Description

TECHNICAL FIELD The present invention relates to an article supply apparatus for supplying articles, and more particularly, an article supply apparatus suitable for, for example, supplying articles to a combination weigher that combines and weighs articles to be supplied and discharges articles within a predetermined weight range. Regarding.

A combination weigher has a plurality of weighing units, and selects a combination of weighing units in which the combined weight, which is the total weight of various combinations of the weights of articles supplied to each weighing unit, is within a predetermined weight range, and performs the selected weighing. It is intended to discharge the goods of the part.

Among such combination weighers, there is a so-called semi-automatic combination weigher in which articles are manually supplied and articles are automatically discharged. This semi-automatic combination weigher is suitable for handling irregular-shaped articles having a relatively large individual weight and articles that are difficult to handle mechanically, such as sticky pieces of meat such as chicken and seafood.

In such a semi-automatic combination weigher, for example, as described in Patent Document 1, a supply conveyor supplies articles (items to be weighed) onto the top plate of the combination weigher. The worker grabs the articles deposited on the top plate and puts them into the inlet of the combination weigher.

When the articles to be supplied to the combination weigher are articles such as chicken meat, for which freshness is important, which are regularly conveyed by a constant amount from the dismantling line on the upstream side in the article conveying direction. In the operation of the combination weigher, for example, when the packaging machine that packages the articles on the downstream side of the combination weigher stops temporarily due to replenishment or replacement of packaging bags, or when the operator of the combination weigher changes. In such a case, the articles pile up on the top plate of the combination weigher, even temporarily.

JP 2011-80895 A

When articles are automatically supplied to the combination weigher by the article supply device without manual intervention, there is no need for an operator to grasp the articles accumulated on the top plate and insert them into the input port of the combination weigher. , it is necessary to feed the articles directly to the input port of the combination weigher without feeding them to the top plate. In this case, the article supply device directly supplies the articles periodically conveyed by a constant amount from the dismantling line on the upstream side to the input port of the combination weigher without going through the top plate.

During the operation of the combination weigher, for example, a packaging machine on the downstream side of the combination weigher may temporarily stop due to replenishment or replacement of packaging bags. In this case, since there is no top plate for storing articles, when the article supply device is stopped, the articles conveyed from the dismantling line on the upper side to the article supply device are moved to the starting end of the article supply device on the uppermost side. , pile up and stay. For this reason, when the operation of the article supply device is resumed after the temporary stop, the piled articles cannot be smoothly conveyed, and the supply of the articles is hindered.

The present invention has been made by paying attention to such points, and it is possible to automatically supply articles to a supply destination, and at the same time, when the supply of articles to the supply destination is stopped, the article supply device can An object of the present invention is to prevent an article supplied from the side to the article supply device from stagnation.

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

(1) The present invention is an article supply device for supplying articles,
A first transport mechanism for transporting an article, and a switch between an allowable state in which the article is allowed to pass through the transport path of the article by the first transport mechanism and a discharge state in which the article is ejected outside the transport path . a second transport mechanism for transporting an article discharged out of the transport path by the article discharge mechanism toward a supply destination of the article of the article supply device; the first transport mechanism; and an article ejection mechanism, and a control section for controlling driving of the second transport mechanism, wherein the control section controls the first transportation mechanism to be in a driving state and the article ejection mechanism to be in the ejection state. Without switching, it is possible to control to the passage mode in which the article conveyed on the conveying route is controlled to the allowable state and passes through the conveying route without being discharged outside the conveying route ,
A control mode setting unit for performing a setting operation for setting a control mode by the control unit, and a stop operation for stopping the first conveying mechanism, the article discharging mechanism, and the second conveying mechanism. an operation unit, wherein the control mode setting unit can switch between a first control mode and a second control mode as the control mode, and the control unit is set to the first control mode. Sometimes, in response to the stop operation of the operation unit, all of the first transport mechanism, the article discharge mechanism, and the second transport mechanism are stopped, and when the second control mode is set, In response to the stop operation of the operation unit, the second transport mechanism is stopped and controlled to the pass mode .

The second conveying mechanism for conveying the article toward the supply destination of the article supply device may be one that conveys the article toward the supply destination, and may, for example, directly convey the article to the supply destination. Alternatively, the article may be conveyed to another conveying mechanism that directly supplies the article to the supply destination, that is, the article may be indirectly conveyed to the supply destination.

According to the article supply apparatus of the present invention, when articles are periodically supplied, for example, by a constant amount on the upstream side of the first conveying mechanism in the conveying direction, the articles to be supplied are conveyed by the first conveying mechanism. The second transport mechanism transports the ejected article to the article supply destination of the article supply device, and supplies the article to the supply destination. is supplied.

On the other hand, when it is necessary to stop the supply of the article to the article supply destination of the article supply device, the control section puts the first conveying mechanism in the driving state by controlling the passage mode, The article discharge mechanism is placed in the allowable state without switching to the discharge state, and the article conveyed along the conveying path can pass through without being discharged outside the conveying path. As a result, for example, an article that is periodically supplied by a constant amount on the upstream side of the first transport mechanism in the transport direction is not discharged by the article discharge mechanism, and is discharged by the first transport mechanism on the downstream side in the transport direction. Since the articles are conveyed to the side, unlike the case where the entire article supply device is stopped, the articles do not pile up and stay on the upper side of the article conveying direction of the first conveying mechanism. At the same time, the article discharging mechanism does not discharge the article to the second conveying mechanism that conveys the article to the article supply destination, and thus the article is not conveyed to the article supply destination.

According to the article supply apparatus of the present invention , when it is assumed that the supply of articles to the supply destination needs to be stopped during operation of the article supply apparatus, the control mode setting section is operated to The second control mode is set in advance, or when it becomes necessary to stop the supply of articles to the supply destination, the second control mode is set by operating the control mode setting unit.

When the supply of articles to the supply destination is to be stopped while the apparatus is operated in the state in which the second control mode is set, the second transport mechanism is stopped by performing a stop operation on the operation section, Control to pass mode.

As a result, for example, an article that is periodically supplied by a constant amount on the upstream side of the first conveying mechanism in the conveying direction of the article is not discharged by the article discharging mechanism, and is moved in the conveying direction by the first conveying mechanism. Since the articles are conveyed to the lower side of the article supply device, the articles are not piled up and stay on the upper side of the article conveying direction of the first conveying mechanism as in the case where the entire article supply device is stopped. In addition, the article discharging mechanism does not discharge the article to the second conveying mechanism that conveys the article toward the article supply destination of the article supply device, and therefore the article is conveyed toward the article supply destination. not even

Further, when the supply of articles from the upper side of the article supply device to the article supply device is stopped and the operation of the article supply device is stopped, the control mode setting section is operated to perform the second control. The mode is switched to the first control mode, and the operation unit is operated to stop. This makes it possible to stop all of the first transport mechanism, the article discharge mechanism, and the second transport mechanism, that is, to stop the article supply device.

( 2 ) The present invention is an article supply device for supplying articles,
A first conveying mechanism that conveys an article, and in a conveying path of the article by the first conveying mechanism, it is possible to switch between an allowable state in which the passage of the article is permitted and a discharge state in which the article is discharged outside the conveying path. a second conveying mechanism for conveying an article discharged from the conveying path by the article discharging mechanism toward a supply destination of the article of the article supplying device; a third conveying mechanism for further conveying the received article toward the article supply destination of the article supply device; the first conveying mechanism, the article discharging mechanism, the second conveying mechanism, and the third conveying mechanism wherein the control unit controls the first transport mechanism to the driving state and controls the article discharge mechanism to the allowable state without switching to the discharge state. , can be controlled to a passing mode in which an article conveyed through the conveying route is passed through without being discharged outside the conveying route;
A control mode setting unit for performing a setting operation for setting the control mode by the control unit, and for stopping the first transport mechanism, the article discharge mechanism, the second transport mechanism, and the third transport mechanism. The control mode setting unit can switch and set a first control mode and a second control mode as the control mode, and the control unit can perform the first control when the mode is set, stopping all of the first transport mechanism, the article discharge mechanism, the second transport mechanism, and the third transport mechanism in response to the stop operation of the operation unit; When the second control mode is set, the second transport mechanism and the third transport mechanism are stopped in response to the stop operation of the operation unit, and are controlled to the pass mode.

According to the present invention, the article conveyed by the second conveying mechanism is further conveyed by the third conveying mechanism toward the supply destination of the article. Thus, it becomes easy to supply the goods at the timing according to the demand of the supply destination of the goods.
According to the present invention , when it is assumed that it will be necessary to stop the supply of articles to the supply destination during operation of the article supply apparatus, the control mode setting section is operated to set the second The control mode is set in advance, or when it becomes necessary to stop the supply of articles to the supply destination, the control mode setting unit is operated to set the second control mode.

When the supply of articles to the supply destination is to be stopped while the operation is being performed in the state in which the second control mode is set, the second transport mechanism and the third transport mechanism are operated by performing a stop operation using the operation unit. is stopped while controlling to pass mode.

As a result, the article supplied to the upper side in the conveying direction of the first conveying mechanism is conveyed to the lower side in the conveying direction by the first conveying mechanism without being discharged by the article discharging mechanism. Unlike the case where the entire apparatus is stopped, articles are not piled up and stay on the upper side of the first conveying mechanism in the conveying direction. Also, the article discharging mechanism does not discharge the article to the second conveying mechanism that conveys the article toward the supply destination of the article, and therefore the article is not conveyed toward the supply destination.

Further, when the supply of articles from the upper side of the article supply device to the article supply device is stopped and the operation of the article supply device is stopped, the control mode setting section is operated to perform the second control. The mode is switched to the first control mode, and the operation unit is operated to stop. As a result, all of the first transport mechanism, article discharge mechanism, second transport mechanism, and third transport mechanism can be stopped, that is, the article supply device can be stopped.

According to the present invention, when an article is periodically supplied, for example, by a constant amount, on the upstream side of the article conveying direction of the first conveying mechanism, the article to be supplied is conveyed by the first conveying mechanism. The second transport mechanism transports the ejected article to the article supply destination of the article supply device, and supplies the article to the supply destination. is supplied.

On the other hand, when it is necessary to stop the supply of the article to the article supply destination of the article supply device, the control section puts the first conveying mechanism in the driving state by controlling the passage mode, The article discharge mechanism is placed in the allowable state without switching to the discharge state, and the article conveyed along the conveying path can pass through without being discharged outside the conveying path. As a result, for example, an article that is periodically supplied by a constant amount on the upstream side of the first transport mechanism in the transport direction is not discharged by the article discharge mechanism, and is discharged by the first transport mechanism on the downstream side in the transport direction. Since the articles are conveyed to the side, unlike the case where the entire article supply device is stopped, the articles do not pile up on the upper side of the first conveying mechanism in the conveying direction. At the same time, the article discharging mechanism does not discharge the article to the second conveying mechanism that conveys the article toward the article supply destination of the article supply device, and therefore the article is conveyed toward the article supply destination. not even

FIG. 7 is a block diagram showing the control configuration of the weighing system of this embodiment.

The weighing system of this embodiment includes a programmable controller (hereinafter abbreviated as "PLC") 27 as a control device (control section) for overall control.

The PLC 27 has three control modes, a normal mode, a stop mode, and a passage mode, and controls the article supply device 1 in any one of the control modes. In the normal mode, the preceding conveying mechanism 3, the article discharging mechanism 4, the distributing conveying mechanism 5, and the vibrating feeder 6 are controlled to be driven. In the stop mode, the former conveying mechanism 3, the article discharging mechanism 4, the distributing conveying mechanism 5, and the vibrating feeder 6 are all controlled to be in a stopped state. In the pass mode, the preceding conveying mechanism 3 is controlled to be driven, the article discharge mechanism 4 is controlled to be allowed, and the distribution conveying mechanism 5 and vibrating feeder 6 are controlled to be stopped.

The PLC 27 is connected to a programmable display 29 which is an operation display terminal having functions as a control mode setting section for setting a control mode and an operation section for performing a stop operation and the like. On this programmable display 29, various setting operations and stopping operations such as the conveying speed of the pre-stage conveying mechanism 3 and the revolving conveyor 14 and the vibration intensity of the vibrating feeder 6, and various displays are performed.

Further, the PLC 27 receives discharge request signals (1) to (9) when requesting discharge of articles from the control unit 28 of the semiautomatic combination weigher 2 to each of the nine article inlets 25. and the article detection sensors Sa(1) to Sa(3), Sb(1) to Sb(3), Sc(1) to Sc(3), Sd(1) to Sd(3), Detection outputs of Se(1) to Se(9) and Sf(1) to Sf(9) are input.

The PLC 27 controls the front transport mechanism 3 via a front transport mechanism drive control circuit 30 and controls each guide member 8 of the article discharge mechanism 4 via a guide member drive circuit 31 . In addition, the PLC 27 controls each revolving conveyor 14 of each distribution transport mechanism 5 via a revolving conveyor drive control circuit 32 and a revolving conveyor revolving drive control circuit 33, and controls each vibrating feeder 6 via a vibrating feeder drive circuit 34. to control.

In the control of the article supply device 1 by the PLC 27, the vibrating feeder 6, which is the lowest in the article conveying direction in the article supply device 1, is controlled, and then the distributing and conveying mechanism 5, which is the upper side, is controlled. It controls the article ejection mechanism 4, which is the best of them.

This PLC 27 basically controls so that when there is a request to discharge an article from the combination weigher 2 to each article inlet 25, the article can be immediately discharged to the requested article inlet 25. Control is performed so that the article can be conveyed to the terminal end of the trough 15 of each vibrating feeder 6 and wait.

That is, in the vibration feeder 6, when there are no articles at the end of the trough 15, the articles detected at the beginning of the trough 15 are conveyed to the end of the trough 15, and the articles detected at the beginning of the trough 15 are conveyed to the end of the trough 15. If not, it requests the revolving conveyor 14 of the distribution transport mechanism 5 to throw in the articles.

The revolving conveyor 14 of the distribution transport mechanism 5 conveys the articles to the end of the revolving conveyor 14 and controls the rotational position so that the article can be immediately thrown into the trough 15 of the vibrating feeder 6 when the article is requested. be done. When there is no article at the end of the turning conveyor 14, the article detected at the beginning of the turning conveyor 14 is conveyed to the end, and when no article is detected at the beginning of the turning conveyor 14, the article discharge mechanism 4 Request the input of goods.

When an article passing through the detection area in front of the article ejection mechanism 4 is detected, the article ejection mechanism 4 that has received an article input request drives the guide member 8 to take the ejection posture of advancing to the transportation path, and the article is transported. The article is supplied to the revolving conveyor 14 of the distributing and conveying mechanism 5 outside the conveying route.

Specifically, the detection output of the first article detection sensors Sa(1) to Sa(3) for detecting the articles w passing through the detection area immediately before each article discharge mechanism 4 on the conveyance path of the preceding conveying mechanism 3. Based on this, the PLC 27 can start discharging articles at a plurality of locations on the conveying route by controlling the switching of the article discharging mechanism 4 to the discharging state. Further, based on the detection outputs of the second article detection sensors Sb(1) to Sb(3) that detect the article w discharged by each article discharge mechanism 4, the PLC 27 detects the article discharge after the article is discharged. By controlling the switching of the mechanism 4 to a permitting state in which passage of articles is permitted, it is possible to terminate the discharge of articles at a plurality of locations on the conveying route.

While the second article detection sensors Sb(1) to Sb(3) are detecting articles to be ejected, the PLC 27 is continuously provided with detection outputs. The PLC 27 determines the duration of the ejection state of the article ejection mechanism 4 based on the duration of the detection outputs of the second article detection sensors Sb(1) to Sb(3), that is, the article ejection mechanism 4 distributes and conveys the articles. Controls the time to discharge to 5.

As described above, in the article discharge mechanism 4 that has received a request to load an article, the guide member 8 is driven to take the discharge posture of advancing into the conveying path, and the conveyed article is moved out of the conveying path by the turning of the distributing conveying mechanism 5 outside the conveying path. Since the article w is supplied to the conveyor 14, the articles w supplied from the starting end side of the conveying belt 7 of the preceding conveying mechanism 3 are sent to the three revolving conveyors by the article discharge mechanism 4 in response to the article input request from the revolving conveyor 14. 14.

As described above, when there is a request to discharge an article from the combination weigher 2 to each article inlet 25, the article is discharged from the vibrating feeder 6 to the requested article inlet 25, and vibration occurs when the trough 15 is empty of articles. Articles are put into the feeder 6 from the distributing and conveying mechanism 5, and the articles are discharged by the article discharging mechanism 4 and supplied to the distributing and conveying mechanism 5 that has run out of articles.

Therefore, when the amount of articles discharged from the article supply device 1 exceeds the weighing processing capacity of the combination weigher 2, there is no demand to discharge the articles from the combination weigher 2. FIG. Since there is no request to discharge the articles, the vibrating feeder 6 does not discharge the articles to the combination weigher 2, and when there are articles in the vibrating feeder 6, the distributing conveying mechanism 5 is not requested to input the articles. Since there is no request to load the articles, the distributing and conveying mechanism 5 does not feed the articles to the vibrating feeder 6, and when there are articles in the distributing and conveying mechanism 5, the article discharging mechanism 4 is not requested to supply the articles. Since there is no request to supply an article, the article discharging mechanism 4 does not supply any article to the distribution conveying mechanism 5, and the article supplied to the leading end of the conveying belt 7 of the preceding conveying mechanism 3 passes through the article discharging mechanism 4. , is conveyed to the end side of the conveying belt 7 .

That is, when the amount of articles supplied to the front-stage conveying mechanism 3 of the article supply device 1 temporarily exceeds the weighing throughput of the combination weigher 2, the articles conveyed by the front-stage conveying mechanism 3 are This can be dealt with by allowing the sheet to pass through the guide member 8 of the ejection mechanism 4 without ejecting it.

As described above, in this embodiment, when the articles are supplied from the broiler dismantling line on the upper side of the conveying direction of the preceding conveying mechanism 3, the guide members 8 of the article discharging mechanism 4 guide the articles outside the conveying path at three points on the conveying path. are discharged to each revolving conveyor 14 of each of the three distributing and conveying mechanisms 5 of . The discharged articles are sorted and conveyed to the troughs 15 of the three vibrating feeders 6 by the revolving conveyors 14 . That is, the articles supplied to one place on the upstream side of the conveying direction of the pre-stage conveying mechanism 3 are sorted and conveyed to the respective troughs 15 of the nine vibrating feeders 6, and the respective troughs 15 of the respective vibrating feeders 6 feed the articles at the supply destination. It can be supplied to each of the nine article inlets 25 of a certain combination weigher 2 . The combination weigher 2 performs combination weighing to supply articles w within a predetermined weight range to a packaging machine (not shown) on the downstream side, where the articles are packaged.

As in the present embodiment, in a system that weighs an article and packs it with a packaging machine, the packaging unit of the article by the packaging machine may be changed, for example, the packaging unit of 1 kg may be changed to the packaging unit of 2 kg. Also, the type of product may be changed, for example, the product may be changed from broiler to free-range chicken. In the following description, the term "variety" may include "packaging unit of goods" and "kind of goods".

When changing the product type, the operation of the article supply device 1, the combination weigher 2, and the packaging machine is temporarily stopped. For example, necessary work such as replacing the packaging material is performed.

In the article supply apparatus 1 of this embodiment, it is not possible to shift to the operation in which the product type is changed during operation. It has become.

While the article supply device 1 is temporarily stopped, the supply of articles from the dismantling line on the upstream side of the article supply device 1 is not stopped, and the articles are conveyed in the conveying direction of the conveying belt 7 of the preceding conveying mechanism 3. continue to be supplied to the starting end which is the upper side of the Even when the type of product is changed, for example, when broilers are changed to free-range chickens, the dismantling line is not stopped, and the supply interval between the broilers and free-range chickens is only slightly widened.

In this embodiment, the PLC 27 is installed at the leading end of the conveying belt 7 of the preceding conveying mechanism 3 to prevent the supplied articles from accumulating in a pile while the article supplying apparatus 1 is stopped. A first control mode corresponding to a case where the dismantling line is stopped, articles are not supplied to the article supply device 1 and the operation of the article supply device 1 is stopped, and a dismantling line is not stopped. , and a second control mode corresponding to a case in which articles are supplied to the article supply device 1 and the article supply device 1 is temporarily stopped in order to change the product type, by operating the programmable display 29. Switching can be set.

When the interlocking mode as the first control mode is set, the PLC 27 stops the entire article supply apparatus 1 when the programmable display 29 is operated to stop the article supply apparatus 1 during operation. That is, the conveying belt 7 of the preceding conveying mechanism 3, the guide member 8 of the article discharging mechanism 4, the distributing conveying mechanism 5, and the vibrating feeder 6 are all stopped.

This interlocking mode is used to stop the article supply device 1 mainly when the operation of the entire weighing system is to be stopped. This is the case where the scale 2 and the packaging machine are also stopped.

In this interlocking mode, when the programmable display 29 is operated to start the operation, the entire operation of the article supply apparatus 1 is started. That is, all of the conveying belt 7 of the preceding conveying mechanism 3, the guide member 8 of the article discharging mechanism 4, the distributing conveying mechanism 5, and the vibrating feeder 6 are brought into operation, and normal operation is started.

When the independent mode as the second control mode is set and the stop operation is performed by the programmable display 29 during operation of the article supply device 1, the PLC 27 stops the distribution transport mechanism 5 and the vibrating feeder 6. On the other hand, it controls to pass mode. In this passing mode, the conveying belt 7 of the preceding conveying mechanism 3 is controlled to the driving state without being stopped, and the guide member 8 of the article discharging mechanism 4 is not switched to the discharging state obliquely intersecting the conveying path. Control is performed to allow the retracted posture along the transport direction. As a result, in the passage mode, the article conveyed by the conveying belt 7 of the preceding conveying mechanism 3 passes through the article discharging mechanism 4 without being discharged outside the conveying path, and is conveyed to the lower side in the conveying direction of the article. be done.

The article supply device 1 is stopped in this independent mode when it is necessary to temporarily stop the article supply device 1, the combination weigher 2, and the packaging machine, such as when changing the product type. .

By stopping in this independent mode, the articles supplied from the dismantling line pass through the article discharge mechanism 4 without being discharged out of the conveying path by the article discharge mechanism 4, and are downstream of the conveying belt 7 of the preceding conveying mechanism 3. Since the articles are conveyed to the front end of the conveying mechanism 3, the articles do not accumulate in a pile at the leading end of the conveying belt 7 of the preceding conveying mechanism 3.

Also, the articles are not discharged out of the conveying path and supplied to the distributing conveying mechanism 5 by the article discharging mechanism 4, and the articles are supplied to the article inlet 25 of the temporarily stopped combination weigher 2. Not at all.

When it is desired to stop the article supply device 1, the programmable display 29 is operated to switch the control mode from the independent mode to the interlocking mode, and the programmable display 29 is stopped.

The PLC 27 controls the article supply device 1 in the stop mode in response to the stop operation of the programmable display 29 when the linked mode is set, and stops the programmable display 29 when the independent mode is set. In response to the operation, the article feeder 1 is controlled to the pass mode.

A case of changing the product type will be described in detail below.

First, the case of changing the packaging unit of an article will be described.

Assuming that there will be a change in the product type, the programmable display 29 is operated to set the single mode, or the single mode is set before the product change.

When the unit of packaging is changed to 2 kg while the unit of packaging of the article is being operated, for example, the unit of packaging is 1 kg, the programmable display 29 is stopped and the operation of the article supply apparatus 1 is temporarily stopped as described above. Stop. As a result, the distribution/conveyor mechanism 5 and the vibrating feeder 6 are stopped and set to the passing mode. In this passing mode, the conveying belt 7 of the preceding conveying mechanism 3 is controlled to be in a driving state, and the guide member 8 of the article discharging mechanism 4 is not switched to the discharging state, but is controlled to allow articles to pass. .

As a result, the articles supplied from the broiler dismantling line to the pre-conveyance mechanism 3 of the article supply device 1 pass through the article discharge mechanism 4 without being discharged out of the conveying path by the article discharge mechanism 4, and are transferred to the pre-conveyance mechanism. Since the articles are conveyed to the lower side of the conveying belt 7 of 3, the articles are not piled up and stay at the leading end of the conveying belt 7 of the preceding conveying mechanism 3.例文帳に追加

The operation of the article supply device 1 is stopped in the single mode, and the operation of the combination weigher 2 and the packaging device is temporarily stopped. In the combination weigher 2, for example, settings such as the target combination weight are changed, and in the packaging machine, for example, necessary operations such as replacing the packaging material are performed.

Also in the article supply device 1, the programmable display 29 of the article supply device 1 is operated to change the setting corresponding to the change of the product type, for example, the setting change of the vibration parameter of the vibrating feeder 6 and the like.

After that, the programmable display 29 of the article supply device 1 is operated to switch the control mode from the single mode to the interlocking mode. Then, while restarting the operation of the combination weigher 2 and the packaging machine, the programmable display 29 of the article supply device 1 is operated to restart the operation.

When changing the packing unit of articles in this way, by setting the independent mode, when the stop operation for stopping the operation of the article supply apparatus 1 is performed, the conveying belt 7 of the preceding conveying mechanism 3 is driven. At the same time, the guide member 8 of the article discharging mechanism 4 is not switched to the discharging state, but is in the passing mode controlled to the allowable state, so that the starting end of the conveying belt 7 of the preceding conveying mechanism 3 is removed from the broiler cutting line. The article supplied to the unit passes through the article ejection mechanism 4 without being ejected outside the conveying path by the article ejection mechanism 4, and is conveyed downstream by the conveying belt 7. It is not piled up and stays at the leading end of the conveying belt 7.例文帳に追加

In the case of a change in the packaging unit of an article, since the type of article is not changed, the article remaining on the revolving conveyor 14 and the vibrating feeder 6 of the distributing and conveying mechanism 5 due to the stopping of the distributing and conveying mechanism 5 and the vibrating feeder 6 is supplied to the combination weigher 2 as it is by restarting the operation.

Next, a case of changing the type of article, for example, changing the type of article supplied from the dismantling line to the article supply device 1 from broiler to free-range chicken will be described.

Single mode is set by the programmable display 29 as well as changing the packaging unit of the goods.

When changing the broiler to a free-range chicken during operation when the type of article supplied from the dismantling line to the article supply device 1 is broiler, it is necessary to temporarily stop the operation of the article supply device 1. Stop the programmable display 29 of the feeder 1 . The timing of this stop operation is preferably after the broilers of the type before the change are supplied from the vibrating feeder 6 to the article inlet 25 of the combination weigher 2 .

A stop operation in the independent mode causes the distribution/conveyor mechanism 5 and the vibrating feeder 6 to stop, while being controlled to the pass mode. In this passing mode, the conveying belt 7 of the preceding conveying mechanism 3 is controlled to be in a driving state, and the guide member 8 of the article discharging mechanism 4 is not switched to the discharging state, but is controlled to allow articles to pass through. .

Along with stopping the operation of the article supply apparatus 1 in the independent mode, the operation of the combination weigher 2 and the packaging apparatus is temporarily stopped, and required operations are carried out.

Also in the article supply device 1, the programmable display 29 of the article supply device 1 is operated to change the setting corresponding to the change in the kind of article.

After that, the programmable display 29 of the article supply device 1 is operated to switch the control mode from the single mode to the interlocking mode. Then, the operation of the combination weigher 2 and the packaging machine is restarted, and the programmable display 29 of the article supply device 1 is operated to restart the operation.

When the operation of the article supply device 1 is stopped when the type of article is changed in this way, the conveyor belt 7 of the preceding conveying mechanism 3 is driven and the guide member 8 of the article discharging mechanism 4 is switched to the discharging state. Therefore, the articles supplied from the dismantling line to the leading end of the conveying belt 7 are not discharged outside the conveying route by the article discharging mechanism 4, and the article discharging mechanism 4 is operated. Since the articles pass through and are conveyed to the downstream side by the conveying belt 7, the articles do not pile up at the leading end of the conveying belt 7 of the preceding conveying mechanism 3.例文帳に追加

In addition, in the case of changing the type of goods, the timing of the stop operation as described above,
By setting the timing after the broilers of the type before the change are supplied from the vibrating feeder 6 to the article inlet 25 of the combination weigher 2, by stopping the distributing and conveying mechanism 5 and the vibrating feeder 6, the distributing and conveying mechanism 5 The article remaining on the revolving conveyor 14 and the vibrating feeder 6 becomes free-range chicken, which is the article after the change. Therefore, when the operation is restarted, the combination weigher 2 is supplied with the free-range chicken after the change.

In addition, if the timing of the stop operation is shifted and the broiler of the type before the change remains on the revolving conveyor 14 or the vibrating feeder 6 of the distribution transport mechanism 5, the operator must remove the revolving conveyor before restarting the operation. 14 or the vibration feeder 6, or the operation of the article supply device 1 is restarted, and the broiler of the type before the change is discharged from the vibration feeder 6 to the article input port 25 of the combination weigher 2, and the change is performed. While free-range chicken, which is the latter kind, is discharged to the article inlet 25 of the combination weigher 2, the collection conveyor 43 of the combination weigher 2 is reversely driven to convey the articles in the direction opposite to the packaging machine, and the broiler is operated. may be excluded.

As described above, according to the present embodiment, when changing the type of product, the single mode is set and the stop operation is performed to drive the conveyor belt 7 of the preceding conveying mechanism 3 and the article discharging mechanism 4. Since the guide member 8 is controlled to the passage mode in which the guide member 8 is controlled to the allowable state without being switched to the discharging state, the articles supplied from the dismantling line to the leading end of the conveying belt 7 are piled up at the leading end of the conveying belt 7. There is no stagnation and no articles are supplied to the combination weigher 2.

Further, according to the present embodiment, when an article is supplied from the upper side of the conveying direction of the preceding conveying mechanism 3, the guide members 8 of the article discharging mechanism 4 guide the three units outside the conveying path at three points on the conveying path. It is discharged to each revolving conveyor 14 of the distribution transport mechanism 5 . The discharged articles are sorted and conveyed to the troughs 15 of the three vibrating feeders 6 by the revolving conveyors 14 . That is, the articles supplied to one place on the upstream side of the conveying direction of the preceding conveying mechanism 3 are sorted and conveyed to the respective troughs 15 of the nine vibrating feeders 6 , and the troughs 15 of the respective vibrating feeders 6 feed the nine weighers 2 . can be supplied to each article slot 25.

Therefore, the articles w, which are broiler meat pieces having stickiness, can be automatically supplied to the nine article inlets 25 of the combination weigher 2, and the operator can grasp the articles one by one and semi-automatically There is no need to carry out the work of putting the articles into the article inlet of the combination weigher, and the labor of the operator can be greatly reduced.
