Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial application field" The present invention relates to a synthetic resin film bag feeding device for a bagging machine for poultry manure or the like.

"Prior Art" Conventionally, since a relatively flexible synthetic resin film bag has a weak waist, the waist bends when the bag is fed to an automatic bagging machine for poultry manure etc. Since it is not determined, it was difficult to hold the opening with a holding machine.

"Problems to be solved by the invention" This proposal holds a relatively weak synthetic resin film bag (heavy bag) in an upright state with one opening addressed to the top, and the position of the opening is fixed. It is an object to obtain a device that can be held in position and automatically fed to an automatic bagging machine.

[Means for Solving Problems] In order to achieve the above-mentioned object, the present proposal is that a bag support plate is erected on the machine base so as to stand upright on the front side and tiltably tilted to the back side, and the bag bottom is formed on the lower part of the support plate. The receiving plate is provided so as to project from the front surface of the supporting plate, the bag feeding pinch roller is provided above the inclined state of the supporting plate, and the bag front pressing device is provided on the front surface of the supporting plate so as to be openable and closable, and the closed state is provided. It is configured by a synthetic resin film bag supply device including a bag lowering gap between the presser and the front surface of the support plate, and a drive device which is provided with a drive device which opens the presser when the support plate stands up and closes when the support plate tilts. is there.

"Operation" Therefore, when one sheet of synthetic resin film bag 9 (heavy bag) having one end opening is supplied from the bottom portion 9'to one of the bag feeding pinch rollers 5 and 6, the bag 9 is bottomed by the pinch rollers 5 and 6. From the bottom to enter the space t between the bag support plate 2 that is in an inclined state and the bag front pressing member 7 that is closed, and the bottom portion 9'contacts the bag bottom receiving plate 4 and is stopped (the bag 9 in that state). (Shown by phantom lines in FIGS. 1 and 2). After that, the support plate 2 is vertically erected by the drive device 8 and the upper end opening 9 ″ of the bag 9 is held in an upward state by the support plate 2 and the holding tool 7 so that the opening 9 ″ is opened. Can be clamped by the clamper 10. In this state, the drive device 8 operates to open the presser foot 7 (the state is shown by phantom lines in FIGS. 2, 3, and 4). Further, the supporting plate 2 is tilted to the position shown by the solid line in FIG. 2 by the driving device 8, and the holding member 7 is also closed by the driving device 8 via the gap t, and the pinch rollers 5 and 6 are operated in the same manner as described above. The operation of supplying the bag 9 is repeated.

[Example] A lower end of a bag support plate 2 is rotatably pivoted 3 to a machine base 1 by a horizontal pin, and a cylinder 11 is connected to the middle rear surface of the support plate 2 so that the support plate 2 is supported by the cylinder 11. Is tilted at a constant angle (shown by the solid line in FIG. 2) to an upright state (shown by the phantom line in FIG. 2) by pivoting forward and backward about the pivotal portion 3 to support it so that it can be tilted. A bag bottom receiving plate 4 is provided on the lower part of the support plate 2 so as to project toward the front, and bag supply pinch rollers 5 and 6 are provided on the upward extension line portion of the support plate 2 in the inclined state (constant angle). . The pinch rollers 5 and 6 are lower rollers 5.
A rubber guide roller 6 is in contact with the upper side of the lower roller 5, and a bag guide plate 12 is provided from the side of the lower roller 5 toward the upper end of the support plate 2.
In addition, a baggage guide plate 13 is provided from the outlets of the rollers 5 and 6 to the upper end of the support plate 2. On the front side of the support plate 2 thus constructed, the double-sided double-sided bag front retainers 7, 7 are pin 1
A bag lowering gap t is provided between the pressing members 7, 7 in the closed state and the front surface of the support plate 2 so as to be freely closed around the center of the support plates 2. The pressing members 7, 7 are shelf-like pressing members that support a plurality of vertical rods 7 "between upper and lower lateral arms 7 ', 7', and the lower end of the vertical rods 7" is a groove formed in the receiving plate 4. 4 '
It is to prevent the bottom 9 ′ of the bag from falling from the receiving plate 4 by entering the inside. To open and close the pressers 7, 7, the bending bases of the lateral arms 7 ', 7'are connected by a cylinder 15 as shown in FIG.
By extending and contracting the cylinder 15, the lateral arms 7 ', 7'are pin 1
It suffices to open and close about 4 and 14, and the gap t can be maintained by blocking the rotation of the lateral arms 7'and 7'with stoppers 16 and 16. And the support plate 2
A drive device 8 that opens the holding tools 7 and 7 when standing up and closes them when tilting is formed to control the solenoid valves for operation of both cylinders 11 and 15 by a timing control device. , 15 are air cylinders, the driving device 8 may be a mechanical interlocking mechanism of the tilting of the support plate 2 and the opening / closing of the pressing members 7, 7. Reference numeral 17 in the drawing is a sucker for supplying the synthetic resin film bag 9, 18, 19 are cylinders for operating the sucker 17, and 20 is an automatic chicken dropping bagging machine.

"Effect" Since the present invention is configured as described above, one synthetic resin film bag 9 having a weak rigidity is supplied to the supporting plate 2 in an inclined state, and the bag 9 is supplied.
There is a merit that the support plate 2 can be made to stand upright without bending and the upper end opening 9 ″ of the bag 9 standing upright can be safely supplied to the sandwiching machine 10 of the automatic bagger 20.
