Description

Detailed Description of the Invention (Industrial Application Field) The present invention automatically converts packaging conditions according to various bag dimensions without manual work when supplying bags and filling them with items to be packaged. The present invention relates to a device designed to do this.

(Prior art) When the bag dimensions are changed in a bag supply type automatic packaging machine for packaging foods, medicines, etc., it is necessary to adjust the various packaging elements to match the bag concerned. Every time the bag dimensions change, each part is manually adjusted.

(Problems to be Solved by the Invention) Therefore, it takes a lot of time and is inefficient, and troubles occur due to uneven settings and adjustment mistakes in adjusting various elements.

In particular, in recent years, the contents of packaging have become more versatile due to high-mix, low-volume production. This has resulted in an increase in the number of adjustment points and the number of adjustments required on machines, which significantly impedes productivity. Since the adjustment is made using the same tool,
There are also problems in the safety and health departments.

The present invention aims to solve the above-mentioned problems by electronically controlling the changes and adjustments of various elements according to the bag size, and by outputting the output to each operation source, the setting operation can be performed quickly and accurately. The aim is to dramatically improve work efficiency.

(Means for Solving the Problems) In order to achieve the above object, the present invention has the following configuration, that is, one sheet is taken out of the packaging bag to be used and it is placed inside the frame of the reading device. a reading means for reading the table dimensions using a sensor disposed movably within the frame; a preset memory for storing operation data of the packaging machine corresponding to the dimensions in advance; and an input means for inputting the operation data; It is characterized by comprising a mechanism control means for controlling various elements based on operation data from the read bag dimensions.

In this case, the control of various elements includes setting and changing the timing of starting and stopping, and changing the amount of acceleration/deceleration operation of the speed.The present invention will be specifically explained below with reference to examples.

(Embodiment) FIG. 1 is an overall perspective view of a reading device constituting reading means in the present invention. Reference numeral l denotes a rectangular frame body for storing Sa for measurement, and the bottom plate 2 is slightly inclined toward the force on each side of the vertical and horizontal frame pieces. Due to its own weight, it slides inside the bottom plate 2 and matches the reference end faces X and Y (see Fig. 2) for surface dimension measurement.

Reference numerals 3 and 31 denote bag size detection sensors 'ys-p-'c disposed on opposing surfaces where the reference end surfaces X and Y are formed.
-t=7, -, 'W and dimension length among different dimensions are read, and specifically, this is done with the following configuration.

4.4' is a support rod that supports each sensor 3.3', and is not attached to movable plates 5 and 51. Each movable plate 5.5' is a reference end surface for measuring the bag dimensions. It is screwed together with a screw shaft 6.6f located outside of the X and Y directions and parallel to these. 7 and 1 are motors with reduction gears for rotating each screw shaft 6.6', and by reciprocating the movable plate 5.5I by forward and reverse driving of each motor 7 and γ, the frame l is rotated.
In the illustrated example, the sensor 3 measures the width W when the motor 7 is driven, whereas the sensor 3 measures the width W when the motor 7 is driven. The sensor 31 measures the length dimension. Note that 8 and 8' are guide rods for stably moving the movable plates 7 and 71, and 9a and 9b, 10a and 1 (u is a bracket protruding outward from the frame body,
11 is a confirmation sensor that detects the presence or absence of ya in the frame 1.

In the above embodiment, the bottom plate 2 of the frame l is formed into a double bottom,
A large number of air blow-off holes are provided in the upper base, and compressed air is blown out from the holes so that the Ba
can be set to the reference position smoothly and in a short time.

Next, to explain the operation, when one of the bags is taken out of the packaging bag and put into the frame l having the above structure, the bag a slides on the bottom plate 2 and the standards X and YK are aligned, but at the same time When the confirmation sensor 11 is activated, the motor 77' is driven in a predetermined sequence, and the IC is moved so that the bag size detection sensors 3 and 31 detect the position of the end face opposite to the reference end faces X and Y of ya, and the bag size is determined. is read and output to the central processing unit (computer CPU).

Therefore, the central processing unit outputs to various elements from a preset memory in which operation data corresponding to various table dimensions are set and stored in advance.

Hereinafter, to explain this, FIG. 3 is a functional block diagram of the present invention, and FIG. 4 is a schematic diagram of the entire apparatus of the present invention, in which a reading device having the above configuration is disposed at a predetermined position of the packaging machine 12, One sheet a of the packaging bag 13 to be used is placed into the frame 1 of the reading device. Then, the confirmation sensor 11 is activated, the motor 7 and γ are driven, and the bag size detection sensors 3 and 3I read the ya size and output it to the central processing unit 16 (CPU).
(CPU) reads the bag a from the preset memory 17.
The operational data of the various elements is extracted and processed, and the mechanical means of the various elements are controlled based on the operational data of the various elements.

In order to store the operation data in the preset memory 17 in the present invention, the operation data for every 8 dimensions is inputted by the input device 14, and the data is sequentially stored in the reset memory 17. The various elements are a plurality of means that require conversion adjustment when the bag dimensions of the packaging machine 12 are changed (opening degree of the pair of bag gripping arms, printing position M2, filling amount M3, sealing temperature M4, vacuum pressure) MS, rotary table speed M6, etc.), and these means may be different depending on the model, function, etc.

An outline of each of the above means will be described below.

■ Opening degree M1 of the front gripping arm pair The opening degree of the pair of arms that are incorporated in the rotary pull body and which grip and convey the packaging bag is changed according to the inside of the bag W.

■Date printing device This device prints the date at a predetermined position on the pigeon packaging bag 13, and the position is controlled according to the size of the bag.

■Filling amount M3 This is to control the filling content corresponding to the packaging bag 13), and the filling may be a single substance such as gas, liquid, viscous material, powder, solid, etc., or a combination of two or more of these. It is a mixture.

■Seal temperature M4 Controls the amount of heater heating when using a heat-adhesive film bag.

■ Vacuum pressure M5 When performing vacuum packaging, the vacuum pressure in the vacuum chamber is controlled depending on the packaging bag.

■Table rotation speed M6 The packaging processing capacity is controlled according to the packaging bag.

(Effects of the Invention) As shown in FIG. 4, the present invention allows operation data corresponding to the size of the bag to be output from the preset memory 17 by simply taking out one sheet a from a packaging bag and placing it in the frame 1 of the reading device. Therefore, the adjustment work of the various elements of the packaging machine 13 is automatically performed. Therefore, changing the packaging conditions, which was conventionally done manually, can be done quickly and accurately, improving work efficiency.
