It consists of a crank 96 equipped with.

(Function) The procedure for packaging an object using the packaging device configured as described above will be briefly described.

First, the article to be packaged A is placed on the delivery table 15, and a large number of wrapping papers B... are stacked on the stacking and feeding device 1.

Turn on the motor 90 and rotate the crank 91 in the direction of arrow S. As the crank 91 rotates, the support plates 93 and 93 move backward under the action of the connecting rod 92, and the rollers 93 and 93 move on the cam surfaces 951 and 952 of the plate cam 95.
3 rolls and the roller 963 force (transferring on the inclined cam surface 952 along the inclination starts), the crank 96 swings upward using its front end pivot point as a fulcrum, and receives this swinging force. The block 32 and the slide rods 31, 31 slide upward, and the lifting table 3 starts to rise.At the same time, the delivery roll 13 operates, and pinches the front end of the wrapping paper B that has been slightly delivered by the delivery member 12. Due to the rotational force, the wrapping paper B is quickly sent onto the rising table 3 [see FIG. Since the front and rear positions of the wrapping paper B can be adjusted in advance according to the size of the wrapping paper B, when the wrapping paper B is sent onto the table 3, the front side of the wrapping paper B is aligned between the vertical fixing plate 53 and the restraining plate 54. The rear sides are properly inserted and placed on the finger means 4 between them.

When the table 3 reaches the top dead center, the article A on the delivery table 15 is manually delivered onto the table 3 and stacked on the wrapping paper B [see Figure 3 (b)]. At the dead center, it is desirable to keep the table 3 stationary for a while. Therefore, when the support plate 93 reaches the end position of the backward movement (not shown in the figure), the limit switch is pressed to automatically stop the motor 9.
The rotation of 0 is stopped.

When the motor 90 is turned on again after confirming that the wrapping paper B and the packaged object A have been correctly placed on the table 3 as described above, the roller 96
3, the sliding table 3 rapidly descends along the inclined cam surface 952 of the plate cam 95. At the same time support plate 93.93
The forward movement of the supporting plates 93 and 93 is also started, and one sheet of wrapping paper B is fed out by this forward movement of the support plates 93 and 93. When the roller 963 starts rolling on the horizontal cam surface 951 and the table 3 reaches the bottom dead center, the table 3 remains still and the restraining plate 5
4 stands up and clamps the front end of the wrapping paper B with the fixing plate 53, and the finger means 4 passes over the table 3 [see FIG. 3(c)]. The time program for the downward and stationary movement of the table 3 and the reciprocating movement of the finger means 4 is appropriately set by setting the shape of the plate cam 95, the vertical stroke width of the table 3, the position of the reciprocating start point of the finger means 4, etc. . When the table 3 is lowered, the front side of the wrapping paper B is held between the restraining plate 54 and the fixing plate 53 and pulled up to stand up B2, and the rear side is held by the horizontal finger portion of the finger means 4. 41, and these upright pieces Bi and B2 are connected to the restraining plate 5.
The wrapping paper B is pulled back and forth under the clamping resistance between the wrapping paper B and the fixing plate 53, so that a so-called body press is performed, and the wrapping paper B is folded faithfully to the shape of the packaged item A without loosening.

When the finger means 4 hits the article A from above the wrapping paper B and starts to push it out, the horizontal finger plate 41 and the top plate 51 lift these upright pieces B1. B2 is folded back and forth, and its left and right sides are folded into the sides of the packaged item A by means of the upper and lower finger pieces 43, 44 and the fixing finger means 5.

Furthermore, the object to be packaged A is moved to the top plate 5 by the reciprocating finger means 4.

3 is a folded paper piece B4.3 which is half-opened by the downward movement of the folding plate 60.60. Fold it down into B4 under the neat fold line. At this time, the sealing tape applicator 2a applies a short piece of tape t to the overlapping part of the protruding paper pieces B and B2 of the front and back wrapping paper.
is glued. Then, as they are successively extruded, the half-open folded paper pieces B4. B4 is the intermediate folding member 75°75
The folding members 76 and 76 completely fold into both sides of the packaged object A, leaving neat folding lines on the lower sides of the folding members 76 and 76, and their tip portions protrude from the upper surface thereof.

These lower folded paper pieces B (B4) are removed from the side and top surfaces of the article A by swinging the protruding pieces 86, 86 of the next folding means 8 from the outwardly tilted position to the inwardly upright state. The package is tightly folded and adhered in the front-rear direction with the tape short piece t by the sealing tape applicator 2b, completing the entire packaging operation. The folding by this third folding means 8.8 is
This is done in synchronization with the downward movement of the folding plates 60, 60 in the previous process, and during the upward movement, the cam plate 83 compresses the swinging plate 84° 84 and the protruding pieces 86, 86 via the roller 82 to the compression spring 88. The folded paper strips B1 and B4 are tilted outward against the elastic force of the folded paper pieces B1 and B4 to receive the packaged article A with the folded paper pieces B1 and B4 facing upward and half open.

(Effects of the Invention) As described above, according to the packaging device of the present invention, the upper folded paper piece B3 formed by folding the sides of the wrapping paper B by the reciprocating finger means 4 and the fixed finger means 5;
B and the lower folded paper piece B4 are attached to the side of the packaged article A by the vertical movement of the folding plates 60 and 60 of the second folding means 6 and the action of the first folding means 7.
