Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for arranging articles in several rows, each with a plurality of rows, on a product stand, especially flexible articles that are likely to be deformed when picked up by hand, such as the skin of pickled vegetables, in one row. The present invention relates to an article scooping and transferring device which repeats the operation of repeatedly scooping out articles one by one and transferring them onto a conveyor by increasing the interval between the articles in the row so as to be convenient for packaging, etc. The purpose is to
To automate the work of automatically widening the pitch of a row of articles arranged on an article stand and transferring them to a conveyor.

A preferred embodiment of the present invention will be described.

In the figure, 1 is a machine frame assembled into a rectangular frame shape, and a feeding device 3 such as a feeding table or conveyor that feeds a product stand 2 into the machine frame and stops it at a fixed position as shown in Fig. 1, and a supply device 3 on the product stand 2. A conveyor 4 for conveying articles a arranged in several rows in a zigzag shape as shown in the figure in the direction of arrow X is installed oppositely at a constant interval. On the product table 2, there is a flexible article (or a hard similar article) made of gyoza skin made by layering several plaques made by kneading flour such as wheat flour, which is the main raw material, and rolling it with a roller, and then cutting it out with a cutting die. a
, and the articles A in each column L, ~Ls
The pitch P of -M and the pitch p of the sections A1 to M, which receive each article on the conveyor 4, are made different depending on the next process such as packaging, and have a relationship of p<p. Distance S+”S between each row of articles, ~Ls and the conveyor 4
5 is also different. (See FIG. 10) A guide rail 5.5 and a rack 6.6, which are perpendicular to the conveyance direction of the conveyor 4, are fixed on the machine frame 1. Further, a reciprocating transfer frame 7 is installed which is connected to the guide rail 5.5 by a connecting rod 9 and in which a slider 8.8 is slidably fitted.

The transfer frame 7 reversibly rotates an interlocking shaft 12 via a belt 10a, a drive shaft 11, etc. by a reversible motor 10 mounted thereon, and engages the rack 6 with binions 13 and 13 at both ends of the shaft via an intermediate gear. Together, they cause reciprocating movement.

The reversible motor 10 is operated by a sequencer installed in a control box (not shown) to sequentially index the distances -Ls and return to T- after L5.
This is done by determining the number of rotations. Note that this sequencer also acts on changing the stroke of the first cylinder, which will be described later.

As shown clearly in FIGS. 2.5 to 6, a device plate 14 having a roughly T-shaped cross section with both ends fixed to the lower surface of the slider 8.8 is attached to the transfer frame 7, and a guide rail 15 is installed below the front surface of the device plate 14. The short first cylinder 17 on the right side of FIGS. 2-3 and the long second cylinder 19 on the left side of FIGS. 2
0 to the right and left.

FIG. 7 shows an exploded view of the scooping device 36, in which a product table 2 is attached to the bottom surface of a sliding piece 21 provided with a sliding groove 22 that can be slid freely left and right on the back side of the guide rail 15 described above. A supporting piece 24 of the scooping plate 23 protruding in the direction of is pivoted on a horizontal shaft 25 so as to be able to swing up and down, and a pressure receiving roll 26 is provided that protrudes rearward from the supporting piece 24. A T-shaped extrusion piece 27 provided with a pressing surface 28 that follows a part of the outer shape of the product a is brought into contact with the product a, and its legs 29 are passed through the support piece 24 and protruded rearward. Further, the sliding piece 21 is provided with a clamping plate 30 corresponding to the scooping plate 23 and an engaging protrusion 31 on the front surface.

As shown in FIGS. 2 to 4, the above-mentioned sliding piece 21 is
The number of sliding grooves 22 is fitted into the guide rail 15, and the connecting arms 32 are protruded from the sliding pieces 21a and 21m at both ends to match the numbers of the rows A-M of the first cylinder 17.
and the rod 20 of the second cylinder 19, and each sliding piece 21 has connecting slots 34 and 35 formed on the left and right sides of the connecting piece 33. is slidably fitted into the engaging protrusion 31 and secured with a retaining screw to prevent it from coming off. Sliding pieces 21a and 21m at both ends
The connecting pieces 33 are fitted one by one. When the connecting pieces 33 contract each rod 18.20 of the first and second cylinders I7.19, each scooping plate 23 matches the pitch P of A to M in the row of products a, as shown by the solid line in FIG. 1 and in FIG. When the rod 18.2o is extended, each scooping plate 23 matches the pitch p of each section A, ~M+ of the conveyor 4, causing the chain line in FIG. 1 and the spreading shown in FIG. 3.4. The long connecting holes 34 and 35 have a length that allows the scooping plates 23 to gather and spread out at equal intervals.

On the back side of the device plate 14, as shown in FIG. 4, there is a swing control plate 38 suspended by a plurality of parallel links 37, and a third cylinder 39 for swing control in which a rod 40 is connected to one link 37. Install. The swing control plate 38 is the scooping plate 2 described above.
This contact is made with the pressure receiving roller 26 of No. 3. (5th.
(See FIG. 6) A support frame 42 is attached to the upper side of the machine frame 1 in FIG. 1 (left side in FIG. 8) to which a magnet 41 corresponding to the rear end of the leg 29 of the extrusion piece 27 is attached.

The scooping device 36 picks up each row L of articles a arranged on the product table 2.
1 to Ls are scooped out sequentially by the scooping plate 23, and the difference in movement stroke due to the difference in the distance 81 to Ss from the conveyor 5 is determined by adjusting the rotation speed of the reversible motor 10 by a sequencer (not shown) as noted above. This is done by sequentially changing the five times as a - cycle. Furthermore, in this embodiment, the product a has a zigzag shape for each row L1 to Ls, and correspondingly, the pressurized fluid feed rate of the first shilling, which is acted upon by compressed fluid more powerful than the second shilling 19, is change. This change is controlled by the sequencer as described above.

To explain the operation of this embodiment, the last row 5 on the product table 2
The scooping device '36 scoops out the article a with the scooping plate 23 at the inclination angle shown in FIG. 5, and simultaneously sets the scooping plate 23 at the horizontal angle shown in FIG. Due to the reversal and the extension of the rod 20 of the second shilling 19, the rod 20 of the second shilling 19 is retracted in a spread-out manner to the position indicated by the chain line in FIG. The rear end hits the magnet 41 and moves relatively forward on the scooping plate 23, thereby moving the articles A-M to sections A1 to M1 of the conveyor 4, but the product stand 2 automatically moves forward. Or, when it is replaced manually, the reversible motor M is moved to the first row, and the transfer frame 7 and the scooping device 36 move forward at a rotation speed that brings the scooping plate 23 into contact with the product a, and the legs that are attracted by the magnet 41 are moved forward. 29 moves the extrusion plate 27 relatively backward on the scooping plate 23, thereby slightly delaying its forward movement. On the other hand, the first cylinder 17 does not expand or contract, and the scooping device 36 at the left end in FIG.
is fixed at a position (2) that matches A of the article a in the first row L1 of the product table 2, and the second sill 19 contracts the rod 20 to open the connecting elongated holes 34 and 35 of the plurality of connecting pieces 33. Depending on the length of , they gather as shown in Figure 2. By controlling the rotational speed of the reversible motor 10, when the movement of the scooping device to the first row LL by the transfer frame 7 is completed, the tip of the scooping plate 23 has reached about half of the article a, as shown in FIG. Even if the pressing surface 28 of the scooping and pressing piece 27 moves forward, the contact surface 28 is pushed back by the article a and retreats. (
The pressing piece 27 becomes the rear part of the scooping plate 23 due to the action of the magnet 410, but since the plate 23 has a gentle slope with its tip lowered, some pieces move forward. ) Upon completion of the above-mentioned scooping operation, the third cylinder 390 rod 40 contracts and the parallel link 37 is brought to an angle of 02. Therefore, the swing control plate 38 is lowered, and each pressure receiving roller 26
Hold the scooping plate 23 in a horizontal position as shown in Fig. 6,
The article a on the scooping plate 23 is lightly sandwiched between it and the pinching plate 30.

Following this, the reversible motor 10 rotates in reverse and begins to move backward, and at the same time the second sill 19 extends the rod 20. Therefore, each sliding piece 21 is different from the sliding piece 21 at the right end in FIG.
With point a as a reference, the article a, which is unfolded as shown in FIGS. 3 and 4 by the action of the connecting slots 34 and 35 of each connecting piece 33 and held by the scooping plate 23, is aligned with the sections A1 to M1 of the conveyor 4. In order to move the swing control plate 38, which has caused the third cylinder 39 to extend the parallel link 37 at an angle θ1, upward as shown in FIG.
The pressure of the scooping plate 23 is loosened, and the scooping plate 23 swings toward the section AI-M+, thereby separating the article a from the lower surface of the scooping plate 30. At that time, the rear end of the leg 29 of the extrusion piece 27 comes into contact with the magnet 41 and moves relatively forward on the pressing surface 28, and the front end of the extrusion piece 27 on the right side in FIG. Since it swings in conjunction with the supporting piece 24,
The articles a on the scooping plate 23 are in sections A1 to M where the pitch is p.

is pushed out. Immediately after the extrusion, the one-way conveyor 4 transports the article a intermittently.

The products in the second row of product table 2 are placed in the first row by a zigzag arrangement.
Since it is slightly offset to the left in the figure, the rod 18 of the first shilling 17 aligns the left end sliding piece 212 and scooping plate 23 with the position of the article A in the second row L2 (Fig. 9), and then 2 shilling 19 to advance the sliding piece 21 etc. in the same manner as described above, and the reversible motor M rotates at a slightly higher number of revolutions than the previous time, and repeats the operation detailed above. Figure 9 shows sliding piece 2 at position ■.
A set based on 1a is shown.

The present invention has the structure and function as clarified by the above-mentioned examples, and is arranged in several rows, each row having a constant pitch P, and transporting the plurality of articles with a pitch P larger than the pitch P. The scooping device automatically gathers and unfurls so as to automatically cause the transfer operation to the section of the conveyor, and furthermore, it automatically collects and spreads the scooping device to automatically cause the transfer operation to the section of the conveyor. This system automatically changes the speed of the reversible motor that reciprocates the scooping device to accommodate the difference, and has the excellent effect of automating this series of operations.
