Description

DETAILED DESCRIPTION OF THE INVENTION The present invention i4. The present invention relates to a feeding method and device for cutting a roll of wrapping paper or the like into a part of a booklet strip to a predetermined length, and can be used, for example, as a wrapping paper feeding device in a packaging machine such as Chianti.

This type of feeding device W has a fast-moving cutting operation, and conventionally, it uses two blades (la) and ('lb) k.
LI the strip (A) to a predetermined length by opening and closing.
To cut and set the cutting length, a pair of rollers +2+ and +2+ are used to sandwich and send out the band B-' (A).
The rotation time and stop time are all set to a predetermined length and interval.

That is, the rotation time of rollers +2+, +2) is 4d.
The amount of transfer around that area becomes the strip feeding loss, and the amount of koneka 9J
It will be a long time. (For example, Japanese Patent Publication No. 56-49205) However, with the above-mentioned conventional cutting method and device, the band P4-(3)
Depending on the material of the strip, static electricity, difficulty in cutting, heat, etc. may cause the tip of the strip to stick to one of the knives (], a), and (lb) after cutting. Obstacles to progress are auspicious. That is, inconveniences such as paper jams occur.

This means that when the movement of the strip (A) is in the stop state II: t:: ,ll! , ! l'tsukishi-t Mllii'1

This is done in such a way that it is sent out a predetermined distance in the forward direction after being stirred once.

Even if there is, it will be maintained to the point where I\J's arrival is almost the same as in the past. Defense! 1-Come.

Next, 1 - Implementation of the invention of the force distribution method 0 and the theory about the invention of the device for direct use
I: 4) There is a method to solve the same problem as the invention q), and the technical means to do so is the operation of the cutter and 1! ′
The feed roller, which rotates at a predetermined timing, is interlocked with the output shaft (of the link gear mechanism of the four-barrel gear type), and the input shaft of this link gear mechanism is connected to the crankshaft (
The radius of the pitch circle of the first @ city was set to be slightly smaller than the crank length.

The second technical means of the present invention operates as follows.

When the input shaft rotates at a predetermined speed, the first gear fixed to the crankshaft revolves, and along with this, the second gear. The third gears revolve and rotate, respectively. [C] One question can be obtained by setting the four-joint three-gear machine frame, the crank length, and the hitch circle of each tooth 11 to a specified value, but the difference between the crank length and the first gear When the Sochi circle is longer than the '1' diameter, the output shaft rotates forward by a certain angle and then reverses during one revolution of the input l1llll.

Cuckoo's knife is ν'FImJ at the point of change in rotation direction! After the strip is cut, the strip is pulled back in the opposite direction by the reversal of a roller connected to the output shaft. As a result, the 4Q bond between the knife and the obi piece is unraveled, and the ancient capital returns to its initial state.

4. If 'I is 1 - 'IF+' from the device + d next special a]
This movement is smooth because the combination of 1, 1, 4, 1 rotation, and 1 rotates forward, stops, and reverses.
), 1-Also, there is an advantage that the speed of intermittent paper feeding can be increased because the operation of 1) and 1) is performed fj) by the rotation part uJK of the input shaft in one direction.

M/C1・jl;・M-riJ The strip was cut by the knife because the feed roller reversed in case of carelessness11. At point 'j, a force of .11 is applied to this, and even if it is in an incomplete 9J cut state, it becomes possible to complete the cut by reverse rotation. In other words, cutting errors can also be prevented or reduced.

Hereinafter, details of Example #II (non-explosion) will be explained based on FIG. 1h.

This embodiment was implemented as a paper feeding device for a packaging machine, and the wrapping paper (a), which is wound into a roll and bound by H, is cut by a set of rotary counters. 1. This die-cut wrapping paper alone (P) or the article to be packaged (B) is attached to the V-wrapping means.

For this reason, the above-mentioned feeding device for the wrapping paper fa) is employed to prevent the wrapping paper from falling onto the fixed blade (11) of the cutter.

This feeding device consists of a feeding means 3 for feeding the object to be packaged to a predetermined position (17 positions) and a pair of claws 1 opposite to this for holding the object to be packaged in a half-packed state. (4), (
This is done in conjunction with the opening/closing ωj operation of 4). In a packaging machine using this feeding device, this outlet section (
