DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the layout of the packaging weighing and pricing apparatus and the flow of the tray T. In FIG. 1A, a tray T on which a product M is placed is intermittently transferred onto a lifter 10 by a supply conveyor device 2 in an unpackaged state.

As shown in FIG. 2, a packaging mechanism 11 is provided above the lifter 10. The packaging mechanism 11 wraps the product M together with the tray T by folding the film F indicated by a two-dot chain line into the bottom side Tb of the tray T at the upper lap station S. A sealing device 19 is disposed in front Fo of the lap station S. The sealing device 19 heat seals the folded portions of the film F folded into the bottom surface Tb of the tray T.
The heat-sealed packaged product A in FIG. 1B is transferred onto the weighing conveyor 4 by the direction change conveyor 3, and the weight of the product M is measured while being transferred by the weighing conveyor 4. Thereafter, the packaged product A is transported to below the pricing device 5 by the bonding machine conveyor 5a, and then a label on which a product code, a weight, and the like are printed is affixed.

Next, the above components will be described in detail. 2, the supply conveyor device 2 includes a stock conveyor 21, a cutting stopper 22, a supply conveyor 23, and a clawed conveyor 24 supported by a frame (not shown). In the supply conveyor device 2, the cutout stopper 22 is retracted downward, and only one tray T is cut out due to the speed difference between the stock conveyor 21 and the supply conveyor 23. When the claw 24c stops, the tray T is put on standby.
The round belt 23b of the supply conveyor 23 is constantly driven to rotate, and the claw 24c of the clawed conveyor 24 rotates downward and retracts, thereby transferring the tray T onto the lifter 10. Each of the conveyors 21, 23, and 24 is driven to rotate by a drive motor (not shown). Reference numeral 26 denotes a back stopper.

The lifter 10 includes a lap station S
And a lifting mechanism driven by a drive motor (not shown), so that it can be moved up and down. The lifter 10 includes the supply conveyor device 2
When the tray T is transferred from the wrap station S, the tray T is lifted by a certain stroke and lifted, and the tray T is pressed against the lower surface of the film F held in tension at the lap station S.

On the other hand, as shown by the solid line, a film F is supplied to the lap station S in a state where the film F is sandwiched by the film feeder 6. Adhere to the upper surface of M. In this state, the packaging mechanism 11 moves the front, rear, left, and right side edge portions of the film F as described below.
It is folded into the bottom side Tb of the tray T and the tray
Packaging.

The packaging mechanism 11 includes a pair of left and right folding plates (folding members) 15, a rear folding plate (folding member) 16, and a round bar-shaped front folding member 17. Left and right folding plate 15
Moves back and forth in the left-right direction (the direction perpendicular to the paper surface). On the other hand, the rear folding plate 16 moves forward and backward in the front-back direction Fo. The left and right folding plates 15 and the rear folding plate 16 are provided on the bottom surface Tb of the tray T.
, The film F is folded toward the bottom surface of the tray T. The pusher 13 is driven at a predetermined timing slightly delayed from the rear folding plate 16, and with the operation of discharging the product M by the pusher 13, the front folding member 1 is moved.
7 folds the side edge of the front Fo of the film F into the bottom side Tb of the tray T. The folding plates 15, 16 and the pusher 13 are driven by a drive motor. Each film feeder 6 includes a pair of transport belts 61 and 62.

In FIG. 1B, the direction change conveyor 3, the weighing conveyor 4, and the laminating machine conveyor 5a are driven by a drive motor (not shown), and transport the packaged goods A from the packaging apparatus 1 to the pricing apparatus 5. To form a transfer device. The weighing conveyor 4 includes a load cell (not shown), weighs the weight of the product M while the packaged product A is being transported, and is constantly driven to rotate.

Next, the pricing device 5 will be described. In FIG. 3, the pricing device 5 is configured to attach a label La indicating the price of the product M or the like to the film F of the product M and price the label La. The label printer 54 and the label pasting machine 5
1 and 1. The label printer 54 prints and issues the weight and price of the product M on a label La based on a signal from a microcomputer (not shown). The label pasting machine 51 pastes the label La issued from the label printer 54 onto the package A on the pasting machine conveyor 5a.

Inside the label printer 54, there is arranged a roll Ro of a label sheet Ls formed by removably attaching a large number of labels La to a band-shaped mount. While the label sheet Ls pulled out from the roll Ro passes between the print head 54a and the platen roller 54b, the weight, price, and the like of the product M are printed on the label La on the label sheet Ls. The label La is discharged while being peeled off from the tip side by a peeling bar (not shown). In the label sticking machine 51, the suction pad 52 that sucks the label La by negative pressure descends a predetermined stroke from the position indicated by the solid line to the position indicated by the two-dot chain line, and applies the label La to the package A. The suction pad 52 moves up and down by forward and reverse rotation of a pad drive motor 53.

Next, the arrangement of the tray detector for detecting the tray T will be described. The tray detector includes a downstream position P1 of the cutting stopper 22 in FIG. 2, a standby position P2 just before the lifter 10, a lowered position P3 when the lifter 10 is lowered,
Turning position P4 on the turning conveyor and FIG.
At the label affixing position P5 in (b), the tray T is disposed at a position where the tray T can be detected. As each detector, a photodetector and a proximity switch can be used. The weighing conveyor 4 detects the passage of the package A based on the load applied to the load cell.

Next, a description will be given of a processing capacity control device which is a main part of the present invention. In FIG. 4, the processing capacity control device 7 includes a product information processing means 70 built in the microcomputer, a packaging weighing device control means 71, a keyboard 72, an operator value setting section 73, and motor controllers MC1 to MCN. . The product detection signal aM from the load cell and tray detector described above is input to the package weighing and value adding device control means 71. The control unit 71 controls the timing of transporting the tray T based on the product detection signal aM and cooperates with the product information processing unit 70 that recognizes the item information of the package A. Then, by determining which item of the package A is present at each of the detection positions P1 to P5 (FIG. 1), a well-known tracking control for matching the package A with the item of the package is performed. The items of the package are determined by the type of the product and the tray.

The product information processing means 70 has a product information storage means 70a and a fundamental frequency storage means 70b. The merchandise information storage means 70a stores merchandise information such as a unit price and a shelf life for each kind of merchandise or item. On the other hand, the fundamental frequency storage means 70b
The basic frequency (a set value corresponding to the set number of rotations of each drive motor, indicating the processing capacity of the packaging device ) BHZ is shown in FIG.
As shown in (a), it is stored for each item. The product information processing means 70 in FIG. 4 reads out the basic frequency BHZ for the items supplied to the supply conveyor device 2 (FIG. 1) from the basic frequency storage means 70b and outputs it to the package weighing value control device control means 71. . Note that the fundamental frequency BHZ
May be input from the keyboard 72, or may be set and registered in the test mode as described later.

The operator value setting section 73 inputs an operator value Op corresponding to the supply capacity of the operator when the operator performs a rotation operation.
In this specification, the supply capability of the operator refers to the processing capability of the operator placing a product on a tray and supplying the product to the supply conveyor device 2 (FIG. 2).

The package weighing device control means 71 includes a selection means 71a, a frequency ratio storage means 71b, each frequency calculation means 71c, and each frequency storage means 71d. The selecting means 71a compares the operator value Op with the fundamental frequency BHZ corresponding to the type of the item, and
When the two values Op and BHZ are different from each other, the smaller value is selected, and the selected value SHZ is set to each frequency calculating means 71c.
Output to The selection means 71a sets the operator value O
When p and the basic frequency BHZ are the same, the basic frequency BHZ is output as the selected value SHZ.

The frequency ratio storage means 71b is provided as shown in FIG.
As shown in (b), the frequency ratios α1 to αN corresponding to the types of the drive motors are stored. Above frequency ratio α1 to αN
Is a value set in advance so that the cycle of each process from the supply of the tray to the attachment of the label substantially coincides with each other. 4 reads out the frequency ratios α1 to αN stored in the frequency ratio storage unit 71b, multiplies the selected value SHZ by the frequency ratios α1 to αN, and sets the drive motors M1 to MN. Drive frequency β1 to β
N is sequentially output to each frequency storage means 71d, and each drive frequency β1 to βN is stored in each frequency storage means 71d. The control unit 71 outputs the drive frequencies β1 to βN stored in the frequency storage unit 71d to the motor controllers MC1 to MCN.

Each of the motor controllers MC1 to MCN includes:
The drive motors M1 to MN such as the above-described supply conveyor device 2 and lifter 10 (FIG. 2) are rotated at a rotational speed proportional to the drive frequencies β1 to βN. That is, the motor controllers MC1 to MCN control the rotation speeds of the respective drive motors M1 to MN based on the selection value SHZ selected by the selection means 71a. The motor controller MC1
The control of the number of rotations of the drive motors M1 to MN by .about.MCN is performed, for example, by controlling an inverter to convert a DC power supply into an AC having the above-mentioned drive frequencies .beta.1 to .beta.N and supply this to an AC motor.

Next, the basic operation of the above-mentioned packaging weighing and value adding apparatus will be described. First, the operator operates as shown in FIG.
Conveyor device 2 for supplying a tray T on which a product M is placed as shown in FIG.
Is placed on the stock conveyor 21. The placed tray T comes into contact with the cutout stopper 22 in FIG. 2 and is stocked on the stock conveyor 21. Cutout stopper 2
After the 2 has retreated, the tray T stops temporarily before the lifter 10 and then moves onto the lifter 10.

After the transfer, the tray T is placed on the lifter 10
Is pushed up by the upper lap station S,
As described below, the wrap station S wraps the product M together.

As shown by the solid line in FIG.
Is held in a stretched state. Therefore, when the tray T is pushed up by the lifter 10, the film F comes into close contact with the upper surface and the upper end of the product M and the tray T.

In this state, when the pair of left and right folding plates 15 move in the left-right direction (the direction perpendicular to the paper surface) along the bottom surface Tb of the tray T, the film F is folded toward the bottom surface of the tray T. Thereafter, the rear folding plate 16 moves forward Fo, and the film F is folded on the bottom side of the tray T. Slightly behind the advance of the rear folding plate 16, the pusher 13
Moves to the front Fo and pushes out the tray T to the front Fo.
Along with this extrusion, the front folding member 17 causes the tray T
The film F is folded into the bottom surface side of the front part of. afterwards,
The film F is heat-sealed by the sealing device 19.

The packaged product A thus packaged is shown in FIG.
As shown in (b), it is transferred from the direction changing conveyor 3 through the measuring conveyor 4 to the laminating machine conveyor 5a. Package A
After the weight is detected on the weighing conveyor 4, it temporarily stops on the pasting machine conveyor 5 a, and the labeling device 5 affixes a label having a content based on the information on the item or the weight.

Next, a description will be given of a method of controlling the processing capacity of the packaging weighing and value adding apparatus. First, the operator inputs the type of the tray T to be placed on the supply conveyor device 2 and the product number of the product M from the keyboard 72 in FIG. The product information processing means 70 determines the type of the input tray T and the product M
5 (a) based on the product number of
The basic frequency BHZ stored in 0b is output to the selecting means 71a of the control unit 71 for controlling the weighing and weighing device in FIG.
On the other hand, the operator inputs the operator value Op corresponding to the supply capacity of the operator by rotating the operator value setting unit 73.

The operator value O of the operator value setting section 73
When p is set to the maximum value, the operator value Op is larger than the basic frequency BHZ input to the selecting means 71a, so the selecting means 71a sets the basic frequency BHZ as the selected value SHZ, and Output to the means 71c. The frequency calculation means 71c reads out the frequency ratios α1 to αN from the frequency ratio storage means 71b of FIG.
By multiplying the selected value SHZ by the frequency ratios α1 to αN, the drive frequency β1 corresponding to the rotation speed of the drive motors M1 to MN is obtained.
To βN, and the driving frequencies β1 to βN are stored in the respective frequency storage means 71d. After that, the packaging weighing device control means 71 converts the drive frequencies β1 to βN stored in the frequency storage means 71d into the motor controllers MC1 to MCN.
Output to MCN. The motor controllers MC1 to MC
The CN rotates the drive motors M1 to MN based on the input drive frequencies β1 to βN. Therefore, in the case of a skilled operator, each product M and tray T
Drive motors M1 to MN are rotationally driven in accordance with the type of item determined by the size of.

Here, the basic frequency BHZ stored in the basic frequency storage means 70b may be used to store the commodity M in the tray T or the commodity M falling in the tray T in transporting the item. If the value is set to a large value within a range that does not exist, the cycle time of packaging can be shortened, and the product M can be packaged without any trouble.

On the other hand, when the operator value Op of the operator value setting section 73 is smaller than the maximum value, that is, when the operator value Op is set to a value corresponding to the supply capacity of the operator, the selection means 71a sets the basic frequency BHZ to Operator value O
When the two values BHZ and Op are different from each other, the selecting means 71a selects the smaller value and outputs the selected value SHZ. For example, if the operator value Op is 45
In Hz, the fundamental frequency BHZ of the item in FIG.
Hz or less, the fundamental frequency BHZ is kept at the selected value S as it is.
HZ is output to the frequency calculation means 71c in FIG.
In this case, the cycle time of packaging can be reduced as in the case of the above-mentioned skilled operator.

On the other hand, when the operator value Op is 45 Hz and the basic frequency BHZ of the item in FIG. 5A is 50 Hz, the operator value Op in FIG.
It is output to the frequency calculation means 71c. In this case, since the number of rotations of each of the drive motors M1 to MN becomes small, the processing capacity of the package weighing and value adding apparatus is reduced. However, the supply capacity of the operator was low, and the processing capacity of the apparatus was reduced according to the supply capacity of the operator.
The number of items that are actually packaged is not substantially reduced. On the other hand, the drive motors M1 to MN
Since the number of rotations is not increased, troubles can be reduced, and machine wear, noise, power consumption, and the like can be reduced.

Next, a method of registering the fundamental frequency BHZ will be described. When registering the basic frequency BHZ, a registration mode is set, and the basic frequency BHZ is input from the keyboard 72. After this input, the tray T on which the product M of FIG. 1 is placed is placed on the supply conveyor device 2 and actually packed,
It is checked whether or not there is any trouble, and the maximum fundamental frequency BHZ (FIG. 4) at which no trouble occurs is set for each product M.

When two or more types of items M are present in the packaging device 1 and the supply conveyor device 2, the driving motor is adjusted in accordance with the basic frequency BHZ of the item having the smaller basic frequency BHZ in FIG. The number of rotations of M1 to MN is controlled.

FIG. 6 shows a second embodiment. In the second embodiment, a frequency determining unit 71e and a determining unit 71f are provided instead of the selecting unit 71a of the first embodiment in FIG. This discriminating means 71f is provided at each tray detection position P in FIG.
1, P2... P5, the commodity detection signals a2 to aM from the tray detectors S1 to S5 in FIG.
The product detection signal a1 from the weighing conveyor 4 is input, and it is determined whether or not the tray T exists in a predetermined section from the supply conveyor device 2 to the laminating machine conveyor 5a in FIG. 1, and the determination signal b in FIG. Output to the frequency determination means 71e. In other words, the discriminating means 71f is configured to detect the tray T at the downstream position P1 of the cutting stopper in FIG. 1 and then within a predetermined time after the tray T is detected at the label attaching position P5, If the next tray T is not detected at the downstream position P1, the tray T is moved from the downstream position P1 of the cutting stopper to the label attaching position P5.
Is determined not to exist. Note that, in the case of this embodiment, the predetermined section is set to a section from the downstream position P1 of the cutout stopper to the label attaching position P5.

In FIG. 6, the frequency determining means 71e
Has a slowdown value storage means 71g. This slowdown value storage means 71g stores the predetermined section P1
P5 (FIG. 1) stores the slowdown frequency corresponding to the set rotation speed of each of the drive motors M1 to MN when the tray T does not exist. This slowdown frequency is set to a value smaller than the basic frequency BHZ.

When the tray T exists in the predetermined sections P1 to P5 (FIG. 1), the frequency determining means 71e outputs the basic frequency BHZ as it is to the frequency calculating means 71c as the determined value DHZ. Therefore, when the tray T exists in the predetermined sections P1 to P5 (FIG. 1), the motor controllers MC1 to MCN rotationally drive the drive motors M1 to MN based on the basic frequency BHZ corresponding to the type of the item. The cycle time of packaging can be shortened, and the product M can be packaged without any trouble.

On the other hand, when the tray T does not exist in the predetermined sections P1 to P5 (FIG. 1), the frequency determination means 71e determines the slowdown frequency stored in the slowdown value storage means 71g as the determination value DHZ. Is output to each frequency calculating means 71c. Therefore, the predetermined sections P1 to P
5 (FIG. 1), if the tray T does not exist, the motor controllers MC1 to MCN use the stock conveyor 2 based on the slowdown frequency lower than the fundamental frequency BHZ.
1. Since the drive motor MJ of the supply conveyor 23 and the weighing conveyor 4 is driven to rotate, machine wear, noise, power consumption, and the like can be reduced.

By the way, by combining the processing capacity control devices 7 of the first and second embodiments, as in the third embodiment shown in FIG.
1a, a frequency determination unit 71e, a slowdown value storage unit 71g, and a determination unit 71f may be provided. In the third embodiment and the second embodiment of FIG. 6, the other structure is the same as that of the first embodiment, and the same or corresponding parts are denoted by the same reference numerals and description thereof will be omitted.

FIG. 8 shows a fourth embodiment. In the fourth embodiment, the selection means 71al is provided with an unsteady value storage means 71gl.
It has. The unsteady value storage means 71gl stores an unsteady frequency (unsteady value) corresponding to the unsteady rotation speed of each drive motor of the supply conveyor device 2, the lifter 10, and the folding members 15, 16 (FIG. 2) in the unsteady mode. I remember. The selection unit 71al receives the mode signal b1 of FIG. 8 instead of the operator value Op of FIG. 4, and outputs the frequency calculation unit 71c as it is as the selection value SHZ in the case of the steady mode.

On the other hand, in the case of the non-stationary mode, the selecting unit 71al compares the non-stationary frequency stored in the non-stationary value storage unit 71gl with the basic frequency BHZ. Value and select the value S
HZ is output to each frequency calculating means 71c. The other configuration is the same as that of the first embodiment of FIG. 4, and the same or corresponding portions are denoted by the same reference characters and detailed description thereof will be omitted.

Therefore, each of the motor controllers MC1 to MCN shown in FIG.
Drive frequency β determined by HZ and frequency ratio α1 to αN
The number of rotations of each of the drive motors M1 to MN is controlled based on 1 to βN. On the other hand, each of the motor controllers MC1 to MCN
In the unsteady mode, when the fundamental frequency BHZ and the unsteady frequency are different from each other, the smaller value and the frequency ratio α
The number of rotations of each of the drive motors M1 to MN is controlled based on the drive frequencies β1 to βN determined by 1 to αN.

Here, the unsteady mode refers to, for example, an initial operation after the power is turned on, or a mode in which each drive motor is reversed to return to the origin after trouble occurs, and the unsteady frequency (value). Means the number of rotations of the motor set in these modes.

In each of the above embodiments, the fundamental frequency BHZ
Was determined for each item determined by the type of product and the type (size) of the tray as shown in FIG. However, whether a product falls or falls in a tray is generally not much different from the size of the tray.
Therefore, the basic frequency BHZ may be determined only by the type of the product regardless of the type of the tray. By doing so, the registration procedure of the fundamental frequency BHZ is simplified.

Further, in the above embodiment, the basic motor frequency BHZ is multiplied by the frequency ratios α1 to αN shown in FIG. 5B to set the rotation speeds of the drive motors M1 to MN.
The frequency corresponding to the number of rotations of each of the drive motors M1 to MN
It is not necessary to register every MN, so that the registration procedure becomes easy. However, in the present invention, each of the drive motors M1 to M
The basic frequency BHZ may be set for each N.

Further, in each of the above embodiments, the supply conveyor device 2, the packaging device 1, the direction change conveyor 3, the weighing conveyor 4, and the laminating machine conveyor 5a of the packaging and pricing device shown in FIG.
Of the drive motors M1 to MN are reduced. However, after the product M is wrapped with the film F, troubles are unlikely to occur, so the speed of only the supply conveyor device 2 and the wrapping device 1 may be changed.

Further, in this type of packaging apparatus 1, a pressing roller for pressing the bottom surface Tb of the tray T is often provided above the sealing apparatus 19 in FIG. 2. In this case, the number of rotations of the driving motor of the pressing roller is also reduced. Control is performed in the same manner as the pusher 13. Further, in each of the above embodiments, the tray T is detected at the position P1 downstream of the cutting stopper 22, but the tray T may be detected at the position upstream of the cutting stopper 22.

As described above, according to the invention of each claim, the processing capacity for wrapping a product with a film at the wrap station is changed according to the type of the product or the type of the product and the type of the tray. The packaging speed of the equipment can be set to an appropriate speed for each type of product or each type of product and tray. Therefore, it is possible to prevent the unpackaged product from falling or spilling in the tray, and it is possible to shorten the cycle time of packaging.
