Description

[Technical Field]

[0001] The present invention relates to a cushioning material inserting device, and more particularly to a cushioning material inserting device for inserting cushioning material into the bottom of a container. [Background technology]

[0002] Conventionally, in order to prevent tablets or the like filled in a container from being damaged by vibrations during transportation, etc., a synthetic resin film or the like cut to a predetermined length is inserted as a cushioning material into the upper space of the container filled with tablets or the like (see, for example, Patent Documents 1 to 4, etc.).

[0003] On the other hand, for the same purpose, a cushioning material made of a sheet-like soft synthetic resin foam or the like is inserted into the bottom of the container before it is filled with tablets or the like. In order to accurately insert cushioning material into the bottom of a container, manual work using tweezers has been performed, and a cushioning material insertion device using a suction nozzle (see, for example, Patent Document 5) has been proposed, but all of these methods have problems with the accuracy and reliability of inserting the resilient cushioning material into the bottom of a container.

[0005] The present invention aims to provide a cushioning material insertion device that can accurately and reliably insert cushioning material into the bottom of a container before it is filled with tablets, etc., in consideration of the problems that arise when inserting cushioning material made of a sheet-like soft synthetic resin foam, etc., into the bottom of the container before it is filled with tablets, etc. [Means for solving the problem]

[0006] In order to achieve the above object, the cushioning material insertion device of the present invention is a cushioning material insertion device for inserting cushioning material into the bottom of a container, and is characterized in that it comprises an upper push rod, a holder, an introduction guide, and a lower push rod, and at the cushioning material supply position, the cushioning material is held between the upper push rod and the lower push rod and placed in the holder via the introduction guide, and at the cushioning material insertion position into the container, the holder containing the cushioning material is inserted into the container, and the cushioning material is pushed out of the holder by the upper push rod to insert the cushioning material into the bottom of the container.

[0007] In this case, the inner surface of the introduction guide may be shaped so that the cross-sectional area gradually decreases in the direction in which the cushion material passes.

[0008] The lower end surface of the upper push rod may be flat, and the upper end surface of the lower push rod may be hemispherical. [Effects of the Invention]

[0009] According to the cushioning material inserting device of the present invention, cushioning material can be inserted accurately and reliably into the bottom of a container before it is filled with tablets or the like. [Brief explanation of the drawings]

[0010] [Figure 1]1A and 1B show an embodiment of a cushioning material inserting device of the present invention, in which FIG. 1A is an explanatory view of a cushioning material supply position, and FIGS. 1B and 1C are explanatory views of a cushioning material insertion position into a container. [Figure 2] 10A to 10C are explanatory diagrams illustrating the operation of the cushion material insertion device. DETAILED DESCRIPTION OF THE INVENTION

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a cushioning inserting device according to the present invention will be described with reference to the drawings.

[0012] 1 and 2 show an embodiment of a cushion inserting device according to the present invention. This cushion material insertion device is a cushion material insertion device for inserting cushion material C made of a sheet-like soft synthetic resin foam, for example, polyethylene resin foam, into the bottom of container B, and is equipped with an upper push rod 1, a holder 2, an introduction guide 3, and a lower push rod 4. At the cushion material C supply position, cushion material C is held between the upper push rod 1 and the lower push rod 4 and contained in holder 2 via introduction guide 3. At the cushion material C insertion position into container B, holder 2 containing cushion material C is inserted into container B, and cushion material C is pushed out of holder 2 by upper push rod 1, inserting cushion material C into the bottom of container B.

[0013] Here, at least the upper push rod 1, holder 2 and lower push rod 4 that constitute the cushioning material insertion device are provided with a movement mechanism (actuator) (not shown) for independently moving them vertically based on the introduction guide 3. In addition, the upper push rod 1 and holder 2 can be provided with a container B supply mechanism 6 for placing container B instead of the cushion material C supply mechanism 5 and introduction guide 3, or can be provided with a moving mechanism (actuator) (not shown) for selectively moving between a cushion material C supply position (cushion material C supply position of the cushion material C supply mechanism 5) and an insertion position of cushion material C into container B (container B supply position of the container B supply mechanism 6).

[0014] The inner surface of the introduction guide 3 is formed in a shape in which the cross-sectional area gradually decreases upward, which is the direction in which the cushioning material C passes, for example, in the shape of a truncated cone with an apex angle of 30° or a trumpet shape (with the lower end open).

[0015] The lower end surface of the upper push rod 1 is formed in a flat shape, and the upper end surface of the lower push rod 4 is formed in a semi-spherical shape.

[0016] The holder 2 is formed in a cylindrical shape with an open bottom end face, and the height dimension is set to a length that allows the cushion material C to be accommodated within the holder 2. In addition, the upper part of the holder 2 is formed in a cylindrical shape that opens into the inside of the holder 2, which functions as a guide when the upper push rod 1 moves (slides) in the vertical direction, and also allows the upper push rod 1 to pass through the opening into the inside of the holder 2.

[0017] Next, the operation and function of this cushioning material inserting device will be described. As shown in Figures 1(a) and 2(1), this cushioning material insertion device, at the supply position of the cushioning material C, holds the cushioning material C supplied to a position below the introduction guide 3 by a supply mechanism 5 of the cushioning material C between an upper push rod 1 and a lower push rod 4 as shown in Figure 2(2). In this state, as shown in Figures 2(3) to 2(4), the device is housed in the holder 2 as shown in Figure 2(5) via the introduction guide 3, and the holder 2 is then pulled up as shown in Figure 2(6). Here, the inner surface of the introduction guide 3 is formed into a shape in which the cross-sectional area gradually decreases upward, which is the direction in which the cushion material C passes, and the lower end surface of the upper push rod 1 is formed into a flat shape, and the upper end surface of the lower push rod 4 is formed into a hemispherical shape, so that the cushion material C is securely clamped between the upper push rod 1 and the lower push rod 4, and the cushion material C can be stored in the holder 2 in an upwardly convex state.

[0018] Next, as shown in Figures 1(b) to (c) and Figure 2(7), at the insertion position of the cushion material C into the container B, instead of the cushion material C supply mechanism 5 and introduction guide 3, a holder 2 containing cushion material C is inserted into the container B supplied by the container B supply mechanism 6 (when the holder 2 enters the area near the bottom of the container B, the holder 2 and cushion material C do not come into contact with the bottom of the container B). In this state, as shown in Figure 2(8), the upper push rod 1 pushes out the cushion material C from within the holder 2 so that the cushion material C is inserted and placed at the bottom of the container B, and then the holder 2 is pulled up as shown in Figure 2(9). Here, the container B supplied by the supply mechanism 6 is positioned on the outer periphery of the holder 2 and is held in a fixed position by a holding mechanism 7 for the container B which is movable up and down relative to the holder 2. Furthermore, by forming the holder 2 into a cylindrical shape with an open bottom end and setting the height dimension to a length that allows the cushion material C to be accommodated within the holder 2, the cushion material C accommodated within the holder 2 can be inserted into the container B without the cushion material C coming into contact with the mouth of the container B, and the cushion material C can be securely placed at the bottom of the container B simply by pushing the cushion material C out of the holder 2 with the upper push rod 1 and inserting it into the bottom of the container B.

[0019] In this way, the cushioning material C can be inserted accurately and reliably into the bottom of the container B before it is filled with tablets or the like.

[0020] The cushioning material insertion device of the present invention has been described above based on its embodiment, but the present invention is not limited to the configuration described in the above embodiment, and the configuration can be changed as appropriate within the scope of the spirit of the present invention. [Industrial Applicability]

[0021] The cushioning material insertion device of the present invention can accurately and reliably insert cushioning material into the bottom of a container before it is filled with tablets or the like, and therefore can be suitably used as a cushioning material insertion device for inserting cushioning material into the bottom of a container.
