Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an empty can press machine that can be suitably used as an accessory device in a system kitchen, a vending machine, or the like.

[0002]

[Prior art]

 Conventional empty can pressing machines are known in which an empty can is pressed by a hydraulic cylinder or a pneumatic cylinder, or manually pressed by using the lever principle.

However, in an empty can press machine operated by a hydraulic cylinder or a pneumatic cylinder, a hydraulic device or a pneumatic device for operating the cylinder device is required, which is a large-scale device, so that the system cannot be used. There is a problem that it is difficult to install it as an auxiliary device such as a kitchen.On the other hand, the manual device is easy to use, but it is used because it takes time and labor to press it. There was a problem that it was difficult.

Therefore, the applicant of the present application has previously disclosed in Japanese Patent Application No. 4-86712 an empty can between a press member and a back pressure member, which are moved forward and backward by a transmission through linear movement conversion means. We have proposed an empty can pressing machine with a compact structure that allows it to be pressed and operated easily with a commercial power source for general households.

A configuration example thereof will be described with reference to FIG. 11. The press chamber 41 into which the empty can C is loaded has a fixed frame 42 having a planar U-shape and a fixed frame 4 formed by a linear movement conversion means 43. It is composed of a press member 44 that moves forward and backward in 2 and an empty can receiver 45 fixed to the lower end of the press member 44. The ends of both side walls 42a of the fixed frame 42 are fixed to the frame 46. Further, an empty can drop opening 47 is opened in a portion of the empty can receiver 45 adjacent to the press member 44, and after the press member 44 has moved to the forward end, when the backward withdrawal is started, the press member 44 and the fixed frame 42 are separated from each other. The empty can C pressed between the two falls.

[0006]

[Problems to be solved by the device]

 However, in the empty can press machine configured as shown in FIG. 11, when the empty can C is placed in the center of the press chamber 41, no problem occurs in the pressing operation of the empty can C. When the empty can C is loaded with a bias, as shown in FIG. 12, one end of the empty can C is placed on the side wall 42a of the fixed frame 42 and the side end of the pressing member 44 during the forward movement of the pressing member 44. The empty can C may not be pressed flatly, may not fall from the empty can drop port 47 and may remain in the press chamber 41, or the press member 44 may not move. There was a problem such as a breakdown.

In view of the above conventional problems, an object of the present invention is to propose an empty can pressing machine that can reliably press flat cans even when empty cans are loaded in the press chamber with a bias. To do.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention, if indicated by reference numerals in the figure, is, in claim 1, a press chamber at a lower part of a chute 2 which is connected to an inlet 1 of an empty can C. 3, the press chamber 3 is provided with a fixed frame 7 having a planar U-shape, a press member 6 that moves forward and backward in the fixed frame 7, and an empty can C put in the press chamber 3. Consists of an empty can receiver 8 provided with an empty can drop opening 9 that moves in conjunction with the press member 6 to open the space between the fixed frame 7 and the press member 6 downward at the forward end of the press member 6. Then, at least one side edge of the press member 6 is provided with a restricting piece 35 which can be oscillated and displaced toward the inside of the press chamber 3, and the fixing frame 7 is allowed to pass the restricting piece 35 accompanying the movement of the press member 6. The notch 39 is provided, and the regulating piece 35 is swung in the press chamber 3 in conjunction with the movement of the press member 6. It also adopts a configuration comprising a means.

Further, according to the second aspect, the restriction piece 35 is attached to the press member 36 via the elastic body 36 so as to be swingable, and the cam projection 37 is provided on the back surface of the restriction piece 35.

[Action]

 According to claim 1 of the present invention, when the empty can C is put into the press chamber 3 and the press member 6 is moved forward, the empty can C is pressed between the press member 6 and the fixed frame 7, In this case, even if the empty can C is thrown in with an offset, the restricting piece 35 provided on the side edge of the empty can C swings toward the press chamber 3 in association with the movement of the pressing member 6. Since C is pushed toward the central portion, there is no fear that the empty can C will bite into the gap between the side edge of the press member 6 and the side wall 7a of the fixed frame 7, and the empty can C can be surely pressed into a flat shape. As a result, it can be dropped downward from the press chamber 3 through the empty can drop port 9, and no failure due to the biting of the empty can C can be eliminated.

According to the second aspect, when the press member 6 moves forward, the cam projection 37 on the back surface of the restriction piece 35 engages with the hitting metal fitting 38 fixed to the fixed frame 7, and the restriction piece 35 moves. Since it elastically oscillates inwardly, the restriction piece 35 can be oscillated toward the inside of the press chamber 3 with the movement of the press member 6 with a simple structure without providing a special interlocking mechanism. it can.

Further, when it is fixed to the above, it is composed of an empty can holder 8 extending horizontally in the lower part of the fixed frame 7. The front ends of the both side walls 7a of the fixed frame 7 are fixed to the front surface of the front support plate 22 of the pair of support plates 22 and 22 which are erected on the rear portion of the horizontal partition wall 21 with a proper space in the front and rear. The pressing member 6 is driven by a geared motor (electric motor) 4 attached to the rear surface of the rear support plate 22 via a linear movement converting means 5. By thus moving the press member 6 via the linear movement converting means 5 by the geared motor 4, it is not necessary to use a large-scale hydraulic mechanism or pneumatic mechanism, and a compact structure can be achieved. Since it can be easily stored in any case and can be operated by a commercial power source, it can be easily installed in general households.

Explaining the linear movement converting means 5, the guide cylinder 23 is fixed to the pair of support plates 22, 22, and the distal end of the movable cylinder 26 movably inserted into the guide cylinder 23 is fixed to the press member 6. Has been done. In addition, a guide pin 24 protrudingly provided on the outer peripheral surface of the movable barrel 26 is fitted into an elongated hole 25 formed in the guide barrel 23, and the movable barrel 26 is supported so as to be movable only in a straight line without rotating. Further, the male screw shaft 28 is screwed into the female screw portion 26a formed on the inner surface thereof. The male screw shaft 28 is rotatably supported by the rear support plate 22 via the thrust bearing 27 and is integrally connected to the drive shaft of the geared motor 4.

As shown in FIGS. 3, 4 and 7, the empty can receiver 8 has a receiving plate 10 in which an empty can drop port 9 is opened in a portion adjacent to the press member 6, and the receiving plate 10. It is composed of a pair of empty can receiving projections 11 projecting along the moving direction of the press member 6 on the tip end of the. The empty can receiving projections 11 support the empty cans C put into the press chamber 3 in a state of being slightly lifted from the receiving plate 10. The empty cans C are supported by the upper surface of the receiving plate 10 and the fixing frame during the pressing operation. It is designed so as not to be dragged into the gap between the lower end of 7 and. In addition, a passage groove 12 through which the receiving plate 10 passes and a passage groove 13 through which the empty can receiving projection 11 passes are formed at the lower end of the fixed frame 7.

As shown in FIGS. 5, 6 and 7, a restriction piece 35 is attached to both side edges of the press member 6 via a leaf spring 36 so as to be swingable toward the press chamber 3. There is. In the illustrated example, chamfers 6b inclined inward are formed on both side edges of the pressure plate 6a at the front end of the pressing member 6, and the rear end portions of the restricting pieces 35 are arranged side by side on the outside thereof, so that the side edges of the pressure plate 6a The rear surface of the part and the rear end surface of the restriction piece 35 are connected via a leaf spring 36, and the restriction piece 35 is elastically swingable toward the inside of the press chamber 3. Further, the fixed frame 7 is provided with a notch 39 so as to allow the restriction piece 35 to pass along with the movement of the press member 6. Further, the cam projection 37 is provided on the outer side surface of the restriction piece 35, and the metal fitting 38 with which the cam projection 37 is engaged with the outer surface of the side wall 7a of the fixed frame 7 so as to traverse the notch 39 vertically. Is fixed, and the regulating piece 35 is rocked toward the inside of the press chamber 3 by the engagement of the cam projection 37 and the hitting metal fitting 38 while the regulating piece 35 moves forward in conjunction with the movement of the press member 6. Is made in. The pressure plate 6a is made of a stainless plate to prevent rust.

As shown in FIGS. 3 and 4, the press member 6 has a built-in electromagnet 14 that is excited during forward movement of the press member 6 and demagnetized at its backward movement end. When C is pressed and then the press member 6 is retracted, if the pressed empty can C is made of aluminum, it is not adsorbed by the electromagnet 14 and falls and is recovered in the aluminum can container 17 (see FIG. 9). If the pressed empty can C is made of steel, the empty can C is attracted to the electromagnet 14 and retracts together with the pressing member 6, and the electromagnet 14 is demagnetized when the pressing member 6 reaches the backward moving end. It falls and is collected in the steel canister 18 (see FIG. 10).

As shown in FIG. 3, the empty can inlet 1 is provided with a shutter 15 with a handle 15 a that can be opened and closed through a hinge 30 provided at the lower end edge of the empty can inlet 1, and at the lower end of the shutter 15. , An empty can support plate 31 extending substantially at right angles to the shutter 15 is integrally projected, and when the shutter 15 is opened as shown by a phantom line, the empty can support plate 31 stands up and shoots 2. When the empty can C is inserted between the empty can support plate 31 and the shutter 15 and the shutter 15 is closed (solid line state), the empty can support plate 31 is opened. The cans C fall and are thrown into the press chamber 3 through the chute 2. In this way, the empty cans C are loaded one by one, and it is prevented that the empty cans C exceeding the capacity of the empty can pressing machine P are excessively loaded.

At the upper edge of the empty can inlet 1, a magnet 32 is provided which attracts the shutter 15 to maintain its closed state and also functions as a proximity switch for detecting the attraction of the shutter 15. The geared motor 4 is driven by the detection signal of the proximity switch. Further, when the press member 6 reaches the forward movement end, the current value of the geared motor 4 rises. Therefore, when the control device detects it and the detected value exceeds the set value, the geared motor 4 is rotated in the reverse direction to press. The operation of the geared motor 4 is stopped by a signal from a detector that retracts the member 6 and when the press member 6 reaches the retreat movement end.

In FIG. 3, reference numeral 33 denotes an opening / closing door with a handle 33 a that is openably and closably provided in the opening at the lower front of the main body 16, and is opened by opening it as shown by a phantom line in FIG. The aluminum canister 17 and the steel canister 18 integral therewith can be taken out from the main body 16. Reference numeral 34 is a caster attached to the lower surface of the main body 16.

Next, the procedure of the press work will be described. First, from the state shown by the solid line in FIG. 3, the shutter 15 is opened, the empty can C is put into the charging port 1, and the shutter 15 is closed. As a result, the empty can C is put into the press chamber 3 through the chute 2. At the same time, the closing of the shutter 15 is detected by the magnet 32, the geared motor 4 is operated by the control device based on the detection signal, the male screw shaft 28 of the linear movement converting means 5 rotates, and the moving cylinder 26 moves straight. 3 and moves forward from the state where the press member 6 is located at the backward movement end toward the right side in FIG.

The empty can C put into the press chamber 3 by the forward movement of the pressing member 6 is pinched by the pressing member 6 and the fixed frame 7, and the empty can C is pressed into a flat shape. At this time, as shown in FIG. 8 (a), even if the empty can C is loaded into the press chamber 3 with some deviation, when the press member 6 starts moving, it is provided at its side edge in conjunction with it. By engaging the cam projection 37 of the restricted piece 35 with the contact metal fitting 38, the restricted piece 35 swings toward the inside of the press chamber 3 as shown in FIG. It is pushed toward the center of the press chamber 3. As a result, the empty can C is prevented from biting into the gap between the side edge of the press member 6 and the side wall 7a of the fixed frame 7. Thereafter, as shown in (c) of FIG. 8, the cam projection 37 passes through the metal fitting 38, and the restricting piece 35 returns to its original state by the elastic restoring force of the leaf spring 36. Moves further forward.

Further, since the empty can C is supported by the empty can receiving protrusion 11 in a state of being slightly lifted from the receiving plate 10 during the pressing operation, a gap between the receiving plate 10 and the lower end of the solid frame 7 is provided. The empty can C is not dragged in. Thus, the empty can C is surely pressed into a flat shape.

When the pressing member 6 comes into pressure contact with the fixed frame 7 and the movement of the pressing member 6 approaches a stopped state, the current value flowing through the geared motor 4 increases rapidly. Therefore, if the current value exceeds the set value, control is performed. The geared motor 4 is reversely rotated by the device, and the press member 6 moves backward.

At that time, the electromagnet 14 is excited by the forward movement of the press member 6, but when the empty can C is made of aluminum, it is not adsorbed, so that the empty can drop port 9 and the empty can passage port 20 are directly passed. When the empty can C is made of steel, it is adsorbed by the electromagnet 14 and retracts together with the press member 6, and when the press member 6 reaches the retreat movement end, the electromagnet 14 is dropped. When it is demagnetized, it falls into the steel can 18 (see FIG. 10). As a result, the aluminum empty can C and the steel empty can C are automatically separated.

When the press member 6 reaches the state movement end, the operation of the geared motor 4 is stopped by the signal from the detector that detects it.

In the above-described embodiment, an example in which the restriction pieces 35 are provided on both side ends of the press member 6 is shown, but the empty can C is always biased to one side of the press chamber 3 while passing through the chute 2. In such a case, it may be provided only on one side edge.

In the above embodiment, the empty can press machine P is incorporated in the system kitchen S. However, it may be incorporated in an automatic vending machine or the like, and as a movement driving means for the press member, a linear movement with an electric motor. Although the example using the conversion means is shown, the present invention can be applied to the case of using other driving means.

[Effect of device]

 According to claim 1 of the present invention, a restriction piece is provided on the side edge of the press member, and the restriction piece is rocked toward the press chamber in conjunction with the movement of the press member to move the empty can to the center of the press chamber. Since it is pushed toward the part, even when the empty can is loaded in the press chamber even if it is biased, the empty can is placed in the gap between the side edge of the press member and the side wall of the fixed frame. There is no risk that the empty can will bite, the empty can can be reliably pressed into a flat shape and dropped downward, and no failure due to the biting of the empty can can be eliminated.

According to the second aspect, the cam projection is provided on the back surface of the restricting piece, and the metal fitting is fixed to the fixing frame so that they are engaged with each other when the press member moves forward and the restricting piece elastically moves inward. Since the oscillating displacement is performed, the restricting piece can be oscillated toward the press chamber along with the movement of the press member with a simple structure without providing a special interlocking mechanism.
