Description

Technology Field

[0001] The present invention relates to a packaging container transfer system, and more particularly to a sandwich packaging container transfer system capable of automatically transferring a packaging container containing a sandwich to the next process. Background Technology

[0002] Sandwiches made with ingredients placed between slices of bread are gaining popularity in convenience stores and other places due to their ease of handling and convenience of consumption, and their consumption is also on the rise.

[0003] These sandwiches are mass-produced in food factories and sold in disposable containers. However, sandwiches packaged in paper or plastic containers have the disadvantage of losing their shape or spilling their contents due to external impacts during transportation or handling. Therefore, to enhance the marketability of sandwiches, there is a trend toward distributing and selling them in triangular containers made of sturdy synthetic resin rather than paper or plastic.

[0004] To mass-produce these pre-packaged triangular sandwich products, numerous workers must manually place the finished sandwiches into open-sided triangular packaging containers. Afterward, these containers must be placed into triangular trays and sent to the next process, where the open side is sealed. Since all these tasks are performed manually, there is a problem of increased workload for the workers. Prior art literature

Specific details for implementing the invention

[0017] Hereinafter, an embodiment of the sandwich packaging container conveying system according to the present invention will be described in detail with reference to the attached drawings.

[0018] FIGS. 1 and 2 are perspective views showing a sandwich packaging container conveying system according to the present invention, FIG. 3 is a view showing a conveying blocker of the sandwich packaging container conveying system according to the present invention, and FIGS. 4 to 6 are views showing a packaging container dropping part of the sandwich packaging container conveying system according to the present invention.

[0019] The sandwich packaging container conveying system according to the present invention is configured to convey a triangular packaging container (P) with one side open, which stores a triangular sandwich (S) inside, to the next process, and comprises a frame (10), a first conveyor (20) that rotates inside the frame (10) and conveys the packaging container (P) containing the sandwich (S) forward, a packaging container dropping unit (30) that sequentially receives the packaging container (P) from the first conveyor (20) and drops it, a second conveyor (40) that conveys a tray (T) on which the packaging container (P) dropped by the packaging container dropping unit (30) is placed, and a conveying blocker (50) that temporarily stops the conveying of the packaging container (P) conveyed by the first conveyor (20).

[0020] The first conveyor (20) rotates on the upper side inside the frame (10) and rotates while supporting both ends (i.e., the flange portions of the packaging container) of the packaging container (P) in which the sandwich (S) is stored, thereby transporting the packaging container (P) toward the packaging container drop section (30). Inside this first conveyor (20), inclined surfaces (21) are provided to support the inclined sides of the packaging container (P).

[0021] The above packaging container dropping section (30) is provided in front of the front end of the first conveyor (20), and the packaging container (P) supplied therein remains stationary for a while, then drops downward and is transported forward by the second conveyor (40).

[0022] The packaging container dropping unit (30) comprises a pair of mounting brackets (31) installed spaced apart from each other, a driving motor (32) installed on the frame (10), a cam (33) installed on the motor shaft of the driving motor (32) to increase the distance between the pair of mounting brackets (31), a restoring means (34) to increase the distance between the pair of mounting brackets (31) that has increased by the cam (33), a conveying conveyor (35) installed on each of the pair of mounting brackets (31), and a stopper (36) that limits the conveying distance of the packaging container (P) conveyed by the conveying conveyor (35).

[0023] The above mounting bracket (31) is installed on the frame (10) such that the distance between them can be made farther or closer.

[0024] To elaborate, a pair of mounting brackets (31) are installed facing each other, with a wide gap between the rear portions facing the first conveyor (20) and a narrow gap between the front portions on the opposite side. The gap between these pair of mounting brackets (31) is widened by the operation of the cam (33), and the gap between them is narrowed by the operation of the restoration means (34).

[0025] The cam (33) is installed on the motor shaft of the drive motor (32) and is positioned between the rear portions of a pair of mounting brackets (31). In this state, when the drive motor (32) is operated, the cam (33) rotates together with the motor shaft to increase the distance between the mounting brackets (31).

[0026] As is known, the cam (33) has a small diameter in one direction and a long diameter in the other direction perpendicular to that direction, so when the two ends of the long diameter part touch each of the pair of supports (31), the pair of supports (31) are spread apart.

[0027] The above-mentioned restoring means (34) brings the gap between a pair of mounting brackets (31) that are separated by a cam (33) closer. This restoring means (34) consists of a pair of brackets (34a) spaced apart on the frame (10), a pair of support rods (34b) whose ends penetrate the brackets (34a), and a pair of springs (34c) installed to surround the support rods (34b).

[0028] The above support rod (34b) is provided on each of a pair of mounting brackets (31), with one end connected to the support (51) and the other end supported by passing through a pair of brackets (34a).

[0029] The above spring (34c) is installed between the bracket (34a) and the support (51) to provide a restoring elastic force to the support (51). That is, when a pair of supports (51) move apart from each other by the cam (33), the spring (34c) presses the supports (51) to bring them closer together.

[0030] The above transfer conveyor (35) is installed on a pair of supports (31) and supports both ends (i.e., the flange portions of the packaging container) of the packaging container (P) supplied by the first conveyor (20) to transport the packaging container (P), and when the distance between the pair of supports (31) widens, the support of both ends of the packaging container (P) is released so that the packaging container (P) is dropped onto the tray (T).

[0031] To explain in more detail, the conveyor (35) is composed of front and rear pulleys (35a, 35b), a rotary motor (35c) that rotates the front pulley (35a), and a belt (35d) that rotates around the front and rear pulleys (35a, 35b).

[0032] The above front and rear pulleys (35a, 35b) are each installed to be rotatable in the front and rear directions on the inner surface of the rear portion of a pair of mounting brackets (31).

[0033] The above rotary motor (35c) has a motor shaft connected to the front pulley (35a) and rotates the front pulley (35a).

[0034] The belt (35d) supports both ends of the packaging container (P) to transport the packaging container (P). Since it surrounds the front and rear pulleys (35a, 35b), it rotates together with the front and rear pulleys (35a, 35b) as they rotate, thereby transporting the packaging container (P). While transporting the packaging container (P) in this manner, if the gap between the supports (31) is widened by the cam (33), the packaging container (P) falls and is fed into the tray (T). Once the packaging container (P) containing the sandwich (S) is placed inside the tray (T), it is transferred to the next process, which is to seal the open side of the packaging container (P) with film.

[0035] The above stopper (36) is installed on the frame (10) so that its protrusion length can be adjusted in the front-rear direction, thereby limiting the transport distance of the packaging container (P) transported by the transport conveyor (35).

[0036] To elaborate, one end of the stopper (36) is bolted to the upper surface of the frame (10) and the other end extends toward the first conveyor (20) and comes into contact with the packaging container (P) being transported by the conveyor (35). Therefore, the packaging container (P) is blocked by the stopper (36) and cannot move any further.

[0037] In addition, the stopper (36) has a bolt hole (36a) through which a bolt that is fastened to the frame (10) passes, and the stopper (36) can be fixed by pushing or pulling it in the front-rear direction within the length limit of the bolt hole (36a). This adjusts the protruding length of the stopper (36).

[0038] The second conveyor (40) rotates in the same direction as the first conveyor (20) below the first conveyor (20) and continuously transports a plurality of trays (T). As the trays (T) are transported by the second conveyor (40), they settle the packaging containers (P) falling from the packaging container dropping section (30) inside.

[0039] The above transfer blocker (50) stops the transfer of the packaging container (P) being transported by the first conveyor (20) until the packaging container (P) dropped from the packaging container drop section (30) is placed on the tray (T).

[0040] To explain in more detail, the transfer blocker (50) is composed of a support (51), a cylinder (52) installed on the support (51), a connecting piece (53) installed on the rod of the cylinder (52), and a fixing pin (54) provided on the connecting piece (53).

[0041] The above support (51) is installed at an upper point of the frame (10) where the first conveyor (20) is located, and its overall shape is similar to the Korean character 'ㄷ' which is open downwards.

[0042] The above cylinder (52) is installed at the center of the bottom surface of the support (51). This cylinder (52) is equipped with a rod that moves forward (i.e., rises) and then immediately moves backward (i.e., descends) when the packaging container (P) falling from the packaging container drop section (30) lands on the tray (T).

[0043] The above connecting piece (53) is installed on the rod of the cylinder (52) and moves back and forth together with the rod.

[0044] The above fixing pin (54) is provided one on each side of the bottom surface of the connecting piece (53). These fixing pins (54) are in close contact with the inner wall of the packaging container (P) at the very front among the packaging containers (P) being transported by the first conveyor (20) until the packaging container (P) is seated inside the tray (T), thereby preventing the packaging container (P) from being transported to the packaging container drop section (30).

[0045] That is, the fixing pin (54) prevents the transport of the packaging container located immediately behind the packaging container supplied to the packaging container drop section (30) so that the packaging containers (P) are supplied one by one to the packaging container drop section (30) and then settled on the tray (T).
