Definitions

  • This invention relates to a stacker for stacking works, more particularly to an improvement of the conveying section for carrying the works into the main body of the stacker.
  • the work fed from the press is then carried over and pressed against the table by the conveyor as the conveyor belt turns.
  • the table moves back to the retracted position, and thus the work drops downward and is stacked or collected on a collecting section.
  • the level of static electricity at the moment the table is retracted jumps up to 10 to 20 KV which is at least 10 times the value before retraction (measured by a collecting type measuring instrument Model KS-525, manufactured by Kasuga Denki Kabushiki Kaisha).
  • the stacker of this invention receives a plurality of works fed successively from an external unit.
  • the works are collected and stacked onto a collecting section.
  • the stacker is characterized in that the stacker has a conveying means for carrying each work by holding it at several positions.
  • a work dropping means disposed under the conveying means and opposite thereto supports the work carried by the conveying means.
  • the work dropping means retracts from the position where it opposes the conveying means when the work is carried to a predetermined position to allow the work to drop onto a collecting section.
  • a stacker generally shown with the reference number 100 is disposed adjacent to a press not shown.
  • a work formed by subjecting a lining and a fabric to hot pressing is fed to the stacker 100 via a belt conveyor 108.
  • the stacker 100 has a substantially rectangular metallic main body 101 as a basic framework.
  • a roller conveyor 1 for carrying the work therein is suspended from the top rail 101a of the main body 101 via a bracket 17 and an adjuster 15.
  • the roller conveyor 1 consists of a long plate-like metal frame 5 and a plurality of rolls 3 arranged to extend horizontally parallel to one another in the metal frame 5. It should be noted that the rear end (left end in Fig. 1) portion of the frame 5 is supported on the bracket 17 to be movable vertically.
  • each roll 3 consists of three rollers 3a made of a urethane rubber. These rollers 3a are rotatably supported on the metal frame 5 by a shaft 7. The rolls 3 are arranged in such a way that the lower portions thereof extend below the lower edges of the side panels of the frame 5, as shown in Fig. 1.
  • a toothed pulley 4 is interposed between each pair of rollers 3a of each roll 3.
  • a timing belt 2 is extended along the longitudinal axis of the frame 5 over each row of toothed pulleys 4.
  • a tension roll 6 rotatably supported on the metal frame 5 is disposed between each pair of rolls 3 so as to apply appropriate tension to the timing belt 2 and maintain good engagement between the toothed pulleys and the timing belt 2.
  • Guide rolls 6a are rotatably disposed adjacent to the two outermost rolls 3 of the roller conveyor 1 so as to allow the timing belts 2 to be spaced from the lower portions of the toothed pulleys 4.
  • the foremost shaft 7 has a driven toothed pulley 13 at one end thereof as shown in Fig. 2.
  • a drive toothed pulley 14 is disposed on the output shaft of a motor 11 mounted on the front end portion of the frame 5 as shown in Fig. 1, and a timing belt 12 is extended over these two pulleys 13,14.
  • the driven pulley 13 is rotated by the motor 11, the toothed pulleys 4 are driven via the timing belts 2 to rotate the rolls 3.
  • a pneumatic cylinder 10 is disposed on the frame 5 behind the motor 11.
  • the pneumatic cylinder 10 allows the roller conveyor 1 to operate vertically.
  • the pneumatic cylinder 10 has two knobs 10a,10b, and the operational speed of the pneumatic cylinder 10 can be controlled by suitably manipulating these two knobs 10a,10b.
  • a bolt 15b is attached to the upper end of the rod of the pneumatic cylinder 10 via a connecting piece 19. The upper end of the bolt 15b is connected to a knob 15a disposed on the top rail 101a, and the height of the roller conveyor 1 can be adjusted by operating the knob 15a.
  • a horizontal slot 9 is formed at the rear end portions on the side panels of the frame 5 so that the rearmost shaft 7 can move horizontally within the slot 9 via an adjusting mechanism (not shown) by operating a tension bolt 8 screwed into the frame 5. In this manner, the tension to be applied to the timing belts 2 can be adjusted.
  • a row of vertical slots 18 are defined on the side panels of the frame 5.
  • the shafts 7 inserted through these slots 18 are constantly urged downward by the tension of the timing belt 2.
  • the stopper 18a shown in Fig. 2 is intended to prevent axial dislocation of the shaft 7.
  • a slide table 102 is disposed below the roller conveyor 1, which can move between the operating position (shown by the broken line in Fig. 6) and the retracted position (shown by the solid line) in the housing 120 disposed behind the main body 101 with the operation of the table driving cylinder 104 (see Fig. 4).
  • the slide table 102 carries a work in cooperation with the rolls 3, while it allows the work to drop onto a tray 105 when it moves back to the retracted position.
  • a light emitter 103a and a light receptor 103b, which together constitute a work sensor 103 are disposed on each side of the top rail 101a.
  • the pneumatic cylinder 10 and motor 11 are actuated.
  • the rod of the table driving cylinder 104 extends to return the slide table 102 from the operating position to the retracted position.
  • the motor 11 is stopped and the pneumatic cylinder 10 is retracted to resume the original posture so as to lift the roller conveyor 1 to the original position.
  • the tray 105 is mounted on the rod 107a of a pneumatic tray supporting cylinder 107 disposed in the bottom of the main body 1, which operates so as to move the tray 105 up and down.
  • a load sensor 106 consisting of a light emitter 106a and a light receptor 106b is disposed between the tray 105 and the slide table 102.
  • the load sensor 106 detects the height of the stacked works stacked on the tray 105.
  • the tray supporting cylinder 107 is designed to automatically adjust the distance between the top of the stacked works and the slide table 102 to maintain a constant separation based on the detection data of the load sensor 106.
  • a control box 110 is disposed below the belt conveyor 108 for transferring works from the press into the stacker 100.
  • the control box 110 has a control panel on the surface thereof, and a controller 111 disposed therein as shown in Fig. 5.
  • the controller 111 controls operation of the stacker by driving solenoid valves 113,114 and 115 based on the output signals of the respective sensors.
  • the work sensor 103 detects that a work is being carried to the roller conveyor 1, it outputs a start signal to the controller 111.
  • the work sensor 103 detects completion of the work carry-in operation at the conveyor 1, it outputs an end signal to the controller 111.
  • the load sensor 106 When the load sensor 106 detects that the height of the works stacked on the tray 105 has not reached yet a predetermined level, it outputs a signal to that effect (space-left signal) to the controller 111. When the load sensor 106 detects that the height of the works stacked on the tray 105 has reached the predetermined level, it outputs a signal to that effect (space-full signal) to the controller 111.
  • the controller 111 drives the motor 11 via a motor driver 112. At the same time, the controller 111 also operates the solenoid valve 113 so as to supply air to one chamber of the pneumatic cylinder 10 and evacuate air from the other chamber thereof, whereby the cylinder 10 is pushed out.
  • the controller 111 Upon receipt of the end signal, the controller 111 changes over the solenoid valve 113 so as to evacuate air from one chamber of the pneumatic cylinder 10 and supply air to the other chamber thereof, whereby the pneumatic cylinder 10 is retracted. At the same time, the controller 11 also operates the solenoid valve 114 so as to supply air to one chamber of the table driving cylinder 104 and evacuate air from the other chamber thereof, whereby the rod of the table driving cylinder 104 is pushed out. Immediately after completion of this operation, the controller 111 changes over the solenoid valve 114 to assume its original posture so as to retract the rod of the cylinder 104.
  • the controller 111 controls the solenoid valve 115 based on the space-not-full signal from the load sensor 106 so as to supply air to one chamber of the tray supporting cylinder 107 and evacuate air from the other chamber thereof, whereby the rod of the tray supporting cylinder 107 is pushed out.
  • the controller 111 Upon receipt of the space-full signal from the load sensor 106, the controller 111 maintains the solenoid valve 115 in the state and allows the tray supporting cylinder 107 to keep this position.
  • a work is first carried to the stacker 100 by the belt conveyor 108 and then carried into the main body 101 of the stacker 100.
  • the pneumatic cylinder 10 is extended to push down the roller conveyor 1, whereby the roller conveyor 1 is pivoted down on the bracket 17.
  • the motor 11 is driven to rotate the rolls 3, whereby the work is carried to the predetermined position by the cooperation of the rolls 3 and slide table 102.
  • the table driving cylinder 104 is actuated to move the slide table 102 to the retracted position, whereby the work drops to the tray 105 and stacked thereon.
  • the motor 11 is stopped in synchronization with the retraction of the slide table 102 to lift the roller conveyor 1 by the retraction of the cylinder 10 and assume a stand-by posture.
  • the slide table 102 quickly returns to the original position after dropping of the work.
  • the piston rod of the tray supporting cylinder 107 is retracted to move down the tray 105 little by little.
  • the work is carried into the stacker 100 by the roller conveyor 1 in the above embodiment, the work is designed to be brought into contact with the lower portion of each roll 3, in contrast with the conventional belt conveyor where the upper surface of the work is brought into contact with the entire surface of the belt. Accordingly, the contact area of the work with the roller conveyor 1 in this embodiment is very smaller than in the conventional conveyor, so that it never happens that the works are prevented from being released from the roller conveyor 1 by the static electricity exerted therebetween.
  • the contact area with the work in each roll 3 of the roller conveyor 1 is designed to be reduced by constituting each roll 3 with three rollers 3a, so that the effect described above can be exhibited more remarkably.
  • timing belts 2 Since two timing belts 2 are extended over the respective rows of toothed pulleys 4 interposed between the rollers 3a, the tension of the timing belts 2 can be applied evenly over the depth of the roller conveyor 1. Thus, the noise generated by the interference between the metal parts of the rollers 3a and the toothed pulleys 4 or abrasion of these parts and member can be prevented.
  • the tension applied to the timing belts 2 can be adjusted. Accordingly, since the tension applied by the timing belts 2 to the rolls 3 can in turn be adjusted, the force applied to the work can be adjusted so as to comply with the kind of cloth.
  • the respective cylinders are designed to be driven by the controller 111 in response to the conditions sensed by the respective sensors.
  • This control covers the entire process from the introduction of the works to the stacking thereof onto the tray 105. Thus minimal manual operation is required and the stacking operation can be facilitated.
  • This invention can also be embodied as follows:
