DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stretch film stretched over a wrapping portion, and the product is pushed up, and then the left and right and rear ends (or front ends) of the film are folded into the bottom of the product. When the product is taken out of the packaging section, the front end (or the rear end) of the film is folded into the bottom of the product for packaging, and the package after packaging is completed is pushed out of the packaging section with a pusher. Related to the device.

[0002]

2. Description of the Related Art A packaging and pricing apparatus conveys a product from a carry-in portion to a portion below a packaging portion, pushes up the product from below on a film stretched horizontally on the packaging portion, and covers the surface of the product with a film. Further, after folding the left and right and rear end portions (or front end portions) of the film into the bottom of the product with the left and right folding plates and the rear folding plate (or the front folding plate), when the product is carried out of the packaging portion by the pusher, the film is removed. The front end (or the rear end) is folded into the bottom of the product, and a label is applied to a predetermined position of the product after packaging. And a label is attached to a product being carried out by a pusher as proposed in Japanese Utility Model Laid-Open No. 3-126807.

[0003]

The speed at which the product is conveyed by the pusher is determined by the ability to fold the front end (or the rear end) of the film without hindrance and the processing speed of the apparatus. For this reason, in a device having a high processing capacity, it is necessary to apply a label to a commodity moving at a considerably high speed.
Also, as a means for applying a label, a pressing method that can more reliably perform label application has recently been adopted as compared with a method in which a label is conventionally sprayed and applied to a product by air. This pressing method
The label is attached by pressing the label suction surface for holding the label by suction against the product. In the case of this pressing method, if the moving speed of the product is high and the moving force is large like a pusher conveyor, when the label suction surface is pressed against the product, the film is pulled by the suction surface to wrap the product. There is a problem that wrinkles are formed on the film or the film is torn. For this reason, conventionally, in order to perform label sticking without any trouble, the conveying speed of the pusher must be reduced, and the processing speed of the apparatus is sacrificed accordingly.

[0004] The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object the following.
Even if the labeling method is a press-type labeling method, a packaging and price providing device that can perform labeling satisfactorily without substantially sacrificing the performance of the device such as reducing the processing speed is provided. Is to do.

[0005]

In order to achieve the above-mentioned object, the present invention provides a technical means in which a pusher for discharging a packaged product from a packaging section has a product discharge speed from the start of discharge to the end of discharge. In this case, the switching is performed in the middle of the process, the unloading speed on the unloading end side is made lower than the unloading speed on the unloading start side, and a label is affixed to the product being transported at the low speed. Further, in addition to the configuration in which the labeling is performed while the unloading speed is switched from high speed to low speed and the unloading is performed at a low speed, the driving of the pusher is temporarily stopped halfway from the start of unloading the product to the end of unloading, and during the stoppage A label may be attached to the product, and after the label is applied, the pusher may be restarted.

[0006] At the time of the above-mentioned switching of the unloading speed of the pusher and the temporary stop of the driving of the pusher, at least the front end (or the rear end) of the film covering the product by the transfer of the pusher starts to be folded into the bottom of the product. Later. In addition, the label is not limited to the conventional method of applying and blowing a label with air, and the label adsorbing surface of the label applying device that holds the label by suction with the adhesive side of the label on the bottom is used for the product. A pressing method in which pressing is performed may be used.

[0007] Further, the timing for switching the discharge speed of the pusher or the timing for temporarily stopping the driving of the pusher is a detecting means for detecting that the product has been discharged to a predetermined position on the discharge path of the product by the pusher. Is established,
The transfer speed of the pusher is switched or the driving of the pusher is temporarily stopped based on a product detection signal from the detection unit. Furthermore, in addition to the above-described configuration in which the switching time of the unloading speed of the pusher or the timing of the suspension of the driving of the pusher is performed by detecting the unloading position of the product, the position of the pusher for transporting the product is detected. It may be performed.

[0008] The packaging and pricing apparatus to which the present invention is directed is
The configuration of the packaging machine and the label attaching device is not limited as long as the pusher is used to carry out the packaged product from the packaging unit at the packaging unit. For example, a packaging machine of a type that moves the elevator head in the horizontal direction after receiving the product placed in the product loading section by the elevator head may be used. Further, the label sticking apparatus may be configured as a unit with the label printer, and the label sticking apparatus may be of a type in which the label sticking is performed by vertically moving or rotating the label suction surface.

According to the above configuration, the packaged product is discharged from the packaging section by driving the pusher, but the speed of the pusher for carrying out the product is switched from high speed to low speed, and the product delivered at the low speed is switched to the low speed. Since the label is applied, even if the label applying apparatus is a pressing method, wrinkles do not occur on the film for packaging the product and the film is not torn. Of course, if the labeling method is a conventional air blowing method, labeling can be reliably performed without causing damage such as wrinkles or breakage on the film. In addition, by temporarily stopping the drive during the unloading without switching the speed of the pusher for unloading the product, and attaching a label to the unloaded product, the packaging film can be moved to a predetermined location without damaging the packaging film. Labels can be securely attached.

The switching of the speed of the pusher for carrying out the product or the temporary stop of the driving of the pusher is performed by detecting means for generating a label sticking signal, that is, in the case of performing label sticking on the basis of the front end, the outlet path of the product. The detection is performed based on the detection result of the detection unit that detects that the product has been carried out to the predetermined position, or the detection unit that detects that the pusher is positioned at the predetermined position when performing labeling based on the rear end. .

FIG. 7 shows the electrical configuration of the above-described apparatus, which includes a weighing label printer control unit D and a packaging mechanism control unit E. The weighing label printer control section D mainly controls weighing label printers,
Controlled by U28. The packaging mechanism control section E mainly controls the mechanical section of the packaging machine, and is controlled by the CPU 37. Next, the weighing label pudding controller D will be described.
An AM 30, a display / operation unit 31, a measuring unit 32, a communication interface circuit (INF) 33, a printing unit 34, a suction unit driving unit 35, and a product detection sensor 36 are connected. A program is stored.

The RAM 30 has an area for registers and flags used when the CPU 28 executes the control program of the ROM 29, and a preset data area in which various data are stored in advance for each product. In the preset data area, data for price calculation and label printing, such as "article name (article name) such as pig (peach meat)" and "unit price such as 250 (250
"Circle)", "tare, e.g., 5 (tray weight: 5 g)", and "label direction, e.g., (1)" which is data for label attachment are stored in advance. Here, there are three types of label orientation data: (1), (2), and (3). (1) ... the orientation when the label was issued (2) ... when the label was issued Orientation + 90-degree rotation in counterclockwise direction (3) ... meaning when the label was issued + 90-degree rotation in clockwise direction.

The display operation section 31 has an operation section composed of a keyboard and a touch panel, and a display section composed of a liquid crystal display of a dot type, and inputs various data and commands or inputs data based on commands from the CPU 28. , Preset data, and various messages, and is also called a console unit. The weighing unit 32 supplies a weighing signal of the product placed on the product placement unit a to the CPU 28. Communication interface circuit (I
NF) 33 is a circuit for exchanging various data and commands with the packaging mechanism control unit E. Data to be exchanged will be described later. The printing unit 34 is a weighing label printer, equipped with a thermal printer, and prints the product name, price, unit price, effective date, bar code, etc. on the label based on the instruction of the CPU 28,
The printed label is issued to the issuing port 7.

The suction unit driving unit 35 (the driving mechanism C2) includes:
After moving the label adsorbing section C1 to adsorb the label F in the issuing port 7, it is moved to a predetermined label attaching position, and the direction of the label adsorbing surface is set to a predetermined direction. Is a mechanism for affixing a label in a predetermined direction to a predetermined position of a product by lowering the label at a predetermined timing. The commodity detection sensor 36 generates a signal for attaching a label, and when the commodity is located at the label attaching place, supplies the fact to the CPU 28.

Next, the packaging mechanism control section E will be described. The CPU 37 has a communication interface circuit (INF) 38, a ROM 39, a RAM 40, an operation unit 4 via a bus 37a.
1, and the mechanism drive unit 42 are connected. The communication interface circuit (INF) 38 is a circuit for communicating various data and commands with the weighing label printer control unit D.
The data to be exchanged will be described later. ROM39 is CP
A control program executed by U37 is stored. RA
M40 includes various tables and the like for determining control data based on the shape data (length, width, height) of the product in addition to various registers and flag areas used when the CPU 37 executes the control program of the ROM 39. It is remembered.
The operation unit 41 is a switch for starting and stopping the apparatus. The mechanism drive section 42 is a circuit for driving each mechanism section of the packaging machine when packaging is performed. Specifically, the mechanism drive section 42 includes a motor 43 for driving the elevator 2, a carry-in motor 44 for the conveyer 1 for carrying in goods, and a film. Motor 45 of transport mechanism A3, left and right folding plate A for folding the left and right ends of the film into the bottom of the product
5, a drive motor 47 for opening and closing the film, a drive motor 47 for operating the folding plate A6 after folding the rear end of the film into the bottom of the product, and a product with the left, right and rear ends of the film folded out of the packaging unit. There is a drive motor 48 for moving the pusher A7 forward and backward.

The data and commands transmitted and received between the weighing label printer control unit D and the packaging mechanism control unit E relate to the present invention because the weighing label printer control unit D sends the data to the packaging mechanism control unit E on the weighing pan. When the weighing of the placed product becomes stable, C
PU 28 → interface circuit (INF) 33 → interface circuit (INF) 38 → CPU 37 sends a signal to that effect from label printer control unit D to packaging mechanism control unit E, and activates elevator motor 43 and carry-in motor 44. When the elevator motor 43 is started, a pulse is generated by the rotary encoder 49 and counted by the CPU 37. The label printer controller D calculates the price from the weight of the product and prints it on the label. And
After the printed label is sucked by the suction unit, the label is transferred to a predetermined sticking position. The packaging mechanism control unit E drives the film transport motor 45, the left / right folding plate drive motor 46, the front folding plate drive motor 47, and the pusher drive motor 48 based on the count value or the detection content of various sensors.

There are two types of control of the pusher drive motor 48: a case where a label is attached based on the front end, and a case where a label is attached based on the rear end. In the case of the front end reference, when the product detection sensor 36 detects a product, the CPU 28
Drives the suction unit driving unit 35 to lower the label suction unit to apply the label, and transmits the fact to the CPU 37 of the packaging mechanism control unit E. The CPU 37 switches the driving speed of the pusher when it receives it, or stops the driving of the pusher. When the driving of the pusher is stopped, the CPU 28
→ The pusher is restarted by the label sticking completion signal transmitted to the CPU 37. In the case of the rear end reference, the CPU 37 switches the driving speed of the pusher when the flag attached to the belt to which the pusher is attached is detected by the sensor installed at the predetermined position to reach the predetermined position. Or stop driving the pusher. At the same time, CPU 37 → interface circuit (INF) 38 → interface circuit (INF) 33 → C
The fact is transmitted to the CPU 28 on the path of the PU 28. As a result, the CPU 28 drives the suction unit driving unit 35 to lower the label suction unit and attach the label. When the driving of the pusher is stopped, the pusher is restarted by the label sticking completion signal transmitted from the CPU 28 to the CPU 37 as in the case of stopping the driving of the pusher in the case of the front end reference. Incidentally, the position detection of the pusher in the case of the rear end reference is not limited to the above-described configuration in which the flag attached to the belt to which the pusher is fixed is detected by a sensor, but means for detecting the position of the pusher by a count value. But it is possible.

Next, the outline of the operation of the above-described apparatus will be described with reference to the flowcharts of FIGS. It should be noted that the flowchart shown in the figure is not a strict description of the control executed by the CPU, but is an explanatory flowchart describing a portion related to the drive control of the pusher A7 in the control executed by the CPU. [I] Speed Switching (See FIG. 8) (Start): When the count value of the pulse generated by driving the elevator motor 43 reaches a predetermined value, the following process is started. (SA1) ... The pusher is driven at the first speed (high speed). As a result, carrying out of the product from the packaging unit is started. (SA2)... It is determined whether or not the product carried out by the pusher is located at a predetermined position (based on the front end) or whether the pusher is located at a predetermined position (based on the rear end). It should be noted that whether the label is to be stuck on the basis of the front end or whether the label is stuck on the basis of the rear end is set in advance. For example,
The PLU file is preset together with the unit price, product name, and tare data for each product number. If the determination by the detecting means is not "YES", the step (SA) is determined to be "NO".
The processing of 2) is periodically repeated, during which the CPU is executing other processing necessary for packaging control. (SA3) When the determination result of (SA2) is "YES", the pusher is driven at the second speed (low speed). The second speed is reduced to approximately half the speed of the first speed. At the same time, a label attaching command is issued, and the second
The label is attached to the goods carried out at the speed of. (SA4) ... It is determined whether or not the product has been unloaded by the pusher. This determination is made by detecting whether the pusher is located at a predetermined carry-out position by a sensor. (SA5) When it is detected that the pusher is located at the predetermined unloading position, the pusher is driven in the reverse direction to return to the initial position (detected by the sensor) to prepare for unloading of the next product. (End)… Ends pusher drive control processing.

[II] Case of temporarily stopping (see FIG. 9) In this case, (Start), (SB1) and (SB2) are (Start), (SA1) and (S1) in the case of [I] described above.
Same as A2). (SB3) When the judgment of (SB2) is "YES",
Stop driving the pusher. (SB4)… Judge whether label sticking is completed (Completion of label sticking is detected by a sensor that detects that the suction surface of the label suction portion C1 has come into contact with the product, and an upward force is applied to the label suction portion. Is detected that the upper parallel arm is separated from the supporting arm by adding more than a certain amount). When label attaching is completed, a signal indicating completion is transmitted from the weighing label printer unit, and it is determined whether or not the signal is received. (SB5) ... Restart the pusher. (SB6) Same as (SA4) for [I]. (SB7) Same as (SA5) for [I].

In the above-described embodiment, a case has been described in which the timing for driving the pusher or the driving speed is constant irrespective of the product, but it may be changed according to the size of the product. For example, when the vertical width of the product is long, the drive timing is delayed and the drive speed is reduced.
The size of the product may be detected by the product placement unit or may be preset in advance. Further, the packaging and pricing apparatus to which the present invention is directed is usually for weighing, packaging, printing a label, and affixing the printed label to the packaged product (weighing / packing / pricing mode). For automatic application). However, the device itself has other modes: (a) When labeling is manually performed (manually applying in weighing, packaging, and price mode) Labeling of special products or emergency operation when the labeling device breaks down Measures. (b) When only packaging is performed and no weighing is performed (packing mode) (c) When only weighing is performed and packaging is not performed (weighing /
Priced mode) and used in each mode as needed.
In such a case, the present invention is to solve the problem of automatically applying the label, and in the case of the mode other than the automatic application of the label (the above (a) and (b)). In this case, there is no problem even if the pusher is driven in the same manner as before. Therefore, it is preferable that the speed of the pusher is switched and the stop is performed only when the operation mode of the weighing / packaging / pricing device is set to the mode in which the label is automatically applied. Further, in the above-described embodiment, the case of the weighing / packing price valuing device is described, but a fixed price wrapping price adding device without a weighing unit may be used.

[0031]

According to the first and second and third aspects of the present invention, the labeling apparatus according to the present invention performs labeling while moving or stopping at a low speed. Even with the device, the label can be satisfactorily applied without wrinkling of the film or tearing of the film. In addition, the pusher operates at a normal speed (high speed) except for a very short period of time when the label is applied just before the end of the product unloading, and the unloading speed of the pusher is set to a low speed from the beginning to the end. As compared with the case, the characteristics such as the processing speed of the apparatus are not substantially sacrificed. Further, when the product is completely carried out by the pusher, the labeling is completed, and there is no need to provide a dedicated labeling station on the downstream side of the carry-out path by the pusher, so that the entire apparatus can be downsized.

According to the configuration of claim 5, the label can be attached based on the front end of the product, and according to the configuration of claim 6, the label can be attached based on the rear end of the product.
The switching of the speed and the stop of the driving are performed by the signal for sticking the label, so that it is not necessary to separately provide a special detecting means for the switching of the speed and the stop of the driving.
