One of the conditions for the automatic insertion device 100 for automatic insertion is that the inner diameter of the shrink film 220 is slightly larger than the outer diameter of the goods to be inserted. If the inner diameter of the shrink film 220 is smaller than the outer diameter of the goods to be inserted, it is not applicable physically, and if the inner diameter of the shrink film 220 is enough larger than the outer diameter of the goods to be inserted, it may applicable but the shrink film wrapping result state become deteriorate after heat shrinkage process.

(32) In the following description, the goods to be inserted have a substantially columnar shape.

(33) Hereinafter, each component of the automatic insertion device 100 for the mount equipped shrink film package is described.

(34) The mounting device 110 is a device in which the goods 300 to be inserted and the mount equipped shrink film package 200 are arranged in series along the inserting direction of the goods 300 to the mount equipped shrink film package 200. The configuration of the mounting device 110 may not be limited as long as the goods 300 and the mount equipped shrink film package 200 can be arranged in series. In the mounting device 110, a portion on which the goods 300 is placed and a portion on which the mount equipped shrink film packaging 200 is placed may be in an integral state or a separate state.

(35) For example, the goods 300 are provided one after another as sequentially conveyed by a conveyance system such as a belt conveyor, and the mount equipped shrink film package 200 is also provided from a stacker one after another sequentially conveyed by a conveyance system such as a belt conveyor. As shown in FIG. 1, when both the goods 300 and the mount equipped shrink film package 200 come to the predetermined position of the mounting device 110, both the goods 300 and the mount equipped shrink film package 200 are arrayed in series along to the inserting direction of the goods 300 to the mount equipped shrink film package 200.

(36) An interval between arrangement of the goods 300 and the mount equipped shrink film package 200 in the mounting device 110 is described. The interval between the goods 300 and the mount equipped shrink film package 200 in the mounting device 110 is set to be narrower than the length of the head part 121 of the insertion guide body 120 in the inserting direction. As described later, the insertion guide body 120 is inserted into the shrink film 220 and go through the inside of the shrink film tube to sure a state of the shrink film 220 is bulged up to the cylindrical shape with air pressure before operation of the goods inserting. After making this state the goods 300 is inserted to the shrink film 220 bulged up to the cylindrical shape with air pressure. Therefore, at the moment of contacting the front edge of the insertion guide body 120 to the goods 300, at least the rear end of the head part 121 of the insertion guide body 120 remains inside of the shrink film 220, not to go through the shrink film 220.

(37) This condition is described later with reference to FIG. 8

(38) Next, the insertion guide body 120 is described.

(39) The insertion guide body 120 includes a head part 121, an air blowing port 122, a goods suction part 123, an air pump connection part 124, and a negative pressure pump connection part 125.

(40) The head part 121 has a cylindrical outer shape. The outer diameter “r” of the head part 121 is substantially equal to or slightly smaller than an outer diameter “R” of the goods 300. That is, the head part 121 is previously inserted into the shrink film 220 of the mount equipped shrink film package 200 and the shrink film 220 is bulged up to a substantially cylindrical shape in advance so the goods 300 to be inserted can be easily inserted.

(41) The air blowing port 122 is an air blowing part for blowing air from the inside of the head part 121 toward the outer surface, and at least one air blowing port 122 is provided on the side surface of the head part 121. An air pressure is appropriately applied to the air blowing port 122 to blow out air from the inside. The air blowing port 122 may be a hole or a groove-shaped (air blowing groove). In this example, an air blowing port 122 is described as a hole.

(42) In this example, air is blown out through the air pump connection part 124 which is connected to the air pressure pump (not shown) for providing air pressure for air blowing to the air blowing port 122.

(43) Next, air pump connection part 124 is a connection port with an air pump (not shown) for blowing air by applying a predetermined air pressure. It blows air to the air blowing port 122. The internal structure of the head part 121, which is a supply passage of air from the air pressure pump connection part 124 to the air blowing port 122, is not shown. Any configuration which can provide airtight space reaching the air blowing port 122 from the air pressure pump connection part 124 can be employed.

(44) FIG. 2 is a schematic view showing a state in which air is supplied from an air blowing port 122 of the insertion guide body 120. As shown in FIG. 2 (b), when the head part 121 is inserted into the shrink film 220, the state of the shrink film 220 become cylindrical shape bulged by air pressure because air is blown out from the air blowing port 122 into the shrink film 220.

(45) The amount of air blown out from the air blowing port 122 and the air injection speed may be adjusted according to the size of the shrink film 220 and the size of the goods 300.

(46) Next, the goods suction part 123 is described.

(47) The goods suction part 123 is a suction mechanism for goods 300 contacted at the front of the head part 121 for suctioning. A negative pressure for air suction is provided to the goods suction part 123 via a negative pressure pump connection part 125. In another configuration, a suction disk can be employed as long as the goods 300 can be securely suctioned.

(48) In this Embodiment 1, the goods suction part 123 is suctioning means for sliding the goods 300 along the inserting direction in the sliding operation of the insertion guide body 120. The goods 300 are slid along the inserting direction by pulling the goods 300 together with the sliding movement of the insertion guide body 120 while suctioning the goods 300 by the object suction section 123.

(49) It is preferable that the outer diameter of the goods suction part 123 is smaller than that of the head part 121 of the insertion guide body and smaller than the inner diameter of the shrink film 220. As shown in FIG. 1, if the outer diameter of the goods suction part 123 is smaller than that of the head part 121 of the insertion guide body. The outer diameter of the insertion guide body 120 decreases toward the head. The goods suction part 123, which is installed at the head part 121, can be easily inserted into the inside of the shrink film 220, and thereafter, the head part 121 followed by the whole insertion guide body 120 can be smoothly inserted into the shrink film 220.

(50) Negative air pressure for air suction is provided to the goods suction part 123 via the negative pressure pump connection part 125.

(51) The negative pressure pump connection part 125 is a connection port with an air pump (not shown) for suctioning air by applying predetermined negative air pressure, and suctions air from the goods suction part 123. The internal structure of the head part 121, which is a suction passage of air from the negative pressure pump connection part 125 to the goods suction part 123, is not shown. Any configuration that can provide airtight space reaching the air blowing port 122 from the air pressure pump connection part 124 can be employed.

(52) The activation and the deactivation of the application of negative air pressure to the goods suction part 123 can be controlled by controlling the opening and closing of a connection with the negative pressure pump connection part 125, and as a result, air suction ON and OFF in the goods suction part 123 can be switched.

(53) Next, the slider device 130 is described.

(54) The slider device 130 is a device for sliding either or both the insertion guide body 120 and the mount equipped shrink film package 200. The slide motion is not limited as long as the insertion guide body 120 and the mount equipped shrink film package 200 are relatively moved. Either the insertion guide body 120 or the mount equipped shrink film package 200 may be moved. In this embodiment, the way in which the insertion guide body 120 slides is employed.

(55) The insertion guide body 120 is pushed out from a rear end (left side in the figure) by the slider device 130, and the insertion guide body 120 is inserted into the shrink film 220 of the mount equipped shrink film package 200 from its head. The insertion guide body 120 is further slid and moved until the insertion guide body 120 reaches the goods 300. The same result can be obtained if the mount equipped shrink film package 200 slides and the position of the insertion guide body 120 is fixed, and the insertion guide body 120 accepts the mount equipped shrink film package 200.

(56) This motion is executed in the inserting preparation operation described later.

(57) In Embodiment 1, at the end of the inserting preparation operation, the goods suction part 123 contacts with the goods 300 and starts suctioning.

(58) In this example, during the inserting operation, a slide motion of the insertion guide body 120 is executed by pulling the insertion guide body 120 back from the rear side. During the slide motion, negative air pressure is being applied to the goods suction part 123 via the negative pressure pump connection part 125. The goods suction part 123 slides and moves in the shrink film 220 while suctioning and pulling the goods 300. In this Embodiment 1, the slide motion of the insertion guide body 120 with the goods suction part 123 carrying the goods 300 in the shrink film 220 in this inserting operation.

(59) When the goods 300 reaches a predetermined position in the shrink film 220, the negative air pressure applied to the object suction section 123 via the negative pressure pump connection section 125 is stopped. When the suction applied to the goods 300 is stopped, the goods 300 are released and stay at this position. This operation is executed as one of relative motion of the inserting operation to be described later.

(60) The insertion guide body 120 further keeps on sliding back to an initial setting position consecutively. Of course, it is possible that the slider device 130 is temporarily stopped when the goods 300 reach a predetermined position in the shrink film 220. After ensuring the position of the goods 300 in a predetermined position, then the slider device 130 restarts the slide motion and slides back to an initial setting position.

(61) Next, the shrink film suction part 140 is described.

(62) The shrink film suction part 140 has an air suction part at its tip, and a negative pressure supply mechanism (not shown) for supplying negative air pressure to the air suction part 140. The switching ON/OFF of the air suction force at the tip of the shrink film suction part 140 can be controlled.

(63) As shown in FIG. 1, the shrink film suction part 140 is arranged above the mounting device 110 just below the opening of the shrink film 220. The shrink film suction part 140 is provided with a lifting mechanism (not shown) that vertically moves up and down. The shrink film suction part 140 relates to the sliding motion of the insertion guide body 120 by the slider device 130. The shrink film suction part 140 descends toward the vicinity of the opening of the shrink film 220 prior to the inserting preparation operation and contacts with the shrink film 220 around its opening. While suctioning the opening of the shrink film 220, the shrink film suction part 140 rises to lift up the opening of the shrink film 220. As a result, the opening of the shrink film 220 is largely opened, and the object suction part 123 at the tip of the insertion guide body 120 can be easily inserted into the opening of the shrink film 220.

(64) When the insertion guide body 120 enters the opening of the shrink film 220, the shrink film suction part 140 stops air suction to release the shrink film 220.

(65) Next, a flow of operation of the automatic insertion device 100 for the mount equipped shrink film package according to Embodiment 1 is described. In FIG. 3 to 11, drawing (a) shows a side view, and drawing (b) shows a top view showing from upper side.

(66) FIG. 3 is a schematic view showing an initial state of the stroke of the operation of the automatic insertion device 100 for the mount equipped shrink film package according to the Embodiment 1 of the present invention.

(67) The initial state is similar to that of FIG. 1. The mount equipped shrink film package 200 and the goods 300 are arranged at a predetermined position on the mounting device 110. As shown in FIG. 3 (b), the shrink film 220 of the mount equipped shrink film package 200 and the goods 300 are arranged in series along the inserting direction by the mounting device 110 as shown in FIG. 3 (a). The distance between the shrink film 220 of the mount equipped shrink film package 200 and the goods 300 is narrower than the length of the head part 121 of the insertion guide body 120.

(68) First, as shown in FIG. 4, prior to the start of the inserting preparation operation, the shrink film suction part 140 descends toward the vicinity of the opening of the shrink film 220 of the mount equipped shrink film package 200 by the lifting mechanism. A negative air pressure is applied to the suction part at the tip of the shrink film suction part 140. The shrink film suction part 140 contacts with the shrink film 220 around its opening, and the shrink film 220 is firmly suctioned by the shrink film suction part 140.

(69) Next, as shown in FIG. 5 (a), the shrink film suction part 140 is raised to a height (outer diameter) of the head part 121 of the insertion guide body 120 by the lifting mechanism. The shrink film suction part 140 keeps on applying the air suction by the suction part, raises only the upper side of the opening of the shrink film 220. The lower side of the opening of the shrink film 220 adhered to the mount 210 and the mount 210 remains on the mounting device 110. Thus, the opening of the shrink film 220 is opened.

(70) Next, the inserting preparation operation starts.

(71) The inserting preparation operation is an operation for bulging the shrink film 220 by inserting the insertion guide body 120 into the shrink film 220 while blowing air outer direction from the surface of the insertion guide body 120, and bringing the shrink film 220 to a bulging state in which the opening of the shrink film is opened facing the goods 300.

(72) In this case, as shown in FIG. 6, when the inserting preparation operation is started, the slide motion of the slider device 130 is started, and the head part 121 of the insertion guide body 120 is pushed. The goods suction part 123 at the head of the insertion guide body 120 enters the inside of the shrink film 220 from its opening. Since the outer diameter of the goods suction part 123 is smaller than that of the head part 121 of the insertion guide body, the outer diameter of the insertion guide body 120 decreases toward the head, and the following head part 121 is smoothly inserted when the goods suction part 123 at the tip is inserted into the shrink film 220.

(73) Next, as shown in FIG. 7, when the pushing of the insertion guide body 120 by the slider device 130 proceeds, the head part 121 is inserted into the shrink film 220, and the air blowing port 122 is also positioned inside of the shrink film 220. An air pressure is applied from the air pump (not shown) via the air pump connection part 124 to the air blowing port 122 to blow air.

(74) As shown in FIG. 7, when the air blowing port 122 is also positioned inside of the shrink film 220, the internal air pressure of the shrink film 220 becomes high as shown in FIG. 2 (b). The shrink film 220 is bulged in a cylindrical shape. The cylindrical shape is maintained during air flowing between the space of the head part 121 of the insertion guide body 120 and the shrink film 220. The shrink film 220 is bulged in a round shape without bending or generating wrinkle. By the flow of air, the head part 121 and the shrink film 220 are not brought into contact with each other as separated by the air therebetween. The friction force is also reduced, so the head part 121 smoothly advances in the shrink film 220. In this process, the negative pressure of the shrink film suction part 140 is deactivated, and the suction of the shrink film 220 is stopped, so the upper surface of the shrink film 220 is released from the shrink film suction part 140. The shrink film suction part 140 rises to the height of the initial state.

(75) Next, as shown in FIG. 8, when the pushing of the insertion guide body 120 by the slider device 130 proceeds, the front of the head part 121 goes through the shrink film 220, and the goods suction part 123 contacts the goods 300.

(76) In this Embodiment 1, execution of the inserting preparation operation is completed in this stage.

(77) In this Embodiment 1, negative air pressure is applied from the air pump to the goods suction part 123 via a negative pressure pump connection part 125, and air suction force is given to the goods suction part 123. The goods suction part 123 securely suctions the goods 300.

(78) Next, the inserting operation starts.

(79) The inserting operation is an operation for moving either one of the insertion guide body 120 or the goods 300 and the mount equipped shrink film package 300 relative to the other and pulling or pushing the goods 300 to a predetermined position in the shrink film 220.

(80) In this Embodiment 1 of the relative motion in the inserting operation, the mount equipped shrink film package 300 is fixed and the insertion guide body 120 and the goods 300 are moved along the inserting direction. In this configuration example, when the slider device 130 starts back sliding motion and the slider device 130 starts pulling back the insertion guide body 120. The suction force of the goods suction part 123 of the insertion guide body 120 is maintained, so that the goods 300 follow the insertion guide body 120 by the suction force.

(81) As shown in FIG. 9, the edge of the goods 300 approaches the facing opening of the shrink film 220. When the slider device 130 keeps on sliding the insertion guide body 120, the edge of the goods 300 is inserted via the opening of the shrink film 220.

(82) The bulging effect of the shrink film 220 occurring in the vicinity of the end opening of the shrink film 220 is described.

(83) The flows shown by FIG. 12 (a)-FIG. 12 (b)-FIG. 13 (a)-FIG. 13 (b) are the operation for explaining the bulging effect of the shrink film 220 occurring in the vicinity of the end opening of the shrink film 220.

(84) FIG. 12 (a) shows a state in which the edge of the goods 300 is not sufficiently close to the end opening of the shrink film 220 and a little distance remains. As shown in FIG. 12 (a), air is blown out from an air blowing port 122 of the head part 121 of the insertion guide body 120, the surrounding shrink film 220 is in a state of being stretched and bulged. However, the head part 121 and the goods suction part 123 having a tapered shape locate at the end opening of the shrink film 220. The gap is larger than that of side surface of the head part 121 and the shrink film 220, so that the air pressure in the vicinity of the end opening of the shrink film 220 tends to decrease. Therefore, there is a possibility that the shrink film 220 is not sufficient in bulging state.

(85) Next, as shown in FIG. 12 (b), when the edge of the goods 300 approaches near enough to the end opening of the shrink film 220 by the slider device 130, the area and the space of the air flowing out of the shrink film 220 is reduced. As a result, the air pressure in the vicinity of the end opening of the shrink film 220 increases, and the air pressure to bulge the shrink film 220 rises. The shrink film 220 bulges to secure the state in which the shrink film 220 forms the cylindrical shape. In this state, the inner diameter of the end opening of the shrink film 220 is slightly larger than the outer diameter of the goods 300.

(86) Next, as shown in FIG. 13 (a) to (b), the goods 300 are pulled by the slider device 130. When the edge of the goods 300 is inserted into the shrink film 220, air stably flows to the space between the shrink film 220 and the goods 300, and the goods 300 can be smoothly inserted.

(87) The description is continued with reference to FIG. 10.

(88) FIG. 10 is a schematic view showing how the goods 300 are slid and moved in the shrink film 220 in the inserting operation.

(89) As shown in FIG. 10, during the sliding motion of the insertion guide body 120 in the inserting operation, the goods 300 reach a predetermined position in the shrink film 220. For example, the predetermined position is in the vicinity of the center portion of the shrink film 220.

(90) When the goods 300 reach the predetermined position as shown in FIG. 10, application of negative air pressure via the negative pressure pump connection part 125 is stopped, and then the suction by the goods suction part 123 of the insertion guide body 120 is stopped. The goods 300 are released and are put in the predetermined position of the shrink film 220.

(91) At this state, the execution of the inserting operation is completed.

(92) Next, as shown in FIG. 11, when the slide motion of the insertion guide body 120 by the slider device 130 in the inserting operation is completed, the insertion guide body 120 returns to the initial state of the slide stroke shown in FIG. 3. The stroke of the operation is completed.

(93) After that, the currently processed mount equipped shrink film package 200 with the goods 300 is removed from the mounting device 110 and the next stroke is prepared with next mount equipped shrink film package 200 and next goods 300 disposed on the mounting device 110 by the conveyance system (not shown).
