Description

[Detailed description of the invention] The present invention relates to a bag opening supply device.

Currently, relatively small parts such as automatic books and electrical products are produced in factories, then manually packed by workers into bags for a certain number of bags, and then shipped in cardboard boxes. There is.

However, since the bags used for this packaging are generally made of relatively thin synthetic degreased film, there is a problem in that it takes a lot of time and effort to open the bags, making it difficult to complete the process.

Also, when I went to a supermarket, etc., I had a similar problem when I was putting products in plastic film bags. Currently, the present invention is a self-service service for customers.The present invention was developed in response to the above-mentioned concerns, and the purpose of the present invention is to supply bags to workers in an open state. To achieve this object, the present invention provides a bag receiver, a bag fitting device for fitting a bag into the bag in an open state, and a bag opening supply device comprising eight bags. ＠ Since the present invention has the above-mentioned structure, the part fitted to the receiver is
Since the bag 7 is obtained in an open state, there is no need for one worker to open the bag, and the efficiency of the work can be improved accordingly.

The embodiments shown in the drawings will be described below.

In Figures 1 to 5, there are two bag receivers, and a tubular film is used to form the bag. The first factor is a front view, the second is a side view, the third is a plan view, and the fourth is a sectional view taken along line A-A in FIG.
FIG. 5 is a rear view. However, in order to avoid cluttering the drawings and to facilitate explanation, appropriate parts have been omitted and notches have been made.

Five support plates (5) (6) move symmetrically opposite to the block (4) which is rotatably supported at the center of the top plate of the support frame (8) fixed to (2c). ), the receptor (1) (1) consists of a frame, and the supporting plate (5) is attached to one bottom edge of the frame. ) One end is integrally formed.

Therefore, this receptor (1) (1) is - the support frame (

are rotated in opposite directions, and as a result, the film holding member #4) simultaneously rotates as shown in the imaginary line in Figure 1, and its cheek (295L) Receptor (1
] and becomes sticky. However, the reason why this air cylinder operates is as described below.
This is when the guide frame (6) has descended to just above the receiver (1).

In fact, this spoon]′? ￥ member) by receptacle (1)
This is what happens when you can hold the film between the two.

The structure of this embodiment has been explained above. In Figs. 1 to 3, (2) is a mounting plate that is attached to the support plate (8) so that it touches the large plate of the frame (6) by 5tc. Limit switch,
- is also a kite frame solidified on a large plate (also not shown)
(e) A solenoid valve, and a plurality of timers (1) and (4) to properly control the operation of the solenoid valves (4) and (4), a timer (π) to control the operation of the heater, a 2nd timer, and a solenoid valve. , a heater, a circuit for electrically connecting a limit switch (1), and a starting switch inserted into this circuit and mounted in a suitable position other than the machine frame (2) or the like.

Now, let us explain the operating state of this embodiment.
First, the first worker positions himself in front of the receiver (1) and inserts a blank space below the start switch. ◎When the start switch is turned on, the air cylinder (9)
) is activated, the kite frame (6) is lowered, and the guide pieces a-q3 attached to the lower end of the kite frame (6) are moved to the openings located just on both sides of the round receiver (1). At this time,
Both images are sandwiched between guide pieces aa a'a, and the entire circumference thereof is surrounded by the lower part of the full-shaped film Q.

After a certain period of time (about 1 or 2 seconds) has elapsed after the air cylinder (9) was activated, the air cylinder is activated and the film holding member (to) rotates to release its head. (
29a)... is the notch part (to) of guide piece a3
is passed along with the corresponding portion of the cylindrical film a1, and is brought into close contact with the side surface of the receiver (1). Therefore, the cylindrical film (11) is clamped at four locations corresponding to the lower clamping member (c) by the clamping member (c) and the side surface of the receiver (1).

Furthermore, after a certain period of time, the air cylinder (9) is operated again while the lower part of the 1fIa-like film (11) is being held.
The guide frame (6) rises and returns to its original position. Therefore, the cylindrical film Ql is pulled out from above the guide frame (6), and as a result, the cylindrical film Ql is moved to the receiver ( The guide frame (6) is now stretched from 1) to the guide frame (6). The set switch (to) is activated and the air cylinder (IIQ barrel) of the heat seal and cutter device is activated. , the cylindrical film 4 is folded at the bottom at the corresponding position, then heat-sealed and cut above the heat-sealed part 1, so that the lower part becomes one bag body, while the upper part returns to its original state (the state shown in FIG. 1).

When this heat sealing and cutter operation is performed, the corresponding position of the cylindrical film 4 is squeezed inward, but the guide piece t1) (13) resists the spring on the hinge I. This work can be done smoothly because the heater can be swung inward by the timer 16 of the timer in the heater a field, and the air cylinder connection is activated again, and the clamping members 4 return to their original positions. It returns and the film is released from the sandwiched state.

Then, when the operator rotates the receivers (1) and (1'), the bag (a) fitted into the receiver (1) as shown in FIG.
is obtained.

Here, the operator only has to properly press the space between the openings of the bag (&) and insert the S item, such as an electrical product, into the frame of the receiver 1) from the top of the bag (&). By putting one part in, the bottom s (J) of the bag (a) falls into the frame of the receiver (1). If the start switch is turned on before starting the process, a new bag will already be fitted into another receptacle (1) by the same operation as before.

As described above, according to this embodiment, by fitting the bag onto the receiver (1), the operator does not need to open the bag, but furthermore, the parts placed in the bag are wrapped in cardboard. The following means can be used to eliminate the work of conveying
1) This conveyor transports cardboard boxes (43
The position control of the cardboard box can be easily performed by known means by simply transporting the cardboard box to a position below the receiver (1).

Although one embodiment of the present invention has been described above, the number of receivers (1) is not limited to two, but may be one or three, and the number of receivers (1) may be one or three. The fitting device is not limited to this. In any case, according to this embodiment,
The packaging work for the parts, which conventionally required 13 people, now only requires 5 people, and the thickness of the conventional bag film has been reduced from 25μ to 401μ to facilitate one opening! The required thickness was 10
It has the advantage that the thickness can be as small as μ.

Next, a second embodiment of the present invention will be described with reference to FIGS. 1 and 8.

In this embodiment, instead of using a cylindrical film as in the previous embodiment for the fitting device, each bag (b) is formed in advance as shown in FIG. (0
), which is formed into a continuous shape (1), and which is further rolled up. Such films are often provided for customers in supermarkets and the like.

In FIG. 1, 04 indicates the volume Ijjla-, .

(45 (45 is a pair of stoppers that are disposed below the winding roll 0 bar and can move in the horizontal direction, The film (44) that has been sent out can be clamped.

(aE9 (m) is a pair of suction members disposed further below at an appropriate interval, and the suction members (g) and (g) are arranged so that both can be moved horizontally and vertically. In addition, suction holes (not shown) are provided in the form of a plurality of suction holes or slits on the surface (46a) facing the film (46a) (46a) of the film (46a) of the suction member (4).
You can now get L.

(47) (47) is the receptor (1) (1'
), but it is deeper than the previous receptor (1).

Well, next #! To explain the operation of the above device according to Figure 8, as shown in Figure 1 (A), first the suction 7111s material (C) is
(The stopper moves horizontally, clamps and adsorbs the film 4 from both sides, and then moves downward.) At this point, the stopper (4 → (4) is open, so the 1
The film 1 is being smoothly pulled out from the take-up wheel 14 as the suction material (4f9 (g)) is lowered, but one perforation (0) of the film (44) is pulled out by the stopper (c) ( At the point when the stopper (c) (c) closes as shown by the imaginary line in the figure (a), the stopper (c) closes the film (c) above the perforation (e). Clamp and press the suction-1tIIs material (4f9(
As the film 64 is lowered, the film (4f) is cut from this perforation (0).Then, the adsorption member (g) (4f9) moves horizontally while adsorbing the film 64 from both sides and cuts it. Open the bag (b).

This state is shown in figure (b). After that, the suction member 7# (to) descends further) and the bag (1) is attached to the receiver (47) as shown in Fig.
)), the suction operation is stopped, the suction operation is returned to the original position, and the same operation is repeated.

In the above operation, the closing tinge of the stopper (c) can be easily obtained by detecting the lowering position of the stopper (c) using a phototube or the like. Also, in the state shown in (c), If necessary, a holding member similar to that of the previous embodiment may be provided below the suction member in order to improve the separation of the film from the suction member.

Furthermore, in this example, the winding roll used is not limited to the one mentioned above, but a bag with a handle printed with the store name etc. used in supermarkets etc. can be continuously rolled up in the same way as the one mentioned above. Alternatively, the receiver (47) is not limited to this, and for example, one of the side plates (
4711) so that the bag with contents can be easily taken out from there. Two embodiments have been described above, so in any case, the present invention is applicable to As a result, the bag is obtained in an open state, so there is no need for the operator to open the bag, and the efficiency of the work is improved accordingly.
