The tape 5 (Fig. 4) has a protruding part.

The packaging machine l has two opposing L-shaped cross-section supports If7.
(Fig. 44), on which the paper chip 5 is supported and a flange 8 is formed which passes through the fin 6' that protrudes downward. Drive wheel has 9-karat gold,
This engages with the grooves of the fin 6 and both edges 4t-
Mix the coals together and slide the support member 7 over the soft tape 5t with a device that pulls it with a longitudinal force of 1.

Immediately before the paper tube 5 formation site, a package is placed in the tube 5.
A conveyor system (fl
The rear end of lO is arranged It. The article 11 is forced into the paper tube 5 by the blade 12 of the conveyor 10 at a speed approximately equal to the speed of the paper tube 5 . The extruded vlJ product is sent to the lower layer of the paper chain 5 in the longitudinal direction.

The packaging machine 1 has a pair of transversely abrasive cutting and joining grooves near its rear end through which the paper chain is threaded.

The stomacher 13 cooperates to draw between the articles to join the upper and lower walls of the paper tube and to separate the article from one to the next.

J* 13 is formed of a rotating S member including one or several arms (only one arm is shown in FIG. 3), and the tip of the arm is the operating end. 21 hard ji wr 13 f'FI1m 0 ji where the slow circular trajectory of part 4 is almost in contact with the top and bottom of Naeve *
Is the twisting action of the paper tape by 13 and lIA moving 9 by heat sealing? In the case of joining the hoe 4L/) to form the 0 fin 6, which can be joined, it can also be done by crimping when cold with the driven wheel 9. The article package 14 (formed in the form of a tablet) shown in FIG. The fins 6 of the pipe 5 are separated by the above-mentioned cutting, and have skin fins 16.

In Figure 2, the fin 16 is wrapped around f! - folded along the lower surface II - can also be folded down and placed on the market in this state.

As shown in Figure 3, the packaged articles assembled and cut by N-13 are conveyed by a conveyor device 17 located at Ii#M.

The above-mentioned type of package t JFC Shin machine μ fin seal packaging machine is widely used in the industry. Conventionally, this type of packaging machine has two types: JFC-13, conveyor cap 1110 ten-chapter 5 By the same electric motor that drives the drive-9 that pulls the phosphorized v4 node l81J so that the motion of the jim13 during one revolution is not constant
III through a powerful mechanical transmission system.

11g During one rotation, the velocity of m-13 is t-must be 4J,
Firstly, the length of the circular trajectory of the working light #1 of the zigzag-13 is the unit length between the lateral cuts of the fins 15 of the package. They generally do not match (even if they roughly match the items they consist of, they will not match for items of different lengths). Second, Ji1-1
The working light 4s of No. 3 must enter the working area to perform joining and cutting at a speed Wf that is substantially higher than the transport speed of the paper chain.

Jiw Non-uniform luck for 13! The mechanical transmission Isophosphorus used in conventional packaging + IA machines is extremely cumbersome because the movement of the compressor is adapted to the length of the article. Then, each time the items sent to the packaging machine change, the operator says: According to the present invention, as shown in FIG.
3 is driven by @l electric motor 18 and paper chain 5
The next drive wheel 9, which pulls
The paper strip 2 subordinated to the motor 20 is made of a different material than itself or has markings 19 of a different color;
The mark 19 is spaced and delayed on at least one of the edges 4. The mark 19 is no different from the mark 21 appearing on the fin 6 of the paper chain 5.The packaging machine has a sensor that detects the passage of the mark 21. A sensor 22Fi, consisting of a photoelectric lightning 22 (FIGS. 3 and 5) receiving an element g1 from a device 23, determines the speed of the first motor 18 according to the law V according to the arrangement of the marks 21 on the fins. In order to change the IIJ bond-q, which is a function of the frequency of mark 21 readings,
In the example shown in FIG. It is considered to be a non-uniform array. Furthermore, this arrangement is repeated in the same way for each section of the paper strip corresponding to one (ro) rotation of the di-13, so that the speed of the motor is varied according to the law added during one revolution of the di-13. In the lower part of 0m81, which has become more Ji-gaichi 1
The O arrow F in which 3 is schematically omitted indicates the direction of rotation of the dicarbonate, and V indicates the circumferential speed of the distal tip portion following the circular locus marked by the stroke #t.

By arranging the mark 21 as shown in the isB diagram, a change in the pI@ velocity of the tip as shown in FIG. 8 is obtained. In this diagram,
At time t1, the wire w-13 is stretched in the working state, that is, joined and cut w.
0 time 1. indicates when 1 is in the position of decay. is Jim
13 is in a position that is the same diameter opposite to the operating position, and time t is the time when the motor rotates once from this position. Therefore, the time (electronic to) is calculated by the time taken for one rotation of the paper chain 0, and . It is also possible to provide the fin 6 with marks of different alignments.For example, the marks 21 arranged as shown in FIG.
In addition, marks 24 (FIG. 8) can be provided on the fins 6 at regular intervals. In this case, mark 24'ft
A second sensor is required to read 1c. This sensor is useful for generating the speed of the paper tube, that is, the speed of the second motor 20.
Not only can the speed of the second motor 20 be changed as described above, but also the speed of the second motor 20 can be made to follow the fluctuations in the speed of the second motor 20. It becomes like a monkey.

To explain in more detail, 21 as shown in FIG.
! ! By providing marks 21 and 24 of ,
However, if the angular velocity ω, 0 of the second motor 20 changes as shown in Fig. 1i147A, The speed V of the seal is varied so as to follow the curve in Figure 7B.
The curve in FIG. 7B is a combination of the speed change law shown in FIG. 6B and the change caused by the speed fluctuation of the second motor 20.

Therefore, IiA is moved so as to have a non-uniform conduction, and at the same time, if there is a speed fluctuation in the paper, it will follow it and the law of speed change of Joe will be 0. ? ! In the packaging machine according to the present invention, as shown in FIG. ! For each length of 1vA specific to the article, the law of commuting is added, so that the strip of paper is quasi-vIl with the arrangement of marks 14->7 for the length of the article. However, the printing and design of the paper strips differ depending on the product! It is common to use time-saving paper strips for # items, so
The above is not particularly helpful.

As is clear from the above description, the packaging machine according to the present invention has a W4 structure with a capacity of 41 m compared to the conventional machine.
11 is omitted, it becomes faster and there is no need to operate the transmission MJ Iso to adjust the movement of the gee every time the length of the article changes. As explained above, the 7-stem according to the present invention has the advantage that, for example, when the speed of the first motor is oscillated with the second motor and the force is 1, the 2!! of the ml motor is related to the speed of the second motor. It has wide applicability and can be used when it is desired to make the first motor subordinate to the second motor, such as when the motor is controlled according to a predetermined law.
A general overview of the system according to the present invention is shown in FIG. 9. Referring to FIG. 9, Ml indicates a slave motor, and Ml represents a master motor. Motor M is a longitudinal direction. For example, marks arranged uniformly with the mark 21 described above (not shown)
25 t of strings with attached strings are driven in the same way along the length.

The passage of the mark on +7 1 is detected by the reading device 26 mounted on the control panel 1127.
FJIJ04) The device remembers the output signal of the reader 26 and reads the marks in order to change the speed of the motor Ml according to the arrangement of the marks on the strip and according to the added law of 4f in correlation with the speed of the motor M. It is configured to send the J@ number, which is the @ number of the frequency, to the motor M1.

As is clear from the above explanation, the basic idea of the present invention is to apply fT to the string driven by the master motor.
Marked? I: The feelings served by reading @t
- By sending the signal to the subordinate maple motor, the two motors are forced to wait for a subordinate relation. A-sama and Kizuna Nobunari of the above embodiment can be varied widely.
