Works are each held at a plurality of positions spaced apart from one another and transferred by a roller conveyor (1). A table (102) facing the conveyor (1) from below supports the works conveyed by the conveyor (1), moves away from the position opposing the conveyor (1) when a work is conveyed to a predetermined position, and lets the work fall onto a receiving tray (105).

Description

Clear Stacker Technology Field

The present invention relates to a stacker for stacking the work, and more specifically, an improvement of a transport unit for transporting the work in the stacker. It is related to. Background technology

In sewing factories, etc., the fabric and the interlining are piled up in the order in which they were sent after being heat-pressed by the press and then sent to the force station. Get

As an example of this status, the patent application for patents of the United States of America and the Republic of Germany P 1 6 6 0 9 8 2 .8 and the application for application for utility model registration of Japan are published. There is one disclosed in No. 4 2 5 3 2 in 6 1 year. These stackers use a bell conveyor as a transporting means for transporting the smoke such as thermo-compressed fabric. Moreover, on the stacker base, a table is movably installed between the work position and the retract position. When the table is in working position ii, it is set up so that it is very close to the orbit of the belt conveyor and is in close proximity to the conveyor from below. It is. The work sent from the press machine is pressed against the table and held by the computer, and the work force test is performed along with the orbit of the conveyor. — Moved on the bull. Then, when the work is moved to the predetermined position, the table moves to the retracted position, and the work falls downward and is loaded and collected in the receiving part.

In the case where they are electrically charged, respectively, due to the bending, work and friction, the work force due to the electrostatic induction between them is high. 《Benolet is sucking I. And, even though the table was moved to the retracted position, the work was strongly attracted to its partial force belt, and in a normal posture. There are some things that do not fall. For this reason, it is possible to load the work in an unnatural state such as when the work is bent. Therefore, it is not possible to achieve the original purpose of the stacker, such as that the stackers are loaded in order.

In addition, after the work has been conveyed to some extent, and when the work is a blended fabric of chemical fibers, the electrostatic induction force and the force will be greater. It has the strength that it does not fall, and it does not fall when it is stretched over the wall. In spite of this, if the smoke is sequentially transported, these fabrics will be in a disordered state near the drop position, and it will be necessary to manually sort them.

In order to prevent the negative effects of static electricity, it is possible to install a static eliminator and use conductive fibers. However, when the table retreats, the electrostatic induction force has a maximum value during the moment when the work and the table are separated from each other. Because of that. For example, if a Teflon-based phenol is used as a work and transported at 100% to the Polestenol, the table will retreat. The static electricity between them shows a value of 10 to 20 kV (measured with a current collector, Kasuga Electric Co., Ltd. KS-525 5 type), and the static electricity It is more than 10 times.

There is no static eliminator that can remove large static electricity such as those mentioned above all over the work in an instant, and a stand with these protective measures. Even in the case of the work, the first-part force of the work (strong suction on the belt I) and the force (many) cause the disturbance of the posture.

Furthermore, if a static eliminator is installed, the size of the entire equipment will be increased. In addition, there is a problem that the price increases when the conductive fiber is used.

In addition, a method of discharging electrostatic charge by blowing on an ion with a corona discharger is also proposed, but this method does not work. It is known that static electricity does not have a static eliminating effect on a stacker that adheres to the belt in a state where there is no space.

The purpose of the present invention is to make it possible to make the entire equipment compact, and to use an inexpensive work, but also to make the work quieter. It provides a stacker that eliminates the negative effects of electricity and ensures tidy work load recovery. Announcement of ' This invention is to solve the problems described in i at once, and the gist of the invention is to carry a plurality of works that are sequentially sent from an external device. — A stacker that stacks and collects the work in the collection unit. ヽ Transport means that holds and transports each work at multiple locations that are separated from each other. From the opposite side, it supports the rake that is transported by the transporting means, and when the rake is transported to a predetermined position, it is retracted from the position force facing the transporting means. It is necessary to provide a fall permitting means for dropping the work into the recovery section. Brief description of the drawings

Below, an example of the present invention will be described with reference to Figs.

7 Explain in detail based on the figure.

In Fig. 4, the stacker 100 is located adjacent to a press machine that is not shown. Then, the work formed by crimping the interlining and the fabric with the press machine is carried out through the belt machine 1 08. It is sent to the car 100. The above-mentioned status force — 10 is a metal main body 10 1 which is almost a rectangular frame, and has a basic skeleton. Then, at the upper part of the starter force 1100, the roller compo- ner 1 force that conveys the work is adjusted with the bracket 17 and the adjustment suspension network. It is suspended and supported from the top frame 1 0 1 a of the main body 1 0 1 by means of the g 15.

As shown in Fig. 1, the roller computer 1 has a metal plate 5 in the form of a long plate, and a plurality of metal frames 5 arranged between the metal frames 5. It is formed so that it extends horizontally and more toward the roller 3.

The rear end (left part) of the frame 5 is axially supported so as to be vertically movable with respect to the bracket 17.

As shown in Fig. 2, each roller 3 is composed of three closed cylinders 3a formed by the urethane bowl, and these circles are formed. Cylindrical body 3 a Force 《Spindle 7 rotatably supports metal frame 5 ′. Then, as shown in Fig. 1, the bottom edge of the roller 3 Is always arranged so that it is lower than the lower edge of the side plate of the Freight A 5 ·. In this embodiment, 12 rollers 3 are arranged in the horizontal direction at equal intervals.

Again, referring to Fig. 2, there is a toothed pulley 4 fitted between the cylindrical bodies 3a of each roller 3, respectively. The toothed pulley 4 is fitted with a timing belt 2 extending in the length direction of the frame 5.

As shown in Figs. 1 and 3, the tension roller 6 is rotatably supported by the metal frame 5 between the rollers 3 and the tire 6 is provided with a type. By applying the appropriate tension to the mining belt 2, the good relationship between the toothed pulley 4 and the timing belt 2 can be maintained. I will. Further, the guide rollers 6a are rotatably arranged in the vicinity of the roller 3 at the front and rear ends of the roller computer 1, respectively, and the timing is set. The belt 2 is separated from the lower edge side force of the toothed pulley 4.

Further, as shown in Fig. 2, a driven toothed pulley 13 is attached to one end of the foremost support shaft 7, and a freewheel is attached as shown in Fig. 3. On the output shaft of the motor 1 11 mounted on the front end of the frame 5, a drive toothed transmission pulley 14 is provided. Then, both timings 1 3 and 1 4 are vigorously hung on the timing ven- tor 12. When the pulley 13 is rotated by the motor 1 1, the toothed pulley 4 is driven through the timing belt 2. It is moved and the roller 3 is rotated.

In addition, the adjustment knob 15 is explained by saying that when the frame 5 is on the rear side of the motor 1 1, the roller conveyor 1 is on the up and down. Pneumatic up / down cylinder that is activated is set up for 10 times. The same cylinder 10 is provided with two knobs 10a and 10b, and by properly operating them, the cylinder 1 The operating speed of 0 is controlled. At the upper end of the rod of cylinder 1 0, a bolt 1 5b force is provided via a connecting plate 1 9. The upper end of this bonnet 15 is connected to the adjustment knob 15a located on the upper surface of the top frame 1 0 1a, and it is adjusted by adjusting the opening of this knob 15a. The height of the cover 1 is adjusted.

On the other hand, the rear part of the side surface of the frame 5 is provided with a long hole 9 extending in the front-rear direction, which is used to adjust the tension bolt 8 screwed into the frame 5. Therefore, the spindle 7 is moved back and forth in the long hole 9 through an adjusting mechanism (not shown) to adjust the tension of the timing bentoret 2. It has become so .

In addition, on the side of frame 5 there are rows of vertically extending elongated holes 18 in a row. The support shaft 7 which is inserted into these long holes 18 is always urged downward by the tension of the timing belt 2. The fixed pin 18a shown in Fig. 2 prevents the displacement of the support shaft 7 in the axial direction.

As shown in Figure 6, this roller computer 1 A slide table 10 2 is installed in the lower part, and the operating position accompanying the expansion and contraction of the taper drive cylinder 10 4 (Fig. 4) (chain line in Fig. 6). It is possible to move between the retreat position (solid position) and the retracted position (solid line position) in the accommodation section 120 provided at the rear of the main body 1 0 1. The slide tape holder 1 0 2 cooperates with the roller 3 in the operating position to carry the work by sandwiching the work, and in the retracted position. Receive the work and drop it on the tray 1 0 5

As shown in Fig. 4, as shown in Fig. 4, the upper and lower parts are sandwiched by the top frame 10 1 a, and the upper and lower parts are the emitters and receivers 10 3 a and 10 3 b, respectively. It has been set up. When the start of introduction of the work on the sensor 10 3 <Computer 1> is detected, the extension of the cylinder 10 and the increase of the motor 11 1 are detected. The operation starts. In addition, when it is detected that the introduction of the work on the sensor 10 3 <Computer 1 is completed, the cylinder 10 4 expands and the table is expanded. 1 0 2 is moved to the working position to the retracted position. At the same time, the motor 11 is stopped, the cylinder 10 is returned to its original position, and the computer 1 is returned to its original position. Be raised.

The receiving tray 1 0 5 is mounted on the lower part of the main body 1 and the pneumatic carrying cylinder 1 0 7 is loaded on the upper end of the rod 1 0 7 a. The pan 10 5 is moved up and down by the expansion and contraction of 7.

This saucepan 10 5 and the slide tape holder 10 2 Between the transmitters and receivers 10 6a and 1 0 6b, the load capacity sensor 1 0 6 force is installed and the load is loaded on the receiving tray 1 0 5. Detect the height of the ground. Then, based on the detection result of the load sensor 1 0 6, the cylinder 10 7 based on the detection result is always the work height slide table 1 0 2 It is controlled so that it is close to and constant.

In addition, a control box 1110 is installed below the conveyor 1080 that conveys inside the press machine and stacker 100. . Then, an operation panel is installed on the surface of the control box 110, and the control panel shown in Fig. 5 is installed on the inside. The electromagnetic control valves 1 1 3, 1 1 4 and 1 1 5 are opened and closed based on the output signals of various sensors.

Immediately, when the work sensor 103 detects that the work has been installed on the computer 1, the work starter signal is detected by the controller. Output to 1 1 1. When the sensor 10 3 detects that the work has been installed on the computer 1, it detects an installation end signal. Output to controller 1 1 1.

The ft capacity sensor 106 is the controller when it is detected that the height of the work loaded on the receiving tray 105 does not reach the specified value. Outputs the rising amount insufficient signal to the alarm 1 1 1. In addition, the loading sensor 10 6 is located on the receiving tray 10 5 depending on the height of the loaded work. When it reaches the fixed value, it outputs a rising completion signal to the contact port 1 1 1.

The controller 1 1 1 1 drives the motor 1 1 1 1 1 2 via the driver 1 1 2 when the input start signal is input. At the same time, the electromagnetic control valve 1 1 3 was controlled to supply air to one part of the climbing cylinder 10 and remove the air from the other part. And push cylinder 10 out.

When the controller 1 11 receives an end-of-installation signal, it switches the solenoid control valve 1 13 3 to control the rising and lowering cylinder 1 0. The cylinder 10 is pulled out, and the air is supplied to the other part to contract the cylinder 1 0. At the same time, the controller 1 1 1 controls the solenoid control valve 1 1 4 to supply air to one part of the table drive cylinder 1 0 4. At the same time, the air is pulled out from the other part and the cylinder 10 4 is ejected. Immediately after the end of this operation, the controller 1 1 1 switches the control valve 1 1 4 to its original state and contracts the cylinder 1 0 4. R.

The controller 1 1 1 controls the solenoid control valve 1 1 5 on the basis of a signal of insufficient increase in the load capacity sensor 1 0 6 car to carry the cylinder 1 1 0 7. Supply cylinders to one of the other parts of the factory, pull out the air from the other part of the factory, and project cylinder 1107. The controller 1 1 1 1 holds the electromagnetic control valve 1 1 5 in its current state based on the rising completion signal from the load sensor 1 06. Bearer Holds the holding cylinder 1 0 7 inextensible.

Next, I will explain how to use this stacker 100.

First, the conveyor belt 10 8 is transported to the work force << stacker 100 0 side. Then, the work is introduced into the main body 10 1. When this is detected by the sensor 10 3 force, the cylinder 10 is stretched, the roller computer 1 is pressed downward, and the bracket 17 It is rotated downward about the fulcrum. At the same time, the motor 11 is driven, the roller 3 force <turns on, and the work these rollers 3 and slide table 1 0. It is sandwiched between 2 and and transported in the fixed position. Then, when the completion of the work transfer is detected by the sensor 103, the cylinder 1040 is driven and the table 102 retreats. The work is moved to the retracted position, and the work is dropped and placed on the receiving tray 1 05.

On the other hand, at the same time when the table 102 is retracted, the motor 11 is stopped and the roller computer 1 is contracted due to the contraction of the cylinder 10. It is lifted and ready for the next transport. Then, the table 10 2 also returns to the original position at a low speed after the fall of the work. In addition, as the number of works loaded on the receiving tray 1 0 5 increases, the cylinder 1 0 7 shrinks, and the receiving tray 1 0 5 moves downward. It is possible.

With the above configuration, the work is carried into the stacker by the roller conveyor 1. Because of this In the case of the belt conveyor of the product, the entire surface of the work is in contact with the belt, whereas in the present embodiment, the work is carried out by each roller 3 Touch only the upper edge of the. Therefore, in this embodiment, the contact area between the computer 1 and the work is extremely small compared to the conventional product. For this reason, the static electricity that acts between the two does not prevent the work force from being stronger than the work force by one force.

Further, the roller 3 of the roller computer 1 is composed of three cylindrical cylinders 3a force, and each roller 3 also comes into contact with the work. It is constructed so that the area is small. Therefore, the above effects are even greater.

In addition, two parallel rows of timing belts 2 are turned at each mouth — by turning the bow I so as to pass between the cylindrical bodies 3 a of La 3. The force of the timing controller 2 is evenly distributed in the width direction of the computer 1. Therefore, the accessory metal part of the cylindrical body 3a of the roller 3 and the toothed pulley 4 come into contact with each other, and noise is generated, and wear of the metal part is avoided.

In addition, the action of the tension controller 8 and the long holes 9 and 18 makes it possible to adjust the force, force, and tension of the timing controller 2. Became . Therefore, it is suitable for the work and the kind of fabric because it is adjusted to the strength and force of the timing belt 2 and the roller 3. You can adjust the force of the work and the force of the work. And

In addition, depending on the carrying capacity of the work and the loading of the receiving trays 105, the various controllers 1 11 1 responded to the sensor detection. It has a structure that drives the undercarriage, and since the number of manual operations is extremely small, it can be operated efficiently and efficiently.

The present invention can also be implemented in the following modes. For example,

(1) As shown in Fig. 7, it is possible to arrange the cylindrical bodies 3a in a mutually intersecting manner. According to this structure, the contact area between the squid and the cylindrical body 3a becomes smaller, and it is more effective in the case of a mixed fabric of chemical fibers in which static electricity is significantly generated. is there .

(2) The roller 3 is replaced by three cylindrical cylinders 3a, and a large number of disk-shaped ones are arranged. In this way, the contact area between the work and the roller is smaller, and the electrostatic induction prevention effect is even greater.

(3) Roller 3 Insert a roll eye on the front surface to prevent a slip on the rock.

(4) Use a hydraulic cylinder instead of the air cylinder.

(5) As a device that supplies the work to the main body 101, an industrial machine is used in addition to the breath machine.
