Description

Detailed Description of the Invention [Objective of the Invention] (Industrial Field of Application) The present invention provides a method for feeding a continuous form or a plurality of stacked forms in a form processing line such as a collation line or a packaging line. This invention relates to a pin feeding device suitable for feeding.

(Prior Art) Conventionally, in a foam processing line, pins 2 are provided at regular intervals in the circumferential direction of an oblong belt 1, as shown in FIG. Marginal punches 4 provided at regular intervals in the longitudinal direction
The foam 3 is fed by engaging the pin 2.

(Problem to be Solved by the Invention) However, in the prior art, the marginal punch 4 of the form 3 is connected to the pin 2 that passes through the entrance corner of the belt 1.
As the pin 2 crosses diagonally from below to above with respect to the transport direction of the form 3, the tip of the pin 2 interferes with the form 3 and damages the marginal punch 4 of the form 3. There is.

Also, when the marginal punch 4 of the form 3 is pulled out from the pin 2 passing through the exit corner of the belt 1, the pin 2 crosses diagonally from above to below with respect to the transport direction of the form 3, and as a result, the pin 2 may interfere with the form 3 and damage the marginal punch 4 of the form 3.

An object of the present invention is to prevent a marginal punch provided in a form from interfering with a pin and being damaged during feeding by a pin feeding device.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides pins at regular intervals in the circumferential direction of an oblong belt, enables the belt to be driven, and provides constant intervals in the longitudinal direction of a continuous form. In a pin feeding device that feeds the form by engaging marginal punches provided at intervals with the pins, the ascending portion of the oblong belt is used as a pin feeding zone where the marginal punches engage the pins, and the belt The entry and exit form guides are installed above the entry and exit corners that connect to both ends of the ascending section, and the entry form guides are used to guide the pins from outside the movement trajectory of the pin passing through the entry corner. The form is guided to the engagement position with the pin in the feeding zone, and the exit form guide guides the form out of the movement trajectory of the pin passing through the exit corner portion from the engagement position with the pin in the pin feeding zone. It is configured as follows.

(effect) According to the present invention, the following effects (1) and (2) are achieved.

(1) On the entry side of the oblong belt, the continuous form is
Due to the presence of the entry form guide, the pin passes through the entry corner while being guided above the entry corner without interfering with the tip of the pin outside of its movement locus, and then In the pin feeding zone, the continuous form is inserted into a pin that moves substantially parallel to the continuous form, and fed.

(2) On the exit side of the oblong belt, the continuous form is
Due to the existence of the exit side form guide, ■After the pin is pulled out in advance from the pin that moves approximately parallel to the continuous form in the pin feed zone, ■The tip of the pin is pulled out of the movement trajectory of the pin passing through the exit side corner. It is guided and passes above the outlet corner portion without interfering with the exit corner portion.

Therefore, according to (1) and (2) above, it is possible to prevent the marginal punch provided on the form from interfering with the pin and being damaged during feeding by the pin feeding device.

(Example) FIG. 1 is a side view showing a first embodiment of the present invention, FIG. 2 is a perspective view of FIG. 1, and FIG. 3 is a schematic diagram showing a second embodiment of the present invention.

(First Embodiment) As shown in FIGS. 1 and 2, the pin feeding device 10 has a constant rotation speed in the circumferential direction of an endlessly looped oblong belt 13 wound around a driving pulley 11 and a driven pulley 12. Pins 14 are provided at intervals, and the belt 13 can be driven by a drive motor 15 connected to the drive pulley 11. Thereby, the pin feeding device 10 feeds the continuous form 3 by engaging the marginal punches 4 provided at regular intervals in the longitudinal direction of the continuous form 3 with the pins 14 .

At this time, the pin feeding device 10 includes a longitudinal horizontal pin feeding zone 18 extending from the upstream side to the downstream side in the feeding direction between the plate 16 and the lid 17, which is provided along the ascending portion of the belt 13. ing. The continuous form 3 is introduced into the pin feed zone 18 and its marginal punch 4 is inserted into the pin 1
4. The receiver plate 16 and the lid 17 are provided with notched pin passageways 16A and 17A, respectively.

However, in the pin feeding device 10, the inlet and outlet form guides 21 and 22 are installed above the inlet and outlet corner portions that are connected to both ends of the ascending portion of the belt 13. The form guides 21 and 22 are wedge-shaped, and the supports are attached to the plate 16.

The entrance form guide 21 has a guide surface 21A that slopes downward from the entrance side of the belt 13 toward the pin feeding zone 18.
and guides the form 3 from outside the locus of movement of the pin 14 passing through the entrance corner portion to a position where it engages with the pin 14 within the pin feeding zone 18.

The exit form guide 22 includes a guide surface 22A that slopes upward from the pin feeding zone 18 of the belt 13 toward the exit side, and passes through the exit side corner portion from the engagement position with the pin 14 in the pin feeding zone 18. The form 3 is guided out of the movement locus of the pin 14.

Next, the operation of the above embodiment will be explained.

(1) On the entry side of the elliptical belt 13, due to the presence of the entry side form guide 21, the continuous form 3 is connected to the tip of the pin 14 outside the locus of movement of the pin 14 passing through the entrance corner portion. It is guided and passes above the entrance corner part without interference, and then ■ pin feeding zone 1
At step 8, the continuous form 3 is inserted into the pin 14 which moves substantially parallel to the continuous form 3, and is fed.

(2) On the exit side of the oblong belt 13, due to the presence of the exit side form guide 22, the continuous form 3 is pulled out in advance from the pin 14 that moves approximately parallel to the continuous form 3 in the pin feeding zone 18. After that, (2) the pin 14 is guided above the exit corner portion and passes through the exit corner portion without interfering with the tip of the pin 14 outside the movement locus of the pin 14 passing through the exit corner portion.

Therefore, according to (1) and (2) above, the pin feeding device 1
It is possible to prevent the marginal punch 4 provided on the form 3 from interfering with the pin 14 and being damaged during feeding by zero.

(Second Embodiment) The pin feeding device 30 is substantially different from the pin feeding device M10 described above. The only reason is that it is constructed by bending.

In carrying out the present invention, the pin feeding device is not limited to one that feeds one continuous form, but can also be applied to one that feeds a plurality of stacked continuous forms.

[Effects of the Invention] As described above, according to the present invention, it is possible to prevent the marginal punch provided on the form from interfering with the pin and being damaged during feeding by the pin feeding device.
