  An embodiment of the pouch supply apparatus of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view showing the configuration of the pouch supply apparatus of the present invention.

  In the pouch supply apparatus 100 of FIG. 1, reference numeral 20 denotes a pouch transport belt conveyor, which places the pouch stack 10 from the start end 20a to the end 20b and advances it to the right. 20c is a pulley, 20d is a drive shaft, and 20e is a drive motor.

  Above the start end 20a of the pouch conveyor belt conveyor 20, there is an inlet 20x for the pouch stack 10, and at the end 20b there is an outlet 20y for discharging the pouches one by one.

  The stacked body 10 shows a state in which a plurality of pouches 1, for example, several tens of sheets are stacked. However, the pouches 1 of the stack 10 are stacked with the bag-shaped bottom 1b as the tip in the traveling direction of the belt conveyor 20.

  By accumulating as described above, the tip of the pouch 1 at the discharge port 20y always becomes the bag-shaped bottom 1b, and the bottom surface can be stably adsorbed and held (chucked) regardless of the shape of the bag-shaped mouth 1a of the pouch. , Improve reliability.

  Reference numeral 50 denotes an inclined guide surface portion, and the guide surface faces the belt conveyor 20 on the lower side. The inclined guide surface portion 50 approaches the lower belt conveyor 20 as it proceeds to the right, and reaches the guide surface outlet portion 50d.

  As soon as the stack 10 is loaded from the loading slot 20x and placed on the belt conveyor 20, it moves to the right. The pouch 1 on the upper side of the stacked body 10 has the bag-like bottom 1b at the tip thereof in contact with the lower surface of the inclined guide surface portion 50 and is prevented from moving to the right side, and its tip is moved backward with respect to the lower pouch 1. To do. The lowermost pouch 1 travels on the belt conveyor 20, but gradually forms an inclined stack 11 as shown in FIGS.

  That is, in the inclined stack 11, the upper pouch 1 is stacked with respect to the lower pouch 1 so that the phase of travel at the tip thereof is delayed.

  In the above state, the lowermost pouch tip reaches the guide surface outlet 50d. In this guide surface exit portion 50d, if the opposing surface of the gap G between the guide surface exit portion 50d and the belt conveyor 20 continues to the end 20b of the belt conveyor, resistance to the movement is large, so the guide surface exit portion 50d to the end 20b In order to reduce movement resistance, a terminal horizontal guide surface portion 51 is provided so that the distance from the belt conveyor 20 is larger than the distance G.

  The surface on the belt conveyor side of the inclined guide surface portion 50 is provided with a plurality of grooves in the direction perpendicular to the traveling direction. This groove prevents the plurality of pouches from entering into a narrow space and becoming unable to move the integrated body 10 when the leading end of the pouch 1 contacts in the advancing direction. (See Figure 6)

  In the inclined guide surface portion 50, the inclined surface 50a is a straight portion, and the inclined surface of the guide surface outlet portion 50d is a curved portion. Further, the groove may be a mesh groove portion 50b by adding a groove in the traveling direction at a portion close to the guide surface outlet portion 50d.

  In this way, it is possible to prevent the pouch 1 from being bent and advanced due to an imbalance of the compression pressure in the direction perpendicular to the traveling direction of the belt conveyor 20 at the guide surface outlet 50d, and to eliminate supply failure.

Next, the structure of the terminal horizontal guide surface 51 will be described. The terminal horizontal guide surface portion 51 is provided with three rectangular holes having a width W and a length L along the central portion. Two side guides 53 are screwed and fixed on the terminal horizontal guide surface portion 51 as shown in FIG. At this time, the two side guides 53 are arranged so as to have a distance D.

  Three weight rollers 52 each having a cylindrical rod smaller than the height D and the diameter L are inserted into three rectangular holes formed on the bottom.

  With the above configuration, the pouch passing under the weight roller 52 is prevented from slipping on the belt conveyor 20, and even when the number of pouches to be conveyed becomes a small number or the last one, the predetermined position is ensured. Can be conveyed.

  FIG. 2 is a plan view showing the structure of the pouch conveying belt conveyor and the pouch bag width adjusting mechanism. FIG. 3 is a side view of FIG.

  With reference to FIGS. 2 and 3, the parallel spacing guide surfaces 80 </ b> L and R provided on both sides of the advance of the pouch 1 so that the pouch 1 does not move in the direction perpendicular to the advance direction will be described.

  The parallel spacing guide surfaces 80L and 80R can be moved in parallel so as to contact and separate the guide surfaces and the left and right spacings can be adjusted. That is, when the width determining shaft 80a is rotated, the rotating shaft of the interlocking shaft 80b on the end side is also rotated through the interlocking chain 80c, and the parallel spacing guide surfaces 80L, R are arranged so that the start end side and the end side of the belt conveyor are simultaneously contacted and separated. Move in parallel.

  Reference numerals 80d and 80e denote pulleys of the interlocking chain 80c.

  5A and 5B show the pouch take-out mechanism, where FIG. 5A is a front view, and FIG. 5B is a view taken along the arrow A in FIG. Hereinafter, the pouch take-out mechanism will be described with reference to FIGS. 1 and 5.

  In FIG. 1, a plurality of pouches on the lower side of the inclined stack 11 pass through the inclined guide surface outlet 50d, reach the end 20b of the belt conveyor 20 below the end horizontal guide surface 51, and further the pouch 1 at the lowest level. If the bag-like bottom portion 1b protrudes by a predetermined length (tip portion 30a), the photoelectric switch 30 that has detected it transmits the detection signal.

  A central control unit 90 composed of a computer receives the detection signal via a photoelectric switch signal receiving terminal 90a.

  The received central control unit 90 drives the first cylinder 42 of air or hydraulic control based on a predetermined program procedure, and moves the vacuum pad 41 connected to the first cylinder 42 to the bag shape of the lowest pouch 1. It moves so as to come into contact with the front end surface of the bottom surface 1b. Therefore, vacuum is performed by a vacuum source (not shown) connected to the vacuum pad 41 to adsorb the bag-like bottom 1b of the pouch 1.

  At this time, in order to complete the contact between the bag-like bottom portion 1b of the pouch 1 and the vacuum pad 41, a shaft 46 inserted in a vertically movable manner is provided in the shaft guide 47, and the rod tip portion at the lower end of the shaft 46 is provided. 45 is automatically pressed from above the stack 11 by its own weight. With the above mechanism, the suction of the pouch 1 by the vacuum pad 41 is reliably performed, and the reliability is improved.

  Next, when the central control unit 90 recognizes the suction of the lowest pouch 1 by the vacuum pad 41, it sends a signal for contraction to the second cylinder 43. The second cylinder-equipped arm 43a rotates and the rotation shaft 44 rotates.

  When the rotating shaft 44 rotates, the first cylinder 42 connected in the vicinity of the center of the rotating shaft 44 rotates while adsorbed to the bag-like bottom portion 1b of the pouch 1, so that only the lowermost pouch 1 eventually has its tip. Is bent downward by about 45 degrees and pulled out.

  At the same time, the central control unit 90 turns off the suction signal to the vacuum pad 41 and returns the first cylinder 42 to its original state.

  A pouch receiving guide 60a is placed on the tip of the bent pouch 1, and the process proceeds to the next step. Along with the suction signal OFF, the central control unit 90 sends a signal to the third cylinder 48, lifts the shaft 46 upward, and pulls out the pouch 1 to the tip 30a of the pouch 1 that becomes the next lowest position. Smooth movement.

  If the photoelectric switch 30 detects a predetermined length protrusion of the tip of the pouch 1, the vacuum pad 41 of the first cylinder 42 is brought into contact with the bottom surface of the pouch 1, and the third cylinder is placed at a position where the shaft 46 can be pushed down from above by its own weight. Return to the original state. The above operation is repeated.

  4A and 4B show the structures of the chuck moving mechanism and the pouch upright mechanism. FIG. 4A is a plan view, and FIG. 4B is a structural sectional view of the arm interval adjusting mechanism 75.

  The chuck moving mechanism 60 will be described in detail with reference to FIGS.

Here, 61 is a chuck portion that grips the center of the bag-like bottom portion 1b of the pouch 1, 64 is a chuck support portion that supports the chuck portion 61, 62 is a guide rail that moves the chuck support portion 64, and 63 is a servo motor for driving. It is.

  The chuck moving mechanism 60 configured as described above recognizes the timing when the bag-like bottom 1b at the tip of the pouch 1 is placed on the pouch receiving guide 60a, and the chuck moves to the highest position where the chuck can grip the pouch 1. The support part 64 is moved upward. When reaching the uppermost position, the central control unit 90 subsequently sends a signal for closing the chuck to the chuck 61 to grip the center of the pouch-shaped bottom 1b of the pouch 1.

  The central control unit 90 then sends a signal to the chuck support unit 64 to move it downward. At this time, the pouch-shaped sides of the pouch 1 taken out move on the two arms 71 respectively. The moving length range may be the length of the bag-like pouch 1. That is, the length of the two arms 71 may be about the length of the pouch 1 in the bag shape.
