Description

  The present invention relates to a vending machine, in particular, a heat-insulated indoor space in a vending machine main body in which a product storage device is disposed or a product storage device, and a region where the temperature is adjusted (warming or cooling) and a region where the temperature is not adjusted. It relates to vending machines that divide up and down.

  As a structure for preventing deterioration due to long-term heating of the product, in Patent Documents 1 to 3, etc., the product storage device provided with a plurality of rows of conveyance paths extending downward from above is divided into two vertically, A structure is disclosed in which a heat-insulating flapper that can be freely opened and closed is provided at these boundary portions, and is partitioned into an upper product storage region and a lower product storage region. At a location facing the lower end of each product storage area, a product delivery mechanism is provided for delivering the products at the lower end of each conveyance path provided in the product storage area one by one downward. That is, in this type of vending machine, not only the product dispensing mechanism is disposed at the lower end of the lower product storage area, but also the lower end of the upper product storage area, that is, the approximately vertical position in the vertical direction of the product storage device. A product delivery mechanism is also provided.

  According to this structure, since the inside of the product storage device is divided into the upper product storage region and the lower product storage region, the upper product storage region is divided even when the product is heated and sold. By heating only the lower product storage area and adjusting the temperature (temperature control) without heating the inside, it is possible to prevent deterioration due to heating while the product is stored in the upper product storage area. As a result, deterioration due to long-term heating of products to be sold (for example, products containing milk components) can be minimized. In addition, since the interior of the lower product storage area is heated, the products to be sold are heated and sold well while being stored in the lower product storage area. In addition, the temperature of the lower product storage area is adjusted (heating and cooling) and the upper product storage area does not need to be adjusted. This is advantageous in that it can save energy.

  Note that the arrangement structure of the heat shield flapper (heat shield flapper) that partitions the product storage device into an upper product storage area and a lower product storage area is shown in FIGS. 29 (a) and 29 (b) in Patent Document 1 and the like. As shown, left and right heat insulation flappers 122A urged by a spring 121 so as to rotate upward to a substantially horizontal posture are disposed horizontally so that their front ends are close to each other (so-called double-spread type) Is disclosed. In FIGS. 29A and 29B, reference numeral 123 denotes a rack frame that is an outer frame of a product storage rack provided with two rows of product transport passages, and 124 denotes a heat-insulating flapper 122A that can rotate freely. It is a support shaft to support. Moreover, about the heat insulation flapper 122A, the state at the time of closing is shown by the continuous line, and the state at the time of opening is shown by the dotted line.

  Here, the reason why the left and right heat-insulating flappers 122A are arranged with a gap between their front ends even when they are closed is because the front ends of the heat-insulating flappers 122A are in contact with each other when they are closed and are horizontal. In this case, due to thermal expansion or manufacturing errors during manufacturing, the heat-insulating flapper 122A may be in a state of abutting against each other in a bad posture, such as being twisted. This is because product clogging may occur. Therefore, in order not to cause such a problem, the horizontal posture is provided with a gap.

  Moreover, as another example of the arrangement structure of the heat shield flapper which partitions the inside of the product storage device into the upper product storage region and the lower product storage region, in Patent Document 3 and the like, as shown in FIGS. 30 (a) and 30 (b). Thus, what arrange | positioned the thermal insulation flapper 122B on either side so that the front-end | tip parts may overlap is disclosed.

  29 and FIG. 30, if the side surfaces of the heat insulation flappers 122A and 122B are in sliding contact with the inner wall surface of the rack frame 123 without any gap, the heat insulation is caused by the friction of the sliding contact portion. Since the flappers 122A and 122B may not be opened and closed satisfactorily, as shown in FIGS. 29B and 30B, between the side surfaces of the heat-insulating flappers 122A and 122B and the inner wall surface of the rack frame 123. The gap x is disposed.

  By the way, in a so-called serpentine vending machine that sells products with temperature control, the product storage device is stored in the vending machine body at the time of product sales or product replenishment. When carrying out maintenance work on the product storage device, the product storage device must be pulled out so that the staff can work, so a slide rail device is attached to the underside of the ceiling of the vending machine, and along this slide rail device The product storage device can be pulled out from the vending machine body. However, when the product storage device is pulled out from the vending machine main body side, the product storage device is detached from the slide rail part on the vending machine main body side. It is generally performed to disassemble (perform maintenance work), for example, by placing it on the surface.

  However, with such a structure, when performing maintenance work, it is necessary to search for a place where the product storage device is placed each time, and there is a drawback that it takes a lot of time and effort. In addition, a suitable placement location may not be found. In this case, the maintenance work is hindered. In addition, as described above, in the case of a vending machine having a structure in which the inside of the product storage device is divided into two parts by a heat-insulating flapper or the like, the structure is more complicated than that of a general vending machine. However, more labor and time are required, and it may be difficult to secure a maintenance work place.

  On the other hand, a vending machine that sells paper-packed goods has a structure in which the product storage device is pulled out to replenish the product from the side, and the product storage device is used not only for maintenance of the vending machine but also for replenishment of the product. The product storage device can be pulled out from the vending machine main body along the guide rail device attached to the inner surface of the ceiling of the vending machine, and when the product storage device is pulled out The hanging posture can be maintained.

Therefore, it is conceivable to apply a structure that can maintain the hanging posture even when the product storage device is pulled out from the vending machine main body to a so-called serpentine type vending machine. Thus, during maintenance, maintenance work can be performed without searching for a place to place the product storage device, and work efficiency is improved. Patent Document 4 simply shows a structure including this type of guide rail device.

  Patent Documents 1 and 2 disclose a structure in which the inside of a product storage device is divided into an upper product storage region and a lower product storage region by a heat shield flapper and the like, and only the lower product storage region is temperature-controlled. However, there is no practical and specific proposal for a structure that shields the gap between the wall surface of the heat insulating chamber in which the product storage device is disposed and the product storage device.

  In this type of vending machine, it is desirable to arrange the product storage device so that it can be withdrawn from the vending machine main body so that maintenance work can be performed easily. As a structure that closes the gap between the inner wall surface of the heat insulation chamber and the product storage device while dividing, for example, a heat shield wall that extends horizontally in the front-rear direction and the horizontal direction is used as the inner wall surface of the heat insulation chamber and the product storage It is conceivable to arrange it so as to straddle the device. More specifically, a heat insulating chamber side heat shield wall that extends inward toward the side surface of the product storage device is formed on the inner wall side surface of the heat insulating chamber so as to extend horizontally in the lateral direction and the front-rear direction. Further, the storage device side heat shield wall extending outward from the side surface portion of the product storage device toward the inner wall side surface of the heat insulation chamber is positioned close to the heat insulation chamber side heat shield wall with respect to the front-rear direction and the lateral direction. It is formed to extend horizontally. Then, seal parts such as sponges and packings are attached to at least one of the heat shield walls so as to fill the gap between the heat shield walls, and the product storage device is stored in the vending machine main body. In the posture, the seal component is disposed so as to contact the storage device side heat shield wall (or the heat insulation chamber side heat shield wall) facing the seal component.

  According to this structure, it is possible to divide the heat-insulating chamber into two vertically divided by the heat-shielding walls (specifically, the heat-insulating chamber-side heat-shielding walls, the storage device-side heat-shielding walls, and the seal parts), and at the time of maintenance The product storage device can be pulled out from the vending machine main body.

  However, in this structure, since the seal component is brought into contact with the storage device side heat shield wall or the heat insulation chamber side heat shield wall only by its elastic force, it becomes easy to generate a gap between them during long-term use, etc. When the gap is generated, the heat insulating performance is deteriorated, and as a result, there is a possibility that deterioration due to long-term heating of a product to be sold (for example, a product containing a milk component) cannot be minimized.

  In addition, as shown in FIGS. 29 (a) and 29 (b), the left and right heat insulating flappers 122A are arranged at the front end portions as shown in FIGS. In the case of being disposed horizontally so as to be close to each other, even when closed, there is a gap between the tip portions of the left and right heat shield flappers 122A, so air in the lower product storage area escapes from the gap to the upper product storage area. Further, there is a drawback that the upper product storage area is also heated, and deterioration of the product in the upper product storage area cannot be prevented.

  On the other hand, as shown in FIGS. 30 (a) and 30 (b), when the left and right heat shield flappers 122B are horizontally arranged so that their tip portions overlap each other, the heat shield flapper 122B can be Since no gap is generated between the tip portions, air and heat can be prevented from escaping (moving) from between the tip portions. However, at the time of closing, the tip portions of the left and right heat shield flappers 122B do not overlap well, and in some cases, the tip portions of the left and right heat shield flappers 122B collide with each other (FIGS. 30A and 30B). ), The posture when the heat shield flapper 122B is closed becomes unstable. In addition, there is a possibility that the posture of the heat-insulating flapper 122B cannot be controlled to be satisfactorily overlapped due to thermal expansion or manufacturing error during manufacturing.

  Further, in any of the structures shown in FIGS. 29 and 30, a gap x (FIGS. 29B and 30B) is provided between the side surfaces of the heat insulating flappers 122A and 122B and the inner wall surface of the rack frame 123. Therefore, the air in the lower product storage area escapes to the upper product storage area from the gap x between them, and the upper product storage area is also heated, thereby deteriorating the product in the upper product storage area. There was a drawback that could not be prevented.

  The present invention solves the above-mentioned problem, and can perform maintenance work well, while at the same time maintaining the heat insulation performance between the heat insulation indoor wall surface and the product storage device in the heat insulation room in a vertical direction. An object of the present invention is to provide a vending machine that can be divided well.

  Another object of the present invention is to provide a heat-insulating flapper and a vending machine that can favorably maintain the heat-shielding performance at a location where the heat-insulating flapper is disposed.

  In order to solve the above-mentioned problems, the present invention provides a vending machine main body in which a plurality of rows of conveyance passages extending from the upper side to the lower side are provided in a heat insulating chamber arranged in the main body of the vending machine. It is arranged in such a way that it can be pulled out and pushed back and forth from the stored attitude stored in the drawer to the front side pulled out from the vending machine main body, and the space inside the product storage device is opened and closed at the middle part of each conveyance path. A heat flapper partitions the upper product storage area and the lower product storage area in a vertically divided state, and the space outside the product storage device in the heat insulation chamber is partitioned in a vertically divided state by a heat shield wall. The heat shield wall provided on the heat shield wall portion is disposed in an inclined posture that is upwardly toward the rear, and the product storage device faces the storage posture side toward the heat shield wall portion.
