Abstract

PURPOSE:To prevent flaps from being caught by each other when the superposed blanks are sent out in succession from the lower part, by successively increasing the pushing-down angle towards the flap behind in the feeding-out direction for a plurality of flaps. CONSTITUTION:The endless belt 10 of each pushing-up mechanism 3a, 3b is press-attached on the flaps b2 and b3 in the second and third rows, viewed from the driving-out direction of blanks W piled on an elevator board 2. Each flap receiving plate 21 of each of flap supporting members 20a and 20b is set in a prescribed angle. Accordingly, the angle for the flap b3 in the third row behind by an angle for the flap b2 in the second row is increased. Then, the driving motor for each of pushing-up mechanisms 3a, 3b is driven, and the belt 10 is turned in a desired direction, i.e., the direction for pushing up the flap, and each of flaps b2, b3 is held in a state in the contact with each flap receiving plate 21.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a feeding device that sequentially feeds a large number of laminated paper box forming materials (hereinafter referred to as carton blanks) from above.

(Conventional technology) An example of the above carton blank is shown in FIG. 1O.

This carton blank (hereinafter simply referred to as blank) 1,
%I has flaps b1b on both sides of the blank body a, respectively.
2, b3 is provided by punching. When stacking a large number of blanks W and sending them to the next process, there are two types: in the direction of arrow X and in the direction of arrow Y. However, the arrow X direction refers to flaps bl, b2. b3 is the direction that does not interfere with each other. Further, the direction of arrow Y is the direction in which the rear flaps sequentially pass over the front flaps and are extended.

There is no problem in the direction of the arrow X, but when extending in the direction of the arrow Y, the upper and lower flaps may get caught with each other. The procedure is shown in Fig. 11.

Wl is the upper blank, W2 is the lower blank, and the respective flaps are b 1 a, b2 a, b3 from the front.
a.

Let b I b, b2 b, and b3 b. In this case, when the second stage flaps b2 a and b2 b are inclined downwardly from the oil section flaps bla and bib, the upper second stage flaps
The step flap b2a hooks at point C against the lower front flap bib. Further, the upper third stage flap b3a is hooked on the lower third stage flap b2b at point I).

For this reason, there is a drawback that the feeding is not carried out smoothly, and for this reason, a method is adopted in which the inclination of the flaps is manually corrected when stacking a large number of blanks.

(Problems to be Solved by the Invention) The above-mentioned blanks may be made of paper having a considerable thickness depending on the use, for example, detergent containers. Therefore, there are problems in that it requires a considerable amount of effort to manually suppress and correct a large number of laminated blank flaps.

In view of this point, the present invention aims to correct the posture of the flaps and smoothly perform the sequential delivery 5 of the stacked blanks starting from the two-most part.

(Means for Solving the Problems) A carton blank dispensing device (J) of the present invention that achieves the above object (Keruta ♂). Laminated 2
As you ascend the lifting platform one after another, grab the carton blank at the top of the platform! Looking down at the gripping transfer means for transferring 1 to the lateral force direction, the above gripping transition means is perpendicular to the carton blank transfer direction, and protrudes to the left 17. Front NS in the direction of transition by the means, l i) A flap push-up mechanism is provided in pairs for the flaps in the second and subsequent rows, and sequentially in the direction of transition - 7 - 17'' (as it progresses) Press: +

The belts 30a and 30b are provided with a large number of through holes 32 at a constant pitch, and the suction ducts 3]a and 31b each have suction grooves 33 formed on their lower surfaces to apply suction to the blank W through the through holes 32. It was designed to have an effect on the body.

Note that the positioning bar 5a of the navigation section is connected to its upper end.)
A fine gap is formed between the blanks 30a and 30b for sequentially feeding out the blanks W.

In the figure, reference numeral 25 indicates a bending position regulating rail provided as necessary.

In the above configuration, the blank W loaded on the lifting platform 2
Flaps b2 in the second and third rows when viewed from the direction of extension.
The endless belt IO of each push-up mechanism 3a to 3d is pressed against b3.

The flap receiving plates 21 of each of the flap support members 20a and 20b are set at a predetermined angle. That is, the angle with respect to the third blank b3 rearward than the angle with respect to the second row flap b2 is defined as a dog.

Thereafter, the drive motor 11 of each push-up mechanism 3 is driven, and the heald 10 is rotated in the direction of arrow A, that is, in the direction of pushing up the flaps, and each flap b2. b3 is each flap receiving plate 21

Figures 6 and 7 show a blank W whose flaps have been pressed and bent. In this case, the front flap b1 is in a horizontal state, α1 is the rotation angle of the second row flap b2, and α2 is the rotation angle pushed and bent by the third blank b3 and the second blank b2.

In this state, the belts 30a, 30 of the gripping and transferring means 4
By driving b, the loaded blanks W are sequentially fed out from the top. In this case, flaps bl, b2
, b3, the push-up angle is gradually increased toward the rear as described above, so that each flap can be smoothly extended without being caught by the flap of the blank located below.

Note that the feeding of the blank W by the gripping transfer means 4 is as follows:
- Before one blank W is completely fed out, the next blank W is sucked and fed out. That is, as shown in FIG. 9, the tip of the next blank W2 is superimposed below the rear end of the preceding blank W1 (in the shape of a loose peg) and sent out.

In this case, in order to supply the next process sequentially,
It may be preferable to turn the polymerization upside down and take it out from the bottom. The reversing procedure is shown in FIG. 8.6 The reversing mechanism 40 shown in FIG.
b is an endless belt, a drum 41 around which the endless belts 30a and 30b are wound, and the endless belt 3f,) a
, 30b and wound around the drum 4I.
2. Each belt has a guide roller 43.4
4 forms an outlet 45 which is 180° reversed from the feeding direction of the blank W in the feeding device I.

As a result, the leading edge of the next blank W2 is fed out so that it overlaps the rear upper part of the preceding blank W1. Therefore, it is possible to sequentially feed the materials onto the feed heald 46 for the next process.

(Effects of the Invention) According to the present invention, since the pressing down angle of the plurality of flaps is set to dog in sequence toward the rear flap in the feeding direction, when stacked blanks are sequentially fed out from the bottom, the flaps do not catch on each other. Therefore, feeding can be performed smoothly.
