Abstract
A wrapping apparatus comprises a plurality of buckets (3) conveyed one by one at intervals, a lower wrapping film (7) spread on the plurality of buckets, and an upper wrapping film (10) overing objects (2) on mount portions (4) of the buckets from above through the lower wrapping film. Each of the buckets has side walls (5) for preventing the objects from falling when the objects are wrapped in the upper and lower wrapping films, and functions as a tray. According to the apparatus, since a tray which is used in conventional wrapping of objects, such as fresh products, is not necessary, it is possible to avoid wasteful use of a tray and to reduce production cost.
Description
- The present invention relates to a wrapping apparatus suited for wrapping a plurality of objects to be wrapped, particularly, fresh products.
- For example, a plurality of fresh products are likely to be shipped and sold while being wrapped in a wrapping film as a package.
- In order to automatically wrap many fresh products in a wrapping film, it is necessary to wrap these fresh products in a stable state in a wrapping operation. Conventionally, a predetermined number of fresh products are collected on one of trays which are conveyed one by one by a transport device, such as a conveyor, and both the fresh products and the tray are wrapped in a film.
- However, the user who bought the fresh products thus wrapped is required to unseal the film and dispose of the tray before eating the fresh products. Refuse disposal has lately attracted considerable attention as a social problem, and such disposal of the tray is not preferable.
- Furthermore, since it is necessary to prepare trays in accordance with wrapping materials for wrapping a plurality of fresh products, production cost is high.
- With the above problems in view, an object of the present invention is to serve to solve a refuse disposal problem and reduce production cost by wrapping a plurality of objects without using any tray.
- According to one aspect of the present invention, there is provided a wrapping apparatus which comprises a plurality of
buckets 3 conveyed one by one at intervals, alower wrapping film 7 spread on the plurality ofbuckets 3, and anupper wrapping film 10 for coveringobjects 2 laid onmount portions 4 of thebuckets 3 from above through thelower wrapping film 7. Each of thebuckets 3 has aside wall 5 for preventing theobjects 2 from falling when theobjects 2 are wrapped in the upper andlower wrapping films - It is preferable to movably mount a
side wall 5c of thebucket 3 so that the area of themount portion 4 can be changed. - According to the apparatus having the above construction, if a predetermined number of objects to be wrapped are laid on the
bucket 3 on which thelower wrapping film 7 is spread, theobjects 2 are prevented from falling by theside wall 5 and held in a stable state. - Since the
objects 2 are wrapped in the upper andlower wrapping films bucket 3 in a stable state, thebucket 3 functions as a tray, and a tray which is necessary in conventional wrapping is not necessary. - Furthermore, if the
side wall 5c of thebucket 3 is movable, it is possible to flexibly cope with a change in the number or kind ofobjects 2 laid on thebucket 3 by changing the area of themount portion 4 while moving theside wall 5c. -

- Fig. 2 is a top view of a bucket on which objects to be wrapped are laid according to an embodiment of the present invention;
- Fig. 3(a) is a perspective view of a bucket according to another embodiment of the present invention;
- Fig. 3(b) is a cross-sectional view of the bucket;
- Fig. 4 is a perspective view of the bucket;
- Figs. 5(a) to 5(d) are top views showing the state in which objects to be wrapped are laid on the bucket; and
- Fig. 6 is a perspective view of a bucket according to still another embodiment.
- Preferred embodiments of the present invention will now be described.
- Referring to Fig. 1, a
conveyor 1 is cyclically movable and rotated by a drive mechanism (not shown) in a direction indicated by an arrow. - A plurality of
buckets 3 for layingfresh products 2 thereon are mounted at regular intervals on theconveyor 1 through supportingshafts 9. Each of thebuckets 3 is in the shape of a rectangular plate, and composed of aflat mount portion 4 andside walls 5 which diagonally extend upward from the peripheral edges of themount portion 4. - The area of the
mount portion 4 is properly set in consideration of the shape and number of thefresh products 2 to be laid thereon. Theside walls 5 are continuously mounted in order to prevent thefresh products 2 from falling by abutting against thefresh products 2 when thefresh products 2 are wrapped in upper andlower films side walls 5 can also be appropriately set. - The
lower wrapping film 7 shrinks at low temperature, is wound in the shape of a roll, and set at one side of the conveyor 1 (upstream in the direction in which thebucket 3 moves on the conveyor 1). Thelower wrapping film 7 is rotatably supported by ashaft 8 to be sent out so that one end of thelower wrapping film 7 is laid on themount portion 4 of thebucket 3 located upstream. - The width of the
lower wrapping film 7 is set longer than the space between theside walls 5 of thebucket 3 opposite to each other. - The
upper wrapping film 10 is made of the same material and has the same width as those of thelower wrapping film 7, located above theconveyor 1, and is rotatably supported by ashaft 11 to be sent out and cover thefresh products 2 laid on thebucket 3. - A three
side heat sealer 12 has three sides and is vertically movable so as to weld and fuse by heat the upper andlower wrapping films fresh products 2 laid on thebucket 3. - A
shrink tunnel 13 shrinks by heat the upper andlower wrapping films fresh products 12 wrapped in the upper andlower wrapping films shrink tunnel 13 while laid on thebucket 3, and is located downstream from theheat sealer 12. - The wrapping of the
fresh products 2 in the wrapping apparatus having the above construction will now be described. - First, one end of the
lower wrapping film 7 is spread on thebucket 3 located upstream of theconveyor 1 which is rotatably driven, and a predetermined number offresh products 2 are supplied onto thebucket 3 by an automatic supply device (not shown). The supplied fresh products are laid on themount portion 4 of thebucket 3 through thelower wrapping film 7, abut against theside walls 5 as shown in Fig. 2 without falling, and do not move in thebucket 3. - One end of the
upper wrapping film 10 is welded to one end of thelower wrapping film 7 previous to the operation of theconveyor 1, and the upper andlower wrapping films bucket 3 on which thefresh products 2 are laid. - When the
bucket 3 reaches below theheat sealer 12, theheat sealer 12 descends, welds and fuses by heat the peripheral edges of the upper andlower wrapping films fresh products 2. Thefresh products 2 wrapped in the upper andlower wrapping films shrink tunnel 13, and the upper andlower wrapping films shrink tunnel 13. - Since the
shrunk films fresh products 2 in a tension state, thefresh products 2 do not move and the state at wrapping is maintained. - The
fresh products 2 thus wrapped by shrinking fall as apackage 20 from thebucket 3 downstream of theconveyor 1, and are conveyed into a subsequent process, such as packing, by an unillustrated conveyor. - The above wrapping of the
fresh products 2 is sequentially performed on eachbucket 3. - Although the
bucket 3 is in the shape of a plate in the above embodiment, as shown in Figs. 3(a) and 3(b), themount portion 4 tilting in the advance direction of thebucket 3 and left andright side walls 5a and arear side wall 5b may be constituted by a pair of left andright frames 25 and a plurality ofextensible connecting rods 26 connected to theframes 25 so that the area of themount portion 4 can be changed in accordance with the size, number and kind of thefresh products 2. - Furthermore, since the
bucket 3 tilts upward at its front side and the width of thebucket 3 is adjustable, it is possible to wrap thefresh products 2 regardless of the number of thefresh products 2 while thefresh products 2 are abutting against therear side wall 5b. Therefore, it is possible to immediately cope with a change in number of thefresh products 2 to be wrapped and to avoid wasteful use of wrapping films. The tilt angle of themount portion 4 can be changed by rotating thebucket 3 on aslide shaft 28. - The
bucket 3 may be set as shown in Figs. 4 to 6. - Referring to Fig. 4, a
movable side wall 5c has a supportingportion 16. Abolt 18 is inserted through the supportingportion 16 and an extendedhole 17 formed on themount portion 4 at the front thereof in the advance direction, and engages one end of the supportingshaft 9 while fastening themovable side wall 5c and themount portion 4 together. - The
movable side wall 5c can be moved along the extendedhole 17 and rotated on thebolt 18 as indicated by virtual lines by unfastening thebolt 18. - Furthermore, the left and
right side walls 5 may also be movable. In this case, thefresh products 2 can be wrapped in manners as shown in Fig. 5(a) to 5(d). - The
bucket 3 may be divided into four parts as shown in Fig. 6 so as to be extensible. - As the upper and
lower wrapping films shrink tunnel 13 is not necessary. - It is obvious that the details of construction of parts described in the present invention can be arbitrarily changed and that the
objects 2 to be wrapped are not limited to fresh products. - As described above, according to the present invention, since the bucket on which objects to be wrapped are laid through the lower wrapping film has the side walls, the objects can be wrapped on the bucket in a stable state.
- As a result, even if a plurality of objects are collected and wrapped, there is no need to use any tray used in conventional wrapping. Therefore, a wrapping apparatus can serve to solve the refuse disposal problem and is extremely practical.
- Furthermore, since the objects can be wrapped without using a tray as described above, production cost can be reduced.
- In addition, if the side walls of the bucket are movable so that the area of the mount portion can be changed, it is possible to flexibly cope with a change in number or kind of objects laid on the bucket.
