a receiving position (a) at which each transport conveyor 21 receives the articles discharged from the measuring hopper 7 and at a retracting position (b) away from the receiving position (a). Four are provided in a line in the front and rear so as to face the end of each conveyor 21 at the time.

Therefore, the articles discharged from the measuring hopper 7 of the combination scale 1 are conveyed by the two conveyors 21 at the receiving position (a) or the retracting position (b), and the four collecting troughs are carried along the four conveyor routes. It is put into each of 25.

The conveyor 21 is driven for a certain period of time when the article is loaded into the collecting trough 25.

FIG. 8 is a vertical cross-sectional view of a well-ordering unit 40 for collecting and aligning articles carried out from a transport conveyor 21, FIG. 9 is a perspective view of a collecting trough 25 of the well-ordering unit 40, and FIG. 10 is a set. It is a front view of the trough 25.

The collective trough 25 constituting the collective alignment portion 40 has a recessed and curved bottom of the lower constriction, and the trough body 25a having a U-shaped cross section with an open upper part is surrounded by a support plate 25b to be reinforced and supported. It has a structure. In this embodiment, the trough body 25a is embossed, although not shown, in order to reduce friction with the article.

The support plate 25b has a structure in which a pair of side plates are erected from both ends in the width direction of the bottom plate. The connecting base 25c connected to the lower surface of the support plate 25b is positioned and locked to the vibration head portion 26a of the exciter 26, and is detachably connected by the buckle-shaped fastener 27.

At the tip of the collective trough 25 in the transport direction, vertically oriented rail portions 28 connected to the support plate 25b are arranged so as to face each other inward. A shutter 29 for collecting troughs is guided and supported on the opposing rail portions 28 so as to be vertically movable. As shown in FIG. 8, the collective trough shutter 29 is connected to an air cylinder 30 fixedly arranged in a vertical position above the trough via a stay 31. The collective trough shutter 29 opens and closes the transport path in the collective trough 25. The collective trough shutter 29 can receive the tip of the article w loaded from the conveyor 21.

The gathered articles w are aligned and aligned by the vibration transporting action of the collecting trough 25 and the blocking action of the collecting trough shutter 29.

Further, a pusher 33 that can move forward and backward in the longitudinal direction of the trough by an air cylinder 32 is provided on the inner back portion of each collective trough 25.

Next, the operation of the combination weighing device configured as described above will be described.

An elongated article w is timely supplied to the starting end of the upper straight feeder 5 in the alignment supply unit 3 in the transport direction by using a robot hand or the like (not shown).

The article w supplied to the start end of the straight-moving feeder 5 in the upper stage first receives the vibration-carrying action of the straight-moving feeder 5, and moves forward while being aligned in a posture along the corrugated shape of the bottom surface 10a of the transport trough 10, that is, in a lateral posture. Will be sent to. The article w that has reached the end of the transport trough 10 of the upper straight feeder 5 is transferred to the middle straight feeder 5 over the movement restraining plate 14 while maintaining the sideways posture. Similarly, the straight-moving feeder 5 in the middle stage is also sent forward while being aligned in a lateral posture along the corrugated shape of the bottom surface 10a of the transport trough 10, and is sent to the straight-ahead feeder 5 in the lower stage.

In the lower straight feeder 5, the feeder 5 is sent forward while being aligned in the sideways posture, and is received and held by the transport trough shutter 15.

When the supply hopper 6 in the measuring unit 4 is emptied, the transport trough shutter 15 is open-controlled for a predetermined time, and a small amount of articles are supplied to the supply hopper 6 in a sideways posture. Then, when the article w is discharged from the weighing hopper 7 which is weighed by the weighing hopper 7 and selected as an appropriate amount combination by the combination calculation and becomes empty, the supply hopper 6 is opened and a new article w is supplied to the weighing hopper 7. To.

One of the gates 7a and 7b 7a (7b) in the plurality of weighing hoppers 7 selected for the appropriate amount combination in the predetermined weight range by the combination calculation is selectively opened and controlled, and the article w in the predetermined weight range is moved forward or. It is dropped and discharged to the rear discharge path. The aligned state of the plurality of articles w that are dropped and discharged from the measuring hopper 7 is not significantly broken, and the articles are dropped and discharged in a substantially sideways posture.

When the article is dropped and discharged from the measuring hopper 7, at least one of the transport conveyors 21 on the front side and the rear side, which is the discharge path of the article from the measuring hopper 7, is moved to the receiving position (a) of the article. exist. The article w discharged from the measuring hopper 7 is dropped and supplied to a plurality of places in the transport direction of the conveyor 21 at the receiving position (a) in a lateral posture in which the longitudinal direction of the article is substantially along the transport direction of the conveyor 21. Will be done.

The transport conveyor 21 that has received the article w selects either the receiving position (a) or the retracting position (b) as the carrying-out position of the article according to the situation of the collecting trough 25, and moves back and forth for each transport conveyor 21. Conveying is performed toward the collective trough 25 arranged corresponding to the carry-out position of the two systems. The entire amount of the article w discharged from the measuring hopper 7 and dropped and supplied to a plurality of places in the transport direction of the conveyor 21 is put into the collective trough 25, so that the article w in a predetermined weight range is carried into the collective trough 25. Be housed.

Basically, the discharge of articles in a predetermined weight range from the measuring hopper 7 is alternately performed on the front conveyor 21 and the rear conveyor 21. Further, each transport conveyor 21 basically alternately carries out the articles in the predetermined weight range with respect to the collecting trough 25 corresponding to the receiving position (a) and the collecting trough 25 corresponding to the evacuation position (b). ..

The above operation is repeated according to the article discharge status in the four collective troughs 25. As a result, the articles in a predetermined weight range are sequentially transferred to the four collecting troughs 25 by the two front and rear transfer conveyors 21.

The article w in a predetermined weight range put into the collective trough 25 is subjected to a vibration transfer action in a posture along the longitudinal direction of the concave and curved bottom surface, is transported while being aligned in parallel with each other, and is received by the collective trough shutter 29. Can be stopped. Further, at the time of loading the article from the conveyor 21, the pusher 33 is retracted to a position that does not interfere with the loading of the article. When the loading of the article is completed, the pusher 33 repeats advancing and retreating to the predetermined position (c) shown in FIG. 8 a predetermined number of times at a low speed so as to tap the rear end of the article w subjected to the vibration transporting action. Press to align the rear edges and wait at the predetermined position (c). The predetermined position (c) in which the pusher 33 waits after aligning the rear ends of the articles w is a position slightly rearward of the rear end positions of the articles w that are received and stacked by the shutter 29 for the collective trough. , The rear end of the article w received by the collective trough shutter 29 is not forcibly pressed.

When the collective trough shutter 29 is opened, the pusher 33 advances from the standby position at a higher speed in conjunction with this, and the aligned articles w in a predetermined weight range are pushed out and discharged from the collective trough 25 at once.

The article w discharged from the four collective troughs 25 is conveyed to the packaging process by appropriate means. For example, a tray-shaped transport tool supported by a robot arm or the like is made to stand by at a discharge point of the collective trough 25, and the articles w discharged from the collective trough 25 in an aligned state are received by the transport tool. Next, the transport tool is moved to the conveyor line of the packaging container, the article is transferred and loaded from the transport tool into the packaging container transported at a constant pitch, and then the packaging container containing the article is sent to the sealing process. , Etc. are processed.

The conveyor 21 is configured to be reversible. For example, when an excessive amount of articles that are difficult to be selected for an appropriate amount combination is supplied to the measuring hopper 7, the excessive amount of articles is discharged from the measuring hopper 7 to the conveyor 21 and the conveyor 21 is reversely driven. As a result, the excess article is discharged to the collection box 35 arranged on the opposite side of the collecting trough 25 as shown in FIG.

In the present embodiment, the article w is aligned by the three-stage linear feeder 5 so that its longitudinal direction is along the lateral direction which is the arrangement direction of the plurality of measuring units 4 and is supplied to the supply hopper 6 of the measuring unit 4. Will be done. The article w discharged from the weighing hopper 6 of the measuring unit 4 is conveyed along the lateral direction by the transport conveyor 21 and thrown into the collecting trough 25, and the collecting trough 25 causes the article w to have its longitudinal direction described above. It is rearranged along the lateral direction.

As described above, in the combination weighing device, the articles are processed in a state where the longitudinal direction thereof is along the lateral direction. Therefore, when the articles are carried out from the combination weighing device, the articles are processed in the lateral direction in the longitudinal direction. It is carried out in an aligned state with one layer aligned in the direction.
